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] Usually, the propeller or thruster of a ship is installed in the hull at the stern of the ship. Some small ships also install the thruster on the deck. For a fleet of multiple ships connected head to tail, in order to avoid the impact of the propeller wake on the following ships, usually only the propeller is installed at the stern of the last ship. Due to the small number of propellers and limited propulsion power, it is difficult to increase the speed. Although the fleet has the advantages of large transportation volume, small resistance, low transportation cost, flexible transportation, and can improve the navigation rate of ships, it has low speed, poor safety and operability due to the centralized power propulsion method. It is difficult to dispatch in narrow waterways, difficult to turn, and easy to interfere with the normal navigation order of the waterway. Among the existing propulsion methods such as propellers, jet pumps, and rudder propellers, propeller propulsion is currently the most commonly used propulsion method. It has a simple structure and light weight and can be used for most ships, but at high speeds, due to the large friction and resistance, there will be large noise and vibration. The jet pump has the advantages of fast response and high ship speed, and is suitable for high-speed ships, but its structure is complex and the maintenance cost is high. The rudder propulsion structure is similar to a rudder, which can control the direction of the ship and generate thrust. It is suitable for ships that need to make frequent turns and operate in narrow waters, but its propulsion efficiency is low. Existing propulsion methods are usually installed inside the hull at the stern of the ship and can only be used in specified positions. When the propeller is installed inside the hull at the stern of each ship in the fleet, theoretically, the centralized power can be changed to distributed power to improve the fleet's operability and increase its speed. However, in reality, since the rudder propulsion cabin is installed on the deck, it is inevitable that wake accumulation will occur, reducing the propulsion efficiency.

[0003] In the prior art, there is a technology named "a ship propeller and its ship" and the publication (announcement) number is "CN207943151U", which provides a ship propeller, through a slide plate, two rotatable tilting mechanisms, a set of bevel gear sets connected to a motor, and the reciprocating blades tilt at a specific position to provide thrust for the ship. It has high propulsion efficiency and is simple to manufacture. Ships, warships, and submarines can use internal combustion engines, nuclear power, batteries, or manpower, with low noise and no pollution. However, this technology does not involve 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 with 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.

[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 seat, a telescopic component of the moving mechanism, and a fixed base. The fixed base is fixed on the ship body, the connecting slide seat is arranged on the fixed base, the moving slide rail is movably mounted on the connecting slide seat, 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 arranged at the front of the ship body close to 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 sides of the ship body 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 sides of each side of the ship body.

[0010] The fixed base is arranged in multiple parallel paths, and the movable track is arranged in multiple parallel paths.

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

[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 arranged near one end of the connecting slide, another locking mechanism is arranged near the other end of the connecting slide, a limit switch is arranged at the outer end of the positioning rod of each locking mechanism, and a limit switch is arranged 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 with 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 cabin body is about to move outward, the control component controls the locking mechanism telescopic component of the locking mechanism located on the inner side to extend, driving the first clamp and the second clamp of the locking mechanism to move relative to the positioning rod and away from the block. When the clamp is loosened to the limit position, the limit switch is triggered, and the limit switch feeds back a signal to the control component. The control component controls the telescopic component of the moving mechanism to extend, and the telescopic component of the moving mechanism extends to push the sliding rail to move outward along the connecting slide seat, and the propulsion cabin body extends outward;

[0017] S2. When the telescopic part of the moving mechanism extends outward to the limit position, the limit switch is triggered, and the telescopic part of the locking mechanism of the side locking mechanism located on the outside is contracted, driving the first clamp and the second clamp of the locking mechanism to move relative to the positioning rod and approach the block, completing the locking of the block, and the propulsion cabin body completes the outward movement and enters the push-out state, and realizes the locking after the push-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 it contracts inward to 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 cabin of the multi-ship fleet described in the present invention is structured by separately making a propulsion cabin body, a moving mechanism, and a locking mechanism. The propulsion cabin body is used to arrange the steering paddle to realize the propulsion or retreat control of the ship. The moving mechanism is used to realize the folding and pushing out control of the propulsion cabin body. The locking mechanism is used to lock the propulsion cabin body by locking the moving track when the propulsion cabin body is in the folded state or the pushed out state. Specifically, the moving mechanism includes a moving slide rail, a connecting slide seat, a telescopic component of the moving mechanism, and a fixed base. The fixed base is fixed on the ship body and is the basis for connecting the corresponding components. The connecting slide seat is arranged on the fixed base. The moving slide rail is movably mounted on the connecting slide seat. The connecting slide seat is the basis for movably mounting the moving track. 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. The moving track can move along the connecting slide seat when the telescopic component of the moving mechanism is extended. When the telescopic component of the moving mechanism is extended, the moving track can drive the propulsion cabin body to switch between the direction close to the ship body and the direction away from the ship body. When it is close to the ship body, it is in the folded state, and when it is away from the ship body, it is in the pushed out state. An engine is arranged on the propulsion cabin body, and the engine is connected to the steering 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 includes a first clamp, a second clamp, and a telescopic component of the locking mechanism. The locking mechanism is used to lock the moving track, that is, when the propulsion cabin body is in a fully retracted state, the locking mechanism located on the inner side locks the card block to achieve the locking of the moving track. When the propulsion cabin body is in a fully pushed out state, the locking mechanism located on the outer side locks the card block of the moving track to achieve the locking of the moving track, so that the propulsion cabin body can be reliably positioned to avoid shaking or swaying, and the position can be reliably maintained. When a fleet formed by multiple ships is moving, the propulsion cabin body located in the unshipped ship can be pushed horizontally to the outer side of the ship to avoid the water flow of the front ship interfering with the steering propeller when forming a fleet, effectively reducing the accumulation of wake and improving the propulsion efficiency. When the propulsion cabin body 1 needs to switch between the retracted state and the pushed out state, the moving mechanism (push mechanism) is composed of a telescopic component of the moving mechanism, a moving slide rail, and a connecting slide seat to form a fast and stable mechanism, which can push the propulsion cabin body outboard and can be reliably retracted after use. The locking mechanism can be locked and unlocked reliably. After locking, it is ensured that the propulsion cabin body will not slip after the state is switched. After unlocking, it is easy to switch the state. The fixed base and the ship body are connected by bolts. The screw holes required for installing the fixed base are reserved on the ship body to be installed, which can achieve quick installation and convenient and quick disassembly.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

[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 seat 5, a moving mechanism telescopic component 6, and a fixed base 7. The fixed base 7 is fixed on a ship body 8, the connecting slide seat 5 is arranged on the fixed base 7, the moving slide rail 4 is movably mounted on the connecting slide seat 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, and the engine 9 is connected to a rudder propeller 11 through a transmission shaft 10, a block 12 is arranged on the moving track 4, and a locking mechanism 3 is arranged near the moving track 4, and 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, a propulsion cabin body 1, a moving mechanism 2, and a 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 mobile mechanism 2 includes a mobile slide rail 4, a connecting slide 5, a mobile 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 mobile slide rail 4 is movably mounted on the connecting slide 5. The connecting slide 5 is the basis for the movably mounted arrangement of the mobile rail. One end of the mobile 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 mobile mechanism telescopic component 6 is connected to the propulsion cabin body 1. The mobile rail can move along the connecting slide when the mobile mechanism telescopic component 6 is telescoped. When the mobile mechanism telescopic component 6 is telescoped, 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. When it is close to the ship body 8, it is in a retracted state, and when it is away from the ship body 8, it is in a pushed-out state. The propulsion cabin body 1 is provided with an engine 9, and the engine 9 is connected to the steering propeller 11 through a transmission shaft 10. A card block 12 is provided on the moving track 4, and a locking mechanism 3 is provided near the moving track 4. The locking mechanism 3 includes a first clamp 13, a second clamp 14, and a locking mechanism telescopic component 15. The locking mechanism 3 is used to lock the moving 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 card block to achieve the locking of the moving 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 card block of the moving track to achieve the locking of the moving track, so that the propulsion cabin body 1 can be reliably positioned to avoid shaking or movement, and reliably maintain the position. When a fleet formed by multiple ships is moving, the propulsion cabin body 1 located at the unshipped ship can be pushed horizontally to the outer side of the ship to avoid the water flow of the front ship interfering with the steering propeller 11 when forming a fleet, effectively reducing the accumulation of wake and improving the 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 seat 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 is ensured that the propulsion cabin body 1 will not slip after the state is switched, and it is convenient to switch the state after unlocking. The fixed base 7 and the ship body 8 are connected by bolts, and 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 disassembly is also convenient and fast. The rudder propulsion cabin of the present invention is an integrated detachable cabin, which integrates the ship power device, transmission device, and propeller steering device in an independent cabin, while the prior art is to fix the rudder propulsion cabin on the ship body. The present invention can install the rudder propulsion cabin on each barge of the fleet, changing the centralized power to distributed power, thereby greatly improving the maneuverability of the fleet, and can easily face complex water conditions, which is equivalent to a "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 ship body side 18 of the ship body 8, and the fixed base 7 is arranged at the front of the ship body 8 near the ship body side 18 on each side. The connecting slide 5 is arranged perpendicular to the ship body side 18 of the ship body 8, and the connecting slide 5 is arranged at the front of the ship body 8 near the ship body side 18 on each side, and each movable track 4 is connected to the propulsion cabin body 1. The moving mechanism telescopic component 6 is perpendicular to the ship body side 18 of the ship body 8, and the moving mechanism telescopic component 6 is arranged at the front of the ship body 8 near the ship body side 18 on each side. In the above structure, the fixed base 7 is fixed to the ship 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 moving mechanism telescopic component 6 is extended, it drives the movable track 4 to telescopically move along the direction defined by the connecting slide 5, so as to realize the automatic control of the folding and pushing out of the propulsion cabin body 1.

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

[0033] A clamping block 12 is arranged near the end position of one end of the moving track 4. In the above structure, a clamping block is arranged on each moving slide rail to ensure that locking can be achieved after withdrawal and folding.

[0034] The locking mechanism telescopic rod 15 of the locking mechanism 3 is connected to the movable track 4, one end of the locking mechanism telescopic rod 15 is connected to the first hoop 13, and the other end of the locking mechanism telescopic rod 15 is connected to the second hoop 14. The first hoop 13 and the second hoop 14 are movably mounted on the positioning rod 19. In the above structure, each locking mechanism 3 controls the telescopic rod 15 of the locking mechanism to be extended and retracted by the control component to achieve the locking and unlocking of the first hoop 13 and the second hoop 14. A locking mechanism 3 is arranged near one end of the connecting slide 5, and another locking mechanism 3 is arranged near the other end of the connecting slide 5. The outer end of the positioning rod 19 of each locking mechanism 3 is respectively provided with a limit switch, and the connecting slide 5 is respectively provided with a limit switch near each end. In the above structure, different locking mechanisms are used to lock the block 12 of the movable slider 4 in different states. When the propulsion cabin body 1 moves to the extreme position of the push-out state, the movable slider is locked, and when the propulsion cabin body 1 moves to the extreme position of the stowed state, the locking can still be achieved.

[0035] The moving mechanism telescopic component 6 and the locking mechanism telescopic component 15 are hydraulic cylinders, and each limit switch, the moving mechanism telescopic component 6 and the locking mechanism telescopic component 15 are connected to the control component respectively. The control component can control the moving mechanism telescopic component 6 and the locking mechanism telescopic component 15 to telescope respectively, and the control component can also control the propulsion cabin body to propel in all directions, having the dual functions of propelling the ship forward and manipulating the direction of movement of the ship to ensure normal navigation.

[0036] The present invention also relates to a control method for a propeller propulsion cabin of a multi-ship fleet with 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 cabin body is about to move outward, the control component controls the locking mechanism telescopic component 15 of the locking mechanism 3 located on the inner side to extend, 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 clamp is loosened to the limit position, the limit switch is triggered, and the limit switch feeds back a signal to the control component. The control component controls the moving mechanism telescopic component 6 to extend, and the moving mechanism telescopic component 6 extends to push the sliding rail 4 to move outward along the connecting slide 5, and the propulsion cabin body 1 extends outward;

[0038] S2. When the telescopic part 6 of the moving mechanism extends outward to the limit position, the limit switch is triggered, and the telescopic part 15 of the locking mechanism of the side locking mechanism 3 located on the outside contracts, 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, and the propulsion cabin body 1 completes the outward movement, enters the push-out state, and realizes the locking after the push-out;

[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.
