In the prior art, CN202321315546.7 proposes a submarine cable support fixing device, which comprises two supports, a support plate and a plurality of fixing holes. The two supports are adapted to be fixed on the fan tower foundation platform and are arranged at intervals and adjacent to the tower hole of the tower. The support plate is connected to the top of the two supports and is located at the side of the tower. The height of the support plate is greater than or equal to the height of the tower hole of the tower, and is adapted to support the submarine cable. The plurality of fixing holes are arranged on the support plate and are adapted to fix the submarine cable through the connecting piece. The submarine cable support fixing device provided by the utility model supports and fixes the suspended submarine cable, reduces the wear of the surface of the submarine cable and improves the reliability of the power collection line. However, the height of the support cannot be adjusted. Since the reserved length of the submarine cable is different during laying, the suspended height of the submarine cable will be different, and the height of the support required in each fan pile foundation will also be different, which will greatly increase the manufacturing cost and processing difficulty of the device. At the same time, there is a lack of monitoring technology for the stability of the submarine cable support in the pile foundation and the hydrogen sulfide gas in the single pile foundation. SUMMARY
