The invention provides a dangerous waste vehicle transfer safety device. The device comprises a ventilation circuit. The ventilation circuit is characterized in that: a first end of a resistor R2, a negative electrode of a diode D1 and a first end of an input loop of a normally open relay K1 are respectively connected with a +12V power supply, a second end of a resistor R2 is respectively connected with a power supply input end IN of a switch chip U2 and a power supply end VDD of the switch chip U2, the positive electrode of the diode D1 is connected with the signal output end OUT of the switch chip U2 and the second end of the input loop of the normally open relay K1, the adjusting end of an adjustable resistor RP1 is connected with a gating end ST of the switch chip U2, and the grounding end of the switch chip U2 is connected with a power ground; and a first end of an output loop of the normally open relay K1 is connected with a first end of the power supply of a ventilator motor M, a second end of the power supply of the ventilator motor M is connected with a +24V power supply, and a second end of the output loop of the normally open relay K1 is connected with a power ground. When a gas sensitive sensor detects waste gas, the ventilator motor rotates, gas exchange is achieved, and accidents are avoided.

    本发明提出了一种危险废物车辆转运安全装置,该装置包括换气电路,换气电路包括:电阻R2的第一端、二极管D1的负极和常开继电器K1输入回路的第一端分别与+12V电源相连,电阻R2的第二端分别与开关芯片U2的电源输入端IN和开关芯片U2的电源端VDD相连,二极管D1的正极分别与开关芯片U2的信号输出端OUT和常开继电器K1输入回路的第二端相连,可调电阻RP1的调节端与开关芯片U2的选通端ST相连,开关芯片U2的接地端与电源地相连;常开继电器K1输出回路的第一端与换气扇电机M的电源第一端相连,换气扇电机M的电源第二端与+24V电源相连,常开继电器K1输出回路的第二端与电源地相连。气敏传感器检测到废气时,换气扇电机转动,实现气体交换,避免事故发生。
