The electro-corrosion acoustic release Ⅰ is the main equipment for Marine monitoring system recovery. The acoustic release Sino-AR developed by our company is suitable for the whole deep sea environment, and the maximum communication distance can reach 10,000 meters. The acoustic release device Sino-AR is mainly composed of three parts: acoustic transducer, acoustic release main board and release mechanism.

System integration: The three parts of the electro-corrosion acoustic releaser are relatively independent and can be flexibly compatible with the user's equipment. In particular, the release mechanism is often differentiated due to the differences in the equipment and application environment.

Load size: ≤500kg

Mechanism principle: the use of rotating rod structure, the use of torque to reduce the force of the trigger point; For the submersible mark with small load, the method of hook direct load can also be used;

Application environment: The equipment platform and the anchor are fully coupled, and the equipment is stationary in the seabed for a long time until it is released. It is limited to seawater and cannot be used in fresh water.

Advantages:

(1) Low cost

(2) The principle is simple, the system reliability is strong;

(3) Highly customized, high system integration;

The main difference between Type II and Type I is the design of the release mechanism. The sink holder usually has an inverted U-groove to release the hook. The inverted U-groove and the fuse breaker jam the release hook.

The seafloor seismograph is a typical glass-bottomed submarine marker, shown below, with the glass sphere itself 17 inches, providing equipment space and buoyancy. The acoustic release device of the submarine seismograph is integrated in each part, of which 5 is an acoustic transducer, 3 is an acoustic release device, and 12 is a fuse wire. The release mechanism is composed of a red bottom plate, a hook connecting the fuse wire and a rotary rod.
