Description

Technical Field

[0001] This utility model relates to the technical field of impact plate detonation devices, specifically an integrated impact plate detonation device. Background Technology

[0002] A device that detonates explosives by instantaneously applying a large current pulse to a metal bridge foil, causing it to vaporize and generate high-temperature, high-pressure plasma, which drives a flying disc to impact the explosive at high speed, is called an impact disc detonator. Impact disc detonators are widely used in military equipment both domestically and internationally. Impact disc detonators require a capacitor discharge unit to provide initiation energy, thus forming an impact disc initiation system. Currently, impact disc initiation systems generally consist of discrete high-voltage capacitors, high-voltage switches, high-voltage connectors, impact disc detonators, and connecting cables. For reliable initiation, the high-voltage capacitor must have a sufficiently large capacity, the discharge switch must have a sufficiently fast closing speed, and the discharge circuit must be as short as possible to minimize energy loss in the line.

[0003] Most existing impact plate detonation devices are fixed to the corresponding detonator positions with bolts, which makes disassembly of the detonation device very troublesome. At the same time, the structure of existing impact plate detonation devices is relatively complex, which increases the corresponding manufacturing cost. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0022] Please see Figures 1 to 6 This utility model provides a technical solution: an integrated impact plate detonation device, including a body 1, a connecting through hole inside the body 1, a rotating shaft 2 rotatably connected inside the connecting through hole, a limit lever 3 provided at the lower end of the rotating shaft 2, a receiving slot 4 provided at the bottom of the body 1, the limit lever 3 slidably connected inside the receiving slot 4, an adjusting cap 5 slidably connected at the upper end of the rotating shaft 2, a first spring 6 provided on the inner wall of the adjusting cap 5, the end of the first spring 6 away from the adjusting cap 5 being located at the upper end of the rotating shaft 2, an installation groove inside the body 1, a high-voltage capacitor 7 provided inside the installation groove, an explosion bridge foil 8 provided on the inner wall of the installation groove, the explosion bridge foil 8 and the high-voltage capacitor 7 being electrically connected to each other, a flyer layer 9 provided on the lower surface of the explosion bridge foil 8, and an acceleration chamber 10 at the lower end of the flyer layer 9.

[0023] Specifically, by rotating the control cap, the rotating shaft 2 is driven to rotate, causing the limiting lever 3 to retract into the receiving slot 4, thereby allowing the detonating device body 1 to be quickly removed from the corresponding detonator. The bridge foil 8, flyer layer 9, and acceleration chamber 10 are sequentially detonated on the high-voltage capacitor 7 base, followed by loading and encapsulation with a shell, forming an integrated impact detonator that highly integrates the capacitor discharge unit (CDU) and the impact detonator. Employing planar high-voltage switch and detonating foil integration technology, the system eliminates the need for printed circuit boards, silicone rubber wires, and connectors (components essential in typical impact detonator systems), achieving an integrated impact detonator and significantly reducing system size. Compared to traditional discharge circuits using wires and connectors, this greatly reduces energy loss during discharge and avoids the impact of connector contact resistance on discharge performance. Integrated encapsulation improves reliability and versatility. The small discharge circuit area allows for the use of a metal shell, minimizing electromagnetic interference to other circuits during high-voltage discharge.

[0024] Please see Figure 2-3 The lower surface of the adjusting cap 5 is provided with a limiting post 12, and the upper surface of the body 1 is provided with a storage groove. The inside of the storage groove is provided with a limiting hole 13. The position of the limiting hole 13 is adapted to the position of the limiting post 12. The adjusting cap 5 is slidably connected inside the storage groove.

[0025] Specifically, by setting the limiting post 12 and the limiting hole 13, when the limiting post 12 is inside the limiting hole 13, the rotating shaft 2 is limited, thereby preventing the limiting rod 3 from rotating freely and ensuring the stability of the detonation device when it is installed inside the corresponding detonator.

[0026] Please refer to 3. The inner top wall of the adjusting cap 5 is provided with a positioning slide rod 14, which is slidably connected inside the rotating shaft 2.

[0027] Specifically, by setting the positioning slide bar 14, the rotating shaft 2 can rotate smoothly with the adjusting cap 5, while preventing the adjusting cap 5 from detaching from the rotating shaft 2.

[0028] Please see Figure 3 A limit bearing 15 is provided on the outer surface of the rotating shaft 2, and the limit bearing 15 is located inside the body 1.

[0029] Specifically, the stability of the rotation of the rotating shaft 2 is ensured by the setting of the limit bearing 15.

[0030] Please see Figure 1 There are two rotating shafts 2 and two adjusting caps 5, which are symmetrical to each other.

[0031] Specifically, the stability of the detonation device body 1 when installed inside the corresponding detonator is ensured by setting two sets of rotating shafts 2 and adjusting caps 5.

[0032] Please see Figure 1 The upper surface of the body 1 is provided with a mounting through hole, and an electrode post 16 is provided inside the mounting through hole. The electrode post 16 and the high voltage capacitor 7 are electrically connected to each other.

[0033] Specifically, by setting the electrode post 16, an external current can be connected to the high-voltage capacitor 7 for effective detonation.

[0034] In use, by pulling the control cap, the first spring 6 is stretched, causing the limiting post 12 to disengage from the limiting hole 13. Then, rotating the control cap causes the rotating shaft 2 to rotate, causing the limiting lever 3 to retract into the receiving slot 4, allowing the detonating device body 1 to be installed into the corresponding detonator. Next, the control cap is reversed, exposing the limiting lever 3, which then engages with the corresponding detonator. At this point, the limiting post 12 and the limiting hole 13 are aligned. Releasing the control cap allows the limiting post 12 to engage with the limiting hole 13 under the elastic force of the first spring 6. When the limiting post 12 is inside the limiting hole 13, it limits the rotation shaft 2, thereby preventing the limiting lever 3 from rotating freely. This ensures the stability of the detonating device when installed inside the corresponding detonator, completing the fixed installation. For disassembly, pull the control cap again to stretch the first spring 6, causing the limiting post 12 to disengage from the limiting hole 13. Then, rotate the control cap, driving the rotation shaft 2 to rotate, causing the limiting lever 3 to retract into the receiving slot 4. This allows the detonating device body 1 to be quickly removed from the corresponding detonator. (The last sentence appears to be incomplete and possibly refers to a separate process: "In high-voltage electricity...") The container 7 consists of an explosive bridge foil 8, a flyer layer 9, and an acceleration chamber 10, all sequentially mounted on the base. The explosive is then loaded and encapsulated in a shell, forming an integrated impact detonator that highly integrates the capacitor discharge unit (CDU) and the impact detonator. Employing planar high-voltage switch and explosive foil integration technology, the system eliminates the need for printed circuit boards, silicone rubber wires, and connectors (components essential in typical impact detonator systems), significantly reducing system size. Compared to traditional discharge circuits using wires and connectors, this greatly reduces energy loss during discharge and avoids the impact of connector contact resistance on discharge performance. Integrated encapsulation enhances reliability and versatility. The small discharge circuit area allows for a metal shell, minimizing electromagnetic interference to other circuits during high-voltage discharge. This facilitates quick removal of the detonator from the detonator and simplifies the mechanism, reducing production costs.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
