[0016] 3. When the present application controls the extension of the fourth telescopic cylinder, the turning frame will turn upward with its rotating connection as the center, thereby causing the movable end of the turning frame to rotate a certain angle and extend out of the storage slot; then, the second telescopic cylinder is controlled to extend, and the first slide slides out of the turning frame. During this period, since the outer side of the belt is fixed to the turning frame through a fixed block, the belt will rotate around the roller shaft, thereby driving the second slide to slide out of the first slide, so that the second telescopic cylinder can achieve a secondary extension action when extending, thereby enabling the present device to be used for detection of higher lines.

[0017] 4. The present application utilizes a locking bolt that penetrates into the card slot to abut and lock the clamp ammeter, making the installation and removal of the clamp ammeter of the present device more convenient, thereby significantly improving the inspection and maintenance of the clamp ammeter.

DETAILED DESCRIPTION

[0019] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of application of the present invention.

[0020] like Figure 1-5 As shown, the present invention proposes a branch line identification device for a substation, including a chassis 1, a clamp ammeter and a monitor 6. A driving wheel 13 is installed at the bottom of the chassis 1. The driving wheel 13 can adopt the electric driving wheel 13 in the prior art, which is more convenient for the movement of the device. Four ground support mechanisms are installed symmetrically at the four corners of the outside of the chassis 1. In addition, a display control panel 12 is also provided on the chassis 1 of the device. The monitor 6 and the clamp ammeter are both electrically connected to the display control panel 12, and can transmit the current data and the monitoring screen in real time to be displayed on the display control panel 12, thereby improving the convenience of use of the device.

[0021] like Figure 1 and Figure 2 As shown, each foot support mechanism includes a support leg 23, a first telescopic cylinder 22, and two support links 21. One end of the two support links 21, arranged parallel to each other, is rotatably connected to the outer wall of the chassis 1 via a first rotating shaft 241, and the other end of the two support links 21 is rotatably connected to the support leg 23 via a second rotating shaft 242. The tail end of the first telescopic cylinder 22 is rotatably connected to the first rotating shaft 241 of the lower support link 21, and the piston rod of the first telescopic cylinder 22 is tilted and rotatably connected to the second rotating shaft 242 of the upper support link 21. Furthermore, the support leg 23 includes a support rod 231 and a foot block 232. The support rod 231 is vertically movable, and the foot block 232 is rotatably connected to the lower end of the support rod 231. The piston rods of the support links 21 and the first telescopic cylinder 22 are both rotatably connected to the support rod 231. The first telescopic cylinder 22 can be a pneumatic cylinder.

[0022] After the identification device of the present application moves to the bottom of the area to be detected, the four first telescopic cylinders 22 are controlled to retract simultaneously. The two parallel supporting links 21 of the same foundation support mechanism remain parallel and swing downward with the two first rotating shafts 241 as the center, thereby causing the support legs 23 to move downward. After the support legs 23 contact the ground, as the first telescopic cylinders 22 continue to retract, the chassis 1 can be lifted upward, and the support of the four support legs 23 can significantly improve the stability of the device. In addition, in the present application, the support legs 23 are composed of a support rod 231 and a foot block 232. The foot block 232 is rotatably connected to the support rod 231. When the working ground is uneven, the rotation of the foot block 232 allows it to adapt to different ground conditions and improve the support stability of the device.

[0023] A storage slot is provided downwardly at the top of the chassis 1, and a lifting mechanism is provided in the storage slot. An openable and closable cover 11 is provided at the upper opening of the storage slot. When not in operation, the cover 11 can be used to seal the storage slot, thereby effectively protecting the equipment in the storage slot.

[0024] The lifting mechanism comprises a tilting frame 3, a lifting drive assembly, and a telescopic assembly. The tip of the tilting frame 3 is pivotally mounted in a receiving slot. The lifting drive assembly is connected to the tilting frame 3 and is used to drive the tilting frame 3 to rotate and lift. The telescopic assembly is mounted above the tilting frame 3 along its length, with a base 5 fixed to the end of the telescopic portion. Specifically, the lifting drive assembly includes a fourth telescopic cylinder 31, the rear end of which is pivotally mounted in a receiving slot below the tilting frame 3. The piston rod of the fourth telescopic cylinder 31 is tilted upward toward the side of the tilting frame 3 where it is pivotally connected, and its piston rod is pivotally connected to the lower center portion of the tilting frame 3.

[0025] The telescopic assembly includes a first slide 42, a second slide 43, and a second telescopic cylinder 41. The first slide 42 is mounted above the tilting frame 3 so as to slide along its length, while the second slide 43 is mounted on the first slide 42 so as to slide along its length. The base 5 is fixedly mounted at the end of the second slide 43. The second telescopic cylinder 41 is mounted on the tilting frame 3 parallel to the first slide 42, with the piston rod of the second telescopic cylinder 41 fixedly connected to the first slide 42. Two rollers 44 are mounted on the first slide 42 along its length, and a belt 45 is sleeved on the two rollers 44. One side of the belt 45 is fixedly connected to the tilting frame 3, and the other side is fixedly connected to the second slide 43. A fixed block 32 is fixedly mounted above the tilting frame 3, near the base 5. The fixed block 32 is fixedly connected to one side of the belt 45. The end of the second slide 43, away from the base 5, is fixedly connected to the other side of the belt 45. A first slide rail 33 is installed on the flip frame 3 along its length direction, and the bottom of the first slide plate 42 is slidably installed on the first slide rail 33; a second slide rail 421 is installed on the first slide plate 42 along its length direction, and the bottom of the second slide plate 43 is slidably installed on the second slide rail 421.

[0026] The first slide 42 and the second slide 43 of the present invention are slidably connected to the flip frame 3 and the first slide 42 respectively via corresponding slide rails, thereby significantly improving the stability of the two slides during movement. Among them, the second telescopic cylinder 41 and the fourth telescopic cylinder 31 can adopt the hydraulic cylinder structure of the prior art.

[0027] like Figure 3 and 4 As shown, when the present application controls the fourth telescopic cylinder 31 to extend, the flip frame 3 will flip upward with its rotating connection as the center, thereby causing the movable end of the flip frame 3 to rotate a certain angle and extend out of the storage slot; then the second telescopic cylinder 41 is controlled to extend, and the first slide 42 slides outward of the flip frame 3. During this period, since the outer side of the belt 45 is fixed to the flip frame 3 through the fixed block 32, the belt 45 will rotate around the roller 44, thereby driving the second slide 43 to slide outward of the first slide 42, so that the second telescopic cylinder 41 can achieve a secondary extension action when it extends, thereby enabling the present device to be adapted for detection of higher lines.

[0028] The clamp meter and monitor 6 are mounted on a base 5. A push assembly is also mounted on the base 5, corresponding to the clamp meter and used to open the clamp meter's jaws. Specifically, a slot 50 is defined at the end of the base 5, into which the clamp meter is positioned. A locking member is located within the slot 50, securing the clamp meter. The locking member includes a locking bolt 51, which is mounted outside the slot 50. The end of the locking bolt 51 extends inwardly into the slot 50 and abuts against the clamp meter housing.

[0029] The present application utilizes a locking bolt 51 that penetrates and extends into the slot 50 to abut and lock the clamp ammeter, making the installation and removal of the clamp ammeter of the device more convenient, thereby significantly improving the inspection and maintenance of the clamp ammeter.

[0030] The monitor 6 is mounted on the side of the base 5, facing the clamp-on ammeter. It provides real-time monitoring of the substation branch line conditions and the clamp-on ammeter's usage. The driving assembly includes a third telescopic cylinder 52 (which can be a pneumatic cylinder). The third telescopic cylinder 52 is positioned horizontally toward the clamp-on ammeter's jaws. An abutment block 521 is fixed to the end of the piston rod of the third telescopic cylinder 52, which abuts against the abutment block 521 to push the clamp-on ammeter open.

[0031] The clamp ammeter of the present application is moved to the bottom of the substation line cable, and the abutment block 521 is driven to move by controlling the third telescopic cylinder 52, and the jaws of the clamp ammeter are opened by using the abutment block 521. Then, the lifting mechanism is used to drive the clamp ammeter upward so that the cable is clamped into the jaws of the clamp ammeter. The third telescopic cylinder 52 is retracted and reset, so that the clamp ammeter can be used to effectively detect the line.

[0032] When using the present invention, the device moves to the bottom of the line cable in the substation, controls the four first telescopic cylinders 22 to retract simultaneously, and uses the four supporting legs 23 to support and lift up the chassis 1; then, by controlling the action of the third telescopic cylinder 52, the jaws of the clamp ammeter are opened; the fourth telescopic cylinder 31 and the second telescopic cylinder 41 are controlled to extend, and the rotation of the flip frame 3 and the extension of the telescopic assembly are used to drive the clamp ammeter to move upward and allow the cable to be clamped into the jaws of the clamp ammeter. The third telescopic cylinder 52 retracts and resets, and the jaws of the clamp ammeter are locked by the rebound of the clamp ammeter head, so that the clamp ammeter can be used to effectively detect the line.
