A buoy for river sediment monitoring in flood season

Abstract

The present invention relates to the field of sediment monitoring equipment, in particular to a buoy for river sediment monitoring in the flood season, comprising: a marker body, the marker body is a hollow structure, including a cylindrical part at the upper end and a circular platform part at the lower end; the cylindrical part and the The round platform is connected; inside the standard body, a first partition and a second partition are arranged at intervals along the vertical direction; a number of counterweight adjustment mechanisms are arranged in an array on the first partition; a circular array is arranged on the second partition There are several trigger mechanisms; the floating ring, the floating ring is set outside the target body, and the inside is filled with gas to provide buoyancy for the target body; the balance device; connecting the floating ring and the target body, including: connecting the ring, connecting the bearing, Connect the round shaft; sand measuring sensor; the sand measuring sensor is set at the bottom of the marker body; the GPS module is set inside the marker body; the battery is set inside the marker body, and the trigger mechanism, counterweight adjustment mechanism, GPS module, and sand measurement The sensor is electrically connected.

Description

technical field [0001] The invention relates to the field of sediment monitoring equipment, in particular to a buoy for river sediment monitoring in flood seasons. Background technique [0002] The sediment concentration of rivers changes with time. The maximum sediment concentration in a year is in the flood season, and the minimum sediment concentration is in the dry season; The sediment content of the river is very necessary, because in the flood season, due to the influence of rainfall and other factors that increase the water volume, the sediment content of the river is high. By measuring the sediment content of the river, the upstream water and soil loss can be calculated and estimated, and the downstream The unit plays an information early warning to prevent flood disasters caused by factors such as sediment deposition, river bed elevation, and river water level rise. [0003] There are three common river sediment measurement methods, fixed type, buoy type, and float...

AI Technical Summary

Problems solved by technology

[0003] There are three common river sediment measurement methods, fixed type, buoy type, and floating boat type; the fixed type is to fix the sand measurement sensor on the shore, this method can only measure the sediment content of the near-shore point in the river channel, for the flood season water flow When the speed of change is large, the requirements for point selection are high, and the information obtained is not comprehensive; the basic cost of the pontoon type is high, and the volume is large, and there are certain requirements for the depth and width of the river channel; therefore, the buoy type is due to The cost is low and the measurement results are good. It is the best choice for measuring the sediment concentration of the river during the flood season. The existing buoy has a simple structure. The buoy is prone to tipping when it encounters turbulent water flow or is entangled and hits debris. Therefore, it is necessary to design a new type of buoy to cope with the water potential of the river during the flood season.
