when the pressure value of the groundwater is detected, the first water permeable hole 111, the third water permeable hole 221 and the second water permeable hole 211 are communicated in sequence, so that the groundwater is separated out from the first water permeable hole 111, the third water permeable hole 221 and the second water permeable hole 211 to extrude the first diaphragm 370, the first diaphragm 370 transmits the pressure to the first pressure sensor 350 through a liquid pressure guide medium, and the first pressure sensor 350 detects the pressure value of the groundwater around the shell 100; the fourth water permeable hole 112, the sixth water permeable hole 222 and the fifth water permeable hole 212 are sequentially communicated, so that the underground water can be separated from the fourth water permeable hole 112, the sixth water permeable hole 222 and the fifth water permeable hole 212 to extrude the second membrane 380, the second membrane 380 transmits pressure to the second pressure sensor 360 through a liquid pressure-guiding medium, and the second pressure sensor 360 detects the pressure value of the underground water just opposite to the shell 100.
After the first pressure sensor 350 and the second pressure sensor 360 detect the pressure of the groundwater, the compensation module compensates the pressure weakened by the deformation of the first diaphragm 370 and the second diaphragm 380, so that the pressure value obtained by the main control module is closer to the actual pressure value of the groundwater. The main control module and the display module can be arranged in an emergency prevention and control center, after the signal transmission of the first transmission module is carried out, the main control module can obtain the actual pressure value of underground water, if the pressure of the underground water exceeds the standard, the display module can directly display the emergence place of the leakage accident to emergency personnel in the emergency prevention and control center, and the emergency prevention and control center can send the emergency personnel to remedy before the leakage accident happens, so that the probability of the leakage accident is reduced. Meanwhile, the second transmission module transmits the alarm signal to the alarm module, and the alarm module sends out the alarm signal, so that the organization personnel of the subway station organize the staff in advance and evacuate passengers in advance, and the probability of casualties caused by leakage events is reduced.
When the first pressure sensor 350 and the second pressure sensor 360 are maintained, the end cover 240 is dismounted, the screw 320 is rotated, the support frame 310 is not abutted against the outer peripheral surface of the sealing shell 210, the sealing shell 210 is rotated, the first water permeable hole 111 is not communicated with the third water permeable hole 221, the fourth water permeable hole 112 is not communicated with the sixth water permeable hole 222, and therefore the probability that underground water permeates into the ground drop station is reduced; the support frame 310 may then be withdrawn and the first pressure sensor 350, the second pressure sensor 360, the first diaphragm 370, and the second diaphragm 380 serviced or replaced.
The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: equivalent changes made according to the structure, shape and principle of the invention shall be covered by the protection scope of the invention.
