[0023] See also Figure 1-Figure 3 , Figure 1 It is a structural schematic diagram of the fire sprinkler gun in the embodiment, Figure 2 This is one of the schematic diagrams of the explosion structure of the nozzle mechanism in the embodiment. Figure 3The second schematic diagram of the explosion structure of the nozzle mechanism in the embodiment. A fire sprinkler in this embodiment includes a nozzle mechanism 1 and a holding mechanism 2, wherein the nozzle mechanism 1 includes a first conducting pipe 11, a second conducting pipe 12 and a plurality of spraying pipes 13, the first conducting pipe 11 and the second conducting pipe 12 are arranged at intervals and parallel to each other, and the plurality of spraying pipes 13 are arranged between the first conducting pipe 11 and the second conducting pipe 12, and are arranged in sequence along the length direction of the first conducting pipe 11, and the two ends of each spraying pipe 13 are respectively connected to the first conducting pipe 11. and the second conducting pipe 12, the spraying pipe 13 is provided with a plurality of rows of first spraying holes 131, each row of the first spraying holes 131 is arranged along the length direction of the spraying pipe 13, and the plurality of rows of the first spraying holes 131 are arranged along the circumference of the spraying pipe 13. The first conducting pipe 11 also has a water inlet interface 111 on the side facing away from the spraying pipe 13, and the water inlet interface 111 can be used to connect a fire hose. One end of the holding mechanism 2 is fixed to the first conducting pipe 11, and the other end extends in the direction facing away from the second conducting pipe 12.

[0024] When a fire occurs in the electric vehicle, a fire hose can be connected to the water inlet interface 111 to supply water to the sprinkler mechanism 1, and then the sprinkler mechanism 1 is placed under the electric vehicle. The water flows into the multiple spray pipes 13 respectively through the first conducting pipe 11. Since the multiple groups of spray mechanisms 131 are arranged along the circumference of the spray pipes 13, when the spray pipes 13 are placed horizontally at the bottom of the car, the multiple groups of first spray holes 131 spray toward the bottom of the electric vehicle from different angles, so that the water flows to cover the bottom of the car, thereby cooling the battery pack at the bottom of the electric vehicle, that is, improving the uniformity of water spraying the bottom of the car and improving the fire extinguishing efficiency. During the process, the user can hold the holding mechanism 2 to adjust the sprinkler mechanism 1 at a position away from the electric vehicle to ensure the safety of personnel.

[0025] Furthermore, the first conducting tube 11 is provided with a plurality of first conducting holes 112, and the plurality of first conducting holes 112 are arranged along the length direction thereof. The second conducting tube 12 is provided with a plurality of second conducting holes 121 corresponding to the first conducting holes 112, and the plurality of first conducting holes 112 are respectively opposite to the plurality of second conducting holes 121. Both ends of the spraying tube 13 are respectively connected to the first conducting holes 112 and the second conducting holes 121.

[0026] The first conducting hole 112, the second conducting hole 121 and the water inlet interface 111 are all provided with a first connector 01, and the two ends of each spray pipe 13 are respectively provided with a second connector 02, and the second connector 02 of the spray pipe 13 is respectively connected to the first connector 01 of the first conducting hole 112 and the second conducting hole 121, so that the two ends of the spray pipe 13 are respectively connected to the first conducting pipe 11 and the second conducting pipe 12, and the first connector 01 of the water inlet interface 111 is used to connect the fire hose. In this example, the first connector 01 is the female head of the fire card type quick connector, and the second connector 02 is the male head of the fire card type quick connector. In specific implementation, the first connector 01 is welded to the first conducting hole 112, the second conducting hole 121 and the water inlet interface 111 by welding, and the second connector 02 is also fixed to the two ends of the spray pipe 13 by welding.

[0027] In this way, when the nozzle mechanism 1 is not in use, the second connectors 02 at both ends of the spray pipe 13 can be removed from the first connectors 01 on the first conducting pipe 11 and the second conducting pipe 12 respectively, so as to reduce the space occupied by the nozzle mechanism 1 when it is idle and facilitate storage and carrying. Conversely, when it is needed, the second connectors 02 at both ends of the spray pipe 13 can be plugged into the first connectors 01 on the first conducting pipe 11 and the second conducting pipe 12 to quickly complete the assembly and put it into use.

[0028] Preferably, the first conducting tube 11 further has a plurality of groups of second spray holes 113, which are arranged through the top and bottom surfaces of the first conducting tube 11, and are arranged along the width direction of the first conducting tube 11, and each group of second spray holes 113 is arranged along the length direction of the first conducting tube 11. Similarly, the second conducting tube 12 has a plurality of groups of third spray holes 122, which are arranged through the top and bottom surfaces of the second conducting tube 12, and are arranged along the width direction of the first conducting tube 11, and each group of third spray holes 122 is arranged along the length direction of the first conducting tube 11. When in use, the second spray hole 113 and the third spray hole 122 also spray water toward the bottom of the car to increase the water spray coverage area and further improve the efficiency of cooling and fire extinguishing. It can be understood that since the second spray hole 113 and the third spray hole 122 respectively penetrate the bottom surface and the top surface of the first through tube 11 and the second conducting tube 12, there is no need to distinguish the positive and negative directions of the sprinkler mechanism 1 when in use, and the sprinkler mechanism 1 can be quickly put into use to further improve the fire extinguishing efficiency.

[0029] See also Figure 4 , review Figure 1 , Figure 4Schematic diagram of the structure of the holding mechanism in the embodiment. Further, two connecting platforms 114 are provided on the side of the first conducting pipe 11 facing away from the spraying pipe 13. The two connecting platforms 114 are provided on both sides of the water inlet interface 111. Each connecting platform 114 is provided with a connecting hole 1141. The connecting hole 1141 penetrates the top and bottom surfaces of the connecting platform 114 along the thickness direction of the connecting platform 114. The holding mechanism 2 is connected to the connecting hole 1141.

[0030] Specifically, the holding mechanism 2 includes a holding body 21 and a connecting body 22. The connecting body 22 includes a first connecting tube 221 and a connecting head 222 provided at one end of the first connecting tube 221. The connecting head 222 is provided with two connecting posts 2221 corresponding to the connecting hole 1141. The connecting posts 2221 are plugged into the connecting hole 1141. One end of the holding body 21 is connected to the other end of the first connecting tube 221. Similarly, when the fire sprinkler is idle, the holding mechanism 2 can be removed from the nozzle mechanism 1, so that it is more convenient to store and carry. Conversely, when it is needed, the connecting posts 2221 of the connecting head 222 are plugged into the connecting hole 1141 to complete the assembly of the holding mechanism 2 and the nozzle mechanism 1.

[0031] Preferably, a first through hole 223 is provided on the side wall of the first connecting tube 221 near one end of the gripping body 21, and the first through hole 223 penetrates the first connecting tube 221 along the thickness direction of the first connecting tube. The gripping body 21 includes a second connecting tube 211 and a gripping head 212. One end of the second connecting tube 211 has a connecting section 2111, which has a plurality of second through holes 21111, which are arranged along the length direction of the connecting section 2111 and also penetrate the connecting section 2111 along the thickness direction of the connecting section 2111. The connecting section 2111 is plugged into one end of the first connecting tube 221 and slides along the inner wall of the first connecting tube 221. The plurality of second through holes 21111 are sequentially opposite to the first through holes 223, and the gripping head 212 is provided at the other end of the second connecting tube 211. In specific implementation, bolts can be used to sequentially penetrate the first through hole 223 and the second through hole 21111 to fix the gripping body 21 and the connecting body 22.

[0032] It is understandable that, in specific implementation, the second connecting tube 211 can be pulled according to actual usage requirements, so that the connecting section 2111 slides in the first connecting tube 221 to adjust the length of the holding mechanism 2. After the adjustment is completed, the first through hole 223 and the corresponding second through hole 21111 can be fixed with bolts.

[0033] In summary, in this example, by placing the nozzle mechanism at the bottom of the electric vehicle, water is sprayed directly toward the bottom of the vehicle through multiple groups of first spray holes of multiple spray pipes, so that the water flow covers and sprays the bottom of the vehicle, that is, the uniformity of water flow spraying the bottom of the vehicle is improved, and the cooling and fire extinguishing efficiency is effectively improved.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
