Wind power generation is a renewable energy source that plays an important role in the modern energy field. In a wind power plant, a wind power generator set is the core equipment responsible for converting wind energy into electrical energy. However, during the storage of the manufacturing plant and the wind power plant, the wind power generator set needs to periodically rotate the transmission chain to prevent the problems of indentation, rust and the like of rotating parts such as gears, bearings and the like. In order to ensure proper operation of the drive chain, it is necessary to provide a lubrication system for lubricating the drive chain during rotation of the drive chain to avoid losses and malfunctions caused by dry friction between the rotating parts.

Detailed Description

The present utility model will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments are shown.

As shown in fig. 1, this embodiment discloses a lubrication tool 100, which includes: the pipeline main circuit 1 comprises a first pipe orifice 11 and a second pipe orifice 12, wherein the first pipe orifice 11 is used for being connected with an oil outlet 41 of the transmission chain 4, and the second pipe orifice 12 is used for being connected with an oil inlet 42 of the transmission chain 4; the pump 31, the pump 31 is connected with the pipeline main way 1 and is used for conveying lubricating oil in the pipeline main way 1, and the flow path of the lubricating oil is a transmission chain 4, an oil outlet 41 of the transmission chain 4, a first pipe orifice 11, the pipeline main way 1, a second pipe orifice 12, an oil inlet 42 of the transmission chain 4 and the transmission chain 4 in sequence.

Specifically, a gear pump, which is a commonly used lubricating oil pump 31 suitable for transporting high-viscosity lubricating oil and has good stability and durability, may be used as the pump 31 in the lubrication tool 100. The lubricating oil is sucked from an oil outlet 41 of the transmission chain 4 through rotation of the gears and is conveyed to an oil inlet 42 of the transmission chain 4 through the pipeline main path 1. The pipeline main path 1 of the lubrication tool 100 can adopt a corrosion-resistant and high-temperature-resistant stainless steel pipeline, so that smooth flow of lubricating oil is ensured, and better performance can be maintained under different working conditions.

In the embodiment, the lubrication tool 100 is connected with the oil outlet 41 and the oil inlet 42 of the transmission chain 4 by adopting the pipeline main circuit 1, so that lubricating oil can conveniently flow out from the outlet of the transmission chain 4 and enter the inlet of the transmission chain 4 through the pipeline main circuit 1, lubrication of the transmission chain 4 is realized, lubrication is not required to be performed after the configuration of cabin components related to the transmission chain 4 is complete, and time difference is avoided; the pump 31 is connected with the pipeline main circuit 1, and can automatically convey lubricating oil to the oil inlet 42 of the transmission chain 4, so that continuous lubrication of the transmission chain 4 is realized, and reasonable lubricating oil supply can be realized according to the service condition and lubrication requirement of the transmission chain 4 through automatic control of the pump 31, so that the transmission chain 4 is ensured to be sufficiently lubricated in the storage period process.

As shown in fig. 1, the lubrication tool 100 further includes a filter mechanism 2, and the filter mechanism 2 includes: a first filter part 21 and a second filter part 22, both the first filter part 21 and the second filter part 22 being provided on the pipe main 1; the pipeline branch 23, the pipeline branch 23 is communicated with the pipeline main path 1 and is connected with the first filtering part 21 in parallel, the pipeline branch 23 is provided with a first one-way valve 231, and the first one-way valve 231 is used for controlling lubricating oil in the pipeline branch 23 to flow from upstream to downstream only.

Specifically, upstream and downstream are concepts of relative positions, upstream referring to a position located above a flow direction in the lubrication oil transfer, and downstream referring to a position located below the flow direction in the lubrication oil transfer, and a flow direction L of the lubrication oil is shown in fig. 1.

In the present embodiment, the filter mechanism 2 provides higher reliability and automation safeguards, and under normal conditions, the lubricating oil will pass through the first filter portion 21 and the second filter portion 22 in order, so that effective filtration treatment is performed, and at the same time, the pipe branch 23 does not circulate, i.e., the lubricating oil will not flow to the second filter portion 22. However, when the first filter portion 21 is clogged, the flow of the lubricating oil on the pipe main passage 1 is hindered, resulting in an increase in pressure of the pipe branch passage 23, and in this case, the first check valve 231 senses the increase in pressure, and the valve 33 is opened, so that the lubricating oil can bypass the first filter portion 21 and flow from the pipe branch passage 23 to the second filter portion 22, and thus, even if the first filter portion 21 is clogged, the lubricating oil can smoothly flow to the second filter portion 22, ensuring that the supply of the lubricating oil is not affected. This safeguard ensures a continuous supply of lubricating oil in the filter mechanism 2, ensuring that the drive train 4 is adequately lubricated even in the event of an abnormality in which the first filter portion 21 is clogged. Through the design, the lubrication tool 100 is more reliable in the operation process, the risks of insufficient lubrication and damage to the transmission chain 4 caused by blockage are greatly reduced, and the stability and reliability of the wind generating set are further improved.

Specifically, the first filter portion 21 and the second filter portion 22 adopt cartridge filters, and the filter accuracy of the cartridges is selectable according to actual demands. When the fine filtration of the first filter portion 21 is blocked, it means that there are more impurities in the lubricating oil, and the impurities in the lubricating oil flowing through the pipe branch 23 are relatively more, if the second filter portion 22 adopts the filtration with the same precision or higher precision, the second filter portion 22 is blocked in a short time, which may cause interruption of the supply of the lubricating oil, reduce the efficiency of the lubrication fixture 100, and possibly cause damage to the transmission chain 4. By setting the second filter portion 22 to coarse filtration, it can intercept larger impurities, and when the first filter portion 21 is blocked, the second filter portion 22 can still continue to provide a part of the filtration effect, ensuring the supply of lubricating oil, reducing the possibility of simultaneous blocking of the two filter portions, and improving the reliability and service life of the filter mechanism 2. Of course, in other alternative embodiments, the filtering precision of the two filtering portions may also be set to be the same.

The indicating means may employ a differential pressure indicator which determines the degree of clogging of the filter by measuring the differential pressure of the lubricating oil between the inlet and outlet of the filter, and when the filter is clogged, the resistance of the lubricating oil passing through the filter increases, resulting in an increase in the differential pressure, thereby causing the indicator to display clogging information. The filter indicator 24 may be configured as a visual display device, such as a pointer or a liquid crystal display, to allow the operator to intuitively understand the operating state of the filter.
