[0002] At present, with the vigorous development of clean energy, floating photovoltaic power stations have been widely used due to their many advantages. Among them, the fixed structure of floating photovoltaic modules is crucial, which bears the heavy responsibility of firmly supporting the photovoltaic panels to enable them to efficiently receive solar energy.

[0003] Currently, the installation of floating photovoltaic modules usually requires first fixing anchor piles in the water, then installing fixed brackets on the anchor piles, and finally fixing the photovoltaic panels on two adjacent fixed brackets through bolts. However, this installation method has obvious deficiencies: Firstly, when it is necessary to finely adjust the installation angle of the photovoltaic panels, the staff needs to turn multiple bolts for adjustment, which is cumbersome and time-consuming, reducing the installation efficiency; Secondly, the photovoltaic panels are only connected to the fixed brackets through bolts, and are prone to insufficient stability due to wind and wave impacts or bolt loosening during long-term use, and even shaking or falling may occur, which will affect the normal use of the photovoltaic modules.

Detailed implementation manners

[0032] The following will further elaborate on the present application in conjunction with the attached Figure 1 - Figure 10 drawings.

[0033] Please refer to Figure 1 , a fixed structure for a floating photovoltaic module, comprising two anchor piles 1. A height adjustment assembly 2 for adjusting the height of the photovoltaic panel 13 and an angle adjustment assembly 3 for adjusting the angle of the photovoltaic panel 13 are provided on the anchor piles 1. A fixing plate 12 is commonly arranged between the corresponding height adjustment assembly 2 and angle adjustment assembly 3.

[0034] Refer to Figure 2 , Figure 3 and Figure 4 , the height adjustment assembly 2 includes a mounting plate 21 fixedly arranged at the upper end of the anchor pile 1 by bolts. A threaded sleeve 22 is fixedly arranged on the upper part of the mounting plate 21. A threaded rod 23 is threadedly arranged inside the threaded sleeve 22. The top end of the threaded rod 23 penetrates out of the threaded sleeve 22 and is hinged to the bottom of the fixing plate 12.

[0035] In order to ensure that multiple groups of photovoltaic panels 13 are at the same height after installation, before installing the mounting plate 21 on the upper part of the anchor pile 1 through bolts, the staff holds the threaded rod 23 and then rotates the threaded sleeve 22. When the threaded sleeve 22 rotates, it can drive the mounting plate 21 to rotate and move up or down at the same time, so that the distance between the mounting plate 21 and the fixed plate 12 can be adjusted according to the predetermined installation height of the photovoltaic panels 13. Then, after installing the mounting plate 21 on the upper part of the anchor pile 1 through bolts, it can ensure that multiple groups of photovoltaic panels 13 are at the same height after installation.

[0036] Refer to Figure 2 , Figure 3 and Figure 5 , the angle adjustment assembly 3 includes a clamp 31 arranged outside the anchor pile 1 through bolts. On the side of each of the two clamps 31 away from each other, two support rods 32 symmetrically distributed front and back are hingedly arranged, and the lengths of the two support rods 32 are different. One end of the support rod 32 away from the clamp 31 is hingedly provided with a moving block 33.

[0037] Refer to Figure 6 , a groove is formed inside the moving block 33. A first reset spring 331 is fixedly arranged in the groove. The bottom end of the first reset spring 331 is fixedly provided with an arc-shaped block 332. The bottom end of the arc-shaped block 332 penetrates out of the groove. One side of the arc-shaped block 332 is fixedly provided with an L-shaped plate 333, and the side of the L-shaped plate 333 away from the arc-shaped block 332 penetrates out of the groove.

[0038] Refer to Figure 2 and Figure 5 , a U-shaped plate 7 is fixedly arranged at the bottom of the fixed plate 12. The moving block 33 is located inside the U-shaped plate 7 and is slidably connected to the U-shaped plate 7. A plurality of arc-shaped openings 8 are formed on the front and back sides of the horizontal section inside the U-shaped plate 7, and the bottom end of the arc-shaped block 332 is clamped with the corresponding arc-shaped opening 8. A rectangular opening 11 for the threaded rod 23 to pass through is formed on the horizontal section of the U-shaped plate 7, and a sponge is arranged on the inner wall of the rectangular opening 11.

[0039] In order to facilitate the adjustment of the installation angle of the photovoltaic panel 13, when it is necessary to adjust the installation angle of the photovoltaic panel 13, the staff can pull the corresponding two L-shaped plates 333 to drive the corresponding two arc-shaped blocks 332 to move upward. When the arc-shaped blocks 332 move upward and away from the corresponding arc-shaped openings 8, the first reset spring 331 will also be squeezed. At this time, the limit locking of the moving block 33 is cancelled. Then, the corresponding two moving blocks 33 can be slid to drive the corresponding support rods 32 to rotate. By rotating the two support rods 32, the fixed plate 12 can be rotated to the required angle. When the fixed plate 12 rotates, the sponge makes it not easy to friction the threaded rod 23. Then, release the L-shaped plate 333. Through the cooperation of the first reset spring 331, the arc-shaped block 332 can be driven to insert into the corresponding arc-shaped opening 8 to continue to lock the slider 61, so that the installation angle of the photovoltaic panel 13 can be conveniently adjusted.

[0040] Refer to Figure 1 and Figure 2 , on the side where the two fixed plates 12 are close to each other, a support plate 4 for supporting the photovoltaic panel 13 is fixedly arranged, and on the side where the two fixed plates 12 are close to each other, a second limiting component 6 is arranged to cooperate with the support plate 4 to limit the photovoltaic panel 13 between the two support plates 4.

[0041] Refer to Figure 3 , Figure 7 and Figure 8 , on the side where the two fixed plates 12 are close to each other, a storage groove 9 is opened. The second limiting component 6 includes a slider 61 slidably arranged inside the storage groove 9. A baffle 62 is rotatably arranged on the upper part of the slider 61. The sides where the two baffles 62 are close to each other are respectively in contact with the front and rear sides of the photovoltaic panel 13, and the baffle 62 is located between the two storage grooves 9.

[0042] Refer to Figure 8 , two locking grooves 621 are opened on the upper part of the baffle 62. A third reset spring 622 is fixedly arranged in the locking groove 621. A locking rod 623 is fixedly arranged on the upper part of the third reset spring 622, and the sides where the corresponding two locking rods 623 are close to each other are both in a slope shape. A plurality of locking openings 10 communicating with the storage groove 9 and cooperating with the locking rod 623 are opened on the upper part of the fixed plate 12. The end of the locking rod 623 away from the third reset spring 622 penetrates out of the locking groove 621 and passes through the corresponding locking opening 10.

[0043] In order to improve the stability of the photovoltaic panel 13 after installation, after adjusting the use angle and use height of the fixed plate 12, the staff can rotate the baffle 62 in the storage groove 9 to move it out of the corresponding storage groove 9 (such as Figure 7As shown in the figure), then continue to rotate the baffle 62 so that the side of the baffle 62 away from the slider 61 approaches another storage groove 9. At this time, the staff can press the locking rod 623 removed from the storage groove 9, so that the side of the baffle 62 away from the slider 61 can be smoothly rotated into another storage groove 9. At this time, the corresponding locking rod 623 is inserted into the corresponding locking port 10 on another fixing plate 12 (as Figure 3 shown), so that the two fixing plates 12 can be tightly connected together by the two baffles 62. Then, according to the size of the photovoltaic panel 13, the baffle 62 can be pushed to move so that the locking rod 623 is inserted into the corresponding locking port 10. Then, when installing the photovoltaic panel 13, the photovoltaic panel 13 can be installed on the upper parts of the two supporting plates 4 through bolts. At this time, the left and right sides of the photovoltaic panel 13 can be limited by the two fixing plates 12, and the front and back sides of the photovoltaic panel 13 can be limited by the two baffles 62. Through this multi-directional limiting effect, the photovoltaic panel 13 is stably fixed at a predetermined position, and can remain stable even in the face of a complex water environment, such as the impact of wind and waves and the surging of water flow, thereby further ensuring the stability of the photovoltaic panel 13 after installation.

[0044] Refer to Figure 2 , Figure 5 and Figure 9 , a first limiting component 5 for cooperating with the photovoltaic panel 13 to limit the angle adjustment component 3 is arranged on the supporting plate 4. The photovoltaic panel 13 is connected to the supporting plate 4 through bolts, and the bottom of the photovoltaic panel 13 contacts the upper part of the supporting plate 4. A rectangular groove is opened in the upper part of the supporting plate 4. The first limiting component 5 includes two connecting blocks 51 which are slidably arranged in the rectangular groove and are L-shaped. A moving plate 52 is fixedly arranged on the upper parts of the two connecting blocks 51. The moving plate 52 is located in the rectangular groove and abuts against the bottom of the photovoltaic panel 13. A limiting plate 53 is fixedly arranged on the side of the two connecting blocks 51 away from the moving plate 52. The bottom of the limiting plate 53 contacts the upper part of the L-shaped plate 333. Two second return springs 54 are arranged on the upper part of the limiting plate 53. The top ends of the second return springs 54 are connected to the bottom of the supporting plate 4.

[0045] In order to further ensure the stability of the photovoltaic panel 13 during use, when the photovoltaic panel 13 is installed on the supporting plate 4, the photovoltaic panel 13 will contact the moving plate 52 and squeeze the moving plate 52. The moving plate 52 is squeezed and drives the limiting plate 53 to move downward through the connecting block 51, so that the limiting plate 53 moves downward to contact the upper part of the L-shaped plate 333. At this time, the L-shaped plate 333 is not likely to move due to external influences, making the photovoltaic panel 13 less likely to shake during use, thereby further ensuring the stability of the photovoltaic panel 13 during use.

[0046] During specific operation, when installing and fixing the photovoltaic panel 13, first use the height adjustment component 2 to adjust the use height of the fixing plate 12 according to the predetermined installation standard. Then fix the clamp 31 on the upper part of the anchor pile 1, and then use the angle adjustment component 3 to adjust the use angle of the fixing plate 12 according to the predetermined installation standard.

[0047] Then the staff can pull the two baffles 62 to rotate 90 degrees respectively, so that the two fixing plates 12 can be tightly connected together. At the same time, through the cooperation of the locking rod 623 and the locking port 10, the baffle 62 can be pushed to a suitable use position. After installing the photovoltaic panel 13 on the upper parts of the two supporting plates 4 through bolts, at this time, through the cooperation of the fixing plate 12 and the baffle 62, the photovoltaic panel 13 can be limited in multiple directions, and it can remain stable even in the face of a complex water environment, such as the impact of wind and waves and the surging of water flow, thus further ensuring the stability of the photovoltaic panel 13 after installation.

[0048] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
