Description
Technical field
The utility model relates to floating nuclear power plant field, specifically a kind of fastening structure being applicable to packaged type floating nuclear power plant platform.
Background technique
Floating nuclear power plant can be used for generating electricity, desalinize seawater, heating, can meet the special requirement of block supply, district heating, offshore oil exploitation, chemical industry, polar region or remote districts, isolated island etc.Domestic for China, floating nuclear power plant can meet the fairly large demand to the energy such as island, oil drilling platform away from continent, for China coast Islands Exploitation, deep-sea oil gas exploitation provide the abundant energy in power supply, desalination of sea water etc., also can be used as military small cores power supply and apply on military base and island.At present, domesticly there is no marine nuclear power station that is in-service or that building.There is a floating type nuclear power station built in external only Russia in shipyard, the Baltic Sea.By update search, other technical paper about Russian floating nuclear power plant external can be searched, but be all the technological scheme of fixing boat form floating nuclear power plant based on offshore.
Sea floating kinetonucleus level platform is because of the rugged environment of ocean and the restriction of the decay resistance of self platform material, general actual life only has about 20 years, and according to the standard of three generations's nuclear power, the actual life of General reactions heap can reach 60 years, causes the effective storage life of floating nuclear power plant reactor will considerably beyond the service time of ocean platform like this.In order to better realize the utilization efficiency of floating reactor, improve its Economy, can consider that packaged type floating nuclear power plant designs, assemble again after nuclear island and platform are built separately, reactor can be separated after platform to service life above other platforms and continue to use.Adopting clamping bolt to connect, is a kind of simple and feasible Placement, both can ensure the soundness connected, and can be convenient to again follow-up dismounting and remove.In addition, general ocean platform size is more than 300M, steel safety shell height more than 30M, because of gigantism and the weight of platform and metal containment, installation specification requirement, need to adopt the clamping bolt of super large-scale to connect, general length more than 3 meters, the clamping bolt that diameter is 0.5 meter, weight can reach about 2t, because of weight relationships, at sea can be very inconvenient during installation screw.
But there is a lot of defects in the bolton mode of design at present: Attention problems does not have land convenient in the experiment using process of reality, limit the size of bolt, the fatigue aging of this outer bolt, sustained oscillation that when the continuous impact of seawater and reactor operation, flowing medium produces etc., capital produces platform and vibrates constantly, can loosened screw be caused, affect bolton effect, finally affect the fixing situation of reactor steel safety shell and platform.
Model utility content
The purpose of this utility model is to provide and is applied to a kind of fastening structure being applicable to packaged type floating nuclear power plant platform, solves the problem being difficult to operate, easily generation is loosening that current fastening structure exists.
The purpose of this utility model is achieved through the following technical solutions:
A kind of fastening structure being applicable to packaged type floating nuclear power plant platform, the platform comprise bolt column body, being connected by bolt column body and two nuts matched with bolt column body, described nut being evenly provided with multiple stove bolt hole, connecting by installing stove bolt in stove bolt hole between adjacent two nuts.The bolt connection carried out between component is adopted to be common technology means of the prior art, the compounding technique of screw bolt and nut is very ripe and be widely used, the floating nuclear power plant of China is when design, also be the structure that is connected being designed to adopt traditional bolts and nuts, do not go wrong in software simulation, also be and easy uncared-for technology point, but in the simulation using process of mockup, because the installation environment in sea floating power station is different with the installation environment of land, therefore, the installation difficulty of bolt is larger, and, the fixing bolt of this kind of platform, its diameter is larger, weight is larger, the installation difficulty of erection unit is more made to strengthen, if do not need dismounting and change, usually the mode of welding can be adopted to be fixed, avoid loosening phenomenon occurs, but need the requirement of dismounting at major diameter nut under, the technology that the fastening problems carrying out nut bolt at sea in float context can not used for reference, can be not for reference to the character introduction of this problem yet, in the simulation of reality uses, claimant has carried out large quantifier elimination to this problem, according to the marine situation and characteristic of reality, improvement is made to existing fastening structure: what utilize bolt screws principle, the end face of nut arranges multiple stove bolt hole, and by configuring the mode of structure of stove bolt, the multiple stove bolt holes arranged decrease the weight of mother nut, utilize the end face being fixed and dispersed within nut between being uniformly distributed nut of stove bolt simultaneously, area of contact between two nuts is increased, lifting surface area each other strengthens, greatly reduce the loosening possibility between nut, add the sealability of bolt entirety.
Described stove bolt is countersunk screw, and its top is provided with " ten " word notch or " one " word notch.Adopt the form of countersunk screw, the entirety that can realize nut meets usage requirement, and " ten " word notch or " one " word notch are set by the top of countersunk screw, the installing/dismounting of stove bolt can be carried out at platform surface, reduce further installation difficulty.
The rotation direction of described bolt column body is contrary with the rotation direction of stove bolt.By adopting the means that the rotation direction of bolt column body is contrary with the rotation direction of stove bolt, the sealability between nut can be improved, thus reduce the possibility loosened.
Many antiskid grooves are provided with at two end faces up and down of described nut.By arranging the mode of antiskid groove, the friction factor between two nut surface of contact can be increased, increasing surface friction drag, improve sealability.
Also comprise the elastic washer matched with described stove bolt.The effect of elastic washer improves prestressing force, can prevent stove bolt from loosening.
The utility model compared with prior art, has following advantage and beneficial effect:
A kind of fastening structure being applicable to packaged type floating nuclear power plant platform of 1 the utility model, according to the marine situation and characteristic of reality, improvement is made to existing fastening structure: what utilize bolt screws principle, the end face of nut arranges multiple stove bolt hole, and by configuring the mode of structure of stove bolt, the multiple stove bolt holes arranged decrease the weight of mother nut, utilize the end face being fixed and dispersed within nut between being uniformly distributed nut of stove bolt simultaneously, area of contact between two nuts is increased, lifting surface area each other strengthens, greatly reduce the loosening possibility between nut, add the sealability of bolt entirety,
A kind of fastening structure being applicable to packaged type floating nuclear power plant platform of 2 the utility model, by the top of countersunk screw, " ten " word notch or " one " word notch are set, the installing/dismounting of stove bolt can be carried out at platform surface, reduce further installation difficulty.
