Description

Technical Field

[0001] The present invention relates to the technical field of deepwater deployment equipment, and in particular to an improvement in the structure of an impact force-sensing self-releasing anchor device used for deployment. Background Art

[0002] As humans continue to develop and utilize marine resources, a wide range of underwater equipment has emerged. In many cases, underwater equipment needs to be fixed to the seabed through anchor structures to ensure the stability and safety of the equipment. Traditional anchor systems are mostly used in ships and buoy systems, and most use anchor chains to drive the anchor hook down. After the anchor hook falls to the seabed, it is easy for it to hit obstacles, causing the anchor hook to become loose and fail.

[0003] There are also some impact-sensing self-releasing anchor devices with complex structures. For example, the impact-sensing self-releasing anchor device disclosed in the patent document with patent number: 201420799591.9 and patent name: Embedded Submarine Anchoring System is not only complex in structure, but also cumbersome to operate during use. Similarly, the patent number is: 201610124680.7, a ship anchor with a complex structure and high production cost.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application.

[0015] When the fluke limiting member is in the second position, the fluke limiting member is disengaged from the fluke, the fluke extends from the anchor body containing shell and is tilted and unfolded below the horizontal plane, an insertion space is formed between the fluke and the anchor body containing shell, and the locking member pops out and extends into the insertion space and abuts against the bottom surface of the fluke to limit it.

[0016] In some embodiments of the present application,

[0017] An opening portion is formed on the anchor body containing shell to facilitate the deployment and extension of the anchor claw. There are multiple opening portions, which are evenly arranged along the circumference of the anchor body containing shell. Each opening portion is opened from top to bottom along the height direction of the anchor body containing shell, and a limiting protrusion is formed at the opening portion to limit the deployment angle of the anchor claw.

[0018] In some embodiments of the present application,

[0019] A mutually cooperating clamping structure is provided between the fluke and the fluke limiting member, and the clamping structure comprises a fluke opening provided on a side wall of the fluke and a clamping hook provided on the fluke limiting member.

[0020] In some embodiments of the present application, the fluke limiter is a limit rod, which includes a first rod segment and a second rod segment, and the angle between the first rod segment and the second rod segment is 150-170 degrees.

[0021] In some embodiments of the present application, a fixing seat is arranged on the anchor body containing shell, a fixing piece is provided in the fixing seat, and the elastic tensile member is fixedly connected to the fixing piece.

[0022] In some embodiments of the present application, the elastic locking component includes: a locking member, on which a limited abutment portion is provided, the limited abutment portion and the fixing seat are arranged opposite to each other;

[0023] The elastic element is sleeved on the locking member, with one end abutting against the position-limiting abutting portion and the other end abutting against the fixing seat.

[0024] In some embodiments of the present application, a sliding guide structure that cooperates with each other is provided between the anchor body containing shell and the locking member.

[0025] In some embodiments of the present application, the side surface of the fluke and the bottom surface of the fluke are connected by a smoothly transitioning curved surface.

[0026] In some embodiments of the present application, the anchor bracket includes multiple connecting plates, which are arranged in sequence along the circumference of the anchor body containing shell, and an installation space is formed between adjacent connecting plates. The fluke is located in the installation space and is hinged to the connecting plates on both sides.

[0027] An underwater communication device, comprising: an upper beacon device, and an impact force sensing self-releasing anchor device,

[0028] The upper beacon device includes:

[0029] an upper section shell, and an underwater releaser disposed in the upper section shell;

[0030] A cable, with both ends connected to the anchor limiter and the underwater releaser, and having a preset length;

[0031] The fixed depth release device is connected to the cable buffer device via a connecting rope, and the cable buffer device is connected to the separation column via a connecting rope;

[0036] When the anchor device sinks to the seabed and is separated from the upper beacon device, the cable between the anchor device and the upper beacon device is tightened, and the cable drives the fluke limiter to move to the second position, thereby deploying the anchor device.

[0037] Compared with the prior art, the advantages and positive effects of the present invention are:

[0038] The impact-sensing self-releasing anchor device structure of the present invention is tilted below the horizontal plane after deployment, so that it has a small downward inclination angle relative to the horizontal plane, and the anchor claw has a large deployment angle;

[0039] After the elastic locking piece is automatically pushed into the bottom of the anchor claw, it forms a self-locking state. Compared with traditional anchors, the friction between the entire anchor claw and the seabed is greater, and the contact area with the seabed is increased, which prevents the anchor from tipping over and effectively prevents the anchor from dragging.

[0040] The impact-sensing self-releasing anchor device of the present invention can realize opening or closing of the anchor claw and deployment of the anchor claw only through the cooperation of the anchor claw limiter, the elastic locking component and the anchor claw. The structure is simple. When deploying, only an external force needs to be applied to the anchor claw limiter to rotate it relative to the anchor bracket to realize automatic deployment of the anchor claw. The deployment is convenient, simple and quick.

[0041] Other features and advantages of the present invention will become more apparent after reading the detailed description of the present invention in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0049] The present invention provides an embodiment of an impact force sensing self-releasing anchor device, comprising:

[0050] An anchor body containing shell 610, wherein a receiving space is formed in the anchor body containing shell 610;

[0051] In some embodiments, the anchor containment shell 610 is configured to be cylindrical so as to be dropped into the water for deployment, and the top of the anchor containment shell 610 is open.

[0052] An anchor bracket 620, located in the accommodation space and fixedly connected to the anchor body containing shell 610;

[0053] The fluke assembly 630 is located in the accommodation space and includes a plurality of flukes 631 hinged to the anchor bracket 620;

[0054] The flukes 631 may be arranged in a plurality and evenly arranged along the circumference of the anchor body containment shell 610 .

[0055] When not deployed, the fluke assembly 630 is stored in the anchor body containment shell 610 to facilitate transportation. When deployed, the fluke 631 can be unfolded.

[0056] The elastic tensile member 640 is fixed on the anchor body containing shell 610;

[0057] The elastic stretching member 640 is a spring and is fixed to the bottom wall of the anchor body containing shell 610.

[0058] During installation, a fixing seat 670 can be provided on the bottom wall of the anchor body containing shell 610, and a fixing member 680 can be fixedly connected to the fixing seat 670. The fixing member 680 can be a fixing bolt, and one end of the spring is fixed on the fixing thread.

[0059] The fluke stopper 650 is rotatably connected to the anchor bracket 620 and connected to the elastic stretching member 640. The fluke stopper 650 can be rotated relative to the anchor bracket 620 to be in the first position or the second position.

[0060] When the anchor is not deployed, the fluke limiting member 650 rotates relative to the anchor support 620 and rotates to the first position, and is engaged in the fluke 631 to limit the fluke 631 .

[0061] To ensure that when one end of the fluke stopper 650 is inserted into the fluke 631, the other end of the fluke stopper 650 does not tilt upward and lose balance, the elastic tensioning member 640 is connected to the other end of the fluke stopper 650. The elastic tensioning member 640 can apply a downward elastic tensioning force to the fluke stopper 650 to keep it stable.

[0062] Furthermore, pulling the fluke limiting member 650 by the elastic stretching member 640 will not interfere with the rotation of the fluke limiting member 650 relative to the anchor bracket 620 .

[0063] The elastic locking member 660 is used to limit the position of the fluke 631;

[0064] When the fluke limiting member 650 is in the first position, the fluke limiting member 650 is clamped in the fluke 631, and the end of the elastic locking member 660 abuts against the side of the fluke 631 to limit the fluke 631;

[0065] When the fluke stopper 650 is in the first position, the fluke stopper 650 is stuck in the fluke 631, exerting a force on the fluke 631 in the direction of approaching the fluke stopper 650, while the elastic locking member 661 abuts against the inner side wall of the fluke 631, exerting a reverse force on the fluke 631. The fluke 631 is fixed in position inside the anchor housing 610 by the cooperation between the fluke stopper 650 and the elastic locking member 660, so that it will not unfold or fall over in the stowed state.

[0066] When the fluke limiting member 650 is in the second position, the fluke limiting member 650 is disengaged from the fluke 631, and the fluke 631 extends from the anchor body containing shell 610 and is tilted and unfolded below the horizontal plane. An insertion space is formed between the fluke 631 and the anchor body containing shell 610, and the locking member pops out and extends into the insertion space and abuts against the bottom surface of the fluke 631 to limit its position.

[0067] The fluke stopper 650 is rotatable relative to the anchor bracket 620 , so its position is variable. When subjected to an external force, the fluke stopper 650 rotates relative to the anchor bracket 620 from a first position to a second position where it can be disengaged from the fluke 631 .

[0068] Specifically, the impact-sensing self-releasing anchor device 600 of this embodiment can be deployed in conjunction with a cable, which can be a separate section of rope connected to an upper beacon device. The cable has a preset length.

[0069] During connection, one end of the cable is connected to one end of the fluke stopper 650, and the other end is connected to the upper beacon device.

[0070] The upper beacon equipment can separate from the anchor device and float up after entering the water.

[0071] During deployment, the impact-sensing self-release anchor device is thrown into the water. When the anchor device sinks to the seabed and separates from the upper beacon device, the upper beacon device floats up and the anchor device sinks. When the distance between the two reaches the cable length, the cable between the anchor device and the upper beacon device is tightened, and the impact force of the cable drives the anchor claw limiter to move. Under the action of the cable tensioning force, the end of the anchor claw limiter 650 will be pulled upward and swung, thereby realizing the separation of the anchor claw limiter 650 from the anchor claw 631, so that the anchor claw 631 is limited by the anchor claw limiter 650, and the anchor claw 631 is opened and deployed.

[0072] During separation, the cable moves and connects to the fluke stopper 650 , which drives the fluke stopper 650 to rotate and separate from the fluke 631 .

[0073] After separation, the limit of the fluke 631 is eliminated, and the fluke 631 rotates and opens relative to the anchor bracket 620. After the fluke 631 rotates and opens, an insertion space is formed between its bottom and the anchor body containing shell 610. The locking member extends into this space and abuts against the bottom of the fluke 631 to limit its position. In this way, due to the limit of the locking member, the fluke 631 will no longer rebound and reset.

[0074] The impact-sensing self-releasing anchor device 600 of this embodiment is tilted below the horizontal plane after deployment, so that it has a small downward inclination angle relative to the horizontal plane, and the fluke 631 has a large deployment angle.

[0075] After the elastic locking member 661 is automatically pushed into the bottom of the anchor claw 631, it forms a self-locking state. Compared with traditional anchors, the friction between the entire anchor claw 631 and the seabed is greater, and the contact area with the seabed is increased, which prevents the anchor from tipping over and effectively prevents the anchor from dragging.

[0076] In this embodiment, the impact-sensing self-release anchor device 600 can open or close the fluke 631 and deploy the fluke 631 simply by cooperating with the fluke limiter 650, the elastic locking member 660, and the fluke 631. The structure is simple. During deployment, only an external force needs to be applied to the fluke limiter 650 to rotate it relative to the anchor bracket 620 to achieve automatic deployment of the fluke 631. Deployment is convenient, simple, and quick.

[0077] In some embodiments of the present application, an opening portion 611 is formed on the anchor body containing shell 610 to facilitate the deployment and extension of the fluke 631. A plurality of opening portions 611 are provided, which are evenly arranged along the circumference of the anchor body containing shell 610. Each opening portion 611 is opened from top to bottom along the height direction of the anchor body containing shell 610.

[0078] The opening 611 is a long strip-shaped opening, which facilitates the fluke 631 located inside to extend outward through the opening and then unfold.

[0079] The number of openings is set to match the number of flukes 631 .

[0080] A limiting protrusion 612 is provided at the opening 611. The limiting protrusion 612 is a limiting wall extending upward from the anchor body containment shell 610. When the fluke 631 is unfolded, the bottom of the fluke 631 abuts against the extended limiting wall to limit its rotation and unfolding angle.

[0081] In some embodiments of the present application,

[0082] A cooperating latching structure is provided between the fluke 631 and the fluke stopper 650 . The latching structure includes a fluke opening 632 provided on a side wall of the fluke 631 and a latching hook 651 provided on the fluke stopper 650 .

[0083] The fluke limiting member 650 is configured to limit the fluke 631 by locking the hook portion 651 at the end thereof in the opening of the side wall of the fluke 631 .

[0084] In some embodiments, the fluke opening 632 is provided at an upper region of the fluke 631 , the fluke stopper 650 is positioned above the fluke 631 , and the locking member is disposed at a bottom portion of the fluke 631 .

[0085] In some embodiments of the present application, the fluke limiter 650 is a limit rod including a first rod segment and a second rod segment, and the angle between the first rod segment and the second rod segment is 150-170 degrees.

[0086] The first rod section can be set as a horizontal rod section, and the second rod section can be set as an inclined rod section, with a certain angle between the two, so that the limit rod forms a kind of lever, so as to facilitate separation from the fluke 631 when the fluke limiter 650 is subjected to force.

[0087] In some embodiments of the present application, the elastic locking component 660 includes: a locking member 661, a limited abutting portion 662 is provided on the locking member 661, and the limited abutting portion 662 is arranged opposite to the fixing seat 670;

[0088] The locking member 661 includes a locking body, an extension portion extending from the locking body, and the limiting abutment portion 662 is a limiting abutment step formed between the locking body and the extension portion.

[0089] The elastic element 663 is sleeved on the extension portion of the locking member 661 , with one end abutting against the limiting abutting portion 662 and the other end abutting against the fixing seat 670 .

[0090] The elastic element 663 is a spring.

[0091] When the fluke 631 is not opened, the spring applies an elastic force to the locking member 661 so that the end of the locking member 661 abuts against the side of the fluke 631 to limit the position of the fluke 631 .

[0092] When the fluke 631 is opened, the spring applies an elastic force to the locking member 661, causing it to move and extend into the insertion space, and abut against the bottom of the fluke 631 to limit the position of the fluke 631 after it is opened.

[0093] In some embodiments of the present application, a sliding guide structure 690 is provided between the anchor body containing shell 610 and the locking member 661. The sliding guide structure 690 ensures that the locking member 661 is accurately inserted into the insertion space.

[0094] The sliding guide structure 690 includes a long slide groove arranged on the locking member 661 and a guide protrusion arranged on the bottom wall of the anchor body containing shell 610. The guide protrusion is inserted into the long slide groove. When the locking member 661 slides, it slides back and forth along the opening direction of the long slide groove through the cooperation of the long slide groove and the guide protrusion.

[0095] In some embodiments of the present application, the side surface of the fluke 631 and the bottom surface of the fluke 631 are connected by a smoothly transitioning curved surface 633 .

[0096] When fluke 631 is deployed, it rotates from a vertical position to a horizontal position. During this rotation, locking member 661 always abuts against fluke 631, passing from the side of fluke 631 through transition connecting surface 633 to the bottom of fluke 631. During this process, elastic element 663 is always in a compressed state to ensure the normal deployment of fluke 631.

[0097] The transition surface 633 is preferably an arcuate surface. The transition surface 633 between the side and bottom surfaces of the fluke 631 can reduce the friction between the locking component and the fluke 631 when the fluke 631 is rotated to open, so that the fluke 631 can be quickly deployed.

[0098] In some embodiments of the present application, the anchor bracket 620 includes a plurality of connecting plates 621, which are arranged in sequence along the circumference of the anchor body containing shell 610, and an installation space 622 is formed between adjacent connecting plates 621. The fluke 631 is located in the installation space 622 and is hinged to the connecting plates 621 on both sides.

[0099] The connecting plate 621 includes two side plates, and the angle between the two side plates is an acute angle or a right angle. The side plates corresponding to the two adjacent connecting plates 621 are arranged opposite to each other, and the installation space 622 is formed between the two oppositely arranged side plates.

[0100] A rotation shaft is provided in the installation space 622 , and is located near the bottom of the connecting plate 621 . The fluke 631 is rotatably connected to the rotation shaft so as to be hinged relative to the anchor bracket 620 .

[0101] In some embodiments of the present application, a hinge shaft 652 is provided in the installation space 622 , and the fluke limiter 650 is rotatably connected to the hinge shaft 652 .

[0102] A hinge shaft 652 is further provided between the two opposite side plates, and the fluke limiter 650 is rotatably connected to the hinge shaft 652 .

[0103] This embodiment further provides an underwater communication device, including: an upper beacon device 700, the impact force sensing self-release anchor device in the above embodiment, the upper beacon device including:

[0104] An upper section shell 710, and an underwater releaser 720 disposed in the upper section shell;

[0105] The underwater releaser can directly adopt the releaser structure in the existing technology.

[0106] The cable 770 has two ends connected to the anchor limiter and the underwater releaser 720, and has a preset length;

[0107] The depth-fixed release device is connected to the cable buffer device 800 via a connecting rope, and the cable buffer device is connected to the separation column via a connecting rope;

[0108] The depth-fixed release device can adopt the device recorded in the patent document with patent application number: 2020113633525 and patent name: Underwater Cable Deployment Control Device.

[0109] A mounting member 750 is provided on the anchor body containment shell 610 ; the mounting member is a mounting block, which is fixed on the anchor body containment shell 610 .

[0110] The separation column 730 is inserted into the anchor body containment shell 610 through the mounting piece in a direction perpendicular to the side wall of the anchor body containment shell 610, and includes a limiting portion;

[0111] The elastic positioning member 760 is sleeved on the separation column, with one end resting on the mounting member 750 and the other end resting on the limiting portion of the separation column 730;

[0112] The elastic positioning member 760 is an elastic positioning spring, which is used to abut against the limiting portion of the separation column to limit it and prevent it from escaping from the anchor body containing shell.

[0113] When the depth-setting release device is lowered to a predetermined depth, it is separated from the upper beacon device 700 and the anchor device, and the connecting rope between the two is tightened, which simultaneously drives the cable buffer device connected to the connecting rope and the cable between the cable buffer device and the separation column 730 to be tightened. The separation column 730 is separated from the anchor body containment shell 610, so that the upper beacon device 700 and the anchor device are separated.

[0114] When the anchor device sinks to the seabed and separates from the upper beacon device 700, the upper beacon device 700 floats up and the anchor device sinks, eventually causing the cable between the anchor device and the upper beacon device 700 to be tensioned, and the cable drives the fluke limiter to move to the second position to release the limit on the fluke.

[0115] In some embodiments of the present application, the cable buffer device includes a cylinder 810, a piston 820, a lifting ring 830, and a spring 840. The interior of the cylinder is hollow, and the openings at both ends are designed to be equal to the outer diameter of the piston. A stop block 850 is provided at one end of the piston, and a ring 860 is provided at the other end. The cylinder is fixedly connected to the upper end cover of the shell by bolts, and the piston is provided inside the cylinder. One end of the ring extends outward to the upper part of the upper end cover of the shell. The spring is provided inside the cylinder and passes through the piston, with one end resting on the stop block and the other end resting on the end cover of the cylinder. One end of the ring is connected to the connecting rope of the fixed depth release device, and the lifting ring is connected to the lower separation column by a connecting rope.

[0116] After the depth-fixing release device is separated from the upper beacon device 700 and the anchor device 600, the depth-fixing release device moves upward under the action of the upper buoyancy, and the upper beacon device 700 and the anchor device sink due to the gravity of the anchor device. One end of the connecting rope of the depth-fixing release device is connected to the ring end of the cable buffer device. After the cable of the depth-fixing release device is released, the corresponding connecting rope is in a straightened and tensioned state, driving the piston of the cable buffer device to move upward, so that the lower separation column 730 is separated from the anchor body containing shell, so that the upper beacon device 700 is separated from the anchor device.

[0117] Before separation, the anchor device is integrated with the upper beacon device 700 through the separation column 730. After separation, the anchor device is partially connected to the upper beacon device through a cable. One end of the cable is connected to the underwater releaser, and the other end is connected to the anchor rod limiter. The cable is set in the installation space between the anchor device and the upper beacon device, and is wound around the column in the middle of the anchor device. After the separation column is separated from the anchor body containment shell, the upper beacon device continues to move upward under the action of the upper buoyancy, and the anchor device sinks. When the cable is straightened and tensioned, it pulls the anchor claw limiter 650 upward, so that the anchor claw is not fixed and expands outward.

[0118] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
