By the foregoing solution, the problem that the overall position of the existing fire - fighting water cannon is fixed and when fire - fighting operations need to be carried out at a distance, the spraying distance of the fire - fighting water cannon is insufficient, resulting in inconvenient use, is solved.

[0027] For this specific embodiment, the base 102 is fixedly connected to the connecting seat 101 and is located at the bottom of the connecting seat 101. The water inlet valve 103 is fixedly connected to the connecting seat 101 and is located on one side of the connecting seat 101. The pipe arm 104 is fixedly connected to the connecting seat 101 and is located at the top of the connecting seat 101. The muzzle 105 is arranged on one side of the pipe arm 104. When fire extinguishing is required, a water pipe can be connected to a fire hydrant, and the water inlet valve 103 is opened, so that water flows from the water pipe into the pipe arm 104 at the top of the connecting seat 101 and is ejected from the muzzle 105 on the side of the pipe arm 104 to extinguish the fire point. The connection method and usage method of the connecting seat 101, the base 102, the water inlet valve 103, the pipe arm 104 and the muzzle 105 are described in detail in the patent with the publication number CN212347518U, which is not within the protection scope of this application and will not be elaborated here.

[0028] Among them, the connecting cylinder 107 is fixedly connected to the base 102 and is located at the bottom of the base 102. The bottom plate 108 is fixedly connected to the connecting cylinder 107 and is located at the bottom of the connecting cylinder 107. The connecting frame 109 is fixedly connected to the bottom plate 108 and is located at the bottom of the bottom plate 108.

When a user needs to extinguish a fire, the moving wheel 110 on the connecting frame 109 can be started first. Through the rotation of the moving wheel 110, the fire hydrant on the connecting frame 109 is driven to move to a designated position as a whole. After moving to the designated position, the positioning stud 112 is rotated clockwise. The positioning stud 112 rotates downward on the bracket 111, pushing the limiting plate 113 to descend, so that the limiting plate 113 can abut against the ground, making the moving wheel 110 stop rotating, and the fire hydrant as a whole also stops at the designated position accordingly. At this time, the fire hose can be connected to the fire hydrant, and the water inlet valve 103 is opened, so that the water source in the fire hydrant enters the connecting cylinder 107 through the water pipe, flows from the connecting cylinder 107 into the pipe arm 104 on the connecting seat 101, and is ejected from the muzzle 105 on the pipe arm 104 to perform a water spraying operation on the fire location, thereby realizing fire extinguishing. After extinguishing the fire at one position, the user can rotate the positioning stud 112 counterclockwise. The positioning stud 112 starts to rise, driving the limiting plate 113 to rise, and then no longer abuts against the ground, facilitating the user to start the moving wheel 110. Through the rotation of the moving wheel 110, the fire hydrant is moved to the next fire extinguishing position, thus solving the problem that the position of the existing fire hydrant for fire fighting is fixed, and when fire extinguishing operations need to be carried out from a distance, the spraying distance of the fire hydrant is insufficient, resulting in inconvenient use.

[0029] Secondly, the placement rack 115 is fixedly connected to the bottom plate 108 and is located on one side of the bottom plate 108. The placement tray 116 is rotatably connected to the placement rack 115 and is located on the side of the placement rack 115.

After extinguishing the fire, the user can wind the water pipe around the placement rack 115 for fixation, and limit the placed water pipe by rotating the locking plate 117 to prevent it from scattering.

[0030] Again, the fixing bracket 118 is fixedly connected to the base 102 and is located on one side of the base 102. The connecting ring 119 is fixedly connected to the pipe arm 104 and is located on one side of the pipe arm 104. The fixing cylinder 120 is fixedly connected to the connecting ring 119, is slidably connected to the pipe arm 104, and is located on one side of the connecting ring 119. The handle 121 is fixedly connected to the connecting ring 119 and is located on the side of the connecting ring 119. During fire extinguishing, the user can hold the handle 121. According to the usage needs, by holding the handle 121, the connecting ring 119 is driven to start rotating on the fixing bracket 118, driving the pipe arm 104 to rotate accordingly, so as to adjust the water spraying position of the muzzle 105, facilitating the user's use.

[0031] For the fire fighting water cannon described in this embodiment, when the user needs to extinguish a fire, the moving wheels 110 on the connecting frame 109 can be started first. Through the rotation of the moving wheels 110, the entire fire fighting water cannon on the connecting frame 109 is driven to move to a designated position. After moving to the designated position, the positioning stud 112 is rotated clockwise. The positioning stud 112 rotates downward on the bracket 111, pushing the limiting plate 113 to descend, so that the limiting plate 113 can resist the ground, making the moving wheels 110 stop rotating, and the entire fire fighting water cannon also stops at the designated position accordingly. At this time, the fire fighting water pipe is removed from the placing disc 116 and connected to a fire hydrant, and the water inlet valve 103 is opened, so that the water source in the fire hydrant enters the connecting cylinder 107 through the water pipe, flows from the connecting cylinder 107 into the pipe arm 104 on the connecting seat 101, and is sprayed out from the muzzle 105 on the pipe arm 104 to perform a water spraying operation on the fire location, thereby realizing fire fighting. During the fire extinguishing operation, the user can hold the handle 121. According to the usage needs, by holding the handle 121, the connecting ring 119 is driven to start rotating on the fixing bracket 118, driving the pipe arm 104 to rotate accordingly, so as to adjust the water spraying position of the muzzle 105, facilitating the user's use. After extinguishing the fire at one position, the user can rotate the positioning stud 112 counterclockwise. The positioning stud 112 starts to rise, driving the limiting plate 113 to rise, and then no longer resisting the ground, facilitating the user to start the moving wheels 110. Through the rotation of the moving wheels 110, the fire fighting water cannon is moved to the next fire extinguishing position, thus solving the problem that the existing fire fighting water cannon is fixedly positioned as a whole, and when fire extinguishing operations need to be carried out from a distance, the water spraying distance of the fire fighting water cannon is insufficient, resulting in inconvenient use.
