In the motor that above-mentioned fire-fighting bomb for forest is used, described in make housing glass fibre reinforced plastics be with glass fiber coat epoxy resin be wrapped in dry on mould after the demoulding make.
In the motor that aforesaid fire-fighting bomb for forest is used, the outer wall of described housing tail end is contraction-like cone, and contraction-like cone is provided with at least two stabilization wings, and the inwall of housing tail end is open horn mouth, and horn mouth place is provided with jet pipe.
In the motor that aforesaid fire-fighting bomb for forest is used, the front inner wall of described housing is provided with positioning boss, in the housing of positioning boss front end, is provided with stiffening ring, along the radial tapped hole connecting with housing that is evenly equipped with of stiffening ring circumference.
In the motor that aforesaid fire-fighting bomb for forest is used, described solid-state gunpowder two ends are respectively equipped with front blanking cover and rear blanking cover, between the positioning boss in front blanking cover and housing, are provided with damping spring.
In the motor that aforesaid fire-fighting bomb for forest is used, between described solid-state gunpowder and housing, be provided with positioning ring.
In the motor that aforesaid fire-fighting bomb for forest is used, described electric igniter is provided with igniting polar, and igniting polar is connected with the insensitiveness circuit in electric igniter.
Compared with prior art, the present invention adopts glass fibre reinforced plastics to make motor body, has significantly reduced the fabricating cost of housing from material, has alleviated the weight of motor.Structure to motor is optimized, and has reduced difficulty of processing, has improved manufacturing efficiency, has also reduced processing cost.In the situation that meeting forest extinguishing usage requirement, to make out and had lightweightly, cost is low, and the motor that the fire-fighting bomb for forest that performance is good is used is conducive to the universal use of local fire brigade.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Being labeled as in accompanying drawing: 1-housing, the solid-state gunpowder of 2-, 3-electric igniter, 4-jet pipe, 5-stabilization wing, 6-positioning boss, 7-stiffening ring, 8-tapped hole, blanking cover before 9-, blanking cover after 10-, 11-damping spring, 12-positioning ring, 13-igniting polar.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Embodiment.The engine structure schematic diagram that a kind of fire-fighting bomb for forest of the present invention is used as shown in Figure 1, comprises the housing 1 made from glass fibre reinforced plastics, is provided with the firing chamber of the center hole self-assembling formation motor of the solid-state gunpowder 2, the tubulose that are pressed into tubulose in housing 1.The tail end of solid-state gunpowder 2 is provided with the electric igniter 3 being made up of insensitiveness circuit, once compressing jet pipe 4 of the useful carbon cloth phenolic aldehyde of electric igniter 3 peripheral hardware.The glass fibre reinforced plastics of making housing 1 be with glass fiber coat epoxy resin be wrapped on mould dry after the demoulding make, the cylindrical of mould is corresponding with the inner wall shape of housing 1.The outer wall of housing 1 tail end is contraction-like cone, contraction-like cone is provided with at least two stabilization wings 5, stabilization wing 5 is to be bonded in the contraction-like cone of housing outer wall, should ensure the relative position of the circumferential tapped hole 8 of stabilization wing and front end (seeing below the explanation in double thread hole) when stickup.The inwall of housing 1 tail end is open horn mouth, and horn mouth place is provided with jet pipe 4, and jet pipe 4 is to be also bonded in the open horn mouth of housing tail end inwall, bonding reliable for guaranteeing, should carry out air tightness test to ensure its tightness after bonding completing.The inwall two ends of jet pipe 4 are also bell-mouthed, the horn mouth of front end is that converging portion, middle straight the one section horn mouth for larynx lining, rear end is diffuser, when making, select carbon cloth phenolic aldehyde as jet pipe material, once suppress entirety and shape, can improve the manufacturing efficiency of jet pipe.Also can guarantee certain burning erosion amount and usability.The front inner wall of housing 1 is provided with positioning boss 6, the housing 1 of positioning boss 6 front ends is connected with Fire-extinguishing shell, for the reliability that ensures to connect, in the housing 1 of positioning boss 6 front ends, be provided with stiffening ring 7, along the radial tapped hole 8 connecting with housing that is evenly equipped with of stiffening ring 7 circumference, for being connected with Fire-extinguishing shell reliably.Solid-state gunpowder 2 two ends are respectively equipped with front blanking cover 9 and rear blanking cover 10, between the positioning boss 6 in front blanking cover 9 and housing 1, are provided with damping spring 11, between solid-state gunpowder 2 and housing 1, are provided with positioning ring 12.By front blanking cover 9, rear blanking cover 10 and positioning ring 12, solid-state gunpowder 2 is located.Damping spring 11 can play buffer function, can prevent the bad solid-state gunpowder 2 of shake in carrying or transportation process.Electric igniter 3 is provided with igniting polar 13, and igniting polar 13 can be bolt, so that the wire accessing with fastening nuts outside.Igniting polar 13 is connected with the insensitiveness circuit in electric igniter 3.Insensitiveness circuit directly adopts insensitiveness circuit traditional in prior art, this insensitiveness circuit has more blunt reaction with respect to sensitive circuit to IGNITION CONTROL voltage, be the control voltage of insensitiveness circuit do not meet the requirements of condition just not can turning circuit, this relative sensitive circuit is safer.Igniter is originally to adopt mechanical isolation insurance is set between motor electric squib and engine ignition medicine or main charge; Because the present invention has adopted technique scheme, the present invention can not only guarantee to meet the Safety performance requirement of igniter, improves the working stability performance of motor, and can also greatly reduce the cost of production of grenade.
