Abstract
The invention discloses a rocker arm upward spraying type rainfall simulator. The rocker arm upward spraying type rainfall simulator comprises a bracket, a main water supplying pipe and a motor, and is characterized in that a shaft hole is formed in the upper end of the bracket and a cross-shaped rocker arm is arranged; the rocker arm is a cross-shaped water through pipe; the upward direction of the cross-shaped water through pipe is connected with a plurality of adjustable spherical spraying nozzles; the rocker arm is provided with a shaft pipe; the shaft pipe movably penetrates in the shaft hole formed in the upper end of the bracket; a motor is in transmission connection with a crank connecting rod mechanism; and a connecting rod of the crank connecting rod mechanism is hinged with the bottom of one end of the rocker arm. The spraying nozzles upwards spray out water columns in a reciprocating motion process so that wild simulated rainfall is realized. The rainfall device has a simple structure and strong operability and is convenient to move; and compared with similar equipment, for the rocker arm upward spraying type rainfall simulator disclosed by the invention, the energy consumption is greatly reduced and the natural randomness of the rainfall can be represented better.
Description
Technical field
The present invention relates to a kind of analogue experiment installation, particularly a kind of can the rocking arm upper-spraying type rainfall simulator of simulated rain trails on the spot in the wild.
Background technology
For the rainfall simulation experiment of different object, researchers devise multiple different simulated rainfall equipment, and existing Field simulation rain controller generally comprises: what 1) high trestle was equipped with lateral spray type or following spray rainfall shower nozzle builds mode, and shower nozzle is fixed on rainfall support; 2) scan following spray, shower nozzle, by driven by motor, the path of specifying is moved.Existing rainfall simulator, shower nozzle is generally arranged on higher support, and Jet with downward flow direction realizes simulated rainfall.Support is being built and time and effort consuming in unloading process, and mobility is poor, directly affects test process.In addition, the effective rainfall region that existing rainfall simulator covers is less, and raindrop characteristic such as Raindrop diameter, rainfall kinetic energy etc. and natural rainfall also have certain difference.Therefore, study that a kind of structure is simple, close to actual rainfall raindrop characteristic, and the light rainfall simulator of movement is very necessary for soil erosion dynamic monitoring work.
Summary of the invention
The object of this invention is to provide a kind of rocking arm upper-spraying type artificial raining-simulated apparatus, structure be simple, Rainfall Characteristics extremely close to natural rainfall, and mobile light.
The present invention seeks to realize like this: comprise and arrange support, main-supply and motor, it is characterized in that: in the upper end of support, axis hole is set, be provided with cross rocking arm; rocking arm is cross water service pipe; at the multiple adjustable spherical shower nozzle of the upwardly-directed connection of cross water service pipe; rocking arm arranges central siphon, central siphon activity is threaded onto in the axis hole of pedestal upper end; Motor-driven jointed crank connecting rod mechanism, the rod hinge connection of toggle is bottom one end of rocking arm.
Good effect of the present invention is: this rain controller volume is little, lightweight, and structure is simple; Decrease installation and operation link, be convenient to grasp operative skill; Compared with same category of device, energy consumption significantly reduces.With existing rainfall simulator generally adopt the mode of lower spray or side spray realize rainfall unlike, this rain controller adopts upward spraying type spray head, by rack-mount pressurization shower nozzle, water column is sprayed in the air, water column rises to 20 more than m by air resistance and the formation raindrop that scatter, and the to-and-fro movement of shower nozzle determines the scope in rainfall region; Make Rainfall Characteristics extremely close to natural rainfall.

Fig. 3 is cross rocker structure schematic diagram.
Embodiment
See Fig. 1-3, structure of the present invention is as follows: arrange support 5 and main-supply 8, and stacking pressure table 7 on the main-supply 8 connecting water pump, arranges axis hole 10 in the upper end of support 5; Be provided with the rocking arm 3 of " cross "; rocking arm 3 is cross water service pipe; adopt existing product at upwardly-directed connection multiple adjustable spherical shower nozzle 2(of cross water service pipe), " cross " rocking arm 3 on central siphon 1 is set, central siphon 1 activity is threaded onto in the axis hole 10 of support 5 upper end; Assembling motor 11 on support 5, motor 11 is in transmission connection toggle 6, and the connecting rod 4 of toggle 6 is articulated with bottom one end of rocking arm 3; Main-supply 8 is by the articulation 12 of flexible pipe 9 connecting rocker arm 3.
When motor 11 rotates, by the transmission of toggle 6, rocking arm 3 to-and-fro movement in certain amplitude of oscillation of " cross ", water column is sprayed in to-and-fro movement upward by adjustable spherical shower nozzle 2, and water column aloft to scatter formation rainfall by air resistance.Rainfall intensity and region can be controlled by regulating the hunting frequency of hydraulic pressure, " cross " rocking arm, shower nozzle quantity and nozzle angle in rainfall.
