Description

Technical Field

[0001] This application relates to the field of high-altitude cleaning operations, and in particular to a high-altitude, high-efficiency, and stable cleaning device and its nozzle. Background Technology

[0002] Outdoor walls and billboards require regular cleaning. Traditional "spider-man" rope work heavily relies on workers' skills and physical strength, is greatly affected by weather and psychological factors, and carries a high risk of falls, making it an extremely high-risk profession. Young people are increasingly unwilling to engage in such high-risk jobs, leading to a labor shortage. Furthermore, the preparation work before cleaning operations is cumbersome (such as setting up baskets and anchor points), the working area is small, movement is slow, and cleaning efficiency is low.

[0003] Products based on drone platforms equipped with water purification devices have appeared on the market. These products are usually composed of aircraft bodies, spray guns, water supply pipes, pump bodies, etc. The aircraft bodies spray the spray guns, the water inlet of the spray guns is connected to the water supply pipes, the other end of the water supply pipes extends to the ground to connect to cleaning fluid or water, and the pump body is connected to the water supply pipes. The pump body drives the cleaning fluid or water into the water supply pipes.

[0004] However, the actual performance of these products is not ideal. The main problem is that the nozzles are high-pressure nozzles that spray directly, which have a small water output range, resulting in a limited cleaning coverage area and a small effective area per operation. This requires the drone to move frequently, increasing the difficulty and time cost of operation. Therefore, further improvements are needed. Summary of the Invention

[0005] To address the issue of limited effective area in a single operation of drone cleaning equipment, this application provides a high-altitude, high-efficiency, and stable cleaning device and its nozzle.

[0006] Firstly, the nozzle provided in this application adopts the following technical solution:

[0007] The nozzle includes a mounting housing, a connecting pipe, a nozzle, and a flexible hose. One end of the flexible hose is connected to a water supply pipe, and the other end is connected to a connecting pipe. The end of the connecting pipe away from the flexible hose is connected to the nozzle. The flexible hose is disposed inside the mounting housing. One end of the mounting housing has a swing groove. The middle part of the connecting pipe is located in the swing groove, and the connecting pipe is horizontal. The nozzle also includes a drive mechanism that drives the end of the connecting pipe located inside the mounting housing to swing back and forth. The two ends of the connecting pipe that are far apart from each other swing back and forth with the swing groove as a fulcrum.

[0008] By adopting the above technical solution, the drive mechanism drives the connecting pipe to swing back and forth, thereby causing the nozzle to swing back and forth as well. This allows the water jet to automatically scan the impact point on the wall horizontally, covering a strip-shaped area (the width depends on the swing amplitude) with a single hover. Previously, drones could only achieve "line" cleaning by moving a certain distance, but this application upgrades the drone's movement to "area" cleaning, significantly increasing the single-point operation area and thus improving cleaning efficiency. For the same area, the drone's movement path is reduced, decreasing the difficulty and time cost of drone operation.

[0009] Optionally, the connecting pipe is provided with a swing ball, the swing ball is provided with a through hole for the connecting pipe to pass through, the swing ball is rotatably disposed on the inner wall of the swing groove, the inner wall of the swing groove is an arc surface that fits with the outer wall of the swing ball, and the rotation axis of the swing ball is vertical.

[0010] By adopting the above technical solution, the oscillating ball acts as a spherical bearing or rotating joint. A connecting pipe passes through it, and during oscillation, the oscillating ball rotates within the groove, rather than the connecting pipe sliding on the groove wall, thus optimizing the operation. The oscillating ball evenly transmits force to the oscillating groove of the mounting housing through a large-area contact, avoiding stress concentration, significantly extending the service life of key moving parts, reducing maintenance, and achieving stable, reliable, and long-life oscillation. The oscillating ball can be made of wear-resistant ceramic or stainless steel and can be replaced individually.

[0011] Optionally, the outer wall of the swing ball is rotatably connected to the inner wall of the swing groove via a rotating shaft, wherein the rotating shaft is vertical.

[0012] By adopting the above technical solution, although the rotational resistance of the spherical friction pair with "spherical fit" is smaller than that of direct sliding of the connecting pipe, it still has the defects of being unpredictable and unstable. The frictional torque will change due to sealing pressure, wear, and the ingress of dirt, resulting in load fluctuations in the drive mechanism and uneven swing speed. The vertical rotation axis determines the only physical axis of rotation for the swing ball, and the "fit" between the spherical surface and the groove wall at this time becomes mainly for sealing and auxiliary limiting, rather than the main torsion bearing. This significantly reduces the rotational resistance of the swing ball, making it stable and predictable. It also allows for the use of a smaller drive motor with lower power and weight, reducing the burden on the drone.

[0013] Optionally, the driving mechanism includes a sliding frame slidably disposed within the mounting housing, the sliding frame being located above or below the connecting pipe, a limit frame being provided on the sliding frame, and the connecting pipe being located within the limit frame; a driving groove is provided in the middle of the sliding frame, and first toothed surfaces are provided on the upper and lower side walls of the driving groove; a turntable is rotatably disposed within the driving groove, the turntable being located directly above or below the connecting pipe, and a second toothed surface is provided at one end of the outer periphery of the turntable, the second toothed surface alternately meshing with two first toothed surfaces;

[0014] When the second tooth surface engages with the upper first tooth surface, the turntable rotates and drives the sliding frame to slide in the first direction; when the second tooth surface disengages from the upper first tooth surface, the sliding frame stops; the turntable continues to rotate, causing the second tooth surface to engage with the lower first tooth surface and driving the sliding frame to slide in the second direction, the first direction and the second direction being opposite; the limiting frame limits the connecting pipe and causes the connecting pipe to swing left and right around the swing groove as a fulcrum; the driving mechanism also includes a driving component that drives the turntable to rotate.

[0015] By adopting the above technical solution, the drive component drives the turntable to rotate continuously, which is automatically converted into a stable and reliable linear reciprocating motion of the sliding frame, thereby driving the nozzle to swing left and right. During rotation, the second toothed surface on the edge of the turntable alternately meshes with the upper and lower first toothed surfaces of the drive groove. This cycle repeats, causing the sliding frame to automatically and regularly perform linear reciprocating motion between the two ends. Since the middle of the connecting pipe is defined as a fulcrum by the swing groove, the left-right pushing motion at its end is converted into a left-right fan-shaped swing of the nozzle end around this fulcrum. Furthermore, a smaller amplitude of wobbling at the end of the connecting pipe inside the mounting housing allows the swing groove to be positioned closer to the limit frame between the nozzle and the limit frame, thus achieving a larger amplitude of nozzle wobbling. This results in a compact drive mechanism with a small size, allowing for a larger nozzle wobbling amplitude even with a small sliding frame amplitude, thereby increasing the cleaning area.

[0016] The turntable is located directly above or below the connecting pipe, and the sliding frame has an axisymmetric structure, ensuring even nozzle mass and preventing unilateral imbalance that could affect drone flight stability. Furthermore, the drive mechanism is simple in structure, with small components, a small footprint, and low weight, making it suitable for lightweight drone flight and contributing to stable high-altitude flight.

[0017] Optionally, the driving component is a motor, the motor shaft of which is coaxially connected to the turntable via an extension shaft, and the motor is fixed inside the mounting housing.

[0018] By adopting the above technical solution, since the turntable rotates continuously, a small-sized, low-power motor can be used as the driving component, reducing the drone's weight. By setting an extension shaft, the motor's mounting position is moved away from the nozzle. Due to the longer nozzle design, the motor can be mounted closer to the drone, bringing the nozzle's overall center of gravity closer to the drone, facilitating stable flight. Simultaneously, the vibration from the motor's operation will not cause the nozzle to wobble, ensuring nozzle stability.

[0019] Optionally, a stabilizing frame is provided inside the mounting housing, and the middle part of the extension shaft is rotatably connected to the stabilizing frame via a bearing.

[0020] By adopting the above technical solution, the stabilizer provides stable support for a longer extended cycle.

[0021] Optionally, it also includes a supporting outer tube and a mounting base. The mounting base has a mounting cavity and a water supply pipe connector on its side wall. The supporting outer tube is fixedly connected to the mounting base and the mounting shell. The flexible hose extends sequentially into the mounting shell, the supporting outer tube, and the mounting base and connects to the inner end of the water supply pipe connector. The outer end of the water supply pipe connector is used for water supply pipe connection. The portion of the flexible hose located inside the mounting shell is loosely arranged. The mounting base is used for mounting on a drone.

[0022] By adopting the above technical solution, the supporting outer tube serves as a rigid frame, firmly connecting the front functional core (mounting shell, nozzle, drive mechanism) to the rear mounting base into a single unit. It withstands all aerodynamic loads, inertial forces, and water flow backlash during cleaning operations, preventing structural flutter or deformation. The mounting base is used to store and secure the piping, and allows for convenient, safe, and reliable installation at the UAV mounting point. This makes the nozzle a robust, integrated external pod capable of withstanding vibrations and impacts during flight and operation, ensuring long-term operational reliability.

[0023] The hose is partially slack within the mounting housing, allowing the connecting pipe and hose to swing. The slack hose has an allowance to accommodate the swinging of the connecting pipe.

[0024] Optionally, a battery is provided inside the mounting base, the battery is electrically connected to the motor, a charging interface and a switch are provided on the mounting base, the charging interface is electrically connected to the battery and the switch, and the power cable connecting the battery and the motor extends along the inner cavity of the support tube into the mounting housing to connect to the motor.

[0025] By adopting the above technical solution, the motor is located inside the mounting housing, and the supporting outer tube connects the mounting housing and the mounting base. The mounting base is installed on the drone, ensuring a certain distance between the motor and the drone, so that the magnetic field during motor startup will not interfere with the drone's flight. The supporting outer tube protects the internal flexible hose and also protects the motor's power cord. The battery is relatively heavy, necessitating its installation within the mounting base to ensure the drone's stability and flight. The motor has low power, and the battery can meet the motor's power requirements during cleaning. Furthermore, the motor switch is manually turned on before drone takeoff, simplifying the motor circuitry.

[0026] Secondly, this application provides a high-altitude, high-efficiency, and stable cleaning device, which adopts the following technical solution:

[0027] A high-altitude, high-efficiency, and stable cleaning device includes a drone, a pump body, and a water supply pipe, as well as a nozzle mounted on the drone. The water supply pipe is connected to the nozzle, and the other end of the water supply pipe extends to the ground for connecting cleaning fluid or water. The pump body delivers the cleaning fluid or water to the nozzle through the water supply pipe.

[0028] By adopting the above technical solution, during use, the pump body delivers water or cleaning fluid into the water supply pipe. The water or cleaning fluid then sequentially enters the water supply pipe, hose, and connecting pipe, finally being sprayed out from the nozzle. Simultaneously, the drive mechanism causes the connecting pipe to swing, making the nozzle oscillate. When the drone is hovering, this transforms traditional high-pressure water jet cleaning into fan-shaped cleaning, significantly improving efficiency. For cleaning the same area, it reduces the drone's movement path, decreasing the difficulty and time cost of drone operation.

[0029] A high-altitude, high-efficiency, and stable cleaning device includes a drone, a pump body, and a water supply pipe, as well as the aforementioned nozzle. The nozzle is mounted on the drone, and the water supply pipe is connected to the nozzle. The other end of the water supply pipe extends to the ground for connecting cleaning fluid or water. The pump body delivers the cleaning fluid or water to the nozzle through the water supply pipe.

[0030] The drone has a mounting surface at its bottom, and two sets of snap-fit ​​arms are provided on the mounting surface. A snap-fit ​​block is provided on the side of the two sets of snap-fit ​​arms that are close to each other. The outer side walls of the mounting base are provided with sliding grooves for the snap-fit ​​blocks to slide. A baffle is provided at the end of the snap-fit ​​arm away from the nozzle. The side wall of the baffle facing the nozzle is used to abut against the mounting base.

[0031] By adopting the above technical solution, the two sets of snap-fit ​​arms, snap-fit ​​blocks, and sliding grooves enable quick assembly and disassembly of the drone and the mounting base. During nozzle flushing operations, the nozzle as a whole is subjected to a force away from the flushing surface, and the baffle prevents the mounting base from sliding away from the flushing surface between the snap-fit ​​arms.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. The proposed solution upgrades the cleaning process from moving the drone a certain distance to cleaning the "area", which multiplies the single-point operation area, thereby improving cleaning efficiency. Cleaning the same area reduces the drone's movement path, reducing the difficulty and time cost of drone operation.

[0034] 2. The design of the swing ball and rotating shaft significantly extends the service life of key moving parts, reduces maintenance, and thus achieves stable, reliable, and long-life swing motion;

[0035] 3. The drive mechanism has a compact structure and small size. Even with a small sliding range of the sliding frame, it can achieve a large oscillation range of the nozzle, thereby increasing the cleaning area.

[0036] 4. The design of two sets of snap-fit ​​arms, snap-fit ​​blocks, and slides enables quick assembly and disassembly of the drone and the mounting base. The baffle prevents the mounting base from sliding away from the rinsing surface between the snap-fit ​​arms. Attached Figure Description

[0045] The present application will be further described in detail below with reference to the accompanying drawings.

[0046] This application discloses a nozzle. (Refer to...) Figure 1 , Figure 2 The nozzle includes a mounting housing 1, a connecting pipe 2, a nozzle 3, a hose 4, a supporting outer pipe 5, and a mounting base 6. The mounting base 6 is used to mount the drone 7. One end of the supporting outer pipe 5 is fixed to the side wall of the horizontal side of the mounting base 6, and the other end is fixed to the mounting housing 1. The length direction of the supporting outer pipe 5 is horizontal. The mounting base 6 has a mounting cavity, the supporting outer pipe 5 is hollow, and the mounting housing 1 also has a cavity. The inner cavities of the mounting base 6, the supporting outer pipe 5, and the mounting housing 1 are connected in sequence.

[0047] Reference Figure 1 , Figure 2 The mounting base 6 is connected to a water supply pipe connector 61 on the side wall away from the supporting outer tube 5. The hose 4 extends sequentially into the mounting shell 1, the supporting outer tube 5 and the mounting base 6 and connects to the inner end of the water supply pipe connector 61 located in the mounting cavity. The outer end of the water supply pipe connector 61 is connected to the water supply pipe 10.

[0048] Reference Figure 3 One end of the hose 4 is connected to the water supply pipe 10 via the water supply pipe connector 61, and the other end is connected to the connecting pipe 2. The end of the connecting pipe 2 away from the hose 4 is connected to the nozzle 3. The end of the mounting shell 1 away from the supporting outer pipe 5 is provided with a swing groove 11, and the middle part of the connecting pipe 2 is located in the swing groove 11. The length direction of the connecting pipe 2 is horizontal.

[0049] Reference Figure 2 , Figure 3 A swing ball 21 is fixed in the middle of the connecting pipe 2. The swing ball 21 has a through hole 211 for the connecting pipe 2 to pass through. The outer wall of the connecting pipe 2 is fixed to the inner wall of the through hole 211. The swing ball 21 is rotatably mounted on the inner wall of the swing groove 11, the inner wall of which is an arc surface that fits with the outer wall of the swing ball 21. The rotation axis 212 of the swing ball 21 is vertical. Rotation shafts 212 are fixed at the top and bottom of the outer wall of the swing ball 21, and the axis of the rotation shafts 212 is vertical.

[0050] Reference Figure 3 , Figure 4 The nozzle also includes a drive mechanism 8 that drives the end of the connecting pipe 2 located inside the mounting housing 1 to swing back and forth. The two ends of the connecting pipe 2 that are far apart from each other swing back and forth with the swing groove 11 as the fulcrum.

[0051] Reference Figure 4 The drive mechanism 8 includes a sliding frame 81 slidably disposed within the mounting housing 1. The sliding frame 81 is located above or below the connecting pipe 2; in this embodiment, the sliding frame 81 is located directly above the connecting pipe 2. A limiting frame 811 is fixed to the bottom of the sliding frame 81. The connecting pipe 2 is located within the limiting frame 811, and the outer wall of the connecting pipe 2 slides in contact with the limiting frame 811, allowing the outer wall of the connecting pipe 2 to swing within the limiting frame 811. The limiting frame 811 limits the connecting pipe 2 and allows the connecting pipe 2 to swing left and right around the swing groove 11 as a fulcrum.

[0052] Reference Figure 4 A stabilizing plate 82 is fixed inside the mounting housing 1. The stabilizing plate 82 has a stabilizing groove 821 for the sliding frame 81 to slide back and forth. The sliding direction of the sliding frame 81 is horizontal and perpendicular to the length direction of the supporting outer tube 5. The sliding frame 81 is slidably connected within the stabilizing groove 821. A driving groove 812 is provided in the middle of the sliding frame 81, and both the upper and lower side walls of the driving groove 812 are provided with first toothed surfaces 813.

[0053] A turntable 83 is rotatably mounted within the drive slot 812. The turntable 83 is rotatably connected to the stabilizing plate 82. The turntable 83 is located directly above or below the connecting pipe 2. In this embodiment, the turntable 83 is located directly above the connecting pipe 2. The axis of the turntable 83 is parallel to the length direction of the outer support pipe, and the axis of the turntable 83 is directly above the axis of the supporting outer pipe 5. One end of the outer periphery of the turntable 83 is integrally formed with a second toothed surface 831. The second toothed surface 831 alternately meshes with two first toothed surfaces 813. The second toothed surfaces 831 are distributed in a fan shape on the turntable 83, and the angle of their distribution does not exceed 180 degrees.

[0054] When the second tooth surface 831 engages with the upper first tooth surface 813, the turntable 83 rotates, driving the sliding frame 81 to slide in the first direction. When the turntable 83 rotates until the second tooth surface 831 disengages from the upper first tooth surface 813, the sliding frame 81 stops. The turntable 83 continues to rotate, causing the second tooth surface 831 to engage with the lower first tooth surface 813 and driving the sliding frame 81 to slide in the second direction. The first and second directions are opposite, thus enabling the turntable 83 to continuously rotate in one direction, driving the sliding frame 81 to slide back and forth.

[0055] Reference Figure 3 , Figure 4 The drive mechanism 8 also includes a drive component 84 that drives the turntable 83 to rotate. The drive component 84 is a motor, and the motor shaft is coaxially connected to the turntable 83 via an extension shaft 86. The motor is fixed inside the mounting housing 1. A stabilizer 85 is fixed inside the mounting housing 1. An extension hole 851 is provided on the stabilizer 85, and the middle part of the extension shaft 86 is rotatably connected to the extension hole 851 via a bearing. The hose 4 is located inside the mounting housing 1, and the portion between the stabilizer 85 and the connecting pipe 2 is loosely arranged to allow for the connecting pipe 2 to swing, and the hose 4 has a reserved length.

[0056] Reference Figure 1 , Figure 4 A battery (not shown in the figure) is fixed inside the mounting base 6. The battery is electrically connected to the motor. The mounting base 6 is equipped with a charging interface 63 and a switch 64. The charging interface 63 is electrically connected to the battery and the switch 64. The switch 64 controls the connection and disconnection of the circuit, thereby controlling the start and stop of the motor. The power cable connecting the battery and the motor extends along the inner cavity of the support tube into the mounting housing 1 to connect to the motor.

[0057] The implementation principle of a nozzle in this embodiment is as follows: The nozzle is installed on a drone 7, a hose 4 is connected to a water supply pipe 10, the water supply pipe 10 is connected to a pump body 9, and the other end of the water supply pipe 10 is connected to cleaning fluid or water. Before takeoff, the switch 64 is manually turned on, and the motor rotates to drive the nozzle 3 to swing. After the drone 7 takes off and reaches the position to be cleaned, the nozzle 3 faces the surface to be cleaned, and then the pump body 9 is turned on. The pump body 9 inputs water or cleaning fluid into the water supply pipe 10, causing the nozzle to spray out to achieve cleaning. At this time, when the drone 7 moves vertically, the surface is cleaned, thereby improving the cleaning efficiency. Under the same area cleaning, the drone 7 has a smaller movement path and is easier to operate.

[0058] In this application, the connecting pipe 2 swings via the swing ball 21 and the rotating shaft 212. When the sliding bracket 81 has a small sliding amplitude, the nozzle 3 can swing larger, thereby increasing the cleaning area. Furthermore, the drive mechanism 8 is small in size and has a symmetrical bearing structure, which facilitates the balance of the drone 7 and ensures stable flight. Additionally, the center of gravity of the spray gun is close to the bottom of the drone 7, minimizing its impact on the drone 7's flight.

[0059] This application also discloses a high-altitude, high-efficiency, and stable cleaning device, referring to... Figure 2 , Figure 5 A high-altitude, efficient, and stable cleaning device includes a drone 7, a pump body 9, and a water supply pipe 10, as well as the aforementioned nozzle. The nozzle is fixed to the bottom of the drone 7 via a mounting base 6. The water supply pipe 10 is connected to the nozzle via a water supply pipe connector 61, and the other end of the water supply pipe 10 extends to the ground for connecting cleaning fluid or water. The pump body 9 delivers the cleaning fluid or water to the nozzle through the water supply pipe 10. The pump body 9 can be a water pump or a cleaning machine, both serving to pump water or cleaning fluid into the water supply pipe 10. The cleaning fluid and water are typically stored in a container, and the end of the water supply pipe 10 furthest from the drone 7 is placed into the container for use.

[0060] Reference Figure 2 , Figure 6 , Figure 7 The drone 7 has a horizontal mounting surface at its bottom, on which two sets of parallel snap-fit ​​arms 71 are fixed. The length direction of the snap-fit ​​arms 71 is parallel to the length direction of the supporting outer tube 5. A snap-fit ​​block 72 is fixed on the side of the two sets of snap-fit ​​arms 71 that are close to each other. The mounting base 6 has sliding grooves 65 on both sides for the snap-fit ​​blocks 72 to slide, and the length direction of the sliding grooves 65 is parallel to the length direction of the supporting outer tube 5. A baffle plate 73 is fixed to the end of the snap-fit ​​arm 71 away from the nozzle 3. When the mounting base 6 is snapped between the two snap-fit ​​arms 71, the baffle plate 73 abuts against the side wall of the nozzle 3. When the mounting base 6 is connected to the drone 7, the mounting base 6 is inserted from the connecting arm away from the baffle plate 73. The snap-fit ​​arms 71 are elastic, thereby snapping and fixing the mounting base 6 in place, and the mounting base 6 is not easy to detach from the snap-fit ​​arms 71.
