However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Please see Figures 1-5This utility model provides a technical solution: a photovoltaic integrated circulating oxygenation device for mandarin fish farming, including an overall mechanism 1, with a set of auxiliary mechanisms 2 fixedly installed on the outer wall of the overall mechanism 1; the overall mechanism 1 includes a breeding box 101, with a sealing gasket 109 slidably connected to the inner wall of the breeding box 101, a first stainless steel filter screen 110 fixedly connected to the inner wall of the sealing gasket 109, a connecting plate 111 fixedly connected to the top of the first stainless steel filter screen 110, a connecting block 112 fixedly connected to both the front and back of the breeding box 101, a sliding rod 115 fixedly connected to the top of the connecting block 112, a top block 114 fixedly connected to the shaft end of the sliding rod 115, and a compression spring 113 sleeved on the outer wall of the sliding rod 115. Through the above components, the filter screen can be quickly disassembled and assembled, and the steps are relatively simple.

[0026] like Figure 2 As shown, a PLC controller 104 is fixedly installed on one side of the front of the breeding box 101, and a set of batteries 103 is fixedly installed on the outer wall of the breeding box 101. The PLC controller 104 is electrically connected to the components in order to control the opening and closing of the components.

[0027] like Figure 2 and Figure 3 As shown, a set of centrifugal pumps 105 are fixedly connected to the outer wall of the breeding tank 101. A second stainless steel filter screen 106 is fixedly connected to the inner wall of the breeding tank 101 at the position of the centrifugal pumps 105. A set of conveying pipes 102 are fixedly connected to the output end of the centrifugal pumps 105. The conveying pipes 102 are connected to the inside of the breeding tank 101. By setting the second stainless steel filter screen 106, the water entering the centrifugal pumps 105 can be filtered to block impurities and ensure the operation of the equipment.

[0028] like Figure 2 and Figure 3 As shown, aeration pipes 107 are installed through the bottom of the inner wall of the breeding box 101. An aerator 108 is fixedly installed on the front of the breeding box 101. The aerator 108 is connected to the interior of the aeration pipes 107. Through the aerator 108 and the aeration pipes 107, the purpose of oxygenation can be achieved.

[0029] like Figure 4 As shown, one end of the compression spring 113 is fixedly connected to the top of the connecting block 112, and the other end of the compression spring 113 is fixedly connected to the bottom of the top block 114, so that the two ends of the compression spring 113 are connected to ensure that it can be used normally in the future.

[0030] like Figure 4 As shown, a set of pressure plates 116 are fixedly connected to the outer wall of the top block 114. The top block 114 is slidably connected to the inner wall of the connecting plate 111. Through the pressure plates 116, it is convenient for the user to move the top block 114 connected to it downwards, so that the top block 114 can be separated from the connecting plate 111.

[0031] like Figure 5 As shown, the auxiliary mechanism 2 includes a fixed frame 201, on which solar panels 202 are fixedly installed. The solar panels 202 are tilted at an angle of 15 degrees. The solar panels 202 are connected to the battery 103 via an MPPT charger. Through the solar panels 202, solar energy can be converted into direct current through the photovoltaic effect, providing basic energy for the entire device.

[0032] The operating method and working principle of this device are as follows: First, the solar panel 202 of the auxiliary mechanism 2 is tilted at 15 degrees. Solar energy is converted into direct current through the photovoltaic effect and stored in the battery 103 via the MPPT charger. This power supplies equipment such as the PLC controller 104, centrifugal pump 105, and aerator 108. Solar energy is used preferentially during the day, while the battery 103 supplies power at night or on cloudy days, ensuring 24-hour system operation. After the aerator 108 is started, air is delivered to the bottom of the breeding tank 101 through the aeration pipe 107 and released in the form of microbubbles. As the bubbles rise, they dissolve oxygen, increasing the dissolved oxygen content in the bottom water. Simultaneously, this causes water to flow upwards, promoting water layer mixing and alleviating dissolved oxygen stratification. Meanwhile, when the centrifugal pump 105 draws water from the breeding tank 101, it first filters the water through the second stainless steel filter screen 106 at its inlet to block impurities and prevent damage to the pump body. The filtered water then flows through the delivery pipe 102. Returning to the top of the breeding tank 101, a circulation path is formed with bottom water pumping, filtration, and top water distribution, driving the exchange of water layers and accelerating the flow of suspended solids. The first stainless steel filter screen 110 is fixed by the connecting plate 111, slide rod 115, compression spring 113, and top block 114. The elasticity of the compression spring 113 causes the top block 114 to lock the connecting plate 111, thus fixing the filter screen. During maintenance, pressing the pressure plate 116 moves the top block 114 down and away from the connecting plate 111, allowing the filter screen to be quickly pulled out for cleaning or replacement. No tools are required, and the operation can be completed by a single person, greatly shortening the maintenance time. In addition, the timer program can be set through the control panel on the PLC controller 104 to start the aerator 108 and centrifugal pump 105 at timed intervals, realizing intelligent and precise control of oxygenation and circulation.

[0033] The PLC controller 104, battery 103, aerator 108, centrifugal pump 105, and solar panel 202 used in this application are all common equipment on the market and are known to those skilled in the art. In this application, the above equipment is used in a conventional manner without any improvement to its structure and function. Regarding their settings, installation, and electrical connection methods, those skilled in the art can debug and operate them according to the corresponding product instruction manuals, so they will not be described in detail here.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
