Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a sludge suction device for a land-based cylindrical aquaculture pond for giant spiny loach. Background Technology

[0002] With the maturation of artificial breeding technology for giant spiny loach, people have begun to try breeding them in land-based aquaculture ponds. Compared with traditional fish ponds, land-based aquaculture ponds can achieve an intensive breeding model, saving land, water resources, and costs. They also allow for better water quality control and enhanced disease prevention. During the breeding process, leftover fish food, feces, and other debris easily accumulate at the bottom of the pond. Giant spiny loach are bottom-dwelling fish and lack a swim bladder, so diseased or recently deceased fish do not float to the surface, making disease outbreaks difficult to detect. Therefore, people have designed devices that can suck up dead fish. For example, Chinese Patent Application No. 202022035621.7 discloses an energy-saving fish pond that can automatically and quickly drain sewage and clean up dead fish. This includes a pond bottom, pond side walls, a dead fish cleaning device, and a rapid discharge and overflow prevention mechanism. The dead fish cleaning device is equipped with an anti-clogging component. This device utilizes the principle that the bottom of the cleaning tray is lower than the water surface. Water flows into the cleaning tray from the suction pipe according to the principle of communicating vessels. The water in the cleaning tray is then pumped out through the drain pipe, allowing water to continuously flow into the cleaning tray from the suction pipe. This sucks the dead and diseased fish at the bottom into the cleaning tray. However, the water flow speed in the suction pipe of this structure depends on the height difference between the upper part of the suction pipe and the water surface. Since the height difference is usually only 10cm to 20cm, the water flow speed in the suction pipe is relatively low, resulting in limited suction for dead fish at the bottom. Therefore, a suction device for land-based cylindrical tank culture ponds of giant spiny loach is needed. This device can generate greater suction through a sealed collection box, thereby better sucking the sludge and dead and diseased fish at the bottom of the culture pond into the collection box, preventing the rotting of dead and diseased fish from affecting water quality. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes a sludge suction device for a land-based cylindrical aquaculture pond for giant spiny loach. This device can generate greater suction through a sealed collection box, thereby better drawing sludge and diseased or dead fish from the bottom of the pond into the collection box, preventing the rotting of diseased or dead fish from affecting water quality.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a sludge suction device for a land-based cylindrical aquaculture pond of giant spiny loach, comprising: an aquaculture pond, a first sludge suction pipe, a second sludge suction pipe, a collection box, a third sludge suction pipe, and a filter. The bottom of the aquaculture pond is inverted conical. One end of the first sludge suction pipe is connected to the filter, and the other end extends to the lowest point of the bottom of the aquaculture pond. One end of the second sludge suction pipe is connected to the filter, and the other end is connected to the inner cavity of the collection box. The bottom of the collection box is 20cm to 30cm lower than the water level of the aquaculture pond. One end of the third sludge suction pipe is connected to the bottom of the collection box, and the other end extends to the bottom of the aquaculture pond. The extension end of the third sludge suction pipe is spaced 30cm to 60cm from the first sludge suction pipe. The upper part of the collection box is provided with a sealing cover, which covers the upper opening of the collection box and is connected to the collection box by a locking buckle.

[0006] Furthermore, the lower part of the sealing cover is provided with a limiting groove, and a rubber gasket is provided in the limiting groove. The sealing cover is connected to the upper edge of the collection box through the limiting groove.

[0007] Furthermore, the sealing cap is made of transparent plastic.

[0008] Furthermore, the lower end of the latch is hinged to the collection box, the upper part of the latch is provided with a sleeve, and the upper edge of the sealing cover is provided with a limiting strip. The latch is pressed tightly against the upper part of the sealing cover through the sleeve, and the limiting strip blocks both sides of the sleeve.

[0009] Furthermore, a main return water pipe is provided around the aquaculture pond, the filter is connected to the main return water pipe via a water pump, and the main return water pipe is connected to the interior of the aquaculture pond via multiple branch return water pipes.

[0010] Furthermore, both the first and second suction pipes are equipped with filter screens at their ends, and the extension end of the third suction pipe is equipped with a counterweight.

[0011] Furthermore, the first suction pipe and the second suction pipe are connected to the filter via the first valve and the second valve, respectively.

[0012] The beneficial effects of this utility model are as follows: By setting a sealing cover on the collection box for sealing, when the water pump draws water from the collection box, a negative pressure will be formed, which will accelerate the flow of the third suction pipe into the collection box, improve the suction power of the third suction pipe and thus obtain a higher suction capacity. It can better suck the dirt and diseased and dead fish at the bottom of the breeding pond into the collection box, and avoid the rotting of diseased and dead fish from affecting the water quality.

[0020] like Figure 1 , Figure 2 , Figure 3As shown, an embodiment of this utility model provides a sludge suction device for a land-based cylindrical aquaculture pond of giant spiny loach, including: an aquaculture pond 1, a first sludge suction pipe 2, a second sludge suction pipe 3, a collection box 4, a third sludge suction pipe 5, and a filter 6. The bottom of the aquaculture pond 1 is inverted conical. One end of the first sludge suction pipe 2 is connected to the filter 6, and the other end of the first sludge suction pipe 2 extends to the lowest point of the bottom of the aquaculture pond 1. One end of the second sludge suction pipe 3 is connected to the filter 6, and the other end of the second sludge suction pipe 3 is connected to the inner cavity of the collection box 4. The bottom of the collection box 4 is 20cm to 30cm lower than the water level of the aquaculture pond 1. One end of the third sludge suction pipe 5 is connected to the bottom of the collection box 4, and the other end of the third sludge suction pipe 5 extends to the bottom of the aquaculture pond 1. The extended end of the third sludge suction pipe 5 is spaced 30cm to 60cm from the first sludge suction pipe 2. A sealing cover 7 is provided on the upper part of the collection box 4, which covers the upper opening of the collection box 4 and is connected to the collection box 4 by a locking buckle 8.

[0021] The first suction pipe 2 and the second suction pipe 3 of this device are used alternately and are adjusted by the first valve 17 and the second valve 18. Normally, the suction operation is mainly carried out by the first suction pipe 2. Under the action of water flow, the diseased fish, dead fish, fish feces and other waste at the bottom of the pond will accumulate at the lowest point of the inverted cone bottom of the breeding pond 1. The end of the first suction pipe 2 is equipped with a filter screen 15, which can prevent diseased fish and dead fish from being sucked in and avoid clogging the filter 6. After the first suction pipe 2 has been suctioning for a period of time, by adjusting the first valve 17 and the second valve 18, water in the collection tank 4 is drawn through the first suction pipe 2. After the water level in the collection tank 4 drops, a liquid level difference is generated. At the same time, since the upper part of the collection tank 4 is sealed by the sealing cover 7, a negative pressure zone is formed after the water is drawn away. Under the dual effect of the liquid level difference and the negative pressure zone, the water in the aquaculture pond will flow into the collection tank 4 from the third suction pipe 5. Compared with the traditional water flow generated by the liquid level difference alone, which generally only forms a water flow of about 0.1m / s in the third suction pipe 5, this device can generate higher suction through the negative pressure zone, which can more effectively suck diseased and dead fish from the third suction pipe 5 into the collection tank 4. When suctioning waste through the second suction pipe 3, the power of the water pump 14 needs to be adjusted so that the water flow velocity in the third suction pipe 5 is below 0.4 m / s. This prevents the flow velocity from being too high and causing normal fish to be unable to escape. When normal spiny loaches are sucked into the third suction pipe 5, their tendency to swim upstream is stimulated, causing them to rush out of the third suction pipe 5 and avoid being sucked into the collection box 4. Diseased fish, dead fish, and a small number of normal fish that have been accidentally sucked into the collection box 4 are blocked by the filter screen 15 and remain in the collection box 4. The internal situation can be observed through the transparent sealing cover 7, and it can be opened and cleaned regularly. Normal fish are returned to the breeding pond 1, while diseased and dead fish are disposed of. This achieves the purpose of absorbing waste and diseased and dead fish, preventing diseased and dead fish from accumulating at the bottom of the breeding pond 1 and decaying, thus affecting the growth of other fish.

[0022] The sealing cover 7 is designed to be detachable, so that farmers can clean the collection box 4 regularly. The filter 6 filters the water that is drawn in and returns fish food, feces and other waste to the breeding pond 1, thereby ensuring the water quality in the breeding pond 1 and improving the survival rate of the fish.

[0023] In a specific embodiment, such as Figure 2 , Figure 3 As shown, the lower part of the sealing cover 7 is provided with a limiting groove 9, and a rubber gasket 10 is provided in the limiting groove 9. The sealing cover 7 is connected to the upper edge of the collection box 4 through the limiting groove 9. The limiting groove 9 positions the upper edge of the collection box 4, so that the sealing cover 7 fits tightly with the collection box 4, and seals the gaps by the sealing cover 7 to improve airtightness, so as to form a negative pressure zone above the collection box 4 and improve the suction power of the third suction pipe 5.

[0024] Preferably, the sealing cover 7 is made of transparent plastic, such as PMMA (acrylic) or PC (polycarbonate), so that the fish farmer can observe the situation in the collection box 4 through the sealing cover 7, so as to deal with the diseased and dead fish in the collection box 4 in a timely manner. The collection box 4 is located near the outer edge of the breeding pond 1, so that the fish farmer can clean the collection box 4.

[0025] Preferably, such as Figure 3 As shown, the lower end of the latch 8 is hinged to the collection box 4. The upper part of the latch 8 is provided with a sleeve 11, and the upper edge of the sealing cover 7 is provided with a limiting strip 12. The latch 8 is pressed tightly against the upper part of the sealing cover 7 through the sleeve 11. The limiting strip 12 blocks both sides of the sleeve 11. The latch 8 can rotate. The upper part of the latch 8 is limited by the limiting strip 12, so that it is kept pressed tightly against the sealing cover 7, ensuring a tight connection between the sealing cover 7 and the collection box 4.

[0026] Specifically, a return water main pipe 13 is provided around the aquaculture pond 1. The filter 6 is connected to the return water main pipe 13 through a water pump 14. The return water main pipe 13 is connected to the inside of the aquaculture pond 1 through multiple return water branch pipes. After being filtered by the filter 6, the water is sent to the periphery of the aquaculture pond 1 through the pipe 13, and the water in the return water main pipe 13 is returned to the aquaculture pond 1 through the return water branch pipes to realize the circulation of water.

[0027] Specifically, the ends of the first suction pipe 2 and the second suction pipe 3 are equipped with filter screens 15 to prevent diseased and dead fish from flowing into the filter 6 through the first suction pipe 2 and the second suction pipe 3. The extension end of the third suction pipe 5 is equipped with a counterweight block 16 to prevent the end of the third suction pipe 5 from swinging, so as to ensure that the third suction pipe 5 can suck up the dirt from the lowest point of the breeding pond 1.

[0028] Preferably, the first suction pipe 2 and the second suction pipe 3 are connected to the filter 6 through the first valve 17 and the second valve 18, respectively. The first suction pipe 2 and the second suction pipe 3 can be adjusted to alternately suck up dirt through the first valve 17 and the second valve 18. After the dead and diseased fish are gathered by the first suction pipe 2, the dirt is then sucked up by the second suction pipe 3 and the third suction pipe 5, which effectively cleans up the dead and diseased fish.

[0029] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
