Anti-collision protecting device for fuel gas cylinders of passenger bus

The invention relates to an anti-collision protecting device for fuel gas cylinders of a passenger bus. The anti-collision protecting device comprises a passenger bus underframe anti-collision assembly and fuel gas cylinder mounting protecting assemblies, wherein the passenger bus underframe anti-collision assembly comprises a rectangular frame, a middle rectangular pipe and a supporting part; the rectangular frame is formed by a first rectangular pipe, a second rectangular pipe, a third rectangular pipe and a fourth rectangular pipe, which are in end-to-end connection in sequence, in a surrounding manner; the middle rectangular pipe is fixedly arranged between the first rectangular pipe and the third rectangular pipe; the supporting part is fixedly arranged between the second rectangular pipe and the fourth rectangular pipe; each fuel gas cylinder mounting protecting assembly comprises a gas cylinder fixing hoop, a gas cylinder fixing support and a gas cylinder base support; each gas cylinder fixing support is fixedly mounted above the corresponding gas cylinder base support; the two ends of each gas cylinder fixing hoop are detachably connected with the corresponding gas cylinder base support respectively. Through the adoption of the technical scheme, the anti-collision protecting device can effectively perform anti-collision protection on fuel gas cylinders of the passenger bus, so that the potential safety hazards of a fuel gas passenger bus are eliminated.
