In this embodiment, the sacrificial anode block 4 is a negative electrode, the pile foundation 1 is a positive electrode, the sacrificial anode block 4 is in contact with the wall surface of the installation groove 21 and is soaked in seawater, and after a period of time, the sacrificial anode block 4 is gradually corroded, so that the pile foundation 1 is protected, and the service life of the pile foundation 1 is further prolonged. The volume of the sacrificial anode block 4 is gradually reduced in the process of being corroded, the sacrificial anode block 4 is gradually moved to the lower part of the installation groove 21 under the action of gravity, and a worker can replace a new sacrificial anode block 4 at any time. The sacrificial anode block 4 and the wall surface of the mounting groove 21 can slide relatively, and the sacrificial anode block 4 and the mounting groove 21 do not need to be fixedly connected. During installation, the sacrificial anode block 4 is installed into the installation groove 21 through the opening, and when the sacrificial anode block 4 needs to be replaced, a worker takes the sacrificial anode block 4 out of the opening.

When the sacrificial anode block 4 is installed in the installation groove 21, the sacrificial anode block 4 can be directly contacted with the pile foundation 1. Therefore, the peripheral surface of the first part 11 can be directly used as a groove surface of the mounting groove 21, materials are saved, the sacrificial anode block 4 is directly contacted with the pile foundation 1, and the protection effect is better.
In some embodiments, the offshore wind power foundation with replaceable sacrificial anode blocks further comprises a mounting bracket, the mounting member 2 is connected with the mounting bracket, the mounting bracket is connected with the outer wall surface of the first part 11, the mounting member 2 is mounted on the first part 11 through the mounting bracket, and the mounting member 2 and the first part 11 have a space in the radial direction of the first part 11.
For example, the mounting members 2 are spaced apart from the first portion 11, mounting brackets (not shown) extend along the outer circumferential surface of the pile foundation 1, and the mounting brackets are constructed such that the plurality of mounting members 2 are integrated with the mounting brackets, and then the mounting brackets are fixed to the outer wall surface of the first portion 11.

The width of the window 230 is the dimension of the window 230 in the direction perpendicular to the extending direction thereof, and the width of the window 230 is smaller than the width of the sacrificial anode block 4, preventing the sacrificial anode block 4 from escaping from the window 230. Therefore, the window 230 can facilitate the staff to observe the position of the sacrificial anode block 4, and can increase the contact area of the sacrificial anode block 4 and the seawater to better protect the pile foundation 1.
