Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic power generation, and specifically refers to a distributed photovoltaic power generation snow cleaning device. Background Art

[0002] As a clean and renewable energy acquisition method, distributed photovoltaic power generation has been widely applied and developed. Distributed photovoltaic power generation systems are usually installed in places such as rooftops and open areas, with advantages such as high flexibility and relatively low construction costs. However, under some specific climatic conditions, especially in areas with heavy snowfall in winter, it is necessary to clean the snow covering the photovoltaic modules in a timely manner.

[0003] In related technologies, for the snow covering the photovoltaic modules, it is usually cleaned directly on the photovoltaic panels manually using cleaning tools. The cleaning efficiency is low and the working intensity is high. Moreover, an ice layer is likely to form on the contact surface between the snow and the photovoltaic panels. Simple sweeping and brushing with a brush cannot easily remove it, and there is also a risk of damaging the surface of the photovoltaic panels during the cleaning process, which cannot provide good guarantee for the long-term use of the photovoltaic modules. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a distributed photovoltaic power generation snow cleaning device, which effectively solves the above problems.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a distributed photovoltaic power generation snow cleaning device, which includes a photovoltaic support, a photovoltaic mounting plate, a covering and cleaning assembly, and an ice layer shaking mechanism. The photovoltaic mounting plate is fixedly arranged on the photovoltaic support, and a photovoltaic panel group is detachably arranged on the photovoltaic mounting plate. Moving components are arranged on both sides of the photovoltaic mounting plate. The covering and cleaning assembly is movably arranged on the surface of the photovoltaic panel group. The covering and cleaning assembly includes a support cover and a snow scraping plate. Both ends of the support cover are connected to the moving components. A winding roller is arranged inside the support cover, and a waterproof cloth is wound around the winding roller. One end of the waterproof cloth is fixedly arranged at one end of the photovoltaic mounting plate. The snow scraping plate is rotatably arranged above one end of the support cover, and the bottom of the snow scraping plate is elastically abutted against the surface of the waterproof cloth. The ice layer shaking mechanism is arranged at one end of the support cover in a liftable manner. The ice layer shaking mechanism is arranged below the waterproof cloth and is used to cooperate with the covering and cleaning assembly to shake, break, and peel the covered snow and ice layer when the waterproof cloth is retracted, so as to clean the snow.

[0006] Further, the ice layer jitter mechanism includes a lifting roller, a support member, and a jitter device. The lifting roller is arranged below the waterproof cloth. The support members are symmetrically arranged at both ends of the lifting roller. One end of the support member is rotatably connected to one end of the lifting roller, and the other end of the support member is fixedly connected to one end of the jitter device. A cross plate is welded between the symmetrically arranged support members. A plurality of mounting openings are arranged side by side on the upper surface of the jitter device. A jitter contact can be lifted and lowered in each mounting opening. A roller is connected to the bottom of the jitter contact. A driving rotating shaft is rotatably arranged in the jitter device. Docking gears are key-connected to both ends of the driving rotating shaft. A plurality of first cams and second cams are alternately arranged on the driving rotating shaft. Each first cam and second cam is correspondingly arranged below each jitter contact. The first cam and the second cam are both in rolling connection with the corresponding roller.

[0007] Further, the first cam and the second cam form an included angle of 180 degrees. Limiting chutes are arranged on both sides of the jitter contact. Corresponding protrusions are arranged in the mounting opening to cooperate with the limiting chutes. A protrusion edge is also arranged on the jitter contact. The protrusion edge is located inside the jitter device. A return spring is arranged between the protrusion edge and the inner wall of the jitter device. The return spring is sleeved on the jitter contact.

[0008] Further, an extension support plate is arranged at the bottom of one end of the support cover. An electric telescopic cylinder and a limiting slide rod are arranged on the extension support plate. The electric telescopic cylinder is bolted and fixed to the extension support plate. The electric telescopic cylinder is fixedly connected to the lower surface of the cross plate through a telescopic rod. A limiting support plate is arranged above the cross plate. The limiting slide rods are symmetrically arranged on both sides of the electric telescopic cylinder. One end of the limiting slide rod is fixedly connected to the surface of the extension support plate, and the other end of the limiting slide rod penetrates through the cross plate and is fixedly connected to the limiting support plate.

[0009] Further, when the electric telescopic cylinder lifts the cross plate, the docking gears at both ends of the jitter device are engaged with the driving racks. The driving racks are symmetrically arranged on both sides of the photovoltaic installation plate.

[0010] Further, arc-shaped slide rods are symmetrically arranged at the top of the support cover. The arc-shaped slide rods movably penetrate through the snow scraping plate. A support spring is sleeved on the arc-shaped slide rods. A cleaning brush plate is movably arranged inside the support cover. A support slide rod is fixedly arranged at the top of the cleaning brush plate. The support slide rod movably penetrates through the top of the support cover. A pressing spring is also arranged between the cleaning brush plate and the top of the support cover. The pressing spring is sleeved on the support slide rod. The cleaning brush plate is slidably connected to the upper surface of the waterproof cloth. An unfolding driving motor is bolted and fixed to one side surface of the support cover. The output end of the unfolding driving motor is connected to the winding roller.

[0011] Furthermore, a downwardly concave mounting portion is provided in the middle of the photovoltaic mounting plate. The photovoltaic panel group is detachably arranged in the mounting portion. The moving assembly includes a moving motor, a lead screw, a first mounting portion, and a second mounting portion. The first mounting portion is fixedly arranged at one end of the photovoltaic mounting plate. The moving motor is bolted to the first mounting portion. The output end of the moving motor is connected to one end of the lead screw. The other end of the lead screw is rotatably connected to the second mounting portion. A moving portion is threadedly connected to the lead screw. The moving portions are symmetrically arranged on both sides of the support cover. The second mounting portion is fixedly connected to the other end of the photovoltaic mounting plate. One end of the driving rack is fixedly connected to the first mounting portion, and the other end of the driving rack is fixedly connected to the second mounting portion.

[0012] Furthermore, a capacitive sensor for detecting snow accumulation is provided on the upper surface of the support cover and is monitored and regulated by a built-in controller. Displacement sensors are installed on the support cover, the first mounting portion, and the second mounting portion to cooperate with the lifting and lowering of the ice layer shaking mechanism.

[0013] The beneficial effects achieved by the present invention with the above structure are as follows: By using the method of unfolding the waterproof cloth above the photovoltaic panel group to isolate the photovoltaic panel group from the snow accumulation, it is possible to avoid the direct contact between the snow accumulation and the photovoltaic panel group, which may cause ice layers to form on its surface. This can effectively reduce the difficulty of removing the subsequent snow accumulation and ice layers. During the process of the winding roller winding up the waterproof cloth, the ice layer shaking mechanism can lift the shaking device to lift and quickly shake the waterproof cloth, which can effectively shatter and loosen the snow accumulation and ice layers. Thus, when the lifting roller lifts the waterproof cloth, it can cooperate with the snow removal shovel plate to smoothly remove the snow accumulation and ice layers, achieving the rapid cleaning of the snow accumulation above the photovoltaic panel group. The cleaning efficiency is high, and the risk of damage to the photovoltaic panel group is greatly reduced.

[0014] The alternately distributed first cam and second cam installed on the driving shaft, with an included angle of 180 degrees, can control the rapid alternating telescoping of multiple shaking contacts on the shaking device, thereby realizing the high-frequency shaking of the waterproof cloth to increase the loosening effect of the snow accumulation and ice layers.

[0015] The lifting and lowering of the shaking device is controlled by the electric telescopic cylinder provided on the support cover. When snow cleaning is required, the shaking device is lifted, and the docking of the docking gears at both ends of the shaking device with the driving rack can be used as the triggering method for its startup. During the process of the support cover moving downward and winding up the waterproof cloth, the automatic opening of the shaking device can be realized. The structure is simple and the switching is flexible. BRIEF DESCRIPTION OF THE DRAWINGS

The output end of the unfolding drive motor 16 is connected to the winding roller 13.

[0027] In an embodiment of the present invention, an installation part 4 that is recessed downward is arranged in the middle of the photovoltaic installation plate 2. The photovoltaic panel group 33 is detachably arranged in the installation part 4. The moving assembly 6 includes a moving motor 7, a lead screw 9, a first installation part 8, and a second installation part 11. The first installation part 8 is fixedly arranged at one end of the photovoltaic installation plate 2. The moving motor 7 is bolted and fixed to the first installation part 8. The output end of the moving motor 7 is connected to one end of the lead screw 9. The other end of the lead screw 9 is rotatably connected to the second installation part 11.

The other end of the driving rack 10 is fixedly connected to the second installation part 11.

[0028] In an embodiment of the present invention, a capacitive sensor for detecting snow is arranged on the upper surface of the support cover 12, and monitoring and regulation are carried out through a built-in controller. Displacement sensors are installed on the support cover 12, the first installation part 8, and the second installation part 11 to cooperate with the lifting and lowering of the ice layer shaking mechanism 5.

[0029] Working principle: When using a distributed photovoltaic power generation snow cleaning device of the present invention, the capacitive sensor arranged on the upper surface of the support cover 12 serves as the snow monitoring end. When it monitors a data change and considers that it starts to snow, the covering and cleaning assembly 3 is made to be in an unfolded state through the controller. The support cover 12 is moved to the top of the photovoltaic installation plate 2 under the control of the moving assembly 6, and the winding roller 13 is controlled by the unfolding drive motor 16 to unfold the waterproof cloth 17 and cover it above the photovoltaic panel group 33. Then, the controller regulates and monitors the preset value of the snow accumulation degree. When the snow accumulation degree monitoring value of the capacitive sensor reaches the preset value of snow cleaning, the controller will activate the whole device for snow cleaning. At this time, under the control of the pre-programmed program built into the controller or manual operation, the covering and cleaning assembly 3 and the ice layer shaking mechanism 5 will be controlled for snow cleaning; As an example, when monitoring snow accumulation using a capacitive sensor disposed on the support cover 12, the following control logic can be adopted: When each cleaning step is completed, the controller automatically resets the sensor reference value (such as zeroing or calibrating to the current environmental parameters). In this way, during subsequent continuous monitoring, only when the value of the capacitive sensor continuously accumulates from the reset reference value and reaches a preset threshold is it determined as a valid trigger condition, and a new round of cleaning steps is performed; For example: The reference value of the capacitive sensor after cleaning is reset to 5, and the incremental preset threshold for a new round of trigger conditions is set to 100. When the monitored value of the capacitive sensor is 90, 90 < 5 + 100, so a new round of cleaning cannot be triggered. When the monitored value is 110, 110 > 100 + 5, so a new round of cleaning will be triggered. This logic naturally avoids false triggering caused by residual snow, only responds to the newly added snow volume, realizes incremental detection, and triggers a new round of snow cleaning only when the snow increment value reaches the preset threshold for triggering, rather than a fixed value.

[0030] It should be noted that the capacitive sensor has core advantages of reliable principle, low cost, and strong environmental adaptability in snow accumulation detection. Through the combined design of multi-frequency scanning + temperature compensation + hydrophobic coating, the problems of humidity / temperature interference can be effectively solved, meeting the engineering requirements of scenarios such as meteorology, photovoltaic power stations, and traffic warning. On the other hand, as an alternative solution, an interdigital capacitive sensor can be used to replace the capacitive sensor to handle snow accumulation detection in extremely cold weather.

[0031] As an alternative cleaning control solution, relevant personnel can abandon the capacitive sensor detection as the snow cleaning trigger end and adopt the method of manually operating the controller to drive the overall operation of the device.

[0032] During snow removal, under the pre-programmed control of the controller, the moving component 6 is controlled to make the moving motor 7 cooperate with the lead screw 9 to drive the support cover 12 to move towards the bottom of the photovoltaic mounting plate 2. At the same time, the driving motor 16 is unfolded and the winding roller 13 starts to wind the waterproof cloth 17. At this time, one end of the waterproof cloth 17 is fixed to the photovoltaic mounting plate 2, and it gradually moves downward through the winding roller 13 for winding. At this time, the displacement sensors arranged on the support cover 12 and the first mounting part 8, on the premise that the support cover 12 is detected to be at the highest position of the photovoltaic mounting plate 2, when the waterproof cloth 17 is wound, the electric telescopic cylinder 28 can be controlled by the controller to lift the ice shaking mechanism 5. At this time, the electric telescopic cylinder 28 lifts the cross plate 41 through the telescopic rod. At this time, the shaking device 19 rises with it and lifts the waterproof cloth 17 from below to a certain height. The docking gears 20 connected to both ends of it are lifted accordingly and docked and engaged with the driving racks 10 on both sides of the photovoltaic mounting plate 2. The lifting roller 18 on one side of the shaking device 19 lifts the waterproof cloth 17 from one side, so that the waterproof cloth 17 abuts against the bottom of the snow shovel plate 14. Then, as the support cover 12 moves, the docking gears 20 roll along the driving racks 10 in engagement, so as to drive the first cam 35 and the second cam 36 installed thereon to alternately extend the shaking contact 32 through contact with the roller 40, and realize its automatic retraction under the cooperation of the return spring 37 and the convex edge 39, so as to perform high-frequency shaking on the snow and ice covering the waterproof cloth 17, break it and peel it off from the waterproof cloth 17. Thus, on this premise, when the waterproof cloth 17 is wound and passes through the lifting roller 18 and the snow shovel plate 14, the snow shovel plate 14 quickly scrapes off the broken ice and snow under the cooperation of the arc-shaped slide rod 22 and the support spring 23. During the process that the waterproof cloth 17 after snow scraping is wound onto the winding roller 13 in the support cover 12, it will also pass through the cleaning brush plate 24. At this time, the pressing spring 25 cooperates with the support slide rod 26 to make the cleaning brush plate 24 further clean the residue on the waterproof cloth 17 to ensure the cleanliness of the waterproof cloth 17; Through the winding of the above-mentioned waterproof cloth 17 and the snow scraping and cleaning, until the support cover 12 reaches the second mounting part 11 and is detected by the displacement sensor installed thereon, the movement and the winding of the waterproof cloth 17 are stopped. At this time, the snow removal of one process is completed. At this time, the waterproof cloth 17 is wound onto the winding roller 13 to the greatest extent, and the support cover 12 reaches the bottom of the photovoltaic mounting plate 2. The snow accumulated on the waterproof cloth 17 is successfully removed, and the photovoltaic panel group 33 is not contacted and covered by the snow, greatly reducing the risk of damage caused by the snow and the process of removing the snow.

[0033] It should be noted that the above is only a process of snow removal in one cycle, and multiple cycles of snow removal can be carried out according to needs.

[0034] It should be further noted that the control method of the present invention can be automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art, which belongs to the common general knowledge in the art. And this application is mainly used to protect mechanical devices, so the control method and circuit connection will not be further explained in detail in this application.

[0035] In summary, for a distributed photovoltaic power generation snow cleaning device of the present invention, by using the method of unfolding a waterproof cloth above a photovoltaic panel group, the photovoltaic panel group is isolated from the snow, so as to avoid the direct contact between the snow and the photovoltaic panel group resulting in the formation of ice layers on its surface, which can effectively reduce the difficulty of later snow and ice layer stripping. During the process of the winding roller winding the waterproof cloth, the ice layer shaking mechanism can lift the shaking device to lift and quickly shake the waterproof cloth by raising the shaking device, which can effectively break and loosen the snow and ice layers. Thus, when the lifting roller lifts the waterproof cloth, it can cooperate with the snow shoveling plate to smoothly remove the snow and ice layers, realizing the rapid cleaning of the snow above the photovoltaic panel group, with high cleaning efficiency and greatly reducing the risk of damage to the photovoltaic panel group. The alternately distributed first cam and second cam installed on the driving rotating shaft, with an included angle of 180 degrees, can control multiple shaking contacts to achieve rapid alternating expansion and contraction on the shaking device, thereby realizing high-frequency shaking of the waterproof cloth to increase the loosening effect of the snow and ice layers. The lifting of the shaking device is controlled by the electric telescopic cylinder arranged on the support cover. When snow cleaning is required, the shaking device is lifted, and the docking of the docking gears at both ends of the shaking device with the driving rack can be used as the triggering method for its startup, so that during the process of the support cover moving downward and winding the waterproof cloth, the automatic opening of the shaking device is realized, with a simple structure and flexible switching.
