Description

TECHNICAL FIELD

[0001] The utility model belongs to ship design technical field, concretely relates to a ship air guide device. BACKGROUND

[0002] At present, most of the ship chimneys are arranged adjacent to the residential area, and the chimney exhaust gas smoke drifts to the residential area with the wind, which affects the environment of the crew residential area. It not only affects the living area crew living comfort, but also pollutes the residential area top deck (compass deck) with exhaust gas particles, increasing the crew cleaning workload. SUMMARY

[0003] In order to solve the technical problems existing in the prior art, the utility model provides a ship air guide device, which comprises an arc-shaped ceiling, the air guide device is close to the front end of the compass deck, is arranged along the front inclined wall of the cab, is combined into a horn-shaped structure, the airflow passage area of the horn mouth changes, the inlet flow is greater than the outlet, and the outlet forms a relatively high-speed airflow.

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

[0005] Further, the arc-shaped ceiling is a structure symmetrical on the left and right sides with respect to the center axis.

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

[0007] Further, the angle of the front end of the air guide structure frame is 75° to 35°.

[0008] Further, a plurality of support elbow plates are vertically arranged below the arc-shaped ceiling.

[0009] Further, the support elbow plates are arranged in alignment with the vertical structure.

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

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] The utility model can collect and change the wind direction and wind speed, reduce the situation that the chimney exhaust gas drifts to the residential area, and improve the comfort of the crew residential area environment. BRIEF DESCRIPTION OF DRAWINGS

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

[0018] The ship air guiding device provided by this utility model includes an air guiding structure installed on the compass deck atop the residential area. The air guiding structure is made of steel plate and consists of an arc-shaped canopy and supporting elbow plates, which are aligned with the main support structure. The air guiding structure is located near the front end of the compass deck and arranged along the forward sloping wall of the bridge, forming a "trumpet" shape. Through the change in the airflow channel area at the trumpet opening, the inlet airflow is greater than the outlet airflow, creating a relatively high-speed airflow at the outlet. The air guiding structure layout diagram is shown below. Figure 1 As shown.

[0019] Reference Figures 2-4 The specific structural design of this application:

[0020] The side panels and roof form the air-guiding structure frame. The front end of the frame extends along the front sloping wall, with the angle transitioning from 75° to 35°, also serving as a rain and sun awning for the cab windows, improving visibility. The curved design of the roof reduces drag and is aesthetically pleasing.

[0021] A support elbow plate is installed in the corresponding positive section for reinforcement;

[0022] The side panels and ceiling have been reinforced with ribs.

[0023] The entire air guide structure is funnel-shaped, wider at the front and narrower at the back. When the ship is sailing at low speed, it can direct the wind to the area that needs to be purged, preventing chimney exhaust from drifting onto the deck of the residential area.

[0024] In summary, this is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification are within the scope of the present utility model patent.
