Abstract

The utility model relates to a self-light-emitting substation patrolling route indicator which can emit light at night and is used for indicating routes. The indicator comprises a route indicator shell, wherein a plurality of through holes arranged like an arrow are formed on the surface of the shell; a light-emitting diode (LED) is embedded in each through hole; an LED substrate and a photosensitive control circuit are installed in the shell; the photosensitive control circuit comprises a photoresistor, a relay and a triode; the photoresistor and the relay are connected in series between the base and collector of the triode; the relay is connected with a diode in parallel; a normally open contact of the relay is arranged in a solar battery loop; and a normally closed contact of the relay is arranged in a loop between a rechargeable battery pack and the LED substrate. The indicator has the following advantages: a plurality of LEDs are adopted as the light sources of the indicator, so the indicator saves electricity, is safe and has good lighting effects; and by providing the photosensitive control circuit, the indicator emits light automatically at night, is automatically charged in the day, can be used for a long time without frequent maintenance and has very good economy.

Description

Routing indicator is maked an inspection tour by autoluminescence transformer station

[technical field]

The utility model relate to a kind of can be at noctilucence, be used to indicate the transformer station of route to make an inspection tour routing indicator.

[background technology]

It all is to paint drafting on the wall that the route sign is maked an inspection tour by traditional transformer station, just ineffective to night, can't see, promptly uses fluorescent paint, also must just can be luminous under light-illuminating, can not reach the route purpose of indicating.

[utility model content]

The utility model technical matters to be solved is to provide a kind of, autoluminescence routing indicator that can for a long time use luminous automatically, non-maintaining at night.

The technical scheme of the utility model is: routing indicator is maked an inspection tour by autoluminescence transformer station; Comprise the routing indicator housing; This surface of shell has a plurality of sagittate through holes that are arranged in; Be embedded with light emitting diode in each said through hole, light emitting diode base plate and photosensitive control circuit are housed in the said housing.

As the further improvement of such scheme, said photosensitive control circuit comprises photoresistance, relay and triode, is connected in series said photoresistance and relay between this transistor base and the collector, and said relay and a diode are in parallel installed with; The normally opened contact of said relay is arranged in the solar cell loop, and the normally closed contact of said relay is arranged in the loop between rechargeable battery set and the light emitting diode base plate.

The principle of the utility model is: when daytime is bright and clear; Photoresistance produces electric current, amplifies through triode to be transported to relay, relay adhesive; The closed solar cell of connecting of normally opened contact; Normally closed contact breaks off simultaneously, stops to led powered, and this moment, rechargeable battery set was in charged state; During night, the photoresistance current vanishes, triode ends, and normally opened contact breaks off and blocks the solar cell loop, the normally closed contact adhesive, rechargeable battery set begins to led powered, and light emitting diode begins luminous.With the relay diode connected in parallel is to damage the components and parts in the circuit for the inverse electromotive force that prevents relay coil.

The advantage of the utility model is: adopt a plurality of light emitting diodes as indicator light, and not only power saving but also safety, illuminating effect is good; Owing to be provided with photosensitive control circuit, to night luminous automatically, charge daytime automatically, need not often to safeguard just can use for a long time, economy is very good.

[description of drawings]

Combine embodiment that the utility model is done further to describe with reference to the accompanying drawings.

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

Fig. 2 is the electrical schematic diagram of the utility model.

[embodiment]

Referring to Fig. 1; Routing indicator is maked an inspection tour by autoluminescence transformer station, comprises routing indicator housing 1, and housing 1 surface has a plurality of sagittate through holes that are arranged in; Be embedded with light emitting diode 2 in each through hole, light emitting diode base plate and photosensitive control circuit are housed in the housing 1.

Referring to Fig. 2, photosensitive control circuit comprises photoresistance RL, relay J and triode VT, is connected in series photoresistance RL and relay J between transistor base and the collector, and relay J and diode D are in parallel installed with; Relay normally open contact J1 is arranged in the solar cell SC loop, and relay normally closed contact J2 is arranged in the loop between nickel-hydrogen chargeable cell group HR and the LED, and R is a variable resistor.

The principle of the utility model is: when daytime is bright and clear; Photoresistance RL produces electric current, amplifies through triode VT to be transported to relay J, relay J adhesive; The closed solar cell SC that connects of normally opened contact J1; Normally closed contact J2 breaks off simultaneously, stops to the LED power supply, and this moment, nickel-hydrogen chargeable cell HR group was in charged state; During night, photoresistance RL current vanishes, triode VT ends, and normally opened contact J1 breaks off and blocks solar cell SC loop, normally closed contact J2 adhesive, nickel-hydrogen chargeable cell group HR begins to the LED power supply, and LED begins luminous.With relay J diode connected in parallel D is to damage the components and parts in the circuit for the inverse electromotive force that prevents relay coil.

Although illustrated and described the embodiment of the utility model; For those of ordinary skill in the art; Be appreciated that under the situation of principle that does not break away from the utility model and spirit and can carry out multiple variation, modification, replacement and modification to these embodiment, the scope of the utility model is limited accompanying claims and equivalent thereof.
