Description

A paddle wheel propeller for ships

technical field

The utility model relates to the technical field of marine propulsion.

Background technique

The paddle wheel propeller is a kind of propulsion tool for ships. It is a marine propeller that partially enters the water. It is installed on both sides or the tail of the ship. Water is used to propel the ship forward, and because most of it is exposed above the water surface, it is called "paddle wheel". Paddle wheel propellers are only suitable for domestic ships with large thrust, shallow draft, low speed and no large surge, so they are gradually replaced by propellers. However, due to different purposes, with the development of ship technology, various special ships appear, such as park sightseeing ships, inland river cruise ships, etc. Using propeller propellers on water surfaces with shallow drafts and low speeds pollutes the environment and wastes energy. In the prior art, fixed paddle wheels are mostly used on low-speed boats powered by batteries. The fixed paddles are also called water-repellent boards. Most of the energy is lost, so its surface area is often made very large, and the depth of entry into the water is generally no more than 1/2 of the radius of the paddle wheel. On a low-speed ship powered by batteries, if the water-repelling plate of the movable paddle wheel is used, the surface area of the paddle wheel can be reduced, and the water-repelling plate maintains a vertical state in the water to repel water, which can reduce the propulsion resistance of the hull and save the power of the hull.

Utility model content

The technical problem to be solved by the utility model is to provide a marine paddle wheel propeller, so that when the water-repelling plate revolves around the main shaft, the cross-section of the water-repelling plate is always kept vertical, and the water-repelling plate is always in the position of obtaining a large forward thrust in the water. The angle of the water is reduced, thereby reducing the ineffective work of the pressurized water as much as possible, and at the same time, the water outlet resistance is also reduced, so that the propulsion power consumption of the hull is reduced, which is beneficial to environmental protection.

In order to solve the problems of the technologies described above, the technical solution adopted by the utility model is:

A marine paddle wheel propeller, including a central gear, a main shaft, a driven gear, an upper support plate, a lower support plate, a rotating shaft and a water-repelling plate; the central gear is fixed on one side of the ship’s side, and one end of the main shaft passes through the ship’s side and the central gear and are vertically fixedly connected with the middle part of the upper support plate and the middle part of the lower support plate, and the main shaft is in dynamic cooperation with the central gear; The upper ends are fitted with the upper supporting plate respectively, the lower ends of the left and right rotating shafts respectively pass through the lower supporting plate and are fixedly installed with driven gears, and the driven gears are all meshed with the central gear; The left water-repelling plate connected to the left rotating shaft and the right water-repelling plate fixedly connected to the right rotating shaft, both the left water-repelling plate and the right water-repelling plate are located between the upper support plate and the lower support plate; the other end of the main shaft Connect with shipboard power machine.

In the aforementioned marine paddle wheel propeller, the section of the water-repelling plate is kept vertical and installed on the rotating shaft.

In the aforementioned marine paddle wheel propeller, an intermediary gear meshed between the central gear and the driven gear is provided, and the intermediary gear is installed on the lower support plate through the central shaft, and the number of intermediary gears on both sides of the central gear is equal.

In the above-mentioned marine paddle wheel propeller, the central gear is provided with a conjoined gear flange, and the gear flange is fastened on the side of the ship by bolts; the upper support plate and the lower support plate are respectively provided with a support plate Flanges, the flanges of the support plate are all fixedly connected with the main shaft.

The marine paddle wheel propeller of the utility model adopts a gear linkage mechanism, so that the rotation angle of the water-repelling plate is equal to the revolution angle of the upper support plate and the lower support plate, and the direction is opposite. In the water, water is always diverted to the rear of the hull (or in other words, the component force of diverting water to the rear of the hull is maximized), so that the hull can obtain greater thrust and reduce the water outlet resistance of the water-repellent plate. The thruster has a simple structure, is convenient to use and maintain, can save energy and power, and is beneficial to environmental protection.

Detailed ways

As shown in Figure 1, the central gear 11 of the utility model is connected with the gear flange 10, and the gear flange 10 is fixed on the ship's side 8, and the central gear 11 is meshed with the intermediate gear 13 and the driven gear 7 on both sides of the utility model. Gear linkage.

As shown in Figures 2 and 3, the ship-borne power machine 15 drives the main shaft 9 to rotate in the central gear 11, and drives the frame consisting of the upper support plate 2 and the lower support plate 12 to rotate. Since the section of the water-repelling plate remains vertical, it is installed on the On the rotating shaft, so the section of the water-repelling plate on the two rotating shafts (the short-axis section of the water-repelling plate, that is, the section of the water-repelling plate shown in Fig. 2 ) can always be kept vertical. The reason for adopting such a design is: if the height of the main axis 9 is located on the water surface, the main axis 9 is the center of the plane in the Cartesian coordinate system where the water-repellent plate revolves once, and the water-repellent plate enters the water in the third quadrant and the fourth quadrant. To obtain power for the hull, since the two water-repellent plates are always kept vertical, the water-repel action is always maintained in the third and fourth quadrants when entering the water, which is opposite to the forward direction of the hull, and the water-repellent plates are always kept vertical The direction can obtain the maximum thrust for the hull and reduce the water resistance of the water deflector. The gear of the utility model can be made of polytetrafluoroethylene, which can not only obtain good solid lubricating performance, but also reduce noise. The upper support plate 2, the lower support plate 12 and the two water-repellent plates can be made of glass fiber reinforced plastics, which have high strength and can prevent corrosion. As shown in FIG. 4 , the propeller can be symmetrically installed on the power output shaft of the shipboard power machine 15 .

The working principle of the gear linkage mechanism of the present utility model: when the ship-borne power machine 15 rotates, the drive main shaft 9 rotates in the central gear 11, driving the frame consisting of the upper support plate 2 and the lower support plate 12 to rotate, because the central gear 11 is fixed on the ship’s side 8 above, the intermediary gear 13 and the driven gear 7 revolve around the central gear 11 and at the same time drive the shaft 6 and the two water-repelling plates to rotate, and through such gear linkage, the rotation angle of the water-repelling plates is the same as that of the upper support plate 2 and the lower support plate The revolution angle of 12 is equal, and direction is opposite, because the section of water-repelling plate keeps vertical state and is installed on the rotating shaft, so can make the section of the water-repelling plate on two rotating shafts keep vertical direction always.
