Description
Technical Field
[0001] The utility model relates to the technical field of smoke exhaust fire dampers, in particular to a mounting assembly and a smoke exhaust fire damper. Background Art
[0002] The smoke exhaust fire damper is a fire-fighting component, which is generally installed on the pipes of the mechanical smoke exhaust system. It is usually in the open state and opens to exhaust smoke when a fire occurs. It closes when the smoke temperature in the smoke exhaust pipe reaches 280 degrees and meets the smoke leakage and fire resistance integrity requirements within a certain period of time, playing the role of isolating smoke and preventing fire. Its installation parts serve as the connecting parts between the smoke exhaust fire damper and the pipe, and play the function of connection protection to ensure that the smoke exhaust fire damper can be used effectively.
[0003] The smoke exhaust fire dampers on the market are usually open. In the event of a fire, they automatically close when the smoke temperature in the smoke exhaust duct reaches 280 degrees. Due to the long-term use of smoke exhaust fire dampers and the fire that may be accompanied by power outages, the smoke exhaust fire dampers may not be able to close normally, causing the fire to spread, increasing the difficulty of firefighting, and causing trouble for firefighters. To this end, we propose an installation component and a smoke exhaust fire damper. Utility Model Content
[0004] The purpose of the present utility model is to provide a mounting assembly and a smoke exhaust fire damper to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an installation assembly, comprising a main body, an upper smoke exhaust pipe and an isolation plate, the upper end of the main body is connected to the upper smoke exhaust pipe, and the angle between the upper smoke exhaust pipe and the main body is 30-60°, the main body is connected to a fire extinguishing pipe at a horizontal position on one side close to the upper smoke exhaust pipe, and a bottom support is welded to the middle part of the inner wall of the main body, the ends of the main body, the upper smoke exhaust pipe and the fire extinguishing pipe are welded with a mounting baffle, and a plurality of screw holes are provided on the surface of the mounting baffle, a base is welded to the bottom of the lower end of the fire extinguishing pipe, and the base is mounted on a fire-fighting pipe, an isolation plate is mounted at the connection between the upper smoke exhaust pipe and the fire extinguishing pipe, and a smoke exhaust fire damper is fastened with bolts at one end of the main body away from the upper smoke exhaust pipe and the fire extinguishing pipe.
[0006] Preferably, the bottom support is distributed in an inclined manner, and the inclination angle of the bottom support is 30-60°.
[0007] Preferably, a fixed shaft is fixed to one end of the isolation plate, and shaft frames are mounted on both ends of the fixed shaft, and bearings are sleeved at the connection between the shaft frames and the fixed shaft.
[0008] Preferably, the outer ring of the bearing is sleeved on the inner wall of the shaft frame, and the inner ring of the bearing is sleeved on the outer wall of the fixed shaft.
[0009] Preferably, a mounting plate is fixed to the outer wall of the shaft frame, and the mounting plate is bolted to the surface of the upper smoke exhaust pipe and the fire extinguishing pipe respectively.
[0010] Preferably, an adjustment handle for manual grip is sleeved on the outer wall of one end of the fixed shaft, and the isolation plate forms an adjustment structure through the bearing and the adjustment handle.
[0011] Preferably, the isolation plate separates the main body, the upper smoke exhaust pipe and the fire extinguishing pipe into two isolation spaces, and the main body and the upper smoke exhaust pipe form one isolation space, and the main body and the fire extinguishing pipe form one isolation space.
[0012] Preferably, the insulation board is placed on the bottom support platform, and the bottom of the insulation board under the bottom support platform is sealed and protected.
[0013] Compared with the prior art, the beneficial effects of the present invention are: when the installation assembly and the smoke exhaust fire damper are in use, the bottom support serves as a sealing and protective component at the bottom of the main body, and the main body and the upper smoke exhaust pipe form an isolation space, reducing the internal distribution of smoke or air along the main body and the fire extinguishing pipe to form an isolation space, improving the sealing strength between the isolation plate and the main body, satisfying the user's need to switch between different isolation spaces, and facilitating user use.
[0014] The main body and the fire extinguishing pipe form an isolated space, which can be designed to be closed. When all personnel in the fire scene are evacuated, the smoke supply to one end of the smoke exhaust fire damper can be cut off through the closed space, making it convenient for subsequent firefighters to extinguish the fire source and reduce the occurrence of fire overflow. The main body and the upper smoke exhaust pipe serve as ventilation ducts, which meet the requirements of the ventilation ducts for conveying internal smoke in a fire and provide protection for the evacuation of internal personnel.
[0015] This adjustment structure serves as a double protection structure and cooperates with the smoke exhaust fire damper. When the smoke exhaust fire damper cannot close automatically normally, the smoke delivery end is closed by adjusting the structure to meet the smoke leakage and fire resistance integrity requirements within a certain period of time, thereby playing a role in isolating smoke and preventing fire. This structure is manually operated, and its fixed axis is distributed along the outside of the pipe. The user can switch it by manually moving it from the outside to ensure that the double protection structure can be effectively used, so as to prevent the first protection structure of the smoke exhaust fire damper from being able to be used normally, and to isolate smoke and prevent fire as much as possible, providing firefighters with an effective operating environment and convenience for users.
