Example one

This embodiment provides a floating wave guard, which includes an upper float 2 and a lower float 1, as shown in fig. 1 to 5. The upper floating body 2 and the lower floating body 1 are rigidly connected through a connecting piece. The connecting piece can be a connecting plate 3 shown in fig. 1 or a connecting rod 6 shown in fig. 2. In fig. 2, the upper floating body 2 is connected with the lower floating body 1 through a plurality of connecting rods 6, so that the stable connection between the upper floating body 2 and the lower floating body 1 can be ensured.

In addition, the connecting plate 3 and the connecting rod 6 have the function of blocking wave energy in addition to connecting the upper floating body 2 and the lower floating body 1.

The floating wave preventing device comprises an upper floating body 2 connected above a lower floating body 1 besides the lower floating body 1. Compared with the conventional floating breakwater, the embodiment of the utility model provides an among the floating breakwater device, lower floater 1 submerges the degree of depth under the water deeper, and the ability that blocks the wave is stronger. Thus, the wave dissipating performance can be improved.

Specifically, the upper floating body 2 is made of a material having a relatively low specific gravity. Illustratively, the upper floating body 2 has a plastic or glass fiber reinforced plastic shell, and the interior of the plastic or glass fiber reinforced plastic shell is filled with a foam material. The upper floating body 2 may have a cylindrical shape, a square box shape, or other shapes, and is not particularly limited in the present invention. The volume of the upper float 2 may be smaller than that of the lower float 1.

The lower float 1 may be a tank. The lower floating body 1 can also adopt a glass fiber reinforced plastic shell, and can be provided with a steel skeleton supporting structure for supporting the glass fiber reinforced plastic shell. The cavity in the lower floating body 1 is filled with liquid. When the lower floating body 1 is shaken along with the waves, the liquid in the lower floating body 1 can shake along with the movement of the lower floating body 1, so that the movement of the lower floating body 1 is delayed, the shaking amplitude of the floating wave preventing device can be reduced, the stability of the floating wave preventing device is enhanced, and the wave eliminating capacity is improved.

In order to further improve the wave-breaking capacity of the enhanced floating wave-preventing device, a damping structure may be provided inside the lower floating body 1.

In an alternative embodiment, the damping structure comprises a damping plate 11 arranged inside the lower float 1. Specifically, a damping plate may be disposed between the upper bottom plate and the lower bottom plate in the cavity of the lower floating body 1, or damping plates may be disposed on two opposite side walls of the lower floating body 1. As shown in fig. 3, two damping plates 11 may be symmetrically arranged on two opposite side walls of the lower floating body 1, i.e. two damping plates 11 are arranged at the same height of the two side walls. The two damping plates 11 have a certain spacing between them, so that liquid can flow through the spacing back and forth. Note that the two damping plates 11 may be disposed asymmetrically. For example, one damping plate is provided at an upper portion of one side wall, and the other damping plate is provided at a lower portion of the other side wall. Through setting up the damping plate, can increase the damping that the internal liquid of lower floater rocked, reduce floating anti-wave device's the range of rocking to improve the unrestrained ability of weakening of reinforcing floating anti-wave device.

Specifically, the U-shaped plate 12 includes a bottom plate and side plates connected to both sides of the bottom plate, and has a U-shaped cross section. The two ends of the bottom plate and the two side plates are connected on the side wall of the lower floating body 1. A U-shaped space is formed between the U-shaped plate 12 and the lower floating body 1; the U-shaped space is filled with liquid. When the lower floating body shakes, the U-shaped plate can increase the damping of the liquid in the lower floating body to shake, and reduce the shaking amplitude of the floating wave preventing device, so that the wave dissipating capacity of the floating wave preventing device is improved.

The bottom of the lower floating body 1 is connected with a web plate 4 and a ribbed plate 5. The web plate 4 is rectangular and arranged along the length direction of the lower floating body 1, and rows of rib plates 5 are connected to two sides of the web plate 4. The rib plates 5 are triangular and arranged along the width direction of the lower floating body 1. One right-angle side of the rib plate 5 is connected with the web plate 4, and the other right-angle side is connected with the bottom of the lower floating body 1. The rib plates 5, the web plates 4 and the bottom of the lower floating body 1 form a semi-closed space, so that the formation and falling of water body vortex can be promoted, the wave energy consumption is increased, and the wave dissipating capacity of the floating wave-preventing device is improved.

The floating wave preventing device also comprises an anchoring structure. The anchoring structure is used for fixing the floating wave-preventing device. As shown in fig. 5, the mooring structure comprises two sets of anchor chain sets 7 and two tiebacks 8. Two anchor chain groups 7 are respectively connected to two opposite sides of the lower floating body 1. Each anchor set 7 comprises an upper secondary strand 71, a lower secondary strand 72 and a main strand 73. One end of the upper secondary chain 71 is connected to the upper part of the lower floating body 1, and the other end is connected to the head end of the main chain 73. One end of the lower auxiliary chain 72 is connected to the bottom of the lower floating body 1, and the other end is connected to the head end of the main chain 73. The tail end of the main chain 73 is connected with a corresponding anchorage 8. Both anchorages 8 are embedded in the seabed soil layer.

The utility model discloses utilized the mechanics principle of kite upper and lower acting line, buried anchor 8 underground in the seabed soil layer to be connected two sets of anchor chain group 7 with the anchor 8 that corresponds, reached the fixed action to anchor chain group 7. Because each anchor chain group 7 is connected with the corresponding anchor 8 through one main chain 73, when the anchor chain group 7 is fixed on the anchor 8, only the tail ends of the two main chains 73 are required to be fixed on the corresponding anchor 8, which is simpler and more convenient than the way of respectively fixing four anchor chains on the anchors 8. When the body needs to be disassembled, only two main chains 73 need to be separated from the anchorage 8, and obviously, compared with the method of separating four anchor chains from the anchorage 8 during the body disassembling, the method is more convenient, time-saving and labor-saving. In addition, in order to ensure the wave-breaking capacity of the floating wave-preventing device, the head ends of the upper secondary chains 71 in the two anchor chain groups 7 are respectively connected to two opposite side surfaces of the lower floating body 1, and the tail ends of the upper secondary chains 71 are connected with the head end of the main chain 73; meanwhile, the head ends of the lower auxiliary chains 72 in the two anchor chain groups 7 are respectively connected with the two sides of the bottom surface of the lower floating body 1, and the tail ends of the lower auxiliary chains 72 are connected with the head end of the main chain 73, so that the effect of stabilizing the floating wave preventing device is achieved, and the wave eliminating capability of the floating wave preventing device is ensured.

Because the hinge buckle bears pulling force from three directions of the upper auxiliary chain 71, the lower auxiliary chain 72 and the main chain 73, the damage rate of the hinge buckle is higher than that of the upper auxiliary chain 71, the lower auxiliary chain 72 and the main chain 73; in order to facilitate the replacement of the hinged buckle, each rotary structure part is composed of a semi-ring and a pin shaft; wherein, the both sides of the opening part of semi-ring are provided with a pinhole with round pin axle complex respectively and make round pin axle and semi-ring constitute the loop configuration. In order to facilitate the separation of the hinge buckles from the upper secondary chain 71, the lower secondary chain 72 and the main chain 73, the pin shaft and the half rings are detachably connected. In addition, in order to reduce the abrasion speed between the tail end chain ring of the upper auxiliary chain 71 and the pin shaft, the abrasion speed between the tail end chain ring of the lower auxiliary chain 72 and the pin shaft and the abrasion speed between the head end chain ring of the main chain 73 and the pin shaft in the wave dissipation process, a coaxial rotating matching mode is adopted among the pin shaft and the pin hole, so that the tail end chain ring of the upper auxiliary chain 71, the tail end chain ring of the lower auxiliary chain 72 and the head end chain ring of the main chain 73 rotate in the pin hole under the action of friction force when large friction force exists among the corresponding pin shafts, and the abrasion speed of the contact surfaces of the upper auxiliary chain 71, the lower auxiliary chain 72, the main chain 73 and the pin shaft is reduced.

In order to prevent the anchor chain group 7 from rusting on the premise of ensuring the strength of the anchor chain group 7, the two anchor chain groups 7 are both made of stainless steel materials.

In particular, since the upper and

lower sub-chains

71, 72 and the main chain 73 are constantly impacted by sea waves in water, links constituting the upper and

lower sub-chains

71, 72 and the main chain 73 are all set to be chain links having rounded edges in order to extend the service lives of the upper and

lower sub-chains

71, 72 and 73. The chain links with stops have a better strength than the chain links without stops and, compared to the chain links with edges, the smooth surface is obviously more impact-resistant.

The embodiment of the utility model provides a floating anti-wave device can the exclusive use, also can use after the interconnect, and floating anti-wave device has increased the last floating body on the body down, has increased this floating anti-wave device's the degree of depth of entry to the inner structure of body has been improved down, has increased the damping of the floating body down, has consequently improved the wave absorption ability of floating anti-wave device.

The wave-facing surface of the floating wave-preventing device comprises a side plate of an upper floating body, a side plate and a web plate of a lower floating body, and a connecting plate or a connecting rod between the upper floating body and the lower floating body.

Because the upper floating body is additionally arranged above the lower floating body, the lower floating body is deeper submerged, and the wave blocking capability is stronger. The lower floating body is filled with liquid, and a damping structure is additionally arranged, so that the shaking amplitude of the floating wave preventing device along with waves can be reduced, and the wave dissipating capacity of the floating wave preventing device is further improved.
