Description

Technical Field

[0001] This invention relates to the field of solar photovoltaic panel maintenance technology, and in particular to an energy-saving circulating cleaning device for solar photovoltaic panels. Background Technology

[0002] A solar photovoltaic (PV) panel is a solar panel composed of one or more solar cells. A solar cell is a semiconductor device that converts light into electricity. It converts solar radiation energy shining on its surface into direct current (DC). Solar panels are the most basic component of a photovoltaic (PV) power generation system / product and the core part of a solar PV power generation system. Its main function is to convert solar energy into electrical energy and store it in a battery. A common problem after PV panel installation is dust accumulation on the panel surface. As dust accumulates on the panel surface, it increases the thermal resistance of the PV panel, becoming a heat insulation layer on the PV panel and affecting its heat dissipation. Moreover, dust adhering to the panel surface can block, absorb, and reflect light. Clean PV panels have at least 5% higher output power than dusty panels. The surface of PV panels is mostly made of glass. When moist, acidic, or alkaline dust adheres to the glass cover, the glass surface will be slowly corroded. Therefore, regular cleaning and maintenance of solar PV panels are necessary. Traditional cleaning methods for PV panel surfaces usually involve personnel using hand-held cleaning brushes to scrub the surface and rinsing the PV panel surface with water from an external water source.

[0003] However, traditional cleaning methods often encounter some problems in actual implementation:

[0004] 1. Existing cleaning brushes use a lot of water to rinse during the cleaning process, which improves the cleanliness. However, water rinsing is prone to waste of water resources, and the installation locations of photovoltaic panels are mostly in arid areas, which have a large demand for water resources.

[0005] 2. The installation area of ​​photovoltaic panels is relatively large, and it is difficult to maintain high-intensity wiping for a long time by manual wiping. In hot weather, people working at high positions are prone to heatstroke, fainting and other phenomena, and their own safety cannot be guaranteed.

[0006] Therefore, there is an urgent need for an energy-saving circulating cleaning device for solar photovoltaic panels to solve the above-mentioned defects. Summary of the Invention

[0023] II. Beneficial Effects

[0024] 1. The present invention discloses an energy-saving circulating cleaning device for solar photovoltaic panels, which fixes the solar photovoltaic panels in a U-shaped edge-wrapping manner (the filter circulation frame, water outlet component, and positioning component form a U-shaped fixed component). On the one hand, it temporarily collects the rainwater, and on the other hand, it can serve as a temporary track for the cleaning components (for improving the conveying track in subsequent cleaning processes). The filter circulation frame and water outlet component work together to filter and circulate the cleaning water in a single cleaning process, thereby improving the utilization rate of water resources, reducing water waste, and increasing energy saving rate.

[0025] 2. The energy-saving circulating cleaning device for solar photovoltaic panels described in this invention uses a one-way wiping method for the cleaning components, which simulates the wiping action of a person and avoids the phenomenon that some dirt is pushed back and re-adheded due to two-way wiping. By replacing manual wiping with mechanical cleaning, the workload remains constant and is not afraid of high temperature weather.

[0026] 3. The energy-saving circulating cleaning device for solar photovoltaic panels described in this invention has an adaptive structure for the cleaning components, which do not require one-to-one matching production with the fixed components installed on the photovoltaic panels. A single cleaning component can sequentially assemble and clean multiple sets of fixed components, thereby reducing production costs. Attached Figure Description

[0036] Embodiments of the present invention will now be described with reference to the accompanying drawings. In this process, to ensure clarity and convenience, we may exaggerate the width of lines or the size of constituent elements in the drawings.

[0037] Furthermore, the terms used below are defined based on the functionality of this invention and may vary depending on the user's, operator's, or conventions. Therefore, these terms are defined based on the entire contents of this specification.

[0038] like Figures 1 to 8 As shown, an energy-saving circulating cleaning device for solar photovoltaic panels includes a filter circulation frame 1, a positioning component 3 is provided between the filter circulation frame 1 and the water outlet component 2, the filter circulation frame 1, the water outlet component 2 and the positioning component 3 are arranged in a U-shape, and a cleaning component 4 is provided above the positioning component 3, and the positioning component 3 and the cleaning component 4 cooperate with each other.

[0039] The positioning component 3 includes a positioning rod 31, a rack 32, a guide track 33, and a touch component 34. A U-shaped slot is provided on the inner side of the positioning rod 31, and a rack 32 is installed on the outer side of the positioning rod 31. The guide track 33, corresponding to the position of the rack 32, is opened on the side wall of the positioning rod 31. The front end of the guide track 33 is open to facilitate the insertion of the L-shaped slider. The guide track 33 plays a limiting role in the movement of the cleaning component 4. The touch component 34 is installed at the upper end of the positioning rod 31.

[0040] The cleaning component 4 includes a housing 41, a connecting component 42, a wiping cloth 43, a rotating frame 45, and a drive gear set 46. The connecting component 42 is slidably arranged inside the housing 41, and the wiping cloth 43 is arranged at the lower end of the connecting component 42. The rotating frame 45 is rotatably arranged at the left and right ends of the housing 41. The rotating frame 45 is rotatably connected, ensuring that when the cleaning component 4 is not in use, rotating the rotating frame 45 will cause the drive gear set 46 to face upwards, ensuring that the lower end of the housing 41 is placed in close contact with the table or ground, avoiding damage caused by the drive gear set 46 contacting the table or ground when the cleaning component 4 is placed. The drive gear set 46 is installed on the rotating frame 45, and the drive gear set 46 cooperates with the rack 32. The connecting component 42 cooperates with the touch component 34, and the contact between the connecting component 42 and the touch component 34 controls the height of the wiping cloth 43, ensuring that the wiping cloth 43 is in a unidirectional wiping state. An L-shaped slider is provided on the rotating frame 45, and the position of the L-shaped slider corresponds to that of the guide trajectory 33.

[0041] Specifically, this application is assembled with a solar photovoltaic panel. The assembly process is as follows: the U-shaped slot on the positioning rod 31 is inserted into the side end of the photovoltaic panel, and the positioning rod 31 is locked to the side end of the photovoltaic panel using existing locking components. Then, the filter circulation frame 1 is assembled with the lower end of the positioning rod 31, and the water outlet component 2 is assembled with the upper end of the positioning rod 31. After assembly, the filter circulation frame 1 collects some of the rainwater passing through the photovoltaic panel. The cleaning component 4 of this application is used to clean the photovoltaic panel periodically. The cleaning process is as follows: the L-shaped slider is embedded in the guide track 33. At this time, the drive gear set 46 and the rack 32 mesh. Through the engagement of the drive gear set 46 and the rack 32, the housing 41 is driven to move back and forth along the upper surface of the photovoltaic panel. When moving from front to back, the connecting component 42 is in the highest locked position. At this time, the wiping cloth 43 is not in contact with the photovoltaic panel. When the housing 41 moves to the rearmost side, the connecting component 42 is unlocked and lowered, allowing the wiping cloth 43 to contact the photovoltaic panel. The surface of the photovoltaic panel is in contact with the water outlet component 2, which is powered on and emits water. Subsequently, driven by the drive gear set 46, the housing 41 moves forward. Under the impact of the water flow, the surface of the photovoltaic panel is wiped and cleaned by the wiping cloth 43. Since the water outlet component 2 is a delayed water-stopping structure, the water outlet component 2 stops emitting water only after the wiping cloth 43 has moved forward a certain distance. In this application, the water is transported in a circulating manner during a single cleaning process, which reduces the waste of water resources. At the same time, mechanical wiping replaces manual wiping, which greatly reduces the labor intensity of personnel. In addition, the cleaning component 4 in this application adopts a unidirectional wiping method, which simulates the wiping action of personnel and avoids the phenomenon of some dirt being pushed back due to bidirectional wiping, thus improving the cleanliness. Furthermore, the cleaning component 4 in this application is an adaptive structure, which does not require one-to-one matching with the fixed components (filter circulation frame 1, water outlet component 2, positioning component 3) installed on the photovoltaic panel. A single cleaning component 4 can assemble and clean multiple fixed components in sequence, which reduces production costs.

[0042] The filter circulation frame 1 includes a collection frame 11 and a filter assembly 12. The upper end of the collection frame 11 is provided with a water collection port. The filter assembly 12 located below the water collection port is horizontally slidably disposed inside the collection frame 11. The lower end of the collection frame 11 is provided with a drain port. After a single cleaning, the drain port is opened to discharge the sewage. The front end of the collection frame 11 is provided with an external water inlet. When the collected rainwater is insufficient for a single cleaning, the external water inlet is opened to inject an external water source. The upper part of the water collection port has a flared structure, and the lower part of the water collection port has a structure that gradually slopes forward from top to bottom. The structural design of the water collection port reduces the evaporation of rainwater after collection.

[0043] Specifically, the collection box 11 is used to collect rainwater and temporarily store external water sources. When the collected rainwater is insufficient, some external water is injected to obtain the clean water used in this cleaning process. Then, in conjunction with the water outlet component 2, the water is circulated and transported for flushing. Solid impurities mixed in are filtered and intercepted by the filter component 12. Compared with the one-time flushing with water pipes in the prior art, this application greatly saves water resources, and the collection of rainwater is also to reduce the waste of water resources.

[0044] The water outlet assembly 2 includes an overlap plate 21, a nozzle 22, a connecting pipe 23, a dustproof frame 24, a delivery pump 25, a delivery pipe 26, and a power supply unit 27. The overlap plate 21 has a collection cavity inside, which is connected to the nozzle 22. The lower end of the collection cavity is connected to the connecting pipe 23. The dustproof frame 24 is installed at the front end of the overlap plate 21. The delivery pump 25 is installed inside the dustproof frame 24. The delivery pump 25, the connecting pipe 23, and the delivery pipe 26 are connected and installed together. The delivery pump 25 is electrically connected to the power supply unit 27. The end of the delivery pipe 26 away from the delivery pump 25 extends into the interior of the collection frame 11.

[0045] The power supply group 27 includes an insulating frame 271, a power supply 272, and a time delay switch 273. The insulating frame 271 is installed on the right side of the dustproof frame 24, and the power supply 272 and the time delay switch 273 inside the insulating frame 271 are electrically connected to the delivery pump 25. The time delay switch 273 is a touch-type time delay switch structure in the prior art, which has the function of delaying circuit breaking, ensuring that the delivery pump 25 is still energized during the process of the housing 41 moving forward a short distance in this application, which is beneficial for wiping with the wiping cloth 43.

[0046] Specifically, when the housing 41 moves to the rearmost side, it comes into contact with the time delay switch 273. At this time, the delivery pump 25 is energized to draw water out of the collection frame 11 and spray it out from the nozzle 22, thereby rinsing the surface of the photovoltaic panel.

[0047] The positioning rod 31 has an insertion block at its front end. The insertion block is inserted into the collection frame 11. After the positioning rod 31 and the collection frame 11 are combined, the position is locked by the connector 35. The positioning rod 31 has a threaded post at its rear end. The rear end of the threaded post passes through the overlapping plate 21 and is threadedly locked to the threaded cap.

[0048] The connector 35 includes a connecting plate, a first threaded component, and a second threaded component. The first threaded component passes through the connecting plate and is threadedly connected to the positioning rod 31. The second threaded component passes through the connecting plate and is threadedly connected to the filter circulation frame 1.

[0049] The upper end of the positioning rod 31 is provided with a drainage groove, and the lower end of the drainage groove is aligned and connected to the inside of the collection frame 11. The side wall of the positioning rod 31 is provided with a flap via a hinge. The flap is positioned corresponding to the rack 32. The flap is used to cover and seal the unused rack 32, reducing the possibility of the rack 32 rusting.

[0050] Specifically, the connection method between the positioning rod 31, the collection frame 11, and the overlapping plate 21 is as follows: the collection frame 11 is connected to the insertion block so that the positioning rod 31 and the collection frame 11 fit together. Then, the connecting piece 35 is used to lock the position between the positioning rod 31 and the collection frame 11 for the second time. After that, the overlapping plate 21 is sleeved on the threaded post, and the threaded cap is used to thread the protruding part of the threaded post to lock the position between the positioning rod 31 and the overlapping plate 21.

[0051] The touch assembly 34 includes a contact plate 341 and an extrusion frame 342. The contact plate 341 is installed on the upper rear side of the positioning rod 31, and the extrusion frame 342 is installed on the upper front side of the positioning rod 31. A rotatable connecting roller is provided on the extrusion frame 342.

[0052] The connecting assembly 42 includes a movable plate 421, a return spring 422, a pressing block 423, a locking hook 424, and a built-in spring 425. The movable plate 421 is slidably disposed inside the housing 41. The return spring 422 connects the movable plate 421 to the housing 41, and the return spring 422 always maintains a downward pushing tendency on the movable plate 421. The pressing block 423 is installed at the front end of the movable plate 421, and the pressing block 423 is positioned corresponding to the pressing frame 342. The rear end of the movable plate 421 is open. An L-shaped groove is provided, which engages with the lower end of the locking hook 424 for locking. The upper end of the locking hook 424 is slidably disposed in the movable groove opened in the housing 41, and an internal spring 425 is connected between the movable groove and the locking hook 424. The internal spring 425 always maintains a backward pushing tendency on the locking hook 424. The locking hook 424 is positioned corresponding to the contact plate 341. The lower end of the movable plate 421 is connected to the wiping cloth 43 by Velcro, which allows the wiping cloth 43 to be removed for cleaning or replacement after it becomes soiled.

[0053] Specifically, when the housing 41 moves to the rearmost side, the locking hook 424 contacts the contact plate 341, and under the pressure of the contact plate 341, the locking hook 424 retracts into the movable groove. At this time, the L-shaped groove and the locking hook 424 are no longer locked together. The movable plate 421 moves downward under the action of the return spring 422, so that the wiping cloth 43 is exposed and contacts the upper surface of the photovoltaic panel, wiping and cleaning the upper surface of the photovoltaic panel. When the housing 41 moves to the frontmost side, the inclined surface of the pressing block 423 contacts the connecting roller, and under the pressure of the connecting roller, the pressing block 423 moves upward, so that the locking hook 424 re-locks into the L-shaped groove, and the wiping cloth 43 retracts into the housing 41, ensuring that the wiping cloth 43 and the upper surface of the photovoltaic panel are in a one-way wiping state.

[0054] The drive gear set 46 includes a drive motor 461 and a gear 462. The drive motor 461 is mounted on the rotating frame 45 via a motor mount. The gear 462 is mounted on the output shaft of the drive motor 461 and meshes with the rack 32.

[0055] Specifically, the drive motor 461 drives the gear 462 to rotate. With the meshing of the gear 462 and the rack 32, and the L-shaped slider sliding on the guide track 33, the cleaning component 4 moves back and forth along the upper surface of the photovoltaic panel.

[0056] Work process:

[0057] Assembly: Attach the positioning rod 31 to the side of the photovoltaic panel, lock the positioning rod 31 to the side of the photovoltaic panel using the existing locking mechanism, assemble and lock the collection frame 11 to the lower end of the positioning rod 31, and assemble and lock the overlapping plate 21 to the upper end of the positioning rod 31. Assembly is complete.

[0058] Cleaning: The cleaning component 4 and the positioning component 3 are assembled (the L-shaped slider is embedded in the guide track 33, and the gear 462 meshes with the rack 32). The drive motor 461 drives the gear 462 to rotate. With the cooperation of the gear and rack, the housing 41 moves back and forth along the upper surface of the photovoltaic panel (during the movement, when moving backward, the wiping cloth 43 is hidden, and when moving forward, the wiping cloth 43 is extended downward). The synchronously moving wiping cloth 43 wipes the surface of the photovoltaic panel in one direction. At the same time, the water outlet component 2 rinses the surface of the photovoltaic panel, thereby cleaning.

[0059] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
