Description

Technical Field

[0001] The utility model relates to the technical field of baffle doors, in particular to an anti-penetration sealing mechanism for a smoke baffle door. Background Art

[0002] The baffle door, also known as the air regulating valve, is mainly composed of a frame, blades, sealing plates, a main shaft, bearings, shaft seals, a crank-connecting rod mechanism, etc. It is mainly used in the smoke and air ducts of power plants to intercept the medium. It has the function of full opening and full closing, allowing the medium to flow or shut off in the pipeline. Its frame is made of steel plate die-casting, steel section welding or casting, and the streamlined cross-section of the blades ensures that the medium pressure loss is extremely small.

[0003] After long-term and frequent opening and closing, the closing point of the baffle door may become loose, which will cause the closing point line to not fit tightly, thus easily creating a gap. The smoke may invade the interior along the gap of the baffle door, bringing potential risks and hazards to the normal operation and use of the equipment. The smoke may corrode the internal components of the equipment, causing equipment failure or damage, affecting the performance and efficiency of the equipment, and reducing the service life of the equipment. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the gap between the baffle door is prone to closing difference and affects the sealing performance after long-term use, and the utility model provides a smoke baffle door anti-penetration sealing mechanism.

[0007] Furthermore, the protective mechanism includes an anti-slip layer and a central axis, the outer sides of the anti-slip layer and the central axis are fixedly connected to the inner side of the protective frame, the side walls of the prying mechanism are movably connected to the side walls of the anti-slip layer, the side ends of the sealing mechanism are slidably connected to the inner side of the central axis, and the anti-slip layer is arranged in the middle of the side walls of the central axis.

[0008] Furthermore, the prying mechanism includes a connecting strip, a support plate, an elastic plate, a rocker plate, a movable rod and a prying hook. The side walls of the connecting strip and the support plate are fixedly installed on the side walls of the protective mechanism. The inner side of the elastic plate is movably connected to the middle part of the side wall of the protective mechanism. The side wall of the rocker plate is slidably connected to the side wall of the protective mechanism. The side ends of the movable rod and the prying hook are slidably connected to the side wall of the protective mechanism. After the side ends of the sealing mechanism are closed, they will be squeezed toward the middle along the side walls of the elastic plate. The side walls of the elastic plate are aligned with the same plane of the connecting strip and press the movable rod inward.

[0009] Furthermore, the inner end of the support plate is fixedly connected to the two side ends of the connecting strip, the elastic plate and the side wall of the connecting strip are installed together at intervals, and the inner end of the rocker plate passes through and is fixedly connected to the inner end side wall of the elastic plate.

[0010] Furthermore, one end of the movable rod is fixedly connected to the inner center of the elastic plate, the end of the movable rod away from the center of the elastic plate is movably connected to the inner end of the prying hook, and the outer end of the prying hook is movably connected to the inner side wall of the rocker. The side wall of the prying hook is tilted toward the rocker, which can push the side wall of the rocker to fit between the two end side walls of the sealing mechanism.

[0011] Furthermore, the sealing mechanism includes a door panel body, an L-shaped edge, a cylindrical bar, a push bar, a long cover plate and a channel hole. The outer side of the rotating rod is connected to the inner axis of the door panel body, and the side walls of the L-shaped edge at the upper and lower ends are connected to each other in opposite directions. The outer side of the cylindrical bar is movably connected to the top end of the L-shaped edge. When the side walls of the sealing mechanism rotate and the upper and lower ends are closed, the side walls of the door panel body located at the L-shaped edge are buckled together.

[0012] Furthermore, the channel hole is arranged at the upper end of the front side of the door panel body, the inner end of the push strip is fixedly connected to the bottom end of the L-shaped edge, the side wall of the push strip passes through the interior of the channel hole, the outer end of the push strip is fixedly connected to the bottom end of the long cover plate, the inner side of the channel hole is slidably connected to the connection of the door panel body, and the push strip pushes the long cover plate toward the outer upper end of the door panel body around the interior of the channel hole, so that the side wall of the long cover plate can be tightly covered between the gaps between the connection points of the door panel body.

[0013] Compared with the prior art, the present invention provides a smoke damper door anti-penetration sealing mechanism, which has the following beneficial effects:

[0014] The smoke damper door's anti-infiltration sealing mechanism activates the sidewalls of the prying mechanism when the sidewalls of the sealing mechanism close, protecting the vertical corners of the sealing mechanism. Simultaneously, the sealing mechanism itself seals the closing points when closed, providing additional protection against smoke infiltration. This design not only enhances the device's protective performance, effectively preventing smoke intrusion and ensuring personnel safety, but also reduces the need for manual intervention, improving the device's reliability and ease of use.
