Abstract
The utility model belongs to the technical field of optics class, in particular to a readout device based on principle of light refraction; the readout device is used in household electrical meters. The utility model is characterized in that two edge faces of a hollow triangular prism are cut out; a piece of refracting lens is embedded at the inner side of the edge face which is not cut out; a mirror face is placed with a slope angle in the inward and the downward directions; the mirror face is fixedly installed in front of the reading numbers of a household electrical meter. As a result, the reading numbers reflect shadow downward through a refractor, and a meterman can carry out meter reading rapidly without climbing to a high place.
Description
The utility model is that the low hovering of a kind of improvement is looked ability, particularly is in the Meter Reading Device on the watt-hour meter.
Usually the family expenses watt-hour meter is installed in overhead about three meters high, can not observe directly the reading of watt-hour meter.The worker that generally checks meter stands on the stool or with the ladder meter reading that climbs up, and is so not only time-consuming, very dangerous again.
The purpose of this utility model is that a kind of novelty, safety, Meter Reading Device easily and fast will be provided.
The purpose of this utility model is achieved in that a hollow triangular prism, cut out wherein two faceted pebbles, in another faceted pebble inboard, embedding lastblock eyeglass, minute surface is the pitch angle inwardly, downwards and places, the reading that makes watt-hour meter produces refraction by eyeglass, and the angle of minute surface and watt-hour meter reading is: between 30～60, and be fixed on the reading front of watt-hour meter.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is according to the refracting telescope apparatus structure stereographic map that the utility model proposes.Fig. 2 is the sectional view of refracting telescope.
This device comprises a hollow triangular prism support 1 of cutting out two faceted pebbles, and there is a refractor 3 inboard of another faceted pebble 2 of support.
The reading of watt-hour meter is by the refraction of eyeglass, and the worker that at this moment checks meter only need stand in the below of watt-hour meter, but the reading (but reading be inverted image) of direct viewing in the refracting telescope just.The also hand-holdable eyeglass of the worker that checks meter, place refracting telescope under, two minute surfaces relatively and parallel, height and people two are contour.At this moment the reading of watt-hour meter just can have been seen the positive shadow reading of watt-hour meter by twice refraction of eyeglass from following eyeglass.As checking meter night, with the eyeglass in the electric torch flat fire hand, just can normal meter reading.
The utility model just can be realized above-mentioned purpose because only need to mix the meter reading refracting telescope on former watt-hour meter.Adopt the meter reading refracting telescope, work efficiency can improve more than ten times, and can save the labor that the support ladder is held up stool.So be that a kind of spending lacked, and innovation and creation that can obviously improve the work efficiency of checking meter.
Claims (2)
1, the low hovering of a kind of improvement is looked ability, particularly be in the Meter Reading Device on the watt-hour meter, this device has a hollow triangular prism support 1, it is characterized in that cutting out wherein two faceted pebbles, inboard at another faceted pebble 2, be embedded with a refractor 3, minute surface is the pitch angle with the reading of watt-hour meter and places inwardly, downwards.
2, according to the described device of claim 1, the pitch angle that it is characterized in that minute surface and reading is 30～60.
