Outer one end is connected with bracing wire 7.Guard box 1 is used to carry other components of landslide pantograph, prevents rain erosion or sunlight sudden and violent
Solarization damages, and waits displacement detectors for detecting the change in displacement situation of monitoring point when geology changes, thus over the ground
Matter disaster carries out early warning, and battery 2 is the power supply of displacement detector, and setting GPS device 3 can accurately determine the position of monitoring point
Information.The device of usually used displacement detecting is drum stay-supported, is measured by apron drawing, the position in the present embodiment
It moves detection device and detects change in displacement using the method for measuring different electric currents, stretched including casing 4, the sliding slided in casing 4
Contracting body 5 and be fixed on the touch switch 6 abutted on 4 inner wall of casing and with sliding extension body 5, sliding extension body 5 outwardly one
End is connected with bracing wire 7,7 stress of bracing wire when geology moves, by pulling bracing wire 7 to drive sliding extension body 5 sliding in casing 4
It is dynamic, touch switch 6 is fixed on the inner wall of casing 4, sliding extension body 5 just contacts in sliding process with touch switch 6, leads to
It crosses sliding extension body 5 and slides the different touch switch 6 of touching in casing 4, so that the circuit of a closure is formed, according to resistance
With the relationship of the length of conductive material, the corresponding different size of electric current of the touch switch 6 of different location, therefore the moving long of bracing wire 7
Degree can be calculated according to electric current, then obtain the misalignment of geological movement.
It further include the cable 8 being connect with touch switch 6 in the present embodiment, the other end of cable 8 is connected with converter 9, turns
Parallel operation 9 is by data line 10 and external connection, and by converter 9, sliding extension body 5 is slided to generation in casing 4
Electric signal is transformed into digital signal, corresponding threshold value of warning can be arranged according to the situation in different monitoring areas, when displacement occurs
Variation, when reaching early warning position, sliding extension body 5 triggers the touch switch 6 of corresponding position, and electric current changes, corresponding
Digital signal also changes, and reaches the threshold value of setting, issues warning information, reminds the risk that geological disaster may occur, from
And so that related personnel is taken action as early as possible and avoid that accident occurs.
Multiple touch switch 6 are angularly surrounded on 4 inner wall of casing in the present embodiment, forming layer touch switch, and layer touches
Switch it is equidistant be arranged in 4 inner wall of casing vertically, the layer touch switch of outermost end is initial position touch switch 61.Cable 8
