[0041] In the specific embodiment, please refer to Figure 3, multiple paddle rods 121 are arranged in a circular shape with equal spacing in the circumferential direction of the main body 110. Each paddle rod 121 is rotatably connected to the main body 110, and the paddle rod 121 is rotated to be unfolded or retracted, so that the drone 100 includes a flight mode and a closed mode. Among them, in the flight mode, the paddle rod 121 rotates to an unfolded state, and multiple paddle rods 121 extend radially around the outer periphery of the main body 110, and the paddle rod 121 extends so that the blades 122 can rotate; in the closed mode, the paddle rod 121 rotates to a retracted state, and a section of the paddle rod 121 connected to the main body 110 rotates until the multiple paddle rods 121 are close to each other, and the paddle rod 121 extends toward the side of the main body 110 away from the lower hanging module 200.

[0042] In the specific embodiment, please refer to Figure 3 , the multiple blades 122 can not only rotate relative to the paddle rod 121 to make the drone 100 take off.

[0088] Therefore, based on the above-mentioned embodiments, the present application specifically provides a photovoltaic panel cleaning device 1000 that is lightweight and can clean photovoltaic panels in multiple dimensions. Among them, the main body of the photovoltaic panel cleaning device 1000 includes a drone 100 for flying, and a lower hanging module 200 connected to the drone 100. In a specific embodiment, the lower hanging module 200 can be assembled from a plurality of rods, so that the lower hanging module 200 forms a cage structure, and the lower hanging module 200 of this structure is lighter; and the assembly of multiple rods also improves the designability of the lower hanging module 200. The lower hanging module 200 will not restrict the size of the cleaning bottle 410, and can be adjusted accordingly according to the parameter shape of the cleaning bottle 410. At the same time, in a specific embodiment, the photovoltaic panel cleaning device 1000 can clean the photovoltaic panel in at least two dimensions, and can achieve two-dimensional spraying through the movable first joint rod 310 and the second joint rod 320. In addition, the lower hanging module 200 can be arranged to rotate to achieve third-dimensional spraying, and the nozzle assembly 420 can be arranged to achieve fourth-dimensional spraying, thereby improving the cleaning efficiency and adapting 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 device 1000, please refer to Figure 8 , the photovoltaic panel cleaning device 1000 uses this method to clean the photovoltaic panel.

[0090] In one implementation, please refer to Figure 8 The method for using the photovoltaic panel cleaning device 1000 specifically includes the following steps:

[0091] In step S10, the remote controller controls the drone 100 to start, and the main body of the photovoltaic panel cleaning device flies above the photovoltaic panel.

[0092] Step S20, the remote controller controls the drone 100 to hover until the lower hanging module 200 is at a preset distance from the photovoltaic panel.

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

[0094] Step S40, the remote controller 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 device flies above the photovoltaic panel, specifically including: 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 above the photovoltaic panel.

[0097] In one embodiment, in step S20, the photovoltaic panel cleaning device may be provided with a sensor component, and the function of the sensor 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 sensor component may be electrically connected to the controller in the drone 100 and transmit an electrical signal to the controller.

[0098] In one embodiment, in step S20, the remote controller controls the drone 100 to hover until the lower hanging module 200 has a preset distance from the photovoltaic panel, specifically including: a preset distance between the bottom of the first frame 210 and the photovoltaic panel is set in the memory inside the drone 100; the remote controller controls the drone 100 to move toward the photovoltaic panel, and the sensor 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 toward the photovoltaic panel, when the preset distance is equal to the actual distance, the drone 100 stops moving and feeds back a hovering signal to the controller, and when the preset distance is less than the actual distance, the drone 100 stops moving and feeds back a danger signal to the controller.

[0099] In one embodiment, in step S20, setting a preset distance between the lower hanging module 200 and the photovoltaic panel has two purposes. On the one hand, it is to enable the joint module 300 to rotate smoothly to unfold without touching the photovoltaic panel. If the hovering distance is not set, the spraying distance will be insufficient and the cleaning effect will be poor, or the joint module 300 and the photovoltaic panel are too close and collide with each other, damaging the photovoltaic panel and the joint module 300. On the other hand, in the process of the drone 100 approaching the photovoltaic panel, the rotation of the fan blades of the drone 100 can initially blow away the dust on the photovoltaic panel, so as to achieve the purpose of preliminary cleaning, thereby reducing the workload of the later cleaning bottle 410 for air blowing and 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. The rotation of the joint module 300 to the preset angle means that the second joint rod 320 rotates to an angle parallel to the photovoltaic panel.

[0101] In one embodiment, in step S30, before the joint module 300 rotates, the joint module 300 is folded, that is, 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 unfolded to obtain the nearest cleaning distance and the maximum cleaning angle. It should be explained that when the photovoltaic panel cleaning device 1000 lands, in order to avoid the joint assembly from colliding with the ground, the joint module 300 will be folded, and in the above-mentioned 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, and the joint module 300 rotates to approach or move away from the first support rod 2119 or the second support rod 2120, which is to reserve space for the joint module 300 to be folded.

[0102] In one embodiment, in step S30, after the remote controller controls the joint module 300 to rotate to a preset angle, the method may further include: the remote controller controls the drone 100 to drive the main body of the photovoltaic panel cleaning device 1000 to rotate, or the remote controller controls the lower hanging 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 paving direction of the photovoltaic panel on the photovoltaic bracket.

[0103] In one embodiment, in step S30, the function of the sensor assembly further includes sensing the parallel state of the second joint rod and the photovoltaic panel. Preferably, the second joint rod 320 is sensed to be parallel to the wide side of the photovoltaic panel. The sensor assembly can be electrically connected to the controller in the drone 100 or to the driving member of the lower hanging module 200, and transmit an electrical signal thereto.

[0104] In one embodiment, in step S30, it is necessary to explain that the second joint rod 320 rotates to be parallel to the photovoltaic panel, which means that the second joint rod 320 is parallel to the panel surface of the photovoltaic panel, so it is possible that the second joint rod 320 is obliquely above the photovoltaic panel, and the second joint rod 320 intersects with the long side and the wide side of the photovoltaic panel, which causes the photovoltaic panel cleaning device 1000 to continuously adjust the flight path of the device during the cleaning process to adapt to the paving direction of the photovoltaic panel. By pre-controlling the second joint rod 320 to rotate to be parallel to the wide side of the photovoltaic panel, the photovoltaic panel cleaning device 1000 can fly in a straight line along the paving direction of the photovoltaic panel to complete one cleaning, thereby improving the cleaning efficiency.

[0105] In one embodiment, in step S40, the remote control controls the cleaning bottle 410 to start, and the nozzle assembly 420 sprays gas and / or liquid to clean the photovoltaic panel, specifically including: the remote control first controls the gas bottle and the gas nozzle 421 to start, first performs gas purge on the photovoltaic panel, and then the remote control controls the gas bottle and the gas nozzle 421 to close; then the remote control first controls the liquid bottle and the liquid nozzle 422 to start, first performs gas cleaning on the photovoltaic panel, and then the remote control controls the liquid bottle and the liquid nozzle 422 to close.

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

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

[0108] In one embodiment, in step S50, the remote control controls the joint module 300 to restore to the initial mode, and the drone 100 flies away from the photovoltaic panel and lands, specifically including: controlling the second joint rod 320 to retract, and then controlling the first joint rod 310 to retract, and the drone 100 flies away from the photovoltaic panel and lands.
