[0050] In the related art, the throwing device of the underwater vehicle includes a throwing tube, the throwing tube is controllable and the two ends of the throwing tube are connected to the inside and outside of the underwater vehicle, and domestic garbage and waste can be put into the throwing tube and thrown out under appropriate circumstances. The throwing tube is controllable through a valve or a cover, but usually the throwing tube will only be provided with one or two seals, and each seal is sealed by a sealing ring, and the sealing performance is not strong enough. When the underwater vehicle is sailing in a deep or high water pressure water area, this parabolic device is prone to leakage, etc., and there is a technical problem that it is difficult to apply to waters with a large depth or high water pressure. The embodiment of the present application provides an underwater parabolic device and an underwater parabolic method, which can at least solve the above technical problems to a certain extent.

[0051] The present application will be described below with reference to the accompanying drawings:

[0052] Figure 1 FIG. 1 shows a schematic diagram of the structure of an underwater parabolic device in some embodiments or certain embodiments of the present application, with reference to FIG. Figure 1 , the embodiment of the present application provides an underwater parabolic device, comprising:

[0053] The mounting base 1 is provided with a through hole 101 .

[0054] The two shells are both fixed to the mounting base 1 and are respectively located at two ends of the through hole 101 . The shells are provided with a channel 2 with one end communicating with the through hole 101 .

[0055] Two covers and a driving mechanism, the two covers are rotatably connected to the two shells respectively, and the covers are arranged at the other end of the channel 2 of the corresponding shell, and the driving mechanism is connected to the covers and is used to press the covers tightly against the shell.

[0056] The parabolic ball 4 and the transmission mechanism 6 are rotatably arranged in the channel 2 and dynamically sealed in the shell. The parabolic ball 4 is provided with a parabolic trough 401 opposite to the through hole 101. The transmission mechanism 6 is provided with a rotatable transmission shaft 601 that passes through the shell and is connected to the parabolic ball 4 at one end. There is an angle between the rotation center line of the transmission shaft 601 and the axis of the channel 2 where the parabolic ball 4 is located.

[0057] The mounting seat 1 in the underwater parabolic device can be installed in a desired underwater vehicle. The mounting seat 1 provides an installation space for other components in the underwater parabolic device, and the through hole 101 on the mounting seat 1 can connect the inside and the outside of the underwater vehicle. Two shells are fixed at both ends of the through hole 101 of the mounting seat 1, each shell has a channel 2 connected to the through hole 101 at one end, and each shell is rotatably connected with a cover arranged at the other end of the channel 2. The driving mechanism is connected to the cover and is used to make the cover press the shell. The shell and the cover can extend the space corresponding to the through hole 101, which is also convenient for the arrangement of components such as the cover. Among the two shells, one shell can be located inside the underwater vehicle, and the cover corresponding to the other shell can be connected to the outside of the underwater vehicle when opened, and the force applied by the driving mechanism to the cover is usually reversible. When it is not necessary to parabola, the driving mechanism can be controlled to make the cover press the corresponding shell to improve the sealing performance. When it is necessary to throw an object, the driving mechanism can be withdrawn from the force applied to the cover so that the cover can be opened. The overall sealing performance of the underwater parabolic device is good. A parabolic ball 4 is rotatably and dynamically sealed in the corresponding channel 2 in the channel 2 of the shell. The parabolic ball 4 is provided with a parabolic trough 401 opposite to the through hole 101, so that the garbage and waste to be thrown out can enter the parabolic trough 401 of the parabolic ball 4 from the through hole 101 of the mounting seat 1. The rotatable transmission shaft 601 of the transmission mechanism 6 in the underwater parabolic device passes through the shell and one end is connected to the parabolic ball 4, and there is an angle between the rotation center line of the transmission shaft 601 and the axis of the channel 2 where the parabolic ball 4 is located. When the transmission shaft 601 rotates, the parabolic ball 4 can be driven to rotate. When the transmission shaft 601 rotates around the rotation center axis by a certain angle, the parabolic trough 401 of the parabolic ball 4 can be rotated to the position away from the through hole 101 of the mounting seat 1, so that the parabolic trough 401 can face the cover of the shell. Opening the cover of the shell can enable the garbage or waste to be thrown out. In addition to the two covers, the seal between the parabolic ball 4 and the channel 2 of the shell can also improve the overall sealing of the underwater parabolic device, so that the underwater parabolic device can maintain sealing under higher pressure, can be suitable for underwater vehicles sailing in higher pressure environments, can improve the applicability of underwater vehicles to waters with greater depth and pressure, and to a certain extent solve the technical problem that the parabolic device is difficult to apply to waters with greater depth or greater water pressure.

[0058] It should be noted that underwater vehicles that need to carry people are usually provided with a throwing hole, and the mounting seat 1 can be installed at a position connected to the throwing hole of the underwater vehicle, or the mounting seat 1 can also be a mounting seat 1 of some devices in the underwater vehicle. The two shells and the cover in the underwater parabolic device can be respectively arranged inside or outside the underwater vehicle according to needs, and the parabolic ball 4 can be arranged in the channel 2 located outside the underwater vehicle. When the cover located outside the underwater vehicle is opened, the pressure liquid enters the shell and also presses the parabolic ball 4 toward the mounting seat 1, which is conducive to tightening the sealing between the parabolic ball 4 and the shell.

[0059] In some or certain embodiments, the mounting base 1 may be plate-shaped, and the through hole 101 of the mounting base 1 penetrates the mounting base 1 along the thickness direction thereof, so as to facilitate preparation and installation.

[0060] In some or certain embodiments, the mounting seat 1 can also be adjusted to a block-like shape or a bearing seat-like shape according to space requirements, etc.

[0061] Figure 2 FIG. 1 shows a schematic diagram of a parabolic ball structure in some embodiments or certain embodiments of the present application, with reference to FIG. Figure 1 and Figure 2 In some or some embodiments, the underwater parabolic device further comprises:

[0062] At least two annular seals 3 are respectively provided to seal between the parabolic ball 4 and the mounting seat 1 , and between the parabolic ball 4 and the inner wall of the shell of the passage 2 in which the parabolic ball 4 is located.

[0063] At least two annular seals 3 are respectively provided between the parabolic ball 4 and the mounting seat 1, and between the parabolic ball 4 and the inner wall of the shell of the passage 2, which can improve the sealing performance between the parabolic ball 4 and the shell, and between the parabolic ball 4 and the mounting seat 1. In addition to the two sealing covers, annular seals 3 are provided between the parabolic ball 4 and the shell, and between the parabolic ball 4 and the mounting seat 1, so that the underwater parabolic device can have multiple seals when in use, effectively improving the sealing performance of the underwater parabolic device, so as to increase the upper limit of the pressure that the underwater parabolic device can adapt to. In addition, since the parabolic ball 4 itself is in an arc shape, at least two annular seals 3 are respectively provided between the parabolic ball 4 and the shell, and between the parabolic ball 4 and the mounting seat 1, which also facilitates the installation of the parabolic ball 4 and improves the sealing effect.

[0064] It should be noted that the parabolic ball 4 rotates relative to the annular seal 3 to form a dynamic seal.

[0065] In some or certain embodiments, the mounting seat 1 is further provided with a mounting groove 102 surrounding one end of the through hole 101, the mounting groove 102 is opposite to the parabolic ball 4, the mounting groove 102 may be columnar and the annular seal 3 is coaxially arranged in the mounting groove 102, and the diameter of the parabolic ball 4 is larger than the aperture of the through hole 101 of the mounting seat 1. When the parabolic ball 4 is subjected to external pressure, the annular seal 3 can be pressed tightly in the mounting groove 102, which is conducive to improving the overall sealing of the underwater parabolic device, and the increase of the mounting groove 102 in this section is also conducive to reducing the installation space required for the parabolic ball 4, which is convenient for overall installation and preparation.

[0066] In some or certain embodiments, an annular protrusion surrounding the through hole 101 may also be provided on the mounting seat 1, and the parabolic ball 4 may also be sealed with the annular protrusion of the mounting seat 1 and the inner wall of the housing. Alternatively, an annular protrusion may be provided on the inner peripheral wall of the housing, and the parabolic ball 4 may be clamped in the housing in accordance with the shape of the housing and the annular protrusion, so as to realize the rotation and sealing of the parabolic ball 4. Alternatively, an annular conical surface surrounding one end of the through hole 101 may also be provided on the mounting seat 1, and the annular conical surface may be fitted with the surface of the parabolic ball to realize the rotation and dynamic sealing of the parabolic ball 4.

[0067] In some or certain embodiments, the annular seal 3 disposed between the parabolic ball 4 and the mounting seat 1 is a hard seal with the parabolic ball 4 and a soft seal with the mounting seat 1. This can achieve effective support for the parabolic ball 4 and improve the sealing effect.

[0068] In some or certain embodiments, the annular seal 3 may include a plate-shaped annular body 301 and a first sealing ring 302 coaxially embedded in the outer peripheral wall of the annular body 301. The inner peripheral wall of the annular body 301 is provided with annular fitting surfaces 3011 for fitting and sealing with the surface of the parabolic ball 4 at both ends. The annular body 301 may be made of a hard metal material. The annular seal 3 adopts such a structure, which can effectively support the parabolic ball 4. At the same time, the annular fitting surface 3011 of the annular body 301 is used to achieve a hard seal with the parabolic ball 4. The first sealing ring 302 achieves a soft seal, and the rotation resistance of the parabolic ball 4 is also small, which is conducive to the throwing of the object to be thrown, and can effectively improve the sealing performance of the underwater parabolic device.

[0069] In some or certain embodiments, the parabolic ball 4 is further provided with a driving slot 402 spaced apart from the parabolic slot 401, one end of the transmission shaft 601 of the driving mechanism can be inserted into the driving slot 402 and connected to the parabolic ball 4, and one end of the transmission shaft 601 and the parabolic ball 4 can be connected by a structure such as a spline, etc., so as to facilitate the overall assembly of the underwater parabolic device and also realize the rotation of the parabolic ball 4.

[0070] In some or certain embodiments, the two shells respectively located at the two ends of the through hole 101 of the mounting seat 1 can be set to the same structure, and the structures of the two covers can also be the same. It can also achieve the coordination with the parabolic ball 4 and the normal throwing of the thrown objects. For components or equipment that need to be exposed to water, corresponding pressure-resistant and waterproof components or equipment can be used.

[0071] In some or certain embodiments, based on the requirements of space, installation or service life, the two shells, covers and driving mechanisms may also be set to different structures. For ease of understanding, the shell containing the parabolic ball 4 is divided into an outer shell 5, and the other shell is an inner shell 11. The covers and driving mechanisms corresponding to the outer shell 5 are respectively an outer cover 7 and an outer driving mechanism 8, and the covers and driving mechanisms corresponding to the inner shell 11 are respectively an inner cover 9 and an inner driving mechanism 10. The underwater parabolic device is described below on this basis.

[0072] Figure 3 FIG. 1 shows a schematic diagram of the structure of an outer shell in some embodiments or certain embodiments of the present application, with reference to FIG. Figure 3 The outer shell 5 may be a cylinder with a variable aperture. The outer shell 5 may include a connecting section 501, a transition section 502 and a matching section 503 which are coaxially connected in sequence. The connecting section 501 is a straight cylinder with an aperture smaller than the matching section 503. The inner peripheral wall of the connecting section 501 at one end away from the matching section 503 has a coaxial annular support 504. The annular seal 3 may be coaxially supported on the annular support 504 and seal-match with the inner peripheral wall of the connecting section 501. The aperture of the transition section 502 gradually increases in the direction from the connecting section 501 to the matching section 503, and may match with the surface of the parabolic ball 4, which is conducive to the installation of the parabolic ball 4 and reduces the gap between the outer shell 5 and the parabolic ball 4. The outer peripheral wall of the matching section 503 at one end away from the connecting section 501 may have an annular connecting plate 505. The annular connecting plate 505 may surround one end of the through hole 101 and be detachably connected to the mounting seat 1 through bolts, nuts and other components.

[0073] In some or certain embodiments, the end of the annular connecting plate 505 away from the connecting section 501 is further provided with a coaxial annular protrusion 506, the mounting groove 102 may be provided with an annular stopper 103 surrounding the through hole 101 and cooperating with the annular protrusion 506, and a second sealing ring is provided between the annular protrusion 506 and the annular stopper 103. This facilitates the positioning and installation between the outer shell 5 and the mounting seat 1, and helps to improve the sealing performance.

[0074] In some or certain embodiments, the outer peripheral wall of the outer shell 5 may be provided with a protruding bracket 507, and the bracket 507 may be used to connect with the external driving mechanism 8. The outer shell 5 and the parabolic ball 4 may be made of metal or alloy material, which has high strength and hardness, and is conducive to improving pressure resistance.

Both ends of the transmission rod 604 are provided with coaxial transmission bevel gears 605. The two transmission bevel gears 605 are respectively meshed with the bevel gear end 6021 and the driving bevel gear 603.

[0078] The transmission mechanism 6 for driving the parabolic ball 4 adopts the above arrangement, which can reduce the space required for the overall installation and facilitate the driven rotation of the parabolic ball 4. Both ends of the transmission rod 604 adopt transmission bevel gears 605 for meshing transmission, and the mechanical transmission is also convenient for working in water. When the cover corresponding to the shell where the parabolic ball 4 is located is opened, it can be connected to the outside of the underwater vehicle, and the first driving mechanism can be located inside the underwater vehicle.

[0079] In some or certain embodiments, the first driving element 602 may be an electric motor or a motor having a bevel gear fixed at the end of the output shaft, and the base of the electric motor or the motor may be fixedly connected to the inner housing 11, and the bevel gear fixed to the output shaft of the electric motor or the motor is configured as a bevel gear end 6021.

[0082] In some or certain embodiments, the outer cover 7 may include an outer cover body 702, a sealing ring 703, a pressure ring 704 and an annular protrusion 506 plate. The outer cover body 702 may be disc-shaped, and one end is provided with a connection point 7021 connected to the external driving mechanism 8, and the other end is provided with an outer cover circular groove 7022. The sealing ring 703 is coaxially arranged in the outer cover circular groove 7022, the pressure ring 704 is coaxially pressed on the sealing ring 703, the annular protrusion 506 plate is coaxially pressed on the pressure ring 704, and the sealing ring 703, the pressure ring 704 and the annular protrusion 506 plate are connected by fasteners such as screws or bolts, and the corresponding screws or bolts are inserted into the outer cover body 702 to form an integrated structure of the outer cover 7. The annular protrusion 506 plate includes a barrel-shaped protrusion, and an annular portion 705 surrounding an open end of the barrel-shaped protrusion and integrally formed with the barrel-shaped protrusion, the annular portion 705 is connected with a fastener such as a screw or a bolt, and the barrel-shaped protrusion protrudes relative to the annular portion 705 to form an anti-collision portion 701. There may be a certain buffer space between the barrel-shaped protrusion and the outer cover body 702.

[0083] The sealing ring 703 can achieve sealing between the outer cover body 702 and the outer shell 5. The above structure is also easy to install, and the barrel-shaped protrusion can also play a buffering role, reducing the possibility that the outer cover 7 will be damaged by garbage or waste waiting to be thrown out, thereby increasing the service life of the outer cover 7. The connection point 7021 can be an ear plate, which is convenient for connection with structures such as a hinge shaft.

[0084] In some or certain embodiments, the anti-collision portion 701 of the outer cover 7 may also be a structure fixedly connected to the outer cover body 702 and having a certain elasticity, which is not limited in the present application. The sealing ring 703 may be a self-tightening lip sealing ring with a better sealing effect.

[0085] Figure 5 FIG. 1 shows a schematic diagram of the structure of an external drive mechanism in some embodiments or certain embodiments of the present application, with reference to FIG. Figure 5 In some or certain embodiments, the driving mechanism corresponding to the outer cover 7 is divided into an outer driving mechanism 8, and the outer driving mechanism 8 includes:

[0086] The outer driving element 801 is provided with a moving rod 8011 which has one end passing through the mounting seat 1 and forms a dynamic seal with the mounting seat 1 and moves back and forth along its own axial direction.

[0087] One end of the pull rod 802 is hinged to one end of the moving rod 8011.

[0088] The lever 803 is provided with a first hinge point 8031, a second hinge point 8032 and a third hinge point 8033 which are arranged in parallel and spaced apart from each other. The first hinge point 8031 ​​is hinged to the other end of the pull rod 802, the second hinge point 8032 is hinged to the outer shell 5, the third hinge point 8033 is hinged to the outer cover 7, and the rotation planes of the lever 803 and the pull rod 802 are the same plane.

[0089] The above arrangement of the outer driving mechanism 8 is also conducive to improving the service life of the outer driving mechanism 8. When the outer driving element 801 drives the moving rod 8011 to move along its own axial direction, the pull rod 802 can be pulled to move. The movement of the pull rod 802 is transmitted to the first hinge point 8031 ​​of the lever 803, so that the lever 803 can rotate around the second hinge point 8032 hinged to the outer shell 5. The rotation of the lever 803 will drive the outer cover 7 hinged to the third hinge point 8033 of the lever 803 to move to open the channel 2 corresponding to the outer shell 5. The flexibility is high and the stability of use is good.

[0090] In the present application, the first, second and third hinge points can all be hinge holes provided on the lever 803, and these hinge holes are respectively connected to the pull rod 802, the outer shell 5 and the cover through corresponding hinge axes.

[0091] In some or certain embodiments, the external driving element 801 may be an electric motor or a stepper motor or a motor with a manual control component, etc.

[0092] In some or certain embodiments, the mounting base 1 may be provided with a through hole 104 that matches the moving rod 8011, and the external driving mechanism 8 may further include a stuffing box 804 and a lip seal ring that seal the moving rod 8011 and the through hole 104, and the lip seal ring may be located between the moving rod 8011 and the stuffing box 804. The resistance to the movement of the moving rod 8011 is small, and the sealing effect is also good.

[0093] It should be noted that the descriptions of components such as rods and shafts passing through the mounting seat 1 in this application all refer to the mounting seat 1 being provided with holes corresponding to the rods and shafts, and the rods and shafts passing through the corresponding holes on the mounting seat 1 to pass through the mounting seat 1.

[0094] Figure 6 A cross-sectional view of an inner cover and a partial inner driving mechanism in some embodiments or certain embodiments of the present application is shown, Figure 7 FIG. 1 shows a top view of an inner cover and a local inner drive mechanism in some embodiments or certain embodiments of the present application, with reference to FIG. Figure 6 , 7 In some or certain embodiments, the inner cover 9 includes an inner cover body 901 and a hinge plate 902 fixed to one end of the inner cover body 901, and the hinge plate 902 is hinged to the inner shell 11. The inner cover 9 adopts this structure to facilitate the connection between the inner cover 9 and the inner shell 11, and also to reduce the interference that may be generated when the inner cover 9 rotates away from the inner shell 11. The inner shell 11 may also be provided with a corresponding protrusion hinged to the hinge plate 902.

[0095] In some or certain embodiments, the inner cover 9 may include an inner cover body 901, a leather cup 903 and a fixing ring 904. One end of the inner cover body 901 is fixed to the hinge plate 902, and the other end is provided with an inner cover circular groove 9011. The leather cup 903 is coaxially arranged in the inner cover circular groove 9011. The fixing ring 904 is pressed against the leather cup 903, and the fixing ring 904 and the inner cover body 901 are fastened together by bolts or screws.

[0096] In some or certain embodiments, a handle 905 may be further provided at one end of the inner cover 9 away from the inner housing 11 to facilitate opening of the inner cover 9.

[0097] In some or certain embodiments, the inner housing 11 is cylindrical and one end is fixed to the mounting seat 1, and the inner driving mechanism 10 includes:

[0098] The fixing frame 1001 is connected to the inner shell 11 .

[0099] The gear shaft 1002 is rotatably disposed on the fixing frame 1001 .

[0100] The clamping ring 1003 has an outer peripheral wall provided with a meshing tooth segment 10031 meshing with the gear shaft 1002. The clamping ring 1003 is movably arranged along the axial direction of the inner shell body 11, and one end is threadedly connected to the other end of the inner shell body 11. The inner peripheral wall of the clamping ring 1003 is provided with an annular clamping groove 10032 surrounding the inner cover 9 and used for clamping the inner cover 9.

[0101] The gear shaft 1002 rotates relative to the fixing frame 1001, which can drive the clamping ring 1003 to rotate, so that the clamping ring 1003 has a tendency to rotate relative to the inner housing 11. One end of the clamping ring 1003 is threadedly matched with the inner housing 11 and can move along the axial direction of the inner housing 11. The rotation tendency of the clamping ring 1003 can be converted into axial movement relative to the inner housing 11, so that the annular clamping groove 10032 on the inner peripheral wall of the clamping ring 1003 can move to the side wall to clamp the inner sealing cover 9, or the side wall is separated from the inner sealing cover 9. This design can improve the sealing performance of the inner cover.

[0102] It should be noted that the axial width of the annular clamping groove 10032 will be set large enough, so that when the clamping ring 1003 moves to a certain distance between the side wall and the inner cover 9, the annular clamping groove 10032 will leave enough space for the inner cover 9 to rotate and open the inner shell 11. The circumferential direction of the inner cover 9 away from the inner shell 11 can also be sloped, which is convenient for clamping and separation. The gear shaft 1002 can be rotatably connected to the fixed frame 1001 through structures such as bearings, and one end of the gear shaft 1002 can extend out of the fixed frame 1001, and the gear shaft 1002 can be driven to rotate manually or by a structure such as a motor. The meshing tooth segment 10031 can be a section of a rack arranged on the outer peripheral wall of the clamping ring 1003 along the circumference of the clamping ring 1003.

[0103] In some or certain embodiments, the outer peripheral wall of the clamping ring 1003 may also be provided with an arc plate 10033, and the arc plate 10033 may be installed with a sensor for measuring the position of the inner cover 9, and the outer shell 5 may also be provided with a sensor for monitoring the switch status of the outer cover 7.

[0104] The sensor is convenient for judging whether the inner and outer covers 7 are opened. If the sensor cooperates with the controller, the inner and outer covers 7 can be interlocked to improve the safety of the underwater parabolic device.

[0105] In some or certain embodiments, the inner housing 11 may be provided with two guide rods (not shown in the figure) spaced apart and extending axially along the inner housing 11, and the clamping ring 1003 is provided with guide holes (not shown in the figure) sleeved on the corresponding guide rods, so that the axial movement of the inner housing 11 can be achieved without rotating the clamping ring 1003.

[0106] In some or certain embodiments, an exhaust hole may be provided on the inner shell 11, and the stopper 1101 may be moved to block the exhaust hole or expose the exhaust hole.

[0107] The exhaust hole and the stopper 1101 can release the pressure inside the inner shell 11 and play a role in pressure equalization, thereby improving safety.

[0108] In some or certain embodiments, the movement of the stopper 1101 can be achieved by a mechanism (not shown in the figure) or a valve structure (not shown in the figure) embedded in the inner housing 11, which is convenient for realization and operation.

[0109] In some or certain embodiments, the shell (outer shell 5) containing the parabolic ball 4 may be provided with a pressure equalizing hole 508 penetrating the shell, and the underwater parabolic device further includes:

[0110] The medium carrier 12 is provided with a pressure liquid output end, and the pressure liquid output end is detachably connected to the pressure equalizing hole 508 .

[0111] The medium carrier 12 can input liquid into the pressure equalizing hole 508 of the outer shell 5 to increase the pressure inside the outer shell 5 to balance the pressure outside the outer shell 5 and the underwater vehicle, so as to facilitate the ejection of the object. The medium carrier 12 can be a pressure liquid bottle or a pressure container box.

[0112] Figure 8 A flow chart of an underwater parabolic method in some embodiments or certain embodiments of the present application is shown, with reference to Figure 8 Based on the same inventive concept, the present application also provides an underwater parabolic method, which can be implemented by using the underwater parabolic device as described above, including:

[0113] S101: Open a cover, put the object to be thrown into the shell corresponding to the cover, and let the object to be thrown fall into the parabolic trough of the parabolic ball.

[0114] S102: Close the opened cover.

[0115] S103: Rotate the parabolic ball until the parabolic trough turns away from the through hole and faces the cover corresponding to the housing.

[0116] S104: Open another cover to allow the ejecta to be ejected from the parabolic trough.

[0117] S105: Close all covers.

[0118] The structure and effect of the underwater parabolic device can be referred to above and will not be described here in detail. After the parabolic ball rotates to the parabolic trough away from the through hole and facing another channel, the garbage or waste in the parabolic trough can also be opposite to the cover of the shell where the parabolic ball is located. The cover of the shell where the parabolic ball is located is opened, and the garbage or waste in the parabolic trough can be thrown out from the opened cover. After the parabolic ball rotates, the cover corresponding to the shell where it is located is opened, which can reduce the influence of external pressure on the parabolic ball, and facilitate the rotation of the parabolic ball and the final parabolic throwing of the object to be thrown out.

[0119] It should be noted that the objects to be thrown out in the present application may be some waste or domestic garbage, but are not limited to domestic garbage and waste.

[0120] In some or certain embodiments, when the inner shell and the outer shell are provided with sensors, one of the covers can be selected to be opened after confirming that both covers are in a closed state.

[0121] In some or certain embodiments, after completing step S103, before opening another cover to throw the projectile from the parabolic trough, the underwater parabolic method further includes using a medium carrier to introduce a pressurized liquid into the shell where the parabolic ball is located to balance the pressure in the shell where the parabolic ball is located with the water pressure of the underwater vehicle. This is beneficial to prolonging the service life of the underwater parabolic device.

[0122] It should be noted that the objects to be ejected have their own gravity, and the underwater vehicle will also have changes in moving speed during navigation. When the cover of the shell where the parabolic ball is located is opened, the objects to be ejected in the parabolic trough can be separated from the underwater vehicle under the action of gravity or inertia.

[0123] In some or certain embodiments, the underwater parabolic method may further include that after all the covers are closed, the liquid in the shell where the parabolic ball is located can flow out through the pressure equalizing hole to improve safety. The liquid in the shell where the parabolic ball is located can be injected with air through the pressure equalizing hole in conjunction with a hydraulic pipeline or the like.
