Description

Technical Field

[0001] The invention belongs to the field of ship construction and design, and in particular relates to a recyclable composite material rotor sailboat. Background Art

[0002] The use of wind energy is a technology that has been re-proposed in the field of energy conservation and emission reduction of international ships in recent years. Wind energy not only meets the requirements of environmental protection, but also caters to the idea of ​​shipping companies to pursue cost-effectiveness. Therefore, in recent years, ocean-going ships have gradually begun to develop in the direction of wind energy-assisted navigation. Although wind power cannot completely replace ship fuel, it can reduce the ship's carbon dioxide emissions and save fuel consumption.

[0003] In recent years, marine sails are mainly divided into two types: wing-shaped sails and rotor sails. The rotor sail is a vertical cylindrical device installed on the deck of the ship. During the voyage, the cylinder is driven by a motor to rotate. When passing through the natural wind field at sea, it uses the aerodynamic phenomenon called the Magnus effect to generate thrust, providing power for the ship to move forward, saving fuel and reducing emissions.

[0004] The problem is:

[0005] (1) In the prior art, the cross-sectional area of ​​the wing-shaped sail is large. Regardless of the form of the wing-shaped sail, the space occupied by the wing-shaped sail after recovery is relatively large. Therefore, most of the existing wing-shaped sails still stand on the ship deck after recovery, which causes the center of gravity of the ship to be high, affecting the stability of the ship, especially in dangerous working conditions, causing safety hazards to the ship.

[0006] (2) Compared with wing-shaped sails, rotor sails occupy less space and have better recyclability. Most of the existing technologies adopt the solution of placing the rotor on the deck. The higher the size of the rotor sail, the better the effect. Therefore, even if the rotor sail still has a height of 6m after being retracted, a rotor that is too high will affect the ship's ability to pass through the bridge. There is a solution in the existing technology that places the rotor in the middle of the hull and the rotor base is placed on the double bottom. The mast diameter is proportional to the height. If the height of this solution reaches the requirement, the cargo hold capacity will be lost, and the mast height will be lost to ensure the hold capacity. The two cannot be achieved at the same time.

[0007] (3) As a mechanical structure, the rotor sail is generally made of steel structure. Due to its high height and heavy weight, it affects the overall stability of the ship. The sail structure with a small cylindrical radius is not conducive to the welding of reinforcement ribs.

[0008] (4) Placing existing sails on the deck will make the deck crane unable to operate. Therefore, if we want to promote and apply sail technology to other ship types, we must solve the problem of interference between the sails on the deck and the deck crane and free up deck space.

[0009] Therefore, how to avoid the above risks when necessary is a major problem facing the design of rotor sails. Summary of the invention

[0010] In order to solve the above problems, the present invention provides a recyclable composite material rotor sailboat, which aims to achieve the purpose of occupying a small space, reducing the overall height of the ship, and ensuring the stability of the ship.

[0012] The lifting platform has a horizontally placed top plate and a bottom plate, the bottom plate is fixed on the inner bottom of the recovery cabin, a rectangular slide groove is fixed on the edge of the bottom plate, one end of the slide groove is closed and the other end is open, a spring is provided at the closed end of the slide groove, a block is fixed on the bottom plate near the open end of the slide groove, the cylinder body of the hydraulic cylinder is fixedly connected to the block, the bottom of the cylinder body has an oil port, a piston block is provided in the hydraulic cylinder, a steel rod is fixedly connected to the piston block, the steel rod extends out of the cylinder body, passes through the block and extends into the slide groove, and presses on the spring.

[0013] The top plate is arranged above the bottom plate through a telescopic frame, the top of the telescopic frame is hinged to the top plate, one side of the bottom of the telescopic frame is connected to the bottom plate through a fixed support, the fixed support is fixed to the bottom plate, one side of the telescopic frame is hinged to the fixed support, and the other side is fixedly connected to the steel rod in the slide groove through a sliding support, and the other side of the bottom of the telescopic frame is hinged to the sliding support.

[0014] The telescopic mast is divided into three sections, which are the first mast section, the second mast section, and the third mast section from top to bottom. The first mast section, the second mast section, and the third mast section are hydraulically driven, and a cylindrical sail is fixed on each mast section. The diameter of the sail surface from the first mast section to the third mast section gradually decreases, and they are stacked from top to bottom.

[0015] The top and bottom of the recovery cabin are provided with multiple C-shaped reinforcement structures, which are arranged circumferentially along the outer surface of the recovery cabin. The C-shaped reinforcement structure has a spring limiter, which passes through the recovery cabin wall and is inserted into the fixed groove hole. Photosensitive sensors are arranged on the lower surface of the deck and above the shell, and the photosensitive sensors are connected to the spring limiter signals.

[0016] The above-mentioned recyclable composite material rotary sailboat, further, has a plurality of groove reinforcement structures fixed at equal intervals along the circumference of the cylindrical sail surface, the groove reinforcement structures are installed on the cylindrical sail surface in an insert-type manner, and a buckle groove is provided above the groove reinforcement structure and a limiting buckle is provided below.

[0017] The above-mentioned recyclable composite material rotary sailboat, further, has a suction port at the bottom of the recovery cabin, and the suction port is connected to the sewage tank.

[0018] The above-mentioned recyclable composite material rotor sailboat, further, has a plurality of C-shaped reinforcement structures arranged at equal intervals.

[0019] The above-mentioned recyclable composite material rotor sailboat further has a sail surface made of composite material.

[0020] The above-mentioned recyclable composite material rotor sailboat, further, has a spacing of 80 mm to 100 mm between the shell and the bulkhead in the recovery cabin.

[0021] In the above-mentioned recyclable composite material rotary sailboat, further, two sets of the telescopic frames and the slide grooves are symmetrically arranged between the top plate and the bottom plate, and the angle a formed by the telescopic frames is greater than 30°.

[0022] In the above-mentioned recyclable composite material rotor sailboat, further, the shell and the recovery cabin are both circular.

[0023] The above-mentioned recyclable composite material rotor sailboat further has an annular reinforcement structure fixed between adjacent C-shaped reinforcement structures.

[0024] The above-mentioned recyclable composite material rotor sailboat, further, the recovery cabin is equipped with a circular hatch cover.

[0025] The beneficial effects of the present invention are as follows:

[0026] (1) The rotary sail device occupies a small space and can be completely retracted into the cabin, which can protect the sail structure from danger when encountering dangerous sea conditions. At the same time, it can also reduce the space occupied by the sail structure on the deck, without blocking the line of sight and affecting the ship's passage through the bridge.

[0027] (2) Setting up a lifting platform can reduce the space occupied by the sail device in the cabin. If the lifting platform is not used, the sail mast needs to lift the sail out of the cabin first and then raise the sail, which wastes the height of the sail in the cabin. Since the rotor-type sail is as high as possible, the energy-saving effect is reduced by half.

[0028] (3) A recovery cabin structure is provided, which can be used as a recovery structure for the sail and also as a reinforcement base for the sail. This means that when in use, the force can be transmitted to the hull structure, which can better bear the force. The recovered sail can reduce the metacentric height of the entire hull, which is beneficial to the stability of the hull.

[0029] (4) The composite sail surface combined with the groove-type reinforcement structure allows the sail surface to be installed without welding, avoiding the problem of welding operations in narrow spaces. In addition, the composite material is strong enough and light in weight, which is a great advantage.

[0030] (5) Since cylindrical sails are small, multiple sets can be installed on a ship without blocking the line of sight.

[0031] (6) Solve the interference problem between deck crane and sail.

[0032] (7) Since there is a deck crane on the deck of a bulk carrier, ore carrier or container ship, if the sail is installed above the deck, the deck crane will not work. Therefore, this patent mainly solves the problem of insufficient deck operation space. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The present invention will be further described in conjunction with the accompanying drawings.

[0041] A recyclable composite material rotor sailboat, such as Figure 1 , 2 As shown in FIG. 3 , a circular telescopic mast recovery cabin is provided below the deck 7, and a lifting platform (such as Figure 5 , 6 As shown in the figure, the telescopic mast 5 is placed in the recovery cabin, the telescopic mast is fixed on the lifting platform, and the recovery cabin is equipped with a hatch. The bottom of the telescopic mast is riveted to the slewing mechanism through the base 3. The slewing mechanism has a circular external shell 2. The slewing mechanism can provide the rotational power of the mast. There is a distance of 80mm to 100mm between the shell and the wall of the recovery cabin. The shell is fixed on the lifting platform, and a plurality of fixed groove holes 15 are opened on the side wall of the shell and along the circumference of the shell. The lifting platform is fixed on the bottom plate of the recovery cabin. A suction port is opened at the bottom of the recovery cabin, and the suction port is connected to the sewage tank 11. The suction port can discharge the sewage in the cabin into the sewage tank.

[0042] like Figure 5 , 6 As shown, the lifting platform has a horizontally placed top plate 105 and a bottom plate 101. The bottom plate is riveted to the bottom of the recovery cabin, the sail base is riveted to the top plate, a rectangular slide 102 is fixed on the edge of the bottom plate, one end of the slide is closed and the other end is open, a spring 106 is arranged at the closed end of the slide, a block 109 is fixed near the open end of the slide on the bottom plate, the cylinder body 111 of the hydraulic cylinder is fixedly connected to the block, the bottom of the cylinder body is provided with an oil port 112, a piston block 110 is arranged in the hydraulic cylinder, a steel rod 107 is fixedly connected to the piston block, the steel rod extends out of the cylinder body, passes through the block and extends into the slide, and presses on the spring. The piston block moves back and forth in the cylinder body, driving the steel rod to extend left and right in the slide. Two sets of telescopic frames and slides are symmetrically arranged between the top plate and the bottom plate.

[0043] The top plate is arranged above the bottom plate through a telescopic frame 103. The telescopic frame is telescopic up and down, and the whole is square. The top of the telescopic frame is hinged with the top plate, and one side of the bottom of the telescopic frame is connected to the bottom plate through a fixed support 104. The fixed support is fixed to the bottom plate. One side of the telescopic frame is hinged with the fixed support, and the other side is fixedly connected to the steel rod in the slide groove through a sliding support 108. The other side of the bottom of the telescopic frame is hinged with the sliding support. When the piston block is pushed to the stopper, the lifting platform reaches the highest point, and the angle a formed between the two rods of the telescopic frame is a>30°.

[0044] The hydraulic cylinder pushes the piston block through the oil port, and the steel rod drives the sliding support. The lifting platform rises, and the spring is compressed to give a reaction force to the sliding support, and the sliding support is fixed. When the lifting platform descends, the pressure is released, and the spring will push the sliding support toward the block, and the lifting platform descends. At this time, the platform descends to the lowest point.

[0045] The telescopic mast is divided into three sections, which are the first mast section, the second mast section and the third mast section from top to bottom. The first mast section, the second mast section and the third mast section are hydraulically driven. A cylindrical sail surface 6 is fixed on each mast section. The cylindrical sail surface is made of hard composite material. The composite material can adopt carbon fiber unidirectional tape prepreg with model UDCF300 / MT0928Z. The use of composite material sail surface avoids the problem of welding operation in a narrow space. At the same time, the composite material can reduce weight while ensuring strength and has good flexibility.

[0046] The diameter of the sails from the first mast to the third mast gradually decreases, and they are stacked from top to bottom. Figure 4 As shown, a groove reinforcement structure 12 is fixed every 15° along the circumference of the cylindrical sail surface. The groove reinforcement structure is installed on the cylindrical sail surface in an inserted manner. A buckle groove 13 is provided above the groove reinforcement structure, and a limit buckle 14 is provided below. The groove reinforcement structure forms a closed space. During installation, the buckle groove allows the groove reinforcement structure to only move up and down on the sail surface. After installation, the groove reinforcement structure will not be able to move because it is stuck by the limit buckle. It is combined with the sail surface and does not require bonding and welding. The limit buckle is to limit the up and down movement of the groove reinforcement structure. One side of the limit buckle is the fixed side, which needs to be slid into position and installed after the groove structure is installed.

[0047] Multiple C-shaped reinforcement structures are arranged on the top and bottom of the recovery cabin. The multiple C-shaped reinforcement structures are arranged at equal intervals along the circumference of the outer surface of the recovery cabin, and an annular reinforcement structure is fixed between adjacent C-shaped reinforcement structures. The C-shaped reinforcement structure and the annular reinforcement structure support each other to form a truss structure, which is convenient for personnel to go up for maintenance and can be used as a maintenance channel. The C-shaped reinforcement structure has a spring limiter 16, which passes through the recovery cabin wall and is inserted into the fixed groove hole 15. A photosensitive sensor 17 is arranged on the lower surface of the deck and above the shell, and the photosensitive sensor is connected to the spring limiter signal.

[0048] When the upper surface of the slewing mechanism approaches the deck, the photosensitive sensor can sense the circular opening and sense traditional light. That is, when the fixed groove hole and the spring limiter are aligned, the photosensitive sensor transmits the signal to the control room. The control room checks the accuracy of the position and then opens the spring limiter. The spring limiter bounces into the circular fixed groove hole and fixes it there.

[0049] Sail workflow:

[0050] (1) Initial state: the rotor sail is in the retracted state.

[0051] (2) Working state: Open the hatch cover of the recovery cabin, turn on the lifting platform, and lift the mast above the deck. At this time, the light sensor installed under the deck senses the penetrating light and automatically turns on, popping out the spring limiter into the circular fixed groove hole on the slewing mechanism housing, limiting the slewing mechanism here, turning on the sail mast device, raising the sail to the highest point, turning on the slewing mechanism, and the sail is in working state.

[0052] (3) Recovery state: close the sail slewing mechanism and lower the sail, overlap the first section of the sail surface on the third section of the sail surface, and fold the sail. Rebound the spring limiter, open the lifting platform, retract the sail structure into the cabin, and close the recovery cabin cover.

[0053] 1. Use a rotor-type sail, design a rotor with a matching diameter according to its height, set a recovery cabin on the outside of the rotor, set it in the cargo hold area, the recovery cabin is clean, the sail can be completely recovered into the cabin, and a recovery hatch cover is set on the deck to prevent water from entering the cabin. Lower the weight center of the sail placed on the deck.

[0054] 2. A hydraulic lifting platform is arranged on the inner bottom, the rotor sail base is installed on the platform, a mast is arranged on the base, and a rotating mechanism is arranged inside the base, which can make the rotor rotate, and utilize the aerodynamic phenomenon of the Magnus effect to generate thrust, provide power for the ship to move forward, save fuel and reduce emissions.

[0055] 3. A groove is arranged on the rotor sail base, a spring thimble is arranged in the recovery cabin, and the lower lifting platform and the spring thimble can fix the sail base in the recovery cabin. The strength of the sail is ensured by arranging a counter-position reinforcement structure in the recovery cabin.

[0056] 4. A hydraulic lifting platform is arranged on the inner bottom to first lift the rotor sail as a whole to the deck, and the sail mast then lifts the rotor sail to a specified height, so that the rotor sail has a larger deck exposure and wind receiving area, and can be completely placed in the cabin after being recovered, without occupying the deck space and blocking the line of sight.

[0057] 5. Composite materials are used to replace the steel structure of the rotor, and grooved buckles are used on the rotor, which can eliminate the reinforcing ribs on the inside of the rotor.
