Description
Technical field
A kind of measuring instrument is the utility model is related to, can especially measure a kind of polar coordinates type of irregular land area
Irregular soil instrument for measuring and calculating.
Background technology
At present in vast rural area, it is sometimes desirable to land area is measured, and the shape in plot is often irregular,
Conventional method is that plot is divided into multiple regular shapes, measures the length of side in each regular plot, then calculates area,
Every piece of area is summed up, the method wastes time and energy.Also the method for satellite fix can be used to measure, but the method is set
Standby price is higher, and measurement accuracy is not also high sometimes.
The content of the invention
Above-mentioned to solve the problems, such as, the utility model provides a kind of irregular soil instrument for measuring and calculating of polar coordinates type.This pole is sat
The irregular soil instrument for measuring and calculating of mark formula can use the area in the irregular soil of polar coordinates principle measurement.
Technical scheme is used by the utility model solves technical problem：A kind of irregular soil of polar coordinates type is invented to survey
Instrument is calculated, is characterized in, the irregular soil instrument for measuring and calculating of polar coordinates type has a base, and three legs are uniformly installed around base bottom
, leg is hinged in stand bar seat, two worm brackets are installed in base bottom, and worm screw is installed by bearing between two worm brackets,
Handwheel is installed in one end of worm shaft, pointer is installed on handwheel, dial is installed on the worm bracket of installation handwheel side, the bottom of at
Installation worm-wheel shaft among seat, worm gear is installed in worm-wheel shaft lower end, worm gear and worm screw are meshed, and installation turns in the upper end of worm-wheel shaft
Disk, pass through fixed mount fixed laser rangefinder on rotating disk.
The beneficial effects of the utility model are that the utility model is used for the area for measuring irregular soil, and cost is low, work
Intensity is small, and the utility model is simple in construction, light and flexible.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Accompanying drawing is the front view of the present embodiment.
1 leg in figure, 2 handwheels, 3 stand bar seat, 4 bases, 5 pointers, 6 dials, 7 worm screws, 8 worm brackets, 9 worm-wheel shafts, 10
Rotating disk, 11 fixed mounts, 12 laser range finders, 13 worm gears, 14 lock-screws.
Embodiment
As shown in drawings, three stand bar seat 3 are uniformly installed around the bottom of base 4, leg 1, base 4 are hinged in stand bar seat 3
Two worm brackets 8 are installed in bottom, and worm screw 7 is installed by bearing between two worm brackets 8, and hand is installed in one end of the axle of worm screw 7
2 are taken turns, pointer 5 is installed on handwheel 2, dial 6 is installed on the worm bracket 8 of installation handwheel 2 side, snail is installed among base 4
Wheel shaft 9, worm gear 13 is installed in the lower end of worm-wheel shaft 9, worm gear 13 and worm screw 7 are meshed, and rotating disk 10 is installed in the upper end of worm-wheel shaft 9,
Pass through the fixed laser rangefinder 12 of fixed mount 11 on rotating disk 10.
As shown in drawings, the utility model is placed on during use the centre position of institute's geodesic block, leg 1 is supported on ground
On, make base 4 parallel with ground, a people takes a reflector, stands on some position of the edge of institute's geodesic block, erects reflective
Plate, it is allowed to, towards the utility model, open laser range finder 12, rotates handwheel 2, handwheel 2 drives worm screw 7 to rotate, and worm screw 7 drives
Worm gear 13, worm gear 13 drive worm-wheel shaft 9, and worm-wheel shaft 9 drives rotating disk 10, and rotating disk 10 drives laser range finder 12 to rotate, makes laser
The camera lens face reflector of rangefinder 12, laser range finder 12 stop operating when being connected to return signal, now unclamp lock-screw 14
Rotary dial 6, the zero point of dial 6 is directed at pointer 5, screw lock-screw 14, fixed dial 6, record Laser Measuring
Distance measured by distance meter 12, edge of the reflector along institute's geodesic block is moved into one section of distance close to straight line, rotate handwheel 2 and drive
It is dynamic to rotate laser range finder 12, make the camera lens face reflector of laser range finder 12, again measurement distance, and noting down, handwheel 2
Drive pointer 5 to rotate, the angle that laser range finder 12 is turned over can be read on dial 6, and note down, reflector stops
Two points and the utility model where point form a triangle, two length of sides of this triangle have measured, and measure
The angle on two sides, the area of the triangle can be calculated by surveyed data, method is around the side of institute's geodesic block according to this
Edge measures one week, can obtain the area of multiple triangles.Finally the area of all triangles is added and can try to achieve entire area
Area.
