Description
Technical field
The utility model relates to vibration absorber technical fields, and in particular to a kind of plane gate reversely supports vibration absorber.
Background technique
Plane gate because its structure and operating condition complexity so that its there is many safety are steady in engineering application
Qualitative question.Gate is when opening-closing process or part are opened, and when even closing water blocking, can usually generate vibration, vibration is tight
It may cause the flutter failure of gate when weight.In general the reason of plane gate flutter failure, has following several:
(1) severe flow condition causes radial gate vibration, if the main gate in some tunnels is in opening process, certain water
Flow under head and aperture makes downstream generate free pressure flow, and alternately bad fluidised form causes the violent whirlpool of water flow and blast fierce
Gate is impacted, gate is caused to generate strong vibration；Air height is compressed to form pneumatic hammer before some gates, with certain frequency to flat
Face gate causes the vibration that gate is strong with percussion；
(2) design of plane gate door body configuration of gate bottom is unreasonable, causes dynamic water vein dynamic pressure, or cause negative pressure and generate sky
Erosion, leads to gate judder；
(3) plane gate gate slot form design is unreasonable, when high-velocity flow is through lockage hole, since slot section boundary is prominent
Become, generating local pressure reduces, and cavitation occurs, causes cavitation erosion, and generates the high vibration of gate；
(4) gate aerial drainage under certain aperture, the submerged hydraulic jump occurred after lock can generate periodically impact to gate, this
Shi Shuiliu strong fluctuation pressure effect causes radial gate vibration.
The vibration of gate can cause light or heavy consequence, and less serious case will cause fatigue damage to gate self structure, weight
Person then will lead to other hydraulic structures and generate the crack even sedimentation of ground or dam abutment displacement, and therefore, gate is as water conservancy project knot
Important baffle device for water in structure, reliability of structure are largely fixed the operational effect or even prestige of hydraulic structure
Coerce the safety of other hydro-structures.
The reason of radial gate vibration, is sufficiently complex, but on the whole, be due to influence of dynamic water it is unstable caused by, work as gate
When contacting with dynamic water, it always will appear vibration.The vibration of gate, usually with gatage, submerged hydraulic jump, sealing leak, lock behind the door
The factors such as the influence of door root edge pattern are related.Engineering practice proves, when gate aerial drainage or gate in the operation of dynamic water by water flow
Different degrees of vibration can all occur when effect.Under normal circumstances, vibration is weaker, will not influence the safe operation of gate, but
Under given conditions, gate will generate judder, or even generate resonance or dynamic buckling phenomenon；Wherein harmfulness is maximum
The resonance that be then gate structure generate under the effect of special hydrodynamic load.
Currently, causing hydraulic gate judder for the effect of the Disadvantageous combination of hydrodynamic load and Structure Dynamic Characteristics
Basic reason, especially hydrodynamic load high energy region be located at gate structure low-frequency range cause low resistance mesomerism this is heavy
Feature is wanted, and then by the dynamic characteristic of optimization gate structure, makes the low frequency range of gate structure far from the high energy region of hydrodynamic load,
The important channel for having become control and gate harmfulness being avoided to vibrate.But above-mentioned measure is strong both for avoiding gate from generating
Taken measure is vibrated, when gate is contacted with dynamic water, gate always will appear vibration.Therefore, it needs to design a kind of new skill
Art scheme solves the technical problems existing in the prior art with comprehensive.
