Abstract
The utility model relates to a tri-dimensional array natural electromagnetic detector, which comprises a spherical cap-shaped tray and a flat capacitance sensor array distributed on the spherical cap-shaped tray, wherein the flat capacitance sensor comprises two covering copper plates with an equal size whose copper platinum surfaces correspond two by two. An insulating layer is equipped between the two copper platinum surfaces, and a metal screening cover is provided on the exterior of the two covering copper plates. The flat capacitance sensor is a natural electromagnetic sensor and is equipped in a spherical cap shape, thereby can extend to the earth and enlarges to detect with the spherical cap to realize tri-dimensional detection. This detector can remote detect objects far away without under-well installation, and simultaneously it can collect information of integral stress relative variation of different stratum cubage unthe within a ball shape with a diameter of 60 meters close to the coal layer to achieve the complete effect of data collection. Further, the data variation rules of the sensor array are easy to identify with a simple data processing and direct abnormality identification.
Description
Technical field
The utility model relates to a kind of natural electric magnetic wave detector, and it can be used for that geologic hazard under the coal mine, tectonic structure are surveyed and the detection of airflight thing etc.
Background technology
At present, utilize the detection mode of natural electric magnetic wave field source that contingent geologic hazard under the coal mine is forecast, in existing document, still do not have report.The signals collecting of prior-warning device generally all is that various sensors are set near mining face under mine under the existing coal mine, analyzes according to the variation of sensor institute image data then, and gives a forecast.The sort signal acquisition mode is cumbersome, not only need be at the mining face under mine sensor installation again of holing earlier, also need simultaneously whether multiple sensors is caused because of rock stratum behind the seam mining is loosening that the variation of sensor installation site observes.For example: " the real-time monitoring and warning device of floor, colliery gushing water " that domestic Xi-an Branch of Coal Science Research Academy hydrology is developed, this device just need bore the boring of different depth at the crossheading of workplace, bury sensors such as stress, strain, water temperature, hydraulic pressure, water chemistry in boring underground, the variation according to sensor institute image data gives a forecast to the base plate gushing water then.The data acquisition of this device is gathered for point, is difficult to comprehensively, and data analysis is more complicated also, and unusual identification is directly perceived inadequately.
The utility model content
The purpose of this utility model is in order to overcome the shortcoming in the prior art, a kind of three-dimensional array type natural electric magnetic wave detector is provided, thereby reach data acquisition comprehensively, directly, data processing is discerned effects such as directly perceived easily, unusually, simultaneously, avoid the down-hole sensor installation because of seam mining after the loosening insecure shortcoming of signal that receives in rock stratum.
For achieving the above object, solution of the present utility model is as follows:
It is made of a spherical carriage and the flat capacitor sensor array that is arranged on this spherical ball bracket crown.
Above-mentioned flat capacitor sensor has two copper-clad plates that size is identical, the copper platinum face of these two copper-clad plates is relative in twos, and between two copper platinum, be provided with one deck insulating material, outside surface two copper-clad plates is provided with a metallic shield, and two copper-clad plates are fixed together by this metallic shield, it also is provided with two signal extension lines, and the copper platinum face of one of them signal extension line and a certain copper-clad plate joins, and another extension line and metallic shield join.
Periphery at above-mentioned spherical carriage is provided with chimb.
On described spherical carriage, be provided with a loam cake, and between described flat capacitor sensor array and loam cake, be provided with foamed material.
By above-mentioned solution as can be seen, the utility model has adopted the flat capacitor sensor array, and this sensor array is arranged on the spherical carriage, because the flat capacitor sensor is a kind of natural electric magnetic wave sensor, simultaneously, present spherical arranged in arrays again, therefore, it can the spherical crown space-oriented or extends to enlarge to the earth and survey, and realizes the three-dimensional detection function.This detection can take remote measurement away from the target that is detected, therefore, can remove the down-hole from installs, simultaneously, it can collect near the interior relative information that changes of Different Strata volume element integrated stress of forward and backward, the upper and lower 60 meters scopes coal seam, reaches the comprehensive effect of data acquisition, moreover, the Changing Pattern ratio of sensor array column data is easier to differentiate, and data processing is simpler, and unusual identification is also directly perceived.

Embodiment
Describe structure of the present utility model and principle of work below with reference to the accompanying drawings in detail.
Referring to Fig. 1,2, it is made of a spherical carriage 1 and the flat capacitor sensor array 2 that is arranged on this spherical ball bracket crown, wherein each flat capacitor sensor by screw retention on described carriage 1.Be convenient on spherical carriage 1, arrange and install in order to make the flat capacitor sensor, periphery at spherical carriage 1 is provided with chimb 1-1, simultaneously, it is stable for sensor is installed, on spherical carriage 1, also be provided with a loam cake 10, and between flat capacitor sensor array 2 and loam cake 10, be provided with foamed material 11 (can be foam fragment or expanded beads).
Referring to Fig. 3, described flat capacitor sensor has two copper-clad plates 3 that size is identical, 4, the substrate of described copper-clad plate is an insulcrete, the one side of substrate is provided with layer of copper platinum, described two copper- clad plates 3,4 copper platinum face 3-1,4-1 is relative in twos, and between two copper platinum faces, be provided with a layer insulating 5, this insulation course can adopt an insulating paper, like this, they have just formed an electric capacity, owing to the distance between two copper platinum faces is very near, (distance between the capacity of flat capacitor device and two plates is inversely proportional to so the electric capacity of this electric capacity is big, distance is more little, capacity is big more, distance is big more, capacity is more little), outside surface two copper-clad plates is provided with a metallic shield 6, by this metallic shield two copper-clad plates are fixed together, this metallic shield 6 forms an electric capacity again with copper platinum face 3-1, but the distance between two plates is bigger, so its electric capacity is less, can be assumed to be zero, so form a potential difference (PD) between above-mentioned two electric capacity, this potential difference (PD) promptly is the signal that sensor received, the signal output part of this sensor joins with the aviation socket by extension line 8 and extension line 9, and by aviation socket and transmission line signal is sent into the early warning and monitoring instrument.When this sensor was surveyed, its test surface 7 was facing to being detected object.
Referring to Fig. 4, when this detector is used under the coal mine geologic hazard and surveys,, and adjust itself and the angle on ground with aboveground (in the control room) of its placement, the centre of its test surface aligning mining face under mine is got final product.When this detector is used for space flight physical prospecting survey, place it on the ground, its test surface subtend is aerial.When this detector was used for tectonic structure and surveys, this detector was placed on the ground, and its test surface is to earthward.According to different detected object, the mode of available circuit frequency-selecting extracts relevant target information.
