Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic equipment, and in particular to a modular photovoltaic component and an array assembly method. Background Art

[0002] Photovoltaic is the abbreviation of solar photovoltaic power generation system, which is a new power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. Solar energy is a rapidly growing form of energy, and the solar energy market has also made great progress in the past decade. Solar power generation is an emerging renewable energy technology, and the main ones that have been industrialized are solar photovoltaic power generation and solar thermal power generation.

[0003] Existing solar photovoltaic power generation usually includes photovoltaic panels and supporting structures of photovoltaic panels. The angle of the photovoltaic panels is adjusted by the supporting structure to achieve the best photoelectric conversion. For example, Chinese patent announcement number CN117277961A discloses "photovoltaic module control module and photovoltaic module", which enables the photovoltaic module to be remotely monitored and controlled by setting a monitoring mechanism and a control mechanism. By setting a temperature and humidity sensor and a light sensor, the light signal and the temperature and humidity signal at the photovoltaic module can be monitored, and then the monitoring signal is sent to the controller, and then the controller sends the monitoring data to the remote control center through the communication module. At the same time, the communication module can receive remote control instructions and control the first motor, the second motor and the telescopic cylinder through the controller. The first motor can drive the first gear to rotate, and through the meshing action between the first gear and the second gear, drive the screw to rotate, thereby driving the photovoltaic module body to rotate through the slider and the transmission rod to adjust the angle of the photovoltaic module body;

[0004] However, in the actual installation of the array, photovoltaic modules not only require a higher photoelectric conversion rate, but also need to be easy to install and calibrate. The use of control structures such as motors not only makes the transportation and installation process cumbersome and increases costs, but also leads to additional energy consumption. The actual net power generation of photovoltaic modules is reduced. At the same time, the life of motors and other control structures in the natural environment will also be reduced, increasing maintenance costs. Summary of the invention

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figure 1-5 A modular photovoltaic assembly includes a photovoltaic module 1, a mounting module 2 and a bracket 3. The photovoltaic module 1 is connected to the bracket 3 through the mounting module 2. The photovoltaic module 1 includes a frame 11 and a photovoltaic panel 12 arranged in the frame 11. The mounting module 2 includes a support frame 21. A rotating mechanism 4 is arranged between the support frame 21 and the frame 11. The mounting module 2 also includes a connecting component 5 connected to the bracket 3. An angle adjustment mechanism 6 is arranged between the bracket 3 and the mounting module 2.

[0033] The angle adjustment mechanism 6 includes two connection blocks 61 rotatably connected to the bracket 3 and the support frame 21 respectively. A threaded column 62 is fixedly provided on each of the connection blocks 61 , and a connection frame 63 is threadedly connected between the two threaded columns 62 .

[0034] In the present invention, by dividing the photovoltaic assembly into a photovoltaic module 1, a mounting module 2 and a bracket 3, transportation and storage are facilitated, space utilization is improved, transportation costs and storage costs are reduced, and it is also convenient to assemble the array and increase assembly efficiency. The support frame 21 of the mounting module 2 is rotatably connected to the frame 11 through a rotating mechanism 4, so that the photovoltaic module 1 can be rotated left and right to adjust the angle. The mounting module 2 is rotatably connected to the bracket 3 through a connecting component 5, so that the mounting module 2 and the photovoltaic module 1 can be rotated up and down to adjust the angle. At the same time, the angle of the mounting module 2 and the photovoltaic module 1 is adjusted and fixed through an angle adjustment mechanism 6, which is convenient for calibration and improves the photoelectric conversion efficiency.

[0035] Furthermore, in this embodiment, the rotating mechanism 4 includes a bearing seat 41 fixedly arranged on the support frame 21, and a rotating shaft 42 rotatably connected to the bearing seat 41 is fixedly arranged on the frame 11. The frame 11 can rotate left and right with the rotating shaft 42 as the center to adjust the angle, which is convenient for calibrating the angle of the photovoltaic panel 12 and improving the photoelectric conversion efficiency.

[0036] In this embodiment, a mounting hole 43 corresponding to the rotating shaft 42 is opened on the bearing seat 41, and a damping structure 7 matching the rotating shaft 42 is provided in the mounting hole 43. The damping structure 7 is provided to increase the difficulty of rotating the frame 11, and the angle of the frame 11 is preliminarily fixed to prevent the frame 11 from being reset due to gravity after the angle is adjusted, resulting in failure of angle adjustment.

[0037] Furthermore, in the present embodiment, the damping structure 7 includes a damping block 71 arranged in the mounting hole 43, and a plurality of connecting holes 72 are opened on the damping block 71. The connecting holes 72 are connected to the damping member 73 through a spring. When the rotating shaft 42 rotates, the damping member 73 abuts against the rotating shaft 42 to increase the friction force, so that resistance is generated when the rotating shaft 42 rotates. In some embodiments, a guide portion is provided in the mounting hole 43 to limit the damping block 71 and prevent it from rotating, so that the damping block 71 can only move forward and backward.

[0038] In this embodiment, a plurality of sockets are provided on the rotating shaft 42 to cooperate with the damping member 73. The damping member 73 is a columnar structure with a ball head, and its ball head portion is inserted into the socket. When the rotating shaft 42 rotates, the socket abuts against the ball head, so that the damping member 73 moves backward to squeeze the spring, generating resistance. When the damping member 73 is misaligned with the socket, the ball head abuts against the rotating shaft 42 to increase friction. A rotating member 74 is rotatably provided on one side of the damping block 71. A threaded portion 75 is fixedly connected to one end of the rotating member 74. The threaded portion 75 is threadedly connected to the mounting hole 43. When it is necessary to fix the angle of the rotating shaft 42 and the photovoltaic module 1, the rotating member 74 and the damping block 71 are driven to move by rotating the threaded portion 75, and the ball head of the damping member 73 is completely inserted into the socket, and the inscribed part of the columnar structure is also inserted into the socket, thereby hindering the rotation of the rotating shaft. In some embodiments, a handle is provided on the threaded portion 75 for easy rotation.

[0039] It should be noted that, in this embodiment, the connecting component 5 includes a support member 22, a mounting plate 23 that cooperates with the support member 22 is fixedly provided on the support frame 21, and a kit 24 that is rotatably connected to the support member 22 is sleeved on the bracket 3. The kit 24 is snap-fitted to the bracket 3 and does not rotate itself. The support member 22 and the mounting module 2 can be rotated up and down in a circle with the kit 24 to adjust the angle.

[0040] In this embodiment, the support member 22 includes a clamp 221, a support plate 222 and a top plate 223. A slide groove is provided on the top plate 223. A slider 231 slidably connected to the slide groove is fixedly provided on the mounting plate 23. The slide groove is a dovetail groove or a T-shaped groove, and the slider 231 is a corresponding dovetail block or T-shaped block.

[0041] In addition, in the present embodiment, a positioning glass bead 224 is provided in the slide groove, a positioning hole matching the positioning glass bead 224 is provided on the slider 231, a through hole corresponding to the positioning hole is provided on the mounting plate 23, a pressure rod 225 is movably inserted in the through hole, and the positioning glass bead 224 cooperates with the positioning hole, and when the support frame is connected to the support member 22, the slider 231 moves along the slide groove until the positioning hole is engaged with the positioning glass bead 224, that is, it is installed in place. When disassembling, the positioning glass bead 224 can be separated from the positioning hole by applying force to the pressure rod 225 to move it downward and squeeze the positioning glass bead, thereby not hindering the movement of the slider 231.

[0042] In more detail, in this embodiment, the clamp 221 is movably mounted on the outside of the kit 24, and a fixing part 226 for controlling the clamp 221 is provided on the clamp 221. The tightness of the clamp 221 is adjusted by setting the fixing part 226. The fixing part 226 can be a bolt, a screw, or other structures that can play a fixing role.

[0043] The present invention further proposes a method for assembling an array of modular photovoltaic modules, comprising the above-mentioned modular photovoltaic modules, and further comprising the following steps:

[0044] S1. Multiple photovoltaic modules 1 are sequentially installed in an array on the bracket 3 through the installation module 2. During installation, the clamp 221 on the support 22 is plugged into the kit 24 on the bracket 3, and the slider 231 on the support frame 21 is plugged into the slide groove on the support 22. After being plugged into place, the positioning glass bead 224 is plugged into the positioning hole;

[0045] S2, adjusting the angles of the mounting module 2 and the photovoltaic module 1 by threading the connection frame 63 with the two threaded posts 62;
