Description

Technical Field

[0001] This utility model relates to the field of power supply voltage regulation technology, specifically a voltage regulation device for plasma cutting power supply. Background Technology

[0002] Plasma arc cutting involves passing a mixture of gases through a high-frequency electric arc. The gases can be air, or a mixture of hydrogen, argon, and nitrogen. The high-frequency electric arc "decomposes" or ionizes some of the gases into basic atomic particles, thus producing "plasma."

[0003] Patent CN215222853U discloses a voltage stabilizing device for a plasma cutting power supply. It includes a voltage stabilizing box, a power supply body, and a voltage regulator. The voltage stabilizing box has pulleys at all four corners of its lower surface, and the inside of the voltage stabilizing box has a storage chamber and a cooling chamber. The storage chamber has two support plates, and each of the two support plates has multiple slots. This device can move the box to a designated position according to the cutting position. When stored, the box is sealed to reduce dust entry. During operation, it can automatically select the heat dissipation method based on the heat generated by the power supply and the voltage regulator, saving energy. It is more flexible in use and has a better heat dissipation effect, which can effectively protect the equipment.

[0004] However, the cooling air outlet of this device is located on the upper side wall of the storage chamber. Due to the phenomenon of cold air sinking, the cold air discharged from the outlet will first slowly sink and squeeze out the hot air generated by the power supply before filling the entire storage chamber to cool the power supply and improve heat dissipation. Furthermore, after the temperature of the storage chamber drops, the cold air will continuously be discharged from the side of the voltage regulator box, which not only reduces the heat dissipation efficiency but also wastes the cold air resources generated. To address this issue, a voltage regulator for plasma cutting power supplies is proposed to solve the problem that existing voltage regulators cannot quickly and energy-efficiently cool and regulate the power supply.

[0015] (III) Beneficial Effects

[0016] 1. The voltage stabilizing device of this plasma cutting power supply uses an air pump to draw heat from the inside of the voltage stabilizing box into the absorption pipe through the air guide groove, and then into the cooler through the return pipe. After cooling, the heat is introduced into the exhaust plate through the exhaust pipe, and finally blown evenly from the top through the exhaust slot holes to the inside for cooling and heat dissipation. During the process, the cold air sinks and compresses the hot air, which, together with the suction, quickly replaces the air inside the voltage stabilizing box, ensuring the cooling and heat dissipation effect. This solves the problem that existing voltage stabilizing devices cannot quickly dissipate heat and stabilize the power supply.

[0017] 2. The voltage regulator of this plasma cutting power supply allows air entering from the outside, as well as air forced into the air guide groove by suction and the downward pressure of cold air, to pass through a filter plate. This filters the air introduced into the cooler, preventing dust from entering the return pipe, cooler, and other structures and causing blockages that could affect subsequent cooling and voltage regulation. Furthermore, the filter plate can be pulled out of the mounting slot for cleaning using the slot opening, facilitating the normal operation and use of the voltage regulator of this power supply.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figure 1-4 A voltage stabilizing device for a plasma cutting power supply includes a voltage stabilizing box 1. The inner cavity of the voltage stabilizing box 1 is provided with two placement plates 2. The top of the lower and upper placement plates 2 are respectively provided with a cutting power supply 3 and a voltage regulator 4. The top of the voltage stabilizing box 1 is provided with an air pump 5 and a cooler 6. One end of the voltage stabilizing box 1 is provided with a return pipe 7. The bottom inner wall of the voltage stabilizing box 1 is provided with an absorption pipe 8. The top of the absorption pipe 8 is provided with an exhaust pipe 9. The top of the inner cavity of the voltage stabilizing box 1 is fixedly connected with an exhaust plate 10. The exhaust plate 10 is hollow inside and has several exhaust slots 11 through it at the bottom. The top inner wall of the voltage stabilizing box 1 is provided with an exhaust pipe 12. The bottom of the inner cavity of the voltage stabilizing box 1 is provided with a guide groove 20.

[0025] Furthermore, the two placement plates 2 are staggered in the inner cavity of the pressure stabilizing box 1, and the cooler 6 is interconnected with the return pipe 7 and the air pump 5.

[0026] Furthermore, the exhaust pipe 12 is interconnected with the inner cavity of the air pump 5 and the exhaust plate 10, the return pipe 7 is interconnected with the absorption pipe 8, and the suction pipe 9 is interconnected with the air guide groove 20.

[0027] Furthermore, a fan 13 is installed on one side of the voltage stabilizer box 1. The fan 13 is connected to the inner cavity of the voltage stabilizer box 1. When the internal temperature of the voltage stabilizer box 1 is not high, the fan 13 can be turned on to accelerate the airflow inside the voltage stabilizer box 1 and improve the heat dissipation effect. At the same time, when a lot of heat is generated inside the voltage stabilizer box 1 due to the operation of the power supply 3 or the voltage stabilizer 4, the fan 13 can be turned on first to exhaust most of the heat, and then the fan 13 can be turned off. Then the air pump 5 can be turned on to perform the circulation operation of drawing in and expelling cold air, thereby reducing the temperature of the air introduced into the cooler 6 and further reducing energy consumption.

[0028] Furthermore, the bottom of the inner cavity of the pressure stabilizing box 1 is provided with mounting grooves 14 at both ends, and the inner cavity of the mounting groove 14 is provided with a filter plate 15, which is attached to the top of the air guide groove 20.

[0029] Furthermore, there is a frictional force between the mounting groove 14 and the filter plate 15 that allows them to remain relatively stationary. The top of the filter plate 15 has a slot 16. The air entering from the outside, as well as the air squeezed into the air guide groove 20 by suction and the downward pressure of the cold air, will pass through the filter plate 15. This filters the air introduced into the cooler 6, preventing dust from entering the return pipe 7, cooler 6, and other structures and causing blockages, which would affect subsequent cooling, heat dissipation, and voltage stabilization. The slot 16 can also be used to pull the filter plate 15 out of the mounting groove 14 for cleaning, which facilitates the normal operation and use of the voltage stabilization device of this power supply.

[0030] Furthermore, L-shaped fixing strips 17 are fixedly connected to both ends of the inner cavity wall of the voltage regulator box 1. The placement plate 2 is located on the top of the L-shaped fixing strip 17 and can slide freely. A limit pin 18 is provided through the top of the L-shaped fixing strip 17. The limit pin 18 contacts the placement plate 2. A handle 19 is fixedly connected to the bottom of the placement plate 2. When the limit pin 18 is pulled out from the L-shaped fixing strip 17, the placement plate 2 will contact the limit. With the handle 19, the placement plate 2, along with the power supply 3 and the voltage regulator 4, can be pulled out for easy maintenance and cleaning.

[0031] Working Principle: When using the voltage stabilization device of this plasma cutting power supply, the voltage regulator 4 stabilizes the cutting power supply 3. If a lot of heat accumulates in the voltage stabilization box 1 due to operation, the air pump 5 is turned on. The heat inside the voltage stabilization box 1 is drawn from the air guide groove 20 into the absorption pipe 9 through the suction pipe 8, and after passing through the return pipe 7 into the cooler 6 for cooling, it is guided into the exhaust plate 10 through the exhaust pipe 12. Finally, it is blown evenly from the top into the interior from the exhaust slot hole 11 to cool down and dissipate heat. During the process, the cold air sinks and compresses the hot air, which, together with the suction, quickly replaces the air inside the voltage stabilization box 1, ensuring the cooling and heat dissipation effect. This solves the problem that existing voltage stabilization devices cannot quickly dissipate heat and stabilize the power supply. As more and more cold air is inside the voltage stabilization box 1, the temperature of the air circulating from the air guide groove 20 will also become lower and lower. That is, the temperature of the air entering the cooler 6 is lower than that of the outside, thereby reducing the energy consumption of the cooler 6 and thus achieving the purpose of reducing energy consumption.
