Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel technology, specifically to photovoltaic panel fixing structure and rooftop photovoltaic power generation system. Background Technology

[0002] In the current field of photovoltaic panel installation, the common method for installing photovoltaic panels on the surface of metal color steel tiles is as follows: the photovoltaic panels are clamped and fixed by the pressure blocks on the profiles, the profiles are connected to the clamping blocks by screws, and the clamping blocks are then installed on the surface of the metal color steel tiles by clamping or fixing with screws.

[0003] However, this fixed structure has the following drawbacks in practical applications: 1. When the clip is installed on the surface of the metal color steel tile, its anchoring effect is poor. When facing severe weather conditions such as strong winds, the weak anchoring force makes the clip easily detach from the metal color steel tile, which seriously threatens the installation stability and safety of the photovoltaic panel, may damage the photovoltaic panel, and thus affect the normal operation of the entire photovoltaic power generation system. 2. The pressure block and the profile are usually fixed by screws and slider nuts. During the installation process, the slider nut needs to be slid in from one end of the profile and then precisely aligned with the mounting hole on the pressure block. This operation is tedious and complicated, which consumes a lot of time, reduces installation efficiency, and increases installation difficulty. 3. In the fixing structure of photovoltaic panels, there are many types of profiles, and C-shaped steel is one of the most common. Since metal color steel tiles are generally in an inclined state, the side wall of the C-shaped steel will bear a large compressive force applied by the slider nut. In order to ensure the structural stability of the C-shaped steel under this stress, its thickness must meet specific requirements, which directly leads to an increase in the weight of the C-shaped steel, an increase in material consumption, and an increase in material costs.

A fourth through hole is provided on the first bent plate of the C-shaped steel component. Mounting holes are provided on the reinforcing plate, the insulation layer, and the rib strip.

[0035] Installation process of this utility model: Step 1: Prepare the C-shaped steel assembly. Stamp a first connecting plate, a first clamping plate, a second connecting plate, a third connecting plate, and a second clamping plate onto a metal substrate. Stamp a first clamping groove and a second clamping groove onto the second connecting plate. Then, bend both ends of the metal substrate to form a second bent plate, and insert the second clamping plate into the second clamping groove. Repeat this process by bending both ends of the metal substrate a second time to form a first bent plate, and inserting the first clamping plate into the first clamping groove, thus obtaining the C-shaped steel assembly.

[0036] Step 2: Install the C-shaped steel component; place the reinforcing plate on the protrusion of the corrugated steel sheet, and through the positioning of the fourth through hole on the C-shaped steel component, open the mounting holes on the corrugated steel sheet, the insulation layer and the rib strip, inject waterproof glue into the mounting holes, and pass the first fastener through the fourth through hole, the corrugated steel sheet and the insulation layer, and thread it on the mounting hole of the rib strip to complete the installation of the C-shaped steel component.

[0037] Step 3: Install the pressure block assembly; Insert the limiting block parallel to the groove between the two third bending plates, then press down the limiting block and rotate it 90 degrees. Then release the limiting block. Under the elastic action of the spring, the limiting part of the limiting block moves up and inserts into the groove between the two second bending plates. Then put the first washer on the limiting block, place the pressure block body on the first washer and fit it against the limiting block so that the first through hole and the threaded hole are aligned. Then install the fastening bolt in the third through hole and pre-tighten it in the threaded hole.

[0038] Step 4: Fix the photovoltaic panel body; place the photovoltaic panel body on the first pad so that the side of the photovoltaic panel body is in contact with the pressure block body, and then tighten the fastening bolts completely.
