[0030] 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.
[0031] Example 1, refer to Figure 1-11 A solar power generation device capable of enhancing sunlight exposure comprises a base 1, with protrusions 2 fixedly connected to both sides of the base 1, electric shafts 3 mounted on the protrusions 2 on both sides, connecting plates 4 fixedly connected to the outer wall of the electric shaft 3, a concentrating plate 5 fixedly connected between the connecting plates 4 on both sides, a drainage groove 8 provided inside the concentrating plate 5, a bracket 6 fixedly connected to the outer wall of the concentrating plate 5, a photovoltaic cell 7 mounted on the bracket 6, the photovoltaic cell 7 being located above the concentrating plate 5, a cleaning mechanism being provided on the concentrating plate 5, the cleaning mechanism comprising limit rails 12 arranged on both sides of the concentrating plate 5;
[0032] The interior of the limit rails 12 on both sides is rotatably connected with a reciprocating screw 10, and a belt 11 is sleeved between the ends of the two reciprocating screws 10. A drive motor 9 is fixedly connected to the outer wall of one of the two limit rails 12, and one end of the two reciprocating screws 10 is connected to the output end of the drive motor 9. A drainage groove 8 is provided inside the focusing plate 5, and a mounting plate 13 is commonly threaded on the two reciprocating screws 10. Vertical plates 19 are fixedly connected on both sides of the mounting plate 13, and rollers 21 are rotatably connected to the vertical plates 19 on both sides. The rollers 21 are in rolling contact with the outer wall of the limit rail 12.
[0033] A toothed disc 38 is rotatably connected to the roller 21, and a plurality of one-way baffles 40 are rotatably connected inside the roller 21. The outer sides of the plurality of one-way baffles 40 are fixedly connected with pressure springs 39, and one end of the pressure spring 39 away from the one-way baffle 40 is fixedly connected to the inner side wall of the roller 21. A cross bar 37 is fixedly connected to the outer side wall of the toothed disc 38, and one end of the cross bar 37 away from the roller 21 is fixedly connected to the disc 22. The disc 22 is rotatably connected with a swing arm 27. Both sides of the mounting plate 13 are fixedly connected to a spray gun 23, and the inside of the spray gun 23 is slidably connected with a pressure rod 25. A pressure spring 24 is sleeved on the outer side wall of the pressure rod 25, and a pressure block 26 is fixedly connected to the end of the pressure rod 25, and the end of the swing arm 27 away from the disc 22 is rotatably connected to the outer side wall of the pressure block 26.
[0034] The bottoms of the two spray barrels 23 are both connected with a spray pipe, and a nozzle 28 is connected between the two spray pipes. The nozzle 28 is provided with a plurality of spray holes 29.
[0035] A water storage box 44 and a liquid storage box 43 are fixedly connected to the outer wall of the mounting plate 13. The interiors of the two spray barrels 23 are connected to a liquid suction pipe 41. The end of the liquid suction pipe 41 away from the spray barrel 23 is connected to the interior of the liquid storage box 43. An arc-shaped member 30 is fixedly connected to the outer wall of the mounting plate 13, and a plurality of cleaning brushes 31 are provided on the arc-shaped member 30.
[0036] In this embodiment, through the setting of the concave arc-shaped focusing plate 5, when sunlight shines on the focusing plate 5, the focusing plate 5 will use the focusing characteristics of the curved optical element to concentrate the sunlight onto the photovoltaic cell 7, and the photovoltaic cell 7 will convert the solar energy into electrical energy (this is the existing technology and will not be elaborated in detail). During use, if dust, bird droppings and other impurities adhere to the surface of the focusing plate 5, affecting the focusing of the focusing plate 5, the operator can turn on the drive motor 9 to drive the reciprocating screw 10 connected to its output end to rotate. When one reciprocating screw 10 rotates, the belt 11 will cause the two reciprocating screws 10 to rotate synchronously. When the two reciprocating screws 10 rotate synchronously, the mounting plate 13 will move from right to left. During the movement of the mounting plate 13, the rollers 21 on both sides of the mounting plate 13 will contact the outer wall of the limit rail 12 and rotate counterclockwise during the movement. When the rollers 21 rotate counterclockwise, they will drive the one-way baffle 40 to move. The one-way baffle 40 rotates synchronously counterclockwise. When the one-way baffle 40 rotates counterclockwise, the one-way baffle 40 will press against the right-angled edge of the toothed disc 38, driving it to rotate together, thereby driving the disc 22 to rotate synchronously through the cross bar 37. When the disc 22 rotates, the swing arm 27 pulls the pressure block 26, so that the pressure rod 25 performs a reciprocating suction motion in the spray barrel 23. When the pressure rod 25 performs a reciprocating suction motion in the spray barrel 23, the cleaning liquid in the liquid storage box 43 is sucked into the liquid storage box 43 through the liquid pipe 41. The cleaning liquid is squeezed into the nozzle 28 through the spray pipe connected to the nozzle 23, and finally the cleaning liquid is dripped onto the surface of the focusing plate 5 through multiple spray holes 29. When the mounting plate 13 moves from right to left, it will also drive the arc-shaped member 30 to move synchronously. When the arc-shaped member 30 moves, the cleaning brush 31 at its bottom will scrape the surface of the focusing plate 5. In conjunction with the cleaning liquid dripping from the spray hole 29, the dust, bird droppings and other impurities on the surface of the focusing plate 5 can be cleaned.
[0037] Example 2, refer to Figure 1-11 The bottom of the water storage box 44 is connected to the connecting box 32, and both sides of the connecting box 32 are slidably connected with sliding pipes 34, and a flushing mechanism is provided on the sliding pipes 34.
[0038] The flushing mechanism includes a liquid inlet 36 provided on the sliding tube 34 . A return spring 35 is sleeved on the outer wall of the sliding tube 34 . The return spring 35 contacts the outer wall of the communication box 32 .
[0039] The ends of the two sliding tubes 34 away from the liquid inlet 36 are connected to a transverse tube 33 , and a plurality of drip holes 42 are formed on the transverse tube 33 .
[0040] A push rod 16 is fixedly connected to the outer wall of each sliding tube 34 , and a torsion spring shaft 45 is installed at the end of the push rod 16 , and an outward moving part 17 is provided on the torsion spring shaft 45 . A limiting part 18 is fixedly connected to the outer wall of the push rod 16 , and the limiting part 18 is in contact with the outward moving part 17 .
[0041] One end of the rotating rod 20 away from the roller 21 is fixedly connected to the rotating wheel 14 , and an outward moving rod 15 is fixedly connected to the outer side wall of the rotating wheel 14 , and a contact wheel is provided on the outward moving rod 15 .
[0042] When the roller 21 rotates clockwise, the rotating wheel 14 will rotate synchronously with the rotating rod 20, and the contact wheel 21 at the end of the outer moving rod 15 will be moved clockwise by the rotating wheel 14. When the push rod 16 drives the slide tube 34 to move in the direction away from the arc part 30, the liquid inlet hole 36 originally located outside the connecting box 32 will enter the connecting box 32. When the liquid inlet hole 36 enters the connecting box 32, the water in the water storage box 44 will enter the slide tube 34 through the liquid inlet hole 36, and then enter the cross tube 33 through the slide tube 34. When there is water in the cross tube 33, it will drip onto the surface of the focusing plate 5 through the multiple drip holes 42 opened on the cross tube 33, and rinse the surface of the focusing plate 5 with the detergent. By spraying the detergent first and then rinsing with clean water, the impurities on the surface of the focusing plate 5 can be quickly cleaned to prevent the detergent from remaining on the surface of the focusing plate 5 and affecting the focusing effect of the focusing plate 5.
[0043] It should be noted that when the rotating wheel 14 drives the outer moving rod 15 to rotate counterclockwise, the side of the outer moving rod 15 away from the contact wheel will contact the bottom edge of the outer moving member 17 and push the outer moving member 17 to flip upward until it no longer blocks the rotation path of the outer moving rod 15 (refer to Figure 11), when the outward moving member 17 is pushed to flip upward, since the contact wheel at the bottom of the outward moving rod 15 does not contact the oblique edge of the outward moving member 17, the push rod 16 will not be pushed. Referring to the above principle, when the push rod 16 is no longer pushed, the multiple drip holes 42 will not drip clean water onto the surface of the focusing plate 5. At the same time, due to the obstruction of the limit member 18, the outward moving member 17 can only flip downward and cannot flip upward.
[0044] It should be noted that one-way valves are provided inside the liquid suction pipe 41 and the spray pipe to ensure that the spray pipe only sprays liquid and the liquid suction pipe 41 only absorbs liquid.
[0045] It should be noted that both the liquid storage box 43 and the water storage box 44 are provided with liquid adding ports, through which water pipes can be connected to the outside.
[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
