Abstract
The utility model, which belongs to the field of the coal mine safety detection equipment technology, particularly relates to a resistance-type minded-out water accumulation detecting instrument. Therefore, defects of single detection means for water accumulation in a minded-out region, high instrument requirement, high cost and limited application range and the like in the prior art can be overcome. The technical scheme employed by the utility model is as follows: the resistance-type minded-out water accumulation detecting instrument comprises a housing; a plurality of water flow holes are arranged on the surface of the housing; and one end of the housing is provided with a screwed joint. Two metal sheets with protruded grooves are arranged inside the housing; one ends of the metal sheets are connected with one end, approaching the screwed joint, of the housing and the other ends thereof are not contacted with the housing; leads that are respectively connected to the metal sheets pass through the housing and are connected with a resistance instrument. Besides, hydrophilic expansion glues are arranged in a gap between the metal sheets and the housing. According to the utility model, the provided detecting instrument has advantages of simple structure, low cost, small workload and wide application range.
Description
Technical field
The utility model belongs to mine safety checkout equipment technical field, is specifically related to a kind of resistance-type and adopts sky ponding detection instrument.
Background technology
Adopting that sky ponding surveys is one of necessary means of avoiding occuring the accident such as permeable, can effectively detect the sky ponding situation of adopting.At present, adopt sky ponding and survey the main physical prospecting means that rely on, when particularly creep at the angle of depression in long prospecting bit hole, as adopt sky ponding situation and hydraulic pressure not quite then can't be differentiated goaf ponding situation, whole detection process is had relatively high expectations to detection instrument, also causes whole detection cost high.
Summary of the invention
The utility model is single mainly for present goaf ponding detection means, instrument requires high, the shortcomings such as cost is high, restricted application, provides a kind of resistance-type simple in structure, that cost is low, workload is little, applied widely to adopt sky ponding detection instrument.
The technical scheme that the utility model is taked for achieving the above object is:
A kind of resistance-type is adopted sky ponding detection instrument, comprise housing, wherein: described surface of shell offers some discharge orifices, end at described housing is provided with threaded connector, in housing, be provided with two with the sheet metal of tongue, one end of sheet metal is connected with the end of housing near threaded connector, the other end of sheet metal does not contact with housing, on each sheet metal, respectively connect a wire, described wire passes housing and is connected with the resistance instrument, is provided with water-swellable glue in the space between sheet metal and housing.
The utility model adopts technique scheme, when adopting sky ponding, after detection instrument enters the goaf by boring, if there is ponding in the goaf, after detection instrument did not have in the entry, water entered space between detection instrument tube wall and the sheet metal by the aperture on the detection instrument tube wall, collided by two sheet metals of volumetric expansion compressing after water and expansion glue meet, the generation current loop, there is ponding in surperficial goaf; After detection instrument entered the goaf, if there is not ponding, the expansion glue volume remained unchanged, and then two sheet metals can not be collided, can not the generation current loop, show that position that the goaf is surveyed is without ponding.
