Description

Technical Field

[0001] The invention relates to the field of dock anchoring, in particular to a mooring device. Background Art

[0002] With the continuous development of my country's marine economy, there is a need to adopt a large number of mobile floating docks that do not damage the marine ecological environment to carry out flexible and maneuverable berthing of cargo ships and loading and unloading of materials. In recent years, the global climate has warmed, typhoons have occurred frequently, and their levels have gradually increased. The storm environment at sea has become increasingly severe, which to a great extent tests the mooring and positioning capabilities of the near-shore shallow water movable floating docks.

[0003] In order to solve this problem, the skilled person in the art has conducted in-depth research, and the patent publication number is "CN111608133A" and the patent name is "A movable floating dock anchoring device and fastening method", which discloses a floating dock, a gravity anchor block, a lifting column, a large-holding force anchor and an anchor chain. The lifting column controls the lifting and lowering of the gravity anchor block, so that the gravity anchor block is anchored on the seabed and the floating dock is fixed on the sea surface. Then, the ship is fixed by the large-holding force anchor and the anchor chain. This floating dock has a simple structure and can be quickly The deployment of floating docks can be completed quickly, which greatly improves the flexibility and maneuverability of floating docks. However, this method has certain requirements on the depth of seawater. On the other hand, after the anchoring of the floating dock is completed, the gravity anchor block is anchored to the seabed and connected to the floating dock through the lifting column. The floating dock cannot move relative to the seabed. When wind and waves come, the shaking of the ship will produce a rigid impact on the floating dock through the anchor chain. The internal stress of the anchor chain will reach a peak when it is tightened, which will cause the anchor of the gravity anchor block to loosen from the seabed or the anchor chain to break. Therefore, how to design a mooring device that can reduce the peak internal stress of the anchor chain when the anchor chain is subjected to tensile impact to improve the stability of the mooring still needs to be continuously studied. Summary of the invention

[0004] In view of this, an object of the present invention is to overcome the deficiencies of the prior art and provide a mooring device which can reduce the peak internal stress of the anchor chain when the anchor chain is subjected to a tensile impact so as to improve the mooring stability.

[0005] In order to solve the above technical problems, the technical solution of the present invention is:

[0006] A mooring device comprises a floating island, wherein a first hook rod for connecting a vessel or a dock is provided on the floating island, an anchoring assembly is provided on the lower side of the floating island, and the anchoring assembly comprises a cantilever, a beam and a baffle, wherein the cantilever is fixedly connected to the floating island, a plurality of beams are provided in a linear array in a vertical direction and are all fixedly connected to the cantilever, a baffle for closing the interval between two adjacent beams is provided between the beams, the beams are movably connected to the baffles, and the baffles are connected to a first driving assembly for driving the baffles to move;

[0007] The baffle is divided into an open state and a closed state. In the open state, seawater can freely pass through the gap between two adjacent beams along the length direction of the first hook rod. As the first driving component drives the baffle to move, the baffle is pressed against the adjacent beams. Multiple baffles and adjacent beams form a water retaining wall, and the baffle is switched to a closed state.

[0008] Preferably, one side of the baffle is hinged to the crossbeam.

[0009] Preferably, the first driving assembly includes an articulated rod and a driving rod, one end of the articulated rod is hinged to the baffle, the other end of the articulated rod is hinged to the driving rod, the driving rod is vertically slidably connected to the floating island, and the driving rod is connected to a second driving assembly for driving its movement.

[0010] Preferably, the second driving assembly includes a slide, a spring and a hydraulic cylinder, the slide is fixedly connected to the driving rod, the spring is located between the slide and the floating island, the spring is used to drive the slide to move upward, the cylinder seat of the hydraulic cylinder is fixed on the floating island, the cylinder rod of the hydraulic cylinder is pressed against the slide, and the hydraulic cylinder is used to drive the slide to move downward.

[0011] Preferably, a buffer assembly is also provided on the floating island, and the buffer assembly includes a first hydraulic cylinder and a second hydraulic cylinder, the cylinder rod of the first hydraulic cylinder is used to push the slide seat to move downward, the floating island is fixedly connected to the second hydraulic cylinder, and a second hook rod for connecting to a ship or a dock is fixedly provided on the cylinder rod of the second hydraulic cylinder, the orientation of the second hook rod is consistent with that of the first hook rod, and the inner cavity of the second hydraulic cylinder is connected to the inner cavity of the first hydraulic cylinder; when the cylinder rod of the second hydraulic cylinder moves outward, the piston of the second hydraulic cylinder drives the hydraulic oil inside the second hydraulic cylinder to move to the inside of the first hydraulic cylinder and drives the cylinder rod of the first hydraulic cylinder to move downward.

[0012] Preferably, two buffer components are symmetrically arranged on the left and right.

[0013] Preferably, an elastic pad is provided on the cross beam, and in the closed state, the baffle is pressed against the elastic pad.

[0014] Preferably, the elastic pad is protruding from the surface of the cross beam, and in a closed state, the baffle is inclined toward a side close to the hinge rod.

[0015] Preferably, a stopper is fixedly provided at one end of the hinged rod away from the baffle, and the stopper is used to prevent the hinged rod from being out of contact with the driving rod.

[0016] Preferably, two anchoring assemblies are symmetrically arranged on the left and right.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] When the present invention is in use, the first hook rod is connected to the ship through an anchor cable. When the ship needs to be anchored, the baffle is controlled by the first driving component to close the interval between two adjacent beams. A plurality of baffles and adjacent beams form a water retaining wall. The baffle is switched to a closed state. Due to the presence of the water retaining wall, the resistance to the ship's movement is greatly increased. When the speed of the ship drops to a certain level, the floating island is connected to the dock.

[0019] Through the above structural arrangement, when wind and waves hit the ship, the ship drives the floating island to move through the anchor cable. Due to the presence of the retaining wall, the swaying of the ship is limited to a certain range. At the same time, the internal stress of the anchor cable is greatly reduced; thus, the mooring stability of the ship is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0030] Embodiment 1:

[0031] like Figure 1 , Figure 2 and Figure 6 As shown, this embodiment provides a mooring device, including a floating island 10, on which a first hook rod 27 for connecting a vessel or a dock is provided, and an anchoring assembly is provided at the lower side of the floating island 10, and the anchoring assembly includes a cantilever 11, a beam 12, and a baffle 13, wherein the cantilever 11 is fixedly connected to the floating island 10, and a plurality of beams 12 are provided in a linear array in a vertical direction and are all fixedly connected to the cantilever 11, and a baffle 13 for closing the interval between two adjacent beams 12 is provided, and one side of the baffle 13 is hinged to the beam 12, and the baffle 13 is connected to a first driving assembly for driving the baffle 13 to move;

[0032] like Figure 2 and Figure 3 As shown, specifically, the first driving assembly includes an articulated rod 14 and a driving rod 16, one end of the articulated rod 14 is hinged to the baffle 13, the other end of the articulated rod 14 is hinged to the driving rod 16, the driving rod 16 is vertically slidably connected to the floating island 10, the driving rod 16 is connected to a slide 20, the slide 20 is fixedly connected to the driving rod 16, a spring 22 is provided between the slide 20 and the floating island 10, the two ends of the spring 22 are respectively pressed against the floating island 10 and the slide 20, the spring 22 is used to drive the slide 20 to move upward, the cylinder seat of the hydraulic cylinder 26 is fixedly arranged on the floating island 10, the cylinder rod of the hydraulic cylinder 26 is pressed against the slide 20, and the hydraulic cylinder 26 is used to drive the slide 20 to move downward.

[0033] The baffle 13 is divided into an open state and a closed state. In the open state, seawater can freely pass through the gap between two adjacent beams 12 along the length direction of the first hook rod 27, the hydraulic cylinder 26 drives its cylinder rod to move, the slide 20 drives the drive rod 16 to move downward, the hinged rod 14 rotates relative to the drive rod 16, the hinged rod 14 drives the baffle 13 to rotate, the baffle 13 is pressed against the adjacent beams 12, and multiple baffles 13 and adjacent beams 12 form a water retaining wall, and the baffle 13 is switched to a closed state.

[0034] Furthermore, in order to further enhance the anchoring effect of the floating island 10, two anchoring assemblies are symmetrically arranged on the left and right. Since the baffle 13 is hinged to the beam 12, when the side of the baffle 13 close to the beam 12 is impacted, the hinge point between the baffle 13 and the beam 12 bears the impact force, and the baffle 13 is easier to detach from the beam 12; when the side of the baffle 13 close to the hinge rod 14 is impacted, the baffle 13 and the beam 12 as a whole bear the impact force; by arranging the anchoring assemblies symmetrically on the left and right, no matter from which direction the seawater impacts the baffle 13, the hinge point between the baffle 13 and the beam 12 does not need to bear the impact force, thereby ensuring the stable operation of the overall structure.

[0035] Embodiment 2:

[0036] The difference between this embodiment and the first embodiment is that a buffer component is added;

[0037] like Figure 2 and Figures 4 to 6 As shown, in order to facilitate the movement of the floating island 10 while ensuring the anchoring effect of the floating island 10, a buffer assembly is further provided on the floating island 10, and the buffer assembly includes a first hydraulic cylinder 23 and a second hydraulic cylinder 24, the cylinder rod of the first hydraulic cylinder 23 is used to push the slide 20 to move downward, the floating island 10 is fixedly connected to the second hydraulic cylinder 24, and a second hook rod 25 for connecting to a ship or a dock is fixedly provided on the cylinder rod of the second hydraulic cylinder 24, the orientation of the second hook rod 25 is consistent with that of the first hook rod 27, and the inner cavity of the second hydraulic cylinder 24 is connected to the inner cavity of the first hydraulic cylinder 23; when the cylinder rod of the second hydraulic cylinder 24 moves outward, the piston of the second hydraulic cylinder 24 drives the hydraulic oil inside the second hydraulic cylinder 24 to move to the inside of the first hydraulic cylinder 23 and drives the cylinder rod of the first hydraulic cylinder 23 to move downward.

[0038] When in use: (In the initial state, the cylinder rods of the first hydraulic cylinder 23, the second hydraulic cylinder 24 and the hydraulic cylinder 26 are all located at the innermost part thereof) The boat is connected to the second hook rod 25. When the boat is hit by wind and waves, the boat will shake with the sea water. During the shaking process of the boat:

[0039] When the ship moves away from the floating island 10, the internal stress of the anchor cable is relatively large, and the anchor cable drives the second hook rod 25 to move. The second hook rod 25 drives the piston to push the hydraulic oil into the first hydraulic cylinder 23 and pushes the slide 20 downward through the cylinder rod of the first hydraulic cylinder 23. The spring 22 is compressed, and the slide 20 drives the hinge rod 14 to move downward through the driving rod 16. The hinge rod 14 drives the baffle 13 to rotate and close the gap between the adjacent beams 12.

[0040] When the ship moves toward the floating island 10, the internal stress of the anchor cable is small, and the floating island 10 moves in the opposite direction due to the resistance of the seawater to the retaining wall. The baffle 13 opens under the impact of the seawater, and the baffle 13 drives the driving rod 16 and the slide seat 20 to move upward through the hinged rod 14. The spring 22 is reset, and the cylinder rods of the first hydraulic cylinder 23 and the second hydraulic cylinder 24 are reset.

[0041] Furthermore, in order to facilitate the movement of the floating island 10, two buffer assemblies are symmetrically arranged on the left and right. From the above description, it can be known that when one buffer assembly exists, the unidirectional movement of the floating island 10 can be controlled, and when two buffer assemblies are symmetrically arranged on the left and right, the bidirectional movement of the floating island 10 can be controlled. The moving direction of the floating island 10 can be controlled by connecting the anchor cable to the second hook rod 25 or the first hook rod 27.

[0042] Further, such as Figure 3 and Figure 7 As shown, an elastic pad 30 is provided on the cross beam 12. In the closed state, the baffle 13 is pressed against the elastic pad 30. Specifically, the baffle 13 is made of rubber. The elastic pad 30 is connected to the cross beam 12 by bolts. Since the elastic pad 30 is immersed in seawater for a long time, it needs to be replaced regularly to ensure its elasticity.

[0043] Furthermore, in order to facilitate the control of the opening of the baffle 13, the elastic pad 30 protrudes from the surface of the beam 12, and when in the closed state, the baffle 13 is inclined toward the side close to the hinge rod 14;

[0044] During actual use, since the side of the baffle 13 close to the beam 14 will be impacted by seawater, when the seawater impacts the side of the baffle 13 close to the beam 14, the seawater will move upward along the inclined surface of the baffle 13, thereby changing the direction in which the seawater impacts the floating island 10, thereby further weakening the impact force of the seawater on the floating island 10.

[0045] The above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the scope of protection required by the present invention.
