Abstract
The utility model discloses a kind of luminous bar code levelling staff measuring observation for down-hole, tunnel and night, comprise levelling staff, indium watt alloy strip bar code and handle, levelling staff fixes a LED near an indium watt alloy strip bar code, LED is along indium watt alloy strip bar code and be arranged in parallel with an indium watt alloy strip bar code, and LED is connected with switch with external power supply.Levelling staff fixes one near an indium watt alloy strip bar code and moves towards parallel "] with an indium watt alloy strip bar code " shape mounting bar, the groove of mounting bar aims at indium watt alloy strip bar code direction, and LED is arranged in the groove of mounting bar.It mainly solve down-hole, tunnel survey illumination and reduce due to sunlight on daytime irradiate institute produce by the impact on observing buoy such as refractive power, vapours, Atmosphere Refraction.Be convenient to digital leveling instrument and read data, structure is simple, easy to use, is easy to carry, and measures precisely, shortens the instrument image data time.
Description
Technical field
The utility model relates to a kind of survey instrument, specifically, is a kind of luminous bar code levelling staff measuring observation for down-hole, tunnel and night.
Background technology
Current, for down-hole, the bar code levelling staff measuring observation at tunnel and night, be made up of levelling staff, the indium watt alloy strip bar code being pasted onto levelling staff surface and the handle that is positioned at levelling staff side.Carry out down-hole, tunnel and the measurement of higher degree at night time, generally adopt electric torch, hand-held illuminating lamp etc. irradiate levelling staff.It is little, reflective uneven that electric torch irradiates facula area, causes that electronic level image data is slow, error rate is high or not image data.And, in down-hole, tunnel and the measurement of higher degree at night time, for surface irregularity larger area, utilize hand-held lamp source sometimes cannot carry out effective lighting to sight gauge section, cause instrument for a long time cannot reading or increase error rate., use for through long-time, the bar code in indium watt alloy strip is worn dim scale, effectively cannot read data especially or increase error probability with hand-held lamp source meanwhile.
Utility model content
Technical problem to be solved in the utility model is, provide a kind of easy to operate, brightness strong and evenly, read that data are quick, observation quality precision is high, not by other light environment affect for down-hole, tunnel and night measuring the luminous bar code levelling staff observed.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of luminous bar code levelling staff measuring observation for down-hole, tunnel and night, comprise levelling staff, indium watt alloy strip bar code and handle, levelling staff fixes a LED near an indium watt alloy strip bar code, LED is along indium watt alloy strip bar code and be arranged in parallel with an indium watt alloy strip bar code, and LED is connected with switch with external power supply.
Levelling staff fixes one near an indium watt alloy strip bar code and moves towards parallel "] with an indium watt alloy strip bar code " shape mounting bar, the groove of mounting bar aims at indium watt alloy strip bar code direction, and LED is arranged in the groove of mounting bar.
Described mounting bar is trough aluminium alloy track.
The beneficial effects of the utility model are: little power consumption, luminosity are strong, volume is little, low in calories, sturdy and durable, and mounting bar supporter hardness is strong, is convenient to fix with scale.And, easy to operate, read that data are quick, observation quality precision is high, do not affect by other light environment.
Accompanying drawing explanation
Fig. 1 is the utility model measures the luminous bar code levelling staff of observation structural representation for down-hole, tunnel and night.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the luminous bar code levelling staff measuring observation for down-hole, tunnel and night of the present utility model, comprise levelling staff 1, indium watt alloy strip bar code 2 and handle 4, levelling staff 1 fixes a LED 3 near an indium watt alloy strip bar code 2, LED 3 is along indium watt alloy strip bar code 2 and be arranged in parallel with an indium watt alloy strip bar code, LED 3 is connected with switch with external power supply, and power supply and switch are common technology, no longer describes.
Preferably, levelling staff 1 fixes one near an indium watt alloy strip bar code 2 and moves towards parallel "] with an indium watt alloy strip bar code 2 " shape mounting bar 5, the groove of mounting bar 5 aims at indium watt alloy strip bar code 2 direction, and LED 3 is arranged in the groove of mounting bar 5.
Described mounting bar 5 is trough aluminium alloy track.
LED luminescent lamp strip standard is: 60PCS5050LED type aluminium lamp bar, voltage 12V, and every bar light bar has 72 lamp pearls, and each lamp pearl luminous intensity is 16 ~ 18MCD.Lamp pearl lighting angle is 120 degree.LED surface forms an angle of 90 degrees with bar code levelling staff surface.Guarantee that light bar fully illuminates the bar code in indium watt alloy strip.
Can open by switch, close LED after switching on power.Power supply can adopt a kind of small-sized 12V storage battery, can use 6 ~ 7 hours continuously.
Portable accumulator is utilized to power to DEL light bar during measurement.Carry with small-sized 12V storage battery, battery power connecting line is connected with the round pin receptacle be fixed on mounting bar track.Be connected with power switch through round pin receptacle, last and light bar forms power supply closed-loop path again.Used by switch control rule LED.
When powering to LED, in order to save electric quantity of power supply, according to the time of instrument sight scale, by the switch be fixed on mounting bar to regulate light bar power-on time.
After light bar is lighted, electronic level can within 100 meters of scopes, and a scanning indium watt alloy strip bar code carries out record rapidly.
Above-described embodiment is only for illustration of technological thought of the present utility model and feature, its object is to enable those skilled in the art understand content of the present utility model and implement according to this, only can not limit the scope of the claims of the present utility model with the present embodiment, namely the equal change that the spirit that all the utility model disclose is done or modification, still drop in the scope of the claims of the present utility model.
