Strength detection device for wind wheel blade of fan generator set

Abstract

The invention discloses a strength detection device for a wind wheel blade of a fan generator set. The strength detection device comprises a bottom plate, a box body, a hydraulic cylinder and a forward and reverse rotation motor, a notch is formed in the inner side of the bottom plate, a fixing base is fixedly connected to the upper end of the bottom plate, a fixing groove is formed in the fixing base, a blade is inserted into the fixing groove, a fixing rod is connected in the fixing base through threads, the lower end of the fixing rod is in close contact with the surface of the blade, the box body is fixedly connected to the upper end of the bottom plate, the inner side of the box body is fixedly connected with the fixing base, and a first switch and a second switch are fixedly installed at the right end of the box body; the first switch and the hydraulic cylinder are connected with an external power source in series through wires, and the second switch and the forward and reverse rotation motor are connected with the external power source in series through wires. According to the strength detection device for the wind wheel blade of the fan generator set, the strength detection device has the characteristics of convenience in transferring and clamping, capability of realizing multi-point detection and safety protection.

Description

technical field [0001] The invention belongs to the technical field of fan generator sets, in particular to a strength detection device for wind rotor blades of a fan generator set. Background technique [0002] The wind power generation power supply is composed of wind turbines, towers supporting generators, battery charge controllers, inverters, unloaders, grid-connected controllers, battery packs, etc.; wind turbines include wind rotors, generators; wind rotors It consists of blades, hubs, reinforcements, etc.; it has the functions of blades being rotated by wind to generate electricity, and the head of the generator rotating. [0003] The core component of the wind turbine generator set is the wind rotor blade. The performance of the wind rotor blade is very critical. During the inspection process of the wind rotor blade, the strength of the blade needs to be tested. However, the existing strength detection device is inconvenient to transfer and clamp the blade, resulti...

AI Technical Summary

Problems solved by technology

However, the existing strength detection device is inconvenient to transfer and clamp the blade, resulting in inconvenient detection, and it is inconvenient to adjust the position during detection, which is not conducive to selecting different detection points for detection, and lacks safety protection during detection
