[0002] Rivers are an important part of the human living environment. However, due to their characteristics such as being easily polluted, having a small water environment capacity, and poor water self-purification ability, they are very likely to become the recipients of domestic sewage, rainwater, and garbage of residents, resulting in a large consumption of dissolved oxygen in the water body, causing the water body to be oxygen-deficient and showing a black and smelly state, and making the entire ecological system in crisis.

[0003] Therefore, it is necessary to repair the river ecology. Currently, the common device for river ecological governance is an ecological floating bed. A patent with a publication number of CN214141770U is disclosed in the prior art. This solution includes an ecological floating bed body and a limiting groove. One side of the ecological floating bed body is fixedly installed with a fixed clamping block. Both sides inside the fixed clamping block are provided with first fixed grooves. A clamping block is fixedly installed inside the first fixed grooves. The other side of the ecological floating bed body is provided with a second fixed groove. Both sides inside the second fixed groove are provided with third fixed grooves. A limiting plate is movably installed inside the third fixed grooves.

A connecting piston is fixedly installed at the bottom of the limiting spring.

[0004] In the process of using the prior art including the above patent, the deficiencies of this technology have gradually emerged: the ecological floating bed usually uses aquatic plants to repair the river water body, but the repair speed of the aquatic plants to the river water body is slow and the repair effect is poor.

[0050] The working principle of this device is as follows:

[0051] When pumping the water body of the river channel 2 into the repair pool 17, first open the low-level water inlet pipe 21. The water in the river channel 2 enters the repair pool 17 through the low-level water inlet pipe 21. When the water surface in the repair pool 17 is at the same height as the water surface in the river channel 2, close the low-level water inlet pipe 21 and open the water pump 19. The water in the river channel 2 enters the repair pool 17 through the high-level water inlet pipe 20 and the water outlet pipe 18. The repair pool 17 fixedly arranged under the ground 1 is not only not affected by the rainy season, but also when the water level of the river channel 2 rises sharply during the rainy season, the water in the river channel 2 can be pumped into the repair pool 17, thus achieving the functions of flood control and flood storage. And through the set low-level water inlet pipe 21, the functions of energy conservation and environmental protection can be realized, improving the practicability of the device;

[0052] Before repairing the water body in the repair pool 17, add treatment agents and water into the mixing tank 11. The control motor 9 drives the driving shaft 12 and the stirring blades 13 to rotate. During the rotation of the stirring blades 13, the treatment agents and water in the mixing tank 11 can be evenly mixed, effectively preventing the deposition of treatment agents and further improving the practicability of the device;

[0053] When repairing the water body in the repair pool 17, the driving motor 31 drives the driving gear 32 to rotate, which in turn drives the driven gear 28, the outer rotating pipe 26 and the inner rotating pipe 27 to rotate, thereby driving the liquid discharge pipe 23, the mixing blades 24, the annular pipe 37 and the aeration disc 38 to rotate. At the same time, the air suspension aerator 7 compresses and conveys the external air, and the compressed air enters the outer rotating pipe 26 after passing through the air inlet pipe 8 and the outer fixed pipe 29 in sequence. With the cooperation of the air vent pipe 35 and the connecting pipe 36, the compressed air in the outer rotating pipe 26 enters the annular pipe 37 and is discharged to the bottom of the repair pool 17 by the aeration disc 38. The liquid extraction pump 14 extracts and conveys the treatment agent in the mixing tank 11, and the treatment agent enters the liquid discharge pipe 23 after passing through the liquid conveying pipe 15, the inner fixed pipe 30 and the inner rotating pipe 27 in sequence, and is discharged into the repair pool 17 through the liquid discharge holes on the liquid discharge pipe 23. During the rotation of the mixing blades 24, the air, the repair agent and the water body in the repair pool 17 can be mixed, so as to quickly repair the water body. The repaired water body is pumped by the drainage pump 4 and enters the river 2 through the water extraction pipe 5 and the drainage pipe 3, realizing the function of quickly repairing the water body of the river 2, and having a good repair effect and improving the water quality of the water body of the river 2.
