Description

Technical Field

[0001] This invention relates to the field of equipment deployment technology, specifically to a disc-shaped underwater deployer, a deployer launching device, and a deployer launching assembly. Background Technology

[0002] When surface ships conduct underwater emergency rescue, rapid underwater obstacle removal, or rapid underwater structural demolition, they need to use underwater delivery vehicles to quickly deploy supplies or payloads to specific underwater locations. The design of these delivery vehicles is generally based on stable operation in air or water media, with their noses typically designed as either aerodynamic or hydrodynamic shapes—that is, conventional cylindrical rotating bodies with pointed noses. However, at higher delivery speeds, due to changes in the properties of the medium, cylindrical rotating bodies with pointed noses are prone to "skipping" on the water surface when entering the water at small angles, failing to follow a predetermined trajectory. Alternatively, high-speed entry can cause cavitation, leading to temporary "failure" of the control system and resulting in an unstable, skewed underwater trajectory.

[0003] To address the instability issue of high-speed water entry in cylindrical rotating pointed-tip dispensers, a disc-shaped dispenser has been developed. This disc-shaped dispenser can achieve stable water entry at high speeds and small angles. The condition for stable water entry is that the dispenser must simultaneously undergo high-speed translational motion and high-speed rotation around its central axis. To achieve this motion, Chinese invention patent CN113267099B discloses a toothed disc-shaped rapid underwater dispenser and a corresponding launch tube. The dispenser includes a disc-shaped body, with the thickness of the edge portion being less than the thickness of the central region. The disc-shaped body has evenly distributed teeth around its circumference. The launch tube's launch chamber inner wall is equipped with a rack. The blade and the eccentric teeth can mesh. When used for underwater deployment, the launching device aims at the target according to the control system command. The launcher is loaded into the rear of the launching tube by the conveying device, or the tube and the launcher can be pre-installed. After installation, the launcher is in the ready position in the launching chamber. Propellant gas or other high-pressure gas is introduced into the bottom of the launching device. The gas enters the rear of the ready position. The gas and high-pressure gas expand and do work, propelling the launcher forward. Because the blade-shaped eccentric teeth of the launcher mesh with the internal teeth of the launching chamber, the launcher moves forward in the launching chamber while rotating around its axis. After the launcher exits the tube, it moves forward along a predetermined trajectory while rotating around its axis. The high-speed rotation can ensure the trajectory stability of the launcher during the gas-liquid medium process.

[0004] The aforementioned structure, which uses a gear and rack mechanism to achieve the spin of the dispenser, has a high speed of translation along the launch chamber. The teeth on the dispenser mesh with the rack on the inner wall of the launch chamber during the high-speed translation of the dispenser. The teeth on the dispenser and the teeth on the rack will impact and collide, and jamming can easily occur. If the dispenser gets stuck in the launch chamber and cannot get out, the pressure in the space behind the dispenser in the launch chamber will rise sharply. Excessive pressure can damage the launch device, and in severe cases, it can cause an explosion. Therefore, it is not safe and reliable to use. Summary of the Invention

[0005] The purpose of this invention is to provide a disc-shaped underwater dispenser to solve the problem that current dispensers are prone to getting stuck in the launch cavity, resulting in low safety. The purpose of this invention is also to provide a matching dispenser launching device and a dispenser launching assembly including the disc-shaped underwater dispenser and the dispenser launching device.

[0006] The technical solution of the disc-shaped underwater launcher of the present invention is as follows:

[0007] The disc-shaped underwater launcher includes a disc-shaped body. The center of the disc-shaped body has an axially penetrating airflow channel. A turbine structure is provided inside the airflow channel. The turbine structure includes fan blades fixed to the disc-shaped body. The fan blades are used to allow airflow to pass through before the launcher is launched, so as to drive the disc-shaped body to pre-rotate. The outer peripheral surface of the disc-shaped body is a smooth surface for cooperating with the smooth cavity wall of the launch chamber of the launch device.

[0008] Beneficial effects: This invention improves upon existing disc-shaped underwater launchers by creating an axially penetrating airflow channel at the center of the disc-shaped body and incorporating a turbine structure within the channel. As airflow travels from one side of the disc-shaped body through the channel to the other, the turbine blades work in conjunction with the airflow to generate a rotational force on the blades, which are fixed to the disc-shaped body. This allows the entire launcher to spin. The high-speed airflow combined with the turbine structure enables the launcher to rotate around its own axis. Compared to existing launchers, this design eliminates the need for a toothed structure, allowing for a smoother outer contour. During launch, the launcher's translational motion within the launch chamber is less prone to jamming, promoting safe and reliable operation.

[0009] Furthermore, the central part of the disc-shaped body is provided with a central hole, and a central shaft is provided inside the central hole. One end of the fan blade is fixed to the wall of the central hole, and the other end is fixed to the central shaft.

[0010] Beneficial effects: By setting a central shaft, each fan blade can be fixed together on the central shaft and then fixed as a whole in the central hole, which facilitates the fixing operation and helps to ensure manufacturing precision.

[0011] Furthermore, the thickness of the central part of the disc-shaped body is greater than the thickness of the edge part, and the central part has a plane, on which the airflow channel is set.

[0012] Beneficial effects: It makes the two sides of the disc-shaped body have planes, which facilitates the positioning of the turbine structure and makes it easier to guide and fit with the inner wall of the launch cavity.

[0013] The technical solution of the dispenser launching device of the present invention is as follows:

[0014] The launcher includes a launch chamber with an outlet for launching a disc-shaped underwater launcher. The launch chamber has a preparatory position for accommodating the disc-shaped underwater launcher before launch. On opposite sides of the preparatory position of the launch chamber are a first air inlet and a first air outlet, respectively. The first air inlet and the first air outlet correspond to the turbine structure in the airflow channel of the disc-shaped body on both axial sides of the disc-shaped body of the underwater launcher, so that the airflow enters from the first air inlet, passes through the fan blades of the turbine structure fixed to the disc-shaped body, and exits from the first air outlet, thereby realizing the pre-rotation of the disc-shaped body. The launch chamber has a smooth cavity wall for cooperating with the smooth outer peripheral surface of the disc-shaped body.

[0015] Beneficial effects: This invention improves upon existing launcher devices by setting a first air inlet and a first air outlet at the preparatory position of the disc-shaped underwater launcher. The first air inlet and the second air outlet are positioned on opposite sides of the disc-shaped underwater launcher's axial direction, corresponding to the turbine structure within its airflow channel. This allows airflow to enter the airflow channel through the first air inlet, pass through the turbine blades, and exit through the first air outlet. The turbine blades work in conjunction with the airflow, generating a rotational force on the fixed blades, causing the entire launcher to spin and launch. The high-speed airflow entering the launch chamber, combined with the launcher's turbine structure, allows the launcher to rotate around its own axis. Compared to existing launch chambers, this launcher does not require a rack and pinion structure. During launch, the launcher's translational movement within the launch chamber is less prone to jamming, promoting safe and reliable operation.

[0016] Furthermore, a second air inlet is provided on the side of the launch chamber wall away from the outlet in the preparatory position. The second air inlet is used to allow the airflow that propels the disc-shaped underwater launcher to enter.

[0017] Beneficial effect: The second air inlet facilitates the arrangement of the airflow generating device.

[0018] Furthermore, the launching device also includes a discharge cavity, with the first air outlet and the second air inlet both connected to the discharge cavity. A plug is provided inside the discharge cavity, and the plug is equipped with a drive mechanism for moving it. The plug has a first position that blocks the second air inlet and a second position that opens the second air inlet during its movement stroke.

[0019] Beneficial effects: When the second air inlet is blocked by the plug, the airflow enters the exhaust chamber through the first air inlet, the fan blades of the turbine structure, and the first air outlet. The disc-shaped underwater launcher spins. Then the plug is moved to open the second air inlet, allowing the airflow that entered the exhaust chamber to enter the launch chamber through the second air inlet. This airflow then propels the disc-shaped underwater launcher forward from behind, thus launching it. In this way, the same power source can be used to complete the spin and translation motion of the disc-shaped underwater launcher.

[0020] Furthermore, the exhaust cavity is provided with an exhaust port that communicates with the external space of the launching device, and the plug blocks the exhaust port when in the second position.

[0021] Beneficial effects: When the second air inlet is blocked by the plug, the exhaust port is open, and the airflow can directly reach the outside, which is conducive to the smooth passage of airflow and enables the disc-shaped underwater launcher to reach a higher speed; when the exhaust port is blocked by the plug, the second air inlet is open, ensuring that the airflow smoothly enters the launch chamber to drive the disc-shaped underwater launcher.

[0022] Furthermore, the exhaust port is formed by a strip-shaped hole.

[0023] Beneficial effect: It can make the shape of the exhaust port and the second air inlet correspond, which makes it easier to seal the corresponding port when the position of the plug is switched.

[0024] Furthermore, the launching device also includes a gunpowder chamber containing gunpowder, and the gunpowder chamber is connected to the first air inlet.

[0025] Beneficial effects: The high-speed gas generated by gunpowder ignition can enable the disc-shaped underwater launcher to quickly achieve a high rotation speed, and it also helps to simplify the structure of the launching device.

[0026] The technical solution of the dispenser launching component of the present invention is as follows:

[0027] The launcher assembly includes a launcher device and a disc-shaped underwater launcher. The disc-shaped underwater launcher includes a disc-shaped body with an axially penetrating airflow channel at its center. A turbine structure is located within the airflow channel, including fan blades fixed to the disc-shaped body. The fan blades are used to supply airflow before launch to pre-rotate the disc-shaped body. The outer circumferential surface of the disc-shaped body is a smooth surface designed to mate with the smooth cavity wall of the launcher device's launch chamber. The launcher device includes a launch chamber with an outlet for launching the disc-shaped underwater launcher. The cavity is provided with a preparatory position for accommodating the disc-shaped underwater launcher before launch. On the opposite sides of the cavity wall at the preparatory position of the launch cavity, there are respectively a first air inlet and a first air outlet. The first air inlet and the first air outlet are respectively used to correspond to the turbine structure in the airflow channel of the disc-shaped body on both sides of the disc-shaped body of the underwater launcher, so that the airflow enters from the first air inlet and exits from the first air outlet after passing through the fan blades of the turbine structure that are fixed to the disc-shaped body, thereby realizing the pre-rotation of the disc-shaped body. The launch cavity has a smooth cavity wall for cooperating with the smooth outer peripheral surface of the disc-shaped body.

[0028] Beneficial effects: By setting a first air inlet and a first air outlet at the preparatory position of the disc-shaped underwater launcher, and positioning the first air inlet and the second air outlet on opposite sides of the axial direction of the disc-shaped underwater launcher corresponding to the turbine structure within its airflow channel, airflow can enter the airflow channel from the first air inlet, pass through the blades of the turbine structure, and then exit from the first air outlet. The turbine blades work in conjunction with the airflow, generating a rotational force on the fixed blades, causing the entire launcher to spin and launch. The high-speed airflow entering the launch chamber, combined with the turbine structure of the launcher, allows the launcher to rotate around its own axis. Compared to existing launch chambers, this launch device does not require a rack and pinion structure. During launch, the translational motion of the launcher within the launch chamber is less prone to jamming, promoting safe and reliable operation.

[0029] Furthermore, the central part of the disc-shaped body is provided with a central hole, and a central shaft is provided inside the central hole. One end of the fan blade is fixed to the wall of the central hole, and the other end is fixed to the central shaft.

[0030] Beneficial effects: By setting a central shaft, each fan blade can be fixed together on the central shaft and then fixed as a whole in the central hole, which facilitates the fixing operation and helps to ensure manufacturing precision.

[0031] Furthermore, the thickness of the central part of the disc-shaped body is greater than the thickness of the edge part, and the central part has a plane, on which the airflow channel is set.

[0032] Beneficial effects: It makes the two sides of the disc-shaped body have planes, which facilitates the positioning of the turbine structure and makes it easier to guide and fit with the inner wall of the launch cavity.

[0033] Furthermore, a second air inlet is provided on the side of the launch chamber wall away from the outlet in the preparatory position. The second air inlet is used to allow the airflow that propels the disc-shaped underwater launcher to enter.

[0034] Beneficial effect: The second air inlet facilitates the arrangement of the airflow generating device.

[0035] Furthermore, the launching device also includes a discharge cavity, with the first air outlet and the second air inlet both connected to the discharge cavity. A plug is provided inside the discharge cavity, and the plug is equipped with a drive mechanism for moving it. The plug has a first position that blocks the second air inlet and a second position that opens the second air inlet during its movement stroke.

[0036] Beneficial effects: When the second air inlet is blocked by the plug, the airflow enters the exhaust chamber through the first air inlet, the fan blades of the turbine structure, and the first air outlet. The disc-shaped underwater launcher spins. Then the plug is moved to open the second air inlet, allowing the airflow that entered the exhaust chamber to enter the launch chamber through the second air inlet. This airflow then propels the disc-shaped underwater launcher forward from behind, thus launching it. In this way, the same power source can be used to complete the spin and translation motion of the disc-shaped underwater launcher.

[0037] Furthermore, the exhaust cavity is provided with an exhaust port that communicates with the external space of the launching device, and the plug blocks the exhaust port when in the second position.

[0038] Beneficial effects: When the second air inlet is blocked by the plug, the exhaust port is open, and the airflow can directly reach the outside, which is conducive to the smooth passage of airflow and enables the disc-shaped underwater launcher to reach a higher speed; when the exhaust port is blocked by the plug, the second air inlet is open, ensuring that the airflow smoothly enters the launch chamber to drive the disc-shaped underwater launcher.

[0039] Furthermore, the exhaust port is formed by a strip-shaped hole.

[0040] Beneficial effect: It can make the shape of the exhaust port and the second air inlet correspond, which makes it easier to seal the corresponding port when the position of the plug is switched.

[0041] Furthermore, the launching device also includes a gunpowder chamber containing gunpowder, and the gunpowder chamber is connected to the first air inlet.

[0042] Beneficial effects: The high-speed gas generated by gunpowder ignition can enable the disc-shaped underwater launcher to quickly achieve a high rotation speed, and it also helps to simplify the structure of the launching device. Attached Figure Description

[0049] Embodiment 1 of the disc-shaped underwater launcher of the present invention:

[0050] In this embodiment, an axially penetrating airflow channel is set in the center of the disc-shaped body, and a turbine structure is set in the airflow channel. When the airflow flows from one side of the disc-shaped body to the other side through the airflow channel, the turbine blades cooperate with the airflow to generate a rotational force on the blades. Since the blades are fixed to the disc-shaped body, the entire dispenser can rotate. The high-speed airflow combined with the turbine structure enables the dispenser to meet the requirement of rotating around its own axis. Compared with the dispensers in the prior art, such a dispenser does not need to set a toothed structure, and the outer contour can be set to be smoother. During launch, the translational process of the dispenser in the launch cavity is less likely to jam, which is conducive to safe and reliable use.

[0051] Specifically, such as Figure 1 , Figure 2 , Figure 3As shown, the disc-shaped underwater dispenser, or dispenser 1, includes a disc-shaped body. The disc-shaped body is generally disc-shaped. The thickness of the central part of the disc-shaped body is greater than that of the edge part, and the thickness gradually decreases around the periphery of the central part. The thickness direction of the disc-shaped body is consistent with the axial direction. The central part is the part close to the axis of the disc-shaped body, and the edge part is the part close to the outer circular outline. The central part of the disc-shaped body transitions to the edge part through a smooth curved surface. The smooth curved surface is part of a sphere. The smooth curved surfaces on both sides of the axial direction of the disc-shaped body transition along an arc around one periphery of the disc-shaped body. The arc transition surface is the outer peripheral surface of the disc-shaped body. The outer peripheral surface of the disc-shaped body is a smooth surface used to cooperate with the smooth cavity wall of the launch cavity of the launch device. This smooth surface is a surface without concave or convex structures, which allows the dispenser to move smoothly within the launch cavity and avoid jamming.

[0052] The central part of the disc-shaped body of the dispenser 1 has a plane 11, giving the disc-shaped body two axially opposite planes 11. A central hole is formed on the plane 11, located at the center of the dispenser 1, and runs through the axis of the disc-shaped body. The central hole forms an axially through airflow channel at the center of the disc-shaped body. A turbine structure is installed inside the central hole, including several blades 12 and a central shaft. One end of each blade 12 is fixed to the wall of the central hole, and the other end is fixed to the central shaft. The blades 12 are used to drive the disc-shaped body to rotate when the airflow passes through them. A turbine is a mechanical device that rotates by utilizing the impact or reaction force of the fluid passing through it. By passing high-speed airflow through the blades 12 of the turbine, the dispenser 1 can be driven to rotate around its own axis, satisfying the spin requirement.

[0053] Embodiment 2 of the disc-shaped underwater launcher of the present invention:

[0054] This embodiment provides a turbine structure configuration different from Embodiment 1. The difference between this embodiment and Embodiment 1 is that in Embodiment 1, each blade is fixed on a central shaft. In this embodiment, however, there is no central shaft, and the corresponding ends of each blade are directly fixed together.

[0055] Embodiment 3 of the disc-shaped underwater launcher of the present invention:

[0056] This embodiment provides a different disc-shaped body configuration than Embodiment 1. The difference between this embodiment and Embodiment 1 is that the central part of the disc-shaped body in Embodiment 1 has a plane, and the airflow channel is located on the plane. In this embodiment, however, there is no plane, and both axial sides of the disc-shaped body are conical surfaces, with the airflow channel located at the center of the conical surface.

[0057] Embodiment 1 of the dispenser launching device of the present invention:

[0058] like Figure 4 and Figure 5As shown, the launcher includes a launch tube 2, a propellant chamber 3, and a guide chamber 4. Both the propellant chamber 3 and the guide chamber 4 are located at the rear end of the launch tube 2. The inner cavity of the launch tube 2 forms the launch chamber 21, and the front end of the launch tube 2 forms the outlet of the launch chamber 21 for launching the disc-shaped underwater launcher. The launch chamber 21 has a preparatory position for accommodating the disc-shaped underwater launcher (launcher 1) before launch. Before launch, the disc-shaped underwater launcher is in the preparatory position, and the axis of the launcher 1 is approximately vertical. The preparatory position is located at the rear of the launch chamber 21. The launch chamber 21 is shaped to match the launcher 1, allowing the launcher 1 to translate and rotate within the launch chamber 21. The walls of the launch chamber guide the translation of the launcher 1.

[0059] The launch chamber 21 has a first air inlet 22 and a first air outlet 23 on opposite sides of its preparatory position. Both the first air inlet 22 and the first air outlet 23 are formed by circular through holes on their respective side walls, and the diameter of the through holes is not less than the inner diameter of the airflow channel of the dispenser 1. The first air inlet 22 and the first air outlet 23 are respectively located on both axial sides of the disc-shaped body of the dispenser 1 and correspond to the turbine structure in the airflow channel of the disc-shaped body, so that the airflow enters from the first air inlet 22, passes through the fan blades of the turbine structure fixed to the disc-shaped body, and exits from the first air outlet 23.

[0060] The gunpowder chamber 3 is located below the launch tube 2. The gunpowder chamber 3 is a cylindrical cavity, and its inner cavity forms the gunpowder cavity 31, which contains gunpowder. The gunpowder cavity 31 is connected to the first air inlet 22. The high-speed gas generated by the ignition of the gunpowder can rush through the first air inlet 22 towards the turbine blades of the dispenser 1, enabling the disc-shaped underwater dispenser to quickly achieve a high rotational speed and simplifying the structure of the launching device. The gap between the cavity wall of the launch chamber 21 and the dispenser 1 is very small, and most of the airflow generated by the ignition of the gunpowder flows through the turbine structure. Furthermore, under the action of the high-speed airflow, the dispenser 1 will automatically return to a state where the airflow channel is directly aligned with the first air inlet 22. The airflow pushes the fan blades, which counteracts the gravity of the dispenser 1, causing the dispenser 1 to be in a pneumatic suspension state. The dispenser 1 can spin in place in the preparatory position. Even if the dispenser 1 comes into contact with the inner wall of the launching cavity 21, the spin of the dispenser 1 will cause the frictional forces in different directions to cancel each other out, thus maintaining the position of the dispenser 1.

[0061] The guide chamber 4 is located above the launch tube 2. The front of the guide chamber 4 is arc-shaped and the rear is rectangular. The inner cavity of the guide chamber 4 forms the guide cavity 42. A second air inlet 24 is provided on the side of the launch cavity 21 away from the front outlet in the preparatory position. The second air inlet 24 is used to enter the airflow that propels the disc-shaped underwater launcher. The second air inlet 24 is located behind the first air outlet 23. Both the first air outlet 23 and the second air inlet 24 are connected to the guide cavity 42. The guide cavity 42 is provided with an exhaust port 41 that communicates with the external space of the launch device. The exhaust port 41 is located on the side of the guide cavity 42 away from the launch tube 2. The exhaust port 41 corresponds to the position of the second air inlet 24. Both the exhaust port 41 and the second air inlet 24 are formed by strip-shaped holes. The extension direction of the strip-shaped holes is perpendicular to the axial direction of the launcher 1. A plug 5 is provided inside the exhaust guide cavity 42. The plug 5 can move between the exhaust port 41 and the second air inlet 24. The plug 5 is equipped with a drive mechanism for driving its movement, which can be an electric cylinder or a pneumatic cylinder. The plug 5 has a first position that blocks the second air inlet 24 and a second position that opens the second air inlet 24 during its movement stroke. When the plug 5 is in the second position, it blocks the exhaust port 41. That is, the plug 5 can switch between the position of blocking the second air inlet 24 and the position of blocking the exhaust port 41.

[0062] When the plug 5 blocks the second air inlet 24, the exhaust port 41 opens, and the airflow enters the exhaust chamber 42 through the first air inlet 22, the turbine blades, and the first air outlet 23, and then directly to the outside. The disc-shaped underwater launcher spins, that is, it rotates around its own axis, and the airflow passes smoothly, allowing the disc-shaped underwater launcher to reach a high speed. The launch chamber 21 is equipped with a speed measuring device for detecting the speed of the disc-shaped underwater launcher. The speed measuring device can be a photoelectric speed measuring device. After the speed reaches the required level, the plug 5 is moved to open the second air inlet 24 and block the exhaust port 41, so that the airflow entering the exhaust chamber 42 enters the space behind the disc-shaped underwater launcher in the launch chamber 21 through the second air inlet 24, and pushes the disc-shaped underwater launcher forward, thus launching it. In this way, the same power source can be used to complete the spin + translational motion process of the disc-shaped underwater launcher, ensuring the stability of the disc-shaped launcher 1 when it enters the water.

[0063] At launch, the dispenser 1 is placed in the ready position, and the second air inlet 24 is initially blocked. After the propellant is ignited, high-speed gas is generated. The high-speed gas flows through and drives the turbine to rotate and accelerate, which in turn drives the entire dispenser 1 to rotate and accelerate. The gas passing through the turbine enters the exhaust chamber 4 and is then discharged into the atmosphere through the exhaust port 41. The speed measuring device transmits a signal to the corresponding controller. When the dispenser 1 reaches the required rotational speed, the controller issues a command, and the drive mechanism drives the plug 5 to move in the exhaust chamber 4, opening the second air inlet 24 while simultaneously blocking the exhaust port 41. At this time, the high-pressure gas that enters the exhaust chamber 4 through the turbine enters the rear of the dispenser 1 through the second air inlet 24, pushing the dispenser 1 forward and accelerating until it is launched from the launch device. At this time, the dispenser 1 not only obtains a high rotational speed around its own axis but also a high translational speed.

[0064] Embodiment 2 of the dispenser launching device of the present invention:

[0065] This embodiment provides a different launch chamber configuration than Embodiment 1. The difference lies in that, in Embodiment 1, the launch chamber wall has a second air inlet on the side furthest from the outlet at the preparatory position. This second air inlet is used to introduce the airflow that propels the disc-shaped underwater launcher. In this embodiment, however, there is no second air inlet, and the launching propellant is directly installed behind the preparatory position of the launch chamber.

[0066] Embodiment 3 of the dispenser launching device of the present invention:

[0067] This embodiment provides a different configuration from Embodiment 1. The difference between this embodiment and Embodiment 1 is that the launching device in Embodiment 1 also includes a guide cavity, and both the first air outlet and the second air inlet are connected to the guide cavity. In this embodiment, however, the guide cavity is not provided. Instead, a gunpowder chamber is provided at the second air inlet. The two gunpowder chambers respectively provide the airflow that drives the dispenser to spin and the airflow that drives the dispenser to translate.

[0068] Embodiment 4 of the dispenser launching device of the present invention:

[0069] This embodiment provides a different exhaust cavity configuration than Embodiment 1. The difference between this embodiment and Embodiment 1 is that the exhaust cavity in Embodiment 1 has an exhaust port communicating with the external space of the launching device, and the plug blocks the exhaust port when in the second position. In this embodiment, the exhaust cavity does not have an exhaust port, and the internal space of the exhaust cavity is larger, so the gas passing through the turbine is temporarily stored in the exhaust cavity.

[0070] Embodiment 5 of the dispenser launching device of the present invention:

[0071] This embodiment provides a different exhaust port configuration than Embodiment 1. The difference between this embodiment and Embodiment 1 is that the exhaust port in Embodiment 1 is formed by a strip-shaped hole, while in this embodiment, the exhaust port is formed by a circular hole.

[0072] Embodiment 6 of the dispenser launching device of the present invention:

[0073] This embodiment provides a different launching device configuration than Embodiment 1. The difference between this embodiment and Embodiment 1 is that, in Embodiment 1, the launching device includes a gunpowder chamber containing gunpowder, and the gunpowder chamber is connected to a first air inlet. In this embodiment, however, the first air inlet is connected to a high-pressure gas source, which supplies airflow to drive the launcher to rotate.

[0074] An embodiment of the dispenser launching component in this invention:

[0075] The dispenser launching assembly includes a disc-shaped underwater dispenser and a dispenser launching device. The disc-shaped underwater dispenser in this embodiment is the same as the disc-shaped underwater dispenser in any of the embodiments 1-3 of the above-mentioned disc-shaped underwater dispenser. The dispenser launching device in this embodiment is the same as the dispenser launching device in any of the embodiments 1-6 of the above-mentioned dispenser launching device, and will not be described again here.

[0076] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features.

2. The dispenser launching device according to claim 1, characterized in that, The exhaust port is formed by a strip-shaped hole.

3. The dispenser launching device according to claim 1 or 2, characterized in that, The launching device also includes a gunpowder chamber containing gunpowder, which is connected to the first air inlet.

4. A dispenser launching component, characterized in that, The device includes a disc-shaped underwater launcher and a launch device. The launch device includes a launch chamber and a guide chamber. The launch chamber has an outlet for launching the disc-shaped underwater launcher. A preparatory position for accommodating the launcher before launch is provided within the launch chamber. A first air inlet and a first air outlet are respectively provided on opposite sides of the preparatory position of the launch chamber. The first air inlet and the first air outlet correspond to turbine structures within an axially penetrating airflow channel on either side of the disc-shaped body of the launcher, respectively. This allows airflow to enter through the first air inlet, pass through the turbine structure's blades fixed to the disc-shaped body, and exit through the first air outlet, where the airflow's pushing action on the blades cancels out the impact. The dispenser is subjected to gravity to achieve a pneumatic suspension, enabling the disc-shaped body to pre-rotate in place at the ready position. The launching cavity has a smooth cavity wall that mates with the smooth outer circumferential surface of the disc-shaped body. A second air inlet is provided on the cavity wall of the launching cavity on the side away from the outlet at the ready position. Both the first air outlet and the second air inlet are connected to the exhaust guide cavity. The exhaust guide cavity has an exhaust port that communicates with the external space of the launching device. A plug is provided in the exhaust guide cavity. The plug is equipped with a mechanism for driving its movement. The plug has a first position that blocks the second air inlet during its movement stroke and a second position that opens the second air inlet and blocks the exhaust port after the dispenser reaches the required rotation speed, allowing airflow to enter the rear of the dispenser for launching.

5. The dispenser launching assembly according to claim 4, characterized in that, The disc-shaped body has a central hole at its center, which forms an airflow channel. A central shaft is located inside the central hole. One end of the fan blade is fixed to the wall of the central hole, and the other end is fixed to the central shaft.
