[0031] The embodiment of the application discloses a high-voltage distribution network live working device.

[0035] According to the above arrangement, in use, the user can be at a relatively far position to make the working head approach the insulator of the power transmission and distribution network facility through the insulating rod 1, and complete the insulator detection work by returning the video collected by the camera unit 5 on the working head to the terminal palm computer 2; because the camera unit 5 can move, the insulator can be detected at multiple angles by appropriately adjusting the position of the insulating rod 1; and because the user is relatively far away from the insulator, i.e., the live position, and there is the insulating rod 1 in between, the probability of accidental electric shock can be greatly reduced, and the safety of live working of the distribution network line can be improved.

[0036] In an embodiment of the present application, the adaptive balance mechanism 4 further comprises a ball seat 42, a main shaft 43, a secondary shaft 44, and a balance ball 45, wherein the ball seat 42 is in a more than half hemispherical structure in this embodiment, which covers the spherical body of the joint 3 to be ball-jointed.

[0037] The main shaft 43 extends horizontally and is fixed to the top of the ball seat 42; one end of the main shaft 43 is connected to the C-shaped guide seat 41, and the other end is mounted with the balance ball 45. One end of the secondary shaft 44 is fixed to the ball seat 42, or in other words, is fixed horizontally and vertically to the main shaft 43; the secondary shaft 44 is two and symmetrically distributed on both sides of the main shaft 43, and the end of the secondary shaft 44 away from the main shaft 43 is mounted with another balance ball 45.

[0038] According to the above setting, only the position of the balance ball 45 is adjusted, the main shaft 43 can still maintain horizontal in the case of the insulator rod 1 being tilted, so that the user can shoot the image of the insulator through the camera unit 5 on the C-shaped guide seat 41 on the main shaft 43, and better operation.

[0039] In an embodiment of the present application, the C-shaped guide seat 41 is transversely arranged, an arc slot is formed along the length, a sliding block one 411 and a sliding block two 412 are slidably connected in the arc slot, and a reset spring 413 is arranged; the reset spring 413 is an arc-shaped spring adapted to the arc slot, and the two ends thereof are fixed to the sliding block one 411 and the sliding block two 412 respectively; the sliding block two 412 is close to the middle part of the C-shaped guide seat 41, and the camera unit 5 is embeddedly installed on the sliding block one 411 with the lens facing outward.

[0040] An arc-shaped through slot is formed at one end of the main shaft 43, and the C-shaped guide seat 41 passes through the through slot and is slidably connected. The driving unit 6 includes two traction units 61 respectively used for pulling the sliding block one 411 and the end of the C-shaped guide seat 41 away from the sliding block one 411, and further includes a blocker used for blocking the movement of the sliding block two 412, the traction units 61 are installed on the main shaft 43, and the blocker is installed on the sliding block two 412, the blocker and the traction units 61 are wirelessly connected to the terminal palm computer 2.

[0041] In use:

[0042] In the first stage, the sliding block two 412 is close to the middle part of the main shaft 43 and the C-shaped guide seat 41; the blocker is first turned on to stop the sliding block two 412, and the traction unit 61 pulling the C-shaped guide seat 41 is turned off; then the other traction unit 61 is turned on to pull the sliding block one 411 to slide and move towards the sliding block two 412, at this time, the camera unit 5 moves towards the middle part of the C-shaped guide seat 41 while collecting images;

[0043] In the second stage, the traction unit 61 pulling the sliding block one 411 is released, and the sliding block one 411 is reset under the action of the reset spring 413; at the same time, the other traction unit 61 is started to pull the end of the C-shaped guide seat 41 away from the sliding block one 411 to move towards the main shaft 43, at this time, the other end of the C-shaped guide seat 41 drives the sliding block one 411 to move circumferentially, and the camera unit 5 can shoot the image of another area;

[0044] In the third stage, the traction unit 61 pulling the C-shaped guide seat 41 is released, and the traction unit 61 pulling the sliding block one 411 drives the sliding block one 411 to move towards the main shaft 43, and the C-shaped guide seat 41 is reset by the reaction force of the reset spring 413.

[0045] According to the above setting, two C-shaped guide seats 41 of the present application with opposite structures are prepared, so that each insulator can be observed circumferentially.

[0046] The blocking device is mainly arranged to facilitate the user to adjust the overall position of the slider 1 and the slider 2 according to the demand and the elastic force of the reset spring 413; the blocking device can be a micro electric cylinder which is embedded in the insulating (plastic, resin) slider 2 and has a rubber block fixed at the end thereof extending towards the inner wall of the arc groove.

[0047] With reference to Figure 2 and Figure 3 The traction unit 61 comprises a rope shaft 611, a motor 1 612 and a traction rope, wherein the rope shaft 611 is rotatably connected to the side wall of the main shaft 43 through a support, the motor 1 612 is installed on the support and the main shaft and has an output shaft fixed to the rope shaft 611; one end of the traction rope of one traction unit 61 is fixed to the rope shaft and the other end is fixed to the C-shaped guide base 41; one end of the traction rope of the other traction unit 61 is fixed to the rope shaft and the other end is fixed to the slider 1 411. The motor 1 612 can be a servo motor which is electrically connected to the control board.

[0048] It can be understood that the C-shaped guide base 41, i.e. the side wall of the arc groove, has an opening for the traction rope to pass through so as to avoid the slider 1 411 from being unable to be pulled; meanwhile, the reset spring 413 is sleeved with a bellows 414 on the outer wall thereof to prevent the traction rope from being accidentally clamped into the reset spring 413 and affecting the use effect.

[0049] According to the above arrangement, the motor 1 612 can be operated to realize the winding and unwinding of the traction rope; the traction rope is adopted because of the high-voltage environment near the insulator, in order to prevent the air from being broken down and the motor 1 612 from being damaged by creeping, so the traction rope is used to keep away from the middle part.

[0050] In one embodiment of the present application, the main shaft 43 comprises a fixed shaft 431 and a movable shaft 432 which have the same center axis, wherein the fixed shaft 431 is connected to the secondary shaft 44 and the balance ball 45; one end of the movable shaft 432 is fixed to a rotating shaft which is inserted into the fixed shaft 431 and rotatably connected to the fixed shaft 431; the motor 2 is embedded in the fixed shaft 431, the output shaft of the motor 2 is fixed to the rotating shaft, and the motor 2 is electrically connected to the control board.

[0051] According to the above arrangement, the motor 2 is rotated to drive the movable shaft 432 to adjust the direction, such as 180° reverse rotation, so as to exchange the positions of the two ends of the C-shaped guide base 41; the arrangement makes it possible to observe the circumference of the insulator by using only one device of the present application, so the use effect is better.

[0052] In one embodiment of the present application, a cavity is arranged in the ball of the joint 3 and a through hole is formed in the cavity, a positioning block is slidably arranged in the through hole, and the positioning block and the through hole are elastically and sealingly connected, such as being connected by a rubber sheet which is bonded after being melted;

[0053] The insulating rod 1 is provided with a conducting cavity along the length direction and is opened at one end close to the joint 3; the cavity of the joint 3 extends downward and is provided with a port corresponding to the opening of the conducting cavity, that is, when the joint 3 is installed on the insulating rod 1, the conducting cavity and the cavity are communicated.

[0054] The insulating rod 1 can be made of insulating materials such as plastic, resin, glass, etc., the lower end of the conducting cavity of which is slidably connected with a piston column 11, the middle part of which is flattened and fixed with a vertical handle 12; the lower end of the piston column 11 is fixed with a locking spring; the insulating rod 1 is provided with a window for the movement of the handle 12.

[0055] According to the above arrangement, the positioning block on the joint 3 is protruded under the action of the locking spring pushing the piston column 11, the protruded ball can realize the positioning and locking of the ball seat 42, that is, the position of the self-adaptive balancing mechanism 4 is relatively fixed, which helps the user to lock the position after adjusting the position, preventing the tilt caused by the change of the gravity center of the structure adjustment on the C-shaped guide seat 41; when the self-adaptive balancing mechanism 4 needs to be freely movable, the handle 12 can be pulled down.

[0056] In an embodiment of the present application, the present application further comprises an insulating waistband, which comprises a waistband body and a plurality of insulating sleeves fixed on the waistband body, the insulating sleeves are vertical and the upper part is open for the insertion of the insulating rod.

[0057] The arrangement of the insulating waistband can enable the user to insert the insulating rod 1 into the insulating sleeve for force amplification, preventing the user from holding the lower end of the insulating rod 1 and the weight of the insulating rod 1 being concentrated on the upper part, which is too laborious due to the force arm amplification effect.

[0058] In an embodiment of the present application, the above-mentioned balancing ball 45 is slidably connected with the main shaft 43 and the auxiliary shaft 44, and the sliding direction is axial; the balancing ball 45 is threadedly connected with a bolt 46, and the bolt 46 penetrates the balancing ball 45 and abuts against the corresponding main shaft 43 or auxiliary shaft 44.

[0059] The main shaft 43 and the auxiliary shaft 44 are respectively provided with scales along the length direction.

[0060] According to the above arrangement, the user can adjust the position of the balancing ball 45 before each use, so that the posture of the self-adaptive balancing mechanism 4 is adjusted to a suitable condition, and because there is a scale as a reference, the adjustment is relatively convenient.

[0061] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
