Automatic dredging and sewage device for aquaculture

Abstract

This utility model provides an automatic sludge removal and sewage discharge device for aquaculture, relating to the field of aquaculture technology. It includes an aquaculture pond and a mud pump, with the mud pump located above the pond. The top of the pond has an I-shaped sliding power mechanism for moving the mud pump. When sludge removal and sewage discharge are required at the bottom of the pond, the mud pump and extraction pipe move in all directions through the cooperation of a first and second moving block, thereby cleaning sludge from various locations within the pond. Simultaneously, during the extraction of sludge by the extraction pipe, a high-pressure water jet is sprayed from a spiral water spray pipe and rotated to thoroughly wash the sludge near the extraction pipe, making the sludge near the extraction pipe looser. This accelerates the sludge extraction speed of the sewage discharge device, thus improving the overall efficiency of sludge removal and sewage discharge.

Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to an automatic dredging and sewage discharge device for aquaculture. Background Technology

[0002] Automatic sludge removal and sewage discharge devices are specially designed to clean sludge and pollutants from the bottom of aquaculture ponds. Their core purpose is to improve water quality, minimize human intervention, and optimize the overall aquaculture environment. When applied to aquaculture ponds, these devices not only significantly improve the aquaculture environment but also effectively reduce labor costs and mitigate negative impacts on the natural ecosystem.

[0003] When carrying out dredging and sewage discharge operations at the bottom of aquaculture ponds, sewage discharge devices are usually used to extract the silt from the bottom of the pond. However, because the bottom of the aquaculture pond has not been cleaned for a long time, the silt tends to accumulate and become thick and hard. This situation will cause the sewage discharge device to slow down when extracting this hardened silt, thus affecting the efficiency of the entire dredging and sewage discharge process.

[0004] Therefore, it is necessary to provide an automatic dredging and sewage discharge device for aquaculture to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic sludge removal and sewage discharge device for aquaculture.

A rotating ring is fixedly installed on the side of the spiral water spray pipes near the extraction pipe. The rotating ring is located on the lower side of the extraction pipe, and multiple triangular blades are fixedly installed in a circular arrangement on the inner wall of the rotating ring.

[0010] Preferably, the distance from the bottom end of the spiral water spray pipe to the inner wall of the bottom of the aquaculture pond is less than the distance from the bottom end of the extraction pipe to the inner wall of the bottom of the aquaculture pond.

[0011] Preferably, the diameter of the spiral water spray pipe is much smaller than the diameter of the extraction pipe.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figures 1 to 5 An automatic sludge removal and sewage discharge device for aquaculture includes an aquaculture pond 1 and a mud pump 3, with the mud pump 3 located above the aquaculture pond 1. The top of the aquaculture pond 1 is slidably equipped with a power mechanism for moving the mud pump 3 in an I-shape.

[0021] A suction pipe 31 is fixedly installed at the bottom of the mud pump 3. The outer side of the suction pipe 31 is spirally equipped with a rotating mechanism for flushing sludge.

[0022] In practical implementation, the automatic sludge removal and sewage discharge device for aquaculture provided by this utility model has the following beneficial effects: When it is necessary to remove sludge from the bottom of the aquaculture pond 1, the mud pump 3 and the extraction pipe 31 are driven to move in all directions through the cooperation of the first moving block 23 and the second moving block 27, thereby cleaning the sludge in various locations inside the aquaculture pond 1. At the same time, during the process of the extraction pipe 31 extracting sludge, high-pressure water jets are sprayed out through the spiral water spray pipe 43 and rotated to wash the sludge near the extraction pipe 31 in all directions, thereby making the sludge near the extraction pipe 31 more loose. This situation will accelerate the extraction speed of the sewage discharge device.

[0023] The differences in the inlet and outlet dimensions of the dredging pump shown in the pictures and text are for reference only. The actual inlet and outlet dimensions of the dredging pump should be referred to the actual product.

[0024] refer to Figure 1 , Figure 3 and Figure 4 As shown, the power mechanism includes a first slot plate 2, which is fixedly installed on the top of the aquaculture pond 1. A drive motor 21 is fixedly installed on the left side of the first slot plate 2. The right end of the drive motor 21 penetrates the inner wall of the left side of the first slot plate 2. A first rotating screw 22 is fixedly installed at the output end of the drive motor 21 that extends into the first slot plate 2. A first moving block 23 is threadedly connected to the first rotating screw 22. The first moving block 23 is slidably engaged with the first slot plate 2. A second slot plate 24 is fixedly installed on the top of the first moving block 23. A power motor 25 is fixedly installed on the front side of the second slot plate 24. The rear end of the power motor 25 penetrates the inner wall of the front side of the second slot plate 24. A second rotating screw 26 is fixedly installed at the output end of the power motor 25 that extends into the second slot plate 24. A second moving block 27 is threadedly connected to the second rotating screw 26. A mud pump 3 is detachably installed on the top of the second moving block 27 via a bracket.

[0025] It should be noted that the mud pump 3 and the extraction pipe 31 are moved in all directions within the aquaculture pond 1 through the coordination of the internal structure of the power mechanism.

[0026] refer to Figure 2 and Figure 5 As shown, the rotating mechanism includes a circular water storage tank 4, which is fixedly installed on the outside of the extraction pipe 31 near the bottom. A circular groove 41 is provided at the bottom of the circular water storage tank 4, and a circular sealing plate 42 is movably engaged in the circular groove 41. Multiple spiral water spray pipes 43 are fixedly installed in a circular arrangement at the bottom of the circular sealing plate 42. A rotating ring 44 is fixedly installed on the side of the spiral water spray pipes 43 near the extraction pipe 31. The rotating ring 44 is located on the lower side of the extraction pipe 31, and multiple triangular blades 45 are fixedly installed in a circular arrangement on the inner wall of the rotating ring 44.

[0027] It should be noted that the sludge near the extraction pipe 31 is rotated and flushed by the cooperation of the internal structure of the rotating mechanism, which facilitates the extraction of the sludge from the extraction pipe 31.

[0028] refer to Figure 5 As shown, the distance from the bottom end of the spiral water spray pipe 43 to the inner wall of the bottom of the breeding pond 1 is less than the distance from the bottom end of the extraction pipe 31 to the inner wall of the bottom of the breeding pond 1.

[0029] It should be noted that the spiral water spray pipe 43 can be inserted into the silt for flushing and rotation.

[0030] refer to Figure 5 As shown, the diameter of the spiral water spray pipe 43 is much smaller than the diameter of the extraction pipe 31.

[0031] It should be noted that the water flow from the spiral water spray pipe 43 has little impact on the overall extraction efficiency of the extraction pipe 31.

[0032] The working principle of the automatic sludge removal and sewage discharge device for aquaculture provided by this utility model is as follows: In use, the water in the aquaculture pond 1 is first initially drained. Then, the mud pump 3 is fixed to the second movable clamping block 27 via a screw. The output end of the mud pump 3 is connected to an external pipe, and the top of the annular water storage tank 4 is connected to an external high-pressure water pipe. The CPU controls the rotation direction and speed of the drive motor 21 and the power motor 25, as well as when they are turned on, and simultaneously controls the opening and closing of the mud pump 3. When the drive motor 21 is started, it drives the first rotating screw 22 to rotate. The first rotating screw 22 rotates under the constraint of the first clamping plate 2. The first moving block 23 moves left and right, which in turn moves the second slot plate 24 left and right. The second slot plate 24, through the second moving block 27 and other structures, moves the mud pump 3 left and right. When the power motor 25 is started, it drives the second rotating screw 26 to rotate. Under the constraint of the second slot plate 24, the second rotating screw 26 drives the second moving block 27 to move back and forth. The second moving block 27, through the bracket, moves the mud pump 3 back and forth. Through the cooperation of the first moving block 23 and the second moving block 27 and other structures, the mud pump 3 moves back, forth, left, and right, causing the mud pump 3 to drive the extraction pipe. 31 can move omnidirectionally within the aquaculture pond 1, allowing the mud pump 3 to clean and discharge sludge from various locations at the bottom of the aquaculture pond 1 via the extraction pipe 31. When the extraction pipe 31 moves, the mud pump 3 is activated, extracting and discharging sludge from the bottom of the aquaculture pond 1 through the extraction pipe 31. Simultaneously, water is injected into the annular water storage tank 4 through the external high-pressure water pipe. The water flow is sprayed out through the spiral water spray pipe 43 to form a high-pressure water jet to wash the sludge, causing the hardened sludge to gradually loosen after being washed. At the same time, due to the spiral design of the spiral water spray pipe 43, the spiral water spray pipe 43 is subjected to a reverse thrust when spraying water and impacting the sludge, causing it to rotate at high speed from side to side. As the spiral water spray pipes 43 rotate, they thoroughly wash the silt near the extraction pipe 31, making the silt looser and easier for the extraction pipe 31 to extract. At the same time, the rotation of multiple spiral water spray pipes 43 drives the rotating ring 44 to rotate, which in turn drives the triangular blade 45 to rotate at high speed. During the rotation, the triangular blade 45 breaks up and cleans the impurities that are about to be sucked into the extraction pipe 31, thus preventing large pieces of impurities from being sucked into the mud pump 3 and causing blockage. This situation accelerates the silt extraction speed of the sewage discharge device, thereby improving the overall efficiency of dredging and sewage discharge.
