Background technology
In general, marine seismic prospectiong explores ship progress by sea going, after the seismic origin and water channel are located at ship
The water channel in face, while seismic wave is sent into submarine structural, the seismic wave of reflection is collected and analyzes, so as to measure geology knot
Structure.
In the 3-d seismic exploration using very big ships such as petroleum exploration ships, ship at sea moves, and one
As have two or more rows push towing cable, every extend several kilometers or longer, therefore, though when towing cable in case of wet when due to them
Anxiety, they can check their linear and relative position by several GPS.
However, in the case of the 3D seismic prospectings using spitkit, if using about 10 meters but not being relatively long
The relatively short towing cable of about 100 meters of towing cable gather 3D survey datas, then towing pennant does not almost have tension force, so, if
In trend, they can not be maintained at normal relative position.
Utility model content
The purpose of this utility model is just to provide one kind that spitkit can be used to carry out seismic prospecting with towed
The ship of seismic survey devices.
Technical solution of the present utility model is：
A kind of ship with towed seismic survey devices, including it is ship body, the first towing cable, earthquake source device, preceding
Support bar, the second towing cable, back support rod, hydrophone, GPS device, connecting rod, flaps, it is characterised in that：In ship body
Rear end is connected with earthquake source device by the first towing cable, the rear end of the first towing cable is provided with front support rod, in front support rod
Rear end is provided with back support rod by the second relative towing cable of left and right, several hydrophones is laid with the second towing cable, preceding
Support bar, the left and right ends of back support rod are separately installed with four GPS devices, are installed in the rear end of back support rod by connecting rod
There is flaps.
Further, the earthquake source device is air gun.
Further, the front support rod, back support rod are made by buoyant material, front support rod, back support rod by
Several first support bars, which are connected through a screw thread, to be formed, and the inside being bonded with each other is respectively arranged with the left and right ends of first support bar
Screw thread and external screw-thread, the middle part of first support bar is provided with connection holes, interior spiral shell is provided with the inwall of connection holes
Line.
Further, there is the external screw thread that is complemented one another with internal thread in the end set of the second described towing cable.
The beneficial effects of the utility model are：It is simple in construction, easy to use, obtained using ship on subsurface geologic structures
Marine seismic prospectiong data.

Embodiment
Structure of the present utility model and operation principle are described in further details below in conjunction with the accompanying drawings.
According to Fig. 1-Fig. 3：A kind of ship with towed seismic survey devices of the utility model, including ship sheet
Body 1, the first towing cable 2, earthquake source device 3, front support rod 4, the second towing cable 5, back support rod 6, hydrophone 7, GPS device 8, connection
Bar 9, flaps 10, it is characterised in that：Earthquake source device 3 is connected with by the first towing cable 2 in the rear end of ship body 1,
The rear end of one towing cable 2 is provided with front support rod 4, after in the rear end of front support rod 4, the second towing cable 5 relative by left and right is provided with
Support bar 6, several hydrophones 7 are laid with the second towing cable 5, distinguished in the left and right ends of front support rod 4, back support rod 6
Four GPS devices 8 are installed, flaps 10 is provided with by connecting rod 9 in the rear end of back support rod 6.
The earthquake source device 3 is air gun.
The front support rod 4, back support rod 6 are made by buoyant material, and front support rod 4, back support rod 6 are by several
One support bar 11, which is connected through a screw thread, to be formed, and the inside spiral shell being bonded with each other is respectively arranged with the left and right ends of first support bar 11
Line 12 and external screw-thread 13, the middle part of first support bar 11 is provided with connection holes 14, set on the inwall of connection holes 14
It is equipped with internal thread.
There is the external screw thread to be complemented one another with internal thread in the end set of the second described towing cable 5.
Embodiment：First support bar, one of them first support bar with external screw-thread is screwed to the first adjacent support
