Description

Technical Field

[0001] This invention relates to the field of heat treatment technology for fan stators, specifically to a heat treatment device and method for fan stators. Background Technology

[0002] The wind turbine stator is an important component of a wind turbine generator set, typically consisting of a steel casing and a generator stator. During operation, the generator of a wind turbine generator set continuously receives kinetic energy from the wind and converts it into electrical energy. However, the instability and intermittency of wind energy often cause various problems to arise during the operation of wind turbine generator sets, one of which is generator stator failure. The stator winding is one of the most important parts of the generator, consisting of a series of coils. By changing the direction of the current in the coils, the generator can be made to rotate continuously when driven by wind energy, thereby converting wind energy into electrical energy.

[0003] Heat treatment of the fan stator is a crucial step in the manufacturing process. It improves the stator's mechanical properties and corrosion resistance. Heat treatment generally includes three stages: heating, holding, and cooling. Heating aims to bring the stator material to a certain temperature to alter its internal structure. Holding aims to maintain the stator material at a certain temperature for a period of time to allow for sufficient internal structural changes. Cooling aims to gradually cool the stator material down to fix its internal structure. After heat treatment, the stator needs to be cleaned and inspected to ensure it meets quality requirements.

[0004] After heat treatment, the stator needs to be cooled before use. In the existing technology, the cooling method for the fan stator is usually forced air cooling to carry away the heat generated on the outer wall of the fan stator. Although the air can continuously blow away the heat, it does not directly reduce the temperature of the outer wall of the fan stator during operation, which reduces the work efficiency of the workers in cooling the fan stator after heat treatment. Therefore, a heat treatment device and method for fan stator are proposed. Summary of the Invention

[0005] The purpose of this invention is to address the problem that although wind power can continuously blow out heat, it does not directly reduce the temperature generated on the outer wall of the fan stator during operation, thus increasing the work efficiency of workers in cooling the heat-treated fan stator. This application provides a heat treatment device and method for a fan stator, which can directly reduce the temperature generated on the outer wall of the fan stator, thereby improving the work efficiency of workers in cooling the heat-treated fan stator.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a heat treatment device and method for a fan stator, comprising a workbench, support plates installed on both sides of the top of the workbench, and an air collection box installed on the top of the support plates, and further comprising:

[0007] A rotating cooling mechanism is used to cool the inside of the air collection box, and the rotating cooling mechanism is located inside the air collection box;

[0008] The air-blowing and discharging mechanism is used to blow air and discharge cooling to the inside of the air collection box and the fan stator located below the inside of the air collection box. The air-blowing and discharging mechanism is located on the rotating cooling mechanism.

[0009] A rotating dust removal mechanism is used to remove dust from the surface of the fan stator. The rotating dust removal mechanism is located below the rotating cooling mechanism.

[0010] Preferably, the rotating cooling mechanism includes a servo motor mounted on the top of the outer wall of the air collection box, the output end of the servo motor is fixedly connected to a rotating tube, and the bottom of the rotating tube extends rotatably into the interior of the air collection box. A water pump is connected to the outer wall of the rotating tube, and a circulating water pipe is connected to one side of the water pump.

[0011] Preferably, the rotating tube has a storage chamber inside, which is filled with cooling water. The water pump is located below the storage chamber and is connected to the inside of the storage chamber. The top of the air collecting box has a rotating groove, and the rotating tube extends into the inside of the air collecting box through the rotating groove. The circulating water pipe is curved, and the end of the circulating water pipe away from the water pump is connected to the top of the outer wall of the rotating tube.

[0012] Preferably, the blowing and dispensing mechanism includes a rotating shaft rotatably connected to a circulating water pipe. A drive impeller is fixedly connected to the outer wall of the rotating shaft inside the circulating water pipe. Multiple rotating blocks are fixedly connected to the outer wall of the rotating shaft outside the circulating water pipe. Multiple fan blade sleeves are fixedly connected to the outer wall of the rotating blocks. A telescopic spring is fixedly connected inside the fan blade sleeve. A limit plate is fixedly connected to the end of the telescopic spring away from the fan blade sleeve. Multiple inlet hoses are fixedly connected to the outer wall of the rotating blocks. A fan blade is fixedly connected to the end of the limit plate away from the telescopic spring, and the end of the fan blade away from the limit plate slides to the outside of the fan blade sleeve.

[0013] Preferably, the interiors of the rotating shaft, the rotating block, and the fan blades are all hollow, the interiors of the rotating shaft and the rotating block are connected, and the outer wall of the fan blades has multiple spray holes.

[0014] Preferably, a sliding groove is provided at one end of the fan blade sleeve, and the end of the fan blade away from the limiting plate extends slidably to the outside of the fan blade sleeve through the sliding groove. The outer wall of the limiting plate and the inner wall of the fan blade sleeve are slidably fitted together.

[0015] Preferably, the end of the feed hose away from the rotating block is connected to the fan blade, and the fan blade is connected to the interior of the rotating block through the feed hose.

[0016] A method for heat treatment of a fan stator includes:

[0017] Step 1: When the staff is cooling the heat-treated fan stator, they first place the fan stator to be cooled below the air collection box and below the rotating disk. At this time, the servo motor and water pump are turned on.

[0018] Step 2: When the water pump is working, the cooling water filled inside the rotating tube can be circulated through the curved circulating water pipe;

[0019] Step 3: When the water pump circulates the cooling water, the impact of the water flow causes the drive impeller to rotate, which in turn drives the rotating shaft to rotate.

[0020] Step 4: When the rotating tube rotates, it drives the rotating disk to rotate, which in turn drives the multiple cleaning rollers at its bottom to rotate. In this way, the multiple cleaning brushes connected to the outer wall of the cleaning rollers rotate and remove dust from the surface of the fan stator.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This invention proposes a heat treatment device and method for a fan stator. Through the action of the blowing agent dispensing mechanism, the rotation of the fan blade sleeve and blades generates airflow. Combined with the air cooling effect of the rotating circulating water pipe inside the air collection box, the cooling effect inside the air collection box is increased. Simultaneously, the rotating spray of alcohol, falling through the through-hole above the rotating disk onto the surface of the fan stator, absorbs heat and lowers the stator's temperature. This solves the problem of simply relying on airflow to dissipate heat, which reduces the efficiency of cooling the heat-treated fan stator. It directly reduces the temperature on the outer wall of the fan stator, thereby improving the efficiency of cooling the heat-treated fan stator. Attached Figure Description

[0035] For purposes of simplicity and illustration, the principles of the embodiments are described primarily by way of example. In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other. Example

[0036] Please see Figures 1 to 8 As shown, the present invention provides a technical solution for a heat treatment device and method for a fan stator: a heat treatment device and method for a fan stator includes a workbench 1, support plates 2 installed on both sides of the top of the workbench 1, and an air collection box 3 installed on the top of the support plates 2. It also includes a rotating cooling mechanism for cooling the interior of the air collection box 3. The rotating cooling mechanism is located inside the air collection box 3 and includes a servo motor 4 installed on the top of the outer wall of the air collection box 3. The output end of the servo motor 4 is fixedly connected to a rotating pipe 401, and the bottom of the rotating pipe 401 extends rotatably into the interior of the air collection box 3. A water pump 402 is connected to the outer wall of the rotating pipe 401, and a circulating water pipe 403 is connected to one side of the water pump 402.

[0037] In a further detailed description of the present invention, a storage chamber is provided inside the rotating tube 401, and the storage chamber is filled with cooling water. The water pump 402 is located below the storage chamber and is connected to the inside of the storage chamber. A rotating groove is provided on the top of the air collecting box 3, and the rotating tube 401 extends into the inside of the air collecting box 3 through the rotating groove. The circulating water pipe 403 is bent, and the end of the circulating water pipe 403 away from the water pump 402 is connected to the top of the outer wall of the rotating tube 401.

[0038] With the above technical solution, in specific use: when the staff cools the heat-treated fan stator, they first place the fan stator to be cooled below the air collection box 3 and below the rotating disk 505. At this time, the servo motor 4 and the water pump 402 are turned on, so that the servo motor 4 and the water pump 402 work. When the servo motor 4 works, it drives the rotating tube 401 to rotate, which in turn drives the multiple circulating water pipes 403 on its outer wall to rotate. The circulating water pipes 403 are filled with cooling water, so that when they rotate, they generate a cooling effect, which can cool the inside of the air collection box 3, thus cooling the fan stator located inside the air collection box 3.

[0039] When the suction pump 402 is working, the cooling water filled inside the rotating pipe 401 can be circulated through the curved circulating water pipe 403, which reduces the heating rate of the cooling water inside the circulating water pipe 403 and increases the utilization efficiency of the cooling water inside the circulating water pipe 403 accordingly. Example

[0040] Please see Figures 1 to 8 As shown, the air-blowing cooling mechanism is used to cool the interior of the air collection box 3 and the fan stator located below the interior of the air collection box 3. The air-blowing cooling mechanism is located on the rotating cooling mechanism. The air-blowing cooling mechanism includes a rotating shaft 6 rotatably connected to the circulating water pipe 403. A drive impeller 601 is fixedly connected to the outer wall of the rotating shaft 6 inside the circulating water pipe 403. Multiple rotating blocks 602 are fixedly connected to the outer wall of the rotating shaft 6 outside the circulating water pipe 403. Multiple fan blade sleeves 603 are fixedly connected to the outer wall of the rotating block 602. A telescopic spring 604 is fixedly connected inside the fan blade sleeve 603. A limiting plate 605 is fixedly connected to the end of the telescopic spring 604 away from the fan blade sleeve 603. Multiple feed hoses 606 are fixedly connected to the outer wall of the rotating block 602. A fan blade 607 is fixedly connected to the end of the limiting plate 605 away from the telescopic spring 604, and the end of the fan blade 607 away from the limiting plate 605 slides to the outside of the fan blade sleeve 603.

[0041] In a further detailed description of the present invention, the interiors of the rotating shaft 6, the rotating block 602, and the fan blade 607 are all hollow. The interiors of the rotating shaft 6 and the rotating block 602 are connected. The outer wall of the fan blade 607 has multiple spray holes. The end of the inlet hose 606 away from the rotating block 602 is connected to the fan blade 607. The interiors of the fan blade 607 and the rotating block 602 are connected through the inlet hose 606. One end of the fan blade sleeve 603 has a sliding groove. The end of the fan blade 607 away from the limiting plate 605 extends slidably to the outside of the fan blade sleeve 603 through the sliding groove. The outer wall of the limiting plate 605 and the inner wall of the fan blade sleeve 603 are slidably fitted together.

[0042] With the above technical solution, in specific use: when the water pump 402 circulates the cooling water, the impact of the water flow causes the drive impeller 601 to rotate. As the drive impeller 601 rotates, it drives the rotating shaft 6 to rotate, which in turn drives multiple rotating blocks 602 on its outer wall to rotate. This, in turn, drives multiple fan blade sleeves 603 and multiple fan blades 607 on its outer wall to rotate. Due to the centrifugal force of rotation, the fan blades 607 can slide towards the outside of the multiple spray holes on their outer wall, using the addition of alcohol inside the rotating shaft 6. The alcohol then enters the rotating blocks 602 and then, through the inlet hose 606, enters the fan blades 607. The alcohol is sprayed through multiple spray holes on the outer wall of the fan blade 607. With this structure, the rotation of the fan blade sleeve 603 and the fan blade 607 can generate wind. In addition, the rotation of the circulating water pipe 403 provides air cooling to the inside of the air collection box 3, which can increase the cooling effect of the air blowing inside the air collection box 3. At the same time, the alcohol is sprayed out by rotation and falls on the surface of the fan stator through the through hole above the rotating disk 505. This can absorb heat and cool the surface of the fan stator. This solves the problem of simply blowing away heat with wind, which reduces the efficiency of the workers in cooling the heat-treated fan stator. It can directly reduce the temperature generated on the outer wall of the fan stator, thereby improving the efficiency of the workers in cooling the heat-treated fan stator.

[0043] It should be noted that: an inlet hole is provided on the rotating shaft 6, through which alcohol is added into the interior of the rotating shaft 6; an inlet is provided on the outer wall of the rotating tube 401, through which cooling water is added into the interior of the storage chamber inside the rotating tube 401 via a square groove and an inlet. Example

[0044] Please see Figures 1 to 8As shown, a rotating dust removal mechanism is used to remove dust from the surface of the fan stator. The rotating dust removal mechanism is located below the rotating cooling mechanism. The rotating dust removal mechanism includes a sliding cavity 5 opened inside the rotating tube 401. A limiting slide plate 501 is slidably connected inside the sliding cavity 5. A sliding rod 502 is fixedly connected to the bottom of the limiting slide plate 501, and the bottom of the sliding rod 502 slides to the outside of the bottom of the rotating tube 401. A connecting rope 503 is connected to the outer wall of the rotating tube 401 located on the outer wall of the sliding cavity 5. A fixing bolt 504 is connected to the end of the connecting rope 503 away from the outer wall of the rotating tube 401. A rotating disk 505 is fixedly connected to the bottom of the sliding rod 502. Multiple fixing plates 506 are fixedly connected to the bottom of the rotating disk 505. A rotating rod 507 is rotatably connected between two fixing plates 506. A cleaning roller 508 is fixedly connected to the outer wall of the rotating rod 507 located between the two fixing plates 506.

[0045] In a further detailed description of the present invention, the outer wall of the cleaning roller 508 is connected to a plurality of cleaning brushes, the outer wall of the rotating tube 401 is provided with a plurality of bolt holes on the outer wall of the sliding cavity 5 and the outer wall of the sliding rod 502, and the plurality of bolt holes are arranged correspondingly. The fixing bolt 504 fixes the sliding rod 502 to the rotating tube 401 through the bolt holes. A square groove is provided on one side of the outer wall of the air collecting box 3 at the position of the fixing bolt 504, and a plurality of through holes are provided on the rotating disk 505.

[0046] With the above technical solution, in specific use: when cooling the fan stator, place the fan stator below the rotating disk 505, then slide the sliding rod 502 downwards to drive the rotating disk 505 and the cleaning roller 508 at its bottom to fit against the surface of the fan stator. Then, install the fixing bolt 504 into the bolt hole to fix the sliding rod 502 and the rotating tube 401.

[0047] When the rotating tube 401 rotates, it drives the rotating disk 505 to rotate, which in turn drives the multiple cleaning rollers 508 at its bottom to rotate. Based on the function of the multiple cleaning brushes connected to the outer wall of the cleaning rollers 508, the surface of the fan stator is rotated to remove dust, which can reduce the amount of dust on the surface of the fan stator after heat treatment and improve the performance of the fan stator after heat treatment.

[0048] Alcohol falls onto the surface of the fan stator through the through-hole. The rotation of the cleaning roller 508 allows the alcohol to fully contact the surface of the fan stator, thereby further increasing the cooling effect of the alcohol on the surface of the fan stator. This solves the problem of simply blowing away heat with air, which reduces the efficiency of workers in cooling the heat-treated fan stator. It can directly reduce the temperature generated on the outer wall of the fan stator, thereby improving the efficiency of workers in cooling the heat-treated fan stator. Example

[0049] Based on the above embodiments one to five, a heat treatment method for a fan stator is proposed, comprising the following steps:

[0050] Step 1: When the staff is cooling the heat-treated fan stator, they first place the fan stator to be cooled below the air collection box 3 and below the rotating disk 505. At this time, the servo motor 4 and the water pump 402 are turned on.

[0051] Step 2: When the water pump 402 is working, the cooling water filled inside the rotating pipe 401 can be circulated through the curved circulating water pipe 403.

[0052] Step 3: When the water pump 402 circulates the cooling water, the water flow impacts the drive impeller 601, causing it to rotate. When the drive impeller 601 rotates, it drives the rotating shaft 6 to rotate.

[0053] Step 4: When the rotating tube 401 rotates, it drives the rotating disk 505 to rotate, which in turn drives the multiple cleaning rollers 508 at its bottom to rotate. Thus, based on the function of the multiple cleaning brushes connected to the outer wall of the cleaning rollers 508, the surface of the fan stator is rotated to remove dust.

[0054] Although the illustrative specific embodiments of this application have been described above to enable those skilled in the art to understand this application, this application is not limited to the scope of the specific embodiments. For those skilled in the art, all applications utilizing the concept of this application are protected as long as various variations are within the spirit and scope of this application as defined and determined by the appended claims.
