DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.

[0028] like Figures 1 to 6 As shown, an automated production line for cleaning and coating the inner cavity of a transformer radiator includes a degreasing and cleaning device 01, a moisture drying device 02, an inner wall paint filling device 03, an inner wall paint control device 04, a drying and curing device 05 and a ring-shaped accumulation conveyor chain 06. The degreasing and cleaning device 01 includes a degreasing and cleaning tank and a water washing tank. The moisture drying device 02 includes a drying room body, a heating device, a circulating fan and a heating air duct. An exhaust port is provided on the top of the drying room body. The heating air duct connects the drying room body, the heating device and the circulating fan to form a circulation loop. The inner wall painting device includes a paint pool, a paint pumping device 031, a paint filling fixture and a paint filling online detection device 034. The paint pumping device 031 is connected to the paint pool.

[0029] The drying and curing device 05 includes a drying room, a heating device, a circulating air blower and a connecting pipe. The connecting pipe connects the drying room, the heating device and the circulating air blower to form a circulation loop.

[0030] The annular accumulation conveyor chain 06 includes a drive assembly, a supporting structure and an accumulation trolley. The drive assembly and the accumulation trolley are arranged on the supporting structure, and the drive assembly is used to drive the accumulation trolley to move.

[0031] The present embodiment is an automated production line for cleaning and coating the inner cavity of a transformer radiator. During operation, the radiator is automatically transported by a circular accumulation conveyor chain 06 and controlled by an inner wall paint control device 04. At the same time, it passes through a degreasing cleaning device 01, a moisture drying device 02, an inner wall paint coating device 03 and a drying and curing device 05 in sequence by relying on the circular accumulation chain. Degreasing and cleaning are performed in the degreasing cleaning device 01, and then the paint is dried in the moisture drying device to facilitate coating. The paint is then sent to the inner wall coating device for coating, thereby achieving efficient and automatic coating. During the coating process, the paint coating online detection device 034 performs real-time online detection to determine whether the coating work is completed.

[0032] The paint filling fixture includes a connecting plate 032, a pneumatic fixture 033 and a paint supply pipe 035. The pneumatic fixture 033 is fixed to the connecting plate 032, and the paint supply pipe 035 is connected to the connecting plate 032. When in use, the pneumatic fixture 033 is connected to the flange on the radiator to form a paint filling circuit.

[0033] This embodiment is an automated production line for cleaning and coating the inner cavity of a transformer radiator. A waste liquid collection device is provided at the bottom of the degreasing and cleaning device 01. The waste liquid collection device includes a floor mat 4, a filter plate 6, a flushing component 7 and a collection component 8. A drain port 5 is provided on the floor mat 4. The filter plate 6 is provided on the drain port 5. The flushing component 7 is provided at the filter plate 6 for flushing the filter plate 6. The collection component 8 includes a bracket and a liquid guide groove 9. The liquid guide groove 9 is tilted on the bracket, and the lower end of the liquid guide groove 9 is aligned with the filter plate 6.

[0034] In the process of degreasing and cleaning, an automated production line for cleaning and coating the inner cavity of a transformer radiator of this embodiment generates wastewater, which is collected by the waste liquid collecting device. During the collection, the floor mat 4 guides the waste liquid so that the waste liquid enters the drain port 5 and is filtered by the filter plate 6. The filter plate 6 here is only used to filter larger objects. At the same time, the flushing component 7 impacts the material attached to the filter plate 6 to prevent the material from adhering to and solidifying on the filter plate 6 for a long time, which affects the filtering effect of the filter plate 6.

[0035] Specifically, the bracket includes a bottom frame 10, a first side frame 11 and a second side frame 12. The first side frame 11 and the second side frame 12 are relatively arranged on the bottom frame 10. The bottom frame 10 is arranged on the floor mat 4. The two side edges of the liquid guide groove 9 are respectively connected to the first side frame 11 and the second side frame 12.

[0036] The flushing assembly 7 includes an annular guide rail 13, a water pipe 16 and a movable flushing member 17. The annular guide rail 13 surrounds the filter plate 6. The movable flushing member 17 includes a first caster 18, a second caster 19, a movable wheel 20, a driving component, a main body 21 and a flushing nozzle 25. The first caster 18 and the second caster 19 are arranged at the bottom of the main body 21 and cooperate with the annular guide rail 13. The movable wheel 20 is arranged in the main body 21 and protrudes from the bottom of the main body 21 and contacts the upper surface of the annular guide rail 13. The driving component is arranged in the main body 21 for driving the movable wheel 20 to rotate. The flushing nozzle 25 is arranged on the main body 21 and is connected to the water pipe 16. Under the above structural design, the water supply pipe 16 supplies water to the flushing nozzle 25, so that the flushing nozzle 25 sprays water, and the sprayed water impacts the surface of the filter plate 6, flushing away the materials attached to the surface of the filter plate 6. At the same time, through the drive of the driving component, the moving wheel 20 rotates, thereby driving the moving flushing part 17 to move along the annular guide rail 13, and the filter plate 6 is fully flushed during the movement.

[0037] To ensure that the mobile flushing unit 17 can be stably engaged with the annular guide rail 13, a first extension edge 14 and a second extension edge 15 are respectively provided on the top and side edges of the annular guide rail 13. A first caster 18 and a second caster 19 are arranged opposite each other, with the first caster 18 hooking onto the lower surface of the first extension edge 14, and the second caster 19 hooking onto the lower surface of the second extension edge 15. With this structural arrangement, the first caster 18 and the second caster 19 embrace the first extension edge 14 and the second extension edge 15, and the mobile wheel 20 abuts against the upper surface of the annular guide rail 13, ensuring that the mobile flushing unit 17 is stably engaged with the annular guide rail 13.

[0038] In order to further improve the stabilization effect, at least two of the first casters 18 and the second casters 19 are provided.

[0039] Furthermore, the drive assembly includes an impeller 26 and a connecting belt. The connecting belt connects the axle of the impeller 26 to the axle of the movable wheel 20. The body 21 defines an inner cavity 22, within which the impeller 26 is located. The connection path between the water pipe 16 and the flushing nozzle 25 passes through the inner cavity 22. During operation, water flows through the inner cavity 22, impacting the impeller 26 and causing it to rotate. This rotation, driven by the connecting belt, drives the movable wheel 20, thereby enabling the movable flushing element 17 to move autonomously under the impact of the water flow. This effectively simplifies the structure, saves energy, and improves operational convenience.

[0040] Furthermore, the driving component also includes a shift rod 27, an adjustment block 28 and an adjustment rod 29, the adjustment block 28 is connected to the adjustment rod 29, an adjustment chamber 24 is provided at the top of the inner cavity 22, and a water outlet 23 is provided at the bottom of the inner cavity 22, the water outlet 23 is communicated with the flushing nozzle 25, the adjustment chamber 24 is communicated with the water pipe 16, the adjustment block 28 is provided in the adjustment chamber 24, one end of the adjustment rod 29 is connected to the adjustment block 28, and the other end passes through the body 21, the shift rod 27 is provided on the floor mat 4, and is used to shift the adjustment rod 29 so that the adjustment rod 29 swings, and the swing of the adjustment rod 29 drives the adjustment block 28 to swing left and right in the adjustment chamber 24. During operation, after the water flows into the regulating chamber 24, it enters the inner chamber 22 from one side of the regulating block 28, impacting the impeller 26 in the inner chamber 22, causing the impeller 26 to rotate, thereby driving the movable flushing member 17 to move in one direction. When the movable flushing member 17 gradually moves so that the lever 27 contacts the regulating rod 29, the regulating rod 29 is toggled. When the regulating rod 29 is toggled, the regulating block 28 is driven to be toggled to the other side of the regulating chamber 24, so that the water flows from the other side of the regulating block 28 into the inner chamber 22, causing the impeller 26 to rotate in the opposite direction, thereby causing the movable flushing member 17 to change its moving direction and move in the opposite direction. Therefore, under such a structural setting, the movable flushing member 17 will reciprocate on the annular guide rail 13, continuously and comprehensively impacting and cleaning the filter plate 6. At the same time, since the movement is reciprocating, it also avoids the water supply pipe 16 from getting tangled and entangled during the movement of the movable flushing member 17, causing it to be damaged.

[0041] Specifically, the rod portion of the adjusting rod 29 is connected to the cavity wall of the adjusting cavity 24 by a pin shaft to realize the rotation setting of the adjusting rod 29. A sealing structure should be provided at the connection between the adjusting rod 29 and the adjusting cavity 24, such as a sealing block. This is a method that can be easily implemented by those skilled in the art.

[0042] It should be noted that, in this document, relational terms such as first and second, etc., are used solely to distinguish one entity or operation from another, and do not necessarily require or imply any actual relationship or order between these entities or operations. Furthermore, the terms "include," "comprise," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or terminal device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or terminal device.
