Description

Technical Field

[0001] The utility model relates to the field of automatic solar panel cleaning robots, in particular to an automatic solar panel cleaning robot. Background Art

[0002] Solar energy is currently recognized as one of the clean energy sources. There are relatively few restrictions on the acquisition of solar energy. In any place on the earth with sufficient sunlight, electrical energy can be converted and used through the corresponding solar energy collection, conversion and storage devices.

[0003] Solar panels are commonly used to collect and convert solar energy into electrical energy. People only need to place small square panels on roofs, outdoors or on relatively wide fields. Solar panels convert and store energy through corresponding light-absorbing and heat-absorbing materials when sunlight shines on their surfaces. After long-term use, the surface of solar panels installed outdoors will be covered with a layer of dust, which hinders the normal use of solar panels and greatly reduces the working efficiency of solar panels. Therefore, the surface of solar panels needs to be cleaned and dusted regularly.

[0004] Generally, the surface of solar panels is cleaned and dusted by manually pulling out a water pipe and waving a high-pressure nozzle to strongly flush the solar panels. This uses a large amount of water to spray high-pressure water through the high-pressure nozzle, which causes a waste of water resources to a certain extent. Manual flushing is relatively physically demanding, and some positions on the solar panels cannot be effectively cleaned. In addition, after a large-scale flushing and spraying with a handheld water gun, a large amount of water will flow on the ground. In some places, the overflowing sewage may have some negative impacts on hygiene, environment, and construction. Therefore, a robot device specifically for automatic cleaning of solar panels is needed. Utility Model Content

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] Embodiment 1

[0028] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 5In order to solve the above technical problems, the technical solution provided by the utility model is: a solar panel automatic cleaning robot, comprising a base 1, a plurality of universal wheels 2 are connected to the bottom of the base 1 to facilitate the movement of the robot device on the ground, a water tank 18 is connected to the top of the base 1, a water inlet 19 is connected to the top of the water tank 18 for replenishing water in the water tank 18, a plugging cover 20 matching the water inlet 19 is connected to the top of the water tank 18 for switching the water inlet 19 of the water tank 18, a water pipe 15 is connected to the water pipe 15, a No. 1 water pump 16 is connected to the water in the water tank 18 to transport the water in the water tank 18 to the water collecting box 13 through a telescopic hose 17 and the water pipe 15, and a plurality of spray holes 14 matching the water pipe 15 are connected to one side above the base 1.

[0029] Clean water is delivered to the water collecting box 13 through the water tank 18 via the water pipe 15 and the telescopic hose 17, and is sprayed out from the small spray holes 14 on the bottom of the water collecting box 13 under the action of the water delivery pressure of the first water pump 16, thereby washing the solar panel.

[0030] Embodiment 2

[0031] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 A guide rail 3 is connected to one side above the base 1, and support rods 4 and hydraulic push rods 5 are rotatably connected between the two ends of the guide rail 3 and the base 1 respectively. A threaded shaft 7 is rotatably connected inside the guide rail 3, and a No. 1 motor 6 matched with the threaded shaft 7 is connected inside one end of the guide rail 3 to provide power for the rotation of the threaded shaft 7. A bracket 8 is connected to one side above the base 1, and a connecting block 9 with an internal thread structure and matched with the threaded shaft 7 is connected at one end of the bracket 8.

[0032] By extending and retracting the hydraulic push rod 5 which rotates relative to the base 1 and the guide rail 3, and under the mutual rotation limiting action of the guide rail 3 and the support rod 4, the guide rail 3 can be raised on the base 1 and adjusted to rotate to different angles, so that the solar panels set at different inclination angles can be brushed and processed. The threaded shaft 7 cooperates with the connecting block 9 at one end of the bracket 8, and under the limiting action of the contact point between the guide rail 3 and the bracket 8, the bracket 8 follows the rotation of the threaded shaft 7 and moves to various positions on the guide rail 3.

[0033] Embodiment 3

[0034] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 4A transmission shaft 11 is rotatably connected in the bracket 8, and a No. 2 motor 10 matched with the transmission shaft 11 is connected in one side of the bracket 8 to provide power for the rotation of the transmission shaft 11. A roller brush 12 is connected to the transmission shaft 11. The bracket 8 is located on both sides of the roller brush 12 and is connected to a water collecting box 13 connected to the end of the water pipe 15 away from the water tank 18. The spray hole 14 is arranged at the bottom of the water collecting box 13, and a telescopic hose 17 is commonly connected between the water pipe 15 and the water tank 18.

[0035] By rotating the transmission shaft 11, the roller brush 12 rotates at high speed on the solar panel, thereby brushing the solar panel. The water collecting box 13 with the spray hole 14, located at the front end of the roller brush 12, can spray water on the solar panel, and located at the rear end, can flush the brushed part of the solar panel. The water washing and brushing are combined to clean the solar panel more effectively.

[0036] Embodiment 4

[0037] Combined with Figure 1 , Attachment Figure 2 The base 1 is connected to one end of the support rod 4 with a water tank 21 that matches the water collecting box 13 and the roller brush 12. A connecting frame 22 is commonly connected between the water tank 21 and the base 1 for supporting and fixing the water tank 21. The base 1 is located on one side of the water tank 18 and is connected to a collecting tank 24. A drain port 25 is connected to one side of the bottom of the collecting tank 24 for discharging waste water from the collecting tank 24. A valve 26 is connected to the drain port 25 for controlling the switch of the drain port 25. A drain pipe 23 is commonly connected between the bottom end of the water tank 21 and one side of the collecting tank 24. A No. 2 water pump 27 is connected to the drain pipe 23 for quickly discharging water in the water tank 21 through the drain pipe 23 to the collecting tank 24 for temporary storage.

[0038] By providing a relatively low water tank 21, which is located below the lower end of the solar panel when in use, the sewage flowing down from the solar panel during cleaning can be collected, and the sewage can be collected into a collection tank 24 for temporary storage along the drainage pipe 23 at the bottom.

[0039] During the specific implementation of the utility model, when the automatic cleaning robot device is used to clean the solar panel, the device is pushed to one side of the solar panel, and the guide rail 3 and the bracket 8 with the brushing mechanism are lifted to an inclination angle matching the solar panel through the hydraulic push rod 5 connected between the guide rail 3 and the base 1, and the robot device is pushed close to the solar panel. A universal wheel 2 structure is provided below the device for easy movement. If automation is also desired in this part, a corresponding mobile control device can be used instead. This function is not critical to the key points that the present application focuses on improving, so it will not be described or discussed in detail. During cleaning, after the No. 1 water pump 16 is started, the clean water stored in the water tank 18 is pumped out through the water pipe 15 and transported to the water collecting box 13. Under the pressure given by the No. 1 water pump 16, the clean water is sprayed onto the solar panel from the various spray holes 14 at the bottom of the water collecting box 13. At the same time, the roller brush 12 in the bracket 8 is also in a state of rapid rotation. The solar panels are in contact with each other so that the surface of the solar panels is scrubbed clean. The scrubbing mechanism in the bracket 8 moves on the solar panels as the threaded shaft 7 in the guide rail 3 rotates. The cleaning order is as far as possible from the upper end to the lower end. When the scrubbing mechanism moves from one end of the solar panel to the other end, the cleaning is completed. During the cleaning, the water sprayed due to the scrubbing needs to flow toward the lower end along the surface of the solar panel. A water tank 21 below the bottom end can catch the flowing water to prevent the sewage from flowing to the ground and overflowing and causing unnecessary damage to the site sanitation. The waste water collected in the water tank 21 will be discharged into the collection tank 24 along the drain pipe 23. The No. 2 water pump 27 on the drain pipe 23 can accelerate the drainage speed of the drain pipe 23. When the water volume in the water tank 18 is low, or the sewage stored in the collection tank 24 needs to be discharged, the plug cover 20 and the valve 26 can be opened to open the water inlet 19 and the drain outlet 25, and the corresponding water replenishment or waste discharge operations can be performed.

[0040] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
