Description

Technical Field

[0001] The present invention belongs to the technical field of multiple ship fleets, and more specifically, relates to a propeller propulsion cabin for multiple ship fleets. Background Art

[0002] Typically, a ship's propeller or thruster is installed within the hull at the stern. Some smaller vessels also install thrusters on the deck. In fleets of multiple ships linked end-to-end, to avoid the impact of the thruster's wake on the following ships, a propeller is typically only installed at the stern of the last ship. However, due to the limited number of propellers and propulsion power, increasing speed is difficult. While fleets offer advantages such as high capacity, low resistance, low transportation costs, flexible transshipment, and increased navigability, their centralized propulsion system results in low speed, poor safety, and maneuverability. This makes maneuvering in narrow waterways difficult, making steering difficult and potentially disrupting normal navigation. Among existing propulsion methods, such as propellers, jets, and rudder propellers, propeller propulsion is currently the most commonly used. Its simple structure and light weight make it suitable for most ships, but at high speeds, due to the high friction and resistance, it can produce significant noise and vibration. Jet propellers offer the advantages of fast response and high speed, making them suitable for high-speed vessels. However, their complex structure and high maintenance costs are associated with high maintenance costs. Rudder propulsion, similar to a rudder, can both control the ship's direction and generate thrust. It's suitable for ships that need to make frequent turns and operate in confined waters, but its propulsion efficiency is relatively low. Existing propulsion methods are typically installed inside the hull at the stern of a ship and can only be used in designated locations. When thrusters are installed inside the hulls at the stern of each ship in a fleet, theoretically, converting centralized power to distributed power could improve the fleet's maneuverability and increase its speed. However, in practice, the fact that the rudder propulsion compartments are mounted on the deck inevitably creates wake accumulation, reducing propulsion efficiency.

[0003] The prior art includes a technology titled "A Ship Propeller and Ship Thereof" with publication (announcement) number "CN207943151U." This technology provides a ship propeller that utilizes a slide plate, two rotatable tilting mechanisms, and a bevel gear set connected to a motor. The reciprocating blades tilt at specific positions to provide thrust to the ship. The technology has high propulsion efficiency and is simple to manufacture. Ships, warships, and submarines can be powered by internal combustion engines, nuclear power, batteries, or human power, and is noiseless and pollution-free. However, this technology does not address the technical problems and technical solutions of the present application. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in view of the shortcomings of the existing technology, a propeller propulsion cabin for a multi-ship fleet is provided which has a simple structure, high maneuverability and flexibility of the rudder propeller, and the propulsion cabin body can be pushed out laterally to prevent interference from the preceding ship, reduce wake accumulation, and improve propulsion efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is:

[0006] The present invention is a propulsion cabin for a multi-ship fleet, comprising a propulsion cabin body, a moving mechanism, and a locking mechanism. The moving mechanism comprises a moving slide rail, a connecting slide, a telescopic component of the moving mechanism, and a fixed base. The fixed base is fixed to the ship body, the connecting slide is arranged on the fixed base, the moving slide rail is movably mounted on the connecting slide, one end of the telescopic component of the moving mechanism is connected to the fixed base located inside the ship body, and the other end of the telescopic component of the moving mechanism is connected to the propulsion cabin body. An engine is arranged on the propulsion cabin body, and the engine is connected to the rudder propeller through a transmission shaft. A card block is arranged on the moving track, and a locking mechanism is arranged near the moving track. The locking mechanism comprises a first clamp, a second clamp, and a telescopic component of the locking mechanism.

[0007] The fixed base is parallel to the side of the ship body of the ship body, and the fixed base is respectively arranged at the front of the ship body near the side of each side of the ship body.

[0008] The connecting slide is arranged perpendicular to the side of the ship body, and the connecting slide is arranged at the front of the ship body close to each side of the ship body, and each movable track is connected to the propulsion cabin body.

[0009] The telescopic components of the moving mechanism are perpendicular to the side of the ship body, and the telescopic components of the moving mechanism are respectively arranged at the front of the ship body close to the side of each side of the ship body.

[0010] The fixed bases are arranged in parallel in multiple lanes, and the movable tracks are arranged in parallel in multiple lanes.

[0011] A clamping block is provided at one end of the movable track near the end position.

[0012] The locking mechanism telescopic rod of the locking mechanism is connected to the movable track arrangement, one end of the locking mechanism telescopic rod is connected to the first hoop, and the other end of the locking mechanism telescopic rod is connected to the second hoop, and the first hoop and the second hoop are movably sleeved on the positioning rod.

[0013] A locking mechanism is provided near one end of the connecting slide, and another locking mechanism is provided near the other end of the connecting slide. A limit switch is provided at the outer end of the positioning rod of each locking mechanism, and a limit switch is provided near each end of the connecting slide.

[0014] The moving mechanism telescopic component and the locking mechanism telescopic component are hydraulic cylinders, and each limit switch, moving mechanism telescopic component and locking mechanism telescopic component are respectively connected to the control component.

[0015] The present invention also relates to a control method for a propeller propulsion cabin of a multi-ship fleet, which has simple steps, high maneuverability and flexibility of the rudder propeller, and the propulsion cabin body can be pushed out sideways to prevent interference from the preceding ship, reduce wake accumulation, and improve propulsion efficiency. The control steps of the control method for the propeller propulsion cabin of a multi-ship fleet are as follows:

[0016] S1. When the propulsion module is about to move outward, the control component controls the extension of the locking mechanism's telescopic component located on the inner side of the locking mechanism, driving the first and second clamps of the locking mechanism to move relative to the positioning rod and away from the block. When the clamps are released to the limit position, the limit switch is triggered. The limit switch sends a feedback signal to the control component, which controls the extension of the telescopic component of the moving mechanism. The extension of the telescopic component of the moving mechanism pushes the sliding rail outward along the connecting slide, and the propulsion module extends outward.

[0017] S2. When the telescopic component of the moving mechanism extends outward and reaches its limit position, the limit switch is triggered, causing the telescopic component of the locking mechanism on the outer side locking mechanism to retract, driving the first and second clamps of the locking mechanism to move relative to the positioning rod and approach the block, completing the locking of the block. The propulsion module body completes its outward movement, enters the push-out state, and is locked after being pushed out.

[0018] S3. When the propulsion cabin body is retracted inward, the control component controls the locking mechanism located on the outside to release the lock on the block of the moving track, and then the telescopic component of the moving mechanism contracts, driving the moving track to move inward along the connecting slide. When the inward contraction reaches the limit position, the limit switch is triggered, and the locking mechanism located on the inside locks the block of the moving track. The propulsion cabin body completes the inward movement and enters the contracted state, and is locked after contraction.

[0019] The technical solution of the present invention is adopted, and the working principle and beneficial effects are as follows:

[0020] The propulsion compartment for a multi-ship fleet of ships of the present invention is structured such that a propulsion compartment body, a moving mechanism, and a locking mechanism are separately manufactured. The propulsion compartment body is used to arrange the rudder propellers and realize the propulsion or retreat control of the ship. The moving mechanism is used to realize the retraction and extension control of the propulsion compartment body. The locking mechanism is used to lock the propulsion compartment body by locking the moving track when the propulsion compartment body is in the retracted state or the extended state. Specifically, the moving mechanism includes a moving slide rail, a connecting slide, a telescopic component of the moving mechanism, and a fixed base. The fixed base is fixed to the ship body and serves as the basis for connecting the corresponding components. The connecting slide is arranged on the fixed base. The moving slide rail is movably mounted on the connecting slide. The connecting slide is the basis for the movably mounted arrangement of the moving rail. One end of the telescopic component of the moving mechanism is connected to the fixed base located inside the ship body, and the other end of the telescopic component of the moving mechanism is connected to the propulsion compartment body. The moving track can move along the connecting slide when the telescopic component of the moving mechanism is extended or retracted. When the telescopic component of the moving mechanism is extended or retracted, it can drive the propulsion compartment body to switch between the direction close to the ship body and the direction away from the ship body. When close to the ship body, it is in the retracted state, and when away from the ship body, it is in the extended state. An engine is provided on the propulsion cabin body, which is connected to the steering propeller via a transmission shaft. A clamping block is provided on the movable track, and a locking mechanism is provided near the movable track. The locking mechanism includes a first clamping hoop, a second clamping hoop, and a telescopic component of the locking mechanism. The locking mechanism is used to lock the movable track. That is, when the propulsion cabin body is in a fully retracted state, the locking mechanism located on the inner side locks the clamping block to achieve the locking of the movable track. When the propulsion cabin body is in a fully pushed-out state, the locking mechanism located on the outer side locks the clamping block of the movable track to achieve the locking of the movable track. This ensures that the propulsion cabin body can be reliably positioned, avoiding shaking or movement, and reliably maintaining its position. When a fleet of multiple ships is moving, the propulsion cabin body located on the unoccupied ship can be pushed horizontally to the outer side of the ship to avoid the water flow of the preceding ship interfering with the steering propeller when forming a fleet, effectively reducing wake accumulation and improving propulsion efficiency. When the propulsion cabin body 1 needs to switch between the retracted state and the pushed-out state, the moving mechanism (pushing mechanism) is composed of the telescopic component of the moving mechanism, the moving slide rail, and the connecting slide seat to form a fast and stable mechanism that can push the propulsion cabin body outboard and can be reliably retracted after use. The locking mechanism securely locks and unlocks, preventing the propulsion compartment from slipping after switching between states. Unlocking facilitates state switching. The fixed base is bolted to the vessel's hull, with pre-recorded screw holes on the vessel for the mounting base, enabling quick installation and easy removal.The rudder propulsion cabin of the present invention is an integrated detachable cabin, which integrates the ship's power unit, transmission device, and propeller steering device in an independent cabin. In the prior art, the rudder propulsion cabin is fixedly installed on the ship body. The present invention can install the rudder propulsion cabin on various barges of the fleet, changing the centralized power to distributed power, thereby greatly improving the maneuverability of the fleet and being able to easily cope with complex water conditions. It is equivalent to a "high-speed train" on the water and can reliably realize power control. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following describes the embodiments with reference to the accompanying drawings to further explain in detail the specific embodiments of the present invention, such as the shapes, structures, mutual positions and connection relationships between the various components involved, the functions and working principles of the various components.

[0030] As attached Figure 1 -Attached Figure 6As shown, the present invention is a propulsion cabin for a multi-ship fleet, comprising a propulsion cabin body 1, a moving mechanism 2, and a locking mechanism 3. The moving mechanism 2 comprises a moving slide rail 4, a connecting slide 5, a moving mechanism telescopic component 6, and a fixed base 7. The fixed base 7 is fixed on the ship body 8, the connecting slide 5 is arranged on the fixed base 7, the moving slide rail 4 is movably mounted on the connecting slide 5, one end of the moving mechanism telescopic component 6 is connected to the fixed base 7 located on the inner side of the ship body 8, and the other end of the moving mechanism telescopic component 6 is connected to the propulsion cabin body 1, an engine 9 is arranged on the propulsion cabin body 1, the engine 9 is connected to the rudder propeller 11 through a transmission shaft 10, a block 12 is arranged on the moving rail 4, and a locking mechanism 3 is arranged near the moving rail 4. The locking mechanism 3 comprises a first clamp 13, a second clamp 14, and a locking mechanism telescopic component 15. When setting up the structure, the propulsion cabin body 1, the moving mechanism 2, and the locking mechanism 3 are made separately. The propulsion cabin body 1 is used to arrange the rudder propeller 11 to realize the propulsion or retreat control of the ship. The moving mechanism 2 is used to realize the folding and pushing out control of the propulsion cabin body 1. The locking mechanism 3 is used to lock the propulsion cabin body 1 by locking the moving track when the propulsion cabin body 1 is in the folded state or the pushed out state. Specifically, the moving mechanism 2 includes a moving slide 4, a connecting slide 5, a moving mechanism telescopic component 6, and a fixed base 7. The fixed base 7 is fixed on the ship body 8 and is the basis for connecting the corresponding components. The connecting slide 5 is arranged on the fixed base 7. The moving slide 4 is movably mounted on the connecting slide 5. The connecting slide 5 is the basis for the movably mounted arrangement of the moving track. One end of the moving mechanism telescopic component 6 is connected to the fixed base 7 located on the inner side of the ship body 8, and the other end of the moving mechanism telescopic component 6 is connected to the propulsion cabin body 1. The moving track can move along the connecting slide when the moving mechanism telescopic component 6 is extended and retracted. When the moving mechanism telescopic component 6 is extended and retracted, it can drive the propulsion cabin body 1 to switch between the direction of approaching the ship body 8 and away from the ship body 8. It is in a retracted state when approaching the ship body 8 and in an extended state when away from the ship body 8. An engine 9 is provided on the propulsion cabin body 1, and the engine 9 is connected to the steering propeller 11 through a transmission shaft 10. A clamping block 12 is provided on the movable track 4, and a locking mechanism 3 is provided near the movable track 4. The locking mechanism 3 includes a first clamping hoop 13, a second clamping hoop 14, and a telescopic component 15 of the locking mechanism. The locking mechanism 3 is used to lock the movable track, that is, when the propulsion cabin body 1 is in a fully retracted state, the locking mechanism 3 located on the inner side locks the clamping block to achieve the locking of the movable track. When the propulsion cabin body 1 is in a fully pushed-out state, the locking mechanism 3 located on the outer side locks the clamping block of the movable track to achieve the locking of the movable track. This ensures that the propulsion cabin body 1 can be reliably positioned to avoid shaking or movement and to reliably maintain its position. When a fleet of multiple ships is moving, the propulsion cabin body 1 located at the outer side of the ship can be pushed horizontally to the outer side of the ship to avoid the water flow of the preceding ship interfering with the steering propeller 11 when forming a fleet, effectively reducing wake accumulation and improving propulsion efficiency.When the propulsion cabin body 1 needs to switch between the stowed state and the pushed-out state, the moving mechanism (push mechanism) is composed of the moving mechanism telescopic component 6, the moving slide rail 4, and the connecting slide 5 to form a fast and stable mechanism, which can push the propulsion cabin body 1 outboard and can be reliably stowed after use. The locking mechanism 3 can be reliably locked and unlocked. After locking, it ensures that the propulsion cabin body 1 will not slip after the state is switched, and after unlocking, it is convenient for state switching. The fixed base 7 and the ship body 8 are connected by bolts. The screw holes required for installing the fixed base 7 are reserved on the ship body 8 to be installed, so that fast installation can be achieved during installation and quick and convenient disassembly. The rudder propulsion cabin of the present invention is an integrated detachable cabin that integrates the ship power unit, transmission device, and propeller steering device into an independent cabin. In the prior art, the rudder propulsion cabin is fixedly installed on the ship body. The present invention can install the rudder propulsion cabin on each barge of the fleet, changing from centralized power to distributed power, thereby greatly improving the maneuverability of the fleet and being able to easily cope with complex water conditions. It is equivalent to a "high-speed train" on the water and reliably realizes power control. The propeller propulsion cabin for a multi-ship fleet described in the present invention has a simple structure, high maneuverability and flexibility of the rudder propeller, and the propulsion cabin body can be pushed out sideways to prevent interference from the preceding ship, reduce wake accumulation, and improve propulsion efficiency.

[0031] The fixed base 7 is parallel to the side 18 of the vessel body 8 and is located at the front of the vessel body 8, near each side 18 of the vessel body. The connecting slide 5 is perpendicular to the side 18 of the vessel body 8 and is located at the front of the vessel body 8, near each side 18 of the vessel body. Each movable track 4 is connected to the propulsion chamber body 1. The movable mechanism telescopic component 6 is perpendicular to the side 18 of the vessel body 8 and is located at the front of the vessel body 8, near each side 18 of the vessel body. In the above structure, the fixed base 7 is fixed to the vessel body 8 by bolts, the connecting slide 5 is fixed to the fixed base 7, and the extension direction of the fixed base 7 and the movable track 4 is set. When the movable mechanism telescopic component 6 is extended or retracted, it drives the movable track 4 to telescope along the direction defined by the connecting slide 5, thereby achieving automatic control of the retraction and extension of the propulsion chamber body 1.

[0032] The fixed base 7 is arranged in parallel with multiple lanes, and the movable track 4 is arranged in parallel with multiple lanes. In order to improve the stability of the structural arrangement, the fixed base 7 is arranged in parallel with multiple lanes, and two lanes can be arranged at a gap, and the movable track 4 is arranged in parallel with multiple lanes, and two lanes can be arranged at a gap.

[0033] One end of the movable track 4 is provided with a block 12 near the end position. In the above structure, each movable slide rail is provided with a block to ensure that locking can be achieved after exiting and retracting.

[0034] The locking mechanism 3's telescopic rod 15 is connected to the movable track 4. One end of the telescopic rod 15 is connected to the first clamp 13, and the other end is connected to the second clamp 14. Both the first and second clamps 13, 14 are flexibly mounted on a positioning rod 19. In this structure, each locking mechanism 3 controls the telescopic rod 15's extension and retraction via a control component, locking and unlocking the first and second clamps 13, 14. One locking mechanism 3 is positioned near one end of the connecting slide 5, and another is positioned near the other end. Limit switches are located on the outer ends of the positioning rods 19 of each locking mechanism 3, and limit switches are located near each end of the connecting slide 5. In this structure, different locking mechanisms are used to lock the block 12 of the movable slide 4 in different states. The movable slide is locked when the propulsion module body 1 is moved to its extended position, and locking can still be achieved when the propulsion module body 1 is moved to its retracted position.

[0035] The telescopic moving mechanism component 6 and the telescopic locking mechanism component 15 are hydraulic cylinders. Each limit switch, the telescopic moving mechanism component 6, and the telescopic locking mechanism component 15 are connected to a control component. The control component can control the telescopic moving mechanism component 6 and the telescopic locking mechanism component 15 to extend and retract, respectively. The control component can also control the propulsion module body to propel in all directions, thus having the dual functions of propelling the ship forward and controlling the ship's movement direction, ensuring normal navigation.

[0036] The present invention also relates to a control method for a propeller propulsion cabin of a multi-ship fleet, which has simple steps, high maneuverability and flexibility of the rudder propeller, and the propulsion cabin body can be pushed out sideways to prevent interference from the preceding ship, reduce wake accumulation, and improve propulsion efficiency. The control steps of the control method for the propeller propulsion cabin of a multi-ship fleet are as follows:

[0037] S1. When the propulsion chamber body is about to move outward, the control component controls the extension of the locking mechanism telescopic component 15 of the inner locking mechanism 3, driving the first clamp 13 and the second clamp 14 of the locking mechanism 3 to move relative to the positioning rod 19 and away from the block 12. When the clamps are released to the limit position, the limit switch is triggered, and the limit switch sends a feedback signal to the control component, which controls the extension of the moving mechanism telescopic component 6. The extension of the moving mechanism telescopic component 6 pushes the sliding rail 4 to move outward along the connecting slide 5, and the propulsion chamber body 1 extends outward;

[0038] S2. When the telescopic member 6 of the moving mechanism extends outward and reaches its limit position, the limit switch is triggered, causing the telescopic member 15 of the locking mechanism of the outer side locking mechanism 3 to retract, driving the first clamp 13 and the second clamp 14 of the locking mechanism 3 to move relative to the positioning rod 19 and approach the block 12, completing the locking of the block 12. The propulsion chamber body 1 completes its outward movement and enters the push-out state, achieving the push-out locking state.

[0039] S3. When the propulsion cabin body 1 is retracted inward, the control component controls the locking mechanism 3 located on the outside to release the lock on the block 12 of the moving track 4, and then the telescopic component 6 of the moving mechanism contracts, driving the moving track 4 to move inward along the connecting slide 5. When the inward contraction reaches the limit position, the limit switch is triggered, and the locking mechanism 3 located on the inside locks the block 12 of the moving track 4. The propulsion cabin body 1 completes the inward movement and enters the contracted state, and is locked after contraction.

[0040] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
