Description

Technical Field

[0001] This invention relates to the field of solar energy-saving lamps, and more particularly to a solar energy-saving lamp with a self-cleaning function. Background Technology

[0002] Solar energy-saving lamps are an important solution for urban and rural public lighting and independent outdoor power supply. Their power generation efficiency directly affects the continuity and stability of the lighting system. When operating outdoors in complex environments for extended periods, dust, fallen leaves, and other pollutants easily accumulate on the surface of the solar panels, leading to decreased light transmittance and reduced power generation efficiency. Due to the dispersed installation locations and varying environmental conditions, the cleaning and maintenance of solar panels must balance efficient decontamination with low energy consumption.

[0003] Traditional solar energy-saving lamp cleaning methods generally suffer from low automation and reliance on external resources. The cleaning process typically requires manual intervention or electric drive, and often employs a single scraping method aligned with the direction of contaminant adhesion, making it difficult to effectively remove adhesive pollutants. Furthermore, cleaning systems often lack self-recovery capabilities, leaving contaminants behind on the edges of the panel and creating secondary blockages. Existing reset mechanisms often require additional energy input, increasing system energy consumption and structural complexity. In addition, the lack of adequate consideration for contaminant collection and treatment during the cleaning process may cause environmental pollution. Summary of the Invention

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] 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.

[0025] Example 1

[0026] As attached Figures 1 to 10The illustration shows a solar-powered energy-saving lamp with a self-cleaning function. A solar panel 1 is mounted at an angle on top of a supporting structure via an aluminum alloy frame. Its surface is covered with a tempered glass protective layer, and water-guiding grooves are provided around its perimeter. Heat dissipation fins are integrated on the back. The lamp body 2 is fixed below the solar panel 1 via universal connectors. Its internal modular design includes a light source module and a heat dissipation duct, and the outer shell is made of waterproof material. A battery 3 is installed in an independent sealed compartment at the bottom of the lamp body 2 and is connected to various electrical units via flame-retardant cables. A temperature monitoring element is installed inside the battery compartment. A controller 4 is integrated in the control room of the lamp body 2 and includes an intelligent control chip and an environmental sensing module. Status indicator lights are provided on its surface. When the ambient light intensity reaches a set threshold, the controller 4 automatically switches the lighting mode and precisely manages the voltage and current parameters during the charging process. Under sunlight, the solar panel 1 continuously converts light energy into DC power, which is then charged to the battery 3 through the charge / discharge management circuit of the controller 4. The battery 3 provides continuous power to the lighting system at night or on cloudy days.

[0027] The cleaning mechanism 5 is installed on the light-receiving surface of the solar panel 1. The track assembly 501 adopts a combined structure, including an upper track 504, a lower track 505, and multiple sets of connecting frames 506. The track cross-section is designed with an irregular structure. The cleaning assembly 502 includes a moving frame 507, a cleaning scraper 508, a counterweight 509, and a roller assembly 513. The roller assembly 513 consists of an upper roller 514 and a lower roller 515 forming a combined rolling system. The locking mechanism 503 adopts the lever braking principle and includes a brake lever 510, a friction plate 511, an adjusting component 512, a limiting protrusion 516, and a limiting groove 517. The moving frame 507 forms a rolling engagement with the track assembly 501 through the roller assembly 513. The upper roller 514 is embedded in the guide rail of the upper track 504, and the lower roller 515 is engaged in the sliding channel of the lower track 505. In the middle; when the moving frame 507 slides smoothly down the inclined track assembly 501 under the gravity of the counterweight 509, the upper roller 514 and the lower roller 515 rotate synchronously in the track, driving the cleaning scraper 508 to evenly scrape off the contaminants on the surface of the solar panel 1. At the same time, the side wall of the moving frame 507 pushes the brake rod 510 to rotate around the axis. The friction plate 511 and the contact surface of the moving frame 507 generate controllable frictional resistance. The limiting protrusion 516 slides in the arc track of the limiting groove 517 with the brake rod 510. When the limiting protrusion 516 contacts the end of the limiting groove 517, the brake rod 510 reaches the maximum rotation angle. The initial deflection angle of the brake rod 510 can be precisely adjusted by the rotating adjustment component 512 to change the braking torque. The connecting frame 506 ensures that the track system maintains structural integrity under dynamic load through multi-point fixation.

[0028] The flow guiding and collecting mechanism 6 is located at the drainage edge of the solar panel 1. The flow guiding plate 601 is integrally molded and includes an inclined part 603, a horizontal part 604, and a side baffle 605, with rounded corners at each connection. The collection box 602 adopts a split design and includes a box body 606, a filter part 607, and a discharge part 608. The box body 606 has multiple filter chambers inside. The upper end of the inclined part 603 is tightly connected to the lower edge of the solar panel 1 by a waterproof sealing strip. The horizontal part 604 extends horizontally outward to form a water collection platform. The side baffle 607... 5. The inclined part 603 is positioned at a specific angle on both sides of the horizontal part 604 to form a flow channel. When the sewage and debris generated during the cleaning operation flow down the surface of the solar panel 1, the inclined part 603 guides the mixed fluid to the horizontal part 604. The side baffle 605 effectively constrains the flow direction of the fluid to prevent splashing. After the fluid enters the box 606, it passes through the multi-layer filter media of the filter part 607 to achieve solid-liquid separation. The purified liquid is discharged in an orderly manner through the flow control device of the discharge part 608. The box 606 and the horizontal part 604 are connected by a plug-in connection to facilitate regular cleaning and maintenance.

[0029] The reset mechanism 7 employs a mechanical winch mechanism and includes a winch wheel 701, a pull rope 702, and a handle 703. The winch wheel 701 is fixed to the top support of the upper track 504 via a heavy-duty bearing seat. When the operator turns the handle 703 clockwise, the winch wheel 701 rotates synchronously and winds up the pull rope 702. The pull rope 702 pulls the moving frame 507, causing it to rise at a uniform speed along the track assembly 501, thereby achieving precise reset of the cleaning assembly 502. During this process, the cleaning scraper 508 automatically detaches from the working surface of the solar panel 1. The winch wheel 701 integrates a self-locking anti-reverse mechanism to ensure a safe and reliable lifting process.

[0030] The protective mechanism 8 adopts a fully enclosed protective design, including a protective cover 801, drainage holes 802, and support columns 803. The protective cover 801 adopts a streamlined curved surface design to completely cover the top of the track system. The support columns 803 are installed between the protective cover 801 and the support frame of the solar panel 1 through a precision threaded adjustment mechanism. When encountering severe weather, the protective cover 801 directs rainwater, snow, and dust to safe areas on both sides. Accumulated water is quickly drained through the evenly distributed drainage holes 802. The support columns 803 provide stable support and can be adjusted in height to adapt to different installation conditions. The edges of the protective cover 801 adopt a flanged structure to enhance the drainage effect. The entire protective system provides comprehensive protection for the track assembly 501 under special weather conditions.

[0031] Example 2

[0032] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 10 As shown below, see details: Furthermore, the track assembly 501 includes an upper track 504, a lower track 505, and a connecting frame 506. The upper track 504 is fixedly installed on the upper edge of the solar panel 1, and the lower track 505 is fixedly installed on the lower edge of the solar panel 1. The connecting frame 506 is disposed between the upper track 504 and the lower track 505. The connecting frame 506 is detachably connected to the upper track 504 and the lower track 505. Preferably, both ends of the connecting frame 506 are fixedly connected to the upper track 504 and the lower track 505 respectively by bolts.

[0033] The upper track 504 has a first guide groove inside, and the lower track 505 has a second guide groove inside. The first guide groove and the second guide groove are aligned with each other to form a continuous guide path. The connecting frame 506 is arranged longitudinally at intervals on the surface of the solar panel 1. The cross-section of the connecting frame 506 is I-shaped to enhance the structural strength. A heat dissipation gap is maintained between the upper track 504 and the edge of the solar panel 1.

[0034] Furthermore, the cleaning assembly 502 includes a movable frame 507, a cleaning scraper 508, and a counterweight 509. The movable frame 507 is slidably disposed between the upper track 504 and the lower track 505. The cleaning scraper 508 is installed at the bottom of the movable frame 507. When the movable frame 507 moves downward along the track assembly 501 under the action of gravity, the cleaning scraper 508 is in close contact with the surface of the solar panel 1 to scrape off dirt. When the moving frame 507 is lifted by the reset mechanism 7, the cleaning scraper 508 detaches from the surface of the solar panel 1. A counterweight 509 is fixedly installed on the upper part of the moving frame 507. Guide wheels are provided on both sides of the moving frame 507 to cooperate with the guide grooves of the track assembly 501. A collision-proof block is provided at the front end of the moving frame 507, and a connecting ring is provided at the rear end of the moving frame 507 for external connection. The cleaning scraper 508 is made of elastic material and has multiple scraping teeth. The counterweight 509 is fixed to the mounting base of the moving frame 507 by bolts. When the moving frame 507 moves downward along the track assembly 501, the cleaning scraper 508 scrapes away dirt by adhering closely to the surface of the solar panel 1. The counterweight 509 provides continuous downward power. The guide wheels roll in the guide groove to ensure smooth movement. The collision-proof block plays a buffering role at the end of the lower track 505. The connecting ring provides a connection point for subsequent lifting operations.

[0035] The locking mechanism 503 is provided on the track assembly 501.

[0036] Furthermore, the locking mechanism 503 includes a brake lever 510, a friction plate 511, and an adjusting member 512. The brake lever 510 is rotatably mounted on the connecting frame 506 via a hinge shaft. The friction plate 511 is fixedly mounted on the end of the brake lever 510 and maintains contact with the side of the moving frame 507. The adjusting member 512 is located at the middle position of the brake lever 510. When the moving frame 507 moves downward along the track assembly 501, its side contacts the brake lever 510 and pushes it to rotate around the hinge shaft, thereby causing the friction plate to... 511 is pressed against the surface of the movable frame 507. The rotation angle of the brake lever 510 can be changed by rotating the adjusting component 512, thereby adjusting the pressure between the friction plate 511 and the movable frame 507. The brake lever 510 adopts a lever structure design, the friction plate 511 is made of a high friction coefficient material, the adjusting component 512 adopts a threaded adjustment structure, the rotation range of the brake lever 510 is limited by the limiting block on the connecting frame 506, and the contact surface between the friction plate 511 and the movable frame 507 is set to be arc-shaped to increase the contact area.

[0037] Furthermore, the guide plate 601 includes an inclined portion 603, a horizontal portion 604, and a side baffle 605. The inclined portion 603 extends downward from the lower edge of the solar panel 1, the horizontal portion 604 is located at the end of the inclined portion 603, and the side baffles 605 are located on both sides of the horizontal portion 604. The inclined portion 603 and the horizontal portion 604 are connected by an arc transition, and the side baffles 605 are vertically fixed to the horizontal portion 604. The inclined portion 603 is configured as a flat plate structure to guide the water flow downward, the horizontal portion 604 is configured as a horizontal plate structure to collect and temporarily store the water flow, and the side baffles 605 are configured as vertical plates to prevent the water flow from overflowing laterally. As water flows down the surface of the solar panel 1, the inclined part 603 receives the water flow and guides it to the horizontal part 604. The horizontal part 604 carries the water flow and converges it towards the center. The side baffle 605 restricts the diffusion of the water flow to ensure directional flow. The inclined part 603 is fixed to the lower edge of the solar panel 1 by bolts. The horizontal part 604 and the inclined part 603 are manufactured by integral molding. The side baffle 605 and the horizontal part 604 are connected by welding to form an integral structure. The surface of the inclined part 603 is provided with multiple guide grooves to enhance the diversion effect. The bottom of the horizontal part 604 is provided with reinforcing ribs to improve the structural strength. The top of the side baffle 605 is provided with a flange to increase rigidity.

[0038] Furthermore, the collection box 602 includes a box body 606, a filter section 607, and a discharge section 608. The box body 606 is fixedly connected to the end of the horizontal section 604. The filter section 607 is detachably disposed inside the box body 606. The discharge section 608 is installed at the bottom of the box body 606. The box body 606 is configured as a container structure with an open top to receive water flow from the guide plate 601. The filter section 607 adopts a mesh filter structure to intercept solid debris. The discharge section 608 is provided with a control valve to regulate the drainage flow rate. When water flows from the horizontal section 604... When the water flows into the housing 606, the filter section 607 filters the water flow, and the discharge section 608 discharges the filtered water flow in a directional manner. The housing 606 and the horizontal section 604 are fixed by a snap-fit ​​connection. The filter section 607 is installed in the housing 606 by a slide rail structure for easy disassembly and cleaning. The discharge section 608 is connected to the housing 606 by a threaded connection. The housing 606 is provided with a flow guide baffle to extend the water flow path. The filter section 607 adopts a multi-layer filter screen structure to improve the filtration effect. The outlet of the discharge section 608 is provided with an anti-backflow device.

[0039] Furthermore, the reset mechanism 7 includes a winch 701, a pull rope 702, and a handle 703. The winch 701 is fixedly mounted on the top of the upper track 504 via a bearing seat. One end of the pull rope 702 is wound around the winch 701, and the other end is connected to the connecting ring of the moving frame 507. The handle 703 is fixedly mounted on the rotating shaft of the winch 701. When the handle 703 is rotated, the winch 701 rotates accordingly and winds the pull rope 702. The pull rope 702 pulls the moving frame 507 upward along the track assembly 501 to achieve reset. The surface of the winch 701 is provided with anti-slip grooves to increase the friction with the pull rope 702. The pull rope 702 is made of high-strength flexible material. The handle 703 is designed with a foldable structure to save space. The winch 701 has a ratchet mechanism inside to prevent reverse rotation. The pull rope 702 changes direction through a guide pulley to ensure smooth traction. When the moving frame 507 rises, the cleaning scraper 508 disengages from the surface of the solar panel 1.

[0040] Furthermore, the protective mechanism 8 includes a protective cover 801, a drainage hole 802, and a support column 803. The protective cover 801 is positioned above the track assembly 501, the drainage hole 802 is located at the bottom of the protective cover 801, and the support column 803 is positioned between the protective cover 801 and the solar panel 1. The protective cover 801 adopts an arc-shaped structure to guide rainwater to both sides. The drainage hole 802 is evenly distributed along the bottom edge of the protective cover 801 to quickly drain accumulated water. The support column 803 adopts an adjustable-height column structure to adapt to different installation angles. When rainwater falls on the surface of the protective cover 801, the water flow is diverted to both sides along the arc-shaped surface and discharged through the drainage hole 802. The support column 803 is fixed to the protective cover 801 and the solar panel 1 frame by a threaded connection. The edge of the protective cover 801 is provided with a downward-folded guide edge to enhance the drainage effect. The inner side of the drainage hole 802 is provided with an anti-clogging filter structure, and the bottom of the support column 803 is provided with an anti-slip pad to increase installation stability.

[0041] The protective cover 801 is located above the track assembly 501 and the cleaning assembly 502, and maintains a gap between them to ensure that the movement of the cleaning assembly 502 is not interfered with.

[0042] Furthermore, the movable frame 507 is equipped with a roller assembly 513, which includes an upper roller 514 that rolls with the upper rail 504 and a lower roller 515 that rolls with the lower rail 505. The upper roller 514 is mounted on both sides of the upper part of the movable frame 507 via shafts, and the lower roller 515 is mounted on both sides of the lower part of the movable frame 507 via shafts. The outer edge of the upper roller 514 is set in a groove shape to fit into the guide rail of the upper rail 504, and the outer edge of the lower roller 515 is set in a flange structure to engage with the groove of the lower rail 505. When the movable frame 507 moves along the rail assembly 501, the upper roller 514 rolls in the upper rail 504, and the lower roller 515 rolls synchronously in the lower rail 505. The contact surface between the upper roller 514 and the upper rail 504 forms the main load-bearing area, and the lower roller 515 rolls in the lower rail 505. The mating surface between wheel 515 and lower track 505 provides lateral stability. During the movement of the moving frame 507, the roller assembly 513 rotates continuously to reduce frictional resistance. The installation positions of the upper roller 514 and lower roller 515 are kept in the same vertical plane to ensure balanced movement. The roller assembly 513 is connected to the shaft through bearings to achieve smooth rotation. The side plate of the moving frame 507 has mounting holes for fixing the roller shaft. The outer edge of the roller is made of wear-resistant material to extend its service life. The diameters of the upper roller 514 and lower roller 515 are designed to match the track size. The rolling stroke of the roller assembly 513 in the track is consistent with the working range of the cleaning scraper 508. When the moving frame 507 is subjected to gravity, the roller assembly 513 converts sliding friction into rolling friction, thereby reducing movement resistance.

[0043] Furthermore, the brake lever 510 is provided with a limiting protrusion 516, and the connecting frame 506 is provided with a limiting groove 517. The limiting protrusion 516 and the limiting groove 517 cooperate to limit the rotation angle of the brake lever 510. The limiting protrusion 516 is fixed to the side or end of the brake lever 510, and the limiting groove 517 is opened at the corresponding position of the connecting frame 506. The limiting groove 517 is set with an arc-shaped structure to match the rotation trajectory of the brake lever 510. When the brake lever 510 rotates around the hinge point... When in motion, the limiting protrusion 516 slides inside the limiting groove 517. When the limiting protrusion 516 contacts the end of the limiting groove 517, the rotation of the brake lever 510 is stopped, thereby preventing excessive rotation. The end of the limiting groove 517 is set as a baffle structure to provide a hard stop. An appropriate gap is maintained between the limiting protrusion 516 and the limiting groove 517 to ensure smooth sliding. When the brake lever 510 rotates, the angle is controlled by the interaction between the limiting protrusion 516 and the limiting groove 517.
