Background technique

Commercial roofs, especially large commercial roofs, are especially suitable for the construction of solar power plant phalanxes due to their large area and their location in commercial centers with high electricity demand. However, since commercial roofs are mostly located in the city's office and commercial centers, the environment has higher requirements for construction.

At present, in the construction projects of commercial rooftop solar power plants, it is necessary to build cement piers on the roof in the early stage to fix the solar cell modules. This construction method will destroy the original structure of the roof, which is not conducive to the later restoration; after the cement pier is built, all parts will be installed on the roof. The installation and construction process is due to the harsh working environment on the roof and it is easy to cause noise to the daily work and life of users. and dust pollution.

The traditional support system has disadvantages such as high cost, large workload during the construction process of the support system square array, easy to affect users, and heavy ground restoration work in the later period of photovoltaic power station use. Therefore, it is urgent to design a solar array suitable for large-scale commercial rooftops. bracket system.

Detailed ways

In order to make the technical problems, technical solutions and beneficial effects solved by the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in FIG. 2 , a solar cell support includes a support 1 and a base 2 . A solar cell module 3 is installed on the support member 1, and a weight 5 is installed on the base 2. In this embodiment, the weight 5 is a brick. The support 1 is then fixed on the base 2 .

In Fig. 2, there are two bases 2, and the two bases 2 are placed opposite to each other, and the distance between them depends on the horizontal length of the support 1; in addition, the base 2 can also be a whole, that is, the width of the base 2 equal to or greater than the horizontal length of the support 1, so that the support 1 can be directly installed on such a base without assembling it. This embodiment adopts a combination method, as shown in FIG. 2 .

Base 2 is directly placed on the roof, and is pushed down with heavy object 5 namely brick, and this heavy object 5 also can select other objects with certain weight such as iron block to replace except selecting brick. The weight of the weight 5 can be adjusted as required. After being pressed on the base 2, the stability of the entire solar cell array can be guaranteed, and it can also be stable when the local extreme wind speed is encountered.

The fixing method of adopting the base 2 and pressing the heavy object 5 on it can avoid the traditional column fixing form, avoid construction on the roof, and cause damage to the roof.

As shown in Fig. 1, in the solar cell support, the support member 1 includes a mounting part 11, a first bending part 12 and a second bending part 13, and the first bending part 12 and the second bending part 13 are respectively located Both ends of section 11. In order for the solar battery module 3 to better receive light and improve its efficiency, the installation part 11 of the support member 1 adopts an inclined design, and its specific angle is determined according to the sunlight angle of the place of use. In order to ensure that the installation part 11 keeps tilting, the length of the first bending part 12 is designed to be shorter, while the length of the second bending part 13 is designed to be longer, so as to achieve the purpose of tilting the installation part 11 . The angle of inclination can be adjusted by adjusting the lengths of the first bending portion 12 and the second bending portion 13 to meet the installation angle requirements of the solar cell module 3 in cities at different latitudes.

The first bending part 12 and the second bending part 13 are fixed on the base 2 , and the solar battery module 3 is installed on the mounting part 11 .

In order to simplify the installation process of the bracket on the roof as much as possible, it is preferable to use the fixing piece 4 to fix the solar battery module 3 on the installation part 11 instead of welding, as shown in FIG. 3 . Of course, welding is also a fixing method, but compared with it, fixing with fixing parts can reduce the process and will not cause noise pollution during the installation process.

As shown in FIG. 3 , the fixing member 4 includes a pressing end 41 and a fixing end 42 , the pressing end 41 presses the solar battery module 3 on the mounting portion 11 , and the fixing end 42 is fixed together with the mounting portion 11 of the supporting member 1 . In this way, there is no need for screw connection or welding on the surface of the solar cell module 3 , and it only needs to be pressed with the pressing end 41 , which avoids drilling or welding on the surface of the solar cell module 3 . In addition, welding or screw connection is also a way to fix the pressing end 41 and the solar cell module 3 , but the process is relatively complicated and may cause adverse effects on the solar cell module 3 .

It can be seen from Fig. 3 that the fixing member 4 is a Z-shaped device, and the two ends of the Z are the pressing end 41 and the fixing end 42 respectively, and the pressing end 41 is pressed on the solar cell module 3 so that it is closely attached to the On the part 11; the fixed end 42 is fixed on the mounting part 11.

At the same time, it is preferable to use the screw 6 to fix the fixing end 42 on the installation part 11, so as to avoid welding and other fixing methods that are likely to have negative effects and are complicated to operate.

During the fixing process, the pressing end 41 of the Z-shaped fixing part 4 presses the solar cell module 3 on the installation part, and the fixing end 42 of the Z-shaped fixing part 4 is provided with an installation through hole; at the same time, the installation part 11 Mounting through holes are also provided at corresponding positions fixedly connected with the fixed end 42 , and during installation, screws are passed through the two through holes to fasten the fixed end 42 on the mounting portion 11 .

In this embodiment, the base 2 is formed by welding the profiles formed by bending the angle steel and the steel plate, and is integrally formed. This design can avoid complex operations such as high-altitude welding, further simplify the installation of the bracket, go out for unnecessary high-altitude operations, and minimize the impact on the normal work and life of surrounding users during installation.

As shown in Fig. 4, the base 2 is a quadrilateral box, and on the premise of ensuring the stability of the entire square array, materials and assembly steps are minimized. Of course, other shapes are also feasible, and the quadrilateral is only a preferred form of this embodiment.

In addition, when assembling in this bracket, most of the structural connections are connected by screws, and welding is used as little as possible, which can reduce the process and reduce the impact on the surroundings. For example, the connection between the first bending portion 12 and the second bending portion 13 and the base 2 is screw connection.

In addition, in this bracket, the support member 1 is integrally formed without assembly or welding, and is integrally formed directly by injection molding, which simplifies the process and increases the assembly efficiency.

In the assembly process, first place the base 2, and then fix the support 1 on the base with screws; then install the solar cell module 3 on the support 1, and fix it with the fixing 4; again, put the assembled support system Arrange them in a square array; finally, place heavy objects 5 on each base 2 of the square array to complete the assembly.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
