Example Embodiment

[0024] The present invention will be further described below in conjunction with the drawings and embodiments.

[0025] Such as Figure 1 ~ Figure 4 As shown, the present invention is mainly composed of guide piece 1, cutting knife cavity 2, opening groove 2, retaining ring 3, cutting knife 4, breakable pin 5, sealing ring 6, piston pull pin 7, sealing ring 8, base 9, Ignition device 10, sealing ring 11, pressure ring 12, communication cable 13, watertight joint 14, gasket 15, gasket 16, sheath 17, pressure ring 18, sheath 19, breakable pin 20, screw 21, communication buoy 22 and other composition.

[0026] The base body 9 has a cylindrical structure and a smooth surface. The outer edge is evenly distributed with screw mounting holes. There is a ∏-shaped groove on one side, facing the hole on the vertical surface of the ∏-shaped groove, and a piston pin 7 with a sealing ring 6 Install from here, and then install the cutting knife 4 with the cutting edge 4a to the left; the watertig...

Abstract

The invention discloses an underwater cutting releasing mechanism which mainly comprises a guide sheet, a cutting knife cavity, a baffle ring, a cutting knife, breakable pins, a piston-type pull pin, a basal body, an igniter, pressure rings, a communication cable, a watertight joint, a sealing cushion, a gasket, protective sleeves, a screw, a communication floater, and the like. The underwater cutting releasing mechanism is characterized in that the appearance is in a cylindrical structure with a smooth surface; one side of the basal body is provided with a TT-shaped groove, a hole in the vertical surface of the TT-shaped groove is sequentially provided with the piston-type pull pin, the cutting knife, the protective sleeve, the communication cable, the baffle ring, the cutting knife cavity and relative sealing rings, and a hole in the horizontal surface of the TT-shaped groove is sequentially provided with the watertight joint, a sealing ring, the gasket, the protective sleeves and the pressure rings; and a passage structure is formed at the bottom edge of the basal body from a gas passage start in the mounting position of the igniter to a gas passage end in the position of the piston-type pull pin.

Description

technical field [0001] The invention relates to an underwater release mechanism, in particular to an underwater cutting release mechanism. Background technique [0002] The buoy on the deepwater platform is released by the underwater cutting release mechanism, which is a method of deepwater buoy release. Generally speaking, once the underwater cutting release mechanism is activated, it can realize two functions, one is to release the underwater communication buoy, and the other is to cut off the communication cable at the same time, so that the buoy carrying a large amount of marine environmental data can freely surface and complete Transmission of underwater information to the outside world. The present invention is developed on the basis of the original underwater cutting release mechanism, and has brand-new improvements in structure and action mechanism. [0003] The structural diagram of the original underwater cutting release mechanism is shown in Figure 5 , the sche...
