DETAILED DESCRIPTION

[0046] The embodiments of the utility model will be described below in conjunction with the accompanying drawings. Figure 1 to the accompanying drawings Figure 6 The technical solutions in the embodiments of the utility model are clearly and completely described, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0047] It should be noted that if the direction in the embodiments of the utility model is shown in the drawings, if a certain specific posture changes, the directional indication also changes accordingly.

[0048] The unmanned aerial vehicle for cleaning operation can quickly perform cleaning operation in a large area, which is not limited by terrain, obstacles and other factors. Therefore, it is widely used in high-altitude cleaning and other fields.

[0049] However, the unmanned aerial vehicle with cleaning operation function in the prior art has a fixed water outlet angle, and when facing the situation that the object with a complex surface needs to be cleaned, it is usually necessary to frequently adjust the flight position and flight angle of the unmanned aerial vehicle, which increases the difficulty of operating the unmanned aerial vehicle.

[0050] To this end, the present application provides an adjustable angle cleaning device, which can adjust the water outlet angle to cope with various complex cleaning environments.

[0051] The adjustable angle cleaning device can be directly or indirectly arranged on the unmanned aerial vehicle by welding or bolt fixing and the like. In some specific application scenarios, the adjustable angle cleaning device is arranged below the unmanned aerial vehicle to adjust the water outlet angle for cleaning the unmanned aerial vehicle.

[0052] Specifically, as shown in the figure, Figure 1 The adjustable angle cleaning device comprises a cleaning member 1, a swinging member 2 connected with the cleaning member 1, a driving member 3 for providing driving force for the swinging member, and a transmission member 4.

[0053] As shown in the figure, Figure 2 The cleaning member 1 comprises a spray head 11 and a water conveying pipeline 12, and is used for spraying water to the surface of an object to be cleaned. One end of the water conveying pipeline 12 is arranged in fixed connection with the unmanned aerial vehicle, and the other end of the water conveying pipeline 12 is provided with the spray head 11, which is used for spraying water in the water conveying pipeline 12 to the surface of the object to be cleaned.

[0054] The region of the water conveying pipeline 12 close to the spray head 11 is fixed on the swinging member 2. The swinging member 2 is connected with the driving member 3 through the transmission member 4.

[0055] When the driving member 3 works, the driving member 3 drives the transmission member 4 to move, so that the swinging member 2 swings, and the water conveying pipeline 12 fixed on the swinging member 2 also swings. Therefore, when the water conveying pipeline 12 swings, the spray head 11 swings, and the swing angle of the spray head 11 can be set to left-right swing, front-back swing or 360-degree rotation according to actual use requirements.

[0056] In an embodiment, when the spray head 11 swings left and right with a certain fixed point as the center, the water spraying angle changes with the change of the swing angle of the spray head 11 in the process of swinging. Moreover, the swing angle of the spray head 11 determines the range of change of the water spraying angle. The greater the swing angle of the spray head, the greater the range of change of the water spraying angle, and the larger the area that can be covered. For example, in this embodiment, the swing angle of the spray head 11 is ±45°, so the water spraying angle changes within a range of ±45° left and right with the vertical direction as the center.

[0057] In use, as shown in the figure, Figure 3As shown, one end of the transmission member 4 is in transmission connection with the driving member 3, and the other end of the transmission member 4 is pivoted with the swinging member 2, and the transmission member 4 is used to transmit the driving force provided by the driving member 3 to the swinging member 2 so as to make the swinging member 2 swing.

[0058] Therefore, the adjustable angle cleaning device can make the water in the cleaning member 1 act on the surface of the object to be cleaned at a certain spray angle, and the swing angle can be adjusted to adjust the cleaning area according to the actual use requirement.

[0059] In a specific embodiment, the driving member 3 is arranged in an assembly box 6. The assembly box 6 is a rectangular solid structure, and the assembly box 6 is arranged on the cleaning unmanned aerial vehicle and the interior of the assembly box 6 is hollow to assemble the driving member 3. The assembly box 6 is usually made of hard material, such as metal, to protect the driving member 3 arranged in the interior from being damaged by collision.

[0060] In the embodiment, the driving member 3 includes a motor 31 and a power output shaft 32 electrically connected with the motor 31, and the motor 31 and part of the power output shaft 32 are arranged in the assembly box 6. The outer surface of the assembly box 6 has a through hole for connecting the interior of the assembly box 6 with the outside. The end of the power output shaft 32 is exposed from the through hole.

[0061] In an embodiment of the utility model, as shown in Figure 3 As shown, the power output shaft 32 is pivoted with the transmission member 4. In detail, the transmission member 4 includes a transmission rod 41, and the two ends of the transmission rod 41 are respectively provided with a first rotary joint 42 and a second rotary joint 43. The first rotary joint 42 is pivoted on the swinging member 2, and the second rotary joint 43 is pivoted with the power output shaft 32.

[0062] Therefore, when the motor 31 works, the power output shaft 32 drives the second rotary joint 43 to rotate, and according to the force transmission, the transmission rod 41 and the first rotary joint 42 also rotate in the same direction as the power output shaft 32. Under the action of the driving member 3, the second rotary joint 43 rotates around the power output shaft 32 as the center, and the rotation distance of the second rotary joint 43 is converted into the moving distance of the transmission rod 41 in the transverse direction, so that the first rotary joint 42 at the other end of the transmission rod 41 moves in the transverse direction, thereby causing the swing member 2 pivoted to the first rotary joint 42 to swing.

[0063] In an embodiment of the utility model, as shown in Figure 3 and Figure 4 The power output shaft 32 is connected with an output swing piece 33; the output swing piece 33 is pivoted with the transmission member 4. The output swing piece 33 is pivoted with the second rotary joint 43; when the driving member 3 works, the output swing piece 33 drives the second rotary joint 43 to relatively move around the axis of the power output shaft.

[0064] When the motor 31 works, the motor 31 drives the power output shaft 32 to rotate. When the power output shaft 32 rotates, the output swing piece 33 arranged on the outer periphery of the power output shaft 32 also rotates. The output swing piece 33 drives the second rotary joint 43 pivoted thereto to relatively move around the axis of the connecting portion 331. As described above, the rotation distance of the second rotary joint 43 is converted into the moving distance of the transmission rod 41 in the transverse direction, so that the first rotary joint 42 at the other end of the transmission rod 41 moves in the transverse direction, thereby causing the swing member 2 pivoted to the first rotary joint 42 to swing.

[0065] Further, as shown in Figure 4 In order to make the angle adjustment of the adjustable angle cleaning device adapt to various use scenarios, the output swing piece 33 has a plurality of adjusting portions 331; each adjusting portion 331 has a distance d1 from the power output shaft.

[0066] It should be noted that the adjusting part 331 is a through hole arranged on the output swing piece 33, and the second rotary joint 43 is pivoted in the adjusting part 331 according to actual needs, because the distance from each adjusting part 331 to the power output shaft 32 is different. Therefore, the circumference of a circle is calculated by the formula C=2πd, so the greater the distance d1 is, the longer the C is, and the greater the torque generated by the second rotary joint 43 around the power output shaft 32 as the center is, thereby being able to increase the moving distance of the transmission rod 41 in the transverse direction, and indirectly realizing the increase of the swing angle of the swing member 2. Conversely, when the distance d1 is smaller, the C is smaller, and the torque generated by the second rotary joint 43 around the power output shaft 32 as the center is smaller, thereby being able to reduce the moving distance of the transmission rod 41 in the transverse direction, and indirectly realizing the reduction of the swing angle of the swing member 2.

[0067] In another embodiment of the utility model, as shown in Figure 4 and Figure 5 The transmission rod 41 comprises a first part 411 and a second part 412; the first part 411 and the second part 412 have an adjusting member 44 therebetween; the adjusting member 44 comprises a first adjusting piece 441 and a second adjusting piece 442; one end of the first adjusting piece 441 is connected to the first part 411, and the other end of the first adjusting piece 441 is connected to the second part 412; the second adjusting piece 442 is sleeved on the first adjusting piece 441 to adjust the distance d2 between the first part 411 and the second part 412.

[0068] It should be understood that in the embodiment, the first adjusting piece 441 is a screw rod, and the second adjusting piece is a nut. When one of the second adjusting pieces 442 rotates outward in a positive direction as a driving piece, due to the action of the helix, the first adjusting piece 441 moves linearly along the axial direction of the helix, and the first adjusting piece 441 drives the second part 412 to move in the direction of the first part 411 to shorten the distance between the first part 411 and the second part 412 when moving linearly. Conversely, when the second adjusting piece 442 rotates in the opposite direction, the first adjusting piece 441 drives the second part 412 to move in the direction away from the first part 411 to increase the distance between the first part 411 and the second part 412 when moving linearly. Such a design can realize the transverse adjustment of the distance between the two parts, that is, the adjustment of the distance d2 between the first part 411 and the second part 412. Further, the distance d2 between the first rotary joint 42 and the second rotary joint 43 located at the two ends of the transmission rod 41 is adjusted, thereby realizing the adjustment of the swing amplitude of the swing member 2.

[0069] Further, the swinging member 2 comprises a swing shaft 21, one end of which is pivotally connected with a part where the cleaning unmanned aerial vehicle can be installed, and the other end of which has a fixing part 211; the fixing part is used for fixing the water delivery pipe 12 of the cleaning member 1.

[0070] In an embodiment of the utility model, one end of the swing shaft 21 is connected with the assembly box 6, the assembly box 6 has a through hole, and a fixing shaft is arranged in the through hole and pivotally connected with the swing shaft.

[0071] In some other use scenarios, the swing shaft 21 can also be arranged on the unmanned aerial vehicle body according to actual use needs.

[0072] In the embodiment, since the second rotary joint 42 is pivotally connected with the swing shaft 21, when the transmission member 4 moves, the swing shaft 21 swings around the fixing shaft under the action of the transmission rod 41, and the water in the water delivery pipe 12 connected with the swing shaft 21 is sprayed at a certain angle.

[0073] Since the water in the water delivery pipe 12 has a reaction force when being sprayed, the area near the water outlet end of the water delivery pipe 12 shakes unnecessarily, and the spray head 11 cannot stably swing and spray water at the angle and track set in advance.

[0074] Therefore, in an embodiment of the utility model, as shown in Figure 5 The fixing part 211 is covered by a positioning member 5 to constrain the water outlet end of the water delivery pipe 12 at the end of the swing shaft 21.

[0075] It should be understood that, in this way, the area near the water outlet end of the water delivery pipe 12 can be kept stable, so that the spray head 11 cannot stably swing and spray water at the angle and track set in advance, and the accuracy and uniformity of water spraying are ensured.

[0076] In an embodiment of the utility model, the spray head 11 is detachably connected with the water delivery pipe 12. It should be understood that, in this way, different spray heads 11 can be replaced according to actual use needs. The water outlet of the spray head 11 has various shapes, such as a circular shape, or an elongated shape or a square shape, etc. in actual use. Different shapes of the water outlet affect the water spraying amount and the spraying angle. It should be further explained that the spray head 11 and the water delivery pipe 12 can be detachably connected in a screwing or buckling manner.

[0077] In addition, an unmanned aerial vehicle is also provided, as shown in Figure 6The unmanned aerial vehicle body 100 and the adjustable angle cleaning device 200 are shown.

[0078] The unmanned aerial vehicle can flexibly change the water outlet angle according to the actual environment and task requirements, for example, in agricultural irrigation, the angle is adjusted to achieve uniform irrigation according to different terrains and crop distribution.

[0079] In summary, the adjustable angle cleaning device is assembled on the unmanned aerial vehicle, and the water outlet angle of the cleaning device can be adjusted according to the actual use to reduce the difficulty of adjusting the position of the unmanned aerial vehicle and the difficulty of operating the unmanned aerial vehicle when the unmanned aerial vehicle cleans objects with complex surfaces.

Therefore, the present application is not limited to the specific embodiments disclosed and described above, and some modifications and changes of the present application should fall within the protection scope of the claims of the present application.
