Description

Technical Field

[0004] When the above patent is working, the water inlet pump is turned on to guide the water source inside the water tank into the nozzle through the water inlet pipe and the diversion pipe. The nozzle sprays the cooling box to cool it down. Under the action of gravity, the water source flows down along the outer wall of the cooling box and gathers at the bottom of the cooling box. Then, it flows back to the water tank through the return pipe through the water outlet pump. The cooling fan on the outer wall of the water tank cools the liquid inside the water tank, forming a water flow circulation to achieve cooling treatment of the transformer.

[0005] However, in actual application, since the water cooling system of the above patent involves multiple pipe connections and sealing parts, such as the sealing groove and sealing protrusion between the cooling box and the cooling box, the connection between the water inlet pipe and the water inlet pump, the connection between the return pipe and the water outlet pump, etc., if there is a problem with the sealing of these parts, there will be a risk of water leakage. Leakage will not only affect the heat dissipation effect, but also cause damage to the welding machine and surrounding equipment. After long-term use, the seals may age or be damaged, causing water leakage. When water leakage occurs, the device cannot stop the water supply in time, resulting in increased water accumulation in the heat dissipation device, and there is a risk of leakage to the power supply, which is not safe enough.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] like Figures 1-6 As shown, a heat dissipation device for an electric welding machine includes a mounting shell 1 and a partition 5 fixedly connected to the mounting shell 1, and a transmission assembly 2 is provided on the mounting shell 1;

[0035] The transmission assembly 2 includes a liquid receiving tank 21, which is slidably connected to the partition 5. The partition 5 is fixedly connected to a first limiting rod 23 and a second limiting rod 24. The liquid receiving tank 21 is fixedly connected to a spring 22. A lifting tank 26 is slidably connected to the side of the mounting shell 1 close to the second limiting rod 24. The lifting tank 26 is fixedly connected to a fixed shaft 27. The fixed shaft 27 is fixedly connected to a first connecting rod 28. The end of the first connecting rod 28 away from the fixed shaft 27 is fixedly connected to a first rotating shaft 29. The first rotating shaft 29 is fixedly connected to a second connecting rod 210. The second connecting rod 211 is fixedly connected to the first rotating shaft 29. The connecting rod 210 is fixedly connected to a universal joint 212, and the universal joint 212 is fixedly connected to a lifting rod 211. The lifting rod 211 is fixedly connected to a sliding plate 215 on the side away from the universal joint 212. The partition plate 5 is fixedly connected to a first water pump 214, and the first water pump 214 is fixedly connected to a first water pipe 25. The end of the first water pipe 25 away from the first water pump 214 is fixedly connected to a nozzle 44. The first water pump 214 is fixedly connected to a first water pumping pipe 213, and the first water pumping pipe 213 is fixedly connected to the sliding plate 215. A slot is formed on the mounting shell 1.

[0036] In the present invention, in order to solve the problem that the water cooling system is prone to water leakage, when water seepage occurs around the first water pump 214, the water leaks into the liquid receiving tank 21. Under the action of the weight of the accumulated water, the liquid receiving tank 21 is blocked by the second limit rod 24 and the first limit rod 23 and deformed, so that the cooling water in the liquid receiving tank 21 flows to the lifting tank 26 through the guide groove. As the cooling water in the lifting tank 26 increases, its descent drives the movement of related structures, and finally the first pumping pipe 213 is lifted away from the cooling water surface, completing the water cut-off operation, effectively avoiding the risk of continuous increase of water accumulation in the heat dissipation device due to leakage and leakage to the power supply, greatly improving the safety of use, and solving the problem in the background technology that the existing technology cannot stop the water supply in time when leakage occurs, which may cause losses.

[0037] Further, such as Figures 2 to 5As shown, the first rotating shaft 29 is rotatably connected to the partition 5, the sliding plate 215 is slidably connected to the partition 5, and a spring piece 4 is fixedly connected to the side of the mounting shell 1 away from the partition 5. The first water pipe 25 is fixedly connected to the spring piece 4, and the end of the spring 22 away from the liquid receiving bin 21 is fixedly connected to the partition 5. An arc-shaped piece is fixedly connected to the mounting shell 1, and the end of the liquid receiving bin 21 away from the spring 22 is slidably connected to the arc-shaped piece in the mounting shell 1. By providing the spring piece 4, when in use, an iron shell can be wrapped around the welding machine through the slot on the mounting shell 1 and then inserted between the spring pieces 4. The welding machine is fixed by the elastic force of the spring piece 4. Afterwards, the cooling water on the side of the partition 5 close to the sliding plate 215 is sprayed onto the iron shell of the welding machine through the nozzle 44 by starting the first water pump 214. Afterwards, the cooling water flows through the iron shell to the bottom of the inside of the mounting shell 1, and the cooling water is pumped into the welding machine by starting the second water pumping pipe 41. The water is pumped back to the side of the mounting shell 1 close to the sliding plate 215. The function of the partition 5 is to isolate the cooling water and complete the cooling of the electric welding machine. When water seepage occurs around the first water pump 214, it will leak into the liquid receiving tank 21. The liquid receiving tank 21 is driven to slide downward under the weight of the accumulated water. It is first stopped by the second limiting rod 24 set on the upper side, and the liquid receiving tank 21 bends. Thereafter, the downwardly bent side is stopped by the first limiting rod 23. The cooling water on the liquid receiving tank 21 flows into the lifting tank 26 through the guide groove on the liquid receiving tank 21. As the cooling water in the lifting tank 26 accumulates, the lifting tank 26 descends and drives the first connecting rod 28 and the first rotating shaft 29 to rotate through the fixed shaft 27, so that the second connecting rod 210 is tilted upward, so that the lifting rod 211 drives the first water pumping pipe 213 to rise, so that the end of the first water pumping pipe 213 away from the lifting tank 26 gradually moves away from the cooling water surface, completing the water cut-off.

[0038] A second water pump 42 is fixedly connected to the bottom of the inner wall of the mounting shell 1 on a side away from the partition 5. By providing the second water pump 42, cooling water can be pumped back to the side of the mounting shell 1 near the sliding plate 215 during use, thereby realizing the circulation of cooling water.

[0039] The second water pump 42 is fixedly connected to a second water extraction pipe 41, and the second water extraction pipe 41 is fixedly connected to a second water delivery pipe 43. One end of the second water delivery pipe 43 away from the second water pump 42 is fixedly connected to the partition 5. By providing the second water extraction pipe 41, the cooling water can be returned through the second water extraction pipe 41 during use, completing the cooling water circulation and reducing waste.

[0040] A fan 3 is installed on the mounting shell 1. A groove is provided on the mounting shell 1. The fan 3 is installed in the groove on the mounting shell 1. The fan 3 is installed on one end of the mounting bin for holding cooling water. By providing a groove on the fan 3 and installing the fan 3 on the groove on the mounting bin, heat dissipation of the cooling water is achieved and the heat dissipation effect of the coolant is improved.

[0041] The above solution also has the problem that when the liquid receiving tank 21 is used, the coolant may spill out of the liquid receiving tank 21 when pouring water into the lifting tank 26. Figure 3 、 Figure 4 As shown, a guide groove is provided on one side of the liquid receiving tank 21 close to the lifting tank 26. By providing the guide tank, when in use, the coolant on the liquid receiving tank 21 can be introduced into the lifting tank 26 through the guide groove, which greatly reduces the problem of the coolant spilling outside the liquid receiving tank 21.

[0042] Working principle: Figure 1 - Figure 6 As shown, first, the welding machine wrapped in the iron shell is inserted between the shrapnel 4 by using the slot on the mounting shell 1. The elastic force of the shrapnel 4 can fix the welding machine. After starting the first water pump 214, the cooling water on the side of the partition 5 close to the sliding plate 215 will be transported to the nozzle 44 through the first water pipe 25. The nozzle 44 sprays the cooling water onto the iron shell of the welding machine. The cooling water flows along the iron shell to the bottom of the mounting shell 1, thereby cooling the welding machine. When water seepage occurs around the first water pump 214, the water will leak into the liquid storage tank 21. The liquid storage tank 21 slides downward under the weight of the accumulated water, and is first held and bent by the second limit rod 24. Then, under the action of the first limit rod 23, its downwardly bent side is blocked, and the cooling water on the liquid storage tank 21 flows to the lifting tank 26 through the guide groove. As the cooling water in the lifting tank 26 increases, the lifting tank 26 descends, and the fixed The shaft 27 drives the first connecting rod 28 to move, and the first connecting rod 28 drives the first rotating shaft 29 to rotate, so that the second connecting rod 210 is tilted upward, and the second connecting rod 210 drives the lifting rod 211 to rise through the universal joint 212, thereby driving the first water pumping pipe 213 to rise, so that the end of the first water pumping pipe 213 away from the lifting chamber 26 gradually moves away from the cooling water surface, completing the water cut-off operation to prevent more water from leaking into the area where a fault may occur. In addition, a second water pump 42 is provided. After starting the second water pump 42, the cooling water on the bottom of the inner wall of the mounting shell 1 away from the partition 5 is pumped out through the second water pipe 41, and is re-delivered to the side of the mounting shell 1 near the sliding plate 215 through the second water supply pipe 43, thereby realizing the circulation of cooling water and reducing waste. The fan 3 on the mounting shell 1 is installed in the groove, which can dissipate heat to the area on the mounting shell 1 where cooling water is held, thereby improving the heat dissipation effect of the coolant.
