The height of the bearing column 32 is less than that of the sliding chute 31, that is, the inner buffer spring 34 is prevented from being completely extruded, so as to protect the inner buffer spring 34 and prolong the service life of the inner buffer spring 34.

In the process of using the fire-fighting emergency rescue device, the whole device is pushed to a fire-fighting place through the supporting rod 7 in cooperation with the steering wheel 15 and the directional wheel 19, the reaction force between fire-fighting personnel and the supporting rod 7 is relieved through the arrangement of the rubber sheath 9, a water belt 53 is connected with the input end of a second gate valve 52, the second gate valve 52 is opened, water flows into a mixing pipe 54 through the second gate valve 52, a small part of water flows into a foam liquid storage tank 4 through a water pipe 55, proportional mixing is carried out between the water belt and the foam liquid in the foam liquid storage tank 4 through a proportional mixer, the diluted foam liquid reenters the mixing pipe 54 through the foam pipe 58 through water pressure and is mixed with the majority of water flows to form foam, finally, the first gate valve 51 is opened, the foam is sprayed out of a spray gun 60 through the first gate valve 51, and the whole fire-fighting operation is completed, the flow rate of the foam liquid entering the foam liquid storage tank 4 is controlled through the first ball valve 57, the amount of the foam liquid mixed with the flow is further controlled, the amount of the diluted foam liquid flowing into the mixing pipe 54 is controlled through the second ball valve 59, the dilution degree of the foam is further controlled, the bumping received by the foam liquid storage tank 4 during movement is reduced through the buffer component 12, if the foam liquid storage tank 4 vibrates downwards, the foam liquid storage tank 4 downwards extrudes the mounting plate 1, the mounting plate 1 drives the connecting plate 11 to move downwards, the connecting plate 11 downwards extrudes the upper mounting block 21, the upper mounting block 21 drives the outer sleeve 22 to move downwards, meanwhile, the upper mounting block 21 downwards extrudes the outer buffer spring 23, the outer buffer spring 23 absorbs the downward acting force received by a part of the upper mounting block 21, the outer sleeve 22 downwards extrudes the inner buffer spring 34, the inner buffer spring 34 is contracted by force and then absorbs a part of the downward acting force received by the upper mounting block 21, if the foam liquid storage tank 4 generates upward vibration, in the same way, the outer buffer spring 23 and the inner buffer spring 34 are stressed to extend, a part of upward acting force applied to the upper mounting block 21 is counteracted together, the vibration applied to the foam liquid storage tank 4 is effectively reduced through double shock absorption of the outer buffer spring 23 and the inner buffer spring 34, sundries in forest land are prevented from being drawn into the steering wheel 15 through the mud guard 16, the steering wheel 15 is prevented from being blocked and stopped, the hardware requirement of moving in the forest land is met through the steering wheel 15 and the directional wheel 19 with larger rim diameters, the normal use of the invention in the forest land is ensured to the maximum extent, the elevation angle of the spray gun 60 is changed through the angle adjusting mechanism 17, and if the elevation angle of the spray gun 60 needs to be increased during use, the output ends of the two electric telescopic rods 42 synchronously drive the mounting plate 1 to move downwards through starting the two electric telescopic rods 42, mounting panel 1 uses two connecting plates 11 to rotate under the axial, mounting panel 1 drives two T shape slide bars 45 and slides down in two arc spout 44 respectively simultaneously, mounting panel 1 drives spray gun 60 and uses two connecting plates 11 to rotate under the axial, spray gun 60's injection angle of elevation has been increased promptly, if the angle of elevation that needs reduce spray gun 60, only need two electric telescopic handle 42 output synchronous ascent can, through setting up the angle of elevation regulation limit that arc spout 44 restricted mounting panel 1, it is excessive to avoid mounting panel 1 angle of elevation to adjust, lead to electric telescopic handle 42 to damage.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
