Description

Technical Field

[0001] This invention belongs to the technical field of energy-containing device destruction equipment, and specifically relates to an integrated laser destruction device and a method for destroying energy-containing devices. Background Technology

[0002] Currently, laser destruction has become an important method for handling energetic devices, and laser destruction equipment offers advantages such as long-distance, non-contact, and safe processing. Here, "energetic devices" broadly refers to hazardous materials, equipment, or devices that pose an explosive or flammable hazard. Existing portable laser destruction equipment for energetic devices mainly suffers from the following problems: First, the equipment deployment layout is not simple. The existing equipment mainly consists of a laser, a laser focusing and emitting device, a battery, a tripod, and a control system. The laser focusing and emitting device and the tripod are connected by threads to form a whole, but the laser and battery are still scattered around.

[0003] Secondly, the equipment connection lines are prone to damage. Because the equipment is distributed over a certain distance, the laser, laser focusing and emitting device and the battery are connected by various types of lines, such as power transmission, fiber optic transmission and signal transmission. These lines are all of a certain length and are prone to bending.

[0004] Third, the equipment has weak overall resistance to tipping over. The tripod support structure is used, but due to the relatively large size and weight of the laser focusing and emitting device, the center of gravity of the support structure is unstable. In addition, the overall weight of the equipment is light, so it is prone to tipping over when used in the field by the wind.

[0005] Fourth, the AI ​​recognition function is lacking. Existing portable laser destruction equipment only has imaging capabilities and does not have the ability to identify energy-containing devices, requiring manual intervention for judgment during use.

[0006] Fifth, its application is limited. When destroying energetic devices in blast holes, the laser equipment can only be deployed at the top of the blast hole due to the protective barrier, which facilitates destruction and subsequent cleanup. Existing portable laser destruction equipment, due to its modular design, is not easily and reliably fixed at the top of the blast hole, affecting the laser destruction effect.

Detailed Implementation

[0022] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0023] like Figure 1As shown in the figure, an integrated laser destruction device provided by an embodiment of the present invention includes a battery 1, a laser 2, a support frame 3, a gimbal 4, and an integrated laser head 5. The lower end of the laser 2 is connected to the battery 1, and the upper end is connected to the bottom of the gimbal 4. The gimbal 4 is disposed on the top of the support frame 3. The laser emitted by the laser 2 passes sequentially through the gimbal 4 and the integrated laser head 5. The integrated laser head 5 is disposed on the top of the gimbal 4 and is used for identification, recording, ranging, and laser focusing emission. The integrated laser head 5 includes a housing 51 and an internal identification module 52, a camera 53, a rangefinder 54, and a focusing optical path device 50. The camera 52 and the rangefinder 53 are respectively disposed on both sides of the focusing optical path device 50, and the identification module 52 is disposed above the focusing optical path device 50. The bottom of the housing 51 is engaged with the top of the gimbal 4 by a protruding tenon for easy assembly and disassembly. The aforementioned structure enables identification, video recording, and ranging via an integrated laser cannon head, and focuses the laser emitted by the laser source to precisely target energetic devices. This structure results in a simple, compact, safe, reliable, and self-stable laser-based energy destruction device, improving accuracy and facilitating widespread application.

[0024] To further optimize the above structure, an alarm module linked to the laser is also provided. When the identification module detects that a person or animal has accidentally entered the laser irradiation path within the camera's field of view, it directly triggers the alarm module to send a foreign object intrusion signal, and the laser automatically stops emitting laser light.

[0025] In its specific design, the housing adopts a cuboid structure for ease of manufacturing. The pan-tilt unit can be purchased externally and features built-in angle adjustment; during use, the angle of the housing and its internal focusing optical path device can be adjusted as needed. Additionally, the identification module 52, camera 53, and rangefinder 54 can all be purchased externally.

[0026] As a preferred structure, such as Figure 2 and Figure 3 As shown, the top of the housing 51 is equipped with a display screen 55 and control buttons 56. The display screen 55 is electrically connected to the recognition module 52, camera 53, and rangefinder 54. The recognition module 52 is an image recognition module. The top of the housing 51 is provided with a rectangular groove 57 to accommodate the display screen 55. The lower end of the display screen 55 is rotatably connected to one side wall of the groove 57. When in use, the display screen 55 can be lifted to observe the image, detection data, and focus status. When not in use, it is snapped into the groove 57 and pressed and fixed on both sides with rotating pressure plates 58. The display screen, image recognition module, camera, and rangefinder can be purchased according to actual needs. The display screen can intuitively display the image recognized by the image recognition module, the image captured by the camera, and the detection results of the rangefinder. The control buttons 56 control the start and stop of the main power supply, laser, camera, and rangefinder.

[0027] In specific embodiments of the present invention, such as Figure 4 As shown, the focusing optical path device 50 includes a first focusing lens 501, a first beam splitter 502, a second beam splitter 503, a reflector 504, a second focusing lens 505, and a collimating lens 506. The first focusing lens 501 and the first beam splitter 502 are sequentially disposed above the laser 2. The first beam splitter 502 and the second beam splitter 503 are horizontally arranged side by side. A reflective film 509 is provided on the side wall of the first beam splitter 502 for reflecting the laser to the second beam splitter 503. The reflector 504 is disposed on the side of the second beam splitter 503. The second focusing lens 505 is disposed between the reflector 504 and the laser aperture 510 on the housing 51. The collimating lens 506 is disposed on the side of the second beam splitter 503, and the two are arranged parallel to each other. An image sensor 507 for calibrating the laser level is provided on the side of the collimating lens 506. The image sensor 507 is connected to the display screen 55. The laser emitted by laser 2 is focused by the first focusing lens 501, then reflected by the first beam splitter 502 to the second beam splitter 503, then reflected by the second beam splitter 503 to the reflector 504, then reflected by the reflector 504 to the second focusing lens 505, and finally focused by the second focusing lens 505 before exiting through the laser aperture 510. Similarly, the light from the energetic device can be reflected sequentially by the second focusing lens 505, the reflector 504, and the second beam splitter 503 into the first beam splitter 502, then reflected by the reflective film 509 on the side of the first beam splitter 502, and then by the second beam splitter 503 and the collimating lens 506 into the image sensor, thereby calibrating the shooting accuracy. Figure 4 The hollow arrow indicates the light path of the light emitted by the energetic device, and the arrow indicates the laser light path.

[0028] Further optimize the above solution, such as Figure 4 As shown, a filter 508 is also provided between the collimating lens 506 and the image sensor 507 to avoid the influence of stray light on the results and improve the accuracy of the calibration of the energetic device.

[0029] In specific design, such as Figure 1 , 4 As shown, the laser 2 is a small, cylindrical, air-cooled fiber laser. The upper end of the laser 2 has a cylindrical connector 20, which is threadedly connected to the pan-tilt unit 4. The middle of the connector 20 has a laser outlet 21. The pan-tilt unit 4 has multiple through holes for the laser and cables to pass through. The threaded connection between the laser 2 and the pan-tilt unit 4 allows for convenient and quick assembly and disassembly. Power transmission, fiber optic transmission, and signal transmission between the integrated laser head, laser, pan-tilt unit, and battery are achieved through short cables. The cables pass through the through holes without being exposed, resulting in a more compact and neat overall structure.

[0030] Meanwhile, the battery 1 is a small, high-density cylindrical energy storage battery. The upper end of the battery 1 is threadedly connected to the laser 2, and a conductive plate is provided at the upper end of the battery 1 for electrical connection to the power input terminal at the lower end of the laser 2. Similarly, the threaded connection between the cylindrical battery 1 and the cylindrical laser 2 makes full use of the internal space of the support frame, making the overall structure more compact and convenient for assembly and disassembly.

[0031] In specific embodiments of the present invention, such as Figure 1 As shown, a buffer net 6 is provided on the inner side of the support frame 3, and the edges of the buffer net 6 are fixed at intervals to the middle of the support frame 3; the buffer net 6 is located below the battery 1. The buffer net 6 can be made of nylon mesh, which can prevent the laser and battery from being accidentally dropped and damaged during installation and dismantling, thus providing protection.

[0032] In the specific design, the support frame 3 is an optical tripod, and the three legs 30 of the optical tripod are all telescopic structures, which are convenient for storage and carrying.

[0033] Further optimize the above solution, such as Figure 1 As shown, the bottom of the support leg 30 is equipped with an anchor rod 7 with a conical tip at the lower end, and an umbrella-shaped fixing plate 8 is fitted onto the top of the anchor rod 7. The anchor rod and the lower end of the support leg 30 are connected by threads for easy installation and removal. The anchor rod can be inserted into the ground to improve the stability of the equipment. In snowy weather, the fixing plate 8 can increase the contact area with the snow surface, further increasing the stability of the equipment.

[0034] The present invention also provides a method for destroying an energetic device, comprising the following steps: S1. Marking: Upon discovering an energy-containing device, immediately mark it with a distinctive object such as a small red flag; S2. Setting up a protective cage: Multiple energy-containing devices are placed at intervals inside the protective cage. The bottom plate of the protective cage is provided with multiple fixing slots for accommodating the energy-containing devices at intervals. The protective cage is provided with gaps around its perimeter and top for the laser to pass through. The protective cage is constructed from welded steel bars to form a cuboid or cube, or other hexahedron. The gaps between the steel bars are 0.5mm-1mm to prevent fragments of the energetic device from scattering. A steel plate is welded to the bottom of the protective cage as a base plate to prevent the energetic device from melting due to laser irradiation and flowing out through the gaps at the bottom of the protective cage, thus ensuring incomplete destruction and leaving safety hazards.

[0035] In addition, the fixing slot is a steel component with a "V" cross-section. The advantage of the fixing slot being arranged at intervals is to prevent the sympathetic explosion of energetic devices.

[0036] S3. Install integrated laser destruction equipment: a) The aforementioned integrated laser destruction equipment shall be installed in a location that facilitates the irradiation of energetic devices, while also being conducive to laser focusing and safety protection. Specific requirements are as follows: The distance between the laser and the energetic device is determined based on the device's aperture, propellant charge, terrain, and equipment performance, and is generally not less than 80m. Laser operators should operate and control the equipment from within a personnel shelter, and the distance between the personnel shelter and the laser shelter should meet the requirements of the irradiator's instruction manual.

[0037] The laser destruction equipment shall be installed according to the following procedure: 1) Use a rangefinder to measure the corresponding distance at a location where the energy-containing device is within line of sight, and select the location to install the laser destruction equipment; 2) The laser destruction equipment is placed behind the bunker, so that the laser focusing and emitting device is exposed outside the bunker, ensuring that there is an angle to aim at the energy-containing device.

[0038] b) Adjust the laser to be in normal working condition, and ensure that the laser beam irradiates the energetic device through the gaps in the protective cage.

[0039] S4. Destruction Operation: Start the integrated laser destruction equipment and carry out the laser destruction operation.

[0040] The present invention also provides a method for destroying an energetic device, which is applicable to portable energetic devices, and the steps are as follows: S1. Move the energy-containing device into the explosion hole and place it in the steel detonation groove at the bottom of the explosion hole. The explosion hole is a cylindrical shape with one end open and is made of reinforced concrete.

[0041] The blast hole has an opening on one side to facilitate the entry and exit of target energy devices, personnel, and equipment.

[0042] S2. Install the integrated laser destruction device on the outside of the explosion hole. The integrated laser destruction device is located above the opening end of the explosion hole and in a position that facilitates laser focusing and can irradiate the energy-containing device. S3. Start the integrated laser destruction equipment and carry out the laser destruction operation.

[0043] In summary, the present invention has the following advantages: 1. Simple layout and small footprint. Avoids situations such as people tripping, equipment tipping over, and line damage caused by messy equipment and wiring layout, and facilitates precise on-site management.

[0044] 2. Ingenious structure and high integration. Based on a tetrahedral load-bearing structure, it adopts a tripod suspension method, with the main equipment arranged in a suspended line. This not only makes clever use of the internal space of the tripod but also improves the overall stability of the equipment.

[0045] 3. Functional integration and good scalability. The laser cannon head integrates an intelligent identification module, which can intelligently identify the types of energetic devices, providing support for the rapid generation of destruction strategies. It can also enrich the sample library of energetic devices, update and upgrade training models, and adapt to the diverse disposal needs of energetic devices.
