Description

Technical Field

[0001] The utility model relates to the technical field of subway fire ventilation, in particular to a subway fire ventilation and smoke exhaust device. Background Art

[0002] The subway fire ventilation and smoke exhaust device is a device specially used for subway fire fighting. Its main function is to quickly discharge toxic smoke and hot air from subway tunnels or stations through smoke exhaust fans and other equipment when a fire occurs, so as to reduce the impact of smoke on personnel escape and fire rescue.

[0003] In the actual use of subway fire ventilation and smoke exhaust devices, long-term use will cause too much dust to accumulate on the surface of the dustproof net inside the smoke exhaust device, which will slow down the smoke exhaust efficiency and require regular maintenance by personnel. Affected by the installation position of the smoke exhaust device, the staff will face the situation of climbing up and down, which increases the difficulty of internal maintenance of the smoke exhaust device. Hereby, a subway fire ventilation and smoke exhaust device is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a subway fire ventilation and smoke exhaust device, which solves the problem in the prior art that after long-term use, too much dust accumulates on the surface of the dustproof net inside the smoke exhaust device, thereby slowing down the smoke exhaust efficiency and requiring regular maintenance by personnel. Affected by the installation position of the smoke exhaust device, the staff will face the situation of climbing up and down, thereby increasing the difficulty of internal maintenance of the smoke exhaust device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A subway fire ventilation and smoke exhaust device comprises a pipe, both ends of the pipe are fixedly connected with a butt pipe, the inner cavity of the pipe is detachably connected with a mounting outer frame, the inner cavity of the mounting outer frame is installed with a fan, one side of the mounting outer frame is fixedly connected with a dust screen, one side of the pipe and one side of the mounting outer frame are rotatably connected with a baffle plate through a hinge, one side of the dust screen is provided with a screw rod, the outer ring of the screw rod is provided with a threaded sleeve, and one side of the outer ring of the threaded sleeve is fixedly connected with a brush plate.

[0007] Preferably, a plurality of tamping rods are fixedly connected to the bottom of the brush plate, a through groove is provided at the bottom of the inner cavity of the pipe and below the brush plate, and an inner wall on one side of the through groove is rotatably connected to a movable plate via a spring hinge.

[0008] Preferably, a motor is installed on the top of the pipe, the bottom of the screw rod is rotatably connected to the bottom of the inner cavity of the pipe through a rotating shaft, and the top of the screw rod passes through the top of the inner cavity of the pipe through a sleeve and is drivingly connected to the output shaft of the motor.

[0009] Preferably, a sliding rod is provided on one side of the screw rod, and both ends of the sliding rod are respectively fixedly connected to the inner walls of the adjacent pipes. The outer ring of the sliding rod is provided with a sliding sleeve, and one side of the outer ring of the sliding sleeve is fixedly connected to one side of the adjacent brush plate.

[0010] Preferably, one side of the brush plate is in contact with one side of the dustproof net.

[0011] Preferably, mounting frames are fixedly connected to both sides of the bottom of the pipeline.

[0012] The utility model has at least the following beneficial effects:

[0013] When people use it, it is connected to other pipelines through the butt joint. Driven by the fan, the air inside the pipeline has a fixed direction of transmission force. When the smoke passes through the dustproof net, the dustproof net can effectively intercept the particles and some dust mixed in the smoke, so that clean air can be discharged outward. After long-term use, more dust will be adsorbed on the surface of the dustproof net. Driven by the motor, the screw rod rotates, so that the screw sleeve drives the brush plate to move longitudinally. Through physical contact, the brush on the brush plate scratches the dustproof net, so that the dust adsorbed on the dustproof net is processed. When the brush plate moves to the bottom of the inner cavity of the pipe, the tamping rod will resist the movable plate, causing the movable plate to rotate, so that the dust accumulated on the movable plate is discharged outward through the through groove. Randomly, the brush plate is flipped by the motor to restore its initial position. Driven by the spring hinge, the movable plate restores its initial position. Through the structural design, the dust net can be quickly cleaned and maintained by personnel after long-term use. The maintenance operation steps are simple and easy to use, which reduces the cost of personnel learning and use. The cleaned dust can be actively discharged outward, and the whole cleaning process reduces the participation of personnel.

[0014] The utility model also has the following beneficial effects:

[0015] The setting of the movable plate not only ensures the sealing of the pipeline, but also makes it convenient for personnel to discharge the cleaned dust to the outside of the pipeline. The setting of the screw rod allows the screw sleeve to have movement transmission force in two directions. The setting of the sliding sleeve and the sliding rod ensure that the screw sleeve will not rotate with the screw rod. The setting of the dustproof net can process and intercept the dust in the flue gas. The setting of the mounting frame ensures the installation stability of the pipeline.
