Description

Technical Field

[0001] This application relates to the technical field of ship positioning on water, and more particularly to a vertical positioning device for stable ship positioning on water. Background Technology

[0002] As the core carrier of water transport and operations, the positioning stability of ships directly affects operational safety and efficiency. Traditional anchoring methods suffer from insufficient anchoring force in turbulent waters or soft seabeds, while buoy positioning is easily affected by wind and waves, causing drift. For shallow water operations, although vertical positioning devices can be fixed by inserting piles into the seabed, existing technologies have significant drawbacks:

[0003] First, the simple drive structure of the probe mechanism limits the depth of the pile insertion, resulting in insufficient contact area between the extended support and the bottom, making it prone to tilting in silt or uneven waterbeds. Second, the device lacks an effective water level control mechanism, allowing sludge to easily flow back into the drive components and transmission mechanism through the water inlet during recovery, causing gear jamming. Furthermore, the traditional rigid connection between the water-blocking plate and the outer shell makes it susceptible to structural deformation under wave impact, affecting sealing performance. These problems severely restrict the reliability and service life of the vertical positioning device under complex hydrological conditions.

[0004] To address the aforementioned issues, existing technologies urgently need improvement.

[0005] Application content

[0006] This application aims to at least partially address one of the technical problems in the related art.

[0007] Therefore, the purpose of this application is to propose a vertical positioning device for stable stopping of ships on water. The device uses a drive shaft to drive the probe to the bottom of the water. The limiting base plate and the receiving plate work together to expand the support to increase the contact area. The sealing mechanism adjusts the internal water level to prevent sludge backflow. The water circulation mechanism buffers the impact of waves. This device has the effect of improving positioning stability and extending the service life of the device.

[0008] To achieve the above objectives, this application proposes a vertical positioning device for stable stopping of a ship on water, including a stable positioning component.

The outer wall of the shaft is provided with a receiving plate, a limiting base plate and a probe component in sequence from top to bottom. The limiting base plate is movably disposed between the receiving plate and the probe component. The receiving plate is provided with multiple sets of support members that rotate relative to the end face of the limiting base plate. Each set of support members is provided with a connecting rod on the side near the shaft.

[0010] The stabilizing and positioning assembly also includes a sealing mechanism, an outer extension plate, and a water-passing mechanism;

[0011] The sealing mechanism is disposed within the outer shell to control the internal water level, and the outer extension plate and the water passage mechanism are respectively rotatably disposed on the outer side wall of the outer shell.

[0012] In addition, the vertical positioning device for stable mooring of ships on water, as proposed in the application above, may also have the following additional technical features:

[0013] Specifically, the sealing mechanism includes an inner cover disposed inside the outer shell, a driving component disposed inside the inner cover, a rotating shaft rotatably disposed on one side of the inner cover via a bearing, a transmission component one disposed on one side of the rotating shaft located in the inner cavity of the inner cover, and the transmission component one being meshed with the driving component, and a sealing plate fixedly connected to the other side of the rotating shaft, and multiple sets of through holes arranged in a circular array on the sealing plate.

[0014] Specifically, the water-passing mechanism includes a water-blocking plate and a guide buffer; the water-blocking plate is rotatably disposed on the outer side wall of the outer shell; the guide buffer is disposed on the inner side wall of the outer shell, and the guide buffer is in contact with the water-blocking plate.

[0015] Specifically, the guide buffer includes a hollow shell disposed on the inner side wall of the outer shell, a movable top rod that moves vertically relative to the inner side wall of the outer shell is disposed inside the hollow shell, and a buffer component is sleeved on the outer surface of the movable top rod located on the inner side of the hollow shell.

[0016] Specifically, the driving component includes a second driving component disposed inside the housing, the output end of the second driving component is connected to a second transmission component, and the second transmission component is engaged with the first transmission component.

[0017] The driving component further includes a driving component three disposed inside the inner cover. The output end of the driving component three is provided with a connecting rod, and the end of the connecting rod away from the driving component three is connected to the driving component one.

[0018] Specifically, it also includes a fixed bracket and a storage component. The storage component is mounted on the fixed bracket and includes an outer frame. A sliding plate is movably mounted inside the outer frame. A guide rod is provided on the side of the sliding plate opposite to the fixed bracket. Limiting protrusions are provided on the outer walls of both sides of the outer frame.

[0019] Specifically, the support member includes a flipping rod rotatably mounted on one end face of the receiving plate via a pin, and a limiting block is connected to the end of the flipping rod away from the receiving plate.

[0020] Specifically, a middle partition is provided near the center of the inner cavity of the outer shell, the sealing plate is movably attached to the middle partition, and the middle partition is provided with holes that match the through holes.

[0021] Specifically, the limiting base plate has a protrusion on its end face relative to the receiving plate, and the outer surface of the protrusion abuts against the connecting rod; one end of the connecting rod is rotatably mounted on the support member, and the other end of the connecting rod is slidably mounted on the support member.

[0022] Specifically, the limiting base plate is provided with a ring array of multiple sets of water passage holes, and the limiting base plate is connected to the bottom port of the outer shell through a transition fit.

[0023] The vertical positioning device for stable mooring of ships on water, as described in this application, has the following advantages:

[0024] 1. The probe stabilization mechanism uses a hydraulically driven drive component to push the conical probe component deep into the seabed substrate. At the same time, the mechanical linkage of the connecting rod and the support component causes the support component and the outer extension plate to expand outward, which greatly increases the contact area between the device and the seabed. This effectively resists the impact of water flow and prevents the hull from tilting or drifting, providing the ship with an exceptionally stable ability to stay in turbulent waters.

[0025] 2. During the recycling process, the water flow mechanism opens to form a water flow channel, and some of the water flow can wash away the silt attached to the surface of the probe and the limiting base plate and the water flow hole; at the same time, the sealing mechanism releases the seal to further enhance the water flow to assist in silt removal.

[0026] 3. The sealing mechanism precisely controls the alignment of the through hole on the sealing plate with the hole on the middle partition plate through the driving component. When water enters, it prevents external water from entering the outer shell. When it is recovered, it makes contact and seals, thereby increasing the water flow speed.

[0027] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0038] Embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. Rather, embodiments of this application include all variations, modifications, and equivalents falling within the appended spirit and connotation.

[0039] In existing technologies, ship positioning devices often use anchoring or buoys for mooring and fixation, but these methods suffer from insufficient stability in shallow water or complex seabed conditions. Traditional vertical positioning devices are difficult to adjust the contact area when driven into the seabed due to structural limitations, and are prone to accumulating sludge during retrieval, affecting subsequent use. In a port operation scenario, engineering vessels need to achieve stable mooring on silty seabeds. Conventional positioning piles cause hull swaying due to insufficient driving depth, and the internal transmission components of the device frequently experience jamming due to sludge intrusion.

[0040] To address the aforementioned issues, researchers observed that the contact area between the positioning device and the seabed directly affected stability, and began exploring adjustable support structures. To address the sludge intrusion problem, they attempted to incorporate sealing and flow-guiding structures within the device. By analyzing the impact of water flow on the device, they considered incorporating adjustable flow-guiding components. Ultimately, a comprehensive solution was developed that uses mechanical linkage to achieve support deployment, combined with water level control to prevent sludge intrusion.

[0041] like Figure 1-8 As shown in the embodiment of this application, the vertical positioning device for stable stopping of a ship on water includes a stable positioning component 30. The stable positioning component 30 includes an outer shell 301 and an inner movable probe stabilizing mechanism 303 that probes into the seabed and is fixed.

[0042] The insertion stabilization mechanism 303 includes a drive component 3031 disposed inside the outer casing 301, with the output end of the drive component 3031 connected to a shaft. A receiving plate 3032, a limiting base plate 3033, and an insertion component 3034 are sequentially arranged from top to bottom on the outer wall of the shaft, with the limiting base plate 3033 movably positioned between the receiving plate 3032 and the insertion component 3034. The receiving plate 3032 is rotatably provided with multiple sets of support members 3036 relative to the end face of the limiting base plate 3033, and each set of support members 3036 has a connecting rod 3035 on the side near the shaft.

[0043] It should be noted that the outer shell 301 described in this embodiment adopts a streamlined metal welded shell to support the internal functional components. The drive component 3031 is hydraulically driven. When the drive component 3031 is running, the shaft connected to its output end drives the receiving plate 3032, the limiting base plate 3033, and the probing component 3034 to move. The probing component 3034 is conical and penetrates into the underwater substrate during movement. When the probing component 3034 penetrates into the underwater substrate, the limiting base plate 3033 adheres to the surface of the substrate. At this time, the shaft moves down while the limiting base plate 3033 remains stationary, which pushes the connecting rod 3035 and the support member 3036 to extend outward. The outward extension of the support member 3036, together with the outer extension plate 304, adheres to the underwater substrate, increasing the contact area with the underwater substrate and improving stability.

[0044] The stable positioning component 30 also includes a sealing mechanism 305, an outer extension plate 304, and a water-passing mechanism 302;

[0045] The sealing mechanism 305 is installed inside the outer shell 301 to control the internal water level, and the outer extension plate 304 and the water passage mechanism 302 are respectively rotatably installed on the outer side wall of the outer shell 301.

[0046] It should be noted that the sealing mechanism 305 is used to prevent water from penetrating deep into the interior of the outer casing 301 and affecting the operation of the internal functional components after the outer casing 301 enters the water. The outer extension plate 304, supported by the support member 3036, adheres to the underwater substrate to enhance stability when it flips outward. Simultaneously, the water-passing mechanism 302, through the insertion and stabilization mechanism 303, controls its opening and closing during water entry or exit, achieving self-cleaning by removing attached sludge during water exit.

[0047] In one embodiment of this application, such as Figure 5 As shown, the sealing mechanism 305 includes an inner cover 3051 disposed inside the outer shell 301. A driving member 3052 is provided inside the inner cover 3051. A rotating shaft 3054 is rotatably disposed on one side of the inner cover 3051 via a bearing. A transmission component 3053 is disposed on one side of the rotating shaft 3054 located in the inner cavity of the inner cover 3051. The transmission component 3053 and the driving member 3052 are meshed and connected. A sealing plate 3056 is fixedly connected to the other side of the rotating shaft 3054. Multiple sets of through holes 3055 are arranged in a ring array on the sealing plate 3056.

[0048] It should be noted that the inner cover 3051 described in this embodiment is a protective structure installed inside the outer cover 301, made of metal or engineering plastic, used to isolate the drive component 3052 from the external environment and prevent water intrusion. The transmission component 3053 is a power transmission mechanism, specifically a gear or worm gear structure, which transmits the rotational power of the drive component 3052 to the rotating shaft 3054 through meshing. The sealing plate 3056 is a metal plate with multiple sets of through holes 3055. The sealing plate 3056 is driven to rotate by the rotating shaft 3054, changing the position of the through holes 3055 and thus changing the alignment with the upper part of the intermediate partition 306, achieving water control in the water inlet and outlet states.

[0049] In one embodiment of this application, such as Figure 6 As shown, the water-passing mechanism 302 includes a water-blocking plate 3021 and a guide buffer 3022. The water-blocking plate 3021 is rotatably disposed on the outer side wall of the outer shell 301, and the guide buffer 3022 is disposed on the inner side wall of the outer shell 301, and the guide buffer 3022 abuts against the water-blocking plate 3021.

[0050] It should be noted that a through groove is provided on the outer wall of the outer shell 301. The water-blocking plate 3021 is installed in the through groove on the outer wall of the outer shell 301 by rotating the shaft. The cooperation between the guide buffer 3022 and the receiving plate 3032 causes the receiving plate 3032 to move down, which pushes the guide buffer 3022 open the water-blocking plate 3021 and opens the through groove, allowing water to flow in the lower half of the outer shell 301.

[0051] In one embodiment of this application, such as Figure 7 As shown, the guide buffer 3022 includes a hollow shell 30221 disposed on the inner wall of the outer shell 301. A movable top rod 30222 that is vertically movable relative to the inner wall of the outer shell 301 is disposed inside the hollow shell 30221. A buffer component 30223 is sleeved on the outer surface of the movable top rod 30222 located inside the hollow shell 30221.

[0052] It should be noted that the hollow shell 30221 is a rigid support structure fixed to the inner wall of the outer shell 301. It is made of the same material as the outer shell 301 and provides a moving track and protective space for the movable push rod 30222. Furthermore, the height of the hollow shell 30221 is less than the height of the through groove on the outer wall of the outer shell 301, thus providing sufficient clearance for water flow. The buffer component 30223 is an elastic element sleeved on the outer surface of the movable push rod 30222. It absorbs the impact energy transmitted by the water-blocking plate 3021 and simultaneously drives the water-blocking plate 3021 to reset.

[0053] In one embodiment of this application, such as Figure 5As shown, the drive component 3052 includes a second drive component 30522 disposed inside the housing 301. The output end of the second drive component 30522 is connected to the second transmission component 30521, and the second transmission component 30521 is engaged with the first transmission component 3053.

[0054] The drive component 3052 also includes a drive component 30523 disposed inside the inner cover 3051. The output end of the drive component 30523 is provided with a connecting rod 30524, and the end of the connecting rod 30524 away from the drive component 30523 is connected to the drive component 3031.

[0055] It should be noted that drive component 2 30522 is a stepper motor, while transmission component 2 30521 is a power transmission mechanical mechanism implemented using a gear set. Drive component 2 30522 drives transmission component 1 3053 in the sealing mechanism 305 to rotate through transmission component 2 30521, thereby controlling the opening and closing of the sealing plate 3056. Drive component 3 30523 is an independent power source for controlling drive component 1 3031, and is driven by a hydraulic cylinder. Drive component 3 30523 is connected to drive component 1 3031 through connecting rod 30524 passing through the hollow rotating shaft 3054.

[0056] In one embodiment of this application, such as Figure 1 and Figure 8 As shown, it also includes a fixed bracket 10 and a storage component 20. The storage component 20 is mounted on the fixed bracket 10. The storage component 20 includes an outer frame 201. A sliding plate 202 is movably mounted on the inner side of the outer frame 201. A guide rod 203 is provided on the side of the sliding plate 202 away from the fixed bracket 10. Limiting protrusions 204 are provided on the outer walls of both sides of the outer frame 201.

[0057] It should be noted that the fixed bracket 10 and the supporting structural components used to support and fix the storage assembly 20 are installed on the ship deck by welding or bolting. The storage assembly 20 adopts a sliding frame structure. The ship is equipped with hoisting equipment, which is connected to the sliding plate 202 in the storage assembly 20 via a chain. The guide rod 203 connected below the sliding plate 202 is connected to the outer shell 301. The outer frame 201 is provided with a sliding groove that matches the limiting protrusion 204. The limiting protrusion 204 restricts the movement path of the sliding plate 202 in the outer frame 201.

[0058] In one embodiment of this application, such as Figure 4 As shown, the support member 3036 includes a flipping rod 30361 that is rotatably mounted on one end face of the receiving plate 3032 via a pin. The end of the flipping rod 30361 away from the receiving plate 3032 is connected to the limiting block 30362.

[0059] It should be noted that the flipping rod 30361 refers to a rod-shaped structure that changes the support angle through rotational movement. Specifically, it can be made by stamping metal sheet and then assembling a pin. The limiting block 30362 refers to a block-shaped structure used to constrain the reset position of the flipping rod 30361. Specifically, it can be fixed to the end of the flipping rod 30361 by welding or bolting.

[0060] Furthermore, a positioning groove is provided on the limiting base plate 3033 for limiting the limiting block 30362 during the reset process.

[0061] In one embodiment of this application, such as Figure 2 As shown, a middle partition plate 306 is provided near the middle of the inner cavity of the outer shell 301, and a sealing plate 3056 is movably attached to the middle partition plate 306. The middle partition plate 306 is provided with a hole that matches the through hole 3055.

[0062] It should be noted that the intermediate partition 306 is used to divide the inner cavity of the outer shell 301 into two parts. The sealing plate 3056 is attached to and rotated on the intermediate partition 306. During the water entry process, the hole and the through hole 3055 are misaligned to achieve water blocking and ensure sealing.

[0063] In one embodiment of this application, such as Figure 3 As shown, the limiting base plate 3033 has a protrusion on the end face of the receiving plate 3032. The outer surface of the protrusion abuts against the connecting rod 3035. One end of the connecting rod 3035 is rotatably mounted on the support member 3036, and the other end of the connecting rod 3035 is slidably mounted on the support member 3036.

[0064] It should be noted that the protrusion refers to the raised structure provided on the end face of the limiting base plate 3033, which can be implemented using a metal block with a trapezoidal or arc-shaped cross-section, and its outer surface forms a contact surface with the connecting rod 3035. When the shaft connected to the output end of the driving component 3031 moves relative to each other, the protrusion abuts against the connecting rod 3035 and pushes the support member 3036 outward.

[0065] Furthermore, the connecting rod 3035 adopts a double connecting rod structure, and the connection of the connecting rod 3035 is achieved through a pin with a spiral spring. One end of the connecting rod 3035 is rotated, while the other end is slidably connected. The connecting rod 3035 and the support member 3036 achieve linear movement through the cooperation of a sliding groove and a slider, which can be a dovetail groove or a T-slot structure.

[0066] In one embodiment of this application, such as Figure 4 As shown, the limiting base plate 3033 has a ring array of multiple sets of water passage holes 3037, and the limiting base plate 3033 is connected to the bottom port of the outer shell 301 through a transition fit.

[0067] It should be noted that the water passage 3037 refers to a channel penetrating the thickness direction of the limiting base plate 3033. Specifically, it can be implemented using a circular, elliptical, or irregularly shaped hole structure, with a diameter ranging from, for example, 5 to 20 millimeters. This feature allows water flow during the device's water introduction process, reducing the impact resistance of water pressure on the limiting base plate 3033, and simultaneously promoting sludge discharge from the channel during recycling.

[0068] Specifically, the steps for using the vertical positioning device for stable mooring of ships on water are as follows:

[0069] Positioning below: The fixed bracket 10 is installed on the hull of the ship. The sliding plate 202 is driven by the hoisting equipment on the ship to slide within the outer frame 201 to adjust the height. The stable positioning component 30 is connected through the guide rod 203. The stable positioning component 30 is then lowered into the water and embedded in the bottom substrate to enhance the stability of the ship when it is docked.

[0070] Waterproof sealing: After the outer casing 301 is submerged in water, the sealing mechanism 305 immediately activates. The second driving component 30522 in the driving component 3052 operates, driving the rotating shaft 3054 to rotate through the meshing transmission component 30521 and the first transmission component 3053. This causes the sealing plate 3056 to rotate, misaligning its through hole 3055 with the hole on the intermediate partition plate 306, cutting off the passage between the inner cavity of the outer casing 301 and the external water body, and preventing water from entering the internal driving components.

[0071] Penetrating the underwater substrate: The conical design of the penetrating component 3034 facilitates penetration into the underwater substrate. At the same time, the limiting base plate 3033 is relatively slowed down due to resistance during the downward movement of the shaft, and eventually stops after penetrating a certain distance into the substrate, serving as the pressure-bearing foundation for the subsequent deployment of the support component 3036.

[0072] Deploying the support: Drive component 3031 continues to push the shaft downwards. Since the limiting base plate 3033 has abutted against the substrate, the relative movement between the shaft and the receiving plate 3032 forces the connecting rod 3035 to move. One end of the connecting rod 3035 slides while the other end rotates, transmitting force to the support component 3036. At the same time, the protrusion on the limiting base plate 3033 pushes the flipping rod 30361 to flip outwards and unfold, disengaging the end limiting block 30362 from the positioning groove of the limiting base plate 3033. Simultaneously, the flipping rod 30361 pushes the outer extension plate 304 to unfold accordingly. The outer extension plate 304 extends into the substrate, greatly increasing the contact area between the device and the seabed, effectively resisting water flow impact and preventing the hull from tilting.

[0073] As the probe 3034 moves downward, the receiving plate 3032 moves downward as well. The receiving plate 3032 abuts against the guide buffer 3022, and the movable push rod 30222 is forced to push the water blocking plate 3021 to flip outward, opening the through groove on the side wall of the outer shell 301. At this time, the water flow is limited in the lower half of the outer shell 301, which helps to balance the internal and external pressures and allows some water flow to flush away loose mud and sand that may accumulate near the limiting bottom plate 3033, reducing resistance for subsequent recycling.

[0074] Recovery and Self-Cleaning: Drive component 3031 flips, pulling the shaft and receiving plate 3032 upwards. Connecting rod 3035 loosens accordingly, and support component 3036 retracts inwards under its own gravity, detaching from the underwater substrate. During the upward movement of the shaft, after the probe component 3034 detaches from the underwater substrate, drive component 30523 runs repeatedly three times. During operation, drive component 30523 pushes open the water-blocking plate 3021, and water flows through the through groove on the outer wall of the outer shell 301 to flush the water holes 3037 on the probe component 3034 and the limiting base plate 3033, and opens and flushes the water-blocking plate 3021, removing some of the entrained water and mud.

[0075] During the water discharge process, the second drive component 30522 operates again, driving the sealing plate 3056 to rotate, aligning the through hole 3055 with the hole in the intermediate partition plate 306, releasing the seal, and increasing the water flow speed to facilitate flushing and sludge removal. The sliding plate 202 of the receiving component 20 is lifted, and the entire stable positioning component 30 is pulled back to the hull until it is fully retracted via the guide rod 203. As the receiving plate 3032 rises, the pressure on the guide buffer component 3022 is released. Under the elastic force and gravity of the buffer component 30223, the movable top rod 30222 retracts, the water-blocking plate 3021 closes, sealing the through groove and preventing debris from entering the shell.

[0076] In summary, the vertical positioning device for stable water positioning of ships in this application embodiment drives the probe to the bottom of the water through a drive shaft, the limiting bottom plate and the receiving plate work together to expand the support to increase the contact area, the sealing mechanism adjusts the internal water level to prevent sludge backflow, and the water passage mechanism buffers the impact of waves, which has the effect of improving positioning stability and extending the service life of the device.
