DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Reference Figures 1 to 4, a ground sprinkler fire extinguishing device for an automobile, comprising:

[0019] The water spray assembly includes a plurality of hard pipes 10, hoses 2, spray heads 3, connecting rods 4, and wheels 5. The hard pipes 10 are connected to the hoses 2 via quick connectors. The spray heads 3 and connecting rods 4 are mounted on the hard pipes 10. The wheels 5 are rotatably mounted on both ends of the connecting rods 4.

[0020] The conveying device includes a base 6, a telescopic tube 7, a connecting pipe 8, a water inlet pipe 9, a first water supply pipe 11 and a conducting device. Both ends of the telescopic tube 7 are provided with water holes communicating with the interior and one end thereof is provided on the base 6. The connecting pipe 8 is detachably connected to the joint on the telescopic tube 7 and the joint at one end of one of the hoses 2. The joints at both ends of the water inlet pipe 9 are connected to the joint at one end of the telescopic tube 7 and the joint at one end of one of the hard tubes 10. The joints at both ends of the first water supply pipe 11 are respectively connected to the joint at the other end of the telescopic tube 7 and the fire hydrant joint. The conducting device is used to open or block the water hole at one end of the telescopic tube 7. In the present invention, when a fire occurs in an electric vehicle, the base 6 is placed on one side of the electric vehicle, one end of the first water supply pipe 11 is connected to the fire hydrant joint, and the other end is connected to the joint at one end of the telescopic tube 7. The hard pipe 10 and the hose 2 are quickly connected through the joint to form a complete water spray assembly. When the fire hydrant is turned on, water flows from the water hole at one end of the telescopic tube 7 into the telescopic tube 7. The telescopic tube 7 is stretched and drives the water spray assembly to move from one side of the electric vehicle to the other side in a horizontal state. When the telescopic tube 7 is stretched, the conduction device works, and the water in the telescopic tube 7 flows from the water hole at the other end of the telescopic tube 7 to the water inlet pipe. 9, and then flows into the hard pipe 10 and the hose 2 through the water inlet pipe 9, and the water is sprayed out from the nozzle 3 to extinguish the fire at the bottom of the electric vehicle. At the same time, the base 6 can be moved to change the position of the nozzle 3, and the fire is extinguished at different positions on the bottom of the electric vehicle. This structure is convenient for assembly and transportation, and the nozzle can be quickly arranged at the bottom of the electric vehicle. At the same time, the cooperation of the hard pipe 10 and the hose 2, during actual use, the hose 2 is in a straightened state, and will not be twisted to cause the nozzle to flip over, and the water spraying assembly is fixed, and the nozzle and the pipeline will not be displaced or flipped under the reaction force of the water spray.

Water holes are provided at one end of each of the rear tube 701 and the front tube 703. Water enters through the water hole at one end of the rear tube 701 and flows into the front tube 703. Due to the function of the guide device, water does not flow out, thereby causing one end of the middle tube 702 to slide within the rear tube 701, and one end of the front tube 703 to slide within the middle tube 702. After the middle tube 702 and the front tube 703 are pulled out, the operating water of the guide device flows out through the water hole at one end of the front tube 703.

[0023] In this embodiment, an annular chute is provided on the inner wall of each of the rear tube 701 and the middle tube 702. Both the middle tube 702 and the front tube 703 have an annular slide at one end that mates with the annular chute. The annular slides at the ends of both the middle tube 702 and the front tube 703 slide in conjunction with the annular chute. Specifically, the rear tube 701 has a through hole for the middle tube 702 to pass through, and the diameter of this through hole is smaller than the diameter of the annular chute on the rear tube 701; the middle tube 702 has a through hole for the front tube 703 to pass through, and the diameter of this through hole is smaller than the diameter of the annular chute on the middle tube 702.

When the middle tube 702 is extended and the front tube 703 is almost pulled to the bottom, the first pull cords 15 are extended to apply tension to the blocking member 13. As the front tube 703 continues to extend forward, the blocking member 13 disengages from the water hole at one end of the front tube 703, opening the water hole. Water flows from the water hole into the water inlet pipe 9, then into the rigid tube 10 and the flexible tube 2, and is sprayed through the nozzle 3.

[0025] In the embodiment, the conveying device comprises a moving device, a second water supply pipe 16, two second pull ropes 17 and a magnetic attractor 18, the two ends of the second water supply pipe 16 are connected with the joint of one end of the hose 2 and the joint of the fire hydrant respectively, the magnetic attractor is adsorbed on the end of the car, the second pull rope 17 connects the hard pipe 10 and the magnetic attractor 18, and the moving device is used for moving the water spraying assembly from one side of the car to the other side.
