[0049] The support shaft 10 is arranged along the longitudinal direction, and the support shaft 10 is fixedly connected to the hull 90 .

[0050] The number of the release links 20 is two, and the two release links 20 are arranged on both lateral sides of the support shaft 10; the release link 20 includes a bearing portion 21, an L-shaped connecting portion 22 and an L-shaped supporting portion 23, the two L-shaped connecting portions 22 are arranged back to back and rotatably connected to the support shaft 10, the two L-shaped supporting portions 23 are arranged face to face, and the top end of the L-shaped supporting portion 23 is fixedly connected to the bottom end of the L-shaped connecting portion 22, and the bearing portion 21 is fixedly connected to the top end of the L-shaped connecting portion 22.

[0051] There are two compression springs 30 , which are installed between the bearing portion 21 and the hull 90 . The elastic force of the compression spring 30 on the bearing portion 21 can drive the two L-shaped support portions 23 away from each other.

[0052] There are two ballasts 40 , which are placed one by one on the support portion 21 , and the gravity of the ballasts 40 on the support portion 21 can drive the two L-shaped support portions 23 to approach each other.

[0053] The lifting mechanism 50 is fixedly connected between the ballast 40 and the hull 90 and is used to drive the ballast 40 to rise and fall.

[0054] The attitude sensing module 60 is fixedly installed inside the gravity penetration anchor 80 and is used to obtain real-time attitude information of the gravity penetration anchor 80 .

[0055] The terminal control module 70 is connected to the posture sensing module 60 and the lifting mechanism 50 via electrical signals, and the terminal control module 70 can control the lifting mechanism 50 to drive the ballast 40 to move up and down according to real-time posture information.

[0056] The present application adopts an automatic delivery method, in which the snap plate 82 of the gravity penetration anchor 80 is vertically limited by two L-shaped support parts 23 arranged face to face, and the two L-shaped connecting parts 22 arranged back to back and rotatably connected to the support shaft 10 are driven, and the ballast 40 and the compression spring 30 are used to drive the two L-shaped support parts 23 to move away from or close to each other, thereby realizing the support and fixation and automatic delivery of the gravity penetration anchor 80, realizing the unmanned delivery operation of the gravity penetration anchor 80, shortening the delivery time of the gravity penetration anchor 80, improving the stability and reliability of the delivery of the gravity penetration anchor 80, simplifying the delivery link, shortening the delivery process, and thereby improving the delivery accuracy of the gravity penetration anchor 80.

[0057] It should be noted that in this application, the lateral direction refers to Figure 1 The left and right directions in the vertical direction refer to Figure 1 Vertical to the paper direction.

[0058] Specific embodiment 1, as Figure 1-Figure 5 As shown, a gravity penetration anchor automatic release device includes: a support shaft 10, a release link 20, a compression spring 30, a ballast 40, a lifting mechanism 50, a posture sensing module 60 and a terminal control module 70.

[0059] The support shaft 10 is arranged along the longitudinal direction, and both ends of the support shaft 10 are fixedly connected to the hull 90 .

[0060] There are two release links 20 , and the two release links 20 are arranged on both lateral sides of the support shaft 10 in a one-to-one correspondence, that is, one release link 20 is arranged on the left side of the support shaft 10 , and the other release link 20 is arranged on the right side of the support shaft 10 .

[0061] Each release link 20 includes a load-bearing portion 21, an L-shaped connecting portion 22 and an L-shaped supporting portion 23 that are fixedly connected in sequence. The two L-shaped connecting portions 22 are arranged back to back and are rotatably connected to the support shaft 10, that is, the lateral spacing of the bending parts of the two L-shaped connecting portions 22 is smaller than the lateral spacing of the two ends of the L-shaped connecting portions 22, so that the two L-shaped connecting portions 22 are connected to the support shaft 10 to form an X-shape as a whole; the two L-shaped supporting portions 23 are arranged face to face, and the L-shaped supporting portions 23 include a vertical section 24 and a horizontal section 25 that are fixedly connected. The entirety of 25 is arc-shaped, and a receiving groove 26 for receiving the snap plate 82 is formed on the horizontal section 25. The bottom surface of the receiving groove 26 is a conical surface. The top end of the vertical section 24 is fixedly connected to the bottom end of the L-shaped connecting portion 22, and the bottom end of the vertical section 24 is fixedly connected to the horizontal section 25. The lateral spacing between the top ends of the two L-shaped supporting portions 23 is greater than the lateral spacing between the bottom ends, so that the two L-shaped supporting portions 23 in the closed state can vertically support and fix the snap plate 82 at the tail end of the gravity penetration anchor 80 between the two vertical sections 24.

[0062] Preferably, the ratio of the effective lever arm lengths of the release links 20 on the upper and lower sides of the support shaft 10 is greater than 5, so as to utilize the lever principle to improve the stability and reliability of the gravity penetration anchor 80 when it is deployed.

[0063] There are two compression springs 30 , which are installed between the bearing portion 21 and the hull 90 . The elastic force of the compression springs 30 on the bearing portion 21 can drive the two L-shaped support portions 23 away from each other.

[0064] Specifically, one end of the two bearing parts 21 that are close to each other is fixedly connected to the top end of the L-shaped connecting part 22, the compression spring 30 is arranged along the transverse direction, and one end of the compression spring 30 is fixedly connected to the hull 90, and the other end of the compression spring 30 is fixedly connected to one end of the two bearing parts 21 that are away from each other; the compression spring 30 has sufficient rigidity to ensure that a large elastic force is released at the moment of release, pushing the release link 20 to rotate around the support shaft 10, so that the top ends of the two release links 20 are driven close to each other through the elastic force of the compression spring 30, thereby realizing the automatic release of the gravity penetration anchor 80.

[0065] There are two ballasts 40, which are symmetrically arranged on both lateral sides of the support shaft 10. The two ballasts 40 are placed one by one above the load-bearing part 21, and the gravity effect of the ballast 40 on the load-bearing part 21 (which is much greater than the elastic force of the compression spring 30) can drive the two L-shaped support parts 23 to approach each other.

[0066] The lifting mechanism 50 includes a hydraulic jack 51, a connecting plate 52 and a guide rod 53. The hydraulic jack 51 is located directly above the support shaft 10, and the bottom end of the hydraulic jack 51 is fixedly connected to the hull 90, and the top end of the hydraulic jack 51 is fixedly connected to the connecting plate 52, and the connecting plate 52 is fixedly connected to two ballasts 40; the guide rod 53 is arranged in the vertical direction, and the top end of the guide rod 53 is fixedly connected to the hull 90, and the bottom end of the guide rod 53 is inserted into the guide hole of the connecting plate 52, for guiding the lifting and lowering of the ballast 40.

[0067] The attitude sensing module 60 is a Bluetooth six-axis sensor, which is fixedly installed inside the gravity penetration anchor 80 and is used to obtain real-time attitude information of the gravity penetration anchor 80. The Bluetooth six-axis sensor can output real-time six-axis attitude data of the anchor body 81 through a Bluetooth signal, and the terminal control module 70 receives the Bluetooth signal to update the recorded data in real time.

[0068] The terminal control module 70 is connected to the posture sensing module 60 via wireless transmission electrical signals, and is used to receive real-time posture information of the anchor body 81 detected by the posture sensing module 60. The terminal control module 70 is connected to the lifting mechanism 50 via a signal line, and the terminal control module 70 can control the lifting mechanism 50 to drive the ballast 40 to rise and fall according to the real-time posture information.

[0069] Preferably, the terminal control module 70 has a built-in virtual electronic lock unit, which can ensure that the hydraulic jack 51 cannot obtain a lifting signal before the installation ship arrives at the anchoring point. When the GPS system transmits the arrival release position signal to the terminal control module 70, the terminal control module 70 will unlock the electronic virtual safety lock.

[0070] Three signal indicator lights are provided on the terminal control module 70 , wherein the first signal indicator light indicates the transport state, the second signal indicator light indicates the positioning state, and the third signal indicator light indicates the unlocked state to be released.

[0071] Embodiment, a method for automatically placing a gravity penetration anchor, the method using the above-mentioned automatic release device for the gravity penetration anchor, the method comprising the following steps:

[0072] Preparation work: transport the anchor body 81 to the designated installation sea area via the installation vessel.

[0073] Step 1: The snap plate 82 is fixedly connected to the anchor body 81 via the recovery cable 83 .

[0074] Specifically, one end of the recovery cable 83 is fixedly connected to the buckle plate 82 , and the other end of the recovery cable 83 is fixedly connected to the mooring point at the tail of the anchor body 81 .

[0075] Step 2: Move the snap plate 82 between the two L-shaped support parts 23 , and apply gravity to the release link 20 through the ballast 40 , so that the two L-shaped support parts 23 are closed and support and fix the snap plate 82 .

[0076] Specifically, the anchor body 81 is first lifted by a lifting device, and then the snap plate 82 is moved between the two L-shaped support parts 23. Finally, the ballast 40 is loaded on the release link 20 through the jacking mechanism 50, so that the two L-shaped support parts 23 are close to each other to vertically support and fix the snap plate 82, so that the anchor body 81 is in a suspended state.

[0077] The buckle plate 82 is a disc-shaped structure and can be fixed by two L-shaped support parts 23 in a closed state to prevent it from slipping.

[0078] Step 3: The terminal control module 70 identifies whether the anchor point has been reached based on the position signal transmitted by the GPS. If so (the error range of the position data transmitted by the GPS is less than the preset value), the virtual electronic lock insurance is released to allow the lifting signal to be transmitted to the hydraulic jack 51; if not, the position of the anchor body 81 is moved and identification continues.

[0079] Step 4: the terminal control module 70 receives the real-time posture information of the anchor body 81 detected by the posture sensing module 60 .

[0080] Specifically, the initialization signal of the Bluetooth six-axis sensor is calibrated based on the vertical direction, and the Bluetooth six-axis sensor transmits the real-time posture data of the anchor body 81 to the terminal control module 70 .

[0081] Step 5: The terminal control module 70 determines whether the real-time posture information meets the delivery requirements (determine whether the vertical position error of the anchor body 81 is within the preset error range). If so, the terminal control module 70 sends a lifting signal to the lifting mechanism 50, and the lifting mechanism 50 lifts the ballast 40 upward. Under the elastic force of the compression spring 30, the lateral spacing between the two L-shaped support parts 23 increases and releases the snap plate 82, so that the gravity penetration anchor 80 falls freely under the action of gravity, completing the release process.

[0082] Compared with the prior art, this application has at least the following beneficial technical effects:

[0083] The automated gravity penetration anchor releasing device of the present application is suitable for unmanned automatic installation of gravity penetration anchors under complex sea conditions.
