Abstract

The utility model discloses a self-luminous plumb bob, comprising a plumb bob, a lighting circuit and a side-glowing optical fiber, wherein the plumb bob is connected to the lower end of a plumb bob rope, the lighting circuit is mounted in a hollow cavity inside the plumb bob, the side-glowing optical fiber is laid on the outline of the plumb bob; the lighting circuit comprises a power supply, a switch, a bulb, a concave mirror, and a color filter; the color filter is arranged at the inlet end of the side-glowing optical fiber, the concave face of the concave mirror is arranged right opposite to the color filter; the bulb is arranged between the color filter and the concave mirror, is located at the focus position of the concave mirror, and is in series connection with the power supply through the switch, and the plumb bob rope adopts the side-glowing optical fiber. The self-luminous plumb bob is time-saving and labor-saving, is capable of effectively improving working speed and measuring precision, and is especially suitable for measurement of mine engineering, tunnel construction and other underground constructions and field measurement at night.

Description

A kind of autoluminescence plumb bob

Technical field

The utility model belongs to the underground engineering survey fields such as mine surveying, tunnel survey, is specifically related to a kind of autoluminescence plumb bob.

Background technology

In the surveying work processes such as underground engineering survey, measurement at night, operating personnel often use plumb bob as sighting target, externally in the situation of insufficient light, need to carry out artificial light to plumb bob, not only waste time and energy, and when adopting the external light source illumination, because the problem of angle of incidence of light degree, the brightness that produces easily illumination does not wait, and causes when sighting target, often can not correctly sight the real central axis of target, bring phase difference error to measurement thus.

Summary of the invention

Defective or deficiency for above-mentioned prior art existence, the purpose of this utility model is, a kind of autoluminescence plumb bob is provided, this autoluminescence plumb bob is time saving and energy saving, can Effective Raise operating rate and measuring accuracy, the measurement and the open-air night that are specially adapted to mine engineering, Tunnel Engineering and other underground works measure.

In order to reach above-mentioned target, the utility model adopts following technical solution:

A kind of autoluminescence plumb bob comprises plumb bob, lighting circuit, entirely lighting optical fiber, and wherein, plumb bob is connected to the lower end of plumb bob cotton rope, and lighting circuit is installed in the cavity of plumb bob inside, and entirely lighting optical fiber is laid on the outline of plumb bob; Power for illumination routing power, switch, bulb, concave mirror and color filter form, wherein, color filter is arranged on the inlet end of entirely lighting optical fiber, the concave surface of concave mirror is over against the color filter setting, bulb is arranged between color filter and the concave mirror and is positioned at the focus place of concave mirror, and bulb is connected with power supply by switch.

The utility model also comprises following other technologies feature:

Described plumb bob cotton rope adopts entirely lighting optical fiber.

Advantage of the present utility model is as follows:

1, after the autoluminescence plumb bob places, only need open switch, just can for a long time stable self-luminous lighting, under the working environment a little less than the extraneous lights such as underground, night, can carry out easily surveying work, can avoid the unsettled interference of artificial light.

2, can customize light source colour, select the color filter of different colours, come so that lighting hammer ball is easy to together other light sources difference on every side, easy to identify, be convenient to aiming, not only saved manpower and materials, effectively Reduce measurement error improves measuring accuracy.

3, the plumb bob outline has been arranged entirely lighting optical fiber, and uses entirely lighting optical fiber as the plumb bob cotton rope, and the entirely lighting optical fiber luminescence efficiency is high, and thermal value is little, and is low in energy consumption, saves the energy; Product power≤0.25w/ rice, surperficial illumination reaches 40 ~ 60LX.So that under low light condition, so that under dark or low light condition, whole plumb bob cotton rope and plumb bob outline are very clear, are convenient to survey crew and sight by instrument.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

As shown in Figure 1, autoluminescence plumb bob of the present utility model comprises plumb bob 1, lighting circuit, entirely lighting optical fiber 3, wherein, plumb bob 1 is connected to the lower end of plumb bob cotton rope 2, and lighting circuit is installed in the cavity of plumb bob 1 inside, and entirely lighting optical fiber 3 is laid on the outline of plumb bob 1; Power for illumination routing power 5, switch 6, bulb 7, concave mirror 8 and color filter 4 form, wherein, color filter 4 is arranged on the inlet end of entirely lighting optical fiber 3, the concave surface of concave mirror 8 arranges over against color filter 4, bulb 7 is arranged between color filter 4 and the concave mirror 8 and is positioned at the focus place of concave mirror 8, and bulb 7 is connected with power supply 5 by switch 6.

Entirely lighting optical fiber 3 can be transformed into linear light sorurce with the pointolite that lighting circuit produces, be convenient to survey crew and find rapidly from afar target, be used for thick aiming, in the present embodiment, plumb bob cotton rope 4 adopts entirely lighting optical fiber 3, be the integral body that is communicated with the entirely lighting optical fiber 3 on the outline of plumb bob 1, survey crew just can be seen a clearly pedal line at night like this, can accurately aim at.

During actual the use, can select according to light source on every side the color filter of different colours, so that the utility model and other light sources distinguish.

Principle of work of the present utility model: after closing a switch, power connection, bulb is lighted, produce point source of light, because bulb is positioned over the focus place of concave mirror, point source of light is by the rear directional light that produces of reflection, and this directional light passes through color filter, color filter can be formulated color as required, such as redness, produce at last red directional light, the parallel entirely lighting optical fiber of injecting, light entirely lighting optical fiber, entirely lighting optical fiber produces red wire light source effect, thereby so that plumb bob produces the autoluminescence effect, so that measure operation, it should be noted that: the entirely lighting optical fiber that lays on the plumb bob body mainly is convenient to survey crew and is found rapidly to pounce on from afar to catch target, namely is used for thick aiming; Entirely lighting optical fiber as the plumb bob cotton rope is used for the use of survey crew aiming reading, namely is used for accurately aiming.
