Self-locking deceleration support bearing for photovoltaic support

Abstract

The invention provides a self-locking deceleration support bearing for a photovoltaic support. The self-locking and deceleration characteristics are realized; the self-locking characteristic is that the large-scale single-shaft automatic tracking photovoltaic support is integrally locked in case of strong wind. The resonance phenomenon with large destructive power is eliminated; the photovoltaic support is protected; due to the deceleration characteristic, the photovoltaic support can be supported and rotated without a long and heavy rotating beam; accurate coaxial installation is not needed;the construction is easy; the foundation settlement photovoltaic support can still operate, the operation reliability is improved, a small speed reducer and a motor can be used for driving the large single-shaft automatic tracking photovoltaic support according to the deceleration characteristic, the manufacturing cost of the photovoltaic support and the power consumption of the motor are reduced,and the bearing has the advantages of being small in size, light in weight and low in manufacturing cost.

Description

technical field [0001] The present invention is a support and rotating bearing for a large-scale single-axis automatic tracking photovoltaic bracket, which belongs to the application field of photovoltaic power generation and solar thermal power generation that automatically tracks the sun, and specifically relates to a large-scale single-axis automatic tracking photovoltaic bracket and support that need support and rotation and in devices that rotate and automatically track reflectors in solar thermal power plants. Background technique [0002] At present, the general single large-scale single-axis automatic tracking photovoltaic support uses a long and thick rotating beam to load many photovoltaic modules. The long and thick rotating beam passes through several bearings, and several bearings are installed on several columns standing on the ground. Above, the rotating beam is connected to the reducer and the motor, and the reducer and the motor drive the rotating beam to ro...

Problems solved by technology

When encountering strong winds, many photovoltaic modules have great wind resistance, which will generate a large torque on the rotating beam, causing the rotating beam to twist with the wind and generate resonance, which will damage the reducer and the entire bracket. The current solution to this problem is to install on the rotating beam Damping rod, the resistance of the damping rod is very large and cannot be added too much. Generally, it is installed at both ends of the rotating beam. Because the rotating beam of the large single-axis automatic tracking bracket is very long, the installation of the damping rod cannot eliminate the resonance damage caused by strong winds. The phenomenon of the reducer and
