Abstract

The invention relates to the technical field of wind power generation, and discloses a wind driven generator blade connecting structure free of screw installation, including blades. During installation, the blades are firstly inserted into inserting rods; four guide grooves are also connected with four guide rods in an inserting manner; then a cavity is inflated through an air inlet valve; gas isfilled to push a valve plate to move upwards; the valve plate moves upwards to drive a vertical rod to move upwards and compress a spring; the vertical rod moves upwards to drive a limiting block to move upwards; the limiting block moves upwards to push a first hinge block and a second hinge block to rotate; the clamping block is clamped at the top; securing the position of a blade, during disassembly, gas is discharged through the gas outlet valve; the air exhaust spring loses the support of air pressure and returns to the original position under the action of self elasticity, the spring returns to the original position to drive the vertical rod to descend, the vertical rod descends to drive the limiting block to descend, at the moment, the first hinge block and the second hinge block canfreely move without being blocked by the limiting block, and the blades can also be easily disassembled.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a screw-free installation of a wind power generator blade connection structure. Background technique [0002] Wind turbines can convert wind energy into electrical energy, which is an environmentally friendly, non-polluting, and renewable new energy technology. Wind turbines can generally be divided into four types: asynchronous type, synchronous type, horizontal axis, and vertical axis according to the structure type. The most widely used is the horizontal axis wind turbine, which has contributed a huge amount of electricity to the production and construction of our country. However, in actual use, we found that the traditional wind turbine still has certain shortcomings, such as: [0003] 1. Traditional wind turbine blades are generally connected by screws, but the operation of screw connection is cumbersome, and there is a certain danger when working at heights; ...
