[0032]

[0033] As can be seen from the above, the micro silicon piezoresistive pressure sensor provided in the device is helpful for understanding the damage to the bunker and the injuries of the people inside the bunker. At the same time, the control box 2 provided can transmit the damage to the bunker and the injuries of the people inside the bunker to the server in a timely manner.

[0034] Working principle: When using the device, the operator first places the curved plate 28 on the rotating ring 30 and the square block 38 on the supporting block 37, and then drives the first screw 5 to rotate by rotating the first supporting column 8. Since the first screw 5 and the first top seat 31 cooperate with each other and are connected, the first screw 5 is fixedly connected to the first top seat 31. When the first screw 5 is fixedly connected to the first top seat 31, the operator manually places the connecting block 40 fixedly connected on the curved plate 28 inside the through-holes opened on both sides of the first baffle 1, and uses the first baffle 1 to be fixedly connected to the first top seat 31, thereby limiting the position of the curved plate 28. When the first screw 5 is fixedly connected to the first top seat 31, the operator can stop rotating the first supporting column 8. At this time, the curved plate The connecting block 40 provided on 28 is located inside the through hole opened on the first baffle 1, so that the arc plate 28 and the first baffle 1 are relatively fixed, and the first baffle 1 is fixedly connected to the first top seat 31, thereby making the arc plate 28 and the first top seat 31 relatively fixed, and then the second support column 33 can be rotated. Since the second support column 33 is fixedly connected to the second screw 34, the rotation of the second support column 33 drives the rotation of the second screw 34, and the second screw 34 is matched with the second top seat 35 to be connected, so that the second screw 34 is fixedly connected to the second top seat 35, and in the process of the second screw 34 and the second top seat 35 being fixedly connected, since the square block 38 is placed on the support block 37, and the support block 37 is rotatably connected to the second screw 34, the second screw 34 is fixedly connected to the second top seat 35. During the process of fixed connection between the second screw rod 34 and the second top seat 35, the support block 37 moves toward the side close to the second top seat 35. Since the square block 38 is placed on the support block 37, the support block 37 moves toward the side close to the second top seat 35, so that the square hole opened at the center of the square block 38 cooperates with the second top seat 35, so that the second top seat 35 and the square block 38 are relatively fixed. Subsequently, the central axis of the second support column 33 and the central axis of the first support column 8 can be made perpendicular to the horizontal plane, even if the first support column 8 and the second support column 33 are placed on the ground and fixedly connected to the ground, the splicing plates can be manually spliced ​​to form the top plate 3, and then the top plate 3 and the connecting plate 4 are connected. The top plate 3 and the connecting plate 4 are spliced ​​together, and at the same time, the clamping rod 32 fixedly connected to the arc column 27 is located inside the clamping hole opened on the top plate 3. Then, the protective tube 21 is pushed to move by manually rotating the nut block 18. Since the retaining ring 23 fixedly connected to the protective tube 21 fits with the moving tube 24, the rotation of the nut block 18 is used to make the protective tube 21 push the moving tube 24 to move on the arc rod 22. Since the L-shaped rod 26 is fixedly connected to the moving tube 24, the L-shaped rod 26 is engaged with the clamping block 25, and then the clamping block 25 and the L-shaped rod 26 are relatively fixed, even if the top plate 3 and the L-shaped rod 26 or the moving tube 24 are relatively fixed, thereby completing the limiting work of the top plate 3, and then the detector body 13 is adsorbed on the moving tube 24.The side cover composed of the top plate 3 and the two ends of the ceiling composed of the connecting plate 4 are placed inside the connecting seat 36. Since the side plate 6 and the bottom plate 12 are connected by a right-angle hinge, the bottom plate 12 is then placed inside the ceiling, and the control box 2 is placed inside the ceiling. The fastening rod 10 is then passed through the mounting hole opened on the bottom plate 12 and fixedly connected to the ground, so that the bottom plate 12 is fixedly connected to the ground, thereby completing the assembly process of the device. When using the device, the device can be attacked by firepower, and during the attack, the detector body 13 provided can be used to detect damage to the device. The device can then be used to monitor the damage to the device and the injuries to the personnel within it. The control box 2 can then be used to transmit the damage to the device and the injuries to the personnel within it to the server. When using the device to counterattack, the user can manually rotate the fastening screw 17 to separate it from the support rod 7. The support rod 7 can then be pushed to swing the second baffle 9. When the side of the second baffle 9 is parallel to the horizontal plane, the fastening screw 17 can be rotated to securely connect it to the support rod 7. The user can then use the weapon to counterattack using the through hole created by the swinging of the second baffle 9 as a visual line of sight to the outside world.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
