Centrifugal self-locking damping mechanism and photovoltaic device

Abstract

The invention provides a centrifugal self-locking damping mechanism and a photovoltaic device, and relates to the photovoltaic field. The centrifugal self-locking damping mechanism comprises a locking body and a cylindrical rotating body, the middle part of the locking body is provided with a cylindrical slot matched with the rotating body, one end of the rotating body is inserted into the cylindrical slot and is rotatably connected with the cylindrical slot, a lock pin part capable of sliding out outwards is embedded in the rotating body, at least one group of clamping grooves matched with the lock pin part are formed in the upper part of the cylindrical slot, the front end part of the lock pin part slides out and is inserted into the clamping grooves to brake the rotating body, and when sudden change external acting force is applied to the photovoltaic panel, the photovoltaic panel pulls the rotating body to rotate through the steel wire rope, the lock pin part embedded in the rotating body slides outwards under the action of centrifugal force until the front end part of the lock pin part slides out and is inserted into the clamping groove, and then the rotating body is braked, so the damping effect is achieved, the application range is wide, and the follow-up maintenance cost is low.

Description

technical field [0001] The invention relates to the photovoltaic field, in particular to a centrifugal self-locking damping mechanism and a photovoltaic device. Background technique [0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect of the semiconductor interface. Photovoltaic tracking brackets are an important component of photovoltaic power generation. At present, on a global scale, photovoltaic tracking brackets are used in Gobi, Deserts, tidal flats, grasslands, wastelands and other wild environments away from urban crowds. The climate and environment of the site where it is located is often complex and changeable, and sudden extreme weather may also occur in individual areas, such as strong winds, heavy snow, floods, earthquakes, etc. [0003] In order to ensure a 25-year service life of the photovoltaic tracking bracket in a complex and changeable field environment, the sta...

AI Technical Summary

Problems solved by technology

[0005] a. The service life of the damper is difficult to match the 25-year service life of the tracking bracket, mainly due to the oil leakage of the damper and the corrosion of the weld seam of the damper. It is difficult to achieve 25 years of maintenance-free, and it needs to be replaced after damage, and the later operation and maintenance costs higher;

[0006] b. The load that the damper can withstand is a fixed value and is not adjustable. It is impossible to use one damper to meet most of the use requirements. Every project needs to be re-selected and calculated. Not only the workload is heavy, but also Difficulty coping effectively with changing environments
