Wind power generation unit hub temperature control device

Abstract

The invention discloses a wind power generation unit hub temperature control device which comprises a hub, a fairing and a plurality of blades connected with the hub, wherein each of the hub and the blades is provided with a chamber; ventilation driving equipment is mounted in the chamber of the hub; the chamber of at least one blade is provided with an air ducting device distributed in the lengthof the blade; the air inlet or the air outlet of the ventilation driving equipment communicates with one end of the air ducting device; and the other end of the air ducting device communicates with the chamber of the blade. The wind power generation unit hub temperature control device is simple in structure, applicable, high in reliability, low in cost and convenient to mount and maintain, controls the air temperature of the chamber of the hub, ensures that the wind power generation unit is prevented from external invasion while ensuring that the air temperature in the hub is within the rangeof the normal running environmental temperature of all components, meets the using requirement of the wind power generation unit under the condition of low cost and ensures the quality reliability ofthe wind power generation unit.

Description

technical field

[0001] The invention relates to the technical field of temperature control in a hub of a wind power generating set, in particular to a temperature control device for a hub of a wind generating set. Background technique

[0002] A wind turbine is a device that converts wind energy into electrical energy. It generally consists of a tower, a nacelle and a wind wheel. The tower is generally used to support the nacelle to a high altitude. The wind rotor part mainly includes blades, hubs, shrouds, pitch control systems, etc. The wind rotor structure is a double-layer structure in form, and the outer layer is a shroud. Its function is mainly to prevent wind, rain, sand and air from entering the interior of the wind rotor and negatively affect the components inside the wind rotor. The inner layer is the hub, which is a thick metal layer, and its function is mainly to bear the load of the blade and the entire wind wheel. The related components of the pitch control s...
