Description

A kind of movable type is adjustable rainfall simulation device
Technical field
The utility model belongs to environmental chemistry, water and soil conservation field, relates to the native water termination contaminated stream of a kind of movable type analogue means.
Technical background
Soil water termination contaminated stream is meant that contaminated soil is under the souring of precipitation or snow melt, contain multiple pollutant and have the current of silt by what the rainwash process formed, be included in a class of carrying dissolubility or solid pollutant special " sewage " of receiving water body in this process, and the polluted-water that river, lake, reservoir, pond and bay etc. are muddy state and contain a series of native water micro interfaces under other factors are disturbed.Wherein, storm runoff is that native water termination is polluted the major impetus that takes place, and it is principal mode and the carrier that native water termination is polluted that native current lose, and native water termination is to pollute the crucial interface that takes place.
At present, mainly utilize rainfall simulator both at home and abroad, parameters such as the raininess by measuring rainfall, raindrop size cooperate that pollutant kind and content etc. carry out correlative study in the soil erosion amount, runoff rate, runoff on the simulation face of land.But rainfall simulator ubiquity at present commonly used is too simplified or complicated situation too, the former normal mode simulated rainfall that adopts approximate " drip irrigation ", because highly not enough, simulate effect and actual conditions deviation are bigger, and to the control deficiency of condition of raining; The latter is bulky usually, and the combination dismounting is convenient inadequately, and complex structure is with high costs.Therefore, still not having a kind of native water termination contaminated stream analogue means can be used widely under study for action.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, easy to install, move flexibly, condition of raining be easy to control, lower-cost native water termination contaminated stream analogue means.
Movable type of the present utility model is adjustable rainfall simulation device, acidproof water tank is connected with high-pressure hydraulic pump, variable valve, flowmeter, sieve formula rainfall generator successively by aqueduct, and acidproof water tank bottom is provided with freeing port; Acidproof water tank is fixed on the base plate, under the base plate pulley is arranged; Sieve formula rainfall generator is assembled by shower nozzle, multilayer screen cloth, limit rail slideway; Variable slope storage soil box places under the sieve formula rainfall generator, is supported by fixing carrying support, adjustable trestle and standing valve, goes up fluted water intaking hole, overflow groove.
The multilayer screen cloth in the different apertures of conversion, thereby the even distribution of control raindrop size and rainfall.
The storage soil box is regulated the gradient by standing valve, fixing carrying support and adjustable trestle.
Portable test stand has anti-lock brake.
The utility model soil water termination contaminated stream analogue means mainly comprises rainfall simulator and face of land analogue means two parts.Rainfall simulator is sent to sieve formula rainfall generator by high-pressure hydraulic pump with the simulation rainwater of preparing in the acidproof water tank, utilizes flowmeter and variable valve control rainfall amount, utilizes multi-deck screen network control system raindrop size and rainfall homogeneity.
Face of land analogue means adopts variable slope storage soil box, tested soil is filled in the groove, by regulating the domatic gradient simulation different gradient face of land.Circular hole is arranged at the soil box bottom, in order to collect seepage flow.
Compare with existing other devices, the utility model combines large-scale analogue means simple and easy simulation apparatus features, has that cost is low, structure is relative to advantages such as physical and chemical parameter controllability simple, that move flexible, native water termination pollution are good.
The novel preparation of simulation rainwater, the simulated rainfall conditions of having realized of this experiment controlled, soil water termination contaminated stream generates and gathers the semiautomatic control of overall process, be convenient in less space to realize the simulation of native water termination pollution course, and simulate effect and actual effect matching degree are higher.This test novel cost low, be easy to installing/dismounting, the simulated conditions scope is bigger, has higher popularization and application values.

Embodiment
Movable type of the present utility model is adjustable rainfall simulation device, acidproof water tank (1) is connected with high-pressure hydraulic pump (2), variable valve (3), flowmeter (6), sieve formula rainfall generator successively by aqueduct (4), and acidproof water tank bottom is provided with freeing port (17); Acidproof water tank is fixed on the base plate (18), and pulley (15) is arranged under the base plate; Sieve formula rainfall generator is assembled by shower nozzle (5), multilayer screen cloth (7), limit rail slideway (9); Variable slope storage soil box places under the sieve formula rainfall generator, is supported by fixing carrying support (11), adjustable trestle (10) and standing valve (12), goes up fluted water intaking hole (14), overflow groove (13).Portable test stand has anti-lock brake (16).
The utility model is achieved in that injection experiments is with simulating rainwater in acidproof water tank (1), open high-pressure hydraulic pump (2), when opening variable valve (3), the simulation rainwater is sent to shower nozzle (5) along portable test stand pipeline (4), the instant flow of flowmeter (6) display simulation rainwater.Multilayer screen cloth (7) is positioned under the adjustable spray thrower, and the simulation rainwater is after the micropore shower nozzle ejection of adjustable spray thrower, and it is online to fall within multi-deck screen.Rainwater is evenly divided into to falling into variable slope storage soil box (8) behind the uniform raindrop of diameter by the mesh of screen cloth.Change different apertures screen cloth by limit rail slideway (9), the raindrop diameter can correspondingly be regulated, and lands speed by adjusting the Height Adjustable raindrop of screen cloth.
Repeatedly adjust variable valve (3) and change different bore diameter porous screen clothes (7), measure the raindrop diameter and the speed of landing, obtain the raindrop diameter and land the empirical relationship of speed and flow, screen cloth kind, control the reference controlled condition of rainfall parameter during as experiment.
On carry adjustable trestle (10), carry when experiment needs angle, tighten and fixing carrying support (11) between standing valve (12), the soil box angle of inclination promptly is fixed.The soil box range of tilt angles is 0-40 °, can satisfy the gradient scope on the common face of land.Tested soil is filled in the soil box, places under the sieve formula rainfall generator.The simulation rainwater falls into soil box, and raindrop impact soil surface, and along with rainfall amount increases, soil surface forms current gradually, with this water flow simulation soil water termination contaminated stream.Contaminated stream flows out along soil box extension overflow groove (13) along under the soil box slope current, puts a sampling bottle under overflow groove, collects sample.Seepage flow to occur after the topsoil water saturation, seepage flow oozes out by soil box bottom groove water intaking hole (14), puts a sampling bottle under groove water intaking hole, collects seepage flow.
During preparation simulation rainwater, can utilize pulley (15) that device is moved to the place, water source, fixedly anti-lock brake (16) prevents because external force causes moving of casing.Determine the rainwater volume according to acidproof water tank high scale.After experiment finishes, open water tank bottom discharge mouth (17) and will remain the rainwater discharge, and flush box.
