[0032] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:
[0033] In use, water is introduced into the water tank 2 through the inlet pipe 8. Turning on motor two 702 drives the lead screw 703 to rotate, causing the lifting frame 704 to axially rise and fall on the lead screw 703. During this movement, the lifting frame 704 drives the transmission box 707 and the nozzle 6 to rise and fall, allowing for height adjustment of the nozzle 6. Turning on motor three 711 drives the driving bevel gear 712 to rotate and mesh with the driven bevel gear 710, causing the driven bevel gear 710 to drive the rotating column 709 and the rotating seat 708 to rotate. The rotating seat 708 then drives the nozzle 6 to rotate left and right, allowing for adjustment of the left and right spray angle of the nozzle 6. Turning on motor four 713 drives the rotating rod 714 and the nozzle 6 to rotate up and down, allowing for adjustment of the up and down spray angle of the nozzle 6. The nozzle 6 can be adjusted to aim at the fire-fighting position. The pump body 4 draws water from the water tank 2 into the extraction pipe 5 through the water extraction pipe 10, then into the cavity 303, and finally into the nozzle 6 through the water supply pipe 304. The water is then sprayed out at the fire source by the nozzle 6 to extinguish the fire. When the fire-fighting equipment is not in use and the water supply pipe 304 needs to be wound up, the motor 306 is turned on to drive the transmission gear 307 to rotate and mesh with the gear sleeve 305. This allows the gear sleeve 305 to drive the winding roller 302 to rotate and wind and sun to wind up the water supply pipe 304. This avoids the problem of the water supply pipe 304 being exposed for a long time, which can easily lead to the water supply pipe 304 breaking. It also avoids the problem of the water supply pipe 304 being exposed and messy, which can affect the movement of the fire-fighting equipment.
