Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a three-phase arc welding power supply. Background Art

[0002] Arc welding is a welding method that uses an arc as a heat source to melt the workpiece, welding wire or welding rod to form a weld. It is the most widely used welding method in industrial production. The arc welding power supply is a device that provides the electrical energy required for arc welding and is the core part of the arc welding equipment.

[0003] However, the current arc welding power supply is prone to generate a lot of heat during long-term use. If it is not discharged in time, it is easy to damage the power supply. At the same time, when it is left for a long time, dust and the like are easy to enter the power supply through the heat dissipation holes, affecting the normal operation of the power supply body.

[0004] For example, the publication number "CN213827425U" provides an arc welding power supply device with adjustable working voltage and current. When in use, the user removes the electric welding machine body and moves it to the welding point, releases the wire through the retractable assembly, and then connects the mobile power supply to the electric welding machine body through the wire, so that the electric welding machine body can work normally, thereby improving the applicability of the arc welding power supply device to the welding work point and facilitating welding.

[0005] However, the above device still has the following problems during implementation:

[0006] When in use, the mobile power supply will generate a certain amount of heat. The heat accumulated inside the power supply may easily cause damage during operation and affect normal operation. At the same time, the power supply of the device is installed on the vehicle body. When stored for a long time, dust may easily enter the power supply body and affect subsequent use.

[0026] When the device needs to be used, the base 1 is first moved to a suitable position by means of the handle 12 and the universal wheel 14 and fixed, the shielding block 13 is opened, the power cord is plugged into the power socket 21, the power main body 2 is started to work, and at the same time, the dustproof component 3 is opened so that the dustproof component 3 no longer shields the heat dissipation strip 15, the heat dissipation component in the protective box 11 is started, and the power main body 2 is cooled and dissipated;

[0027] By setting up the dustproof component 3, when the device is not needed, the heat sink 15 can be sealed through the dustproof component 3, so that the interior of the protective box 11 is sealed, preventing dust from entering the protective box 11 through the heat sink 15 for a long time and causing damage to the power supply body 2. At the same time, when it is needed to be used, the heat sink 15 can be exposed by opening the dustproof component 3, so that the protective box 11 can dissipate heat normally.

[0028] For example 2, please refer to Figure 3 The heat dissipation component includes a bellows 4, a plurality of fans are arranged inside the bellows 4, and the air outlet of each fan is toward the power supply body 2. A water cooling pipe 41 is arranged directly below the bellows 4. A fixing plate 16 is fixedly installed on the inner wall of the protection box 11 near the top. The bellows 4 is fixedly installed on the fixing plate 16. The fixing plate 16 is provided with a plurality of vents connected to the fans. The water cooling pipe 41 is fixedly installed on the side of the fixing plate 16 away from the bellows 4. A cold water tank connected to the water cooling pipe 41 is also fixedly installed on the fixing plate 16;

[0029] When the power supply body 2 is running, the cold water tank on the fixed plate 16 is first started, so that the cold water generated by the cold water tank continuously flows through the water cooling pipe 41 to cool down the protection box 11, and then the fan in the bellows 4 is started, and the wind generated by the fan passes through the vents on the fixed plate 16 and is discharged downward, and drives the cold air generated by the water cooling pipe 41 to move downward, so as to cool down the power supply body 2. When the bellows 4 is continuously working, the hot air generated by the operation of the power supply body 2 is continuously blown by the fan and discharged from the heat dissipation strip 15 to further dissipate heat in the protection box 11;

[0030] When in use, the power supply body 2 can be made to operate more stably by combining a plurality of heat dissipation methods, thereby preventing the power supply body 2 from operating faults due to excessively high temperatures in the protection box 11.

[0031] For example 3, please refer to Figure 1 and Figure 4 The dustproof component 3 includes a dustproof plate 31, which is slidably arranged inside the protective box 11. A servo motor 34 is fixedly installed in the inner wall of one side of the protective box 11. The output end of the servo motor 34 is fixedly connected to a first rotating gear 32 through a coupling.

A second rotating gear 35 is also fixedly installed on the side of the dustproof plate 31 close to the first rotating gear 32, and the first rotating gear 32 is meshed with the second rotating gear 35. A second movable rack 36 is also fixedly installed on the side of the dustproof plate 31 close to the second rotating gear 35, and the second movable rack 36 is meshed with the second rotating gear 35;

[0032] When in use, when heat dissipation is required, first start the servo motor 34, so that the servo motor 34 drives the first rotating gear 32 to rotate. When the first rotating gear 32 rotates, the second rotating gear 35 meshing with the first rotating gear 32 rotates at the same time, so that the first moving rack 33 and the second moving rack 36 move upward synchronously under the action of the first rotating gear 32 and the second rotating gear 35, and then the first moving rack 33 and the second moving rack 36 drive the dustproof plate 31 to move upward in the protection box 11, so that the dustproof plate 31 is moved away from the heat dissipation strip 15, so that the heat dissipation strip 15 can dissipate heat normally. When the dustproof plate 31 moves to the top, turn off the servo motor 34 to fix the dustproof plate 31;

[0033] When the use is finished, the servo motor 34 is started again, so that the first rotating gear 32 drives the second rotating gear 35 to rotate in the opposite direction, so that the first moving rack 33 and the second moving rack 36 drive the dustproof plate 31 to move downward, and the heat dissipation strip 15 is closed;

[0034] By setting a movable dustproof plate 31, when in use, by starting the servo motor 34, the first movable rack 33 and the second movable rack 36 can drive the dustproof plate 31 to move upward and move away from the heat dissipation strip 15, so that the protective box 11 can dissipate heat through the heat dissipation strip 15. When use is completed, the servo motor 34 is started again to make the first movable rack 33 and the second movable rack 36 drive the dustproof plate 31 to move downward, so that the heat dissipation strip 15 can be closed, thereby preventing dust from entering the protective box 11 from the heat dissipation strip 15 when not in use and causing damage to the power supply body 2.

[0035] Working principle: When the device needs to be used, first move the base 1 to a suitable position through the handle 12 and the universal wheel 14 and fix it, then open the blocking block 13 and plug the power cord into the power socket 21, start the servo motor 34, so that the servo motor 34 drives the first rotating gear 32 to rotate, so that the first moving rack 33 and the second moving rack 36 move upward synchronously under the action of the first rotating gear 32 and the second rotating gear 35, and then the first moving rack 33 and the second moving rack 36 drive the dustproof plate 31 to move upward in the protective box 11, so that the dustproof plate 31 is removed from the heat dissipation strip 15, so that the heat dissipation strip 15 can dissipate heat normally, when the dustproof plate 31 moves to the top, turn off the servo motor 34 to fix the dustproof plate 31, and start the power supply body 2 to work;

[0036] When the power source body 2 is running, the cold water tank on the fixed plate 16 is turned on, so that the cold water generated by the cold water tank continuously flows through the water cooling pipe 41 to cool down the protection box 11, and then the fan in the bellows 4 is started, and the wind generated by the fan passes through the vents on the fixed plate 16 and is discharged downward, and drives the cold air generated by the water cooling pipe 41 to move downward, so as to cool down the power source body 2. When the bellows 4 is continuously working, the hot air generated by the operation of the power source body 2 is continuously blown by the fan and discharged outward from the heat dissipation strip 15, so as to further dissipate the heat in the protection box 11;

[0037] When use is completed, the servo motor 34 is started again, so that the first rotating gear 32 drives the second rotating gear 35 to rotate in the opposite direction, so that the first moving rack 33 and the second moving rack 36 drive the dustproof plate 31 to move downward, and the heat dissipation strip 15 is closed.
