Embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
Dam damping facility as shown in Figure 1, Figure 2, Figure 3, Figure 4 and monitoring system, including at least two sections of adjacent monoliths
Dam crest 4, including damper 1, damper installation cavity 5 are provided between the monolith dam crest 4, the damper 1 is arranged at damping
It is close to respectively with monolith dam crest 4 in the device installation cavity 5 and both ends of damper 1.
In actual use, once earthquake arrives, its vibration energy can largely be damped device 1 and absorb, so as to effectively drop
Weir section is rocked, so as to ensure the safety of dam body to greatest extent.One big advantage of the utility model structure design is to existing
Structured change is small, is easy to the Late reformation of most existing dam bodys, and anti seismic efficiency is obvious, has very wide city
Field promotion prospect.In general, when being constructed to arch dam, the reserved hole of damper can be set between monolith dam crest 4 in advance,
I.e. described damper installation cavity 5 is the reserved hole of the damper being arranged between monolith dam crest 4, as shown in Figure 1, then will damping
Device 1 is arranged in the reserved hole of damper.
In order to be monitored in real time to above-mentioned dam body vibrations even displacement, such scheme can be selected；The damping
Displacement transducer 11 is provided with device 1.As shown in Figure 4, the generally preferably magnetorestrictive linear displacement sensing of displacement transducer 11
Device, then coordinate grating strain gauge 12, you can accurately vibrations are monitored.In practice, can so operate：Every
4 dampers 1 are set in individual damper installation cavity 5, point two layers of installation.Pass through the speed of relative motion phase and the damping of damper
Coefficient carries out the calculating of damping force size with damping exponent.Such monitoring system have relative displacement to damper both ends,
The many indexes such as acceleration, amplitude, damper piston power, the temperature of damper oil cylinder carry out data acquisition, statistics, storage, point
The function such as analysis and output.Precision and lightning protection need to meet related specifications requirement, and damper Monitoring Data frequency acquisition should be with
The monitoring of dam strong-motion instrument is synchronous, is preferably acquired by 0.1s/ times, while data storage system should meet to be more than 15 days consecutive numbers
According to the requirement of storage area.Corresponding interface is reserved in the monitoring of dam damper, with Hydropower Project Safe Monitoring Automatic System
Connect, Monitoring Data reaches automated system monitoring integrated management, implements control and monitoring to each measuring point of whole system.To damping
During use, if occurring to timely respond to during seismic wave, Monitoring Data tracks device in time, guarantee damper stable performance, at work
In controllable state.
As shown in Figure 3, in order to ensure the stabilization of the installation of damper 1, can select to allow the both ends of damper 1 respectively to lead to
Cross ears ring seat 2 and be fixedly installed on monolith dam crest 4.Further, can also set up be fixedly installed on it is pre-buried in monolith dam crest 4
Part 3, the ears ring seat 2 are fixedly installed on monolith dam crest 4 by built-in fitting 3.
A spotlight of the present utility model is：Anti-seismic damper is arranged on Hydropower Buildings at present and carries out antidetonation monitoring
It is the first at home；Second equipment when being the superior of control mode, i.e. violent earthquake is in halted state, while protection equipment
Do not add excessive impulsive force to dam building, and building rocks after earthquake, the conversion of active state, damping device production
Raw corresponding action, rapid weaken are rocked.Therefore after damper is used on hydraulic structure, we avoid the need for again apprehensively
Shake energy is excessive and hydraulic structure is destroyed.
