Description

Technical Field

[0001] The present application relates to the technical field of anchor body devices, and particularly to a rotary-wing anchor body device and a floating system. Background Art

[0002] In order to facilitate water operations, such as supporting and stabilizing ships and docks, collecting water information, setting up photovoltaic devices, etc., it is necessary to fix the floating system in a certain position. The anchoring system is a key stabilizing structure that can restrain the floating system and remain stable under the action of wind and waves to prevent collisions or capsizes.

[0003] The anchoring system mainly consists of anchor cables and underwater anchor bodies. Currently, the commonly used anchor bodies in engineering are concrete gravity anchors and screw pile anchors. The concrete gravity anchor relies on the self-weight of the concrete to fix the anchor chain. Its large volume will change the hydrodynamic environment, and a scouring area will be formed around the concrete block, resulting in changes in the seabed topography and affecting the underwater ecological environment. The bearing capacity of a single screw pile anchor is relatively low. A large number of anchors are required to fix a floating square array, and it is not suitable for deep water areas.

[0004] With the development of floating photovoltaic power stations, the number of offshore floating photovoltaic power stations is gradually increasing; compared with inland waters, the wind and wave actions faced by offshore floating photovoltaics during operation are stronger, and the anchoring system needs to provide greater uplift bearing capacity to ensure the safety of the upper photovoltaic power generation system.

[0005] Therefore, in the existing anchoring system, the bearing capacity of a single anchor is relatively low, and there is a problem that the anchoring system cannot provide sufficient uplift bearing capacity while reducing the impact on the environment, and cannot meet the anchoring requirements of floating photovoltaic devices or equipment. Summary of the Invention

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0038] With reference to Figure 1 、 Figure 2 and Figure 3 ,the present application provides a rotor-type anchor device, including: an anchor main body 2, a plurality of bottom rotors 5, and a plurality of transmission rods 3. A plurality of the transmission rods 3 penetrate through the anchor main body 2, and the plurality of transmission rods 3 are respectively connected to the plurality of bottom rotors 5 in one-to-one correspondence; the bottom rotors 5 are attached to the bottom of the anchor main body 2 through the transmission rods 3; by rotating the transmission rods 3, the corresponding bottom rotors 5 are driven to rotate so as to extend or retract the bottom rotors 5 from the bottom of the anchor main body 2.

[0039] The anchor main body 2 can be a hollow structure or a solid structure, and a channel for the transmission rod 3 to penetrate is provided inside the anchor main body 2; the hollow structure can reduce the production cost and facilitate the construction of a channel for the transmission rod 3 to penetrate inside the anchor main body 2; preferably, it is a solid structure, which is convenient for pressing the rotor-type anchor device into the soil underwater after the rotor-type anchor device is put into the water. The transmission rod 3 penetrates through and is connected to the anchor main body 2, which can improve the connection stability between the transmission rod 3 and the anchor main body 2, and also facilitate the limitation of the transmission rod 3, reducing the surface area of the rotor-type anchor device, so that when the rotor-type anchor device is pressed into the soil underwater, a smaller force can be used to press the rotor-type anchor device deeper into the soil underwater. The anchor main body 2 can be a cylinder, a cuboid, a cube, a frustum of a cone, etc., preferably a cylinder or a frustum of a cone.

[0040] The bottom rotors 5 are attached to the bottom of the anchor main body 2 through the transmission rods 3, which can facilitate the support of the bottom rotors 5 by the anchor main body 2 during the subsequent process of pressing the anchor main body 2 into the soil underwater, preventing the bottom rotors 5 from being damaged; at the same time, preventing soil or other foreign objects from being clamped between the bottom rotors 5 and the anchor main body 2, which may hinder the subsequent rotation of the bottom rotors 5.

[0041] When the rotor - type anchor device is inserted into the soil underwater, the bottom rotor 5 needs to be retracted into the bottom of the anchor body 2, so as to reduce the stress area at the bottom of the rotor - type anchor device, enabling the device to be embedded deeper underwater after being put into the water; moreover, due to the relatively small volume of the anchor body 2 itself, it can reduce the damage to the underwater environment and prevent significant changes in the underwater landform; and it is convenient to use methods such as hydrostatic pressure or negative - pressure suction to press the anchor body 2 deeper underwater when pressing the anchor body 2 into the underwater soil, thereby improving the uplift bearing capacity of the rotor - type anchor device; subsequently, the bottom rotor 5 can be unfolded, so that the bottom rotor 5 extends out of the bottom of the anchor body 2, further expanding the bottom area of the rotor - type anchor device, increasing the contact surface between the rotor - type anchor device and the underwater bottom soil layer or rock layer. The bottom rotor 5 can be inserted into relatively dense soil or hard rock, improving the uplift and compressive bearing capacities of the rotor - type anchor device. The number of bottom rotors 5 can be several, and the number of bottom rotors 5 can be increased according to actual needs, thereby providing stronger uplift and compressive bearing capacities for the rotor - type anchor device.

[0042] The rotor - type anchor device of this embodiment includes an anchor body 2, a bottom rotor 5, and a transmission rod 3. The bottom rotor 5 and the transmission rod 3 are connected to the anchor body 2 in one - to - one correspondence. During use, the bottom rotor 5 can be retracted into the bottom of the anchor body 2, and the anchor body 2 together with the bottom rotor 5 can be penetrated into the soil by means of hydrostatic pressure or negative - pressure suction, reducing the impact on the underwater environment; then, the transmission rod 3 is rotated to unfold the bottom rotor 5, expanding the bottom area of the anchor body 2, thereby increasing the connection surface between the rotor - type anchor device and the underwater substances and improving the uplift and compressive bearing capacities of the rotor - type anchor device. That is, the rotor - type anchor device of this embodiment can flexibly unfold or retract the bottom rotor 5 into the bottom of the anchor body 2 as needed, thereby improving the uplift and compressive bearing capacities of the rotor - type anchor device.

[0043] The transmission rod 3 can be a solid rod, which is convenient for force transmission, thus rotating the transmission rod 3; the transmission rod 3 can also be a hollow structure, and the cross - section of the hollow structure can be cruciform, linear, or star - shaped, etc. After the rotor - type anchor device is pressed into the underwater soil layer or rock layer, the transmission rod 3 can be rotated by sleeving a connection head corresponding to the transmission rod 3 on a hydraulic torque wrench or a drill, driving the bottom rotor 5 to rotate, and realizing the unfolding or retraction of the bottom rotor 5.

[0044] The end of the transmission rod 3 away from the bottom rotor 5 can penetrate the anchor body 2 and then pass through the top of the anchor body 2, so that the transmission rod 3 can be rotated through the passing part. The end of the transmission rod 3 away from the bottom rotor 5 can also penetrate the anchor body 2 and be connected with the anchor body 2, that is, the end away from the bottom rotor 5 is completely embedded in the anchor body 2. At this time, a groove is provided on the top of the end of the transmission rod 3 embedded in the anchor body 2, or the transmission rod 3 is a hollow structure, which is convenient for an external rotation drive such as a hydraulic torque wrench or a drilling rig to be connected to the transmission rod 3 by sleeves of a connector matching the shape of the groove, or sleeves of a connector matching the hollow structure of the transmission rod 3, and then rotate the transmission rod 3. Rotation drive such as a hydraulic torque wrench or a drilling rig can be used for underwater operations, connected to the transmission rod 3, and drive the transmission rod 3 to rotate; magnetic material can be added to the connector between the rotation drive and the transmission rod 3 and the material of the transmission rod 3, so that the two can be quickly connected, thereby driving the transmission rod 3 to rotate, and improving the efficiency of the deployment and retraction of the transmission rod 3.

[0045] The end of the transmission rod 3 away from the bottom rotor 5 is preferably set through the anchor body 2, and is preferably a solid structure to prevent the transmission rod 3 from being corroded due to being placed underwater for a long time, making it difficult to connect with the external rotating drive member, and to improve the strength of the transmission rod 3. Several bottom rotors 5 are connected to the anchor body 2 through the corresponding transmission rods 3. After the rotor anchor device is embedded deep in the underwater soil, the several transmission rods 3 can be rotated sequentially or simultaneously by an external rotating drive member such as a hydraulic torque wrench or a drilling rig, so that the several bottom rotors 5 are deployed, that is, the rotation of the bottom rotor 5 is independent and flexible. The transmission rods 3 corresponding to the several bottom rotors 5 can also be fixedly connected to each other through a connecting ring, and then the several bottom rotors 5 are directly extended from the bottom of the anchor body 2 in the direction away from the anchor body 2 by rotating the connecting ring to reach the deployed state; by rotating the connecting ring in the opposite direction, the several bottom rotors 5 are retracted into the bottom of the anchor body 2 to reach the retracted state; this can improve the efficiency of the deployment and retraction of the bottom rotors 5.

[0046] Combined with reference Figure 4 In some embodiments, the rotary anchor device further comprises a plurality of top slip rings 6, which are sleeved one by one on the outside of the plurality of transmission rods 3; a plurality of connecting through holes 9 are arranged at the top of the anchor body 2, and the plurality of top slip rings 6 are interference-connected with the plurality of connecting through holes 9 one by one, and the transmission rod 3 is interference-connected with the anchor body 2 through the top slip rings 6. The transmission rod 3 can be stably connected with the anchor body 2 through the interference connection between the top slip rings 6 and the connecting through holes 9. Specifically, the anchor body 2 comprises a top cover plate 1, and the connecting through holes 9 are all arranged on the top cover plate 1, and the number of the connecting through holes 9 corresponds one by one to the number of the transmission rods 3.

[0047] The anchor body main body 2 further includes a bottom cover plate 8. One end of the transmission rod 3 passes through the bottom cover plate 8 and is connected to the bottom rotor 5. The bottom rotor 5 is arranged in contact with the bottom cover plate 8, which is convenient for reducing the overall stress area of the rotor-type anchor device during the process of pressing the rotor-type anchor device into the water.

[0048] In some embodiments, the bottom rotor 5 includes a rotor main body 501. The rotor main body 501 is arc-shaped, and the centers of the rotor main body 501 are all located inside the bottom of the anchor body main body 2. That is, the inner edges of the rotor main body 501 all face the inside of the bottom of the anchor body main body 2, and the outer edges of the rotor main body 501 all face the outside of the bottom of the anchor body main body 2. Preferably, the rotor main body 501 of the bottom rotor 5 is arranged around the outer edge of the anchor body main body 2. The bottom rotor 5 is preferably two or more, so as to increase the area when the bottom rotor 5 unfolds and effectively improve the tensile and uplift bearing capacities of the device.

[0049] The bottom rotor 5 can be two, namely the bottom first rotor 51 and the bottom second rotor 52. They are arranged correspondingly and have a gap between them, which can prevent the collision between adjacent bottom rotors 5. The arc angles of the two bottom rotors 5 are preferably both greater than 90° and less than 180°. Thus, when the bottom rotor 5 unfolds, the area of the part extending out of the anchor body main body 2 is significantly increased, and two corresponding force application points are added, improving the tensile and uplift bearing capacities of the anchor body main body 2 and the rotor-type anchor device. At this time, the transmission rod 3, the top slip ring 6, and the bottom slip ring 4 are all two, and are respectively connected to the bottom first rotor 51 and the bottom second rotor 52 correspondingly.

[0050] The bottom rotor 5 can be three, namely the bottom first rotor 51, the bottom second rotor 52, and the bottom third rotor 53. They are arranged around and have a gap between them, which can prevent the collision between adjacent bottom rotors 5. The arc angles of the three bottom rotors 5 are preferably all greater than 90° and less than 120°. Thus, when the bottom rotor 5 unfolds, the area of the part extending out of the anchor body main body 2 is significantly increased, and three corresponding force application points are added. The three-point force application points have stronger stability, improving the tensile and uplift bearing capacities of the anchor body main body 2 and the rotor-type anchor device. At this time, the transmission rod 3, the top slip ring 6, and the bottom slip ring 4 are all three, and are respectively connected to the bottom first rotor 51, the bottom second rotor 52, and the bottom third rotor 53 correspondingly.

[0051] There may be four bottom rotors 5, namely a first bottom rotor 51, a second bottom rotor 52, a third bottom rotor 53 and a fourth bottom rotor 54. The four are arranged in a surrounding manner with gaps between every two of them, which can prevent collisions between adjacent bottom rotors 5. The arc angles of the four bottom rotors 5 are preferably less than 90° and greater than 60°. Thus, when the bottom rotors 5 are deployed, the area of the part extending out of the anchor body main body 2 is significantly increased, and four corresponding force points are added. The four force points can better share the pressure, improve the stability of the structure while extending the service life of the structure, and improve the tensile and uplift bearing capacities of the anchor body main body 2 and the rotor-type anchor device.

[0052] Correspondingly, there are also four top slip rings 6. The top slip rings 6 include a first top slip ring 61, a second top slip ring 62, a third top slip ring 63 and a fourth top slip ring 64. At the same time, there are also four transmission rods 3. Among them, one end of a transmission rod 3 is connected to the anchor body main body 2 through the first top slip ring 61, and the other end is connected to the first bottom rotor 51; one end of a transmission rod 3 is connected to the anchor body main body 2 through the second top slip ring 62, and the other end is connected to the second bottom rotor 52; one end of a transmission rod 3 is connected to the anchor body main body 2 through the third top slip ring 63, and the other end is connected to the third bottom rotor 53; one end of a transmission rod 3 is connected to the anchor body main body 2 through the fourth top slip ring 64, and the other end is connected to the fourth bottom rotor 54.

[0053] In some embodiments, the centers of the several rotor main bodies 501 overlap at the same point. By overlapping the centers of the rotor main bodies 501 at the same point, the arcs of the rotor main bodies 501 can be made consistent, which is convenient for processing and manufacturing. After the anchor body main body 2 is pressed into the soil underwater, several transmission rods 3 can be rotated in the same direction to make several rotor main bodies 501 expand in the direction away from the anchor body main body 2 and extend out of the bottom of the anchor body main body 2. Subsequently, several transmission rods 3 can be rotated in the opposite direction to retract several rotor main bodies 501 into the bottom of the anchor body main body 2.

[0054] The bottom of the transmission rod 3 and the bottom rotor 5 can be integrally formed. After passing through the anchor body main body 2 from the end away from the bottom rotor 5, it is then in interference connection with the connection through hole 9 through the top slip ring 6. Alternatively, the rotor-type anchor device further includes several bottom slip rings 4, and several of the bottom slip rings 4 are sleeved on the outer sides of several of the transmission rods 3 one by one. Several connection holes 503 are provided on the rotor main body 501, and several of the connection holes 503 are in interference connection with several of the bottom slip rings 4 one by one. The transmission rod 3 is in interference connection with the rotor main body 501 through the bottom slip ring 4. That is, the connection stability between the transmission rod 3 and the rotor main body 501 can be improved through the bottom slip ring 4.

[0055] Meanwhile, through holes corresponding to the bottom slip ring 4 can also be provided on the bottom top cover, and can be in interference connection with the bottom slip ring 4, that is, the through holes on the bottom cover plate 8 can be in interference connection with the bottom slip ring 4, and the connection through holes 9 on the top cover plate 1 can be in interference connection with the top slip ring 6, so as to ensure the sealing performance of the channel provided on the anchor body main body 2 for the transmission rod 3 to pass through, prevent water, foreign objects, etc. from entering the channel, prevent the rusted connection between the transmission rod 3 and the anchor body main body 2, reduce the rotation difficulty of the transmission rod 3, and extend the service life of the device.

[0056] With reference to Figure 5 and Figure 6 , in some embodiments, a first protrusion 601 is provided on the top slip ring 6, and a corresponding first groove 31 is provided on the transmission rod 3; alternatively, a third groove 603 is provided on the top slip ring 6, and a corresponding third protrusion 33 is provided on the transmission rod 3.

[0057] Through the snap connection of the first protrusion 601 and the first groove 31, or the third protrusion 33 and the third groove 603, the connection stability between the top slip ring 6 and the transmission rod 3 is enhanced. After connecting the top slip ring 6 and the transmission rod 3, the top slip ring 6 is pressed into the connection through hole 9, so that the top slip ring 6 is in interference connection with the connection through hole 9, thereby improving the connection stability between the transmission rod 3 and the anchor body main body 2; it can ensure that during the process of pressing the rotary-wing anchor device into the soil underwater, the transmission rod 3 is tightly connected to the anchor body main body 2, and the bottom rotary wing 5 is tightly attached to the bottom of the anchor body main body 2, thereby reducing the bottom surface area of the anchor body main body 2 and facilitating the pressing of the rotary-wing anchor device deeper.

[0058] The top slip ring 6 is preferably an elastic member, so that both the first protrusion 601 and the first groove 31, or the third protrusion 33 and the third groove 603 can be in interference fit connection. Similarly, the bottom slip ring 4 is also preferably an elastic member, which is convenient for the bottom slip ring 4 to be in interference connection with the connection hole 503 and the through holes on the bottom cover plate 8.

[0059] A second protrusion 602 can also be provided on the top slip ring 6, and a corresponding second groove 32 is provided on the transmission rod 3; the second groove 32 and the second protrusion 602 cooperate with the first groove 31 and the first protrusion 601 to further improve the connection stability between the top slip ring 6 and the transmission rod 3; both the first protrusion 601 and the second protrusion 602 are preferably provided in the middle of the top slip ring 6. Alternatively, a fourth groove 604 can also be provided on the top slip ring 6, and a corresponding fourth protrusion 34 is provided on the transmission rod 3; the fourth groove 604 and the fourth protrusion 34 cooperate with the third groove 603 and the third protrusion 33 to further improve the connection stability between the top slip ring 6 and the transmission rod 3. The third groove 603 and the fourth groove 604 are provided at the upper end or the lower end of the top slip ring 6, which is convenient for the transmission rod 3 to be directly inserted into the top slip ring 6 from top to bottom or from bottom to top.

[0060] Combined reference Figure 7 In some embodiments, threads are provided on the outer side of the transmission rod 3; alternatively, a fitting portion 701 is provided at the top of the transmission rod 3, facilitating the connection of the transmission rod 3 to an external hydraulic torque wrench or drill rig, increasing the contact area and roughness of the connection, improving the connection stability, thereby facilitating the transmission of force and facilitating the rotation of the transmission rod 3. When rotating the transmission rod 3, providing sufficient force can ensure the stable connection between the top slip ring 6 and the top cover plate 1, fix the position of the transmission rod 3, while rotating the transmission rod 3, preventing water and the like from entering the connection channel between the anchor body 2 and the transmission rod 3 through the top slip ring 6 and the bottom slip ring 4, and extending the service life of the device.

[0061] Specifically, a connector 7 can be provided at the top of the transmission rod 3, and the transmission rod 3 is connected to an external hydraulic torque wrench or drill rig through the connector 7; threads or a fitting portion 701 can be provided on the outer side of the connector 7, that is, it can be fitted and connected to the inner or outer side of the external hydraulic torque wrench or drill rig through the threads or the fitting portion 701, thereby rotating the transmission rod 3.

[0062] A waterproof ring can be provided on the outer side of the connection between the top slip ring 6 and the anchor body 2, and on the outer side of the connection between the bottom slip ring 4 and the anchor body 2, which can prevent water from surging into the connection channel between the anchor body 2 and the transmission rod 3, prevent the transmission rod 3 from rusting, and thus be completely fixedly connected to the anchor body 2 and be difficult to rotate.

[0063] In some embodiments, the thickness of the rotor main body 501 decreases along the direction away from the center of the anchor body 2. That is, the outer edge of the rotor main body 501 is sharper than the inner edge, facilitating the inner edge of the rotor to come into contact with the soil layer first when pressing the device into the soil underwater, thereby facilitating the device to be pressed deeper underwater; and the outer edge of the rotor main body 501 is relatively sharp. When the transmission rod 3 drives the rotor main body 501 to rotate, the outer edge of the rotor main body 501 will insert into the hard soil layer or rock formation for fixation, further improving the tensile and uplift bearing capacities of the device.

[0064] Combined reference Figure 8 and Figure 9 In some embodiments, the bottom rotor 5 further includes a blade portion 502, and the blade portion 502 is provided on the side of the rotor main body 501 away from the anchor body 2. The blade portion 502 breaks through the soft layer and inserts into the hard soil layer or rock formation for fixation, further improving the tensile and uplift bearing capacities of the device.

[0065] Specifically, one side of the blade 502 is level with the rotor body 501, so as to fit closely with the bottom cover plate 8, and the other side is sharpened, that is, the thickness of the side of the blade 502 away from the bottom cover plate 8 decreases in the direction away from the rotor body 501, so as to facilitate breaking the soft soil or mud layer under water and inserting into the hard soil or rock layer for fixing. Alternatively, both sides of the blade 502 are sharpened, that is, the thickness of both sides of the blade 502 decreases in the direction away from the rotor body 501, so as to increase the sharpness of the blade 502 and increase the sharpness of the blade 502.

[0066] Specifically, the outer sides of the anchor body 2, the transmission rod 3 and the bottom rotor 5 are coated with anti-rust paint, anti-rust coating, anti-corrosion coating, etc., so as to ensure that their structural shapes remain unchanged and their functions can be operated normally.

[0067] The second embodiment of the present application provides a floating system, including a floating body, a cable chain and a rotary anchor device, wherein the floating body is connected to the rotary anchor device through the cable chain, and the rotary anchor device is the rotary anchor device as described in the first embodiment or its implementation manner.

[0068] The floating body can be a buoy, a floating photovoltaic power station, etc., which is connected to the anchor body 2 of the rotary anchor device through a cable chain. After the connected anchor body 2 is pressed into the underwater soil, the position of the floating body is fixed by the anchor body 2, and a pulling force is provided for the floating body; when the wind and waves push the floating body, the floating body is pulled to prevent the floating body from turning over. The rotary anchor device can provide greater pulling force for the floating body through a plurality of rotary bodies 501 and the arrangement of inserting the anchor body 2 deeper into the underwater soil, and can be applied to different environments such as sea, river, and lake.

[0069] Therefore, the floating system of this embodiment is connected to the cable chain through a rotor-type anchor device, which provides sufficient pulling force for the floating body, enabling it to be used in different environments such as sea, river, and lake, thereby expanding the scope of application. At the same time, the overall volume of the rotor-type anchor device is relatively small, which can reduce the impact on the environment during its application, prevent changes in the bottom morphology, and has better safety and environmental protection.

[0070] In summary, the present application provides a rotor-type anchor device and a floating system, including an anchor body, a bottom rotor and a transmission rod, wherein the bottom rotor and the transmission rod are connected to the anchor body one by one. When in use, the bottom rotor can be retracted into the bottom of the anchor body, and the anchor body connected to the bottom rotor can be pressed deep into the underwater soil by static pressure or negative pressure suction, thereby reducing the impact on the underwater environment; and then the transmission rod is rotated to unfold the bottom rotor to expand the bottom area of ​​the anchor body, thereby increasing the connection surface between the rotor-type anchor device and the bottom material, improving the pull-out and compressive bearing capacity of the rotor-type anchor device, and meeting the anchoring needs of floating photovoltaic devices or equipment.
