Description

Technical Field

[0001] This invention relates to the field of solar photovoltaic equipment technology, specifically to an adjustable photovoltaic panel array mounting bracket and its installation method. Background Technology

[0002] With the rapid development of the solar photovoltaic power generation industry, the installation brackets of photovoltaic panel arrays, as the core supporting components of photovoltaic systems, directly affect the photovoltaic conversion efficiency and operation and maintenance costs.

[0003] Most existing photovoltaic (PV) panel array mounting brackets use fixed structures, which cannot adjust the PV panel orientation according to diurnal and seasonal changes in solar azimuth and altitude angles. This results in insufficient solar radiation received by the PV panels and low PV conversion efficiency. Some adjustable brackets can only achieve single-dimensional adjustment, such as tilt angle adjustment in different seasons, and require manual operation, which is cumbersome and has a slow response time. In addition, large-scale PV stations require multiple brackets to work together. Existing adjustable brackets are mostly independently controlled, requiring each adjustable bracket to be equipped with an independent drive device, resulting in high cost, complex control, and high energy consumption for the entire system.

[0004] Therefore, there is a need for an adjustable photovoltaic panel array mounting bracket with a reasonable structure, stable drive, and linkage control. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides an adjustable photovoltaic panel array mounting bracket and its installation method, which solves the problems of the inability to adjust the transmission fixed bracket and the inability to adjust the adjustable bracket synchronously, thereby reducing the overall cost.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: an adjustable photovoltaic panel array mounting bracket, comprising:

[0009] A base, wherein a support cylinder is vertically fixed to the top of the base, and a rotating support seat is fixedly connected to the top of the support cylinder;

[0010] A rotating platform, wherein the rotating platform is rotatably connected to the top of a rotating support base, and a rotating base is fixedly connected to the center of the top of the rotating platform;

[0011] A photovoltaic mounting frame, wherein the bottom center of the photovoltaic mounting frame is rotatably connected to a rotating seat, and connecting seats are symmetrically fixed on both sides of the bottom of the photovoltaic mounting frame;

[0012] The tilt adjustment mechanism includes a T-shaped guide rail symmetrically arranged on the surface of the support cylinder, an arc-shaped lifting seat slidably connected to the T-shaped guide rail, a sliding support seat slidably connected to the arc-shaped surface of the arc-shaped lifting seat, and a support rod whose two ends are respectively rotatably connected to the sliding support seat and the connecting seat. The T-shaped guide rail is vertically arranged.

[0013] A hybrid drive structure is disposed inside the support cylinder. The hybrid drive structure drives the rotating platform to rotate around the vertical axis through a first drive source to adjust the azimuth angle. The hybrid drive structure drives the two arc-shaped lifting seats to move vertically along the T-shaped guide rail in opposite directions and at equal distances through a second drive source. In turn, the support rod pushes the photovoltaic mounting frame to rotate around the rotating seat to adjust the tilt angle.

[0014] The rotation centers of the rotating seat and the two connecting seats are located in the same plane, and the rotation center of the sliding support seat that slides around the arc-shaped surface of the arc-shaped lifting seat is coaxial with the rotation center of the rotating platform.

[0015] Preferably, the hybrid drive structure includes:

[0016] A central shaft, the bottom end of which is rotatably connected to the top of the base, and the top end of which is fixedly connected to the bottom center of the rotating platform;

The bottom ends of the first lead screw and the second lead screw are rotatably connected to the top of the base. The first lead screw and the second lead screw have opposite directions of rotation.

[0018] A first worm gear is fixedly connected to the surface of the central shaft. A first worm is meshed with one side of the first worm gear. A first drive shaft is fixedly connected to the center of the first worm. Both ends of the first drive shaft are rotatably connected to the support cylinder and extend to its outside.

Only the drive shaft at one end of the array needs to be driven to achieve synchronous adjustment of the entire array. When using motor drive, the number of drive motors is greatly reduced, or when using manual operation, the number of adjustments is reduced, thus improving efficiency.

[0026] Preferably, the first connecting shaft and the second connecting shaft have the same structure.

[0033] Steps: Debugging: Add grease to the rotating parts of the hybrid drive structure, and check the rotation of the rotating platform and the movement of the arc-shaped lifting seat by connecting an external drive source.

[0034] Preferably, the hybrid drive structure, rotating seat, and rotating platform are pre-assembled in the factory to improve on-site installation efficiency and quality.

[0035] (III) Beneficial Effects

[0036] This invention provides an adjustable photovoltaic panel array mounting bracket and its installation method. It has the following advantages:

[0037] (1) By integrating the complex hybrid drive structure into the support cylinder, the structure is compact and has good protection; the double screw symmetrical drive tilt angle adjustment makes the photovoltaic installation frame subjected to balanced forces on both sides, runs smoothly, and has strong resistance to wind and snow loads.

[0038] (2) Through the dual drive source design of the hybrid drive structure, the horizontal rotation of the rotating platform can be realized to adapt to the change of solar azimuth angle, and the tilt angle of the photovoltaic installation frame can be adjusted to adapt to the change of solar altitude angle.

[0039] (3) The synchronous horizontal rotation and tilt adjustment of multiple sets of supports can be realized through the connecting shaft. When the motor is driven, only two motors are needed for each row to realize the horizontal rotation and tilt adjustment respectively, which significantly reduces the number of motors, reducers and controllers, and reduces the cost and energy consumption of the whole system. When manual adjustment or adjustment with the help of power tools is used, the entire row of supports can be synchronously adjusted on only one side, which improves work efficiency.

[0040] (4) The hybrid drive structure, rotating support base and rotating platform and other components can be pre-assembled in the factory. On-site installation only requires base fixing, bracket splicing, connecting shaft connection and debugging, which improves installation efficiency. Attached Figure Description

[0067] An installation method for an adjustable photovoltaic panel array mounting bracket, applicable to the aforementioned adjustable photovoltaic panel array mounting bracket, includes the following steps:

[0068] Step 1: Fix the base. Fix the base 1 on the preset installation base, and complete the positioning and fixing after calibrating the level.

[0069] Step 2: Photovoltaic mounting frame assembly. Connect the photovoltaic mounting frame 6 to the rotating seat 5 by rotation. Fix the connecting seats 7 symmetrically on both sides of the bottom of the photovoltaic mounting frame 6.

[0070] Step 3: Support rod installation: Adjust the sliding support seat 10 to the corresponding position below the connecting seat 7, and install the support rod 11 between the sliding support seat 10 and the connecting seat 7;

[0071] Step 4: Multi-bracket linkage assembly: Along the axial direction of the first drive shaft 19, install multiple mounting brackets according to steps 1-3, connect the first drive shaft 19 of adjacent brackets with the first connecting shaft 28, and connect the second drive shaft 25 of adjacent brackets with the second connecting shaft 29;

[0072] Step 5: Debugging: Add grease to the rotating parts of the hybrid drive structure, and check the rotation of the rotating platform 4 and the movement of the arc-shaped lifting seat 9 by connecting an external drive source.

[0073] The hybrid drive structure, rotating base 3, and rotating platform 4 are pre-assembled in the factory, improving on-site installation efficiency.

[0074] During work:

[0075] Azimuth adjustment: The first drive shaft 19 is rotated by an external motor or by manual drive. The first connecting shaft 28 drives other first drive shafts 19 to rotate. Then, the first worm wheel 17 and the central shaft 12 are rotated through the corresponding first worm 18, thereby driving the entire rotating platform 4 and the photovoltaic mounting frame 6 on it to rotate around the vertical axis to track the solar azimuth.

[0076] Tilt adjustment: An external motor or manual drive rotates the second drive shaft 25, which in turn drives the other second drive shafts 25 to rotate. This, in turn, drives the second worm gear 23 and the first lead screw 14 to rotate via the corresponding second worm 24. The first lead screw 14, through the transmission of the first gear 20, the third gear 22, and the second gear 21, drives the second lead screw 15 to rotate at the same speed. This causes the two moving seats 16 to move upwards and downwards respectively, driving the two arc-shaped lifting seats 9 to move in opposite directions at equal distances along the T-shaped guide rail 8. Through the pushing and pulling action of the support rod 11, the photovoltaic mounting frame 6 rotates around the rotating seat 5, changing the tilt angle to track the solar altitude angle. The sliding of the sliding support seat 10 on the arc-shaped lifting seat 9 compensates for the change in the position of the bottom end of the support rod 11 caused by the azimuth angle rotation.
