Description

technical field [0001] The invention relates to the field of instruments and meters, and in particular provides a hand-held electrician's meter. Background technique [0002] Urban waterlogging refers to the phenomenon of accumulated water disasters in cities due to heavy or continuous precipitation exceeding the urban drainage capacity. The objective cause of waterlogging is the high intensity and concentrated range of rainfall. Where the rainfall is particularly rapid, waterlogging may form, and the rainfall intensity is relatively strong and the time is relatively long. Waterlogging may also form. In some cities in China, the layout of drainage pipes is outdated, the pipelines are aging, and the drainage standards are relatively low; in some places, the drainage facilities are not perfect and imperfect, and the lagging construction of drainage systems is an important reason for waterlogging; in addition, a large number of hard pavements in cities, Such as asphalt roads ...

Problems solved by technology

In some cities in China, the layout of drainage pipes is outdated, the pipelines are aging, and the drainage standards are relatively low; in some places, the drainage facilities are not perfect and imperfect, and the lagging construction of drainage systems is an important reason for waterlogging; in addition, a large number of hard pavements in cities, Such as asphalt roads and cement roads, the water permeability is not good when it rains, it is not easy to infiltrate, and it is easy to form water accumulation on this section of the road

[0003] Whenever summer comes, when many cities face heavy rains, due to the defects of the drainage system, urban waterlogging often occurs. Usually, before the heavy rain comes, the relevant departments will install water level monitors in areas prone to waterlogging to monitor local areas. At present, many water level monitors on the market are installed and fixed on the outer wall of the light pole, which is very inconvenient to install and fix. Moreover, the detection modules of many existing water level monitors are mostly fixed installations. After the water level rises to the installation height , it is easy to cause the detection module to be submerged, which will cause the circuit of the equipment to be damaged by water; therefore, it is urgent to provide a hand-held electrical instrument to solve the above problems
