Abstract

A remote monitoring device incorporating a conductive polymer fuse capable of detecting chemical contamination or hazardous chemicals within environments local to potential leak sites. The invention is tuneable to different chemicals (specific contaminants) and with changeable sensitivity, easy to fit and simple to use, with an audible/visual alarm, which can also be sent via SMS to remote monitoring stations.

Description

DESCRIPTION
CONDUCTIVE POLYMER FUSE MONiTORING DEVICE This invention relates to a system capable of detecting the presence of hazardous chemicals where there is a likelihood of chemical leakage.
Contamination of land, drainage and running water is a serious issue and in 1999 accounted for over 5000 pollution incidents in England. There are several statute and guidelines which impose strict standards for preventing pollution and harsh penalties for causing it. The government has tasked DEFRA to continually reduce pollution incidents and it is made clear that prevention is preferred to cure, as such companies need to access effective monitoring equipment.
There are existing methods of leak detection, the simplest being a visual inspection of the area although this can only apply where access can be gained and is costly in personnel. Monitoring the inputloutput of the product also occurs but this method is susceptible to inaccuracies. More complex cable systems are also available which are laid around sites and connected to alarm systems but suffer from high installationlservice costs reusability and complexity.
This new invention relates to a simple, easy to install, fast reacting, remote monitoring device. The device is fitted with a chemical fuse capable of detecting hazardous chemicals within the environment, local to potential leak sites. When the contaminant affects the monitoring device adversely an alarm is triggered thereby alerting the site personnel. The device body may also have the capability to be extended thereby allowing different depths to be monitored and also bore holes or surface water layers.
Features that may be incorporated into the system may include audible alarm, visual alarm; SMS alarm system and connection to remote remediation techniques. The system could be tuned to different hazardous chemicals types and also the speed of response could be altered.
Additionally the incorporation of several different detecting elements in one monitoring device to detect several different chemicals at the same time. The use of a range of sensitivities could also be used to give a traffic light system to the device. The system would incorporate a method whereby it would allow the system to be reused into different areas.
The invention will now be described by way of example and with reference to the accompanying drawings in which: -Figure 1 represents the monitoring device.
Figure 2 represents detail of the conductive polymer chemical fuse.
In figure 1, a rechargeable battery and electronic circuitry are used as a power source and control for the unit. The battery utilises a solar cell, 7, to recharge the battery. This battery provides power for a circuit, which includes the conductive polymer fuse, 3. If this breaks an LED/audible alarm, 6 and a SMS signal, 2, are triggered. The sensor pod body, 5, is inserted into the ground so that the body, 4 is below ground.
Figure 2 shows detail of the conductive polymer fuse at the tip of the sensor pod, which is inserted into the ground. The tip, 10, will be a porous spike to allow the contaminant through to the porous layer, 9, at the bottom of the pod above the spike. The contaminant is drawn into contact with the conductive polymer fuse, 3, by a wicking material, 8, which will draw the contaminant in from the surrounding area.
