[0002] The main function of photovoltaic panels is to convert solar energy into electrical energy. No other energy needs to be used in the conversion process. Solar energy can be converted into electrical energy. It is of great significance in modern society. It can provide clean energy and help improve environmental pollution problems.

[0003] With the increasing use of solar energy in buildings, in order to reduce material and installation costs, people combine solar photovoltaic modules with building roofs to form solar photovoltaic building integration, that is, after multiple solar photovoltaic modules are spliced ​​together, they can be used as roofs while converting solar energy into electricity or other energy. In actual installation, a frame bracket is generally erected on the roof of the building first, and then the solar photovoltaic modules with outer frames are fixed to the bracket for use.

[0004] In the splicing of solar photovoltaic modules, manual operation is generally used. In view of this, the gaps required to be reserved between adjacent solar photovoltaic modules are usually located and reserved by construction workers by visual inspection. However, this method has certain limitations. In the actual construction process, in order to ensure that the width difference of each gap is maintained within a small range, construction workers need to spend a long time to visually inspect the width of the gap when installing each solar photovoltaic module, which makes the overall construction efficiency at a low level.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the base is placed on the roof and fixed by bolts, and then the fixing bolts are rotated upward to separate them from the positioning plate. At this time, the positioning plate will be moved out of the base under the action of the driving spring, and then the positioning plate is rotated to move it to a position perpendicular to the base.

In this process, when the fixing pin is installed, the fixing pin is completely retracted into the inside of the beam, and the through hole faces the fixing sleeve. Then the push-pull rod is pushed to drive the movable ring away from the adsorption range of the annular magnet. At this time, the connecting spring will return to its original position, so that the push-pull rod passes through the fixing pin, thereby preventing the fixing pin from loosening and improving the positioning rate of the beam.

When the photovoltaic panel moves to the positioning slot facing the storage slot, the positioning block will hit the bottom of the storage slot under the action of the lifting spring, thereby making a sound, thereby reminding the operator that the positioning is successful and improving the positioning rate of the photovoltaic panel.
