Description

Technical Field

[0001] This utility model relates to the field of unmanned surface vessel (USV) technology, specifically an automatic launching device for simulating maritime platform accidents. Background Technology

[0002] Autonomous underwater vehicles (AUVs) are a type of unmanned underwater vehicle (UUV). UUV technology is not new in either military or civilian applications; its development began in the 1950s. Early applications were primarily for offshore oil and gas development, while military applications mainly involved salvaging lost underwater weapons (such as torpedoes). Later, it saw significant development as a mine-clearing tool in mine warfare. In the late 1980s, with the rapid advancements in computer technology, artificial intelligence, microelectronics, small navigation equipment, command and control hardware, and logic and software technology, autonomous underwater vehicles experienced substantial development.

[0003] When designing and improving existing unmanned surface vessels (USVs), it is necessary to conduct launch tests, especially tests on the launch status of USVs in the event of a maritime accident. This is to test the launch status of USVs under specific circumstances. However, current devices for simulating launch scenarios only involve lowering USVs and do not have launch devices for simulating maritime accident scenarios. Utility Model Content

[0004] The purpose of this invention is to provide an automatic launching device for unmanned surface vessels that simulates accidents on offshore platforms, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic launching device for unmanned surface vessels (USVs) simulating offshore platform accidents, comprising a base, a support platform, and a first hydraulic cylinder.

The two connecting blocks are respectively fixedly connected to the rear side of the two push plates. The connecting blocks are moved by starting the third hydraulic cylinder, and then the connecting blocks drive the push plates and L-shaped plates to move during the movement, so that the L-shaped plates push the unmanned surface vessel to move, which facilitates the lowering test.

[0009] Preferably, a second hydraulic cylinder is fixedly connected to the top of the base, a sliding sleeve is fixedly connected to the output end of the second hydraulic cylinder, a connecting plate is fixedly connected inside the sliding sleeve, a first motor is fixedly connected to both ends of the connecting plate, a second threaded rod is fixedly connected to the output ends of the two first motors, a support arm is fixedly connected to both ends of the bottom of the connecting plate, a bracket is fixedly connected to the bottom of the two support arms, a support block is fixedly connected to one side of the top of the two brackets, and the two second threaded rods are rotatably connected to the two support blocks respectively to support the second threaded rods and improve the stability of the second threaded rods.

[0010] Preferably, a movable sleeve is sleeved and slidably connected to the outside of the second hydraulic cylinder, and the bottom ends of the two brackets are fixedly connected to the two sides of the movable sleeve respectively. Guide grooves are opened on both sides of the second hydraulic cylinder, and guide wheels are rotatably connected to both sides inside the movable sleeve.

[0011] Preferably, each of the two second threaded rods is threadedly connected to a movable plate on its outer side, and a guide sleeve is fixedly connected to the top of each of the two movable plates. Each of the two support arms is fixedly connected to a limit rod inside, and the two limit rods pass through the two movable plates respectively and are slidably connected to the two movable plates to support and limit the movable plates.

[0012] Preferably, guide rails are fixedly connected to both sides of the top of the base. A third threaded rod is rotatably connected inside each of the two guide rails. A moving block is slidably connected inside each of the two guide rails. The two third threaded rods pass through the two moving blocks and are threadedly connected to the two moving blocks.

[0014] Preferably, a steel cable is wound around and fixedly connected to the outer side of the winding wheel. The steel cable passes through the guide sleeve and is slidably connected to the guide sleeve. Pull plates are fixedly connected to both ends of the cross plate. Connecting rings are fixedly connected to the bottom rear side of the two pull plates. The top ends of the two steel cables are fixedly connected to the two connecting rings respectively. When the winding wheel rotates, the steel cable is wound and unwound, thereby pulling the connecting rings and pull plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application causes the fixed plate to lift the support ball and support sleeve. During the lifting of the support sleeve, the connecting frame is lifted, and during the lifting of the connecting frame, the horizontal plate is lifted. When the horizontal plate rises, the support plates on both sides rise, thereby lifting the unmanned surface vessel (USV) upward. During the up-and-down movement, the USV moves back and forth, simulating the surging process of sea waves. Then, the first threaded rod rotates, causing the fixed plate to rotate. During the rotation of the fixed plate, the top rod rotates. When the top rod rotates, it causes multiple arc-shaped plates to rotate, thereby causing the support plate to float up and down. This causes the support plate to shake the support sleeve and connecting frame, and finally causes the horizontal plate and the two support plates to shake back and forth. The USV's reciprocating shaking simulates the situation when an accident occurs on an offshore platform.

[0017] 2. This application uses a second motor to start, which drives the winding wheel to rotate, thereby moving the steel cable. The steel cable pulls the connecting ring and the pull plate, causing them to deflect. By controlling the different pulling distances and speeds of the steel cables on both sides, the horizontal plate floats. Two third motors are started, which drive two third threaded rods to rotate. When the two third threaded rods rotate, they drive the moving block to move inside the guide rail. As the moving block moves, it drives the winding wheel to move, and the winding wheel pulls the bottom end of the steel cable to move, changing the direction of the steel cable movement. This, combined with the support plate, improves the simulation effect and increases the simulation states, thereby expanding the simulation of the unmanned surface vessel's launch and increasing the experimental data.

[0018] 3. This application enables the second threaded rod to lift the moving plate and guide sleeve. Because the steel cable slides inside the guide sleeve, the guide sleeve changes the guiding direction of the steel cable during movement. Simultaneously, the first motor starts, driving the second threaded rod to rotate, which in turn moves the moving plate. The moving plate then moves the guide sleeve horizontally, thereby adjusting the guiding angle and direction of the steel cable. This enhances the simulation scheme and allows for precise adjustment of the horizontal plate and the unmanned surface vessel's support position during the change of guiding angle and direction, improving the accuracy and flexibility of the simulation experiment. It also enables the simulation of various states of the unmanned surface vessel's launch, providing strong support for the collection and analysis of experimental data. Attached Figure Description

A support sleeve 11 is sleeved on the outside of the support ball 10. A support plate 15 is fixedly connected to the outside of the support sleeve 11.

The slide plate 22 is slidably connected to the inside of the slide rail 21 and is adapted to the slide rail 21. The rear sides of the two support plates 17 are fixedly connected to the third hydraulic cylinders 51. The output ends of the two third hydraulic cylinders 51 are fixedly connected to the connecting blocks 52. The two connecting blocks 52 are fixedly connected to the rear sides of the two push plates 19 respectively. The third hydraulic cylinders 51 are started to drive the connecting blocks 52 to move. Then, the connecting blocks 52 drive the push plates 19 and L-shaped plates 20 to move during the movement, so that the L-shaped plates 20 push the unmanned boat to move, which is convenient for the lowering test.

[0037] A second hydraulic cylinder 23 is fixedly connected to the top of the base 1. A sliding sleeve 24 is fixedly connected to the output end of the second hydraulic cylinder 23. A connecting plate 25 is fixedly connected inside the sliding sleeve 24. A first motor 26 is fixedly connected to both ends of the connecting plate 25. A second threaded rod 27 is fixedly connected to the output ends of both first motors 26. Support arms 29 are fixedly connected to both ends of the bottom of the connecting plate 25. A bracket 28 is fixedly connected to the bottom of both support arms 29. A support block 30 is fixedly connected to one side of the top of both brackets 28. The two second threaded rods 27 are rotatably connected to the two support blocks 30 respectively to support the second threaded rods 27 and improve their stability. A movable sleeve 34 is sleeved and slidably connected to the outside of the second hydraulic cylinder 23. The bottom ends of the two brackets 28 are fixedly connected to both sides of the movable sleeve 34. The second hydraulic cylinder 23 has guide grooves 35 on both sides. The movable sleeve 34 has guide wheels 36 rotatably connected to both sides inside. The two guide wheels 36 are slidably connected to the two guide grooves 35 to guide the guide wheels 36, thereby supporting the movable sleeve 34 and improving the stability of the movable sleeve 34 when it moves. The two second threaded rods 27 are threadedly connected to the outer sides of the movable plates 31. The tops of the two movable plates 31 are fixedly connected to the guide sleeves 32. The two support arms 29 are fixedly connected to the inside of the limit rods 33. The two limit rods 33 pass through the two movable plates 31 and are slidably connected to the two movable plates 31 to support and limit the movable plates 31.

[0038] Guide rails 37 are fixedly connected to both sides of the top of the base 1. A third threaded rod 38 is rotatably connected inside each guide rail 37. Moving blocks 39 are slidably connected inside each guide rail 37. The two third threaded rods 38 pass through and are threadedly connected to the two moving blocks 39 respectively. Guide plates 40 are integrally formed on both sides of the inside of each guide rail 37, and the two guide plates 40 are adapted to the sides of the moving blocks 39 respectively. A third motor 46 is fixedly connected to one end of each guide rail 37. The output end of the third motor 46 is fixedly connected to the third threaded rod 38. The third motor 46 starts and drives the third threaded rod 38 to rotate, thus moving the moving blocks 39. A winding wheel 42 is rotatably connected inside each moving block 39. The moving blocks 39 are fixedly connected to both sides of each other. A vertical plate 41 is fixedly connected, and a first guide wheel 44 and a second guide wheel 45 are fixedly connected between the tops of the two vertical plates 41. A second motor 43 is fixedly connected to one side of the moving block 39. The output end of the second motor 43 is fixedly connected to the take-up wheel 42. The take-up wheel 42 is rotated by the second motor 43. A steel cable 47 is wound around and fixedly connected to the outside of the take-up wheel 42. The steel cable 47 passes through the guide sleeve 32 and is slidably connected to the guide sleeve 32. Pull plates 48 are fixedly connected to both ends of the horizontal plate 13. A connecting ring 49 is fixedly connected to the rear bottom of the two pull plates 48. The top ends of the two steel cables 47 are fixedly connected to the two connecting rings 49 respectively. When the take-up wheel 42 rotates, it winds and unwinds the steel cables 47, thereby pulling the connecting rings 49 and the pull plates 48.

[0039] When using this solution, the device is placed on one side of the test pool by placing the unmanned surface vessel test machine on top of the support plate 17 and positioning the unmanned surface vessel above the pool.

[0040] Example 1: The fourth motor 50 is started, causing the rotating sleeve 4 to rotate. During rotation, the limiting plates 7 on both sides of the rotating sleeve 4 limit the two limiting grooves 8, thereby causing the first threaded rod 5 to rotate. Because the first threaded rod 5 is simultaneously threadedly connected to the threaded sleeve 6, it rises inside the threaded sleeve 6. This rise causes the fixing plate 9 to rise, which in turn causes the support ball 10 and the support sleeve 11 to rise. During the rise of the support sleeve 11, the connecting frame 12 rises, and during the rise of the connecting frame 12, the connecting frame 12... The horizontal plate 13 rises, which in turn drives the support plates 17 on both sides to rise, thereby lifting the unmanned surface vessel (USV) upward. During the up-and-down movement, the USV moves back and forth, simulating the surging process of sea waves. Then, the first threaded rod 5 rotates, which drives the fixed plate 9 to rotate. During the rotation of the fixed plate 9, the top rod 14 rotates. When the top rod 14 rotates, it drives multiple arc-shaped plates 16 to rotate, thereby causing the support plate 15 to float up and down. This causes the support plate 15 to shake the support sleeve 11 and the connecting frame 12, ultimately causing the horizontal plate 13 and the two support plates 17 to shake back and forth. The USV's reciprocating shaking simulates the situation when an accident occurs on an offshore platform.

[0041] Example 2: The computer controls the forward and reverse rotation of the third motor 46 to drive the moving block 39 to move. The steel cable 47 stretches the pull plate 48, thereby supporting the horizontal plate 13 and the pull plate 48. The computer controls the support direction of the horizontal plate 13, so that the horizontal plate 13 supports the support plate 17, thereby supporting the unmanned surface vessel. The second motor 43 is started, causing the second motor 43 to drive the winding wheel 42 to rotate, thereby driving the steel cable 47 to move. The steel cable 47 pulls the connecting ring 49 and the pull plate 48 to deflect, controlling the pulling distance of the steel cables 47 on both sides. The different speeds cause the horizontal plate 13 to float, which is activated by two third motors 46, thereby driving two third threaded rods 38 to rotate. When the two third threaded rods 38 rotate, they drive the moving block 39 to move inside the guide rail 37. When the moving block 39 moves, it drives the winding wheel 42 to move, and the winding wheel 42 pulls the bottom end of the steel cable 47 to move, changing the direction of the movement of the steel cable 47. This, together with the support plate 15, improves the simulation effect and increases the simulation state, thereby expanding the simulation of the unmanned surface vessel's launch and increasing the experimental data.

[0042] Example 3: The second hydraulic cylinder 23 is activated, causing it to rise, which in turn raises the sliding sleeve 24 and connecting plate 25. As the connecting plate 25 rises, it drives the two first motors 26 to rise, which in turn raises the two second threaded rods 27 and the support block 30. The second threaded rods 27 then raise the moving plate 31 and guide sleeve 32. Because the steel cable 47 slides inside the guide sleeve 32, the guide sleeve 32 changes the guiding direction of the steel cable 47 as it moves. Simultaneously, the first motors 26 activate, causing the second threaded rods 27 to rotate, which in turn moves the moving plate 31. The moving plate 31 then moves the guide sleeve 32 horizontally, thereby adjusting the guiding angle and direction of the steel cable 47. This increases the simulation options and allows for precise adjustment of the horizontal plate 13 and the unmanned surface vessel's support position during the adjustment of the guiding angle and direction, improving the accuracy and flexibility of the simulation experiment. It achieves multiple simulation states of the unmanned surface vessel's launch, providing strong support for the collection and analysis of experimental data.
