The utility model discloses can effectively solve the problem of aerogenerator oil leak.

Description

Structure is retrieved to aerogenerator oil leak

Technical Field

The utility model belongs to the technical field of aerogenerator's technique and specifically relates to indicate an aerogenerator oil leak recovery structure.

Background

The wind driven generator bearing adopts an oil lubrication structure, because the internal temperature of the motor is higher, the internal air temperature is up to 90 ℃ when the generator runs at full speed, the lubricating oil for running at full speed is heated to about 55 ℃, the viscosity becomes very low, the permeability is very strong, the labyrinth structure is adopted for sealing the lubricating oil of the generator, the wind driven generator has a 7-degree inclination angle when being actually installed, the shaking condition can exist in the actual running process, the oil seepage phenomenon easily occurs in the generator, the leaked lubricating oil is accumulated and pressed in the generator for a long time, the adverse effect can be caused to the internal parts of the generator, the lubricating oil leaks into the cabin, the cleanness and tidiness in the cabin are influenced, and the problems of a slide way and the like of field maintenance personnel are easily caused. In the prior art, a hole is formed in a generator housing, so that leaked lubricating oil inside the generator housing is led to the outside of the generator housing, and an oil pipe is mounted on the generator housing, so that the leaked lubricating oil is led to a waste oil box inside a cabin. Because the cabin is connected with the generator shell through the bolts, during actual operation, the vibration frequency of the generator shell is deviated from that of the cabin, so that the oil pipe joint connecting the cabin and the generator shell is easy to loosen to cause oil leakage, and the oil pipe is arranged outside the cabin, so that the replacement and maintenance are very difficult. Meanwhile, as the oil pipe is positioned outside the engine room, in the arctic weather in the north, the lubricating oil flows into the oil pipe, the viscosity of the oil becomes high after the oil temperature is reduced, the oil pipe is easy to block, the integral structure is invalid, and the oil pipe and the joint are easy to corrode when the marine engine oil is used on the sea.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a aerogenerator oil leak recovery structure, can effectively solve the problem of aerogenerator oil leak.

In order to achieve the above object, the present invention provides a technical solution: the utility model provides a aerogenerator leaks oil and retrieves structure, processing has two first through-holes on aerogenerator shell and aerogenerator's cabin elbow matched with flange face, and these two first through-holes are deepened respectively to the both sides of generator shell bottom inner wall strengthening rib, the minimum position of generator shell internal cavity promptly, the corresponding processing of cabin elbow and two first through-hole relevant position departments has two second through-holes, just the second through-hole is linked together with corresponding first through-hole respectively, and the lubricating oil of aerogenerator seepage is led inside the cabin elbow through first through-hole, second through-hole to collect through the inside waste oil collection box of cabin elbow.

Furthermore, an O-shaped sealing ring is arranged between the first through hole and the corresponding second through hole.

Compared with the prior art, the utility model, have following advantage and beneficial effect:

the utility model discloses can make the lubricating oil of generator inside seepage gather after its generator shell inner wall minimum point position, directly introduce the waste oil collection box in the cabin elbow through the first through-hole of processing on the generator shell wall and the second through-hole on the cabin elbow, make the oil leakage can obtain effectual recovery, can not cause secondary pollution, and need not install any oil pipe joint, the structure is more reliable, also need not later maintenance; meanwhile, when the generator runs at full capacity, the temperature in the generator cavity can heat and preserve leaked lubricating oil, so that the flowability of the lubricating oil is increased, and the oil way cannot be blocked.

Detailed Description

The present invention will be further described with reference to the following specific embodiments.

As shown in fig. 1 and 2, in the oil leakage recovery structure of the wind power generator according to the embodiment, the outer shell 1 of the wind power generator is matched with the cabin elbow 2 of the wind power generator in a stop-and-go manner and is directly fixed and installed by bolts, the axis of the wind power generator forms an elevation angle of 7 degrees with the horizontal plane in actual operation, wherein two diameters are processed on the flange surface of the outer shell 1 of the wind power generator matched with the cabin elbow 2

The two first through holes 101 respectively penetrate into two sides of the inner wall reinforcing rib at the bottom of the generator shell 1, namely the lowest point position of the inner cavity of the generator shell 1, the cabin elbow 2 and the two second through holes 101A through hole 101 is correspondingly processed with two diameters at corresponding positions

When oil leaks in the generator bearing unit 3, leaked lubricating oil flows to two sides of the reinforcing rib on the inner wall of the bottom of the generator shell 1, and the two pieces of lubricating oil in the area are respectively led to the inside of the cabin elbow 2 through the first through hole 101 and the second through hole 201 and collected through a waste oil collecting box in the cabin elbow 2; simultaneously, counter bores are respectively processed at the two first through holes 101, so that the O-shaped sealing rings 4 are arranged between the first through holes 101 and the corresponding second through holes 201, and the sealing performance of the whole leaked oil recovery structure is ensured.

The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that all the changes made according to the shape and principle of the present invention should be covered within the protection scope of the present invention.
