Detailed Implementation

[0023] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0024] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer" used in the description of specific embodiments of this utility model to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0026] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0027] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0028] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0029] Example 1 like Figures 1-6As shown, a photovoltaic mounting bracket for reverse slope installation includes a support frame 1 and mounting brackets 4. The support frame 1 includes a horizontal bracing frame 11, with several columns 12 at the bottom of the horizontal bracing frame 11. Each column 12 is detachably connected to a counterweight 2. The counterweights 2 are arranged in an array along the slope surface 3, with the counterweights 2 partially embedded in the slope surface 3. Several mounting brackets 4 are arranged laterally at intervals along the slope surface 3. The mounting bracket 4 includes a top support member 41, with at least two support rods 42 arranged at the bottom of the top support member 41. The support rods 42 are vertically arranged, with one end detachably connected to the top support member 41 and the other end detachably connected to the horizontal bracing frame 11. The length of the support rod 42 near the top of the slope of each mounting bracket 4 is shorter than the length of the support rod 42 near the bottom of the slope. The tops of adjacent mounting brackets 4 are overlapped with purlins 43, and several mounting fasteners 5 for limiting and fixing photovoltaic panels 50 are provided on the purlins 43.

[0030] The support frame 1 is used to set on the slope 3 to provide support for the installation frame 4. The installation frame 4 is set on the support frame 1. The photovoltaic panel 50 is installed on the top of the installation frame 4 through the mounting fastener 5. In use, the support frame 1, the installation frame 4 and the photovoltaic panel 50 are set from bottom to top in sequence, that is, the counterweight 2, the column 12, the cross brace frame 11, the support rod 42, the top support rod 41, the purlin 43 and the photovoltaic panel 50 are set from bottom to top in sequence, forming a support structure with multiple vertical rods. This can distribute the load of the photovoltaic panel 50 to the support points of multiple counterweights 2, so as to achieve the stable setting of the photovoltaic panel 50 on the slope 3.

[0031] In an optional embodiment, the support frame 1 and the mounting frame 4 are connected vertically, and the number and distribution of counterweights 2 can be flexibly increased or decreased according to the actual situation to adjust the load-bearing capacity of the photovoltaic support, so that the photovoltaic support can adapt to the environment of the slope 3 and achieve stable support of the photovoltaic panel 50 on the slope 3.

[0032] In an optional embodiment, the bottom end of the support rod 42 is detachably connected to the cross brace frame 11. The tilt direction of the top surface of the mounting frame 4 can be adjusted by adjusting the length of the support rod 42, thereby changing the tilt direction of the photovoltaic panel 50 on the slope 3 and enabling the photovoltaic panel 50 to be installed in reverse on the slope 3. This makes the installation of the photovoltaic panel 50 unaffected by the terrain, reduces the installation cost of the photovoltaic panel 50, and improves the installation efficiency. Furthermore, since the counterweight 2 does not require large-area excavation of the slope 3, it can reduce environmental interference to the slope 3, making the photovoltaic bracket adaptable to complex geological conditions such as plateaus, permafrost, and rock layers.

[0033] In an optional implementation, the column 12 can be adjusted in length according to the slope of the slope 3 and the terrain, so that the cross bracing frame 11 is relatively horizontal, which can provide a flat and horizontal support foundation for the installation of the upper mounting frame 4, reducing the requirements of the terrain for the installation of photovoltaic panels 50.

[0034] In an optional implementation, the counterweight 2 can be a precast concrete pier, and the counterweight 2 is in the shape of a quadrangular prism. The weight and quantity of the counterweight 2 can be designed and calculated based on the actual photovoltaic modules and the usage environment to meet the load-bearing capacity requirements. The counterweight 2 can be partially embedded in the slope 3, which has less impact on the original structure of the slope 3 but is more efficient than excavating and setting foundation structures such as pile foundations.

[0035] In an optional embodiment, the counterweight 2 may be provided with an insulation layer 6. The insulation layer 6 may cover the top surface of the counterweight 2 and extend partially to the shading slope 3. The insulation layer 6 can isolate the slope 3 from the external environment, so that the environment in the area where the counterweight 2 is located changes less and is not easily affected by the external environment. It can maintain the contact state between the slope 3 and the counterweight 2, and avoid the counterweight 2 from separating from the slope due to freeze-thaw cycles caused by external influences. This allows the photovoltaic support to be better adapted to use in high-altitude and cold regions.

[0036] In an optional implementation, the counterweight 2 can be made of precast antifreeze concrete to reduce the impact of ambient temperature on the counterweight 2.

[0037] In optional implementations, such as Figure 1 As shown, a pre-embedded connector 21 is provided at the top of the counterweight 2, and a connecting part 13 is provided at the bottom of the column 12. The connecting part 13 is detachably connected to the pre-embedded connector 21. The pre-embedded connector 21 can be an anchor bolt, which partially protrudes from the top of the counterweight 2. The connecting part 13 can be a perforated flange plate provided at the bottom of the column 12. Through the assembly and connection of the pre-embedded connector 21 and the connecting part 13, the column 12 can be quickly installed on the counterweight 2, thereby improving the overall installation efficiency of the photovoltaic bracket.

[0038] In one or more implementations, such as Figure 2 , Figure 3 As shown, the bottom of the top support member 41 is detachably connected to multiple first transition blocks 7, the top of the cross support frame 11 is provided with several second transition blocks 8, the support rod 42 is detachably connected to the vertically corresponding first transition blocks 7 and second transition blocks 8, and a third transition block 9 can also be detachably provided on several support rods 42. The third transition block 9 is connected to the bottom of the top support member 41 and the first transition block 7 is provided diagonally in the same direction as it is at the bottom through the diagonal support member 44, and the diagonal support member 44 is in the same or similar direction to the slope 3.

[0039] In optional implementations, such as Figure 2 As shown, the first adapter block 7 can be a perforated ear plate bolted to the top support rod 41, and the second adapter block 8 can be a component bolted or welded to the top of the cross brace frame 11. The support rod 42 is vertically arranged, with one end hinged to the first adapter block 7 and the other end bolted to the second adapter block 8, so that both ends of the support rod 42 are respectively limited, resulting in high assembly and installation efficiency and easy replacement, which can reduce the later maintenance cost of the photovoltaic bracket.

[0040] In optional implementations, such as Figure 3 As shown, the second adapter block 8 can be a component composed of a base plate and a vertical L-shaped limiting plate. It can be welded or bolted to the top surface of the cross brace frame 11 through the base plate to achieve a stable connection with the cross brace frame 11. The support rod 42 can be partially clamped by the vertical L-shaped limiting plate and limited by bolts, which facilitates assembly and disassembly.

[0041] In optional implementations, such as Figure 3 As shown, the third adapter block 9 can be a perforated lug bolted to the support rod 42, with a structure similar to the first adapter block 7. One end of the diagonal brace 44 is hinged to the first adapter block 7, which is obliquely positioned at the bottom of the top support rod 41, and the other end is hinged to the third adapter block 9 on the side wall of the support rod 42. The position of the first adapter block 7 can be adjusted according to the actual situation of the slope 3, thereby adjusting the support angle of the diagonal brace 44, thus achieving stable support for the top support rod 41, making the structure of the single mounting frame 4 stable, and able to stably support the installation of the upper purlin 43 and photovoltaic panel 50.

[0042] In one or more implementations, such as Figure 4 As shown, connecting rods 10 are inclined between adjacent mounting frames 4 along the slope 3, with adjacent connecting rods 10 inclined in opposite directions. The connecting rods 10 are used to connect adjacent mounting frames 4 into one unit, realizing the mutual transfer of structural forces between adjacent mounting frames 4, making the overall structure of the photovoltaic support more stable.

[0043] In an optional embodiment, a reinforcing rod 20 is provided between the column 12 and the cross brace frame 11. The reinforcing rod 20 can structurally strengthen the support frame 1, further improving the overall structural stability of the photovoltaic bracket. The reinforcing rod 20 can be obliquely connected at the corner where the column 12 and the cross brace frame 11 intersect.

[0044] In one or more embodiments, the column 12, the cross brace frame 11, the support rod 42, the top support rod 41, the purlin 43, the diagonal brace rod 44, and the reinforcing rod 20 are all hot-dip galvanized steel or aluminum alloy components. The structure is lightweight, convenient for prefabrication and on-site assembly and installation, and can realize modular pre-installation of photovoltaic brackets, shorten the construction cycle. Furthermore, the load-bearing capacity of photovoltaic brackets can be determined in advance through prefabrication technology, enabling photovoltaic brackets to be installed quickly and provide stable support for photovoltaic panels 50.

[0045] In an optional embodiment, the column 12, the cross brace frame 11, the support rod 42, the top support rod 41, the diagonal brace rod 44, and the reinforcing rod 20 can all be rectangular tube rods, which can be prefabricated in the factory and assembled on site. The purlin 43 can be a conventional roof purlin 43 component for photovoltaic panel 50 installation.

[0046] In one or more embodiments, a fence component 30 is provided at the top of the slope 3, and the fence component 30 is connected to several counterweights 2 via cables 40. The fence component 30 can be composed of multiple pile structures. The installation of the pile structure on the top plane of the slope is easier than that on the inclined slope 3. By setting the fence component 30 on the top plane of the slope, it can provide a protective effect for the photovoltaic support, and the connection between the fence component 30 and the counterweights 2 via cables 40 can further stabilize the position of the counterweights 2, improve the pull-out resistance of the counterweights 2, and enable the photovoltaic support to be used stably and safely in complex geological environments.

[0047] This embodiment of a photovoltaic (PV) mounting bracket on a reverse slope achieves the installation of PV panels 50 on a reverse slope through a combination of a support frame 1 and a mounting frame 4. The support frame 1 is fixed by a counterweight 2, which uses its own weight and friction with the slope surface 3 to resist wind and snow loads. This provides a stable support structure for the PV panels 50 without the need for pile foundations or concrete foundation excavation, reducing the cost and difficulty of PV module installation. At the same time, the support frame 1 and the mounting frame 4 can be modularly prepared and assembled on-site, which can effectively improve the efficiency of PV module installation and reduce the cost of PV module installation. In addition, the length of the support rod 42 can be adjusted according to the slope of the slope surface 3 to adapt the PV panels 50 to the reverse slope surface 3, achieving stable installation of the PV panels 50 on the reverse slope and providing more usable locations for PV module installation, which is conducive to the promotion of PV applications.

[0048] Example 2 like Figures 5-6 As shown, a reverse slope photovoltaic system includes a reverse slope photovoltaic bracket as described in Embodiment 1. Several reverse slope photovoltaic brackets are arranged laterally along the slope surface 3, and photovoltaic panels 50 are detachably installed on the top.

[0049] This embodiment of a reverse slope photovoltaic system, by adopting the above-mentioned reverse slope photovoltaic bracket, has high installation efficiency and low cost, can achieve stable installation of photovoltaic panels 50 on the reverse slope, can adapt to stable and safe use in complex geological environments, and has the effects of avoiding ground damage, being eco-friendly, and having controllable costs.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
