Description

Technical Field

[0001] This utility model relates to the field of maritime training technology, and in particular to a seafarer anti-sickness training device. Background Technology

[0002] Ship rolling refers to the periodic oscillating motion of a ship around its equilibrium position under the influence of wind and waves. Ship rolling includes roll, pitch, bow, sway, heave, and vertical sway, with roll, pitch, and heave having the greatest impact. Sway is a back-and-forth motion along the ship's longitudinal axis, roll is a back-and-forth motion around the ship's longitudinal axis, and heave is a back-and-forth motion along the ship's vertical axis. Ship rolling can cause fatigue and seasickness, posing a significant threat to navigational safety and the lives of crew members. Therefore, it is essential to conduct targeted adaptive training for crew members to improve their resistance to seasickness and reduce the physical and mental harm caused by ship rolling. Currently, most seasickness prevention training for crew members uses simple wave bridges or rotating windmills, which differ significantly from the actual movement of a ship at sea and fail to achieve the intended purpose of seasickness prevention training. Summary of the Invention

The lateral rocking mechanism 150 is provided between the support frame 130 and the body 111. The lateral rocking mechanism 150 includes a rack 151, a gear 152 and a lateral rocking motor (not shown in the figure). The two ends of the rack 151 are fixedly connected to the two sides of the support leg 131 respectively. The rack 151 is arc-shaped. The gear 152 is rotatably connected to the lower part of the body 111. The rack 151 and the gear 152 mesh. The lateral rocking motor is fixedly installed at the lower part of the body 111. The gear 152 is coaxially fixed with the drive shaft of the lateral rocking motor. The gear 152 rotates under the drive of the lateral rocking motor, thereby causing the body 111 to swing laterally (i.e., lateral rocking).

[0022] The swing frame 120 is rotatably connected to the frame 110. Two swing frames 120 are arranged in parallel. Each swing frame 120 includes a first swing rod 121, a second swing rod 122, and a third swing rod 123. The upper end of the first swing rod 121 is rotatably connected to the first connecting member 112. The upper end of the second swing rod 122 is rotatably connected to the second connecting member 113. The two ends of the third swing rod 123 are respectively rotatably connected to the lower ends of the first swing rod 121 and the lower ends of the second swing rod 122.

The swing mechanism 160 includes a swing motor 161, a first sprocket 162, a second sprocket 163, and a chain 164. The swing motor 161 is installed at the upper end of the body 111, and the swing motor 161... Located between the first connecting member 112 and the second connecting member 113, a first sprocket 162 is sleeved on the first connecting member 112, and a second sprocket 163 is sleeved on the second connecting member 113. The two ends of a chain 164 are respectively fixedly connected to two cabins 170. A drive sprocket 165 is coaxially fixed on the drive shaft of the swing motor 161. The chain 164 passes over the upper ends of the first sprocket 162 and the second sprocket 163 and meshes with the first sprocket 162, the second sprocket 163, and the drive sprocket 165. The cabins 170 move up and down under the drive of the swing mechanism 160. A control box 115 is also provided on the frame 110. The oscillation mechanism 140, the roll mechanism 150, and the swing mechanism 160 operate under the action of the control box 115. The control box 115 controls the hydraulic cylinder or pneumatic cylinder 141 in the swaying mechanism 140, the swaying motor in the roll mechanism 150, and the heave motor 161 in the swaying mechanism 160 using existing technology.

[0024] In the above embodiments, the swing amplitude and swing speed of the swing frame 120 can be controlled by controlling the movement amplitude and speed of the piston in the hydraulic cylinder or air cylinder 141. This control method is achieved by controlling the hydraulic or air pressure supplied to the hydraulic cylinder or air cylinder 141, which is prior art and will not be described in detail.

[0025] In addition, a video screen can be installed in the cockpit 170 as needed to play corresponding videos and sound effects based on the swaying of the cockpit 170. A monitoring and management system can also be installed in the cockpit 170 to monitor the crew's reactions under various swaying conditions. The cockpit 170 can also be equipped with a seat that can rotate 90 degrees left and right. This seat is readily available for purchase. When the seat is rotated 90 degrees, the original swaying, rolling, and heeling sensations are replaced by pitching, rolling, and bowing motions.

[0026] The anti-nausea training device can also be equipped with two motion control systems. One system is installed inside the cabin 170, allowing the crew to independently adjust the training speed, amplitude, and time of various motion modes. The other system is installed on the outside of the training device, allowing external personnel to control the training intensity of the crew. The specific control method of the motion control system is implemented using existing technology.
