Description

Technical Field

[0001] This invention relates to the field of rotating body water immersion test technology, specifically to a series-parallel launching mechanism and test device. Background Technology

[0002] In fields such as marine engineering, underwater weapons, and airdrop equipment, the study of the dynamic characteristics of objects entering water at high speeds is of great significance. During the water entry process, the object is subjected to complex fluid impact loads, cavitation effects, and structural responses, which directly affect the object's motion stability, structural integrity, and functional reliability. Therefore, conducting high-speed water entry tests is an important means to verify theoretical models, optimize design parameters, and improve performance.

[0003] In missions such as weapon MIRVs, underwater cluster operations, or multi-stage water entry, it is often necessary to study the interaction laws of multiple objects entering the water simultaneously or sequentially. Traditional water entry test devices typically use a single launcher for testing. For example, CN116576723A discloses a parallel water entry test device for vehicles with adjustable launch speed, angle, and timing, including an electromagnetic railgun launching platform, an angle adjustment frame, and a test pool. The electromagnetic railgun launching platform is used to launch projectiles in parallel into the test pool for parallel water entry tests. Another example is a piston-type multi-projectile tandem launch structure disclosed in CN112432563B, which includes a barrel, a propellant chamber, and a complete projectile body. In this design, the high-temperature, high-pressure gas generated by ignition enters the gas chamber through a vent. After a certain period of time, the high-temperature, high-pressure gas enters the front cavity of the cartridge case through a vent on the piston, increasing the pressure in the front cavity. After the projectile detaches from the muzzle and enters the water, the pressure difference between the inside and outside of the projectile causes the groove to break, and the projectile disintegrates. The projectile then moves in the water in series, and a supercavitation bubble is formed around the projectile to reduce drag and significantly reduce the drag of the projectile body.

[0004] However, traditional water entry devices typically employ a single series or parallel layout, which necessitates the replacement of different launch devices when conducting multi-body coordinated water entry or time-sequential water entry tests. This not only increases the complexity and cost of the tests but also limits the flexibility and applicability of the tests, failing to meet the needs of different test modes such as series and parallel connections. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a series-parallel launch mechanism and test device to solve the technical problem that traditional water entry test devices in the prior art usually only support single launcher or fixed arrangement of multiple launchers, and cannot flexibly switch between series (sequential water entry) or parallel (synchronous water entry) modes according to needs.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a series-parallel launching mechanism, comprising: a launching section, a driving structure, and an energy supply structure. The launching section includes a main body, a movable launching member movably mounted on the main body, and a fixed launching member fixedly mounted on the main body. The driving structure connects the main body and the movable launching member, and is capable of driving the movable launching member to move to a first position arranged parallel to the fixed launching member, and to move to a second position arranged coaxially and in series with the fixed launching member. The energy supply structure connects the fixed launching member and the movable launching member, and is used to provide launching energy to the fixed launching member and the movable launching member respectively.

[0007] In some embodiments, the movable launching member includes a first projectile tube and a first launching body. The first projectile tube is connected to the driving structure, and the first launching body is disposed inside the first projectile tube for launching along the trajectory of the first projectile tube under the drive of the energy supply structure. The fixed launching member includes a second projectile tube and a second launching body. The second projectile tube is fixedly installed on the main body, and the second launching body is disposed inside the second projectile tube for launching along the trajectory of the second projectile tube under the drive of the energy supply structure.

[0008] In some embodiments, the drive structure includes a mounting base and a rotary drive member. One end of the mounting base is rotatably connected to the main body, and the other end is connected to one end of the first projectile tube. The rotary drive member is connected to the mounting base and is used to drive the mounting base to rotate relative to the main body, thereby causing the movable launcher to switch between a first position and a second position.

[0009] In some embodiments, the first projectile tube has a first connecting end and a second connecting end at its two ends, respectively. The first connecting end is connected to the mounting base. When the movable launcher moves to the first position, the second connecting end of the first projectile tube is sealed to the main body. When the movable launcher moves to the second position, the first connecting end of the first projectile tube is sealed to the movable launcher through the mounting base. The sidewalls of the first connecting end and the second connecting end are provided with interfaces, and the energy supply structure is connected through the interfaces. The installation position of the first launcher is between the two interfaces.

[0010] In some embodiments, the energy supply structure includes a first gas supply component and a second gas supply component. The first gas supply component has two supply ports, and the two supply ports of the first gas supply component are respectively connected to the side wall interfaces of the first connection end and the second connection end. The output end of the second gas supply component is connected to the interior of the fixed transmitter.

[0011] In some embodiments, the series-parallel launching mechanism further includes a position adjustment structure, which includes a fixed base and a displacement driving member. The fixed base is mounted on the main body. When the movable launching member moves to the first position, one end of the movable launching member is connected to the fixed base, and one end of the displacement driving member is connected to the main body, while the other end is connected to the fixed base, so as to drive the fixed base to move relative to the fixed launching member, thereby causing the movable launching member to move relative to the fixed launching member.

[0012] In some embodiments, the series-parallel launching mechanism further includes a locking mechanism, which includes two locking components. The two locking structures are respectively installed on one side of the first projectile tube and the second projectile tube, and each has a telescopic locking end. The telescopic locking end has a locked state connected to the first projectile or the second projectile and an unlocked state disconnected from the first projectile or the second projectile.

[0013] In some embodiments, the locking mechanism further includes an adjustment component connected to one of the locking components for driving the locking component to move relative to the other locking component to adjust the distance between the first transmitter and the second transmitter.

[0014] In some embodiments, the series-parallel transmitting mechanism further includes a control module connected to the energy supply structure, which is used to synchronously or independently control the triggering timing and transmission energy of the fixed transmitter and the movable transmitter through the energy supply structure.

[0015] Secondly, the present invention also provides a test apparatus, including a series-parallel transmission mechanism as described in any of the above claims.

[0016] Compared with existing technologies, the parallel launch mechanism and test device provided by this invention, by setting up a launch unit, a drive structure, and an energy supply structure, and by controlling the position of the movable launcher through the drive structure, achieves rapid switching between parallel (side-by-side arrangement) and series (coaxial arrangement) launch modes. It can easily switch between series and parallel water entry test modes, effectively solving the problem of the single test mode of traditional devices, greatly expanding the application range and flexibility of the test, and optimizing space utilization. The energy supply structure is used to supply energy to the fixed and movable launchers, ensuring the energy synchronization and stability of the dual launch units, and improving launch efficiency and reliability.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] To address the technical problem that traditional water entry test devices typically only support single-launcher or fixed-arrangement multi-launcher tests and cannot flexibly switch between series (sequential water entry) or parallel (synchronous water entry) modes as needed, this invention provides a series-parallel launch mechanism and test device that enables flexible switching between series and parallel launch modes, greatly improving the flexibility and applicability of the test.

[0021] Please see Figures 1 to 7 In a first aspect, embodiments of the present invention provide a series-parallel launching mechanism, comprising: a launching unit 1, a driving structure 2, and an energy supply structure 3. The launching unit 1 includes a main body 11, a movable launching member 12 movably mounted on the main body 11, and a fixed launching member 13 fixedly mounted on the main body 11. The driving structure 2 connects the main body 11 and the movable launching member 12, and is capable of driving the movable launching member 12 to move to a first position arranged parallel to the fixed launching member 13, and to move to a second position arranged coaxially and in series with the fixed launching member 13. The energy supply structure 3 connects the fixed launching member 13 and the movable launching member 12, and is used to provide launching energy to the fixed launching member 13 and the movable launching member 12 respectively.

[0022] In this device, the movable launcher 12 and the fixed launcher 13 are mounted on the main body 11 in a movable and fixed manner, respectively. The position of the movable launcher 12 can be controlled by the drive structure 2, allowing it to move to a first position or a second position. When the movable launcher 12 moves to the first position, it is arranged side by side with the fixed launcher 13, allowing for simultaneous launch of both to conduct parallel synchronous water entry tests. When the movable launcher 12 moves to the second position, it is coaxially connected in series with the fixed launcher 13, allowing for simultaneous launch of either the movable launcher 12 or the fixed launcher 13 to conduct parallel sequential water entry tests. The energy supply structure 3 provides launch energy to both the fixed launcher 13 and the movable launcher 12, ensuring a stable energy supply and enabling precise control of the launch test.

[0023] In series mode, the movable launcher 12 and the fixed launcher 13 are arranged coaxially, enabling synchronous or orderly launch into the water to simulate a multi-body series entry into the water scenario. This is suitable for studying the interaction between objects and the overall motion characteristics. In parallel mode, the movable launcher 12 and the fixed launcher 13 are arranged side by side, allowing for independent launch to simulate a multi-body parallel entry into the water scenario. This helps in analyzing the water entry response and performance of individual objects.

[0024] Please see Figure 1 and Figure 2Preferably, in this embodiment, both the movable launcher 12 and the fixed launcher 13 are composed of a missile tube and a launcher body. The movable launcher 12 includes a first missile tube 121 and a first launcher body 122, and the fixed launcher 13 includes a second missile tube 131 and a second launcher body 132. The first missile tube 121 is connected to the drive structure 2, and the first launcher body 122 is disposed inside the first missile tube 121 for launching along the trajectory of the first missile tube 121 under the drive of the energy supply structure 3. The second missile tube 131 is fixedly installed on the main body 11, and the second launcher body 132 is disposed inside the second missile tube 131 for launching along the trajectory of the second missile tube 131 under the drive of the energy supply structure 3.

[0025] Please see Figure 1 and Figure 2 In some possible embodiments, the drive structure 2 uses rotation to switch the movable launcher 12 between a first position and a second position. It includes a mounting base 21 and a rotation drive 22. The two ends of the first projectile tube 121 form a first connecting end 1211 and a second connecting end 1212, respectively. Specifically, one end of the mounting base 21 is fitted over the outside of the first connecting end 1211 of the first projectile tube 121 and partially protrudes from one end of the first projectile tube 121. The other end of the mounting base 21 is rotatably connected to the main body 11. The rotation drive 22 is connected to the mounting base 21 and drives the mounting base 21 to rotate relative to the main body 11, thereby switching the movable launcher 12 between the first and second positions. When the movable launcher 12 switches between the first and second positions, the rotation angle of the rotation drive 22 is 180° each time.

[0026] Driven by the rotary drive 22, when the movable launcher 12 moves to the first position, the second connecting end 1212 of the first projectile tube 121 is sealed to the main body 11. The first projectile tube 121 and the second projectile tube 131 are arranged side by side, and a parallel water immersion test can be performed. When the movable launcher 12 moves to the second position, the mounting base 21 rotates to the bottom of the second projectile tube 131, and the part of it protruding from the first projectile tube 121 is fitted onto the bottom of the second projectile tube 131, so that the first connecting end 1211 of the first projectile tube 121 is sealed to the movable launcher 12 through the mounting base 21. At this time, the first projectile tube 121 and the second projectile tube 131 are coaxially connected, and a series water immersion test can be performed.

[0027] Furthermore, since the positions of the two ends of the movable launching member 12 are opposite in the first and second positions, to ensure accurate launching in the first and second positions, please refer to [reference needed]. Figures 1 to 4In some possible embodiments, interfaces 1213 are provided on the sidewalls of the first connecting end 1211 and the second connecting end 1212 of the first projectile tube 121. The installation position of the first launcher 122 is between the two interfaces 1213, so that the two ends of the first launcher 122 respectively form the first pressure chamber 123 and the second pressure chamber 124 corresponding to the internal pressure chambers of the first connecting end 1211 and the second connecting end 1212. The energy supply structure 3 includes a first gas supply component 31 and a second gas supply component 32. The first gas supply component 31 has two supply ports, and the two supply ports of the first gas supply component 31 are respectively connected to the sidewall interfaces 1213 of the first connecting end 1211 and the second connecting end 1212, so as to realize the respective connection with the first pressure chamber 123 and the second pressure chamber 124. The output end of the second gas supply component 32 is connected to the interior of the fixed launcher 13. When the movable launcher 12 is in the first position, the first gas supply unit 31 supplies compressed gas to the second pressure chamber 124 through the supply port, driving the first launcher 122 to be launched from the first connecting end 1211 along the trajectory of the first projectile tube 121; when the movable launcher 12 is in the second position, the first gas supply unit 31 supplies compressed gas to the first pressure chamber 123 through the supply port, driving the first launcher 122 to be launched from the second connecting end 1212 along the trajectory of the first projectile tube 121; at the same time, the second gas supply unit 32 supplies compressed gas to the interior of the fixed launcher 13, driving the first launcher 122 and the second launcher 132 to be launched synchronously along the trajectories of the first projectile tube 121 and the second projectile tube 131.

[0028] Specifically, please refer to Figure 3 and Figure 4In this embodiment, the first gas supply component 31 includes a first gas pump 311, a first connecting pipe 312, two branch pipes 313 and two first valves 314. The output end of the first gas pump 311 is connected to one end of the two branch pipes 313 through the first connecting pipe 312. The other ends of the two branch pipes 313 are respectively connected to the side wall interface 1213 of the first connecting end 1211 and the second connecting end 1212. The two first valves 314 are respectively disposed on the two branch pipes 313 and are used to control the on / off state of the two branch pipes 313. Compressed gas is supplied to the two branch pipes 313 by the first air pump 311. When the movable launcher 12 is in the first position, the first valve 314 on the branch pipe 313 connected to the second connection end 1212 is opened and closed, allowing compressed gas to enter the second pressure chamber 124 and driving the first launcher 122 to be launched from the first connection end 1211 along the trajectory of the first projectile tube 121. When the movable launcher 12 is in the second position, the first valve 314 on the branch pipe 313 connected to the first connection end 1211 is opened and closed, allowing compressed gas to enter the first pressure chamber 123 and driving the first launcher 122 to be launched from the second connection end 1212 along the trajectory of the first projectile tube 121. The second gas supply unit 32 includes a second air pump 321, a second connecting pipe 322, and a second valve 323. The output end of the second air pump 321 is connected to the top pressure chamber of the second projectile tube 131 through the second connecting pipe 322. The top of the second projectile tube 131 is fixedly mounted on the main body 11, and the mounting position of the second launcher 132 is arranged inside the bottom end. The second valve 323 is provided on the second connecting pipe 322 and is used to control the opening and closing of the second connecting pipe 322. Compressed gas is supplied to the interior of the second projectile tube 131 by the second air pump 321, and the second valve 323 is opened to allow the compressed gas to enter the interior of the second projectile tube 131, driving the second launcher 132 to be launched along the trajectory of the second projectile tube 131.

[0029] It should be noted that in this embodiment, the rotary drive component 22 can be a motor, an electric shaft, or a manual knob, as long as it can achieve the rotational drive of the mounting base 21 relative to the main body 11. When the rotary drive component 22 is a motor or an electric shaft, it is connected to the control system through a sensor. The control system can control the start, stop, and rotation angle of the motor or electric shaft according to a preset program or command, thereby precisely controlling the switching of the movable launcher 12 between the first position and the second position. When the rotary drive component 22 is a manual knob, the manual knob is provided with a locking structure corresponding to both the first and second positions of the movable launcher 12. By manually rotating the manual knob to the locking structure, the movable launcher 12 can be fixed between the first and second positions.

[0030] To ensure the safety of the experiment, other possible embodiments also provide some safety protection measures. For example, a locking mechanism is provided between the rotary drive 22 and the mounting base 21. When the movable launcher 12 is switched into position, the locking mechanism can automatically or manually lock the mounting base 21 in the current position to prevent the position of the movable launcher 12 from changing due to misoperation or external interference. The locking mechanism can be a mechanical locking device, an electromagnetic lock, or a pneumatic lock, etc., and the mounting base 21 is locked by means of extension, attraction, or locking of the locking element. When the movable launcher 12 is switched to the first position or the second position, the locking mechanism is activated, and the locking element extends, attracts, or locks between the mounting base 21 and the main body 11, fixing the movable launcher 12 in the current position.

[0031] Of course, in other possible embodiments, the energy supply structure 3 and the drive structure 2 are not limited to this and can also take other forms. For example, the energy supply structure 3 can also supply energy and drive the emitter through a pneumatic cylinder, a hydraulic cylinder, or an electromagnetic drive. The drive structure 2 can also use sliding, linear drive, or other methods to switch the movable emitter 12 between the first position and the second position.

[0032] To achieve distance adjustment between the active launcher 12 and the fixed launcher 13 in parallel launch mode, please refer to... Figure 3 In some possible embodiments, the parallel-launching mechanism further includes a position adjustment structure 4. The position adjustment structure 4 includes a fixed base 41 and a displacement drive 42. The fixed base 41 is mounted on the main body 11 and corresponds to the position of the movable launcher 12 in parallel mode. When the movable launcher 12 moves to the first position, one end of the first projectile tube 121 can partially extend into the fixed base 41 and connect to it. The displacement drive 42 is horizontally mounted on the main body 11, and its driving end is connected to the fixed base 41 to drive the fixed base 41 to move relative to the corresponding fixed launcher 13, thereby driving the movable launcher 12 to move relative to the fixed launcher 13, thus adjusting the relative distance between the movable launcher 12 and the fixed launcher 13 in parallel launch mode. The displacement drive 42 can be driven by an electric push rod, a pneumatic cylinder, or a hydraulic cylinder, etc., and its driving stroke can be precisely controlled by a preset program or command of the control system to achieve precise adjustment of the distance between the movable launcher 12 and the fixed launcher 13.

[0033] Furthermore, when the distance between the movable launcher 12 and the fixed launcher 13 is adjusted in parallel firing mode, the fixed base 41 connected to the first projectile tube 121 will move under the drive of the displacement drive 42. To ensure the stability of the first projectile tube 121 during the adjustment process, please refer to [link to relevant documentation]. Figure 3In some possible embodiments, a telescopic member 23 is provided between the mounting base 21 and the rotary drive member 22. The telescopic member 23 includes a slide rod 231, a sliding sleeve 232, and a spring 233. One end of the slide rod 231 is fixedly connected to the mounting base 21. The sliding sleeve 232 is fitted onto the slide rod 231 and fixedly connected to the rotary drive member 22. The spring 233 is disposed inside the sliding sleeve 232 and connects the sliding sleeve 232 and the slide rod 231. In parallel mode, when the first projectile tube 121 and the second projectile tube 131 are set to the closest distance, the spring 233 and the displacement drive member 42 are in their initial positions. At this time, the spring 233 will apply a certain contraction force to retract the slide rod 231 into the sliding sleeve 232, so as to ensure that the movable launcher 12 remains stable when switching from the first position to the second position. When the displacement drive 42 is activated and drives the fixed base 41 to move, causing the first projectile tube 121 to move away from the second projectile tube 131, the slide rod 231 will slide within the sliding sleeve 232, and the spring 233 will be stretched. The sliding of the slide rod 231 allows the mounting base 21 to move with the first projectile tube 121, ensuring the stability of the first projectile tube 121 during movement. When the movable launcher 12 needs to switch to the second position, the second connecting end 1212 of the first projectile tube 121 disengages from the fixed base 41. At this time, under the contraction force of the spring 233, the first projectile tube 121 can return to its initial state, ensuring that the first projectile tube 121 and the second projectile tube 131 can be smoothly connected and enter the series launch mode.

[0034] Furthermore, each mounting base 41 is equipped with a locking and sealing mechanism. For example, multiple sealing plates can be arranged opposite each other. A cylinder or other driving component can be used to move these sealing plates closer together or further apart. When the first missile tube 121 of the movable launcher 12 extends into the mounting base 41, the multiple sealing plates approach each other and adhere to the outer wall of the first missile tube 121, forming a sealed structure to prevent gas leakage and ensure the stability and safety of the launch test. Understandably, to ensure the stability and sealed connection of the first missile tube 121 and the second missile tube 131 in the tandem launch mode, a similar locking and sealing mechanism can also be provided on the mounting base 21. Its principle is the same as the locking and sealing mechanism on the mounting base 41, and will not be elaborated upon here.

[0035] Please see Figures 4 to 6To further enhance the flexibility and stability of the launching mechanism, in this embodiment, the series-parallel launching mechanism also includes a locking mechanism 5. The locking mechanism 5 includes two locking components and an adjusting component 53. The two locking structures are respectively installed on one side of the first projectile tube 121 and the second projectile tube 131, and each has a telescopic locking end. The telescopic locking end has a locked state connected to the first or second projectile and an unlocked state disconnected from the first or second projectile. Through the design of the locking components, the first projectile 122 and the second projectile 132 inside the first projectile tube 121 and the second projectile tube 131 can be fixed, ensuring that the projectile's fixed position is accurate and stable. The adjusting component 53 is connected to one of the locking components and is used to drive the locking component to move relative to the other locking component to adjust the distance between the first and second projectiles. In the series launching mode, the distance between the two projectiles can be adjusted by the adjusting component 53 to meet different test requirements.

[0036] In one embodiment, the two locking components are defined as a first locking component 51 and a second locking component 52, respectively. The first locking component 51 includes a first electromagnetic switch 511 and a first adjusting bracket 512. The first adjusting bracket 512 is fixed to one side of the first spring block, and the first electromagnetic switch 511 is mounted on the first adjusting bracket 512. The second locking component 52 includes a second electromagnetic switch 521 and a second adjusting bracket 522. The second adjusting bracket 522 is mounted on the main body 11 or the second spring tube 131, and the second electromagnetic switch 521 is fixedly mounted on the second adjusting bracket 522. The adjusting component 53 is driven by an electric push rod, a pneumatic cylinder, or a threaded rod, etc., and is mounted on the first adjusting bracket 512. Its driving end is connected to the first electromagnetic switch 511, which can drive the first electromagnetic switch 511 to move relative to the second electromagnetic switch 521, thereby adjusting the distance between the first launcher and the second launcher. When both the first electromagnetic switch 511 and the second electromagnetic switch 521 are energized, their telescopic locking ends will extend and lock the corresponding first or second launcher, ensuring the stable fixation of the launcher before launch. When the spacing needs to be adjusted, the control system can activate the adjustment component 53, driving the first electromagnetic switch 511 to move relative to the second electromagnetic switch 521. After moving to the preset position, the spacing adjustment is completed to adapt to different test requirements. When launching the projectile, the corresponding air pump, valve, and electromagnetic switch need to be turned on. The air pump compresses the gas and injects it into the projectile tube, driving the launcher to be launched at high speed along the trajectory.

[0037] Furthermore, in some possible embodiments, a groove 1214 is provided on one side of the first projectile tube 121, and a sealing slide plate 1215 is slidably disposed on the groove 1214. The drive switch of the first electromagnetic switch 511 passes through the sealing slide plate 1215 and is connected to the first launcher 122. When the first electromagnetic switch 511 moves to adjust the position of the first launcher 122, the sealing slide plate 1215 can slide along the groove 1214 to ensure the sealing state of the first pressure chamber 123 and the second pressure chamber 124.

[0038] Of course, in other possible embodiments, the locking mechanism 5 can also take other forms, such as mechanical locking devices, pneumatic locks or manual locking knobs, as long as it can achieve stable fixation of the launcher before launch and unlocking of the launcher when needed.

[0039] In some possible embodiments, the series-parallel launching mechanism also includes a control module connected to the energy supply structure 3. The control module is used to synchronously or independently control the triggering timing and launching energy of the fixed launcher 13 and the movable launcher 12 via the energy supply structure 3. The control module can precisely control the energy supply structure 3 to provide launching energy to the fixed launcher 13 and the movable launcher 12, and control the triggering timing of the launchers, according to preset test parameters or instructions. Simultaneously, the control module is also electrically connected to the locking mechanism 5, which can control the electromagnetic switch to fix the launchers, and can also control the adjustment component 53 to adjust the distance between the first and second launchers in series mode.

[0040] In tandem launch mode, the control module can synchronously trigger the launch of the fixed launcher 13 and the movable launcher 12, causing the launchers to enter the water simultaneously to simulate a scenario of multiple launchers entering the water in parallel. In parallel launch mode, the control module can independently control the launch timing of the fixed launcher 13 and the movable launcher 12, causing the fixed launcher 13 and the movable launcher 12 to enter the water separately to simulate a scenario of multiple launchers entering the water in series.

[0041] Secondly, embodiments of the present invention also provide a test apparatus, including a series-parallel transmission mechanism as described in any of the above embodiments.

[0042] Please see Figure 7 In some possible embodiments, the test apparatus further includes a water tank 6, a light source 7, and a camera 8. The light source 7 and camera 8 are respectively installed on both sides of the water tank 6. The main body 11 is mounted on the water tank 6. The water tank 6 contains water for receiving the transmitter, and a buffer pad 9 is installed at its bottom. During the test, the camera 8 is used to record the trajectory of the transmitter and its entry into the water. The light source 7 can be an LED light, a halogen lamp, or a reflector, etc., used to provide illumination and ensure the clarity of the captured images.

[0043] To better understand this invention, the following is combined with... Figures 1 to 7 The technical solution of the present invention is described in detail as follows: During the tandem test, the fixed launcher 13 and the movable launcher 12 are first arranged in series via the drive structure 2. At this time, the first launcher 122 and the second launcher 132 are arranged in a front-to-back configuration. Then, the launch time of the first launcher 122 and the second launcher 132 is set by the control module to ensure that they are launched into the water sequentially according to a predetermined time sequence. After the first launcher 122 is launched into the water, the second launcher 132 immediately follows, realizing the tandem test. During the test, the camera 8 records the movement trajectory of the launchers and the water entry process, and the light source 7 provides illumination to ensure the clarity of the captured images.

[0044] During parallel testing, the fixed launcher 13 and the movable launcher 12 are first arranged in parallel using the drive structure 2. At this point, the first launcher 122 and the second launcher 132 can simultaneously conduct independent water entry tests. The control module controls the launch time of the first launcher 122 and the second launcher 132 respectively, ensuring that the launchers are launched into the water simultaneously. In parallel testing mode, the interaction and hydrodynamic characteristics of the first launcher 122 and the second launcher 132 when they enter the water simultaneously can be studied, providing strong experimental support for research in related fields.

[0045] This invention, by setting up a launching unit 1, a driving structure 2, and an energy supply structure 3, controls the position of the movable launching element 12 through the driving structure 2, realizing rapid switching between parallel (parallel arrangement) and series (coaxial arrangement) launching modes. It can easily switch between series and parallel water entry test modes, effectively solving the problem of the single test mode of traditional devices, greatly expanding the application range and flexibility of the test, and optimizing space utilization. The energy supply structure 3 is used to supply energy to the fixed and movable launching elements 12, ensuring the energy synchronization and stability of the dual launching units, and improving launching efficiency and reliability.
