Abstract

The utility model discloses a portable tool for height measurement of mangrove plant, which comprises a plurality of rulers that are successively hinged from head to tail. The connection part between two hinged rulers is provided with a fixing block. The side surface of each fixing block is provided with a through tank for placing the ruler. The bottom surface of the through tank is straight and furthermore two side walls are provided with plastic soft blocks which are stagger from each other and clamp the ruler. In the portable tool for height measurement of the mangrove plant, the hinged rulers can be straightened and loaded in the through tanks of the fixing blocks in use, so that the side surfaces of two rulers abut against the bottom surface of the through tank. Then two rulers are compressed on two side grooves in the through tank respectively through two plastic soft blocks, thereby ensuring high straightness in measurement. In walking, the hinged rulers can be folded and retreated. Small occupation space and high convenience in carrying are obtained. Height measurement at mangrove wetland with larger plant growth density is facilitated. Operation efficiency in investigation and measurement is improved.

Description

A kind of portable dam of measuring for the mangrove height of tree
Technical field
The utility model relates to a kind of survey instrument, particularly relates to a kind of portable dam of measuring for the mangrove height of tree.
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, and portable common folding ruler is easily crooked when measuring, and uses inconvenience.
The utility model content
For addressing the above problem, when providing a kind of the measurement, the utility model keeps the portable dam of measuring for the mangrove height of tree straight, that be convenient for carrying while walking.
The utility model solves the technical scheme that its technical matters adopts: a kind of portable dam of measuring for the mangrove height of tree, comprise some head and the tail hinged ruler in turn, every two hinged rulers are equipped with fixed block in junction, the side of fixed block is provided with the groove of placing ruler, the bottom surface of groove is straight and be provided with the plastic cement magma that mutually staggers and clamp ruler on two side, and the side of two rulers is adjacent to the bottom surface of groove.
Be further used as the improvement of technical solutions of the utility model, connect by rotatable rivet between every two hinged rulers.
Be further used as the improvement of technical solutions of the utility model, the free end of the first ruler of initiating terminal is provided with wrist strap.
Be further used as the improvement of technical solutions of the utility model, each ruler is stainless rule, and each ruler is equipped with the scale that scale division value is 1mm along its length.
The beneficial effects of the utility model: the portable dam that this is measured for the mangrove height of tree, can stretching each hinged ruler during use and the groove of the fixed block of packing in, make the side of two rulers be adjacent to the bottom surface of groove, respectively two rulers are pressed on the two side in groove by two plastic cement magmas again, keep straight while guaranteeing to measure; Ruler that can each is hinged during walking turns back and packs up, take up an area space little, be convenient for carrying, be convenient to the Mangrove Wetlands larger in plant growth density and measure the height of tree, improved the high efficiency of investigation surveying work.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the one-piece construction schematic diagram of the utility model embodiment;
Fig. 2 is the fixed-block-architecture (FBA) schematic diagram of the utility model embodiment;
Fig. 3 is the utility model embodiment ruler fixed-block-architecture (FBA) schematic diagram of packing into.
Embodiment
With reference to Fig. 1~Fig. 3, the utility model provides a kind of portable dam of measuring for the mangrove height of tree, comprise some head and the tail hinged ruler 1 in turn, every two hinged rulers 1 are equipped with fixed block 2 in junction, the side of fixed block 2 is provided with the groove 21 of placing ruler 1, and the bottom surface of groove 21 is straight and be provided with the plastic cement magma 22 that mutually staggers and clamp described ruler 1 on two side.
The portable dam that this is measured for the mangrove height of tree, can stretching each hinged ruler 1 during use, and in the groove 21 of the fixed block 2 of packing into, make the side of two rulers 1 be adjacent to the bottom surface of groove 21, by two plastic cement magmas 22, respectively two rulers 1 are pressed on the two side in groove 21 simultaneously, carry out height of tree measurement after fixedly completing, fixed block 2 plays the effect that fixedly secures ruler 1 junction, the buckling phenomenon of having avoided this portable dam of measuring for the mangrove height of tree in use often to occur, improved accuracy of measurement, in addition, plastic cement magma 22 friction factor are larger, can complete better being fixedly clamped of ruler 1.Ruler 1 that can each is hinged while carrying turns back and packs up, take up an area space little, be convenient for carrying, the utility model is convenient to the Mangrove Wetlands larger in plant growth density and is measured the height of tree, has improved the high efficiency of investigation surveying work.
As the utility model preferred embodiment, 1, every two hinged rulers connect by rotatable rivet, and rivet is connected to the preferred articulated manner of the utility model, and the mode that is articulated and connected that other are equal to all falls into protection domain of the present utility model.
As the utility model preferred embodiment, the free end of the first ruler 1 of initiating terminal is provided with wrist strap 3.
The casing that holds other common height of tree survey instrument has been saved in the setting of wrist strap 3, has reduced transportation and has carried difficulty, more is conducive to field study.
As the utility model preferred embodiment, each ruler 1 is stainless rule, and each ruler 1 is equipped with the scale that scale division value is 1mm along its length.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and the modification that these are equal to or replacement all are included in the application's claim limited range.
