[0026] With the crust movement and the loss of groundwater and other natural phenomena, the frequency of the road surface subsidence under the road is increasing, and the road surface collapse pit often occurs, which leads to the situation of vehicle falling, so in order to deal with this situation, it is necessary to detect the subsidence degree of the road and the road surface under the road frequently, reduce the collapse situation, but the traditional detection is mostly workers using level gauge to measure along the road, which not only takes a long time but also consumes a lot of labor, and the measurement can only obtain the current subsidence amount and cannot achieve early warning.

[0027] When actually used, first detection rod 4 is first pulled out along first rotating part 3, and second detection rod 41 is pulled out along second rotating part 31, then the device is placed along the road before paving asphalt on the road surface, and then the asphalt is directly paved on the road surface, at this time the asphalt will bury the device, and after the asphalt paving is completed, a road roller is still needed to roll the asphalt to make the asphalt road flat, when the road roller passes above the device, the device at this position is in working condition to monitor in real time, when settlement occurs at a certain place on the road surface, first detection rod 4 and second detection rod 41 will rotate due to ground deformation, thereby driving first rotating part 3 or second rotating part 31 to rotate, first sliding groove 33 and second rotating part 31 can drive first angular displacement sensor 7 or second angular displacement sensor 8 to work when rotating, thereby first angular displacement sensor 7 and second angular displacement sensor 8 can convert the angle of rotation of first detection rod 4 and second detection rod 41 into an electrical signal and transmit it to controller 13, a preset action threshold is set in controller 13, and the electrical signal input by first angular displacement sensor 7 and second angular displacement sensor 8 is compared, when the electrical signal input by first angular displacement sensor 7 and second angular displacement sensor 8 is greater than the preset action threshold, controller 13 controls electrically controlled switch 15 to close, and then controller 13 sends a warning signal to the outside through the internal signal sending module at this time, because the device is installed under the road, considering that the signal transmission is limited, a signal transceiver should be arranged at a position such as a guardrail or a telegraph pole near the device, the signal transceiver has the functions of amplifying electromagnetic signals and transmitting electromagnetic signals to a nearby computer terminal, so as to ensure the stability of signal transmission, first angular displacement sensor 7 and second angular displacement sensor 8 are connected in parallel across electrically controlled switch 15 and controller 13, first angular displacement sensor 7 is connected in series with first balancing resistor R1, and second angular displacement sensor 8 is connected in series with second balancing resistor R2, first balancing resistor R1 and second balancing resistor R2 are both used for balancing circuit current, preventing electrically controlled switch 15 and controller 13 from being locally short-circuited, when the threshold is not exceeded, electrically controlled switch 15 can be opened to disconnect the circuit and reduce power consumption, thereby ensuring that the device has sufficient electrical energy for warning when warning, thereby the device can monitor the road surface in real time and continuously, and when the road settlement exceeds the threshold, it can also accurately know which section of the road has the risk of collapse, without the need for manual measurement along the road, greatly reducing the detection time, and the whole road settlement can be warned in time.

[0028] The input end of the first angular displacement sensor 7 and the second angular displacement sensor 8 is rotatably provided with a center rotating rod 71, the two center rotating rods 71 are respectively located between the first angular displacement sensor 7 and the first rotating part 3 and between the second angular displacement sensor 8 and the second rotating part 31, a first push block 74 is slidably sleeved on the center rotating rod 71, the first angular displacement sensor 7 and the second angular displacement sensor 8 are fixedly provided with a mounting plate 72, a torsional spring 73 is fixedly connected between the mounting plate 72 and the first push block 74, a plurality of electric push rods 721 are fixedly installed on the mounting plate 72, and one end of the electric push rod 721 away from the mounting plate 72 is movably clamped on the side surface of the first push block 74. One side of the first push block 74 is provided with a limiting frame 77, a second sliding groove 771 is formed in the middle of the limiting frame 77, the side of the first push block 74 close to the limiting frame 77 is integrally formed with a clamping block 75, and the clamping block 75 is attached to the surface of the limiting frame 77 in the initial state. The connecting rod 78 is slidably installed on the partition plate 11, the end of the connecting rod 78 close to the limiting frame 77 is integrally formed with a stop block 781, the stop block 781 is slidably clamped in the second sliding groove 771, and the stop block 781 is used to block the clamping block 75. The upper side of the mounting shell 1 is provided with a pressing plate 2, the lower surface of the pressing plate 2 is fixedly provided with a sliding block 21, the sliding block 21 is slidably clamped in the inner part of the upper chamber, the upper surface of the partition plate 11 is fixedly provided with a piezoelectric ceramic 6, the end of the connecting rod 78 away from the center rotating rod 71 is fixedly installed on the sliding block 21, and the sliding block 21 and the partition plate 11 are fixedly connected with a plurality of evenly distributed elastic blocks 16.

[0029] When the device is in the initial position, the block 781 is inside the second chute 771, and the block 75 is blocked by the block 781 under the action of the torsional spring 73. When the device is placed on the roadbed, then the asphalt fills the device, and the asphalt will bury the device. When the road roller rolls over the device, the elastic block 16 is deformed under the action of the road roller. At this time, the sliding block 21 drives the connecting rod 78 to descend, and the block 781 will slide out of the inside of the second chute 771. At this time, the block 75 is released, and the first push block 74 is pushed to adhere to the side surface of the first rotating part 3 or the second rotating part 31 under the action of the torsional spring 73. At this time, the first push block 74 will be driven to rotate by the first rotating part 3 or the second rotating part 31. When the road surface subsides, the first detection rod 4 or the second detection rod 41 in the subsidence direction will be driven to rotate. When the subsidence amount exceeds the warning value, the first rotating part 3 and the second rotating part 31 rotate by a certain angle, and the controller 13 continuously transmits an alarm to the outside. When the staff arrives at the warning position, the remote control can be used to work the electric push rod 721 at the corresponding position after the road is treated. The work of the electric push rod 721 will pull the first push block 74 to move. At this time, the first push block 74 will be separated from the first rotating part 3 or the second rotating part 31. The first push block 74 is driven to rotate by the torsional spring 73 until the block 75 is blocked by the limiting frame 77. At this time, the first push block 74 drives the center rotating rod 71 to rotate, thereby making the reading of the first angular displacement sensor 7 zero and eliminating the alarm. The limiting frame 77 can prevent the first push block 74 from rebounding beyond the initial position, ensuring that it can be stably stopped at the initial position. When the reading is zeroed, the electric push rod 721 is controlled again to push the first push block 74 to adhere to the first rotating part 3 or the second rotating part 31. At this time, the subsidence warning can be restarted. When the subsidence amount exceeds a certain threshold, the alarm will be restarted again, so that the device can be reused to continuously monitor the road subsidence at the position.

[0030] The piezoelectric ceramic 6 can generate a voltage difference and in turn generate an electric current according to the change in pressure. When a vehicle passes over the road surface, it will generate pressure on the road surface at that position. Especially when some large buses and trucks pass by, the road surface will produce a certain elasticity, especially the asphalt road surface, which has a larger elastic deformation. Therefore, when the vehicle passes, the lower pressure plate 2 is extruded by the asphalt, and in turn the pressure plate 2 pushes the sliding block 21 to extrude the piezoelectric ceramic 6, thereby generating an electric current. The piezoelectric ceramic 6 is connected in parallel across the two terminals of the storage battery 14, and the piezoelectric ceramic 6 is connected in series with a diode VD. In turn, when pressure is generated, the piezoelectric ceramic 6 will generate an electric current and unidirectionally deliver it to the storage battery 14. With the continuous passage of vehicles above, the storage battery 14 can be continuously charged, thereby meeting the electrical energy required for the operation of the device.

[0031] The middle part of the first rotating member 3 is provided with a central groove 32, and one side of the first rotating member 3 is provided with a first sliding groove 33 communicated with the central groove 32, and one side of the first rotating member 3 close to the first angle displacement sensor 7 and one side of the second rotating member 31 close to the second angle displacement sensor 8 are both provided with a plurality of groove bodies 34 uniformly distributed, and one end of the first push block 74 close to the first rotating member 3 or the second rotating member 31 is integrally formed with a plurality of convex teeth 76 corresponding to the groove bodies 34.

[0032] When the first detection rod 4 and the second detection rod 41 are extracted, at this time, the first detection rod 4 and the second detection rod 41 pass through the first sliding groove 33 until the shaft rod 42 enters the inside of the central groove 32, when the first detection rod 4 or the second detection rod 41 rotates, the first rotating member 3 or the second rotating member 31 is driven to rotate, when the first push block 74 is pushed, the convex teeth 76 can cooperate with the groove bodies 34 to be clamped.
