Description
Technical field
This utility model relates to control rod in nuclear power station and drives field, is specifically related to a kind of CRDM vibrations and passes
Sensor mounting seat.
Background technology
In nuclear power station, regulated the heat outputting power of reactor, pushing turbine by the reactivity controlling nuclear reactor
Operating generates electricity.Control pile reactivity the most directly, the most quick mode be that regulation has the reaction of neutron-absorbing function
Heap control rod position in reactor core.
Control rod position in reactor core is to be realized by regulation control bar system CRDM i.e. CRDM.Rod control
System is CRDM coil power supply by high power module, makes two hooks within CRDM alternately
Adhesive, open, mobile, thus drive and hang over the control rod on CRDM drive rod in reactor core active region
Rise, lower insert and remain stationary as so that it is rest on the diverse location in reactor core, in order to absorb number of neutrons in various degree, thus
The reactivity of regulation reactor, and then the output of regulation reactor.
In order to improve the accuracy that control rod is controlled, must the most effectively perform suction by accurate measurements CRDM
Close, open and shift action, to guarantee CRDM accurate and effective execution control rod movement instruction.And control rod drives
The adhesive of motivation structure, the operating point opened and move must use special sensor i.e. shaking sensor to measure, by surveying
The vibrations of amount drive mechanism operating point are with the whether action of monitoring driving mechanism.
In nuclear power station, CRDM shaking sensor is arranged on custom-designed base, and base is fixed on control
In suspension ring outside rod drive mechanism upper run sleeve pipe processed.When CRDM runs, shaking sensor and suspension ring one
Play vibrations, therefore improve the standard of the tightness beneficially raising CRDM vibration monitoring that mounting seat is connected with suspension ring
Really property, meanwhile, sensor base also should possess the advantages such as reusable, easy to maintenance, easy for installation.
In nuclear power station, used a kind of shaking sensor mounting seat is spring-piece type before, this type mounting seat
Shortcoming is: less with suspension ring contact surface, affects the accuracy of vibration monitoring；Mounting seat shell fragment after repeatedly dismounting can produce not
Reversible elasticity deformation, reusability is affected；Lacking switching performance design, after installation, steadiness is poor etc..
Utility model content
The purpose of this utility model be solve prior art be hit by a bullet tandem mounting base and CRDM suspension ring it
Between contact area little, affect shaking sensor monitoring accuracy, there is irreversible elastic deformation after repeatedly dismantling, repeat to make in shell fragment
By the problem of property difference, and make to install between mounting seat and CRDM suspension ring more firm.
This utility model is achieved through the following technical solutions:
A kind of CRDM shaking sensor mounting seat, including the mounting seat for installing shaking sensor,
Also include fixing the connection seat being connected with described mounting seat, described connection seat and the CRDM suspension ring being set in outside it
Being fixed by pin, described connection seat forms vacant termination through the part of described CRDM suspension ring, described vacant
At described CRDM suspension ring, the horizontal pin preventing described suspension ring from sliding axially, pin are installed on termination
Making to connect seat can effectively be clamped in CRDM suspension ring, pin is arranged on the connection vacant termination of seat, prevents
CRDM suspension ring skid off from connecting the vacant end of seat, and from axially fastening CRDM suspension ring, above-mentioned
Technical scheme efficiently solves and is connected what seat rocked in CRDM suspension ring due to what product size error caused
Problem, this technical scheme has been effectively ensured the steadiness that sensor base contacts with CRDM suspension ring, has improve control
The accuracy of rod drive mechanism vibration monitoring processed.
As preferably, porose on mounting seat side, shaking sensor is installed in hole, and this technical scheme can effectively prevent
Owing to sensor is caused damage by external impact.
As preferably, mounting seat is provided with shaking sensor signal lead-out groove, it is simple to the extraction of sensor signal lines, anti-
Stop signal line is by foreign object damage.
As preferably, four angles of mounting seat side are gripping surface, and gripping surface is arc, and the program is easy to the installation of base
And dismounting, protection operator preserves from.
This utility model compared with prior art, has such advantages as and beneficial effect:
This utility model one CRDM shaking sensor mounting seat, sensor mounting seat and control rod
Drive mechanism suspension ring have large contact, contact more firm, it is to avoid the resonance caused owing to floor installation loosens, pole
The earth improves the accuracy of CRDM vibration monitoring, and meanwhile, multiple practicality and human oriented design are effectively shortened
The installation of base, maintenance time, it is ensured that it loads and unloads number of times, reduce use cost, and therefore this utility model has great practicality
It is worth.
