Description

Technical Field

[0001] This invention relates to the field of finned radiator inner wall treatment technology, and more particularly to a paint filling device for the inner wall of finned radiators. Background Technology

[0002] A transformer finned radiator includes two manifolds and multiple fins connecting them. Each fin has a cavity that connects the two manifolds. During operation, high-temperature liquid enters through the inlet of one manifold, is cooled by the fins, and exits through the outlet of the other manifold, thus creating a heat dissipation channel within the radiator. After assembly and welding, the inner wall of the heat dissipation channel and the outer surface of the radiator need to be painted.

[0003] Currently, the internal wall treatment of radiators is hot oil flushing. However, this method, due to its circulating process, leads to continuous contamination of the transformer oil after processing a certain number of radiators. This results in problems such as increased dielectric loss, requiring frequent filtration or replacement of the transformer oil, which is costly and makes it difficult to maintain internal cleanliness. To achieve cleanliness of the radiator's internal wall, internal coating is employed. Due to the radiator's unique structure, common coating methods such as dip coating, spraying, and brushing are not feasible. The commonly used coating method is potting, where existing technology typically uses oil paint for the radiator's internal wall. However, oil paint itself is highly polluting, thus requiring a low-polluting paint solution for coating the radiator's internal wall. Developing a suitable potting device for radiator internal walls is also necessary to ensure coating effectiveness while reducing the skill requirements of workers. Traditional manual potting operations are unsafe and inefficient, requiring operators to be constantly present during the potting process, creating a harsh environment that can harm workers' health.

[0004] Based on this, a paint filling device for the inner wall of a plate radiator is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a paint-filling device for the inner wall of a plate-type heat sink in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A paint-filling device for the inner wall of a finned radiator includes a support frame, a connecting platform connected to one side of the support frame, a sleeve block rotatably connected to the support frame via a shaft, an oscillating rod rotatably connected to the sleeve block, a flipping gear and a clamping cover respectively connected to both ends of the oscillating rod, a screw connected to the clamping cover, and a clamping plate connected to one end of the screw. The connecting platform is connected to a rotary motor via a motor clamp. The output end of the rotary motor is connected to a rotating disk.

A rotating rod is rotatably connected to the rotating seat. A first bevel gear is connected to the rotating rod. An upper plate is connected to the upper end of the rotating rod. A trapezoidal block is connected to the upper plate. A lower plate is fitted onto the rotating rod. A rack is connected to the lower plate. A lifting mechanism is provided on one side of the rotating rod. The lifting mechanism can first lower the height of the lower plate, allowing the water-based paint inside the radiator to vibrate, and then raise the height of the lower plate, allowing the radiator to flip and fully fill the interior of the radiator with paint.

[0007] Preferably, the oscillating rod is provided with a ring structure, and the sleeve block is disposed between the ring structures.

[0008] Preferably, a connecting cover is fitted onto the oscillating rod, and the connecting cover is rotatably connected to the outside of the sleeve block.

[0009] Preferably, the rotating disk has a connecting groove, the pointer is connected to the connecting groove by a screw, and one end of the pointer is sleeved on the output shaft of the rotating motor.

[0010] Preferably, the first bevel gear and the second bevel gear mesh with each other.

[0011] Preferably, the rotating rod has a groove, and the lower plate is slidably connected to the groove of the rotating rod, with the inner ring of the lower plate fitting into the groove of the rotating rod.

[0013] Preferably, one end of the lifting frame is sleeved on the rotating rod, the lifting frame is slidably connected to the fixed frame, and a torsion spring is provided at the connection between the deflecting component and the deflecting shaft.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This application adopts a trapezoidal block structure to limit the oscillating rod structure, so that when the trapezoidal block rotates, the oscillating rod can drive the plate heat sink to vibrate, which promotes the uniform distribution of water-based paint inside the heat sink, improves the uniformity of the paint film inside the heat sink, reduces the dead corners of water-based paint coverage inside the heat sink, and improves the painting quality of the heat sink.

[0015] 2. This application adopts a rack and pinion structure, which drives the rotating gear to rotate, thereby causing the radiator to rotate. This ensures that the water-based paint inside the radiator can cover all parts of the radiator. Combined with the structural oscillation process, it improves the paint filling efficiency of the radiator. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-5 The present invention provides a technical solution: The painting device for the inner wall of a finned radiator includes a support frame 1. The support frame 1 makes the radiator structure more stable during painting. A connecting platform 2 is connected to one side of the support frame 1. A sleeve block 11 is rotatably connected to the support frame 1 via a shaft. A symmetrical connection is made to the outside of the sleeve block 11. An oscillating rod 19 is rotatably connected to the sleeve block 11. The sleeve block 11 is fitted onto the outside of the oscillating rod 19. A flip gear 15 and a clamping cover 12 are respectively connected to both ends of the oscillating rod 19. The radiator is connected to one end of the clamping cover 12 of the oscillating rod 19. A screw 13 is connected to the clamping cover 12. A clamping plate 14 is connected to one end of the screw 13. Since the structure of the screw 13 is adjustable, the clamping plate 14 can clamp finned radiators of different sizes. This device can meet the painting needs of radiators of different sizes. Connecting platform 2 is connected to rotary motor 4 via motor clamp 3. Motor clamp 3 improves the connection of rotary motor 4. Rotary disk 9 is connected to the output end of rotary motor 4. Side block 24 and bevel gear 18 are connected to rotary disk 9. One side of side block 24 is set as an inclined surface to facilitate pushing one end of lifting frame 22 to rise in height when it rotates. Pointer 23 is connected to rotary disk 9. Pointer 23 plays the role of turning one end of deflection component 27. Rotating seat 5 is connected to connecting platform 2. Rotating rod 20 is rotatably connected to rotating seat 5. The rotation stability of rotating rod 20 is improved by setting rotating seat 5. Bevel gear 6 is connected to rotating rod 20. The planes of bevel gear 6 and bevel gear 18 are perpendicular to each other. The upper end of rotating rod 20 is connected to The upper plate 8 is connected to a trapezoidal block 16. By changing the number of trapezoidal blocks 16, the oscillation frequency of the oscillating rod 19 can be changed. The more trapezoidal blocks 16 there are, the faster the oscillation frequency of the oscillating rod 19 will be. A lower plate 7 is fitted on the rotating rod 20. A rack 17 is connected to the lower plate 7. The number of rack 17 structures is positively correlated with the flipping frequency of the oscillating rod 19. A trapezoidal block 16 must be set above the rack 17, but a rack 17 may not be set below the trapezoidal block 16. A lifting mechanism is set on one side of the rotating rod 20. The lifting mechanism can first drive the lower plate 7 to drop, so that the paint inside the radiator can oscillate. Then it can drive the lower plate 7 to rise, so that the radiator can flip and fully fill the inside of the radiator with paint.

[0020] Specifically, such as Figure 1 and Figure 3 As shown, an annular structure is provided on the oscillating rod 19, and the sleeve block 11 is disposed between the annular structures. The annular structure limits the connection position of the sleeve block 11 on the oscillating rod 19, preventing structural displacement and improving the stability of the paint filling process.

[0021] Specifically, such as Figure 1 and Figure 3 As shown, a connecting cover 10 is sleeved on the oscillating rod 19. The connecting cover 10 is rotatably connected to the outside of the sleeve block 11. The stability of the operation and coordination between the structures is ensured by setting the connecting cover 10.

[0022] Specifically, such as Figure 5 As shown, a connecting groove 25 is provided on the rotating disk 9. The pointer 23 is connected to the connecting groove 25 by screws. One end of the pointer 23 is sleeved on the output shaft of the rotary motor 4. The connecting groove 25 is semi-circular. By changing the connection position of the screw on the pointer 23, the connection position of the pointer 23 on the rotating disk 9 can be changed, thereby changing the distance between one end of the pointer 23 and the side block 24, so as to control the frequency of the lifting frame 22 to move up and down, making the structure adjustable.

[0023] Specifically, such as Figure 2 As shown, bevel gear 6 and bevel gear 18 mesh with each other. By utilizing the meshing state between the structures, bevel gear 18 drives bevel gear 6 to rotate.

[0024] Specifically, such as Figure 2 and Figure 5 As shown, a groove is provided on the rotating rod 20, and the lower plate 7 is slidably connected to the groove of the rotating rod 20. The inner ring of the lower plate 7 fits into the groove of the rotating rod 20. By setting the groove structure, the lower plate 7 can slide up and down on the rotating rod 20, and its structure can rotate with the rotating rod 20. On the contrary, one end of the lifting frame 22 is sleeved on the rotating rod 20, that is, one end of the lifting frame 22 can only slide on the rotating rod 20.

[0025] Specifically, such as Figure 5 As shown, the lifting mechanism includes a lifting frame 22, and a fixed frame 21 is connected to the motor clamp 3. The fixed frame 21 is used to limit the lifting frame 22. Part of the structure of the lifting frame 22 can slide at one end of the fixed frame 21. A deflection shaft 26 is connected to the lifting frame 22, and a deflection member 27 is rotatably connected to the deflection shaft 26. Both ends of the deflection member 27 are hook-shaped structures. One hook-shaped structure can be fastened to the fixed frame 21 to prevent the height of the lifting frame 22 from falling, while the other hook-shaped structure can contact one end of the pointer 23, thereby driving the deflection member 27 to deflect against the torsion spring and thus canceling the fastening state between one end of the deflection member 27 and the fixed frame 21.

[0026] Specifically, such as Figure 5 As shown, one end of the lifting frame 22 is sleeved on the rotating rod 20, and the lifting frame 22 supports the lower plate 7. The lower surface of the lower plate 7 is in contact with the upper surface of the lifting frame 22. The lifting frame 22 is slidably connected to the fixed frame 21. A torsion spring is provided at the connection between the deflecting component 27 and the deflecting shaft 26. The torsion spring structure ensures the stability of the connection between one end of the deflecting component 27 and the fixed frame 21.

[0027] In summary, the paint-filling device for the inner wall of a finned radiator provided in this embodiment requires the operator to open the radiator, add water-based paint, and then seal the radiator structure when paint filling is needed inside the radiator. This operation must ensure the airtightness of the radiator structure to prevent leakage of the water-based paint when the radiator is moved, ensuring the stability and airtightness of the structure during subsequent paint filling operations. The paint filling here refers to the process of fully covering the inside of the radiator with water-based paint. This specific addition operation of water-based paint is relatively advanced nowadays. The technology is mature, so only a brief description is given here. It is sufficient to ensure that the water-based paint fills half of the space inside the radiator. A single-component water-based paint is used as the paint for treating the inner wall of the plate radiator. This type of paint has the characteristics of long activation period and will not cause paint waste due to cross-linking curing reaction. Moreover, water-based paint is more environmentally friendly than ordinary paint and is more friendly to the health of employees. Then, the radiator is placed between the clamping covers 12, and the screw 13 is rotated to ensure that the clamping plates 14 on both sides of the radiator can clamp the radiator and ensure that the radiator structure remains stable when the paint film is formed. The operator can then move away from the device and remotely control the rotary motor 4 to rotate. The rotary motor 4 drives the rotary disk 9 to rotate, and the pointer 23 connected to the rotary disk 9 moves one end of the deflector 27, causing the deflector 27 to rotate around the deflection shaft 26. Since the other end of the deflector 27 is fastened to the fixed frame 21, and a torsion spring structure is provided at the connection between the deflector 27 and the deflection shaft 26, when the pointer 23 moves one end of the deflector 27, the torsion spring is subjected to force and rotates, and one end of the deflector 27 changes from being fastened to the fixed frame 21 to being disengaged. At this time, the lifting frame 22 descends horizontally under the limiting action of the fixed frame 21. As the lower plate 7 moves with the height of the lifting frame 22... As the bevel gear 18 rotates with the rotating disk 9, it drives the bevel gear 6 to rotate, thereby causing the upper disk 8 to rotate. When the trapezoidal block 16 connected to the upper disk 8 rotates to contact the oscillating rod 19, it can achieve the effect of pressing the oscillating rod 19 downward. In the initial state, the oscillating rod 19 is connected to a heat sink structure at one end, and the end of the oscillating rod 19 connected to the flipping gear 15 will be raised. The trapezoidal block 16 plays the role of pressing the raised end. When the oscillating rod 19 swings up and down, it achieves the effect of oscillating the heat sink, ensuring that the water-based paint inside is fully oscillated in the device, improving the coverage of the water-based paint, and reducing the dead corners of the paint film in the device. When the rotating disk 9 rotates until the side block 24 abuts against one end of the lifting frame 22, it will push the lifting frame 22 to rise. At this time, the deflecting component 27 connected to the lifting frame 22 will rotate under the action of the torsion spring, thereby completing the state in which one end of the deflecting component 27 is fastened to the fixed frame 21, restricting the lifting frame 22 from falling. At this time, the lower plate 7 structure is supported by the lifting frame 22 structure, causing the lower plate 7 to rise. At this time, when the rotating rod 20 rotates, when the trapezoidal block 16 presses the oscillating rod 19, it forces the flipping gear 15 connected to the oscillating rod 19 to engage with the rack 17. The rack 17 and trapezoidal block 16 are arranged in an arc shape. The rotating rack 17 can drive the flipping gear 15 to rotate, which in turn drives the oscillating rod 19 to rotate. This process achieves the effect of flipping the radiator, ensuring that the radiator can oscillate at any angle during paint filling. This improves the uniformity of paint film coverage inside the radiator, avoids dead corners and water-based paint accumulation, and ensures the quality and efficiency of paint filling inside the radiator. It also facilitates subsequent drying of the paint film inside the radiator and improves subsequent drying efficiency.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
