A vertical plate is fixedly connected to the upper surface of the bottom plate, and a motor is bolted to the outer wall of the vertical plate. It further includes: a self-locking component, which is arranged on the surface of the outer frame. When the self-locking component works, it fixes the required photovoltaic panel, and a placement groove is formed on the surface of the outer frame. When using this array mechanism for the self-locking and anti-disconnection photovoltaic module, when the photovoltaic panel needs to be docked to the outer frame, a photovoltaic panel with a suitable size is directly placed into the placement groove.

After the photovoltaic panel enters the placement groove, the cross bar and the limit block return to their original positions under the action of the connecting spring. At this time, the cross bar presses the photovoltaic panel, playing a role of self-locking, and the installation process is fast and convenient.

Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and specifically to an array mechanism for a self-locking and anti-disconnection photovoltaic module. Background Art

[0002] In the photovoltaic field, photovoltaic modules play a role in energy conversion. They can convert photons into electrons, convert light energy into electrical energy, and then supply power to electrical appliances. Photovoltaic modules have the advantages of energy conservation, environmental protection, safety, and no pollution.

[0003] When a photovoltaic module is working, an array structure is required. During use, the photovoltaic module is docked into the photovoltaic module array structure. The array mechanism can combine multiple photovoltaic modules to improve the overall output power, thereby optimizing the energy conversion and enhancing the reliability of the system.

[0004] However, during the use of photovoltaic modules, in special cases, such as rainy, snowy, sandy, or windy weather, the external environmental factors will affect the continued use of the photovoltaic modules, and in severe cases, it will cause damage to the photovoltaic modules.

[0005] To overcome the above defects, the prior art 1 (a Chinese patent with the application number CN201710276203.7 and the application date of April 25, 2017) is a deployable and retractable solar panel array mechanism, which has a simple structure, is easy to install, has an adjustable light-receiving angle, high space utilization, and is easy to modularize.

[0006] The prior art 2 (a Chinese patent with the application number CN201711074274.5 and the application date of November 5, 2017) is a solar cell module array mechanism that can be deployed and retracted. It has a simple structure and is convenient for processing and manufacturing; it is suitable for outdoor environments and does not require lubrication and maintenance; when in use, it is in a deployed state and will not shade each other, with high space utilization; in case of extreme weather, it can be automatically retracted to protect the solar cell module from damage; when the mechanism is deployed and retracted, it can automatically clean the components, reducing the manual maintenance cost.

[0007] When docking a photovoltaic module, a staff member needs to carry a lot of disassembly and assembly tools to dock the photovoltaic module onto the array structure. However, the devices in the above applications do not have the function of quick docking and self-locking during use, which reduces the work efficiency of the staff. At the same time, during the long-term use of the photovoltaic module, dust, leaves, and other impurities will accumulate on the surface of the photovoltaic module. However, the devices in the above applications do not have the function of self-cleaning when the photovoltaic module is retracted and deployed, increasing the subsequent cleaning workload of the staff.

[0008] In view of the above problems, there is an urgent need to innovate and design on the basis of the original array mechanism for photovoltaic modules. Summary of the Invention

[0009] The purpose of the present invention is to provide an array mechanism for a photovoltaic module with self-locking and anti-disconnection functions, so as to solve the problems proposed in the above background technology that during the use process, it does not have the function of quick docking and self-locking, reducing the work efficiency of the staff, and during the use process, when the photovoltaic module is retracted and deployed, it does not have the self-cleaning function, increasing the workload of subsequent staff cleaning.

[0010] To achieve the above purpose, the present invention provides the following technical solutions: An array mechanism for a photovoltaic module with self-locking and anti-disconnection functions, including a bottom plate and an outer frame.

[0014] Side plates, which are fixedly connected to the upper surface of the bottom plate, and a cleaning component is arranged on the surface of the side plates. The cleaning component removes the dust electrostatically adsorbed on the photovoltaic panel at regular intervals through a circulating air flow.

[0015] Preferably, a limiting rod is fixedly connected to the surface of the vertical plate, and the movable plate is slidably arranged on the surface of the limiting rod. The movable plate is threadedly connected to the long pin. The transition plate has a "work" shape in a top view, a rolling ball is rotatably arranged on the lower surface of the transition block, and the right view of the transition block is an inverted "U" shape.

[0016] Preferably, the self-locking component includes an upper connecting plate fixedly connected to the upper surface of the outer frame. The upper connecting plates are symmetrically distributed about the center of the outer frame, and a cross bar is slidably arranged inside the upper connecting plate.

[0017] Preferably, both ends of the cross bar are located outside the upper connecting plate. The end of the cross bar is inclined, and a limiting block is fixedly connected to the upper surface of the cross bar. The upper surface of the cross bar is concave.

[0018] Preferably, a connecting spring for elastic reset is fixedly connected to the surface of the limiting block, and the other side of the connecting spring is fixedly connected to the inner wall of the upper connecting plate. A stress block is slidably arranged inside the outer frame.

[0019] Preferably, a reset spring for elastic reset is fixedly connected to the lower surface of the stress block, and the other side of the reset spring is fixedly connected to the inner wall of the outer frame. The surface of the stress block is in contact with the inner wall of the outer frame.

[0020] Preferably, the cleaning assembly includes a push plate fixedly connected to the inside of the movable plate. The cleaning assembly further includes a stress plate slidably arranged inside the side plate, and the surfaces of the stress plate and the push plate are both inclined.

[0021] Preferably, an outer plate is fixedly connected to the end of the stress plate, and the stress plates are equally spaced on the surface of the outer plate. An auxiliary spring for elastic reset is fixedly connected to the surface of the outer plate, and the other side of the auxiliary spring is fixedly connected to the outer wall of the side plate.

[0022] Preferably, an air storage bag is adhesively connected to the outer wall of the side plate, and the other side of the air storage bag is in contact with the inner wall of the outer plate. The air storage bags are equally spaced on the outer wall of the side plate.

[0023] Preferably, second pipes are fixedly connected to both the left and right sides of the air storage bag, and a second one-way valve is fixedly connected to the surface of the second pipes. First pipes are fixedly connected to the surface of the air storage bag at equal intervals. The end of the first pipe is fixedly connected to a nozzle, and a first one-way valve is fixedly connected to the surface of the first pipe.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: The array mechanism for the self-locking and anti-detaching photovoltaic module adopts a novel structural design, enabling the photovoltaic panel to be quickly locked onto the array structure with high working efficiency. At the same time, a structure for the quick deployment and contraction of the photovoltaic panel is also provided, improving the flexibility of the use of the photovoltaic panel. Moreover, during the quick deployment and contraction of the photovoltaic panel, the nozzles will work to blow out gas, quickly blowing away the dust on the surface of the photovoltaic panel, facilitating the subsequent cleaning work for the staff. The specific content is as follows:

[0025] (1) When using the array mechanism for the self-locking and anti-detaching photovoltaic module, when the photovoltaic panel needs to be docked onto the outer frame, directly place the photovoltaic panel with a suitable size into the placement groove. At this time, the lower surface of the photovoltaic panel will push the cross bar, causing the cross bar and the limiting block to move in the direction of squeezing the connecting spring. After the photovoltaic panel enters the placement groove, the cross bar and the limiting block return to their original positions under the action of the connecting spring. At this time, the cross bar presses the photovoltaic panel, playing a self-locking role, and the installation process is quick and convenient.

[0026] Further, during the process of the photovoltaic panel entering the interior of the placement groove, the force-bearing block will be pushed by the photovoltaic panel. At this time, the force-bearing block moves in the direction of squeezing the connecting spring, and thus the force-bearing block always has a tendency to move outward from the placement groove. When it is necessary to remove the photovoltaic panel, the cross bar is pulled so that the end of the cross bar does not contact the photovoltaic panel. At this time, the force-bearing block pops out under the action of the connecting spring, and thus the force-bearing block plays a role in assisting disassembly, improving work efficiency;

[0027] (2) For the self-locking and anti-detachment photovoltaic module array mechanism, when it is necessary to deploy the outer frame and the photovoltaic panel, the motor on the surface of the vertical plate is started. When the motor works, the movable plate moves to the right side of the bottom plate under the action of the long pin and the limiting rod. At this time, the outer frame and the photovoltaic panel will be slowly deployed, and thus the outer frame and the photovoltaic panel are put into use. The operation process is fast and convenient, and the work efficiency is high;

[0028] (3) For the self-locking and anti-detachment photovoltaic module array mechanism, during the movement of the movable plate, the movable plate will drive the push plate to move synchronously. Thus, the push plate will intermittently contact the force-bearing plate. At this time, the force-bearing plate makes a reciprocating linear motion in the horizontal direction under the action of the thrust of the push plate and the elastic force of the auxiliary spring. Thus, 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 first pipe. When the air storage bag is not squeezed, the air storage bag expands, and at this time, the air storage bag intakes air through the second pipe. Repeating the above process, the nozzle blows air intermittently, and the nozzle can clean the dust on the surface of the photovoltaic panel, playing a role in self-cleaning and facilitating the subsequent operation of the staff;

[0029] Further, when the air storage bag works, the first one-way valve and the second one-way valve make the flow direction of the air flow be from the air to the nozzle, ensuring the stability of the operation of the air storage bag and the nozzle. The upper surface of the side plate is convex, and the side plate can protect the air storage bag. Description of the Drawings

Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment 1: By arranging the motor 3, the long pin 4 and the movable plate 5, the outer frame 8 can be quickly unfolded, as Figures 1 - 2 and Figure 6 shown:

[0042] 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. Moreover, 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;

[0043] A self-locking and anti-detaching array mechanism for a photovoltaic module further includes:

[0044] Self-locking assembly, the self-locking assembly is arranged on the surface of the outer frame 8. The self-locking assembly uses elastic force and the gravity of the photovoltaic panel itself to position and lock the specified photovoltaic panel on the outer frame 8, and a placement groove 12 is provided on the surface of the outer frame 8; side plate 18, the side plate 18 is fixedly connected to the upper surface of the bottom plate 1, and a cleaning assembly is arranged on the surface of the side plate 18. The cleaning assembly removes the dust electrostatically adsorbed on the photovoltaic panel at regular intervals through the circulating air flow.

[0045] A limiting rod 7 is fixedly connected to the surface of the vertical plate 2, and a movable plate 5 is slidably arranged on the surface of the limiting rod 7. The movable plate 5 is threadedly connected to the long pin 4. The top view of the transition plate 9 is in the shape of a "work" character. A rolling ball 10 is rotatably arranged on the lower surface of the transition block 6, and the right view of the transition block 6 is in the shape of an inverted "U".

[0046] 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 works, the movable plate 5 moves to the right side of the bottom plate 1 under the action of the long pin 4 and the limiting 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 be slowly unfolded, and then the outer frame 8 and the photovoltaic panel are put into use. The operation process is fast and convenient, and the work efficiency is high.

[0047] Embodiment 2: Different from Embodiment 1, by providing the upper connecting plate 13 and the cross bar 14, the photovoltaic panel can be quickly locked during installation, as Figures 3 - 5 shown:

[0048] The self-locking assembly includes an upper connecting plate 13 fixedly connected to the upper surface of the outer frame 8. The upper connecting plates 13 are symmetrically distributed about the center of the outer frame 8. A cross bar 14 is slidably arranged inside the upper connecting plate 13. Both ends of the cross bar 14 are located outside the upper connecting plate 13, and the end of the cross bar 14 is inclined. A limiting block 15 is fixedly connected to the upper surface of the cross bar 14, and the upper surface of the cross bar 14 is concave.

[0049] A connecting spring 16 that plays an elastic reset role is fixedly connected to the surface of the limiting 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 stress block 11 is slidably arranged inside the outer frame 8. A reset spring 17 that plays an elastic reset role is fixedly connected to the lower surface of the stress block 11, and the other side of the reset spring 17 is fixedly connected to the inner wall of the outer frame 8. The surface of the stress block 11 is in contact with the inner wall of the outer frame 8.

[0050] During use, when the photovoltaic panel needs to be docked to the outer frame 8, a photovoltaic panel with appropriate dimensions is directly placed inside the placement groove 12. At this time, the lower surface of the photovoltaic panel will push the cross bar 14, causing the cross bar 14 and the limit block 15 to 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 positions under the action of the connecting spring 16. At this time, the cross bar 14 presses on the photovoltaic panel, playing a self-locking role. The installation process is quick and convenient. During the process of the photovoltaic panel entering the placement groove 12, the force receiving block 11 will be pushed by the photovoltaic panel. At this time, the force receiving block 11 moves in the direction of squeezing the connecting spring 16. Furthermore, the force receiving block 11 always has a tendency to move outward from 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 receiving block 11 pops out under the action of the connecting spring 16. Furthermore, the force receiving block 11 plays an auxiliary disassembly role, improving work efficiency.

[0051] Embodiment 3: Different from Embodiment 2, through the arranged cleaning component, the dust on the surface of the photovoltaic panel can be quickly cleaned, facilitating the subsequent operation of the staff, such as Figures 7 - 9 shown as

[0052] The cleaning component includes a push plate 22 fixedly connected to the inner side of the movable plate 5. The cleaning component also includes a force receiving plate 23 slidably arranged inside the side plate 18, and the surfaces of the force receiving plate 23 and the push plate 22 are both inclined.

[0053] The end of the force receiving plate 23 is fixedly connected with an outer plate 24, and the force receiving plates 23 are equally spaced on the surface of the outer plate 24. And an auxiliary spring 25 for elastic reset is fixedly connected to the surface of the outer plate 24, and the other side of the auxiliary spring 25 is fixedly connected to the outer wall of the side plate 18. An air storage bag 19 is adhesively connected to the outer wall of the side plate 18, and the other side of the air storage bag 19 is in contact with the inner wall of the outer plate 24, and the air storage bags 19 are equally spaced on the outer wall of the side plate 18.

[0054] Both the left and right sides of the air storage bag 19 are fixedly connected with a second pipe 26, and a second one-way valve 28 is fixedly connected to the surface of the second pipe 26. And a first pipe 20 is fixedly connected to the surface of the air storage bag 19 at equal intervals. The end of the first pipe 20 is fixedly connected with a nozzle 21, and a first one-way valve 27 is fixedly connected to the surface of the first pipe 20.

[0055] During the movement of the movable plate 5, the movable plate 5 drives the push plate 22 to move synchronously. As a result, the push plate 22 intermittently contacts 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 thus 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. Repeating the above process, the force-bearing plate 23 and the outer plate 24 perform reciprocating linear motion in the horizontal direction under the action of the thrust of the push plate 22 and the elastic force of the auxiliary spring 25. As a result, the outer plate 24 intermittently squeezes the air storage bag 19. When the air storage bag 19 is squeezed, the air storage bag 19 supplies air to the nozzle 21 through the first pipe 20. When the air storage bag 19 is not squeezed, the air storage bag 19 expands. At this time, the air storage bag 19 intakes air through the second pipe 26. Repeating the above process, the nozzle 21 blows air intermittently. The nozzle 21 can clean the dust on the surface of the photovoltaic panel, playing a role in self-cleaning, which is convenient for the subsequent operation of the staff. When the air storage bag 19 works, 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 storage bag 19 and the nozzle 21.

[0056] The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
