When upper pond level declines by higher level, gate, under the tractive force effect of spring, is delivered on gate by connecting rod, can reduce gatage in time better, controls letdown flow size better.The spring draft force that connecting rod and stiff spring produce, add water pressure and deadweight that gate is subject to, the interaction between them, makes gate be in a stress balance state, can play the effect alleviating radial gate vibration well.

So the Main Function of vibration damping draw-gear is: the first, can vibration effectively in the regulating gate course of work.The second, solve the moment around space inclined axis produced when gatage is comparatively large, make gate conduct oneself with dignity less, can not the timely problem automatically reducing aperture with water level decreasing better.

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, gate, under water pressure, gate deadweight and spring draft force acting in conjunction, can complete the opening and closing process of gate automatically:

First by the space inclined 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 space inclined 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 space inclined shaft) acted on gate is greater than the moment around space inclined shaft that gate is conducted oneself with dignity and spring draft force is produced by connecting rod, after overcoming rotation friction effect, can first make lower floor two fan side-by-side gate to rotate around the axial current downstream direction of respective Space Oblique 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 in the moment of lower floor's side-by-side gate the moment around space inclined shaft that gate is conducted oneself with dignity and spring draft force is produced by connecting rod further, lower floor's side-by-side 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 space inclined shaft) that water pressure produces is greater than the moment around space inclined shaft that upper strata side-by-side gate is conducted oneself with dignity and spring draft force is produced by connecting rod, after overcoming pivoting friction, also can automatically rotate around the axial current downstream direction of respective Space Oblique, 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, can make lower floor's side-by-side gate around about Space Oblique axial current downstream direction half-twist, 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, upper strata side-by-side gate can be made also around about respective Space Oblique axial current downstream direction half-twist, 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.

Space Oblique shaft design ensure that gate is when different opening, the moment of closing the door that the active force of gate weight and spring produces can be enough to closing gate, solve clino-axis type hydraulic self-control gate aperture larger time, the moment of closing gate that makes that gate deadweight produces reduces, and is unfavorable for the problem of the closedown of gate; The design of gate pier face pinch plane makes streamflow regime in lock chamber stablize; When closing gate, the extruding force produced between every layer of side-by-side gate due to double-deck opposite opened gate, can make gate more stable; Gate can adopt plane gate, and has suitable weight, and the weight of gate, depending on upstream depth of water size, to ensure, under the effect of water pressure of upstream, freely to open, close, and ensures that safe operation is principle; Between two fan brake doors, gate and both sides gate pier and be provided with sealing between gate and gate floor, leak to prevent from producing during closing gate;

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 vibration damping draw-gear, when gate has certain aperture, due to the effect of connecting rod, make slide block in slide rail, slide along the direction to downstream, stiff spring is subject to certain pulling force, and stiff spring is tightened up certain degree, serve damping effect, and complete the process of energy storage; When upland water amount maintain a certain amount of no longer change time, 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, then before gate, water level raises further, and gate can increase further to the aperture of current downstream direction, letdown flow is increased further, stiff spring is strained further, and when gatage reaches maximum, stiff spring energy storage reaches maximum; Gate, under water pressure, gate deadweight and spring force acting in conjunction, can alleviate the vibration of gate well, make gate work more steady.

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 around space inclined shaft that gate is conducted oneself with dignity and spring draft force is produced by connecting rod, 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, upper water pressure acts on the moment around space inclined shaft on gate, be less than the moment around space inclined shaft that gate is conducted oneself with dignity and spring draft force is produced by connecting rod further, 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.
