Description

Technical Field

[0001] This application relates to the field of underwater vehicle equipment technology, and more specifically, to a jettisoning device and an underwater vehicle. Background Technology

[0002] Currently, underwater vehicles such as underwater gliders are widely used in fields such as ocean observation, environmental monitoring, and military reconnaissance. Underwater gliders achieve zigzag gliding motion by adjusting buoyancy and attitude. When encountering strong ocean currents, equipment malfunctions, or insufficient energy, underwater gliders need to surface quickly. At this time, a jettison device is used to jettison some weight, making the glider's gravity less than its buoyancy, thus achieving rapid ascent. However, existing jettison devices for underwater vehicles suffer from problems such as complex structure, cumbersome jettisoning process, and long jettisoning time due to their non-modular design and different jettisoning methods. Moreover, existing jettison devices require dynamic sealing, which is inconvenient for installation and maintenance, and also hinders future repair and replacement. Summary of the Invention

[0003] This application aims to at least address the technical problems in the related art, such as the complex structure, cumbersome jettisoning process, and long jettisoning time of the jettisoning device of underwater vehicles due to its non-modular design, as well as the fact that the existing jettisoning device requires dynamic sealing, which makes it inconvenient to install and maintain.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows: In a first aspect, this application provides a load-throwing device, comprising: a mounting cylinder and an isolation cover, the mounting cylinder and the isolation cover being fixedly connected and enclosing to form a mounting cavity; a driving component disposed within the mounting cavity, with a first magnetic pole piece provided on the outer peripheral surface of the driving component located on one side of the isolation cover; a driven component sleeved on the isolation cover, the driving component and the driven component being rotatably connected, the driven component having a second magnetic pole piece inside that is opposite to the first magnetic pole piece; a mounting component, one end of the mounting component being connected to the driven component, and the other end having an annular groove structure, with a notch on one side of the annular groove structure; and a load-throwing component, one end of the load-throwing component having a ball head structure, the ball head structure being engaged within the annular groove structure through the notch and being able to slide along the annular groove structure; wherein, the driving component drives the driven component to rotate through the magnetic coupling between the first magnetic pole piece and the second magnetic pole piece, so that the ball head structure can disengage from the notch, thereby achieving load throwing.

[0005] The jettison device provided in this application adopts a modular design. The entire jettison device can be integrated as a separate system into the fuselage of an underwater vehicle, such as an underwater glider. The connection method is simple, facilitating later maintenance and replacement. Furthermore, the jettison device uses magnetic coupling to transmit torque. By rationally arranging the positions of the first and second magnetic pole pieces, the magnetic coupling between the pole pieces can transmit a larger torque, while avoiding problems such as high power consumption due to dynamic seals and water leakage caused by easy wear of the sealing rings. In addition, while ensuring torque, the jettison device of this application transmits power through a direct connection between the drive component and the driven component, eliminating the intermediate transmission mechanism. This results in high space utilization, light weight, and a compact structure, making it easy to install on the fuselage of an underwater vehicle, such as an underwater glider, and also facilitating maintenance. The jettison device provided in this application solves the technical problems of existing underwater vehicle jettison devices, such as complex structure, cumbersome jettisoning process, long jettisoning time, and the need for dynamic seals, which are inconvenient for installation and maintenance.

[0006] Secondly, this application proposes an underwater vehicle, including: a jettisoning device as described above.

[0007] The underwater vehicle provided in this application includes the jettisoning device of the above-mentioned technical solution, and therefore has all the beneficial effects of the jettisoning device, which will not be repeated here.

Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0013] The following reference Figures 1 to 5 This application describes a jettisoning device and an underwater vehicle provided according to some embodiments thereof.

[0014] like Figures 1 to 5 As shown, Figure 1 This is a schematic diagram of the structure of a load-discharging device 100 according to an embodiment of this application; Figure 2 for Figure 1 A schematic diagram of the MM cross-sectional structure of the launch device 100 in the embodiment shown.

[0015] According to the first aspect of this application, Figure 1 and Figure 2As shown, an embodiment of this application provides a jettisoning device 100 for an underwater vehicle 200. The jettisoning device 100 includes: a mounting cylinder 110 and an isolation cover 120, the mounting cylinder 110 and the isolation cover 120 being fixedly connected and forming a mounting cavity 130; a drive assembly 140 disposed within the mounting cavity 130, and a first magnetic pole piece 142 being provided on the outer peripheral surface of the drive assembly 140 located on one side of the isolation cover 120; and a driven assembly 160 sleeved on the isolation cover 120, the drive assembly 140 and the driven assembly 160 being rotatably connected, the driven assembly 160 having a first magnetic pole piece 142 opposite to the first magnetic pole piece 142 inside. Two magnetic pole pieces 162; a mounting assembly 170, one end of which is connected to the driven assembly 160, and the other end is provided with an annular groove structure 172, and a notch 174 is provided on one side of the annular groove structure 172; a throwing assembly 180, one end of which is provided with a ball head structure 182, which is engaged in the annular groove structure 172 through the notch 174 and can slide along the annular groove structure 172; wherein, the driving assembly 140 drives the driven assembly 160 to rotate through the magnetic coupling between the first magnetic pole piece 142 and the second magnetic pole piece 162, so that the ball head structure 182 can be disengaged from the notch 174 to achieve throwing.

[0016] Specifically, such as Figure 1 and Figure 2 As shown, the launch device 100 includes a mounting cylinder 110, an isolation cover 120, a drive assembly 140, a driven assembly 160, a mounting assembly 170, and a launch assembly 180. The mounting cylinder 110 is fixedly connected to the isolation cover 120, forming a mounting cavity 130 to facilitate the installation of the drive assembly 140. The drive assembly 140 is disposed within the mounting cavity 130, with one end of the drive assembly 140 located on one side of the mounting cylinder 110 and the other end located on one side of the isolation cover 120. A first magnetic pole piece 142 is provided on the outer peripheral surface of the drive assembly 140 located on the isolation cover 120 side. The purpose of providing the first magnetic pole piece 142 on the drive assembly 140 located on the isolation cover 120 side is to facilitate magnetic coupling between the magnetic pole pieces.

[0017] Specifically, the driven component 160 is sleeved on the isolation cover 120, and the drive component 140 and the driven component 160 are rotatably connected through a bearing. The driven component 160 is provided with a second magnetic pole piece 162 inside, and the second magnetic pole piece 162 is arranged opposite to the first magnetic pole piece 142 so that the first magnetic pole piece 142 and the second magnetic pole piece 162 can be magnetically coupled, thereby enabling the transmission of a larger torque.

[0018] Specifically, one end of the mounting component 170 is connected to the driven component 160, and the other end of the mounting component 170 is provided with an annular groove structure 172. A notch 174 is provided on one side of the annular groove structure 172. The notch 174 on the annular groove structure 172 facilitates the insertion and release of the load-release component 180 from the notch 174, thereby enabling the rapid mounting and release of the load-release component 180 and improving the release efficiency of the load-release device 100.

[0019] Specifically, one end of the ejection assembly 180 is provided with a ball-shaped structure 182, which is engaged within the annular groove structure 172 through a notch 174 and can slide within the annular groove structure 172. The drive assembly 140 drives the driven assembly 160 to rotate through the magnetic coupling between the first magnetic pole piece 142 and the second magnetic pole piece 162, so that the ball-shaped structure 182 can disengage from the notch 174 to achieve ejection. That is, when the underwater vehicle 200 needs counterweight, the jettison assembly 180 can be mounted on the mounting assembly 170 through the cooperation of the ball head structure 182 and the annular groove structure 172 to provide counterweight for the underwater vehicle 200. When the underwater vehicle 200 needs to reduce weight, the drive assembly 140 drives the first magnetic pole piece 142 to rotate, and drives the driven assembly 160 and the mounting assembly 170 to rotate through the magnetic coupling between the first magnetic pole piece 142 and the second magnetic pole piece 162, so that the ball head structure 182 in the jettison assembly 180 slides out from the notch 174 to achieve jettison, that is, to achieve weight reduction of the jettison device 100.

[0020] Specifically, the working principle of this application is as follows: After the underwater glider receives a control signal from the main control unit when a problem occurs, the control drive component 144, such as the output shaft 146 of the combined motor, rotates in a certain direction. The rotation of the output shaft 146 drives the first magnetic pole piece 142, i.e., the inner magnetic pole, to rotate synchronously. The first magnetic pole piece 142 drives the second magnetic pole piece 162, i.e., the outer magnetic pole, to rotate. In turn, the outer magnetic pole drives the driven component 160 and the mounting component 170 to rotate. The ball head structure 182 of the jettison component 180 slides to the notch 174 of the annular groove structure 172 and falls off under the action of gravity. The weight of the entire underwater glider is reduced, the buoyancy is greater than its own weight, and the underwater glider rises quickly.

[0021] The jettison device 100 provided in this application adopts a modular design. The entire jettison device 100 can be integrated as a separate system into the body 210 of an underwater vehicle 200, such as an underwater glider. The connection method is simple, facilitating later maintenance and replacement. Furthermore, the jettison device 100 uses magnetic coupling to transmit torque. By rationally arranging the positions of the first magnetic pole piece 142 and the second magnetic pole piece 162, the magnetic coupling between the magnetic pole pieces can transmit a larger torque, while avoiding dynamic seals. This avoids problems such as high power consumption and water leakage caused by easy wear of the sealing rings due to dynamic seals. In addition, while ensuring torque, the jettison device 100 transmits power through a direct connection between the drive component 140 and the driven component 160, eliminating the intermediate transmission mechanism. This results in high space utilization, light weight, and a compact structure, making it easy to install on the body 210 of an underwater vehicle 200, such as an underwater glider, and also facilitating maintenance. The jettison device 100 provided in this application solves the technical problems of existing underwater vehicles, such as complex jettison device structure, cumbersome jettison process, long jettison time, and the need for dynamic sealing, which makes it inconvenient to install and maintain.

[0022] Specifically, in related technologies, existing underwater vehicle jettisoning devices are not modular in design, relying on multi-stage transmission mechanisms, which results in large space occupation, difficult integration, and the need for waterproof sealing of transmission and jettisoning components, leading to high power consumption and easy wear and leakage of seals. Moreover, the unlocking process is cumbersome and has a long response time, affecting the maneuverability of the vehicle. Therefore, the jettisoning device has problems such as complex structure, cumbersome jettisoning process, long jettisoning time, and the need for dynamic sealing, which makes it inconvenient to install and maintain.

[0023] This application addresses this issue, such as Figure 1 and Figure 2 As shown, this application provides a modular, unsealed, and highly reliable magnetic coupling ejection device that achieves rapid ejection through rotational drive while reducing maintenance costs.

[0024] Specifically, the jettison device 100 adopts a modular design. The entire jettison device 100 can be integrated as a separate system into the underwater vehicle 200, such as the underwater glider body. The connection method is simple, which facilitates later maintenance and replacement, solving the problem of inconvenient installation and maintenance of existing jettison devices 100 due to their non-modular design. By setting a first magnetic pole piece 142 on the drive component 140 and a second magnetic pole piece 162 opposite to the first magnetic pole piece 142 inside the driven component 160, magnetic coupling torque transmission is achieved. This method not only transmits greater torque, but also avoids problems such as high power consumption caused by dynamic sealing and water leakage caused by easy wear of the sealing ring, thus improving the reliability and service life of the jettison device 100. In addition, by setting an annular groove structure 172 at one end of the mounting component 170, and a notch 174 on one side of the annular groove structure 172, and a ball head structure 182 at one end of the jettison component 180, the ball head structure 182 is engaged in the annular groove structure 172 through the notch 174 and can slide within the annular groove structure 172. This design enables the jettison assembly 180 to be quickly mounted and jettisoned, improving the jettison efficiency of the jettison device 100 and solving the problems of cumbersome jettisoning processes and long jettisoning times in existing jettisoning devices. Furthermore, the direct connection between the drive assembly 140 and the driven assembly 160 eliminates the need for an intermediate transmission mechanism, resulting in high space utilization, light weight, and a compact structure. This design facilitates the installation of the jettison device 100 on the fuselage 210 of an underwater vehicle 200, such as an underwater glider, and also simplifies maintenance.

[0025] The jettison device 100 of this application achieves a modular, lightweight, and compact design while ensuring torque, thereby improving jettison efficiency, reducing power consumption and maintenance costs, and solving the problems of complex structure, jettison delay, and reliance on dynamic seals in existing underwater vehicle jettison devices.

[0026] In specific applications, such as Figure 2 As shown, the mounting cylinder 110 can be specifically a combined motor mounting base, the isolation cover 120 can be specifically an isolation cover or an inner magnetic pole isolation cover, the first magnetic pole piece 142 can be specifically an inner magnetic pole, and the second magnetic pole piece 162 can be specifically an outer magnetic pole. The mounting cylinder 110 and the isolation cover 120 are connected and fixed together by screws or bolts. Two O-rings are provided between the mounting cylinder 110 and the isolation cover 120 for sealing. Specifically, the two O-rings can be set as a third sealing ring 330 and a fourth sealing ring 340, namely O-ring V and O-ring D. Two O-rings are also provided between the machine body 210 and the mounting cylinder 110 for sealing. The two O-rings can be specifically set as a fifth sealing ring 350, namely O-ring E. The specific selection can be made according to the actual use situation, and will not be listed here.

[0027] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, the drive assembly 140 includes: a drive member 144, one end of which is provided with an output shaft 146; a fixed base 148, which includes an insertion hole 150 in which the output shaft 146 is inserted; and a fixing pin 152, which is inserted into the fixed base 148 along an axial direction perpendicular to the output shaft 146 to connect and fix the drive member 144 and the fixed base 148.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, the drive assembly 140 includes a drive member 144, a fixed base 148, and a fixing pin 152. One end of the drive member 144 is provided with an output shaft 146, and the fixed base 148 is provided with an insertion hole 150. The output shaft 146 can be directly inserted into the insertion hole 150. This direct connection between the output shaft 146 of the drive member 144 and the fixed base 148 eliminates the intermediate transmission mechanism, resulting in a compact structure, saving space, simplifying traditional multi-stage transmission, and improving space utilization. The fixing pin 152 is inserted into the fixed base 148 in an axial direction perpendicular to the output shaft 146, thereby connecting and fixing the drive member 144 and the fixed base 148, preventing rotation between the output shaft 146 and the fixed base 148, and improving connection reliability.

[0029] Specifically, by directly inserting the output shaft 146 of the drive component 144 into the insertion hole 150 of the fixed base 148, a direct connection between the drive component 144 and the fixed base 148 is achieved, eliminating the intermediate transmission mechanism. This makes the entire drive assembly 140 more compact, saves installation space, and improves space utilization. The fixing pin 152, inserted into the fixed base 148 along an axial direction perpendicular to the output shaft 146, effectively connects and fixes the drive component 144 and the fixed base 148, preventing relative rotation between the output shaft 146 and the fixed base 148, and improving the reliability and stability of the connection.

[0030] In specific applications, such as Figure 2 and Figure 4 As shown, the driving component 144 can be specifically a load-bearing combined motor, the fixing seat 148 can be specifically an inner magnetic pole fixing seat, the fixing pin 152 can be specifically a cylindrical pin, the insertion hole 150 on the fixing seat 148 can be specifically a countersunk hole, and the inner magnetic pole fixing seat is provided with a first boss 360. The boss structure can ensure that the first magnetic pole piece 142, that is, the inner magnetic pole piece, will not rotate. The specific choice can be made according to the actual use situation, and will not be listed here.

[0031] In some embodiments, optionally, such as Figure 1 and Figure 2As shown, the drive assembly 140 further includes: a plurality of first magnetic pole pieces 142, which are evenly distributed on the outer peripheral surface of the fixing base 148; and a clamping member 154, which is disposed on one end of the fixing base 148 and is used to fix the plurality of first magnetic pole pieces 142.

[0032] Specifically, such as Figure 2 and Figure 3 As shown, the drive assembly 140 also includes first magnetic pole pieces 142 and clamping members 154. Multiple first magnetic pole pieces 142 are evenly distributed on the outer peripheral surface of the fixed base 148. By rationally arranging the positions of the first magnetic pole pieces 142, a larger torque can be transmitted, improving the power of the throwing device 100. The clamping member 154 covers one end of the fixed base 148 and is used to fix the multiple first magnetic pole pieces 142, preventing the first magnetic pole pieces 142 from shifting and affecting the magnetic coupling effect.

[0033] Specifically, by arranging multiple first magnetic pole pieces 142 evenly distributed on the outer periphery of the fixed base 148, this layout ensures a more uniform magnetic field distribution among the pole pieces, thereby optimizing the magnetic coupling effect. This allows the drive assembly 140 to transmit greater torque, improving the power performance of the throwing device 100. A clamping member 154 is placed over one end of the fixed base 148, effectively fixing the multiple first magnetic pole pieces 142 and preventing positional movement during operation. This design not only enhances the structural stability of the drive assembly 140 but also ensures the continuity and reliability of the magnetic coupling effect, avoiding performance degradation or malfunctions caused by pole piece movement. Furthermore, the design of the first magnetic pole pieces 142 and the clamping member 154 also considers ease of installation and maintenance. Multiple first magnetic pole pieces 142 can be pre-installed on the fixed base 148 and then fixed by the clamping member 154. This installation method is simple and quick, improving production efficiency. Simultaneously, when maintenance or replacement of the pole pieces is required, the clamping member 154 can be easily disassembled for operation.

[0034] In specific applications, the first magnetic pole piece 142 can be specifically an inner magnetic pole, and the clamping member 154 can be specifically an inner magnetic pole clamping member. The clamping member 154 can be fixed on the fixing base 148 by screws or bolts to clamp the first magnetic pole piece 142. The specific selection can be made according to the actual use situation, and will not be listed here.

[0035] In some embodiments, optionally, such as Figure 2As shown, the ejection device 100 further includes: a first bearing member 190, disposed at one end of the isolation cover 120; a second bearing member 192, disposed at the other end of the isolation cover 120; the driven component 160 is rotatably connected to the drive component 140 through the first bearing member 190 and the second bearing member 192; and a pressure cover 194, which is disposed at one end of the isolation cover 120 for pressing and fixing the first bearing member 190.

[0036] Specifically, such as Figure 2 As shown, the loading device 100 also includes a first bearing 190, a second bearing 192, and a pressure cap 194. The first bearing 190 is disposed at one end of the isolation cover 120, specifically on the side of the isolation cover 120 away from the drive assembly 140; the second bearing 192 is disposed at the other end of the isolation cover 120, specifically on the side of the isolation cover 120 closer to the drive assembly 140. By providing the first bearing 190 and the second bearing 192, the driven assembly 160 can be rotatably connected to the drive assembly 140 via the first bearing 190 and the second bearing 192. That is, the driven assembly 160 can rotate relative to the drive assembly 140 via the first bearing 190 and the second bearing 192, thereby driving the mounting assembly 170 to rotate. The pressure cap 194 is fixed to one end of the isolation cover 120, specifically the side of the isolation cover 120 away from the drive assembly 140, for pressing and fixing the first bearing 190, so as to achieve stable installation of the first bearing 190 and the second bearing 192, thereby achieving a stable connection between the drive assembly 140 and the driven assembly 160.

[0037] Specifically, such as Figure 2 As shown, by providing a first bearing 190 and a second bearing 192 at both ends of the isolation enclosure 120, the driven assembly 160 can be stably rotatably connected to the drive assembly 140. This design not only ensures the smooth rotation of the driven assembly 160 but also greatly improves the stability of rotation, reducing performance loss or failure risks caused by poor rotation or shaking. Furthermore, the pressure cap 194 further optimizes the positioning and fixation of the first bearing 190. By pressing and fixing the first bearing 190 with the pressure cap 194, not only is the stable installation of the first bearing 190 on the isolation enclosure 120 ensured, but the stability of the second bearing 192 and the entire rotatable connection structure is also indirectly enhanced. This design improves the overall structural strength and reliability of the ejection device 100.

[0038] In specific applications, the first bearing component 190 can be a ceramic bearing F, the second bearing component 192 can be a ceramic bearing K, and the cover 194 can be a ceramic bearing cover. It can be fixed to the isolation cover 120 by screws or bolts to press the inner ring of the ceramic bearing and fix the first bearing component 190 and the second bearing component 192. The specific selection can be made according to the actual use situation, and will not be listed here.

[0039] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, the driven assembly 160 includes: an inner housing 164, which is sleeved on the isolation cover 120 and disposed on the first bearing member 190 and the second bearing member 192; an outer housing 166, which is sleeved on the inner housing 164, and the inner housing 164 and the outer housing 166 enclose a receiving cavity 168; and a plurality of second magnetic pole pieces 162, which are disposed in the receiving cavity 168 and evenly distributed on the outer peripheral surface of the inner housing 164; wherein each first magnetic pole piece 142 is correspondingly disposed to each second magnetic pole piece 162.

[0040] Specifically, such as Figure 2 As shown, the driven assembly 160 includes an inner housing 164, an outer housing 166, and a plurality of second magnetic pole pieces 162. The inner housing 164 is fitted onto the isolation cover 120 and is disposed on the first bearing member 190 and the second bearing member 192. The outer housing 166 is fitted onto the inner housing 164, and a receiving cavity 168 is formed between the inner housing 164 and the outer housing 166 for housing the second magnetic pole pieces 162. There are multiple second magnetic pole pieces 162, which are disposed within the receiving cavity 168 and evenly distributed on the outer peripheral surface of the inner housing 164. Each first magnetic pole piece 142 corresponds to each second magnetic pole piece 162, with one first magnetic pole piece 142 corresponding to one second magnetic pole piece 162. This allows for the transmission of greater torque and improves the power of the throwing device 100.

[0041] Specifically, by evenly distributing multiple second magnetic pole pieces 162 on the outer periphery of the inner shell 164 and corresponding one-to-one with the first magnetic pole pieces 142 on the drive assembly 140, this layout greatly optimizes the magnetic coupling transmission effect. The magnetic field interaction between each first magnetic pole piece 142 and its corresponding second magnetic pole piece 162 is more direct and efficient, thereby transmitting greater torque and improving the dynamic performance of the jettisoning device 100. In addition, the driven assembly 160 adopts a design in which the inner shell 164 and the outer shell 166 are fitted together, forming a cavity 168 to house the second magnetic pole pieces 162. This structure is compact and has high space utilization. It not only saves installation space but also makes the entire jettisoning device 100 lighter and easier to integrate into the underwater vehicle 200. The fitted design of the inner shell 164 and the outer shell 166, as well as the evenly distributed layout of the second magnetic pole pieces 162, enhances the overall structural stability of the driven assembly 160. This design reduces the risk of magnetic pole piece displacement or damage due to vibration or impact, improving the reliability and service life of the ejection device 100. The modular design of the driven assembly 160 simplifies and expedites installation and maintenance. When the second magnetic pole piece 162 needs to be replaced or repaired, the outer casing 166 can be easily disassembled for operation, reducing maintenance difficulty and cost. Compared to the problems of low magnetic coupling transmission efficiency, complex structure, and difficult installation and maintenance that may exist in the prior art, the driven assembly 160 design of this application effectively solves these problems by optimizing the magnetic pole piece layout, adopting a compact nested structure, and using a modular design. This improvement not only enhances the performance and reliability of the ejection device 100 but also reduces installation and maintenance costs.

[0042] In specific applications, such as Figure 2 and Figure 5 As shown, the inner shell 164 can specifically be an outer magnetic pole isolation cover, the outer shell 166 can specifically be an outer magnetic pole shell, and the second magnetic pole piece 162 can specifically be an outer magnetic pole or an outer magnetic pole piece. The second magnetic pole pieces 162 are evenly arranged on the inner shell 164. The inner shell 164 is provided with a second boss 370. The boss structure can prevent the second magnetic pole piece 162, i.e., the outer magnetic pole piece, from rotating on the circumference. The outer shell 166 is fixed to the inner shell 164 by screws or bolts and sealed by two O-ring seals. The two O-ring seals can specifically be a first seal 310 and a second seal 320, i.e., O-ring seal A and O-ring seal B, to improve the sealing performance of the receiving cavity 168 between the inner shell 164 and the outer shell 166 and prevent the second magnetic pole piece 162 from contacting water. Other options can be selected according to the actual use and will not be listed here.

[0043] In some embodiments, optionally, such as Figure 1 and Figure 2As shown, the mounting assembly 170 includes: a drive wheel 176, one end of which has a threaded hole, and the drive wheel 176 is connected to the driven assembly 160 through the threaded hole; the other end of the drive wheel 176 is provided with a connecting shaft 188; and a driven wheel 178, which is disposed on the connecting shaft 188. The drive wheel 176 and the driven wheel 178 form an annular groove structure 172.

[0044] Specifically, such as Figure 2 As shown, the mounting assembly 170 includes a driving wheel 176 and a driven wheel 178. One end of the driving wheel 176 has a threaded hole, and the outer casing 166 has an extension shaft near the end of the mounting assembly 170. The extension shaft has external threads, and the driving wheel 176 connects to the external threads of the extension shaft of the outer casing 166 through the threaded hole. The other end of the driving wheel 176 has a connecting shaft 188, and the driven wheel 178 is sleeved on the connecting shaft 188. The driving wheel 176 and the driven wheel 178 form an annular groove structure 172, which can mount the launch assembly 180.

[0045] Specifically, the annular groove structure 172 formed between the driving wheel 176 and the driven wheel 178 provides a mounting point for the load-release assembly 180. The load-release assembly 180 is engaged in the notch 174 of the annular groove structure 172 via the ball head structure 182, achieving rapid loading. When load release is required, the drive assembly 140 drives the driven assembly 160 to rotate, which in turn drives the driving wheel 176 and the driven wheel 178 to rotate, causing the ball head structure 182 of the load-release assembly 180 to slide out of the notch 174, achieving rapid load release. This design simplifies the load-release process and improves load-release efficiency. The driving wheel 176 is connected to the driven assembly 160 via a threaded hole. This connection method is simple and reliable, ensuring stable transmission between the driving wheel 176 and the driven assembly 160. Simultaneously, the driven wheel 178 is sleeved on the connecting shaft 188 of the driving wheel 176, forming the annular groove structure 172. This design also increases the overall structural strength of the load-release assembly 170. Compared with the problems of complex mounting structure and cumbersome unloading process that may exist in the prior art, the mounting component 170 of this application is designed to achieve rapid mounting and unloading through a simple structure of driving wheel 176 and driven wheel 178, while ensuring the reliability of connection and the stability of structure, improving the performance and efficiency of unloading device 100, and reducing maintenance costs.

[0046] In practical applications, the drive wheel 176 is threadedly connected to the housing 166 and secured with screws or bolts to prevent rotation. The driven wheel 178 is fixed to the drive wheel 176 with a nut. Other options can be selected based on actual usage and are not listed here.

[0047] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, a notch 174 is provided on the driven wheel 178, and the notch 174 is located on the annular groove structure 172.

[0048] Specifically, such as Figure 2 As shown, a notch 174 is provided on the side wall of the driven wheel 178. When the driving wheel 176 and the driven wheel 178 enclose and form an annular groove structure 172, a notch 174 will be formed on the annular groove structure 172, which facilitates the mounting and throwing of the load-bearing assembly 180 and improves the load-bearing efficiency.

[0049] Specifically, the notch 174 on the side wall of the driven wheel 178 provides a convenient channel for the mounting and dismounting of the ejection assembly 180. During mounting, the ball head structure 182 of the ejection assembly 180 can easily engage with the annular groove structure 172 through the notch 174, achieving rapid mounting. During ejection, as the driving wheel 176 and the driven wheel 178 rotate, the ball head structure 182 of the ejection assembly 180 can smoothly slide out through the notch 174, achieving rapid dismounting. This design effectively simplifies the ejection process and improves ejection efficiency. Because the notch 174 on the side wall of the driven wheel 178 makes the mounting and ejection process of the ejection assembly 180 simpler and faster, it also reduces the maintenance difficulty and cost of the ejection device 100. When it is necessary to replace or repair the ejection assembly 180, it can be easily operated through the notch 174 without the need for large-scale disassembly or adjustment of the ejection device 100. Compared with the problems of cumbersome loading and unloading processes and low efficiency that may exist in the prior art, this application realizes the rapid loading and unloading of the unloading assembly 180 by designing a notch 174 on the side wall of the driven wheel 178, which significantly improves the unloading efficiency.

[0050] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, the throwing assembly 180 includes: a throwing support 184, one end of which is provided with a ball head structure 182, which is movably connected to the annular groove structure 172 and slides within the annular groove structure 172 as the annular groove structure 172 rotates; and a throwing lead block 186, which is provided at the other end of the throwing support 184 and is used to provide counterweight for the throwing device 100.

[0051] Specifically, such as Figure 2 As shown, the launching assembly 180 includes a launching support 184 and a launching lead block 186. One end of the launching support 184 is provided with a ball-head structure 182, which is movably connected within an annular groove structure 172 and slides within the annular groove structure 172 as it rotates. The launching lead block 186 is disposed at the other end of the launching support 184 and serves as a counterweight for the launching device 100.

[0052] Specifically, the ball-head structure 182 at one end of the throwing support 184 is movably connected within the annular groove structure 172 and slides within the annular groove structure 172 as it rotates. This design allows the throwing support 184 to smoothly detach from the mounting assembly 170 during the throwing process, avoiding impacts and vibrations caused by sudden detachment, thus ensuring the stability of the throwing process. The throwing lead block 186 is located at the other end of the throwing support 184 and is used to provide counterweight for the throwing device 100. It can be understood that the throwing lead block 186 is specifically a counterweight. By rationally setting the weight and position of the throwing lead block 186, the center of gravity and stability of the throwing device 100 can be precisely adjusted. Compared to the potential problems of unstable throwing process, inaccurate counterweight, or complex installation and maintenance in existing technologies, the throwing assembly 180 design of this application effectively solves these problems through the movable connection between the ball-head structure 182 and the annular groove structure 172, and the precise counterweight of the throwing lead block 186. It can effectively improve the performance and stability of the ballast jettisoning device 100, and also reduce installation and maintenance costs.

[0053] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, the throwing device 100 also includes an elastic sheet 196. One end of the elastic sheet 196 is disposed on the mounting cylinder 110, and the other end of the elastic sheet 196 is provided with a through hole 198. The ball head structure 182 passes through the through hole 198 and is movably connected to the annular groove structure 172.

[0054] Specifically, the throwing device 100 also includes an elastic plate 196. One end of the elastic plate 196 is fixed to the mounting cylinder 110 by screws or bolts, and the other end of the elastic plate 196 has a through hole 198 through which the ball head structure 182 passes and is movably connected to the annular groove structure 172. By providing the elastic plate 196 between the mounting assembly 170 and the throwing assembly 180, the throwing assembly 180 can be prevented from shaking or vibrating during movement, reducing the impact force on the ball head structure 182, thus acting as a buffer to prevent damage to the ball head structure 182 and the annular groove structure 172 due to excessive impact force.

[0055] Specifically, one end of the elastic plate 196 is fixed to the mounting cylinder 110, and the other end is movably connected to the ball head structure 182 of the throwing support 184 through the through hole 198. This design allows the throwing assembly 180 to maintain a relatively stable position under load, reducing swaying or vibration caused by external factors (such as water flow impact, equipment vibration, etc.), thereby enhancing the overall structural stability of the throwing device 100. Because the elastic plate 196 itself is elastic, it can absorb and disperse some of the impact force during the movement of the throwing assembly 180. When the throwing assembly 180 undergoes a small displacement due to external factors, the elastic plate 196 can undergo elastic deformation, playing a buffering and shock-absorbing role, effectively reducing the impact force on the ball head structure 182, and preventing damage to the ball head structure 182 and the annular groove structure 172 due to excessive impact force. Compared to a throwing device 100 without the elastic plate 196, this application further optimizes the structural design and performance of the throwing device 100 by introducing the elastic plate 196. This improvement not only enhances the stability and reliability of the ejection device 100, but also extends its service life and ejection accuracy.

[0056] In specific applications, the elastic sheet 196 can be specifically set as a spring sheet or an elastic element, which can be selected according to the actual use situation, and will not be listed here.

[0058] The underwater vehicle 200 provided in this application includes the jettison device 100 of the above embodiments, and therefore has all the beneficial effects of the jettison device 100, which will not be repeated here. In specific applications, the underwater vehicle 200 may be an underwater glider or other underwater navigation equipment, and the jettison device 100 may be a magnetic coupling jettison device for an underwater glider.
