Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a photovoltaic support structure with a large bottom space. Background Technology

[0002] As photovoltaics become more and more common, many people install photovoltaic modules on rooftops or building walls to supply power to the grid. Photovoltaic brackets are mainly used to install photovoltaic solar panels.

[0003] A search revealed a patent, CN219893222U, which discloses a photovoltaic support system. The system includes a base with two seat rods connected and fixed by two connecting rods. A pile rod is hinged to the left side of the top of each seat rod, and two displacement components are movably connected to the surface of the pile rod. A web member assembly is movably connected to the right side of the top of each seat rod, with its top end movably connected to the pile rod. A support assembly is located on the left side of the top of the pile rod. This invention supports the pile rod by adjusting the length of the support shaft inside the outer shaft cylinder. A reinforcing component is installed between the support shaft and the concrete pier. This allows the inner screw rod to move relative to itself and adjust to a suitable length to provide force support to the support shaft. This creates a triangular stable structure between the support shaft, the outer shaft cylinder, and the seat rods, reducing the load at the connection between the support shaft and the pile rod, and decreasing the likelihood of cracking at the connection point.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] Photovoltaic solar panels are installed on the top floor of residential buildings, where they can generate electricity and provide some shade. However, in the aforementioned comparative documents, if the photovoltaic brackets are installed on the top floor of a residential building, the space underneath them is too small to allow people to walk under the installed brackets, which affects the lives of residents and reduces the practicality of the photovoltaic brackets. Therefore, there is an urgent need in this field to improve the photovoltaic brackets in order to overcome the shortcomings of the existing technology. Utility Model Content

[0006] The purpose of this utility model is to provide a photovoltaic support bracket with a large bottom space, which solves the technical problem that the space under the traditional bracket is too small, making it impossible to walk under the installed photovoltaic bracket, which has a certain impact on the lives of residents in residential buildings and reduces the practicality of the photovoltaic bracket.

[0007] To achieve the above objectives, the present invention adopts the following technical solution.

[0008] A photovoltaic support structure with a large bottom space includes several bases with open tops. Each base has a support seat, and the support seat has a main load-bearing column on top. An inclined top beam is fixedly installed between the upper ends of the main load-bearing columns. Several connecting rods are fixedly installed between several adjacent top beams. A support rod is provided between the lower side of the top beam and the side of the main load-bearing column. Adjustment units capable of adjusting the position of the support seat are provided on multiple sides of the base.

[0009] Preferably, each adjustment unit includes an adjustment threaded rod that passes through several sides of the base. Threaded rings are provided on several sides of the base. The threaded rings are threadedly connected to the adjustment threaded rod. One end of the adjustment threaded rod abuts against the side of the support base. A limit nut for limiting the position is threadedly connected to the side of the adjustment threaded rod.

[0010] Preferably, a limiting ring is fixedly connected to the side of the threaded ring, and the threaded ring and the limiting ring are pre-embedded inside the side of the base.

[0011] Preferably, the lower end of the support base has multiple abutment holes on its sides, which are adapted to the end of the adjusting threaded rod.

[0012] Preferably, the support base has a first through hole on the opposite side, and the main bearing column has a second through hole on the lower side that matches the first through hole. Fixing bolts pass through the second through hole and the first through hole.

[0013] Preferably, reinforcing plates are fixedly installed at both ends of the support rod, and the two reinforcing plates are fixedly installed to the side of the main load-bearing column and the top beam, respectively.

[0014] Preferably, the base is filled with concrete.

[0015] Compared with the prior art, the present invention has the following features and beneficial effects.

[0016] 1. The height of the main support column in this utility model can be selected and determined according to the actual situation, as long as it does not obstruct the passage of residents in the residential building. After the photovoltaic panel is installed on the roof of the residential building, it will not affect the normal life of the residents in the residential building. The photovoltaic panel also provides a certain shading effect. At the same time, the straightness between several support seats can be installed through the adjustment unit, which facilitates the installation of the overall bracket and the position adjustment during installation, improves the practicality of the photovoltaic bracket, and facilitates the installation of the photovoltaic bracket.

[0017] 2. In this utility model, when it is necessary to adjust the height of the main support column, the first through hole and the second through hole at the appropriate position are aligned, and one or more fixing bolts are passed through the first through hole and the second through hole. The position between the support base and the main support column is fixed by the fixing bolts, which makes it easy to adjust the height of the main support column according to the actual situation, thereby improving the applicability and practicality of the photovoltaic bracket.

[0018] 3. After the overall bracket is installed, concrete can be poured into the base to make the support and the base a whole, thereby improving the overall strength of the photovoltaic bracket after installation. Attached Figure Description

Detailed Implementation

[0028] like Figure 1-7As shown, this large-space photovoltaic support includes several open-top concrete supports 1, each containing a support base 2. A main load-bearing column 3 is located on top of each support base 2. Inclined top beams 4 are fixedly installed between the upper ends of the main load-bearing columns 3. Several connecting rods 5 are fixedly installed between adjacent top beams 4. Support rods 6 are located between the lower side of the top beams 4 and the side of the main load-bearing columns 3. Multiple sides of the concrete supports 1 are equipped with adjustment units capable of adjusting the position of the support base 2. Each adjustment unit includes an adjusting threaded rod 7 penetrating multiple sides of the concrete supports 1. Multiple sides of the concrete supports 1 are equipped with threaded rings 8, which are threadedly connected to the adjusting threaded rods 7. One end of the adjusting threaded rod 7 abuts against the side of the support base 2, and a limiting nut 9 for limiting the position is threadedly connected to the side of the adjusting threaded rod 7.

[0029] In this embodiment, when solar photovoltaic panels need to be installed on the roof of a residential building, the installation position of the photovoltaic bracket is determined, and concrete supports 1 of suitable position and quantity are poured on the roof by pouring concrete. During the pouring of the concrete supports 1, threaded rings 8 are pre-embedded in the side of the concrete supports 1. The upper part of the concrete supports 1 is open. After the concrete has cured, the lower end of the support 2 is placed inside the concrete supports 1, and the adjusting threaded rods 7 are threaded into the threaded rings 8. By rotating several adjusting threaded rods 7, the ends of the adjusting threaded rods 7 are pressed against the lower side of the support 2, and the horizontal and vertical positions of several support 2s are adjusted by adjusting the threaded rods 7. The locking limit nut 9 limits and fixes the position of the adjusting threaded rods 7. The main load-bearing column 3 is installed on the upper part of the support 2. Subsequently, a top beam 4 at a certain angle is welded or bolted to the upper end of several main load-bearing columns 3. Several connecting rods 5 are installed between adjacent top beams 4 by welding or bolting. The connecting rod 5 improves the stability of the overall bracket after installation. The support rod 6 is fixed between the top beam 4 and the main load-bearing column 3 by welding or bolting. The support rod 6 is inclined to support the top beam 4 and improve its support strength. The upper sides of several connecting rods 5 are flush with the upper side of the top beam 4, and the position of the connecting rods 5 can be adapted to the size of the photovoltaic panel. The photovoltaic panel is fixed to the top beam 4 and the upper part of the connecting rods 5 with bolts to complete the installation of the photovoltaic panel. The height of the main load-bearing column 3 can be selected according to the actual situation, as long as it does not obstruct the passage of residents in the building. With the above structure, after the photovoltaic panel is installed on the roof of the residential building, it will not affect the normal life of the residents in the building, and the photovoltaic panel provides a certain shading effect. At the same time, the straightness between several support seats 2 can be adjusted by adjusting the threaded rod 7, which facilitates the installation of the overall bracket and the position adjustment during installation, improves the practicality of the photovoltaic bracket, and facilitates the installation of the photovoltaic bracket.

[0030] In this embodiment, a limiting ring 10 is fixedly connected to the side of the threaded ring 8. The threaded ring 8 and the limiting ring 10 are embedded inside the side of the concrete support 1. Multiple abutment holes 11 are opened on the lower side of the support 2. The abutment holes 11 are adapted to the end of the adjusting threaded rod 7. Before pouring concrete for the concrete support 1, the threaded ring 8 and the limiting ring 10 are embedded in the side of the concrete support 1. The concrete support 1 is formed on-site by formwork or made by factory prefabrication. When adjusting the position of the support 2, one end of the adjusting threaded rod 7 is inserted into the abutment hole 11. The abutment hole 11 limits the position of the end of the adjusting threaded rod 7 to prevent the support 2 from moving upward and improve the stability of the support 2 after it is positioned.

[0031] In this embodiment, a first through hole 12 is provided on the opposite side of the support base 2, and a second through hole 13 adapted to the first through hole 12 is provided on the lower side of the main support column 3. Fixing bolts 14 pass through the second through hole 13 and the first through hole 12. When it is necessary to adjust the height of the main support column 3, the first through hole 12 and the second through hole 13 at the appropriate positions are aligned, and one or more fixing bolts 14 are passed through the first through hole 12 and the second through hole 13. The position between the support base 2 and the main support column 3 is fixed by fixing bolts 14, which makes it easy to adjust the height of the main support column 3 according to the actual situation, thereby improving the applicability and practicality of the photovoltaic bracket.

[0032] In this embodiment, reinforcing plates 15 are fixedly installed at both ends of the support rod 6. The two reinforcing plates 15 are fixedly installed to the sides of the main bearing column 3 and the top beam 4, respectively. The reinforcing plates 15 are installed and fixed by welding or bolting to increase the area of ​​the support point and thus improve the overall strength of the photovoltaic bracket after installation.

[0033] In this embodiment, concrete is poured into the concrete support 1. After the overall bracket is installed, concrete can be poured into the concrete support 1 to make the support base 2 and the concrete support 1 a whole, thereby improving the overall strength of the photovoltaic bracket after installation.
