[0004] However, the above-mentioned utility model cannot filter particulate matter from dense smoke during fire fighting, and it cannot protect the interior of the fire smoke exhaust device when not in operation. Therefore, a rapid fire smoke exhaust device is proposed to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a rapid fire smoke extraction device, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid fire-fighting smoke exhaust device, comprising a mounting frame, an mounting cylinder above the mounting frame, a dual-head drive motor installed inside the mounting cylinder, fan blades connected to the two output ends of the dual-head drive motor and a rotating cylinder respectively, several sets of partitions arranged around the rotating cylinder, each set of partitions having ventilation holes, and filters installed on the ventilation holes, the several sets of partitions being equally spaced inside the mounting cylinder, several water spray holes arranged on the outside of the rotating cylinder, the end of the rotating cylinder away from the dual-head drive motor rotating through the mounting cylinder and having a water inlet pipe provided thereon, the rotating cylinder being rotatably connected to the water inlet pipe.

[0007] Preferably, the output end of the dual-head drive motor is provided with three sets of guide rails. The three sets of guide rails are located on the side of the fan blade away from the dual-head drive motor. Each set of guide rails is provided with a guide rod inside. A protective plate is slidably mounted on the guide rod. A spring is sleeved on the outside of the guide rod. The two ends of the spring are connected to the guide rail and the protective plate, respectively.

[0008] Preferably, the partition is provided in four sets, with ventilation holes of two sets of partitions located below the partition and ventilation holes of two sets of partitions located above the partition. The partitions with ventilation holes at different positions in each set are staggered. The ventilation holes of the partition group closer to the dual-head drive motor are located below the partition, and the ventilation holes of the partition group farther away from the dual-head drive motor are located above the partition.

[0009] Preferably, a protective net is provided between the fan blade and the protective plate, and the output end of the dual-head drive motor rotates through the center of the protective net.

[0011] Preferably, the mounting cylinder has a drainage hole at its bottom, located below the rotating cylinder.

[0012] Preferably, the three sets of protective plates are coaxially arranged with the dual-head drive motor, the rotating drum, and the fan blades.

[0013] This utility model provides a rapid fire smoke extraction device. It has the following beneficial effects:

[0014] 1. This rapid fire-fighting smoke exhaust device connects to a rotating drum at the output end of a dual-head drive motor. The rotating drum has four sets of partitions arranged at equal intervals inside the installation cylinder. Ventilation holes for two sets of partitions are located below and above the partitions. The partitions with ventilation holes at different positions are staggered. Several water spray holes are located on the outside of the rotating drum. The placement of filters at different positions on the partitions allows dense smoke to pass through the installation cylinder along a fixed path. The filters block particulate matter in the smoke. Water sprayed from the rotating drum further combines with the particulate matter in the smoke and settles, then is discharged with the water from the drain hole at the bottom of the installation cylinder, effectively treating the particulate matter in the smoke.

[0015] 2. This rapid fire-fighting smoke exhaust device features three sets of guide rails at the output end of a dual-head drive motor. These guide rails are located on the side of the fan blades furthest from the motor. Each guide rail contains a guide rod with a protective plate sliding on it. A spring is fitted around the outside of the guide rod, with both ends connected to the guide rail and the protective plate, respectively. During operation, the dual-head drive motor rotates, and the protective plate slides on the guide rod under centrifugal force. The three sets of protective plates move away from each other, opening the end face of the installation cylinder and allowing smoke to enter under the action of the fan blades. When operation stops, the dual-head drive motor stops rotating, and the three sets of protective plates move closer together under the action of the springs, closing the protective plates and preventing dust and other debris from entering the installation cylinder when it is not in operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] This utility model embodiment provides a rapid fire smoke exhaust device, such as... Figure 1-5As shown, the device includes a mounting frame 1, with a mounting cylinder 3 positioned above the mounting frame 1. A dual-head drive motor 6 is installed inside the mounting cylinder 3. The two output ends of the dual-head drive motor 6 are respectively connected to fan blades 5 and a rotating cylinder 9. Several sets of partitions 7 are arranged around the rotating cylinder 9. The partitions 7 are movably inserted into the interior of the mounting cylinder 3. Each set of partitions 7 has ventilation holes, and a filter screen 8 is installed on the ventilation holes to ensure that the smoke flows from inside the mounting cylinder 3, passes through the ventilation holes, and passes through the partitions 7. Several sets of partitions 7 are arranged at equal intervals inside the mounting cylinder 3. Several water spray holes are arranged on the outside of the rotating cylinder 9. The end of the rotating cylinder 9 away from the dual-head drive motor 6 rotates through the mounting cylinder 3 and is provided with a water inlet pipe 10. The rotating cylinder 9 and the water inlet pipe 10 are rotatably connected. Four sets of partitions 7 are provided. Two sets of partitions 7 have ventilation holes located below them, and two sets have ventilation holes located above them. The partitions 7 with ventilation holes at different positions are staggered. The ventilation holes of the partition 7 closest to the dual-head drive motor 6 are located below, and the ventilation holes of the partition 7 furthest from the dual-head drive motor 6 are located above. A protective net 4 is provided between the fan blade 5 and the protective plate 11. The output end of the dual-head drive motor 6 rotates through the center of the protective net 4. Both sides of the bottom of the mounting frame 1 are equipped with rotatable casters 2. A drainage hole is provided at the bottom of the mounting cylinder 3, located below the rotating cylinder 9, to facilitate the drainage of water thrown out of the rotating cylinder 9 into the mounting cylinder 3. The output end of the dual-head drive motor 6 is equipped with three sets of guide rails 12, located on the side of the fan blade 5 away from the dual-head drive motor 6. Each set of guide rails 12 contains a guide rod 13, on which a protective plate 11 slides. A spring 14 is sleeved on the outside of the guide rod 13, with both ends of the spring 14 connected to the guide rail 12 and the protective plate 11, respectively. When the dual-head drive motor 6 rotates, it drives the three sets of guide rails 12 to rotate around the output end of the dual-head drive motor 6. During rotation, the protective plate 11 slides on the guide rod 13 under centrifugal force, opening the end face of the mounting cylinder 3 and allowing smoke to enter the mounting cylinder 3 under the action of the fan blade 5. The three sets of protective plates 11 are coaxially arranged with the dual-head drive motor 6, the rotating cylinder 9, and the fan blade 5.

[0024] Working principle: During use, the dual-head drive motor 6 is started, which drives the protective plate 11, fan blades 5, and rotating drum 9 to rotate. After the water inlet pipe 10 is connected to the water supply equipment, water is supplied to the rotating drum 9 and sprayed out from the sprinkler hole. When the protective plate 11 rotates, it slides on the guide rod 13 under the action of centrifugal force. The end face of the mounting cylinder 3 opens, allowing the smoke to enter the mounting cylinder 3 under the action of the fan blades 5. The dense smoke enters the interior of the mounting cylinder 3 and moves towards the baffle 7. The four sets of baffles 7 are staggered, so that after the dense smoke enters the mounting cylinder 3, it exits through the ventilation hole below the leftmost baffle 7. The smoke passes through the other three sets of baffles 7 in sequence. The filter screens 8 at different positions on the baffles 7 allow the smoke to pass through the mounting cylinder 3 along a fixed path. The filter screens 8 block the particulate matter in the smoke. The water sprayed from the rotating cylinder 9 further combines with the particulate matter in the smoke and settles. The water is discharged from the drain hole at the bottom of the mounting cylinder 3. When the machine stops working, the dual-head drive motor 6 stops rotating, and the three sets of protective plates 11 move closer to each other under the action of the spring 14, so that the protective plates 11 are closed to prevent dust and other debris from entering the interior of the mounting cylinder 3 when it is not in operation.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
