Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to a retractable sector-shaped marine anti-rolling device. Background Art

[0002] When a ship sails in waves, currents, and winds, it is severely affected by the ship's rolling, which reduces the safety of ship navigation, the comfort of crew members and passengers. In severe cases, it may cause seasickness among crew members, and is more likely to reduce the seaworthiness of the ship. Moreover, under the impact of waves, the ship's rolling may accelerate the hull damage and cause abnormal operation of instruments and the like. In order to reduce the rolling state of the ship, anti-rolling fins, anti-rolling water tanks, bilge keels and other anti-rolling devices are widely used in the current technical field. Among them, the anti-rolling fins have the best anti-rolling effect, but there are problems such as the anti-rolling fins being too large in volume and occupying space, or too small in volume and having poor anti-rolling effect. At the same time, the power of the current anti-rolling devices purely comes from external power, which requires energy dissipation and the energy utilization cannot achieve secondary utilization. Most of the current anti-rolling fins are used for medium and high-speed ships, and are less used for low-speed ships, with a relatively high cost. Summary of the Invention

[0003] The purpose of the present invention is to overcome the defects existing in the above-mentioned prior art, and provide a retractable sector-shaped marine anti-rolling device, which can perform the scaling of the sector-shaped wing, so as to balance the anti-rolling effect and the occupied volume; at the same time, it also has a mechanical energy recovery function, increasing the energy utilization rate.

[0004] The purpose of the present invention can be achieved by the following technical solutions:

[0005] A retractable sector-shaped marine anti-rolling device, comprising:

[0006] A receiving cavity, which is arranged on one side of the bottom of the ship's hull and has an opening, and the receiving cavity includes a first cavity and a second cavity that are communicated with each other;

[0007] An anti-rolling body sector-shaped wing, which is arranged in the second cavity;

[0008] A motor reduction module, which is arranged in the first cavity, and the output shaft of the motor reduction module is connected to the anti-rolling body sector-shaped wing;

[0009] An anti-rolling rotation module, which is arranged in the first cavity and is used to connect and drive the whole motor reduction module to rotate, and the anti-rolling body sector-shaped wing rotates with the motor reduction module and leaves the second cavity from the opening.

[0010] In another preferred embodiment, the motor reduction module includes a rotating box body, an output shaft, a driving motor and a reducer arranged in the rotating box body, and the driving motor is connected to the output shaft through the reducer.

[0011] In another preferred embodiment, the motor reduction module includes a micro generator, the input end of the micro generator is connected to the output shaft, and the output end is connected to the drive motor.

[0012] In another preferred embodiment, the anti-rolling rotation module includes a support base, a hydraulic rod, a rotating disc and a rotating shaft. The support base is fixed in the first cavity. The rotating shaft is rotatably passed through the support base and then fixedly connected to the motor reduction module. One end of the hydraulic rod is fixedly connected to the support base, and the other end is connected to the rotating shaft through the rotating disc.

[0013] In another preferred embodiment, a limiting member is provided on the support base. The rotating disc is a cam structure. When the rotating disc rotates a certain angle driven by the hydraulic rod, the protrusion of the cam structure contacts the limiting member to prevent the rotating disc from continuing to rotate.

[0014] In another preferred embodiment, an angle sensor is provided on the rotating shaft.

[0015] In another preferred embodiment, ailerons are provided on the anti-rolling body fan wing. When the anti-rolling body fan wing is located in the first cavity, the ailerons are exposed from the opening.

[0016] In another preferred embodiment, the anti-rolling body fan wing and the ailerons are connected by a micro motor, and the ailerons can rotate vertically relative to the anti-rolling body fan wing.

[0017] In another preferred embodiment, the aileron is a right-angled sector, and one right-angled side of the aileron fits against the straight side of the anti-rolling body fan wing.

[0018] In another preferred embodiment, both the top surface and the bottom surface of the anti-rolling body fan wing have a wavy surface structure.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention designs a retractable anti-rolling body fan wing. When needed, the anti-rolling body fan wing is released to increase the water pressure stress area, effectively reducing the rolling of the hull and improving the stability of the ship; when not in use, the anti-rolling body fan wing is retracted to reduce the water flow resistance, taking into account both the anti-rolling effect and the occupied volume. At the same time, by adjusting the rotation angle of the anti-rolling body fan wing, it can adapt to various speeds and sailing environments, with a wide range of applications. For example, when the anti-rolling body fan wing is rotated to a fixed 90 degrees with the horizontal plane, it can be used as a ship brake.

[0021] 2. A micro generator is added to the motor reduction module, and the mechanical energy generated when the anti-rolling body rotates is collected by the micro generator for secondary utilization, increasing the energy utilization rate.

[0022] 3. An angle sensor and an angle brake are provided on the rotating shaft, which can effectively and accurately control the rotation angle, that is, the extension angle of the fan-shaped wing of the anti-rolling body, better adapt to the ship's navigation, and improve the anti-rolling effect.

[0023] 4. Ailerons are provided on the fan-shaped wing of the anti-rolling body. When the body of the fan-shaped wing of the anti-rolling body contracts, the ailerons can directly serve as the anti-rolling body to achieve the anti-rolling effect; when the fan-shaped wing of the anti-rolling body extends, the ailerons increase the area of the anti-rolling body.

[0024] 5. Both the top surface and the bottom surface of the fan-shaped wing of the anti-rolling body have a wavy surface structure, which reduces the water flow resistance while achieving anti-rolling. Brief Description of the Drawings

Detailed Description of the Invention

[0031] The present invention will be described in detail below with reference to the drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operation processes are given, but the protection scope of the present invention is not limited to the following embodiments.

[0032] As Figure 1As shown in the figure, this embodiment provides a retractable fan-shaped marine anti-rolling device, which includes a receiving cavity, an anti-rolling body fan wing 1, a motor reduction module 2, and an anti-rolling rotation module 3. Among them: The receiving cavity is arranged on one side of the bottom of the hull and has an opening. Inside the receiving cavity, there is a first cavity and a second cavity that communicate with each other. The anti-rolling body fan wing 1 is arranged in the second cavity. The motor reduction module 2 is arranged in the first cavity, and the output shaft 22 of the motor reduction module 2 is connected to the anti-rolling body fan wing 1. The anti-rolling rotation module 3 is also arranged in the first cavity, and is used to connect and drive the entire motor reduction module 2 to rotate. The anti-rolling body fan wing 1 can rotate horizontally following the motor reduction module 2 and leave the second cavity from the opening.

[0033] The working process of this embodiment is as follows: The entire retractable fan-shaped marine anti-rolling device is arranged at the bottom (side) of the hull. The power is transmitted to the motor reduction module 2 through the anti-rolling rotation module 3, and the motor reduction module 2 is horizontally rotated by any angle within 90 degrees and released from the inside of the receiving cavity. The internal structure of the motor reduction module 2 provides rotational power to make the anti-rolling body fan wing 1 rotate by a certain angle to reduce the roll of the ship.

[0034] As Figure 2 shown, specifically, the anti-rolling rotation module 3 includes a support base 31, a hydraulic rod 32, a rotating disk 33, and a rotating shaft 34. The support base 31 is fixed inside the first cavity. The rotating shaft 34 can rotatably pass through the support base 31 and is fixedly connected to the motor reduction module 2 located below. One end of the hydraulic rod 32 is fixedly hinged to the support base 31, and the other end is connected to the rotating shaft 34 through the rotating disk 33. More specifically, the hydraulic rod 32 is composed of a hydraulic cylinder sleeve 321, a hydraulic cylinder slide rod 322, and a hydraulic cylinder base 323. By the telescopic movement of the hydraulic cylinder slide rod 322 in the hydraulic rod 32, the rotating disk 33 and the rotating shaft 34 are driven to rotate, and the anti-rolling body fan wing 1 is released from the hull.

[0035] Continuing as Figure 2 shown, further, a limiting member 35 is provided on the support base 31. The limiting member 35 can adopt a structure such as a baffle, and the rotating disk 33 adopts a cam structure. When the rotating disk 33 rotates by a certain angle driven by the hydraulic rod 32, the protrusion of the cam structure contacts the limiting member 35, preventing and locking the rotating disk 33 from continuing to rotate. This structure is used to limit the maximum extension angle of the anti-rolling body fan wing 1 and plays a protective role. The rotating shaft 34 and the support base 31 are connected through a bearing 38 to achieve relative rotation.

[0036] Continuing as Figure 2As shown in the figure, further, an angle sensor 36 and an angle brake 37 are installed on the rotating shaft 34. The angle sensor 36 and the angle brake 37 can measure the rotation angles of the anti-rolling body sector wing 1 and the motor reduction module 2, and the angle brake performs angle adjustment. Thus, the rotation angle can be effectively and precisely controlled, that is, the extension angle of the anti-rolling body sector wing 1, so as to better adapt to ship navigation and improve the anti-rolling effect.

[0037] As Figure 3 shown in the figure, specifically, the motor reduction module 2 includes a rotating box body 21, an output shaft 22, a driving motor 23 and a reducer 24. Among them, the driving motor 23 is a reversible motor, and the reducer 24 is a reversing reducer 24. The rotating box body 21 is fixedly connected to the retracting shaft sleeve 26 by bolts and rotates fixedly. The retracting shaft sleeve 26 is connected to the rotating shaft 34 through a spline 25. The rotating shaft 34 drives the retracting shaft sleeve 26 to rotate, thereby driving the rotating box body 21 to rotate. The driving motor 23 and the reducer 24 are arranged in the rotating box body 21. The driving motor 23 is connected to the reducer 24 through a coupling 27, and the reducer 24 is connected to the output shaft 22 through an internal reversing gear set. Thus, the driving motor 23 can drive the anti-rolling body sector wing 1 to rotate clockwise and counterclockwise around the output shaft 22 through the reducer 24, so as to achieve the anti-rolling effect.

[0038] Continuing as Figure 3 shown in the figure, further, the motor reduction module may further include a micro generator 28. The input end of the micro generator 28 is connected to the output shaft 22, and the output end is connected to the driving motor 23. The micro generator 28 collects and generates mechanical energy through the rotation of the anti-rolling body sector wing 1, increasing the energy utilization rate.

[0039] As Figure 4 shown in the figure, in another preferred embodiment, a flap 11 is provided on the anti-rolling body sector wing 1. The flap 11 is a right-angled sector, and one right-angled side of the flap 11 fits the straight side of the anti-rolling body sector wing 1. The anti-rolling body sector wing 1 and the flap 11 are connected by a micro motor, and the flap 11 can rotate vertically relative to the anti-rolling body sector wing 1, as shown by the rotation direction in the figure. Thus, when the anti-rolling body sector wing 1 contracts into the first cavity, the flap 11 can be exposed from the opening of the second cavity and rotate under the action of the micro motor to form a small-volume anti-rolling body. When the anti-rolling body sector wing 1 extends as a whole, the flap 11 can increase the area of the original anti-rolling body.

[0040] Further, both the top surface and the bottom surface of the anti-rolling body sector wing 1 have a wavy surface structure, which reduces the water flow resistance while achieving anti-rolling.

[0041] Furthermore, the second cavity of the accommodation cavity has a relatively large depth. When the fan-shaped wing 1 of the anti-rolling body rotates 90 degrees by itself under the action of the micro motor first and then folds up, the aileron 11 can also be completely accommodated in the accommodation cavity, playing a role of hiding.

[0042] In summary, this embodiment adopts the combined method of the fan-shaped wing and the aileron, increasing the area of the anti-rolling body, and adopting the wavy surface structure to reduce the water flow resistance. This retractable fan-shaped marine anti-rolling device also uses a generator to collect the mechanical energy when the anti-rolling body rotates for secondary utilization, increasing the energy utilization rate. The anti-rolling device can adjust the angle and the rotation speed of the fan-shaped wing and the aileron when working according to environmental requirements, and is applicable to high, medium and low speed ships.
