Flood-preventing water level measuring tape with fully-automatic warning function and production method thereof

Abstract

The invention discloses a flood-preventing water level measuring tape with a fully-automatic warning function and a production method thereof. The flood-preventing water level measuring tape comprises a flood-preventing water level measuring tape device, a water level sensor, a flood early-warning sound source, a power amplifier and a high-tone loudspeaker; and the measuring tape device is characterized by comprising an automatic flood early-warning device, a 220-volt alternating-current power supply is arranged at the left side of a block diagram of the early-warning device; a first water level sensing contact, a second water level sensing contact and a third water level sensing contact are arranged at the right side of the early-warning device in sequence; a first flood early-warning sound source, a second flood early-warning sound source and a third flood early-warning sound source are arranged at the right side of the water level sensing contact; the power amplifier is arranged at the right side of the flood early-warning sound source; the high-tone loudspeaker is arranged at the right side of the power amplifier; the first water level sensing contact, the second water level sensing contact and the third water level sensing contact of the fully automatic flood warning device are connected with a water level sensor shell at the right side of the flood-preventing water level measuring tape device; and the flood-preventing water level measuring tape is economical and practical.

Description

technical field [0001] The invention relates to a full-automatic alarm device and a hydrological measuring device, in particular to the manufacturing field of a flood control water level measuring device used in cities and low-lying areas along rivers. Background technique [0002] In recent years, my country's climate has been abnormal and extreme weather events have been frequent. Serious floods have occurred in the Huaihe River Basin, the upper reaches of the Yangtze River, the upper reaches of the Pearl River, and parts of Northwest and North China. Heavy rain and the floods caused by it are one of the major natural disasters in my country. Heavy rain not only directly leads to flooding, but also causes other disasters. The Yangtze River Basin is an area prone to heavy rain and flood disasters, among which the Lianghu Basin and the Yangtze River Delta are particularly affected by disasters. In 1983, 1988, 1991, 1998, 2005, 2006 and 2007, severe rainstorm and flood disaste...
