Roof distribution type power station photovoltaic combiner box protection cover

Abstract

The invention discloses a roof distribution type power station photovoltaic combiner box protection cover comprising a photovoltaic combiner box. A support pedestal is arranged at the bottom of the photovoltaic combiner box; and fixation devices are arranged at the left side and the right side of the support pedestal. A reinforced base plate is arranged at the bottom of a screw rod. A protection cover is arranged at the top end of the photovoltaic combiner box; standing posts are arranged at the left side and the right side of the protection cover; fixed rings are arranged on the outer walls of the standing posts; and a buffer device is arranged at the top end of the protection cover. According to the protection cover, when uncertain impact forces are exerted externally, a buffering seat presses down to press a first spring and a second spring to buffer external impact forces based on sliding connection of the buffer seat and a support bench, so that damages of equipment in the photovoltaic combiner box by the external impact forces can be avoided. Because of threaded connection of the screw rod and the reinforced plate, the reinforced base plate moves downwardly by twisting the screw rod, thereby enhancing stability of the support pedestal.

Description

technical field [0001] The invention relates to the technical field of combiner boxes, in particular to a protective cover for a photovoltaic combiner box of a roof distributed power station. Background technique [0002] The installation of combiner boxes in rooftop photovoltaic power stations is often done in a flat way. Due to the long-term exposure to sunshine and wind and rain, anti-aging and waterproofing are of great significance to the life and safety of electrical equipment in the box. It is difficult to ensure the protection of photovoltaic combiner boxes by themselves. The safety of internal equipment is difficult to ensure sufficient anti-aging and waterproof requirements. Uncertain external impact often damages internal equipment. At the same time, when the equipment is squared, it is very unstable and often moves, which affects photovoltaic confluence. normal use of the box. Contents of the invention [0003] The purpose of the present invention is to provid...
