Problems solved by technology

However, since most of China's coastal waters are relatively shallow, the towing system needs to be able to rise and fall quickly and frequently, so the force of the towing system changes quickly
In the water harvesting tow cable designed by HALES, the reinforcement cable is in direct contact with the cable. When the force of the towing system changes, displacement friction will occur between the reinforcement cable and the cable, which will cause safety hazards after a long period of use; at the same time, the outer layer is wound waterproof In order to meet the watertight requirements, the layer must have a certain winding pressure on the other cable layers in the middle.
Therefore, the reinforcement cable will bear uneven tension and affect the pulling capacity of the tow cable

Embodiment 1

[0025] Such as image 3 , The water delivery pipe 1 adopts a nylon 11 pipe with an outer diameter of 10mm and a wall thickness of 1.5mm. Its compressive strength is 1.9Mpa, breaking strength is 5.7Mpa, and the minimum bending radius is 60mm.

[0026] The cable 2 is composed of 24 insulated copper wires evenly arranged around the water pipe 1 . Each wire is Φ0.16mm×11, the rated current is 2A, and the breakdown voltage between the wires is 500V. Among them, fifteen wires are selected, each group of five wires, a total of three groups, are used for single-phase three-wire AC power supply; the remaining wires are used to transmit the power supply and data communication of the towed platform sensor and the towed system control electrical. Wherein the cable fixing gel layer 6 is used to solve the problem that the position of the cable 2 and the water delivery pipe 1 slides, so that the arrangement position of the cables in the tow cable is fixed.

Abstract

The present invention relates to a multi-functional submarine towing cable, which is characterized in: the towing cable comprises from center to exterior as follows: water transmission pipe, cables for power supply and data communication, waterproof bushing, and reinforcing rope. With consideration of leak tightness of the submarine towing cable and protection for the internal structure, an outerwaterproof 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 [0001] The invention relates to a multi-functional underwater tow cable with the functions of water delivery, conduction and dragging. Background technique [0002] At present, there are two kinds of common tow cables: strength steel wire cable and armored cable. In the relatively shallow sea area along the coast, steel wire cables are generally used. This type of wire rope is easy to handle on deck, and its load capacity depends on the size of the internal reinforcing core. Armored cables are used in deeper sea areas. Generally armored cables have two metal sheaths helically wound in opposite directions. The armor layer can be watertight or not, depending on the material of the armor. Whether or not the armor is watertight, the cable must be protected by an insulating layer. [0003] Marine environmental monitoring is the basis of marine scientific research, resource development and utilization, and environmental protection and management. At present, ...
