Abstract

The utility model relates to an inclination automatic-prompting level which is composed of a level body, an overhanging system and a sounding circuit, wherein, a metal scroll is arranged on the overhanging system. One side of the metal scroll is provided with a precision setting knob, and the upper half part of a metal soft wire is wound on the metal scroll. The lower end of the metal soft wire is hung with a metal cone hammer, and a metal contact ring is arranged at a position of surrounding the metal cone hammer. A speech module is arranged in the sounding circuit, and a loudspeaker and a rotary switch are connected with the sounding circuit. The disadvantage that the level of the prior art can not be ensured to be parallel to a verticality line is altered by the inclination automatic-prompting level of the utility model. Especially because a speech prompting and an accuracy grade setting functions are provided, the inclination of the level has quantization index. Thus the fine measurement and the simple measurement can be conveniently realized, and the efficiency of the measuring work is raised.

Description

Prompting levelling pole automatically tilts

Technical field: the utility model relates to surveying instrument, relates in particular to a kind of being equipped with by the inclination of measuring grade setting, vergence direction language system for prompting and points out levelling pole automatically.

Background technology: the levelling pole of prior art, be difficult for the problem vertical in order to solve artificial support levelling pole with geoid surface, the comparatively advanced way that adopts is that the side at levelling pole is equipped with a circular bubble, bubble thinks promptly that between two parties ruler is vertical with geoid surface, but there is following defective: one, the radius of general its spherical arc of circular bubble has only 0.5 to 2.0 meter, general chi with the scale unit of circular bubble all 10 ' about, its precision is very low; They are two years old, when extreme terrain is measured, the measurement of, water gauge stake domatic etc. as hillside, buildings, riverbed, the person is difficult to freely stand to hold up the chi, can't watch circular bubble, can only roughly set upright with sensation, adopt " setting " method reading at a puss, but " setting " also can only be about or rock back and forth, eliminate droop error and be difficult in 360 ° of scopes, and the reading error that at this moment often causes is quite big.In the inclined angle alpha=1 ° 00 ' time of levelling pole, middle silk reading height h=2.7m, reading error δ=0.4mm; In the inclined angle alpha=1 ° 30 ' time of levelling pole, middle silk reading height h=2.7m, reading error δ=0.9mm; In the inclined angle alpha=2 ° 00 ' time of levelling pole, middle silk reading height h=2.7m, reading error δ=1.6mm; In the inclined angle alpha=2 ° 30 ' time of levelling pole, middle silk reading height h=2.7m, reading error δ=2.6mm; In the inclined angle alpha=3 ° 00 ' time of levelling pole, middle silk reading height h=2.7m, reading error δ=3.7mm; In the inclined angle alpha=4 ° 00 ' time of levelling pole, middle silk reading height h=2.7m, reading error δ=8.6mm.This shows that reading error can not be ignored.

The purpose of this utility model is, overcome the deficiencies in the prior art part, provide a kind of being equipped with to point out levelling pole automatically by the inclination of measuring grade setting, vergence direction verbal cue system, with simple as far as possible equipment setting, realize measuring as far as possible accurately, accelerate the measurement progress, reduce the waste of manpower and materials.

Summary of the invention: levelling pole is pointed out in inclination described in the utility model automatically, relates to the levelling pole body, and the levelling pole body is provided with the graduation apparatus of expression measurement unit, is provided with the system of dangling and the phonation circuit that is connected with the system of dangling in the levelling pole body.The said system of dangling includes the gentle silk of metal spool, precision set knob, metal, metal awl hammer, metal and touches ring and form, the top of the said system of dangling is provided with the metal spool, side at the metal spool is provided with the precision set knob, on the metal spool, be wound with the upper half part of the gentle silk of metal, be hung with metal awl hammer in the lower end of the gentle silk of metal, be provided with metal around the position of metal awl hammer and touch ring, in described phonation circuit, be provided with voice module.In circuit of the present utility model, being connected with described phonation circuit is provided with loudspeaker; Be connected with described phonation circuit and be provided with rotary switch, rotary switch battery main switch just of the present utility model; Being connected with described phonation circuit is provided with battery, battery general supply just of the present utility model, and rotary switch is connected with battery by circuit.

The system of the dangling support arm that the utility model uses, it is the hollow square pipe made from organic transparent material, in order to the spool of the gentle silk of metal to be installed at an upper portion thereof, the bottom is installed metal and is touched ring, for can make metal awl hammer placed in the middle the time, the middle line parallel of its vertical line direction and levelling pole body, outside at four faces of hollow square pipe lower end, two springs and two screws are installed respectively, screw is relative with spring, be convenient to adjusting screw and make the square tube fine motion, when the levelling pole body is in vertical direction, transfer to metal awl hammer placed in the middle.

Levelling pole is pointed out in inclination described in the utility model automatically, and the system of dangling is installed in the bottom of levelling pole body, and apart from 0.1 meter of " zero " point, to reduce the amplitude of oscillation of metal awl hammer, the direction that the metal of guaranteeing the four arcs shape touches ring and four faces of levelling pole body aligns respectively.Rotary switch and loudspeaker are installed in 1.2 and 1.3 meters respectively, be convenient to operation and voice and answer, battery and phonation circuit are arranged at the position near rotary switch, and this mainly is for the ease of wiring, there is not any special needs, as long as there is the appropriate location firmly to lay.Here said rotary switch also can be the pushbutton switch as power switch.

Use inclination described in the utility model to point out levelling pole automatically, the levelling pole that has changed prior art can't guarantee the drawback parallel with plumb line; Especially because verbal cue arranged, stand extreme terrain, the person that holds up the chi that " blind holding up " also can guarantee reading accuracy when limited, avoided doing over again in a large number; The accuracy class set-up function has been arranged, made the degree of tilt of levelling pole that quantizating index arranged, can realize " accurate measurement " and " letter is surveyed " easily, surveying work efficient improves greatly.
