Description
Technical field
The utility model relates to the small hydraulic project equipment technical field of water and soil conservation, is specifically related to a kind of low interference slope runoff sampling thief that is mainly used in the test of monitoring soil and water loss and non-point pollution thing migration under natural precipitation and the artificially-simulated rainfall condition.
Background technology
Silt content in the slope runoff is to estimate the important parameter of soil erosion, and is most important for bringing soil erosion under control to the mensuration of silt content in the runoff.Simultaneously, many quilts are opened up wasteland into the farmland in the lowland of part mountain stream both sides, and current can carry nutrients such as nitrogen, phosphorus and enter into the river course in the runoff process, become the important source that produces non-point pollution, finally can influence the water quality at water source.In to silt content and runoff, all need diameter stream to sample before the measurement of non-point pollution thing content, the precision of sampling directly influences the precision of measurement result.
The method of sampling of existing rainwash mainly is to set up runoff plots, builds the water [proof of being made up of reinforced concrete structure and antiseepage cloth around the sub-district, places part flow arrangement and surveys bucket at the water delivering orifice of runoff plots, belongs to lump type and measures.This acquisition method operational management is convenient, can accomplish the mensuration of the soil erosion amount that produces in the runoff plots in precipitation process, is suitable for long-term position monitor.
The runoff plots method of sampling is convenient to control test condition, repeatedly carries out repetition.But there is following defective in the method:
1, there be the problem bigger to environmental disturbances in the runoff plots method of sampling, and runoff plots belongs to permanent installation, is difficult to after building up restore to the original state.In the runoff plots work progress; Topsoil around inevitably will destroying, vegetation etc., to such an extent as to influence runoff, so construction must restore to the original state surrounding soil after finishing; And the recovery of vegetation often needs 1 year even longer time, and what influence was tested carries out.
2, a runoff plots has only an outlet usually; Be difficult to the migration of runoff plots inside non-point pollution thing is monitored; Understand runoff if desired and flow through the quantity of sand and mud that carries after the different distance and the variation of non-point pollution thing content; Must set up a plurality of runoff plots of different length, waste time and energy.
For these reasons, design a kind of simple in structurely, practical, can not change, destroy environment, measure accurately, time saving and energy saving low interference slope runoff sampling thief is problems of needing solution badly of those skilled in the art.
The utility model content
To the defective that above-mentioned prior art exists, the purpose of the utility model provides a kind of low interference slope runoff sampling thief.
The technical scheme of the utility model is: a kind of low interference slope runoff sampling thief; Comprise water leg, tank and the connecting pipe that connects the two, said water leg comprises circular arc cell body and groove lid, and said groove lid is installed in the top of cell body one circular arc side channel wall; The top of another circular arc side channel wall of said cell body outwards and be tilted to and extend to form the diversion tongue; It is fashionable that said groove lid closes, and forms the water inlet of water leg between the diversion tongued and grooved lid, and osculum is offered in said water leg bottom; The seat that is tightly connected is equipped with in the osculum outside; Being tightly connected is provided with the cavity pipe with connecting pipe UNICOM in the middle of the seat, said connecting pipe and the socket of the cavity seal of tube, and the other end of said connecting pipe is communicated with the inlet opening of tank.
The utility model is characterised in that said groove lid is connected with cell body through rotating shaft, loose-leaf or hinge.
The utility model is characterised in that the outside of two planar side cell walls of said cell body is equipped with fixed orifice, fixed handle or fixed pin.
The utility model is characterised in that between said connecting pipe and the cavity pipe and is connected through the water-tight adhesive tape.
The utility model is characterised in that the inlet opening and the connecting pipe sealing socket of said tank.
Be connected through the water-tight adhesive tape between the inlet opening that the utility model is characterised in that said tank and the connecting pipe.
The utility model is characterised in that said tank comprises rainhat, straight tube and bend pipe; The two ends of said bend pipe are respectively equipped with straight tube; And bend pipe is communicated with straight tube; The rainhat of an activity is stamped on the top of two straight tubes respectively, and the inlet opening is opened in the position of the sidewall of one of them straight tube near the top.
The utility model is characterised in that said water leg adopts plastic-steel, plastics or metal to process.
The utility model provides a kind of low interference rainwash sampling thief that is applicable to scientific research, and its assembling and disassembling is convenient, both can be used for long-term position monitor, also can be used for the interim sampling in a plurality of places; Compare with traditional runoff plots mode, it is very little to the influence of envirment factors such as surface soil, vegetation and rainwash, is highly suitable for the area of easy generation soil erosions such as mountain area; Its volume is little, takes up an area of fewly, and group more than can among a small circle in, laying is used for gathering the runoff sample of the diverse location of survey region, the migration situation of monitoring soil and water loss and non-point pollution thing; Set water leg has loose slot lid, and the closed slots lid prevents that precipitation from directly dropping in the water leg during sampling, guarantees that with closed back of time slot lid and opening between the diversion tongue rainwash can get into water leg, just can open groove when needing the cleaning water leg and cover; Connecting pipe between water leg and the tank is a rubber hose, makes that like this relative position of water leg and tank is more flexible, can do suitable adjustment according to landform; Tank uses three type polypropylene (PP-R) materials, not only firm leakproof but also do not influence water quality, and the tank top end opening is bigger, is convenient to therefrom take a sample.Above characteristic makes this sampling thief be specially adapted to the sample collecting of field test.
Compare with traditional water sample acquisition method; The low interference rainwash sampling thief of the utility model, little to environmental disturbances, assembling and disassembling is convenient; Simple in structure, easy to operate, cheap, be more suitable for being used for the field test of monitoring soil and water loss and non-point pollution thing migration.
