Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for submarine cable installation, specifically a submarine cable support and adjustment device. Background Technology

[0002] After the submarine cable for offshore wind power is laid from the seabed to the wind turbine foundation platform, it extends from the wind turbine foundation platform and enters the tower through the tower wall hole on the outer wall of the tower. During this process, due to the large weight of the submarine cable, it is easy for the submarine cable to be suspended in the air. When the suspended length of the submarine cable is too large, it will be affected by the natural vibration of operation, the long-term scouring of ocean currents, and the impact and contact of maintenance vessels on the pile foundation cage, which will aggravate the continuous reciprocating wear between the submarine cable and the tower wall hole, resulting in damage to the submarine cable, which will eventually cause electrical failure and wind turbine shutdown.

[0003] To prevent excessively long suspended sections of submarine cables, support devices are added to the lower end of the cable to reduce the length of each suspended section. This reduces the impact of the external environment on the cable. However, simple support devices are insufficient to support the entire suspended cable and can easily cause significant support deviations in different areas of the suspended cable, making it difficult to achieve the best support effect. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a submarine cable support adjustment device that can adapt to different areas on a whole section of suspended submarine cable and ensure the support effect.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: a submarine cable support adjustment device, including a support platform, the lower end of which is connected to an adjustment mechanism for adjusting the height of the support platform. The adjustment mechanism includes two adjustment pins and two drive components for driving the two adjustment pins to move up and down. The two adjustment pins are respectively located on both sides of the lower end of the support platform. The support distance between the two adjustment pins is not less than 2 / 3 of the length of the support platform, and the support length of the two adjustment pins is not less than 2 / 3 of the width of the support platform.

[0006] Compared with existing technologies, the advantages of this utility model are as follows: On the submarine cable laying path on the wind turbine foundation platform, multiple height-adjustable support platforms support the submarine cable in different areas. The support height is higher near both ends and lower near the center, thus avoiding long-distance suspension of the submarine cable. This not only effectively reduces the impact of the external environment on the submarine cable and avoids wear, but also avoids excessive support that could cause the cable to bend horizontally, affecting its tension. Since the submarine cable is a heavy object, its support strength requirements are high. When adjusting the support height, it is necessary to ensure the stability of the upward force. The design ensures the support strength and stability by using a support distance between two adjusting pins that is not less than 2 / 3 of the length of the support platform and a support length between the two adjusting pins that is not less than 2 / 3 of the width of the support platform.

[0007] As an improvement of this utility model, two opposing arc-shaped blocks are fixedly connected to the support platform. The arc-shaped blocks are used to prevent the submarine cable from detaching from the support platform, and the concave surface of the arc-shaped blocks abuts against the submarine cable. Through this improvement, the support platform's support stability for the submarine cable is ensured, preventing the submarine cable from detaching from the support platform. At the same time, it also prevents the submarine cable from shaking between the two arc-shaped blocks at any time, causing wear and tear, and ensuring the quality of the submarine cable.

[0008] As an improvement of this utility model, the support platform is provided with multiple sets of fixing connection holes for fixed connection with the arc-shaped block. Each set of fixing connection holes includes multiple fixing connection holes arranged along the width direction of the support platform. The fixing connection holes are threaded holes. The multiple sets of fixing connection holes are evenly arrayed along the length direction of the support platform. Through this improvement, the design of multiple sets of fixing connection holes can increase the applicability of the support platform to submarine cables of different diameters, and the design of multiple fixing connection holes in a set of fixing connection holes can ensure the connection stability between the arc-shaped block and the support platform.

[0009] As an improvement of this utility model, the upper edges of the support platform on both sides along the axial direction of the submarine cable are rounded. This improvement protects the submarine cable and prevents wear between the submarine cable and the edge of the support platform.

[0010] As an improvement of this utility model, driving connecting teeth are provided on both sides of the adjusting gear column, and the driving assembly includes two driving gears, which mesh with both sides of the adjusting gear column respectively. Through this improvement, the driving stability and driving strength of the adjusting gear column are guaranteed.

[0011] As an improvement of this utility model, the two drive gears are synchronously driven and connected by a drive motor, and the two drive gears rotate in opposite directions. This improvement ensures the driving synchronicity of the two drive gears and also ensures the consistency of the driving force direction of the two drive gears on the adjusting gear column.

[0012] As an improvement of this utility model, the drive gear is disposed in an adjustment box, the adjustment column passes longitudinally through the adjustment box, the length of the connection between the adjustment box and the adjustment column is greater than two tooth pitches of the adjustment column, and the meshing point between the drive gear and the adjustment column is disposed in the adjustment box. Through this improvement, the longitudinal movement stability of the adjustment column can be stabilized by setting the adjustment box, and the connection stability between the adjustment column and the drive gear can be protected to avoid external interference.

[0013] As an improvement of this utility model, the bottom of the adjustment box is provided with a support bracket. Through this improvement, the height of the adjustment box can be raised, and the adjustment gear can pass downward through the adjustment box to increase the height adjustment range of the adjustment gear.

[0014] As an improvement of this utility model, there are two support legs, which are located on opposite sides of the two adjusting pinions. This improvement ensures the stability of the support legs. At the same time, the two adjusting pinions are located between the two support legs. When the height is adjusted by adjusting the pinions, the reaction force of the submarine cable is close to the centerline of the support legs, making it less likely to tip over.

[0020] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0021] like Figure 1-2 As shown, a submarine cable support adjustment device includes a support platform 1. The lower end of the support platform 1 is connected to an adjustment mechanism 2 for adjusting the height of the support platform 1. The adjustment mechanism 2 includes two adjustment pins 2.1 and two drive components 2.2 for driving the two adjustment pins 2.1 to move up and down. The two adjustment pins 2.1 are respectively located on both sides of the lower end of the support platform 1. The support distance between the two adjustment pins 2.1 is not less than 2 / 3 of the length of the support platform 1, and the support length of the two adjustment pins 2.1 is not less than 2 / 3 of the width of the support platform 1.

[0022] like Figure 1 , Figure 3 As shown, two opposing arc-shaped blocks 3 are fixedly connected to the support platform 1. The arc-shaped blocks 3 are used to prevent the submarine cable from detaching from the support platform 1, and the concave surface of the arc-shaped blocks 3 abuts against the submarine cable. The support platform 1 is provided with multiple sets of fixing connection holes for fixing the arc-shaped blocks 3. Each set of fixing connection holes includes two fixing connection holes 1.1 arranged along the width direction of the support platform 1. The fixing connection holes 1.1 are threaded holes. The multiple sets of fixing connection holes are evenly arrayed along the length direction of the support platform 1. Two limiting countersunk through holes 3.1 are provided on the concave surface of the arc-shaped blocks 3 to cooperate with the fixing connection hole sets. Then, bolts are threadedly fixed to the fixing connection holes 1.1 by passing through the limiting countersunk through holes 3.1. The bolt nuts are recessed into the concave surface and limited on the arc-shaped blocks 3. The upper edges of both sides of the support platform 1 along the axial direction of the submarine cable are rounded.

[0023] like Figure 2 , Figure 4As shown, the adjusting gear 2.1 has driving connecting teeth 2.1.1 on both sides. The driving assembly 2.2 includes two driving gears 2.2.1, which mesh with the two sides of the adjusting gear 2.1 respectively. The two driving gears 2.2.1 are synchronously driven by a driving motor 2.2.2. The two driving gears 2.2.1 rotate in opposite directions. The driving gears 2.2.1 are housed in an adjusting box 4. The adjusting gear 2.1 passes longitudinally through the adjusting box 4. The adjusting box 4 and the adjusting gear 2.1 are connected. The length of the connection point is greater than two tooth pitches of the adjusting gear 2.1. The meshing point between the drive gear 2.2.1 and the adjusting gear 2.1 is located inside the adjusting box 4. On one side of the adjusting box 4, there is a motor box 2.2.3 for placing the drive motor 2.2.2. The motor box 2.2.3 is also equipped with a gear set, which includes an output gear 2.2.4 at the output end of the drive motor 2.2.2, two connecting gears 2.2.5 that rotate coaxially with the drive gear 2.2.1, and an adjusting gear 2.2.6 for adjusting the rotation direction of one of the connecting gears 2.2.5. At the intersection of the adjusting box 4 and the adjusting gear 2.1, the adjusting box 4 is provided with an extension frame 4.1 arranged along the moving direction of the adjusting gear 2.1. The extension frame 4.1 is provided to ensure that the length of the connection between the adjusting box 4 and the adjusting gear 2.1 is greater than two tooth pitches of the adjusting gear 2.1, thereby ensuring the accuracy and stability of the movement of the adjusting gear 2.1. Similarly, this purpose can also be achieved by increasing the thickness of the adjusting box 4, but the cost is high and the weight of the adjusting box 4 will also increase significantly.

[0024] like Figure 1-2 As shown, the bottom of the regulating box 4 is provided with a support frame 5. There are two support frames 5, which are located on opposite sides of the two regulating gear columns 2.1.
