Technical Field
[0001] The present invention relates to the field of lifeboats, and in particular to a control device for a lifeboat. Background Art
[0002] A lifeboat refers to a special rescue lifeboat provided on a ship for rescuing crew members when the ship is in distress. Generally, driving a lifeboat requires professional training. Otherwise, it is easy to have an accident when driving a lifeboat, resulting in the lifeboat capsizing. However, most people on the ship have not received professional training, and few people can operate a lifeboat. In case of an emergency, if there is no professional who can drive a lifeboat, many people may not be able to escape by the lifeboat, thus reducing the chance of escape. In order to escape, people who have not received professional training may drive a lifeboat to escape. However, due to lack of experience in driving a lifeboat, it is easy to cause the lifeboat to capsize during escape or rescue due to too large a steering angle. Even with professional training, it is also easy to cause the lifeboat to capsize when driving a lifeboat, thus threatening the lives of the people on the lifeboat. Summary of the Invention
[0003] The purpose of the present invention is to provide a control device for a lifeboat that can prevent the lifeboat from having too large a steering angle and avoid the lifeboat from capsizing.

The large gear can drive the long plate to swing through the short rod, and the swing of the long plate will cause the steering vane to swing, thereby guiding the water flow and achieving the purpose of adjusting the traveling direction of the lifeboat.
[0015] 2. When the operator turns the hand lever too far, the inclined panel will push the middle rod towards the direction close to the limit rod, thereby changing the position of the fulcrum when the long board rotates, enabling the operator to turn the hand lever more labor - savingly to adjust the driving direction of the lifeboat, saving the operator's physical strength, avoiding affecting the escape due to excessive physical strength consumption, and making the swing amplitude of the steering vane smaller to prevent the lifeboat from capsizing due to the operator turning the hand lever excessively.
[0016] 3. When the lifeboat is traveling too fast, the too - fast rotation speed of the propeller will push the large board to swing. The large board will make the middle rod move towards the direction close to the limit rod through the movable rod and the short board, thus changing the position of the fulcrum when the long board rotates, making the swing amplitude of the steering vane smaller. When the lifeboat is traveling too fast, it can avoid capsizing caused by the large - amplitude deflection of the steering vane due to improper operation by the operator, ensuring the safety of the people on the lifeboat.

DETAILED DESCRIPTION OF THE INVENTION
[0024] In order to make the objectives, technical solutions, and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0025] Embodiment 1: A control device for a lifeboat, as Figures 1 - 6 shown, comprising a lifeboat 100, a mounting frame 11, an engine 12, a propeller 13, a long rod 14, a steering vane 15, a direction adjusting component, and a steering adjusting component. The side of the lifeboat 100 is bolted to the mounting frame 11. The engine 12 is bolted to the inner side of the mounting frame 11. A propeller 13 is bolted to the output shaft of the engine 12. The lower side of the mounting frame 11 is rotatably connected to a long rod 14. The long rod 14 is vertically arranged. The bottom end of the long rod 14 is bolted to a steering vane 15. A direction adjusting component is provided on the mounting frame 11, and a steering adjusting component is provided on the direction adjusting component.
[0026] The surface of the steering vane 15 is an arc surface.
[0027] The direction adjusting component includes a hand lever 21, a stop lever 22, a small gear 23, a large gear 24, a short rod 25, a middle rod 26, and a long plate 27. The mounting frame 11 is rotatably connected to a hand lever 21. Two stop levers 22 are bolted to the upper side of the mounting frame 11. The stop levers 22 are vertically arranged. The lower end of the hand lever 21 is connected to a small gear 23 by a key. The lower side of the mounting frame 11 is rotatably connected to a large gear 24. The small gear 23 meshes with the large gear 24. The lower side of the large gear 24 is bolted to a short rod 25. The lower part of the mounting frame 11 is slidably connected to a middle rod 26. The lower part of the middle rod 26 is slidably connected to a long plate 27, and the long plate 27 can also rotate relative to the middle rod 26. The long plate 27 is slidably connected to the short rod 25 and the steering vane 15.
[0028] A chute is opened in the upper part of each stop lever 22.
[0029] The steering adjusting component includes an inclined panel 31, a short plate 32, a fixing plate 33, a limiting rod 331, and a return spring 34. The lower part of the hand lever 21 is bolted to an inclined panel 31. The inclined panel 31 is located above the small gear 23. A short plate 32 is bolted to the middle rod 26. The lower side of the mounting frame 11 is bolted to a fixing plate 33. A limiting rod 331 is fixedly connected to the fixing plate 33. The limiting rod 331 is slidably connected to the middle rod 26. A return spring 34 is connected between the fixing plate 33 and the middle rod 26 by a hook. The return spring 34 is used for the reset of the middle rod 26.
[0030] Both ends of the inclined panel 31 are provided with inclined surfaces.
[0031] Application method: When escaping in the lifeboat 100, the operator rotates the hand lever 21. The rotation of the hand lever 21 drives the rotation of the small gear 23, and the rotation of the small gear 23 drives the rotation of the large gear 24. Driving the large gear 24 to rotate through the small gear 23 is more labor-saving and convenient for the operator to operate the lifeboat 100. The rotation of the large gear 24 drives the rotation of the short rod 25, and the rotation of the short rod 25 drives the swing of the long plate 27. The long plate 27 will swing with the middle rod 26 as the fulcrum. The swing of the long plate 27 will cause the steering vane 15 to swing, and the swing of the steering vane 15 will guide the water flow, so as to achieve the purpose of adjusting the driving direction of the lifeboat 100. The rotation of the hand lever 21 drives the rotation of the inclined panel 31. When the angle of rotation of the hand lever 21 by the operator is too large, the inclined panel 31 will contact the short plate 32 and push the short plate 32 to swing. The swing of the short plate 32 will push the middle rod 26 to move towards the direction close to the limit rod 331, and the return spring 34 will be compressed. The movement of the middle rod 26 towards the direction close to the limit rod 331 will change the position of the fulcrum when the long plate 27 rotates, enabling the operator to rotate the hand lever 21 more labor-savingly to adjust the driving direction of the lifeboat 100, saving the operator's physical strength, avoiding affecting the escape due to excessive physical strength consumption, and making the swing amplitude of the side of the long plate 27 close to the limit rod 331 smaller, so that the swing amplitude of the steering vane 15 can be smaller, to prevent the lifeboat 100 from capsizing due to the operator's excessive rotation of the hand lever 21; when the inclined panel 31 is separated from the short plate 32, the reset of the return spring 34 will drive the middle rod 26 to reset towards the direction away from the limit rod 331, and the reset of the middle rod 26 will drive the short plate 32 to reset.
[0032] Embodiment 2: On the basis of Embodiment 1, as Figures 3 - 6 shown, it further includes an auxiliary steering adjustment component. The auxiliary steering adjustment component is arranged on the lower side of the mounting frame 11. The auxiliary steering adjustment component includes a limit block 41, a movable rod 42, a middle plate 43, a large plate 44 and a torsion spring 45. The lower side of the mounting frame 11 is bolted with the limit block 41. The limit block 41 is slidably connected with the movable rod 42. One end of the movable rod 42 is fixedly connected with the short plate 32. The lower side of the mounting frame 11 is bolted with the middle plate 43. The middle plate 43 is rotatably connected with the large plate 44. The large plate 44 contacts the other end of the movable rod 42. A torsion spring 45 is connected between the middle plate 43 and the large plate 44 by a hook. The torsion spring 45 is used for the reset of the large plate 44.
[0033] When the rotation speed of the propeller 13 is too fast during driving, the propeller 13 rotates in the water and pushes the water flow to move. When the propeller 13 pushes the water flow back in the reverse direction, a reaction force opposite to the moving direction will be generated. This reaction force will push the large plate 44 to swing away from the propeller 13, the torsion spring 45 is twisted, the swing of the large plate 44 will push the movable rod 42 to move away from the long plate 27, the movement of the movable rod 42 will drive the short plate 32 to move, the movement of the short plate 32 will drive the middle rod 26 to move, the return spring 34 is compressed, and the movement of the middle rod 26 towards the limiting rod 331 will change the position of the fulcrum when the long plate 27 rotates, thereby reducing the swing amplitude of the steering vane 15. When the lifeboat 100 is traveling too fast, it can prevent the steering vane 15 from deflecting greatly due to improper operation of the operator, resulting in capsizing, and ensure the safety of the personnel on the lifeboat 100; when the rotation speed of the propeller 13 slows down, the torsion spring 45 will reset and drive the large plate 44 to reset. The large plate 44 will be disengaged from the movable rod 42. The reset of the return spring 34 will drive the middle rod 26 to reset away from the limiting rod 331. The reset of the middle rod 26 will drive the short plate 32 to reset, and the reset of the short plate 32 will drive the movable rod 42 to reset.
[0034] Embodiment 3: On the basis of Embodiment 2, as Figure 2 shown, it further includes a friction reminder component. The friction reminder component is arranged on the stop rod 22. The friction reminder component includes a friction ring one 51 and a friction ring two 52. One of the stop rods 22 is slidably connected with the friction ring one 51 on its chute, and the other stop rod 22 is slidably connected with the friction ring two 52 on its chute.
[0035] When the rotation amplitude of the hand rod 21 is too large, it will contact the friction ring one 51 or the friction ring two 52. There is friction when the hand rod 21 contacts the friction ring one 51 or the friction ring two 52. The friction will play a hindering role on the hand rod 21, making it more laborious to rotate the hand rod 21 when the rotation amplitude is too large, so as to achieve the effect of reminding the operator and preventing the operator from rotating the hand rod 21 excessively to prevent the lifeboat 100 from capsizing.
[0036] Embodiment 4: On the basis of Embodiment 3, as Figures 1 - 6 shown, it further includes an inclined side plate 61 and a top rod 62. The upper side of the movable rod 42 is connected with the inclined side plate 61 by bolts. The inclined side plate 61 is slidably connected with the mounting frame 11. A top rod 62 is connected between the lower sides of the friction ring one 51 and the friction ring two 52 by bolts. The lower end of the top rod 62 contacts the inclined side plate 61.
[0037] When the rotation amplitude of the hand lever 21 is too large or the traveling speed of the lifeboat 100 is too fast, the movement of the movable lever 42 will drive the movement of the bevel plate 61. The movement of the bevel plate 61 will contact the ejector rod 62 and push the ejector rod 62 to move upward. The upward movement of the ejector rod 62 will drive the first friction ring 51 and the second friction ring 52 to move upward. The upward movement of the first friction ring 51 and the second friction ring 52 will block the hand lever 21 and prevent the hand lever 21 from rotating excessively, better preventing the lifeboat 100 from capsizing; the reset of the movable lever 42 will drive the reset of the bevel plate 61. The reset of the bevel plate 61 will disengage from the ejector rod 62. The ejector rod 62 will be reset downward under the action of gravity. The reset of the ejector rod 62 will drive the reset of the first friction ring 51 and the second friction ring 52.
[0038] It further includes a filter screen 70. The side of the mounting frame 11 is connected with the filter screen 70 by bolts. The filter screen 70 is used to block sundries in the water from entering.
