Fast-connection and anti-collision device of hydrophone on kevlar rope

Abstract

The invention discloses a fast-connection and anti-collision device of a hydrophone on a kevlar rope. The fast-connection and anti-collision device comprises an upper support and a lower support; a universal joint is arranged at the right end of the upper support; the right end of the lower support is provide with a round hole; a connecting frame is connected to the middle parts of the upper support and the lower support; hasps are fixed to the left sides of the upper support and the lower support separately; each hasp comprises an upper main hook body, a lower main hook body and a middle hookbody, wherein the middle hook body is located between the two main hook bodies; each middle hook body is connected between the right ends of the two corresponding main hook bodies and is provided with a torsional spring; the upper end of the hydrophone is suspended on the universal joint and penetrates through the round hole; a lantern ring sleeves the position, corresponding to the round hole, of the hydrophone; a damping ring is wrapped around the outer side of the lantern ring; and the hasps are buckled on the kevlar rope. The fast-connection and anti-collision device has the advantages that the hydrophone is not directly mounted on the kevlar rope in a suspended mode, when the kevlar rope inclines to a certain degree in the sea due to various sea conditions, a protection effect can beachieved on the hydrophone through the effect of the damping ring, the upper support and the lower support are buckled on the kevlar rope through the hasps, displacement in the rope direction cannotbe generated, and the position of the hydrophone is relatively fixed.

Description

technical field [0001] The invention relates to a quick connection and anti-collision device of a hydrophone on a Kevlar rope. Background technique [0002] At present, marine multi-channel seismic plays an important role in the investigation of marine geology and mineral resources. As a new type of high-resolution seismic signal receiving system, the anchored deep-sea sulfide seismic exploration data receiving device has gradually gained important applications in recent years. [0003] In the anchored deep-sea sulphide seismic exploration data receiving device, the hydrophone array is an indispensable core component in the data receiving unit, and it is mounted on a special Kevlar cable to cooperate in data acquisition. Currently the most commonly used hydrophone fixing solution is to use a thin Kevlar rope to wind the hydrophone in multiple turns, and then mount it on the main Kevlar rope bearing point with the help of a bracket. The current existing solutions have the f...

Problems solved by technology

However, at present, manual and mechanical hydrophone mounting / unloading adjustment schemes are mainly relied on. The work is cumbersome and time-consuming, and it also brings safety hazards to the shipside workers in poor sea conditions.

How to quickly and stably connect the hydrophone to the Kevlar rope, and quickly adjust the connection point of the hydrophone on the Kevlar rope is a very difficult technical problem in current offshore operations, which affects the efficiency and safety of offshore work
