Description
Technical Field
[0001] The invention relates to the field of ejection power devices, and in particular to a reusable, lightweight, and quickly disassembled high-pressure gas ejection device power unit and a use method thereof, as well as a high-pressure gas ejection device using the power unit. Background Art
[0002] Ejection power devices are widely used in both military and civilian fields. Currently, most ejection power devices use gas injection, which uses high-temperature gas as the ejection medium. During the ejection operation, the high-temperature gas continuously generated by the ejection power unit drives the ejection carrier to move and is eventually discharged into the surrounding environment. On the one hand, this type of ejection power unit has ablation on the inner wall of the launch device, which reduces the number of ejection reuses and increases the cost of use; on the other hand, it is easy to be detected, which to a certain extent weakens the battlefield survivability of the ejection equipment; and traditional ejection power units are generally made of metal materials, the product weight is large, and it is difficult to disassemble and install. Large auxiliary equipment or tooling is required, which is not suitable for occasions that require rapid response. Summary of the invention
[0003] The present invention provides a high-pressure gas ejection device power unit and a use method thereof, so as to at least solve the technical problems mentioned in the background technology.
[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: A power unit of a high-pressure gas ejection device comprises an air chamber, wherein the air chamber is provided with an air filling port and an air outlet; an air outlet screw cover is arranged outside the air outlet, and an air outlet through hole is arranged inside the air outlet screw cover to communicate with the air outlet; a threshold plate is arranged at the air outlet, wherein the threshold plate is a steel plate loaded with an ignition device and gunpowder, and the threshold plate separates the air outlet through hole from the air outlet; the air outlet through hole is a curved hole which forms a certain angle with the axial direction of the air outlet through hole.
[0005] The power unit of the present invention is provided with an air chamber for inflation, and uses the filled high-pressure gas as a power source to provide power to the ejection device. No high-temperature combustion gas is generated during the ejection process. Compared with the traditional ejection power device, it avoids continuous ablation of the inner wall of the launch device, significantly prolongs the service life of the ejection device, reduces the cost of use, and also reduces the possibility of being detected, thereby improving the survivability of the ejection equipment on the battlefield. A threshold plate loaded with an ignition device and gunpowder is provided at the air outlet. Only when a specific detonation signal is received will the steel plate be destroyed to allow the high-pressure gas to be ejected, and the power unit can be used continuously after the threshold plate is replaced, thereby reducing the cost of use. The air outlet through hole with a curved structure can redirect the direction of the airflow ejected from the air chamber, reduce the axial force when the product is excited, and reduce the structural strength requirements and assembly difficulty of the ejection device.
[0006] As a further preferred embodiment of the above technical solution, a groove is provided on the steel plate surface of the threshold plate, and the groove divides the middle area of the threshold plate into several parts, and the gunpowder is loaded in the groove. The gunpowder is installed in the groove. When the gunpowder is triggered, the high temperature generated causes the material performance at the groove to drop significantly or even fuse. Under the action of the internal pressure, the threshold plate cracks along the groove and bends outward to form a gas channel, which can avoid the threshold plate from being irregularly broken and causing the blockage of the gas outlet hole. The groove can be designed in different forms, such as a cross groove or a cross groove. The more grooves there are, the larger the area of the gas channel formed in the middle of the threshold plate in the later stage. Therefore, the power output of the gas unit can be controlled by controlling the groove form. At the same time, the groove depth, groove width and threshold plate material of the groove can be designed according to the internal pressure requirements. The threshold plate is made of materials with good toughness such as 304 stainless steel and 316 stainless steel, and the gunpowder is made of a blunt, high energy density heat-generating agent.
[0007] As a further preferred embodiment of the above technical solution, the end of the gas outlet hole is 90° with the axial direction of the gas outlet, and a rectifier is provided at the end of the gas outlet hole, one end of the rectifier is fixedly connected to the gas outlet hole, and the other end is a bell mouth, and a plurality of blades arranged around the axis of the rectifier are provided inside the rectifier. The rectifier can be matched with a threshold plate, and by selecting rectifiers of different structures and matching threshold plates with grooves of different shapes, the unstable airflow output through the gas channel of the threshold plate is further rectified, thereby ensuring the airflow stability of the gas output from the air chamber.
[0008] As a further preferred embodiment of the above technical solution, the intervals between adjacent blades are the same, and the twist angle of the blades is 15°~30°.
[0009] As a further optimization of the above technical solution, a flow rate sensor is installed at the end of the air outlet hole. By obtaining the flow rate data, the working state of the ejection power unit can be accurately grasped, providing a basis for the subsequent ejection operation adjustment, ensuring the safety and reliability of the ejection process, and ensuring that each ejection can achieve the expected effect.
[0010] As a further preferred embodiment of the above technical solution, the air chamber includes a metal liner and a composite material layer attached to the outer wall of the metal liner; the composite material layer is obtained by impregnating at least one of carbon fiber, glass fiber, basalt fiber and aramid fiber with resin and winding it with the metal liner as a core mold. The combination of composite materials and metal liner greatly reduces the weight of the power unit. On the one hand, it can reduce the requirements for the carrying capacity of the ejection device, and on the other hand, it can reduce the difficulty of assembling the power unit, so that the assembly can be completed by one person without the assistance of multiple people and tooling, and the installation and deployment can be completed quickly, which improves the application flexibility and practicality of the ejection power unit.
[0011] As a further preferred embodiment of the above technical solution, the resin includes one of epoxy resin, phenolic resin and vinyl resin.
[0012] As a further preferred embodiment of the above technical solution, an inflatable screw cover is provided outside the inflatable port, and an inflatable through hole is provided on the inflatable screw cover to connect the inflatable port; a sealing ring is provided between the air chamber and the inflatable screw cover, and between the air chamber and the threshold plate. This structure ensures the sealing of the air chamber, prevents leakage of high-pressure gas during filling and storage, ensures stable storage of high-pressure gas in the air chamber, and provides a reliable power source for ejection operations.
[0013] As a further preferred embodiment of the above technical solution, a large flange is installed outside the inflation port of the air chamber, and the large flange is provided with a plurality of threaded holes for connecting the ejection device, and a U-shaped hole is opened on the large flange. The threaded hole facilitates a stable connection with the ejection device, and the U-shaped hole reduces the weight of the flange, facilitates the holding of the flange and the installation of the power unit.
[0014] Based on the same technical concept, the present invention also provides a method for using the power unit of the high-pressure gas ejection device, comprising the following steps: S1. Before use, install the power unit of the high-pressure gas ejection device on the ejection device, connect the external inflation interface with the inflation port, and fill it with high-pressure gas; S2, sending a signal to the ignition device of the threshold plate to detonate the gunpowder to destroy the steel plate, so that the high-pressure gas is ejected from the gas chamber to provide ejection power to the ejection device; S3. After the excitation is completed, the threshold plate of the power unit of the high-pressure gas ejection device is replaced and reused.
[0015] The entire method of use is simple and convenient. After the excitation is completed, you only need to replace the threshold plate to reuse it. This not only reduces the cost of use, but also simplifies the operation process, improves the efficiency of the ejection power unit, and adapts to the needs of frequent use of the ejection device in different scenarios.
[0016] Based on the same technical concept, the present invention also provides a high-pressure gas ejection device, including a sealed initial volume chamber and a plurality of power units installed in the initial volume chamber for loading high-pressure gas, the initial volume chamber is provided with a gas outlet, and the gas volumes of the plurality of power units are different. The high-pressure gas is released through the power unit and output through the gas outlet of the initial volume chamber to provide ejection power for the high-pressure gas ejection device.
[0017] The high-pressure gas ejection device of the present invention uses the high-pressure gas in the power unit as the power source, and will not generate high-temperature combustion gas during the ejection process. Compared with the traditional ejection power device, it avoids the continuous ablation of the inner wall of the launch device, significantly prolongs the service life of the ejection device, reduces the use cost, and also reduces the possibility of being detected, thereby improving the survivability of the ejection equipment on the battlefield. At the same time, by using power units of different sizes in combination, different power units can be flexibly combined according to the preset ejection distance and speed requirements of the object to be ejected, thereby improving the use flexibility of the ejection device. Compared with the method of using a computer to control the opening and closing of the gas valve to adjust the power output, the mechanical structure of the present invention is more stable in use.
[0018] As a further preferred embodiment of the above technical solution, a large power unit and several small power units are installed in the primary chamber, the gas volume of the large power unit is larger than that of the small power units, the large power unit is installed in the middle of the primary chamber, and the small power units are evenly installed around the large power unit on the outside of the large power unit. This layout makes the high-pressure gas in the primary chamber relatively evenly distributed during release, thereby improving the stability and accuracy of the ejection and balancing the reaction force on the primary chamber.
[0019] As a further preferred embodiment of the above technical solution, the initial volume chamber includes an upper end plate, a cylinder wall and a lower end plate, which are enclosed to form a cylinder structure, and the upper end plate is provided with a gas outlet; a buffer chamber for bearing the pressure of the cylinder structure is provided below the cylinder structure, and the cylinder structure and the buffer chamber are enclosed to form a closed initial volume chamber. The setting of the buffer chamber can bear the pressure of the cylinder structure, avoid damage to the initial volume chamber due to excessive internal high-pressure gas pressure, and improve the safety and service life of the device.
[0020] As a further preferred embodiment of the above technical solution, an air bag is arranged in the buffer chamber, which further enhances the buffer effect, can better absorb and disperse the pressure transmitted from the initial volume chamber, protect the initial volume chamber structure, and also helps to maintain the overall stability of the device.
[0021] As a further preferred embodiment of the above technical solution, flanges are installed outside the gas charging ports of the power units, the large power unit is fixed to the lower end plate of the initial volume chamber through the flanges, and the small power unit is fixed to the flanges of the large power unit and the lower end plate of the initial volume chamber through the flanges. The installation of the flanges makes it easier to install and remove the power unit, and it is easy to replace the power unit after the excitation, so as to achieve the reuse of the high-pressure gas ejection device and reduce the use cost. The small power unit, the large power unit, and the initial volume chamber are connected through the flanges to form an integral structure, which improves the structural strength and stability.
[0022] As a further preferred embodiment of the above technical solution, the lower end plate is provided with a through hole at a position corresponding to the installation position of the power unit, so that the cylindrical structure and the buffer chamber are connected. The opening of the lower end plate is conducive to simplifying the installation of the power unit on the one hand, and the power unit can be directly pushed to the set position from the opening; on the other hand, it is also conducive to the conduction and dispersion of pressure. When under pressure, the airbag or other elastic material in the buffer chamber can contact the power unit from the opening, providing it with a better support effect and ensuring the stability of the entire primary chamber structure.
[0023] As a further preferred embodiment of the above technical solution, the cylinder wall includes an inner metal cylinder wall and a composite cylinder wall attached to the outside of the metal cylinder wall; the composite cylinder wall is obtained by impregnating at least one of carbon fiber, glass fiber, basalt fiber and aramid fiber with resin and winding it with the metal cylinder wall as a core mold. This structure not only utilizes the high strength and good sealing of the metal cylinder wall, but also combines the characteristics of light weight and high strength of the composite cylinder wall, reduces the overall weight of the device, and at the same time improves the compression resistance and corrosion resistance of the cylinder wall, thereby extending the service life of the device.
[0024] Compared with the prior art, the advantages of the present invention are: The power unit of the high-pressure gas ejection device of the present invention can effectively avoid ablation of the inner wall of the launch device, greatly extend the service life, reduce the cost of use, and can be reused by replacing the threshold plate after excitation, further saving costs. The non-continuous and non-high-temperature gas injection method reduces the possibility of being detected and improves battlefield survivability. At the same time, the stable sealing structure and flow rate monitoring function of the present invention ensure the safety and reliability of the ejection process, can monitor the working status in real time, and ensure that each ejection achieves the expected effect. In addition, the power unit of the present invention is light in weight, easy to disassemble and install, does not require large auxiliary equipment, and can be quickly deployed.
