The invention discloses a secondary locking mechanism of an underwater horizontal connector installing tool. The secondary locking mechanism comprises a gear rack, a gear, a gear fixing shaft and a locking head, wherein the gear is fixed on the gear fixing shaft; when the gear rack is meshed with the gear, the gear fixing shaft rotates under the action of the gear; a compression spring is arranged inside a cavity of the gear fixing shaft; the locking head is arranged at one end part of the gear fixing shaft, and extends out of the gear fixing shaft; and the locking head can move along the axial direction of the gear fixing shaft under the action of elasticity of the compression spring. Without assistance of an ROV (remotely-operated vehicle), automatic locking is achieved in the installation process; and the locking head adopts a special columnar structure, so that the firmness after locking is ensured and the reliability of a whole connector is improved.
Description
technical field [0001] The invention relates to a secondary locking mechanism of an underwater horizontal connector installation tool. Background technique [0002] At present, the development of deep-water gas fields is a new field of energy industry with high investment, high risk and high-tech intensive. Among them, the locking of the subsea manifold connector is a key technology in the development of deep water gas fields. In particular, the secondary locking, which is inconvenient to operate, is a technical challenge to ensure the firm connection of the manifold. Whether this technical problem can be successfully broken through will directly affect the development and utilization of deep-water gas fields. Contents of the invention [0003] The purpose of the present invention is to provide a secondary locking mechanism of an underwater horizontal connector installation tool, which does not require ROV operation, is easy to operate, and has a high degree of automation...
