Hydraulic self-control flap gate capable of automatically discharging flood and controlling water level
The invention relates to the technical field of flood control and disaster reduction, and discloses an automatic flood discharge and water level controllable hydraulic self-control flap gate which comprises a gate, a gate side plate, a gate bottom plate, a pawl assembly, a ratchet wheel, a manual control assembly and a manual control switch. The flap gate is unattended, and when the water level in front of the gate is flush with the upper edge of the gate, the gate is in an overturning critical state; when the water level in front of the gate is higher than the upper edge of the gate, hydraulic torque is larger than self-weight torque of the gate, the gate automatically turns over and is opened under the action of water pressure, and the gate begins to discharge water through overflowing; after water drainage reaches a certain time, the water level in front of the gate drops to be lower than the upper edge of the gate, the hydraulic torque is smaller than the self-weight torque of the gate, the gate automatically turns over and is closed under the self-weight effect, and therefore the water level in front of the gate can be controlled to be at the normal water storage level. When the maximum flood discharge needs to be guaranteed, the pawl assembly is controlled through the manual control switch, the gate can only be opened in one direction under the hydraulic action, the gate can only be opened more and more, and therefore the maximum flow discharge is guaranteed.
本发明涉及防洪减灾技术领域，公开了一种自动泄洪及可控水位的水力自控翻板闸，包括：闸门、闸门侧板、闸门底板以及棘爪组件、棘轮、手控组件与手控开关。本发明的翻板闸无需人员值守，当闸前水位与闸门上沿齐平时，闸门处于翻转临界状态；当闸前水位高于闸门上沿时，水力力矩大于闸门的自重力矩，闸门在水压力作用下自动翻转开启，闸门开始过流泄水；当泄水达到一定时间后，闸前水位下降，低于闸门上沿，水力力矩小于闸门的自重力矩，闸门在自重作用下自动翻转关闭，从而可以控制闸前水位在正常蓄水位。当需要保证最大泄洪时，通过手控开关控制棘爪组件，使得闸门只能在水力作用下单向开启，闸门只能越开越大，从而保证最大泄流。
