Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic equipment technology, and in particular relates to the operation and maintenance of photovoltaic panels, specifically a prefabricated photovoltaic panel cleaning robot replacement vehicle. Background Technology

[0002] As one of the main tools for intelligent operation and maintenance, photovoltaic cleaning robots can not only solve a series of problems existing in traditional manual cleaning, but also have good returns on investment and effectively promote the de-manualization of power plant operation and maintenance.

[0003] A typical photovoltaic panel cleaning robot consists of two main components: the cleaning robot and the transfer vehicle. After cleaning one row of photovoltaic panels, the cleaning robot needs to be moved to the next row of photovoltaic panels by the transfer vehicle to continue cleaning.

[0004] The line-changing vehicle is also a type of unattended intelligent robot. For safety and reliability reasons, most manufacturers make the line-changing vehicle into an integral welded structure, which makes the handling and installation of the line-changing vehicle very inconvenient and also increases the production cost of enterprises.

[0005] With the gradual popularization of prefabricated buildings in my country, it is necessary to transfer prefabricated building technology to the operation and maintenance industry of new energy photovoltaic panels. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, this utility model provides a modular photovoltaic panel cleaning robot replacement vehicle, which effectively reduces the cost of handling and long-distance transportation.

[0007] The technical solution adopted by this utility model to solve the above problems is as follows: A modular photovoltaic panel cleaning robot includes an upper guide rail frame and a lower walking frame. The upper guide rail frame and the lower walking frame are foldable. Multiple columns are installed between the upper guide rail frame and the lower walking frame. Multiple walking wheels are installed on the front and rear sides of the lower walking frame. End face baffles are fixedly connected to the two ends of the walking wheel on one side. The walking wheel and the end face baffles form a guide groove wheel. One of the pillars is equipped with a vehicle anti-tipping device.

[0008] Preferably, the diameter of the end face baffle is larger than the diameter of the traveling wheel, and the guide groove wheel formed by the traveling wheel and the end face baffle is located on the same side of the lower traveling frame, forming a single-sided guide structure; a universal drive shaft is fixedly connected between the corresponding traveling wheels at the front and rear ends, and the universal drive shaft is rotatably connected to the lower traveling frame respectively.

[0009] Preferably, the upper guide rail frame is composed of multiple upper tubes, and the lower traveling frame is composed of multiple lower tubes. Adjacent upper tubes and adjacent lower tubes are fixedly connected with folding hinges that can be opened and closed. The hinge center of the folding hinge is higher than the upper end plane of the upper and lower tubes connected to it, so that adjacent upper tubes or lower tubes can be parallel to each other after being folded by the folding hinge, achieving a fully folded state.

[0010] Preferably, each end of the column is connected to a U-shaped fixing plate, and the other end of the U-shaped fixing plate is connected to the corresponding upper pipe and lower pipe respectively.

[0011] Preferably, the U-shaped fixing plate has multiple vertically arranged elongated holes on its central surface, and multiple round holes are respectively formed on the surface of the U-shaped fixing plate on both sides of the elongated holes; the U-shaped fixing plate is sleeved on the surface of the upper tube and the lower tube, and the U-shaped fixing plate is fixedly connected to the corresponding column by multiple sets of bolt and nut connectors.

[0012] Preferably, the plurality of circular holes are respectively inclined inward.

[0013] Preferably, turnbuckles and steel cables are fixedly connected to the surfaces of the two diagonally opposite U-shaped fixing plates, with the turnbuckles fixedly connected to the corresponding steel cables.

[0014] Preferably, the anti-tipping device for the vehicle includes a connecting plate and U-bolts. The surface of the connecting plate is provided with multiple key holes, and the U-bolts pass through the key holes respectively. The other end of the U-bolts is threadedly connected to the nuts respectively, so that the connecting plate is fixedly installed on the surface of the column. A guide groove plate with an opening at the bottom is fixedly connected between two adjacent columns. A guide roller is rotatably connected to the upper end of one of the connecting plates. The guide roller is located inside the guide groove plate. Inclined plates that tilt outward are fixedly connected to the openings at both ends of the guide groove plate.

[0015] This utility model has a novel structure, ingenious design, and is simple and convenient to operate. Compared with the prior art, it has the following advantages: Both the upper guide rail frame and the lower traveling frame are folding structures. During long-distance transportation, the upper guide rail frame and the lower traveling frame can be folded using folding hinges, which shortens the overall length of the upper guide rail frame and the lower traveling frame, making it convenient for loading and transportation. During on-site installation, the upper guide rail frame and the lower traveling frame can be unfolded using folding hinges. The guide groove wheel formed by the traveling wheel and the end face baffle is located on the same side of the lower traveling frame, forming a single-sided guide structure. The guide groove formed between the two end face baffles with larger diameters cooperates with the guide rail of the switching car to ensure that the switching car always travels along one side of the guide rail, preventing the switching car from derailing. Under the action of the switching car anti-tipping device, the stability of the switching car is enhanced, and the instability and tipping of a single switching car are prevented in strong winds. Two U-shaped fixing plates at opposite corners are respectively fixedly connected with turnbuckles and steel cables. By rotating the turnbuckles, the tension of the steel cables can be strengthened, improving the stability of the connection between the upper pipe, the lower pipe and the column, thereby enhancing the overall mechanism of the switching vehicle.

Detailed Implementation

[0028] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figure 1-11 As shown, a modular photovoltaic panel cleaning robot switching vehicle travels on the upper end of a guide rail and includes an upper guide rail frame and a lower traveling frame. The upper guide rail frame and the lower traveling frame are foldable. Since both the upper guide rail frame and the lower traveling frame are foldable structures, during long-distance transportation, the upper guide rail frame and the lower traveling frame can be folded using folding hinges, which shortens the overall length of the upper guide rail frame and the lower traveling frame, making it convenient for loading and transportation. During on-site installation, the upper guide rail frame and the lower traveling frame are unfolded using folding hinge 1. Multiple uprights 8 are installed between the upper guide rail frame and the lower traveling frame, connecting them to enhance the overall stability of the trolley. Multiple traveling wheels 4 are installed on the front and rear sides of the lower traveling frame, located at the upper end of the guide rail and engaging with it. A universal drive shaft is fixedly connected between corresponding traveling wheels 4 at both ends, rotatably connecting to the lower traveling frame to facilitate the trolley's movement on the guide rail surface. Furthermore, end face baffles 14 are fixedly connected to both ends of one traveling wheel 4, allowing for... The traveling wheel 4 and the end face baffle 14 form a guide groove wheel 5, which is used to cooperate with the guide rail of the switching vehicle. The diameter of the end face baffle 14 is larger than the diameter of the traveling wheel 4. The guide groove wheel 5 formed by the traveling wheel 4 and the end face baffle 14 is located on the same side of the lower traveling frame, forming a single-sided guide structure. The guide groove formed between the two end face baffles 14 with larger diameters cooperates with the guide rail of the switching vehicle, ensuring that the switching vehicle always travels along one side of the guide rail and will not cause the switching vehicle to derail. A switching vehicle anti-tipping device is installed on the surface of the column 8 on one side. The switching vehicle anti-tipping device is used to connect with the cleaning component of the photovoltaic panel to enhance the stability of the switching vehicle and prevent a single switching vehicle from being unstable and tipping over in windy weather.

[0030] The upper guide frame is composed of multiple upper tubes 7, and the lower traveling frame is composed of multiple lower tubes 3. Adjacent upper tubes 7 and adjacent lower tubes 3 are fixedly connected by folding hinges that can be opened and closed. The hinge center of the folding hinge is higher than the upper end plane of the upper tube 7 and lower tube 3 connected to it, so that adjacent upper tubes 7 or lower tubes 3 can be parallel to each other after being folded by the folding hinge, achieving a fully folded state, which facilitates the folding and unfolding of the upper guide frame and the lower traveling frame. The folding hinge includes two legs with holes on the surface, a connecting bolt 22, and a connecting nut 21. The two ends of the legs are fixedly connected to two corresponding upper tubes 7 or two corresponding lower tubes 3, respectively. The other end of the connecting bolt 22 passes through the hole at the inner end of the two legs, and the other end of the connecting bolt 22 is threadedly connected to the connecting bolt 22, realizing the connection of the two legs and forming a folding hinge structure, so that the upper tubes 7 or lower tubes 3 connected by the folding hinge can be folded.

[0031] The column 8 has U-shaped fixing plates 2 connected to both ends, and the other end of the U-shaped fixing plates 2 is connected to the corresponding upper tube 7 and lower tube 3. The U-shaped fixing plates 2 provide a stable connection between the upper tube 7 and lower tube 3 via the column 8, thereby improving the installation stability of the upper guide rail frame and the lower traveling frame and facilitating installation. Furthermore, the center surface of the U-shaped fixing plates 2 has multiple vertically arranged elongated holes, and the surfaces of the U-shaped fixing plates 2 on both sides of the elongated holes have multiple round holes. One end of the U-shaped fixing plates 2 has an opening, through which the U-shaped fixing plates 2 are fitted onto the upper tube 7 and lower tube 3. On the surface of pipe 3, the U-shaped fixing plate 2 and the corresponding column 8 are fixedly connected by multiple sets of bolt and nut connectors. The bolt and nut connectors include fixing bolts and nuts that cooperate with the fixing bolts. When connecting, the two ends of the column 8 are inserted into the inside of the U-shaped fixing plate 2, the fixing bolts are inserted into the round holes on both sides, and fixed by nuts. The fixing bolts on both sides limit the column 8 and prevent the column 8 from tilting. The inside of the elongated hole is threaded with a fixing bolt. By rotating the fixing bolt, the pressure of the fixing bolt on the column 8 can be increased under the action of the threaded connection, thereby achieving the effect of fixing the column 8.

[0032] Furthermore, such as Figure 3As shown, the multiple circular holes are inclined inwards respectively. When the limiting bolts 10 are inserted into different circular holes, the spacing and height of the two limiting bolts 10 can be adjusted. This allows for adjustment based on the width of the upper tube 7, lower tube 3, and column 8. Furthermore, to improve the stability of the connection between the upper tube 7, lower tube 3, and column 8, turnbuckles 11 and steel cables 12 are fixedly connected to the surfaces of the two diagonally opposite U-shaped fixing plates 2. The turnbuckles 11 are fixedly connected to the corresponding steel cables 12. By rotating the turnbuckles, the tension of the steel cables 12 can be strengthened, improving the stability of the connection between the upper tube 7, lower tube 3, and column 8, thereby enhancing the overall mechanism of the switching vehicle.

[0033] Furthermore, to improve the stability of the switching trolley during use, the switching trolley anti-tipping device includes a connecting plate 6 and U-bolts 18. The surface of the connecting plate 6 has multiple keyholes 19, through which the U-bolts 18 pass, so that the connecting plate 6 and the U-bolts 18 are located on opposite sides of the column 8. The other end of the U-bolts 18 is threadedly connected to a nut, thus fixing the connecting plate 6 to the surface of the column 8. Figure 11 As shown, during installation, two adjacent connecting plates 6 are arranged alternately, one above the other. A guide groove plate 17 with an open bottom is fixedly connected between two adjacent columns 8. Guide rollers 15 are rotatably connected to the upper end of one of the connecting plates 6, and roller shafts 16 are rotatably connected to the lower ends of the guide rollers 15. The roller shafts 16 are fixedly connected to the corresponding lower connecting plate 6. The guide rollers 15 are located inside the guide groove plate 17. When connecting the trolley and the photovoltaic panel cleaning assembly via the trolley anti-tipping device, the columns of the trolley and the photovoltaic panel cleaning assembly can be connected using the trolley anti-tipping device. The guide rollers 15 can be first... One end of the trough plate 17 is fixedly connected to the corresponding column 8. Then, the guide roller 15 is inserted between the guide trough plates 17, and the two adjacent columns 8 are connected by the guide roller 15. The two ends of the guide trough plate 17 are respectively fixedly connected with outward inclined plates 20, which are used to guide the guide roller 15 when it is connected to the guide trough plate 17, so that the guide roller 15 can enter the inner side of the guide trough plate 17 under the guidance of the inclined groove, and realize the connection between the switching vehicle and the cleaning component of the photovoltaic panel. With the connection of the guide roller 15 and the guide trough plate 17, a whole is formed, thereby significantly improving the stability of the switching vehicle when facing strong winds and other severe weather.
