Product introduction

The SinoAR-05 mechanical ocean acoustic release device is a key system for the recovery of ocean observation equipment with mature technology and excellent performance. It is designed specifically for safe and reliable equipment release and recovery in complex and harsh marine environments such as deep seas, high pressures, and long cycles.

This release device creatively combines classic mechanical transmission mechanisms with modern acoustic remote-control technology, eliminating complex hydraulic oil circuits and fundamentally avoiding leakage risks, demonstrating extremely high system stability. Its core working principle is to receive specific encoded acoustic instructions from the deck unit, drive the built-in high-efficiency motor, and ultimately trigger a highly reliable mechanical release mechanism to achieve precise separation and upward recovery of tethered equipment (such as buoys, submersible markers, underwater observation platforms, etc.).

This release device has become an ideal choice for high-end marine applications such as deep-sea anchoring systems, bottom mounted observation platforms, geological exploration equipment, and polar scientific expeditions. It provides efficient, accurate, and worry-free equipment release solutions for marine scientists and engineers, greatly improving the success rate and safety of marine scientific expedition operations.

Composition and Overview

The SinoAR-05 release device mainly consists of the following parts:

Acoustic release composition structure

This mechanical acoustic release device is an underwater device triggered by sound signals, used to release loads or recover underwater equipment. The core of the equipment adopts a motor-driven rotary rod mechanism, combined with a balance bar and a locking hook to achieve efficient and reliable release operation. Its main structural components are as follows:

(1) Transducer: receives underwater acoustic commands and converts them into control signals.

(2) Control circuit: Receive signals sent by transducers to execute corresponding instructions.

(3) Drive: Drive the rotary lever to release according to the control signal.

(4) Decoupling: Used to fix the load and decouple after triggering the release signal.

(5) Shell and sealing components: provide water pressure resistance protection and adapt to underwater use environments.

The core execution component adopts a precision mechanical structure design and is directly connected to the motor drive module. After receiving the release command from the control module, it is unlocked by the motor drive mechanism to achieve safe and fast release of the load equipment. It has the characteristics of high unlocking accuracy, fast response speed, and stable locking state.

Core strengths

Simultaneously supporting remote command release and timed automatic release; while providing operational flexibility, it ensures the safety redundancy of critical equipment and data recovery.

(2) Powerful networking capability

With advanced coding technology, it can support 120 launchers to work together in the same sea area without interfering with each other, achieving large-scale and high-density deployment of observation networks.

(3) High reliability guarantee

Equipped with automatic self check function when powered on, it can quickly diagnose the status of core components, ensuring that the equipment is always in the best working condition before deployment and reducing task risks.

(4) Intelligent state monitoring

Provide distance measurement function, allowing users to remotely monitor the distance between the device and themselves, providing critical data support for task decision-making.

(5) Communication security and reliability

Adopting encrypted instructions and status feedback mechanism to ensure that operation instructions are not mistakenly triggered and the execution results can be confirmed in real time.

(6) Convenient maintenance and high reliability

The built-in rechargeable battery significantly reduces maintenance frequency and sealing risks caused by cabin replacement, and improves the reliability of long-term deployment.

(7) Excellent environmental adaptability

Adopting pressure resistant and corrosion-resistant materials and a wide temperature range design, it can operate stably in extreme environments from shallow waters to full sea depths in global waters.

Software

Mainly used for synchronizing release time and setting release time

Serial port selection interface

Open the software and click on 'Set time from PC' to synchronize the computer's time with the acoustic release device;

Time synchronization interface

Automatic release time setting: modify the time in ‘Popup time’, and then click the ‘Enter’ button. The modified time is the time when the acoustic release device automatically releases.

Automatic release time setting interface

Power consumption and supply

(1) The working parameters of the SinoAR-05 mechanical marine acoustic release device under different power consumption states using its built-in battery power supply mode are as follows:

Table 6.1 Power consumption status parameters

Power consumption status	Power consumption value	Instructions
static power consumption	≤5mA	The device is in standby mode, only maintaining the basic operation of the acoustic receiver and control module, without performing release or ranging operations.
Distance measurement power consumption	≤20mA	The device performs distance measurement function, and the acoustic receiver continuously receives signals and calculates distance. The control module processes distance measurement data in real time.
Release power consumption	≤50mA	The device performs active or timed-release actions, the motor drive module starts, and the mechanical release mechanism is driven to unlock.
Sleep mode power consumption	≤1mA	The device is in a deep sleep state, retaining only the battery level monitoring function, suitable for scenarios that do not require frequent monitoring during long-term anchoring operations.

(2) Supply voltage range

The main power supply battery voltage is 16.8V, and the motor power supply battery voltage is adapted according to the motor voltage. The voltage of this motor power supply battery is 37.8V, which is compatible with different specifications of rechargeable lithium battery packs or dry battery packs.
