[0001] The utility model relates to the technical field of submarine cable clamp, more specifically, the utility model relates to a kind of offshore wind power submarine cable clamp device. BACKGROUND

[0002] At present, the existing submarine cable protection clamp, also known as submarine cable protection sleeve, plays an important role in the field of submarine cable protection, mainly used for protecting submarine cable and limiting its bending. It is equipped with a bending limiter, usually used in cooperation with J pipe sealing device or J pipe center clamp at the lower end of J pipe. The general bending limiter adopts a Havf type module unit structure, each unit is engaged with each other to form a chain, and adjacent units can move relatively, and can reach the minimum bending radius in the stress locking state. However, the existing chain structure composed of engagement has obvious defects. In the bending process, the units between the engagement need to bear the reverse force generated by bending, resulting in excessive stress, which is prone to edge deformation or cracking, and thus loses good bending resistance. This not only affects the performance of the submarine cable protection clamp, but also may pose a threat to the safe operation of the submarine cable. SUMMARY

[0003] In order to overcome the shortcomings of the prior art, the utility model provides a kind of offshore wind power submarine cable clamp device, with the advantage of protecting submarine cable.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: a kind of offshore wind power submarine cable clamp device, including upper clamp, the outer surface of the upper clamp movably installs lower clamp, the movably installed upper clamp and lower clamp have flexible frame, the flexible frame is movably installed with elastic plate in the inside;

[0005] Threaded holes are formed in the inside of the upper clamp and the lower clamp, the threaded holes are threaded with bolts, and the outer surface of the inside of the upper clamp and the lower clamp is provided with a ball.

[0006] As a preferred technical solution of the utility model, the balls are arranged in a circumferential array in the inside of the upper clamp and the lower clamp, and the number of balls is twenty-six.

[0007] As a preferred technical solution of the utility model, the inner diameter of the flexible frame is equal to the outer diameter of the elastic plate, and the inside of the flexible frame has a smooth surface design.

[0008] As a preferred technical solution of the utility model, the threaded holes and the balls are arranged in pairs, and two pairs of movable installation are arranged in the inside of the upper clamp and the lower clamp.

[0009] As a preferred technical solution of the utility model, the inside of the bolt is provided with a bolt hole, and the inside of the bolt hole is in the shape of a plum blossom.

[0010] As a preferred technical scheme of the utility model, the flexible frame and the elastic plate are made of neoprene.

[0011] As a preferred technical scheme of the utility model, the outer diameter value of one end of the upper clamp and the lower clamp is equal to the inner diameter value of the flexible frame, and the inner movable ball of the upper clamp and the lower clamp is attached to the inner wall of the flexible frame.

[0012] Compared with the prior art, the utility model has the beneficial effects as follows:

[0013] Compared with the traditional device, the device is convenient for reducing the friction and jamming of the upper clamp and the lower clamp through the cooperation between the flexible frame and the elastic plate. The flexible frame and the elastic plate have obvious advantages in dealing with the dynamic changes of the submarine cable due to their elasticity and deformation capacity. When the submarine cable vibrates, the impact force can be buffered to avoid excessive wear caused by the rigid contact between the clamp and the submarine cable, thereby prolonging the service life of the two. In the face of thermal expansion and contraction of the submarine cable, the flexible sealing structure can deform along with it and always tightly attach to prevent sealing from being not strict due to size changes, thereby ensuring stable sealing effect. In addition, the flexible frame and the elastic plate can fill the small gaps and uneven places on the surface of the submarine cable and the clamp, tightly wrap the submarine cable, effectively prevent seawater and moisture from entering, and also adapt to the changes of deep sea pressure, adjust the sealing pressure, reduce the corrosion risk of the submarine cable, and ensure the sealing reliability.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] As shown in Figures 1 to 7 The utility model provides a sea cable clamp device of offshore wind power, including upper clamp 1, the outer surface of upper clamp 1 is movably installed with lower clamp 2, and the movable installation of upper clamp 1 and lower clamp 2 has flexible frame 5, and the inside movable installation of flexible frame 6 has elastic plate 6.

[0024] The inside of upper clamp 1 and lower clamp 2 is provided with threaded hole 3, and the inside of threaded hole 3 is screwed with bolt 7, and the outer surface of the inside of upper clamp 1 and lower clamp 2 is installed with ball 4.

[0025] The staff places upper clamp 1 and lower clamp 2 on the outer surface of the sea cable, then the inside threaded hole 3 of upper clamp 1 and lower clamp 2 is slowly screwed into the inside threaded hole 3 by the rose screwdriver, and the inside threaded hole 3 of two bolts 7 is slowly screwed in, and now the fixing of upper clamp 1 and lower clamp 2 is completed, and at the same time, in the use process of upper clamp 1 and lower clamp 2, the elastic plate 6 is extruded in the inside of flexible frame 5 by upper clamp 1 and lower clamp 2, then the sliding of ball 4 in the inside of flexible frame 5 is carried out, so that one end of elastic plate 6 is inclined in the inside of flexible frame 5, and the other side of upper clamp 1 and lower clamp 2 is extruded downward by elastic plate 6, so that upper clamp 1 and lower clamp 2 are precisely sealed by flexible frame 5 and elastic plate 6, so that the sealing of upper clamp 1 and lower clamp 2 is completed.

[0026] Put the upper clamp 1 and the lower clamp 2 on the outer surface of the submarine cable, then put the upper clamp 1 and the lower clamp 2 inside the threaded hole 3, now slowly screw the bolt 7 into the inside of the threaded hole 3 through the Phillips screwdriver, slowly screw the bolt 7 into the inside of the threaded hole 3 through the two bolts 7, now complete the fixing of the upper clamp 1 and the lower clamp 2, at the same time, the upper clamp 1 and the lower clamp 2 are used in the process, the elastic plate 6 is extruded in the inside of the flexible frame 5 through the upper clamp 1 and the lower clamp 2, then the ball 4 slides in the inside of the flexible frame 5, so that one end of the elastic plate 6 inclines in the inside of the flexible frame 5, and the other side of the upper clamp 1 and the lower clamp 2 is extruded downward through the elastic plate 6, so that the upper clamp 1 and the lower clamp 2 are precisely sealed through the flexible frame 5 and the elastic plate 6, thereby completing the sealing of the upper clamp 1 and the lower clamp 2. Compared with the traditional device, the device is convenient for reducing the friction and jamming of the upper clamp 1 and the lower clamp 2 through the cooperation between the flexible frame 5 and the elastic plate 6. The flexible frame 5 and the elastic plate 6 have obvious advantages in dealing with the dynamic changes of the submarine cable due to their own elasticity and deformation ability. When the submarine cable vibrates, the impact force can be buffered to avoid excessive wear caused by rigid contact between the clamp and the submarine cable, thereby prolonging the service life of the two. In the face of thermal expansion and contraction of the submarine cable, the flexible sealing structure can deform with it, always closely fit, prevent the seal from being loose due to size changes, and ensure stable sealing effect. In addition, the flexible frame 5 and the elastic plate 6 can fill the small gap and unevenness between the submarine cable and the clamp surface, tightly wrap the submarine cable, effectively prevent seawater and moisture from entering, and also adapt to changes in deep sea pressure, adjust the sealing pressure, reduce the corrosion risk of the submarine cable, and ensure the reliability of the seal.

[0027] Among them, the balls 4 are in the form of a circumferential array inside the upper clamp 1 and the lower clamp 2, and the number of balls 4 is twenty-six.

[0028] Since the balls 4 are in the form of a circumferential array inside the upper clamp 1 and the lower clamp 2, and the number of balls 4 is twenty-six, it is convenient for the upper clamp 1 and the lower clamp 2 to bend inside the flexible frame 5, and the balls 4 roll on the inner wall of the flexible frame 5, ensuring the bending efficiency of the upper clamp 1 and the lower clamp 2 in the flexible frame 5, and reducing the friction of the upper clamp 1 and the lower clamp 2 in use.

[0029] Among them, the inner diameter of the flexible frame 5 is equal to the outer diameter value of the elastic plate 6, and the inside of the flexible frame 5 has a smooth surface design.

[0030] Since the inner diameter of the flexible frame 5 is equal to the outer diameter value of the elastic plate 6, and the inside of the flexible frame 5 has a smooth surface design, it is convenient for the elastic plate 6 to move up and down inside, ensuring the stability of the upper clamp 1 and the lower clamp 2 during bending.

[0031] Among them, the threaded holes 3 and the balls 4 are in pairs, and there are two groups of movable installations inside the upper clamp 1 and the lower clamp 2.

[0032] Since the threaded holes 3 and the balls 4 are two groups, a total of two groups are movably installed in the interiors of the upper clamp 1 and the lower clamp 2, the upper clamp 1 and the lower clamp 2 are fixedly installed through the cooperation between the threaded holes 3 and the balls 4, and the installation efficiency of the upper clamp 1 and the lower clamp 2 is ensured.

[0033] The bolt 7 is internally provided with a bolt hole 8, and the bolt hole 8 is in the shape of a plum blossom.

[0034] Since the bolt hole 8 is in the shape of a plum blossom in the interior of the bolt 7, the head of the plum blossom shape can adapt to various types of wrenches, including plum blossom wrenches and open-end wrenches, and actual operation provides more options, when a certain wrench is inconvenient to use, other suitable tools can be quickly replaced, and the working efficiency is improved.

[0035] The flexible frame 5 and the elastic plate 6 are made of neoprene rubber.

[0036] Since the flexible frame 5 and the elastic plate 6 are made of neoprene rubber, the neoprene rubber is inherently elastic and soft, which enables the flexible frame 5 and the elastic plate 6 to better adapt to the dynamic changes of the submarine cable, such as vibration and thermal expansion and contraction, thereby effectively buffering the impact force and avoiding excessive wear between the clamp and the submarine cable due to rigid contact.

[0037] The outer diameter value of one end of the upper clamp 1 and the lower clamp 2 is equal to the inner diameter value of the flexible frame 5, and the balls 4 movably installed in the interiors of the upper clamp 1 and the lower clamp 2 are attached to the inner wall of the flexible frame 5.

[0038] Since the outer diameter value of one end of the upper clamp 1 and the lower clamp 2 is equal to the inner diameter value of the flexible frame 5, and the balls 4 movably installed in the interiors of the upper clamp 1 and the lower clamp 2 are attached to the inner wall of the flexible frame 5, it is convenient for the upper clamp 1 and the lower clamp 2 to bend for use in the interior of the flexible frame 5, and the stability of the upper clamp 1 and the lower clamp 2 during use in the interior of the flexible frame 5 is ensured.

[0039] By designing and reforming the structure inside the bending limiter unit, when the submarine cable bends, the internal structure will be triggered, so that the movable space in the bending limiter unit is filled, and then there is no gap between the units and the unit sets are in full contact and wrapped between adjacent units, so that they form a whole structure, which fully shares the stress received by the submarine cable when it bends, and when the submarine cable returns to the state before bending, the movable space between adjacent unit sets is restored, the bending angle of the submarine cable is limited, and the stress caused by excessive bending is prevented, the service life of the submarine cable protection clamp is prolonged, and the original effect of the bending limiter is not affected.

[0040] The working principle and use process of the utility model are as follows:

[0041] The worker places the upper clamp 1 and the lower clamp 2 on the outer surface of the submarine cable, then slowly screws the bolt 7 into the inner threaded hole 3 of the upper clamp 1 and the lower clamp 2 through the Phillips screwdriver, and now the fixing of the upper clamp 1 and the lower clamp 2 is completed, and at the same time, the upper clamp 1 and the lower clamp 2 are used in the process of extruding the elastic plate 6 in the inner flexible frame 5, and then sliding through the ball 4 in the inner flexible frame 5, so that one end of the elastic plate 6 is inclined in the inner flexible frame 5, and the other side of the upper clamp 1 and the lower clamp 2 is extruded downward through the elastic plate 6, so that the upper clamp 1 and the lower clamp 2 are precisely sealed through the flexible frame 5 and the elastic plate 6, thereby completing the sealing of the upper clamp 1 and the lower clamp 2.
