Background technology
In traditional field earthquake data acquisition, for ensureing to obtain the high geological data of signal to noise ratio (S/N ratio), wave detector need be inserted underground, received by epicenter excitation signal, carry out seismic prospecting at hard surface, wave detector need be utilized gypsum etc. to be bonded on the table of road, receive on seismic cable afterwards.Such benefit to make wave detector measured and the ground coupling to the greatest extent, can effectively receive the seismic signal propagated by underground medium, reduce extraneous interference.
In traditional working method, the plug trouble very of wave detector, and also after once gathering, all wave detectors and seismic cable section need be opened, and progressively move forward, work efficiency is extremely low.And this working method is suitable for the earth's surface of soil property earth's surface or non-hardened, if the point according to 20m is apart from gathering, adopt 12 roads to receive, track pitch is that the recording geometry of 2m gathers, the rolling of each survey line needs mobile 10 wave detectors, and acquisition speed is slower.Adhesive type wave detector can effectively gather after needing to wait for the medium consolidations such as gypsum, and efficiency is lower, and therefore, the improvement and bring new ideas of detector device is the problem needing solution at present badly.
Summary of the invention
For above-mentioned situation, be solve the defect of prior art, the object of the utility model is just to provide a kind of land pull-type seismic detection cable machinery, effectively can solve the problem that prior art plug trouble, inefficiency, acquisition speed are slow.
The technical scheme that the utility model solves is, comprise steel plate, seismoreceiver, cable and " U " shape ring, 3 U-loops are that isosceles triangle distribution is inserted on steel plate, all fix through nut, spring compressing tablet is provided with between nut and steel plate, seismoreceiver is fixed on steel plate center, multiple seismoreceivers on multiple steel plate all link together through electric wire and cable, link together through steel wire web member between U-loop on every two steel plates, be interconnected between steel wire web member, form Y shape syndeton.
The utility model efficiently solves tradition plug or pastes the lower working method of the work efficiencies such as wave detector, and can useful effect in hard surface, practical application proves, this equipment is while maintenance data acquisition quality, significantly improve the work efficiency of seismic prospecting, is the innovation on detector device.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model.
Fig. 2 is structure vertical view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Provided by Fig. 1-2, the utility model comprises steel plate, seismoreceiver, cable and U-loop, in isosceles triangle, distribution is inserted on steel plate 13 U-loops 3, all fix through nut 10, spring compressing tablet 4 is provided with between nut 10 and steel plate 1, seismoreceiver 2 is fixed on steel plate 1 center, multiple seismoreceivers 2 on multiple steel plate 1 all link together through electric wire 8 and cable 9, link together through steel wire web member 5,6,7 between U-loop 3 on every two steel plates 1, be interconnected between steel wire web member 5,6,7, form Y shape syndeton.
In order to ensure result of use, described steel plate 1 is rectangle.
Described cable 9 is 30 core cables.
Distance between every two of described multiple wave detectors 2 is 2m, described is multiplely at least 3.
Service condition of the present utility model is, point contact type ground connection U-loop is connected with steel plate by nut etc., and between nut and steel plate, utilize spring compressing tablet to fix, structure is fixed solid, without concussion relatively, make between point contact type ground connection U-loop and steel plate, to form one and intend rigid body structure, the U-loop of point contact type ground connection effectively can ensure that pull-type seismoreceiver is coupled with hardened ground well, intending rigid body structure then can the fidelity of effective holding signal, prevent the interference because of inside concussion from forming aftershock thus interference acquisition data, aluminium alloy version is due to the factor such as gravity of self, effectively can apply pressure to point contact type U-loop, make itself and the ground coupling good.The Vibration Condition that wave detector 2 is different according to ground, vibration information is converted into different voltage, and utilizing electric wire 8 to export, the electric signal that electric wire 8 exports is divided into ﹢ voltage and ﹣ voltage two kinds, and+pressure-wire and ﹣ pressure-wire are connected in instrument this electrical signal collection to get off by cable 9.Acquisition mode due to whole cable needs mobile, for keeping the balance of movement, utilizing steel wire web member 5,6,7 as stressed member, can effectively carry out moving and effectively protecting cable by towed hydrophone like this.Utilize 5,6,7 triangular patterns formed carry out connecting and pull advance between each U-loop 3, the distance between two wave detectors needs to regulate according to real work, generally remains on 2m.Multiple wave detector 2 is all connected in cable 9 through electric wire 8, and cable 9 is 30 core cables, effectively can connect 15 wave detectors.According to the condition of acceptance of instrument, every bar detection cable connects 12 wave detectors.Wave detector adopts bikini earthing mode, seismoreceiver and ground can be made to reach optimum coupling, avoiding producing oscillator signal because not being coupled, affecting image data.Utilize spring compressing tablet to make point contact type ground connection equip with steel plate in intending rigid body structure, intending rigid body structure then can the fidelity of effective holding signal, prevents the interference formation aftershock of shaking because of inside thus interference acquisition data.The application of point contact type earthing mode, can break away from the larger earthing mode of other area and the poor problem of the ground coupling.
The utility model can utilize the means of transports such as automobile to tow on ground, avoids traditional drawback plugging wave detector back and forth.Can significantly increase work efficiency.Multiple wave detector can be connected to automobile tail, and be placed on automobile by signals collecting instrument after connecting, complete any excite with signals collecting after, automobile can be utilized to be dragged to next measuring point and to carry out signals collecting.
The utility model land pull-type seismic acquisition and traditional seismic acquisition contrast, the seismologic record gathered due to traditional seismic acquisition is reliable, for the reliability of checking land pull-type seismic cable collection effect, two kinds of cables are placed on instrument and carry out contrast test.In test, the wave detector of 12 road pull-type seismic cables is corresponding one by one with the wave detector of 12 land, road plug-in seismic cables, track pitch adopts 2m, and shot interval adopts 10m.Adopt 24 road seismic receiver, sampling interval is 0.1ms, and sampling number is 4096.For getting rid of the different impacts excited producing, reception land, the 1-12 road pull-type seismic cable signal of geological data, the 13-24 road of geological data receives the seismic signal of traditional plug-in wave detector reception.The data that both contrasts gather, because concrete road surface signal attenuation is slow, so the direct-path signal of the just land pull-type seismic cable collection of concrete road surface layout is better than traditional plug-in seismic cable.The two ground roll signal phase gathered is consistent, and signal characteristic coincide good.
By contrast test, prove that the utility model pull-type seismic detection cable machinery meets the demand of production work in design completely.Compared to traditional plug-in seismic cable, pull-type seismic cable can utilize the vehicles such as automobile to pull, therefore work efficiency is high, relatively traditional seismic acquisition, work efficiency can promote more than 3 times, while maintenance data acquisition quality, significantly improves the work efficiency of seismic prospecting, be the innovation on detector device, there is good economic and social benefit.
