Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting, and particularly relates to a multi-agent combined central rotating body. Background Art

[0002] A Chinese patent with the authorized publication number of "CN103751934B" and the name of "Multi-agent combined central rotating body device" discloses a multi-agent combined central rotating body device, which includes: a fixed turntable frame, a rotating table rotatably arranged on the turntable frame, and the rotating table is driven by a driving device to rotate on the turntable frame; the rotating part of the central rotating body is fixedly connected to the rotating table, and the fixed part of the central rotating body is fixedly connected to the turntable frame; the rotating part of the central rotating body includes an outer output pipe, an inner output pipe coaxially arranged in the inner cavity of the outer output pipe, and a rotating valve body fixedly connected to the outside of the outer output pipe; the fixed part of the central rotating body includes an inner input pipe sleeved outside the inner output pipe and an outer input pipe correspondingly sleeved outside the outer output pipe, and sealing rings are arranged between the pipe walls of the inner output pipe and the inner input pipe, and between the pipe walls of the outer output pipe and the outer input pipe. This patent can convey one kind of fire extinguishing agent, and can also convey a combination of two or more fire extinguishing agents at the same time.

[0003] The above patent can convey a combination of multiple fire extinguishing agents at the same time, so as to achieve a better fire extinguishing effect. In actual use of the rotating body of the above patent, in order to meet different installation requirements, the inner input pipe and the outer input pipe are often arranged in a cross manner, which makes it difficult to install the inner output pipe inside the outer output pipe. Moreover, the outer output pipe of this patent is too long and requires multi-section welding processing. Since welding will change the properties of the welding part, in the long-term use, fire extinguishing agent will penetrate from the inside, reducing its service life and seriously affecting the fire extinguishing effect of fire fighting.
