Description
Technical field
The present invention relates to environmental monitoring technology fields, are more particularly to the sampling of multi-parameter rainwash and measuring device.
Background technique
Rainwash carries a large amount of silt and pollutant, is the important carrier of the soil erosion and pollution of area source.Over the ground
Table runoff and sediment and pollutant carry out real-time monitoring, are the important means for studying soil erosion regular and pollution of area source process.Mesh
Before, it is time-consuming and laborious to the method that the monitoring of pollutant in runoff mainly takes artificial sample and lab analysis to combine, and
The problems such as there may be pollution and omissions during sample saves.Since rainfall has uncertainty, and sediment content in runoff
There is the feature with rainfall duration and intensity real-time change with pollutant concentration, therefore, traditional sampling and measurement method cannot
Meet the measurement demand of rainwash.
Liquid level sensor and sediment content sensor have more been generally applicable in rainwash monitoring, such as triangle
Weir slope surface cell runoff rate measuring system (CN201110249797) and slotting formula rainwash measurement device living and system
(CN201220030903), the on-line monitoring of run-off and sediment content is realized, but pollutant index is current in rainwash
Still use laboratory measurement.With the development of sensor technology, COD, ammonia nitrogen, nitrate nitrogen, dissolved oxygen, salinity, also than conductance, oxidation
The water quality indicators such as former current potential, turbidity and pH also can realize real-time measurement by corresponding sensor, and be widely used in earth's surface
The water quality monitoring of water body (such as river, reservoir and lake).Common online monitoring instruments such as YSI ProPlus multi-parameter water quality
Tester and HACHHydrolab multiparameter water quality analyzer etc..
For the uncertainty of rainfall time of origin, flow path surface and its pollutional load change in time and space are big the features such as, have
Necessity and sufficiency utilizes existing on-line monitoring technique, designs a kind of sampling apparatus and measuring system suitable for rainwash, real
Existing runoff multi-parameter synchronization, real-time monitoring.
Summary of the invention
The object of the present invention is to provide the sampling of multi-parameter rainwash and measuring device, the device combination rainwashes
Feature and existing sensor technology, can real-time monitoring rainwash major pollutants index, for pollution of area source research basis is provided
Data, and formulate water environment protection Best Management Practices for specific aim and scientific basis is provided.
In order to achieve the above object, the present invention adopts the following technical scheme:
Multi-parameter rainwash sampling and measuring device by funnel, sampler chamber, multi-parameter sensor, data processor and on
Position machine composition；Funnel top periphery is provided with tap hole, and the exit of funnel is flow concentration hole, one end company of flow concentration hole and sampler chamber
Logical, sampler chamber is water collector, and sampler chamber and flow concentration hole connectivity part top 2/3 are equipped with baffle, and lower part 1/3 is water passage, sampling
The room other end is water outlet, and water outlet bottom is equipped with baffle, and height of baffle plate is the 1/2 of sampler chamber height, multi-parameter sensor
Each sensor is placed horizontally at sampler chamber 1/2 and highly locates, and each sensor is connect with data processor respectively, data processor with
Host computer connection.
Advantages of the present invention:
Since the uncertainty of rainfall time of origin often leads to that runoff sample cannot be acquired in time, or due to bad weather
Artificial sample is caused to can not be successfully progress, the automatic sampling and reality that the present invention solves the above problem, realizes Runoff contaminants
When monitor.Since water outlet is arc, so that sampler chamber had not only had the function of certain backwater, but also sediment siltation can be prevented, and there is no harm in
Hinder the mixing and outflow of runoff.

Fig. 1 is the structural schematic diagram of the sampling of multi-parameter rainwash and measuring device.
Wherein: 1 is funnel, and 11 be tap hole, and 12 be flow concentration hole, and 2 be sampler chamber, and 21 be water passage, and 22 be water outlet,
3 be multi-parameter sensor, and 4 be data processor, and 5 be host computer.
Fig. 2 is schematic diagram of the multi-parameter sensor in sampler chamber.
Fig. 3 is the side view of the sampling of multi-parameter rainwash and measuring device.
Specific embodiment
Below in conjunction with attached drawing, the present invention is further illustrated:
The sampling of multi-parameter rainwash and measuring device, the device is by funnel 1, sampler chamber 2, multi-parameter sensor 3, data
Processor 4 and host computer 5 form；1 top periphery of funnel is provided with tap hole 11, and the exit of funnel 1 is flow concentration hole 12, flow concentration hole
12 are connected to one end of sampler chamber 2, and sampler chamber 2 is water collector, and sampler chamber 2 and 12 connectivity part top 2/3 of flow concentration hole are equipped with baffle,
Lower part 1/3 is water passage 21, and 2 other end of sampler chamber is water outlet 22, and 22 bottom of water outlet is equipped with baffle, and height of baffle plate is to adopt
The 1/2 of specimen chamber height, each sensor of multi-parameter sensor 3 are placed horizontally at sampler chamber 1/2 and highly locate, each sensor difference
It is connect with data processor 4, data processor 4 is connect with host computer 5.
Above-mentioned 22 baffle of water outlet is arc.
Above-mentioned multi-parameter sensor selectively using can measure COD, ammonia nitrogen, nitrate nitrogen, dissolved oxygen, salinity, than conductance, oxidation
The sensor of the indexs such as reduction potential, turbidity and pH.
Multi-parameter rainwash is sampled when measuring rainwash and measuring device is placed in runoff plots card by the present invention
Mouth or surface runoff river outlet, so that runoff imports funnel 1.When run-off is smaller, collected, by flow concentration hole 12 through water passage
21 import sampler chamber 2, and runoff mixes in sampler chamber 2；It works required minimum runoff when 2 runoff of sampler chamber reaches sensor 3
When amount requires, data processor 4 sends instruction, and sensor 3 starts to work and acquisition signal is transferred to data processor 4, number
According to being transferred to host computer 5 after data processor 4 reads and calculates；Diameter after measurement flows through the outflow of water outlet 22.Work as run-off
When larger, the tap hole 12 that extra diameter flows through funnel 1 flows out, so that conjunction needed for remaining sensor monitoring in sampler chamber 2
Suitable run-off.
