Abstract

Disclosed are a flood prevention water level measuring ruler with the alarm function and a production method thereof. The flood prevention water level measuring ruler comprises a flood prevention water level measuring ruler device, a water level sensing device, flood situation warning sound sources, a power amplifier and a high tone loudspeaker. The flood prevention water level measuring ruler is characterized by also comprising a flood full-automatic alarm device; the left side of an alarm device block diagram is provided with a 220V alternating current power supply; a first water level sensing contact, a second water level sensing contact and a third water level sensing contact are arranged on the right side of the alarm device block diagram in turn; the right side of the water level sensing contacts is provided with a first flood situation warning sound source, a second flood situation warning sound source and a third flood situation warning sound source; the right side of the flood situation warning sound sources is provided with the power amplifier; the right side of the power amplifier is provided with the high tone loudspeaker; the first water level sensing contact, the second water level sensing contact and the third water level sensing contact which are arranged in the flood full-automatic alarm device are connected with a water level sensing device housing which is arranged on the right side of the flood prevention water level measuring ruler device. The flood prevention water level measuring ruler with the alarm function 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 field of manufacturing a flood control water level gauge for 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 disasters occurred, an...
