A protective cover 103 is fixed to the side wall of the body 1, and the protective cover 103 is located on the side where the first elastic trigger component 9 is provided.

[0025] The surface of the mounting base 4 is provided with mounting holes 401, which are convenient for fixing it on the upright posts of the substation fence by means of bolts and nuts.

[0026] Working principle: Figure 7 As shown in the figure, D is the device, E is the wire rope, and C is the substation fence of the prior art. The two devices are set on the two upright posts of the substation fence by bolts and nuts. At this time, the state of the universal ball 5 on one side of the first elastic trigger component 9 and the first connecting ring 6 is as shown in FIG. Figure 3As shown, the positioning rod 13 is limited to the position of the first elastic trigger component 9, and then the two ends of the steel wire rope are installed on the first connecting ring 6 of one device and the second connecting ring 7 of another device. At this time, the steel wire rope can play a further blocking role relative to the substation fence. Then the positioning rod 13 is removed. Under the action of the steel wire rope, the first elastic trigger component 9 will not move backward too much. When someone climbs over the substation fence and tries to pull the steel wire rope through, the steel wire rope tilts under the action of pulling, so that the first metal ball 96 contacts the annular pressure sensor 8. When the pressure value exceeds the preset value, the controller controls the alarm to be issued and the alarm signal is remotely transmitted, and the photos taken by the monitoring are remotely transmitted to the remote control center; When someone tries to cut the wire rope, after it is cut, without external force, the second spring 94 pushes the first metal ball 96 to move backward, thereby hitting the vibration transmission component 10, which is detected by the vibration sensor 14 and an alarm is issued; When someone tries to hit and destroy the surveillance camera 3, the third spring 202 plays a certain buffering role under the action of external force, and the surveillance camera 3 will shake when hit, so that the third metal ball 204 contacts the vibration conduction component 10; When someone attempts to dismantle the device, Figure 6 As shown, after the bolts and nuts are removed, when the device is lifted upward, the squeezed pressure block 1105 is released without the action of external force and moves downward, thereby driving the first rack 1102 to move upward, causing the second metal ball 1106 to hit the vibration conduction component 10, thereby triggering an alarm. At the same time, when the pressure block 1105 is released and moves downward, it drives the second rack 1103 to move downward, causing the connecting plate 1201 to move downward, and the piston rod squeezes the liquid storage cylinder 1202 to spray out the liquid in the liquid storage cylinder 1202.
