Description

Technical Field

[0001] The present application relates to the technical field of training or testing systems, and in particular to a door and window breakthrough simulation system and an application method thereof, which are used for conducting door and window breakthrough training and testing the damaging effects of projectiles on doors and windows. Background Art

[0002] Public security and military personnel often need to forcibly enter buildings (using tools or weapons), for example, to rescue people trapped in a burning building or hostages held by terrorists. Saving a few seconds in these situations can mean the difference between life and death, making proficiency in door-breaking skills crucial. To this end, some organizations have developed door-breaking training systems. For example, Breaching Technologies has developed a variety of mechanically punched door-breaking training doors for door-breaking training. These doors simulate the various forces encountered in real-world scenarios, providing operators with a realistic sense of door-breaking (see patent documents US2009208914A1 and US2014141394A1).

[0003] However, existing door-breaking training systems are often complex to build and install, resulting in high costs. Furthermore, these systems are often designed only for fixed-type security doors, resulting in limited training scenarios and modes. They can only be used for door-breaking training, but are unable to test the damage effects of projectiles on doors and windows, making them difficult to meet practical needs. Summary of the Invention

[0004] The purpose of this application is to propose a door and window breakthrough simulation system and its application method to solve the problems of the existing system's complex composition and installation operation, high cost, and single application scenario.

[0005] In a first aspect of the present application, a door and window breakthrough simulation system is disclosed, comprising a base, two side frames of identical structure, and a plurality of door and window simulations, wherein the two side frames are relatively movably assembled on the base to form a variable clamping space between the base and the two side frames for selectively clamping any one of the plurality of door and window simulations; wherein:

[0006] The base is a rectangular frame with an axisymmetric structure. The middle positions of the two short sides of the rectangular frame are connected by a T-shaped guide groove, and the two long sides of the rectangular frame are respectively provided with bolt guide grooves;

[0007] The side frame includes an L-shaped bracket, and the horizontal portion and the vertical portion of the bracket are respectively provided with continuous mounting grooves on the inner corner sides of the bracket. When the two side frames are assembled on the base with the inner corner sides facing each other, the two vertical mounting grooves and the two horizontal mounting grooves jointly define the clamping space for clamping the door and window simulation object;

[0008] The bottom surface of the horizontal part of the bracket extends downward to form a T-shaped guide rail that is adapted to the T-shaped guide rail groove of the base. The T-shaped guide rail and the T-shaped guide rail groove form a sliding mechanism so that the side frame can be relatively movably assembled on the base; the two side surfaces of the horizontal part of the bracket extend laterally to form a horizontal support arm, and the end of the horizontal support arm is provided with a bolt mounting hole. The head of the T-shaped bolt is installed in the bolt guide rail groove of the base, and the bolt passes through the bolt mounting hole at the end of the horizontal support arm and is connected with the nut.

[0009] In some other examples, the door and window simulations include at least real iron security doors, metal window guards, wooden doors, and simulations thereof.

[0010] In some other examples, the door and window simulation object includes a data acquisition unit, and the door and window breakthrough simulation system further includes a data analysis device.

[0011] In some other examples, a second mounting groove having a predetermined length is formed at the bottom of the mounting groove of the vertical portion of the bracket in the vertical direction, and the two second mounting grooves of the two side frames jointly define a second clamping space for clamping the door and window simulation.

[0012] In certain other examples, the horizontal arm forms a bending structure at the end near the horizontal part of the bracket, and the bending structure includes a horizontal section connected to the side of the horizontal part of the bracket and a vertical section for connecting the horizontal section to the horizontal arm part. The length of the horizontal section meets the following conditions: when the T-shaped guide rail is assembled in the T-shaped guide rail groove, the inner side surface of the vertical section and the outer side surface of the T-shaped guide rail groove partially overlap in the vertical direction and fit with an appropriate gap in the horizontal direction.

[0013] In some other examples, the T-shaped guide rail is located directly below the bottom surface of the horizontal portion of the bracket, and the front end surface of the T-shaped guide rail along the side frame assembly direction is arranged rearward relative to the front end surface of the horizontal portion of the bracket.

[0014] In some other examples, the rear end of the T-shaped guide rail is connected to the rear side of the upper end of the vertical part of the bracket through a rear rib plate, and the two ends of the horizontal support arm are connected to the two sides of the upper end of the vertical part of the bracket through a side rib plate respectively.

[0015] In some other examples, the mounting slots of the horizontal and vertical portions of the side frame are formed by continuous wings on both sides.

[0016] In some other examples, the base and side frames are welded from aluminum alloy or stainless steel angle steel, or are made of wood structure.

[0017] In a second aspect, the present application discloses a method for conducting door and window breaching training or testing the damage effects of projectiles on doors and windows using the door and window breaching simulation system, comprising:

[0018] (1) Place the base on the ground;

[0019] (2) Slide the convex T-shaped guide rail of the side frame along the concave T-shaped guide rail into the base;

[0020] (3) Install the bolts and nuts and keep the nuts loose so that the T-bolts connected to the ends of the side frame horizontal arms can slide freely in the bolt guide grooves;

[0021] (4) Install the door and window simulation in the mounting slot of one of the side frames;

[0022] (5) moving the other side frame or moving both side frames simultaneously to clamp the iron door and window simulation in the clamping space defined by both side frames;

[0023] (6) Tighten the nuts to lock the side frame and base;

[0024] (7) Conduct door and window penetration training or projectile damage testing of doors and windows.

[0025] This application is applicable to security doors, wooden doors, window guardrails, etc. of different sizes and specifications. It can be used for door and window breaching training and to verify the damage effect of projectiles on security doors, wooden doors, and window guardrails. At the same time, this application has the advantages of simple structure, reliable operation, good compatibility, and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] Figure 3 Schematic diagram of the door and window breakthrough simulation system according to an embodiment of the present application. Figure 3 As shown, the simulation system includes a base 1, two side frames 2 with the same structure, and a plurality of door and window simulations. The two side frames 2 can be relatively movably assembled on the base 1 to form a variable clamping space between the base 1 and the two side frames 2 for selectively clamping any one of the plurality of door and window simulations.

[0037] This application utilizes two relatively movable side frames and a base to form a variable clamping space, so that doors or windows of different specifications and forms can be installed in the clamping space according to actual training or testing needs, expanding the application scenarios of the system and improving the flexibility of the system.

[0038] For example, the door and window simulation objects include at least an iron security door 3, a metal window guardrail 6, a wooden door 7, etc. The door and window simulation objects here can be real iron security doors, metal window guardrails, wooden doors, or products customized for specific training or testing purposes.

[0039] Furthermore, to collect training or test data, one or a combination of data acquisition units, such as force sensors, acceleration sensors, and image acquisition units, may be installed or added to the door or window simulators. Therefore, it is understood that this application also includes a data analysis device for processing the aforementioned data, such as a portable computer, which includes a built-in analysis program that uses a preset algorithm or model to analyze the training or damage effects based on the aforementioned data.

[0040] Figure 4 Schematic diagram of the base structure according to the embodiment of the present application. Figure 4As shown, the base 1 is a rectangular frame with an axisymmetric structure. The middle positions of the two short sides of the rectangular frame are connected by a T-shaped guide groove 12, and the two long sides of the rectangular frame are respectively provided with bolt guide grooves 13.

[0041] To improve the stability and strength of the rectangular frame, the T-shaped guide groove 12 is connected to the bolt guide grooves 13 on both sides thereof through ribs 11 . Preferably, the ribs 11 are arranged in the middle of the T-shaped guide groove 12 and the bolt guide groove 13 .

[0042] For example, Figure 4 As shown, the T-shaped guide slot 12 is an open structure with an upward opening and a convex cross-section (concave T-shape), meaning the width of the top opening is smaller than the width of the bottom. The cross-section of the bolt guide slot 13 is similar to that of the T-shaped guide slot 12, but its cross-sectional dimensions are smaller.

[0043] For example, Figure 4 As shown, the bottom of the T-shaped guide rail groove 12 has substantially the same height as the top of the bolt guide rail groove 13 , so that the T-shaped guide rail groove 12 is higher than the bolt guide rail groove 13 as a whole.

[0044] Optionally, the base 1 is formed by welding aluminum alloy or stainless steel angle steel, or adopts a wooden structure.

[0045] Figure 5 Schematic diagram of the side frame structure according to the embodiment of the present application. Figure 1 、 Figure 5 The side frame 2 includes an L-shaped bracket, and the horizontal part and the vertical part of the bracket are respectively provided with continuous mounting grooves on the inner corner sides of the bracket. When the two side frames are assembled on the base 1 with the inner corner sides facing each other, the two vertical mounting grooves and the two horizontal mounting grooves jointly define a clamping space for fixing the door and window simulation object.

[0046] Exemplarily, the bottom surface of the horizontal portion of the bracket extends downward to form a T-shaped guide rail 23 that is adapted to the T-shaped guide rail groove 12 of the base 1. The T-shaped guide rail 23 and the T-shaped guide rail groove 12 form a sliding mechanism so that the side frame 2 can be relatively movably assembled on the base 1.

[0047] Furthermore, the T-shaped guide rail 23 is located directly below the bottom surface of the horizontal part of the bracket, and its front end surface along the assembly direction is set rearward relative to the end surface of the horizontal part of the bracket, thereby facilitating accurate alignment when installing door and window simulations, while expanding the range of variation of the clamping space.

[0048] The two sides of the horizontal portion of the bracket extend laterally to form a horizontal arm. Bolt mounting holes are provided at the ends of the horizontal arms. The head of a T-bolt 5 is installed in the bolt guide slot 13 of the base 1. The bolt passes through the bolt mounting hole at the end of the horizontal arm and is connected to the nut 4. When adjusting the assembly position of the side frame 2 on the base 1, the T-bolt 5 slides freely in the bolt guide slot 13, thereby assisting the sliding mechanism formed by the T-rail 23 and the T-rail slot 12, making the movement of the side frame 2 more stable and smooth. Once the side frame 2 is moved into position on the base 1, the nut 4 is tightened to lock the end of the horizontal arm with the bolt guide slot 13 of the base 1, allowing the two side frames 1 to stably and reliably clamp the door and window simulation.

[0049] Furthermore, the horizontal support arm forms a bending structure at the end near the horizontal part of the bracket, and the bending structure includes a horizontal section connected to the side of the horizontal part of the bracket and a vertical section for connecting the horizontal section to the horizontal support arm part. The length of the horizontal section meets the following conditions: when the T-shaped guide rail 23 is assembled in the T-shaped guide rail groove 12, the inner side surface of the vertical section partially overlaps with the outer side surface of the T-shaped guide rail groove 12 in the vertical direction and fits with an appropriate clearance in the horizontal direction, thereby further improving the stability and guiding accuracy of the sliding mechanism, and at the same time further improving the stability of the side frame along the lateral direction.

[0050] For example, in order to further improve the overall strength and stability of the side frame, the rear end of the T-shaped guide rail 23 is connected to the rear side of the upper end of the vertical part of the bracket through a rear rib plate, and the two ends of the horizontal support arm are respectively connected to the two sides of the upper end of the vertical part of the bracket through a side rib plate.

[0051] Continue to refer to Figure 5 In another example, a second mounting groove with a predetermined length is formed at the bottom of the mounting groove of the vertical part of the bracket in the vertical direction, and the two second mounting grooves of the two side frames jointly define a second clamping space for fixing the door and window simulation object, which is used to install the metal window guardrail 6.

[0052] Reference Figure 6 The mounting grooves of the horizontal and vertical parts of the side frames are formed by continuous guard wings 26 on both sides, which block and restrict the sides and bottom edges of door and window simulations, such as iron security doors 3 and wooden doors 7, to prevent the door panels from tipping over and moving.

[0053] Figure 7 、 Figure 8 As an example of applying this application, Figure 7 、 8 As shown, the door and window simulation in this example is a metal security door. When using this system for door and window breaching training or testing the damage effect of projectiles on doors and windows, the system assembly process is as follows:

[0054] (1) Place the base 1 on the ground;

[0055] (2) Slide the convex T-shaped guide rail 23 of the side frame 2 along the concave T-shaped guide rail 12 into the base 1;

[0056] (3) Install the bolt 5 and nut 4, and keep the nut 4 loose so that the T-bolt 5 connected to the end of the horizontal support arm of the side frame can slide freely in the bolt guide groove 13;

[0057] (4) Install the iron anti-theft door 3 in the installation slot of one of the side frames 2;

[0058] (5) Move the other side frame 2 or move both at the same time to clamp the iron anti-theft door 3 in the clamping space defined by the two side frames;

[0059] (6) Tighten the nut 4 to lock the side frame 2 and the base 1;

[0060] (7) Conduct door and window penetration training or projectile damage testing of doors and windows.

[0061] After the training or test is completed, if the object needs to be replaced, the current object is removed according to the reverse process of the above steps, and then another object is replaced according to the above steps to perform training or testing again.

[0062] After the training or test is completed, the data analysis device is used to analyze the training or test effect based on the data collected by the data collection unit.

[0063] Figure 9 For another example of applying this application, Figure 9 As shown, the door and window simulation in this example is a metal window guardrail. When using the system for door and window breach training or testing the damage effect of projectiles on doors and windows, the system assembly process is as follows:

[0064] (1) Place the base 1 on the ground;

[0065] (2) Slide the convex T-shaped guide rail 23 of the side frame 2 along the concave T-shaped guide rail 12 into the base 1;

[0066] (3) Install the bolt 5 and nut 4, and keep the nut 4 loose so that the T-bolt 5 connected to the end of the horizontal support arm of the side frame can slide freely in the bolt guide groove 13;

[0067] (4) Install the metal window guardrail 6 into the second mounting groove of one of the side frames 2;

[0068] (5) Move the other side frame 2 or move both at the same time to clamp the metal window guardrail 6 in the second clamping space defined by the two side frames. At this time, the upper and lower ends of the metal window guardrail 6 are also clamped with the upper and lower ends of the second mounting groove respectively;

[0069] (6) Tighten the nut 4 to lock the side frame 2 and the base 1;

[0070] (7) Conduct door and window penetration training or projectile damage testing of doors and windows.

[0071] Similarly, after training or testing is completed, if you need to replace other models of window guardrails, such as different widths, you can remove the current window guardrail according to the reverse process of the above steps, and then replace it with another window guardrail according to the above steps to conduct training or testing again.

[0072] Figure 10 For another example of applying this application, Figure 10 As shown, the door and window simulation in this example is a wooden door. When using the system for door and window breakthrough training or testing the damage effect of projectiles on doors and windows, the system assembly and operation process is the same as Figure 7 、 Figure 8 The examples shown are similar and will not be repeated here.

[0073] This application is suitable for clamping security doors, wooden doors, window guardrails, etc. of different sizes and specifications. It can be used for door and window breaching training and to verify the damage effect of projectiles on security doors, wooden doors, and window guardrails. At the same time, this application has the advantages of simple structure, reliable operation, good compatibility, and low cost.

[0074] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
