DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application; obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments of the application; based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0031] As shown in Figures 1-5 , the embodiment of the application discloses a plate type smoke exhaust port for building fire-fighting smoke exhaust system, which comprises a valve frame 1, a rotating rod 2, a sealing plate 21, a limiting assembly 4, a silica gel block 6 and a magnet block 8. A rotating groove 11 is formed in the inner wall of the valve frame 1, the rotating rod 2 is in a circular rod structure, and the rotating rod 2 is rotationally arranged in the rotating groove 11. The sealing plate 21 is in a plate structure, and the sealing plate 21 is fixed on the rotating rod 2.

[0032] The valve frame 1 is provided with a communication groove 3 on each of the opposite side walls, and a sliding groove 31 is formed on the inner wall of the valve frame 1. A limiting assembly 4 is arranged on the valve frame 1 and used for limiting the sealing plate 21. The limiting assembly 4 comprises a first sliding block 41, a second sliding block 42, a first blocking rod 43, a second blocking rod 44 and a fixing device 5. The first sliding block 41 is in the shape of a rectangular block, and the second sliding block 42 is in the shape of a rectangular block. The first sliding block 41 and the second sliding block 42 are respectively arranged in the two sliding grooves 31. The first blocking rod 43 is in the shape of a rectangular rod, and the first blocking rod 43 is fixed on the side wall of the first sliding block 41. The second blocking rod 44 is in the shape of a rectangular rod, and the second blocking rod 44 is fixed on the side wall of the second sliding block 42.

[0033] When the staff needs to rotate the sealing plate 21, the staff needs to close the fixing device 5 and slide the first sliding block 41 and the second sliding block 42 away from each other, so that the first blocking rod 43 and the second blocking rod 44 move away from each other, thereby separating the first blocking rod 43 and the second blocking rod 44 from the sealing plate 21. Further, when the staff only needs to push the bottom of the sealing plate 21, the sealing plate 21 can be rotated, so that the flue gas is discharged through the valve frame 1.

[0034] The silica gel block 6 is arranged on the side wall of the first blocking rod 43 and the second blocking rod 44, and the side wall of the two silica gel blocks 6 is provided with an arc-shaped groove 61. When the staff makes the first blocking rod 43 abut against the sealing plate 21, the silica gel block 6 abuts against the sealing plate 21, thereby reducing the probability of leaving a gap between the sealing plate 21 and the silica gel block 6, and further improving the sealing effect of the sealing plate 21.

[0035] The fixing device 5 is arranged on the valve frame 1 and used for blocking the first blocking rod 43 and the second blocking rod 44. The fixing device 5 comprises a first fixing rod 51 and a second fixing rod 52. The first fixing rod 51 is in the shape of a rod and is rotatably arranged on the side wall of the valve frame 1. The second fixing rod 52 is in the shape of a rod and is rotatably arranged on the side wall of the valve frame 1 away from the first fixing rod 51. The first fixing rod 51 and the second fixing rod 52 have the same size, and the side wall of the first blocking rod 43 and the second blocking rod 44 away from each other is provided with a containing groove 7 for containing the first fixing rod 51.

[0036] When the first blocking rod 43 abuts against the sealing plate 21, the staff needs to fix the first blocking rod 43. At this time, the staff needs to continuously push the first blocking rod 43 and rotate the first fixing rod 51 downward, so that the first fixing rod 51 gradually faces the containing groove 7. Then, the staff needs to release the first blocking rod 43, so that the silica gel block 6 rebounds, thereby connecting the first fixing rod 51 and the containing groove 7, and further limiting the first blocking rod 43 by the first fixing rod 51.

[0037] The magnet block 8 is in a block structure, and is embedded on the side wall of the sealing plate 21, and is used for improving the stability of the sealing plate 21. Since the valve frame 1 is made of metal material, when the sealing plate 21 is not subjected to external force, the magnet block 8 is always adsorbed with the valve frame 1, thereby improving the stability of the sealing plate 21, and further reducing the difficulty of the staff to make the first stop lever 43 abut against the sealing plate 21.

[0038] In order to reduce the difficulty of the staff to rotate the first fixed rod 51, thereby improving the use experience of the staff, the thickness of the first fixed rod 51 is greater than 1.5 cm.

[0039] The use principle of the plate type smoke exhaust port for a building fire-fighting smoke exhaust system in the embodiment is as follows: when the staff needs to exhaust smoke, the staff needs to rotate the sealing plate 21. At this time, the staff only needs to close the fixing device 5, and slide the first stop lever 43 and the second stop lever 44 to the direction away from each other, so as to make the first stop lever 43 and the second stop lever 44 separate from the sealing plate 21. Further, the staff only needs to push the sealing plate 21 from the bottom of the valve frame 1, so as to make the sealing plate 21 rotate with the rotating rod 2, thereby opening the valve frame 1, and further making the smoke exhaust through the valve frame 1, thereby reducing the difficulty of the staff to rotate the sealing plate 21.
