Description

Technical Field

[0001] The invention relates to the technical field of rocket sea launch, and in particular to a rocket sea launch ship stabilization auxiliary device. Background Art

[0002] Sea-based rocket launch is an effective attempt to build a sea-based launch system by utilizing my country's abundant large ships, offshore platforms, port resources and mature solid rocket technology. It is an important supplement to my country's means of entering space after land-based launch sites. It enables flexible selection of launch points and landing areas, significantly improves carrying capacity, and effectively solves the problem of low-inclination launch capabilities.

[0003] Generally speaking, the sea launch platform can move over a large area at sea, and the ideal launch site is a low-latitude area near the equator. If the launch vehicle is launched near the equator, it can maximize the use of the earth's rotation speed, save propellant consumption, and thus increase the rocket's carrying capacity. This means that a launch vehicle of the same take-off size can have a higher carrying capacity when launched near the equator, and while the carrying efficiency is improved, the launch cost per unit mass of the payload can also be reduced.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1: Reference Figure 1-8 A rocket sea-launched ship stabilization auxiliary device is installed on both sides of a hull 1. Two telescopic rods 3 are provided on both sides of the hull 1. The output shafts of the two telescopic rods 3 on the same side are connected to the same auxiliary stabilization mechanism 4 through a lifting block 401. Both sides of the hull 1 are provided with mounting grooves 101. The telescopic rods 3 are fixed on the deck of the hull 1. The output shafts of the telescopic rods 3 pass through the deck of the hull 1 and are fixed to the auxiliary stabilization mechanism 4 located inside the mounting grooves 101. The auxiliary stabilization mechanism 4 includes a U-shaped mounting frame 402, the inner bottom end of which is rotatably connected to a buoyancy chamber 408 via a rotating shaft, and a telescopic rod 403 is installed between the buoyancy chamber 408 and the mounting frame 402 to drive the buoyancy chamber 408 to rotate around the rotating shaft, and storage grooves 4081 are provided on both sides of the buoyancy chamber 408, and a buoyancy inflatable airbag 407 that can be expanded outward is provided inside the storage groove 4081.

[0022] The storage groove 4081 is internally installed with a rodless telescopic rod 404, the output shaft of the rodless telescopic rod 404 is connected to a mounting column 405 which is slidably connected in the storage groove 4081, and the other end of the mounting column 405 is rotatably connected to a swing rod 4075 with an L-shaped cross-section, and a buoyancy inflatable airbag 407 is installed on the swing rod 4075 through an unfolding mechanism.

[0023] A rotating disk 4071 is installed at one end of the swing rod 4075, and a connecting shaft 4072 is installed at the edge of the rotating disk 4071. A downward extension is provided at one end of the mounting column 405, and a telescopic rod three 4073 is rotatably connected to the extension. The output shaft of the telescopic rod three 4073 drives the rotating disk 4071 to rotate through the connecting shaft 4072.

[0024] The deployment mechanism includes a fixed ring 4074 fixed to the vertical section of the swing rod 4075 and a sliding ring 4077 slidably sleeved on the vertical section of the swing rod 4075. A plurality of deployment rods 4079 are hinged on the outer wall of the fixed ring 4074. A transmission rod 4078 is hinged between the sliding ring 4077 and the corresponding deployment rod 4079. The buoyancy inflatable airbag 407 is installed on the deployment rod 4079. The buoyancy inflatable airbag 407 is connected to an air pump through an air guide tube, and the air pump is installed in the storage groove 4081. The vertical end of the swing rod 4075 is provided with a groove, in which a telescopic rod 4076 is embedded. The output shaft of the telescopic rod 4076 is connected to a sliding ring 4077. The movement of the output shaft of the telescopic rod 4076 can drive the sliding ring 4077 to slide up and down on the swing rod 4075. The sliding ring 4077 can drive the unfolding rod 4079 to fold and unfold through the transmission rod 4078, thereby realizing the folding and unfolding of the buoyancy inflatable airbag 407.

[0025] A sealing plate 406 is installed at one end of the mounting column 405, and the sealing plate 406 is slidably and sealingly connected to the opening of the storage groove 4081. When the auxiliary stabilizing mechanism 4 is not in use, the sealing plate 406 can make the interior of the storage groove 4081 in a sealed state, thereby reducing the corrosion damage to its internal parts by seawater.

[0026] When the stability of the rocket launch ship needs to be enhanced, the output shaft of the telescopic rod 1 3 drives the auxiliary stabilizing mechanism 4 to move out of the mounting groove 101 through the lifting block 401, and then the output shaft of the telescopic rod 2 403 drives the buoyancy chamber 408 to rotate a certain angle on the mounting frame 402, so that the buoyancy chamber 408 contacts the sea surface to generate buoyancy, and the output shaft of the rodless telescopic rod 404 drives the mounting column 405 and the components thereon to move out of the storage groove 4081, and the output shaft of the telescopic rod 3 4073 drives the rotating disk 4071 to rotate 90 degrees through the connecting shaft 4072, so that the swing rod 4075 is out of the water. The horizontal state is rotated to the vertical state, and the output shaft of the telescopic rod 4076 drives the sliding ring 4077 to slide upward on the swing rod 4075. The sliding ring 4077 drives the unfolding rod 4079 to unfold through the transmission rod 4078, thereby realizing the unfolding of the buoyancy inflatable airbag 407, and then the buoyancy inflatable airbag 407 is inflated through the inflation pump. After the buoyancy inflatable airbag 407 is inflated, buoyancy is generated to further enhance the stability of the hull. After the entire auxiliary stabilizing mechanism 4 is unfolded, the contact area with the sea surface is significantly improved compared with the original contact area of ​​the hull 1, thereby greatly improving the stability of the hull 1.

[0027] Embodiment 2, as Figure 1 , Figure 2 , Figure 4 As shown, what is different from Example 1 is that a counterweight block 2 is provided at the bottom end of the hull 1, and anchor chains 5 are fixedly connected to the four corners of the counterweight block 2. Pulleys are installed on both sides of the hull 1, and the other end of the anchor chain 5 passes through the corresponding pulley and is fixed to the lifting block 401, and a bottom groove 102 is opened at the bottom end of the hull 1, and the counterweight block 2 is movably embedded in the bottom groove 102, and sliding holes are opened on both sides of the installation groove 101, and pulleys are installed in the sliding holes, and the anchor chain 5 passes through the sliding holes and is slidably connected to the pulley.

[0028] After the lifting block 401 and the auxiliary stabilizing mechanism 4 are lifted up by the telescopic rod 3, the lifting of the lifting block 401 will drive the U-shaped anchor chain 5 to become a straight anchor chain 5, driving the position of the counterweight block 2 to drop, thereby lowering the center of gravity of the hull 1, allowing the hull to maintain better stability.

[0029] Embodiment 3, as Fig. 9 As shown, different from Example 2, the telescopic rod 1 3 and the auxiliary stabilizing mechanism 4 are directly installed on both sides of the hull 1, the counterweight block 2 is arranged at the bottom end of the hull 1, and the installation groove 101 and the bottom groove 102 are not arranged on both sides of the hull 1, and the pulley is also directly connected to both sides of the hull 1 through the rotating shaft; This arrangement makes it convenient to directly carry out transformation on the basis of the existing rocket launch ship without cutting and changing the hull 1, which reduces the transformation cost and enables the continued use of the old ship.
