Description

Technical Field

[0001] The utility model relates to the field of insulator cleaning, in particular to an insulator cleaning drone. Background Art

[0002] Insulator cleaning refers to cleaning the surface of the insulator to remove impurities such as stains, dust, oil, etc. These impurities may affect the insulation performance of the insulator and cause safety problems such as leakage or short circuit.

[0003] At present, the insulator cleaning device of the multi-rotor UAV cleans the insulator by using the telescopic arm of the UAV to set up a nozzle. However, since the telescopic arm structure cannot be flipped, it can only clean the insulators arranged vertically, and it is inconvenient to clean the insulators arranged horizontally or inclined, so the scope of application is small.

[0004] Therefore, an insulator cleaning drone is provided to solve the above problems. Utility Model Content

[0009] In order to be able to clean insulators set at different inclination angles, the cleaning mechanism includes a swing arm hinged on the connecting seat, a flip motor fixedly mounted on the connecting seat and with an output shaft connected to the swing arm hinge shaft, an electric telescopic rod with a fixed end embedded in the swing arm away from the connecting seat, a clamping claw base fixedly connected to the movable end of the electric telescopic rod, gears symmetrically arranged on the inner side of the clamping claw base and meshing with each other, a clamping claw motor fixedly mounted on the clamping claw base and with an output shaft connected to one of the gears, an arc tube fixedly connected to the gear, and a water pump fixedly mounted on the swing arm, wherein the gears are all rotatably connected to the clamping claw base; by hingedly connecting the swing arm of the cleaning mechanism to the connecting seat, the cleaning mechanism as a whole can be flipped, thereby adjusting the direction of the clamping claw, thereby facilitating adaptation to insulators of different inclinations without the need to replace different cleaning heads.

[0010] In order to facilitate the surrounding spraying of the insulator, the inlet end of the water pump is connected to the water tank through a water pipe, and the outlet end of the water pump is connected to the arc tube through a water pipe, and the inner side of the arc tube is provided with a plurality of nozzles distributed in a ring array and connected to the inside of the arc tube; by arranging a nozzle connected to the water tank on the inner side of the arc clamp, the water in the water tank is guided to spray out through the nozzle by the water pump, thereby forming a surrounding spraying of the insulator.

[0011] Preferably, in order to facilitate quick and accurate positioning, thereby facilitating water tank installation and replacement and maintenance, the water tank is provided with a positioning block, and a positioning groove is provided on the connecting seat at a position corresponding to the positioning block; by inserting the positioning block on the water tank into the positioning groove on the connecting seat, the positioning can be quickly and accurately positioned, facilitating subsequent installation.

[0012] Preferably, in order to lock the water tank, a locking bolt passing through the positioning block is screwed onto the connecting seat; the locking bolt passes through the positioning block and is screwed onto the connecting seat, thereby locking the water tank onto the connecting seat.

[0013] Preferably, in order to facilitate the insertion of the lock bolt after positioning the water tank, a positioning hole is provided on the positioning block to accommodate the lock bolt to pass through; the lock bolt passes through the positioning hole to facilitate locking the positioning block on the connecting seat.

[0014] Preferably, in order to rationally utilize space and balance the load-bearing capacity of the UAV, the water tank is in a concave shape, and the active position of the swing arm corresponds to the depression of the water tank; by designing the active position of the swing arm in the depression of the concave-shaped water tank, the weight of the water tank is balanced by the weight of the swing arm and other parts thereon, which is beneficial to the stability of the UAV body during flight and hovering, thereby reducing the difficulty of cleaning.

[0015] Preferably, in order to realize the detachable water pipe and facilitate the replacement of the water tank, the water tank has a symmetrically arranged water pipe joint on one side close to the swing arm; the water pipe can be conveniently disassembled and assembled through the water pipe joint on the water tank, thereby facilitating the replacement of the water tank.

[0016] (III) Beneficial effects

[0017] The insulator cleaning drone can automatically clean insulators through an integrated cleaning mechanism. The coordinated use of the flip motor, electric telescopic rod and gripper motor can adjust the position and opening degree of the arc tube to adapt to insulators of different inclinations. The cleaning liquid is evenly sprayed onto the surface of the insulator through a water pump to achieve efficient and thorough cleaning.

[0018] The water tank of the insulator cleaning drone is easy to disassemble and install through the design of positioning blocks and locking bolts, making the maintenance or replacement of the water tank simple and convenient. At the same time, the water pipe joint design on the water tank also facilitates the disassembly and assembly of the water pipe, further improving the convenience of maintenance.

[0033] When in use, the UAV body 1 with the water tank 3 and the cleaning mechanism 5 is suspended near the insulator. According to the inclination of the insulator, the swing arm 51 is driven by the flip motor 511 to flip and adjust until its inclination is consistent with the insulator. At this time, the electric telescopic rod 52 is extended to make the arc tube 56 in the open state located on both sides of the insulator, and then the gear 54 is driven to rotate by the clamping motor 55, thereby synchronously driving another gear 54 to rotate, so that the two arc tubes 56 connected to different gears 54 are close to each other until they are surrounded by the insulator, and the cleaning liquid in the water tank 3 is supplied to the arc tube 56 through the water pipe by the water pump 4, and then sprayed onto the surface of the insulator through the nozzle 561 for flushing, thereby completing the cleaning of the insulator.

[0034] Furthermore, the water tank 3 is in a concave shape, and the active position of the swing arm 51 corresponds to the depression of the water tank 3; by designing the active position of the swing arm 51 in the depression of the concave water tank 3, the weight of the water tank 3 is balanced by the weight of the swing arm 51 and other parts thereon, which is beneficial to the stability of the drone body 1 during flight and hovering, thereby reducing the difficulty of cleaning.

[0035] It should be noted that the water tank 3 has a symmetrically arranged water pipe joint 33 on one side close to the swing arm 51 ; the water pipe joint 33 on the water tank 3 can be used to conveniently disassemble and assemble the water pipe, thereby facilitating the replacement of the water tank 3 .

[0036] Example 2
