[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0019] like Figure 1 , Figure 2 As shown, a supporting mechanism for facilitating installation of a photovoltaic module provided by an embodiment of the present invention includes a first bracket 1, the first bracket 1 is composed of a first crossbar 101 and a first vertical frame 102 fixedly connected to both ends of the first crossbar 101, and also includes: The second bracket 2 is arranged at an interval relative to the first bracket 1, and the second bracket 2 is composed of a second crossbar 201 and a second vertical frame 202 fixedly connected to both ends of the second crossbar 201. The first vertical frame 102 and the second vertical frame 202 on the same side are connected by a horizontally arranged crossbar 3, and the height of the first vertical frame 102 is less than that of the second vertical frame 202. The second vertical frame 202 includes a support leg 2021 at the bottom, and a combined box body 2022 is fixedly connected to the top of the support leg 2021. A driving member 4 is arranged outside the combined box body 2022, and a transmission assembly is arranged inside the combined box body 2022; The strip bracket 5 is located at the top of the first bracket 1 and the second bracket 2. The strip bracket 5 includes a strip box 501 connected to the top of the first vertical frame 102 at one end, and the other end of the strip box 501 is connected to the top of the combined box 2022. A self-locking drag chain structure 502 is provided in the strip box 501. A through groove surrounding the strip box 501 is provided on the strip box 501. A mounting block 503 located in the through groove is fixedly provided on the drag chain structure 502. The mounting block 503 is provided with a mounting hole for mounting the photovoltaic module 19. The transmission assembly in the combined box 2022 is connected to the drag chain structure 502 through the shaft that penetrates the combined box 2022 and the strip box 501. When the driving member 4 rotates, the drag chain structure 502 in the strip box 501 is driven to rotate through the transmission assembly.

[0020] In one embodiment of the present invention, the support mechanism utilizes the characteristic that most of the photovoltaic components 19 are tilted to tilt the strip box 501. In the actual installation process, due to the lower height of the first vertical frame 102, the construction personnel first install a photovoltaic component 19 on the mounting blocks 503 on both sides. After the installation is completed, the driving member 4 can drive the transmission assembly to operate, so that the drag chain structure 502 of the strip box 501 rotates, and then the installed photovoltaic components 19 are lifted to a higher place. In this way, the photovoltaic components 19 installed at a low position are gradually lifted to a high position, which makes it more convenient for the construction personnel to carry or install the photovoltaic components 19, thereby improving the overall installation efficiency. In addition, the support mechanism does not use a complex mechanism for driving and controlling, and the overall shape still maintains a similar appearance to the steel structure. On the basis of ensuring stability, it also meets the requirements for use in the field environment.

[0021] In one embodiment of the present invention, Figure 7 As shown, the driving member 4 itself does not provide power, but is connected to an external power source. Because the support mechanism is set in the field environment, if a motor-like component is set as a power source, this method is obviously not applicable. The driving member 4 can be a special connector, which can be connected to a handheld electric drill tool carried by the construction personnel, which adds restrictions on the use of the support mechanism and increases safety, so that only professionals can use it. The driving member 4 will only be connected when installing or disassembling the photovoltaic module 19.

[0022] like Figure 3 and Figure 4As shown, as a preferred embodiment of the present invention, the strip box 501 includes a main box 5011 connected to the combined box 2022 and the first vertical frame 102, a side plate 5012 is arranged at intervals on one side of the main box 5011, a plurality of mounting rollers 6 are rotatably arranged in the main box 5011, the mounting rollers 6 are arranged at intervals along the length direction of the main box 5011, and one of the mounting rollers 6 is fixedly connected to one end of the shaft body, the drag chain structure 502 is arranged on the mounting roller 6, the gap between the side plate 5012 and the main box 5011 constitutes the through groove, the side plate 5012 is fixedly connected to the main box 5011 through a connecting bolt 7, and a locking pin 8 is arranged on one end of the side plate 5012 close to the first vertical frame 102, and the locking pin 8 is used to limit the rotation of the mounting roller 6 at the corresponding position in the main box 5011, so that the drag chain structure 502 is locked.

[0023] In one case of the present embodiment, a hollow shaft 9 is rotatably connected to the corresponding position of the locking pin 8 in the main box body 5011, and the installation roller 6 is fixed on the hollow shaft 9. The locking pin 8 is used to be inserted into the hollow shaft 9 so that the rotation of the hollow shaft 9 is restricted. After the drag chain structure 502 gradually lifts the photovoltaic components 19, they will remain arranged on the strip box body 501. However, the photovoltaic components 19 have their own weight. If they are not locked, the photovoltaic components 19 will automatically fall. When one installation roller 6 is restricted by the locking pin 8, the drag chain structure 502 cannot rotate, so that the installed photovoltaic component 19 remains in position. When the photovoltaic component 19 needs to be removed, the locking pins 8 on both sides can be pulled out to restore the rotation of the drag chain structure 502.

[0024] like Figure 5 , Figure 6 and Figure 7 As shown, as a preferred embodiment of the present invention, the combined box 2022 includes a first box 20221 fixedly connected to the support leg 2021, a second box 20222 is arranged on the top of the first box 20221, and a third box 20223 is slidably sleeved on the second box 20222, the transmission assembly is arranged in the first box 20221, the second box 20222 and the third box 20223, the driving member 4 is arranged on the first box 20221, and an adjustment assembly 10 is arranged on one side of the first box 20221. The adjustment assembly 10 is used to drive the third box 20223 to move in the vertical direction on the second box 20222, and both ends of the strip bracket 5 are rotatably connected to the first vertical frame 102 and the third box 20223.

[0025] In one case of this embodiment, the cross frame 3 includes a rectangular sleeve 301 fixedly connected to the first vertical frame 102 and the support leg 2021 respectively, and a rectangular tube 302 is slidably inserted between the rectangular sleeves 301 on both sides. When the third box body 20223 moves in the vertical direction to change the height of the combined box body 2022, the overall length of the cross frame 3 changes accordingly. The transmission assembly includes a driven pulley 11 arranged at the bottom of the first box body 20221 and in the third box body 20223, and also includes a driving pulley 12 arranged in the middle of the first box body 20221. The driving pulley 12 is connected to the driving member 4 outside the first box body 20221. The first box body 20221 and the second box body 2 A limit pulley 13 is provided at the joint of 0222, and a plurality of tension pulleys 14 distributed in the vertical direction are provided on the side of the first box body 20221 away from the adjustment component 10. The driven pulley 11, the driving pulley 12, the limit pulley 13 and the tension pulley 14 are provided with a transmission belt 15. It should be noted that the driven pulley 11 in the third box body 20223 is connected to the shaft body. When the height of the combined box body 2022 changes, the plurality of tension pulleys 14 can move laterally to compensate the position of the transmission belt 15. A vertical mounting plate 16 is provided on the side of the first box body 20221 away from the adjustment component 10, and a plurality of wheel frames 1 are fixedly connected to the mounting plate 16 at intervals. 7. The tension pulley 14 is rotatably arranged on the wheel frame 17. A connecting structure 18 for connecting the mounting plate 16 to the adjusting component 10 is arranged at the bottom of the first box body 20221. When the adjusting component 10 drives the third box body 20223 to move in the vertical direction, the mounting plate 16 is driven to move laterally through the connecting structure 18. Generally speaking, it is a very common technical means to use a transmission belt structure to drive the drag chain structure 502 to rotate. However, in this field, due to different regional terrains, it is impossible for the photovoltaic component 19 to maintain a fixed inclination angle for installation and setting, so the supporting mechanism needs to have an adjustment function. From the above, it can be concluded that the overall height of the second vertical frame 202 can be adjusted, but This will cause the retractable second vertical frame 202 to conflict with the transmission belt structure. Although the existing belt tensioning structure can adjust the length, this adjustment amount obviously cannot meet the height adjustment requirement of the second vertical frame 202. In the present embodiment, a plurality of tensioning pulleys 14 are used to cooperate with each other. The movement of one tensioning pulley 14 can increase the spacing between the two driven pulleys 11. As the number of tensioning pulleys 14 increases, the lifting amount of the driven pulley 11 can be greatly increased. Through reasonable settings, the adjustment of the transmission belt 15 and the height adjustment of the second vertical frame 202 can be unified. Through the above structure, the height adjustment of the support mechanism and the structural transmission can be achieved without interference.

[0026] like Figure 6As shown, as a preferred embodiment of the present invention, the adjustment component 10 includes a transmission box 1001 fixedly arranged on the outside of the first box body 20221, and a first screw rod structure 1002 is arranged at the top output end of the transmission box 1001, and the other end of the first screw rod structure 1002 is connected to the third box body 20223, and the connecting structure 18 includes a second screw rod structure located at the bottom of the first box body 20221 and arranged laterally, and the second screw rod structure is used to transmit and connect the mounting plate 16 with the transmission box 1001, and a driving handle 1003 is arranged on the transmission box 1001.

[0027] In one case of this embodiment, a gear meshing transmission structure can be set in the transmission box 1001, and of course a worm gear can also be used. When the construction personnel need to adjust the angle of the photovoltaic component 19, the first screw structure 1002 can be controlled by driving the handle 1003, so that the third box body 20223 can be raised and lowered on the second box body 20222 to achieve the angle adjustment of the photovoltaic component 19. At the same time, the second screw structure is also running, which will also drive the mounting plate 16 to move horizontally. At this time, the position of the tensioning pulley 14 has also changed, so that the transmission belt 15 can maintain its own state and will not be detached. This embodiment realizes the linkage effect of the two through a simple mechanism, effectively solving the problem of structural interference.

[0028] like Figure 1 As shown, another object of the present invention is to provide a photovoltaic device, comprising a plurality of photovoltaic components 19, wherein the photovoltaic components 19 are installed on the supporting mechanism for facilitating the installation of the photovoltaic components.

[0029] In one case of the present embodiment, the support mechanism utilizes the characteristic that most of the photovoltaic modules 19 are tilted to tilt the strip box 501. In the actual installation process, due to the lower height of the first vertical frame 102, the construction personnel first install a photovoltaic module 19 on the mounting blocks 503 on both sides. After the installation is completed, the driving member 4 can drive the transmission assembly to operate, so that the drag chain structure 502 of the strip box 501 rotates, and then the installed photovoltaic modules 19 are lifted to a higher place. In this way, the photovoltaic modules 19 installed at a low position are gradually lifted to a high position, which makes it more convenient for the construction personnel to carry or install the photovoltaic modules 19, thereby improving the overall installation efficiency. In addition, the support mechanism does not use a complex mechanism for driving and controlling, and the overall shape still maintains a similar appearance to the steel structure. On the basis of ensuring stability, it also meets the requirements for use in the field environment.
