[0002] A steam turbine, also known as a steam turbine engine, is a rotary steam power device that can pass high-temperature and high-pressure steam through a fixed nozzle to become an accelerated airflow and then spray it onto the blades, causing the rotor with blade rows to rotate, converting the thermal energy of the steam into mechanical energy for the rotation of the turbine rotor to perform external work. Steam turbines are the main equipment in modern thermal power plants and are also used in the metallurgical industry, chemical industry, and ship power devices.
[0003] The partition in the steam turbine is a circular plate-shaped component installed in the turbine cylinder and divides the cylinder into several chambers with different pressures. Its main function is to install nozzles or stationary blades and prevent inter-stage steam leakage.

[0038] The working principle and beneficial effects of the above technical scheme are as follows: two semicircular baffle inner rings 1 are connected to form a complete circular baffle inner ring 1 through multiple connecting components 4, and two semicircular baffle outer rings 2 are connected to form a complete circular baffle outer ring 2 through multiple connecting components 4, and then the blades 3 are welded and fixed between the complete circular baffle inner ring 1 and the circular baffle outer ring 2, which facilitates the disassembly and assembly of the circular baffle inner ring 1 and the circular baffle outer ring 2 in the turbine cylinder, shortens the installation and disassembly time of the baffle in the cylinder, and reduces the time cost in production.
[0039] Example 2
[0040] On the basis of Example 1, Figure 1 , Figure 2As shown, the connecting component 4 includes a connecting groove 41, and the connecting ends of the partition inner ring 1 and the partition outer ring 2 are respectively provided with the connecting grooves 41, and mounting columns 42 are fixedly arranged in the two connecting grooves 41, and mounting blocks 43 are respectively inserted in the two connecting grooves 41, and the left and right ends of the mounting columns 42 are inserted on the two mounting blocks 43, and buffer pads 44 are arranged between the two ends of the mounting blocks 43 and the inner walls of the two connecting grooves 41, and a through groove 45 is vertically opened at the top of the connecting groove 41, and a connecting rod 46 is inserted in the through groove 45, and the connecting rod 46 vertically passes through the mounting columns 42 and the mounting blocks 43 and is fixed to the top and bottom of the connecting groove 41.
[0041] The working principle and beneficial effects of the above technical scheme are as follows: a connecting groove 41 is opened between the inner ring 1 of the semicircular partition and the inner ring 1 of the semicircular partition, and mounting columns 42 are fixedly arranged in the two connecting grooves 41 and the two connecting grooves 41 are merged, and a mounting block 43 is placed in the mounting groove, and the mounting columns 42 in the two connecting grooves 41 are inserted into the two ends of the mounting block 43, thereby enhancing the connection strength between the two semicircular partition inner rings 1, and the buffer pads 44 arranged between the two ends of the mounting block 43 and the inner walls of the two connecting grooves 41 reduce the stress generated when the two semicircular partition inner rings 1 are squeezed toward the middle, and the through groove 45 vertically penetrates the mounting block 43 and the mounting column 42 and inserts the connecting rod 46, so that the connecting rod 46 locks and strengthens the connection between the mounting block 43 and the mounting column 42 from other directions, thereby further enhancing the strength of the connection between the two semicircular partition inner rings 1, and the principle of enhancing the connection strength between the two semicircular partition outer rings 2 by the connecting component 4 is the same as above.
[0042] Example 3
[0043] On the basis of Embodiment 1-2, a production device for a prefabricated baffle for a steam turbine is applied to a prefabricated baffle for a steam turbine as described above, such as Figure 3 , Figure 4 , as shown, it is characterized in that it includes: an assembly table 5, a rotating component 7 is arranged at the bottom of the assembly table 5, a fastening component 6 is arranged at the top of the assembly table 5, the partition inner ring 1 and the partition outer ring 2 are respectively arranged on the assembly table 5, and the fastening component 6 is arranged on the inner and outer sides of the partition inner ring 1 and the partition outer ring 2.
[0044] The working principle and beneficial effects of the above technical scheme are as follows: the rotating component 7 supports and adjusts the angle of the assembly table 5, and the assembly table 5 supports and fixes the partition inner ring 1, the partition outer ring 2, and the fastening component 6. When the partition inner ring 1 and the partition outer ring 2 are fixed by the fastening component 6, the blade 3 is welded between the partition inner ring 1 and the partition outer ring 2 to prevent the partition inner ring 1 and the partition outer ring 2 from loosening during the welding process, thereby affecting the welding effect.
[0045] Example 4
[0046] On the basis of Example 3, Figure 3 , Figure 4 As shown, the fastening assembly 6 includes a limit tube 61 and a gas rod 62, a plurality of the gas rods 62 are arranged at the edge of the assembly platform 5, a plurality of the limit tubes 61 are slidably arranged on the assembly platform 5, the output end of the gas rod 62 is fixedly connected to the limit tube 61 on the side facing the outside of the assembly platform 5, the limit tube 61 is hollow, a sliding opening 611 is provided on the limit tube 61, a clamping plate 63 is arranged between the two limit tubes 61, and the two ends of the clamping plate 63 are respectively inserted into the sliding opening 611. In the movable mouth 611, a rotating column 64 is connected to the limiting tube 61 through a thread, and the bottom of the rotating column 64 abuts against the top of the clamping plate 63. The clamping plate 63 is provided with sliding grooves 65 inside and on the side thereof. A limiting column 66 is slidably arranged on the sliding groove 65 on the bottom surface of the clamping plate 63, and a fixed valve 67 is slidably arranged on the sliding groove 65 on the side surface of the clamping plate 63. The fixed valve 67 is connected to the top of the limiting column 66 through a thread, and a rotating handle 68 is arranged on the fixed valve 67.
[0047] The working principle and beneficial effects of the above technical scheme are as follows: the gas rod 62 pushes the limiting tube 61 to move on the slide rail 91 opened on the assembly table 5, and the limiting tube 61 squeezes the inner edge of the inner ring 1 of the partition and the outer edge of the outer ring 2 of the partition placed on the assembly table 5. A clamping plate 63 is arranged between the two limiting tubes 61, and the clamping plate 63 presses the inner ring 1 of the partition and the outer ring 2 of the partition on the assembly table 5 for fastening. The two ends of the clamping plate 63 are inserted into the limiting tube 61 from the sliding opening 611, and the rotating column 64 in the limiting tube 61 rotates the rotating column 64 toward the bottom of the limiting tube 61. When the bottom of the rotating column 64 abuts against the top of the clamping plate 63, the two ends of the clamping plate 63 are stuck by the two rotating columns 64, and the clamping plate 63 locks the inner ring 1 of the partition and the outer ring 2 of the partition on the assembly table 5. The two clamping plates opened on the clamping plate 63 A limiting column 66 and a fixed valve 67 are slidably arranged in each slide groove 65.

The fixed valve 67 is connected to the top of the limiting column 66 through a thread. The fixed valve 67 is rotated by turning the rotating handle 68. The fixed valve 67 penetrates deep into the top of the limiting column 66 through the thread. When the rotating handle 68 is tightly attached to the side of the clamping plate 63, the fixed valve 67 cannot move in the slide groove 65 of the clamping plate 63. At this time, the limiting column 66 is locked and does not move. The locked limiting column 66 further locks the position of the partition inner ring 1 and the partition outer ring 2, ensuring the stability of the partition inner ring 1 and the partition outer ring 2 during welding.

The magnet blocks 1072 drive the multiple active columns 1071 and the multiple clamping blocks 1073 to move toward the center direction of the two clamping frames 1068. The clamping blocks 1073 in two directions clamp the blade 3 in the middle. The clamping method of the multiple clamping blocks 1073 prevents the blade 3 from being deformed due to the clamping points being too concentrated during the clamping process.
