When the present invention works, when after the change of upland water amount, water level is changed, and the water pressure acted on like this on gate also can change thereupon, and gate, under effect of water pressure, can complete the opening and closing process of gate automatically:

First by the oblique vertical shaft of both sides respectively symmetrically device on the gate pier of both sides, and by being rigidly connected between anchor structure and gate pier, again by upper, lower double-deck opposite opened gate is fixed on the oblique vertical shaft of both sides respectively symmetrically by bearing or hinge, when upland water amount increases, when before gate, water level is elevated to certain altitude, the upland water moment (moment around oblique vertical shaft) acted on gate is greater than the moment (moment around oblique vertical shaft) that gate deadweight produces, overcome pivoting friction and between gate and gate pier after magneticaction, can first make lower floor two fan side-by-side gate to rotate to current downstream direction around respective oblique vertical shaft respectively, lower floor's side-by-side gate is opened automatically, and by between gate and gate, the cross-section of river between gate and gate floor sluices to downstream, now, upper strata side-by-side gate keeps motionless, when upland water amount maintain a certain amount of no longer change time, lower floor's side-by-side gate letdown flow is equal with upland water amount, and before gate, water level keeps stable, and gatage keeps stablizing, if upland water amount increases further, when before gate, water level is elevated to certain altitude, effect of water pressure is greater than the moment of gate deadweight and magnet generation further in the moment of lower floor's side-by-side gate, gate can increase further to the aperture of current downstream direction, letdown flow is increased further, simultaneously, upper strata side-by-side gate is under effect of water pressure, the moment (moment around oblique vertical shaft) that water pressure produces is greater than the moment (moment around oblique vertical shaft) that upper strata side-by-side gate deadweight produces, overcome pivoting friction and between gate and gate pier after magneticaction, also can automatically rotate to current downstream direction around respective oblique vertical shaft, upper strata side-by-side gate also can be opened automatically, during design, the water level that upper strata side-by-side gate is opened automatically, should by local flow characteristics and job requirement, rationally determine (can be that lower floor's side-by-side gate is when being opened to a certain aperture, along with namely the raising top side-by-side gate of upper pond level is opened automatically, also can be after lower floor's side-by-side gate is all opened, upper strata side-by-side gate rises along with water level and automatically opens, namely go up, the opening time of lower two-layer gate, rationally can determine according to the actual conditions of locality).If when upland water amount increase to a certain amount of no longer change time, before gate, water level keeps stable, and gate letdown flow is equal with upland water amount, and the aperture of upper and lower internal layer side-by-side gate keeps stablizing; When upland water amount increases to a certain degree, after water level rises to certain altitude before gate, lower floor's side-by-side gate can all be opened, lower floor's side-by-side gate can be made to rotate nearly 90 ° around oblique vertical shaft to current downstream direction, now, lower floor's side-by-side gate and gate pier close, lower floor's side-by-side gate aperture reaches maximum; When upland water amount increases to a certain degree, after water level rises to certain altitude before gate more further, upper strata side-by-side gate also can all be opened automatically, can make upper strata side-by-side gate also around oblique vertical shaft to current downstream direction rotate nearly 90 °, now, upper strata side-by-side gate and gate pier close, upper strata side-by-side gate aperture reaches maximum, like this, upper and lower two-layer side-by-side gate is all opened, and aperture reaches maximum, the ability of letting out is made down to reach maximum, to complete the needs of flood discharge well.Vibration is produced in the course of the work for preventing gate, between upper and lower two-layer side-by-side gate and gate pier, be provided with the magnet that magnetic pole is identical, rely on upper water pressure and the magneticaction of magnet generation between gate and gate pier, to alleviate the vibration of gate, make gate work more steady.Now, the magnetic force between gate and gate pier also reaches maximum.

When upland water amount reduces, before gate, water level can decline thereupon, the upper water pressure moment acted on the side-by-side gate of upper strata is made to be less than the moment of gate deadweight generation, and under magneticaction, after overcoming pivoting friction, upper strata side-by-side gate can rotate towards the direction of current upstream automatically, then the aperture of gate can reduce automatically, thus reduces letdown flow; If when upland water amount be reduced to a certain amount of no longer change time, then before gate, water level keeps stable, and gate letdown flow is equal with upland water amount, and remains unchanged, and upper strata side-by-side gate aperture keeps stablizing; When upland water amount reduces further, water level declines further, the moment that upper water pressure acts on the side-by-side gate of upper strata reduces further, and under magneticaction, gate is rotated in the automatic direction towards closing further, then the aperture of gate can reduce further automatically, simultaneously, the aperture of lower floor's side-by-side gate also can reduce automatically, thus letdown flow is reduced further; When upland water amount is reduced to a certain degree, when before gate, water level decreasing is to certain altitude, upper strata side-by-side gate can be closed automatically; When upland water reduces further again, when before gate, water level decreasing is to certain altitude, lower floor's side-by-side gate can be closed, automatically to keep retaining state.

When after closing gate, due between each fan brake door, between gate and both sides gate pier, be provided with sealing between gate and gate floor, gate can be kept water-tight, complete retaining task, so that emerging profit uses.

So the work of gate is carry out auto-control by the height of upper pond level completely.Along with the change of upland water amount, gate is automatically opened and is kept certain aperture, automatically to complete the needs that sluice, achieves the automatic control of gate by upland water, achieves unmanned working system, apply in very convenient practice.Meanwhile, owing to being provided with upper and lower two-layer opposite opened gate, open, close flexibly convenient, gate stress condition is more perfect, and condition of letting out under current is more reasonable, and streamflow regime is more stable.
