Description

A new type of photovoltaic support fixture

technical field

The utility model relates to the technical field of solar photovoltaic brackets, in particular to a photovoltaic bracket fixture used for fixed connection with a sandwich color steel plate on the roof when a solar photovoltaic power station is installed on the roof.

Background technique

The Ministry of Industry and Information Technology formulated the "Twelfth Five-Year Development Plan for Solar Photovoltaic Industry", which clearly pointed out that the installed capacity of solar photovoltaics will reach 40GW during the Twelfth Five-Year Plan, especially the "National Development and Reform Commission The Notice on Using Price Leverage to Promote the Healthy Development of the Photovoltaic Industry has intensified the speed of installing solar photovoltaic power stations on industrial and civil roofs.

Most of the existing industrial roofs are sandwich color steel plate roofs. Photovoltaic power stations are built on sandwich color steel plate roofs. The fixing bracket purlins are fixed on the photovoltaic support fixtures through the connection between the photovoltaic support fixture and the sandwich color steel plate, and the photovoltaic module panels are fixed on the support purlins. superior. In this way, the main components of the photovoltaic power station have been installed on the sandwich color steel plate roof. It can be seen from the above that in the photovoltaic power station on the roof of the sandwich color steel plate, the entire power station is fixedly connected with the sandwich color steel plate through the photovoltaic support fixture, but the roof leakage problem caused by the connection and fixation between the photovoltaic support fixture and the sandwich color steel plate is a problem in the industry. There has been no effective solution.

In the prior art, there are two common ways to connect the photovoltaic support fixture and the sandwich color steel plate. One is as shown in Figure 1. The photovoltaic support fixture is fixed on the factory building by self-tapping nails piercing the sandwich plate from the peak of the sandwich color steel plate. The other is shown in Figure 2. The photovoltaic support fixture is fixed on both sides of the sandwich panel by two self-tapping screws piercing through the sandwich panel from both sides of the sandwich panel. But no matter which connection method, the waterproof treatment of the sandwich color steel plate is realized by installing rubber pads on the above self-tapping screws.

This kind of roof waterproofing with rubber mats alone is not enough. If the rubber pad is aging and the self-tapping screw shakes back and forth under the wind load, the rainwater can directly enter the connection hole between the self-tapping screw and the sandwich color steel plate, and enter the color steel plate, causing water to enter the color steel plate.

Detailed ways

The utility model is further described below in conjunction with the specific embodiment of the utility model:

As shown in FIGS. 3 to 9 , the photovoltaic support fixture of the preferred embodiment of the present invention includes an upper fixture 1 , a lower fixture 2 and two covers 3 .

The lower fixture 1 includes a top plate 11 for supporting the bracket purlin 9 and also includes two side plates 12 . The two side plates 12 of the upper fixture 1 together with the top plate 1 constitute a cover over the lower fixture 2 , and the lower fixture 2 is inside the upper fixture 1 .

The lower fixture 2 is L-shaped, and the L-shaped horizontal plate is provided with a mounting hole 21, and the self-tapping screw 4 passes through the mounting hole 21 and the crest of the sandwich color steel plate and is fixed on the steel structure purlin 5 of the factory building. As shown in Figure 3, the L-shaped vertical board is located on the right side of its horizontal board. The vertical plate and the side plate on the right side of the upper fixture 1 are fixed by bolts 6, and there is also a rubber pad 7 for waterproofing between them. The height of the side plates 12 of the upper fixture 1 is such that after the lower fixture 2 is fixed on the top of the crest of the sandwich color steel plate, the lower edges of the side plates 12 are just close to the troughs on both sides of the crest of the sandwich color steel plate. A nut 8 for locking the bolt 6 is also welded on the vertical plate of the lower clamp 2 on the side facing away from the rubber pad 7 . In this way, when the bolt 6 is tightened to fix the upper and lower clamps, the operation can be more convenient.
