Description

Technical Field

[0001] This utility model relates to the field of camera technology, and in particular to a heat insulation device for a steam turbine used in power generation. Background Technology

[0002] A steam turbine for power generation is a facility that can simultaneously produce electricity and heat. This model has high energy efficiency because it not only converts fuel into electricity but also recovers and reuses the waste heat generated during power generation for purposes such as heating or cooling.

[0003] A steam turbine is a rotary steam power plant and a major component of modern thermal power plants. It is also used in the metallurgical and chemical industries, as well as in ship propulsion systems. During operation, the steam turbine's temperature rises rapidly due to prolonged operation. Accidental contact with the turbine could result in burns, and the prolonged exposure to high temperatures significantly reduces its lifespan.

[0004] To prevent the safety hazard of burns, existing steam turbines for power generation are equipped with protective heat insulation devices that are fastened to the outside with bolts. Because of the bolt-fastened structure, it is inconvenient to quickly open the protective heat insulation devices when it is necessary to inspect the internal steam turbine.

[0005] Therefore, it is necessary to provide a heat insulation device for a steam turbine used in power generation to solve the above-mentioned technical problems. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figure 1 A schematic diagram of a preferred embodiment of a heat insulation device for a power generation steam turbine provided by this utility model; Figure 2 for Figure 1 The diagram shows a structural schematic of the outer shell structure. Figure 3 for Figure 1 The diagram shows the internal structure of the outer shell 2. Figure 4 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 5 for Figure 2 The enlarged schematic diagram of section B is shown below; Figure 6 for Figure 3 The enlarged schematic diagram of section C is shown. A heat insulation device for a steam turbine used in power generation includes: a base 1, two sets of support columns 2 are fixedly installed on the top of the base 1, and circular tubes 3 are inserted through the side walls of the two sets of support columns 2. A steam turbine body 11 is fixedly connected between the two sets of circular tubes 3. Two sets of support legs 7 are fixedly installed on the top of the base 1 between the two sets of support columns 2. A second outer shell 8 is fixedly installed on the top of the two sets of support legs 7. A first outer shell 4 is installed on the rear outer wall of the second outer shell 8 through several assembled hinges. A sealing assembly 15 is installed on the top of the second outer shell 8. Two sets of mounting blocks 12 are fixedly installed on the front side of the first outer shell 4. Two sets of mounting blocks 23 are fixedly installed on the front side of the second outer shell 8. A locking assembly 6 is installed between the two sets of mounting blocks 12 and the two sets of mounting blocks 23.

[0025] The locking assembly 6 includes a slide groove 61, which is located on the front side of mounting block 12. A guide rod 64 is fixedly installed between the inner walls of the left and right sides of the slide groove 61. A slider 62 is slidably connected between the outer wall of the guide rod 64 and the inner wall of the slide groove 61. A baffle 67 is fixedly installed on the front side of the slider 62. A limit block 65 is fixedly installed on the rear side of the lower end of the baffle 67. A limit groove 66 is opened on the side wall of mounting block 2 13, which penetrates the front side of mounting block 2 13. The limit block 65 is inserted into the limit groove 66. Both the limit groove 66 and the limit block 65 are T-shaped. When it is necessary to open the outer shell 1 4 and the outer shell 2 8, the baffle 67 is moved towards the entry end of the limit groove 66, so that the baffle 67 drives the limit block 65 to move out of the limit groove 66 with the assistance of the slider 62, thereby releasing the restriction between the outer shell 1 4 and the outer shell 2 8.

[0026] A spring 63 is fixedly installed between the side wall of the slider 62 and the inner wall of the groove 61. The spring 63 is sleeved on the outside of the guide rod 64. First, push the baffle 67 to make the slider 62 compress the spring 63. Then, align the outer shell 4 and the outer shell 8 and align the limiting block 65 with the limiting groove 66. Then, release the baffle 67. The spring 63 will automatically drive the slider 62 and the limiting block 65 on the back of the baffle 67 to insert into the limiting groove 66, thereby locking the outer shell 4 and the outer shell 8.

[0027] The sealing component 15 includes a groove 151, which is formed on the top of the outer shell 2 8. A sealing strip 152 is inserted and connected to the inner wall of the groove 151. When the outer shell 1 4 and the outer shell 2 8 are in contact, the top of the sealing strip 152 is in contact with the bottom of the outer shell 1 4, thereby sealing the gap at the connection and better locking in the temperature.

[0028] An exhaust pipe 5 is fixedly installed on the outer wall of the outer casing 4. A solenoid valve is installed inside the exhaust pipe 5. When the internal temperature of the outer casing 4 and the outer casing 8 rises, the solenoid valve opens, allowing the internal temperature of the outer casing 4 and the outer casing 8 to be cooled through the exhaust pipe 5.

[0029] A control device 10 is fixedly installed on the side wall of the support column 2. The control device 10 is electrically connected to the solenoid valve inside the exhaust pipe 5. The control device 10 is a PLC controller.

[0030] A handle 9 is fixedly installed on the front side of the outer casing 4, and a grip 14 is fixedly installed on the front side of the baffle 67. The handle 9 is designed to facilitate opening the outer casing 4, and the grip 14 is designed to facilitate pushing the baffle 67.

[0031] The working principle of the heat insulation device for a steam turbine used in power generation provided by this utility model is as follows:

[0032] The two sets of circular tubes 3 are respectively connected to external equipment. The locking component 6 can be used to quickly lock or open the outer casing 4 and the outer casing 8. The outer casing 4 and the outer casing 8 enclose the turbine body 11, which can improve the heat preservation of the turbine body 11. The sealing component 15 ensures that the connection between the outer casing 4 and the outer casing 8 will not allow heat to be lost.

[0033] Compared with related technologies, the heat insulation device for a steam turbine used in power generation provided by this utility model has the following beneficial effects:

[0034] When it is necessary to open the outer shell 4 and the outer shell 8, move the baffle 67 towards the entry end of the limiting groove 66, so that the baffle 67 drives the limiting block 65 to move out of the limiting groove 66 with the assistance of the slider 62, thereby releasing the restriction between the outer shell 4 and the outer shell 8. First, push the baffle 67 to compress the spring 63 with the slider 62. Then, align the outer shell 4 and the outer shell 8 and align the limiting block 65 with the limiting groove 66. Then, release the baffle 67. The spring 63 will automatically drive the slider 62 and the limiting block 65 on the back of the baffle 67 to insert into the limiting groove 66, thereby locking the outer shell 4 and the outer shell 8.

[0035] When the outer casing 14 and the outer casing 28 are in contact, the top of the sealing strip 152 is in contact with the bottom of the outer casing 14, thereby sealing the gap at the joint and better locking in the temperature.
