Description

Technical Field

[0001] The present invention is applied to the field of ships, and particularly relates to a marine adjustable throttling device. Background Art

[0002] With the rapid development of the shipbuilding industry, ships are gradually moving towards the path of being large-sized and fast. High-speed ships are inevitably affected by water flow resistance during high-speed navigation, which may cause problems such as hull swaying and longitudinal inclination, affecting the work requirements of crew members and the riding experience of passengers. If a marine adjustable throttling device with a simple structure, capable of reducing the navigation resistance of ships and improving the navigation stability of ships can be designed, the above problems can be well solved. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a marine adjustable throttling device with a simple structure, capable of reducing the navigation resistance of ships and improving the navigation stability of ships.

[0004] The technical solution adopted by the present invention is as follows: The present invention includes a throttling plate, a wave suppressing plate, an adjustment module, and several connecting plates. The adjustment module includes an MCU controller, a displacement sensor, a flow velocity sensor, and a first hydraulic cylinder. The first hydraulic cylinder is vertically arranged on the stern seal plate of the hull and is in transmission connection with the connecting plate. The wave suppressing plate is slidably fitted on the stern seal plate through several connecting plates. The throttling plate is arranged on the wave suppressing plate. The flow velocity sensor is arranged on the bottom plate of the hull. The displacement sensor is arranged on the throttling plate. The flow velocity sensor is in signal connection with the first hydraulic cylinder through the MCU controller. The displacement sensor is in signal connection with the MCU controller.

[0005] Further, the adjustment module further includes an angle sensor and a second hydraulic cylinder. The throttling plate is hinged on the wave suppressing plate. The angle sensor is arranged on the throttling plate. The second hydraulic cylinder is horizontally arranged on the connecting plate and is in transmission connection with the throttling plate. The flow velocity sensor is in signal connection with the second hydraulic cylinder through the MCU controller. The angle sensor is in signal connection with the MCU controller.

[0006] Further, stern fins are arranged at both the left and right ends of the wave suppressing plate.

[0007] Further, both the throttling plate and the wave suppressing plate are made of high-strength aluminum plates.

[0008] The beneficial effects of the present invention are as follows: The intercepting plate changes the force condition at the stern of the ship by changing the angle with the wave-suppressing plate or the length extending out of the bottom of the ship, thereby affecting the stability of the ship when sailing in waves. When the water flow near the lower surface of the hull is blocked by the intercepting plate, vortices corresponding to the angle and telescopic length of the intercepting plate appear at the intersection of the intercepting plate and the bottom of the ship, causing the fluid motion in front of the intercepting plate to bend and bypass the vortices. At this time, the flow velocity of the fluid decreases. With the change of the flow velocity, the fluid pressure in front of the intercepting plate will increase sharply, thereby generating an upward fluid acting force at the stern of the ship, causing the trim of the ship to change.

[0009] Therefore, when the ship has trim, the flow velocity sensor senses the flow velocity at the bottom of the ship and then transmits the flow velocity data to the MCU controller. The MCU controller calculates the trim angle of the ship at this time by combining the weight of the ship and the flow velocity, and then calculates the required angle and extending length of the intercepting plate using this trim angle. Finally, the MCU controller drives the first hydraulic cylinder and the second hydraulic cylinder to drive the intercepting plate to move and rotate respectively, thereby adjusting the extending length of the intercepting plate and the angle with the wave-suppressing plate, changing the trim angle of the ship until the ship reaches balance, thereby reducing the ship's sailing resistance and increasing the sailing speed. Subsequently, the displacement sensor and the angle sensor will respectively transmit the moving value and rotation angle value of the intercepting plate to the MCU controller for collection and verification to ensure the stability of the ship's sailing.

[0013] Such as Figures 1 to 3As shown in the figure, in this embodiment, the present invention includes a cut-off plate 1, a wave-suppressing plate 2, an adjustment module, and several connecting plates 3. The adjustment module includes an MCU controller 4, a displacement sensor 5, a flow velocity sensor 6, and a first hydraulic cylinder 7. The first hydraulic cylinder 7 is vertically arranged on the stern seal plate 8 of the hull and is in transmission connection with the connecting plate 3. The wave-suppressing plate 2 is slidably fitted on the stern seal plate 8 through several connecting plates 3. The cut-off plate 1 is arranged on the wave-suppressing plate 2. The flow velocity sensor 6 is arranged on the bottom plate 9 of the hull. The displacement sensor 5 is arranged on the cut-off plate 1. The flow velocity sensor 6 is in signal connection with the first hydraulic cylinder 7 through the MCU controller 4. The displacement sensor 5 is in signal connection with the MCU controller 4.

[0014] In this embodiment, the adjustment module further includes an angle sensor 10 and a second hydraulic cylinder 11. The cut-off plate 1 is hinged on the wave-suppressing plate 2. The angle sensor 10 is arranged on the cut-off plate 1. The second hydraulic cylinder 11 is horizontally arranged on the connecting plate 3 and is in transmission connection with the cut-off plate 1. The flow velocity sensor 6 is in signal connection with the second hydraulic cylinder 11 through the MCU controller 4. The angle sensor 10 is in signal connection with the MCU controller 4.

[0015] In this embodiment, stern fins are arranged at both the left and right ends of the wave-suppressing plate 2.

[0016] In this embodiment, both the cut-off plate 1 and the wave-suppressing plate 2 are made of high-strength aluminum plates.

[0017] In this embodiment, the working principle of the present invention is as follows:

[0018] The cut-off plate changes the force condition at the stern of the ship by changing the angle with the wave-suppressing plate or changing the length extending out of the bottom of the ship, thereby affecting the stability of the ship when sailing in waves. When the water flow near the lower surface of the hull is blocked by the cut-off plate, vortices corresponding to the angle and telescopic length of the cut-off plate appear at the intersection of the cut-off plate and the bottom of the ship, causing the fluid motion in front of the cut-off plate to bend and bypass the vortices. At this time, the flow velocity of the fluid decreases. With the change of the flow velocity, the fluid pressure in front of the cut-off plate will increase sharply, thereby generating an upward fluid acting force at the stern of the ship, causing the longitudinal inclination of the ship to change.

[0019] When the ship has a trim, the flow velocity sensor 6 senses the flow velocity at the bottom of the ship, and then transmits the flow velocity data to the MCU controller 4. The MCU controller 4 calculates the trim angle of the ship at this time by combining the weight of the ship and the flow velocity, and then calculates the required intercepting plate angle and extension length using this trim angle. Finally, the MCU controller 4 drives the first hydraulic cylinder 7 and the second hydraulic cylinder 11 to drive the intercepting plate 1 to move and rotate respectively, so as to adjust the extension length of the intercepting plate 1 and the angle between the intercepting plate 1 and the wave suppressing plate 2, change the trim angle of the ship until the ship reaches balance, thereby reducing the ship's navigation resistance and increasing the navigation speed. Subsequently, the displacement sensor 5 and the angle sensor 10 will respectively transmit the moving value and the rotation angle value of the intercepting plate to the MCU controller for collection and verification to ensure the stability of the ship's navigation.

[0020] The influence of the extension length of the intercepting plate from the bottom of the ship: (1) When the extension length from the bottom of the ship is the same, the faster the ship's speed, the greater the upward force generated at the stern of the ship's hull, and the greater the trim of the hull, and vice versa; (2) When the ship's speed is constant, the longer the extension length of the intercepting plate from the bottom of the ship, the greater the upward force generated at the stern of the ship's hull, and the greater the trim of the hull, and vice versa.
