Resistance type wind power blade device capable of being automatically opened and closed

Abstract

The invention relates to a resistance type wind power blade device capable of being automatically opened and closed. The resistance type wind power blade device comprises a pair of round guide rail rotation shafts and a plurality of resistance type blade modules capable of rotating on the round guide rail rotation shafts, wherein the resistance type blade modules are mutually spaced by a certain angle. Each resistance type blade module comprises a frame body, blades and a base, the frame is of a semi-arc cylindrical shape and is at least provided with one blade opening, and the blades can move between the closing position covering the blade opening and enabling the swing end to get close to the frame body and the opening position enabling the swing end to get away from the frame body. The resistance type wind power blade device is simple in structure and convenient to assemble, the wind power blades can be automatically opened and closed according to the speed and the direction of natural wind, and therefore the stable rotation speed range can be automatically adjusted. Through the double round guide rail rotation shafts, the speed increase effect is realized, the rotation speed of a power generator is increased, the stability and the safety of a windmill system device are improved, and the utilization rate of the wind energy is greatly increased.

Description

technical field [0001] The invention relates to a wind blade device, in particular to a resistance type automatic opening and closing wind blade device. Background technique [0002] At present, with the continuous enhancement of people's awareness of environmental protection, the use of new energy will definitely become a trend. As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Because wind power resources are inexhaustible, using wind power to generate electricity can save conventional energy such as coal and oil, and has no waste gas emissions, reduces environmental pollution, does not require too much manpower, and has low operating costs. Prospects. [0003] Among them, the blade is an important component that converts the kinetic energy of the wind into mechanical energy, and is the key core component of the wind power generation device. Therefore, the design, quality and performance of the blades are...

Problems solved by technology

However, since the magnitude and direction of the wind force are constantly changing, when the wind speed is too high and the resistance-type blades are at a high speed, the resistance-type blades will generate resistance against rotation for the entire wind power generation system, thereby reducing the rotation efficiency and causing power generation efficiency. reduction of

And when the wind speed is too high, the blades are also prone to wear and damage, which weakens the safety of the wind turbine system device; it is often necessary to stop the blades from working to avoid damage to the wind turbine system device, which greatly reduces the utilization factor of wind energy
