Description

Solar panel roof waterproof structure

The present invention is related to the scaffold structure, in particular to a waterproof structure for the roof of a solar power generation panel.

By the way, solar panels can generate electricity by absorbing solar energy, so they must be installed outdoors to receive the sun, but in rainy days, they will inevitably be exposed to rain. As rainwater falls from the sky, it entrains and adheres to impurities in the air, making it slightly acidic. Solar panels are metal products. When rainwater is encountered, the surface protection layer will be corroded, causing adjacent solar panels. A gap is formed between them. When rainwater enters the gap, it will short-circuit the solar panel and cause leakage, which will lead to damage and failure.

In order to solve the aforementioned problems, the applicant in this case previously filed a patent application for a solar panel waterproof structure, which was registered as Announcement No. M595363. The patented structure includes two rows of fixed racks arranged at intervals, a number of solar panels are arranged between the fixed racks, a waterproof insulating rubber strip is arranged at the junction of two adjacent solar panels, and a waterproof insulating rubber strip is coated on top of the waterproof insulating rubber strip. The waterproof coating is then covered with an anti-ultraviolet layer cover on top of the waterproof coating to avoid the aging of the waterproof insulating tape and the waterproof coating caused by direct sunlight and the occurrence of cracks and water leakage.

However, after using the above-mentioned patented structure for a period of time, the applicant found that the anti-ultraviolet layer cover simply covers the surface adjacent to the solar panel, and there is still a gap between it and the fixing frame, so rain water can still penetrate through this gap and affect the solar panel. Normal operation. In view of this, how to improve the above-mentioned problem is the primary problem to be solved by the present invention.

The main purpose of the present invention is to provide a solar panel roof waterproof structure, the two ends of the anti-ultraviolet adhesive tape are bent downward to extend between the fixing frame and the solar panel, so that the fixing frame is tightly connected with the anti-ultraviolet adhesive tape to eliminate the gap. Reduce the chance of rainwater intrusion.

In order to achieve the foregoing objective, the present invention provides a solar panel roof waterproof structure, which includes two fixed frames arranged side by side at intervals, a plurality of solar panels arranged in a straight line are fixed between the two fixed frames, and each solar panel is divided into two Each abutting side abuts against the two fixing frames, wherein a waterproof and insulating first rubber strip is arranged between two adjacent solar panels, which extends to both ends of the abutting sides of the two solar panels, the first The top surface of the rubber strip is lower than the top surface of the solar panel and a groove-shaped space is formed above the first rubber strip, and the groove-shaped space is filled with a waterproof glue layer; the adjacent place of two adjacent solar panels is provided with a groove The anti-ultraviolet adhesive tape covers the groove-shaped space and completely shields the waterproof adhesive layer. The anti-ultraviolet adhesive tape has two ends which are respectively pressed by two fixing frames, and each end protrudes a downward bending section. The folding section extends between the abutting side of the fixing frame and the solar panel and is in close contact with the two.

The length of the bending section is greater than the thickness of the waterproof adhesive layer. Preferably, the bent section extends downwardly beyond the first rubber strip.

In one embodiment, each fixing frame includes a bottom frame and a fixing frame locked on the bottom frame. The bottom frame has a top plate.
