Abstract
The utility model provides a snow cover bearing strength measurer. The snow cover bearing strength measurer comprises a pyramid-type cylinder-shaped shell body, a top cover and a handle, wherein the top cover is arranged on the pyramid-type cylinder-shaped shell body, a top cover button knob is arranged on the top cover, the handle is arranged on the top cover button knob, and the scales which are used for indicating bearing strength measuring results are arranged on the pyramid-type cylinder-shaped shell body. When the snow cover bearing strength measurer is used for measuring, a pyramid tip end is put on the snow surface, the snow cover bearing strength measurer is let go and capable of freely falling into snow cover, and a snow cover bearing strength value corresponding to a ring line where the snow surface reaches is recorded, if balance weight is used, the recorded value is then multiplied with a balance weight coefficient, and then the snow cover layer load bearing strength can be obtained. The snow cover layer bearing strength measurer is capable of measuring the snow cover bearing strength conveniently, speedily and accurately, simple in structure, small in size, convenient to carry and low in cost.
Description
(1) technical field
The utility model relates to the device that a kind of outdoor habitats were factor is measured, and relates in particular to a kind of measuring appliance that can quick and precisely measure the snow cover loading strength.
(2) background technology
At present, in domestic zooecology research, the character measurement of snow cover is mainly snow cover thickness.And also there is significant impact in the loading strength of snow cover to the activities such as motion of animal.For the flat board that is placed on the snow face is exerted pressure, the maximum, force when recording the snow face and being depressed adds the gravity of upper flat plate, divided by the area of flat board, obtains the snow cover loading strength to the general measuring method of snow cover loading strength.The method is used comparatively trouble, operator's operant level and measuring technique are had relatively high expectations, under the environment of cold operation more difficult, and measure consuming time longlyer at every turn, be difficult to satisfy the requirement of Quick Measurement.Although the loading strength of snow cover is one of can not uncared-for factor of the habitat, because it is difficult to measure, have to yield in most of practical study work.
(3) summary of the invention
The purpose of this utility model is to provide a kind of deficiency that can make up existing snow cover loading strength measuring method, can not only measure the snow cover loading strength, and measuring method is simple, and process is succinct, the snow cover loading strength measuring appliance that accuracy is higher.
The purpose of this utility model is achieved in that it comprises pyramid type tubular shell 1, top cover 2 and handle 4, top cover 2 is arranged on pyramid type tubular shell 1, be provided with top cover knob 3 on top cover 2, handle 4 is arranged on top cover knob 3, and the indication measurement scale 5 of loading strength as a result is arranged on pyramid type tubular shell 1.
The utility model also has some technical characterictics like this:
1, described scale 5 indicates for being arranged on the circular cone side loop wire that is parallel to the circular cone bottom surface;
2, described scale 5 values comprise 4 row loop wires with 90 ° of intervals;
3, be provided with balancing weight 6 in described pyramid type tubular shell 1;
4, described top cover is demountable structure, is threaded with pyramid type tubular shell 1;
5, described taper shaped cylindrical housing 1 and top cover 2 are structure as a whole.
The technical scheme that its technical matters that solves the utility model adopts is: take the pyramid type tubular shell as the basis, top cover be demountable structure or and taper shaped cylindrical housing be structure as a whole, and have handle, be used for lifting and loading different counterweights.Pyramid type tubular shell side indicates the loop wire that is parallel to the circular cone bottom surface, and marks snow cover loading strength value corresponding to this loop wire (pressure, unit is Pascal).The handle of the portable circular cone top cover of gauger during measurement, shaped cylindrical housing epiconus is put on the snow face, decontrol handle and compress into snow cover by the measuring appliance free-falling, measuring device to be measured stops snow cover loading strength value corresponding to rear record snow loop wire that face reaches, and can obtain the snow cover loading strength.
The beneficial effects of the utility model are, can measure convenient, fast, exactly the snow cover loading strength, and simple in structure, and volume is little, is easy to carry, and cost is low.
(4) description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is basis schematic diagram of the present utility model.
Fig. 3 is the structural representation of the utility model balancing weight.
(5) embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
In conjunction with Fig. 1, snow cover loading strength measuring appliance pyramid type tubular shell 1, top cover 2 and handle 4 form.The scale 5 of the loading strength of indication measurement result is engraved on pyramid type tubular shell 1, this scale value calculates according to measuring appliance deadweight (M), measuring appliance centrum side long (L) and cone end radius (R), in conjunction with Fig. 2, as longly in the centrum side that the snow face did not have when measuring be l, centrum bilge redius r=lR/L of not having of snow face; The centrum area S=π r l that this moment, the snow face did not have=π l
2R/L.Represent snow cover pressure with P, by pressure formula P=F/S, make a concerted effort to calculate formula F=GL/R, and gravity G=Mg can calculate, P=MgL
2/ π R
2l
2, wherein, g is acceleration of gravity.
Taper shaped cylindrical housing 1 is made by metal material, if with proportion lighter aluminium alloy or plastics, need filling part lead so that certain deadweight to be provided in its vertex of a cone, when centrum shape and center of gravity can guarantee to measure on the lower side, measuring appliance can rely on the stable snow of compressing into of gravity.Top cover 2 is combined with centrum by screw thread, by top cover knob 3 conveniently assemble and disassemble balancing weights 6.Scale 5 values of the loading strength of indication measurement result are with 90 ° of interval mark 4 row, to facilitate reading result.In conjunction with Fig. 3, balancing weight 6 is plumbous derby processed, and shape and measuring appliance inner space adapt, and the quality of each balancing weight is 50% of measuring appliance sole mass, so that result of calculation after the use counterweight.Use counterweight can expand the range ability of measuring appliance.This embodiment makes the gauger that measuring appliance is placed on the snow face can directly read the snow cover loading strength, simple and quick.
In simplified embodiment, taper shaped cylindrical housing 1 and top cover 2 are structure as a whole, and do not possess the function of using balancing weight 6, only can measure the snow cover loading strength in the range ability of measuring appliance own.
