At present, wind energy is mainly used for power generation and heating. In fact, the utilization efficiency of wind energy for wind energy heating is higher than that of wind power generation. Most of the existing small and medium-sized mechanical energy direct-driven wind heating units are composed of vertical axis wind turbines and compressors. There is a lack of adjustment devices between the compressor and the vertical axis wind turbine, which leads to the imperfect performance of the wind heating unit. Under the influence of ambient wind, the mechanical energy output power of the vertical axis wind turbine is not stable, resulting in the compressor input power cannot be stabilized within the appropriate working power range, thereby affecting the working efficiency and working life of the compressor. At present, a stirring heater is generally added as an adjustment device on the basis of a traditional wind heating unit to divert part of the output power of the wind heating machine, trying to control the input power flowing into the compressor to be stable within a reasonable working range, but the power of the existing stirring heater is fixed and cannot adapt to different wind speed environments. The wind heating machine has low mechanical energy utilization and large losses, and it is still difficult to match the working power of the compressor well, resulting in low heating efficiency.

[0027] The purpose of the present invention is to provide a liquid stirring wind power heating unit and an adaptation method thereof, which can improve the heating efficiency of the wind power heating unit and is of great significance to achieving energy conservation and emission reduction.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1 to 3As shown, a liquid stirring wind-powered heating unit provided by an embodiment of the present invention comprises: a vertical axis wind turbine 5, a coupling 5, a stirring heater 6, an energy storage device and a compressor 13, wherein the vertical axis wind turbine comprises a fan blade 1, a transmission long shaft 2 and a speed increaser 4, and the stirring heater 6 comprises a stirring barrel 601 and a baffle 602, a rotor blade 603 and a stirrer main shaft 604 arranged in the stirring barrel 601, wherein the baffle 602 is arranged on the inner wall of the stirring barrel 601, and the rotor blade 603 is arranged on the stirrer main shaft 604, and the rotor blade 603 is relative to the stirring barrel 601. The radial direction of the agitator main shaft is deflected clockwise by an angle α or counterclockwise by an angle α, and the fan blade 1 is installed at the upper end of the transmission long shaft 2. The lower end of the transmission long shaft 2 passes through the speed increaser 4, the coupling 5 and the stirring heater 6 in sequence and is connected to the compressor 13. The agitator main shaft 604 is fixed to the transmission long shaft 2 through the coupling 5. The energy storage device includes a heat collection inlet pipe 8, a heat collection outlet pipe 7, and a hot water storage tank 9. The hot water storage tank 9 is connected to the stirring heater 6 through the heat collection inlet pipe 8 and the heat collection outlet pipe 7 respectively, and the stirring heater 6 is filled with liquid working medium. Among them, a circulation pump is arranged inside the heat collection water inlet pipe 8; an insulation layer is arranged outside the stirring heater 6, and an insulation layer may also be arranged outside the hot water storage tank 9; the liquid stirring wind power heating unit also includes a base tower 3, and the base tower 3 is erected outside the speed increaser 4, the coupling 5 and the stirring heater 6; the liquid stirring wind power heating unit also includes a heat dissipation device, and the heat dissipation device includes a heat dissipation water inlet pipe 10, a heat dissipation water outlet pipe 11 and a radiator 12, and the radiator 12 is connected to the hot water storage tank 9 through the heat dissipation water inlet pipe 10 and the heat dissipation water outlet pipe 11 respectively; a circulation pump is arranged inside the heat dissipation water inlet pipe 10; Figures 4a to 4d As shown, when the rotor blade 603 is working, the angle α is set to 0°, 15°, 30° or 45°, and can also be set to other angles according to actual needs.

[0030] The working principle is: the ambient wind drives the fan blades of the vertical axis wind turbine to rotate. On the one hand, the main shaft of the agitator is driven to rotate through the transmission long shaft. The rotor blades of the stirring heater stir the liquid working medium to make turbulent motion, completing the transformation of mechanical energy into thermal energy. This part of the thermal working medium can enter the hot water storage tank for storage and utilization; on the other hand, the mechanical energy of the transmission long shaft is diverted, and part of the excess mechanical energy drives the compressor to work. When the wind is strong, the stirring heater stores the excess output power of the vertical axis wind turbine in the form of thermal energy in the hot water storage tank; when the wind is weak, the vertical axis wind turbine and the stirring heater replenish energy to the compressor.

[0031] In order to ensure that the working power of the compressor is stable within a certain range, the power of the stirring heater needs to change with the output power of the wind turbine. The stirring heater changes its own working power by changing the rotation angle of the rotor blades.
