With consideration of leak tightness of the submarine towing cable and protection for the internal structure, an outer waterproof bushing is added outside of the reinforcing rope. A cable fixing glue layer is added outside of the cable. The water transmission pipe is made of Nylon 11 material, and the reinforcing rope is braided with Kevlar material. The present invention integrates water transmission, power transmission, and towing function to produce a towing cable that is different to steel wire cables or conventional armored cables. That is to say, the present invention provides a shipboard expendable continuous sampling system, particularly a towing cable that can be used to take water samples in real time, especially a towing cable that is loaded on a towing platform for a continuous water sampling system, with a water transmission pipe and conduction and signal transmission capability, and high tensile strength, designed to accomplish shipboard expendable continuous water sampling tasks at different predefined depths or implement shipboard expendable, quick, and online water quality monitoring.
Description
Technical field
The present invention relates to a kind of possess water delivery, conduction, dilatory multifunctional underwater towing line.
Background technology
Present common towing cable has two kinds on intensity wire hawser and armouring cable.Wire hawser is generally used in littoral superficial sea area.Such wire hawser is convenient to the operation on the deck, and its load-bearing capacity depends on the inner size that strengthens core.Armoured cable is used for darker sea area.General armoured cable has the metallic sheath of two-layer opposite direction spiral coiled.Armour can watertight, and also watertight is not decided by the material of armouring.No matter whether armour watertight, cable must have insulating barrier protection.
Marine environmental monitoring is the basis of scientific research of seas, resources development and utilization and environmental protection and management.Problem of environmental pollution is serious day by day at present, the emphasis that the on-the-spot fast monitored of ocean water quality and biological environment parameter and analytical technology become research.At present, water pollution on-the-spot on-line monitoring technique in ocean mainly contains two developing direction, and one is the chemical sensor method, and another is " underwater miniature laboratory " method.Chemical sensor can be realized fast, in situ detection, but chemical sensor insufficient sensitivity height, test item is less." underwater miniature laboratory " method is to develop technique direction faster.This method is extracted into seawater under water and measures in the instrument, has realized on-the-spot on-line monitoring.But there is the cost height again in " sealab method ", and precision is low, technology realizes problems such as difficulty.
As water sampling system being carried under water on the tow platform, follow tow platform and carry out wave and depthkeeping motion, be the feasible solution of finishing the boating type continuous acquisition water sample of different desired depths.But underwater towing line commonly used only possesses dilatory and conducting function, does not possess the water delivery function, becomes the bottleneck problem of Sampling techniques.
Though the BURKE HALES of Oregon, America university has designed a kind of towing cable that is applied to drawing sampling.But because the most depth of water of CHINESE OFFSHORE is more shallow, towing system needs can be rapid, frequent rise and fall, so the stressed pace of change of towing system is very fast.And HALES design adopt the water towing cable, strengthen cable directly contact with cable, when stressed variations of towing system, the displacement friction can appear in reinforcement cable and cable, meeting generation potential safety hazard after the use long period; Simultaneously, the outer watertight composition that twines must have certain winding pressure to middle other cable layers for reaching the watertight requirement.Therefore it is inhomogeneous to make the reinforcement cable bear pulling force, influences towing cable and bears ability.
Summary of the invention
The purpose of this invention is to provide a kind of possess water delivery, conduction, dilatory multifunctional underwater towing line, adopt the deficiency of using in the water towing system under water continuously with what overcome above-mentioned prior art, on the basis that guarantees the electric property that sufficient intensity is become reconciled, a kind of continuous towing cable of water sampling system under water is provided, particularly carries the towing cable that a kind of that continuous water sampling system on tow platform uses includes water-supply-pipe, has conduction and transmission signals ability, tensile strength is high.
The present invention is the improvement to existing towing cable, specifically is achieved in that to the invention is characterized in from the center to skin and be water-supply-pipe successively, be used to power and cable and the water string and the reinforcement cable of data communication.
Consider the sealing of towing cable and to the protection of internal structure, water string outside above-mentioned reinforcement cable outside is provided with again.
Consider to overcome the problem of sliding in cable and water-supply-pipe mutual alignment, cover outside above-mentioned cable that the fixed cable of one deck uses gelatinous layer---cable is gelatinous layer fixedly.
The present invention is integrated with water delivery, conductivity and dilatory function, makes the towrope that is different from wire hawser or traditional armouring cable.Towing cable main difference than the BURKE HALES of Oregon, America university design is:
1. outside cable floor, increase fixedly gelatinous layer of cable, make towing cable inside conductor arrangement position fix, solved in the towing cable use problem of sliding in cable and water-supply-pipe position.
2. adopt water string to replace original nylon watertight composition.
3. strengthen cable outside the water string layer, reduced and strengthened the wearing and tearing of cable to cable, the reliability and the useful life of having improved towing cable in the towing process; Strengthen cable outside watertight composition, be not subjected to the nylon watertight composition to twine the influence of frictional force, it is more even that the reinforcement cable bears pulling force, improved the bear ability of cable under identical material and size of strengthening.

Embodiment
As Fig. 1, basic structure of the present invention is to outer being followed successively by water-supply-pipe 1, being used to power and the cable 2 and the water string 3 of data communication and strengthen cable 4 from the center.
As Fig. 2, as another embodiment, also as the effect of insulating barrier, again strengthen cable 4 outsides be provided with outside water string 5.Be that the towing cable outermost layer is again a wear-resisting water string---outer water string 5.Outer water string 5 is identical with water string 3 materials.
As Fig. 3, consider the problem of sliding in cable 2 and water-supply-pipe 1 position, at the fixing gelatinous layer 6 of the outer cabling of cable 2, make 24 interior copper conductor arrangement positions of cable fix.The i.e. cable of forming at evenly distributed 24 copper conductors of water-supply-pipe 1 periphery 2; Above-mentioned cable 2 is outer cover the fixed cable of one deck gelatinous layer---cable is gelatinous layer 6 fixedly, it is wear-resisting water string 3 outward; Water string 3 outsides are the reinforcement cables 4 of being worked out by aramid fiber.
Water-supply-pipe 1 is selected the nylon 11 material specially for use, the nylon 11 material is that physics and chemical property are the most stable, the also good nylon material of wear-resistant, bendability, and nylon 11 smooth surface, can prevent to get rusty, fouling, resistance to chemical attack, long service life, nylon 11 resistance greatly can use as insulator again.
