Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, and more specifically to a fish breeding device. Background Art

[0002] Cage culture is a very common breeding method. Through cage culture, the growth status of fish can be observed more carefully. At the same time, there is no need to salvage the fish in the later stage, which provides great convenience.

[0003] Current fish farming devices, for example, a novel cage fish farming device proposed in publication number: CN220174178U, the utility model adds a fastening nut, a connecting plate, a filter screen and a collecting box. The design allows the fish feces to pass through the filter screen and fall into the collecting box, thereby improving the growth environment of the fish and being beneficial to the growth of the fish. This solves the problem that the original cage device is hollow, the fish feces directly seeps into the pond after passing through the cage, and the growth environment of the fish is poor and is not conducive to the growth of the fish.

[0004] Although the existing fish breeding devices solve some problems of the growth environment when in use, it is found during use that the installation height of the existing fish breeding devices is fixed, and the water level of the river is affected by seasonal changes, so that the water level will change. When the water level exceeds the cage mouth, it is easy for the fish to escape from the cage. When the water level is low, it is easy for the fish to be exposed to the water surface, resulting in the death of the fish. Therefore, when the water level changes, the staff needs to readjust the height of the breeding device, which is time-consuming and laborious. The height of the breeding device cannot be adjusted quickly, which is inconvenient to use.

[0005] Therefore, how to provide a fish culture device that can adapt to water level changes is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the utility model provides a fish breeding device, which can drive the net cage to automatically adjust the height when the water level rises or falls, saving time and labor, and effectively improving the practicability of the fish breeding device.

The net box 3 is mounted on the floating board 1 through the box frame 9, and the net box 3 is detachably connected to the floating board 1 through a quick disassembly mechanism.

[0032] When fish are cultured through the net cage 3, the water quality is monitored by the water quality detector 4, and the guide rod 6 is supported by the tightening screw 8 to prevent the floating board 1 and the net cage 3 from shaking up and down due to waves. When the water level rises or falls and the height of the net cage 3 needs to be adjusted, the tightening screw 8 is loosened, and the floating board 1 floats on the water surface. The net cage 3 is installed on the floating board 1, so that when the water level rises or falls, the net cage 3 can be driven to automatically adjust its height, which saves time and effort and effectively improves the practicality of the fish culture device.

[0033] The guide rod 6 is in the shape of a rectangular column, and the outer dimensions of the guide rod 6 match the inner dimensions of the guide rod hole 5. The insertion rod 7 is fixedly connected to the guide rod 6 by welding, and the bottom end of the insertion rod 7 is tapered. The guide rod 6 is fixedly connected to the bottom of the water through the insertion rod 7. The floating board 1 is supported by the guide rod 6 to prevent the floating board 1 from floating randomly. When the floating board 1 rises or falls due to the rise and fall of the water level, the guide structure formed by the guide rod 6 and the guide rod hole 5 can guide the rise and fall of the floating board 1 to prevent the rise and fall of the floating board 1 from being offset.

[0034] The quick disassembly and assembly mechanism includes a support 10, which is arranged on the floating board 1 at the outer edge of the box frame 9. The top of the support 10 is rotatably connected to a pressure rod 11. An installation box 19 is arranged in the support 10, and an installation hole 20 is arranged on the top of the installation box 19. A rotating block 12 is installed in the installation box 19, and the rotating block 12 is connected to the pressure rod 11 through a connecting rod 21. The ring side of the rotating block 12 is equidistantly fixedly connected with the first locking tooth 13, the side wall of the installation box 19 is provided with a spring groove 14, a spring 15 is installed in the spring groove 14, a baffle 16 is installed on the side of the spring 15 close to the rotating block 12, the side of the baffle 16 away from the spring 15 is equidistantly fixedly connected with the second locking tooth 17, the side of the baffle 16 away from the second locking tooth 17 is fixedly connected with a pull rod 18, the end of the pull rod 18 away from the baffle 16 passes through the interior of the support 10 and extends to the outside, the tooth pitch of the first locking tooth 13 is equal to the tooth pitch of the second locking tooth 17, and the second locking tooth 17 is elastically connected to the support 10 through the spring 15. When the net box 3 needs to be installed, The net box 3 is passed through the box opening 2 and is placed above the floating board 1 through the box frame 9. Then, the second locking tooth 17 is driven by the pull rod 18 to overcome the elastic force of the spring 15 and move away from the first locking tooth 13, so that the pressure rod 11 can rotate. The pressure rod 11 is rotated to the top of the box frame 9 to fix the net box 3 and the floating board 1. When the pull rod 18 is released, the second locking tooth 17 is pressed against the first locking tooth 13 through the spring 15. The rotating block 12 is fixed by the engagement of the second locking tooth 17 with the first locking tooth 13, and then the pressure rod 11 is fixed to prevent the pressure rod 11 from rotating at will. When disassembly is required, the pressure rod 11 can be rotated away from the top of the box frame 9.

[0035] Working principle: This fish breeding device for water quality detection monitors the water quality through the water quality detector 4 when breeding fish through the net cage 3, and uses the fastening screw 8 to resist the guide rod 6 to prevent the water waves from driving the floating board 1 and the net cage 3 to shake up and down. When the water level rises or falls and the height of the net cage 3 needs to be adjusted, the fastening screw 8 is loosened, and the floating board 1 floats on the water surface.

The guide rod 6 is fixedly connected to the bottom of the water through the insertion rod 7, and the floating board 1 is supported by the guide rod 6 to prevent the floating board 1 from floating randomly. When the floating board 1 rises or falls due to the rise and fall of the water level, the guide structure formed by the guide rod 6 and the guide rod hole 5 can guide the lifting of the floating board 1 to prevent the lifting of the floating board 1 from deviation.

[0036] When the net box 3 needs to be installed, the net box 3 is passed through the box opening 2 and is placed above the floating board 1 through the box frame 9. Then, the second locking tooth 17 is driven by the pull rod 18 to overcome the elastic force of the spring 15 and move away from the first locking tooth 13, so that the pressure rod 11 can rotate. The pressure rod 11 is rotated to the top of the box frame 9 to fix the net box 3 and the floating board 1. When the pull rod 18 is released, the second locking tooth 17 is pressed against the first locking tooth 13 through the spring 15. The rotating block 12 is fixed by the engagement of the second locking tooth 17 with the first locking tooth 13, and then the pressure rod 11 is fixed to prevent the pressure rod 11 from rotating at will. When disassembly is required, the pressure rod 11 can be rotated away from the top of the box frame 9.
