Description

Technical Field

[0001] This utility model relates to the technical field of aquaculture auxiliary equipment, specifically to an integrated overflow and sewage discharge pipe for aquaculture ponds. Background Technology

[0002] High-density aquaculture is a trend in modern fisheries. Water quality is one of the most fundamental environmental factors in high-density aquaculture and a major factor affecting fish growth. The accumulation of uneaten feed and fish feces in the pond water can affect fish growth and health. Furthermore, changes in water quality can also affect fish appetite and activity. Therefore, maintaining clean and stable water quality is crucial for fish farming. Waste removal is an important aspect of maintaining water cleanliness, primarily involving the removal of feces, shed skin, and other debris from the pond.

[0003] Currently, aquaculture ponds typically use a dedicated sewage discharge device at the bottom to remove impurities from the bottom, and an overflow pipe at the edge of the pond to remove light pollutants such as ink from the surface water. This requires two sewage discharge systems, which is quite complex and results in high operating costs for large aquaculture ponds. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an integrated overflow and sewage discharge pipe for aquaculture ponds, which realizes both sewage discharge and overflow functions using a single sewage pipe, simplifying the sewage system structure of aquaculture ponds.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An integrated overflow and sewage discharge pipe for aquaculture ponds includes a sewage discharge pipe and an inner pipe. The sewage discharge pipe is installed at the center of the aquaculture pond and passes through the bottom plate of the aquaculture pond from bottom to top. The sewage discharge pipe has multiple sewage discharge ports at the upper end of the bottom plate. The inner pipe is inserted into the sewage discharge pipe from top to bottom. A limit block is provided at the top of the sewage discharge pipe. An overflow hole is provided on the inner pipe. The inner pipe at the lower end of the overflow hole has sufficient length. The bottom end of the inner pipe extends to the lower end of the sewage discharge port, and a sealing ring is provided on the outer wall of the lower end of the inner pipe.

[0007] Furthermore, two sealing rings are provided.

[0008] Furthermore, the inner tube is a hollow structure.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This utility model has a simple structure and reasonable design. By designing an inner pipe that can move up and down inside the sewage pipe, it realizes the alternating discharge of sewage from the bottom of the aquaculture water and the overflow of surface water, which greatly simplifies the structure of the sewage pipe, improves the efficiency of sewage discharge, and reduces the cost of use.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1-3 As shown, an integrated overflow and sewage discharge pipe for aquaculture ponds includes a sewage pipe 1 and an inner pipe 2. The sewage pipe 1 is installed at the center of the aquaculture pond. Preferably, the bottom of the aquaculture pond is designed as a conical structure, and the sewage pipe 1 is installed at the bottom of the conical structure to facilitate the collection of impurities in the aquaculture pond. The sewage pipe 1 passes through the bottom plate 3 of the aquaculture pond from bottom to top. The sewage pipe 1 has multiple sewage outlets 11 at the upper end of the bottom plate 3. Water and impurities at the bottom of the aquaculture pond enter the sewage pipe 1 through the sewage outlets 11 and are discharged.

[0016] The inner tube 2 is inserted into the drain pipe 1 from top to bottom. The inner tube 2 is a hollow structure. A limit block 12 is provided at the top of the drain pipe 1 to restrict the downward movement of the inner tube 2, so that the inner tube 2 can be suspended on the drain pipe 1. An overflow hole 21 is provided on the inner tube 2 to discharge the surface water of the aquaculture pond. When the inner tube is suspended on the drain pipe 1, the surface water of the aquaculture pond enters the inner tube 2 through the overflow hole 21 and then exits from the drain pipe 1. The inner tube 2 at the lower end of 21 has sufficient length. When the inner tube is suspended on the sewage pipe 1, the bottom end of the inner tube 2 extends to the lower end of the sewage outlet 11. A sealing ring 22 is provided on the outer wall of the lower end of the inner tube 2. The sealing ring 22 is located between the sewage pipe 1 and the inner tube 2. The sealing ring 22 is made of plastic or rubber material and is used to prevent water from flowing out of the gap between the sewage pipe 1 and the inner tube 2 and entering the sewage pipe 1. To improve the sealing effect, two sealing rings 22 are provided.

[0017] The working principle of this utility model is as follows:

[0018] During normal use, the inner tube 2 is suspended on the drain pipe 1. At this time, the overflow hole 21 of the inner tube 2 is located above the drain pipe 1, and the bottom end of the inner tube 2 extends to the lower end of the drain outlet 11. With the cooperation of the sealing ring 22, the drain outlet 11 of the drain pipe 1 is sealed. The lower end of the drain pipe 1 is closed, and the surface water of the aquaculture pond flows from the overflow hole 21 of the inner tube 2 into the drain pipe 1, achieving the surface water overflow function. When it is necessary to drain the bottom water of the aquaculture pond, the inner tube 2 is lifted upwards so that the sealing ring 22 is above the drain outlet 11. At this time, the bottom water can enter the drain pipe 1 from the drain outlet 11, and simultaneously, the overflow hole 21 of the inner tube 2 moves above the water level line of the aquaculture pond, preventing the surface water from flowing out, thus achieving the bottom water drainage function. This invention can also be programmed mechanically to periodically lift the inner tube 2, achieving alternating bottom water drainage and surface water overflow.

[0019] This utility model has a simple structure and reasonable design. By designing an inner pipe that can move up and down inside the sewage pipe, it realizes the alternating discharge of sewage from the bottom of the aquaculture water and the overflow of surface water, which greatly simplifies the structure of the sewage pipe, improves the efficiency of sewage discharge, and reduces the cost of use.

[0020] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
