[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the self-locking anti-detachment photovoltaic module array mechanism adopts a new structural design, so that the photovoltaic panel can be quickly locked on the array structure, with high working efficiency, and a structure for rapid expansion and contraction of the photovoltaic panel is also provided, which improves the flexibility of using the photovoltaic panel, and in the process of rapid expansion and contraction of the photovoltaic panel, the nozzle will work, and the nozzle will blow out gas, so that the dust on the surface of the photovoltaic panel is quickly blown away, which is convenient for the subsequent cleaning work of the staff. The specific contents are as follows: (1) When the self-locking anti-detachment photovoltaic module array mechanism is used, when the photovoltaic panel needs to be docked to the outer frame, the photovoltaic panel of suitable size is directly placed in the placement groove. At this time, the lower surface of the photovoltaic panel will push the cross bar, so that the cross bar and the limit block move in the direction of squeezing the connecting spring. After the photovoltaic panel enters the placement groove, the cross bar and the limit block return to their original position under the action of the connecting spring. At this time, the cross bar presses the photovoltaic panel, which plays a self-locking role, and the installation process is quick and convenient. Furthermore, when the photovoltaic panel enters the placement groove, the force block will be pushed by the photovoltaic panel. At this time, the force block moves in the direction of squeezing the connecting spring, and then the force block has a tendency to move to the outside of the placement groove. When the photovoltaic panel needs to be taken out, the cross bar is pulled so that the end of the cross bar does not contact the photovoltaic panel. At this time, the force block pops out under the action of the connecting spring, and then the force block plays a role in assisting disassembly, thereby improving work efficiency. (2) The self-locking anti-detachment photovoltaic module array mechanism starts the motor on the surface of the vertical plate when the outer frame and photovoltaic panel need to be unfolded. When the motor is working, the movable plate moves to the right side of the bottom plate under the action of the long pin and the limit rod. At this time, the outer frame and photovoltaic panel will slowly unfold, and then the outer frame and photovoltaic panel will be put into use. The operation process is fast and convenient, and the work efficiency is high. (3) The self-locking anti-detachment photovoltaic module array mechanism, during the movement of the movable plate, the movable plate will drive the push plate to move synchronously, and then the push plate will intermittently contact the force-bearing plate. At this time, the force-bearing plate will make reciprocating linear motion in the horizontal direction under the thrust of the push plate and the elastic force of the auxiliary spring, and then the outer plate will intermittently squeeze the air storage bag. When the air storage bag is squeezed, the air storage bag supplies air to the nozzle through the No. 1 pipe, and when the air storage bag is not squeezed, the air storage bag expands back. At this time, the air storage bag takes in air through the No. 2 pipe, and the above process is repeated. The nozzle is in intermittent blowing, and the nozzle can clean the dust on the surface of the photovoltaic panel, playing a self-cleaning role, which is convenient for the subsequent operation of the staff; Furthermore, when the air bag is working, the first one-way valve and the second one-way valve direct the airflow from the air to the nozzle, thereby ensuring the working stability of the air bag and the nozzle, and the upper surface of the side panel is convex, and the side panel can protect the air bag.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0019] Embodiment 1: By setting the motor 3, the long pin 4 and the movable plate 5, the outer frame 8 can be quickly unfolded, such as Figure 1-Figure 2 as well as Figure 6 As shown: It includes a bottom plate 1 and an outer frame 8, the upper surface of the bottom plate 1 is fixedly connected with a vertical plate 2, and the outer wall of the vertical plate 2 is bolted with a motor 3, and the output end of the motor 3 is fixedly connected with a long pin 4, and the surface of the long pin 4 is movably connected with a movable plate 5, the outer frame 8 is rotatably arranged on the upper surface of the movable plate 5, and a transition plate 9 is movably arranged between the upper surfaces of adjacent outer frames 8, and a transition block 6 is movably connected between the lower surfaces of adjacent outer frames 8; A self-locking anti-detachment photovoltaic module array mechanism, further comprising: A self-locking component is arranged on the surface of the outer frame 8. The self-locking component uses elastic force and the gravity of the photovoltaic panel to position and lock the designated photovoltaic panel on the outer frame 8, and a placement groove 12 is provided on the surface of the outer frame 8; a side panel 18, the side panel 18 is fixedly connected to the upper surface of the bottom plate 1, and a cleaning component is provided on the surface of the side panel 18. The cleaning component removes dust electrostatically adsorbed on the photovoltaic panel regularly through circulating airflow.

[0020] The surface of the vertical plate 2 is fixedly connected to the limit rod 7, and the surface of the limit rod 7 is slidably provided with a movable plate 5, and the movable plate 5 is threadedly connected to the long pin 4. The transition plate 9 is an "I" shape when viewed from above, and a rolling ball 10 is rotatably provided on the lower surface of the transition block 6, and the transition block 6 is an inverted "U" shape when viewed from the right.

[0021] When the outer frame 8 and the photovoltaic panel need to be unfolded, the motor 3 on the surface of the vertical plate 2 is started. When the motor 3 is working, the movable plate 5 moves to the right side of the bottom plate 1 under the action of the long pin 4 and the limit rod 7. At this time, the outer frame 8 rotates inside the transition plate 9, and the outer frame 8 rotates on the upper surface of the transition block 6. Finally, the outer frame 8 and the photovoltaic panel will slowly unfold, and then the outer frame 8 and the photovoltaic panel will be put into use. The operation process is quick and convenient, and the work efficiency is high.

[0022] Embodiment 2: Different from Embodiment 1, the upper connecting plate 13 and the cross bar 14 can be provided to quickly lock the photovoltaic panel when it is installed. Figure 3-Figure 5 As shown: The self-locking component includes an upper connecting plate 13 fixedly connected to the upper surface of the outer frame 8, and the upper connecting plate 13 is symmetrically distributed about the center of the outer frame 8, and a cross bar 14 is slidably arranged inside the upper connecting plate 13, both ends of the cross bar 14 are located on the outside of the upper connecting plate 13, and the end of the cross bar 14 is inclined, and the upper surface of the cross bar 14 is fixedly connected to a limiting block 15, and the upper surface of the cross bar 14 is concave.

[0023] A connecting spring 16 that plays an elastic reset role is fixedly connected to the surface of the limit block 15, and the other side of the connecting spring 16 is fixedly connected to the inner wall of the upper connecting plate 13. A force block 11 is slidably arranged inside the outer frame 8.

[0024] When the photovoltaic panel needs to be connected to the outer frame 8, the photovoltaic panel of suitable size is directly placed in the placement groove 12. At this time, the lower surface of the photovoltaic panel will push the cross bar 14, so that the cross bar 14 and the limit block 15 slide inside the upper connecting plate 13. At this time, the limit block 15 moves in the direction of squeezing the connecting spring 16. After the photovoltaic panel enters the placement groove 12, the cross bar 14 and the limit block 15 return to their original position under the action of the connecting spring 16. At this time, the cross bar 14 presses the photovoltaic panel and plays a self-locking role. The installation process is quick and convenient. In the process of the photovoltaic panel entering the placement groove 12, the force block 11 will be pushed by the photovoltaic panel. At this time, the force block 11 moves in the direction of squeezing the connecting spring 16, and then the force block 11 has a tendency to move to the outside of the placement groove 12. When the photovoltaic panel needs to be removed, the cross bar 14 is pulled so that the end of the cross bar 14 does not contact the photovoltaic panel. At this time, the force block 11 pops out under the action of the connecting spring 16, and then the force block 11 plays a role of auxiliary disassembly, thereby improving work efficiency.

[0025] Embodiment 3: Different from Embodiment 2, the dust on the surface of the photovoltaic panel can be quickly cleaned by setting a cleaning component, which is convenient for subsequent operations of the staff. Figure 7-Figure 9 As shown: The cleaning assembly includes a push plate 22 fixedly connected to the inner side of the movable plate 5, and the cleaning assembly also includes a force-bearing plate 23 slidably arranged inside the side plate 18, and the surface of the force-bearing plate 23 and the surface of the push plate 22 are both inclined.

[0026] The end of the force-bearing plate 23 is fixedly connected to the outer plate 24, and the force-bearing plate 23 is evenly spaced on the surface of the outer plate 24, and the surface of the outer plate 24 is fixedly connected to an auxiliary spring 25 which plays an elastic reset role, and the other side of the auxiliary spring 25 is fixedly connected to the outer wall of the side plate 18, and an air bag 19 is adhesively connected to the outer wall of the side plate 18, and the other side of the air bag 19 is in contact with the inner wall of the outer plate 24, and the air bag 19 is evenly spaced on the outer wall of the side plate 18.

[0027] A No. 2 pipe 26 is fixedly connected to both the left and right sides of the air storage bag 19, and a second one-way valve 28 is fixedly connected to the surface of the No. 2 pipe 26, and a No. 1 pipe 20 is fixedly connected to the surface of the air storage bag 19 at equal intervals, a nozzle 21 is fixedly connected to the end of the No. 1 pipe 20, and a first one-way valve 27 is fixedly connected to the surface of the No. 1 pipe 20.

[0028] During the movement of the movable plate 5, the movable plate 5 will drive the push plate 22 to move synchronously, and then the push plate 22 will intermittently contact the force-bearing plate 23. When the push plate 22 pushes the force-bearing plate 23, the force-bearing plate 23 is pushed by the push plate 22. At this time, the outer plate 24 moves away from the side plate 18, and then the auxiliary spring 25 is stretched. When the push plate 22 does not push the force-bearing plate 23, the outer plate 24 and the force-bearing plate 23 move back under the action of the auxiliary spring 25. Repeat the above process. The force-bearing plate 23 and the outer plate 24 make reciprocating linear motion in the horizontal direction under the thrust of the push plate 22 and the elastic force of the auxiliary spring 25, and then the outer plate 2 4 will intermittently squeeze the air bag 19. When the air bag 19 is squeezed, the air bag 19 supplies air to the nozzle 21 through the No. 1 pipe 20. When the air bag 19 is not squeezed, the air bag 19 expands back. At this time, the air bag 19 takes in air through the No. 2 pipe 26. The above process is repeated. The nozzle 21 is in intermittent blowing. The nozzle 21 can clean the dust on the surface of the photovoltaic panel and play a self-cleaning role, which is convenient for the subsequent operation of the staff. When the air bag 19 is working, the first one-way valve 27 and the second one-way valve 28 make the flow direction of the air flow from the air to the nozzle 21, ensuring the stability of the operation of the air bag 19 and the nozzle 21.
