The invention belongs to field of geophysical exploration, relate to a kind of pull-type damping cable for marine seismic prospectiong, comprise and couple together leading cable with connector successively, damping section, active section, damping section, tail rope, the several part of buoy, vibration damping section wherein, comprise sheath, be positioned at vibration damping rope and the wire of sheath, the middle part of vibration damping section is provided with fixed support, for fixing shock cord and support sleeve, on support bracket fastened both sides, also be respectively arranged with conversion support, for conversion and the support sleeve of shock cord, described vibration damping rope is made up of the nylon rope of some band braided sheath, shock cord is divided into three sections, the two ends being positioned at a middle strand damping rope are separately fixed on conversion support, be positioned at the two strand damping ropes on both sides, one end of every strand damping rope is fixed on conversion support, and the other end is fixing on the connectors.The present invention has good damping effect, lightweight, pollution-free, good environmental adaptability, use advantage that is reliable, that easily safeguard.
Description
Technical field
The invention belongs to field of geophysical exploration, particularly relate to a kind of pull-type cable.
Background technology
Pull-type cable for marine seismic prospectiong can be divided into leading cable → front damping section → active section → tail damping section → several part of tail rope → buoy, at present, front damping section and tail damping section are distributed in former and later two parts of solid cable respectively, are all the vibration interference that when utilizing shock cord to reduce towing work, geophysical vessel and tail tag bring to the active section of towing cable usually.Shortcoming is:
1, shock cord is the nylon rope of single band establishment sheath, and the percentage elongation of this nylon rope is low, and damping effect is poor.
2, jacket thickness is generally greater than 3.3 millimeters, weight ratio is heavier.
Summary of the invention
The object of the invention is solution and overcome above-mentioned the deficiencies in the prior art, provide a kind of good damping effect of damping section and the lightweight pull-type damping cable for marine seismic prospectiong.The present invention is achieved in that
A kind of pull-type damping cable for marine seismic prospectiong, comprise and couple together leading cable with connector successively, damping section, active section, damping section, tail rope, the several part of buoy, damping section wherein, comprise sheath, be positioned at shock cord and the wire of sheath, the middle part of damping section is provided with fixed support, for fixing shock cord and support sleeve, it is characterized in that, described damping section, on support bracket fastened both sides, also be respectively arranged with conversion support, for conversion and the support sleeve of shock cord, described shock cord is made up of the nylon rope of some band braided sheath, shock cord is divided into three sections, the two ends being positioned at one section of middle shock cord are separately fixed on conversion support, be positioned at two sections of shock cords on both sides, one end of every section of shock cord is fixed on conversion support, and the other end is fixing on the connectors.
Preferably, in sheath, light wax oil is filled with.The invention has the advantages that:
1, shock cord segmentation composition, and for there being sth. made by twisting, namely have employed many nylon ropes, like this, improve elasticity and reliability, good damping effect, improve 6 decibels than the damping performance of conventional damping device.
2, lightweight, owing to improving the structure of damping section, the thickness of the sheath of employing can reduce.
3, light wax oil has stronger mobility, and when cable is by ambient pressure, light wax oil flows thus balanced cable internal pressure, plays the effect of each support of protection, prevents support crushed.
Accompanying drawing explanation
Fig. 1, structural representation of the present invention.
Accompanying drawing is described as follows: 1, connector 12, sheath 3, the 1st section of shock cord 4, conversion support 15, the 2nd section of shock cord 6, fixed support 7 wire 8, conversion support 29, light wax oil 10, the 3rd section of shock cord 11, connector 2
Embodiment:
Below in conjunction with drawings and Examples, the present invention will be further described.
As shown in Figure 1, the present invention is made up of connector 1, sheath 2, the 1st section of shock cord 3, conversion support 4, the 2nd section of shock cord 5, fixed support 6, wire 7, light wax oil 8 and the 3rd section of shock cord 9.Connector is positioned at the two ends of device, for the connection between damping device or the connection for damping device and miscellaneous part.Every section of shock cord is made up of the nylon rope of 3 band braided sheath.
The first, one end of the 1st section of shock cord is connected with connector 1, the other end of the 1st section of shock cord is connected with conversion support 1.
The second, one end of the 2nd section of shock cord is connected with conversion support 1, the other end is through being connected with conversion support 2 after fixed support 6.
3rd, one end of the 3rd section of shock cord is connected with conversion support 2, the other end is connected with connector 2.
4th, one end of wire is connected with connector 1, the other end is connected with connector 2 through after conversion support 1, ordinary stent and conversion support 2.
5th, the above-mentioned part connected is loaded in sheath.
6th, the two ends of sheath and connector 1, connector 2 steel loop crimping are sealed.Filling full light wax oil in sheath.
