Compared with prior art, the utility model adopts glass fibre reinforced plastics to make motor body, has significantly reduced the fabricating cost of housing from the 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.Under the situation that satisfies the forest extinguishing usage requirement, to have made out and had in light weightly, cost is low, and the motor that the fire-fighting bomb for forest that performance is good is used helps the universal use of local fire brigade.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the 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, blanking cover before the 8-tapped hole, 9-, blanking cover behind the 10-, 11-damping spring, 12-positioning ring, 13-igniting polar.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment.The engine structure schematic representation that a kind of fire-fighting bomb for forest of the present utility model is used comprises the housing made from glass fibre reinforced plastics 1 as shown in Figure 1, is provided with the solid-state gunpowder 2 that is pressed into tubulose in the housing 1, the center hole of tubulose forms the firing chamber of motor naturally.The tail end of solid-state gunpowder 2 is provided with the electric igniter 3 that is made of the insensitiveness circuit, the jet pipe 4 of a compression moulding of the useful carbon cloth phenolic aldehyde of electric igniter 3 peripheral hardwares.The glass fibre reinforced plastics of making housing 1 is to coat epoxy resin with glass fiber to be wrapped on the mould the dry back demoulding and to make, and 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 on the contraction-like cone of housing outer wall, should guarantee the relative position of the circumferential tapped hole 8 of stabilization wing and front end (seeing below the explanation in double thread hole) during stickup.The inwall of housing 1 tail end is open horn mouth, and the horn mouth place is provided with jet pipe 4, and jet pipe 4 also is to be bonded in the open horn mouth of housing tail end inwall, and is bonding reliable for guaranteeing, should carry out air tightness test to guarantee its tightness after bonding finishing.The inwall two ends of jet pipe 4 also are bell-mouthed, the horn mouth of front end is that one section horn mouth for larynx lining, rear end of converging portion, middle straight is a diffuser, select for use the carbon cloth phenolic aldehyde as the jet pipe material during making, once suppress integral body 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 guarantees to connect, in the housing 1 of positioning boss 6 front ends, be provided with stiffening ring 7, along the radial tapped hole 8 that connects with housing that is evenly equipped with of stiffening ring 7 circumference, be used for being connected with Fire-extinguishing shell reliably.Blanking cover 9 and back blanking cover 10 were provided with damping spring 11 between the positioning boss 6 in preceding blanking cover 9 and the housing 1 before solid-state gunpowder 2 two ends were respectively equipped with, and were provided with positioning ring 12 between solid-state gunpowder 2 and the housing 1.By preceding blanking cover 9, back 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 a bolt, so that with the fastening outside lead that inserts of nut.Insensitiveness circuit in igniting polar 13 and the electric igniter 3 is connected.The insensitiveness circuit directly adopts insensitiveness circuit traditional in the prior art, this insensitiveness circuit has more blunt reaction with respect to sensitive circuit to IGNITION CONTROL voltage, be that the control voltage of the insensitiveness circuit condition that do not meet the requirements of just not can turning circuit, this relative sensitive circuit is safety relatively.Igniter originally is to adopt the mechanical isolation insurance is set between motor electric squib and engine ignition medicine or main charge; Because the utility model has adopted technique scheme, the utility model can not only guarantee to satisfy the Safety performance requirement of igniter, improves the working stability performance of motor, and can also reduce the cost of production of grenade greatly.
