Abstract

The invention discloses a nuclear power plant personnel gate sealing door locking mechanism, comprising: a power assembly (100), connected to an external power source, used to generate driving force driven by the external power source; a transmission assembly (200), connected to the The power assembly (100) is used to transmit the driving force generated by the power assembly (100); the transmission assembly (200) uses a commutator to realize the direction change of the driving force; the locking assembly (300) is connected to the The transmission assembly (200) is used to lock the airtight door (10) of the personnel gate to the door frame (20) under the action of the driving force. The invention simplifies the design, structure and on-site installation of the personnel gate sealing door locking mechanism of the nuclear power plant; and improves the transmission precision.

Description

technical field [0001] The invention relates to the field of nuclear power plants, in particular to a locking mechanism for a personnel gate sealing door of a nuclear power plant. Background technique [0002] The personnel gate runs through the double-layer containment and is part of the third safety barrier. Its main function is to allow personnel and small equipment to pass through when the reactor is running or thermally shut down, without damaging the sealing function of the containment. Due to the complex structure, strong logic and correlation of mechanism movement, and high pressure sealing requirements, the personnel gate is a large and complex mechatronic equipment with frequent failures, and the locking of its airtight door is very important. [0003] In the prior art, the locking mechanism of the personnel gate sealing door of nuclear power plant is mainly composed of a transmission commutator connected with the mechanical transmission mechanism of the personnel ...
