Problems solved by technology

The current general-purpose samplers (such as snow scales) measure snow density higher than the actual value by 0.3-10.3%, because the cylindrical sampler squeezes the surrounding snow into it, due to uneven force (the same different times or different people) resulting in large differences in the volume of snow samples collected multiple times

Embodiment Construction

[0029] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings. Several embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

[0030] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. As used herein, the terms "vertical," "horizontal," "left," "right," "u...

Abstract

The invention discloses a glacier shallow hard snow ice density measuring device and a glacier shallow hard snow ice density measuring method. The device comprises a hard snow ice collecting assemblyand a weighing assembly. The hard snow ice collecting assembly comprises a drill body and a drill tool. The drilling tool is of a barrel-shaped structure. An opening of the drilling tool faces outwards, the drilling tool is installed on the drilling body, the edge of the drilling tool is provided with tool teeth used for cutting snow ice, the drilling body is used for controlling the drilling toolto rotate in the axial direction, the weighing assembly is provided with a hook used for hooking the hard snow ice collecting assembly, the drilling body comprises a shell and a power machine body arranged in the shell, and the power machine body is provided with a mandrel connected with the drilling tool. According to the invention, deformation or damage to the internal structure caused by uneven stress in the snow ice extraction process is effectively avoided, and the measurement precision is improved. The drilling tool is utilized, so that single-point data can be measured for multiple times, unstable and abnormal values of manual single-time measurement are effectively reduced, and the measurement precision is further improved. The invention further discloses a snow ice density measuring method adopting the device.

Description

technical field [0001] The invention relates to the technical field of snow and ice density measurement, in particular to a device for measuring the density of hard snow and ice in shallow glacier layers and a method for measuring the density of snow and ice. Background technique [0002] Snow and ice density is the weight per unit volume of snow and ice, which is related to snow age, snow depth and climatic conditions. It is the most basic and easily measurable physical property of snow and ice research. The basic physical parameter of snow and ice density is not only an important parameter for the evolution of snow and ice, ice formation, reconstruction of ice core net accumulation and calculation of glacier mass balance, but also for the study of water balance in snow-covered areas, simulation of snowmelt runoff, avalanche forecasting and construction. The calculation of material snow and load is also of great significance. [0003] At present, the acquisition of snow an...
