Detailed description of the invention
The hole-bottom blast protective device that the utility model embodiment provides, solve the detonator mount pad introduced in background technology and easily rotate, in the detonator mount pad caused, detonator position is not fixed, the problem that explosive effect is not good.
Technical scheme in the utility model embodiment is understood better in order to make those skilled in the art person, and enable the above-mentioned purpose of the utility model embodiment, feature and advantage become apparent more, below in conjunction with accompanying drawing, the technical scheme in the utility model embodiment is described in further detail.
Figure 1 show the overall structure of a kind of hole-bottom blast protective device that the utility model embodiment provides.The hole-bottom blast protective device that the utility model provides, comprises cartridge case 1 and detonator mount pad 2, and described detonator mount pad 2 is fixed on one end of described cartridge case 1; On described cartridge case 1 inwall, the position corresponding with described detonator mount pad 2 is provided with projection 11; Described detonator mount pad 2 is provided with groove 21, and described groove 21 is connected with described projection 11 circumference realized described detonator mount pad 2 and locates.
By the position corresponding with detonator mount pad 2 on cartridge case 1 inwall, projection 11 is set, at detonator mount pad 2, groove 21 is set, be connected with projection 11 circumference realized detonator mount pad 2 by groove 21 to locate, thus the detonator mount pad 2 preventing priming device rotates the detonator position be fixed on detonator mount pad 2 caused changes, the problem that the explosive effect caused is not good, enhances Detonation Initiation Effect.
As shown in Figure 2 A, as a kind of preferred embodiment, the one end fixing described detonator mount pad 2 in described cartridge case 1 is provided with detonator opening 12.
In actual job, the detonator stretched out from detonator opening 12 often easily and big gun hole wall rub, cause quick-fried poor effect, even cannot detonate, in order to address this problem, as shown in Figure 2 A, detonator tube seat 13 can be provided with at described cartridge case 1 outer wall, detonator tube seat 13 diameter is greater than detonator diameter, and described detonator tube seat 13 is communicated with described detonator opening 12.By arranging the detonator tube seat 13 be connected with detonator opening 12; detonator is placed in detonator tube seat 13, can, when the actual use of hole-bottom blast protective device, avoids detonator and big gun hole wall to rub; serve the protective effect to detonator, thus ensure that and lead quick-fried effect.
Conveniently detonator stretches out to cartridge case 1 from detonator mount pad 2, as shown in Figure 3A, position that can be corresponding with described cartridge case 1 detonator opening 12 on described detonator mount pad 2 is arranged wears mouth 22, facilitates detonator to extend to cartridge case 1 from the detonator mount pad 2 of fixing detonator.
In the practical application of hole-bottom blast protective device, detonator mount pad 3 often only has a detonator fixing hole, can only fix single detonator, causes Detonation Initiation Effect not good.In order to optimize technique scheme further, in above described holes base initiation protective device, described detonator mount pad 2 can be provided with multiple detonator fixing hole 23.As shown in Figure 3 B, detonator fixing hole 23 is two, can place two detonators.For only placing the hole-bottom blast protective device of a detonator at present, the success rate of detonating can be increased.
As shown in Figure 4; as a kind of preferred embodiment, described hole-bottom blast protective device, also comprises protective cover 3; described protective cover 3 covers one end of the described detonator mount pad 2 of installation of described cartridge case 1, and described protective cover 3 and described detonator mount pad 2 form seal protection chamber.Protective cover 3 can the detonator of protection setting on detonator fixing hole 23, and can also play dust-proof effect, prevents impurity from entering in seal protection chamber, cause blasting cap detonation effect influenced.
In the operating process of the hole-bottom blast protective device described in above-described embodiment; because protective cover 3 protecting against shock lacks in ability; in the process that hole-bottom blast protective device pushes at the bottom of hole, big gun hole; protective cover 3 is often easily impacted; cause the detonator in protective cover 3 impaired; increase the danger of hole-bottom blast, therefore, described protective cover 3 outer surface can be set to sphere.Because the outer surface of protective cover 3 is sphere; increase the lifting surface area of protective cover; sphere is when being subject to impacting simultaneously; can the impulsive force be subject to be distributed on whole sphere; greatly can increase the protecting against shock ability of hole-bottom blast protective device like this; protect detonator and the explosive of protective device inside of detonating, thus improve the security of operation of detonating.
In the above-described embodiments, described protective cover 3 can be connected by screw thread, hinge or buckle with the connected mode of described cartridge case 1.The utility model embodiment does not limit the connected mode of protective cover 3 and cartridge case 1, and those skilled in the art can select the connected mode of protective cover and cartridge case according to actual conditions.
In order to the Making programme of easy hole-bottom blast device, prevent hole-bottom blast protective device coupling too high simultaneously, easily loosen, each parts of described hole-bottom blast protective device are formed in one structure.To be formed in one structure by each parts of providing holes base initiation protective device, can to reduce the possibility that loosening appears in hole-bottom blast protective device in operation, each parts structure that is formed in one also can save material simultaneously, reduces production cost.In actual fabrication process; each parts can adopt high density polyethylene (HDPE) 8008 to be fed to injecting machine material tube through storing, injection, pressurize, cooling aftershaping by the proportioning mixing of the orange master batch of every 25 kilograms/150g; wherein; the composition of orange master batch is the composite material of toner, superfine material and adjuvant; injection temperature controls between 180 degree of-220 degree, to obtain high performance hole-bottom blast protective device.
In sum; just the hole-bottom blast protective device on cartridge case is withheld simply compared to the detonator mount pad of the fixing detonator mentioned in background technology; the hole-bottom blast protective device that the utility model provides is arranged projection 11 by the position corresponding with detonator mount pad 2 at cartridge case 1 sidewall and is corresponded to the position of cartridge case 1 sidewall projection 11 at detonator mount pad 2 sidewall and arranges groove 21, when cartridge case 1 fastens with detonator mount pad 2.Make the projection 11 of cartridge case 1 be connected with the groove 21 of detonator mount pad 2 circumference realized described detonator mount pad 2 to locate, detonator mount pad left-right rotation can be prevented, thus prevent the detonator position in detonator mount pad to change, the problem that explosive effect is not good may be caused, considerably increase the security of detonating.
Each embodiment in this description all adopts the mode of going forward one by one to describe, between each embodiment identical similar part mutually see, what each embodiment stressed is the difference with other embodiment.
Above-described the utility model embodiment, does not form the restriction to the utility model protection domain.Any do within spirit of the present utility model and principle amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
