Description

Technical Field

[0001] The present invention relates to the technical field of ship anchor chains, in particular to an anti-entanglement anchor chain for ship mooring. Background Art

[0002] The ship's anchor chain is a steel chain connecting the hull and the anchor. The anchor chain is composed of multiple anchor chain links connected to each other and is usually assembled in "sections". The length of the entire anchor chain depends on the tonnage and needs of the ship. Anchor chain entanglement and knotting are more common when the anchor chain is collected, which is related to factors such as the anchoring speed. The current anti-entanglement anchor chains for ship mooring are mostly simple steel chain structures. It is not convenient for staff to understand the state of the anchor when anchoring, which easily causes the anchor chain to accumulate, and it is easy to cause the anchor chain to be entangled with the anchor arm. At the same time, the chain is prone to twisting when anchoring, and it is not convenient to automatically adjust the position after automatic twisting adaptation when the anchor chain is collected. Excessive torsional force on the chain link will affect its life and increase the risk of entanglement. It is also not convenient for staff to understand the bending state of the anchor chain in real time when the chain link is lowered, and to recover it in time. After the anchor chain is folded, it is easy to cause entanglement.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

At the same time, the electromagnet can be used to assist in positioning when recovering the anchor, ensuring that the chain links are kept vertically when the anchor chain is recovered and recovered by the anchor chain recovery wheel. At the same time, the positioning column can be used to prevent the rotating connecting plate and the rotating mounting plate from rotating arbitrarily, which can improve the stability of anchoring.

[0017] The bending detection parts can be used for bending detection. The detection work can be carried out when a row of chain links are bent, which can reduce the risk of entanglement of the structure. It can also be used to detect chain link torsion, excessive wear and bending accumulation. A row of chain links can be fully inspected to avoid local omissions. The structural detection is simple and accurate, and it does not affect the flexibility of the row of chain links themselves. Because once a row of chain links fails to be tensioned and pulled and released, the release speed is fast, and when docking occurs, the row of chain links is prone to bending and no longer maintains a pulled state. The accumulated anchor chains are prone to local bending and twisting when under stress, which destroys the natural arrangement of the chain links and increases the risk of cross entanglement.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1 to 12 As shown:

[0034] The present invention provides a technical solution: an anti-entanglement anchor chain for ship mooring, comprising an anchor chain connecting portion 1, a torsion reset member 2 installed on the anchor chain connecting portion 1, the torsion reset member 2 being used to adjust the anchor chain; an anchor anti-entanglement member 3 installed on the anchor chain connecting portion 1; the anchor anti-entanglement member 3 being used to prevent the anchor chain from being entangled with the anchor; a chain link connecting portion 4 installed on the anchor chain connecting portion 1; a row of connecting pull-back members 5 installed on the chain link connecting portion 4, and a bending detection member 6 installed on each of the row of connecting pull-back members 5 ; A row of bending detection parts 6 are connected inside the chain link connector 4; the anchor chain connecting part 1 includes: chain links 101 and anchor connecting buckles 102, the chain links 101 are provided in a row, and the chain links 101 in a row are divided into two sections and are connected to each other; the interval between the two sections of chain links 101 is used to be connected by a torsion reset member 2; the end chain links 101 are sleeved with an anchor connecting buckle 102; the anchor connecting buckle 102 is provided with two through holes, and the two through holes on the anchor connecting buckle 102 are used to connect the anchor through an axle pin.

[0035] The anchor chain connection part 1 further includes: a crosspiece 103, a crosspiece 103 is fixedly welded in the middle of a row of chain links 101; the torsion reset part 2 includes: a torsion connection buckle 201, a butt buckle 202, a rotation connection plate 203, a rotation mounting plate 204 and a torsion tension spring 205, the torsion connection buckle 201 is sleeved on the chain link 101; the butt buckle 202 is sleeved on the chain link 101; the rotation connection plate 203 is fixedly installed on the torsion connection buckle 201; the rotation mounting plate 204 is fixedly installed on the butt buckle 202; the rotation mounting plate 204 is rotatably installed on the rotation connection plate 203; the torsion connection buckle 201 and the butt buckle 202 Used to connect a row of chain links 101; a torsion tension spring 205 is fixedly installed on the rotating connecting plate 203, and the end of the torsion tension spring 205 is connected to the rotating mounting plate 204; the torsion connecting buckle 201 and the docking buckle 202 are used to adapt to the torsion of a row of chain links 101; the torsion reset member 2 also includes: an electromagnet 206 and a positioning column 207, and there are two electromagnets 206, which are fixedly installed on the inner side of the rotating connecting plate 203 and the rotating mounting plate 204 respectively; the two electromagnets 206 are magnetically attracted to each other; a positioning column 207 is slidably inserted on the rotating mounting plate 204, and the positioning column 207 is an arc-shaped structure; the positioning column 20 7 is provided with a spring at the tail, and the spring at the tail of the positioning column 207 is located inside the docking buckle 202. The number of chain links 101 and the torsion reset member 2 is set according to demand. The torsion reset member 2 can be used to adapt to the torsion of a row of chain links 101 when anchoring, which can reduce the risk of entanglement between a row of chain links 101 due to torsion force, reduce torsion force, and improve the anti-entanglement effect of this structure. At the same time, the electromagnet 206 can be used to assist in the position when recovering the anchor, ensuring that the chain link 101 is kept vertically when the anchor chain is recovered and recovered by the anchor chain recovery wheel. At the same time, the positioning column 207 can be used to avoid rotating the connecting plate 203 and rotating the mounting plate The 204 can be rotated arbitrarily to improve the stability of anchoring. The upper chain link 101 is connected to the anchor chain reel, and the arc structure at the end of the positioning column 207 can be used to automatically retract. When the chain link 101 is recovered, the two electromagnets 206 can be energized to attract each other, and the rotating connecting plate 203 and the rotating mounting plate 204 can be corrected to avoid affecting the winding and conveying of the anchor chain wheel. If the lowering speed is too fast, the anchor chain may accumulate around the anchor, and the chain link will sink into the seabed mud due to its own weight. When the anchor chain accumulation depth exceeds the bottom gripping depth of the anchor, the backward pulling force of the ship will cause the accumulated chain link to pass through under the anchor crown and anchor claw, forming a semi-ring structure, which will eventually lead to entanglement.

[0036] Among them, the anchor anti-winding component 3 includes: an anchor anti-winding rod 301, an anti-winding connecting plate 302 and an anchor arm detection switch 303. The anchor anti-winding rod 301 is fixedly installed on the anchor connecting buckle 102; anti-winding connecting plates 302 are fixedly installed on both sides of the anchor anti-winding rod 301; anchor arm detection switches 303 are fixedly installed on the two anti-winding connecting plates 302; the anchor arm detection switch 303 is used to detect the anchor arm; the anchor anti-winding component 3 also includes: an anchor chain switch 304, which is fixedly installed on the anchor anti-winding rod 301; the end chain link 101 is used to squeeze the anchor chain switch 304; the anchor chain switch 304 and the anchor arm detection switch 303 are respectively connected to indicator lights. The anchor anti-winding component 3 can be used to detect the anchor arm. It is used to detect the hanging tensioning effect between the anchor and the anchor chain when the anchor is dropped, which can prevent the anchor chain from being entangled on the anchor arm after the anchor is dropped, causing the anchor chain to be entangled when the anchor is subsequently raised, resulting in subsequent tedious entanglement and disassembly work. The detection of this structure is simple and direct, and can directly prompt. When a row of chain links 101 are anchored, the anchor reaches the seabed first. At this time, the anchor should be kept towed. The chain link 101 at the end of a row of chain links 101 is skewed, and the middle part cannot keep dragging the anchor connecting buckle 102. At this time, the anchor connecting buckle 102 is prone to entanglement risk. When the anchor connecting buckle 102 is skewed, it will drive the anchor arm detection switch 303 on the skewed side to squeeze the anchor arm, and at this time it can be prompted that the anchor has touched the bottom.

[0037] The chain link connector 4 includes: a crossbar connecting ring 401, an elastic rubber tube 402, a water supply pump 403 and a water spray hole 404. The crossbar connecting ring 401 is provided with a circle, and a circle of crossbar connecting rings 401 are fixedly installed on the crossbar 103 by bolts; an elastic rubber tube 402 is fixedly installed on a row of crossbar connecting rings 401; the elastic rubber tube 402 is an elastic and retractable structure; the water supply pump 403 is fixedly installed at the bottom end of the elastic rubber tube 402; the elastic rubber tube 40 2 is provided with a row of water spray holes 404; the row of water spray holes 404 are respectively used for discharging water to flush the chain links 101; the water supply pump 403 is used to extract seabed water, and the chain link connector 4 adopts an elastic structure, which can adapt to the expansion and contraction of the row of chain links 101. The structure is simple and reasonable, and the seawater can be sucked and then sprayed to the row of chain links 101 for flushing, which can improve the cleaning effect of the structure on the row of chain links 101 and reduce the risk of contamination of the row of chain links 101.

[0038] The second embodiment, on the basis of the first embodiment, the connecting pull-back member 5 includes: a pull-back mounting plate 501, a closed sleeve 502 and a pulling steel bar 503, the pull-back mounting plate 501 is provided in a row, a row of pull-back mounting plates 501 is a group of two, a row of pull-back mounting plates 501 is spaced and aligned with a row of cross bar connecting rings 401; a row of pull-back mounting plates 501 is respectively provided with a circle of through holes; a closed sleeve 502 is fixedly installed on the lower pull-back mounting plate 501 in each group of pull-back mounting plates 501, and a pulling steel bar 503 is sealed on the closed sleeve 502, and the end of the pulling steel bar 503 is connected to the side of the upper pull-back mounting plate 501 in each group of pull-back mounting plates 501; a row of pulling steel bars 503 is used to adapt to the bending of the anchor chain; the connecting pull-back member 5 also includes: a detection tension spring 504, a front electrical sleeve 505 and a rear electrical sleeve 506, a detection tension spring is sleeved inside the closed sleeve 502 504; a front electrical sleeve 505 and a rear electrical sleeve 506 are fixedly installed inside the pullback mounting plate 501, and a gap is provided between the front electrical sleeve 505 and the rear electrical sleeve 506; the front electrical sleeve 505 and the rear electrical sleeve 506 are conductive copper sheets; the front electrical sleeve 505 is located on the outside of the detection tension spring 504; the bending detection part 6 includes: a detection slide 601 and an electrical spring 602, the detection slide 601 is fixedly installed on the end of the pulling steel bar 503; the detection slide 601 is sleeved on the inside of the closed sleeve 502 on the same side; the end of the detection tension spring 504 is connected to the side of the detection slide 601, and the other end of the detection tension spring 504 is connected to the inside of the closed sleeve 502; a circle of electrical spring 602 is fixedly installed on the outside of the detection slide 601, and each circle of electrical spring 602 has an elastic conductive structure; a circle of electrical spring 602 is located at the gap between the front electrical sleeve 505 and the rear electrical sleeve 506;The front electrical sleeve 505, the rear electrical sleeve 506 and the electrical spring clip 602 are connected in series with indicator lights, and the bending detection part 6 can be used for bending detection. It can be used to detect when a row of chain links 101 are bent, which can reduce the risk of entanglement of the structure and can be used to detect torsion, excessive wear and bending accumulation of the chain links 101 at the same time. This structure can fully detect the entire row of chain links 101 to avoid local omissions. The structural detection is simple and accurate, and at the same time does not affect the flexibility of the row of chain links 101 itself. Because once a row of chain links 101 fails to be tensioned and pulled and released, the release speed is fast, and when docking occurs, the row of chain links 101 is prone to bending and no longer maintains a pulled state. The accumulated anchor chains are prone to local bending and torsion when under stress, which destroys the natural arrangement of the chain links and increases the risk of cross-entanglement. When the anchor chain is loose, lack of tension, ocean currents, wind direction changes or ship deviations will cause the chain Irregular movement of the chain link can cause adjacent links to misalign or cross. At the same time, this structure can also take into account wear detection, preventing excessive wear of a row of chain links 101 from going undetected. When wear occurs in a row of chain links 101, the distance between the two chain links 101 will increase. At this time, the increased distance between the crosspieces 103 will drive the crosspiece connecting ring 401 to stretch the elastic rubber tube 402, and also drive the closed sleeve 502 to pull the power spring 602 on the detection slide 601 to contact the rear power sleeve 506, and the external indicator light will be powered on to indicate the presence of the wear. Similarly, if excessive torsion occurs in an adjacent chain link 101, the elastic rubber tube 402 will be stretched. If the adjacent chain link 101 bends, causing the elastic rubber tube 402 to also bend, whether the bending direction is to one side of the row of chain links 101, that is, inward or outward, the external indicator light will be powered on to indicate the presence of the wear, ensuring comprehensive detection.

[0039] The working principle of this embodiment is as follows: first, when dropping anchor, the chain link 101 is continuously discharged. If the anchor or the chain link 101 is twisted to a certain extent, when the twisting force is large, the rotating connecting plate 203 and the rotating mounting plate 204 rotate. The arc structure at the end of the positioning column 207 can automatically retract. The spring at the tail of the positioning column 207 can be compressed to adapt to the twisting force. The torsion tension spring 205 plays the role of elastically limiting the torsion angle between the rotating connecting plate 203 and the rotating mounting plate 204. When retrieving the chain link 101, the two electromagnets can be used to retract the two electromagnets. When the chain link 102 is skewed, the middle part cannot keep dragging the anchor connecting buckle 102, and the anchor connecting buckle 102 is easily entangled. When the anchor connecting buckle 102 is skewed, it will cause the skewed one to be dragged. The anchor arm detection switch 303 on the side is squeezed to the anchor arm of the ship, and the anchor arm detection switch 303 can control the external indicator light to light up. At the same time, if the chain link 101 is lowered too quickly, the chain link 101 at the end will directly squeeze the anchor chain switch 304, which can prompt that the anchor has touched the bottom. The water supply pump 403 is used to suck water and the water is sprayed through the spray hole 404 to flush the chain link 101 and reduce attachments. When a row of chain links 101 are worn, the distance between the two chain links 101 will increase. At this time, the distance between the crosspieces 103 increases, driving the crosspiece connecting ring 40 1 stretches the elastic rubber tube 402, which also drives the closed sleeve 502 to pull the power spring 602 on the detection slide 601 to contact the power sleeve 506, and the external indicator light will be powered on to prompt. Similarly, if the adjacent chain link 101 is excessively twisted, the spacing between the horizontal connecting rings 401 in the corresponding area will increase, and the elastic rubber tube 402 will be stretched, which will also be detected and prompted. At the same time, if the adjacent chain link 101 is bent, the elastic rubber tube 402 will also be bent. Whether the bending direction is to one side of a row of chain links 101, that is, inward, or outward, as shown in the attached figure, Figure 12 As shown, if it bends toward one side of a row of chain links 101, the elastic rubber tube 402 is stretched, and the power-connecting spring 602 contacts the rear power-connecting sleeve 506. Conversely, if it bends outward, the elastic rubber tube 402 is in a contracted state. Under the pull of the detection tension spring 504, the closed sleeve 502 pulls the power-connecting spring 602 on the detection slide column 601 to slide inward and contact the front power-connecting sleeve 505. At this time, the external indicator light will be powered on to light up to ensure comprehensive detection.
