Description

Technical Field

[0001] This utility model relates to the field of hydrogen-oxygen mixed gas emission technology, and in particular to a hydrogen-oxygen mixed emission tube. Background Technology

[0002] A hydrogen-oxygen mixed emission tube is a device used to emit high-pressure gas. Its core principle is to ignite premixed hydrogen-oxygen gas inside the emission tube, and release a large amount of heat energy through a violent reaction (generating water vapor), producing high-temperature and high-pressure gas, which is then ejected at high speed through the nozzle of the emission tube.

[0003] Currently, existing hydrogen-oxygen hybrid emission tubes cannot adjust the emission mode and have limited functionality. Utility Model Content

[0004] This application discloses a hydrogen-oxygen hybrid emission tube to solve the technical problems of inability to adjust emission modes and limited functionality in related technologies.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] In a first aspect, this application discloses a hydrogen-oxygen mixed emission tube, comprising:

[0007] The storage pipeline has multiple chambers for containing a hydrogen-oxygen mixture;

[0008] The launch tube has a launch channel; one end of the launch channel is connected to the outside, and the other end is connected to multiple chambers.

[0009] A diaphragm assembly, located within the storage conduit, is used to isolate multiple chambers from the emission channel;

[0010] Multiple chambers are used to install spark plugs, which cause the hydrogen-oxygen mixture in the chamber to explode and generate high-pressure gas sufficient to damage the diaphragm assembly.

[0011] In some designs, the diameter of the launch channel gradually decreases from the end closer to the chamber to the end farther away from the chamber.

[0012] In some designs, one chamber is arranged along the axial direction of the storage conduit, while the other chambers are arranged at equal intervals around it.

[0013] In some designs, the storage conduit includes a storage section and a coupling section, with a diaphragm assembly disposed between the storage section and the coupling section;

[0014] The storage chamber is used to contain a hydrogen-oxygen mixture, and the axes of the storage chamber and the coupling chamber are the same.

[0015] In some solutions, the diaphragm assembly includes a connecting portion and multiple diaphragm bodies, with the multiple diaphragm bodies respectively disposed in the connecting portion;

[0016] The connecting part is located between the storage part and the coupling part, and multiple diaphragm bodies are respectively arranged corresponding to the chambers;

[0017] The thickness of the diaphragm body is less than the thickness of the connecting part.

[0018] Secondly, this application also discloses a launch system, including the hydrogen-oxygen mixed launch tube of the first aspect.

[0019] The technical solution adopted in this utility model can achieve the following beneficial effects:

[0020] The hydrogen-oxygen mixture launch tube of this application, when launching high-pressure gas, is activated by a spark plug that ignites the hydrogen-oxygen mixture in the chamber. The hydrogen-oxygen mixture explodes, generating high-pressure gas. This high-pressure gas destroys the diaphragm assembly and is ejected to the outside through the launch channel. Since multiple chambers can be equipped with spark plugs, the multiple spark plugs can be activated simultaneously or sequentially at intervals to adjust the launch mode and meet different launch missions.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0031] The inventors discovered in actual use that the existing hydrogen-oxygen mixed emission tubes control the emission through a single spark plug, which makes it impossible to adjust the emission mode during emission, resulting in a single function.

[0032] The following is in conjunction with the appendix Figures 1 to 3 The present application provides a detailed description of a hydrogen-oxygen hybrid emission tube and emission system through specific embodiments and application scenarios.

[0033] Some embodiments of this application disclose a hydrogen-oxygen mixed emission tube, including a storage conduit 100, an emission conduit 200, and a diaphragm assembly 300.

[0034] like Figure 2 and Figure 3 As shown, the storage conduit 100 has multiple chambers 130 for containing a hydrogen-oxygen mixture. The multi-chamber 130 structure of the storage conduit 100 enables segmented storage and time-sharing or simultaneous ignition of the hydrogen-oxygen mixture through physical isolation, in order to meet the needs of different launch missions.

[0035] like Figure 2As shown, the launch pipe 200 has a launch channel 210; one end of the launch channel 210 is connected to the outside, and the other end is connected to multiple chambers 130. The hydrogen-oxygen mixture from multiple chambers 130 is launched through a single launch channel 210, which reduces the structural complexity of the hydrogen-oxygen mixture launch tube and improves reliability. Furthermore, concentrated injection can increase the airflow velocity; the explosive gases from multiple chambers 130 converge into a single launch channel 210, generating a higher Mach number. In addition, when multiple chambers 130 are ignited at the same time, launching through the same launch channel 210 can superimpose pressure waves, forming a continuous high pressure.

[0036] like Figure 1 and Figure 3 As shown, the diaphragm assembly 300 is disposed in the storage pipe 100 to isolate the multiple chambers 130 from the launch channel 210. Through the presence of the diaphragm assembly 300, its pressure-locking mechanism physically isolates the chambers 130 from the launch channel 210 in the non-launch state, preventing the migration of the hydrogen-oxygen mixture, maintaining a pre-compressed state within the chambers 130, and ensuring that the pressure of the hydrogen-oxygen mixture within the chambers 130 meets the launch requirements.

[0037] Multiple chambers 130 are used to install spark plugs (not shown in the figure). The spark plugs cause the hydrogen-oxygen mixture inside the chamber 130 to explode, generating high-pressure gas sufficient to damage the diaphragm assembly 300. When the high-pressure gas is emitted, the spark plugs are activated and ignite the hydrogen-oxygen mixture inside the chamber 130. The explosion of the hydrogen-oxygen mixture generates high-pressure gas, which damages the diaphragm assembly 300 and is ejected to the outside through the emission channel 210. Since multiple chambers 130 can each be equipped with spark plugs, the multiple spark plugs can be activated simultaneously or sequentially at intervals to adjust the emission mode and meet different emission missions.

[0038] It should be noted that the spark plug in this embodiment is existing technology and is not an improvement of this embodiment. The alignment structure will not be described in detail here.

[0039] In this embodiment, a high-precision clock unit, an ignition control circuit, and multiple ignition drivers constitute a precision timing ignition module for controlling spark plugs. The high-precision clock unit provides an accurate time reference. The ignition control circuit is connected to the high-precision clock unit, receives the clock signal, and generates corresponding ignition control signals according to the preset ignition timing sequence and the ignition commands sent by the control system. Each ignition driver is connected to the ignition control circuit and each spark plug, converting the ignition control signal output by the ignition control circuit into ignition energy suitable for spark plug operation, thus achieving precise ignition control of multiple spark plugs. It should also be noted that the precision timing ignition module in this embodiment is prior art and not an improvement of this application. Furthermore, this is merely an example illustrating the method of igniting multiple spark plugs; therefore, the specific details of the precision timing ignition module are not described in detail in this embodiment.

[0040] like Figure 2 As shown, the diameter of the launch channel 210 gradually decreases from the end near the chamber 130 to the end away from the chamber 130. The tapered diameter design of the launch channel 210 can accelerate the high-pressure gas ejected from the launch channel 210, and the smooth transition of the launch channel 210 avoids stress concentration problems caused by abrupt changes in cross-section, enhances mechanical reliability, and comprehensively optimizes system performance.

[0041] like Figure 2 As shown, one chamber 130 is arranged along the axial direction of the storage pipe 100, and the other chambers 130 are arranged at equal intervals around this chamber 130. The center-surround chamber 130 layout achieves thrust vector synthesis through the synergistic effect of the axial chambers 130 and the circumferential chambers 130. The equidistant distribution allows the blast gas from the multiple chambers 130 to form laminar superposition within the launch channel 210, and the annular redundant layout minimizes the thrust loss rate in the event of a single chamber failure.

[0042] like Figure 1 and Figure 3 As shown, the storage conduit 100 includes a storage section 110 and a coupling section 120, with a diaphragm assembly 300 disposed between the storage section 110 and the coupling section 120. By segmenting the storage conduit 100, after a launch mission, the damaged diaphragm assembly 300 can be quickly replaced and the chamber 130 can be cleaned by separating the storage section 110 and the coupling section 120, reducing maintenance time.

[0043] In this embodiment, the chamber 130 of the storage unit 110 is used to contain the hydrogen-oxygen mixture, and the axes of the chamber 130 of the storage unit 110 and the chamber 130 of the coupling unit 120 are the same. Because the axes of the chamber 130 of the storage unit 110 and the chamber 130 of the coupling unit 120 are the same, after the hydrogen-oxygen mixture is ignited to generate high-temperature gas, the high-temperature gas that breaks through the diaphragm assembly 300 can directly enter the second storage chamber 130 in a straight line, avoiding turbulence, vortices and local resistance losses caused by flow path deflection or abrupt changes in cross-section, thereby significantly reducing the dissipation of gas kinetic energy and pressure.

[0044] like Figure 3 As shown, the diaphragm assembly 300 includes a connecting portion 310 and multiple diaphragm bodies 320, with the multiple diaphragm bodies 320 respectively disposed on the connecting portion 310. The connecting portion 310 is located between the storage portion 110 and the coupling portion 120, and the multiple diaphragm bodies 320 are respectively disposed corresponding to the chambers 130. The diaphragm assembly 300 adopts a design that integrates multiple independent diaphragm bodies 320 in the connecting portion 310. By fixing the connecting portion 310 between the storage portion 110 and the coupling portion 120, and ensuring that each diaphragm body 320 is precisely arranged to correspond to the chambers 130, both synchronous sealing and controllable isolation of multiple chambers 130 are achieved, and the consistency of directional opening of each channel when gas breaks through the diaphragm is ensured.

[0045] like Figure 3 As shown, the thickness of the diaphragm body 320 is less than the thickness of the connecting portion 310. This differentiated design, where the diaphragm body 320 is thinner than the connecting portion 310, achieves a balance between function and strength through structural optimization: the thinner diaphragm body 320 allows for precise control of the rupture pressure threshold, ensuring rapid and reliable opening under a preset pressure, reducing energy loss and response delay; while the thicker connecting portion 310 provides higher mechanical strength, capable of withstanding the assembly stress and working load between the storage portion 110 and the coupling portion 120, maintaining overall structural stability. Furthermore, the thickness gradient design guides stress concentration in the diaphragm body 320 area, preventing accidental deformation or damage to the connecting portion 310. Simultaneously, the thickness transition ensures controllability of the diaphragm rupture path, guaranteeing both the tightness of the sealing phase and the integrity and consistency of the channel opening after rupture, improving system durability and operational accuracy.
