Description

Profile pressings and photovoltaic systems

technical field

The utility model mainly relates to installation accessories of photovoltaic modules, in particular to a profile pressing piece for combining and fixing profiles and a photovoltaic system installed with the profile pressing piece.

Background technique

A solar photovoltaic module consists of a solar cell and a profile that surrounds the solar cell. The role of the profile is to increase the mechanical strength of the solar cell and to seal the edge of the solar cell. In the actual installation process, it is necessary to further realize the fixing between the photovoltaic module with the profile and the bracket through the profile pressing piece, and splice the adjacent photovoltaic modules.

The current method of installing photovoltaic modules on the bracket is to use profile pressings and bolts. The specific installation steps are that the operator first assembles the adjacent photovoltaic modules placed on the bracket through the profile pressing parts, and then uses bolts to pass through the profile pressing parts between adjacent photovoltaic modules and tighten them. Since the photovoltaic module has been assembled, the operator can only tighten the bolts on the side (called the fixed side) where the profile pressure piece is installed across the photovoltaic module on the side of the photovoltaic module that is not installed with the profile pressure piece (called the free side). However, as the demand for photovoltaic modules continues to increase in the market, large-size photovoltaic modules are gradually becoming popular, and the width of some photovoltaic modules can even reach about 1.3m. As a result, when the operator wants to tighten the bolts far away from the fixed side, the arm span is not enough, it is difficult to tighten, and even some irregular operations of kneeling and pressing the photovoltaic modules occur, which increases the risk of component cracks.

Utility model content

The technical problem to be solved by the utility model is to provide a profile pressing piece that can continue to install photovoltaic modules after the bolts are tightened.

In order to solve the above-mentioned technical problems, the utility model provides a profile pressing part for combining and fixing profiles.

Specifically, the first crimping member 100 is fixed to the bracket 30 by bolts 50 and lock nuts 40, and the profile 21 is fixed in the space formed by the first pressing piece 110, the first side plate 120, the first bearing plate 131 and the second bearing plate 132 of the first crimping member 100 (because the profile 21 is blocked, the first bearing plate 131 and the second bearing plate 132 are not shown in FIG. 6 , and can be combined with reference to FIG. 1).

Fig. 7 is a three-dimensional schematic diagram of the installation process of a second crimping member according to an embodiment of the present invention. 3, 6-7, it can be understood that in a profile pressing member 10 provided by the present invention, in order to make the first pressing member 100 and the second pressing member 200 fixed together, the photovoltaic module 20 fixed at both ends is kept at the same height relative to the bracket 30, the height of the first fastening part 140 relative to the first bearing plate 131 and the second bearing plate 132 is different from the height of the second fastening part 240 relative to the third bearing plate 231 and the fourth bearing plate 232.

Further, it is believed that the above content has clearly explained the reason why the first crimping member 100 is installed at the end of the photovoltaic system in FIG. 6 . However, it should be emphasized that in some other embodiments of the present invention, the height of the first fastening portion 140 relative to the first loading plate 131 and the second loading plate 132 may be greater than the height of the second fastening portion 240 relative to the third loading plate 231 and the fourth loading plate 232, that is, when the first crimping member 100 and the second crimping member 200 are fixed as one, the lower surface of the first fastening portion 140 is attached to the upper surface of the second fastening portion. It can be understood that, in this embodiment, the second crimping part 200 is installed at the end of the photovoltaic system, and does not need to cooperate with the first crimping part 100, and in the installation process of the profile pressing part 10, a second crimping part 200 must be installed before installing the first crimping part 100.
