[0002] A transformer casing painting device is a device specifically designed for automated or semi-automated painting of transformer casings.

[0003] In the existing technology, when the transformer shell is being sprayed, paint is sprayed onto the surface of the transformer shell through a nozzle. During the spraying process, some of the spray will flow with the airflow and fall onto the filter screen. The filter screen needs to be cleaned and replaced manually at regular intervals to avoid the filter screen clogging and reducing the airflow rate in the spray box. However, replacing the filter screen is too cumbersome, requiring manual removal of the bolts that fix the filter screen in order to replace and install a new filter screen, which is too time-consuming. Utility Model Content

Four equidistant limiting frames connected to the through holes are fixedly installed inside the spray box. Two pairs of symmetrically arranged clamping rods are fixedly installed within each of the four limiting frames, and a filter plate is slidably arranged within each pair of clamping rods. The spray box has four equidistant placement holes for placing and removing the filter plate between the two pairs of clamping rods.

[0007] Preferably, two parallel mounting plates are fixedly installed in each of the four through holes of the spray box, and a fan for injecting air from the atmosphere into the spray box is fixedly installed on each of the two mounting plates.

[0008] Preferably, a paint can is fixedly installed on the upper end of the spray box, the upper end of the paint can is provided with a feed port, and the outer wall of the paint can is provided with four output pipes that are equidistantly arranged and whose ends are connected to the inside of the paint can.

[0009] Preferably, four sets of equally spaced nozzles are fixedly installed inside the spray box, and four conveying holes are opened inside the spray box, each connected to one of the four sets of nozzles. The four output pipes are connected to the four conveying holes respectively.

[0010] Preferably, the bottom of the spray box is provided with an installation groove, and a drive motor is fixedly installed in the installation groove. The output end of the drive motor extends into the spray box and is fixedly installed with a placement plate for placing the transformer housing.

[0011] Preferably, the spray box has four equidistant sliding holes, and a limit rod is slidably disposed in each sliding hole. The filter plate has a limit hole for placing the limit rod, and a T-shaped slider is fixedly installed at the end of the limit rod.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-6 A transformer housing painting device includes a spray box 1, which has four equidistant through holes. Four equidistant limiting frames 13 connected to the through holes are fixedly installed inside the spray box 1. Two pairs of symmetrically arranged clamping rods 14 are fixedly installed in each of the four limiting frames 13. A filter plate 15 is slidably arranged in each of the two pairs of clamping rods 14. The spray box 1 has four equidistant placement holes 20 for placing and removing the filter plate 15 between the two pairs of clamping rods 14.

[0025] Two parallel mounting plates 3 are fixedly installed in each of the four through holes of the spray box 1, and a fan 4 is fixedly installed on each of the two mounting plates 3 to inject air from the atmosphere into the spray box 1. The operation of the fan 4 accelerates the air circulation rate in the spray box 1, so that the paint sprayed on the surface of the transformer shell dries quickly.

[0026] A paint can 8 is fixedly installed on the upper end of the spray box 1. A feed port 9 is provided on the upper end of the paint can 8. Four output pipes 7 are provided on the outer wall of the paint can 8 at equal intervals and whose ends are connected to the inside of the paint can 8.

[0027] Four sets of nozzles 6 are fixedly installed inside the spray box 1, and four conveying holes 5 are opened inside the spray box 1, which are respectively connected to the four sets of nozzles 6. Four output pipes 7 are respectively connected to the four conveying holes 5.

[0028] The bottom of the spray box 1 is provided with an installation groove 10, and a drive motor 11 is fixedly installed in the installation groove 10. The output end of the drive motor 11 extends into the spray box 1 and a placement plate 12 for placing the transformer housing is fixedly installed. The placement plate 12 drives the transformer housing to rotate, so that the transformer housing is evenly sprayed with paint.

[0029] The spray box 1 has four equidistant sliding holes 21. A limit rod 19 is slidably installed in the sliding holes 21. The filter plate 15 has a limit hole for placing the limit rod 19. A T-shaped slider 17 is fixedly installed at the end of the limit rod 19.

[0030] The spray box 1 has four T-shaped grooves 16 that are connected to four sliding holes 21 respectively. The T-shaped slider 17 is slidably disposed in the T-shaped groove 16, and multiple horizontally distributed springs 18 are fixedly installed in the T-shaped groove 16, and the ends of the multiple springs 18 are fixedly connected to the T-shaped slider 17.

[0031] The outer wall of the spray box 1 is provided with a door 2, and four limit frames 13 are respectively set between the four nozzles 6.

[0032] The functional principle of this utility model can be explained through the following operation methods:

[0033] In use, the transformer housing is placed on the placement plate 12 inside the spray box 1 by opening the box door 2. The paint liquid is injected into the paint tank 8 from the inlet 9. The paint liquid is delivered to the four delivery holes 5 through the four output pipes. The paint liquid is sprayed out through the four sets of nozzles. At the same time, the drive motor 11 is turned on, so that the output end of the drive motor 11 drives the placement plate 12 to rotate, so that the placement plate 12 drives the transformer housing to rotate, so that the transformer housing is evenly sprayed with paint.

[0034] After the painting is completed, the fan 4 is turned on to send air from the atmosphere into the spray box 1, so that the air in the spray box 1 can circulate and the paint that has been evenly sprayed on the transformer shell can dry quickly.

[0035] When the filter plate 15 needs to be replaced, the T-shaped slider 17 is slid in the T-groove 16 towards the spring 18, compressing the spring 18 and pulling the limiting rod 19 out of the sliding hole 21, thus releasing the limiting rod 19 from limiting the filter plate 15 and facilitating the quick replacement of the filter plate 15. After the filter plate 15 is replaced, the extension and retraction of the spring 18 pushes the T-shaped slider 17, placing the limiting rod 19 in the sliding hole 21 to fix the filter plate 15.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
