When the height of the second column 3 needs to be adjusted, the pressing spring buckle is only needed to be pressed down, so that the second column 3 moves up and down relative to the first column 1, and the pressing spring buckle pops out when it reaches the desired clamping hole, thereby fixing the height of the second column.

[0038] The opposite side of the two second columns 3 is provided with a smoke curtain 4, and the smoke curtain 4 is fixedly connected with one of the second columns 3. By arranging the smoke curtain 4, the use requirement of smoke blocking is effectively met, the sealing performance is superior, the smoke leakage phenomenon is not easy to occur, and the installation is convenient and fast.

[0039] The top end of the two second columns 3 is provided with a guide structure connected with the smoke curtain 4 for guiding the smoke curtain 4 to unfold and block smoke. By arranging the guide structure, it can be ensured that the smoke curtain 4 can move along a predetermined track when unfolded, avoiding the smoke leakage phenomenon caused by irregular movement of the smoke curtain 4.

[0040] In order to further improve the fireproof performance, the smoke and dust prevention device further comprises a fireproof cloth 8 arranged below the smoke curtain 4 and connected with the smoke curtain 4 through the fireproof glue 7. By arranging the fireproof glue 7, the movement of the smoke curtain 4 caused by the existing cable and pipeline can be effectively prevented, and the fireproof cloth 8 can be bonded by the fireproof glue 7 after the closed smoke curtain 4 is disconnected by the staff, so as to ensure the normal use of the pipeline. Further, the bottom end of the fireproof cloth 8 is fixedly connected with a movable magnet 9, and the movable magnet 9 is magnetically attracted to the enclosure 2. By arranging the movable magnet 9, the bottom end of the fireproof cloth 8 can be sealed with the enclosure 2 while the smoke curtain 4 is stably and horizontally moved.

[0041] The guide structure comprises first and second mounting seats 11 and 12, mounting shafts 13, fixed pulleys 14 and guide ropes 15.

[0043] Further, in order to improve the stability of the operation of the smoke screen, the guide structure further comprises a guide rail 16 and a guide block 17, the guide rail 16 is arranged between the two second vertical columns 3 and is fixedly connected with the second vertical columns 3. The guide block 17 is slidably arranged on the guide rail 16 and is connected with the guide rope 15 and the smoke screen 4 respectively. When the user pulls the guide rope 15, the guide rope 15 moves to the right, thereby driving the guide block 17 to move to the left along the guide rail 16 (the moving direction of the guide block 17 is changed through the left fixed pulley 14), and the smoke screen 4 is slowly unfolded. The transmission structure is simple and efficient.

[0044] Further, in order to facilitate flexible use, the smoke and dust prevention device further comprises a pull rope 10, the pull rope 10 is arranged below the guide block 17 and is connected with the guide block 17, so as to facilitate the user to pull and reset the smoke screen 4.

[0045] The function principle of the utility model can be described by the following operation mode:

[0046] The two first vertical columns 1 are fixed in the preset position through screws, then the second vertical column 3 is vertically inserted into the first vertical column 1, and the fastening bolt 6 is screwed in the corresponding screw hole and screw groove 5, so as to fix the second vertical column 3. When it is needed to unfold the smoke screen 4 to close the space above the enclosure 2 to realize the smoke and dust prevention function, the user pulls the guide rope 15, so that the guide rope 15 moves to the right, drives the guide block 17 to slide to the left on the guide rail 16, and synchronously drives the smoke screen 4 to move to the left and unfold, until the smoke screen 4 contacts with the other second vertical column 3, then the guide rope 15 is wound and tied on the winding rod 19, thereby effectively preventing the smoke and dust from entering the passenger interface due to the displacement of the smoke screen 4, further ensuring the smoke and dust prevention effect, thereby reducing the response of the smoke sensor, and avoiding triggering the automatic fire alarm system.

[0047] When the smoke and dust prevention is not needed, the user pulls the pull rope 10 to the right, so that the pulling force can form a rightward component force, thereby driving the guide block 17 connected with the pull rope 10 to slide to the right on the guide rail 16, and further driving the smoke screen 4 to move to the right, and continuously recycling until the smoke screen 4 is reset to the original position.

[0048] It should be noted that: in the process of unfolding the smoke curtain 4, if the pipeline position affects, the closed fireproof cloth 8 can be disconnected, bypass the pipeline, and then use the fireproof adhesive 7 to bond the fireproof cloth 8, so that the smoke leakage phenomenon caused by the pipeline position can be effectively avoided.

[0049] In the embodiment of the present application, the smoke and dust prevention device for existing line station reconstruction provided by the present application comprises a first stand, a second stand, a fixing structure, a smoke curtain, a fireproof cloth, a guide structure and a fixing part. The first stand is fixed on the bottom surface through screws, so as to facilitate the user to adjust the distance between the first stands according to the actual construction span. The second stand is inserted on the first stand through the fixing structure, which not only facilitates the user to flexibly adjust the height of the second stand according to the actual smoke and dust blocking height requirement, ensures the effect of smoke and dust blocking, but also can fix the second stand by using the existing fence stand, thereby improving the integrity of the whole device. The smoke curtain and the fireproof cloth are arranged between the second stands, and the smoke curtain and the fireproof cloth are unfolded to block the originally open space above the existing fence, so as to effectively block the construction dust and other pollutants in the construction interface from entering the passenger operation interface, thereby preventing the smoke sensor from being triggered and false reported, greatly reducing the influence of construction on the existing line operation, and improving the safety of the construction process. The fixing part is arranged, so that when the user unfolds the smoke curtain, the guide rope can be fixed on the fixing part at any time according to the requirement, thereby further fixing the position of the unfolded and stayed smoke curtain, effectively preventing the smoke and dust from entering the passenger interface due to the displacement of the smoke curtain 4, further ensuring the smoke and dust prevention effect, and the whole device has simple structure, convenient use and flexibility.
