Description

Technical Field

[0001] This utility model relates to the field of fireproof windows, and in particular to a fireproof window for ship cabins. Background Technology

[0002] Fire-resistant windows are windows made of steel frames, steel sashes, and fire-resistant glass, designed to isolate and prevent the spread of fire. They are typically installed in openings or skylights on the exterior walls of buildings where fire separation distances are insufficient, in areas requiring observation on firewalls or fire-resistant partitions within buildings, and in exterior wall openings where vertical fire spread needs to be prevented.

[0003] Common fireproof windows for ships are designed with only a single layer of fireproof glass, which has poor sound insulation and can interfere with normal conversations between crew members and reduce environmental comfort. Utility Model Content

[0004] This application provides a fireproof window for ship cabins, which has good sound insulation and does not obstruct the view.

[0005] The technical solution for a fireproof window for ship cabins provided in this application is as follows:

[0006] A fireproof window for ship cabins includes a window frame and a fireproof glass panel, wherein the fireproof glass panel is bolted to the window frame. The window frame is characterized by further including a sound insulation structure, which comprises multiple sound insulation strips and a driving device. A window sill extends outward from one end of the window frame, and the multiple sound insulation strips are vertically rotatably connected to the window sill. The driving device drives the sound insulation strips to rotate. When the sound insulation strips rotate until their length direction is parallel to the height direction of the window frame, the sound insulation strips form a sound insulation layer, which reduces the propagation of noise.

[0007] With the above technical solution, when a soundproof environment is required, the operator can rotate the soundproof strips to form a soundproof layer by driving the device, thereby reducing noise interference with normal conversations between crew members and reducing environmental comfort; when it is necessary to look out the window, the operator can rotate the soundproof strips that form the soundproof layer by another 90 degrees to reduce their obstruction of the view.

[0008] Preferably, the driving device includes multiple rotating shafts, multiple turntables, a transmission belt, and a drive chain. The multiple rotating shafts are vertically inserted one-to-one into multiple sound insulation strips, and the multiple rotating shafts are vertically rotatably connected to the window sill. The multiple turntables are respectively inserted one-to-one onto the top ends of the multiple rotating shafts. The transmission belt is sleeved on the multiple rotating shafts and abuts against the top surface of the turntables. The drive chain is disposed on the rotating shafts and is used to pull the rotating shafts to rotate.

[0009] With the above technical solution, when the drive chain drives the shaft to rotate, the friction drives the transmission belt to move, thereby driving the remaining shafts to rotate in the same direction, ultimately achieving the effect of rotating all the sound insulation strips in the same direction and synchronously.

[0010] Preferably, the rotating shaft includes a plurality of drive shafts, the turntable on the drive shaft has an annular groove, the drive chain is wound around the annular groove, and the drive chain is used to drive the drive shaft to rotate in the same direction.

[0011] Through the above technical solution, the ring groove restricts the position of the drive chain, thereby ensuring that the drive chain can stably drive the drive shaft to rotate when the drive chain is pulled.

[0012] Preferably, the sound insulation strip is made of polyester fiber, and a metal layer is also provided on the side facing the fireproof glass panel, the metal layer being made of aluminum foil.

[0013] Through the above technical solution, due to the fine structure of polyester fibers and the presence of many pores and capillaries inside, when sound waves enter these pores, they will undergo multiple reflections, scattering, and absorptions, thus playing a certain degree of sound insulation role; while the metal layer has a good reflection and isolation effect on sound waves. When sound waves encounter the metal layer, most of the sound wave energy will be reflected back, thereby improving the sound insulation performance of the sound insulation strip.

[0014] Preferably, the window cleaning structure is also included, which includes a sponge strip, a drive rope, and a resetting component. The sponge strip is located between the fireproof glass panel and the sound insulation strip, and the sponge strip abuts against the fireproof glass panel. One end of the drive rope is set on the top surface of the sponge strip, and the other end is set towards the outer side of the top surface of the window sill. The resetting component is used to abut the sponge strip against the bottom surface inside the window frame. When the drive rope is pulled, the sponge strip moves vertically upward.

[0015] The above technical solution addresses the issue that the side of the fireproof glass panel facing the sound insulation structure is difficult to clean due to the sound insulation structure. The window cleaning structure uses a cleaning sponge strip against the side of the fireproof glass panel facing the sound insulation structure, and a drive rope and a reset component to make the sponge strip move vertically back and forth on the fireproof glass panel to assist the operator in cleaning the fireproof glass panel, thereby reducing the difficulty in cleaning the side of the fireproof glass panel facing the sound insulation structure.

[0016] Preferably, the reset component includes two springs and two drive blocks. The two drive blocks are respectively fixed to both ends of the sponge strip. The inner walls on both sides of the window frame are vertically provided with guide grooves. The drive blocks slide in the guide grooves. One end of each of the two springs is respectively set on the top surface of the drive blocks, and the other end is respectively set on the inner wall of the window frame. The springs are always kept in a compressed state.

[0017] Through the above technical solution, the cooperation between the drive block and the guide groove reduces the possibility of the sponge strip twisting or detaching from the fireproof glass plate during vertical movement, thus ensuring stability during operation; while the spring is responsible for pushing the sponge strip along the guide groove to abut against the bottom surface inside the window frame after the operator releases the drive rope.

[0018] Preferably, it also includes a guide structure, which includes two fixed pulleys and a guide block. The fixed pulleys and the guide block are located on the top surface inside the window frame and are set on the window sill. The two fixed pulleys are respectively located on both sides of the guide block and are located on the movement path of the drive rope. The drive rope is not fixed to the end of the sponge strip and passes through the fixed pulleys and the guide block in sequence toward the outside of the window sill.

[0019] Through the above technical solution, the two fixed pulleys change the direction of force on the drive rope, making it easier and smoother for the operator to pull the sponge strip. At the same time, the fixed pulleys and guide blocks restrict the movement path of the drive rope to ensure stability during operation.

[0020] The main technical effects of this utility model are reflected in the following aspects:

[0021] 1. This utility model incorporates a sound-insulating strip made of polyester fiber, with a metal layer made of aluminum foil fixed to the side facing the fireproof glass panel. Due to the dense structure of polyester fiber and the presence of numerous pores and capillaries, sound waves entering these pores undergo multiple reflections, scattering, and absorption, thus providing a certain degree of sound insulation. The metal layer, on the other hand, has excellent sound reflection and isolation properties; when sound waves encounter the metal layer, most of the sound wave energy is reflected back, thereby improving the sound insulation performance of the sound-insulating strip and reducing the impact of noise on operators.

[0022] 2. This utility model, by setting a driving device, allows the operator to switch between two states: maintaining a soundproof environment and reducing obstruction of vision.

[0023] 3. This utility model, by setting up a window cleaning structure, uses a drive rope and a reset component to make the sponge strip move vertically back and forth on the fireproof glass panel to assist the operator in cleaning the fireproof glass panel, thereby reducing the difficulty in cleaning the side of the fireproof glass panel facing the sound insulation structure.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-6 The specific embodiments of this utility model will be further described in detail to make the technical solution of this utility model easier to understand and master.

[0032] This application discloses a fireproof window for ship cabins:

[0033] Reference Figure 1-3 A fireproof window for ship cabins includes a window frame 1 and a fireproof glass panel 2. The fireproof glass panel 2 is bolted to the window frame 1. It also includes a sound insulation structure 3, which comprises multiple sound insulation strips 31 and a driving device 32. A window sill 14 extends outward from one end of the window frame 1. The multiple sound insulation strips 31 are vertically rotatably connected to the window sill 14. The driving device 32 drives the sound insulation strips 31 to rotate. When the sound insulation strips 31 rotate until their length direction is parallel to the height direction of the window frame 1, the sound insulation strips 31 form a sound insulation layer, which reduces noise transmission. When a soundproof environment is required, the operator rotates the sound insulation strips 31 using the driving device 32 to form a sound insulation layer, thereby reducing noise interference with normal conversations between crew members and reducing environmental comfort. When it is necessary to look out the window, the operator rotates the sound insulation strips 31 forming the sound insulation layer by another 90 degrees to reduce obstruction of the view.

[0034] Reference Figure 2-4The drive unit 32 includes multiple rotating shafts 321, multiple turntables 323, a transmission belt 325, and a drive chain 326. The multiple rotating shafts 321 are vertically threaded one-to-one through multiple sound insulation strips 31, and are vertically rotatably connected to the window sill 14. The multiple turntables 323 are respectively threaded one-to-one through and fixed to the top of the multiple rotating shafts 321. The transmission belt 325 is sleeved on the multiple rotating shafts 321 and abuts against the top surface of the turntables 323. The drive chain 326 is mounted on the rotating shafts 321 and is used to pull the rotating shafts 321 to rotate. When the drive chain 326 drives the rotating shafts 321 to rotate, friction causes the transmission belt 325 to move, thereby driving the remaining rotating shafts 321 to rotate in the same direction, ultimately achieving the effect of rotating all the sound insulation strips 31 in the same direction and synchronously.

[0035] The rotating shaft 321 includes several drive shafts 322. A turntable 323 on each drive shaft 322 has an annular groove 324. A drive chain 326 is wound around the annular groove 324 and is used to drive the drive shaft 322 to rotate in the same direction. The annular groove 324 restricts the position of the drive chain 326, thereby ensuring that the drive chain 326 can stably drive the drive shaft 322 to rotate when pulled.

[0036] Reference Figure 3 The sound insulation strip 31 is made of polyester fiber, and a metal layer 311 made of aluminum foil is fixed on the side facing the fireproof glass panel 2. Due to the dense structure of polyester fiber and the presence of many pores and capillaries inside, sound waves will undergo multiple reflections, scattering, and absorption when they enter these pores, thus playing a certain role in sound insulation. The metal layer 311 has a good reflection and isolation effect on sound waves. When sound waves encounter the metal layer 311, most of the sound wave energy will be reflected back, thereby improving the sound insulation performance of the sound insulation strip 31.

[0037] Reference Figure 3 and Figure 5-6 The system also includes a window cleaning structure 4, which comprises a sponge strip 41, a drive rope 42, and a resetting member 43. The sponge strip 41 is located between the fireproof glass panel 2 and the sound insulation strip 31, and abuts against the fireproof glass panel 2. One end of the drive rope 42 is fixed to the top surface of the sponge strip 41, and the other end is set towards the outer side of the top surface of the window sill 14. The resetting member 43 is used to abut the sponge strip 41 against the bottom surface inside the window frame 1. Due to the sound insulation structure 3, the side of the fireproof glass panel 2 facing the sound insulation structure 3 is difficult to clean. The window cleaning structure 4 uses a cleaning sponge strip 41 abutting against the side of the fireproof glass panel 2 facing the sound insulation structure 3, and uses the drive rope 42 and the resetting member 43 to make the sponge strip 41 move vertically back and forth on the fireproof glass panel 2 to assist the operator in cleaning the fireproof glass panel 2, thereby reducing the difficulty in cleaning the side of the fireproof glass panel 2 facing the sound insulation structure 3.

[0038] Reference Figure 5 The reset component 43 includes two springs 431 and two drive blocks 432. The two drive blocks 432 are respectively fixed to both ends of the sponge strip 41. Guide grooves 15 are vertically opened on both sides of the inner wall of the window frame 1. The drive blocks 432 slide in the guide grooves 15. One end of each of the two springs 431 is fixed to the top surface of the drive block 432, and the other end is fixed to the inner wall of the window frame 1. The springs 431 are always kept in a compressed state. The cooperation between the drive blocks 432 and the guide grooves 15 reduces the possibility of the sponge strip 41 twisting or detaching from the fireproof glass plate 2 during vertical movement, ensuring stability during operation. The springs 431 are responsible for pushing the sponge strip 41 along the guide grooves 15 to abut against the bottom surface inside the window frame 1 after the operator releases the drive rope 42.

[0039] Reference Figure 6 The system also includes a guide structure 44, which comprises two fixed pulleys 441 and a guide block 442. The fixed pulleys 441 and guide block 442 are located on the inner top surface of the window frame 1 and fixed to the window sill 14. The two fixed pulleys 441 are located on either side of the guide block 442 and along the path of the drive rope 42. The end of the drive rope 42 not fixed to the sponge strip 41 passes through the fixed pulleys 441 and guide block 442, extending outwards towards the window sill 14. The two fixed pulleys 441 change the direction of force on the drive rope 42, making it easier and smoother for the operator to pull the sponge strip 41. Simultaneously, the fixed pulleys 441 and guide block 442 restrict the path of the drive rope 42, ensuring stability during operation.

[0040] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
