Horizontal axis semi-integrated type ocean current energy generator set

Abstract

The invention discloses a horizontal axis semi-integrated type ocean current energy generator set. The horizontal axis semi-integrated type ocean current energy generator set comprises a propeller hubmodule, a main shaft gear case integrated module and a motor module which are sequentially arranged. The main shaft gear case integrated module comprises a main shaft, a power output shaft and a shell. A main shaft front end bearing pedestal and a main shaft rear end bearing pedestal are arranged between the two ends of the main shaft and the shell correspondingly. The main shaft front end bearing pedestal is located on the side, facing the propeller hub module, of the main shaft rear end bearing pedestal. A main shaft seal preventing seawater in the outside world from entering the main shaftgear case integrated module is arranged between the main shaft front end bearing pedestal and the main shaft. A propeller hub flange is arranged at the end, facing the main shaft, of the propeller hub module. A rapid replacement seal structure used for rapidly overhauling and replacing a seal ring of the main shaft seal is arranged between the main shaft and the propeller hub flange. The motor module comprises a motor input shaft. An elastic coupling module is arranged between the power output shaft and the motor input shaft.

Description

technical field [0001] The invention relates to a generating set, in particular to a horizontal axis semi-integrated ocean current energy generating set. Background technique [0002] Energy shortage is a common problem faced by all countries in the world today, and the development of renewable energy is urgent. In the field of renewable energy, ocean current energy is a kind of clean and renewable energy. my country has abundant ocean current energy reserves, and its development and utilization potential is huge. Ocean current energy has the advantages of high energy density and strong predictability. The horizontal axis ocean current energy generator is a device that converts ocean current energy into electrical energy. Most of the existing horizontal-axis current energy generators are unidirectional power generation, which is technically relatively easy. The unidirectional power generation system is a fixed-pitch device or a variable-pitch device. However, many offshore...

AI Technical Summary

Problems solved by technology

[0004] In the ocean operating environment, it is necessary to face the problem of entanglement by suspended fishing nets. If the ocean current energy generator set has no self-protection measures, if it is entangled by the fishing net, the unit will be stuck, unable to operate normally, and even cause the entire unit to be destroyed.

In addition, unlike the atmospheric environment, marine attachments must also be considered. The growth of bacteria, algae, and biological larvae will cause accelerated corrosion and damage to leaves.

The blades are often made of composite materials. After long-term immersion in seawater, the strength will decrease, and the blades will also break during use, causing the unit to be subjected to load impact; it will cause damage to bearings and gears

[0005] Existing ocean current energy generating sets all adopt an integrated overall layout structure, such as a horizontal axis ocean current energy generating set and its gearbox disclosed in Chinese patent application with publication number CN106894939A. Although it can meet the requirements for use, there are still Inconvenient maintenance and other problems, especially in the environment of marine operation, cause great difficulties for maintenance
