Description
Technical field
The invention belongs to the geophysical survey field, particularly relate to a kind of solid pull-type offshore shooting receiving trap.
Technical background
Pull-type offshore shooting receiving trap mainly is by the nautical receiving set in the towing cable, when carrying out offshore shooting, is used for receiving the acoustic reflection signal of ocean Different Strata.Nautical receiving set in the cable changes into electric signal to the acoustic signals that receives, and by signal conductor electric signal is transferred to register instrument again, and register instrument receives, stores and analyzes the electric signal that nautical receiving set transmits, and then learns the information on ocean and stratum, seabed.
At present, the structure of conventional pull-type offshore shooting receiving trap has two kinds:
One, liquid towrope is made up of lead, nautical receiving set, cable bearer, Kev stay cord, towing cable connector and oversheath, and the filling material in the towing cable is a liquid paraffin oil.The shortcoming of liquid towrope is: (1) oversheath is damaged easily, and after the oversheath breakage, liquid paraffin oil can flow to the operation marine site, can cause more serious pollution to the operation marine site.Now a lot of countries have banned use of the liquid towrope to carry out offshore shooting.(2) the liquid paraffin oil in the liquid towrope has corrosivity, can quicken the aging speed of nautical receiving set in the towrope, influences the serviceable life of liquid towrope.(3) when sea situation was relatively more abominable, the environmental noise of liquid towrope was too big, can't continue operation, has influenced operating efficiency.(4) maintenance cost height need be changed whole oversheath during maintenance.
Two, fill the glue towrope, be made up of lead, nautical receiving set, cable bearer, Kev stay cord, towing cable connector and oversheath, the filling material in the towing cable is a gel.The shortcoming of filling the glue towrope is: (1) oversheath is damaged easily, and after the oversheath breakage, after the gel in the towing cable was met water, intensity can reduce greatly, and gel separates with oversheath, greatly reduces the acoustical behavior of towrope.(2) maintenance of filling the glue towrope is very inconvenient, and present technological level when cleaning towrope, can't be fallen the gel place to go completely, causes injecting afterwards new gel in the cable and oversheath in conjunction with not tight, has influenced the sound translative performance of towrope.(3) when sea situation was relatively more abominable, the environmental noise of liquid towrope was too big, can't continue operation, has influenced operating efficiency.(4) maintenance cost height need be changed whole oversheath during maintenance.
Summary of the invention:
The objective of the invention is to solve and overcome above-mentioned the deficiencies in the prior art, a kind of problem that can avoid traditional towrope to pollute the operation marine site easily is provided, when sea situation is relatively more abominable, can continues operation and the cheap pull-type offshore shooting receiving trap of maintenance cost.The present invention is achieved in that
A kind of solid pull-type offshore shooting receiving trap; comprise towing cable acoustics part and two towing cable connectors that are connected to its both sides; the towing cable acoustics of described pull-type offshore shooting receiving trap partly comprises power lead; signal conductor; nautical receiving set and oversheath; power lead is positioned at core; outside it, from inside to outside be disposed with the first tygon protective seam; the Kev stay cord; the second tygon protective seam; described signal conductor is wrapped in the outside of the second tygon protective seam; the 3rd tygon protective seam is set outside described signal conductor; the 3rd tygon protective seam is provided with the rigid foam layer; described nautical receiving set is positioned at a sealed at both ends tubule; one end of tubule is drawn lead; the lead of drawing is connected to described signal conductor; on the rigid foam layer, offer spiral helicine groove; tubule is wrapped on the rigid foam layer along groove, is outside equipped with oversheath at rigid foam layer and tubule.
As preferred implementation, solid pull-type offshore shooting receiving trap of the present invention, the material of rigid foam layer is polyurethane, tygon or polypropylene; Be filled with gel in the tubule; The material of oversheath is a polyurethane.
The invention has the advantages that:
(1) environmental protection does not have liquid in the cable, can not pollute the operation marine site.
(2) intensity of cable is big, and oversheath is cracky not.
(3) operating efficiency height, low to the sea situation requirement, compare under the condition of severe in sea situation, still can continue operation.
(4) filling material in the cable does not have corrosivity, the long service life of cable.
(5) maintenance cost is low, during maintenance, only need get final product the breakage reparation, need not change whole oversheath.

Fig. 1, overall schematic of the present invention.
Fig. 2, towing cable acoustics fragmentary cross-sectional view of the present invention.
Fig. 3 towing cable acoustics of the present invention part nautical receiving set tubule distribution schematic diagram.
Embodiment:
The present invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention partly is made up of towing cable connector and towing cable acoustics.The towing cable connector is positioned at the two ends of towing cable, is used for the connection between the towing cable or is used for towing cable and being connected of miscellaneous part.
As shown in Figure 2, the present invention is made up of power lead 1, tygon protective seam 2, Kev stay cord 3, tygon protective seam 4, signal conductor layer 5, tygon protective seam 6, rigid foam layer 7, oversheath 8 and nautical receiving set tubule 9.Core of the present invention is a power lead, the first, at first make power lead 1, after carrying out, at its outside plating layer of polyethylene protective seam 2.The second, at tygon protective seam 2 outsides braiding one deck Kev stay cord 3, again at Kev stay cord 3 outsides plating layer of polyethylene protective seam 4.The 3rd, twine one deck signal conductor layer 5 in tygon protective seam 4 outsides, then at signal conductor layer 5 outside plating layer of polyethylene protective seam 6.The 4th at tygon protective seam 6 outsides plating one deck rigid foam 7, processes spiral groove then on rigid foam 7.The 5th, nautical receiving set to be packed in the polyurethane tubule, gel filled, sealed at both ends in the pipe, wherein an end is drawn lead.The 6th, nautical receiving set tubule 9 is wrapped in the spiral groove, the lead that tubule one end is drawn is connected with signal conductor layer 5, and is last, at rigid foam layer 7 outside plating one deck polyurethane oversheath 8.Nautical receiving set tubule 9 and oversheath 8 are combined closely, and have filled gel in the nautical receiving set tubule 9, make nautical receiving set can well receive extraneous acoustic signals, have guaranteed the acoustical behavior of towing cable acoustics part.
The nautical receiving set that constitutes one section towing cable acoustics part can be many groups, and present embodiment is 12 groups, and every group is composed in parallel by a plurality of nautical receiving sets, and each nautical receiving set all is contained in the tubule.
