The anchor chain cabin 1 is positioned at the stem position, the anchor machine 3 is horizontally arranged on the deck 10, the deflection angle towards the side of the ship is the same as the central line of the straw mushroom-shaped anchor receiving device 6 in a top view (namely, the central line of the anchor machine 3 and the central line of the straw mushroom-shaped anchor receiving device 6 are on the same plane and are 25-30 degrees as shown in figure 12.

The chain guide 2 is positioned between the anchor machine 3 and the chain cabin 1 and welded on the deck 10. The central surface of the knife chain stopper 5 is coplanar with the anchor 3 and welded to the deck 10. The straw mushroom-shaped anchor receiving device 6 penetrates through the ship body 7 at a pitch angle alpha of 20-25 degrees and a side view angle beta of 30-38 degrees, as shown in fig. 13 and 14, and an upper port-shaped fungus-like portion of the straw mushroom-shaped anchor receiving device 6 is welded on the deck 10. The edge of the fungi cover-like part of the straw mushroom-like anchor receiving device 6 is welded on the outer plate of the ship body 7.

As shown in fig. 2 and 3, the straw mushroom-like anchor receiving device 6 is similar to straw mushrooms in appearance, is formed by casting and forging integrally, has the dual characteristics of pressure casting and forging, and has the characteristics of high strength, high compactness, wear resistance, low production cost, few production procedures and the like. The shape of the straw mushroom-like anchor receiving device 6 is edible straw mushroom. The straw mushroom-shaped anchor receiving device 6 mainly comprises three parts, namely an upper wear-resistant lining 61, a middle anchor rod bin 62 and a lower anchor attaching boss 63. The wear-resistant lining 61 on the upper part of the straw mushroom-shaped anchor receiving device 6 is shaped like a fungus support and is a semi-annular bulge, and is used for stabilizing the anchor chain 4 and preventing the anchor chain 4 from being scratched in the anchor lifting or anchoring process. The anchor rod bin 62 in the middle of the straw mushroom-shaped anchor collecting device 6 is similar to a straw mushroom fungus handle in shape and is a hollow cylinder for collecting the anchor rods 9. The anchor attaching boss 63 at the lower part of the straw mushroom-like anchor receiving device 6 is shaped like a straw mushroom cap and presents an umbrella-like structure for attaching the large-holding-power anchor 8.

The bottom of the straw mushroom-shaped anchor receiving device 6 is provided with an anchor attaching boss 63, the shape of the anchor attaching boss is similar to a straw mushroom fungus cover, the anchor attaching boss 63 is used for attaching the large-holding-power anchor 8 in a tensioning state, the planes A-A and B-B intersect with the anchor attaching boss 63 to form a section (a fourth section JA, a fifth section JB, a sixth section JC and a seventh section JD), and the shape of the anchor attaching boss 63 can effectively increase the attaching area of the large-holding-power anchor 8 and prevent the large-holding-power anchor 8 from being clamped below the anchor attaching boss 63.

As shown in fig. 10, the chain cabin 1 is a receiving area of the chain 4, the middle in the chain cabin 1 protrudes upwards to form a round table 11, a guide arm 12 capable of freely rotating is arranged on the round table 11, the chain 4 pulls the chain 4 to the periphery through a guide channel on the guide arm 12, after the chain 4 contacts the side surface of the round table 11, the chain 4 slides down to the periphery of the round table 11 under the gravity, the chain 4 is uniformly distributed around the chain cabin 1, layered accumulation is realized layer by layer, the phenomenon of winding and knotting is avoided, and the chain 4 is smoothly lifted in the anchoring process through the system of the utility model. As shown in fig. 11, the chain guide 2 has a morning glory-like through-hole structure, i.e., a through-hole structure having a small middle caliber and large openings at both ends.

In this embodiment, one end of the chain guide 2 is rotatably disposed directly above the center position of the round table 11 (the rotation axis of the chain guide 2 is coaxial with the center axis of the round table 11), and the through hole (i.e., the guide channel) in the middle of the other end of the guide arm 12 is vertically disposed directly above the center position of the round table 11 on the inclined side wall around the round table 11.

The working principle of the utility model is as follows:

the anchor chain 4 is connected with a large-grabbing anchor 8, penetrates through the straw mushroom-shaped anchor collecting device 6, is guided to the anchor machine 3 through the guillotine chain stopper 5, the anchor machine 3 provides a pulling force of 11-18 degrees for the anchor chain 4, and the retracted anchor chain 4 is guided into the anchor chain cabin 1 around the anchor machine 3 through the chain guide 2. In the process, the chain guide device 2 guides the anchor chain 4 to enter the anchor chain cabin 1, the simulated morning glory shape of the chain guide device 2 can enlarge the guide area, and the problem that the anchor chain 4 is easy to accumulate on a deck when entering the anchor chain cabin in the prior art is solved. The anchor chain 4 passes through the straw mushroom-shaped anchor receiving device 6 in the process of entering the anchor chain cabin 1, and the chain links of the anchor chain 4 scratch a part of the area of the deck 10 below the knife chain stopper 5 in the moving process due to the action of the gravity of the anchor chain 4, so that the structure of the ship body 7 can be damaged by long-time friction. The shape of the straw mushroom-shaped anchor receiving device 6 is similar to the shape of straw mushrooms, the shape of the wear-resistant liner 61 at the upper part of the anchor receiving device is similar to straw mushroom fungus holders, the wear-resistant liner 61 is semicircular and annular, the anchor chain 4 contacts and rubs the wear-resistant liner 61 firstly in the traction process, and the friction of the anchor chain 4 on the ship body 7 and the anchor rod bin 62 in the middle of the straw mushroom-shaped anchor receiving device 6 is reduced. The anchor rod bin 62 in the middle of the straw mushroom-like anchor collecting device 6 is similar to a straw mushroom stipe in shape and is used for placing the anchor rods 9 in a tensioning state. The final stage of the anchor receiving work is to fix the large-grabbing anchor 8. Most of the traditional fixing modes adopt anchor cavities in the form of bosses with fixed shapes or hidden in the ship body, and the anchor flukes are easy to face downwards or block and the like. The lower part of the straw mushroom-like anchor receiving device 6 is provided with an anchor attaching boss 63, the shape of the anchor attaching boss is similar to a straw mushroom fungus cover, the curved surface of the protruding part of the anchor attaching boss is excessively natural, the curved surface of the protruding part of the anchor attaching boss approaches to a plane, the anchor attaching boss is beneficial to the attachment of the large-grabbing anchor 8, the upper half part of the anchor attaching boss 63 is relatively flat and is close to the plane, the design enables the large-grabbing anchor 8 to realize multipoint contact or even surface contact with the surface of the anchor attaching boss 63 in a tensioning final state, the stability after anchor receiving is improved, and the small part of the top of the anchor attaching boss 63 protrudes to be used for the attachment of an anchor rod 9, so that the movement and the collection position of the anchor rod 9 are not contacted with the anchor rod bin 62. The difference between the lower half part and the upper half part of the inner opening surface of the anchor sticking boss 63 is small, so that the time required for the large-grabbing anchor 8 to contact the upper half part of the anchor sticking boss 63 is reduced, and the anchor clamping probability is reduced.

The utility model can complete the anchor-taking task under the complex working conditions such as 0-6 degrees of pitching, 0-5 degrees of transverse tilting, 100-300 mm/s of anchor-taking speed and the like. According to the utility model, through an electronic anchor pulling test and a wood pattern test, the anchor pulling task is completed under the working conditions. The design of the anchor lips (i.e. the attaching boss 63) solves the problems of anchor blocking, unstable attaching and the like which are easy to occur in the conventional anchor device system. The utility model has large suitable working condition range and solves the problem of small applicable working condition range of the traditional anchor system arrangement.
