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

A wind turbine that can be started and stopped by wind force disclosed in the present invention includes a main body, a wind shaft is rotatably provided at the center of the end face of the main body, and turbine blades are fixedly arranged in an annular array on the outer circular surface of the wind shaft. There is a start-stop cavity inside the shaft, and a generator is fixed in the lower wall of the start-stop cavity. The right side is provided with a fan device, the fan device is provided with a fan power connected to the wind shaft, and the upper left side of the start-stop cavity is provided with a friction device. The present invention drives the fan to fight through the wind, and then drives the turbine blades to start At the same time, the rotation of the fan can also convert kinetic energy into electrical energy. At the same time, the reverse wind force overcomes the rotation of the fan, and combines friction to stop the rotation of the turbine blades, which greatly reduces the friction loss caused by friction deceleration.

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...
