Abstract
The utility model discloses a portable tool for measuring breast-height diameter and ground diameter of mangrove plant, which comprises the following components: a vertically arranged supporting rod, an upper vernier caliper and a lower vernier caliper which are arranged above and below the supporting rod and are parallel with each other. The top end of the supporting rod is provided with a handle. The bottom of the supporting rod is provided with a fixing rod which is coaxially arranged with the supporting rod. The portable tool for measuring the breast-height diameter and the ground diameter of the mangrove plant can simultaneously measure the breast-height diameter and the ground diameter of the mangrove plant through the upper vernier caliper and the lower vernier caliper which are parallel with each other. When measurement by working personnel is not required, the upper vernier caliper and the lower vernier caliper can be detached for using the supporting rod as a crutch. The portable tool facilitates carrying and causes higher speed in measuring the dimensions of the breast-height diameter and the ground diameter of the mangrove plant. The portable tool provided by the utility model is used for the field of the measuring tool.

Technical field
The utility model relates to a kind of portable type measuring field of tool, particularly relates to the portable dam that a Plants diameter of a cross-section of a tree trunk 1.3 meters above the ground and leading thread are measured.
Background technology
Mangrove is the xylophyta that a class is grown in the torrid zone, seashore mesolittoral zone, subtropics, and that its growing environment has is hot and humid, stormy waves is large, radiation is strong, the soil oxygen level is low and the salinity high.Mangrove is one of first important producer of seashore and wetlands ecosystems.The biological species in forest zone is various, and the other biological in mangrove and forest zone and abiotic environment have formed a distinctive mangrove ecosystem.
Mangrove be richly stored with species diversity and living resources, the root system of mangrove is very flourishing, can be windproof, dyke strengthening, alleviate coastal disaster, be natural protective coast-forest, but the mangrove purifying sea water absorb pollutant, reduce the seawater Eutrophic Extent, prevent that red tide from occurring.Mangrove can be improved beach soil, beautifies the seashore beach environment.Mangrove ecosystem is an important subsystem of wetlands ecosystems, and is the highest system of ecologic niche level in the Wetland classification of salt water shallow sea, therefore, in order to protect and maintain ecosystem balance and the effect of mangrove, great to the Research Significance of mangrove.
In mangrove research, the researchist often need to be measured the basic growth parameter(s) of mangrove, and the diameter of a cross-section of a tree trunk 1.3 meters above the ground and leading thread are very important parameters.Because the mangrove height of tree is all shorter for land plant, when the researchist uses tape measure commonly used or tape measure to be measured in mangrove trunk section, regular bending over, very inconvenient.In addition, what with tape measure or tape measure, record is girth, also will convert, and increase the experiment difficulty, and being inconvenient to walk in mangrove inside, causes surveying work to be difficult to carry out.
The utility model content
For addressing the above problem, the utility model provides a kind of portable dam of can be more convenient the mangrove diameter of a cross-section of a tree trunk 1.3 meters above the ground and leading thread size being measured.
The utility model solves the technical scheme that its technical matters adopts:
A kind of portable dam for the mangrove diameter of a cross-section of a tree trunk 1.3 meters above the ground and leading thread measurement, comprise the support bar of vertical setting and be positioned at the support bar above and below and upper vernier caliper and lower vernier caliper parallel to each other, the top of support bar is provided with handle, and the bottom of support bar is provided with and the coaxial mounted hold-down bars of support bar.
Be further used as the improvement of technical solutions of the utility model, between the bottom of support bar and the top of hold-down bars, be provided with the round plastic sheet, the axis of support bar and hold-down bars is positioned at the center of circle of round plastic sheet.
Be further used as the improvement of technical solutions of the utility model, the overall length of support bar is 140cm, and the distance between upper vernier caliper and lower vernier caliper is 110cm, and the minor increment of the upper vernier caliper of handle distance is 10cm.
Be further used as the improvement of technical solutions of the utility model, the diameter of round plastic sheet is 15cm, and thickness is 5mm.
Be further used as the improvement of technical solutions of the utility model, hold-down bars is the pointed rod iron be connected with the bottom thread of support bar, and the diameter of hold-down bars is 2cm, and the length of hold-down bars is 15cm.
The beneficial effects of the utility model: this portable dam for the mangrove diameter of a cross-section of a tree trunk 1.3 meters above the ground and leading thread measurement can be measured the diameter of a cross-section of a tree trunk 1.3 meters above the ground and the leading thread of mangrove by upper vernier caliper parallel to each other and lower vernier caliper simultaneously, the staff when being measured, can pull down upstream mark slide calliper rule, lower vernier caliper is used support bar as crutch, this instrument is convenient for carrying, and makes the measurement of the mangrove diameter of a cross-section of a tree trunk 1.3 meters above the ground and leading thread size more quick.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model embodiment one-piece construction schematic diagram.
Embodiment
With reference to Fig. 1, the utility model is a kind of portable dam for the mangrove diameter of a cross-section of a tree trunk 1.3 meters above the ground and leading thread measurement, comprise the support bar 1 of vertical setting and be positioned at support bar 1 above and below and upper vernier caliper 2 and lower vernier caliper 3 parallel to each other, the top of support bar 1 is provided with handle 4, and the bottom of support bar 1 is provided with and the coaxial mounted hold-down bars 5 of support bar 1.
This portable dam for the mangrove diameter of a cross-section of a tree trunk 1.3 meters above the ground and leading thread measurement can be measured by the diameter of a cross-section of a tree trunk 1.3 meters above the ground and the leading thread of upper vernier caliper 2 parallel to each other and 3 pairs of mangroves of lower vernier caliper simultaneously, the staff when being measured, can pull down upstream mark slide calliper rule 2, lower vernier caliper 3 is used support bar 1 as crutch, handle 4 can facilitate the staff to be gripped this instrument in the process of using as crutch, this instrument is convenient for carrying, and makes the measurement of the mangrove diameter of a cross-section of a tree trunk 1.3 meters above the ground and leading thread size more quick.
