Abstract
The utility model discloses a leak detection system applied to a refuse landfill liner. The leak detection system comprises two vertical support rods, a conductive transverse beam arranged on the upper ends of the support rods, a voltmeter arranged on the conductive transverse beam, conductive fixation seats arranged on the lower ends of the support rods, metal nails arranged on the bottoms of the fixation seats, and conduction lines connecting the conductive transverse beam with the fixation seats. The damaged situation of the liner is timely reflected, and if the value of the voltmeter under normal condition largely changes, the liner can be judged to be broken and the broken part of the liner can be positioned. A plurality of the leak detection systems can be respectively arranged on the fixed positions of a refuse landfill, and when the value of the voltmeter changes, the probable broken position of the liner can be positioned according to the value of the voltmeter. The refuse landfill liner can be divided into many sub areas, and one leak detection system is correspondingly arranged in each sub area, so that the broken part of the liner can be more accurately positioned.
Description
Technical field
The utility model belongs to the technical field of the static state of machine or structure member or the test of mobile equilibrium.
Background technology
Percolate can seriously pollute water source and soil, the effect of refuse landfill pad is that the inside and outside of refuse landfill completely cut off, the discharge of control percolate, make it unlikely clay seam and the underground water of entering, and stop extraneous water to enter landfill yard in order to avoid increase the generation of percolate, thereby reduce the pollution to environment.
What at present refuse landfill pad is adopted is that contamination monitoring well is set near refuse landfill, and the discharge capacity of the change detection percolate by water quality in contamination monitoring well changes, and indirectly judges whether liner has breakage.But there is problem sensitive not and that can not position breakage in this method.Because leachate leaking, in contamination monitoring well, need to pass through the infiltration layer by layer of clay seam and underground water, and this need to pass through a couple of days or longer time, can not reflect in time the damaged situation of liner.Even if adopt and judge in this way refuse landfill pad breakage, do not know the position of breakage yet.
Utility model content
The utility model provides a kind of leak detection system that is applied to refuse landfill pad, with the detection method of contaminated solution monitoring well sensitive not and can not position breakage problem.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of leak detection system that is applied to refuse landfill pad, comprise two cramp bars that vertically arrange, the upper end of two cramp bars is provided with conduction crossbeam, conduction crossbeam is provided with voltage table, the lower end of two cramp bars is provided with the holder of conduction, and the bottom surface of holder is provided with peg, between conduction crossbeam and holder, is connected with wire.
In the surface dust of peg insertion refuse landfill of the present utility model, contact with liner, the upper surface of liner needs metallizing material to form equipotential layer, when external power supply, peg and liner form with closed-loop path, there is larger variation in the numerical value of voltage table under normal circumstances, can judge that liner occurs damaged, compared with prior art, the utility model has the advantage of: 1, more timely to the damaged situation reflection of liner, liner, once generation is damaged, can embody by the numerical value of voltage table; 2, can position breakage, in the fixed position of refuse landfill, arrange respectively several leak detection systems, the corresponding leak detection system of every sub regions, when voltage table changes, in the time of can positioning according to region, has reduced workload widely.
Further, described cramp bar is hollow structure, and described wire is inner through cramp bar hollow, prevents that wire is outside exposed.
Further, described holder is provided with conductor wire, between holder and wire, by conductor wire, connects, and its detected electric signal is more stable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Fig. 1 is the structural representation that the utility model is applied to the leak detection system embodiment of refuse landfill pad.
Embodiment
As shown in Figure 1, a kind of leak detection system that is applied to refuse landfill pad in the present embodiment, comprise the two hollow structure cramp bars 1 that vertically arrange, the upper end of two cramp bars 1 is provided with conduction crossbeam 2, conduction crossbeam 2 is provided with voltage table 3, the lower end of two cramp bars 1 is provided with the holder 4 of conduction, the bottom surface of holder 4 is provided with peg 5, between conduction crossbeam 2 and holder 4, be connected with wire 6, described wire 6 is inner through cramp bar 1 hollow, described holder 4 is provided with conductor wire 7, between holder 4 and wire 6, by conductor wire 7, connects.
The present embodiment is arranged on the several different fixed positions of refuse landfill, and refuse landfill is divided into several sections, the corresponding leak detection system of every sub regions.When mounted, the top layer that peg 5 is inserted to refuse landfill makes the end of peg 5 contact with liner, and the upper surface of liner needs metallizing material to form equipotential layer, when external power supply, and forms a closed-loop path.
For prompting better, on voltage table 3, connect a micro computer 8, on micro computer 8, connect an alarm 9, when the variation of voltage table 3 surpasses the numerical value of regulation, alarm 9 can report to the police to cause by the tinkle of bells staff's attention.
For a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement, these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
