Wind power generation blade device with ice removing capacity

Abstract

The invention discloses a wind power generation blade device with ice removing capacity. The device comprises a wind power generation blade and a front edge wind adjusting mechanism; the front edge wind adjusting mechanism is mounted in the wind power generation blade; the wind power generation blade comprises a blade shell; a back edge web is mounted at the top of the inner wall of the blade shell; a front edge web is mounted on the inner wall of the blade shell and positioned under the back edge web; and a back edge wind baffle plate is mounted on the right side of the back edge web. Throughcooperation of the back edge web, the front edge web, the back edge wind baffle plate, a front edge blade tip web, a blade tip ventilation hole, a ventilation pipe, a front edge wind baffle plate, aheating ventilation device, a wind hole adjusting pressure plate, an adjusting wind hole and a fixed bolt, the wind power generation blade device with the ice removing capacity is realized, the problem of incapability of directly arranging heating elements in a blade tip area of a wind power blade for heating and ice removal is solved, and the problems of higher wind pressure and higher flowing speed of a circulating system when a large-size and large-prebent blade adopts a traditional air heat circulating structure are solved.

Description

technical field [0001] The invention relates to the technical field of anti-icing and deicing technology for blades of wind power generating sets, in particular to a wind power generating blade device with deicing capability. Background technique [0002] Wind turbines are usually installed in areas with high altitude, low temperature, high humidity, and frequent thunderstorms. Especially in winter, with the decrease of temperature and increase of humidity, the outer surface of wind turbine blades is very easy to freeze, and the ice on the blade surface will often It causes vibration or power factor distortion of the turbine unit and endangers the operation of the unit. Therefore, the unit must be shut down after freezing, causing a large amount of power generation loss to the wind farm. [0003] The deicing of the blades of the existing wind turbines is mainly realized by adding heating elements inside or outside the blades to heat the blades. Generally, there are technical...

Problems solved by technology

[0002] Wind turbines are usually installed in areas with high altitude, low temperature, high humidity, and frequent thunderstorms. Especially in winter, with the decrease of temperature and increase of humidity, the outer surface of wind turbine blades is very easy to freeze, and the ice on the blade surface will often Cause vibration or power factor distortion of the turbine unit and endanger the operation of the unit, so the unit must be shut down after freezing, causing a large amount of power loss to the wind farm

[0003] The deicing of the blades of the existing wind turbines is mainly realized by adding heating elements inside or outside the blades to heat the blades. Generally, there are technical routes such as gas heating and electric heating, and the structure of the conventional gas heating deicing system is difficult to apply Large size and large pre-curved blades have a small scope of application, which is not conducive to widespread promotion and popularization. Therefore, we provide a wind power generation blade device with deicing ability
