Description
Technical field
The utility model belongs to radiation protection technique field, is specifically related to a kind of radiation shielded device.
Background technology
Nuclear power plant or other nuclear facilities generally adopt the radioimpurity radioactive impurity be detained in water filter filtering part radioactive water system, thus reach the object purified water, and after the pressure reduction of used filter core or radioactive level reach setting value, filter core can be replaced rear discarded.
At present, changing filtrator and to give up filter core, is adopt gripping tool to be loaded in metallic shield bucket after capping and deliver to the mode that temporary library keeps in carry out processing by shielding bucket.But, owing to opening filter cover and the radiomaterial captured in filter core process in filter core environment and personnel can discharge certain radioactivity towards periphery, be unfavorable for handling safety.Therefore, one is needed can to shield radioactive shield assembly in more renew cartridge operating process at present.
Utility model content
(1) utility model object
Problem existing for prior art, the utility model provides a kind of shield assembly that effectively can shield radioactivity, reduce dosage suffered by surrounding environment and personnel.
(2) technical scheme
In order to solve prior art Problems existing, the utility model is achieved through the following technical solutions:
A kind of radiation shielded device, this device mainly comprises upper cover plate, lower shoe, side plate, guide plate and barricade, wherein lower shoe is positioned at the below of upper cover plate and length is greater than upper cover plate, side plate is between lower shoe and upper cover plate, and side plate and lower shoe, upper cover plate form half-open cuboid structure; Upper cover plate is provided with the relevant position of lower shoe the duct be communicated with; The dual-side that lower shoe grows the part of upper cover plate is provided with guide plate; Barricade is cuboid structure, and between upper cover plate and lower shoe, the sidewall of barricade and bottom are provided with steel ball roller, barricade can be slided between upper cover plate and lower shoe and advance and pull-out; Lower shoe is also provided with postive stop baffle, prevents barricade from skidding off between upper cover plate and lower shoe;
Preferably, barricade is provided with handle.
Preferably, the top of upper cover plate is provided with the draw ring that can lift for lifting device.
Preferably, the material of upper cover plate, lower shoe, guide plate, barricade and side plate is lead.
Preferably, upper cover plate is provided with holding screw.
Preferably, upper cover plate is provided with register pin.
(3) beneficial effect
Nuclear power station more needs to open filter cover before renew cartridge and changes filter core, because whole Renewal process is when the protection not having shield assembly, can discharge a large amount of radioactive rays above filtrator.Adopt the radiation shielded device that provides of the utility model, the radioactivity that can effectively discharge in the filter element replacing process of shielded nucleus power station.Its mode of operation is mainly: after the hatch deck upper cover of opened filter ground, the shield assembly provided by the utility model is placed on above the hatch of ground that (now barricade is between upper cover plate and the duct of lower shoe, namely barricade is advanced state), then by the handle on barricade, barricade is drawn out to postive stop baffle position, gripping apparatus enters filter interior by the duct of upper cover plate and lower shoe and is caught to put into by the parts such as filter core and preserve container, after catching advances barricade to stop up duct in time.The material of this shield assembly is mainly lead, and shield effectiveness is good, solves and directly gripping apparatus is entered the large problem of the Radioactive Release that brings in filter cover.Meanwhile, the holding screw that this shield assembly is arranged is in order to fixed mask plate, avoids it in advanced state lower slider.
