Description
Technical field
Detection of the present invention for metal film flying after blasting cap detonation in engineering explosion field.
Background technique
It is well known that blasting cap detonation only need tens it is delicate can complete, generated after explosion largely with several kms per second
The metal fragment to disperse at high speed has very big since its is small in size, quantity is more, speed is fast, sharp edges, disperses distance far
Destructive power and lethality, commonsense method is difficult to observe the process of its explosion.Current state-of-the-art High Speed Photography is also only capable of
Capture luminous effect process when blasting cap detonation.Common can only test individual metal using the pulse electrical measuring method of signal on-off
The speed of film flying.And instrument and equipment needed for the above method is at high price, does not have for most of researchs, technical staff
These conditions.Currently, there is no effective inspection for the process of dispersing of the metal fragment of a large amount of high speed generated after blasting cap detonation
Survey means.
Summary of the invention
In order to which the technology for solving not detecting a large amount of high-velocity wire separation of fragments processes generated after blasting cap detonation at present is difficult
Topic, the present invention propose a kind of new method, can effectively capture a large amount of metal film flyings of blasting cap detonation generation, and safely may be used
It leans on, is simple and easy, is low in cost, can be grasped by numerous technical staff.
The technical scheme is that due to the direction of metal film flying after blasting cap detonation it is main there are two, one is detonator
Head sockets for collecting energy direction, referred to as axially, another with it is axially vertical, referred to as radially；Metal film flying on blank sheet of paper when passing through
Perforation trace can be left, different size, shape, speed, the fragment perforation size, the shape, notch that leave on blank sheet of paper in direction
Situations such as sharp degree and distribution, is different.Therefore, it uses blank sheet of paper as target sheet, captures thunder using target sheet axial in front of detonator
A large amount of metal film flyings that pipe explosion time axially generates, a large amount of gold radially generated when capturing blasting cap detonation using side radial direction target sheet
Belong to film flying.Specific steps are as follows: one, select a hard platform, it is successively horizontal from bottom to top to place aluminium sheet, plastic foam plate, axial target
Paper；Two, using a blank sheet of paper be rolled into diameter be 28cm, high 40cm paper tube as radial direction target sheet, on 25cm eminence marking pen edge
The rubber slab of one 3mm thickness is rolled into the cylinder of an interior diameter 28cm, high 40cm, radial target sheet is bonded by one horizontal circle of target sheet mural painting
It is fixed on rubber tube inner wall；Three, rubber drum is centrally placed on axial target sheet, with marking pen in axial target sheet on the inside of cylinder bottom
One circle of upper picture, target sheet placement are completed；Four, detonator wire to be detected is pierced by from explosion-proof iron upper box part central aperture, adjusts thunder
Tube head is located at target sheet 25cm eminence, fixed detonator；Five, explosion-proof iron case is placed on aluminium sheet between two parties, detonator is answered at this time
In radial target sheet center 25cm eminence；Six, it is covered on explosion-proof iron case and is properly protected with one layer of cotton, started video recording and take pictures, detonate
Detonator；Seven, explosion-proof tank is removed, target sheet is recycled and is numbered, in detail record field condition, and keeps live associated materials；Eight, right
The energy-gathering jetting that is stayed on target sheet after blasting cap detonation, the number of holes of metal film flying, size, shape, distribution situation are analyzed.
The invention has the advantages that the metal fragment of the high-speed flight generated after being able to detect that blasting cap detonation is big
It is situations such as small, shape, distribution, safe and reliable, simple and easy, low in cost, it is research blasting cap detonation metal fragmentation rule
Effective means.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is detection target sheet structural schematic diagram.
Fig. 2 is explosion-proof iron case schematic diagram.
1. axial target sheet in figure, 2. plastic foam plates, 3. aluminium sheets, 4. radial target sheets, 5. rubber tubes, 6. apertures.
Specific embodiment
A hard platform is selected first, it is successively horizontal from bottom to top to place aluminium sheet (3), plastic foam plate (2), axial target sheet
(1)；Then a blank sheet of paper is rolled into the radial target sheet (4) that diameter is 28cm, high 40cm, in 25cm eminence marking pen along target sheet
One horizontal circle of mural painting, then the rubber slab of 3mm thickness is rolled into the rubber tube (5) of an interior diameter 28cm, high 40cm, by radial target sheet
(4) fitting is fixed on rubber tube (5) inner wall, and then rubber tube (5) is placed between two parties on axial target sheet (1)；With marking pen edge
Rubber tube (5) bottom inside one circle of picture on axial target sheet (1)；By detonator wire to be detected from explosion-proof iron upper box part central aperture
(6) it is pierced by, adjustment detonator head is located at target sheet 25cm eminence, fixed detonator；Explosion-proof iron case is placed in aluminium sheet (3) between two parties
On, detonator should be in paper tube center 25cm eminence at this time；It is covered on explosion-proof iron case and is properly protected with one layer of cotton, started video recording and clap
According to detonating capsule；Explosion-proof tank is finally removed, target sheet is recycled and is numbered, in detail record field condition, keeps live related material
Material；The number of holes of the energy-gathering jetting, metal film flying that are stayed on target sheet after blasting cap detonation, size, shape, distribution situation are carried out
Analysis.
According to the method described above, respectively the single-shot detonator to single-shot detonator, equipped with head protector, bind detonator single-shot thunder
Pipe, equipped with head protector and bind detonator single-shot detonator generate high-velocity wire film flying carry out testing inspection, according to score
The situations of change such as the number of holes, distribution, size, the shape that metal film flying under different operating conditions stays on target sheet are analysed, are obtained
The high-velocity wire film flying generated after blasting cap detonation with external condition changing rule, and propose accordingly protection detonator explosion cumulative
The effective measures of jet stream and metal film flying.
