DETAILED DESCRIPTION

[0023] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1 and Figure 2 The figure shows an anchoring device for a floating dock, comprising an anchor pile 1, a rotating shaft 2, and a tightening disc 3. The anchor pile 1 is installed at the water's edge. The rotating shaft 2 is rotatably mounted on the anchor pile 1, with the axis of the rotating shaft 2 being arranged horizontally and parallel to the water's edge. The tightening disc 3 has at least two members and is spaced apart on the rotating shaft 2 along the axis thereof. The tightening disc 3 is used to retract and release the anchor chain connected to the floating dock.

[0025] Staff connect the anchor chains at multiple connection points on the floating dock's shoreline to multiple take-up discs 3 on the shoreside shaft 2, with the anchor chains parallel to each other. By controlling the rotation of the shaft 2 connected to the anchor pile 1, the shaft 2 drives the take-up discs 3, which are arranged along the axis of the shaft 2, to rotate. Multiple take-up discs 3 simultaneously retract and release the anchor chains connected to the floating dock. After retraction and release, the rotation of the shaft 2 is limited by a locking mechanism to prevent rotation. This solution uniformly applies force to the floating dock through unified retraction and release, improving stability and balance during the retraction and release process. It also allows for the simultaneous retraction and release of multiple anchor chains, which also improves retraction and release efficiency. The number of take-up discs 3 can be increased as needed. The embodiment shown in the figure is a schematic diagram of a system with two take-up discs 3. The anchor pile 1 is provided with a rotary drive device, through which the rotating shaft 2 can be rotated. There are many types of rotary drive components. Generally, the purpose of driving the rotating shaft 2 to rotate can be achieved by a hand wheel or a servo motor, and the purpose of locking the rotating state of the rotating shaft 2 can be achieved by designing a locking mechanism. The rotary drive component of the scheme in the figure is a servo motor, which has an automatic locking function.

[0026] like Figure 1 、 Figure 2 and Figure 8 As shown: the tightening disk 3 is adjustably arranged along the axial direction of the rotating shaft 2, a through hole is provided in the center of the tightening disk 3, and the rotating shaft 2 is loosely matched with the through hole. The anchoring device also includes a fastening component 4 for locking the position of the tightening disk 3 on the rotating shaft 2.

[0027] The fit between the through-hole and the rotating shaft 2 allows the tightening disc 3 to be adjusted along the axis of the rotating shaft 2. After adjusting the tightening disc 3 to the desired position, the tightening disc 3 is secured to the rotating shaft 2 using the fastening assembly 4, ensuring synchronization of the movement of the tightening disc 3 and the rotating shaft 2. The fastening device between the tightening disc 3 and the rotating shaft 2 prevents relative slippage between the tightening disc 3 and the rotating shaft 2.

[0028] like Figure 7 As shown: the cross section of the rotating shaft 2 and the cross section of the through hole are polygonal.

[0029] The shape of the hole at the center of the tightening disk 3 matches the cross-sectional shape of the rotating shaft 2. During rotation, the polygonal rotating shaft 2 and the tightening disk 3 mounted on it will not rotate relative to each other. Furthermore, when the rotating shaft 2 stops rotating, the tightening disk 3 also stops rotating, preventing backlash. The cross-section shown in the figure is hexagonal, resulting in a hexagonal prism-shaped rotating shaft 2.

[0030] like Figure 1 、 Figure 6 and Figure 7 As shown: the fastening assembly 4 includes a first pin hole 41, a second pin hole 42 and a fastening pin 43; the first pin hole 41 radially penetrates both sides of the tightening disk 3 and passes through the through hole; the second pin hole 42 radially penetrates the rotating shaft 2; when the fastening assembly 4 is in working state, the first pin hole 41 and the second pin hole 42 are located on the same axis, and the fastening pin 43 is inserted into the first pin hole 41 and the second pin hole 42.

[0031] The tightening disk 3 is provided with a first pin hole 41 at both ends, and both are set through the hole. At least six second pin holes 42 are equidistantly provided on the rotating shaft 2. The spacing between the two first pin holes 41 set at the head and tail of the tightening disk 3 is the same as the spacing between two adjacent pin holes on the rotating shaft 2. During operation, when the tightening disk 3 moves to the specified position and needs to be fixed by the fastening component 4, the first pin hole 41 and the second pin hole 42 are first aligned, and then the fastening pin 43 is passed between the first pin hole 41 and the second pin hole 42, so as to achieve the fastening effect of the tightening disk 3 and the rotating shaft 2.

[0032] like Figure 5 and Figure 6 As shown, the tightening disk 3 includes a first semi-circular disk 31 and a second semi-circular disk 32, which are detachably and securely connected. The first semi-circular disk 31 and the second semi-circular disk 32 are provided with a first groove and a second groove on their joint surfaces for forming a through hole.

[0033] The tightening disk 3 is composed of a first semi-circular disk 31 and a second semi-circular disk 32. The splicing surfaces of the first semi-circular disk 31 and the second semi-circular disk 32 are respectively provided with a first groove and a second groove that can be spliced ​​into a through hole. After splicing, the first groove and the second groove are loosely matched with the rotating shaft 2. When in use, the rotating shaft 2 is first clamped into the first groove, and then the second semi-circular disk 32 is clamped with the first semi-circular disk 31 to form a fastened connection. At this time, the tightening disk 3 composed of the first semi-circular disk 31 and the second semi-circular disk 32 has been completely installed on the rotating shaft 2. Since the tightening disk 3 is formed by the first semi-circular disk 31 and the second semi-circular disk 32 being clamped, the installation of the tightening disk 3 no longer needs to be inserted from one end of the rotating shaft 2, which makes the installation of the tightening disk 3 more convenient.

[0034] like Figure 5 、 Figure 6 and Figure 8 As shown, a clamping block 312 extends from one end of the first semi-circular disk 31 toward the second semi-circular disk 32, and a clamping groove 311 is provided on the second semi-circular disk 32 for accommodating the clamping block 312. A lifting ear 313 extends from the splicing surface of the first semi-circular disk 31 at the anchor chain retracting position toward the second semi-circular disk 32, and a notch 314 is provided on the second semi-circular disk 32 for accommodating the lifting ear 313.

[0035] The first semicircular groove and the second semicircular groove are respectively clamped on both sides of the rotating shaft 2, and the splicing surfaces of the first semicircular disc 31 and the second semicircular disc 32 are oppositely coplanar. The first semicircular disc 31 and the second semicircular disc 32 are staggered. The first semicircular disc 31 moves toward the second semicircular disc 32 along the axial direction of the rotating shaft 2 to form a complete tightening disc 3. At this time, the clamping block 312 is overlapped in the clamping groove 311, so that the first semicircular disc 31 and the second semicircular disc 32 will no longer have relative displacement after being clamped, and a lifting ear 313 is provided on the splicing surface of the first semicircular disc 31 at the anchor chain retracting position, and the second semicircular disc 32 has a notch 314 to accommodate the lifting ear 313. After splicing, the cooperation between the lifting ear 313 and the notch 314 will further stabilize the tightening disc 3 and also provide a place for the anchor chain to be tied.

[0036] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
