[0002] A solar photovoltaic bracket is a special bracket designed for placing, installing, and fixing solar panels in a solar photovoltaic power generation system. The structure of a solar photovoltaic bracket mainly consists of a lighting bracket unit, an angle adjustment unit, and a support unit. The lighting bracket unit is the basic bracket structure for carrying photovoltaic modules; the angle adjustment unit includes 2 angle tracking and adjustment unit modules, which are driven by electric cylinders to perform sun altitude angle tracking and adjustment, and use a worm and worm gear transmission mechanism for sun azimuth angle tracking; the support unit mainly consists of 1 support pipe and 2 flange plates, and has the characteristics of good load-bearing performance and small volume.

[0003] In addition, the solar photovoltaic bracket also includes a main bracket assembly, a connecting piece, a guide rail and a beam, a pressing block and a fixture, a fixing fitting, and other auxiliary fittings. Among them, the main bracket assembly uses C-shaped / U-shaped steel as the main frame, and is fixed by a number of fixing bolts, so that the overall solar photovoltaic bracket has high load-bearing capacity and excellent mechanical properties.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] To enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] As Figures 1 to 6 shown, a fixing device for a U-shaped steel bracket in an embodiment of the present utility model includes a bolt 1 and a protection mechanism 2.

[0033] Among them, a gasket 101 is connected to the bolt 1. The bolt 1 can better fix the U-shaped steel bracket through the gasket 101 to ensure the firmness of the U-shaped steel bracket during installation.

[0034] In addition, an installation groove 102 is provided at the top of the bolt 1 for the insertion of the insertion block 204 to fix the protection mechanism 2, and the protection mechanism 2 is used to protect the bolt 1 to reduce the influence of rain on the bolt 1.

[0035] Specifically, a pair of threaded grooves 103 are symmetrically drilled on the bolt 1. The threaded grooves 103 are communicated with the installation groove 102, and the threaded grooves 103 are used to accommodate the screw 104.

[0036] As Figures 1 to 6 shown, a clamping mechanism is installed in the installation groove 102. The clamping mechanism can be used to fix the protection mechanism 2 so that the protection mechanism 2 can stably protect the bolt 1.

[0037] Among them, the clamping mechanism includes a pair of screws 104, and the pair of screws 104 are respectively threadedly connected in the pair of threaded grooves 103. The screw 104 is used to connect the arc-shaped shell 106 and the fixing bead 107. In addition, by threading the screw 104 into the threaded groove 103, it is convenient to replace the arc-shaped shell 106 and the fixing bead 107.

[0038] In addition, a connecting rod 105 is fixedly connected to the screw 104. One end of the connecting rod 105 away from the screw 104 is connected to the arc-shaped shell 106, and the arc-shaped shell 106 is used to install the fixing bead 107. The fixing bead 107 is rotatably connected in the arc-shaped shell 106. By clamping the fixing bead 107 in the annular card slot, the fixation of the protection mechanism 2 can be realized, so that the protection mechanism 2 can be used to protect the bolt 1, making the bolt 1 not easily corroded by rainwater. This can not only improve the service life of the bolt 1, but also ensure the firmness of the fixation of the U-shaped steel bracket.

[0039] As Figures 1 to 6As shown, the protection mechanism 2 is arranged outside the bolt 1. The protection mechanism 2 is used to protect the bolt 1 so that the bolt 1 is not easily affected by rainwater, which can not only ensure the service life of the bolt 1, but also ensure the firmness of the U-shaped steel support fixation.

[0040] Among them, the protection mechanism 2 includes a top cover 201, and the top cover 201 is connected to the engaging mechanism. The diameter of the top cover 201 is larger than the diameter of the gasket 101 and smaller than the outer diameter of the contact part 203.

[0041] In addition, a telescopic part 202 is connected to the top cover 201. The telescopic part 202 can be telescoped so that the whole protection mechanism 2 can be applicable to bolts 1 of different lengths, expanding the application range of the protection mechanism 2.

[0042] Specifically, a contact part 203 is connected to the telescopic part 202. The contact part 203 can increase the contact effect between the telescopic part 202 and the U-shaped steel support, so that rainwater is not easily leaked from the gap between the telescopic part 202 and the U-shaped steel support, to ensure the protection effect of the protection mechanism 2 on the bolt 1.

[0043] In addition, a counterweight ring 2031 is embedded in the contact part 203, and the counterweight ring 2031 is made of metal material. When the U-shaped steel support is fixed by the bolt 1, that is Figure 6 the state shown, the counterweight ring 2031 is used to increase the counterweight of the contact part 203 so that the telescopic part 202 can be unfolded, so that the contact part 203 can contact the U-shaped steel support, so as to use the protection mechanism 2 to protect the bolt 1.

[0044] As Figures 1 to 6 shown, an insertion block 204 is connected to the inner bottom of the top cover 201, and the insertion block 204 is inserted into the installation groove 102. By inserting the insertion block 204 into the installation groove 102, the fixation of the protection mechanism 2 can be realized, so that the protection mechanism 2 can stably protect the bolt 1.

[0045] Among them, an annular card slot is provided on the side wall of the insertion block 204, and the fixed bead 107 corresponds to the annular card slot. By engaging the fixed bead 107 in the annular card slot, the fixation of the protection mechanism 2 can be realized, which is convenient for operation.

[0046] Optionally, the telescopic part 202, the contact part 203 and the insertion block 204 are all made of elastic material, which can improve the service life of the telescopic part 202, the contact part 203 and the insertion block 204, to ensure the protection effect of the protection mechanism 2 on the bolt 1.

[0047] Preferably, the telescopic part 202, the contact part 203 and the insertion block 204 are all made of rubber material. The telescopic part 202 and the contact part 203 can be integrally formed or bonded by glue.

[0048] During specific use, the U-shaped steel support is fixed through the mutual cooperation of the bolt 1 and the gasket 101, that is Figure 6 the state shown.

[0049] A pair of screw rods 104 are respectively threadedly installed in a pair of threaded grooves 103. At this time, some fixing beads 107 will protrude and enter the installation groove 102. The insertion block 204 is inserted into the installation groove 102. Since the insertion block 204 is made of rubber, the fixing beads 107 will be clamped in the annular card slot on the side wall of the insertion block 204, that is Figure 4 the state shown, and thus the fixation of the protection mechanism 2 can be realized.

[0050] Since a counterweight ring 2031 is installed in the contact part 203, the counterweight ring 2031 can increase the counterweight of the contact part 203, so that the telescopic part 202 can be unfolded, and at the same time, the contact part 203 can be in contact with the U-shaped steel support, so as to use the protection mechanism 2 to protect the bolt 1, reduce the corrosion of the bolt 1 by rainwater, not only ensure the service life of the bolt 1, but also ensure the firmness of the fixation of the U-shaped steel support.
