In some possible embodiments, the support structure 11 comprises: a cover plate 111, a connecting rod 112 and a base plate 113.

One end of the connecting rod 112 is detachably connected with the cover plate 111; the other end of the connecting rod 112 is detachably connected to the base plate 113.

The other end of the connecting rod 112 is also detachably connected to one side of the C-shaped connecting beam 122.

One side of the base plate 113 near the cover plate 111 is for contacting one end of the damper 20.

In this embodiment, as shown in fig. 1, the bottom plate 113 is connected to the damper 20, and the connecting rod 112 limits the damper 20 at the side to prevent the stacked dampers 20 from being dislocated. The cover plate 111 is disposed over the damper 20 to protect the damper 20. One end of the connecting rod 112 is connected to the cover plate 111, and the other end is connected to the base plate 113.

That is, the other end of the connecting rod 112 is connected to both the C-shaped connecting beam 122 and the base plate 113, that is, one end of the connecting rod 112 is connected to the base plate 113 at a side close to the damper 20, and the end is connected to the C-shaped connecting beam 122, so that the connection between the entire structure of the base plate 113 and the C-shaped connecting beam 122 is more stable.

Alternatively, in order to make the damping fluid in the damper 20 directly flow into the first fluid collecting structure 13 when the damping fluid leaks, a certain hollow may be designed on the bottom plate 113.

Since the damper 20 may have different pressure-bearing capacities due to stress, heat, and the like during the process of manufacturing the damper 20, when the damper 20 is disposed on the bottom plate 113, the tightness between the connecting rod 112 and the damper 20 may be changed according to the pressure-bearing capacity of each damper 20, and the required pre-tightening force, reliability, and strength between the damper 20 and the mounting structure 10 are finally achieved.

Alternatively, the entire support structure 11 may adjust the distance between the cover plate 111 and the base plate 113, or may adjust the length of the connecting rod 112, acting as a compression for the damper 20. Because the damper 20 may have different pressure-bearing capacities due to stress, heat, and the like during the process of manufacturing the damper 20, when the damper 20 is disposed between the cover plate 111 and the bottom plate 113, the tightness between the cover plate 111 and the bottom plate 113 can be changed according to the pressure-bearing capacity of various dampers 20, and the required pre-tightening force, reliability, and strength between the damper 20 and the mounting structure 10 are finally achieved.

Optionally, the mounting structure 10 further comprises: a second liquid collection structure 14.

The second liquid collecting structure 14 is detachably connected with one side of the bottom plate 113 far away from the cover plate 111.

In this embodiment, since the mounting structure 10 is installed below the tower flange 2, the present application provides a second liquid collecting structure 14, which is connected to the bottom plate 113 of the supporting structure 11, and at this time, can play a role of holding the damping liquid that may leak in the damper 20, so as to prevent the damping liquid from further leaking to the inside of the tower.
