[0033] The following is combined with Figure 1 -Attached Figure 12 , further details of this application are given.

[0034] Reference Figure 1A tethered high-altitude cleaning drone includes a drone body 1, a power distribution cabinet 2 placed on the ground for supplying power to the drone body 1, a water spraying device 3 installed on the drone body 1, and a booster device 4 placed on the ground for supplying water to the water spraying device 3. The drone body 1 is connected to the power distribution cabinet 2 via a wire 5, and the water spraying device 3 is connected to the booster device 4 via a water pipe 6. The booster device 4 is provided with a water pipe pay-off assembly 7, and a wire pay-off assembly 8 is provided on one side of the water pipe pay-off assembly 7. The wire pay-off assembly 8 is electrically connected to the power distribution cabinet 2, and a combination connector 9 is provided between the water pipe pay-off assembly 7 and the wire pay-off assembly 8 to combine the wire 5 and the water pipe 6.

[0035] During operation, the drone first flies to a designated location. When it reaches the designated location, the booster device 4 starts working and delivers water to the water spraying device 3 through the water pipe 6. The water is sprayed by the water spraying device 3 to clean the high-altitude glass. The booster device 4 is connected to the water source and continuously delivers water to the water spraying device 3. As a result, the drone body 1 does not need to carry water to fly high in the sky, thereby reducing power loss and allowing for a longer working time.

[0036] The drone body 1 is connected to the power distribution cabinet 2 via a wire 5. The power distribution cabinet 2 can store more electricity, so that the power distribution cabinet 2 can transmit more electricity to the drone body 1, thereby allowing the drone to have a longer operating time;

[0037] During the operation of the drone, the combined connector 9 connects the water pipe 6 and the wire 5 together, thereby effectively preventing the wire 5 and the water pipe 6 from being entangled with each other, thereby making the drone work more stable.

[0038] Reference Figure 1 、 Figure 2 The combined connector 9 includes a combined support frame 91, a zipper 92 is installed on the combined support frame 91, a zipper 90 is installed on the wire 5 and the water pipe 6, and the zipper 92 controls the connection and separation of the zipper 90;

[0039] During the drone's ascent, the drone body 1 pulls the wire 5 and the water pipe 6 upward, and the pulling force causes the zipper 90 installed on the wire 5 and the water pipe 6 to move upward. Under the action of the zipper 92, the zipper 90 is connected together, thereby connecting the wire 5 and the water pipe 6 together, thereby preventing the wire 5 and the water pipe 6 from being entangled with each other. When the drone body 1 is descending, the water pipe pay-off assembly 7 and the electric wire pay-off assembly 8 respectively pull the wire 5 and the water pipe 6 downward. Under the action of the zipper 92, the water pipe 6 and the wire 5 are separated from each other, and the water pipe 6 and the wire 5 are respectively wound around the water pipe pay-off assembly 7 and the electric wire pay-off assembly 8.

[0040] A limit plate 93 is mounted at the lower end of the zipper 92, and a limit roller 94 is mounted on the limit plate 93. The limit roller 94 is used to bring the wire 5 and the water pipe 6 closer to each other; under the action of the limit roller 94, the wire 5 and the water pipe 6 will not deviate during their movement.

[0041] An H-shaped support rod 95 is fixedly installed at the lower end of the zipper 90. The H-shaped support rod 95 is used to limit the zipper 90 so that the zipper 90 can be quickly aligned. Under the action of the H-shaped support rod 95, the zipper 90 is limited in the grooves on both sides of the H-shaped support rod 95. The two zippers 90 can be quickly aligned so that the zippers 90 can be quickly combined or separated.

[0042] Reference Figure 3 、 Figure 4 , a pair of water pipe support platforms 71 are installed on the water pipe pay-off assembly 7, and a water pipe pay-off drum 72 is rotatably installed on the water pipe support platform 71. A rotating sleeve 73 is provided in the center of the water pipe pay-off drum 72, and a fixed sleeve 74 is provided on the water pipe support platform 71. The rotating sleeve 73 is sleeved on the fixed sleeve 74. The fixed sleeve 74 is provided with a plurality of water-permeable holes 75. A pair of air bags 76 are fixedly installed on the rotating sleeve 73. One end of the rotating sleeve 73 is connected to the boosting device 4; the end of the water pipe 6 is fixed on the rotating sleeve 73, and the gap between the rotating sleeve 73 and the fixed sleeve 74 is connected to the water pipe 6; a water pipe pay-off motor 77 that drives the water pipe pay-off drum 72 to rotate is fixed on the water pipe support platform 71;

[0043] During the ascent of the drone body 1, the water pipe 6 wound on the water pipe pay-off drum 72 is paid out, and the rotating sleeve 73 rotates on the fixed sleeve 74 at this time. When the drone body 1 reaches the specified height, the boosting device 4 is turned on, and water enters the fixed sleeve 74 from the boosting device 4, and then is discharged from the water permeable hole 75. At this time, the water enters the gap between the rotating sleeve 73 and the fixed sleeve 74, and squeezes the airbag 76 under the action of water pressure. The diameter of the airbag 76 becomes larger, so the water is transported from the water pipe 6 to the water spraying device 3, and water is sprayed through the water spraying device 3 to clean the high-altitude buildings; when the boosting device 4 stops supplying water, the water pressure in the gap between the rotating sleeve 73 and the fixed sleeve 74 decreases. At this time, the volume of the airbag 76 becomes smaller, and the rotating sleeve 73 can rotate relative to the fixed sleeve 74. At this time, the water pipe 6 can be wound around the water pipe pay-off drum 72.

[0044] Reference Figure 5 、 Figure 6 、 Figure 7The wire pay-off assembly 8 includes a wire pay-off frame 81, a wire pay-off drum 82 rotatably mounted on the wire pay-off frame 81, a rotating sleeve 83 fixedly mounted at the center of the wire pay-off drum 82, a cable sleeve 84 fixedly mounted on the wire pay-off frame 81, and the rotating sleeve 83 sleeved on the cable sleeve 84. A plurality of internal wiring terminals 85 are fixedly mounted in the cable sleeve 84, and three conductive rings 86 are mounted on the outside of the cable sleeve 84. The three conductive rings 86 are respectively connected to the neutral line, the live line and the ground line, and the conductive rings 86 are electrically connected to the internal wiring terminals 85. The neutral wire, live wire and ground wire of the electrical cabinet 2 are connected to the internal terminal 85; three brush rings 87 are fixedly installed on the inner side of the rotating sleeve 83, and the external terminal 88 is fixedly installed on the outer side of the rotating sleeve 83. The brush ring 87 is electrically connected to the external terminal 88, and the three external terminals 88 are connected to the internal terminal 85 of the wire 5; a wire pay-off motor 89 is installed on the wire pay-off rack 81 to drive the wire pay-off drum 82 to rotate; the brush ring 87 is connected to the conductive ring 86 by sliding contact, so that a steady supply of electric energy can be transmitted to the drone body 1.

[0045] When cleaning is completed, the wire pay-off motor 89 drives the wire pay-off drum 82 to rotate, and the water pipe pay-off motor 77 drives the water pipe pay-off drum 72 to rotate, keeping the speed consistent, and the wire 5 is wound on the wire pay-off drum 82, and the water pipe 6 is wound on the water pipe pay-off drum 72;

[0046] The wire 5 and the water pipe 6 move under the action of the pulling force, and the zippers 90 installed on the wire 5 and the water pipe 6 can be separated from each other under the action of the zipper 92.

[0047] Reference Figure 8 、 Figure 9 The boosting device 4 includes a plurality of high-pressure pumps 41, the water inlet end of the high-pressure pump 41 is connected to the water source, and the water outlet end of the high-pressure pump 41 is installed with a connecting pipe 42, a first one-way valve 43 is provided between the high-pressure pump 41 and the connecting pipe 42, the connecting pipe 42 is connected to the fixed sleeve 74, and a second one-way valve 44 is provided between the connecting pipe 42 and the fixed sleeve 74; the plurality of boosting high-pressure pumps 41 are all connected to the water source, and water is input into the connecting pipe 42, multiple water flows are brought together, and the water flows are superimposed to increase the water flow rate and increase the pressure in the connecting pipe 42 and the water pipe 6. The first one-way valve 43 and the second one-way valve 44 can reduce the reverse flow of water and affect the water delivery;

[0048] The high-pressure pump 41 includes a boosting chamber 411, a boosting plug 412 slidably installed in the boosting chamber 411, and a telescopic driving member 413 installed at the end of the boosting chamber 411. A water inlet pipe 414 is provided on the side of the boosting chamber 411; when water enters the boosting chamber 411 from the water inlet pipe 414, the telescopic driving member 413 (which can be a hydraulic lever, a pneumatic lever or an electric telescopic rod) drives the boosting plug 412 to move, applies pressure to the water in the boosting chamber 411, pressurizes the water into the connecting pipe 42, and finally transports it to the water supply pipe 6.

[0049] Reference Figure 10 The water spraying device 3 includes a water storage tank 31, a booster pump 32 installed on the water storage tank 31, a water spraying pipe 33 installed at the end of the booster pump 32, and a water spraying nozzle 34 installed on the water spraying pipe 33; the water storage tank 31 is connected to the water delivery pipe 6;

[0050] When the water pipe 6 is transported to the water spraying device 3 through the boosting device 4, the water is first stored in the water storage tank 31, then pressurized by the boosting pump 32 and transported to the water spraying pipe 33 and then sprayed out from the water spraying nozzle 34, thereby solving the problem of insufficient water pressure after transporting water to a high place.

[0051] Reference Figure 10 、 Figure 11 A balancing assembly 35 is installed on the lower side of the drone body 1. The balancing assembly 35 is used to maintain the balance of the drone body 1 during the water spraying process. The balancing assembly 35 includes a balancing support platform 351 installed on the lower side of the drone body 1, a balancing support frame 352 is installed on the upper side of the balancing support platform 351, a sliding track 353 is installed on the balancing support frame 352, a balancing slider 354 is installed on the sliding track 353, a balancing motor 355 is installed on the balancing support frame 352, a balancing rack 356 is installed on the balancing slider 354, and the balancing motor 355 is installed on the balancing support frame 352. The output end is equipped with a balancing gear 357 that cooperates with the balancing rack 356. A balancing sensor 358 is installed on the drone body 1. When the drone body 1 is operating at high altitude, a reverse impact force is generated during the water spraying process and the liquid level stored in the water tank 31 changes. At this time, the balance of the drone body 1 changes. After sensing the change in the balance of the drone body 1, the balancing sensor 358 controls the forward and reverse rotation of the balancing motor 355 and controls the movement of the balancing slider 354. By changing the center of gravity position of the drone body 1, the drone body 1 can quickly restore balance.

The suspension rope 3582 connects the suspension member 3581 to the drone body 1. The front and rear ends of the suspension rope 3582 are designed with inductive travel switches 3583. When the suspension member 3581 moves toward the front of the drone body 1, the inductive travel switch 3583 at the front end senses the approach of the suspension rope 3582, causing the balance motor 355 to rotate forward, causing the balance slider 354 to move forward, and thus shifting the center of gravity of the drone body 1 forward. When the suspension member 3581 swings backward, the inductive travel switch 3583 at the rear end senses the approach of the suspension rope 3582, causing the balance motor 355 to rotate backward, causing the balance slider 354 to move backward, and thus shifting the center of gravity of the drone body 1 backward. By changing the center of gravity position of the drone body 1, the drone body 1 can quickly regain balance.

[0053] Reference Figure 12 A plurality of battery packs 21 are installed inside the power distribution cabinet 2. Battery racks 22 are installed on the battery packs 21. Battery support rods 23 are installed between the battery racks 22. The battery support rods 23 are used to keep a certain distance between the battery packs 21. Heat dissipation holes 24 are opened on the power distribution cabinet 2 to allow air to flow between the battery packs 21, thereby facilitating the dissipation of heat generated by the battery packs 21 during the charging and discharging process, and effectively preventing the power distribution cabinet 2 from overheating.

[0054] A transformer assembly 25 is installed on the power distribution cabinet 2, which transforms the voltage of the battery pack 21 to provide a temperature-controlled voltage for the drone body 1. A display screen 26 is installed on the power distribution cabinet 2, which is used to display the remaining battery power, operating voltage and operating current.

[0055] Reference Figure 9 The drone body 1 is equipped with a backup battery 11 and a camera 12.
