Description

Technical Field

[0001] This utility model relates to the technical field of drone cleaning equipment, specifically to a live-line cleaning device for drones. Background Technology

[0002] A drone is an aircraft that does not require a pilot to operate it from inside the aircraft. It flies autonomously through remote control devices (such as remote controllers or ground stations) or preset programs. It integrates technologies such as aerodynamics, electronic communication, sensors, and autopilot, and can perform a variety of tasks. It has been widely used in many fields.

[0003] Among related technologies, a search revealed a Chinese patent with patent number CN202022632428.1 that discloses "a remote-controlled drone with an electric cleaning device". This device uses a water tank to load cleaning water mixed with cleaning reagents, and uses the drone as a carrier to move to a high place where cleaning is needed. It uses a pump and a spray nozzle to rinse the area to be cleaned. The device is simple to operate, convenient to use, and simplifies the difficulty of high-rise cleaning operations.

[0004] The water tank of this device is fixed to the bottom plate of the drone's fuselage via the top. The water tank is mostly cubic or cylindrical. When the drone is being cleaned, it is at a high altitude and is subjected to crosswinds. The crosswinds directly impact the side walls of the water tank, thus affecting the stability of the drone during flight. In addition, the vibration of the liquid sprayed from the water pipe will generate recoil force fluctuations, causing dynamic disturbances, which are transmitted to the drone fuselage through the structure, thus affecting flight stability. To solve the above problems, an electrified cleaning device for drones is proposed. Utility Model Content

[0005] In view of this, the present invention provides an electric cleaning device for unmanned aerial vehicles (UAVs). The present invention uses an adjustment component to clamp the water spray pipe with an arc-shaped sleeve, and then uses a reinforcing rod and a buffer spring on the buffer component to absorb the impact force. The impact force is transmitted to the buffer block, which can further reduce the impact fluctuation, thereby weakening the impact fluctuation generated when the water spray pipe sprays water, thus stabilizing the flight attitude. Furthermore, the guide plates on both sides of the water tank further reduce the impact of crosswinds on the flight of the UAV, thereby further stabilizing the flight stability when spraying water.

[0006] To solve the above-mentioned technical problems, this utility model provides a live cleaning device for unmanned aerial vehicles (UAVs), including a base plate at the bottom of the UAV fuselage, a water tank at the bottom of the base plate, a water spray pipe connected to the water outlet of the water tank, the upper half of the water tank being rectangular and the lower half being arc-shaped, multiple guide plates being provided on both sides of the upper half of the water tank, the guide plates being streamlined, guide flanges being provided on both sides of the top of the water tank, and a connecting component being provided at each of the four corners of the top of the water tank, which is connected to the base plate, an adjustment component being provided on the water spray pipe, a buffer component being provided on the upper part of the adjustment component, and the buffer component being connected to the base plate.

[0007] Each connecting component includes an arc-shaped connecting block connected to the guide flange. The arc-shaped connecting block is used to connect the water tank to the support rod. A support rod is provided on the top of the arc-shaped connecting block. The support rod is used to connect the arc-shaped connecting block to the drone's base plate. The support rod is circular, and its top is connected to the base plate.

[0008] The adjustment assembly includes a pair of arc-shaped clamps for securing the water spray pipe. The two arc-shaped clamps are used to clamp and fix the water spray pipe. A support plate is provided on the upper part of the arc-shaped clamps. The support plate is used to fix the arc-shaped clamps and install the adjustment plate. An adjustment plate is provided at each end of the bottom of the support plate. The adjustment plate is used to open threaded holes. A threaded hole is provided in the middle of the adjustment plate. The threaded hole is used to install the adjustment screw. The adjustment screw is used to adjust the distance of the arc-shaped clamps. One end of the adjustment screw is connected to the arc-shaped clamp.

[0009] The buffer assembly includes a buffer block fixed to the base plate. The buffer block is used to install the arc-shaped seat. The buffer block has built-in shock-absorbing rubber. A pair of arc-shaped seats are provided on the front part of the bottom wall of the buffer block. The arc-shaped seats are used to install the connecting shaft, so that the connecting shaft can be fixed and rotated. The connecting shaft is rotatably arranged between the arc-shaped seats. The connecting shaft is used to connect the sleeve to the arc-shaped seat. The sleeve is provided on the surface of the connecting shaft. The sleeve is used to connect the connecting shaft to the counterweight. The counterweight is provided at the bottom of the sleeve. The counterweight is used to stabilize the connecting rod and also to connect the connecting rod to the counterweight. A pair of connecting rods are provided at the bottom of the counterweight. The connecting rods are used to install the reinforcing rods, so that the reinforcing rods are connected to the counterweight. Each connecting rod is inclined towards the spray pipe side and has a reinforcing rod. The reinforcing rod is used to reinforce and stabilize the arc-shaped sleeve and prevent the arc-shaped sleeve from swinging too much. The reinforcing rods are all fixed to the upper wall of the support plate.

[0010] The buffer assembly also includes a vertical plate located at the rear of the bottom wall of the buffer block. The vertical plate is used to install the base of the buffer spring, so that one end of the buffer spring is connected to the vertical plate and fixed. A pair of buffer springs are located at the bottom of the vertical plate, and the other end of the buffer spring is connected to the reinforcing rod. The other end of each buffer spring is connected to the reinforcing rod on the same side. Thus, the axial stress released when the water spray pipe sprays water can be relieved by the buffer spring, thereby preventing the water spray pipe from swinging too much.

[0011] The water tank has a threaded interface at the outlet end, which allows the reducing fitting to be detachably connected to the water spray pipe. The reducing fitting is used to install water spray pipes of different diameters and is threadedly connected to the water spray pipe.

[0012] A level gauge is installed in the center of the top wall of the water tank. The level gauge is used to monitor the liquid level in the water tank in real time and will alarm when the liquid level is too low.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. The arc-shaped jacket clamps the water spray pipe by adjusting the component, and the impact force is absorbed by the reinforcing rod and buffer spring on the buffer component. The impact force is transmitted to the buffer block, which can further reduce the impact fluctuation, thereby weakening the impact fluctuation generated when the water spray pipe sprays water, thus stabilizing the flight attitude. Furthermore, the crosswinds on both sides of the water tank are used to reduce the impact of crosswinds on the drone's flight, thereby further stabilizing the flight stability when spraying water.

[0014] 2. Two arc-shaped sleeves are used to clamp and fix the water spray pipe. The support plate is used to fix the arc-shaped sleeves and install the adjustment plate. The adjustment plate is used to open threaded holes, and the threaded holes are used to press the adjustment screw, so that the adjustment screw can move on the adjustment plate, thereby adjusting the distance between the arc-shaped sleeve and the water spray pipe.

[0015] 3. The threaded interface is used to allow the reducing fitting to be detachably connected to the water spray pipe. The reducing fitting is used to install water spray pipes of different diameters, which improves the operability of the equipment. The level gauge is used to monitor the liquid level in the water tank in real time. When the liquid level is too low, it will alarm to remind the operator to add liquid. Attached Figure Description
