Abstract

[Problem] In a river dotted with rapids, shallow water, and rocky areas, it is possible to row with good rudder performance, no need for an empty rudder, and braking power, regardless of changes in the flow rate of the river or the number of passengers. The task is to provide downriver charters. [Means for Solving the Problems] A steering plate immersed in water, and a horizontally extending steering rod for operating the steering plate on the hull, include a first steering rod extending vertically on the outer surface of the rear end of the hull. The first shaft is connected by a shaft, and the first shaft is rotatable left and right about the center of the first shaft, and vertically movable about the center of the second shaft in the horizontal direction. This is a configuration of a downstream charter boat equipped with at least one rudder mechanism attached to the outer surface of the end.

Description

The present invention relates to a river boat chartered to go down the river without an empty rudder and equipped with a rudder mechanism that ensures safety while going down the river.

River rafting is a thrilling experience for tourists. River charter boats are operated by multiple experienced boatmen, and the conditions change depending on the number of people on board and daily fluctuations in water flow. In addition, there are many places with rapids, and there are places with protruding rocks, which are dangerous, and the steering method is difficult, leading to human errors such as dry rudder, which has resulted in fatal accidents. The cause of the accident was the steering method of the downriver charter boat , which needs to be improved.

To solve this problem, Patent Document 1 discloses an actuating plate in which a rotating shaft bent in an L shape is attached to the tip of a rowing rod, and a propulsion plate is rotatably attached to the horizontal axis of this rotating shaft. The compact device is characterized in that the actuating plate is provided with a pair of pushers protruding from the actuating plate, which are opened in a bifurcated manner on both the left and right sides of the propelling plate, with the mounting portion of the propelling plate serving as a crotch portion. It is a human-powered propulsion device for ships. The problem is that because the propulsion plate rotates, the forward direction is unstable, making it unsuitable for descending shallow waters or rapids with protruding rocks.

FIG. 5(a) shows a horizontal blade (6) according to the third invention in which one horizontal blade (6) is provided on both sides of the rudder plate (3) of one rudder mechanism (5). FIG. 2 is a perspective view of the embodiment. When the steering rod (4) is approximately horizontal, the horizontal blade (6) is also horizontal, and the bottom of the rudder plate (3) is horizontal at the same height as the bottom of the hull (16), so the horizontal blade (6) The rudder plate (3) is stable without water resistance. FIG. 5(b) shows horizontal wings (6) of the third invention shown by 12 diagonal lines, two on each side of the rudder plates (3) of three rudder mechanisms (5). FIG. 2 is a perspective view of an embodiment showing that a

Figure 5(c) shows that when the helmsman lowers the steering rod (4), as the water flows over the upper surface of the horizontal blade (6) as shown by the arrow, a force is generated to push down the horizontal blade (6). A downward force acts on the hull (16) to brake the speed of the river boat . In Figure 5(d), when the helmsman raises the steering rod (4) upward, the flowing water generates a force pushing up the lower surface of the horizontal wing (6) as shown by the arrow, and the hull (16) rises upward. The force acts to brake the speed of the charter boat down the river . Therefore, by moving the steering rod (4) of the rudder mechanism (5) up and down quickly or by increasing the frequency, the speed of flow can be controlled by braking. If you find yourself in a situation where you need to brake urgently in shallow water, you can forcefully raise the steering rod (4) and sink it into the sand at the riverbed to apply the brakes.
