Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0022] Please refer to Figures 1 to 5 , the embodiments of the present utility model include:
[0023] Such as Figure 1 and Figure 2 shown, the circumferentially arranged multi-cable bundle fixing device includes: a bending preventer 3, a submarine cable jacket 4, a fixed seat 1 and a fixed plate 2. As Figure 4 shown, a through hole 13 is vertically arranged in the fixed seat 1 to reduce weight on the basis of ensuring the structural strength of the fixed seat 1 and improve the convenience of underwater installation construction.
[0024] Circumferentially spaced apart from the outside of the fixed seat 1 are first vertical grooves 11 corresponding one-to-one to the submarine cable jackets 4, and the submarine cable jackets 4 are respectively arranged in the first vertical grooves 11. In this embodiment, 4 submarine cables need to be fixed simultaneously, so 4 first vertical grooves 11 and submarine cable jackets 4 need to be arranged.
[0025] The fixed plate 2 is arranged outside the first vertical groove 11 to fix the submarine cable jacket 4. As Figure 5 shown, a second vertical groove 24 corresponding to the first vertical groove 11 is arranged inside the fixed plate 2, with a tight fit. In this embodiment, connecting plates 22 are arranged on both sides of the fixed plate 2, and third screws 23 connected to the fixed seat are arranged on the connecting plates 22, which is convenient for assembly.
[0026] Lifting lugs 21 are respectively arranged on the outside of the fixed plate 2, which is convenient for hoisting the fixed plate 2 or fixing it on the oil and gas platform to realize the bundled fixation of the fixed seat 1 and multiple submarine cables. Through this, 4 submarine cables can be circumferentially arranged and fixed by 4 submarine cable jackets 4, improving the space utilization rate and providing a new submarine cable landing method for oil and gas platforms without J-tube resources.
[0027] Such as Figure 3As shown in the figure, positioning grooves 43 are axially spaced on the outer wall of the submarine cable jacket 4. First bosses 12 corresponding to the positioning grooves 43 one by one are arranged in the first vertical grooves 11, and second bosses 25 corresponding to the positioning grooves 43 one by one are arranged in the second vertical grooves 24. In this embodiment, the positioning grooves 43 are annular grooves, and the first bosses 12 and the second bosses 25 respectively adopt semi-circular boss mechanisms to cooperate with the positioning grooves 43 to perform axial positioning of the submarine cable jacket 4 in the first vertical grooves 11 and the second vertical grooves 24, avoiding axial movement.
[0028] The anti-bending device 3 is arranged at one end or both ends of the submarine cable jacket 4 to provide anti-bending protection for the submarine cable through the anti-bending device 3. In this embodiment, the anti-bending device 3 is arranged at both ends of the submarine cable jacket 4 to provide anti-bending protection at both ends of the submarine cable jacket 4 simultaneously.
[0029] As Figure 3 shown in the figure, the submarine cable jacket 4 includes symmetric first arc-shaped clamping plates 41 and second arc-shaped clamping plates 42. The cross-sections of the first arc-shaped clamping plates 41 and the second arc-shaped clamping plates 42 are respectively semi-circular ring structures, which can clamp the submarine cable. The first arc-shaped clamping plates 41 and the second arc-shaped clamping plates 42 are connected and fixed through first screws 44 to ensure the clamping stability of the outer circle of a section of the submarine cable.
[0030] Semicircular ring pieces 45 located on the corresponding end faces of the fixed seat 1 are respectively arranged at both ends of the first arc-shaped clamping plates 41 and the second arc-shaped clamping plates 42. The semicircular ring pieces 45 can be welded to both ends of the first arc-shaped clamping plates 41 and the second arc-shaped clamping plates 42, with a firm structure. In this embodiment, the cross-sections of the first vertical grooves 11 and the second vertical grooves 24 are respectively semi-circular structures, and the outer circle radius of the semicircular ring pieces 45 is greater than the radius of the first vertical grooves 11 to prevent the semicircular ring pieces 45 from entering the first vertical grooves 11, further improving the axial stability of the submarine cable jacket 4 and the convenience of assembling with the fixed seat 1.
[0031] In this embodiment, the two semicircular ring pieces at the corresponding ends of the first arc-shaped clamping plates 41 and the second arc-shaped clamping plates 42 form an annular flange structure. A flange 31 is arranged on the anti-bending device 3, and a second screw 32 for connecting with the semicircular ring pieces 45 is arranged on the flange 31. Threaded holes 46 corresponding to the second screws 32 are arranged on the semicircular ring pieces 45. The use of the flange 3 and the second screws 32 not only realizes the fixation of the anti-bending device 3 but also improves the connection stability of the two symmetric semicircular ring pieces 45.
[0032] The specific installation process is as follows:
[0033] 1. Sleeve two anti-bending devices 3 on the specified position of the submarine cable at intervals up and down, clamp the specified position of the submarine cable with the first arc-shaped clamping plates 41 and the second arc-shaped clamping plates 42 of the submarine cable jacket 4, and lock them through the first screws 44;
[0034] 2. Fix the anti-bending device 3 at both ends of the submarine cable jacket 4 with the second screw 32;
[0035] 3. Push the submarine cable jacket 4 into the designated first vertical groove 11 on the outside of the fixed seat 1;
[0036] 4. Install the fixing plate 2 on the outside corresponding to the first vertical groove 11 to fix the submarine cable jacket 4, and install the third screw 23 for fastening;
[0037] 5. Install other submarine cables according to the above steps to achieve circumferential bundle fixing of multiple submarine cables on the outside of the fixed seat 1;
[0038] 6. Connect it to the bracket on the oil and gas platform through the ear seat 21 so that the submarine cable lands on the oil and gas platform.
[0039] In summary, a circumferentially arranged multi-cable bundle fixing device pointed out by the present utility model realizes circumferential bundle fixing of multiple submarine cables, is beneficial to landing on the oil and gas platform, and improves space utilization and flexibility of use.
