Collection device and density measurement system

Abstract

The invention provides a collection device and a density measurement system, and relates to the field of mechanical devices. The collection device comprises an L-shaped plate, a collection box body and a handle; the L-shaped plate is composed of a bottom plate and a first side plate; the collection box body comprises a cover plate, a second side plate and a third side plate; the second side plateand the third side plate are perpendicular to the cover plate; the collection box is fastened on the bottom plate; the cover plate is parallel to the bottom plate, and a collection space is formed; the height of the second side plate and the height of the third side plate are smaller than a preset threshold value; and the handle is fixedly connected with the first side plate. By using the collection device, a to-be-measured sample with the fixed volume can be obtained; and the height of the second side plate and the height of the third side plate are smaller than the preset threshold value, sothat the purpose of carrying out layered sampling on a relatively thin to-be-measured object can be achieved. The device is simple in structure, light and easy to use; the collected data of the to-be-measured sample is accurate; and the collection device is not influenced by environmental factors.

Description

technical field [0001] The invention relates to the field of mechanical devices, in particular to a collection device and a density measurement system. Background technique [0002] Snow is one of the important water resources on the earth's land surface, and the mass per unit volume of snow is called snow density. When observing snow in the field, it is often necessary to measure the snow density. Due to the different particle sizes of the snow, it is necessary to layer the snow and observe the density of each layer of snow. In the study of snow cover, the study of snow density is of great significance to the study of snow water distribution, building loads and avalanche omens. [0003] The main electronic equipment for detecting snow density in the prior art is SnowFork, and the physical equipment includes snow cylinder and snow shovel. SnowFork mainly calculates the density of snow by measuring the dielectric constant of snow; the snow tube is used for the average densi...

Problems solved by technology

However, snow cylinders and snow shovels cannot be used when the stratified snow layer thickness is small, so there is a lack of a snow density verification device for places where the stratified snow layer thickness is small
