Description

Technical Field

[0001] This invention relates to the field of photovoltaic technology, and in particular to a three-dimensional photovoltaic support structure. Background Technology

[0002] Building-integrated photovoltaics (BIPV) is a technology that integrates photovoltaic products into buildings, such as photovoltaic roofs and photovoltaic power station fences. Photovoltaic power station fences replace conventional netting or railings with photovoltaic panels, giving the fence both isolation and photovoltaic power generation functions. The support frames for the photovoltaic panels need to be fixed to the ground. However, ground conditions vary, and after the support frames are fixed to the ground, it is difficult to guarantee their verticality and the spacing between them. It is also difficult to pre-install fixing parts or holes for the photovoltaic panels on the support frames. Furthermore, the size and specifications of photovoltaic panels are standardized, so in actual construction and installation, on-site welding or drilling is usually required to fix the photovoltaic panels, making installation cumbersome. In addition, the spacing between the support frames is often too large, making it difficult to install the photovoltaic panels. To solve this problem, it is generally necessary to adjust the support frames or fabricate connectors on-site, which is time-consuming and labor-intensive. Summary of the Invention

[0003] The purpose of this invention is to provide a three-dimensional photovoltaic support structure that is easy and quick to install and has a certain degree of adjustability.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A three-dimensional photovoltaic support structure, comprising:

[0006] Several photovoltaic panels.

[0007] Several columns are arranged in a row at equal intervals.

[0008] Several horizontal bars are placed between two adjacent columns, and the horizontal bars and columns cooperate to form an installation frame for installing photovoltaic panels.

[0009] Several adjusting clamps include a fixed member, a movable member, at least one first locking member and at least one second locking member, wherein the fixed member, the movable member and the first locking member cooperate to clamp the column, and the fixed member is adjustablely connected to the crossbar through the second locking member.

[0010] Several clamping blocks connect the photovoltaic panel and the crossbar.

[0011] Preferably, the column is provided with two protrusions extending along the axial direction, and the two protrusions are in opposite directions; the adjusting clamp is held on the protrusions.

[0012] Preferably, the protrusion includes a first connecting surface, a second connecting surface, and a third connecting surface connected in sequence; the included angle between the first connecting surface and the second connecting surface and the included angle between the second connecting surface and the third connecting surface are both less than 90°; the second connecting surfaces corresponding to the two protrusions on the column are parallel to each other.

[0013] Preferably, the fixing member has a first bending portion and the movable member has a second bending portion, both the first bending portion and the second bending portion are adapted to the shape of the protrusion; the first bending portion and the second bending portion cooperate to clamp the protrusion.

[0014] Preferably, the first locking component includes a first locking screw and a first locking nut, the first locking screw passes through the fixed component and the movable component and is threadedly connected to the first locking nut; the fixed component or the movable component is provided with a first limiting groove that is adapted to the first locking nut.

[0015] Preferably, the movable part is further provided with a protrusion at the end away from the protrusion, and the protrusion abuts against the fixing part.

[0016] Preferably, the second locking member includes a second locking screw and a second locking nut, and the fixing member has a through hole for the second locking screw to pass through; the crossbar has a second limiting groove and an adjustment hole corresponding to the second locking member, the width of the second limiting groove is adapted to the width of the fixing member, and the fixing member is slidably connected in the second limiting groove; the second locking screw passes through the adjustment hole and the through hole and is threadedly connected to the second locking nut.

[0019] Preferably, the system also includes a number of ground piles, each corresponding to a column and bolted together; the ground piles are also provided with clearance grooves; and the edges of the columns are bent to form reinforcing ribs.

[0020] With the above solution, the photovoltaic panels are connected between pairs of adjacent horizontal bars via clamping clips. The horizontal bars provide fixation and support for the photovoltaic panels, while the adjustable clamps connect the horizontal bars to the uprights in an adjustable manner, allowing for a certain degree of adjustability. Even if the distance between pairs of adjacent uprights is large, the connection can still be effectively achieved, ensuring the photovoltaic panels can be installed and avoiding problems such as adjusting the uprights.

[0035] Photovoltaic panel 60. Detailed Implementation

[0036] like Figure 1-8 As shown, the present invention discloses a three-dimensional photovoltaic support structure, which includes: a plurality of ground piles 10, a plurality of photovoltaic panels 60, a plurality of columns 20, a plurality of crossbars 30, a plurality of adjusting clamps 40 and a plurality of clamping blocks 50.

[0037] One end of the ground stake 10 is fixed (through pre-embedding or other methods) to the wall or ground, and the other end of the ground stake 10 extends out of the wall or ground and is bolted to the column 20. Generally, one ground stake 10 corresponds to one column 20. The ground stakes 10 provide sufficient grip for the three-dimensional photovoltaic support structure, ensuring its stability. Of course, for ease of installation, the ground stakes 10 can be omitted, and the column 20 can be directly fixed to the wall or ground.

[0038] The columns 20 are evenly spaced, and each column 20 has two axially extending protrusions 21, with the two protrusions 21 pointing in opposite directions. To ensure the secure installation of the ground piles 10 and the columns 20, the ground piles 10 are provided with clearance grooves 11 that cooperate with the protrusions 21. The protrusions 21 can abut against the clearance grooves 11, thereby ensuring that the ground piles 10 and the columns 20 have sufficient contact area. At the same time, the clearance grooves 11 can also serve as vertical limiters, allowing the columns 20 to remain vertical. The upper adjusting clamp 40 can be clamped onto the protrusion 21. To ensure that the adjusting clamp 40 can be reliably clamped and to facilitate the installation of the adjusting clamp 40, this application defines the protrusion 21 as follows: the protrusion 21 includes a first connecting surface, a second connecting surface, and a third connecting surface connected in sequence, wherein the included angle between the first connecting surface and the second connecting surface is B, and the included angle between the second connecting surface and the third connecting surface is C, then B < 90°, C < 90°. As a further preferred embodiment, B = C. The second connecting surfaces corresponding to the two protrusions 21 on the same column 20 are parallel to each other. The column 20 is formed by bending steel plate. In order to further improve the strength of the column 20, the edge of the column 20 is bent to form reinforcing ribs 22. With this setting, the column 20 is difficult to bend and can provide sufficient support for the guardrail.

[0039] The crossbar 30 is placed between two adjacent columns 20, and the crossbar 30 and the columns 20 cooperate to form an installation frame for installing the photovoltaic panel 60.

[0040] The adjusting clamp 40 includes a fixed part 41, a movable part 42, two first locking parts, and two second locking parts.

[0041] The fixed member 41 has a first bent portion 411 at one end, and the movable member 42 has a second bent portion 421. The first bent portion 411 and the second bent portion 421 are arranged opposite to each other. When the movable member 42 is pressed against the fixed member 41, the first bent portion 411 and the second bent portion 421 cooperate to form a structure that matches the shape of the protrusion 21. The fixed member 41 and the movable member 42 are locked by the first locking member. The first bent portion 411 and the second bent portion 421 cooperate to clamp the protrusion 21 and prevent it from falling off.

[0042] The first locking component includes a first locking screw 431 and a first locking nut 432. The first locking screw 431 passes through the fixed component 41 and the movable component 42 and is threadedly connected to the first locking nut 432, thereby locking the movable component 42 onto the fixed component 41. To facilitate the installation of the first locking nut 432 during construction and to facilitate the tightening of the first locking component, a first limiting groove 422 adapted to the first locking nut 432 is provided on the fixed component 41 or the movable component 42. Due to the restriction of the first limiting groove 422, the first locking nut 432 can only slide in the first limiting groove 422 but cannot rotate. In addition, in order to ensure sufficient clamping force between the first bending portion 411 and the second bending portion 421, a protrusion 423 is provided at the end of the movable member 42 away from the second bending portion 421. The protrusion 423 abuts against the fixing member 41. As the first locking screw 431 is tightened, the protrusion 423 acts as a fulcrum lever, thereby forcing the second bending portion 421 to move closer to the first bending portion 411.

[0043] The fixing member 41 is adjustablely connected to the crossbar 30 via a second locking member. The second locking member includes a second locking screw 441 and a second locking nut 442, and the fixing member 41 has a through hole through which the second locking screw 441 passes. The crossbar 30 has a second limiting groove 31 and an adjusting hole 32 corresponding to the second locking member. The width of the second limiting groove 31 is adapted to the width of the fixing member 41. The fixing member 41 is slidably connected in the second limiting groove 31 and cannot rotate, thus ensuring the stability of the crossbar 30. The second locking screw 441 passes through the adjusting hole 32 (elongated hole) and the through hole and is threadedly connected to the second locking nut 442. By adjusting the position of the second locking screw 441 in the adjusting hole 32, the distance between the column 20 and the crossbar 30 can be adjusted.

[0044] The clamping fixture 50 is used to connect the photovoltaic panel 60 and the crossbar 30, ensuring that the photovoltaic panel 60 can be securely installed in the mounting frame. Generally, two to three sets of clamping fixtures 50 are installed along the upper edge of the photovoltaic panel 60, and two to three sets along the lower edge of the photovoltaic panel 60. The clamping fixture 50 includes a first clamping block 51 and a second clamping block 52. The first clamping block 51 is secured to the crossbar 30 with screws, and the second clamping block 52 is secured to the first clamping block 51 with screws. The first clamping block 51 and the second clamping block 52 cooperate to clamp the edge of the photovoltaic panel 60. Normally, the photovoltaic panel 60 has a metal outer frame. The clamping fixture 50 holds the photovoltaic panel 60 in place by the metal outer frame, preventing damage to the functional areas of the photovoltaic panel 60 while ensuring that the light-receiving area is not obstructed, thus maximizing the light-receiving area of ​​the photovoltaic panel 60. In addition, a slot 511 is provided on the side of the first card block 51 where the photovoltaic panel 60 contacts. A rubber pad is installed in the slot 511 to prevent the photovoltaic panel 60 from sliding.

[0045] The key to this invention lies in the fact that the photovoltaic panel 60 is connected between two adjacent horizontal bars 30 via clamping blocks 50. The horizontal bars 30 provide fixation and support for the photovoltaic panel 60, while the horizontal bars 30 are adjustablely connected to the uprights 20 via adjusting clamps 40, allowing for a certain degree of adjustability. Even if the distance between two adjacent uprights 20 is large, the connection can still be effectively achieved, ensuring the photovoltaic panel 60 can be installed. This avoids the problem of adjusting the uprights 20, making construction and installation more convenient and faster, shortening the construction cycle, and facilitating the disassembly and maintenance of the photovoltaic panel 60. This invention can be used not only as a fence but also as a photovoltaic power station, offering flexible applications.

[0046] The above description is merely an embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
