[0024] 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 scope of protection of the present utility model.

[0025] Please see Figures 1-6 As shown, a welding protection device for steel structure construction includes a device body 1; the left end of the device body 1 is fixedly connected to one end of the connecting line 10, the other end of the connecting line 10 is fixedly connected to the welding gun 2, and a welding protection mechanism is provided on the outside of the device body 1.

[0026] The welding protection mechanism includes a fan outer body 11, which is located at the rear end of the device body 1 near the left side. The front end of the fan outer body 11 is fixedly connected to the device body 1, and the rear end of the fan outer body 11 is fixedly connected to the motor 12. The front end of the motor 12 passes through the fan outer body 11 and is fixedly connected to the rear end of the turbine 13 inside the fan outer body 11. The turbine 13 is circular. The bottom end of the fan outer body 11 is fixedly connected to one end of the first connecting pipe 14.

[0027] During operation, the motor 12 at the rear end of the outer body 11 of the fan is started, which drives the turbine 13 to rotate. When the turbine 13 rotates, it will generate suction, which will draw the harmful gases generated by welding into the outer body 11 of the fan through the second connecting pipe 17 and the suction head 18. Then the outer body 11 of the fan will transport the harmful gases into the first connecting pipe 14.

[0028] Furthermore, the other end of the first connecting pipe 14 passes through the top of the water tank 15 to reach the inside of the water tank 15. The bottom of the water tank 15 is fixedly connected to the top of the fixing plate 16, and the front end of the fixing plate 16 is fixedly connected to the rear end of the device body 1. The fixing plate 16 has a square design.

[0029] During operation, the outer body 11 of the fan transports harmful gases to the inside of the water tank 15 through the first connecting pipe 14. At this time, the water tank 15 is filled with water, and the water submerges the first connecting pipe 14. Thus, the harmful gases discharged from the first connecting pipe 14 can be directly mixed with water for preliminary filtration. The fixing plate 16 is used to fix and support the position of the water tank 15.

[0030] Furthermore, the top of the outer body 11 of the fan is fixedly connected to one end of the second connecting pipe 17, and the other end of the second connecting pipe 17 is fixedly connected to the suction head 18. The suction head 18 is a circular design, and the inner wall of the suction head 18 is fixedly connected to the outer side of the welding gun 2. The connecting line 10 and the outer side of the second connecting pipe 17 are also fixedly connected to multiple sets of limiting blocks 19.

[0031] During operation, the turbine 13 rotates, generating suction. The harmful gases produced during welding are drawn into the fan body 11 through the second connecting pipe 17 and the suction head 18. The limiting block 19 can effectively limit the position of the connecting line 10 and the second connecting pipe 17.

[0032] Furthermore, the rear end of the water tank 15 is fixedly connected to the front end of the drain pipe 20, a first sealing head 21 is sleeved on the outer side of the rear end of the drain pipe 20, and the drain pipe 20 is threadedly connected to the first sealing head 21. The top end of the water tank 15 is fixedly connected to the bottom end of the water injection pipe 22, a second sealing head 23 is sleeved on the outer side of the top end of the water injection pipe 22, and the water injection pipe 22 is threadedly connected to the second sealing head 23.

[0033] During operation, the first sealing head 21 is rotated and removed along the drain pipe 20, thereby draining the wastewater inside the water tank 15. The first sealing head 21 is then reinstalled on the outside of the drain pipe 20. Simultaneously, the second sealing head 23 is rotated, causing it to rotate along the outside of the water injection pipe 22 and detach. Water is then injected into the water tank 15 through the water injection pipe 22.

[0034] Furthermore, the top of the water tank 15 is fixedly connected to the bottom of the exhaust pipe 24, the bottom of the filter box 25 is inserted inside the exhaust pipe 24, and the filter box 25 is slidably connected to the exhaust pipe 24. Two sets of sealing rings 26 are provided near the lower outer side of the filter box 25. The inner wall of the sealing ring 26 is fixedly connected to the outer side of the filter box 25, and the outer side of the sealing ring 26 abuts against the inner wall of the exhaust pipe 24. The sealing ring 26 is made of rubber.

[0035] During operation, harmful gases will be discharged to the outside through the exhaust pipe 24, and during the discharge process, they will be filtered again through the filter box 25. When the filter box 25 needs to be replaced, simply pull the filter box 25 upward, causing it to move upward along the inside of the exhaust pipe 24 until it is completely detached. At the same time, the sealing ring 26 will move upward along the inside of the exhaust pipe 24 until it is detached.

[0036] Furthermore, a caster wheel 28 is also provided at the bottom of the device body 1 near the corner, and the bottom of the device body 1 is fixedly connected to the top of the caster wheel 28, and the top of the device body 1 is fixedly connected to the bottom of the handle 27.

[0037] When in operation, pushing the main body 1 will drive the casters 28 to move, and when it is necessary to lift the main body 1, it is only necessary to grab the handle 27 to lift it.

[0038] Working principle: During welding, the motor 12 at the rear end of the fan outer body 11 is started, driving the turbine 13 to rotate. When the turbine 13 rotates, it generates suction, drawing the harmful gases generated during welding into the fan outer body 11 through the second connecting pipe 17 and the suction head 18. The fan outer body 11 then transports the harmful gases to the water tank 15 through the first connecting pipe 14. At this time, the water tank 15 is filled with water, submerging the first connecting pipe 14. Thus, the harmful gases discharged from the first connecting pipe 14 can be directly mixed with water for preliminary filtration. The harmful gases are then discharged through the exhaust pipe 24, undergoing final filtration again through the filter box 25 during the discharge process. When the filter box 25 needs to be replaced, simply pull it upwards, moving it upwards along the inside of the exhaust pipe 24. When the water tank 15 needs to be replaced, the sealing ring 26 will move upward along the inside of the exhaust pipe 24 until it is completely detached. When the water needs to be replaced, the first sealing head 21 can be rotated and removed along the drain pipe 20 to drain the wastewater inside the water tank 15. The first sealing head 21 is then reinstalled on the outside of the drain pipe 20. At the same time, the second sealing head 23 is rotated, causing it to rotate and detach along the outside of the water injection pipe 22. Water is then injected into the water tank 15 through the water injection pipe 22. The fixing plate 16 is used to fix and support the position of the water tank 15, and the limiting block 19 can effectively limit the position of the connecting line 10 and the second connecting pipe 17. When the device body 1 needs to be moved, the universal wheel 28 can be moved by pushing the device body 1. When the device body 1 needs to be lifted, the handle 27 can be grabbed to lift it.
