When used in small-area installation scenarios such as roofs, photovoltaic panels often use rigid brackets to install and fix photovoltaic panel components.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN201985126U: A solar photovoltaic panel mounting bracket discloses a plurality of beams arranged on the back side of the solar photovoltaic panel, the solar photovoltaic panel is fixedly connected to the beams, the solar photovoltaic panel is mounted above the adjustment support rod with guide grooves, the support beam, and the left beam, the right beam and the bottom beam to form a triangular support frame, the middle of the support beam is hinged with the upper ends of the left beam and the right beam, the beams are fixedly connected to the support beams, the upper end of the adjustment support rod is hinged with the right end of the support beam, and the lower end is connected to the right beam of the triangular support frame through an adjustment seat. The technical solution has the beneficial effects of convenient installation and adjustable angle.

[0004] Although the above utility model patent has adjustable angle and convenient installation, the material cost is high and the stability is poor. Therefore, the field urgently needs a mold-integrated hollow photovoltaic panel bracket to solve the problems existing in the prior art. Utility Model Content

One support mold can support and fix one photovoltaic panel assembly. During on-site installation, all support molds are arranged in an array, and then the photovoltaic panel assemblies are installed on each support mold. A vertical through groove is vertically provided in the middle of the support mold. The design of the vertical through groove can reduce the material cost on the premise of ensuring the stability of the support mold. With the integrated support mold of this solution, each support mold can directly support and fix a whole photovoltaic panel assembly. Compared with the prior art, for supporting a photovoltaic panel assembly, two supports are required to support the opposite sides of the photovoltaic panel assembly respectively. This solution has the following advantages: there is no need to adjust the distance between the two supports. With only one support mold in this solution, it can comprehensively support the edge of the photovoltaic panel assembly, and the existence of the vertical through groove makes the volume of the support mold similar to that of the prior art support, without the disadvantage of high material cost.

[0012] As a preferred solution, the side wall of the support mold is recessed towards the vertical through groove to form an arc-shaped side wall. The arc-shaped side wall can ensure that the support is not prone to rigid deformation during transportation, causing damage to the support.

[0013] As a preferred solution, the second sealing cover is in threaded fit with the ventilation groove.

[0014] As a preferred solution, the support mold is made of polyethylene.

[0015] Beneficial effects:

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0024] As Figure 1 shown, the integrated hollow photovoltaic panel bracket provided in Embodiment 1 of the present invention includes a bracket mold 101 made of polyethylene. The upper surface of the bracket mold 101 is a support inclined plane 102, and the support inclined plane 102 is inclined to the horizontal plane. A photovoltaic panel assembly is installed on the support inclined plane 102. A pouring hole 104 is provided at the top end of the support inclined plane 102, and a clamping structure is provided at the bottom end of the support inclined plane 102. The inside of the bracket mold 101 is filled with air-dried concrete. An expansion bolt is fixedly installed in the area of the air-dried concrete near the pouring hole 104, and a photovoltaic panel pressing block is installed on the top of the expansion bolt. The photovoltaic panel pressing block is fixedly connected to the frame of the photovoltaic panel assembly. On the side of the frame of the photovoltaic panel assembly close to the clamping structure, it is fixedly connected to the clamping structure. One bracket mold 101 can support and fix one photovoltaic panel assembly. During on-site installation, all the bracket molds 101 are arranged in an array, and then the photovoltaic panel assemblies are installed on each bracket mold 101. A vertical through groove 105 is vertically provided in the middle of the bracket mold 101. The design of the vertical through groove 105 can reduce the material cost on the premise of ensuring the stability of the bracket mold 101. With the integrated bracket mold 101 of this solution, each bracket mold 101 can directly support and fix a whole photovoltaic panel assembly. Compared with the prior art, for supporting a photovoltaic panel assembly, the support method that requires two supports to respectively support the opposite sides of the photovoltaic panel assembly, this solution has the advantages: there is no need to adjust the distance between the two supports. With only one bracket mold 101 in this solution, it can comprehensively support the edge of the photovoltaic panel assembly, and the existence of the vertical through groove 105 makes the volume of the bracket mold 101 similar to that of the brackets in the prior art, without the disadvantage of high material cost.

[0025] The clamping structure includes three installation holes 201 opened at the bottom end of the support inclined plane 102. A first sealing cover 202 is detachably and hermetically installed in the installation holes 201. An expansion bolt is fixedly installed in the area of the air-dried concrete near the installation holes 201, and a photovoltaic panel pressing block is installed on the top of the expansion bolt. The photovoltaic panel pressing block is fixedly connected to the frame of the photovoltaic panel assembly.

[0026] At the top of the supporting inclined plane 102, there is an installation plane 103, and the perfusion hole 104 is opened on the installation plane 103.

[0027] On the surface of the supporting inclined plane 102, there is a downwardly sunken wiring groove 107.

[0028] On the bottom surface of the support mold 101, there are two upwardly sunken transport grooves 106. The transport grooves 106 can serve as the force application points for lifting. Inserting a rod-shaped object into the transport grooves 106 makes it easy to lift the support mold 101 filled with concrete, facilitating the adjustment of the layout position of the photovoltaic panels in the later stage.

[0029] The side wall of the support mold 101 is recessed towards the vertical through groove 105, forming an arc-shaped side wall 301. The arc-shaped side wall can ensure that the support is not prone to rigid deformation during transportation, causing damage to the support.

[0030] When using the support, first transport the support mold 101 to the roof or other installation scenarios and arrange the support molds 101 in an array. In the initial state, the first sealing cover 202 plugs the installation hole 201. Then, pour concrete slurry into the support mold 101 from the perfusion hole 104 until it is full. After the concrete slurry dries, remove the first sealing cover 202. Drill holes downward in the concrete at the positions of the perfusion hole 104 and the installation hole 201, and then use expansion bolts to connect and fix the photovoltaic panel pressing blocks. Fix the photovoltaic panel assembly frame to the photovoltaic panel pressing blocks to complete the installation of the photovoltaic panel assembly.

[0031] Such as Figure 2As shown in the figure, the integrated hollow photovoltaic panel support provided by Embodiment 2 of the present utility model includes a support mold 101 made of polyethylene. The upper surface of the support mold 101 is a support inclined plane 102, and the support inclined plane 102 is inclined to the horizontal plane. A photovoltaic panel assembly is installed on the support inclined plane 102. A perfusion hole 104 is provided at the top end of the support inclined plane 102, and a clamping structure is provided at the bottom end of the support inclined plane 102. The inside of the support mold 101 is filled with air-dried concrete. An expansion bolt is fixedly installed in the area of the air-dried concrete near the perfusion hole 104. A photovoltaic panel pressing block is installed on the top of the expansion bolt, and the photovoltaic panel pressing block is fixedly connected to the frame of the photovoltaic panel assembly. On the side of the frame of the photovoltaic panel assembly close to the clamping structure, it is fixedly connected to the clamping structure. One support mold 101 can support and fix one photovoltaic panel assembly. During on-site installation, all the support molds 101 are arranged in an array, and then the photovoltaic panel assemblies are installed on each support mold 101. A vertical through groove 105 is vertically provided in the middle of the support mold 101. The design of the vertical through groove 105 can reduce the material cost on the premise of ensuring the stability of the support mold 101. With the integrated support mold 101 of this solution, each support mold 101 can directly support and fix a whole photovoltaic panel assembly. Compared with the prior art, for supporting a photovoltaic panel assembly, a support method that requires two supports to support the opposite sides of the photovoltaic panel assembly respectively, this solution has the following advantages: there is no need to adjust the distance between the two supports. With only one support mold 101 in this solution, it can comprehensively support the edge of the photovoltaic panel assembly, and the existence of the vertical through groove 105 makes the volume of the support mold 101 similar to that of the support in the prior art, without the disadvantage of high material cost.

[0032] The clamping structure includes a terminal protrusion 401 provided at one end of the support mold 101 away from the perfusion hole 104. A limiting groove 402 is formed between the top of the terminal protrusion 401 and the surface of the support inclined plane 102. The terminal protrusion 401 communicates with the support mold 101. An air vent groove 403 is provided at the top end of the terminal protrusion 401, and a second sealing cover 404 is in threaded fit in the air vent groove 403.

[0033] An installation plane 103 is provided at the top end of the support inclined plane 102, and the perfusion hole 104 is opened on the installation plane 103.

[0034] A wiring groove 107 that is recessed downward is provided on the surface of the support inclined plane 102.

[0035] Two migration grooves 106 that are recessed upward are provided on the bottom surface of the support mold 101. The migration grooves 106 can serve as the force application points for lifting. Inserting a rod-shaped object into the migration grooves 106 is easy to lift the support mold 101 filled with concrete, which is convenient for adjusting the layout position of the photovoltaic panel in the later stage.

[0036] The side wall of the support mold 101 is recessed towards the vertical through groove 105 to form an arc-shaped side wall 301. The arc-shaped side wall can ensure that the support is not easily deformed rigidly during transportation, causing damage to the support.

[0037] When using the support, first move the support mold 101 to the roof or other installation scenarios, arrange the support molds 101 in an array, and then pour concrete slurry into the support mold 101 from the pouring hole 104. When the liquid level reaches the ventilation groove 403, use the second sealing cover 404 to block the ventilation groove 403, and continue to pour concrete slurry until the support mold 101 is full. After the concrete slurry dries, make a hole downward at the pouring hole 104 in the dried concrete, and use expansion bolts to connect and install the photovoltaic panel pressing block. Then, insert one side of the photovoltaic panel assembly into the limiting groove 402 to be limited, so that the photovoltaic panel assembly is supported by the support inclined plane 102, and then fixedly connect the photovoltaic panel pressing block with one end of the photovoltaic panel assembly close to the photovoltaic panel pressing block to complete the installation of the photovoltaic panel assembly. This solution uses the support mold 101 made of concrete and polyethylene as a whole to form a support, which is convenient to install and has a low cost. After the polyethylene is weathered, the concrete can still be preserved, and the service life of the support is more than twenty years.
