Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic technology, and particularly relates to a rigid-flexible combined household photovoltaic support system. Background Technique

[0002] With the gradual reform of the traditional coal-fired power generation industry, solar power generation has gradually become a new direction in the field of new energy power generation. In recent years, the distributed photovoltaic power generation vigorously promoted by the state has gradually been implemented across the country. As a relatively large part of the distributed photovoltaic industry, the popularization and use of roof photovoltaic power generation have made corresponding contributions to solar power generation. As an indispensable part of the roof photovoltaic system, the roof photovoltaic support is one of the important components for supporting photovoltaic modules. Its form and cost also affect the popularization and specific layout of roof photovoltaic. Photovoltaic supports can be divided into fixed type and rotary type. Fixed supports can receive solar radiation according to a preset inclination angle. Generally, it is more convenient to lay distributed photovoltaics on flat roofs, and they can be directly placed on the roof to lay the photovoltaic system. For pitched roofs, especially traditional cast-in-place concrete pitched roofs, glazed tile pitched roofs, or purlin roofs, because the support system is relatively complex, it is not suitable to directly lay photovoltaic panels on the roof, and a corresponding support system needs to be set up to build a roof distributed photovoltaic power generation system. In the system of glazed tile pitched roofs, setting up a support system generally requires lifting the glazed tiles and drilling holes to stably set the support pedestals. The installation of the photovoltaic panel system is complicated, and due to frequent drilling on the inclined roof, it will more or less cause roof leakage. Content of the Utility Model

[0003] The purpose of the utility model is to provide a rigid-flexible combined household photovoltaic support system to solve the technical problems pointed out in the background technique.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0005] A rigid-flexible combined household photovoltaic support system includes a photovoltaic support arranged on the north and south slopes of a house, a triangular diagonal brace for fixing the photovoltaic support on the north and south slopes of the house, and a tension cable assembly that cooperates with the photovoltaic support and the triangular diagonal brace to tension and fix the photovoltaic support on the north and south slopes of the house.

[0006] Further, the photovoltaic support includes a first support erected on the sunny side roof surface and a second support erected on the shady side roof surface. The first support extends upward along the slope direction with an extension section. The upper end of the second support is hinged and cooperated with the bottom of the first support. A roof diagonal brace is obliquely braced between the extension section and the second support. The upper end of the roof diagonal brace is hinged and cooperated with the end of the extension section, and the lower end is hinged and cooperated with the upper part of the second support. A triangular support structure is formed among the extension section, the roof diagonal brace, and the second support.

[0007] Further, a number of support pedestals are fixed to the bottoms of the first support and the second support, and the support pedestals are placed on the roofing tiles.

[0008] Further, eaves sections extend downward along the slope direction at the lower ends of the first support and the second support, and the triangular braces are symmetrically arranged between the eaves sections of the first support and the second support and the vertical wall of the house.

[0009] Further, the triangular brace includes a diagonal brace and a cross brace. One end of the diagonal brace is hinged to the vertical wall of the house, and the other end is hinged to the eaves section of the support. One end of the cross brace is hinged to the middle section of the diagonal brace, and the other end is hinged to the vertical wall of the house.

[0010] Further, the tension cable assembly includes a prestressed cable. A tension hole allowing the prestressed cable to pass through movably is arranged along the length direction inside the first support. After the prestressed cable passes through the tension hole movably, one end is wound and fixed to the triangular brace on the sunny side, and the other end passes through the eaves section of the second support and is wound and tensioned and fixed to the triangular brace on the shady side.

[0011] Further, a triangular structure is formed among the diagonal brace, the cross brace and the vertical wall of the house. The included angle between the diagonal brace and the vertical wall of the house is not higher than 60°, and the number of turns of the prestressed cable wound around the diagonal brace and the cross brace is not less than two turns.

[0012] Further, the pre-tightening force of the prestressed cable is not less than 1 KN.

[0013] Further, a sloping roof photovoltaic guide rail is vertically arranged on the first support, and a photovoltaic panel is fixedly arranged on the sloping roof photovoltaic guide rail.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] Under the action of wind load or other external forces, the support system jointly constituted by the first support, the second support, the roof diagonal brace and the triangular brace first bears and disperses these forces. At the same time, through its tensioning action, the prestressed cable further enhances the overall rigidity and stability of the support system, enabling the entire household photovoltaic support system to more effectively resist the influence of external forces, ensuring the safe operation of the photovoltaic panel, and the overall photovoltaic support is convenient to install, without punching holes on the tile roof, eliminating the situation that the installation of the previous photovoltaic support system is prone to cause roof leakage.

[0024] As Figure 1-2 shown, a rigid-flexible combined photovoltaic household bracket system includes a photovoltaic bracket arranged on the north and south slopes of a house, a triangular diagonal brace 5 for fixing the photovoltaic bracket on the north and south slopes of the house, and a tension cable assembly that cooperates with the photovoltaic bracket and the triangular diagonal brace 5 to tension and fix the photovoltaic bracket on the north and south slopes of the house.

[0025] Specifically, as shown in the figure, the photovoltaic bracket includes a first bracket 1 erected on the sunny side roof surface and a second bracket 2 erected on the shady side roof surface. The first bracket 1 extends upward along the slope direction with an extension section. The upper end of the second bracket 2 is hinged and cooperated with the bottom of the first bracket 1. A roof diagonal brace 3 is obliquely supported between the extension section and the second bracket 2. The upper end of the roof diagonal brace 3 is hinged and cooperated with the end of the extension section, and the lower end is hinged and cooperated with the upper part of the second bracket 2. A triangular support structure is formed among the extension section, the roof diagonal brace 3, and the second bracket 2.

[0026] The first bracket 1 is installed on the sunny side roof surface, while the second bracket 2 is installed on the shady side roof surface. The first bracket 1 extends upward along the slope direction with an extension section. This extension section is connected to the upper end of the second bracket 2 in a hinged manner to form a preliminary support framework. To enhance the connection strength between the first bracket 1 and the second bracket 2, a roof diagonal brace 3 is particularly provided between the extension section and the second bracket 2. The upper end of the roof diagonal brace 3 is hinged to the extension section, and the lower end is hinged to the upper part of the second bracket 2. The three together form a stable triangular support structure, effectively resisting the impact from wind and other external factors.

[0027] Specifically, as shown in the figure, several support pedestals 4 are fixed to the bottoms of the first support 1 and the second support 2, and the support pedestals 4 are placed on the roofing tiles. The lower ends of the first support 1 and the second support 2 both extend downward along the slope direction to form eaves sections. The triangular braces 5 are symmetrically arranged between the eaves sections of the first support 1 and the second support 2 and the vertical wall of the house. The triangular brace 5 includes a diagonal brace 51 and a cross brace 52. One end of the diagonal brace 51 is hinged to the vertical wall of the house, and the other end is hinged to the eaves section of the support. One end of the cross brace 52 is hinged to the middle section of the diagonal brace 51, and the other end is hinged to the vertical wall of the house.

[0028] The bottoms of the first support 1 and the second support 2 are only placed on the roofing tiles through the support pedestals 4 without drilling holes, eliminating the situation of roof leakage. To further enhance the stability of the support system, symmetric triangular braces 5 are arranged between the eaves sections of the support and the vertical wall of the house. The triangular brace 5 is composed of a diagonal brace 51 and a cross brace 52. One end of the diagonal brace 51 is hinged to the vertical wall of the house, and the other end is hinged to the eaves section of the support; the cross brace 52 connects the middle section of the diagonal brace 51 and the vertical wall of the house to form a stable triangular support, effectively dispersing and resisting wind loads.

[0029] Specifically, as shown in the figure, the tension cable assembly includes a prestressed cable 6. A tension hole allowing the prestressed cable 6 to pass through movably is arranged along the length direction inside the first support 1. After the prestressed cable 6 passes through the tension hole movably, one end is wound and fixed to the triangular brace 5 on the sunny side, and the other end passes through the eaves section of the second support 2 and is wound and tensioned and fixed to the triangular brace 5 on the shady side. A triangular structure is formed between the diagonal brace 51, the cross brace 52 and the vertical wall of the house. The included angle between the diagonal brace 51 and the vertical wall of the house is not higher than 60°, and the number of turns of the prestressed cable 6 wound around the diagonal brace 51 and the cross brace 52 is not less than two turns.

[0030] The core of the tension cable assembly is the prestressed cable 6, which passes through movably along the length direction of the first support 1 and is fixed through the tension hole. One end of the prestressed cable 6 is wound and fixed to the triangular brace 5 on the sunny side, and the other end passes through the eaves section of the second support 2 and is wound and tensioned and fixed to the triangular brace 5 on the shady side. This design not only enhances the overall rigidity of the support system, but also makes the entire support system fit more closely on the roof through the tension of the prestressed cable 6, improving the wind resistance and stability, and realizing the rigid-flexible combination fixation of the photovoltaic support.

[0031] Specifically, as shown in the figure, the pre-tightening force of the prestressed cable 6 is not less than 1 KN.

[0032] Specifically, as shown in the figure, a photovoltaic guide rail 7 for a pitched roof is vertically arranged on the first support 1, and a photovoltaic panel 8 is fixedly arranged on the photovoltaic guide rail 7 for a pitched roof.

[0033] Under the action of wind load or other external forces, the support system composed of the first bracket 1, the second bracket 2, the roof brace 3 and the triangular brace 5 first bears and disperses these forces. At the same time, through its tensioning action, the prestressed cable 6 further enhances the overall rigidity and stability of the bracket system, enabling the entire household photovoltaic bracket system to more effectively resist the influence of external forces, ensuring the safe operation of the photovoltaic panels, and the overall photovoltaic bracket is convenient to install without punching holes on the tile roof, eliminating the situation that the installation of the previous photovoltaic bracket system easily causes roof leakage.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
