Detailed Description

In order to better understand the technical content of the present invention, the following embodiments are provided, and the present invention is further described with reference to the accompanying drawings.

Example 1

Referring to fig. 1, the anti-backward-moving device of the hand-lifting movable fire monitor comprises an underframe 1 and a support 2, wherein the support 2 is fixed on the underframe 1, the support 2 is used for being hinged to a fire-fighting spray gun 3, a support leg 4 is arranged on the underframe 1, an inverted cone-shaped tip 5 is arranged below the support leg 4, a telescopic rod 6 is arranged in the middle of the underframe 1, a suction cup 7 is arranged at the bottom of the telescopic rod 6, the top of the suction cup 7 is communicated with the fire-fighting spray gun 3 through a first pipeline 8, and a first valve 9 is arranged on the first pipeline 8.

The below of chassis 1 is equipped with

landing leg

4, and 4 below of landing leg are equipped with back taper point 5, can utilize the back taper point 5 of 4 below of landing leg to insert ground at earth ground and fix the back, utilize fire control spray gun 3 to spray water and put out a fire, support 2 is used for articulating with fire control spray gun 3, can adjust the water spray angle of fire control spray gun 3. When smooth hard ground, extend telescopic link 6, make sucking disc 7 press on ground and adsorb ground, can prevent that the device from shifting backward, solve landing leg 4 and can not insert ground and lead to preventing the not good problem of effect of shifting backward. Before adsorbing, can open first valve 9 for rivers in the fire control spray gun 3 are to sucking disc 7 in, clean totally in the sucking disc 7, can improve adsorption effect with sucking disc 7 ground position sanitization that will adsorb simultaneously. After cleaning, the first valve 9 is closed, and the sucker 7 is pressed on the smooth ground to suck the ground. Because the sucking disc 7 is filled with a small amount of water, the water can seal the gap between the sucking disc 7 and the smooth ground, so that air leakage is prevented, and the adsorption effect is improved. When the suction is not needed, the telescopic rod 6 is shortened, and the contact between the suction cup 7 and the ground can be avoided.

Specifically, the telescopic rod 6 is a vertical telescopic rod 6. The telescopic rod 6 stretches in the vertical direction, so that the sucker 7 can conveniently adsorb the smooth ground.
