[0051] Embodiment 1

[0052] like Figure 1 As shown, this embodiment provides a photovoltaic system. The photovoltaic system provided in this embodiment includes a photovoltaic component 20 and a photovoltaic bracket 10. The photovoltaic bracket 10 is used to support and fix the photovoltaic component 20.

[0053] Existing photovoltaic brackets usually use a pressing block to press and fix the photovoltaic assembly 20 on the bracket beam, so that there is a certain gap between the photovoltaic assemblies 20. In the actual application scenario of the photovoltaic system, the entire photovoltaic bracket that installs and fixes the photovoltaic assembly 20 needs to have a certain waterproof function to meet the customer's installation requirements. Therefore, it is necessary to install a water tank in the gap between adjacent photovoltaic assemblies 20, so that the water falling on the photovoltaic assembly 20 can be collected through the water tank and the collected water can be discharged to achieve the waterproof function of the photovoltaic bracket. However, the water tank and the photovoltaic assembly 20 are not installed closely, and there is a certain height difference and gap between the water tank and the photovoltaic assembly 20. When encountering heavy rain weather, due to the large water flow, water is easy to splash or overflow from the water tank. In addition, the photovoltaic bracket needs to install multiple water tanks, which makes the structure complicated, greatly increases the difficulty of installation and construction, reduces the efficiency of installation, and also increases the construction cost.

[0054] In order to solve the above problems, Figure 1 to Figure 5 As shown, the photovoltaic bracket 10 provided in this embodiment includes a column 3, an installation component 2 and a plurality of connection components 1, wherein a column 3 is arranged below part of the connection components 1, the installation component 2 includes a plurality of main beams 21, the adjacent main beams 21 are sealed and spliced ​​by the connection components 1, and the two opposite sides of each main beam 21 are provided with a sealed connection groove 215, and the sealed connection groove 215 is used to seal and connect the frame 201 of the photovoltaic component 20 on the corresponding side. The photovoltaic bracket 10 provided in this embodiment seals and connects the frame 201 of the photovoltaic component 20 on the corresponding side through the sealed connection groove 215 on the main beam 21, and seals and splices the adjacent main beams 21 through the connection component 1, and supports and fixes part of the connection component 1 through the column 3, so that the photovoltaic bracket 10 not only realizes the fixed support of the photovoltaic component 20, but also has a good waterproof function, and the photovoltaic bracket 10 does not need to install additional structural parts such as a water tank, so that the structure is simple, easy to construct and install, improves the installation efficiency, and greatly reduces the construction cost. In addition, since each main beam 21 is provided with sealing connection grooves 215 on both sides opposite to each other to seal and connect the frame 201 of the photovoltaic assembly 20 on the corresponding side, the structure is compact and the cost is further reduced.

[0055] It should be noted that, in order to facilitate the photovoltaic assembly 20 to be exposed to light for a long time, the entire photovoltaic bracket 10 is tilted, so the rainwater received by the photovoltaic bracket 10 can flow down from the edge of the lowest end of the photovoltaic bracket 10. In addition, since the columns 3 are arranged below some of the connecting components 1, the columns 3 can be arranged at a certain distance to support the photovoltaic assembly 20, and the photovoltaic assembly 20 can be stably supported on the basis of ensuring the cost. It should be noted that the specific number of columns 3 can be adjusted according to the size of the photovoltaic bracket 10 and the support stability.

[0056] It should be noted that, in this embodiment, Figure 1 As shown, each photovoltaic module 20 is provided with main beams 21 around it, and two adjacent photovoltaic modules 20 share a main beam 21 on the corresponding side, so that the main beam 21 can be used as a sealing and waterproof part and also as a purlin for installation.

[0057] In this embodiment, if Figure 4 and Figure 5 As shown, the main beam 21 includes a top plate 211, a vertical plate 212 and a bottom plate 213 connected at an angle in sequence, wherein the top plate 211 and the bottom plate 213 are arranged in parallel and spaced relative to each other in the up-down direction, and the top plate 211, the vertical plate 212 and the bottom plate 213 are jointly surrounded to form a sealing connection groove 215, and a waterproof adhesive strip 2111 is provided on the side of the top plate 211 facing the bottom plate 213, and the waterproof adhesive strip 2111 is used to abut against the upper end of the frame 201. Specifically, when the frame 201 is inserted into the sealing connection groove 215, the upper end of the frame 201 just abuts against the waterproof adhesive strip 2111, so that the sealing connection groove 215 realizes the sealing, wrapping and fixing of the frame 201. In addition, by providing the waterproof adhesive strip 2111, the sealing connection effect of the sealing connection groove 215 on the frame 201 is further improved, and the waterproof effect of the entire photovoltaic bracket 10 is improved. It should be noted that, in this embodiment, the two sealing connection grooves 215 on the opposite sides of the main beam 21 can share the top plate 211, the vertical plate 212 and the bottom plate 213, so that the top end of the vertical plate 212 is connected to the middle of the top plate 211, and the bottom end of the vertical plate 212 is connected to the middle of the bottom plate 213, making the structural design of the main beam 21 more compact and reasonable.

[0058] Optionally, in this embodiment, if Figure 5 As shown, the top plate 211 can be in the form of a flat plate. In other embodiments, the top plate 211 can also be in the form of an arc plate, which is more convenient for rainwater to slide down on the top plate 211 and avoid the infiltration of rainwater.

[0059] Optionally, in this embodiment, if Figure 4 and Figure 5As shown, the main beam 21 also includes a limit plate 214, which is connected to the top plate 211 at an angle, and the vertical plate 212, the top plate 211 and the limit plate 214 are jointly surrounded to form a clamping groove 216 connected to the sealing connection groove 215, and the clamping groove 216 is used to clamp the convex strip 2011 protruding from the upper end of the edge of the frame 201. It should be noted that in this embodiment, the convex strip 2011 is abutted against the waterproof rubber strip 2111. The above arrangement enables the convex strip 2011 to be inserted into the clamping groove 216 and abut against the waterproof rubber strip 2111 when the frame 201 is inserted into the sealing connection groove 215, further improving the stability of the frame 201 being plugged and fixed in the sealing connection groove 215. In addition, it should be noted that when assembling the photovoltaic module 20 with the main beam 21, the photovoltaic module 20 needs to be tilted at a certain angle first, so that the convex strip 2011 of the frame 201 is inserted into the snap-in groove 216, and the convex strip 2011 is abutted against the waterproof rubber strip 2111 at the top during the insertion, and then the photovoltaic module 20 is placed flat, so that the plug-in cooperation between the convex strip 2011 and the snap-in groove 216 realizes the positioning and installation of the frame 201 in the sealing connection groove 215, making the installation more convenient and reliable. Optionally, in this embodiment, the limit plate 214 is connected to the top plate 211 at an angle of 90°, so that the limit plate 214 and the vertical plate 212 are arranged in parallel and spaced relation.

[0060] Optionally, in this embodiment, if Figure 4 and Figure 5 As shown, abutting protrusions 2131 are convexly provided on one side of the bottom plate 213 facing the top plate 211. When the frame 201 is inserted into the sealing connection groove 215, the abutting protrusions 2131 abut against the lower end of the frame 201. By setting the abutting protrusions 2131 to abut against the lower end of the frame 201, the tightness of the abutment between the convex strip 2011 and the waterproof rubber strip 2111 is ensured, and the sealing connection effect of the sealing connection groove 215 on the frame 201 is further improved. Optionally, in other embodiments, the abutting protrusions 2131 can also be directly inserted into the groove at the lower end of the frame 201.

[0061] In this embodiment, if Figure 1 and Figure 6 As shown, a plurality of docking grooves 131 are arranged at intervals on the outer periphery of the connection assembly 1, and the docking grooves 131 are used to seal and connect with the ends of the main beam 21 on the corresponding side. By providing the docking grooves 131, a sealed connection with the ends of the main beam 21 on the corresponding side is achieved, which effectively ensures the tightness and sealing of the connection and fixation between the connection assembly 1 and the main beam 21.

[0062] In this embodiment, the connection assembly 1 includes a first plate 11, a second plate 12 and a connection plate 13, wherein four first avoidance grooves 111 are evenly spaced on the periphery of the first plate 11, the second plate 12 is located below the first plate 11 and directly opposite to the first plate 11, and four second avoidance grooves 121 are evenly spaced on the periphery of the second plate 12, the first avoidance grooves 111 and the second avoidance grooves 121 are used to avoid and accommodate the corners of the photovoltaic components 20 on the corresponding side, and the connection plate 13 is cross-shaped, the connection plate 13 is connected between the first plate 11 and the second plate 12, and the periphery of the connection plate 13, the first plate 11 and the second plate 12 are jointly surrounded to form four evenly spaced docking grooves 131. The above arrangement makes the first plate 11, the second plate 12 and the connection plate 13 all in the form of cross-shaped plates, so that the splicing between the photovoltaic components 20 and the connection assembly 1 is tighter, and the waterproof effect of the photovoltaic bracket 10 is better guaranteed. Specifically, the docking groove 131 is staggered at 45° with the first avoidance groove 111 and the second avoidance groove 121 which are opposite to each other up and down, and the docking groove 131, the first avoidance groove 111 and the second avoidance groove 121 are all right-angle grooves at 90°, and both ends of the main beam 21 are 90° sharp-angle protruding structures. When the main beam 21 with the photovoltaic component 20 fixed is connected to the connecting component 1, the sharp-angle protruding structure at the end of the main beam 21 is inserted into the docking groove 131 and fixed, and the corners of the photovoltaic component 20 (referring to the corners of the main part of the photovoltaic component 20) are just located in the first avoidance groove 111 and the second avoidance groove 121, so that the main beam 21, the connecting component 1 and the photovoltaic component 20 are more tightly spliced ​​together.

[0063] Optionally, in this embodiment, if Figure 4 and Figure 6 As shown, four first mounting holes 122 are provided on the second plate 12 along its circumferential direction, and a second mounting hole 2132 is provided on the bottom plate 213 at the end of the main beam 21. When the pointed protrusion structure at the end of the main beam 21 is inserted into the docking groove 131, bolts can be screwed through the corresponding first mounting holes 122 and second mounting holes 2132 in sequence, thereby achieving a firm fixation of the pointed protrusion structure in the docking groove 131.

[0064] Optionally, in this embodiment, a waterproof film (not shown) is provided on the groove wall of the docking groove 131, and the waterproof film is sandwiched between the groove wall of the docking groove 131 and the end of the main beam 21. By providing the waterproof film, the sealing performance of the sharp-angle protruding structure at the end of the main beam 21 connected in the docking groove 131 is further improved.

[0065] In this embodiment, if Figure 7 As shown, the column 3 includes a column body 31 and a connecting cross plate 32 . The connecting cross plate 32 is connected to the top of the column body 31 , and the connecting cross plate 32 is fixedly connected to the connecting component 1 , thereby supporting and fixing the connecting component 1 .

[0066] Optionally, in this embodiment, the column 3 includes four connecting transverse plates 32, and the four connecting transverse plates 32 are all connected to the top of the column body 31. The four connecting transverse plates 32 are evenly spaced along the outer circumference of the column body 31, and each connecting transverse plate 32 is provided with a third mounting hole 321. At the bottom of the connecting component 1 where the column 3 is provided, a bolt can be screwed through the corresponding third mounting hole 321, the first mounting hole 122 and the second mounting hole 2132 in sequence, thereby realizing the fixed connection between the column 3, the connecting component 1 and the main beam 21.

[0067] The photovoltaic system provided in this embodiment uses the above-mentioned photovoltaic bracket 10 to support and fix the photovoltaic component 20, so that the photovoltaic bracket 10 not only realizes the fixed support of the photovoltaic component 20, but also has a good waterproof function, and the photovoltaic bracket 10 does not need to install additional structural parts such as a water tank, so that the structure is simple and easy to construct and install, which improves the installation efficiency, greatly reduces the construction cost, and makes the structure compact, further reducing the cost.

[0068] Embodiment 2

[0069] The photovoltaic bracket 10 provided in this embodiment is substantially the same as that in the first embodiment. The photovoltaic bracket 10 provided in this embodiment is different from that in the first embodiment in that:

[0070] like Figure 8 to Figure 13 As shown, the installation assembly 2 provided in this embodiment also includes a connection anchor 22, and the connection anchor 22 includes a flexible connection belt 221 and a clamping block 222 connected to each other. The flexible connection belt 221 is arranged at the upper end of the frame 201, and a mounting groove 2112 is provided on the top plate 211. The clamping block 222 can be clamped and fixed in the mounting groove 2112. The main beam 21 and the photovoltaic assembly 20 are installed and fixed by setting the connection anchor 22, which effectively improves the stability of the installation and fixation of the main beam 21 and the photovoltaic assembly 20. Specifically, when the photovoltaic module 20 is assembled with the main beam 21, it is necessary to first insert the clamping block 222 of the connecting anchor 22 at the upper end of the frame 201 into the installation groove 2112 from above the top plate 211. Since the flexible connecting belt 221 is a flexible and bendable structure, the upper end of the frame 201 can be pressed against the waterproof rubber strip 2111. Then, the photovoltaic module 20 is rotated downward so that the photovoltaic module 20 is placed flat. At this time, the frame 201 can be inserted into the sealing connection groove 215, and the length of the flexible connecting belt 221 is just enough to allow the frame 201 to be inserted into the sealing connection groove 215, and the upper end of the frame 201 is pressed against the waterproof rubber strip 2111. The mutual cooperation between the connecting anchor 22 and the waterproof rubber strip 2111 not only ensures the sealed connection of the frame 201 in the sealing connection groove 215, making installation convenient, but also ensures the stability of the frame 201 in the sealing connection groove 215.

[0071] Optionally, in this embodiment, if Fig. 9 As shown, when the frame 201 is inserted into the sealing connection groove 215, the abutment protrusion 2131 on the bottom plate 213 is inserted into the positioning groove 202 at the lower end of the frame 201, thereby making the connection of the frame 201 in the sealing connection groove 215 more stable.

[0072] Optionally, in this embodiment, a plurality of connecting anchors 22 are arranged at intervals on the upper end of the frame 201 along the extension direction of the frame 201, and a plurality of mounting grooves 2112 are arranged on the top plate 211 along the extension direction of the top plate 211. The number of the mounting grooves 2112 is twice the number of the connecting anchors 22, so that the two frame frames 201 on both sides of the main beam 21 can be connected to the same top plate 211, and the stability of the connection between the frame 201 and the main beam 21 along its length direction is ensured.

[0073] Optionally, in this embodiment, if Fig. 9 As shown, the top plate 211 is a curved plate, which makes it easier for rainwater to slide down the top plate 211 and avoids the infiltration of rainwater.

[0074] In this embodiment, if Fig.10 , Fig.12 and Fig.13 As shown, the mounting slot 2112 includes a first slot 21121 and a second slot 21122 that are connected to each other, the second slot 21122 is arranged adjacent to the first slot 21121, the cavity below the first slot 21121 is the first cavity 21123, the cavity below the second slot 21122 is the second cavity 21124, the first cavity 21123 and the second cavity 21124 are connected, the size of the first slot 21121 is larger than the size of the snap-in block 222 and the flexible connecting belt 221, the size of the second slot 21122 is larger than the size of the flexible connecting belt 221 and smaller than the size of the snap-in block 222, and the snap-in block 222 can move between the first cavity 21123 and the second cavity 21124. The above arrangement enables the first notch 21121 and the second notch 21122 to allow the flexible connection belt 221 to penetrate, and the clamping block 222 can pass through the first notch 21121 into the first cavity 21123, and after the clamping block 222 is moved from the first cavity 21123 to the second cavity 21124, the flexible connection belt 221 is pulled at this time, and the clamping block 222 will not be disengaged from the second notch 21122 to the mounting groove 2112, which effectively ensures the stability of the clamping block 222 in the mounting groove 2112. It should be noted that when the clamping block 222 needs to be disengaged from the mounting groove 2112, the clamping block 222 is moved from the second cavity 21124 to the first cavity 21123, and then the flexible connection belt 221 is pulled, and the clamping block 222 can be disengaged from the mounting groove 2112 from the first notch 21121.

[0075] Optionally, in this embodiment, if Fig.12 and Fig.13 As shown, a limit block 2113 protrudes downward on the inner top wall of the mounting groove 2112. When the clamping block 222 abuts against the inner top wall of the mounting groove 2112 in the second cavity 21124, the limit block 2113 can abut against the clamping block 222 to limit the movement of the clamping block 222 toward the first cavity 21123, thereby preventing the clamping block 222 from moving from the second cavity 21124 to the first cavity 21123 along the inner top wall of the mounting groove 2112 under the action of a pulling force, and escaping from the mounting groove 2112 through the first notch 21121, further ensuring the stability and reliability of the clamping block 222 in the mounting groove 2112. It should be noted that when the snap-in block 222 needs to be removed from the mounting groove 2112, the pulling force on the flexible connecting belt 221 is first removed so that the snap-in block 222 moves in the direction away from the inner top wall of the mounting groove 2112, so that the snap-in block 222 is separated from the abutment with the top wall of the mounting groove 2112, so that the snap-in block 222 will not be blocked by the abutment of the limit block 2113 during the process of moving from the second cavity 21124 to the first cavity 21123, so that the snap-in block 222 can slide from the second cavity 21124 to the first cavity 21123, and then the flexible connecting belt 221 is pulled so that the snap-in block 222 can be removed from the first slot 21121 and out of the mounting groove 2112.
