Embodiment 1

[0019] Such as figure 1 As shown, the portable rainfall simulation device of the present invention includes a support frame 1, a rainfall simulation nozzle 2, and a simulated rainfall water supply device 3. The support frame 1 is composed of a leg 11 and a frame 12. Leg 11 is fixed to the ground. The height of the frame 12 on its supporting legs 11 is adjustable up and down. The supporting legs 11 are composed of a support plate 11a and a sleeve 11b. The sleeve 11b is fixed on the support plate 11a. Through the installation and fixing holes 11c, the support plate 11a is fixed on the ground through the anchor bolt fixing holes 11c. The sleeve 11b is provided with a plurality of positioning holes 11d at appropriate distances along its length direction, and a ferrule 12a matching the inner hole of the sleeve 11b is provided under the frame 12, and the ferrule 12a is provided with At least one locking hole 12b matches the positioning hole 11d on the sleeve 11b, and the frame fer...

Embodiment 2

[0021] Such as figure 2 As shown, compared with the technical solution of Embodiment 1, the fixing method of the nozzle 22 in the rainfall simulation nozzle 2 has been changed in this embodiment, and each nozzle 22 is directly fixed with the frame 12 and arranged in parallel with each other. within a plane.

[0022] Before the portable rainfall simulation device is actually used, it needs to be calibrated and tested with a standard rain gauge. If any simulated rainfall is found to be uneven during calibration and detection, it can be corrected by adjusting the direction and number of water nozzles; in addition, the instantaneous rainfall value obtained by the water flowmeter can also be corrected by using the standard rain gauge.

Abstract

A portable rain-falling simulator is composed of a supporting frame consisting of supporting legs and frame, a spraying pipe system consisting of water trunk and a group of spraying pipes with several sprayers for each, and water supply system consisting of water pump and water tank.

Description

technical field [0001] The invention relates to a rainfall simulation device, in particular to a portable rainfall simulation device for studying landslides. Background technique [0002] In the study of landslides and mass landslides caused by rainfall, if the research is carried out under natural rainfall conditions, the total rainfall and rainfall per unit time cannot be measured. Therefore, an accurate rainfall simulation device is the key to the study of landslides. One of the key equipment. At present, there is an indoor rainfall simulation device, which can perform artificial volumetric measurements on landslides in an artificially simulated mountain environment. There is a large difference from the actual data, and the measurement results cannot truly reflect the actual situation. Contents of the invention [0003] In order to overcome the defects existing in the existing artificial mountain measurement, the purpose of the present invention is to provide a portab...
