Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 be among the present invention the door opening state detecting unit structural representation is set.
The specific embodiment
See also Fig. 1, the invention discloses a kind of air draft control device of Biohazard Safety Equipment.As shown in the figure: it comprise Biohazard Safety Equipment mode of operation detecting unit 11, leave state detection unit 12 and door opening state detecting unit 13, described mode of operation detecting unit 11, the detection signal output that leaves state detection unit 12 and door opening state detecting unit 13 are connected to the detection signal input of control module 2, and the control signal end of described control module 2 connects Electric air valve 3, blower fan 4, uviol lamp 5 respectively.The control signal end of described control module 2 connects Electric air valve 3 by an air-valve actuator 31.The control signal end of described control module 2 is connected blower fan 4 by pressure reduction implementation controller 41 with frequency converter 42.
During use, control module 2 is used to detect the duty of described Biohazard Safety Equipment, and assigns control instruction according to detected duty; Control module 2 is mainly analyzed the working condition of Biohazard Safety Equipment according to the mode of operation detecting units 11 of Biohazard Safety Equipment, the detection signal that leaves state detection unit 12 and door opening state detecting unit 13, and controls the operation of Electric air valve 3 and blower fan 4 according to this.
Pressure reduction implementation controller 41 of the present invention is connected with a frequency converter 42, be used to receive the power output of adjusting described frequency converter 42 after the control instruction that described control module 2 assigns, strengthen or reduce the air quantity of air draft, and then the air quantity of guaranteeing air draft meets the systematic parameter that institute requires or sets in advance in the duty that described control module 2 detects.
(and please consult simultaneously Fig. 1) as shown in Figure 2, the door opening state detecting unit 13 described in the present invention is arranged on a kind of Biohazard Safety Equipment cabinet door with auto-reset function.Described Biohazard Safety Equipment cabinet door with auto-reset function comprises mobile cabinet door 131, main counterweight 132, main counterweight stay cord 133, secondary counterweight stay cord 137, pulley 134, secondary counterweight 135; Wherein, main counterweight stay cord 133 leads by top roller 133, and the sagging two ends of main counterweight stay cord 133 connect mobile cabinet door 131 and main counterweight 132 respectively; Also be provided with one directly over the described main counterweight 132 by point of suspension 138 and stay cord 137) the secondary counterweight 135 of suspention; The weight of described mobile cabinet door 131 adds between the secondary counterweight weight between main counterweight weight and main counterweight; Wear a sensing passage 1321 on the described main counterweight 132, also wear a sensing passage 1351 on the described secondary counterweight 135; The original position both sides of described main counterweight 132 are installed infrared transmitter 1391 and infrared remote receiver 1392 respectively, and the home both sides of described secondary counterweight 135 are also installed infrared transmitter 1393 and infrared remote receiver 1394 respectively; The signal output part of described infrared remote receiver 1392,1394 connects control module 2 respectively, and the control end of described control module 2 then connects uviol lamp 5.Described control module 2 can use single-chip microcomputer 8051.
During use,, illustrate that then main counterweight 132 is in initial position when infrared remote receiver 1392 can receive the signal of infrared transmitter 1391 all the time, mobile cabinet door 131 is in the closed position, infrared signal can be passed the sensing passage 1321 of main counterweight 132, and at this moment, control module 2 control uviol lamps 5 are closed.When infrared remote receiver 1392 can not receive the signal of infrared transmitter 1391, illustrate that mobile cabinet door 131 opened, control module 2 control uviol lamps 5 are opened; When infrared remote receiver 1394 can receive the signal of infrared transmitter 1393 all the time, illustrate that then secondary counterweight 135 is in home all the time, at this moment Biohazard Safety Equipment is not in running order yet, therefore closes by control module 2 control uviol lamps 5.
This shows, by said structure can intelligent automatic control uviol lamp opening and closing, not only laborsaving, and efficient.
Certainly, as a kind of intelligence controlling device of uviol lamp, also can break away from mode of operation detecting unit 11, leave state detection unit 12, parts such as Electric air valve 3, blower fan 4 independently use its function, this also is the much progress of Biohazard Safety Equipment on when using.
