Description

Technical Field

[0001] This utility model relates to the field of shipbuilding, specifically to a ship air intake filtration device. Background Art

[0002] Passenger-cargo ships are vessels that transport both passengers and a significant amount of cargo, prioritizing passenger transport over cargo transport. Their design and structure must meet both passenger comfort and safety needs while also accommodating cargo loading and transport requirements. Passenger-cargo ships typically have high speeds and large passenger capacities, with tall superstructures for passenger cabins and essential living facilities. Furthermore, they are equipped with ample life-saving and firefighting equipment to ensure the safety of both passengers and cargo. Passenger-cargo ships play a vital role in maritime transport, especially on routes requiring the simultaneous transport of passengers and cargo. However, because passenger-cargo ships must carry both passengers and cargo, safety and comfort must be fully considered during their design and operation.

[0003] To ensure air circulation and maintain suitable environmental conditions inside ships, small passenger and cargo ships rely on natural ventilation, mainly through windows on the ship, utilizing wind and temperature differences to achieve natural airflow. However, this is affected by external weather conditions. During actual navigation, especially at sea or in heavily polluted areas, the outside air contains a large amount of dust and particulate matter. These impurities can easily enter the ship's interior through the windows, affecting the air quality of the crew's living and working environment. In addition, prolonged rain and strong winds can easily cause window frames to deform, corrode, or be damaged, and the sealing strips to age and fail, resulting in a decrease in the window's sealing performance and even preventing the windows from being completely closed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a ship air intake filtration device to solve the problems of impurities easily entering the ship's interior through the windows, affecting the air quality of the crew's living and working environment, and the window frame easily deforming, corroding, or being damaged due to prolonged rain and strong winds, as well as the aging and failure of the sealing strips. It is convenient to use.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A ship air intake filtration device includes a folding windproof window, an external filter window disposed in front of the folding windproof window, and an internal extension plate disposed behind the folding windproof window. The folding windproof window is connected to the internal extension plate, and the internal extension plate has an internal open slot for ventilation.

[0007] The folding windproof window includes a profile window frame with vents, two folding shielding components movably disposed in the vents of the profile window frame, and an adjustment component that drives the two folding shielding components to unfold or fold. When the two folding shielding components are unfolded, they shield the vents of the profile window frame. When the two sets of folding window frames are folded, they open the vents of the profile window frame. The vents on the profile window frame correspond to the built-in opening slots.

[0008] Furthermore, the adjustment assembly includes a ring-shaped traction rope, a first traction disc, a second traction disc, and a third traction disc. A horizontal extension connecting plate is provided at the top of one side facade of the outline window frame. The first traction disc is rotatably mounted on the extension connecting plate. A third traction disc is installed in the middle of the other side facade of the outline window frame, and two mounting slots are opened at the top of this side facade. A second traction disc is installed in each of the two mounting slots. The axis of the first traction disc is along the vertical direction, the axis of the second traction disc is along the front-back direction, and the axis of the third traction disc is along the left-right direction. The two ends of the traction rope are respectively wound around the first traction disc and the third traction disc. The traction rope is divided into two parts and is wound around the two second traction discs respectively. A rotating handle is connected to the third traction disc.

[0009] Furthermore, a built-in slide bar is installed at the top of the inner side of the outline window frame. Several collars are provided at the upper end of each folding shielding assembly. The collars are fitted onto the built-in slide bar. A connecting block is fixed to the part of the traction rope between the first traction disc and one of the second traction discs. Another connecting block is fixed to the part of the traction disc between the first traction disc and the other second traction disc. The two connecting blocks are respectively fixed to one of the collars on the two folding shielding assemblies. The traction rope drives the two connecting blocks to move in the same direction, thereby folding or unfolding the two folding shielding assemblies in a synchronized manner.

[0010] Furthermore, the folding shielding assembly includes multiple vertically spaced transition strips, with a splicing strip between each pair of adjacent transition strips. The splicing strip is hinged to the transition strip, and a connecting rod is connected to the upper end of some transition strips. The end of the connecting rod near the built-in slide rod is provided with the collar sleeved on the built-in slide rod.

[0011] Furthermore, the connecting bar and transition plate on each folding shielding assembly that are furthest from another folding shielding assembly are fixedly connected to the inner wall of the outline window frame, and the collar on each folding shielding assembly that is closest to another folding shielding assembly is connected to one of the connecting blocks.

[0012] This utility model has the following beneficial effects:

[0013] This utility model discloses a ship air intake filtration device, the window of which includes a folding windproof window and an external filter window. The opening and closing of the folding windproof window is controlled by a two-way folding method. The adjustment of the window is completed from the inside, which avoids the restriction of ship space caused by the internal window opening and also prevents the window from being affected by strong winds caused by the external window opening.

[0014] When the two folding shielding components of the folding windproof window are pulled in the opposite direction by the traction rope, the corresponding two sets of splicing strips gradually separate and the adjacent splicing strips fold together, and the two folding shielding components open from the middle to both sides of the window; the reverse operation of the traction rope will shield the window.

[0015] This utility model discloses a ship air intake filtration device. On the one hand, it allows natural ventilation through an external filter window, avoiding the high-speed navigation process and ensuring basic air intake needs. On the other hand, many impurities will remain on the surface of the external filter window during use. The folding shielding component makes it easy to clean when folded. This air intake method is suitable for passenger and cargo ships, is easy to operate, and effectively utilizes natural resources. Attached Figure Description

[0024] A ship's air intake filtration device includes a folding windproof window, an external filter window disposed in front of the folding windproof window, and an internal extension plate disposed behind the folding windproof window. The folding windproof window is connected to the internal extension plate, and the internal extension plate has an internal opening for ventilation. The folding windproof window includes a window frame with a vent (this vent is the window in the middle of the outline window frame; in this embodiment, the outline window sill is square, and the vent is also square. If the outline window frame adopts other shapes, the shape of the vent will also change accordingly), two folding shielding components movably disposed in the vent of the outline window frame, and an adjusting component that drives the two folding shielding components to unfold or fold. When the two folding shielding components are unfolded, they shield the vent of the outline window frame. When the two sets of folding window frames are folded, they open the vent of the outline window frame. The vent on the outline window frame corresponds to the internal opening.

[0025] The adjustment assembly includes a ring-shaped traction rope, a first traction disc, a second traction disc, and a third traction disc. A horizontal extension connecting plate is provided at the top of one side facade of the outline window frame. The first traction disc is rotatably mounted on the extension connecting plate. The third traction disc is installed in the middle of the other side facade of the outline window frame, and two mounting slots are opened at the top of this side facade. A second traction disc is installed in each of the two mounting slots. The axis of the first traction disc is along the vertical direction, the axis of the second traction disc is along the front-back direction, and the axis of the third traction disc is along the left-right direction. The two ends of the traction rope are respectively wound around the first traction disc and the third traction disc.

The collars are fitted onto the internal sliding rod. A connecting block is fixed to the part of the traction rope between the first traction disc and one of the second traction discs. Another connecting block is fixed to the part of the traction disc between the first traction disc and the other second traction disc. The two connecting blocks are respectively fixed to one of the collars on the two folding shielding assemblies. The traction rope drives the two connecting blocks to move in the same direction, thereby folding or unfolding the two folding shielding assemblies in a synchronized manner.

[0027] The folding shielding assembly includes multiple vertically spaced transition strips, with a splicing strip between each pair of adjacent transition strips. The splicing strip is hinged to the transition strip, and a connecting rod is connected to the upper end of some transition strips.

An internal sliding rod 13 is installed at the top of the inner side of the profile window frame 11, and a folding shielding component 14 is provided at the lower end of the internal sliding rod 13. The folding shielding component 14 matches the inner side of the profile window frame 11 and the internal slot 4. The window includes a folding windproof window 1 and an external filter window 2. The opening and closing of the folding windproof window 1 is controlled by a two-way folding mechanism. The adjustment of the window is completed from the inside, which avoids the restriction of the ship's space caused by the internal window opening and also prevents the window from being affected by strong winds by the external window opening.

[0030] The external filter window uses commercially available filter windows, which mainly consist of the window body and the dustproof screen, filter cotton mesh, air filter paper, etc. installed in the window body for air filtration.

[0031] Combination Figures 2-5 The adjustment assembly 15 includes a first traction disc 151 mounted on the upper surface of the extension connecting plate 12 and a second traction disc 152 disposed inside the mounting groove 16. Two sets of the second traction disc 152 are provided. The second traction disc 152 is used for steering. A third traction disc 153 is installed at the middle of the side facade of the outline window frame 11. The surfaces of the first traction disc 151, the two sets of second traction discs 152 and the third traction disc 153 are wrapped with traction ropes 155. The surface of the third traction disc 153 is provided with a control handle 154, which is used to control the rotation of the third traction disc 153.

[0032] The connecting block refers to the L-shaped fixing hook 156 between the first traction disc 151 and the second traction disc 152. Two L-shaped fixing hooks 156 are provided, with their positions opposite each other, and one end of each L-shaped fixing hook 156 is fixedly sleeved on the surface of the traction rope 155. In other embodiments, the structure of the connecting block is not limited to this.

[0033] In this embodiment, each folding shielding component 14 includes a connecting bar 141 and a transition plate 142 installed at one end of the connecting bar 141. In this embodiment, there are three connecting bars 141. The other end of the three connecting bars 141 is equipped with a connecting block 144. The side surface of the transition plate 142 is provided with a splicing plate 143. The height of the splicing plate 143 matches the inner height of the built-in open slot 4. The transition plate 142 is provided between two adjacent splicing plates 143. The side surface of the transition plate 142 and the side end of the splicing plate 143 are connected by a hinge, a pivot, etc. The upper surface of the connecting block 144 is provided with a collar 145. The collar 145 is movably sleeved on the surface of the built-in slide rod 13. The connecting bar 141 and the transition bar 142 on each folding shielding assembly that are furthest from another folding shielding assembly are fixedly connected to the inner sidewall of the outline window frame 11, and the upper surface of the collar 145 on each folding shielding assembly that is closest to another folding shielding assembly is connected to the bottom surface of the corresponding L-shaped fixing hook 156.

[0034] In this embodiment, based on actual needs, the living quarters and living areas of the passenger and cargo ship are ventilated at least three times a day, for 20-30 minutes each time. Whenever ventilation is needed, the third traction disc 153 is rotated by turning the control handle 154. The traction rope 155 moves along the first traction disc 151 and the traction rope 155. Due to the opposite forces, the two L-shaped fixing hooks 156 gradually separate. The side ends of the splicing strip 143 become movable due to the hinges, and the splicing strip 143 folds around the connecting strip 142 as the axis. In the initial state, the two L-shaped fixing hooks 156 are close together, and the edges of the two splicing strips 143 in the middle of the ventilation opening are connected, and the window is closed. When the window is opened, due to the traction force of the two L-shaped fixing hooks 156, the two splicing strips 143 in the middle gradually separate, and the adjacent splicing strips 143 fold together, opening from the middle to both sides. On the one hand, natural ventilation is achieved through the external filter window 2, avoiding the high-speed navigation process and ensuring basic air intake needs. On the other hand, many impurities will remain on the surface of the external filter window 2 during use. The folding shielding component facilitates cleaning of the external filter window. This air intake method is suitable for passenger and cargo ships, is easy to operate, and effectively utilizes natural resources.
