Abstract
The invention discloses a rain simulating device for lab, which includes bracket, water pump, water converter, and water transmission channel, and valve, sprayer and control device. One inlet and several outlets are arranged on the water converter, the pump is connected with the inlet of the water converter, each inlet of the water converter is connected to the sprayer through valve, transmitting channel. The sprayer is arranged on the bracket through transmitting channel. The device controls the valve to act. The invention uses pump to press, and transmits them to each sprayer through water converter, controls the open quantity, size and spraying time of sprayers through the control device, it can realize real simulation to the natural rain, it has characters of small error, automatic control, wireless remote control.
Description
Technical field
The present invention relates to a kind of rainfall simulator that in the laboratory, uses.
Background technology
People are when studying the geology soil layer, when especially coming down test, need select satisfactory place to carry out hands-on demonstration out of doors according to research object, before this geology soil layer was explored, confirm that its geologic structure and the soil body constitute, select the suitable gradient to set up the large-scale spray equipment of simulating nature rainfall again, though such modeling effort can reflect the influence of rainfall to soil layer strictly according to the facts, obtain real data, but its research process is too tediously long, workload is big, need to drop into great amount of manpower, material resources, and revision test can not be carried out in same place, therefore people wish can be by carrying out simulation test at the indoor various soil layer models of setting up the simulating nature structure, to overcome the defective of outdoor hands-on demonstration, but this just has higher requirement to rainfall simulation system, and the injection flow rate of the device of generally drenching with rain, the water spray position, the not easy to operate and regulation and control of analog parameter that fogging degree etc. are crucial, can not realize the even branch of randomness of rainfall area, there is very big difference with actual rainfall situation, can not satisfies the test needs.
Summary of the invention
At the deficiencies in the prior art, the object of the present invention is to provide that a kind of rainfall simulation error is little, rainfall area can be at random evenly branch and can control automatically, the rainfall simulator of wireless remote control.
For achieving the above object, rainfall simulator of the present invention comprises support, water pump, flow converter, aqueduct, valve, shower nozzle and control device, flow converter is provided with water inlet and some water delivering orifices, water pump is connected with the flow converter water inlet, each water delivering orifice of flow converter is through valve, aqueduct, be connected with shower nozzle, shower nozzle is rack-mount by aqueduct, the work of control device by-pass valve control.
Further, described valve is a solenoid valve.
Further, described shower nozzle is senior atomizer.
Further, the soft pipeline of described water-supply-pipe for adopting flexible material to make.
Further, described control device also comprises the telepilot adaptive with it.
Further, described support is provided with mounting hole and the clamp device that matches with aqueduct, and aqueduct can freely stretch in mounting hole and fix.
Rainfall simulator of the present invention pressurizes water with water pump, flows to each shower nozzle by flow converter again, and size and water spraying time by control device control shower nozzle is opened quantity, each shower nozzle injection flow rate can realize the real simulation to natural precipitation.

Embodiment
As shown in Figure 1, rainfall simulator of the present invention pressurizes water with water pump, flow to each shower nozzle by flow converter again, by the unlatching quantity of control device control shower nozzle, the size and the water spraying time of each shower nozzle injection flow rate, thereby realization is to the real simulation of natural precipitation.
As shown in Figure 2, flow converter 1 is a rectangular parallelepiped water tank, the water delivering orifice 2 that a water inlet 3 is arranged on it and be provided with by suitable pitch arrays, water delivering orifice quantity is decided according to the rain area of required simulation, water inlet 3 is connected with water pump by pipeline, each water delivering orifice 2 place is equipped with solenoid valve, the control knob of solenoid valve is concentrated by connection line and is arranged on the wiring board, also be provided with the infrared remote control receiver of making according to prior art on the wiring board simultaneously, can realize control by Infrared remote controller to solenoid valve, made things convenient for use, water delivering orifice 2 is communicated with (part only is shown among the figure) by aqueduct 4 with shower nozzle 5, support 7 is provided with the mounting hole 6 that is complementary with aqueduct 4, as shown in Figure 3, mounting hole 6 is by suitable pitch arrays setting, and water-supply-pipe 4 passes mounting hole 6 and is erected on the support 7, all is provided with the clamp device that water-supply-pipe 4 is fixed on each mounting hole.
As shown in Figure 4, in indoor when experiment of coming down, intend the soil layer model 9 of natural structure earlier at simulation box 8 built-in formwork erections, support 7 is installed in simulation box 8 tops, make shower nozzle down, aim at soil layer model 9, by the gradient of soil layer model 9 operation clamp device shower nozzle is adjusted to suitable height again, next just can regulate rainwater flow and rainfall intensity, simulate various rainfall situations by the size that telepilot is controlled shower nozzle unlatching quantity and each shower nozzle injection flow rate.
In addition, the utility model also can be united use with other instruments, and corrosion-resistant, the anti-performance such as wash away of material is tested and studied.
