A gravity type offshore wind
turbine generator set foundation capable of being towed is composed of a connecting section, a foundation body, a gravel
pile and a floating box. The foundation body is composed of a foundation base and a
reinforced concrete conic cylinder, the foundation base comprises a bottom board and a rib board, the outer edge of the bottom board is provided with a bottom board ring beam, the circular bottom board is fixed to a rock foundation through grouting, and the top of the rib board is provided with a rib board ring beam; the top of a
reinforced concrete circular cylinder at the connecting section is connected with a fan
tower through a
flange; the floating box is a closed box body welded through steel and the top of the floating box and the bottom of the floating box are provided with an air discharging valve and a water discharging valve respectively; the floating box and the outer side rib board ring beam are provided with connecting components and connected through hinge pins so that the floating box can be fixed or retracted. The gravity type offshore wind
turbine generator set foundation has the advantages that the
gravity center of the gravity type offshore wind
turbine generator set foundation is low, the good stability and the safety are achieved in the
towing transportation process and the sinking process, the material use amount of the foundation is small,
prefabrication installation is convenient and rapid, the construction period is short, the construction cost is low, the economical efficiency is good, and popularization and application are facilitated.
