Description

Technical Field

[0001] The present invention relates to the technical field of soundproof and fireproof doors, and in particular to a lightweight ship-based active noise reduction and fireproof and soundproof door. Background Art

[0002] Based on the long-term working environment of ships at sea, the doors used in cabins need to meet the fire protection requirements of ships and have good sound insulation to ensure the rest environment inside the cabin. In addition to the functions of ordinary doors, fire doors need to prevent the spread of fire and smoke. In the event of a fire, the spread of fire can be prevented within a certain period of time to ensure that personnel have more time to evacuate. The existing traditional ships use a rock wool sandwich sound insulation and fire door structure. This structure can achieve passive sound insulation and noise reduction through rock wool and plate structure, and at the same time achieve fire protection based on the non-combustible characteristics of rock wool. Due to the use of passive noise reduction, the sound insulation of the sound insulation and fire door is directly positively correlated with the thickness and density of the plate and rock wool. If high-quality sound insulation is required, thick door panels are required. Because the door panels of ships are currently developing in the direction of lightweight, the passive noise reduction of traditional sound insulation and fire doors is difficult to meet the increasing sound insulation needs of ships under the condition of thinning and lightening. Due to the need for its fire protection characteristics, it is impossible to achieve better noise reduction and fire protection effects, which reduces the crew's feeling when resting.

[0003] For example, a marine fireproof door enclosed door provided by patent publication number CN113863827A includes a door frame, the front left side of the door frame is rotatably connected to the door body, the middle of the rear inner wall of the door body is rotatably connected to the rotating shaft, the middle of the shaft of the rotating shaft is fixedly connected to a gear, and the left and right ends of the gear are meshed and connected with tooth plates, the left and right inner walls of the door body are fixedly connected to the left and right ends of a plurality of reinforcing plates, the outer end of the tooth plate is fixedly connected to a pressure plate, the front end of the rotating shaft passes through the front end of the door body and is fixedly connected to a turntable, the middle inner wall of the right end of the door frame is fixedly connected to an electric cylinder, the driving end of the electric cylinder is fixedly connected to a limit plate, the upper and lower left ends of the limit plate are fixedly connected to one end of the plug block, the other end of the plug block passes through the door frame and extends to the outside, the rotating shaft and the gear are driven to rotate by rotating the turntable, the tooth plate and the slider are driven to move up and down by the rotation of the gear, and in the event of a fire, the pressure plate and the sealing gasket are driven to move by the tooth plate, and the gap between the door body and the door frame is filled by the sealing gasket. The fire doors are sealed to prevent smoke or harmful gases from passing through the gap and spreading. The sealing effect is good and the sealing pad can be reused. The ambient temperature is monitored in real time through the temperature sensor. When a fire occurs and the ambient temperature rises to the set safety value, the alarm will sound an alarm and give a timely warning. However, the above-mentioned fire doors do not have a good sound insulation effect. In the daily navigation process, sound insulation is very important. The lack of good sound insulation will cause the ears of the relevant people to be damaged by noise for a long time, causing restlessness, tinnitus or deafness, which is not conducive to the health of the relevant personnel. When closing the door, when the force of closing the door is large, a large sound will be generated between the door and the door frame. At the same time, long-term impact will cause damage to the door panel, resulting in poor fireproof effect of the fire door. At the same time, when a fire occurs, flames and thick smoke will burst out from the edge of the door gap of the existing fire door, resulting in poor fire and smoke prevention effect, which greatly reduces the practicality. Therefore, it is very urgent to develop a fireproof and soundproof door with fireproof performance and active noise reduction. Summary of the invention
