Problems solved by technology

However, since the main body of the wind wheel is rotating, while the driving motor and the supporting structure are fixed, the sensor cables arranged on the rotating fan will interfere with the motion of the fixed structure, so it is difficult to measure the load on the rotating blade with this driving support method

Abstract

The invention provides a driving and supporting device for a vertical axis fan reduced scale model test. The driving and supporting device comprises a frame assembly, a power mechanism and a slip ring mechanism, and the power mechanism is in transmission connection with the slip ring mechanism through the frame assembly. According to the driving and supporting device for the vertical axis fan reduced scale model test, the fan body can be fixed to the bottom platform, and the fan body can be driven to stably run at the target rotating speed; meanwhile, the problem of motion interference when the sensor cable rotates is solved; in addition, a modular design concept is adopted, parts such as a driving motor, a transmission mechanism and a coupler can be flexibly replaced according to different test requirements, and certain universality is achieved.

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to a driving support device for scaled-scale model tests of vertical-axis wind turbines. Background technique [0002] In recent years, the excessive consumption of traditional fossil energy such as oil and coal has caused great damage to the ecological environment. At present, the world has reached a general consensus on vigorously developing green and clean energy. As a clean, pollution-free and renewable green new energy, wind power has been recognized by more and more people. Wind turbines are currently the most widely used wind energy development and utilization equipment. According to the spatial position relationship between the rotation axis of the wind rotor and the direction of incoming flow or the ground, fans can be divided into horizontal axis fans and vertical axis fans. Due to relatively high conversion efficiency of wind power and relatively low cost, horizonta...
