DETAILED DESCRIPTION

[0024] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application are clearly and completely described below. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0025] As shown in Figure 1 and Figure 2 , the present application discloses a photovoltaic panel snow remover, which comprises a first end box 1 and a second end box 2 connected together, two parallel supporting rotating shafts 3 are arranged between the lower end of the first end box 1 and the lower end of the second end box 2, and a number of moving wheels 4 are arranged on the supporting rotating shafts 3.

[0026] The two ends of the supporting rotating shafts 3 are movably connected with the first end box 1 and the second end box 2, a driving unit 5 is arranged in the first end box 1, and the driving unit 5 can drive the two supporting rotating shafts 3 to rotate synchronously.

[0027] An air outlet is formed in the lower side of an air outlet pipe 6 arranged between the middle position of the first end box 1 and the middle position of the second end box 2 along the length direction of the air outlet pipe 6, a hot air assembly 7 is arranged in the second end box 2 and connected with the air outlet pipe 6, and the hot air assembly 7 can blow hot air into the air outlet pipe 6.

[0028] In the above embodiments, the first end box 1 and the second end box 2 connected together can form the main body of the whole device, the driving unit 5 arranged in the first end box 1 can drive the supporting rotating shafts 3 connected rotatably between the first end box 1 and the second end box 2 to rotate with the moving wheels 4 arranged thereon, so that the whole device of the present application can automatically adjust the position on the surface of the photovoltaic panel. The hot air assembly 7 arranged in the second end box 2 is connected with the air outlet pipe 6 between the first end box 1 and the second end box 2, when the hot air assembly 7 works, the generated hot air can be blown into the air outlet pipe 6 and then discharged from the air outlet.

[0029] The outdoor concentrated photovoltaic power generation system is usually composed of multiple rows of photovoltaic panels, and each row of photovoltaic panels includes multiple single photovoltaic panels arranged side by side. The snow remover of the present application can be placed on the outermost photovoltaic panel in a row when in use. When snowfall causes snow accumulation on the surface of the photovoltaic panel, the driving unit 5 in the first end box 1 will drive the support shaft 3 and the moving wheels 4 thereon to rotate. The moving wheels 4 will change the position of the entire device on the photovoltaic panel in real time during the rotation process. The hot air generated by the hot air assembly 7 in the second end box 2 will blow away the snow on the surface of the photovoltaic panel through the air outlet of the air outlet pipe 6. The wind force and heat of the hot air will act on the snow together after contacting the snow on the photovoltaic panel. The wind force will blow away the loose snowflakes in the snow, and the wind force will also bring heat to quickly contact and exchange heat with the snow to melt it away. The snowflakes near the surface of the snow are usually loose, which can be easily blown away by the wind force. The remaining part of the snow contains a layer of ice that is tightly combined with the photovoltaic panel. When the heat in the hot air contacts the ice layer, the ice layer will gradually melt and heat up, exposing the surface of the photovoltaic panel again. Compared with the traditional method of using workers to clean the snow on the surface of the photovoltaic panel with a scraper or a special broom, the present application not only saves time and effort, but also effectively deals with the snow and ice layer that is difficult to clean with a scraper or a broom.

[0030] Further, as shown in Figure 1 and Figure 4 , a set of side guide wheels 8 is installed on the lower end of the first end box 1 and the second end box 2 away from each other, and the distance between the two sets of side guide wheels 8 is the same as the length of the long side of the single photovoltaic panel to be cleaned. The wheels of the side guide wheels 8 are in the same plane as the plane of the photovoltaic panel to be cleaned when in use.

[0031] In the above embodiment, the side guide wheels 8 provided on the mutually distant sides of the first end box 1 and the second end box 2 can provide a guiding effect during the movement of the entire device to ensure that the device moves in a straight line, facilitating comprehensive cleaning of the entire row of photovoltaic panels. Moreover, in order to increase the contact time with sunlight, the photovoltaic panel is usually inclined. For such an inclined photovoltaic panel, the side guide wheels 8 in contact with the high end of the photovoltaic panel can also limit the entire device from shifting in the long direction of the photovoltaic panel to prevent the device from sliding off the surface of the photovoltaic panel in the length direction.

[0032] Further, as shown in Figure 1 , Figure 2 and Figure 4As shown, the protection cover 9 is fixedly sleeved on the air outlet pipe 6, and the number of the protection cover 9 is same as the number of the moving wheels 4 on the single support shaft 3. The first end box 1 and the second end box 2 and the adjacent protection cover 9, and the protection cover 9 and the adjacent protection cover 9 are fixedly connected through the plurality of square tubes 10. The moving wheels 4 of the two support shafts 3 located at the same position along the axial direction are located in the same protection cover 9, and the two support shafts 3 penetrate through the protection cover 9 and are rotationally connected with the protection cover 9.

[0033] In the above embodiment, the protection cover 9 outside the moving wheel 4 can play a certain protection role. The first end box 1 and the second end box 2 and the adjacent protection cover 9, and the protection cover 9 and the adjacent protection cover 9 are connected through the plurality of square tubes 10, so that the first end box 1 and the second end box 2 form a stable overall structure. The support shaft 3 and the part of the air outlet pipe 6 between the first end box 1 and the second end box 2 are also supported by the protection cover 9, so that they can obtain uniform support force during use, thereby avoiding the risk of deformation due to the too long overhanging section.

[0034] Further, as shown in Figure 2 and Figure 3 , the driving unit 5 includes two transmission gears 51, the two transmission gears 51 are fixedly sleeved on the part of the two support shafts 3 located in the first end box 1, and the two transmission gears 51 are connected through a toothed belt 52. One side of the transmission gear 51 on one of the support shafts 3 is fixedly sleeved with a power transmission gear 53, the upper side of the power transmission gear 53 is engaged with a power output gear 54, the center of the power output gear 54 penetrates an installation shaft 55, one end of the installation shaft 55 is fixedly connected with the inner wall of the first end box 1, the other end of the installation shaft 55 is sleeved with a support rod 56 and rotationally connected with the support rod 56, the end of the installation shaft 55 close to the second end box 2 penetrates through the support rod 56 and is fixedly connected with the output end of a driving motor 57, the driving motor 57 and the support rod 56 are fixedly installed on the inner wall of the first end box 1.

[0035] In the above embodiment, when the driving motor 57 works, the power output gear 54 can be rotated through the output shaft connected with the output end of the driving motor 57, the lower side of the power output gear 54 is engaged with the power transmission gear 53, so that the power transmission gear 53 rotates synchronously with the power output gear 54, and the power transmission gear 53 transmits the force from the power output gear 54 to the support shaft 3 at the installation position of the power transmission gear 53, so that the support shaft 3 rotates with the transmission gear 51 on it, and the transmission gears 51 on the two support shafts 3 are connected through the toothed belt 52, so that the two support shafts 3 can rotate synchronously in the same direction when the driving motor 57 works, and the moving wheels 4 on the two support shafts 3 can be driven to move on the surface of the photovoltaic panel, so that the whole device can be moved, which is simple and convenient to use.

[0036] Further, as shown inFigure 2 and Figure 4 As shown, the hot air assembly 7 includes a heating sleeve 71. One end of the air outlet pipe 6 is open along its length. The open end of the air outlet pipe 6 passes through the inner wall of the second end box 2 near the first end box 1 and is fixedly connected to one end of the heating sleeve 71. A heating wire is installed inside the heating sleeve 71 (the heating wire inside the heating sleeve 71 in this application is not shown in the attached drawings). The other end of the heating sleeve 71 is connected to the air outlet of the axial flow fan 72. The housing of the axial flow fan 72 is fixedly installed on the inner wall of the second end box 2. A vent 73 is provided on the side wall of the second end box 2 away from the first end box 1 at a position opposite to the air inlet of the axial flow fan 72. The axial flow fan 72 can draw in air from the environment through the vent 73.

[0037] In the above embodiments, the heating wire in the heating sleeve 71 generates heat when energized, and the axial flow fan 72 connected to the heating sleeve 71 can draw in air from the ventilation port 73 of the second end box 2 during operation, and then blow it toward the open end of the air outlet 6. Before entering the air outlet 6, the airflow will first flow through the heating wire in the heating sleeve 71. Therefore, after the airflow obtains heat at the heating wire, it will become the hot air required by this application. After the hot air enters the air outlet 6, it will be sprayed out from the air outlet opened in the direction of the photovoltaic panel, thereby achieving a better snow removal effect on the surface of the photovoltaic panel.

[0038] Furthermore, a temperature sensor is installed at the air outlet of the air outlet 6, and the temperature sensor is electrically connected to the control module of the heating wire inside the heating sleeve 71 (the temperature sensor and the control module of the heating wire in this application are not shown in the drawings).

[0039] In the above embodiments, the temperature sensor installed at the air outlet of the air outlet 6 can monitor the actual temperature of the hot air in real time and feed the measured information back to the control module of the heating wire so that the control module of the heating wire can adjust the heat generation of the heating wire, thereby intelligently controlling the temperature of the blown air, ensuring that the temperature blown onto the surface of the photovoltaic panel is not too low to affect the snow removal effect, nor too high to damage the surface of the photovoltaic panel.

[0040] Furthermore, such as Figure 5 As shown, multiple grille air guide plates 11 are evenly arranged inside the air outlet duct 6 along its length, and the upper ends of the grille air guide plates 11 are all inclined towards the second end box 2.

[0041] In the above embodiment, the axial flow fan 72 is directly opposite the air outlet pipe 6, so that if the air blown by the axial flow fan 72 is not controlled, most of the air will flow downward after hitting the closed port of the air outlet pipe 6, which will cause the air outlet of the air outlet pipe 6 to be uneven, and the grid air guide plate 11 arranged in the air outlet pipe 6 can make part of the hot air flow downward in advance when the hot air passes through, which can effectively improve the uniformity of the air outlet of the air outlet pipe 6, so as to ensure that the cleaning effect of different areas of the photovoltaic panel surface is as consistent as possible.

[0042] Further, as shown in Figure 1 , a plurality of snow turning units 12 are installed on the plurality of square tubes 10 at the same height on one side of the lower end of the first end box 1 and the second end box 2, and the snow turning units 12 can loosen the snow on the surface of the photovoltaic panel to be cleaned during movement.

[0043] In the above embodiment, the snow turning units 12 arranged on the plurality of square tubes 10 at the same height on one side of the lower end of the first end box 1 and the second end box 2 can first contact the snow before the air outlet pipe 6, and the snow turning units 12 loosen the snow on the surface of the photovoltaic panel in advance, so that the hot air sprayed by the subsequent air outlet pipe 6 can more easily remove the snow.

[0044] Further, as shown in Figure 1 , the snow turning unit 12 includes a fixed rod 121, the upper end of the fixed rod 121 is fixedly connected with the square tube 10, and the lower end of the fixed rod 121 is fixedly connected with a plastic plow plate 122.

[0045] In the above embodiment, the plastic plow plate 122 of the snow turning unit 12 of the present application is similar in shape to the plow head in the plow, and when the plastic plow plate 122 passes through the snow, it can efficiently turn up the snow by using the plow surface with a certain slope, so that the snow is loosened and the hot air sprayed by the subsequent air outlet pipe 6 can be cleaned. The material of the plastic plow plate 122 of the present application is plastic, and its hardness is less than that of the polysilicon on the surface of the photovoltaic panel, so that the plastic plow plate 122 can prevent the photovoltaic panel from being scratched during snow turning.

[0046] The implementation principle of the embodiment is that when the snow on the surface of the photovoltaic panel needs to be cleaned, the driving motor 57 in the first end box 1 can drive the support shaft 3 to rotate, so that the moving wheel 4 on the support shaft 3 moves on the surface of the photovoltaic panel. The airflow in the second end box 2 of the axial flow fan 72 blows to the air outlet of the air outlet pipe 6, and the airflow in the air outlet pipe 6 is heated in the heating sleeve 71 before entering the air outlet pipe 6, so that the airflow entering the air outlet pipe 6 becomes hot air. These hot air can blow to the snow on the surface of the photovoltaic panel in real time through the air outlet of the air outlet pipe 6. After the hot air contacts the snow on the surface of the photovoltaic panel, part of the loose snow is directly blown away by the wind. Another part of the ice layer combined with the snow at the bottom of the photovoltaic panel is tightly contacted with the hot air, and the ice layer is melted by heat exchange with the hot air. When the snow remover moves from one end of a row of photovoltaic panels to the other end, the snow cleaning work on the row of photovoltaic panels is also completed synchronously. Compared with the way of cleaning the snow on the surface of the photovoltaic panel by the worker through the scraper or the special broom, the application not only saves time and effort, but also can remove the ice layer at the bottom of the snow without damaging the surface of the photovoltaic panel.

[0047] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the application, but not to limit them; although the application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can modify the technical solutions described in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the application.
