Description

Technical Field

[0001] This application relates to the field of drones, and in particular to a cleaning drone system. Background Technology

[0002] After a period of use, the glass curtain walls and rooftop solar panels of buildings need to be cleaned so that they can function properly. Currently, the cleaning of glass curtain walls and rooftop solar panels is often done by cleaning workers. During the cleaning process, the cleaning workers need to be at a high position, which is extremely dangerous. Summary of the Invention

[0003] To address the technical problem of the high risks associated with manually cleaning high-altitude glass or solar panels, this application provides a cleaning drone system.

[0004] The cleaning drone system provided in this application adopts the following technical solution:

[0005] A cleaning drone system includes a drone, a water supply device, and a cleaning device; the drone has a support base at its bottom; the cleaning device includes a cleaning support mechanism, a spraying mechanism, and a wiping mechanism; the cleaning support mechanism includes an upper support frame disposed at the bottom of the support base; the spraying mechanism and the wiping mechanism are both disposed on the upper support frame; the spraying mechanism is used to spray water mist onto the cleaning location; the wiping mechanism is used to wipe the cleaning location sprayed with water mist; and the water supply device is used to supply water to the spraying mechanism.

[0006] By adopting the above technical solution, unmanned scaffolding can replace cleaning personnel to reach high altitudes. First, a spraying mechanism sprays water mist onto the cleaning area, and then a wiping mechanism wipes the area sprayed with water mist. This avoids manual work at high altitudes and improves safety.

[0007] Optionally, the spraying mechanism includes a pair of spray support plates disposed on the upper support frame, a spray frame disposed between the lower parts of the pair of spray support plates, a spray rod disposed on the spray frame, an atomizing nozzle disposed at the end of the spray rod away from the drone, and a connecting hose disposed at the end of the spray rod near the drone; the pair of spray support plates are located on both sides of the upper support frame; the water supply device is detachably connected to the end of the connecting hose away from the spray rod.

[0008] By adopting the above technical solution, the water supply device supplies water to the spray bar through the connecting hose, and finally sprays water mist from the atomizing nozzle to the cleaning position. This makes the atomizing nozzle close to the cleaning position, so that the water mist can come into more complete contact with the cleaning position, thereby improving the subsequent cleaning efficiency.

[0009] Optionally, the spray frame is rotatably connected between a pair of spray support plates; a spray angle adjustment component is provided between the pair of spray support plates; the spray angle adjustment component is used to drive the spray frame to rotate.

[0010] By adopting the above technical solution, the spray angle adjustment component drives the spray frame to rotate, thereby changing the direction of the spray bar on the spray frame, that is, the direction of water output from the atomizing nozzle, so as to adapt to cleaning positions with different tilt angles, thereby making the water mist more completely contact the cleaning position, thus improving the subsequent cleaning efficiency.

[0011] Optionally, a pair of spray support plates are vertically slidably disposed on the upper support frame; the upper support frame is provided with a vertical limiting member; the vertical limiting member is used to limit the relative position between the pair of spray support plates and the upper support frame.

[0012] By adopting the above technical solution, and by adjusting the relative position between a pair of spray support plates and the upper support frame, the atomizing nozzle is positioned appropriately between itself and the drone's wings. This reduces the impact of wind generated by the drone's wings on the sprayed water mist and ensures that the atomizing nozzle and the wiping mechanism are in a suitable position, minimizing the impact between spraying and wiping, thereby improving cleaning efficiency.

[0013] Optionally, the scrubbing mechanism includes a pair of scrubbing support plates, a scrubbing base plate disposed between the pair of scrubbing support plates, and a scrubbing assembly disposed on the upper surface of the scrubbing base plate; the scrubbing assembly includes a scrubbing cloth connected end to end, a scrubbing cloth support member disposed on the upper surface of the scrubbing base plate for covering the scrubbing cloth, and a scrubbing drive member for driving the scrubbing cloth to move around the scrubbing cloth support member.

[0014] By adopting the above technical solution, during wiping, the wiping drive moves the wiping cloth. Since the wiping cloth is connected end to end, a clean wiping cloth can wipe a larger area, thereby reducing the frequency of changing and cleaning the wiping cloth, thus improving the cleaning efficiency.

[0015] Optionally, the wiping cloth support includes a pair of outer support frames elastically movable on the upper end face of the wiping base plate, a pair of inner support frames elastically movable on the upper end face of the wiping base plate, and a pair of rotating rollers rotatably connected to the upper end face of the wiping base plate; the wiping drive is used to drive one of the rotating rollers to rotate; the moving directions of the pair of outer support frames and the pair of inner support frames are respectively perpendicular to the upper support frame; an outer support roller is rotatably connected to the end of the outer support frame away from the upper support frame; an inner support roller is rotatably connected to the end of the inner support frame away from the upper support frame; the pair of outer support rollers are parallel to the upper support frame. The pair of rotating rollers are distributed along a direction parallel to the pair of upper support frames; the pair of inner support rollers are distributed along a direction parallel to the pair of upper support frames; the pair of inner support rollers are located between the pair of outer support rollers and the pair of rotating rollers; the pair of outer support rollers are located on the side of the pair of rotating rollers away from the upper support frames; the wiping cloth is sleeved on the pair of rotating rollers and the pair of outer support rollers, and the pair of inner support rollers abut against the wiping cloth; the wiping cloth is in the shape of a "U" with its opening facing the upper support frames, and the portion of the wiping cloth between the pair of outer support rollers is located on the side of the wiping base plate away from the upper support frames.

[0016] By adopting the above technical solution, a pair of inner support frames and a pair of outer support frames are elastically movable, so that the wiping cloth is in a taut state, and at the same time the wiping cloth is elastically positioned with respect to the cleaning position. In this way, the wiping cloth can perform its function without damaging the cleaning position. The wiping cloth between the pair of outer support rollers is located on the side of the wiping base plate away from the upper support frame, so that the wiping base plate is prevented from accidentally hitting the cleaning position during the wiping process, thus avoiding damage to both.

[0017] Optionally, a pair of the scrubbing support plates are rotatably connected to a pair of opposite end faces of the upper support frame; a scrubbing angle adjusting member is provided on a pair of opposite end faces of the upper support frame; the scrubbing angle adjusting member corresponds one-to-one with the scrubbing support plate and is used to drive the scrubbing support plate on the corresponding side to rotate.

[0018] By adopting the above technical solution, the angle of a pair of wiping support plates, i.e. the angle of the wiping cloth, can be adjusted by the wiping angle adjustment component, so that different cleaning positions on different inclined surfaces can be cleaned, and the range of applications is wider.

[0019] Optionally, the scrubbing base plate is movably disposed between the end faces of the pair of scrubbing support plates that are close to each other; the scrubbing support plates are provided with translation drive components; the pair of translation drive components are used to drive the scrubbing base plate to move.

[0020] By adopting the above technical solution, the translation drive component drives the cleaning base plate to move horizontally, which can control the distance between the drone and the cleaning position, thereby avoiding damage caused by the drone colliding with the cleaning position.

[0021] Optionally, the water supply device includes an electrolysis water mechanism and a water storage tank mechanism; the electrolysis water mechanism is installed on the ground; the electrolysis water mechanism is used to generate neutral anolyte water rich in hydroxyl radicals and fill the water storage tank mechanism with the anolyte water; the water storage tank mechanism is installed at the bottom of the support base and is used to supply anolyte water to the spray mechanism.

[0022] By adopting the above technical solution, the neutral anolyte electrolyzed water rich in hydroxyl radicals generated by the water electrolysis mechanism is filled into the water storage tank mechanism. Then, the drone carries the water storage tank mechanism into the air. The water storage tank mechanism inputs the anolyte electrolyzed water inside into the spray mechanism and sprays it out from the spray mechanism. This makes the drone's range wider, and at the same time, the neutral anolyte electrolyzed water rich in hydroxyl radicals improves the cleaning ability, thereby improving cleaning efficiency and saving water resources.

[0023] Optionally, the water supply device includes an electrolysis mechanism and a water supply hose; the electrolysis mechanism is installed on the ground; the water supply hose is used to connect the electrolysis mechanism and the spray mechanism; the electrolysis mechanism is used to generate neutral anolyte water rich in hydroxyl radicals and supply the anolyte water to the spray mechanism through the water supply hose.

[0024] By adopting the above technical solution, the water electrolysis mechanism generates neutral anodic electrolyzed water rich in hydroxyl radicals, which reaches the spray mechanism through the water supply hose and is finally sprayed out from the spray mechanism. In this way, the drone can always operate at high altitude, thereby improving cleaning efficiency. At the same time, the neutral anodic electrolyzed water rich in hydroxyl radicals improves the cleaning ability, thus saving water resources.

[0025] In summary, the beneficial effects of this application are as follows:

[0026] 1. Drones replace cleaning personnel, avoiding the need for manual labor at high altitudes and improving safety.

[0027] 2. Improve cleaning efficiency and save water resources. Attached Figure Description

[0063] The working principle of a cleaning drone system in Example 1:

[0064] First, the water electrolysis mechanism 70 starts working, generating neutral anolyte water rich in hydroxyl radicals in the anode chamber 711. Then, the horizontal part of the upper side of the outlet pipe 78 is fitted onto the end of the water inlet pipe 22 of the storage tank. The valve on the outlet pipe 78 then opens, and the solenoid valve 23 on the water inlet pipe 22 of the storage tank opens. Next, the water pump 79 starts, and the anolyte water in the anode chamber 711 enters the storage tank 21 through the outlet pipe 78, thus replenishing the storage tank 21. Then, the drone 10 takes off and reaches the cleaning position. The spray angle adjustment cylinder 57 drives the spray frame 53 to swing to the appropriate position, and then the connecting valve 26 opens, and the spray air pump pumps gas into the storage tank 21. This allows the anolyte water in the storage tank 21 to enter the spray bar 54, ultimately being atomized and sprayed. Water mist is sprayed from point 56, which, when sprayed onto the cleaning area, can quickly and effectively degrade CO, NOx, and other complex organic components in the smog. This water mist, rich in hydroxyl radicals, degrades organic pollutants in the cleaning area and reduces the adhesion of dirt. When the water in the storage tank 21 is depleted, water is replenished according to the above principle. Then, a pair of wiping angle adjustment cylinders 62 drive a pair of wiping support plates 61 to swing until they reach the tilt angle that matches the cleaning area. Then, a pair of translation drive cylinders 63 drive the wiping base plate 64 away from the storage tank 21 until the end of the wiping cloth 66 away from the upper support frame 43 contacts the cleaning area. Then, the wiping drive motor 65 drives the rotating roller 68 to rotate, thereby moving the wiping cloth 66 to wipe the cleaning area sprayed with anodic electrolytic water mist.

[0065] Example 2: Reference Figure 8 The difference between Embodiment 2 and Embodiment 1 is that the water supply device includes an electrolysis water mechanism 70 and a water supply hose 80; the structure of the electrolysis water mechanism 70 in Embodiment 2 is the same as that in Embodiment 1; one end of the water supply hose 80 is screwed to the water outlet end on the upper side of the water outlet pipe 78, and the other end is screwed to the hose connector of the connecting hose 55 away from the spray bar 54; during operation, the water pump 79 pumps the anode electrolyzed water in the anode chamber 711 into the water supply hose 80, and the anode electrolyzed water enters the spray bar 54 along the water supply hose 80, and finally sprays water mist from the atomizing nozzle 56.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
