Description

Technical Field

[0001] This utility model relates to the field of wind turbine generators, specifically to a cleaning device for the base of a medium-speed permanent magnet water-cooled wind turbine generator. Background Technology

[0002] Medium-speed permanent magnet wind turbine stators come in two structures: water-cooled and air-cooled. As the power of the wind turbine increases, the need for efficient heat dissipation becomes more stringent, making water-cooled structures the primary structure for medium-speed permanent magnet wind turbine stators. The water channels in the turbine frame are a core component of the water-cooled stator unit. The cleanliness, unobstructed flow, and leak-free nature of these channels are crucial for effective water cooling. Therefore, during stator manufacturing, the water channels must be cleaned and inspected using technical means. Currently, the cleaning method involves directly connecting a flexible hose to a tap water line, inserting it into the interface of the generator frame, securing it securely, and then flushing with water.

[0003] Therefore, it is necessary to provide a new technical solution. Utility Model Content

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] This utility model provides a cleaning device for the base of a medium-speed permanent magnet water-cooled wind turbine generator, referenced. Figure 1 It includes a water tank 1, an inlet pipe 2, an inlet water pump 3, a stator base 4, an outlet water pipe 5, a water injection control valve 11, an outlet water control valve 21, a flow meter 22, an outlet water pump (not shown), an inlet flange 12, an outlet flange 23, and a cable tray 31.

[0028] The first end of the water inlet pipe 2 is connected to the lower part of the water tank 1, the second end of the water inlet pipe 2 is connected to the water inlet on the stator frame 4, the water pump 3 is installed on the water inlet pipe 2, and the water pump 3 pumps the water in the water tank 1 to the stator frame 4. The first end of the water outlet pipe 5 is connected to the water outlet of the stator frame 4, and the second end of the water outlet pipe 5 is connected to the top of the water tank 1.

[0029] The water injection control valve 11 is located at the second end of the water inlet pipe 2 near the stator frame 4. The water injection control valve 11 adjusts the water flow rate in the water inlet pipe 2. The water outlet control valve 21 is located at the first end of the water outlet pipe 5 near the stator frame 4. The water outlet control valve 21 adjusts the water flow rate in the water outlet pipe 5.

[0030] The flow meter 22 is installed at the outlet of the water control valve 21, and the flow meter 22 detects the water flow rate on the water outlet pipe 5 in real time.

[0031] The second end of the water outlet pipe 5 is provided with a filter screen (not shown), which filters out impurities after cleaning the stator base 4.

[0032] The water pump is installed on the water outlet pipe 5. The water pump pumps the water in the stator frame 4 to the water tank 1, thereby completing the recycling of the cleaning water. Alternatively, the top of the water tank 1 is lower than the height of the water outlet flange 23, so that the water in the stator frame 4 flows into the water tank 1 automatically by gravity, which can also achieve water recycling.

[0033] The inlet flange 12 and the outlet flange 23 are both connected and fixed to the stator base 4 by bolts. The second end of the inlet pipe 2 is connected to the water inlet of the stator base 4 through the inlet flange 12. The first end of the outlet pipe 5 is connected to the water outlet of the stator base 4 through the outlet flange 23.

[0034] The extension cord 31 is directly connected to the inlet water pump 3 and the outlet water pump to increase their power.

[0035] The working principle of this invention is as follows: the inlet pipe connects the outlet of the water tank and the inlet of the stator frame, and the outlet pipe connects the outlet of the stator frame and the inlet of the water tank, thereby realizing the recycling of water flow and improving water utilization. Simultaneously, water injection control valves and outlet control valves are installed on the inlet and outlet pipes to regulate the water flow rate. A flow meter continuously monitors the water flow rate in the outlet pipe, thus matching it to the size of the stator frame.

[0036] Furthermore, this invention not only enables water cleaning but also achieves acid washing, alkali washing, and filtration—relying on fluid media to function within the workpiece—through customized pipelines and equipment coatings. Moreover, this invention can be applied not only to wind power equipment such as direct-drive, medium-speed permanent magnet, high-speed permanent magnet, and doubly-fed systems, but also to other fields relying on fluid media, such as agricultural machinery.
