Description

Technical Field

[0001] This application belongs to the technical field of cooler cleaning and maintenance equipment, and particularly relates to a cooler cleaning device. Background Technology

[0002] Transformers are crucial equipment in nuclear power plant power supply systems, and their operational stability directly impacts the safety and reliability of the power supply. Coolers, as heat dissipation components of the transformer, effectively dissipate the heat generated during operation, ensuring the transformer's continuous and stable operation. However, the cooling fins of the cooler are constantly exposed, making them prone to accumulating dust, oil, and other impurities. This can clog heat dissipation channels, reduce heat dissipation efficiency, and easily lead to transformer overheating, performance degradation, and even equipment failure, significantly shortening the equipment's lifespan. Therefore, regular cleaning and maintenance of transformer coolers are essential.

[0003] For cleaning the coolers of large transformers in nuclear power plants, the industry mainstream cleaning method is still mainly manual cleaning due to the large overall height and complex structure of the heat dissipation fins. In actual operation, workers need to set up scaffolding in advance or use high-altitude work platforms, and use handheld high-pressure water guns to clean the heat dissipation fins of the cooler by spraying them in a close-range, straight-line manner.

[0004] However, the entire cleaning process involves high-altitude and high-risk operations. Workers are exposed to heights for extended periods, posing risks such as falls and personal injury. Manual work requires significant time for scaffolding erection and platform setup, and the slow, cumbersome operation process increases overall costs and may leave transformer equipment idle for extended periods, impacting the availability of nuclear power plant equipment and reducing operational efficiency. High-pressure water jets can only achieve simple linear spraying, while transformer cooler fins have complex, three-dimensional structures with numerous hidden areas such as sides and crevices. Linear water jets cannot effectively cover these blind spots, making it difficult to thoroughly clean the sides and crevices of the fins. This results in low cleaning coverage, significant dirt residue, and incomplete cleaning. Summary of the Invention

[0058] In some embodiments, the cooler cleaning device of this application can be used to clean large-sized coolers; in particular, the coolers of transformers in nuclear power plants, which are also known as radiators.

[0059] In some embodiments, the cooler includes a housing and heat dissipation fins disposed within the housing; the back of the housing has an opening to expose the heat dissipation fins and to facilitate the cooler cleaning device to clean the heat dissipation fins from the rear side.

[0060] like Figures 1-3As shown, in some embodiments, the cooler cleaning device 100 includes a mounting base 110, a walking mechanism 120, a cleaning mechanism 130, and a moving mechanism 140. The walking mechanism 120 includes a first walking component 121 and a second walking component 122 disposed on the mounting base 110 and used for walking on the cooler 200. The first walking component 121 and the second walking component 122 are spaced apart along a first direction, which is perpendicular to the walking direction of the first walking component 121. The cleaning mechanism 130 is located between the first walking component 121 and the second walking component 122. The cleaning mechanism 130 includes a cleaning mounting base 131, a rotation drive 132, a rotation mounting base 133, and a cleaning head 134 for spraying cleaning water and disposed on the rotation mounting base 133. The rotation drive 132 is disposed on the cleaning mounting base 131, and the output end of the rotation drive 132 is connected to the rotation mounting base 133 to drive the cleaning head 134 to swing. The moving mechanism 140 is connected to the mounting base 110 and the cleaning mounting base 131, and is used to drive the cleaning mounting base 131 to move back and forth along the first direction.

[0061] The mounting base 110 serves as the mounting carrier for the walking mechanism 120, the cleaning mechanism 130, and the moving mechanism 140, supporting each functional component and bearing the forces between them. The mounting base 110 can adopt a rod-type structure, a frame-type structure, a plate-beam combination structure, or a box-beam structure, which not only facilitates processing and manufacturing but also provides a stable mounting reference for the walking mechanism 120 and the moving mechanism 140, thus improving the overall structural rigidity of the device.

[0062] The traveling mechanism 120 is a component used to drive the cooler cleaning device 100 to move along the traveling direction on the back side 211 of the cooler 200.

[0063] The walking mechanism 120 includes a first walking component 121 and a second walking component 122. The first walking component 121 and the second walking component 122 are spaced apart at both ends of the mounting base 110 along a first direction, so that they are located on opposite sides of the back surface 211 of the cooler 200, spanning the opening on the back surface 211 of the cooler 200 to facilitate subsequent rinsing of the heat dissipation fins 220 through the opening. Both the first walking component 121 and the second walking component 122 can be of the type of wheeled walking structure, tracked walking structure, or magnetic crawling structure. Furthermore, the first walking component 121 and the second walking component 122 can be fixed to the mounting base 110 by bolt fastening, pin hinge connection, welding, or other methods.

[0064] The first direction can be a direction perpendicular to the travel direction of the first traveling component 121; for example, the travel direction of the first traveling component 121 can be found in [reference needed]. Figure 1 The Z-direction can also be referenced in the height direction of the cooler 200; the first direction can be referenced in... Figure 1The Y direction in the text can also be referred to in the width direction of the cooler 200; or, the travel direction of the first traveling component 121 can be referred to in the text. Figure 1 The Y direction in the text can also be referenced in the width direction of the cooler 200; the first direction can be referenced in... Figure 1 The Z-direction can also be referenced in the height direction of the cooler 200.

[0065] The cleaning mechanism 130 is a component used to spray cleaning water onto the heat dissipation fins 220 of the cooler 200 to achieve rinsing and decontamination, and it is located between the first travel assembly 121 and the second travel assembly 122.

[0066] The cleaning mechanism 130 includes a cleaning mounting base 131, a rotation drive component 132, a rotation mounting base 133, and a cleaning head 134. The cleaning mounting base 131 serves as the supporting foundation of the cleaning mechanism 130, used to mount the rotation drive component 132 and transmit the driving force of the moving mechanism 140. The rotation drive component 132 is fixed on the cleaning mounting base 131, and its output end is connected to the rotation mounting base 133 to provide power for the swing of the cleaning head 134. The rotation mounting base 133 is used to support the cleaning head 134 and can reciprocate with the output end of the rotation drive component 132, thereby driving the cleaning head 134 to swing synchronously. The cleaning head 134 is fixed on the rotation mounting base 133 and sprays cleaning water outward during operation to rinse and remove dirt from the heat dissipation fins 220 of the cooler 200.

[0067] In some examples, the rotating drive component 132 can be selected from types such as a swing cylinder, a servo swing motor, or a rotary cylinder, depending on the swing angle and torque requirements. The cleaning head 134 can be in the form of a high-pressure fan nozzle, a cylindrical nozzle, or a multi-hole nozzle, adaptable to different rinsing ranges and water pressure requirements. As the cleaning head 134 swings with the rotating mounting base 133, the sprayed water flow can change the rinsing angle, covering the front, side, and root areas of the heat sink fins 220.

[0068] When the output end of the rotating drive 132 drives the rotating mounting base 133 to reciprocate around the rotation axis, it in turn drives the cleaning head 134 mounted on the rotating mounting base 133 to swing synchronously, so that the water sprayed from the cleaning head 134 forms an inclined water flow on the surface of the heat sink fins 220 to clean the sides of the heat sink fins 220. The rotating mounting base 133 and the output end of the rotating drive 132 can be fixed by means of key connection, flange connection, set screw connection, etc. to ensure reliable transmission of rotational torque.

[0069] In some examples, the rotary drive 132 directly drives the rotary mounting base 133 to swing. That is, the output shaft of the rotary drive 132 is coaxially connected to the rotary mounting base 133, and the output shaft of the rotary drive 132 reciprocates at a set angle, thereby causing the rotary mounting base 133 and the cleaning head 134 to swing synchronously. This method has a compact structure and a short transmission chain, which is beneficial to improving the swing response speed and control accuracy.

[0070] In other examples, the rotary drive 132 indirectly drives the rotary mounting base 133 to swing through a transmission mechanism, which can be of the type of gear drive, synchronous belt drive, or linkage drive. The output end of the rotary drive 132 drives the rotary mounting base 133 to swing after being decelerated or reversed by the transmission mechanism. This method allows for adjustment of the swing angle range and swing speed as needed, making it highly adaptable.

[0071] The moving mechanism 140 is a component used to drive the cleaning mounting base 131 of the cleaning mechanism 130 to move back and forth between the first traveling assembly 121 and the second traveling assembly 122 along a first direction.

[0072] The power output end of the moving mechanism 140 is connected to the cleaning mounting base 131 of the cleaning mechanism 130. The moving mechanism 140 can drive the cleaning mounting base 131 to move back and forth along the first direction, thereby driving the entire cleaning mechanism 130 to move back and forth between the first traveling component 121 and the second traveling component 122, so that the cleaning head 134 can complete the sweeping operation along the first direction.

[0073] The moving mechanism 140 can adopt a rope traction structure, a lead screw drive structure, a gear and rack drive structure, etc., which can convert rotary motion or linear motion into linear reciprocating motion of the cleaning mounting base 131 along a first direction. The drive source of the moving mechanism 140 can be a servo motor, a stepper motor, a pneumatic motor, etc. Furthermore, the moving mechanism 140 can be fixed to the mounting base 110 or the traveling mechanism 120 by means of bolt connection, welding fixation, or slot positioning.

[0074] In this embodiment of the cooler cleaning device 100, when in use, the first walking component 121 and the second walking component 122 are respectively placed on both sides of the back 211 of the cooler 200, so that the cooler cleaning device 100 is horizontally mounted on the back 211 of the cooler 200; then, the walking mechanism 120 is activated, and the first walking component 121 and the second walking component 122 move along the side of the back 211 of the cooler 200 in the walking direction; the moving mechanism 140 is activated, and the cleaning mounting base 131 of the cleaning mechanism 130 drives the cleaning head 134 to move back and forth in the first direction, so that the cleaning head 134 completes the sweeping of the lateral range; the rotating drive component 132 is activated, and the rotating mounting base 133 and the cleaning head 134 swing back and forth, so that the cleaning water flow washes the heat dissipation fins 220 at multiple angles; finally, the walking mechanism 120 moves along the walking direction to the other end of the cooler 200, thus completing the cleaning operation of most areas of the cooler 200.

[0075] During this process, the vertical movement of the traveling mechanism 120 and the lateral movement of the moving mechanism 140 work together to allow the cleaning head 134 to cover most of the working area of ​​the cooler 200. For coolers 200 that are relatively high, high-level cleaning can be completed without the need for scaffolding or aerial work platforms, improving the safety of the cleaning operation. The cooler cleaning device 100 adopts a mechanized operation method, which can improve the work rhythm, shorten the overall work cycle, reduce labor maintenance costs, reduce the downtime of transformers waiting for maintenance, and help improve the operating efficiency of power supply equipment. The lateral reciprocating motion of the cleaning head 134, combined with its own oscillation, can adapt to the complex three-dimensional structure of the heat dissipation fins 220, covering more hidden areas, improving the cleaning coverage rate, and reducing dirt residue.

[0076] The first walking component 121 and the second walking component 122 can be respectively mounted on both sides of the cooler 200 along its width, which helps to improve the stability of the cooler cleaning device 100 during its movement after it is in place. The first walking component 121 and the second walking component 122 also help to reduce the size of the cooler cleaning device 100 along the walking direction, reduce the overall size of the cooler cleaning device 100, and make the cooler cleaning device 100 more adaptable to situations where the space behind the cooler 200 is small.

[0077] In some embodiments, the cooler cleaning device 100 includes a ground power and control system station. The ground power and control system station includes a water pump, a water tank, an electrical control cabinet, and a mobile vehicle equipped with wheels for easy movement. The water pump connects the water tank and the cleaning head 134, with the pump connected to the cleaning head 134 via a flexible hose to deliver high-pressure water. The ground power and control system station is connected to various mechanisms via electrical wires, which can be integrated with the flexible hoses to form a combined water and electricity pipeline. The ground power and control system station also includes an automatic hose reel device, on which the combined water and electricity pipeline is wound. This device automatically and synchronously reels and extends the combined water and electricity pipeline based on the real-time displacement of the cleaning head 134, reducing the possibility of tangling and excessive stress on the pipeline.

[0078] The electrical control cabinet is a functional component that coordinates the automated operation of all actuators in the cooler cleaning device 100. The cooler cleaning device 100 establishes signal interaction with each mechanism through wired or wireless transmission. The cooler cleaning device 100 can output control commands to the walking mechanism 120, the cleaning mechanism 130, and the moving mechanism 140, while receiving operating status feedback from each mechanism, coordinating the action sequence and operating parameters of each component, so that the cooler cleaning device 100 completes the entire cleaning operation according to preset logic.

[0079] In some examples, the electrical control cabinet may include a PLC controller, embedded industrial control module, microcontroller control unit, etc., which can be selected according to control accuracy, operational complexity, and on-site conditions. The control cabinet can be preset with multiple sets of operating parameters to correspond to different cooler sizes, levels of contamination, and cleaning requirements. The control cabinet can also interface with position detection elements, water pressure detection elements, stroke detection elements, etc., to collect data information in real time during operation, dynamically adjust the operating status of each mechanism, and adapt to changes in on-site conditions.

[0080] In some examples, the control cabinet includes an industrial computer (host computer) and a programmable logic controller (PLC) to centrally process sensor signals and control all actuators.

[0081] The ground power and control system station provides the entire system with high-pressure cleaning water and electricity, houses the transmission pipelines, and serves as the control center.

[0082] The automatic coordinated operation of the walking mechanism 120, cleaning mechanism 130, and moving mechanism 140 via the electrical control cabinet reduces the need for manual on-site operation, further minimizing personnel involvement in high-altitude work scenarios and improving operational safety. The electrical control cabinet precisely matches the movement rhythm of each mechanism, ensuring that the lateral movement and swinging motion of the cleaning head 134 are coordinated with the overall vertical movement of the device, improving the uniformity and efficiency of the cleaning operation and enhancing the consistency of cleaning results across different work areas.

[0083] like Figures 1-3As shown, in some embodiments, the mounting base 110 includes a telescopic component 111, which is a component for adjusting the distance between the first walking component 121 and the second walking component 122. The two ends of the telescopic component 111 along the first direction are respectively connected to the first walking component 121 and the second walking component 122.

[0084] The telescopic component 111 is used to adjust the distance between the first traveling component 121 and the second traveling component 122. The telescopic component 111 is arranged along a first direction, and its two ends are connected to the first traveling component 121 and the second traveling component 122, respectively. By changing its own length, the telescopic component 111 can move the first traveling component 121 and the second traveling component 122 closer or further apart along the first direction, thereby changing the distance between them.

[0085] The telescopic assembly 111 can be selected from types such as sleeve-type telescopic rod, scissor-type telescopic frame, and sliding rail type telescopic beam.

[0086] For example, the telescopic assembly 111 is a sleeve-type telescopic rod, and the telescopic rod 112 is composed of multiple sections of tubing nested inside and outside. The length is adjusted by the relative sliding between the tubing sections. The structure is simple and the adjustment is convenient.

[0087] By adjusting the distance between the first traveling component 121 and the second traveling component 122 through the telescopic component 111, the cooler cleaning device 100 can be adapted to coolers 200 of different widths, meeting the cleaning needs of coolers 200 of varying widths. For coolers 200 of different specifications, the telescopic component 111 can be pre-adjusted according to the width of the cooler 200, thus broadening the applicable scenarios of the cooler cleaning device 100.

[0088] like Figures 1-3 As shown, in some embodiments, the telescopic component 111 is a telescopic rod 112, and the two ends of the telescopic rod 112 are respectively connected to the first walking component 121 and the second walking component 122.

[0089] Telescopic rod 112 is a telescopic component that uses a sliding rod structure to achieve length adjustment.

[0090] In some examples, the telescopic rod 112 includes multiple coaxially nested rods arranged along a first direction. Each rod segment can slide relative to the other along the axial direction to change its overall length, thereby causing the first walking component 121 and the second walking component 122 connected at both ends to move closer or further apart along the first direction, thus adjusting the distance between them.

[0091] The two ends of the telescopic pole 112 can be fixed to the first traveling assembly 121 and the second traveling assembly 122 by means of bolt connection, pin connection, flange connection, etc., which helps to improve the stability of the structural connection and the uniformity of force transmission.

[0092] The telescopic pole 112 can be made of various cross-sections, such as circular, square, or polygonal. The material for the telescopic pole 112 can be aluminum alloy, stainless steel, or carbon fiber composite material.

[0093] For example, the telescopic pole 112 is an aluminum alloy telescopic pole with a circular cross-section. The telescopic pole 112 is lightweight and corrosion resistant, and the circular cross-section is subjected to uniform force in the circumferential direction, which is beneficial to improving the bending stiffness of the telescopic pole 112.

[0094] By setting the telescopic component 111 as the telescopic rod 112, the telescopic rod 112 has a simple structure, fewer components, and lower processing, manufacturing and assembly difficulty, which can control the production and assembly costs of the components; the rod-shaped structure occupies little space, which is convenient to arrange on the cooler cleaning device 100, and can stably support the walking mechanism 120 and the cleaning mechanism 130, improving the smoothness of operation during the spacing adjustment process.

[0095] The cooler cleaning device 100 of this application embodiment adopts the cooperation of a first walking component 121, a second walking component 122, a telescopic rod 112 and a cleaning mechanism 130. Its structure is simple and its size is small, which makes the cooler cleaning device 100 not only able to be stably attached to the vertical wall and perform precise two-dimensional planar movement, but also automatically adapt to the width of different coolers 200 and complete full-coverage cleaning in narrow spaces.

[0096] like Figures 4-8 As shown, in some embodiments, the telescopic rod 112 includes a first connecting rod 1121, a second connecting rod 1122, and a locking member. One end of the first connecting rod 1121 is connected to the first walking assembly 121, one end of the second connecting rod 1122 is connected to the second walking assembly 122, and the other end of the first connecting rod 1121 is slidably connected to the other end of the second connecting rod 1122 and locked by the locking member, so that the length of the telescopic rod 112 is adjustable.

[0097] The first connecting rod 1121 and the second connecting rod 1122 are the main load-bearing segments of the telescopic rod 112. They are coaxially arranged along the first direction and form a relatively sliding connection through the mating structure at their ends. During the relative sliding process, the overall length of the telescopic rod 112 can be changed, thereby causing the first traveling component 121 and the second traveling component 122 at both ends to move closer or further apart along the first direction, thus adjusting the distance between the first traveling component 121 and the second traveling component 122. The outer end of the first connecting rod 1121 is connected to the first traveling component 121, and the outer end of the second connecting rod 1122 is connected to the second traveling component 122. The relative linear sliding between the first connecting rod 1121 and the second connecting rod 1122 can be directly transmitted to the first traveling component 121 and the second traveling component 122, realizing the adjustment of the distance between the first traveling component 121 and the second traveling component 122.

[0098] The locking component is used to lock the relative positions of the first traveling assembly 121 and the second traveling assembly 122, and is disposed at the sliding engagement part of the first connecting rod 1121 and the second connecting rod 1122. When the telescopic rod 112 is adjusted to the target length that matches the width of the cooler 200, the locking component can restrict the relative sliding of the first connecting rod 1121 and the second connecting rod 1122, keeping the length of the telescopic rod 112 fixed. This ensures that the distance between the first traveling assembly 121 and the second traveling assembly 122 is stable during the travel operation of the cooler cleaning device 100, maintaining the overall operating posture and force balance of the cooler cleaning device 100.

[0099] The locking components can adopt structural forms such as set screw locking, positioning pin locking, and snap-locking, and can be selected according to the locking force requirements and the ease of operation requirements.

[0100] The telescopic rod 112 adopts a structure with sliding engagement of the first connecting rod 1121 and the second connecting rod 1122 plus a locking component. The structure is simple, with few components, and the processing and assembly procedures are simple, which can control the production and assembly costs of the components. The sliding adjustment operation of the first connecting rod 1121 and the second connecting rod 1122 is intuitive, and the locking operation is convenient. It is easy for on-site operators to quickly complete the spacing adjustment and fixation according to the width specifications of the cooler 200, thereby improving the adaptation efficiency of the cooler cleaning device 100.

[0101] like Figures 4-8As shown, in some embodiments, the first connecting rod 1121 includes a first rod portion 11211, a first locking portion 11212, and a plurality of first sliding portions 11213. The two ends of the first rod portion 11211 are respectively connected to the first walking component 121 and the plurality of first sliding portions 11213. The plurality of first sliding portions 11213 are arranged at intervals along the circumference of the first rod portion 11211, and a first sliding groove 11214 is formed between two adjacent first sliding portions 11213. The first locking portion 11212 is connected to the end of the plurality of first sliding portions 11213 facing away from the first rod portion 11211. The second connecting rod 1122 includes a second rod portion 11221, a second locking portion 11222, and a plurality of second sliding portions 11223. The two ends of the second rod portion 11221 are respectively connected to the second traveling assembly 122 and the plurality of second sliding portions 11223. The plurality of second sliding portions 11223 are spaced apart circumferentially along the second rod portion 11221, and a second sliding groove 11224 is formed between adjacent two second sliding portions 11223. The second locking portion 11222 is connected to the ends of the plurality of second sliding portions 11223 facing away from the second rod portion 11221. Each second sliding portion 11223 is inserted into a corresponding first sliding groove 11214, with the first locking portion 11212 located inside the plurality of second sliding portions 11223. Each first sliding portion 11213 is inserted into a corresponding second sliding groove 11224, with the second locking portion 11222 located inside the plurality of first sliding portions 11213. The first sliding part 11213 and the second sliding part 11223 are nested together to form a multi-level overlapping mating structure. The locking member includes a first locking member and a second locking member. The first locking member locks the first locking part 11212 and the second sliding part 11223, and the second locking member locks the second locking part 11222 and the first sliding part 11213.

[0102] The first rod portion 11211 is the section connecting the first connecting rod 1121 and the first traveling assembly 121, and extends along a first direction. One end of the first rod portion 11211 facing the second connecting rod 1122 is connected to a plurality of first sliding portions 11213. The plurality of first sliding portions 11213 are arranged circumferentially spaced along the first rod portion 11211, extending from the end of the first rod portion 11211 towards the second connecting rod 1122. The space between two adjacent first sliding portions 11213 forms a first sliding groove 11214, and the first sliding groove 11214 and the second sliding portion 11223 form a fitted sliding relationship. The first sliding groove 11214 provides space for the corresponding sliding structure of the second connecting rod 1122 to slide.

[0103] The second rod portion 11221 is the section connecting the second connecting rod 1122 and the second traveling assembly 122. The second rod portion 11221 extends along a first direction, and one end of the second rod portion 11221 facing the first connecting rod 1121 is connected to a plurality of second sliding portions 11223. The plurality of second sliding portions 11223 are arranged circumferentially spaced along the second rod portion 11221, extending from the end of the second rod portion 11221 towards one side of the first connecting rod 1121. The space between two adjacent second sliding portions 11223 forms a second sliding groove 11224, which engages with the first sliding portion 11213 in a sliding fit. The second sliding groove 11224 provides space for the corresponding sliding structure of the first connecting rod 1121 to slide.

[0104] The first sliding part 11213 and the second sliding part 11223 adopt a circumferentially staggered fitting form. The second sliding part 11223 is correspondingly embedded in the first sliding groove 11214, and the first sliding part 11213 is correspondingly embedded in the second sliding groove 11224. The two form a mutually guiding sliding fit structure along the first direction. During the sliding process, the contact surface is evenly distributed, and the movement is smooth. The first locking part 11212 is connected to the ends of all the first sliding parts 11213 that are away from the first rod part 11211, and can connect all the first sliding parts 11213, improving the structural reliability of the first connecting rod 1121. In addition, the second locking part 11222 is connected to the ends of all the second sliding parts 11223 that are away from the second rod part 11221, and can connect all the second sliding parts 11223, improving the structural reliability of the second connecting rod 1122. In addition, the first locking part 11212 is connected to the ends of all the second sliding parts 11223 that are away from the second rod part 11221, and can connect all the second sliding parts 11223, improving the structural reliability of the second connecting rod 1122. 1212 is located in the inner space enclosed by all the second sliding parts 11223, and the second locking part 11222 is located in the inner space enclosed by all the first sliding parts 11213. The first locking part 11212 and the second locking part 11222 are opposite to each other and can form an axial limit on the inward sliding stroke of the first sliding part 11213 and the second sliding part 11223. Together, they limit the maximum length of the telescopic rod 112 and prevent the first connecting rod 1121 and the second connecting rod 1122 from sliding out.

[0105] The locking mechanism includes a first locking member and a second locking member. The first locking member is engaged with the connection position between the first locking part 11212 and the second sliding part 11223, fixing their relative axial positions after locking. The second locking member is engaged with the connection position between the second locking part 11222 and the first sliding part 11213, fixing their relative axial positions after locking. The two locking structures work simultaneously, forming constraints in the two engagement areas of the telescopic rod 112, improving the uniformity of force distribution and overall rigidity of the structure after locking.

[0106] When the telescopic rod 112 is adjusted to the target length and locked by the first and second locking components, the circumferentially staggered structure of the first sliding part 11213 and the second sliding part 11223 is rigidly fixed, and there is no relative sliding allowance between the first sliding part 11213 and the second sliding part 11223. The telescopic rod 112 transforms from a telescopic movable assembly into a rigid, integral box beam structure. The cross-section of this box beam structure is enclosed by multiple circumferentially distributed first sliding parts 11213 and second sliding parts 11223 to form a closed or nearly closed cross-sectional profile. The moment of inertia of the cross-section is much greater than that of a single solid circular rod or a single tubular rod. When subjected to a lateral load perpendicular to the axial direction of the telescopic rod 112, the first sliding parts 11213 and the second sliding parts 11223 at the upper and lower edges of the cross-section bear tensile stress and compressive stress, respectively. The material distribution is far from the center position, which can effectively resist lateral bending deformation. Simultaneously, the first and second locking members apply a pre-tightening pressure to the first sliding part 11213 and the second sliding part 11223 radially, causing positive pressure and static friction to be generated on the mating contact surfaces of the first sliding part 11213 and the second sliding part 11223. The load can be evenly transmitted between the first sliding part 11213 and the second sliding part 11223 through the contact surface, avoiding local stress concentration and further improving the bending stiffness of the overall structure. The box beam structure has high lateral bending stiffness, which can stably bear the eccentric load and dynamic load generated during the movement of the cleaning mechanism 130 along the telescopic rod 112, reducing the deflection and vibration of the telescopic rod 112. This is beneficial for supporting the smooth operation of the cleaning head 134 and improving the movement accuracy and spray position accuracy of the cleaning head 134 during the cleaning operation.

[0107] By controlling the first sliding part 11213 and the second sliding part 11223 to slide symmetrically in opposite directions, the total length of the telescopic rod 112 can be continuously adjusted to adapt to the cleaning needs of coolers 200 of different widths. This locked state makes the telescopic rod 112 a rigid box beam structure with high lateral bending stiffness, which can stably bear the operating load of the cleaning mechanism 130, which is conducive to supporting the smooth operation of the cleaning head 134 and improving the movement accuracy of the cleaning head 134 during the cleaning operation.

[0108] like Figure 7 and Figure 8 As shown, in some embodiments, the first locking portion 11212 is provided with a first threaded through hole 11215, which penetrates the first locking portion 11212 radially along the first rod portion 11211, and the first locking member is threadedly connected to the first threaded through hole 11215; the second locking portion 11222 is provided with a second threaded through hole 11225, which penetrates the second locking portion 11222 radially along the second rod portion 11221, and the second locking member is threadedly connected to the second threaded through hole 11225.

[0109] A first threaded through hole 11215 is formed in the first locking portion 11212 and extends radially through the first rod portion 11211. The inner wall of the hole is machined with an internal thread structure that matches the first locking member. The first locking member can be screwed in or out radially along the first rod portion 11211 by threading into the first threaded through hole 11215. In the screwed-in state, the inner end of the first locking member can press against the side wall of the second sliding portion 11223, and the axial sliding of the second sliding portion 11223 is restricted by the friction of the contact surface, thereby fixing the relative position of the first locking portion 11212 and the second sliding portion 11223.

[0110] The second threaded through hole 11225 is formed in the second locking part 11222 and is arranged radially through the second rod part 11221. The inner wall of the hole is machined with an internal thread structure adapted to the second locking member. The second locking member can be screwed in or out radially along the second rod part 11221 by threading into the second threaded through hole 11225. In the screwed-in state, the inner end of the second locking member can press against the side wall of the first sliding part 11213, and the axial sliding of the first sliding part 11213 is restricted by the friction of the contact surface, so as to fix the relative position of the second locking part 11222 and the first sliding part 11213.

[0111] This threaded adjustment structure has no gear limitations, allowing for continuous, stepless adjustment of the total length of the telescopic rod 112, precisely adapting to the width dimensions of different coolers 200. Once adjusted, this threaded friction locking mechanism rigidly fixes the first sliding part 11213 and the second sliding part 11223, ensuring the overall stability of the telescopic rod 112 under load and during movement. The continuously adjustable and rigidly locked length of the telescopic rod 112 allows the cooler cleaning device 100 to adapt to all coolers 200 of varying widths within a certain range, enabling flexible deployment. This mechanical locking structure ensures the rigidity and stability of the long telescopic rod 112 during movement, reduces vibration during operation, and improves the overall reliability of the device.

[0112] like Figure 3 As shown, in some embodiments, the cleaning mounting base 131 is provided with a guide hole 1312, and the telescopic rod 112 slides through the guide hole 1312.

[0113] A guide hole 1312 is formed on the cleaning mounting base 131, extending through the cleaning mounting base 131 along the first direction. The contour of the inner wall of the hole matches the contour of the outer wall of the telescopic rod 112, forming a sliding fit interface between the cleaning mounting base 131 and the telescopic rod 112. The cleaning mounting base 131 is sleeved on the outside of the telescopic rod 112 through the guide hole 1312, and can reciprocate along the axial direction of the telescopic rod 112 under the drive of the moving mechanism 140. The telescopic rod 112 can provide guidance and constraint for the movement of the cleaning mounting base 131, limiting the movement path of the cleaning mounting base 131 to extend along the first direction and constraining the radial offset of the cleaning mounting base 131 during its movement.

[0114] The cross-sectional shape of the guide hole 1312 can be adapted to the cross-sectional shape of the telescopic rod 112, and can be in the form of a circular hole, a square hole, a polygonal hole, etc. The inner wall of the guide hole 1312 can be provided with self-lubricating bushings, linear bearings, copper sleeves, and other guiding elements to reduce sliding friction resistance.

[0115] For example, the cleaning mounting base 131 is provided with a slider 1311, and the telescopic rod 112 can be used as a sliding rod. The sliding rod passes through the slider 1311, and the inner hole of the slider 1311 forms a guide hole 1312. Through the cooperation of the slider 1311 and the sliding rod, the frictional resistance is small and the movement is smooth when the cleaning mounting base 131 moves along the telescopic rod 112.

[0116] The telescopic rod 112 is used directly as a guide rod, eliminating the need for additional independent guide rods. This reduces the number of parts in the cooler cleaning device 100, simplifies the overall structure, and lowers production, assembly, and maintenance costs. Furthermore, the circumferentially staggered structure of the first sliding part 11213 and the second sliding part 11223 ensures that the overall outer diameter of the telescopic rod 112 remains constant during length adjustment. The clearance between the guide hole 1312 and the outer wall of the telescopic rod 112 remains stable, providing better guidance and improving the stability and accuracy of the movement of the cleaning head 134 driven by the cleaning mounting base 131.

[0117] In some embodiments, the number of telescopic rods 112 is one or more, and the multiple telescopic rods 112 are distributed at intervals along the traveling direction of the first traveling assembly 121 to improve the operational reliability of the cleaning mechanism 130 and the structural reliability of the cooler cleaning device 100. For example, the number of telescopic rods 112 is two, and the two telescopic rods 112 are arranged along the traveling direction of the first traveling assembly 121.

[0118] like Figure 9As shown, in some embodiments, the telescopic rod 112 can be replaced by a fixed rod 113 with a non-adjustable length. The fixed rod 113 has a simple structure and does not require segmented design. The overall structure has higher rigidity, the processing and assembly process is simpler, and the manufacturing cost is lower. It is suitable for operation scenarios where the width specification of the cooler 200 is uniform and there is no need to adapt to multiple width sizes.

[0119] In some embodiments, the fixing rod 113 is provided with a groove, and the slider 1311 of the cleaning mounting base 131 is inserted into the groove to reduce the moving resistance of the cleaning mounting base 131.

[0120] like Figure 10 As shown, in some embodiments, the cleaning mechanism 130 further includes a rotating rod 135 extending along a second direction. The rotating rod 135 is rotatably mounted on the cleaning mounting base 131, and the rotating mounting base 133 is connected to the rotating rod 135. There are multiple cleaning heads 134, which are spaced apart along the second direction on the rotating mounting base 133. The output end of the rotation drive member 132 is connected to the end of the rotating rod 135 to drive the rotating rod 135 to rotate around its own axis. The second direction is the walking direction of the first walking assembly 121.

[0121] The rotating rod 135 is a rod that supports the rotating mounting base 133 and transmits the oscillating rotational force, extending along the second direction. The rotating rod 135 is rotatably assembled onto the cleaning mounting base 131 via a bearing-type rotating pair structure, and can reciprocate around its own axis. The rod body of the rotating rod 135 is fixedly connected to the rotating mounting base 133. During rotation, it can drive the rotating mounting base 133 to swing synchronously around the rod body axis, thereby driving all cleaning heads 134 to synchronously adjust the spray angle.

[0122] Multiple cleaning heads 134 are arranged at intervals along the second direction on the rotating mounting base 133 and can rotate synchronously with the rotating mounting base 133. The synchronous operation of multiple sets of cleaning heads 134 arranged along the second direction can expand the coverage of a single operation in the second direction and increase the cleaning area per unit time.

[0123] The output end of the rotating drive component 132 is connected to the end of the rotating rod 135, directly driving the rotating rod 135 to rotate around its own axis. The power transmission path is direct, and the swing angle and reciprocating frequency of the rotating rod 135 can be precisely controlled to adapt to different cleaning conditions.

[0124] The moving mechanism 140 drives the cleaning head 134 to move along the first direction, and the rotating drive 132 drives the cleaning head 134 to swing in the first direction. The combination of these two movements makes the rinsing path formed by the water flow sprayed from the cleaning head 134 on the surface of the heat sink fins 220 not a simple straight line or fan shape, but a two-dimensional planar coverage area composed of dense sine waves or sawtooth waves, which is beneficial to improve the cleaning effect and reduce cleaning blind spots.

[0125] like Figure 10 As shown, in some embodiments, the rotating mounting base 133 includes a water pipe 1331 extending along a second direction. Each water pipe 1331 is provided with multiple cleaning heads 134 spaced apart along the second direction. The internal cavity of the water pipe 1331 forms a channel for conveying cleaning water. Multiple cleaning heads 134 are spaced apart on the pipe body along the second direction. Cleaning water can be directly conveyed to each cleaning head 134 through the cavity and sprayed outward. Cleaning water can be conveyed from the internal channel of the rotating mounting base 133 to each cleaning head 134, thereby eliminating the need for external water supply hoses, making the structure more compact, and reducing the problems of entanglement and interference caused by external pipelines during swinging operation, thus improving the reliability and smoothness of the swinging operation of the cleaning mechanism 130. The number of water pipes 1331 is one or more, and the multiple water pipes 1331 are spaced apart along the first direction to increase the cleaning area of ​​the cleaning mechanism 130 and improve the cleaning efficiency.

[0126] like Figure 10 As shown, in some embodiments, the cleaning mechanism 130 also includes a camera 136 disposed on a rotating mounting base 133, the camera 136 being positioned toward the cooler 200.

[0127] The camera 136 is a component used to collect image information of the surface of the heat dissipation fins 220 of the cooler 200, and can obtain the distribution of dirt and the cleaning status of the cleaning area in real time.

[0128] The camera 136 can be mounted on the rotating mounting base 133 by means of bolt connection, snap-fit ​​fixing, adhesive fixing, etc. The camera 136 can be of the type of industrial waterproof camera, wide-angle camera, high-definition network camera, etc.

[0129] For example, camera 136 is an industrial waterproof camera 136, which is waterproof and dustproof, can work stably in high-pressure water spray environment, and is equipped with LED fill light to obtain clear images in low light environment.

[0130] By setting a camera 136 facing the cooler 200 on the rotating mounting base 133, visual feedback is introduced, making the cleaning process more targeted rather than blindly covering. While ensuring overall efficiency, the camera 136 can focus on tackling stubborn stains based on the image information collected, ensuring that the cleaning quality meets the standards.

[0131] like Figure 10 As shown, in some embodiments, the cleaning mechanism 130 further includes an air nozzle 137 disposed on the rotating mounting base 133, with the air outlet of the air nozzle 137 facing the camera 136.

[0132] The nozzle 137 is a component used to spray compressed gas onto the lens surface of the camera 136 to remove water mist and droplets.

[0133] The air nozzle 137 can be mounted on the rotating mounting base 133 by means of threaded connection, snap-fit ​​fixing, welding fixing, etc. The air nozzle 137 can be of the type of conical nozzle, fan nozzle, annular air curtain nozzle, etc. The air source of the air nozzle 137 can come from an external compressed air pipeline, an internal air pump, an air storage tank, etc.

[0134] By setting the air nozzle 137 with the air outlet facing the camera 136, compressed gas can be used to remove water mist and water droplets adhering to the lens surface of the camera 136 in a timely manner, keeping the lens field of view clear and ensuring that the camera 136 can continuously obtain clear images of the surface of the cooler 200, which is beneficial to the stable operation of the visual feedback system.

[0135] In some embodiments, when using the cooler cleaning device 100, the width parameter of the cooler 200 is first acquired and the locking of the telescopic structure is released. During operation, the cooler cleaning device 100 is pushed to the back 211 of the cooler 200, and the actual width W of the cooler 200 can be obtained by a handheld rangefinder or the ultrasonic sensor built into the device. For example, the width adaptation range can cover 1500-1800mm; then the first locking member and the second locking member are released to release the position constraint on the telescopic rod 112.

[0136] Pull the telescopic rods 112 on both sides to move synchronously in opposite directions. For example, the first connecting rod 1121 includes one first rod part 11211 and three first sliding parts 11213, and the second connecting rod 1122 includes one second rod part 11221 and three second sliding parts 11223. By pulling the first sliding parts 11213 and the second sliding parts 11223, the telescopic amount can be adjusted so that the total length L of the entire telescopic rod 112 is slightly larger than the actual width W of the cooler 200. For example, an assembly allowance of about 50mm can be reserved to facilitate subsequent alignment and installation.

[0137] Bring the cooler cleaning device 100 close to the cooler 200, aligning both ends of the telescopic rod 112 with the side frames of the cooler 200. Then, simultaneously tighten all the first and second locking parts. During the screwing process, the first and second locking parts forcefully press against the specially designed grooves or planes of the first sliding part 11213 and the second sliding part 11223, generating significant static friction. Simultaneously, the first and second locking parts 11212 and 11222 respectively clamp the three first sliding parts 11213 and the three second sliding parts 11223, restricting radial movement of the first and second sliding parts 11213 and 11223. For example, after locking, the matching error between the length L of the telescopic rod 112 and the width W of the cooler 200 can be controlled within ±5mm, achieving high fitting accuracy.

[0138] The horizontal scanning speed Vx can be preset, for example, the value range can be 0.05-0.2m / s; the swing angle θ of the cleaning head 134 can be set, for example, the value range can be ±60°; the swing frequency f can be set, for example, the value range can be 0.5-2Hz; the cleaning head 134 is connected to the water pump, and the water pump supplies water to the cleaning head 134; the water pump is started to stabilize the water pressure at the preset value P, for example, the value range can be 3-5 bar, to provide a stable water source for the cleaning operation.

[0139] The PLC controller synchronously operates two independent threads: the lateral translation and the oscillation of the cleaning head 134. Lateral translational motion: The control moving mechanism 140 pulls the cleaning head 134 to make a uniform reciprocating linear motion Vx along the telescopic rod 112. The moving stroke is determined by the limit sensors at both ends of the telescopic rod 112.

[0140] The cleaning head 134 oscillates: the rotating drive 132 drives the rotating rod 135 to rotate, realizing the reciprocating rotation of the cleaning head 134. In the initial state, the cleaning head 134 of the cleaning mechanism 130 is in a horizontal state perpendicular to the back 211 of the cooler 200, and the water jet direction is concentrated on the heat dissipation area of ​​the cooler 200, completing the initial cleaning of the core area; after entering the rotation state, the output torque of the rotating drive 132 drives the rotating rod 135 to rotate, and the cleaning head 134 rotates synchronously with the rotating rod 135, so that the spray direction is aligned with the side area of ​​the cooler 200; after cleaning one side area, the rotating rod 135 drives the cleaning head 134 to rotate back to the initial position, and then rotates to the other side, repeating the rotation cleaning process, corresponding to the reciprocating oscillation operation of the cleaning head 134.

[0141] The combination of the lateral translation and the oscillation of the cleaning head 134 results in a rinsing path formed by the water flow on the surface of the heat sink fins 220 that is not a simple straight line or fan shape, but a two-dimensional planar coverage area composed of dense sine waves or sawtooth waves. By optimizing the ratio of the lateral scanning speed Vx to the oscillation frequency f, the rinsing overlap rate of the water flow on any vertical stripe of the heat sink fins 220 can be greater than 30%, reducing cleaning blind spots and improving cleaning uniformity.

[0142] During the movement and rinsing of the cleaning head 134, the camera 136 continuously captures close-up images of the surface of the heat sink 220 at a fixed frame rate, for example, the frame rate can be 10fps; the air nozzle 137 periodically sprays compressed air to remove water mist adhering to the lens and improve the clarity of the image acquisition.

[0143] The acquired images are transmitted to the industrial control computer in real time and analyzed by image processing algorithms: First, the images are preprocessed by grayscale conversion, contrast enhancement, and region of interest (ROI) extraction; then, features such as grayscale mean and standard deviation of local areas are extracted, or a trained lightweight convolutional neural network model is used to determine whether there are stains such as sludge, dust, and scale in the area; finally, the cleanliness score of the current field of view center area and the coordinates of the stain bounding box are output, with the cleanliness score ranging from 0 to 100.

[0144] The industrial control computer includes a dynamic cleaning strategy adjustment mechanism. This mechanism uses closed-loop feedback based on detection results to dynamically adjust cleaning parameters. The control system has a preset cleanliness threshold, which can be set according to cleaning requirements, such as 85 points, corresponding to two operating modes. Normal cleaning mode: If the cleanliness score of the current area is greater than or equal to the threshold, the system maintains the current horizontal scanning speed, oscillation frequency, and water pressure parameters unchanged, and continues to operate along the predetermined path.

[0145] Targeted Enhancement Mode: If the current area's cleanliness score is less than the threshold, the control system immediately records the coordinates of the current stain location. When the cleaning head 134 moves to the stain's coordinates, it automatically executes at least one enhancement operation: reducing the lateral speed to 1 / 3 of its original value, extending the rinsing time; increasing the swing angle of the cleaning head 134 to ±75°, covering a wider side area; instantly increasing the water pressure by 1-2 bar via bus communication command to the power flushing station, lasting for 2-3 seconds, enhancing the flushing force; and performing short-distance round-trip supplementary cleaning near the coordinate point. After completing the enhanced cleaning, the system restores its original operating parameters and continues operation.

[0146] The industrial control computer follows a zigzag path planning algorithm to complete a full lateral scan and inspection cleaning process at a fixed height on the cooler 200, using either a single-pass or reciprocating scan mode. It then sends a height increment command to the main controller of the traveling mechanism 120, which in turn raises the entire cleaning mechanism 130 by a fixed cleaning width, slightly smaller than the effective vertical coverage height of the nozzle water jets, such as 300mm. At this new height, the lateral scan cleaning process is executed again. This cycle repeats, gradually covering the entire cooler 200 from bottom to top, achieving complete cleaning of the entire area of ​​the cooler 200.

[0147] like Figure 9As shown, in some embodiments, the moving mechanism 140 includes a first moving component 141 and a second moving component 142. The first moving component 141 includes a first rotary drive 1411, a first reel 1412, and a first transmission rope 1413. The first rotary drive 1411 is disposed on the first walking component 121. One end of the first transmission rope 1413 is connected to the cleaning mounting base 131. The first transmission rope 1413 is wound around the first reel 1412. The first rotary drive 1411 is connected to the first reel 1412 to drive the first reel 1412 to rotate. The second moving component 142 includes a second rotary drive 1421, a second reel 1422, and a second transmission rope 1423. The second rotary drive 1421 is disposed on the second walking component 122. One end of the second transmission rope 1423 is connected to the cleaning mounting base 131. The second transmission rope 1423 is wound around the second reel 1422. The second rotary drive 1421 is connected to the second reel 1422 to drive the second reel 1422 to rotate.

[0148] The first moving component 141 and the second moving component 142 are respectively placed on both sides of the cleaning mounting base 131 along the first direction, and together pull the cleaning mounting base 131 to move back and forth along the first direction. The first rotary drive component 1411 is fixed at the corresponding position of the first traveling component 121, and serves as the power source for the rotation of the first reel 1412; the first reel 1412 is connected to the output end of the first rotary drive component 1411, and can rotate synchronously with the output end in the forward or reverse direction to realize the winding and unwinding of the first transmission rope 1413; the first transmission rope 1413 is wound in the rope groove of the first reel 1412, and its free end is connected to the side of the cleaning mounting base 131 facing the first traveling component 121, which can convert the circumferential force generated by the rotation of the first reel 1412 into a linear traction force, driving the cleaning mounting base 131 to move along the first direction. The second rotary drive component 1421 is fixed at the corresponding position of the second traveling assembly 122, serving as the power source for the rotation of the second reel 1422. The second reel 1422 is connected to the output end of the second rotary drive component 1421, and works in conjunction with the first reel 1412 to synchronously wind up and unwind the second transmission rope 1423. The free end of the second transmission rope 1423 is connected to the side of the cleaning mounting base 131 facing the second traveling assembly 122, and works in conjunction with the first transmission rope 1413 to balance the force on both sides of the cleaning mounting base 131, thereby improving the stability of the movement process.

[0149] The first rotary drive component 1411 and the second rotary drive component 1421 can be servo motors, stepper motors, pneumatic motors, etc. The first transmission rope 1413 and the second transmission rope 1423 can be steel wire ropes, nylon ropes, aramid fiber ropes, etc. The first reel 1412 and the second reel 1422 can be in the form of I-beam reel structures, V-grooved reel structures, smooth drum structures, etc.

[0150] The mobile mechanism 140 adopts a traction structure with a reel and a transmission rope. This structure is simple, has few components, and is easy to manufacture and assemble, facilitating later maintenance and adjustment. Furthermore, the first rotary drive component 1411 is located on the first traveling assembly 121, and the second rotary drive component 1421 is located on the second traveling assembly 122. The power components are synchronously arranged with the traveling assemblies on both sides. When the telescopic rod 112 adjusts the distance between the first and second traveling assemblies 121 and 122, the relative distance between the reels and the transmission rope on both sides can be adjusted synchronously. The lateral movement of the cleaning mounting base 131 can also be adjusted according to the width, reducing motion interference between structures and adapting to the cleaning needs of coolers 200 with different widths.

[0151] like Figures 1-3 As shown, in some embodiments, the first moving component 141 further includes a first guide pulley 1414, which is located on the transmission path between the cleaning mounting base 131 and the first reel 1412. The first transmission rope 1413 extends from the cleaning mounting base 131 towards the first traveling component 121, first passes through the groove of the first guide pulley 1414 to change its transmission direction, and then winds into the rope groove of the first reel 1412. Through the reversing action of the first guide pulley 1414, the mounting layout of the first rotary drive component 1411 and the first reel 1412 on the first traveling component 121 can be flexibly adapted. Of course, in other embodiments, the first guide pulley 1414 may be omitted to reduce the number of parts and lower costs.

[0152] like Figures 1-3 As shown, in some embodiments, the second moving component 142 further includes a second guide pulley 1424, which is located on the transmission path between the cleaning mounting base 131 and the second reel 1422. The second transmission rope 1423 extends from the cleaning mounting base 131 towards the second traveling component 122, first passing through the groove of the second guide pulley 1424 to change its transmission direction, and then winding into the rope groove of the second reel 1422. Through the reversing action of the second guide pulley 1424, the installation layout of the second rotary drive component 1421 and the second reel 1422 on the second traveling component 122 can be flexibly adapted. Of course, in other embodiments, the second guide pulley 1424 may be omitted to reduce the number of components and lower costs.

[0153] like Figures 11-13As shown, in some embodiments, the first walking assembly 121 includes a walking mounting body 1211 disposed on the mounting base 110, and a first walking wheel 1212, a second walking wheel 1213 and a magnetic element 1214 disposed on the walking mounting body 1211. The magnetic element 1214 is used to magnetically attract the cooler 200. The first walking wheel 1212 and the second walking wheel 1213 are spaced apart, and the magnetic element 1214 is disposed between the first walking wheel 1212 and the second walking wheel 1213.

[0154] The walking mount 1211 is the supporting base of the first walking component 121. The walking mount 1211 is fixed to one end of the telescopic rod 112, and provides mounting points for the first walking wheel 1212, the second walking wheel 1213, and the magnetic component 1214. The walking mount 1211 can be in the form of a plate welding structure, a profile splicing structure, or a casting structure.

[0155] The first traveling wheel 1212 and the second traveling wheel 1213 are arranged at intervals along the traveling direction of the first traveling assembly 121, and are both rotatably mounted on the traveling mounting body 1211. During operation, the wheel surfaces of the first traveling wheel 1212 and the second traveling wheel 1213 simultaneously roll against the back surface 211 of the cooler 200, thereby enabling the cooler cleaning device 100 to travel. The structure of the first traveling wheel 1212 and the second traveling wheel 1213 arranged at intervals can improve the posture stability during travel, distribute the contact load, and reduce the tilting and swaying of the cooler cleaning device 100 during travel.

[0156] The first walking wheel 1212 and the second walking wheel 1213 are connected to a walking drive component 1215. The walking drive component 1215 drives the corresponding first walking wheel 1212 and the second walking wheel 1213 to rotate, thereby realizing the walking of the first walking component 121. The walking drive component 1215 can be a servo motor, a stepper motor, a DC motor, etc.

[0157] A magnetic component 1214 is mounted on the traveling mount 1211 between the first traveling wheel 1212 and the second traveling wheel 1213. During operation, it generates a magnetic attraction force on the metal wall of the cooler 200, ensuring that the first traveling wheel 1212 and the second traveling wheel 1213 remain in contact with the wall, thus limiting the vertical movement and detachment of the cooler cleaning device 100. The magnetic component 1214 can be a permanent magnet, an electromagnet, or other types, and can be selected according to the required attraction force and control requirements.

[0158] The first traveling wheel 1212, the magnetic component 1214, and the second traveling wheel 1213 can also be arranged sequentially along the second direction. This would save the space occupied by the first traveling assembly 121 along the first direction and would also better suit the thinner sidewall of the cooler 200. Of course, the first traveling wheel 1212, the magnetic component 1214, and the second traveling wheel 1213 can also be arranged sequentially along the first direction.

[0159] The mobile mounting body 1211 can be in the form of plate structure, frame structure, box structure, etc.

[0160] The first traveling wheel 1212 and the second traveling wheel 1213 can be made of rubber, polyurethane, nylon, or other types.

[0161] In some examples, the first traveling wheel 1212 and the second traveling wheel 1213 are made of polyurethane. For example, the parameters of the polyurethane wheel are an overall wheel diameter of 120mm and a tread layer thickness of 10mm. This polyurethane wheel adopts a modular structure, with the wheel frame precision-machined from aluminum alloy, ensuring lightweight and high strength. The coefficient of friction between the polyurethane material and the wall surface can reach approximately 0.4. This high coefficient of friction provides sufficient traction for the drive, effectively preventing slippage and improving the reliability of travel. This material also possesses excellent comprehensive properties such as cushioning, shock absorption, and oil resistance, protecting the cooler 200 during operation.

[0162] The magnetic component 1214 can be made of neodymium iron boron permanent magnets, ferrite permanent magnets, electromagnets, etc.

[0163] The first traveling wheel 1212 and the second traveling wheel 1213 can be mounted on the traveling mounting body 1211 by means of wheel axle rotation connection, bearing seat fixing, bolt connection, etc.

[0164] By setting a magnetic component 1214 on the first walking component 121, the magnetic attraction between the magnetic component 1214 and the magnetic side of the cooler 200 allows the first walking component 121 to be stably attached to the side of the cooler 200 without the need for a pre-installed track. This enables it to adapt to the magnetic wall surface, and the adsorption is stable and the movement is precise, which is beneficial for the stable movement of the cooler cleaning device 100 on the vertical wall surface.

[0165] like Figures 11-13 As shown, in some embodiments, the first walking assembly 121 further includes an adjustment member 1216 disposed on the walking mount 1211, the adjustment member 1216 being connected to the magnetic member 1214 to adjust the distance between the magnetic member 1214 and the cooler 200.

[0166] Adjusting component 1216 is a functional component used to adjust the relative distance between magnetic component 1214 and the wall of cooler 200. Adjusting component 1216 can drive magnetic component 1214 to move back and forth in a direction perpendicular to the wall of cooler 200, thereby changing the gap size between the adsorption end face of magnetic component 1214 and the wall of cooler 200, and realizing the adjustment of the adsorption gap.

[0167] The adjusting component 1216 can take the form of a threaded screw 12162 adjusting structure, an eccentric cam adjusting structure, a miniature linear push rod adjusting structure, etc., and can be selected according to the adjustment accuracy, ease of operation and installation space requirements.

[0168] By controlling the magnetic component 1214 to maintain an adjustable working gap with the magnetic back plate of the cooler 200, instead of direct contact, a closed magnetic circuit can be formed to generate a strong adsorption force. This not only improves the adsorption stability between the first walking component 121 and the wall surface, but also avoids frictional wear caused by direct contact between the magnetic component 1214 and the wall surface, thus extending the service life of the component. Furthermore, by utilizing the non-linear decay characteristic of magnetic force with the gap, the adsorption force gradually increases when the gap is reduced and rapidly decreases when the gap is expanded. This allows for a controllable cycle of increasing-maintaining-decreasing adsorption force, and also enables convenient placement and removal of the cooler cleaning device 100. This facilitates on-site installation, placement, disassembly, and relocation of the cooler cleaning device 100. At the same time, the gap size can be flexibly adjusted according to different operating loads and wall conditions to adapt to various operating scenarios.

[0169] In some embodiments, the magnetic component 1214 employs neodymium iron boron (NdFeB) permanent magnet material. This material possesses extremely high maximum energy product and coercivity, enabling it to output a powerful magnetic field force within a small volume. For example, the single-sided walking assembly can provide a rated attraction force of approximately 1000N with a nominal working gap of 5mm. Even with a working gap of 10mm, it can still maintain an attraction force of approximately 700N. The magnetic force-distance curve exhibits typical nonlinear decay characteristics; the magnetic force decay rate increases sharply when the gap exceeds 10mm.

[0170] The magnetic component 1214 is provided with a through hole 12141 as a function for installation and positioning. In order to prevent the neodymium iron boron material from being brittlely damaged by impact and to reduce the possibility of irreversible demagnetization (demagnetization) under strong impact or vibration, the magnetic component 1214 is encapsulated with epoxy resin 12142. This not only effectively resists the collisions that may occur during operation and running, but also provides a robust physical protection. It also protects the magnet and inhibits irreversible changes in its internal magnetic domain structure under reverse magnetic field or severe mechanical stress, thus maintaining its magnetic properties stably for a long time.

[0171] like Figures 11-13As shown, in some embodiments, the adjusting member 1216 includes a fixed base 12161 and a screw 12162, a magnetic member 1214 is disposed on the fixed base 12161, the screw 12162 is threadedly connected to the walking mount 1211, and one end of the screw 12162 is connected to the fixed base 12161.

[0172] The mounting base 12161 is a mounting carrier for supporting the magnetic component 1214. It is fixedly connected to the magnetic component 1214 and provides a stable mounting reference for the magnetic component 1214. The mounting base 12161 can be designed into plate type, seat type or other structural forms according to the external dimensions of the magnetic component 1214 to improve the posture stability and force uniformity of the magnetic component 1214 after installation.

[0173] The screw 12162 is a transmission component for adjusting the gap. It is arranged along the wall of the cooler 200 and the screw body is machined with external threads to form a threaded fit with the threaded hole of the traveling mount 1211.

[0174] In some examples, the threaded hole can be directly formed on the walking mount 1211, or it can be formed by installing a nut 12111 on the walking mount 1211, with the inner hole of the nut 12111 forming the threaded hole, or other methods.

[0175] The end of the screw 12162 is connected to the fixed base 12161. When the screw 12162 is rotated, the screw 12162 can move back and forth along its own axis through the transmission action of the threaded pair, thereby driving the fixed base 12161 and the magnetic component 1214 to move synchronously along the direction of the vertical cooler 200 wall, so as to realize the adjustment of the distance between the magnetic component 1214 and the cooler 200.

[0176] The adjusting component 1216 adopts a threaded transmission structure with screw 12162 and fixed base 12161. The structure is simple, with few components, low processing and manufacturing cost, and convenient assembly. The threaded transmission has the characteristics of continuously adjustable stroke and controllable adjustment accuracy. Operators can precisely adjust the gap size of magnetic component 1214 by turning screw 12162. The operation method is simple and intuitive, which makes it easy for on-site operators to quickly complete the adjustment of adsorption force and the assembly and disassembly of the device.

[0177] like Figures 14-17 As shown, in some embodiments, the first walking assembly 121 further includes a guide wheel 1217 disposed on the walking mount 1211, the axis of the guide wheel 1217 being perpendicular to the axis of the first walking wheel 1212, such that the guide wheel 1217 abuts against the inner side surface 212 of the cooler 200.

[0178] The guide wheel 1217 is a component in the first traveling assembly 121 used for lateral travel limiting and guidance. The guide wheel 1217 is rotatably mounted on the corresponding position of the traveling mount 1211, and its own axis of rotation is spatially perpendicular to the axis of rotation of the first traveling wheel 1212. The axis of the first traveling wheel 1212 is parallel to the back surface 211 of the cooler 200. During operation, the wheel surface of the first traveling wheel 1212 rolls against the back surface 211 of the cooler 200, and the cooler cleaning device 100 travels in a vertical direction.

[0179] Of the two opposing sides of the sidewall of the housing 210 of the cooler 200 that allow the first traveling wheel 1212 to travel along its own thickness direction, the side facing the inside of the housing 210 is called the inner side 212 of the cooler 200, and the side facing away from the inside of the housing 210 is called the outer side 213 of the cooler 200; the axial direction of the guide wheel 1217 is parallel to the inner side 212 of the cooler 200 and is arranged in a horizontal direction, and the wheel surface of the guide wheel 1217 abuts against the inner side 212 of the cooler 200 during operation.

[0180] The guide wheel 1217 can be mounted on the traveling mount 1211 by means of axle rotation connection, bearing seat fixation, bolt connection, etc. The guide wheel 1217 can be made of rubber wheel, polyurethane wheel, nylon wheel, metal wheel, etc.

[0181] For example, the guide wheel 1217 is a polyurethane wheel with a certain degree of elasticity, which can be engaged with the inner side 212 of the cooler 200 to reduce rigid impact and noise, while providing reliable lateral restraint.

[0182] By having the guide wheel 1217 abut against the inner surface 212 of the cooler 200, a constraint point can be formed in the lateral direction of the first walking component 121, passively restricting the lateral degree of freedom of the first walking component 121. When the device tends to deviate laterally due to installation errors or wall flatness deviations, the structure of the inner surface 212 of the cooler 200 will generate a lateral constraint reaction force on the guide wheel 1217, forcing the device to return to the preset walking track. This helps to ensure the straight-line accuracy in long-stroke motion, effectively suppress deviation, and improve the vertical walking position accuracy and running stability of the device.

[0183] In some embodiments, the number of guide wheels 1217 can be set to one, two, or more as needed. Multiple guide wheels can achieve multi-point constraints, which is beneficial for improving the straightness of long-stroke travel. For example, the number of guide wheels 1217 is seven.

[0184] In some embodiments, the guide wheel 1217 can be engaged in a groove on the inner side 212 of the cooler 200, thereby enabling the first traveling assembly 121 to travel in a direction perpendicular to the back surface 211 of the cooler 200 (see reference). Figure 1The X-direction of the device acts as a limit, reducing the risk of the cooler cleaning device 100 falling off the back 211 of the cooler 200.

[0185] In some embodiments, the walking mount 1211 is provided with a guide rod 12112, and the fixed base 12161 is provided with a sliding hole 12164. The guide rod 12112 passes through the sliding hole 12164 to guide the fixed base 12161 to move, making the adjustment operation of the magnetic component 1214 more reliable. The fixed base 12161 is provided with a sliding sleeve 12163, and the inner hole of the sliding sleeve 12163 forms the sliding hole 12164. Its structure is simple, its processing and manufacturing are simple, and its sliding guidance is smooth, which is beneficial to the adjustment of the magnetic component 1214.

[0186] like Figures 14-16 , Figure 18 As shown, in some embodiments, the first walking assembly 121 further includes an abutment drive member 1218 and an abutment member 1219. The abutment drive member 1218 is disposed on the walking mount 1211, and the output end of the abutment drive member 1218 is connected to the abutment member 1219 to drive the abutment member 1219 to abut against the outer surface 213 of the cooler 200.

[0187] The abutment drive 1218 is a power component that provides the abutment preload to the abutment member 1219. The output end of the abutment drive 1218 can reciprocate in a direction perpendicular to the outer surface 213 of the cooler 200, driving the abutment member 1219 to move closer to or away from the outer surface 213 of the cooler 200, thereby realizing the start and stop of the abutment state and the adjustment of the abutment force. The abutment drive 1218 can be of the type of miniature linear push rod, elastic clamping assembly, small pneumatic cylinder, snake head cylinder, etc., and can be selected according to the required abutment force, installation space, and control requirements.

[0188] By having the abutment 1219 abut against the outer surface 213 of the cooler 200, a lateral constraint point is formed, passively restricting the lateral degree of freedom of the first walking component 121. When the cooler cleaning device 100 has a lateral offset tendency due to wall flatness deviation or installation error during long-stroke walking, the outer surface 213 of the cooler 200 will generate a lateral constraint reaction force on the abutment 1219, forcing the cooler cleaning device 100 to return to the preset walking path, improving the straight-line accuracy in long-stroke movement, effectively suppressing deviation, and improving the vertical walking position accuracy and running stability of the device.

[0189] In some embodiments, the abutment 1219 abuts against the outer side 213 of the cooler 200, and the guide wheel 1217 abuts against the inner side 212 of the cooler 200. The abutment 1219 and the guide wheel 1217 can also clamp the side wall of the cooler 200, effectively suppressing deviation.

[0190] In some embodiments, the first walking component 121 and the second walking component 122 have the same structure.

[0191] The second walking assembly 122 also includes components such as a walking mount 1211, a first walking wheel 1212, a second walking wheel 1213, and a magnetic component 1214. The structure, connection method, and function of each component are the same as the corresponding components in the first walking assembly 121.

[0192] By setting the first walking component 121 and the second walking component 122 to the same structure, it is convenient to manufacture and assemble, which helps to reduce manufacturing costs. Furthermore, the parts of the two are interchangeable, which facilitates later maintenance and replacement.

[0193] In some embodiments, when the first walking assembly 121 is in use, the cooler cleaning device 100 is moved to the back side 211 of the cooler 200, so that the side of the walking mechanism 120 with the magnetic element 1214 is approximately parallel to and close to the metal wall of the cooler 200, and the initial distance between them is controlled, for example, the initial distance is less than 100mm.

[0194] Tighten the screw 12162 again to drive the fixed base 12161 and the magnetic component 1214 to move relative to the walking mount 1211 in a direction perpendicular to the wall, and precisely adjust the gap between the magnetic component 1214 and the wall of the cooler 200 to achieve continuous control of the magnetic force. For example, the adjustable working gap range of the magnetic component 1214 is 5mm to 40mm.

[0195] The rotating screw 12162 pushes the magnetic component 1214 to move smoothly towards the wall of the cooler 200. At the same time, the scale component on the cooler cleaning device 100 monitors the gap value in real time and precisely adjusts the working gap to the first preset value d1. At the first preset value d1, the magnetic components 1214 of the first walking component 121 and the second walking component 122 jointly generate a total magnetic attraction force, causing the entire cooler cleaning device 100 to be adsorbed onto the vertical wall of the cooler 200.

[0196] For example, the first preset value d1 can be set to 5mm ± 1mm, and the total adsorption magnetic force generated by the magnetic components 1214 of the walking components on both sides can reach 2000N. The adsorption safety verification step is used to verify the safety and reliability of the adsorption state.

[0197] The total weight of the cooler cleaning device 100 is G, the static friction coefficient between the first traveling wheel 1212 and the wall is μ, and the maximum static friction force F that the cooler cleaning device 100 can provide is... fmax =μ F 总 .

[0198] Define the safety factor K = F fmax / G, when the safety factor is greater than the preset safety threshold, the device is determined to be firmly adsorbed and the device is suspended on the vertical wall surface by static friction.

[0199] For example, the total weight G of the device can be 373N, the measured static friction coefficient μ between the traveling wheel and the carbon steel sidewall is about 0.4, the corresponding maximum static friction force is about 800N, the safety factor is about 2.14, which is greater than the preset safety threshold of 1.5, and the adsorption state is stable.

[0200] The industrial control computer sends a drive pulse command to the walking drive component 1215 to control the walking drive component 1215 to rotate at a preset speed ω, which corresponds to the wall climbing walking speed v of the cooler cleaning device 100. For example, the walking speed can be adjusted in the range of 0.1m / s to 0.5m / s.

[0201] The rated torque of the walking drive component 1215 is amplified by the reduction assembly and then output to the first walking wheel 1212 and the second walking wheel 1213.

[0202] For example, the rated torque of the walking drive component 1215 can be 16 N. m. The torque-friction conversion stage is used to convert rotational torque into driving force.

[0203] Under the normal pressure generated by magnetic adsorption, the first traveling wheel 1212 and the second traveling wheel 1213 are tightly fitted against the wall of the cooler 200; the torque output by the traveling drive component 1215 is converted into a tangential driving force on the rims of the first traveling wheel 1212 and the second traveling wheel 1213, which is less than the maximum static friction force F. fmax The first traveling wheel 1212 and the second traveling wheel 1213 do not slip with the wall surface, and the cooler cleaning device 100 moves vertically upward or downward along the wall surface through static friction.

[0204] During the movement of the cooler cleaning device 100, the guide wheels 1217 on both sides of the traveling mechanism 120 simultaneously engage for guidance. The guide wheels 1217 are pre-loaded with a preset clamping force during installation, ensuring that the wheel surfaces of the guide wheels 1217 are always in contact with the inner surface 212 of the cooler 200. When the cooler cleaning device 100 exhibits a lateral shift due to installation errors or wall flatness deviations, the inner surface 212 of the cooler 200 provides a lateral restraint reaction force to the guide wheels 1217, forcing the cooler cleaning device 100 back to its central traveling track.

[0205] The precise stopping and non-powered hovering of the cooler cleaning device 100 at the target cleaning station includes two stages: arrival at the target station and braking, and static force holding.

[0206] The target station arrival and braking mechanism is used to control the cooler cleaning device 100 to precisely stop at the target height. When the position detection component on the cooler cleaning device 100 reports that the cooler cleaning device 100 has reached the preset cleaning height Hn, the control system stops sending drive pulses to the travel drive component 1215 and triggers the electromagnetic braking component built into the travel drive component 1215, causing the cooler cleaning device 100 to stop moving immediately. The position detection component can take the form of an encoder located on the top of the cooler cleaning device 100, a vision sensor located on the bottom of the cooler cleaning device 100, or the like.

[0207] The static force holding element is used to maintain the suspended state of the cooler cleaning device 100. After the cooler cleaning device 100 stops, the total magnetic adsorption force continues to act, and the static friction between the first traveling wheel 1212 and the second traveling wheel 1213 and the wall surface is balanced by the gravity of the cooler cleaning device 100, with the static friction force pointing vertically upward. The cooler cleaning device 100 is stably suspended at the target position without any power input, providing a static working reference platform for subsequent horizontal cleaning operations.

[0208] The cooler cleaning device 100 can be safely and controllably disassembled from the side wall of the cooler 200, which includes three steps: magnetic attenuation preparation, gap adjustment to the critical value, and controllable disassembly.

[0209] The magnetic attenuation preparation stage serves as a preparatory step for device disassembly. After all cleaning operations are completed, the cooler cleaning device 100 is returned to its initial low position; the operator operates the adjusting component 1216 to rotate the screw 12162 in the opposite direction, causing the fixed base 12161 and the magnetic component 1214 to move away from the wall of the cooler 200.

[0210] The gap adjustment to the critical value step is used to weaken the magnetic attraction force to a critical state. The working gap of the magnetic component 1214 of the single-sided walking component is adjusted from the first preset value d1 to the second preset value d2; according to the magnetic force-distance characteristics of the magnetic component 1214, the total magnetic attraction force decreases sharply at the second preset value d2.

[0211] For example, the second preset value d2 can be set to 10mm~15mm, corresponding to the magnetic force of adsorption on one side decreasing to the range of 400N~700N.

[0212] The controllable release mechanism is used to safely disassemble the device. At this point, the maximum static friction of the cooler cleaning device 100 is reduced to a level equal to or slightly lower than its own weight. Operators can then apply a small lateral prying force or vertical lifting force to overcome the remaining adhesion and friction, safely removing the cooler cleaning device 100 from the wall of the cooler 200. This method utilizes the non-linear decay of magnetic force with gap to achieve controllable and rapid release of the cooler cleaning device 100, improving the ease of disassembly and operational safety.

[0213] like Figure 1 and Figure 2 As shown, in some embodiments, the cooler cleaning device 100 further includes a fall arrestor 150 connected to the walking mechanism 120.

[0214] The fall arrestor 150 is a component used to provide safety protection and prevent the cooler cleaning device 100 from falling in the event of an accidental detachment.

[0215] Both the first walking assembly 121 and the second walking assembly 122 are equipped with fall arresters 150. One end of the fall arrester 150 can be connected to the walking mount 1211 by means of bolt connection, hook connection, wire rope binding, etc. The other end of the fall arrester 150 can be fixed to the top of the cooler 200 by means of hooking, clamping, etc.

[0216] The fall arrestor 150 can be selected from types such as speed difference self-controlled fall arrestor, rail-mounted fall arrestor, and rope-grabbing fall arrestor.

[0217] When the cooler cleaning device 100 falls accidentally, the locking mechanism inside the fall arrestor 150 locks quickly under the action of centrifugal force, thereby preventing the cooler cleaning device 100 from continuing to fall. It has a fast response speed and high safety and reliability.

[0218] By setting a fall arrestor 150 connected to the walking mechanism 120, safety protection can be provided when the cooler cleaning device 100 is accidentally detached, reducing the possibility of the cooler cleaning device 100 falling from a height, which is conducive to improving the safety of the cooler cleaning device 100 in high-altitude operation scenarios.

[0219] In some embodiments, the operation method of the cooler cleaning device 100 includes a rapid on-site deployment and adaptive configuration step, an intelligent cleaning main circulation step, and a job completion and rapid recovery step.

[0220] Rapid on-site deployment and adaptive configuration steps. This step is used to complete the on-site layout and working condition adaptation of the cooler cleaning device 100, including five steps: ground power and control system station layout, pipeline connection, adsorption and positioning of the walking mechanism 120, width adaptation of the first walking component 121 and the second walking component 122, and parameter initialization.

[0221] The deployment phase of the ground power and control system station is used to build the operational power foundation, move the integrated ground power and control system station to the operational site, and fix it in place.

[0222] The pipeline connection is used to establish a passage between the ground power and control system station and the main working body. The water and electrical circuits between the main working body, which is integrated with the walking mechanism 120, the mounting base 110, the moving mechanism 140 and the cleaning mechanism 130, are completed through the water and electrical quick-connect coupling.

[0223] The walking mechanism 120 is used to adsorb and position the cooler cleaning device 100 on the wall of the cooler 200. The operator places the main body equipped with the cleaning mechanism 130 close to the back 211 of the cooler 200 and operates the adjustment component 1216 to adjust the gap between the magnetic component 1214 and the wall of the cooler 200, so that the magnetic component 1214 is adsorbed on the wall of the cooler 200 with a preset working gap.

[0224] The widths of the first walking assembly 121 and the second walking assembly 122 are adapted to match the width of the cooler 200. Based on the actual width of the cooler 200 to be cleaned, the telescopic rod 112 is manually adjusted to the matching length and locked in place by the locking element.

[0225] The parameter initialization step is used to complete the initial configuration of the operation parameters. The structural dimension parameters of the cooler 200 are input through the human-machine interaction module of the electrical control cabinet, and the cooler cleaning device 100 is controlled to complete the initial setting of the operation parameters of each mechanism.

[0226] The main cycle of intelligent cleaning is the core operation of two-dimensional planar collaborative cleaning. The electrical control cabinet coordinates the various mechanisms to perform vertical positioning and pipeline synchronization, horizontal scanning and composite cleaning, full-process visual monitoring, and layered advancement of the full-coverage operation process according to the preset path.

[0227] Vertical positioning and pipeline synchronization: The electrical control cabinet controls the walking mechanism 120 to drive the cleaning mechanism 130 to move vertically to the preset target height; at the same time, the automatic pipe release and retraction device releases or retracts the corresponding length of water and electricity composite pipeline according to the real-time displacement information of the walking mechanism 120, so that the tension of the water and electricity composite pipeline is within the preset reasonable range, avoiding dragging or tangling of the water and electricity composite pipeline.

[0228] Lateral scanning and composite cleaning process: At the current target height, the electrical control cabinet controls the moving mechanism 140 to drive the cleaning mounting base 131 and the cleaning mechanism 130 to move laterally back and forth along the telescopic rod 112; during the movement, the rotating drive component 132 is synchronously controlled to drive the rotating mounting base 133 and the cleaning head 134 to swing periodically back and forth.

[0229] The combined motion of lateral movement and the oscillation of the cleaning head 134 causes the high-pressure water jet ejected from the cleaning head 134 to form a mesh-like path covering the surface of the heat dissipation fins 220, achieving two-dimensional surface cleaning.

[0230] Full-process visual monitoring: The camera 136 integrated on the cleaning mechanism 130 continuously collects images during operation and transmits the images of the cleaning area to the electrical control cabinet for display in real time, allowing operators to monitor the cleaning status throughout the process; the air nozzle 137 of the camera 136 operates at regular intervals to remove water mist from the surface of the camera 136 and improve image clarity.

[0231] Layered approach to full coverage: After completing the cleaning operation at the current height level, the electrical control cabinet controls the walking mechanism 120 to drive the cleaning mechanism 130 to the next height level, repeating the horizontal scanning and composite cleaning, and the whole process of visual monitoring, advancing layer by layer until the cleaning operation of the entire back 211 of the cooler 200 is completed.

[0232] Operation Completion and Rapid Recovery Steps: This step is used for equipment recovery and data aggregation after the operation is completed, and includes four stages: equipment reset, equipment disassembly, pipeline recovery, and report generation.

[0233] Device reset procedure: After all cleaning operations are completed, the electrical control cabinet controls the walking mechanism 120 to drive the cleaning mechanism 130 back to the initial low position.

[0234] Device disassembly process: After adjusting the device 1216 to increase the working gap between the magnetic component 1214 and the side wall of the cooler 200, and significantly weakening the magnetic attraction force, the main body of the device is removed from the side wall of the cooler 200.

[0235] Pipeline recovery process: Activate the automatic pipe recovery device to neatly recover the water and electricity composite pipelines onto the reel of the automatic pipe recovery device.

[0236] Report generation stage: The electrical control cabinet summarizes the operating parameters, cleaning duration, and work area of ​​this operation, generates and stores the operation report of this cleaning operation.

[0237] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
