Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cleaning technology, and in particular to a waterless cleaning robot for the surface of photovoltaic panels used on highways. Background Technology

[0002] With the rapid development of renewable energy, photovoltaic power generation is being increasingly widely applied along highways, especially with large-scale installations of photovoltaic modules on highway slopes, sound barriers, and service area rooftops. This not only achieves the multi-functional use of land resources but also provides strong support for the low-carbonization of transportation energy. However, the clean maintenance of photovoltaic modules has gradually become one of the key factors restricting their long-term stable power generation efficiency.

[0003] In complex environments such as highways, windblown sand, dust, exhaust particles, and plant and animal residues easily accumulate on the surface of photovoltaic panels, causing shading of sunlight and affecting photoelectric conversion efficiency. Actual measurements show that surface dust accumulation can cause a 5% to 30% loss in power generation efficiency. Traditional cleaning methods rely on manual labor and water resources, which are not only inefficient but also pose problems such as traffic disruption and water scarcity, making implementation difficult.

[0004] Currently, most automated photovoltaic (PV) cleaning equipment on the market is designed for centralized power stations on flat land, lacking adaptability to operate in the narrow and complex terrain of highways. Furthermore, it generally relies on water washing methods, which does not meet the requirements for water conservation and automated operation and maintenance. Therefore, there is an urgent need for an intelligent cleaning robot suitable for highway PV arrays, possessing high environmental adaptability and waterless cleaning capabilities, to improve the overall operating efficiency and intelligent maintenance level of PV systems. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a waterless cleaning robot for the surface of photovoltaic panels used in highways.

[0006] A waterless cleaning robot for photovoltaic panels used on highways, comprising a moving mechanism, a cleaning mechanism, and a control system, characterized in that:

[0007] The moving mechanism adopts a steel cable traction structure, including corrosion-resistant guide steel cables erected at the beginning and end of the photovoltaic array, a drive motor, a tensioning device, and a travel limit structure; the bottom of the equipment is equipped with directional guide wheels and limit guide rails;

[0008] The cleaning mechanism integrates a roller brush, a bristle brush, and a silicone scraper in sequence along the direction of travel to form a three-stage dry cleaning unit.

[0009] The roller brush is driven by a gear transmission system, which includes a large gear linked to the rubber wheel and a meshing small gear, with a speed ratio of 1:5.

[0010] The cleaning units are arranged in two groups symmetrically along the central axis of the equipment and are fixedly connected by a square tube frame.

[0011] Furthermore, in order to better realize this utility model, the roller brush is a roller structure with medium hardness and a pressure limiting design on the surface; the brush is made of flexible nylon or modified fiber bristles.

[0012] Furthermore, in order to better realize this utility model, the gear transmission system includes a guide rod and a vertical bearing seat. The large gear is connected to the rubber wheel through the guide rod, and the small gear drives the roller brush to rotate at high speed through the guide rod.

[0013] Furthermore, in order to better realize this utility model, the mobile mechanism supports single-line single-cleaning and reciprocating bidirectional cleaning modes, and the control system can adjust the moving speed and return path.

[0014] Furthermore, in order to better realize this utility model, the directional guide wheel and the limiting guide rail are adapted to the inclined slope surface to ensure that the equipment moves stably on a non-horizontal surface.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention utilizes a three-stage dry cleaning chain consisting of roller brushes, bristle brushes, and scrapers to achieve efficient removal of dust, sand, and mud in waterless conditions, making it suitable for water-scarce environments such as highways. A steel cable traction structure, combined with directional guide wheels and limiting rails, ensures stable operation of the equipment on sloping slopes and narrow photovoltaic arrays, overcoming the terrain limitations of traditional equipment. A 1:5 gear ratio design allows the roller brushes to rotate at high speeds during low-speed movement, significantly enhancing cleaning power while reducing overall energy consumption. The symmetrical layout of the dual cleaning units achieves comprehensive coverage, increasing the cleaning rate per operation. It supports a reciprocating bidirectional cleaning mode, reducing idle return time, improving maintenance efficiency, and its modular structure facilitates component replacement and maintenance.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] Figures 1-7 This is a specific embodiment of the present invention, which is a waterless cleaning robot for photovoltaic panels on highways. This robot integrates a multi-stage dry cleaning mechanism including roller brushes, bristle brushes, and scrapers to achieve efficient, low-energy, and waterless automatic cleaning of the photovoltaic module surface, solving the problems of cleaning difficulties, high energy consumption, low efficiency, and water resource dependence in existing technologies for highway scenarios. It includes:

[0029] I. Movement Mode and Running Path Control

[0030] This invention employs a cable-driven mobile structure. The mobile structure uses fixed stopping positions at the beginning and end of the photovoltaic array, along with corrosion-resistant, high-tensile guide cables, to pull the cleaning equipment in a reciprocating linear motion along the longitudinal path of the photovoltaic modules.

[0031] 1. Tensioning devices and travel limit structures are installed at both ends of the steel cable to ensure stable operation and adjustable traction tension of the cleaning equipment; 2. The bottom of the equipment is equipped with directional guide wheels and limit guide rails to ensure stable movement on non-horizontal surfaces such as sloping slopes; 3. The moving speed can be controlled by the built-in motor to achieve uniform speed operation or a slow-moving control mode while cleaning; 4. It can support single-line single-cleaning and reciprocating bidirectional cleaning modes to reduce the return empty load rate and improve work efficiency.

[0032] II. Multi-stage dry cleaning mechanism and coordinated cleaning process

[0033] Along the direction of the equipment's movement, three waterless cleaning modules—roller brushes, bristle brushes, and scrapers—are arranged in sequence to form an integrated dry cleaning chain that "loosens at the front, sweeps in the middle, and cleans at the back."

[0034] 1. Roller brush

[0035] Installed at the front of the equipment, the roller brush rotates via gear linkage, rolling against the surface of the photovoltaic panel to quickly loosen loose dust particles and sand, providing the first stage of coarse cleaning. The roller brush is made of a material with moderate hardness, and combined with a pressure-limiting design, it avoids scratching or indenting the photovoltaic panel.

[0036] 2. Brush

[0037] Installed after the roller brush, the bristles are made of flexible nylon or modified fibers, providing excellent elasticity and dust-removing properties. During movement, the brush effectively removes firmly adhering dust and fine particles from the panel surface while protecting the component surface from damage.

[0038] 3. Scraper

[0039] Located at the end of the brush, a silicone scraper adheres to the component surface to perform a final removal of residual dust, dirt, or damp particles. This device ensures that particles not removed during the brushing process do not remain on the component surface, thereby improving the final cleanliness.

[0040] The three sections above work together through mechanical linkage, and the cleaning path covers the entire width of the photovoltaic panel in a single operation, ensuring a thorough cleaning effect without any blind spots.

[0041] The movement of the drive device is achieved by a steel cable, which causes the rubber wheel 3 to roll on the surface 1 of the photovoltaic panel. The rubber wheel 3 is connected to the large gear 4 via a guide rod 11. The rolling of the rubber wheel 3 drives the large gear 4 to rotate, forming a meshing transmission structure between the large gear 4 and the small gear 5. The speed ratio between the two gears is 1:5, enabling the small gear 5 to rotate at high speed. The small gear 5 is linked to the roller brush 2 via the guide rod 11 to drive the roller brush 2. Through the meshing transmission structure of the large and small gears, the small gear 5 can drive the connected roller brush 2 to operate at high speed, thus achieving efficient cleaning of the photovoltaic panel surface 1 by the roller brush 2 during the low-speed gliding process of the cleaning device. The guide rod 11 is fixed to the square tube 6 structure of the device frame via a vertical bearing seat 10. The roller brush 2 is used to remove loose dust particles and sand adhering to the panel surface.

[0042] As the moving mechanism moves the device along the panel, the brush 7, located after the roller brush 2, peels off and cleans the dust and fine particles with strong adhesion during the movement, further improving the cleaning effect. A scraper 8 is located after the brush 7. When the equipment moves, the scraper 8 will gently scrape the surface of the photovoltaic panel to remove mud or damp particles for secondary cleaning, ensuring cleanliness.

[0043] The roller brush 2, the brush 7, and the scraper 8 constitute a cleaning unit. The cleaning unit has two symmetrically distributed cleaning structures with the central axis of the device as the center of symmetry. The other cleaning unit is used to perform final cleaning of residual dust to further improve the overall cleaning efficiency.

[0044] The brush 7, scraper 8 and vertical bearing seat 10 are all fixedly connected to the square tube 6 by bolts 9 and nuts 12, which makes the structure stable and easy to maintain and replace.

[0045] After the cleaning task is completed or the device reaches the end of the cleaning path, the device reverses the path through the control system and returns to the initial stopping position.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
