DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1-8 As shown, the technical solution adopted by the present invention is as follows: A photovoltaic module device includes a horizontally positioned base plate 1. A base plate 5 is mounted on the base plate 1 and is parallel to the base plate 1. An inclined plate 10 is rotatably mounted above the base plate 5. Photovoltaic panels 36 are laid on the inclined plate 10. Multiple photovoltaic panels 36 are provided, and the multiple photovoltaic panels 36 are evenly laid on the inclined plate 10. The photovoltaic panels 36 are electrically connected to a power storage device. Power storage devices are common knowledge in the art and will not be described in detail here.

[0021] The base plate 5 is rotatably connected to the bottom plate 1. The base plate 5 rotates around the bottom plate 1, driving the tilting plate 10 and the photovoltaic panel 36 to rotate together, and can adjust the angle of the photovoltaic panel 36 in the horizontal plane so that the photovoltaic panel 36 can face the direction of sunlight.

[0022] Specifically, a first motor 2 is fixedly mounted on the base plate 1. The axis of the output shaft of the first motor 2 is arranged horizontally. A worm 3 is coaxially fixedly mounted on the output shaft of the first motor 2. A vertical fixed shaft is rotatably mounted on the base plate 1. The upper end of the fixed shaft is fixedly connected to the base plate 5. A worm gear 4 is fixedly mounted on the fixed shaft and meshes with the worm 3.

[0023] When the horizontal angle of the photovoltaic panel 36 needs to be adjusted, the first motor 2 is activated. This drives the worm 3, which, through engagement with the worm gear 4, drives the base plate 5 to rotate synchronously. As the base plate 5 rotates, the tilting plate 10 and the photovoltaic panel 36 also rotate, allowing for convenient adjustment of the horizontal angle of the photovoltaic panel 36.

[0024] One end of the tilting plate 10 is rotatably connected to the corresponding end of the base plate 5. Specifically, a horizontally arranged rotating shaft is fixedly installed at the end of the base plate 5, and a rotating seat is fixedly installed at the lower end of the tilting plate 10, and the rotating seat is rotatably connected to the rotating shaft.

[0025] The tilting plate 10 rotates around the end of the base plate 5 to adjust the inclination of the tilting plate 10 relative to the base plate 5, thereby adjusting the inclination of the photovoltaic panel 36. The inclination of the photovoltaic panel 36 can be adjusted according to the angle of sunlight, so that sunlight can be perpendicular to the photovoltaic panel 36, thereby improving the light energy absorption efficiency of the photovoltaic panel 36.

[0026] Furthermore, an adjustment structure for adjusting the tilt angle of the tilt plate 10 is installed between the tilt plate 10 and the base plate 5 .

[0027] Specifically, the adjustment structure includes a threaded rod 7 , a hinge block 8 and a hinge plate 9 .

[0028] A second motor 6 is fixedly mounted on the end of the base plate 5 away from the rotating shaft. The axis of the output shaft of the second motor 6 is arranged horizontally. The axis of the output shaft of the second motor 6 is perpendicular to the axis of the rotating shaft. The threaded rod 7 is fixedly connected to the output shaft of the second motor 6.

[0029] A horizontal guide groove is formed at the upper end of the base plate 5. The length direction of the guide groove is parallel to the axis of the threaded rod 7. The hinge block 8 is slidably connected to the guide groove. The hinge block 8 is threadedly connected to the threaded rod 7.

[0030] A hinge seat is fixedly mounted on the bottom of the tilting plate 10. One end of the hinge plate 9 is hinged to the hinge block 8. The other end of the hinge plate 9 is hinged to the hinge seat.

[0031] When the tilt angle of the tilt plate 10 needs to be adjusted, the second motor 6 is activated. This second motor 6 drives the threaded rod 7 to rotate. Because the hinge block 8 and the threaded rod 7 are threadedly connected, and the hinge block 8 and the base plate 5 are slidingly connected, the threaded rod 7 and the hinge block 8 form a ball screw structure. The rotation of the threaded rod 7 drives the hinge block 8 to slide along the guide groove.

[0032] When the hinge block 8 moves toward the direction of the rotating seat, the hinge plate 9 pushes the tilting plate 10 to rotate in the direction of increasing the angle between the hinge block 8 and the base plate 5; conversely, when the hinge block 8 moves away from the rotating seat, the hinge plate 9 pushes the tilting plate 10 to rotate in the direction of decreasing the angle between the hinge block 8 and the base plate 5. Figure 3 As shown, when the hinge block 8 moves toward the rotating seat, the tilting plate 10 drives the photovoltaic panel 36 to rotate counterclockwise, so that the angle between the tilting plate 10 and the substrate 5 increases; when the hinge block 8 moves away from the rotating seat, the tilting plate 10 drives the photovoltaic panel 36 to rotate clockwise, so that the angle between the tilting plate 10 and the substrate 5 decreases.

[0033] A snow scraper 14 is slidably mounted on the inclined plate 10. The snow scraper 14 and the photovoltaic panel 36 are perpendicular to each other, and the lower end of the snow scraper 14 contacts the upper end surface of the photovoltaic panel 36. The sliding direction of the snow scraper 14 is parallel to the tilt direction of the inclined plate 10.

[0034] When the snow scraper 14 slides, the snow scraper 14 scrapes off the ice and snow covering the photovoltaic panel 36 .

[0035] Specifically, the inclined plate 10 includes a first vertical plate and a first horizontal plate. The first vertical plate is fixed to the end of the first horizontal plate. The first horizontal plate and the first vertical plate give the inclined plate 10 an overall L-shape. The photovoltaic panel 36 is placed on the first horizontal plate. A third motor 11 is fixedly mounted on the first vertical plate. The axis of the third motor 11 is parallel to the length of the first vertical plate. A screw rod 12 is coaxially fixedly mounted on the third motor 11 and is located within the first vertical plate. The end of the screw rod 12, distal from the third motor 11, is rotatably connected to the first vertical plate. A movable block 13 is threadedly connected to the screw rod 12. The movable block 13 is slidably connected to the first vertical plate. The movable block 13 is fixedly connected to a snow scraper 14. The screw rod 12 and movable block 13 also form a ball screw structure. When the third motor 11 is activated, it drives the screw rod 12 to rotate, which in turn drives the movable block 13 and the snow scraper 14 to move along the screw rod 12, thereby enabling the snow scraper 14 to scrape ice and snow from above the photovoltaic panel 36.

[0036] One side of the snow scraper 14 is connected with a connecting plate 22 which is parallel to the snow scraper 14. Specifically, the moving block 13 is fixedly connected to the connecting plate 22 at the same time.

[0037] A snow removal plate 21 is slidably mounted on the snow scraper 14. The sliding direction of the snow removal plate 21 is perpendicular to the sliding direction of the snow scraper 14. The snow removal plate 21 slides to remove the ice and snow adhered to the snow scraper 14.

[0038] Specifically, a sliding plate 15 is slidably mounted on the snow scraper 14. The sliding plate 15 includes a second transverse plate and a second vertical plate. The second vertical plate is fixedly connected to the second transverse plate. The second transverse plate is located above the snow scraper 14. The second vertical plate is located on the side of the snow scraper 14 away from the connecting plate 22. The snow removal plate 21 is connected to the second vertical plate of the sliding plate 15. A chute 18 is provided on the snow scraper 14 near the second transverse plate of the sliding plate 15. A slider 17 is fixedly mounted on the second transverse plate of the sliding plate 15 and is slidably connected to the chute 18.

[0039] When the sliding plate 15 drives the snow scraper 14 to slide along the slide groove 18 , the snow removal plate 21 removes the ice and snow adhering to the snow scraper 14 .

[0040] Furthermore, a fourth motor 16 is fixedly mounted on the connecting plate 22, a second rotating plate 20 is fixedly mounted on the output shaft of the fourth motor 16, a first rotating plate 19 is rotatably mounted on the slider 17, and the end of the first rotating plate 19 away from the slider 17 is hinged to the end of the second rotating plate 20 away from the fourth motor 16.

[0041] The fourth motor 16 is started, and the fourth motor 16 drives the second rotating plate 20 to rotate together. The second rotating plate 20 rotates and drives the sliding plate 15 to reciprocate along the slide groove 18 through the first rotating plate 19. The reciprocating movement of the sliding plate 15 drives the snow removal plate 21 to reciprocate, and the reciprocating movement of the snow removal plate 21 clears ice and snow from the snow scraper 14.

[0042] Two groups of heating components are provided at the bottom of the connecting plate 22. Two slot plates 27 are mounted on the connecting plate 22. The slot plates 27 correspond one-to-one with the heating components and are connected to the corresponding heating components. The slot plates 27 are slidably connected to the connecting plate 22. The sliding direction of the slot plates 27 is perpendicular to the sliding direction of the snow scraper 14. The reciprocating movement of the slot plates 27 causes the heating components to intermittently heat the photovoltaic panels 36. A wiper blade 28 is vertically slidably mounted on each of the slot plates 27. The sliding direction of the wiper blade 28 is perpendicular to the sliding direction of the slot plates 27.

[0043] The heating assembly heats the photovoltaic panel 36 to quickly melt the ice and snow on the photovoltaic panel 36. The wiper blade 28 scrapes away the melted ice or snow on the photovoltaic panel 36.

[0044] A first driving structure is installed between the wiper plate 28 and the connecting plate 22. The first driving structure drives the slot plate 27 to move back and forth, and the reciprocating movement of the slot plate 27 causes the heating assembly to intermittently heat the photovoltaic panel 36.

[0045] When the two slot plates 27 move away from each other, the first drive structure places the wiper blade 28 in its lowest displacement position, where the lower end of the wiper blade 28 is in close contact with the upper end of the photovoltaic panel 36. The wiper blade 28 moves away from the slot plates 27, scraping away accumulated water on the photovoltaic panel 36 and ensuring that the accumulated water is effectively removed.

[0046] When the two slot plates 27 move toward each other, the first drive structure drives the wiper blade 28 to slide along the slot plates 27 and break contact with the photovoltaic panel 36. At this time, the wiper blade 28 no longer contacts the upper end surface of the photovoltaic panel 36 during the process of moving away from each other, and will not scrape the accumulated water inward, thereby preventing the accumulated water from being scraped back to the surface of the photovoltaic panel.

[0047] Each heating assembly includes an air bag 31 , an air intake pipe 32 and an air outlet pipe 33 .

[0048] A connecting groove 30 is fixedly mounted on the bottom of the connecting plate 22. The airbag 31 is mounted within the connecting groove 30. The expansion and contraction direction of the airbag 31 is parallel to the sliding direction of the retaining plate 27. A compression plate 29 is fixedly mounted on the bottom of the retaining plate 27. The compression plate 29 slides within the connecting groove 30 and is fixedly connected to the airbag 31.

[0049] An air inlet and an air outlet are provided on the air bag 31. An air inlet valve is installed on the air inlet, and an air outlet valve is installed on the air outlet.

[0050] The air intake pipe 32 is connected to the air inlet of the airbag 31. The air outlet pipe 33 is connected to the air outlet of the airbag 31. A heating plate 34 is installed in the air outlet pipe 33. The heating plate 34 is installed in the air outlet pipe 33 near the air outlet.

[0051] The axis of the air outlet pipe 33 is parallel to the expansion and contraction direction of the airbag 31. The air outlet pipe 33 is provided with a plurality of air outlet holes 35 with openings facing the photovoltaic panel 36.

[0052] As attached Figure 7 As shown, when the first drive mechanism drives the retaining plate 27 via the wiper blade 28, deflating the airbag 31, the gas within the airbag 31 is heated by the heating plate 34 and discharged through the air outlet 35. At this point, the heating assembly heats the photovoltaic panel 36. In this state, the two retaining plates 27 move away from each other, and the wiper blade 28 is at its lowest position, with its lower end in contact with the photovoltaic panel 36. The first drive mechanism drives the wiper blade 28 to move, scraping away melted snow from above the photovoltaic panel 36, ensuring a clean surface.

[0053] When the first drive mechanism drives the retaining plate 27 via the wiper blade 28, causing the airbag 31 to inhale, the air outlet 35 stops releasing hot air, and the heating assembly also stops heating. At this point, the two retaining plates 27 move toward each other, and the wiper blade 28 slides vertically upward along the retaining plates 27, breaking contact with the photovoltaic panel 36. This prevents melted snow from being scraped back onto the surface of the photovoltaic panel 36, thereby preventing it from affecting normal operation.

[0054] A mounting cavity is defined in the connecting plate 22. The first driving structure is mounted in the mounting cavity.

[0055] As an optional embodiment, the first driving structure includes: a pulley 24 , a synchronous belt 25 and a connecting rod 26 .

[0056] The axis of the pulley 24 is perpendicular to the connecting plate 22. There are three pulleys 24. The axes of the three pulleys 24 are connected to form an isosceles triangle. A fifth motor 23 is coaxially fixedly mounted on one of the pulleys 24.

[0057] The synchronous belt 25 is sleeved on the pulley 24 .

[0058] The connecting rod 26 is fixedly mounted on the side of the synchronous belt 25. The slot plate 27 is provided with a vertical slot. The connecting rod 26 is slidably connected to the vertical slot. The wiper 28 is fixedly connected to the connecting rod 26.

[0059] When the connecting rod 26 moves with the timing belt 25 to the base of the isosceles triangle, the timing belt 25 drives the connecting rod 26 along the base of the isosceles triangle. At this point, the connecting rod 26 drives the extrusion plate 29 through the slot plate 27 to move toward the extrusion airbag 31, that is, the two extrusion plates 29 move away from each other. The extrusion plate 29 applies pressure to the airbag 31, and the gas inside the airbag 31 is heated by the heating plate 34 and discharged from the air outlet 35. The heating assembly heats the photovoltaic panel 36. At this point, the connecting rod 26 is located at the lowest end of the vertical groove on the slot plate 27, and the lower end of the wiper plate 28 contacts the upper end surface of the photovoltaic panel 36. As the connecting rod 26 moves, the wiper plate 28 pushes the melted snow water on the photovoltaic panel 36 outward.

[0060] As attached Figure 7As shown, when the wiper blade 28 reaches its outermost position, the airbag 31 is in its squeezed extreme position. Subsequently, as the timing belt 25 moves, the connecting rod 26 moves along the waist of the isosceles triangle. During this process, the connecting rod 26 slides along the vertical groove of the retaining plate 27, driving the retaining plate 27 in the opposite direction. The retaining plate 27 moves the squeezing plate 29, increasing the volume of the airbag 31 and allowing ambient air to enter the airbag 31 through the intake pipe 32. At this point, the wiper blade 28 loses contact with the upper end surface of the photovoltaic panel 36, preventing the wiper blade 28 from pushing accumulated water from the panel 36 toward the center.

[0061] During this process, the motion trajectory of wiper blade 28 aligns with the isosceles triangle formed by the connecting axes of the three pulleys 24. The movement of wiper blade 28 simultaneously drives reciprocating motion of extrusion plate 29, causing the volume of airbag 31 to fluctuate periodically. Ambient air is drawn into airbag 31, then discharged through outlet pipe 33. After being heated by heating plate 34, it is discharged through outlet 35, heating the ice and snow on photovoltaic panel 36 and causing it to melt.

[0062] As another optional embodiment, the first drive assembly includes a first electric telescopic rod and a second electric telescopic rod, the axes of which are perpendicular to each other. The telescopic direction of the first electric telescopic rod is parallel to the direction of movement of the slot plate. The first electric telescopic rod is fixed to the connecting plate 22, and the telescopic end of the first electric telescopic rod is fixedly connected to the slot plate 27. The second electric telescopic rod is fixed to the slot plate 27, and the telescopic end of the second electric telescopic rod is fixedly connected to the wiper blade 28. In this embodiment, the first electric rod and the second electric rod are both common knowledge to those skilled in the art. They are not shown in the drawings.

[0063] The first electric telescopic rod and the second electric telescopic rod are configured to meet the following action process.

[0064] When the first electric telescopic rod drives the slot plate 27 to move outward, that is, when the two slot plates 27 move away from each other, the second electric telescopic rod makes the bottom of the wiper blade 28 contact the photovoltaic panel 36, and the wiper blade 28 moves together with the slot plate 27, and the wiper blade 28 scrapes the accumulated water of melted ice and snow on the photovoltaic panel 36 outward.

[0065] When the first electric telescopic rod drives the slot plate 27 to move inward, that is, when the two slot plates 27 move toward each other, the second electric telescopic rod causes the bottom of the wiper blade 28 to separate from the photovoltaic panel 36, and the wiper blade 28 moves together with the slot plate 27. The wiper blade 28 does not contact the photovoltaic panel 36, which can prevent the wiper blade 28 from scraping the accumulated water melted by ice and snow on the photovoltaic panel 36 inward.

[0066] The specific operating principle of the present invention is as follows: The first motor 2 is started, which drives the worm 3 to rotate. The worm 3, through engagement with the worm gear 4, drives the base plate 5 to rotate together. The rotation of the base plate 5 drives the tilting plate 10 and the photovoltaic panel 36 to rotate together, adjusting the angle of the photovoltaic panel 36 in the horizontal plane so that the photovoltaic panel 36 is aligned with the direction of sunlight to optimize light energy absorption efficiency.

[0067] According to the solar radiation angle of the photovoltaic panel 36 in the installation area, the inclination angle of the photovoltaic panel 36 is adjusted to ensure that the sunlight can be vertically irradiated on the photovoltaic panel 36.

[0068] The specific adjustment method is as follows: start the second motor 6. The rotation of the second motor 6 drives the threaded rod 7 to rotate together. The rotation of the threaded rod 7 drives the hinge block 8 to slide along the guide groove. When the hinge block 8 moves toward the rotating base, it pushes the tilting plate 10 through the hinge plate 9 to rotate in a direction that increases the angle between the tilting plate 10 and the base plate 5. When the hinge block 8 moves away from the rotating base, it pushes the tilting plate 10 through the hinge plate 9 to rotate in a direction that decreases the angle between the tilting plate 10 and the base plate 5.

[0069] When it is necessary to clean the ice and snow on the photovoltaic panel 36, the third motor 11 is started, the third motor 11 drives the screw rod 12 to rotate, and the screw rod 12 drives the moving block 13 and the snow scraper 14 to move along the screw rod 12, so that the snow scraper 14 can scrape the ice and snow above the photovoltaic panel 36.

[0070] At the same time, the fifth motor 23 is started, driving the synchronous belt 25 via the pulley 24. When the connecting rod 26 moves with the synchronous belt 25 to the base of the isosceles triangle, the synchronous belt 25 drives the connecting rod 26 along the base of the isosceles triangle. At this point, the connecting rod 26 drives the extrusion plate 29 via the slot plate 27 toward the airbag 31. That is, the two extrusion plates 29 move away from each other. The extrusion plates 29 squeeze the airbag 31, and the gas inside the airbag 31 is heated by the heating plate 34 and discharged from the air outlet 35. The heating assembly heats the photovoltaic panel 36. At this point, the connecting rod 26 is located at the lowest end of the vertical groove on the slot plate 27. The lower end of the wiper blade 28 contacts the upper end surface of the photovoltaic panel 36. The wiper blade 28 moves with the connecting rod 26, pushing the melted snow off the photovoltaic panel 36.

[0071] As attached Figure 7As shown, when the wiper blade 28 moves to its outermost position, the airbag 31 is in its squeezed extreme position. As the synchronous belt 25 moves, it drives the connecting rod 26 along the side of the isosceles triangle. During this process, the connecting rod 26 slides along the vertical groove of the retaining plate 27, while simultaneously driving the retaining plate 27 in the opposite direction. The retaining plate 27 drives the extrusion plate 29 to move, which increases the volume of the airbag 31 and allows air to enter the airbag 31 from the intake pipe 32. During this process, the wiper blade 28 disengages from the upper end surface of the photovoltaic panel 36, preventing the wiper blade 28 from pushing accumulated water from the photovoltaic panel 36 to the middle of the panel 36.

[0072] Alternatively, the first electric telescopic rod is activated, driving the retaining plate 27 outward. This causes the two retaining plates 27 to move away from each other. This in turn drives the extrusion plate 29 toward the airbag 31. This causes the two extrusion plates 29 to move away from each other. The extrusion plate 29 compresses the airbag 31, and the gas within the airbag 31 is heated by the heating plate 34 and discharged from the air outlet 35. The heating assembly heats the photovoltaic panel 36. Simultaneously, the second electric telescopic rod is adjusted, causing the bottom of the wiper blade 28 to contact the photovoltaic panel 36. The wiper blade 28 moves with the retaining plate 27, scraping away the accumulated water from the melted ice and snow on the photovoltaic panel 36.

[0073] When the first electric telescopic rod drives the slot plates 27 inward, that is, when the two slot plates 27 move toward each other, the slot plates 27 drive the extrusion plates 29 to move. This movement increases the volume of the airbag 31, and gas enters the airbag 31 through the suction pipe 32. At the same time, the second electric telescopic rod is activated to separate the bottom of the wiper blade 28 from the photovoltaic panel 36. The wiper blade 28 moves along with the slot plates 27, and does not contact the photovoltaic panel 36, preventing the wiper blade 28 from pushing accumulated water on the photovoltaic panel 36 to the middle.

[0074] When ice and snow adhere to the snow scraper 14 and need to be cleared, the fourth motor 16 is started, which drives the second rotating plate 20 to rotate together. The second rotating plate 20 rotates and drives the sliding plate 15 to reciprocate along the chute 18 via the first rotating plate 19. The reciprocating movement of the sliding plate 15 drives the snow removal plate 21 to reciprocate, and the reciprocating movement of the snow removal plate 21 removes the ice and snow on the snow scraper 14.
