Definitions
- the present invention relates to a control device for removing a surface floating layer such as oil, a dust recovery system for launching and recovering it, and a structure mediating them.
- An oil spill is the release of liquid petroleum hydrocarbons into the environment as a result of unintentional human activity.
- 'Oil' may be refined oil, including crude oil, refined petroleum products (gasoline, diesel, etc.), or by-products, bunker oil from ships, and oily waste. Oil spills can take months or even years to clean up.

본 발명은 기름 등의 수면 부유층을 제거하는 방제 장치, 이를 진수 및 회수하는 진회수 시스템, 및 이들을 매개하는 구조물에 관한 것이다.The present invention relates to a control device for removing a surface floating layer such as oil, a dust recovery system for launching and recovering it, and a structure mediating them.
바다나 호수 등의 수면에 오일(기름)이 유출되는 사고가 발생될 경우, 신속하게 방제 작업을 하여 오일이 넓게 퍼져나가는 것을 방지할 필요가 있다.In the event of an accident in which oil (oil) is spilled on the surface of the sea or lake, it is necessary to promptly take action to prevent the oil from spreading widely.
기름 유출은 액체 석유탄화수소를 고의가 아닌 인간의 활동의 결과로 주변환경에 유출하는 것을 말한다. '기름'은 원유를 포함하여 정제된 기름,정제된 석유제품(가솔린,디젤 등),또는 부산물,배의 벙커유,유성의 폐기물이 될 수도 있다. 유출된 기름은 정화에 여러 달에서 여러 해가 걸릴 수도 있다.An oil spill is the release of liquid petroleum hydrocarbons into the environment as a result of unintentional human activity. 'Oil' may be refined oil, including crude oil, refined petroleum products (gasoline, diesel, etc.), or by-products, bunker oil from ships, and oily waste. Oil spills can take months or even years to clean up.
이와 같은 유출된 기름을 제거하기 위해 유화제나 흡습제가 해상에 투입되거나,흡착포를 이용한 제거 또는 자동화된 유수기를 이용한 제거 방법 등이 사용된다In order to remove such spilled oil, an emulsifier or absorbent is put into the sea, or a removal method using an absorbent cloth or an automated water dewatering device is used.
일예로, 이러한 방제작업을 할 때는 오일이 유출된 부위의 둘레부에 오일펜스를 설치한 후, 작업자가 오일펜스의 내부에 부직포 등으로 제작된 사각형의 흡착포를 던져서 흡착포가 오일을 흡수하도록 한 후, 수작업으로 흡착포를 수거하는 방법을 통해 오일을 제거하는 방법이 이용되고 있다.For example, when performing such a control operation, after installing an oil fence on the circumference of the oil spilled area, the operator throws a square absorbent cloth made of non-woven fabric inside the oil fence so that the oil is absorbed by the oil fence , a method of removing oil by manually collecting the absorbent cloth is used.
그런데, 이러한 방법으로 방제작업을 할 경우, 오일이 유출된 부위에 정확히 흡착포를 던져 넣어야 함으로, 넓은 면적에 분포된 오일을 효과적으로 방제하기 어려울 뿐 아니라, 오일을 흡수한 흡착포를 작업자가 수거하여야 하므로, 수거에 시간이 많이 소요되는 문제점이 발생되었다.However, when the control operation is performed in this way, it is difficult to effectively control the oil distributed over a large area because the absorbent cloth must be accurately thrown into the area where the oil spilled, and the operator must collect the absorbent cloth that has absorbed the oil, There was a problem that the collection took a lot of time.
특히, 이와 같이, 작업자가 흡착포를 수작업으로 수거할 때, 작업자가 오일에 노출되며, 특히, 작업자가 오일에서 증발된 유증기를 흡입하여 건강에 문제가 발생되는 문제점이 발생되었다.In particular, in this way, when the worker manually collects the absorbent cloth, the worker is exposed to oil, and in particular, the worker inhales oil vapor evaporated from the oil, resulting in health problems.
따라서, 최근에는 이러한 문제점을 해결하기 위한 다양한 해양방제장치가 개발되어 사용되고 있다.Therefore, recently, various marine control devices have been developed and used to solve these problems.
그런데, 이러한 해양방제장치는 큰 선박에 설치되어 사용됨으로, 이동이 불편하고, 신속하게 현장에 투입하기 어려운 문제점이 있었다.However, since these marine control devices are installed and used on large ships, there are problems in that they are inconvenient to move and difficult to quickly put into the field.
또한, 이러한 해양방제장치는 선박의 운전자가 육안으로 오일이 떠있는 위치를 확인하고, 선박을 오일의 위치로 이동시켜야 하는데, 이와 같이 사람이 육안으로 멀리 떠있는 오일을 확인하는 것이 매우 어려운 문제점이 있었다.In addition, such an offshore control device requires the driver of the ship to visually check the location where the oil is floating and move the ship to the location of the oil. there was.
또한, 이와 같이, 수면에 떠있는 오일을 제어하는 방제작업은 시간이 많이 걸리게 되는데, 전술한 바와 같이, 운전자가 육안으로 오일의 위치를 확인하고 선박을 운전할 경우, 운전자가 쉽게 피로를 느끼게 됨으로, 장시간 지속적으로 방제작업을 할 수 없는 문제점이 발생되었다.In addition, in this way, the control work of controlling the oil floating on the water takes a lot of time. As described above, when the driver visually checks the location of the oil and drives the ship, the driver easily feels fatigued, A problem occurred that preventive work could not be performed continuously for a long time.
흡착포를 이용하는 방법 외에, 자동화된 유수 분리 방식은 위어식 유회수기(Weir Skimmer), 흡착식 유회수기(Oleophilic Skimmer), 컨베이어식 유회수기(Conveyor Skimmer), 원심력식 유회수기(Hydro-Dynamic Skimmer), 이동식 및 고정식(선박 장착형) 유회수기,진공식 유회수기(Vacuum Skimmer) 등이 알려져 있는데,이들 장치는 모두 대형 선박 등에 설치되어 사용된다.In addition to the method using adsorbent cloth, automated oil-water separation methods include weir skimmer, oleophilic skimmer, conveyor skimmer, centrifugal skimmer, and mobile skimmer. And fixed (ship-mounted) skimmers, vacuum skimmers, etc. are known, and all of these devices are installed and used on large ships.
국내에서의 기름 유출 사고는 연 평균 270여회 발생하고 유출되는 기름의 양은 70만L(리터)에 달한다. 대부분의 기름 유출은 100L 이하의 작은 규모 사고이며,이는 전체 사고의 빈도수의 70%를 차지한다. 문제는 기존의 자동화 장비들은모두 고가의 대형 장비로 기름 유종에 따라 다른 장비를 써야 한다는 이유로 대형 기름 유출 사고에 주로 사용되고 작은 규모의 사고는 모두 재래식 노동집약형 작업의 흡착포 작업이 다수를 이룬다.In Korea, an average of 270 oil spill accidents occur annually, and the amount of oil spilled reaches 700,000 L (liter). Most oil spills are small-scale accidents of less than 100L, which account for 70% of the total accident frequency. The problem is that existing automation equipment is all expensive and large equipment, and because different equipment must be used depending on the type of oil, it is mainly used for large-scale oil spill accidents, and all small-scale accidents are made up of conventional labor-intensive absorbent work.
그 과정에서, 전술한 바와 같이, 방제자들에게 기름냄새,두통,허리 통증 등의 산업재해가 발생되며 자연스럽게 노동시간은 늘어나 초동 대처가 힘들어지며 폐기물의 양은 늘어나게 되는 구조이다In the process, as described above, industrial accidents such as the smell of oil, headaches, and back pain occur to control workers, and naturally, working hours increase, making it difficult to cope with the first action and increasing the amount of waste.
따라서, 이러한 문제점을 해결하기 위한 새로운 방법이나 장치가 필요하게 되었으며, 다양한 구조의 방제 로봇 또는 방제 장비가 개발되고 있는 실정이다.Therefore, a new method or device for solving these problems is required, and control robots or control equipment having various structures are being developed.
이러한 방제 로봇 또는 방제 장비는 그 무게가 인력만으로 옮기기에는 어려운 경우가 많으므로, 진수/회수(진회수)만을 위한 별도의 장비가 필요하게 된다.Since these control robots or control equipment are often difficult to move only by manpower, separate equipment is required for launching / recovering (recovery) only.
도 1a 및 도 1b는 지게차 구조의 크레인 장치를 나타낸다.1A and 1B show a crane device of a forklift structure.
도 1a를 참조하면, 만약 지게차와 같은 구조의 진회수 시스템을 이용하여 방제 장치를 진수/회수(진회수)한다면, 진회수 장치의 상하 가이드가 길어짐에 따라 구동 영역 제한이 생길 것이며, 상하 가이드의 전체 부분이 구동 영역이므로, 전 구간에 윤활이 되어야 하고, 국소 부분의 휨이 발생했을 때에, 상하 가이드의 양끝단으로 갈수록 단차가 심화되어 구동 영역에 제한이 될 수 있는 단점이 있다.Referring to FIG. 1A, if the control device is launched/recovered (recovered) by using a recovery system having the same structure as a forklift, as the upper and lower guides of the recovery device become longer, the driving area will be limited, and the upper and lower guides Since the entire area is the drive area, the entire area must be lubricated, and when bending of the local portion occurs, the step difference intensifies toward both ends of the upper and lower guides, which may limit the drive area.
또한, 도 1b를 참조하면, 랜딩 목표 지점과의 높이 차이만큼 가이드가 길어야 하므로 진회수 시스템의 크기가 커지는 단점이 있다. 그리고, 회수시 기체(방제 장치)의 자세 불안정성 때문에 케이스 사용이 강제되는 불편함이 있다.Also, referring to FIG. 1B , since the guide must be as long as the height difference from the landing target point, the size of the recovery system increases. In addition, there is an inconvenience in that the use of the case is forced due to the posture instability of the gas (control device) during recovery.
항만 또는 물가 근처에서 발생하는 해양오염 사고 발생시 방제 로봇 또는 방제 장비를 투입하려면 대형 크레인 또는 인력이 투입되어야 하는 문제가 있다. 사고 발생지역이 다양함에 따라 중장비 투입이 어려운 경우도 있으며 이러할 경우 인력의 투입이 불가피해져 사고환경 내 작업자의 사고위험 노출이 커지게 된다.In the event of a marine pollution accident occurring near a port or waterfront, there is a problem in that large cranes or manpower are required to input control robots or control equipment. Depending on the variety of accident areas, it is sometimes difficult to insert heavy equipment.
기존의 유압 구동식 유회수기 헤더부는 자항식 기능이 존재하지 않아 지역 이동시 크레인을 이동시켜야 하는 불편함이 존재한다. 이를 보완하고자 전기 구동식 유회수기 헤더부가 개발되고 있으며, 이는 자항식 기능이 탑재되어 크레인을 이동시키지 않아도 원하는 지역까지 이동 가능하지만, 유회수기 헤더부를 바다에 투입 및 회수시키기 위해서는 여전히 중장비 크레인을 이용해야 하며, 고리가 유회수기 헤더부에 지속적으로 연결이 되어 있어야 하는 문제점이 발생한다. 만약 주행시 크레인으로 인한 유회수기 헤더부의 이동 제한을 없애기 위해 고리를 풀게 되면, 해양에서 작업 완료 후 회수할 때 고리를 다시 걸기 위해 인력이 투입되어야 하는 불편함이 존재한다.The existing hydraulically driven skimmer header does not have a self-navigation function, so there is an inconvenience of having to move a crane when moving to an area. To compensate for this, an electrically driven skimmer header is being developed, which is equipped with a self-propelled function and can be moved to the desired area without moving a crane, but a heavy crane is still required to put and retrieve the skimmer header into the sea. However, there is a problem that the ring must be continuously connected to the skimmer header part. If the ring is released to remove the movement restriction of the skimmer header part due to the crane during driving, there is inconvenience that manpower must be put in to reattach the ring when it is retrieved after completion of work in the sea.

도 2는 크레인 구조의 진회수 시스템이 방제 장치에 연결된 것을 개략적으로 나타낸다. Figure 2 schematically shows that the recovery system of the crane structure is connected to the control device.
배경 기술부에서 언급한 바와 같이, 지게차 구조의 진회수(진수 및 회수) 시스템을 적용하는 데에는 무리가 있다. 이에 대하여, 도 2는, 크레인 구조의 진회수 시스템을, 도 3~도 10에서 설명된 수면 부유층 제거 장치(방제 로봇 또는 방제 장치라고도 함)에 대해 적용하는 예시를 나타낸다. As mentioned in the background description section, it is difficult to apply the recovery (launch and recovery) system of the forklift structure. On the other hand, FIG. 2 shows an example of applying the crane-structured recovery system to the surface floating layer removal device (also referred to as a control robot or a control device) described in FIGS. 3 to 10 .
도 2에서 보듯이 크레인 구조의 진회수 시스템(100)(이하, 크레인 장치라고도 함)은 가로 바(HB)와 상하 바(VB)를 포함한다. 가로 바(HB)는 반드시 수평 방향으로만 연장될 필요는 없고, 다소 경사지거나 또는 경사각이 변하도록 움직일 수 있다. 그리고 가로 바(HB)로부터 케이블(C)이 연장되어 그 하방의 방제 장치(10) 또는 방제 로봇에 연결된다. 이 방제 장치(10) 또는 방제 로봇은, 일예로, 도 3~10에서 상세히 설명할 선체(10)(수면 부유층 제거 장치)에 해당한다.As shown in FIG. 2, the crane structure recovery system 100 (hereinafter, also referred to as a crane device) includes a horizontal bar HB and an upper and lower bar VB. The horizontal bar HB does not necessarily extend only in the horizontal direction, and may be slightly inclined or moved such that the angle of inclination changes. And the cable (C) is extended from the horizontal bar (HB) is connected to the control device 10 or the control robot below it. This control device 10 or control robot corresponds to, for example, the hull 10 (water surface floating layer removal device) to be described in detail in FIGS. 3 to 10 .
이하, 방제 장치(10)(수면 부유층 제거 장치)의 상세에 대해 도 3~10, 도 24~30 등을 통해 설명한다.Hereinafter, details of the control device 10 (water surface layer removal device) will be described with reference to FIGS. 3 to 10 and FIGS. 24 to 30.
그리고, 이 방제 장치(10)를 들어올리는 전자석 크레인 장치(100)의 상세에 대해 도 11~23 등을 통해 설명한다.And the details of the electromagnetic crane device 100 which lifts this control device 10 are demonstrated through FIGS. 11-23 grade|etc.,.
도 3은 본 발명의 방제 장치의 일실시예의 장치를 위에서 비스듬히 본 사시도이다.Figure 3 is a perspective view obliquely viewed from above the device of one embodiment of the control device of the present invention.
본 발명에 따르는 수면 부유층 제거 장치에서 이동가능한 선체(10) 의 전면에는 오염수 유입부(20; 오염수 회수부)가 배치된다. 오염수 유입부(20)보다 뒤에는 유입된 오염수가 저장되는 저장부(40)가 존재한다. 선체(10)의 오염수 유입부(20)와 저장부(40)의 내부는 연결되어 있다.In the floating surface layer removal device according to the present invention, a contaminated water inlet (20; contaminated water recovery unit) is disposed on the front of the movable hull (10). Behind the contaminated water inlet 20 is a storage unit 40 in which the introduced contaminated water is stored. The contaminated water inlet 20 of the hull 10 and the inside of the storage unit 40 are connected.
도면 부호 10은 경우에 따라 방제 장치(10), 수면 부유층 제거 장치(10), 선체(10)를 의미하며, 이들은 거의 동일한 의미를 갖는다. 장치 자체를 설명할 때에는 수면 부유층 제거 장치(10)나 선체(10)라는 표현을 주로 사용하였고, 크레인에 의해 들어올려지는 대상으로서는 방제 장치(10)라는 표현을 주로 사용하였으나, 의미상 큰 차이는 없다. Reference numeral 10 denotes a control device 10, a surface floating layer removal device 10, and a hull 10 in some cases, which have almost the same meaning. When explaining the device itself, the expression of the floating layer removal device 10 or the hull 10 was mainly used, and the expression of the control device 10 was mainly used as the object to be lifted by the crane, but a significant difference in meaning does not exist.
션체(10)가 수면에 부유하는 상태에서 수면은 유입구(21)의 높이 범위 내에 있게 되어 선체(10)의 전진에 따라 오염수가 유입될 수 있게 되고 이러한 유입구(21)에는 오염수에 부유할 수 있는 큰 크기의 고형물의 유입을 막기 위해 여과 수단(22)이 포함된다.In a state in which the sean body 10 is floating on the water surface, the water surface is within the height range of the inlet 21, so that contaminated water can flow in as the hull 10 advances, and this inlet 21 can float in the contaminated water. A filtering means 22 is included to prevent the ingress of oversized solids.
도 4는 본 발명의 방제 장치의 일실시예의 장치를 아래에서 비스듬히 본 사시도이다.Figure 4 is a perspective view of the device of one embodiment of the control device of the present invention viewed obliquely from below.
임펠러(30-1, 30-2)는 장치의 선체(10)를 전후로 이동시키기 위한 수단이다. 2개가 도시되어 있으나, 그 갯수는 필요에 따라 조정 가능하다.The impellers 30-1 and 30-2 are means for moving the hull 10 of the device back and forth. Although two are shown, the number can be adjusted as needed.
임펠러(30-3, 30-4)는 장치의 선체(10)를 좌우로 이동시키기 위한 수단이다. 이 또한, 2개가 도시되어 있으나, 그 갯수는 필요에 따라 조정 가능하다.The impellers 30-3 and 30-4 are means for moving the hull 10 of the device left and right. Also, although two are shown, the number can be adjusted as needed.
배출구(50; 배출부)는, 유입된 오염수 중에서 기름이 분리되고 남은 물이 배출되는 부분이다. 도 4에서는 배출구(50)가 선체(10)의 하부에 있으나, 필요에 따라서는 뒷면에 배치될 수도 있고, 뒷면의 하단에 배치될 수도 있고, 하면의 뒷부분에 배치될 수도 있다.The outlet 50 (discharge unit) is a portion through which oil is separated from the introduced contaminated water and remaining water is discharged. In FIG. 4, the discharge port 50 is located at the lower part of the hull 10, but may be disposed at the rear side, at the bottom of the rear side, or at the rear side of the lower surface, if necessary.
도 5는 본 발명의 방제 장치의 일실시예의 장치를 전면에서 본 것이다.Figure 5 is a front view of the device of one embodiment of the control device of the present invention.
전면에 여과 수단(22)이 보이고 그 뒤에 임펠러(31)가 보인다. 임펠러(31)는 그 전체면이 보이지는 않고 윗부분은 물튀김 방지막(32)으로 약간 가려져 있다.The filtering means 22 is visible in the front and the impeller 31 behind it. The entire surface of the impeller 31 is not visible, and the upper part is slightly covered with an anti-splash film 32.
그리고, 아래에는 전술한 전진 및 후진용의 임펠러(30-1, 30-2)가 도시되어 있다.And, below, the aforementioned forward and backward impellers 30-1 and 30-2 are shown.
도 6은 본 발명의 방제 장치의 일실시예의 장치를 후면에서 본 것이다.Figure 6 is a rear view of the device of one embodiment of the control device of the present invention.
여기에서도, 도면의 아래에, 전술한 전진 및 후진용의 임펠러(30-1, 30-2)가 도시되어 있다.Also here, below the drawing, the aforementioned impellers 30-1 and 30-2 for forward and backward movement are shown.
도 7은 본 발명의 방제 장치의 일실시예의 장치를 위에서 본 것이다.Figure 7 is a top view of the device of one embodiment of the control device of the present invention.
도면의 우측에 오염수 유입부(20; 오염수 회수부)가 보이며, 위에서 본 것이어서 여과 수단(22)이나, 유입구(21), 임펠러(31) 등의 구조물은 잘 보이지 않는다.The contaminated water inlet 20 (contaminated water recovery unit) is visible on the right side of the drawing, and since it is viewed from above, structures such as the filtering means 22, the inlet 21, and the impeller 31 are hard to see.
그리고, 저장부(40)가 도시되어 있는데, 저장부(40)의 양쪽(선체의 좌우) 외벽은 부력을 제공하는 부력체를 포함할 수 있다. 부력은 저장부(40)의 좌우측에서 제공할 수도 있고, 저장부(40)의 하부측에서 제공할 수도 있다. 저장부(40)의 좌우측 및 하부측에서 모두 약간씩의 부력을 제공하는 것이 바람직할 것이다.In addition, the storage unit 40 is shown, and both outer walls (left and right of the hull) of the storage unit 40 may include buoyancy bodies that provide buoyancy. Buoyancy may be provided from the left and right sides of the storage unit 40 or may be provided from the lower side of the storage unit 40 . It would be desirable to provide some buoyancy on both the left and right sides and the lower side of the reservoir 40.
부력의 정도는 임펠러(31)가 절반 정도 잠기게 하는 것이 적당하다. 절반이 정확히 50%를 의미하는 것은 아니고, 40~60% 정도일 수 있다. 때에 따라서는 30~70% 정도 잠길 수도 있다. 그리하여, 물에 반쯤 잠긴 임펠러(31)의 작용으로 오염수가 적절히 선체(10) 내부의 저장부(40) 쪽으로 이동한다.As for the degree of buoyancy, it is appropriate for the impeller 31 to be half submerged. Half doesn't mean exactly 50%, it could be 40-60%. In some cases, it may be 30-70% submerged. Thus, the contaminated water appropriately moves toward the storage unit 40 inside the hull 10 due to the action of the impeller 31 half submerged in water.
물론, 선체의 전후 좌우 이동을 위한 추진력을 발휘하는 임펠러(30-1, 30-2, 30-3, 30-4)는 전부 물에 잠겨 있다. 유입부(20) 근방에 배치된 유입용의 임펠러(31)만이 대략 수면에 절반 정도 잠기는 것이다.Of course, all of the impellers 30-1, 30-2, 30-3, and 30-4 that exert propulsive force for forward and backward movement of the hull are submerged in water. Only the inlet impeller 31 disposed near the inlet 20 is submerged in about half of the water surface.
도 8은 본 발명의 방제 장치의 일실시예의 장치를 아래에서 본 것이다.Figure 8 is a bottom view of the device of one embodiment of the control device of the present invention.
오염수 유입부(20; 오염수 회수부)가 도면의 우측에 보이며, 임펠러(30-1, 30-2, 30-3, 30-4)를 확인할 수 있다.The contaminated water inlet 20 (contaminated water recovery unit) is shown on the right side of the drawing, and impellers 30-1, 30-2, 30-3, and 30-4 can be confirmed.
도 9는 본 발명의 방제 장치의 일실시예의 장치를 우측에서 본 것이다.Figure 9 is a view from the right side of the device of one embodiment of the control device of the present invention.
오염수 유입부(20; 오염수 회수부)가 도면의 우측에 보이며, 저장부(40)의 측벽, 임펠러(30-2, 30-3, 30-4)를 확인할 수 있다.The contaminated water inlet 20 (contaminated water recovery unit) is shown on the right side of the drawing, and the sidewall of the storage unit 40 and the impellers 30-2, 30-3, and 30-4 can be confirmed.
도 10은 본 발명의 방제 장치의 일실시예의 장치를 좌측에서 본 것이다.Figure 10 is a view from the left side of the device of one embodiment of the control device of the present invention.
오염수 유입부(20; 오염수 회수부)가 도면의 좌측에 보이며, 저장부(40)의 측벽, 임펠러(30-1, 30-3, 30-4)를 확인할 수 있다.The contaminated water inlet 20 (contaminated water recovery unit) is shown on the left side of the drawing, and the sidewall of the storage unit 40 and the impellers 30-1, 30-3, and 30-4 can be confirmed.
도 11a~도 11c는 도 2에 도시된 케이블(C)과 방제 장치(10)를 연결하기 위해 전자석(EM)(electromagnetic)을 이용하는 예를 나타낸다.11a to 11c show an example of using an electromagnet (EM) to connect the cable (C) and the control device 10 shown in FIG.
즉, 도 2의 케이블(C)의 하단에는 고리에 걸린 도 11a의 전자석(EM)이 존재한다. 그리고, 방제 장치(10)의 선체 자체가 금속 등의 자성체로 형성되거나, 또는 방제 장치(10)의 지붕에 금속 등의 자성체가 별도로 부착되는 경우, 상기 전자석(EM)을 방제 장치(10)의 선체의 자성체(MB)(magnetic body) 부분에 접촉시켜서 방제 장치(10)를 들어올릴 수 있다. 물론 이는 전자석(EM)의 자력(磁力)이 활성화되어 켜진 상태에서의 동작이다.That is, at the lower end of the cable C of FIG. 2, there is an electromagnet EM of FIG. 11A caught on a hook. And, when the hull itself of the control device 10 is formed of a magnetic material such as metal, or a magnetic material such as metal is separately attached to the roof of the control device 10, the electromagnet EM of the control device 10 It is possible to lift the control device 10 by contacting the magnetic body (MB) part of the hull. Of course, this is an operation in a state in which the magnetic force of the electromagnet (EM) is activated and turned on.
도 11b 및 도 11c는 전자석(EM)에 자성체(MB)를 들어올린 상태를 나타내고 있다. 도 11b와 도 11c에는 방제 장치(10) 없이 자성체(MB)만 도시되어 있으나, 이는 테스트를 위한 것이며, 당해 자성체(MB)가 방제 장치(10)에 나사 등의 체결구나 용접 등을 통해, 또는 케이블/사슬 등을 통해 체결되어 있음을 이해할 수 있을 것이다. 또는 전술한 바와 같이, 선체 자체가 금속 등의 자성체인 경우도 가능하다.11b and 11c show a state in which the magnetic material MB is lifted onto the electromagnet EM. 11b and 11c, only the magnetic body (MB) is shown without the control device 10, but this is for testing, and the magnetic body (MB) is attached to the control device 10 through fasteners such as screws or welding, or It will be appreciated that they are fastened via cables/chains or the like. Alternatively, as described above, it is also possible when the hull itself is a magnetic material such as metal.
도 12a는 전자석(EM)과 자성체(MB)와 선체의 결합 관계를 나타낸다.Figure 12a shows the coupling relationship between the electromagnet (EM), the magnetic body (MB) and the hull.
방제 장치(선체(10))와 자성체(MB)는 나사나 용접 등을 통해, 또는 케이블 등을 통해 상호 고정되어 있다. 그리고 전자석(EM)은 도 2의 크레인 장치(100)의 케이블(C)에 고리 등을 통해 연결되어 있다(도 11a 참조). The control device (hull 10) and the magnetic body MB are fixed to each other through screws, welding, or the like, or through cables. And the electromagnet (EM) is connected to the cable (C) of the crane device 100 of Figure 2 through a ring or the like (see Figure 11a).
이와 같이 구성된 전자석 크레인 장치(10)를 통해 전자석(EM)이 방제 장치(10)(정확히는 방제 장치(10)와 자성체(MB)의 결합체)를 들어올릴 수 있다. Through the electromagnetic crane device 10 configured as described above, the electromagnet (EM) can lift the control device 10 (exactly, the combination of the control device 10 and the magnetic material (MB)).
도 12b는 전자석(EM)과 자성체(MB)의 접촉면의 구조를 나타낸다.Figure 12b shows the structure of the contact surface of the electromagnet (EM) and the magnetic material (MB).
도 12b의 좌측 도면에서, 방제 장치(10)의 상부에 부착된 자성체(MB)의 상면이 오목한 형상이라면, 볼록한 형상의 하면을 갖는 전자석(EM)과 결합되기 용이한 장점이 있다. 그러나, 물이 있는 곳에서 사용되는 방제 장치(10)의 특성상, 자성체(MB)의 오목한 부분에 물이 차면 전자석(EM)과 자성체(MB)의 자력(磁力)에 의한 결합이 잘 되지 않거나 결합되더라도 약해지는 등의 문제가 있을 수 있다.In the left drawing of Figure 12b, if the upper surface of the magnetic body (MB) attached to the top of the control device 10 is concave shape, there is an advantage that it is easy to combine with the electromagnet (EM) having a convex shape when the lower surface. However, due to the nature of the control device 10 used in the presence of water, when the concave part of the magnetic body (MB) is filled with water, the electromagnet (EM) and the magnetic body (MB) are not well coupled by the magnetic force (磁 力) or the combination Even if it does, there may be problems such as weakening.
따라서, 도 12b의 우측 도면처럼, 방제 장치(10)의 상부에 부착된 자성체(MB)의 상면이 볼록한 형상인 것이 바람직하다. 이 경우, 전자석(EM)의 하면은 자성체(MB)의 상면과 접하도록 오목한 형상을 가질 수 있다. Therefore, as shown in the right drawing of FIG. 12b, it is preferable that the top surface of the magnetic material (MB) attached to the top of the control device 10 has a convex shape. In this case, the lower surface of the electromagnet EM may have a concave shape to contact the upper surface of the magnetic material MB.
이는 일예이며, 자성체(MB)의 상면이 중앙에 평탄면을 가지면서 전체적으로 볼록하고 전자석(EM)의 하면도 중앙에 평탄면을 가지면서 전체적으로 볼록한 경우도 가능하다. 이 경우는 중앙의 평탄면끼리 접하여 방제 장치(10)를 들어올릴 수 있기 때문이다. 다만, 도 12b의 우측 도면처럼 자성체(MB)와 전자석(EM)의 형상이 서로 상보적인 것이 서로의 결합력 확보에 유리할 것이다.This is an example, and it is also possible that the upper surface of the magnetic material MB is generally convex with a flat surface in the center, and the lower surface of the electromagnet EM is also generally convex with a flat surface in the center. In this case, it is because the flat surfaces of the center are in contact with each other and the control device 10 can be lifted. However, as shown in the right drawing of FIG. 12B, it will be advantageous to secure mutual bonding force if the shapes of the magnetic material MB and the electromagnet EM are complementary to each other.
도 13은 본 발명의 진회수 시스템(100)의 구체적인 일예이다.13 is a specific example of the gin recovery system 100 of the present invention.
도 2에서는 진회수 시스템(100)(크레인 장치)을 대략적으로만 도시했으나, 도 13에 그 구체적인 예를 나타낸다. 도 13의 (a)는 진회수 시스템(100)이 방제 장치(10)를 수납하여 옮기고 있는 모습을 나타내며, 도 13의 (b)는 진회수 시스템(100)이 방제 장치(10)를 올리고 내릴 때의 모습을 나타낸다(단, 케이블의 도시는 생략되어 있음).In FIG. 2, the recovery system 100 (crane device) is only schematically shown, but FIG. 13 shows a specific example thereof. 13 (a) shows a state in which the dust recovery system 100 stores and moves the control device 10, and FIG. 13 (b) shows the dust recovery system 100 raising and lowering the control device 10 It shows the state at the time (however, the illustration of the cable is omitted).
도 13의 (b)에서 케이블은 도시가 생략되어 있다. 진회수 시스템(100)은 세로 바(VB), 가로 바(HB), 통합 제어 컨트롤 패널(CP), 윈치(W), 지지 다리(100-1, 100-2, 100-3, 100-4, 100-5)를 포함한다. In (b) of FIG. 13, the cable is omitted from the drawing. The recovery system 100 includes a vertical bar (VB), a horizontal bar (HB), an integrated control control panel (CP), a winch (W), and support legs (100-1, 100-2, 100-3, 100-4 , 100-5).
지지 다리(100-1 내지 100-5)는 넓은 의미로는 지지대라고 부를 수도 있다.The support legs 100-1 to 100-5 may be referred to as supports in a broad sense.
도 13의 (b)를 참조하면, 가로 바(HB)는 그 길이가 여러 단계로 조절될 수 있다.Referring to (b) of FIG. 13 , the length of the horizontal bar HB may be adjusted in several stages.
도 13의 (b)에서 지지 다리(100-1 내지 100-5)는 땅바닥 또는 모선의 바닥을 딛고 있으며, 방제 장치(10)는 물에 진수(launch)되거나 물로부터 회수(recovery)되려는 상황이다. 이때 지지 다리(100-3, 100-4)는 그 하단부가 아래로 연장되어 진회수 시스템(100)의 무게를 받치며, 또한 지지 다리(100-3, 100-4)가 무게를 받칠 때에는 지지 다리(100-1, 100-2, 100-5)의 바퀴에 의해서 자유롭게 움직이는 것이 제한된다. 지지 다리(100-3, 100-4)는 필수적인 요소는 아니다. 다만, 지지대는 적어도 3개소(예컨대, 100-1, 100-2, 100-5)에서 진회수 시스템(100)을 받치는 것이 바람직하다.In (b) of FIG. 13, the support legs 100-1 to 100-5 stand on the ground or the bottom of the mother ship, and the control device 10 is launched into the water or is about to be recovered from the water. . At this time, the lower ends of the support legs 100-3 and 100-4 extend downward to support the weight of the recovery system 100, and when the support legs 100-3 and 100-4 support the weight, Free movement is restricted by the wheels of the legs 100-1, 100-2 and 100-5. Support legs 100-3 and 100-4 are not essential elements. However, it is preferable that the support supports the dust recovery system 100 at at least three locations (eg, 100-1, 100-2, and 100-5).
도 13의 (a)에서는 진회수 시스템(100)에 방제 장치(10)가 결합되어 이동하는 상태를 나타낸다. 결합 상태가 자세히 도시되어 있지는 않으나, 방제 장치(10)의 측면 및/또는 하단이 진회수 시스템(100)에 체결되거나 걸침으로써 결합될 수 있다. 즉, 방제 장치(10)에 오목 또는 볼록한 구조체가 있어서 이 구조체가 진회수 시스템의 지지 다리(100-1)와 지지 다리(100-2) 사이의 부분(즉, 수납부)에 걸리도록 하는 것이 바람직하다. 오목 또는 볼록한 구조체 및 걸리는 부분은 도시가 생략되어 있으나, 방제 장치(10)의 하중을 견딜 수 있다면 어떠한 구조라도 가능하다. 또는 방제 장치(10)의 상단부에 위치한 바(10-B)에 진회수 시스템(100)이 결합되는 것도 가능하다.13 (a) shows a state in which the control device 10 is coupled to the dust recovery system 100 and moves. Although the coupling state is not shown in detail, the side and / or bottom of the control device 10 may be coupled by being fastened to or strung on the recovery system 100. That is, there is a concave or convex structure in the control device 10 so that this structure is caught in the portion between the support leg 100-1 and the support leg 100-2 of the recovery system (ie, the receiving part). desirable. Concave or convex structures and hooking parts are not shown, but any structure is possible as long as it can withstand the load of the control device 10. Alternatively, it is also possible that the dust recovery system 100 is coupled to the bar 10-B located at the upper end of the control device 10.
이러한 구조를 통해서 진회수 시스템(100)은 단지 리프트로만 기능하는 것이 아니라, 방제 장치(10)를 이동시키는 용도로도 사용될 수 있다. 방제 장치를 이동시키는 도 13의 (a)와 같은 형태에서는 지지 다리(100-3, 1004)의 하단부가 바퀴의 바닥보다 더 위로 올라가 있고, 따라서 바퀴만으로 용이하게 이동이 가능하다.Through this structure, the recovery system 100 does not function only as a lift, but can also be used for moving the control device 10. In the form of FIG. 13 (a) for moving the control device, the lower end of the support leg (100-3, 1004) is higher than the bottom of the wheel, and therefore can be easily moved only with the wheel.
바퀴로 이동하는 것은 모터를 통해서도 가능하고, 사람이 진회수 시스템(100)을 수동으로 미는 형태도 가능하다.Movement by wheels is also possible through a motor, and a form in which a person manually pushes the recovery system 100 is also possible.
도 14는 도 13에 나타난 구조를 더욱 상세히 나타낸 도면이다.14 is a view showing the structure shown in FIG. 13 in more detail.
도 14의 (a)에서 세로 바(VB)와 가로 바(HB)의 사이에는 관절이 있으며, 이 관절의 움직임에 따라서 가로 바(HB)의 지면에 대한 각도가 변할 수 있다. 그리고, 가로 바(HB)의 일단에는 윈치(W)가 설치되어, 가로 바(HB)를 따라 케이블이 가로 바(HB)의 타단까지 연장되고, 당해 타단으로부터는 케이블이 아래로 연장되어 전자석(EM)에 연결된다.In (a) of FIG. 14, there is a joint between the vertical bar (VB) and the horizontal bar (HB), and the angle of the horizontal bar (HB) with respect to the ground may be changed according to the movement of the joint. In addition, a winch (W) is installed at one end of the horizontal bar (HB), the cable extends along the horizontal bar (HB) to the other end of the horizontal bar (HB), and the cable extends downward from the other end to the electromagnet ( EM) is connected.
세로 바(VB)와 가로 바(HB)가 만나는 관절 부근에는, 예컨대 디스플레이 화면을 갖는 통합 제어 컨트롤 패널(CP)이 적용되어 있다. 이 컨트롤 패널(CP)을 통해 움직임(가로 바(HB)의 각도 조절, 가로 바(HB)의 길이 조절, 방제 장치(10)의 수납 여부, 윈치의 케이블 와인딩, 전자석의 온/오프, 가로 등)을 모두 제어할 수 있도록 하는 것이 바람직하다. 방제 장치(10)의 수납 여부란, 도 13의 (a)와 같이 방제 장치(10)를 수납하여 이동하는 모드인지, 도 13의 (b)와 같이 방제 장치(10)를 진/회수하는 모드인지를 결정하는 것을 말하며, 케이블(C)과 전자석(EM)을 이용하여 방제 장치(10)를 수납부(제1 지지 다리(100-1)와 제2 지지 다리(100-2)의 사이)에 위치시키고 어딘가에 걸리게 하여 고정시키는 등의 방식을 이용할 수 있다. 또는 컨트롤 패널(CP)을 통해 진회수 시스템(100)의 바퀴를 움직여서 미세 조정으로 진회수 시스템(100)의 위치를 지정하는 것도 가능하다. 즉, 바퀴는 사람이 수동으로 밀어서 움직이는 것도 가능하고, 컨트롤 패널(CP)을 통해 움직이는 것도 가능하다. 윈치(W)의 모터나 바퀴에 연동된 모터는 감속기가 적용된 것을 사용하여 작은 전력으로도 구동이 가능하도록 하는 것이 바람직하다. 예컨대, 윈치(W)가 24V로 구동되므로 전자석(EM), 컨트롤 패널(CP), 구동 모터가 모두 24V로 구동되면 진회수 시스템(100) 전체의 효율성이 더 좋아진다. An integrated control panel CP having, for example, a display screen is applied near the joint where the vertical bar VB and the horizontal bar HB meet. Through this control panel (CP), movements (angle adjustment of the horizontal bar (HB), length adjustment of the horizontal bar (HB), whether or not the control device 10 is accommodated, cable winding of the winch, on/off of the electromagnet, horizontal, etc. ) is desirable to be able to control all of them. Whether the control device 10 is accommodated is a mode in which the control device 10 is stored and moved as shown in FIG. 13 (a), or a mode in which the control device 10 is advanced / retrieved as shown in FIG. 13 (b) It refers to determining the recognition, using the cable (C) and the electromagnet (EM) to control the control device 10 in the receiving part (between the first support leg 100-1 and the second support leg 100-2) You can use a method such as placing it on and fixing it by hanging it somewhere. Alternatively, it is possible to designate the position of the ash recovery system 100 through fine adjustment by moving the wheels of the ash recovery system 100 through the control panel CP. That is, the wheel can be moved manually by a person pushing it, or it can be moved through the control panel CP. It is preferable that the motor of the winch (W) or the motor linked to the wheel can be driven with a small amount of power by using a gearbox applied thereto. For example, since the winch W is driven by 24V, the overall efficiency of the recovery system 100 becomes better when the electromagnet EM, the control panel CP, and the driving motor are all driven by 24V.
도 15a 및 도 15b는 본 발명의 진회수 시스템의 다른 실시예를 나타낸다.15A and 15B show another embodiment of the recovery system of the present invention.
이는 도 13에 나타난 실시예와는 다소 상이하다. 즉, 도 13에 나타난 지지 다리(100-3, 100-4)가 생략되어 있어서 더욱 간단한 구조를 통해 유사한 효과를 얻을 수 있다. This is somewhat different from the embodiment shown in FIG. 13 . That is, since the support legs 100-3 and 100-4 shown in FIG. 13 are omitted, a similar effect can be obtained through a simpler structure.
이 경우, 지지 다리(100-3, 100-4)의 부재로 인하여 지면(또는 모선 바닥)에의 고정력이 다소 약해질 수 있는 점, 방제 장치(10)를 수납한 채로 이동하기 힘들다는 점 등의 단점이 존재하나, 구조가 간단하여 작업과 제조가 용이해진다는 장점이 있다.In this case, due to the absence of the support legs 100-3 and 100-4, the fixing force to the ground (or the bottom of the busbar) may be somewhat weakened, and it is difficult to move while the control device 10 is housed. Although there are disadvantages, there is an advantage that the structure is simple and the work and manufacturing are easy.
도 16a 내지 도 16c는 본 발명의 진회수 시스템(100)의 일실시예에 대한 소형 모델을 나타낸다.16A to 16C show a miniature model of one embodiment of the ash recovery system 100 of the present invention.
도 16a는 도 15a 및 도 15b에 도시된 진회수 시스템(100)의 모델을 나타낸다.16A shows a model of the recovery system 100 shown in FIGS. 15A and 15B.
도 16b 및 도 16c는 도 15a의 진회수 시스템이 실제로 방제 장치(10)(의 모델)을 들어올리는 모습을 나타낸다.16B and 16C show how the dust collection system of FIG. 15A actually lifts (a model of) the control device 10.
도 16b, 도 16c를 참조하면, 전자석(EM)에 자력(磁力)으로 부착될 자성체(MB)가 방제 장치(10)에 결합되는 방식의 다른 일예를 볼 수 있다.Referring to Figures 16b, 16c, you can see another example of the way the magnetic material (MB) to be attached by magnetic force to the electromagnet (EM) coupled to the control device (10).
도 16b에서 보는 바와 같이, 전자석(EM)에 자력으로 부착되는 자성체(MB)는 반드시 방제 장치(10)의 상면(즉, 지붕면)에 면접촉되어 있을 필요는 없다. 즉, 대략 판상(다소 오목이나 볼록이 있어도 무방하며 완전히 판상이라도 무방함)의 자성체(MB)가 복수개의 별도의 케이블(C2)을 통해 방제 장치(10)와 결합되어 있는 것을 볼 수 있다. 이렇게 되면, 방제 장치(10)의 지붕면이 반드시 금속일 필요도 없고 금속이 아니라도 반드시 딱딱한 물체일 필요도 없다. 예컨대, 방제 장치(10)의 지붕면은 두꺼운 비닐 재질일 수도 있고 4개의 휠 수 있는 케이블(C2)이나 사슬 등이 방제 장치(10)의 4개의 모서리에 연결되어 있을 수 있다. 이 경우, 자성체(MB)는 비닐 재질의 지붕면에 놓여 있다가, 전자석(EM)이 자성체(MB)에 자력으로 부착되면서 들어올리면 전자석(EM)과 자성체(MB)의 결합체가 들어올려지면서 자성체(MB)와 지붕면 사이에 공간이 생기고, 케이블(사슬 형태를 포함함)이 팽팽해지면서 방제 장치(10) 전체가 들어올려질 것이다. 이 예에서는 별도의 케이블(C2)이 4개이지만, 3개 이상이면 충분할 것이다.As shown in Figure 16b, the magnetic material (MB) magnetically attached to the electromagnet (EM) does not necessarily have to be in surface contact with the upper surface (ie, roof surface) of the control device (10). That is, it can be seen that the approximately plate-shaped (even if somewhat concave or convex, even if completely plate-shaped) magnetic material (MB) is coupled with the control device 10 through a plurality of separate cables (C2). In this case, the roof surface of the control device 10 does not necessarily have to be metal, and even if it is not metal, it does not necessarily have to be a hard object. For example, the roof surface of the control device 10 may be made of a thick vinyl material, and four flexible cables C2 or chains may be connected to the four corners of the control device 10. In this case, the magnetic material (MB) is placed on the roof surface made of vinyl material, and when the electromagnet (EM) is attached to the magnetic material (MB) with magnetic force and lifted, the combination of the electromagnet (EM) and the magnetic material (MB) is lifted and the magnetic material (MB) is lifted. A space is created between the (MB) and the roof surface, and the entire control device 10 will be lifted as the cable (including the chain type) is tensioned. In this example, there are four separate cables (C2), but three or more will suffice.
자성체(MB)와 케이블(또는 사슬)(C2) 사이의 연결은 고리를 이용할 수도 있으며, 케이블(또는 사슬)(C2)과 방제 장치(10) 사이의 연결에도 고리를 이용할 수도 있다. The connection between the magnetic body (MB) and the cable (or chain) (C2) may use a ring, and may also use a ring for the connection between the cable (or chain) (C2) and the control device (10).
도 17a 및 도 17b는 다른 실시예의 자성체 부착 파트를 나타낸다.17A and 17B show a magnetic body attachment part of another embodiment.
도 16b, 도 16c에서는 자성체(MB)가 케이블(C2)이나 사슬을 통해 방제 장치(10)에 부착되어 있었으나, 도 17a, 도 17b에서는 자성체(MB)의 하면으로부터 방사형으로 수평 연장되다가 하부측으로 휘어 연장되는 복수의 고정 부재(FM)가 나타나 있다.16b and 16c, the magnetic material (MB) was attached to the control device 10 through the cable (C2) or chain, but in FIGS. A plurality of extending fixing members FM are shown.
도 17a에서는 마무리가 덜 된 상태로서 자성체(MB)의 측면이 대략 수직이지만, 도 17b에서는 그 측면에 경사면을 갖는 부재를 부착함으로써 자성체(MB)가 전체적으로 위로 볼록한 상태가 되도록 한다(도 12b의 우측 도면의 자성체(MB)와 같이). 도 17b에 보이는 자성체(MB)의 가운데면은 평평하고, 그 둘레부에 검은색의 경사면 부재가 부착되어, 전체적으로 위로 볼록한 상태이며, 이는 도 12b의 우측에서 도시한 것에 해당한다.In FIG. 17A, the side surface of the magnetic body MB is substantially vertical in an unfinished state, but in FIG. 17B, a member having an inclined surface is attached to the side surface so that the magnetic body MB is convex upward as a whole (right side of FIG. 12B). as in the magnetic body (MB) in the drawing). The central surface of the magnetic material MB shown in FIG. 17B is flat, and a black inclined plane member is attached to its circumference, so that it is convex upward as a whole, which corresponds to the one shown on the right side of FIG. 12B.
도 18은 다른 실시예의 전자석(EM) 및 자성체(MB)를 나타낸다.18 shows an electromagnet (EM) and a magnetic body (MB) of another embodiment.
도 17b에 나타난 자성체(MB)는 도 12b의 우측 도면과 같은 형태였으나, 도 18에 나타난 자성체(MB)는 상면이 오목한 형태이어서 일견하여서는 도 12b의 좌측 도면의 자성체(MB)와 유사한 형태로 보일 수 있다. 그러나, 도 18에 나타난 실시예에서는 자성체(MB)에 배수를 위한 홈(Gr)이 복수 형성되어 있는 것을 볼 수 있다. 따라서, 비록 상면이 오목한 형태라고 해도 그 오목부에 물이 고이지 않는다. 이는 일체형 구조일 수도 있고, 도 17b에 도시된 자성체(MB)의 상부에 추가 구조물을 부가하여 도 18에 도시된 바와 같은 구조의 자성체(MB)를 마련할 수도 있다.The magnetic material MB shown in FIG. 17B has the same shape as the right drawing of FIG. 12B, but the magnetic material MB shown in FIG. 18 has a concave top surface, so it may look similar to the magnetic material MB shown in the left drawing of FIG. 12B at first glance. can However, in the embodiment shown in FIG. 18 , it can be seen that a plurality of grooves Gr for drainage are formed in the magnetic material MB. Therefore, even if the upper surface is concave, water does not accumulate in the concave portion. This may be an integral structure, or an additional structure may be added to the top of the magnetic body MB shown in FIG. 17B to provide a magnetic body MB having a structure as shown in FIG. 18 .
한편, 자성체(MB)가 도 18과 같은 구조이면, 전자석(EM)은 그의 도 18에 나타난 바와 같이 아래로 볼록한 구조인 것이 바람직하다. 자성체(MB)의 오목부에 결합하여 정확하고 안정적인 리프팅을 행하기 위함이다. On the other hand, if the magnetic material MB has a structure as shown in FIG. 18, the electromagnet EM preferably has a downward convex structure as shown in FIG. 18 thereof. This is to perform accurate and stable lifting by combining with the concave part of the magnetic material (MB).
특히, 전자석(EM)은 모듈화할 수도 있다. 이 경우의 이점을 도 19 등을 이용하여 설명한다.In particular, the electromagnet EM may be modularized. Advantages of this case are explained using FIG. 19 and the like.
도 19는 모듈화된 전자석(EM)을 나타낸다.19 shows a modularized electromagnet (EM).
도 18 및 도 19에 도시된 모듈화된 전자석(EM)은 아래로 볼록하게 도시되어 있으나, 볼록/오목의 여부는 필요에 따라 정할 수 있다. 도 18과 도 19에 도시된 전자석(EM)은, 도 11a에 나타난 것과는 달리, 모듈화되어 있는데, 예컨대, 배터리와 인버터와 컨트롤 회로 등을 통합하여 모듈화한 것이다. 즉, 전자석(EM)과 이를 구동하기 위한 전장부를 간소화하여 모듈화하는 것인데, 이를 통해서 진회수 시스템(100)(크레인 장치)에서 전자석(EM)을 쉽게 활용할 수 있게 된다.The modularized electromagnets EM shown in FIGS. 18 and 19 are convex downward, but whether they are convex/concave may be determined as needed. The electromagnets EM shown in FIGS. 18 and 19 are modularized, unlike those shown in FIG. 11A, and are modularized by integrating, for example, a battery, an inverter, and a control circuit. That is, the electromagnet (EM) and the electrical part for driving it are simplified and modularized, and through this, the electromagnet (EM) can be easily utilized in the recovery system 100 (crane device).
본 발명의 모듈화 전자석에 있어서, 전자석은 진회수 장비(100)의 일부분이며, 크레인과 통합되어 사용된다. 기존 크레인 부에 배터리와 컨트롤 박스, 인버터 등을 거치하고 유선으로 전자석에 선을 연결해서 사용하는 방식 대신에, 전자석 모듈화를 통해 외부 케이블 및 컨트롤 박스 없이도 전자석이 독립적으로 가동되게 하는 것이다.In the modular electromagnet of the present invention, the electromagnet is a part of the dust recovery equipment 100 and is used in combination with a crane. Instead of installing a battery, control box, inverter, etc. in the existing crane and connecting wires to the electromagnet with wires, the electromagnet is modularized so that the electromagnet can operate independently without external cables and control boxes.
도 20a 및 도 20b는 무게의 관점에서 모듈화를 설명한다.20a and 20b illustrate modularization in terms of weight.
배터리, 인버터, 컨트롤부를 별도로 설치하면, 예컨대, 도 20a에서 나타난 바와 같이, 배터리가 21.32kg, 인버터가 3.80kg, 컨트롤부가 3.48kg으로 총무게가 28.6kg이었다. 이는 전자석 자체의 무게는 포함하지 않은 것이다. 이를 모듈화하면 도 19b와 같이 7.84kg이 된다(측정된 22.34kg에서 전자석 자체의 무게 14.5kg을 뺀 것). When the battery, the inverter, and the control unit are separately installed, for example, as shown in FIG. 20A, the battery weighs 21.32 kg, the inverter weighs 3.80 kg, and the control unit weighs 3.48 kg, resulting in a total weight of 28.6 kg. This does not include the weight of the electromagnet itself. If this is modularized, it becomes 7.84 kg as shown in FIG. 19b (14.5 kg of the weight of the electromagnet itself is subtracted from the measured 22.34 kg).
도 21a 및 도 21b는 비용의 관점에서 모듈화를 설명한다.21A and 21B illustrate modularization in terms of cost.
물론 어떤 사양으로 만드는지에 따라 다르지만 일예로 소요되는 비용은 아래와 같다.Of course, it depends on what specifications are made, but the cost required as an example is as follows.
예컨대, 도 21a와 같이 리튬이온팩, 인버터, 잔류자기 제거용 컨트롤러를 별도로 구매하면, 각각 220만원, 33만6600원, 98만4500원이 소요되어 총 352만1100원이 소요된다(전자석은 제외).For example, if a lithium ion pack, an inverter, and a controller for removing residual magnetism are separately purchased as shown in FIG. 21A, they cost 2.2 million won, 336,600 won, and 984,500 won, respectively, for a total of 3,521,100 won (excluding the electromagnet). ).
이를 도 21b와 같이 통합하면, 레귤레이터 개당 5500원(×2개), BMS 개당 12000원(×3개), 18650 셀당 2850원(×36개)로 총 15만9500원이 소요된다(전자석 제외).If this is integrated as shown in FIG. 21B, a total of 159,500 won is required, which is 5,500 won per regulator (x2), 12,000 won per BMS (x3), and 2,850 won per 18650 cell (x36) (excluding electromagnets). .
전자석 자체는 두 경우 모두 190만원 정도 소요된다.The electromagnet itself costs about 1.9 million won in both cases.
도 22는 전자석(EM)이 모듈화되기 전의 상태를 나타낸다.22 shows a state before the electromagnet EM is modularized.
도 23은 전자석(EM)이 모듈화된 후의 상태를 나타낸다.23 shows a state after the electromagnet EM is modularized.
도 22에서는 배터리, 제어부, 전선 등이 진회수 시스템의 하단에서부터 세로 바(VB)를 거쳐 가로 바(HB)로 이어져 있다. 또한, 도시되어 있지는 않으나, 전선은 전자석(EM)까지 이어져야 하므로 배선이 복잡해지고 사용이 불편할 수 있다.In FIG. 22 , the battery, control unit, electric wire, etc. are connected from the lower end of the recovery system to the horizontal bar HB via the vertical bar VB. In addition, although not shown, since the wire must be connected to the electromagnet EM, wiring may be complicated and use may be inconvenient.
반면에, 도 23의 모듈화된 전자석은, 도 22에서와 같은 부가 장비의 선적이 필요없고, 전자석에 케이블 연결이 필요하지 않아(무선 사용) 사용 환경 측면에서 훨씬 자유롭다. 도 23는 전자석 모듈의 상부 커버가 덮여 있지 않은 상태이며, 상부 커버를 덮으면 도 19의 우측 상부와 같은 형태가 되고, 당해 전자석 모듈은 무선으로 신호를 송수신하므로 외부로 이어지는 별도의 배선이 필요하지 않다.On the other hand, the modularized electromagnet of FIG. 23 does not require shipment of additional equipment as shown in FIG. 22 and does not require cable connection to the electromagnet (wireless use), so it is much freer in terms of the use environment. 23 is a state in which the upper cover of the electromagnet module is not covered, and when the upper cover is covered, the shape is the same as the upper right corner of FIG. .
즉, 전자석 모듈을 스마트폰과 같은 모바일 기기에서 블루투스 등의 무선 통신으로 컨트롤할 수 있게 된다. 전자석 모듈화 및 간단한 원격 구동 방식을 통해서 환경에 제약 없이 작업자 누구나 손쉽게 활용 가능하다. 컨트롤 기기는 스마트폰일 수도 있고, 다른 예로는 도 13, 도 14 등에 도시된 컨트롤 패널(CP)일 수도 있다.That is, the electromagnet module can be controlled by wireless communication such as Bluetooth in a mobile device such as a smart phone. Through electromagnet modularization and a simple remote operation method, anyone can use it easily without restrictions in the environment. The control device may be a smart phone, or may be a control panel (CP) shown in FIGS. 13 and 14 as another example.
이상, 도 2, 도 11~23을 통해 진회수 시스템(100)(크레인 장치)에 대해 상세히 설명하였다.In the above, the dust recovery system 100 (crane device) has been described in detail with reference to FIGS. 2 and 11 to 23 .
이하, 도 24~도 30에서는, 상기 진회수 시스템(100)에 의한 리프팅의 대상물인 방제 장치(10)(수면 부유층 제거 장치)에 대해서 추가 설명한다.Hereinafter, in FIGS. 24 to 30, the pest control device 10 (water surface floating layer removal device), which is an object of lifting by the ginseng recovery system 100, will be further described.
도 24a는 유입부(20) 부근의 측단면도이다.24A is a cross-sectional side view of the vicinity of the inlet 20.
도 24a에서는 임펠러(31)를 감싸고 있는 파이프(33)가 도시되어 있고, 이 파이프(33)를 통해 유입부(20)와 저장부(40)가 연결되는 것을 알 수 있다. 설명의 편의상, 여과 수단(22)의 도시는 생략되어 있다.In FIG. 24a , a pipe 33 surrounding the impeller 31 is shown, and it can be seen that the inlet 20 and the storage 40 are connected through the pipe 33 . For convenience of description, illustration of the filtering means 22 is omitted.
임펠러(31)는 오염수의 유입(회수)를 위한 구조물이며, 이는 모터(31M)와 연결되어 동작하는 것일 수 있다.The impeller 31 is a structure for inflow (recovery) of contaminated water, which may operate in connection with the motor 31M.
도 24a에 나타난 모터(31M)의 위치는 일예이며, 다른 위치도 가능하다.The position of the motor 31M shown in FIG. 24A is an example, and other positions are also possible.
임펠러(31)는, 오염수를 유입(회수)하는 것인데, 달리 말하면, 해수면에 있는 기름을 아래로 눌러 뒤로 보낸다고 설명할 수도 있다. 이 경우, 회수 시작 지점에 임펠러(31)가 가까울수록, 선체(10)의 전면부에 있는 유출유와 임펠러(31)가 더 빠르게 접촉이 가능하게 되면서 회수 속도가 향상된다.The impeller 31 is to introduce (recover) contaminated water, but in other words, it can be explained that the oil on the sea level is pushed down and sent back. In this case, the closer the impeller 31 is to the recovery start point, the faster the contact between the effluent oil and the impeller 31 on the front of the hull 10 is possible and the recovery speed is improved.
즉, 선체(10)가 전진하면서 유출유(오염수)를 회수할 때, 임펠러 하우징(33; 파이프)에서의 유입물(즉, 바닷물+유출유) 정체 현상이 발생하는 것을 억제하기 위해서, 임펠러(31) 및 임펠러 하우징(33)의 위치를 전진시키고 불필요한 전면부를 제거함으로써 정체 현상을 해소할 수 있다. 이러한 관점에서, 후술할 도 24b의 형태보다는 도 24a의 형태의 유입 효율이 더 좋을 수 있다.That is, when the hull 10 moves forward and recovers the effluent oil (contaminated water), in order to suppress the occurrence of stagnation of the inflow (ie, seawater + effluent oil) in the impeller housing 33 (pipe), the impeller 31 and the impeller housing 33 are moved forward and the unnecessary front part is removed, thereby solving the congestion phenomenon. From this point of view, the inflow efficiency of the form of FIG. 24a may be better than that of FIG. 24b, which will be described later.
도 24b는 도 24a와는 다른 실시예를 나타내는 도면이다.24B is a diagram showing an embodiment different from that of FIG. 24A.
도 24b는 유입부(20)와 저장부(40)가 파이프(33)를 통해 연결되는 것이 도시되어 있고, 큰 틀에서의 구성은 도 24a에서 설명한 바와 유사하다.FIG. 24B shows that the inlet 20 and the storage 40 are connected through a pipe 33, and the configuration in the large frame is similar to that described in FIG. 24A.
도 24b에서는 여과 수단(22)이 도시되어 있고, 도 24a와는 달리, 임펠러(31)를 작동시키는 모터(31M)가 여과 수단(22)의 위에 배치되어 있다. 이러한 모터(31M)의 위치는 무게 배분, 선체(10, 10')의 두께, 형상 등을 고려하여 변경가능하다.In FIG. 24B , the filtering means 22 is shown, and unlike FIG. 24A , a motor 31M for operating the impeller 31 is disposed above the filtering means 22 . The location of the motor 31M can be changed in consideration of weight distribution, thickness and shape of the hulls 10 and 10'.
또한, 도 24b에서 여과 수단(22)의 위치는 도 3의 것에 비하여 더욱 안쪽(선체의 뒤쪽)으로 이동해 있다. 이 또한, 무게 배분, 선체(10, 10')의 두께, 형상 등을 고려하여 변경가능하다.Also, in FIG. 24B, the position of the filtering means 22 is moved further inward (rear side of the hull) compared to that in FIG. 3. This can also be changed in consideration of weight distribution, thickness and shape of the hulls 10 and 10'.
도 24b에서 회수 시작 지점이 점선으로 나타나 있다. 이 경우, 회수 시작 지점과 임펠러(31)와의 거리가 (도 24a의 경우에 비해) 멀기 때문에, 유입 효율면에서 다소 효율이 낮을 수도 있다. In FIG. 24B, the recovery starting point is indicated by a dotted line. In this case, since the distance between the recovery start point and the impeller 31 is long (compared to the case of FIG. 24A), the inflow efficiency may be somewhat low.
반면에, 도 24a에서는 회수 시작 지점(점선)이 거의 임펠러(31) 부근이므로 회수 효율이 더 높을 수 있다. 물론, 도 24a의 도시처럼 여과 수단(22; 도 3 등 참조)을 생략하면 가장 회수 효율이 좋을 것이지만, 필요에 따라서, 도 3 등과 같이 큰 부유물을 걸러주는 여과 수단(22)을 설치하는 것이 좋을 수도 있다. 즉, 필요에 따라, 여과 수단(22)을 생략하거나, 임펠러(31)에 더 가깝게(도 3의 도시에 비해 더 가깝게) 설치하는 등의 변형이 가능할 것이다.On the other hand, in FIG. 24A, since the recovery start point (dotted line) is near the impeller 31, the recovery efficiency may be higher. Of course, if the filtering means 22 (see FIG. 3, etc.) is omitted as shown in FIG. 24A, the recovery efficiency will be the best. may be That is, modifications such as omitting the filtering unit 22 or installing it closer to the impeller 31 (closer to that shown in FIG. 3) will be possible, if necessary.
물론, 도 24a의 형태가 도 24b의 형태에 비해 오염수 유입 효율이 좋겠지만, 도 24a의 형태와 도 24b의 형태 모두 본 발명의 실시예에 포함된다.Of course, although the form of FIG. 24a has better contamination water inflow efficiency than the form of FIG. 24b, both the form of FIG. 24a and the form of FIG. 24b are included in an embodiment of the present invention.
도 25a는 도 3에 비하여 유입부(20) 부분이 더 단순화되어 도시된 도면이다.25A is a more simplified view of the inlet 20 compared to FIG. 3 .
도 25a는 도 3에 비해 여과 수단(22)이 생략되어 있는데, 임펠러(31)가 더 잘 보이도록 하기 위해 도시상으로만 생략한 것으로 이해할 수도 있고, 필요에 따라서는 실제로 여과 수단(22)을 설치하지 않음으로써 유입 효율을 높이도록 해도 무방하다. In FIG. 25A, the filtering means 22 is omitted compared to FIG. 3, and it can be understood that the impeller 31 is omitted only as a drawing in order to make it more visible, and if necessary, the filtering means 22 is actually It is okay to increase the inflow efficiency by not installing it.
도 25a에서 임펠러(31)의 앞 상단부에는 물튀김 방지막(32)이 설치되어 있다. In FIG. 25A, an anti-splashing film 32 is installed on the upper front portion of the impeller 31.
도 25b는 도 25a의 부분 확대도이다.25B is a partially enlarged view of FIG. 25A.
도면에는 나타나 있지 않으나, 수면은 임펠러(31)의 중간 정도가 되도록 선체(10)의 부력이 조정된다. 즉, 대략 임펠러(31)의 회전축 위는 물이 잠겨 있지 않고, 회전축 아래는 물에 잠겨 있는 모습이 될 것이다.Although not shown in the drawing, the buoyancy of the hull 10 is adjusted so that the surface of the water is about the middle of the impeller 31. That is, water is not submerged above the rotational axis of the impeller 31, and water is submerged below the rotational axis.
이 때, 임펠러(31)는 오염수를 유입하여 저장부(40) 쪽으로 보내는데, 수면 위쪽(즉, 임펠러의 위쪽 절반) 부근으로 유입수가 튀겨 나갈 수 있다. 이를 방지하기 위하여, 임펠러(31)가 설치된 파이프(33; 임펠러 하우징)의 입구쪽 상단 일부가 물튀김 방지막(32)으로 가려져 있다. 이러한 방지막(32)은 임펠러 하우징(33) 쪽으로 유입된 유입수가 임펠러(31)에 의해 바깥(즉, +X 방향)으로 튀겨져 나가는 것을 막아주는 역할을 한다. 이러한 동작을 통해, 유수(oil-water; 오염수)를 유입(회수)하는 효율이 높아질 수 있다.At this time, the impeller 31 introduces the contaminated water and sends it toward the storage unit 40, and the inflow water may splash out near the top of the water surface (ie, the upper half of the impeller). In order to prevent this, a part of the upper end of the inlet side of the pipe 33 (impeller housing) in which the impeller 31 is installed is covered with an anti-splashing film 32. This prevention film 32 serves to prevent the inflow water introduced into the impeller housing 33 from being splashed outward (ie, in the +X direction) by the impeller 31 . Through this operation, the efficiency of inflow (recovery) of oil-water (contaminated water) can be increased.
즉, 임펠러(31)의 회전시에 선체(10)의 전방으로 물이 튀는 현상이 발생함에 따라 유출유가 밀려나는 문제 발생하는데, 이러한 문제점을 해결하기 위해 임펠러(31) 입구 상단의 20~30% 정도에 물튀김 방지막(32)을 결합함으로써 선체(10)의 전방에 존재하는 유출유 확산 문제를 해결한다. 상기 20~30%는 바람직한 일예이며, 필요에 따라서는 40~50%까지 막을 수도 있을 것이다.That is, when the impeller 31 rotates, water splashes in the front of the hull 10, resulting in a problem of spilled oil being pushed. To solve this problem, 20 to 30% of the top of the inlet of the impeller 31 By combining the anti-splashing film 32 with the degree, the spilled oil diffusion problem present in the front of the hull 10 is solved. The above 20 to 30% is a preferred example, and may be blocked up to 40 to 50% if necessary.
도 26a는 본 발명의 일실시예의 장치의 단면도를 위에서 본 것이다.26A is a top view of a cross-sectional view of an apparatus of one embodiment of the present invention.
임펠러 하우징(33)도 반으로 잘린 단면으로 나타나 있으며, 그 안에 임펠러(31)가 수용되어 있다. 임펠러(31)와 하우징(33)이 각각 2개가 도시되어 있는데, 이 갯수는 필요에 따라 바뀔 수 있으나, 임펠러(31)와 하우징(33)이 각각 1개인 경우(후술의 도 26b)에 비하면 도 26a과 같이 2개인 경우가 더 유수 유입의 효율이 더 좋을 것이다.The impeller housing 33 is also shown in a cross section cut in half, and the impeller 31 is accommodated therein. Two impellers 31 and two housings 33 are shown, but the number can be changed as needed, but compared to the case of one impeller 31 and one housing 33 (FIG. 26b described later), In the case of two as in 26a, the efficiency of running water inflow will be better.
도 26b는 본 발명의 다른 예의 장치의 단면도를 위에서 본 것이다.26B is a top view in cross section of another example device of the present invention.
전술한 바와 같이 도 26b는 유입부의 임펠러(31)가 1개인 점에서 도 26a나 도 3과 상이하다. 이러한 도 26b의 경우도 동작에는 전혀 문제가 없고, 다만, 도 26a처럼 임펠러(31)의 갯수가 많은 경우에 비해 다소 유입 효율이 낮을 수는 있다.As described above, FIG. 26B is different from FIG. 26A or FIG. 3 in that the inlet part has one impeller 31. In the case of FIG. 26B, there is no problem at all in the operation, however, the inflow efficiency may be slightly lower than in the case where the number of impellers 31 is large as in FIG. 26A.
도 27a는 저장부(40)를 나타내는 도면이다.27A is a diagram showing the storage unit 40.
도면에서 유입부(20)는 임펠러(31)나 임펠러 하우징(33) 등을 생략하고 단순화되어 도시되어 있다.In the drawing, the inlet 20 is shown simplified without impeller 31 or impeller housing 33.
유입된 오염수는 도면의 화살표와 같은 흐름을 거친다.The introduced contaminated water passes through the flow shown by the arrow in the drawing.
오염수는 저장부(40)의 뒷부분까지 이동하면서 밀도차에 의해 기름에 의해 오염된 밀도가 낮은 부분(기름)과 오염되지 않은 밀도가 높은 부분(물)으로 분리 되는데, 밀도가 높은 오염되지 않은 부분은 저장부(40)의 하단(또는 저장부(40)의 뒤쪽 하단)에 배치되는 배출부(50)를 통해 배출됨으로써 오염수의 정화가 가능하게 된다.As the contaminated water moves to the back of the storage unit 40, it is separated into a low-density part (oil) contaminated by oil and a high-density part (water) that is not contaminated by the density difference. The part is discharged through the discharge part 50 disposed at the lower end of the storage part 40 (or the rear lower part of the storage part 40), thereby enabling purification of contaminated water.
이 오염수가 저장부(40) 내에서 이동할 때 이동 시간이 길어질수록 오염된 부분과 그렇지 않은 부분으로의 분리가 좀 더 효과적으로 일어날 수 있기 때문에 정해진 저장부(40)의 용적 내에서 이동시간을 최대한 늘리는 것이 중요하다.When the contaminated water moves in the storage unit 40, the longer the transfer time is, the more effectively the separation into the contaminated part and the non-contaminated part can occur. It is important.
이를 위해 저장부(40) 내에는 오염수의 이동 시간을 늘려주기 위한 방해판으로서 전술한 수직 격벽(V0~V4)이 배치되는 것으로 볼 수도 있다.To this end, it may be considered that the above-described vertical partition walls V0 to V4 are disposed in the storage unit 40 as baffles to increase the movement time of contaminated water.
오염수는 이러한 방해판(배플)을 통과하면서 결과적으로 이동 거리가 증가하게 되고 그만큼 이동시간이 늘어나게 되어, 보다 효과적으로 오염된 부분과 오염되지 않은 부분으로 밀도차에 의한 분리가 일어날 수 있게 된다. 방해판이 저장부의 측면과 맞닿는 부분에는 필요에 따라 관통홀을 배치하여 효과적으로 오염수가 정체하지 않도록 할 수 있다.As the contaminated water passes through the baffle plate (baffle), the movement distance increases as a result, and the movement time increases accordingly, so that the contaminated water and the non-contaminated portion can be more effectively separated by the difference in density. Where the baffle plate comes into contact with the side surface of the storage unit, through-holes may be disposed as necessary to effectively prevent stagnation of contaminated water.
도 27a에는 여러개의 수직 격벽(V0, V1, V2, V3, V4)이 있다. 수직 격벽(V0)에는 하단부에 개구가 있다. 그 결과, 도 27a의 우측 하단 그림을 기준으로, 수직 격벽(V0)을 화살표처럼 가로지르는 물의 흐름이 발생하는 것을 알 수 있다.27A, there are several vertical barrier ribs (V0, V1, V2, V3, V4). The vertical bulkhead V0 has an opening at its lower end. As a result, based on the lower right picture of FIG. 27A , it can be seen that water flows across the vertical bulkhead V0 like an arrow.
또한, 수직 격벽(V1~V3)에는, 도 27a의 우측 상단에 도시된 바와 같이, 중간부에 개구가 있다. 이러한 개구를 통해, 도 27a의 우측 하단 그림을 기준으로, 수직 격벽(V1~V3)을 화살표처럼 가로지르는 물의 흐름이 발생하는 것을 알 수 있다.Further, as shown in the upper right corner of Fig. 27A, the vertical partition walls V1 to V3 have an opening in the middle. Through this opening, it can be seen that water flows across the vertical bulkheads V1 to V3 like an arrow, based on the lower right picture of FIG. 27A.
이처럼 여러 수직 격벽(특히, V1~V3)을 거치게 되면서 낮은 유속으로 흐름이 형성된다. As it passes through several vertical partition walls (in particular, V1 to V3), a flow is formed at a low flow rate.
수직 격벽(V4)에는 하단부에 개구가 있다. 그 결과, 도 27a의 우측 하단 그림을 기준으로, 수직 격벽(V4)을 화살표처럼 가로지르는 물의 흐름이 발생하는 것을 알 수 있다.The vertical bulkhead V4 has an opening at its lower end. As a result, it can be seen that water flows across the vertical bulkhead V4 like an arrow, based on the lower right picture of FIG. 27A.
물론 도시된 수직 격벽(V0~V4)의 형상은 일예이며, 반드시 이러한 도시처럼 한정되지는 않는다.Of course, the shapes of the illustrated vertical partition walls V0 to V4 are examples, and are not necessarily limited to those illustrated.
오염수 중에 포함된 일정 크기 이상의 유출유 입자는 배출되는 속도보다 부상속도가 더 빠르기 때문에 해수면에 떠오르지만, 일정 크기 이하의 유출유 입자는 배출 흐름에 더 영향을 받게 되어 선체(10)의 외부로 배출되는 경우가 있다. 따라서, 일정 크기 이하의 유출유 입자가 더 쉽게 부상할 수 있도록 수직 격벽(V1~V3)을 통해 부상 시간을 확보한다.Oil spilled particles of a certain size or larger included in the contaminated water float on the sea surface because the floating speed is faster than the discharge speed, but oil spilled particles of a certain size or smaller are more affected by the discharge flow and are discharged to the outside of the hull (10). may be released. Therefore, the floating time is secured through the vertical bulkheads (V1 to V3) so that spilled oil particles of a certain size or less can float more easily.
여러 수직 격벽(V0~V4, 그 중에서도 특히, V1~V3)을 통해 격벽 사이마다 원형 와류를 형성시켜 해수면 근처로 유출유가 합류될 수 있도록 구조를 형성한다.Through several vertical bulkheads (V0 to V4, in particular, V1 to V3), a circular vortex is formed between the bulkheads to form a structure so that the spilled oil can join near the sea level.
도면과는 다소 달리, 수직 격벽(V1~V3)이 메쉬를 갖는 필터 구조라도 좋다.Somewhat different from the drawing, a filter structure in which the vertical partition walls V1 to V3 have a mesh may be used.
물론, 일부는 벽이고 일부는 필터라도 좋다.Of course, some are walls and some are filters.
또한, 수직 격벽(V1~V3)이 물과 기름을 분리할 수 있는 비중차 필터라도 좋다.Further, the vertical partition walls V1 to V3 may be a specific gravity difference filter capable of separating water and oil.
그리고, 도 27a에는 수평 격벽(H1)이 존재한다.And, in FIG. 27A, there is a horizontal partition wall H1.
수평 격벽(H1)은, 수직 격벽(V1~V3)을 통해서도 부상시키지 못한 유출유 입자를 필터링 하기 위해 설치한 구조물이다.The horizontal bulkhead H1 is a structure installed to filter out spilled oil particles that could not float even through the vertical bulkheads V1 to V3.
즉, 도 27a의 우측 하단 그림에 전체적인 물의 흐름이 화살표로 표시되어 있는데, 가장 마지막에 아래를 향하는 작은 화살표 4개가 수평 격벽(H1)을 향해 있는것을 볼 수 있다. 이 수평 격벽(H1)에서 미세한 기름 입자를 필터링하여, 아래로 배출되지 못하도록 한다.That is, in the lower right picture of FIG. 27A, the overall flow of water is indicated by arrows, and at the end, it can be seen that four small arrows pointing downward are directed toward the horizontal bulkhead H1. In this horizontal bulkhead (H1), fine oil particles are filtered and prevented from being discharged downward.
수평 격벽(H1)을 거치고 난 물은 배출구(50)를 통해 배출된다.The water passing through the horizontal bulkhead H1 is discharged through the outlet 50.
도 27b는 도 27a의 다른 실시예를 나타내는 도면이다.FIG. 27B is a diagram illustrating another embodiment of FIG. 27A.
도 27b는 도 27a와 거의 비슷하나, 수직 격벽의 갯수나, 유입구의 높이 등에 약간의 차이가 있다. 그럼에도 불구하고, 동작의 원리는 실질적으로 동일하다. 또한, 수평 격벽(H1)이 미세한 기름입자를 필터링한다.Figure 27b is almost similar to Figure 27a, but there is a slight difference in the number of vertical bulkheads or the height of the inlet. Nevertheless, the principle of operation is substantially the same. In addition, the horizontal bulkhead H1 filters fine oil particles.
수평 격벽(H1)은 도 27a처럼 배출구(50)와 다소 거리를 두고 있어도 되고, 도 27b처럼 배출구(50)와 인접해 있어도 무방하다.The horizontal bulkhead H1 may be slightly separated from the discharge port 50 as shown in FIG. 27A, or adjacent to the discharge port 50 as shown in FIG. 27B.
도 28a에는 도 27a, 도 27b에서 설명한 수평 격벽(H1)의 일예가 도시되어 있다.28A shows an example of the horizontal bulkhead H1 described in FIGS. 27A and 27B.
도 28b에도 마찬가지로, 도 27a, 도 27b에서 설명한 수평 격벽(H1)의 일예가 도시되어 있다.Similarly, FIG. 28B shows an example of the horizontal bulkhead H1 described in FIGS. 27A and 27B.
도 28a와 도 28b에서 보듯이, 수평 격벽(H1)은 여러겹일 수도 있고, 형상이 다소 상이한 것이 섞여 있을 수도 있고, 필요에 따라서 지지 테두리나 지지 중심선 등을 설치할 수도 있다.As shown in FIGS. 28A and 28B , the horizontal bulkhead H1 may be multi-layered, or may have slightly different shapes, or may be provided with a support rim or a support center line as necessary.
회수율(일예로 400L/min 정도, 예컨대, 350~450L/min)에 영향을 주지 않는 메시망 사이즈를 선정(일예로 100mesh, 예컨대, 80~120mesh)하여 배출 흐름에 더 큰 영향을 받는 기름입자(즉, 미세한 기름 입자)를 필터링할 수 있다.By selecting a mesh size (eg 100 mesh, eg 80 to 120 mesh) that does not affect the recovery rate (eg 400 L/min, eg 350 to 450 L/min), the oil particles ( That is, fine oil particles) can be filtered.
그리고, 도 27a, 27b에서는 수직 격벽(V1~V3)은 구멍이 있는 재료로 설명하였으나, 도 28a, 28b에 나타난 수평 격벽(H1)의 재료를 이용하여 수직 격벽을 형성하는 것도 가능하다. 이 경우, 회수율이나 메시망 사이즈는 반드시 수평 격벽의 그것과 동일할 필요는 없을 것이다.Also, in FIGS. 27A and 27B, the vertical barrier ribs V1 to V3 are described as a material with holes, but it is also possible to form the vertical barrier rib using the material of the horizontal barrier rib H1 shown in FIGS. 28A and 28B. In this case, the recovery rate or mesh size may not necessarily be the same as that of the horizontal bulkhead.
도 29a는 선체(10)에 빌지 킬(BK1~BK4)이 설치된 모습을 나타낸다.29A shows a state in which bilge keels (BK1 to BK4) are installed in the hull 10.
도 29b는 도 29a의 단면도이다.29B is a cross-sectional view of FIG. 29A.
선체(10)의 모습은 도 3 등과 다소 상이하지만, 동작 원리는 대동소이하다. 도 29a, 도 29b에서 선체(10)의 전후좌우에 빌지 킬(Bilge Keel; BK1~BK4)이 설치되어 있다.Although the appearance of the hull 10 is somewhat different from FIG. 3 and the like, the operation principle is largely the same. 29a and 29b, bilge keels (Bilge Keels; BK1 to BK4) are installed on the front, rear, left and right sides of the hull 10.
도 29c는 빌지 킬이 설치될 위치를 선정하기 위한 실험을 설명한다.29c describes an experiment for selecting a location where a bilge keel will be installed.
도 29c에 의하면, 예컨대, 좌우의 바닥(즉, 하방)에 빌지 킬을 설치하는 경우에 비해, 좌우 측면에 빌지 킬(즉, BK1, BK2)을 설치하는 것이 더 요동을 줄이는 효과가 큰 것을 알 수 있다.According to FIG. 29C, it can be seen that, for example, installing bilge keels (ie, BK1, BK2) on the left and right sides has a greater effect of reducing shaking than when bilge keels are installed on the left and right floors (ie, below). can
또한, 전면에 빌지 킬(즉, BK3)을 설치하는 것도 나름대로의 효과를 갖는 것을 알 수 있다. In addition, it can be seen that installing a bilge keel (ie, BK3) on the front has its own effect.
이러한 실험에 의거하여, 도 29a, 도 29b와 같은 위치에 빌지 킬(BK1~BK4)을 설치하였다.Based on these experiments, bilge keels (BK1 to BK4) were installed in the same positions as shown in FIGS. 29a and 29b.
도 29d는 빌지 킬의 유무에 따른 결과를 나타낸다.29d shows the results according to the presence or absence of bilge keel.
빌지 킬이 있는 경우는, 없는 경우에 비해, 해수면 상황 레벨 1에서는 피칭이 53% 감소하고, 해수면 상황 레벨 2에서는 피칭이 37% 감소하고, 해수면 상황 레벨 3(파도 높이 1~1.25미터)에서도 안전한 운행이 가능함을 알 수 있다.Compared to no bilge keel, pitching is reduced by 53% in sea level situation level 1, pitching reduced by 37% in sea level situation level 2, and safe even in sea level level 3 (wave height 1-1.25 meters). It can be seen that operation is possible.
도 30a는 수직 격벽을 위에서 본 모양을 나타내는 단면도이다.Fig. 30A is a cross-sectional view showing a vertical bulkhead as viewed from above.
수직 격벽은 반드시 도 27a, 27b의 수직 격벽(V0~V3)과 같은 형상일 필요는 없고, 도 30a의 수직 격벽(VW1~VW11)과 같은 형상일 수도 있다.The vertical barrier rib does not necessarily have to have the same shape as the vertical barrier ribs V0 to V3 of FIGS. 27A and 27B, and may have the same shape as the vertical barrier ribs VW1 to VW11 of FIG. 30A.
도 27a, 27b의 수직 격벽(V0~V3)에는 아래에 공간(개구)이 있거나 중간에 개구가 있었다. 물론 그에 한정되는 것은 아니고, 필요에 따라서는, 위에 개구가 있거나, 아래에 개구가 있거나, 아래/위에 모두 개구가 있거나, 중간에 개구가 있을 수 있다.The vertical bulkheads V0 to V3 in FIGS. 27A and 27B have a space (opening) below or an opening in the middle. Of course, it is not limited thereto, and, if necessary, there may be an opening at the top, an opening at the bottom, an opening at both the bottom/above, or an opening in the middle.
도 30a의 격벽도 마찬가지로, 위에 개구가 있거나, 아래에 개구가 있거나, 아래/위에 모두 개구가 있거나, 중간에 개구가 있을 수 있다. 그리고, 도 30a와 같이 위에서 보았을 때의 쐐기 형상 자체로도 유수 분리에 적절한 물의 흐름 경로를 형성할 수 있다.Similarly, the bulkhead of FIG. 30A may have an opening at the top, an opening at the bottom, an opening at both the bottom/above, or an opening at the middle. In addition, as shown in FIG. 30A, even a wedge shape when viewed from above can form a water flow path suitable for oil-water separation.
도 30b는 저장부(40) 내부에 수직/수평 격벽이 형성된 다른 실시예를 나타낸다.30B shows another embodiment in which vertical/horizontal barrier ribs are formed inside the storage unit 40 .
(a)는 수평 배플(날개형 배플)을 나타낸다. 배플은 전술한 수직/수평 격벽과 동일한 의미이다.(a) shows a horizontal baffle (winged baffle). The baffle has the same meaning as the aforementioned vertical/horizontal bulkhead.
수평 배플은 상하 유동(언덕 주행, 종동요)에 효과가 크다. Horizontal baffles are highly effective for up-and-down flow (hill driving, pitching).
최적의 위치는 자유 표면보다 약간 더 잠긴 때에 더 효과가 크다.The optimal position is more effective when slightly more submerged than on the free surface.
그리고, 수면 근처에서 효과가 우수하고, 수면 아래로 갈수록 급감한다.In addition, the effect is excellent near the surface of the water and rapidly decreases as it goes below the surface of the water.
또한, 최적 길이는 탱크 폭의 10%(한쪽 기준)이며, 더 길어도 효과 상승은 거의 없다. 예컨대, 탱크 폭의 7~13%일 수 있다. 도 30b의 (a)처럼 물 흐름의 좌측에 10% 정도, 우측에 10% 정도 길이를 차지할 수 있다.In addition, the optimal length is 10% of the tank width (based on one side), and even if it is longer, there is almost no increase in effect. For example, it may be 7-13% of the tank width. As shown in (a) of FIG. 30B, it may occupy about 10% of the length on the left side of the water flow and about 10% on the right side of the water flow.
(a)의 그림은 탱크의 폭을 기준으로 수치(비율)를 나타낸 것이다.The figure in (a) shows the numerical value (ratio) based on the tank width.
최적 길이의 예시로는 9.4%(예컨대, 0.08m)가 좌측에 하나, 또 9.4%가 우측에 하나 설치되어 있을 수 있다.As an example of the optimal length, one 9.4% (eg, 0.08 m) may be installed on the left side and another 9.4% may be installed on the right side.
최적 높이는 수위의 90%(바닥으로부터 수면까지를 100%라 했을 때)이다. 예컨대, 85~95%일 수 있다.The optimum height is 90% of the water level (when the distance from the bottom to the water surface is 100%). For example, it may be 85 to 95%.
(b)는 수직 배플(격막형 배플)을 나타낸다.(b) shows a vertical baffle (diaphragm type baffle).
이는 좌우 유동(코너 주행, 횡동요)에 효과가 크다.This is highly effective for left and right movement (corner driving, rollover).
자유표면(수면)까지 연장되어야 효과가 있고, 더 높으면 거의 효과가 없었다.It has to be extended to the free surface (water surface) to be effective, and if it is higher, it has little effect.
최적 길이는 전체 높이의 76%(일예로, 0.19m)이다. 예컨대, 70~85%일 수 있다.The optimal length is 76% of the total height (eg, 0.19 m). For example, it may be 70-85%.
(c)는 수직 배플(격막형 배플)을 나타낸다.(c) shows a vertical baffle (diaphragm type baffle).
최적 깊이는 큰 관계는 없었다. 자유표면(수면) 근처가 최적으로 생각되지만, 차이가 크지는 않았다.There was no significant relationship with the optimal depth. Near the free surface (water surface) is considered optimal, but the difference is not large.
최적 길이는 탱크의 바닥에서 수면까지의 높이의 44% 정도였으며, 더 길어도 효과 상승은 거의 없었다. 예컨대, 40~55%일 수 있다.The optimal length was about 44% of the height from the bottom of the tank to the water surface, and there was little increase in the effect even if it was longer. For example, it may be 40-55%.
(a)~(c)를 종합해 보면, 수직/수평 격벽을 이용하여 내부 유출유 및 바닷물 유동을 억제시켜 주행안정성을 확보한다.In summary of (a) to (c), driving stability is secured by using vertical/horizontal bulkheads to suppress the flow of internal spilled oil and seawater.
기름회수 장치의 좌우 폭 기준 10%에 해당하는 수평 격벽 면적을 설정하고, 기름회수 장치 내 수위 기준 90%(해수면에 가까운 방향)에 해당하는 부분에 수평 격벽 위치를 설정하면 좋다.It is good to set the horizontal bulkhead area corresponding to 10% of the left and right width of the oil recovery device, and to set the horizontal bulkhead position at the part corresponding to 90% of the water level standard (direction close to sea level) in the oil recovery device.
오염수는 저장부(40)의 뒷부분까지 이동하면서 밀도차에 의해 기름에 의해 오염된 밀도가 낮은 부분(기름)과 오염되지 않은 밀도가 높은 부분(물)으로 분리 되는데, 밀도가 높은 오염되지 않은 부분은 저장부(40)의 하단 또는 저장부(40)의 뒤쪽 하단에 배치되는 배출부(50)를 통해 배출됨으로써 오염수의 정화가능하게 된다.As the contaminated water moves to the back of the storage unit 40, it is separated into a low-density part (oil) contaminated by oil and a high-density part (water) that is not contaminated by the density difference. The part is discharged through the discharge part 50 disposed at the lower end of the storage part 40 or the rear lower part of the storage part 40, so that the contaminated water can be purified.
이 오염수가 저장부(40) 내에서 이동할 때 이동 시간이 길어질수록 오염된 부분과 그렇지 않은 부분으로의 분리가 좀 더 효과적으로 일어날 수 있기 때문에 정해진 저장부(40)의 용적 내에서 이동시간을 최대한 늘리는 것이 중요하다.When the contaminated water moves in the storage unit 40, the longer the transfer time is, the more effectively the separation into the contaminated part and the non-contaminated part can occur. It is important.
이를 위해 저장부(40) 내에는 오염수의 이동 시간을 늘려주기 위한 방해판(배플)이 전술한 수직 격벽(V0~V3 또는 VW1~VW11)으로서 배치된다. 일예로, 방해판은 저장부(40)의 상부와 하부에 모두 고정되고 연결부(30)를 향하는 쐐기 형상일 수 있다. 물론, 전술한 바와 같이, 상부와 하부로부터 일정 거리 떨어진 다른 예일 수도 있다.To this end, baffles (baffles) for increasing the movement time of contaminated water are disposed in the storage unit 40 as the aforementioned vertical partition walls V0 to V3 or VW1 to VW11. For example, the baffle plate may have a wedge shape fixed to both the upper and lower portions of the storage unit 40 and facing the connection unit 30 . Of course, as described above, it may be another example that is a certain distance from the top and bottom.
오염수는 이러한 방해판(배플)을 통과하면서 결과적으로 이동 거리가 증가하게 되고 그만큼 이동시간이 늘어나게 되어, 보다 효과적으로 오염된 부분과 오염되지 않은 부분으로 밀도차에 의한 분리가 일어날 수 있게 된다. 방해판이 저장부의 측면과 맞닿는 부분에는 필요에 따라 관통홀을 배치하여 효과적으로 오염수가 정체하지 않도록 할 수 있다.As the contaminated water passes through the baffle plate (baffle), the movement distance increases as a result, and the movement time increases accordingly, so that the contaminated water and the non-contaminated portion can be more effectively separated by the difference in density. Where the baffle plate comes into contact with the side surface of the storage unit, through-holes may be disposed as necessary to effectively prevent stagnation of contaminated water.
선체(10)의 좌우에는 부력 장치가 배치되는데,이는 속이 비어서 수밀된 금속 또는 비금속 재질의 튜브가 될 수 있다. 저장부(40)의 본체에는 하단에 배출부(50)가 배치되어 선체(10)에 부력을 부여할 수 없기 때문에 선체(10)에 부력을 주기 위해 추가적인 부력장치가 필요하다. 이러한 부력장치는 선체(10)의 전후진 방향에서 영향을 주지 않기 위해 좌우에 배치한다. 도 1에 도시된 저장부(40)가 그 좌우측단에서 부력 장치의 역할을 하도록(즉, 도 3의 저장부(40)의 내부의 좌우측단에 미도시의 부력 장치가 있도록) 구성할 수도 있고, 상기 도 3에 도시된 저장부(40)의 외부에 부력 장치를 부착해도 좋다. Buoyancy devices are disposed on the left and right sides of the hull 10, which may be hollow and watertight tubes made of metal or non-metal. An additional buoyancy device is required to impart buoyancy to the hull 10 because the discharge unit 50 is disposed at the bottom of the main body of the storage unit 40 and cannot impart buoyancy to the hull 10. These buoyancy devices are placed on the left and right so as not to affect the forward and backward directions of the hull (10). The storage unit 40 shown in FIG. 1 may be configured to serve as a buoyancy device at its left and right ends (ie, there is a buoyancy device not shown at the left and right ends inside the storage unit 40 of FIG. 3), , A buoyancy device may be attached to the outside of the storage unit 40 shown in FIG. 3 .
