Abstract
The invention relates to a multi-function jet wind fire-extinguisher powered by a portable wind fire-extinguisher. The multi-function jet wind fire-extinguisher is characterized in that a nozzle, a negative pressure cavity, a choke and a diverging pipe are coaxially arranged at a wind outlet pipe of a blower, wherein the negative pressure cavity is communicated with a fire extinguishing agent storage tank through a fire extinguishing agent conveyer pipe, a control valve and a fire extinguishing agent suction pipe. By using the nozzle, the choke, the negative pressure cavity, the diverging pipe and the like which are specially designed, the wind fire-extinguisher can use multiple fire extinguishing agents, and each fire extinguishing agent is well mixed with air, thereby enhancing the fire extinguishing efficiency, and simultaneously enabling the wind fire-extinguisher to extinguish more kinds of fires.
Description
One, technical field
The invention belongs to Fire extinguisher apparatus, be specifically related to a kind of novel fire-extinguishing apparatus that utilizes the wind-force spray fire extinguishing agent to put out a fire.
Two, background technology
The geomantic omen spray of existing various band water injectors, as:
CN ZL 02274980.2 water jet wind fire-extinguisher;
CN ZL 200620068408.3 backpack geomantic omen sprays;
CN ZL 200820109686.8 powder/liquid wind fire-extinguishers
Deng, substantially all it is inner and send to the technical scheme at fire position after air-flow mixes to adopt auxiliary hose that air duct is introduced in the gravity flow of water or powder, the mixed effect of water and air is not ideal enough, can't use multiple extinguishing chemical to adapt to various dissimilar fire, therefore can only use in the common fire situation of minorities such as forestry.And use the fire extinguishing appliance of various different extinguishing chemicals, and then must use corresponding apparatus and technology such as pump, pressurization storage, corresponding extinguishing chemical could be transported to effectively the happening part of dissimilar fire.
Three, summary of the invention
The objective of the invention is at the mixed effect of water and air in the spray of existing various geomantic omen not ideal enough, can't use multiple extinguishing chemical to adapt to the deficiency of various dissimilar fire, design the better multi-function jet wind fire-extinguisher of a kind of mixed effect, enlarge can the put out a fire purpose of calamity kind of wind fire-extinguisher thereby when improving fire-fighting efficiency, reach.
Technical solution of the present invention is: a kind of multi-function jet wind fire-extinguisher that is used as power with portable wind fire-extinguisher is characterized in that:
A. locate coaxial installing nozzle (4), negative pressure cavity (5), trunnion (6) and anemostat (7) at blower fan discharge pipe (2);
B. negative pressure cavity (5) is connected with extinguishing chemical storage tank (10) by extinguishing chemical carrier pipe (8), control valve (9) and extinguishing chemical suction pipe (11).
Can single solid of can or liquid extinguisher in the extinguishing chemical storage tank (10), also extinguishing chemical storage tank (10) can be divided into several zones dissimilar solid or liquid extinguishers of cans respectively.Can select for use corresponding extinguishing chemical that it is conveyed into the fire extinguishing of carrying out different fire types in the shower nozzle by control valve (9) during the fire extinguishing operation.
Operation principle of the present invention is (referring to an accompanying drawing 1), at the blower fan discharge pipe (2) of existing wind fire-extinguisher locate to pack into the nozzle component of a particular design, blower fan in the wind fire-extinguisher produces the air-flow with certain flow and blast under the driving of internal combustion engine, when crossing the nozzle (4) of jet pipe, this air communication sharply shrinks, form great negative pressure near negative pressure cavity nozzle (5), extinguishing chemical in this negative pressure sucking-off storage tank (10), in trunnion (6), mix after anemostat (7) sprays at a high speed, thereby reach good fire extinguishing effect.
Four, description of drawings
Fig. 1 is the general structure schematic diagram of multi-function jet wind fire-extinguisher.(1) is internal combustion engine and blower fan among the figure, (2) be the blower fan discharge pipe, (3) are adpting flange and connector, and (4) are nozzle, (5) be negative pressure cavity, (6) be trunnion, (7) are anemostat, and (8) are the extinguishing chemical carrier pipe, (9) be control valve, (10) be the extinguishing chemical storage tank, (11) are the extinguishing chemical suction pipe, and (12) are universal wheel;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the nozzle component schematic diagram of multi-function jet wind fire-extinguisher.
Five, the specific embodiment
Embodiment 1:
As shown in Figure 1, the 6MF-28 type portable wind-power spray repacking that internal combustion engine and blower fan (1) directly use Linhai Power Machinery Co., Ltd., Jiangsu to produce, air output 0.5m
3/ s;
As shown in Figure 3, the physical dimension of nozzle component is as follows:
Jet angle α=28 °
Diameter D1=110mm; D2=60mm; D3=10mm; D4=14mm; D5=18mm; D6=62mm; D7=40mm;
Length L 1=40mm; L2=70mm; L3=125mm; L4=90mm; L5=250mm;
The volume of extinguishing chemical storage tank (10) is 30L, and whole can high-expansion foam extinguishing agents are adjusted the flow of extinguishing chemical by control valve (9), by extinguishing chemical suction pipe (11) fire foam are conveyed in the shower nozzle and put out a fire.
Embodiment 2:
As shown in Figure 2, extinguishing chemical storage tank (10) is separated into 4 distinct area, and is respectively charged into dissimilar liquid or solid extinguishing chemicals.Control valve (9) is a cross valve, 4 kinds of dissimilar liquid or solid extinguishing chemicals can by 4 suction pipes according to fire type, select for use corresponding extinguishing chemical that it is conveyed in the shower nozzle by control valve (9) to put out a fire.
The physical dimension of nozzle component is with embodiment 1.
Beneficial effect: because the present invention has adopted nozzle, trunnion, negative pressure cavity and the anemostat etc. of particular design, not only can use multiple extinguishing chemical, and various extinguishing chemicals and Air mixing are good, thereby having realized reaching when improving fire-fighting efficiency enlarges can the put out a fire purpose of calamity kind of wind fire-extinguisher.
Claims (2)
1. multi-function jet wind fire-extinguisher that is used as power with portable wind fire-extinguisher is characterized in that:
