Description

Technical Field

[0001] This invention relates to the field of thermal power generation technology, and in particular to a device for monitoring the deformation of tube bundles in an air-cooled island. Background Technology

[0002] Air-cooled island is a descriptive term for the air cooling system in a power plant. During the winter heating season, it primarily provides heating services. At this time, the heat from the turbine exhaust to the air-cooled condenser is relatively low, making the system prone to freezing. Therefore, the trade-off between winter freeze protection and low back pressure economy in air-cooled systems is one of the issues we must consider under operating conditions. Through long-term observation and practice, effectively monitoring the deformation of the air-cooled heat dissipation tube bundles can serve as a criterion for determining whether the tube bundles are undercooled. Because the air-cooled island tube bundles are arranged in two symmetrical rows and are quite long, it is difficult to monitor the deformation of a single tube bundle. Existing monitoring equipment cannot automatically identify the location of the largest deformation deviation. Strengthening and fixing the location of the largest deviation allows staff to easily observe the location of the largest deformation and supports the tube bundle before maintenance.

[0003] In view of the above, we provide an air-cooled island tube bundle deformation monitoring device to solve the above problems. Summary of the Invention

[0004] In view of the above situation, the present invention provides an air-cooled island tube bundle deformation monitoring device. The support ring of the device can support the position of tube bundle deformation and can identify the maximum deformation value of the tube bundle during movement.

[0005] A deformation monitoring device for air-cooled island tube bundles includes a frame with a support ring overlapping the middle of the frame. A deformation monitoring mechanism is provided on the inner side of the support ring. The deformation monitoring mechanism includes a detection chamber, a sealing valve, a thin plate, and a control rod. The detection chamber is fixedly disposed on the inner side of the support ring. A rotatable protective mechanism is provided inside the support ring. The protective mechanism includes a drive gear, a rotating frame, and a control mechanism. The control mechanism includes a support bar, a detection bar, and a positioning bar. The support bar is slidably disposed on one side of the rotating frame, and the detection bar is slidably disposed on one side of the rotating frame. A detection block is provided on the lower surface of the detection bar. A first tooth is formed on the upper surface of the support bar, a second tooth is formed inside the support bar, and the positioning bar is disposed on one side of the detection bar.

[0006] The beneficial effects of the above technical solution are as follows:

[0007] The support ring designed in this scheme can support the location of tube bundle deformation and can identify the maximum deformation value of the tube bundle during movement. By finding the location of the maximum deformation and providing support, the tube bundle can be protected. It also makes it easy for staff to see the location of the deformation at a glance, which is convenient for maintenance. It can also prevent the tube bundle from being further deformed after it has been deformed, which would render the entire tube bundle unusable. Furthermore, it can record the maximum deformation value on a tube bundle by the amount of compressed gas, which can determine whether the tube bundle can still be used. Attached Figure Description

Detailed Implementation

[0022] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 13 As will be clearly shown in the detailed description of the embodiments, all structural contents mentioned in the following embodiments are based on the accompanying drawings.

[0023] This embodiment provides a deformation monitoring device for air-cooled island tube bundles, as shown in the attached document. Figure 1-3 As shown in the attached instruction manual Figure 1 As shown, this design illustrates the general shape of the island 34 (the frame can have multiple sets of support rings, but this design only shows one set) for ease of understanding. First, let's explain how the frame 1 operates. The frame 1 has two external rods 37 on each side. Note that the external rods 37 are shown as suspended in the diagram. In reality, the island 34 is installed on the top floor, and these external rods 37 need to be installed on the building's top floor. Therefore, the external rods 37 need to be fixed using external structural elements, which is why they are shown suspended in this design. The external rods 37 are actually installed on the building's top floor and allow the frame 1 to slide diagonally along the island 34. Because the external rods 37 are fixed, their surfaces have gear grooves. Lifting gears 38 are rotatably mounted on both sides of the frame 1. The lifting gears 38 are driven by a motor, allowing the frame 1 to slide smoothly along the island 34. The smooth sliding of the island 34 indicates that the support rings 2 can slide smoothly. This is the instruction manual attached... Figure 1 The displayed content is attached to the instruction manual. Figure 2 Included with instruction manual Figure 1 A side view of the cut (note that half of the part has been cut; the side shown is also the cut surface, with island 34 cut along the middle), see the instruction manual. Figure 3It can be seen that the ground layout of support ring 2 has a contact frame (cut off) and a contact rod. Only a portion of the contact frame is shown in the figure. The contact rod is a type of electric push rod that can extend and retract. One end of the contact frame is stuck on the frame 1. When support ring 2 detaches from frame 1, the contact rod causes support ring 2 to detach from frame 1 and fixes support ring 2 at the bending position of the tube bundle for support. When support ring 2 in this scheme finds the position of maximum deformation, the contact rod will retract to control one side of the contact frame to push against the round rod (see the attached manual). Figure 3 The diagram shows two round rods, one on each side. The support ring 2 is slidably mounted on these rods. These round rods, like the external rod 37, also need to be fixed to the top floor of the building and are solid rods. In this design, they are fixed to the island 34. However, they don't actually need to be installed on the island 34. The round rods provide a fixing platform for the support ring 2, facilitating its fixation to the rod when detached from the frame 1, and then supporting the deformation points. The principle behind fixing the support ring 2 to the round rod is explained in the attached instruction manual. Figure 3 A friction plate is provided on one side of the release bracket 36 shown. By retracting the release rod 35, the side with the friction plate abuts against the round rod, generating friction. This is why the support ring 2 can support the deformation of the suspended support tube bundle. (See the attached instruction manual.) Figure 1 The two rows of tubes arranged side by side in the middle are the tube bundles of the air-cooled island;

[0024] As attached Figure 4-6 As shown, the instruction manual is attached. Figure 4 The release mechanism 36 was fully displayed, corresponding to the instructions included. Figure 3 The missing release frame 36 and support ring 2 are key support structures in this scheme. A detection bladder 3 is located at the inner arc of support ring 2. This detection bladder 3 is compressible and deformable. It is a soft bladder with a fixed shape, made of shape-memory material, maintaining its original shape without external force and capable of deformation recovery. Therefore, when the tube body deforms, it compresses the detection bladder 3, forcing the air inside to one side of the sealing valve 4. The position of the sealing valve 4 indicates the degree of tube bundle deformation; simply put, the more air squeezed out of the detection bladder 3... This indicates that the greater the deformation of the tube bundle, the more likely it is to deform in any direction around the center, thus forming an angled curve (which is the location of the maximum deformation described in this solution; it should be noted that the accuracy of this solution is not very high, and the problem solved is to identify the location of the maximum deformation. If a tube bundle has multiple sets of deformations, this solution identifies and fixes this point). The identification and judgment process of this solution is described below. In this solution, the frame 1 needs to drive the support ring 2 to rotate back and forth to determine the location of the maximum deformation, for example, as shown in the instruction manual. Figure 1As the frame 1 moves upward, the maximum deformation along this path will be detected. During the return journey from top to bottom, the maximum deformation will be found. One step is to detect the maximum deformation, and the other is to find the location of the maximum deformation. This is the entire process of this scheme. After finding the location, the frame detaches from the frame 1 as described in the previous paragraph, and then the tube bundle is supported. This is the entire process of this scheme. The maximum deformation of a tube bundle is found (identified by the air squeezed by the detection bladder 3), and then the location of this deformation is found for support.

[0025] As attached Figure 7-13 As shown in the previous section, this section describes the process of finding the maximum deformation and providing support. The rotating frame 7 is rotatably mounted inside the support ring 2. The rotatable design of the rotating frame 7 is to locate the bending direction of the tube bundle and provide support at the bending point. The drive gear 6 is rotatably mounted on the rotating frame 7, and the motor is located above the drive gear 6. The motor drives the drive gear 6 to rotate. A groove corresponding to the drive gear 6 is provided on the inner wall of the support ring 2 to facilitate the rotation of the rotating frame 7, as shown in the attached instruction manual. Figure 7 As shown, at this point, the support strip 10 has extended to its maximum. The rotating frame 7 corresponds to the bending position of the tube bundle. This scheme determines the bending position of the tube bundle by first retracting the support strip 10 and then extending it a short distance around the circumference. (This is because the tube bundle bend forms a triangular angle; the support strip 10 is closest to the rotating frame 7 when it is positioned to one side at this angle. When the angle does not correspond to the support strip 10, it will be extended. This is why the bending position of the tube bundle is determined by first retracting the support strip 10 and then extending it a short distance. This short distance is very small and will be explained below, as shown in the attached instruction manual.) Figure 7 The deformation point shown is located counterclockwise on the support strip 10. When the support strip 10 rotates counterclockwise, it will first move towards the rotating frame 7. Because the tube bundle's compression presses against one side of the support strip 10, it slides towards the rotating frame 7 until it reaches the bending point. If rotation continues, the support strip 10 will move away from the rotating frame 7. This point of movement needs to be detected by the detection strip 8. The following describes the detection strip 8, positioning strip 9, and support strip 10. All three support bars 10 are slidably mounted on the rotating frame 7. The rotating frame 7 has corresponding limit rods to facilitate the sliding of the three bars, and each is supported by a spring. For example, spring 20 is used to extend the support bar 10, and spring 21 is located in the middle of the positioning bar 9. Here, we need to introduce the shape of the support bar 10. The middle of the support bar 10 adopts a hollow structure, which makes it easy for one side of the positioning bar 9 to be inserted into the hollow of the support bar 10 (one side of the positioning bar 9 extends into a long strip, as shown in the instruction manual). Figure 11As shown, the opening in the middle of the positioning strip 9 facilitates overlap with one side of the inspection strip. The positioning strip 9 is an L-shaped strip. When the support strip 10 moves along the steps above, it will first move towards the moving frame, and the first tooth 12 on top will overlap with the inspection block. The inspection block cannot detach from the inspection strip 8. Once the support strip 10 moves away and extends to the right, which is also the judgment point, the support strip 10 first approaches the rotating frame 7 and then moves away from the rotating frame 7, which will drive the inspection strip 8 to move. A gap is provided between the inspection strip 8 and the rotating frame 7. The detection spring 22 is equipped with a pressure sensor. Once the detection spring 22 detects a pressure sensor, the internal rotation of the support ring 2 will stop. This is the deformation point identification completed by the support bar 10 first approaching the rotating frame 7 and then moving away from the rotating frame 7 a certain distance, as described in this solution. After the support bar 10 moves the detection bar 8, it indirectly releases the positioning bar 9 because one end of the detection bar 8 is stuck in the positioning bar 9. The detection bar 8 moves, and the positioning bar 9 moves downward under the pull of the second spring 21, as shown in the attached instruction manual. Figure 11 As shown, the right extension of the positioning strip 9 overlaps with the second tooth 13, preventing the support strip 10 from being retracted (effectively fixing the support strip 10 and securing the deformed area). This is the function of the support strip 10. Finally, another function of this design is the retraction function. To facilitate the reuse of the support ring 2, a drive wheel 15 is integrally installed below the drive gear 6. When the drive wheel 15 rotates, it can restore the positioning strip 9, support strip 10, and detection strip 8 to their initial state. (The description of the restoration of the positioning strip 9, support strip 10, and detection strip 8 is attached.) Figure 11 It appears as shown in the instructions, but the support strip 10 needs to move towards the rotating frame 7 and be positioned by the positioning strip 9. Figure 8 As shown, at this time, the drive gear 6 rotates clockwise. This rotation of the drive bar 26 pushes against an extension rod on the support bar 10, causing the drive bar 26 to retract the support bar 10. Simultaneously, it drives the transmission wheel 23 to rotate. The transmission wheel 23 is meshed with one side of the drive wheel 15. The transmission wheel 23 drives the actuating bar 24 to move towards the positioning bar 9, causing the positioning bar 9 to move upwards, thus locking the detection bar 8 into position. Please refer to the attached instruction manual. Figure 9As shown, a slanted opening, or drive groove 16, is provided on one side of the drive wheel 15. When the drive wheel 15 rotates, the overlapping block 17 enters the drive groove 16. Under the limitation of the drive groove 16, the overlapping block 17 is lifted upwards. This upward lifting of the overlapping block 17 drives the detection block 11 to rise simultaneously, causing the detection block 11 to detach from the support strip 10. The support strip 10 can then be retracted. This illustrates the effect of clockwise rotation of the drive wheel 15. Reverse rotation of the drive wheel 15 will not affect the positioning strip 9, support strip 10, and detection strip 8 in this design. Because the transmission wheel 23 is a damaged gear, when it rotates to a certain position, it will... The surface is slipped, and the No. 4 spring 25 keeps it in contact with the drive wheel 15, so that the drive wheel 15 can adjust its direction and re-engage with the transmission wheel 23. The drive groove 16 also has a one-way rotating plate 19. When the drive wheel 15 adjusts its direction, the overlapping block 17 will rotate from the right side of the one-way plate 19 at most (the rotation center of the one-way plate 19 is equipped with a torsion spring), and will not reach above the drive wheel 15. The overlapping block 17 will not rise, and will not affect the detection block 11 to engage with the support strip 10. Similarly, the drive strip 26 is also one-way rotating and has a torsion spring 14, which will not affect the normal support of the support strip 10.

[0026] Finally, this method describes how to record the air expelled from the detection capsule 3. Please refer to the attached instruction manual. Figure 13 The sealing valve 4 slides on the upper surface of the support ring 2. When the detection bladder 3 compresses gas, it compresses the shape of the sheet 39. The sheet 39 is a soft sheet. The upward deformation of the sheet 39 compresses the lifting spring 32. One end of the lifting spring 32 is not connected to the sheet 39. The lifting spring 32 is also equipped with a pressure sensor. Once pressure is applied, it will cause the control rod 5 to extend. The control rod 5 is also an electric push rod, controlled by the lifting spring 32. It stops extending when the lifting spring 32 no longer displays pressure. This indirectly expresses the degree of compression of the detection bladder 3. The sealing valve 4 has a recording block 28 attached to one side of its extension. The recording block 28 moves unidirectionally on the recording strip 27. When the sealing valve 4 rises, it will cause the recording block 28 to slide until the maximum height, that is, the maximum degree of deformation, is found. This scheme uses a back-and-forth positioning. The maximum amount of tube bundle deformation is found only when the bottom of the release rod 35 is re-contacted during the return process. Because the sealing valve 4 has a recognition spring on one side, the release spring is attached to the instruction manual. Figure 13The device is in a compressed state. Once the release spring is compressed during the first cycle, it indicates that the maximum deformation position has been reached (the release spring will not be activated during the first cycle in this design). To enable this design to be used multiple times, a telescopic rod 29 and a contact block are provided. The telescopic rod 29 is an electric push rod, and the contact block slides on one side of the telescopic rod 29 via a spring. The telescopic rod 29 retracts to engage the recording strip 27. A support ring 2 is attached to the middle of the frame 1. A deformation monitoring mechanism is provided on the inner side of the support ring 2.
