Specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that described herein
Specific embodiment be only used to explain the present invention, be not intended to limit the present invention.
As depicted in figs. 1 and 2, a kind of gate Vertical Vibration Reduction and root edge adjustable systems, including gate, rubber pouch, fill
Airway, inflator pump, pressure valve, electro-magnetic feedback system and cell, gate is by the idler wheel 1 of two sides in slideway in the present embodiment
Slide up and down, cell 2 is set to 5 lower part of bottom beam of gate, and cell 2 is fixedly connected with bottom beam 5 by vibration absorber, cell 2 with
Bottom beam 5 is that the connecting rod 15 stretched out by 11 both ends of vibration absorber and connecting rod 16 connect, and rectangle cell 2 is in four Angle Positions
Vibration absorber 11 is connected, sees Fig. 5 and Fig. 6.Rubber pouch 3 is fixed on inside cell 2 by bolt 9, and the width of cell is less than lock
Gate-width degree, superstructure 10 is provided with above gate door body, includes that inflator pump 6, pressure valve 8 and electromagnetism are anti-in superstructure 10
One end of feedback system 7, inflating catheter 4 is connect with inflator pump 6, and the other end passes through bottom beam 5 and cell 2 is connect with rubber pouch 3, is filled
Airway 4 is made of metal.Electro-magnetic feedback system 7 and pressure valve 8 are set in turn on inflating catheter 4, see Fig. 4.The bottom of gate
Beam 5 is equipped with the hole passed through for inflating catheter 4；It is corresponding on cell and rubber pouch to be equipped with connecting hole.
Gas pressure intensity, which actually reflects, in rubber pouch acts on gate root edge vertically hydrodynamic size, passes through pressure
The dial reading of valve, available vertical hydrodynamic load in real time, by Load Effects, pressure valve, the same electro-magnetic feedback of inflator pump
Interconnection gets up, and the working condition between electro-magnetic feedback system direct regulation and control pressure valve and inflator pump the two opens different
Operating condition is closed, parameter is inputted by electro-magnetic feedback system, changes gas pressure intensity in rubber pouch.Rubber internal gas pressure and lockage
In rubber pouch stable deformation occurs for both pulsating loads of water flow collective effect, changes gate root edge pattern, passes through
Damping on the compressibility increase gate of gas is vertical, reaches the target for reducing gate vertical vibration.
In view of the percussion of gate lower part water flow, which is used to reduce the vertical vibration of gate, regulating gate bottom
Hydrodynamic(al) force value at edge guarantees that lockage flow-shape is stablized, avoids the generation of some unfavorable operating conditions during gate opening/closing.Gate
Service condition is broadly divided into three classes: gate office opens, gate opening and closing gate, above three state correspond respectively to Fig. 3-1,
Operating condition shown in 3-2,3-3, then the working principle of regulator control system is described respectively by above-mentioned three kinds of operating conditions.
1. gate office opens
Under conditions of not changing upstream and downstream sealing form, cell is disposed below in bottom beam, rubber pouch is laid, by changing
Become contacting between pressure valve and inflator pump in superstructure, change the pressure in rubber pouch, and then change root edge form,
The hydrodynamism of lockage water flow changes the pressure distribution form near former gate structure root edge simultaneously, while rubber pouch can
To adapt to the deformation because of pressure change bring regional area, the root edge pattern of gate is made to reach adjustable effect.Make simultaneously
For the vertical active force of rubber pouch, the volume of rubber pouch is changed, makes gas compression in rubber pouch, increases gate
Vibration damping on vertical plays the effect for reducing gate vertical vibration.
Gate opening
Gate opening is mainly focused on contribution of the vertical hydrodynamic force to Qi Menli, capacity needed for reducing headstock gear.Opening and closing
Machine is to connect to open and close with regulating gate with gate by screw rod, and headstock gear is arranged in computer room, has various electromechanics to set in computer room
It is standby, such as headstock gear, power distribution cabinet, workshop, duty room.In the whole process of gate opening, before not moving, pass through inflator pump
Rubber pouch is inflated, increases rubber bag tank bag body product, buoyancy suffered by gate door body is increased, so that gate is no longer
In full off state, there is minimum vertical deviation in gate, with traditional gate opening process, headstock gear when gate can be avoided to start
There is moment maximum value.In opening process, water pressure suffered by gate root edge reduces the pressure for passing through inflator pump augmented airbag in addition
By force, so that the tensile stress of pull rod or strand cable reduces, the fatigue effects such as headstock gear possesses the safe clearance of abundance, and alleviates pull rod
It answers.The elastic characteristic of air bag can be good at guaranteeing that water flow has smoothly stable stream feature out under lock.
Closing gate
Closing gate process then focuses on increasing the lower suction effect in the hydrodynamic force of gate root edge, reduces headstock gear pair with this
Pressure on screw rod prevents the appearance of pressure bar stabilization problem, for emergency gate.It is put by opening pressure valve
Portion gas out reduces the gas pressure intensity in rubber pouch, so that " recessed " is presented in cell region, water flow deflection is obvious, increases
Negative pressuren zone near gate root edge keeps suction effect under gate significant, the trend of increase gate falling motion.While rubber pouch
Elastic reaction also can stationary flow, avoid occurring bad fluidised form under lock.
In above-mentioned three kinds of operating conditions, load effect, which makes it possible to rubber pouch, to deform in time, rubber occur
Pouch and cell body vibration, and this partial vibration energy is undertaken by the vibration absorber 11 between cell and bottom beam.Vibration damping dress
It sets and sees Fig. 7, the spring 13 in cell vibrocompression vibration absorber, spring 13 drives balance briquetting 14 to generate vibration, damper 12
Coupling linkage is generated with balance briquetting 14, and carries out the effect of consumption vibrational energy by damper 12.The arrangement of vibration absorber
It is the supplement to rubber pouch energy-eliminating shock-absorbing, realizes the dual guarantee to gate energy-eliminating shock-absorbing.
The present invention is not limited to embodiments described above.Above the description of specific embodiment is intended to describe and say
Bright technical solution of the present invention, the above mentioned embodiment is only schematical, is not restrictive.This is not being departed from
In the case of invention objective and scope of the claimed protection, those skilled in the art may be used also under the inspiration of the present invention
The specific transformation of many forms is made, within these are all belonged to the scope of protection of the present invention.
