Description

Technical Field

[0001] This utility model relates to the field of marine protection equipment technology, and in particular to a device for preventing marine organism attachment for pile foundations. Background Technology

[0002] Marine biofouling refers to the phenomenon where fouling organisms, including animals, plants, and microorganisms, can attach to or inhabit underwater solid surfaces, such as pile legs, bracing, and tie rods, and adversely affect human economic activities.

[0003] Currently, physical anti-fouling devices are commonly used to reduce marine biofouling. These devices are powered by ocean dynamics, utilizing the rise and fall of tides, the undulation of swells, and changes in current direction to drive the device up and down, reciprocating on the legs, bracing, or tie rods. This mechanically removes or prevents marine organisms from attaching. Commonly used physical anti-fouling devices are rigid impact structures arranged in a ring on the legs, bracing, or tie rods. However, the efficiency of rigid impact alone is limited, and some marine organisms still adhere, affecting the cleanliness of the legs, bracing, or tie rods and compromising safety.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] like Figures 1 to 5 As shown, an anti-marine organism attachment device for pile foundations according to this embodiment includes a connecting rope 1, a collision roller 2, and a tensioning member 3. The connecting rope 1 is arranged in a loop around the outer periphery of the pile foundation. Multiple collision rollers 2 are movably arranged on the connecting rope 1 along its own length direction. A first through hole 21 is provided through the collision roller 2 along its own axis direction. The connecting rope 1 is arranged through the first through hole 21. Multiple loop-shaped tensioning members 3 are movably connected to each collision roller 2. The tensioning members 3 are connected end to end after passing through the first through hole 21, and some tensioning members 3 are located on the outer side of the outer peripheral wall of the collision roller 2.

[0032] Understandably, by setting collision rollers 2 on the connecting rope 1, the collision rollers 2 can continuously collide with the offshore support foundation under the impetus of ocean currents or marine organisms, loosening or knocking off marine organisms attached to the outer periphery of the pile foundation, reducing the chance of marine organisms attaching and becoming fixed. At the same time, the ring-shaped pulling parts 3 on the collision rollers 2 can hook and pull the marine organisms attached to the outer periphery of the pile foundation, causing the marine organisms to fall off the pile foundation, further reducing the attachment of marine organisms more comprehensively, maintaining the cleanliness of the pile foundation, effectively improving the efficiency of removing marine organisms from the outer periphery of the pile foundation, and ensuring the safety and durability of the pile foundation.

[0033] Furthermore, the pulling component 3 includes a pull rope 31 and a first quick-release head 32. The pull rope 31 has a first end 311 and a second end 312 arranged opposite to each other. The first quick-release head 32 includes a first male connector 321 and a first female connector 322. The first end 311 is connected to the first male connector 321, and the second end 312 is connected to the first female connector 322. The first male connector 321 and the first female connector 322 are detachably connected. The pull rope 31 can be made of a flexible rope, which can adapt to changes driven by ocean currents, so that the pull rope 31 can hook attached marine life in multiple directions and angles. The first quick-release head 32 makes the first male connector 321 and the first female connector 322 connected at both ends of the pull rope 31 detachable, enabling quick connection and disassembly of the pulling component 3. This facilitates the installation, maintenance, and replacement of the pulling component 3, effectively reducing the time and cost of installation, disassembly, and maintenance. Of course, the pull rope 31 can also adopt a structure with a certain degree of rigidity, such as ultra-high molecular weight polyethylene fiber thread, which can ensure the structural stability of the pull rope 31.

[0034] Specifically, the first female connector 322 has a first mounting groove 3221 on the side facing the first male connector 321. The outer peripheral wall of the first female connector 322 has a slot 3222 communicating with the first mounting groove 3221. The outer peripheral wall of the first male connector 321 has a latch 3211. The latch 3211 is inclined from the end away from the first end 311 toward the end closer to the first end 311 and away from the central axis of the first male connector 321. During installation, the first male connector 321 is simply inserted into the first mounting groove 3221, and the latch 3211 and the slot 3222 engage with each other to form a locking structure, effectively preventing the connecting parts from loosening during use, making the connection convenient and stable. During disassembly, the free end of the latch 3211 is simply pressed to compress it from the slot 3222 into the first mounting groove 3221, and the first male connector 321 can be pulled out. The workpiece can be easily disassembled and replaced without the need for cumbersome tools or time-consuming steps, significantly improving the efficiency of disassembly and assembly of the pull-out component 3.

[0035] Furthermore, multiple limiting grooves 22 are formed on the wall of the first through hole 21. All limiting grooves 22 are evenly distributed around the central axis of the first through hole 21. The limiting grooves 22 extend along the length of the collision roller 2 and pass through both ends of the collision roller 2 along its own length. A stop portion is protruding from the groove wall of the limiting groove 22 and is set adjacent to the groove opening of the limiting groove 22. The pull rope 31 is set between the stop portion and the bottom of the limiting groove 22. The setting of multiple limiting grooves 22 can effectively separate the connecting ropes 1 on the collision roller 2, preventing multiple connecting ropes 1 from piling up under the action of water flow, and ensuring a more comprehensive pulling effect on marine life from multiple directions by the pulling member 3. The setting of the stop portion can effectively ensure the connection stability of the pull rope 31 in the limiting groove 22 and prevent the pull rope 31 from coming out of the groove opening of the limiting groove 22.

[0036] Preferably, the length of the pull rope 31 is L1, and the length of the collision roller 2 is L2, where 2.5L2≤L1≤3.5L2. For example, L1 can be 2.5L2, 2.6L2, 2.7L2, 2.8L2, 2.9L2, 3.0L2, 3.1L2, 3.2L2, 3.3L2, 3.4L2, 3.5L2, etc. If the pull rope 31 is too long, it can easily lead to entanglement between multiple pull ropes 31 or between the pull rope 31 and other structural components, affecting the normal use of the anti-marine organism attachment device used for pile foundations. If the pull rope 31 is too short, it is difficult to hook marine organisms attached to the outer periphery of the pile foundation. This moderately long pull rope 31 ensures that it maintains appropriate tension within the length range of the collision roller 2, optimizing the movement range of the collision roller 2 and improving the working efficiency and stability of the pull rope 31.

[0037] In some embodiments, the anti-marine biofouling device for pile foundations further includes a separator 4, which is movably mounted on the connecting rope 1 and located between two adjacent impact rollers 2. Both the separator 4 and the impact rollers 2 are floating components, either floating between the sea surface and the seabed or floating on the sea surface. The separator 4 creates a small gap between adjacent impact rollers 2, allowing the sharp edges of the impact rollers 2 to impact marine organisms attached to the pile foundation. Depending on the cleaning needs and the density of the local seawater environment, a material of the required density is selected to ensure that the impact rollers 2 and the separator 4 can float on the sea surface or between the sea surface and the seabed, thereby enabling floating impact against the pile foundation supported on the seabed. It is worth noting that the outer diameter of the separator 4 should be smaller than the outer diameter of the impact rollers 2 to create a collision structure with varying heights between the impact rollers 2 and the separator 4, ensuring the impact effectiveness of the anti-marine biofouling device for the pile foundation.

[0038] Optionally, the separator 4 has a second through hole 41 extending along its length. The connecting rope 1 passes through the second through hole 41. A tension member 3 is also provided on the separator 4. The tension member 3 passes through the second through hole 41 and is connected end-to-end, with part of the tension member 3 located on the outer side of the outer peripheral wall of the separator 4. By providing tension members 3 on the separator 4, the cleaning ability of the anti-marine organism attachment device used for pile foundations against attached marine organisms can be further improved. Furthermore, in this embodiment, multiple separators 4 are provided between two adjacent collision rollers 2 to ensure the spacing between them. The multiple separators 4 between two adjacent collision rollers 2 form a group. The tension member 3 passes through multiple separators 4 within the same group, which can enhance the connection stability between the multiple separators 4 within the same group.

[0039] Furthermore, the anti-marine organism attachment device for pile foundations also includes a second quick-release head 5. The connecting rope 1 has a third end 11 and a fourth end 12 arranged opposite to each other. The second quick-release head 5 includes a second male connector 51 and a second female connector 52. The third end 11 and the second male connector 51 are rotatably connected, and the fourth end 12 is connected to the second female connector 52. The outer peripheral wall of the second male connector 51 is provided with a first thread, and the second female connector 52 has a second threaded hole 521 on the side facing the second male connector 51. The first thread engages with the thread of the second threaded hole 521, and the second male connector 51 is screwed into the second threaded hole 521. The second quick-release head 5 allows the second male connector 51 and the second female connector 52 connected at both ends of the connecting rope 1 to be detachable, enabling rapid connection and disassembly of the anti-marine organism attachment device for pile foundations. This facilitates the installation, maintenance, and replacement of the device, resulting in high construction efficiency and effectively reducing the time and cost of installation, disassembly, and maintenance. The threaded connection is stable and convenient.

[0040] Preferably, the second quick-release head 5 further includes a bolt 53, and the outer peripheral wall of the second female connector 52 has a third threaded hole 522 communicating with the second threaded hole 521. The bolt 53 passes through the third threaded hole 522 and abuts against the second male connector 51. By using the bolt 53 to tighten the second male connector 51, the connection stability between the second male connector 51 and the second female connector 52 can be further enhanced, reducing the occurrence of the second male connector 51 loosening.

[0041] Of course, other methods can also be used for secondary reinforcement of the second male connector 51 connection. The second quick-release head 5 also includes an anaerobic adhesive layer and a sealing plug 54. The second threaded hole 521 is coated with an anaerobic adhesive layer, and the sealing plug 54 is used to seal the opening of the second threaded hole 521. In the initial state, the sealing plug 54 seals the opening of the second threaded hole 521 to prevent the anaerobic adhesive layer from contacting external oxygen. During connection, the sealing plug 54 is removed, and the second male connector 51 is screwed into the second threaded hole 521 for connection. At the same time, the anaerobic adhesive layer connects to the hole walls of the second male connector 51 and the second threaded hole 521, and cures upon contact with oxygen, further enhancing the connection stability between the second male connector 51 and the second female connector 52.

[0042] Alternatively, the second quick-release head 5 may also include a sleeve 55, which is fitted over the second male connector 51 and the second female connector 52. The sleeve 55 has a third thread inside, and the outer peripheral walls of the second male connector 51 and the second female connector 52 are respectively provided with fourth threads, with the third thread engaging with the fourth thread. The sleeve simultaneously connects the second male connector 51 and the second female connector 52 to enhance the connection stability between them.

[0043] Furthermore, the second quick-release head 5 also includes a positioning pin 56. The second female connector 52 has a third mounting groove 523 on the side opposite to the second male connector 51. The third end 11 is inserted into the third mounting groove 523. At least two crimping parts 524 are provided at intervals along the groove depth direction of the third mounting groove 523 on the groove wall. The crimping parts 524 abut against the outer peripheral wall of the third end 11. A fourth through hole is provided through the outer peripheral wall of the second female connector 52. The fourth through hole is located between two adjacent crimping parts 524. The third through hole is provided on the outer peripheral wall of the third end 11. The positioning pin 56 is provided through the fourth through hole and the third through hole. Both ends of the positioning pin 56 are located on the outer side of the outer peripheral wall of the second female connector 52. Both ends of the positioning pin 56 are provided with abutting parts 561. The two abutting parts 561 abut against the outer peripheral wall of the second female connector 52 respectively.

[0044] After the third end 11 is inserted into the third mounting slot 523, the crimping mechanism is used to crimp the outer peripheral wall of the second female connector 52, which protrudes towards the central axis of the second female connector 52, thereby achieving a tight connection of the third end 11. The locating pin 56 further strengthens the connection between the third end 11 and the second female connector 52, preventing the third end 11 from coming out of the third mounting slot 523. The abutment part 561 enhances the connection stability between the locating pin 56 and the second female connector 52, preventing the locating pin 56 from coming out of the fourth through hole. Similarly, the fourth end 12 and the second male connector 51 can be connected in the same way as the second male connector 51 and the third end 11, which is convenient, quick, and provides a stable connection.

[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
