Abstract
The utility model discloses a self-protecting device for the chassis of a firefighting truck and relates to firefighting equipment. The self-protecting device comprises a self-protecting device body which is a three-way pipe; the three-way pipe is prepared from 1Cr23Ni13 stainless steel; the inner wall of the three-way pipe is provided with a rectangular groove; the inner wall of the end port of one end of the three-way pipe is provided with a spray nozzle, the end port is provided with a nut, and the nozzle is provided with step-like through holes; the end port of the end, close to the spray nozzle, of the three-way pipe is provided with a filter cover; the end port of the end, far away from the spray nozzle, of the three-way pipe is provided with a deflector which is arranged obliquely; and an included angle of 30-60 degrees is formed between the deflector and the vertical surface. The self-protecting device can spray both clear water and foam, thereby effectively improving the self-protecting function of the firefighting truck, so the self-protecting device is convenient and practical.
Description
Technical field
The present invention relates to a kind of fire-fighting equipment, relate in particular to a kind of self-protecting device for chassis of fire engine.
Background technology
Fire fighting truck is to put out a fire to save life and property necessity equipment of the fire such as oil, chemical industry, industrial enterprise, goods yard, harbour.These scene of fire danger are larger; have that burning velocity is fast, scene of a fire situation changes many, explosive combustion probability greatly and to fire fighting truck and combatant's the threat feature such as greatly; therefore fire fighting truck needs fire fighting truck to carry out necessary protection under by the scene of a fire or particular surroundings; existing fire fighting truck protective device is generally to utilize water pump to spray clear water put out a fire and lower the temperature; the method blow-off velocity is slow; efficiency is low, does not have the object of effective protection fire fighting truck itself.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of Novel fire-fighting truck self-protecting device for chassis, not only can spray clear water, can also spray foam, effectively improve fire fighting truck self-protection ability, and very convenient and practical.
Technical scheme of the present invention is: a kind of self-protecting device for chassis of fire engine, comprise automatic holding device body, described automatic holding device body is a three-way pipe, described three-way pipe adopts 1Cr23Ni13 stainless steel to make, three-way pipe inwall has rectangular channel, and three-way pipe wherein one end port inner wall is provided with nozzle, on this port, is provided with nut, on described nozzle, have ladder hole, three-way pipe is provided with filter mantle near one end port of nozzle; Three-way pipe is provided with deflector away from one end port of nozzle, and described deflector is obliquely installed, and the angle of itself and vertical plane is 30～60 degree.
As preferably, described automatic holding device body is Y-shaped three-way pipe, and described nozzle threads is connected in wherein one end port inner wall of three-way pipe, and described filter mantle is connected with three-way pipe by screw.
As preferably, described deflector is connected in three-way pipe away from one end port of nozzle by adapter sleeve, adapter sleeve is threaded with three-way pipe, and deflector is welded in adapter sleeve away from one end of three-way pipe, and the face that adapter sleeve is corresponding with deflector is arranged to the inclined-plane corresponding with deflector.
The invention has the beneficial effects as follows: the water that in automatic holding device body of the present invention, fully hybrid concurrency bubble enters from nozzle and foam mixing liquid and the air entering from filter mantle, via deflector, spray again, can rapid Cover flame, make material and the air insulated of firing, and reduce temperature, reach the object of quick extinguishing.Deflector can increase the ejection area of mixed liquor, improves fire-fighting efficiency, very convenient and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is internal structure schematic diagram of the present invention.
The specific embodiment
As one embodiment of the present invention, as depicted in figs. 1 and 2, a kind of self-protecting device for chassis of fire engine, comprise automatic holding device body 3, described automatic holding device body 3 is a three-way pipe, and described three-way pipe adopts 1Cr23Ni13 stainless steel to make, and three-way pipe inwall has rectangular channel, can increase the internal capacity of automatic holding device body 3, facilitate the abundant mixing of water, foam mixing liquid and air.In the present embodiment, as preferably, described automatic holding device body 3 is Y-shaped three-way pipe.Three-way pipe wherein one end port inner wall is provided with nozzle 5, and in the present embodiment, as preferably, described nozzle 5 is threadedly connected to wherein one end port inner wall of three-way pipe.On this port, be provided with nut 6, on described nozzle 5, have ladder hole, along the direction that enters three-way pipe, the aperture of ladder hole diminishes gradually.Three-way pipe is provided with filter mantle 4 near one end port of nozzle 5, and as preferably, described filter mantle 4 is connected with three-way pipe by screw.Three-way pipe is provided with deflector 1 away from one end port of nozzle 5, and described deflector 1 is obliquely installed, and the angle of itself and vertical plane is 30～60 degree.In the present embodiment, as preferably, deflector 1 is 30 degree with the angle of vertical plane.
In the present embodiment, as preferably, described deflector 1 is connected in three-way pipe away from one end port of nozzle 5 by adapter sleeve 2, adapter sleeve 2 is threaded with three-way pipe, deflector 1 is welded in adapter sleeve 2 away from one end of three-way pipe, and the face that adapter sleeve 2 is corresponding with deflector 1 is arranged to the inclined-plane corresponding with deflector 1.
Operation principle of the present invention is as follows; the present invention is connected with pipeline by nut 6; water and foam mixing liquid enter in three-way pipe through nozzle 5 under the effect of water pump; air enters in three-way pipe by filter mantle 4 under suction function; fully hybrid concurrency bubble is by deflector 1 ejection; the deflector 1 being obliquely installed makes the mixed liquor area of ejection larger, reaches the object of effective protection fire fighting truck.
The foregoing is only a kind of preferred embodiment of invention, in order to restriction invention, any modification of doing within all spirit in invention and principle, be equal to and replace and obvious mode of texturing etc., within all should being included in the protection domain of invention.
