Including ring pipe, nozzle and connector, the outlet wall of casing is equipped with several cord hole, and binding rope passes through cord hole and ties up ring pipe
To casing outlet, the ring of ring pipe is equipped with several nozzles, and the outlet-inclined impeller vane of nozzle is towards the center of ring pipe, the outlet of nozzle
The export direction axis of direction and blower is in an acute angle, and ring pipe is equipped with a water inlet, and water inlet is one section of cylindrical tube, water inlet
Perpendicular to blower axis, water inlet is equipped with one section of external screw thread for mouthful axis, connector include extinguishing pipe connection screw thread, clamping head and
Ring pipe connection screw thread, extinguishing pipe connection screw thread and ring pipe connection screw thread are separately positioned on the both ends of clamping head, and ring pipe connects
Screw thread is connect to be threadedly coupled with water inlet.
The caliber of general fire extinguisher canvas hose is larger, and the caliber of the ring pipe of the present apparatus considers for small and exquisite portable wait of device
The big caliber not as accomplishing fire extinguisher canvas hose, so being used as switching using a connector, fire extinguisher canvas hose is connected through a screw thread
Extinguishing pipe connection screw thread on to connector, the high pressure water in fire extinguisher canvas hose is sent into ring pipe, by several sprays on ring pipe
Mouth sprays, and the nozzle positioned at air inlet sprays water mist, cools down to blower air inlet region, prevents high temperature air from entering wind
Danger is caused in machine region, and the water mist that the nozzle for being located at fan outlet sprays then blows to farther place by blower, to one
Region carries out cooling isolation.Because the present apparatus is designed primarily to fire-fighting purposes, and fire-fighting scene be often it is not electric, largely
It is also very dangerous using exposed plug, wiring board etc. under water vapour environment, so the drive part of the blower of the present apparatus is replaced
It for diesel engine, refuels in diesel engine, when use starts diesel engine, powers without drag cable.Present apparatus blower
The motor of the blower is changed to model for example using the blower of such as model T35-11-5 by fan leaf modular construction etc.
The small diesel engine of 170FW.The export direction of nozzle and the export direction axis of blower are in an acute angle, the water that such nozzle sprays
Mist is superimposed the wind-force of blower blowout to greatest extent, can be blown toward far.
Further, bottom support frame includes bottom support plate, universal wheel and height adjustment assembly, connects machine at the top of the support plate of bottom
The outside wall surface of shell, bottom support plate bottom both ends are respectively equipped with universal wheel and column are turned up, and are equipped with universal wheel below the support plate one end of bottom,
The other end, which is equipped with, is turned up cylinder, and the cylinder axis vertical of cylinder is turned up, and cylinder side is turned up and is equipped with fastening thread hole, fastening thread hole is logical
Hole, height adjustment assembly include that column, collet and fastening screw is turned up, and height-regulating mast axis is vertical, and column bottom is being turned up in collet setting,
Column insertion is turned up to be turned up in cylinder, fastening screw screws in fastening thread hole, and fastening screw screw head is pressed on the circle that column is turned up
On cylinder.
Universal wheel can be convenient people and drag the present apparatus, and height adjustment assembly then can be convenient user and adjust going out for blower
Bicker degree, the local bottom surface that the present apparatus uses is not usually horizontal or rugged, if the bottom support plate of side uses two wheels
Sub (i.e. device uses four wheels in total) is used to if supporting, if ground is not horizontal, the outlet of blower not be upward
It is that downward, misalignment needs the position of spray cooling, so two wheels of removal use two height-regulating columns instead, unclamps fastening screw,
Column will be turned up and haul sliding in height-regulating cylinder, after fan outlet is adjusted to proper angle, tighten fastening screw, column is turned up and is being turned up
It can not just be slided again in cylinder.
