It should be understood that the implementation methods described below in conjunction with the drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application and do not constitute a limitation on the technical solutions of the embodiments of the present application.

[0024] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0025] In order to reduce the cost of rocket launches, the launch vehicle sub-stages can be recovered and reused. The recovery of launch vehicle sub-stages is usually carried out by loading and recovering them using a recovery device at the possible landing site of the launch vehicle sub-stages.

[0026] Considering the diverse and complex environment on land, land-based recycling has high requirements for safety control of the landing area and the selection of landing points. Therefore, considering that the water environment such as lakes and seas is relatively simple and large in area, the safety control and selection requirements of the landing area are relatively low, and water recycling is often used to reduce recycling costs.

[0027] The water recovery platform in the related technology has a single function, which is only capable of receiving and transporting the sub-stage of the launch vehicle. Therefore, after the water recovery platform receives the landed sub-stage of the launch vehicle at the designated recovery location on the water, it needs to be transported to a dedicated technical area on land for inspection and subsequent recovery and reuse, resulting in a long waiting period for recovery. Moreover, during the long transportation process, there is a high possibility of accidents such as bumps, which may cause many problems such as gas and liquid leakage or structural damage, and the safety is poor.

[0028] Furthermore, in the related art, a hoisting method is used to transport the launch vehicle sub-stage. During the hoisting process, the launch vehicle sub-stage may undergo a posture change between a vertical state and an inclined state, resulting in a long transportation time.

[0029] The water recovery device and recovery method of the launch vehicle provided in this application are intended to solve the above-mentioned technical problems of related technologies.

[0030] The following is a detailed description of the technical solution of the present application and how the technical solution of the present application solves the above technical problems with specific embodiments. It should be noted that the following implementations can refer to, draw on or combine with each other, and the same terms, similar features and similar implementation steps in different implementations will not be described repeatedly.

[0031] The embodiment of the present application provides a water recovery device 100 of a carrier rocket, which is used to recover a carrier rocket sub-stage 200 on water. Figure 1 As shown, the above-water recovery device 100 includes: a recovery platform 10 , a maintenance plant 20 and a transfer device 30 .

[0032] The recovery platform 10 is constructed to float on water, and has a recovery pad 11 on its surface for landing the launch vehicle sub-stage 200 .

[0033] The maintenance workshop 20 is disposed on the recycling platform 10 and is spaced apart from the recycling yard 11 .

[0034] The transfer device 30 is used to support and fix the tail of the carrier rocket sub-stage 200 , and to transfer the carrier rocket sub-stage 200 to the maintenance building 20 in a vertical posture.

[0035] In the embodiment of the present application, the surface of the recovery platform 10 has a recovery field 11, and the launch vehicle sub-stage 200 lands on the recovery field 11, is fixed by the transfer device 30 and transferred to the maintenance plant 20 on the recovery platform 10 for maintenance and other recovery treatments. It is not necessary to transport it to a dedicated technical area on land for recovery treatment, which can shorten the waiting recovery period, reduce the possibility of accidents during the waiting recovery period, and improve the safety during the recovery period.

[0036] Moreover, compared with the related art that adopts a hoisting and transportation method to transport the carrier rocket sub-stage 200, in the embodiment of the present application, the carrier rocket sub-stage 200 always maintains the vertical state when landing during the transportation process, which can avoid structural damage and other problems that may be caused in the process of changing the posture of the carrier rocket sub-stage 200 during the hoisting process, and can improve the safety of the transportation process, shorten the transportation time, and improve the transportation efficiency.

[0037] Alternatively, if Figure 2 and Figure 3 As shown, the tail of the launch vehicle sub-stage 200 includes a tail end 201 and a support leg 202. When the support leg 202 is supported on the recovery platform 10, there is a distance between the tail end 201 and the recovery platform 10, which facilitates the transfer device 30 to enter between the launch vehicle sub-stage 200 and the recovery platform 10.

[0038] In some possible embodiments, Figure 1 As shown, the recycling yard 11 and the maintenance workshop 20 are respectively located at two ends of the surface of the recycling platform 10.

[0039] In this embodiment, the recovery yard 11 and the maintenance building 20 are respectively located at the two ends of the surface of the recovery platform 10 and are far apart, so that the carrier rocket sub-stage 200 is far away from the maintenance building 20 during landing, which can minimize the adverse effects of the carrier rocket sub-stage 200 on the maintenance building 20 during the landing process and ensure the structural stability of the maintenance building 20.

[0040] In some possible embodiments, Figure 2 and Figure 3 As shown, the transfer device 30 includes: a support platform 31, moving wheels 32 and a driving device.

[0041] The supporting platform 31 is used to support and fix the tail of the launch vehicle sub-stage 200 .

[0042] The moving wheel 32 is fixedly connected below the supporting platform 31 .

[0043] The driving device is drivingly connected to the moving wheel 32 .

[0044] In this embodiment, the support platform 31 can carry the tail of the launch vehicle sub-stage 200 and fix the tail of the launch vehicle sub-stage 200. The driving device drives the moving wheels 32 to roll on the recovery platform 10, driving the support platform 31 to move, thereby realizing the function of transporting the launch vehicle sub-stage 200.

[0045] Optionally, the transfer device 30 has a hydraulic module, and the support platform 31 can be raised and lowered under the action of the hydraulic module. When it is necessary to enter between the launch vehicle sub-stage 200 and the recovery platform 10, the support platform 31 is controlled to descend. When entering directly under the launch vehicle sub-stage 200, the support platform 31 is controlled to rise, directly receiving the launch vehicle sub-stage 200 and fixedly connected to the launch vehicle sub-stage 200.

[0046] Alternatively, if Figure 3 As shown, the support platform 31 includes a central portion 311 supporting the tail of the launch vehicle sub-stage 200, a peripheral portion 312 located around the central portion 311, and a support seat 313 located on the top of the central portion 311. The moving wheels 32 are all arranged below the peripheral portion 312, so that the central portion 311 is suspended in the air, with a large lifting and adjustment space. Each peripheral portion 312 is arranged between adjacent legs 202 at the tail of the launch vehicle sub-stage 200, and the support seat 313 is restricted by each peripheral portion 312 to prevent the support seat 313 from moving. The tail end 201 of the launch vehicle sub-stage 200 is inserted into the support seat 313 and fixed by the support seat 313.

[0047] In some possible embodiments, Figure 1 As shown, the maintenance building 20 includes a cabin 21 and a maintenance platform 22 .

[0048] The cabin 21 is closed except for the inlet; the inlet faces the recovery yard 11.

[0049] There are multiple maintenance platforms 22 , which are arranged in the cabin 21 at intervals along the vertical direction.

[0050] The plurality of maintenance platforms 22 have recessed areas in a plane parallel to the recovery floor 11 , with openings of the recessed areas facing the recovery floor 11 , and are used to semi-enclose the launch vehicle sub-stage 200 in a plane parallel to the recovery floor 11 .

[0051] In this embodiment, the spatial structure of the maintenance building 20 is formed by a cabin 21, which is fixed on the recovery platform 10. The surface of the recovery platform 10 can be used as the floor of the maintenance building 20. The cabin 21 has only one side opening, which is the entrance and faces the recovery yard 11. This is convenient for the transfer device 30 to directly transfer the carrier rocket sub-stage 200 from the recovery yard 11 to the cabin 21 for maintenance and other recovery treatments, thereby shortening the transfer distance as much as possible, improving the transfer efficiency, and also improving the simplicity of the transfer route to ensure safety during the transfer process.

[0052] Moreover, multiple maintenance platforms 22 are arranged in the cabin 21 at intervals along the vertical direction. Multiple maintenance platforms 22 have recessed areas in a plane parallel to the recovery yard 11, and the openings of the recessed areas face the recovery yard 11, so that the carrier rocket sub-stage 200 can be directly transferred from the recovery yard 11 to the cabin 21 and can directly enter the area enclosed by the recessed areas, making it convenient for operators to perform maintenance on various heights corresponding to the carrier rocket through each maintenance platform 22.

[0053] In addition, the maintenance platform 22 has a fixing device that can fix the launch vehicle sub-stage 200, ensure the stability of the launch vehicle during the maintenance process, reduce the possibility of the launch vehicle sub-stage 200 moving or even tipping over under the influence of external forces, and ensure the smooth progress of the maintenance and other recovery processes.

[0054] In some possible embodiments, the recovery platform 10 includes a hull with a power plant.

[0055] In this embodiment, the power device can provide power for the recovery platform 10, so that the recovery platform 10 moves on the water and transports the launch vehicle sub-stage 200 to a designated location. The recovery platform 10 in this embodiment integrates the power device, and there is no need to set up additional transport ships and other equipment to transport the recovered launch vehicle sub-stage 200, which is conducive to controlling costs.

[0056] In some possible embodiments, Figure 1 As shown, the above-water recovery device 100 further includes a gas-liquid recovery device 40 , which is disposed in the recovery platform 10 .

[0057] In this embodiment, the water recovery device 100 also includes a gas-liquid recovery device 40, which can process the gas or liquid such as fuel remaining in the carrier rocket sub-stage 200 after the carrier rocket sub-stage 200 lands, thereby avoiding adverse safety problems caused by accidental leakage of gas and liquid during the subsequent transportation of the carrier rocket sub-stage 200.

[0058] Moreover, the recovery platform 10 is a hull with a hollow cabin, and the gas-liquid recovery device 40 is arranged inside the recovery platform 10 without occupying the space on the surface of the recovery platform 10. A larger operating space can be reserved for the recovery platform 10, thereby improving the smoothness of the transportation of the carrier rocket sub-stage 200 on the recovery platform 10 and improving the transportation efficiency.

[0059] In some possible embodiments, Figure 1 As shown, the above-water recovery device 100 further includes a spare parts warehouse 50 , which is disposed in the recovery platform 10 .

[0060] In this embodiment, the spare parts warehouse 50 can store commonly used parts for maintenance, replacement, etc. of the carrier rocket sub-stage 200, and can perform maintenance and other recycling processing on the carrier rocket sub-stage 200 during water transportation. There is no need to wait until the carrier rocket sub-stage 200 is transported to a dedicated technical area for recycling, which can shorten the recycling cycle.

[0061] Furthermore, relevant processing can be performed on the carrier rocket sub-stage 200 in a timely manner after the carrier rocket sub-stage 200 lands, thereby reducing the possibility of adverse effects caused by insufficient maintenance.

[0062] Similarly, the recovery platform 10 is a hull with a hollow cabin, and the spare parts warehouse 50 is arranged inside the recovery platform 10 without occupying the space on the surface of the recovery platform 10, which can leave a larger operating space for the recovery platform 10, thereby improving the smoothness of the transportation of the carrier rocket sub-stage 200 on the recovery platform 10 and improving the transportation efficiency.

[0063] In some possible embodiments, the above-water recovery device 100 further includes a launching device disposed on the recovery platform 10 .

[0064] In this embodiment, the water recovery device 100 is also equipped with a launching device, which can launch the carrier rocket sub-stage 200 that has been recovered and can be re-launched. There is no need to transport the carrier rocket sub-stage 200 to a launching device at another launch site for launching, which can improve the utilization rate of the recovery platform 10 and reduce the launch cost.

[0065] Based on the same inventive concept, the present application also provides a method for recovering a launch vehicle, the flow chart of which is as follows: Figure 4 As shown, the method includes steps S101 to S103: S101: Stop the water recovery device 100 provided in any of the above embodiments at a predetermined recovery landing point on the water.

[0066] Optionally, the structural diagram after step S101 is as follows Figure 5 shown.

[0067] S102: After the carrier rocket sub-stage 200 lands on the recovery field 11 on the recovery platform 10 of the water recovery device 100, the transfer device 30 of the water recovery device 100 is controlled to support the tail of the carrier rocket sub-stage 200 and fix it.

[0068] Optionally, the structural diagram after step S102 is as follows: Figure 7 shown.

[0069] S103: Use the transfer device 30 to transfer the carrier rocket sub-stage 200 in a vertical posture to the maintenance workshop 20 of the water recovery device 100.

[0070] Optionally, the structural diagram after step S103 is as follows: Figure 8 shown.

[0071] In this embodiment, if Figure 5-Figure 6 As shown, the water recovery device 100 stops at the predetermined recovery landing point in advance, so that the carrier rocket sub-stage 200 lands on the recovery field 11 on the recovery platform 10. Figure 7 As shown, the transfer device 30 is controlled to be transferred to the bottom of the launch vehicle sub-stage 200, and carries and fixes the launch vehicle sub-stage 200. Then, as shown in FIG. Figure 8 As shown, it is transported to the maintenance plant 20 for maintenance and other recycling processes.

[0072] In the embodiment of the present application, there is no need to transport it to a dedicated technical area on land for recycling and processing, which can shorten the waiting period for recycling, reduce the possibility of accidents during the waiting period for recycling, and improve safety during the recycling period.

[0073] Moreover, compared with the related art that adopts a hoisting and transportation method to transport the carrier rocket sub-stage 200, in the embodiment of the present application, the carrier rocket sub-stage 200 always maintains the vertical state when landing during the transportation process, which can avoid structural damage and other problems that may be caused in the process of changing the posture of the carrier rocket sub-stage 200 during the hoisting process, and can improve the safety of the transportation process, shorten the transportation time, and improve the transportation efficiency.

[0074] In some possible embodiments, after the carrier rocket sub-stage 200 is transferred to the maintenance workshop 20 of the water recovery device 100 by using the transfer device 30 in the above step S103, the following steps are also included: The launch vehicle sub-stage 200 is transported to a designated location by moving the water recovery device 100 .

[0075] In this embodiment, after the carrier rocket sub-stage 200 is transferred to the maintenance plant 20 of the water recovery device 100 by using the transfer device 30, the carrier rocket sub-stage 200 is transported to a designated location by moving the water recovery device 100 to carry out the next recovery operation, such as docking with other equipment, assembly or launch.

[0076] In some possible embodiments, the above steps of transporting the launch vehicle sub-stage 200 to a designated location by moving the water recovery device 100 include the following steps: In the process of transporting the carrier rocket sub-stage 200 to the designated location by the mobile recovery platform 10, the carrier rocket sub-stage 200 is overhauled by the overhaul plant 20; the recovery platform 10 includes a hull and has a power device.

[0077] In this embodiment, during the recovery process in the maintenance plant 20, the water recovery device 100 can transport the carrier rocket sub-stage 200 to a designated location. The recovery process and the transportation process of the carrier rocket sub-stage 200 can be carried out simultaneously, which can shorten the recovery cycle.

[0078] In some possible embodiments, after the transfer device 30 of the above-water recovery device 100 is controlled to support and fix the tail of the carrier rocket sub-stage 200 in the above step S102, and before the carrier rocket sub-stage 200 is transferred to the maintenance workshop 20 of the above-water recovery device 100 by the transfer device 30 in the above step S103, the following steps are also included: The gas and liquid remaining in the launch vehicle sub-stage 200 are processed by the gas and liquid recovery device 40 located inside the recovery platform 10.

[0079] In this embodiment, after the carrier rocket sub-stage 200 lands on the recovery site 11, the gas and liquid recovery operation can be performed on the carrier rocket sub-stage 200 in a timely manner, and the gas and liquid substances remaining in the carrier rocket sub-stage 200 can be handled in a timely manner to avoid adverse safety problems caused by accidental leakage of gas and liquid during the subsequent transportation of the carrier rocket sub-stage 200.

[0080] In some possible embodiments, after transporting the carrier rocket sub-stage 200 to a designated location by moving the water recovery device 100, the method further includes: The overhauled carrier rocket sub-stage 200 is docked with the launching device of the water recovery device 100 for launching.

[0081] In this embodiment, the water recovery device 100 is also equipped with a launching device, which can launch the carrier rocket sub-stage 200 that has been recovered and can be re-launched. There is no need to transport the carrier rocket sub-stage 200 to a launching device at another launch site for launching, which can improve the utilization rate of the recovery platform 10 and reduce the launch cost.

[0082] By applying the embodiments of the present application, at least the following beneficial effects can be achieved: 1. The recovery platform 10 has a recovery field 11 on its surface. The launch vehicle sub-stage 200 lands on the recovery field 11, is fixed by a transfer device 30, and is transferred to a maintenance plant 20 on the recovery platform 10 for maintenance and other recovery treatments. It is not necessary to transport it to a special technical area on land for recovery treatment, which can shorten the waiting recovery period, reduce the possibility of accidents during the waiting recovery period, and improve the safety during the recovery period.

[0083] 2. Compared with the related art that adopts the hoisting transportation method to transport the carrier rocket sub-stage 200, in the embodiment of the present application, during the transportation process, the carrier rocket sub-stage 200 always maintains the vertical state when landing, which can avoid structural damage and other problems that may be caused in the process of changing the posture of the carrier rocket sub-stage 200 during the hoisting process, and can improve the safety of the transportation process, shorten the transportation time, and improve the transportation efficiency.

[0084] 3. The maintenance plant 20 is set on the recovery platform 10. The transfer system can transport the carrier rocket sub-stage 200 to the maintenance plant 20 for maintenance and other recovery treatments in a relatively short time, which can reduce the possibility of accidents during transportation and further improve the safety of the transportation process.

[0085] 4. The spatial structure of the maintenance building 20 is formed by a cabin 21, which is fixed on the recovery platform 10. The surface of the recovery platform 10 can be used as the floor of the maintenance building 20. The cabin 21 has only one opening, which is the entrance and faces the recovery yard 11. This makes it convenient for the transfer device 30 to directly transfer the carrier rocket sub-stage 200 from the recovery yard 11 to the cabin 21 for maintenance and other recovery treatments, thereby shortening the transfer distance as much as possible, improving the transfer efficiency, and also improving the simplicity of the transfer route to ensure safety during the transfer process.

[0086] 5. Multiple maintenance platforms 22 are arranged in the cabin 21 at intervals in the vertical direction. Multiple maintenance platforms 22 have recessed areas in a plane parallel to the recovery yard, and the openings of the recessed areas face the recovery yard 11, so that the carrier rocket sub-stage 200 can be directly transferred from the recovery yard 11 to the cabin 21 and can directly enter the area enclosed by the recessed areas, which is convenient for operators to perform maintenance on various heights corresponding to the carrier rocket through each maintenance platform 22.

[0087] 6. The maintenance platform 22 has a fixing device that can fix the launch vehicle sub-stage 200, ensure the stability of the launch vehicle during the maintenance process, reduce the possibility of the launch vehicle sub-stage 200 moving or even tipping over under the influence of external forces, and ensure the smooth progress of the maintenance and other recovery processes.
