In the figure: the device comprises a shell A1, a main shaft A2, a large-pitch hinge 3, a shell B4, a main shaft B5, a small-pitch hinge 6, an inner shaft 7, a bearing disc 8, a bearing 9, a bottom shell 10 and water 11.

Detailed Description

The invention is explained in further detail below with reference to the figures and the specific embodiments.

As shown in fig. 1 to 4, a diving bearing protection structure comprises a housing a1, a main shaft a2, a large pitch twisted blade 3, a housing B4, a main shaft B5, a small pitch twisted blade 6, an inner shaft 7, a bearing disc 8, a bearing 9 and a bottom shell 10, wherein the large pitch twisted blade 3 is welded on the outer wall of the main shaft a2 and arranged equidistantly, the top end of the main shaft a2 is embedded in a through hole at the center position of the inner top end of the housing a1 and extends out of the housing a1 through the through hole, the housing B4 is welded on the bottom end of the housing a1 and extends into the housing a1, the small pitch twisted blade 6 is welded on the outer wall of the main shaft B5 and arranged equidistantly, the main shaft B5 is embedded in the center position of the housing B4, the inner shaft 7 is embedded from the top end of the main shaft B5 and penetrates through the bottom end of the housing B6866 to the outside through the main shaft B73729, the top end of the main shaft a2 is embedded in the bottom end of the inner shaft B4 of the bearing disc 367, the bearing 9 is embedded at the bottom end of the bearing disc 8, the inner ring of the bearing 9 is connected with the bottom end of the inner shaft 7, the bottom shell 10 is installed at the bottom of the bearing disc 8 through threads, the shell B4 is filled with water 11, and the horizontal plane is located 10cm-15cm below the top end of the bearing disc 8, so that the water 11 cannot enter the bearing 9 through the bearing disc 8.

The bottom of the shell A1 is drilled with through holes arranged at equal intervals.

The bearing disk 8 is inserted into the gap between the inner shaft 7 and the main shaft B5 from the bottom end of the outer shell B5, and water 11 does not seep out because a sealing gasket is arranged at the contact position of the bearing disk 8 and the outer shell B5.
