Abstract

The invention relates to a reducing wind power blade endoscopic detection robot. The reducing wind power blade endoscopic detection robot comprises a traveling mechanism, a reducing mechanism and a supporting mechanism; the reducing mechanism is mounted at the upper part of the traveling mechanism; the supporting mechanism is mounted at the upper part of the reducing mechanism; the traveling mechanism is formed by four traveling units with the same structure; each traveling unit is controlled by one traveling stepping motor; two traveling units form one group, and two groups of traveling unitsare placed according to front and rear positions; the reducing mechanism consists of two parts with the same structure; each part comprises a screw motor, a screw, screw nuts, guide shafts, sliding blocks, springs and a shear type structure, two screw nuts are symmetrically mounted on the screw, two screw nuts are arranged in a positive and negative screw thread mode, and the screw nuts pass through the guide shafts; the sliding blocks are mounted on the corresponding screws inside the screw nuts; and the springs are mounted between the sliding blocks and the screw nuts adjacent thereto. Therobot can be suitable to detect a large reducing and variable curvature pipeline.

Description

technical field [0001] The present invention relates to the field of robotics. Especially the wind turbine blade endoscopic detection robot involving large variable diameter. Background technique [0002] With the proposal of the national sustainable development strategy, wind energy has become an indispensable part of my country's development of new energy sources. Wind turbine blades are one of the key components for wind turbines to receive wind energy, accounting for about 20% of the total cost. With the increasing number of wind power generating units, people have put forward higher requirements for the detection of wind power blades. According to the accident analysis of wind turbines in wind farms, there are many problems of blade bonding and cracking, so all bonding areas of blades are damaged. It is a key area that affects the safety of the blade structure. At present, in China, professional equipment and well-trained technicians are required for the inspection of...
