Description
Technical Field
[0001] This invention belongs to the technical field of marine rocket launch equipment, specifically a marine rocket launch device with a buffer structure. Background Technology
[0002] Rocket launches at sea are usually carried out on launch platforms that need to have good stability and adaptability to cope with the complex and ever-changing marine environment.
[0003] During rocket launch, propellant combustion and high-speed gas injection generate a large amount of high-temperature gas flow at the rocket's tail. To prevent this high-temperature gas flow from damaging equipment on the launch platform, a flow-blocking mechanism is typically constructed. For example, a marine rocket launcher is disclosed in the relevant technology (application number CN2024116990664). In this design, a flow-blocking device fixedly connected to the hull of the launcher blocks and diverts the lateral hot jet generated by the longitudinal guide channel during rocket launch, thereby reducing thermal damage to aerospace control equipment caused by the lateral hot jet generated during rocket launch and improving the service life of the rocket launcher.
[0004] However, in practical applications, it has been found that, on the one hand, due to the strong airflow impact force generated during rocket launch, although the completely fixed flow-blocking device has a good blocking effect on the airflow, it is easy to deform under the strong airflow impact. After use, it is inconvenient to disassemble and store the flow-blocking device. On the other hand, due to the high temperature of the tail airflow generated by rocket launch, the combination of high temperature and airflow impact further increases the probability of deformation and damage to the flow-blocking device.
[0005] In view of this, the present invention proposes a rocket sea launch device with a buffer structure to solve the above-mentioned technical problems. Summary of the Invention

Buffer springs are fixedly installed inside the buffer cylinders. The connecting frame is mounted on the baffle plate, and the end of the connecting frame away from the baffle plate extends into the buffer cylinder and is fixedly connected to the buffer spring.

[0011] Preferably, a guide plate is installed above the flow-blocking plate, the guide plate has an arc-shaped design, and the guide plate extends in the direction of the longitudinal flow channel.
[0012] Preferably, a water-drawing tank is embedded in the side of the flow-blocking plate near the connecting frame, the flow-guiding plate extends above the water-drawing tank, and a piston plate is fixedly installed at the bottom end of the flow-guiding plate by a guide rod. The piston plate extends into the interior of the water-drawing tank, and the water-drawing tank is connected to seawater through a negative pressure pipe.
[0013] Preferably, the guide plate, guide rod, and piston plate are all provided with an overflow groove, and a one-way valve is installed in both the overflow groove and the negative pressure pipe.

[0016] Preferably, an elastic bracket is installed at an angle at the top of the limiting tube, and the elastic bracket is located on the rotation path of the guide rod.
[0017] The beneficial effects of this invention are as follows: 1. The rocket sea launch device with a buffer structure described in this invention, by setting up a buffer guiding mechanism, on the one hand, during the exhaust gas burst process, through the compression of the buffer spring and the directional flow of seawater, continuously consumes the impact force of the exhaust gas on the baffle plate. Compared with a fixed baffle plate, it can effectively disperse the impact force, thereby reducing the probability of the baffle plate being damaged during the impact. At the same time, the seawater flows under the action of the impact force and eventually flows to the surface of the baffle plate.

After the airflow burst ends, the overflow is used to cool down the deflector plate and the deflector plate, further reducing the probability of damage to the deflector plate.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0022] like Figures 1 to 7 As shown, the present invention provides a rocket sea launch device with a buffer structure, including a launch platform 1 and a baffle plate 11. The launch platform 1 provides a place for rocket sea launch, and the baffle plate 11 is installed on the launch platform 1. The baffle plate 11 is used to obstruct the flow of rocket exhaust gas. It also includes a buffer guide mechanism, which is installed on the launch platform 1 and is used to cooperate with the baffle plate 11 to achieve buffered flow obstruction of the airflow; The buffer guiding mechanism includes a buffer cylinder 2, a connecting frame 22, and a guide plate 3; The launch platform 1 is provided with a longitudinal drainage channel 12. Each longitudinal drainage channel 12 is fixedly installed with a buffer cylinder 2 on the side away from each other. A buffer spring 21 is fixedly installed inside the buffer cylinder 2. The connecting frame 22 is mounted on the baffle plate 11, and the end of the connecting frame 22 away from the baffle plate 11 extends into the buffer cylinder 2 and is fixedly connected to the buffer spring 21.
[0023] The connecting frame 22 is located inside the buffer cylinder 2 and a sealing plate 23 is fixedly installed at one end. A water outlet pipe 24 is fixedly installed on the sealing plate 23. A water pumping pipe 25 is installed on the buffer cylinder 2. Both the water outlet pipe 24 and the water pumping pipe 25 are unidirectional pipes. The water outlet pipe 24 extends to the top of the flow-blocking plate 11.
[0024] When the rocket is launched at sea, the presence of the baffle plate 11 and the longitudinal diversion groove 12 is used to block and divert the high temperature and high pressure exhaust gas generated by the launch, thereby reducing the damage of the exhaust gas to the instruments on the launch platform 1. At the same time, a buffer guiding mechanism is also provided in this invention to reduce the damage of the high temperature and high pressure airflow to the baffle plate 11 and maintain the baffle plate 11's obstruction effect.
[0025] Specifically, during the preparation process before rocket launch, staff manually inject seawater into the buffer cylinder 2 through pre-reserved water injection holes, and close the water injection holes after filling with seawater. When the rocket launches, the high-temperature, high-pressure exhaust gas erupts from the rocket's tail, impacting the baffle plate 11. This causes the baffle plate 11 to push the connecting frame 22 and the sealing plate 23. As the sealing plate 23 continues to move within the buffer cylinder 2, the buffer springs 21 within the buffer cylinder 2 are compressed. Simultaneously, the seawater within the buffer cylinder 2, under pressure, flows out through the outlet pipe 24 to the top of the baffle plate 11. During this process, the compression of the buffer springs 21 and the flow of seawater are both powered by the impact force of the airflow, thus effectively reducing damage to the baffle plate 11 from the airflow impact. Furthermore, due to the arrangement of the longitudinal drainage channel 12 and the baffle plate 11, the explosion... The exhaust gas flow eventually flows along the longitudinal diversion channel 12. During this process, the seawater flowing down from the top of the baffle plate 11 is pushed by the airflow and diffuses on the baffle plate 11. During the diffusion process, the seawater continuously absorbs heat until it evaporates into water vapor and is carried into the sea by the airflow. The continuous pumping and evaporation of seawater achieves continuous cooling of the baffle plate 11, thereby delaying the heating effect of the exhaust gas flow on the baffle plate 11. At the same time, it can also reduce the final temperature peak reached by the baffle plate 11 in a single flow blocking operation. When the airflow bursts, the compressed buffer spring 21 returns to its original state and pushes the baffle plate 11 to return to its original state. During this process, the sealing plate 23 moves continuously, thereby creating a negative pressure inside the buffer cylinder 2. With the cooperation of the water pumping pipe 25, the seawater is drawn back into the buffer cylinder 2, thus facilitating the next flow blocking operation.
[0026] This invention, by setting up a buffer guiding mechanism, continuously consumes the impact force of the exhaust gas on the baffle plate 11 during the exhaust gas burst process through the compression of the buffer spring 21 and the directional flow of seawater. Compared with the fixed state of the baffle plate 11, it can effectively disperse the impact force, thereby reducing the probability of the baffle plate 11 being damaged during the impact. At the same time, the seawater flows under the action of the impact force and eventually flows to the surface of the baffle plate 11. The evaporation of seawater absorbs heat, delaying the heating effect of the exhaust gas on the baffle plate 11, reducing the final temperature peak of the baffle plate 11, further reducing the probability of the baffle plate 11 being damaged, and extending the service life of the baffle plate 11.
[0027] In a preferred embodiment of the present invention, a dispersion tube 26 is embedded in the flow baffle 11, the water outlet pipe 24 is connected to the dispersion tube 26, and a uniformly distributed flow groove 27 is formed on the flow baffle 11. The flow groove 27 is connected to the dispersion tube 26, and the cross-section of the flow groove 27 is triangular, with a horizontal bottom and an inclined side.
[0028] The dispersion tube 26 is installed vertically, and the flow channels 27 are all arranged parallel to the longitudinal diversion channels 12.
[0029] To further enhance the effect of seawater evaporation and heat absorption on the baffle plate 11, in practical applications, a dispersion tube 26 is embedded in the baffle plate 11. A rubber plug with a central opening is embedded at the alignment of the dispersion tube 26 with the flow channel 27. The flow channel 27 is horizontally arranged along the height direction of the baffle plate 11. Therefore, when seawater in the buffer cylinder 2 flows into the dispersion tube 26 through the outlet pipe 24, as the dispersion tube 26 is gradually filled, the pressure inside the dispersion tube 26 increases. Under the action of pressure, the seawater flows into the flow channel 27 and flows horizontally along the flow channel 27. During this process, the exhaust gas flows along the longitudinal guide channel 12. During the flow of the exhaust gas, it pushes the seawater to flow in the flow channel 27. The seawater evaporates and absorbs heat during the movement, thereby reducing the heating effect of the exhaust gas on the baffle plate 11.
[0030] In a preferred embodiment of the present invention, a guide plate 3 is installed above the flow-blocking plate 11. The guide plate 3 has an arc-shaped design and extends in the direction of the longitudinal flow channel 12.
[0031] The flow-blocking plate 11 is embedded with a water tank 4 near the connecting frame 22. The flow-guiding plate 3 extends above the water tank 4, and a piston plate 42 is fixedly installed at the bottom of the flow-guiding plate 3 through a guide rod 41. The piston plate 42 extends into the water tank 4, and the water tank 4 is connected to seawater through a negative pressure pipe 43.
[0032] The guide plate 3, guide rod 41, and piston plate 42 are all provided with an overflow groove 5. One-way valves are installed in both the overflow groove 5 and the negative pressure pipe 43.
[0033] The top of the flow deflector 11 is inclined, and a sealing pad 51 is fixedly installed on the side of the flow deflector 11 near the flow guide plate 3.
[0034] Due to the exhaust gas from the explosion, most of it flows along the longitudinal diversion channel 12, while a small portion flows upwards, carrying water vapor along the way. To reduce the probability of the water vapor falling over the baffle plate 11, a guide plate 3 is provided above the baffle plate 11 in this invention. The guide plate 3 has an arc-shaped design, so when the airflow moves upwards along the baffle plate 11, it is obstructed and guided by the guide plate 3, causing the airflow to flow towards the baffle plate 11. At the same time, the impact force exerted by the airflow on the guide plate 3 also causes the guide plate 3 to tend to move upwards. When the guide plate 3 pulls the guide rod 41 and the piston plate 42 upwards, a negative pressure is generated at the bottom of the water tank 4, which in turn causes the negative pressure pipe 43 to draw seawater into the water tank 4. As the water level in the water tank 4 gradually rises, it is in a state of continuous heating. In its current state, the baffle plate 11 exchanges heat with seawater, further slowing down the rate of temperature rise of the baffle plate 11 and reducing the final temperature peak reached by the baffle plate 11. After the exhaust gas bursts out (at this time, the buffer spring 21 in the buffer cylinder 2 begins to reset and the water outlet pipe 24 stops discharging water), under the gravity of the piston plate 42, guide rod 41 and baffle plate 3, the baffle plate 3 and piston plate 42 tend to move downwards and reset. During this process, the seawater in the pumping tank 4 enters the overflow trough 5 under the pressure of the baffle plate 3 and piston plate 42, and overflows from the top of the baffle plate 3. The overflowing seawater flows down along the surface of the baffle plate 3 and finally flows into the surface of the baffle plate 11 with the cooperation of the sealing pad 51, thereby cooling the baffle plate 3 and baffle plate 11.
[0035] This invention guides the airflow by setting a guide plate 3 and applies an impact force to the guide plate 3 through the airflow to extract seawater from the pumping tank 4. During the airflow burst, the total specific heat capacity of the pumping tank 4 and the baffle plate 11 is increased by increasing the volume of seawater in the pumping tank 4, thereby reducing the heating rate of the baffle plate 11. After the airflow burst ends, the overflow is used to cool down the guide plate 3 and the baffle plate 11, further reducing the probability of damage to the baffle plate 11.
[0036] In a preferred embodiment of the present invention, a limiting tube 52 is fixedly installed on the water tank 4. The limiting tube 52 is open at both ends. The guide rod 41 is slidably installed inside the limiting tube 52. The guide rod 41 is hinged to the piston plate 42. When the piston plate 42 rises to the top of the water tank 4, the guide rod 41 disengages from the limiting tube 52.
[0037] An elastic bracket 53 is installed at an angle at the top of the limiting tube 52, and the elastic bracket 53 is located on the rotation path of the guide rod 41.
[0038] To reduce the probability of deformation of the guide plate 3 after it rises to its limit, in this invention, under the impact of airflow, the guide plate 3 pulls the guide rod 41 upward. As the guide rod 41 continues to rise, it eventually disengages from the limiting tube 52 and deflects away from the airflow under the impact of airflow, eventually being intercepted by the elastic bracket 53. At this time, since the guide plate 3 is in an inclined state compared to the flow-blocking plate 11, the guide plate 3 is less affected by the airflow. After the airflow burst ends, under the gravity pull of the piston plate 42, the guide rod 41 deflects again, causing the guide plate 3 to press tightly against the sealing pad 51. During the continuous descent, seawater continuously overflows from the overflow trough 5.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
