Deepwater pressure-proof circular-opening flange butt-joint deadlock kickoff mechanism

Abstract

The invention relates to a deepwater pressure-proof circular-opening flange butt-joint deadlock kickoff mechanism. The deepwater pressure-proof circular-opening flange butt-joint deadlock kickoff mechanism comprises a pressure-bearing cylinder body, wherein the pressure-bearing cylinder body is formed by welding flanges in a butt-joint manner, the butt-joint surfaces of two ends of the pressure-bearing cylinder body are respectively sealed through sealing rings, and then the two ends of the pressure-bearing cylinder body form protruded circular-opening ends after being connected; a clamping ring is arranged on the peripheral surface of the pressure-bearing cylinder body and is divided into an upper half clamping ring and a lower half clamping ring, two ends of the clamping ring form a sunken circular slot after the upper half clamping ring and the lower half clamping ring are butt-jointed, and the sunken circular slot and the protruded circular-opening ends of the two ends of the pressure-bearing cylinder body are propped against in a matching manner and are sealed through the sealing rings; and one end of the clamping ring is fixedly connected with a blasting bolt after the clamping ring is connected, an opposite surface of the other end of the clamping ring in the sunken circular slot is further provided with a groove, two sidewalls of the groove are provided with through holes, and the groove is internally provided with a tension spring and is fixedly connected with the upper half clamping ring and the lower half clamping ring through pin shafts. The deepwater pressure-proof circular-opening flange butt-joint deadlock kickoff mechanism disclosed by the invention has the advantages of stronger forming processing property, maneuverability, safety and reliability.

Description

technical field [0001] The invention relates to deep-sea equipment and marine structure docking and connection channels, in particular to a deep-sea pressure-resistant circular flange docking lock release device that facilitates the release of underwater structures and the safe evacuation of divers' living quarters. Background technique [0002] The safety and reliability of deep-sea structures are related to the performance of deep-sea structures and the safety of underwater workers. At present, the requirements for the refinement of functions of underwater structures are getting higher and higher, which puts forward new requirements for deep-sea equipment and vehicles. and challenge. With the development and utilization of resources such as deep-sea oil, the laying requirements of submarine pipeline systems have also put forward higher requirements with the frequent occurrence of extremely harsh environments. [0003] In the prior art, it is difficult to release the escap...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the above-mentioned disadvantages of deep-sea structures such as difficulty in locking and releasing in the prior art, the applicant provides a deep-sea pressure-resistant round-mouth flange butt locking and releasing device with reasonable structure and convenient operation, thereby improving the reliability of the device. It reduces potential safety hazards and can be used for docking or connecting structures of deep-sea equipment and large-scale deep-sea complex multi-pressure body structures, as well as connection nodes of submarine pipeline systems
