Problems solved by technology
[0002] The fire-fighting water cannon uses water as the medium to extinguish the fire from a long distance. The traditional fire-fighting water cannon generally adjusts the spray angle of the fire-fighting water cannon through a handle. Personnel maintain a certain movement with their hands for a long time to extinguish the fire in a specific area. Such a long work will inevitably bring more physical energy consumption to the firefighters.

The invention discloses an angle adjustable large space fire water cannon. A cannon body, a water inlet pipe, a base and a nozzle are included. A pair of support arms and a pair of first support lugsare fixed to the base. A pair of support arms are hinged to a hinge base fixed to a rotation table. A drive shaft is hinged between a pair of second support lugs on the rotation table. A first bevel gear is fixed to the drive shaft. A hinge part is hinged to the middle portion of the drive shaft and hinged to a support shaft. A second bevel gear engaged with the first bevel gear is fixed to the support shaft. The right end of the support shaft is in screw joint with a T-shaped rod, and the T-shaped rod is hinged to the first support lugs. The rotation table is hinged to the base, a gear ring is fixed to the base, and the gear ring is engaged with an arc rack, wherein the arc rack is inserted in the rotation table in a sleeved manner and can move up and down. By means of the angle adjustable large space fire water cannon, the spraying angle of the water cannon can be adjusted and can be kept for spraying, and the angle adjustable large space fire water cannon can adapt to firefighting work under different work conditions.
Description
Technical field: [0001] The invention relates to the technical field of fire-fighting equipment, in particular to an angle-adjustable fire-fighting water cannon for large spaces. Background technique: [0002] The fire-fighting water cannon uses water as the medium to extinguish the fire from a long distance. The traditional fire-fighting water cannon generally adjusts the spray angle of the fire-fighting water cannon through a handle. Personnel maintain a certain movement with their hands for a long time to extinguish the fire in a specific area. Such a long work will inevitably bring more physical energy consumption to firefighters. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a large-space fire-fighting water cannon with adjustable angle, which can adjust the spraying angle of the water cannon and spray at this angle, and can adapt to fire-fighting work in different working conditions . ...
