Description

Technical Field

[0001] This invention relates to the field of solar panel cleaning technology, and specifically to a solar panel cleaning system for a food delivery vehicle. Background Technology

[0002] Currently, the cleaning methods for solar panels used in vehicles (such as catering trucks) mainly rely on fixed brush cleaning or regular manual cleaning.

[0003] While fixed brush bristles can remove loose dirt like dust during regular cleaning, their cleaning effect is limited when faced with stubborn, firmly attached stains such as bird droppings and oil stains. These stains often remain on the solar panels, affecting their photovoltaic conversion efficiency. Manual cleaning can handle such stains, but it is inefficient, costly, and difficult to perform in real-time while the vehicle is in motion. Furthermore, some existing vehicle-mounted cleaning devices have scrapers that are easily contaminated and lack self-cleaning properties, potentially leading to secondary stain adhesion and reducing long-term reliability.

[0004] To address this, we propose a solar panel cleaning system for food delivery trucks. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a solar panel cleaning system for food delivery vehicles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A solar panel cleaning system for a food delivery truck includes: A solar panel, wherein a moving mechanism is provided on the solar panel; A cleaning block is connected to the movable end of the moving mechanism and moves along the surface of the solar panel under the drive of the moving mechanism; the bottom wall of the cleaning block has multiple cleaning grooves. Multiple lifting mechanisms, each of which is disposed within one of the cleaning tanks; the lifting mechanism includes: Wedge-shaped blocks symmetrically fixed to the inner wall of the cleaning tank; The two wedge-shaped blocks slide through the box body together, and springs are symmetrically fixed to the side walls of the box body. The springs are fixedly connected to the inner wall of the cleaning tank. Multiple bristles are fixed to the bottom wall of the box, and vertical rods are symmetrically slidably connected through the inner wall of the box. Wedge-shaped holes are opened in the inner wall of the vertical rods, and scrapers are fixed to the bottom wall of the vertical rods. The bottom wall of the box has symmetrical through holes for the scraper to pass through.

[0007] Preferably, the top wall of the box is symmetrically provided with connecting holes, and each connecting hole is rotatably connected to a rotating shaft. A crossbar is fixedly connected to the side wall of the rotating shaft, and a push post is fixedly connected to the side wall of the crossbar. A rectangular frame is slidably connected to the inner side wall of the connecting hole, and a U-shaped rod is fixedly connected to the side wall of the rectangular frame.

[0008] Preferably, a gear is fixed to the side wall of the rotating shaft, a connecting frame is fixed to the U-shaped rod, the connecting frame has a Y-shaped structure when viewed from above, a U-shaped rod is fixed to the connecting frame, and a processing plate is symmetrically fixed to the bottom end of the U-shaped rod.

[0009] Preferably, the processing plate has a groove on its side wall, and a scraper is elastically connected to the inner wall of the groove by multiple magnetic springs.

[0010] Preferably, a rectangular tube is symmetrically fixed to the top wall of the box, a piston is slidably connected inside the rectangular tube, the top wall of the vertical rod passes through the inner wall of the box and is fixed to the piston, a rectangular tube is fixedly connected to one side wall of the rectangular tube, a piston is slidably connected inside the rectangular tube, and a rack is fixed to the side wall of the piston.

[0011] Preferably, the gear and rack are meshed, and the push post slides against the inner sidewall of the rectangular frame.

[0012] Preferably, the wedge block and the adjacent wedge hole are embedded in the sliding mechanism.

[0013] Preferably, a liquid storage tank is fixedly connected to the inner wall of the top of the cleaning tank, and the liquid storage tank is filled with cleaning fluid. Multiple nozzles are embedded in the inner wall of the through hole. A first one-way pipe and a second one-way pipe are fixedly connected to the top side wall of the rectangular cylinder. The first one-way pipe is fixedly connected to the liquid storage tank. One end of the second one-way pipe is a single pipe, and the other end is a multi-pipe. The second one-way pipe is fixedly connected to multiple adjacent nozzles.

[0014] Preferably, it also includes a food delivery vehicle, on which multiple top columns are fixedly connected, and the solar panels are fixedly connected to the top columns.

[0015] Preferably, the moving mechanism includes: Two sets of support legs are symmetrically fixed to the frame of the solar panel. Each set of support legs consists of two legs, and each set of support legs is fixed to an electric guide rail. An electric slider is slidably fitted on the electric guide rail. A synchronizing rod is fixed between the two electric sliders. An electric push rod is fixed to the bottom wall of the electric slider. The movable end of the electric push rod is fixed to a cleaning block.

[0016] Compared with existing technologies, the advantages of this invention are: 1. The system automatically triggers the scraper mechanism by changing the brush bristle resistance. When encountering stubborn stains such as bird droppings, the wedge block engages with the wedge hole on the vertical rod to drive the scraper down and scrape the stains in a targeted manner. This achieves adaptive switching between regular cleaning and deep scraping modes, improving the cleaning ability for complex stains and helping to maintain the long-term high efficiency of light transmission on the surface of the solar panel. 2. The system can achieve automatic cleaning during scraper operation: when the scraper moves upward, the scraper blades closely adhere to the surface and scrape away the attached dirt; when the scraper moves downward, the scraper blades automatically move away to avoid interfering with the scraping action. This mechanism effectively prevents dirt from accumulating on the scraper and re-contaminating the surface, improving the reliability and continuity of the cleaning process; 3. The reciprocating motion of the vertical rod synchronously drives the piston mechanism, which precisely sprays the cleaning fluid in the storage tank onto the scraper's action area through the nozzle. This allows for the softening of stubborn stains while scraping, forming a "sweeping, scraping, and rinsing" linkage operation process. This improves the removal effect on hardened stains and eliminates the need for external power or manual intervention, achieving a fully automatic and efficient cleaning process.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Reference Figures 1-6 A solar panel cleaning system for food delivery trucks, comprising: Solar panel 3, a cleaning block 9 is installed on the solar panel 3 via a moving mechanism, and the bottom wall of the cleaning block 9 has multiple cleaning grooves 10; Each cleaning tank 10 is equipped with an enhancement mechanism 5 to improve the performance of the solar panels; Upgrade mechanism 5 includes: Wedge-shaped blocks 51 are symmetrically fixed to the inner sidewall of the cleaning tank 10; Two wedge-shaped blocks 51 slide through the housing 52. Springs 53 are symmetrically fixed to the side wall of the housing 52. Springs 53 are fixedly connected to the inner wall of the cleaning groove 10. Springs 53 have a small stiffness coefficient. When the bristles 58 encounter a preset resistance, the housing 52 moves relative to the cleaning groove 10, causing one of the wedge-shaped blocks 51 and the corresponding wedge-shaped hole 55 to slide into the cleaning groove 10. This drives the vertical rod 54 and the scraper 56 to extend downwards to perform the scraping action. Multiple bristles 58 are fixed to the bottom wall of the box 52, and vertical rods 54 are symmetrically slidably connected through the inner wall of the box 52. Wedge-shaped holes 55 are opened on the inner wall of the vertical rods 54, and scrapers 56 are fixed to the bottom wall of the vertical rods 54. The bottom wall of the box 52 has symmetrical through holes 57 for the scraper 56 to pass through.

[0021] The top wall of the housing 52 is symmetrically provided with connection holes 66. Each connection hole 66 is rotatably connected to a rotating shaft 67. A crossbar 68 is fixed to the side wall of the rotating shaft 67. A push post 69 is fixed to the side wall of the crossbar 68. A rectangular frame 610 is slidably connected to the inner side wall of the connection hole 66. A U-shaped rod 611 is fixed to the side wall of the rectangular frame 610.

[0022] A gear 612 is fixed to the side wall of the rotating shaft 67, and a connecting frame 75 is fixed to the U-shaped rod 611. The connecting frame 75 has a Y-shaped structure when viewed from above. A U-shaped rod 74 is fixed to the connecting frame 75, and a processing plate 71 is symmetrically fixed to the bottom end of the U-shaped rod 74.

[0023] The processing plate 71 has a groove 72 on its side wall. The inner wall of the groove 72 is elastically connected to a scraper 76 by multiple magnetic springs 73. The magnetic springs 73 are existing technology. After the magnetic springs 73 are energized, due to the phenomenon of electromagnetic induction, the magnetic springs 73 interact with the current in the external magnetic field to generate different magnitudes of tension to control the stretching deformation and movement state of the magnetic springs 73. The solar panel cleaning system of the catering vehicle also includes an acceleration sensor, which is electrically connected to the magnetic springs 73 to detect the movement direction of the processing plate 71 and control the on and off of the magnetic springs 73.

[0024] A rectangular cylinder 61 is symmetrically fixed to the top wall of the housing 52. A piston 62 is slidably connected inside the rectangular cylinder 61. The top wall of the vertical rod 54 passes through the inner wall of the housing 52 and is fixedly connected to the piston 62. A rectangular cylinder 63 is fixedly connected through the side wall of the rectangular cylinder 61. A piston 64 is slidably connected inside the rectangular cylinder 63. A rack 65 is fixedly connected to the side wall of the piston 64. By setting the inner diameter of the rectangular cylinder 61 and the rectangular cylinder 63, when the displacement of the piston 62 is small, the piston 64 can obtain a double displacement distance.

[0025] The gear 612 and the rack 65 are meshed and connected, and the push post 69 slides against the inner wall of the rectangular frame 610.

[0026] The wedge block 51 and the adjacent wedge hole 55 are engaged and slid.

[0027] A liquid storage tank 81 is fixedly connected to the inner wall of the top of the cleaning tank 10. The liquid storage tank 81 is filled with cleaning fluid. Multiple nozzles 84 are embedded in the inner wall of the through hole 57. A first one-way pipe 82 and a second one-way pipe 83 are fixedly connected to the top side wall of the rectangular cylinder 61. The first one-way pipe 82 is fixedly connected to the liquid storage tank 81. One end of the second one-way pipe 83 is a single pipe, and the other end is a multi-pipe. The second one-way pipe 83 is fixedly connected to the multiple adjacent nozzles 84. The first one-way pipe 82 only allows the cleaning fluid in the liquid storage tank 81 to enter the rectangular cylinder 61, and the second one-way pipe 83 only allows the cleaning fluid in the rectangular cylinder 61 to enter the multiple nozzles 84 and be sprayed out.

[0028] The entire system is installed on the food delivery vehicle 1, and the solar panels 3 are fixed to the top of the vehicle body by multiple top columns 2.

[0029] The moving mechanism includes two sets of support feet 4 symmetrically fixed to the frame of the solar panel 3. Each set of support feet 4 is equipped with an electric guide rail 11, and an electric slider 12 is slidably mounted on the guide rail. The two electric sliders 12 are connected by a synchronizing rod 14. An electric push rod 13 is mounted at the bottom of the electric slider 12, and its movable end is fixed to the cleaning block 9, thereby realizing the controllable movement of the cleaning block 9 in the horizontal and vertical directions.

[0030] In this invention, during the use of the food delivery cart 1, the cleaning block 9 is driven to move horizontally by the moving mechanism, and under the action of the electric push rod 13, the bristles 58 at the bottom of the cleaning block 9 slide against the surface of the solar panel 3, thereby cleaning and removing impurities from the surface of the solar panel 3.

[0031] During the operation of the food delivery vehicle 1, the moving mechanism drives the cleaning block 9 to move horizontally along the surface of the solar panel 3, and the electric push rod 13 presses down to make the brush bristles 58 stick tightly to the panel surface for routine cleaning.

[0032] When encountering firmly attached stains such as bird droppings, the bristles 58 will experience significant resistance. Under the action of friction, the housing 52 compresses a corresponding spring 53 and generates a lateral displacement, causing a wedge block 51 to slide against the embedded sliding wedge hole 55 after moving a certain distance. This pushes the vertical rod 54 downward, thereby causing the scraper 56 to press down and contact the stained area.

[0033] At this time, the vertical rod 54 will also drive the piston 62, which is fixed to it, to slide a certain distance inside the rectangular tube 61. Since the inner diameter of the rectangular tube 61 is much larger than that of the rectangular tube 63, the small displacement of the piston 62 in the rectangular tube 61 can cause the piston 64 to obtain a multiple displacement inside the rectangular tube 63. That is, the piston 64 drives the rack 65, which is fixed to it, to move a multiple distance in the horizontal direction. The rack 65 will then drive the gear 612, which is meshed with it, to rotate by a certain angle. The gear 612 will then drive the rotating shaft 67, which is fixed to it, to rotate. The rotating shaft 67, through the horizontal rod 68 fixed to its side wall, drives the push column 69 to move synchronously. The push column 69 then drives the sliding rod 68 to move synchronously. The rectangular frame 610 moves back and forth vertically, which drives the U-shaped rod 611 fixed to it to move back and forth vertically. The U-shaped rod 611 will then drive the processing plate 71 to move synchronously through the connecting frame 75 and the U-shaped rod 74. The magnetic spring 73 is electrically connected to an acceleration sensor. When the processing plate 71 moves downward, the magnetic spring 73 is energized and contracts under the action of the acceleration sensor, thereby driving the scraper 76 away from the scraper 56. When the processing plate 71 moves upward, the magnetic spring 73 is de-energized and extends, causing the scraper 76 to abut against the side wall of the scraper 56 and scrape the impurities scraped from the surface of the scraper 56 upward, thus avoiding affecting the scraping work of the scraper 56.

[0034] As the vertical rod 54 moves upward, the vertical rod 54 will use the piston 62 to squeeze the cleaning fluid inside the rectangular cylinder 61 through the second one-way tube 83 to spray it out to multiple adjacent nozzles 84, thereby wetting the bird droppings and other hard-to-clean impurities that the scraper 56 is in contact with, softening stubborn stains, and further improving cleaning efficiency.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
