High-lift forest fire pump

The high-lift forest fire pump comprises a fire pump body, a water outlet of the fire pump body is connected with a connecting pipe, the connecting pipe is connected with a water hose through a threaded connecting seat, a flow dividing structure is arranged at the position of the threaded connecting seat and comprises a pressure relief assembly, and the pressure relief assembly is communicated with a flow dividing pipe; the other end of the shunt pipe is communicated to a relatively distant water hose, and the shunt pipe enables the sleeve seat and the water hose to form a closed loop again; and a necking structure is arranged on the peripheral wall of the outer side end of the threaded connection seat. According to the fire pump, a multi-stage pressurizing fire pump body can be adopted, remote water supply is achieved through high-lift pumping, meanwhile, a flow dividing structure is arranged at the position of the connecting pipe to achieve the pressure relief effect, in other words, instant flow dividing a
