Abstract

The utility model discloses a sampling of multi -parameter surface runoff and measuring device relates to environment monitoring technology field. The device comprises funnel (1), sampling room (2), multi -parameter sensor (3), data processor (4) and host computer (5). The utility model overcomes since the rainfall time of origin nondeterminacy leaded to can not in time gather the runoff sample, or because problem that the bad weather leads to manual sampling to go on smoothly, realized formulating the automatic sampling and the real -time supervision of runoff pollutant the best management measure of water environment protection for the pertinence and provide the scientific basis.

Description

The sampling of multiparameter rainwash and measurement apparatus
Technical field
This utility model relates to environmental monitoring technology field, is more particularly to the sampling of multiparameter rainwash and measurement apparatus.
Background technology
Rainwash carries substantial amounts of silt and pollutant, is the important carrier of Soil erosion and pollution of area source.Surface flow silt and pollutant are monitored in real time, is the important means of research soil erosion regular dough-making powder source pollution course.At present, the method that the monitoring of pollutant in runoff is mainly taked artificial sample and lab analysis combine, wastes time and energy, and would be likely to occur the problems such as pollution and omission in sample preservation process.Owing to rainfall has uncertainty, and in runoff, sediment charge and pollutant levels have the feature with rainfall duration and intensity real-time change, and therefore, traditional sampling and measuring method can not meet the measurement demand of rainwash.
Liquid level sensor and sediment charge sensor have comparatively been generally applicable in rainwash monitoring, such as slope plot runoff flow measurement system of triangular weir (CN201110249797) and live slotting formula rainwash determinator and system (CN201220030903), achieve the on-line monitoring of run-off and sediment charge, but in rainwash, pollutant index still adopts laboratory measurement at present.Development along with sensor technology, COD, ammonia nitrogen, nitrate nitrogen, dissolved oxygen, salinity, also can pass through corresponding sensor than water quality index such as conductance, oxidation-reduction potential, turbidity and pH and realize measuring in real time, and be widely used in the water quality monitoring in surface water body (such as river, reservoir and lake etc.).Common on-line monitoring instrument such as YSIProPlus multi-parameter water quality tester and HACHHydrolab multiparameter water quality analyzer etc..
For features such as the uncertainty of rainfall time of origin, flow path surface and pollutional load change in time and space thereof are big, it is necessary to make full use of existing on-line monitoring technique, design a kind of sampling apparatus suitable in rainwash and the system of measurement, it is achieved runoff multiparameter synchronizes, monitors in real time.
Summary of the invention
The purpose of this utility model is in that; the sampling of multiparameter rainwash and measurement apparatus are provided; this device is in conjunction with rainwash feature and existing sensor technology; rainwash major pollutants index can be monitored in real time; there is provided basic data for pollution of area source research, and formulate water environment protection kind of Best Management Practices offer scientific basis for specific aim.
In order to achieve the above object, this utility model adopts the following technical scheme that
The sampling of multiparameter rainwash and measurement apparatus are made up of funnel, sampler chamber, multi-parameter sensor, data processor and host computer;Funnel top periphery has tap hole, the exit of funnel is flow concentration hole, flow concentration hole connects with one end of sampler chamber, sampler chamber is water collector, sampler chamber and flow concentration hole connectivity part top 2/3 are provided with baffle plate, bottom 1/3 was aquaporin, the sampler chamber other end is outlet, baffle plate it is provided with bottom outlet, height of baffle plate is the 1/2 of sampler chamber height, each sensor of multi-parameter sensor is all placed horizontally at sampler chamber 1/2 At The Height, and each sensor is connected with data processor respectively, and data processor is connected with host computer.
Above-mentioned outlet baffle plate is arc.
Above-mentioned multi-parameter sensor adopts can measure COD, ammonia nitrogen, nitrate nitrogen, dissolved oxygen, salinity, sensor than conductance, oxidation-reduction potential, turbidity and pH index.
Advantage of the present utility model:
Owing to the uncertainty of rainfall time of origin often leads to gather in time runoff sample, or owing to vile weather causes that artificial sample cannot be smoothed out, this utility model solves the problems referred to above, achieves the sampling automatically of Runoff contaminants and monitor in real time.Owing to outlet is arc so that sampler chamber had both had certain backwater function, Sediment Siltation can be prevented again, and do not interfere with mixing and the outflow of runoff.
Accompanying drawing explanation
Fig. 1 is the structural representation of the sampling of multiparameter rainwash and measurement apparatus.
Wherein: 1 is funnel, 11 is tap hole, and 12 is flow concentration hole, and 2 is sampler chamber, and 21 was aquaporin, and 22 is outlet, and 3 is multi-parameter sensor, and 4 is data processor, and 5 is host computer.
Fig. 2 is multi-parameter sensor schematic diagram in sampler chamber.
Fig. 3 is the side view of the sampling of multiparameter rainwash and measurement apparatus.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described:
The sampling of multiparameter rainwash and measurement apparatus, this device is made up of funnel 1, sampler chamber 2, multi-parameter sensor 3, data processor 4 and host computer 5;Funnel 1 top periphery has tap hole 11, the exit of funnel 1 is flow concentration hole 12, flow concentration hole 12 connects with one end of sampler chamber 2, sampler chamber 2 is water collector, sampler chamber 2 and flow concentration hole 12 connectivity part top 2/3 are provided with baffle plate, bottom 1/3 was aquaporin 21, sampler chamber 2 other end is outlet 22, it is provided with baffle plate bottom outlet 22, height of baffle plate is the 1/2 of sampler chamber height, each sensor of multi-parameter sensor 3 is all placed horizontally at sampler chamber 1/2 At The Height, and each sensor is connected with data processor 4 respectively, and data processor 4 is connected with host computer 5.
Above-mentioned outlet 22 baffle plate is arc.
Above-mentioned multi-parameter sensor selectivity adopts can measure COD, ammonia nitrogen, nitrate nitrogen, dissolved oxygen, salinity, sensor than indexs such as conductance, oxidation-reduction potential, turbidity and pH.
The sampling of multiparameter rainwash and measurement apparatus, when measuring rainwash, are positioned over runoff plots bayonet socket or surface runoff river outlet so that runoff imports funnel 1 by this utility model.When run-off is less, flow concentration hole 12 collecting, import sampler chamber 2 through aquaporin 21, runoff mixes in sampler chamber 2;When sampler chamber 2 runoff reach sensor 3 work required minimum run-off require time, data processor 4 sends instruction, sensor 3 is started working and collection signal is transferred to data processor 4, and data are transferred to host computer 5 after data processor 4 reads and calculates;Footpath after measurement flows through outlet 22 and flows out.When run-off is bigger, unnecessary runoff flows out through the tap hole 12 of funnel 1 so that remain the suitable run-off needed for Sensor monitoring in sampler chamber 2.
