Abstract
The utility model relates to a telescopic biprism for improving monitoring accuracy of mining area surface subsidence. The telescopic biprism comprises a prism I, a telescopic connecting rod, a fixed length connecting rod, a prism II and a prism rod, wherein the lower part of the outer frame of the prism I is connected with the telescopic connecting rod with scales; the telescopic connecting rod is connected with the upper part of the outer frame of the prism II through the fixed length connecting rod; the lower part of the outer frame of the prism II is downwards connected with the prism rod with the scales and a tapered bottom end. The telescopic biprism solves the technical problems that a prism rod consisting of a single prism inclines due to surface subsidence or other interference factors, so that the measurement inaccuracy of spatial position of ground measurement point is caused, satisfies the requirements for higher measurement accuracy in the severe environment, and greatly facilitates work of measurement personnel.
Description
Technical field
the utility model relates to a kind of biprism, especially a kind of scalable biprism that improves mining area surface depression monitoring accuracy.
Background technology
at present, the technology that takes measurement of an angle large group about other existing and that once had was all done very fruitful effort to the demand of prism, also once designed a lot of outstanding schemes.The utility model patent " Plumbed reflecting prism device " of declaring as Lingbao City Jinyuan Mining Co., Ltd. in 2008 and utility model patent " total station prism the group " (application number: 200920253556.6) etc., improved to a great extent measuring speed and reduced cost of Gu Shuyu application in 2009.Prism has two kinds, round prism and 360 ° of prisms, prism is also had to research abroad, such as three prism groups or nine prism groups etc. are set.But above-mentioned prism group has weak point in solving practical problems fashion, for example, while carrying out deformation monitoring on the minery earth's surface, be moved because earth's surface is subject to mining influence, sedimentation etc. changes or other extraneous factors, make mirror holder or prism bar also certain tilted deflecting may occur, now by alignment prism, ask calculation measuring point locus to there will be deviation.Be difficult to solve the technical matters that improves this one side of measuring accuracy.
The utility model content
in order to solve the existing prism group not high problem of measuring accuracy in use, the utility model provides a kind of scalable biprism that improves mining area surface depression monitoring accuracy, this scalable biprism has solved prism bar that single prism forms and has caused prism bar to tilt due to surface subsidence or other disturbing factor, thereby the technical matters that the spatial position measuring that affects the ground measuring point is inaccurate, meet the demand had than high measurement accuracy in rugged surroundings, brought very large facility to the work of survey crew.
the utility model solves the technical scheme that its technical matters adopts: this scalable biprism comprises prism I, scalable connecting link, fixed length connecting link, prism II and prism bar; The bottom of described prism I housing is connected with being with graduated scalable connecting link, and scalable connecting link is connected with the top of prism II housing by the fixed length connecting link, the prism bar that it is taper that the bottom of prism II housing is connecting with graduated bottom downwards; Described prism I and prism II are circular prism; Described prism I housing is plastic material, and the housing of prism II, scalable connecting link, fixed length connecting link and prism bar are plumbous material, not only light but also firm, adapts to the measurement demand of surveying instrument.While using this biprism to be measured, at first mirror being set high is zero, measured is respectively the volume coordinate at prism I and prism II center, read respectively length between prism I and prism II and the prism II distance to the ground measuring point by the prism bar of the accurate scale of the scalable connecting link with accurate scale and band, the principle of employing three point on a straight line can be obtained topocentric locus.
the beneficial effects of the utility model are, this scalable biprism has solved prism bar that single prism forms and has caused prism bar to tilt due to surface subsidence or other disturbing factor, thereby the technical matters that the spatial position measuring that affects the ground measuring point is inaccurate, meet the demand had than high measurement accuracy in rugged surroundings, brought very large facility to the work of survey crew.
The accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is described in further detail.
fig. 1 is structural principle schematic diagram of the present utility model.
in Fig. 1,1. prism I, 2. scalable connecting link, 3. fixed length connecting link, 4. prism II, 5. prism bar.
Embodiment
in Fig. 1, this scalable biprism comprises prism I 1, scalable connecting link 2, fixed length connecting link 3, prism II 4 and prism bar 5; The bottom of described prism I 1 housing is connected with being with graduated scalable connecting link 2, scalable connecting link 2 is connected with the top of prism II 4 housings by fixed length connecting link 3, the prism bar 5 that it is taper that the bottom of prism II 4 housings is connecting with graduated bottom downwards; Described prism I 1 and prism II 4 are circular prism; Described prism I 1 housing is plastic material, and the housing of prism II 4, scalable connecting link 2, fixed length connecting link 3 and prism bar 5 are plumbous material, not only light but also firm, adapts to the measurement demand of surveying instrument.While using this biprism to be measured, at first mirror being set high is zero, measured is respectively the volume coordinate at prism I 1 and prism II 4 centers, read respectively the length of 4 of prism I 1 and prism II and prism II 4 to the distance of ground measuring point by the scalable connecting link 2 with accurate scale with the prism bar 5 of accurate scale, adopt the principle of three point on a straight line can obtain topocentric locus.
