Multifunctional temperature control heating system

Abstract

The invention relates to the technical field of temperature control of wind power generators. In order to solve the problem in the prior art that the rotation speed of the rotor shaft of the generator cannot be reduced due to the uncontrollable natural wind force, the high temperature phenomenon of the permanent magnet cannot be eliminated; a multi- The functional temperature-controlled heating system includes a casing and a generator for driving the blades to rotate. The generator includes a rotor and a plurality of permanent magnets; a sliding groove is arranged on the inner wall of the rotor yoke, and the opening of the sliding groove is set toward the inside of the rotor yoke; the permanent magnet It is slidingly connected with the sliding groove, and the side wall at the bottom of the sliding groove is provided with a driving structure. The limiting piece enters into the sliding groove and pushes the permanent magnet to slide toward the inside of the rotor yoke, and the limiting piece returns to the connecting groove after the temperature of the rotor yoke is lowered. The invention can reduce the probability of demagnetization of the permanent magnet.

Description

technical field [0001] The invention relates to the technical field of wind power generator temperature control, in particular to a multifunctional temperature-controlled heating system. Background technique [0002] One of the more readily available clean energy sources is wind power, which converts wind energy into electricity. When working, the wind wheel rotates under the action of wind force, which converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. After the wind wheel shaft rotates, the gear transmission structure drives the generator to rotate and generate electricity. In order to reduce the impact of the surrounding environment on wind power, wind turbines are usually set up in open fields, where there are few buildings in the surrounding environment, and the generator is still at a high altitude, so the wind will not weaken due to the influence of buildings. Phenomenon. In this way, when the weather is cold, the temperature...
