Abstract
" no scaleplate " measuring apparatus: belong to field of measuring technique, solve the technology of measuring without scale.
Major technique feature and purposes: (1) is to design according to the anti-theorem of looking, and playing can be distance and the effect of highly measuring without scale; (2) by mark post index glass and survey mirror are connected into absolute altitude (the index mirror center is to the mirror test center), the three forms a whole, and plays the effect (accompanying drawing 2) of " moving the anti-chi of mark " during measurement; (3) in the survey mirror one of delineation plate is housed, plays the effect (accompanying drawing 3) that the anti-apparent value of testee is shown; (4) by changeing, play the high effect of surveying than transferring the outer high denominator of survey of carving to surveying high denominator interior quarter.
Description
" no scaleplate " measuring apparatus belongs to field of measuring technique.
" no scaleplate " measuring apparatus is an instrument that does not also have in the world.
Invention is for without tape measure, reaches people from province saving of work and time purpose accurately.
The content of " no scaleplate " measuring apparatus:
One, the anti-theorem of looking
The anti-theorem of looking is according to seeing closely and see far, seeing height and see that short Changing Pattern finds out.
Theorem one:
When object height was constant, anti-apparent value was inversely proportional to distance, and (promptly distance is long more, and anti-apparent value is more little; Distance is short more, and anti-apparent value is big more).The multiple that the anti-apparent value of one meter distance of ratio dwindles equals distance.
Theorem two:
When distance when constant, anti-apparent value with highly be directly proportional.(be that object is high more, anti-apparent value is big more; Object is short more, and anti-apparent value is more little), the multiple that increases than the anti-apparent value of one meter height equals height.
Conclusion:
(1) according to theorem one, the object of certain altitude, the anti-apparent value on one meter distance and position (by constant) be range finding from molecule, at any locational anti-apparent value, be range finding from denominator.
(2) according to theorem two, object is the high molecule of surveying at any one locational anti-apparent value of straight line (being called for short high value), and the anti-apparent value of one meter height (being called for short the anti-apparent value of rice) is the high denominator of surveying.
Two, structure and purposes
(1) structure
" no scaleplate " measuring apparatus by index glass, survey mirror, mark post, quarter chi, vertical angle scale, compass, tripod etc. seven and partly form (accompanying drawing 1).
(2) purposes
Index glass-be used to look for measuring point and move mark cooperates with the survey mirror, and the absolute altitude on the instrument is moved on on the testee.
Survey dress in mirror-surveys mirror with one of the equidistant optical glass delineation plate of scale in length and breadth, by object lens the height of mark or object is refracted to survey in the mirror and delineates on the plate, show anti-apparent value data.From anti-apparent value data, calculate distance and height.
Mark post-connect index glasses and survey mirror by one or two mark posts, and to make two mirrors become absolute vertical to form a whole, index glass center to mirror test center is called absolute altitude, uses as measuring.
Carve vertical one of the chi of carving of chi-survey mirror installation outward, survey height by changeing than (promptly survey high denominator interior quarter and transfer the outer high denominator ratio of survey of carving to).
The vertical angle scale-being used for inclined range changes horizontal range and surveys the mountain height.
Compass-be used to survey area.
Tripod-be used to set up instrument.
Three, measuring method
(1) range finding from: with index glass centrally aligned measuring point, maintain static, write down survey the measuring point that demonstrates on the vertical groove in the mirror to the scale (being anti-apparent value) of mirror test center,
Formula 1: distance=(constant)/(anti-apparent value)
(2) survey height: get anti-apparent value with telemetry earlier, and remembered angle.Take advantage of mark to equal rice anti-apparent value (promptly surveying high denominator) with anti-apparent value again than (seeing that mark is than table).See again and survey the interior testee pin of mirror to the scale between the top (promptly high value).
Formula 2: highly=(high value)/(surveying high denominator * angle) than (seeing that the angle is than table)
The not enough high time spent of survey of scale in surveying mirror, just survey height with carving chi, its method is: must survey high denominator with surveying high method earlier, And has remembered angle; Aim at the bottom of measured object again with the mirror test center, see and survey the outer red line of mirror and carve chi intersection point place scale (be called for short down and carve); Again the mirror test center is aimed at the top of measured object, the same intersection point place scale (carving on the abbreviation) that gets, the difference of scale equals high quarter (promptly high value) up and down.
Formula 3: highly=(high value)/(surveying high denominator * angle ratio * commentaries on classics ratio)
Change than promptly surveying high denominator interior quarter and transfer outer ratio (being exemplified below table) of carving the high denominator of survey to
" no scaleplate " measuring apparatus is compared with existing surveying instrument: " no scaleplate " measuring apparatus is not only without scale, and have in light weight, volume is little, calculate simple advantage, reach people from province, saving of labor, save time, purpose accurately, and remedying existing instrument can't measure, equally the characteristics that can measure.
" no scaleplate " measuring apparatus (WC-III type) is now trial-produceed successfully.And has finished writing one of operation instructions, and on probation by departments such as forestry, water conservancy, post and telecommunications, degree of accuracy is all more than 99 percent.
Accompanying drawing 1(" no scaleplate " measuring apparatus synoptic diagram): each toponym of instrument: 1. the nut of focusing; 2. survey mirror; Quarter chi; 4. vertical angle scale; 5. universal nut; 6. horizontal steering wheel; 7. mark post; 8. index glass; 9. tressel; 10. lock-screw; 11. micrometer adjusting screw; 12. compass; 13. horizontal screw; 14. trip bolt.
Accompanying drawing 2:1. moves mark: AB is an absolute altitude.A ' B ' is that index glass and survey mirror move on to absolute altitude on the tested object.2. anti-chi: an object A ' backspace is refracted on the delineation plate to object lens by focal point F, demonstrates anti-apparent value.
Accompanying drawing 3:1. is delineation plate (packs into and survey in the mirror);
2. be graticule (in the index glass of packing into).
Claims (3)
1, " no scaleplate " measuring apparatus, this installs useful pole or other method of attachment [accompanying drawing 1 (7)] and perpendicular to index glass [accompanying drawing 1 (8)] with survey mirror [accompanying drawing 1 (2)].The left side or the right vertically are equipped with and are carved one of chi [accompanying drawing 1 (3)], its feature outside it surveys mirror:
