Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module maintenance technology, specifically a contactless de-icing device for TOPCon photovoltaic modules. Background Technology

[0002] With the rapid development of the photovoltaic industry, photovoltaic modules are being used more and more widely in various environments. Especially in cold regions, ice layers easily accumulate on the surface of photovoltaic panels, which seriously affects the power generation efficiency and service life of photovoltaic modules.

[0003] While some de-icing equipment exists on the market, contact de-icing methods can easily damage photovoltaic panels during the de-icing process. They also have limitations in terms of de-icing efficiency, automation, and applicability. Some equipment cannot adapt to photovoltaic panels with different tilt angles, or cannot clean up residual water stains in time after de-icing, causing the water stains to refreeze and affecting the performance of the photovoltaic panels. Therefore, a non-contact de-icing device for TOPCon photovoltaic modules is proposed to address the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the potential damage to photovoltaic panels during the de-icing process caused by conventional contact de-icing methods, limitations in de-icing efficiency, automation, and applicability, and the inability of some devices to adapt to photovoltaic panels with different tilt angles, this invention proposes a non-contact de-icing device for TOPCon photovoltaic modules.

[0005] The technical solution adopted by this utility model to solve its technical problem is a contactless de-icing device for TOPCon photovoltaic modules, including a first support frame, a first movable plate installed on the first support frame, a support disk fixed on the top side of the first movable plate, a drive motor installed inside the support disk, a rotating disk installed on the output shaft of the drive motor, and a de-icing structure, a scraping structure and a storage battery installed on the rotating disk.

[0006] The de-icing structure includes a sliding cylinder, which is fixed to the top side of the rotating disk. A movable column is slidably installed inside the sliding cylinder. Two openings are opened on the sliding cylinder. A first swing rod and a lifting plate are fixed to the outside of the movable column, and the first swing rod and the lifting plate are respectively located in the two openings.

[0007] A heating tube is fixed to the bottom end of the first swing rod. An electric heating wire is installed inside the heating tube. A fan is installed at one end of the heating tube. A semi-circular arc plate is fixed to the bottom side of the outer wall of the heating tube. A first exhaust pipe is fixed to the inner side of the arc plate.

[0008] A grid strip is fixed on one side of the arc-shaped plate, and a second exhaust pipe is provided on the arc-shaped plate. The second exhaust pipe is located between two adjacent grid strips, and one end of the arc-shaped plate is connected to the other end of the heating pipe through a connecting pipe.

[0009] Preferably, the de-icing structure further includes a lifting cylinder, which is fixed to the top side of the rotating disk, and the actuating rod of the lifting cylinder is located on the bottom side of the lifting plate.

[0010] Preferably, electrodes are installed on the bottom side of the movable column and on the bottom inner wall of the sliding cylinder, respectively, and an indicator light is installed on the rotating disk. The two electrodes and the indicator light are connected to a power source.

[0011] Preferably, a limit cap is fixed to the top of the sliding cylinder, and a first spring is fixed between the limit cap and the movable column. A non-contact de-icing method is adopted, in which the arc-shaped plate adheres to the ice surface through the conduction of hot air, rather than directly contacting the surface of the photovoltaic panel. This effectively avoids scratching damage to the photovoltaic panel by mechanical parts. The arc-shaped bottom design of the arc-shaped plate further reduces the risk of scratching the photovoltaic panel during the de-icing movement, ensuring the integrity of the photovoltaic panel.

[0012] Preferably, the scraping structure includes an electrode and a second support frame. The second support frame is fixed to the top side of the rotating disk. A pressing cylinder is installed on the bottom side of the top horizontal plate of the second support frame. A pressing seat is fixed on the rotating disk. A second swing rod is oscillatingly installed inside the pressing seat. A scraper seat is fixed to the bottom end of the second swing rod. A rubber scraper is slidably installed in the transverse slot of the scraper seat. A second spring is fixed between the bottom side of the second swing rod and the outer side of the rotating disk. A pressing plate is fixed to the top end of the second swing rod. The pressing plate is located below the action rod of the pressing cylinder. The scraping structure can automatically clean residual water stains and small-area ice crystals, preventing water stains from freezing again, further ensuring the cleanliness of the photovoltaic panel surface and avoiding the impact of residual water stains on the performance of the photovoltaic panel.

[0013] Preferably, the first movable plate has a screw hole and a sliding hole inside, and the first support frame has two sliding rods and a lead screw installed inside. The lead screw is located between the two sliding rods, and the two ends of the lead screw are rotatably installed at the two ends of the first support frame. A drive motor is installed on the outer side of one end of the first support frame, and the output shaft of the drive motor is connected to one end of the lead screw through a coupling. The sliding rod passes through the sliding hole inside the first movable plate, and the lead screw rotates through the screw hole of the first movable plate by thread.

[0014] Preferably, a frame structure is installed on the bottom side of the first support frame. The frame structure includes a first mounting plate and a second mounting plate. The first mounting plate and the second mounting plate are respectively fixed to the bottom sides of the first support frame. A fixing plate is installed on the inner side of the first mounting plate. A first drive motor is installed on the top side of the fixing plate. A first limit wheel is installed on the output shaft of the first drive motor. The first limit wheel is located on the bottom side of the fixing plate and has a T-shaped structure. The second mounting plate has a threaded hole and a positioning hole. A screw is screwed into the threaded hole. A second movable plate is rotatably installed at one end of the screw. A positioning rod is slidably installed in the positioning hole and fixed to one side of the second movable plate. A second drive motor is installed on the upper side of the second movable plate. A second limit wheel is installed on the output shaft of the second drive motor. When the drive motor operates synchronously, it drives the limit wheel to rotate, thereby moving the first support frame along the photovoltaic panel, realizing the lateral movement of the equipment on the photovoltaic panel for large-area de-icing operations.

[0015] Preferably, a control box is installed on the casing of the storage battery, wherein the control box is used for the electrical control of the drive motor, fan, pressing cylinder, heating wire, lifting cylinder and first drive motor, and the storage battery is provided with a signal communication unit, enabling the storage battery to wirelessly connect with a mobile control terminal.

[0016] The advantages of this utility model are:

[0017] This utility model employs a non-contact de-icing method, utilizing a curved plate in conjunction with hot air to rapidly melt the ice layer. This avoids the potential damage caused by direct contact between mechanical parts and photovoltaic panels in traditional de-icing methods. The curved bottom design of the plate, combined with the automatic adjustment function of the sliding components, further reduces the risk of scratching the photovoltaic panels during de-icing. After de-icing is complete, the curved plate automatically disconnects from the photovoltaic panels, preventing burns caused by contact and ensuring the safety of the photovoltaic panels.

[0018] In terms of energy saving and safety, this solution controls the hot air output of the heating tube and combines it with the indicator light triggered by the electrode to provide timely feedback on the operating status, avoid ineffective operation of the equipment, save energy, and the equipment automatically completes the de-icing operation, reducing the frequency of manual inspections at heights and lowering safety risks. After de-icing is completed, the scraping structure automatically cleans residual water stains and ice crystals to prevent re-icing and further ensure the cleanliness and performance of the photovoltaic panels.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Existing contact-based de-icing methods can easily damage photovoltaic panels during the de-icing process and have limitations in de-icing efficiency, automation, and applicability. Some devices also cannot adapt to photovoltaic panels with different tilt angles. This embodiment provides a contactless de-icing device for TOPCon photovoltaic modules, such as... Figure 1-4As shown, it includes a first support frame 1, a first movable plate 3 is installed on the first support frame 1, a support disk 7 is fixed on the top side of the first movable plate 3, a drive motor is installed inside the support disk 7, a rotating disk 6 is installed on the output shaft of the drive motor, and a de-icing structure 2, a scraping structure 5 and a storage battery 4 are installed on the rotating disk 6.

[0027] The de-icing structure 2 includes a sliding cylinder 213, which is fixed to the top side of the rotating disk 6. A movable column 210 is slidably installed inside the sliding cylinder 213. Two openings are provided on the sliding cylinder 213. A first swing rod 29 and a lifting plate 214 are fixed to the outside of the movable column 210, and the first swing rod 29 and the lifting plate 214 are located in the two openings respectively.

[0028] A heating tube 25 is fixed to the bottom end of the first swing rod 29. The heating tube 25 is equipped with an electric heating wire. A fan 26 is installed at one end of the heating tube 25. A semi-circular arc plate 21 is fixed to the bottom side of the outer wall of the heating tube 25. A first exhaust pipe 24 is fixed to the inner side of the arc plate 21.

[0029] A grid strip 23 is fixed on one side of the arc plate 21. A second exhaust pipe 22 is provided on the arc plate 21. The second exhaust pipe 22 is located between two adjacent grid strips 23. One end of the arc plate 21 is connected to the other end of the heating pipe 25 through a connecting pipe 27.

[0030] The de-icing structure 2 also includes a lifting cylinder 215, which is fixed to the top side of the rotating disk 6, and the actuating rod of the lifting cylinder 215 is located on the bottom side of the lifting plate 214.

[0031] Electrodes 28 are respectively installed on the bottom side of the movable column 210 and the bottom inner wall of the sliding cylinder 213. An indicator light is installed on the rotating disk 6. The two electrodes 28 and the indicator light are connected to the power supply.

[0032] A limit cap 212 is fixed to the top of the sliding cylinder 213. A first spring 211 is fixed between the limit cap 212 and the movable column 210. After the position of the arc plate 21 is adjusted to the ice surface, the lifting cylinder 215 automatically retracts, and the fan 26 operates to introduce air into the heating tube 25. The heating wire inside the heating tube 25 heats the air. The hot air is transported to the first exhaust pipe 24 through the connecting pipe 27 and discharged through the second exhaust pipe 22. The hot air is blown, melting the ice surface.

[0033] Under the expansion reaction force of the first spring 211, the movable column 210 can be pushed downwards, causing the arc plate 21 to contact the ice surface. As the ice melts, the arc plate 21 gradually descends. Since the arc plate 21 is in contact with the first exhaust pipe 24, and the material is thermally conductive, the arc plate 21, carrying heat, adheres to the ice surface, which can increase the melting speed of the ice surface.

[0034] After the ice melt is complete, the movable column 210 descends to its lowest point, and the curved plate 21 also has a gap with the surface of the photovoltaic panel to avoid direct contact between the curved plate 21 and the photovoltaic panel, thereby preventing the curved plate 21 from burning the photovoltaic panel.

[0035] After the ice surface melts, the movable column 210 descends to its lowest point, causing the two electrodes 28 to contact. At this time, the indicator light is energized, indicating that the ice surface in the work area has melted completely, and de-icing operations can be carried out on the lowered area in a timely manner. This reduces energy waste, ensures complete de-icing, achieves non-contact de-icing, reduces damage to the photovoltaic panels, and avoids the danger caused by maintenance personnel checking the ice surface treatment status due to the high installation of the photovoltaic panels.

[0036] The scraping structure 5 includes an electrode 28 and a second support frame 58. The first support frame 58 is fixed to the top side of the rotating disk 6. A pressing cylinder 57 is installed on the bottom side of the top horizontal plate of the second support frame 58. A pressing seat 55 is fixed on the rotating disk 6. A second swing rod 51 is oscillatingly installed inside the pressing seat 55. A scraper seat 53 is fixed to the bottom end of the second swing rod 51. A rubber scraper 52 is slidably installed in the transverse slot of the scraper seat 53. A second spring 54 is fixed between the bottom side of the second swing rod 51 and the outer side of the rotating disk 6. A spring 54 is fixed to the top end of the second swing rod 51. The pressing plate 56 is located below the action rod of the pressing cylinder 57. Under the traction and movement of the first support frame 1, it can drive the scraping structure 5 to move. After the ice melts, there will be a lot of water stains. If not cleaned in time, ice will solidify. When in use, the second swing rod 51 is released freely. Under the contraction of the second spring 54, the second swing rod 51 can be pulled down, so that the rubber scraper 52 contacts the surface of the photovoltaic panel. During the traction process, it can scrape off the residual water stains and clean the ice crystals in a small area to assist the de-icing operation.

[0037] The first movable plate 3 has screw holes and sliding holes inside. The first support frame 1 has two sliding rods 11 and a lead screw 13 installed inside. The lead screw 13 is located between the two sliding rods 11. The two ends of the lead screw 13 are rotatably installed at the two ends of the first support frame 1. A drive motor 14 is installed on the outer side of one end of the first support frame 1. The output shaft of the drive motor 14 is connected to one end of the lead screw 13 through a coupling. The sliding rods 11 pass through the sliding holes inside the first movable plate 3. The lead screw 13 rotates through the screw holes of the first movable plate 3 by thread. During the de-icing operation, the drive motor 14 operates and can drive the lead screw 13 to rotate, realizing the sliding operation of the first movable plate 3 on the sliding rods 11, thereby adjusting the de-icing position.

[0038] A frame structure is mounted on the bottom side of the first support frame 1. The frame structure includes a first mounting plate 84 and a second mounting plate 87. The first mounting plate 84 and the second mounting plate 87 are respectively fixed to the bottom sides of the first support frame 1. A fixing plate 83 is mounted on the inner side of the first mounting plate 84. A first drive motor 81 is mounted on the top side of the fixing plate 83. A first limiting wheel 82 is mounted on the output shaft of the first drive motor 81. The first limiting wheel 82 is located on the bottom side of the fixing plate 83 and has a T-shaped structure. The mounting plate 87 has threaded holes and positioning holes. A screw 88 is screwed into the threaded holes, and a second movable plate 85 is rotatably mounted on one end of the screw 88. A positioning rod 86 is slidably mounted in the positioning holes and fixed to one side of the second movable plate 85. A second drive motor is mounted on the upper side of the second movable plate 85, and a second limit wheel is mounted on the output shaft of the second drive motor. During operation, one side of the first mounting plate 84 is above the inclined surface of the photovoltaic panel, the first limit wheel 82 is located on the upper side of the photovoltaic panel, and the second mounting plate 87 is located on the lower side of the inclined surface of the photovoltaic panel. By rotating the screw 88, the position of the second movable plate 85 can be adjusted with the cooperation of the positioning rod 86, so that the lower first limit wheel 82 is in contact with the bottom side of the photovoltaic panel. When the first drive motor 81 operates synchronously, it can drive the first limit wheel 82 to rotate, thereby realizing the movement of the first support frame 1 along the photovoltaic panel, better realizing the lateral movement of the equipment on the photovoltaic panel, so as to carry out large-area operations.

[0039] A control box is installed on the casing of the storage battery 4. The control box is used for the electrical control of the drive motor 14, the fan 26, the pressing cylinder 57, the heating wire, the lifting cylinder 215 and the first drive motor 81. The storage battery 4 is equipped with a signal communication unit, and the storage battery 4 can be wirelessly connected to the mobile control terminal.

[0040] Working principle: During operation, if there is ice on the photovoltaic panel, it can be placed on the photovoltaic panel using the first support frame 1. The first mounting plate 84 is positioned above the inclined surface of the photovoltaic panel, the first limiting wheel 82 is located on the upper side of the photovoltaic panel, and the second mounting plate 87 is located on the bottom side of the inclined surface of the photovoltaic panel. By rotating the screw 88, the position of the second movable plate 85 can be adjusted with the cooperation of the positioning rod 86, so that the first limiting wheel 82 is in contact with the bottom side of the photovoltaic panel. When the first drive motor 81 operates synchronously, it can drive the first limiting wheel 82 to rotate, thereby enabling the first support frame 1 to move along the photovoltaic panel, better realizing the lateral movement of the equipment on the photovoltaic panel for large-area operations.

[0041] During the de-icing operation, the drive motor 14 operates, which can drive the lead screw 13 to rotate, so that the first movable plate 3 can slide on the sliding rod 11, thereby adjusting the de-icing position;

[0042] During de-icing, the lifting cylinder 215 is controlled by the control box to operate. The lifting cylinder 215 lifts the lifting plate 214 by its lever. During the movement of the lifting plate 214, the movable column 210 slides upward inside the sliding cylinder 213, which drives the first swing rod 29 to rise, thereby pulling the arc plate 21 to the surface of the ice layer. At this time, the first spring 211 is compressed.

[0043] After the curved plate 21 is positioned on the ice surface, the lifting cylinder 215 automatically retracts, and the blower 26 operates to intake air into the heating tube 25. The heating wire inside the heating tube 25 heats the air. The hot air is transported through the connecting pipe 27 to the first exhaust pipe 24 and discharged through the second exhaust pipe 22. The hot air is blown out, melting the ice surface.

[0044] Under the expansion reaction force of the first spring 211, the movable column 210 can be pushed downwards, causing the arc plate 21 to contact the ice surface. As the ice melts, the arc plate 21 gradually descends. Since the arc plate 21 is in contact with the first exhaust pipe 24, and the material is thermally conductive, the arc plate 21, carrying heat, adheres to the ice surface, which can increase the melting speed of the ice surface.

[0045] After the ice melt is complete, the movable column 210 descends to its lowest point, and the curved plate 21 also has a gap with the surface of the photovoltaic panel to avoid direct contact between the curved plate 21 and the photovoltaic panel, thereby preventing the curved plate 21 from burning the photovoltaic panel.

[0046] After the ice surface melts, the movable column 210 descends to its lowest point, causing the two electrodes 28 to contact. At this time, the indicator light is turned on, indicating that the ice surface in the work area has melted and the lowered area can be de-iced in a timely manner. This can reduce energy waste, ensure complete de-icing, achieve non-contact de-icing, reduce damage to the photovoltaic panels, and avoid the danger caused by maintenance personnel checking the ice surface treatment status due to the high installation of the photovoltaic panels.

[0047] An arc-shaped plate 21 is provided on the outer side of the first exhaust pipe 24, and the bottom side of the arc-shaped plate 21 is rounded. With the cooperation of the grille strip 23, it can ensure that the photovoltaic panel is not scratched during the de-icing movement and sliding process, while ensuring the moving angle of the arc-shaped plate 21, which has better adaptability.

[0048] After de-icing is completed, the scraping structure 5 can be moved along with the traction movement of the first support frame 1. After the ice melts, there will be a lot of water stains. If not cleaned in time, ice will solidify. When in use, the second swing rod 51 is released freely. Under the contraction action of the second spring 54, the second swing rod 51 can be pulled down, so that the rubber scraper 52 contacts the surface of the photovoltaic panel. During the traction process, the residual water stains can be scraped off, and small areas of ice crystals can be cleaned to assist in the de-icing operation.

[0049] After the operation is completed, the pressing cylinder 57 presses down the pressing plate 56, causing the second swing rod 51 to swing up, separating the rubber scraper 52 from the photovoltaic panel. At the same time, the lifting cylinder 215 operates, and the rod of the lifting cylinder 215 acts on the lifting plate 214 to lift the movable column 210, lifting the de-icing structure fixed on the movable column 210. With the cooperation of the drive motor in the support plate 7, the rotating plate 6 is driven to rotate, which can realize the rotation of the working direction of the de-icing structure 2 and the scraping structure 5, making the de-icing operation more convenient.
