[0036] The offshore photovoltaic cluster sea-land cable transfer laying, fixing and conversion platform comprises a cable sea-land conversion platform, and the cable sea-land conversion platform comprises a platform truss structure 1, a support pile 2, a submarine cable pipe 3, a submarine cable 4, a land cable 5 and a sea-land cable joint box 6. The platform truss structure 1 is formed with an accommodation space; the support pile 2 is used for supporting the platform truss structure 1; the submarine cable pipe 3 is arranged through the platform truss structure 1, one end of the submarine cable pipe 3 is communicated with the inside of the accommodation space, and the other end of the submarine cable pipe 3 is connected to the outside of the accommodation space; the submarine cable 4 is arranged through the submarine cable pipe 3, and the submarine cable 4 extends from the outside of the platform truss structure 1 to the inside of the platform truss structure 1; the land cable 5 is located in the inside of the platform truss structure 1; and the sea-land cable joint box 6 is connected between the submarine cable 4 and the land cable 5.
