Description

Technical Field

[0001] This utility model relates to the technical field of condenser compensator structure, specifically a condenser compensator structure with an adjustment section. Background Technology

[0002] The condenser compensator section is a key component at the connection between the condenser and the turbine exhaust cylinder. Its core function is to compensate for installation errors and absorb thermal displacement during operation, ensuring the safe and stable operation of the unit.

[0003] The compensating section structure used in existing condensers lacks adjustment measures, which makes the compensating section structure fixed. Furthermore, since the distance between the connection between the condenser and the turbine exhaust cylinder is different, it is impossible to install the compensating section structure if it is short. Therefore, those skilled in the art have provided a condenser compensating section structure with an adjustment section to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a condenser compensation section structure with an adjustment section to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a condenser compensation section structure with an adjustment section, comprising a bellows, with a first flange and a second flange respectively connected to both ends of the bellows. Two connecting discs are symmetrically and rotatably connected to the top of the second flange, and a drive screw is rotatably connected to the top of each of the two connecting discs. A lifting pipe is threaded onto the outer wall of the drive screw, and a connecting block is fixedly connected to the top of the lifting pipe. Two sets of rectangular blocks are symmetrically and fixedly connected to the bottom of the first flange, with two rectangular blocks in each set. The opposite side of the two rectangular blocks is rotatably connected to both sides of the connecting block.

[0006] As a further embodiment of this utility model: the top of the second flange is symmetrically fixedly connected with round blocks, and one side of each round block is rotatably connected with a rotating shaft. The bottom of the connecting plate is symmetrically fixedly connected with two semicircular blocks, and the opposite side of the two semicircular blocks is rotatably connected to both sides of the rotating shaft.

[0007] As a further embodiment of this utility model: two second torsion springs are symmetrically sleeved on the outer wall of the rotating shaft, and the opposite ends of the two second torsion springs are fixedly connected to the two sides of the rotating shaft respectively, and the opposite ends of the two second torsion springs are fixedly connected to the inner sides of the two semicircular blocks respectively.

[0008] As a further embodiment of this utility model: a first damping shaft is rotatably inserted through one side of the connecting block, and the two ends of the first damping shaft are respectively fixedly connected to the inner sides of two rectangular blocks. Two first torsion springs are symmetrically sleeved on the outer wall of the first damping shaft, and the opposite ends of the two first torsion springs are respectively fixedly connected to the two sides of the connecting block, and the opposite ends of the two first torsion springs are respectively fixedly connected to the inner sides of the two rectangular blocks.

[0009] As a further improvement of this utility model: a rotating handle is fixedly sleeved on the outer wall of the drive screw, and the rotating handle is located directly below the lifting tube.

[0010] As a further improvement of this utility model: the two lifting pipes are located on both sides of the corrugated pipe, and both lifting pipes are vertically arranged.

[0011] As a further improvement of this utility model: the first flange and the second flange have the same diameter, and the lifting pipe surrounds the drive screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When the handle is turned, the drive screw can be driven to rotate. After the drive screw rotates, the lifting pipe can be driven to rise. At this time, the lifting pipe will drive the connecting block and the two rectangular blocks to rise simultaneously. Then, the two rectangular blocks will lift the first flange. The first flange will gradually move away from the second flange and stretch the length of the bellows, thereby adjusting the length of the bellows and adapting to the spacing between the condenser and the turbine exhaust cylinder.

[0014] This utility model is simple to use. The second flange and the first flange are reset by the second torsion spring and the first torsion spring respectively, so that the second flange and the first flange can automatically return to their original positions after swinging. Rotating the drive screw can drive the lifting pipe to move the first flange away from the second flange. This can stretch the length of the bellows to adapt to the distance at the connection between the condenser and the turbine exhaust cylinder. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 In this embodiment of the present invention, a condenser compensation section structure with an adjustment section includes a bellows 1. The two ends of the bellows 1 are respectively connected to a first flange 2 and a second flange 3. The top of the second flange 3 is symmetrically and rotatably connected to two connecting plates 4, and the top of each of the two connecting plates 4 is rotatably connected to a drive screw 14. The outer wall of the drive screw 14 is threaded with a lifting pipe 6, and the top of the lifting pipe 6 is fixedly connected to a connecting block 8. The bottom of the first flange 2 is symmetrically and fixedly connected to two sets of rectangular blocks 7, and each set of rectangular blocks 7 consists of two blocks. The opposite side of the two rectangular blocks 7 is rotatably connected to both sides of the connecting block 8.

[0022] In this embodiment, the top of the second flange 3 is symmetrically fixedly connected with round blocks, and one side of each round block is fixedly connected with a rotating shaft 13. The bottom of the connecting plate 4 is symmetrically fixedly connected with two semi-circular blocks 11, and the opposite side of the two semi-circular blocks 11 is rotatably connected to both sides of the rotating shaft 13.

[0023] In this embodiment, two second torsion springs 12 are symmetrically sleeved on the outer wall of the rotating shaft 13. The opposite ends of the two second torsion springs 12 are fixedly connected to the two sides of the rotating shaft 13, and the opposite ends of the two second torsion springs 12 are fixedly connected to the inner sides of the two semicircular blocks 11.

[0024] In this embodiment, a first damping shaft 10 is fixedly embedded through one side of the connecting block 8, and the two ends of the first damping shaft 10 are fixedly connected to the inner sides of the two rectangular blocks 7 respectively. Two first torsion springs 9 are symmetrically sleeved on the outer wall of the first damping shaft 10, and the opposite ends of the two first torsion springs 9 are fixedly connected to the two sides of the connecting block 8 respectively, and the opposite ends of the two first torsion springs 9 are fixedly connected to the inner sides of the two rectangular blocks 7 respectively.

[0025] In this embodiment, a rotating handle 5 is fixedly sleeved on the outer wall of the drive screw 14, and the rotating handle 5 is located directly below the lifting tube 6.

[0026] In this embodiment, the two lifting pipes 6 are located on both sides of the corrugated pipe 1, and both lifting pipes 6 are vertically arranged.

[0027] In this embodiment, the first flange 2 and the second flange 3 have the same diameter. The lifting pipe 6 surrounds the drive screw 14. The rectangular block 7 can be rotated by the first damping shaft 10, which can adjust the swing angle of the first flange 2. When torsion occurs, multiple first torsion springs 9 will be stressed. When the stress ends, the torque of the multiple first torsion springs 9 can drive the first damping shaft 10 to rotate and reset, so that the first flange 2 returns to its original state after the stress ends. The second flange 3 can swing by two shafts 13, and the two second torsion springs 12 can also drive the second flange 3 to return to its original state after the stress ends.

[0028] The working principle of this utility model is as follows: the first flange 2 and the second flange 3 can be connected to the condenser and the turbine exhaust cylinder respectively. When the handle 5 is turned, the drive screw 14 can be driven to rotate. After the drive screw 14 rotates, it can drive the lifting pipe 6 to rise. At this time, the lifting pipe 6 will drive the connecting block 8 and the two rectangular blocks 7 to rise at the same time. At that time, the two rectangular blocks 7 will lift the first flange 2. The first flange 2 will gradually move away from the second flange 3 and stretch the length of the bellows 1, thereby adjusting the length of the bellows 1 and adapting to the distance between the condenser and the turbine exhaust cylinder.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
