Description
Technical field
Simple trees hat width measuring instrument is the utility model is related to, it is quick to determine during forest survey (experiment)
The measuring instrument of the direction of tree crown edge-perpendicular projected position and gauger.
Background technology
In scientific research process, tree crown size and shape be study arboreal growth and Stand Growth change one it is important
Index.And the method for currently conventional measurement crown width, the east, south, west, north four that typically gauger stands under tree successively
Direction, using the method for the observation that comes back, to determine the edge of all directions tree crown;Then with tape measure tree crown edge to trunk
Distance, i.e. hat width length.This method has the following disadvantages:(1) observer, which needs to face upward head, looks up, and measures for a long time non-
It is often tired;(2) it is difficult to accomplish that visual observation position is exactly tree crown edge projection position to face upward when head is observed, and influences measurement accuracy;(3) exist
Observer is located at the more difficult determination of direction ratio of tree crown in the woods, have impact on the precision of observation.
Utility model content
1st, to solve the problems, such as
To be there is provided for there is above mentioned problem, the utility model in current trees hat width linear measure longimetry for trees hat width measurement
A kind of equipment easy to use, by the utility model can effectively solve excessive body present in trees hat width measurement process
The problems such as energy consumes, and measurement accuracy is inadequate.
2nd, technical scheme
To solve above mentioned problem present in tree crown measurement process, the utility model adopts the following technical scheme that.
A kind of simple trees hat width measuring instrument is the utility model is related to, including:Eyepiece, object lens, vertical collimator, reflex reflector lens,
Compass, handle.Eyepiece is located at objective tube lower side;It is in 45 degree of angles that reflex reflector lens, which are located at objective tube bottom with object lens bottom surface,;
Vertical collimator is located at objective tube side;Compass is located at objective lens;Handle is located at objective tube bottom.
Preferably, eyepiece is made with object lens by simple plastic material, can mitigate the overall weight of equipment, due to surveying
The height of amount is by not over 20 meters, therefore eyepiece does not need convex lens sheet to be amplified with object lens.
Preferably, for eyepiece with objective tube, respectively there is two conllinear pointed pointers near camera lens, one end is fixed on lens barrel
On, tip is on the central shaft of eyepiece and the lens barrel of object lens, and a fixed gap is left at two pointer tips, equivalent on lens
Positioning cross silk acts on, and this method simple structure, is easy to observe, and do not influence to use accuracy.
Preferably, reflex reflector lens are located at objective tube bottom, in 45 degree of angles, tilt reflective surface towards eyepiece, do not select at this
Rhizoma Sparganii reflective mirror, it is to mitigate the weight of equipment as far as possible.
Preferably, vertical collimator is located at objective tube side, is made up of all-transparent moulding material, lays the objective tube side of vertical collimator
There is a vertical slit, vertical collimator side has one to be fixed with knob, vertical collimator can be fixed in objective tube by knob
On wall, and it can ensure that vertical collimator is parallel with objective tube.Vertical slit allows the upper and lower adjusting position of vertical collimator, so can be with
The vertical hammer in vertical collimator can be seen by meeting the operator of different eyesights, and slit can play the work to lens barrel light filling
With.
Preferably, perfusion oily colourless liquid inside vertical collimator, can play stabilization to the vertical hammer in vertical collimator, can
To accelerate the perpendicular positioning time.
Preferably, compass is located at objective lens, when carrying out positioning measurement using instrument, can be determined with compass
The orientation of position.It is easy to the convenient east, south, west, north direction tree crown position for determining trees.
Preferably, handle is located at the projected position of the middle part, i.e. tree crown edge of objective tube bottom, hand when being convenient for measuring
Holding equipment, and tree crown marginal position is determined when conveniently measuring.
Preferably, whole equipment housing uses light plastic material, and simple in construction compact, can mitigate long-term measurement
When working strength, and be easy to carry.
3rd, beneficial effect
Simple trees hat width measuring instrument provided by the utility model, its advantage are:
(1) vertical collimator, corner cube mirror, compass are combined together, formed by this equipment with most simplified rational structure
One organic whole.
(2) this equipment forms housing using light material plastics, the mitigation weight of equipment that can be tried one's best;And structure is small
Ingeniously, it is easy to carry.The structure of small volume and less weight can effectively mitigate the labor intensity of user.
(3) compass structure is incorporated in a device, can quickly determine the east, south, west, north direction of hat width, improves measurement
The degree of accuracy and efficiency.
(4) vertical collimator can carry out height regulation according to operator's eyesight is horizontal, can meet different operators, and
Slit can carry out light filling to device interior, improve the definition of observation.
Brief description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the utility model structure diagram.
In figure:1 eyepiece, 2 object lens, 3 vertical collimators, 4 reflex reflector lens, 5 compasses, 6 handles.
Embodiment
As shown in figure 1, simple trees hat width measuring instrument is by eyepiece (1), and object lens (2), vertical collimator (3), reflex reflector lens (4),
Compass (5), handle (6) form overall.
When set tree crown measurement using simple trees hat width measuring instrument, the first step, the knob on vertical collimator (3) is utilized to adjust
The height of vertical collimator (3) is saved, to adapt to the vertical hammer that observer can be in vertical collimator (3) visible in detail;Second step, observer
The general edge of tree crown is gone to, at this moment first equipment can maintain an equal level, observer's compass (6) from object lens (2) top
Point to, determine the orientation of observer and measured tree;3rd step, observer stand towards with tree crown edge direction tangential, held
Handle (6), an eyes find tree crown edge by eyepiece (1), and observer suitably moves the position of standing, and adjustment equipment,
Make vertical collimator (3) vertical centering, and between making the space for the pointer that tree crown edge is located at eyepiece (1) and object lens (2), pass through mesh
Mirror (1) observation compass (5) points to, and makees appropriate location regulation;4th step, after position determines, observer can be with steel
Tape measure or other measuring apparatus carry out hat width linear measure longimetry, and the position of handle (6) is the marginal position of hat width.Repeat above-mentioned
Second step to the 4th step can be carried out continuously crown width measurement.
