Abstract
The utility model relates to an apparatus for precisely measuring tree diameter growth, which is fixedly provided with a casing tube with a certain length at one end of the an equal-width and flexible ruler which is not easy to be stretched and is labeled with scales; the casing tube or the ruler is provided with two fixing holes for fixing nails; through two nails which pass through the fixing holes, the utility model is conveniently fixed onto a tree; simultaneously, the other end of the ruler corresponding to the initial end passes through the casing tube and is tightened; the scale value of measuring the initial time is disassembled; the precise tree diameter growth can be visually represented, when the measurement is ended, and the ruler is pulled out a section of length from the casing tube. The utility model which is convenient and visual has simple structure, and precise measurement.
Description
(1), technical field
The utility model relates to a kind of device of accurate measurement trees breast diameter growth.
(2), background technology
Measure the trees diameter of a cross-section of a tree trunk 1.3 meters above the ground at present both at home and abroad two kinds of devices are arranged: the one, diameter of a cross-section of a tree trunk 1.3 meters above the ground slide calliper rule, another kind is tape measure or steel tape, the former directly measures its diameter of a cross-section of a tree trunk 1.3 meters above the ground, the latter is the band shape that indicates scale or the filiform of wide soft flexible difficult stretching usually, and they are by measuring the diameter of a cross-section of a tree trunk 1.3 meters above the ground scale that its girth is converted into the diameter of a cross-section of a tree trunk 1.3 meters above the ground or directly reads corresponding its girth of mark on the ruler.Though utilizing above two kinds of instruments measures simple, practical, accurate inadequately.Its reason is that trees diameter of a cross-section of a tree trunk 1.3 meters above the ground place generally is not accurate circle, and diameter of a cross-section of a tree trunk 1.3 meters above the ground slide calliper rule are in different orientation measurements, or inclination is arranged slightly during tape measure, will record different numerical value; In addition, if investigate the growth of trees, need repeatedly to measure.Be difficult to guarantee that with above-mentioned two kinds of methods twice measurement is to carry out at same position.Therefore, the breast diameter growth amount that two kinds of survey instruments are accurately measured trees more than is actually very difficult.
(3), summary of the invention
The utility model aims to provide a kind of device of accurate measurement trees breast diameter growth.
Technical solution of the present utility model is as follows:
A kind of device of accurate measurement trees breast diameter growth, the band shape that indicates scale or the filiform that comprise a wide flexible difficult stretching, it is characterized in that: it also comprises one section sleeve pipe of the certain-length that the initiating terminal with this band shape or filiform fixes, and the width of the width of described cannula cavity and band shape or filiform is suitable; Also have two fixed orifices that are used for fixing nail on described band shape or filiform or this sleeve pipe.
Utilizing the utility model is the breast diameter growth amount of so accurately measuring trees: by two nails that pass fixed orifice the utility model is fixed on the trees, band shape or filiform are passed or penetrate certain depth in the sleeve pipe that fixes with initiating terminal with respect to the other end of initiating terminal, tension, because the width of cannula cavity is suitable with the width of band shape or filiform, exist certain friction to guarantee that both can not unclamp voluntarily in non-external force effect between the two, write down the scale value of measuring initial time, growth along with the trees diameter of a cross-section of a tree trunk 1.3 meters above the ground, band shape or filiform produce relative displacement with respect to the other end and the sleeve pipe of initiating terminal, this shift value be exactly during this period of time in the accurate increments of trees, it shows as the segment length that band shape or filiform are pulled out in the sleeve pipe intuitively.
In the above-mentioned technical solution, the length of described sleeve pipe should be greater than 3cm to guarantee can not unclamp required friction voluntarily.
The utility model is simple in structure, measures accurately, and is convenient directly perceived.
(4) description of drawings:
Accompanying drawing 1 is the synoptic diagram of the utility model embodiment;
Accompanying drawing 2 is the synoptic diagram of the utility model embodiment;
Each sequence number is respectively among the figure: 1, steel tape, 2, sleeve pipe, 3, fixed orifice, 4, scale, 5, inner chamber
(5) embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Referring to accompanying drawing 1, the utility model embodiment by a steel tape 1 and with one of one section sleeve pipe 2 of the 20cm that fixes of end form, scale 4 is arranged on the steel tape 1, the width of the width of cannula cavity 5 and steel tape 1 is suitable, the both sides up and down of sleeve pipe 2 also have two fixed orifices 3 that are used for fixing nail, with two nails that pass fixed orifice 3 the utility model embodiment is followed closely in the tree, the other end of steel tape 1 is passed sleeve pipe 2, tension, write down the scale value of measuring initial time, behind the arboreal growth certain hour, the segment length that steel tape 1 is pulled out in the sleeve pipe
L just can obtain the accurate increment of the interior trees diameter of a cross-section of a tree trunk 1.3 meters above the ground during this period of time in view of the above.
Certainly, under inventive concept of the present utility model, the utility model has multiple form of implementation, as, for the sake of simplicity, save for the purpose of the cost, shown in embodiment 2, implement the utility model with a steel wire that curves 2-3 circle thereon, one of them circle (what internal diameter should be suitable is little) is made sleeve pipe 2 and is used for wearing steel wire, another circle hole 3 that fixes is used for nailing, and is feasible equally, and this is a kind of simple replacement scheme of the present utility model only, it is read those skilled in the art and need not pay creative work behind this instructions and can reveal again, has not just described in detail at this.
Claims (2)
1, a kind of device of accurate measurement trees breast diameter growth, the band shape that indicates scale or the filiform that comprise a wide flexible difficult stretching, it is characterized in that: it also comprises one section sleeve pipe of the certain-length that the initiating terminal with this band shape or filiform fixes, and the width of the width of described cannula cavity and band shape or filiform is suitable; Also have two fixed orifices that are used for fixing nail on described band shape or filiform or this sleeve pipe.
2, the device of accurate measurement trees breast diameter growth according to claim 1, it is characterized in that: the length of described sleeve pipe is greater than 3cm.
