Description

Technical Field

[0001] This invention relates to the technical field of sea-based rocket launches, and more particularly to a rapid opening device and control method for preventing overturning during sea-based rocket launches. Background Technology

[0002] Currently, sea-based rocket launches have become an important method. Compared with land-based rockets, sea-based launches have advantages such as greater flexibility, better mission adaptability, and lower launch costs. More and more low-orbit satellites will choose to launch from sea in the future.

[0003] However, sea launch conditions are affected by sea conditions and weather. The uncertainty of waves at sea causes the ship to roll and pitch, which are transmitted to the launch platform, affecting the stability of the rocket before and after erection. The stability of the rocket after erection on the launch platform is poor. Due to the large overturning moment caused by the ship's swaying, the rocket structure is prone to failure, or even overturning. Excessive tilt angle of the rocket not only affects the accuracy of launch control but may also lead to overturning, resulting in launch failure or even a launch accident. Therefore, ensuring that the rocket maintains a stable and safe attitude during the free-standing phase before ignition has become a crucial issue.

[0004] Before rocket ignition and launch, the anti-tipping device for sea-launched rockets needs to be tilted to separate it from the rocket body, allowing for a successful launch. However, during sea launches, the ship's swaying necessitates the flight control system to correct the rocket's attitude during takeoff, resulting in a certain amount of drift. This takeoff drift places specific requirements on the opening speed of the anti-tipping arm. Generally, anti-tipping devices rely solely on their own weight to tilt and open. Increasing the opening speed would require increasing the weight of the anti-tipping arm, which is inconvenient for adjusting the opening speed. Furthermore, the increased weight of the anti-tipping arm places a significant strain on the strength of the anti-tipping base.

[0005] Therefore, the urgent problem to be solved is how to design a solution that can more efficiently improve the opening speed and allow for adjustment of the opening speed, with minimal increase in the weight of the anti-tipping arm. Summary of the Invention

[0006] This invention addresses the shortcomings of existing technologies by providing a rapid opening device and control method for preventing overturning during sea-based rocket launches, thereby improving the safety and reliability of sea-based rocket launches.

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A quick-opening device for preventing overturning during a marine rocket launch includes an anti-overturning base and a drive base. An anti-overturning arm is hinged to the anti-overturning base. The rocket body is placed on the anti-overturning base, and the anti-overturning arm is positioned on one side of the rocket body. A drive assembly is provided on the drive base to drive the rotation of the anti-overturning arm. A brake flywheel assembly is provided inside the anti-overturning arm to brake the rotation of the anti-overturning arm. The drive assembly and the brake flywheel assembly are connected by a coupling.

[0008] Furthermore, the drive assembly includes a drive motor and a reduction motor. The reduction motor is connected to a lead screw slide, and the drive motor is connected to a magnetic coupling II. The drive motor and the brake flywheel assembly are connected through the magnetic coupling II.

[0009] Furthermore, the brake flywheel assembly includes a brake flywheel base, with support frames on both sides of the brake flywheel base. The support frames include a left support frame and a right support frame. A spline shaft is rotatably connected between the left support frame and the right support frame. A brake drum and several flywheel discs are sleeved on the spline shaft. A magnetic coupling is provided at one end of the spline shaft near the drive assembly. The magnetic coupling is connected to a magnetic coupling.

[0010] Furthermore, the brake drum is provided with linear guide rails on both sides of the support frame, and a wedge-shaped brake block is slidably connected on the linear guide rail. A connecting rod and an inner rocker arm are provided on one side of the wedge-shaped brake block.

[0011] Furthermore, the left support frame, on the side away from the brake drum, is equipped with a magnetic actuator, an outer rocker arm, a thrust spring, an operating handle, a second connecting rod, a turntable, and a stop block. The end of the second connecting rod is hinged to the end of the outer rocker arm, and the end of the outer rocker arm away from the second connecting rod is hinged to the end of the thrust spring. The end of the thrust spring away from the outer rocker arm is hinged to the left support frame. The inner rocker arm is connected to the outer rocker arm and rotates synchronously. The end of the inner rocker arm is hinged to the end of the first connecting rod, and the end of the first connecting rod away from the inner rocker arm is hinged to the wedge-shaped brake block. The wedge-shaped brake block cooperates with the linear guide rail to perform linear motion, and the wedge-shaped brake block rubs against the brake drum to perform braking motion.

[0012] A control method for a rapid opening device for preventing overturning during a marine rocket launch, based on the aforementioned rapid opening device, includes a launch process. At the start of the rocket launch process, the drive assembly and brake flywheel assembly are reset to their initial positions. The drive motor, driven by a lead screw slide, moves towards the brake flywheel assembly, engaging magnetic coupling one and magnetic coupling two. The drive motor then slowly accelerates, causing the anti-overturning arm to tilt in the reverse direction and reach the target speed value determined during debugging. The drive motor, driven by the lead screw slide, moves away from the brake flywheel assembly, disengaging magnetic coupling one and magnetic coupling two. The rocket body ignites, the anti-overturning arm tilts forward, and the rocket launch process begins.

[0013] Furthermore, the reset procedure includes checking the wear of the wedge brake block and brake drum after the anti-rollover arm is reset to the closed state, installing the flywheel according to the target speed of the drive motor and the number of flywheel blades, adjusting the tilting speed of the anti-rollover arm, and pulling down the operating handle to release the brake flywheel assembly after the brake flywheel assembly is assembled.

[0014] Furthermore, the process for handling coupling failure involves first setting a timeout value after the drive motor issues a rightward displacement command. After the timeout value, a position switch is used to check whether the drive motor has reached its position. If it has not, then magnetic coupling one and magnetic coupling two have not properly separated, and a coupling failure alarm will be issued. The system will then avoid the anti-tipping arm and restart the drive motor to ensure that the flywheel is within the expected speed range before the anti-tipping arm separates. After the anti-tipping arm begins to tilt, the drive motor will be shut off.

[0015] Furthermore, the drive motor fault handling process firstly identifies the drive motor fault signal while magnetic coupling one and magnetic coupling two are engaged, and determines that the fault will cause the flywheel to decelerate suddenly. At the same time, the speed signal at the flywheel end is collected to determine whether the speed is decreasing. If the speed signal is decreasing, the drive motor is stopped immediately, magnetic coupling one and magnetic coupling two are separated, and a rapid deceleration alarm is sent. If the fault does not affect the normal operation of the flywheel, a failure alarm is sent.

[0016] Furthermore, the braking over-limit handling process involves recording the flywheel speed at each time point and the corresponding flywheel end speed encoder, comparing it with the set sample value. If the flywheel speed is within the range, the flywheel is decelerating normally. If it exceeds the set sample value range, the braking is over-limit or malfunctioning, and a braking over-limit alarm is issued. The anti-tipping arm status changes from rapid opening to opening only by its own weight.

[0017] In summary, compared with the prior art, the beneficial effects of the above technical solution are: 1. The present invention has an adjustable tipping speed, which can be adjusted according to the target speed of the drive motor and the number of flywheel blades to achieve the tipping speed of the anti-tipping arm.

[0018] 2. This invention can reduce the total mass of the anti-tipping arm by using the external energy generated by the rotation speed of the flywheel to replace the increased weight of the anti-tipping arm or by using counterweights to increase the tipping speed.

[0019] 3. In this invention, when the equipment malfunctions, the drive motor shaft and the spline shaft of the flywheel are not rigidly connected due to the use of a magnetic coupling, so it will not affect the normal tilting of the anti-tipping arm without external force.

[0020] 4. This invention uses flywheel plates for energy storage and releases energy during the tilting process, resulting in higher energy density compared to the counterweight method.

[0021] 5. The braking force of the present invention is not only applied by the thrust spring, but also by the wedge-shaped brake block, which can also obtain a greater braking force. Attached Figure Description

[0024] The principles and features of the present invention are described below with reference to all the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0025] This invention discloses a rapid opening device and its control method for preventing overturning during marine rocket launches.

[0026] Reference Figures 1 to 8 As shown, a quick-opening device for preventing overturning during a marine rocket launch includes an anti-overturning base 4 and a drive base 3. An anti-overturning arm 6 is hinged to the anti-overturning base 4. The rocket body 1 is placed on the anti-overturning base 4, and the anti-overturning arm 6 is placed on one side of the rocket body 1. A drive assembly 2 is provided on the drive base 3. The drive assembly 2 is used to drive the rotation of the anti-overturning arm 6. A brake flywheel assembly 5 is provided inside the anti-overturning arm 6. The brake flywheel assembly 5 is used to brake the rotation of the anti-overturning arm 6. The drive assembly 2 and the brake flywheel assembly 5 are connected by a coupling.

[0027] The drive assembly 2 includes a drive motor 30 and a geared motor 31. The geared motor 31 is connected to a lead screw slide 32, and the drive motor 30 is connected to a magnetic coupling 33. The drive motor 30 is connected to the brake flywheel assembly 5 through the magnetic coupling 33.

[0028] The drive motor 30 is mounted on the lead screw slide 32. The reduction motor 31 drives the lead screw to rotate, which can make the drive motor 30 move left and right. A coupling is also mounted on the shaft of the drive motor 30. When the anti-tipping arm 6 is not opened, the coupling with the brake flywheel assembly 5 is coaxial.

[0029] The brake flywheel assembly 5 includes a brake flywheel base 18. Support frames are provided on both sides of the brake flywheel base 18. Each support frame includes a left support frame 24 and a right support frame 19. A splined shaft 15 is rotatably connected between the left support frame 24 and the right support frame 19. A brake drum 10 and several flywheel discs 16 are mounted on the splined shaft 15. A magnetic coupling 17 is provided at one end of the splined shaft 15 near the drive assembly 2, and the magnetic coupling 17 is connected to a magnetic coupling 33. Linear guide rails 11 are provided on both sides of the brake drum 10 and mounted on the support frames. Wedge-shaped brake blocks 12 are slidably connected to the linear guide rails 11. A connecting rod 13 and an inner rocker arm 14 are provided on one side of the wedge-shaped brake block 12.

[0030] The left support frame 24, on the side away from the brake drum 10, is equipped with a magnetic actuator 20, an outer rocker arm 21, a thrust spring 22, an operating handle 23, a connecting rod 25, a turntable 26, and a stop block 27. The end of the connecting rod 25 is hinged to the end of the outer rocker arm 21. The end of the outer rocker arm 21 away from the connecting rod 25 is hinged to the end of the thrust spring 22. The end of the thrust spring 22 away from the outer rocker arm 21 is hinged to the left support frame 24. The inner rocker arm 14 is connected to the outer rocker arm 21 and rotates synchronously. The end of the inner rocker arm 14 is hinged to the end of the connecting rod 13. The end of the connecting rod 13 away from the inner rocker arm 14 is hinged to the wedge brake block 12. The wedge brake block 12 cooperates with the linear guide rail 11 to make linear motion. The wedge brake block 12 makes frictional contact with the brake drum 10 to make braking motion.

[0031] The left support bracket 24 and the right support bracket 19 are mounted on the brake flywheel base 18. The mounting hole of the right support bracket 19 is selected according to the number of flywheel plates 16. The spline shaft 15 passes through the bearing hole of the left support bracket 24 and the bearing hole of the right support bracket. One end of the spline shaft 15 is connected to the magnetic coupling 17.

[0032] From left to right, the splined shaft 15 consists of a brake drum 10 and several sequentially arranged flywheel plates 16, all connected as a single unit using keyways. The remaining portion of the brake flywheel assembly 5 is mounted on the left support frame 24. The operating handle 23 rotates with the turntable 26, and a stop block 27 is located at the end of the turntable 26's rotation. Multiple connecting rods 25 are symmetrically hinged to the left and right sides of the turntable 26. The hinge holes of the connecting rods 25 are simultaneously hinged to the connecting rod of the magnetic actuator 20, and the other end of the magnetic actuator 20 is hinged to the left support frame 24.

[0033] The other end of the connecting rod 25 on the turntable 26 is hinged to the outer rocker arm 21, which is also hinged to the thrust spring 22. The other end of the thrust spring 22 is hinged to the left support frame 24. The inner rocker arm 14 is connected to the outer rocker arm 21 and can rotate simultaneously. The other end of the inner rocker arm 14 is hinged to the connecting rod 13 on the wedge brake block 12, and the other end of this connecting rod 13 is hinged to the wedge brake block 12. The slider of the wedge brake block 12 cooperates with the linear guide rail 11 mounted on the left support frame 24 to perform linear motion. When the wedge brake block 12 performs braking motion, it makes frictional contact with the brake drum 10.

[0034] The present invention has an adjustable tipping speed, which is adjusted according to the target speed of the drive motor 30 and the number of flywheel plates 16. It can reduce the total mass of the anti-tipping arm 6 and increase the tipping speed by using the external energy of the flywheel plate 16 rotation speed instead of increasing the weight of the anti-tipping arm 6 or by using counterweight.

[0035] When equipment malfunctions, the use of a magnetic coupling, rather than a rigid connection between the drive motor 30 shaft and the splined shaft 15 of the flywheel 16, does not affect the normal tilting of the anti-tipping arm 6 without external force. This invention uses the flywheel 16 for energy storage and releases energy during the tilting process, resulting in higher energy density compared to a counterweight method. Braking force is not only applied via the thrust spring 22, but also through the wedge-shaped brake block 12, providing greater braking force.

[0036] Reference Figures 1 to 8 As shown in the figure, an embodiment of the present invention provides a control method for a quick-opening device for preventing overturning during a marine rocket launch. Based on the aforementioned quick-opening device for preventing overturning during a marine rocket launch, the specific usage process is as follows: 1. Launch procedure: The rocket body 1 launch process begins. After all components are reset and in the initialization position, the drive motor 30 moves to the left under the drive of the lead screw slide 32 until it reaches the left end, engaging magnetic coupling 17 and magnetic coupling 33. The drive motor 30 then slowly accelerates, and the anti-tipping arm 6 moves in the opposite direction of the tipping direction, reaching the target speed determined during debugging. The drive motor 30 then moves to the right under the drive of the lead screw slide 32 until it reaches the right end. The drive motor 30 stops, disengaging magnetic coupling 17 and magnetic coupling 33. The rocket ignites, and the anti-tipping arm 6 begins to rotate in the forward direction, i.e., the backward direction.

[0037] When the rotary encoder and angle encoder at the pivot of the anti-tipping arm 6 collect incremental signals that reach the required preset value, the magnetic actuator 20 works for one cycle (contraction-release), pulling the connecting rod 25 on the turntable 26, causing the turntable 26 to leave the limit and pass the dead point position. Subsequently, under the action of the thrust spring 22, the large rocker arm drives the small rocker arm to rotate, pushing the wedge brake block 12 to contact the brake drum 10. Due to the combined action of friction and the rotation direction of the brake drum 10, the wedge brake block 12 is tightly wedged in the gap between the brake drum 10 and the left support frame 24, and the braking force is significantly increased.

[0038] According to Newton's third law, when the flywheel plate 16 reaches the target speed, it has a certain angular momentum. At this time, braking the flywheel plate 16 is equivalent to the braking flywheel assembly 5 applying a positive torque to the flywheel plate 16, which is the tilting direction of the anti-rollover arm 6. Since the braking flywheel assembly 5 is installed on the anti-rollover arm 6, it will drive the anti-rollover arm 6 to rotate in the positive direction, thereby accelerating the tilting of the anti-rollover arm 6.

[0039] 2. Reset Procedure: After the anti-rollover arm 6 is reset to the closed state, adjust the number of flywheel plates 16 as needed, check the wear of the wedge brake block 12 and brake drum 10 to see if they need to be replaced, and confirm whether the wedge brake block 12 or brake drum 10 needs to be replaced. The tilting speed of the anti-rollover arm 6 can be adjusted according to the target speed of the drive motor 30 and the number of flywheel plates 16. After the brake flywheel assembly 5 is assembled, pull down the operating handle 23 to the release state, so that the multi-link mechanism is blocked by the stop block 27 after passing the dead point and is locked by the spring force of the thrust spring 22, thereby releasing the brake flywheel assembly 5.

[0040] 3. Procedure for handling couplings that are not disassembled: Due to faults such as jamming of the lead screw slide 32 or damage to the geared motor 31, the magnetic coupling 17 and the magnetic coupling 33 failed to separate successfully. If the drive motor 30 is stopped at this time, the speed of the flywheel 16 will decrease. When the anti-tipping arm 6 falls backward, the expected acceleration will not be obtained. Therefore, it is necessary to check and deal with the failure of the coupling to separate.

[0041] First, a timeout value is set after the drive motor 30 issues a rightward displacement command. After the timeout value, the position switch checks whether the drive motor 30 has reached its position. If it has not, the coupling has not properly disengaged. At this time, a coupling disengagement alarm will be issued so that other systems can make adjustments to avoid the anti-tipping arm 6 and restart the drive motor 30 to ensure that the flywheel 16 is within the expected speed range before the anti-tipping arm 6 disengages. After the anti-tipping arm 6 begins to tilt, magnetic coupling 17 and magnetic coupling 33 are forcibly disengaged, and finally, the drive motor 30 is turned off.

[0042] In other words, when the flywheel speed reaches the set value and the timeout value is reached after the command to move the right end of the lead screw slide 32 (i.e., move to the right) is issued, it indicates that the coupling has not been properly disengaged and the lead screw slide 32 is in the left position (i.e., moving to the left). At this time, a warning message is sent, the drive motor 30 is restarted and reaches the set speed, and at the same time, the angle encoder and rotary encoder of the anti-tipping arm 6 reach the preset value, and then the drive motor 30 stops.

[0043] 4. Troubleshooting procedures for drive motor 30 and frequency converter: When the drive motor 30 and the frequency converter are short-circuited, short-circuited between turns, or missing a phase, or short-circuited in the power module, the speed will drop sharply and the running resistance will increase. This will cause the flywheel plate 16 to decelerate suddenly and release the stored kinetic energy in advance, resulting in the anti-tipping arm 6 opening device bearing huge pressure. Therefore, such faults need to be handled during use.

[0044] First, with magnetic coupling 17 engaged and magnetic coupling 33 engaged, scan the fault signal of the frequency converter drive and determine whether the fault will cause the flywheel 16 to decelerate suddenly. At the same time, collect the speed signal at the end of the flywheel 16 to determine whether the speed is decreasing.

[0045] If any of the above conditions are met, the drive motor 30 will be stopped immediately, the magnetic coupling will be disengaged, and a drive system emergency deceleration alarm will be sent to coordinate with other systems and prevent excessive impact on the flywheel 16. If the fault is another fault that does not affect the normal operation of the flywheel 16, a drive system failure alarm will be sent.

[0046] In other words, firstly, the lead screw slide 32 moves to the left position, that is, it moves to the left. At the same time, the speed encoder at the flywheel end reads the value of abnormal speed drop. If the drive motor 30 alarms for any of the following: motor phase open circuit, motor turn open circuit, power supply phase loss, or driver IGBT module short circuit, then the drive motor 30 stops working. At this time, the lead screw slide 32 moves to the right position (that is, it moves to the right) and sends a drive system emergency deceleration fault warning. If the driver alarm indicates another fault, a driver system failure warning will be sent.

[0047] 5. Braking over-limit handling procedure: When the brake flywheel assembly 5 is excessively worn or its structure or magnetic actuator 20 is damaged, it will cause brake failure due to over-limit.

[0048] By recording the rotational speed of the flywheel 16 at each time point after opening and the corresponding speed encoder at the flywheel 16 end, the speed is compared with the set sample. If it is within the range, the flywheel 16 is decelerating normally. If it exceeds the range, the brake is over-limit or malfunctioning. At this time, a brake over-limit alarm is issued to notify other systems, and the anti-tipping arm 6 state changes from rapid opening to opening by its own weight.

[0049] In other words, the system judges whether the angle encoders and rotary encoders installed on the anti-tipping arm 6 have reached the preset values, calculates and compares whether the speed collected by the flywheel end speed encoder is within the expected range, and when it is detected that the current speed is not within the expected range, it sends a brake over-limit warning, and the anti-tipping arm 6 changes from rapid opening to opening only by its own weight.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

A coupling failure alarm will be issued, the anti-tipping arm (6) will be avoided, and the drive motor (30) will be restarted to ensure that the flywheel plate (16) is within the expected speed range before the anti-tipping arm (6) is separated. After the anti-tipping arm (6) begins to tilt, the drive motor (30) will be turned off.

9. The control method for a rapid opening device for preventing overturning during a marine rocket launch according to claim 6, characterized in that, The fault handling process for the drive motor (30) includes the following steps: First, with the magnetic coupling one (17) and magnetic coupling two (33) engaged, the fault signal of the drive motor (30) is identified, and it is determined that the fault will cause the flywheel plate (16) to decelerate suddenly. At the same time, the speed signal at the end of the flywheel plate (16) is collected to determine whether the speed is decreasing. If the speed signal is decreasing, the drive motor (30) is stopped immediately, and the magnetic coupling one (17) and magnetic coupling two (33) are separated. Then, a rapid deceleration alarm is sent. If the fault does not affect the normal operation of the flywheel plate (16), a failure alarm is sent.

10. The control method for a rapid opening device for preventing overturning during a marine rocket launch according to claim 6, characterized in that, The braking over-limit handling process includes recording the speed of the flywheel (16) at each time point and the corresponding flywheel (16) end speed encoder, comparing it with the set sample value. If the speed of the flywheel (16) is within the range, the flywheel (16) is decelerating normally. If it exceeds the set sample value range, the braking is over-limit or malfunctioning, and a braking over-limit alarm is issued. The anti-tipping arm (6) state changes from rapid opening to opening only by its own weight.
