Description

Technical Field

[0001] This invention relates to the field of marine technology, specifically to an air-blocking device and a plug door for a curved deck sliding door in a ship's clean area. Background Technology

[0002] With increasing medical needs on board ships, some medical compartments require the establishment of stable pressure gradients. Many compartments on ships with medical functions are equipped with sliding doors to create pressure gradients. In existing technology, rubber strips are bonded to the bottom of the sliding door panels to achieve a sealing and air-blocking function. However, when establishing a pressure gradient, the sealing rubber at the bottom of the current marine sliding door cannot adapt to the arches and ridges of the ship's deck, and the distance between the rubber strip and the deck surface is difficult to control, making it very difficult to establish a stable pressure gradient, resulting in significant challenges in on-site construction and commissioning. Furthermore, the rubber strips may rub against the deck surface during door use, causing the deck surface to darken and become difficult to clean. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides an air-blocking device for a curved deck sliding door in a ship's clean area and a plug door. As a negative pressure air-blocking structure, it is applied to a ship's plug door to improve the sealing performance of the bottom sealing strip of the ship's plug door and reduce the difficulty of establishing a stable pressure gradient. At the same time, it can be adapted to the beam arch and ridge arc shape of the ship's deck, and there is no friction with the deck surface during use.

[0004] The objective of this invention is achieved through the following technical solution: an air-blocking device for a curved deck sliding door in a ship's clean area, comprising:

[0005] The guide rod has a moving mechanism at its bottom that contacts the deck surface and is connected to the sliding door panel at its top. The upper end of the guide rod has a steering mechanism that can drive the guide rod to rotate.

[0006] A rubber strip is installed at the other end where the guide rod connects to the sliding door panel, and the rubber strip has a certain length.

[0007] Preferably, the moving mechanism includes at least a small wheel and a slider.

[0008] Preferably, the steering mechanism includes at least a pivot shaft connected to the upper part of the guide rod.

[0009] Preferably, a connecting rod is provided in the middle of the guide rod, and the connecting rod is fixedly connected to the rubber belt.

[0010] Preferably, a decorative cover is provided between the air-blocking device and the sliding door.

[0011] Preferably, the decorative cover has a rotating shaft groove inside.

[0012] In addition to providing an air-blocking device for a curved deck sliding door in a clean area of ​​a ship, the present invention further provides a marine plug door, on which the aforementioned air-blocking device is provided.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This invention provides an air-blocking device and a plug door for a curved deck sliding door in a ship's clean area. As a negative pressure air-blocking structure, it is applied to marine plug doors to improve the sealing performance of the bottom sealing strip of the marine plug door and reduce the difficulty of establishing a stable pressure gradient. At the same time, it can be adapted to the beam arch and ridge arc shape of the ship's deck, and there is no friction with the deck surface during use.

[0015] The air-blocking device provided by this invention allows the rubber strip to respond to the rise / fall of the deck surface, ensuring that the gap between the rubber strip and the deck remains essentially constant. This reduces the difficulty of establishing a stable pressure gradient and simplifies construction and commissioning. The air-blocking device avoids friction with the deck surface during movement, and the addition of a decorative cover to conceal the main body of the rubber strip improves aesthetics.

[0016] This invention reduces the difficulty of establishing a stable pressure gradient in medical compartments, reduces commissioning time, shortens product manufacturing cycle, saves product costs, and enhances the reliability and stability of the pressure gradient. Attached Figure Description

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0024] The present invention provides an air-blocking device for a curved deck sliding door in a ship's clean area, comprising:

[0025] Guide rod 1, with a moving mechanism at the bottom of the guide rod 1, which contacts the deck surface 2 and is connected to the sliding door panel 3 at the top. A steering mechanism is provided at the upper end of the guide rod 1, which can drive the guide rod 1 to rotate.

[0026] Rubber strip 4 is set at the other end where the guide rod 1 connects to the sliding door panel 3, and rubber strip 4 has a certain length.

[0027] In one embodiment of the present invention, the moving mechanism includes at least a small wheel 5 and a slider. When the moving mechanism is a small wheel 5, the deck surface 2 does not need to be structurally modified. When the moving mechanism uses a slider, a suitable guide rail mechanism needs to be configured on the deck surface 2 so that the moving mechanism can move back and forth on the deck surface 2.

[0028] In one embodiment of the present invention, the steering mechanism includes at least a rotating shaft 6 connected to the upper part of the guide rod 1. When the motion mechanism passes through the beam arch or ridge arc 10, it will drive the guide rod 1 to move up and down. By setting the rotating shaft 6, during the up and down movement of the guide rod 1, the guide rod 1 will be driven to rotate, and further drive the rubber strip 4 connected to the guide rod 1 to move up and down, always maintaining the same height as the deck surface 1.

[0029] In one specific embodiment of the present invention, an air-blocking device for a curved deck sliding door in a ship's clean area is provided, such as... Figures 1 to 2 As shown, multiple air-blocking devices are installed below the sliding door panel 3, and their movement direction is as follows: Figure 2 As indicated by the middle arrow. In this embodiment, the specific structure of the gas-blocking device is as follows: Figure 3 As shown, the system includes: a guide rod 1, a rubber strip 4, a small wheel 5, a rotating shaft 6, a connecting rod 7, a decorative cover 8, and a wheel axle 11. The connecting rod 7 is located in the middle of the guide rod and is fixedly connected to the rubber strip 4. The guide rod 1 is connected to the small wheel 5 via the wheel axle 11. In this embodiment, when the ship's sliding door opens and closes, it drives the movement of the small wheel 5. The small wheel 5 rises and falls with the arch or ridge 10 of the deck surface 2, causing the guide rod 1 to rise and fall, while simultaneously being forced to rotate. The movement of the guide rod 1 causes the rubber strip 4 to rise, fall, and rotate, fitting the arch and profile of the ship's deck. This ensures that the gap distance between the sealing rubber strip 4 and the deck surface 2 remains constant, reducing the difficulty of establishing a stable pressure gradient. In this embodiment, an air-blocking device allows the rubber strip 4 to respond to the rise / fall of the deck surface, generating corresponding movement and rotation.

[0030] like Figures 4 to 5 As shown, in one embodiment of the present invention, a decorative cover 8 is provided between the air-blocking device and the sliding door. A pivot groove 9 is provided inside the decorative cover 8. In this embodiment, by adding the decorative cover 8, the rubber strip 4 is covered, protecting the rubber strip 4 while improving the overall aesthetics.

[0031] like Figure 5 As shown, as a further optimization of the above embodiment, the height of the rubber strip 4 from the deck surface 2 needs to be maintained at a height of L, and the value of L is adjusted according to the requirements for establishing the negative pressure gradient.

[0032] In addition to providing an air-blocking device for a curved deck sliding door in a clean area of ​​a ship, the present invention further provides a marine plug door, on which the aforementioned air-blocking device is provided.

[0033] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
