Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1, the utility model discloses an air flow boosting type remote fire-fighting foam gun, which comprises a fan, a fan housing, a fan fairing, a foam mixed liquid input pipe, a foam nozzle and a foam cylinder, wherein the fan is fixed in the fan housing 1, the front end of the fan housing 1 is communicated with the fan fairing 2, the foam mixed liquid input pipe is divided into a left input pipe 16 and a right input pipe 17, one end of the left input pipe 16 penetrates from the left side of the fan fairing 2 and then is communicated with the liquid inlet end of the foam nozzle 4 positioned in the fan fairing 2, one end of the right input pipe 17 penetrates from the right side of the fan fairing 2 and then is also communicated with the liquid inlet end of the foam nozzle 4 positioned in the fan fairing 2, the other end of the left input pipe 16 and the other end of the right input pipe 17 are exposed outside the fan fairing 2 and are communicated with a foam mixed liquid supply pipeline, the liquid spraying end of the foam nozzle 4 is embedded in the foam cylinder 5, the foam cylinder 5 is fixed at the top end position inside the fan fairing 2;
the fan comprises a fan impeller 6, a fan oil motor 7 and a fan rectifier 8, wherein the center of the fan impeller 6 is connected with the fan oil motor 7 through a rotating shaft, and the fan oil motor 7 is fixed inside the fan rectifier 8.
Referring to fig. 2, the utility model discloses well fan radome fairing 2 utilizes pitch flexible hydro-cylinder 9 to be connected with rotary table 14, fan housing 1 utilizes support 10 to be connected with rotary table 14, and rotary table 14 is fixed mutually with the control pivot of gear wheel 11, and gear wheel 11 meshes with pinion 12, and the central authorities of pinion 12 are fixed mutually with the driving shaft of horizontal gyration oil motor 13, and the cylinder body of horizontal gyration oil motor 13 is then fixed at fixed mesa 15 upper surfaces.
