Detailed ways

In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific embodiments, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

The reference signs in the drawings include: outer frame 1, inner frame 2, connecting bar 3, accommodating frame 4, support tube 5, photovoltaic panel 6, fixing sleeve 7, horizontal U-shaped clip 8, inverted U-shaped clip Block 9, photovoltaic panel fixing column 10, protective cap 11, horizontal combination frame 12, corner combination frame 13, vertical combination frame 14

Examples are shown in Figures 1, 2 and 3:

The prefabricated semi-finished photovoltaic base includes an outer frame 1 and an inner frame 2, the inner frame 2 is arranged inside the outer frame 1, and the inner frame 2 and the outer frame 1 are connected by a connecting bar 3, and a receiving frame 4 is arranged on the connecting bar 3. The outer frame 1, the inner frame 2, the connecting bars 3 and the accommodating frame 4 together form a photovoltaic base frame for pouring concrete.

The accommodating frame 4 is vertically clamped with a supporting tube 5, and the supporting tube 5 adopts a square steel pipe that can be closely fitted with the accommodating frame 4. One of the overlapping positions of the square steel pipe and the accommodating frame is symmetrically provided with a first penetrating two sides. The through hole and the second through hole are connected by a connecting piece.

As shown in FIG. 4 , the top of the support tube 5 is provided with a clamping assembly, and the clamping assembly includes an inverted U-shaped clamping block 9 connected to the top of the supporting tube 5 and a horizontal U-shaped clamping block 9 arranged on the inverted U-shaped clamping block 9 The connection between the clamping block 8 , the inverted U-shaped clamping block 9 and the support pipe 5 is completed through the connecting piece passing through the fourth through hole of the inverted U-shaped clamping block 9 and the third through hole of the supporting pipe 5 . A fixing sleeve 7 is fixedly connected to the horizontal U-shaped clamping block 8 , the fixing sleeve 7 is connected with a photovoltaic panel fixing column 10 with an inner thread, and a protective cap 11 is connected with an outer thread of the fixing sleeve 7 .

The space inside the horizontal U-shaped block 9 can be inserted into the photovoltaic panel. When the photovoltaic panel fixing column 10 is tightened, the photovoltaic panel can be pressed and fixed in the horizontal U-shaped block 8 . In addition, a fixing gasket can also be arranged at one end of the fixing column 10 of the photovoltaic panel 6 close to the photovoltaic panel. The fixing gasket can increase the contact area between the fixing column 10 of the photovoltaic panel and the frame of the photovoltaic panel 6, so that the frame of the photovoltaic panel 6 is more stressed. uniform in order to better protect the photovoltaic panel 6 .

The heights of the two support tubes 5 on the same side of the base frame are the same, and have a height difference with the square steel tube on the other side. According to the width of the photovoltaic panel 6 and the needs of the optimal sunlight inclination angle of the photovoltaic panel, the squares on both sides of the high and low sides are preset by setting the height. The distance and height difference of the steel pipe can accurately locate the distance between the clamping components on both sides of the upper and lower sides, so as to meet the installation requirements of photovoltaic panels 6 of different widths and angles.

Concrete is then poured on site between the outer frame 1 and the inner frame 2 of the base frame, and the concrete is leveled flush with the edge of the base frame. After the concrete is solidified, it forms a strong bond with the original concrete roof under the base frame. In addition to the weight of the concrete in the base frame, the concrete bond and the entire floating beam type frame structure affect the firmness of the entire base frame. played a more important role. At the same time, the connecting bar 3 and the accommodating frame 4 are also surrounded by concrete, and both the connecting bar 3 and the accommodating frame 4 are located within the upper and lower edges of the outer frame and the inner frame, so the concrete in the base frame will not be surrounded by the connecting bar 3 and the accommodating frame. 4 partition and affect the integrity of the entire concrete base frame. After the concrete is solidified, each square steel pipe is completely fixed and cannot be pulled out, and the direction, verticality and height of the square steel pipe are precisely positioned.

Then, a clamping assembly for clamping the photovoltaic panel 6 is installed on the top of each square steel pipe. The top of the square steel pipe is set to a slope suitable for the photovoltaic panel 6, and third through holes are symmetrically left on both sides. After aligning with the fourth through hole on the inverted U-shaped block 9 in the clamping assembly, the connector can be fixed on the top of the square steel pipe through the through hole, and then the photovoltaic panel 6 is clamped on the horizontal U-shaped block 8. In the middle, the photovoltaic panel 6 can be fixed after tightening the photovoltaic panel fixing column 10 . FIG. 5 shows the state in which the base frame is completed by concrete pouring.

In addition, a certain gap can be left between the inverted U-shaped clamping block 9 and the top of the square steel pipe, so that the clamping assembly can swing up and down at a certain angle, which is better for installation when fixing the photovoltaic panel 6 .

If the photovoltaic panel 6 for double-sided power generation needs to be installed, spray or install a reflective material that can improve the efficiency of photovoltaic power generation on the concrete surface of the base frame. Because the base frame is relatively low and flat, there is no obstruction between the base frame and the photovoltaic panel 6 Therefore, it is better to add reflective materials on the concrete surface and the middle position of the base frame, while the traditional cement pier is much higher than the base frame of the present invention, and each independent distribution is relatively scattered, so it is not easy to achieve this function.

In some areas with frequent typhoons, in order to obtain a more secure safety guarantee, other square steel pipes can also be used to connect the square steel pipes in the base frame in the horizontal direction to form an overall frame structure. The clamping assembly can also be used to fix the photovoltaic guide rail first and then install the photovoltaic panel 6 on the photovoltaic guide rail to meet different user requirements.

In another embodiment of the present invention, the base frame may also be formed by connecting a plurality of combination frames, and the combination frame also includes an outer frame 1 , an inner frame 2 , a connecting bar 3 , or a accommodating frame 4 . As shown in FIG. 6 , the base frame is formed by connecting a plurality of horizontal combination frames 12, corner combination frames 13, and vertical combination frames 14, including a horizontal combination frame 12 symmetrically arranged up and down, a vertical combination frame 14 arranged symmetrically on the left and right, and The corner combination frame 13 at the corner of the base frame, the two ends of the corner combination frame 13 are respectively connected with the horizontal combination frame 12 and the vertical combination frame 14, the combination frames are fixed by connecting pieces, the horizontal combination frame 12, the corner combination frame 13, the vertical combination frame 14 After the frame 14 is connected in a circle, an integral base frame can be formed, and the same effect can also be achieved according to the implementation steps of the previous embodiment. Using the combination frame connection method, the length and width of the base frame can be adjusted only by adjusting the size of the horizontal combination frame or the vertical combination frame, so that the production size of the base frame is more flexible, the installation and carrying are more convenient, and the application area is wider.

The invention improves the bonding force by increasing the bonding area between the concrete and the ground, and at the same time, the frame structure connected into a floating beam type can improve the height of the center of gravity when the entire base is lifted, only a lower base frame is required, and the total consumption of concrete is reduced. At the same time, it can satisfy the firmness of the base frame mechanically, and has the advantage of light weight. In addition, it can be made by mold and assembled, which can realize mass production and more accurate size. It can not only improve the installation speed, but also improve the installation accuracy and quality. At the same time, the roof after installation is more integrated and beautiful.
