Problems solved by technology

Some manufacturers use a double-impeller structure to achieve yaw indirectly. Although it can accept the energy of two-way water flow, it increases the cost of impellers and blades.
Currently there is no overall centralized application solution

Abstract

The invention discloses a semi-direct drive type transmission chain for a tidal current energy unit and the tidal current energy unit comprising the same, and belongs to the field of tidal current energy unit equipment. The transmission chain comprises a hub, a gear box, a connecting cabin, a generator and a tail cabin which are connected in sequence, the hub and the gear box are connected througha main shaft, a motive seal is arranged at the joint between the hub and the gear box, wherein the gear box is a semi-direct drive type gear box; and a pitch changing mechanism is installed on the hub, and the pitch changing mechanism can achieve the pitch changing angle ranging from 0 degree to 270 degrees. According to the semi-direct drive type transmission chain for the tidal current energy generator set, the requirements of tidal current energy power generation are met, pitch changing is accurately controlled, so that accuracy and safety are ensured, the failure risk of the unit is effectively reduced and pitch changing is accurately controlled, so that safe and reliable operation of the unit is realized.

Description

technical field [0001] The invention relates to the field of tidal current energy unit equipment, in particular to a semi-direct drive type tidal current energy unit transmission chain and a tidal current energy unit comprising the same. Background technique [0002] my country has a vast sea area, and there is a huge amount of energy in the ocean, and tidal energy is one of them, which can be measured and predicted by current meters. The flow velocity drives the impeller to rotate, and the tidal current energy is converted into mechanical energy through the gearbox speed-increasing mechanism, and then converted into electrical energy through the generator. At present, the semi-direct drive structure has been quite tested and applied in the field of wind energy similar to tidal current energy. [0003] At present, for tidal energy generating units, most manufacturers use multiple small units to generate electricity in a centralized manner, which virtually increases the failu...
