[0041] The main function of the intelligent grounding wire grounding terminal clamp is to form a good grounding connection by fixing the conductor end clamp 3 on the pole tower angle steel 2 and connecting it with the intelligent grounding wire conductor end clamp fixed on the conductor of the transmission line. A monitoring alarm device 1 is fixed on one side of the grounding terminal clamp 6. 1 Working principle of the grounding terminal clamp 6: The clamp clamps the tower angle steel by driving the opening and closing of the movable clamp to realize the installation and removal of the grounding terminal clamp. 2 Monitoring principle of the operation status of the grounding terminal clamp 6: A retractable elastic contact is set on the bottom surface of the pole tower angle steel 2 clamped by the grounding wire clamp 6 as a collection device of the intelligent monitoring alarm device. The pressure value generated by the contact between the retractable elastic contact and the side of the pole tower angle steel 2 is used to detect whether the grounding terminal clamp is normally connected to the pole tower angle steel 2, and whether there is loose displacement between the grounding terminal clamp 6 and the pole tower angle steel 2. The retractable elastic contact feeds back the information to the sensor of the intelligent monitoring alarm device, and sends it to the background terminal in real time through the 4G wireless communication module. At the same time, the sensor also forms a closed loop with the control panel. After the power of the device is started, once the power of the device is suddenly cut off or the power of the device is cut off by human damage, the device alarm will be triggered to detect and judge whether there is an abnormality in the device. By adopting the above technical solution, the alarm device has the function of immediately triggering the device alarm once the ground wire is stolen or the ground wire is loose or falls off, or the alarm device is powered off or mistakenly dismantled by personnel.

[0042] Working principle of the wire end:

[0043] The wire end clamp 3 is hung on the wire and removed from the wire by pulling the insulating rope 7. The insulating traction rope 7 pulls the wire end clamp close to the wire, aligns the wire entry of the clamp with the wire, and pulls it upward to hook the wire end clamp hook on the wire, that is, the work of hanging the wire end clamp into the wire is completed, thereby achieving the purpose of grounding. When the grounding operation is completed and the conductor end clamping jaws need to be removed, it is only necessary to tighten the insulating rope to a vertical state, and then pull the insulating rope upward instantly by hand. At this time, the conductor end clamping jaws are pulled upward by the traction force of the insulating rope, and the lower clamping seat moves downward a certain stroke. During the downward movement of the lower clamping seat, the flexible steel wire ropes on both sides of the lower clamping seat are simultaneously driven to move downward, and the unlocking gears on both sides of the flexible steel wire rope are linked to synchronously rotate counterclockwise by a certain angle. At the same time, the unlocking gears on both sides drive the engaged left and right outer clamping jaws to rotate clockwise by a certain angle. The fork track shafts on the left and right outer clamping jaws contact the left and right clamping jaws wire plates during the clockwise rotation of the clamping jaws. The fork track shafts on both sides press the left and right clamping jaws wire plates to also swing clockwise by a certain angle. The guide grooves of the left and right clamping jaws wire plates are slidingly connected to the left and right clamping jaws. At this time, the left and right clamping jaws wire plates swing and also drive the left and right clamping jaws to rotate synchronously clockwise by a certain angle. Through the above synchronous action, the left and right outer clamps can be opened synchronously with the left and right clamps to a certain angle so that the clamped wire can be smoothly separated from the clamps, thereby achieving the purpose of removing the grounding wire.

[0044] Intelligent monitoring and alarm device

[0045] Main components:

[0046] (1) Resistive pressure-sensitive sensor: The resistive pressure-sensitive sensor is installed on the wire clamp at the conductor end and the grounding end respectively to realize real-time monitoring of the clamping force of the wire clamp. By real-time detection of the clamping force threshold of the wire clamp, it is determined whether the wire clamp is loose, hanging in vain or removed, thereby realizing full-process monitoring of the wire clamp at the conductor end and the grounding end.

[0047] (2) Battery management board - provides working power for the alarm device, which can work continuously for more than half a month.

[0048] (3) Internet of Things 4G wireless communication module - provides data transmission and auxiliary positioning services. The alarm information can be sent to the cloud platform and sent to the backend in the form of SMS, WeChat or phone call.

[0049] (4) Power switch: controls the start and stop of the alarm device.

[0050] (5) Housing: It should be waterproof to a certain extent and equipped with a charging plug to ensure that the alarm device can work normally in outdoor environments.

[0051] Working principle:

[0052] Install the alarm device: take the monitoring alarm device 1 to the position where the pole tower angle steel 2 is to be installed, install the angle steel fixing seat 103 on the pole tower angle steel 2, turn the rotating handle 102 to drive the fixing screw 111, and use the thread locking force to drive the movable pressing block 107 to fix the pole tower angle steel 2. The end 110 is squeezed by the movable pressing block 107, and the alarm device is activated;

[0053] Connection of the grounding terminal: Before installation, the operator holds the insulating traction rope 7, hooks the triangular ring 307 on the fixed end 306 of the grounding wire, manually opens the closing device 304, puts the device from top to bottom to the bottom of the overhead line conductor 4, and then lifts it upward. The overhead line conductor 4 enters the inside of the device. At this time, the closing device 304 closes automatically, and the swing arm 308 clamps the grounding wire by the force of the second torsion spring 309 to complete the connection. The striker 312 at the monitoring and alarm device 1 is squeezed by the swing arm 308 and moves toward the receiver 310. After receiving the signal, the second control terminal 311 sends a signal to the monitoring and alarm device 1;

[0054] Unlocking the grounding end: the operator loosens the insulating traction rope 7 to separate the triangular ring 307 from the fixed end 306 of the grounding wire, then lifts the insulating traction rope 7 upward to rotate the device 180°, and continues to pull up the insulating traction rope 7 to open the locking block 302. At this time, the overhead line conductor 4 can be separated from the device.
