Description

A rooftop photovoltaic panel assembly system

technical field

The utility model belongs to the technical field of solar photovoltaic battery accessories, in particular relates to a roof-type photovoltaic battery panel assembly system.

Background technique

Under the premise of human beings chasing and exploring new energy sources, light energy, as the most commonly used new energy source in the 21st century, is gradually improving its technology and application range, and gradually integrating into people's lives.

In order to further improve the utilization rate of light energy in all aspects and optimize people's lives, a plan is proposed to use solar photovoltaic panels directly in the construction of factories, residences and public buildings to replace the roof, which not only effectively uses the roof area for power generation, Moreover, it can reduce the owner's electricity expenses and realize efficient use of energy.

Existing photovoltaic roofs are connected by traditional bracket structures (such as glass embedded), and installed on photovoltaic brackets on flat roofs, which require high technical process and cost. Not only does the roof need to be flat, but there is also a wall blocking that affects the power generation, and the weight of the photovoltaic support body also increases the load-bearing requirements of the roof.

Utility model content

The purpose of the utility model is to provide a roof-type photovoltaic panel assembly system. This product can solve the problems of long construction time, large engineering volume, inconvenient assembly and stress of photovoltaic panel assembly.

Its specific technical plan is:

A roof-mounted photovoltaic panel assembly system, which is composed of multiple internal I-shaped frames and border semi-open frames spliced together, and the frames contain modules with roughly the same structure;

Select the long side on the surface of the area to be assembled as the main axis, and the length of the main axis is the same as the length of the long side of the area. Make a hole on the side of the I-shaped main shaft, the size of the groove at the small hole is approximately matched with the nut (as shown in Figure 2), and pass the screw through it to make it perpendicular to another I-shaped structure with a threaded hole Auxiliary shaft (as shown in Figure 3), the screw is fixed in the threaded hole after passing through the small hole of the main shaft, so as to realize the fixed connection with the main shaft. Except for the semi-open frame at the border (as shown in Figure 5), each frame module for installing photovoltaic panels, including the main shaft and the auxiliary shaft, is open on both sides.

Furthermore, the photovoltaic panel and the frame are spliced in a push-pull manner. The front and rear grooves of the frame are engaged. The width of the plastic on the edge of the board is 2-5cm (as shown in Figure 4).

Further, in order to ensure that when the main shaft and the auxiliary shaft are fixed, the two will not be unable to connect due to the groove size, the groove spacing of the main shaft is greater than the groove spacing of the auxiliary shaft, and the margin is the metal thickness of the two groove boundaries on one side. Make the primary and secondary axes fit well. However, the distance between the grooves of the main shaft will be greater than the thickness of the battery board, resulting in loosening. Therefore, a sealing plastic strip is added to the joint between the main shaft and the battery board at equal intervals to block the gap.

Further, a waterproof layer is provided on the boundary of the groove (as shown in FIG. 5 ).

Compared with the prior art, the beneficial effects of the utility model are:

The utility model glues and connects the solar photovoltaic cell and the assembly system into one. The installation is simple, and a single person can carry out the splicing operation of the solar panel. The construction is simple and convenient, and the assembly speed can be greatly improved. After the splicing is completed, a sealing strip can be inserted at the seam between the battery board and the frame for waterproof and dustproof, and finally bolts are installed at the splicing intersection for fastening. When one of the photovoltaic panels is damaged and needs to be replaced, it is only necessary to pull out the damaged column and replace it. The entire assembly system can be produced in batches only by opening a set of molds, which has the advantages of low cost, easy maintenance, high stress strength, and tight connection.

Detailed ways

The technical solution of the present utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

A roof-mounted photovoltaic panel assembly system is composed of multiple I-shaped frames spliced together, and the same modules are contained in the frame. The plane effect after splicing is shown in Figure 1. (Note: The specific structure of the screw is shown outside)

There is a small hole at the I-shaped main shaft. The structure is shown in Figure 2. The size of the groove at the small hole on the side of the main shaft ① matches the nut, and the screw is passed through to make it perpendicular to another I-shaped structure with a threaded hole. The auxiliary shaft ②, let the screw ③ go through to make it fixedly connected with the main shaft. Except for the semi-open frame at the border shown in Figure 7, the rest of the frames—the main shaft and the auxiliary shaft—are groove openings on both sides. The side view structure of the I-shaped auxiliary shaft is shown in Figure 4, the cross-sectional view after the screw is installed is shown in Figure 5, and the embedded shape is shown in Figure 3.

The battery board and the frame are spliced in a push-pull manner, and the front and back frame grooves are engaged.

The length of the hollow space ⑤ in the middle of the area that is attached to the battery board is consistent with the thickness of the battery board, and the width of the joint part ⑥ meets the edge width of the battery board.

The overall frame structure is composed of multiple I-shaped frame modules in the non-boundary part, semi-open frame modules in the boundary part and a plastic protective sealing layer.

The overall structure of the frame is composed of light but strong metal materials. In the structure of the non-boundary frame part, the cut side of the part is in the shape of "I", as shown in Figure 4 and Figure 6. The grooves on both sides of the I-shaped part ⑦ are matched with the two battery panels respectively. In order to make the frame surrounded by the battery board on all sides, the length of the module of the auxiliary axis of the frame is the same as the short side of the battery board. The middle solid part of the main shaft is drilled to leave a hole for the screw head ⑧, and the central solid part of the auxiliary shaft part of the frame has a threaded hole ⑨ for the screw, which matches the main shaft, as shown in Figure 6. In order to ensure that the two auxiliary shafts on the same axis do not have conflicts of hole occupancy when they are fixed to the main shaft, in the vertical direction, materials such as rubber strips are filled to the beginning of the even-numbered columns, so that the panels of the odd and even columns are slightly staggered by a certain length ④ such as As shown in Figure 1, the staggered length is at least greater than the diameter of the screw nut. The size of the groove outside the small hole on the main shaft approximately matches the nut, so that the nut will not protrude from the main shaft and affect the assembly of the battery board.

The structure on the edges is a semi-open frame, and the panels fit in the same way. In order to make the force on the edge strong enough, fix the screws on the upper and lower sides of the edge structure respectively to the fixed surface wall, as shown in Figure 7.

The battery board is installed in the frame in the horizontal direction in the form of sliding. The upper and lower protrusions of the boundary main shaft structure have the functions of protecting the battery board and facilitating screw fixing.

The area of the solid part in the middle of the main shaft is larger than that of the auxiliary shaft, that is, the area where the threaded hole of the auxiliary shaft is located. The larger width of the solid area ensures the overall stress and flatness of the frame. The groove spacing of the main shaft ⑤ is greater than that of the auxiliary shaft. On the premise that the metal thickness of the groove boundary ⑦ of the main shaft and the auxiliary shaft is consistent, the margin is twice the thickness of the groove boundary, so that the auxiliary shaft can fit the main shaft. However, the main shaft cannot fit tightly with the battery board, so it is necessary to add a sealing strip at the connection between the main shaft and the battery board.

If necessary, sealing strips can be added to the ends of the inner grooves of each auxiliary shaft module to facilitate the fixing of photovoltaic panels and meet the needs of roof waterproof and dustproof.

The actual main axis and auxiliary axis groove boundary ⑦ structure is slightly arc-shaped.

The assembly sequence of the overall system is: the boundary main shaft and the internal main shaft; the first row of battery boards corresponds to the auxiliary shaft; the first row of battery boards corresponds to the auxiliary shaft; (after the first row of battery boards is assembled, the remaining parts repeat the assembly steps of the first row); One side boundary spindle (Note: The installation sequence is a fixed step, otherwise it cannot be installed).

The above is only a preferred embodiment of the utility model, and the scope of protection of the utility model is not limited thereto. Anyone familiar with the technical field can obviously obtain the technology within the technical scope disclosed in the utility model. Simple changes or equivalent replacements of the schemes all fall within the protection scope of the present utility model.
