Summary of the invention
(1) technical problem that will solve
For solving the problem, the present invention proposes a kind of ammeter box; Circuit breaker and ammeter are locked in box inside, can play a protective role, electric-controlled mechanical can be realized by automatically controlled mode simultaneously and close a floodgate.
(2) technical scheme
A kind of ammeter box of the present invention, comprises casing, and is installed on ammeter and the circuit breaker of box inside; Described circuit breaker and ammeter Electricity Federation, also comprise U-shaped optoelectronic switch, air spring, button, LED light and control circuit; Described U-shaped optoelectronic switch is installed on the plectrum both sides of circuit breaker; Described air spring is installed on bottom U-shaped optoelectronic switch; Described control circuit electrical connection button, air spring, LED light and U-shaped optoelectronic switch.
Further, described U-shaped optoelectronic switch is made up of U-shaped box body and photoelectric tube; The groove depth of described U-shaped box body is 3cm; Described photoelectric tube is installed on both sides, U-shaped box body top; Described air spring is embedded into the groove inside bottom of U-shaped box body.
Further, described U-shaped box body offers two tapped through holes.
Further, described control circuit is made up of the drive circuit of low and high level decision circuitry and air spring 555 chips.
Further, described button is installed on tank surface.

(3) beneficial effect
Compared with prior art, a kind of ammeter box of the present invention, is locked in box inside by circuit breaker and ammeter, can protective circuit breaker and ammeter is not damaged and steal; Serve protective effect well, simultaneously U-shaped optoelectronic switch controls the light on and off of LED, can knowledge relay operating state; Electric-controlled mechanical can be realized additionally by button to close a floodgate.
Accompanying drawing explanation
Fig. 1 is open mode structure structural representation of the present invention;
Fig. 2 is closure state structure structural representation of the present invention.
A kind of ammeter box as depicted in figs. 1 and 2, comprises casing 1, and the ammeter 2 be installed on inside casing 1 and circuit breaker 3; Described circuit breaker 3 and ammeter 2 parallel connection; Also comprise U-shaped optoelectronic switch 4, air spring 5, button 6, LED light 13 and control circuit 7; Described U-shaped optoelectronic switch 4 is installed on plectrum 12 both sides of circuit breaker 3; Described air spring 5 is installed on bottom U-shaped optoelectronic switch 4; Described control circuit 7 is electrically connected button 6, air spring 5, LED light 13 and U-shaped optoelectronic switch 4; Described button 6 is installed on casing 1 surface; Described casing 1 is provided with lockhole 11.
Described U-shaped optoelectronic switch 4 is made up of U-shaped box body 8 and photoelectric tube 9; The groove depth of described U-shaped box body 8 is 3cm; Described photoelectric tube 9 is installed on both sides, U-shaped box body 8 top; Described air spring 5 is embedded into the groove inside bottom of U-shaped box body 8; Because U-shaped optoelectronic switch two ends essence is transmitting and receiving circuit, once tripping operation, the signal that transmitting terminal is launched, receiving terminal does not receive, and it can produce a drop-down low level, after control circuit 7 detects low level, to LED light 13 signal, LED light 13 is lit, until after closing a floodgate, level is driven high, and LED light knocks out.
Described U-shaped box body 8 offers two tapped through holes 10.
Described control circuit 7 is made up of the drive circuit of low and high level decision circuitry and air spring 555 chips; Because the drive circuit of low and high level decision circuitry and air spring is all typical circuits of the prior art, directly can quotes, not repeat them here; Low and high level decision circuitry detects low level signal, and 555 chip outputs export a low level signal, are dragged down by LED light 13 level; Lighted; Button is pressed, and the drive circuit of air spring 5 is communicated with; Realize air spring 5 pushes up, after plectrum 12 is pushed up certain altitude, plectrum 12 is subject to the shell fragment effect inside circuit breaker 3, realizes closing a floodgate; When air spring 5 works, form an impulsive force, eject the contraction of rear horse back and get back to bottom U-shaped box body 8.
A kind of ammeter box of the present invention, is locked in box inside by circuit breaker and ammeter, can protective circuit breaker and ammeter is not damaged and steal; Serve protective effect well, simultaneously U-shaped optoelectronic switch controls the light on and off of LED, can knowledge relay operating state; Electric-controlled mechanical can be realized additionally by button to close a floodgate.
