Floater variable resistance sensing type tunnel ponding warning device

Abstract

The invention discloses a floater variable resistance sensing type tunnel ponding warning device which comprises a float chamber, wherein through holes in upper and lower ends of the float chamber are covered with filter screens, a floater is arranged at the bottom of the float chamber, the floater is wrapped with a magnetic material, a varistor clings to the scale value part of the float chamber, a variable resistance wire is fixedly mounted inside the varistor, and the variable resistance wire is sleeved with a magnetic variable resistance slip ring. The invention provides a prewarning and displaying device for ponding conditions occurring inside unattended tunnels and culverts, and before a vehicle enters the tunnels and the culverts, prewarning and state displaying to the ponding conditions inside the tunnels and the culverts can be given in a full position, so as to remind a vehicle driver. Therefore, road traffic accidents caused by ponding in tunnels and culverts can be avoided, the problems in traffic and road safety, caused by ponding on traffic roads provided with tunnels and culverts can be effectively solved, and traffic road running safety is enhanced.

Description

technical field [0001] The invention belongs to the field of traffic and road safety, and relates to a tunnel and culvert water accumulation safety warning technology, in particular to a float variable resistance sensing type tunnel water accumulation warning device. Background technique [0002] In recent years, due to the increasing shortage of land resources and the problem of traffic road safety, three-dimensional traffic roads and urban rail transit have begun to move towards speed and diversification. In various traffic roads, efficient utilization of underground space has become the goal of development and competition. At present, various tunnels and culverts have become new ways of urban road traffic development. [0003] In traffic roads, in order to solve the problem of cross road traffic congestion, a large number of underground road structures such as tunnels and culverts are designed and adopted. In urban rail transit, in order to save ground land resources, ...

AI Technical Summary

Problems solved by technology

[0004]At present, the situation of water accumulation in tunnel roads is mainly inspected by personnel. Road inspectors cannot conduct investigations in a timely manner; second, underground roads such as tunnels and culverts, where vehicles pass, are in harsh conditions and the environment is dangerous; third, water accumulation in underground roads such as tunnels and culverts cannot give real-time warnings, affecting road traffic and causing traffic safety hazard
