Abstract
The utility model provides a three-component geophone placement device which comprises a regular pentagonal prism joint nut, a horizon indicator and five telescopic rods. The middle part of each side face of the regular pentagonal prism joint nut is formed with a screw hole. The horizon indicator is installed at the center of a top face of the regular pentagonal prism joint nut. Each of the telescopic rods is formed by the connection of a large-diameter stainless steel pipe, a middle-diameter stainless steel pipe and a small-diameter stainless steel pipe in an embeddable way. The outer end of the large-diameter stainless steel pipe of each telescopic rod is connected with a joint screw, and the telescopic rod is connected to a screw hole at one side face of the regular pentagonal prism joint nut by using the joint screw. The three-component geophone placement device can rapidly and accurately determine an embedded position of a three-component geophone in micro detection, thus the accuracy and efficiency of data collection in the field can be raised, and the device is especially suitable for a city green belt and a field occasion with sparse bushes and the like. In addition, the placement device has the advantages of reasonable and simple structural design and low cost and is convenient to store, carry and use.
Description
Technical field
The invention belongs to the geophysical exploration technology field, particularly relate to a kind of three-component seismometer placing device.
Background technology
At the earth's surface, no matter when and where all there are a kind of natural faint vibrations, are referred to as " fine motion ".The focus of fine motion mainly comes from spontaneous phenomenon and mankind's activity, the former is changed by weather, air pressure and wave, morning and evening tides etc. to produce, frequency is less than 1Hz, the latter then be by vehicle travel, generation such as machine and human daily life, activity in production, frequency is greater than 1Hz.
Fine motion is a kind of complex vibration of being made up of bulk wave (P ripple and S ripple) and ground roll (R wave and Love wave), and the energy of ground roll accounts for more than 70% of signal gross energy.Although the amplitude of fine motion signal and form be space-variantization and changing at any time, in certain space-time unique, have statistics stability, so the stationary stochastic process on pot life and the space is described.The fine motion detection method is foundation with the stationary stochastic process theory exactly, extracts the dispersion curve of ground roll (R wave) from the fine motion signal, by the inverting to dispersion curve, obtains the shear wave velocity structure of underground medium.
At present, the fine motion detection data generally adopts circular array fine motion recording geometry to gather.Fig. 1 is a kind of circular array fine motion recording geometry synoptic diagram commonly used.As shown in Figure 1, this system is made of a plurality of circular array, and each circular array is made up of 6 pendulum and the data acquisition system (DAS) that are embedded in this circle inscribe pentagon summit and central point below, puts and data acquisition system (DAS) adopts three-component seismometer usually.The pentagon summit is called the observation radius R to the distance of central point.But, there is following point in the circular array fine motion recording geometry of this prior art: when the three-component seismometer that is positioned at place, pentagon summit is positioned at the urban afforestation band just or has sparse bushes etc. field condition, distance between this place and the central point just is difficult to accurate measurement, therefore this position also is difficult to determine, will cause measurement result accuracy poor like this, and inefficiency.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of three-component seismometer placing device that can improve field data collection accuracy and work efficiency.
In order to achieve the above object, three-component seismometer placing device provided by the invention comprises positive pentagonal prism collar nut, level indicator and five expansion links; Wherein each middle part, side of positive pentagonal prism collar nut is formed with a screw; Level indicator is installed in the end face center of positive pentagonal prism collar nut; Expansion link is linked together in nestable mode by big footpath, middle footpath and three stainless-steel tubes of path and constitutes, stainless-steel tube outer end, big footpath on every expansion link is connected with a connector screw, and utilizes connector screw to be connected in the screw on the side of positive pentagonal prism collar nut.
When described expansion link all launched, path stainless-steel tube outer end to distance between the positive pentagonal prism collar nut axial centre equaled to observe radius R on it.
Junction between described big footpath and middle footpath stainless-steel tube and middle footpath and the path stainless-steel tube is provided with register pin.
Three-component seismometer placing device provided by the invention can be determined the embedding position of three-component seismometer rapidly and exactly when fine motion is surveyed, therefore can improve accuracy and the work efficiency of field data collection, be specially adapted to the urban afforestation band and have sparse bushes etc. field condition.In addition, this placing device also has reasonable in design, simple, is convenient to deposit, carries and use, low cost and other advantages.

Fig. 2 is three-component seismometer placing device structural representation provided by the invention.
Fig. 3 is expansion link structural representation in the three-component seismometer placing device provided by the invention.
Embodiment
Below in conjunction with the drawings and specific embodiments three-component seismometer placing device provided by the invention is elaborated.
As Fig. 2, shown in Figure 3, three-component seismometer placing device provided by the invention comprises positive pentagonal prism collar nut 1, level indicator 2 and five expansion links 3; Wherein each middle part, side of positive pentagonal prism collar nut 1 is formed with a screw; Level indicator 2 is installed in the end face center of positive pentagonal prism collar nut 1; Expansion link 3 is linked together in nestable mode by big footpath, middle footpath and three stainless-steel tubes of path and constitutes, stainless-steel tube outer end, big footpath on every expansion link 3 is connected with a connector screw 4, and utilizes connector screw 4 to be connected in the screw on the side of positive pentagonal prism collar nut 1.
When described expansion link 3 all launched, path stainless-steel tube outer end to distance between positive pentagonal prism collar nut 1 axial centre equaled to observe radius R on it.
Junction between described big footpath and middle footpath stainless-steel tube and middle footpath and the path stainless-steel tube is provided with register pin 5.
Now three-component seismometer placing device using method provided by the invention is described below: when not needing to use this placing device, expansion link 3 can be disassembled from positive pentagonal prism collar nut 1, simultaneously middle footpath and path stainless-steel tube are pushed in the stainless-steel tube of big footpath, be convenient to like this deposit and carry.On-the-spot when needing to use this placing device that three-component seismometer is set when in the open air, at first by the staff all expansion links 3 all are tightened in five screws on the positive pentagonal prism collar nut 1, then the bottom center of positive pentagonal prism collar nut 1 is placed on the central spot of a circular array, afterwards middle footpath and path stainless-steel tube are all extracted out in the stainless-steel tube of big footpath, junction between big footpath and middle footpath stainless-steel tube and middle footpath and path stainless-steel tube installs register pin 5 then, regulate the level of each expansion link 3 afterwards by means of level indicator 2, all be in horizontality up to all expansion links 3, at this moment, the position at place, path stainless-steel tube outer end is the embedding place of three-component seismometer.
