Description
Technical field
The present invention relates to a kind of moving analog rainfall apparatus.
Technical background
Basic both at home and abroad at present employing artificially-simulated rainfall machine is simulated natural rainfall, by measuring raindrop kinetic energy, soil erosion amount, study the rule that influences to soil erosion such as its rainfall pattern, landforms and geologic condition, vegetation pattern, edaphic condition, thereby realize dynamic monitoring erosion zone.For the rule of studying soil erosion and realize quantitative forecast to soil erosion, the simulated rainfall machine of suitable field work commonly used has following spray, lateral spray type, combined type etc.Wherein, the confidential field of asking of following spray artificially-simulated rainfall has enough places to set up instrument, and still actual place often can not directly be satisfied, but also needs propulsion system, and therefore poor mobility can not be extensive use of; Lateral spray type simulated rainfall machine adopts the combined shower nozzle of valve control more; The many shower nozzles of lateral spray type valve control combination artificially-simulated rainfall machine needs power output and large-scale transportation equipment, very inconvenience of combination, loading and unloading, and also desire surveys the rainfall of certain rainfall intensity, needs to use the shower nozzle of correspondence.The stream breaker of lateral spray type shower nozzle breaks away from sprinkler body, has increased the complicacy of structure; Many shower nozzle combinations, volume is huge naturally, and inconvenience is carried.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, highly sensitive, easy to install, moving analog rainfall apparatus of being easy to carry, being suitable for field measuring.
Moving analog rainfall apparatus of the present invention, comprising can be airtight and have the water supply installation and a raindrop water storage generator of filler, it is characterized in that water supply installation is fixed in raindrop water storage generator top, described water supply installation is provided with raindrop water storage generator liquid level regulating tube and the filling pipe that stretches into raindrop water storage generator, described liquid level regulating tube is higher than the lower port of filling pipe, and described raindrop water storage generator bottom is provided with the watering duct.
Compared with prior art, the present invention have simple structure, highly sensitive, dismantled and assembled, volume is little, in light weight, the remarkable advantage that waits easy to carry.
Description of drawings
Fig. 1 is the organigram of the embodiment of the invention.
Embodiment
The present invention is achieved in that comprise can be airtight and have the water supply installation 1 and a raindrop water storage generator 2 of filler 3, it is characterized in that water supply installation 1 is fixed in raindrop water storage generator 2 tops, described water supply installation 1 is provided with raindrop water storage generator liquid level regulating tube 4 and the filling pipe 5 that stretches into raindrop water storage generator 2, described liquid level regulating tube 4 is higher than the lower port of filling pipe 5, and described raindrop water storage generator 2 bottoms are provided with watering duct 6.
Wherein, water supply installation 1 is positioned on the dividing plate 7 on the raindrop water storage generator 2; Raindrop water storage generator 2 is socketed on the adjustable lifting support 9 by the arm of being located on the raindrop water storage generator 28, described adjustable lifting support 9 is connected and composed by the sleeve pipe 10 that is socketed on the raindrop water storage generator arm 8, and the threaded hole on described sleeve pipe 10 sidewalls is provided with set screw 11.
When the hillside soil erosion test of carrying out different gradient, can pass through to regulate the height of adjustable elevating lever 9, thereby make raindrop water storage generator 2 keep horizontalitys, so that accurately measure.
Filler 3 on the described water supply installation 1 is provided with the filler pipe road 13 of band variable valve 12; Described raindrop water storage generator liquid level regulating tube 4 is made of the adjustable draw-tube 15 that has variable valve 14, this is adjustable draw-tube 15 is provided with by being threaded upper and lower body.When the user will have externally threaded lower tube body 16 precessions or back-out and have the upper tube body 17 of internal thread, this adjustable draw-tube 15 upper and lower liftings can be made, thereby the operating fluid level in the raindrop water storage generator 2 can be regulated, and then the size of control raininess; Simultaneously, can also be by on described watering duct 6, laying the removable syringe needle 18 of different size, to satisfy the needs of raininess in the mensuration process.
For the ease of observing and regulate the water level in the raindrop water storage generator 2, the side near adjustable draw-tube 15 in the raindrop water storage generator 2 is provided with a gauge 19.
Before starting working, earlier adjustable lifting support 9 is connected, be adjusted to needed height, make raindrop water storage generator 2 maintenance levels; Be laid with the syringe needle 18 of different size on the duct 6 in watering, to reach needed raininess when measuring; Regulate the height of adjustable draw-tube 15, the scale of setting on its bottom and the gauge 19 is flushed; Close variable valve 14 on the adjustable draw-tube 15 and the variable valve 20 on the filling pipe 5, open the variable valve 12 on the filler 3, in water supply installation 1, after the fills with water, close variable valve 12, make the vacuum state that forms sealing in the water supply installation 1; When beginning to measure, open variable valve 14 and variable valve 20 earlier, when the water level in the raindrop water storage generator 2 reaches setting scale on the gauge 19, form the vacuum state of sealing in the water supply installation 1 once more, filling pipe 5 no longer supplies water; When water level was lower than setting height, air was entered by adjustable draw-tube 15, and under the effect of air pressure, water flows out in filling pipe 5 automatically, begins to add water, stops to supply water when arriving setting height once more; By such homeostasis process repeatedly, make the water level of regulating raindrop water storage generator 2 be on the setting height all the time.
The present invention has realized that all processes of rainfall intensity and rainfall amount controls automatically, be convenient to carry out the field test of different gradient, and simple in structure, highly sensitive, in light weight, volume is little, easy to install, be suitable for field measuring, have bigger application value.
