When the fire control rescue, the fire fighter is connected with fire hose joint 31 through connecting fire hose joint, and fire hose joint card goes into spacing groove 34 and rotates for fire hose joint and stopper 32 block avoid fire hose joint to drop.

When needs fire control work, fire pump motor 1 starts, the motor shaft drives the impeller and rotates, make suction rivers and flow into in the fire control interface in the fire control joint 31 of one side in the working chamber 21, the transmission through the impeller makes rivers pressure increase and discharges from the fire control interface in the opposite side fire control joint 31, carry out fire control work through fire hose and fire branch rifle, during the water pressure grow of flow in the fire control interface in the fire control joint 31, make supporting shoe 33 be close to fire control interface side cambered surface and rivers contact and pressurized towards stopper 32 direction removal, make supporting shoe 33 be close to stopper 32 side cambered surface part butt fire hose joint, for better to connect the position assurance connection of department between them, reach the stability when rivers transmit.

When a fire fighter is in fire rescue, the positions of the fire hose joints which are heavily deviated are respectively sensed through the pressure sensors 35 on the two sides, and then the pressure sensors 35 on the two sides are compared with each other to obtain different positions and angles to which the fire fighter can move the fire hose, meanwhile, the electromagnet 46 corresponding to the pressure sensor 35 on the side with high pressure is started to attract the handle 43 and drive the fixed block 44 to move, so that the first bevel gear on the speed reducing shaft 42 is in meshing transmission with one of the main bevel gears, and then the speed reducing shaft 42 rotates, through the meshing transmission between the second bevel gear and the third bevel gear on the speed reducing shaft 42, the spline sleeve 64 is further driven to rotate the spline shaft 61, so that the transmission power is reduced through the transmission main part 4 to reduce the rotating speed of the spline shaft 61, so that the telescopic sleeve 62 rotates in the fixed block 44, and then is meshed with the rack 63 through the gears on the spline shaft 61, so that the second blocking plate 66 drives the fire hydrant 31 to rotate to a desired angle.

Wherein the rotation angle of the second blocking plate 66 is determined by adjusting the steering direction of the reduction shaft 42 while the first bevel gear is in mesh transmission with the drive bevel gear at a different position.

When the spline shaft 61 rotates, the PLC controls the electric push rod 51 to start and contract, so that the electric push rod 51 is separated from the clamping groove 52, when the second baffle plate 66 rotates, the fire hose joint is monitored by the pressure sensor 35 all the time, when the values monitored by the pressure sensors 35 on the two sides are consistent, the PLC controls the electric push rod 51 to start again and clamp the electric push rod into the clamping groove 52 at the corresponding position, so as to ensure the stability of the fire hose joint and the fire connector 31 after rotating, avoid the water flow pressure change caused by the angle change between the impeller in the working cavity 21 and the fire connector 31 after rotating, further influence the stability during water flow transmission, and simultaneously ensure the fire hose connected with the fire connector 31, the pressure is not easy to change when the fire gun sprays water under the same water pressure, so that fire fighters do not need to change the grip constantly, the stability of the fire-fighting lance when the fire-fighting lance is held by hand is ensured, and the physical strength of fire fighters is saved.

And through adjusting 6 angle backs of adjusting fire joint 31 of main part, avoid the fire fighter to drive the fire hose and remove the back, the folding that probably takes place between fire joint 31 and the fire hose, because folding can influence normal water delivery, the rivers that flow in the fire hose are through folding position, the exhaust can lead to the water pressure increase in the twinkling of an eye, and after rotating corresponding angle through fire joint 31, can avoid the fire hose to drag the fire fighter and the fire branch that leads to takes off the hand, avoid delaying the fire rescue opportunity, influence the fire fighter and normally work.
