Underwater equipment releasing device and releasing method thereof

Abstract

The invention discloses an underwater equipment releasing device and a releasing method thereof. The underwater equipment releasing device comprises a sealed cabin, a power driving mechanism and a hook releasing mechanism, wherein the power driving mechanism is arranged in the sealed cabin, and the hook releasing mechanism is arranged on the sealed cabin; the power driving mechanism comprises an electromagnetic releasing device and a torsion spring rotating unhooking device; the torsion spring rotating unhooking device comprises a releasing column, a torsion spring and a swinging rod; the releasing column is rotationally mounted on the sealed cabin; the upper part of the releasing column is exposed out of the sealed cabin; the lower part of the releasing column is positioned in the sealedcabin and fixedly connected with the swinging rod; the torsion spring sleeves the releasing column; one end of the torsion spring is fixed to the sealed cabin; and one end of the torsion spring is fixed to the swinging rod. According to the underwater equipment releasing device, through combination of an electromagnet and the torsion spring, the releasing purpose is realized; and meanwhile, the impact releasing of a torsional force can prevent the releasing column from being held by underwater shell fishes for a long time; and therefore, the failure of the releasing device is avoided.

Description

technical field [0001] The invention belongs to the technical field of underwater operation equipment, and relates to a device used for a seabed observation network and a marine pasture, in particular to an underwater equipment release device and a release method thereof. Background technique [0002] In applications such as marine environment monitoring, underwater target detection, and exploration and development of seabed resources, many devices are deployed below the sea surface and require regular recovery and maintenance. The commonly used underwater release devices are mainly acoustic release devices. This type of acoustic release device is expensive, bulky, and has a relatively complicated structure, and most of them are imported equipment. Patent CN201710090394.8 discloses an underwater release device, which presses the rope tightly on the resistance element, and burns the rope through the short-circuit heating of the resistance element on the circuit board, and the...

The commonly used underwater release devices are mainly acoustic release devices, which are expensive, bulky, and complex in structure, and most of them are imported equipment

Patent CN201710090394.8 discloses an underwater release device, which presses the rope tightly on the resistance element, and burns the rope through the short-circuit heating of the resistance element on the circuit board, and then releases the article. Need to use a new rope next time to hang items, resulting in waste and inconvenience

Moreover, the release device of the prior art still has underwater biological adhesion (such as sea oysters, sea rainbows and other shellfish) during use, and the device cannot be recovered due to release failure.
