When the transmission shaft 4 is driven to rotate by the telescopic power piece, one end of the rigid chain 6 will be driven by the chain wheel 5 to extend from the telescopic through hole to the bottom of the new energy vehicle chassis.

[0044] The second telescopic transmission piece has the same structure as the first telescopic transmission piece, is arranged in the fire extinguishing protection shell 3, and is symmetrically distributed at a predetermined distance from the first telescopic transmission piece, and one end of the rigid chain 6 of the second telescopic transmission piece is hinged to one end of the rigid chain 6 through a hinge 7.

When the new energy vehicle lithium battery thermal runaway occurs, the one end of the rigid chain 6 will drive the water mist nozzle 13 at one end of the fire-fighting spray hose 12 to extend to the predetermined length at the bottom of the vehicle. At this time, due to the outward stretching of the one end of the fire-fighting spray hose 12, the other end of the fire-fighting spray hose 12 is stretched into a straight line by the S shape to meet the length requirement of the one end of the fire-fighting spray hose 12 stretching outwards. When the fire extinguishing is completed, the staff opens the end cover of one end of the fire extinguishing protective shell 3, starts the motor 8 in reverse, and at the same time the staff pulls out the other end of the fire-fighting spray hose 12; after the one end of the rigid chain 6 resets, the staff places the other end of the fire-fighting spray hose 12 in the S shape in the pipe at one end of the fire extinguishing protective shell 3, and then covers the end cover.

[0049] Further, the vehicle bottom fire extinguishing device is provided with three sets, and the three sets of vehicle bottom fire extinguishing devices are respectively arranged on the lines 2 on both sides of the parking space 1 and on the lines 2 on the rear side of the parking space 1, for simultaneously extending into the water mist nozzle 13 from the bottom of both sides and the rear side of the new energy vehicle for cooling and fire extinguishing.
