Description

Technical Field

[0001] This invention relates to the field of navigation simulation device technology, and in particular to a navigation simulation device. Background Technology

[0002] Nautical simulation devices are widely used for crew operation training and nautical environment simulation operations. However, the existing device structural design has significant shortcomings. They generally ignore the comprehensive effects of dynamic changes in sea waves on the ship's hull, and cannot reflect the linkage between real-time wave fluctuations and the lateral forces of water flow on the ship's attitude, resulting in poor simulation fidelity. At the same time, the existing support and constraint structures are too rigid, with too many overall constraints and limits. They can only complete the limited swaying under navigation conditions and cannot simulate the free swaying effect of the ship under water flow and surface disturbance when it is stationary. The action modes are monotonous and differ greatly from the force and motion state of a real ship on the water surface, significantly reducing the immersion and realism of the navigation simulation and failing to fully cover the simulation needs of different navigation conditions. Summary of the Invention

[0003] The main objective of this invention is to provide a maritime simulation device that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A maritime simulation device includes a simulation pool, a support frame fixedly mounted in the middle of the simulation pool, a connecting assembly mounted in the middle of the support frame, a switching component mounted on the connecting assembly, a simulator fixedly mounted on the lower side of the connecting assembly, three sets of wave simulation components mounted on one side and the front side of the simulation pool, and a connecting column fixedly mounted in the lower middle of the support frame, a connecting cover fixedly mounted on the lower end of the connecting column, several sets of external sliding grooves formed on the inner wall of the connecting cover, and a rotating ball movably mounted on the inner side of the connecting cover. The outer side of the moving ball is provided with an inner groove corresponding to several sets of outer grooves. A connecting ring is fitted between the rotating ball and the inner wall of the connecting cover. A ball bearing is provided on the inner side of the connecting ring corresponding to several sets of outer and inner grooves. A disc is fixedly installed at the lower end of the connecting cover. A fixing post is fixedly installed at the lower end of the rotating ball. A fixing sleeve is fixedly installed on the outer side of the fixing post. Four sets of right-angle rods are fixedly installed on the outer side of the fixing sleeve. A first fixing seat is fixedly installed at the upper end of the four sets of right-angle rods and the lower end of the disc. A spring is fixedly connected between the disc and the corresponding first fixing seat on the right-angle rod.

[0005] Preferably, the switching assembly includes four sets of movable openings on a disc. A bearing seat is fixedly mounted on both sides of each movable opening at the upper end of the disc. A connecting rod is movably mounted inside each of the two sets of bearing seats. A first helical gear is fixedly mounted on the outer side of each of the two sets of connecting rods. A cylinder is fixedly mounted between the two sets of first helical gears. A first hydraulic cylinder is fixedly mounted inside the cylinder. A U-shaped frame is fixedly mounted at the lower end of the telescopic rod of the first hydraulic cylinder. A circular shaft is rotatably mounted on the lower side of the U-shaped frame. Rollers are fixedly mounted on the outer sides of each of the two sets of circular shafts. Slide bars are fixedly mounted on both sides of the four sets of right-angle rods. A motor base is fixedly mounted at the upper end of the disc. A drive motor is fixedly mounted at the upper end of the motor base. A second helical gear is fixedly mounted at the lower end of the drive motor's rotating shaft. A fixing ring is fixedly mounted on the outer side of the connecting cover at the upper end of the disc. A helical gear ring is movably mounted on the fixing ring.

[0006] Preferably, the wave simulation component includes a second fixed base fixedly disposed at one end of the simulation pool, a second hydraulic cylinder fixedly disposed at one end of the second fixed base, a round bar fixedly disposed at one end of the telescopic rod of the second hydraulic cylinder, two sets of bushings fixedly disposed on the inner wall of the simulation pool, a connecting shaft movably disposed inside the two sets of bushings, a push plate fixedly disposed at the upper end of the connecting shaft, and two sets of sliding sleeves fixedly disposed at one end of the push plate corresponding to the position of the round bar.

[0007] Preferably, the connecting column, connecting cover, and disc are an integral structure, and the several sets of outer sliding grooves, inner sliding grooves, and balls are arranged in a circular and uniform manner, with the outer sliding grooves, inner sliding grooves, and balls being adapted to each other.

[0008] Preferably, the balls are slidably disposed on the inner sides of the corresponding outer and inner slide grooves, and the four sets of right-angle rods and springs are arranged in a uniform circular pattern, with the springs installed in an inclined state.

[0009] Preferably, the movable opening corresponds to the upper side of the right-angle rod, and two sets of the first helical gears, cylinders, and first hydraulic cylinders are arranged inside the movable opening. The first helical gears and the helical gear ring are meshed, and the first hydraulic cylinders are in an inclined state.

[0010] Preferably, the two sets of circular shafts correspond to the upper positions of the slide bars on both sides of the right-angle rod, and the rotating shaft of the drive motor passes through the motor base and is connected to the second helical gear, which is meshed with the helical gear ring.

[0011] Preferably, the second hydraulic cylinder is installed at an angle, the telescopic rod of the second hydraulic cylinder passes through one side of the simulation pool to the inner side, the round bar is movably disposed inside the two sets of sliding sleeves, and the push plate is set at an angle.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The second hydraulic cylinder pushes the round bar to achieve telescopic movement, which in turn drives the push plate and connecting shaft to rotate along the bushing. At the same time, the round bar slides stably inside the two sets of sliding sleeves, and the swinging push plate disturbs the water inside the simulation pool, thereby simulating the working condition of facing the waves head-on during navigation. In conjunction with the front wave simulation component, it can simultaneously create a wave environment acting on the side of the simulator, and can realize independent control of waves in multiple directions, and can flexibly switch between different wave environments.

[0013] The generated wave impact simulator has a fixed column on the upper side that works with the inner slide, connecting ring and ball bearings to rotate flexibly inside the outer slide of the connecting cover. During the rotation, four sets of springs provide elastic support to four sets of right-angle rods and fixed columns. Combined with the synergistic effect of multiple wave simulation components, the simulator can compress or stretch the springs to produce elastic deformation when subjected to wave forces, achieving free swinging at multiple angles. This reproduces the natural swaying state of a ship when it is moored on the water, ensuring the realism of the swing simulation, and also buffering the instantaneous impact load of waves, reducing structural fatigue and wear.

[0014] The drive motor drives the second helical gear to rotate, causing the meshing helical gear ring to rotate inside the fixed ring. The helical gear ring synchronously drives the first helical gears around it, causing the first helical gears to drive the connecting rod to rotate along the shaft seat, adjusting the first hydraulic cylinders around it to a vertical working posture. At the same time, the rollers are attached to the surface of the slide bar. When the simulator is exposed to waves, the corresponding two sets of first hydraulic cylinders cooperate to extend and retract, pushing the slide bar and the right-angle rod, causing the simulator, the fixed column and the rotating ball to deflect and move within the connecting cover. The other two sets of first hydraulic cylinders can be linked to control the simulator to complete the lateral swing, fully simulating the bumps, vibrations and undulations of the ship during navigation, as well as realizing the switching between the two states when moored.

An inner groove 35 is provided at each position of the outer groove 33. A connecting ring 36 is fitted between the rotating ball 34 and the inner wall of the connecting cover 32. A ball bearing 37 is provided at each position of the outer groove 33 and inner groove 35 corresponding to the inner side of the connecting ring 36. A disc plate 38 is fixedly installed at the lower end of the connecting cover 32. A fixing post 39 is fixedly installed at the lower end of the rotating ball 34.

A spring 313 is fixedly connected between the disc plate 38 and the corresponding first fixing seat 312 on the right-angle rod 311.

[0020] The connecting column 31, connecting cover 32, and disc 38 are integrated into one structure. Several sets of outer sliding grooves 33, inner sliding grooves 35, and ball bearings 37 are evenly arranged in a circle. The outer sliding grooves 33 and inner sliding grooves 35 are adapted to the ball bearings 37. The ball bearings 37 are slidably set inside the corresponding outer sliding grooves 33 and inner sliding grooves 35. Four sets of right-angle rods 311 and springs 313 are evenly arranged in a circle. The springs 313 are installed in an inclined state.

[0021] The generated waves continuously impact the simulator 5. The upper side of the simulator 5 is connected by a fixed column 39, an inner slide groove 35, a connecting ring 36, and a ball bearing 37. It can rotate flexibly inside the outer slide groove 33 of the connecting cover 32. During the rotation, four sets of springs 313 provide elastic support to four sets of right-angle rods 311 and the fixed column 39. Combined with the synergistic effect of multiple sets of wave simulation components 6, when the simulator 5 is subjected to wave force, it can compress or stretch the springs 313 to produce elastic deformation, realize free swinging at multiple angles, restore the natural swaying state of a ship when it is moored on the water, ensure the realism of the swing simulation, and buffer the instantaneous impact load of the waves to reduce structural fatigue loss.

[0022] The switching assembly 4 includes four sets of movable openings 41 on the disc 38. Shaft seats 42 are fixedly installed on both sides of the movable openings 41 at the upper end of the disc 38. Connecting rods 43 are movably installed inside each of the two sets of shaft seats 42. First helical gears 44 are fixedly installed on the outer sides of each of the two sets of connecting rods 43. A cylinder 45 is fixedly installed between the two sets of first helical gears 44. A first hydraulic cylinder 46 is fixedly installed inside the cylinder 45. A U-shaped frame 47 is fixedly installed at the lower end of the telescopic rod of the first hydraulic cylinder 46. A circular shaft 48 is rotatably mounted on the lower side. Rollers 49 are fixedly mounted on the outer sides of both sets of circular shafts 48. Slide bars 410 are fixedly mounted on both sides of four sets of right-angle rods 311. A motor base 411 is fixedly mounted on the upper end of the disc 38. A drive motor 412 is fixedly mounted on the upper end of the motor base 411. A second helical gear 413 is fixedly mounted on the lower end of the rotating shaft of the drive motor 412. A fixing ring 414 is fixedly mounted on the outer side of the connecting cover 32 at the upper end of the disc 38. A helical gear ring 415 is movably mounted on the fixing ring 414.

[0023] The movable opening 41 corresponds to the upper position of the right-angle rod 311. Two sets of first helical gears 44, cylinders 45, and first hydraulic cylinders 46 are arranged inside the movable opening 41. The first helical gears 44 and helical gear rings 415 are meshed. The first hydraulic cylinders 46 are in an inclined state. Two sets of round shafts 48 correspond to the upper positions of the slide bars 410 on both sides of the right-angle rod 311. The rotating shaft of the drive motor 412 passes through the motor base 411 and is connected to the second helical gear 413. The second helical gear 413 and helical gear rings 415 are meshed.

[0024] The drive motor 412 drives the second helical gear 413 to rotate, which in turn drives the meshing helical gear ring 415 to rotate inside the fixed ring 414. The helical gear ring 415 synchronously drives the first helical gears 44 around it, which in turn drive the connecting rod 43 to rotate along the shaft seat 42. This adjusts the first hydraulic cylinders 46 around it to a vertical working position. At the same time, the roller 49 is attached to the surface of the slide bar 410. When the simulator 5 is exposed to waves, the two sets of first hydraulic cylinders 46 cooperate to extend and retract, pushing the slide bar 410 and the right-angle rod 311. This causes the simulator 5, the fixed column 39, and the rotating ball 34 to deflect and move within the connecting cover 32. The other two sets of first hydraulic cylinders 46 can be linked to control the simulator 5 to complete the lateral swing, fully simulating the bumps, vibrations, and undulating jumping postures of a ship during navigation, as well as switching between the two states when the ship is moored.

[0025] The wave simulation component 6 includes a second fixed base 61 fixedly installed at one end of the simulation pool 1. A second hydraulic cylinder 62 is fixedly installed at one end of the second fixed base 61. A round bar 63 is fixedly installed at one end of the telescopic rod of the second hydraulic cylinder 62. Two sets of bushings 64 are fixedly installed on the inner wall of the simulation pool 1. A connecting shaft 65 is movably installed inside the two sets of bushings 64. A push plate 66 is fixedly installed at the upper end of the connecting shaft 65. Two sets of sliding sleeves 67 are fixedly installed at one end of the push plate 66 corresponding to the position of the round bar 63.

[0026] The second hydraulic cylinder 62 is installed at an angle. The telescopic rod of the second hydraulic cylinder 62 passes through one side of the simulation pool 1 to the inner side. The round bar 63 is movably set inside the two sets of sliding sleeves 67. The push plate 66 is set at an angle.

[0027] The second hydraulic cylinder 62 pushes the round bar 63 to achieve telescopic movement, which in turn drives the push plate 66 and the connecting shaft 65 to rotate along the bushing 64. At the same time, the round bar 63 slides stably inside the two sets of sliding sleeves 67. The swinging push plate 66 disturbs the water inside the simulation pool 1, thereby simulating the working condition of facing the waves head-on during navigation. In conjunction with the front wave simulation component 6, it can simultaneously create a wave environment acting on the side of the simulator 5, and can realize independent control of waves in multiple directions, and can flexibly switch between different wave environments.

[0028] Working principle: During use, the second hydraulic cylinder 62 pushes the round bar 63 to achieve telescopic movement, which in turn drives the push plate 66 and the connecting shaft 65 to rotate along the bushing 64. At the same time, the round bar 63 slides stably inside the two sets of sliding sleeves 67. The swinging push plate 66 disturbs the water inside the simulation pool 1, thereby simulating the working condition of facing waves head-on during navigation. With the front wave simulation component 6, a wave environment acting on the side of the simulator 5 can be created simultaneously. Multi-directional independent wave control can be achieved, and different wave environments can be flexibly switched. In addition, the generated waves continuously impact the simulator 5. The upper side of the simulator 5 can rotate flexibly inside the outer sliding groove 33 of the connecting cover 32 through the fixed column 39, the inner sliding groove 35, the connecting ring 36 and the ball 37. During the rotation, the four sets of springs 313 provide elastic support for the four sets of right-angle rods 311 and the fixed column 39. Combined with the synergistic effect of multiple sets of wave simulation components 6, the simulator 5 can compress or stretch the springs 313 to produce elastic deformation when subjected to wave force, achieving multi-angle freedom. The oscillation reproduces the natural swaying state of a ship when it is moored on the water, ensuring the realism of the oscillation simulation and buffering the instantaneous impact load of waves, reducing structural fatigue loss. Secondly, the drive motor 412 drives the second helical gear 413 to rotate, which drives the meshing helical gear ring 415 to rotate inside the fixed ring 414. The helical gear ring 415 synchronously drives the first helical gear 44 around it, so that the first helical gear 44 drives the connecting rod 43 to rotate along the shaft seat 42, adjusting the first hydraulic cylinder 46 around it to a vertical working posture. At the same time, the roller 49 is attached to the surface of the slide bar 410. When the simulator 5 is hit by waves, the corresponding two sets of first hydraulic cylinders 46 cooperate to extend and retract, pushing the slide bar 410 and the right angle rod 311, so that the simulator 5, the fixed column 39 and the rotating ball 34 deflect and move within the connecting cover 32. The other two sets of first hydraulic cylinders 46 can be linked to control the simulator 5 to complete the lateral oscillation, fully simulating the bumping, vibration and undulating jumping posture of the ship during the sailing process, and realizing the switching between the two states when moored.

[0029] The electrical connection or control methods of the simulation pool 1, connecting component 3, first hydraulic cylinder 46, drive motor 412, simulator 5, and second hydraulic cylinder 62 in this invention are common knowledge in the field, and their working principles are well-known technologies. The appropriate model is selected according to actual use, so it will not be explained in detail.
