Description

Technical Field

[0001] This utility model relates to the field of smoke exhaust duct technology, specifically a fire smoke exhaust duct structure. Background Technology

[0002] Fire exhaust ducts are an important component of fire protection systems. They are mainly used to remove smoke and harmful gases from buildings during a fire to ensure the safety of personnel. Fire exhaust duct systems typically consist of supply and exhaust ducts, shafts, fire dampers, door switches, and fans.

[0003] Patent CN221197641U discloses a fire-fighting smoke exhaust duct structure for building engineering. In this application, a mounting base is used to fix a monitoring box to the ceiling. The interior of the monitoring box houses the equipment needed to detect smoke. Filter cotton purifies the smoke passing through it. A limiting groove provides a location for the installation of monitoring components. The combination of a fixing block and monitoring equipment allows the detection components to be placed inside the limiting groove. Lifting the monitoring equipment allows the fixing block to detach from the limiting groove, facilitating the replacement of the monitoring components. The monitoring probe extends the sensor to the center of the monitoring box, making data reading more accurate. Since this structure does not have components for detecting smoke filtration effectiveness, the purification status of smoke inside the duct can be understood in a timely manner, allowing personnel to evaluate the structure's smoke filtration effect.

[0004] The above-mentioned device has certain shortcomings in its use: when installing the exhaust duct, the device is mainly installed using a support plate and a pipe hanger, but there is no external restraint on the duct, which makes the exhaust duct not stable enough and poses a safety risk.

[0005] Therefore, this utility model provides a fire smoke exhaust duct structure to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a fire-fighting smoke exhaust duct structure that solves the aforementioned problems.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a fire smoke exhaust pipe structure, including pipe one and pipe two, pipe one and pipe two are arranged symmetrically on the left and right, and the adjacent sides of pipe one and pipe two are connected by the same sealing component, and fixing components are installed on the outer walls of pipe one and pipe two.

[0008] The fixing assembly includes two limiting frames arranged symmetrically vertically. Each limiting frame has a limiting groove on its adjacent side. The top and bottom of the outer wall of the second pipe have matching slots. Positioning blocks are fixedly installed at the front and rear ends of each limiting frame. The top wall of the top positioning block has an opening. The top wall of the positioning block on the lower limiting frame has a connecting frame fixedly installed. Each connecting frame has a limiting cavity inside. A tension spring is fixedly installed on the bottom wall of each limiting cavity. A sliding seat is fixedly installed on the top of each tension spring. A connecting seat is fixedly installed on the adjacent side of each sliding seat. A through groove is opened on the adjacent side of each connecting frame.

[0009] Through the above technical solution, the setting of the fixing component can limit and fix pipe two and pipe one by adjusting the position of the upper limiting frame, so that they have a good stable posture and prevent shaking during smoke exhaust.

[0010] Furthermore, the inner walls of both slots are engaged with the corresponding limiting slots for limiting, a handle is fixedly installed on the top wall of the upper limiting frame, the inner walls of both openings are slidably connected to the outer walls of the corresponding connecting frame, and the outer walls of both sliding seats are slidably connected to the inner walls of the corresponding limiting cavities.

[0011] Through the above technical solution, the card slot engages with the corresponding limiting slot to limit the movement, which can comprehensively limit the movement of pipe one and pipe two and improve stability. The limiting frame can be operated by the handle.

[0012] Furthermore, the outer walls of both connecting seats are slidably connected to the inner walls of the corresponding through slots, and the adjacent sides of the two connecting seats are fixedly connected to the inner walls of the corresponding through openings. Mounting seats are fixedly installed on the top walls of both connecting frames.

[0013] With the above technical solution, the connecting seat can slide along the inner wall of the corresponding through groove, and the mounting seat can be installed on the predetermined position of the smoke exhaust pipe by means of expansion bolts.

[0014] Furthermore, the sealing assembly includes two positioning frames, which are arranged symmetrically on the left and right sides. The inner walls of the two positioning frames are fixedly connected to the outer walls of the corresponding pipes one and two, and the side walls of the two positioning frames are in contact with each other.

[0015] The above technical solution improves the connection between pipe one and pipe two by ensuring that the positioning frames fit together.

[0016] Furthermore, several mounting openings are evenly provided on one side of the two positioning frames, and bolt and nut sets are fitted on the inner wall of each mounting opening.

[0017] Through the above technical solution, the positioning frame can be quickly fixed together with the installation port and bolt and nut assembly, thereby completing the installation connection of pipe one and pipe two.

[0018] Furthermore, a sealing groove is provided on the left side wall of pipe 2, and a sealing ring is fixedly installed on the right side wall of pipe 1, with the outer wall of the sealing ring fitting against the inner wall of the sealing groove.

[0019] Through the above technical solution, the cooperation between the sealing groove and the sealing ring can improve the connection sealing between pipe 2 and pipe 1, and prevent smoke leakage.

[0020] Furthermore, the adjacent sides of pipe one and pipe two are fitted together, and a connecting sealing pipe is fixedly installed on the right side of the inner wall of pipe one, with the right side of the outer wall of the connecting sealing pipe extending to the left side of the inner wall of pipe two.

[0021] Through the above technical solution, the connecting sealing pipe extends from pipe one into the interior of pipe two, providing a secondary sealing effect between the pipes.

[0022] Furthermore, rounded corners are provided on both the left and right sides of the connecting sealing tube.

[0023] With the above technical solution, the overall resistance of the connecting sealing pipe is reduced when the left and right sides of the connecting sealing pipe are rounded to allow smoke to escape.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1:

[0036] Please see Figures 1-5 A fire exhaust duct structure includes a first duct 1 and a second duct 2, which are arranged symmetrically on the left and right sides. The adjacent sides of the first duct 1 and the second duct 2 are connected by the same sealing component 3. The outer walls of the first duct 1 and the second duct 2 are both equipped with fixing components 4.

[0037] The fixing component 4 includes two limiting brackets 48, which are arranged symmetrically vertically. Each limiting bracket 48 has a limiting groove 49 on an adjacent side. Matching slots 41 are provided on the top and bottom of the outer wall of pipe 2. Positioning blocks 410 are fixedly installed at the front and rear ends of each limiting bracket 48. The top wall of the top positioning block 410 has an opening 411. Connecting brackets 42 are fixedly installed on the top wall of the positioning block 410 on the lower limiting bracket 48. Limiting cavities 43 are provided inside each connecting bracket 42. Tension springs 47 are fixedly installed on the bottom wall of each limiting cavity 43. Sliding seats 45 are fixedly installed at the top of each tension spring 47. Each of the two sliding seats 45 has a connecting seat 412 fixedly installed on one side of each adjacent side. Each of the two connecting frames 42 has a through groove 44 on one side of each adjacent side. The inner walls of the two slots 41 are engaged with the corresponding limiting grooves 49 for limiting. A handle 413 is fixedly installed on the top wall of the upper limiting frame 48. The inner walls of the two through openings 411 are slidably connected to the outer walls of the corresponding connecting frames 42. The outer walls of the two sliding seats 45 are slidably connected to the inner walls of the corresponding limiting cavities 43. The outer walls of the two connecting seats 412 are slidably connected to the inner walls of the corresponding through grooves 44. Each of the two connecting seats 412 has a fixedly connected side of each adjacent side to the inner wall of the corresponding through opening 411. An installation seat 46 is fixedly installed on the top wall of each of the two connecting frames 42.

[0038] In this embodiment of the utility model, the purpose of this setting is that the setting of the fixing component 4 can limit and fix the pipe 1 and pipe 2 in multiple directions when they are installed, so as to prevent the pipe 1 and pipe 2 from shaking during operation. Moreover, the installation method is relatively simple and can be adapted to different specifications of smoke exhaust pipes, and has a strong adaptability effect when used.

[0039] Example 2:

[0040] Please see Figures 1-5 This embodiment provides a technical solution based on embodiment one: the sealing component 3 includes two positioning frames 32, which are arranged symmetrically on the left and right. The inner walls of the two positioning frames 32 are fixedly connected to the outer walls of the corresponding pipe 1 and pipe 2. The side walls of the two positioning frames 32 are in contact with each other. Several installation ports 33 are evenly opened on the adjacent side of the two positioning frames 32. Bolt and nut groups are assembled on the inner walls of the several installation ports 33. A sealing groove 34 is opened on the left side wall of pipe 2. A sealing ring 31 is fixedly installed on the right side wall of pipe 1. The outer wall of the sealing ring 31 is in contact with the inner wall of the sealing groove 34. The adjacent side of pipe 1 and pipe 2 is in contact with each other. A connecting sealing pipe 35 is fixedly installed on the right side of the inner wall of pipe 1. The right side of the outer wall of the connecting sealing pipe 35 extends to the left side of the inner wall of pipe 2. Rounded corners are opened on both the left and right sides of the connecting sealing pipe 35.

[0041] In this embodiment of the utility model, the purpose of this arrangement is that the sealing component 3 can quickly connect pipe 1 and pipe 2 during installation, and after installation, it can abut and limit the connection. With the cooperation of the sealing ring 31 and the connecting sealing pipe 35, the sealing effect of pipe 1 and pipe 2 is achieved, preventing leakage of smoke and other issues.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] During operation, when installing pipe 1 and pipe 2, pipe 1 and pipe 2 are first connected and fixed using the sealing assembly 3. Moving pipe 1 causes the corresponding positioning bracket 32 ​​to approach the left side of pipe 2 and fit against the side wall of the positioning bracket 32. Pipe 1 then causes the sealing ring 31 to enter the inner wall of the sealing groove 34, and the connecting sealing pipe 35 to extend into the interior of pipe 2. Then, bolts and nuts are used to pass through the installation port 33 to install and connect the positioning bracket 32 ​​and pipes 1 and 2. Moving the entire fixing assembly 4 and using expansion bolts, the mounting base 46 is installed at the required fixed position on the fire exhaust pipe. Next, pulling the handle 413 upwards moves the upper limit bracket 48 and the positioning block 410, causing the opening 411 to slide upwards along the outer wall of the corresponding connecting bracket 42. When the limiting bracket 48 is in motion, it will drive the connecting seat 412 to slide upward along the inner wall of the through groove 44. Simultaneously, the connecting seat 412 will drive the sliding seat 45 to slide upward in the inner wall of the corresponding limiting cavity 43 and stretch the tension spring 47, placing pipe 1 and pipe 2 on the position of the lower limiting bracket 48, so that the locking groove 41 and the inner wall of the lower limiting groove 49 are locked and limited. When the handle 413 is released, under the elastic action of the tension spring 47, it will pull the sliding seat 45 to slide in the inner wall of the limiting cavity 43, and the connecting seat 412 will slide downward in the inner wall of the corresponding through groove 44, so that the upper limiting bracket 48 will drive the corresponding limiting groove 49 into the inner wall of the locking groove 41 at the top to lock and limit, thereby completing the installation and fixing of pipe 1 and pipe 2, and limiting the outer periphery of pipe 1 and pipe 2 in multiple directions to prevent them from shifting or shaking.
