Abstract
The utility model relates to an underwater earthquake wave detector, which is provided with an outer shell, wave detector cores, and a cable lead-through. The lower side of the base of the outer shell is provided with a tail cone; a plurality of wave detector cores are fixed in the outer shell through an upper fixing frame and a lower fixing frame; two O-shaped sealing rings are arranged between the upper cover and the base of the outer shell; the upper part of the upper cover is provided with a cable lead-through hole which is sealed and fixed by a sealing pad and a wire plug. The utility model has the advantages of good waterproof performance, reasonable structure, small size, light weight, convenient embedment, convenient installation, disassembly, and maintenance, and repeatable use, which is suitable for conventional earthquake exploration in water net areas, shallow sea beaches, and swampy lakes.
Description
The utility model relates to a kind of detection instrument, specifically a kind of underwater seismic detector.
As everyone knows, seismoreceiver is widely used in the oil field seismic prospecting, be suitable for carrying out the seismoreceiver or the string of seismic prospecting at present under water, S2-3 type seismoreceiver as the production of Xi'an petroleum exploration instrument factory, the self-designed rubber seal of many employings seals assembling, being connected into string with cable then uses, this wave detector sealing part is many, adopt profiled seal spare, difficulty of processing is big, quality is difficult for guaranteeing, therefore, in assembling process, need additional other encapsulant can be guaranteed, from and caused installation, the very big inconvenience of dismounting and maintenance.
The purpose of this utility model is exactly that existing underwater seismic detector sealing part is many, the deficiency of poor performance in order to overcome, provide a kind of rational in infrastructure, adopt integral sealing, good seal performance, quality height, installation, dismounting, easy to maintenance, the underwater seismic detector that repeat performance is good.
For achieving the above object, a kind of underwater seismic detector, it is provided with shell, detector core body, cable tail, be provided with a tail cone below the base of shell, it is characterized in that some detector core bodies install and fix in the enclosure by upper holder and lower fixed frame, be provided with two " 0 " shape O-ring seals between the loam cake of shell and the base, loam cake top is provided with the cable tail hole, and by sealing gasket and plug sealing and fixing.
The quantity of the detector core body in the utility model shell can be according to oil field user's actual needs setting with mutual the connection, can select 9 detector core bodies for use, adopt three strings three and connection, also can use 12, adopt three strings four and connection, sealing is by the sealing respectively in past, change integral sealing into, reduced sealing part, sealing improves than before greatly, and without the auxiliary seal material, installation, dismounting, easy to maintenance, can reuse, be useful in dense waterway net region, beach, shallow sea, the swampy lake and carry out seismic exploration routinely.
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the utility model structural representation.
As can be seen from Figure 1, a kind of underwater seismic detector, it is provided with closure, detector core body 3, cable tail 4 etc., and shell is made up of loam cake 1 and base 2, and they can be processed by the ABS engineering plastics.Wherein loam cake 1 top is provided with a cable tail hole, and cable tail 4 is drawn from here, and is provided with a sealing gasket 5, by plug 6 screwing hermetics.Base 2 lower ends are connected and fixed a tail cone 7, and it is fixing to be used for assigning of whole wave detector.Be provided with two " e " shape O-ring seals 8,9 between the utility model loam cake 1 and the base 2, O-ring seal 8 is positioned at the groove between loam cake 1 and base 2 end faces, and O-ring seal 9 is arranged in loam cake 1 and base 2 end plays, and O-ring seal 8,9 can adopt standard component, and quality easily guarantees.After two " 0 " shape O-ring seals place, be connected with 8 bolts between loam cake and base, solid and reliable, easily adorn readily removable.
In the utility model shell, be provided with several detector core bodies 3, they are fixed on the base 2 of shell by upper holder 10 and lower fixed frame 11, the quantity of detector core body and connected mode can be explored needs according to reality and be determined, generally can select 12 detector core bodies for use, adopt three string four and connected modes, drawn from the cable tail hole of loam cake 1 by cable tail 4 at last, signal flows to signal receiving device by cable after wave detector picks up.
The utility model water resistance is good, and rational in infrastructure, and volume is little, and is in light weight, Embedding convenience, installation, dismounting, easy to maintenance, reusable, be suitable in the network of rivers Carry out the common seismic exploration in area, beach, shallow sea, the swampy lake.
