Technical Field
[0001] This utility model relates to the field of transport ship technology, and in particular to a pure methanol-powered dual-purpose ship hull device. Background Technology
[0002] The methanol-powered container ship is a multi-functional vessel powered by both methanol and diesel fuels, capable of transporting both containers and bulk cargo, primarily used for inland waterway and coastal shipping. Its core advantage lies in its environmental friendliness: methanol as fuel reduces carbon monoxide emissions by 96% and hydrocarbon emissions by 99%, while its cost is approximately 60% lower than diesel.13 In terms of vessel design, optimized cargo hold layout allows for the mixed loading of standard containers and wide-body rail containers, promoting the development of rail-water intermodal transport.
[0003] When loading cargo, existing methanol distribution vessels typically move the goods to be transported into the cargo hold using hoisting or conveying equipment at the dock. Similarly, unloading is done using the dock's unloading equipment. However, because the cargo hold space cannot be flexibly allocated, these vessels can usually only transport one type of cargo per trip. This makes it impossible to transport other goods when there are fewer cargoes, increasing return transport costs.
[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content
[0005] The purpose of this invention is as follows: When the compression bracket moves upward, the pressure disappears, and the first and second brackets rotate upward in the rotating groove, thereby lowering the height of the entire moving frame and the gate. Since a limiting protrusion is provided on one side of the gate, the limiting protrusion will fall into the inner wall of the slot due to the decrease in height, thus dividing the entire gate into two parts. This allows the dual-purpose vessel to load two different materials at the same time. The existing methanol dual-purpose cargo hold cannot flexibly allocate cargo space, which means that the methanol dual-purpose vessel can usually only transport one type of cargo during a single trip. This results in the inability to transport other cargoes when there are fewer cargoes, increasing the return transport cost.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pure methanol-powered dual-purpose ship hull device, comprising a hull and a cabin, the cabin being disposed on the inner wall of the hull, the inner wall of the cabin being provided with a slot, a sliding frame being provided on the top surface of the hull, a movable frame being mounted on the top surface of the sliding frame, a gate being provided on the bottom surface of the movable frame, a limit protrusion being provided on one side surface of the gate, a rotating groove being provided on the inner wall of the movable frame, a bearing being mounted on the inner wall of the movable frame, a rotating assembly being mounted on the inner wall of the bearing, and a support assembly being mounted on the top surface of the movable frame.
[0007] Furthermore, there are several slots, which are distributed in a linear array at equal intervals on one side and the other side of the inner wall of the cabin. There are two movable frames, which are fixedly connected to one side and the other side of the gate, respectively.
[0008] Furthermore, each of the movable frames has a corresponding rotating groove distributed on its inner wall, and each of the movable frames has two corresponding bearings distributed on its inner wall. The limiting protrusions are two protrusions respectively distributed on one side and the other side surface of the gate. The limiting protrusions are movably inserted into the slots. The bottom surface of the movable frame is in movable contact with the top surface of the sliding frame. The inner wall of the gate is in sliding contact with the inner wall of the cabin.
[0009] Furthermore, the rotating assembly includes a rotating shaft, which is rotatably mounted on the inner wall of the bearing. A first bracket is rotatably mounted on the outer surface of the rotating shaft, and a second bracket is mounted on the outer surface of the rotating shaft. Rubber wheels are rotatably mounted on the inner walls of the first and second brackets.
[0010] Furthermore, the inner walls of the first bracket and the second bracket are in rotatable contact, the outer surfaces of the first bracket and the second bracket are in rotatable contact with the inner wall of the rotating groove, and the rubber wheel is in sliding contact with the top surface of the sliding frame.
[0011] Furthermore, the support assembly includes a contact groove formed on the top surface of the movable frame, a control screw is mounted on the top surface of the movable frame, a control handle is mounted on the top surface of the control screw, and a compression bracket is mounted on the outer surface of the control screw.
[0012] Furthermore, the contact grooves are two equidistantly distributed on the top surface of the movable frame, the control screw is rotatably connected to the movable frame, the extrusion bracket is rotatably connected to the control screw via a thread, one end of the extrusion bracket extends from the inner wall of the contact groove to the inner wall of the rotating groove, and the bottom surface of the extrusion bracket is in movable contact with the top surfaces of the first bracket and the second bracket.
[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0014] This methanol-powered dual-purpose vessel hull device, when the compression support moves upward, the pressure disappears, causing the first and second supports to rotate upward within the rotating groove. This lowers the height of the entire moving frame and the gate. Since a limit protrusion is provided on one side of the gate, the limit protrusion will fall onto the inner wall of the slot due to the decrease in height, thus dividing the entire gate into two parts. This allows the dual-purpose vessel to simultaneously load two different materials. Existing methanol dual-purpose vessels cannot flexibly allocate cargo space, meaning that they can usually only transport one type of cargo on a single trip. This results in the inability to transport other cargoes when there are fewer goods, increasing return transport costs. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.
[0024] like Figures 1-6 As shown, a pure methanol-powered dual-purpose ship hull device includes a hull 1 and a cabin 2. The cabin 2 is located on the inner wall of the hull 1. The inner wall of the cabin 2 is provided with slots 3, and there are several slots 3. The slots 3 are arranged in a linear array and are equidistantly distributed on one side and the other side of the inner wall of the cabin 2. A sliding frame 4 is provided on the top surface of the hull 1. A movable frame 5 is installed on the top surface of the sliding frame 4. There are two movable frames 5. The two movable frames 5 are fixedly connected to one side and the other side of the gate plate 6, respectively. A gate plate 6 is provided on the bottom surface of the movable frame 5. A limit protrusion 7 is provided on one side surface of the gate plate 6. A rotating groove 8 is provided on the inner wall of the movable frame 5. A bearing 9 is installed on the inner wall of the movable frame 5. A rotating component is installed on the inner wall of the bearing 9. A support component is installed on the top surface of the movable frame 5.
[0025] In this embodiment of the present invention, when the compression bracket 17 moves upward, the pressure disappears, and the first bracket 11 and the second bracket 12 will rotate upward in the rotating groove 8, thereby causing the height of the entire moving frame 5 and the gate 6 to drop. Since a limiting protrusion 7 is provided on one side surface of the gate 6, the limiting protrusion 7 will fall into the inner wall of the slot 3 due to the drop in height, thereby causing the entire gate 6 to divide the cabin 2 into two parts, so that the dual-purpose vessel can load two different materials at the same time.
[0026] Each movable frame 5 has a corresponding rotating groove 8 on its inner wall, and each movable frame 5 has two corresponding bearings 9 on its inner wall. There are two limiting protrusions 7 distributed on one side and the other side of the gate plate 6. The limiting protrusions 7 are movably inserted into the slots 3. The bottom surface of the movable frame 5 is in movable contact with the top of the sliding frame 4, and the inner wall of the gate plate 6 is in sliding contact with the inner wall of the cabin 2.
[0027] The rotating assembly includes a rotating shaft 10, which is rotatably mounted on the inner wall of the bearing 9. A first bracket 11 is rotatably mounted on the outer surface of the rotating shaft 10. The inner wall of the first bracket 11 and the second bracket 12 are in rotatable contact. The outer surfaces of the first bracket 11 and the second bracket 12 are in rotatable contact with the inner wall of the rotating groove 8. The second bracket 12 is mounted on the outer surface of the rotating shaft 10. A rubber wheel 13 is rotatably mounted on the inner wall of the first bracket 11 and the second bracket 12. The rubber wheel 13 is in sliding contact with the top surface of the sliding frame 4.
[0028] Reference Figures 1-6 Specifically, the support assembly includes two contact grooves 14, which are equidistantly distributed on the top surface of the movable frame 5. The contact grooves 14 are formed on the top surface of the movable frame 5. A control screw 15 is installed on the top surface of the movable frame 5, and the control screw 15 is rotatably connected to the movable frame 5. A control handle 16 is installed on the top surface of the control screw 15. A pressing bracket 17 is installed on the outer surface of the control screw 15, and the pressing bracket 17 is rotatably connected to the control screw 15 by a thread. One end of the pressing bracket 17 extends from the inner wall of the contact groove 14 to the inner wall of the rotating groove 8. The bottom surface of the pressing bracket 17 is in movable contact with the top surfaces of the first bracket 11 and the second bracket 12.
[0029] In this embodiment of the utility model, when it is necessary to load two different types of cargo on the dual-purpose vessel for collection and distribution, the control handle 16 is grasped and twisted. When the control handle 16 is twisted, it will rotate on the top surface of the moving frame 5. The outer surface of the control handle 16 is rotatably connected to the compression bracket 17 through a thread. Since the compression bracket 17 extends to the inner wall of the contact groove 14, the compression bracket 17, which is limited by the contact groove 14, will not rotate with the control screw 15 when the control handle 16 is rotated. At this time, the compression bracket 17 will move downward along the control screw 15.
[0030] Specific usage procedure: When it is necessary to load two different types of cargo on a dual-purpose vessel, grasp the control handle 16 and twist it. When the control handle 16 is twisted, it will rotate on the top surface of the moving frame 5. The outer surface of the control handle 16 is rotatably connected to the compression bracket 17 through threads. Since the compression bracket 17 extends to the inner wall of the contact groove 14, the compression bracket 17, which is limited by the contact groove 14, will not rotate with the control screw 15 when the control handle 16 is rotated. At this time, the compression bracket 17 will move downward along the control screw 15. When the compression bracket 17 moves downward, it will impact the first bracket 11 and the second bracket 17 on the inner wall of the rotating groove 8. The two are squeezed together. When they are squeezed by the squeezing bracket 17, they will rotate on the inner wall of the rotating groove 8. Rubber wheels 13 are installed at the ends of the first bracket 11 and the second bracket 12. At this time, because the rotating rubber wheel 13 will contact the top surface of the sliding frame 4, as the squeezing bracket 17 continues to squeeze, the rotation angle of the first bracket 11 and the second bracket 12 will gradually increase. At this time, the first bracket 11 and the second bracket 12 will lift the entire moving frame 5 and the gate 6 through the rotating shaft 10. When the gate 6 is lifted, it will push the two moving frames 5 to move the gate 6 along the top surface of the sliding frame 4, thereby realizing the movement of the gate 6.
[0031] When the vessel moves to the designated position, the control handle 16 is rotated in the reverse direction, causing the compression bracket 17 to move upward along the control screw 15. As the compression bracket 17 moves upward, the pressure disappears, and the first bracket 11 and the second bracket 12 rotate upward within the rotating groove 8, thereby lowering the height of the entire moving frame 5 and the gate 6. Since a limit protrusion 7 is provided on one side of the gate 6, the limit protrusion 7 will fall onto the inner wall of the slot 3 due to the decrease in height, thus dividing the cabin 2 into two parts, allowing the dual-purpose vessel to load two different materials simultaneously.
[0032] The methanol storage tank of the methanol distribution vessel is completely enclosed in the main hull, and the methanol filling port is more than 15 meters away from the crew living area, thus complying with the International Maritime Organization (IMO) Provisional Guidelines on the Safety of Ships Using Methanol as Fuel.
[0033] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
