Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an air flow rectification structure for an atrium-type bridge for preventing smoke pollution on ships.

[Conventional technology]

The stern deck room is as shown in the side view of Figure 4.
It has a structure in which the wheelhouse 2 is stacked directly above the crew quarters 1 on the stern deck, but with the recent increase in the size of ships, the viewing angle θ from the wheelhouse 2 to the ship is becoming smaller. In order to ensure ship handling performance, superstructures are gradually becoming taller, and as the height increases, the superstructures become heavier, vibrations increase, the height of chimneys increases, and piping, wiring, and interior fittings in living quarters become heavier. This has led to increased complexity, increased construction materials, increased maintenance costs,
Not only has construction cost soared, but livability has declined.

Therefore, in order to solve these problems,
As shown in the side view in Figure 5 and the front view in Figure 6, only things related to the living quarters are put together in the deckhouse 1.
A pillar 4 is installed on top of the pillar 4, and only the things necessary for maneuvering the ship are assembled into the wheelhouse 2 at the top of the pillar 4. An elevator, stairs, etc. are installed in the pillar 4 as a means of transportation between the deckhouse 1 and the wheelhouse 2. Such a structure has many advantages such as improved ship handling performance, simplification of the superstructure and internal fittings, vibration prevention, and reduced chimney height, and improves livability. Due to the windsock effect of the airflow below the wheelhouse 2, the height of the outlet 6 of the rear chimney can be placed within the turbulence zone, thereby making it possible to reduce the height of the chimney.

However, in such a structure, it is difficult to install elevators, stairs, etc. that serve as a communication route to the deckhouse 1 living quarters within the pillars 4 that support the wheelhouse 2. It is relatively easy if there is space in the direction, but
In a normal ship, it is practically difficult to install such a lifting equipment on the prop 4, and if it is installed, the prop 4 itself becomes large, and if the prop 4 becomes large, the windsock effect of the air current will be halved. At the bottom of the wheelhouse 2, there is a stairwell that serves as a traffic route with the deckhouse 1, or for the installation of pipes, ducts, and electric wires, as shown in the side view in Figure 7.
As shown in the plan view in Figure 8 and the front view in Figure 9, a small deckhouse 5 and a large support are required, and the small deckhouse 5 and large support block the airflow from the front, so Figures 7 and 8 As shown by the broken line arrow in , this will impede the smooth outflow of exhaust gas from the chimney and cause smoke damage.

[Problem that the invention attempts to solve]

The present invention was proposed in view of the above circumstances, and its purpose is to provide an air flow rectification structure for an atrium type bridge that prevents smoke damage by smoothing the outflow of exhaust gas from a chimney.

[Means for solving problems]

To this end, the present invention is designed to provide a gap between the upper surface of the accommodation compartment provided on the bridge deck and the upper surface of the accommodation compartment to allow the outside air to pass through, and to provide a space between the front pillars of the pair of left and right pillars and the small space in the center of the rear. In an atrium-type bridge structure with a wheelhouse supported at three points via a deckhouse, these are installed on the bridge decks at the rear and rear sides of the left and right ends of the small deckhouse, respectively, and each slopes in the longitudinal direction of the ship. Accordingly, the ship is characterized by being equipped with an outside airflow introduction baffle plate that introduces outside airflow in the direction of the centerline of the bridge.

[Effect]

With such a configuration, it is possible to obtain an airflow rectification structure for an atrium-type bridge that allows exhaust gas to smoothly flow out from the chimney and prevents smoke damage.

〔Example〕

An embodiment of the present invention will be explained with reference to the drawings.
FIG. 1 is a side view showing the upper part of the bridge structure, FIG. 2 is a plan view of FIG. 1, and FIG. 3 is a partially enlarged perspective view showing the rectifier plate of FIG. 1.

In the above figure, the same symbols as in Figs. 4 to 9 indicate the same members as in Figs. They are each established on the bridge deck 3 on the aft side of each end, and their horizontal cross section curves concavely toward the small deckhouse 5, and their height reaches the level of the lower part of the wheelhouse 2. .

Reference numeral 9 denotes a bracket that fixes the lower end of the aggregate 10 of the rectifier plate 8 to the bridge deck 3, and the plate material stretched over the aggregate 10 may be a vinyl plate or canvas instead of a steel plate.

In such a structure, as shown by the broken line arrow in FIG. After flowing through the gap, it flows towards the stern along the left and right ends of the chimney and then flows away.

Due to the flow diagonally to the rear of the ship caused by this rectifier plate 8, the stagnation of the airflow that occurs behind the pillars and small deckhouse shown in Figure 8 is blown away toward the stern, preventing smoke damage caused by exhaust gas from the chimney. To prevent.

[Effect of idea]

In short, according to the present invention, there is an interval between the upper surface of the accommodation section provided on the bridge deck and the upper surface of the accommodation section that allows the outside air to flow through, and between the left and right pair of front columns and the rear center In the atrium type bridge structure with a wheelhouse supported at three points via a small deckhouse,
Each of these plates is installed on the bridge deck on the aft side of the left and right ends of the small deckhouse, and is equipped with rectifier plates for introducing outside airflow that are tilted relative to the longitudinal direction of the hull to introduce outside airflow toward the centerline of the bridge. As a result, the present invention is extremely useful industrially because it provides an air flow rectification structure for an open-air bridge that smooths the outflow of exhaust gas from the chimney and prevents smoke damage.
