[0033] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.

[0034] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0035] Please refer to Figure 1-12As shown in the figure, the present invention is a photovoltaic energy storage type new energy vehicle charging pile, including a charging pile 2, a base 1, a photovoltaic panel 5 and a main frame 7. A plurality of telescopic rods 4 and a hydraulic cylinder 17 are fixedly installed at the upper end of the base 1. A connecting rod one 23 is rotatably connected to the piston rod 21 of the hydraulic cylinder 17. The main frame 7 is fixedly connected to the other end of the connecting rod one 23. The plurality of telescopic rods 4 are also movably connected to the main frame 7 through the connecting rod one 23. A plurality of connecting rods two 33 are rotatably installed on the base 1. The other end of the connecting rod two 33 is movably connected to the main frame 7. The setting of the hydraulic cylinder 17 can drive the photovoltaic panel 5 to rotate a certain angle, so that the photovoltaic panel 5 can better receive sunlight from morning to night, improving the power generation efficiency of the photovoltaic panel 5. A plurality of sub-frames 6 are installed inside the main frame 7. The photovoltaic panel 5 is installed inside the corresponding sub-frame 6. A liquid cooling plate 15 arranged in an "S" shape is provided between the photovoltaic panel 5 and the sub-frame 6. The liquid cooling plate 15 is closely attached to the back plate of the photovoltaic panel 5. Cooling liquid will flow into the liquid cooling plate 15, thereby dissipating heat from the photovoltaic panel 5 through the liquid cooling plate 15, preventing the temperature of the photovoltaic panel 5 from being too high and resulting in a reduction in power generation efficiency. The liquid cooling plate 15 arranged in an "S" shape can maximize the contact area with the photovoltaic panel 5, improving the heat dissipation effect of the photovoltaic panel 5, and thus improving the power generation efficiency of the photovoltaic panel 5.

[0036] Upper branch pipes 14 and lower branch pipes 16 are respectively provided at both ends of each liquid cooling plate 15. A plurality of upper branch pipes 14 are jointly connected to an upper manifold 8. A plurality of lower branch pipes 16 are jointly connected to a lower manifold 13. A transition box 18 and a cooling box 32 are fixedly connected to one of the bases 1. A water inlet pipe 19 is connected between the upper manifold 8 and the transition box 18. A water outlet pipe 12 is connected between the lower manifold 13 and the cooling box 32. And the height of the transition box 18 is greater than the height of the cooling box 32. Each photovoltaic panel 5 is provided with an independent liquid cooling plate 15, an independent upper branch pipe 14 and a lower branch pipe 16. If a failure occurs in the liquid cooling system of a single photovoltaic panel 5, it will not affect the heat dissipation of other photovoltaic panels 5. The cooling liquid in each liquid cooling plate 15 flows into the corresponding lower branch pipe 16 from the lower manifold 13. After the cooling liquid enters the liquid cooling plate 15, it absorbs the heat of the photovoltaic panel 5 and then flows out from the upper branch pipe 14, converging into the upper manifold 8. Through the flowing cooling liquid, it can ensure that the liquid cooling plate 15 can always effectively absorb the heat of the photovoltaic panel 5, significantly reducing the temperature of the photovoltaic panel 5 and improving the power generation efficiency of the photovoltaic panel 5.

[0037] A connecting plate 22 is sleeved on the piston rod 21 of the hydraulic cylinder 17. The other end of the connecting plate 22 is fixedly connected with a first rack 25. A support plate 52 is also fixedly connected to the base 1. A first gear 26 is rotatably installed on the support plate 52. The first rack 25 is meshed with the first gear 26. The other side of the first gear 26 is meshed with a second rack 28. A guide groove 53 is provided on the side wall of the second rack 28. A guide rod 27 is fixedly connected to the support plate 52. The guide rod 27 is slidably connected with the guide groove 53. A push plate 36 is slidably connected inside the cooling box 32. The bottom end of the second rack 28 abuts against the push plate 36. During the sun's operation from morning to evening in a day, the tilt angle of the photovoltaic panel 5 needs to be adjusted from a smaller tilt angle to a larger tilt angle first, and then adjusted back from the larger tilt angle to the smaller tilt angle to effectively receive sunlight. When the hydraulic cylinder 17 drives the piston rod 21 to move and the tilt angle of the photovoltaic panel 5 becomes larger, at this time, the piston rod 21 needs to move upward. The moving piston rod 21 can drive the first rack 25 to move upward through the connecting plate 22. The first rack 25 drives the first gear 26 to rotate. When the first gear 26 rotates, it drives the second rack 28 to move downward. The second rack 28 will drive the push plate 36 to move downward. The push plate 36 makes the coolant in the cooling box 32 enter the inside of the liquid cooling plate 15 through the water outlet pipe 12, the lower collecting pipe 13, and the lower branch pipe 16, thereby cooling the liquid cooling plate 15. There is no need to additionally set a pump body to realize the input of the coolant, nor to additionally use the electric energy of the photovoltaic panel 5, which is more energy-saving. After the coolant absorbs heat, it enters the transition box 18 through the upper branch pipe 14, the upper collecting pipe 8, and the water inlet pipe 19 for storage. At this time, the transition box 18 is not connected to the cooling box 32, avoiding the coolant with a higher temperature in the transition box 18 from entering the cooling box 32 and causing the temperature of the coolant in the cooling box 32 to rise, thereby reducing the cooling effect on the photovoltaic panel 5. The coolant in the transition box 18 is naturally cooled at night and then flows back into the cooling box 32.

[0038] Support rods 30 are fixedly connected to the inner wall of the cooling box 32. A plurality of first springs 31 are connected between the support rods 30 and the push plate 36. Two shape memory alloy sheets 29 are also connected to the bottom side wall of the second rack 28. The shape memory alloy sheets 29 also abut against the push plate 36. Due to the arrangement of the two shape memory alloy sheets 29, from morning to noon, as the external temperature gradually rises, the temperature of the photovoltaic panel 5 will also gradually increase. Therefore, it is necessary to increase the supply amount of the coolant. When the external temperature gradually rises to a certain threshold, the two shape memory alloy sheets 29 will deform and bend downward. Thus, at a higher temperature at noon, on the basis of the second rack 28 pushing the push plate 36, the downward moving distance of the push plate 36 can be increased, thereby increasing the supply amount of the coolant and improving the heat dissipation effect of the photovoltaic panel at noon. When it is from noon to evening, the external temperature gradually decreases, and the two shape memory alloy sheets 29 will gradually return to their original state.

[0039] A moving groove 54 is formed in the first rack 25. A connecting cross bar 55 is slidably connected inside the moving groove 54. Connecting blocks 24 are fixedly connected to both ends of the cross bar 55. A vertical portion is provided on the connecting block 24. The bottom end of the vertical portion abuts against the push plate 36. And a pressing portion 64 is provided at the middle position of the cross bar 55. An installation groove 65 is further provided on the side wall of the first rack 25. A stop frame 63 is slidably connected inside the installation groove 65. An extrusion portion 62 is fixedly connected to one end of the stop frame 63. A third spring 60 is fixedly connected between the other end of the stop frame 63 and the inner wall of the installation groove 65. An upper abutting portion 58 is provided at the end of the stop frame 63 located outside the installation groove 65. Two external connection blocks 59 are fixedly connected to the outer wall of the first rack 25. External connection rods 61 are fixedly connected to both of the two external connection blocks 59. The stop frame 63 is slidably connected to the external connection rod 61. A lower abutting block 56 is fixedly connected to the base 1. A lower abutting portion 57 is provided on the lower abutting block 56.

[0040] From morning to noon, driven by the piston rod 21, the first rack 25 moves upward. At this time, the second rack 28 can move downward to squeeze the push plate 36 to realize the supply of the coolant. At the same time, under the action of gravity, the connecting block 24 and the cross bar 55 will move downward along the moving groove 54, keeping the bottom end of the vertical portion of the connecting block 24 always in contact with the push plate 36. When the first rack 25 moves upward to the uppermost position, when the connecting block 24 and the cross bar 55 move downward under the action of gravity, the pressing portion 64 will squeeze the extrusion portion 62 to move in a direction away from each other and compress the third spring 60. The cross bar 55 will move to below the extrusion portion 62. Then, the extrusion portion 62 will reset under the action of the third spring 60.

[0041] From noon to evening, driven by the piston rod 21, the first rack 25 moves downward. At this time, the second rack 28 moves upward and no longer pushes the push plate 36. And at this time, since the bottom end of the vertical portion of the connecting block 24 always abuts against the push plate 36 and the cross bar 55 is located below the extrusion portion 62, when the first rack 25 moves downward, the extrusion portion 62 will push the cross bar 55 to drive the vertical portion of the connecting block 24 to continue to push the push plate 36, continuously realizing the supply of the coolant. When the first rack 25 moves to the lowermost position, at this time, the upper abutting portion 58 on the stop frame 63 will contact and squeeze the lower abutting portion 57 on the lower abutting block 56, so that the stop frame 63 drives the extrusion portion 62 to retract into the installation groove 65 again and no longer blocks the cross bar 55. When the push plate 36 resets under the action of the first spring 31, it will also drive the connecting block 24 and the cross bar 55 to move upward in the moving groove 54, so as to reset.

[0042] A channel 34 is provided inside the push plate 36, a magnet 37 is fixed inside the channel 34, a through pipe 35 is provided on the transition box 18, a protrusion 39 is provided in the middle part of the through pipe 35, a fixing plate 40 is fixed on the inner wall of the through pipe 35, a spring 2 38 is fixed on one end of the fixing plate 40, a magnet 2 41 is slidably connected inside the through pipe 35, the diameter of the magnet 2 41 is the same as the inner diameter of the non-protrusion 39 of the through pipe 35, and the magnet 2 41 is fixed to the other end of the spring 2 38. When the photovoltaic panel 5 stops generating electricity, that is, when there is no sunlight, the push plate 36 is reset to its original position under the action of the spring 1 31, and the channel 34 inside the push plate 36 is The through-tube 35 corresponds to the magnet one 37 and the magnet two 41 at this time are in a state of mutual repulsion. The magnet one 37 pushes the magnet two 41 to move inside the protrusion 39 and compresses the spring two 38 at the same time. When the magnet two 41 is inside the protrusion 39, the entire through-tube 35 is no longer blocked, and the coolant in the transition box 18 that is naturally cooled at night can flow into the cooling box 32. When the push plate 36 moves downward to squeeze the coolant in the cooling box 32 into the liquid cooling plate 15, the channel 34 is staggered with the through-tube 35, and the magnet two 41 is reset under the action of the spring two 38 to continue to block the through-tube 35 to prevent the coolant with a higher temperature from entering the cooling box 32.

[0043] The main frame 7 is provided with a sliding frame 11, and a limiting wheel 44 is rotatably installed on the side wall of the sliding frame 11. A limiting groove 43 is provided on the side wall of the main frame 7, and the limiting wheel 44 is slidably connected to the limiting groove 43. A magnet rod 45 is slidably connected inside the sliding frame 11, and a cleaning block 20 is fixedly connected to the lower end of the magnet rod 45. The side of the main frame 7 is also fixedly connected to a track 9, and an arc groove is provided on the track 9. A moving wheel 51 is rotatably installed on the sliding frame 11, and the moving wheel An arc-shaped protrusion is provided on 51, and the moving wheel 51 is rotatably connected to the track 9. A magnetic rotation plate 46 is provided above the magnet rod 45, and rotating rods 47 are fixedly connected at both ends of the magnetic rotation plate 46. The rotating rod 47 is rotatably connected to the sliding frame 11, and one end of the rotating rod 47 passes through the sliding frame 11 and is fixedly connected to a gear 2 49. A rack 3 48 is fixedly installed on the track 9, and the rack 3 48 is meshed with the gear 2 49. The moving wheel 51 is also coaxially mounted with a clockwork box 50 and a fan blade 3.

[0044] When the photovoltaic panel 5 is tilted, under the gravity of parts such as the sliding frame 11, the moving wheel 51 rotates on the track 9, so that the sliding frame 11 can drive the cleaning block 20 to clean the surface of the photovoltaic panel 5, avoiding dust from affecting the sunlight received by the photovoltaic panel 5 and ensuring the power generation efficiency of the photovoltaic panel 5. At the same time, the magnetic rotation plate 46 and the magnet rod 45 attract each other at this time, reducing the pressure between the cleaning block 20 and the photovoltaic panel 5 and avoiding the situation where the gravity of parts such as the sliding frame 11 cannot drive the cleaning block 20 to move downward due to large friction to clean the surface of the photovoltaic panel 5. And because the third rack 48 is a one-way rack, when the sliding frame 11 moves downward, the third rack 48 cannot drive the second gear 49 to rotate. Therefore, the magnetic rotation plate 46 and the magnet rod 45 attract and remain in an attracting state. When the cleaning block 20 moves downward to a lower end position of the photovoltaic panel 5, when the sliding frame 11 moves downward, the third rack 48 at this end can drive the second gear 49 to rotate, so that the magnetic rotation plate 46 rotates to a state of repelling the magnet rod 45. At this time, the pressure between the cleaning block 20 and the photovoltaic panel 5 will increase. When the sliding frame 11 moves upward, it can improve the cleaning effect of the cleaning block 20 on the photovoltaic panel 5. And when the sliding frame 11 moves upward from the lower end position of the photovoltaic panel 5, the third rack 48 cannot drive the second gear 49 to rotate, and the magnetic rotation plate 46 will remain in a state of repelling the magnet rod 45 until the second gear 49 contacts the third rack 48 at the higher end position of the photovoltaic panel 5. At this time, the third rack 48 can drive the second gear 49 to rotate, making the magnetic rotation plate 46 rotate again to a state of attracting the magnet rod 45.

[0045] When the sliding frame 11 moves to the lower end position of the photovoltaic panel 5, a plurality of arc-shaped grooves on the track 9 at this end are provided with a third magnet, and a plurality of arc-shaped protrusions on the moving wheel 51 are provided with a fourth magnet. At this time, the fourth magnet on the moving wheel 51 and the third magnet on the track 9 adsorb each other to fix the moving wheel 51. When the wind blows outside, the fan blade 3 is blown by the airflow to rotate, tensioning the spring inside the spring box 50 to store energy for the spring. When the energy stored in the spring reaches a certain level, it can overcome the attraction between the fourth magnet on the moving wheel 51 and the third magnet on the track 9, causing the moving wheel 51 to rotate in the reverse direction, driving the sliding frame 11 to move towards the higher end position of the photovoltaic panel 5, realizing the secondary cleaning of the photovoltaic panel 5 by the cleaning block 20. The secondary cleaning of the photovoltaic panel 5 by the cleaning block 20 is realized by wind power drive, without additional power consumption. And through spring energy storage, it can ensure that the cleaning block 20 moves to the higher end position of the photovoltaic panel 5 at one time, avoiding the cleaning block 20 stopping on the photovoltaic panel 5 halfway and affecting the sunlight received by the photovoltaic panel 5. The setting of the arc-shaped groove and the arc-shaped protrusion prevents the moving wheel 51 from slipping when rotating, resulting in the cleaning block 20 being unable to move to the higher end position of the photovoltaic panel 5 driven by the moving wheel 51.

[0046] There are clamping blocks 10 between the auxiliary frames 6. The clamping blocks 10 are movably installed on the main frame 7 through bolts 42, and both ends of the clamping blocks 10 are in contact with the photovoltaic panel 5.

[0047] Working principle:

[0048] From morning to noon, the hydraulic cylinder 17 drives the angle of the photovoltaic panel 5 to gradually increase through the piston rod 21. At the same time, through the cooperation of the first rack 25, the first gear 26, the second rack 28 and the push plate 36, the coolant inside the cooling box 32 flows to the liquid cooling plate 15. The liquid cooling plate 15 absorbs the heat of the photovoltaic panel 5, causing the temperature of the coolant to rise. The coolant then flows back to the transition box 18 again. From noon to evening, the hydraulic cylinder 17 drives the angle of the photovoltaic panel 5 to gradually decrease through the piston rod 21. At this time, the vertical part of the connecting block 24 continues to push the push plate 36 downward to achieve continuous supply of the coolant and ensure the heat dissipation effect of the photovoltaic panel 5. When the photovoltaic panel 5 is tilted, under the action of the gravity of parts such as the sliding frame 11, the moving wheel 51 rotates on the track 9, so that the sliding frame 11 can drive the cleaning block 20 to clean the surface of the photovoltaic panel 5, avoiding dust from affecting the sunlight received by the photovoltaic panel 5 and ensuring the power generation efficiency of the photovoltaic panel 5. When the wind blows outside, the fan blade 3 is driven by the airflow to rotate, tension the spring inside the spring box 50, and store energy for the spring. When the energy stored in the spring reaches a certain level, it can overcome the attraction between the fourth magnet on the moving wheel 51 and the third magnet on the track 9, causing the moving wheel 51 to rotate in the reverse direction, driving the sliding frame 11 to move towards the higher end of the photovoltaic panel 5, realizing the secondary cleaning of the photovoltaic panel 5 by the cleaning block 20 and ensuring the power generation efficiency of the photovoltaic panel 5.
