Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a distributed photovoltaic power generation device combined with a highway. Background Art

[0002] A distributed photovoltaic power generation device is a device that uses solar photovoltaic technology to generate electricity. It can be installed in a distributed manner on the roof, ground or other open space of a building to achieve local electricity supply. This device usually consists of photovoltaic panels, inverters, brackets, cables and monitoring systems.

[0003] The distributed photovoltaic power generation devices in the existing technology do not have a structure that is integrated with the road. In addition, when vehicles continue to travel on the road, the air flow sometimes causes the device to shake, posing a safety hazard. The device is in a relatively harsh environment for a long time, which will affect its service life. When snow accumulates on the top of the device, it will affect the strength of the device.

[0004] In the prior art, a Chinese patent for a distributed photovoltaic power generation device combined with a highway (publication number CN116827222B) has been proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a distributed photovoltaic power generation device that can be used across the highway to meet the photovoltaic power generation needs in the area along the highway. By setting up a movable panel, after the distributed photovoltaic power generation device is fixed, when the movement of vehicles generates strong airflow or encounters strong winds, the present invention can improve the structural stability of the distributed photovoltaic power generation device, thereby buffering the impact of the distributed photovoltaic power generation device in bad weather and preventing the distributed photovoltaic power generation device from being damaged. However, in actual use, due to the large number of vehicles on the highway, the ground will be shaken by the passing vehicles. Installing solar photovoltaic panels on the highway will cause certain damage to the solar photovoltaic panels due to the ground vibration, thereby affecting the service life of the solar photovoltaic panels. In addition, there is a lot of dust on the highway, and the dust raised by the passing vehicles will adhere to the solar photovoltaic panels, thereby affecting the photovoltaic panels' conversion effect on sunlight, which is not conducive to practical application. Summary of the Invention

[0005] The purpose of the present utility model is to provide a distributed photovoltaic power generation device combined with a highway to solve the problems raised in the above background technology.

[0016] By adopting the above technical solution, during the reciprocating sliding of the sleeve column relative to the support column, the second fixed plate moves relative to the second lifting plate, so that the rack and the gear are driven to move relative to each other through the sliding rod. The engagement of the two causes the gear to rotate reciprocatingly, and the reciprocating screw is driven in one direction through the one-way bearing.

[0017] A further improvement of the technical solution of the present utility model is that a filter screen is provided inside the connecting pipe at one end close to the transfer cylinder.

[0018] The above technical solution is adopted to prevent dust in the transfer cylinder from entering the piston cavity when negative pressure is generated inside the piston cavity.

[0019] A further improvement of the technical solution of the present invention is that: the bottom ends of the support columns are fixedly connected to positioning plates, and a plurality of positioning holes are opened on the outer sides of the positioning plates.

[0020] The above technical solution makes it easy to fix the support columns to the ground on both sides of the highway.

[0021] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0033] The present invention is further described in detail below with reference to the embodiments:

[0034] Example 1

The top of the first fixed plate 6 is slidably connected to the guide rod 7. The top of the guide rod 7 is fixedly connected to the bottom of the first lifting plate 5. The bottom of the guide rod 7 extends to the bottom of the first fixed plate 6 and is fixedly connected to the pad 8. The outside of the guide rod 7 and both sides of the first fixed plate 6 are covered with springs 9. A movable frame 22 is fixedly connected between the adjacent sides of every two sleeve columns 2. A dust reduction component is provided at the bottom of the movable frame 22. The dust reduction component is used to use vibration to generate air pressure to clean dust.

[0036] In this embodiment, a sleeve column 2 is provided that is movable relative to the support column 1, so that the two can only slide relative to each other in the vertical direction under the limitation of the piston plate 17, the slide rod 12 and the guide rod 7. The vibration is buffered by the springs 9 on both sides, thereby reducing the damage of the vibration to the solar photovoltaic panel 4, greatly improving the service life of the solar photovoltaic panel, and being beneficial to practical applications.

[0037] Example 2

[0038] like Figure 3 and Figure 6 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the dust reduction component includes a transfer cylinder 18 fixedly connected to the bottom of the movable frame 22, and two connecting pipes 19 are symmetrically arranged on the outside of the transfer cylinder 18. The end of the connecting pipe 19 away from the connecting pipe 19 is fixedly connected to the sleeve 2, and the interior of the transfer cylinder 18 is communicated with the interior of the piston chamber 16 through the connecting pipe 19. A dust exhaust pipe 21 is provided at the bottom of the transfer cylinder 18, and a dust extraction pipe 20 is provided on one side of the transfer cylinder 18. Both the dust extraction pipe 20 and the dust exhaust pipe 21 are provided with a one-way valve.

[0039] In this embodiment, the piston plate 17 slides relative to the piston chamber 16 (i.e., it performs piston motion in the piston chamber 16). When the piston plate 17 moves upward relative to the piston chamber 16, the internal space of the piston chamber 16 decreases, generating positive pressure and discharging it into the transfer cylinder 18, so that positive pressure is generated in the transfer cylinder 18. At this time, the one-way valve located in the dust extraction pipe 20 is blocked, and the one-way valve located in the dust extraction pipe 21 is connected, so that the gas in the transfer cylinder 18 is discharged outward through the dust exhaust pipe 21 (when there is dust in the transfer cylinder 18, the dust is discharged from the dust exhaust pipe 21); when the piston plate 17 moves downward relative to the piston chamber 16, the internal space of the piston chamber 16 increases, generating negative pressure, and at the same time generating negative pressure in the transfer cylinder 18. At this time, the one-way valve located in the dust extraction pipe 20 is connected, and the one-way valve located in the dust extraction pipe 21 is blocked, so that the transfer cylinder 18 can extract dust from the solar photovoltaic panel 4 through the dust extraction pipe 20, the dust inlet pipe 27 and the dust suction port 31.

[0040] Example 3

[0041] like Figure 3 and Figure 6As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a through groove is opened on the top of the movable frame 22 and extends to the bottom, and a reciprocating screw rod 23 is rotatably connected between the inner walls of the movable frame 22, and the outer side of the reciprocating screw rod 23 is threadedly connected to the sliding frame 24, and the outer side of the sliding frame 24 is slidably connected to the inner wall of the movable frame 22, and a sliding groove 29 is opened on one side of the sliding frame 24 and extends to the other side, and a dust inlet pipe 27 is slidably connected between the inner walls of the two sliding grooves 29, and the outer side of the dust inlet pipe 27 and the side away from the two sliding frames 24 are symmetrically fixed with a limiting ring 28, and the outer side of the limiting ring 28 is slidably connected to one side of the sliding frame 24, and the two dust extraction pipes 20 are away from the transfer cylinder 18. One end is connected to the two ends of the dust inlet pipe 27 through a hose, and a plurality of dust suction ports 31 are provided on the outer side of the dust inlet pipe 27, and the outer side of the dust extraction pipe 20 and the inside of the sliding groove 29 are set to a square structure.

[0042] In this embodiment, by rotating the reciprocating screw 23, the sliding frame 24 is driven to slide along the inner wall of the movable frame 22, thereby driving the dust inlet pipe 27 to move in the horizontal direction. The dust inlet pipe 27 is limited by the limiting rings 28 on both sides and the square structure of the contact area between the dust inlet pipe 27 and the slide groove 29, so that the dust inlet pipe 27 can only slide relative to the slide groove 29.

[0043] like Figure 2 and Figure 3 As shown, preferably, the tops of the two mounting beams 3 are symmetrically fixedly connected with mounting columns 25, the mounting columns 25 located at the tops of different mounting beams 3 have different heights, and a guide frame 26 is fixedly connected between the adjacent sides of the mounting beams 3. A guide groove 30 is provided on one side of the guide frame 26 and passes through to the other side, and the outer side of the dust inlet pipe 27 is slidably connected to the inner wall of the guide groove 30.

[0044] In this embodiment, when the sliding frame 24 slides along the inner wall of the movable frame 22, it will drive the dust inlet pipe 27 to move in the horizontal direction, and under the guidance of the guide frame 26, the dust inlet pipe 27 will move along the guide groove 30, so that the dust suction port 31 will move along the surface of the solar photovoltaic panel 4 along with the dust inlet pipe 27.

[0045] Example 4

[0046] like Figure 2 and Figure 7As shown, on the basis of Example 3, the utility model provides a technical solution: preferably, one side of the mounting beam 3 is symmetrically rotatably connected to two one-way bearings 13, one side of the one-way bearing 13 is fixedly connected to a gear 14, the side of the center axis of the one-way bearing 13 away from the gear 14 extends to the inside of the movable frame 22 and is fixedly connected to one end of the reciprocating screw 23, the side of the sleeve column 2 away from the first lifting plate 5 is fixedly connected to the second lifting plate 11, the side of the support column 1 away from the first fixed plate 6 is fixedly connected to the second fixed plate 10, the top of the second lifting plate 11 is slidably connected to the slide rod 12, the top of the slide rod 12 is fixedly connected to the rack 15, the rack 15 is meshed with the gear 14, and the bottom of the slide rod 12 extends to the bottom of the second lifting plate 11 and is fixedly connected to the top of the second fixed plate 10.

[0047] In this embodiment, during the reciprocating sliding of the sleeve column 2 relative to the support column 1, the second fixed plate 10 moves relative to the second lifting plate 11, so that the rack 15 and the gear 14 are driven to move relative to each other through the sliding rod 12. The engagement of the two causes the gear 14 to rotate back and forth, and the reciprocating screw 23 is driven in one direction through the one-way bearing 13.

[0048] like Figure 4 Preferably, a filter screen 32 is provided inside the connecting pipe 19 at one end close to the transfer cylinder 18 .

[0049] In this embodiment, dust in the transfer cylinder 18 is prevented from entering the piston chamber 16 when negative pressure is generated inside the piston chamber 16 .

[0050] like Figure 1 and Figure 2 As shown, preferably, the bottom ends of the support columns 1 are fixedly connected to positioning plates, and a plurality of positioning holes are provided on the outer sides of the positioning plates.

[0051] In this embodiment, it is convenient to fix the support column 1 to the ground on both sides of the road.

[0052] The following is a detailed description of the working principle of the distributed photovoltaic power generation device combined with the highway.

[0053] like Figure 1-7 As shown, during use, when a vehicle passes or a strong wind blows, since the support column 1 and the sleeve column 2 are not relatively fixedly connected, the sleeve column 2 will move relative to the support column 1. The two can only slide relative to each other in the vertical direction under the limitation of the piston plate 17, the slide rod 12 and the guide rod 7. The vibration is buffered by the springs 9 on both sides, thereby reducing the damage of the vibration to the solar photovoltaic panel 4.

[0054] During the process, the piston plate 17 slides relative to the piston chamber 16 (that is, it performs piston movement in the piston chamber 16). When the piston plate 17 moves upward relatively, the internal space of the piston chamber 16 decreases, generating positive pressure and discharging it into the transfer cylinder 18, so that positive pressure is generated in the transfer cylinder 18. At this time, the one-way valve located in the dust extraction pipe 20 is blocked, and the one-way valve located in the dust extraction pipe 21 is opened, thereby allowing the gas in the transfer cylinder 18 to be discharged outward through the dust exhaust pipe 21 (when there is dust in the transfer cylinder 18, the dust is discharged from the dust exhaust pipe 21); when the piston plate 17 moves downward relatively, the internal space of the piston chamber 16 increases, generating negative pressure, and at the same time generating negative pressure in the transfer cylinder 18. At this time, the one-way valve located in the dust extraction pipe 20 is opened, and the one-way valve located in the dust extraction pipe 21 is blocked, thereby allowing the transfer cylinder 18 to extract dust from the solar photovoltaic panel 4 through the dust extraction pipe 20, the dust inlet pipe 27 and the dust suction port 31;

[0055] During the reciprocating sliding of the sleeve column 2 relative to the support column 1, the second fixed plate 10 moves relative to the second lifting plate 11, so that the rack 15 and the gear 14 are driven to move relative to each other through the sliding rod 12. The engagement of the two will cause the gear 14 to rotate back and forth, and the reciprocating screw rod 23 is driven by the one-way bearing 13 to rotate unidirectionally, thereby driving the sliding frame 24 to slide along the inner wall of the movable frame 22, thereby driving the dust inlet pipe 27 to move in the horizontal direction, and under the guidance of the guide frame 26, the dust inlet pipe 27 is moved along the guide groove 30, thereby causing the dust suction port 31 to move along the surface of the solar photovoltaic panel 4 along with the dust inlet pipe 27, thereby realizing comprehensive dust extraction of the solar photovoltaic panel 4.

[0056] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
