Description

Technical Field

[0001] The present invention relates to the technical field of underwater optical cables, and in particular to a scour protection device for offshore wind power cables. Background Art

[0002] In recent years, the offshore wind power industry has developed rapidly, and submarine cables have become the main means of offshore power transmission. During the use of submarine cables, due to the presence of wind turbine piles and protective tubes used to protect submarine cables, the flow pattern of the original ocean current in the local area is changed, and a high-intensity water turbulence and vortex system is generated around them, causing the protective tubes and submarine cables near the wind turbine piles to be suspended and swaying, which brings hidden dangers to the safe operation of wind farms.

[0003] In order to improve the connection between the cable and the ground, a protective shell is generally set on the surface of the cable to reduce the swing amplitude of the cable. However, some of the current protective devices are simple cable-to-ground connection devices that cannot provide buffering for the flow of water, thereby reducing the practicality of the device. In addition, algae will adhere to the surface of the cable during long-term use. If there are too many or too large organisms attached to the surface of the optical cable, it may cause severe mechanical pressure on the optical cable and even cause the optical cable to break.

The ratchet transmission member 105 is a prior art. When the rotation direction of the first transmission rod 104 is consistent with the working direction of the ratchet transmission member 105, the ratchet transmission member 105 can drive the oxygen supply mechanism 11 to work.

[0035] When the ratchet transmission member 105 drives the second transmission rod 111 to rotate, the belt transmission member 112 can be rotated, and then under the action of the belt transmission member 112, the third transmission rod 113 drives the fourth transmission rod 114 and the rotating wheel 115 to rotate, so that the protrusion 116 and the oxygen supply water pipe 117 are fitted together, and under the squeezing effect of the protrusion 116 on the oxygen supply water pipe 117, the external air enters the connecting shell 4 through the oxygen supply water pipe 117, and then oxygen is supplied to the inner cavity of the connecting shell 4, thereby improving the survival rate of crabs and improving the practicality of the device.

[0036] In addition, when the pressure in the inner cavity of the first piston head 92 changes, the pressure in the inner cavity of the third piston tube 122 can be changed under the action of the second connecting tube 121, and then under the action of the third piston head 123, the gas tank 125 can be sucked through the third connecting tube 124, and under the action of the fourth connecting tube 127, the fifth connecting tube 131 can work.

[0037] When there is gas flowing in the fifth connecting tube 131, the fourth piston head 133 in the fourth piston tube 132 can drive the action rod 134 to move, and then under the action of the driving rod 135 and the hinge plate 136, the reinforcing nail 137 emerges from the first connecting rod 6, thereby achieving the purpose of improving the connection between the first connecting rod 6 and the ground and improving the stability of the connecting shell 4 when it is at the bottom of the water.
