Description

Technical Field

[0001] The present invention relates to the field of aquaculture, and more particularly, to a dead fish collection device for deep - water aquaculture cages. Background Art

[0002] Deep - sea cages mainly consist of a frame system, a net bag, a fixing system, and supporting facilities. By utilizing the interaction of the fixing platform and the characteristics of the cage body, the cage body is lowered to a specified depth underwater. Since the wave intensity decays exponentially with the increase in water depth, the wave intensity at the location of the cage at a certain depth will also decrease exponentially, so as to achieve the purpose of resisting wind and waves.

[0003] Due to the large number of fish cultured in the cage, when dead fish appear in the cage, the rotten dead fish will affect the live fish in the cage, and it is necessary for the staff to handle them in time. However, because the cage is large in volume and located above the sea surface, at present, manual salvage can only salvage the dead fish and diseased fish floating on the water surface, and it is very difficult to salvage the dead fish and diseased fish at the bottom of the water. Therefore, it often causes incomplete salvage of dead fish and diseased fish, resulting in water pollution and disease transmission. Summary of the Invention

[0004] The main object of the present invention is to provide a dead fish collection device for deep - water aquaculture cages. Through the cooperation of a guiding pipe and a synchronous belt, it can continuously collect and process the dead fish at the bottom and top of the cage, avoiding the influence of dead fish on the inside of the cage.

[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0032] See Figures 1 to 10As shown, a dead fish collecting device for deep-water aquaculture cages comprises a cage 1, a guide tube 2, a collecting mechanism 3 and a traction mechanism 4; horizontal plates 11 are mirror-imaged on both sides of the top of the cage 1, a fixing hole 12 is arranged at the center of each horizontal plate 11, there are two guide tubes 2, the guide tubes 2 are arranged in the corresponding fixing holes 12 in a vertical state, and two groups of collecting mechanisms 3 are arranged on the outer wall of each guide tube 2 along the axial direction, and the two groups of collecting mechanisms 3 are respectively used to collect dead fish on the water surface and the bottom of the water; each group of collecting mechanisms 3 comprises a collar 31 and a 匚-shaped mounting plate 32; the collar 31 is coaxially rotatably arranged on the outside of the corresponding guide tube 2, an annular accommodating groove 311 is arranged inside the collar 31, and a plurality of collecting grooves 21 connected with the annular accommodating groove 311 are arranged on the outer wall of each guide tube 2 along the circumferential direction of the axis; a plurality of 匚-shaped mounting plates 32 are arranged on the outer wall of the collar 31 circumferentially, and the length direction of each 匚-shaped mounting plate 32 is toward the center of the corresponding collar 31 A plurality of connecting grooves 312 are circumferentially arranged on the outer wall of the collar 31 and connected to the corresponding 匚-shaped mounting plates 32; two connecting shafts 321 are rotatably arranged inside each 匚-shaped mounting plate 32, and the two connecting shafts 321 can rotate synchronously with the rotation of the collar 31, and the two connecting shafts 321 are connected through a synchronous belt 322 for transmission, and a plurality of connecting strips 323 are equidistantly arranged on each synchronous belt 322, and a hinge groove 3231 is arranged at the center of each connecting strip 323, and a connecting rod 324 is hinged in each hinge groove 3231, and a partition plate 3241 is arranged at the center of each connecting rod 324, and a centering torsion spring 3242 is arranged at both ends of each connecting rod 324; a recovery filter disc 22 is slidably arranged inside the guide tube 2, and a discharge groove 23 is arranged on the outer wall at the top of the guide tube 2, and a traction mechanism 4 is arranged at the top of the guide tube 2 and is used to make the recovery filter disc 22 move back and forth along the axial direction of the guide tube 2.

[0033] The cage 1 is pulled to the corresponding area in the water by a tugboat and lowered to a specified depth underwater. A pedestrian passage is provided on the top of the cage 1, so that the staff can manage the fish in the cage 1 conveniently. When dead fish appear in the cage 1, due to the different death times of the fish, when the fish just dies, its body may float on the water surface due to the decrease in specific gravity. However, as time goes by and bacteria decompose the fish tissues, the gas and water in the fish body will increase, causing the specific gravity of the fish to further decrease, and eventually it will sink into the water. At this time, there may be dead fish both at the bottom and on the surface of the cage 1.

[0034] Thus, after the cage 1 sinks to the corresponding position, the positions of the two collars 31 on the guide pipe 2 are adjusted so that the upper collar 31 is exactly below the water surface and the lower collar 31 is at the bottom of the cage 1; when collecting dead fish, by rotating the collar 31, the collar 31 can slowly rotate along the axis of the guide pipe 2, so that the U-shaped mounting plate 32 on the outer wall of the collar 31 can rotate slowly synchronously, thereby contacting the dead fish on the water surface and the corresponding bottom of the cage 1. The dead fish can contact the synchronous belt 322 inside the U-shaped mounting plate 32. A plurality of connecting strips 323 are provided on the synchronous belt 322. Under the torsion of the central torsion spring 3242, each partition plate 3241 is arranged in a vertical state. A space for limiting the dead fish is formed between two adjacent partition plates 3241 and the inner walls on both sides of the corresponding U-shaped mounting plate 32; and as the collar 31 rotates, the two connecting shafts 321 can rotate synchronously, so that the synchronous belt 322 can rotate, pushing the dead fish towards the inside of the collar 31. And due to the arrangement of the partition plate 3241, it can not only limit the position of the dead fish, but also contact the accidentally entered live fish, so that the live fish can be disturbed and prevented from entering the inside of the collar 31; when the dead fish enter the annular receiving groove 311 of the corresponding collar 31, as the collar 31 continues to rotate, the partition plate 3241 also rotates with the rotation of the synchronous belt 322, and the partition plate 3241 can contact the outer wall of the guide pipe 2, so that the dead fish can enter the inside of the guide pipe 2 through the collection groove 21 on the outer wall of the guide pipe 2, thus completing the collection of the dead fish. And the rotating U-shaped mounting plate 32 can disturb the live fish in the cage 1, so as to ensure the activity of the live fish in the cage 1; after the collection is completed, the collar 31 stops rotating, and the recovery filter disk 22 is pulled by the traction mechanism 4 so that the recovery filter disk 22 can move towards the top of the guide pipe 2, thereby contacting the dead fish entering the inside of the guide pipe 2, so that the recovery filter disk 22 can move to the discharge groove 23, and the staff can perform secondary treatment on the dead fish through the discharge groove 23, thus avoiding the pollution of the live fish in the cage 1 by the dead fish and ensuring the survival rate of the cage 1 culture.

[0035] See Figure 5 and Figure 8 As shown, a driven gear 325 is provided on the connecting shaft 321 near the corresponding collar 31 inside each U-shaped mounting plate 32. Two driving gear rings 24 are arranged on the outer wall of the guide pipe 2 along the axial direction. The driving gears are located inside the corresponding collars 31, and the driving gears are meshed with the corresponding driven gears 325.

[0036] A driven gear 325 is provided on each connecting shaft 321 near the collar 31. The driven gear 325 meshes with the driving tooth ring 24 on the outer wall of the guide pipe 2. As the collar 31 rotates, the driven gear 325 can rotate under the cooperation of the driving gear, so that the synchronous belt 322 can rotate, and thus dead fish can be continuously pushed into the guide pipe 2.

[0037] See Figure 4 As shown, a horizontal ring 25 is further provided at the lower end of the guide pipe 2. A submersible pump 26 is provided inside the horizontal ring 25, and the recovery and filtration disc 22 is located above the submersible pump 26.

[0038] In order to better collect dead fish, a horizontal ring 25 is provided at the lower end of the guide pipe 2. A submersible pump 26 is provided inside the horizontal ring 25. The horizontal ring 25 is hermetically connected to the outer wall of the submersible pump 26. The submersible pump 26 is arranged vertically. The input end of the submersible pump 26 is vertically upward, and the output end of the submersible pump 26 is vertically downward. The recovery and filtration disc 22 is located above the submersible pump 26. While the collar 31 rotates, the submersible pump 26 operates to suck the water inside the guide pipe 2, and suck the water through the collection groove 21 on the outer wall of the guide pipe 2 and the communication groove 312 on the outer wall of the collar 31, so as to guide the dead fish in the net cage 1 and prevent the dead fish from "sticking to the edge" and being omitted; and during the suction process of the submersible pump 26, it can secondarily guide the dead fish entering the inside of the collar 31, so as to ensure that the dead fish can enter the guide pipe 2 and be located above the recovery and filtration disc 22, avoiding the accumulation of dead fish in the collar 31; secondly, the water body sucked by the submersible pump 26 can be quickly discharged from the net cage 1 through the lower end of the guide pipe 2, so as to accelerate the replacement of the water body inside the net cage 1 and improve the survival rate of fish.

[0039] See Figure 5 and Figure 10 As shown, two inclined plates 326 are mirror-symmetrically arranged on one side of each C-shaped mounting plate 32 along the length direction, and the two inclined plates 326 are arranged at an obtuse angle.

[0040] Two inclined plates 326 are provided on each C-shaped mounting plate 32. As the collar 31 rotates, the two inclined plates 326 can increase the interception area of the C-shaped mounting plate 32, so as to better collect dead fish.

[0041] See Figure 8 and Figure 9 As shown, a plurality of water passing grooves 3243 are provided on each partition plate 3241.

[0042] In order to prevent the partition plate 3241 from contacting water during movement, which may cause water flow and make the dead fish shake, multiple water troughs 3243 are provided on the partition plate 3241, enabling water to flow through the water troughs 3243, reducing the water fluctuations generated, and ensuring the stability of dead fish transportation. Similarly, the synchronous belt 322 is preferably a chain conveyor belt, which can further reduce water flow.

[0043] See Figure 1 、 Figure 5 and Figure 6 As shown in

[0044] the traction mechanism 4 includes a traction shaft 41 and a traction motor 42. The traction shaft 41 is rotatably arranged inside the corresponding guide pipe 2 and above the horizontal plate 11. The traction motor 42 is arranged on the guide pipe 2 and is used to drive the traction shaft 41 to rotate. A winding wheel 411 is arranged at the center of the traction shaft 41, and a traction rope 412 is arranged on the winding wheel 411. One end of the traction rope 412 away from the winding wheel 411 is connected to the center of the corresponding recovery and filtration disk 22.

[0045] See Figure 1 and Figure 5 As shown in

[0046] each bottom of the horizontal plate 11 is rotatably provided with a rotating gear 111, each guide pipe 2 is rotatably provided with a driven gear ring 27, and a driving motor 112 for driving the rotating gear 111 to rotate is further arranged on the horizontal plate 11. Multiple vertical rods 313 are connected between the driven gear ring 27 and the corresponding two collar rings 31.

[0047] See Figure 1 As shown in

[0048] By providing the railing 113, the safety of the staff can be ensured when the staff processes the dead fish.
