Description

Technical Field

[0001] The utility model relates to the technical field of fire dampers, in particular to a highly corrosion-resistant fire damper. Background Technique

[0002] A fire damper is a form of valve that controls the temperature of a memory alloy and closes under the action of gravity and a spring mechanism. In new products, there are also those that use the deformation of a memory alloy to close the valve. Its function is: when the flue gas temperature reaches 280 °C, people have basically been evacuated, and smoke exhaust is no longer practically meaningful. At this time, the flue gas already contains fire, and the valve automatically closes to prevent the spread of fire.

[0003] Existing smoke exhaust ducts are usually located at high places. When installing a fire damper, workers need to hold the fire damper on the smoke exhaust duct all the time. Workers holding heavy objects at high places for a long time are prone to fatigue, which may lead to accidental drops, causing personal injuries or equipment damage. The manual holding and installation process takes a long time, affecting the overall construction progress. It requires multiple people to cooperate, increasing labor costs and coordination difficulties. Therefore, a fire damper that does not require holding during installation is needed to improve the safety and efficiency of installation. Summary of the Utility Model

[0027] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] Secondly, the present utility model will be described in detail in conjunction with the schematic diagrams. When detailing the embodiments of the present utility model, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0029] To make the objectives, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0030] Please refer to Figures 1 - 4 As shown, this embodiment is a highly corrosion-resistant fire damper, including:

[0031] A fire damper assembly, which includes a fire damper housing 11. The fire damper assembly further includes an actuator 12, a temperature sensor 13, and blades 14. The actuator 12 is fixed at the center of one side of the outer surface of the fire damper housing 11. The temperature sensor 13 is fixed inside the fire damper housing 11. The blades 14 are rotatably installed inside the fire damper housing 11.

[0032] The fire damper housing 11 is the external structure of the entire fire damper assembly, which is used to protect the internal components and ensure their normal operation. The actuator 12 is the control center of the fire damper, responsible for receiving signals from the temperature sensor 13 and driving the rotation of the blades 14. When the temperature reaches the set value, the actuator 12 will start, causing the blades 14 to close and preventing the spread of fire. The temperature sensor 13 is used to monitor the ambient temperature. When the temperature exceeds the preset value, the temperature sensor 13 sends a signal to the actuator 12 to trigger the action of the fire damper.

[0033] A fixing assembly, which includes a fixing block 21, a first limiting rod 22, a first fixing plate 23, a first threaded rod 24, a bearing 25, and a first clamping plate 26. The fixing block 21 is fixed at the centers of the upper and lower surfaces of the fire damper housing 11. The first limiting rod 22 is fixed on both sides of the upper surface of the fixing block 21. The first fixing plate 23 is fixed on the upper surface of the first limiting rod 22. The first threaded rod 24 threadedly penetrates the center of the outer surface of the first fixing plate 23. The bearing 25 is rotatably installed on the lower outer surface of the first threaded rod 24. The first clamping plate 26 is fixed on the lower surface of the bearing 25, and the first clamping plate 26 penetrates the first limiting rod 22.

[0034] The fixed block 21 provides a basic installation platform to ensure that the fire damper does not shake or shift during operation. The first limiting rod 22 and the second limiting rod 27 are used to limit the moving range of the first clamping plate 26 and the second clamping plate 291, ensuring that they can be accurately fixed on the upper and lower surfaces of the smoke exhaust pipe. The first threaded rod 24 and the second threaded rod 29 are rotated to adjust the positions of the first clamping plate 26 and the second clamping plate 291. When rotated counterclockwise, the first threaded rod 24 moves downward, and the second threaded rod 29 moves upward, causing the first clamping plate 26 and the second clamping plate 291 to clamp towards the middle synchronously and contact the surface of the smoke exhaust pipe. When rotated clockwise, the first threaded rod 24 moves upward, and the second threaded rod 29 moves downward, causing the first clamping plate 26 and the second clamping plate 291 to move upward and downward synchronously to open the clamp.

[0035] The fixing assembly further includes a second limiting rod 27, a second fixing plate 28, a second threaded rod 29 and a second clamping plate 291. The second limiting rod 27 is fixed on both sides of the lower surface of the lower fixed block 21. The second fixing plate 28 is fixed on the lower surface of the second limiting rod 27. The second threaded rod 29 is threadedly penetrated through the center of the outer surface of the second fixing plate 28. The second clamping plate 291 is fixed on the upper surface of the second threaded rod 29. The upper outer surface of the upper end of the second threaded rod 29 is rotatably penetrated through a bearing 25, and the upper surface of the bearing 25 is fixed on the lower surface of the second clamping plate 291, and the first clamping plate 26 and the second clamping plate 291 are in contact with the two upper surfaces of the smoke exhaust pipe.

[0036] The bearing 25 is used to reduce the frictional resistance when the threaded rod rotates, making the operation smoother. At the same time, it also helps to maintain the stability and accuracy of the threaded rod. The first fixing plate 23 and the second fixing plate 28 provide a platform for the installation and rotation of the threaded rod, ensuring the stability and accuracy of the threaded rod.

[0037] Working principle:

[0038] When installing the fire damper, to avoid the staff from lifting the fire damper, the fire damper can be directly aligned with the smoke exhaust pipe. Immediately afterwards, rotate the first threaded rod 24. The first threaded rod 24 rotates counterclockwise on the surface of the first fixing plate 23, causing the first threaded rod 24 to move downward within the first fixing plate 23. Synchronously connected by the bearing 25, the first clamping plate 26 moves downward on the outer surface of the first limiting rod 22 until the first clamping plate 26 contacts the upper surface of the smoke exhaust pipe. Then rotate the second threaded rod 29 counterclockwise to move upward within the second fixing plate 28, causing the second clamping plate 291 to move upward. The second clamping plate 291 contacts the lower surface of the smoke exhaust pipe. In this way, the first clamping plate 26 and the second clamping plate 291 fix and clamp the upper and lower surfaces of the smoke exhaust pipe. At this time, the staff does not need to lift the fire damper.

[0039] In this step, by rotating the first threaded rod 24 and the second threaded rod 29 to fix the fire damper, it can effectively prevent the staff from holding heavy objects for a long time, and improve the installation efficiency and safety.

[0040] Please refer to Figure 4 As shown, on the basis of the above-mentioned Embodiment 1, this embodiment further includes:

[0041] A limit component, which includes a side connection frame 31, a spring 32 and a limit plate 33. The side connection frame 31 is L-shaped, and the side connection frame 31 is fixed to the middle of one side of the outer surface of the fire damper housing 11. The springs 32 are equidistantly fixed on one side of the side connection frame 31, and the limit plate 33 is fixed on one side of the spring 32. There are two groups of limit components, which are respectively fixed at the centers of both sides of the fire damper housing 11, and the limit plate 33 abuts against both sides of the outer surface of the exhaust pipe;

[0042] The side connection frame 31 is L-shaped and fixed to the middle of one side of the outer surface of the fire damper housing 11, providing an installation platform and support for the spring 32 and the limit plate 33. The springs 32 are equidistantly fixed on one side of the side connection frame 31, providing elastic force for the limit plate 33, which helps to stably place the fire damper housing 11 in the middle position of the exhaust pipe.

[0043] Working principle:

[0044] When installing the fire damper, the two side connection frames 31 are located on both sides of the exhaust pipe. Under the elastic force of the two springs 32, the two limit plates 33 place the fire damper housing 11 in the middle of the exhaust pipe. Through the combined use of the side connection frame 31 and the limit plate 33, precise positioning and support are provided for the fire damper housing 11;

[0045] This step ensures that the fire damper can be accurately installed in the predetermined position, and the installation of the fire damper can be quickly completed without complex adjustment and fixing steps.
