[0002] Air conditioning equipment refers to equipment that supplies treated air to a designated space to maintain a specified temperature and humidity, and control the content of dust and harmful gases. The use of air conditioning equipment involves the use of smoke exhaust fire dampers, which are fire-fighting components installed on the ducts of mechanical smoke exhaust systems. Their design meets certain requirements for smoke leakage and fire resistance integrity, ensuring that they can effectively prevent the spread of smoke and flames in the event of a fire.

[0003] However, current smoke exhaust fire dampers still have some shortcomings. For example, a filter-type smoke exhaust fire damper with application number 202322612443.3 has not fully considered the installation structure of the smoke exhaust fire damper. When using smoke exhaust fire dampers in air conditioning equipment, if the installation structure of the smoke exhaust fire damper is not fully considered, the staff may spend a lot of time during installation, and the connection between the smoke exhaust fire damper and the external pipeline may not be tight enough, resulting in leakage at the subsequent connection, which makes it inconvenient for the staff to use the smoke exhaust fire damper.

[0004] Therefore, there is an urgent need to improve this shortcoming. This utility model studies and improves the existing structure and its deficiencies, and provides a smoke exhaust fire damper that is easy to install. Utility Model Content

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 and Figure 2 As shown, an easy-to-install smoke exhaust fire damper includes a fixed pipe 1, a filter assembly 5, and an external pipe 6. A controller 2 is installed above the fixed pipe 1, and a rotating rod 3 is rotatably connected inside the fixed pipe 1. A baffle plate 4 is fixedly connected to the outside of the rotating rod 3. The filter assembly 5 is located on one side inside the fixed pipe 1 and includes a drive motor 501, a limit screw 502, a scraper 503, a limit rod 504, a filter plate 505, and a connecting block 506. The drive motor 501 is located outside the fixed pipe 1, and the output shaft of the drive motor 501... A limiting screw 502 is fixedly connected by a coupling, and the limiting screw 502 is rotatably connected inside the fixed pipe 1. A scraper 503 is rotatably connected to the outside of the limiting screw 502, and a limiting rod 504 is connected through one side of the scraper 503. The end of the limiting rod 504 is welded to the inner wall of the fixed pipe 1. A filter plate 505 is in close contact with the side of the scraper 503, and the filter plate 505 is in contact with the inner wall of the fixed pipe 1. Connecting blocks 506 are welded to the four corners of the filter plate 505, and the connecting blocks 506 are fixedly connected to the fixed pipe 1 by bolts.

[0023] The specific operation is as follows: When gas passes through the fixed pipe 1, the filter plate 505 in the filter assembly 5 performs a certain filtration treatment on the gas. The drive motor 501 drives the limit screw 502 to rotate, causing the scraper 503 connected to the outside of the limit screw 502 to move. Under the restriction of the limit rod 504, the scraper 503 moves up and down, thereby causing the scraper 503 to scrape the surface of the filter plate 505 to ensure the permeability of the filter plate 505. When the temperature inside the fixed pipe 1 reaches the limit, the controller 2 causes the rotating rod 3 to rotate, thereby causing the blocking plate 4 fixedly connected to the outside of the rotating rod 3 to rotate. The blocking plate 4 is used to block the gas inside the fixed pipe 1. The structure is simple and convenient for workers to use the smoke exhaust fire damper.

[0024] like Figure 1 and Figure 3 As shown, the external pipe 6 is arranged on both sides of the fixed pipe 1, and flange plates 7 are welded to the ends of both the fixed pipe 1 and the external pipe 6. A connecting assembly 8 is arranged on the outer side of the flange plate 7. The connecting assembly 8 includes a rotating part 801, a connecting rod 802, a connecting plate 803, a limiting part 804, and an arc-shaped block 805. One end of the rotating part 801 is fixedly connected to the connecting rod 802, and the rotating part 801 is rotatably connected to the flange plate 7 through the connecting rod 802. The outer wall of the end of the connecting rod 802 is threaded, and the connecting rod 802 is connected to the flange plate 7 through the thread. Rotary connection with nut, a connecting plate 803 is provided on one side of the rotating part 801 for internal limiting, and a limiting part 804 is welded on one side of the connecting plate 803. The inner side of the limiting part 804 contacts the flange plate 7. Bolts are provided on one side of the ends of the rotating part 801 and the limiting part 804. The rotating part 801 and the limiting part 804 are fixedly connected to the flange plate 7 by bolts. Arc-shaped blocks 805 are welded on the outer surfaces of the rotating part 801 and the limiting part 804. A bolt is provided at the center of the arc-shaped block 805. The arc-shaped blocks 805 are fixedly connected to each other by bolts.

[0025] The specific operation is as follows: The operator inserts the connecting rod 802, which is fixedly connected to one end of the rotating part 801 at the four corners of the flange plate 7, through it. Using the thread on the outer wall of the end of the connecting rod 802, the nut is rotated to connect with the connecting rod 802, thereby fixing the flange plate 7 relatively. Then, the connecting rod 802 is used to rotate the rotating part 801 and adjust the position of the connecting plate 803 inside the rotating part 801 so that the limiting part 804 welded on one side of the connecting plate 803 also contacts the flange plate 7. Bolts are used to fix the arc-shaped block 805 welded to the outer surface of the rotating part 801 and the limiting part 804. Finally, bolts are used to fix the other side of the rotating part 801 and the limiting part 804, and the bolts penetrate the flange plate 7. Thus, the rotating part 801 and the limiting part 804 are fixedly connected to the flange plate 7 by bolts. The structure is simple, which makes it easy for operators to install and use the smoke exhaust fire damper.

[0026] In summary, this easy-to-install smoke exhaust fire damper, according to Figures 1-3 The structure shown, when used in the smoke exhaust fire damper of the air conditioning equipment, firstly, when gas passes through the fixed pipe 1, the filter plate 505 in the filter assembly 5 performs a certain filtration treatment on the gas. The drive motor 501 drives the limit screw 502 to rotate, causing the scraper 503 rotatably connected to the outside of the limit screw 502 to move. Under the restriction of the limit rod 504, the scraper 503 moves up and down, thus scraping the surface of the filter plate 505 to ensure the permeability of the filter plate 505. When the temperature inside the fixed pipe 1 reaches its limit, the controller 2 causes the rotating rod 3 to rotate, thereby causing the blocking plate 4 fixedly connected to the outside of the rotating rod 3 to rotate. The blocking plate 4 blocks the gas inside the fixed pipe 1. In addition, the operator moves the four corners of the flange plate 7... A connecting rod 802, which is fixedly connected to one end of the rotating component 801, passes through the flange plate 7. A nut is rotatably connected to the connecting rod 802 using threads on the outer wall of the connecting rod 802, thus fixing the flange plate 7 relative to each other. The rotating component 801 is then rotated using the connecting rod 802, adjusting the position of the connecting plate 803 within the rotating component 801. This ensures that the limiting component 804 welded to one side of the connecting plate 803 also contacts the flange plate 7. Bolts are then used to fix the arc-shaped block 805 welded to the outer surface of the rotating component 801 and the limiting component 804. Finally, bolts are used to fix the other side of the rotating component 801 and the limiting component 804, with the bolts passing through the flange plate 7. Therefore, the rotating component 801 and the limiting component 804 are fixedly connected to the flange plate 7 via bolts. This simple structure facilitates the use of the smoke exhaust fire damper by personnel.
