Description

Technical Field

[0001] The present invention relates to the technical field of floating towers, and in particular to an offshore annular floating tower. Background Art

[0002] The offshore floating tower can undertake the function of ocean signal transmission, and at the same time it can form floating land in a certain area, which is convenient for the placement of other equipment, such as wind power testing equipment.

[0003] Compared with ordinary floating towers, annular floating towers have smooth edges of floating parts and stronger wave resistance, so most modern offshore floating towers use annular tower bodies.

[0004] Most of these offshore annular floating towers used for marine signal transmission and wind test equipment installation need to be anchored in place using anchor bodies. The most commonly used method is the figure-eight anchoring, in which two anchor bodies are thrown out from both sides, so that a certain angle is formed between the anchor chains or anchor ropes. In actual use, as the tide changes, the distance between the floating tower and the seabed changes. At this time, the anchor chains, anchor ropes, etc. will become loose. At the same time, as the ocean currents and waves act on the floating tower, the floating tower will drift. During this process, the anchor chains or anchor ropes will easily become entangled. Once these anchor chains and anchor ropes become entangled, they cannot be untied well. Generally, one of the anchor bodies or all of them are abandoned, which increases the cost of use.

[0037] Also includes:

[0038] Bidirectional anchoring mechanism 5, see Figure 2-Figure 4 As shown, the bidirectional anchoring mechanism 5 is arranged at the bottom end of the floating tower base 1, and the bidirectional anchoring mechanism 5 includes an anchoring rope assembly 51, a recovery assembly 52 and a rope body support assembly 53. The bottom end of the floating tower base 1 is hollow, and two recovery assemblies 52 are provided, and are respectively arranged on both sides of the hollow chamber at the bottom end of the floating tower base 1. Two anchoring rope assemblies 51 are correspondingly provided, and are respectively connected to the two recovery assemblies 52, and the two anchoring rope assemblies 51 pass through the bottom end of the floating tower base 1. The rope body support assembly 53 is arranged at the edge where the anchoring rope assembly 51 passes through the bottom wall of the floating tower base 1, and the rope body support assembly 53 acts on the part of the anchoring rope assembly 51 passing through the floating tower base 1, so as to guide and support the rope body of the anchoring rope assembly 51, and prevent the rope body from rubbing at the position where it passes through the floating tower base 1;

[0039] The synchronous shielding mechanism 6 is arranged at the bottom end of the floating tower base 1, and the synchronous shielding mechanism 6 is connected to the recovery component 52, so that when the recovery component 52 recovers the anchor rope component 51, it can drive the synchronous shielding mechanism 6 to shield the anchor rope component 51 and keep it away from the anchor rope component 51 on the other side to prevent the anchor rope component 51 from being entangled.

[0040] The floating tower base 1 includes two layers, the upper layer of the floating tower base 1 is hollow, and the lower layer of the floating tower base 1 is an arc-shaped bottom. The arc-shaped bottom of the floating tower base 1 can reduce the impact of ocean currents on the bottom of the floating tower base 1, and the arc-shaped bottom can keep the anchor rope assembly 51 tilted outward when passing through the bottom of the floating tower base 1, so that the two anchor rope assemblies 51 tend to move away from each other, thereby separating the anchor rope assemblies 51. The recovery assembly 52 includes a positioning seat 521, a working motor 522 and a winding shaft 523. The positioning seat 521 is arranged in the hollow upper layer of the floating tower base 1, and the winding shaft 523 is rotatably installed on the positioning seat 521. The working motor 522 is arranged on one side of the positioning seat 521, and the winding shaft 523 is connected to the output end of the working motor 522. The working motor 522 is controlled by a circuit. The working state of the working motor 522 can be controlled, so that when the distance between the floating tower base 1 and the seabed changes due to the effect of the tide, the working motor 522 can be controlled to control the winding shaft 523 to wind up the anchor rope assembly 51, so as to control the anchor rope assembly 51 to keep it in a taut state, and to avoid the entanglement caused by the looseness of the anchor rope assembly 51 to a certain extent. The anchor rope assembly 51 passes through the upper and lower layers of the floating tower base 1 and is connected to the winding shaft 523, so that the working motor 522 can drive the winding shaft 523 to wind up the anchor rope assembly 51, and can tighten the rope body part of the anchor rope assembly 51 when the anchor rope assembly 51 is lowered and anchored, thereby reducing the rope body length between the floating tower base 1 and the anchor point, so as to reduce the moving radius of the floating tower base 1 when floating.

[0041] The synchronous shielding mechanism 6 includes a clutch device body 61, a linkage rod assembly 62 and a shielding assembly 63. The shielding assembly 63 is arranged at the edge of the anchor rope assembly 51 passing through the lower layer of the floating tower base 1. The clutch device body 61 is arranged at the end of the winding shaft 523 passing through the positioning seat 521. The linkage rod assembly 62 is arranged between the clutch device body 61 and the shielding assembly 63. The clutch device body 61 forms a connection and clutch effect between the winding shaft 523 and the linkage rod assembly 62, and can drive the linkage rod assembly 62 to rotate through the winding shaft 523. At the same time, in the process of driving the linkage rod assembly 62 to rotate, the separation of the connection can be controlled as needed to control the rotation of the linkage rod assembly 62. The clutch device body 61 is a common clutch structure, which is not repeated here, so that when the winding shaft 523 rotates, the shielding assembly 63 can be driven by the linkage effect of the clutch device body 61 and the linkage rod assembly 62 to form an extrusion shielding of the anchor rope assembly 51.

[0042] The linkage rod assembly 62 includes a linkage gear set 621, a linkage through rod 622 and a driving gear rod 623. The driving gear rod 623 is rotatably installed on the lower layer of the floating tower base 1. The linkage through rod 622 passes through the upper and lower layers of the floating tower base 1, and one end of the linkage through rod 622 is close to the clutch device body 61, and the other end is close to the driving gear rod 623. The linkage gear sets 621 are grouped into two, which are respectively arranged at the ends of the linkage through rod 622 close to the clutch device body 61 and the driving gear rod 623, so that the rotation of the clutch device body 61 can drive the driving gear rod 623 to rotate;

[0043] Among them, the driving gear rod 623 includes a rotating rod and a gear plate. The rotating rod is horizontally installed on the lower layer of the floating tower base 1. The gear plates are arranged at both ends of the rotating rod, and the gear plates act on the shielding component 63. The linkage gear group 621 is arranged in the middle of the rotating rod and between the linkage through rod 622.

[0044] The shielding assembly 63 includes a mounting boss 631, a rotating shielding plate 632 and a linkage tooth surface 633. The mounting boss 631 is arranged at the edge of the position where the anchor rope assembly 51 passes through the lower layer of the floating tower base 1. The rotating shielding plate 632 is rotatably mounted on the mounting boss 631 through an axle, and one end of the rotating shielding plate 632 passes through the lower bottom wall of the floating tower base 1. The plate body of the rotating shielding plate 632 passing through the lower bottom wall of the floating tower base 1 is a metal plate body in the style of a fence, which can reduce the resistance when rotating in seawater. The linkage tooth surface 633 is arranged on the side of the rotating shielding plate 632 close to the gear sheet of the driving gear rod 623, so that when the gear sheet of the driving gear rod 623 rotates, it can drive the linkage tooth surface 633 and the rotating shielding plate 632 to rotate with the mounting boss 631 as the axis, so that the other end of the rotating shielding plate 632 rotates and approaches one side of the anchor rope assembly 51.

[0045] Among them, the side of the linkage tooth surface 633 close to the gear piece of the driving gear rod 623 is an arc surface, and the angle corresponding to the arc surface is an acute angle. A tooth block corresponding to the gear piece of the driving gear rod 623 is arranged on the acute-angle arc surface of the linkage tooth surface 633. When the linkage tooth surface 633 rotates to the edge and is close to the bottom wall of the floating tower base 1 under the drive of the gear piece of the driving gear rod 623, under the clutch action of the clutch device body 61, the drive of the linkage tooth group 621 and the linkage through rod 622 can be stopped. At this time, the driving gear rod 623 stops, so that the linkage tooth surface 633 remains in a state of being in contact with the bottom wall of the floating tower base 1. At this time, the linkage tooth surface 633 and the rotating shielding plate 632 will maintain the rotation angle and continue to shield the anchor rope assembly 51.

[0046] like Figure 8As shown, the lower end of the plate body of the rotating shielding plate 632 passing through the floating tower base 1 is arc-shaped, so that when the rotating shielding plate 632 is rotated to a vertical direction under the floating tower base 1, the arc-shaped plate body can reduce the impact of ocean currents on the rotating shielding plate 632, thereby reducing the impact of ocean currents on the floating tower base 1. At the same time, the arc-shaped plate body can reduce the friction between the anchor rope assembly 51 and the plate body when shielding the anchor rope assembly 51, thereby reducing wear.

[0047] The anchoring rope assembly 51 includes a connecting rope 511 and a bottom anchor 512. One end of the connecting rope 511 is connected to the reel 523, and the other end passes through the upper and lower sides of the floating tower base 1 and is located outside the bottom end of the floating tower base 1. The bottom anchor 512 is arranged on the side of the connecting rope 511 away from the reel 523.

[0048] Among them, the lower layer of the floating tower base 1 is provided with two arc-shaped pipes with outlets inclined outward, and the connecting rope 511 passes through the arc-shaped pipe of the lower layer of the floating tower base 1. When the two connecting ropes 511 pass through the two arc-shaped pipes respectively, the two connecting ropes 511 will remain in an inclined outward state when passing out, so that the connecting ropes 511 of the two anchoring rope assemblies 51 remain away from each other in the lower layer of the floating tower base 1, and then through the shielding effect of the shielding assembly 63 and the guiding effect of the arc-shaped pipe, the connecting ropes 511 of the two anchoring rope assemblies 51 are effectively separated to prevent the connecting ropes 511 from getting close and entangled.

[0049] The rope body supporting assembly 53 includes a base 531, a supporting rotating frame 532, a torsion spring 533 and an auxiliary buffer assembly 7. The base 531 is arranged at the edge where the connecting rope 511 passes through the upper bottom wall of the floating tower base 1. The supporting rotating frame 532 is rotatably installed on the base 531, and the supporting end of the supporting rotating frame 532 is in contact with the connecting rope 511. The torsion spring 533 is arranged at the connection between the supporting rotating frame 532 and the base 531. The auxiliary buffer assembly 7 is arranged below the supporting rotating frame 532, and the auxiliary buffer assembly 7 acts on the swing arm of the supporting rotating frame 532.

[0050] Among them, the supporting rotating frame 532 includes a rotating arm installed on the base seat 531 for horizontal rotation and a supporting block arranged at the end of the rotating arm. The supporting block fits the connecting rope 511, and the middle of the supporting block is concave. When the connecting rope 511 is wound, as the winding shaft 523 is wound, the connecting rope 511 will be displaced on the supporting block. The concave in the middle of the supporting block can guide the connecting rope 511 to keep sliding toward the middle part of the supporting block, and can limit the sliding of the connecting rope 511 in the concave part of the supporting block to prevent the connecting rope 511 from slipping off.

[0051] Further, the auxiliary buffer assembly 7 includes an auxiliary base 701, a shock absorbing arm 702 and a reset spring 703. The auxiliary base 701 is arranged on the upper bottom wall of the floating tower base 1, and the auxiliary base 701 is located below the supporting rotating frame 532. The shock absorbing arm 702 is rotatably mounted on the auxiliary base 701, and the end of the shock absorbing arm 702 away from the auxiliary base 701 is rotatably connected to the rotating arm part of the supporting rotating frame 532. The reset spring 703 is arranged at the connection between the shock absorbing arm 702 and the auxiliary base 701.

[0052] Among them, the shock-absorbing arm 702 includes a telescopic rod and a shock-absorbing spring arranged between the telescopic rods. One end of the telescopic rod is installed on the auxiliary base 701 by rotating horizontally through an axis, and the other end is rotatably connected to the rotating arm part of the supporting rotating frame 532, so that when the rotating arm of the supporting rotating frame 532 rotates, the telescopic rod and the shock-absorbing spring that squeeze the shock-absorbing arm 702 are compressed to form a shock-absorbing effect, which can form a supporting effect on the connecting rope 511 when the connecting rope 511 is reeled in, prevent the connecting rope 511 from rubbing at the position where it passes through the upper bottom wall of the floating tower base 1, and ensure the safety of the rope body of the connecting rope 511.

[0053] In this embodiment, when the floating tower base 1 floats on the sea surface, one of the working motors 522 can be controlled to start, and the connecting rope 511 and the bottom anchor 512 on the winding shaft 523 can be lowered, so that a bottom anchor 512 at the bottom of the floating tower base 1 completes bottoming and anchoring. After the floating tower base 1 floats a certain distance, another working motor 522 is started, so that the other connecting rope 511 and the bottom anchor 512 are hung down and anchored at the bottom of the floating tower base 1, forming an eight-shaped anchoring for the floating tower base 1. After completion, the two working motors 522 can be started to reverse, and the connecting rope 511 can be wound up to tighten the two connecting ropes 511. In the process of winding up the connecting rope 511 to adjust its length, when the working motor 522 drives the winding shaft 523 to rotate, the clutch device body 61 will rotate synchronously with the winding shaft 523, driving the linkage gear group 621 and the linkage through rod 622 to rotate, thereby driving the driving gear rod 623 at the other end of the linkage through rod 622 to rotate. The gear plate of the driving gear rod 623 is used to drive the rotating baffle plate 632 to rotate on the mounting protrusion 631, so that the rotating baffle plate 632 is rotated to the side close to the connecting rope 511 to form a shield for the connecting rope 511. When the rotating baffle plate 632 rotates to the outermost edge, under the clutch action of the clutch device body 61, the driving of the linkage gear group 621 and the linkage through rod 622 is stopped. At this time, the rotating baffle plate 632 maintains the shielding state of the connecting rope 511, and the two connecting ropes 511 are respectively shielded by the two rotating baffle plates 632. When the working motor 522 drives the winding shaft 523 to rotate, rewind and tighten the connecting rope 511, the two connecting ropes 511 can be separated. Through the dual effects of tightening the connecting rope 511 and using the rotating baffle plate 632 to shield the connecting rope 511, the entanglement of the connecting rope 511 is effectively reduced, the cost is reduced, and at the same time, the stability of the two anchoring rope assemblies 51 when forming an octagonal anchor on the floating tower base 1 is ensured.
