Automatic protection device of photovoltaic solar device

Abstract

The invention discloses an automatic protection device of a photovoltaic solar cell panel. The automatic protection device comprises a solar cell panel and a bracket thereof, a solar cell panel protection curtain plate and a driving device thereof, and slide grooves formed in the two sides of the bracket of the solar cell panel, wherein a curtain plate supporting frame is arranged on the bracket of the solar cell panel; a hairbrush is arranged at the front end of the curtain plate; the bracket of the solar cell panel is arranged on a bracket capable of moving up and down, forwards and backwards; and the bracket of the solar cell panel can be used for adjusting the levelness of the bracket of the solar cell panel through an electric screw rod device and a slide way mechanism at the front part. A sensor provided by the invention can be used for detecting a signal of bad weather; and the curtain plate covers the solar cell panel so that the protection aim is realized. Particularly, an air speed signal is detected through an air speed sensor and a solar device is prone to be a leveled state by a control device through the electric screw rod device, so that damages of air pressure are reduced.

Description

technical field [0001] The invention relates to an automatic protection device of a photovoltaic solar energy device. Background technique: [0002] With the vigorous development of my country's photovoltaic power generation industry, the power generation efficiency and service life of photovoltaic power generation systems have also received increasing attention. [0003] Photovoltaic solar panels are an important part of the photovoltaic power generation system. They are used to receive solar energy and convert them into electric energy.

AI Technical Summary

Problems solved by technology

[0003] Photovoltaic solar panels are an important part of the photovoltaic power generation system. They are used to receive solar energy and convert it into electrical energy. Because they are exposed to the outside and the surrounding environment is complex, especially there are many houses and trees around distributed photovoltaics. Although there are tempered glass on the surface of the panels, they are protected The ability is average. In strong convective weather, branches broken by strong winds, bricks and tiles blown down, hail and snow in winter are easy to cause damage to the fragile crystalline silicon wafers under the glass of the panel, reducing its power generation efficiency and shortening its service life. Solar panels are generally installed on the top or high places of buildings. Traditional manual protection methods are costly and pose personal safety risks.

[0004] Chinese patent authorization announcement number CN201248602 discloses a solar water heater sun-shading and rain-proof roller blind device. The device includes an electric winding mechanism, end plates at both ends of the electric winding The guide rails at both ends of the sheet, the present invention lacks specific technical details about sunshade and rain protection, and the technical effect cannot be realized by the narration of the invention

However, the description of the present invention lacks a corresponding sensing device, and the remote control operation needs to be carried out manually, and automatic operation cannot be realized, which is time-consuming and laborious, and the response is not timely enough, and the safety of the solar battery cannot be guaranteed in case of an emergency.

[0006] In strong windy weather conditions, the horizontal angle between the existing solar panel and the ground is relatively large, and the solar panel support is subjected to a large wind pressure, which is likely to cause the solar panel support to be reversed by the wind and deformed. Waiting for failure

[0007] Under the actual conditions of serious environmental pollution, the existing automatic protection devices for photovoltaic solar devices lack the cleaning function for solar panels in addition to the necessary protection functions.
