Problems solved by technology

It makes it difficult for the system to track the sun accurately and reliably according to the design accuracy, especially for large-section concentrators
At present, the main means to solve this problem in China is to improve the machining accuracy of the transmission pair. However, this is undoubtedly at the cost of greatly increasing the manufacturing cost, and it cannot fundamentally solve the backlash difference caused by the wear and tear of the system. The problem of decreasing tracking accuracy

Abstract

A device capable of reducing or eliminating the backlash of a solar tracking transmission system relates to the improvement of a solar energy utilization device; it mainly involves using a reverse damping tracking system to solve the backlash of a mechanical transmission. The present invention provides a device which is simple in structure and easy to manufacture and can reduce or eliminate the hysteresis of the solar tracking transmission system. The invention includes an azimuth tracking system on the bottom surface of the box body. The end of the tracking system is a worm and a worm wheel, and the worm is driven by a motor. The key point of the structure is that the output shaft of the worm wheel is provided with a damping device.

Description

Technical field: [0001] The invention relates to the improvement of the solar energy utilization device; mainly relates to solving the return difference of the mechanical transmission of the tracking system by using reverse damping. Background technique: [0002] The existing tracking system of solar concentrator, due to reasons such as manufacturing precision and wear and tear, when being affected by external wind etc., when the passive wheel in the tracking system moves in the reverse direction, motion hysteresis (that is, the driven wheel breaks away from the same driving wheel) touch). It makes it difficult for the system to accurately and reliably track the sun according to the design accuracy, especially for large-section concentrators. At present, the main means to solve this problem in China is to improve the machining accuracy of the transmission pair. However, this is undoubtedly at the cost of greatly increasing the manufacturing cost, and it cannot fundamentally...
