specific Embodiment approach

[0007] Specific embodiments: The overall structure and working principle of the present invention will be described in detail in conjunction with the accompanying drawings.

[0008] Overall structure of the present invention: as attached figure 1 As shown, the described wind-guiding reinforced windmill blade: it consists of the main panel of the blade (1), a plurality of ribs (2) arranged on the leeward side of the main panel of the blade, and the ribs (2) arranged on the windward side of the main panel of the blade. It consists of a plurality of wind guiding beams (3), a blade installation nose bridge (4) arranged on the leeward side of the blade main panel, and a blade installation hole (5) arranged on the blade installation nose bridge. The wind-guiding reinforced windmill blade is characterized in that a plurality of reinforcing ribs (2) arranged on the leeward side of the main panel of the blade form a plurality of transverse air-guiding grooves with each other. The wind...

Abstract

The invention relates to an air-guide-type reinforcement-type wind turbine blade, belongs to the technical field of green energy, and aims at solving the technical problems that traditional wind turbine blades are not provided with air guide grooves, when air molecules beat the blades, the ejection direction is disperse, thrust force is small, the wind energy utilization coefficient is low, and the wind turbine blades are heavy and liable to get destroyed. To solve the technical problems, the air-guide-type reinforcement-type wind turbine blade consists of a main blade panel 1, a plurality ofreinforcement ribs 2, a plurality of air guide beams 3, blade installing nose ridges 4 and blade installing holes 5 and is characterized in that the reinforcement ribs 2 mutually constitute a plurality of transverse air guide grooves, and a plurality of air guide beams 3 mutually constitute a plurality of longitudinal air guide grooves. The air-guide-type reinforcement-type wind turbine blade is mainly used to convert wind energy into mechanical energy. According to the air-guide-type reinforcement-type wind turbine blade, by forming the air guide grooves in the leeward side and the windward side of the blade panel respectively, the strength of the blade is improved, the weight of the blade is lowered, the wind energy utilization coefficient is increased, and the purpose of converting gentle breeze into mechanical energy is achieved.

Description

technical field [0001] The invention belongs to the field of green energy, in particular to a wind-guiding reinforced windmill blade. Background technique [0002] The efficiency of a wind turbine mainly depends on the ratio of the wind-receiving area of ​​the blade to the blade weight. The greater the ratio of the wind-receiving area of ​​the blade to the blade weight, the higher the wind energy conversion rate of the wind turbine. The ratio of the wind area of ​​the blade to the weight of the blade is determined by the structure of the blade. ZL: 201110035161 as the patent number; ZL: 200910163134.4; ZL: 200610046196.3; ZL: 201120072211.8 patented technology, its main technical problem of described wind turbine blade is: do not arrange wind guide slot respectively on the leeward side and the windward side of the blade panel, As a result, the blades of the wind turbine are bulky and easily damaged, and when the air molecules hit the blades, the direction of ejection is sca...
