Through the positioning connection mechanism 3, it is convenient to position and install and support the plurality of elastic wire blocking mechanisms 4, and keep the plurality of elastic wire blocking mechanisms 4 arranged linearly.

[0033] Please refer to Figures 1 to 9, a plurality of elastic wire blocking mechanisms 4 are installed at the upper end of the positioning and connecting mechanism 3. The elastic wire blocking mechanism 4 includes a horn-shaped bent rod 403. An outer side of the bottom end of the horn-shaped bent rod 403 is provided with a horn-shaped mounting rod 402. One side of the horn-shaped mounting rod 402 is provided with a locking knob 405. One end of the locking knob 405 penetrates through the horn-shaped mounting rod 402 and is in close contact with one side of the horn-shaped bent rod 403.

The falling wires can be lifted and limited by the horn-shaped bent rod 403, the limiting inclined rod 406 and the anti-disengagement rod 407, so as to avoid the wires deviating and detaching from the horn-shaped bent rod 403;

[0034] An outer side of the bottom end of the horn-shaped mounting rod 402 is provided with a connecting ring 411. A support spring 408 is arranged on the lower end surface of the connecting ring 411. A pressure sensor 410 is arranged inside the bottom end of the support spring 408.

The pressure sensor 410 is fixedly connected with the guide seat 409. The pressure received by the horn-shaped bent rod 403 can be monitored through the pressure sensor 410, and thus the falling situation of the wires can be detected;

[0035] The connecting ring 411 is connected with the guide seat 409 through the support spring 408. An insulating tank 401 is installed on the outer side of the guide seat 409. The bottom end of the insulating tank 401 is threadedly connected with the positioning and mounting strip 305. A limiting cover 404 is installed at the upper end of the insulating tank 401. The upper end of the insulating tank 401 and the limiting cover 404 are fixedly connected by screws. The limiting cover 404 is connected with the horn-shaped mounting rod 402 through the connecting ring 411. The connecting ring 411 is threadedly connected with the horn-shaped mounting rod 402.

[0036] Please refer to Figure 5 and Figure 7, a transverse tension monitoring mechanism 2 is installed between two multi-segment insulating support mechanisms 1. The transverse tension monitoring mechanism 2 includes a transverse pull plate 201. Both ends of the transverse pull plate 201 are fixedly connected to two other insulating sleeves 102. In the middle of the transverse pull plate 201, an insulating cover 203 is installed. In the middle of the upper end face of the insulating cover 203, a display screen 202 is fixedly installed. A gasket is provided between the upper end of the insulating cover 203 and the display screen 202. Inside the bottom end of the insulating cover 203, a sealing cover 204 is installed. The insulating cover 203 and the transverse pull plate 201 are fixedly connected by screws. The bottom end of the insulating cover 203 and the sealing cover 204 are threadedly connected. In the middle of the sealing cover 204, a current sensor 205 is provided. Through the display screen 202, it is convenient to display the monitoring values of the pressure sensor 410 and the current sensor 205;

[0037] On the upper end face of the sealing cover 204, a battery 206 is installed. The bottom end of the current sensor 205 penetrates through the middle of the sealing cover 204 and is in close contact with the middle of the transverse pull plate 201. The current sensor 205 and the sealing cover 204 are threadedly connected. The display screen 202, the current sensor 205, and the battery 206 are electrically connected, so that the current sensor 205 can monitor the current on the multi-segment insulating support mechanism 1 in real time through the transverse pull plate 201, avoiding personnel from accidentally touching the live structure.

[0038] In summary, according to the needs of cross protection, the height of the multi-segment insulating support mechanism 1 is adjusted. Specifically, a plurality of insulating sleeves 102 fixedly installed with central support rods 105 are spliced and assembled, so that the metal connecting columns 104 and the connecting sleeves 103 are connected through a plurality of insulating sleeves 102. Furthermore, a plurality of insulating sleeves 102 are linearly arranged along the axis of the metal connecting column 104, and the insulating sleeves 102 and the support base feet 101 are fixedly connected through the metal connecting columns 104. Thus, it is convenient to adjust the height of the multi-segment insulating support mechanism 1. At the same time, both ends of the transverse pull plate 201 are fixedly connected to two of the insulating sleeves 102, so as to facilitate the determination of the distance between the two multi-segment insulating support mechanisms 1;

[0039] The bottom end of the insulating vertical rod 302 penetrates through the connecting cross bar 301 and is assembled with the connecting sleeve 103. The upper end of the insulating vertical rod 302 and the positioning installation strip 305 are assembled through the positioning sleeve 304. Thus, the positioning connection mechanism 3 and the multi-segment insulating support mechanism 1 can be connected. At the same time, through the connecting cross bar 301 and the strengthening frame 303, the installation stability and strength of the insulating vertical rod 302 and the positioning installation strip 305 can be effectively improved, avoiding the shaking of the plurality of elastic wire blocking mechanisms 4 when the size of the multi-segment insulating support mechanism 1 is too high. The plurality of elastic wire blocking mechanisms 4 are installed on the two positioning installation strips 305;

[0040] Specifically, the insulating tank 401 is fixedly connected to the positioning and installation bar 305, and the insulating tank 401 is slidably connected to the horn installation rod 402 through the guide seat 409, the limit cover 404 and the connecting ring 411. The upper end of the horn installation rod 402 is fixedly connected to the horn bent rod 403 through the locking knob 405. Thus, it is convenient to linearly arrange multiple elastic wire blocking mechanisms 4 along the side of the positioning and installation bar 305. When protecting the crossing of the line, the support base foot 101 is fixedly installed. Then, under the support of the multi-section insulating support mechanism 1 and the positioning and connection mechanism 3, the multiple elastic wire blocking mechanisms 4 can lift the line in case of a line fault or dropping in real time. The connecting ring 411 is connected to the guide seat 409 through the support spring 408, so that under the action of the support spring 408, the horn bent rod 403 can be elastically supported through the horn installation rod 402, which is convenient for buffering the dropped line.

[0041] Both ends of the horn bent rod 403 are fixedly connected to multiple anti-disengagement rods 407 through the limit inclined rods 406. Thus, through the horn bent rod 403, the limit inclined rods 406 and the anti-disengagement rods 407, the dropped line can be lifted and limited, avoiding the line from shifting and disengaging from the horn bent rod 403. A pressure sensor 410 is provided at the bottom end of the guide seat 409, so that the pressure received by the horn bent rod 403 can be monitored through the pressure sensor 410, and then the situation of the line dropping can be detected. A current sensor 205 is installed in the middle of the sealing cover 204, so that the current sensor 205 can monitor the current on the multi-section insulating support mechanism 1 in real time through the horizontal pull plate 201. Thus, when the multi-section insulating support mechanism 1, the positioning and connection mechanism 3 and the elastic wire blocking mechanism 4 are in an insulating state, further safety detection can be carried out to avoid personnel from accidentally touching the energized structure.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
