Description

Technical Field

[0001] This invention belongs to the field of marine rocket launch technology, specifically a marine rocket launch platform equipped with a rocket body stabilization structure. Background Technology

[0002] A sea-based rocket launch platform is a special engineering vessel or floating structure used for launching carrier rockets at sea. It possesses a full range of functions, including rocket storage, assembly, testing, fueling, and launch. Compared to land-based launch sites, its core advantage is its high mobility, allowing launches from low-latitude sea areas near the equator.

[0003] Chinese patent application CN202410077117.3 discloses a sea-based rocket launcher. The key technical features of the application are: a launch hull with multiple aerospace control devices distributed on it; a launch pad fixedly connected to the launch hull; longitudinal guide channels on both sides of the launch pad; a rocket to be launched mounted on the launch pad; and a flow-blocking device fixedly connected to the launch hull. The flow-blocking device includes a flow-blocking plate and at least two supporting structures. The flow-blocking plate is mounted on the launch hull and fixedly connected to the launch hull on one side.

[0004] However, in practical applications, it has been found that when using launch ships to transport rockets, the launch ships are affected by wind and waves and sway to a certain extent, which makes the rocket less stable on the ship. Therefore, how to ensure the stable transport of rockets on the ship has become the technical problem to be solved by this invention. In view of this, this invention proposes a marine rocket launch platform with a rocket body stabilization structure to solve the above-mentioned technical problem. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The marine rocket launch platform with a rocket body stabilization structure of the present invention includes a hull; a base for mounting the rocket is provided on the hull; a set of fixing rings is provided on the hull, and a set of annularly distributed first hydraulic rods are fixedly connected to the inner wall of the fixing rings; a stabilizing block is fixedly connected to the output end of the first hydraulic rods, and the stabilizing block is used to stabilize the rocket.

[0007] A set of connecting rods is provided on the hull, and a set of fixed rings are distributed on the connecting rods and slidably connected to the connecting rods. A moving component is provided on the connecting rods to allow the fixed rings to move.

[0008] The moving component includes a motor fixed to the top surface of the connecting rod, a take-up reel fixedly connected to the output end of the motor, a first steel cable fixedly connected to the surface of the take-up reel, the end of the first steel cable away from the take-up reel being fixedly connected to the uppermost fixed ring, and a set of second steel cables fixedly connected between a set of fixed rings.

[0009] The connecting rod has a first cavity inside, and the outer wall of the connecting rod has multiple sets of symmetrically arranged through grooves. The through grooves are connected to the first cavity, and a positioning block is slidably connected in the through groove. The arrow body is provided with a control component to control the movement of the positioning block.

[0010] The control component includes a hollow groove formed in a connecting ring, a push ring slidably connected in a sealed manner in the hollow groove, a second hydraulic rod fixedly connected to the top surface of the connecting ring, the output end of the second hydraulic rod extending into the hollow groove and fixedly connected to the push ring, the first cavity communicating with the hollow, and a spring fixedly connected to one side of the positioning blocks that are close to each other.

[0011] The stabilizing block is arc-shaped, and an elastic plate is fixedly connected to the side of the stabilizing block away from the first hydraulic rod.

[0012] The fixing ring has a set of second cavities, and a connecting pipe is connected to the second cavity. The elastic plate has a hollow structure inside. The end of the connecting pipe away from the second cavity is connected to the inside of the elastic plate. The fixing ring has a first connecting groove that communicates with the second cavity. The connecting rod has a second connecting groove that corresponds to the first connecting groove. The second connecting groove communicates with the first cavity.

[0013] A circular groove is provided inside the fixed ring, and a rotating wheel is rotatably connected inside the circular groove. The outer wall of the rotating wheel is in contact with the connecting rod.

[0014] The beneficial effects of this invention are as follows: 1. This invention involves installing a rocket onto a base, where the rocket is positioned at the center of a fixing ring. When the ship is in motion at sea, the first hydraulic rod is activated, causing its output end to push a stabilizing block. This causes the stabilizing block to move closer to the rocket body, making contact with the rocket body and thus stabilizing it, thereby improving the stability of the rocket during transportation.

[0015] 2. This invention utilizes a motor to drive a take-up reel, which in turn winds a first steel cable around the reel. This first steel cable pulls the fixed rings upwards, and the uppermost fixed ring, in turn, is pulled upwards by a second steel cable, causing the other fixed rings to move synchronously upwards. The arrow body is then stabilized by a stabilizing block. When routine maintenance of the first hydraulic rod is required, the motor output is reversed, causing the first steel cable to descend. This causes all the fixed rings to move downwards synchronously until they reach their lowest point, facilitating maintenance of the first hydraulic rod. Attached Figure Description

[0019] 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.

[0020] Example 1: As Figures 1 to 4 As shown in the figure, the marine rocket launch platform with a rocket body stabilization structure according to the embodiment of the present invention includes a hull 1; a base 2 for mounting the rocket is provided on the hull 1; a set of fixing rings 3 are provided on the hull 1, and a set of annularly distributed first hydraulic rods 6 are fixedly connected to the inner wall of the fixing rings 3; a stabilizing block 7 is fixedly connected to the output end of the first hydraulic rod 6, and the stabilizing block 7 is used to stabilize the rocket. By installing the rocket onto the base 2, the rocket will be located at the center of the fixing ring 3. When the ship 1 is running at sea, the first hydraulic rod 6 is activated, and the output end of the first hydraulic rod 6 pushes the stabilizing block 7. At this time, the stabilizing block 7 will move closer to the rocket body and come into contact with the rocket body, thereby stabilizing the rocket body and improving the stability of the rocket during transportation.

[0021] A set of connecting rods 4 is provided on the hull 1, and a set of fixed rings 3 are distributed on the connecting rods 4 and slidably connected to the connecting rods 4. The connecting rods 4 are provided with a moving component that allows the fixed rings 3 to move. The first hydraulic rod 6 used in this application requires daily maintenance. It is inconvenient to perform daily maintenance when it is set at a high position. With the above mechanism, the fixed rings 3 can be moved up and down on the connecting rods 4 with the help of the moving component. When maintenance is required, the fixed rings 3 can be moved down to the bottom of the hull 1, which makes it convenient for the staff to perform daily maintenance on the first hydraulic rod 6.

[0022] The moving component includes a motor 8 fixed to the top surface of the connecting rod 4. The output end of the motor 8 is fixedly connected to a take-up reel 9. A first steel cable 10 is fixedly connected to the surface of the take-up reel 9. The end of the first steel cable 10 away from the take-up reel 9 is fixedly connected to the uppermost fixed ring 3. A set of second steel cables 11 are fixedly connected between a set of fixed rings 3. When the arrow body needs to be stabilized, the motor 8 drives the take-up reel 9 to rotate. At this time, the first steel cable 10 will be wound around the take-up reel 9, thereby pulling the fixed ring 3 upward. The uppermost fixed ring 3 will be pulled upward by the second steel cable 11, and the other fixed rings 3 will move upward synchronously. Then, the fixed stabilizing block 7 is used to stabilize the arrow body. When the first hydraulic rod 6 needs to be maintained, the output end of the motor 8 is reversed. At this time, the first steel cable 10 will be lowered, thereby moving all the fixed rings 3 downward synchronously until they are lowered to the lowest point, so as to facilitate the maintenance of the first hydraulic rod 6.

[0023] The connecting rod 4 has a first cavity 19 inside, and the outer wall of the connecting rod 4 has multiple sets of symmetrically arranged through grooves. The through grooves are connected to the first cavity 19. A positioning block 12 is slidably connected in the through groove. The arrow body is provided with a control component to control the movement of the positioning block 12. After the fixed ring 3 in this application moves upward to a suitable position, the positioning block 12 is controlled by the control component to move away from the first cavity 19. At this time, the positioning block 12 will move below the fixed ring 3. At this time, the motor 8 can be turned off so that the positioning block 12 can position the fixed ring 3. When the fixed ring 3 needs to move downward, the fixed ring 3 is first pulled upward by the first steel cable 10, and then the positioning block 12 is moved into the first cavity 19 by the control component, so that the positioning block 12 is moved away from below the fixed ring 3. At this time, the fixed ring 3 can be lowered by the first steel cable 10.

[0024] The control component includes a hollow groove 15 formed in the connecting ring 5, a push ring 16 is slidably connected in the hollow groove 15, a second hydraulic rod 14 is fixedly connected to the top surface of the connecting ring 5, the output end of the second hydraulic rod 14 extends into the hollow groove 15 and is fixedly connected to the push ring 16, the first cavity 19 communicates with the hollow, and a spring 13 is fixedly connected to one side of the positioning blocks 12 that are close to each other. The push ring 16 is moved upward by controlling the output end of the second hydraulic rod 14. At this time, the push ring 16 will push the gas in the hollow groove 15 into the first cavity 19, so that the gas pushes the positioning block 12 to move the positioning block 12 below the fixed ring 3. The push ring 16 is moved downward by controlling the output end of the second hydraulic rod 14. At this time, the gas in the first cavity 19 will flow back into the hollow groove 15, so that the spring 13 pulls the positioning block 12 away from below the fixed ring 3.

[0025] The stabilizing block 7 is arc-shaped, and an elastic plate 21 is fixedly connected to the side of the stabilizing block 7 away from the first hydraulic rod 6. When the first hydraulic rod 6 pushes the stabilizing block 7 to stabilize the arrow body, the elastic plate 21 will contact the arrow body to avoid the stabilizing block 7 directly contacting the arrow body and causing unnecessary wear.

[0026] The fixing ring 3 has a set of second cavities 22, and a connecting pipe 20 is connected to the second cavity 22. The elastic plate 21 has a hollow structure. The end of the connecting pipe 20 away from the second cavity 22 is connected to the interior of the elastic plate 21. The fixing ring 3 has a first connecting groove 17 that communicates with the second cavity 22. The connecting rod 4 has a second connecting groove 18 that corresponds to the first connecting groove 17. The second connecting groove 18 communicates with the first cavity 19. When the fixing ring 3 in this application is pulled upward by the first steel cable 10, the first connecting groove 17 will connect with the second connecting groove 18. At this time, the positioning block 12 can be controlled to move away from the first cavity 19. After the positioning ring contacts the positioning block 12, the positioning block 12 will be pressed down by the gravity of the fixing ring 3. Then, before the elastic plate 21 contacts the arrow body, the push ring 16 can continue to move upward. At this time, the gas in the first cavity 19 will pass through the second connecting groove 18 and the first connecting groove 17, and finally enter the second cavity 22. At this time, the gas can enter the elastic plate 21 from the connecting pipe 20, thereby causing the elastic plate 21 to expand, so as to increase the contact area with the arrow body and thus improve the protection effect.

[0027] Example 2: Figures 5 to 6 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a circular groove 23 is provided in the fixed ring 3, and a rotating wheel 24 is rotatably connected in the circular groove 23. The outer side wall of the rotating wheel 24 contacts the connecting rod 4. When the fixed ring 3 moves upward in this application, the rotating wheel 24 will contact and rotate with the connecting rod 4 to reduce the friction between the fixed ring 3 and the connecting rod 4, thereby reducing the resistance to upward movement and reducing the load on the motor 8 during operation.

[0028] Working principle: By installing the rocket onto the base 2, the rocket will be located at the center of the fixing ring 3. When the ship 1 is in motion at sea, by activating the first hydraulic rod 6, the output end of the first hydraulic rod 6 pushes the stabilizing block 7. At this time, the stabilizing block 7 will move closer to the rocket body, and then contact the rocket body, thereby stabilizing the rocket body and improving the stability during rocket transportation. The first hydraulic rod 6 used in this application requires daily maintenance. Its high position makes daily maintenance inconvenient. The above mechanism allows the fixing ring 3 to move up and down on the connecting rod 4 with the help of the moving component. When maintenance is required, the fixing ring 3 can be moved down to the bottom of the ship 1. At this point, it is convenient for staff to perform routine maintenance on the first hydraulic rod 6. When it is necessary to stabilize the arrow body, the motor 8 drives the take-up reel 9 to rotate. At this time, the first steel cable 10 will be wound around the take-up reel 9, so that the first steel cable 10 pulls the fixed ring 3 upward. The uppermost fixed ring 3 will pull the other fixed rings 3 upward synchronously with the help of the second steel cable 11. Then, the arrow body is stabilized with the help of the fixed stabilizing block 7. When it is necessary to perform routine maintenance on the first hydraulic rod 6, the output end of the motor 8 is reversed. At this time, the first steel cable 10 will be lowered, so that all the fixed rings 3 move downward synchronously until they are lowered to the lowest point, so as to facilitate the maintenance of the first hydraulic rod 6. In this application, after the fixed ring 3 moves upward to a suitable position, the positioning block 12 is controlled by the control component to move away from the first cavity 19. At this time, the positioning block 12 will move below the fixed ring 3. The motor 8 can then be turned off, allowing the positioning block 12 to position the fixed ring 3. When the fixed ring 3 needs to move downward, the first steel cable 10 first pulls the fixed ring 3 upward, and then the control component moves the positioning block 12 into the first cavity 19, thereby removing the positioning block 12 from below the fixed ring 3. The fixing ring 3 can be lowered using the first steel cable 10; the push ring 16 is moved upward by controlling the output end of the second hydraulic rod 14. At this time, the push ring 16 will push the gas in the hollow groove 15 into the first cavity 19, thereby allowing the gas to push the positioning block 12 so that the positioning block 12 moves below the fixing ring 3. The push ring 16 is moved downward by controlling the output end of the second hydraulic rod 14. At this time, the gas in the first cavity 19 will flow back into the hollow groove 15, thereby allowing the spring 13 to pull the positioning block 12 away from below the fixing ring 3. In this application, when the first hydraulic rod 6 pushes the stabilizing block 7 to stabilize the arrow body, the elastic plate 21 will contact the arrow body, avoiding direct contact between the stabilizing block 7 and the arrow body, which would cause unnecessary wear. In this application, when the fixing ring 3 is pulled upward by the first steel cable 10, the first connecting groove 17 will connect with the second connecting groove 18. At this time, the positioning block 12 can be controlled to move away from the first cavity 19. After the positioning ring contacts the positioning block 12, the positioning block 12 will be pressed down by the weight of the fixing ring 3. Then, before the elastic plate 21 contacts the arrow body, the push ring 16 can continue to move upward. At this time, the gas in the first cavity 19 will pass through the second connecting groove 18 and the first connecting groove 17, and finally enter the second cavity 22. At this time, the gas can enter the elastic plate 21 from the connecting pipe 20, thereby causing the elastic plate 21 to expand, increasing the contact area with the arrow body and thus improving the protection effect.
