DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] In order to more clearly understand the technical solution provided by the embodiments of the present application, the operating principle and conditions of an existing mobile device for entering and exiting a strong electric field along an insulator string are first briefly introduced.

[0033] In recent years, with the rapid development of cross-regional power grids, UHV transmission lines have taken on the important task of transmitting electric energy across regions, delivering hundreds of millions of kilowatt-hours of clean electricity to various regions every year, serving the entire social and economic development. Therefore, it is particularly important to ensure the long-term safe and stable operation of UHV transmission lines.

[0034] Compared with power outages for maintenance of transmission lines, live working is becoming an important way to ensure the smooth operation of transmission lines with its great economic advantages and extremely low time cost.

[0035] In the existing technology, workers need to use both hands and feet, and there is a sound of discharge when moving in a strong electric field, which causes psychological tension, resulting in low efficiency of workers crossing insulators and increased work intensity. When workers walk on the insulator string, the outer cylindrical surface of the insulator string is smooth, which is extremely inconvenient for workers to walk on it and affects maintenance efficiency.

[0036] The present invention provides Figures 1 to 6 A mobile device and a method of use for entering and exiting a strong electric field along an insulator string are shown, comprising an inspection chamber 1, a supporting mechanism is arranged inside the inspection chamber 1, telescopic mechanisms are fixed on both sides of the inspection chamber 1, a flipping mechanism 4 is arranged on one side of the telescopic mechanism, and two clamping mechanisms 406 are arranged at both ends of one side of the flipping mechanism 4.

[0037] When in use, the width of the maintenance compartment 1 is adjusted by the telescopic mechanism so that the maintenance compartment 1 can be horizontally placed in between, and then the flipping mechanism 4 is used to flip it between the insulator strings to ensure that the maintenance compartment 1 can move forward in between. When reaching the designated maintenance position, the protruding part of the insulator string is clamped by the clamping mechanism 406 to ensure that the maintenance device can be stably fixed between the two insulator strings.

[0038] The supporting mechanism comprises two movable rods 101 , and the top ends of the two movable rods 101 are provided with supporting plates 102 , and the supporting plates 102 are connected to the inner side walls of the maintenance chamber 1 .

[0039] Bumps are provided on both sides of the support plate 102 , and slide grooves 103 are provided on the inner side walls of the maintenance bin 1 . The inside of the slide grooves 103 is connected to the bumps of the support plate 102 .

[0040] During use, when the maintenance bin 1 reaches the specified position, the support plate 102 is lifted up by the movable rod 101. During the lifting process, the support plate 102 slides along the slide groove 103. At the same time, the position of the support plate 102 is limited. There are two movable rods 101, and the two movable rods 101 are lifted synchronously to avoid the position shift of the support plate 102 during the lifting process, which makes it impossible for workers to stand on the top of the support plate 102, affecting the progress of maintenance.

[0041] The telescopic mechanism includes fixed blocks 104 fixed on both sides of the maintenance compartment 1 , one end of the fixed block 104 is provided with a telescopic rod 2 , and the movable end of the telescopic rod 2 is connected to a connecting block 3 .

[0042] The connecting block 3 is L-shaped, the transverse block of the connecting block 3 is connected to the movable end of the telescopic rod 2, and the vertical block of the connecting block 3 is provided with a turning mechanism 4.

[0043] The flipping mechanism 4 includes a support frame 402, which is fixed on the end face of the vertical block of the connecting block 3. A motor 401 is provided at the other end of the support frame 402, and a driving wheel 403 is provided at the output end of the motor 401. The driving wheel 403 is located inside the support frame 402 and is provided on one side of the vertical block of the connecting block 3.

[0044] A driven wheel 404 is provided above the driving wheel 403 . The driven wheel 404 passes through the vertical block of the connecting block 3 and is connected to a rotating wheel 405 . Two clamping mechanisms 406 are provided on the other circular surface of the rotating wheel 405 .

[0045] When in use, the telescopic rod 2 on one side of the fixed block 104 drives the connecting block 3 to extend and retract, ensuring that the maintenance bin 1 can be horizontally mounted in between for maintenance. The movable end of the telescopic rod 2 drives the connecting block 3 to move. The connecting block 3 is L-shaped, and the angle between the horizontal block and the vertical block is 90 degrees, in order to better install and fix the flip mechanism 4.

[0046] The vertical block is used to install the flipping mechanism 4 and prevent the horizontal block from interfering with the movement of the flipping mechanism 4. It is fixed on the end face of the vertical block through the support frame 402 and the motor 401. The rotating end of the motor 401 drives the driving wheel 403 to rotate, and the driving wheel 403 drives the driven wheel 404 to rotate. The driven wheel 404 penetrates the vertical block and drives the rotating wheel 405 to rotate. During the rotation process, the rotating wheel 405 drives the clamping mechanism 406 to flip. The two clamping mechanisms 406 are horizontally arranged in the gap between the insulator strings. At the same time, the movable clamping mechanism 406 clamps the protruding part of the insulator string to fix the detection device between the two insulator strings.

[0047] The clamping mechanism 406 includes a mounting plate 4061, one side of which is arranged on the end face of the rotating wheel 405, a telescopic block 4062 is arranged at the top of the mounting plate 4061, the movable end of the telescopic block 4062 is connected to a connecting strip 4063, a first fixing strip 4064 is arranged on the side of the connecting strip 4063 away from the telescopic block 4062, and movable strips 4066 are hingedly arranged on both sides of the first fixing strip 4064.

[0048] A mounting block 4065 is mounted on the other side of the top of the mounting plate 4061 , and the mounting block 4065 is coaxial with the telescopic block 4062 .

[0049] A second fixing bar 4068 is provided at the top of the mounting block 4065 , and clamping blocks 4067 are hinged on both sides of the second fixing bar 4068 , and the clamping blocks 4067 are hinged to the movable bar 4066 .

[0050] During use, when the clamping mechanism 406 moves to the clamping position, the connecting strip 4063 is driven to move by the telescopic block 4062. The connecting strip 4063 is used to compensate for the length to avoid the movable strip 4066 being insufficient in length and unable to connect with the clamping block 4067. The first fixed strip 4064 and the movable strip 4066 can be easily replaced. When damage occurs, only the first fixed strip 4064 needs to be removed, and the telescopic block 4062 cannot be removed, thereby avoiding subsequent position calibration of the telescopic block 4062.

[0051] The telescopic block 4062 drives the connecting bar 4063 to move, the connecting bar 4063 drives the first fixed bar 4064 to move, the first fixed bar 4064 drives the movable bars 4066 on both sides to move, the movable bars 4066 drive the clamping block 4067 to move, the movable bars 4066 control the expansion and retraction of the clamping block 4067, the clamping block 4067 is hinged on both sides of the second fixed bar 4068, the second fixed bar 4068 is fixed, and only the clamping block 4067 is driven to move by the movable bar 4066 to clamp the insulator string.

[0052] Working principle: before entering the electric field, the width of the maintenance chamber 1 on both sides is adjusted by the telescopic rod 2 to ensure that the maintenance chamber 1 can be horizontally mounted between the two lines. The telescopic rod 2 is extended and retracted to drive the connecting block 3 to move. The flip mechanism 4 of the connecting block 3 is extended to the gap between the insulator strings. Then, the connecting bar 4063 is driven to move by the telescopic block 4062. The connecting bar 4063 drives the first fixed bar 4064 to move away from the connecting bar 4063. The first fixed bar 4064 drives the movable bars 4066 on both sides to move. The movable bar 4066 drives the clamping block 4067 to move. The movable bar 4066 controls the clamping block 4067 to retract. The clamping block 4067 is hinged on both sides of the second fixed bar 4068. The second fixed bar 4068 is fixed and only The clamping block 4067 is driven to move by the movable bar 4066, and the movable bar 4066 drives the clamping block 4067 to move in the direction of the insulator string to clamp the insulator string. When it is necessary to move forward, the telescopic block 4062 drives the connecting bar 4063 to move, and the connecting bar 4063 moves in the direction of the telescopic block 4062. The connecting bar 4063 drives the first fixed bar 4064 to move, and the synchronous movable bar 4066 follows the movement of the first fixed bar 4064. The movable bar 4066 drives the clamping block 4067 to expand, so that the clamping block 4067 no longer clamps the insulator string, and the clamping block 4067 is kept in an expanded state. At this time, the clamping block 4067 is in a loosened state, and then the motor 401 rotates, and the motor 401 drives the driving wheel 403 to rotate, and the driving wheel 403 drives The driven wheel 404 rotates, and the driven wheel 404 drives the rotating wheel 405 to rotate. The clamping mechanism 406 on the rotating wheel 405 rotates with the rotating wheel 405. During the rotation process, the clamping mechanism 406 is in a state where one clamping mechanism 406 contacts the gap between the insulator strings and is under pressure, and the other clamping mechanism 406 is in a suspended state. The rotating wheel 405 continues to rotate, and the clamping mechanism 406 in the suspended state contacts the gap between the insulator strings and is under pressure. The clamping mechanism 406 that was previously under pressure is suspended in this way, and the forward state is achieved by alternating. In the process of the flipping mechanism 4 flipping, the clamping mechanism 406 is in an open state, but the opened clamping block 4067 cannot contact the edge of the insulator string, and will not be damaged by the clamping block 4067. During the flipping, the clamping block 4067 damages the insulator string, and during the flipping process, the movable rod 101 drives the support plate 102 to retract, so that the support plate 102 is at the bottom of the maintenance chamber 1. Because the maintenance device is in a bumpy state during the flipping process, one is high and the other is low. At this time, the staff must be inside the maintenance chamber 1 to avoid the staff's center of gravity being unstable due to the bumpy state. After the flipping mechanism 4 reaches the specified position, the clamping mechanism 406 retracts, and the clamping mechanism 406 clamps the protruding part of the insulator string to fix the device at the maintenance location. Then, the support plate 102 is lifted by the movable rod 101. During the lifting process, the support plate 102 slides along the slide groove 103, and the position of the support plate 102 is limited at the same time. There are two movable rods 101.The two movable rods 101 are lifted synchronously to avoid the position shift of the support plate 102 during the lifting process of the support plate 102, which would make it impossible for workers to stand on the top of the support plate 102 and affect the progress of maintenance.

[0053] The method of use is as follows: first, the maintenance compartment 1 is installed on the circuit to be maintained through the telescopic mechanism, and the maintenance compartment 1 is fixed on the insulator string of the circuit by clamping it with the clamping mechanism 406.

[0054] Secondly, the clamping mechanism 406 is driven to flip through the flipping mechanism 4, and the clamping mechanism 406 is released while flipping.

[0055] Finally, it is flipped to the designated position, the clamping mechanism 406 clamps the insulator string, and the telescopic mechanism is extended and retracted to transport the staff to the circuit maintenance position.

[0056] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
