DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 As shown, a welding device for the production and processing of protective fences includes a welding box body 1, a box door 2 is provided on the front of the welding box body 1, the box door 2 and the welding box body 1 are connected by a hinge, a transparent plate 3 is inlaid on the box door 2, and a welding assembly 4 is provided on the top wall of the welding box body 1. The welding assembly 4 is a known technology in the existing patent: CN216503082U, which will not be described in detail here. When in use, the pipe fittings of the protective fence are placed in the welding box body 1, the box door 2 is closed, and the welding assembly 4 is started, so that the pipe fittings of the protective fence can be welded, and the transparent plate 3 is convenient for observing the welding condition of the pipe fittings.

[0022] More preferably, a dust reduction box 5 is fixedly installed on the outer surface of the welding box 1, and a ventilation hole connected to the interior of the welding box 1 is opened on the outer surface of the welding box 1. A high-temperature fan 6 is fixedly installed on the upper surface of the dust reduction box 5. One end of the high-temperature fan 6 extraction pipe penetrates into the welding box 1, and the lower end of the high-temperature fan 6 output pipe penetrates into the dust reduction box 5. The lower end of the high-temperature fan 6 output pipe is fixedly connected with a delivery pipe 7, and the delivery pipe 7 is connected to the output pipe. A movable pipe 8 is slidably sleeved on the lower end of the delivery pipe 7. A drawer 9 is provided on the outer surface of the dust reduction box 5, and one side of the drawer 9 slides through the dust reduction box 5 and slides on the bottom wall of the dust reduction box 5. A cooling liquid is poured into the drawer 9, and the lower end of the movable pipe 8 extends into the cooling liquid;

[0023] More preferably, an exhaust pipe 10 is fixedly installed on the upper surface of the dust reduction box 5, the exhaust pipe 10 is connected to the inside of the dust reduction box 5, and a gas filter 11 is provided in the exhaust pipe 10;

[0024] When the welding assembly 4 is welding the protective fence pipe fittings, the high-temperature fan 6 is started and the high-temperature gas generated during the welding of the pipe fittings is extracted. The high-temperature gas is transported to the movable pipe 8 through the delivery pipe 7. Since the lower end of the movable pipe 8 is extended into the cooling liquid, the high-temperature gas transported by the movable pipe 8 enters the cooling liquid, thereby achieving the purpose of cooling the high-temperature gas. The cooled gas is finally discharged from the exhaust pipe 10, and the gas filter 11 purifies the harmful gas. The above method is used to avoid the direct discharge of these high-temperature gases and the impact on the gas filter 1, further ensuring the use effect and service life of the gas filter 11. At the same time, the cooling liquid also absorbs solid impurities in the high-temperature gas, reducing the impurity content on the gas filter 11, and ensuring the long-term use effect of the gas filter 11.

[0025] More preferably, a mounting ring 12 is fixedly sleeved on the outer surface of the conveying pipe 7, and a tension spring 13 is fixedly connected between the lower surface of the mounting ring 12 and the upper surface of the movable pipe 8. The tension spring 13 is movably sleeved on the outer surface of the conveying pipe 7. When the tension spring 13 is not affected by the tension force, the tension spring 13 will generate tension on the movable pipe 8, so that the initial position of the movable pipe 8 is close to the side of the mounting ring 12, so that the bottom of the movable pipe 8 will not hinder the drawer 9 from sliding into the dust reduction box 5.

[0026] More preferably, a gear 15 is rotatably connected to the inner wall of the dust reduction box 5, and a movable groove 14 is provided on the upper surface of the drawer 9 near the gear 15. One side of the movable groove 14 extends out of the side surface of the drawer 9 near the welding box 1, and the lower side of the gear 15 extends into the movable groove 14. A plurality of teeth 16 are fixedly connected to the bottom wall of the movable groove 14. When the drawer 9 slides into the dust reduction box 5, the bottom of the gear 15 extends into the movable groove 14. When most of the drawer 9 extends into the dust reduction box 5, the bottom of the gear 15 contacts the teeth 16, thereby driving the gear 15 to rotate clockwise.

[0027] More preferably, a pushing block 18 is fixedly connected to the outer surface of the movable tube 8, and a pushing rod 17 is fixedly connected to the outer surface of the gear 15 facing the pushing block 18. The pushing rod 17 is arranged on a side away from the center of the gear 15, and a pushing groove 19 is opened on the surface of the side of the pushing block 18 close to the pushing rod 17. One end of the pushing rod 17 close to the pushing block 18 extends into the pushing groove 19 and slides in the pushing groove 19. When the gear 15 rotates clockwise, the pushing rod 17 will form a thrust on the pushing block 18, thereby driving the movable tube 8 to move downward, and at the same time the tension spring 13 is stretched. When the drawer 9 completely slides into the dust reduction box 5, the pushing rod 17 rotates to the lowest point, so that the lower end of the movable tube 8 extends into the cooling liquid. The above structure can automatically control the movable tube 8 to move upward or downward during the drawing and pulling of the drawer 9, thereby avoiding the movable tube 8 from blocking the drawer 9 as much as possible, thereby improving the use effect of the device.

[0028] Working principle: When the welding assembly 4 is welding the protective fence pipe fittings, the high-temperature fan 6 is started and the high-temperature gas generated during the welding of the pipe fittings is extracted. These high-temperature gases are transported to the movable pipe 8 through the delivery pipe 7. Since the lower end of the movable pipe 8 is extended into the cooling liquid, the high-temperature gas transported by the movable pipe 8 enters the cooling liquid, thereby achieving the purpose of cooling these high-temperature gases. The cooled gas is finally discharged from the exhaust pipe 10, and the gas filter 11 purifies the harmful gas.
