Inching brake self-protection type small wind driven generator

Abstract

The invention discloses a snub self-protection type small wind driven generator, and belongs to the field of wind driven generators, the snub self-protection type small wind driven generator comprises a generator body, the generator body comprises a machine shell and a rotating shaft connected with fan blades, a speed limiting ring is fixedly embedded in the side wall of the machine shell, and the rotating shaft penetrates through the speed limiting ring; by improving an existing wind driven generator, the wind driven generator has the functions of automatically and manually starting and stopping a safety device, a magnetic block repels a second friction plate outwards by pulling a starting rope, the second friction plate and a first friction plate rub each other, and therefore the speed of a rotating shaft is reduced, and safe operation of the generator in strong wind weather is guaranteed; and the friction sleeve is additionally arranged on the side wall of the rotating shaft, and the friction plate I and the friction plate II are in intermittent contact by utilizing the principle that the centrifugal force is increased at a high rotating speed, so that the purpose of speed reduction is achieved, the generator realizes self-protection under the condition that people forget to start the starting rope, and the service life and the operation stability of the generator are effectively improved.

Description

technical field [0001] The invention relates to the field of wind power generators, and more specifically relates to a point brake self-protection type small wind power generator. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. Wind turbines are generally composed of components such as wind rotors, generators (including devices), steering devices (tail fins), towers, speed-limiting safety mechanisms, and energy storage devices. The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of the wind, which converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft, and the generator rotates to generate electricity under the drive of the wind rotor shaft. In a broad sense, wind energy is also solar energy, so it can also be said that a wind generator is a thermal ener...

Problems solved by technology

[0004] At present, there are safety devices inside the wind turbines to prevent damage to the generator due to excessive speed in windy weather, but the existing safety devices are generally not reliable, and manual control is required, and it is inevitable to forget in actual use. and it is not convenient to activate the safety device in windy weather
