Description

Technical Field

[0001] The invention relates to the technical field of spray devices, in particular to a surface coating device for transformer plate radiators. Background Art

[0002] The plate heat sink of the transformer mainly consists of two metal tubes and multiple metal heat sinks. The heat sink is hollow inside, and the two ends of the multiple heat sinks are respectively connected to the circumference of the two metal tubes, and the two metal tubes are connected to the outer shell of the transformer. There is cooling oil in the transformer shell, and the cooling oil is used to cool the coils, cores and other components in the transformer shell; the cooling oil flows into the heat sink through the metal tubes, and the heat sink uses its larger surface to contact with the air to dissipate heat and reduce the temperature of the cooling oil.

[0003] In order to extend the service life of the fin radiator, it is necessary to apply anti-corrosion paint on the outer surface of the fin radiator to improve the corrosion resistance of the fin radiator, especially the corrosion caused by rainwater.

[0004] In the related art, when spraying paint on a fin-type radiator, two metal tubes are fixed separately by two clamps, and then the two clamps are lifted by a gantry, and then the paint is sprayed to the fin-type radiator through the nozzle at the end of the feed pipe; however, when spraying the paint, since the clamp partially blocks the metal tube, the paint cannot be sprayed on the blocked part, and the blocked part needs to be sprayed after drying.

The end of the pushing cylinder 942 is installed between the two fixed plates 941, and the end of the piston rod of the pushing cylinder 942 is connected to the end of the support rod 5.

[0051] When it is necessary to fix the tube body 11, the push cylinder 942 pushes the support rod 5 through the piston rod, and the support rod 5 drives the push block 92, and the push block 92 pushes the clamping block 93 through the slope. Since the second T-block 932 slides in the second T-slot 911, the four clamping blocks 93 are gradually expanded, and the first T-block 931 slides in the first T-slot 921, and the four clamping blocks 93 are gradually pressed against the inner wall of the tube body 11, so that the tube body 11 can be fixed, and combined with the positioning ring 41, the stability of the fin radiator 1 on the support rod 5 can be improved; when it is necessary to release the fixation of the tube body 11, the push cylinder 942 pulls back the piston rod, and the piston rod drives the support rod 5, and the support rod 5 returns to the push block 92, and the push block 92 pulls back the four clamping blocks 93 through the first T-slot 921 and the first T-block 931, so that the four clamping blocks 93 gradually approach each other, and the squeezing of the inner wall of the tube body 11 is released, so that the fixation of the tube body 11 can be released.

[0052] An annular groove 42 is provided on the end face of the rotating seat 4 close to the tube body 11, and a sealing ring 43 is provided in the annular groove 42, and the sealing ring 43 is pressed against the side of the connecting plate 111; when the plate-type radiator 1 is installed on the support rod 5 and the rotating seat 4, the weight of the plate-type radiator 1 is applied to the rotating seat 4, and the connecting plate 111 is pressed against the sealing ring 43, and then the tube body 11 is fixed; during spraying, the sealing ring 43 seals the gap between the connecting plate 111 and the rotating seat 4 to prevent the paint from entering the tube body 11.

[0053] The implementation principle of the surface coating device for a transformer fin radiator 1 according to the embodiment of the present application is as follows: when it is necessary to spray paint on the fin radiator 1, the fin radiator 1 is lifted up by the hanging ring 112, and the driving mechanism 7 drives the rotating shaft to rotate, and the rotating shaft drives the rotating seat 4 to rotate, and the rotating seat 4 rotates to a vertical state, at which time the support rod 5 is vertically facing upward; the lifted fin radiator 1 is moved above the support rod 5, and the two tubes 11 are aligned with the two support rods 5, so that the support rod 5 is inserted into the tube body 11, and the hanging ring 112 and the hook are released, at which time the bottom end of the tube body 11 is attached to the top surface of the rotating seat 4; then the driving mechanism 7 drives the rotating shaft to rotate, and the rotating shaft drives the rotating seat 4 is rotated 90° to make the rotating seat 4 horizontally arranged. At this time, the support rod 5 is also in a horizontal state, and the fin-type radiator 1 on the support rod 5 is also in a horizontal state; then the moving mechanism 8 drives the spray head 6 to move, and the spray head 6 sprays the paint on the fin-type radiator 1. Since the hollow fins 12 of the fin-type radiator 1 are in a vertical state, the paint sprayed on the top of the hollow fins 12 flows downward along the hollow fins 12 to form a protective film; the fin-type radiator 1 is propped up by the tube body 11 in cooperation with the support rod 5, so that there is no shielding part on the fin-type radiator 1, and the paint sprayed by the spray head 6 can be sprayed on the surface of the fin-type radiator 1, thereby improving the spraying efficiency of the fin-type radiator 1.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
