Description

Technical Field

[0001] This utility model belongs to the field of aquaculture pond cleaning technology, and specifically relates to an aquaculture pond manure suction device. Background Technology

[0002] During aquaculture, fish, shrimp, and other aquatic products continuously produce large amounts of feces and uneaten feed sediment. If these organic wastes are not removed in time, they will decompose in the anaerobic environment at the bottom of the pond, releasing toxic substances such as ammonia nitrogen, nitrite, and hydrogen sulfide. This leads to a decrease in dissolved oxygen in the aquaculture water and the proliferation of pathogenic microorganisms, directly threatening the survival rate and growth quality of aquatic organisms.

[0003] Aquaculture ponds typically feature a water circulation and filtration system. Its working principle is as follows: a suction head is fixed to the bottom of the pond or suspended below a float with the suction end facing downwards. The suction head is connected to a water pump via an inlet pipe. The negative pressure generated by the pump forces the aquaculture water, carrying feces, through the suction head into a delivery pipe. Finally, the water is transported to a filtration device for solid-liquid separation, and then the filtered water is returned to the aquaculture pond. However, during the aquaculture process, feces still accumulate at the bottom of the pond. If not cleaned promptly, the feces will adhere to the bottom, making it difficult to remove them solely through the fluid shear force generated by the negative hydraulic pressure.

[0004] Therefore, how to conveniently and efficiently clean the stubborn feces at the bottom of the pool is a problem that needs to be solved. Utility Model Content

[0005] This utility model provides a manure suction device for aquaculture ponds, which can conveniently and effectively clean stubborn manure accumulated at the bottom of aquaculture ponds.

Detailed Implementation

[0023] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0024] See Figures 1 to 4 This utility model provides a manure suction device for aquaculture ponds, including a counterweight 17 and a water pump 16. The top of the counterweight 17 is hinged to a connector 15, and multiple sections 2 are sequentially and detachably connected to the connector 15 to facilitate adjustment of the length of the hand-held push of the counterweight 17. The lower surface of the counterweight 17 is provided with a water suction trough 19 and four rollers 21. Two rollers 21 are located on the front side of the water suction trough 19 and two rollers 21 are located on the rear side of the water suction trough 19. The bottom of the water suction trough 19 is provided with a baffle 20, which can prevent aquatic products from being sucked in and can also allow manure to be sucked in. The baffle 20 is provided with multiple brushes 18. When the rollers 21 are supported on the bottom of the pond, the lower end of the brushes 18 contacts the bottom of the pond and can sweep the bottom of the pond. The water pump 16 is located inside the counterweight 17. The water inlet end of the water pump 16 is connected to the top of the water suction trough 19, and the water outlet end of the water pump 16 is connected to a drain pipe 1. The drain pipe 1 is a flexible hose and is connected to a filter assembly.

[0025] When the bottom of the pond needs to be cleaned, by connecting an appropriate number of sections 2 to the connector 15, the counterweight 17 is placed in the pond. After starting the water pump 16, the water suction trough 19 is directed towards the bottom of the pond to draw water. During this process, the sections 2 push the counterweight 17 back and forth to drive the roller 21 to roll back and forth on the bottom of the pond. The counterweight 17 drives the brush 18 to sweep back and forth on the bottom of the pond, brushing up the stubborn feces that are stuck to the bottom of the pond. This allows the aquaculture water to carry the feces through the baffle 20 into the water tank and then into the water pump 16. The feces are then transported to the filter assembly through the drain pipe 1 for filtration. This method can conveniently and effectively clean the stubborn feces at the bottom of the aquaculture pond.

[0026] Preferably, the filter assembly includes a filter box 9 and a filter screen 7. The top of the filter box 9 is provided with a drain outlet 8. A float 5 is fitted on the outer wall of the filter box 9. The side wall of the filter box 9 is provided with a connecting cavity 12 with an annular cross-section. Multiple tangentially arranged nozzles 6 are spaced apart on the upper side of the inner wall of the connecting cavity 12. The drain pipe 1 is connected to the lower side of the connecting cavity 12. The filter screen 7 is located inside the filter box 9 and above the nozzles 6.

[0027] During the filtration process, the filter box 9 can be placed in the aquaculture pond. The float 5 will drive the filter box 9 to float on the water surface. After the drain pipe 1 delivers the aquaculture water into the connecting cavity 12, the aquaculture water is sprayed tangentially into the filter box 9 through multiple nozzles 6. The aquaculture water rotates in the filter box 9 to generate centrifugal force. The aquaculture water is treated by centrifugation and gravity, which helps the feces settle at the bottom of the filter box 9 and reduces the filtration load of the filter screen 7. After centrifugation, the aquaculture water flows upward through the filter screen 7, which uses the filter screen 7 to block other feces in the aquaculture water. The filtered aquaculture water is discharged back into the aquaculture pond through the drain outlet 8.

[0028] Preferably, the bottom of the filter box 9 is provided with a conical protrusion 11, and the filter box 9 is provided with a guide pipe 14. The upper end of the guide pipe 14 expands radially and connects between the filter screen 7 and the nozzle 6 on the inner wall of the filter box 9. The lower end of the guide pipe 14 has a trumpet-shaped structure and covers the upper part of the conical protrusion 11 with a preset gap.

[0029] During the centrifugation process of the aquaculture water, the aquaculture water first flows downward in a rotating manner under the combined action of the guide pipe 14 and the nozzle 6, and then flows upward towards the center with a decreasing rotation radius. As the rotation radius decreases, the centrifugal force increases, which makes the heavier feces more likely to move outward. This is conducive to separating the feces from the upward flowing aquaculture water and promoting the sedimentation of the feces in the aquaculture water to the bottom of the filter box 9. The aquaculture water flows upward through the guide pipe 14 and passes through the filter screen 7.

[0030] Preferably, a valve 10 is provided on the side wall of the filter box 9 near its bottom, and opening the valve 10 can discharge the dirt in the filter box 9.

[0031] Preferably, the drain pipe 1 is a flexible hose, and the drain pipe 1 is connected to the connecting cavity 12 through a quick connector 13. The quick connector 13 includes a male connector 15 and a female connector 15. The male connector 15 is disposed on the drain pipe 1, and the female connector 15 is connected to the connecting cavity 12 and disposed on the side wall of the filter box 9 near its bottom.

[0032] It is convenient to remove the drain pipe 1 from the filter box 9. When it is not necessary to filter the aquaculture water or to transport the aquaculture water to other filtration devices, the drain pipe 1 can be extended through the male connector 15 to transport the aquaculture water.

[0033] Preferably, the two ends of the section rod 2 are respectively provided with an internal threaded hole 4 and an external threaded head 3. After the external threaded head 3 of one section rod 2 is rotated into the internal threaded hole 4 of another section rod 2, it is convenient to realize the quick assembly and disassembly between the two adjacent sections rod 2. The end of the connector 15 is also provided with an internal threaded hole 4. The external threaded head 3 of the section rod 2 can be screwed into the internal threaded hole 4 of the connector 15, realizing the quick assembly and disassembly between the connector 15 and the section rod 2.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
