Description
Technical field
The utility model relates to a kind of monitoring and early warning sensing device, particularly relates to passive protection net pressure-reducing ring sensing device.
Background technology
At present, the interception massif falling rocks so passive protection net system is widely used, with the impact harm reducing the landslide of geology unstable region, falling rocks causes for road traffic, house, Artificial facilities etc.Its principle of work is substantially all: when there being the dangerous situation such as landslide, falling rocks to occur, and the interception of passive protection net stops the danger such as mudflow, falling rocks, slows down its impact to road traffic, building fixture, simultaneously stability impact kinetic energy.Even if in extreme circumstances, the huge kinetic energy during landing of the danger such as mudflow, falling rocks causes passive protection network loss to ruin, but protection network also Absorbable rod fall most of impact kinetic energy, thus by the impact of danger harm minimize.But in disaster prevention system, because sensor device general at present can not be applied to the monitoring of passive protection net, do not ruin for passive protection network loss the device carrying out monitoring, when dangerous generations such as massif falling rocks, passive protection net damage situations cannot be controlled the very first time, the monitoring of passive protection net is still belonged to blank.
Summary of the invention
In order to realize the monitoring demand to passive protection net damage situations, for above-mentioned technical matters, the utility model proposes a kind of new pressure-reducing ring deformation sensor, be applied to the monitoring of passive protection net, and be convenient to lay in passive online installation, this sensing device stability is strong, highly sensitive and environmental suitability strong, can reflect passive protection net damage situations accurately.
The technical solution adopted in the utility model is: passive protection net pressure-reducing ring deformation sensor described in the utility model is made up of sensor, permanent magnet and mounting part part, the corresponding setting in use of wherein said sensor and described permanent magnet.
Further, describedly to be fixedly installed by described mounting part part position by sensor and described permanent magnet, magnetic flux between described sensor and described permanent magnet is fixed, when between described sensor and described permanent magnet, position sends and changes, the magnetic flux between described sensor and described permanent magnet changes and triggers described passive protection net pressure-reducing ring deformation sensor and reports to the police.
In the utility model, by being installed on the setting of the corresponding sensor of on passive net pressure-reducing ring a pair and permanent magnet, Real-Time Monitoring is positioned at the permanent magnet position on body.When the impact energy that passive net absorbs acts on pressure-reducing ring, pressure-reducing ring ring body shrinks, there is respective change in the permanent magnet position be fixed on ring body, magnet is when electromagnetic inductor, in inductor, magnetic flux strengthens rapidly, and closed internal circuit, export a path signal, complete a trigger alarm thus.Electromagnetic inductor closes that the corresponding time is short, and induction sensitivity is high, for large quality, high speed impact event, also can accurately catch.The utility model is that electromagnetic inductor adds device protection assembly, ensure that sensor operating mode when being subject to impacting is normal, structural integrity.
Actual effect of the present utility model is, grasps passive protection network loss ruin situation by monitoring pressure-reducing ring deformation quantity, has filled up the monitoring of passive protection net blank, and perfect roadbed equipment monitoring system, makes the extension of geologic hazard monitoring and early warning technology apply more extensive.
