Description

Technical Field

[0001] This utility model relates to the field of submarine cable clamp technology, and in particular to a submarine cable clamp device for offshore wind power. Background Technology

[0002] Offshore wind power is characterized by abundant resources, high power generation utilization hours, no land occupation, and suitability for large-scale development. It is the latest frontier in global wind power development. Submarine cables are commonly used power transmission channels in offshore wind power. During the laying process, clamping devices are needed to hold and fix the submarine cables in place.

[0003] Existing clamping devices typically consist of two arc-shaped clamps. During clamping, the submarine cable is passed through the two arc-shaped clamps, and then bolts are used to fix the two clamps together, securing the cable. However, in use, workers need to use wrenches or other tools to turn the bolts to ensure the two arc-shaped clamps firmly hold the cable in place. Furthermore, after clamping the cable, the clamping device needs to be installed inside a J-shaped tube and sealed. However, existing clamping devices generally only have a sealing ring on the outer surface of the clamp for sealing. Because the sealing ring cannot tightly abut against the inner wall of the J-shaped tube during installation, the sealing performance is poor. Therefore, we propose a new offshore wind power cable clamping device. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a marine wind power cable clamping device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a marine wind power cable clamping device is designed, including a first clamping plate and a second clamping plate. Both the first clamping plate and the second clamping plate are arc-shaped structures and are arranged opposite to each other. Two support blocks are symmetrically installed on one side of the first clamping plate. A second connecting block is vertically installed on the top of each support block. A first connecting block is symmetrically installed on the side of the second clamping plate near the second connecting block. Each first connecting block is rotatably connected to the corresponding second connecting block through a rotating shaft.

[0006] Two pairs of first arc-shaped limiting plates are symmetrically installed at both ends of the first clamping plate. Two fixing plates are installed on the side of each pair of first arc-shaped limiting plates away from the second connecting block. There is a gap between the bottom of the two fixing plates and the side of the first clamping plate. An adjusting shaft is rotatably connected between the two fixing plates. The side of the adjusting shaft is equipped with an external thread. Two pairs of second arc-shaped limiting plates are symmetrically installed at both ends of the second clamping plate. Locking bands are installed on the side of both ends of the second clamping plate. The locking bands are located between each pair of second arc-shaped limiting plates. One end of the locking band passes through the gap between the bottom of the two fixing plates and the first clamping plate. Several adjusting grooves are opened on the side of the locking bands. The adjusting grooves are engaged with the external thread.

[0007] Both the first and second clamping plates are equipped with arc-shaped fixing blocks on their sides, and each arc-shaped fixing block is equipped with an arc-shaped connecting block on its side. The two arc-shaped connecting blocks are connected on one side by a sealing sleeve.

[0008] Several support plates are installed inside the sealing sleeve at one end. Elastic gaskets are installed on the side of the support plates away from the sealing sleeve. The other end of each elastic gasket is fixed to the side of the corresponding first and second clamping plates.

[0009] Preferably, the outer surface of the locking band is clearance-fitted with the side of the first clamping plate and the bottom of the two fixing plates, and the two sides of the locking band are clearance-fitted with the adjacent surfaces of each pair of second arc-shaped limiting plates and each pair of first arc-shaped limiting plates.

[0010] Preferably, the bottom of the external thread extends to the bottom of the fixing plate.

[0011] Preferably, the sealing sleeve is made of an elastic sealing rubber material.

[0012] Preferably, one end of the support block, the first connecting block, and the second connecting block is located between two pairs of first arc-shaped limiting plates and two pairs of second arc-shaped limiting plates.

[0013] Preferably, the adjacent ends of two adjacent support plates are provided with matching inclined grooves, so that when the first clamping plate and the second clamping plate retract, the adjacent ends of the two adjacent support plates are stacked together.

[0014] Preferably, both the first and second clamping plates have a bevel at one end.

[0015] The design scheme proposed in this utility model has the following beneficial effects in application:

[0016] 1. By rotating the adjusting shaft, the locking band can be moved through the cooperation of the adjusting groove and the external thread, thereby controlling the contraction of the first and second clamping plates to clamp and fix the submarine cable, which is convenient for fixing.

[0017] 2. The elastic force of the elastic gasket can push the support plate to open the sealing sleeve, so that the sealing sleeve can fully seal with the inner wall of the J-shaped tube, thereby improving the sealing effect. Attached Figure Description

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-Figure 5 A submarine cable clamping device for offshore wind power includes a first clamping plate 1 and a second clamping plate 9. Both the first clamping plate 1 and the second clamping plate 9 are arc-shaped structures and are arranged opposite each other. Two support blocks 16 are symmetrically installed on one side of the first clamping plate 1. A second connecting block 17 is vertically installed on the top of each support block 16. A first connecting block 15 is symmetrically installed on the side of the second clamping plate 9 near the second connecting block 17. Each first connecting block 15 is rotatably connected to the corresponding second connecting block 17 through a rotating shaft. In actual use, the other ends of the first clamping plate 1 and the second clamping plate 9 can be separated along the rotating shaft, which can increase the space between the first clamping plate 1 and the second clamping plate 9, making it convenient to pass the submarine cable between the first clamping plate 1 and the second clamping plate 9.

[0026] like Figure 1As shown, two pairs of first arc-shaped limiting plates 2 are symmetrically installed at both ends of the first clamping plate 1. Two fixing plates 6 are installed on the side of each pair of first arc-shaped limiting plates 2 away from the second connecting block 17. There is a gap between the bottom of the two fixing plates 6 and the side of the first clamping plate 1. An adjusting shaft 7 is rotatably connected between the two fixing plates 6. The side of the adjusting shaft 7 is fitted with an external thread 5. Two pairs of second arc-shaped limiting plates 19 are symmetrically installed at both ends of the second clamping plate 9. Locking bands 3 are installed on the side of both ends of the second clamping plate 9. The locking bands 3 are located between each pair of second arc-shaped limiting plates 19, and one end of the locking band 3 extends from the two fixing plates 6. The gap between the bottom and the first clamping plate 1 is through which the locking band 3 passes, and several adjustment grooves 8 are provided on the side of the locking band 3. The bottom of the external thread 5 extends to the bottom of the fixing plate 6. The adjustment grooves 8 and the external thread 5 are engaged. In actual use, after the submarine cable is passed between the first clamping plate 1 and the second clamping plate 9, the operator can pass one end of the locking band 3 through the bottom of the two fixing plates 6, so that the adjustment grooves 8 on the side of the locking band 3 are engaged with the external thread 5. Then the operator can rotate the adjustment shaft 7 to control the movement of the locking band 3, tighten the first clamping plate 1 and the second clamping plate 9, and clamp and fix the submarine cable, which is convenient.

[0027] It should be noted that the outer surface of the locking band 3 is fitted with the side of the first clamping plate 1 and the bottom of the two fixing plates 6 with a gap, and the two sides of the locking band 3 are fitted with the adjacent surfaces of each pair of second arc-shaped limiting plates 19 and each pair of first arc-shaped limiting plates 2 with a gap. In this way, the fixing plates 6 can initially limit the locking band 3, and the first arc-shaped limiting plates 2 and the second arc-shaped limiting plates 19 can further limit the locking band 3, so as to prevent the locking band 3 from shaking during use.

[0028] like Figure 1 and Figure 3 As shown, arc-shaped fixing blocks 10 are installed on the sides of both the first clamping plate 1 and the second clamping plate 9. Arc-shaped connecting blocks 11 are installed on the sides of each arc-shaped fixing block 10. One side of the two arc-shaped connecting blocks 11 is connected by a sealing sleeve 12. In actual use, after clamping and fixing the submarine cable, the first clamping plate 1 and the second clamping plate 9 need to be installed inside the J-shaped tube. In this way, the sealing sleeve 12 will be in close contact with the inner wall of the J-shaped tube to complete the seal.

[0029] like Figure 2 and Figure 3 As shown, a number of support plates 13 are installed at one end of the inner side of the sealing sleeve 12. Elastic gaskets 14 are installed on the side of the support plates 13 away from the sealing sleeve 12. The other end of the elastic gaskets 14 is fixed to the side of the corresponding first clamping plate 1 and second clamping plate 9. In actual use, the support plates 13 will be pushed to expand under the action of the elastic gaskets 14, so that the side of the sealing sleeve 12 is in close contact with the inner wall of the J-shaped tube, thereby improving the sealing effect.

[0030] It should be noted that, as Figure 4 As shown, the adjacent ends of two adjacent support plates 13 are provided with matching inclined grooves 18. When the first clamping plate 1 and the second clamping plate 9 are contracted, the adjacent ends of the two adjacent support plates 13 are stacked together. In actual use, the adjacent ends of the two adjacent support plates 13 are stacked together, so that the sealing sleeve 12 can be fully supported in the state of contraction or expansion of the support plates 13, thereby improving the use effect.

[0031] Specifically, during installation, the operator rotates the first clamping plate 1 and the second clamping plate 9 along the pivot, opening one end of each clamping plate. The submarine cable is then inserted between the first clamping plate 1 and the second clamping plate 9. Next, one end of the locking strap 3 is inserted into the bottom of the fixing plate 6, causing the adjusting groove 8 on the locking strap 3 to engage with the external thread 5. The operator then rotates the adjusting shaft 7, which drives the external thread 5 to rotate. With the cooperation of the adjusting groove 8, the locking strap 3 can move, tightening the first clamping plate 1 and the second clamping plate 9, thereby clamping and fixing the submarine cable. This is convenient. The first clamping plate 1 and the second clamping plate 9 are then installed inside the J-shaped tube. During installation, when moving the first clamping plate 1 and the second clamping plate 9 into the J-shaped tube, as... Figure 5 As shown, one end of the sealing sleeve 12 is squeezed by the inner wall of the J-shaped tube. When the sealing sleeve 12 contracts, it squeezes the support plate 13, which in turn causes the elastic gasket 14 to deform under force. Thus, during installation, under the elastic force generated by the deformation of the elastic gasket 14, the support plate 13 can push the sealing sleeve 12 tightly against the inner wall of the J-shaped tube to complete the seal, resulting in a good sealing effect.

[0032] Furthermore, the sealing sleeve 12 is made of elastic sealing rubber material, or other elastic corrosion-resistant sealing material, so that the sealing sleeve 12 will deform with the contraction and expansion of the first clamping plate 1 and the second clamping plate 9, without hindering the sealing effect.

[0033] Furthermore, such as Figure 5 As shown, one end of the support block 16, the first connecting block 15, and the second connecting block 17 are all located between the two pairs of first arc-shaped limiting plates 2 and the two pairs of second arc-shaped limiting plates 19, so that the support block 16, the first connecting block 15, and the second connecting block 17 will not obstruct the installation of the first clamping plate 1 and the second clamping plate 9 inside the J-shaped tube.

[0034] Furthermore, such as Figure 1 As shown, both the first clamping plate 1 and the second clamping plate 9 have an inclined surface 4 at one end. The inclined surface 4 can guide the first clamping plate 1 and the second clamping plate 9 when they are installed in the J-shaped tube, reducing the difficulty of installation.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
