Description
Technical field
Mended the invention belongs to damping element technical field peculiar to vessel, more particularly to applied to a kind of hydraulic pressure of vibration reduction of ship noise reduction
Repay buoyant raft caging system.
Background technology
For naval vessel electromechanical equipment vibration and noise reducing engineering, generally use vibrating isolation system carrys out vibration of the xegregating unit to pedestal and passed
Pass, and absorb energy caused by impact.In order to which limiting device is excessive by dynamic respond is produced during external impact load, more than setting
Standby and damping element maximum distortion, the displacement that limiter carrys out limiting device, such spacing category are installed generally in vibrating isolation system
It is passive spacing.With the intelligent popularization of the technicalization of vibration isolation equipment, the activeization design of caging system is also more and more important.
The content of the invention
In view of this, present invention aims at a kind of compensation hydraulic buoyant raft caging system is provided, rushed in vibrating isolation system
When hitting, hydraulic cylinder extension length can actively be adjusted according to the position relationship of buoyant raft, buoyant raft displacement will be compensated, and reach main
Dynamic spacing purpose, while and can meets security, reliability requirements.
Realize that technical scheme is as follows：
A kind of compensation hydraulic buoyant raft caging system, it include signal picker, signal processor, Pump Control device,
Hydraulic oil pump, hydraulic oil unit, hydraulic oil pipe, data signal line, N number of hydraulic jack and N number of displacement transducer；Wherein,
N number of displacement transducer is circumferentially disposed along float valve, and the side of each displacement transducer and float valve is at a distance of certain
Distance；N number of hydraulic jack is circumferentially disposed along float valve, and each hydraulic jack is formed one by one close to a displacement transducer
Corresponding relation, the side of N number of hydraulic jack and float valve are separated by a certain distance；N number of displacement transducer passes through data
Signal wire is connected with signal picker, signal processor successively；N number of hydraulic jack passes through hydraulic circuit and hydraulic oil pump phase
Even, the hydraulic oil pump is respectively connected with hydraulic oil unit and Pump Control device, the signal processor and the hydraulic oil
Pump controller is connected；

The signal picker, for gathering the displacement information detected by each displacement transducer, and it is transferred at signal
Manage device；
The signal processor, when the shift value for judging float valve, which exceedes, sets spacing value, generate control signal and pass
It is defeated by Pump Control device；
The Pump Control device, according to the control signal received, control hydraulic oil pump acts hydraulic jack, directly
Untill the displacement of float valve is less than spacing value.
Beneficial effect
