Description

Technical Field

[0001] The utility model relates to a ship navigation aid sail, belonging to the technical field of ship navigation aid equipment. Background Technique

[0002] A sail is a device that uses wind power to propel a ship forward and is often installed on small ships such as sailboats.

[0003] Publication number: CN220114798U, which mentions a ship navigation aid sail. When the device adjusts the direction of the sail according to the wind direction, it can quickly rotate the turntable, and then drive the worm gear to rotate through the worm, so that the mast drives the sail to rotate, effectively using the turntable and the worm gear to save labor consumption. At the same time, using the automatic locking function of the worm gear, the sail is automatically fixed without manual binding work, improving work efficiency. However, when there is a strong wind outside, it will blow tightly on the sail, causing the indirect locking between the mast, the worm and the worm gear, and then making it difficult for the staff to turn the worm, affecting subsequent use. Now there is an urgent need for a ship navigation aid sail to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a ship navigation aid sail to solve the problems put forward in the above background technique. The utility model designs an electric drive transmission sail structure, which can drive itself to adjust the angle, is not easily affected by strong winds outside, and does not require manual adjustment.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions: A ship navigation aid sail includes a first flange, a rotary limit cylinder, a gear seat and a driving bevel gear. A mast is longitudinally installed inside the first flange. The sail body is installed at the rear of the mast through bolts. The lower end of the first flange is fixed to the second flange through a plurality of bolts. The rotary limit cylinder is fixed outside the second flange. Two bearing seats are installed inside the gear seat. A driven rod is installed through the inner rings of the two bearing seats. A driven bevel gear is fixed to the outside of the driven rod. A brake motor and an electromagnetic brake are installed at the right end of the gear seat. A driving bevel gear is installed at the shaft end of the brake motor. The driving bevel gear is meshed with the driven bevel gear for transmission.

[0006] Furthermore, a threaded rod is inserted into the upper left side of the rotary limit cylinder through threads. A handwheel is installed at the upper end of the threaded rod. The lower end of the threaded rod abuts against the gear seat.

[0007] Furthermore, a fixing plate is horizontally fixed at the lower end of the gear seat.

[0008] Furthermore, the upper end of the driven rod passes through the second flange and abuts against the lower end of the mast.

[0009] Furthermore, a limiting sliding groove is formed at the upper end of the gear seat, and the lower end of the rotating limiting cylinder is slidably located in the limiting sliding groove.

[0010] Furthermore, a motor seat is installed at the lower end of the braking motor.

[0011] The beneficial effects of the present utility model: A ship-assisting sail of the present utility model. Due to the addition of the first flange, the second flange, the rotating limiting cylinder, the threaded rod, the hand wheel, the gear seat, the bearing seat, the driven bevel gear, the driven rod, the driving bevel gear, the braking motor and the electromagnetic brake in the present utility model, through our design improvement and actual use, it shows that the structure of this device is reasonable, has good practicability, designs an electric drive transmission sail structure, can drive itself for angle adjustment, is not easily affected by strong winds from the outside, and does not require manual adjustment, saving time and effort.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please refer to Figures 1 - 3, the present utility model provides a technical solution: a ship navigation sail, including a first flange 3, a rotary limit cylinder 5, a gear seat 9 and a driving bevel gear 14. A mast 2 is longitudinally installed in the first flange 3. A sail main body 1 is installed at the rear side of the mast 2 through bolts. The lower end of the first flange 3 is fixed to a second flange 4 through a plurality of bolts. The rotary limit cylinder 5 is fixed to the outer side of the second flange 4. Two bearing seats 11 are installed inside the gear seat 9. A driven rod 13 is installed through the inner rings of the two bearing seats 11. A driven bevel gear 12 is fixed to the outside of the driven rod 13. A braking motor 15 and an electromagnetic brake 16 are installed at the right end of the gear seat 9. A driving bevel gear 14 is installed at the shaft end of the braking motor 15. The driving bevel gear 14 is in meshing transmission with the driven bevel gear 12. This design solves the problem that when there is a strong wind outside the original device, it will blow tightly on the sail, causing the indirect locking between the mast, the worm and the worm gear, and then making it impossible for the staff to turn the worm, affecting subsequent use.

[0019] As the first embodiment of the present utility model: a threaded rod 6 is inserted through the left side of the upper end of the rotary limit cylinder 5. A handwheel 7 is installed at the upper end of the threaded rod 6. The lower end of the threaded rod 6 abuts against the gear seat 9. A limit chute 8 is opened at the upper end of the gear seat 9. The lower end of the rotary limit cylinder 5 is slidably located in the limit chute 8. By adding that the lower end of the threaded rod 6 abuts against the gear seat 9, the rotary limit cylinder 5 can be prevented from rotating by itself in the limit chute 8. A fixing plate 10 is horizontally fixed at the lower end of the gear seat 9. The upper end of the driven rod 13 passes through the second flange 4 and abuts against the lower end of the mast 2. When the driven rod 13 is driven to rotate, the first flange 3 and the mast 2 can be driven to rotate through the second flange 4. A motor seat 17 is installed at the lower end of the braking motor 15. By adding the motor seat 17, it is convenient to support the braking motor 15.

[0020] As the second embodiment of the present utility model: when the angle of the sail main body 1 needs to be adjusted (note: the circuits and electronic components involved in the present utility model are all prior arts and can be fully realized by those skilled in the art without further elaboration), start the braking motor 15 and the electromagnetic brake 16. The braking motor 15 drives the driving bevel gear 14 to rotate, and then the driven bevel gear 12 rotates meshingly. Then the driven rod 13 can be driven to rotate. When the driven rod 13 is driven to rotate, the first flange 3 and the mast 2 can be driven to rotate through the second flange 4 (during this process, the rotary limit cylinder 5 rotates in the limit chute 8). Then the angle of the sail main body 1 can be adjusted. After the angle of the sail main body 1 is adjusted, turn off the braking motor 15 and the electromagnetic brake 16. The electromagnetic brake 16 holds the shaft end of the braking motor 15 to prevent it from rotating by itself. Then turn the handwheel 7 so that the lower end of the threaded rod 6 abuts against the gear seat 9.

[0021] The foregoing has shown and described the basic principles, main features and advantages of the present invention. For a person skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and without departing from the spirit or basic features of the present invention, the present invention can be implemented in other specific forms.
