Description

Technical Field

[0001] This utility model relates to the technical field of air-cooled island cleaning devices, and in particular to an anti-tilting structure for a 600MW unit air-cooled energy-saving and efficiency-enhancing robot. Background Technology

[0002] Regular cleaning of the heat dissipation fins in air-cooled islands has significant energy-saving and efficiency-enhancing benefits. During operation, dust, oil, and particulate matter accumulated on the fin surface create thermal resistance, severely hindering heat transfer from steam to air. This leads to decreased heat dissipation efficiency, increased back pressure, and consequently, reduced turbine thermal efficiency and increased coal consumption. Cleaning effectively restores fin cleanliness, improves heat exchange capacity, reduces exhaust back pressure, and increases unit vacuum, thereby improving power generation efficiency.

[0003] In existing technologies, cleaning components mostly use rigid frames to connect the upper and lower guide rails, relying on high-precision tracks and active control systems to maintain balance. Once the tracks become non-parallel or locally twisted due to thermal deformation, installation errors, or structural settlement, the rigid structure cannot self-adjust, which easily leads to stress concentration, causing running jams, wheel derailment, or even overall structural tilting, and there is a possibility that the robot may collide with the heat sink fins.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6This utility model provides an embodiment: an anti-tilting structure for an air-cooled energy-saving and efficiency-enhancing robot for 600MW units. The system includes a mounting platform 21 installed on an air-cooled island 1. The mounting platform 21 has a first mounting surface 211 and a second mounting surface 212. A lower moving unit 4 is installed on the first mounting surface 211, and an upper moving unit 3 is installed on the second mounting surface 212. The upper moving unit 3 and the lower moving unit 4 have the same structure. A drive unit is installed on the upper moving unit 3 and the lower moving unit 4 respectively. An adaptive component is connected to both the upper moving unit 3 and the lower moving unit 4. The adaptive component includes a connecting plate 54. A cleaning robot 55 is installed on the connecting plate 54. The cleaning robot 55 includes a rotating block 552 that is rotatably connected. The rotating block 552 is provided with a water spray pipe 553 for spraying water onto the heat dissipation fins 11 on the air-cooled island 1. By using the upper moving unit 3 and the lower moving unit 4 for coordinated support, and with the independent adaptive component, the cleaning robot 55 can be stably suspended and flexibly operated on the air-cooled island 1, effectively avoiding attitude instability caused by single-point support or rigid connection, and significantly improving the safety and coverage of the cleaning operation.

[0020] Please see Figure 1-6 A further solution based on this embodiment is as follows: the adaptive component includes a first fixed block 51 fixed on the upper moving unit 3 and a second fixed block 56 fixed on the lower moving unit 4. A moving block 52 is provided between the first fixed block 51 and the second fixed block 56. The lower side of the moving block 52 is flexibly connected to the connecting plate 54. Through the split structure design of the fixed block and the moving block 52, the connecting plate 54 can achieve adaptive posture adjustment when there is geometric deviation between the upper and lower support points. This effectively absorbs the problem of non-parallelism of the slide rail 332 caused by thermal deformation of the air-cooled island 1, installation error or structural settlement, and prevents the cleaning robot 55 from getting stuck or overturning.

[0021] Please see Figure 1-4 A further solution based on this embodiment is as follows: The top of the moving block 52 is provided with a guide rod 521 that passes through the fixed block 51. A baffle 523 is installed on the top of the guide rod 521. A spring 522 is sleeved on the guide rod 521 between the fixed block 51 and the baffle 523. The spring 522 forms a buffer mechanism, which can alleviate the pulling on the connecting plate 54 during the operation of the robot and reduce the impact of dynamic load on the structure. At the same time, the spring 522 provides preload to ensure that the moving block 52 can automatically return to the correct position after offset, improve the stability of the system operation, and is suitable for the slide rail 332 with poor parallelism.

[0022] Please see Figure 1-4A further solution based on this embodiment is as follows: A first universal joint 531 is provided below the moving block 52. One end of the first universal joint 531 is connected to the fixed block 51, and the other end of the first universal joint 531 is connected to the moving block 52. The first universal joint 531 gives the upper connecting structure a multi-degree-of-freedom adjustment capability, so that the moving block 52 can passively adapt to the spatial posture changes of the upper moving unit 3, realize automatic compensation for local deformation or tilt of the upper slide rail 332, and enhance the flexibility and environmental adaptability of the overall structure.

[0023] Please see Figure 2-5 A further solution based on this embodiment is as follows: a second universal joint 532 is provided at the bottom of the connecting plate 54. One end of the second universal joint 532 is connected to the connecting plate 54, and the other end of the second universal joint 532 is connected to the fixing block 56. The second universal joint 532 realizes the flexible connection between the connecting plate 54 and the lower moving unit 4, and forms a "dual universal joint cooperative adaptive" mechanism with the upper first universal joint 531 to solve the stress concentration and operation jamming problems caused by rigid connection.

[0024] Please see Figure 2-5 A further solution based on this embodiment is as follows: the cleaning robot 55 is equipped with a drive motor 554 for driving the rotating block 552 to rotate, the bottom of the cleaning robot 55 is provided with a cable passage hole, and a waterproof cover can be placed on the right side of the cleaning robot 55. The drive motor 554 drives the rotating block 552 to realize the swing cleaning of the water spray pipe 553, expand the water spray coverage angle, and improve the cleaning efficiency; the cable passage hole facilitates the orderly threading of cables, and the waterproof cover effectively seals the electrical compartment, significantly improving the waterproofness of the cleaning robot 55.

[0025] Please see Figure 1-5 A further solution based on this embodiment is as follows: the upper moving unit 3 includes a slide rail 332 mounted on the mounting platform 21, a slider 311 slidably connected on the slide rail 332, and a mounting block 31 mounted on the slider 311. The slide rail 332 and the slider 311 form a guiding system to ensure that the upper moving unit 3 runs along a predetermined trajectory.

[0026] Please see Figure 2-4 A further solution based on this embodiment is as follows: a rack 331 is also installed on the mounting platform 21, and the drive unit includes a mounting plate 32 set on the mounting block 31. A waterproof motor 321 is installed on the mounting plate 32. The output end of the waterproof motor 321 passes through the mounting plate 32 and is connected to a gear 322 corresponding to the rack 331. The transmission through the meshing of the gear 322 and the rack 331 has the advantages of high transmission accuracy, strong load-bearing capacity and rapid response. With the waterproof motor 321, the cleaning robot 55 can be moved under harsh working conditions.

[0027] For another embodiment of the drive unit, please refer to [link / reference]. Figure 6A further solution based on this embodiment is as follows: The drive unit includes a mounting plate 32 mounted on the mounting block 31. A waterproof motor 321 is mounted on the mounting plate 32. The output end of the waterproof motor 321 passes through the mounting plate 32 and is connected to a take-up reel 61. Elevating blocks 631 are mounted on the front and rear sides of the mounting platform 21. A rubber-coated steel wire rope 62 is wound inside the take-up reel 61. The rubber-coated steel wire rope 62 includes a first end and a second end. The first end and the second end are respectively attached to the top of the elevating blocks 631 on the front and rear sides. The elevating blocks 631 are also provided with pressure blocks 632 for pressing the first end or the second end. By adopting the traction method of rubber-coated steel wire rope 62, the structure is simple, the cost is low, and the installation is convenient. The rubber coating enhances the friction and prevents slippage. The take-up reel 61 is driven by the waterproof motor 321 to realize the take-up and release of the line. The end pressing structure ensures that the traction process is stable and reliable.

[0028] Working principle: The upper moving unit 3 and the lower moving unit 4 move synchronously back and forth along the slide rail 332 on the mounting platform 21. Their power source can be either gear 322 and rack 331 transmission or traction by a rubber-coated steel wire rope 62. When using gear 322 and rack 331, the waterproof motor 321 drives the gear 322 to mesh with the rack 331 to achieve precise linear motion. When using steel wire rope traction, the waterproof motor 321 drives the take-up reel 61 to take up and release the rubber-coated steel wire rope 62, achieving stable traction through a structure fixed at both ends to the raised blocks 631. During movement, if the upper and lower guide rails become non-parallel or experience local fluctuations due to thermal deformation or installation errors, the fixed blocks 51 and 56 fixed to the upper and lower moving units 4 will have relative positional deviations. At this time, the moving block 52 adapts to the posture change through the first universal joint 531. Simultaneously, the guide rod 521 at its top and the spring 522 form a buffer mechanism, which can alleviate the pulling on the connecting plate 54 during robot operation. The connecting plate 54 is flexibly connected to the lower part through the second universal joint 532, forming a two-point adaptive support with the upper part, so that the overall posture of the cleaning robot 55 can be passively adjusted. At the same time, the drive motor 554 inside the cleaning robot 55 drives the rotating block 552 to swing, so that the water spray pipe 553 can achieve wide-angle water spray cleaning. The cable is introduced through the cable hole at the bottom of the connecting plate 54. The left side of the connecting plate 54 is provided with a tank chain fixing plate to facilitate the installation of the tank chain. The tank chain houses the cable and the high-pressure water pipe. When the high-pressure water pipe is connected to the water spray pipe 553, a clamp is also required to increase the connection stability, thereby achieving efficient, stable and full-coverage cleaning of the heat dissipation fins 11 of the air-cooled island 1. The synchronous drive method of the drive motor 554, the waterproof motor 321, the air-cooled island 1, the waterproof motor 321 of the upper moving unit 3 and the waterproof motor 321 of the lower moving unit 4 are all existing technologies, and the corresponding control methods and electrical control wiring methods are also known to those skilled in the art.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
