Description

Technical Field

[0001] This utility model relates to the field of waterborne measurement equipment technology, and in particular to a side-lifting type floating dock device for unmanned measurement vessels. Background Technology

[0002] In waterway dredging and harbor basin silt removal projects, to ensure construction quality, it is often necessary to remeasure the water depth at intervals. Currently, unmanned surface vessel (USV) depth measurement technology is relatively mature; therefore, using USVs for depth measurement and water sample collection can significantly reduce workload. However, USVs have limited power and data processing capabilities. After a period of depth measurement and sample collection, the USV needs to be retrieved. This is because after retrieval, manual maintenance of the USV's power system is required, including battery replacement, data processing, and sample collection.

[0003] Traditional unmanned surface vessel (USV) recovery technologies typically employ shore-based recovery methods. This involves maneuvering the USV to shallow waters near the shore and manually pulling it back. However, USVs are susceptible to drifting or collisions due to wind, waves, and currents, making recovery difficult. Furthermore, manual labor is labor-intensive and inefficient, unsuitable for long-term, large-scale operations. Recovery from dredging vessels is less common due to the significant safety risks associated with the distance between the vessel's side and the water surface. While dock recovery is an option, traditional floating docks, primarily used for large vessel repair, are bulky, have limited functionality, and are unsuitable for smaller USVs, limiting their flexibility and applicability to various waterway dredging and harbor basin cleanup projects.

[0004] Therefore, in order to meet the need for rapid recovery of unmanned survey vessels in dredging, silt removal and other engineering projects with high frequency and multiple scenarios, designing a special recovery device that is safe, reliable, economical and convenient and adapted to the characteristics of unmanned vessels has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a side-lifting type floating dock device for measuring unmanned vessels.

[0006] This utility model is achieved through the following technical solution: A side-lifting type floating dock device for measuring unmanned surface vessels includes a hoisting mechanism and a basket mechanism located on one side of the hull of a dredging vessel. The hoisting mechanism includes a lifting assembly and a fixed frame. The lifting assembly enables the measuring unmanned surface vessel above the fixed frame to reciprocate longitudinally. The basket mechanism includes a accommodating basket connected above the fixed frame. One side of the accommodating basket has an opening for the measuring unmanned surface vessel to enter or leave the basket mechanism.

[0007] According to the above technical solution, preferably, the lifting assembly includes a crane fixedly connected to the deck of the dredging vessel near the ship's side, a boom set on the top of the crane, an electric hoist set on the outer end of the boom, a main lifting rope connected to the electric hoist, a hook set at the bottom of the main lifting rope, and branch lifting ropes suspended on the hook. Multiple branch lifting ropes are provided for connecting to the accommodating basket and driving the basket mechanism to move back and forth longitudinally.

[0008] According to the above technical solution, preferably, four branch ropes of equal length are suspended on the hook, and the ends of each branch rope are connected to the accommodating basket through a hanging ring.

[0009] According to the above technical solution, preferably, the lifting assembly further includes a side support frame fixedly connected to the side of the dredging construction vessel, and the fixed frame is slidably connected to the side support frame.

[0010] According to the above technical solution, preferably, the side support frame includes a connecting plate fixedly connected to the side of the dredging construction vessel, a lifting rod fixedly connected to the connecting plate, a sliding sleeve slidably connected to the lifting rod, and a fixed crossbar fixedly connected to the sliding sleeve. The lifting rod is vertically arranged along the longitudinal direction, and the fixed crossbar is connected to the fixed frame to support the fixed frame.

[0011] According to the above technical solution, preferably, the accommodating basket includes a float fixedly connected to the top of the fixed frame, side baffles disposed on both sides of the float, and a buffer plate located on one side of the float.

[0012] According to the above technical solution, preferably, the surface of the float is provided with multiple drainage holes, so that water can be discharged from the drainage holes at the bottom when the accommodating basket is lifted upwards out of the water. Preferably, the drainage holes are designed as rectangular through holes, and multiple rubber guide wheels are installed inside the drainage holes, with the rubber guide wheels arranged along the direction in which the unmanned measuring vessel enters or exits.

[0013] According to the above technical solution, preferably, the surface of the buffer plate is provided with multiple sets of water-permeable holes, which are used to discharge water waves aroused when the unmanned measuring vessel enters the accommodating basket.

[0014] The beneficial effects of this utility model are: This utility model deploys the hoisting mechanism and basket mechanism on the dredging construction vessel, enabling convenient deployment and retrieval of the unmanned vessel without the need to travel back and forth to the shore. The vessel can replace batteries, process data, and collect samples within the construction water area. At the same time, it eliminates the need for personnel to go into the water or manually pull it from the shore, saving manpower and improving the efficiency of unmanned vessel retrieval and launch. The unmanned boat can drive directly into the basket and be lifted. The whole process is continuous and smooth, which shortens the operation time. In addition, the basket contains and fixes the unmanned boat, preventing collisions or overturning during the lifting or lowering process. It also avoids safety risks caused by wind, waves, water flow and other factors. The hoisting and basket mechanisms occupy little space and can be flexibly deployed on dredging vessels. They can change position as the vessel moves, enabling measurement and monitoring operations to be carried out around the construction area. This shortens the travel distance of the unmanned measurement vessel to and from the target area, expands the scope of waterborne measurement operations, and allows operation in different waters such as channel dredging and port basin dredging, thus broadening the application scenarios.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] In the description of the utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0025] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0026] Example 1: As shown in the figure, the present invention includes a hoisting mechanism and a basket mechanism located on one side of the hull of the dredging construction vessel. The hoisting mechanism includes a lifting component and a fixed frame 27. The lifting component enables the measuring unmanned vessel 10 above the fixed frame 27 to move longitudinally back and forth. The basket mechanism includes a accommodating basket connected above the fixed frame 27. One side of the accommodating basket is open for the measuring unmanned vessel 10 to enter or leave the basket mechanism.

[0027] The lifting assembly includes a crane 50 fixedly connected to the deck of the dredging vessel near the ship's side, a boom 51 set on top of the crane 50, an electric hoist 56 set on the outer end of the boom 51, a main hoisting rope 52 connected to the electric hoist 56, a hook 53 set at the bottom of the main hoisting rope 52, and a branch hoisting rope 55 suspended on the hook 53.

[0028] Specifically, in this example, a crane 50 is welded to the side of the dredging vessel's deck. A boom 51 is mounted on top of the crane 50, facing outwards from the hull. An electric hoist 56 is installed on the outermost part of the boom 51, near the waterline, to control the lifting and lowering of the hopper mechanism. The main lifting rope 52 is positioned on the outer side of the hull to facilitate lifting operations on the water surface. A hook 53 is connected to the bottom of the main lifting rope 52, and four branch ropes 55 are suspended from the hook 53. The ends of each branch rope 55 are connected to the hopper via a hanging ring 21. The four branch ropes 55 are of equal length, ensuring the hopper mechanism remains as horizontal as possible and maintaining the stability of the unmanned measuring vessel 10 within the hopper mechanism.

[0029] The lifting assembly also includes a side support frame fixedly connected to the side of the dredging vessel, with the fixed frame 27 slidably connected to the side support frame. The side support frame includes a connecting plate 12 fixedly connected to the side of the dredging vessel, a lifting rod 11 fixedly connected to the connecting plate 12, a sliding sleeve slidably connected to the lifting rod 11, and a fixed crossbar 18 fixedly connected to the sliding sleeve. The lifting rod 11 is vertically arranged along the longitudinal direction, and the fixed crossbar 18 is connected to the fixed frame 27 to support the fixed frame 27.

[0030] Specifically, in this example, four connecting plates 12 are horizontally installed on the side of the dredging vessel by welding. The connecting plates 12 are made of metal, and each of the four connecting plates 12 has a mounting hole 13 at one end of the vessel. Lifting rods 11 are connected to the connecting plates 12 via the mounting holes 13 using fixing screws. One lifting rod 11 is installed between each pair of connecting plates 12, resulting in two vertically installed lifting rods 11. The lifting rods 11 are made of metal, allowing the basket mechanism to move vertically up and down along the lifting rods 11. The sliding sleeve includes a mounting frame 16 and sliding guide wheels 17. A mounting frame 16 is installed on the outer side of each of the two lifting rods 11. The mounting frame 16 is a rectangular metal frame, with sliding guide wheels 17 installed inside the four corners of the frame. Two grooves are provided on both sides of the lifting rod 11, allowing the sliding guide wheels 17 to roll along the grooves. In this example, it is preferred, but not limited to, that four sliding guide wheels 17 are provided in the mounting frame 16, of which two guide wheels slide along the outer groove of the lifting rod 11 and two guide wheels slide along the inner groove of the lifting rod 11, so that the basket mechanism can slide up and down along the lifting rod 11 relatively smoothly.

[0031] Meanwhile, the accommodating basket includes a float 26 fixedly connected to the top of the fixed frame 27, side baffles 22 opposite to both sides of the float 26, and a buffer plate 24 located on one side of the float 26. The float 26 is made of hollow plastic, and the fixed frame 27 is a metal frame. The bottom is connected to the fixed frame 27 by adhesive bonding, so that the hoisting mechanism and the basket mechanism form a whole. In this example, it is preferred, but not limited to, that the upper surface of the float 26 is designed as an inverted triangle, in order to adapt to the wedge-shaped interface at the bottom of the measurement unmanned vessel 10 and maintain the stability of the measurement unmanned vessel 10.

[0032] Preferably, the surface of the float 26 is provided with multiple drainage holes 28, which allow water to drain out from the bottom of the accommodating basket when it is lifted out of the water. The drainage holes 28 are preferably designed as rectangular through holes, and multiple rubber guide wheels 23 are installed inside each drainage hole 28. The rubber guide wheels 23 are arranged along the direction in which the unmanned measuring vessel 10 enters or leaves the basket mechanism, and are arranged in a straight line within each drainage hole 28. This facilitates smoother movement of the unmanned measuring vessel 10 when it enters or leaves the basket mechanism, reduces friction between the bottom of the unmanned measuring vessel 10 and the float 26, and also prevents the unmanned vessel from being unable to move on the float 26 due to excessive friction when leaving it.

[0033] Two side baffles 22 are provided on both sides of the float 26. The distance between the side baffles 22 is slightly larger than the width of the unmanned measuring vessel 10, so that when the unmanned measuring vessel 10 is swayed from side to side under the action of external force, it is not easy to fall off the float 26. In this example, the ends of each branch hoisting rope 55 are connected to the upper part of the side baffle 22 through the hanging ring 21 to realize the hoisting and lowering of the basket mechanism.

[0034] A buffer plate 24, made of foam plastic, is bonded to the other side of the float 26. Its purpose is to provide cushioning for the unmanned surface vessel 10 when it enters the float 26, preventing it from being thrown off the float 26 due to inertia. Simultaneously, multiple sets of water-permeable holes 25 are formed on the surface of the buffer plate 24. When the unmanned surface vessel 10 enters the accommodating basket, the water waves generated forward can be discharged through the water-permeable holes 25 into the basket mechanism, improving the lateral drainage effect of the basket mechanism and reducing its swaying.

[0035] Example 2: Based on Example 1 above, during dredging operations, when it is necessary to conduct water depth measurements and water quality sampling in the waters near the dredging vessel, it is necessary to lower the unmanned surveying vessel from the dredging vessel to the water surface. The floating dock device provided in this application is used for lowering the unmanned surveying vessel, and the implementation method is as follows: S11: The suspended platform mechanism is placed at an appropriate height: by operating the electric hoist, the main hoisting rope and hook are lifted to raise the suspended platform mechanism to a position that is almost horizontal with the ship's deck; S12: Place the surveying unmanned vessel into the basket mechanism: The operator places the surveying unmanned vessel on the float in the basket mechanism from the deck of the dredging construction vessel. S13: Height of the lower basket mechanism to the water surface: By operating the electric hoist, the main hoisting rope and hook are lowered to lower the basket mechanism to the water surface. Under the action of buoyancy, the float can float on the water surface. Affected by the waves on the water surface, the basket mechanism will sway. The side baffle will act as a stop to prevent the unmanned boat from falling off the side of the basket mechanism. S14: Remote-controlled measurement unmanned vessel departs from the basket mechanism: The surveyor remotely controls the unmanned vessel to depart from the floating body and sail towards the side of the floating body without the baffle. After receiving the navigation maintenance instruction, the unmanned vessel departs from the basket mechanism and carries out water depth measurement, water quality sampling and other work in the surrounding waters.

[0036] Example 3: Based on Example 1 above, when the unmanned surveying vessel completes water depth measurement and water quality sampling in the surrounding waters, or needs to replace batteries or collect data, the unmanned surveying vessel in the construction area needs to be retrieved to the deck of the dredging construction vessel. The floating dock device provided in this application is used for the retrieval of the unmanned surveying vessel, and the implementation method is as follows: S21: The basket mechanism is placed at an appropriate height: by operating the electric hoist, the main hoisting rope and hook are lowered to the water surface position. Under the action of buoyancy, the lower half of the float is below the water surface, and the top of the buffer plate is exposed above the water surface. S22: Measurement Unmanned Vessel Enters the Basket Mechanism: The measurement personnel remotely control the measurement unmanned vessel to enter the floating body from the side without baffles; after receiving the return command, the measurement unmanned vessel smoothly enters the basket mechanism under the support of the rubber guide wheels, and slows down and stops under the blocking effect of the buffer plate. The water waves stirred up are discharged through the water permeable holes, reducing the shaking of the basket mechanism. S23: Raise the suspended platform mechanism to the height of the construction vessel's side: By operating the electric hoist, the suspended platform mechanism is lifted off the water surface, and the water is discharged through the drainage holes set on the float and the water-permeable holes set on the buffer plate; S24: Remove the measurement drone from the basket mechanism: Using the electric hoist, raise the basket mechanism to a position almost horizontal with the ship's deck; the operator removes the measurement drone from the basket mechanism to replace the battery, collect data, collect samples, etc.; if measurement work needs to be performed again, repeat the measurement drone lowering steps of Example 2.

[0037] In summary, this application provides a safe, convenient, efficient, and highly adaptable method for launching and recovering unmanned surveying vessels, avoiding the shortcomings of manual pulling or traditional docks. It also facilitates onboard maintenance and data processing, thereby improving the overall efficiency and reliability of unmanned vessel applications in dredging operations.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
