Description

Technical Field

[0001] The invention relates to the technical field of oxygen bombs, in particular to a laser ignition oxygen bomb. Background Art

[0002] Laser-ignited oxygen bombs are widely used in experimental analysis and industrial production to measure the calorific value of materials. However, the existing technology has many drawbacks, which restrict its further development and application.

[0003] The laser head replacement process for existing laser ignition oxygen bombs is complex. Its integrated or nested connection structure requires specialized tools for complex operation, and disassembly can easily damage other components. This not only increases maintenance costs but also severely impacts equipment efficiency, leading to experimental and production interruptions. Regarding thermal conductivity, due to a lack of scientifically designed thermal paths, the heat generated by the laser head is difficult to effectively transfer to the oxygen bomb barrel. Localized heat accumulation leads to uneven temperatures, resulting in incomplete sample combustion and reduced experimental accuracy. High temperatures can also damage internal components of the oxygen bomb, shortening the equipment's lifespan.

[0004] Under high temperature and high pressure, the oxygen filling mechanism and ignition components of existing oxygen bombs are prone to loosening and seal failure, causing oxygen leakage. At the same time, high temperature and high pressure will also damage the electronic and optical components of the laser ignition mechanism, resulting in a low ignition success rate and an inability to meet the requirements of use under extreme conditions. In addition, the laser head installation method makes it difficult to ensure precise positioning and close contact. It is easily affected by vibration and temperature changes and prone to poor contact, resulting in unstable power supply and laser energy fluctuations, affecting the ignition effect and posing a safety hazard. It has poor sealing and weak waterproofing. In humid environments or liquid operation scenarios, moisture and impurities intrusion can easily corrode internal components, causing circuit shorts and degraded optical component performance, limiting the application scenarios of the equipment.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Convenient and efficient replacement of the laser head: Compared with the complex integrated or nested connection of the laser head in the prior art, the present invention adopts a modular installation design of the laser base. Several mounting holes set on the top edge of the laser base are precisely adapted to the mounting base at the bottom of the oxygen bomb, and can be quickly disassembled and assembled by screws. When replacing the laser head, there is no need to use special tools, nor is there any need to perform complex disassembly of other core components of the oxygen bomb. Only the screw needs to be unscrewed to disassemble and replace the laser base and the laser head as a whole, which greatly shortens the maintenance time, reduces the difficulty and cost of maintenance, and significantly improves the maintainability and efficiency of the equipment.

[0024] 2. Excellent Thermal Conductivity: This invention establishes a scientific and efficient thermal conductivity system, completely resolving the poor thermal conductivity of existing oxygen bombs. The glass column, as the core thermal conductive component, leverages its excellent light transmittance and thermal conductivity to rapidly and evenly transfer heat generated by the laser head into the oxygen bomb barrel while transmitting laser energy. Furthermore, the glass upper and lower pads work closely with the glass column to further optimize the thermal conduction path, minimize heat loss, and avoid localized heat accumulation. This design ensures uniform temperature distribution within the oxygen bomb, ensuring full and stable combustion of the sample, significantly improving the accuracy and reliability of test results.

[0025] 3. Double protection ensures stable contact: Through the secondary protection structure of springs and countersunk holes, this invention effectively solves the problem of poor contact of existing laser heads. The vertically arranged laser electrode on the laser head is precisely matched with the countersunk hole on the laser insulation pad, achieving precise positioning and stable connection, providing a reliable power supply foundation for the laser head; the spring installed on the outer surface of the laser head is connected to the top of the laser head at one end and abuts the glass upper pad at the other end. The elastic pressure of the spring keeps the laser head in close contact at all times. Even under complex working conditions such as equipment vibration and temperature changes, it can ensure stable contact between the laser head and various components, guaranteeing stable output of laser energy and significantly improving ignition reliability.

[0026] Fourth, a triple waterproof protection system: To address the poor sealing and water-prone nature of existing oxygen bombs, this invention innovatively designs a three-stage waterproof structure consisting of an outer glass pad, an upper glass pad, and a lower glass pad. The outer glass pad fits tightly against the laser housing and laser base, while the upper and lower glass pads are located at the top and bottom of the glass column, filling the gaps between components and forming a multi-layered waterproof barrier. This rigorous waterproof design effectively blocks moisture and impurities from entering the oxygen bomb, preventing damage to internal electronic and optical components due to moisture, significantly enhancing the oxygen bomb's adaptability and stability in humid environments or liquid operations.

[0027] 5. Anti-fouling protection for the glass column: The upper, lower, and outer glass pads installed around the periphery of the glass column not only provide water resistance but also effectively prevent dust, impurities, and corrosive substances from contacting the glass column surface. This prevents contamination of the glass column, which could lead to a decrease in light transmittance or damage to its optical properties. This ensures that the laser can smoothly penetrate the glass column and accurately focus on the sample, providing reliable guarantees for stable ignition and accurate testing, and extending the service life of the oxygen bomb's key components.

[0051] In this embodiment, an oxygen bomb spacer 41a is provided on the laser seat 41, and the oxygen bomb spacer 41a is provided between the top of the laser seat 41 and the bottom of the oxygen filling valve seat 31;

[0052] Specifically, a laser insulating pad 41b is provided inside the oxygen bomb spacer 41a, and the laser insulating pad 41b is arranged between the top of the laser seat 41 and the bottom of the oxygen filling valve seat 31; the laser insulating pad 41b and the oxygen bomb spacer 41a isolate the unnecessary heat conduction path between the laser seat 41 and the oxygen filling valve seat 31, thereby preventing high temperature from affecting the oxygen filling mechanism and extending the life of internal components.

[0053] In this embodiment, a countersunk hole 41c is provided on the laser insulating pad 41b, and the size of the countersunk hole 41c is adapted to the laser electrode 421, and the laser electrode 421 is arranged in the countersunk hole 41c; by embedding the laser electrode 421 into the countersunk hole 41c of the laser insulating pad 41b, the size of the countersunk hole is adapted to the electrode, thereby ensuring precise coaxial positioning of the laser head 42 during installation, and avoiding ignition failure caused by offset; the countersunk hole structure also limits the lateral displacement of the electrode, and cooperates with the axial clamping force of the spring 42a to ensure the tightness of the electrical connection under vibration and temperature changes, stabilize the power supply and laser energy output, and reduce safety hazards, such as the risk of electric sparks caused by poor contact.

[0054] In this embodiment, a glass upper pad 43a is provided on the top of the glass column 43, and the glass upper pad 43a is located between the bottom of the laser head 42 and the top of the glass column 43; a glass lower pad 43b is provided at the bottom of the glass column 43, and the glass lower pad 43b is located between the bottom of the glass column 43 and the laser cover 44.

[0056] By providing a spring 42a on the outer surface of the laser head 42, with one end connected to the top of the laser head and the other end abutting the glass upper pad 43a, the heat conduction efficiency between the laser head and the glass column 43 is enhanced through elastic contact; the glass column 43, the glass upper pad 43a, and the glass lower pad 43b form a continuous heat conduction path, which quickly conducts the heat of the laser head to the oxygen bomb 2, avoiding the problem of insufficient sample combustion caused by local heat accumulation, and improving the accuracy of experimental data.

[0057] In this embodiment, a glass outer pad 44a is provided on the laser outer cover 44, and the glass outer pad 44a is disposed close to the top of the laser outer cover 44 and the bottom of the laser base 41;

[0059] In this embodiment, the laser base 41 is provided with a plurality of mounting holes 41d, each of which is located close to the top edge of the laser base 41. A mounting base 11a is provided at the bottom of the oxygen warhead 11 to match the mounting holes 41d. The laser base 41 is fixed to the bottom of the oxygen warhead 11 by a screw passing through the mounting holes 41d.

[0060] The laser base 41 is fixed to the bottom of the oxygen bomb 11 through the mounting hole 41d and the screw, replacing the existing integrated or nested structure. The laser head 42 can be quickly disassembled and replaced without professional tools, avoiding damage to other components during the disassembly process, significantly reducing maintenance costs (reducing component loss) and equipment downtime (improving usage efficiency), and avoiding interruptions to experiments / production.

[0061] In this embodiment, a large oxygen bomb nut 31a is provided on the top of the oxygen filling valve seat 31; the oxygen filling valve seat 31 is fixed to the central axis of the oxygen bomb head 11 through the large oxygen bomb nut 31a; the oxygen filling valve seat 31 is also provided with a small oxygen bomb pressure ring 31b and a steel ring 31c, the steel ring 31c is located between the top of the oxygen bomb head 11 and the bottom of the large oxygen bomb nut 31a, and the small oxygen bomb pressure ring 31b is located between the top of the steel ring 31c and the bottom of the large oxygen bomb nut 31a.

[0062] The oxygen filling valve seat 31 is fixed to the oxygen bomb head 11 through the combined structure of the oxygen bomb large nut 31a, the steel ring 31c, and the oxygen bomb small pressure ring 31b.

The through hole 111a is strictly coaxial with the laser head 42 and the crucible 11d to ensure that the laser beam penetrates the fire stop plate without obstruction and is directly focused on the sample in the crucible, thereby avoiding ignition failure caused by energy loss or offset.

[0064] In this embodiment, the oxygen warhead 11 and the mounting base 11a are of an integrated structure.

[0065] Example 2

[0066] like Figures 2 to 5 As shown, in the further improvement of the above embodiment 1,

[0067] A large oxygen bomb pressure ring 111 and a large sealing ring 112 are provided between the bottom of the oxygen bomb 11 and the cartridge cover 1. The large sealing ring 112 is provided between the bottom of the cartridge cover 1 and the oxygen bomb 11. The large oxygen bomb pressure ring 111 is provided between the top of the large sealing ring 112 and the bottom of the cartridge cover 1.

[0068] Specifically, an electrode sealing ring 5 is further provided on the laser electrode 421 , and the electrode sealing ring 5 is located between the outer surface of the laser electrode 421 and the countersunk hole 41 c.

[0069] By adding a large pressure ring 111, a large sealing ring 112, and an electrode sealing ring 5 structure, and through the triple mechanism of "mechanical compression, material sealing, and stress dispersion", the leakage risk, electrode reliability, and structural stability problems of the existing oxygen bomb in a high-pressure environment are solved.

[0070] Through the electrode sealing ring 5, the technical difficulty of "sealing protection of electrical connections" in the laser ignition mechanism has been specifically overcome, making the equipment adaptable to complex scenarios such as high pressure, high temperature, humidity, and vibration (such as chemical reactors and combustion experiments in deep-sea exploration equipment), significantly improving the industrial applicability and safety of the laser ignition oxygen bomb.

[0071] Working principle of the present invention:

[0072] Oxygenation process: high-pressure sealed oxygen supply;

[0073] The oxygenation mechanism is connected to an external oxygen source through the oxygenation nozzle 32 on the top of the oxygenation valve seat 31 , and oxygen flows into the symmetrical oxygenation channel 311 at the bottom of the oxygenation valve seat through the oxygenation valve core 33 and is finally evenly injected into the oxygen cartridge 2 .

[0074] Sealing mechanism: The oxygen filling valve seat is fixed to the oxygen bomb 11 through the combination of the oxygen bomb large nut 31a, the steel ring 31c and the oxygen bomb small pressure ring 31b. The elastic deformation of the steel ring 31c and the uniform compression force of the small pressure ring 31b form a high-pressure seal to prevent oxygen leakage; the oxygen bomb large pressure ring 111 and the large sealing ring 112 at the bottom of the oxygen bomb further strengthen the overall sealing between the oxygen bomb and the cartridge cover, ensuring that there is no gas leakage under high-pressure environment (such as 20MPa).

[0075] Ignition process: precise laser ignition;

[0076] The laser ignition mechanism is fixed to the bottom of the oxygen filling valve seat through the laser seat 41. The laser emitted by the laser head 42 is transmitted to the crucible 11d below (coaxially arranged with the laser head) through the glass column 43 to ignite the sample.

[0077] Positioning and conductivity: The laser electrode 421 is embedded in the countersunk hole 41c of the laser insulating pad 41b. The countersunk hole size is adapted to the electrode to ensure precise coaxial positioning during laser head installation; the electrode sealing ring 5 on the outer surface of the electrode fills the gap, which not only fixes the electrode to prevent deviation, but also isolates oxygen from contact with the electrode to avoid short circuit.

[0078] Energy conduction: The spring 42a on the outer surface of the laser head abuts the glass upper pad 43a, enhancing the heat conduction efficiency between the laser head and the glass column through elastic contact; the glass column 43, the glass upper pad 43a, the glass lower pad 43b and the glass outer pad 44a form a continuous heat conduction path, which quickly conducts the heat of the laser head to the oxygen bomb cylinder to ensure sufficient combustion of the sample.

[0079] Structural protection: multi-layer sealing and anti-interference design;

[0080] Insulation and heat insulation: The oxygen bomb spacer 41a and the laser insulation pad 41b isolate the unnecessary heat conduction path between the laser seat and the oxygen filling valve seat to prevent high temperature from affecting the oxygen filling mechanism; the laser insulation pad also serves as an insulating support for the electrode to avoid current leakage.

[0081] Environmental protection: The enclosed structure of the laser cover 44, combined with the insulating properties of the glass column, and the multi-layer physical barriers such as oxygen bomb spacers, laser insulation pads, glass pads, and electrode sealing rings, prevent moisture and impurities from invading the interior of the laser head, thereby improving the equipment's waterproof and corrosion resistance in humid, dusty environments.

[0082] Maintenance convenience: modular and quick disassembly and assembly;

[0083] Laser base 41 is secured to the bottom of oxygen bomb 11 via mounting holes 41d and screws, forming a modular structure. When the laser head needs to be replaced, the screws can be quickly disassembled without specialized tools, allowing the laser base and internal laser head components to be removed separately. This avoids damage to other components during disassembly of traditional integrated structures, significantly reducing maintenance costs and equipment downtime.

[0084] Adaptability to extreme environments;

[0085] High-pressure impact resistance: The multiple sealing structures (steel ring, pressure ring, sealing ring) of the oxygen charging mechanism and the oxygen warhead can withstand high temperature and high pressure (such as the impact generated by combustion and explosion). The mechanical support of the steel ring and pressure ring disperses stress and prevents component deformation; the rigid support structure of the laser cover and glass column protects the optical elements from damage due to high-pressure impact.

[0086] Vibration and temperature stability: The elastic compression force of spring 42a and the positioning function of countersunk hole 41c ensure that the laser head maintains a tight electrical connection when it vibrates or experiences sudden temperature changes, stably outputting laser energy and avoiding ignition failure or safety hazards caused by poor contact.
