Abstract
The utility model discloses a spring latch type portable tree height measuring tool. The spring latch type portable tree height measuring tool comprises a telescopic rod formed by sequentially connecting a plurality of mutually-nested tube members with different diameters in a diameter decreasing mode, wherein each of nested-connection portions of the tube members is provided with a lock catch used for keeping the telescopic rod in a straight state, and the tube members are marked with scales. When the spring latch type portable tree height measuring tool is used for measuring tree height, the telescopic rod formed by sequentially connecting a plurality of mutually-nested tube members is fixed by the lock catches to stay in an extension state and is placed beside a mangrove plant, height of the mangrove plant can be obtained by directly reading scales on the tube members, operation is simple and fast, after measurement, the telescopic rod can be folded into one with length of one single tube member, reduces an occupation space and is portable. The spring latch type portable tree height measuring tool belongs to the technical field of measuring tools.
Description
Technical field
the utility model relates to measuring appliance, particularly a kind of survey instrument of the height of tree for mangrove.
Background technology
mangrove is the xylophyta that a class is grown in the torrid zone, seashore mesolittoral zone, subtropics, and that its habitat 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 river 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, and be natural protective coast-forest; But the mangrove purifying sea water, absorb pollutant, reduces 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 height of tree is a very important parameter.Due to the singularity of mangrove modes of reproduction, plumular axis interpolation randomness is larger, and is distributed in around parent more, causes mangrove density too high, the growth of trees intersection.The researchist can't use land plant to survey high instrument and in place far away, mangrove be measured, and being inconvenient to walk in mangrove inside, causes surveying work to be difficult to carry out.So a kind of invention for the portable dam of measuring the mangrove height of tree is extremely urgent.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of portable height of tree survey instrument of night bolt formula that can conveniently in Mangrove Wetlands, carry out height of tree surveying work.
For solving the problems of the technologies described above adopted technical scheme: the portable height of tree survey instrument of a kind of night bolt formula, comprise that the pipe fitting different by some diameter is by the diameter mutually nested telescoping rod connected and composed successively from big to small, be provided with the fixed fitting position so that the snap close of telescoping rod in extended configuration is labeled with scale value on pipe fitting in the nested junction of each pipe fitting.
Be further used as the improvement of technical solutions of the utility model, in the nested junction of adjacent pipe fitting, have corresponding through hole, snap close comprises that the latch and the end that snap in through hole are fixed in the spring in pipe fitting, and the other end of spring is fixedly connected with the latch bottom.
Be further used as the improvement of technical solutions of the utility model, at telescoping rod one end, be connected with wrist strap.
Be further used as the improvement of technical solutions of the utility model, pipe fitting is stainless-steel tube.
Beneficial effect: while utilizing the portable height of tree survey instrument of this night bolt formula to carry out height of tree surveying work, to be fixed into extended configuration by the mutually nested telescoping rod connected and composed of pipe fitting by snap close is positioned over by mangrove, the height of tree of directly by the upper scale value of pipe fitting, reading mangrove, simple and quick, after measurement completes, telescoping rod is retracted to the length of single pipe fitting, reduces and takes up an area space, is convenient for carrying.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further;
The structural representation that Fig. 1 is the utility model embodiment;
The structural representation that Fig. 2 is snap close in the utility model embodiment.
Embodiment
See figures.1.and.2, the portable height of tree survey instrument of a kind of night bolt formula of the utility model, comprise that the pipe fitting different by some diameter 11 is by the diameter mutually nested telescoping rod connected and composed 10 successively from big to small, be provided with fixed fitting 11 positions so that the snap close 20 of telescoping rod 10 in extended configuration is labeled with scale value on pipe fitting 11 in each nested junction of pipe fitting 11.
While utilizing the portable height of tree survey instrument of this night bolt formula to carry out height of tree surveying work, to be fixed into extended configuration by the mutually nested telescoping rod connected and composed 10 of pipe fitting 11 by snap close 20 is positioned over by mangrove, the height of tree of directly by the upper scale value of pipe fitting 11, reading mangrove, simple and quick, after measurement completes, telescoping rod 10 is retracted to the length of single pipe fitting 11, reduces and takes up an area space, is convenient for carrying.Telescoping rod 10 is telescopic type, length and weight all, much smaller than other common height of tree survey instrument, do not take larger space during placement, reduced to carry difficulty, realize the Mangrove Wetlands measurement height of tree larger in plant growth density, improved the high efficiency of investigation surveying work.
As the utility model preferred implementation, have corresponding through hole in the nested junction of adjacent pipe fitting 11, snap close 20 comprises that the latch 21 and the end that snap in through hole are fixed in the spring 22 in pipe fitting 11, the other end of spring 22 is fixedly connected with latch 21 bottoms.
As the utility model preferred implementation, at telescoping rod 10 1 ends, be connected with wrist strap 12.
Can save by wrist strap 12 is set the casing that holds other common height of tree survey instrument, reduced transportation and carried difficulty, more be conducive to field study.
As the utility model preferred implementation, pipe fitting 11 is stainless-steel tube.
The above is explained in detail embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned embodiment, in the ken possessed at described technical field those of ordinary skill, can also under the prerequisite that does not break away from the utility model aim, make various variations.
