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 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 opposite opened gate is fixed on the inclined shaft of both sides by bearing or hinge, when upland water amount increases, when before gate, water level is elevated to certain altitude, upland water acts on the moment around inclined shaft on gate, be greater than the moment around inclined shaft that gate is conducted oneself with dignity and spring draft force is produced by connecting rod, after overcoming rotation friction, gate can be made to rotate to current downstream direction around inclined shaft, gate is opened automatically, and by between gate and gate pier, the cross-section of river between gate and gate floor sluices to downstream,
Now, gate has certain aperture, due to the effect of connecting rod, makes slide block in slide rail, and slide along the direction to downstream, stiff spring is subject to certain pulling force, and stiff spring is tightened up certain degree, serves the effect 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, upper water pressure acts on the moment around inclined shaft of gate, be greater than the moment around inclined shaft that gate is conducted oneself with dignity and spring draft force is produced by connecting rod, gate can increase further to the aperture of current downstream direction, letdown flow is increased further, stiff spring is strained further, if when upland water amount increase to a certain amount of no longer change time, before gate, water level keeps stable, gate letdown flow is equal with upland water amount, and the aperture of gate keeps stable;
After when coming that the water yield increases to a certain degree, before gate, water level rises to certain altitude, gate can all be opened, gate can be made to rotate nearly 90 ° around inclined shaft to current downstream direction, gate and gate pier close, gatage reaches maximum, the ability of letting out is increased further, to complete the needs of flood discharge well; Now, the pulling force that stiff spring is subject to 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, upper water pressure is made to act on the moment around inclined shaft on gate, be less than the moment around inclined shaft that gate is conducted oneself with dignity and spring draft force is produced by connecting rod, after overcoming pivoting friction, 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 gatage keeps stablizing;
When upland water amount reduces further, water level declines further, upper water pressure acts on the moment around inclined shaft on gate, be less than the moment around 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, thus letdown flow is reduced further; When upland water amount is reduced to a certain degree, before gate, water level decreasing is to certain altitude, the moment around inclined shaft that gate deadweight, spring draft force are produced by connecting rod, be greater than upper water pressure and act on the moment around inclined shaft on gate, gate is closed automatically, to keep retaining state, now, the pulling force of stiff spring is reduced to minimum.
When after closing gate, due between two fan brake doors, be provided with sealing between gate and both sides gate pier and between gate and gate floor, gate can be kept water-tight.The retaining of gate upstream can be retained preferably, 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 two symmetrical fan brake doors, under upland water effect, can opening symmetrically or close, make lower sluicing stream mode symmetrical, more stable than the oblique vertical shaft type hydraulic self-control gate current of single open-door, discharging capacity be stronger.
Innovation of the present invention is to add connecting rod, slide block and stiff spring on the basis of clino-axis type hydraulic self-control gate in the past, due to the interaction of three, make gate be in a stress balance state, the effect alleviating radial gate vibration can be played well, and gate is stressed less.
