[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy.

Through the cooperation of the U-shaped plate 6, the synchronization rod 7, the guide cover 8 and the auxiliary rod 9, when the connector 22 and the connecting socket 32 ​​are about to be plugged in, the bottom of the plug rod 21 contacts the synchronization ring 71, and the synchronization ring 71 drives the synchronization rod 7 to slide, and the synchronization rod 7 drives the entire sliding sleeve 621 to slide on the limit rod 62, and drives the U-shaped plate 6 to start moving through the swing arm 623, and then the U-shaped plate 6 blocks the inner connection between the plug rod 21 and the socket 31, further improving the sealing performance, and in the process of sliding the sleeve 621, the position of the guide cover 8 on the side wall of the sleeve 621 changes synchronously, and the inclined surface 81 on the guide cover 8 drives the auxiliary rod 9 to move toward the center, and the end of the auxiliary rod 9 pushes the inserted plug rod 21 to move, which achieves the purpose of fine-tuning the position of the plug rod 21, ensuring that the connector 22 at the end of the plug rod 21 is smoothly plugged into the connecting socket 32, making installation easier.

[0055] like Figures 1 to 7 As shown, in a specific embodiment, a sealing plate 211 is installed at the connection between the plug rod 21 and the fixed plate 2. The diameter of the sealing plate 211 is larger than the diameter of the plug rod 21. The sealing plate 211 has a sealing effect. The length of the plug rod 21 and the width of the inner cavity of the plug cover 3 are adapted to each other to ensure that the connector 22 at the end of the plug rod 21 can be plugged into the connecting socket 32 ​​inside the plug cover 3.

[0056] like Figures 1 to 7As shown, further, the card plate 4 is in a vertical state, a rotating shaft 41 is installed at the rotating center of the card plate 4, a mounting opening 412 is provided on the side wall of the plug cover 3, both ends of the rotating shaft 41 are installed on the side wall of the mounting opening 412, and a torsion spring 411 is sleeved on the rotating shaft 41, one end of the torsion spring 411 is clamped on the side wall of the mounting opening 412, and the other end of the torsion spring 411 is clamped on the card plate 4. In the process of the card plate 4 being pushed open, the card plate 4 rotates as a whole, the rotating shaft 41 on the card plate 4 rotates on the mounting opening 412 at this time, and the torsion spring 411 on the rotating shaft 41 is twisted synchronously, and the torsion spring 411 is convenient for the later reset operation through the torsion spring 411. When the rotating shaft 41 rotates, the rotating shaft 41 drives the rocker 42 to rotate.

[0057] Example 2, reference Figure 1 to Figure 7 , which is the second embodiment of the present invention, is different from the previous embodiment in that a mounting cover 51 is welded on the sealing cover 5, a mounting groove 512 is provided inside the mounting cover 51, and a slide bar 511 is installed inside the mounting groove 512, the rocker arm 42 slides inside the mounting groove 512, and a strip groove 421 is provided on the surface of the rocker arm 42, and the slide bar 511 is slidably arranged in the strip groove 421. During the rotation of the rocker arm 42, the position of the strip groove 421 inside the rocker arm 42 changes, and a slide bar 511 is slidably arranged inside the strip groove 421, and the slide bar 511 and the mounting cover 51 inside the sealing cover 5 are connected to each other, so that the rocker arm 42 can drive the sealing cover 5 to slide, and at this time, the sealing cover 5 covers the fixing plate 2 as a whole, thereby achieving a sealing effect on the outer wall of the plug rod 21 and the plug cover 3.

[0058] like Figures 1 to 7 As shown, in a specific embodiment, a fixing seat 522 is installed on the plug cover 3, a reset cover 52 is installed on the side wall of the fixing seat 522, a baffle 523 is slidably installed inside the reset cover 52, a reset rod 521 is installed on the side wall of the baffle 523, the reset rod 521 movably penetrates the side wall of the reset cover 52, and a reset spring 524 is sleeved on the reset rod 521 located on the inner wall of the reset cover 52, one end of the reset spring 524 is clamped on the baffle 523, and the other end is clamped on the inner wall of the reset cover 52, a top plate 525 is installed at the end of the reset rod 521, and the top plate 525 is installed on the surface of the installation cover 51. When the installation cover 51 and the sealing cover 5 slide, the top plate 525 on the side wall of the sealing cover 5 drives the reset rod 521 and the baffle 523 to slide inside the reset cover 52, and the baffle 523 compresses the reset spring 524 at this time, and the reset operation is facilitated by the reset spring 524 in the later stage.

[0059] like Figures 1 to 7As shown, further, a sealing gasket 61 is installed on the inner side wall of the U-shaped plate 6, and a pair of guide rails 611 are slidably installed on the back of the U-shaped plate 6, and the pair of guide rails 611 are welded and arranged on the inner side wall of the plug cover 3. It is ensured that the sealing gasket 61 on the U-shaped plate 6 moves along the guide rails 611 as a whole, and the inner connection between the plug rod 21 and the plug hole 31 is blocked to improve the sealing performance.

[0060] Example 3, reference Figure 1 to Figure 7 , which is the third embodiment of the present invention. Different from the previous embodiment, blocking plates 622 are installed at both ends of the sliding sleeve 621, one of the blocking plates 622 is rotatably connected to the swing arm 623, and the swing arm 623 is in an inclined state, and the other blocking plate 622 is connected to the synchronization rod 7. Two extrusion springs 624 are sleeved on the limit rod 62, and the two extrusion springs 624 are respectively placed at both ends of the limit rod 62, and one end of the extrusion spring 624 is clamped on the side wall of the plug cover 3, and the other end of the extrusion spring 624 is clamped on the side wall of the blocking plate 622. When the connector 22 and the connector socket 32 ​​are about to be plugged together, the bottom of the plug rod 21 is in contact with the synchronization ring 71, and the connector 22 can pass through the center to ensure that the connector 22 can be connected to the connector socket 32, and the plug rod 21 can also squeeze the synchronization ring 71 to slide. At this time, the synchronization ring 71 can drive the synchronization rod 7 to slide, and the synchronization rod 7 drives the entire sleeve 621 to slide on the limit rod 62. During the sliding process, the blocking plate 622 on the side wall of the sleeve 621 can move synchronously, and the blocking plate 622 can compress the reset spring 524, so that the reset operation can be performed later through the reset spring 524.

[0061] like Figures 1 to 7As shown, in a specific embodiment, the surface of the synchronization ring 71 corresponds to the surface of the plug rod 21, and the size of the hollow circle in the center of the synchronization ring 71 matches the size of the connector 22. The height of the inclined surface 81 close to one side of the U-shaped plate 6 is higher than the height of the other side, and the plane 82 is connected to the end surface of the highest point of the inclined surface 81. A limited seat 931 is installed inside the plug cover 3, and an auxiliary rod 9 is inserted inside the limited seat 931. A guide wheel 92 is installed at one end of the auxiliary rod 9, and the guide wheel 92 is connected to the guide cover 8.

A limited spring 932 is sleeved on the auxiliary rod 9 between the limited seat 931 and the pressure plate 93. One end of the limited spring 932 is clamped on the pressure plate 93, and the other end is clamped on the limited seat 931. The auxiliary plate 91 at the end of the auxiliary rod 9 is pushed toward the inserted plug 21 to move, thereby ensuring that the plug 21 is inserted in the center position of the socket 31, and the position of the connector 22 on the plug 21 can also be adjusted, thereby achieving the purpose of fine-tuning the position of the plug 21, ensuring that the connector 22 at the end of the plug 21 is smoothly inserted into the connecting socket 32, making the installation easier.

[0062] The implementation principle of an expandable photovoltaic power generation assembly of this embodiment is as follows:

[0063] When two photovoltaic panels 1 are plugged in and assembled, the plug rod 21 on the fixing plate 2 first moves toward the plug hole 31 on the surface of the plug cover 3, wherein the plug hole 31 is provided with a card board 4, which can ensure the dryness of the inside of the plug cover 3 and prevent water from entering the electronic components inside the plug cover 3. When the plug rod 21 and the plug hole 31 are plugged in, the plug rod 21 can push the card board 4 open as a whole, and the connector 22 at the end of the plug rod 21 can be smoothly plugged in the connection socket 32, and finally the purpose of installation can be achieved.

[0064] In the process of the card plate 4 being pushed open, the card plate 4 rotates as a whole, and the rotating shaft 41 on the card plate 4 rotates on the installation port 412 at this time, and the torsion spring 411 on the rotating shaft 41 is twisted synchronously, and the torsion spring 411 is used to facilitate the later reset operation. When the rotating shaft 41 rotates, the rotating shaft 41 drives the rocker arm 42 to rotate. The strip groove 421 inside the rocker arm 42 is provided with a sliding rod 511 for sliding inside, and the sliding rod 511 and the installation cover 51 inside the sealing cover 5 are connected to each other, so that the rocker arm 42 can drive the sealing cover 5 to slide, and the sealing cover 5 covers the fixed plate 2 as a whole, thereby sealing the outer wall of the plug rod 21 and the plug cover 3. And when the installation cover 51 and the sealing cover 5 slide, the top plate 525 of the side wall of the sealing cover 5 drives the reset rod 521 and the baffle 523 to slide inside the reset cover 52, and the baffle 523 compresses the reset spring 524 at this time, and the reset operation is facilitated by the reset spring 524.

[0065] When the card plate 4 is pushed open, the card plate 4 is in a tilted state, and the tilted card plate 4 can be engaged with the card slot 212, so that the insertion rod 21 and the insertion cover 3 are tightly connected together. At this time, the connector 22 and the connecting socket 32 ​​are plugged into each other, thereby ensuring the stability of the connection.

[0066] When the connector 22 and the connecting socket 32 ​​are about to be plugged in, the bottom of the plug rod 21 contacts the synchronous ring 71, and the connector 22 can pass through the center to ensure that the connector 22 can be connected to the connecting socket 32, and the plug rod 21 can also squeeze the synchronous ring 71 to slide. At this time, the synchronous ring 71 can drive the synchronous rod 7 to slide, and the synchronous rod 7 drives the entire sliding sleeve 621 to slide on the limit rod 62. During the sliding process, the blocking plate 622 on the side wall of the sliding sleeve 621 can move synchronously, and the blocking plate 622 can compress the reset spring 524, and the reset spring 524 is used to facilitate the later reset operation. When the blocking plate 622 slides, the swing arm 623 on the blocking plate 622 drives the U-shaped plate 6 to start moving, and the sealing gasket 61 on the U-shaped plate 6 moves along the guide rail 611 as a whole. Finally, the U-shaped plate 6 and the sealing gasket 61 can seal the inner connection between the plug rod 21 and the socket 31, thereby further improving the sealing performance.
