Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a photovoltaic bracket with adjustable height and angle. Background Art

[0002] In the photovoltaic power station project, the pile foundation project and installation project of the photovoltaic bracket are the parts with the largest civil engineering and mechanical and electrical engineering quantities in the whole photovoltaic power station. The existing photovoltaic brackets generally adopt a portal frame structure, with columns supporting inclined beams, purlins installed on the inclined beams, and photovoltaic modules installed on the purlins. At present, the photovoltaic brackets on the market are divided into two types: non-adjustable angle and adjustable angle. Most of the photovoltaic adjustable brackets adopt multiple push rod arms connected to realize the angle adjustment and positioning of the bracket. Users need to adjust each push rod to realize the angle adjustment of the bracket, with low adjustment efficiency and difficult to ensure consistency. At the same time, the height of the photovoltaic panel cannot be adjusted, reducing the applicability. Summary of the Invention

[0003] The purpose of the utility model is to provide a photovoltaic bracket with adjustable height and angle, which is reasonable in design and convenient to use, and can effectively solve the defects existing in the above-mentioned prior art.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions: It includes a bottom plate, a support rod and an installation rod. Installation rods are arranged on the left and right sides above the bottom plate, and support rods are symmetrically arranged in the front and rear on the lower side of the installation rod. The support rods are fixed on the upper surface of the bottom plate; It also includes:

[0005] Adjusting rods, there are four adjusting rods, and they are correspondingly inserted into several support rods one by one. An installation frame is arranged at the upper end of the adjusting rod. The two installation frames at the rear are sleeved and fixed on the rear end of the installation rod, and the two installation frames at the front are movably sleeved on the front side of the installation rod. The convex rod on the lower side of the installation frame is inserted into the top wall of the installation rod and is rotatably connected through a shaft rod;

[0006] Moving blocks, there are four moving blocks, and they are symmetrically fixed in pairs on the upper sides of the left and right inner walls of the installation frame. The moving blocks are slidably arranged in the sliding grooves on the side wall of the installation rod;

[0007] Adjusting screws, there are four adjusting screws, and they are correspondingly screwed into the adjusting rods through threads. The lower end of the adjusting screw passes through the lower end of the support rod and is rotatably inserted into the bottom plate through a bearing. The two symmetrically arranged adjusting screws on the left and right are connected through a synchronous pulley transmission component;

[0008] An adjusting motor, the adjusting motor is embedded and fixed on one side inside the bottom plate, and the output shaft of the adjusting motor is fixedly connected to the bottom end of one of the adjusting screws at the rear;

[0009] Linkage mechanism, the linkage mechanism is arranged inside the bottom plate, and the linkage mechanism is connected to four adjusting screws;

[0010] Through the above technical solution, the photovoltaic panel is installed on the installation rods on both sides. According to the required height of the photovoltaic panel, the adjustment motor is started, and the adjustment motor drives the connected adjustment screw to rotate. The adjustment screw drives another adjustment screw at the rear to rotate through the synchronous pulley transmission assembly. The adjustment screw at the rear drives the two adjustment screws at the front to rotate through the linkage mechanism. During the rotation of the adjustment screw, it drives the adjustment rod to move up and down. The adjustment rod drives the installation rod to move up and down, and the installation rod drives the photovoltaic panel to move up and down to a suitable height. When the angle needs to be adjusted, the linkage mechanism is separated from the adjustment screw at the front, so that the adjustment motor only drives the adjustment screw at the rear to rotate. The adjustment screw at the rear drives the adjustment rod inside it to move upward. The adjustment screw drives the rear end of the installation rod to move upward through the mounting bracket. At this time, the movable block at the front slides in the chute on the side wall of the installation rod until the photovoltaic panel rotates to a suitable angle.

[0011] As a further improvement of the present invention, anti-slip soft pads are fixed on the upper surfaces of the installation rods.

[0012] As a further improvement of the present invention, limit blocks are arranged in the chutes on the left and right inner walls of the adjustment rod, and the limit blocks are fixed on the inner walls on the left and right sides of the support rod;

[0013] Through the above technical solution, it is convenient to limit the adjustment rod and prevent the adjustment rod from falling out of the support rod.

[0014] As a further improvement of the present invention, the linkage mechanism includes:

[0015] Rotating frames, there are two rotating frames, and they are symmetrically arranged left and right inside the bottom plate. The front and rear ends of the rotating frames are rotatably connected to the rotating rods through bearings. After the upper and lower ends of the two rotating rods at the rear pass through the rotating frames, they are rotatably connected inside the bottom plate through bearings. The rotating rods are respectively connected to the adjacent adjustment screws through gear pairs, and the two rotating rods that are symmetrically arranged front and rear are connected through a synchronous pulley transmission assembly;

[0016] Adjusting blocks, there are two adjusting blocks, and they are respectively embedded in the rectangular holes at the centers of the rotating frames. Moving blocks are rotatably connected to the upper and lower side walls of the adjusting blocks through shaft rods, and the moving blocks slide in the chutes on the upper and lower inner walls of the rectangular holes;

[0017] Bidirectional lead screw, the bidirectional lead screw is embedded and rotatably connected inside the bottom plate through a bearing. The two ends of the bidirectional lead screw are respectively screwed into the moving blocks through threads. One end of the bidirectional lead screw is fixed with a linkage motor, and the linkage motor is embedded and fixed inside one side of the bottom plate;

[0018] Through the above technical solution, when the rear adjusting screw rotates, it drives the rear rotating rod to rotate through the gear pair. The rear rotating rod drives the front rotating rod to rotate through the synchronous pulley transmission assembly, and the front rotating rod drives the front adjusting screw to rotate, so that the four adjusting screws rotate synchronously. When the angle needs to be adjusted, the linkage motor is started. The linkage motor drives the bidirectional lead screw to rotate, and the bidirectional lead screw drives the two adjusting blocks to move. The adjusting block drives the rotating frame to rotate around the rear rotating rod through the moving block, so that the gear on the front rotating rod is separated from the gear on the front adjusting screw. At this time, the two rear adjusting screws will not drive the front adjusting screw to rotate, achieving the effect of adjusting the angle.

[0019] As a further improvement of the present invention, arc-shaped blocks are fixedly arranged on the front sides of the outer bottom wall of the rotating frame, and the arc-shaped blocks are slidably arranged in the arc-shaped grooves on the inner wall of the bottom plate; the stability of the rotating frame during rotation can be increased.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: The photovoltaic bracket with adjustable height and angle of the present invention can adjust the angle of the photovoltaic panel according to requirements, and can also synchronously adjust the heights of the front and rear sides of the photovoltaic panel according to the required requirements, improving the applicability. The present invention has the advantages of reasonable setting and low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS
