Description

Technical Field

[0001] This utility model belongs to the field of anchoring equipment, and in particular relates to a universal anchor. Background Technology

[0002] An anchor is the main component for temporarily or permanently securing floating objects at sea. Its form, weight, and safety factor directly determine the mooring safety of the floating object. In current technology, deep-sea floating objects or marine aquaculture equipment are generally moored using single-point anchoring to reduce mooring costs. However, traditional anchors can only generate tension in specific directions and angles. Therefore, when the direction of surface water flow or wind changes, the anchor often drags, which seriously affects the mooring effect.

[0003] To address the aforementioned issues, those skilled in the art typically employ suction anchors or anchor piles for single-point mooring. However, suction anchors are expensive to manufacture and install, making it difficult to control economic costs. Anchor piles are also challenging to install in deeper waters and cannot be maintained or reused, thus failing to meet practical application requirements. Utility Model Content

[0007] When the anchoring section rotates away from the central anchor body, the limiting section enters the cavity along the connecting cut and abuts against the hammering assembly to limit the rotation angle of the anchor blade; when the unlocking assembly is triggered, the locking cap disengages from the unlocking assembly to release the position locking of the hammering assembly and the rotation angle limitation of the anchor blade.

[0008] Furthermore, the unlocking component includes a receiving shell, the receiving shell having a filling groove on its end face away from the central anchor body, and gunpowder being filled inside the filling groove; the locking cap having a sealing plug on its end face near the receiving shell, and the sealing plug being inserted into the filling groove.

[0009] Furthermore, the outer wall of the central anchor body is provided with a mounting hole for accommodating the unlocking component, and the mounting hole is located on the side of the assembly cut away from the connection cut.

[0010] Furthermore, the two ends of the connecting plate are respectively provided with splicing groove and receiving groove; the side wall of the locking cap is provided with a positioning ring groove for receiving the splicing groove, and the end of the connecting pin is placed inside the receiving groove.

[0011] Furthermore, the connecting section has a hinge shaft on its side wall, a hinge lug on the outer wall of the central anchor body, and a hinge hole for accommodating the hinge shaft on the hinge lug.

[0012] Furthermore, the hammering assembly includes: a cylinder, a piston, and an impact spring; the cylinder has a hydraulic chamber inside, an oil guide pipe inside the hydraulic chamber, and a channel hole at the bottom of the cylinder connecting to the hydraulic chamber; a first connecting pipe and a second connecting pipe are provided at the top of the cylinder, the first connecting pipe being connected to the oil guide pipe, and the second connecting pipe being connected to the hydraulic chamber; the piston and the impact spring are both disposed inside the hydraulic chamber, with the impact spring located above the piston; a first oil guide hole is provided at the top of the piston, and a second oil guide hole is provided at the bottom of the piston, communicating with the first oil guide hole, with the bottom end of the oil guide pipe inserted into the first oil guide hole; a hammering rod is also provided on the bottom surface of the piston, and the hammering rod extends outward from the cylinder along the channel hole.

[0013] Furthermore, the top of the central anchor rod is provided with an operating hole, and the bottom end of the operating hole is connected to the receiving cavity.

[0014] Furthermore, the hammer rod has an oil guiding cavity inside, which is connected to the first oil guiding hole, and a third oil guiding hole connected to the oil guiding cavity is provided on the side wall of the hammer rod.

In use, the unfolded anchor blades provide the device with significant vertical pull-out resistance and effectively counteract horizontal tension in various directions, preventing anchor drag and improving the mooring effect of floating objects. Secondly, the device can lock the hammering assembly in position via a locking unit and limit the rotation angle of the anchor blades via the hammering assembly, thereby controlling the opening angle of the anchor blades and ensuring good anchoring effect and ease of construction. When anchor removal is required, the device can quickly release the position lock of the hammering assembly and the rotation angle restriction of the anchor blades by disengaging the locking cap from the unlocking assembly, allowing the anchor blades to continue rotating downwards in the unfolded state, thus reducing the difficulty of anchor removal. Furthermore, the device can be reused after retrieval by replacing the unlocking assembly, locking cap, and connecting plate, thereby reducing the cost of single-point mooring of floating objects.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] A universal anchor, the structure of which can be made of Figures 1-9 For illustrative purposes, in this embodiment, the universal anchor includes: a central anchor body 1, a locking unit, and multiple anchor blades. The central anchor body 1 provides an installation base for other components in the device. An accommodating cavity is provided inside the central anchor body 1, and a hammering assembly for anchoring the device into the seabed is located within the cavity. Multiple anchor blades are arranged radially around the central anchor body 1 to improve the vertical pull-out resistance of the device and enable it to withstand tension in various horizontal directions, thus improving the anchoring effect. The locking unit is used to lock the position of the hammering assembly, thereby limiting the rotation angle of the anchor blades. It also releases the position locking of the hammering assembly and the rotation angle limitation of the anchor blades when anchor removal is required, thus reducing the difficulty of construction and improving the ease of use for workers.

[0036] Specifically, in this embodiment, each anchor leaf includes an anchoring section 21, a connecting section 22, and a limiting section 23 connected in sequence. A connecting cutout 11 for accommodating the limiting section 23 is provided on the side wall of the central anchor body 1, and the connecting cutout 11 communicates with the accommodating cavity. During assembly, the connecting section 22 should be hinged to the central anchor body 1 so that the anchor leaf can rotate about the hinge point as an axis, thereby enabling the device to achieve the following... Figure 1 , Figure 2 and Figure 3 The three different working states are shown.

[0037] Figure 1 This diagram illustrates the device in its drilling state. In this state, the hammering assembly can be used to drive the device into the seabed. Once the device is driven into the seabed, workers can pull it up using the anchor chain (not shown). Due to the obstruction of sediment, the anchoring section 21 will rotate away from the central anchor body 1, allowing the limiting section 23 to enter the receiving cavity along the connecting cut 11 and abut against the hammering assembly, ultimately forming... Figure 2 The anchoring state is shown. In this state, the abutting relationship between the limiting section 23 and the hammering assembly restricts the rotation angle of the anchor blade, thus ensuring that the opening of the anchor blade meets the anchoring requirements of the floating object, thereby producing a good mooring effect. When anchor removal is required, the operator can first release the position locking of the hammering assembly and the rotation angle restriction of the anchor blade by the action of the locking unit, and then pull the device up via the anchor chain. During this process, the anchor blade will continue to rotate under the obstruction of silt, thus forming a state as shown. Figure 3 The anchoring position shown is to facilitate the removal of this device from the seabed and its reuse after recovery.

[0038] Optionally, to achieve the hinge connection between the connecting section 22 and the central anchor body 1, a hinge shaft 221 may be provided on the side wall of the connecting section 22. Correspondingly, a hinge lug 14 should be provided on the outer wall of the central anchor body 1, and a hinge hole 141 for accommodating the hinge shaft 221 should be provided on the hinge lug 14, so that the anchor blade can rotate smoothly during use by means of the cooperation between the hinge shaft 221 and the hinge lug 14.

[0039] As an optional implementation of this embodiment, to facilitate the insertion of the device into the seabed, a piercing cone 6 may be provided at the bottom end of the central anchor body 1 to reduce the difficulty of inserting the central anchor body 1 into the seabed. Simultaneously, a counterweight core 61 made of metallic lead or other high-density materials may be provided inside the piercing cone 6, thereby concentrating the center of gravity of the device at the bottom end of the central anchor body 1, facilitating the device's descent perpendicular to the seabed after being deployed into the water. Furthermore, a connecting plate 5 rotatably connected to the central anchor body 1 may be provided at the top of the device to facilitate the connection between the anchor chain and the device.

[0040] Figure 6 This is a structural diagram of the locking unit and the hammering assembly. Figure 7 The exploded view of the locking unit is shown in the figure. In this embodiment, the locking unit includes an unlocking component, a locking cap 32, a connecting plate 33, and a connecting pin 34. The unlocking component is detachably mounted on the central anchor body 1. The locking cap 32 is located at the end of the unlocking component away from the central anchor body 1, and the connecting pin 34 is connected to the hammering component. An assembly cutout 12 is provided on the side wall of the accommodating cavity along the length of the central anchor body 1. The end of the connecting pin 34 extends outward from the central anchor body 1 along the assembly cutout 12. The connecting plate 33 is located outside the central anchor body 1, and both ends of the connecting plate 33 are respectively engaged with the locking cap 32 and the connecting pin 34.

[0041] Since the two ends of the connecting plate 33 are respectively engaged with the locking cap 32 and the connecting pin 34, the presence of the connecting plate 33 keeps the relative distance between the connecting pin 34 and the locking cap 32 constant. Therefore, the hammering assembly connected to the connecting pin 34 will be fixed inside the receiving cavity, thereby achieving the purpose of locking the position of the hammering assembly. Correspondingly, when the limiting section 23 of the anchor blade abuts against the hammering assembly, the anchor blade will also be unable to continue rotating, thus achieving the purpose of limiting the rotation angle of the anchor blade.

[0042] When anchor removal is required, the operator can trigger the unlocking component, causing the locking cap 32 to disengage from it. After the locking cap 32 disengages, the connecting plate 33 will also detach, allowing the connecting pin 34 to slide along the assembly notch 12, thus releasing the position lock of the hammer assembly. Consequently, the anchor blade can continue to rotate during the anchor removal process, facilitating the device's disengagement from the seabed sediment and completing the anchor removal operation.

[0043] By way of example and not limitation, the unlocking component in this embodiment may include a housing 31. For example... Figure 7 As shown, the end face of the receiving shell 31 away from the central anchor body 1 is provided with a filling groove 311, which is filled with gunpowder. The locking cap 32 is provided with a sealing plug 321 on its end face near the receiving shell 31. During assembly, the operator can insert the sealing plug 321 into the filling groove 311 to assemble the locking cap 32 with the receiving shell 31. When it is necessary to detach the locking cap 32 from the unlocking component, the operator can detonate the gunpowder, and the impact force generated by the explosion will detach the locking cap 32. Correspondingly, after the device completes the anchor removal operation and is retrieved, the operator can replace the receiving shell 31, locking cap 32, and connecting plate 33, and refill the gunpowder to make the device reusable, thus achieving low operating costs.

[0044] It should be noted that, to achieve remote detonation of the gunpowder, this device may be equipped with a hydrophone 71 and a gunpowder control box 72 electrically connected to the hydrophone 71 on the central anchor body 1. A detonator associated with the gunpowder control box 72 should also be placed inside the gunpowder. In use, the hydrophone 71 receives a specific frequency acoustic signal from the water and converts it into an electrical signal, which is then input into the gunpowder control box 72. Upon receiving the signal, the gunpowder control box 72 triggers the detonator to detonate the gunpowder. Since the specific working principles and internal structures of the hydrophone 71 and the gunpowder control box 72 are well-known, they will not be described in detail in this application.

[0045] Optionally, to facilitate the installation of the unlocking component, this embodiment may provide a mounting hole 13 on the outer wall of the central anchor body 1 for accommodating the unlocking component, and the mounting hole 13 should be located on the side of the assembly cutout 12 away from the connecting cutout 11. When the limiting segment 23 abuts against the hammering component, the anchor blade will drive the hammering component to move away from the connecting cutout 11. At this time, setting the mounting hole 13 on the side of the assembly cutout 12 away from the connecting cutout 11 can balance the force on the hammering component through the connecting plate 33, thereby improving the position locking effect of the hammering component.

[0046] In actual operation, staff can also choose to install connecting plates 33 of different lengths between locking caps 32 and connecting pins 34 according to actual needs, so that the hammering assembly can be locked at different positions, thereby adjusting the opening angle of the anchor leaf.

[0047] To ensure that the connecting plate 33 detaches along with the locking cap 32, this embodiment provides a splicing groove 331 and a receiving groove 332 at both ends of the connecting plate 33, and a positioning ring groove 322 for receiving the splicing groove 331 is provided on the side wall of the locking cap 32. During assembly, the splicing groove 331 should be inserted into the positioning ring groove 322, and the end of the connecting pin 34 should be placed inside the receiving groove 332. When the locking cap 32 is disengaged due to the triggering of the unlocking component, the presence of the positioning ring groove 322 can drive the connecting plate 33 to disengage from the connecting pin 34, so as to avoid the connecting plate 33 affecting the subsequent movement of the connecting pin 34.

[0048] Figure 9 The figure shows a cross-sectional view of the hammering assembly. In this embodiment, the hammering assembly may include a cylinder 41, a piston 42, and an impact spring 43. The cylinder 41 has a hydraulic chamber inside, with an oil guide pipe 44 inside. A channel hole connecting the hydraulic chamber is located at the bottom of the cylinder. A first connecting pipe 411 connected to the oil guide pipe 44 and a second connecting pipe 412 connected to the hydraulic chamber are located at the top of the cylinder 41. The piston 42 and the impact spring 43 are both located inside the hydraulic chamber, with the impact spring 43 positioned above the piston 42. A first oil guide hole is located at the top of the piston 42, and a second oil guide hole 421 connected to the first oil guide hole is located at the bottom of the piston 42. A hammering rod 45 is also located on the bottom surface of the piston 42. During assembly, the bottom end of the oil guide pipe 44 should be inserted into the first oil guide hole, and the hammering rod 45 should extend outward from the cylinder 41 along the channel hole. When in use, the piston 42 will move up and down reciprocally, thereby impacting the bottom surface of the cavity with the help of the hammer rod 45, so that the central anchor 1 can be driven into the seabed.

[0049] Specifically, when the piston 42 needs to move upward, hydraulic medium (e.g., hydraulic oil) enters the hammer assembly along the first connecting pipe 411 and flows downward to the piston 42 through the oil guide pipe 44, the first oil guide hole, and the second oil guide hole 421, thereby lifting the piston 42 and compressing the impact spring 43. At this time, the hydraulic medium inside the hydraulic chamber will leave the hammer assembly along the second connecting pipe 412. When the piston 42 needs to move downward, hydraulic medium enters the hydraulic chamber along the second connecting pipe 412 and, in conjunction with the elastic force inside the impact spring 43, drives the piston 42 to move. At this time, the hydraulic medium below the piston 42 will leave the hammer assembly sequentially through the second oil guide hole 421, the first oil guide, the oil guide pipe 44, and the first connecting pipe 411.

[0050] Optionally, the device may also include an oil guide cavity 451 inside the hammer rod 45 that communicates with the first oil guide hole, and a third oil guide hole 452 on the side wall of the hammer rod 45 that communicates with the oil guide cavity 451. When the piston 42 moves downward, the third oil guide hole 452 can accelerate the discharge speed of the hydraulic medium, thereby enabling the piston 42 to generate sufficient kinetic energy and ensuring that the hammering assembly outputs sufficient hammering force to the central anchor body 1.

[0051] As another optional implementation of this embodiment, to achieve the supply of hydraulic medium to the hammering assembly, the top of the central anchor bolt may be provided with an operating hole 15, and the bottom end of the operating hole 15 should be connected to the receiving cavity. In use, the pipeline for conveying the hydraulic medium can extend into the receiving cavity along the operating hole 15 and be connected to the hammering assembly via a common quick-connect coupling. After the device is anchored, the operator can loosen the quick-connect coupling by pulling a rope, thereby retrieving the pipeline.

[0052] The effects of the above solution are explained below:

[0053] This embodiment provides a universal anchor that enhances vertical pull-out resistance through multiple anchor blades and effectively counteracts horizontal tension in various directions, thereby improving the mooring effect of floating objects. Secondly, the device can lock the position of the hammering assembly through a locking unit and limit the rotation angle of the anchor blades through the hammering assembly, thus controlling the opening angle of the anchor blades and ensuring a good anchoring effect. Furthermore, the device can quickly release the position lock of the hammering assembly and the rotation angle restriction of the anchor blades through an unlocking component, thereby reducing the difficulty of anchor removal.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
