[0026] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0027] Now refer to Figure 1-5, combined with a specific embodiment, it is explained as follows: a confined space harmful gas detection and exhaust device described in the present invention includes a casing body 1, and a support bracket 10 is provided at the inner bottom of the casing body 1. The inner cavity of the casing body 1 can be divided into an upper chamber and a lower chamber by the support bracket 10; a fan 11 fixed to one end of the support bracket 10 is provided inside the upper chamber, and a power supply system 14 fixed on its inner bottom surface is provided inside the lower chamber.

[0028] Referring to the power supply unit of existing electrical equipment, the power supply system 14 is a combination of a built-in lithium battery and an inverter. Through this combination, the exhaust device can function, and the power supply system 14 is equipped with an automatic conversion module, which can choose between the AC power supply mode and the built-in power supply mode.

[0029] A real-time gas detector 13 is provided on one side of the fan 11, and the air inlet of the fan 11 is connected to an exhaust duct 12 arranged inside the upper chamber; the exhaust duct 12 is a telescopic duct, and a fixing plate 15 fixed to the top surface of the support bracket 10 is sleeved on the exhaust duct 12.

[0030] One end of the casing body 1 is provided with an opening door 101 that cooperates with the exhaust duct 12, and the other end of the casing body 1 is provided with a dustproof net 2 that cooperates with the air outlet of the fan 11; below the dustproof net 2 is provided with an operation panel 3 fixed on the end face of the casing body 1, and the operation panel 3 is electrically connected to the fan 11 and the power supply system 14.

[0031] Specifically, a touch screen 4 is disposed on the top surface of the casing body 1 , and the touch screen 4 is electrically connected to the operation panel 3 ; sound and light alarms 5 are disposed on both sides of the top of the casing body 1 , and the sound and light alarms 5 are electrically connected to the operation panel 3 .

[0032] Specifically, referring to the operation panel of the existing electrical equipment, the operation panel 3 is provided with a power display screen, a power switch, a fan switch, a gas detector interface, a gas detector switch, a USB interface, a mains interface, a charging interface and a ground terminal.

[0033] The use principle of the present invention:

[0034] When exhausting air, fully charge the exhaust device, place it near the power well, open the door 101 of the exhaust device, extract the exhaust duct 12, and lead the pipe mouth into the power well. After the exhaust duct 12 is arranged, use a wire to ground the ground terminal to prevent the danger of shell leakage during work. After grounding, use the power cord to connect the mains power through the mains interface, turn on the power switch at this time, and only start the fan switch, and then the fan 11 will start the exhaust work.

[0035] The power supply system 14 has a UPS intelligent switching function. When connected to the mains, the power supply system 14 will prioritize the use of the mains to power the fan 11. If the mains is disconnected during operation, the power supply system 14 will respond in milliseconds and switch to the built-in power supply mode. If there is no mains on site, you can turn on the power switch first, and after the inverter works for 3-5 seconds and the components are running stably, start the fan switch to perform extraction work.

[0036] When detecting gas, first connect the data line of the real-time gas detector 13 to the gas detector interface, and then place the detection end of the data line near the power shaft. After the data line is arranged, press the switch of the gas detector. At this time, the real-time gas detector 13 is working, the touch screen 4 is on, the sound and light alarm 5 is self-checking, and the touch screen 4 startup page forces you to read the operating precautions. After clicking the enter system button, the sound and light alarm 5 ends the self-check, and the real-time gas detector 13 is powered on and preheats its sensor. Then turn on the fan 11 for more than 0.5 hours of ventilation, and then send the detection end of the data line into the power shaft for gas detection. If the gas meets the standard, construction can be started, and the exhaust device continues to maintain ventilation. If the detection does not meet the standard, ventilation treatment needs to be continued until the gas is tested again to meet the standard.

[0037] After the work is finished, if you need to view the abnormal work log, you can directly touch the screen 4 to view the recorded data in the alarm record section, or export the data to Excel. The export steps are: first log in as a user, then log in as an administrator, insert the USB flash drive through the USB interface after successful login, click on the alarm record page to download the data, and finally export the data.
