Brake protection device of wind driven generator

Abstract

The invention discloses a brake protection device of a wind driven generator, and belongs to the technical field of brake protection devices of wind driven generators. The brake protection device comprises two brake clamping rings, wherein a motor shaft is arranged between the two brake clamping rings, brake pads are arranged on the upper side and the lower side of the motor shaft, and fixing grooves are formed in the positions, corresponding to the brake pads, in the brake clamping rings. According to the brake protection device, a limiting mechanism, an arc-shaped sliding plate, a semi-ellipsoidal groove, a connecting strip, a pulling rod and a containing groove are arranged, wherein the limiting mechanism comprises a supporting block, a rotating shaft, a rotating knob, a fixing plate, afixing bolt, a rotating column, a limiting plate, a reinforcing limiting clamping block and a reinforcing limiting clamping groove; and under the mutual cooperation of the structures, the function that the brake pads are convenient to mount and dismount is achieved, so that the brake pads are convenient to replace after being aged after being used for a period of time, the subsequent working efficiency of the brake pads is effectively guaranteed, the structure is simple, the operation is convenient and fast, and the operability is high.

Description

technical field [0001] The invention belongs to the technical field of brake protection devices for wind power generators, and in particular relates to a brake protection device for wind power generators. 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. A wind turbine generally includes a wind wheel, a generator (including devices), a steering device (tail), a tower, and a limiter. The working principle of the wind turbine is relatively simple. The wind rotor rotates under the action of the wind. It converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft, and the generator rotates under the drive of the wind rotor shaft. Power generation, in a broad sense, wind energy is also solar energy, so it can also be said that a wind turbine is a thermal energy generator that uses the sun as a heat source and the at...

Problems solved by technology

[0004] The above-mentioned patents have the following problems: 1. The brake pad is fixedly connected inside the fixed groove. If it is used for a long time, it will age and the protection effect on the motor shaft will become poor; 2. The brake piston and the connection installation block need to be realized by multiple screws. It is more troublesome to fix between
