Description

Technical Field

[0001] This utility model relates to a teaching simulation device, and more particularly to a teaching simulated explosion device. Background Technology

[0002] The teaching-use simulated explosion device stems from the need for in-depth understanding of explosion phenomena and improvement of response skills in industrial production, laboratory safety, and emergency response training; the teaching-use simulated explosion device plays an important role in enhancing learners' safety awareness, operational skills, and emergency response capabilities.

[0003] In emergency situations such as natural disasters, laboratory safety accidents, and industrial safety accidents, it is crucial to take rapid and accurate emergency response measures. Therefore, it is necessary to simulate explosion scenes to help trainees conduct emergency drills in realistic environments, including evacuation, rescue, and firefighting operations, thereby improving their emergency response capabilities and teamwork skills.

[0004] Existing teaching-grade simulated explosion devices mostly use sound and light media for demonstrations. However, these devices generate significant recoil during explosions, which can easily cause mechanical damage to the devices, affecting their lifespan. Furthermore, mechanically damaged simulated explosion devices can easily injure instructors and trainees during demonstrations. Therefore, existing teaching-grade simulated explosion devices cannot guarantee the safety of instructors and trainees. On the other hand, teaching-grade simulated explosion devices with low recoil simulate explosions that differ significantly from real explosions, thus reducing the effectiveness of training in operational skills and emergency response capabilities.

One end of the roller is connected to a micro motor through a connecting shaft. The micro motor is set on the bottom surface of the placement plate. The micro motor is electrically connected to a controller and the battery.

[0008] The lower part of the inner wall of the four sides of the housing is provided with shock-absorbing plates extending towards the center. The shock-absorbing plates are located below the placement plate and are arranged parallel to the placement plate. An elastic component is provided between the placement plate and the shock-absorbing plates. The bottom of the housing is provided with the controller, the wireless signal controller and the battery.

[0009] Furthermore, projection slots are provided at the bottom of the four outer walls of the housing. A rotating shaft is rotatably arranged between the two side walls of the projection slot, and the rotating shaft is located at the top of the projection slot. One end of the rotating shaft is connected to the side wall of the projection slot through a rotary motor. The rotary motor is electrically connected to the controller and the battery respectively. A mounting plate is engaged at the center of the rotating shaft. The mounting plate has a U-shaped structure. Both ends of the mounting plate are connected to the outer peripheral surface of the rotating shaft. A projector is arranged on the side of the mounting plate opposite to the rotating shaft. The projector is electrically connected to the controller through a control connection line passing through the mounting plate and the rotating shaft. The projector is also electrically connected to the battery.

[0010] Furthermore, a transparent protective plate is engaged at the beginning of the projection slot.

[0011] Furthermore, a charging port is provided at the bottom of the housing, and the charging port is electrically connected to the battery.

[0012] Furthermore, an external antenna is provided at one end of the top surface of the housing (the external antenna includes multiple sleeves arranged sequentially from the outside to the inside, as described in the specification), and the external antenna is electrically connected to the wireless signal controller.

[0013] Furthermore, a fixing plate is provided at the bottom end of each of the two side walls of the housing, and at least one fixing plate is provided on each side wall. A fixing hole is provided at the center of the fixing plate, and the two fixing plates are arranged symmetrically to each other.

[0014] Furthermore, the interior of the four side walls of the shell and the interior of the placement plate surrounding the acoustic and optical media chamber are all fitted with shock-resistant layers.

[0015] Furthermore, the top ends of the plurality of elastic components are fixedly connected to the bottom surface of the placement plate, and the bottom ends of the plurality of elastic components are respectively fixedly connected to the top surface of the corresponding shock-absorbing layer plate.

[0016] Furthermore, the elastic component is a helical spring.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. This utility model, employing a combination of a shell and a placement plate, solves the problems of short service life and compromised safety for instructors and trainees during explosion demonstrations in existing teaching-grade simulated explosion devices. During an explosion demonstration, the controller is first instructed via buttons and the display screen to rotate a micro-motor in the forward direction. This micro-motor drives the rollers to rotate, causing the trigger plate to move downwards and compressing the rebound assembly. The audio-visual media device is then inserted into the audio-visual media chamber. The teaching-grade simulated explosion device is then placed at the designated demonstration location. The danger zone is calculated based on the device's specifications. After instructors and trainees have exited the danger zone, the instructor sends a signal to the wireless signal controller within the teaching-grade simulated explosion device, instructing the controller to issue an explosion demonstration command. The controller then sends a command to the micro-motor, causing it to rapidly rotate in the reverse direction. At this time, the rebound component quickly returns to its initial state. The trigger plate moves upward under the thrust of the rebound component and comes into contact with the bottom surface of the sound and light medium device. Even though the conductive sheet comes into contact with the trigger device at the bottom of the sound and light medium device, since the conductive sheet is connected to the battery, the conductive sheet can form a closed circuit with the trigger device at the bottom of the sound and light medium device, controlling the electrical components inside the sound and light medium device to start, simulating the sound, light, and smoke scene during an explosion, completing the explosion demonstration, and improving the safety of this utility model. During the simulated explosion, the sound and light medium device will generate a downward recoil force. Therefore, the placement plate will move downward under the action of the recoil force of the sound and light medium device. At this time, the elastic component is compressed and stores elastic potential energy. After the recoil force disappears, the elastic potential energy is released and the device returns to its initial state. This can effectively prevent the recoil force generated by the sound and light medium device during the explosion from causing mechanical damage to the teaching simulated explosion device and extend the service life of this utility model.

[0019] 2. This invention ensures the safety of instructors and trainees during explosives training by using projection slots located at the bottom of the four outer walls of the casing and a projector within these slots for marking. During use, the instructor inputs the radius of the danger zone into the controller via buttons and a display screen, based on the danger zone of the audio-visual medium. The controller then controls the rotating motor to rotate forward or backward, thereby rotating the shaft to adjust the projector's emission angle and the safety distance range. The projector then marks the danger zone on the placement plane using emitted laser rays. After the instructor and trainees leave the danger zone, the instructor sends a signal to the wireless signal controller within the simulated explosive device, issuing an explosion demonstration command to complete the simulated explosion demonstration. The projector makes the danger zone more intuitive during blasting demonstrations, allowing trainees to clearly identify the danger zone and ensure they are outside of it. This prevents injuries caused by incorrect distance estimations by trainees, greatly improving the safety and practicality of this invention.

[0020] 3. This utility model protects the projector inside the projection slot by setting a transparent protective plate at the beginning of the projection slot, preventing damage to the projector during handling or moving of this utility model, or dust generated during a simulated explosion from entering the projection slot and causing damage to the projector. This extends the service life of the projector, reduces the maintenance cost of this utility model, and improves its practicality.

[0021] 4. This utility model, by providing a charging port at the bottom of the casing, enables charging without removing the battery, reducing the number of steps required for charging and improving its convenience and practicality.

[0022] 5. This utility model, by using an antenna installed in the casing, ensures that even in a large danger zone, the wireless signal controller can accurately receive wireless signals by extending the external antenna. This ensures that after instructors and trainees have left the danger zone, the wireless signal controller can still receive signals sent by instructors from a distance, thereby enabling instructors to issue explosion demonstration commands to the controller from a distance. This completes the simulated explosion demonstration and prevents the inability to cancel the activation of the audio-visual media device when the evacuation time is set incorrectly or when the explosion demonstration needs to be canceled due to special circumstances. This further improves the convenience and safety of this utility model, while also expanding its scope of application and enhancing its practicality.

[0023] 6. By setting fixing plates at the bottom of the two side walls of the shell, the present invention can be placed at the designated demonstration location during use. The teaching simulated explosion device is firmly fixed on the placement plane by fixing columns, which prevents the present invention from shifting during explosion demonstration and causing injury to instructors and students. This improves the safety and practicality of the present invention.

[0024] 7. This utility model absorbs the vibration waves generated by the acoustic and optical media device during the explosion demonstration by setting anti-vibration layers inside the shell and the placement plate, thereby extending the service life of the shell and the placement plate, reducing the maintenance cost of this utility model, and improving its practicality.

[0025] 8. By fixing the top ends of multiple elastic components to the placement plate and the bottom ends of multiple elastic components to the shock-absorbing layer plate, the present invention enables multiple elastic components to be securely engaged between the placement plate and the shock-absorbing layer plate, thereby increasing the force of the elastic components on the recoil force, extending the service life of the present invention, and improving the practicality of the present invention.

The two pull ropes 12 are located inside the rebound assembly 11 and are set against the inner wall of the rebound assembly 11. When the pull rope 12 is in a taut state, it can limit the rebound assembly 11, so that the position of the rebound assembly 11 can always be maintained between the bottom surface of the trigger plate 8 and the end of the trigger groove 7). The pull rope 12 passes through the end of the trigger groove 7 and surrounds the outer periphery of the roller 13.

The shock-resistant layers 30 are made of flexible materials that can absorb shock wave energy, such as silicone.

[0037] like Figure 2As shown, shock-absorbing plates 16 are provided on the lower part of the inner walls of the four sides of the housing 1, extending towards the center.

The side of the housing is provided with heat dissipation holes 31 corresponding to the positions of the controller 15, the wireless signal controller 18 and the battery 10.

[0038] like Figure 1 , Figure 4As shown, projection slots 19 are provided at the bottom of the four outer walls of the housing 1. A transparent protective plate 25 is engaged at the beginning of the projection slot 19. A rotating shaft 23 is rotatably arranged between the two side walls of the projection slot 19, and the rotating shaft 23 is located at the upper or middle part of the projection slot 19, preferably at the upper part of the projection slot 19, so that the projector 22 can project a farther distance. One end of the rotating shaft 23 is connected to the side wall of the projection slot 19 through a rotary motor 20. The rotary motor 20 is a high-torque forward and reverse micro speed-regulating motor of brand: Meigaolian, model: 36GM-3530.

[0039] like Figure 1 As shown, an external antenna 27 is provided at one end of the top surface of the housing 1. The external antenna 27 is a retractable linear antenna, such as a ZAVE 44-30 telescopic antenna. The external antenna 27 is electrically connected to the wireless signal controller 18.

[0040] like Figure 1 As shown, the bottom ends of the two side walls of the shell 1 are provided with fixing plates 28 extending outwards. At least one fixing plate 28 is provided on each side wall (two fixing plates 28 are shown in the figure). A fixing hole 29 is provided at the center of the fixing plate 28. The fixing plates 28 on the two sides are symmetrically arranged. A fixing post is provided through multiple fixing holes 29. The teaching simulated explosion device can be firmly fixed on the placement plane by pressing the fixing post through multiple fixing holes 29. The fixing post can be a ground nail or other fixing component.

[0041] The specific working principle is as follows:

[0042] In use, first, press the button to give a command to the controller, causing the controller to control the micro motor to rotate forward. The micro motor drives the roller to rotate, causing the pull rope to wrap around the outer surface of the roller. At this time, the trigger plate moves downward under the pull of the pull rope. Because the two pull ropes are located inside the rebound assembly and are set against the inner wall of the rebound assembly, when the pull ropes are in a taut state, they can limit the rebound assembly, keeping the position of the rebound assembly between the bottom surface of the trigger plate and the end of the trigger groove, compressing the rebound assembly and storing elastic potential energy. Based on the usage characteristics of the sound and light media device, select a simulated explosion device with a matching sound and light media chamber (or replace it with one equipped with...). The audio-visual media device is placed in the audio-visual media housing (with a matching placement plate). Common audio-visual media devices include those fixed by screws or those fixed by snap-fit. The teaching simulated explosion device is then placed at the designated demonstration location and securely fixed to the placement surface using fixing posts. The danger zone is then calculated based on the marked danger zone of the audio-visual media device or its specifications. The radius of the danger zone is input into the controller via buttons and a display screen. The controller then sends a command to the rotating motor, controlling its forward or reverse rotation, thereby driving the shaft. The projector can be rotated forward or backward to adjust its emission angle, thereby regulating the safe distance range. Since the projector is perpendicular to the placement plane, the side of the casing, the placement plane, and the emitted beam form a triangle. Therefore, the required projection distance can be calculated using relevant formulas. A danger zone is then marked on the placement plane using the linear laser beam emitted by the projector. If the danger zone is large, the external antenna needs to be extended to ensure accurate reception of the wireless signal by the wireless signal controller. After the instructors and trainees retreat to the safe zone (i.e., exit the marked danger zone), the instructors will transmit the signal via wireless signal. The wireless signal controller installed inside the transmitter and the teaching simulated explosion device works together to issue commands to the controller. The controller sends commands to the micro motor, which rotates rapidly in the opposite direction. At this time, the rebound component quickly returns to its initial state by releasing elastic potential energy. The trigger plate moves upward under the thrust of the rebound component and comes into contact with the bottom surface of the sound and light media device. That is, the conductive sheet comes into contact with the trigger device at the bottom of the sound and light media device. Since the conductive sheet is connected to the battery, it can form a closed circuit with the trigger device at the bottom of the sound and light media device, controlling the electrical components inside the sound and light media device to start, simulating the sound, light, and smoke of an explosion, and completing the explosion demonstration.

[0043] During a simulated explosion, the acoustic-optical media device generates a downward recoil force. Consequently, the placement plate moves downwards under this force. The elastic component is compressed, storing elastic potential energy, which is released after the recoil dissipates, restoring the device to its initial state. This effectively prevents mechanical damage to the teaching-use simulated explosion device caused by the recoil force generated during the explosion. Furthermore, the airflow generated by the placement plate's vertical movement dissipates heat from the wireless signal controller, controller, and battery located at the bottom of the housing (airflow rapidly circulates through ventilation holes on the side of the housing, facilitating air exchange between the inside and outside of the housing). This ensures the teaching-use simulated explosion device can perform multiple explosion demonstrations in a short period. The vibration waves generated by the acoustic-optical media device during the explosion demonstration are absorbed by the shock-absorbing layers inside the housing and placement plate, reducing their impact and extending their lifespan.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
