Description

Technical Field

[0001] The utility model relates to the technical field of ship construction, in particular to a ship thruster structure and a ship. Background Art

[0002] With the acceleration of economic globalization and the increasing prosperity of world trade, the shipping industry, as a bridge connecting the world, has become increasingly important and continues to show strong development momentum. This trend has directly promoted the upgrading of port facilities and the innovation of ship technology to meet the growing demand for cargo transportation. With the significant increase in port ship traffic and density, how to efficiently and safely manage the navigation of these behemoths has become an urgent problem to be solved. In this context, the requirements for ship maneuverability and maneuverability have been raised to an unprecedented level, especially in narrow port areas and complex water environments.

[0003] The emergence of bow thrusters is precisely to solve this technical problem. This innovative design installs a thruster at the bow of the ship as an auxiliary propulsion system, which greatly enhances the ship's steering flexibility and lateral movement ability at low speeds. In busy port waters, bow thrusters enable ships to easily complete precise course adjustments, effectively avoiding the risk of collision and improving operational efficiency. In addition, in restricted waters or when sailing at close range, bow thrusters can also effectively overcome the "bank effect" and "inter-ship effect", that is, the difficulty in maneuvering caused by changes in water flow when the ship is close to the shore or other ships, ensuring the stability and safety of navigation.

[0004] However, in order to achieve the best performance of the thruster during ship construction, the traditional practice is to perform secondary processing on the hull after completion to open thruster holes that match the thruster. This process is not only complicated and costly, but more importantly, it may weaken the structural strength of the hull, especially burying hidden dangers in the stability of the connection parts. At the same time, since the accuracy of the opening is difficult to ensure, the thruster effect may be discounted and even affect the overall performance of the ship. In addition, seawater can easily impact the inner wall of the thruster hole during the ship's forward movement, increasing navigation resistance and adversely affecting the speed and stability of the ship. Utility Model Content

[0005] In view of this, the purpose of the present invention is to overcome the deficiencies in the related art. The present invention provides a ship thruster structure and a ship.

[0006] The utility model provides the following technical solutions:

[0007] A ship thrust structure is arranged on a hull of the ship. The ship thrust structure comprises a thrust hole and a thrust assembly.

[0008] The side thrust hole passes through from one side wall of the hull to the other side wall of the hull, and a guide groove corresponding to the side thrust hole is provided on the side wall of the hull. The guide groove is communicated with the side opening of the side thrust hole, and the guide groove is arranged on the side of the side opening of the side thrust hole away from the bow of the hull; the side thrust assembly is arranged in the side thrust hole to provide side thrust for the heading adjustment of the ship.

[0009] As a further improvement of the above technical solution, the side thrust hole on the hull is formed at one time through a prefabricated side thrust hole mold during the processing and manufacturing of the hull.

[0010] As a further improvement of the above technical solution, the axis of the side thrust hole is perpendicular to the moving direction of the hull.

[0011] As a further improvement of the above technical solution, the side thrust hole is opened at a position close to the bow of the hull.

[0012] As a further improvement of the above technical solution, the depth of the guide groove gradually decreases from a side close to the side push hole to a side far away from the side push hole.

[0013] As a further improvement of the above technical solution, the side thrust assembly includes a power device and a propeller. The power device is arranged in the side thrust hole, the power device is transmission-connected to the propeller, and the power device is used to drive the propeller to rotate forward and reverse.

[0014] As a further improvement of the above technical solution, the power device includes a drive motor, which is installed in the side thrust hole through a support frame, and the rotating shaft of the propeller is drivingly connected to the motor shaft of the drive motor.

[0015] As a further improvement of the above technical solution, the support frame is composed of a plurality of support plates, and the support plates are evenly distributed in the circumferential direction of the drive motor relative to the axis of the drive motor. The drive motor is fixedly connected to the inner wall of the side thrust hole through the support plates, and the plate surface of the support plates is parallel to the radial surface of the side thrust hole.

[0016] As a further improvement of the above technical solution, the support plate changes from thick to thin from the middle to the two ends.

[0017] As a further improvement of the above technical solution, two propellers are symmetrically provided relative to the power device.

[0018] As a further improvement of the above technical solution, the thrust assembly also includes a control module, and the control module is electrically connected to the power device.

[0019] As a further improvement of the above technical solution, the side thrust assembly is located in the middle of the side thrust hole.

[0020] The utility model also provides a ship, comprising any one of the ship thruster structures described above.

[0021] Compared with the related art, the beneficial effects of the utility model are:

[0022] The utility model aims to provide a thruster structure for ships, which cleverly combines the principles of fluid mechanics and ship engineering practice to significantly improve the navigation stability and maneuverability of ships. Specifically, the design first sets through thruster holes on both sides of the hull of the ship. The layout of these holes is accurately calculated to ensure that the water flow power is maximized without affecting the overall structural strength of the hull. Subsequently, a thruster assembly is arranged inside the thruster hole to provide thrust for the course adjustment of the ship. At the same time, in order to further optimize the water flow path and reduce the direct impact of the water flow on the inner wall of the thruster hole, a guide groove connected to the side opening of the thruster hole is opened on the side wall of the hull at a position corresponding to the thruster hole. These guide grooves can effectively guide the water flow to pass smoothly and reduce the generation of turbulence, thereby significantly reducing the water resistance encountered by the ship during navigation and improving navigation efficiency and stability.

[0023] When a ship is sailing in open waters, the natural water flow will flow freely from both sides of the hull and be effectively guided by the guide grooves when passing through the thrust holes. This process not only reduces the impact load of the water flow on the inner wall of the thrust hole, but also indirectly improves the ship's speed and fuel economy by reducing water resistance. Once the ship needs to enter a narrow port area or face a complex and changeable water environment and make fine deflection adjustments or course changes, the thrust assembly plays a key role. By starting the thrust assembly, the thrust assembly can quickly generate strong water flow power in the thrust hole, efficiently pumping the water flow on one side of the hull to the other side, forming a reverse thrust. This instant and precise thrust control enables the ship to complete deflection or course adjustment in a very short time, greatly enhancing the ship's maneuverability and safety in complex environments.

[0036] Example 1

[0037] like Figure 1 As shown, this embodiment provides a ship thrust structure, which is arranged on a hull 100 of a ship. The ship thrust structure includes a thrust hole 110 and a thrust assembly 200 .

[0038] The side thrust hole 110 passes through from one side wall of the hull 100 to the other side wall of the hull 100. A guide groove 120 corresponding to the side thrust hole 110 is provided on the side wall of the hull 100. The guide groove 120 is communicated with the side opening of the side thrust hole 110. The guide groove 120 is arranged on the side of the side opening of the side thrust hole 110 away from the bow of the hull 100; the side thrust assembly 200 is arranged in the side thrust hole 110 to provide side thrust for the heading adjustment of the ship.

[0039] The thrust structure for ships provided in this embodiment firstly sets through thrust holes 110 on both sides of the hull 100 of the ship. The layout of these holes has been precisely calculated to ensure that the water flow power is maximized without affecting the overall structural strength of the hull 100. Subsequently, a thrust assembly 200 is set inside the thrust hole 110 to provide thrust for the course adjustment of the ship. At the same time, in order to further optimize the water flow path and reduce the direct impact of the water flow on the inner wall of the thrust hole 110, a guide groove 120 connected to the side opening of the thrust hole 110 is opened on the side wall of the hull 100 at a position corresponding to the thrust hole 110. These guide grooves 120 can effectively guide the water flow to pass smoothly and reduce the generation of turbulence, thereby significantly reducing the water resistance encountered by the ship during navigation and improving navigation efficiency and stability.

[0040] When a ship is sailing in open waters, the natural water flow will flow freely from both sides of the hull 100, and will be effectively guided by the guide groove 120 when passing through the side thrust hole 110. This process can effectively reduce the impact load of the water flow on the inner wall of the side thrust hole 110. Once the ship needs to enter a narrow port area or face a complex and changeable water environment and make fine deflection adjustments or course changes, by starting the side thrust assembly 200, the side thrust assembly 200 can quickly generate a strong water flow power in the side thrust hole 110, and efficiently pump the water flow on one side of the hull 100 to the other side, forming a reverse side thrust. This instant and precise side thrust control enables the ship to complete deflection or course adjustment in a very short time, greatly enhancing the ship's maneuverability and safety in complex environments.

[0041] In some embodiments, the side thrust hole 110 on the hull 100 is formed at one time by a prefabricated side thrust hole 110 mold along with the processing and manufacturing of the hull 100. By forming the hull 100 and the side thrust hole 110 at one time, it is convenient to ensure the overall structural strength of the hull 100 and improve the processing efficiency; specifically, in the process of carefully manufacturing the hull 100, the design and manufacture of the side thrust hole 110 are directly integrated into the layering process, which not only improves the production efficiency, but also ensures the perfect fit between the side thrust hole 110 and the structure of the hull 100. The layering work needs to be meticulous, and each layer of material needs to be laid accurately to ensure the strength and stability of the hull 100. As the layers are stacked layer by layer, the position and shape of the side thrust hole 110 gradually appear, and it is integrated with the hull 100. After the layering is completed, the next step is the key resin infusion. The use of advanced vacuuming technology can effectively remove air and bubbles between materials and create the best conditions for the uniform distribution of resin. The resin is slowly injected under vacuum, penetrates between the fibers, and is tightly bonded to the fibers through chemical reactions to form a strong and light composite material structure. This process not only enhances the overall strength of the hull 100, but also significantly improves its corrosion resistance and durability. After the resin is fully cured, the hull 100 has the required physical properties and shape. At this point, it can be smoothly removed from the mold and enter the subsequent processing stage.

[0042] In some embodiments, the axis of the side thrust hole 110 is perpendicular to the travel direction of the hull 100, so that the direction of the water flow power generated by the side thrust assembly 200 in the side thrust hole 110 is perpendicular to the travel direction of the ship, thereby improving the adjustment efficiency of the ship.

[0043] In some embodiments, the thrust holes 110 are carefully arranged in an area close to the bow of the hull 100. This layout strategy significantly enhances the ability of the hull 100 to adjust the bow direction during navigation. Through the operation of the thrust device, especially when it is necessary to quickly change the course or keep the ship stable, the thruster in the thrust hole 110 can generate lateral thrust, which directly acts near the bow, so that the hull 100 can respond to the control command more quickly and accurately, and realize the flexible adjustment of the bow direction. This design not only improves the ship's ability to respond in complex waters or emergency situations, but also optimizes the overall control performance of the ship, ensuring the safety and efficiency of navigation.

[0044] In some embodiments, the depth of the guide groove 120 gradually decreases from the side close to the side thrust hole 110 to the side far away from the side thrust hole 110, so that the guide groove 120 can gradually guide the water flow to the side surface of the hull 100 when guiding the water flow, thereby fully diverting and dispersing the water flow impact at the side thrust hole 110.

[0045] Combination Figure 2 , Figure 3 As shown, in some embodiments, the side thrust assembly 200 includes a power device 210 and a propeller 220. The power device 210 is disposed in the side thrust hole 110. The power device 210 is transmission-connected to the propeller 220. The power device 210 is used to drive the propeller 220 to rotate forward and reversely. The forward and reverse rotation of the propeller 220 can generate a suction force in the side thrust hole 110. The structure is simple and ingenious, and is convenient for later maintenance.

[0046] In some embodiments, the power device 210 includes a drive motor 211, which is installed in the side thrust hole 110 through a support frame 230, and the rotating shaft of the propeller 220 is drivingly connected to the motor shaft of the drive motor 211; the principle is simple and easy to maintain.

[0047] In some embodiments, the support frame 230 is composed of a plurality of support plates, and the support plates are evenly distributed in the circumference of the drive motor 211 relative to the axis of the drive motor 211. The drive motor 211 is fixedly connected to the inner wall of the side thrust hole 110 through the support plates, and the plate surface of the support plates is parallel to the radial surface of the side thrust hole 110. By using a plurality of the support plates to install the drive motor 211 in the side thrust hole 110, the resistance of the support frame 230 to the water flow can be effectively reduced, thereby ensuring the use effect of the side thrust assembly 200.

[0048] In some embodiments, the support plate changes from thick to thin from the middle to the two ends, further reducing the resistance of the support plate to water flow.

[0049] In some embodiments, two propellers 220 are symmetrically arranged relative to the power device 210 to further improve the suction effect of the side thrust assembly 200 .

[0050] In some advanced embodiments, the intelligence and automation level of the thrust assembly 200 has been significantly improved, which is mainly due to the introduction of its built-in control module. The control module plays a vital role as the "brain" of the thrust system. It not only realizes electrical connection with the power unit 210 (including key components such as the drive motor 211), ensuring the unimpeded power transmission and control instructions, but also integrates advanced control algorithms and logical judgment functions. Through electrical connection, the control module can receive operating instructions from the ship's bridge or other control systems in real time, such as heading adjustment, side thrust, etc., and quickly convert them into corresponding control signals and send them to the power unit 210. After receiving these control signals, the power unit 210 will accurately adjust its working state, such as changing the speed and direction of the drive motor 211, thereby driving the propeller 220 to generate the required lateral thrust, and realizing flexible adjustment or stable control of the ship's heading.

[0051] In some embodiments, the thrust assembly 200 is located in the middle of the thrust hole 110; when the thrust assembly 200 is located in the middle of the thrust hole 110, it can provide thrust to both sides of the hull 100 in the most balanced way. Whether it is the port or starboard side, the thrust assembly 200 can output the corresponding thrust in the same working state and parameters. This symmetrical and identical working mode greatly simplifies the control process and reduces the difficulty of control. When the crew adjusts the course or performs complex operations, they only need to send a unified command through the control module to achieve the synchronous adjustment of the thrust on both sides, without the need to perform cumbersome operations on both sides, thereby improving the control efficiency and accuracy. In addition, the layout of the thrust assembly 200 in the middle also helps to improve the navigation stability of the ship. When encountering adverse environments such as wind and waves, the symmetrical thrust on both sides can better resist external interference and keep the hull 100 sailing smoothly. At the same time, this layout also helps to reduce adverse phenomena such as torsion of the hull 100 caused by unbalanced thrust, further improving the navigation safety of the ship. In summary, arranging the thrust assembly 200 in the middle of the thrust hole 110 is one of the important measures to improve the ship's control performance and navigation stability. This layout not only simplifies the control process, improves control efficiency and accuracy, but also helps to improve the ship's navigation stability and safety in complex environments.
