Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting water cannons, in particular to a fire-fighting water cannon with a telescopic frame. Background Art

[0002] Fire water cannon is a fire-fighting equipment that uses water as a medium to extinguish fires at a long distance. This cannon is suitable for petrochemical enterprises, storage tank areas, hangars, warehouses, port terminals, garages and other places, and plays a very vital role in fire fighting.

[0003] At present, the height of existing fire-fighting water cannons is usually fixed, and firefighters need to bend over frequently to use them when working. Long-term operation of the water cannon increases the labor intensity of the staff. To solve such problems, the existing Chinese patent application number is 202320410439.6, which discloses a fire-fighting water cannon with a telescopic frame. The patent relates to a fire-fighting water cannon with a telescopic frame, comprising a base plate and a fixed box, an adjustment mechanism is provided on the base plate, an auxiliary positioning assembly is provided on the fixed box, the adjustment mechanism comprises a fixed seat fixedly mounted on the top of the base plate, a limit seat is fixedly mounted on the top of the fixed seat, the internal rotation of the fixed seat is connected with a rotating shaft, and the top of the rotating shaft is fixedly mounted with a limit plate movably connected to the limit seat. The fire-fighting water monitor with a telescopic frame has an adjusting mechanism and an auxiliary positioning component, and when the fire-fighting water monitor body is in use, the height of the fire-fighting water monitor body can be adjusted arbitrarily according to the height of the user through the cooperation between various structures, thereby improving the user's comfort and reducing the user's physical fatigue. The use angle of the fire-fighting water monitor body can be adjusted arbitrarily by means of hinges and rotations, thereby improving the use efficiency of the fire-fighting water monitor body and improving the practicality of the fire-fighting water monitor body.

[0004] Although the above-mentioned patent, through the mutual cooperation between various structures, makes the height of the fire monitor body arbitrarily adjustable according to the height of the user, improves the user's comfort, reduces the user's physical fatigue, and the use angle of the fire monitor body can be arbitrarily adjusted by hinge and rotation, but in actual use, the patent drives the tooth block to rotate by rotating the rotating rod, thereby causing the rack plate to move upward. At this time, since the fire monitor body is above the rack plate, and the weight of the fire monitor body is relatively heavy, such as the weight of the PS50 fire monitor model on the market is 123kg, this causes the rack plate to bear the entire weight of the fire monitor body, which makes it very laborious for the user to manually adjust the height of the rack plate, which is not conducive to people's use.

[0005] Therefore, it is necessary to modify the fire water monitor with telescopic frame in the above patent to effectively prevent the user from manually adjusting the height of the fire water monitor body with great effort, which is not conducive to people's use. Utility Model Content
