[0032] Referring to the drawings Figures 1-6 A photovoltaic power generation assembly convenient for maintenance, each power generation unit comprises a support 1 and a solar cell panel 2 mounted on the support 1, characterized by further comprising:

[0033] A protective frame 3 is installed below the solar cell panel 2.

[0034] A plurality of connecting seats 4 are arranged at the bottom of the protective frame 3; an avoiding hole 5 is formed in the side wall of the connecting seat 4, and a limiting piece 6 is arranged in the avoiding hole 5; the limiting piece 6 partially shields the avoiding hole 5.

[0035] A plurality of fixing seats 7 are arranged above the support 1 and correspond to the positions of the connecting seats 4; the fixing seat 7 is integrally provided with a limiting column one 8 and a limiting column two 9, the outer diameter of the limiting column one 8 is smaller than the outer diameter of the limiting column two 9; a clamping joint 10 is arranged at the front end of the limiting column one 8, the clamping joint 10 passes through the avoiding hole 5 and is clamped with the limiting piece 6; a chamfer is formed at the front end of the clamping joint 10, which facilitates passing through the limiting groove 18; an accommodating groove 11 is formed on the side of the clamping joint 10 facing the limiting column two 9, so that the front end of the movable ring 13 can enter the accommodating groove 11; a handle 12 is arranged at the end of the limiting column two 9 away from the limiting column one 8, and pressing the handle 12 can drive the limiting column two 9 and the limiting column one 8 to move towards the connecting seat 4; a threaded groove is formed at the front end of the limiting column one 8, and an avoiding groove 23 is formed in the middle of the clamping joint 10; the avoiding groove 23 is penetrated by a locking bolt 24, and the locking bolt 24 is threadedly connected with the threaded groove, so that the clamping joint 10 can be locked on the limiting column one 8.

[0036] A movable ring 13 is sleeved on the limiting column one 8, the middle part of the movable ring 13 is protruded, and both ends are arranged as inclined surfaces, which facilitates extruding the limiting groove 18; the outer diameter of the middle part of the movable ring 13 is larger than the outer diameter of the clamping joint 10.

[0037] The elastic assembly is located inside the fixed seat 7 and is used to drive the clamping joint 10 to return; the elastic assembly includes an elastic plate 14 and a compression spring 15, and the elastic plate 14 and the compression spring 15 are sleeved on the limiting column 9; the elastic plate 14 is in threaded cooperation with the limiting column 9, so that the elastic plate 14 can be driven to return together with the compression spring 15 while adjusting the length of the limiting column 9 extending out of the fixed seat 7.

[0038] In the embodiment, the limiting member 6 includes a limiting plate 16 and a guide screw 17; the limiting plate 16 partially covers the avoiding hole 5 and is provided with a limiting groove 18 for clamping the clamping joint 10, and the top and bottom of the limiting plate 16 are provided with two symmetrical guide plates 19; the guide screw 17 penetrates through the front and rear wall plates of the connecting seat 4 and the guide plates 19 and is locked by a nut, so that the guide screw 17 is convenient to disassemble and assemble; the compression spring 20 is sleeved on the guide screw 17, one end of the compression spring 20 abuts against the guide plate 19, and the other end abuts against the inner side of the rear wall plate of the connecting seat 4.

[0039] When it is needed to lock the solar cell panel 2 on the support 1, the staff needs to press the handle 12 to drive the limiting column 9 and the limiting column 8 to move and drive the clamping joint 10 to pass through the avoiding hole 5 and contact the limiting plate 16; since the clamping joint 10 is provided with a chamfer, the staff continues to press the handle 12 to drive the clamping joint 10 to slowly pass through the limiting groove 18 provided on the limiting plate 16 until the clamping joint 10 completely passes through the limiting groove 18. In the process that the clamping joint 10 passes through the limiting groove 18, the limiting plate 16 slides along the guide screw 17 and simultaneously extrudes the compression spring 20; after the clamping joint 10 completely passes through the limiting groove 18, the guide plate 19 on the limiting plate 16 is driven to return to the initial position along the guide screw 17 under the elastic force of the compression spring 20, so that the limiting plate 16 is clamped with the clamping joint 10 to prevent the clamping joint 10 from returning. At this time, the connecting seat 4 and the fixed seat 7 are in a locked state, so that the solar cell panel 2 can be placed stably on the support 1. It needs to be noted that since the outer diameter of the middle convex part of the movable ring 13 sleeved on the limiting column 8 is greater than the outer diameter of the clamping joint 10, the movable ring 13 is blocked at the avoiding hole 5 when the clamping joint 10 passes through the limiting groove 18 and cannot pass through the limiting groove 18 together with the clamping joint 10.

[0040] When it is needed to dismount the solar panel 2 from the support 1, the staff can press the handle 12 again to push the limiting column two 9 and the limiting column one 8 to continue moving towards the avoiding hole 5. Since the inner diameter of the movable ring 13 is smaller than the outer diameter of the limiting column two 9, when the limiting column two 9 is continuously pushed, the movable ring 13 is pushed to pass through the limiting groove 18. When the movable ring 13 completely passes through the limiting groove 18, it is blocked by the limiting plate 16 from returning. At this time, the staff stops pressing the handle 12, and the rebound plate 14 drives the limiting column two 9 and the limiting column one 8 to return under the elastic force of the compression spring one 15, and can drive the clamping joint 10 to return. In the process of returning of the clamping joint 10, the clamping joint 10 is in contact with the movable ring 13, so that one side of the movable ring 13 enters the containing groove 11, and the movable ring 13 is driven to return together. In the process of returning of the movable ring 13, the limiting groove 18 is slowly expanded, so that the clamping joint 10 is not blocked by the limiting plate 16 in the returning process. When the clamping joint 10 passes through the limiting groove 18 and the avoiding hole 5 smoothly, under the elastic force of the compression spring two 20, the clamping joint 10 returns to the initial state until the side of the rebound plate 14 away from the compression spring one 15 is in contact with the side wall of the fixed seat 7.

[0041] On the other hand, the fixed seat 7 is provided with two symmetrical baffles 21 on the side facing the connecting seat 4, and the limiting column one 8 is located between the two baffles 21. The connecting seat 4 is provided with a positioning plate 22 on each side at the top, and the positioning plate 22 is fixed to the bottom of the protective frame 3 through bolts; the positioning plate 22 close to the fixed seat 7 is located between the two baffles 21, and can play an auxiliary positioning role in the installation process, and can quickly align the connecting seat 4 and the fixed seat 7 at the corresponding position.

[0042] The photovoltaic power generation assembly convenient to overhaul of the utility model, through setting up multiple mutually locking and matching connecting seats 4 and fixed seats 7, can realize quick locking or dismounting of the support 1 and the solar photovoltaic panel, and can avoid damaging the support 1 and the photovoltaic power generation assembly frame in the dismounting process, is favorable to improving the overhaul efficiency, is very practical, has better market application prospect.
