Automatic retractable wind power generating device with gravity sliding rings

Abstract

The invention belongs to the technical field of wind power generation, and provides an automatic retractable wind power generating device with gravity sliding rings. The automatic retractable wind power generating device aims to solve the problem that an existing sailing boat type wind power generating device cannot ensure effective power generation due to the fact that a sailboard of the device is fixed in position and stress direction. The automatic retractable wind power generating device comprises a reduction gear box, a power generator, a supporting frame, a rotating disc and a plurality of fan impellers, wherein the fan impellers are arranged on the supporting frame in parallel, the lower end of the supporting frame is fixedly mounted on the rotating disc, a rail is arranged under the rotating disc in a matched mode, and universal wheels at the bottom of the rotating disc roll along the rail; and each fan impeller comprises a framework, canvas and a rotating shaft, wherein the framework is mounted on the rotating shaft and rotates around the framework, one end of the canvas is fixedly mounted at the end of the radial framework, and the other end of the canvas is slidably mounted on the radial framework through the multiple sliding rings. According to the automatic retractable wind power generating device, the fan impellers are made to rotate by the pressure difference between the canvas above the rotating shafts and the canvas below the rotating shafts, and thus power is generated; and external operation conditions of the device are wider, and the power generating function is better guaranteed.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a gravity slip ring automatic retractable wind power device. Background technique [0002] Wind energy is the energy generated by a large amount of air flow on the earth's surface. It is a non-polluting renewable energy source. It does not need to invest in raw material costs, and there is no waste residue to be discharged. It is inexhaustible and inexhaustible. The wind resources on the earth are very rich, but The utilization rate of natural wind power by human beings is very low, and most of the energy is lost in vain. [0003] Existing wind power devices have a variety of structures, including propeller structure, turbine structure and sailing structure, all of which can realize wind power conversion to a certain extent, while the existing sailing wind power devices simply use the wind effect of the canvas to generate power, as shown in the patent T...
