Problems solved by technology

At the same time, as people pay more and more attention to the maintenance of wind power devices, and as the use time increases, the lubrication problem of the oil change target box of wind power devices becomes prominent, which will affect its normal use and cause a certain degree of safety damage. threaten
[0003] In advanced countries in Europe and the United States, wind power has been used for decades, the industry chain is mature, and wind power service is a mature industry. In the United States, several professional service companies have been listed. An important business of Weiwei has been fully mechanized. However, the professional oil change equipment originated in the United States and Germany is expensive (about 2.5 million RMB per set), bulky and expensive to use, which restricts its promotion and use in China.
Moreover, in China, the traditional oil change method has low efficiency, slow oil change work, and unsatisfactory cleaning work, all of which are potential factors affecting the performance of wind power installations

Embodiment 1

[0029] see figure 1 , the wind turbine assembly line oil change system includes high-altitude equipment cabin (22), waste oil barrels (1.1, 1.2, ..., 1. k ), cleaning oil drums (2.1, 2.2, ..., 2. m ) and new barrels (3.1, 3.2, ..., 3. n ), characterized in that: a hoist (19) is installed next to the oil change target box in the high-altitude equipment cabin (22), and the hoist (19) is connected to the lower end of a hanging hook rope (15) A hook (14); the waste oil barrel (1.1, 1.2, ..., 1. k ), cleaning oil drums (2.1, 2.2, ..., 2. m ) and new barrels (3.1, 3.2, ..., 3. n) top has a rope connected between the hook ring I (12) and the hook ring II (13) to be hung on the hook (14), and two safety rings I ( 8), safety ring II (10) and safety ring III (9), safety ring IV (11), safety wire rope I (16) and safety wire rope II (21) can respectively pass through four safety rings (8 . The safety cables (16, 21) are parallel to each other, and each has a tensioner (6, 7) to mak...

Embodiment 2

[0031] This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0032] The waste oil barrels (1.1, 1.2, ..., 1.k) are used to specially accommodate the waste oil in the oil change target box, according to the system scale k The size of the can vary; the cleaning oil barrel (2.1, 2.2, ..., 2. m ) is used to specially install the cleaning oil for cleaning the target box of oil change, according to the system scale n The size of the can vary; the new barrels (3.1, 3.2, ..., 3. n ) is used to specially install the new oil for updating the oil change target box, according to the system scale m The size can be changed; the safety wire rope I (16) and the safety wire rope II (21) are installed in parallel between the high-altitude equipment cabin (22) and the ground, and have a certain pulling force to ensure the safety during the oil change process, In the event of an accident, the oil drum breaks away from the hook, and the falling positi...

Embodiment 3

[0034] This wind turbine assembly line type oil change method adopts the above-mentioned system for oil change, and is characterized in that it includes the following operation process: waste oil extraction process, waste oil extraction process ends and cleaning process starts alternate process, cleaning process, cleaning process ends and new delivery process Alternate flow of oil process start and delivery of new oil flow.

[0035] see figure 2 , Waste oil extraction process: First, hang the empty waste oil barrel (1.1) with a hook, then turn on the pump unit to work normally and pump the waste oil in the oil change target box to the waste oil barrel (1.1), where it is extracted Use the hook to hang up the empty waste oil barrel (1.2) while the waste oil is being used. Next, the waste oil barrel (1.1) is full and the waste oil barrel (1.2) reaches the working position, and the pump unit is turned on to work normally to pump the waste oil in the oil change target box to the ...

Abstract

The invention relates to a flow line type oil changing system and method for a wind power generation set. The system comprises a waste oil drum, a cleaning oil drum, a new oil drum, a steel cable fixer, a tensioner, a safety ring, a lifting hook ring, a lifting hook, a hook rope, a safety steel cable, an hoister and a tower. The method includes: waste oil extraction, alternating between waste oil extraction and cleaning, cleaning, alternating between cleaning and new oil conveying, and new oil conveying. The oil changing system and method has the advantages that by the system and method, oil changing can be performed conveniently, and a large amount of oil changing time and labor can be saved; the safety steel cable is used, so that safe oil changing is achieved; the system is practical in structure and high in safety; the method is novel in operation, low in difficulty, high in efficiency, suitable for oil changing of various high-altitude mechanical devices, and especially suitable for occasions that the devices requiring oil changing are located at relatively-high positions.

Description

technical field [0001] The invention relates to an oil change system and method for a wind turbine, in particular to an oil change system and method for a wind turbine using an assembly line working mode and having high safety. Background technique [0002] In recent years, with the continuous progress of society, the continuous innovation of science and technology. my country's domestic wind power construction has advanced by leaps and bounds in the past few years. The total installed capacity is about to exceed 60,000 units by the end of 2013, and the current annual average installed capacity is 5-6,000 units, becoming the real world's largest wind power country. In the next 1-5 years, the maintenance of wind turbines in operation will soon form a modern high-tech service industry with huge capacity, among which the oil change work of the large-scale variable speed oil change target box is the most difficult. This service requires that hundreds of high-viscosity expired w...
