Abstract
The invention relates to a portable type zenith perpendicular instrument. The portable type zenith perpendicular instrument comprises a shell, a transparent cover, a floater, a pointer, an embedded base, a laser transmitter and a laser transmitter switch, wherein the instrument pointer is a transparent medium and light can pass through the pointer; the instrument shell is internally fully filled with liquid; the bottom of the pointer is embedded on the base and can rotate freely; one floater is arranged at the upper part of the pointer and the pointer can point to the zenith by using a buoyancy force principle. The angle of the instrument is adjusted through the transparent cover at the top of an observation instrument so that the pointer is overlapped with the center of the transparent cover; the laser transmitter switch is pressed and light beams are projected to the zenith position through the pointer by the laser transmitter at the bottom, namely the zenith position of the place is obtained. The portable type zenith perpendicular instrument can be used for rapidly and accurately determining the position of the zenith.
Description
Technical field
The present invention relates to portable zenith vertical collimator, be applicable to, in forest survey (experiment) process, determine the zenith point position of observation station.
Background technology
In forest survey (experiment) process, usually need the data such as projector distance, projected area measuring branch or tree crown, due in measuring process, observer is difficult to the position determining zenith point, and therefore the error of measurement data is very large, has a strong impact on the quality of data.And presently used spirit-leveling instrument, the equipment such as plumb aligner are suitable for horizontal survey and towards the vertical survey on ground, and the location for vertical zenith point then cannot be accomplished.
Summary of the invention
The demand of zenith point perpendicular positioning cannot be met, special this portable zenith vertical collimator of invention based on above-mentioned spirit-leveling instrument, plumb aligner.
The present invention relates to a kind of portable zenith vertical collimator, comprising: shell, translucent cover, float, pointer, inlaying base, generating laser, generating laser switch.
Instrument internal is full of liquid, and pointer entirety is transparent slender column; Be a spherosome bottom pointer, sphere diameter is greater than cylinder diameter, is embedded in inlaying base, and bottom can flexible rotating; Pointer middle and upper part secures a float, and under buoyancy, zenith is pointed on pointer top.
Instrument tip is a translucent cover, can be observed the position of pointer by translucent cover, and when the annulus of pointer with the center on translucent cover overlaps, pointed is zenith point.
Light source and the conllinear when pointer overlaps with translucent cover center circle of the generating laser of instrument bottom.
Generating laser switch on pressing instrument, the laser beam that generating laser produces is gone out by pointer transmission, and light is vertical with zenith, and the position that light is irradiated to is exactly the zenith point of this ground location.
Laser beam, by generating laser switch control rule, can prevent laser beam from causing unnecessary injury to human body.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is structural drawing of the present invention.
Fig. 2 is the vertical view of translucent cover.
In figure: 1 shell, 2 translucent covers, 3 floats, 4 pointers, 5 inlaying bases, 6 generating lasers, 7 generating laser switches.
Embodiment
As shown in Fig. 1, Fig. 2, portable zenith vertical collimator, by shell (1), translucent cover (2), float (3), pointer (4), inlaying base (5), generating laser (6), generating laser switch (7) is formed.
When positioning with this portable zenith vertical collimator, first determine the place that will position; Then one holds instrument, makes instrument be in plumbness; Observe the position relationship of pointer and translucent cover center circle, conditioning instrumentation, makes pointer overlap with center circle; Next step presses with finger generating laser switch, and laser beam penetrates; According to the position of laser beam irradiation, Level tune instrument, finds the position needing to carry out measuring, positions, measure.
In the process of Level tune instrument, can generating laser switch be unclamped, after finding suitable position, readjust instrument, open light source location.
