Description

Locking mechanism and tracking bracket Technical Field The invention relates to the technical field of tracking brackets, in particular to a locking mechanism and a tracking bracket. Background The photovoltaic tracking bracket is used as a structural device specially designed for a photovoltaic power generation system, and has the main functions of supporting and fixing a photovoltaic module (such as a solar panel), and simultaneously carrying out automatic or manual adjustment according to the movement track of the sun so as to maximize the angle and time of the photovoltaic module for receiving solar radiation, thereby improving the power generation efficiency. One of the important factors that the structure of the tracking bracket is destroyed is a heavy wind load, and the existing tracking bracket has at least one of the following problems when dealing with heavy wind: 1. Only a single worm and gear reducer arranged in the middle of a single row is used as a self-locking point, and a torque tube far away from the middle position is easy to deform and damage under the working condition of strong wind; 2. Although some manufacturers set corresponding strong wind protection strategies, the photovoltaic module is stopped at a small angle (namely, the photovoltaic module is positioned at a position close to the flat position) to reduce wind load or at a large angle (namely, the limit angle of rotation of the tracking bracket) to provide more locking point protection, the corresponding time for rotating to the small angle or the large angle is long because the time for the strong wind to come in cannot be accurately judged, and the bracket structure can be damaged in the process of rotating to the small angle or the large angle; 3. In the prior art, the scheme of using multi-point electric drive to drive the tracking bracket to rotate is provided, the locking is performed at any angle through the unidirectional self-locking function of a plurality of synchronous rotating worm and gear speed reducers, but because a plurality of drives are adopted, and the synchronous rotation is realized by the mutual communication among the plurality of drives, the cost is higher, and the multi-point electric drive tracking bracket is not suitable for large-scale popularization and use.
