Description

Technical Field

[0001] The invention relates to the field of manipulator jettisoning, and in particular to a safe jettisoning system for underwater vehicles. Background Art

[0002] As the main tool for human exploration of the ocean, underwater vehicles are widely used in military and civilian fields such as unmanned island patrols, seafloor topography mapping, offshore drilling platforms, and offshore wind power operation and maintenance. As the requirements for underwater detection operations become increasingly complex and diverse, higher requirements are placed on the long-flight, safe, and reliable navigation performance indicators of underwater vehicles.

[0003] Since the surface of underwater vehicles is mostly a streamlined structure, in order to facilitate the underwater vehicles to be jettisoned into the water, the current market has abandoned the method of manual jettisoning. With the rapid development of modern manipulator and mechanical arm technology, of course, the underwater vehicle jettisoning work has been completed by manipulators. The underwater vehicle is clamped by the manipulator and placed in the water area to be navigated. When recovering, the underwater vehicle is grasped by the manipulator and placed on the carrier. Therefore, the manipulator clamping is more accurate and quick.

[0004] However, the loading-dropping method of most manipulators on the market still exists in actual use. Since the surface of underwater vehicles is mostly streamlined, general manipulators are prone to slipping when grasping, and the underwater vehicle is prone to falling. At the same time, traditional manipulators are mostly single-model underwater vehicles that are matched with manipulator parts of a single shape for loading, which results in poor flexibility of traditional manipulators and poor compatibility with different underwater vehicles.

[0005] Therefore, it is necessary to provide an underwater vehicle safe jettisoning system to solve the above technical problems. Summary of the invention

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] The invention provides a safe jettisoning system for an underwater vehicle.

[0044] First embodiment:

[0045] See also Figures 1 to 6 , an underwater vehicle safety jettisoning system, comprising a base 1 and a clamping mechanism 3;

[0046] A turntable 6 is installed above the base 1, and a first flip motor 7 is installed on the outer wall of the turntable 6 by bolts. A flip arm 8 is connected to the output shaft keyway of the first flip motor 7, and a second flip motor 9 is installed on the upper outer wall of the flip arm 8 by bolts. A flip arm 10 is installed at the output end of the second flip motor 9, and a universal head 11 is installed at the front end of the flip arm 10;

[0047] See also Figure 1 and Figure 2 : In actual use, the user can start the turntable 6, which can perform a 360-degree free rotation movement, so that the clamping mechanism 3 can be controlled to unload or reset the aircraft body 12. The user starts the first flipping motor 7 to control the flipping movement of the flip arm 8, and starts the second flipping motor 9 to control the flipping movement of the flip arm 10. At the same time, the universal head 11 rotates in two directions, horizontally and vertically, which can control the clamping mechanism 3 to perform universal movement.

[0048] The clamping mechanism 3 includes a mounting plate 31 fixed to the bottom end of the universal head 11, a driving motor 32 is mounted on the outer wall of the mounting plate 31 by bolts, a driving gear 33 is connected to the output shaft keyway of the driving motor 32, two first flaps 34 are rotatably connected inside the mounting plate 31, two second flaps 37 are rotatably connected inside the mounting plate 31 and below the two first flaps 34, a clamping plate 38 is rotatably connected to the outer ends of the two first flaps 34, and a first gear 35 and a second gear 36 are fixed inside the upper ends of the two first flaps 34, respectively;

[0049] See also Figure 3: The user can start the drive motor 32 to control the drive gear 33 to rotate counterclockwise. The counterclockwise rotating drive gear 33 will engage the transmission control first gear 35 to engage the second gear 36 to rotate, thereby driving the first flap 34 to move, retract and open. When the two first flaps 34 are opened in conjunction, the two clamps 38 will follow the movement of the first flap 34 and the second flap 37 to unfold. When the first flap 34 is closed, the two clamps 38 will also close synchronously.

[0050] A stabilizing assembly 4 is installed on the opposite side of the two clamps 38, and the stabilizing assembly 4 includes a positioning plate 41. A plurality of mounting holes 46 are opened inside the positioning plate 41, and a return spring 47 is fixed inside the plurality of mounting holes 46. A stabilizing pin 42 is fixed at the front end of the plurality of return springs 47. Two mounting pins 43 are fixed on the back of the positioning plate 41. The interiors of the two mounting pins 43 pass through the interiors of the clamps 38 and are threadedly connected with a first fastening bolt 44 and a second fastening bolt 45.

[0051] See also Figure 4 and Figure 6 When the two clamps 38 are closed to clamp the aircraft body 12, the first thing to come into contact with the aircraft body 12 is the stabilizing pin 42. Since the surface of the aircraft body 12 is an uneven streamlined structure, the stabilizing pin 42 that first comes into contact with the streamlined position will slide inside the mounting hole 46 and change to adapt to the streamlined shape of the surface of the aircraft body 12.

[0052] The first gear 35 and the second gear 36 mesh with each other, and the driving gear 33 and the first gear 35 mesh with each other.

[0053] The axis of the driving gear 33 is rotatably connected to the inner wall of the mounting plate 31 , and the lower ends of the two second flaps 37 are rotatably connected to the inside of the two clamping plates 38 .

[0054] The outer walls of the plurality of stabilizing pins 42 are slidably connected to the inner walls of the plurality of mounting holes 46 , and the positioning plate 41 forms a detachable structure with the clamping plate 38 through the cooperation between the mounting pin 43 and the first fastening bolt 44 and the second fastening bolt 45 .

[0055] Understandable: Combined Figure 5 It can be seen that when the user installs the positioning plate 41, the installation pin 43 outside the positioning plate 41 can be inserted into the clamping plate 38, and then the first fastening bolt 44 and the second fastening bolt 45 need to be aligned with the installation pin 43 in turn. After alignment, the first fastening bolt 44 and the second fastening bolt 45 are rotated, and the positioning plate 41 and the clamping plate 38 are installed.

[0056] This embodiment: Compared with the traditional dumping design, this case adopts a manipulator to dump the aircraft body 12, and adopts a freely rotating turntable 6 to match the two-stage flipping mechanism, and can control the clamping mechanism 3 to perform universal motion. Therefore, such a design effectively improves the flexibility of the clamping mechanism 3, which is more conducive to dumping on the water surface. At the same time, multiple stabilizing pins 42 are provided to follow the streamlined surface of the aircraft body 12 for adaptive clamping adjustment, which can ensure that the clamping mechanism 3 can cope with clamping aircraft bodies 12 of different models and shapes, and at the same time, the force is more uniform and the contact surface is maximized, which can prevent the aircraft body 12 from falling off during dumping.

[0057] Second embodiment:

[0058] See also Figure 4 , Figure 7 and Figure 8 A negative pressure assembly 5 is installed inside the positioning plate 41, and the negative pressure assembly 5 includes a negative pressure machine 51 installed on the outer wall of the splint 38. Two hoses 52 are sealed and installed at the output end of the negative pressure machine 51. Two limiting tubes 53 are installed inside the splint 38. Limiting springs 58 are fixed inside the two limiting tubes 53. Negative pressure tubes 54 are fixed at the outer ends of the two limiting springs 58. Rubber rings 55 are fixed at the front ends of the two negative pressure tubes 54. Through holes 56 are opened inside the two negative pressure tubes 54. A conducting tube 57 is fixed on the top of the two limiting tubes 53.

[0059] See also Figure 4 , Figure 7 and Figure 8 : In the first embodiment, the front end rubber ring 55 of the negative pressure tube 54 inside the positioning plate 41 will first contact the outer wall of the aircraft body 12, and then with the movement of the stabilizing pin 42, the negative pressure tube 54 will follow the motion control limit spring 58 to be compressed inside the limit tube 53. When the clamping plate 38 is clamped to the limit, the through hole 56 in the negative pressure tube 54 will pass through the conducting tube 57. When the through hole 56 and the conducting tube 57 are staggered, the negative pressure machine 51 will connect the negative pressure tube 54 through the hose 52 to generate suction to negatively pressure the aircraft body 12 and adsorb it on the clamping plate 38.

[0060] The outer walls of the two negative pressure tubes 54 are slidably connected to the inner walls of the two limiting tubes 53 , the inner diameter of the through hole 56 is the same as the inner diameter of the conducting tube 57 , and the outlet ends of the two hoses 52 are sealed and installed with the two conducting tubes 57 .

[0061] This embodiment: Compared with the traditional clamping design, this case is designed with a negative pressure tube 54 that can move with the stabilizing pin 42, so that when the through hole 56 moves with the negative pressure tube 54 to the position of the conducting tube 57, and the through hole 56 and the conducting tube 57 are staggered, the negative pressure machine 51 will be started to generate suction so that the negative pressure tube 54 can stably adsorb the clamped aircraft body 12, and in the process of moving, the larger the staggered holes, the greater the suction force. Such a design plays a secondary stabilization function, and the negative pressure adsorption method does not damage the surface of the aircraft body 12, which can ensure that the aircraft body 12 can be safer during load jettisoning.

[0062] Third embodiment:

[0063] See also Figure 1 , Figure 2 , Fig. 9 and Fig.10 , further comprising an aircraft body 12 and a carrier plate 2, a connection plate 13 is fixedly provided on the upper surface of the carrier plate 2, an elastic contact 14 is installed on the outer wall of the turntable 6, a pressure sensor 15 is installed inside the connection plate 13, and the pressure sensor 15 is electrically connected to a central processing unit 16 through a wire;

[0064] A signal frequency meter 17 is installed inside the central processing unit 16 . The signal frequency meter 17 is electrically connected to a Beidou positioning module 18 via a wire. The Beidou positioning module 18 is electrically connected to a radio transmitter 19 via a wire.

[0065] The inner wall of the connecting plate 13 is in contact with the outer wall of the turntable 6 , and the pressure sensor 15 , the signal frequency meter 17 , the Beidou positioning module 18 and the radio transmitting end 19 are electrically connected in series.

[0066] See also Figure 1 and Figure 2 : The turntable 6 can rotate freely when the aircraft body 12 is thrown, and if it needs to be reset, it needs to be rotated to Figure 2 The position in.

[0067] See also Fig. 9 When the turntable 6 rotates and resets, the elastic contact 14 will rotate along with the rotation of the turntable 6, and the elastic contact 14 will rotate to the inside of the connecting plate 13 and squeeze the pressure sensor 15 under force.

[0068] See also Fig.10 : When the pressure sensor 15 receives a pressure signal, it converts the pressure signal into an electrical signal to start the signal frequency meter 17. The signal frequency meter 17 is mainly used to detect the signal frequency of the Beidou positioning module 18 at this time, because the central processor 16 and the locator inside the aircraft body 12 are connected by radio;

[0069] Secondly, the entire Beidou positioning module 18 is divided into B1 segment and B2 segment, and the B1 segment is also divided into Bl1 and BlC. If the frequency detected by the signal frequency meter 17 is 1561.098 MHz, it will be automatically identified as Bl1 segment, and the radio transmitter 19 will transmit the signal to the aircraft body 12;

[0070] When the frequency detected by the signal frequency meter 17 is 1575.42 MHz, it will be automatically identified as in the B1C segment, and the radio transmitter 19 will transmit the signal to the aircraft body 12;

[0071] When the frequency detected by the signal frequency meter 17 is 1176.45 MHz, it will be automatically identified as in the B2 segment, and the radio transmitter 19 will transmit the signal to the aircraft body 12.

[0072] This embodiment: This case is designed to recognize all Beidou positioning frequencies available on the market, and when identifying the current frequency, the radio transmitter 19 will transmit the current frequency. Therefore, such a design can be used for multi-frequency connection, and the radio connection between the aircraft body 12 and the carrier plate 2 is always guaranteed, whether in navigation or return, the most accurate frequency band can be guaranteed for positioning.

[0073] Please refer to Figures 1 to 10 The working principle of the underwater vehicle safety jettisoning system provided by the present invention is as follows:

[0074] Step S1: In actual use, the user can start the turntable 6, which can perform a 360-degree free rotation movement, so that the clamping mechanism 3 can be controlled to dump or reset the aircraft body 12. The user starts the first flip motor 7 to control the flip arm 8 to flip, and starts the second flip motor 9 to control the flip arm 10 to flip. At the same time, the universal head 11 rotates in two directions, horizontally and vertically, so that the clamping mechanism 3 can be controlled to perform universal movement. The driving motor 32 controls the driving gear 33 to rotate counterclockwise. The counterclockwise rotating driving gear 33 will mesh with the transmission to control the first gear 35 to mesh with the second gear 36 to rotate, so that the first flap 34 can be driven to move, retract and open. When the two first flaps 34 are opened in linkage, the two clamps 38 follow the movement of the first flap 34 and the second flap 37 to unfold. When the first flap 34 is closed, the two clamps 38 will also be closed synchronously.

[0075] Step S2: The front rubber ring 55 of the negative pressure tube 54 will first contact the outer wall of the aircraft body 12, and then as the stabilizing pin 42 moves, the negative pressure tube 54 will follow the motion control limit spring 58 to be compressed inside the limit tube 53. When the clamping plate 38 is clamped to the limit, the through hole 56 in the negative pressure tube 54 will pass through the conducting tube 57. When the through hole 56 and the conducting tube 57 are interlaced, the negative pressure machine 51 will connect the negative pressure tube 54 through the hose 52 to generate suction to negatively pressure the aircraft body 12 and adsorb it on the clamping plate 38.

[0076] Step S3: When the turntable 6 rotates and resets, the elastic contact 14 rotates along with the rotation of the turntable 6, and the elastic contact 14 rotates to the inside of the connecting plate 13 and is pressed against the pressure sensor 15;

[0077] When the pressure sensor 15 receives a pressure signal, it converts the pressure signal into an electrical signal to start the signal frequency meter 17. The signal frequency meter 17 is mainly used to detect the signal frequency of the Beidou positioning module 18 at this time, because the central processor 16 and the locator inside the aircraft body 12 are connected by radio;

[0078] Secondly, the entire Beidou positioning module 18 is divided into B1 segment and B2 segment, and the B1 segment is also divided into Bl1 and BlC. If the frequency detected by the signal frequency meter 17 is 1561.098 MHz, it will be automatically identified as Bl1 segment, and the radio transmitter 19 will transmit the signal to the aircraft body 12;

[0079] When the frequency detected by the signal frequency meter 17 is 1575.42 MHz, it will be automatically identified as in the B1C segment, and the radio transmitter 19 will transmit the signal to the aircraft body 12;

[0080] When the frequency detected by the signal frequency meter 17 is 1176.45 MHz, it will be automatically identified as in the B2 segment, and the radio transmitter 19 will transmit the signal to the aircraft body 12.

[0081] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
