Description

Fire-fighting ventilation pipeline

Technical Field

The utility model relates to a fire-fighting ventilation pipeline, and belongs to the technical field of fire-fighting pipelines.

Background

The installation requirement of the fire-fighting smoke prevention and exhaust system can be checked in the design specification of GB50243-2002 of the quality inspection and acceptance Specification of ventilation and air-conditioning engineering construction. The galvanized iron sheet is needed to be adopted in the manufacturing of the fire-fighting smoke-preventing and discharging air pipe, the medium pressure is needed to be selected in the thickness of the iron sheet air pipe of the smoke discharging system, the pipeline, the air port, the valve and the like in the smoke preventing and discharging system are manufactured by adopting nonflammable materials, and the thickness of the galvanized iron sheet is different according to the different diameters and lengths of the air pipes, for example: a galvanized iron sheet of 0.75 is used for 630mm, and so on 1000-1250 (1.0), 1250-2000 (1.2). The design of the smoke prevention and exhaust system shows that the thickness of the steel plate of the spiral air pipe can be properly reduced by 10-15%. The thickness of the air duct steel plate of the smoke exhaust system can be pressed to the high-pressure system. The thickness of the air duct steel plate of the special dust removal system meets the design requirement. The embedded pipe is not suitable for underground civil air defense and fireproof partition walls.

The Chinese patent publication discloses a fire-fighting ventilation pipeline, the name of which is CN214536800U, the structure description is that, chute 2 is all opened on the corresponding both sides of first ventilation pipe 1 inner wall, the inside sliding connection of chute 2 has slider 3, two fixedly connected with backup pad 4 between the slider 3, the top of backup pad 4 and with the inside joint of first ventilation pipe 1 have filter screen 5, the one end of filter screen 5 and second ventilation pipe 6 all fixedly connected with first connecting piece 7, the one end that filter screen 5 and second ventilation pipe 6 kept away from first connecting piece 7 all fixedly connected with second connecting piece 22, the inside rotation of first ventilation pipe 1 is connected with first connecting rod 8, the one end of first connecting rod 8 is rotationally connected with second connecting rod 9 and third connecting rod 10 respectively, the inside rotation of first ventilation pipe 1 is connected with fourth connecting rod 11, the one end of third connecting rod 10 and fourth connecting rod 11 rotationally connect, one side fixed mounting of first ventilation pipe 1 has second motor 21, the one side of second motor 21 and the output end of second motor 11 and fourth connecting rod 11 fixedly connected with first connecting rod 13, the one side of second motor 21 and fourth connecting rod 11 fixedly connected with first connecting rod 13.

The beneficial effects of the utility model are as follows: this fire control air pipe drives the removal of slider and thereby controls the filter screen and goes up and down through the rotation of lead screw, and the filter screen is convenient for the change of filter screen with the backup pad joint, is favorable to reducing staff's work burden, replaces the manpower by electric power, accelerates the change efficiency of filter screen when save time, guarantee fire control work go on and public safety.

The disadvantage of this patent lies in that first ventilation pipe and second ventilation pipe are in the same place through the bolt butt joint by first connecting piece, and single structure, one side fixed mounting of connecting plate have first motor, and the output fixedly connected with cleaning brush of first motor, fixed cleaning structure only can sweep the ventilation pipe inner wall that the cleaning brush contacted, and other positions can't clean, and is impractical. If the motor is arranged on the side surface of the pipeline, the motor needs to be correspondingly supported and positioned, the weight of the pipeline is increased, and the pipeline can only be fixed on the ground and cannot be hung at high altitude for smoke discharge.
