Description

[Detailed description of the invention] (a) Field of the invention This invention relates to a drainage system for a ship, and more specifically, to a drainage system for a ship that drains water accumulated in a small ship such as a boat.

(b) Background of the invention Generally, devices used for draining water from ships use power from electric power or an internal combustion engine to operate a pump to drain water accumulated at the bottom of the ship. The ships were virtually never equipped with any equipment requiring power such as those described above.

(c) Purpose of the invention Therefore, the purpose of this invention is to provide a drainage device for a ship that can drain water by utilizing the rolling or pitching of the ship without requiring power.

(d) Summary of the invention This invention consists of a drainage mechanism in which a waterway is continuous in a zigzag pattern in the vertical direction, and the folded part is formed into a water reservoir, which is swingably supported on the bottom of the ship. A drainage device for a ship is characterized in that a part of the drainage mechanism spaced apart by a predetermined distance is connected to a weight side hanging down from a part of the ship.

(E) Effect of the invention This invention utilizes the shaking of the ship to swing a hanging weight, and the swinging of this weight swings the drainage mechanism to drain water accumulated at the bottom of the ship through a waterway. The water is guided through the vessel to a water reservoir, and the rocking of the ship sequentially guides it to the upper water reservoir, where it is discharged overboard through a waterway at the top.

In this way, water can be drained naturally without the need for power, and the structure is simple and can be made compact, making it ideal for draining water from small vessels such as boats.

(f) Example of the invention An example of the invention will be described below in detail based on the drawings.

The drawing shows the ship's drainage system, and in Figure 1:
Reference numeral 1 denotes a boat, 2 a bottom portion of the boat, and 3 a drainage mechanism. The drainage mechanism 3 has a central portion supported swingably toward the boat by a shaft 3a.

This drainage mechanism 3 has a side wall 4 as shown in FIG.
The water channels 5 are arranged in a zigzag pattern in the vertical direction.

Reference numerals 6, 6 denote semi-cylindrical connecting bodies provided in the zigzag-shaped folded portions, and these connecting bodies 6, 6 connect the water channels 5.

The turning part of the water channel 5 is formed into a water reservoir part 8 by a step 7, and this step 7 prevents the accumulated water from flowing backward (downward).
is being prevented.

Further, on the side of the drainage mechanism 3, an arm 10 having a weight 9 attached thereto is suspended by a shaft 11 so as to be swingable towards the boat side.

The above arm 10 and a part of the drainage mechanism 3 are connected by a rod 12.

With this structure, the rolling of the boat 1 causes the weight 9 to also swing, and the swinging of the weight 9 causes the drainage mechanism 3 to swing around the shaft 3a via the rod 12, thereby causing the boat bottom 2 to swing. The collected water is led to the lowermost water reservoir 8-1 through the lowermost water channel 5-1, and then is rolled in the opposite direction through the water channel 5-2 to the water reservoir 8-2. In this way, the water is guided to the upper water reservoir 8 one after another with each rolling, and the water accumulated in the uppermost water reservoir 8-n is transferred to the ship by the uppermost waterway 5-n. If the amount of water stored in the bottom part 2 is large, it is continuously led to the water storage part 8 one after another, and is discharged overboard every time the water is rolled.

(g) Other examples of the invention The one shown in Figs. 3 and 4 has a weight 9a suspended next to the drainage mechanism 3, and a protruding rod 12a is integrally attached to the hanging arm 10a of this weight 9a. This protruding rod 12a causes the drainage mechanism 3 to
The other points are the same as those of the above-mentioned embodiment, and therefore will not be described here.

Although these embodiments have described drainage by rolling, this is because the drainage mechanism 3 is arranged in the width direction of the boat 1, and by arranging this drainage mechanism in the length direction, pitting drainage can be achieved. can be done.

Claims (1)

[Scope of Claim for Utility Model Registration] A drainage mechanism in which a waterway is continuous in a zigzag shape in the vertical direction and the folded part is formed into a water reservoir is pivotally fixed to the bottom of a ship, and a predetermined position from this pivot support is provided. A drainage system for a ship, characterized in that a part of the drainage mechanism that is spaced apart and a weight side that hangs down from a part of the ship are connected directly or indirectly.
