Rolling bearing protection device and a suitable vertical axis tidal current energy generating device thereof

Abstract

The invention provides a rolling bearing protection device and a suitable vertical axis tidal current energy generating device thereof. The vertical axis tidal current energy generating device comprises a frame, a vertical axis hydro generator, a rolling bearing and the rolling bearing protection device. The vertical axis hydro generator comprises a main shaft arranged perpendicular to the horizontal plane, and one end of the main shaft is rotatably arranged at the bottom of the frame; the rolling bearing is arranged at one end of the main shaft in a sleeving mode; the rolling bearing protection device is arranged on the upper part of the rolling bearing; and the rolling bearing protection device comprises a first sealing protection device, a first water leakage protection cavity and a second sealing protection device which are sequentially arranged in the gravity direction, the first sealing protection device comprises one or more first sealing assemblies, the first water leakage protection cavity comprises a first water accumulation cabin and a first drainage hole, the first drainage hole is formed in the side wall of the first water accumulation cabin, and the second sealing protection device comprises one or more second sealing assemblies.

Description

technical field [0001] The invention belongs to the field of tidal current energy generation, in particular to a rolling bearing protection device and an applicable vertical axis tidal current energy generation device. Background technique [0002] Ocean energy (including tidal current energy, wave energy, temperature difference energy, salinity difference energy, ocean current energy, etc.) is a clean and pollution-free renewable energy with abundant reserves and wide distribution, which has excellent development prospects and value. Today's energy is increasingly scarce, the greenhouse effect is becoming more and more serious, and energy needs to be low-carbon. Therefore, clean energy such as wind energy and ocean energy is the development direction of future energy. But now these clean energy power generation equipment, in addition to the relatively mature utilization of wind energy, the utilization of ocean energy is still in its infancy, lacking general and mature equip...

Problems solved by technology

This not only fails to reduce the cost, but increases the use and maintenance cost of the bearing

However, none of the existing vertical-axis tidal current power generation devices can solve the sealing problem of rolling bearings after long-term use
