At present, the sun is a clean energy source with good application prospects. It is of great significance to use solar energy to generate electricity as a supplement to thermal power or hydropower in areas with abundant sunshine. In order to obtain the ideal sunlight effect, the solar panels must be installed at an inclination angle of 8-12 degrees, which requires a foundation for the installation of solar panels. The traditional method is to cast cement piers on flat ground or flat roofs, and cast cement on flat ground Although the pier operation is not too difficult, there are also problems such as long installation period, high cost, and difficult removal. Casting cement pier on the flat roof will destroy the overall structure of the roof, increase the load-bearing pressure, and the operation is difficult. The construction period Therefore, it is imperative to design a fixed bracket suitable for installation on flat surfaces, especially on flat roofs. the

The front fixed rod 102 and the rear fixed rod 104 are channel steel structures, and anti-slip rubber pads 5 are installed in the grooves on the side where they are in contact with the roof. the

The connecting screw 4 simultaneously connects the briquetting block positioning connector 2 , the front fixing rod 102 and the rear fixing rod 104 of the adjacent bracket 1 inserted into the front fixing rod 102 into one body. the

The pressing block positioning connector 2 is composed of at least one groove opening downward and two grooves opening upward, and the two grooves opening upward are symmetrically distributed on both sides of the groove opening downward. the

The included angle between the inclined rod and the horizontal plane is 8-12 degrees. the

The beneficial effects of the utility model:

The utility model has the advantages of simple structure, fast and convenient installation, and the support can be firmly positioned on the flat roof by using the counterweight press block, the anti-slip rubber pad and the gravity of the solar photovoltaic module itself, and all the supports and the photovoltaic module panel form an integrally connected structure. The structure has good stability, and the effect of wind force on the photovoltaic module can be eliminated through the windshield on the top surface, so as to increase the stability.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further. the

As shown in Figure 1-3. the

A solar module fixing bracket for a flat roof, which consists of two brackets 1 (Fig. 1) with the same structure, a pressure block positioning connector 2 (Fig. 3) and a top windshield 3 (Fig. 1). The bracket 1 is composed of a slanting bar 101, a front fixing bar 102, a side bar 103 and a rear fixing bar 104. The length of the slanting bar 101 matches the width of the side of the solar photovoltaic module 7, and the solar photovoltaic module 7 can pass the fastener Or the connecting bolts are connected to the slanting rod 101, the angle of the slanting rod 101 should be controlled between 8-12 degrees, preferably about 10 degrees, and the side rod 103 is connected to the top windshield 3 through a threaded connector; Described front fixed rod 102 and rear fixed rod 104 are equipped with the connecting screw 4 that links to each other with the corresponding rear fixed rod 104 on the adjacent fixed bracket and front fixed rod 102, front fixed rod 102 and rear fixed rod 104 can adopt Channel steel structure, anti-slip rubber pads 5 are installed in the grooves on the side where they are in contact with the roof; the pressure block positioning connector 2 is composed of an upward groove and a downward groove, The groove is used to place the counterweight pressing block 6, and the downward opening groove is connected with the front fixing rod 102 in the bracket 1. According to the position of the bracket 1, the structural form of the pressing block positioning connector 2 is also different. Since the pressure block positioning connectors 2 on both sides of the entire power generation unit do not need to play the role of connecting adjacent supports, the structure can adopt a structure with one downward opening groove and two upward opening grooves, as shown in Figure 3 , the briquetting block positioning connector 2 used in the middle position needs to connect adjacent brackets, therefore, the briquetting block positioning connector 2 should adopt the structure of two downward opening grooves and three upward opening grooves, each Prefabricated cement blocks, bricks and stones are placed in each upward opening groove. the

During installation, in order to link the briquetting block positioning connector 2 to the bracket, the connecting screw 4 can simultaneously position the briquetting block locating connector 2, the front fixing rod 102 and the rear fixing rod of the adjacent bracket 1 inserted in the front fixing rod 102 104 are connected as a whole, square or elongated nut 8 can be placed in the groove of front fixed rod 102 or rear fixed rod 104 so as to match with connecting screw 4. the

Fig. 2 is a schematic structural view of a group of solar power generation units using the fixed bracket of the present invention. the

The parts not involved in the utility model are all the same as the prior art or can be realized by adopting the prior art. the
