Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to a novel bow mast type energy-saving rotating wind tube. Background Art

[0002] Ship navigation consumes a large amount of fossil energy. As the International Maritime Organization has increasingly stringent requirements for environmental protection, many ships have adopted the method of adding energy-saving devices to reduce their energy consumption levels.

[0003] The rotating wind tube is an energy-saving device that utilizes wind energy through the Magnus effect. It is cylindrical in shape, relatively tall, and stands on the deck of a ship. Currently, it has been put into practical use on many ships. The rotating wind tube utilizes the Magnus effect in fluid mechanics. The Magnus effect describes the force exerted on an object rotating in a fluid (such as air), and explains the relationship between the velocity and pressure of a fluid (such as air). When the fluid velocity is fast, the pressure decreases, and when the fluid velocity is slow, the pressure increases. The air flows from left to right, and the cylinder rotates clockwise. The airflow above the cylinder is fast and the pressure is low, while the airflow below the cylinder is slow and the pressure is high, which causes the cylinder to be subjected to an upward thrust.

[0004] However, the current rotary wind tube can only be applied to larger ships. For smaller ships, the application has great limitations. The main reasons are: 1. The rotary wind tube needs to occupy part of the deck area. Small ships are often compactly arranged and have a small available deck area; 2. The rotary wind tube will cause a large line of sight obstruction. Ship navigation regulations have certain requirements for the ship's driving line of sight, such as a single blind area within 10 degrees on the left and right sides of the ship's center in front of the ship's center shall not exceed 5 degrees, a single blind area in other areas in front shall not exceed 10 degrees, the total blind area shall not exceed 20 degrees, and the angle between the blind areas shall be at least 5 degrees. When the ship is small, the distance between the rotary wind tube and the line of sight point is relatively small, so the line of sight blind area is also large. In addition, the blind area caused by the ship's own equipment (such as bow mast, crane column), etc., has caused certain limitations on the application of rotary wind tubes on smaller ships.

[0005] Ship navigation usually needs to comply with the International Regulations for Preventing Collisions at Sea or the Regulations for Preventing Collisions in Inland Waters, as well as some signal identification requirements for specific navigation areas. The basic configuration of ship navigation signal lights is the forward mast light, port light (red), starboard light (green), aft mast light and stern light from the bow to the stern. These lights have not only visible angle requirements, but also visible distance and height requirements. For example, the height of the forward mast light must be at least 12m higher than the main deck of the ship. Therefore, in order to meet the signal light requirements, ships are usually designed with a forward mast for arranging the forward mast light and other signal equipment, such as the bow anchor light, out-of-control light, whistle, etc.

[0006] The prior art has the following disadvantages:

[0007] 1. The application of rotary wind tubes on smaller ships has certain limitations;

[0008] 2. The rotating wind tube brings more blind spots, affecting the ship's driving vision;

[0009] 3. Rotating motors and other equipment need to be installed under the rotating wind tube, which requires a special area and space, occupying a larger deck area. Summary of the invention

[0010] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide a new type of bow mast type energy-saving rotary wind tube.

[0011] The present invention solves the above technical problems through the following technical solutions:

[0013] Furthermore, the rack is fixed to the inner wall of the wind cylinder body, and the rack is distributed circumferentially along the inner wall of the wind cylinder body.

[0014] Furthermore, a notch is provided at the lower part of the signal light mast; and the driving gear is arranged in the notch.

[0015] Furthermore, the driving motor is arranged below the forecastle deck; and the rotating shaft of the driving motor passes through the forecastle deck.

[0016] Furthermore, bearings are arranged between the upper part of the wind cylinder body and the signal light mast, between the middle part of the wind cylinder body and the signal light mast, and between the lower part of the wind cylinder body and the signal light mast.

[0026] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0027] like Figure 1 and Figure 2 As shown, a new type of fore mast type energy-saving rotary wind tube includes a wind tube body 10; it also includes a signal light mast body 20 and a drive motor 30. The signal light mast body 20 is fixed on the fore deck 21, and the wind tube body 10 is sleeved on the signal light mast body 20. The signal light mast body 20 is cylindrical.

[0028] A bearing 12 is provided between the signal light mast 20 and the wind cylinder body 10. A bearing 12 is provided between the upper part of the wind cylinder body 10 and the signal light mast 20, between the middle part of the wind cylinder body 10 and the signal light mast 20, and between the lower part of the wind cylinder body 10 and the signal light mast 20.

[0029] The bearing between the wind cylinder body and the signal light mast body can support the rotation of the wind cylinder body and prevent the wind cylinder body from falling off the signal light mast body.

[0030] The signal light mast can be made of steel, and the wind tube body can be made of lightweight and high-strength material.

[0031] A rack 11 is fixedly arranged on the air cylinder body 10. The rack 11 is fixedly arranged on the inner wall of the air cylinder body 10, and the rack 11 is distributed circumferentially along the inner wall of the air cylinder body.

[0032] A driving gear 31 is fixedly connected to the rotating shaft of the driving motor 30 , and the driving gear 31 is meshed with the rack 11 .

[0033] When the driving motor is running, the driving gear rotates along with the rotating shaft of the driving motor, and the driving gear drives the rack to make the wind cylinder body rotate outside the signal light mast body.

[0034] A notch 22 is provided at the lower portion of the signal light mast 20 ; a driving gear 31 is disposed in the notch 22 .

[0035] The driving motor 30 is arranged below the forecastle deck 21; the rotating shaft of the driving motor 30 is passed through the forecastle deck 21. The driving motor is arranged in the storage room space below the forecastle deck of the ship, and no additional deck space area is required.

[0036] A top platform 23 is fixedly provided on the top of the signal light mast 20 .

[0037] An inspection ladder 24 is provided in the inner cavity of the signal light mast 20; an inspection hatch 25 is provided on the top platform 23; an inspection hole 26 is opened on the forecastle deck 21, and the inspection hole is connected to the inner cavity of the signal light mast.

[0038] The inspection hole 26 is provided in the area enclosed by the signal light mast 20 on the forecastle deck.

[0041] The new type of fore mast type energy-saving rotating wind tube of the present invention is arranged on the forecastle deck, which can reduce the influence of the wind tube on the sight line of the cab. Figure 3 As shown, when looking from the navigation cabin 41 to the bow, the blind area 40 of the fore mast is very small. The present invention can greatly reduce the influence of the wind tunnel on the navigation cabin.

[0042] The main structure of the new bow mast type energy-saving rotating wind tube consists of a signal light mast body, a wind tube body, a drive motor, a top platform, etc. The signal light, floodlight, whistle and other components on the top platform can be used when the ship is sailing. A maintenance ladder is set in the signal light mast body, which, together with the inspection hole on the bow deck and the inspection hatch on the top platform, allows personnel to enter through the inspection hole and reach the top platform for maintenance through the maintenance ladder and the inspection hatch. The wind tube body can rotate freely when the drive motor is running, and the rotation of the wind tube body provides power for the ship to move forward, thereby achieving energy-saving effects.
