Description
Technical field
The invention belongs to environmental monitoring technology field, and in particular to a kind of river silt detection device.
Background technology
With the quickening of Development of China's Urbanization, economy is developed rapidly, and population is continuously increased, pollution and the alluvial of urban river
Gradually aggravating.On the one hand, river accepted long term municipal sewage and rainy season wash away, and cause river channel sedimentation, have a strong impact on aquatic
State environment；On the other hand, the unreasonable water intaking in upper river causes river course downstream discharge reduction, under water body exchange and self-purification capacity
Drop, causes pollutant largely to deposit, and forms mud.River channel sedimentation can cause the flood discharge capacity in river course to decline, and increase calamity source,
Most probably cause big flood in flood season torrential rain.Thus, channel cleanout ensures significant for flood passage and water ecological environment.
Domestic and international common sludge measurement method includes exploratory bore-hole sampling, static sounding, radiation detecting, ultrasound at present
Ripple detection etc., their principle and the scope of application is different.Drill hole sampling method not only disturbs mud, and workload it is big,
Desilting that is expensive, not being suitable for large area.Cone Penetration Test measurement accuracy is not high, can not measure the distribution situation of mud.
Though radiation detecting measurement accuracy is higher, there is radiological hazard to staff and detection environment.Ultrasonic listening is by underwater
Impurity effect is larger, and can not measure distribution and the density of mud scum.Due to not having clearly between the mud and water layer of precipitation
Interface, mud detection is so far still without finding an accurate method.
According to《Port engineering geological mapping specification》（JTJ240-97）, river silt has four layers：Mud Layer, stream mud layer, become silted up
Mud layer and muck soil.Mud described in patent application document refers to Mud Layer, stream mud layer and mud.
The content of the invention
The problem of existing for prior art, the technical problems to be solved by the invention are just to provide a kind of river silt and visited
Device is surveyed, the thickness of its energy accurate measurement mud, and to mud disturbance is small, security is good, easy to operation.
The technical problems to be solved by the invention are realized by such technical scheme, it include mud probe,
Drinking-water pipe, metering water pump and photoelectric detector, metering water pump are arranged on drinking-water pipe, on drinking-water pipe water inlet connection mud probe
Portion, drinking-water pipe water side connection photoelectric detector, mud probe include probe cylinder, magnetic valve and water pipe, and magnetic valve is located at
Probe cylinder bottom surface, water pipe are located in the side wall of probe cylinder bottom, and clear water tube opening floats up to few 5 meters, probe cylinder
Bottom surface is provided with the touching switch of control closed electromagnetic valve.
The operation principle of the present invention：Mud probe is put into water, and magnetic valve is opened, as mud pops one's head in, into spy
The water sample of head cylinder is followed successively by clear water and mud, when mud probe touches muck soil, the touching switch of probe cylinder bottom surface
Action, closed electromagnetic valve（Lighted with indicator lamp）；After mud probe stands 1 minute, metering water pump is started working, suction probe
Clear water and mud in cylinder, while the clear water that water pipe is introduced on mud, the water sample that photoelectric detector obtains is sequentially clear
Water-mud-clear water.Photoelectric detector is different according to the water quality flowed through in drinking-water pipe, and absorbance is different, can record to obtain
Absorbance changes over time curve, so as to which the depth of mud be calculated.
The solution have the advantages that：Energy accurate measurement silt depth, small, "dead" harm is disturbed to mud, used
Safety, simple in construction, easily operated measurement.
Brief description of the drawings
The brief description of the drawings of the present invention is as follows：
Fig. 1 is the structural representation of the present invention.
In figure：1. mud is popped one's head in；11. probe cylinder；12. magnetic valve；13. water pipe；14. touching switch；2. drinking-water pipe；
3. measure water pump；4. photoelectric detector；5. cable.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples：
As shown in figure 1, the present invention includes mud probe 1, drinking-water pipe 2, metering water pump 3 and photoelectric detector 4, water is measured
Pump 3 is arranged on drinking-water pipe 2,1 top of the water inlet of drinking-water pipe 2 connection mud probe, the water side of drinking-water pipe 1 connection photoelectric detector
4, mud probe 1 includes probe cylinder 11, magnetic valve 12 and water pipe 13, and magnetic valve 12 is located at the bottom surface of probe cylinder 11, clearly
Water pipe 13 is located in the side wall of the bottom of probe cylinder 11, and the opening of water pipe 13 is floated at least 5 meters, and the bottom surface of probe cylinder 11 is provided with
Control the touching switch 14 of closed electromagnetic valve.
In Fig. 1,1 cable 5 is connected between photoelectric detector 4 and magnetic valve 12, being connected to touching on cable 5 opens
Close 14.
