Abstract

The invention provides fan foundation protection throwing equipment. The fan foundation protection throwing equipment comprises a first throwing device and a second throwing device capable of being connected with the first throwing device in an oppositely-folded manner; and any throwing device comprises an internal throwing platform, a cylinder body, an external throwing platform and an unhookingmechanism, wherein the internal throwing platform is connected to the inner side of the cylinder body, the external throwing platform is connected to the outer side of the cylinder body, the unhookingmechanism comprises connecting rods and a plurality of unhooking assemblies, the multiple unhooking assemblies are arranged at the bottom of the internal throwing platform and the bottom of the external throwing platform at intervals and are in linkage through the connecting rods. According to the fan foundation protection throwing equipment, by arranging the throwing devices capable of being folded oppositely, hoisting throwing installation of a sand quilt can be completed, and protection of a fan foundation can be achieved easily. During throwing installation of the sand quilt, automatic unhooking of the sand quilt can be achieved, and operation is convenient. The fan foundation protection throwing equipment can be matched with fan pile bodies with different sizes to finish the throwinginstallation of the sand quilt.

Description

technical field [0001] The invention relates to the technical field of offshore wind turbine foundation protection, in particular to a wind turbine foundation protection throwing equipment with good waterproof and sealing performance. Background technique [0002] In the process of installation, operation and maintenance of offshore wind turbines, the foundation of the wind turbine is particularly important. How to ensure the bearing capacity of the fan foundation after installation and during use, and how to prevent quality and safety accidents caused by the reduction of the bearing capacity of the fan has always been a hot research object. [0003] Offshore wind turbines are subjected to long-term erosion by ocean currents during their service life. Due to the impact of the tower on the flow field, scour pits will be formed around the tower, which reduces the mud entry depth of the foundation cylinder and affects the bearing capacity of the foundation. The laying of sand...
