Description

本発明は、水槽底面の溝に溜まった沈殿物を排除するために所定箇所まで移動させる沈殿物排除装置、及び水槽内で稚魚や稚エビ等の水産物を養殖するための養殖装置に関する。   The present invention relates to a sediment removing device that moves to a predetermined location in order to exclude sediment accumulated in a groove on the bottom of a water tank, and an aquaculture device for cultivating marine products such as fry and shrimp in the water tank.

稚魚や稚エビ等の水産物を養殖する方法としては海上養殖と陸上養殖があり、何れの養殖方法においても、高密度で養殖が行なわれることが多く、水槽底面には水産物の***物、脱皮殻、死骸、餌の食べ残し等の沈殿物が溜まり易いという課題がある。

JP 2003-23914 A

特許文献１の水産物養殖装置に関しては、これを実施するに際し、特に問題があるものではない。
しかしながら、本発明の目的は、水槽底面に溜まる沈殿物を排除するために所定箇所まで移動させるための手段として、特許文献１とは異なる沈殿物排除装置を提供すると共に、この沈殿物排除装置を備える水産物養殖装置を提供することである。 The marine product aquaculture apparatus of Patent Document 1 is not particularly problematic in carrying out this.
However, an object of the present invention is to provide a sediment removal device different from Patent Document 1 as a means for moving to a predetermined location in order to eliminate the sediment accumulated on the bottom of the water tank. It is to provide an aquaculture device equipped.

本発明では、水槽底面に形成された溝に溜まった沈殿物を排除するために所定箇所まで移動させる装置であって、前記溝の内部を走行可能なように走行輪が設けられた本体部と、下端辺が前記溝の底面に当接するまで回動するように前記本体部の前端に枢着された板状部材と、前記板状部材に掛合された索状体と、前記本体部を前後いずれかの方向に走行させるべく前記索状体を引張る牽引手段とを備え、前記板状部材は、本体部を前方向に走行させるべく牽引手段で引張ったときに下端辺が前記溝の底面に当接し、沈殿物を掻き集めながら溝の所定箇所まで移動させ、逆に、本体部を後方向に走行させるべく索状体を引張ったときには下端辺と前記溝の底面との間に隙間ができるように、前記本体部に枢着されたものである水槽内沈殿物排除装置が提供される。   In the present invention, in order to eliminate the sediment accumulated in the groove formed on the bottom surface of the water tank, the apparatus moves to a predetermined location, and a main body provided with traveling wheels so as to be able to travel inside the groove; A plate-like member pivotally attached to the front end of the main body portion so as to rotate until the lower end side comes into contact with the bottom surface of the groove; a cord-like body hooked on the plate-like member; Traction means for pulling the cord-like body to travel in any direction, and the plate-like member has a lower end side on the bottom surface of the groove when the body portion is pulled by the traction means to travel in the forward direction. Abutting and scraping deposits, moving to a predetermined location in the groove, conversely, when pulling the cord-like body to run the main body backward, a gap is created between the lower end side and the bottom surface of the groove In the water tank, which is pivotally attached to the main body. Apparatus is provided.

また本発明では、稚魚や稚エビ等の水産物を養殖するための水槽内の底面にほぼ直線状に延長する溝が設けられ、該溝には沈殿物を排除するため所定箇所まで移動させる沈殿物排除手段が設けられた水産物の養殖装置において、前記沈殿物排除手段は、前記溝の内部を走行可能なように走行輪が設けられた本体部と、前記本体部の前端に枢着され下端辺が前記溝の底面に当接するまで回動可能に設けられた板状部材と、前記板状部材に掛合されて前記溝両端を介して水槽外まで延設された索状体と、前記索状体を正逆いずれかの方向に引張るため水槽外に設けられた牽引手段とを備えることを特徴とする水産物養殖装置が提供される。   Further, in the present invention, a groove extending in a substantially straight line is provided on the bottom surface of the aquarium for culturing marine products such as fry and fry shrimp, and the groove is moved to a predetermined place to eliminate the precipitate. In the aquaculture device provided with the exclusion means, the sediment exclusion means includes a main body portion provided with a traveling wheel so as to be able to travel in the groove, and a lower end side pivotally attached to a front end of the main body portion. A plate-like member provided so as to be rotatable until it comes into contact with the bottom surface of the groove, a cord-like member hooked on the plate-like member and extended to the outside of the water tank through both ends of the groove, and the cord-like member There is provided an aquaculture device characterized by comprising a pulling means provided outside the water tank for pulling the body in either the forward or reverse direction.

本発明の水槽内沈殿物排除装置では、本体部を前方向に走行させるべく、索状体を介して板状部材を牽引手段で引張ると、板状部材の下端辺は溝の底面に当接し、沈殿物を掻き集めながら溝の所定箇所まで移動させることが可能になる。逆に、本体部を後方向に走行させるべく索状体を介して板状部材を牽引手段で引張ると、板状部材の下端辺と溝の底面との間には隙間ができるため、本体部を後方向に走行させた場合にも、板状部材の下端辺が沈殿物を逆方向に押し戻すことは防止される。
したがって、本体部を前後方向に往復走行させることにより、水槽底面の溝に溜まった沈殿物を所定箇所まで効率的に集めることが可能になり、例えば、ベルトコンベア等の搬送装置と比較すると、水槽内沈殿物排除装置自体のメンテナンスの手間が格段に簡易にできて、必要なときのみ稼動させればよいため省エネルギー効果も得られる。また水槽内沈殿物排除装置は簡略な構造であるため故障し難いという利点もある。 In the apparatus for removing sediment in the aquarium according to the present invention, when the plate member is pulled by the traction means through the cord-like body so as to run the main body portion in the forward direction, the lower end side of the plate member contacts the bottom surface of the groove. It is possible to move to a predetermined position in the groove while collecting the precipitate. On the contrary, when the plate member is pulled by the traction means through the cord-like body to run the main body portion backward, a gap is formed between the lower end side of the plate member and the bottom surface of the groove. Even when the vehicle is moved backward, the lower end side of the plate-like member is prevented from pushing back the sediment in the reverse direction.
Therefore, by reciprocating the main body part in the front-rear direction, it becomes possible to efficiently collect the sediment accumulated in the groove on the bottom of the water tank up to a predetermined location. For example, when compared with a conveyor device such as a belt conveyor, The maintenance work of the inner sediment removing device itself can be greatly simplified, and an energy saving effect can be obtained because it only has to be operated when necessary. Moreover, since the deposit removal apparatus in a water tank is a simple structure, there also exists an advantage that it is hard to break down.

本発明の水産物養殖装置では、沈殿物排除手段により沈殿物が効率的に集められて排出されることで、水の劣化が抑えられ、水産物の病気の発生が抑制される。また一日に複数回実施する給餌のうち、所定回の給餌の直前に沈殿物排除手段で沈殿物を集められば、水産物が食べ残した餌の量を把握することが可能になり、したがって、適正な給餌量を割り出すことが可能になる。   In the aquaculture apparatus of the present invention, the sediment is efficiently collected and discharged by the sediment removing means, so that deterioration of water is suppressed and the occurrence of fishery disease is suppressed. Also, among the feedings that are carried out several times a day, if the sediment is collected by the sediment exclusion means immediately before the predetermined number of feedings, it becomes possible to grasp the amount of food left by the seafood, It is possible to determine an appropriate feeding amount.

以下、図面を参照して本発明の実施形態について説明するが、本発明はこれに限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited thereto.

The As the artificial seaweed, a conventional artificial seaweed as described in Patent Document 1 is used and suspended in the aquaculture tank 11 by conventional means.

次に、図５及び図６を参照して沈殿物排除装置２０について説明する。
沈殿物排除装置２０は、本体部２１と、スクレーパー２２（板状部材）と、ロープ２３，２４（索状体）と、ウインチ２５，２６（牽引手段）とを主要な構成として備えるものである。 Next, the sediment removing apparatus 20 will be described with reference to FIGS. 5 and 6.
The sediment removing device 20 includes a main body 21, a scraper 22 (plate-like member), ropes 23 and 24 (cord-like body), and winches 25 and 26 (traction means) as main components. .

本体部２１は両側部に比較的低く立ち上げられた側壁２１ａが形成され、各側壁２１ａの外面の２箇所には車輪２１ｂが取り付けられ、底面２１ｃにも、４箇所に車輪２１ｄが取り付けられている。底面２１ｃの車輪２１ｄは、溝１５の底面１５ａを走行するためのものであり、側壁２１ａの車輪２１ｂは、本体部２１やスクレーパー２２が溝１５の側面１５ｂへ接触しないようにガイドするためのものである。また本体部２１の前端付近にはブラケット２１ｅが立設され、ブラケット２１ｅにはストッパー２１ｆが設けられ、ストッパー２１ｆはスクレーパー２２の後方への回動範囲を図５（ｂ）に図示した角度に規定するものである。   The main body 21 is formed with side walls 21a raised relatively low on both sides, wheels 21b are attached to two places on the outer surface of each side wall 21a, and wheels 21d are also attached to the bottom face 21c at four places. Yes. The wheel 21d on the bottom surface 21c is for traveling on the bottom surface 15a of the groove 15, and the wheel 21b on the side wall 21a is for guiding the main body 21 and the scraper 22 so as not to contact the side surface 15b of the groove 15. It is. Also, a bracket 21e is erected in the vicinity of the front end of the main body 21, and a stopper 21f is provided on the bracket 21e. The stopper 21f defines the range of rotation of the scraper 22 to the angle shown in FIG. 5B. To do.

スクレーパー２２は背面にフランジ２２ａが突設され、このフランジ２２ａが、本体部２１のブラケット２１ｅにボルトやナット等で枢着される。スクレーパー２２は下端辺２２ｂが曲げられており、この下端辺２２ｂが溝１５の底面１５ａに接触して沈殿物を掻き取る。またスクレーパー２２の上端には上端壁２２ｃが形成され、両側部には側壁２２ｄが形成され、これら上端壁２２ｃと側壁２２ｄとで囲まれた部分が沈殿物の収容部２２ｅとして機能し、掻き取られた沈殿物が収容部２２ｅに溜められて所定箇所まで運ばれる。スクレーパー２２には、前面の上端付近からブラケット２１ｅに延びる取手２２ｆが設けられ、図５（ｂ）に示したように、この取手２２ｆの２箇所にロープ２３，２４が掛合されている。   The scraper 22 has a flange 22a projecting on the back surface, and the flange 22a is pivotally attached to a bracket 21e of the main body 21 with bolts, nuts, or the like. The scraper 22 has a lower end side 22b bent, and the lower end side 22b comes into contact with the bottom surface 15a of the groove 15 to scrape the precipitate. Further, an upper end wall 22c is formed on the upper end of the scraper 22, and side walls 22d are formed on both side portions. A portion surrounded by the upper end wall 22c and the side wall 22d functions as a sediment containing portion 22e. The deposited precipitate is stored in the accommodating portion 22e and is carried to a predetermined location. The scraper 22 is provided with a handle 22f extending from the vicinity of the upper end of the front surface to the bracket 21e. As shown in FIG. 5B, ropes 23 and 24 are engaged with the two positions of the handle 22f.

ロープ２３，２４はスクレーパー２２の取手２２ｆから、図２の一点鎖線で示したように、溝１５に沿ってそれぞれ前後両方向に延長し、養殖水槽１１の前壁１４ｂと後壁１４ｃに設けられたプーリー１８を介して養殖水槽１１の外部に達し、さらに他のプーリー１８を介してウインチ２５，２６まで延びている。これらウインチ２５，２６は、いずれか一方がロープ２３，２４を巻き込んでいるとき、他方がロープ２３，２４を巻き出し可能なように構成されている。したがって、ロープ２３，２４の一方を介して、それぞれウインチ２５，２６で牽引することにより、本体部２１及びスクレーパー２２は、溝１５内におけるＰ１方向あるいはＰ２方向に走行可能なように構成されている。   The ropes 23 and 24 extend from the handle 22f of the scraper 22 in both front and rear directions along the groove 15 as shown by the one-dot chain line in FIG. 2, and are provided on the front wall 14b and the rear wall 14c of the aquaculture tank 11. It reaches the outside of the aquaculture tank 11 via a pulley 18 and further extends to winches 25 and 26 via another pulley 18. These winches 25 and 26 are configured such that when one of them winds the ropes 23 and 24, the other can unwind the ropes 23 and 24. Therefore, the main body 21 and the scraper 22 are configured to be able to travel in the P1 direction or the P2 direction in the groove 15 by being pulled by the winches 25 and 26 through one of the ropes 23 and 24, respectively. .

図６において、スクレーパー２２はロープ２３により矢印Ｐ１方向に牽引されており、この牽引力によりスクレーパー２２は回動し、その下端辺２２ｂが溝１５の底面１５ａに当接する。この当接状態で本体部２１を矢印Ｐ１方向に牽引すると、スクレーパー２２の下端辺２２ｂが溝１５内の沈殿物を掻き取りながら、沈殿物を収容部２２ｅに溜めて所定箇所まで押し運ぶことができる。
逆に、図５（ｂ）においては、スクレーパー２２はロープ２４により矢印Ｐ２方向に牽引されており、ブラケット２１ｅがストッパー２１ｆに当接した状態で回動停止している。このとき、下端辺２２ｂと溝１５の底面１５ａとの間には隙間２７ができているため、本体部２１を牽引して矢印Ｐ２方向に走行させた場合にも、スクレーパー２２の下端辺２２ｂが、沈殿物を矢印Ｐ２方向に押し戻すことは防止される。 In FIG. 6, the scraper 22 is pulled in the direction of the arrow P <b> 1 by the rope 23, and the scraper 22 is rotated by this pulling force, and the lower end side 22 b abuts against the bottom surface 15 a of the groove 15. When the main body 21 is pulled in the direction of arrow P1 in this contact state, the lower end side 22b of the scraper 22 scrapes off the precipitate in the groove 15, and accumulates the precipitate in the accommodating portion 22e and pushes it to a predetermined location. it can.
On the other hand, in FIG. 5B, the scraper 22 is pulled by the rope 24 in the direction of the arrow P2, and is stopped while the bracket 21e is in contact with the stopper 21f. At this time, since a gap 27 is formed between the lower end side 22b and the bottom surface 15a of the groove 15, the lower end side 22b of the scraper 22 is also pulled when the main body 21 is pulled and traveled in the direction of the arrow P2. Pushing the precipitate back in the direction of arrow P2 is prevented.

次に、水産物養殖場１０の作用について説明する。
水産物養殖場１０では、例えば、造波装置１２等により養殖水槽内に波を発生させると、人工海藻が揺動し、この人工海藻の下端が養殖水槽の底面に接触しているため、養殖水槽底面に沈んだ水産物の***物、抜け殻、死骸、餌の食べ残し等の沈降物は人工海藻に動かされて、底面の勾配に導かれて溝１５に達する。このように溝１５に導かれた沈降物は、沈殿物排除装置２０により、前壁１４ｂ付近すなわち溝前端１５ｂまで運ばれる。この溝前端１５ｂにおいて、沈降物は慣用の水中ポンプやエアリフト等により引き上げられ、フィルター等の手段で固形物を除去した後に、水浄化ユニット１３において処理される。
本発明の水産物の養殖設備１０では、沈殿物排除装置２０により沈殿物が効率的に集められて排出されることで、水の劣化が抑えられ、水産物の病気の発生が抑制される。
なお、本発明において、養殖水槽１１内で沈降物が溝１５まで導びかれる手段に関しては、上記の造波装置１２や人工海藻等の態様に限定されるものではない。 Next, the operation of the aquaculture farm 10 will be described.
In the aquaculture farm 10, for example, when a wave is generated in the aquaculture tank by the wave generator 12 or the like, the artificial seaweed swings, and the lower end of the artificial seaweed is in contact with the bottom surface of the aquaculture tank. Sediment such as seafood excrement, shells, carcasses, and uneaten food left on the bottom is moved by the artificial seaweed and led to the bottom slope to reach the groove 15. The sediment guided to the groove 15 in this way is carried by the sediment removing device 20 to the vicinity of the front wall 14b, that is, to the groove front end 15b. At the groove front end 15b, the sediment is pulled up by a conventional submersible pump, an air lift, or the like, and after the solid matter is removed by means such as a filter, it is processed in the water purification unit 13.
In the aquaculture equipment 10 according to the present invention, the sediment is efficiently collected and discharged by the sediment eliminating device 20, so that the deterioration of water is suppressed and the occurrence of fishery disease is suppressed.
In the present invention, the means for guiding the sediment to the groove 15 in the aquaculture tank 11 is not limited to the above-described wave generator 12 or artificial seaweed.
