Abstract
The utility model discloses a small -size artifical rainfall simulation device, including long and a wide panel that is 0.35m, arrange the motor on the panel, the power cord is laid to controller and water pressure gauge, controller and motor, the electric machine control rainfall horizontal hunting of meeting and discussing, arrange a rainfall shower nozzle under the panel, the rainfall shower nozzle has the PVC union coupling with the water pressure gauge. Install with the water tank panel below one side, has the inlet tube with on the water tank, and the immersible pump is laid by the incasement portion of adding water, and dive pumps water and passes through PVC union coupling water pressure gauge. Return water tank is installed with adding the relative opposite side of water tank in the panel below, collects unnecessary precipitation, and return water tank gets back to water with the water tank through the PVC pipe, carries out reuse. The utility model discloses, can effectively simulate various rainfall incidents to can carry out the combination and the split of multiple devices, realize that needs are simulated in the rainfall of different scopes.
Description
Technical field
The utility model relates to the experimental installation of simulated rainfall in a kind of soil conservation, is specifically related to a kind of rainfall generating unit for miniaturization.
Background technology
Artificially-simulated rainfall technology is the domatic hydrology process of research, plants physical growth, soil erosion mechanism, and the important technical of the mechanism of landslide debris stream disaster. The multiple rainfall simulation technology such as before 60 years 20th century, the U.S. just starts to study artificially-simulated rainfall technology, develops following spray, surveys spray formula, rotary, rainfall area is from 0.5m2To 50m2. Subsequently by the continuous research to natural rainfall, progressively achieve again different rainfall raindrop size, the control that rainfall intensity and rainfall last so that artificially-simulated rainfall technology is progressively ripe, and is widely used in the world. China, since the eighties in last century, has progressively started using artificial simulated rainfall technology, is the direct introduction to American technology and improvement on the one hand, is that the actual needs according to China develops characteristic rainfall technology on the one hand.
But all there are some shortcomings in simulated rainfall technology domestic and international at present, external technology relative maturity, but rainfall device volume is big, and comparatively heavy, fixing rainfall scope can only be simulated. And the rainfall simulation technology of domestic development is mainly not accurate enough to the control of characteristics of rainfall, the energy showing as raindrop is inadequate, and rainfall process and natural rainfall exist larger difference, and the spatial uniformity of rainfall is lower.
Practical novel content
The technical problems to be solved in the utility model is to provide the small test device of the different rainfall process of a kind of accurate simulation.
The utility model is achieved in that
A kind of Minitype manual simulated rainfall device, comprises a long and wide panel being 0.35m, arranges motor, controller and water pressure gauge, lay supply lead between controller and motor on panel, and electric machine control rainfall swings about meeting and discussing; Panel arranged just beneath rainfall shower nozzle, rainfall shower nozzle has pvc pipe to be connected with water pressure gauge.Described lower panels side is provided with and adds water tank, adds and has water inlet pipe on water tank, adds water tank placed inside submersible pump, and submersible pump water outlet connects water pressure gauge by pvc pipe. Another side that lower panels is relative with adding water tank is provided with recovery tank, collects unnecessary precipitation, and recovery tank is returned to water by pvc pipe and adds water tank, reuses.
Wherein add water tank, the top of recovery tank have opening, for collect rainfall meet and discuss be positioned at the left and right sides time ejection water.
Rainfall device of the present utility model is integrated with the various parts that simulated rainfall needs, it is achieved that miniaturization.
When specifically using, simulated rainfall device is placed on the high support of 2.7m, ensures rainfall device level, by plant-grid connection controller, water source is accessed water inlet pipe, rainfall device can be started and carry out simulated experiment.
When simulating actual precipitation event, the intensity of precipitation is controlled by adjusting the pressure size of water pressure gauge, by electric machine control rainfall nozzle right swing, the frequency of swing can be arranged, thus make to be positioned at the precipitation intensity of the trial plot immediately below rainfall shower nozzle, frequency is adjustable. And rainfall shower nozzle is not when having left and right to swing, be point to be positioned at both sides add above water tank and recovery tank, now add water tank and recovery tank just all serves the effect collecting unnecessary precipitation, avoid the waste of water. Because in the rainfall event of reality, through research, in fact precipitation is not isodensity, evenly landing, and centre has certain degree of closing and intermittent, passes through the utility model, can effectively simulate various rainfall event, and combination and the fractionation of multiple devices can be carried out, it is achieved the rainfall simulation of different range needs, it is possible to move easily, can use at indoor and outdoors, for carrying out the technique means of soil conservation, the ecological hydrology, geologic hazard research offer science.
Accompanying drawing explanation
Fig. 1 is simulated rainfall apparatus structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of Minitype manual simulated rainfall device, comprises a long and wide panel 4 being 0.35m, arranges motor 1 on panel 4, and controller 2 and water pressure gauge 3, lay supply lead between controller 2 and motor 1; Panel 4 arranged just beneath rainfall shower nozzle 8, rainfall shower nozzle 8 has pvc pipe to be connected with water pressure gauge 3. Panel lower left is installed and is added water tank 6, adds and has water inlet pipe 5 on the left of water tank 6, adds water tank 6 placed inside submersible pump 7, and submersible pump 7 water outlet connects water pressure gauge 3 by pvc pipe. Panel lower right installs back water tank 9, collects unnecessary precipitation, and recovery tank 9 is returned to water by pvc pipe 10 and adds water tank 6, reuses. Add water tank 6 and recovery tank 9 is inclined upwardly at a certain angle, it is connected with panel 4.
