Description
Technical Field
The utility model relates to the technical field of wind power gearboxes, in particular to a liquid level observation structure.
Background
The wind power gearbox is an important part of a wind generating set, and has the main function of transmitting power generated by a wind wheel under the action of wind power to a generator so as to convert wind energy into electric energy. Because wind generating set installs in the wind gap department of remote places such as mountain, wilderness, beach generally to install in the high altitude of several tens meters, the maintenance is extremely difficult, in order to improve wind-powered electricity generation gear box's stability and reliability, generally adds lubricating oil system in the wind-powered electricity generation gear box in the trade, lubricating oil system can reduce friction and wearing and tearing between gear and the bearing, and plays effects such as cooling, cleanness, anticorrosive, has important meaning to the maintenance of wind-powered electricity generation gear box. Because the wind power gear box is limited in internal structure and narrow in space, and the quantity of lubricating oil in the box body is insufficient, a secondary oil tank for storing lubricating oil is generally required to be arranged at the bottom of the box body, and the secondary oil tank can timely supplement the quantity of lubricating oil to the box body through a circulating pipeline between the secondary oil tank and the wind power gear box.
At present, in order to realize monitoring the liquid level of lubricating oil in a wind power gear box, chinese patent CN205533025U discloses a wind power generator set and a speed-increasing gear box thereof, wherein two liquid levels are respectively and directly installed on the wind power gear box and a secondary oil tank so as to realize detection of the highest liquid level and the lowest liquid level, however, the following problems exist in the prior art:
because wind-powered electricity generation gear box and bellytank are the components of a whole that can function independently setting, and have a section distance between wind-powered electricity generation gear box and the bellytank, and the level gauge is located wind-powered electricity generation gear box and bellytank, so when the lubrication oil level is between wind-powered electricity generation gear box and bellytank, the staff can only observe that the lubrication oil level is less than the range of wind-powered electricity generation gear box level gauge, and is higher than the range of bellytank level gauge, and can't observe specific lubrication oil level. If the staff inspects wind-powered electricity generation gear box, the lubricating oil liquid level just is slightly higher than the range upper limit of the level gauge of bellytank, the staff is easy to mistake and think that the wind-powered electricity generation gear box is not needed to add oil to the wind-powered electricity generation gear box again in a short time, but because wind generating set is located remote places such as mountain, wilderness, beach, the staff goes to the wind-powered electricity generation gear box again and adds oil very inconvenient and tired, simultaneously, reduces work efficiency.
Disclosure of Invention
The utility model provides a liquid level observation structure which can solve the problem that in the prior art, the liquid level of lubricating oil between a wind power gear box and a secondary oil tank is difficult to observe.
The application provides the following technical scheme:
