Description
Technical field
The utility model is related to a kind of portable, it is adaptable to field snow density analyzer.
Background technology
The quality of the unit volume of snow is referred to as the ratio between the density of snow, the i.e. density of snow of certain mass and its volume.The density of snow is one of main physical characteristics of snow.In the research process such as the soil moisture, air themperature and humidity, Climate and Environment Variation, snow density is used as an important parameter；In addition in the development and implementation process of many Practical Projects and agricultural working, snow density is also a necessary parameter, such as judge the degree of local road P Passable, determine the construction of winter road, and determine building roof increased loading because of snow, determine the water content in snow, influence of the research accumulated snow to crops and the ecosystem etc..Therefore purpose that is convenient, fast and accurately determining snow density is realized in the urgent need to a kind of experimental provision of field snow density measure.
The content of the invention
In view of above-mentioned, the purpose of this utility model aims to provide a kind of portable, it is adaptable to the measure device that field snow density is determined.
What the purpose of this utility model was realized in：
Lid, test specimen tube cylinder, scale form, test specimen tube lower cover, horizontal device on a kind of field snow density analyzer, including counterweight, graduated scale, portable rope, test specimen tube lanyard, test specimen tube.Lid and test specimen tube lower cover on test specimen tube are rotary with test specimen tube cylinder, cylinder is provided with scale form, and its lower end is cutting ring shape, and graduated scale one end is equipped with counterweight, the other end has portable rope, and the groove of end hangs with test specimen tube lanyard and is connected with lid on the test specimen tube on test specimen tube cylinder on graduated scale with horizontal device.
Advantage of the present utility model and the beneficial effect produced are：
1st, the utility model is simple in construction, detachable, operates easy, accuracy rate high and is easy to carry, and can be used to affected field snow density test；
2nd, test specimen tube lower end bead is cutting ring shape, and sampling is convenient, and scale form is carried on test specimen tube, the volume of snow core can be intuitively measured；
3rd, there is horizontal device on graduated scale so that test specimen tube cylinder snow core is balanced with counterweight on graduated scale, measures snow core quality more accurate.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Fig. 2 is Fig. 1 graduated scale schematic diagrames.
Fig. 3 is Fig. 1 test specimen tube cylinder sectional schematic diagrams.
Wherein：1- counterweights；2- graduated scales；The portable ropes of 3-；4- test specimen tube lanyards；Covered on 5- test specimen tubes；6- cutting ring test specimen tube cylinders；7- scale forms；8- test specimen tube lower covers；9- knife plates；10- horizontal devices.
Embodiment
Below in conjunction with the accompanying drawings, the technical solution of the utility model is further described again：
As shown in Figure 1-Figure 3, it is a kind of portable, detachably, it is used in field snow density analyzer, part containing weighing device and stereometry part.Weighing section includes counterweight 1, graduated scale 2, portable rope 3；Stereometry part is divided into test specimen tube lanyard 4, lid 5, test specimen tube cylinder 6, test specimen tube lower cover 8 on test specimen tube.Lid 5 and test specimen tube lower cover 8 on lid 5 and test specimen tube lower cover 8, test specimen tube is rotary with test specimen tube on test specimen tube cylinder 6 to be made of stainless steel, and it is detachable.Test specimen tube cylinder 6 is made of stainless steel material, and the scale form 7 of lucite is opened on cylinder, and the polishing of its lower end edge is cutting ring shape, and snow core is taken to facilitate.The one end of graduated scale 2 is equipped with counterweight 1, and the other end has portable rope 3, and portable rope is restricted using polyethylene Di Nima, durable wear-resistant.The groove of end hangs with test specimen tube lanyard 4 and is connected with lid 5 on the test specimen tube on test specimen tube cylinder 6, and horizontal device 10 is carried on graduated scale 2, is 10g per small lattice.The heavy 1000g of counterweight 1.Being rotary with after the test specimen tube cylinder 6 of lid 5 and test specimen tube lower cover 8 on test specimen tube assembles of snow core product will be not loaded into, portable rope 3 is carried, when the bubble that mobile counterweight 1 is adjusted in graduated scale 2 is in an intermediate position, record is not loaded into the weight of test specimen tube cylinder 6 that snow core product are rotary with lid 5 and test specimen tube lower cover 8 on test specimen tube.
Counterweight 1 is installed on graduated scale 2, when determining volume, the cutting ring that test specimen tube cylinder 6 is polished using edge can be inserted very easily in accumulated snow, and people's knife plate 9 is made of the smooth stainless steel in surface, and quickly shovel falls the unnecessary accumulated snow in cylinder bead bottom and holds up test specimen tube cylinder 6.The bulking value of snow core is read from cylinder high scale form 7.
Determine and lid on test specimen tube 5 and test specimen tube lower cover 8 are screwed on into test specimen tube cylinder 6 after volume, test specimen tube lanyard 4 is hung on graduated scale 2 in the groove of back, lift whole test specimen tube cylinder 6 with portable rope 3, the mobile counterweight 1 being installed on graduated scale 2, when the bubble in leveling device 10 on graduated scale 2 is in an intermediate position, to ensure the level of graduated scale 2, on graduated scale 2 the position institute target scale of counterweight 1 quality then for test specimen tube cylinder 6 and snow core and, the weight of lid 5 and test specimen tube lower cover 8 on removing test specimen tube cylinder 6, test specimen tube, so as to obtain the quality of snow core.
According to the volume and mass ratio of snow core, the density of snow core can be very easily calculated.
