Description

Technical Field

[0001] The invention relates to the technical field of J-type cable tubes, and in particular to a J-type cable tube and a floating wind turbine generator set. Background Art

[0002] The J-type cable tube is one of the structures that the submarine cable must pass through when passing from the tower foundation to the sea. It is subject to the combined effects of multiple loads from the tower foundation, wave and current loads, and the submarine cable in the tube, and requires higher structural strength.

[0003] Since floating wind turbines are usually faced with variable and relatively extreme loads, the J-type cable pipes on floating wind turbines are subjected to greater load impacts. However, due to their low structural strength and low ability to resist load changes, the J-type cable pipes are often damaged, and their protective effect on submarine cables is insufficient, reducing the reliability of floating wind turbines.

[0004] Therefore, how to protect submarine cables through reasonable structural design and improve the reliability of floating wind turbines is a technical problem that technicians in this field currently need to solve. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a J-shaped cable pipe to improve the reliability of a floating wind turbine.

[0009] At least one J-shaped outer tube is arranged on the outside of the J-shaped inner tube, and the J-shaped outer tube naturally extends from the first inner branch tube to the second inner branch tube along the trajectory of the submarine cable channel. The J-shaped inner tube and the J-shaped outer tube and the adjacent J-shaped outer tubes are welded together through reinforcement members.

[0012] Preferably, in the above-mentioned J-shaped cable tube, the streamline is formed by a semicircle and two 1 / 4 circles being tangent to each other, or the streamline is in the shape of a sine curve within a period from -90° to 270°.

[0013] Preferably, in the above-mentioned J-type cable tube, a second cavity capable of accommodating the internal connecting tube is provided in the external connecting tube, and the external connecting tube naturally extends along the trajectory of the submarine cable channel from one end of the first external branch tube close to the external connecting tube to one end of the second external branch tube close to the external connecting tube, and shrinks into a circular tube of the same diameter and concentricity as the second external branch tube at the connection between the second external branch tube and the external connecting tube.

[0014] Preferably, the J-shaped cable tube further comprises a foamed corrosion-resistant material filled between the first inner branch pipe and the first outer branch pipe and between the inner connecting pipe and the outer connecting pipe.

[0016] Preferably, in the above-mentioned J-shaped cable tube, the outer wall of the J-shaped outer tube is provided with a flow-disturbing structure.

[0017] Preferably, in the above-mentioned J-shaped cable tube, the spoiler structure is an arc-shaped or spiral-shaped spoiler plate, or the spoiler structure is a triangular or rectangular spoiler patch.

[0018] Preferably, the J-shaped cable tube further comprises a clamping device capable of clamping the submarine cable, and the clamping device is arranged at an end of the second inner branch pipe away from the inner connecting pipe.

DETAILED DESCRIPTION

[0029] In view of this, the core of the present invention is to provide a J-shaped cable pipe to improve the reliability of a floating wind turbine.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 6 As shown, an embodiment of the present invention discloses a J-shaped cable tube, comprising a J-shaped inner tube 100 and a J-shaped outer tube 200 arranged outside the J-shaped inner tube 100 .

[0032] Among them, the J-shaped inner tube 100 includes a first inner branch tube 101, an internal connecting tube 102 and a second inner branch tube 103, the internal connecting tube 102 connects the first inner branch tube 101 and the second inner branch tube 103, and the first inner branch tube 101, the internal connecting tube 102 and the second inner branch tube 103 are welded in sequence to form a J-shaped submarine cable channel that allows the submarine cable 500 to pass through; the number of J-shaped outer tubes 200 is at least one, and the J-shaped outer tube 200 naturally extends from the first inner branch tube 101 to the second inner branch tube 103 along the trajectory of the coastal cable channel, and the J-shaped inner tube 100 and the J-shaped outer tube 200 and the adjacent J-shaped outer tubes 200 are welded together through reinforcement members 300.

[0033] When the J-shaped cable tube provided by the present invention is used, the submarine cable 500 is installed in a J-shaped submarine cable channel formed by welding the first inner branch tube 101, the internal connecting tube 102 and the second inner branch tube 103 in sequence; since at least one J-shaped outer tube 200 is arranged on the outside of the J-shaped inner tube 100, the J-shaped outer tube 200 naturally extends from the first inner branch tube 101 to the second inner branch tube 103 along the trajectory of the cable channel, so the J-shaped cable tube is a multi-layer tube structure including at least two layers of tubes; since the J-shaped inner tube 100 and the J-shaped outer tube 200 and the adjacent J-shaped outer tubes 200 are welded together through the reinforcement 300, the J-shaped cable tube has a higher overall structural strength. It can be seen that the J-type cable tube provided by the present invention has a multi-layer structure by providing a J-type outer tube 200, and each layer of the tube is welded together by a reinforcement member 300, thereby improving the structural strength of the J-type cable tube and the ability to resist load changes, reducing the damage frequency of the J-type cable tube, strengthening the protection of the submarine cable 500, and improving the reliability of the floating wind turbine.

[0034] It should be understood that the present invention does not specifically limit the parameters such as the diameter and length of the J-shaped inner tube 100 and the J-shaped outer tube 200. As long as the parameters can meet the use requirements, they belong to the protection scope of the present invention.

[0036] Furthermore, the reinforcement member 300 may be a rib plate, a bracket or a honeycomb reinforcement plate, etc. As long as the type can meet the mechanical performance requirements of the J-type cable tube, it belongs to the protection scope of the present invention; optionally, the reinforcement member 300 provided in the embodiment of the present invention is a rib plate.

[0037] like Figure 2 and Figure 3As shown, the number of ribs can be one, two or three, etc. The present invention does not specifically limit the number of ribs, as long as the number that can meet the use requirements belongs to the protection scope of the present invention; in addition, when the number of ribs is multiple, the ribs can be evenly distributed, randomly distributed or arrayed along the outer circumference of the J-shaped inner tube 100 between the J-shaped inner tube 100 and the first outer wall 2011 described below, as long as the distribution form that can meet the use requirements belongs to the protection scope of the present invention; optionally, in a specific embodiment provided by the present invention, the number of ribs is one, one end of the rib is welded to the J-shaped inner tube 100, and the other end is welded to the first outer wall 2011 of the J-shaped outer tube 200, and forms a "T" shape with the first outer wall 2011; in another specific embodiment provided by the present invention, the number of ribs is two, one end of the two ribs are welded to the J-shaped inner tube 100, and the other end is welded to the first outer wall 2011 of the J-shaped outer tube 200, and forms a "π" shape with the first outer wall 2011.

One end of the outer connecting tube 202 is welded to the first outer branch tube 201, and the other end is welded to the second outer branch tube 203, so that the first outer branch tube 201 and the second outer branch tube 203 are connected as a whole through the external connecting tube 202.

[0039] It should be noted that the above-mentioned second external branch tube 203 and the second internal branch tube 103 can be an integrally formed part, that is, the second external branch tube 203 and the second internal branch tube 103 are the same part, and the external connecting tube 202 naturally extends along the trajectory of the coastal cable channel from the end of the first external branch tube 201 close to the external connecting tube 202 to the end of the second external branch tube 203 (that is, the second internal branch tube 103) close to the external connecting tube 202, and then the external connecting tube 202 is directly welded to the second external branch tube 203 (that is, the second internal branch tube 103); or the second external branch tube 203 is a circular tube that is sleeved on the outer circumference of the second internal branch tube 103, and the second external branch tube 203 and the second internal branch tube 103 are connected together by an additionally arranged connecting piece; preferably, in an embodiment of the present invention, the second external branch tube 203 and the second internal branch tube 103 are an integrally formed part, that is, the second external branch tube 203 and the second internal branch tube 103 are the same part, so as to reduce the number of parts and components and reduce costs.

[0040] Specifically, the first external branch pipe 201 includes a first outer wall 2011 that can be fitted with the tower and a second outer wall 2012 welded to the first outer wall 2011. After welding, the first outer wall 2011 and the second outer wall 2012 form a first cavity 2013 that can accommodate the first internal branch pipe 101, so that the first internal branch pipe 101 can be arranged in the first cavity 2013; and the cross-section of the second outer wall 2012 in a plane perpendicular to the length direction of the first external branch pipe 201 is streamlined, so as to reduce the hydrodynamic load on the J-shaped cable pipe through the streamlined structure.

As long as the streamlined shape can meet the use requirements, it belongs to the protection scope of the present invention.

[0042] Furthermore, a second cavity 2021 capable of accommodating the internal connecting tube 102 is provided in the external connecting tube 202, and the external connecting tube 202 naturally extends along the trajectory of the coastal cable channel from one end of the first external branch tube 201 close to the external connecting tube 202 to one end of the second external branch tube 203 close to the external connecting tube 202, so as to form a second cavity 2021 capable of accommodating the internal connecting tube 102, and at the same time, the first external branch tube 201 and the second external branch tube 203 are connected by a naturally extended bend pipe; and the external connecting tube 202 is contracted into a circular tube of equal diameter and concentricity with the second external branch tube 203 at the connection between the second external branch tube 203 and the external connecting tube 202, so as to connect the external connecting tube 202 and the second external branch tube 203 together by welding.

[0043] The J-type cable tube provided by the present invention also includes a foamed corrosion-resistant material filled between the first inner branch tube 101 and the first outer branch tube 201 and between the inner connecting tube 102 and the outer connecting tube 202, that is, the foamed corrosion-resistant material is filled in the first cavity 2013 and the second cavity 2021, so as to provide a certain supporting strength through the foamed corrosion-resistant material to improve the stability of the J-type cable tube.

[0044] It should be understood that the above-mentioned foamed corrosion-resistant material can be foam plastic, foam rubber or resin and other types of materials. As long as the material can meet the use requirements, it belongs to the protection scope of the present invention.

[0045] In addition, the submarine cable channel provided by the present invention can be a variable diameter channel, or the total diameter can be a fixed value. As long as the submarine cable channel can meet the use requirements, it belongs to the protection scope of the present invention; optionally, the total diameter of the submarine cable channel provided in the embodiment of the present invention is a fixed value, that is, the diameters of the first internal branch pipe 101, the internal connecting pipe 102 and the second internal branch pipe 103 are equal.

[0046] In addition, the above-mentioned submarine cable channel is filled with anti-corrosion and waterproof grease to protect the submarine cable 500.

[0047] Furthermore, the outer wall of the J-shaped outer tube 200 is provided with a spoiler structure 204 so as to destroy the vortex near the J-shaped cable tube through the spoiler structure 204, reduce the damage of the J-shaped cable tube caused by vortex-induced vibration, and extend the service life of the J-shaped cable tube.

[0048] The above-mentioned spoiler structure 204 can be a spoiler plate or a spoiler patch, etc., as long as the type that can meet the use requirements belongs to the protection scope of the present invention; when the spoiler structure 204 is a spoiler plate, the spoiler plate can be in an arc shape or a spiral shape, etc., when the spoiler structure 204 is a spoiler patch, the spoiler patch can be in a triangular or rectangular shape, etc., as long as the type that can meet the use requirements belongs to the protection scope of the present invention; optionally, as Figure 4 As shown, the spoiler structure 204 provided in the embodiment of the present invention is an arc-shaped spoiler.

[0049] It should be understood that the distribution form of the above-mentioned arc-shaped spoilers on the outer wall of the J-shaped outer tube 200 can be random distribution, array distribution or uniform distribution along a certain direction. As long as the distribution form can meet the use requirements, it belongs to the protection scope of the present invention. In actual applications, the installation position and distribution form of the spoilers, as well as the shape, width and thickness of the spoilers can be adaptively adjusted according to the fluid simulation results.
