Technical Field

[0001] This utility model belongs to the field of fish farming technology, specifically a fish pond wastewater cleaning and recycling device. Background Technology

[0002] With the rapid development of modern aquaculture, water quality management and cleaning of fishponds have become crucial for ensuring healthy fish growth and improving aquaculture efficiency. As modern aquaculture technology advances, fish density in fishponds is gradually increasing, leading to more fish waste and microorganisms, which deteriorates water quality, hinders fish growth, and in severe cases, causes mass fish deaths. Traditional manual cleaning methods are not only time-consuming and labor-intensive but also struggle to guarantee timeliness and comprehensiveness. Furthermore, manual cleaning requires removing fish from the pond and draining the water, which can negatively impact water quality and the fish's growth environment, resulting in significant water waste. Therefore, there is a need to develop a device that can automatically and promptly remove fish waste and impurities from fishponds without harming the fish, while also filtering and recycling the water. Utility Model Content

[0003] To address the above technical problems, this utility model provides a device that can automatically clean fish feces and impurities in fish ponds in a timely manner without affecting the fish, and can also filter and recycle water resources. This solves the problems of traditional fish pond cleaning devices being time-consuming and labor-intensive, having a significant impact on fish, and wasting water resources.

[0004] To solve the above technical problems, the technical solution of this utility model is as follows: a fish pond sewage cleaning and circulation device, including a fish pond, a filter box fixedly connected to the side wall of the fish pond, a rotating shaft rotatably connected to the bottom of the fish pond, the rotating shaft being driven by a motor, a scraper fixedly connected to the bottom of the rotating shaft and a protrusion fixedly connected to the top of the rotating shaft, a bearing rotatably connected to the rotating shaft above the scraper, a filter plate fixedly connected to the outer ring of the bearing, the other side of the filter plate being fixedly connected to the inner wall of the fish pond, a rotating sleeve rotatably connected to the top of the rotating shaft, the protrusion cooperating with the rotating sleeve, a bracket fixedly connected to the outer side of the rotating sleeve, a connecting frame fixedly connected to the other end of the bracket, a brush fixedly connected to the bottom surface of the connecting frame, the lower end of the brush contacting the upper end of the filter plate, several water outlets are opened at the bottom of the fish pond, a water collection pipe is fixedly connected to the other end of the water outlet, the output end of the water collection pipe is connected to the bottom of one side of the filter box, and a water outlet pipe is fixedly connected to the top of the other side of the filter box, the output end of the water outlet pipe being located above the fish pond.

[0005] Furthermore, a groove is provided in the middle of the rotating sleeve, and a retractable protrusion is hinged in the middle of the groove, the protrusion cooperating with the raised part.

[0006] Furthermore, the filter box is equipped with three layers of filter screens.

[0007] Furthermore, water pumps are installed on both the water collection pipe and the water outlet pipe.

[0008] Furthermore, the motor is fixedly connected to the bottom of the fishpond, and the output end of the motor passes through the bottom wall of the fishpond and is fixedly connected to the lower end of the rotating shaft.

[0009] Furthermore, each of the water outlets is equipped with a valve.

[0010] This utility model has the following advantages compared with the prior art:

[0011] 1. This utility model, by setting a rotating shaft and fixing a scraper to the rotating shaft, and rotating a brush, can clean the bottom of the fish pond. By setting a filter plate at the bottom of the fish pond, it can prevent fish from flowing out through the lower outlet during cleaning and water changing, which would have a significant impact on the fish and reduce their survival rate. By setting a rotating sleeve to cooperate with the rotating shaft and the brush, it can control the brush and scraper to rotate in different directions at the same time, achieving a better cleaning effect. By setting a filter box, the wastewater in the fish pond can be filtered and then flowed into the fish pond through the outlet pipe for reuse, avoiding waste of water resources.

[0012] 2. This utility model features a bearing rotatably connected to a rotating shaft, with a filter plate fixedly connected to the outer ring of the bearing. This bearing secures the filter plate, preventing wear between the rotating shaft and the filter plate. A valve at the outlet allows for control of the water exchange rate, reducing workload and extending the equipment's lifespan. Attached Figure Description

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

[0020] like Figures 1 to 5 The illustrated fishpond wastewater cleaning and recycling device includes a fishpond 1. To recycle wastewater and prevent water waste, a filter box 2 is fixedly connected to the side wall of the fishpond 1. For automatic cleaning, a rotating shaft 3 is rotatably connected to the bottom of the fishpond 1. The rotating shaft 3 is driven by a motor 12. To remove impurities that fall to the bottom of the fishpond 1, a scraper 4 is fixedly connected to one side of the bottom of the rotating shaft 3. To control the brush 6 to move in opposite directions with the scraper 4, a protrusion 10 is fixedly connected to the top of the rotating shaft 3. To support the filter plate 5, a bearing 11 is rotatably connected to the rotating shaft 3 above the scraper 4. The outer ring of the bearing 11 is fixedly connected to the filter plate 5. The other side of the filter plate 5 is fixedly connected to the inner wall of the fishpond 1. To drive the brush 6 to rotate, a rotating sleeve 9 is rotatably connected to the top of the rotating shaft 3. The protrusion 10 cooperates with the rotating sleeve 9. When the rotating shaft 3 rotates counterclockwise, the protrusion 10 does not cooperate with the rotating sleeve 9. In coordination, the brush 6 does not rotate with the rotating sleeve 9. When the rotating shaft 3 rotates clockwise, the protrusion 10 and the rotating sleeve 9 mesh with each other, and the brush 6 rotates with the rotating shaft 3. In order to increase the force-bearing area, brackets 8 are symmetrically fixedly connected to the left and right sides of the rotating sleeve 9. A connecting frame 7 is fixedly connected to the other end of the bracket 8. The brush 6 is fixedly connected to the bottom surface of the connecting frame 7. The lower end of the brush 6 contacts the upper end of the filter plate 5. In order to discharge sewage in time, several water outlets 13 are opened at the bottom of the fish pond 1. A water collection pipe 14 is fixedly connected to the other end of the water outlet 13. The water collection pipe 14 connects all the water outlets 13 together. The output end of the water collection pipe 14 is connected to the bottom of one side of the filter box 2. A water outlet pipe 16 is fixedly connected to the top of the other side of the filter box 2. Sewage enters from the bottom right side of the filter box 2, passes through three layers of filtration, and flows out from the top left side, purifying the sewage and reusing water resources. The output end of the water outlet pipe 16 is located above the fish pond 1.

[0021] To ensure that the brush 6 does not rotate arbitrarily with the rotating shaft 3, a groove 17 is provided in the middle of the rotating sleeve 9. A retractable protrusion 18 is hinged in the middle of the groove 17. There are two symmetrical protrusions 18, corresponding to the positions of the protrusions 10. One end of the protrusion 18 is hinged and is flush with the surface of the groove 17, while the other end protrudes from the surface of the groove 17 through spring support. When the rotating shaft 3 rotates counterclockwise, the protrusions 10 push the protruding end of the protrusions 18 into the groove 17 as they pass through the protrusions 18. When rotating clockwise, the protrusions 10 and 10 engage and lock together. The brush 6 is driven to rotate through the protrusions 18, with the protrusions 18 and 10 working together.

[0022] In order to filter the sewage generated in fish pond 1 and avoid water waste, three layers of filter screen are set in filter box 2, which are arranged from right to left as sand layer, filter cloth layer and activated carbon layer.

[0023] It should be noted that each filter screen in filter box 2 has a cleaning port to facilitate the timely removal of impurities collected in filter box 2, thereby improving the filtration effect.

[0024] In order to achieve the recycling of wastewater, water pumps 15 are installed on both the water collection pipe 14 and the water outlet pipe 16.

[0025] In order to provide power to the rotating shaft 3 and realize the automation of the device, the motor 12 is fixedly connected to the bottom of the fish pond 1, and the output end of the motor 12 passes through the bottom wall of the fish pond 1 and is fixedly connected to the lower end of the rotating shaft 3.

[0026] In order to control the outflow and circulation rhythm of sewage, valves are installed on all outlets 13.

[0027] The specific working process of this utility model is as follows:

[0028] When fish produce excessive fish waste during the breeding process, causing the water in fishpond 1 to become cloudy and requiring cleaning, first, control motor 12 to rotate clockwise. At this time, protrusion 10 engages with protrusion 18, and protrusion 18 drives rotating sleeve 9 to rotate, thereby driving the brush to rub and clean the upper surface of filter plate 5. The impurities and fish waste attached to filter plate 5 fall through filter plate 5 to the bottom of fishpond 1. At the same time, scraper 4 slowly scrapes up the dirt at the bottom of fishpond 1 and loosens it, following the rotating shaft 3. Then, reverse motor 12 and increase the speed of motor 12, while opening the water outlet 13. The valve and water pump 15 at the bottom of the fish pond 1 scrape off the impurities and fish feces and absorb them with the water pump 15, sending the wastewater to the filter box 2. After being filtered by the three filter layers in the filter box 2, the water is sent into the fish pond 1 from the top for water resource recycling. When the wastewater at the bottom is discharged, the valve, water pump 15 and motor 12 are closed to complete the cleaning and recycling process of wastewater in the fish pond 1. Following the above steps to clean and recycle wastewater in the fish pond 1 can save a lot of time and manpower, avoid water waste, and reduce costs.
