[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The purpose of this invention is to provide an underwater reoxygenation device to solve the technical problems existing in the prior art, which can oxygenate the bottom of the water.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figure 1 As shown, this embodiment provides an underwater reoxygenation device, including a pumping device, a floating container, a water supply pipe 2, and a weight 3. The floating container is located on the water surface and can be a basin-shaped, cylindrical, or other shaped container. The floating container is made of a lightweight material, such as wood, as long as it can float on the water surface. The first end of the pumping device is located below the water surface, and the second end is located above the floating container. The pumping device delivers water from below the water surface to the upper inlet of the floating container. The upper end of the water supply pipe 2 is connected to the lower end of the floating container, and the weight 3 is fixed to the lower end of the water supply pipe 2. The length of the water supply pipe 2 is set according to the actual depth of the water layer. The weight 3 is located at the bottom of the water layer 12 and above the mud layer 13, and the weight 3 does not block the lower end of the water supply pipe 2. Those skilled in the art can also set a controller and electrically connect the pumping device to the controller, thus enabling remote control of the pumping device's start-up.

[0025] When in use, start the pumping device. The first end of the pumping device draws the oxygen-enriched water on the water surface into the floating container. Then, the oxygen-enriched water in the floating container flows into the bottom of the water through the water supply pipe 2, thereby increasing the oxygen content at the bottom of the water.

[0026] The weight 3 serves two purposes: firstly, it secures the floating container, preventing it from drifting away with the current, thus acting as an anchor. Secondly, it prevents water from the water pipe 2 from flowing directly to the mud layer 13 at the bottom, thereby avoiding agitation and pollution. In this embodiment, the weight 3 is a fixing plate, which can be made of metal or other materials, as long as it can sink to the bottom. The fixing plate is tied to the bottom of the water pipe 2 with ropes, and the distance between the fixing plate and the bottom of the water pipe 2 is 10-20 cm. The cross-section of the fixing plate is larger than that of the water pipe 2, so that when water flows out of the water pipe 2, it can all impact the fixing plate and then flow away from the gap between the water pipe 2 and the fixing plate.

[0027] In order to prevent garbage or other debris on the water surface from being drawn into the water supply pipe 2, in this embodiment, the floating container is a funnel 1. Furthermore, a filter screen can be installed in the funnel 1, as long as it can filter garbage and prevent the water supply pipe 2 from being blocked.

[0028] In this embodiment, the pumping device includes a water pump 4, an inlet pipe 6, and an outlet pipe 5. The first end of the inlet pipe 6 is below the water surface, and the second end of the inlet pipe 6 is fixedly connected to the first end of the water pump 4. The first end of the outlet pipe 5 is fixed to the second end of the water pump 4, and the second end of the outlet pipe 5 is located at the upper inlet of the funnel 1. In use, the operator turns on the water pump 4, or the water pump 4 can be remotely controlled via a controller. The oxygen-enriched water at the water surface enters from the first end of the inlet pipe 6, passes through the water pump 4, and finally flows into the funnel 1 from the second end of the outlet pipe 5.

[0029] Furthermore, in this embodiment, the water pump 4 is an axial flow pump. Those skilled in the art can also replace the water pump 4 with other types of water pumps 4 according to actual needs, as long as they can perform the function of pumping water.

[0030] Example 2

[0031] This embodiment provides an underwater reoxygenation device, whose structure is basically the same as that in Embodiment 1, except that:

[0032] In this embodiment, the pumping device includes an air compressor 7, an air outlet pipe 9, and a U-shaped pipe 10. The air outlet of the air compressor 7 is fixed to the first end of the air outlet pipe 9. The first end of the U-shaped pipe 10 is located 10-20 cm below the water surface. The second end of the U-shaped pipe 10 is connected to the bottom of the funnel 1. It should be noted that the bottom of the funnel 1 is sealed except for the upper end of the water delivery pipe 2, which has a filter screen. The second end of the air outlet pipe 9 extends downwards from the upper end of the funnel 1 into the second end of the U-shaped pipe 10. During use, the air compressor 7 is manually started or remotely controlled by a controller. The air compressor 7 injects gas into the second end of the U-shaped pipe 10 through the air outlet pipe 9. According to the principle of air lifting, the density at the second end of the U-shaped pipe 10 decreases, causing the water in the first end of the U-shaped pipe 10 to flow towards the second end. This air lifting process is also an aeration process. Finally, the water flows from the second end of the U-shaped pipe 10 into the funnel 1 and then out through the water delivery pipe 2.

[0033] Furthermore, this embodiment also includes a partition 11, which is fixed inside the funnel 1. The height of the partition 11 is adjustable, and the height of the partition 11 is lower than the height of the funnel 1. The partition 11 divides the funnel 1 into a left cavity and a right cavity. The second end of the U-shaped tube 10 is located at the bottom of the left cavity, and the upper end of the water delivery pipe 2 is located at the bottom of the right cavity. In use, as the amount of oxygen-enriched water flowing in from the U-shaped tube 10 gradually increases, the liquid level in the left cavity gradually rises. When the liquid level is higher than the height of the partition 11, the oxygen-enriched water in the left cavity flows into the right cavity, and then the oxygen-enriched water flows out through the water delivery pipe 2.

[0034] In this embodiment, a gas storage tank 8 is also included. The gas storage tank 8 is fixed on the gas outlet pipe 9 and mainly serves to stabilize the system pressure.

[0035] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
