[0035] like Figure 2 , 3As shown in Figure 5, according to an optional embodiment of the present invention, the support plate 30 is slidably connected to the inner wall of the transmission cavity 9, a plate cavity 36 is provided on the connector 8, a driven rack 31 is fixedly connected to the bottom wall of the support plate 30, the top wall of the plate cavity 36 is connected to the bottom wall of the transmission cavity 9 through two connecting channels 38, the lower end of the driven rack 31 passes through one of the connecting channels 38 and extends into the plate cavity 36, the inner wall of the plate cavity 36 is slidably connected to a transmission plate 34, and an active gear is fixedly connected to the transmission plate 34.

The wedge block 37 and the bottom wall of the blocking plate 24 are against each other, and the inclined surface of the wedge block 37 faces the direction of the cable entry channel 10.

[0036] like Figure 1-4 As shown in 7, according to an optional embodiment of the present invention, the inner wall of the transmission cavity 9 is slidably connected to two slides 13, the wheel axle 12 is rotatably connected to the two slides 13, the inner wall of the transmission cavity 9 is fixedly connected to two first limit blocks 14 and two second limit blocks 15, the slides 13 and the first limit blocks 14 are abutted against each other, and the bottom wall of the second limit blocks 15 is fixedly connected to a puncture needle 16, a loader 17 is fixedly connected to the slide 13, a loading cavity 18 is defined on the loader 17, a puncture channel 19 is defined on the loader 17 and passes through the top wall and the bottom wall of the loader 17, the puncture channel 19 is communicated with the loading cavity 18, a packaging body 20 is placed on the inner wall of the loading cavity 18, and the packaging body 20 is filled with lubricating oil 21.

[0037] like Figure 2 , 3 6, according to an optional embodiment of the present invention, the air pipe 27 is fixedly connected with a deflation valve 39, the deflation valve 39 is rotatably connected with a valve control shaft 40, the valve control shaft 40 is rotatably connected to the connector 8, one end of the valve control shaft 40 extends to the outside of the connector 8, the second gear 41 is fixedly connected to the end of the valve control shaft 40 located outside the connector 8, the photovoltaic panel 7 is slidably connected with a control member 43, the control member 43 is fixedly connected with more than two external racks 42, the number of external racks 42 is the same as the number of the connector 8, the external racks 42 are slidably connected to the connector 8, and the external racks 42 are meshed with the second gear 41. The movement of the control member 43 can control the movement of all the external racks 42 connected thereto, thereby driving the second gear 41 to rotate.

[0038] like Figure 2 , 3As shown, in an alternative embodiment of the present invention, a pressure roller 23 is rotatably connected to the eccentric rod 22, which can reduce the friction when the eccentric rod 22 abuts against the inflatable ball 28.

[0039] As Figure 2 , 3 shown, in an alternative embodiment of the present invention, the tip of the lancet 16 faces the puncture channel 19, so that the lancet 16 can enter the puncture channel 19.

[0040] As Figure 2 , 3 shown, in an alternative embodiment of the present invention, a limiting plate 44 is fixedly connected to the inner wall of the transmission cavity 9.

[0041] As Figure 2 , 3 shown, in an alternative embodiment of the present invention, a guide rail 45 is fixedly connected to the inner wall of the transmission cavity 9, and the blocking plate 24 is slidably connected to the guide rail 45.

[0042] As Figure 4 shown, in an alternative embodiment of the present invention, the control member 43 is in a U shape.

[0043] As Figure 1 shown, in an alternative embodiment of the present invention, a roof decoration member is connected to the top wall of the building body 1. The roof decoration member not only makes the building body 1 more unique and full of design sense, but also can block strong sunlight, reduce the direct exposure to the roof, play a role in sun protection and temperature reduction, and prevent excessive rain from directly washing the roof and the outer wall. A building south exterior wall photovoltaic power generation system 3 is connected to the south exterior wall of the building body 1, a building east exterior wall photovoltaic power generation system 4 is connected to the east exterior wall of the building body 1, and a building west exterior wall photovoltaic power generation system 5 is connected to the west exterior wall of the building body 1.

[0044] Connection process of the connector 8 and the cable 6:

[0045] In the initial state, the airbag 25 is in a deflated state, the blocking plate 24 does not abut against the right wall of the transmission cavity 9, and the sliding seat 13 abuts against the first limiting block 14.

[0046] The cable 6 enters the transmission chamber 9 from the cable entry channel 10 and abuts against the roller 11. The cable 6 supports the roller 11. Under the gravity of the photovoltaic panel 7 and the connector 8, the axle 12 and the slide 13 move up along the inner wall of the transmission chamber 9 until the slide 13 and the bottom wall of the second limit block 15 abut against each other. The slide 13 drives the loader 17 to move up at the same time, so that the needle 16 passes through the puncture channel 19 and is inserted into the loading chamber 18. The needle 16 pierces the packaging body 20, so that the lubricating oil 21 in the packaging body 20 passes through the puncture channel 19 and flows between the slide 13 and the axle 12 to lubricate the two, so that the axle 12 can rotate more smoothly on the slide 13, so that the constructor can push the connector 8 more easily.

[0047] The constructor pushes the photovoltaic panel 7 to make the roller 11 rotate on the cable 6. The roller 11 drives the axle 12, the eccentric rod 22 and the pressure roller 23 to rotate. The pressure roller 23 flattens the inflatable ball 28 for many times. The inflatable ball 28 enters the air through the one-way valve 29, and then transmits the air to the airbag 25 through the air pipe 27, so that the airbag 25 expands, thereby pushing the blocking plate 24 to move right along the guide rail 45 until it abuts against the right wall of the transmission chamber 9, limiting the cable 6 to prevent the cable 6 from leaving the transmission chamber 9. When the blocking plate 24 abuts against the right wall of the transmission chamber 9, it just moves to the right of the wedge block 37 , the wedge block 37 loses the obstruction of the bottom wall of the blocking plate 24, and the active rack 33, the transmission plate 34, and the wedge block 37 move up under the elastic force of the elastic member 35, and the active rack 33 drives the steering gear 32 to rotate counterclockwise, and the steering gear 32 drives the driven rack 31 to move down, thereby moving the support plate 30 and the inflatable ball 28 down. The constructor continues to push the photovoltaic panel 7 so that even if the roller 11 continues to rotate, the pressure roller 23 will not flatten the inflatable ball 28, that is, stop inflating the airbag 25 to keep the blocking plate 24 in the current position, completing the connection limit of the cable 6 and the connector 8.

[0048] When the photovoltaic panel 7 needs to be inspected and the connector 8 and the cable 6 need to be disconnected in the future, it is only necessary to slide the control member 43 on the photovoltaic panel 7, thereby driving all the external racks 42 to slide on each connector 8, and the external racks 42 drive the second gear 41 to rotate, so that the valve control shaft 40 rotates to control the deflation valve 39 to deflate, thereby shrinking the airbag 25, driving the blocking plate 24 to move left and reset, releasing the limit on the cable 6, and releasing the connection between the connector 8 and the cable 6. The blocking plate 24 will push the inclined surface of the wedge block 37 to move it downward, thereby moving the inflatable ball 28 upward to facilitate the subsequent movement of the blocking plate 24, so that the connector 8 and the cable 6 can be connected again.

[0049] The connection construction method of other components of the flexible bracket is realized by using the existing technology and will not be described here.

[0050] This embodiment can conveniently connect the connector 8 and the cable 6 without the need for external tools such as screwdrivers and screws as in the prior art. When pushing the photovoltaic panel 7, the blocking plate 24 can automatically limit the position of the cable 6, and the blocking plate 24 automatically stops moving after moving to the set distance, which will not affect the constructor's continued pushing of the photovoltaic panel 7, and can automatically add lubricating oil 21 to the rotating connection between the slide seat 13 and the axle 12, so that the constructor can push the photovoltaic panel 7 more labor-saving, improve construction comfort, and improve construction efficiency and construction quality.

[0051] The components, modules, mechanisms and devices not described in detail in the present invention are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
