[0029] By adopting the air suction mode to suck the flame at the fire position downward, the flame burning height and the flame burning range are quickly reduced, the flame burning is conveniently and quickly limited, the burning object is conveniently exposed, so that the direct covering of the water sprayed out of the diffusion spray head 5 is combined, the object is conveniently and directly cooled and flame-retardant treated, the fire is quickly and directly extinguished by the upper and lower cooperation, the fire extinguishing speed is effectively improved, the property loss is reduced, and the personnel such as the driver of the mine car is conveniently and effectively protected, and the safety is improved.

[0030] Preferably, as Figure 1 shown, it further comprises a suction pipe 6, the suction pipe 6 is annular, a plurality of suction holes 7 are arranged on the suction pipe 6, and the input end of the first high-temperature-resistant pipe 3 is communicated with the suction pipe 6.

[0031] Specifically, the suction pipe 6 is installed on the outside of the position prone to fire on the mine car, when the first high-temperature-resistant pipe 3 sucks air, the first high-temperature-resistant pipe 3 can suck the air around the burning position into the suction pipe 6 through the suction pipe 6 and the plurality of suction holes 7 thereon, so that a wind-driven isolation layer is formed on the outside of the burning position, the flame is conveniently confined within the suction pipe 6, and the fire spread is avoided.

[0032] Preferably, as Figures 1 to 2 shown, the water tank 1 is provided with an adjusting arm 8, the adjusting arm 8 is connected with the diffusion spray head 5, and the adjusting arm 8 is used to push the diffusion spray head 5 to move.

[0033] The adjusting arm 8 comprises a rotating column 9 rotatably mounted on the side wall of the water tank 1, a water guide pipe 10 fixed on the rotating column 9, a sliding sleeve pipe 11 slidably sleeved outside the water guide pipe 10, the sliding sleeve pipe 11 being in communication with the water guide pipe 10, a fixed disc 12 fixed at the outer end of the sliding sleeve pipe 11, a buckle groove plate 13 rotatably buckled on the fixed disc 12, an extension pipe 14 provided on the buckle groove plate 13 and in communication with the sliding sleeve pipe 11, and the diffusion spray head 5 mounted at the outer end of the extension pipe 14.

[0045] Specifically, in the natural state, the second water guide 29 is staggered with the first water guide 28, at this time, the diffusion nozzle 5 is in the retracted state, the sliding sleeve 11 is disconnected with the extension pipe 14, and the water in the water tank 1 cannot flow into the diffusion nozzle 5 naturally, thereby avoiding the water in the water tank 1 from flowing out of the diffusion nozzle 5 naturally due to the water level difference when the diffusion nozzle 5 is in the retracted state. When the buckle slot plate 13 rotates on the fixed disc 12 and the second water guide 29 is communicated with the first water guide 28, the sliding sleeve 11 is communicated with the extension pipe 14, at this time, the water in the sliding sleeve 11 can flow into the extension pipe 14 through the first water guide 28 and the second water guide 29, thereby realizing the water spraying work of the diffusion nozzle 5.

[0046] By making the width of the first water guide 28 larger than that of the second water guide 29, the buckle slot plate 13 can still rotate by a specified angle when the second water guide 29 is communicated with the first water guide 28, at this time, the extension pipe 14 is kept in the communicated state with the sliding sleeve 11, thereby realizing the multi-directional water spraying work of the diffusion nozzle 5.

[0047] Preferably, as shown, Figure 1 As shown, the water tank 1 is provided with a pressure relief valve 30 at the top.

[0048] Specifically, when the air pressure in the water tank 1 exceeds the specified value of the pressure relief valve 30, the air in the water tank 1 can be discharged naturally through the pressure relief valve 30, thereby forming a fixed pressure state in the pressure relief valve 30, ensuring the continuous and stable water spraying work of the diffusion nozzle 5, and avoiding the continuous increase of the spraying distance of the diffusion nozzle 5 due to the continuous increase of the pressure.

[0049] The above description is only the preferred embodiments of the present application, and it should be pointed out that those skilled in the art can make several improvements and modifications without departing from the technical principles of the present application, and these improvements and modifications should also be considered as the protection scope of the present application.
