Abstract
Description
Technical Field
[0001] The present invention relates to the field of aerospace technology, and particularly relates to an outlet arrangement structure of the gas supply pipeline of a three-level launch pad. Background Art
[0002] In the aerospace field, the superiority of the three-level launch pad lies in that it simplifies the launch process and reduces the facility complexity. Since the horizontal state testing and transportation are adopted, the launch pad does not need to be equipped with a tall service tower, which not only reduces the construction cost, but also improves the flexibility and maintainability of the system. However, this mode also brings challenges to the layout of the gas supply pipeline.
[0003] For the existing three-level launch pad, the gas supply pipeline extends vertically upward from the inside of the launch pad and is protected by a cover coated with fireproof cement. However, due to the high speed and temperature of the rocket jet flow, it is easy to wash away the fireproof cement, resulting in local overheating or ablation, and there is a risk of burning out the gas supply pipeline; at the same time, it will affect the airflow field around the launch pad, affecting the stability of the rocket and also easily causing damage to the launch pad itself.
[0004] Therefore, how to optimize the outlet arrangement of the gas supply pipeline is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention
[0005] The purpose of the present invention is to provide an outlet arrangement structure of the gas supply pipeline of a three-level launch pad, which can make the ground-to-rocket interface of the gas supply pipeline close to the rocket while avoiding being affected by the high-temperature and high-speed hot jet flow of the rocket.
[0006] To achieve the above purpose, the present invention provides the following technical solutions:
[0007] An outlet arrangement structure of the gas supply pipeline of a three-level launch pad, comprising: a fixed launch pad, a protective cover and a protection plate. The side of the fixed launch pad is provided with a ground-to-rocket interface for the gas supply pipeline to extend out. One side of the protective cover is connected to the side part of the fixed launch pad. The ground-to-rocket interface is communicated with the inner cavity of the protective cover. The side part of the protective cover is provided with a hose interface. One side of the protection plate is connected to the fixed launch pad and is located above the protective cover.
[0008] In some embodiments, the upper surface of the protection plate is inclined, and the height of the side of the upper surface of the protection plate close to the fixed launch pad is higher than the height of the side of the upper surface of the protection plate far from the fixed launch pad.
[0009] In some embodiments, the projection of the protective cover in the top view direction is within the projection range of the protection plate in the top view direction.
[0010] In some embodiments, the hose interface is located on the side plate of the protective cover adjacent to the gas supply rocket-ground interface.
[0011] In some embodiments, a plurality of the gas supply rocket-ground interfaces are provided on the side of the fixed launch pad, and a plurality of the hose interfaces are respectively provided on the opposite sides of the protective cover.
[0012] In some embodiments, the plurality of gas supply rocket-ground interfaces and the plurality of hose interfaces are respectively distributed in a rectangular array.
[0013] In some embodiments, the gas supply pipeline outlet arrangement structure of the three-flat launch pad further includes a hose plugging member, which is used to plug the hose interface when no hose is connected.
[0014] In some embodiments, the gas supply pipeline outlet arrangement structure of the three-flat launch pad further includes a hose plugging plate, and a plurality of the hose plugging members are provided on the hose plugging plate.
[0015] In some embodiments, the protective cover is detachably connected to the fixed launch pad.
[0016] In some embodiments, the protective plate is detachably connected to the fixed launch pad.
[0017] Compared with the prior art, the above technical solution has the following advantages:
[0018] A gas supply pipeline outlet arrangement structure of a three-flat launch pad provided by the present invention includes: a fixed launch pad, a protective cover and a protective plate. A gas supply rocket-ground interface for the gas supply pipeline to extend out is provided on the side of the fixed launch pad. One side of the protective cover is connected to the side part of the fixed launch pad, wherein the gas supply rocket-ground interface is communicated with the inner cavity of the protective cover, and a hose interface is provided on the side part of the protective cover. One side of the protective plate is connected to the fixed launch pad and is located above the protective cover. Since the gas supply pipeline extends out from the side part of the fixed launch pad to be as close to the rocket as possible, its position will not affect the operation of other devices, and the protective cover can play a protective role. In addition, a protective plate is provided above the protective cover. When performing a launch mission, if the influence range of the heat flow is too large, the protective plate can play a certain role in guiding the flow to prevent the heat flow from directly scouring the protective cover. In addition, in daily life, the protective plate can also play a role in rain protection, dust protection and preventing heavy objects from falling, so as to play a protective role.

[0025] Please refer to Figure 1 and Figure 2 .
[0026] A structure for arranging the outlet of the gas supply pipeline of a three - flat launch pad provided by an embodiment of the present invention includes: a fixed launch pad 20, a protective cover 30, and a protective plate 40. There is a movable launch pad 10 on the fixed launch pad 20. One side below the fixed launch pad 20 has an underground pipe gallery 60. After the gas supply pipeline 50 is led out from the underground pipe gallery 60, it extends upward into the fixed launch pad 20. There is a gas supply rocket - ground interface 21 on the side of the fixed launch pad 20 for the gas supply pipeline 50 to extend out. One side of the protective cover 30 is connected to the side of the fixed launch pad 20. For example, it can be connected by a fixed method such as welding together, or it can be detachably connected, such as connected by bolts. Among them, the gas supply rocket - ground interface 21 communicates with the inner cavity of the protective cover 30. There is a hose interface 31 on the side of the protective cover 30. The hose interface 31 is used for the rocket hose to pass through. The rocket hose is connected to the gas supply pipeline 50 extending into the protective cover 30. One side of the protective plate 40 is connected to the fixed launch pad 20 and is located above the protective cover 30. The protective plate 40 can be connected by a detachable connection method. When the protective plate 40 is damaged, the protective plate 40 can be replaced to reduce the maintenance cost. Since the gas supply pipeline 50 extends out from the side of the fixed launch pad 20 as close as possible to the rocket, its position will not affect the operation of other equipment, and the protective cover 30 can play a protective role. In addition, there is a protective plate 40 above the protective cover 30. During the launch mission, if the influence range of the heat flow is too large, the protective plate 40 can play a certain role in guiding the flow, preventing the heat flow from directly scouring the protective cover 30. In addition, in daily life, the protective plate 40 can also play a role in preventing rain, dust, and falling heavy objects to play a protective role.
[0027] In some embodiments, as Figure 1 and Figure 2 shown, the upper surface of the protective plate 40 is inclined, that is, the upper surface of the protective plate 40 is an inclined plane, and the height of the side of the upper surface of the protective plate 40 close to the fixed launch pad 20 is higher than the height of the side of the upper surface of the protective plate 40 far from the fixed launch pad 20, that is, the outer edge of the protective plate 40 slopes downward, which can play a role in guiding the flow.
[0028] In some embodiments, as Figure 2 shown, the projection of the protective cover 30 in the top - view direction is within the projection range of the protective plate 40 in the top - view direction, that is, the outer contour of the protective plate 40 in the top - view direction is larger than the outer contour of the protective cover 30 in the top - view direction to fully protect the protective cover 30.
[0029] In some embodiments, the hose interface 31 is located on the side plate of the protective cover 30 adjacent to the gas supply rocket - ground interface 21. For example Figure 2 shown, the hose interface 31 is located on the left and right sides of the protective cover 30, and the hose can be connected through the side of the protective cover 30.
[0030] In some embodiments, a plurality of gas supply rocket-ground interfaces 21 are provided on the side surface of the fixed launch pad 20, and a plurality of hose interfaces 31 are respectively provided on the opposite sides of the protective cover 30. For example Figure 2 As shown, a plurality of hose interfaces 31 can be respectively provided on the left side and the right side of the protective cover 30. In some embodiments, the plurality of gas supply rocket-ground interfaces 21 and the plurality of hose interfaces 31 are respectively distributed in a rectangular array. When the side plate of the protective cover is rectangular, it is preferably distributed in a rectangular array. In addition to the rectangular array distribution, other uniform distribution methods or non-uniform distribution methods can also be adopted, and specific selection can be made according to actual needs.
[0031] In some embodiments, the outlet arrangement structure of the three-level horizontal launch pad gas supply pipeline further includes a hose plugging member, which is used to plug the hose interface 31 when no hose is connected, for example, when there is no launch mission, so as to prevent foreign objects from entering the protective cover. Further, the outlet arrangement structure of the three-level horizontal launch pad gas supply pipeline 50 further includes a hose plugging plate, and a plurality of hose plugging members are provided on the hose plugging plate. For example, when a plurality of hose interfaces 31 distributed in a rectangular array are provided on the protective cover, a plurality of hose plugging members distributed in a rectangular array can be provided on the hose plugging plate, so as to facilitate plugging a plurality of hose joints in one operation, thereby improving the operation convenience and work efficiency.
[0032] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other.
[0033] The above has introduced in detail an outlet arrangement structure of a three-level horizontal launch pad gas supply pipeline provided by the present invention. Specific examples are used herein to elaborate the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the core idea of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
