[0013] In one embodiment, the photovoltaic support further includes a connector that connects at least two adjacent counterweights arranged in the first preset direction.

[0014] In one embodiment, the counterweight has a first side and a second side opposite to each other along the first preset direction. The first side is provided with a insertion groove, which has an opening that opens away from the second side. The second side is provided with a insertion part, which is adapted to the shape and size of the insertion groove.

[0061] In related technologies, photovoltaic brackets for rooftop photovoltaic systems require drilling holes in the roof for fixing, which has a certain impact on the roof surface.

[0062] To reduce the risk of damage to the roof caused by drilling holes in the roof to fix the photovoltaic bracket, this application proposes a photovoltaic bracket.

[0063] Please refer to the following: Figures 1 to 4 In one embodiment of this application, the photovoltaic support includes a counterweight base 10 and a column assembly 20; the counterweight base 10 includes at least two counterweight groups 11, each of which includes at least two counterweight blocks 100, the at least two counterweight blocks 100 being arranged and connected to each other along a first preset direction; the at least two counterweight groups 11 being arranged side by side along a second preset direction, the second preset direction being at an angle to the first preset direction; one end of the column assembly 20 is connected to the top of the counterweight block 100, and the other end extends upward.

[0064] The counterweight base 10 includes at least two counterweight units 11, for example, it may include two or more counterweight units 11. It should be noted that the number of counterweight units 11 can be flexibly selected according to the volume of the individual counterweight blocks 100 that make up the counterweight unit 11 and the actual construction area. In addition, when there are at least two counterweight units 11, the at least two counterweight units 11 can be arranged at intervals, or they can be spliced ​​together or fully covered.

[0065] The counterweight assembly 11 includes at least two counterweight blocks 100, which can be rectangular, circular, hexagonal, or other shapes. By assembling at least two counterweight blocks 100 along a first preset direction, the volume and weight of the counterweight assembly 11 can be increased, thereby improving the support stability of the counterweight base 10. The counterweight blocks 100 can be cement blocks or metal blocks, as long as they have sufficient load-bearing capacity. When the at least two first counterweight blocks 100 are assembled along the first preset direction, they can be connected by methods such as adhesive, snap-fit, screw connection, or pin connection. The at least two first counterweight blocks 100 can be connected by connecting components, or they can have their own snap-fit ​​or plug-in structures for snap-fit ​​or plug-in connection. When the at least two counterweight blocks 100 are arranged in the first preset direction via connecting components, they can be fitted together or spaced apart.

[0066] In this application, the second preset direction can be perpendicular to the first preset direction, or it can be set at an acute or obtuse angle to the first preset direction. Taking the direction the user faces the photovoltaic panel as a reference, and when the second preset direction is perpendicular to the first preset direction, if the first preset direction is defined as the front-back direction, then the second preset direction can be the left-right direction; if the first preset direction is defined as the left-right direction, then the second preset direction can be the front-back direction.

[0067] The support column assembly 20 is used to directly support the photovoltaic panel assembly. The support column assembly 20 may consist only of an upwardly extending column 21, or it may include an upwardly extending column 21 and a main beam 22 connected to the top of the column 21, thereby jointly supporting the photovoltaic panel assembly through the column 21 and the main beam 22 to improve the support strength of the photovoltaic panel assembly. The connection between the support column assembly 20 and the top of the counterweight block 100 refers to the connection between the support column assembly 20 and the side of the counterweight block 100 opposite to the roof 30. The support column assembly 20 and the counterweight block 100 can be connected by welding, or the support column assembly 20 can be connected to the counterweight block 100 by bolts via column feet 23. It is understood that when the support column assembly 20 and the counterweight block 100 are bolted, the bolts can be pre-installed on the counterweight block 100, i.e., one end of the bolt is located inside the counterweight block 100, and the other end extends out of the top of the counterweight block 100 to connect with the support column assembly 20.

[0068] In the technical solution of this application, a counterweight base 10 is provided. The counterweight base 10 includes several counterweight groups 11, and each counterweight group 11 includes at least two counterweight blocks 100 arranged and connected to each other along a first preset direction. One end of the column is connected to the top of the counterweight block 100, and the other end extends upward. This allows the counterweight base 10 formed by at least two counterweight blocks 100 to stably support the column assembly 20. Furthermore, it allows the column assembly 20 to be directly connected to the counterweight base 10, reducing the risk of the column assembly 20 directly connecting to the roof 30. This makes the photovoltaic bracket adaptable to any roof surface, reducing the risk of roof damage. By providing at least two counterweight groups 11 arranged side-by-side along a second preset direction, the counterweight base 10 occupies a larger space, thereby improving its stability in supporting the column assembly 20 and the photovoltaic panel assembly. Additionally, it can be used to support more photovoltaic panel assemblies, improving power generation efficiency.

[0069] Please see Figure 1 As shown, based on the scheme of having at least two distribution units 11 arranged side by side along the second preset direction, in one example, at least two distribution units 11 are arranged at intervals along the second preset direction; the photovoltaic support also includes a connecting beam assembly 200, the two ends of which are respectively connected to two adjacent distribution units 11.

[0070] When at least two counterweights 11 are spaced apart along a second preset direction, the number of counterweights 100 can be reduced within the same construction area, thereby saving on the cost of the photovoltaic support structure and improving construction efficiency. Additionally, this arrangement reduces the pressure of the counterweights 100 on the roof 30, minimizing damage. Specifically, the connecting beam assembly 200 may include a connecting beam and connecting components for connecting the connecting beam to the counterweights 11. For example, the connecting beam may have a first connecting hole, and the counterweight 11 may have a second connecting hole; bolts are used to connect the connecting beam to the counterweight 11 through the first and second connecting holes. Alternatively, the connecting beam may be connected to the counterweight 11 by screws or snap-fitting using other connecting components.

[0071] By connecting the two ends of the connecting beam assembly 200 to two adjacent sub-assemblies 11 respectively, the two adjacent sub-assemblies 11 can be made into a whole, thereby improving the connection strength between the two adjacent sub-assemblies 11.

[0072] Please refer to the reference. Figure 1 and Figure 5 Furthermore, the connecting beam assembly 200 includes a beam body 210 and a transition piece 220, with one end of the transition piece 220 connected to the beam body 210 and the other end connected to the supporting assembly 11.

[0073] Specifically, the adapter 220 can be connected to the main beam 210 by welding, screw connection, or snap-fit. The adapter 220 can also be connected to the supporting assembly 11 by welding, screw connection, or snap-fit.

[0074] With this configuration, when the connecting beam assembly 200 is damaged, only the beam body 210 or only the adapter 220 can be replaced, thereby reducing the replacement cost of the connecting beam assembly 200.

[0075] Please refer to the reference. Figure 5 and Figure 6 In some embodiments of this application, the adapter 220 includes a fixing part 221 and a card insertion part 222. The fixing part 221 is fixedly connected to the coupling part 11. The card insertion part 222 is connected to the fixing part 221 and is provided with a card slot 222a. The beam body 210 is inserted into the card slot 222a.

[0076] When the fixing part 221 is fixedly connected to the matching part 11, the fixing part 221 and the matching part 11 can be connected by welding or screws. Inserting the beam body 210 into the slot 222a of the insertion part 222 can improve the connection efficiency between the beam body 210 and the adapter 220. Specifically, the fixing part 221 of the adapter 220 can be a plate, an L-shaped bent piece, or a U-shaped bent piece. The insertion part 222 can be a block, and it has insertion slots 101 that can be inserted from both bodies. The shape of the slot 222a can be the same as the outer shape of the beam body 210 or different from the outer shape of the two bodies.

[0077] Furthermore, after the connecting beam is inserted into the insert 222, the two can be welded together to improve the connection stability between the insert 222 and the connecting beam.

[0078] Please refer to the reference. Figure 2 and Figure 3 Based on the scheme of having at least two assemblies 11 arranged side by side along the second preset direction, in another example, at least two assemblies 11 are fitted and spliced ​​together along the second preset direction; the photovoltaic bracket also includes a connecting plate 400, which connects at least two assemblies 11.

[0079] Specifically, only two counterweights 11 can be joined together along the second preset direction, or more than two counterweights 11 can be joined together along the second preset direction. The counterweight 100 can be rectangular, hexagonal, or other shapes. It is understood that when all counterweights 11 are joined together, a full-coverage effect is achieved on the roof 30, thereby improving the stability and support of the counterweight base 10. When the counterweights 100 are hexagonal or rectangular and fully covered on the roof, the gap between adjacent counterweights 100 can be reduced, facilitating a seamless connection. Furthermore, by connecting at least two joined counterweights 11 with the connecting plate 400, the fully covered counterweights 100 form a unified whole, thereby improving the overall stability of the counterweight base 10 and reducing the risk of partial movement of the counterweight base 10.

[0080] Please refer to the reference. Figure 2 and Figure 3 In some embodiments of this application, the photovoltaic bracket further includes a connector 500, which is connected to at least two adjacent counterweights 100 arranged in a first preset direction.

[0081] Specifically, in one example, the connector 500 can connect only two adjacent counterweights 100, so every two adjacent counterweights 100 in each counterweight group 11 can be connected by a connector 500. For example, after two adjacent counterweights 100 are spliced ​​together, they can be connected by inserting pins or screws vertically through them; or, the two ends of the connector 500 can be connected to the top or side surfaces of two adjacent counterweights 100 respectively. In another example, the connector 500 can connect all the counterweights 100 in the same counterweight group 11. The connector 500 can be a connecting rod, which is connected in series through all the counterweights 100 in the same counterweight group 11. The two ends of the connecting rod can be secured with nuts or bent to reduce the risk of the counterweights 100 protruding from the ends of the connecting rod. The connector 500 can also be a strip plate that is connected to the top surface of all the counterweights 100 in the same counterweight group 11, or the strip plate is connected to the side or bottom surface of all the counterweights 100 in the same counterweight group 11, etc.

[0082] By connecting at least two adjacent counterweights 100 arranged in the first preset direction through connector 500, the connection strength between two adjacent counterweights 100 in each counterweight group 11 can be improved, the risk of mutual movement between two adjacent counterweights 100 can be reduced, and thus the stability of supporting photovoltaic panel modules can be improved.

[0083] Please refer to the reference. Figures 7 to 10 In some embodiments of this application, the counterweight 100 has a first side and a second side opposite to each other along a first preset direction. The first side is provided with a plug groove 101, which has an opening that opens away from the second side. The second side is provided with a plug portion 102, which is adapted to the shape and size of the plug groove 101. The plug portion 102 of one of two adjacent counterweights 100 can be inserted into the opening of the other one.

[0084] This configuration allows two adjacent counterweights 100 to be inserted into each other in the first preset direction, thereby achieving the effect that at least two counterweights 100 can be arranged and connected in the first preset direction, and reducing the need for the user to lift the counterweights 100 to assemble and connect them.

[0085] Specifically, the insertion part 102 can be an insertion block or an insertion post, etc. The shape and size of the insertion slot 101 are adapted to the insertion part 102, meaning that the insertion part 102 can be inserted precisely into the insertion slot 101, thereby achieving a good insertion effect. Furthermore, in order to achieve a better connection between two adjacent counterweights 100, the two adjacent counterweights 100 can be connected by other connecting components, such as pins or screws.

[0086] Please refer to the reference. Figure 7 and Figure 8 In one example, the counterweight 100 includes a main body 110 and an overlapping plate 120. The main body 110 has a first surface and a second surface opposite to each other along a first preset direction. There are two overlapping plates 120, which are respectively disposed on the first surface and the second surface, and are centrally symmetrical about the center of the main body 110. One overlapping plate 120 and the main body 110 together form an insertion groove 101, and the other overlapping plate 120 forms an insertion part 102.

[0087] This arrangement allows the space formed by the overlapping plate 120 on the first side and the main body 110 to serve as an insertion slot 101, enabling the overlapping plate 120 on the second side of adjacent counterweights 100 to be inserted into this slot 101. The overlapping plates 120 on the first and second sides can overlap vertically, facilitating subsequent connection to the overlapping plates 120 using connecting pins or bolts, thus ensuring a more stable connection between adjacent counterweights 100. Furthermore, by centrally symmetrically arranging the overlapping plates 120 on the first and second sides of the same counterweight 100 about the center of the main body 110, the counterweights 100 can be inserted into each other regardless of whether they are placed upright or upside down during arrangement, thereby improving the efficiency and reducing the error rate of counterweight installation. Additionally, this arrangement facilitates seamless splicing when adjacent counterweights 100 are joined together.

[0088] Please refer to the reference. Figure 9 and Figure 10 In another example, the counterweight 100 includes a main body 110 and a first extension plate 130. The main body 110 has a first surface and a second surface opposite to each other along a first preset direction. The first extension plate 130 is connected to the first surface and is provided at intervals in the vertical direction. The two first extension plates 130 and the first surface together form an insertion groove 101. The insertion part 102 is provided on the second surface.

[0089] By providing two first extension plates 130 spaced vertically on the first surface of the main body 110 of the counterweight 100, the two first extension plates 130 and the first surface together form a plug-in groove 101 structure with the insertion port facing a first preset direction. At this time, the insertion portion 102 on the second surface of adjacent counterweights 100 can be inserted into the plug-in groove 101 in the first preset direction, thereby achieving the effect of interlocking adjacent counterweights 100 along the first preset direction. Furthermore, by providing two first extension plates 130, the two first extension plates 130 can respectively limit the upward and downward directions of the counterweight 100, thus providing better insertion stability.

[0090] Please refer to the reference. Figure 11 and Figure 12 In some embodiments of this application, the counterweight 100 includes a main body 110 and an adapter 140. The main body 110 has a first surface and a second surface opposite to each other along a first preset direction. Two adapters 140 are provided, which are respectively located on the first surface and the second surface and are centrally symmetrical about the center of the main body 110. The adapter 140 includes a second extension plate 141 and a plug-in plate 142. The second extension plate 141 is connected to the main body 110. The plug-in plate 142 is connected to the extension plate at an angle, and a slot 140a is formed between the plug-in plate 142 and the main body 110. The plug-in plate 142 of one of two adjacent counterweights 100 can be inserted into the slot 140a of the other.

[0091] With this configuration, the second extension plate 141 of the adapter 140, the plug plate 142 of the adapter 140, and the main body 110 connecting the second extension plate 141 together form a slot 140a structure that can face upward or downward. By providing adapters 140 on the first and second surfaces of the main body 110, and arranging the two adapters 140 symmetrically about the center of the main body 110, when the insertion plate 142 on the first surface of the main body 110 faces upward, the slot 140a of the adapter 140 on the first surface also faces upward. Simultaneously, the insertion plate 142 on the second surface of the main body 110 faces downward, and the slot 140a of the adapter 140 on the second surface also faces downward. Therefore, when the first surface of one of two adjacent counterweights 100 faces the second surface of the other, the insertion plate 142 of the adapter 140 of one can be inserted vertically into the slot 140a of the other, thus achieving a vertical interlocking effect between the two adjacent counterweights 100. This facilitates adaptation to scenarios with limited operating space in the first preset direction. Furthermore, this arrangement also facilitates seamless splicing when two adjacent counterweights 100 are joined together.

[0092] Please refer to the reference. Figure 13 and Figure 14 In some embodiments of this application, the counterweight 100 includes a main body 110 and a protrusion 150. The main body 110 has a first surface and a second surface opposite to each other along a first preset direction. The main body 110 also has a central vertical surface perpendicular to the first preset direction. Two protrusions 150 are provided, and the two protrusions 150 are respectively provided on the first surface and the second surface, and are symmetrically arranged about the central vertical surface. The protrusions 150 of each counterweight 100 overlap with the protrusions 150 of the adjacent counterweight 100 in the vertical direction.

[0093] Specifically, when two protrusions 150 are provided, each protrusion 150 can be block-shaped or plate-shaped. By providing protrusions 150 on both the first and second surfaces, and symmetrically arranging the protrusions 150 about the central vertical plane of the main body 110, the protrusions 150 of each counterweight 100 overlap with the protrusions 150 of adjacent counterweights 100 in the vertical direction. This allows adjacent counterweights 100 to interlock and cooperate, while also simplifying the structure of the counterweights 100. Furthermore, this arrangement allows for the connection of the two overlapping protrusions 150 of adjacent counterweights 100 by inserting connecting pins or bolts through them, achieving a good and stable connection between the two counterweights 100. Additionally, this arrangement facilitates seamless splicing when adjacent counterweights 100 are joined together.

[0094] This application also proposes a photovoltaic system, which includes a photovoltaic panel assembly and a photovoltaic support frame. The specific structure of the photovoltaic support frame is as described in the above embodiments. Since this photovoltaic system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The photovoltaic panel assembly is installed at the end of the column assembly 20 away from the counterweight base 10.
