Description

Multi-use mode underwater cable penetrating device

Technical Field

The utility model relates to a cable device technical field, concretely relates to cable device is worn under water to many usage patterns.

Background

The threading of the rope is a key step for salvaging sunken ships or small-sized sunken objects, and directly relates to the success or failure of salvaging operation. Generally, underwater cabling is carried out in a water area which is less than 80 meters, by means of divers, and underwater cabling is carried out in a water area which is less than 80 meters, and mainly by means of ROVs (remote operated vehicles).

When the underwater cable penetrating operation is carried out by a diver, once the cable needs to be penetrated in the internal structure of the ship or the cable is covered in a small-sized sediment with deeper mud, the operation by hands of the diver is very difficult, and the reason is that: the ship internal structure is far away from the diver and the space is narrow, arms are difficult to go deep or go deep enough, and the existence of sludge makes cable penetrating laborious. When the cable threading operation is carried out by means of the remote-control submersible, the two manipulators act cooperatively, so that the operation difficulty is high, and the cable threading success rate is low.

The applicant discloses a diver's handheld cable device of wearing under water (hereinafter referred to as "primary product") at the utility model patent CN202122722881.6 of 2021 month 09 application, relates to dive salvage technical field, including the clamp body, the clamp body include first centre gripping arm and second centre gripping arm, the work end of first centre gripping arm fixedly be equipped with wear to draw the piece, the work end joint of second centre gripping arm have the cable guide, the cable guide on be fixed with the end of jack cable, wear to draw the piece and cooperate mutually with the cable guide, and the structure of wearing to draw the piece is satisfied: the cable guiding piece can be unlocked from the working end of the second clamping arm, and the cable guiding piece is clamped with the cable guiding piece when the cable guiding piece is unlocked. The novel design is exquisite, the operation is simple, and the cable threading operation can be easily completed by a diver, so that the salvage process is simplified, and the operation difficulty is reduced; when the novel fishing tool is used, complex operation is avoided, so that the safety of fishing operation is also improved; the novel portable is small, and convenient dive is used. However, through practical use, the patent technology has the following technical problems:

(1) The driving mode is single. The primary product is driven by manpower, and the action is completed through the grab handle part of the manual rotating device. However, the underwater operation environment is complex, the rotary grab handle is laborious and large, the grab handle surface is smooth, and the slipping phenomenon can occur under a certain environment, so that the threading work cannot be completed.

(2) The overall mass is excessive. The primary product considers the problem of structural strength, stainless steel materials with higher strength are selected, the density of the stainless steel materials is 7.75X103 kg/m ³, all the components are solid, the whole mass of the device is overlarge, the whole weight in the air of the device is measured to reach 19.3kg, the weight in the water is calculated to be 16.8kg according to the weight loss coefficient in the water, and the diver has larger practical difficulty in underwater use.

(3) The transmission efficiency is too low. The internal threaded rods of the primary products are dense, so that people rotate the grab handles for a plurality of turns in the using process, but the corresponding clamp movement is not obvious. Through practical measurement, the rotary grab handle rotates 360 degrees, and the threaded rod moves by 1.58mm.

(4) The reliability in silt environment is poor. When operating in a sediment environment, sediment can block the butt joint position to cause butt joint failure. Through experiments of primary products, sediment can enter a round hole (namely an inner hole of a connecting pipe) on a cable guiding piece clamp in the butt joint process when the small-sized sediment is salvaged in sediment, and the round hole is blocked, so that the cable guiding piece cannot be in butt joint with the cable guiding piece. In actual operation, the sediment environment is unavoidable, the salvaged objects are trapped in the seabed sediment, and the problem of sediment blockage must be solved.

(5) The cable guiding piece is connected with the connecting pipe only through the positioning tongue, and is easy to fall off in actual operation, so that cable penetrating failure is caused.

In this respect, we have improved on the basis of this device, solving the above-mentioned drawbacks and applying the device extension to a remotely operated vehicle.
