in the process of explosion-proof cabin work, the outside harmful gas detection device 6 of room body 1 detects the harmful gas concentration in the environment and gives control module 21 with data transmission, and control module 21 sends control signal for driving piece 33 at the harmful gas concentration that is higher than the default, and driving piece 33 extension, and the closing plate 32 is down this moment, thereby seals fan 11 with sealed ring 12 butt under the effect of abdicating inclined plane 321 and guide surface 121. Meanwhile, the control module 21 sends a control signal to the switch unit 43, and the switch unit 43 is turned on to release the clean air stored in the air storage unit 41 at a certain rate, so as to ensure the normal breathing function of the working personnel in the room body 1.
Then, the air pressure inside the room 1 is detected by the air pressure detecting module 55 inside the room 1, and when the air pressure inside the room 1 is higher than the preset value, the control module 21 sends a signal to the driving cylinder 541, and the driving cylinder 541 contracts, so that the rotating fan 52 can rotate freely. Since the air pressure inside the room body 1 is higher than the air pressure outside the room body 1, the air inside the room body 1 can escape from the air pressure equalizing hole 51 without the entry of harmful gas outside the room body 1. After the air pressure is balanced, the control module 21 sends a signal to the driving cylinder 541, and the driving cylinder 541 extends out, so that the rotating fan 52 is driven to reset; under the effect of the driving cylinder 541, the rotating fan 52 abuts against the sealing rubber ring 13 around the air pressure balance hole 51 to deform the deformation cavity 131, so that the air tightness around the air pressure balance hole 51 is improved, and the harmful gas is reduced.
When the air storage unit 41 releases air, the air pressure detection device 411 on the air storage unit 41 detects the air pressure inside the air storage unit 41 and transmits the air pressure to the control module 21, the control module 21 sends a signal to the voice unit 412 when the air pressure is lower than a preset value, and the voice unit 412 plays a pre-stored voice to prompt an operator to replace the air storage unit 41 or supplement air to the air storage unit 41.
After the air storage unit 41 is deflated for a period of time, the air may be exhausted, and at this time, when the oxygen concentration detected by the oxygen concentration detection device 61 inside the room body 1 drops below the preset value, or when the harmful gas concentration detected by the harmful gas detection device 6 inside the room body 1 rises to reach the preset value, the control module 21 sends a signal to the alarm device 62 to alarm, so as to remind the operator to withdraw from the room body 1 in time, and transmit the data obtained by the analysis instrument inside the room body 1 to the mobile terminal of the operator through the wireless transmission device 63, thereby facilitating remote monitoring.
After the operator evacuates the explosion-proof analysis cabin, the control module 21 controls the flame-retardant opening and closing unit 651 on the flame-retardant gas storage device 65 to open, so that the flame-retardant gas stored in the flame-retardant gas storage device 65 is released, and the probability that the harmful gas in the room body 1 explodes due to electric sparks is reduced. Meanwhile, the air quality detection parameters inside the room body 1 are displayed outside the room body 1 through the display device 66, so that the operator can check the air quality detection parameters before entering the room body 1, and danger caused by too low oxygen concentration inside the room body 1 is prevented. Meanwhile, the display device 66 is a touch screen, so that an instruction can be input, and the control module 21 controls the sealing module 3 to open to circulate air in the explosion-proof cabin when the surrounding environment of the cabin 1 is good.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
