The invention belongs to the technical field of fire fighting trucks, and particularly relates to an underwater detection device of an amphibious fire fighting truck, comprising a fire fighting truck body, a sensor mounted below the fire fighting truck body, a blocking mechanism for preventing dirt in air, a water injection mechanism for guiding water flow into the fire fighting truck body, and a flow dividing mechanism for dividing the water flow into the fire fighting truck body. When the fire fighting truck body enters the water surface, the flow dividing mechanism ascends and reduces the caliber of a water inlet of the plugging mechanism, the water flow flows into the fire fighting truck body through the water injection mechanism, and after the water injection mechanism injects water, the flow dividing mechanism descends and opens the water inlet of the plugging mechanism; water flow enters the fire fighting truck body and extrudes the plugging mechanism to operate. A protection mechanism can be provided for the sensor of the amphibious fire fighting truck, and meanwhile automatic opening and closing protection is provided for the sensor by fully utilizing the pressure of external water flow.

    本发明属于消防车技术领域,具体涉及一种水陆两栖消防车的水下探测装置,包括消防车本体,消防车本体的下方安装有传感器,封堵机构,封堵机构用于防止空气中的污物,注水机构,注水机构用于将水流引至消防车本体的内部,分流机构,分流机构用于分步向封堵机构和注水机构中引入水流,其中,当消防车本体进入水面,分流机构上升并减小封堵机构进水口的口径,水流经由注水机构流入消防车本体的内部,注水机构注水完毕之后,分流机构下降并打开封堵机构的进水口,水流进入消防车本体内部并挤压封堵机构运行。本发明能够为水路两栖消防车的传感器提供保护机制,同时还充分利用外部水流的压力为传感器提供一个自动开合的保护。
