Description

Technical Field

[0001] This utility model relates to the technical field of snow removal for photovoltaic modules, and in particular to a bidirectional snow remover. Background Technology

[0002] In high-latitude regions, mountainous areas, and areas with heavy winter snowfall, photovoltaic (PV) modules often face the problem of snow accumulation. Snow covering the surface of PV modules severely blocks sunlight, leading to a significant decrease in power generation efficiency. Studies have shown that when the surface of a PV module is completely covered by snow, its power generation may drop to almost zero. Furthermore, prolonged snow accumulation can cause localized excessively low temperatures within the PV modules, leading to performance degradation and mechanical damage to the cells, such as microcracks and delamination, thus shortening the lifespan of the PV modules. Simultaneously, the ice-water mixture formed after snow melts may refreeze in cold weather, further increasing the difficulty of cleaning and potentially causing even greater damage to the PV modules.

[0003] To address the issue of snow accumulation on photovoltaic (PV) modules, various snow-scraping technologies and devices have emerged. For example, patent CN212627807U employs a snow-scraping device placed on the top surface of the PV module. Operators continuously move the device along the scraping direction to scrape the snow off the PV module sequentially, thus clearing the snow. However, in practical use, the device's structure limits its scraping to one direction only. Since PV modules are often arranged in an array, when scraping snow from right to left on a horizontally arranged array, the device ends up on the left side of that module. Because the device can only scrape in one direction, it must be manually moved to the right side of the next PV module before the next round of snow removal can begin. This process is time-consuming and physically demanding, resulting in low efficiency. Utility Model Content

[0004] Based on this, a two-way snowplow is provided to solve the problem of low snow removal efficiency caused by the fact that existing technologies can only perform one-way snow removal.

[0005] Specifically, the technical solutions include the following:

[0006] A two-way snowplow, comprising:

[0007] The snow-scraping component is laid out along a first direction and bent back and forth along a second direction, having multiple pleated structures. The lower side of the pleated structures is used to fit the light-receiving surface of the photovoltaic module and to scrape snow when moving.

[0008] The snow shovel includes at least two snow shovels. Snow shovels are provided on both the left and right sides of the snow wiping component. The lower end of the snow shovel is attached to or connected to the snow wiping component, and the upper end of the snow shovel extends along the second direction. The snow shovel is used to scrape snow when moving.

[0009] The snow scraper and the snow shovels located on both sides of the snow scraper are used to scrape snow in the forward direction and / or in the reverse direction when the snow scraper covers the light-receiving surface in the third direction and moves in the first direction.

[0010] The first direction is the length direction of the light-receiving surface, the third direction is the width direction of the light-receiving surface, and the second direction is perpendicular to both the first and third directions.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] In one implementation, the two-way snowplow includes:

[0013] The snow scraper frame has a triangular structure. Two sides of the triangular structure are the first mounting sides, and the other side is the second mounting side. Each first mounting side is connected to the left and right sides of the snow scraping component and a snow shovel.

[0014] In one implementation, the two-way snowplow also includes:

[0015] A support frame, with its two ends connected to the middle of the two first mounting edges respectively;

[0016] The handrail protrudes in the direction away from the snow-wiping component. One side of the handrail is connected to the second mounting edge, and the other side of the handrail is connected to the support frame.

[0017] In one implementation, the snow scraper is an isosceles triangle, and the orthographic projection of the middle part of the handrail coincides with the center line of the snow scraper.

[0018] The two-way snowplow also includes:

[0019] The guide wheel is connected to the position where the two first mounting edges intersect. The guide wheel is used to extend out of the light-receiving surface in a third direction and roll against the side of the photovoltaic module.

[0020] In one implementation, the two-way snowplow also includes:

[0021] The positioning part is arranged parallel to the second mounting edge. The positioning part is connected to the top surface of the snow scraper and is located near the end where the two first mounting edges intersect. The positioning part extends out of the triangular structure of the snow scraper and forms a triangular positioning hole at the end of the snow scraper.

[0022] The guide rope has two adjustable loop knots, one of which is used to engage with the positioning part, and the other is used to fix the position of the guide rope.

[0023] The guide rod includes a guide pin located at one end of the guide rod. The guide pin is T-shaped and is used to extend into the positioning hole and assist in the movement of the snow scraper.

[0024] In one implementation, the two-way snowplow also includes:

[0025] Blower nozzle,

[0026] The sprinkler pipe has a corresponding air blower pipe and a sprinkler pipe fixed on the first mounting side, and the air blower pipe and the sprinkler pipe extend along the length of the first mounting side.

[0027] Both the air blower and the water sprayer have multiple outlet holes along their length.

[0028] In one implementation, the angle between the axis of the outlet hole and the light-receiving surface is acute, and the air outlet or water outlet direction of the outlet hole is towards the light-receiving surface.

[0029] In one implementation, the two-way snowplow also includes:

[0030] air pump,

[0031] water pump,

[0032] The air delivery hose has two ends connected to the blower nozzle and the air pump, respectively.

[0033] The water delivery hose has two ends connected to a sprinkler pipe and a water pump, respectively.

[0034] In one implementation, both the snow shovel and the snow scraper are mesh structures. The snow shovel scrapes the snow a second time on the snow-facing side through the mesh structure.

[0035] In one implementation, the snow shovel is a flat, plate-like structure, and the angle between the snow shovel and its direction of movement in the first direction is an obtuse angle.

[0036] The beneficial effects of this utility model are as follows:

[0037] Since this solution includes two snow shovels, and the snow shovels are located on both sides of the snow removal component and cover the light-receiving surface in the third direction, when the bidirectional snow remover is moved in the first direction of the light-receiving surface to remove snow, the snow shovels can simultaneously remove snow in both the first and second directions of the light-receiving surface. In addition, the snow shovels are the main snow removal structure of the bidirectional snow remover when it is removing snow, and are used to scrape off most of the snow on the light-receiving surface.

[0038] Because the snow wiping component bends back and forth along the second direction and has multiple pleats, the lower side of the pleats of the snow wiping component is in contact with the light-receiving surface. Thus, by using the snow wiping component to slide and scrape the snow against the light-receiving surface, the remaining snow after the snow shovel has scraped the snow is removed. Since the snow wiping component is directly in contact with the light-receiving surface and scrapes the snow, the adhesive substances on the light-receiving surface can also be removed well.

[0039] Therefore, compared with existing technologies that can only perform unidirectional snow removal, when continuously removing snow from arrayed photovoltaic modules, existing technologies require manual labor to lift the snow removal device from the end of the previous row of photovoltaic modules back to the beginning of the next row before the photovoltaic modules can continue to be cleared. Because the snow removal device is time-consuming to move, the snow removal efficiency is reduced. When this device is clearing snow, it can move forward and backward along the first direction. After clearing the snow from the beginning to the end of the previous row of photovoltaic modules, it can directly clear the snow from the end to the beginning of the next row of photovoltaic modules. This effectively reduces the transportation distance and time of the photovoltaic modules, effectively improves the snow removal efficiency, and reduces the demand on the operator's physical strength.

[0057] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit its scope. It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show components relevant to this utility model and are not drawn according to the actual number, shape, and size of the components. In actual implementation, the form, quantity, and proportion of each component can be arbitrarily changed, and the component layout may be more complex. The structures, proportions, sizes, etc., depicted in the accompanying drawings are only used to complement the content disclosed in the specification for those skilled in the art to understand and read, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the technical content disclosed in this utility model.

[0058] In the embodiments, such as Figure 2 , Figure 4 and Figure 7 The meanings of the arrows are explained as follows: X is the first direction, Y is the second direction, and Z is the third direction; the first direction is the length direction of the light-receiving surface 17-1, the third direction is the width direction of the light-receiving surface 17-1, and the second direction is perpendicular to both the first and third directions.

[0059] A two-way snowplow, see Figure 1 and Figure 2 The bidirectional snowplow includes a snow-scraping component 1 and a snow shovel 2. The snow-scraping component 1 is spread out along a first direction and bends back and forth along a second direction and has multiple pleated structures. The lower side of the pleated structure is used to fit the light-receiving surface 17-1 of the photovoltaic module 17 and to scrape snow when moving. The snow shovel 2 includes at least two snow shovels. Snow shovels 2 are provided on both the left and right sides of the snow-scraping component 1. The lower end of the snow shovel 2 is fitted or connected to the snow-scraping component 1, and the upper end of the snow shovel 2 extends along the second direction. The snow shovel 2 is used to scrape snow when moving.

[0060] The snow-wiping component 1 and the snow shovels 2 located on both sides of the snow-wiping component 1 are used to perform forward and / or reverse snow scraping when covering the light-receiving surface 17-1 along a third direction and moving along the first direction. Since the snow-wiping component 1 and the snow shovels 2 on both sides can cover the light-receiving surface 17-1 along a third direction, that is, the width direction of the light-receiving surface 17-1 is covered, the bidirectional snow remover can cover the entire width direction of the light-receiving surface 17-1 of the photovoltaic module 17 in one go when moving along the first direction and scraping snow, improving the completion rate of one snow scraping. This allows the bidirectional snow remover to achieve full coverage of the third direction of the light-receiving surface 17-1 by continuously scraping snow along the first direction, thereby avoiding secondary re-scraping after snow scraping and improving the effect of one-time snow scraping on snow removal.

[0061] For the adoption of this solution, please refer to [link / reference]. Figure 3 and Figure 6Since this design includes two snow shovels 2, and the snow shovels 2 are located on both sides of the snow removal component 1 and cover the light-receiving surface 17-1 along a third direction, when the bidirectional snowplow moves along the first direction of the light-receiving surface 17-1 to remove snow, the snow shovels 2 can simultaneously remove snow in both the first and second directions of the light-receiving surface 17-1. Furthermore, the snow shovels 2 serve as the main snow removal structure for the bidirectional snowplow during snow removal, scraping off most of the accumulated snow on the light-receiving surface 17-1. Because the snow removal component 1 is bent back and forth along the second direction and has multiple pleats, the lower sides of the pleats of the snow removal component 1 are all in contact with the light-receiving surface 17-1. This allows for sliding snow removal by the snow removal component 1 against the light-receiving surface 17-1, removing the remaining snow after the snow shovels 2 have removed it. Since the snow removal component 1 is directly in contact with the light-receiving surface 17-1 and performs scraping snow removal, the light-receiving surface... Adhesive substances on surface 17-1 can also be effectively removed. Therefore, compared with existing devices that can only perform unidirectional snow removal, when continuously removing snow from the array of photovoltaic modules 17, existing technologies require manual labor to lift the snow removal device from the end of the previous row of photovoltaic modules 17 back to the beginning of the next row of photovoltaic modules 17 before the photovoltaic modules 17 can continue to be removed. Because the snow removal device is time-consuming to move, the snow removal efficiency is reduced. When this device removes snow, it can move forward and backward along the first direction. After completing the snow removal of the previous row of photovoltaic modules 17 from the beginning to the end, it can directly remove the snow from the end to the beginning of the next row of photovoltaic modules 17. This effectively reduces the transportation distance and time of the photovoltaic modules 17, effectively improves the snow removal efficiency, and reduces the demand on the operator's physical strength.

[0062] See Figure 3 and Figure 6 In this solution, the snow scraping component 1 and the snow shovel 2 can be two connected independent parts or a one-piece molded structure. The specific structural form is selected according to the hardness of the raw material and the corresponding snow thickness. When only the snow scraping component 1 and the snow shovel 2 are provided, the movement and snow scraping of the bidirectional snow remover can be driven by pushing the back side of the snow shovel 2 facing the snow, or by pushing the other snow shovel 2 facing away from the snow, or by pushing the snow scraping component 1.

[0063] In this embodiment, the adhering material may be animal droppings such as bird droppings; the snow-facing side is the side of the bidirectional snowplow facing the snow, that is, the corresponding "snow-facing snow shovel 2" is the side of the snow shovel 2 on both sides of the snow scraper frame 3 that is closer to the snow, and the "snow-facing snow shovel 2" is the snow shovel 2 that first comes into contact with the snow when the bidirectional snowplow moves to clear the snow.

[0064] In this embodiment, the shape of the snow shovel 2 is not limited. The snow shovel 2 can be flat, curved, or have a reciprocating fold structure, but the snow shovel 2 needs to extend upwards to ensure that the snow shovel 2 has a blocking and pushing effect on the snow in the vertical direction.

[0065] In some embodiments, see Figure 1 and Figure 3 The two-way snowplow includes a snow scraper frame 3, which has a triangular structure. Two sides of the triangular structure of the snow scraper frame 3 are first mounting sides, and the other side is a second mounting side. Each first mounting side is connected to the left and right sides of the snow scraping component 1 and a snow shovel 2. In this way, by setting the triangular snow scraper frame 3 and connecting the snow scraping component 1 and the snow shovel 2 through the two first mounting sides of the snow scraper frame 3, the frame structure of the two-way snowplow is made more stable, reducing the deformation of the two-way snowplow during snow scraping.

[0066] In the embodiments, see Figure 6 Since both the snow scraper 1 and the snow shovel 2 completely cover the light-receiving surface 17-1 along the third direction, the two ends of the two first mounting sides extend a certain distance from the sides of the width of the light-receiving surface 17-1 along the third direction. This makes the snow scraper 1 and the snow shovel 2 better cover the width of the light-receiving surface 17-1 along the third direction, and also leaves some room for the position change when the bidirectional snowplow moves, ensuring that the bidirectional snowplow can also completely cover the light-receiving surface 17-1 when it moves.

[0067] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The bidirectional snowplow also includes a support frame 4 and a handle 5. The two ends of the support frame 4 are respectively connected to the middle of the two first mounting sides. The handle 5 protrudes in the direction away from the snow scraping component 1. One side of the handle 5 is connected to the second mounting side, and the other side of the handle 5 is connected to the support frame 4. In this way, by setting the support frame 4, the structure of the snow scraper 3 is made more stable. In addition, since the first mounting side is used to connect the snow shovel 2, and the snow shovel 2 is used to perform the first snow scraping on the snow-facing surface, the snow shovel 2 is subjected to greater force, and the structural strength requirements of the first mounting side are higher. The support frame 4 strengthens the middle of the two first mounting sides to prevent deformation of the first mounting sides after long-term use. The handle 5 is set to push and bear force during snow scraping, making it convenient to move the entire bidirectional snowplow along the length of the light-receiving surface 17-1 for snow scraping.

[0068] In some embodiments, see Figure 1 , Figure 3 and Figure 4The snow scraper frame 3 is an isosceles triangle, and the orthographic projection of the middle part of the handle 5 coincides with the center line of the snow scraper frame 3. This allows the operator to ensure that when gripping the handle 5 and pushing the bidirectional snowplow to scrape snow, the orthographic projection of the handle 5 is perpendicular to the light-receiving surface 17-1 of the photovoltaic module 17 along the first direction. When the snow shovel 2 is a long, plate-like structure and is set parallel to the first mounting edge, the angle between the snow shovel 2 near the snow-facing surface and the bidirectional snowplow's movement direction in the first direction is obtuse. Specifically, when scraping snow, the triangular snow scraper frame 3 is placed above the tilted light-receiving surface 17-1 of the photovoltaic module 17, with the second mounting edge extending below the light-receiving surface 17-1. The orthographic projection of the middle part of the handle 5 coincides with the center line of the snow scraper frame 3. Therefore, for the snow shovel 2 located on the snow-facing surface, when scraping snow, it scrapes snow on the same plane as the third upward direction of the light-receiving surface 17-1. Simultaneously, snow located on the same plane along the second direction will first contact the lower part of the snow shovel 2 on the snow-facing side. As the bidirectional snowplow gradually moves to scrape the snow, the snow above the plane will gradually contact the snow shovel 2 on the snow-facing side and be scraped off. This snow scraper frame 3 is not aligned with the third direction, so that snow along the width direction of the light-receiving surface 17-1 and located on the same vertical plane will not contact the snow shovel 2 at the same time. This results in a certain time difference when the snow is scraped off. That is, when scraping the snow, the snow along the width direction of the light-receiving surface 17-1 and located on the same vertical plane will not fall at the same time. The snow above the light-receiving surface 17-1 is less likely to accumulate at the bottom when it falls, which facilitates the removal of snow and also avoids the situation where the operator has to push the snow with difficulty due to snow accumulation.

[0069] In the embodiments, see Figure 1 The bidirectional snowplow employs an axisymmetric arrangement of its structure.

[0070] See Figure 4 and Figure 5 The bidirectional snowplow also includes a guide wheel 10, which is connected to the intersection of the two first mounting edges. The guide wheel 10 extends out of the light-receiving surface 17-1 in a third direction and rolls against the side of the photovoltaic module 17. Thus, by setting the guide wheel 10, for the triangular snow scraper 3, after the snow scraper 3 is placed on the light-receiving surface 17-1, the corresponding handle 5 is positioned lower on the snow scraper 3 for the operator to push it, and the corresponding guide wheel 10 is positioned higher on the snow scraper 3 as a positioning structure for the top of the snowplow to slide against the photovoltaic module 17. This makes the bidirectional snowplow more stable when moving along the first direction on the light-receiving surface 17-1.

[0071] In some embodiments, see Figure 3 and Figure 9The bidirectional snowplow also includes a positioning part 6, a guide rope 8, and a guide rod 9. The positioning part 6 is arranged parallel to the second mounting edge and is connected to the top surface of the snow scraper 3 and located near the end where the two first mounting edges intersect. The positioning part 6 extends out of the triangular structure of the snow scraper 3 and forms a triangular positioning hole 7 at the end of the snow scraper 3. The guide rope 8 is provided with two adjustable annular knots 8-1, one of which is used to engage with the positioning part 6, and the other is used to fix the position of the guide rope 8. The guide rod 9 includes a guide pin 9-1, which is located at one end of the guide rod 9. The guide pin 9-1 is T-shaped and is used to extend into the positioning hole 7 and to assist the movement of the snow scraper 3. In this way, by setting the positioning part 6 in conjunction with the guide rope 8, when it is necessary to push the bidirectional snowplow to scrape snow, one of the slip knots 8-1 of the guide rope 8 can be put onto the positioning part 6 by the push of the guide pin 9-1 of the guide rod 9, and the other slip knot 8-1 can be pulled by the snowplow operator to scrape snow, or fixed to the corresponding mobile machinery to provide auxiliary force to pull the bidirectional snowplow to scrape snow. Since the handrail 5 and the positioning part 6 are located on both sides of the width direction (third direction) of the light-receiving surface 17-1 of the photovoltaic module 17, each bidirectional snowplow can be equipped with two operators when performing snow scraping operations. The two operators are located on both sides of the width direction (third direction) of the light-receiving surface 17-1 of the photovoltaic module 17. One pushes the handrail 5 and the other pulls the slip knot 8-1 of the guide rope 8, so as to facilitate the bidirectional snowplow to be pulled along the first direction to move the photovoltaic module 17 and perform snow removal, effectively improving snow removal efficiency.

[0072] In the embodiments, generally, see Figure 7 The light-receiving surface 17-1 of the photovoltaic module 17 is inclined. Therefore, when the bidirectional snow remover is placed on the light-receiving surface 17-1 for snow removal, the second mounting edge extends out of the lower side of the light-receiving surface 17-1, the handrail 5 is located on the lower side of the light-receiving surface 17-1 in the width direction, that is, the handrail 5 is located on the lower side of the light-receiving surface 17-1 in the third direction, and the positioning part 6 extends out of the upper side of the light-receiving surface 17-1.

[0073] In some embodiments, see Figure 8The bidirectional snowplow also includes a blower nozzle 11 and a water spray nozzle 12. Corresponding blower nozzles 11 and 12 are fixed on the first mounting side, extending along the length of the first mounting side. Both the blower nozzle 11 and 12 have multiple outlet holes along their length. The blower nozzle 11 blows air forward in the direction of travel of the bidirectional snowplow, facilitating the removal of accumulated snow and reducing resistance during snow removal. The water spray nozzle 12 cleans the snowplow in summer. Through the processes of watering, scraping, and subsequent natural drying, the cleaning efficiency of the light-receiving surface 17-1 is higher, making it easier to remove residual dirt. The multiple outlet holes ensure that the air and water are sprayed more evenly along the length of the first mounting side.

[0074] In some embodiments, the axial direction of the outlet hole forms an acute angle with the light-receiving surface 17-1, and the air outlet direction or water outlet direction of the outlet hole is towards the light-receiving surface 17-1. In this way, by tilting the direction of the outlet hole towards the light-receiving surface 17-1 at a certain angle, the air blown out along the outlet hole of the air blower pipe 11 or the water sprayed along the water sprayer pipe 12 will be sprayed towards the light-receiving surface 17-1, thereby facilitating the blowing off of snow on the light-receiving surface 17-1 and facilitating the washing off of impurities on the light-receiving surface 17-1, which is beneficial for cleaning.

[0075] In the embodiment, the angle at which the outlet hole is tilted toward the light-receiving surface 17-1 can be set to 30 degrees or 45 degrees. Since the bidirectional snowplow is a cleaning structure that can be moved on both sides, when the bidirectional snowplow moves in one direction, the blower nozzle 11 and water spray nozzle 12 on the snow scraper frame 3 that is closer to the direction of movement of the bidirectional snowplow are in working condition. The state of the blower nozzle 11 and water spray nozzle 12 on the other side of the snow scraper frame 3 is not restricted, and the other side can be opened or closed according to the specific situation.

[0076] In the embodiments, see Figure 8 The blower nozzle 11 and the water spray nozzle 12 are in Figure 1 The snow scraper 3 has an axisymmetric structure on both sides. An example of its use as a cleaning tool in non-winter conditions is as follows: working from west to east, the air blower 11 near the east side blows away loose dust, leaves, and other attached debris. Any debris that cannot be blown away is moistened by the water sprayer 12 near the east side, which sprays water onto the sun-receiving surface 17-1 of the photovoltaic module 17. Then, the snow scraper 1 wipes the sun-receiving surface 17-1, removing accumulated dust or bird droppings. The water sprayer 12 near the west side then rinses it again with high-pressure water. Finally, the air blower 11 near the west side dries the sun-receiving surface 17-1 of the photovoltaic module 17, preventing dust and mud from settling on the damp surface. Because the entire bidirectional snow remover has an axisymmetric structure, the functions of the air blower 11 and water sprayer 12 on both sides are interchangeable when the tool is used from east to west; this will not be elaborated further here.

[0077] In some embodiments, see Figure 8 The two-way snowplow also includes an air pump 13, a water pump 14, an air supply hose 15, and a water supply hose 16. The two ends of the air supply hose 15 are connected to the air-blowing nozzle 11 and the air pump 13, respectively; the two ends of the water supply hose 16 are connected to the water-spraying nozzle 12 and the water pump 14, respectively. Thus, the air pump 13 supplies air to the air-blowing nozzle 11 through the air supply hose 15, enabling the air-blowing nozzle 11 to continuously blow air; the water pump 14 supplies water to the water-spraying nozzle 12 through the water supply hose 16, enabling the water-spraying nozzle 12 to continuously spray water and clean the sun-receiving surface 17-1.

[0078] In this embodiment, the ends of the blower nozzle 11 and the water spray nozzle 12 facing away from the air pump 13 and the water pump 14 are sealed, so that the corresponding water and air can only flow out from the outlet hole, ensuring the rinsing effect on the sun-receiving surface 17-1. The air pump 13 and the water pump 14 are placed on a transport vehicle, and the movement of the transport vehicle drives the air pump 13 and the water pump 14 to move along with the snow scraper.

[0079] In some embodiments, see Figure 1 and Figure 3 Both the snow shovel 2 and the snow scraping component 1 have a mesh structure. The snow shovel 2 scrapes the snow a first time on the snow-facing surface through the mesh structure, and the snow scraping component 1 scrapes the snow a second time. In this way, the mesh structure of the snow shovel 2 has a cutting effect on the snow, and some of the snow will pass through the mesh of the snow shovel 2 and fall into the area of ​​the snow scraping component 1. This reduces the resistance when the snow shovel 2 moves and scrapes the snow, thereby reducing the physical effort required by the operator to push it and improving the efficiency of snow removal. The snow that falls into the area of ​​the snow scraping component 1 will be dragged and scraped off by the mesh snow scraping component 1. At the same time, the snow scraping component 1 has multiple direct contact points with the light-receiving surface 17-1. When the snow scraping component 1 moves, it will also scrape the surface of the light-receiving surface 17-1 and remove the adhering substances on the surface of the light-receiving surface 17-1. This makes the light-receiving surface 17-1 more effectively cleaned after the entire two-way snow remover moves and cleans.

[0080] See Figure 1 and Figure 4 When the snow accumulation is thick, the excess snow leaks through the mesh on the snow shovel 2 onto the snow wiping component 1. After the snow shovel 2 shovels the snow on the snow-facing side, the snow wiping component 1 makes a second contact with the photovoltaic module 17, and completes the second snow wiping through the snow wiping component 1, so that the snow that is in contact with the light-receiving surface 17-1 of the photovoltaic module 17 is removed together with the snow that leaked through the snow shovel 2 on the snow-facing side.

[0081] In some embodiments, see Figure 1 and Figure 4The snow shovel 2 is a flat, plate-like structure, and the angle between the snow shovel 2 and its moving direction in the first direction is an obtuse angle. Thus, as the snow shovel 2 is pushed forward in the first direction, snow gradually accumulates in front of it. Because of the obtuse angle, the snow has a certain obstructing and guiding effect on the snow shovel 2, allowing it to better gather in front of the shovel. When a certain amount has accumulated, under the influence of gravity, the snow is more likely to fall off the edge of the roof, improving the efficiency of snow removal. Compared to acute and right angles, this reduces the resistance of the snow shovel 2.

[0082] As a parallel embodiment, the angle between the snow shovel 2 and the snow scraping direction can be an acute angle or a right angle. An acute angle is conducive to snow gathering, a right angle can achieve uniform snow scraping, and an obtuse angle is convenient to scrape snow off the roof in specific situations. The upper end of the snow shovel 2 extends upward to ensure that there is enough height to accommodate and guide the snow.

[0083] In this embodiment, both the snow scraper 1 and the snow shovel 2 are mesh structures made of the same material, and both the snow scraper 1 and the snow shovel 2 are fixed to the snow scraper frame 3 by wrapping. The material of the snow scraper 1 and the snow shovel 2 can be EPE. Both the snow scraper 1 and the snow shovel 2 are fixed to the snow scraper frame 3 by a fixing structure, which can be a positioning post, a bolt and nut structure, or wire wrapping, etc.

[0084] In practical use, since the photovoltaic modules 17 are arranged in an array, there are essentially multiple photovoltaic modules 17 closely arranged along the first direction. Each photovoltaic module 17 has a corresponding frame on its light-receiving surface 17-1, and there is a certain height difference between the frame and the glass of the light-receiving surface 17-1, such as 3mm. There is a certain gap on the light-receiving surface 17-1 of adjacent photovoltaic modules 17, such as 2cm. Therefore, based on the above gaps or height differences, the bidirectional snow remover will shake a certain amount when it moves to this position, which is conducive to shaking the snow off the photovoltaic modules 17.

[0085] When continuously clearing snow from an array of photovoltaic modules 17: Existing unidirectional snow removal devices, after clearing snow from a row of closely arranged photovoltaic modules 17, require manual labor to lift the snow removal device from the end of the previous row of photovoltaic modules 17 back to the beginning of the next row of photovoltaic modules 17; This application can move snow removal in two opposite directions along the first direction, and after clearing snow from the beginning to the end of the previous row of photovoltaic modules 17, it can directly clear snow from the end to the beginning of the next row of photovoltaic modules 17.

[0086] Therefore, when applied to a 20MW photovoltaic power plant with 1806 arrays: using existing unidirectional snow removal equipment, it is estimated that 32 people and 16 snow removers would be needed to clear the snow within 2 hours; using the bidirectional snow remover of this application, most of the time required for personnel to carry tools is saved, and the snow removal efficiency is approximately twice that of the existing equipment. Conservatively estimated, 20 people and 10 snow removers can clear 20MW of photovoltaic modules within 2 hours.17 In comparison, the device of this application reduces the number of employees, lowers labor costs, and also reduces the number of snow removal devices required, thus reducing tool costs.
