[0032] An energy-saving box 7 is also fixed inside the box body 1 by screws. An inverter 8 and a power storage module 9 are arranged inside the energy-saving box 7. The power storage module 9 is connected to the solar photovoltaic panel 10 and the small wind turbine 11 on the top of the box body 1 by wires.

[0033] A remote controller 12 is also fixed inside the box body 1, and connecting ears 14 for installing connecting ropes 13 are provided on both sides of the box body 1. L-shaped support plates 15 are fixed to both sides of the box body 1 by screws, and annular floats 16 are provided at the upper and lower ends of the L-shaped support plates 15. Considering that aerators are generally used to increase the oxygen content in sewage in sewage pools to promote microbial growth, thereby achieving organic matter degradation and water purification, common tubular aerators need to be assembled with mounting frames, and the installation process is relatively cumbersome. In addition, since the aerator needs to work all day, it has the disadvantage of high energy consumption. When installing the utility model, there is no need to lay a large number of pipes and then connect the aeration pipe 5 for use. It only needs to be placed in the wastewater, and the box body 1 of the device will The annular buoy 16 floats on the wastewater surface, and the counterweight ring 21 is used to ensure stability. The device only needs to be fixed with the connecting rope 13 and the connecting ear 14 and then tied to the side of the wastewater pool. The installation is convenient. Considering the energy saving problem, the device will convert light energy and wind energy into electrical energy through the solar photovoltaic panel 10 and the small wind turbine 11, and store it in the power storage module 9 for use as backup energy. Therefore, backup energy is provided for the device, and the consumption of electric power resources is reduced, thereby achieving the effect of energy saving. In order to ensure the wind power generation effect, the remote controller 12 can control the reduction motor 24 to control the rotation of the rotating support 26, so that the small wind turbine 11 at the upper end of the sleeve rod 30 is always on the windward side.

[0034] Among them, the two annular buoys 16 are fixed to the L-shaped support plate 15 through a U-shaped hoop 17. Studs 19 for tightening nuts 18 are fixed on the front and rear sides of the L-shaped support plate 15, and the studs 19 penetrate into the reserved groove 20 in the middle of the U-shaped hoop 17. The U-shaped hoop 17 is provided to fix the annular buoys 16 at the upper and lower ends of the L-shaped plate. After the U-shaped hoop 17 is stuck in the middle of the two annular buoys 16, the reserved grooves 20 of the two U-shaped hoops 17 are used to be sleeved on the outside of the studs 19, and then the nuts 18 are tightened to fix the U-shaped hoop 17.

[0035] Among them, the bottom of the box body 1 is integrally formed with a docking seat 22 for threaded connection of the counterweight ring 21, and the inside of the counterweight ring 21 is provided with a counterweight filler 23. In order to increase the stability of the box body 1 when floating in the water, the counterweight ring 21 is designed. It can be seen from the accompanying drawings that the bottom of the counterweight ring 21 is similar to a conical structure, so that the box body 1 can obtain a certain stability in the water. Combined with the annular buoy 16, it effectively avoids the situation where the box body 1 tilts on both sides due to water ripples.

[0036] Among them, the remote controller 12 is connected to the oxygen pump and the reduction motor 24 circuit through a wire. The reduction motor 24 is fixed to the inner top of the box body 1 through a chassis 25, and the output shaft of the reduction motor 24 is fixedly connected to the bottom rod of the rotating support 26 through a coupling. The chassis 25 and the middle of the box body 1 are penetrated with a clearance hole for the bottom rod of the rotating support 26 to pass through. A load-bearing ring 27 is fixed to the bottom of the rotating support 26, and a connecting seat 28 is sleeved on the outside of the load-bearing ring 27, and the connecting seat 28 is fixed to the upper end of the box body 1 through screws. Balls 29 are provided on the upper and lower surfaces of the side ends of the load-bearing ring 27. A sleeve rod 30 is fixed to the top of the rotating support 26. By setting the reduction motor 24, the rotating support 26 is driven to rotate. The rotation of the rotating support 26 can adjust the use angle of the small wind turbine 11 so that its blade part is on the windward side. The presence of the ball 29 reduces the friction force when the rotating support 26 rotates, making the angle adjustment smoother.

[0037] Among them, an inner cavity is opened at the upper end of the sleeve rod 30 for the rod part of the small wind turbine 11 to pass through, and the rod part of the small wind turbine 11 is fixed by a limit bolt 31 at the front end of the sleeve rod 30. By setting the limit bolt 31, the use height of the small wind turbine 11 is adjusted, thereby avoiding the use height of the small wind turbine 11 being too low, which causes the fan blades to contact the surface of the solar photovoltaic panel 10.

[0038] The solar photovoltaic panel 10 is fixed on the top of the box body 1 through a bracket 32 ​​, and the bracket 32 ​​is provided to install the solar photovoltaic panel 10 .

[0039] Among them, a protective cover 33 is fixed to the upper end of each aeration tube 5 through a positioning bolt 34, and through holes for installing a filter screen 35 are opened at equal intervals on the protective cover 33. The position of the filter screen 35 is set in a one-to-one correspondence with the position of the one-way nozzle 6 at the upper end of the aeration tube 5. By setting the protective cover 33, it is prevented that the debris in the sewage adheres to the surface of the one-way nozzle 6 to cause blockage, and in order to ensure the discharge of gas, a filter screen 35 for ventilation is set on the protective cover 33.
