The vibration of door.During closing gate, between gate and roller groove bottom surface, both sides and gate and gate floor it
Between be provided with sealing, produce drainage during to prevent closing gate.
The vertical height of gate, floating shifting distance upwards, by the water water level of upstream, the reserve-water-level of needs
And the parameter such as gate floor elevation, maximum bleeder quantity, it is calculated analytically and determines.When upper pond level is less than a certain
During water level, the buoyancy that the deadweight of gate is subject to more than gate, at gate in off position；When on upper pond level
When being raised to a certain water level, the buoyancy that gate is subject to is conducted oneself with dignity more than gate, after overcoming frictional resistance, makes
Gate produces and floats, and meanwhile, under the lateral effect of water pressure in upstream, gate can move obliquely upward along track
Dynamic, current will be let out downstream from the aperture between gate bottom panel and gate floor, is automatically performed sluicing and appoints
Business；Now, gate is under buoyancy of water and lateral effect of water pressure, and gate " is floated " in orbit,
Being in poised state, gate top panel remains that the discrepancy in elevation certain between water level is constant.
When the present invention works, after upland water amount changes, make water level to change, do so use
Buoyancy on gate and lateral water pressure also can change therewith, gate under buoyancy and lateral effect of water pressure,
The opening and closing process of gate can be automatically performed automatically along moving on track or declining:
When upland water amount increases, and when before gate, water level is increased to certain altitude, upland water acts on gate
On buoyancy and lateral water pressure also can increase, when the component in orbital direction of making a concerted effort of two kinds of power is more than lock
Door deadweight, when the component of orbital direction and roller shaft internal friction, can make roller produce and rotate, thus drive
Gate moves obliquely upward along orbital direction, and gate automatically opens up, and by gate bottom panel and gate floor
Between drainage gallery downstream sluice；When upland water amount maintain a certain amount of no longer change time, water source, upstream
Water level is constant, and position of strobe is constant, then gate letdown flow is constant, and equal with upland water amount, so,
Before gate, water level keeps stable, and gate is in poised state, and gatage keeps constant；If upland water
Amount increases further, then before gate, water level raises further, at buoyancy and the lateral hydraulic pressure of upland water
Under power effect, gate then can the most automatically raise along track, makes letdown flow increase further,
If when upland water amount increase to a certain amount of no longer change time, before gate, water level keeps stable, earial drainage under gate
Measure equal with upland water amount, then gate can be in again poised state, and the aperture of gate can keep again stable；
When coming after the water yield increases to a certain degree, water level rises to certain altitude before gate, gate can be fully open,
Now, gatage reaches maximum, makes down the ability of letting out reach to increase, to complete the needs of flood discharge well；
The maximum opening of gate, is determined by upland water specificity analysis.
When upland water amount reduces, before gate, water level can decline therewith so that the buoyancy that gate is subject to reduces,
Gate under Gravitative Loads, make roller produce roll, gate moves down therewith so that gate automatically towards
Closedown direction is moved, then the aperture of gate can reduce automatically, thus reduces letdown flow；If working as upland water
Amount is reduced to a certain amount of when no longer changing, then before gate, water level keeps stable, and gate letdown flow comes with upstream
The water yield is equal, and keeps constant, then gate can be in again poised state, and the aperture of gate keeps stable；When
When upland water amount reduces further, water level declines further so that gate is further automatically towards closedown
Direction is moved, then the aperture of gate can reduce the most automatically, so that letdown flow reduces further；When
Upland water amount is reduced to a certain degree, and when before gate, water level decreasing is to certain altitude, gate is at Gravitative Loads
Under be automatically switched off, to keep water-retention state.If upland water amount increases again, then gate can automatically turn on again,
Under let out the unnecessary water yield, if water reduce, gate can be automatically switched off again, go round and begin again, and circulation is carried out.
When after closing gate, due between gate bottom panel and roller groove bottom surface, between gate and gate floor
It is provided with sealing, can effectively carry out leak-stopping, prevent the generation of drainage, reach the requirement of water-retention, with
It is easy to emerging profit use.
Produce vibration for preventing gate in the course of the work along with up-stream face wave, gate and gate pier it
Between be provided with hydraulic shock-absorbing device in roller groove, the vibration of gate can be slowed down, make gate work more steady.
So, the work of float-moving type self-shooter is entirely and is carried out instant auto-control by the height of upper pond level.
Along with the change of upland water amount, gate automatically turns on, closes, and sluices and the needs of water-retention to be automatically performed,
Achieving the unattended working method of gate, popularization and application in convenient practice, this is the revolutionary character to gate
Reform.
