[0030] In some embodiments of the present application, a water injection anchor is provided, comprising:

[0031] The anchor shell 100 has a receiving cavity 110 formed inside the anchor shell 100.

[0032] The anchor shell 100 constitutes the outer shell of the entire water injection anchor, and the receiving cavity 110 is formed in the hollow inside the anchor shell 100, which can accommodate water when the water injection anchor is deployed.

[0033] In order to reduce the weight of the entire water injection anchor, facilitate transportation and reduce production cost, the anchor shell 100 is made of aluminum alloy.

[0034] The water injection part 120 is formed on the anchor shell 100 and communicates with the accommodating cavity 110.

[0035] The water injection part 120 is a water injection nozzle formed on the anchor shell 100 and mainly used for realizing water injection function. When the water injection anchor is underwater and the water injection part 120 is in an open state, water flow can enter the inside of the accommodating cavity 110.

[0036] When arranged, the water injection part 120 can be arranged at the top surface position of the anchor shell 100, the side surface position of the anchor shell 100 or the bottom position of the anchor shell 100, etc., as long as water injection into the accommodating cavity 110 can be ensured.

[0037] The water injection part 120 can also be arranged in multiple and arranged side by side at the top surface position of the anchor shell 100. When multiple water injection parts 120 are opened at the same time, the effect of rapid water injection can be realized.

[0038] The plugging part 200 is detachably connected to the water injection part 120.

[0039] The plugging part 200 is arranged in a detachable manner connected to the water injection part 120, mainly for facilitating disassembly, so as to facilitate the deployment of the water injection anchor.

[0040] The cable deployment device 300 is arranged in the accommodating cavity 110. The cable deployment device 300 is mainly used for keeping the water injection anchor and the driving mechanism connected when the water injection anchor is separated from the driving mechanism for deploying the water injection anchor, so as to ensure that the water injection anchor moves downward along the set path for deployment and does not change the position from the deployment point due to the action of external force such as buoyancy when completely separated from the driving mechanism, so as to ensure the accurate deployment of the water injection anchor.

[0041] In some embodiments of the present application, the cable deployment device 300 comprises:

[0042] The cable deployment frame 310 is arranged in the anchor shell 100 and fixedly connected to the anchor shell 100.

[0043] The cable deployment drum 320 is rotatably arranged on the cable deployment frame 310. The cable 330 is wound on the cable deployment drum 320. The free end of the cable 330 is connected to the plugging part 200.

[0044] The cable deployment drum 320 can be rotated relative to the cable deployment frame 310 to continuously unwind the cable 330 wound thereon.

[0045] When the water injection anchor is being deployed, the cable 330 can be continuously unwound along the cable deployment drum 320 to separate the water injection anchor from the driving mechanism of the water injection anchor and to increase the distance between the water injection anchor and the driving mechanism, so that the water injection anchor can finally fall into the seabed position.

[0046] When the water injection anchor in the embodiment is not being deployed, such as during transportation or when the water injection anchor is sinking in water but the blocking part 200 is not opened, the blocking part 200 blocks the water injection part 120 to seal the water injection part 120. At this time, the entire accommodating cavity 110 is a sealed cavity and cannot be filled with water. The cable deployment device 300 is correspondingly inside the anchor shell 100 and is connected to the bottom of the blocking part 200.

[0047] When being deployed, the blocking part 200 is driven to separate from the water injection part 120 and to drive the cable 330 to be unwound and deployed. The opening of the blocking part 200 can be achieved by the driving mechanism of the water injection anchor, and the driving mechanism can connect to the blocking part 200 to apply a force to make the blocking part 200 move away from the water injection part 120.

[0048] When being deployed, the water injection anchor sinks in water, and the blocking part 200 is detachably connected to the water injection part 120. A force is applied to the blocking part 200 to make the blocking part 200 open. After the blocking part 200 is opened, the water injection part 120 is opened, and water flows into the accommodating cavity 110 through the water injection part 120 to fill the entire accommodating cavity 110. Under the gravity of the water flow in the anchor shell 100 and the accommodating cavity 110, the entire water injection anchor continuously sinks.

[0049] At the same time, when the blocking part 200 is opened, the cable 330 connected to the blocking part 200 is also taken out of the water injection part 120. At this time, the water injection anchor continuously moves downward, and the cable 330 is continuously unwound. The water injection anchor can be always connected to the driving mechanism through the cable 330, so that the water injection anchor does not deviate from the deployment position during deployment, and the accuracy of the deployment position is ensured.

[0050] In the water injection anchor in the embodiment, the anchor shell 100 is provided, and the water injection part 120 and the blocking part 200 are arranged on the anchor shell 100.

[0051] When the water injection anchor needs to be deployed, the blocking part 200 can be opened to make water flow into the accommodating cavity 110 through the water injection part 120. Under the gravity of the water flow and the gravity of the anchor shell 100 itself, the anchor shell 100 automatically sinks to complete the deployment of the water injection anchor. The water flow is used to assist the deployment, and no additional power is needed. The water injection anchor has a simple structure and is convenient to deploy.

[0052] And, in the water injection anchor sinking and underwater laying process, the cable laying device 300 in the water injection anchor can be automatically unfolded under the action of the self-weight of the water injection anchor to keep the connection with the driving mechanism of the water injection anchor, so that the water injection anchor does not deviate from the laying position in the whole falling process, and the accuracy of the laying position is ensured.

[0053] In some embodiments of the present application, the plugging component 200 comprises:

[0054] a plugging shell 210;

[0055] and a plugging piston 220 installed in the plugging shell 210, and a connecting ring 221 connected with the cable 330 is arranged on the plugging piston 220.

[0056] The plugging piston 220 is inserted into the plugging shell 210 and fixedly connected with the plugging shell 210 through the locking bolt 160.

[0057] The connecting ring 221 is used to connect with the cable 330.

[0058] When not laid, the plugging piston 220 is at least partially inserted into the water injection part 120 and sealingly connected with the water injection part 120. A sealing ring is arranged around the plugging piston 220 and inserted into the water injection hole to keep close connection with the side wall of the water injection hole to achieve the effect of sealing the water injection hole.

[0059] In some embodiments of the present application, the plugging shell 210 is provided with a connecting part for cooperating with the driving mechanism of the laying.

[0060] The connecting part is used to realize the connection with the driving mechanism, and when the driving mechanism acts, it can drive the plugging shell 210 to move linearly up and down to separate the plugging component 200 and the water injection part 120.

[0061] Or it is a linear motion mechanism such as a linear motor or an air cylinder, and the connecting part is a connecting groove or a connecting protrusion, which can be connected with the connecting protrusion or the connecting groove on the linear motor or the air cylinder.

[0062] In some embodiments of the present application, the cable laying rack 310 comprises:

[0063] The connecting rod 311 is arranged along the length direction of the anchor shell 100 and extends to one end of the anchor shell 100 and is fixed with the anchor shell 100;

[0064] The cable laying drum 320 is rotatably connected to the connecting rod 311 through a bearing;

[0065] The support frame 313 is provided with two, which are arranged at the positions of the two ends of the cable laying drum 320, and each support frame 313 is connected to the connecting rod 311 through a group of bolt assemblies.

[0066] Specifically, the bolt assembly includes first locking bolts 314 and second locking bolts 315 symmetrically arranged on both sides of the support frame 313, wherein the first locking bolts 314 are arranged between the cable laying drum 320 end and the support frame 313.

[0067] The first locking bolts 314 and the second locking bolts 315 are screwed and fixed on the connecting rod 311, and the two ends of the first locking bolts 314 and the second locking bolts 315 are respectively abutted on the bearing at both ends of the connecting rod 311 and the end face at both ends of the cable laying drum 320 to limit the cable laying drum 320, preventing the cable laying drum 320 from moving axially along the connecting rod 311.

[0068] The first locking bolts 314 and the second locking bolts 315 of each group cooperate to limit and fix the support frame 313.

[0069] The support frame 313 is arranged with an outer diameter slightly smaller than the inner diameter of the anchor shell 100.

[0070] The support frame 313 is mainly used to support the entire cable laying device 300 to avoid shaking inside the anchor shell 100 during the laying of the cable 330.

[0071] When the cable 330 is laid and expanded, the cable laying drum 320 will be rotated, and since the cable laying drum 320 is connected to the connecting rod 311, the connecting rod 311 is long and has poor stability, and may be shaken up and down by the cable laying drum 320, which may cause the entire cable 330 discharge structure to shake.

[0072] Since the outer diameter of the support rod is slightly smaller than the inner diameter of the anchor shell 100, when the connecting rod 311 shakes up and down, the upper support frame 313 will be supported and abutted on the inner wall of the anchor shell 100, avoiding shaking up and down, and ensuring the stability of the entire cable laying device 300 structure.

[0073] In some embodiments of the present application, the anchor shell 100 includes:

[0074] a shell body 130;

[0075] and a shell plug 140 arranged at one end of the shell body 130, the shell plug 140 being fixedly connected with the shell body 130.
