Description

Technical Field

[0001] This utility model relates to the technical field of aquaculture pond water level control devices, and in particular to an aquaculture pond overflow discharge and water level control device. Background Technology

[0002] For the discharge of uneaten feed and manure in aquaculture systems, a sewage discharge shaft is generally built next to the aquaculture pond. The depth of the sewage discharge shaft is similar to that of the aquaculture pond, and the bottom of the sewage discharge shaft is connected to the bottom of the aquaculture pond by a pipe. A pipe switch valve is installed at the bottom of the sewage discharge shaft. The discharge of uneaten feed and manure is controlled by opening and closing the switch valve. There are generally two types of switch valves: manual valves or electric valves.

[0003] The commonly used manual valves are operated as follows: Through aeration, circulation, and other facilities, all waste generated by aquaculture is collected at the bottom of the pond. The manual drain valve located at the bottom of the drainage shaft is then opened or the hose is pulled out to discharge uneaten feed and feces from the pond. After discharge, the valve or hose is closed by the worker. However, there are several drawbacks. First, drainage shafts are generally deep, requiring time and effort for workers to climb in and out. Second, the odor in the drainage shafts is strong, especially in summer, creating a poor working environment for workers. Third, the drainage shafts are often damp, making the valves prone to rust and damage. Due to the limited space inside the shaft, even valve replacement is quite difficult. Furthermore, the water flow height cannot be adjusted during drainage, meaning that after opening the valve, the drainage time can only be manually controlled, making it difficult to maintain water circulation while simultaneously emptying the pond of waste. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a device for overflow discharge and water level control of aquaculture ponds that is convenient for daily maintenance and can control the water level in real time.

[0005] The technical solution adopted by this utility model is as follows: This utility model includes a breeding pond, an escape-proof net installed at the bottom of the breeding pond, a circulation and drainage pipe connected to the bottom of the escape-proof net, a graded drainage component connected to the circulation and drainage pipe, and a sewage tank connected to the output end of the graded drainage component. The graded drainage component includes a connecting pipe, a first drainage pipe, a second drainage pipe, a third drainage pipe, and an output pipe. One end of the first drainage pipe, the second drainage pipe, and the third drainage pipe are connected to the connecting pipe from bottom to top. The other end of the first drainage pipe, the second drainage pipe, and the third drainage pipe are connected to the output pipe from top to bottom. The output pipe is connected to the sewage tank. The second drainage pipe is equipped with a second control valve, and the third drainage pipe is equipped with a third control valve.

[0006] Furthermore, the top of the escape-proof net is provided with a fixing plate, which has several slots, and each slot is provided with an aeration pipe.

[0007] Furthermore, the aeration pipe has a ring-shaped structure.

[0008] Furthermore, a sludge collection well is formed at the bottom of the escape-proof net, one side of the buffer chamber is connected to the connecting pipe, and the other side of the buffer chamber is provided with a circulation and sewage pipe for connecting to the aquaculture water treatment equipment.

[0009] Furthermore, a siphon-breaking pipe is formed in the middle of the first drain pipe.

[0010] Furthermore, the first drainage pipe is positioned at the same height as the highest water level of the aquaculture pond, the second drainage pipe is located at two-thirds of the water level of the aquaculture pond, and the third drainage pipe is located at one-third of the water level of the aquaculture pond.

[0011] Furthermore, the first drainage pipe is positioned at the same height as the highest water level of the aquaculture pond, the second drainage pipe is located at the three-quarters water level of the aquaculture pond, and the third drainage pipe is located at the one-quarter water level of the aquaculture pond.

[0012] Furthermore, a main sewage pipe is installed at the bottom of the sewage tank, and the main sewage pipe is connected to an external wastewater treatment device.

[0013] The beneficial effects of this utility model are as follows: Because the graded drainage component of this utility model uses a structure with multiple drainage pipes and control valves, the height of the first drainage pipe is flush with the highest water level of the aquaculture pond. When the second and third control valves are closed, uneaten feed and feces flow into the sewage pond along the first discharge pipe. Through the principle of communicating vessels, the water level in the aquaculture pond remains stable, while real-time sewage discharge is achieved, shortening the retention time of uneaten feed and feces in the aquaculture pond and ensuring normal fish growth. When the second or third control valve is opened, under atmospheric pressure, water flows out along the second or third drainage pipe, no longer passing through the first drainage pipe, causing the water level in the aquaculture pond to drop. Water level adjustment in the aquaculture pond can be completed simply by controlling the opening and closing of the second and third control valves. The structure is simple and easy to use, reducing the workload of staff. Attached Figure Description

[0021] Example 1

[0022] like Figures 1 to 5As shown, in this embodiment, the present invention includes a breeding pond 1, an escape-proof net 2 disposed at the bottom of the breeding pond 1, a circulation and drainage pipe 3 connected to the bottom of the escape-proof net 2, a graded drainage assembly 4 connected to the circulation and drainage pipe 3, and a sewage tank 5 connected to the output end of the graded drainage assembly 4. The graded drainage assembly 4 includes a connecting pipe 41, a first drainage pipe 42, a second drainage pipe 43, a third drainage pipe 44, and an output pipe 45. One end of the first drainage pipe 42, the second drainage pipe 43, and the third drainage pipe 44 are connected to the connecting pipe 41 from bottom to top, and the other end of the first drainage pipe 42, the second drainage pipe 43, and the third drainage pipe 44 are connected to the output pipe 45 from top to bottom. The output pipe 45 is connected to the sewage tank 5. The second drainage pipe 43 is provided with a second control valve 46, and the third drainage pipe 44 is provided with a third control valve 47. The valve and the second control valve 46 are manual or electric regulating valves used to control the opening and closing of the second drain pipe 43 and the third drain pipe 44. The graded drainage assembly 4 adopts a structure with multiple drain pipes and control valves. The height of the first drain pipe 42 is level with the highest water level line of the breeding pond 1. When the second control valve 46 and the third control valve 47 are closed, the uneaten feed and feces flow into the sewage pond 5 along the first discharge pipe. Through the principle of communicating vessels, the water level in the breeding pond 1 is kept stable, and real-time sewage discharge can be achieved. This shortens the retention time of uneaten feed and feces in the breeding pond 1, reduces pollution to the breeding water, and ensures the normal growth of fish. When the second control valve 46 or the third control valve 47 is opened, under the action of atmospheric pressure, the water flows out along the second drain pipe 43 or the third drain pipe 44, no longer passing through the first drain pipe 42, causing the water level in the breeding pond 1 to drop. The water level of the breeding pond 1 can be adjusted by simply controlling the opening and closing of the second control valve 46 and the third control valve 47. The structure is simple and easy to use.

[0023] In this embodiment, a fixing plate 21 is provided on the top of the escape-proof net 2. The fixing plate 21 forms a plurality of slots 22. Each slot 22 is provided with an aeration pipe 23. The aeration pipe 23 is located above the escape-proof net 2, forming aeration and oxygenation to push the water flow upward. The water that reaches the surface of the pool flows around and flows back along the side wall of the aquaculture pool 1 to the direction of the escape-proof net 2, pushing the uneaten feed and feces at the bottom of the aquaculture pool 1 through the escape-proof net 2 into the sewage collection well 24.

[0024] In this embodiment, the aeration pipe 23 has a ring structure.

[0025] In this embodiment, a sludge collection well 24 is formed at the bottom of the escape-proof net 2. One side of the sludge collection well 24 is connected to the connecting pipe 41, and the other side of the sludge collection well 24 is provided with a circulation and sewage pipe 7 for connecting aquaculture water treatment equipment.

[0026] In this embodiment, a siphon breaking pipe 48 is installed in the middle of the first drain pipe 42 to prevent siphoning during drainage.

[0027] In this embodiment, the first drain pipe 42 is positioned at the same height as the highest water level of the aquaculture pond 1, the second drain pipe 43 is located at two-thirds of the water level of the aquaculture pond 1, and the third drain pipe 44 is located at one-third of the water level of the aquaculture pond 1.

[0028] In this embodiment, a main sewage pipe 6 is provided at the bottom of the sewage tank 5, and the main sewage pipe 6 is connected to an external wastewater treatment device.

[0029] Example 2

[0030] like Figure 6 As shown, in this embodiment, the first drain pipe 42 is positioned at the same height as the highest water level of the aquaculture pond 1, the second drain pipe 43 is located at the three-quarters water level of the aquaculture pond 1, and the third drain pipe 44 is located at the one-quarter water level of the aquaculture pond 1. The remaining technical features are the same as in Embodiment 1.

[0031] The working principle of this utility model:

[0032] The height of the first drain pipe 42 is level with the highest water level of the breeding pond 1. When the second control valve 46 and the third control valve 47 are closed, the uneaten feed and feces flow into the sewage tank 5 along the first discharge pipe. Through the principle of communicating vessels, the water level in the breeding pond 1 is kept stable. The uneaten feed and feces accumulated at the bottom of the breeding pond 1 pass through the escape-proof net 2 and enter the sewage collection well 24, and are discharged into the sewage tank 5 through the output pipe 45. After the second control valve 46 or the third control valve 47 is opened, under the action of atmospheric pressure, the water flows out along the second drain pipe 43 or the third drain pipe 44, no longer passing through the first drain pipe 42, causing the water level in the breeding pond 1 to drop. The water level of the breeding pond 1 can be adjusted by simply controlling the opening and closing of the second control valve 46 and the third control valve 47.

[0033] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
