Description

Technical Field

[0001] The present invention relates to the technical fields of ocean engineering and ocean towed exploration technology. More specifically, it particularly relates to an automatically depth-fixed device and system for a cable that can be quickly installed and disassembled and has self-righting attitude. Background Art

[0003] To meet certain specific detection requirements, it is necessary for detection equipment to monitor and collect relevant data at the same ocean layer. This requires that the underwater detection equipment or data collector towed behind the exploration ship must maintain navigation at the same underwater depth. However, the ocean climate and environmental conditions are harsh, and the ship in navigation is greatly affected by wind waves, surges, etc. This makes it difficult for the underwater detection equipment towed behind the ship to maintain operation at the same underwater depth. It is necessary to design a depth-fixed towed exploration system that can keep the towed cable in a taut straight state at the same underwater depth for detecting underwater detection equipment. Such an ocean depth-fixed towed exploration system can also be used for marine geological exploration. Summary of the Invention

For example, when an element is referred to as being "connected to" another element, it can be directly or indirectly connected to the other element.

[0032] In addition, the mention of "embodiment" herein means that a specific feature, structure or characteristic described in connection with the embodiment can be included in at least one embodiment of the present invention. The phrase appears at various positions in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0033] Refer to Figures 1 to 4As shown in the figure, the present invention provides an automatically depth-setting cable with self-righting attitude, which includes an upper depth-setting component, a lower depth-setting component, a snap ring component, and a quick buckle component 8. The upper depth-setting component includes a depth-setting wing plate 1, a wing plate connecting frame 2, an upper depth-setting float 3, and a cover plate 11. The lower depth-setting component includes a lower depth-setting float 7.

[0034] The open ends of the upper depth-setting float 3 and the lower depth-setting float 7 are matched to form a depth-setting float. A snap ring component for cooperating with the cable is arranged in the cavity of the depth-setting float. The wing plate connecting frame 2 is movably arranged on the surface of the upper depth-setting float 3. Depth-setting wing plates 1 are symmetrically arranged on both sides of the outer edge of the wing plate connecting frame 2 and located on both sides of the axis of the depth-setting float. The cover plate 11 is arranged on the surface of the wing plate connecting frame 2 and is connected to the upper depth-setting float 3. A quick buckle component 8 is arranged between the upper depth-setting float 3 and the lower depth-setting float 7 for quick installation and disassembly.

[0035] In this embodiment, the wing plate connecting frame 2 is limited up and down by the lower depth-setting float 7 and the cover plate 11, so that the depth-setting wing plate 1 can be adjusted by ±10° along the axial direction of the depth-setting float. Since the depth-setting wing plate 1 adopts a symmetrical structure, when there is an initial installation error, the fluid acting forces on the two depth-setting wing plates 1 will form a turning moment in the offset direction, thus realizing self-righting of the attitude.

[0036] Furthermore, to balance the gravity of the cable, the upper depth-setting float 3 and the lower depth-setting float 7 are made of solid buoyancy material with a density of 0.2 g / cm3 as the matrix, and the outer surface of the matrix is pasted with fiberglass. While meeting the buoyancy requirements, it also has sufficient structural strength.

[0037] Furthermore, the wing plate connecting frame 2 includes a connecting main body part 21 and a connecting bending part 22. The connecting main body part 21 cooperates with the surface of the upper depth-setting float 3 and the cover plate 11. The outer edge of the connecting main body part 21 extends away from the center of the depth-setting float to form a connecting bending part 22. The side surface of the connecting bending part 22 is connected to the depth-setting wing plate 1.

[0038] Furthermore, the depth-setting wing plate 1 is an arc-shaped plate, and a positioning part 101 is formed on one side surface thereof. Depth-setting force adjustment holes are arranged at intervals on the positioning part 101 and are connected and cooperated with the connecting bending part 22 of the wing plate connecting frame 2.

[0039] Specifically, the depth-setting wing plate 1 and the wing plate connecting frame 2 are connected by screws for convenient disassembly. The wing plate connecting frame 2 has threaded holes, and there are multiple depth-setting force adjustment holes on the depth-setting wing plate 1 to meet the requirements of different towing depths, that is, the depth-setting force adjustment holes where the depth-setting wing plate 1 cooperates with the wing plate connecting frame 2 can be adjusted according to the working depth requirements of the towing cable.

[0040] In this embodiment, to achieve the function of towing and depth fixation, depth-fixing wing plates 1 are symmetrically arranged on both sides of the wing plate connecting frame 2. The depth-fixing wing plates 1 are arc-shaped. When towing, the fluid flowing through the arc plate exerts a fluid force on the depth-fixing wing plates 1, forcing them to change direction, so that the automatic depth fixer can reliably reach a certain depth.

[0041] Furthermore, as the main load-bearing components, the materials of the depth-fixing wing plates 1 and the wing plate connecting frame 2 are selected as 7050 aluminum alloy with light weight, high strength and stiffness, and seawater corrosion resistance, so as to meet the requirements of overall weight and strength at the same time.

[0042] Furthermore, moving limit grooves are respectively arranged on the opposite surfaces of the wing plate connecting frame 2. The main bodies of bull's-eye ball bearings are respectively arranged on the cover plate 11 and the upper depth-fixing floating body 3. The universal balls of the bull's-eye ball bearings are all located in the corresponding moving limit grooves of the wing plate connecting frame 2.

[0043] In this embodiment, the main body of the upper bull's-eye ball bearing 10 is arranged on the cover plate 11, and the main body of the lower bull's-eye ball bearing 9 is arranged on the upper depth-fixing floating body 3. By arranging the upper bull's-eye ball bearing 10 and the lower bull's-eye ball bearing 9, the positioning error during manual quick installation can be eliminated. The universal balls of the bull's-eye ball bearings all act on the limit grooves of the wing plate connecting frame 2. The purpose is to enable the whole formed by the depth-fixing wing plates 1 and the wing plate connecting frame 2 to rotate left and right along the axis of the depth-fixing floating body, while restricting its radial movement, so that the depth-fixing force always acts in the vertical direction, avoiding inconsistent acting directions of the depth-fixing force caused by quick installation errors.

[0044] Furthermore, the snap ring assembly includes an upper snap ring 4 arranged in the upper depth-fixing floating body 3 and a lower snap ring 5 arranged in the lower depth-fixing floating body 7. The inner cavity formed by the upper snap ring 4 and the lower snap ring 5 cooperates with the cable.

[0045] In this embodiment, in order to adapt to cables with different diameter ranges, by arranging the upper snap ring 4 and the lower snap ring 5 in the positioning floating body, the inner diameters of both are matched with the cables to be adapted. The materials of the upper snap ring 4 and the lower snap ring 5 are selected as rubber, which not only has an anti-slip function, but also can directly play a role in protecting the cable.

[0046] Furthermore, convex point structures 45 are respectively arranged on the inner walls of the upper snap ring 4 and the lower snap ring 5 that cooperate with the cable, which can increase the anti-slip effect.

[0047] Furthermore, the upper depth-fixing floating body 3 and the lower depth-fixing floating body 7 are connected by a hinge 6, and a quick snap component 8 is provided to achieve quick disassembly and assembly. The quick snap component 8 includes a snap base 81, a snap hook part 82, and a snap clamping platform 83. The snap base 81 is arranged on the surface of the lower depth-fixing floating body 7, and the snap clamping platform 83 is arranged on the surface of the upper depth-fixing floating body 3; the snap hook part 82 is movably arranged on the snap base 8 and can be positioned and cooperated with the snap clamping platform 83.

[0048] In this embodiment, the upper component and the lower component of the depth setter are connected by a hinge 6 and are quickly opened and closed by a buckle assembly 8 for quick installation and disassembly operations. During the cable laying operation, after the cable is released from the winch by the operator and before the cable enters the water, the depth setter is installed on the cable; during the cable retrieval operation, after the cable emerges from the water and before the cable is wound into the winch by the operator, the depth setter is removed.

[0049] Furthermore, in order to ensure reliable installation of the wing plate connecting frame 2 and for limiting purposes, an installation groove is provided on the upper depth floating body 3 and a limiting boss 31 is formed. The wing plate connecting frame 2 is arranged in the installation groove and is limited at both ends by the limiting boss 31.

[0050] In this embodiment, to improve the applicable range of the depth setter, the depth setting wing plate 1, the upper retaining ring 4, and the lower retaining ring 5 are all set as replaceable parts. According to different depth setting depths, the airfoil shape and size of the depth setting wing plate 1 can be replaced; according to different cable types, the types of the depth setting wing plate 1 can be replaced so that it can be applied to buoyant cables and non-buoyant cables; according to different cable outer diameters, the inner diameter of the retaining ring assembly can be replaced. According to the usage situation, the depth setting wing plate 1, the upper retaining ring 4, and the lower retaining ring 5 can be made into common specification series for quick selection.

[0051] As Figure 5 shown, the present invention also provides a cable automatic depth setting system that can be quickly installed and disassembled. The cable 14 is wound and unwound by a winch 13 on a workboat 12. At least two automatic depth setters 15 are arranged at intervals on the cable 14. A combination of a hinge 6 and a quick buckle assembly 8 is used between each automatic depth setter 15 and the corresponding cable 14 to achieve quick installation and disassembly. The automatic depth setter 15 is not wound onto the drum of the winch 13, thus not affecting the normal cable laying of the winch 13.

[0052] In this embodiment, to ensure that the cable always maintains a taut straight state at the same depth, an automatic depth setter 15 is installed at a certain distance interval on the cable 14. Under the action of multiple automatic depth setters 15, the hydrodynamic force generated by the oncoming water flow during towing has a vertical depth setting force on each automatic depth setter 15, and there is also a horizontal tension force between two adjacent automatic depth setters 15, thereby ensuring that the working section of the working cable 14 can maintain the same depth and always be in a taut straight state.

[0053] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
