[0054] Figure 1 Figure 15 is a schematic structural view of the sacrificial anode fixing device 2 installed on the anchor shackle 1. As Figure 1 shown, the sacrificial anode fixing device 2 is used to fixedly install the sacrificial anode 3 on the anchor shackle 1, facilitating the installation and removal of the sacrificial anode 3. The anchor shackle 1 referred to in this application refers to any member that forms an anchor chain, including the anchor shackles 1 connected end to end, and also includes members provided at the end or other parts of the anchor chain. A cavity is provided in the middle of the anchor shackle 1, and an underwater robot can insert the sacrificial anode fixing device 2 installed with the sacrificial anode 3 into the cavity of the anchor shackle 1, and the sacrificial anode 3 contacts the anchor shackle 1 to play an anti-corrosion role.

[0055] Figure 2 Figure 21 is a schematic structural view of the sacrificial anode fixing device 2 installed on the underwater anchor shackle 1. As Figure 2As shown in the figure, the sacrificial anode fixing device 2 installed on the underwater anchor buckle 1 includes a frame 10, a pair of clamping mechanisms 20, and a pair of anti-disengagement mechanisms 30. The frame 10 can install the sacrificial anode 3. A pair of clamping mechanisms 20 are arranged on both sides of the sacrificial anode 3 for clamping the anchor buckle 1. A pair of anti-disengagement mechanisms 30 are used to prevent the sacrificial anode fixing device 2 from moving reversely during the insertion process and from disengaging from the anchor buckle 1 before the clamping mechanism 20 clamps it.

[0056] Specifically, the frame 10 includes a mounting member 13, a cross beam 11, and a baffle 12. The mounting member 13 is used to install the sacrificial anode 3, and the cross beam 11 and the baffle 12 are used to assist in fixing the sacrificial anode 3. Figure 3 is a schematic structural view of the cross beam 11 and the baffle 12 of the frame 10. As shown in Figure 2 and Figure 3 shown, the cross beam 11 can be a channel steel, and its length is greater than the width of the cavity of the anchor buckle 1. The cross beam 11 is provided with a third handle 111 that is convenient for the underwater robot to grasp. A pair of baffles 12 are oppositely arranged at the middle position of the cross beam 11. The sacrificial anode 3 is installed in the space between the pair of baffles 12. The baffles 12 can guide the sacrificial anode 3 during the installation process and protect the sacrificial anode 3 after installation. In this embodiment, a pair of clamping mechanisms 20 are respectively arranged at both ends of the cross beam 11, and a pair of anti-disengagement mechanisms 30 are respectively arranged on both sides of the end position of the cross beam 11, which can play a role in balancing the force.

[0057] Figure 4 is a schematic structural view of the mounting member 13 of the frame 10, Figure 5 is a sectional structural view of the mounting member 13. As shown in Figure 2 、 4 and Figure 5, the mounting member 13 includes a mounting seat 131, a locking rod 133, a fixing pin 137, a second spring 138, and a stopper 135. After the underwater robot unlocks by rotating the second handle 132, the second spring 138 drives the locking rod 133 and the stopper 135 to move towards the mounting seat 131, so that the sacrificial anode 3 can be clamped between the stopper 135 and the mounting seat 131, completing the installation of the sacrificial anode 3.

[0058] Figure 6 is a schematic structural view of the mounting seat 131. As shown in Figure 5 and Figure 6 shown, the mounting seat 131 includes a through receiving cavity 211. The side wall of the receiving cavity 211 is provided with a first groove 1311 extending in the circumferential direction and a second groove 1312 extending in the vertical direction and communicating with the first groove 1311.

[0059] The locking rod 133 is integrally in a "T" - shaped structure, with a second handle 132 provided at the top and passing through the receiving cavity 211 of the mounting base 131 at the bottom. The locking rod 133 further includes a hook portion 134 extending in the radial direction, and the hook portion 134 is used to be embedded in the connection groove 302 of the sacrificial anode 3. The fixing pin 137 passes through the locking rod 133 in the radial direction, and at least one end is located in the first groove 1311, and the second spring 138 is provided between the fixing pin 137 and the mounting base 131. The stopper 135 is connected to the locking rod 133 and protrudes from the locking rod 133 in the radial direction for carrying the sacrificial anode 3. In this embodiment, the side of the stopper 135 for carrying the sacrificial anode 3 has an outward - inclined area 136, and the inclined area 136 is used to push the sacrificial anode 3 outwards when carrying the sacrificial anode 3.

[0060] In the initial state, both ends of the fixing pin 137 are embedded in the first groove 1311, and the second spring 138 is in a compressed state. At this time, the connection groove 302 of the sacrificial anode 3 can be aligned with the hook portion 134, and the sacrificial anode 3 is placed between the stopper 135 and the mounting base 131. After being inserted into the anchor buckle 1, by rotating the locking rod 133 through the second handle 132, the locking rod 133 drives the fixing pin 137 to rotate in the first groove 1311 until the fixing pin 137 moves to the position connecting the second groove 1312, and then the second spring 138 drives the locking rod 133 and the stopper 135 to move towards the mounting base 131. At this time, the fixing pin 137 moves along the second groove 1312. During the movement, the inclined area 136 of the stopper 135 drives the sacrificial anode 3 to move towards the mounting base 131 and at the same time pushes the sacrificial anode 3 to move to both sides. In this way, when the sacrificial anode 3 is inserted into the anchor buckle 1, the saw - teeth 301 on both sides of the sacrificial anode 3 can cut open the surface layer of the anchor buckle 1 and make electrical contact with the anchor buckle 1, and be pressed against both sides of the inner wall of the anchor buckle 1, playing an anti - corrosion role.

[0061] When the sacrificial anode 3 needs to be removed, press the second handle 132, and the locking rod 133 and the stopper 135 move in the direction away from the mounting base 131, and the distance between the mounting base 131 and the stopper 135 increases, so that the sacrificial anode 3 can be conveniently removed.

[0062] Figure 7 It is a schematic structural diagram of the clamping mechanism 20. Figure 8 It is a schematic cross - sectional structural diagram of the clamping mechanism 20. As Figure 7 and 8As shown in the figure, the clamping mechanism 20 includes a first handle 25, a base 21, a ratchet wheel 27, a nut 26, a connecting pipe 22, a moving rod 23 and a hook foot 24. The sacrificial anode fixing device 2 includes at least a pair of the clamping mechanisms 20, and the clamping mechanisms 20 are symmetrically arranged relative to the mounting member 13. In this embodiment, the number of the clamping mechanisms 20 is a pair, which are respectively arranged on both sides of the mounting member 13 and located at both ends of the cross beam 11.

[0063] The base 21 is connected to the end position of the cross beam 11 of the frame 10 and has a through cavity 211 inside. The nut 26 is clamped in the cavity 211 along the rotation direction. The nut 26 is rotatably connected to the base 21, and the first handle 25 is connected to the nut 26 for driving the nut 26 to rotate. The connecting pipe 22 is hollow inside and one end is connected to the base 21. The moving rod 23 passes through the cavity 211 and is located inside the connecting pipe 22. The upper thread 231 is threadedly connected to the nut 26 located in the cavity 211. A hook foot 24 is provided at the bottom of the moving rod 23, and the moving rod 23 is movably connected to the base 21. When the sacrificial anode fixing device 2 is inserted into the underwater anchor buckle 1, the moving rod 23 moves close to the frame 10, and the anchor buckle 1 is clamped by the hook foot 24 and the frame 10. In this way, during the process of rotating the nut 26, the moving rod 23 can be driven to move axially relative to the base 21, realizing the function of clamping the anchor buckle 1.

[0064] Figure 10 It is a structural schematic diagram of the locking rod 133, the ratchet wheel 27 and the first spring 28. As Figure 9 and Figure 10 shown, the nut 26 is rotatably arranged in the cavity 211 of the base 21 through a thrust ball bearing 29 and is threadedly connected to the moving rod 23. The upper part of the nut 26 is clamped with the first handle 25 along the rotation direction, that is, the first handle 25 can move axially relative to the nut 26, but is locked relative to the nut 26 along the rotation direction. In order to realize the unlocking and locking functions of the nut 26, the inner wall of the cavity 211 is provided with a first tooth (not shown in the figure). The lower part of the nut 26 is sleeved with the ratchet wheel 27. The inner side of the ratchet wheel 27 is axially movably sleeved on the nut 26 and is clamped with the nut 26 along the rotation direction. The outer wall of the ratchet wheel 27 is provided with a second tooth 271 corresponding to the first tooth. During the vertical movement of the ratchet wheel 27, if the first tooth is clamped with the second tooth 271, the ratchet wheel 27 is locked and cannot rotate; when the ratchet wheel 27 moves to a position where it is disengaged from the first tooth and the second tooth 271, the ratchet wheel 27 is unlocked and can rotate relative to the base 21. The first spring 28 abuts between the ratchet wheel 27 and the nut 26 for resetting the ratchet wheel 27.

[0065] In a normal locking state, the first latching tooth of the ratchet 27 engages with the second latching tooth 271 of the base 21. Due to the engagement between the nut 26 and the ratchet 27 in the rotational direction, the rotation locking of the nut 26 can be achieved. When the moving rod 23 needs to be driven, the underwater robot presses the first handle 25, and the first handle 25 drives the ratchet 27 to move in the axial direction of the nut 26 to compress the first spring 28. When the first latching tooth and the second latching tooth 271 are disengaged, the underwater robot can drive the nut 26 to rotate through the second handle 132, and drive the moving rod 23 to move in the axial direction. After the underwater robot releases the first handle 25, the first spring 28 drives the ratchet 27 to move in the axial direction of the nut 26, resets to the position where the first latching tooth engages with the second latching tooth 271, locks the nut 26, and prevents the nut 26 from rotating accidentally.

[0066] Figure 11 Schematic diagram of the structure of the locking rod 133. Figure 8 and Figure 11 As shown, in order to facilitate the control of the rotation angle of the moving rod 23, in this embodiment, the stop pin 221 is inserted into the connecting tube 22 in the radial direction, and the rotating surface of the moving rod 23 is provided with a guide groove 232, and the stop pin 221 passes through the connecting tube 22 and is embedded in the guide groove 232. The guide groove 232 includes a spiral segment 2321 extending in a spiral shape and an axial segment 2322 extending in the axial direction. When the stop pin 221 is located in the spiral segment 2321, the moving rod 23 moves and rotates relative to the base 21 at the same time; when the stop pin 221 is located in the axial segment 2322, the moving rod 23 moves relative to the base 21.

[0067] In this way, during the movement of the moving rod 23 in the axial direction, in the initial state, the rotation angle of the moving rod 23 is located at a position where the hook foot 24 deviates from the anchor buckle 1, so that the hook foot 24 can be prevented from obstructing the insertion of the sacrificial anode 3 into the anchor buckle 1. However, the underwater robot drives the moving rod 23 to move in the axial direction by rotating the nut 26 through the first handle 25. Since the limit pin 221 is embedded in the axial section 2322, the moving rod 23 only moves in the axial direction, which prevents the hook foot 24 from deflecting to a position that obstructs the insertion of the sacrificial anode 3 into the anchor buckle 1. After the sacrificial anode 3 is inserted into the anchor buckle 1, the limit pin 221 follows the moving rod 23 to move to the spiral section 2321. During the movement of the moving rod 23 in the axial direction, the moving rod 23 is guided by the limit pin 221 and rotates, so that the hook foot 24 follows the moving rod 23 to rotate to a position facing the sacrificial anode 3 (i.e. Figure 2 The anchor buckle 1 can be firmly held.

[0068] Figure 12 30 is a schematic diagram of the structure of the anti-slip mechanism 30. Figure 12As shown, the anti - detachment mechanism 30 includes an anti - detachment rod 31, a latch 32, and a torsion spring (not shown in the figure). The end of the anti - detachment rod 31 is connected to the frame 10. The latch 32 is rotatably connected to the anti - detachment rod 31, and the torsion spring abuts between the latch 32 and the anti - detachment rod 31. During the process of inserting the sacrificial anode fixing device 2 into the anchor buckle 1, the latch 32 abuts against the side wall of the anchor buckle 1 under the action of the torsion spring, playing a role in preventing the sacrificial anode fixing device 2 from retrograding and disengaging from the anchor buckle 1.

[0069] The working process of the sacrificial anode fixing device 2 installed on the underwater anchor buckle 1 will be described in detail below.

[0070] First, press the second handle 132 so that the fixing pin 137 enters the first groove 1311 along the second groove 1312, and then rotate the second handle 132 to snap the fixing pin 137 into the first groove 1311. Then, install the sacrificial anode 3 on the stopper 135 and the locking rod 133.

[0071] Then, the underwater robot grabs the third handle 111 and inserts the sacrificial anode fixing device 2 into the anchor buckle 1. During the insertion process, the latch 32 abuts against the anchor buckle 1 to prevent it from disengaging from the anchor buckle 1.

[0072] Next, the underwater robot presses the second handle 132 to unlock the nut 26, and then rotates the second handle 132 to drive the nut 26 to rotate. The nut 26 drives the moving rod 23 to move axially. When the sacrificial anode 3 is completely inserted into the anchor buckle 1, the guide pin guides the moving rod 23 to rotate in the spiral section 2321. After the hook foot 24 hooks the anchor buckle 1, the anchor buckle 1 is tightly held.

[0073] Finally, rotate the second handle 132 to rotate the fixing pin 137 into the first groove 1311. Under the action of the second spring 138, the locking rod 133 clamps the sacrificial anode 3 through the stopper 135. The sacrificial anode 3 moves axially under the action of the stopper 135, and the serrations 301 on both sides cut open the surface of the anchor buckle 1 and make electrical contact with the anchor buckle 1, and are completely pressed against the inner walls on both sides of the anchor buckle 1. The process of removing the sacrificial anode fixing device 2 is the opposite of this, which will not be elaborated here.

[0074] During the installation process of the sacrificial anode fixing device 2 installed on the underwater anchor buckle 1, the underwater robot can insert the sacrificial anode fixing device 2 with the installed sacrificial anode 3 into the anchor buckle 1, and then move the moving rod 23 of the clamping mechanism 20 close to the frame 10 to clamp the anchor buckle 1 through the hook foot 24 and the frame 10, completing the fixing operation of the sacrificial anode fixing device 2. When it is necessary to remove the sacrificial anode fixing device 2, just loosen the hook foot 24 to take away the sacrificial anode fixing device 2, and both the disassembly and assembly operations are very convenient.
