[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] To resolve the above issues, please refer to [link / reference]. Figures 1 to 5This utility model provides a photovoltaic panel cleaning trolley with a hoisting structure, including a cleaning trolley body 1, a hoisting assembly 2, and a controller 3. A water tank 4 is provided on the upper surface of the cleaning trolley body 1, and cleaning heads 5 are provided at opposite ends of the cleaning trolley body 1. The hoisting assembly 2 is disposed on the upper surface of the water tank 4, and includes a mounting base 21, a limiting member 22, and a hammer 23. The mounting base 21 is mounted on the surface of the water tank 4, and a tapered connecting groove 211 with a gradually decreasing diameter is formed in its middle, extending from one end of the mounting base 21 towards the end connected to the water tank 4. A through groove 212 is formed in the groove wall of the tapered connecting groove 211. The movable end of the limiting member 22 moves along the length direction of the through groove 212, protruding from the groove wall of the tapered connecting groove 211 during use and engaging with the periphery of the hammer 23. One end of the hammer 23 is connected to a drone, and the other end abuts against the mounting base 21. The mounting base 21 is connected to one end of the water tank 4 and has a water inlet 213. The middle part of the hammer 23 has a water inlet channel 231 corresponding to the water inlet 213 and the water inlet channel 231 is connected to the water tank 4. The controller 3 is electrically connected to the limiting member 22 and is used to control the separation of the limiting member 22 from the hammer 23.

[0033] Among them, such as Figure 2 As shown, the pendulum 23 has an annular groove 232 on its periphery corresponding to the limiting member 22. A connector 233 is located at the end of the pendulum 23 furthest from the water tank 4, connecting to the water injection channel 231. Hanging rings 234 are located on both sides of the connector 233, which are connected to a steel wire rope and then attached to a drone. The drone's direction of movement is controlled by a handheld remote control. A controller 3 is located on the periphery of the water tank 4 and includes a signal receiving module. When a worker uses the remote control to move the cleaning cart to the photovoltaic panel cleaning area or from the cleaning area to the ground, the signal receiving module and controller 3 control the limiting member 22 to move along the through groove 212. The end of the limiting member 22 disengages from the annular groove 232 of the pendulum 23, at which point the pendulum 23 separates from the mounting base 21, completing quick disassembly. Furthermore, when it is necessary to fill the water tank 4 during operation, the position of the mounting base 21 is identified by the camera of the drone so that the hammer 23 can be connected to the mounting base 21. After the hammer 23 is connected to the mounting base 21, the water loaded by the drone enters the water tank 4 through the pipe, the water filling channel 231 and the water filling port 213.

[0034] Furthermore, the main body 1 of the cleaning vehicle also includes components such as a GPS module, power supply, camera, and walking structure. The cleaning vehicle works with these modules to clean the photovoltaic panels quickly and accurately.

[0035] In optional embodiments, such as Figure 3 and Figure 5 As shown, the limiting member 22 includes a pin 221, a connecting rod 222, and a motor 223. The motor 223 is electrically connected to the controller 3. One end of the connecting rod 222 is hinged to the drive end of the motor 223, and the other end is hinged to the pin 221. The other end of the pin 221 passes through the tapered connecting groove 211. The motor 223 is connected to the connecting ear 214 disposed on the periphery of the mounting base 21 via a first connecting plate 6. The connecting ear 214 corresponds to the through groove 212. The first connecting plate 6 has a limiting hole. The motor 223 is installed in the limiting hole and connected to the first connecting plate 6 via limiting plates on both sides of the motor 223. The connecting ear 214 has a hollow structure and communicates with the through groove 212. The shape of the through groove 212 is the same as that of the pin 221, which can limit the movement direction of the pin 221. Furthermore, the connecting rod 222 includes two connected rods. One end of the two connected rods is hinged to the drive end of the motor 223, and the other end is hinged to the pin 221. When the cleaning trolley needs to be hoisted to the photovoltaic panel cleaning area at a high position, before the worker puts the hammer 23 into the mounting base 21, the worker controls the motor 223 to rotate counterclockwise via remote control, which drives the pin 221 to move and retract into the through slot 212. After the hammer 23 is put into the conical connecting slot 211, the worker controls the motor 223 to rotate in reverse again, and the pin 221 moves and engages with the annular slot 232 of the hammer 23, realizing a quick and stable connection between the two. When it is necessary to separate the mounting base 21 and the hammer 23, the worker sends a command to the controller 3 from the ground to make the motor 223 rotate. Under the action of the motor 223 and the connecting rod 222, the pin 221 moves away from the hammer 23 and its end is in the through slot 212, thereby realizing a quick separation between the two. In this embodiment, the pin 221 is equipped with a Hall sensor, and the annular groove of the hammer 23 is equipped with an annular magnet electrically connected to the controller. When the Hall sensor senses the magnet to determine that the pin corresponds to the annular groove, the controller transmits this information to the operator's remote control. The operator uses the remote control to control the motor to run, so that the pin is engaged in the annular groove.

[0036] In optional embodiments, such as Figure 4 As shown, two sets of limiting members 22 are provided and are located on opposite sides of the mounting base 21, and the number of through slots 212 corresponds to the number of limiting members 22. Engaging the hammer 23 from two directions not only improves the connection stability between the two but also prevents the cleaning trolley from becoming unbalanced during hoisting, thus improving hoisting safety.

[0037] In optional embodiments, such as Figure 2As shown, a housing 7 is provided around the periphery of the limiting member 22. The housing 7 includes a housing body 71 and a base plate 72. The base plate 72 is disposed on the upper surface of the water tank 4 and is supported and connected to the cleaning cart body 1 by a support rod 722. The housing body 71 is disposed on the surface of the base plate 72 facing away from the water tank 4 and encloses an installation space. The hoisting assembly 2 is installed in the installation space. The base plate 72 has a hole 721 corresponding to the water inlet 213 of the mounting seat 21. A guide pipe 41 is provided between the base plate 72 and the water inlet of the water tank 4. One end of the guide pipe 41 extends radially to form a connecting protrusion. The guide pipe 41 is connected to the base plate 72 by a connecting protrusion screw. The mounting seat 21 is also connected to the base plate 72 by screws. Furthermore, the length of the base plate 72 is greater than the width of the water tank 4. The part of the base plate 72 that protrudes from the water tank 4 is connected to the main body 1 of the cleaning cart via a support rod 722. The base plate 72 does not contact the water tank 4, thus avoiding the water tank 4 from being compressed and deformed, and reducing the risk of breakage.

[0038] In optional embodiments, such as Figure 1 As shown, the hoisting assembly 2 also includes a conical extension cover 24. One end of the conical extension cover 24 abuts against the end of the mounting base 21 away from the water tank 4 and is connected to the shell body 71. The diameter of the conical extension cover 24 gradually decreases from the end connected to the mounting base 21 towards the other end. Specifically, the design of the conical extension cover 24, combined with its structural design, increases its volume, allowing the drone's camera to quickly and accurately identify the position of the conical extension cover 24, thereby enabling the hammer 23 to be quickly positioned and connected to the mounting base 21. Furthermore, the diameter of the opening at the end of the conical extension cover 24 that connects to the shell body 71 corresponds to the conical connecting groove 211, allowing for a smooth transition after the conical extension cover 24 docks with the mounting base 21, facilitating the smooth lowering of the hammer 23 into the mounting base 21.

[0039] In optional embodiments, such as Figure 2As shown, the top of the shell body 71 has a mounting opening 711 corresponding to the mounting base 21. The mounting opening 711 communicates with the mounting space, and the mounting base 21 is installed in the mounting space through the mounting opening 711. A second connecting plate 712 is provided along the edge of the mounting opening 711, and the conical extension cover 24 and the mounting base 21 are connected to the mounting opening 711 through the second connecting plate 712. The shell body 71 is configured to provide sufficient support for the mounting base 21 and the conical extension cover 24, so that the two are stably connected above the water tank 4. This ensures that when using a drone to lift the cleaning cart, the lifting assembly 2 is not easily separated from the water tank 4, the connection strength is high, and the safety of lifting the cleaning cart is improved. In this embodiment, the mounting opening 711 is generally rectangular in shape, with notches formed along its four edges. The second connecting plate 712 is disposed at the notch, and the thickness of the second connecting plate 712 is consistent with the depth of the notch. The second connecting plate 712 and the shell body 71 can be integrally formed. The two ends of the second connecting plate 712 are threadedly connected to the periphery of the conical extension cover and the periphery of the mounting base 21, respectively, which improves the connection stability of the conical extension cover 24 and the mounting base 21 and prevents them from shifting relative to the shell body 71.

[0040] The cleaning cart is connected to the drone on the ground via a pendant 23. The pendant 23 has a conical structure. During assembly with the mounting base 21, the operator controls the motor 223 via a remote control and controller 3. The motor 223 rotates counterclockwise, and the pin 221 moves towards the motor 223 under the action of the connecting rod 222, retracting completely into the through slot 212. At this time, the pin 221 is in the unlocked state. After the pendant 23 is placed into the mounting base 21, the annular slot 232 corresponds to the pin 221, and the operator controls the motor 223 to rotate clockwise. Move the pin 221 to the right until it is engaged in the annular slot 232. The staff controls the drone to fly and transport the cleaning cart to the cleaning area and place it. Then, unlock the pin 221 and separate the drone from the cleaning cart. At this time, the cleaning cart cleans the photovoltaic panels. When the water level in the water tank 4 of the cleaning cart drops to the set liquid level, the drone uses its built-in camera to identify the hoisting connector 233 of the cleaning cart and connects to the cleaning cart in the above manner. It then replenishes the water tank 4 with water through the pipe, water inlet channel 231 and water guide pipe.

[0041] In summary, the cleaning vehicle is equipped with a hoisting assembly 2 that connects to a drone. This assembly combines the drone and the cleaning vehicle, allowing for rapid deployment of the cleaning vehicle in the cleaning area and improving efficiency. The hoisting assembly 2 includes a mounting base 21, a limiting component 22, and a lifting hammer 23. The lifting hammer 23 is connected to the drone via a steel wire rope. The mounting base 21 is installed on the cleaning vehicle, and the lifting hammer 23 is securely and stably mounted on the cleaning vehicle via the limiting component 22, improving the connection stability and lifting safety. This avoids manual transport and reduces work risks. The hoisting assembly 2 has a water inlet 213 and a water channel 231, facilitating the drone to replenish the water tank 4 via the hoisting assembly 2, extending the working time of the cleaning vehicle and ensuring its continuous operation.
