[0025] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. The following describes various embodiments of the present invention in detail in conjunction with the drawings.

[0026] Example 1

[0027] See also Figures 1 to 5 The present invention preferably provides a technical solution: a drone photovoltaic panel cleaning device, comprising a drone body 1; a water tank 2, the water tank 2 is fixed to the bottom of the fuselage of the drone body 1; an installation box 3, the installation box 3 is arranged at the bottom of the water tank 2; a cleaning component 4, the cleaning component 4 is arranged on the water tank 2, and the cleaning component 4 includes: a pump body 41, the pump body 41 is fixed to the side wall of the water tank 2, and the water inlet pipe of the pump body 41 is fixed and connected to the side wall of the water tank 2; a water delivery pipe 42, one end of the water delivery pipe 42 is fixed and connected to the water outlet pipe of the pump body 41; a nozzle 43, the inlet of the nozzle 43 is connected to the end of the water delivery pipe 42 away from the pump body 41; the drone photovoltaic panel cleaning device also includes: an adjustment mechanism 5, the adjustment mechanism 5 is arranged on the installation box 3, and is used to adjust the spray angle of the nozzle 43.

[0028] In this embodiment, the drone body 1 belongs to the prior art and need not be described in detail. The water pipe 42 is made of a hose, such as rubber or silicone, to adapt to the change of the angle of the nozzle 43. The pump body 41 can be a universal water pump, such as a pump body 41 of model DC40F-2460.

[0029] Specifically: when cleaning photovoltaic panels with different inclination angles, the staff only needs to adjust the spray angle of the nozzle 43 through the adjustment mechanism 5, which changes the traditional technology that requires adjusting the angle of the nozzle 43 by adjusting the angle of the drone body 1, reducing the difficulty of operation.

[0030] It is worth noting that when the drone body 1 is hovering (not flying), by adjusting the spray angle of the nozzle 43, the cleaning range of the photovoltaic panel by the cleaning device is expanded, which is conducive to promotion and use.

[0031] Furthermore, the adjusting mechanism 5 includes an adjusting component 51 and a driving component 52. The adjusting component 51 includes: a rotating rod 511, the rotating rod 511 is penetrated and arranged on the side wall of the installation box 3 and is rotatably connected to the installation box 3; a first connecting rod 512, one end of the first connecting rod 512 is hinged to an end of the rotating rod 511 located outside the installation box 3; a second connecting rod 513, one end of the second connecting rod 513 is hinged to an end of the first connecting rod 512 away from the rotating rod 511; a third connecting rod 514, an end of the second connecting rod 513 away from the first connecting rod 512 penetrates the middle section of the third connecting rod 514 and is rotatably connected, the upper end of the third connecting rod 514 is rotatably connected to the side wall of the installation box 3, and a mounting block 515 connected to the nozzle 43 is fixed on the side wall of the third connecting rod 514 near its lower end. The driving component 52 is used to drive the rotating rod 511 to rotate.

[0032] Combination Figure 2 As shown, when adjusting the spraying angle of the nozzle 43, the staff only needs to drive the rotating rod 511 to rotate through the driving assembly 52. ​​The rotating rod 511 pulls the third connecting rod 514 through the first connecting rod 512 and the second connecting rod 513, so that the third connecting rod 514 rotates around the hinge axis between the third connecting rod 514 and the mounting box 3, so that the angle of the mounting block 515 and the nozzle 43 can be adjusted within a certain range, which is conducive to completing the adjustment of the angle of the nozzle 43 without changing the tilt angle of the drone body 1.

[0033] Furthermore, the nozzle 43 passes through the mounting block 515 and is threadedly connected to the mounting block 515 , and a polygonal block 431 is fixed to the outer wall of the nozzle 43 , so that the staff can detachably install the nozzle 43 on the mounting block 515 .

[0034] Furthermore, the driving component 52 is arranged in the installation box 3, and the driving component 52 includes: a motor 521 (using a commonly used servo motor 521), the motor 521 is fixed on the inner bottom wall of the installation box 3; a first worm 522, the lower end of the first worm 522 is fixed to the output end of the motor 521; a first worm wheel 523, the first worm wheel 523 is fixedly mounted on the rotating rod 511 and is located in the installation box 3, and the first worm wheel 523 is meshed with the first worm 522.

[0035] Combination Figure 3 and Figure 4 As shown, when the rotating rod 511 is driven to rotate by the driving assembly 52, the staff only needs to turn on the motor 521. After the motor 521 works, it drives the first worm 522 to rotate, thereby rotating the first worm gear 523, thereby rotating the rotating rod 511 fixed to the first worm gear 523, so as to adjust the spraying angle of the nozzle 43.

[0036] Furthermore, the cleaning components 4 are provided with two groups and are symmetrically distributed on both sides of the water tank 2, the adjusting components 51 are provided with two groups, and are respectively connected to the nozzles 43 of the two groups of cleaning components 4, the adjusting mechanism 5 also includes a transmission component 53, the transmission component 53 is used to drive the rotating rod 511 away from the side of the motor 521 to rotate, and the transmission component 53 includes: a driving gear 531, the driving gear 531 is fixed to the end of the rotating rod 511 close to the side of the motor 521; a first fixed plate 532, the first fixed plate 532 is fixed to the inner wall of the mounting box 3; a driven gear 533, the driven gear 533 is rotatably mounted on the first fixed plate 532, and meshes with the driving gear 531; a rotating plate 534, the rotating plate 534 is fixed to the end of the rotating rod 511 away from the side of the motor 521; a ring gear 535, the ring gear 535 is fixed to the side of the rotating plate 534 away from the rotating rod 511, and meshes with the driven gear 533.

[0037] Combination Figure 3 and Figure 4 As shown, when the motor 521 is working and driving the rotating rod 511 on one side to rotate, the driving gear 531 rotates synchronously, and the driving gear 531 drives the driven gear 533 meshing with it, the ring gear 535 meshing with the driven gear 533, the rotating plate 534 fixed with the ring gear 535, and the rotating rod 511 on the other side to rotate, so that the angle of the nozzle 43 on the other side can be adjusted, and the adjustment directions of the nozzles 43 on both sides are opposite. When the drone body 1 is flying, the cleaning range of the drone is maximized.

[0038] Furthermore, two fixed blocks 21 are fixed at the bottom of the water tank 2, and the two fixed blocks 21 are symmetrically distributed on both sides of the installation box 3. The height of the top of the fixed block 21 is greater than the height of the top of the installation box 3. A center rod 31 fixed to the installation box 3 is penetrated through the side wall of the installation box 3, and both ends of the center rod 31 are rotatably connected to the two fixed blocks 21 respectively. A control mechanism 6 is provided in the installation box 3 for driving the center rod 31 to rotate under the drive of the motor 521 to adjust the angle of the installation box 3.

[0039] When it is necessary to further adjust the spray angle of the nozzle 43, the staff only needs to drive the center rod 31 to rotate through the cooperation of the motor 521 and the control mechanism 6, so as to adjust the angle of the mounting box 3 fixed to the center rod 31, so that the angle of the mounting block 515 on the third connecting rod 514 and the nozzle 43 on the mounting block 515 can be further adjusted to meet the needs of different cleaning ranges.

[0040] Further, the control mechanism 6 includes a driven component 61, which includes: a second fixed plate 611, which is fixed on the inner wall of the installation box 3; a rotating shaft 612, which is rotatably installed on the second fixed plate 611; a driving wheel 613, which is fixedly sleeved on the rotating shaft 612; a second worm gear 614, which is fixed to the end of the rotating shaft 612; a second worm 615, which is arranged in the installation box 3 and meshed with the second worm gear 614; a driven wheel 616, which is fixedly sleeved on the center rod 31 and corresponds to the position of the driving wheel 613; a transmission belt 617, which is used to connect the driving wheel 613 with the driven wheel 616; the control mechanism 6 also includes a control component 62, which is arranged on the installation box 3 and is used to drive the second worm 615 to approach or move away from the second worm gear 614.

[0041] Furthermore, a clamping block 7 is fixed to the upper end of the first worm 522, and the cross-section of the clamping block 7 is rectangular. The control component 62 includes: an electric push rod 621, which is fixed to the outer wall of the installation box 3, and the output rod of the electric push rod 621 passes through the installation box 3 and is clearance-matched; a movable plate 622, one side of the movable plate 622 is fixed to the end of the output rod of the electric push rod 621; a traction rod 623, one end of the traction rod 623 is fixed to the side of the movable plate 622 away from the inner wall of the installation box 3; a connecting column 624, the upper end of the connecting column 624 is fixed to the lower end of the second worm 615, and the end of the traction rod 623 away from the movable plate 622 is fixed to the side wall of the connecting column 624, and the connecting column 624 A snap-in groove 6241 is provided at the intersection between the lower end and the side wall of the connecting column 624, and the snap-in groove 6241 is snap-fitted with the snap-in block 7 (when the snap-in groove 6241 is snap-fitted with the snap-in block 7, the second worm 615 is just meshed with the second worm wheel 614), and a position sensor (not shown in the figure) for monitoring whether the snap-in block 7 and the snap-in groove 6241 are in corresponding positions is fixed to the inner wall of the installation box 3; the guide wheel 625 is fixedly sleeved on the connecting column 624; the guide rod 626, the end of the guide rod 626 is fixed on the inner wall of the installation box 3, the guide rod 626 is slidably matched with the guide wheel 625, and two guide rods 626 are provided and symmetrically distributed on both sides of the guide wheel 625.

[0042] Combination Figure 2 , Figure 3 and Figure 5As shown, the position sensor adopts a sensor commonly used in the prior art, such as a position sensor of model NCS32100. The position sensor monitors in real time whether the position of the clamping block 7 corresponds to the clamping slot 6241, and transmits the monitoring result in the form of an electrical signal to the terminal for the staff to control the drone body 1. The electric push rod 621 adopts a commonly used electric push rod 621, such as an ALI5 electric push rod 621. The staff can control the operation of the ALI5 electric push rod 621 through the terminal. The ALI5 electric push rod 621 is connected to the terminal in communication. The specific communication connection method belongs to the prior art and does not need to be elaborated here. When it is necessary to adjust the spray angle of the nozzle 43 within a larger range, the staff only needs to control the operation of the motor 521 through the terminal so that the position of the clamping block 7 corresponds to the clamping groove 6241. At this time, the movable plate 622 and the traction rod 623 are controlled to retract by the electric push rod 621, so that the connecting column 624 and the second worm 615 are close to the clamping block 7. The guide rod 626 plays a good guiding and limiting role on the guide wheel 625, until the clamping block 7 is engaged with the clamping groove 6241, and the electric push rod 621 is closed through the terminal. At this time, after starting the motor 521, the motor 521 works The first worm 522 and the clamping block 7 at its upper end are rotated, and the clamping block 7 rotates the connecting column 624 and the second worm 615 through the clamping groove 6241, so that the second worm wheel 614, the rotating shaft 612 fixed to the second worm wheel 614 and the driving wheel 613 fixed to the rotating shaft 612 are all rotated, and under the action of the transmission belt 617, the driven wheel 616, the center rod 31 fixed to the driven wheel 616 and the installation box 3 fixed to the center rod 31 are all rotated, so that the angles of the third connecting rod 514, the installation block 515 and the nozzle 43 are further adjusted.

[0043] Furthermore, a magnetic ring 8 is fixed to the sides of the two fixing blocks 21 that are close to each other, and the magnetic ring 8 can magnetically attract the side wall of the installation box 3. Figure 3 As shown, after the electric push rod 621 is closed, the magnetic ring 8 magnetically attracts the installation box 3, which ensures the stability of the installation box 3 to a certain extent, so that the spray angle of the nozzle 43 can be adjusted within a certain range.
