Embodiment 1

[0033] figure 1 It is a schematic structural view showing a maintenance device for offshore wind power generating sets according to Embodiment 1 of the present invention.

[0034] refer to figure 1 , since the key parts of offshore wind turbines need to be cleaned and oil changed regularly, and the operation and maintenance time at sea is limited, in order to reduce the operation and maintenance time of offshore wind turbines and improve the availability of offshore wind turbines, oil circuits can be used Regularly clean and change the oil of the key parts of the offshore wind power generating set. Specifically, the maintenance device for the offshore wind generating set includes an oil inlet branch 100 and an oil return branch 200. Liquid and the grease used when changing the oil of the parts are provided to the parts through the oil inlet branch 100, and the waste cleaning fluid after cleaning the parts can be recycled to the designated oil tank 300 through the oil return b...

Embodiment 2

[0041] figure 2 It is a schematic structural view showing a maintenance device for an offshore wind power generating set according to Embodiment 2 of the present invention. The maintenance unit contains figure 1 All the functional units of the maintenance device shown, and on the basis of it, it has been improved, and the improvements are as follows:

[0042] refer to figure 2 , There may be impurities in the grease or cleaning fluid, such as metal particles or debris, etc. In order to prevent the above impurities from entering the first vane pump 102 and causing the first vane pump 102 to be damaged, the The hydraulic oil of 100 is first filtered through a filter to remove the above-mentioned impurities in the grease or cleaning fluid. Specifically, a primary filter 101 is provided on the oil inlet side of the first vane pump 102, wherein the primary filter 101 can be used It is made of a filter net of a predetermined material, and the mesh of the filter net can be set a...

Embodiment 3

[0057] Based on the same technical idea, image 3 It is a logical block diagram showing a maintenance system for offshore wind power generating sets according to Embodiment 3 of the present invention. refer to image 3 , the maintenance system includes the maintenance device for the offshore wind power generating set described in the first or second embodiment above and the control cabinet 500, wherein the control cabinet 500 can be used to control the corresponding functions of the above maintenance device.

[0058] Such as Figure 4 As shown, the control cabinet 500 includes one or more control branches 530 connected in parallel to the power grid, and each control branch 530 includes a motor M, a thermal relay FR, an AC relay KM and a branch circuit breaker FD connected in sequence, Among them, the electric motor M can be used to provide power for the oil change operation of the equipment to be maintained. The thermal relay FR can be used to detect the heating of the moto...

Abstract

The embodiment of the invention provides a maintenance device and system and maintaining ship for an offshore wind generating set. The maintenance device comprises an oil inlet branch (100), an oil return branch (200), an electromagnetic directional valve (109) and two paths of oil pipes (400), and one end of each oil pipe (400) is connected with equipment to be maintained. A first vane pump (102), a first check valve (103) and a booster pump (106) are sequentially arranged on the oil inlet branch (100) in the oil inlet direction. The guide direction of the first check valve (103) is the oil inlet flowing direction. An oil outlet of the oil inlet branch (100), an oil inlet of the oil return branch (200) and the other ends of the two paths of oil pipes (400) are connected with the electromagnetic directional valve (109). Through the adoption of the maintenance device and system and maintaining ship for the offshore wind generating set, the operation and maintenance time of the offshore wind generating set can be shortened, and the power generation efficiency of the offshore wind generating set can be improved.

Description

technical field [0001] The invention relates to wind power generation technology, in particular to a maintenance device, system and maintenance ship for offshore wind power generating sets. Background technique [0002] Offshore wind power, as the main form of wind power generation in the future, has attracted much attention. Due to the stringent requirements of marine environmental protection, the activities of offshore wind farms have become very cautious, and the operation and maintenance of offshore wind turbines has become an important issue that needs to be solved urgently. [0003] The key components of offshore wind turbines need to be cleaned and oiled regularly. Usually, the key components are cleaned and oiled manually. Specifically, the operation of offshore wind turbines can be stopped, and the operation and maintenance The engine room of the generator set, and use the cleaning fluid to clean the key parts. After cleaning, inject new grease or lubricating oil in...
