A water hose reel for a fire-fighting motorcycle

Abstract

The invention discloses a water hose reel for a fire-fighting motorcycle, which comprises a water inlet elbow. Hose connector, the right end of the hose connector is clamped with a hose, the hose passes through the waist-shaped hole on the outer surface of the reel and is wound on the outer surface of the reel, the hose connector is placed inside the reel, and the left and right ends of the reel are The baffle is fixedly connected by the baffle connecting screw, the right end of the reel is provided with a rotating shaft, and the right end of the rotating shaft is clamped with a hand wheel. The shaft is fixedly connected, the right end of the U-shaped rack is fixedly connected with the rotating shaft through the rack fixing device, the left side of the U-shaped rack is connected with an anti-rotation bracket through bracket fixing screws, and the other end of the anti-rotation bracket is fixedly connected to the water inlet elbow , The right side of the U-shaped frame is also provided with an anti-rotation latch assembly.

Description

technical field [0001] The invention relates to the technical field of fire-fighting motorcycles, in particular to a water hose reel for fire-fighting motorcycles. Background technique [0002] Existing fire-fighting motorcycle water hose reels, due to the limitations of the vehicle structure, all adopt such image 3 In the structure shown, in this structure, the water flows into the hose 7 through the water inlet joint 22, the central joint 23, the water inlet elbow 24, the water outlet elbow 25, etc., and there are three 90° right-angle elbows with a large resistance coefficient , especially the connection between the water inlet joint 22 and the central joint 23 through four small radial holes with a diameter of 3 mm, the flow cross section is too small, and the water flow reaches the end of the 30-50-meter hose 7 (connected to the atomizing spray gun ), the interface water pressure is low (pressure loss above 0.60MPa), which seriously affects the atomization effect and f...
