Abstract
The utility model aims to solve the problem of measuring the density of the snow layer simply and conveniently and with high precision. The portable snow layer density measuring device comprises a cylinder, a snow shovel, a pushing end and a weighing instrument, wherein when the snow shovel is used, the snow shovel is horizontally inserted into the bottom of the cylinder to divide accumulated snow and the ground in the cylinder; when the pushing end is used, the pushing end is pushed into the bottom of the cylinder to push the accumulated snow in the cylinder upwards; the weighing instrument is used for weighing the weight of the accumulated snow inside; the cylinder is made of transparent material, and scales are arranged on the outer surface or/and the inner surface of the cylinder and used for measuring the snow depth and the position of the flat end in the cylinder. The device directly measures the accumulated snow with different depths at one time to measure the density of the snow layer, does not need to dig a pit, and is simple and convenient to operate; because the snow accumulated in the cylinder is pressed less, the volume and the density of the cylinder are basically kept unchanged, and the measurement precision of the density of the snow layer is higher.
Description
Technical field
The utility model relates to the different depth snow deposits in accumulated snow field of scientific study, especially accumulated snow scientific data acquisition
Density measure.
Background technique
Snow deposit density is accumulated snow hydrological model, the important parameter in accumulated snow quantitative remote sensing, and therefore, snow deposit density measure is in product
It avenges extremely important in scientific research.Currently, being Snow Fork snow characteristic point respectively there are mainly two types of snow deposit density measuring equipments
Analyzer and wedge-shaped snow gauge.
Snow Fork can measure the electrical parameters such as resonant frequency, the dough softening and 3 dB bandwidths, and utilize these measured values
It is precisely calculated dielectric constant, snow deposit density is then calculated by semiempirical equation.There are at least two: 1. snow deposits
Density is transformed by a variety of electrical parameters, and measurement result transmission error is big；2. when accumulated snow humidity is larger, temperature is lower,
The electrical parameter error measured is larger, leads to the snow deposit density inaccuracy being calculated；3. instrument cost is high, and is not easy to high and cold
Mountain area field carries.
Wedge-shaped snow gauge takes wedge-shaped snow gauge volume every certain snow depth when use on accumulated snow sectional elevation
Then the accumulated snow of size weighs and calculates snow deposit density.There are problems that not necessarily being close to wedge shape when at least two: 1. accumulated snow take
Snow gauge has gap between the two, and the accumulated snow volume taken and wedge-shaped snow gauge volume is caused to have certain error；2. accumulated snow is dug
It is pressurized when taking, density of snow changes, and leads to the snow deposit density inaccuracy being calculated.
In addition, above two snow deposit density measuring equipment, when use, is required to dig pit and sectional elevation, measurement process are time-consuming
Effort error is big, is badly in need of easy, high-precision snow deposit density measuring equipment.
Summary of the invention
Problem to be solved in the utility model is easy, accurately measure snow deposit density.
Portable snow deposit density measuring equipment, including cylinder, snow cave shovel are bulldozed end, and weighing instrument, snow cave shovel is in use, horizontal insert
Enter bottom of cylinder, divides cylinder interior accumulated snow and ground；End is bulldozed in use, push-in bottom of cylinder, internal accumulated snow is up pushed away；
Weighing instrument is used to weigh the weight of internal accumulated snow；The material of cylinder be it is transparent, cylinder outer surface or/and inner surface are provided with quarter
Degree, for the position in cylinder where measuring snow depth and being bulldozed end.
Preferably, cylinder cross-sectional area 20-100 square centimeters, 10-150 centimetres of cylinder heights.
Preferably, cylinder upper end outer is to thicken, and hand contacts the position when use.
Preferably, being bulldozed end upper end is cylindrical body, and diameter is equal to barrel bore, and being bulldozed end lower end is handle.
Preferably, the ontology of snow cave shovel is planar shaped, and area is greater than cylinder cross-sectional area.
The accumulated snow that the device disposably directly measures different depth carries out the measurement of snow deposit density, it is not necessary to it digs pit, operation letter
Just；Since accumulated snow compression is smaller in cylinder, volume and density are held essentially constant, and snow deposit density measurement accuracy is higher；It is bulldozed
Holding upper end is that diameter is equal to or slightly less than barrel bore, can guarantee that being bulldozed end and cylinder inner wall is in close contact, will be complete in cylinder
Portion's accumulated snow up pushes away, and reduces measurement error；The ontology of snow cave shovel is planar shaped, and centre guarantees snow cave shovel and cylinder without carinate protrusion
Bottom end fits closely, and reduces accumulated snow volume inaccuracy bring error.
Detailed description of the invention
Fig. 1 is portable snow deposit density measuring equipment overall structure diagram；
Fig. 2 is the device usage schematic diagram；
Fig. 3 is that the device is bulldozed end structure schematic diagram.
In figure: 1. cylinders, 2. snow cave shovels, 3. are bulldozed end, 4. accumulated snow, 5. scales.
Specific embodiment
Embodiment 1
As shown in Figure 1-3, portable snow deposit density measuring equipment, including cylinder, snow cave shovel, it is bulldozed end, weighing instrument, snow cave shovel makes
Used time is horizontally inserted into bottom of cylinder, divides cylinder interior accumulated snow and ground；Be bulldozed end in use, push-in bottom of cylinder, will be internal
Accumulated snow up pushes away；Weighing instrument is used to weigh the weight of internal accumulated snow；The material of cylinder is transparent, cylinder outer surface or/and interior
Surface is provided with scale, for the position in cylinder where measuring snow depth and being bulldozed end.
20-100 square centimeters of cylinder cross-sectional area, 10-150 centimetres of cylinder heights.
Cylinder upper end outer is to thicken, and hand contacts the position when use.
Being bulldozed end upper end is cylindrical body, and diameter is equal to barrel bore, and being bulldozed end lower end is handle.
The ontology of snow cave shovel is planar shaped, and area is greater than cylinder cross-sectional area.
As shown in Figs. 1-2, the device application method is as follows:
When cylinder being a. inserted vertically into accumulated snow bottom, cylinder side accumulated snow is opened with snow cave shovel shovel, and snow cave shovel is horizontally inserted into circle
Cylinder and internal accumulated snow are taken out together, then remove the accumulated snow of cylindrical outer adhesion by cylinder bottom；B. be bulldozed end from the bottom up
Accumulated snow is pushed away, is overlapped accumulated snow upper end with cylinder upper end, and keeps the position for being bulldozed end constant, reads snow depth；
C. accumulated snow equally is pushed away for 2-5 centimetres from the bottom up with being bulldozed end every time, so that accumulated snow is emerged cylinder, strike off on cylinder
End, collects the accumulated snow emerged and weighs its weight on weighing instrument；D. the cylinder volume of the accumulated snow weight and release that weigh every time
Ratio, the snow deposit density of depth as where the accumulated snow.
