Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine maintenance equipment, and in particular to a wind turbine maintenance tooling. Background Technology

[0002] A wind turbine is a renewable energy device that converts wind energy into electricity. Its core principle is to capture wind kinetic energy through a rotor, causing the blades to rotate and drive a generator via a transmission system. It mainly includes a rotor (including blades), tower, nacelle (containing the gearbox and generator), steering mechanism, and control system. Horizontal axis models are the mainstream, but vertical axis designs are also becoming increasingly common. Utilizing the law of electromagnetic induction, an electric current is generated when the rotor cuts magnetic lines of force in a magnetic field. Some models employ variable speed constant frequency technology to optimize power generation efficiency at different wind speeds. These turbines are widely used in onshore and offshore wind farms, especially suitable for areas with abundant wind resources. Small units can supply electricity to homes, while large clusters are connected to the grid to provide large-scale clean energy. This technology features zero fuel cost and zero pollution emissions, making it an important way to achieve the "dual carbon" goal (carbon reduction and emission reduction). With the development of materials science and the application of intelligent control systems, modern wind turbines continue to improve in efficiency, reliability, and adaptability.

[0003] A utility model patent with patent publication number CN220470125U provides a wind turbine maintenance fixture. It utilizes a lifting mechanism and a first thread, allowing workers to move the lifting rod by rotating the threaded rod through a connection between the first thread and the lifting rod. This allows for height adjustment by controlling the motor. Furthermore, controlling a first hydraulic rod brings two clamping rods closer together. A clamping mechanism and a second thread allow two second limiting blocks to move via a rotating screw. Because the internal threads of the two second limiting blocks are opposite, they can move simultaneously or in opposite directions, thus clamping the parts. A second motor is fixedly installed on one side of the screw, extending through it, and its output is fixedly connected to the screw. While this method solves the problem of fixing the maintenance workbench, it also presents challenges. Because the workbench does not neatly store the disassembled parts of the wind turbine, it increases the difficulty of repositioning the parts after maintenance and makes effective placement of the parts impossible.

[0004] Therefore, it is necessary to provide a wind turbine maintenance tool to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a wind turbine maintenance tool to solve the problem that although the method in the background technology solves the problem of fixing the maintenance workbench, it also has the following problems: since the above workbench does not properly store the parts after the wind turbine is disassembled, it increases the difficulty of resetting the workpiece after the maintenance work is completed, and it is impossible to effectively place the parts.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A maintenance tool for a wind turbine includes: a workbench, an operating table, a placement component, and a storage box; An operating table and a storage box are arranged sequentially at intervals on the right side of the workbench. Placement components are installed on both sides of the top of the operating table. A generator component is placed inside the workbench. The workbench serves as the main support structure for maintenance. Placement components and corresponding cleaning structures are installed above the operating table.

[0007] In one embodiment, the operating platform is a base plate structure, comprising a power box, a rotating shaft, connecting rods, a positioning plate, positioning holes, a liquid inlet pipe, a nozzle, and a waste liquid tank. A rotating shaft is mounted on the top of the power box via a coupling. Connecting rods are mounted on both sides of the top of the rotating shaft. A positioning plate is mounted on the extended end of each connecting rod. The positioning plate is a tubular structure, with positioning holes arranged in a circular array on its top surface. Each positioning plate is inserted into a placement component. A waste liquid tank is mounted on the right side of the operating platform, and a nozzle is positioned directly above the waste liquid tank. The other end of the nozzle is connected to an external liquid supply tank via a liquid inlet pipe, which delivers cleaning fluid.

[0008] In one embodiment, the placement component comprises a box body, a drain tank, a fixing plate, fixing pins, a drain pipe, a filter plate, and a handle. The box body is a cylindrical structure with an open top surface. A drain tank, which is connected to the bottom of the box body, is installed. The drain tank is an inverted frustum-shaped structure. A drain pipe is installed at the bottom of the drain tank, and a control valve is installed on the drain pipe. A fixing plate is fitted around the outside of the drain pipe. Fixing pins are installed in a circular array at the bottom of the fixing plate. Handles are installed on both sides of the top of the box body. A filter plate is installed at the internal connection between the box body and the drain tank.

[0009] In one embodiment, the inner top surface of the workbench is a placement platform, and a channel is provided around the placement platform, with a guide pipe installed at the bottom of one side of the channel.

[0010] In one embodiment, the interior of the storage box is divided into several placement areas by partitions, so that each placement area contains corresponding parts, making it more convenient and faster to retrieve the parts when resetting.

[0011] The beneficial effects of this utility model are as follows: This utility model, by installing the aforementioned components at intervals on the right side of the workbench, allows for the separate cleaning and placement of generator parts during disassembly and maintenance, making subsequent resetting more convenient and reducing the difficulty of the resetting operation. The partition divides the workbench into several placement areas, with each area corresponding to the placement of parts, making it more convenient and faster to retrieve parts during resetting, preventing the problems of mis-picking or loss.

[0012] This utility model allows manual handling to move the box body above the positioning plate and towards it until the fixing pin is inserted into the positioning hole, causing the fixing plate to abut against the positioning plate and completing the installation connection. Disassembled parts are then manually placed onto the top surface of the filter plate, allowing waste liquid to flow into the drain pipe below. After a batch of parts is placed, the power unit is activated, driving the rotating shaft to rotate the box full of parts once, moving it above the waste liquid tank. At this point, the box without parts is positioned near the workbench, continuing to receive parts. By activating the inlet pipe, cleaning fluid is sprayed through the nozzle to clean the parts inside the box. The valve of the drain pipe is opened, allowing waste liquid to enter the waste liquid tank for collection. This design allows for simultaneous collection and cleaning, improving the efficiency of parts processing. It also cleans disassembled parts, integrating multiple functions into one unit, reducing space requirements, and significantly improving functionality, making it more suitable for practical use.

[0016] like Figures 1-2 As shown, the present invention provides a wind turbine maintenance tool, including: a workbench 1, an operating table 2, a placement component 3, and a storage box 4; like Figure 1 As shown, an operating table 2 and a storage box 4 are arranged sequentially at intervals on the right side of the workbench 1. Placement components 3 are installed on both sides of the top of the operating table 2. Generator components are placed inside the workbench 1. The workbench 1 is the main support structure for maintenance. Placement components 3 and corresponding cleaning structures are installed above the operating table 2. By installing the above-mentioned components at intervals on the right side of the workbench 1, the generator parts inside the workbench 1 can be separated, cleaned, and placed separately when disassembling and maintaining them. This makes subsequent resetting more convenient and reduces the difficulty of resetting operations.

[0017] Preferably, in one embodiment, such as Figures 2-3 As shown, the operating platform 2 is a base plate structure. The operating platform 2 consists of a power box 21, a rotating shaft 22, a connecting rod 23, a positioning plate 24, a positioning hole 25, a liquid inlet pipe 26, a nozzle 27, and a waste liquid tank 28. The top of the power box 21 is equipped with a rotating shaft 22 via a coupling. Both sides of the top of the rotating shaft 22 are equipped with connecting rods 23. The extension end of the connecting rod 23 is equipped with a positioning plate 24. The positioning plate 24 is a tubular structure. The top surface of the positioning plate 24 has positioning holes 25 arranged in a ring array. Each positioning plate 24 is inserted and connected to the placement component 3. The right side of the operating platform 2 is equipped with a waste liquid tank 28. A nozzle 27 is located directly above the waste liquid tank 28. The other end of the nozzle 27 is connected to an external liquid supply tank via a liquid inlet pipe 26. The liquid inlet pipe 26 delivers cleaning fluid.

[0018] Preferably, in one embodiment, such as Figures 2-4As shown, the placement component 3 consists of a box body 31, a drain tank 32, a fixing plate 33, fixing pins 34, a drain pipe 35, a filter plate 36, and a handle 37. The box body 31 is a cylindrical structure with an open top surface. The drain tank 32, which is connected to the bottom of the box body 31, is an inverted frustum-shaped structure. A drain pipe 35 is installed at the bottom of the drain tank 32, and a control valve is installed on the drain pipe 35. A fixing plate 33 is fitted around the outside of the drain pipe 35. Fixing pins 34 are installed in a circular array at the bottom of the fixing plate 33. Handles 37 are installed on both sides of the top of the box body 31. A filter plate 36 is installed at the internal connection between the box body 31 and the drain tank 32. During operation, the box body 31 is moved above the positioning plate 24 by manually holding the handles 37 and is moved toward the positioning plate 24 until the fixing pins 34 are inserted into the positioning holes 2. 5. Inside, the fixing plate 33 and the positioning plate 24 abut against each other to complete the installation connection. The disassembled parts are manually placed on the top surface of the filter plate 36, allowing the waste liquid to flow into the drain pipe 35 below. After a batch of parts is placed, the power box 21 is started to drive the rotating shaft 22 to rotate, causing the box 31 filled with parts to rotate one revolution and move above the waste liquid tank 28. At this time, the box 31 without parts is in a position close to the workbench 1, and continues to receive parts. By starting the liquid inlet pipe 26, the cleaning liquid is sprayed out through the nozzle 27 to clean the parts in the box 31. The valve of the drain pipe 35 is opened to allow the waste liquid to enter the waste liquid tank 28 for collection. Through the above component settings, collection and cleaning can be carried out simultaneously, improving the processing efficiency of parts. At the same time, the disassembled parts are cleaned, integrating multiple functions into one, reducing the footprint, and significantly improving the functional effect, making it more in line with actual use.

[0019] Preferably, in one embodiment, such as Figure 1 As shown, the inner top surface of the workbench 1 is a placement platform 11, and a channel 12 is provided around the placement platform 11. A guide pipe 13 is installed at the bottom of one side of the channel 12. Through the above structural arrangement, the waste gas and oil generated during disassembly can be collected and treated.

[0020] Preferably, in one embodiment, such as Figure 1 As shown, the interior of the storage box 4 is divided into several placement areas by partitions 41, so that each placement area is used to place the parts. This makes it more convenient and faster to retrieve the parts during resetting, and prevents the problem of taking the wrong parts or losing them.

[0021] Working principle of this utility model: During operation, the box 31 is moved above the positioning plate 24 by hand using handle 37, and then moved toward the positioning plate 24 until the fixing pin 34 is inserted into the positioning hole 25, so that the fixing plate 33 and the positioning plate 24 abut against each other, completing the installation connection between the two. The disassembled parts are placed on the top surface of the filter plate 36 by hand, so that the waste liquid flows into the drain pipe 35 below. After a batch of parts is placed, the power box 21 is started to drive the rotating shaft 22 to rotate, so that the box 31 filled with parts rotates one revolution and moves above the waste liquid tank 28. At this time, the box 31 without parts is in a position close to the workbench 1, and continues to receive parts. By starting the liquid inlet pipe 26, the cleaning liquid is sprayed out through the nozzle 27 to clean the parts in the box 31. The valve of the drain pipe 35 is opened to allow the waste liquid to enter the waste liquid tank 28 for collection.

[0022] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model.
