Embodiment Construction

[0017] Below in conjunction with accompanying drawing, the present invention is further described and explained:

[0018] refer to figure 1 and figure 2 The coil 2 is added to the hollow part of the blade main body 1. The coil 2 is placed on both sides of the hollow web, symmetrically arranged, and directly in contact with the web. The circle formed by the coil has a smaller radius near the blade root Large, smaller near the blade tip, forming a shape that gradually decreases along the length of the blade. The coil pipe 2 is connected to the water tank 4 through the connecting pipe 3, and the water tank 4 is placed at the bottom inside the tower, and the connecting pipe is provided with a water pump and a valve, which are controlled by the drainage and injection control system. The water injection control system 5 is placed in the control box of the engine room, and is responsible for automatically adjusting the water in and out of the coil. The row water injection indicat...

Abstract

The invention provides a coiled tube type wind turbine generator blade and a regulating method thereof. The structure comprises a blade main body, a coiled tube, a connecting tube, a water tank, and a water discharging and filling control system and the like. With the structure, the total weight of the blade can be automatically regulated, the mass of the blade is increased through the filling of water to the coiled tube in the blade when the wind speed is too high, and the mass of the blade is reduced through the pumping of the water in the coiled tube to the water tank when the wind speed is lowered to a proper range. As a result, the rotating speed of the blade is nearly unchanged, thereby enlarging the applying range of the economic wind speed of the wind driven generator. Meanwhile, the rigidity of the blade can be improved, the capability of the blade for bearing external interference is lowered, and the rotating stability of the blade is improved.

Description

technical field [0001] The invention belongs to the technical field of wind power generating equipment and relates to a novel blade structure of a coil type wind power generator. Background technique [0002] Wind energy is a clean and renewable energy, and it is one of the new energies actively advocated by many countries, including my country. However, a big limitation of using wind energy is the narrow economic wind speed range. Generally speaking, the wind speed of 3-20m / s is the economic wind speed that the current wind turbine can adapt to. The start-up wind speed of the wind turbine is 3 to 4 m / s, and the cut-out wind speed (shutdown wind speed) is about 25 m / s. When the wind speed is lower than the starting wind speed, the wind turbine cannot generate electricity; when the wind speed exceeds the cut-out wind speed, the wind turbine must be shut down. Expanding the scope of use of wind speed has great practical significance in engineering practice. [0003] A wind...
