Description

Technical Field

[0001] The utility model relates to the technical field of fish breeding, in particular to a sewage discharge device for a fish breeding pond. Background Art

[0002] Fish breeding ponds need to be discharged because during the fish breeding process, fish will produce a large amount of feces, and fish feed will also produce certain residues during the breeding process. These fish feces and feed residues accumulate in the fish pond, which will cause the water quality to deteriorate, the water body to become eutrophic, and the water ecological balance to be destroyed.

[0003] When some wild aquatic products, especially alien species of fish, are artificially cultivated, it is generally not allowed to use open-air fish ponds. This is mainly to prevent the impact of species invasion, so special artificially constructed breeding ponds are needed.

[0004] Conventional sewage discharge methods for fish breeding ponds are to set the bottom wall of the breeding ground to be reversible, and regularly clean and reverse the bottom. However, this technical method cannot be fully applied to all fish breeding ponds. When breeding wild aquatic products, it is necessary to simulate the natural ecological environment as much as possible, including aquatic vegetation and bottom sediments, etc. Therefore, when using conventional sewage discharge methods, it is impossible to absorb the fish feces accumulated on the upper surface of the bottom sediment laid at the bottom of the breeding pond. In order to solve this technical problem, the utility model proposes a sewage discharge device for fish breeding ponds. Utility Model Content

Rotating the knob can drive the support frame 1 to move up and down as a whole, so that it can be freely adjusted according to the thickness of different bottom materials, and the motor 5 can drive the sewage suction pipe 6 to move, and the suction The outside of the sewage pipe 6 is connected to a water pump, which can pump water through the sewage suction pipe 6 horizontally downward in the range of 180° to 230°, and the sewage suction pipe 6 can stir the bottom surface when moving, so that the fish feces accumulated on the bottom surface can be dispersed into the water, and then will be sucked away by the sewage suction pipe 6. The whole process will neither affect the normal life of the middle and upper layer fish nor cause major damage to the bottom as a whole, and can also effectively absorb the feces accumulated on the bottom, thereby effectively solving the problem that conventional sewage discharge means cannot absorb the fish feces accumulated on the upper surface of the bottom laid at the bottom of the breeding pond.

[0024] Both ends of the sewage suction pipe 6 are fixedly connected with a fixed seat 7, the outer surface of the fixed seat 7 is slidably connected to the outer surface of the support frame 1, the inner surface of the support frame 1 is fixedly connected with a slide rod 8, the outer surface of the slide rod 8 is slidably connected to the inner wall of the support frame 1, and the slide rod 8 can assist the fixed seat 7 to move in a directional manner, so that the fixed seat 7 can drive the sewage suction pipe 6 to move without displacement or misalignment, making the overall equipment more stable when in use.

[0025] The output end of the motor 5 is fixedly connected to a driving rod 9, the other end of the driving rod 9 is rotatably connected to the inner surface of the support frame 1, the outer surface of the driving rod 9 is threadedly connected to the inner wall of the fixed seat 7, the motor 5 can drive the driving rod 9 to rotate, and threads with opposite screw directions are arranged from both ends of the driving rod 9 to the center point. When the driving rod 9 rotates, the fixed seat 7 can drive the two sewage suction pipes 6 to move simultaneously in opposite directions to each other, and the moving speeds are the same.

[0026] The outer surface of the sewage suction pipe 6 is fixedly connected to a mounting frame 18, and a plow 10 is fixedly mounted on the bottom surface of the mounting frame 18. The mounting frame 18 can provide support for the plow 10. When the sewage suction pipe 6 moves, the plow 10 can be driven to move by the mounting frame 18.
