Description

Technical Field

[0001] The invention relates to the technical field of security inspection, search and disposal of explosives and explosives, and in particular to a simulated explosion training device with exposed wires used by professional security inspectors and search and disposal of explosives personnel for practical training. Background Art

[0002] Crimes or terrorist activities carried out using explosive devices are very destructive to social stability and economic development. Under the current circumstances, it is increasingly urgent to prepare, respond, prevent and deal with explosion incidents in advance, which requires strengthening the training of security inspection, search and disposal personnel in the handling of explosive devices.

[0003] At present, there are many ways to detonate explosive devices, including pulling fire, collision and electric detonation. Compared with ignition, mechanical friction, impact and other detonation methods, electric detonation is more flexible and controllable. Electric detonation explosive devices can set different attack methods for different targets, so electric detonation explosive devices use electric detonation methods to pose a more realistic threat.

[0004] For electric detonation explosive devices, they can be divided into power supply part, operation part, detonation and explosive part in terms of structure and principle. The power supply part includes a battery pack that can provide power, and the power can also be provided by lighting AC. The operation part includes an electric control circuit with a predetermined structure; when certain conditions are met, the electric control circuit will output a predetermined trigger signal, and the trigger signal is sent to the detonation and explosive part. There are many types of electric control circuits, and suspects often modify them from small components commonly used in daily life. After receiving the trigger signal, the detonation and explosive part will cause the explosive to explode; detonation can be completed by electric detonators. If the explosive is black powder or the like, similar components such as electric ignition heads can also be used as the detonation part.

[0005] The trigger signal output by the above-mentioned operation part (i.e., the electronic control circuit) has various forms, which are generally divided into small signal output, large signal output, and switch signal output. Among them, if the output is a switch signal, when the conditions are met, such as receiving a remote control signal, or the delay time is reached, a switch closing signal is output; this signal can be used as a trigger signal for the detonation and explosive part, and then the detonation can be controlled. The method of using a switch closing signal to control the detonation is more common in actual explosion-related cases.

[0006] In order to enable professional security personnel and bomb search and disposal personnel to understand the working principles and performance of explosive devices and better deal with explosive devices, simulated explosion training devices are generally used to simulate explosions, and targeted training is provided to professional security personnel and bomb search and disposal personnel to deal with emergencies.

[0007] At present, the simulated explosion device generally includes an electric circuit formed by a power supply, an electric control circuit and an explosion simulator. The electric control circuit has two states. In one state, it maintains an open state, so that the electric circuit is disconnected, the explosion simulator loses power, and the explosion simulation effect is not performed; in the other state, it maintains a closed state (generating a trigger signal), so that the electric circuit is closed, the explosion simulator is powered on, and the explosion simulation is performed.

[0008] At present, there are many types of electronic control circuits, which can perform state transitions through timing, remote control, light control, magnetic control, etc. For example, when the time conditions are met, the circuit can be switched from an open state to a closed state, output a trigger signal, and power on the explosion simulator; the circuit can also be switched from an open state to a closed state according to a remote control signal, or from an open state to a closed state according to light intensity, and so on.

[0009] In real-life explosion-related cases, there are many explosive devices made of everyday electronic components. There are many types of explosive devices. How to provide corresponding types of simulated explosion training devices to improve training effects is a technical problem that technical personnel in this field need to solve. Summary of the invention

[0010] The invention provides a simulated explosion training device with exposed wires, so as to enable security inspection and bomb disposal personnel to understand the basic principle and structure of the explosive device and improve the training effect.

[0011] The explosion simulation training device with exposed wires provided by the present invention comprises a closed box body and a first power supply, a second power supply, a first electromagnetic relay, a second electromagnetic relay and an explosion simulator enclosed in the box body; the first electromagnetic relay has a first common end, a first normally open contact, a first normally closed contact and a first electromagnetic coil circuit that are arranged in a coordinated manner; the second electromagnetic relay has a second common end, a second normally open contact, a second normally closed contact and a second electromagnetic coil circuit that are arranged in a coordinated manner; the first common end is connected to the input end of the second electromagnetic coil circuit to form a second power-on input end, and is electrically connected to the output end of the second power supply through a second winding wire to form a complete electrical circuit; the second common end is connected to the input end of the first electromagnetic coil circuit to form a first power-on input end, and is electrically connected to the output end of the first power supply through a first winding wire to form another complete electrical circuit; in this way, "cross" control of the electromagnetic coil circuits and contact parts of the two electromagnetic relays is achieved, and the association of the two electrical circuits is achieved, and the power-on or power-off of the electromagnetic coil circuit on one electrical circuit will change the change of the contact state on the other electrical circuit. Among them, the loop ends of the two electromagnetic coil circuits are grounded; the power-on end of the explosion simulator is electrically connected to the first normally closed contact and the second normally closed contact, and its loop end is grounded; the first winding wire and the second winding wire are at least partially located outside the box body.

[0012] By using the simulated explosion training device with exposed wires, except for part or all of the first winding wire and the second winding wire, the other parts are sealed in the box body. During training, the winding wire (the first winding wire and / or the second winding wire) exposed outside the box body can be used to wind around the "hostage" or a specific object, and make it impossible to remove it. And keep the above two electrical circuits closed, the two electromagnetic coil circuits are powered on, the common ends of the two electromagnetic relays are in contact with the normally open contacts, the normally closed contacts are de-energized, and then the explosion simulator is in a de-energized state, and the explosion simulator does not "explode". If the simulated explosion training device is to be separated from the "hostage" or a specific object, simply cut off any winding wire located outside the box body, which will change the state of an electromagnetic relay, change the state of the contact of the other electrical circuit, and power on the normally closed contact, and then power on the explosion simulator, simulate the explosion, and fail to defuse the bomb. At this time, it is necessary to use other short-circuit wires to keep the power supply and the corresponding electromagnetic coil circuit closed, and then cut the winding wires, and then separate the simulated explosion training device from the "hostage" or a specific object to successfully defuse the bomb. In this way, the above method can make the trainees understand the principles of such explosive devices and train the bomb disposal methods, thereby achieving the purpose of training security inspection and bomb disposal personnel.

[0013] In a further technical solution, the loop end (which may be the negative pole) of the first power supply is grounded through a third winding wire, and the third winding wire is at least partially located outside the box body; or / and; the loop end of the second power supply is grounded through a fourth winding wire, and the fourth winding wire is at least partially located outside the box body. In this way, more winding wires can be used to bind the "hostage" or specific object to improve the simulation effect.

[0014] In a further technical solution, the power-on end of the explosion simulator is electrically connected to the first normally closed contact and the second normally closed contact through a safety switch; the safety switch is located in the box body; the box body is provided with a control window that matches the control part of the safety switch. When setting up the simulated explosion training device, the safety switch can be kept disconnected to avoid "explosion" caused by false triggering. When it is confirmed that the simulated explosion training device has been set up and is correct, the safety switch can be closed to put the simulated explosion training device in a state to be triggered. In this way, the state of the simulated explosion training device can be better switched, which is convenient for the management and storage of the simulated explosion training device and ensures the training effect.

[0015] In a further technical solution, a power switch is provided between the output end of the first power supply and the first winding wire; or / and; a power switch is provided between the output end of the second power supply and the second winding wire; the power switch is located in the box body; the box body is provided with a control window matching the control part of the power switch. In this way, the simulated explosion training device can be better controlled to change the output state of the power supply, which is convenient for the management and storage of the simulated explosion training device and ensures the training effect.

[0016] In a further optional technical solution, the first power supply and the second power supply are both electrically connected to a main power supply. This can simplify the circuit structure of the simulated explosion training device and reduce the cost of the simulated explosion training device.

[0017] In a further optional technical solution, a plurality of the first power supplies, a plurality of the second power supplies, a plurality of the first electromagnetic relays and a plurality of the second electromagnetic relays are included; one first power supply, one second power supply, one first electromagnetic relay and one second electromagnetic relay form a circuit module. In this way, multiple circuit modules can be formed, and more winding wires can be formed to improve the simulation effect.

[0018] In a further optional technical solution, an indication circuit is included in parallel with the first electromagnetic coil circuit, or / and an indication circuit is included in parallel with the second electromagnetic coil circuit; the box body is provided with a display window matching the indication circuit; or, an indication circuit is included in series with the first electromagnetic coil circuit, or / and an indication circuit is included in series with the second electromagnetic coil circuit; the box body is provided with a display window matching the indication circuit. Setting the indication circuit can more intuitively determine the state of the simulated explosion training device and improve the simulation training effect and efficiency.

[0019] In an optional technical solution, the explosion simulator includes an indicator light bulb, which can make the "explosion" more obvious and improve the training effect.

[0020] In the preferred technical solution, the simulated explosion training device with exposed wires also includes a plurality of short-circuit wires of predetermined lengths, and both ends of the short-circuit wires are provided with T-shaped pressing terminals, so that the winding wires can be short-circuited more conveniently, thereby improving the training effect.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the logical structure principle of a simulated explosion training device with exposed wires in an embodiment of the present invention; Figure 2 The figure is a schematic diagram of the circuit principle of a simulated explosion training device with exposed wires in an embodiment of the present invention.

[0032] In the embodiment, the simulated explosion training device with exposed wires includes a closed box body 100 and two power supplies 200, two electromagnetic relays 300 and an explosion simulator 400 enclosed in the box body 100. The power supplies 200, the electromagnetic relays 300 and the explosion simulator 400 are all enclosed in the box body 100, so that the trainee cannot modify the parts in the box body 100. The box body 100 can be packaged using existing packaging processes to ensure the connection reliability of the electronic components in the box body 100, while preventing others from arbitrarily changing the circuits and components in the box body 100.

[0033] For the convenience of description, in the specific description, the two power supplies 200 are described as the first power supply 210 and the second power supply 220 respectively; when not distinguished, they are collectively referred to as the power supply 200. The two electromagnetic relays 300 are described as the first electromagnetic relay 310 and the second electromagnetic relay 320 respectively; when not distinguished, they are collectively referred to as the power supply 300.

[0034] like Figure 2 As shown, the first electromagnetic relay 310 has a first common terminal COM1, a first normally open contact NO1, and a first normally closed contact NC1 ( Figure 2 right part) and the first electromagnetic coil circuit L1 ( Figure 2 Left side), when the first electromagnetic coil circuit L1 is powered on or off, the state of the first common terminal COM1 can be controlled. When powered on, the first common terminal COM1 is in contact with the first normally open contact NO1 and closed. When powered off, the first common terminal COM1 is in contact with the first normally closed contact NC1 and closed. Similarly, the second electromagnetic relay 320 has a second common terminal COM2, a second normally open contact NO2, and a second normally closed contact NC2 ( Figure 2 left side) and the second electromagnetic coil circuit L2 ( Figure 2 Right side); the principle is the same. When the second electromagnetic coil circuit L2 is powered on or off, the state of the second common terminal COM2 can be controlled. When powered on, the second common terminal COM2 contacts and closes with the second normally open contact NO2. When powered off, the second common terminal COM2 contacts and closes with the second normally closed contact NC2.

[0035] As shown in the figure, the first common terminal COM1 and the input terminal of the second electromagnetic coil circuit L2 are connected to form a second power-on input terminal 302, and the second power-on input terminal 302 is connected to the second power supply 220 ( Figure 2 The output end of the right power supply) is electrically connected through the second winding wire B, and the loop end (the other end) of the second electromagnetic coil circuit L2 is grounded to form a complete electrical circuit. The second common end COM2 is connected to the input end of the first electromagnetic coil circuit L1 to form a first power-on input end 301, and is connected to the first power supply 210 ( Figure 2The output end of the left power supply) is electrically connected through the first winding wire A, and the loop end (the other end) of the first electromagnetic coil circuit L1 is grounded to form another complete electrical circuit. In this way, the "cross" control of the electromagnetic coil circuits and contact parts of the two electromagnetic relays 300 can be achieved, and the association of the two electrical circuits can be achieved; that is, the electromagnetic coil circuit of the electromagnetic relay 300 in one electrical circuit is powered on or off, which will change the change of the contact state in the other electrical circuit.

[0036] The power-on end of the explosion simulator 400 is electrically connected to the first normally closed contact NC1 and the second normally closed contact NC2, and its loop end (the other end) is grounded. In this embodiment, the explosion simulator 400 may include a simulated electric detonator and an indicator bulb D3, and may also be provided with simulated explosives that are very close to real emulsion explosives in terms of appearance, texture, color, X-ray imaging, etc. When the simulated electric detonator and the indicator bulb part receive the detonation signal, the indicator bulb D3 lights up to indicate that the detonation has occurred. The reason for using the indicator bulb display is that the working current required by the electric ignition head in the electric detonator is about 300 mA or more, which can make the indicator bulb light up, so that the "explosion" can be more obvious and the training effect can be improved.

[0037] Among them, the simulated electric detonator can be composed of a processed electric ignition head and a detonator shell without explosives, so that trainees can master the appearance and structural characteristics of the actual electric detonator. Among them, the simulated explosive can be packaged in a PVC tube with an outer diameter of 32 mm. The simulated explosive filled inside can be very close to the real emulsion explosive in terms of appearance, texture, color, X-ray imaging, etc., so as to improve the training effect.

[0038] The first winding wire A and the first winding wire B are at least partially located outside the box body 100 . Of course, the first winding wire A and the first winding wire B may be completely located outside the box body 100 .

[0039] By using the simulated explosion training device with exposed wires, except for part or all of the first winding wire A and the second winding wire B, the other parts are sealed in the box body 100. In training, the winding wires (the first winding wire A and the second winding wire B) exposed outside the box body 100 can be used to wrap around the "hostage" or a specific object, and make it impossible to remove it. And keep the above two electrical circuits closed, the power supply 200 supplies power, the first electromagnetic coil circuit L1 and the second electromagnetic coil circuit L1 are powered on, the common ends of the two electromagnetic relays 300 are in contact with the normally open contacts, and the normally closed contacts are de-energized, so that the explosion simulator 400 is in a de-energized state, and the explosion simulator 400 does not "explode".

[0040] If the simulated explosion training device is to be separated from the "hostage" or a specific object, simply cut off any winding wire located outside the box body 100, such as the first winding wire A; Figure 2 The state of the electromagnetic relay 310 in the left electrical circuit changes the state of the contacts in the right electrical circuit, that is, the first common terminal COM1 is separated and disconnected from the first normally open contact NO1, and is closed with the first normally closed contact NC1; and then the first normally closed contact NC1 is powered on, so that the explosion simulator 400 is powered on, simulating an explosion, and the bomb disposal fails. Similarly, simply cutting the second winding wire B will also produce the same result of bomb disposal failure.

[0041] At this time, it is necessary to use other short-circuit wires to connect the two ends of the exposed part of the first winding wire A; at this time, even if the first winding wire A is cut, the electrical circuit of the second power supply 210 and the first electromagnetic coil circuit L1 can still be kept closed. In this way, the first winding wire A can be cut. In the same way, the second winding wire B can be cut, and then the first winding wire A and the second winding wire B can be processed accordingly to separate the simulated explosion training device and the "hostage" or specific object, or to perform subsequent processing; in this process, because the other short-circuit wires still keep the two electrical circuits closed, the explosion simulator 400 does not "explode" and the bomb can be successfully defuse.

[0042] Through the above method, trainees can understand the principles of such explosive devices and be trained in bomb disposal methods, thereby achieving the purpose of training security inspection and bomb disposal personnel.

[0043] According to the above description, in this embodiment, the loop end (negative pole) of the first power supply 210 can be grounded through the third winding wire C; the third winding wire C can be at least partially located outside the box body 100. The loop end of the second power supply 220 can also be grounded through the fourth winding wire D, and the fourth winding wire D can be at least partially located outside the box body 100. In this way, more winding wires can be used to bind the "hostage" or specific objects to improve the simulation effect.

[0044] In this embodiment, the box body 100 forms a square structure, and the first winding wire A, the second winding wire B, the third winding wire C, and the fourth winding wire D can be located at the four corners of the box body 100 to facilitate the use of the winding wires to tie the box body 100 simulating the explosive device to the "hostage" or a specific object.

[0045] like Figure 2As shown, a safety switch K3 may be provided between the power-on end of the explosion simulator 400 and the first normally closed contact NC1 and the first normally closed contact NC2, and the safety switch K3 is located in the box body 100; the box body 100 is provided with a control window that matches the control part of the safety switch K3. When setting up the simulated explosion training device, the safety switch K3 may be kept disconnected to avoid "explosion" caused by mis-triggering. When it is confirmed that the simulated explosion training device has been set up and is correct, the safety switch K3 may be closed to put the simulated explosion training device in a state to be triggered. In this way, the state of the simulated explosion training device can be better switched, which is convenient for the management and storage of the simulated explosion training device and ensures the training effect.

[0046] As shown in the figure, in this embodiment, a power switch K4 is arranged between the output end of the first power supply 210 and the first winding wire A. A power switch K5 is arranged between the output end of the second power supply 220 and the second winding wire B; the power switches K4 and K5 are located in the box body 100; the box body 100 is provided with a control window matching the control part of the power switches K4 and K5. In this way, the output state of the first power supply 210 and the second power supply 220 can be better controlled in the simulated explosion training device, which is convenient for the management and storage of the simulated explosion training device and ensures the training effect. Of course, in order to determine the power state more intuitively, an indicator light can also be arranged at the output end of the power supply 200, and the output state of the power supply 200 can be determined by the indicator light. The indicator light can be a light emitting diode or other light emitting indicating device. The indicator light can be connected to the output end of the corresponding power supply 200 in a serial or associated manner.

[0047] In an optional technical solution, the simulated explosion training device can be provided with a main power supply (which can be a main battery pack or an external power supply); and the first power supply 210 and the second power supply 220 are both electrically connected to the main power supply, and the first power supply 210 and the second power supply 220 are formed by corresponding power supply branches. In this way, the circuit structure of the simulated explosion training device can be simplified and the cost of the simulated explosion training device can be reduced.

[0048] According to the above description, it can be understood that the simulated explosion training device in the above embodiment can include a plurality of the first power supplies 210, a plurality of the second power supplies 220, a plurality of the first electromagnetic relays 310 and a plurality of the second electromagnetic relays 320. And one first power supply 210, one second power supply 220, one first electromagnetic relay 310 and one second electromagnetic relay 320 form a circuit module, thereby having more winding wires to improve the simulation effect.

[0049] like Figure 2As shown, in the above embodiment, the simulated explosion training device also includes an indication circuit connected in parallel with the first electromagnetic coil circuit L1, and the indication circuit is formed by a light-emitting diode D1 and an indication resistor R1 connected in series. When the first electromagnetic coil circuit L1 is powered on, the indication circuit is powered on, the light-emitting diode D1 emits light, and then the state of the first electromagnetic coil circuit L1 can be judged according to the indication circuit.

[0050] Similarly, the simulated explosion training device may also include an indication circuit connected in parallel with the second electromagnetic coil circuit L2; the box body 100 is provided with a display window matching the indication circuit, and the indication circuit may be formed by a light emitting diode D2 and an indication resistor R2 connected in series. It is understood that an indication circuit connected in series with the first electromagnetic coil circuit L1 or an indication circuit connected in series with the second electromagnetic coil circuit L2 may also be provided.

[0051] Corresponding to the indicating circuit, the box body 100 may be provided with a display window matching the indicating device, so as to more effectively observe the indicating state of the indicating circuit.

[0052] In order to facilitate simulated bomb disposal, the simulated explosion training device in the embodiment is also provided with a plurality of short-circuit wires of predetermined lengths, and T-shaped push-on terminals are provided at both ends of the short-circuit wires. By appropriately squeezing the winding wires through the T-shaped push-on terminals, electrical connection can be conveniently achieved, so that the winding wires can be short-circuited more conveniently, thereby improving the training effect. The plurality of short-circuit wires can be of different colors for easy distinction. The short-circuit wires can have a relatively long length, such as 1 meter, so as to conveniently short-circuit the winding wires.

[0053] Finally, it should be noted that the above is only a preferred embodiment of the present invention, which is only used to illustrate the technical solution of the present invention, and is not used to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
