Description
Technical field
This patent belongs to the nuclear energy security fields.The safety of nuclear power station is extremely important, and it directly affects the stable of the development and national economy and the popular feeling.This patent relates to design and the manufacturing of seismic isolation apparatus (two schemes), design and the manufacturing and the patent working scheme of tsunami protector.
Background technology
The Fukushima, Japan nuclear power station by heavy damage, and suffers that tsunami attacks, and causes serious nuclear leakage in 9 grades of special violent earthquakes; Wine becomes tremendous economic loss and popular feeling fear; For the moment, each big country of the world queries to nuclear power one after another, and China has also suspended the construction process of nuclear power station.Nuclear power is a kind of cleaning, efficient, safe green energy resource, and this is sure, so earthquake, tsunami damage wine to nuclear power station and become serious consequence; Be because protection is improper, measure is unfavorable; Being external cause, is not nuclear power self existing problems, in the energy deficient day by day today; Facing energetically, is unique selection.
Summary of the invention
Nuclear energy power generation facility and supporting facility thereof (hereinafter to be referred as nuclear power plant) are the priority of protections of nuclear power station; The seismic isolation apparatus and the tsunami protector of this patent design are based on preventing more than 8 grades that special violent earthquake that epicentral intensity 11 degree are above and tsunami and other secondary disaster damage nuclear power plant and design.
1. the general introduction of seismic isolation apparatus:
The failure stress of earthquake results from the earth's core, reaches in ground, and at ground with build between the building on the ground and to produce " shearing force ", therefore, building ruined degree in earthquake depends on the size of shearing force.A series of devices are installed between ground and building, shearing force and other failure stress are consumed in wherein, building then exempts from destruction, Here it is we " spacer assembly " that will pursue.
Propagation of seismic wave, elastic deformation also vertically takes place in along continuous straight runs occurred level distortion mostly.Because sudden change appears in the vibration period of seismic wave at any time, amplitude is suddenly big or suddenly small, and acceleration also has very unexpected sudden, makes human feeling simply helpless, and is hard to guard against.Useful in recent years " laminated rubber bases " is installed in the precedent between ground and the building as seismic isolation apparatus; To reducing shearing force, it is effectively alleviating the building damage, still; Its elastic deformation function and elastic return function are relatively poor relatively; Still be not enough to defend the more earthquake of large level and the destruction of secondary disaster, and the earthquake that earthquake magnitude is not too big just possibly cause the interlayer be full of cracks to it.We can't know that the earthquake that will take place future is much ranks; Therefore, the antidetonation standard setting of building in 8 grades may not necessarily " carefree ", particularly to nuclear power station and other mechanism relevant with nucleus product; Must guarantee the safety in crushing special violent earthquake; This just requires spacer assembly not only must possess very strong load-carrying ability, also must the contingent at any time amplitude peak of reply, the most complicated horizontal distortion and elastic deformation, and leave abundant leeway.
2. the design of spacer assembly:
(1) design scheme:
Scheme one: the main body of spacer assembly is formed " spring buttress " (like Fig. 2-2) by tens semielliptic spring steel plates; This spring buttress designs with reference to heavy type mining dump truck steel spring plate; It had both had powerful load-carrying ability, had very excellent elasticity distortion function and elastic return function again.The back of a bow of spring buttress is fixed on " load support " by " fastener " (like Fig. 2-4) and goes up (like Fig. 2-1); This support is cast in the steel concrete " bearing tray " (like Fig. 2-3) of bearing load; When earthquake takes place, rely on spring function and elastic return function to dissolve " elastic deformation ".Two " bow pin " of spring buttress are respectively adorned " carrying coaster " (like a Fig. 2-7), and the bow pin steadily is placed on the main body of this coaster, and is fixed by fastener.Carrying coaster main body the latter half is 4 " brave legs ", and its brave pin steps down in circle (or oval) " cast iron base plate " and goes up (like Fig. 3-4), is fixed by fastening bolt.Cast iron base plate periphery; Be " universal caster wheel central shaft through hole " (like the Fig. 3-7) that wears prominent edge on tens; Each through hole is installed 1 special " universal caster wheel " (like Fig. 3-5), can go up (like Fig. 3-6) in " plate platform " of foundation surface and freely roll, when earthquake takes place;, " straight line " (or curve) of horizontal distortion motion changing into original place " rotation " motion the horizontal distortion of any direction of ground conduction, any length, any speed is dissolved by universal caster wheel.
Scheme two: the main body of this scheme is " double-deck cylindrical helical compression spring " (like Fig. 4-3), and compression spring specification should be greater than the specification of train railway carriage shock-absorbing spring.What be used for installing the compression spring is that diameter is not less than " open circles cast iron disk " (like Fig. 4-2) that 2000mm, thickness are not less than 30mm; Be uniformly distributed with two rows on the cast iron disk closely and be no less than 50 " spring seat " (like Fig. 5-4); The compression spring is placed in the spring seat, is fixed by briquetting.At inboard and peripheral " universal caster wheel central shaft through hole " (like the Fig. 5-3) that wears prominent edge on 50 that be uniformly distributed with of cast iron disk, be used for installing " universal caster wheel ", when earthquake takes place, upward freely roll in " plate platform ".Above the compression spring, be " inverted cast iron disk " (like Fig. 4-2), this disk is cast in the steel concrete " bearing tray " (like Fig. 4-1) that carries nuclear power plant, need guarantee solid and reliable.In cast iron disk middle part, be " compound pier damper " (like Fig. 5-2) residing position, in order to increase the damper height, the load support that damper is installed is cast in the intermediate recess place (like Fig. 4-7) of bearing tray and spacer assembly corresponding position.
More than two kinds of schemes length is relatively respectively arranged, the former support degree is strong, good stability, still, directional selectivity and impact toughness are not as good as the latter.The latter because compression spring self just possesses the selection function of any direction, can assist the universal caster wheel travel direction to select the moment dead angle that occurs when avoiding the choice direction of earthquake initial period universal caster wheel.
(2) in this patent; " universal caster wheel " is very important ingredient; It not only will carry all wt of nuclear power plant, spacer assembly, tsunami protector, when earthquake takes place, also will directly face elastic deformation powerful, that undergo mutation at any time and horizontal distortion; So, in design, must be principle with " supporting capacity is strong ", " solid and reliable ", " direction selection function and running roller rolling function must flexibly ".What patent adopted is the universal caster wheel (like Fig. 6) of " inverted pendulum gyroscope " formula, and this universal caster wheel supporting capacity is strong, and can do to rotate along " central axis " (like Fig. 6-1) unlimitedly.Because two " planet running roller " (like Fig. 6-8) are urged on " plate platform " by gravity, when straight-line rolling, the frictional force between planet running roller and the plate platform is in balance; Initial period in that earthquake takes place because direction is suddenlyd change, causes frictional force unbalance; At this moment, under the driving of ground mental and physical efforts, till the planet running roller then turns to the frictional force balance along central shaft; And along continuous straight runs rolls, in face of powerful ground mental and physical efforts, and this turn to and rolling is easy to do.In design, the steering locking angle degree of planet running roller is 90 °, changes once this vertical angle takes place; Will produce the central axis axle center and two planetary rollers wheel shaft axle center overlap phenomenon with vertical line, cause of short durationly, increase failure stress the planet running roller perpendicular to the dragging of planet running roller transverse horizontal line; For this reason; In design, with two planetary rollers wheel shafts respectively left, dextroposition is not less than 5 °, meet on same the vertical line with the axle center of avoiding three axles.
In order to improve the height of central axis, guarantee that the universal caster wheel central axis has the more ability of the anti-horizontal distortion failure stress of formidable enemy, designed " prominent edge " (Fig. 6-3) of corresponding height in the central axis through hole of cast iron base plate; For reduce the multi-axis foot polling to the time resistance, central axis the first half and prominent along between, " central axis copper sheathing " (like Fig. 6-4) arranged, and keeps lubricating status for a long time; In upper and lower two positions of central axis " crossette ", " pressure bearing " (like Fig. 6-11) and " thrust ball bearing with flat seat " (like Fig. 6-10) of corresponding specification is installed respectively; For improving anti-the jolt ability of universal caster wheel in horizontal distortion, between thrust ball bearing with flat seat and " universal caster wheel main body " (like Fig. 6-7), lay two " spring washers " (like Fig. 6-6), move axially by a small margin along central axis to order about universal caster wheel; " spacing jump ring " (like Fig. 6-2) arranged on the central axis top, be used for the amplitude that moves axially of central axis is limited within the elasticity distance of spring washer.The agent structure of universal caster wheel and assembly method (like Fig. 7).
Super-huge, large-scale, medium-sized, small-sized four models that universal caster wheel has consider that from load-carrying ability and flexibility patent has been selected medium-sized, with the quantity of increase and decrease universal caster wheel, with the Load Control of universal caster wheel in 350～450kg.
(3) be fixed on " plate platform " (Fig. 1-7) of foundation surface; The levelling bench of flexible rolling not only is provided for universal caster wheel; The ground of the certain amplitude that occurs after also imperial anti-macroseism ftractures or dislocation is sagging by a small margin, and the destruction of spraying water, emitting husky secondary disaster that nuclear power plant is caused.
(4) below the spring buttress back of a bow, installed diameter be 500～800mm, " matrix " be cylindrical " compound pier damper " (Fig. 2-6) of resin and plastic; Its " enhancing body " adopts line style " three-dimension integrally programming structure "; Forming technology adopts " RTM forming technique ", and its complex method is " decentralized ".The damper shape is fairly simple, still, in earthquake, possibly be subjected to immense pressure at any time, so, knitting skill it must be emphasized that " globality ", split to avoid that the sound of sth. throbbing or bursting takes place.The height of damper is looked back of a bow height, the compression limit height when carrying coaster height and static state is confirmed, its upper end is installed in the fastener (Fig. 2-4) of spring buttress or is directly installed on the bearing tray, and the lower end then vertically urges on plate platform.The characteristics of this damper are: rely on the viscoelasticity of its internal construction, play the energy-dissipating and shock-absorbing effect; Its lower end is globular model, and there is little hemispherical " depression " in the centre, and is fixed because of this place's generation pull of vacuum during pressure-bearing, plays fixing and positioning action; When especially big amplitude elastic deformation takes place, can overcome pull of vacuum easily damper is mentioned, damage avoiding; When especially big horizontal distortion takes place, can be dragged displacement easily, also avoid damaging.
(5) spacer assembly takes place in no earthquake; When being in the inactive state of counterweight balance; Its " load load center of gravity " residing position is at 1/2 place that spring is piled up neatly the maximum flexibility deflection of (perhaps compressing spring) and damper, if deviation appears in this position; Then pass through amount number, width, the thickness of increase and decrease steel spring plate, and the quantity of increase and decrease compression spring is adjusted.
(6) in general arrangement, per 2 pairs (or 3 pairs) spring buttress and 2 (or 3) dampers are one group, and its area occupied is not less than 4m2, leave between each group and are not less than the wide passage of 800mm.During operational version 2, then each cast iron disk is one group, and other is identical with scheme 1.
(7) the nuclear power factory building is more than the 1000mm from the distance of perimeter stops cob wall, and several " elasticity thrust terminator " (like Fig. 1-6) are installed on retaining wall, and its minimal elastic stroke is 1000mm, and this thrust terminator has only thrust, does not produce pulling force.The thrust terminator effect is following:
1. when no earthquake takes place, jointly the what centre position is located by nuclear power plant with the damper in the spacer assembly;
When 2. earthquake takes place horizontal distortion is produced check and balance;
When 3. tsunami or strong storm took place, by the spring function of thrust terminator, for nuclear power plant provides a stifled soft stop protection wall, and driving nuclear power plant set back at once.
3. the design of tsunami protector:
Nuclear power station is mostly built the coastal waters in, to satisfy the demand of a large amount of cold true water.We guarantee the safety of nuclear power plant in the special violent earthquake through spacer assembly; But can not avoid because of tsunami, strong storm tide and the floods that special violent earthquake causes, the destruction that disaster caused by a windstorm causes nuclear power plant; Therefore, tsunami defence engineering is to guarantee the important step of npp safety operation equally.
The tsunami protector does not have beam column factory building (like Fig. 1-1) with a hemispherical in fact exactly, and nuclear power plant is covered in the factory building.The nuclear power factory building is very good by toughness, body is light, firm no fragility, the moulding of not chapping, can cold pressing do not rebound " thickening type plastic clip aluminum composite plate " makes and forms, and it has special method of attachment, can make the no beam column factory building of any radius.Because of this factory building itself just has very good resistance to shock,, also can be fixed on the retaining wall of periphery so it can be fixed on the bearing tray.
The matrix adopting PE of plastic clip aluminum composite plate at first is heated to molten state with base-material and is extruded by extruder as base-material (also can adopt other resin and plastic), carries out compound with the enhancing body that soaked glue; So repeat n time, after repeatedly exerting pressure, water-cooled is shaped; Because strengthening body, it adopts the punching aluminium strip; To strengthen in the body parcel what body so make matrix pass through hole, produce the effect of mutual containing, so; This complex method is " a decentralized complex method ", and this is the NEW TYPE OF COMPOSITE sheet material that a kind of composite performance is good, do not chap.The design thickness of this plate is 100～150mm, strengthens 8～12 layers of bodies, and (strengthening body thickness is 0.8～1mm).Although the plastic clip aluminum composite plate itself has multinomial hidden function; Can suppress some ray; But, produce the nuclear radiation that nuclear leakage causes in order more effectively to drive anti-maintenance, refuelling rod, process nuclear waste material and other work, again in the inboard of this composite plate; Compound 1 layer thickness is " lead foil " of 0.2～1mm, for nuclear power plant sets up the 5th layer of nuclear safety containment vessel.
With the plastic clip aluminum composite plate hexagon (or quadrangle) " tile " (like Figure 12) that to be cut into relative two back gauges be 2000mm, be cold-pressed into arc (also can use plate shaped tile) according to the radian of nuclear power plant designing; According to the radius (like Fig. 8-3) of nuclear power factory building and the distance on the relative both sides of tile; Draw " cutting angle on each limit of tile " (like Fig. 8-2); After this angle cutting,, " notch tenon " processing (like Fig. 9) is carried out on each limit of tile to be benchmark perpendicular to the cutting face; After the gluing splicing, be aided with " snap close " (like Figure 10-2).For strengthening being connected between snap close and the tile, two end faces that snap close is relative are cut into the chamfering (like Figure 11-1) of certain amplitude, and reinforce (like Figure 11-3) by " tension reinforcement plate ".
Method for embedding such as Figure 12 of nuclear power factory building tile need adhesive for spraying to each connecting portion, and every interface is installed and is no less than 2 snap closes.
