Technical Field

[0001] This invention relates to the field of marine engineering technology, and more specifically, to a cable clamp fixing device and method utilizing the pin holes of pile legs. Background Technology

[0002] Offshore engineering is complex and massive. Submarine fiber optic cable transmission systems consist of underwater and onshore equipment, employing redundant designs to ensure communication reliability. For jack-up platforms and other offshore cable landing points, a common method is to securely connect cables using cable clamps. However, the cable clamps on the cylindrical legs of jack-up platforms are not permanently fixed; they are installed when needed and removed when not. Since part of the jack-up platform's legs is submerged, this operation must be performed underwater, and traditionally removable bolts are not easily handled underwater. Summary of the Invention

[0003] The purpose of this invention is to provide a cable clamp fixing device and fixing method using the pin hole of the pile leg, so as to solve one or more problems mentioned in the background art.

[0004] To achieve the above objectives, a submarine cable clamp fixing device utilizing a pile leg pin hole includes a pin hole provided on the pile leg, an inner liner plate with a clamp installed inside the pin hole, the inner liner plate being secured by the pin hole, and the clamp extending out of the pin hole; an outer fixing plate is provided outside the pin hole, and the outer fixing plate and the inner liner plate are fixed by a connecting device.

[0005] As a preferred embodiment, the height of the inner liner is greater than the diameter of the pin hole to achieve the locking of the inner liner, and the width of the inner liner is smaller than the diameter to facilitate the use of the pin hole to remove and place the inner liner.

[0006] As a preferred embodiment, the connecting device includes multiple ear plates fixedly welded to the inner liner plate, each ear plate extending out of a pin hole, and an opening provided in the outer fixing plate to allow the ear plates of the inner liner plate to pass through. The ear plates are fixed by pins at positions outside the outer fixing plate.

[0007] As a preferred method, a limiting element is fixedly installed on the inner lining plate, and the limiting element abuts against the end of the pile leg near the pin hole.

[0008] As a preferred embodiment, the limiting element includes an upper limiting block and a lower limiting block, which are arc-shaped structures arranged along the circumferential edge of the pin hole.

[0009] As a preferred embodiment, the protruding end of the lower limit block is provided with a vertically downward hook, which is used to lock the edge of the pin hole to restrict the movement of the inner liner and the outer fixing plate.

[0010] As a preferred implementation method, the upper end of the upper limit block protruding end is beveled to facilitate the placement and removal of the inner lining plate.

[0011] As a preferred embodiment, the clamp includes a base and a clamp panel welded to the base, with the base and clamp panel welded together by continuous welding.

[0012] As a preferred feasible method, the connecting device consists of two ear plates symmetrically welded to the inner lining plate, and the welding method between the ear plates and the inner lining plate is a full penetration weld.

[0013] This application also provides a method for fixing submarine cables using the pin holes of the pile legs.

[0017] S4. Install the outer fixing plate, and align the reserved hole on the outer fixing plate with the ear plate position fixedly welded on the inner lining plate, so that the ear plate passes through the reserved hole;

[0018] S5. After the ear plate passes through the reserved hole, a movable pin is used on the right side of the outer fixing plate to fix the ear plate and the outer fixing plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention is simple to install and easy to disassemble. The device utilizes pin holes on the pile legs, with inner lining plates and outer fixing plates on the inner and outer sides of these holes.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] It should be noted that all uses of "first", "second", "third" and "fourth" in the embodiments of the present invention are for the purpose of distinguishing two entities with the same name but different names or different parameters. It is clear that "first", "second", "third" and "fourth" are only for the convenience of expression and should not be construed as limiting the embodiments of the present invention. Subsequent embodiments will not explain this in detail.

[0026] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, 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 limiting the scope of protection of this invention.

[0027] like Figure 1-3 As shown, a submarine cable clamp fixing device utilizing a pile leg pin hole includes a pin hole 2 on the pile leg 1. An inner lining plate 3 with a clamp is installed inside the pin hole 2, and the inner lining plate 3 is secured by the pin hole 2, with the clamp extending out of the pin hole 2. An outer fixing plate 4 is provided outside the pin hole 2, and the outer fixing plate 4 is fixed to the inner lining plate 3 by a connecting device. It should be noted that the inner lining plate should fully conform to the inner wall of the pile leg, thus the inner lining plate can be designed with an arc that adapts to the curvature of the inner side of the pile leg. Furthermore, the pin hole is originally present on the pile leg, and the original pin hole on the pile leg was used for lifting and lowering the pile leg.

[0028] Therefore, the present invention has solved the compatibility problem with the pile leg. The pile leg is provided with a pin hole, and an inner lining plate and an outer fixing plate are provided on the inner and outer sides of the pin hole. The inner lining plate and the outer fixing plate support each other. This structure is convenient for underwater operation, reduces the difficulty of underwater work, and thus reduces the amount of underwater work.

[0029] As shown in the figure, the height of the inner lining plate 3 is greater than the diameter of the pin hole 2, thus securing the inner lining plate 3. The width of the inner lining plate 3 is smaller than the diameter of the pin hole to facilitate the removal and placement of the inner lining plate 3 using the pin hole 2. This allows the inner lining plate to be inserted into the pin hole during use or removed from the pin hole when not in use. Therefore, the inner lining plate can easily extend into the pin hole, and the clamp can extend out of the pin hole.

[0030] As shown in the figure, the connecting device includes multiple ear plates fixedly welded to the inner lining plate 3. Each ear plate extends out of the pin hole 2. The outer fixing plate 4 has an opening to allow the ear plates of the inner lining plate 2 to pass through. A pin 5 is provided on the ear plate at a position outside the outer fixing plate 4, thereby fixing the outer fixing plate and the pin relatively. The pin can be a movable pin or similar mechanism, as long as it can lock the outer fixing plate and keep the outer fixing plate and ear plate relatively fixed. That is, a movable pin is provided on the ear plate on the side of the outer fixing plate away from the pin hole, thereby locking the outer fixing plate. This application can be configured with multiple ear plates and movable pins in combination for fixing according to the needs of actual engineering.

[0031] In this embodiment, the connecting device consists of two ear plates 10 symmetrically welded to the inner lining plate 3, and the welding method between each ear plate 10 and the inner lining plate 3 is full penetration welding.

[0032] More preferably, a limiting member is fixedly provided on the inner lining plate 3, and the limiting member abuts against the circumferential end of the pile leg 1 near the pin hole 2. The limiting member includes an upper limiting block 6 and a lower limiting block 7, which are arc-shaped structures set along the circumferential edge of the pin hole 2. Thus, this structure increases vertical stability.

[0033] Specifically, the protruding end of the lower limit block 7 is provided with a vertically downward hook 8, which is used to lock the edge of the pin hole 2 to restrict the movement of the inner liner 3 and the outer fixing plate 4. The upper end of the protruding end of the upper limit block 6 is beveled to allow the upper end to extend when the lower end of the inner liner is locked. Similarly, the side of the hook 8 near the inner liner can also be beveled to facilitate the removal and placement of the inner liner.

[0034] As shown in the figure, the clamp 9 includes a base 91 and a clamp panel 92 welded to the base 92. The base is a square steel base, and the base 91 and the clamp panel 92 are welded together by continuous welding.

[0035] This application also provides a method for fixing submarine cable clamps using the pin holes of the pile legs. The method, which uses the aforementioned submarine cable clamp fixing device using the pin holes of the pile legs, includes the following steps:

[0036] S1. Hold the inner lining plate with the clamp from the outside of the pile leg at an inclined angle and insert it into the pin hole on one side of the pile leg;

[0037] S2. Secure the lower limit block at the lower end of the inner lining plate to the lower edge of the pile leg pin hole;

[0038] S3. Straighten the inner liner plate so that the upper limit of the inner liner plate is locked at the upper edge of the pile leg pin hole;

[0039] S4. Install the outer fixing plate, and align the reserved hole on the outer fixing plate with the ear plate position fixedly welded on the inner lining plate, so that the ear plate passes through the reserved hole;

[0040] S5. After the ear plate passes through the reserved hole, a movable pin is used on the right side of the outer fixing plate to fix the ear plate and the outer fixing plate.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
