Abstract
The utility model relates to a protection door for nuclear power station, particularly to a biological shielding door, which belongs to the technical field of special nuclear power door. The biological shielding door comprises a door frame fixed to a door hole on a wall body; the side edge of the door frame is hinged with at least one door sash; and the door sash includes a door plate. The improvement of the biological shielding door is that: the door sash is connected with the door frame through a homemade hinge; a contact surface of the upper part of the door plate and the door frame is provided with a door resistance; the inner and outer parts of one side of the middle part of the door plate far away from the hinged end are both provided with door handles; and the lower part of the door plate is provided with an inserted pin. The biological shielding door is simple in structure, convenient to manufacture and short in purchasing cycle, effectively meets the requirements of the doors with shielding radiation protection functions in different levels for nuclear power station, reaches the requirements of first nuclear safety level of nuclear quality assurance (QA) and can be widely applied to the field of construction of special door for nuclear power station in our nation.
Description
Technical field
The utility model relates to a kind of used in nuclear power station protective door, and especially the biological shielding door belongs to nuclear power special door technical field.
Background technology
Country's Eleventh Five-Year Plan is proposing aspect the nuclear power autonomy-oriented: realize the autonomous Design of advanced million kilowatt pressurized-water reactor nuclear power plant, autonomous manufacturing, independently construction and autonomous operation; Set up construction and the Management and Operation Model that integrates with international most advanced level comprehensively, form more complete autonomy-oriented nuclear power industrial system.And when the Daya Gulf of building in earlier stage, Qinshan and mountain range Australia first phase nuclear power station; Because domestic nuclear power corollary equipment design and fabrication technology is ripe not enough; So supporting nuclear power station biological shielding door is all by external import; Its procurement cycle is long, and buying expenses is high, and special door maintenance and maintenance work after putting into effect to nuclear power station bring a lot of difficulties.Therefore need domestic nuclear power undertaking of construction research nuclear power special door to manufacture and design advanced technology, further optimize and improve, improve the safety and the economy of nuclear power engineering, satisfy the autonomy-oriented demand of present domestic nuclear power station special door auxiliary products.
The utility model content
The purpose of the utility model is in order to address the deficiencies of the prior art, to propose a kind of biological shielding door, satisfying the technical requirements of nuclear power station special door.
In order to achieve the above object; The structure of the utility model comprises the doorframe that is fixed on body of wall door opening place; Hinged at least one door leaf of the side of said doorframe, said door leaf contains door-plate, and its improvements are: the contact surface of said door-plate top and doorframe is provided with a resistance; Said door-plate middle part is equipped with door handle away from inside and outside an of side of hinged end, and said door-plate bottom is provided with latch.
Wherein, the both sides inner edge of said doorframe and the inboard of top margin welding anchor, the outer end of said anchor is " Y " shape, is fixedly built in body of wall door opening place by stiffened panel.
Further, when adopting single door, the hinged door leaf of the side of said doorframe, said door-plate is near being provided with the lock nose between side of door handle and the doorframe.
Again further; When adopting double door; The dual-side of said doorframe is a hinged door leaf respectively, and said door leaf contains door-plate, and the upper and lower of one of them door-plate is equipped with heavy latch; Another door-plate is away from the side fixed cap seam plate of hinged end, the height of said lid seam plate and the height and the consistency of thickness of thickness and door-plate.
The biological shielding door of the utility model; Simple in structure, easily manufactured; The requirement of the different shielding radiation-prevention Performance Level of used in nuclear power station door is lacked, effectively satisfied to procurement cycle, reaches caryoplasm and protect QA1 level nuclear safety class requirement, can be widely used in China's nuclear power station special door construction field.
