Description

Technical Field

[0002] At present, the turbine blade high-efficiency cooling structure device is a cooling device specially designed for turbine blades in steam turbines.

[0003] The existing technology is inefficient in releasing and dissipating steam. Traditional steam release mechanisms often rely on simple valve control and cannot achieve rapid and complete steam discharge. At the same time, the lack of an efficient heat dissipation mechanism leads to a slow steam dissipation speed. A large amount of steam remains inside the turbine body, affecting the subsequent heat dissipation effect and the safety of the equipment. The cooling system of the existing technology is not perfect. Traditional blade cooling methods mostly use a single cooling medium circulation and lack a multi-level and multi-dimensional cooling mechanism. In addition, only a single heat dissipation of the blades can be performed, and the blades cannot be cooled quickly and evenly. The blades are easily damaged by overheating, which shortens their service life. Furthermore, the cooling structure of the existing technology often requires manual control of the switching and adjustment of each component, which not only increases the difficulty of operation and labor intensity, but also easily leads to poor cooling effect or equipment damage due to improper operation.

[0020] like Figure 1~Figure 4As shown, the steam release component 201 includes a limit shell 21, a servo motor 23 and two large gears 222. The limit shell 21 is fixedly connected to the inside of the turbine casing 12. The two large gears 222 are rotatably installed at both ends of the limit shell 21. Four circumferentially evenly distributed connecting plates 22 are commonly connected to the two large gears 222. The connecting plates 22 are arranged in an arc shape with the front higher and the rear lower. The impeller 16 is arranged to fit the trend of the connecting plates 22. A plurality of equidistantly distributed partitions 221 are fixedly connected to the connecting plates 22. The servo motor 23 is installed at the bottom of the turbine casing 12. A straight shaft 231 is installed at the output end of the servo motor 23. Two symmetrically arranged small gears 232 are fixedly sleeved on the straight shaft 231.

[0023] In this embodiment, when the equipment is in use, steam is sent to the steam turbine body 1 through the steam connecting pipe 13.

The first cooling mechanism 2 is turned on by turning on the servo motor 23 in the steam release mechanism and the axial flow motor 241 in the steam dispersing component 202 respectively. The turning on of the servo motor 23 causes the straight shaft 231 to rotate. The rotation of the straight shaft 231 causes the two small gears 232 to rotate.

The synchronous rotation of the two rotating shafts 242 causes the two axial flow fan blades 243 on both sides of the turbine casing 12 to rotate synchronously, and sends the steam out of the turbine body 1, so that the steam inside the turbine body 1 is quickly dissipated, thereby facilitating subsequent heat dissipation.

[0024] Example 2 like Figure 1 to Figure 11 As shown, the circulation assembly 301 includes a circulation water pipe 321, a one-way valve 322, a first water pump 323, a second water pump 324 and two sealing rings 32.

The second cooling mechanism 3 is composed of a circulation component 301, an auxiliary cooling component 302 and a heat dissipation component 303. The second cooling mechanism 3 is started by turning on the first water pump 323, the second water pump 324 and the columnar refrigerator 352. The first water pump 323 and the second water pump 324 are turned on, so that water circulates through the circulating water pipe 321. The circulating water pipe 321 sends water to the sealing ring 32. The water in the sealing ring 32 is then sent to the inside of the connecting cavity 311 through the water inlet hole 31, and then flows from the connecting cavity 311 into the water cavity 162 in the blade 161 for cooling. In the process of water circulation cooling, the water flows from entering the multi-channel cooling device 301 to the cooling device 302. The water pipe 332 is circled to increase the flow distance of the water flow. At this time, the water wheel 34 rotates due to the flow of water flow. The rotation of the water wheel 34 causes the connecting shaft 341 to rotate. The connecting shaft 341 drives the follower shaft 343 to rotate through the transmission belt 342. The rotation of the follower shaft 343 causes the heat dissipation fan blades 344 to rotate, and the water in the multi-circle water pipe 332 is initially cooled. After the water flow is initially cooled, the water flow flows into the water distribution plate 351. The columnar refrigerator 352 on the water distribution plate 351 cools the water distribution plate 351 for secondary cooling. When the columnar refrigerator 352 is cooling, the cold air pipe 354 provides preliminary cooling cold air to the auxiliary cooling component 302, thereby improving the cooling efficiency of the blades 161.
