AI Technical Summary

Problems solved by technology

[0006] (1) The range of rain intensity is small, and the same set of devices usually cannot simulate light rain, moderate rain, heavy rain, and heavy rainfall
[0007] (2) The controllability is poor. Generally, the test device can only simulate a certain intensity of rainfall, but cannot simulate rainfall of different rainfall intensities in different regions.
[0008] (3) Existing test devices can usually set a certain rainfall intensity to simulate rainfall, but cannot automatically and accurately simulate actual rainfall according to a certain rainfall duration
[0009] (4) Existing experimental devices usually cannot predict the rainfall in the next time period based on a certain rainfall duration data
[0010] (5) Most of the existing test devices are fixed test racks, which cannot be moved at will according to the test needs

Embodiment 1

[0023] Embodiment 1: structure and use of test device

[0024] Such as figure 1 As shown, the present invention includes: a circulating water supply system 1, an intelligent controller 2, a computer and software system 3, a distributed sprinkler 4, a mobile retractable test frame 5 and a windproof structure 6. The circulating water supply system 1 is composed of a water supply tank 101 , a water pump 102 , a water pressure regulator 103 , an upper water pipe 104 , a water collection tank 107 , a connecting pipe 105 and a filter 106 . The water collecting tank 107 is connected with the filter 106 through the connecting pipe 105, and then connected with the water supply tank 101 through the connecting pipe 105 to form a water circulation channel. Wherein, the water collection tank 107 mainly collects the simulated rainfall, and the filter 106 is used to purify the collected simulated rainfall, and transport it to the water supply tank 101 through the connecting pipe 105 for reu...

Embodiment 2

[0035] Embodiment 2: the preparation of formula I polymer

[0036]Step 1: Using trimethylsilylacetylene as a raw material, under the condition of nitrogen protection at -78°C, react with butyllithium and 4,4'-dibromobenzophenone in equal amounts to form a hydroxyl-containing terminal alkyne bond Compound; the specific operation is: add 17mmol TMSA to a 250ml three-necked flask, add 30ml anhydrous tetrahydrofuran, cool to -78°C, slowly add 15.6mmol of 2.4M butyllithium solution dropwise, and keep warm for 30min. 14.2 mmol of 4,4'-dibromobenzophenone was added. After 12 hours, deionized water and 14.2 mmol of tetrabutylammonium fluoride were added. The organic layer was extracted with dichloromethane, spin-dried and passed through the column with dichloromethane:petroleum ether=3:1 to obtain a light yellow solid compound.

[0037] Step 2: The product obtained in step 1 is catalyzed by pyridine p-toluenesulfonate with a mole fraction ratio of 5%, and undergoes a dehydration rin...

Abstract

The invention discloses an intelligent artificial rainfall simulator which comprises a circulating water supply system, an intelligent controller, a computer and software system, a distributed spraying rainfall device, a movable telescopic test frame and a wind-proof structure. An upper spray pipe, a lower spray pipe and sprayers are combined to form the distributed spraying rainfall device, the diameter of the upper spray pipe is different from that of the lower spray pipe, the diameters of the sprayers correspond to those of spray nozzles, the wind-proof structure is arranged below the rainfall device, can be fixed on the inner side of the test frame and prepared from polymer in a formula I, Mw of the high-molecular polymer is 5.115*104, and a molecular weight distribution index is 1.761.

Description

technical field [0001] The invention relates to an intelligent artificial rainfall simulation device, in particular to a portable rainfall simulation device for studying geological disasters such as landslides and debris flows. This patent was funded by the National 973 Project "Full Life Cycle Performance Evolution and Safety Control of High and Steep Slopes of Large Water Conservancy and Hydropower Projects". Background technique [0002] Rainfall, as an important factor inducing slope disasters, has always been concerned by scholars at home and abroad. Geological disasters such as landslides and mud-rock flows caused by rainfall have seriously harmed many regions and cities, causing a large number of casualties and property losses, and have greatly affected economic construction and social stability. For example, on August 7, 2010, Zhouqu County, Gansu Province, due to heavy rainfall, caused a severe mountain torrent geological disaster, and the area where the debris flo...
