Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel snow removal technology, and in particular to a photovoltaic snow removal machine. Background Technology

[0002] Snow accumulation covers the surface of photovoltaic panels, blocking sunlight and preventing the modules from receiving solar radiation properly, thus significantly reducing power generation efficiency. It is estimated that after heavy snowfall, the power generation capacity of photovoltaic systems may decrease by 20% to 50%. Timely snow removal can ensure that the photovoltaic panel surfaces are clean, maximizing sunlight reception, improving power generation efficiency, and ensuring the economic benefits of photovoltaic power plants.

[0003] Therefore, an existing photovoltaic snow removal machine, with publication number CN222215675U, first moves a trolley next to the photovoltaic panel when it is necessary to clear snow from the photovoltaic panel. Then, by turning the screw with the handle, the screw moves the cleaning plate, making the cleaning plate fit against the photovoltaic panel. After that, the trolley is moved along the direction in which the photovoltaic panel is placed, and the fan is turned on at the same time. The cleaning plate and the curved plate first clear the large amount of snow from the photovoltaic panel. Then, the fan clears the small amount of snow hidden in the corners through the hose, air duct and air outlet. The cleaning device achieves the effect of cleaning the photovoltaic panel and avoids the situation where the fan cannot clean the photovoltaic panel when there is a lot of snow.

[0004] However, when using cleaning boards and curved boards to remove snow from the surface of photovoltaic panels, they need to slide close to the surface of the photovoltaic panels. The surface of the photovoltaic modules is tempered glass, which has a certain strength. However, using hard or sharp tools such as cleaning boards and curved boards to scrape snow from the bottom can easily scratch or break the glass, causing damage to the modules.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] As shown in Figure 1- Figure 4As shown, a photovoltaic snow removal machine includes a photovoltaic panel 1 and a support frame 2 for fixing the photovoltaic panel 1. The snow removal machine includes two parallel tracks 3 fixedly installed on the support frame 2. The length direction of the tracks 3 is along the laying direction of a row of photovoltaic panels 1, which can ensure that after the row of photovoltaic panels 1 and the support frame 2 are installed and fixed, several tracks 3 are combined into two long complete tracks 3. A sliding seat 4 is slidably installed in the track 3. One side of the sliding seat 4 extends outside the track 3 and is equipped with an electric telescopic rod 5. The two electric telescopic rods 5 are set perpendicular to the upper surface of the photovoltaic panel 1, and the telescopic ends of the two electric telescopic rods 5 are equipped with connecting strips 18 that span the width direction of the photovoltaic panel 1. By moving the sliding seat 4 in the assembled track 3, the connecting strips 18 can be moved back and forth between a row of photovoltaic panels 1. During the back and forth movement, the height of the connecting strips 18 can be adjusted by extending and retracting the electric telescopic rods 5, which is convenient for adjustment according to the thickness of the snow accumulation. By gradually lowering the height of the connecting strips 18, the photovoltaic panels 1 can be cleared. The surface snow is cleared layer by layer; the connecting strip 18 is hollow inside and several first electric push rods 14 arranged along the width direction of the photovoltaic panel 1 are fixedly installed on the top surface of the connecting strip 18. The bottom of the connecting strip 18 is open and a scraper 8 connected to the telescopic end of several first electric push rods 14 is inserted into the opening. During the reciprocating movement of the connecting strip 18, the scraper 8 at its bottom, together with the side of the connecting strip 18, can scrape off the snow. The retraction of the first electric push rods 14 can raise the scraper 8, which is convenient for subsequent cleaning of the thin layer of snow or floating ice on the surface of the photovoltaic panel 1. Rubber sheets 10 are rotatably connected to both sides of the connecting strip 18. The rotation points on the same side of the two rubber sheets 10 pass through the connecting strip 18 and extend outward to be fixedly installed with gears 11. Double-sided racks 12 that mesh with the two gears 11 are inserted into the side of the connecting strip 18, and a second electric push rod 13 for driving the double-sided racks 12 to rise and fall is fixedly installed on the connecting strip 18. When the scraper 8 When the material rises a certain distance, the second electric push rod 13 retracts to raise the double-sided rack 12, which allows the two rubber sheets 10 to rotate downwards by 180 degrees to a vertical position. The bottom edge of the rubber sheets 10 is lower than the bottom edge of the scraper 8. The softness of the two rubber sheets 10 helps to adhere to the snow on the surface of the photovoltaic panel 1, preventing scratches on the surface of the photovoltaic panel 1.

[0024] Firstly, to facilitate device movement: two rows of bottom rollers 16 are rotatably connected to the slide 4, with at least two rollers in each row, and the two rows of bottom rollers 16 are respectively rotatably connected to the two sides of the bottom of the track 3. The upper surface of the slide 4, located inside the track 3, is fitted with a drive roller 9. The outer shell of the drive roller 9 is rotatably connected to a screw 17 that is threaded through the slide 4, and the roller part of the drive roller 9 is rotatably connected to the top surface of the track 3. In use, the drive roller 9 rotates by installing a servo motor, and by designing the top surface of the track 3 to be non-smooth, the drive roller 9 can be raised to tightly press against the non-smooth part of the top surface of the track 3 by rotating the screw 17. Therefore, by utilizing the rolling of the bottom rollers 16 and the bottom surface of the track 3, the slide 4 can slide within the track 3 by the rolling of the drive roller 9, thereby realizing the reciprocating movement of the connecting strip 18 and the scraper 8 between a row of photovoltaic panels 1.

[0025] Secondly, to facilitate adjustment based on snow thickness: the cylinder of the electric telescopic rod 5 is threadedly connected to an internally threaded ring 19 that is rotatably mounted through the slide block 4, and the top edge of the telescopic end of the electric telescopic rod 5 is detachably connected to the surface of the connecting strip 18 via a pin. By rotating the internally threaded ring 19, the height of the cylinder of the electric telescopic rod 5 can be adjusted, thereby facilitating the control of the highest and lowest points of the connecting strip 18 and the scraper 8 during the lifting and lowering process. Furthermore, by rotating the internally threaded ring 19 and removing the pin, the electric telescopic rod 5 can be disassembled and assembled with the internally threaded ring 19 and the connecting strip 18.

[0026] Ultimately, to achieve the seamless removal of the thin layer of snow covering the surface of the photovoltaic panel 1: the inner top surface of the connecting strip 18 is hollow, and an air inlet shell 6 is fixedly installed on the outer top edge of the connecting strip 18 through the hollow and communicating with the inside of the connecting strip 18. A hot air blower 7 is installed at the air inlet of the air inlet shell 6, and an air outlet 15 is opened on the bottom edge of the scraper 8 inserted at the bottom opening of the connecting strip 18. When the surface of the photovoltaic panel 1 is covered with floating ice, two rubber sheets 10 are used to adhere to the ice surface to achieve heat insulation. Then, the hot air blown out by the hot air blower 7 passes through the air inlet shell 6, the connecting strip 18 and the air outlet 15 on the scraper 8 and gathers between the two rubber sheets 10 to melt the floating ice on the surface of the photovoltaic panel 1.

[0027] Working principle: After the electric telescopic rod 5 is installed and fixed with the internal threaded ring 19 and the connecting strip 18, the equipment is assembled on the photovoltaic panel 1 by inserting the slide 4 into the track 3. The drive roller 9 is raised to fit the inner top surface of the track 3 by rotating the screw 17. The rotation of the drive roller 9 causes the slide 4 to move the connecting strip 18 and the scraper 8 back and forth between a row of photovoltaic panels 1. During the back and forth movement of the connecting strip 18, the height of the connecting strip 18 can be lowered by retracting the electric telescopic rod 5. The scraper 8 at its bottom is equipped with... The connecting strip 18 facilitates the scraping of snow layer by layer. When it approaches the surface of the photovoltaic panel 1, the first electric push rod 14 retracts to raise the scraper 8, and the second electric push rod 13 retracts to raise the double-sided rack 12. This allows the two rubber sheets 10 to rotate downwards 180 degrees to a vertical position, with the bottom edge of the rubber sheets 10 lower than the bottom edge of the scraper 8. The softness of the two rubber sheets 10 is used to adhere to the snow on the surface of the photovoltaic panel 1. When moving, the rubber sheets 10 flexibly contact the surface of the photovoltaic panel 1 and clean the snow on the surface of the photovoltaic panel 1.

[0028] The wiring diagrams of the servo motor, hot air blower 7, electric telescopic rod 5, first electric push rod 14 and second electric push rod 13 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the servo motor, hot air blower 7, electric telescopic rod 5, first electric push rod 14 and second electric push rod 13 will not be explained in detail.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
