Abstract
First horizontal range must be measured before solving the measurement trees on market, add labour intensity, efficiency is low, and survey instrument carries the problem of inconvenience, a kind of instrument for estimating the height of tree fast of special proposition, comprises cross bar and montant, it is characterized in that: cross bar is vertical with montant to be arranged, formed T-shaped, and montant can move vertically along cross bar; Wherein, montant is arranged using centimetre as the scale of unit, cross bar arranges datum line; The length of montant and cross bar all preferably chooses 25cm; This instrument not only makes simply, and labour intensity is low, and efficiency is high, and can Portable light, easy to use.
Description
Technical field
The utility model relates to measuring appliance, especially a kind of instrument for estimating the height of tree fast.
Technical background
In forest inventory investigation, the height of tree is important observation index.Adopt height finder to measure the height of tree time most of, can carry, measuring accuracy also can meet the needs of most of Forestry Investigation, but requires first to measure horizontal range before the height surveying every strain trees, and add labour intensity, efficiency is low; And " method for fast measuring of every wood location standing forest height of tree " of the patent No. 201310373825.3 is the coordinates being obtained each strain Dan Mu in woods by location instrument, look for a strain can see single wood of measuring object measure its to measuring object the highest the elevation angle and the angle of depression of minimum point, two strain tree horizontal ranges are calculated according to coordinate, the calculation height of tree is asked again with trigonometric function, then do not need to remeasure horizontal range again after known every wooden locator data, though the efficiency of improve, survey instrument carries inconvenience.
Summary of the invention
First must measure horizontal range before solving the measurement trees on market, add labour intensity, efficiency is low, and survey instrument carries inconvenient problem, a kind of instrument for estimating the height of tree fast of special proposition, this tool making is simple, efficiency is high, and Portable light, easy to use.
For estimating an instrument for the height of tree fast, comprising cross bar and montant, it is characterized in that: cross bar is vertical with montant to be arranged, and formed T-shaped, and montant can move vertically along cross bar; Wherein, montant is arranged using centimetre as the scale of unit, cross bar arranges datum line; The length of montant and cross bar all preferentially chooses 25cm.
The material of described cross bar and montant is preferably iron.
The beneficial effects of the utility model: this instrument not only makes simply, and labour intensity is low, and efficiency is high, and can Portable light, easy to use.

Embodiment
Embodiment 1: as shown in Figure 1, a kind of instrument for estimating the height of tree fast, comprise cross bar 1 and montant 2, it is characterized in that: cross bar 1 is vertical with montant 2 to be arranged, and is formed T-shaped, the one end being provided with datum line 4 at cross bar 1 arranges square external member 3, montant 2 is enclosed within square external member 3, square external member 3 center is provided with perspective mouth 6, can see the datum line 4 on cross bar 1 and the scale on corresponding montant 2 in use, montant 2 can move vertically along cross bar 1; Wherein, montant 2 is arranged using centimetre as the scale of unit, the material of cross bar 1 and montant 2 is iron, and the length of montant 2 and cross bar 1 is 25cm.
Embodiment 2: as shown in Figure 2, a kind of instrument for estimating the height of tree fast, comprise cross bar 1 and montant 2, it is characterized in that: cross bar 1 is vertical with montant 2 to be arranged, formed T-shaped, the one end being provided with datum line 4 at cross bar 1 arranges slide block 5, and montant 2 center is provided with opening 7, slide block 5 is placed on montant 2 by opening 7, and montant 2 can move vertically along cross bar 1; Wherein, montant 2 is arranged using centimetre as the scale of unit, the material of cross bar 1 and montant 2 is iron, and the length of montant 2 and cross bar 1 is 25cm.
As Fig. 2, shown in 3, during work, first people stand in can the place of the substantially visual estimation height of tree, the position being placed on people's nose with the O point of T-shaped instrument is motionless, then the montant 2 on T-shaped instrument is moved up and down, the point of the c on montant 2 (0cm scale mark) is made to be on sight line OC, b point on datum line 4 is on OB, BC is then for people's pin when people's pin and tree root are in same level is to the distance of datum line 4, because the cross bar 1 of T-shaped instrument is perpendicular to nose, with plane-parallel, montant 2 and trunk are all perpendicular to surface level, montant 2 is parallel with trunk, at this moment, sight line OC is the height A C of trees at the reading at the intersection point c place of T-shaped instrument montant 2, it can thus be appreciated that: △ Obc ∽ △ OBC, △ Oac ∽ △ OAC sets up, and can be obtained by similar triangles theorem: bc: BC=Oc: OC, ac: AC=Oc: OC, inference obtains: bc: BC=ac: AC.
The above is embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
Claims (2)
