Description
Technical field
The invention belongs to technical field of nuclear power, be specifically related to a kind of antidetonation supporting structure.
Background technology
One of effect of reactor roof construction be limit control rod drive mechanisms (CRD) (CRDM) in the case of seismic events excessive deformation to maintain the integrality of function.Principle for seismic design is: in the case of seismic events, CRDM sends out upper end raw larger displacement, shock-proof plate on it will send out raw larger displacement with CRDM upper end, now shock-proof plate will with antidetonation loop contacts, force antidetonation ring also will be subjected to displacement, and antidetonation ring is fixed on rigidity encloses on cylinder preferably or be fixed on by antidetonation pull bar on the civil engineering structure in reactor refuling pond, limit the generation of displacement, thus limit shock-proof plate and CRDM upper end generation larger displacement, ensure that CRDM can not excessive deformation, maintain the normal function of CRDM.Therefore antidetonation ring serves very important effect in antidetonation process.
It is several that antidetonation ring at present in domestic and international presurized water reactor heap roof construction mainly contains square cross-section antidetonation sustained ring (the antidetonation sustained ring in distributing heap roof construction), antidetonation buffer structure (the antidetonation buffer structure in western room integration heap roof construction) and monoblock type shock-proof plate (shock-proof plate in roof construction is piled in western room in early days) etc.
Wherein antidetonation sustained ring is welded by four blocks of sheet materials, and section is tetragonal ring cavity structure, and this structure integral rigidity is high, but due to ring body size comparatively large, bring a lot of trouble to manufacture; And the buffer structure in integration heap roof construction, it is the square cross-section ring cavity structure be welded by three blocks of plates, whole ring cavity is bolted on the supporting station that encloses on cylinder, this structure needs three pieces of plate welding equally, centre is welded with gusset, during manufacture, welding deformation is difficult to control, and structure is comparatively complicated; Monoblock type shock-proof plate then by antidetonation ring and shock-proof plate integrally, is unfavorable for the adjustment in gap between shock-proof plate and CRDM, will produces adverse influence to CRDM.
Summary of the invention
The object of the present invention is to provide a kind of structure simple, and the presurized water reactor control rod drive mechanisms (CRD) tabular antishock device of distributing and integration two kinds heap roof construction can be met simultaneously.
Realize technical scheme of the present invention as follows:
A kind of presurized water reactor control rod drive mechanisms (CRD) tabular antidetonation ring, it comprises ring body, and be circular outside it, inner side is polygon, and four angles that described polygon is quadrilateral process two squares and formed, the ring body outside polygon is provided with hanger erection hole; Described each limit polygonal is provided with adjusting bolt and setting nut.
In above-mentioned a kind of presurized water reactor control rod drive mechanisms (CRD) tabular antidetonation ring: described hanger erection pore size distribution is as follows, on polygonal four limits of stroke, evenly processing 4 respectively, processes 1 in two right angles on each angle respectively.
In above-mentioned a kind of presurized water reactor control rod drive mechanisms (CRD) tabular antidetonation ring: described ring body is fixed with hinged-support, and the ring body of the position in hanger erection hole is respectively equipped with screw thread pressure strip and screw thread rest pad up and down.
In above-mentioned a kind of presurized water reactor control rod drive mechanisms (CRD) tabular antidetonation ring: the top surface edge of described ring body is processed with bolt connecting hole and pin-and-hole, arranges coupling bolt, arrange fixed pin in pin-and-hole in connecting hole.
Beneficial effect acquired by the present invention is as follows: the inner polygon of antidetonation ring is suitable for the structure of CRDM, quantity and position, setting nut inside polygon and bolt can regulate the distance between antidetonation ring and shock-proof plate, lower suspension rod is installed in hanger erection hole simultaneously on antidetonation ring, again by screw thread pressure strip and screw thread rest pad, antidetonation ring is supported and fixed on lower suspension rod, is beneficial to the adjustment in gap between shock-proof plate and CRDM.Further, in distributing is arranged, antidetonation ring installs hinged-support, can be connected with antidetonation rod assembly, antidetonation ring is transferred loads on reactor pit civil engineering structure by hinged-support and antidetonation rod assembly, thus arrives the object of restriction CRDM excessive deformation; In integrated arrangement, the edge, face, top of antidetonation ring is processed with bolt connecting hole and pin-and-hole, in connecting hole, coupling bolt is set, in pin-and-hole, fixed pin is set, antidetonation ring is transferred loads to by coupling bolt, attaching nut and fixed pin and encloses drum flange and enclose on cylinder, thus arrives the object of restriction CRDM excessive deformation.
