Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation devices, and particularly to a large-scale industrial photovoltaic power generation device that automatically follows sunlight. Background Art

[0002] With the rapid development of the new energy industry, solar energy, as the most important basic energy among various renewable energies, its solar power generation technology, i.e., the photovoltaic industry, has developed rapidly. Among them, the bracket in the photovoltaic power generation component is the bracket used to support the solar panel in the solar photovoltaic power generation system. The inclination of the solar panel can be adjusted by adjusting its fasteners to adapt to different angles of light, thereby improving the conversion efficiency of solar energy. Although the existing photovoltaic brackets that can automatically adjust the inclination angle of the solar panel can adjust the inclination angle of the photovoltaic module in a timely manner according to external environmental factors, they mainly complete the adjustment work through the cooperation of various sensors. This will lead to its complex structure and high cost, and the complex structure is prone to failure under long-term exposure to the sun, resulting in a significant increase in maintenance costs and being not convenient for wide application.

[0003] To solve the above technical problems, a Chinese patent with the publication number of CN118017914A in the prior art discloses a self-adjusting flexible photovoltaic module, including a base, and further including: symmetrically arranged side plates, both fixedly connected to the upper end of the base. Among them, a rotating shaft is rotatably connected between the two side plates, and a support plate is fixedly installed on the rotating shaft. The front end face and the rear end face of the support plate are respectively fixedly installed with a main photovoltaic panel and a heat dissipation plate; a driving part is arranged on the side plate, and the driving part is used to drive the rotating shaft to rotate. Among them, a light irradiation adjusting component is arranged on the support plate, and the light irradiation adjusting component is used to control the driving part.

[0004] Although the above prior art solution can make the photovoltaic panel automatically deflect following the sunlight to complete the automatic angle adjustment work, when the solar panel is used outdoors, dust and impurities are extremely likely to adhere to its surface. After these impurities cover the surface of the solar panel, it will greatly affect the photoelectric conversion efficiency. Although it can use brushes to brush various parts, the multiple groups of brushes installed on it are fixedly arranged on the device, and it is difficult for the staff to remove the aged or overly adhered brushes for cleaning and maintenance, thus affecting the subsequent cleaning effect.

[0024] In addition, in this embodiment, the flipping assembly includes a torsion assembly and a positioning assembly. The torsion assembly includes a rotating rod 26 installed at one end of the damping rotating shaft 25. A docking plate 27 is rotatably connected to the outer side of the rotating rod 26. One side of the docking plate 27 is fixedly connected to one side of the outer wall of the placement seat. A reset groove is formed inside the docking plate 27 on the outer side of the rotating rod 26. A reset plate 28 is slidably connected to the inner side of the reset groove. First springs 29 are installed between both ends of one side of the reset plate 28 and the inner wall of the reset groove. The reset plate 28 is slidably connected to the rotating rod 26. A movable sleeve 30 is installed on one side of the reset plate 28. The movable sleeve 30 is slidably connected to the docking plate 27 and is also slidably connected to the rotating rod 26. The positioning assembly includes multiple groups of positioning holes formed on one side of the docking plate 27. A positioning post 31 is installed at the protruding end of the movable sleeve 30. The positioning post 31 is slidably connected to the positioning holes. A limiting groove is formed inside the movable sleeve 30 on one side of the rotating rod 26. A limiting block 32 slidably connected to the limiting groove is installed on one side of the rotating rod 26. A handle 33 is installed at the other end of the movable sleeve 30. A first magnetic member 34 is embedded at one end of the positioning post 31. A second magnetic member 35 that is adsorbed by the corresponding first magnetic member 34 is embedded on the inner wall of the positioning hole. An anti-slip sleeve is sleeved on the handle of the handle 33. The magnetic forces of the first magnetic member 34 and the second magnetic member 35 are opposite and attract each other. Hold the handle 33 at one end of the movable sleeve 30 and drive it to move. While the movable sleeve 30 is moving, it drives the reset plate 28 to compress the two first springs 29 to retract, so that the positioning post 31 disengages from the inner side of the positioning hole. Then, in cooperation with the limiting groove, the limiting block 32 and the damping rotating shaft 25, the positioning post 31 is driven to rotate. After rotating to a specified angle, the handle 33 can be loosened backward. The two first springs 29 are instantly reset, so that the positioning post 31 enters the positioning hole at the corresponding position. The first magnetic member 34 and the second magnetic member 35 are adsorbed to strengthen the positioning effect, and the rotated and adjusted angle is positioned, thereby realizing the flipping effect and facilitating the disassembly, installation, taking and placing of the sponge brush 57.

[0025] Further, in this embodiment, the quick-lock assembly includes a splicing plate 36 installed on one side of the outer wall of the sponge brush 57. A pressing block 37 is installed on one side of the splicing plate 36. A first rubber pad 38 is installed at the corresponding position of the placing seat on the side of the splicing plate 36. A connecting hole is formed inside the first rubber pad 38. A pressing groove is formed in the placing seat at the position corresponding to the connecting hole. The pressing groove is slidably connected to the pressing block 37. An operation groove is formed in the placing seat on one side of the pressing groove. A limiting seat 39 is installed on one inner wall side of the operation groove. A limiting groove is formed on one side of the limiting seat 39. A limiting plate 40 is slidably connected inside the limiting groove. A reset block 41 is installed at one end of the limiting plate 40. A second spring 42 is installed between one side of the limiting plate 40 and the inner wall of the limiting groove. The first rubber pad 38 is attached to one side of the splicing plate 36, so that the pressing block 37 slides into the inner side of the pressing groove, squeezing the brush plate 9 and the sponge brush 57, causing the first rubber pad 38 to be compressed. The pressing block 37 continuously slides towards the inner side of the operation groove. After contacting the reset block 41, the two first slopes 43 cooperate to force it to move and drive the limiting plate 40 to squeeze the second spring 42. When the pressing block 37 contacts the pressing plate 44, the first slope 43 squeezes the second slope 45, forcing its connecting rod to drive the return torsion spring 46 to retract, so that the pressing plate 44 retracts into the inner side of the pressing groove. Until the elastic pressing groove is close to the pressing groove, the return torsion spring 46 is no longer blocked and drives the pressing plate 44 to spring into the inner side of the elastic pressing groove. At this time, the brush plate 9 and the sponge brush 57 are released. The first rubber pad 38 rebounds, and the pressing block 37 moves back to make one end of the pressing plate 44 abut against the inner wall of the elastic pressing groove, completing the locking.

[0026] Furthermore, in this embodiment, the opposite ends of the pressing block 37 and the reset block 41 are both provided with mutually fitting first slopes 43. An extrusion groove is formed in the reset block 41 at the position of its first slope 43. A connecting rod is rotatably connected inside the extrusion groove. An extrusion plate 44 is sleeved on the outer side of the connecting rod. A second slope 45 that fits the first slope 43 is formed on one side of the extrusion plate 44. A return torsion spring 46 is installed between the connecting rod and the inner wall of the extrusion groove. An elastic pressing groove is formed in the pressing block 37 at the position of its first slope 43. A pressing rod 47 is installed on one side of the limiting plate 40. A dragging groove is formed in the placing seat on one side of the operation groove. The pressing rod 47 is slidably connected to the dragging groove. A rotating plate 48 is installed at one end of the pressing rod 47 extending outside the dragging groove. Pressing the rotating plate 48 can drive the pressing rod 47 and the limiting plate 40 to move, squeezing the second spring 42, making the reset block 41 move away from the pressing block 37, and the pressing plate 44 is dragged out of the inner side of the elastic pressing groove. At this time, the first rubber pad 38 rebounds completely, and the elastic pressing groove on the pressing block 37 is misaligned with the extrusion groove. At this time, releasing the rotating plate 48 will not re-lock either. Then the sponge brush 57 can be removed for maintenance.

[0027] Furthermore, in this embodiment, both ends of the base 1 are threadedly connected with side plates through bolts. An insertion cylinder 49 is embedded inside the side plates. The top end of the insertion cylinder 49 is rotatably connected with a third threaded rod 50. A movable seat 51 is threadedly connected to the outside of the third threaded rod 50. Slopes are provided on both sides of the movable seat 51. First moving grooves are provided at the slope positions on both sides of the movable seat 51. A second moving groove is provided inside the movable seat 51 on one side of the first moving groove. The width of the second moving groove is greater than that of the first moving groove. A second moving block 52 is slidably connected inside the second moving groove. A first moving block 53 is fixedly connected to one side of the second moving block 52. The first moving block 53 is slidably connected to the first moving groove. The other end of the first moving block 53 is provided with an extension rod 54. Extension holes for the extension rod 54 to slide through are provided at both ends of the insertion cylinder 49. A linkage groove is provided on one side of the top end of the movable seat 51. A linkage block 55 slidably connected to the linkage groove is installed at the top end inside the insertion cylinder 49. The cross-section of the linkage block 55 is T-shaped. A knob 56 is installed at the top end of the third threaded rod 50. After inserting the insertion cylinders 49 into the soil at various places, turn the knob 56 at the top end of the first threaded rod 7, so that the movable seat 51 on the outside of the first threaded rod 7 moves downward in cooperation with the linkage groove and the linkage block 55. The first moving block 53 and the second moving block 52 also move inside the first moving groove and the second moving groove accordingly. Since the width of the second moving groove is greater than that of the first moving groove, the first moving block 53 and the second moving block 52 will not break away from the movable seat 51 when moving inside the first moving groove and the second moving groove. At this time, the extension rods 54 on both sides also extend outward and insert into the soil when the first moving block 53 and the second moving block 52 move, increasing the grip of the device. When encountering strong wind weather or being pulled or collided, it is not easy to shift or tip over.

[0028] When using a large-scale industrial photovoltaic power generation device that automatically follows the sun with this solution, the locking buckle can be unlocked to remove the sealing cover. Water can be poured into the inner side of the storage tank 4 through the water inlet pipe 5. When a cleaning operation is required, the water pump 11 can be started to cooperate with the water suction pipe 12 and the corrugated pipe 13 to transport the water source to the inner side of the flow groove. The water drips through the nozzle 14 and is adsorbed by the sponge brush 57, soaking it. The driving end of the first motor 10 is rotated forward and backward to drive the first threaded rod 7 to rotate, and cooperate with the adjusting plate 8 and the adjusting groove to drive the sponge brush 57 on the brush plate 9 to reciprocate and brush on the surface of the solar panel 3 to achieve the cleaning operation. The third motor 22 can be started to drive the second threaded rod 19 to rotate, so that the movable sleeve 30 moves inside the movable groove 18, and at the same time drives the positioning cylinder 20 to move. The movable column 21 inside the positioning cylinder 20 will gradually slide out as the inclination angle of the solar panel 3 increases, and the deflecting rod 2 inside the connecting seat 24 will also rotate to cooperate with the solar panel 3 to adjust the inclination angle. Then, the second motor 15 can be started to cooperate with the sliding block 23 and the sliding groove to drive the mounting plate 16 to rotate and move, so as to change the orientation of the solar panel 3, so that the solar panel 3 always corresponds to the irradiation angle and direction of the sun, receives more sunlight, and improves the photoelectric conversion efficiency. Hold the handle 33 at one end of the movable sleeve 30 to drive it to move. While the movable sleeve 30 is moving, it drives the reset plate 28 to compress the two groups of first springs 29 to retract, so that the positioning column 31 disengages from the inside of the positioning hole. Then, cooperate with the limiting groove, the limiting block 32 and the damping rotating shaft 25 to drive the positioning column 31 to rotate. After rotating to the specified angle, the handle 33 can be loosened backward. The two groups of first springs 29 are instantly reset, so that the positioning column 31 enters the positioning hole at the corresponding position, and the first magnetic member 34 and the second magnetic member 35 are adsorbed to strengthen the positioning effect, and the rotated and adjusted angle is positioned, so as to achieve the flipping effect and facilitate the disassembly, installation, taking and placing of the sponge brush 57. Fit the first rubber pad 38 to one side of the splicing plate 36, so that the pressing block 37 slides into the pressing groove, squeezing the brush plate 9 and the sponge brush 57, so that the first rubber pad 38 is compressed. The pressing block 37 continuously slides into the operation groove and contacts the reset block 41. Then, cooperate with the two groups of first slopes 43 to force it to move and drive the limiting plate 40 to squeeze the second spring 42. When the pressing block 37 contacts the pressing plate 44, the first slope 43 squeezes the second slope 45, forcing its connecting rod to drive the return torsion spring 46 to retract, so that the pressing plate 44 retracts into the pressing groove. Until the elastic pressing groove is close to the pressing groove, the return torsion spring 46 is no longer blocked and drives the pressing plate 44 to pop into the elastic pressing groove. At this time, the brush plate 9 and the sponge brush 57 are released, the first rubber pad 38 rebounds, and one end of the pressing block 37 that moves back and presses the pressing plate 44 abuts against the inner wall of the elastic pressing groove to complete the locking. Pressing the rotating plate 48 can drive the pressing rod 47 and the limiting plate 40 to move, squeezing the second spring 42, so that the reset block 41 moves away from the pressing block 37, and the pressing plate 44 is pulled out of the elastic pressing groove. At this time, the first rubber pad 38 rebounds completely, and the elastic pressing groove on the pressing block 37 is misaligned with the pressing groove. At this time, releasing the rotating plate 48 will not re-lock either.Then the sponge brush 57 can be removed for maintenance. After inserting the plug-in tubes 49 into the soil, twist the knob 56 at the top of the first threaded rod 7, so that the movable seat 51 outside the first threaded rod 7 moves downward in coordination with the linkage groove and the linkage block 55, and the first movable block 53 and the second movable block 52 also move inside the first movable groove and the second movable groove. Because the width of the second movable groove is greater than the width of the first movable groove, the first movable block 53 and the second movable block 52 will not be separated from the movable seat 51 when they move inside the first movable groove and the second movable groove. At this time, the extension rods 54 on both sides also extend outward and insert into the soil when the first movable block 53 and the second movable block 52 move, which increases the grip of the device and prevents it from shifting and tipping over in windy weather or when it is pulled and collided.
