1. A damper position-limiting device, configured to be mounted in a tower to limit a swing amplitude of a damper mounted in the tower, comprising at least one web and a position-limiting ring, wherein
the web has a mounting hole and at least one stress relief hole;
a first side wall of the web has a first specified length along a circumferential direction of an inner wall of the tower, and is connected to the inner wall of the tower; and
the position-limiting ring is positioned within the mounting hole and connected to the mounting hole and is configured to accommodate an impacting plate of the damper,
wherein the first specified length of the first side wall is 0.25 to 0.5 times a circumference of a specified periphery of the inner wall, the first side wall matching with the specified periphery of the inner wall at a specified height.
