The ship air guide device comprises an arc-shaped ceiling, an air guide structure is close to the front end of a compass deck, is arranged along the front inclined wall of a cab and is combined into a horn-shaped structure, the flow of an air inlet is larger than that of an air outlet through the change of the area of an airflow channel of a horn mouth, and the air outlet forms relatively high-speed airflow. The device can collect and change the wind direction and wind speed, reduce the situation that chimney waste gas floats to the residential area, and improve the comfort of the crew residential area environment.

Description

Technical Field

[0001] The present invention belongs to the technical field of ship design, and particularly relates to a ship air guiding device. Background Art

[0002] At present, most ship chimneys are arranged adjacent to the living area. There is a phenomenon that the exhaust gas from the chimney drifts towards the living area with the wind, which affects the environment of the crew's living area. It not only affects the living comfort of the crew in the living area, but also pollutes the top deck surface (compass deck) of the living area with exhaust gas particles, increasing the cleaning workload of the crew. Summary of the Invention

[0003] In order to solve the technical problems existing in the prior art, the present invention provides a ship air guiding device, including an arc-shaped ceiling. The air guiding structure is close to the front end of the compass deck and is arranged along the front inclined wall of the cab, combined into a horn-shaped structure. Through the change of the air flow channel area of the horn mouth, the air inlet flow rate is greater than the air outlet flow rate, and a relatively high-speed air flow is formed at the air outlet.

[0004] Further, the arc-shaped ceiling and the sealing plates on both sides of the arc-shaped ceiling form a framework of the air guiding structure. The front end of the air guiding structure framework extends along the front inclined wall and also serves as a rain and sunshade for the cab window.

[0005] Further, the arc-shaped ceiling has a structure that is symmetric about the central axis on both the left and right sides.

[0006] Further, the width of the part of the arc-shaped ceiling corresponding to the central axis is greater than the width of the symmetric parts on both sides.

[0007] Further, the angle at the front end of the air guiding structure framework transitions from 75° to 35°.

[0008] Further, a number of support gussets are vertically arranged below the arc-shaped ceiling.

[0009] Further, the support gussets are arranged aligned with the center structure.

[0010] Further, both the support gussets and the sealing plates are provided with reinforcing ribs.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] The present invention can collect and change the wind direction and speed, reduce the situation of chimney exhaust gas drifting towards the living area, and improve the comfort of the environment in the crew's living area. Brief Description of the Drawings

[0017] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] The ship air guiding device provided by the present invention is provided with an air guiding structure on the compass deck at the top of the residential area. The air guiding structure is made of steel plates and consists of an arc-shaped ceiling and supporting gussets. The supporting gussets are arranged aligned with the center structure. The air guiding structure is close to the front end of the compass deck and is arranged along the front inclined wall of the cab, forming a "horn-shaped" structure. Through the change of the air flow channel area of the horn mouth, the air inlet flow rate is greater than the air outlet flow rate, and a relatively high-speed air flow is formed at the air outlet. The layout diagram of the air guiding structure is as Figure 1 shown.

[0019] Referring to Figures 2-4 , the specific structural design of this application:

[0020] The two side sealing plates and the ceiling form the air guiding structure framework. The front end of the framework extends along the front inclined wall, and the angle transitions from 75° to 35°, which also serves as a rain and sunshade for the cab window, improving the visibility. The ceiling is designed in an arc shape, which can reduce a certain amount of resistance and is also beautiful;

[0021] In the middle, supporting gussets are provided at the corresponding center for strengthening;

[0022] The side sealing plates and the ceiling are provided with reinforcing ribs;

[0023] The entire air guiding structure is in a horn shape, larger at the front and smaller at the rear. When the ship is sailing at a low speed, the wind can also be guided to the area to be purged, preventing the chimney exhaust gas from floating towards the residential area deck.

[0024] In summary, this is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention. All equivalent changes and modifications made according to the scope of the present invention patent and the content of the specification are within the scope covered by the present invention patent.
