Description

Technical Field

[0001] This utility model relates to a training device for simulating bomb disposal, belonging to the field of bomb disposal training technology. Background Technology

[0002] Bomb disposal personnel bear the heavy responsibility of protecting lives and property. Faced with dangerous explosives, they must remain calm and decisive. Through sophisticated bomb disposal simulation training, their practical skills and emergency response levels can be continuously improved. In simulated environments, they learn how to identify different types of explosives, master complex dismantling techniques, and conduct drills for various emergencies. This high-intensity training not only hones their professional skills but also cultivates their psychological resilience in emergency situations, enabling them to make rapid and accurate judgments and actions when facing real dangers. For example, Chinese invention patent CN112785889A discloses an explosive simulation trainer and a bomb disposal drill system and method based on flexible composite explosion-proof technology. This explosive simulation trainer can simulate common explosion effects such as vibration, noise, flash, smoke, and fragmentation, and can be triggered using multiple methods to simulate the triggering methods of different existing explosives. The proposed solution lacks a device for igniting smoke pellets. This would require pre-igniting the smoke pellets before placing them into the smoke-generating agent box and then loading them into the main explosive control box. This process could easily burn operators, posing a safety hazard. Furthermore, the smoke-generating agent box can only hold a limited number of smoke pellets, necessitating frequent refills, which is cumbersome and impacts training efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a training device for simulating bomb disposal. This invention can control the ignition of smoke-making rods, thus ensuring high safety; moreover, multiple smoke-making rods can be installed at once, reducing the number of installations and making it convenient to use.

[0004] The technical solution of this utility model is as follows: A training device for simulating bomb disposal includes a housing with a microcontroller inside; a cover is connected to the top of the housing, and a display screen and an operating shell are respectively provided on the cover, with an explosive wire inside the operating shell; the display screen and the explosive wire are connected to the microcontroller via wiring; multiple smoke-generating mechanisms are symmetrically arranged on both sides of the housing, each smoke-generating mechanism including a mounting base on the side of the housing with a placement groove; a smoke-loading tube is connected to the inner side of the mounting base and extends into the housing; the inside of the smoke-loading tube communicates with the placement groove; multiple trigger pins are provided at the inner end of the smoke-loading tube, and the trigger pins are connected to the microcontroller via wiring; a smoke-generating rod is placed inside the smoke-loading tube, and multiple trigger holes are provided at the bottom of the smoke-generating rod, with the trigger holes corresponding to the trigger pins; a protective cover is detachably connected to the outer end of the mounting base; a smoke outlet is provided on the inner side of the smoke-loading tube; multiple overflow holes are provided on the bottom surface of the operating shell, and the overflow holes are connected to the smoke outlet via pipes.

[0005] The aforementioned training device for simulated bomb disposal has an arc groove on the top of the housing, and a data interface is provided inside the arc groove. The data interface is connected to a microcontroller via a circuit.

[0006] The aforementioned training device for simulated bomb disposal has multiple flashlights on its shell cover; buzzers are symmetrically arranged on the shell cover; and the flashlights and buzzers are connected to a microcontroller via circuitry.

[0009] The aforementioned training device for simulated bomb disposal has multiple guide bars on the side of the placement slot, which extend into the smoke-filling tube; and multiple guide grooves on the side of the smoke-making rod, which cooperate with the guide bars.

[0010] The aforementioned training device for simulated bomb disposal has a first threaded portion on the mounting base and a second threaded portion on the inner side of the protective cover, which engages with the first threaded portion.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In this utility model, trainees perform bomb disposal operations. The display screen on the casing shows bomb disposal information. Trainees remove the explosive leads inside the casing to complete the bomb disposal. During the bomb disposal process, the capacitor on the microcontroller sends a high-voltage current to the trigger pin. Because the trigger pin is inserted into the trigger hole of the smoke-making rod, the smoke-making rod gradually heats up and burns under the action of the high-voltage current, generating smoke. The smoke flows out from the smoke outlet and overflows from the overflow hole, filling the casing with smoke, interfering with the trainees and enhancing their response capabilities. After use, the smoke-making rod can be replaced by removing the protective cover, allowing this utility model to be reused multiple times and reducing training costs.

[0013] 2. In this utility model, a buzzer emits a loud bang and a flashlight emits intermittent light to interfere with the trainees' auditory and visual senses, thereby further enhancing their responsiveness.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0022] Example: A training device for simulating bomb disposal, configured as follows Figure 1-5 As shown, it includes a housing 1, such as Figure 2 As shown, a microcontroller 2 is installed inside the housing 1. The microcontroller 2 integrates a processor and electronic devices such as capacitors. The microcontroller 2 is an existing product and can be obtained commercially. In this embodiment, the microcontroller 2 of model STC89C52 is used. A cover 3 is connected to the top of the housing 1. The cover 3 is equipped with a display screen 4 and an operating shell 5. The operating shell 5 is a semi-closed plastic structure with an opening at the top, with an opening size of 15cm × 10cm and a height of 5cm. 3-5 explosive wires 28 of different colors are fixed inside. The display screen 4 and the explosive wires 28 are connected to the microcontroller 2 via wiring. The display screen 4 is used to display bomb disposal information, such as "Remove the red wire, complete within 120 seconds" and the result (success / failure). Trainees need to remove specific explosive wires 28 to achieve bomb disposal. Six smoke-making mechanisms 6 are symmetrically arranged on both sides of the housing 1, three on each side. Figure 3As shown, the smoke-making mechanism 6 includes a mounting base 7 located on the side of the housing 1, with a placement groove 8 having a diameter of 3cm and a depth of 6cm on the mounting base 7; a smoke-loading tube 9 is connected to the inner side of the mounting base 7, extending into the housing 1 with a length of 10cm and an inner diameter consistent with the placement groove 8; the interior of the smoke-loading tube 9 communicates with the placement groove 8; the inner end of the smoke-loading tube 9 is provided with six 1mm diameter copper trigger pins 10, which are connected to a microcontroller 2 via circuitry, allowing a 10-15kV current to be passed through during capacitor discharge; a smoke-making rod 11 is placed inside the smoke-loading tube 9, the smoke-making rod 11 being cylindrical with a diameter of 2.8cm and a length of 5cm, and made of a mixture of potassium nitrate and sawdust, pressed together. Figure 5 As shown, the bottom of the cigarette-making rod 11 has six trigger holes 12 that match the trigger needle 10. The holes are 1mm in diameter and 2cm deep, and are filled with potassium nitrate ignition medium. The side of the placement groove 8 has three guide strips 24 arranged in a triangle, extending into the cigarette-loading tube 9. The side of the cigarette-making rod 11 has three guide grooves 25 that cooperate with the guide strips 24. When the cigarette-making rod 11 is placed into the placement groove 8, the guide grooves 25 on the side of the cigarette-making rod 11 are aligned with the guide strips 24 to ensure that the trigger needle 10 is aligned with the trigger holes 12 after the cigarette-making rod 11 is placed into the cigarette-loading tube 9. Figure 5 As shown, a protective cover 13 is detachably connected to the outer end of the mounting base 7, and the protective cover 13 has a smoke outlet 14; the inner side of the smoke-loading pipe 9 has a smoke outlet 14; the bottom surface of the operating shell 5 has multiple overflow holes 29, which are connected to the smoke outlet 14 via pipes. These pipes are made of silicone and are fixed to the smoke outlet 14 and overflow holes 29 at both ends by clips to ensure no smoke leakage. Smoke can flow along the path of "burning smoke rod 11 → smoke-loading pipe 9 → smoke outlet 14 → overflow hole 29 → inside the operating shell 5," accumulating inside the semi-enclosed operating shell 5, obscuring the explosive wire 28, and creating visual interference. The mounting base 7 has a first threaded portion 26; the inner side of the protective cover 13 has a second threaded portion 27, which is screwed onto the first threaded portion 26 to connect the protective cover 13 and the mounting base 7. Figure 2 As shown, the top of the housing 1 is provided with an arc groove 15, and a data interface 16 is provided within the arc groove 15. The data interface 16 is connected to the microcontroller 2 via a circuit. Preset bomb disposal scenario parameters (including wire removal rules, smoke triggering time, and timing duration) are imported into the microcontroller 2 through the data interface 16, ensuring that each bomb disposal training session is different. Figure 1As shown, the housing cover 3 is equipped with multiple flashlights 17, which are high-brightness LEDs with a wavelength of 620-660nm and a brightness of 500lm. A buzzer 18, with a decibel level of 80-120dB, is symmetrically arranged on the housing cover 3. The flashlights 17 and buzzers 18 are connected to the microcontroller 2 via circuitry. By emitting a popping sound from the buzzer 18 and intermittently illuminating the flashlights 17, a system of "1Hz intermittent flash + 80-100dB popping sound" can be achieved after training begins. In case of bomb disposal failure, the system switches to "3Hz flash + 120dB sound," providing auditory and visual interference to the trainees and further enhancing their responsiveness. An expansion block 19 is provided on the side of the housing 1, and multiple operation buttons 20 are mounted on the expansion block 19. The operation buttons 20 are connected to the microcontroller 2 via circuitry. One button is a "start / stop button" that controls the overall start and stop of the device; the other is a "smoke emergency stop button" that can manually cut off the trigger signal of the smoke-generating mechanism 6. The upper end of the housing 1 is provided with a mounting plate 21, on which mounting slots 22 are symmetrically arranged, and a timer 23 is installed within each slot. The timer 23 can be set so that the trainee can perform bomb disposal operations at the designated time.

[0023] Training process:

[0024] 1. Scenario preset: Import bomb disposal scenario parameters to microcontroller 2 via USB data interface 16: "Remove the red wire, time 120 seconds, trigger smoke 30 seconds after training starts, sound and light interference intensity level 1 1Hz flash + 80dB sound, intensity level 2 3Hz flash + 120dB sound in case of failure".

[0025] 2. Device startup: The trainee presses the "start / stop" button on expansion block 19, the timer 23 starts counting down, the display screen 4 displays the task: "Remove the red wire, 120 seconds remaining", the flashlight 17 and the buzzer 18 activate level 1 interference.

[0026] 3. Smoke triggering: After 10 seconds, the microcontroller 2 controls the high-voltage capacitor to discharge, and the trigger needle 10 is supplied with current, which breaks through the ignition medium in the trigger hole 12 of the smoke-making rod 11 and ignites the smoke-making rod 11; the smoke passes through the smoke-filling tube 9, the smoke outlet 14 and the overflow hole 29 in sequence and enters the operating shell 5, where it accumulates and obscures the color of the wire.

[0027] 4. Bomb Disposal Operation: Under the conditions of "smoke-shrouded operating shell + audible and visual interference", the trainee reaches into the operating shell 5 to remove the wires; if the red wire is removed, the signal detection module of the microcontroller 2 recognizes the correctness, immediately stops the smoke triggering and audible and visual interference, the timer 23 stops, and the display screen 4 displays "Bomb Disposal Successful, Time Taken 45 Seconds"; if other colored wires are removed or the timeout is exceeded, the microcontroller 2 controls the audible and visual interference to switch to level 2, the display screen 4 displays "Bomb Disposal Failed", and at the same time triggers all smoke-generating mechanisms 6 to continuously emit smoke for 10 seconds.

[0028] 5. Device Reset: After training, unscrew the protective cover 13, remove the used smoke-making rod 11 along the guide bar 24, replace it with a new smoke-making rod, press the "Start / Stop" button to reset, and you can start the next training session.
