Problems solved by technology

[0002] Wind turbines can convert wind power into electricity, and the power generation efficiency of vertical wind turbines is higher than that of horizontal turbine generators, so vertical wind turbines gradually replace horizontal turbine generators, but vertical wind turbines cannot be started directly under the wind, so they need assistance power assist start
Ordinary vertical wind turbines are generally started by electricity, and the turbine is stopped by resistance or friction to decelerate and stop, which not only consumes energy, but also has large friction losses and high maintenance costs

Abstract

The invention discloses a wind turbine capable of being started and stopped by means of wind power. The wind turbine comprises a body. A wind power shaft is rotationally arranged at the center of theend face of the body. Turbine blades are fixedly arranged at the outer circumferential face of the wind power shaft in an annular array tangential mode, a starting and stopping cavity is formed insidethe wind power shaft, an electricity generator is fixedly arranged inside the lower wall of the starting and stopping cavity, the lower end of the wind power shaft extends into the starting and stopping cavity and is in power connection with the upper end of the electricity generator, a fan device is arranged at the right side of the starting and stopping cavity, a fan in power connection with the wind power shaft is arranged inside the fan device, and a friction device is arranged above the left side of the starting and stopping cavity. Wind power is used for driving the fan to combat, then,the turbine blades are driven to start rotating, meanwhile, the fan rotates to convert kinetic energy into electric energy, reverse wind power is used for overcoming rotation of the fan at the same time, rotation of the turbine blades is stopped in cooperation with friction, and friction losses caused by friction speed reduction are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of turbines, in particular to a wind turbine that can be started and stopped by wind power. Background technique [0002] Wind turbines can convert wind power into electricity, and the power generation efficiency of vertical wind turbines is higher than that of horizontal turbine generators, so vertical wind turbines gradually replace horizontal turbine generators, but vertical wind turbines cannot be started directly under the wind, so they need assistance Power assists it in starting. Ordinary vertical wind turbines are generally started by electric power, and the turbine is stopped by resistance or friction to decelerate and stop, which not only consumes energy, but also has large friction losses and high maintenance costs. The present invention illustrates a device capable of solving the above-mentioned problems. Contents of the invention [0003] technical problem: [0004] Ordinary vertical wind t...
