Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a device for removing floating debris from the surface of an aquaculture pond. Background Technology

[0002] The current aquaculture industry generally requires the construction of ponds for aquaculture. However, during the aquaculture process, some impurities or foam will float on the water surface, which need to be regularly removed by aquaculture workers. Since the aquaculture ponds are generally quite large, removing the floating debris and foam from the water surface is time-consuming and laborious, increasing the workload of aquaculture workers and causing inconvenience to aquaculture. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a device for removing floating debris from the surface of aquaculture ponds.

[0004] This utility model is implemented by the following method: a device for removing floating debris from aquaculture ponds, including an aquaculture pond, a water-pushing device in the aquaculture pond, a sewage discharge opening on the side of the aquaculture pond, the height of the sewage discharge opening being lower than the water level in the aquaculture pond, a foam guide in the aquaculture pond, the foam guide extending from the center of the aquaculture pond to the sewage discharge opening, the upper end of the foam guide being higher than the water level in the aquaculture pond, and the lower end of the foam guide being lower than the water level in the aquaculture pond. Preferably, the foam guide is located on one side of the drain opening and on the side of the aquaculture pond where the water flows away from the drain opening.

[0005] Preferably, the foam guide is a floating tube.

[0006] Preferably, the floating tube is provided with multiple nozzles, and the spray direction of the nozzles is towards the direction in which the water flow of the pushing device flows towards the floating tube.

[0007] Preferably, the nozzle outlet is located at the water surface of the aquaculture pond, and the floating tube is provided with a water supply pipe, which is connected to the nozzle.

[0008] Preferably, the aquaculture pond is provided with a positioning column, and a first longitudinal positioning groove is formed on the side wall of the aquaculture pond adjacent to the sewage discharge gap. The positioning column stands in the aquaculture pond and has a second longitudinal positioning groove. One end of the floating tube is located in the first positioning groove, and the other end of the floating tube is located in the second positioning groove. The floating tube is cuboid in shape, and the shapes of its two ends match the first positioning groove and the second positioning groove.

[0009] Preferably, there is one or more drainage gaps, and correspondingly, there is one or more floating pipes.

[0010] Preferably, the drainage opening is formed from the top of the aquaculture pond downwards, and the lower end of the drainage opening is 2mm-40mm below the water surface in the aquaculture pond.

[0011] Preferably, the drain opening is connected to a foam discharge pipe.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a device for removing floating debris from the surface of an aquaculture pond. Compared with the prior art, this utility model has at least the following technical effects: 1. The water-pushing device pushes the water flow, and the impurities or foam floating on the water surface move under the action of the water flow. The sewage discharge gap is lower than the water surface, forming a water level difference. By utilizing the natural flow of the water and the water level difference, the floating debris is carried to the sewage discharge gap. When the water flows and rotates in the aquaculture pond, it also generates centrifugal force, causing the floating debris to move towards the outer circle of the aquaculture pond, which is more conducive to pushing floating impurities such as foam to the sewage discharge gap. The foam guide extends from the center of the aquaculture pond to the sewage discharge gap, which can form a continuous guiding channel at the water surface to prevent floating debris such as foam from crossing the sewage discharge gap, so as to guide the floating debris such as foam into the sewage discharge gap as much as possible, which greatly improves the cleaning efficiency of floating debris and avoids the laborious and inefficient manual retrieval. 2. Positioning the foam guide on the side where the water flow departs from the drain opening optimizes the system's flow. As the water passes the foam guide, it creates a force that propels floating debris towards the drain opening, allowing it to flow smoothly along the guide. 3. Multiple nozzles are installed on the floating tube, with the nozzles spraying towards the direction of the water flow from the water-pushing device. This design prevents foam from adhering to the floating tube, further enhancing its cleaning ability. 4. Positioning columns are installed in the aquaculture pond. A first positioning groove is formed on the pond's side wall, and a second positioning groove is formed on the column. Both ends of the floating tube are located in these two grooves, with the tube's shape matching the grooves. This positioning structure effectively fixes the floating tube's position. Under long-term water flow, the floating tube will not shift, ensuring the stability of the foam guide and thus ensuring the entire system operates stably, continuously and effectively guiding floating debris to the drain opening. It also prevents the floating tube from rotating, thus preventing the nozzles from deviating from the water surface. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Please see Figures 1 to 2 A device for removing floating debris from aquaculture pond 1 includes an aquaculture pond 1, a water-pushing device 2 in the aquaculture pond 1, a sewage discharge opening 3 on the side of the aquaculture pond 1, the height of the sewage discharge opening 3 being lower than the water level in the aquaculture pond 1, a foam guide 4 in the aquaculture pond 1, the foam guide 4 extending from the center of the aquaculture pond 1 to the sewage discharge opening 3, the upper end of the foam guide 4 being higher than the water level in the aquaculture pond 1, and the lower end of the foam guide 4 being lower than the water level in the aquaculture pond 1. The water-pushing device 2 propels the water flow, causing floating impurities or foam to move under its influence. Since the drain opening 3 is lower than the water surface, a water level difference is created. Utilizing the natural flow of water and this water level difference, floating objects are propelled towards the drain opening 3. The foam guide 4 extends from the center of the aquaculture pond 1 to the drain opening 3, forming a continuous guiding channel at the water surface to prevent floating objects like foam from crossing the drain opening 3. This significantly improves the efficiency of cleaning floating objects, avoiding the laborious and inefficient manual retrieval. As the water circulates in the aquaculture pond 1, centrifugal force is generated, causing floating objects to move towards the outer edge of the pond, further facilitating the pushing of floating impurities like foam towards the drain opening 3. Preferably, the specific structure of the water-pushing device 2 can be found in patent document CN221059290U.

[0018] Please see Figures 1 to 2 Preferably, the foam guide 4 is located on one side of the drainage gap 3, and on the side of the aquaculture pond 1 where the water flow is away from the drainage gap 3. This optimized positioning of the foam guide 4 allows for full utilization of the water flow generated by the water-pushing device 2. When the water flows past the foam guide 4, it creates a force that propels the floating objects towards the drainage gap 3, enabling them to flow smoothly along the guide towards the drainage gap 3.

[0019] Please see Figures 1 to 2 Preferably, the foam guide 4 is a floating tube. The floating tube is usually made of lightweight and water-resistant materials such as polyethylene, which allows it to float stably on the water surface and is not easy to sink or be damaged.

[0020] Please see Figures 1 to 2Preferably, the floating tube is equipped with multiple nozzles 5, and the spray direction of the nozzles 5 is in the direction that the water flow from the water-pushing device 2 flows towards the floating tube. This design, with multiple nozzles 5 on the floating tube and spraying water in the direction that the water flow from the water-pushing device 2 flows towards the floating tube, prevents foam from adhering to the floating tube, further enhancing the cleaning ability of floating debris. Alternatively, a floating tube without nozzles 5 can be used. A floating tube with nozzles 5 is connected to a water pipe, which extends from one side of the first positioning groove 7 into the aquaculture pond 1 and connects to the water supply pipe in the floating tube. The floating tube can be made of materials such as EPP or EPS to provide sufficient buoyancy.

[0021] Please see Figures 1 to 2 Preferably, the outlet of the nozzle 5 is located at the water surface of the aquaculture pond 1, and a water supply pipe is provided in the floating tube, which is connected to the nozzle 5. Having the outlet at the water surface allows the sprayed water to directly act on floating objects, improving the efficiency of the spray on the floating objects, avoiding energy waste caused by improper spraying position, and ensuring efficient cleaning.

[0022] Please see Figures 1 to 2 Preferably, the aquaculture pond 1 is equipped with a positioning column 6, and a longitudinal first positioning groove 7 is formed on the side wall of the aquaculture pond 1 adjacent to the sewage discharge opening 3. The positioning column 6 stands in the aquaculture pond 1, and the positioning column 6 has a longitudinal second positioning groove 8. One end of the floating tube is located in the first positioning groove 7, and the other end of the floating tube is located in the second positioning groove 8. The floating tube is cuboid, and the shapes of its two ends match the first positioning groove 7 and the second positioning groove 8. The positioning column 6 is set in the aquaculture pond 1, the first positioning groove 7 is formed on the side wall of the aquaculture pond 1, and the positioning column 6 has a second positioning groove 8. The two ends of the floating tube are respectively located in these two positioning grooves, and the shape of the floating tube matches the positioning grooves. This positioning structure can effectively fix the position of the floating tube. Under the long-term action of water flow, the floating tube will not be displaced, ensuring the stability of the foam guide 4, thereby ensuring that the entire device can operate stably, continuously and effectively guide floating objects to the sewage discharge opening 3, and preventing the floating tube from rotating, thereby preventing the nozzle 5 from deviating from the water surface. The scale of the floating tube, the first positioning groove 7, and the second positioning groove 8 in the accompanying drawings of this embodiment is for the convenience of showing the corresponding structure. The actual size scale differs from that in the accompanying drawings.

[0023] Please see Figures 1 to 2 Preferably, there is one or more drainage gaps 3, and correspondingly, there is one or more floating pipes. The number of both can be flexibly adjusted according to actual factors such as the size and shape of the aquaculture pond 1 and the distribution of floating objects.

[0024] Please see Figures 1 to 2Preferably, the drainage opening 3 is formed from the top of the aquaculture pond 1 downwards, and the lower end of the drainage opening 3 is 2mm-40mm below the water surface in the aquaculture pond 1. When the height difference between the lower end of the drainage opening 3 and the water surface is within this range, it ensures that floating objects can smoothly flow into the drainage opening 3 using the water level difference, while avoiding excessive water outflow due to the opening being too low, which would waste water resources and destabilize the aquaculture environment. The floating range of the floating tube should match this size.

[0025] Please see Figures 1 to 2 Preferably, the drainage outlet 3 is connected to a foam discharge pipe 9. This allows floating debris to be collected and treated in a concentrated manner, preventing it from accumulating around the aquaculture pond 1, effectively preventing secondary pollution, and maintaining the cleanliness of the aquaculture environment.

[0026] The working principle of this utility model is as follows: The water-pushing device 2 propels the water flow in the aquaculture pond 1, causing it to rotate. Once the flow is established, impurities and foam floating on the surface of the pond are pulled along by the current and move towards the side wall of the pond. Because the height of the drain opening 3 is lower than the water level in the pond, a water level difference is created, allowing surface water to flow out through the opening. This allows most of the floating debris and some water to flow out through the drain opening 3 and into the foam discharge pipe 9.

[0027] Some of the floating debris also collided with the foam guide 4 as the water was pushed. Due to the blocking and guiding effect of the foam guide 4, the floating debris could not continue to circulate in the aquaculture pond 1 following the direction of the water push. The floating debris could only move towards the drain opening 3 along the extension direction of the floating pipe. At the same time, the nozzles 5 on the floating pipe sprayed water to prevent foam from adhering to the surface of the floating pipe, so that as much foam as possible was carried into the drain opening 3 for discharge.

[0028] The floating debris continues to move forward with the water flow in the foam discharge pipe 9 and is eventually guided to the designated collection location, thus achieving the purpose of discharging the floating debris from the aquaculture pond 1 and keeping the surface of the aquaculture pond 1 clean.
