Description

Technical Field

[0001] This utility model relates to the field of ship anchors, and in particular to an anchor frame device. Background Technology

[0002] Anchor frames, used for anchoring and retrieval, are typically located on the exposed bow deck. Their protrusion above the deck negatively impacts the ship's stealth capabilities. To improve stealth performance, anchor frames need optimized design, allowing them to be retracted into the deck when not in use, minimizing their influence on the ship's external profile. Furthermore, anchor frames should possess rapid deployment and retrieval capabilities to ensure efficient anchoring operations even in complex sea conditions and to withstand long-term use in the marine environment. Utility Model Content

[0003] The technical problem to be solved by this utility model is: how to improve the stealth of the anchor frame device. In order to solve the above technical problem, this utility model provides an anchor frame device, which is installed on the internal deck of the ship's anchor winch room, including the anchor frame device, the hatch device and the positioning device.

[0016] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0017] like Figures 1 to 6 As shown, a preferred embodiment of the present invention provides an anchor frame device, which is installed on the internal deck 61 inside the ship's anchor winch 6, and includes an anchor frame device 1, a hatch 2 device, and a positioning device. Anchor bracket 1 is fixedly installed with anchor 11, and anchor bracket 1 is rotatably mounted on the inner deck 61 to switch between a first state and a second state. The hatch 2 device includes a hatch 2 and a drive mechanism. The drive mechanism is used to drive the hatch 2 to move to cover or open the anchoring door hole 62 provided on the side wall of the anchor winch 6. The positioning device includes a first positioning component 4 and a second positioning component 5 fixedly disposed on the inner deck 61. The first positioning component is configured to be fixedly connected to the anchor bracket 1 and to limit the anchor bracket 1 to a first state. The second positioning component 5 is configured to be fixedly connected to the anchor bracket 1 and to limit the anchor bracket 1 to a second state. In the first state, one end of the anchor frame device 1 with the anchor 11 protrudes through the anchor gate 62 so that the anchor 11 is located on the outside of the ship's side; in the second state, both ends of the anchor frame device 1 are housed inside the anchor winch chamber 6.

[0018] Specifically, in this embodiment, the anchor frame device 1 used to support and limit the anchor 11 is installed on the inner deck 61 of the anchor winch 6 inside the ship, rather than on a conventional open deck. In this embodiment, the anchor frame device 1 can rotate relative to the inner deck 61, thereby adjusting the orientation and position of the end of the anchor frame device 1. The side wall of the anchor winch 6 used to house the anchor frame device 1 is provided with an anchoring door 62 corresponding to the anchor frame device 1, and a hatch 2 is installed corresponding to the anchoring door 62. In actual use, the anchor frame device 1 switches between a first state and a second state by rotating relative to the inner deck 61. The first state is the anchoring device, and the second state is the stowed state. In the first state, the side of the anchor frame device 1 with the anchor 11 installed passes through the anchoring gate 62, and the other end of the anchor frame device 1 cooperates with the first positioning component 4 to restrict the position of the anchor frame, so that the position of the anchor frame does not loosen or shift, thereby enabling the anchor 11 to be moved to the outside of the hull, and making the subsequent anchoring work more stable and smooth. When it is time to set sail, the anchor 11 needs to be retracted and positioned on the anchor frame device 1 first, and then the anchor frame device 1 is driven to rotate, so that the anchor frame device 1 switches from the first state to the second state. In the second state, the anchor frame device 1 and the anchor 11 on it are completely stored in the anchor winch 6. At the same time, the other end of the anchor frame device 1 cooperates with the second positioning component 5 to restrict and stabilize the position of the anchor frame device 1, so that the anchor frame device 1 does not protrude from the surface of the hull, thereby reducing the radar wave reflection area and better achieving the stealth of the ship. The position of the anchor frame device 1 in the anchor winch 6 is also more stable, and it will not damage other equipment in the anchor winch 6 due to loosening or shifting.

[0019] In some embodiments, the inner deck 61 is provided with an anchor winch 7, which includes a drum structure 71 and a power structure 72. The power structure 72 is used to drive the drum structure 71 to rotate. The drum structure 71 is wound with an anchor chain 12, one end of which is connected to an anchor 11.

[0020] Specifically, during the actual anchoring process, after releasing the chain catcher on the anchor frame 1, the anchor 11 falls rapidly under the influence of gravity, driving the anchor chain 12 to move until the anchor 11 sinks to the seabed, completing the anchoring operation and thus restricting the ship's position. When retrieving the anchor, the power structure 72 drives the drum structure 71 to rotate, continuously winding the anchor chain 12, thereby pulling the anchor 11 from the seabed back to the anchor frame 1. The anchor 11 is then secured at the anchor frame 1, and finally, the anchor 11 and the anchor frame 1 are completely retracted into the windlass compartment 6. The drum structure 71 and the power structure 72 of the windlass device 7 are both housed on the internal deck 61 of the windlass compartment 6, rather than protruding from the exterior of the ship's hull. This ensures the normal anchoring and retrieving operation of the anchor 11 while also improving the ship's stealth capabilities. Furthermore, the power structure 72 can be a motor structure or an engine structure, depending on the load.

[0021] In some embodiments, the inner deck 61 is fixedly equipped with a rotating base 63 and a rotating motor 64. The rotating base 63 is rotatably connected to the anchor frame device 1, and the rotating motor 64 drives the anchor frame device 1 to rotate around the central axis of the rotating base 63. The transmission structure between the rotating base 63 and the anchor frame device 1 can be a gear-chain drive, or a multi-gear meshing drive, etc. For example, the rotating motor 64 drives the internal gears of the rotating base 63 to rotate through a reduction gearbox or similar structure, thereby driving the gears inside the anchor frame device 1 to rotate, and ultimately driving the anchor frame device 1 to rotate. In another embodiment, the rotation of the anchor frame device 1 can also be achieved through the cooperation of gears, racks, and a propulsion motor. The rotation of the anchor frame device 1 around the central axis of the rotating base 63 allows adjustment of the position of its end, enabling the anchor 11 to be stored in the anchor winch 6 or moved outside the ship. Simultaneously, the position of the other end of the anchor frame device 1 is also changed. By cooperating with positioning components and a second positioning component 5 located at different positions, the position of the anchor frame device 1 can be rotated, preventing loosening or displacement of the anchor frame device 1.

[0022] In some embodiments, the first positioning component 4 includes a first positioning block 41, the first positioning block 41 is provided with a first positioning pin 42, and the anchor bracket device 1 is provided with a first positioning hole 13 corresponding to the first positioning pin 42.

[0023] Furthermore, the inner deck 61 is provided with a first sensor 65, which is located on the side of the first positioning block 41 away from the first positioning pin 42. The first sensor 65 is used to monitor whether the anchor frame device 1 is in the first state.

[0024] In one specific embodiment, when the anchor bracket device 1 is in the first state, the central axis of the anchor bracket device 1 is perpendicular to the central axis of the ship, and the central axis of the first positioning pin 42 is parallel to the central axis of the ship. In the first state, the anchor bracket device 1 and the first positioning pin 42 are in a perpendicular state, and the first positioning pin 42 is inserted into the first positioning hole 13 of the anchor bracket device 1, thereby stably restricting the position of the anchor bracket device 1 and preventing the anchor bracket device 1 from loosening and shifting due to excessive anchoring impact during the anchoring process, ensuring the smooth and stable anchoring process. It is understood that in some embodiments, other locking structures can also be provided between the first positioning pin 42 and the first positioning hole 13, as long as they can restrict the position of the anchor bracket device 1 and enable the anchor bracket device 1 to withstand the anchoring impact. For example, they can be used with screws or other threaded structures or other abutment structures. There are many pin locking and limiting structures, so they will not be described in detail here.

[0025] The first sensor 65 can be a photoelectric sensor or a distance sensor, etc. It can determine whether the anchor frame device 1 is in the first state by detecting whether the anchor frame device 1 is in place. When the anchor frame device 1 is detected to have rotated into place, a signal can be sent to the control box, and the anchor chain 12 can be released to start the subsequent anchoring work.

[0026] In some embodiments, the second positioning component 5 includes a second positioning block 51, the second positioning block 51 is provided with a second positioning pin 52, and the anchor bracket device 1 is provided with a second positioning hole 14 corresponding to the second positioning pin 52.

[0027] Furthermore, the inner deck 61 is equipped with a second sensor 66, which is located on the side of the second positioning block 51 where the second positioning pin 52 is located. The second sensor 66 is used to monitor whether the anchor frame device 1 is in the second state.

[0028] The engagement of the second positioning pin 52 and the second positioning hole 14 stably restricts the anchor frame device 1 to the second state, preventing instability and rotation of the anchor frame device 1 due to external factors such as wind and waves during navigation, which could damage the anchor winch compartment 6 and other equipment within it. After the second positioning pin 52 engages with the second positioning hole 14, the second positioning block 51 further restricts the position of the second positioning pin 52, thus stabilizing the position of the anchor frame device 1. The same applies to the engagement between the first positioning pin 42 and the first positioning block 41.

[0029] In addition, the second sensor 66 has the same function as the first sensor 65, which is also used to monitor whether the anchor frame device 1 is in the second state. When it is determined that the anchor frame device 1 is in the second state, a signal will be sent to the control box, and the control box will start to control the drive structure 3 to drive the hatch 2 to move to close the anchor throwing door 62.

[0030] Furthermore, the central axis of the first positioning hole 13 is perpendicular to the central axis of the second positioning hole 14. This facilitates the processing and production of the first positioning hole 13 and the second positioning hole 14; it also facilitates the engagement of the first positioning pin 42 with the first positioning hole 13 and the second positioning pin 52 with the second positioning hole 14. In fact, compared to the alternative embodiment where the first positioning hole 13 and the second positioning hole 14 overlap and are the same hole, in this alternative embodiment, the positioning holes are more prone to wear during long-term use, leading to more loosening and other instability issues in the anchor device 1 in the first and second states.

[0031] In some embodiments, the drive mechanism includes a drive motor 31 and a transmission rod assembly. The drive motor 31 is disposed on the inner wall of the anchor winch chamber 6. The two ends of the transmission rod assembly are respectively connected to the drive motor 31 and the hatch 2. The drive motor 31 drives the hatch 2 to open and close through the transmission rod assembly.

[0032] Furthermore, the transmission rod assembly includes a transmission chain, a transmission shaft 32, and a crankshaft 33. The transmission chain is connected to the transmission shaft 32 and the drive motor 31 respectively, and the two ends of the crankshaft 33 are connected to the transmission shaft 32 and the hatch 2 respectively.

[0033] Specifically, when anchoring is required, the drive motor 31, in conjunction with the transmission rod assembly, first drives the hatch 2 to rotate, thereby opening the hatch 2. Once the hatch 2 is fully open, a signal is sent to the control box. Upon receiving the signal that the hatch 2 is fully open, the anchor frame device 1 will then be driven by the rotary motor 64 to rotate to the first state. The drive motor 31 drives the gears through a reduction gearbox to rotate the transmission chain, which in turn drives the transmission shaft 32 to rotate. The transmission shaft 32 has two arc-shaped crankshafts 33. The hatch 2 rotates around the axis of the transmission shaft 32 via the crankshafts 33, thus opening and closing the hatch 2.

[0034] In summary, this utility model embodiment provides an anchor frame device 1, which can switch between a first state and a second state, thereby switching and changing the position state of the anchor 11. In the non-anchored state, the anchor 11 can be stored in the anchor winch chamber 6 inside the ship's hull, and other supporting equipment of the anchor 11, such as the anchor winch, is also stored in the anchor winch chamber 6, thereby preventing the anchor 11 and other supporting equipment from protruding from the hull and thus improving the overall stealth performance of the ship.

[0035] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
