Description

Technical Field

[0001] The invention belongs to the technical field of underwater deployment equipment, and in particular relates to an improvement of a deployment system and a deployment method for deploying a water injection anchor. Background Art

[0002] The existing anchors used for seabed deployment mainly include gravity anchors. In order to ensure that the gravity anchor can overcome the buoyancy of water and be smoothly deployed to the bottom of the water during deployment, the gravity anchor is usually set to be heavier. When deploying, the anchor cable is connected to the gravity anchor through a release mechanism to lower it for deployment.

[0003] Heavy gravity anchors require a lot of materials, are costly and heavy; Moreover, since the gravity anchor needs to be supported by a release mechanism before being lowered, the release mechanism is mainly an electromagnetic adsorption type release mechanism. Before release, the electromagnet needs to be continuously powered to ensure the load on the gravity anchor. In addition, the gravity anchor is heavy and has a large load, resulting in a large power source and high energy consumption for the release mechanism used to deploy the gravity anchor.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0005] In view of the above technical problems existing in the deployment system in the prior art, the present invention proposes a new deployment system and deployment method, which has a simple structure, is convenient for deployment and has low energy consumption.

[0006] In order to achieve the above invention / design purpose, the present invention adopts the following technical solutions: A deployment system, comprising: A release device, the release device comprising: The support body; The driving device is fixed on the bracket body and includes: a release element having a locked position, a first unlocked position, and a second unlocked position; A driving element, driving the release element to move; And water injection anchor, including: The anchor body has a receiving cavity formed inside and a water injection portion communicating with the receiving cavity formed on the upper side; A cable laying device is arranged in the accommodating cavity and has a cable wound around it; A plugging component, detachably connected to the water injection portion, connected to the release element and the cable; When the release element is in the locking position, the release element limits the blocking component so that it is inserted into the sealing anchor body in the water injection part; When the release element is in the first unlocking position, the release element drives the blocking component to move and separate from the water injection part, and the cable connected to the blocking component remains connected to the water injection anchor; When the release element is in the second unlocking position, the release element is separated from the blocking component.

[0007] Compared with the prior art, the advantages and positive effects of the present invention are: The deployment system of the present invention is provided with a water-injected anchor structure, and the water flow is used as the weight of the anchor deployment, thereby reducing the weight of the anchor itself, reducing the material consumption, and reducing the production cost; At the same time, a release device for matching the water injection anchor is provided. The release device is connected to the water injection anchor before release and ensures the sealing of the water injection anchor. After release, the connection with the anchor body can be ensured by the cable of the water injection anchor, so that the anchor body can fall to the deployment point according to the set route through the limit of the cable when released, so as to achieve accurate deployment with high reliability. During the entire deployment process, the fully automatic deployment of the anchor body and the separation from the anchor body after deployment can be achieved by switching the release element between the locking position, the first unlocking position and the second unlocking position. The deployment method is simple, practical and efficient. During deployment, the release element only needs to be powered on to consume power when it switches from the locked position to the first unlocked position and from the first unlocked position to the second unlocked position. No continuous power supply is required, and the energy consumption is low.

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0014] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In the description of the implementation method, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0015] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0016] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0017] In some embodiments of the present application, a deployment system is proposed, comprising: A release device, the release device comprising: The support body 100; The driving device is fixed on the bracket body 100 and includes: A release element 200 having a locked position, a first unlocked position and a second unlocked position; The driving element 300 drives the release element 200 to operate.

[0018] The support and fixation of the driving element 300 is achieved by the bracket body 100. The driving element 300 is mainly used to provide power for the release element 200 to move. When the driving element 300 drives the release element 200 to move, the release element 200 can be switched between the locked position, the first unlocked position and the second unlocked position.

[0019] In some embodiments of the present application, the deployment system includes a water injection anchor, and the water injection anchor includes: The anchor body 600 has a receiving cavity 610 formed therein, and a water injection portion 620 communicating with the receiving cavity 610 is formed on the anchor body 600 .

[0020] The anchor body 600 constitutes the outer shell of the entire water injection anchor, and its interior is hollow to form a receiving chamber 610, which can receive water when the water injection anchor is deployed.

[0021] In order to reduce the weight of the entire water injection anchor, facilitate transportation and reduce production costs, the anchor body 600 is made of aluminum alloy.

[0022] The water injection part 620 is a water injection nozzle formed on the anchor body 600, which is mainly used to realize the water injection function. It is connected with the accommodating cavity 610. When the water injection anchor is underwater and the water injection part 620 is in an open state, water can flow into the accommodating cavity 610.

[0023] During setting, the water injection part 620 can be formed at the top surface of the anchor body 600. When the water injection part 620 is opened, water will continuously flow into the accommodating cavity 610 through the water injection part 620, filling the entire accommodating cavity 610. Under the gravity of the water flow in the anchor body 600 and the accommodating cavity 610, the entire water-injected anchor will continue to sink.

[0024] The cable laying device 800 is disposed in the accommodating cavity 610 , and a cable 830 is wound around the cable laying device 800 .

[0025] The cable 830 wound around the cable laying device 800 can be continuously deployed when the water-injection anchor is filled with water and sinks.

[0026] The blocking component 700 is detachably connected to the water injection portion 620 , and is connected to the release element 200 and the cable 830 .

[0027] The sealing component 700 is arranged at the water injection part 620 to realize the opening and closing of the water injection part 620. When it is connected to the water injection part 620, it seals the entire accommodating chamber 610. When it is separated from the water injection part 620, water can flow from the water injection part 620 into the accommodating chamber 610.

[0028] The blocking component 700 is connected to the release element 200. When the driving element 300 is actuated, the release element 200 can be driven to actuate, thereby driving the blocking component 700 connected thereto to move, so as to separate from the water injection portion 620, thereby achieving the effect of opening the water injection portion 620.

[0029] The blocking component 700 is connected to the cable 830. When the release element 200 is driven by the force of the driving element 300 to separate the blocking component 700 from the water injection part 620, the cable 830 connected to the blocking component 700 can ensure the connection between the anchor device and the release device, so that the anchor device can be sunk and deployed according to the set path.

[0030] When the release element 200 is in the locking position, the release element 200 limits the blocking component 700 so that it is inserted into the water injection portion 620 to seal the anchor body 600; When the release element 200 is in the first unlocking position, the release element 200 drives the blocking component 700 to move and separate from the water injection portion 620, and the cable 830 connected to the blocking component 700 remains connected to the water injection anchor; When the release element 200 is in the second unlocking position, the release element 200 is separated from the blocking component 700, and the blocking component 700 and the water injection anchor are separated from the release device.

[0031] Specifically, when the water injection anchor is not deployed, the sealing component 700 is inserted into the water injection part 620 of the water injection anchor to seal the water injection anchor. The sealing component 700 seals the water injection part 620 and connects the water injection anchor and the release device as a whole. The release device is assembled on the bracket body 100, and the weight of the water injection anchor is borne by the bracket body 100.

[0032] When the water injection anchor is deployed, the driving element 300 is controlled to move, driving the release element 200 to move, and the release element 200 moves along the first direction to the first unlocking position.

[0033] When the release element 200 moves from the locking position to the first unlocking position, it drives the blocking component 700 to move away from the water injection portion 620 .

[0034] When moving to the first unlocking position, the release element 200 drives the sealing component 700 to move and separate from the water injection part 620. The water injection part 620 opens, water enters the anchor body 600, and the anchor body 600 sinks. When the anchor body 600 sinks, the sealing component 700 and the releasing device are integrated, and the cable 830 connected to the sealing component 700 is continuously unfolded to maintain the connection between the releasing device and the anchor body 600, ensuring that the anchor body 600 moves downward along the set path for deployment, and will not change its position and deviate from the deployment point due to the action of external forces such as buoyancy due to complete separation from the driving mechanism, thereby ensuring the precise deployment of the water-injected anchor.

[0035] The anchor body 600 will continue to sink and fall to the deployment position at the bottom of the water. After the anchor body 600 falls to the deployment position, there is no need to keep the anchor body 600 and the release device connected.

[0036] At this time, the driving element 300 can be controlled to continue to move, and then drive the release element 200 to move to the second unlocking position. When the release element 200 moves from the first unlocking position to the second unlocking position, it moves along the second direction, wherein the second direction is opposite to the first direction, and drives the blocking component 700 to move away from the release element 200.

[0037] When the release element 200 moves to the second unlocking position, the release element 200 is separated from the blocking component 700. At this time, the blocking component 700, the anchor body 600 and the cable 830 are integrated and laid on the bottom of the water.

[0038] The water injection anchor structure of this embodiment uses water flow as the weight of the anchor, which reduces the weight of the anchor itself, reduces the material used, and reduces the production cost; At the same time, a release device for matching the water injection anchor is provided. The release device is connected to the water injection anchor before release and ensures the sealing of the water injection anchor. After release, the connection with the anchor body 600 can be ensured by the cable 830 of the water injection anchor, so that the anchor body 600 can fall to the deployment point according to the set route through the limit of the cable 830 when released, so as to achieve accurate deployment; During the entire deployment process, the anchor body 600 can be fully automatically deployed and separated from the anchor body 600 after deployment by switching the release element 200 between the locking position, the first unlocking position and the second unlocking position. The deployment method is simple, the deployment efficiency is high, and the deployment accuracy is good.

[0039] In some embodiments of the present application, the water injection anchor includes: The fluke 900 is connected to the bottom of the anchor body 600 .

[0040] There are two flukes 900 , which are symmetrically arranged at both ends of the anchor body 600 , and are connected to both ends of the anchor body 600 via connecting ropes 930 . A connecting ring 721 is provided at the connection between the connecting rope 930 and the fluke 900 .

[0041] Two connecting ropes 930 are provided, one of which is wound around one end of the anchor body 600 along the circumference of the anchor body 600 and extends downward to form a connecting section; The other one is wound around the other end of the anchor body 600 along the circumference of the anchor body 600 and extends downward to form a connecting section; The two flukes 900 are connected to the two connecting sections respectively to realize the connection between the flukes 900 and the anchor body 600 .

[0042] The connecting ring 721 connected to the fluke 900 and the connecting rope allows the fluke 900 to rotate freely relative to the connecting rope, so that the fluke 900 has freedom in multiple directions, so that the fluke 900 can be quickly anchored.

[0043] In some embodiments of the present application, the fluke 900 includes an anchor rod 910 and an arc-shaped claw body 920 connected to the end of the anchor rod 910 . A plurality of arc-shaped claw bodies 920 are provided and arranged circumferentially along the anchor rod 910 .

[0044] The arc-shaped claw body 920 can be firmly hooked into the bottom of the water when it falls into the bottom mud. A plurality of arc-shaped claw bodies 920 are arranged circumferentially along the anchor rod 910, so that when the anchor claw 900 falls into the bottom of the water and anchors, it can be firmly anchored to the bottom mud no matter from which angle it falls.

[0045] When the water-injected anchor is deployed, its water-injection part 620 is opened, water enters into the accommodating chamber 610, and the water-injected anchor sinks under the gravity of the anchor body 600 and the water flow. At the same time, the anchor claws 900 connected above it extend to both sides of the water-injected anchor under the impact force of the water flow. When the water-injected anchor falls to the bottom of the deployed water, the arc-shaped claw bodies 920 located on both sides of it can be stuck into the bottom of the water to be firmly anchored at the deployment position. Through the cooperation of the water-injected anchor and the anchor claws 900, the water-injected anchor can be accurately and firmly deployed.

[0046] A guide portion 134 is formed inside the bracket body 100; The driving element 300 is configured to: drive the release element 200 to switch between the locking position and the first unlocking position; A locking assembly, used to limit and fix the anchor claw 900; The transmission member 400 is movably disposed in the guide portion 134 and contacts and cooperates with the release element 200 to unlock or lock the locking assembly; When the release element 200 is in the locking position, the release element 200 limits the transmission member 400, and the transmission member 400 locks the locking assembly to limit and fix the fluke 900; When the release element 200 is in the first unlocking position, the transmission member 400 moves toward the release element 200 and unlocks the locking assembly to release the position restriction of the fluke 900 .

[0047] When the driving element 300 drives the releasing element 200 to move, the releasing element 200 can be switched between the locking position and the first unlocking position.

[0048] When the release element 200 is in the locking position, the release element 200 is not only connected to the blocking component 700, so that the blocking component 700 is inserted into the water injection part 620 to seal the anchor body 600, but also the release element 200 cooperates with the transmission member 400 at the same time to limit the transmission member 400. After the transmission member 400 is limited, the transmission member 400 limits the locking assembly to ultimately limit the fluke 900.

[0049] When the release element 200 is in the first unlocking position, it is not only separated from the blocking component 700, but also linked with the transmission member 400 to unlock the limit of the transmission member 400, so that the transmission member 400 unlocks the locking assembly, thereby releasing the limit of the fluke 900.

[0050] The release device in this embodiment can separate the release element 200 from the anchor body 600 connected thereto when the release element 200 is driven from the locking position to the first unlocking position, thereby achieving the deployment of the anchor body 600; When the release element 200 moves from the locking position to the first unlocking position, it can also link the transmission member 400 and the locking assembly in contact with it to move, so that the locking assembly is separated from the fluke 900, and the fluke 900 is deployed. The release element 200 and the locking assembly are simultaneously driven by the action of a driving element 300, so that the anchor body 600 and the fluke 900 are released synchronously, thereby improving the release efficiency. Furthermore, when releasing, the power consumption is only the power required for the driving element 300 to drive the release element 200 to rotate from the locked position to the first unlocked position. Compared with the existing electromagnetic adsorption release mechanism, it does not require continuous power supply and consumes less power.

[0051] In some embodiments of the present application, a clamping portion 143 is formed in the bracket body 100; The locking assembly includes: a locking component 500 rotatably connected to the bracket body 100 , one end of which is disposed in the clamping portion 143 , and the other end of which is in contact with and cooperates with the transmission member 400 .

[0052] The carrying rope includes a lifting ring at one end thereof. The end of the carrying rope without the lifting ring is fixed to the bracket body 100, and the end with the lifting ring is wound along the bottom of the anchor body 600 to a position close to the locking component 500 and hung on the locking component 500 through the lifting ring to limit the anchor claw 900 at the bottom of the anchor body 600.

[0053] The anchor claw 900 connected to the bottom of the anchor body 600 can be limited and fixed by the cooperation of the carrying rope and the locking component 500.

[0054] In some embodiments of the present application, the release element 200 is a release rod, the transmission member 400 is a transmission rod, and its contact end with the locking component 500 is an arcuate surface 410, and the locking component 500 is provided with an arcuate groove 510 that cooperates with the arcuate surface 410.

[0055] When the release element 200 is in the locked position, the arc surface 410 end of the transmission member 400 is inserted into the arc groove 510. The structural coordination of the arc surface 410 and the arc groove 510 not only ensures that the two can be locked firmly, but also facilitates the separation of the transmission member 400 and the release element 200.

[0056] When the release element 200 is in the locking position, the transmission member 400 is restrained against the release element 200 , the transmission member 400 is in contact with the locking member 500 to restrain one end of the locking member 500 , and the other end of the locking member 500 is restrained by the clamping portion 143 .

[0057] At this time, one end of the carrying rope is fixed to the bracket body 100, and the other end passes around the anchor claw 900 from the bottom and is carried on the locking component 500 through the lifting ring. Both ends are fixed, and the anchor claw 900 is supported and limited by the locking component 500 in cooperation with the carrying rope.

[0058] The locking component 500 is rotatably connected to the bracket body 100. When the release element 200 is in the unlocked position, the transmission member 400 is separated from the locking component 500. At this time, the locking component 500 will rotate along the bracket body 100 under the weight of the carrying rope and the anchor claw 900, and then disengage from the clamping portion 143. The lifting ring will disengage from the locking component 500, and one end of the lifting ring of the carrying rope will slide down. The carrying rope no longer carries the anchor claw 900, and the limit on the anchor claw 900 is eliminated, so that the anchor claw 900 is released and opened, and the deployment is completed.

[0059] In some embodiments of the present application, the release element 200 includes a main body 210 and a protrusion 220 formed from the main body 210; When the release element 200 is in the locked position, the transmission member 400 abuts against the protrusion 220; When the release element 200 is in the first unlocking position, the transmission member 400 abuts against the main body 210 .

[0060] When the release element 200 is driven, its position changes. When the position of the release element 200 changes, the contact position between the release element 200 and the transmission member 400 also changes.

[0061] When the transmission member 400 and the protrusion 220 are in contact and matched, the protrusion 220 of the protruding main body 210 can be used to abut and fix it to achieve a limiting effect. When the transmission member 400 is limited, it can remain against the locking member 500 to limit the locking member 500.

[0062] At the same time, the blocking component 700 is connected to the release element 200 , and the release element 200 is connected to the support body 100 through the driving element 300 . The weight of the water injection anchor is borne by the support body 100 , and the fluke 900 is borne by the locking component 500 .

[0063] If the release element 200 is switched to the unlocking position, the transmission member 400 contacts the main body 210. Since the contact position between the transmission member 400 and the release element 200 slides from the protrusion 220 to the main body 210, the transmission member 400 moves along the guide portion 134 toward the main body 210. When the transmission member 400 is close to the main body 210, it will be away from the locking component 500, thereby separating from the locking component 500. The locking component 500 is no longer limited, and the locking component 500 rotates to disengage from the clamping portion 143 to separate from the fluke 900.

[0064] The cross-sectional shape of the main body 210 can be square, circular or polygonal, and the protrusion 220 can be connected to the side wall of the main body 210. In order to facilitate the smooth sliding of the transmission member 400 between the protrusion 220 and the main body 210, the protrusion 220 and the main body 210 are arranged to be smoothly transitionally connected. At the same time, the outer side surface of the protrusion 220 is arranged to be a smooth curved surface.

[0065] In some embodiments of the present application, the protrusion 220 is semicircular and the body 210 is rectangular.

[0066] In some embodiments of the present application, the driving element 300 is a rotation driving mechanism for driving the release element 200 to rotate, and the protrusions 220 are arranged along the circumference of the body 210 .

[0067] The rotation driving mechanism is a rotation motor, and the protrusion 220 and the main body 210 are smoothly connected.

[0068] When the release element 200 rotates circumferentially, the transmission member 400 switches positions between the protrusion 220 and the body 210; The blocking component 700 is provided with a groove, and an internal thread is provided in the groove.

[0069] In some embodiments of the present application, the blocking component 700 includes: Sealing shell 710; And a blocking piston 720 installed in the blocking shell 710 , on which a connecting ring 721 connected with the cable 830 is provided.

[0070] A sealing ring is provided on the blocking piston 720 for sealingly connecting with the water injection part.

[0071] The blocking piston 720 is inserted into the blocking shell 710 and fixedly connected to the blocking shell 710 via locking bolts.

[0072] The sealing shell 710 is provided with a groove and an internal thread.

[0073] A threaded fitting portion 230 that fits with the internal thread of the release element 200 is provided at the bottom of the release element 200 . The threaded fitting portion 230 is an external thread. The release element 200 can be screwed into the internal thread of the groove through the threaded fitting portion 230 to achieve threaded connection with the blocking component 700 .

[0074] The support body 100 is provided with a rotation limiting portion 110 which cooperates with the blocking component 700 to limit the linear movement of the blocking component 700 .

[0075] The rotation limiting portion 110 is a linear limiting groove or a linear limiting protrusion, which is used to cooperate with the blocking component 700. Accordingly, a linear limiting protrusion or a linear limiting groove that cooperates with the linear limiting groove or the linear limiting protrusion is provided on the blocking component 700.

[0076] When the rotary motor rotates, it will drive the release element 200 to rotate, and then drive the sealing component 700 that cooperates with its thread to make a spiral linear movement. Due to the rotation limit part 110 set on the bracket body 100, the rotation of the sealing component 700 is limited so that it can only move up and down linearly along the release element 200. When the sealing component 700 moves up and down, it can be separated from the water injection part 620, so that the sealing component 700 no longer blocks the water injection part 620. At this time, the water flow can enter the interior of the anchor body 600 through the water injection part 620, causing the anchor body 600 to sink.

[0077] In some embodiments of the present application, the bracket body 100 includes: The hanging bracket 120 includes a transverse main body and side wall parts connected to both sides of the transverse main body. The side wall parts are arranged obliquely, and a connecting part is formed at the end of each side wall part, and the connecting part is a connecting flange.

[0078] A hoisting portion is provided on the transverse main body portion, and the hoisting portion is a hoisting hole, which facilitates hoisting of the entire hoisting bracket 120 .

[0079] The connecting bracket 140 is connected to the hanging bracket 120 , and the clamping portion 143 is formed on the connecting bracket 140 .

[0081] The guide portion 134 is a guide groove formed in the guide bracket 130, and is used to guide and limit the movement of the transmission member 400 placed therein.

[0082] In some embodiments of the present application, the guide bracket 130 includes: The first guide frame 131 has an accommodation portion 133 formed therein. The accommodation portion 133 is disposed through the first guide frame 131 along a height direction of the first guide frame 131 .

[0083] The receiving portion 133 is used to receive the release element 200 . The release element 200 connected to the drive element 300 is arranged in the receiving portion 133 and its bottom protrudes from the receiving portion 133 .

[0087] The two second guide frames 132 are respectively inserted into the connecting frames 140 at both ends of the hanging frame 120 and are connected and fixed to the connecting frames 140 .

[0088] The guide portion 134 is formed between each of the first guide frame 131 and the second guide frame 132 , and the guide portion 134 is connected to the accommodating portion 133 , so that the transmission member 400 located in the guide portion 134 can extend into the accommodating portion 133 to cooperate with the release element 200 in the accommodating portion 133 .

[0089] In some embodiments of the present application, there are two transmission members 400, which are symmetrically arranged in two guide portions 134 on both sides of the release element 200, and are in contact and cooperation with both sides of the release element 200. The corresponding release element 200 is provided with two protrusions 220 to respectively contact and cooperate with the two transmission members 400.

[0090] Two locking components 500 are provided, which are arranged in the two connecting brackets 140 and cooperate with the two transmission members 400 respectively.

[0091] By providing two transmission members 400 and a locking member 500 cooperating with the two transmission members 400, the placement auxiliary members at both ends of the main placement member can be limited at the same time. When the release element 200 is actuated, the two transmission rods and the locking member 500 can be driven to act synchronously, thereby achieving synchronous release of the two placement auxiliary members at both ends of the main placement member, thereby ensuring the consistency of the release.

[0092] The driving element 300 is disposed in a sealed cabin 310 , which is composed of an outer cabin shell and an end cover fixedly connected to the outer cabin shell. The end cover is fixedly connected above the guide bracket 130 to achieve the connection between the sealed cabin 310 and the guide bracket 130 .

[0093] A watertight connector is provided at the bottom of the sealed cabin 310, and the driving element 300 is activated by connecting the connector to the watertight connector and supplying electricity.

[0094] In some embodiments of the present application, the accommodating portion 133 includes a first accommodating space 1331 , a second accommodating space 1332 , and a third accommodating space 1333 which are sequentially arranged from top to bottom along the height direction of the guide bracket 130 .

[0095] The release element 200 is disposed through the first accommodating space 1331 , the second accommodating space 1332 and the third accommodating space 1333 , and a bearing assembly is mounted above the release element 200 .

[0096] A first limiting step portion 240 and a second limiting step portion 250 are formed on the release element 200 .

[0097] The first bearing 260 is sleeved on the release element 200 and is assembled in the first accommodating space 1331 . Both ends of the first bearing 260 are limited by the first limiting step 240 and the end cover respectively.

[0098] The protrusion 220 is located in the second accommodation space 1332 .

[0099] The second bearing 270 is sleeved on the release element 200 and is located in the third accommodating space 1333 . A limiting platform is formed in the third accommodating space 1333 . Both ends of the second bearing 270 are limited by the second limiting step portion 250 and the limiting platform.

[0100] The first bearing 260 and the second bearing 270 enable the release element 200 to rotate relative to the guide bracket 130 .

[0101] In some embodiments of the present application, the connection bracket 140 is formed with: A first cavity 144 with an opening on one side, wherein the first cavity 144 is in communication with the guide portion 134; and The second cavity 145 , in which the locking component 500 is disposed.

[0102] The transmission member 400 extends through the guide portion 134 into the first cavity 144 and then extends from the first cavity 144 into the second cavity 145 to abut against the locking member 500 in the second cavity 145 .

[0103] In some embodiments of the present application, the release mechanism also includes an elastic element 430, which is arranged in the first cavity 144 and the guide portion 134, with one end abutting against the wall of the first cavity 144 opposite to the opening, and the other end abutting against the abutment protrusion 420 of the transmission member 400.

[0104] When the transmission member 400 is in the locking position, the elastic element 430 is compressed between the abutting protrusion 420 and the wall surface of the first cavity 144 , and undergoes elastic deformation.

[0105] When the transmission member 400 is in the unlocked position, the transmission member 400 moves to a side away from the locking member 500, and the elastic element 430 recovers its deformation and applies a reverse elastic force to the transmission member 400, so that it is quickly separated from the locking member 500.

[0106] In some embodiments of the present application, the connecting bracket 140 includes: a bracket body 141 and a limiting element 142 fixed on the bracket body 141, and the clamping portion 143 is a clamping groove formed on the limiting element 142, and the bottom of the clamping groove is open.

[0107] When the release element 200 is in the locking position, the transmission member 400 abuts against one end of the locking component 500 to limit it, and the other end of the locking component 500 is clamped in the clamping groove with a bottom opening and is limited by the top wall of the clamping groove.

[0108] After the transmission member 400 unlocks the position limit of the locking component 500 , the locking component 500 rotates out of the opening under the action of the fluke 900 and separates from the clamping portion 143 .

[0109] In some embodiments of the present application, a fixing bracket 160 is fixedly connected below the connecting bracket 140, and an arc-shaped clamping portion 143 is formed on the fixing bracket 160 for clamping on the main deployment component to limit the main deployment component to prevent the main deployment component from shaking around during deployment and affecting the deployment effect.

[0110] In some embodiments of the present application, vias 161 are symmetrically provided on the fixing bracket 160; One end of the carrying rope is fixed to one of the through holes 161 , and the other end passes through the other through hole 161 and is hung on the locking component 500 through a hanging ring at the end thereof.

[0111] In some embodiments of the present application, the cable laying device 800 includes: a cable laying frame 810 fixedly connected to the anchor body 600; The cable laying drum 820 is rotatably disposed on the cable laying frame 810 , and the cable 830 is wound around the cable laying drum 820 .

[0112] The cable laying drum 820 can be rotated relative to the cable laying frame 810 to continuously unfold the cable 830 wound thereon.

[0113] When the water injection anchor is deployed, the cable 830 can be continuously opened by rotating along the cable deployment tube 820, so that the water injection anchor and the driving mechanism for deploying the water injection anchor are separated and the distance between them becomes larger and larger, so that the water injection anchor can finally fall to the seabed.

[0114] In some embodiments of the present application, the cable laying rack 810 includes: A connecting rod 811 is arranged along the length direction of the anchor body 600 and extends to one end of the anchor body 600 to be fixed to the anchor body 600; The cable laying drum 820 is rotatably connected to the connecting rod 811 via a bearing; There are two support frames 813 , which are arranged at two ends of the cable laying drum 820 , respectively. Each support frame 813 is connected to the connecting rod 811 through a set of bolt assemblies.

[0115] In the specific configuration, the bolt assembly includes a first locking bolt 814 and a second locking bolt 815 symmetrically arranged on both sides of the support frame 813 , wherein the first locking bolt 814 is arranged between the end of the cable laying barrel 820 and the support frame 813 .

[0116] The first locking bolt 814 and the second locking bolt 815 are both screwed and fixed on the connecting rod 811. The end faces of the two first locking bolts 814 at both ends respectively abut against the bearings at both ends of the connecting rod 811 and the end faces of the cable laying cylinder 820 at both ends to limit the cable laying cylinder 820 and prevent the cable laying cylinder 820 from moving axially along the connecting rod 811.

[0117] The support frame 813 is fixed in position by the cooperation of the first locking bolt 814 and the second locking bolt 815 of each group.

[0118] When the support frame 813 is set, the maximum outer diameter of the support frame 813 is slightly smaller than the inner diameter of the anchor body 600.

[0119] The support frame 813 is mainly used to play a supporting role to prevent the entire cable laying device 800 from shaking inside the anchor body 600 when the cable 830 is laid.

[0120] When the cable 830 is deployed, the cable deploying drum 820 will be driven to rotate. Since the cable deploying drum 820 is rotatably connected to the connecting rod 811, the connecting rod 811 is a long rod with poor stability and may be driven by the cable deploying drum 820 to swing up and down inside the anchor body.

[0121] Since the outer diameter of the support rod is slightly smaller than the inner diameter of the anchor body 600, when the connecting rod 811 swings up and down, the support frame 813 will be supported against the inner wall of the anchor body 600 to avoid swinging up and down, thereby ensuring the stability of the entire cable laying device 800 structure.

[0122] In some embodiments of the present application, the anchor body 600 includes: Shell body 630; And a shell plug 640 is arranged at one end of the shell body 630 , and the shell plug 640 is fixedly connected to the shell body 630 .

[0123] To ensure the sealing of the anchor body 600, the shell plug 640 and the shell body 630 may be fixed together by welding.

[0124] The shell end cover 650 is arranged at the other end of the shell body 630 , is locked and fixed to the shell body 630 by locking bolts and is fixedly connected to the connecting rod 811 .

[0125] In some embodiments of the present application, the shell end cover 650 includes an extension portion 651 formed at its end, the extension portion 651 is inserted into the shell body 630, the extension portion 651 and the shell body 630 are connected by a locking bolt, and a sealing structure is arranged between the extension portion 651 and the shell body 630.

[0126] The sealing structure includes a sealing strip on the shell end cover 650, which is squeezed between the extension portion 651 and the inner wall of the shell body 630 to achieve sealing between the two and prevent water from entering.

[0127] In some embodiments of the present application, the connecting rod 811 is connected to the shell end cover 650 via a connecting piece 840, the connecting piece 840 fits the shell end cover 650 and is locked and fixed to the shell end cover 650, and a pressing piece 850 is arranged on the connecting rod 811 to press and fix the connecting piece 840.

[0128] The connecting piece 840 is a connecting plate, which fits the end surface of the shell end cover 650 and is fixedly connected to the shell end cover 650 by locking screws. The connecting rod 811 is screwed into the connecting piece 840 to achieve connection with the shell end cover 650 through the connecting piece 840.

[0129] The clamping member 850 is a clamping nut, which can be screwed onto the connecting rod 811 and pressed onto the connecting member 840 to clamp and limit the connecting member 840 .

[0130] In some embodiments of the present application, both ends of the anchor body 600 are arc-shaped curved surfaces 410 with smooth transitions.

[0131] The structural manner of arranging the two ends of the anchor body 600 into arc-shaped curved surfaces 410 can reduce the resistance encountered by the anchor body 600 during the falling process, so that the water injection anchor can be quickly dropped and deployed.

[0132] The present invention proposes a deployment method based on the deployment system described in the above embodiment, comprising the following steps: The driving element 300 is controlled to be powered on and actuated, and the release element 200 is driven to move by the driving element 300, so that the release element 200 is switched from the locking position to the first unlocking position, and the driving element 300 is controlled to be powered off after reaching the first unlocking position; After power failure, the sealing component 700 is driven by the release element 200 to separate from the water injection part 620, and the cable 830 is driven by the sealing component 700 to be pulled out of the water injection part 620. Water enters the water injection anchor from the water injection part 620, and the water injection anchor sinks and is deployed under the action of the water flow and the deadweight of the water injection anchor. During the sinking process of the water injection anchor, the cable 830 is connected between the sealing component 700 and the water injection anchor.

[0133] The transmission member 400 releases the limit of the locking assembly, the limit of the anchor claw 900 is eliminated, the anchor claw 900 is in an open state and sinks with the water-injected anchor; After the driving element 300 drives the release element 200 to rotate from the locking position to the first unlocking position, the power is cut off, thereby avoiding continuous power supply to the release element 200 and reducing power loss.

[0134] When the release element 200 rotates from the locked position to the first unlocked position, the release element 200 rotates along the first direction to drive the blocking component 700 to move linearly away from the water injection portion 620, that is, to move linearly upward, so that the blocking component 700 escapes from the water injection portion 620.

[0135] After the release element 200 is in the first unlocking position, the blocking component 700 is separated from the water injection part 620 of the water injection anchor, and the interior of the water injection anchor is automatically filled with water for deployment. At the same time, the release element 200 automatically unlocks the transmission member 400, and the transmission member 400 is linked to unlock the locking assembly, so that the anchor claw 900 of the water injection anchor is also released and opened for deployment.

[0136] After the preset time, check whether the water injection anchor is in place. The control driving element 300 is powered on and moves in the reverse direction to switch from the first unlocking position to the second unlocking position, so that the blocking component 700 and the release device are separated.

[0137] A depth sensor can be set up to detect and feedback whether the water injection anchor is deployed in place.

[0138] After the water injection anchor is deployed in place, the driving element 300 can be controlled to be powered on again to rotate in the second direction, which is opposite to the first direction. At this time, the release element 200 is driven to rotate in the opposite direction, and at the same time drives the blocking component 700 to move downward in a straight line. When the release element 200 rotates to the second unlocking position, it separates from the release element 200, thereby achieving complete separation of the blocking component 700 and the anchor body 600 from the release device.

[0139] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
