Description
Technical field
The utility model belongs to the industrial explosive material technical field, particularly a kind of multi-functional detonation tool.
Background technology
At present mine be used to the to detonate initiating equipment of desensitized explosive of no cap-sensitivity is a detonation tool, and the product that seismic prospecting is used is explosive-source explosive post.Its structure of detonation tool, powder charge, performance indications etc. are relatively more ripe, and each producer's differentiation of product is little.Its powder charge of explosive-source explosive post have emulsification, colloid, glue, ammonium ladder, ladder too, ladder a lot of explosive kinds such as aluminium too.Charge process also has casting to adorn, press-fit, smash dress, spiral shell dress etc.Because powder charge kind and technology difference, properties of product also vary.The product water-resistance that has product high and low temperature resistance not all right, that have product compressive property not all right, that have is not all right, does not satisfy requirement when deep-well and seafari.And because the energy difference of detonating that different occasion needs, detonation tool is also having plurality of specifications qualitatively, and these have all increased the complexity of product.
Summary of the invention
At the deficiency that prior art exists, the utility model provides a kind of multi-functional detonation tool.
This detonation tool comprises housing, main ingredient chamber, vestibule and medicine core chamber; This detonation tool is cylindrical, and housing, main ingredient chamber and medicine core chamber are circular, is followed successively by housing, main ingredient chamber and medicine core chamber from outside to inside, its middle shell, main ingredient chamber and coaxial connection of medicine core chamber; Vestibule is distributed between main ingredient chamber and the medicine core chamber;
Described housing rear and front end is distributed with screw thread, and housing outer surface adopts rough design, and a housing outer surface middle part circumference mostly is provided with groove longitudinally, not only can improve casing rigidity but also have and well hold sense, the convenient connection.
Described vestibule is at least two, and can be beneficial to connect lead, primacord and detonator for through hole, half hole and reducing through hole.
Described detonation tool can be in housing rear and front end assembling tapered cap and protective cap, suit fixed wings outside housing.
Described vestibule inwall and end face coated with water blocking material.Can be waterproof and dampproof, and can prevent detonation tool in use explosive component dissolve in polluted underground water in the water, play the effect of environmental protection.
The using method of this detonation tool: the detonate needs single-shot of energy of the visual basis of multi-functional detonation tool uses or connects and uses, detonation tool housing front end screw thread can be screwed on tapered cap is arranged, tapered cap is a plastic cylinder that front end is taper, tail end has internal thread, can be connected with housing by screw thread during use.Protective cap can be connected with housing by screw thread, prevents that the barbarous operation of prescribe medicine process from causing security incident.Protective cap is a columnar plastic barrel, and is that its front end face is shut and thicker, and certain intensity is arranged.Its front portion has external screw thread, can be connected with housing.Also wing can be installed and fixed on the housing, big gun hole central authorities can be well detonation tool be fixed on during coupling charging at needs.Fixed wings is a plastic circle ring, has four " pawls " that stretch to the foreign side of retreading above the annulus, or title " wing ".Internal radius and detonation tool housing external diameter tight fit can be enclosed within on the housing.One reducing is arranged on the housing, just in time fixed wings can be blocked.
Dress in the blast hole chamber during this detonation tool since boring to keep away rough powder charge meeting not smooth, its front end is equipped with tapered cap can make things convenient for powder charge.Powder charge does not also need to use metallic rod to disclose in the hole when smooth, because the detonation tool powder charge is the explosive of high energy high sensitivity, detonator also is equipped with in inside during use, and metallic rod is disclosed on explosive or detonator and caused danger easily.The protective cap that front end is had thicker end socket is screwed in detonation tool housing tail end, and metallic rod is just disclosed less than on the explosive, like this can be very safe.Also some the time bore diameter bigger, greater than the detonation tool diameter, detonation tool just can not be placed in the middle in the hole, can the erratic hole wall of swinging to.Fixed wings is enclosed within on the detonation tool housing, and its four " pawls " that stretch to oblique foreign side are supported on the hole wall and can will be fixed on the center of boring.The tapered cap of front end, the protective cap of afterbody and fixed wings all are the annexes of detonation tool, can select to install or do not install according to the needs that the user uses.
High sensitivity priming core also is equipped with in detonation tool inside, and safe and reliable the detonating of prodigiosin that guarantee to detonate also can use the low energy initiating equipment as 6
#Detonator, 3.6g/m primacord etc. detonate.
Advantage of the present utility model: this detonation tool detonation continuity is very good, and (5 kilograms) detonation is complete after 10 connections.Degree of packing is not less than 1.6g/cm
3, explosion velocity is not less than 7000m/s, water repelling property under the 0.7mpa hydraulic pressure immersion 10 days after 8
#Blasting cap initiation detonation is complete.Gap distance is greater than 60mm.Present its density of most explosive-source explosive post is at 1.0～1.2g/cm
3Between, explosion velocity is less than 6000m/s.Its every index and this detonation tool all have certain gap.
This detonation tool is particularly suitable for deep hole, waits and to using under the high condition of index requests such as explosion velocity, power, sensitivity, brisance under water.
