Detailed Description

The present invention will be described in further detail with reference to the drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the substances, and not restrictive of the invention. It should be further noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

In the field of cage culture, a plurality of parallel cables are generally pulled in a shallow water area, cultured aquatic products are put into a culture net cage, and then the plurality of culture net cages filled with the aquatic products are uniformly hung on the cables.

As shown in fig. 1, 2 and3, the shipborne cavitation water jet aquaculture net cage cleaning device provided by the invention comprises a cage frame 1 matched with the shape of the aquaculture net cage, wherein the cage frame 1 is cylindrical formed by combining at least two circular arc frames, the diameter of the cage frame 1 is slightly larger than the outer diameter of the aquaculture net cage, the length of the cage frame 1 is slightly larger than the length of the aquaculture net cage, the cage frame 1 is in a frame structure, and two ends of the cage frame 1 are open, so that the aquaculture net cage can enter from one end of the cage frame 1 and be sent out from the other end of the cage frame 1. In the present invention, when the cultivation net cage is fed into the cage frame 1, the axis direction of the cultivation net holes is consistent with the axis direction of the cage frame 1.

The longitudinal rolling brushes 3 are arranged on the cage frame 1, both ends of the longitudinal rolling brushes 3 are rotatably supported on the cage frame 1, at least one group of longitudinal rolling brushes 3 is arranged, at least one longitudinal rolling brush 3 in the same group is arranged, and when the culture net cage enters from one end of the cage frame 1 and is sent out from the other end of the cage frame 1, the longitudinal rolling brushes 3 are fully rotated on the cage frame 1, so that the culture net cage can be driven to fully rotate in the cage frame 1 when passing through the cage frame 1. Because the diameter of the passing space in the cage frame 1 can be reduced when the longitudinal rolling brushes 3 are arranged, and the structural strength of the culture net cage is smaller, the culture net cage can generate certain shrinkage when being radially extruded, so that the longitudinal rolling brushes 3 can drive the culture net cage to synchronously rotate through friction between the longitudinal rolling brushes 3 and the culture net cage while rotating after the longitudinal rolling brushes 3 are installed, the minimum diameter of the passing space formed by the rolling surfaces of the longitudinal rolling brushes 3 in a surrounding way is slightly smaller than the outer diameter of the culture net cage after the longitudinal rolling brushes 3 are installed, or the minimum diameter of the passing space formed by the rolling surfaces of the longitudinal rolling brushes 3 and the inner wall of the cage frame 1 in a surrounding way is slightly smaller than the outer diameter of the culture net cage. The passage space here means a cylindrical space through which the cultivation net cage can pass.

The cage frame 1 is further provided with a plurality of cleaning heads 4, the plurality of cleaning heads 4 can be arranged at different positions of the cage frame 1, when the aquaculture net cage enters and passes through the cage frame 1, the cleaning heads 4 start to operate to clean the net cage, and the aquaculture net cage rotates while moving backwards, so that even if the positions of the cleaning heads 4 are not changed, the cleaning heads 4 can also finish cleaning the whole aquaculture net cage.

When the farming net cage needs to be cleaned, the cage frame 1 is carried on the shipboard of the operation ship, the operation ship advances along a cable for hanging the farming net cage, the relative position of the operation ship and the farming net cage changes through the advancing of the operation ship, when the front end of the cage frame 1 carried on the operation ship is close to the farming net cage, the farming net cage is pushed to be gradually inclined until the horizontal state when the cage frame 1 advances along with the operation ship due to no change of the position of the farming net cage, the upper end of the farming net cage gradually enters the front end of the cage frame 1, the farming net cage rotates when the farming net cage moves backwards in the cage frame 1 through the driving of the longitudinal rolling brush 3, the farming net cage is cleaned on the surface of the farming net cage through the cleaning head 4 in the rotating backward moving process, and finally, the farming net cage is smoothly sent out from the rear end of the cage frame 1 along with the continuing advancing of the operation ship, and the cleaning of the surface of the farming net cage is completed through the cleaning head 4.

The axial direction of the longitudinal rolling brush 3 is consistent with the axial direction of the cage frame 1, when the culture net cage enters the cage frame 1, the axial direction of the longitudinal rolling brush 3 is consistent with the axial direction of the culture net cage, and the rotation of the longitudinal rolling brush 3 and the friction between the longitudinal rolling brush 3 and the culture net cage enable the longitudinal rolling brush 3 to drive the culture net cage to rotate while rotating, so that the culture net cage can rotate in the process of entering and passing through the cage frame 1.

When the longitudinal rolling brush 3 is installed, two ends of the longitudinal rolling brush 3 are rotatably supported on the inner wall of the cage frame 1 through bearing seats; meanwhile, in the invention, when the longitudinal rolling brushes 3 are in one group, the length of the longitudinal rolling brushes 3 is matched with the length of the cage frame 1, and when the longitudinal rolling brushes 3 are in multiple groups, the total length of the multiple groups of longitudinal rolling brushes 3 is matched with the length of the cage frame 1. Of course, in the invention, the number of the longitudinal rolling brushes 3 in the same group can be one or more, when the number of the longitudinal rolling brushes 3 in the same group is one, the number of the longitudinal rolling brushes 3 in the same group is preferentially more, and when the number of the longitudinal rolling brushes 3 in the same group is multiple, the number of the longitudinal rolling brushes 3 in the same group can be one or more; meanwhile, when the number of the longitudinal rolling brushes 3 is one group or/and the number of the longitudinal rolling brushes 3 in each group is multiple, the longitudinal rolling brushes 3 in the same group are distributed at intervals along the circumferential direction of the cage frame 1, and when the number of the longitudinal rolling brushes 3 in each group is multiple, the longitudinal rolling brushes 3 in two adjacent groups can be distributed in a staggered manner. Through the common cooperation of a plurality of vertical round brushes 3, make the aquaculture net cage in getting into and through the whole in-process that sends out behind cage frame 1, the aquaculture net cage can both realize its rotary drive through the friction fit with vertical round brush 3 to guarantee the washing of cleaning head 4 to the aquaculture net cage.

As shown in fig. 1 and 3, the cage frame 1 is further provided with at least one set of transverse rolling brushes 2, when the transverse rolling brushes 2 are in one set, the set of transverse rolling brushes 2 are located at one end of the culture net cage, which first enters the cage frame 1, and when the transverse rolling brushes 2 are in two or more sets, two sets of transverse rolling brushes 2 are required to be located at two ends of the cage frame 1 respectively. When the transverse rolling brush 2 is arranged, the axial direction of the transverse rolling brush 2 is consistent with the chord length direction of the cage frame 1, namely, when the transverse rolling brush 2 and the longitudinal rolling brush 3 are installed, the axial direction of the transverse rolling brush 2 is perpendicular to the axial direction of the longitudinal rolling brush 3; at the same time, at least one transverse rolling brush 2 is arranged in each group. When the transverse rolling brushes 2 in each group are one, one transverse rolling brush 2 in the group is positioned at the bottom of the cage frame 1, and when the culture net cage enters and passes through the cage frame 1, one transverse rolling brush 2 in each group supports the culture net cage; when the transverse rolling brushes 2 in each group are a plurality of, the transverse rolling brushes 2 in the group are distributed at intervals along the circumferential direction of the cage frame 1, and when the culture net cage enters and passes through the cage frame 1, the transverse rolling brushes 2 in each group uniformly compress the circumferential direction of the culture net cage.

In the invention, after the transverse rolling brush 2 is installed, no matter whether the transverse rolling brush 2 in each group is one or a plurality of, the rolling surface of the transverse rolling brush 2 is always in friction fit with the outer wall of the culture net cage in the process of entering and passing through the cage frame 1, namely, the transverse rolling brush 2 can be driven to rotate through the friction fit between the outer wall of the culture net cage and the rolling surface of the transverse rolling brush 2 in the process of entering the cage frame 1, so that the transverse rolling brush 2 can play a role of guiding the culture net cage into the cage frame 1, reduce the friction between the culture net cage and the cleaning frame, not only can the culture net cage enter the cage frame 1 more smoothly, but also the culture net cage can pass through the cage frame 1 smoothly and be sent out of the cage frame 1, and the transverse rolling brush 2 can clean and scrape a certain amount of attachment such as shellfish and algae on the culture net cage in the rotating process.

Because the transverse rolling brush 2 can reduce the diameter of the passing space in the cage frame 1 when being arranged, and the structural strength of the culture net cage is smaller, the culture net cage can generate certain shrinkage when being radially extruded, so that the culture net cage can move more smoothly through friction between the transverse rolling brush 2 and the culture net cage in the process of entering and passing through the cage frame 1 after being installed, after the transverse rolling brush 2 is installed, the minimum diameter of the passing space formed by the rolling surfaces of a plurality of transverse rolling brushes 2 in the same group in a jointly surrounding way is slightly smaller than the outer diameter of the culture net cage, or the minimum diameter of the passing space formed by the rolling surface of one transverse rolling brush 2 in the same group and the inner wall of the cage frame 1 in a jointly surrounding way is slightly smaller than the outer diameter of the culture net cage.

It should be noted that, the passing space herein refers to a cylindrical space through which the cultivation net cage can pass; when the transverse rolling brushes 2 in the same group are multiple, the transverse rolling brushes 2 in the same group jointly surround to form a polygon, at the moment, the space is the inscribed circle of the polygon, when the transverse rolling brushes 2 are multiple groups, the inscribed circles of the polygon formed by the transverse rolling brushes 2 in each group jointly surround are equal in size, and the circle centers of the inscribed circles of the polygon formed by the transverse rolling brushes 2 in each group jointly surround are on the same straight line.

In order to facilitate the driving of the longitudinal roller brush 3, in the invention, the transverse roller brush 2 and the longitudinal roller brush 3 can be connected by adopting a gear transmission. The transverse rolling brush 2 is driven to rotate in the process of entering and passing through the cage frame 1, and the transverse rolling brush 2 is connected with the longitudinal rolling brush 3 through gear transmission, so that the longitudinal rolling brush 3 is driven to rotate in the process of entering and passing through the cage frame 1, and the longitudinal rolling brush 3 does not need to be driven to rotate through an additional power structure, so that the structure of the invention is simpler.

In the invention, because the central axis of the longitudinal rolling brush 3 and the central axis of the transverse rolling brush 2 are vertically arranged, when in actual installation, one end of the longitudinal rolling brush 3 and one end of the transverse rolling brush 2 are required to be arranged close to each other, bevel gears 7 are arranged at one end of the longitudinal rolling brush 3 and one end of the transverse rolling brush 2 which are close to each other, and the transmission of the transverse rolling brush 2 and the longitudinal rolling brush 3 is realized through the meshing of the two bevel gears 7. In order to meet the rotating speed of the culture net cage in the cage frame 1, the reduction ratio of the two bevel gears 7 meshed with each other can be adjusted by changing the corresponding gears, so that the cleaning efficiency of the cleaning head 4 on the culture net cage is changed, and the whole culture net cage is ensured to be cleaned.

In the invention, each longitudinal rolling brush 3 can be in transmission connection with one transverse rolling brush 2 in one group through one end, or the two ends of each longitudinal rolling brush 3 can be in transmission connection with one transverse rolling brush 2 in the two groups respectively; meanwhile, in order to satisfy the driving of the longitudinal roller brushes 3, the number of longitudinal roller brushes 3 in a group of longitudinal roller brushes 3 and a group of transverse roller brushes 2 located at adjacent positions is not greater than the number of transverse roller brushes 2 in the group.

Specifically, in the invention, the number of the longitudinal rolling brushes 3 is 2, the number of the transverse rolling brushes 2 is 3, the number of the longitudinal rolling brushes 3 in each group is 1, the longitudinal rolling brushes 3 in the two groups are arranged in a staggered manner, the number of the transverse rolling brushes 2 in one group positioned at the two ends of the cage frame 1 is 3, the number of the transverse rolling brushes 2 in one group positioned at the middle of the cage frame 1 is 2, one transverse rolling brush 2 positioned at the front end of the cage frame 1 is meshed with one longitudinal rolling brush 3 near the front end of the cage frame 1, and one transverse rolling brush 2 positioned at the rear end of the cage frame 1 is meshed with one longitudinal rolling brush 3 near the rear end of the cage frame 1.

In the invention, a plurality of cleaning heads 4 are arranged at intervals along the length direction of the cage frame 1, the axial distance between two adjacent cleaning heads 4 can be equal or unequal, and the specific axial distance between two adjacent cleaning heads 4 can be adjusted according to actual conditions. Because the culture net cage rotates while passing through the cage frame 1, and the position of the cleaning head 4 on the cage frame 1 is fixed, the path of the cleaning head 4 on the culture net cage is a spiral cleaning path when the culture net cage passes through the cage frame 1; according to the invention, the plurality of cleaning heads 4 arranged on the cage frame 1 are matched together, so that a plurality of cleaning paths can exist on the culture net cage at the same time in the process of passing through the cage frame 1, and the cleaning effect of the culture net cage is better through the plurality of cleaning paths matched together.

As shown in fig. 1 and fig. 2, in the present invention, when the plurality of cleaning heads 4 are arranged, the plurality of cleaning heads 4 may be arranged in a staggered manner, so that points where the plurality of cleaning heads 4 initially contact with the culture net cage are different in the process of passing through the cage frame 1, thereby ensuring that cleaning paths of the plurality of cleaning heads 4 on the culture net cage are not overlapped, ensuring that the plurality of cleaning heads 4 jointly clean the culture net cage, and ensuring that the cleaning of the culture net cage is more thorough. When the number of the cleaning heads 4 is plural, the cleaning heads 4 are uniformly distributed at intervals in the circumferential direction of the cage frame 1, so that the included angles of two adjacent cleaning heads 4 in the circumferential direction of the cage frame 1 are equal, for example, when the number of the cleaning heads 4 is 3, the 3 cleaning heads 4 are respectively positioned at 120 DEG, 240 DEG and 360 DEG in the circumferential direction of the cage frame 1; of course, when the number of the cleaning heads 4 in the invention is plural, the included angles of the two adjacent cleaning heads 4 in the circumferential direction of the cage frame 1 can be unequal, and the included angles of the two adjacent cleaning heads 4 in the circumferential direction of the cage frame 1 can be arranged at will under the condition of meeting the requirements of cleaning the culture net cage.

As shown in fig. 4,5 and 6, the cleaning head 4 includes a cleaning disc 401, the cleaning disc 401 is located inside the cage 1, the diameter direction of the cleaning disc 401 is consistent with the axial direction of the cage 1, and the cleaning disc 401 can rotate sufficiently relative to the cage 1; the cleaning disc 401 is further provided with a plurality of blades 403 and a plurality of high-pressure spray heads 402, the plurality of high-pressure spray heads 402 and the plurality of blades 403 are uniformly distributed at intervals along the circumferential direction of the cleaning disc 401, wherein when high-pressure water flows through the high-pressure spray heads 402, cavitation jet flows are formed inside the high-pressure spray heads 402 by the high-pressure water flows, a large amount of cavitation bubbles in the cavitation jet flow are broken to form crushing force for cleaning attachments on the aquaculture net cage, and the blades 403 crush and scrape attached organisms on the aquaculture net cage through the cleaning disc 401.

In order to prevent the high-pressure spray nozzle 402 from being directly hooked on the culture net cage under the condition that the blades 403 do not smash and scrape the attached organisms on the culture net cage in the rotating process of the cleaning disc 401, the height of the high-pressure spray nozzle 402 on the cleaning disc 401 is lower than that of the blades 403 on the cleaning sheet, so that the high-pressure spray nozzle 402 cannot be contacted with the culture net cage in the rotating process of the cleaning disc 401, and the culture net cage is prevented from being hooked by the high-pressure spray nozzle 402; meanwhile, in order to prevent the blade 403 from hooking on the culture net cage during the rotation of the cleaning disc 401, the cutting edge of the blade 403 can be set to be inclined, and the height of the cutting edge of the blade 403 on the cleaning disc 401 is gradually reduced based on the rotation direction of the cleaning disc 401, so that the cutting edge of the blade 403 can not damage the culture net cage when the attached organism on the culture net cage is smashed and scraped during the rotation of the cleaning disc 401. In order to make the edge of the blade 403 smoother, the edge of the blade 403 is in arc transition with two sides of the blade 403, so that the blade 403 is prevented from hooking the culture net cage as much as possible.

In order to drive the cleaning disc 401, the plurality of high-pressure nozzles 402 may be uniformly arranged at intervals along the circumferential direction of the cleaning disc 401, and when the high-pressure nozzles 402 are installed, the outlet ends of the plurality of high-pressure nozzles 402 are inclined toward the same circumferential direction of the cleaning disc 401, and it should be noted that the inclination of the high-pressure nozzles 402 is not inclined toward the radial direction of the cleaning disc 401, but inclined in the tangential direction of the ring formed by the plurality of high-pressure nozzles 402. Because the high-pressure spray heads 402 are fixed on the cleaning disc 401, and the high-pressure water flow can apply a reverse acting force to the high-pressure spray heads 402 when being sprayed, the reverse acting force received by the high-pressure spray heads 402 inclines along the tangential direction of the circular ring formed by the high-pressure spray heads 402 around the circular ring, and therefore, when the high-pressure spray heads 402 spray the high-pressure water flow at the same time through the cooperation of the high-pressure spray heads 402, the reverse acting force received by the high-pressure spray heads 402 acts on the cleaning disc 401 together, so that the cleaning disc 401 can fully rotate on the cage frame 1, and the cleaning disc 401 can be driven without an additional power structure, so that the cleaning disc 401 can be driven more simply; meanwhile, by rotating the cleaning disc 401, the blades 403 on the cleaning disc 401 synchronously rotate, so that the blades 403 are ensured to break and scrape the attached organisms on the culture net cage.

In order to prevent the blade 403 from hooking the cutting edge of the blade 403 into an inclined shape in the process of crushing and scraping the organisms attached to the culture net cage, the invention ensures that the inclined direction of the inclined edge of the blade 403 is consistent with that of the blade 403 when the cleaning disc 401 rotates, and particularly, the low end of the high-pressure nozzle 402 and the low end of the cutting edge of the blade 403 are positioned on the same side, wherein the low end of the cutting edge of the blade 403 is the end of the blade 403 with higher height on the cleaning disc 401, and the high end of the cutting edge of the blade 403 is the end of the cutting edge of the blade 403 with lower height on the cleaning disc 401, so that the height of the blade 403 on the cleaning disc 401 is gradually reduced based on the rotating direction of the cleaning disc 401 when the high-pressure water reaction of the plurality of high-pressure nozzles 402 drives the cleaning disc 401 to rotate, thereby preventing the blade 403 from hooking the high end of the organisms attached to the culture net cage on the scraping and scraping the culture net cage.

The included angle between the high-pressure spray head 402 and the cleaning disc 401 is 30 degrees, and the specific angle between the high-pressure spray head 402 and the cleaning disc 401 can be adjusted according to practical situations.

Because the surface of the culture net cage is uneven, in order to ensure that the cleaning head 4 is always abutted against the surface of the cage frame 1 in the process of passing through the cage frame 1, an elastic seat is required to be installed on the cage frame 1 when the cleaning head 4 is installed, and the elastic direction of the elastic seat is consistent with the radial direction of the cage frame 1; meanwhile, the elastic seat is also provided with a rotary joint 11, the rotary joint 11 is directly used in the prior art, the outer wall of the rotary joint 11 is provided with a water inlet for pipeline connection, the inner pipe of the rotary joint 11 is used as a water outlet, and the extending end of the inner pipe of the rotary joint 11 is connected with a structure for rotary motion.

In the invention, the high-pressure spray heads 402 are fixed on the cleaning disc 401, and the high-pressure spray heads 402 and the rotating disc are required to rotate, so that the rotating disc is directly fixed on the extending end of the inner tube of the rotating joint 11 during installation, and the extending end of the inner tube of the rotating joint 11 is respectively communicated with the plurality of high-pressure spray heads 402 through pipelines, thereby not only ensuring that high-pressure water flows are conveyed to each high-pressure spray head 402, but also ensuring that the cleaning disc 401 can sufficiently rotate relative to the cage frame 1.

When the culture net cage is in the process of passing through the cage frame 1, the elastic seat can move to the outer wall of the culture net cage through the elastic rotary joint 11 of the elastic seat and the cleaning head 4 arranged on the inner pipe of the rotary joint 11, so that the cleaning head 4 is always abutted against the surface of the culture net cage, the close cleaning of the culture net cage is realized, and the cleaning effect of the culture net cage is ensured.

The cleaning disc 401 is in a cap shape, at this time, the high-pressure spray head 402 is fixed on the inner top of the cleaning disc 401, and the blade 403 is fixedly arranged on the edge of the cleaning disc 401 through a screw; meanwhile, in order to reduce the weight of the cleaning disc 401, the top surface of the cleaning disc 401 may be omitted, and then staggered connecting rods may be installed in the cleaning disc 401, in which case the high-pressure nozzle 402 may be fixed on the connecting rods, and the staggered centers of the plurality of connecting rods may be fixed on the extending ends of the inner tubes of the rotary joints 11.

As shown in fig. 4 and 5, the elastic seat includes a fixed shaft 8 fixed on a rotary joint 11, the central axis of the fixed shaft 8 is on the same line with the central axis of the rotary joint 11, and the housing of the rotary joint 11 does not rotate, so that the fixed shaft 8 does not rotate after being mounted on the rotary joint 11; the cage frame 1 is also provided with a mounting hole in clearance fit with the fixed shaft 8, one end of the fixed shaft 8 far away from the rotary joint 11 extends outwards through the mounting hole, the extending end of the fixed shaft 8 is provided with a limiting disc 9, and the diameter of the limiting disc 9 is larger than that of the mounting hole on the cage frame 1, so that the fixed shaft 8 is prevented from falling off from the cage frame 1 directly; the fixed shaft 8 is also sleeved with a compression spring 10, one end of the compression spring 10 is abutted against the inner wall of the cage frame 1, and the other end of the compression spring 10 is abutted against the rotary joint 11.
