Abstract
The invention relates to the technical field of fire-fighting water cannon, in particular to a long-ranged vehicle-mounted fire-fighting water cannon. The water cannon comprises a horizontal rotary part and a pitching rotary part mainly formed by pipes with the same diameter and different radius of curvature and a pitching rotary joint. The water cannon is characterized in that: the pitching rotary part is connected with the other end of the pitching rotary joint and then bent along the counterclockwise direction of the pitching rotary joint and connected with a cannon head, and the pitching rotary part adopts the connection of the pipes with large radius of curvature. Compared with the prior art, the cannon pipe formed by the pipes of the pitching rotary part is counterclockwise arranged along a horizontal rotary joint, and the original bent pipes with 90-degree tail end is changed into smoothly bent flow channels with larger radius of curvature, which makes the high-speed water flow entering the nozzle of the cannon head of the water cannon evenly flow, thereby improving the fire-fighting range, reducing the operating moment required by the pitching rotation, lowering the operating intensity of fire fighters in fire fighting, reducing the power of the matching motor and reducing the water supply matching power of the water source required by the corresponding fire-fighting range by more than 60 percent.

[specific embodiment]
Below the invention will be further described, the present invention is still more clearly for the people of this professional skill field.
This far range vehicle-loaded fire-fighting fire-nozzle can be fixed by the horizontal rotation seat of horizontal rotation joint bottom according to the environment needs, the direct current generator 4 of horizontal rotation joint 1 and pitching rotary joint 3,11 are connected on the sequence control element of control cabinet, as the PLC controller, encoder or relay etc., control cabinet can be fixed in 12 ones on big gun head, drive direct current generator 4 by control cabinet, 11 rotate, thereby drive the gyration of control horizontal rotation joint 1 and pitching rotary joint 3, and then the rotation of control horizontal rotation portion and pitching rotary part, when control cabinet is malfunctioning, then by handwheel 1-2,3-2 drives horizontal rotation joint 1 and rotates with pitching rotary joint 3, does and horizontally rotates or elevating movement thereby drive in horizontal rotation portion and the pitching rotary part the formed gun tube of each radius of curvature pipe fitting.
The horizontal rotation angle of the horizontal rotation portion of horizontal rotation joint control is at+135 °～-135 °, is-15 °～+ 75 ° by the angle of pitch of the pitching rotary part of pitching rotary joint control.
Because gun tube is arranged counterclockwise along horizontal axis of rotation, and the bend pipe of gun tube becomes the broad warp runner than larger radius of curvature, make the high-velocity flow speed that enters water cannon big gun head nozzle be tending towards evenly having improved the fire extinguishing range, also reduced to do the required operating physical force distance of pitching revolution.
This fire water monitor can be widely used in water base fire fighting vehicle, under the situation that existing fire fighting truck chassis power does not increase, significantly improves the ejecting extinguishing fight capability of fire fighting truck.
