Description
Technical field
The present invention relates to one portable, be applicable to the experimental provision that field snow density is measured.
Background technology
The quality of unit volume of snow is called the density of snow, i.e. the ratio of the density of snow of certain mass and its volume.The density of snow is one of Main physical feature of snow.In the research process such as the soil moisture, air themperature and humidity, climatic environment variation, snow density is used as an important parameter; In addition many Practical Projects and agricultural working carry out with implementation process in, snow density is also a necessary parameter, as judge the degree of local road P Passable, determine the construction of road in winter, and the loading that increases because of snow of definite building roof, measure the water cut in snow, research accumulated snow impact on crops and the ecosystem etc.Therefore the experimental provision of measuring in the urgent need to a kind of field snow density is realized convenient, to measure fast and accurately snow density object.
Summary of the invention
In view of above-mentioned, object of the present invention aims to provide a kind of portable, is applicable to the determinator that field snow density is measured.
The object of the present invention is achieved like this:
A kind of field snow density is measured determinator, comprises counterweight, rule, portable rope, test specimen tube lanyard, test specimen tube upper cover, test specimen tube cylindrical shell, scale form, test specimen tube lower cover, horizontal device.On test specimen tube cylindrical shell, be rotary with test specimen tube upper cover and test specimen tube lower cover, cylindrical shell has scale form, its lower end is cutting ring shape, counterweight is equipped with in rule one end, the other end has portable rope, and the groove of end hangs with test specimen tube lanyard and is connected with the test specimen tube upper cover on test specimen tube cylindrical shell on rule with horizontal device.
The beneficial effect of advantage of the present invention and generation is:
1, simple in structure, detachable, the operation of the present invention easily row, accuracy rate is high and be easy to carry, and can be used to the snow density test of affected field;
2, test specimen tube lower end bead is cutting ring shape, and sampling is convenient, on test specimen tube, with scale form, can measure intuitively the volume of snow core;
3, on rule, there is horizontal device, make counterweight balance on test specimen tube cylindrical shell snow core and rule, record snow core quality more accurate.
Accompanying drawing explanation
Fig. 1 is invention schematic diagram.
Fig. 2 is Fig. 1 rule schematic diagram.
Fig. 3 is test specimen tube cylindrical shell sectional schematic diagram.
Wherein: 1-counterweight; 2-rule; The portable rope of 3-; 4-test specimen tube lanyard; 5-test specimen tube upper cover; 6-cutting ring test specimen tube cylindrical shell; 7-scale form; 8-test specimen tube lower cover; 9-knife plate; 10-horizontal device.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is further described again:
As shown in Figure 1-Figure 3, a kind of portable, detachable, be used in field snow density determinator containing weighing device part and stereometry part.The part of weighing comprises counterweight 1, rule 2, portable rope 3; Stereometry part is divided into test specimen tube lanyard 4, test specimen tube upper cover 5, test specimen tube cylindrical shell 6, test specimen tube lower cover 8.On test specimen tube cylindrical shell 6, be rotary with test specimen tube upper cover 5 and test specimen tube lower cover 8, test specimen tube upper cover 5 and test specimen tube lower cover 8 all adopt stainless steel to make, and all detachable.Test specimen tube cylindrical shell 6 adopts stainless steel material to make, and opens the scale form 7 of organic glass on cylindrical shell, and its edge, lower end polishing, for cutting ring shape, is got snow core to facilitate.Counterweight 1 is equipped with in rule 2 one end, and the other end has portable rope 3, and portable rope adopts tygon Di Nima rope, durable wear-resisting.The groove of end hangs with test specimen tube lanyard 4 and is connected with the test specimen tube upper cover 5 on test specimen tube cylindrical shell 6, and on rule 2, with horizontal device 10, every little lattice are 10g.The heavy 1000g of counterweight 1.After the test specimen tube cylindrical shell 6 that is rotary with test specimen tube upper cover 5 and test specimen tube lower cover 8 that does not pack snow core product into is assembled, carry portable rope 3, mobile counterweight 1 be adjusted to rule 2 in bubble while mediating, record does not pack snow core product into and is rotary with test specimen tube cylindrical shell 6 weight of test specimen tube upper cover 5 and test specimen tube lower cover 8.
Counterweight 1 is installed on rule 2, while measuring volume, test specimen tube cylindrical shell 6 utilizes the cutting ring of edge polishing to insert very easily in accumulated snow, makes people's knife plate 9 shovel fast the unnecessary accumulated snow in cylindrical shell bead bottom and hold up test specimen tube cylindrical shell 6 with smooth surface stainless steel.Read the bulking value of snow core from cylindrical shell high scale form 7.
Measure the test specimen tube cylindrical shell 6 of test specimen tube upper cover 5 and test specimen tube lower cover 8 being screwed on after volume, test specimen tube lanyard 4 is hung in the groove of back on rule 2, mention whole test specimen tube cylindrical shell 6 with portable rope 3, the mobile counterweight 1 being installed on rule 2, when the bubble in leveling device 10 on rule 2 mediates, to guarantee rule 2 levels, on rule 2 position of counterweight 1 institute target scale be test specimen tube cylindrical shell 6 and snow core quality and, remove the weight of test specimen tube cylindrical shell 6, test specimen tube upper cover 5 and test specimen tube lower cover 8, thereby can obtain the quality of snow core.
According to the volume of snow core and mass ratio, can calculate very easily the density of snow core.
