Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a fire fighting water cannon. Background Art

[0002] Automatic fire-fighting water cannon can automatically monitor fires within the protection range around the clock. Once a fire occurs, the fire-fighting device is immediately activated, and an intelligent scan of the fire source in the horizontal and vertical directions is performed. After determining the two positions of the fire source, the water pump is started, the valve is opened, and the fire-fighting device is aimed at the fire source to spray water to extinguish the fire. Generally, automatic fire-fighting water cannons have at least two degrees of freedom, namely, horizontal rotation freedom and vertical rotation freedom. The horizontal rotation freedom is used to determine the horizontal position of the fire source, and the vertical rotation freedom is used to determine the vertical position of the fire source. The horizontal rotation and vertical rotation are achieved by motor drive. After searching, Chinese Patent Publication No. CN212090626U discloses an automatic fire-fighting water cannon with unlimited horizontal rotation, including a water inlet pipe, a collector ring, a horizontal motor plate and a horizontal motor. The horizontal motor plate is rotatably connected to the water inlet pipe; the horizontal motor is fixed to the horizontal motor plate, and the horizontal motor drives the horizontal motor. The plate rotates with the water inlet pipe as the axis; the collector ring includes an outer ring and an inner ring which are rotatably connected to each other, the water inlet pipe passes through the inner ring, and the water inlet pipe is fixed to the inner ring; the outer ring and the inner ring are conductively connected, and the outer ring and the inner ring are electrically connected to the horizontal motor and the power supply respectively. The shortcomings of the above patent are: first, a collector ring is fixed on the water pipe in the above patent. When the outer diameter of the water pipe is small, it is easy to cause insufficient water supply. When the outer diameter of the water pipe is large, the inner ring of the collector ring needs to be made very large, which increases the cost of use. Second, the water pipe passes through the collector ring, the horizontal motor plate and the bent pipe from top to bottom, resulting in a longer entire pipeline and a large space occupied. Third, the collector ring and the water inlet pipe gear are fixed on the water pipe, and the horizontal motor plate is rotatably connected to the water inlet pipe, which results in a larger bearing capacity of the water pipe, an easy deformation of the water pipe, a short service life of the water pipe and deformation of the water pipe that will affect the water supply.
