Cable crossing structure for offshore wind turbine and offshore wind turbine thereof

Abstract

The invention discloses a cable crossing structure for an offshore wind turbine and the offshore wind turbine of the cable crossing structure. The cable crossing structure for the offshore wind turbine comprises a metal tube main body and a sheath main body, wherein the sheath main body is provided with an inserting part, a blocking part and a cable inserting port, the inserting part is inserted into the metal tube main body, the cable inserting port is used for being inserted by a cable, the sheath main body is made of elastic materials, the outer diameter of the blocking part is greater than that of the inserting part, the inner diameter of the metal tube main body is greater than or equal to that of the inserting part, and the outer diameter of the blocking part is greater than the inner diameter of the metal tube main body. The cable crossing structure for the offshore wind turbine disclosed by the invention has the beneficial effects that the metal tube main body and the sheath main body are arranged, the cable penetrates through the sheath main body, and then the cable is inside the metal tube main body to lower influences of the cable for sea breeze or sun and avoid direct artificial treading, furthermore, the sheath main body made of the elastic materials is arranged, so that the joint of the metal tube main body and the sheath main body is in elastic contact, to protect the outer surface of the cable from being scratched to greatly protect the appearance of the cable so as to avoid direct grounding or ground discharge of the cable.

Description

Technical field [0001] The invention relates to the field of offshore wind power generators, in particular to a cable routing structure used for offshore wind turbines and the offshore wind turbines. Background technique [0002] Most of the power and control cables of offshore wind turbines use snake-skin tubes for threading and guidance. Due to the harsh operating conditions of offshore wind turbines and large internal vibrations, the traditional snake-skin tubes have a very good anti-wear protection effect on their internal cables. Small, after long-term operation of offshore wind turbines, sea breeze and sunlight will have a greater impact on the snakeskin tube, and there are also reasons such as artificial stepping back and forth. The cable sheath often ruptures, causing the conductor to directly ground or discharge to the ground, which is harmful to equipment and personnel. Safety poses a serious threat; in addition, the interface of the snake skin tube is easily rubbed wit...

AI Technical Summary

Problems solved by technology

[0002] Most of the power and control cables of offshore wind turbines are threaded and guided by snakeskin tubes. Due to the harsh operating conditions of offshore wind turbines and large internal vibrations, traditional snakeskin tubes have little effect on the protection against wear and tear on the internal cables. Small, after the long-term operation of offshore wind turbines, the sea wind and the sun have a greater impact on the snake skin tube, and there are also reasons such as manual trampling back and forth, and the cable sheath often breaks, causing the wire to be directly grounded or discharged to the ground, which is harmful to equipment and personnel. It poses a serious threat to safety; in addition, the interface where the snake skin tube is threaded is easily rubbed against the cable by vibration, causing the outer skin of the cable to be worn, and it will also cause the wire to be directly grounded or discharge to the ground, posing a serious threat to the safety of equipment and personnel.
