Description
Technical field
The present invention relates to a kind of portable observation equipment, particularly a kind of north arrow realizing accurately measuring orientation, horizontal alignment and meet round-the-clock request for utilization.
Background technology
General north arrow is primarily of compass combination, mileage system and milimeter scale composition, can realize measuring orientation, measure in kind or pitch angle on the spot, measure curve mileage between map any two points and air line distance, estimation distance and measure general object length function on the spot, but without Ci Zuo drift angle mechanism, magnetic declination numerical value can not be ignored during measurement of bearing, therefore increase measurement of bearing error, can not adjustment level and night can not interpretation orientation.
Summary of the invention
The present invention is for solving above-mentioned deficiency, and special proposition is a kind of to revolve the multifunctional military north arrow reading formula aperiodic compass.Its basic function utilizes magnetic field of the earth to act on, and do not affect the northern orientation of instruction by Time and place, it must coordinate map to seek relative position could understand the position oneself be in.
North arrow of the present invention comprises: compass combination 1, on the spot Distance estimation mechanism 2, mileage system (containing its transmission gear and mileage indication mechanism) 3, milimeter scale 4, grade rod 5, air level 6, acupuncture treatment hole 7 and engineer's scale 8, north arrow housing comprises cap 17 and body 18, the side of cap 17 and the side of body 18 are coupled together by pin, cap can rotate around pin, covers on body;
Described compass combination 1 is connected by screw and is fixed in body 18, mileage system 3 is connected by screw and is fixed on cap 17 inside, air level 6 is connected on body 18 by gluing, milimeter scale 4 is fixed on the lower edges of cap 17, grade rod 5, acupuncture treatment hole 7 and engineer's scale 8 are fixed on body 18 by casting and machining, grade rod 5 is distributed in the inner two sides up and down of north arrow body, and acupuncture treatment hole 7 and engineer's scale 8 are distributed in the inner end angle place of body; Distance estimation mechanism 2 is made up of the connecting line aiming at breach 19 center line and foresight breach 20 center line on the spot, and aim at breach 19 and be fixed on body 18 side relative with pin, foresight breach is fixed on cap 17 side relative with pin;
Described mileage system comprises gear and gear cap 16, and containing mileage wheel 15 in gear, other gears wherein except mileage wheel 15 are covered by gear cap 16.When adopt three grades of spur gear transmissions according to transmission, mileage wheel rotates and drives indicator to make circular-rotation on disk;
Described compass combination comprises group 12 at the bottom of needle 9, bearing pack 10, compass lid 11, compass, Ci Zuo drift angle mechanism 13, pitching pendulum 14, needle 9, compass lid 11 are fixed in group 12 at the bottom of compass, at the bottom of compass lid and compass the internal cavities that group is formed axis on be provided with bearing pack 10, bearing pack 10 is riveted and is coordinated the mode of viscose glue to be fixed on above group 12 at the bottom of compass, needle 9 is arranged on bearing pack top, pitching pendulum 14 is arranged in the middle part of bearing pack, and it is inner that Ci Zuo drift angle mechanism 13 is arranged on group 12 at the bottom of compass.
Utilize magnetic field of the earth to act on, when needle is static, the North points to the magnetic north direction of the earth, now north arrow and map is together rotated, and directional arrow and needle the North is pointed to identical and parallel, is map orientation and measurement map orientation.Distance estimation is according to the similar triangle theory in number system on the spot, namely the ratio aiming at breach, the wire length of foresight breach and two lattice scribe length of foresight indentation, there is 100:1, measure arbitrary size B(of known testee as the length of object), according to formulae discovery target range L:
.Naked eyes are by aiming at breach and the run-home of foresight breach, and make to overlap with indentation, there white line, when needle is static, the North indication orientation is orientation on the spot.Milimeter scale is rule, can directly measure object length.Grade rod is according to the level line density of 1:50000 map, and measurement range is 1
o~ 30
o, the contour interval of 1:50000 military map is 10m, and isocontour spacing is A, according to formula A=(10m/tan α) ×
calculate the spacing of grade rod, therefore directly can measure the gradient of map.Engineer's scale marks according to the square rid side length of 1:25000,1:50000 map, starting point acupuncture treatment hole, directly measurement 2 between air line distance.Mileage system is made up of journey indicator and each gear etc., and mileage wheel scrolling bands traverse indicator on map rotates, and according to transmission when mileage precision determination mileage wheel diameter, therefore directly can measure the curve mileage of map.By aiming at breach and the run-home of foresight breach, check that pitching pendulum arrow indication scale is target pitch angular measurement by reflective mirror.Delimit territory, sector coverage area angle and known standpoint and impact point, with engineer's scale limit for diameter draws circular arc, can determine to bombard beaten scope, be equivalent to protractor.
North arrow tool of the present invention has the following advantages: improve army and reflect ability fast, reduce measurement of bearing error, function is more complete, and accommodation is wider.
1, resistance to low temperature is strengthened:revolve and read formula damping fluid compass, compass combination shell adopts special organic glass, adopts 3# glue bonding, and compass inside makes compass normally can use at-40 DEG C ~+55 DEG C environment by vacuumizing, injecting the operation such as damping fluid, sealing.
2, compass azimuth pointing accuracy is improved:
Housing ensures " sight alignment " when machining, and namely 3 aimed at breach, luminous ring recess, foresight breach.At the bottom of needle, bearing pack and compass, group adopts unique fit mode, and north arrow is placed in the horizontal plane, and needle group is rotated flexibly, stablized, and the red line of compass overlaps with housing " sight alignment ", and the precision of compass can reach 10 mils namely about 0.6 °.
3, newly-increased magnetic sits drift angle governor motion:calibrate according to the magnetic declination of each department or map subscript magnetic declination, make measurement of bearing more accurate.
4, use night:luminous mark on housing and compass uses the "dead" luminescent material of novel energy-storing, light source is approached compass and irradiates about 1 minute, withdraw from 1 hour after light source and can see orientation reading clearly.Irradiate 20 minutes, magnetic north can be distinguished in 8 hours.Night can normally use, and improves army's night operations ability.
5, horizontal calibrating device set up by north arrow.Launched to place in the plane by north arrow, air level is placed in the middle, can carry out adjustment level.
6, add the isocontour gradient can directly measured on map, improve army and to fight fast reaction capacity.
