Description

Technical Field

[0001] The utility model relates to the technical field of fire smoke exhaust pipes, in particular to a smoke exhaust pipe used for fire fighting. Background Art

[0002] Firefighting is a general term for eliminating hidden dangers and preventing disasters. The purpose of firefighting is to reduce the degree of damage caused by fire, minimize personal injury and property loss. In the overall arrangement of firefighting, it can be roughly divided into fire smoke exhaust, fire extinguishing, etc., among which fire smoke exhaust is an indispensable item in buildings. It mainly uses smoke exhaust pipes to discharge smoke and dust generated by fire or other problems to avoid smoke and dust accumulation inside the building.

[0003] A fire smoke exhaust duct designed by BIM is published with the Chinese utility model announcement number CN220556204U. The utility model discloses a fire smoke exhaust duct designed by BIM, including a main duct, a secondary duct and a ventilation box. The secondary duct is arranged on the side of the main duct, a temperature sensor is arranged inside the secondary duct, a pressure sensor is arranged at one end of the ventilation cavity of the secondary duct, a ventilation filter is arranged at the contact position between the secondary duct and the main duct, a connecting duct is arranged at one end of the main duct, a ventilation box is arranged at the lower end of the connecting duct, a ventilation fan is installed inside the ventilation box, a ventilation port is opened on the right side of the ventilation box, and a ventilation filter is installed on the right side of the ventilation box. The beneficial effect of the utility model is that a multi-layer protection mechanism is realized through the combined design of the main duct, the secondary duct, the ventilation cavity of the main duct and the ventilation box. A temperature sensor is arranged inside the ventilation cavity of the secondary duct, which can timely monitor temperature abnormalities and avoid high temperature damage to the smoke exhaust duct. A ventilation filter is arranged to effectively filter impurity particles in the gas and keep the ventilation gas clean.

[0004] When using the above scheme, since the ventilation filter has the effect of filtering impurity particles in the gas and keeping the ventilation gas clean, the impurity particles filtered by the ventilation filter will accumulate in the ventilation filter. If the ventilation filter is not cleaned for a long time, it will easily cause the ventilation filter to be blocked, which will not only affect the efficiency of ventilation and smoke exhaust, but also increase the power used by the smoke exhaust fan. Therefore, a smoke exhaust duct for fire protection is now proposed. Utility Model Content

[0005] In order to improve the effect of the ventilation filter plate in filtering impurity particles in the gas and keeping the ventilation gas clean, the impurity particles filtered by the ventilation filter plate will accumulate in the ventilation filter plate. If the ventilation filter plate is not cleaned for a long time, it will easily cause the ventilation filter plate to be blocked, which will not only affect the efficiency of ventilation and smoke exhaust, but also increase the power used by the smoke exhaust fan. The utility model provides a smoke exhaust duct for fire fighting.

[0006] The utility model provides a smoke exhaust duct for fire fighting, adopting the following technical scheme: a smoke exhaust duct for fire fighting, comprising a duct, a mounting plate arranged at one end of the duct for mounting the duct, and a filter plate installed inside the mounting plate for filtering smoke, a hydraulic cylinder is fixedly installed inside the mounting plate, a telescopic end of the hydraulic cylinder is fixedly connected to a first bearing plate, both sides of the first bearing plate are fixedly connected to connecting plates, the other end of the connecting plate is fixedly connected to a second bearing plate, and cleaning rollers are rotatably installed inside the first bearing plate and the second bearing plate.

[0007] By adopting the above technical solution, the first supporting plate is pushed downward by the hydraulic cylinder, and when the first supporting plate moves downward, it will drive the connecting plate and the second supporting plate to move downward. At the same time, during the downward movement of the first supporting plate and the second supporting plate, the first supporting plate and the second supporting plate are internally installed with cleaning rollers to clean and remove dust on the surface of the filter plate, reducing the accumulation of impurities on the filter plate, thereby increasing the exhaust efficiency and reducing the power used by the smoke exhaust fan.

[0009] By adopting the above technical solution, the slide groove can facilitate the downward movement of the first carrying plate, the connecting plate and the second carrying plate, thereby facilitating the cleaning of the filter plate.

[0010] Optionally, a fixing rod is fixedly installed at a corner of the mounting plate away from the hydraulic cylinder, and the fixing rod runs through the first bearing plate and the second bearing plate.

[0011] By adopting the above technical solution, the fixing rod can fix the trajectory of the first supporting plate and the second supporting plate when they move downward, thereby avoiding incomplete cleaning caused by the shaking of the first supporting plate and the second supporting plate.

[0012] Optionally, branch pipes are fixedly installed around the side of the pipeline away from the mounting plate, protective sleeves are fixedly installed on the outer sides of the branch pipes, and the other ends of the branch pipes are fixedly connected to connecting pipes, which are sleeved on the outer sides of the pipeline.

[0013] By adopting the above technical solution, the branch pipe can achieve the gas separation effect when too much smoke and dust accumulate inside the pipe, reducing the possibility of smoke and dust accumulation inside the pipe, while the protective cover facilitates the protection of the branch pipe.

[0014] Optionally, the connecting pipeline forms a communication structure with the pipeline through a branch pipe.

[0015] By adopting the above technical solution, the connecting pipeline achieves the diversion effect of the pipeline through the branch pipe.

[0016] Optionally, a first one-way exhaust valve is fixedly installed inside the branch pipe at one end of the pipeline, and a second one-way exhaust valve is fixedly installed inside the branch pipe at one end of the connecting pipeline.

[0017] By adopting the above technical solution, the first one-way exhaust valve and the second one-way exhaust valve inside the branch pipe can prevent the backflow of smoke inside the branch pipe when the branch pipe is divided.

[0018] Optionally, a smoke detector is fixedly mounted on the outer wall of the pipeline, and the smoke detector is electrically connected to the first one-way exhaust valve and the second one-way exhaust valve.

[0019] By adopting the above technical solution, the smoke detector can detect smoke and dust outside the pipeline. When a lot of smoke and dust accumulates, the first one-way exhaust valve and the second one-way exhaust valve inside the branch pipe can be opened to increase the efficiency of smoke exhaust.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The utility model pushes the first supporting plate downward through the hydraulic cylinder, and when the first supporting plate moves downward, it will drive the connecting plate and the second supporting plate to move downward. At the same time, during the downward movement of the first supporting plate and the second supporting plate, the first supporting plate and the second supporting plate are internally installed with cleaning rollers to clean and remove dust on the surface of the filter plate, thereby reducing the accumulation of impurities on the filter plate, thereby increasing the exhaust efficiency and reducing the power used by the smoke exhaust fan.

[0022] 2. The branch pipe of the utility model can achieve the effect of air separation when there is too much smoke and dust accumulation inside the pipe, reducing the possibility of smoke and dust accumulation inside the pipe, and the smoke detector can detect the smoke and dust outside the pipe. When the smoke and dust accumulates more, the first one-way exhaust valve and the second one-way exhaust valve inside the branch pipe can be opened to increase the efficiency of smoke exhaust. The first one-way exhaust valve and the second one-way exhaust valve inside the branch pipe can also be used to avoid the backflow of smoke and dust inside the branch pipe when the branch pipe is diverted.
