Ecological desilting diffusion measuring device

Abstract

The invention relates to an ecological desilting diffusion measuring device which is characterized by comprising a sensor bracket and a control system, wherein a concentration meter, a height meter and a liquid level meter are arranged on the sensor bracket and are connected with the control system through leads respectively; the sensor bracket is arranged at the front end of a pipe frame; the pipe frame is arranged at the upper end of an adjusting bracket; and the pipe frame is L-shaped and consists of a plurality of pipe sleeves and a bent joint. The ecological desilting diffusion measuringdevice has a simple structure and low manufacturing cost; all the members can be disassembled and assembled quickly and are convenient to carry, install and use, and the diffusion condition of sediments or suspended substances around a desilting tool bit in a desilting process can be measured to judge whether the desilting tool bit is an environmentally-friendly desilting tool bit; and the diffusion condition of sludge around the working desilting tool bit is measured in real time during desilting operation, so that data are provided for adjusting the working state of the desilting tool bit, the diffusion distance of sediments or suspended substances is shortened, the requirement of ecological desilting is met, and ecological desilting is realized.

Description

technical field [0001] The invention relates to a measuring device, in particular to an ecological dredging diffusion measuring device, which is used for measuring the diffusion of sediment or suspended matter during ecological dredging operations. Background technique [0002] There are many rivers, lakes and reservoirs in China, but due to the lack of awareness of environmental protection for many years, industrial waste, urban and rural domestic sewage, and residues of chemical fertilizers and pesticides in agricultural production are directly discharged into lakes and rivers with little or no treatment, resulting in serious water pollution. The content of heavy metals, eutrophication and other harmful chemicals far exceeds the allowable value, which poses a great threat to the urban environment and people's life and health. Relevant data show that the seven major water systems in my country are all polluted to varying degrees, among which the Liaohe River, Haihe River, a...

Problems solved by technology

At present, the judgment of the ecological dredging cutter head and whether it is an ecological dredging operation mainly depends on observing the diffusion of sediment or suspended matter during dredging. The diffusion of sediment or suspended matter is mainly determined by observing the turbidity of the water body during dredging. In order to determine whether the dredging cutter head and the dredging operation are environmentally friendly, it is impossible to scientifically judge whether the dredging cutter head used for ecological dredging is an environmentally friendly dredging cutter head

Diffusion during dredging is mainly observed with human eyes or underwater cameras: human eyes can only observe a very shallow area above and below the water surface, and the observation distance of underwater cameras is greatly affected by water quality, so it is difficult to observe through images Diffusion situation, basically unusable in actual work

The observation method can only give the partial diffusion of sediment or suspended matter during dredging by feeling, and cannot reflect the actual diffusion scientifically and comprehensively. Therefore, an ecological dredging measurement device is needed, which can measure the sediment or suspended solids conveniently and in real time. The diffusion of the surrounding sediment or suspended matter when the dredging cutter head is working, so that it can scientifically and accurately determine whether the dredging cutter head is an environmentally friendly dredging cutter head
