Abstract
The invention belongs to the fire extinguishing machinery technical field, and especially relates to a hand-operated type portable fire extinguisher. The hand-operated type portable fire extinguisher solves the problems of high making cost and difficult repeated usage of the traditional portable high pressure fire extinguishers. left and right belts are used for fixing a fire extinguisher cavity on the human body, the inner side is attached on the front part of the chest, a rocking bar is rotated for driving a transmission mechanism, thereby high pressure wind power conveying is employed to mix the extinguishing chemical with air having certain pressure for injecting from the cavity. The fire extinguisher fully combines a human engineering principle, the user can smoothly carry the fire extinguisher on the human body and use the hand-operated driving. Compared with the traditional fire extinguisher using a high pressure gas cylinder, the fire extinguisher uses a common plate as a material, the cost is low, the processing is simple, the fire extinguisher enables reliable and safe usage, the condition that the content leakage generated by the traditional high pressure fire extinguisher can lead to unusable fire extinguisher and user safety harm can be avoided; and the user can automatically add an extinguishing chemical for repeated multitime usage. The hand-operated type portable fire extinguisher can be widely popularized to indoor fire-fighting.
Description
Technical field
The invention belongs to the fire-fighting machine technical field, particularly the portable fire extinguisher of a kind of hand-rail type.
Background technology
We have following several by present indoor portable hand held fire extinguisher commonly used: portable aqueous film forming foam fire extinguisher; Portable dry powder fire extinguisher; Portable carbon dioxide extinguisher; 1121 hand fire extinguishers etc.According to the character of fire, the portable hand held fire extinguisher has its corresponding fire extinguishing scope of application.The principle of the hand fire extinguisher that these are traditional is all generally with firing-fighting medium (for example aqueous film forming foam, dry powder, carbon dioxide, alkyl halide) and Compressed Gas (nitrogen or compressed air) is same stores in cylinder body of fire extinguisher, and firing-fighting medium is ejected fire extinguishing by the pressure-driven of Compressed Gas.Due to the existence of gases at high pressure, so material and its processing method of fire extinguisher device bottle had certain requirement, make its cost high.In addition due to leave unused for a long time indoor need not, might compressed gas know from experience and reveal, can not play the effect of fire extinguishing when causing real breaking out of fire.A maximum deficiency of fire extinguisher commonly used can not be reused exactly at last.So we are necessary to research and develop a kind of with low cost, good sealing effect, can repeatedly add the portable fire extinguisher of Novel hand-operated machinery of extinguishing chemical.
Summary of the invention
The objective of the invention is that traditional portable high-pressure extinction device cost of manufacture is high, problem that can't Reusability in order to solve, provide a kind of hand-rail type portable fire extinguisher, 2 of left and right braces 10 is used for fire extinguisher cavity 8 is fixed on upper body, its inboard is attached to the front, rocking bar 4 is used for drive transmission device, thereby adopts high pressure wind-force to carry the air that extinguishing chemical 20 is mixed certain pressure intensity to eject from cavity 8.
The external agency of the portable fire extinguisher of described hand-rail type is, the two ends, left and right are inboard, are welded with 4 draw rings 9 from top to bottom, and particular location is decided according to base of principle of human engineering and user's build size; Cavity 8 outsides, upper end are connected with upper driving wheel gripper shoe 15.Cavity 8 upper ends are provided with feeding door 7, be used for to be used for injecting extinguishing chemical 20 to fire extinguisher in all.
Described transmission mechanism mainly comprises 3 band base bearings 6, upper driving wheel 13, impeller shaft 3, lower driving wheel 12, chain 5 and rocking bars 4.3 band base bearings 6 are fixed in respectively upper driving wheel gripper shoe 15, and the left and right sides, lower end symmetric position; Upper driving wheel 13 connects the band base bearing 6 on right side, upper end by the wheel hub that is welded thereon, and moves left and right by upper driving wheel locating part 14 restrictions of upper driving wheel 13 centers; The two ends of impeller shaft 3 are fixed in respectively on the band base bearing 6 of the left and right sides, lower end, and impeller shaft 3 stretches out with lower driving wheel 12 formation keys to right-hand member and is connected; Upper driving wheel 13 all adopts sprocket wheel with lower driving wheel 12, and number of teeth ratio is 2:1 ~ 3:1, consists of the chain transmission by chain 5; Rocking bar 4 one ends be welded in its center equal with upper driving wheel 13, the other end is welded with the handle of left and right directions; Be welded with some impellers 2 perpendicular to impeller shaft 3 in cavity 8 one section of impeller shaft 3, when rocking bar 4 is rotated, can impeller 2 rotate.
The internal mechanism of the portable fire extinguisher of described hand-rail type is, the downward-sloping centre that is arranged on cavity 8 of controllable register 18 is divided into up and down two parts with cavity 8, top is divided into for the extinguishing chemical bucket that stores extinguishing chemical 20, and the bottom is divided into for installing carries the also impeller mechanism of spray fire extinguishing agent 20.The top of controllable register 18 is with it parallel extinguishing chemical baffle plate 19, and extinguishing chemical baffle plate 19 is welded in cavity 8, and the duct that can supply extinguishing chemical 20 to pass through is left in the inboard; The below of controllable register 18 is arc plate 17, and arc plate 17 also is welded in cavity 8, is used for preventing that extinguishing chemical 20 from flowing into the dead angle of impeller top when spraying, and supports simultaneously controllable register 18.The protruding cavity 8 of controllable register 18 also is equipped with alignment pin in the outside of cavity 8, need to make when spraying fire extinguisher controllable register 18 is pulled out and located, thereby extinguishing chemical 20 is flowed down; The centre position that the outside of cavity 8 is positioned at controllable register 18 and extinguishing chemical baffle plate 19 is air inlet 1, and lower end, the place ahead is gas outlet 16; On the extinguishing chemical bucket on some hoppers duct 21 communicate with outside air, form negative pressure in the extinguishing chemical bucket when being used for avoiding extinguishing chemical 20 ejection.
