Abstract

The utility model discloses a total station prism suitable for underground engineering measurement, which comprises a switch, a prism base, three groups of LED red lamps, a group of LED white lamps, a power supply and a charging jack; the switch and the power supply are fixed on the target plate through screws, the four groups of LED lamps are connected in parallel, the three groups of LED red lamps are placed at the target positions of the triangular vertexes on the target plate to emit clear red light, the group of LED white lamps are regularly and densely arranged on the whole target plate to emit clear white light, and the three groups of bright red triangular lines, namely the target, can be found in the dark. Under the condition that light is insufficient or the distance between the prism and the total station is small, observation personnel can conveniently find the target vertex to perform accurate measurement. The utility model discloses can carry out measurement under the not enough condition of light, labour saving and time saving has not only improved measurement work efficiency, has still improved measurement accuracy simultaneously.

Description

Total powerstation prism suitable for underground engineering survey

Technical Field

The utility model relates to a measuring instrument field especially relates to total powerstation prism suitable for underground works is measured.

Background

The total station is an instrument frequently used in measurement work, can automatically measure edges, angles, distance and the like, greatly improves the working efficiency, but when the total station is used for underground engineering measurement to work, a special worker is required to illuminate the prism to find the prism position of the total station, even if the prism is found, if the incident angle of light is not right, an observer is difficult to find the central position of the prism, and needs to continuously communicate with an illuminator and continuously adjust to find a proper light incident angle. When the distance between the prism and the total station is small, the center of the prism still cannot be accurately found under the condition of illumination, and in high-precision measurement, if the center of the prism cannot be aimed, a great error is caused by angle measurement and edge measurement, so that the measurement precision is influenced, and the standard of engineering measurement is not met.

Disclosure of Invention

The utility model aims at providing a total powerstation prism suitable for underground engineering survey can effectively solve under not enough and prism and the less condition of total powerstation distance of light, is difficult to carry out the problem of accurate measurement. The utility model discloses labour saving and time saving has greatly improved work efficiency and quality.

In order to achieve the purpose, the utility model provides a total powerstation prism suitable for underground engineering survey, characterized by include switch, prism base, three LED red lights of group, a set of LED white light, power, the jack that charges, the switch is fixed on the board by the screw with the power, four LED lights of group are parallelly connected and establish ties with power and switch, three LED red lights of group are placed in the triangle summit target position on the board, and a set of LED white light is neatly arranged in an orderly and intensive way on whole board, the prism leans on the helicitic texture to twist on the prism base.

The power source is a rechargeable lithium battery.

The utility model discloses a settle the LED lamp on the board of observing, make operating personnel in the dark surrounds to and under prism and the less condition of total station distance, the position of total station prism is confirmed fast, and illuminates through four LED lamps of group, can obviously discover to have red bright line, can be clear find target the fixed position on the board of observing the summit, realize more accurate measurement. The utility model discloses labour saving and time saving, simple structure, it is convenient to realize, has not only improved work efficiency, has improved measurement accuracy moreover.
