Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is applicable to various changes in water flow conditions, from basic stages to highly difficult stages.
This invention relates to an artificial waterway for leisure, which is a leisure facility for enjoying canoes, kayaks, boats, etc.

(Prior Art) Conventionally, there have been leisure facilities that utilize natural rivers, lakes, and the like to enjoy water sports such as canoeing and boating. In addition, various leisure facilities are being considered in which large ring-shaped waterways (canals) are artificially formed and water is circulated and enjoyed.

(Problem to be solved by the invention) However, suitable natural rivers, lakes, etc. are often located in remote areas, and it takes valuable time and money to travel back and forth to the site and transport equipment. It was often inconvenient to use. In addition, although conventional artificial waterways are installed in areas with convenient transportation and are convenient to use, they have the disadvantage that the waterways change relatively little and are easy to get tired of.

In view of the above-mentioned points, the present invention effectively solves the problems of the prior art and provides an artificial waterway for leisure use that can be provided with various complicated water flow changes from basic stages to highly difficult stages. With the goal.

(Means for Solving the Problems) In order to achieve such an object, the present invention has the following features:
In an artificial waterway having a water supply pump that circulates and distributes water in a long-distance waterway, the artificial waterway is formed of a waterproof flexible material, and pressure is applied to the artificial waterway from the outside provided in the artificial waterway. a shape variable means that changes its cross-sectional shape to generate a water flow change due to a narrow waterway or shallow water, a fountain nozzle installed in the artificial waterway that generates a water flow change due to a fountain, the water supply pump, the shape variable means, and the fountain nozzle. It is characterized by comprising a calculation control device that sets required conditions and temporal changes and performs program control.

(Function) By using such technical means, the present invention enables a long-distance waterway to be made of waterproof and flexible material, and in this embodiment, a hydraulic cylinder and a fountain nozzle are provided at any location of the artificial waterway as shape variable means. The calculation control device sets the required conditions, namely, the water supply amount of the water supply pump, the pressing force of the hydraulic cylinder, the pressing angle, the opening degree of the fountain nozzle, the injection direction, and further changes over time, and performs program control. As a result, water flow changes such as narrow channels, shallow waters, eddies, rapids, or underground flows can easily occur.

(Example) Next, an example of the present invention will be described in detail based on the drawings.

A, the fountain nozzle 6 and the calculation control device 7 (second
(Figure). 4A and 8 are a submersible pump and a canoe. The annular waterway 1 is formed in a U-shape, is made of waterproof flexible organic material, and is configured in the shape of a large horizontal ring. A part of the annular waterway 1 has starting and ending waterways 2 and 3, which are the starting and ending points.
is installed integrally. Furthermore, the circular waterway 1,
The starting and ending waterways 2 and 3 are annular grooves 1A made of wood, vinyl panels, concrete, etc.
It is housed inside, reinforced and protected. The reservoir 9 is disposed in the inner space of the annular waterway 1, and stores the return water that overflows from the drain port 9A provided in the annular waterway 1. The water is circulated and supplied to the annular waterway 1 by the water supply pump 4 via the purification device 9B. Ru.

The narrowing hydraulic cylinders 5 are installed in the annular waterway 1 at appropriate intervals, and apply a pressing force to the side surface of the annular waterway 1 from the outside to form a valley-like narrow part and increase the water flow velocity in this part. Further, the hydraulic cylinders 5A for shallow water are similarly installed at appropriate intervals in the ring-shaped waterway 1, and apply a pressing force to the bottom surface from the outside to form a shallow water portion and change the water flow velocity in this portion. Note that the pressing force and pressing direction of the hydraulic cylinders 5 and 5A are set appropriately, and the side and bottom surfaces of the annular waterway 1 that receive this pressing force are sufficiently reinforced with a reinforcing material.

The fountain nozzles 6 are arranged at appropriate intervals in the annular waterway 1 and eject water supplied from the water supply pump 4 to create a water stream. Furthermore, by making the installation angle and opening degree of the fountain nozzle 6 variable, eddies, turbulence, underflow, etc. are generated and changed in the water flow. Note that the attachment location of the fountain nozzle 6 is sufficiently reinforced with a reinforcing material.

As shown in FIG. 2, the calculation control device 7 mainly consists of an input section 10, a CPU 11, a memory section 12, and an I/O interface section 13, and controls the water supply amount of the water supply pump 4, which is a hardware section, and the hydraulic pressure for narrow spaces. Setting a program to set the pressing force and pressing angle of the cylinder 5 and the shallow water hydraulic cylinder 5A, and the installation angle and opening degree of the fountain nozzle 6,
This program is sent to the memory section 1 through the input section 10.
Load it into 2. By changing various setting values and controlling various programs from basic to highly difficult stages, it is possible to create a variety of conditions simulating narrow channels, shallow water, whirlpools, rapids, or underground currents.

Therefore, by specifying an arbitrary program on the keyboard of the input section 10, the CPU 11 reads the program from the memory section 12, and various conditions of the annular waterway 1 are set. This program allows you to change the set values over time, and as you go around the annular waterway 1 not only once, but twice or three times, you can change the setting conditions in a variety of ways. You can enjoy the long waterway as a rich leisure facility.

In addition, when a contestant capsizes from the canoe 8, the calculation control device 7 issues a command to stop the water supply pump 4 and quickly remove water using a detector (not shown) installed on the bottom surface. The annular waterway 1 is shallow, easy to stand up, and safe.

In this way, the present invention provides a game-like experience where you can enjoy various programs from the basic stage to the highly difficult stage, and enjoy the comfortable thrill of overcoming and conquering difficult courses and recording time. Feelings are satisfied. In addition, in this waterway 1, television cameras (not shown) installed appropriately above and on the side windows of the waterway 1 are used for intensive monitoring to observe the water flow condition and confirm safety, and to provide guidance to the competitors. Further, normally, horizontal circulation waterway 100
