Description

Technical Field

[0001] This utility model relates to the field of cargo ship manufacturing, and in particular to a ship anchor chain retraction and deployment structure. Background Technology

[0002] Existing marine anchor chain lockers typically rely on a single flush, which is insufficient to thoroughly remove silt and sand from the anchor chains. Furthermore, the internal partitions of these lockers are often horizontal and lack guidance, allowing the flushed silt to flow without a directional path, leading to its accumulation and requiring frequent manual cleaning, increasing maintenance costs and failing to meet the demands for efficient anchor chain locker operation. For example, Chinese utility model patent CN208085940U discloses a "ship anchor chain locker and a ship containing it," which uses a single water jet to completely blow silt and sand into the locker. However, the partition structure is not optimized, and the drainage holes are easily blocked by the anchor chains, leading to siltation and low cleaning efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a marine anchor chain deployment and retrieval structure that is easy to clean and handle mud and sand.

[0004] The purpose of this utility model is achieved as follows: a marine anchor chain deployment and retrieval structure includes an anchor chain compartment, an anchor chain channel, and an anchor chain; the anchor chain compartment is a cylindrical structure with one end open, one end of the anchor chain is connected inside the anchor chain compartment, and the main structure is placed inside the anchor chain channel and connected to the ship's anchor; a first flushing nozzle group is provided inside the anchor chain channel, and a second flushing nozzle group is provided inside the anchor chain compartment; the bottom of the anchor chain compartment is set as a conical structure, and a mud and sand discharge hole is provided at the center of the bottom of the anchor chain compartment; a partition is provided above the mud and sand discharge hole, the partition is set as a conical structure, and multiple sets of guide grooves are provided along the conical surface of the partition, and multiple sets of through holes are provided in the guide grooves.

[0005] Preferably, the first flushing nozzle group consists of two sets of first flushing nozzles, one set of first flushing nozzles being located in the upstream region of the anchor chain channel and the other set of first flushing nozzles being located in the downstream region of the anchor chain channel; the two sets of first flushing nozzles are staggered in the circumferential direction of the anchor chain channel, respectively located at the top and bottom of the axial direction of the anchor chain channel.

[0006] Preferably, the second flushing nozzle group consists of two sets of second flushing nozzles, which are symmetrically arranged in the diameter direction of the anchor chain compartment.

[0007] Preferably, both the first flushing nozzle assembly and the second flushing nozzle assembly are recessed within their respective inner walls.

[0008] Preferably, the bottom of the bulkhead is connected and fixed to the wall of the anchor chain compartment via a bracket; a support column is provided between the bulkhead and the bottom of the anchor chain compartment; the diameter of the bottom edge of the bulkhead is smaller than the diameter of the anchor chain compartment, and the gap between the outer bottom edge of the bulkhead and the anchor chain compartment is smaller than the minimum size of the anchor chain.

[0009] Preferably, the guide groove extends downward from the top of the partition to the bottom edge of the support partition.

[0010] Compared with the prior art, the advantages of this utility model are:

[0011] 1. Two sets of first flushing nozzles perform the initial flushing, and work in conjunction with the second flushing nozzle set in the anchor chain compartment for secondary cleaning, forming a segmented flushing mode, which greatly improves the mud and sand removal effect and ensures the long-term stable operation of the flushing system.

[0012] 2. The bottom and bulkhead of the anchor chain compartment adopt a conical structure, combined with the design of guide grooves and through holes, so that the washed mud and sand can flow quickly along the guide grooves, fall into the bottom of the compartment through the gaps between the through holes and the edges of the bulkheads, and finally be discharged through the central mud and sand discharge hole, avoiding the phenomenon of mud and sand accumulating easily and being difficult to clean in traditional anchor chain compartments.

[0019] like Figure 1-2 As shown, a marine anchor chain deployment and retrieval structure includes an anchor chain compartment 1, an anchor chain channel 2, and an anchor chain 3. The anchor chain compartment 1 is a cylindrical structure with one end open. One end of the anchor chain 3 is connected inside the anchor chain compartment 1, and the main structure is placed inside the anchor chain channel 2 and connected to the ship's anchor. A first flushing nozzle group 4 is provided inside the anchor chain channel 2, and a second flushing nozzle group 5 is provided inside the anchor chain compartment 1. The bottom of the anchor chain compartment 1 is set as a conical structure, and a mud and sand discharge hole 6 is provided at the center of the bottom of the anchor chain compartment 1. A partition 7 is provided above the mud and sand discharge hole 6. The partition 7 is set as a conical structure, and multiple sets of guide grooves 701 are provided along the conical surface of the partition 7. Multiple sets of through holes 702 are provided in the guide grooves 701. The guide grooves and through holes are used to guide mud and sand out from the partition.

[0020] like Figure 1As shown, the first flushing nozzle group 4 consists of two sets of first flushing nozzles 401. One set of first flushing nozzles 401 is located in the upstream area of ​​the anchor chain channel 2, and the other set of first flushing nozzles 401 is located in the downstream area of ​​the anchor chain channel 2. The two sets of first flushing nozzles 401 are staggered in the circumferential direction of the anchor chain channel 2, respectively located at the top and bottom of the axial direction of the anchor chain channel 2. The two sets of first flushing nozzles perform the initial flushing of the anchor chain body. Most of the mud and sand will be flushed out directly from the anchor chain channel, avoiding most of the mud and sand from falling into the anchor chain compartment. At the same time, the installation position of the two sets of first flushing nozzles is optimized to prevent the upstream first flushing nozzle from blowing mud and sand to the downstream first flushing nozzle during flushing, further avoiding damage or blockage to the downstream first flushing nozzle.

[0021] like Figure 1 As shown, the second flushing nozzle group 5 consists of two sets of second flushing nozzles 501. The two sets of second flushing nozzles 501 are symmetrically arranged in the diameter direction of the anchor chain compartment 1. The two sets of second flushing nozzles can perform secondary flushing on the anchor chain body to further avoid mud and sand residue on the anchor chain body.

[0022] like Figure 1 As shown, the first flushing nozzle group 4 and the second flushing nozzle group 5 are both recessed in their respective inner walls, ensuring that the built-in flushing nozzles are not touched by the anchor chain, thus further protecting the main body of the flushing nozzles and preventing damage to them.

[0023] like Figure 1-2 As shown, the bottom of the bulkhead 7 is connected and fixed to the wall of the anchor chain compartment 1 by a bracket; a support column 8 is provided between the bottom of the bulkhead 7 and the anchor chain compartment 1; the diameter of the bottom edge of the bulkhead 7 is smaller than the diameter of the anchor chain compartment 1, and the gap between the bottom outer edge of the bulkhead 7 and the wall of the anchor chain compartment 1 is smaller than the minimum size of the anchor chain 3. When the anchor chain is on the bulkhead, the anchor chain will not block the gap between the bulkhead and the wall of the anchor chain compartment.

[0024] like Figure 1-2 As shown, the guide groove 701 extends downward from the top of the partition plate 7 to the bottom edge of the support partition plate 7. When the anchor chain is placed on the partition plate, the guide groove will not be blocked by the anchor chain body, and the mud and sand can be quickly discharged from the grid plate.

[0025] The working principle of this utility model is explained as follows: During anchor retrieval, the anchor chain carrying mud and sand is returned to the anchor chain compartment through the anchor chain channel. First, two sets of first flushing nozzles in the anchor chain channel perform an initial flush on the anchor chain, with most of the mud and sand being discharged directly from the anchor chain channel. Subsequently, the anchor chain enters the anchor chain compartment, where two sets of symmetrical second flushing nozzles further flush it, removing any remaining mud and sand. The flushed mud and sand fall onto a conical partition with guide grooves and through holes. The mud and sand follow the guide grooves, through the through holes, and fall into the conical area at the bottom of the compartment from the gap between the outer edge of the bottom of the partition and the wall of the anchor chain compartment, finally being discharged through the central mud and sand discharge hole, achieving efficient mud and sand removal.
