Photovoltaic panel hail prevention device capable of reducing extension of shielding layer for photovoltaic power station

Abstract

The invention discloses a photovoltaic power station photovoltaic panel hail prevention device capable of reducing shielding layer extension in the technical field of photovoltaic equipment; the device comprises a photovoltaic panel and an installation box, a winding roller is rotatingly installed between the inner walls of the front and rear sides of the installation box, the outer wall of the winding roller is sleeved with a clockwork spring, and the outer wall of the clockwork spring is sleeved with a circular ring. The outer wall of the circular ring is fixedly connected with a shielding device, the right end of the shielding device extends to the outer wall of the right side of the mounting box and is fixedly connected with a pull plate, so that the hail only makes contact with the upper shielding layer through the shielding device with the upper shielding layer and the lower shielding layer arranged in a double-layer spaced mode; and when the force is released by the upper shielding layer, the upper shielding layer and the lower shielding layer are isolated by a space therebetween, so that the contact probability of the upper shielding layer and the lower shielding layer is reduced when the upper shielding layer is sunken, the hail collision probability of the lower shielding layer is reduced, the extension sunken probability of the lower shielding layer due to stress is reduced; therefore, the impact force of hail is prevented from the photovoltaic panel.

Description

Technical field[0001]The present invention relates to the field of photovoltaic equipment, in particular, a photovoltaic power plant photovoltaic plate to reduce the occlusion layer.Background technique[0002]In the process of using the photovoltaic plate, it is generally damaged to the photovoltaic plate to cope with the extreme weather, and the hail can not be installed on the photovoltaic plate, and the hail will not be smashed into the photovoltaic plate by covering the photovoltaic plate. Reduce the space occupied by the anti-hail unit, and the obstruction of the cover is generally made of a rewardable cloth, but in the process of blocking the hail, it will have a certain impact force due to the drop of hail, when hail and When the polyester Oxford cloth is in contact, the impact of the polyester Oxford cloth will extends the recesses, and the cloth is a region where the surface is close to the surface of the photovoltaic plate, causing the cloth recessed area to be in contact w...

Problems solved by technology

[0002] During the use of photovoltaic panels, in order to deal with the damage to photovoltaic panels caused by extreme weather, anti-hail devices are generally installed on photovoltaic panels, and by covering the top of photovoltaic panels, hail will not hit photovoltaic panels. To reduce the space occupied by the anti-hail device, the covering layer is generally made of rollable cloth. However, in the process of blocking hail, the cloth will have a certain impact force when the hail falls. When the hail and When the polyester oxford cloth is in contact, the polyester oxford cloth will be stretched and dented by the impact of the falling hail, and the cloth is covered in the area near the surface of the photovoltaic panel, which makes the dented area of ​​the cloth easy to contact with the surface of the photovoltaic panel, resulting in the process of hail falling Part of the hail will also affect the surface of the photovoltaic panel, resulting in a decline in the protection effect of the anti-hail device. Therefore, we propose a photovoltaic panel anti-hail device for photovoltaic power stations that can reduce the extension of the shielding layer.
