BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

The base 1 and the tower 20 are an integrated structure, and the base 1 is buried underground to improve the overall installation structure strength. Based on the hydraulic transmission system, the weight of the cabin 21 is reduced, the force on the tower is improved, and the starting wind speed of the wind turbine is low, and the adaptability to wind speed fluctuations is good.

The cooler 43 is connected to the heat exchange assembly 6. The compressor and hydraulic motor are well matched, ensuring the compressor's gas production rate. The use of an intercooling structure ensures stable operation of the compressor, reduces compressor power consumption, and allows water to fully absorb waste heat discharged during the compression process, improving the utilization rate of low-grade thermal energy.

The pneumatic diaphragm pump 13 is provided with an exhaust control valve. The pneumatic diaphragm pump 13 is provided with a pneumatic diaphragm pump diaphragm 14. The heat exchange component 6 is connected to the pneumatic diaphragm pump 13 through a pipeline, and a one-way check valve 15 is provided on the pipeline.
