Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic power generation, and in particular relates to a distributed photovoltaic power generation snow clearing device. Background Art

[0002] Distributed photovoltaic power generation has been widely used and developed as a clean and renewable way to obtain energy. Distributed photovoltaic power generation systems are usually installed on roofs, open areas and other places. They have the advantages of high flexibility and relatively low construction costs. However, under certain specific climatic conditions, especially in areas with heavy snowfall in winter, it is necessary to clear the snow covering the photovoltaic panels in a timely manner.

[0003] In the related art, snow covering photovoltaic modules is usually cleaned manually using cleaning tools directly on the photovoltaic panels. The cleaning efficiency is low and the work intensity is high. In addition, ice layers are easily formed on the contact surface between the snow and the photovoltaic panels. Simple sweeping and brushing with a brush cannot easily remove the snow. In addition, there is a risk of damaging the surface of the photovoltaic panels during the cleaning process, which cannot provide a 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 clearing device, which effectively solves the above problems.

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes a distributed photovoltaic power generation snow clearing device, including a photovoltaic bracket, a photovoltaic mounting panel, a covering and cleaning component and an ice shaking mechanism. The photovoltaic mounting panel is fixedly arranged on the photovoltaic bracket, and a photovoltaic panel group is detachably arranged on the photovoltaic mounting panel. Moving components are arranged on both sides of the photovoltaic mounting panel. The covering and cleaning component is movably arranged on the surface of the photovoltaic panel group. The covering and cleaning component includes a support cover and a snow shovel. Both ends of the support cover are connected to the moving component. A winding roller is arranged in the support cover, and a waterproof cloth is wound on the winding roller. One end of the waterproof cloth is fixedly arranged on one end of the photovoltaic mounting panel. The snow shovel can be rotatably arranged above one end of the support cover. The bottom of the snow shovel is elastically in contact with the surface of the waterproof cloth. The ice shaking mechanism can be raised and lowered at one end of the support cover. The ice shaking mechanism is arranged below the waterproof cloth. The ice shaking mechanism is used to cooperate with the covering and cleaning component to shake, crush and peel off the covered snow and ice layer in cooperation with the snow shovel when the waterproof cloth is recovered to clear the snow.

[0006] Furthermore, the ice layer shaking mechanism includes a lifting roller, a support member and a shaking device. The lifting roller is arranged below the waterproof cloth, and 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 shaking device. A cross plate is welded between the symmetrically arranged support members. A plurality of mounting openings are provided in parallel on the upper surface of the shaking device. A shaking contact that can be raised and lowered is provided in each mounting opening. A roller is connected to the bottom of the shaking contact. A driving shaft is rotatably provided in the shaking device. The two ends of the driving shaft are keyed to docking gears. A plurality of first cams and second cams are alternately provided on the driving shaft. Each first cam and second cam is correspondingly arranged below each shaking contact, and the first cam and the second cam are both rollingly connected to the corresponding roller.

[0007] Furthermore, there is an angle of 180 degrees between the first cam and the second cam, and limiting grooves are provided on both sides of the shaking contact. The corresponding limiting grooves are provided in the installation opening to match the limiting grooves. A raised edge is also provided on the shaking contact, and the raised edge is located on the inner side of the shaking device. A reset spring is provided between the raised edge and the inner wall of the shaking device, and the reset spring is sleeved on the shaking contact.

[0008] Furthermore, an extended support plate is provided at the bottom of one end of the support cover, and an electric telescopic cylinder and a limit slide are provided on the extended support plate. The electric telescopic cylinder is fixed to the extended support plate with bolts, and the electric telescopic cylinder is fixedly connected to the lower surface of the horizontal plate through the telescopic rod. A limit support plate is provided above the horizontal plate, and the limit slide is symmetrically arranged on both sides of the electric telescopic cylinder, one end of the limit slide is fixedly connected to the surface of the extended support plate, and the other end of the limit slide passes through the horizontal plate and is fixedly connected to the limit support plate.

[0009] Furthermore, when the electric telescopic cylinder lifts the horizontal plate, the docking gears at both ends of the shaking device engage with the drive racks, and the drive racks are symmetrically arranged on both sides of the photovoltaic mounting panel.

[0010] Furthermore, an arc-shaped slide bar is symmetrically provided on the top of the support cover, which movably passes through the snow shovel plate. A support spring is sleeved on the arc-shaped slide bar. A cleaning brush plate is movably provided on the inner side of the support cover. A support slide bar is fixedly provided on the top of the cleaning brush plate. The support slide bar is movably passed through the top of the support cover. A downward pressure spring is also provided between the cleaning brush plate and the top of the support cover. The downward pressure spring is sleeved on the support slide bar. The cleaning brush plate is slidably connected to the upper surface of the waterproof cloth. An unfolding drive motor is fixed to the surface of one side of the support cover with bolts, and the output end of the unfolding drive motor is connected to the winding roller.

[0011] Furthermore, a downwardly recessed mounting portion is provided in the middle of the photovoltaic mounting panel, and the photovoltaic panel group can be 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 panel, and 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, and the other end of the lead screw is rotatably connected to the second mounting portion. The lead screw is threadedly connected to the moving portion, and the moving portion is symmetrically arranged on both sides of the support cover. The second mounting portion is fixedly connected to the other end of the photovoltaic mounting panel, one end of the drive rack is fixedly connected to the first mounting portion, and the other end of the drive 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 part and the second mounting part to cooperate in the lifting and lowering of the ice shaking mechanism.

[0013] The beneficial effects achieved by the present invention using the above structure are as follows:

[0014] By using a waterproof cloth to unfold above the photovoltaic panel group, the photovoltaic panel group is isolated from the snow to avoid direct contact between the snow and the photovoltaic panel group, which may lead to the formation of ice on its surface. This can effectively reduce the difficulty of peeling off the snow and ice in the later stage. In the process of the winding roller winding the waterproof cloth, the ice layer shaking mechanism lifts the shaking device to lift the waterproof cloth and shakes it quickly, which can effectively break up and loosen the snow and ice. When the lifting roller lifts the waterproof cloth, the snow and ice can be smoothly shoveled away in conjunction with the snow shovel, thereby achieving rapid cleaning of snow above the photovoltaic panel group, with high cleaning efficiency and greatly reduced risk of damage to the photovoltaic panel group.

[0015] The alternatingly distributed first cam and second cam installed on the driving shaft can control multiple shaking contacts on the shaking device to achieve rapid alternating extension and retraction through a 180-degree angle setting, thereby achieving high-frequency shaking of the waterproof cloth to increase the loosening effect of the snow and ice layer.

[0016] The lifting and lowering of the shaking device is controlled by an electric telescopic cylinder arranged on the support cover. When snow clearing is required, the shaking device is raised, and the docking of the gears at both ends with the driving rack can be used as a trigger for its startup, so that the shaking device can be automatically opened when the support cover moves downward and rolls up the waterproof cloth. The structure is simple and the switching is flexible. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In one embodiment of the present invention, when the electric telescopic cylinder 28 lifts the horizontal plate 41, the docking gears 20 at both ends of the shaking device 19 engage with the drive rack 10, and the drive rack 10 is symmetrically arranged on both sides of the photovoltaic mounting panel 2.

[0036] In one embodiment of the present invention, an arc-shaped slide bar 22 is symmetrically provided on the top of the support cover 12, and the arc-shaped slide bar 22 movably passes through the snow shovel plate 14. A support spring 23 is sleeved on the arc-shaped slide bar 22.

The downward pressure spring 25 is sleeved on the support slide bar 26, and the cleaning brush plate 24 is slidably connected to the upper surface of the waterproof cloth 17. An unfolding drive motor 16 is fixed to the surface of one side of the support cover 12 with bolts, and the output end of the unfolding drive motor 16 is connected to the winding roller 13.

[0037] In one embodiment of the present invention, a downwardly recessed mounting portion 4 is provided in the middle of the photovoltaic mounting panel 2, and the photovoltaic panel group 33 is detachably arranged in the mounting portion 4. The moving assembly 6 includes a moving motor 7, a lead screw 9, a first mounting portion 8 and a second mounting portion 11. The first mounting portion 8 is fixedly arranged at one end of the photovoltaic mounting panel 2, and the moving motor 7 is bolted to the first mounting portion 8. The output end of the moving motor 7 is connected to one end of the lead screw 9, and the other end of the lead screw 9 is rotatably connected to the second mounting portion 11. The lead screw 9 is threadedly connected to a moving portion 15, and the moving portion 15 is symmetrically arranged on both sides of the support cover 12. The second mounting portion 11 is fixedly connected to the other end of the photovoltaic mounting panel 2, and one end of the drive rack 10 is fixedly connected to the first mounting portion 8, and the other end of the drive rack 10 is fixedly connected to the second mounting portion 11.

[0038] In one embodiment of the present invention, a capacitive sensor for detecting snow accumulation is provided on the upper surface of the support cover 12, and is monitored and regulated by a built-in controller. Displacement sensors are installed on the support cover 12, the first mounting part 8 and the second mounting part 11 to cooperate in the lifting and lowering of the ice shaking mechanism 5.

[0039] Working principle: When using a distributed photovoltaic power generation snow clearing device of the present invention, a capacitive sensor arranged on the upper surface of the support cover 12 serves as a snow monitoring end. When it detects a data change, that is, it believes that snowing has begun, the controller will make the covering and cleaning component 3 unfold, so that the support cover 12 moves to the top of the photovoltaic mounting panel 2 under the control of the moving component 6, and controls the winding roller 13 to unfold the waterproof cloth 17 and cover the photovoltaic panel group 33 through the unfolding drive motor 16. Then the controller adjusts 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 for snow cleaning, the controller will activate the entire device to clear the snow. At this time, under the control of the built-in pre-programmed program of the controller or manual operation, it will control the covering and cleaning component 3 and the ice shaking mechanism 5 to clear the snow.

[0040] As an embodiment, when monitoring snow accumulation using a capacitive sensor disposed on the support cover 12, the following control logic may be employed: each time a cleaning step is completed, the controller automatically resets the sensor reference value (e.g., to zero or calibrated to current environmental parameters). Thus, in subsequent continuous monitoring processes, only when the capacitive sensor value continuously accumulates from the reset reference value to a preset threshold value is it determined to be a valid trigger condition, and a new round of cleaning steps is performed.

[0041] For example: the baseline value of the capacitive sensor after cleaning is reset to 5, and the incremental preset threshold for the new round of triggering conditions is set to 100. When the monitoring value of the capacitive sensor is 90, 90<5+100, then a new round of cleaning cannot be triggered. When the monitoring value is 110, 110>100+5, then 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 amount, and realizes incremental detection. A new round of snow cleaning is triggered only when the snow increment value reaches the triggering preset threshold, rather than a fixed value.

[0042] It's important to note that capacitive sensors offer the core advantages of reliable principles, low cost, and strong environmental adaptability for snow detection. A combination of multi-frequency scanning, temperature compensation, and a hydrophobic coating effectively addresses humidity and temperature interference, meeting the engineering needs of scenarios such as meteorology, photovoltaic power plants, and traffic warnings. Alternatively, interdigital capacitive sensors can be used to replace capacitive sensors, enabling snow detection in extremely cold weather.

[0043] As an alternative cleaning control solution, relevant personnel can abandon capacitive sensor detection as the snow cleaning trigger and use a purely manual operation controller to drive the overall operation of the device.

[0044] When clearing snow, under the pre-programmed control of the controller, the moving component 6 will be controlled to make the moving motor 7 cooperate with the lead screw 9 to drive the support cover 12 to move to the bottom of the photovoltaic installation panel 2, and at the same time, the driving motor 16 will be unfolded to cooperate with the winding roller 13 to start winding the waterproof cloth 17. At this time, one end of the waterproof cloth 17 is fixed to the photovoltaic installation panel 2, and the winding roller 13 gradually moves downward to rewind it. At this time, the displacement sensor set on the support cover 12 and the first mounting part 8 detects that the support cover 12 is at the highest point of the photovoltaic installation panel 2. When the waterproof cloth 17 is rolled up, the controller can control the electric telescopic cylinder 28 to lift the ice layer 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 it to a certain height from the bottom of the waterproof cloth 17. The docking gears 20 connected at both ends are lifted accordingly and docked and meshed with the drive racks 10 on both sides of the photovoltaic installation panel 2. The lifting roller 18 on one side of the shaking device 19 lifts the waterproof cloth 17 from one side. The waterproof cloth 17 is brought into contact with the bottom of the snow shovel 14, and then as the support cover 12 moves, the docking gear 20 is meshed and rolled along the drive rack 10, thereby driving the first cam 35 and the second cam 36 installed thereon to contact with the roller 40, thereby realizing the alternating extension of the shaking contact 32, and realizing its automatic retraction under the cooperation of the return spring 37 and the raised edge 39, thereby performing high-frequency shaking on the snow and ice covering the waterproof cloth 17, breaking them and peeling them off from the waterproof cloth 17, and Under this premise, when the waterproof cloth 17 is rolled up and passes through the lifting roller 18 and the snow shovel 14, the snow shovel 14 quickly scrapes off the broken ice and snow under the cooperation of the arc-shaped slide bar 22 and the support spring 23. In the process of the waterproof cloth 17 that has passed the snow-scraped part and is rolled up onto the reeling roller 13 in the support cover 12, it also passes through the cleaning brush plate 24. At this time, the downward pressure spring 25 cooperates with the support slide bar 26 to enable the cleaning brush plate 24 to further clean the residue on the waterproof cloth 17 to ensure that the waterproof cloth 17 is clean.

[0045] By rolling up the waterproof cloth 17 and scraping off the snow, the support cover 12 stops moving and the waterproof cloth 17 is rolled up when it reaches the second mounting portion 11 and is detected by the displacement sensor installed thereon. At this time, a process of snow cleaning is completed. At this time, the waterproof cloth 17 is rolled up to the winding roller 13 to the maximum extent, and the support cover 12 reaches the bottom of the photovoltaic mounting panel 2. The snow accumulated on the waterproof cloth 17 is successfully cleared, and the photovoltaic panel group 33 is not contacted or covered by the snow, which greatly reduces the risk of it being damaged by snow and during the snow cleaning process.

[0046] It should be noted that the above is only one cycle of snow clearing process, and multiple cycles of snow clearing can be performed according to needs.

[0047] It should be further explained that the control method of the present invention can be automatically controlled by a controller, and the control circuit of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in the field, and this application is mainly used to protect mechanical devices, so this application will not further explain the control method and circuit connection in detail.

[0048] In summary, a distributed photovoltaic power generation snow clearing device of the present invention isolates the photovoltaic panel group from the snow by unfolding a waterproof cloth above the photovoltaic panel group, so as to avoid direct contact between the snow and the photovoltaic panel group and the formation of an ice layer on its surface, which can effectively reduce the difficulty of peeling off the snow and ice layer in the later stage. In the process of the winding roller winding the waterproof cloth, the ice layer shaking mechanism lifts the shaking device to lift the waterproof cloth and shakes it quickly, which can effectively break up and loosen the snow and ice layer. When the lifting roller lifts the waterproof cloth, the snow and ice layer can be smoothly shoveled away in conjunction with the snow shovel, so as to achieve rapid cleaning of the snow above the photovoltaic panel group, with high cleaning efficiency and greatly reduced risk of damage to the photovoltaic panel group. The alternating first cam and second cam installed on the driving shaft can control the multiple shaking contacts on the shaking device to achieve rapid alternating extension and retraction through a 180-degree angle setting, thereby achieving high-frequency shaking of the waterproof cloth to increase the loosening effect of the snow and ice layer. The lifting and lowering of the shaking device is controlled by an electric telescopic cylinder arranged on the support cover. When snow clearing is required, the shaking device is raised, and the docking of the gears at both ends with the driving rack can be used as a trigger for its startup, so that the shaking device can be automatically opened when the support cover moves downward and rolls up the waterproof cloth. The structure is simple and the switching is flexible.
