Description

Technical Field

[0001] This utility model relates to the field of air-cooled island cleaning technology in cement plants, and in particular to a crawling fin cleaning robot for air-cooled islands. Background Technology

[0002] In the field of air-cooled island fin cleaning, traditional cleaning technologies have long faced the challenge of adapting to complex environments. As a key heat exchange device in thermal power plants, the core component of air-cooled islands, the fins, is typically arranged in a dense array with narrow gaps and an uneven surface, placing extremely high demands on the spatial accessibility and operational stability of the cleaning equipment. Traditional cleaning methods, such as manual cleaning, are not only inefficient and labor-intensive but also require operation in harsh environments such as high temperatures, posing serious safety hazards. Semi-automatic flushing devices are prone to shortening fin lifespan due to wear and tear on water pipes and cables, and cannot penetrate narrow gaps for thorough cleaning.

[0003] In the application of automated equipment, traditional wheeled and tracked robots are ill-suited to the special working conditions of fins: wheeled robots, due to their small contact area, are prone to slipping on smooth fin surfaces and lack sufficient turning flexibility, making it difficult to navigate precisely in narrow gaps; while tracked robots improve friction, their large overall structure makes them prone to mechanical interference with fins in dense fin arrays, leading to frequent jamming problems, and their obstacle-crossing ability is limited, unable to adapt to irregular protrusions and gap variations on the fin surface. These technical shortcomings make it difficult for existing automated equipment to achieve continuous and stable propulsion in narrow and complex fin environments, severely restricting the improvement of air-cooled island cleaning efficiency and equipment safety. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a crawling fin cleaning robot for air-cooled islands, comprising a crawling frame mechanism and a cleaning mechanism. The crawling frame mechanism includes an outer frame and an inner frame. Both ends of the inner frame are rotatably mounted with connecting shafts, and both ends of the connecting shafts are fixedly mounted with connecting rods. One end of each connecting rod is fixedly mounted with a short shaft, and multiple short shafts are rotatably connected to the outer frame. Multiple support legs (first type) are fixedly mounted at the lower end of the outer frame, and multiple support legs (second type) are fixedly mounted at the lower end of the inner frame. The cleaning mechanism is mounted on the inner frame and includes multiple wiping components. The cleaning mechanism can drive multiple wiping components to simultaneously clean the fins of the air-cooled island.

[0006] As a preferred embodiment of the air-cooled island crawling fin cleaning robot of this utility model, the cleaning mechanism includes a mounting frame, a dual-shaft extension asynchronous motor, and two cleaning kits. The mounting frame is fixedly mounted on the inner frame. The cleaning kit includes a main shaft and two auxiliary shafts. The main shaft and the two auxiliary shafts are rotatably mounted on the mounting frame in parallel. A bevel gear II and a main gear are fixedly mounted on the main shaft. A secondary gear is fixedly mounted on each of the two auxiliary shafts. The main gear meshes with both secondary gears. The dual-shaft extension asynchronous motor is fixedly mounted on the mounting frame. A bevel gear I is fixedly mounted on each of the two output ends of the dual-shaft extension asynchronous motor. Each bevel gear I meshes with a corresponding bevel gear II. A scrubbing assembly is installed at the lower end of the two auxiliary shafts.

[0007] As a preferred embodiment of the air-cooled island crawling fin cleaning robot of this utility model, the cleaning assembly includes a fixed plate, a cleaning wheel, multiple dampers and springs. The fixed plate is fixedly connected to the lower end of the sub-shaft, the cleaning wheel is disposed below the fixed plate, and the multiple dampers and springs are installed between the fixed plate and the cleaning wheel.

[0008] In a preferred embodiment of the air-cooled island crawling fin cleaning robot of this utility model, the length of the first support leg is greater than the length of the second support leg, and the length difference between the first support leg and the second support leg is less than the length of the connecting rod.

[0009] In a preferred embodiment of the air-cooled island crawling fin cleaning robot of this utility model, suction cups are fixedly installed at the lower ends of both the first and second support legs.

[0010] In a preferred embodiment of the air-cooled island crawling fin cleaning robot of this utility model, both the outer frame and the inner frame are rectangular hollow frames.

[0011] The beneficial effects of this utility model are:

[0012] 1. Relying on the crawling frame mechanism composed of an outer frame, an inner frame, connecting rods, connecting shafts, and support legs one and two, the connecting rods are rotated by a drive device to realize an insect-like crawling gait in which the outer frame and inner frame alternately lift and move forward. With the suction cups at the lower end of the support legs adhering to the fins, the problem of slippage and jamming in narrow gaps between fins of traditional wheeled or tracked robots is effectively avoided, ensuring that the robot can continuously and stably advance on the fin surface.

[0013] 2. In the cleaning mechanism, the dual-shaft asynchronous motor drives the main shaft to rotate through bevel gear one and bevel gear two, and then drives the secondary shaft to rotate synchronously through the meshing of the main gear and the auxiliary gear, so as to realize the coordinated operation of multiple scrubbing components; at the same time, a damper and a spring are provided between the fixed plate of the scrubbing component and the scrubbing wheel to ensure that the scrubbing wheel always fits in contact with the surface of the air-cooled island fins, avoiding scrubbing gaps caused by the alternating contact of the support legs, and improving the cleaning quality and uniformity.

[0014] 3. Both the outer and inner frames adopt a rectangular hollow frame structure, resulting in a lightweight overall design and significantly reducing energy consumption during the crawling operation. Furthermore, the movement of the crawling frame mechanism and the wiping action of the cleaning mechanism can be performed simultaneously, eliminating the need for staged operations. This ensures stable movement and reliable cleaning while greatly improving the overall cleaning efficiency of the air-cooled island fins. Attached Figure Description

[0024] Example

[0025] Reference Figures 1-4 This is the first embodiment of the present invention, which provides an air-cooled island crawling fin cleaning robot.

[0026] Specifically, to solve the above-mentioned technical problems, this utility model provides the following technical solution: a crawling fin cleaning robot for air-cooled islands, comprising a crawling frame mechanism 1 and a cleaning mechanism 2. The crawling frame mechanism 1 includes an outer frame 101 and an inner frame 102. Both ends of the inner frame 102 are rotatably mounted with connecting shafts 104. Both ends of the connecting shafts 104 are fixedly mounted with connecting rods 103. One end of each connecting rod 103 is fixedly mounted with a short shaft. Multiple short shafts are rotatably connected to the outer frame 101. Multiple support legs 105 are fixedly mounted at the lower end of the outer frame 101. Multiple support legs 206 are fixedly mounted at the lower end of the inner frame 102. The length of support legs 105 is greater than the length of support legs 206. The support legs 105 and 206 are connected... When the length difference is less than the length of the connecting rod 103, and the first support leg 105 and the second support leg 106 simultaneously contact the air-cooled island fins, the connecting rod 103 is in an inclined state. A drive device is installed on the outer frame 101 to drive the short shaft to rotate, which in turn drives the connecting rod 103 to rotate. This causes the outer frame 101 and the inner frame 102 to alternately lift and move forward, allowing the cleaning robot to crawl. The cleaning mechanism 2 is installed on the inner frame 102. The cleaning mechanism 2 includes multiple wiping components 209. The cleaning mechanism 2 can drive multiple wiping components 209 to simultaneously clean the air-cooled island fins, forming a crawling gait similar to that of an insect. This movement effectively avoids the problem of traditional wheeled or tracked robots slipping and getting stuck in narrow fin gaps, ensuring that the robot can continuously advance on the fin surface.

[0027] The cleaning mechanism 2 includes a mounting frame 201, a dual-shaft asynchronous motor 202, and two cleaning kits. The mounting frame 201 is fixedly mounted on the inner frame 102. Each cleaning kit includes a main shaft 204 and two auxiliary shafts 205. The main shaft 204 and the two auxiliary shafts 205 are rotatably mounted on the mounting frame 201. A bevel gear 206 and a main gear 207 are fixedly mounted on the main shaft 204. A secondary gear 208 is fixedly mounted on each of the two auxiliary shafts 205. The main gear 207 and the two auxiliary gears... All 208 are engaged. The dual-shaft extension asynchronous motor 202 is fixedly installed on the mounting bracket 201. Both output ends of the dual-shaft extension asynchronous motor 202 are fixedly installed with bevel gear 1 203. Each bevel gear 1 203 meshes with the corresponding bevel gear 206. The lower ends of the two secondary shafts 205 are equipped with a scrubbing assembly 209. The dual-shaft extension asynchronous motor 202 drives the main shaft 204 to rotate, and the main shaft 204 drives the two secondary shafts 205 to rotate, thereby driving the scrubbing assembly 209 to scrub the surface of the air-cooled island.

[0028] The scrubbing assembly 209 includes a fixed disk 2091, a scrubbing wheel 2092, multiple dampers 2093, and springs 2094. The fixed disk 2091 is fixedly connected to the lower end of the sub-shaft 205. The scrubbing wheel 2092 is located below the fixed disk 2091. The multiple dampers 2093 and springs 2094 are installed between the fixed disk 2091 and the scrubbing wheel 2092. When the first support leg 105 and the second support leg 106 simultaneously contact the surface of the air-cooled island fins, the scrubbing wheel 2092 is ensured to always be in contact with the surface of the air-cooled island, thus ensuring the quality of scrubbing.

[0029] Suction cups are fixedly installed at the lower ends of both support leg 105 and support leg 106 for adsorbing the fins of the air-cooled island.

[0030] Both the outer frame 101 and the inner frame 102 are rectangular hollow frames, which are lightweight and reduce energy consumption.

[0031] Working principle:

[0032] In its initial state, the suction cups of the lower support leg 105 of the outer frame 101 and the lower support leg 106 of the inner frame 102 are both attached to the air-cooled island fins. Because the length of support leg 105 is greater than that of support leg 106 and the difference in their lengths is less than the length of the connecting rod 103, the connecting rod 103 is tilted. Subsequently, the drive device on the outer frame 101 is activated, driving the short shaft fixed to one end of the connecting rod 103 to rotate. The short shaft drives the connecting rod 103 to rotate around the inner frame. The connecting shafts 104 at both ends of frame 102 rotate, causing the outer frame 101 and inner frame 102 to alternately complete the lifting and forward movement. When the connecting rod 103 lifts the outer frame 101, the suction cup of support leg 105 detaches from the fins and moves forward with the outer frame 101. After the outer frame 101 descends, the suction cup of support leg 105 re-attaches to the fins. Immediately afterwards, the connecting rod 103 lifts the inner frame 102, and the suction cup of support leg 2 106 detaches from the fins and moves forward with the inner frame 102. After the frame 102 descends, the suction cups of the second support leg 106 re-adhere to the fins, thus forming a crawling gait. The rectangular hollow structure of the outer frame 101 and the inner frame 102 reduces energy consumption due to its lightweight design. During the crawling process, the dual-shaft extension asynchronous motor 202 fixed on the mounting frame 201 on the inner frame 102 starts synchronously. The first bevel gear 203 at its output end meshes with the second bevel gear 206 on the main shaft 204 in the corresponding cleaning kit, driving the main shaft 204 to rotate. The main gear 207 on the main shaft 204 further meshes with the secondary gear 208 on the secondary shaft 205, driving the secondary shaft 205 to rotate. At the same time, the damper 2093 and spring 2094 between the fixed plate 2091 at the lower end of the secondary shaft 205 and the scrubbing wheel 2092 ensure that the scrubbing wheel 2092 always adheres to the fin surface. Finally, the secondary shaft 205 drives the scrubbing wheel 2092 to synchronously scrub the fins, realizing the coordinated work of continuous robot propulsion and efficient cleaning.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
