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] Embodiment 1: A first mounting groove 7 is installed at the top of the first smoke and air duct 1 and the second smoke and air duct 5, a first sprocket 4 and a second sprocket 10 are installed on both sides of the first mounting groove 7, a transmission belt 6 is installed between the first sprocket 4 and the second sprocket 10, a second mounting groove 11 is installed on one side of the first smoke and air duct 1 and the second smoke and air duct 5, a transmission shaft 3 is installed inside the second mounting groove 11, three first gears 12 are installed at equal distances on the outside of the transmission shaft 3, three partition plates 15 are movably installed inside the first smoke and air duct 1 and the second smoke and air duct 5, respectively. Three second gears 13 are installed at equal distances on one side of the interior of the transmission shaft 3, the bottom ends of the first sprocket 4 and the second sprocket 10 extend into the interior of the two second mounting grooves 11 respectively, the bottom ends of the first sprocket 4 and the second sprocket 10 are connected to the top ends of the two transmission shafts 3 respectively, the top end of the first mounting groove 7 is installed with a motor 9, one end of the second gear 13 is connected to one side of the partition plate 15, and the first gear 12 and the second gear 13 are connected by tooth meshing, the output end of the motor 9 extends into the interior of the first mounting groove 7, and the output end of the motor 9 is connected to the top end of the second sprocket 10.
[0022] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the rotation of the output end of the motor 9 can drive the second sprocket 10 to rotate. When the second sprocket 10 rotates, the transmission of the transmission belt 6 can simultaneously drive the first sprocket 4 to rotate. The rotation of the first sprocket 4 and the second sprocket 10 can simultaneously drive the transmission shaft 3 installed inside the first smoke and air duct 1 and the second smoke and air duct 5 to rotate. When the transmission shaft 3 rotates, it will drive the first gear 12 to rotate. Since the first gear 12 and the second gear 13 are connected by tooth meshing, the rotation of the first gear 12 can drive the second gear 13 to rotate. When the second gear 13 rotates, the first smoke and air duct 1 and the second smoke and air duct 5 The three partition plates 15 installed inside rotate to adjust the wind speed and air volume inside the first smoke and air duct 1 and the second smoke and air duct 5. When a fire occurs inside the first smoke and air duct 1 and the second smoke and air duct 5, the rotation of the output end of the motor 9 can drive the partition plates 15 installed inside the first smoke and air duct 1 and the second smoke and air duct 5 to rotate, so that the multiple partition plates 15 installed inside the first smoke and air duct 1 and the second smoke and air duct 5 are spliced together, thereby isolating the interior of the first smoke and air duct 1 and the second smoke and air duct 5 to prevent the fire from spreading, thereby protecting the equipment connected at one end of the first smoke and air duct 1 and the second smoke and air duct 5 to prevent the fire from damaging the equipment.
[0023] Embodiment 2: A first connecting plate 18 is respectively installed on both sides of the first smoke and air duct 1, and a second connecting plate 19 is respectively installed on both sides of the second smoke and air duct 5. The first connecting plate 18 and the second connecting plate 19 are connected by a plurality of hexagonal bolts 2. Three limiting holes 16 are respectively opened at equal distances on one side inside the first smoke and air duct 1 and the second smoke and air duct 5, and a movable column 17 is respectively installed on one side of the plurality of partition plates 15. The movable column 17 extends into the interior of the limiting hole 16, and the movable column 17 is movably installed inside the limiting hole 16. The areas of the plurality of partition plates 15 are equal, and insulation plates 14 are respectively installed inside the first smoke and air duct 1 and the second smoke and air duct 5.
[0024] Specifically, Figure 1 and Figure 2 As shown, since a movable column 17 is installed on one side of the partition plate 15, and the movable column 17 is extended and slidably installed inside the limiting hole 16, when the partition plate 15 rotates, the movable column 17 will rotate inside the limiting hole 16, thereby ensuring the normal rotation of the partition plate 15. Since the first smoke and air duct 1 and the second smoke and air duct 5 are respectively installed with insulation plates 14, the internal temperatures of the first smoke and air duct 1 and the second smoke and air duct 5 can be kept warm by the insulation plates 14 to reduce heat loss.
[0025] Working principle: When in use, install the first smoke and air duct 1 and the second smoke and air duct 5, and then connect the first smoke and air duct 1 and the second smoke and air duct 5 to the equipment. When a fire occurs inside the first smoke and air duct 1 and the second smoke and air duct 5, the rotation of the output end of the motor 9 can drive the second sprocket 10 to rotate. When the second sprocket 10 rotates, the transmission belt 6 can simultaneously drive the first sprocket 4 to rotate. The rotation of the first sprocket 4 and the second sprocket 10 can simultaneously drive the transmission shaft 3 installed inside the first smoke and air duct 1 and the second smoke and air duct 5 to rotate. When the transmission shaft 3 rotates, it will drive the first gear 12 to rotate. Since the first gear 12 is connected to the second gear 13 by tooth meshing, the rotation of the first gear 12 can drive the second gear 13 to rotate. When the second gear 13 rotates, the three partition plates 15 installed inside the first smoke and air duct 1 and the second smoke and air duct 5 will rotate, so that the multiple partition plates 15 installed inside the first smoke and air duct 1 and the second smoke and air duct 5 are spliced together, thereby isolating the interior of the first smoke and air duct 1 and the second smoke and air duct 5 to prevent the fire from spreading, thereby protecting the equipment connected at one end of the first smoke and air duct 1 and the second smoke and air duct 5 to prevent the fire from damaging the equipment.
[0026] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
