Description

Technical Field

[0001] This invention relates to the field of anti-ship collision interception system technology, specifically to a wave-resistant anti-ship collision interception unit and an interception system including the same. Background Technology

[0002] Many non-powered engineering vessels require anchoring and positioning during operations, and are therefore equipped with anchoring and positioning systems, including anchor winches, wire ropes, guide devices, and anchors. Because these vessels need to store engineering materials on deck, they require a large deck area. Consequently, the winches in the anchoring system are often placed in compartments below the main deck. This leads to a problem: the wire rope connecting the winch and the anchor needs to pass through the main deck, requiring an opening in the main deck for the wire rope to pass through. The wire rope is used in conjunction with guide pulleys, and the deck opening is usually fitted with a sleeve through which the wire rope passes. Due to the deck opening, in strong winds and waves, water can accumulate in the compartments, potentially capsizing the vessel. Therefore, when the vessel's anchoring system does not require rope reeling or unreeling, the deck opening needs to be sealed to ensure weathertightness; conversely, when the vessel needs to reel in or unreel the wire rope, the opening needs to remain open to allow for the movement of the wire rope.

[0003] To address the above issues, some engineering vessels sacrifice deck space by placing the anchor winch directly on the deck to avoid openings; others use polyurethane foam to seal the holes, but this method has the following disadvantages:

[0004] A. The lubricating oil on the surface of the wire rope may affect the adhesion of the polyurethane foam, thus failing to meet the weather tightness requirements of the classification society.

[0005] B. When it is necessary to reel in or unleash the wire rope, the polyurethane foam must be removed. However, the dried foam is difficult to remove and requires the use of machinery.

[0006] C. The openings in the deck sometimes need to be sealed and sometimes need to be unobstructed. Polyurethane foam is a consumable, which increases costs. In addition, there are certain operational requirements for the use of polyurethane foam.

[0007] Therefore, how to provide a weatherproof device for steel wire ropes that can avoid the above-mentioned drawbacks has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0008] To achieve the above objectives, the present invention provides a weatherproof device for steel wire ropes threaded through decks. The specific technical solution is as follows:

[0009] A weatherproof device for steel wire ropes passing through decks includes two identical semi-rigid splice bodies. Each semi-rigid splice body comprises an integrally formed upper splice body and a lower splice body arranged vertically. The faces of the two upper splice bodies facing each other are both upper splice surfaces. Each upper splice surface includes a circumferentially concave covering surface located at its center and two upper vertically contacting surfaces located on either side of the circumferentially concave covering surface. The cross-section of the circumferentially concave covering surface is semi-circular, and the radius of the semi-circular shape is larger than the radius of the steel wire rope. The faces of the two lower splice bodies facing each other are both lower splice surfaces. Each lower splice surface includes a lower circumferentially concave covering surface located at its center and two upper vertically contacting surfaces located on either side of the lower circumferentially concave covering surface. On its two lower vertical mating surfaces, the cross-section of the lower circumferential covering surface is semi-circular, and the radius of the semi-circular shape is larger than the radius of the sleeve. On both of the two opposing circumferential covering surfaces, a rubber layer is laid to form a wire rope covering chamber with an inner diameter smaller than the diameter of the wire rope and a full circular cross-section. On both of the two opposing lower circumferential covering surfaces, a rubber layer is laid to form a sleeve covering chamber with an inner diameter smaller than the diameter of the sleeve and a full circular cross-section. It also includes a locking structure fitted on the outside of the two semi-rigid spliced ​​bodies. The locking structure has a locked state and an unlocked state. In the locked state, the two semi-rigid spliced ​​bodies are in a stable spliced ​​state. In the unlocked state, the two semi-rigid spliced ​​bodies are in a separated state.

[0010] Preferably, the locking structure is a clamp.

[0011] Preferably, there are two clamps, namely an upper clamp and a lower clamp. The upper clamp is fitted on the outside of the two upper half splicing bodies that are spliced ​​together, and the lower clamp is fitted on the outside of the two lower half splicing bodies that are spliced ​​together.

[0012] Preferably, upper slots are provided on the outer side walls of both upper splicing bodies corresponding to the location of their rubber layers, and the two upper slots form a complete slot to accommodate the upper clamp. Lower slots are provided on the outer side walls of both lower splicing bodies corresponding to the location of their rubber layers, and the two lower slots form a complete slot to accommodate the lower clamp.

[0013] Preferably, each of the two opposite side walls of the sleeve is provided with a lower eye ring, and each of the two lower half splices is provided with an upper eye ring corresponding to the two lower eye rings, with a chain connecting the corresponding upper and lower eye rings.

[0014] Preferably, the outer surface of the semi-rigid splice is a semi-circular surface.

[0015] The weatherproof device for steel wire ropes passing through decks provided by this invention has the following technical advantages:

[0016] When the ship does not need to reel in or extend the wire rope, the device is fitted over the wire rope and its sleeve, and then secured with two clamps. The rubber layer ensures full contact with the wire rope and sleeve to guarantee weather tightness at the opening. When the ship needs to reel in or extend the wire rope, the clamps are removed, the device is released, and it is suspended from the sleeve by a chain and eyelet for easy storage. The main body is designed as two identical semi-rigid spliced ​​parts for easy loading and unloading. Attached Figure Description

[0021] like Figure 1-2 As shown, Figure 1 A schematic diagram of the structure of a weatherproof device for steel wire ropes passing through a deck provided by the present invention; Figure 2 for Figure 1 A top view of a semi-rigid spliced ​​structure.

[0022] Combination Figure 1-2In one specific embodiment, a weatherproof device for a steel wire rope passing through a deck includes two identical semi-rigid splice bodies 1. Each semi-rigid splice body 1 includes an integrally formed upper splice body 2 and a lower splice body 3 arranged vertically. The surfaces of the two upper splice bodies 2 facing each other are upper splice surfaces. Each upper splice surface includes a circumferentially concave covering surface 4 located at its center and two upper vertically fitting surfaces 5 located on both sides of the circumferentially concave covering surface 4. The cross-section of the circumferentially concave covering surface 4 is semi-circular, and the radius of the semi-circular shape is larger than the radius of the steel wire rope 6. The surfaces of the two lower splice bodies facing each other are lower splice surfaces. Each lower splice surface includes a lower circumferentially concave covering surface located at its center and two upper vertically fitting surfaces 5 located on both sides of the lower circumferentially concave covering surface 3. The lower vertical contact surfaces are located on both sides of the sleeve 7. The cross-section of the lower circumferential covering surface is semi-circular, and the radius of the semi-circular shape is larger than the radius of the sleeve 7. Rubber layers 8 are laid on the two opposite circumferential covering surfaces 4 to form a wire rope covering chamber with an inner diameter smaller than the diameter of the wire rope 6 and a full circular cross-section. Rubber layers 8 are laid on the two opposite lower circumferential covering surfaces to form a sleeve covering chamber with an inner diameter smaller than the diameter of the sleeve 7 and a full circular cross-section. The sleeve also includes a locking structure fitted on the outside of the two semi-rigid splicing bodies 1. The locking structure has a locked state and an unlocked state. In the locked state, the two semi-rigid splicing bodies 1 are in a stable splicing state. In the unlocked state, the two semi-rigid splicing bodies 1 are in a separated state.

[0023] In one specific embodiment, the locking structure is a clamp.

[0024] Furthermore, there are two clamps, namely an upper clamp 9 and a lower clamp 10. The upper clamp 9 is fitted on the outside of the two upper half splicing bodies 2 that are spliced ​​together, and the lower clamp 10 is fitted on the outside of the two lower half splicing bodies 3 that are spliced ​​together.

[0025] In one specific embodiment, upper slots are provided on the outer side walls of the two upper splice bodies 2 corresponding to the positions of their rubber layers 8, and the two upper slots form a complete slot to accommodate the upper clamp 9. Lower slots are provided on the outer side walls of the two lower splice bodies 3 corresponding to the positions of their rubber layers 8, and the two lower slots form a complete slot to accommodate the lower clamp 10.

[0026] like Figure 1 As shown, in one specific embodiment, lower eye rings 11 are provided on both opposite side walls of the sleeve 7, and upper eye rings 12 corresponding to the two lower eye rings 11 are provided at the bottom of the two lower half splice bodies 3. A chain 13 connects the corresponding upper eye rings 12 and lower eye rings 11.

[0027] Furthermore, the outer surface of the semi-rigid splice 1 is a semi-circular surface.

[0028] When the vessel does not need to retract or extend the wire rope 6, the device is fitted onto the wire rope 6 and its sleeve 7, and then secured with two clamps. The rubber layer 8 is in full contact with the wire rope 6 and the sleeve 7 to ensure weather tightness at the opening. When the vessel needs to retract or extend the wire rope 6, the clamps are removed, the device is released, and it is suspended from the sleeve 7 by the chain 13 and eyelet for easy storage. The main body is designed as two identical semi-rigid spliced ​​bodies 1 for easy loading and unloading.

[0029] To reduce weight, the overall thickness of the device should not be too thick, generally 30-50mm. Since the surface of the wire rope 6 is lubricated with oil and needs to be installed and removed under relatively low pressure, an oil-resistant soft rubber layer, such as soft nitrile rubber, is selected.
