DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0043] Reference Figures 1 to 6 As shown, an embodiment of the present invention provides a mooring anchor, comprising an anchor rod 10, an anchor claw 20 and an anchor chain 30; the anchor rod 10 is a hollow structure, and has a receiving cavity 101 for fixing a pile driver 40; the anchor claw 20 is hinged to at least the outer surface of the anchor rod 10, and the anchor claw 20 has a first relative position and a second relative position relative to the anchor rod 10; along the axial direction of the anchor rod 10, the projection area of ​​the anchor claw 20 when it is in the first relative position is greater than the projection area of ​​the anchor claw 20 when it is in the second relative position; one end of the anchor chain 30 is connected to the anchor rod 10, and the other end of the anchor chain 30 is used to connect to a floating body on the water surface.

[0044] Specifically, if Figures 1 to 6As shown, the mooring anchor includes an anchor rod 10, an anchor claw 20 and an anchor chain 30. The anchor claw 20 is arranged on the outer side of the anchor rod 10. The anchor rod 10 is connected to the water surface floating body through the anchor chain 30. Under the traction of the anchor chain 30 and the water surface floating body, the anchor claw 20 can achieve good anchoring with the soil layer, thereby realizing reliable mooring of the water surface floating body. Photovoltaic brackets, photovoltaic modules, wave power generation devices and other power generation equipment can be arranged on the water surface floating body. The cross-sectional shape of the water surface floating body can be a prism, a cylinder, a hemisphere, etc., and the cross section can be a uniform cross section or a variable cross section.

[0045] The anchor rod 10 is a hollow structure with a receiving cavity 101. During construction, the pile driver 40 can be inserted into the receiving cavity 101 of the anchor rod 10 to achieve fixation. The pile driver 40 drives the anchor rod 10 and the anchor claw 20 to move, so that the anchor rod 10 and the anchor claw 20 extend into the preset depth in the soil layer. The anchor rod 10 and the anchor claw 20 are fixed under the action of the soil layer pressure. The preset depth can be calculated by combining the structure of the underwater geological layer through the preliminary engineering geological survey. Compared with the traditional gravity anchor, the mooring anchor of the embodiment of the present invention is not easy to shift because it extends into the soil layer, and has better reliability. The pile driver 40 can be operated using a pile driving ship, a pile driving platform, etc. The pile driver 40 itself is a steel pipe pile structure, and the anchor chain 30 can pass through the pile driver 40 without affecting the pile driver 40 extending into the receiving cavity 101 of the anchor rod 10.

[0046] The fluke 20 is hinged to the outer surface of the anchor rod 10, and the number of flukes 20 can be two, three, four, etc. In the embodiment of the present invention, four flukes 20 are arranged on the outer surface of the anchor rod 10, and the four flukes 20 are symmetrically arranged and evenly distributed on the outer surface of the anchor rod 10, so that the force is more evenly applied. The fluke 20 can be switched between the first relative position and the second relative position by relative rotation with the anchor rod 10. When the fluke 20 is in the first relative position, the fluke 20 is in an open state relative to the anchor rod 10, and when the fluke 20 is in the second relative position, the fluke 20 is in a retracted state relative to the anchor rod 10. Along the axial direction of the anchor rod 10, the projection area of ​​the fluke 20 when it is in the first relative position is greater than the projection area of ​​the fluke 20 when it is in the second relative position.

[0047] During construction, the pile driver 40 drives the anchor rod 10 and the anchor claw 20 to extend into the soil layer. Under the pressure of the soil layer, the anchor claw 20 is forced to retract to the second relative position, with a smaller projected area, which is convenient for the anchor rod 10 and the anchor claw 20 to extend into the soil layer. After the anchor rod 10 and the anchor claw 20 extend into the soil layer to a preset depth, the pile driver 40 is withdrawn, and the anchor chain 30 slowly applies tension. Under the pressure of the soil layer and the tension of the anchor chain 30, the anchor claw 20 will open to the first relative position, with an increased projected area, and the anchor claw 20 will fit closely with the soil layer, increasing the force, and the greater the tension applied by the surface float and the anchor chain 30, the greater the tension on the anchor claw 20, which reduces the risk of dragging the anchor and improves the reliability of the mooring.

[0048] The anchor chain 30 and the anchor rod 10 can be fixed by welding, clamping, etc. For example, a ring structure can be provided at the end of the anchor rod 10, and the anchor chain 30 is assembled with the anchor rod 10 through the ring structure. The anchor chain 30 can be an iron chain, or it can be made of other corrosion-resistant and pulling-resistant materials.

[0049] In the embodiment of the present invention, when mooring a floating body on the water surface, the pile driver 40 can be used to send the mooring anchor into the soil layer at a preset depth, and the anchor claw 20 can be firmly embedded in the soil layer, which greatly increases the anchoring force, reduces the risk of anchoring, and improves the reliability of mooring. In addition, when the pile driver 40 sends the mooring anchor into the soil layer, the anchor claw 20 shrinks to the second relative position under the pressure of the soil layer, and the projection area along the axial direction of the anchor rod 10 is small, which is convenient for the mooring anchor to enter the soil layer; after the mooring anchor reaches the preset depth in the soil layer, the pile driver 40 is removed, and under the pulling of the anchor chain 30 and the pressure of the soil layer, the anchor claw 20 opens to the first relative position, and the projection area along the axial direction of the anchor rod 10 is large, which further improves the anchoring force.

[0050] Optionally, refer to Figure 5 As shown, a clamping portion 102 is provided on the side wall of the accommodating cavity 101 , and the clamping portion 102 is used to clamp with the pile driver 40 .

[0051] Specifically, if Figure 5 As shown, the pile driver 40 adopts a cylindrical structure, and a snap-fitting part is arranged at the bottom of the pile driver 40. The pile driver 40 applies force to the mooring anchor by using the snap-fitting part 102 of the side wall of the accommodating cavity 101 and the snap-fitting part. The snap-fitting part 102 can be in the shape of a convex block symmetrically arranged on the side wall of the accommodating cavity 101. A contracted boss structure is arranged at the bottom of the pile driver 40, and the boss structure is snap-fitted with the boss, so that the pile driver 40 can drive the mooring anchor to move into the soil layer.

[0052] Optionally, refer to Figure 1 and Figure 2 As shown, along the axial direction of the anchor rod 10 , both ends of the accommodating cavity 101 are provided with expansion structures 103 , and the projection area of ​​the expansion structure 103 away from the accommodating cavity 101 is larger than the projection area of ​​the expansion structure 103 close to the accommodating cavity 101 .

[0053] Specifically, if Figure 1 and Figure 2As shown, in order to facilitate the pile driver 40 and the anchor chain 30 to extend into the accommodating cavity 101, expansion structures 103 are provided at both ends of the accommodating cavity 101 along the axial direction of the anchor rod 10. The projected area of ​​the expansion structure 103 away from the accommodating cavity 101 is larger than the projected area of ​​the expansion structure 103 close to the accommodating cavity 101. The pile driver 40 and the anchor chain 30 can be smoothly assembled with the anchor rod 10 through the expansion structure 103. At the same time, the expansion structure 103 can also play a certain guiding role, reducing the difficulty of assembling the pile driver 40 and the accommodating cavity 101 and improving the construction efficiency.

[0054] After the anchor rod 10 and the anchor claw 20 extend into the soil layer to a preset depth, the pile driver 40 is pulled out. If the diameter of the pile driver 40 is too large, the hole is backfilled and compacted in situ after being pulled out.

[0055] Optionally, refer to Figures 1 to 5 As shown, the anchor rod 10 includes: a main body 104 and an auxiliary entrapment device 105, the accommodating cavity 101 is arranged in the main body 104; the auxiliary entrapment device 105 is arranged on a side of the main body 104 away from the anchor chain 30; the auxiliary entrapment device 105 is hinged with the anchor claw 20; along the axial direction of the anchor rod 10, the projection area of ​​the auxiliary entrapment device 105 away from the main body 104 is smaller than the projection area of ​​the auxiliary entrapment device 105 close to the main body 104; the auxiliary entrapment device 105 has a first position and a second position relative to the main body 104, wherein the first position is the position of the auxiliary entrapment device 105 close to the main body 104, and the second position is the position of the auxiliary entrapment device 105 away from the main body 104; when the auxiliary entrapment device 105 is in the first position, the anchor claw 20 is in the first relative position; when the auxiliary entrapment device 105 is in the second position, the anchor claw 20 is in the second relative position.

[0056] Specifically, if Figures 1 to 5 As shown, the anchor rod 10 includes a main body 104 and an auxiliary burying device 105. The auxiliary burying device 105 has a smaller projected area than the main body 104. In an embodiment of the present invention, the auxiliary burying device 105 can be a pointed structure, which can smoothly break the soil layer when the mooring anchor enters the soil layer, thereby improving construction efficiency.

[0057] The anchor claw 20 can switch between the first relative position and the second relative position by relative rotation with the anchor rod 10. Specifically, the switching can be achieved only by the soil pressure and the tension of the anchor chain 30. For example, the pile driver 40 drives the anchor rod 10 and the anchor claw 20 to extend into the soil layer. Under the action of the soil pressure, the anchor claw 20 is forced to retract to the second relative position; after the anchor rod 10 and the anchor claw 20 extend into the soil layer to a preset depth, the pile driver 40 is withdrawn, the anchor chain 30 slowly applies tension, and the anchor claw 20 will open to the first relative position under the action of the soil pressure and the tension of the anchor chain 30.

[0058] The anchor claw 20 is hinged to the auxiliary burying device 105, and the anchor claw 20 switches between the first relative position and the second relative position, and can also be switched by the auxiliary burying device 105. The auxiliary burying device 105 has a first position and a second position relative to the main body 104, wherein the first position is the position of the auxiliary burying device 105 close to the main body 104, and the second position is the position of the auxiliary burying device 105 away from the main body 104. When the auxiliary burying device 105 is in the first position, the anchor claw 20 is in the first relative position; when the auxiliary burying device 105 moves to the second position, it will drive the anchor claw 20 to be in the second relative position.

[0059] The switching of the auxiliary earth-entering device 105 between the first position and the second position can be controlled by the action of the pile driver 40 and the anchor chain 30. When the pile driver 40 sends the mooring anchor into the soil layer, the auxiliary earth-entering device 105 is pushed to the second position under the action of the pile driver 40, and the anchor claw 20 is driven to the second relative position of the retracted state, so that the mooring anchor can enter the soil layer. After the anchor rod 10 and the anchor claw 20 extend into the soil layer to a preset depth, the pile driver 40 is withdrawn, and the anchor chain 30 slowly applies tension to pull the auxiliary earth-entering device 105 to the first position, and the anchor claw 20 is driven to the first relative position of the open state. The anchor claw 20 is tightly fitted with the soil layer, the action force is increased, and the greater the tension applied by the surface float and the anchor chain 30, the greater the tension on the anchor claw 20, which reduces the risk of dragging the anchor and improves the reliability of mooring.

[0060] The switching of the auxiliary burying device 105 between the first position and the second position may also be controlled by the pile driver 40 or a power device on the mooring anchor, such as a cylinder, etc., which is not limited in the embodiment of the present invention.

[0061] Optionally, refer to Figures 1 to 5 As shown, the auxiliary burrowing device 105 includes a conical block 1051 and a shaft 1052; the conical block 1051 is hinged to the anchor claw 20, and along the axial direction of the anchor rod 10, the projection area of ​​the conical block 1051 on the side away from the main body 104 is smaller than the projection area of ​​the conical block 1051 on the side close to the main body 104; the shaft 1052 is penetrated through the accommodating cavity 101 and the conical block 1051, the shaft 1052 is slidably connected to the main body 104, and the conical block 1051 is fixedly connected to the shaft 1052; on the side of the conical block 1051 away from the main body 104, the shaft 1052 protrudes from the conical block 1051, and along the axial direction of the anchor rod 10, the projection area of ​​the shaft 1052 is smaller than the projection area of ​​the conical block 1051.

[0062] Specifically, if Figures 1 to 5As shown, the conical block 1051 can be surrounded by triangular steel plates, and the projection area of ​​the conical block 1051 on the side away from the main body 104 is smaller than the projection area of ​​the conical block 1051 on the side close to the main body 104, that is, the tip of the conical block 1051 is away from the main body 104 and faces the soil layer, which is convenient for the mooring anchor to enter the soil layer. In addition, the shaft rod 1052 is inserted into the accommodating cavity 101 and the conical block 1051. On the side of the conical block 1051 away from the main body 104, the shaft rod 1052 protrudes from the conical block 1051, and along the axial direction of the anchor rod 10, the projection area of ​​the shaft rod 1052 is smaller than the projection area of ​​the conical block 1051, that is, the tip of the shaft rod 1052 is also facing the soil layer, which further improves the construction efficiency.

[0063] The shaft 1052 is inserted through the accommodating cavity 101 and the tapered block 1051, the shaft 1052 is slidably connected to the main body 104, and the tapered block 1051 is fixedly connected to the shaft 1052. The pile driver 40 pushes against the shaft 1052, so that the shaft 1052 and the tapered block 1051 can be driven to move simultaneously, and the entire shaft 1052 and the tapered block 1051, that is, the auxiliary earth-entering device 105, is switched from the first position to the second position, thereby driving the anchor claw 20 to rotate to the second relative position of the retracted state, thereby improving the earth-entering efficiency of the mooring anchor.

[0064] Optionally, refer to Figures 1 to 5 As shown, a first mounting portion 106 is provided on the outer surface of the anchor rod 10 , and the fluke 20 is hinged to the first mounting portion 106 .

[0065] Specifically, if Figures 1 to 5 As shown, a first mounting portion 106 is extended from the outer surface of the anchor rod 10, and a hinge hole is opened on the first mounting portion 106. Correspondingly, a hinge hole is also provided on the fluke 20. The fluke 20 is hinged to the anchor rod 10 through the first mounting portion 106 and the rotating shaft to achieve switching between the first relative position and the second relative position. The number of the first mounting portions 106 matches the number of the flukes 20. By providing the first mounting portion 106, it is not necessary to directly open a hole on the anchor rod 10, so as to avoid affecting the structural strength of the anchor rod 10.

[0066] Optionally, refer to Figures 1 to 5 As shown, the conical block 1051 is provided with a second mounting portion 1053 , and the fluke 20 is hinged to the second mounting portion 1053 .

[0067] Specifically, if Figures 1 to 5As shown, a second mounting portion 1053 is extended on the conical block 1051, and a hinge hole is opened on the second mounting portion 1053. Correspondingly, a hinge hole is also provided on the fluke 20. The fluke 20 is hinged to the anchor rod 10 through the second mounting portion 1053 and the rotating shaft. The fluke 20 can be switched between the first relative position and the second relative position by switching the conical block 1051 and the shaft 1052 as a whole between the first position and the second position. The number of the second mounting portions 1053 matches the number of the flukes 20. By providing the second mounting portion 1053, it is not necessary to directly open a hole on the conical block 1051, so as to avoid affecting the structural strength of the conical block 1051.

[0068] Optionally, refer to Figure 5 As shown, one end of the shaft rod 1052 close to the main body 104 is connected to the anchor chain 30 .

[0069] Specifically, if Figure 5 As shown, the shaft 1052 is directly connected to the anchor chain 30. After the anchor 10 and the anchor claw 20 extend into the soil layer to a preset depth, the pile driver 40 is withdrawn, and the anchor chain 30 slowly applies tension to pull the shaft 1052 and the tapered block 1051 as a whole, that is, the auxiliary burying device 105, to the first position, and at the same time drive the anchor claw 20 to the first relative position in the open state. The anchor claw 20 fits tightly with the soil layer, the acting force increases, and the greater the tension applied by the water surface float and the anchor chain 30, the greater the tension on the anchor claw 20, thereby reducing the risk of dragging the anchor and improving the reliability of the mooring.

[0070] Optionally, refer to Figures 1 to 5 As shown, the number of flukes 20 is at least two, and the at least two flukes 20 are symmetrically distributed.

[0071] Specifically, if Figures 1 to 5 As shown, the number of the flukes 20 may be two or more, and the flukes 20 are symmetrically distributed on the outer surface of the anchor rod 10, which can ensure that each fluke 20 is evenly stressed and improve the durability of the mooring anchor.

[0072] Optionally, refer to Figure 1 As shown, the fluke 20 includes a first wing plate 201 and a second wing plate 202 distributed at an angle; from the direction close to the anchor rod 10 to the direction away from the anchor rod 10, the cross-sectional area of ​​the first wing plate 201 and / or the cross-sectional area of ​​the second wing plate 202 gradually decreases.

[0073] Specifically, if Figure 1As shown, the anchor claw 20 includes a first wing plate 201 and a second wing plate 202 that are distributed at an angle, and the angle is preferably a right angle, but can also be other angles, which can be set according to actual conditions. The combined structure of the first wing plate 201 and the second wing plate 202 can improve the structural strength of the anchor claw 20, and when the anchor claw 20 contacts the soil layer, the contact area between the anchor claw 20 and the soil layer can also be increased, thereby improving the mooring reliability.

[0074] From the direction close to the anchor rod 10 to the direction away from the anchor rod 10 , the cross-sectional area of ​​the first wing plate 201 and / or the cross-sectional area of ​​the second wing plate 202 gradually decreases, so as to facilitate the anchor claw 20 to extend into the soil layer.

[0075] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
