Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel brackets, and in particular to a photovoltaic panel bracket. Background Art

[0002] Photovoltaic panels are a type of power generation device that uses solar energy to convert into electrical energy. Its working principle is based on the photoelectric effect. Solar cells convert sunlight into direct current, and then the direct current is converted into alternating current through an inverter. Photovoltaic panels themselves do not generate electromagnetic radiation, so they will not cause harm to the human body or pollute the surrounding environment.

[0003] When installing photovoltaic panels outdoors, the photovoltaic panel bracket is an essential main support.

[0004] Chinese utility model patent with publication number CN220368658U: A photovoltaic panel bracket discloses a design with a first buried part and a second buried part, which can increase the contact area with the ground. The friction force exerted on the first buried part and the second buried part is increased, so that the legs can be fixed to the ground through the first buried part and the second buried part more firmly. The legs are not easy to shake after long-term use, further preventing the photovoltaic panel bracket from shaking or tipping over.

[0005] Although the technical solution of the above utility model patent can strengthen the connection with the ground, thereby achieving the effect of improving the stability of the photovoltaic panel bracket, it cannot effectively protect the photovoltaic panel body. In addition, the photovoltaic panel bracket of the prior art cannot achieve adaptive protection of the photovoltaic panel against weather changes while saving material costs. Therefore, the field urgently needs the photovoltaic panel bracket of the utility model to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of the utility model is to provide a photovoltaic panel bracket to solve the above-mentioned deficiencies in the prior art.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The photovoltaic panel support comprises a photovoltaic panel support frame, wherein the photovoltaic panel support frame is a limit frame; the photovoltaic panel is installed in the limit frame; the limit frame comprises a detachable semi-enclosed frame connected end to end and a sealing frame stop bar;

[0009] An upper limit piece is arranged on the upper surface of the limit frame, and a lower limit piece is arranged on the lower surface of the limit frame; the upper limit piece limits the photovoltaic panel upward, and the lower limit piece limits the photovoltaic panel downward, and the lower limit piece supports the photovoltaic panel;

[0010] By adopting the above technical solution, the connection between the sealing frame stopper and the semi-enclosed frame is disassembled, and the photovoltaic panel is slid into between the upper limit plate and the lower limit plate from the notch of the semi-enclosed frame, and then the sealing frame stopper is installed back to its position, thus completing the all-round limit installation of the photovoltaic panel;

[0011] The photovoltaic panel support also includes a protective frame, which includes a bottom frame and a vertical plate frame, and the bottom frame is provided with a vertical plate frame; the bottom frame can support the limit frame, and when the limit frame is located inside the protective frame, the vertical plate frame can protect the limit frame and block strong winds;

[0012] The limit frame is installed in the protection frame, and one end of the limit frame is rotatably connected to the protection frame. When encountering bad weather or when the bracket is not put into use on site, the limit frame is folded into the protection frame, and the vertical plate frame can block and protect the limit frame and the photovoltaic panel inside from strong winds, so as to prevent the photovoltaic panel from being damaged by wind.

[0013] The bottom of the free end of the limiting frame is rotatably connected to a support rod;

[0014] By adopting the above technical solution, when the photovoltaic panel needs to produce an inclination angle to cater to the sunlight, the free end of the limit frame is lifted, the support rod is rotated, and the bottom end of the support rod is placed against the bottom frame; when the photovoltaic panel needs to be protected, the support rod is rotated to be parallel to the photovoltaic panel, and the limit frame is rotated into the protection range of the vertical plate frame.

[0015] As a preferred solution, the protective frame includes three L-shaped frame edges connected end to end and one steel bar. The straight plate at the bottom end of the L-shaped frame edge is connected end to end with the steel bar to form a bottom frame, and the straight plate at the upper end of the L-shaped frame edge is connected end to end to form a vertical plate frame. In rainy weather, the steel bar area can drain water smoothly to avoid rainwater accumulation.

[0016] As a preferred solution, a rotating connection hole is horizontally opened at one end of the L-shaped frame edge near the steel bar, and a rotating shaft is installed at the end of the outer wall of the semi-enclosed frame away from the sealing frame baffle, and the rotating shaft is rotatably connected to the rotating connection hole.

[0017] As a preferred solution, a structural reinforcement bar is installed in the bottom frame, and both ends of the structural reinforcement bar are fixedly connected to the bottom frame diagonally, so as to strengthen the structural strength of the bottom frame in a triangle.

[0018] As a preferred solution, support connection holes are vertically opened on the L-shaped frame edge and the steel bar, and support members are installed in the support connection holes by bolt connection. The support members are located below the support connection holes, and the bottom ends of the support members are connected and fixed to the ground.

[0019] As a preferred solution, the semi-enclosed frame is provided with a rounded corner at the bottom near one end of the steel bar. The rounded corner design can reduce the vertical span when the semi-enclosed frame is rotated near one end of the steel bar. During production, the vertical span of the vertical plate frame can be reduced to save raw materials, and the overall size of the photovoltaic panel bracket can be made smaller, thinner, and easier to transport and carry.

[0020] As a preferred solution, a water guide clamp is installed at one end of the semi-enclosed frame close to the steel bar.

[0021] As a preferred solution, a water guide clamp is welded to the top of one end of the semi-enclosed frame near the steel bar. The water guide clamp has the same structure as the upper part of the water guide clamp of the photovoltaic panel in the prior art. The structure of the water guide clamp in the prior art refers to the Chinese utility model patent with publication number CN220234590U. The designed water guide clamp has the water guiding function of the upper part of the water guide clamp in the prior art, and the lower part of the water guide clamp in the prior art is optimized and deleted. Since it is a welded structure, the lower part of the water guide clamp in the prior art is not needed, and the clamping and fixing function of the water guide clamp in the prior art does not need to be maintained. While realizing the water guiding function, the raw material cost is saved.

[0022] As a preferred solution, a slide rail is installed on the bottom frame, and a slider is slidably installed on the slide rail. The top of the slider is rotatably connected to the bottom end of the support rod by a rotating shaft structure. An inverted L-shaped connector is fixedly connected to the side wall of the slider. The inverted L-shaped connector is fixedly connected to the end away from the slider with a total driving rod. Several photovoltaic panel brackets are arranged in a row and installed at the same angle. The total driving rod is fixedly connected to the inverted L-shaped connectors in all photovoltaic panel brackets. A servo linear motor is transmission-connected to the end of the total driving rod. Pushing the total driving rod can drive the bottom end of the support rod to slide and move, thereby realizing the adjustment of the inclination angle of the photovoltaic panel. The photovoltaic panel can be uniformly and adaptively adjusted according to the changes in the angle of sunlight, thereby improving the power output.

[0023] As a preferred solution, the semi-enclosed frame is connected to the sealing frame bar by bolts.

[0043] By adopting the above technical solution, the connection between the sealing frame stopper 203 and the semi-enclosed frame 201 is disassembled, and the photovoltaic panel 301 is slid and pushed into between the upper limit piece 205 and the lower limit piece 206 from the notch of the semi-enclosed frame 201, and then the sealing frame stopper 203 is installed back to its original position, thus completing the all-round limit installation of the photovoltaic panel 301;

[0044] The photovoltaic panel support also includes a protective frame, which includes a bottom frame and a vertical plate frame, and the vertical plate frame is welded on the bottom frame; the bottom frame can support the limit frame, and when the limit frame is located inside the protective frame, the vertical plate frame can protect the limit frame and block strong winds;

[0045] The limit frame is installed in the protection frame, and one end of the limit frame is rotatably connected to the protection frame. When encountering bad weather or when the bracket is not put into use on site, the limit frame is folded into the protection frame, and the vertical plate frame can block the limit frame and the photovoltaic panel 301 inside from strong winds to prevent the photovoltaic panel from being damaged by wind.

[0046] The bottom of the free end of the limiting frame is rotatably connected to a support rod 401 .

The structure of the water guide clamp in the prior art refers to the Chinese utility model patent with publication number CN220234590U. The water guide clamp 601 is designed to have the water guiding function of the upper part of the water guide clamp in the prior art, and the lower part of the water guide clamp in the prior art is optimized and deleted.

[0054] A slide rail 402 is installed on the bottom frame, and a slider 403 is slidably installed on the slide rail 402. The top of the slider 403 is rotatably connected to the bottom end of the support rod 401 by a rotating shaft structure.

The total driving rod 502 is connected and fixed to the inverted L-shaped connector 501 in all photovoltaic panel brackets. A servo linear motor is transmission-connected to the end of the total driving rod 502. Pushing the total driving rod 502 can drive the bottom end of the support rod 401 to slide and move, thereby realizing the adjustment of the inclination angle of the photovoltaic panel 301. According to the change of the angle of sunlight, the photovoltaic panel 301 can be uniformly and adaptively adjusted to improve the power output.
