A photovoltaic power generation solar panel support

Abstract

The present invention discloses a support for a photovoltaic power generation solar panel, which includes a mounting bracket. The mounting bracket includes a telescopic frame, two support frames disposed outside the telescopic frame, and a telescopic rod hinged to the tops of the two support frames; a cross beam for carrying the photovoltaic power generation solar panel, the cross beam is hinged to the top of the telescopic frame, and both of the two telescopic rods are hinged under the cross beam. The telescopic rod at the lower end of the cross beam is a hydraulic telescopic rod that requires continuous pressure supply. In the present invention, during the use of this bracket, when encountering strong winds, the baffle is lifted by the wind, allowing the wind to enter the air inlet box, and the wind energy is converted into mechanical energy through the power assembly, enabling the hydraulic cylinder to provide hydraulic pressure for the hydraulic telescopic rod. The hydraulic telescopic rod jacks up the lower end of the cross beam under the continuous pressure supply of the hydraulic cylinder, making the cross beam reach a horizontal position, so that the photovoltaic power generation solar panel placed on the cross beam can be kept relatively horizontal, reducing wind resistance and minimizing the damage to the photovoltaic power generation solar panel caused by the wind.

Description

Technical Field

[0001] The present invention relates to the technical field of mounting brackets, and particularly to a mounting bracket for a photovoltaic power generation solar panel. Background Art

[0002] Photovoltaic power generation is based on the principle of the photovoltaic effect, and uses solar cells to directly convert solar energy into electrical energy. Whether used independently or for grid-connected power generation, a photovoltaic power generation system mainly consists of three major parts: solar panels (modules), a controller, and an inverter. During the installation of solar panels, brackets are required to adjust the solar panels to the most suitable angle and fix them, so that the photoelectric conversion efficiency reaches the best value. The existing installation of solar panels is fixed and has a certain inclination angle. When the wind force is relatively large, the solar panels are prone to being overturned, causing certain damage to the solar panels and affecting the normal operation of the solar panels.

[0003] Therefore, this solution specifically proposes a mounting bracket for a photovoltaic power generation solar panel to solve the above problems.

[0009] an adjustment component, the adjustment component is used to adjust the cross beam to a horizontal position when the wind force is large, reduce the wind resistance, and reduce the damage of the wind force to the photovoltaic power generation solar panel. The adjustment component includes two air inlet boxes symmetrically arranged on the cross beam. Baffles are hinged to the air inlet ends in both of the two air inlet boxes.

A rotating rod is rotatably connected outside the Z-shaped rocker. The bottom end of the rotating rod is rotatably connected to a fixed rod, and the bottom end of the fixed rod is fixedly connected to a piston.

[0011] Further, a pressurizing chamber and a hydraulic oil chamber are respectively disposed inside the hydraulic cylinder. The piston slides inside the pressurizing chamber. The hydraulic oil chamber is filled with hydraulic oil. The pressurizing chamber is communicated with the hydraulic oil chamber and is provided with a one-way oil inlet valve.

[0016] Further, a reset spring is disposed on one side of the right-angled trapezoidal slider, and the other end of the reset spring is disposed inside the sliding groove.

[0017] The beneficial effects of the present invention are embodied in that: during the use of the bracket, when encountering strong wind, the baffle is pushed up by the wind, so that the wind enters the air inlet box, and the wind energy is converted into mechanical energy through the power assembly, so that the hydraulic cylinder can provide hydraulic pressure for the hydraulic telescopic rod. The hydraulic telescopic rod jacks up the lower end of the cross beam under the continuous pressure of the hydraulic cylinder, so that the cross beam reaches the horizontal position, and the photovoltaic solar panel placed on the cross beam can be kept relatively horizontal, reducing wind resistance and reducing the damage of the wind to the photovoltaic solar panel. When the wind cannot provide power for the power assembly, the cross beam is reset under the action of the spring telescopic rod, so that the photovoltaic solar panel is reset, ensuring that the photovoltaic power generation is at the best illumination angle.

If the specific posture changes, the directional indication will also change accordingly.

[0026] See also Figures 1 to 4 :A photovoltaic solar panel support, comprising

[0027] The mounting bracket comprises a telescopic bracket 1, two supporting brackets 2 arranged outside the telescopic bracket 1, and a telescopic rod hinged at the top ends of the two supporting brackets 2;

[0028] The crossbeam 3 is used to carry the photovoltaic solar panels. The crossbeam 3 is hinged at the top end of the telescopic frame 1. Both telescopic rods are hinged under the crossbeam 3. The telescopic rod at the lower end of the crossbeam 3 is a hydraulic telescopic rod 4 that requires continuous pressurization, and the telescopic rod at the upper end of the crossbeam 3 is a spring telescopic rod 5;

[0029] The adjusting assembly is used to adjust the crossbeam 3 to a horizontal position when the wind force is large, reduce wind resistance, and reduce the damage of the wind force to the photovoltaic solar panels. The adjusting assembly includes two air inlet boxes 6 symmetrically arranged on the crossbeam 3. Baffles 7 are hinged at the air inlet ends in both air inlet boxes 6. A hydraulic cylinder 8 communicated with the hydraulic telescopic rod 4 is arranged under the air inlet box 6, and a power assembly 9 for driving the hydraulic cylinder 8 to supply oil is arranged in the air inlet box 6.

[0030] In the present invention, during the use of this bracket, when encountering strong wind, the baffle 7 is pushed up by the wind force, so that the wind enters the air inlet box 6, and the wind energy is converted into mechanical energy through the power assembly 9, so that the hydraulic cylinder 8 can provide hydraulic pressure for the hydraulic telescopic rod 4. The hydraulic telescopic rod 4 jacks up the lower end of the crossbeam 3 under the continuous pressurization of the hydraulic cylinder 8, so that the crossbeam 3 reaches a horizontal position, so that the photovoltaic solar panels placed on the crossbeam 3 can be kept relatively horizontal, reduce wind resistance, and reduce the damage of the wind force to the photovoltaic solar panels. When the wind force cannot provide power for the power assembly 9, the crossbeam 3 is reset under the action of the spring telescopic rod 5, so that the photovoltaic solar panels are reset to ensure that the photovoltaic power generation is at the best illumination angle.

[0031] In an embodiment, the power assembly 9 includes a rotating shaft 901 rotating inside the air inlet box 6. A plurality of wind turbine blades 902 are arranged outside the rotating shaft 901. The bottom end of the rotating shaft 901 extends into the hydraulic cylinder 8 and is fixedly connected with a driving bevel gear 903. A driven bevel gear 904 meshing with the driving bevel gear 903 is rotatably connected inside the hydraulic cylinder 8. A Z-shaped rocker 905 is arranged on one side of the driven bevel gear 904. A rotating rod 906 is rotatably connected outside the Z-shaped rocker 905. The bottom end of the rotating rod 906 is rotatably connected with a fixed rod 907. The bottom end of the fixed rod 907 is fixedly connected with a piston 908. When the wind enters the air inlet box 6, the rotating shaft 901 is driven to rotate by the wind turbine blades 902. The rotating shaft 901 drives the piston 908 to reciprocate up and down through the driving bevel gear 903, the driven bevel gear 904, the Z-shaped rocker 905 and the fixed rod 907, realizing the conversion of wind energy into mechanical energy.

[0032] In one embodiment, a pressurizing chamber 801 and a hydraulic oil chamber 802 are respectively arranged in the hydraulic cylinder 8. A piston 908 slides in the pressurizing chamber 801. The hydraulic oil chamber 802 is filled with hydraulic oil. The pressurizing chamber 801 is communicated with the hydraulic oil chamber 802 and is provided with a one-way oil inlet valve. The pressurizing chamber 801 is communicated with the hydraulic telescopic rod 4 through a connecting pipe 803, and the hydraulic oil chamber 802 is communicated with the hydraulic telescopic rod 4 through a return pipe 804. During the continuous reciprocating up and down movement of the piston 908 in the pressurizing chamber 801, the hydraulic oil in the hydraulic chamber is continuously conveyed into the hydraulic telescopic rod 4, and the hydraulic telescopic rod 4 supports the cross beam 3, so that the cross beam 3 maintains a relatively horizontal position when the wind force is large.

[0033] In one embodiment, an elastic member 10 is arranged inside the baffle 7. An inclined hole 701 is formed in the air inlet box 6. The side of the inclined hole 701 close to the baffle 7 is lower. A gravity block 702 slides in the inclined hole 701. One end of the gravity block 702 is provided with a clamping block 703 for easily clamping the baffle 7. When the cross beam 3 is adjusted to the horizontal position, the gravity block 702 slides to the bottom end of the inclined hole 701 under the action of gravity, and clamps the baffle 7 through the clamping block 703. After the cross beam 3 is reset, the gravity block 702 slides under the action of gravity, so that the clamping block 703 disengages from the baffle 7, and the baffle 7 is reset under the action of the elastic member 10, and the air inlet end of the air inlet box 6 is blocked again. Moreover, the elastic member 10 can prevent the wind from entering the air inlet box 6 when the baffle 7 is opened when the wind force is small.

[0034] In one embodiment, the telescopic frame 1 includes a fixed pipe 101 and an adjusting rod 102 inserted into the fixed pipe 101. The height of the telescopic frame 1 is conveniently adjusted through the fixed pipe 101 and the adjusting rod 102.

[0035] In one embodiment, the support frame 2 is hinged outside the telescopic frame 1 and a fixing bolt for fixing the support frame 2 is arranged at the hinge. The support frame 2 is conveniently fixed through the fixing bolt, and the phenomenon that the support frame 2 shakes and affects the fixing of the cross beam 3 is avoided.

[0036] In one embodiment, a sliding groove is formed outside the fixed pipe 101. A right trapezoidal slider 103 is slidably connected in the sliding groove. A clamping groove 104 adapted to the right trapezoidal slider 103 is formed outside the fixing rod 907. The position of the adjusting rod 102 is conveniently adjusted and fixed through the right trapezoidal slider 103 and the clamping groove 104. It is convenient to adjust and can avoid the phenomenon of rusting in the traditional bolt fixing, which affects the adjustment of the fixing rod 907.

[0037] In one embodiment, a return spring 105 is arranged on one side of the right trapezoidal slider 103, and the other end of the return spring 105 is arranged in the sliding groove. The right trapezoidal slider 103 is conveniently pressed tightly through the return spring 105, and the phenomenon that the right trapezoidal slider 103 disengages is avoided.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
