Background technology
Destroying waste and old ammunition timely and effectively is an important process of army.Destroy waste and old ammunition and generally adopt the method for decomposing dismounting, but special for some structures, fuse combines very tight and difficult decomposition dismounting with bullet the ammunition of scrapping needs demolition.A kind of demolition method wherein is, adopt laser ignition to ignite detonator, by detonator detonation energy is transferred to the cumulative initiator, the metal jet penetration that utilizes the cumulative initiator to form is gone in the ammunition housing to be destroyed, and then the internal charge of ignition ammunition, realize ammunition disposal.But, take the direct mode of igniting of energy of low-cost low-power laser output often to be difficult to guarantee to ignite reliably detonator.
The utility model content
The purpose of this utility model is to provide a kind of laser ignition power density intensifier.It can strengthen laser output power density, is used to solve the integrity problem that low-power laser is ignited booster.
For achieving the above object, the utility model adopts following technical scheme:
A kind of laser ignition power density intensifier, it comprises:
One cylindrical shell, this cylindrical shell has a front end-plate, an end plate and sidewall, and described end plate is fixedlyed connected with the output of laser generator and is had the through hole of exporting laser, and described front end-plate is provided with connecting hole;
One metal strengthens head, is installed in the described connecting hole, and this metal strengthens head and has the detonator installing hole along axis, is used to install detonator; And
One focus lamp is installed in the described cylindrical shell near described lead to the hole site by means of a focus lamp support, and this focus lamp focal length is slightly larger than this focus lamp and converges focus to the distance of described metal enhancing cephalic par and laser and be positioned at described detonator installing hole.
Preferably, described detonator installing hole is a shoulder hole, and the big footpath bore dia of this shoulder hole equals the detonator external diameter, and should be positioned at the outside that described metal strengthens head in hole, big footpath, and the diameter in its hole, thin footpath is slightly less than the diameter in hole, described big footpath.The length in hole, described thin footpath can be 0.8-1.5mm.
Described cylindrical shell is a rectangle housing, and its sidewall comprises left supported plate, right supported plate, base plate and cover plate, and described focus lamp support is installed on the described base plate.Described cylindrical shell also can be the cylindrical shell of other shapes, as cylinder or polygon prism.
Compared with prior art, laser ignition power density intensifier of the present utility model adopts laser convergence to strengthen technology, promptly laser is converged in the detonator installing hole of metal enhancing head by focus lamp, detonator is wherein ignited, can realize low-power laser ignition detonator, the probability of laser blasting detonator can be brought up to 100%, thereby improve laser blasting detonator reliability.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, 2, the utility model is made up of cylindrical shell, focus lamp, focus lamp support and metal enhancing four part; Cylindrical shell is mainly formed a lighttight rectangle housing of relative closure by gland 2, front end-plate 5, end plate 1, left supported plate 3, right supported plate 7 and base plate 6, wherein end plate 1 is fixed on the laser output slab of laser generator, have through hole on the end plate 1, through-bore axis and the dead in line of output laser.Focus lamp support 9 is fixed on close end plate 1 one sides on the inner barrel base plate 6, and focus lamp 8 is fixed on the focus lamp support 9, focus lamp 8 axis and laser output dead in line.It is a metal cylinder that metal strengthens 4, is installed in the connecting hole that front end-plate 5 is provided with, and passes and is fixed on the front end-plate 5 from the connecting hole of barrel front end plate 5.Metal strengthens 4 and has a cylindrical stepped through hole along axis, and this shoulder hole is used for installing location detonator 10, this shoulder hole axis also with the output laser dead in line of laser generator.Metal strengthens an end that 4 shoulder hole diameters are bigger towards the cylindrical shell outside, and its diameter is identical with detonator external diameter size, and detonator 10 therefrom passes.The hole, thin footpath of shoulder hole is positioned at metal and strengthens an inboard of 4, and its length is about the 0.8-1.5 millimeter, and diameter is slightly less than detonator 10 external diameters.Metal strengthens 4 focal lengths that are slightly less than focus lamp 8 towards inner barrel one side end face apart from focus lamp 8 centre distances, makes laser converge the middle position that laser focal spot that the focus place produces drops on detonator 10.
The course of work of the present utility model is such: before the operation, select pulse frequency, pulsewidth and the wavelength of output laser according to the kind of detonator 10.When output laser runs into focus lamp 8, when line focus effect to metal strengthened detonator 10 oral areas in 4 shoulder hole, focal spot unit are power density increased tens of times approximately.Air moment that laser action will make metal strengthen 4 inside is heated, metal enhancing 4 inner tubal wall deform and are in pressured state, because metal strengthens the firm wall effect of 4 a shoulder hole inside, air dielectric is subjected to the tube wall effect and forms the moment adiabatic compression in the tube chamber at this moment, thereby making a series of compressional waves stacks that air dielectric produces in whole adiabatic compression process form the shock wave that pressure discontinuities raise, this shock wave is to detonator 10 internal delivery.Meet or exceed the critical explosion velocity of detonator 10 when the shock velocity that detonates, the shock wave that detonates obtains enough prolongations to the detonator continuous action time, the energy that the combustion chemistry reaction of the inner trace explosive of the detonator that is caused is emitted makes the shock front that detonates keep necessary pressure, will guarantee the stable DDT process detonation of the inner generation of detonator.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
