[0021] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0022] like Figures 1 to 4 As shown, a workshop gas extraction device according to one embodiment of the present invention includes a duct 1, which is installed in the workshop and above a special gas pipeline inside the duct 1. A 4 is fixedly connected to the end of the duct 1 furthest from the workshop. Multiple through slots 11 are formed on the duct 1, and slots 111 are formed on the walls of the through slots 11. A blocking plate 12 is engaged within the slot 111. The workshop gas extraction device also includes a lifting assembly, which can push out the blocking plate 12 within the slot 111.

[0023] When the detection device in the workshop detects a leak of a special gas, the lifting device can push the corresponding blocking plate 12 out of the slot 111, thereby drawing air from the vicinity of the leak into the workshop and reducing the concentration of the special gas in the workshop.

[0024] Specifically, the lifting assembly includes a slide rail 2, on which an electronic slider 21 is slidably connected. A fixing frame 3 is welded to the electronic slider 21, and a hydraulic cylinder 31 and an oil pump 33 are mounted on the fixing frame 3. The electronic slider 21 is wirelessly connected to the detection device and can receive signals from the detection device indicating the specific leak location. It then moves along the channel 11, moving to the channel 11 closest to the leak location of the special gas. Then, the oil pump 33 starts, which pushes out the blockage plate 12 in the slot 111. In this way, during operation, only the channel 11 at the position where the blockage plate 12 is pushed out is a passage, ensuring ventilation capacity and preventing the airflow velocity in other parts of the workshop from increasing, thus reducing the mixing speed of the special gas and air in the workshop.

[0025] Further, the hydraulic cylinder 31 comprises a cylinder barrel and a piston rod, the piston rod is provided with a plug groove 32 at one end away from the cylinder barrel, and the air pipe 1 is integrally formed with a fixing ring 121 matched with the plug groove 32. When the piston rod is in the jacking baffle plate 12, the fixing ring 121 can be clamped in the plug groove 32 and cannot be separated from the piston rod due to the influence of wind, so that the baffle plate 12 cannot block the air pipe 1 and the air exhaust effect is affected.

[0026] Further, the plug groove 32 is provided with a second position sensor 321, and the baffle plate 12 is provided with a first position sensor 122 matched with the second position sensor 321. Through the position sensing of the second position sensor 321 and the first position sensor 122, the hydraulic cylinder 31 can be located directly below the baffle plate 12, so that the fixing ring 121 can be clamped with the second position sensor 321.

[0027] Preferably, the fixing ring 121 is a magnetic ring. When the fixing ring 121 is in the second position sensor 321, it can be magnetically attracted to the bottom wall of the second position sensor 321.

[0028] Meanwhile, the sliding rail 2 is welded with a mounting frame 22 matched with the electronic sliding block 21, the mounting frame 22 is provided with a conductive block 23, and the electronic sliding block 21 is integrally formed with a connecting column 211 matched with the conductive block 23. Specifically, the conductive block 23 sends electromagnetic signals outward under the action of electricity, and the connecting column 211 receives the electromagnetic signals and converts them into electric current, so as to realize wireless charging of the electronic sliding block 21 and ensure that the electronic sliding block 21 is always powered.

[0029] Compared with the prior art, the workshop gas extraction device can extract gas in the workshop at a fixed point, effectively reduce the gas flow speed in the non-leakage area, slow down the mixing speed of special gas and air in the workshop, increase the safety time of personnel escaping from the workshop, and further improve the safety of workshop operation and the life safety guarantee of personnel.
