It closes, touch screen 8 is installed on the 5 side outer wall of ring stand, the side wall of the shading column 1 is equipped with limit switch SQ, the screening
It is additionally provided with delay in light beam 1 and disconnects one KT1 of relay, one KT2 of time delay closing relay, delay disconnection two KT3 of relay, delay
Two KT4 of closing relay, circuit breaker Q is additionally provided on the side wall of the shading column 1, and the circuit breaker Q, the delay disconnect relay
One KT1 of device, one KT2 of the time delay closing relay, the delay disconnect two KT3 of relay, the time delay closing relay two
KT4, the limit switch SQ, the motor 7 are connected by conducting wire.
The barn door 2 is tapered, and the vertical projection of the touch screen 8 is located at the range of 2 vertical projection of barn door
It is interior.
The delay disconnects one KT1 of relay, one KT2 of the time delay closing relay, delay disconnection relay two
KT3, two KT4 of the time delay closing relay are arranged successively from top to bottom.
Working principle: the circuit breaker Q of the utility model and delay disconnect the normally-closed contact of one KT1 of relay, delay disconnection
Power supply is accessed after the coil series connection of one KT1 of relay, forms control circuit one；Delay disconnects the normally opened contact of one KT1 of relay
Power supply is accessed after connecting with the coil of one KT2 of time delay closing relay, forms control circuit two；One KT2 of time delay closing relay
