Precipitation measurement and calculation device for frozen soil region observation

Abstract

The invention belongs to the technical field of precipitation measurement and calculation equipment, and particularly relates to a precipitation measurement and calculation device for frozen soil region observation. The device comprises a base, an outer cylinder is arranged on the base, support columns are fixed at four corners of the bottom of the outer cylinder, the bottoms of the support columns are fixedly connected with the top of the base, and support plates are symmetrically fixed to the top of the base. By arranging the support plates, the two-way lead screw, the rotary knob, the vertical plate, the transverse rod, the clamping plate and the anti-skid rubber pad, the measuring cylinder can be disassembled and assembled more conveniently, and after rainwater is collected, the measuring cylinder can be taken out more conveniently, so that people can observe the precipitation amount conveniently; and by arranging the supporting plate, the inserting block, the triangular block, thefixing block, the guide rod, the sliding plate, a first spring, a trapezoidal block, a connecting rod, a circular ring and a pressing plate, a rain containing funnel can be conveniently disassembledand assembled, so that when needing to be carried, the rain containing funnel can be disassembled from the outer barrel, the height can be reduced, and people can conveniently carry the rain containing funnel.

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
