[0002] Explosive destruction technology is a method for safely disposing of expired explosive items. Traditional destruction technologies include detonation, incineration, chemical decomposition, etc. Among them, the incineration method requires a dedicated incinerator body, and the explosive is incinerated in the incinerator body. The incinerator body is about 3-4m high. Before incineration, the explosive needs to be put into the incinerator body through a packaging bag, and then the ignition and incineration operation is carried out.

[0003] The existing incinerator body has the following problems: during incineration treatment, the form of laser ignition is usually adopted, and a laser igniter is set at the top of the furnace body to normally emit laser to ignite the explosive in the furnace body. Due to the height of the incinerator body, although not all the substances generated by the explosive will collide with the laser igniter, inevitably, the explosion impact force is large, and still some substances may splash, resulting in damage to the laser igniter. Content of the Utility Model

DETAILED DESCRIPTION

[0031] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

Additionally, to simplify the drawings for better understanding, in some figures, only one of the components with the same structure or function is schematically shown, or only one of them is labeled. In this article, "one" not only means "only this one" but also can mean "more than one" situation, and "several" includes "two" and "more than two".

[0033] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "install", "connect", and "join" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific situations.

[0034] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0035] Referring to Figures 1 to 3 , as the first embodiment of the present utility model, an explosive laser ignition device is proposed, including:

[0036] A protection seat 1, the top and bottom of the protection seat 1 respectively have a first installation part 101 and a second installation part 102, and the protection seat 1 also has a laser protection channel 103, the laser protection channel 103 is located between the first installation part 101 and the second installation part 102, and further includes:

[0037] A laser ignition part 2, the laser ignition part 2 is arranged on the first installation part 101.

[0038] In this embodiment, as Figures 1 to 3 shown, usually, when the laser ignition device is used to perform the ignition operation of a specific incinerator, it is set at the top. On the one hand, it ensures that the laser can smoothly hit the ignition area inside the furnace body. On the other hand, relying on the height of the furnace body, it avoids the explosion powder moving upward and impacting the laser ignition device, resulting in damage to the device. However, it still cannot avoid the phenomenon that some substances may still collide with the laser ignition device. Therefore, an explosive laser ignition device is designed.

[0039] Specifically, a protective seat 1 is installed between the laser ignition component 2 and the incinerator body to play a protective role. The top and bottom of the protective seat 1 are provided with a first mounting portion 101 and a second mounting portion 102, which can be specifically in the form of a flange, etc. The second mounting portion 102 at the bottom is used to mount the protective seat 1 as a whole on the incinerator body, and the first mounting portion 101 is convenient for fixed connection with the laser ignition component 2 to complete the mechanism ignition operation. The cleverness of this design lies in that the laser protection channel 103 of the protective seat 1 is arranged between the top and bottom of the protective seat 1, and the height of the entire protective seat 1 is fully utilized to avoid the phenomenon of collision between some materials and the laser ignition component 2 as much as possible, thereby greatly improving the safety protection performance of the laser ignition component 2. At the same time, the entire protective seat 1 also adopts a steel structure or aluminum material to improve the overall structural stability.

[0040] Furthermore, the laser protection channel 103 is in a frustum shape, and the cross-sectional area of the laser protection channel 103 gradually increases from being close to to being far away from the first mounting portion 101 .

[0041] In this embodiment, Figures 1 to 3 As shown, the frustum-shaped design of the laser protection channel 103, specifically, the cross-sectional area of the frustum-shaped laser protection channel 103 gradually increases from the position close to the first mounting portion 101. This design is helpful for the stable focusing and diffusion control of the laser beam during the transmission process. When the laser passes through the gradually increasing channel, its beam diameter can be naturally adjusted to avoid direct irradiation on the laser ignition element 2 to generate overheating or energy concentration, resulting in unexpected local damage or premature detonation. In addition, this design can also effectively reduce the impact of external interference (such as dust, moisture, etc.) on laser transmission, ensuring the accuracy and stability of laser ignition.

[0042] Furthermore, the protection seat 1 comprises:

[0043] A base 104, wherein the base 104 has the laser protection channel 103, and the bottom of the base 104 has the second mounting portion 102;

[0044] The mounting cover 105 has the first mounting portion 101 on the top thereof, and the mounting cover 105 is disposed on the base 104 .

[0045] Furthermore, the protection seat 1 also includes:

[0046] The thermal insulation pad 106 , the mounting cover 105 is arranged on the base 104 through the thermal insulation pad 106 , the thermal insulation pad 106 has a through hole 107 , the through hole 107 is connected to the laser protection channel 103 , and the thermal insulation pad 106 is located between the laser ignition component 2 and the base 104 .

[0047] In this embodiment, Figures 1 to 3As shown, the application of the dual mounting structure and the heat insulation pad 106. Specifically, the protection base 1 consists of a base 104, a mounting cover 105, and a heat insulation pad 106. The split design of the base 104 and the mounting cover 105, and the isolation of high temperature through the heat insulation pad 106 greatly improve the thermal management ability of the device. The heat insulation pad 106 can not only prevent high temperature from being transferred to other sensitive components and extend the service life of the equipment, but also ensure the unobstructed laser channel through the through hole 107, achieving a balance between high performance and safety. The use of the heat insulation pad 106 also simplifies the maintenance and replacement process of the device and improves the operability of the overall system.

[0048] Further, the bottom of the mounting cover 105 has a protection groove 108, and the protection groove 108, the through hole 107, and the laser protection channel 103 are sequentially connected. It further includes:

[0049] A laser protection part 3, and the laser protection part 3 is arranged in the protection groove 108.

[0050] Further, the laser protection part 3 includes:

[0051] A protective glass plate 301 and a sealing ring 302. Both the protective glass plate 301 and the sealing ring 302 are arranged in the protection groove 108, and the sealing ring 302 is located between the protective glass plate 301 and the heat insulation pad 106.

[0052] Further, the laser protection part 3 further includes:

[0053] A rubber buffer 303, and the rubber buffer 303 is arranged in the protection groove 108, and the protective glass plate 301 is located between the rubber buffer 303 and the sealing ring 302.

[0054] In this embodiment, as Figures 1 to 3 shown, further on the mounting cover 105 where the laser ignition part 2 is located, a laser protection part 3 for protection is additionally provided and arranged in the internal protection groove 108. Specifically, the laser protection part 3 includes a protective glass plate 301, a sealing ring 302, and a rubber buffer 303. This combination constitutes a highly secure laser transmission system. The protective glass plate 301, as the direct contact surface of the laser, effectively blocks the fragments generated by the explosion and protects the internal precision components. The sealing ring 302 ensures the sealing of the laser channel and prevents external environmental factors from interfering with the laser performance; the rubber buffer 303 absorbs the shock wave that may be generated during the laser ignition instant, further ensuring the stability and safety of the laser ignition part 2 and the entire device.

[0055] The use of the heat insulation pad 106 and the sealing ring 302 improves the device's resistance to harsh environments, ensuring high performance under various climatic conditions and operating environments. In addition, compared with traditional chemical ignition methods, laser ignition reduces the emission of harmful substances, is more environmentally friendly, and meets the pursuit of sustainable development in modern industry. The rubber buffer 303 absorbs the shock waves that may be generated during laser ignition, further ensuring the stability and safety of the laser ignition component 2 and the entire device.

[0056] The modular design concept of the entire laser protection component 3 makes it easy to maintain and upgrade. For example, if the laser ignition component 2 or the protective glass plate 301 wears out due to long-term use, they can be replaced through simple disassembly and assembly steps without replacing the entire device. This not only reduces maintenance costs but also ensures the long-term efficient operation of the device.

[0057] Furthermore, it further includes:

[0058] The connecting fastener 4, and the connecting fastener 4 penetrates through the mounting cover 105, the heat insulation pad 106, and the base 104.

[0059] In this embodiment, as Figures 1 to 3 shown, the introduction of the connecting fastener 4, by penetrating through the mounting cover 105, the heat insulation pad 106, and the base 104, not only strengthens the stability of the overall structure but also ensures the connection accuracy of the entire protection seat 1, and simplifies the assembly and disassembly process, enabling the device to maintain a reliable working state under harsh environments.
