Efficient portable runoff sediment monitoring device system for emergency management

Abstract

The invention belongs to the technical field of water flow velocity measurement, and particularly relates to an efficient portable runoff sediment monitoring device system for emergency management. The efficient portable runoff sediment monitoring device system for emergency management comprises a spherical monitoring device body, wherein the monitoring device body is of a hollow structure, pits are evenly formed in the outer surface of the monitoring device body, fixing hooks capable of stretching out and drawing back in the radial direction of the monitoring device body are arranged in the pits, the fixing hooks are positioned in the pits when contracting, the fixing hooks are positioned on the outer surface of the monitoring device body when popping up, the monitoring device body further comprises a channel penetrating through the center of a sphere and the whole sphere, and a flow meter is arranged in the channel. The efficient portable runoff sediment monitoring device is easy to use, a hydrological observation station does not need to be built temporarily, flow velocity data can be measured anytime and anywhere, and powerful data support is provided for urban emergency management and the like.

Description

technical field [0001] The invention belongs to the technical field of measuring water flow velocity, and in particular relates to a high-efficiency portable runoff sediment monitoring device system for emergency management. Background technique [0002] In the treatment process of the sandstone area in the Ordos Plateau, for the monitoring of medium runoff in the river channel or small watershed, in the prior art, triangular weirs are usually built at the bottom of the ditch, and measuring instruments are installed at the mouth of the triangular weir for measurement. However, due to the small watershed There are many ditches at the bottom of the inner ditches, and the rainwater will be drained randomly along one or more ditches after the rainfall. If a triangular weir is built in each ditch and a measuring instrument is installed for measurement, the cost will be too high.

[0002] In the treatment process of the sandstone area in the Ordos Plateau, for the monitoring of medium runoff in the river channel or small watershed, in the prior art, triangular weirs are usually built at the bottom of the ditch, and measuring instruments are installed at the mouth of the triangular weir for measurement. However, due to the small watershed There are many ditches at the bottom of the inner ditches. After the rainfall, the rainwater will be drained randomly along one or more ditches. If a triangular weir is built in each ditch and a measuring instrument is set up for measurement, the cost will be too high

[0003] In addition, urban waterlogging often occurs in summer in southern my country due to heavy rain and floods. When urban waterlogging occurs, it is necessary to measure the flow rate of water passing through the city, so that the emergency management department can improve or control urban waterlogging. The water flow velocity during waterlogging cannot be accurately measured, and the existing portable current meters are not suitable for measuring the water flow velocity during sudden waterlogging due to the need for hand-held or simple fixation
