Abstract

The utility model discloses an electronic level gauge, comprising a rack main block with the bottom surface of the rack main block being level. The electronic level gauge is characterized in that an electrical source, a sealed container filled with conductive liquid, three electric poles, two light-emitting diodes and a switch are equipped on the rack main block. One of the electric poles enters into the sealed container to contact with the conductive liquid sufficiently and is wire spliced with one pole of the power supply, wherein one end of the other two electric poles are respectively connected with two light-emitting diodes, and another end of the two electric poles are in the same level and contacted with the upper surface slightly when the rack main block is positioned horizontally. The two light-emitting diodes are respectively wire spliced with the wire switch which is wire spliced with another power supply. The electronic level gauge can accurately detect surface horizon and be convenient to measure and read data in the imperfect condition of contracted measuring space, dark or feint light or the like.

Description

A kind of electrolevel

Technical field

The utility model relates to the pick-up unit that uses on a kind of engineering, a kind of specifically level meter.

Background technology

In building or decorateing the process of constructing, for the quality that guarantees to construct, usually the usage level instrument positions calibration.Traditional mode is to be used as datum line with cotton rope, however this mode not only labor intensive and time, and out of true very.

Afterwards, people were extensive use of bubble and scale.Bubble and scale comprises the pipe-type bottles of a sealing, contains a bubble that swims in the liquid in the bottle.Rest in the scale mark of being scheduled on the vial when bubble, the surface of being measured just is considered to level or vertical.

Though using this level meter compares more convenient with traditional mode, but determine that by the swing position of bubble surface level is still not too accurate, narrow and small for measurement space, light is too dark or bad condition such as too light under, this bubble and scale just uses relatively difficulty.

The utility model content

Technical problem to be solved in the utility model provides a kind ofly can accurately measure surface level, narrow and small at measurement space, light is too dark or bad condition such as too light under measure, read electrolevel easily, to overcome the deficiency that prior art exists.

In order to solve the problems of the technologies described above, a kind of electrolevel of the utility model comprises a rack body, the basal surface of this rack body is a surface level, it is characterized in that: rack body is provided with power supply, and one fills the airtight container of conductive liquid, three electrodes, two light emitting diodes and a switch; Described one of them electrode gos deep into fully contacting with conductive liquid in the airtight container and being connected with a polar conductor of power supply; Described in addition two electrode one ends are connected with two light emitting diodes respectively, and another end points of these two electrodes exists together in the surface level when the rack body horizontal positioned and contacts with the upper surface summary of conductive liquid; Two light emitting diodes lead respectively connect switch, and switch is another utmost point of wire connecting power again.

Described conductive liquid is a mercury.

Described power supply is a button cell.

Described airtight container is a glass tube.

Adopt technique scheme, when level meter was horizontal, mercury was connected three electrodes, two light emitting diodes are all luminous, and expression tested surface level is when level meter during to lopsidedness, mercury can only conducting two electrodes wherein, have only a lumination of light emitting diode.Therefore, the utility model electrolevel can accurately detect surface level, and narrow and small at measurement space, light is too dark or bad condition such as too light under measure, read conveniently.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is elaborated:

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

Fig. 2 is an electrical block diagram of the present utility model.

Embodiment

A kind of electrolevel as depicted in figs. 1 and 2 comprises the rack body that a retort stand 1 forms, and the basal surface 11 of this retort stand 1 is processed into surface level through grinding machine, meets the measurement standard requirement of level meter.Irritate in the airtight container that placement one glass tube 2 forms on retort stand 1, the glass tube 2 an amount of mercury 21 is arranged, one electrode W gos deep into fully contacting with mercury 21 glass tube 2 from a side of glass tube 2, also have two electrode A, B to insert glass tube 2 from the top of glass tube 2, the lower extreme point of this two electrode A, B is adjusted in the mercury that also omits in the same surface level with in the glass tube 2 and contacts when retort stand 1 horizontal positioned.On retort stand 1, also be provided with a power supply E, two light emitting diode D1, D2, a K switch, wherein power supply E is a button cell.The utmost point of electrode W wire connecting power E, two electrode A, B lead respectively connect light emitting diode D1, D2; The equal again lead of two light emitting diode D1, D2 connects K switch, another utmost point of K switch wire connecting power E.So just constituted an electrolevel.

During use, as long as this electrolevel is placed on the measured surface, if measured surface is a level, mercury 21 will be with electrode A, B, W conducting, and light emitting diode D1, D2 are all luminous, thereby the proof measured surface is a level, if measured surface tilts, mercury 21 will make a lumination of light emitting diode among two light emitting diode D1, the D2, thereby it be oblique to which inclination to judge measured surface with an electrode conduction among electrode W and two electrode A, the B.
