Water and underwater dual-use sound and electric remote control release hook

Abstract

Acoustic and electric remote control release hook for both water and underwater, including a first shell and a cylindrical frame; the cylindrical frame and the first shell are detachably fixed, and the cylindrical frame is fixed with an underwater transducer , the underwater transducer is remotely paired with an above-water transducer, and the above-water transducer is connected with a control switch; the interior of the first housing is provided with an acoustic command receiving control module, and the acoustic command receiving control is connected to the power supply; the acoustic command receiving control module The underwater transducer is connected through a cable and a watertight connector, and the acoustic command receiving control module is connected with a DC motor. When it is used for water operation, it is the same as the traditional electronic remote control release hook, and when it is necessary to perform underwater release operation, it only needs to add and combine the transducer part, and cooperate with the water transducer to become a movable hook. The underwater acoustic remote control release hook, which can be quickly opened by acoustic commands underwater, realizes the multi-purpose in a true sense, greatly reduces operating costs, and improves operational safety at the same time.

Description

technical field [0001] The invention belongs to the technical field of ocean observation, and in particular relates to a release hook device which can be used both above water and underwater and is operated remotely through an electronic remote controller and an acoustic transducer. Background technique [0002] In the process of marine survey and observation, a variety of instruments or equipment are used. Because the heavy instruments or equipment such as gravity anchors are usually more than 2 tons, some even weigh 3 tons, they need to be released according to the location and environmental requirements. Generally, a winch is used to hoist the instrument or equipment out of the ship's side, and the fixed-point delivery is controlled by a mechanical or electric releaser. [0003] Existing mechanical releases include release hooks and mechanical locking devices, among which the release hooks commonly used in field work are manual pull wire or electronic remote control (inve...

AI Technical Summary

Problems solved by technology

[0004] The function of this release hook is relatively simple, and it can only realize the release operation on the water surface, and cannot work normally in seawater

However, in actual work, it often involves operations that need to be released underwater. For example, when deploying a seabed-based observation system, in order to ensure that its attitude is correct when it reaches the seabed, it must be lowered to the seabed using a winch and then released. To release, the currently commonly used method is to use an acoustic releaser to complete the release operation. This method requires a separate configuration of an acoustic releaser and a releaser deck unit, which greatly increases the operating cost

At the same time, it should be because the release device is too large and heavy, which is prone to danger in actual operation in high sea conditions
