CONSTITUTION:On the bottom face 2 of a pool 1, luminous bodies 3 are provided in a matrix shape, grooves 4 being parallel to each other are formed along its longitudinal directions, and luminous body 3 groups of I-IV lines are fitted into each groove thereof 4, respectively. Also, the luminous body 3 emits a flat and sector-like laser light 7 toward the upper part by a voltage applied through a controller 6, and this light 7 can be confirmed visually. In this state, by allowing the light 7 from each luminous body 3 to function as a wall material, a labyrinth is formed in the water of the pool 1. Also, which luminous body is brought to light emission, and the direction of the light 7, and an angle opened to its sector shape can be selected variously by the controller 6. By utilizing such a labyrinth, orienteering can be enjoyed in the pool 1.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a light emitting device for guiding swimmers and ships to predetermined positions and for allowing them to confirm their own positions.

(Prior art and problems to be solved by the invention) (11 Swimming in a pool is relatively monotonous, so
BACKGROUND OF THE INVENTION Conventionally, devices have been provided that generate large circulating water flows or waves within a pool.

However, these days, when leisure activities are diversifying, these things alone are not enough. Therefore, it would be desirable to be able to apply maze games and orienteering, which are popular on the ground, to pools, but the mazes mentioned above are molded using many wall materials, It is extremely difficult to directly apply the product underwater in a pool.

(2) On the other hand, in swimming speed practice in the pool,
It is necessary to check what your own speed is compared to the target speed, and conventionally,
After swimming a predetermined distance, the results are compared.

However, especially when practicing long-distance speed,
The results are of course important, but it is preferable to accurately grasp the speed during swimming in order to make detailed improvements. Therefore, it is desired to provide a device that can accurately determine the speed during swimming.3(3)
In addition, in recent years, aquaculture fishing has been actively carried out in the sea and lakes, and in this case, in order to ensure that the aquaculture work is carried out accurately and smoothly, it is necessary to position the work boat precisely at the desired position. It is also necessary to accurately know the boundaries of aquaculture and fishing grounds. Furthermore, when fishing, it is preferable to correctly position the fishing boat at the most important point. Know 1: It's not easy.

(Objectives of the Invention) This invention was made by paying attention to the circumstances described in Section I, and has the following objects.

(1) Make it possible to play underwater mazes, orient pooling, etc., so that you can especially enjoy playing in the boule in 1 minute, (2) If you are already good at swimming speed practice, This practice will be effective if you are able to know your own records. I, let it be sea urchin.

(3) To be able to accurately position ships at sea or on lakes, and to know the boundaries accurately, so that aquaculture work and fishing can be carried out effectively. 7 (Structure of the Invention) The feature of this invention for achieving the above object is that a large number of light emitters are arbitrarily arranged on the bottom surface of the water, and a desired one of the above-mentioned light emitters emits light. It is equipped with a control device λ7 to control the system in the following manner.

(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to the drawings.7 (First Embodiment) FIGS. 1 to 3 show a first embodiment of the present invention.

In the figure, 1 is a boule, and this boule 1 has a rectangular shape when viewed from above. On the bottom 2 of this Boolean l is 7 t
=The light emitters 3 are arranged in a ricks-like manner.

That is, parallel to each other along the longitudinal direction of the bottom surface 2 = IV
A group of 73 rows of light emitters are provided, and the dimensions between each row 1 = +V are the same. Furthermore, when viewed from the width direction of the bottom surface 2, each of the light emitting bodies 3 has the following characteristics:
They are arranged in a row perpendicular to IV, and these are A to I.
(It is made up of rows. Also, the dimensions between A=H in each of these rows are also the same.The light emitting source of the -V-registered light emitter 3 may be single or plural.

There are grooves 4 parallel to each other along the longitudinal direction on the bottom surface 2 of the notebook.
are formed, and three groups of light emitters in rows 1 to 4 are respectively fitted into each groove 4. and,
As shown in FIG. 3, each light emitter 3 is +.

It is connected to a control device 6 by an electric wire 5 laid in the distribution groove 4 .

As shown in FIG. can be seen underwater, and by using the light 7 from each light emitting body 3 as a wall material and mixing it with -0 function, a labyrinth is formed in the water of the boule 1.7 Figure 1 Middle, arrow I
indicates the entrance 1-1 of this maze, arrow 0 indicates the exit, and arrow R in the figure indicates the shortest course from the entrance I to the exit O.

In the case of L, the control device 6 can select which of the light emitters 3 to emit light, the direction of the light 7, and the fan-shaped angle.

By making this selection, the shape of the maze can be changed to a desired shape.

In the above configuration, the position of each light-emitting body 3 is displayed on the light-emitting body 3 itself by the light emission of this light-emitting body 3 (for example,
-1) may be displayed. Also,
This display may be changed by operating the control device 6.

Then, if you use the above-described position display, you can use the maze 111 described above or even without using such a maze,
You can enjoy orienteering inside the boule. In this case, for example, each time the swimmer carries a photoreceptor and passes a predetermined position of the light emitter 3, the swimmer receives the light from the light emitter 3 at that position and accumulates points. You can go as you like.

Further, in the above embodiment, the light emitting bodies 3 are arranged in a matrix shape in which the columns and rows are orthogonal, but the invention is not limited to this. For example, the columns and rows may be inclined at a certain angle. Alternatively, each light emitting body 3 may be arbitrarily arranged.

Furthermore, when the light emitters 3 are arranged on the bottom surface 2, each light emitter 3
It may also be arranged by anchoring it to the bottom surface 2.

(Second example) FIG. 4 shows a second embodiment.

According to this, each light emitting body 3 is used for swimming speed practice, and these light emitting bodies 3 are arranged linearly in plan view, and are made up of groups of three light emitting bodies in columns I to ■. . Then, the control device 6 controls the lights to be turned on sequentially at a predetermined speed from the A side to the H side for each of the columns A to A. Then, the practitioner can judge his/her own speed moment by moment during swimming based on the speed of this lighting. Therefore, the practice can be made effective.

Note that each of the three groups of light emitters in the I-IV rows may be used as a course guide. Further, in the above configuration, each light emitting body 3 is turned on sequentially, but it is also possible to turn off the light one after another, or each light emitting body 3 is provided with a plurality of light emitting sources so that the emitted light color can be changed sequentially. It's okay. Further, the light emitting source may be a laser beam, an LED, an arc, or the like.

Other structures and functions are the same as those of the first embodiment.

Next, the light emitter 3 at the first position is turned on. Then,
The above-mentioned worker who visually recognized this moved to the first position of the work boat 1.
Move 2. Thereby, the work boat 12 is guided by the light emitting body 3 to a desired position.

In FIG. 6, each of the light emitting bodies 3 is provided on a lifting platform 15. As shown in FIG. By the operation of the lifting table 15, each light emitting body 3 is adjusted to a desired shallow water depth. Therefore, even if the water depth of the bottom surface 13 of the aquaculture fishing ground 11 is deep, each light emitting body 3 can be easily recognized from above the work boat 12.

Further, according to the above configuration, the fishing boat can be correctly guided to the point by the same effect as described above.

Furthermore, by lighting up or blinking the luminous body 3 located along the boundary line 17 of the aquaculture fishing ground 11, the boundary line 17 can be accurately known by visual recognition. Convenient for work.

Other configurations and functions are the same as those in the first and second embodiments,
For example, each light emitting body 3 may be arbitrarily disposed on the bottom surface 13, and in this case, each light emitting body 3 may be disposed by being anchored to the bottom surface 13.
