Abstract

PURPOSE:To obtain an easy training equipment for a canoe without using a natural river by providing a continuous change in gradient, water depth and width for a water channel, arranging a float, which is assembled to rock, as a dummy obstacle in an arbitrary position, locking the obstacle to the bottom or wall of the water channel by a chain or a rope and constituting an artificial stream. CONSTITUTION:On a side wall 2, several plural jet nozzles 5 are provided longitudinally from a bottom 3 to an water surface and further unevenness is attached to the bottom 3 as well to generate a change in an water current. The unevenness of the bottom 3 disorders the flow of the water surface and changes the cross-section area of a water channel 4 and the flow of water is complicated and changed. In the middle of the water channel 4, an obstacle 7, which is constituted to be rock-shaped by rubber or urethane foam, is locked to the bottom 3 by a chain 8. This obstacle 7 is equipped with the depth to sink under the water surface by changing the length of the chain 8 or locked to the side wall 2 and bottom 3 and fixed not to be moved according to a case. The interval of the side wall 2 is equipped with a change like a second figure so as to generate the natural change in the speed of flowing water. When the training equipment is used, the change is provided in the conduit 4 to operate the canoe by changing the flowing speed of each jet nozzle 5 or changing the position of the obstacle 7.

Description

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

(Prior Technology) Conventional canoe training facilities have consisted of ropes, nets, etc. stretched over 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: Conventional practice ranges not only give consideration to river managers;
Because rivers are public entities, setting up ropes and nets is done without consideration for people other than canoeists.
Going to practice was also limited due to traffic and time constraints, and of course the practice location, practice period, and practice time were also 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 Problems) In order to achieve the above object, a canoe training facility according to the present invention forms a water channel having a depth and width sufficient for rowing a canoe, and Jet nozzles that spray water, air, etc. into the water in the direction of flow of water filled with water are placed on the bottom and walls of the waterway, and the waterway has continuous changes 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.

(Function) As a result of changing the steepness, width, and depth of the slope, 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. .

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a part of an artificial mountain stream 1, in which a side wall 2 and a 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 toward 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, the inclination angle of the bottom 3 includes not only a change in the slope of the channel 4 itself, but also a change in the direction of the channel as well as from the end of the channel toward the center or from the center to the end.

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

In the middle of the channel 4, an obstacle 7 made of rubber or foamed urethane and configured in the shape of a platform is secured to the bottom 3 with 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. It has the effect of creating an artificial mountain stream that resembles a natural mountain stream by changing the state and flow of water.

In addition, you can select and operate the jet nozzle's jet speed and operating position, and change the locking position of obstacles.
It has the effect of adding variety to slalom practice, allowing you to practice with various paddle operations in a nearby location.
