The following Figures 1-6 The preferred embodiments of the utility model are described in further detail:

[0033] As Figures 1-6The utility model discloses an anchor chain guide groove for buoy operation, which comprises:

[0034] The support 3 is arranged in pairs, and the bottoms of the support 3 arranged in pairs are fixed on the deck of the ship body correspondingly and are arranged at a certain distance apart from each other;

[0035] The roller 1 is rotatably installed between the two supports 3 through the pin shaft assembly 2, and the middle part of the wheel body of the roller 1 is provided with a groove for supporting and accommodating the anchor chain;

[0036] The supporting groove 4 is arranged at the front end of the roller 1 correspondingly and is fixedly connected to the support 3 and the outer plate of the ship body, and is used for supporting the anchor chain and guiding the anchor chain to the front lower side of the deck of the ship body;

[0037] In an embodiment, the support 3 is made of a rectangular steel plate, a step is cut out at the top of the front end of the support 3 for installing the supporting groove 4, and the top of the rear end of the support 3 serves as the installation part of the roller 1; in consideration of avoiding the problem of bumping and injuring the installer, the position of the top of the rear end of the support 3 is preferably in the form of a circular arc chamfer;

[0038] In an embodiment, the supporting groove 4 is also made of a steel plate, and the supporting groove 4 comprises a bottom supporting plate 401 and a side baffle 402; the bottom supporting plate 401 comprises a horizontal section at the rear end and an arc-shaped section at the front end, the horizontal section of the bottom supporting plate 401 is arranged on the front end of the two supports 3 and is fixedly connected to the two supports 3, the arc-shaped section of the bottom supporting plate 401 gradually lowers from the rear end to the front end, and the side baffle 402 is vertically arranged at the position of the two side edges of the bottom supporting plate 401, the top end of the side baffle 402 is arranged beyond the upper edge of the bottom supporting plate 401 to limit the lateral displacement of the anchor chain, the bottom end of the front section plate body of the side baffle 402 is arranged beyond the lower edge of the bottom supporting plate 401 and is fixedly connected to the outer plate of the ship body, and the arrangement of the arc-shaped section can make the anchor chain naturally descend and flow at the front end, thereby avoiding the problem of stagnation of the anchor chain at the front section of the bottom supporting plate 401;

[0039] In consideration of the fact that the anchor chain will have greater displacement at the front end, in order to avoid affecting the smoothness of the guide-out or recovery of the anchor chain due to the large-angle corner of the front edge of the side baffle 402 in the movement process of the anchor chain, in an embodiment, the front end of the supporting groove 4 is in the form of a bell mouth, that is, the width of the front edge of the bottom supporting plate 401 gradually increases, and the side baffle 402 is correspondingly provided with a corner;

[0040] Similarly, in order to avoid the problem of bending and stacking of the anchor chain between the roller 1 and the bottom supporting plate 401 due to the excessive difference in height, the height of the horizontal section of the bottom supporting plate 401 is not less than the height of the central axis of the roller 1;

[0041] In consideration of safety, in an embodiment, the front end edge and the rear end top of the side baffle 402 are both in the form of an arc-shaped chamfer structure;
