AI Technical Summary
Due to the low transmission efficiency of worm gear and worm, existing fire water cannons have low working efficiency, low fire extinguishing efficiency, and hard friction, which shortens their service life.
The transmission is carried out in conjunction with the motor gear, which eliminates the transmission of worm gear and worm gear, and a polytetrafluoroethylene bearing is installed between the sector gear and the rotating body to reduce friction.
It improves the working efficiency and fire extinguishing efficiency of fire water cannons, extends service life, and simplifies the structure without the need for additional limit switches.

Abstract
Description
Technical Field
[0001] The utility model relates to a fire-fighting device, in particular to a consumption level, belonging to the field of consumer goods. Background Art
[0002] Fire water monitor is a fire extinguishing equipment that uses water as a medium to extinguish fires at a long distance. This monitor is suitable for petrochemical enterprises, storage tank areas, hangars, warehouses, port terminals and other places, and is an ideal vehicle-mounted fire monitor for fire trucks. Fire water monitor consists of a base, a water inlet pipe, a rotating body, a water collecting pipe, a jet adjustment ring, a handle and a locking mechanism. The gun body can be rotated horizontally and in elevation, and can be positioned. The monitor has a wide range of pressure, a long range, and can implement stepless adjustment from direct current to 90° blooming and water mist jet.
[0003] The utility model patent with the publication number CN211705701U and the application name of a fire water cannon discloses a fire water cannon, in which the motor drives the cannon mouth to rotate through a turbine worm gear transmission. The fire water cannon occupies a large space, and the worm gear transmission efficiency is low. The low transmission efficiency leads to low working efficiency of the fire water cannon and low fire extinguishing efficiency. In addition, there is hard friction between the worm gear, which leads to a short service life of the fire water cannon. It is now necessary to propose a fire water cannon with a long service life and high fire extinguishing efficiency. Utility Model Content
[0004] The utility model aims at the deficiencies of the prior art and provides a fire-fighting water monitor which occupies a small area, has a simple structure and high working efficiency.
[0005] This fire-fighting water cannon has a cover body that is buckled onto the rear of the cannon body, and a water diversion body, a vertical motor and a nozzle that are fixedly installed between the cover body and a support plate. The water diversion body is located above the vertical motor and the nozzle, and the fan gear is fixedly connected to the rotating body of the nozzle, and the fan gear is meshed with the motor teeth of the vertical motor.
[0006] Further optimization is performed, in which the central axis of the motor teeth of the vertical motor is parallel to the central axis of the nozzle rotating body, which greatly reduces the volume of the gun body.
[0007] Further optimization is performed by installing a polytetrafluoroethylene bearing between the sector gear and the rotating body.
[0008] Further optimization, the sector angle of the sector gear is 120°.
[0009] The advantages of the utility model are: the fire water monitor adopts the sector gear and the motor gear to transmit the power, eliminating the worm gear transmission, high working efficiency, small wear and tear, and long service life of the fire water monitor; the structure is simple and no additional limit switch is required.

[0013] The fire water monitor will be further described below in conjunction with the accompanying drawings.
[0014] like Figure 1 , Figure 2 As shown, this fire-fighting water cannon has a cover body buckled on the rear of the cannon body, a water-dividing body 1, a vertical motor 2 and a nozzle fixedly installed between the cover body and a support plate 3, a water-dividing body 1 is located above the vertical motor 2 and the nozzle, a fan-shaped gear 5 is fixedly connected to the rotating body of the nozzle, the central axis of the motor teeth 4 of the vertical motor 2 is parallel to the central axis of the nozzle rotating body 7, the installation of the vertical motor 2 changes the original installation position of the motor, the central axis of the motor is perpendicular to the central axis of the nozzle, the motor and the nozzle are respectively installed on both sides of the support plate 3, and the installation method is now that the vertical motor 2 and the nozzle rotating body 7 are installed on one side of the support plate 3, which greatly saves space and reduces the volume of the fire-fighting water cannon. The fan-shaped gear 5 is meshed with the motor teeth 4 of the vertical motor 2, the fan-shaped angle of the fan-shaped gear 5 is 120°, the motor teeth 4 of the vertical motor 2 drive the fan-shaped gear 5 to rotate, the fan-shaped gear 5 drives the nozzle rotating body 7 to rotate, thereby driving the nozzle to drive and realize fire extinguishing. In order to increase the transmission efficiency and reduce the friction, a polytetrafluoroethylene bearing 6 is installed between the fan-shaped gear 5 and the rotating body.
