Description

Technical Field

[0001] This invention belongs to the field of rocket transportation and allocation devices, and in particular relates to a high-reliability satellite and rocket transportation and allocation device and method for a sea launch platform. Background Technology

[0002] Sea-based rocket launches offer advantages such as high flexibility and economic efficiency, allowing for flexible selection of launch points and landing zones to meet the launch requirements of various orbital payloads.

[0003] To further improve launch efficiency and achieve the goal of multiple launches within a single flight, it is urgent to overcome the technical challenge of rapid deployment and safe transport of satellites and rockets within the limited space of the launch platform. However, currently operational sea-based launch and transport systems suffer from insufficient sealing, low structural impact resistance, and poor fire resistance. Simultaneously, rockets face challenges such as low freedom of movement and low operational efficiency during land-sea transport. These issues, to some extent, affect the mission safety and equipment reliability of sea-based launches and hinder the development of mass sea-based rocket launches. Summary of the Invention

[0004] In view of this, the present invention aims to propose a highly reliable satellite-rocket transportation and allocation device and method for a sea launch platform, so as to solve the problems of low degree of freedom of movement and low operating efficiency in the land-sea transfer of rockets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-reliability satellite-rocket transportation and dispatching device for a maritime launch platform, comprising an upper transportation and maintenance section, a lower transportation and maintenance section, and a lower end transportation and maintenance section. Two lower transportation and maintenance sections are respectively located at the lower ends of the upper transportation and maintenance section. The lower end transportation and maintenance section is located below the middle section of the upper transportation and maintenance section. The upper transportation and maintenance section includes a seamlessly connected protective shell for the nose section of the rocket and a protective shell for the main body of the rocket. Both the nose section and the main body protective shell are independently opening and closing structures. The inner sides of the nose section and the main body protective shell are arranged along the axial direction... The rocket body is secured by multiple mechanical fixing rings. A movable slide rail is located directly below the main protective shell of the rocket tube along its long axis. The lower transport and maintenance section includes two longitudinal hydraulic lifting rods, a lateral telescopic device, and a main hydraulic device. The two longitudinal hydraulic lifting rods are located at both ends of the lateral telescopic device, which passes through the main hydraulic device. A first slide rail is provided on the main hydraulic device. The lower transport and maintenance section includes a mechanical rotating platform and a cross telescopic support. The bottom of the mechanical rotating platform is connected to the cross telescopic support. A second slide rail is provided on the mechanical rotating platform. The movable slide rail is connected to the first and second slide rails.

[0006] Furthermore, the upper part of the protective shell at the head of the quiver is in the shape of a conical trapezoidal dome, and the lower part is in the shape of a bowl. The main protective shell of the quiver is a hollow cylindrical structure with one end open and the other end closed. The protective shell at the head of the quiver can be opened 180° along one side axis, and the main protective shell of the quiver can be opened 90° along one side long axis. The moving slide rail is a long strip with stepped protrusions on the lower side.

[0007] Furthermore, a fire hydrant extinguishing system and a safety ladder are fixedly connected to both sides of the protective shell of the main body of the arrow tube, and the fire hydrant extinguishing system is equipped with portable fire extinguishing equipment.

[0008] Furthermore, the main body of the fire hydrant extinguishing system is a fire equipment fixing bracket, which is a fence-like structure composed of multiple rings, and the safety ladder is a special fire ladder.

[0009] Furthermore, the upper and lower parts of the protective shell at the head of the quiver and the protective shell on the main body of the quiver are connected on one side by a hinge, and the other side is equipped with a solenoid valve to control the opening and closing. The protective shell at the head of the quiver and the protective shell on the main body of the quiver are connected by a connecting buckle.

[0010] Furthermore, the mechanical fixing ring has a semi-circular cross-section and includes a mechanical claw and an annular fixing bracket. The annular fixing bracket is arranged along the axial direction inside the protective shell of the rocket's head and the protective shell of the rocket's main body. The annular fixing bracket is equipped with a mechanical claw, and the mechanical claw is equipped with mechanical fingers that grasp a pre-set fixing device on the rocket.

[0011] Furthermore, the longitudinal hydraulic lifting rod includes a lifting rod and a support base, the lifting rod and the support base being connected in cooperation; the lateral telescopic device includes a telescopic tube and a load-bearing tube, the telescopic tube and the load-bearing tube being connected in cooperation; the telescopic tube is capable of telescopic extension and rotation around its own central axis.

[0012] Furthermore, a rotating disk is provided below the mechanical rotating platform, and the rotating disk is connected to a cross telescopic support below.

[0013] Furthermore, the cross telescopic bracket includes a base, sliding guide rails, cross tie rods, and support rods. The two sliding guide rails are arranged parallel and symmetrically inside the base. One end of the cross tie rod is connected to the sliding guide rail by a sliding bolt, and the other end is connected to the rotating disk. The cross tie rods are cross-folded and connected to each other by connecting bolts. There are two support rods in total, which are inverted V-shaped structures. The bottom of the support rod is set on the base, and the top is connected to the rotating disk.

[0014] This invention also provides a method for the allocation of a high-reliability marine launch platform satellite-rocket transport and allocation device, specifically as follows: opening the protective shell of the rocket tube head and the protective shell of the rocket tube body, fixing the rocket to be transported between the various mechanical fixing rings, using mechanical claws to grip the rocket body, closing the shell through electromagnetic valve control, transporting the loaded rocket to the marine launch platform, aligning the moving slide rail with the groove built into the marine launch platform, using a rotating disk to align the rocket tail direction with the launch trajectory direction, and using a longitudinal hydraulic lifting rod to raise the main hydraulic device to drive the rocket tube to rise and align with the launch trajectory for loading.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The main functions of the present invention are as follows: (1) It provides an external integrated system for the sealing, cryogenic, collision protection, and fire protection requirements of satellite and rocket transportation. (2) It provides multi-degree-of-freedom support for the spatial transformation of satellite and rocket on the sea launch platform. Based on the above functions, the present invention can greatly improve the efficiency of satellite and rocket transportation and allocation during sea launch, reduce the risk of rocket damage, and has important supporting significance and development value for the commercial expansion of sea launch in my country.

[0016] This invention, by combining the basic transport protective shell with fire-fighting and maintenance equipment, significantly improves the overall protection efficiency of the transport device, making full use of the rocket tube protective shell and mechanical fixing ring to protect the rocket body. This enhances transport efficiency and has broad market and application prospects.

[0017] This invention employs a hydraulic lifting and sliding design, with a symmetrical design on the left, right, front, and back. While ensuring the rocket body operates in six degrees of freedom, it makes the overall structure more compact and reduces the size of the device. This allows for the arrangement of more auxiliary devices for the transport and deployment of satellites and rockets on the sea launch platform within a unit deck area, greatly improving protection and transport performance.
