Description

Technical Field

[0001] The utility model relates to the technical field of anchoring of deep-sea aquaculture cages, in particular to a pile anchor with retractable wings. Background Art

[0002] Deep-sea aquaculture cages require cables and anchors to maintain their position and prevent them from being carried away by waves and currents. Typically, these cages are anchored similarly to traditional ships, using seabed piles or gravity anchors, connecting the cables and anchors directly. Seabed piles, known as pile anchors, are currently the primary method for securing deep-sea aquaculture cages.

[0003] Currently, pile anchors are typically cylindrical or square-shaped, primarily made of wood, concrete, or steel, and driven into the seabed using a pile driver. In softer soil, simple cylindrical and square-piled anchors have limited contact area and friction with the soil and sand, resulting in a low tensile force that the anchors can withstand. This makes them inadequate for resisting external forces such as wind, tides, and waves, making them susceptible to being pulled out by wind and waves, potentially washing away the cages.

[0004] Existing technologies incorporate fixed wing panels at the rear of the pile anchor body. While this increases the contact area between the pile anchor and the soil and sand, the wing panels are located at the rear and not buried deep enough, improving pullout resistance to a certain extent. They are still susceptible to being pulled out by strong waves. To achieve deeper burial and greater friction, some solutions incorporate wing panels in the middle of the pile anchor body or near the pile tip. However, this arrangement makes piling difficult and can lead to damage to the fixed wing panels during driving, significantly increasing installation difficulty and cost. To address the installation issues caused by installing wing panels in the middle, another solution incorporates retractable wing panels. During piling, the wing panels are retracted and tightly surround the pile anchor. After being fully driven, they are unfolded when the pile anchor is pulled, increasing the contact area between the pile anchor and the soil and sand, thereby enhancing the pullout resistance of the pile anchor. However, this arrangement suffers from the problem that the retracted wing panels cannot be deployed within the soil and sand, and thus cannot fully achieve the desired pullout resistance. Utility Model Content

[0005] Based on this, an object of the present invention is to provide a pile anchor with retractable wings.

[0006] A pile anchor with retractable wings comprises: a pile anchor body, a plurality of retractable wings, the retractable wings being movably connected to the middle outer wall of the pile anchor body and being rotatably retractable along a direction perpendicular to the axis of the pile anchor body toward a direction parallel to the axis of the pile anchor body, wherein when the retractable wings are retracted, the surface opposite to the outer wall of the pile anchor body is the top surface of the retractable wings, and the surface opposite to the top surface of the retractable wings is the bottom surface of the retractable wings; and an anti-closing component is arranged between the retractable wings and the pile anchor body to prevent the retractable wings from adhering to the middle outer wall of the pile anchor body.

[0007] Furthermore, the blocking component is a blocking block, which is fixedly arranged on the top surface of the retractable wing; or the blocking block is fixedly arranged on the outer wall of the pile anchor body opposite to the top surface of the retractable wing when the retractable wing is retracted.

[0008] Furthermore, the blocking member is a spring, one end of which is fixedly arranged on the top surface of the foldable wing, and the other end of which is fixedly arranged on the outer wall of the pile anchor body opposite to the top surface of the foldable wing when the foldable wing is folded.

[0009] Furthermore, the blocking member is a spring, one end of which is fixedly arranged on the bottom surface of the foldable wing, and the other end of which is fixedly arranged on the outer wall of the pile anchor body opposite to the bottom surface of the foldable wing when the foldable wing is unfolded.

[0010] Furthermore, two retractable wings may be symmetrically arranged along the same cross section of the pile anchor body, or three or more retractable wings may be evenly arranged at equal intervals.

[0015] Compared with the prior art, the pile anchor with retractable wings of the present invention has the following beneficial effects:

[0016] 1) Through the synergistic effect of the retractable wings provided in the middle of the pile anchor body and the blocking member provided between the retractable wings and the pile anchor body, the pile anchor can be easily driven into the soil or sand. The retractable wings buried deeper can be opened, so that the pile anchor has a larger contact area and greater friction with the soil or sand, thereby improving the pull-out resistance of the pile anchor in the soil or sand, effectively resisting wind and waves, extending the service life, and effectively reducing the installation cost and use cost of the pile anchor.

[0017] 2) The pile anchor's gripping ability can be further enhanced by staggered arrangement of multiple retractable wings in the middle of the pile anchor body.

[0018] 3) By providing a support unit at the bottom of the foldable wing, the service life of the foldable wing can be further extended, thereby ensuring that the pile anchor has stable pull-out resistance.

[0019] 4) The radial anti-slip frame arranged at the tail of the pile anchor body can effectively connect with the connection part of the breeding box to prevent the connection part from slipping or sliding. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention.

[0026] In order to solve the problem that when existing pile anchors are provided with retractable wing plates, they cannot be unfolded after being driven into soil or sand, resulting in the wing plates being unable to increase the contact area with the soil or sand and affecting their pull-out resistance; after research, design, testing and verification, the utility model proposes a pile anchor with retractable wing plates.

[0027] See also Figures 1 to 3 The pile anchor of the present invention includes a pile anchor body 10, a plurality of retractable wings 20 movably connected to the outer wall of the pile anchor body 10, and a blocking member 30 arranged between the retractable wings and the pile anchor body 10, wherein the retractable wings can be rotated and retracted along a direction perpendicular to the axis of the pile anchor body to a direction parallel to the axis of the pile anchor body, and the blocking member 30 prevents the retractable wings from contacting the outer wall of the pile anchor body 10.

[0028] In a specific implementation, the pile anchor body 10 is a cylindrical or square column, which includes a tail, a middle and a tip, and is further selected as a solid column to improve the compressive strength.

[0029] For example, the pile anchor body 10 is configured as a cylinder with a length of more than 2 meters and a diameter of more than 8 centimeters, and its material is selected from 45# steel, 304 stainless steel, or 316 stainless steel.

[0030] The rear end of the pile anchor body 10 is provided with an anti-slip frame 11. The anti-slip frame 11 is composed of a plurality of slender columns 112 arranged radially about the axis of the pile anchor body 10. The plurality of slender columns 112 are arranged radially on different cross-sections of the pile anchor body 10 when viewed from above. The shackle 1 is arranged between the different slender columns 112 to prevent the shackle 1 from slipping or sliding off the pile anchor body 10. Exemplarily, the anti-slip frame 11 includes a first slender column 112A and a second slender column 112B. The first slender column 112A and the second slender column 112B extend perpendicularly through the pile anchor body 10 and are arranged on different cross-sections. The first slender column 112A and the second slender column 112B have dimensions of 10 cm x 8 cm x 4 cm.

[0031] Furthermore, the plurality of slender columns 112 can be arranged radially on the same cross-section of the pile anchor body 10. The slender columns 112 can have a circular ring shape at one end, with the other end fixedly connected to the outer wall of the pile anchor body 10. The slender columns 112 can also have circular ring shapes at both ends, with the slender columns 112 extending through the cross-section of the pile anchor body 10. The shackle 1 is buckled into the ring of the circular slender columns 112 and is firmly connected to the pile anchor body 10. The tip of the pile anchor body 10 is provided with a pile tip 12, which is in the shape of a flat cone or a blunt axe blade, making it easier for the entire pile anchor to be driven into soil or sand.

The retractable wings 20 are movably connected to the outer wall of the pile anchor body 10, allowing them to be retracted toward the axial direction of the pile anchor body 10 or deployed perpendicular to the axial direction of the pile anchor body 10, forming a state where they are retracted toward the pile anchor body 10 and deployed away from the pile anchor body 10. When retracted, the surface of the retractable wings 20 facing the outer wall of the pile anchor body 10 is the top surface of the retractable wings, and the surface opposite the top surface of the retractable wings is the bottom surface of the retractable wings.

[0033] Furthermore, the foldable wing 20 is a plate-type wing, preferably a rectangular plate of (35-40) cm × (12-15) cm × 0.8 cm; the foldable wing 20 can also be a blade-type fan or other shapes that are easy to unfold and fold, and have sufficient area.

[0034] Furthermore, two retractable wings may be symmetrically arranged along the same cross section of the pile anchor body 10, or three or more retractable wings may be evenly spaced along the circumference of the cross section. When two retractable wings are symmetrically arranged, the two retractable wings may be hinged to the outer wall of the pile anchor body 10 via a common pin extending through the pile anchor body 10.

[0035] Furthermore, a plurality of retractable wings disposed on the same cross-section of the pile anchor body 10 constitute a retractable wing group 20'. Multiple retractable wing groups 20' may be disposed along different cross-sections of the pile anchor body 10, with adjacent retractable wing groups 20' being staggered. For example, two retractable wing groups 20' are disposed sequentially from top to bottom in the middle portion of the pile anchor body 10. One retractable wing group 20'A comprises two symmetrically disposed retractable wings, and the other retractable wing group 20'B also comprises two symmetrically disposed retractable wings. The retractable wing groups 20'A and 20'B are vertically staggered. If a further retractable wing group 20'C is added, the retractable wing group 20'C is disposed vertically staggered with the retractable wing group 20'B.

[0036] Furthermore, to enhance the foldable wings' pressure resistance and effectively withstand the pressure of soil and sand, support units 21 are provided on their undersides. These support units 21 consist of several support ribs that are parallel to the axial direction of the foldable wings and evenly distributed across their undersides. These support units 21 also comprise a support net that covers the underside of the foldable wings.

[0037] The blocking member 30 is provided between the retractable wings and the pile anchor body 10 to prevent the retractable wings from adhering to the outer wall of the pile anchor body 10 and being unable to unfold in soil or sand.

[0038] In one embodiment, the blocking member 30 is a blocking block fixedly mounted on the top surface of the retractable wing; or fixedly mounted on the outer wall of the pile anchor body opposite the top surface of the retractable wing when the retractable wing is retracted. Preferably, the blocking block is positioned near the rotational position of the retractable wing.

[0039] Furthermore, the blocking member 30 is a small cylindrical block or a small square column block, and the size of the small cylindrical block or the small square column block is preferably: 10 cm in length and 1 to 2 cm in diameter.

[0040] Furthermore, the blocking member 30 is an inverted triangle block, and the size of the inverted triangle block is preferably: a long side of 15 cm, a height of 5 to 6 cm, and a thickness of 3 to 4 cm.

[0041] In another embodiment, the blocking member 30 is a spring, and the spring can be disposed on the top surface of the foldable wing or on the bottom surface of the foldable wing.

[0042] When the spring is arranged on the top surface of the foldable wing, one end of the spring is fixed on the top surface of the foldable wing, and the other end is fixed on the outer wall of the pile anchor body 10 opposite to the top surface of the foldable wing when the foldable wing is folded.

[0043] When the spring is arranged on the bottom surface of the foldable wing, one end of the spring is fixed on the bottom surface of the foldable wing, and the other end is fixed on the outer wall of the pile anchor body 10 opposite to the bottom surface of the foldable wing when the foldable wing is unfolded.
