Description

Technical Field

[0001] The present application relates to the technical field of deployment and recovery of marine survey equipment and instruments, and in particular to a shipborne simple anti-sway device and a design method thereof. Background Art

[0002] With the growing demand for marine resource development, scientific exploration and marine safety in my country, more and more scientific research vessels and modified fishing vessels are being put into marine survey operations. These vessels conduct surveys by fixed-point and towing methods, and the operation process relies on some supporting equipment on the rear deck, such as winches, A-frames, folding arm crane systems and auxiliary boats.

[0003] In the release operation, the winch is used to retract and release the equipment, and the A-frame is used to swing the equipment out of the ship, forming a simple release mode. In the recovery operation, the winch is used to pull the equipment, and the A-frame is used to swing the equipment back into the ship, forming a simple recovery mode. This simple mode is the most widely used equipment retraction method for small and medium-sized marine survey missions.

[0004] When using a simple release and recovery mode for marine survey operations, the hoisted equipment will sway under the influence of waves, and it is necessary to use manual pull ropes or poles to stop and protect it to prevent the swaying from being too large and uncontrollable. However, after the A-frame is swung out, the anti-swaying force on the rear deck of the ship and the lifting cable tension form an unstable structure, making the resultant force on the hoisted equipment not zero. When the sea conditions are complex, the equipment will sway and be difficult to control, posing a huge threat to the operators and instruments and equipment. Although manual operation has the advantages of flexibility, speed and accuracy in complex and changeable marine environments, human power is limited, and the space for manual operation is confined to the inside of the hull, which limits the anti-swaying effect in actual operations.

[0005] Therefore, small and medium-sized marine survey operations urgently need a simple and effective anti-sway device that can expand the hull structure, increase the anti-sway force points, and improve the problem of unstable structure of the hoisted equipment in the simple mode, so as to achieve the effect of enhancing the anti-sway control force, and ultimately reduce the workload of sea trial operators and improve the safety of scientific research operations. Summary of the invention

[0006] The main purpose of the present application is to provide a simple and universal ship-borne anti-sway device, which is composed of a plurality of expansion units. After arrangement, the structure of the hull is expanded to increase traction points located outside the ship for anti-swaying when releasing and recovering equipment, so that the force structure of the hoisting equipment is uniform and the resultant force is 0, thereby improving the control of the operation.

[0007] To achieve the above objectives, this application provides the following technical solutions:

[0015] The spanning portion in the middle of the extended monomer connects the fixed portion inside the ship and the extended portion outside the ship, and is used to bypass protective or obstacle structures at the edge of the ship, such as guardrails, sidewalls, and cross columns.

[0016] Furthermore, the device also includes:

[0017] When two expansion units are used, the outer side of the hull provides traction in two directions, which, combined with the traction of the anti-sway rope on the inner side of the hull, forms a traction structure in more than three directions, so that the hoisted objects are subjected to uniform force and the resultant force is 0, thereby improving the control of the anti-sway over the equipment.

[0018] According to a second aspect of the present invention, the present invention claims protection for a method for designing a simple shipborne anti-sway device, which is used to design the simple shipborne anti-sway device, and the method comprises:

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] The terms "first", "second" and "third" in this application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second" and "third" can explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. All directional indications in the embodiments of the present application (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0040] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0041] The existing anti-sway devices on the market mainly start from increasing the pulling force, increasing mechanical force to replace manpower, but mechanical force has poor flexibility when operating at sea, and is slow to respond to changes in on-site conditions. The efficiency of forcibly stopping swaying with large mechanical force is not high. In addition, there are anti-sway devices on the market that increase the anti-sway force points, but their designs are limited to the hull, such as the sides of the A-frame and the four corners of the deck. Adding pulling points in the hull can increase the stability of the equipment during operation to a certain extent, but the force from the inside of the hull always forms an unstable combined force structure with the suspended cables, which is easy to shake and difficult to put into the water.

[0042] The anti-sway device designed by the present invention is composed of multiple expansion units, which are simple in structure and easy to use. After deployment, it can form an expansion structure for the hull and form a traction point outside the hull that can hold force. The cooperation of multiple expansion units solves the problem that the anti-sway traction can only be exerted on the rear deck, resulting in unstable resultant force on the equipment, and increases the control force of the anti-sway during the release and recovery of the equipment.

[0043] The device is easy to design and manufacture, and can be designed according to the size and layout of the hull, the size and weight of the instruments that need to be released and recovered, etc. The manufactured anti-sway device extension unit can be flexibly deployed and disassembled individually or in multiple units.

[0044] According to the first embodiment of the present invention, the present invention seeks protection for a simple shipborne anti-sway device, which is applied to a hull and is characterized in that the simple shipborne anti-sway device comprises a plurality of expansion monomers, which are arranged to expand the structure of the hull, and to increase traction points located outside the hull for anti-swaying when releasing and recovering equipment, so that the force structure of the hoisting equipment is uniform and the resultant force is 0.

[0045] Furthermore, the device also includes:

[0046] A plurality of expansion monomers are installed at the stern or side of the hull, and the structure of the expansion monomer extends out of the hull by a preset distance to form a plurality of structures for anti-swaying and traction;

[0047] Each of the expansion units is an integral structure, with one end being a fixed portion and the other end being an extension portion, the end of the extension portion being provided with a hanging ring, the middle of the expansion unit being a spanning portion, and an adjustable support being provided at the lower outer side of the spanning portion.

[0048] Furthermore, the device also includes:

[0049] A fixing part, installed on the inner side of the hull, fixing the expansion unit to the hull by one or more methods of welding, bolting, and compaction, so as to provide support and control force for the part extending out of the hull;

[0050] The extension part extends out of the hull, and a hanging ring connected to the end of the extension part is used to add a stable traction point outside the hull, and the direction of the pulling force changes after the horizontal pull rope passes around the hanging ring;

[0051] The spanning portion in the middle of the extended monomer connects the fixed portion inside the ship and the extended portion outside the ship, and is used to bypass protective or obstacle structures at the edge of the ship, such as guardrails, sidewalls, and cross columns.

[0052] Furthermore, the device also includes:

[0053] When two expansion units are used, the outer side of the hull provides traction in two directions, which, combined with the traction of the anti-sway rope on the inner side of the hull, forms a traction structure in more than three directions, so that the hoisted objects are subjected to uniform force and the resultant force is 0, thereby improving the control of the anti-sway over the equipment.

[0055] 1Fixed part

[0056] The extension unit can be fixed by welding, bolts, weighting, etc. The length, shape and internal reinforcement structure of the fixing part can be adjusted according to the actual situation of the hull. The recommended length is 1-2m.

[0058] The part used to cross the obstacle between the inside and outside of the hull may be the guard plate of the side of the ship, the guardrail of the stern, the crossbar, etc. The shape of the crossing part is not limited to the arc shape, and can also be adjusted according to the shape of the hull obstacle.

[0066] According to a second embodiment of the present invention, the present invention claims a method for designing a simple shipborne anti-sway device, which is used to design the simple shipborne anti-sway device, and the method comprises:

[0067] S1: Detecting the hull to which the anti-sway device is to be added, inspecting the hull, and determining the position and space to which the anti-sway device is to be added;

[0068] S2: confirm the instruments and equipment that need to be released and recovered after adding the anti-swing device and the release and recovery methods;

[0069] S3: dividing the extension monomer of the anti-sway device into parts and further designing it, and selecting the preparation material of the extension monomer;

[0070] S4: using the selected material to manufacture an extension unit of the anti-sway device;

[0071] S5: Install one or more expansion units onto the hull and equip them with a lanyard rod, and the deployment of the anti-sway device is completed.

[0072] Furthermore, the S1 further includes:

[0073] Inspect the overall layout of the hull, examine the location where the anti-sway device needs to be added, check whether there are any objects around that need to be avoided, the structure of the rear side of the ship, examine which position can be used to fix the anti-sway device expansion unit, etc., and determine the length, width and adaptive adjustment structure of the fixing part;

[0074] The length of the fixed part of the extended single body is preliminarily designed to be no less than 1m. When there is sufficient space on the deck for installing the fixed part, the length of the fixed part is extended to 2m. If the extended part needs to bear a large load, the length of the fixed part is further extended;

[0075] Preliminary design of the shape of the spanning part. The spanning part connects the fixed part inside the hull and the extended part outside the hull. It has no fixed shape and is designed according to the blocking structure of the ship's side.

[0076] The crossing portion is designed to be close to the ship's side blocking structure;

[0077] The height of the spanning portion does not exceed 0.5m, and the width does not exceed 0.5m;

[0078] The support portion on the outer lower side of the spanning portion is designed to be an isosceles right triangle structure, and the length of the straight side is designed to be 0.3m-0.5m.

[0079] Furthermore, the S2 further includes:

[0080] Investigate winches, A-frames, cranes, and booms used to release and recover equipment;

[0081] Measure the working height AH and the maximum outreaching horizontal distance AD ​​of the hanging hook of the hanging equipment;

[0082] The maximum length of the extension portion is designed to be AD+0.5m, and the length of the extension portion is reduced while ensuring the safe storage and deployment of the equipment.

[0083] Among them, in this embodiment, the size (horizontal maximum width DD and vertical height DH) and weight DM of the instruments and equipment to be released and recovered, as well as the release and recovery process and precautions of these equipment are investigated. According to the actual needs of releasing and recovering the equipment, the length of the extension can be designed to be DD+0.8m+0.5m. The design diameter of the hanging ring can pass through the pulling cable.

[0084] The structural strength of the extension unit is designed according to the weight of the equipment, and the shaking radius of the suspended instrument is 0.2m as the safety margin. The extension unit extension should be able to provide a size of 0.2m at the end without obvious deformation. The tensile force perpendicular to the direction of expansion of the monomer.

[0085] According to the length of each part of the design and the structural strength requirements, the material for preparing the expansion unit is selected, such as solid stainless steel, I-shaped steel, steel pipe, etc. The thickness of the expansion unit of the device is recommended to be no more than 0.05m. The strength of the expansion unit can be increased by increasing the width.

[0086] If the equipment requires special protection, the design adds anti-collision material wrapped around special parts of the expansion unit.

[0087] After the design is completed, the selected material is used to manufacture the anti-swing device expansion unit, and welding, fusion and other processes are used to manufacture an integrated device expansion unit.

[0088] The fixed part of the expansion unit of the anti-sway device is fixed to the hull by welding, bolting, weighting, bundling, etc., and the extension part extends out of the hull. The fixed expansion unit is tight and will not slide, and can provide support for anti-sway. Multiple expansion units constitute a simple anti-sway device.

[0089] Since the farthest hanging ring extends a certain distance from the hull, a hanging rope rod is required to facilitate bypassing the anti-sway cable. At this point, the anti-sway device is manufactured and deployed, and the position can be adjusted according to actual use.
