[0035] like Figure 3 As shown, the anchor shackle fixing hook 3 includes: a pad 3.3, a hook 3.1 and a hook ring 3.2, wherein the pad 3.3 is welded and fixed to the side of the curb of the river boat 1 driving road, and a hook ring 3.2 is arranged on the pad 3.3, one end of the hook 3.1 is connected to the hook ring 3.2, and the other end is used to hook the anchor shackle 2.1 to prevent the anchor rod 2.2 from moving.

[0036] like Figure 4 As shown, the anchor crossbar fixer 4 includes: a hanger 4.1, a pressure anchor block 4.2, a nut 4.3, a screw rod 4.4, a handle 4.5 and a chain ring 4.6; the two hangers 4.1 are arranged opposite to each other and are respectively welded and fixed on the two inner walls of the anchor pit 1.2 of the river boat 1; the pressure anchor block 4.2 adopts a pressure anchor flat steel, and the two pressure anchor blocks 4.2 are arranged opposite to each other, and the upper ends thereof clamp the nut 4.3 and are respectively welded and fixed with the nut 4.3 to form a groove structure; the lower ends respectively contact with the two hangers 4.1 through the protrusions extending outwards, and the pressure anchor blocks 4.2 are limited by the hangers 4.1. Thus, the anchor block 4.2, the nut 4.3 and the anchor head pit 1.2 are engaged with each other to form a mouth-shaped structure. After the anchor cross bar 2.4 extends into the mouth-shaped structure, the screw rod 4.4 is then inserted into the nut 4.3, and the screw rod 4.4 is tightened by turning the handle 4.5 on the screw rod 4.4 to achieve compression of the anchor cross bar 2.4 and prevent the anchor cross bar 2.4 from moving.

[0037] In order to prevent the assembly formed by the two pressure anchor blocks 4.2 and the nut 4.3 from being lost during use, the outer side of one of the pressure anchor blocks 4.2 is connected to the side wall of the anchor head pit 1.2 through a chain ring 4.6.

[0038] like Figure 5 As shown, when the river boat 1 is in operation, two Danforth anchors 2 are placed on both sides of the roadway of the river boat 1, the anchor claw groove 1.1 is located on the side of the roadway curb, the anchor head pit 1.2 is located on the deck surface, and the two parts of the anchor fixing device 1.3 are welded and fixed to the side of the roadway curb and the side wall of the anchor head pit 1.2, forming a whole with the river boat 1; the anchor head 2.5 of the Danforth anchor 2 falls into the anchor head pit 1.2 located on the deck surface of the river boat 1, and the anchor claw 2.3 extends into the anchor claw groove 1.1 located on the roadway curb of the river boat 1, which is used for auxiliary fixation of the Danforth anchor 2; the anchor rod 2.2 is connected and fixed to the river boat 1 through the anchor shackle fixing hook 3 located on the side of the roadway curb, and the anchor cross bar 2.4 is connected and fixed to the river boat 1 through the anchor cross bar fixer 4 located on the side wall of the anchor head pit 1.2, thereby fixing the Danforth anchor 2 on the river boat 1. Figure 6 As shown, when the river boat 1 is folded for transportation or storage, the Danforth anchor 2 and the anchor fixing device 1.3 are located in the gap formed by the road edge and the deck surface of the river boat 1, and do not interfere with the structure of the river boat 1.

[0039] When the Danforth anchor 2 needs to be removed for use, the connection between the shackle 3.2 and the anchor shackle 2.1 is directly disconnected, and the screw 4.4 is loosened by turning the handle 4.5 on the screw 4.4 to release the pressure on the anchor crossbar 2.4.

[0040] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
