[0025] Referring to Figures 1 to 3 , the sprinkler of the first aspect embodiment of the present utility model includes: a main body 100, provided with a first connecting pipe 111 and a second connecting pipe 112, the first connecting pipe 111 is used to connect to a water supply, and the second connecting pipe 112 is used to dock with the first connecting pipe 111 of another main body 100; a spraying mechanism, including a rotating pipe fitting and a water outlet pipe, the water outlet pipe is rotatably arranged on the main body 100 through the rotating pipe fitting, one end of the rotating pipe fitting is communicated with the main body 100, and the other end of the rotating pipe fitting is communicated with the water outlet pipe; wherein, the water outlet pipe is provided with a plurality of nozzles 213, and the nozzles 213 spray water obliquely upward.

[0026] By sending the sprinkler underground of the on - fire vehicle and introducing high - pressure water flow, after the water flow enters the main body 100, it is sprayed out from the water outlet pipe through the rotating pipe fitting. The nozzles 213 spray water obliquely upward, causing the water outlet pipe to rotate, improving the sprinkling effect, reducing the battery temperature, and at the same time extinguishing the fire source on the battery, improving the fire - extinguishing efficiency of new energy vehicles. And through the first connecting pipe and the second connecting pipe, multiple such sprinklers are connected together, enabling multiple such sprinklers to start spraying water simultaneously, further improving the fire - extinguishing effect.

[0027] It can be understood that, with reference to Figures 1 to 3 , the rotating pipe fitting includes a positioning pipe 230, a movable pipe 220 and a limiting member 240. The positioning pipe 230 is welded to the main body 100 and communicates with the main body 100. The movable pipe 220 is sleeved in the positioning pipe 230. The limiting member 240 is threadedly connected to the positioning pipe 230 and is sleeved between the positioning pipe 230 and the movable pipe 220. The water outlet pipe is threadedly connected to the movable pipe 220. There is a seal between the positioning pipe 230 and the movable pipe 220, so that no water leaks when the movable pipe 220 rotates in the positioning pipe 230. At the same time, the movement of the movable pipe 220 along the axial direction is restricted by the limiting member 240 to prevent the movable pipe 220 from falling out.

[0028] Specifically, with reference to Figure 2 and Figure 3 , the water outlet pipe includes a connector 211 and a plurality of spray pipes 212. The connector 211 is threadedly connected to one end of the movable pipe 220. The plurality of spray pipes 212 are all connected to the connector 211. The plurality of spray pipes 212 are arranged circumferentially. The nozzle 213 is provided on the pipe wall of the spray pipe 212. Water flows from the main body 100 through the connector 211 into the spray pipes 212, and then sprays out from the nozzles 213. The plurality of spray pipes 212 are arranged circumferentially, so that the thrust generated after the nozzles 213 spray water drives the movable pipe 220 to rotate, realizing rotary water spraying.

[0029] It can be understood that, with reference to Figure 2 and Figure 3 , a first limiting portion 221 is provided at one end of the movable pipe 220. A first sealing ring 251 is sleeved on the movable pipe 220. The first sealing ring 251 is provided between the first limiting portion 221 and the connector 211. By threadedly connecting the connector 211 to the movable pipe 220, the tightening direction of the connector 211 is the same as the rotation direction of the connector 211, avoiding loosening of the connector 211. When the connector 211 is tightened, the end portion of the connector 211 drives the first sealing ring 251 to abut against the first limiting portion 221, so that the first sealing ring 251 is closely attached to the first limiting portion 221 and the end portion of the connector 211 respectively, avoiding water leakage at the connector 211.

[0030] It can be understood that, with reference to Figure 2 and Figure 3 , a second limiting portion 241 protrudes from the outside of the limiting member 240. The second limiting portion 241 can abut against the end portion of the positioning pipe 230. By abutting the second limiting portion 241 against the end portion of the positioning pipe 230, the positioning of the limiting member 240 is realized, the movement stroke of the limiting member 240 is restricted, and the connection stability is improved.

[0031] It can be understood that, with reference to Figure 2 and Figure 3, a sealing member is sleeved outside the movable pipe 220. The movable pipe 220 is provided with a third limiting portion 222. The limiting member 240 drives the sealing member to abut against the third limiting portion 222, and the sealing member abuts against the inner wall of the positioning pipe 230. After the limiting member 240 extends into the positioning pipe 230, by driving the sealing member to abut against the third limiting portion 222, while achieving sealing, it can also prevent the movable pipe 220 from slipping out. In addition, when the movable pipe 220 slides down, the first sealing ring 251 enters into the limiting member 240, and by abutting against the inner wall of the limiting member 240 through the first sealing ring 251, water leakage between the movable pipe 220 and the limiting member 240 is avoided.

[0032] It can be understood that, referring to Figure 2 and Figure 3 , the sealing member includes a second sealing ring 252 and two third sealing rings 253. The two third sealing rings 253 are respectively arranged on both sides of the second sealing ring 252. The second sealing ring 252 abuts against the inner wall of the positioning pipe 230, and the two third sealing rings 253 respectively abut against the limiting member 240 and the third limiting portion 222. Through the cooperation of the second sealing ring 252 and the third sealing ring 253, the sealing between the movable pipe 220 and the positioning pipe 230 is achieved. The limiting member 240 and the third limiting portion 222 cooperate to squeeze the second sealing ring 252 and the third sealing ring 253, causing the second sealing ring 252 and the third sealing ring 253 to deform, so that the second sealing ring 252 fits against the inner wall of the positioning pipe 230, and at the same time the third sealing ring 253 fits against the side wall of the movable pipe 220, improving the sealing effect.

[0033] It can be understood that, referring to Figure 1 , the main body 100 is provided with a base 121. The base 121 is provided with a plurality of support plates 122 in the horizontal direction, so as to improve the stability of the main body 100 when the water outlet pipe rotates and prevent the main body 100 from tipping over.

[0034] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art to which it pertains, various changes can be made without departing from the gist of the present invention.
