Detailed Description
The utility model is described in further detail below with reference to fig. 2-3.
The embodiment of the utility model discloses an anti-loosening photovoltaic panel pressing block. Referring to fig. 2, the anti-loosening photovoltaic panel pressing block includes a pressing member 2 abutting against a photovoltaic panel 1, a base 3 connected to a guide rail 9, and a vibration damping pad 4 provided on the pressing member 2. The vibration absorbing pad 4 is abutted against the photovoltaic panel 1 and used for absorbing the energy of vibration of the photovoltaic panel 1, so that vibration of the pressing block is reduced.
The compressing element 2 and the base 3 are integrally formed, the base 3 is provided with a first through hole 6, and the bolt 5 penetrates through the first through hole 6 to fixedly connect the pressing block with the guide rail 9 on the bracket. After the pressing block is abutted against the side frame of the photovoltaic panel 1 by a worker, the bolt 5 is screwed by the worker through a special tool, so that the photovoltaic panel 1 is fixedly mounted on the support.
Referring to fig. 2, the pressing member 2 includes a first side plate 21 and a second side plate 22 disposed perpendicular to each other. The first side plate 21 abuts against the side wall of the photovoltaic panel 1, and the second side plate 22 abuts against the top wall of the photovoltaic panel 1, thereby fixing the position of the photovoltaic panel 1.
The vibration damping pad 4 is disposed on the first side plate 21, and the vibration damping pad 4 abuts against the side wall of the photovoltaic panel 1. When the photovoltaic panel 1 vibrates at a high frequency with a low amplitude under the action of wind load, the vibration damping pad 4 is used for absorbing the vibration energy of the photovoltaic panel 1 and reducing the vibration energy received by the pressing block, so that the vibration of the pressing block is reduced. The occurrence of loosening of the bolts 5 connected between the press block and the guide rail 9 due to vibration of the press block is minimized. Thereby strengthen the fixed action of briquetting to photovoltaic board 1, reduce the condition emergence that takes place not hard up between briquetting and the photovoltaic board 1.
Referring to fig. 2 and 3, a mounting groove 7 is formed in a side of the first side plate 21 adjacent to the photovoltaic panel 1, and the mounting groove 7 is used for placing the vibration-damping pad 4 so as to strengthen the connection between the vibration-damping pad 4 and the pressing member 2. Meanwhile, the groove side wall of the mounting groove 7 is provided with a limit groove 8 so as to further improve the connection strength between the vibration reduction pad 4 and the compression piece 2.
Referring to fig. 3, the vibration damping pad 4 includes a viscoelastic member 41 and a rigid member 42 disposed at a distance.
The viscoelastic member 41 is made of a viscoelastic material such as a high molecular polymer of neoprene, silicone rubber, polyvinyl chloride, epoxy resin, and foam. The viscoelastic material has a certain damping, and can convert the energy of vibration into heat for dissipation. In this embodiment, the viscoelastic member 41 is made of neoprene.
The rigid member 42 is a metal sheet, and may be made of copper, iron, or the like. When the photovoltaic panel 1 vibrates, the viscoelastic material in the vibration damping pad 4 does not act simultaneously due to factors such as installation, uncertainty of the photovoltaic vibration, and the like. For example, the viscoelastic member 41 having a smaller degree of compression with the photovoltaic panel 1 plays a smaller role, whereas the viscoelastic member 41 having a larger degree of compression with the photovoltaic panel 1 plays a larger role.
By arranging the metal sheets on both sides of the viscoelastic member 41, when the viscoelastic member 41 in a certain portion is subjected to a large vibration, the viscoelastic member 41 absorbs a part of the energy and transmits the rest of the energy to the metal sheets; after the metal sheet bends and vibrates to absorb a part of energy, other energy is transmitted to other parts of the viscoelastic member 41 through the metal sheet, and further functions of other parts of the viscoelastic member 41 are exerted.
Namely, the vibration-damping pad 4 further improves the vibration-damping effect of the vibration-damping pad 4 by combining the two modes of the viscoelastic piece 41 and the rigid piece 42 which are arranged at intervals, namely, energy absorption and vibration damping by using the material of the viscoelastic piece 41 and the structure bending of the rigid piece 42, thereby reducing the looseness of the pressing block and the photovoltaic panel 1 caused by vibration.
The above embodiments are not intended to limit the scope of the present utility model, so: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
