Embodiment Construction

[0011] Find a fixed position (10) near the potential debris flow area (9) to place the fixed box (1). If the soil at the fixed position (10) is not solid enough, the base for installing the fixed box (1) must go deep into the hard rock formation below. It must be guaranteed that there is a mudslide in other places under heavy rain, and the fixed box (1) will not move. Find a monitored object (8) that is prone to displacement due to external force in a potential debris flow area (9). If there is no suitable monitored object (8), a monitoring post can be set up. Fix one end of the pull rope (7) on the object to be monitored (8) or on the monitoring stake, and connect the other end to the pull on the disposable vacuum chamber type (pull pressure) contactor (2) in the fixed box (1). Ring (16).

[0012] When the rainfall is too large, the mud-rock layer in the potential mud-rock flow area (9) will be displaced under the action of rainwater and gravity, and the monitored object (8...

Abstract

The invention relates to a displacement monitoring safety warning system being mainly composed of a fixed box, a power supply, a disposable vacuum chamber type (tension / pressure) contactor, a detection switch, a working line, a stay cord, and an alarm device. One end of the stay cord is fixed to an object needing monitoring and the other end is fixed to a tension ring of the disposable vacuum chamber type (tension / pressure) contactor in the fixed box. When the object needing monitoring makes displacement under the external force effect, the stay cord pulls the tension ring to enable two contacts on the working line in the disposable vacuum chamber type (tension / pressure) contactor to be connected. After connection of the two contacts on the working line, the working line is connected and thus the alarm device starts working to carry out alarming. The displacement monitoring safety warning system has advantages of reliable performance, wide application range, high adaptability, great convenience in installation, low cost, simple structure, simple principle, long maintenance period, low cost of use, and low maintenance cost and serves as an effective displacement monitoring and alarmway suitable for large-area promotion.

Description

technical field [0001] The invention relates to a displacement monitoring safety warning system. Displacement of objects under the action of external force is a very normal physical phenomenon, but displacement often brings disasters and safety accidents (debris flows, landslides, landslides, objects falling from heights). In the current human life and production, disasters and accidents often occur due to the displacement of objects due to external forces. Although we cannot prevent disasters from happening, we should be able to warn people before disasters happen. (Imagine the night of heavy rain in Zhouqu County, Gansu Province on August 7, 2010. If there is a displacement monitoring safety warning system on the barren hillside where the debris flow occurs, the alarm will be issued at the initial stage of the debris flow, and people will win valuable Escape time, how many lives can be saved?) Even if this alarm can only win a very short escape time for people, it is also v...
