Description

Technical Field

[0001] This invention relates to the field of solar photovoltaic power generation technology, and in particular to a photovoltaic system cleaning device. Background Technology

[0002] Solar energy is the energy produced by the continuous nuclear fusion reactions inside or on the surface of the sun, particularly in sunspots. Solar energy boasts advantages such as abundant resources, long lifespan, wide distribution, safety, cleanliness, and reliable technology. Because it can be converted into various other forms of energy, its applications are extremely broad. Obtaining electricity from solar energy requires photovoltaic conversion using solar cells.

[0003] Photovoltaic systems require regular cleaning to remove dust and dirt from their surfaces to avoid affecting their power output. Currently, most methods involve spraying water onto the photovoltaic system first, followed by cleaning with a dedicated cleaning device. However, integrating the water spraying mechanism and the cleaning device into a single unit complicates the overall structure of the cleaning system and increases costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a photovoltaic system cleaning device with simple structure and reduced cost.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: Compared with the prior art, the advantages of the present invention are as follows: A photovoltaic system cleaning device is disclosed. The photovoltaic system includes photovoltaic panel units and a support frame. The photovoltaic panel units are supported on the support frame. The cleaning device includes a cleaning vehicle, a track, a drive mechanism, a parking platform, and a water spraying mechanism. The cleaning vehicle is slidably mounted on the photovoltaic panel units. The track is located on the side of the photovoltaic panel units. The parking platform is installed at the end of the photovoltaic system. The drive mechanism is located on a parking platform and connected to the cleaning vehicle to drive the cleaning vehicle to move. The water spraying mechanism is slidably mounted on the track and moves along the track to spray water to clean the photovoltaic system.

[0006] As a further improvement to the above technical solution: The track is mounted on a bracket on the side of the photovoltaic panel unit.

[0007] The water spraying mechanism includes multiple water spraying components, each of which is slidably mounted on a track at intervals and moves along the track to perform segmented water spraying cleaning on the photovoltaic system.

[0008] The water spray assembly includes a nozzle, a water pipe, and a power supply. The nozzle is slidably mounted on a track, and the water pipe is connected to the nozzle and connected to an external water source. The nozzle moves along the track.

When the nozzle collides with the impact rod, it pushes the impact rod to move horizontally, forcing the rotating shaft to rotate. This causes one end of the connecting rod to engage with the clamping seat on the nozzle, and the other end of the connecting rod to disengage from the clamping seat on the adjacent nozzle.

[0016] The nozzle is provided with an impact part, and the clamping seat is provided with a plug-in part. When the plug-in rod is plugged into the plug-in part, it forces the movable rod to drive the second clamping block to move downward to release the clamping connection with the wire rope.

[0024] As a further improvement to the above technical solution: The water spraying mechanism includes multiple nozzles and water pipes. Each nozzle is fixedly mounted at intervals on a bracket on the side of the photovoltaic system, and the water pipes are connected in series with each nozzle and connected to an external water source.

[0025] The cleaning vehicle and each nozzle are equipped with sensing components. When the cleaning vehicle moves close to the nozzle, it transmits a signal to cause the next nozzle to spray water.

[0026] An on / off valve is installed between the nozzle and the water pipe to control the water output.

[0027] The water spraying mechanism includes at least one rotating nozzle and a water pipe. The water pipe is connected to the rotating nozzle and to an external water source.

[0050] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] Example 1: like Figure 1 and Figure 2As shown, in a first embodiment of the photovoltaic system cleaning device of the present invention, the photovoltaic system includes a photovoltaic panel unit 1 and a support 2. The photovoltaic panel unit 1 is supported on the support 2. The cleaning device includes a cleaning vehicle 3, a track 4, a drive mechanism 5, a parking platform 6, and a water spraying mechanism 7. The cleaning vehicle 3 is slidably mounted on the photovoltaic panel unit 1. The track 4 is set on the support 2 on the side of the photovoltaic panel unit 1. The parking platform 6 is installed at the end of the photovoltaic system. The drive mechanism 5 is set on a parking platform 6 and connected to the cleaning vehicle 3 to drive the cleaning vehicle 3 to move. The water spraying mechanism 7 is slidably mounted on the track 4 and moves along the track 4 to spray water to clean the photovoltaic system. The present invention separates the movement of the cleaning vehicle 3 and the movement of the water spraying mechanism 7 by setting the track 4 to slide the water spraying mechanism 7, avoiding interference between the cleaning and water spraying actions. The water spraying mechanism 7 is not directly mounted on the cleaning vehicle 3, reducing the load on the cleaning vehicle 3, simplifying the structure, and reducing costs.

[0052] In this embodiment, the water spraying mechanism 7 includes multiple water spraying components 71, each of which is slidably mounted on the track 4 at intervals and moves along the track 4 to perform segmented water spraying cleaning of the photovoltaic system. In this structure, the use of multiple water spraying components 71 enables comprehensive and uniform water spraying of the photovoltaic system, and segmented cleaning can save water and adjust the water spraying strategy according to the degree of dirt in different areas.

[0053] In this embodiment, the water spray assembly 71 includes a nozzle 711, a water pipe 712, and a power supply 713. The nozzle 711 is slidably mounted on a track 4. The water pipe 712 is connected to the nozzle 711 and connected to an external water source. The nozzle 711 is powered by the power supply 713 to move along the track 4. A first sensor 714 is provided at the end of the track 4 and on the nozzle 711 to trigger the movement of the nozzle 711 by transmitting signals through touch. An on / off valve 715 is provided between the nozzle 711 and the water pipe 712 to control the water output. In this structure, the use of electronic control and sensors can achieve precise automated control, improving cleaning efficiency and effectiveness.

[0054] In this embodiment, the drive mechanism 5 includes a drive motor 51, a drive wheel 52, and a traction steel wire rope 53. The drive motor 51 is fixedly mounted on the parking platform 6, the drive wheel 52 is connected to the output end of the drive motor 51, and the traction steel wire rope 53 is wound around the drive wheel 52 and connected to the cleaning vehicle 3. Its structure is simple and reliable.

[0055] In this embodiment, the cleaning vehicle 3 is equipped with rollers 31 that slide on the guide rail. The cleaning vehicle 3 slides on the photovoltaic frame via the rollers 31, resulting in a low coefficient of friction and smooth operation.

[0056] Example 2: like Figures 3 to 5 As shown, the second embodiment of the photovoltaic system cleaning device of the present invention is basically the same as that of embodiment 1, except that: In this embodiment, the water spray assembly 71 includes a nozzle 711, a water pipe 712, and a steel wire rope 716. The nozzle 711 is slidably mounted on the track 4, the water pipe 712 is connected to the nozzle 711 and connected to an external water source, and the steel wire rope 716 is connected to the drive mechanism 5. A clamping mechanism 717 is provided on the nozzle 711, which is connected to the steel wire rope 716 to drive the nozzle 711 to move. In this structure, the movement of the nozzle 711 is achieved through a purely mechanical mode using the steel wire rope 716 and the clamping mechanism 717, further reducing costs.

[0057] In this embodiment, the clamping mechanism 717 includes a clamping seat 7171, a movable rod 7172, and a spring 7173. The clamping seat 7171 is fixedly connected to the nozzle 711. The movable rod 7172 passes through the clamping seat 7171, and the spring 7173 is sleeved on the movable rod 7172. A first clamping block 71711 is provided on the clamping seat 7171, and a second clamping block 71721 is provided at the lower end of the movable rod 7172. The spring 7173 forces the movable rod 7172 to drive the second clamping block 71721 to move upward so as to cooperate with the first clamping block 71711 to clamp the wire rope 716. In this structure, the elastic potential energy of the spring 7173 is used to lift the movable rod 7172 upward, so that the second clamping block 71721 cooperates with the first clamping block 71711 to clamp the wire rope 716, thereby enabling the nozzle 711 to move with the wire rope 716. Its design is ingenious.

[0058] In this embodiment, a conversion mechanism 8 is provided on the track 4 to control the connection and disconnection between the clamping mechanism 717 and the wire rope 716, so that each nozzle 711 can move individually or sequentially. The nozzle 711 collides with the conversion mechanism 8 to cause the clamping mechanism 717 to release the wire rope 716 and cause the clamping mechanisms 717 on adjacent nozzles 711 to clamp the wire rope 716. The conversion mechanism 8 includes a mounting base 81, a rotating shaft 82, an impact rod 83, and a connecting rod 84. The mounting base 81 is fixedly mounted on the track 4, the rotating shaft 82 is movably connected in the middle of the mounting base 81, and the impact rod 83 and the connecting rod 84 are horizontally slidably mounted in the mounting base 81 and respectively connected to the track 4. The two ends of the rotating shaft 82 are movably connected. When the nozzle 711 collides with the impact rod 83, it pushes the impact rod 83 to move horizontally, forcing the rotating shaft 82 to rotate. This causes one end of the insertion rod 84 to be inserted into the clamping seat 7171 on the nozzle 711, and the other end of the insertion rod 84 to be released from the clamping seat 7171 on the adjacent nozzle 711. The nozzle 711 is provided with an impact part 7111, and the clamping seat 7171 is provided with an insertion part 71712. When the insertion rod 84 is inserted into the insertion part 71712, it forces the movable rod 7172 to drive the second clamping block 71721 to move downward to release the clamping connection with the wire rope 716. In this structure, the conversion mechanism 8 is set so that each nozzle 711 can run in sequence. The action conversion of releasing the current nozzle 711 and connecting the next nozzle 711 can be completed by the physical collision between the nozzle 711 and the conversion mechanism 8. The design is ingenious and reliable. In complex outdoor environments, the pure mechanical structure is more weather-resistant and has lower maintenance costs than the electronic control mode in Example 1.

[0059] In this embodiment, the nozzle 711 is provided with a traveling wheel 7112 that slides on the track 4. In this structure, the nozzle 711 moves smoothly and steadily on the track 4 via the traveling wheel 7112.

The steel wire rope 716 is connected to the drive mechanism 5, which drives the cleaning vehicle 3 and the nozzle 711 to move synchronously. In this structure, the nozzle 711 is directly and fixedly connected to the steel wire rope 716 and moves with the steel wire rope 716 to spray water onto the photovoltaic system, making it move completely synchronously with the cleaning vehicle 3, resulting in the simplest structure.

[0061] Example 4: like Figures 8 to 10As shown, the fourth embodiment of the photovoltaic system cleaning device of the present invention is basically the same as that of embodiment 1, except that: The photovoltaic system cleaning device of this embodiment includes a photovoltaic panel unit 1 and a support 2.

The cleaning vehicle 3 is slidably mounted on the photovoltaic panel unit 1. The parking platform 6 is installed at the end of the photovoltaic system. The drive mechanism 5 is set on a parking platform 6 and is connected to the cleaning vehicle 3 to drive the cleaning vehicle 3 to move. The water spraying mechanism 7 is fixed on the support 2. When the cleaning vehicle 3 moves, the water spraying mechanism 7 sprays water to clean the photovoltaic system in segments. The water spraying mechanism 7 includes multiple nozzles 711 and water pipes 712. Each nozzle 711 is fixedly mounted at intervals on the support 2 on one side of the photovoltaic system. The water pipes 712 are connected in series with each nozzle 711 and connected to an external water source. A signal transmitter 32 is provided on the cleaning vehicle 3. Each nozzle 711 is provided with a second sensor 718 that receives a signal when it is close to the signal transmitter 32 and causes the next nozzle 711 to spray water according to the cleaning direction of the cleaning vehicle 3. In this structure, multiple fixed nozzles 711 are used to cover the entire photovoltaic system, which is low in cost and highly reliable. Each nozzle 711 receives the signal from the signal transmitter 32 on the cleaning vehicle 3 through the second sensor 718 to control the water spraying, realizing intelligent linkage of spraying water first and cleaning later, which meets the cleaning needs while saving water.

[0062] Example 5: like Figure 11 As shown, the fifth embodiment of the photovoltaic system cleaning device of the present invention is basically the same as that of embodiment 1, except that: In this embodiment, the water spraying mechanism 7 includes at least one rotating nozzle 718 and a water pipe 712. The water pipe 712 is connected to the rotating nozzle 718 and to an external water source. The rotating nozzle 718 is fixed on the bracket 2 and performs segmented water spraying cleaning on the photovoltaic system by rotating. In this structure, the rotating nozzle 718 has a large coverage area, reducing the amount of installation work.

[0063] Example 6: like Figure 12 As shown, the sixth embodiment of the photovoltaic system cleaning device of the present invention is basically the same as that of embodiment 1, except that: The photovoltaic system cleaning device of this embodiment includes a photovoltaic panel unit 1 and a support 2.

The water spraying mechanism 7 includes a nozzle 711 and a water pipe 712. The nozzle 711 is fixed on the parking platform 6, and the water pipe 712 is connected to the nozzle 711 and connected to an external water source. In this structure, water is sprayed on the cleaning areas of two adjacent cleaning vehicles 3 by the nozzle 711 fixed on the parking platform 6. The water spraying mechanism 7 does not need to move, simplifying the structure and reducing costs.

[0064] Example 7: like Figure 13 As shown, the second embodiment of the photovoltaic system cleaning device of the present invention is basically the same as that of embodiment 6, except that: In this embodiment, the drive mechanism 5 includes drive motors 51, drive wheels 52, and traction steel cables 53 in a number matching the number of cleaning vehicles 3.
