The invention provides a door lock device of a personnel air lock of a containment, and the door lock device is used for solving the technical problems that an existing door lock device of the personnel air lock is complex in structure, small in locking force and poor in reliability. The door lock device is provided with a support which is provided with a rotary shaft, and the rotary shaft is provided with a roller base which can rotate around the rotary shaft. The door lock device of the personnel air lock of the containment is further provided with a rack connecting rod. One end of the roller base is connected with the rack connecting rod, and the rack connecting rod can rotate relative to the roller base. A roller shaft is arranged at the other end of the roller base. The door lock device of the personnel air lock of the containment is further provided with an eccentric cam base which is provided with an eccentric cam surface. The door lock device provided by the invention can be widely applied to the field of locking devices.
Description
technical field [0001] The invention relates to a locking device, in particular to a lock device for a personnel gate of a containment vessel. Background technique [0002] We know that there is a personnel gate on the containment of the pressurized water reactor nuclear power plant. It is a passage for operation, security inspection, and maintenance personnel to enter and exit the containment during the refueling and operation of the reactor. It can also be used for some tools and instruments. Shipping of equipment. [0003] The door lock device is an important part of the transmission mechanism of the personnel gate. It can not only lock the two airtight doors of the personnel gate under the normal working conditions of the nuclear power plant, but also ensure the integrity of the containment structure, and it can also be used during shutdown and refueling, Unlock and release the locking function during maintenance, and open the two airtight doors through the transmission...
