[0034] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] This application provides a photovoltaic panel cleaning device 1000. Please refer to [reference needed]. Figures 1-7 The 1000 photovoltaic panel cleaning equipment is used to clean stains on the surface of photovoltaic panels.

[0036] In one implementation method, please refer to Figure 1 and Figure 2 The photovoltaic panel cleaning equipment 1000 includes a drone 100, an undermount module 200, a joint module 300, a cleaning module 400, and a remote controller. The drone 100, undermount module 200, joint module 300, and cleaning module 400 constitute the main body of the photovoltaic panel cleaning equipment 1000. The remote controller is separate from the main body and can be held by the worker cleaning the photovoltaic panels. The worker can control any one of the drone 100, undermount module, joint module 300, and cleaning module 400 using the remote controller. In a specific embodiment, one remote controller can control multiple photovoltaic panel cleaning equipment 1000 units. For example, if the site includes multiple photovoltaic panel cleaning equipment 1000 units, the remote controller can selectively control one unit or simultaneously control multiple units to complete the cleaning work.

[0037] This application provides a photovoltaic panel cleaning device 1000. The device uses a drone 100 to carry an undermount module 200, a joint module 300, and a cleaning module 400 to fly above the photovoltaic panel. The cleaning bottle 410 of the cleaning module 400 is placed on the undermount module 200 to carry water and air sources. Then, the joint module 300 is rotated to a suitable angle with the photovoltaic panel, and the nozzle assembly 420 is used to clean the photovoltaic panel, thereby improving cleaning efficiency. At the same time, the drone 100, the undermount module 200, the joint module 300, and the cleaning module 400 are all controlled by a remote controller, which not only frees up manual labor but also achieves large-area cleaning, thereby solving the problem of high difficulty in cleaning existing photovoltaic panels.

[0038] In one implementation method, please refer to Figures 1-3 The drone 100 includes a main body 110 and a fan blade assembly 120 connected to the circumference of the main body 110. Specifically, the main body is disc-shaped or near-disc-shaped. The main body 110 may contain a memory, a receiver, and a controller. The memory stores the drone 100's operating program, the receiver receives remote commands from the remote controller, and the controller controls the fan blade assembly 120 to operate according to the remote commands. The fan blade assembly 120 is connected to the circumference of the main body 110, and the fan blade assembly 120 rotates via blades 122 to enable the photovoltaic panel cleaning device 1000 to perform takeoff, hovering, and landing actions.

[0039] In one implementation method, please refer to Figure 3 The fan blade assembly 120 includes multiple propellers 121 and multiple blades 122. The multiple propellers 121 are connected to the circumferential direction of the main body 110, and all multiple propellers 121 are rotatably connected to the main body 110. At least two blades 122 are connected to any one propeller 121. The blades 122 are connected to the end of the propeller 121 away from the main body 110, and the blades 122 are rotatably connected to the propeller 121.

[0040] In a specific embodiment, please refer to Figure 3 The fan blade assembly 120 includes eight propellers 121, and each propeller 121 is connected to at least two blades 122. When there are only two blades 122, the two blades 122 are arranged opposite each other (in a straight line). Of course, in other embodiments, the number of propellers 121 can be other, such as four, six, ten, etc., and the specific number is not limited; the number of blades 122 connected to each propeller 121 is also not limited, and can be three, four, five, six, etc.

[0041] In a specific embodiment, please refer to Figure 3Multiple propellers 121 are arranged in a ring at equal intervals around the main body 110. Each propeller 121 is rotatably connected to the main body 110. The propellers 121 can be rotated to unfold or retract, so that the UAV 100 includes a flight mode and a closed mode. In the flight mode, the propellers 121 are rotated to the unfolded state, and the multiple propellers 121 extend radially around the outer periphery of the main body 110, allowing the blades 122 to rotate. In the closed mode, the propellers 121 are rotated to the retracted state, and the section of the propeller 121 connected to the main body 110 rotates until the multiple propellers 121 are close together, extending towards the side of the main body 110 away from the lower attachment module 200.

[0042] In a specific embodiment, please refer to Figure 3 The multiple blades 122 can rotate relative to the propeller 121 to enable the drone 100 to take off. The multiple blades 122 on the propeller 121 can also be retracted. In the drone 100's closed mode, the propeller 121 is retracted, and the multiple blades 122 are retracted and folded together, with all the blades 122 extending towards the main body 110. In the drone 100's flight mode, the propeller 121 is deployed, and the multiple blades 122 are deployed accordingly, arranged in a ring. Optionally, the fan blade assembly 120 includes two types: one type has its blades 122 located on the side of the propeller 121 facing away from the ground, and the other type has its blades 122 located on the side of the propeller 121 facing the ground; and the two types of fan blade assemblies 120 are arranged alternately.

[0043] In one implementation method, please refer to Figure 3 The main body 110 includes a top surface 111 and a bottom surface 112 facing away from each other, with the bottom surface 112 of the main body 110 facing the ground. Multiple grooves 113 extending towards the center of the main body 110 are formed on the side of the main body 110, and the grooves 113 also penetrate the top surface 111 of the main body 110. The number of grooves 113 is the same as the number of propellers 121, and the propellers 121 are inserted into the grooves 113 from the side of the main body 110. It is understood that since the grooves 113 have no top wall, the propellers 121 can be folded upwards to achieve a closed mode; since the grooves 113 have a bottom wall, the propellers 121 can be folded downwards to be flush with the bottom wall of the grooves 113 to achieve a flight mode. In a specific embodiment, a rotating shaft is provided inside the groove 113, the rotating shaft passes through the propellers 121, and both ends of the rotating shaft are rotatably connected to the side wall of the groove 113. A driving component is installed inside the main body 110, and the driving component drives the propellers 121 to rotate via the rotating shaft.

[0044] This application designs a drone 100 with a main body 110 and a propeller 121. The propeller 121 is connected around the main body 110, and the blades 122 on the propeller 121 rotate to enable the drone 100 to perform takeoff, hovering, and landing. Furthermore, this application designs both the propeller 121 and the blades 122 to be retractable, thereby reducing the size of the drone 100 and simplifying the transportation of the photovoltaic panel cleaning equipment 1000.

[0045] In one implementation method, please refer to Figures 1-5 The lower hanging module 200 is connected to the main body 110, specifically to the bottom surface 112 of the main body 110, i.e., the side of the main body 110 facing the ground. The lower hanging module 200 includes a first frame 210 and a second frame 220. The first frame 210 is connected to the main body 110, and the second frame 220 is connected to the first frame 210. The first frame 210 is located on the outer periphery of the second frame 220. The cleaning bottle 410 is loaded on the second frame 220. The joint module 300 is connected to the second frame 220 and is located at the end of the second frame 220 facing away from the main body 110. The cleaning bottle 410 is disposed between the joint module 300 and the main body 110.

[0046] In a specific embodiment, please refer to Figure 4 and Figure 5 The lower-mounted module 200 is composed of multiple rods, some of which form the first frame 210, and others form the second frame 220. The first frame 210 serves as the outer frame, connecting to the ground as a supporting base after the photovoltaic panel cleaning equipment 1000 lands. The second frame 220 serves as the inner frame, supporting the cleaning bottle 410 and connecting the joint module 300.

[0047] In other embodiments, the under-mount module 200 may also be composed of multiple plates, some of which form the first frame 210, and other portions of which form the second frame 220. In other embodiments, the under-mount module 200 may also be composed of multiple plates and multiple rods. Of course, using only rods to make the first frame 210 and the second frame 220 can reduce the weight of the equipment and facilitate assembly and disassembly.

[0048] In one embodiment, the lower-mounted module 200 is detachably connected to the main body 110. Specifically, the lower-mounted module 200 can be detached from the drone 100, thereby increasing the flexibility of the photovoltaic panel cleaning equipment and adapting to different sizes of lower-mounted modules 200 to meet the needs of cleaning rings. In a specific embodiment, the main body 110 is provided with a first mating component, and the lower-mounted module 200 is provided with a second mating component. The first and second mating components are engaged and connected, thereby connecting the lower-mounted module 200 to the main body 110.

[0049] In one embodiment, the lower-mounted module 200 is rotatable relative to the main body 110. Specifically, the lower-mounted module 200 can rotate about the center of the main body 110, thereby providing the lower-mounted module 200 and the joint module 300 with a degree of freedom in the height direction. By rotating the lower-mounted module 200 and the joint module 300, the photovoltaic panel cleaning equipment can adapt to photovoltaic panels at different angles for cleaning. In a specific embodiment, the first mating member and the second mating member are detachably connected and rotatable relative to each other. The rotation of the second mating member relative to the first mating member causes the lower-mounted module 200 to rotate relative to the main body 110. Of course, a driving member is connected to the first or second mating member to drive the rotation of the first or second mating member.

[0050] The undermount module 200 provided in this application includes a first frame 210 and a second frame 220. The first frame 210 surrounds the outer periphery of the second frame 220, which not only protects the cleaning bottle 410 on the second frame 220, but also serves as a support structure for the photovoltaic panel cleaning equipment 1000, so that the photovoltaic panel cleaning equipment 1000 can stand stably on the ground.

[0051] In one implementation method, please refer to Figure 4 and Figure 5 The first frame 210 includes a first connector 2101, a first support 2102, and a second support 2103. The first support 2102 and the second support 2103 are connected to the main body 110. The first connector 2101 connects the first support 2102 and the second support 2103. The first support 2102 and the second support 2103 are located on opposite sides of the first connector 2101. The second frame 220 is connected to the first connector 2101 and is located between the support and the second support 2103. Along the height direction of the photovoltaic panel cleaning equipment, the first support 2102 and the second support 2103 have the same height, and the height of the second frame 220 is less than the height of the first support 2102.

[0052] In a specific embodiment, please refer to Figure 4 and Figure 5 The first frame 210 also includes independent first rods 2111 and second rods 2112, which can be connected in parallel to the bottom surface 112 of the main body 110. A first support member 2102 connects to the same end of the first rods 2111 and 2112, and a second support member 2103 connects to the other end of the first rods 2111 and 2112. The first support member 2102 and the second support member 2103 can be mirror images of each other; therefore, only the structure of the first support member 2102 is described here, while the structure of the second support member 2103 can be referenced.

[0053] In a specific embodiment, please refer to Figure 4 and Figure 5 The first support member 2102 includes a third rod 2113, a fourth rod 2114, and a fifth rod 2115. The third rod 2113 is connected to one end of the first rod 2111, the fourth rod 2114 is connected to one end of the second rod 2112 on the same side, and the fifth rod 2115 is connected at both ends to the other ends of the third rod 2113 and the fourth rod 2114, respectively. Specifically, the fifth rod 2115 is connected to the end of the third rod 2113 (and the fourth rod 2114) away from the first rod 2111 (and the second rod 2112). Preferably, the third rod 2113, the fifth rod 2115, and the fourth rod 2114 can be connected by an arc transition to prevent the lower-mounted module 200 from abrading the photovoltaic panel.

[0054] In a specific embodiment, please refer to Figure 4 and Figure 5 The first support member 2102 may further include a sixth rod 2116, the two ends of which are connected to the third rod 2113 and the fourth rod 2114 respectively, and the sixth rod 2116 is parallel to the fifth rod 2115. The sixth rod 2116 is located in the middle of the third rod 2113 and the fourth rod 2114. The first support member 2102 may be trapezoidal, wherein the side containing the first rod 2111 and the second rod 2112 is the short side, and the fifth rod 2115 is the long side. After the photovoltaic panel cleaning equipment 1000 lands, the fifth rod 2115 connects to the ground, and the third rod 2113 and the fourth rod 2114 are the hypotenuses used to connect the sixth rod 2116 and the fifth rod 2115.

[0055] In a specific embodiment, please refer to Figure 4 and Figure 5 The first connecting member 2101 includes an independent first crossbeam 2117 and a second crossbeam 2118. The two opposite ends of the first crossbeam 2117 are connected to the first rod 2111 and the second rod 2112, respectively. The two opposite ends of the second crossbeam 2118 are also connected to the first rod 2111 and the second rod 2112, respectively. The first crossbeam 2117 and the second crossbeam 2118 are spaced apart and parallel to each other. Specifically, the first crossbeam 2117 and the second crossbeam 2118 are located on the side of the first rod 2111 and the second rod 2112 facing away from the main body 110. The first crossbeam 2117 and the second crossbeam 2118 can be parallel to the fifth rod 2115 mentioned above. The second frame 220 is connected to the first crossbeam 2117 and the second crossbeam 2118. In a specific embodiment, both the first crossbeam 2117 and the second crossbeam 2118 can be square profiles, and the members of the supporting member can all be cylindrical profiles.

[0056] In one implementation method, please refer to Figure 4 and Figure 5The first frame 210 also includes a first support rod 2119 and a second support rod 2120 arranged at relative intervals. The two ends of the first support rod 2119 or the second support rod 2120 are connected to the first support member 2102 and the second support member 2103. Along the height direction of the photovoltaic panel cleaning equipment, the distance from the first support rod 2119 to the main body 110 is less than the distance from the farthest end of the first support member 2102 to the main body 110. The joint module 300 rotates to move closer to or away from the first support rod 2119 or the second support rod 2120.

[0057] In a specific embodiment, please refer to Figure 4 and Figure 5 The first support rod 2119 is connected at both ends to the third rod 2113 on the first support member 2102 and the third rod 2113 on the second support member 2103, respectively. The second support rod 2120 is connected at both ends to the fourth rod 2114 on the first support member 2102 and the fourth rod 2114 on the second support member 2103, respectively. Furthermore, the first support rod 2119 and the second support rod 2120 are at the same height. After the photovoltaic panel cleaning equipment 1000 lands, there is still a distance between the first support rod 2119 and the second support rod 2120 and the ground.

[0058] In one implementation method, please refer to Figure 4 and Figure 5 The second frame 220 includes a first frame 221 and a second frame 222 connected to each other. The first frame 221 is connected to a first connector 2101, and the second frame 222 is connected to the side of the first frame 221 facing away from the first connector 2101. The joint module 300 is connected to the second frame 222. The cleaning bottle 410 includes at least two bottles, and at least one bottle is housed in either the first frame 221 or the second frame 222.

[0059] In a specific embodiment, please refer to Figure 4 and Figure 5 The first frame 221 is connected to the first connector 2101 and is used to support at least one cleaning bottle 410. The second frame 222 is connected to the first frame 221 and is also used to support at least one cleaning bottle 410. Both the first frame 221 and the second frame 222 can be hexahedral frames, which can improve the stability of the second frame 220. At the same time, along the height direction of the photovoltaic panel cleaning equipment 1000, the height of the first frame 210 is greater than the height of the second frame 220, so after the photovoltaic panel cleaning equipment 1000 lands, there is still a gap between the second frame 220 and the ground.

[0060] In one embodiment, the second frame 220 includes multiple detachably connected rods, and the first frame 221 or the second frame 222 is assembled from multiple rods. The second frame 220 also includes a fixing component 223, which is connected to the rods. The cleaning bottle 410 is fixed to the second frame 220 by the fixing component 223.

[0061] In a specific embodiment, as described above, the second frame 220 is composed of multiple rods spliced ​​together, and both the first frame 221 and the second frame 222 are hexahedral in shape. The length and width of the first frame 221 and the second frame 222 can be the same, and the heights of the first frame 221 and the second frame 222 (the dimensions along the height direction of the photovoltaic panel cleaning equipment 1000) can be the same or different.

[0062] In a specific embodiment, the second frame 220 includes four parallel first horizontal bars (AD, not shown in the figure), wherein first horizontal bar A passes through the first horizontal beam 2117 and the second horizontal beam 2118, and first horizontal bar B passes through the first horizontal beam 2117 and the second horizontal beam 2118. The second frame 220 also includes four parallel vertical bars (AD, not shown in the figure), vertical bars A and B connect the two ends of the first horizontal bar A, and vertical bars C and D connect the two ends of the first horizontal bar B. First horizontal bar C is on the same side as the first horizontal bar A and connects one end of vertical bars A and B; first horizontal bar D is on the same side as the first horizontal bar B and connects one end of vertical bars C and D. The second frame 220 also includes four parallel second horizontal bars (AD, not shown in the figure). The extension directions of the second horizontal bars are perpendicular to those of the first horizontal bars. Second horizontal bar A connects the middle of vertical bars A and C; second horizontal bar B connects the middle of vertical bars B and D; second horizontal bar C connects the same end of first horizontal bars C and D; and second horizontal bar D connects the other end of first horizontal bars C and D. Thus, first horizontal bars A, first horizontal bars B, vertical bars, and second horizontal bars A and B together form the first frame 221; first horizontal bars C, first horizontal bars D, vertical bars, and second horizontal bars together form the second frame 222.

[0063] In other embodiments, the horizontal and vertical bars on the second frame 220 can also be spliced ​​in other ways, which are not specifically limited here. The connection method of the horizontal and vertical bars provided in the above embodiments can maximize the load capacity and strength of the second frame 220, and reduce the weight of the second frame 220, thereby reducing the load weight of the drone 100.

[0064] In a specific embodiment, the second frame 220 further includes two parallel first connecting rods (A and B, not shown in the figure). The two ends of the first connecting rods are respectively connected to the second crossbar A and the second crossbar B described above. The cleaning bottle 410 is placed on the two first connecting rods, and the length direction of the cleaning bottle 410 can be perpendicular to the first connecting rods.

[0065] In a specific embodiment, please refer to Figure 4 and Figure 5 The fixing component 223 includes a first fixing member 2231, a second fixing member 2232, and a strap 2233. The cleaning bottle 410 is located between the first fixing member 2231 and the second fixing member 2232. The two ends of the strap 2233 are connected to the first fixing member 2231 and the second fixing member 2232, respectively, and the strap 2233 is wrapped around the outer periphery of the cleaning bottle 410. Specifically, the fixing component 223 consists of two sets, one set is disposed on a first connecting rod A, and the other set is disposed on another first connecting rod B. Taking the first connecting rod A as an example, one end of the strap 2233 is detachably connected to the first fixing member 2231, and the other end of the strap 2233 is detachably connected to the second fixing member 2232. Optionally, both the first fixing member 2231 and the second fixing member 2232 can be detachably wrapped around the outer periphery of the first connecting rod, so that the tightness of the fixing assembly 223 on the cleaning bottle 410 can be controlled by adjusting the distance between the first fixing member 2231 and the second fixing member 2232.

[0066] In one embodiment, both the first frame 221 and the second frame 222 are cylindrical and arranged in parallel, meaning both are connected to the first connector 2101. Furthermore, the axial direction of the first frame 221 and the second frame 222 is the height direction of the photovoltaic panel cleaning device 1000. The advantage of this arrangement is that the shapes of the two frames are similar to the shape of the cleaning bottle 410, allowing for better containment of the bottle. The cleaning bottle 410 is placed into the frames from bottom to top, and its opening can face downwards, thereby reducing the need for pipework, improving gas and liquid output efficiency, and minimizing gas loss in the pipes.

[0067] In one implementation method, please refer to Figures 1-7 The joint module 300 is connected to the lower hanging module 200, and the joint module 300 is rotatable relative to the lower hanging module 200. The joint module 300 is rotatably connected to the side of the second frame 222 facing away from the drone 100. Based on the above embodiment, the second frame 222 is composed of multiple rods, and the joint module 300 is rotatably connected to a rod at the bottom of the second frame 222.

[0068] In a specific embodiment, please refer to Figure 6The joint module 300 includes a first drive component 330, which is fixedly connected to the second frame 222. The first drive component 330 drives other components of the joint module 300 to rotate relative to the second frame 222. Optionally, the first drive component 330 can be a motor. The first drive component 330 can be remotely driven by a remote control, which controls the first drive component 330 to rotate the lower hanging module 200 to a suitable angle.

[0069] In a specific embodiment, the second frame 220 further includes at least one second connecting rod, the two ends of which are respectively connected to the middle of the first crossbar C and the first crossbar D, and the first drive member 330 of the joint module 300 can be fixedly connected to the middle of the second connecting rod.

[0070] In a specific embodiment, the second frame 220 can rotate independently. That is, in the above embodiment where the lower hanging module 200 is rotatable relative to the main body 110, the first frame 210 is fixedly connected to the main body 110, and the second frame 220 can rotate relative to the first frame 210 and the main body 110. Because the joint module 300 is connected to the second frame 220 of the lower hanging module 200, the second frame 220 can be set to rotate independently in order to provide the joint module 300 with additional degrees of freedom.

[0071] In one implementation method, please refer to Figure 6 The lower hanging module 200 includes a first joint rod 310 and a second joint rod 320. The first joint rod 310 is connected to the lower hanging module 200 and rotates upward in a first circumference relative to the lower hanging module 200. The second joint rod 320 is connected to the first joint rod 310 and rotates upward in a second circumference relative to the first joint rod 310. The first circumferential direction and the second circumferential direction intersect.

[0072] In a specific embodiment, please refer to Figure 6 Both the first joint rod 310 and the second joint rod 320 can be rod-shaped components. The first joint rod 310 is connected to the first driving member 330 mentioned above, and the first joint rod 310 and the second joint rod 320 are connected by the second driving member 340. The first driving member 330 drives the first joint rod 310 to rotate relative to the second frame 222, and the second driving member 340 drives the second joint rod 320 to rotate relative to the first joint rod 310.

[0073] In a specific embodiment, please refer to Figure 6One end of the first joint rod 310 is connected to the first driving member 330, and the other end is connected to the second driving member 340. The first driving member 330 drives the first joint rod 310 to rotate around itself, with the first joint rod 310 approaching the first support rod 2119 or the second support rod 2120. The second driving member 340 can be remotely driven by a remote control, which controls the second driving member 340 to rotate the second joint rod 320 to a suitable angle. It can be understood that the first driving member 330 can drive the first joint rod 310 to swing and rotate in a pendulum-like manner, and the second driving member 340 can drive the second joint rod 320 to rotate in a propeller-like manner.

[0074] In one implementation method, please refer to Figure 6 The first joint rod 310 is connected to the middle of the second joint rod 320. The distance ratio from the connection position of the first joint rod 310 and the second joint rod 320 to both ends of the second joint rod 320 satisfies 0.8 to 1.2. The nozzle assembly 420 is arranged sequentially along the length direction of the second joint rod 320. The pipe assembly is fixed on the first joint rod 310 and the second joint rod 320.

[0075] In a specific embodiment, please refer to Figure 6 The second driving member 340 is located at the middle position of the second joint rod 320, so the second driving member 340 drives the second joint rod 320 to rotate around this middle position. Preferably, the distance from the middle position of the second joint rod 320 to both ends of the second joint rod 320 is equal (i.e., the distance ratio is 1).

[0076] In one embodiment, the first joint rod 310 is connected to the end of the second joint rod 320, meaning the first joint rod 310 and the second joint rod 320 can be connected end-to-end. Furthermore, the first joint rod 310 and the second joint rod 320 rotate circumferentially upwards in two different dimensions.

[0077] In a specific embodiment, the second driving member 340 includes a stator and a rotor rotatably connected, wherein the stator is fixedly connected to the first joint rod 310, and the rotor is connected to the second joint rod 320. Optionally, the second joint rod 320 passes through the rotor and is detachably connected to it. The position of the rotor on the second joint rod 320 is adjustable. The rotor is located in the middle of the second joint rod 320, i.e., the second driving member 340 is located at the middle position of the second joint rod 320, as described above. The rotor is located at the end of the second joint rod 320, i.e., the second driving member 340 is located at the end of the second joint rod 320, as described above. The advantage of this structure is that the second joint rod 320 is replaceable, which not only facilitates maintenance but also allows for adaptive adjustment of the length of the second joint rod 320 to meet the requirements of a clean environment.

[0078] In one embodiment, the lower module 200 may also include only the first joint rod 310, the nozzle assembly 420 is arranged sequentially along the length direction of the first joint rod 310, and the pipe assembly is fixed on the first joint rod 310.

[0079] In a specific embodiment, the first driving component 330 also includes a stator and a rotor that are rotatably connected, wherein the stator is fixedly connected to the second connecting rod, and the rotor is connected to the first joint rod 310. Optionally, the first joint rod 310 can be detachably inserted into the rotor. The advantage of this structure is that the first joint rod 310 is replaceable, which not only facilitates maintenance but also allows for adaptive adjustment of the length of the first joint rod 310 to meet the requirements of a clean environment.

[0080] In one implementation method, please refer to Figures 1-7 The cleaning module 400 includes a cleaning bottle 410, a pipe assembly, and a nozzle assembly 420. The pipe assembly is connected to the cleaning bottle 410, and the nozzle assembly 420 is connected to the pipe assembly. The cleaning bottle 410 is loaded on the lower hanging module 200. The pipe assembly is connected to the lower hanging module 200 and the joint module 300, and the nozzle assembly 420 is connected to the joint module 300.

[0081] In one implementation method, please refer to Figure 3 and Figure 7 The cleaning bottle 410 includes a gas bottle and a liquid bottle (not shown in the figure), the pipeline assembly includes a first pipeline and a second pipeline, and the nozzle assembly 420 includes a gas nozzle 421 and a liquid nozzle 422. The gas bottle is connected to the first pipeline, the gas nozzle 421 is connected to the first pipeline, and the liquid nozzle 422 is connected to the second pipeline.

[0082] In a specific embodiment, please refer to Figure 3 The gas cylinder is fixed to the first frame 221, and the liquid cylinder is fixed to the second frame 222; alternatively, the liquid cylinder can be fixed to the first frame 221, and the gas cylinder to the second frame 222. Both the first and second pipes are fixed to the outer periphery of the rods of the lower hanging module 200 and the joint module 300. There are multiple gas nozzles 421 and multiple liquid nozzles 422, preferably the same number. One gas nozzle 421 and one liquid nozzle 422 constitute one nozzle assembly 420. There are multiple nozzle assemblies 420, and these multiple nozzle assemblies 420 are sequentially fixed to the second joint rod 320 along its length, preferably at equal intervals.

[0083] In a specific embodiment, please refer to Figure 6 and Figure 7The nozzle assembly 420 is detachably connected to the second joint rod 320. Optionally, the nozzle assembly 420 further includes a second connector 423, wherein the second connector 423 is detachably connected to the second joint rod 320, and both the gas nozzle and the liquid nozzle 422 are connected to the second connector 423.

[0084] In a specific embodiment, please refer to Figure 7 The second connector 423 is sleeved on the outer periphery of the second joint rod 320, so that the second connector 423 can rotate around the second joint rod 320, thereby further adjusting the spray angle of the nozzle assembly 420. In other embodiments, the gas nozzle and / or liquid nozzle 422 can rotate relative to the second connector 423, thereby further adjusting the spray angle of the gas nozzle and / or liquid nozzle 422.

[0085] In a specific embodiment, the pipe assembly is integrated with the hanging module 200 and the joint module 300. Specifically, based on the above implementation, the hanging module 200 is composed of multiple rods spliced ​​together, and the joint module 300 also includes two movable joint rods. The interior of the rods and joint rods can be a hollow structure, and through holes can be opened on the rods and joint rods. The pipe assembly can pass through the through holes into the interior of the rods and extend inside the rods, and also pass into the interior of the joint rods and extend inside the rods. The pipe assembly exits from the position of the corresponding nozzle assembly 420 of the second joint rod 320 and connects to the nozzle.

[0086] In a specific embodiment, the photovoltaic panel cleaning device 1000 may not require additional piping components. The lower-mounted module 200 and the joint module 300 can be hollow structures with internal channels, serving to transport gas and liquid. For example, the cleaning bottle 410 is connected to a rod in the lower-mounted module 200 via a first adapter. The rod has a first channel extending from the first adapter to the connection point between the lower-mounted module 200 and the joint module 300. The lower-mounted module 200 and the joint module 300 are also connected via a second adapter. The joint rod has a second channel, which connects the first and second channels. The second channel extends from the second adapter to the connection point between the joint module 300 and the nozzle assembly 420. The joint module 300 and the nozzle assembly 420 are then connected via a third adapter. This reduces the need for piping components, decreases the load, and avoids interference from tangled piping components.

[0087] In one embodiment, the remote controller is used to control the drone 100 to start flying above the photovoltaic panel and to control the drone 100 to hover at a preset distance between the lower module 200 and the photovoltaic panel, and to use the fan blade assembly 120 to initially clean the photovoltaic panel; the remote controller is also used to control the joint module 300 to rotate to a preset angle so that the nozzle assembly 420 faces the photovoltaic panel, and the remote controller is used to open the cleaning bottle 410, and to use the nozzle assembly 420 to spray gas and / or liquid to clean the photovoltaic panel.

[0088] Therefore, based on the above embodiments, this application specifically provides a photovoltaic panel cleaning device 1000 that is lightweight and capable of cleaning photovoltaic panels in multiple dimensions. The main body of the photovoltaic panel cleaning device 1000 includes a drone 100 for flight and a hanging module 200 connected to the drone 100. In a specific embodiment, the hanging module 200 can be assembled from multiple rods, forming a cage-like structure, which makes the hanging module 200 lighter. Furthermore, the assembly of multiple rods improves the design flexibility of the hanging module 200, ensuring that the size of the cleaning bottle 410 is not restricted and can be adjusted according to the parameters and shape of the cleaning bottle 410. Meanwhile, in a specific embodiment, the photovoltaic panel cleaning equipment 1000 can clean photovoltaic panels in at least two dimensions. Spraying in two dimensions can be achieved through the movable first joint rod 310 and the second joint rod 320. In addition, the lower hanging module 200 can be rotated to achieve spraying in a third dimension, and the nozzle assembly 420 can be set to achieve spraying in a fourth dimension. This can improve cleaning efficiency and adapt to photovoltaic panels with different installation angles and photovoltaic systems in different environments.

[0089] This application also provides a method for using the photovoltaic panel cleaning equipment 1000; please refer to [reference needed]. Figure 8 The photovoltaic panel cleaning equipment 1000 uses this method to clean photovoltaic panels.

[0090] In one implementation method, please refer to Figure 8 The specific steps for using the photovoltaic panel cleaning equipment 1000 are as follows:

[0091] In step S10, the remote controller starts the drone 100, and the main body of the photovoltaic panel cleaning equipment flies above the photovoltaic panel.

[0092] In step S20, the remote controller controls the drone 100 to hover until the lower-mounted module 200 and the photovoltaic panel are at a preset distance.

[0093] In step S30, the remote control controls the joint module 300 to rotate to a preset angle.

[0094] In step S40, the remote control controls the cleaning bottle 410 to open, and the nozzle assembly 420 sprays gas and / or liquid to clean the photovoltaic panel.

[0095] In step S50, the remote controller controls the joint module 300 to return to the initial mode, and the drone 100 flies away from the photovoltaic panel and lands.

[0096] In one embodiment, in step S10, the remote controller controls the drone 100 to start, and the main body of the photovoltaic panel cleaning equipment flies to above the photovoltaic panel. Specifically, the remote controller controls multiple propellers 121 and fan blades to unfold so that the drone 100 enters flight mode; then the remote controller controls the drone 100 to take off and fly to above the photovoltaic panel.

[0097] In one embodiment, in step S20, a sensing component may be provided on the photovoltaic panel cleaning device. The function of the sensing component includes sensing the distance between the photovoltaic panel cleaning device and the photovoltaic panel, preferably sensing the distance between the bottom of the first frame 210 and the photovoltaic panel. The sensing component can be electrically connected to the controller in the drone 100 and transmit electrical signals to the controller.

[0098] In one embodiment, in step S20, the remote controller controls the drone 100 to hover until the lower-mounted module 200 and the photovoltaic panel are at a preset distance. Specifically, this includes: the drone 100's internal memory stores a preset distance between the bottom of the first frame 210 and the photovoltaic panel; the remote controller controls the drone 100 to move towards the photovoltaic panel, and the sensing component senses the actual distance between the bottom of the first frame 210 and the photovoltaic panel in real time and transmits the actual distance to the controller; the controller compares the difference between the preset distance and the actual distance. When the preset distance is greater than the actual distance, the drone 100 continues to move towards the photovoltaic panel; when the preset distance is equal to the actual distance, the drone 100 stops moving and sends a hovering signal to the controller; when the preset distance is less than the actual distance, the drone 100 stops moving and sends a danger signal to the controller.

[0099] In one embodiment, the purpose of setting a preset distance between the hanging module 200 and the photovoltaic panel in step S20 is twofold. Firstly, it ensures that the joint module 300 can rotate smoothly to unfold without touching the photovoltaic panel. If the hovering distance is not set, the spraying distance will be insufficient, resulting in a poor cleaning effect, or the joint module 300 and the photovoltaic panel will be too close and collide, damaging both the photovoltaic panel and the joint module 300. Secondly, as the drone 100 approaches the photovoltaic panel, the rotation of the drone 100's blades can initially disperse the dust on the photovoltaic panel, thereby achieving the purpose of preliminary cleaning and reducing the workload of the cleaning bottle 410's air blowing in the later stages, thus saving gas.

[0100] In one embodiment, in step S30, the remote controller controls the joint module 300 to rotate to a preset angle, specifically including: the remote controller controls the first joint rod 310 to rotate so that the first joint rod 310 is perpendicular to the ground; the remote controller controls the second joint rod 320 to rotate so that the second joint rod 320 is parallel to the photovoltaic panel. Here, rotating the joint module 300 to the preset angle means rotating the second joint rod 320 to an angle parallel to the photovoltaic panel.

[0101] In one embodiment, in step S30, before the joint module 300 rotates, it retracts, meaning the first joint rod 310 is close to the first support rod 2119 or the second support rod 2120, and the second joint rod 320 is parallel or approximately parallel to the first joint rod 310. Therefore, in this step, the two joint rods need to be extended to obtain the closest cleaning distance and the maximum cleaning angle. It should be explained that when the photovoltaic panel cleaning equipment 1000 descends, the joint module 300 retracts to avoid collision between the joint components and the ground. In the above embodiment, the distance from the first support rod 2119 to the main body 110 is less than the distance from the farthest end of the first support member 2102 to the main body 110. The rotation of the joint module 300 to move closer to or away from the first support rod 2119 or the second support rod 2120 provides space for the joint module 300 to retract.

[0102] In one embodiment, after the remote controller controls the joint module 300 to rotate to a preset angle in step S30, the method may further include: the remote controller controlling the drone 100 to rotate the main body of the photovoltaic panel cleaning device 1000, or the remote controller controlling the lower module 200 to rotate, so that the second joint rod 320 rotates to be parallel to the wide side of the photovoltaic panel. The wide side is perpendicular to the installation direction of the photovoltaic panel on the photovoltaic support.

[0103] In one embodiment, in step S30, the sensing component further functions to sense the parallelism between the second joint rod 320 and the photovoltaic panel. Preferably, it senses the parallelism between the second joint rod 320 and the wide side of the photovoltaic panel. The sensing component can be electrically connected to the controller in the UAV 100 or to the drive unit of the lower-mounted module 200, and transmit electrical signals to it.

[0104] In one embodiment, in step S30, it should be explained that rotating the second joint rod 320 to be parallel to the photovoltaic panel means that the second joint rod 320 is parallel to the surface of the photovoltaic panel. Therefore, it is possible that the second joint rod 320 is angled above the photovoltaic panel, intersecting with the long and wide sides of the photovoltaic panel. This would require the photovoltaic panel cleaning equipment 1000 to continuously adjust its flight path to adapt to the installation direction of the photovoltaic panel during the cleaning process. By pre-controlling the rotation of the second joint rod 320 to be parallel to the wide side of the photovoltaic panel, the photovoltaic panel cleaning equipment 1000 can fly in a straight line along the installation direction of the photovoltaic panel to complete one cleaning cycle, thereby improving cleaning efficiency.

[0105] In one embodiment, in step S40, the remote control controls the cleaning bottle 410 to open, and the nozzle assembly 420 sprays gas and / or liquid to clean the photovoltaic panel. Specifically, the remote control first controls the gas bottle and gas nozzle 421 to start, first purging the photovoltaic panel with gas, and then controls the gas bottle and gas nozzle 421 to close. Then, the remote control first controls the liquid bottle and liquid nozzle 422 to start, first cleaning the photovoltaic panel with gas, and then controls the liquid bottle and liquid nozzle 422 to close.

[0106] In one embodiment, in step S40, the gas cylinder and gas nozzle 421, and the liquid cylinder and liquid nozzle 422 may be started intermittently and periodically. The specific starting method can be set according to the requirements.

[0107] In one embodiment, in step S40, when the nozzle assembly 420 can rotate relative to the second joint rod 320, the remote controller can control the rotation angle of the nozzle assembly 420 to adapt to the spraying range.

[0108] In one embodiment, in step S50, the remote controller controls the joint module 300 to return to the initial mode, and the drone 100 flies away from the photovoltaic panel and lands. Specifically, this includes controlling the second joint rod 320 to retract, and then controlling the first joint rod 310 to retract, so that the drone 100 flies away from the photovoltaic panel and lands.

Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application are still within the scope of this application.
