Description

DETAILED DESCRIPTION OF THE INVENTION <<Industrial Application Field>> The present invention relates to a canoe training facility that is capable of slalom and the like.

≪Prior Technology≫ Traditional canoe training facilities consisted of stringing ropes, nets, etc. in natural mountain streams and rivers. This provided a partial practice range in a certain area, such as a river.

≪Problem to be solved by the invention≫ Description In the conventional practice range, not only consideration is given to river administrators, but also because the river is a public entity, people other than Karoo practitioners are required to set ropes and nets. In addition to lack of consideration for the situation, the ability to go to practice was limited due to traffic and time constraints, and not only practice locations but also practice times and practice hours were limited.

The present invention has been made in view of the above circumstances, and its purpose is to provide a convenient canoe training facility that does not require the use of natural rivers.

<<Means for Solving the Problem>> In order to achieve the above object, the canoe training facility according to the present invention forms a water channel having a depth and width sufficient for rowing a canoe; A jet nozzle is placed on the bottom and wall of the waterway that directs water, air, etc. in the direction of flow of the water filled with water and sprays water, air, etc. into the water, and the waterway has a continuous change in gradient, water depth, and width. At the same time, floats resembling rocks are placed at arbitrary positions as pseudo obstacles.
This obstacle is anchored to the bottom or wall of the channel with chains or ropes to create an artificial mountain stream, and canoes are floated on this stream for practice.

<<Effect>> As a result of changing the slope, width, and depth, the speed and direction of water flowing in the channel change.

In addition, the jet speed of the jet nozzle is changed to intentionally change the water flow in an unnatural direction, or the natural speed of the water flow in the flow path is changed. This is influenced by the depth and size of obstacles in the waterway, and the number, size, and position of obstacles can be changed according to the preference and skill of the canoeist, and the jet speed of the jet nozzle can be adjusted accordingly. change.

<<Example>> Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

Figure 1 shows a part of an artificial mountain stream 1, with side walls 2
and the bottom 3 form a water flow path 4, and a water jet nozzle 5 is installed on the side wall 2 and the bottom 3.

A plurality of jet nozzles 5 on the side wall 2 are provided vertically from the bottom 3 to the water surface, and the bottom 3 is also undulated to vary the water flow.

The undulations of the bottom 3 make the flow of water rough, and the cross-sectional area of the channel 4 changes, causing the flow of water to change in a complicated manner.

Furthermore, not only the gradient change of the channel 4 itself, but also
The inclination angle of the bottom 3 includes not only the flow path direction but also a change from the end of the flow path toward the center or from the center to the end.

The water jet nozzle 5 supplies the water in the channel 4 to a centrifugal pump or the like, or supplies the circulating water to a centrifugal pump or the like, and connects the discharged pressurized water to the water conduit 6, and connects the injection nozzle at the tip to the side wall 2, It is constructed by being buried and fixed in the bottom 3.

In the middle of the flow path 4, an obstacle 7 made of rubber or foamed urethane is fixed to the bottom 3 by a chain 8.
The length of the chain 8 of this obstacle 7 is changed to the depth at which it sinks below the water surface, or in some cases, it is fixed to the side wall 2 and the bottom 3 so that it does not move. The locking position of the obstacle 7 can be easily changed by removing the chain 8.

The spacing between the side walls 2 is varied as shown in FIG. 2 to produce a natural change in the speed of flowing water.

In use, the flow rate of each water jet nozzle 5 is changed and the position of the obstacle 7 is changed to bring about changes in the flow path 4 through which the canoe is operated.

In this manner, the state of the artificial mountain stream 1 is made variable, and various changes are made to the paddle operation.

<<Effects>> As explained in detail above, the canoe training facility of the present invention forms a water flow path, which itself has a gradual slope and changes in water depth and width. This has the effect of creating an artificial mountain stream that is similar to a natural mountain stream by changing the state and flow of the mountain stream.

In addition, it is possible to select and operate the jet nozzle's jet speed and operating position, and to change the locking position of obstacles, adding variety to slalom practice and allowing you to perform various paddle operations at hand. It has the effect of allowing you to practice.
