Description

Technical Field

[0001] This utility model relates to the field of air-cooled generator technology, and in particular to an upper drive device for an air-cooled energy-saving and efficiency-enhancing robot for 600MW generator units. Background Technology

[0002] The 600MW unit air-cooled energy-saving and efficiency-enhancing robot is an intelligent device applied to the air-cooled island of a 600MW thermal power unit. It is mainly used to solve the problems of cleaning the heat dissipation fins of the air-cooled island and improving energy efficiency. The robot system usually adopts Cartesian coordinate robot and mobile robot technology. Through the up-down and horizontal drive devices, the spray device moves horizontally on the surface of the heat dissipation fins to achieve "no dead angle" cleaning of the heat dissipation fins.

[0003] The existing 600MW unit air-cooled energy-saving and efficiency-enhancing robot uses an on-drive system. This robot effectively reduces back pressure in the air-cooled island and saves coal by automatically cleaning the heat sink fins. As the core component of the robot, the drive system's operational stability, control precision, and energy consumption directly determine the robot's working efficiency.

[0004] However, most air-cooled robots use a drive system consisting of a conventional motor and belt drive. While this method is simple in structure and low in cost, it is difficult to guarantee transmission accuracy. In actual operation, belt drives are prone to slippage and elasticity, causing the robot's trajectory to deviate, preventing it from performing cleaning operations along the preset path. This leaves cleaning dead zones on the heat sink fins, affecting the cleaning effect and the operating efficiency of the air-cooled island. Furthermore, in the harsh working environment of the air-cooled island—high temperature and dust—the guide structure is susceptible to dust and impurities, leading to accelerated wear and jamming. This not only affects the normal operation of the robot but also increases the frequency of equipment maintenance and repair costs, causing certain problems for the production and operation of power generation companies. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a 600MW unit air-cooled energy-saving and efficiency-enhancing robot drive device. It uses a sealing device to isolate dust and impurities, selects wear-resistant and high-temperature resistant materials to manufacture components, ensures the robot's running trajectory is accurate, can thoroughly clean the heat dissipation fins according to a preset path, eliminate cleaning dead corners, effectively reduce the back pressure of the air-cooled island, improve heat dissipation efficiency, save coal consumption, increase the economic benefits of power generation enterprises, reduce wear and jamming, and enhance the stability and reliability of the drive device and guide structure.

The toothed plate meshes with the spur gear, and the second motor drives the rotating shaft to rotate through the transmission assembly.

[0008] In one optional embodiment, the transmission assembly includes a first bevel gear fixedly connected to a rotating shaft and a second bevel gear fixedly connected to the output end of a second motor. The first bevel gear meshes with the second bevel gear, and a protective shell is located outside the first bevel gear and the second bevel gear to protect the first bevel gear and the second bevel gear.

[0009] In one optional embodiment, the protective assembly includes a protective plate fixedly connected to both sides of the second slide and a sealing gasket fixedly connected to one side of the protective plate. When the second slide moves, the sealing gasket pushes the impurities on the second guide rail to move.

[0010] In one optional embodiment, the lower moving component includes a first slide table slidably connected to a first guide rail, a first motor fixedly connected to the first slide table, and two sets of rollers rotatably connected to the first slide table.

[0011] In one optional embodiment, a through groove is provided on the first guide rail, and a roller is located in the through groove. When the roller rotates, it drives the first slide to move outside the first guide rail.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0021] Please refer to Figures 1-7A 600MW unit air-cooled energy-saving and efficiency-enhancing robot upper drive device includes air-cooled island heat dissipation fins 1; it also includes two sets of first guide rails 2 installed on the air-cooled island heat dissipation fins 1, a lower moving component installed on the first guide rails 2, air-cooled island heat dissipation fins 1 installed on the lower moving component, an upper moving component installed on the mounting frame 3, and a spray component installed on the upper moving component. The lower moving component is used to drive the mounting frame 3 to move, and the upper moving component is used to drive the spray component to move. The upper moving component includes a second guide rail 501 fixedly connected to the mounting bracket 3, a second slide 502 slidably connected to the second guide rail 501, a drive component mounted on the second slide 502 and the mounting bracket 3, and protective components mounted on both sides of the second slide 502. The drive component drives the second slide 502 to move on the second guide rail 501.

[0022] In a preferred embodiment of this utility model, when the lower moving component is activated, it drives the mounting bracket 3 to move along the first guide rail 2, thereby causing the upper moving component and the spray component to complete the first direction, such as "lateral" position adjustment; when the upper moving component is activated, it drives the second slide table 502 to move along the second guide rail 501 through the driving component, thereby causing the spray component to complete the second direction, such as "vertical" position adjustment; through the synergistic effect of the lower moving component and the upper moving component, the spray component is driven to move in two different directions, thereby achieving full-coverage spray cooling / cleaning of the air-cooled island heat dissipation fins 1, ultimately improving the heat dissipation efficiency of the air-cooled island and achieving the core purpose of energy saving and efficiency improvement of the air-cooling system.

[0023] In a preferred embodiment of this utility model, the drive assembly includes a toothed plate 503 fixedly connected to the mounting bracket 3, a rotating shaft 505 rotatably connected to the second slide 502, a spur gear 507 fixedly connected to one end of the rotating shaft 505, a second motor 508 fixedly connected to the lower end of the second guide rail 501, a transmission assembly mounted on the rotating shaft 505 and the second motor 508, and a protective shell 504 fixedly connected to the lower end of the second slide 502. The toothed plate 503 meshes with the spur gear 507. The second motor 508 drives the rotating shaft 505 to rotate through the transmission assembly. The second motor 508 transmits power to the rotating shaft 505 through the transmission assembly, causing the rotating shaft 505 to rotate around its own axis. The spur gear 507 fixed at one end of the rotating shaft 505 meshes with the toothed plate 503 fixed on the mounting bracket 3. When the spur gear 507 rotates, it rolls along the toothed plate 503, thereby driving the second slide 502 to slide smoothly along the second guide rail 501.

[0024] In a preferred embodiment of this utility model, the transmission assembly includes a first bevel gear 506 fixedly connected to the rotating shaft 505 and a second bevel gear 509 fixedly connected to the output end of the second motor 508. The first bevel gear 506 meshes with the second bevel gear 509. A protective shell 504 is located outside the first bevel gear 506 and the second bevel gear 509 to protect them. After the second motor 508 is started, it drives the second bevel gear 509 to rotate. The second bevel gear 509 drives the first bevel gear 506 to rotate through tooth surface meshing, converting the "axial power" output by the motor into the radial power of the rotating shaft 505.

[0025] Another embodiment based on the transmission component: Other structures from existing technologies can also be used, such as worm gears and worms. The worm gear replaces the first bevel gear 506 and is fixed to the rotating shaft 505, while the worm replaces the second bevel gear 509 and is fixed to the output end of the second motor 508. The worm gear and worm mesh with each other. The advantages are that the worm and worm gear work together to distribute the force more evenly, reduce wear, and the progressive meshing is impact-free, resulting in stronger overload resistance. The rated torque under the same module is about 1.2-1.5 times that of the bevel gear.

[0026] In a preferred embodiment of this utility model, the protective component includes a protective plate 510 fixedly connected to both sides of the second slide 502 and a sealing gasket 511 fixedly connected to one side of the protective plate 510. When the second slide 502 moves, the sealing gasket 511 pushes the impurities on the second guide rail 501 to move. When the second slide 502 moves along the second guide rail 501, the protective plate 510 moves synchronously with the second slide 502, causing the sealing gasket 511 to slide on the surface of the second guide rail 501. During the sliding process, the sealing gasket 511 pushes the impurities on the surface of the second guide rail 501 to both sides in the direction of slide movement, avoiding the accumulation of impurities at the contact point between the guide rail and the slide, and ensuring smooth movement of the slide.

[0027] In a preferred embodiment of this utility model, the lower moving component includes a first slide 401 slidably connected to the first guide rail 2, a first motor 402 fixedly connected to the first slide 401, and two sets of rollers 403 rotatably connected to the first slide 401. One set of rollers 403 is fixedly connected to the output end of the first motor 402. The first motor 402 is used to drive the rollers 403 to rotate. When the first motor 402 starts, it outputs rotational power to drive the rollers 403 fixed to it to rotate. The rotating rollers 403 form friction with the surface of the first guide rail 2, and the friction drives the first slide 401 to slide along the first guide rail 2. Since the mounting bracket 3 is fixed to the first slide 401, the mounting bracket 3 moves synchronously with the first slide 401, thereby driving the upper moving component and the spraying component to move.

[0028] In a preferred embodiment of this utility model, a through groove is provided on the first guide rail 2, and the roller 403 is located in the through groove. When the roller 403 rotates, it drives the first slide table 401 to move outside the first guide rail 2. The through groove of the first guide rail 2 limits the roller 403 to prevent the roller 403 from leaving the guide rail, and ensures that the first slide table 401 moves stably along the first guide rail 2, avoiding deviation or shaking.

[0029] In a preferred embodiment of this utility model, the spray assembly includes a fixed frame 601 fixedly connected to the second slide 502, a water supply pipe 602 fixedly connected to the fixed frame 601, a spray pipe 603 installed on the spray pipe 603, and an inlet pipe 604 installed on the water supply pipe 602. High-pressure water enters the water supply pipe 602 through the inlet pipe 604. The water supply pipe 602 serves as the main pipeline, distributing the medium evenly to each spray pipe 603 and spraying it onto the heat dissipation fins 1 of the air-cooled island below, thereby cooling or cleaning the fins. At the same time, the spray assembly moves with the second slide 502 and the first slide 401 to complete the spraying of all the fins.

[0030] In a preferred embodiment of this utility model, multiple sets of spray pipes 603 are provided, and the multiple sets of spray pipes 603 are symmetrically distributed on both sides of the water supply pipe 602 to expand the spray coverage of the spray assembly, avoid spray dead corners in the heat dissipation fins 1 of the air-cooled island, ensure that each area of ​​the fins can contact the medium, and improve the uniformity and efficiency of cooling or cleaning.

[0031] During operation, the first motor 402 is powered on and starts, outputting rotational power to directly drive a set of rollers 403 fixed to it to rotate. Since the rollers 403 are located within the through groove of the first guide rail 2, the through groove limits and prevents deviation. The rotating rollers 403 generate friction with the inner wall of the through groove, causing the first slide table 401 to slide smoothly along the first guide rail 2. The mounting bracket 3, fixed to the first slide table 401, moves synchronously, thereby carrying the upper moving component and the spraying component to complete a large-scale lateral movement, covering the lateral area of ​​the fins. The second motor 508 is fixed to the second guide rail 501. The lower end starts, driving the second bevel gear 509 at the output end to rotate. The second bevel gear 509 drives the first bevel gear 506 to rotate, and the first bevel gear 506 drives the rotating shaft 505 to rotate. The rotating shaft 505 drives the spur gear 507 at one end to rotate. The spur gear 507 meshes with the toothed plate 503 on the mounting bracket 3. When it rolls along the toothed plate 503, it drives the second slide table 502 to slide along the second guide rail 501. When the second slide table 502 moves, the sealing gaskets 511 on the two protective plates 510 and the first guide rail 501 rotate. The second guide rail 501 slides against the surface, pushing away impurities, dust, and fin debris on the guide rails to prevent jamming of the slide table. Finally, the second slide table 502 drives the spray assembly to complete a precise longitudinal movement, covering the longitudinal area of ​​the fins. High-pressure water enters the water supply pipe 602 through the water inlet pipe 604. The water supply pipe 602 serves as the main pipe, evenly distributing the medium to each spray pipe 603 and spraying it onto the heat dissipation fins 1 of the air-cooled island below, achieving cooling or cleaning of the fins. At the same time, the spray assembly moves with the second slide table 502 and the first slide table 401 to complete the spraying of all fins.

[0033] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
