[0014] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and accompanying drawings are only exemplary descriptions of the technical solution of this utility model, and should not be regarded as the whole of this utility model or as a limitation or restriction on the technical solution of this utility model.

[0015] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a dust suppression device for welding high-altitude prefabricated steel structures, including a dust suppression device body 1; a corrugated pipe 2 is installed at the front end of the dust suppression device body 1, a dust suction chamber 3 is installed at the front end of the corrugated pipe 2, a fixed base 4 is fixedly connected to the bottom end of the dust suppression device body 1, a fixed plate 5 is installed at the bottom end of the fixed base 4, four slots 6 are opened on the surface of the fixed plate 5, a connecting rod 7 is slidably connected inside the slots 6, a limit plate 8 is fixedly connected to the top end of the connecting rod 7, an adjusting plate 9 is fixedly connected to the bottom end of the connecting rod 7, a fixed block 10 is fixedly connected to both the front and rear ends of the fixed plate 5, an adjusting rod 11 is slidably connected inside the fixed block 10, and the opposite surfaces of the fixed plate 5 and the adjusting plate 9 are both open. The device is provided with an arc-shaped groove 12, and limiting grooves 13 are provided on both sides of the adjusting rod 11. Sliding grooves 14 are provided on both sides of the fixing block 10. A sliding rod 15 is slidably connected inside the sliding groove 14 and inserted into the limiting groove 13. A push-pull plate 16 is fixedly connected to the side of the sliding rod 15 away from the fixing block 10. An energy storage spring 17 is sleeved on the surface of the push-pull plate 16. The two sides of the energy storage spring 17 are fixedly connected to the fixing block 10 and the push-pull plate 16 respectively. The inner diameter of the limiting groove 13 is designed to match the size of the sliding rod 15. Guide grooves 18 are provided at the front and rear ends inside the fixing block 10. Guide plates 19 are fixedly connected at the front and rear ends of the adjusting rod 11. The inside of the guide groove 18 is slidably connected to the guide plate 19. Specifically: When the dust suppression device body 1 needs to be installed, the mounting bracket is slid into the arc-shaped groove 12 designed between the fixing plate 5 and the connecting rod 7. At this time, the push-pull plate 16 is pulled outward to pull the sliding rod 15 out of the limiting groove 13, so that the adjusting rod 11 is released from fixation. Then, the connecting rod 7 is pushed upward to make the connecting rod 7 and the fixing plate 5 fit tightly against the surface of the bracket. During the movement of the adjusting rod 11 and the connecting rod 7, the design of the guide groove 18 and the guide plate 19 will form a stable guiding effect to prevent movement and deviation. After the fit is completed, the sliding rod 15 is aligned. The corresponding limiting groove 13 is located, and the elastic force stored in the energy storage spring 17 is released to drive the sliding rod 15 to be stably inserted into the limiting groove 13 that is adapted to it, thereby achieving rapid and stable fixation after the fixing plate 5 and the connecting rod 7 are tightly attached to the bracket; through the design that allows for quick installation and fixation of the dust suppression device body 1 and the mounting bracket, when workers need to use the dust suppression device body 1 at high altitudes, they only need to make simple adjustments to the fixing process to achieve rapid installation and use of the dust suppression device body 1, thereby significantly improving the efficiency and stability of the dust suppression device in steel structure welding.

[0016] Reference Figure 5 As shown in this embodiment: the front end and the rear end of the sliding groove 14 are provided with stop grooves 20, the front end and the rear end of the sliding rod 15 are fixedly connected with stop blocks 21, and the inside of the stop groove 20 is slidably connected with the stop blocks 21. Specifically, by setting the stop groove 20 and the stop block 21, the movement trajectory of the sliding rod 15 inside the sliding groove 14 can be effectively limited, so that the sliding rod 15 will not move excessively during the movement, thereby significantly improving the stability of the connecting rod 7 during the fixing and unfixing process.

[0017] Reference Figure 3 As shown in this embodiment: a return spring 22 is sleeved on the surface of the connecting rod 7, and the top and bottom ends of the return spring 22 are fixedly connected to the limiting plate 8 and the fixing plate 5 respectively; Specifically: By setting the return spring 22, when the dust suppression device body 1 needs to be removed from the mounting bracket, the connecting rod 7 is released from its fixed position. At this time, the elastic force stored in the return spring 22 is released, causing the connecting rod 7 to spring back to the initial adjustment position, thereby achieving quick release of the limiting position between the fixing plate 5 and the connecting rod 7 and the mounting bracket, thus significantly improving the convenience when the dust suppression device body 1 needs to be changed to a different position.

[0018] Reference Figure 3 As shown in this embodiment: a rubber contact plate 23 is installed inside the arc-shaped groove 12; Specifically, by setting the rubber contact plate 23, the arc groove 12 can have greater contact friction when it contacts the surface of the mounting bracket, thereby significantly improving the stability of the fixing plate 5 and the connecting rod 7 during the fixing process with the bracket surface, and making it less likely to shake or shift.

[0019] Working principle: When the dust suppression device body 1 needs to be installed, the mounting bracket is slid into the arc-shaped groove 12 designed between the fixing plate 5 and the connecting rod 7. At this time, the push-pull plate 16 is pulled outward to drive the sliding rod 15 out of the limiting groove 13, so that the adjusting rod 11 is released from the fixation. Then, the connecting rod 7 is pushed upward to make the connecting rod 7 and the fixing plate 5 adhere to the surface of the bracket. During the movement of the connecting rod 7 driven by the adjusting rod 11, the guide groove 18 and the guide plate 19 form a stable guiding effect to prevent movement and deviation. After the adhesion is completed, the sliding rod 15 is aligned with the corresponding limiting groove 13. At this time, the elastic force stored in the energy storage spring 17 is released to drive the sliding rod 15 to be stably inserted into the limiting groove 13 that is adapted to it, thereby achieving rapid and stable fixation after the fixing plate 5 and the connecting rod 7 are adhered to the bracket.

[0020] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
