In every platform unit of nuclear power station, several radioactive water filtrator is all installed, in the ground steel case that the position of water filter generally locates below ground level, the chief component of filtrator comprises ground hatch deck, container upper cover, filter element retainer and filter core etc. according to sequence of positions from top to bottom, and wherein ground hatch deck is concordant with ground.According to nuclear power station regulation, filter element reaches all to be needed when differential pressure reaches setting value to change certain service time, and it is temporary just to need loading cask flask to be transported to refuse temporary library when useless filter element contact agent dose rate is greater than 2mSv/h.
In the mode of operation changing useless filter element be at present, transport vehicle is utilized to be transported to by filter core transporter on the steel case of ground, then utilize lifting device to be lifted after above filtrator transport vehicle is removed, then filter core transporter is placed on the steel case of ground.Because filter core transporter weighs 2.5 tons, and the limited space of nuclear power station, high to the requirement of lifting device.Therefore, need a kind of under the prerequisite guaranteeing radiation safety, do not need filter core transporter is lifted and the transport vehicle of filter element replacing transhipment can be realized.
Utility model content
(1) utility model object
Problem existing for prior art, the utility model provide a kind of radioactive shield effective, do not need by filter core transporter lifting and can realize filter element replacing transhipment transport vehicle.
(2) technical scheme
In order to solve the problem existing for prior art, the technical scheme that the utility model provides is as follows:
A kind of transport vehicle of give up for nuclear power station filter element transhipment and replacing, this transport vehicle comprises sweep, wheel, motor, differential mechanism, power supply and switch board, wherein sweep is rectangle sweep, power supply and switch board are positioned at one end above sweep, and motor, differential mechanism are fixed on the below of sweep.Key is, sweep is also provided with cuboid groove, and the middle part of groove is provided with duct, and the below in duct is provided with lead shield cylinder, and this duct and lead shield cylinder form the through hole run through, and filter core transporter is positioned over above duct.
Preferably, described shielding cylinder is connected by screw with between sweep.
Preferably, sweep is provided with lifting lifting ear.
Preferably, register pin is provided with in groove.
(3) beneficial effect
The transport vehicle that the utility model provides, its sweep top is provided with cuboid groove, filter core transporter can be positioned over the duct place above groove, so just achieve without the need to filter core transporter is lifted above filtrator, but on transport vehicle, just can realize the transfer operation of filter core, simplify operating process.Meanwhile, the radioactivity utilizing the lead shield cylinder below transport vehicle sweep farthest can reduce filter core to discharge in environment towards periphery.
Accompanying drawing explanation
Fig. 1 is the transport vehicle diagrammatic cross-section that this application claims protection, and wherein 1 is wheel, and 2 is sweeps, and 3 is grooves, and 4 is lead shield cylinders, and 5 is register pins, and 6 is power supply and switch board.
Embodiment
Below in conjunction with embodiment and Figure of description, the utility model is further elaborated.
A kind of transport vehicle of give up for nuclear power station filter element transhipment and replacing, this transport vehicle comprises sweep 2, wheel 1, motor, differential mechanism, power supply and switch board 6, wherein sweep is cuboid sweep, power supply and switch board 6 are positioned at one end above sweep, and motor, differential mechanism are fixed on the below of sweep.Key is, sweep 2 top is also provided with the groove 3 of cuboid, and the middle part of groove 3 is provided with duct, and the below in duct is provided with lead shield cylinder 4, and this duct and lead shield cylinder 4 form the through hole run through; Be connected by screw between lead shield cylinder 4 with sweep 2, sweep 2 top be provided with lifting lifting ear, be provided with register pin 5 in groove 3.
When adopting this transport vehicle to filter element replacing and transhipment, needs and ground make-up shielding device match, wherein the structure of ground screen device is: 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, and the top in duct is placed with lead; Described lead comprises internal layer lead, outer lead double-layer structure, and wherein internal layer lead is fixed sturcture, and outer lead is liftable structure; The dual-side that described 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.Described barricade is provided with barricade handle, the top of upper cover plate is provided with can for the draw ring of lifting device lifting, holding screw and register pin; The material of upper cover plate, lower shoe and guide plate is stainless steel; The material of barricade and side plate is lead.The lifting of described outer lead is realized by turning handle and the cam that is connected with turning handle, and outer lead is provided with self-oiling bearing, rises produced friction force for alleviating on outer ring.
The fit system of transport vehicle and ground screen device is:
In filter core transport process, ground screen device is positioned over above the hatch deck of filtrator ground, then utilizes transport vehicle to be transported to by filter core transporter above this ground screen device,
Before utilizing filter core shipping unit to capture filter core, turning handle and cam rise the outer lead of ground screen device, until outer lead has covered the lower limb of transport vehicle shielding cylinder, and then carry out grasping manipulation, this kind of mode can effectively avoid radioactive ray to leak between outer lead and transport vehicle shielding cylinder.
