A precipitation measuring device for observation in frozen land

Abstract

The present invention belongs to the technical field of precipitation measuring and calculating equipment, in particular to a precipitation measuring and calculating device for permafrost region observation, comprising a base, an outer cylinder is arranged above the base, and support columns are fixed at the four corners of the bottom of the outer cylinder, The bottoms of the support columns are all fixedly connected to the top of the base, and the top of the base is symmetrically fixed with support plates. The present invention can disassemble and assemble the measuring cylinder more conveniently by setting the support plate, two-way screw rod, knob, vertical plate, cross bar, splint and non-slip rubber pad. After the rainwater is collected, the measuring cylinder can be taken out more conveniently, so It is convenient for people to observe the amount of precipitation. By setting support plates, inserting blocks, right-angled triangle blocks, fixed blocks, guide rods, slide plates, first springs, trapezoidal blocks, connecting rods, rings and pressure plates, the rain funnel can be more conveniently carried out. Disassembly and assembly, so that when it needs to be carried, the rain funnel can be disassembled from the outer cylinder, so that the height can be reduced, so that people can carry it conveniently.

Description

technical field [0001] The invention relates to the technical field of precipitation measurement and calculation equipment, in particular to a precipitation measurement and calculation device for observation of permafrost regions. Background technique [0002] In my country's permafrost areas, such as Harbin, Dalian and other areas, it often rains. When it rains, the precipitation is generally measured. The precipitation refers to the liquid or solid ( After melting) precipitation, the depth of the accumulated water layer without infiltration, evaporation, and loss is called the precipitation of the place in this period, and the unit is mm. In meteorology, the amount of precipitation in a certain period of time is usually used to divide the intensity of precipitation. Currently, rain gauges are usually used to measure precipitation. [0003] However, at present, the rain gauge funnel does not have the function of preventing foreign objects. In windy weather, when rain falls,...

Problems solved by technology

[0003] However, at present, the rain gauge funnel does not have the function of preventing foreign objects. In windy weather, when rain falls, debris such as leaves and paper scraps may block the rain funnel, thus preventing rainwater from passing through the rain funnel. fall into the measuring cylinder, so it will lead to large errors in the calculation results, and the current rain gauge is prone to dumping when the wind is strong, and the height of the current rain gauge is relatively high, which is troublesome to carry, so we proposed A precipitation measurement and calculation device for observation of permafrost areas to solve the above problems
