Description
Technical field
The utility model belongs to the prism used in mapping tooling technical field more particularly to a kind of tunnel and accounts for board.
Background technology
In survey field, total powerstation is to use more extensive measuring instrument, but total powerstation needs in use
Cooperation prism accounts for board and is used in conjunction with, and common total station prism accounts for board in use, it is only necessary to accounting for board and prism is fixed
It is installed on pedestal to together, adjustment accounts for after board is overlapped with prism centers line, alignment total powerstation is aimed at after leveling, centering, but complete
Instrument of standing observe prism when be switched on glare light electric torch, sight and account for board and prism, in observation process must whole process illuminate, due to rib
Mirror accounts for board triangle itself and does not shine, and sights target difficult, be easy to cause deviation.
Invention content
The purpose of this utility model is to provide the prism used in a kind of tunnel that can fast and accurately observe and accounts for board.
In order to achieve the above objectives, the technical solution adopted in the utility model is：
The prism used in a kind of tunnel accounts for board, including accounts for board, it is described account for board include the prism being located in upper body and
Centering rod positioned at prism lower part, the prism are respectively arranged on the left side and the right side symmetrical first equilateral triangle region, and first positive three
A horizontal joint bright line slot, the horizontal central line of two horizontal joint bright line slots and prism are respectively equipped in angular domain at symmetric position
It overlaps, the prism top center is set there are one the second equilateral triangle region, and one is equipped in the second equilateral triangle region vertically
Stitch bright line slot, the vertical bright line slot that stitches is overlapped with the vertical center line of prism, the prism back set there are one it is in the same size with prism
Reflector.
Further, the prism is rectangle.
Further, the reflector is liquid crystal display, and reflector is battery powered.
Further, the center line of the centering rod is overlapped with the vertical center line of prism, and the bottom of centering rod is circular cone
Shape.
Further, the length of the vertical seam bright line slot and horizontal joint bright line slot is respectively less than the height of equilateral triangle.
The utility model this have the advantage that：Since the utility model adds reflector, the light of reflector at prism rear
Line can be penetrated by horizontal joint bright line slot on prism and vertical seam bright line slot, instead of traditional artificial exterior lighting method,
And improve accuracy of observation and observation speed.

Specific implementation mode
As shown, the prism used in a kind of tunnel accounts for board, including board is accounted for, the board that accounts for includes being located in upper body
Prism 2 and centering rod 1 positioned at 2 lower part of prism, the center line of the centering rod 1 overlapped with the vertical center line 6 of prism, and it is right
The bottom of middle bar 1 is cone, and convenient for being fixed with pedestal, the prism 2 is rectangle, 2 left and right sides of the prism for setting in this way
It is respectively equipped with symmetrical first equilateral triangle region, a horizontal joint is respectively equipped at symmetric position in the first equilateral triangle region
Bright line slot 3, two horizontal joint bright line slots 3 are overlapped with the horizontal central line 5 of prism 2, and 2 top center of the prism is set there are one second
Equilateral triangle region, is equipped with a vertical seam bright line slot 4 in the second equilateral triangle region, vertical to stitch the perpendicular of bright line slot 4 and prism 2
Straight center line 6 overlaps, and the length of the vertical seam bright line slot 4 and horizontal joint bright line slot 3 is respectively less than the height of equilateral triangle, the rib
2 back of mirror set there are one with 2 reflector of the same size of prism, the reflector is liquid crystal display, and reflector supplies by battery
Electricity.
When specifically used, power supply is opened, the light on reflector passes through bright line slot, a long way off can be clear using total powerstation
It sights prism 2 and accounts for board center, make the precise alignment ranging in the weaker tunnel of light, avoid because caused by luminance shortage
Sighting mark error also saves the labour cost that manpower is sighted.
