The invention discloses a water level alarm for emergency risk disposal and an alarm method. The water level alarm comprises a protective shell, a battery, an alarm assembly, a contact piece and a foam buoy. A bionic bottom plate is arranged below the protective shell, a hollow area is arranged in the bionic bottom plate, and the hollow area is communicated with the protective shell; a buoy is arranged on the bionic bottom plate, and the contact piece is fixed to the buoy. The alarm assembly comprises a buzzer and a display lamp unit. And the leads are reserved at the tails of the battery andthe display lamp unit. And an umbrella stand-shaped structure similar to the shape of the Wanglian leaf is arranged in the interlayer of the bionic bottom plate. When water enters the protective shellthrough the hollowed-out part on the bionic bottom plate, the foam buoy rises along with the water level; after the water level reaches the set height, the contact head of the wire makes contact withthe contact piece, the buzzer gives an alarm, and the display lamps are sequentially lightened. The problems that an existing movable water level alarm is unstable and prone to shaking in water, theaccuracy of a monitoring result is affected, and rollover is prone to happening when the movable water level alarm is impacted are solved, and the movable water level alarm has high practicability.
本发明公开了一种应急风险处置的水位报警器及报警方法,包括保护壳、电池、报警组件、接触片和泡沫浮标;保护壳下方设有仿生底板,仿生底板内设有镂空区域,镂空区域与保护壳连通;仿生底板上放置有浮标,浮标上固定有接触片;报警组件包括蜂鸣器和显示灯单元;电池和显示灯单元尾部留有导线。仿生底板夹层内有和王连叶形状相似的伞架状结构。当有水通过仿生底板上的镂空部分进入保护壳内,泡沫浮标随水位上涨,水位达到设定高度后,导线的接触头与接触片接触,蜂鸣器发出警报,显示灯依次点亮。本发明解决了现有的移动式水位报警器不稳定,在水中易摇晃,影响监测结果的准确性,受冲击易发生侧翻的问题,具有较强的实用性。
