Unmanned aerial vehicle-carried simple flood and sediment monitoring equipment system for emergency management

Abstract

The invention belongs to the technical field of water flow velocity measurement, and particularly relates to anunmanned aerial vehicle-carried simple flood and sediment monitoring equipment system for emergency management. The unmanned aerial vehicle-carried simple flood and sediment monitoring equipment system for emergency management is a sphere with a hollow structure, and comprises pits, fixing hooks, a channel, a flow velocity meter and an electromagnet, wherein the pits are uniformly formed in the outer surface of a monitoring device body; the fixing hooks are arranged in the pits and can stretch out and draw back in the radial direction of the monitoring device body, and the fixing hooks are positioned in the pits when retracting and stretches out of the outer surface of the monitoring device body when popping up; the channel penetrates through the sphere center of the monitoring device body and penetrates through the whole sphere; the flow velocity meter is arranged in the channel; and the electromagnet is arranged on the outer surface of the monitoring device body, and the monitoring device body is fixed to the unmanned aerial vehicle strong magnet through the electromagnet. The monitoring device is easy to use, a hydrological observation station does not need to be built temporarily, and flow velocity data can be measured anytime and anywhere.

Description

technical field [0001] The invention belongs to the technical field of measuring water flow velocity, and in particular relates to a simple flood sediment monitoring equipment system for unmanned aerial vehicle portable 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. After the rainfall, the rainwater will be drained randomly along a certain ditches or multiple ditches. If we build triangular weirs in each ditches and set up measuring instruments for measurement, the cost will be too high.

[0002] In the process of harnessing the sandstone area of ​​the Ordos Plateau, for the monitoring of medium-rainfall runoff in river channels or small watersheds, 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 weirs 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 a certain ditches or multiple ditches after the rainfall. If we build triangular weirs in each ditches and set up measuring instruments for measurement, the cost will be too high, and the other On the one hand, for more dangerous places, it is not practical to build triangular weirs or add other measuring instruments

[0003] In addition, urban waterlogging often occurs in summer in southern my country due to heavy rains and floods. During urban waterlogging, 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. The existing portable flowmeter is not suitable for measuring the water flow velocity during sudden waterlogging because it needs to be hand-held or simply fixed. Moreover, for some places that are inconvenient for people to enter, the existing measuring instruments are powerless.
