Workers need to regularly clean the system's external surfaces to remove accumulated dust, stains, and other impurities. However, existing technologies for cleaning PV storage, charging, and swapping systems using manual methods not only suffer from poor cleaning efficiency but also pose a risk of secondary environmental pollution because they cannot collect dust and stains from the system during the cleaning process. Summary of the Invention

[0004] The main objective of this invention is to propose a self-cleaning mechanism and system for a photovoltaic energy storage and charging system.

[0008] In one embodiment, the sidewall of the dust collection box is provided with a plurality of vertically spaced drain outlets, and each drain outlet is provided with a second programmable valve, any of the second programmable valves being able to switch between a drain outlet in a draining state and a drain outlet in a sedimentation separation state.

[0011] In one embodiment, the self-cleaning component includes: A dust collection pipe is sealed and connected to the dust inlet, and the opening of the dust collection pipe is set towards the outer wall of the photovoltaic energy storage and charging system.

[0023] In existing technologies, the surface cleaning and maintenance of photovoltaic, energy storage, charging, and swapping systems, as new energy infrastructure, have long relied on manual operation. Workers need to climb the equipment regularly to clean them, which not only poses risks of working at height, but also causes wastewater and dust generated during the cleaning process to easily spread into the surrounding environment, resulting in secondary pollution.

[0024] To address the aforementioned issues, the applicant discovered that manual cleaning of photovoltaic storage and charging / swapping systems not only suffers from poor cleaning efficiency but also poses a risk of secondary environmental pollution due to the inability to collect dust and dirt from the systems during the cleaning process.

[0025] This invention proposes a self-cleaning mechanism for a photovoltaic energy storage charging and switching system, as well as the photovoltaic energy storage charging and switching system itself.

[0026] Please see Figures 1 to 4 For ease of understanding, this is a self-cleaning mechanism for an optical storage, charging, and switching system. The self-cleaning mechanism can move along the outer periphery of the optical storage, charging, and switching system and clean the system. The self-cleaning mechanism of the photovoltaic energy storage and charging system includes a walking component 200, a dust collection component 300, and a self-cleaning component 400. The walking component 200 can adhere to the outer periphery of the photovoltaic energy storage and charging system and can walk along the outer wall of the photovoltaic energy storage and charging system. The dust collection component 300 is installed on the side of the walking component 200 away from the photovoltaic energy storage and charging system. A dust collection space 310 is formed inside the dust collection component 300, and a dust inlet 320 communicating with the dust collection space 310 is formed on the dust collection component 300. The self-cleaning component 400 is installed on the dust collection component 300 and communicates with the dust collection channel. The self-cleaning component 400 can extend to contact the outer wall of the photovoltaic energy storage and charging system so as to suck up and clean the dust on the outer wall of the photovoltaic energy storage and charging system when the walking component 200 adheres to the outer wall of the photovoltaic energy storage and charging system.

[0027] Specifically, the walking component 200 refers to a mobile device with magnetic or vacuum adsorption functions, which can be implemented using an electromagnet array or a negative pressure vacuum suction cup assembly. It achieves continuous movement along the outer wall of the equipment through alternating adsorption and release. The dust collection component 300 refers to a sealed container with a dust inlet channel, which can be a hollow box structure molded from engineering plastic. Its dust inlet 320 is connected to the self-cleaning component 400 to form a dust transmission path. The self-cleaning component 400 refers to a cleaning unit with a negative pressure suction function, which can be a combination of a rotating brush and a vacuum nozzle. It removes surface deposits through contact cleaning combined with airflow extraction.

[0028] As the walking component 200 moves along the outer wall of the equipment through alternating adsorption actions, the contact cleaning unit at the end of the self-cleaning component 400 maintains constant pressure contact with the equipment surface. Dust generated during cleaning is guided by negative pressure airflow into the sealed space of the dust collection component 300, preventing contaminant leakage. The dust collection component 300 is equipped with a multi-stage filtration structure, such as a combination of cyclone separator and filter screen, to achieve gas-solid separation and dust collection. The walking path can be preset according to the equipment's shape or adjusted in real time via sensors to ensure thorough cleaning coverage.

[0029] Through the above technical solutions, this application achieves automated operation of surface cleaning for photovoltaic energy storage and charging / swapping systems, effectively avoiding the safety hazards of manual operation. The enclosed dust collection system completely solves the problem of secondary pollution during the cleaning process, improving the environmental performance of equipment maintenance. The adaptive walking mechanism can adapt to shell surfaces with different curvatures, ensuring consistent cleaning results and extending the service life of the equipment.

[0030] In this embodiment, by providing a walking component 200, a dust collection component 300, and a self-cleaning component 400, the walking component 200 can adhere to the outer periphery of the optical storage and charging system during use. When the self-cleaning mechanism adheres to the outer wall of the optical storage and charging system, the self-cleaning component 400 extends to contact the outer wall of the optical storage and charging system to absorb and clean the dust on the outer wall. Simultaneously, the absorbed and cleaned dust is transported into the dust collection component 300. Thus, the present invention can use the self-cleaning mechanism to clean the optical storage and charging system, ensuring cleaning efficiency. At the same time, the dust collection component 300 collects the dust absorbed by the self-cleaning component 400, thereby avoiding dust pollution to the external environment.

[0031] In one embodiment, the dust collection component 300 includes a dust collection box 330, a solid-liquid separation component 350, and a first cleaning component 360. A dust collection space 310 is formed inside the dust collection box 330. A dust inlet 320 is formed on the wall of the dust collection box 330, and an outlet 340 is formed at the bottom of the dust collection box 330, located below the dust inlet 320. The solid-liquid separation component 350 is installed in the dust collection space 310 and is positioned close to the outlet 340. The first cleaning component 360 is installed in the dust collection space 310 and is positioned above the solid-liquid separation component 350, facing the dust inlet 320. The first cleaning component 360 is used to spray cleaning water towards the dust inlet 320 to clean and dissolve the dust collected through the dust inlet 320.

[0032] Specifically, as the self-cleaning mechanism moves along the outer wall of the photovoltaic energy storage and charging system, dust enters the interior space of the dust collection box 330 through the dust inlet 320. After the first cleaning component 360 is activated, a high-pressure water jet continuously sprays out from the direction of the dust inlet 320, washing away and dissolving the dust adhering to the vicinity of the dust inlet 320 to form a mud-water mixture. After the mixture flows into the dust collection box 330, the solid-liquid separation component 350 intercepts the settled solid particles, and the separated liquid is discharged through the bottom discharge port 340. This process achieves simultaneous operation of immediate dust cleaning and solid-liquid separation.

[0033] In this embodiment, by integrating spray cleaning and solid-liquid separation functions, wastewater purification is completed directly during the cleaning process, effectively preventing the spread of pollutants.

[0034] In one embodiment, the inner wall of the dust collection box 330 is formed with a plurality of circumferentially spaced grooves 331, all of which extend vertically and are connected to the dust collection space 310. The solid-liquid separation assembly 350 includes a first telescopic member 351, a dust collection box 352, and a flexible guide pad 354. The first telescopic member 351 is installed in the dust collection space 310, and the telescopic end of the first telescopic member 351 is vertically upward. The dust collection box 352 is housed within the dust collection space 310, and a dust collection port is formed at the top of the dust collection box 352. The dust collection box 352 slides with all the sliding grooves 331. The outer wall of the dust collection box 352 is connected to the output shaft of the first telescopic member 351. 51 can drive the dust collection box 352 to rise and fall within the dust collection space 310. A dust discharge channel is formed at the bottom of the dust collection box 352. A first programmable valve 353 is installed on the dust discharge channel. The first programmable valve 353 can switch between the dust discharge channel being open and the dust discharge channel being closed. A flexible guide pad 354 is arranged in a ring on the top of the dust collection box 352. The top of the flexible guide pad 354 is connected to the inner wall of the dust collection box 330, and the bottom is sealed to the top of the dust collection box 352.

[0035] Specifically, when the dust collection box 352 needs to discharge sediment, the first telescopic component 351 drives the dust collection box 352 to move downward along the slide 331, and the flexible guide pad 354 stretches and deforms accordingly but still remains sealed. At this time, a height difference is formed between the dust collection port at the top of the dust collection box 352 and the inner wall of the dust collection box 330, allowing the sediment to slide into the dust discharge channel under the action of gravity. The first programmable valve 353 opens the dust discharge channel according to the preset program to complete the directional discharge of solid particles. During the cleaning operation, the annular sealing structure of the flexible guide pad 354 can prevent the cleaning fluid from leaking, while the guiding effect of the slide 331 ensures that the lifting trajectory of the dust collection box 352 is accurate and avoids collision with the inner wall of the dust collection box 330.

[0036] In this embodiment, the cooperation between the sliding groove 331 and the telescopic component enables the dust collection box 352 to have high adjustability, allowing for optimization of separation efficiency according to actual working conditions. The elastic sealing design of the flexible guide pad 354 breaks through the limitations of traditional rigid connection structures, ensuring sealing while adapting to the lifting and lowering movement of the dust collection box 352, thus solving the technical challenge of dynamic sealing.

[0037] In one embodiment, the sidewall of the dust collection box 352 is formed with a plurality of vertically spaced drain outlets 355, and each drain outlet 355 is provided with a second programmable valve 356. Any second programmable valve 356 can switch between a drain outlet 355 open for drainage and a drain outlet 355 closed for sedimentation separation.

[0038] Specifically, when the dust collection box 352 collects wastewater containing dust, the second programmable valve 356 is closed. At this time, the wastewater settles in the box, forming a solid sediment layer and an upper clear liquid layer. When the water level reaches a preset height, the second programmable valve 356 corresponding to the upper drain outlet 355 opens, prioritizing the discharge of the separated clear liquid. If the amount of solid sediment exceeds a threshold, the system can switch to the lower drain outlet 355 for wastewater discharge. For example, when the dust collection box 352 is 50 cm high, drain outlets 355 can be installed at 20 cm and 35 cm respectively, optimizing solid-liquid separation efficiency through stratified drainage.

[0039] In this embodiment, multiple vertically distributed drain outlets 355 and independently controlled programmable valves can select the optimal drainage location based on real-time detection data, preventing solid material leakage and reducing the frequency of manual cleaning.

[0040] In one embodiment, a detection hole is provided on the outer wall of the dust collection box 352, a transparent part 357 is installed on the detection hole, a detection sensor 358 is provided on the outer periphery of the transparent part 357, the detection sensor 358 is positioned facing the transparent part 357, and the detection sensor 358 is used to detect the height of dust or water level in the dust collection box 352.

[0041] Specifically, the detection sensor 358 is fixed to the outer periphery of the transparent component 357, with its signal emission direction aligned with the transparent component 357 and penetrating into the dust collection box 352. As dust or wastewater gradually accumulates in the dust collection box 352 during solid-liquid separation, the detection sensor 358 analyzes changes in the reflected signal to determine in real time whether the dust accumulation height or water level has reached a preset threshold. For example, when the dust height exceeds the set upper limit, the detection sensor 358 can trigger the opening of the first programmable valve 353 in the dust discharge channel to discharge the sediment; when the water level is too high, it can activate the second programmable valve 356 of the drain outlet 355 to perform a drainage operation, thereby preventing blockage or liquid overflow inside the dust collection box 352.

[0042] In this embodiment, by combining the detection sensor 358 with the transparent component 357, the automated monitoring of the material level inside the dust collection box 352 is achieved, solving the problem of untimely manual intervention and avoiding the risk of equipment failure due to overcapacity.

[0043] In one embodiment, the first cleaning component 360 includes a first water distribution ring 361 and a plurality of first high-pressure valves 362. The first water distribution ring 361 is located near the dust inlet 320 and can form a hollow channel. A plurality of first water outlets are formed on the side of the first water distribution ring 361 facing the dust inlet 320 and are distributed circumferentially at intervals along the first water distribution ring 361. The water distribution ring is connected to a water storage tank through a water supply pipeline. The number of first high-pressure valves 362 is the same as the number of first water outlets and they are arranged in a one-to-one correspondence. All first high-pressure valves 362 are arranged facing the dust inlet 320. The cleaning water stored in the water storage tank can be dispersed by the first water distribution ring 361 and sprayed out from each of the first high-pressure valves 362 toward the dust inlet 320 to clean the dust in the dust inlet 320. The wastewater formed by cleaning can flow into the dust collection box 330.

[0044] Specifically, when dust from the outer wall of the photovoltaic-storage-charging-swapping system enters the dust collection space 310 through the dust inlet 320, the cleaning water in the water tank is pressurized by the pump and then transported to the hollow channel of the first water distribution ring 361 through the water supply pipeline. After the water flow is evenly distributed within the water distribution ring, it is sprayed out from multiple circumferentially spaced first water outlets. At the same time, the first high-pressure valve 362 opens and adjusts the water pressure to the range of 0.8-1.2 MPa. The high-pressure water flow directly impacts the dust accumulated in the dust inlet 320, decomposing the hardened dirt into a fluid state. The dissolved wastewater flows along the inner wall of the dust collection box 330 into the bottom discharge port 340 under the action of gravity. During the process, the solid-liquid separation component 350 performs preliminary treatment on the mixed flow.

[0045] In this embodiment, the combination of a water distribution ring and a high-pressure valve enables comprehensive cleaning of the interior of the dust inlet 320, while the wastewater is directed into the dust collection box 330 for centralized treatment, thus avoiding the risk of environmental pollution.

[0046] In one embodiment, the self-cleaning component 400 includes a dust collection pipe 410, a dust suction component 420, a plurality of second telescopic components 430, a water storage tank 440, and a second water distribution ring 450. The dust collection pipe 410 is sealed and connected to the dust inlet 320, with the opening of the dust collection pipe 410 facing the outer wall of the photovoltaic energy storage and charging system. The dust suction component 420 is installed inside the dust collection pipe 410 and is positioned close to the dust inlet 320. The plurality of telescopic components are circumferentially spaced around the outer periphery of the dust collection box 330, and all the second... One end of the telescopic component 430 is hinged to the dust collection box 330, and the other end is hinged to the opening of the dust collection pipe 410. The water storage tank 440 is installed on the outer periphery of the dust collection box 330. The first water distribution ring 361 is connected to the water storage tank 440 through a pipeline. The second water distribution ring 450 is installed on the dust collection pipe 410. The second water distribution ring 450 forms a hollow channel. The second water distribution ring 450 is set close to the opening of the dust collection pipe 410. Multiple second high-pressure valves are provided on the second water distribution ring 450 at intervals along the circumference.

[0047] Specifically, when the self-cleaning mechanism moves along the outer wall of the photovoltaic energy storage and charging system, the second telescopic component 430 automatically adjusts the contact angle between the dust collection pipe 410 opening and the wall surface according to the shape of the outer wall. The suction component 420 creates a negative pressure inside the dust collection pipe 410, drawing dust from the outer wall into the dust collection space 310 through the opening. The second water distribution ring 450 is activated simultaneously, spraying high-pressure water onto the outer wall through the second high-pressure valve to flush away stubborn stains. The water storage tank 440 supplies water to the first water distribution ring 361 and the second water distribution ring 450 simultaneously through pipelines, ensuring the cleaning process continues. The wastewater and dust mixture generated during cleaning enters the dust collection box 330 through the dust inlet 320 and is then classified and treated by the solid-liquid separation component 350.

[0048] In this embodiment, the hinged structure between the second telescopic member 430 and the dust collection pipe 410 allows the pipe opening to adaptively conform to the outer wall surface with different curvatures. Meanwhile, existing technologies lack integrated devices for simultaneous dust collection and rinsing. This solution, through the coordinated operation of the water distribution ring and the dust collection member 420, collects wastewater simultaneously while rinsing away stains, avoiding secondary pollution caused by liquid splashing.

[0049] In one embodiment, the self-cleaning component 400 further includes a plurality of self-cleaning brushes 460, all of which are circumferentially spaced at the opening of the dust collection pipe 410.

[0050] Specifically, when the self-cleaning mechanism travels along the outer wall of the photovoltaic energy storage and charging system, the bristles or scraper of the self-cleaning brush 460 directly contact the outer wall surface. The movement of the traveling component 200 generates friction, stripping away dust and stains adhering to the surface. The stripped dust is then drawn into the dust collection space 310 by the negative pressure of the dust collection pipe 410, and the circumferential distribution design of the self-cleaning brush 460 avoids cleaning blind spots. Furthermore, the self-cleaning brush 460 works in conjunction with the high-pressure water spray assembly of the second water distribution ring 450, allowing the brushing action and water rinsing to occur simultaneously, thus improving the dissolution efficiency of stubborn stains.

[0051] In one embodiment, the walking component 200 includes a plurality of third telescopic members 210, a plurality of fourth telescopic members 220, and a plurality of automatic suction cups 230. The plurality of third telescopic members 210 are distributed circumferentially at intervals on the outer periphery of the dust collection box 330, and the telescopic ends of all third telescopic members 210 can extend and retract along a first direction. All third telescopic members 210 are on the same side as the second telescopic members 430 and are distributed at intervals. The number of fourth telescopic members 220 is the same as the number of third telescopic members 210 and is arranged in a one-to-one correspondence. Each fourth telescopic member 220 can extend and retract along a second direction, and the telescopic ends of each fourth telescopic member 220 are arranged facing the outer wall of the photovoltaic energy storage and charging system. The number of automatic suction cups 230 is the same as the number of fourth telescopic members 220 and is arranged in a one-to-one correspondence. All automatic suction cups 230 can switch between an adsorption state and a walking state on the photovoltaic energy storage and charging system.

[0052] Specifically, the third telescopic member 210 is distributed at intervals along the outer periphery of the dust collection box 330. By synchronously telescopically extending and retracting, it adjusts the overall position of the traveling component 200, enabling the self-cleaning mechanism to adapt to outer wall surfaces with different curvatures. The fourth telescopic member 220 is arranged in a one-to-one correspondence with the third telescopic member 210, and its telescopic direction is perpendicular to the third telescopic member 210. It is used to precisely push the automatic suction cup 230 onto the outer wall surface in the adsorption state. The automatic suction cup 230 achieves step-by-step movement by alternately switching between adsorption and release states. For example, when some suction cups remain adsorbed, the remaining suction cups can detach from the surface and move along a predetermined trajectory to the next adsorption point, thereby achieving continuous movement of the mechanism.

[0053] In some specific embodiments, the extension stroke of the third telescopic member 210 can be 50-200 mm, and the extension direction of the fourth telescopic member 220 is parallel to the normal direction of the outer wall of the photovoltaic energy storage and charging system. The adsorption surface of the automatic suction cup 230 can be equipped with a flexible sealing ring to improve airtightness, and its vacuum pipeline can be connected to a negative pressure generator through a solenoid valve to achieve rapid switching of the adsorption state.

[0054] In this embodiment, the cleaning mechanism achieves autonomous movement on complex surfaces through the coordinated control of multiple sets of telescopic components and the automatic suction cup 230. Simultaneously, the mechanized suction movement avoids the safety hazards associated with manual operation. Furthermore, the alternating suction action of the suction cup assembly ensures that the mechanism maintains stable support at at least three contact points throughout its movement, significantly improving the reliability of the cleaning operation.

[0055] Based on the same technical concept, in a second aspect, the present invention also proposes a photovoltaic energy storage charging and switching system that applies the self-cleaning mechanism of the photovoltaic energy storage charging and switching system of the first aspect.

[0056] Specifically, when dust adheres to the outer surface of the photovoltaic-storage-charging-swapping system, the traveling component 200 moves along the outer wall through adsorption, causing the dust collection component 300 to move synchronously. The self-cleaning component 400 continuously contacts the outer wall surface during movement, using negative pressure to draw dust into the dust collection space 310 through the dust inlet 320. The dust collection component 300 is equipped with a solid-liquid separation assembly 350, which can separate and process the inhaled mixed pollutants. The traveling component 200 employs a multi-set telescopic suction cup structure, achieving continuous movement through alternating adsorption and release, ensuring that the cleaning operation covers the entire outer surface of the system.

[0057] In this embodiment, a mechanical automated cleaning device is used to simultaneously remove and collect surface dust, eliminating the safety hazards of manual operation and avoiding secondary pollution caused by the spread of cleaning wastewater and dust.

[0058] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
