A liftable and portable simulated rainfall device suitable for highly heterogeneous karst slopes

Abstract

The present invention discloses a lifting portable simulation rainwater suitable for high heterogeneous Karst Places.It includes a four -nozzle combined rainfall generator, water supply system and lifting simulation rainwater bracket.The four -nozzle combined rainfall generator and the water supply system are twisted with the second right corner elbow; inserted the DN25 water pipe into the DN32 tube, and then screwed into the bolt into the third -level fixed nut to bring the water supply systemConnect with the lifting of the lifting rainfinder bracket; both ends of the three -level three -tech supervisor are connected to the second -level tri -link support through the two -level tri -link.Cailing connection.The present invention uses a combined nozzle, highly adjustable, easy to carry, and simple production, which solves the bottleneck of launching and erosion research in areas such as Karst -like are strongly heterogeneous.

Description

technical field [0001] The invention belongs to the technical field of artificial rainfall simulation, and more specifically relates to a liftable portable simulated rainfall device suitable for highly heterogeneous karst slopes, which is suitable for teaching, scientific research and environmental protection departments to carry out erosion and hydrological monitoring under various vegetation and land use types. and nutrient transfer studies. Background technique [0002] The water storage capacity of the shallow soil layer in the karst area of ​​Southwest China is weak, coupled with the abundant karst pores and fissures, the surface water leaks a lot, the groundwater pollution is becoming more and more serious, and the drought and flood disasters are frequent. Water is the key to solve the ecological problems in the karst area and achieve sustainable social and economic development. key. Therefore, in order to deepen the understanding of the hydrological cycle in karst ar...

Problems solved by technology

However, the structure and performance of the existing simulated rainfall devices are not yet suitable for the study of karst slope hydrology

First of all, the existing simulated rainfall devices cannot flexibly adjust the sprinkling height according to the height of the ground cover, and cannot adapt to the diverse vegetation and land use types in karst areas; secondly, most of the existing simulated rainfall devices have complex structures, time-consuming disassembly and assembly, and require a wide erection site, which is not easy It is transported and operated on complex hillsides similar to karst areas; thirdly, most of the existing simulated rainfall devices are expensive to manufacture, and it is basically impossible to manufacture them in large quantities. The invention is simple to manufacture and can be quickly realized by simple processing of commonly used pipes. low cost
