Water level alarm for emergency risk disposal and alarm method

Abstract

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.

Description

technical field [0001] The invention relates to an alarm, in particular to a water level alarm and an alarm method for emergency risk disposal. Background technique [0002] Water level alarm is a device commonly used to monitor water level and issue alarms in landslide dammed lakes, reservoirs and dams. According to whether the device can be moved, water level alarms can be divided into fixed water level alarms and mobile water level alarms. [0003] The fixed water level alarm needs to be fixed at a certain place and cannot move freely, the working area is limited, and the common fixed water level alarm is expensive. However, the existing mobile water level alarms are unstable in the water and are easy to shake with the fluctuations of the water, which affects the accuracy of the monitoring results. . Contents of the invention [0004] Purpose of the invention: The present invention provides a water level alarm and an alarm method for emergency risk disposal to solve t...
