Abstract
The invention relates to an electrolevel which comprises an aluminium alloy housing. A liquid detection switch, a control an indication circuit, a power supply, a power switch and a liquid level indicator are disposed inside the housing and are electrically connected with each other. The power switch and the liquid level indicator extend from the inside of the housing to the outside of the housing. According to the invention, the inclination direction of an object surface can be conveniently and rapidly detected only by observing light emitting diodes on two ends of the electrolevel. In addition, the detection and observation can be carried out even in a dark or dimmed environment.
Description
Technical field
The present invention relates to a kind of electrolevel, mainly solved the defective that common level meter perhaps is not easy to see clearly at night in dimly lit environment.
Background technology
At present, the common level meter of Xiao Shouing mainly is to lean on bubble move left and right in the liquid to judge whether level of plane on the market, and so common level meter is not easy to see clearly at night or in the environment of dim light.
The present great majority of electrolevel are made according to optical imaging concept and sensor technology, its complex structure, and cost is higher, and price is more expensive, and easy care is not indicated not eye-catching under the dim light situation.
Summary of the invention
The technical matters that the present invention will solve is: even propose a kind of electrolevel that under the situation of insufficient light, also can see horizontality clearly.
The technical scheme that the present invention adopted is: a kind of electrolevel, comprise aluminum alloy casing, and be provided with liquid detector switch, control and indicating circuit, power supply, power switch and fluid level gauge in the described shell, be electrical connection between the each several part; Described power switch and fluid level gauge extend out to housing exterior by enclosure.
Specifically; Liquid detector switch of the present invention has a plastic casing; Be loaded with conducting liquid in the described plastic casing; The two ends ecto-entad of plastic casing is inserted with two electrodes respectively to conducting liquid; All have electrode unsettled and equidistantly be arranged on the conducting liquid surface in set two electrodes of every end, another root electrode of every end inserts in conducting liquid; Described four electrodes all are connected with control and indicating circuit.
Say that further in order to save cost and to strengthen conductive effect, conducting liquid of the present invention is a mineral water, described electrode is a tinsel.
In addition, control of the present invention and indicating circuit are transistor circuit, and its enlargement factor is 200～250 times; Described power source voltage is 4.5～5V; Described fluid level gauge is a light emitting diode.。
Principle of work of the present invention is: utilize high sensitivity fluid level switch and illuminating circuit to drive two light emitting diodes, when the complete level of object surfaces, two light emitting diodes all do not work; A body surface left side if high right low (being tilted to the right), the diode on the right is bright, and the inclination angle is big more, brighter display; Otherwise a right high left side low (being tilted to the left), then left side diode is bright, and brightness also increases along with the increase at inclination angle.
The invention has the beneficial effects as follows: only need the light emitting diode at eye-level appearance two ends just can conveniently detect the vergence direction of body surface, even and in the environment of dark or dim light, also can detect and observe.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Fig. 2 is circuit theory diagrams of the present invention;
Fig. 3 is a theory diagram of the present invention;
Among the figure: 1, shell; 2, power switch; 3, fluid level gauge.
Embodiment
Combine accompanying drawing and preferred embodiment that the present invention is done further detailed explanation now.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, a kind of electrolevel comprises aluminum alloy casing 1, is provided with liquid detector switch, control and indicating circuit, power supply, power switch 2 and fluid level gauge 3 in the described shell 1, is electrical connection between the each several part; Described power switch 2 and fluid level gauge 3 extend out to housing exterior by enclosure.
Described aluminum alloy casing is to be used for fixing liquid detector switch, control and indicating circuit, power switch etc., so that form the shell of a sealing.
The liquid detector switch has a plastic casing that is made by transparent hard moulding material; Be loaded with conducting liquid in the described plastic casing; The two ends ecto-entad of plastic casing is inserted with two electrodes respectively to conducting liquid; All have electrode unsettled and equidistantly be arranged on the conducting liquid surface in set two electrodes of every end, another root electrode of every end inserts in conducting liquid; Described four electrodes all are connected with control and indicating circuit.Four electrodes use are difficult for by the tinsel of water erosion (like the lead of nickel plating, chromium plating), seal with the marine glue cementation with microbit punching back.In order to improve sensitivity, liquid detector switch length as far as possible more greatly, above two electrodes will be as far as possible near the water surface, obvious for making effect, liquid adopts mineral water.
Control and display circuit adopt enlargement factor to be about 200 transistor circuit; Supply voltage is 4.5V, is composed in series by three No. 5 batteries of joint (also can be No. 7 batteries); Power switch adopts small-sized locking press button switch, mainly is used for controlling the power supply that provides to indicating circuit; Fluid level gauge is high-brightness LED pilot lamp (high brightness LED).
The principle of work of the present invention and the course of work are like Fig. 2, shown in 3: when the plane complete level surveyed, the resistance between electrode C and electrode A, the B is infinity, and two triodes all are in cut-off state, about two diodes not luminous.When the plane is tilted to the left, owing to electrode A contacts with water, the resistance between A, C, the triode conducting on the left side, the lumination of light emitting diode on the left side, the pitch angle is big more, and the resistance between A, the C is more little, and light emitting diode is bright more; When the plane is tilted to the right, because electrode B contacts with water, the resistance between B, the C, the triode conducting on the right, the light emitting diode on the right is shinny, and the pitch angle is big more, and B, C resistance are more little, and light emitting diode is bright more.
Just the specific embodiment of the present invention of describing in the above instructions; Various not illustrating constitutes restriction to flesh and blood of the present invention; Under the those of ordinary skill of technical field after having read instructions can to before described embodiment make an amendment or be out of shape, and do not deviate from essence of an invention and scope.
