Description

artificial wave generation system

The present invention relates to an artificial wave generating system, and more particularly, to a system for artificially generating a wave including a barrel.

Recently, interest in water leisure sports among young people is growing, and among them, surfing is gaining more and more enthusiasts mainly from young people, and it has established itself as a popular summer leisure sport for many people due to its excellent exercise effect.

However, in order to enjoy such surfing, it takes a lot of time and money to go to the suburbs, and there is a problem that it is difficult to meet the waves that surfers want because the waves are not constant due to the influence of the environment such as weather.

To solve this problem, a facility that creates artificial waves indoors has been developed. However, this indoor wave device has disadvantages in that it is difficult to make a wide surfing facility due to space limitations, and it is difficult to create a barrel, which is a cylindrical wave preferred by advanced users.

Of course, technology for generating waves including barrels has also been developed in the past, but the structure is very large and complex. In particular, conventional artificial wave generators required a sufficiently wide water tank to generate a barrel. This is because the barrel is generated from a location far away from the wave generator. Therefore, there was a limit to its application because it basically required a very wide water tank.

In addition, the conventional artificial wave generator can only control the intensity of the wave, and there is a limitation in that it is difficult to create waves of various sizes and shapes required by surfers, including the barrel, as appropriate.

In addition, most of the existing artificial wave generators operate in a state where most facilities are installed underwater. Therefore, since waterproofing of the equipment is absolutely necessary, the equipment is complicated, and it is difficult to visually check the operating state of the equipment, and there is a problem in that the maintainability of the equipment is poor.

In addition, a part of the artificial wave generator extends to the center of the tank or generates waves while moving toward the center of the tank, so the space required for the installation of the device is very wide, and accordingly the cost for installing the device increases. there is

The present invention is to solve the problems of the prior art as described above, and an object of the present invention is to generate a wave including a barrel through an artificial wave generating system.

Another object of the present invention is to generate a barrel only with a wave generating means that reciprocates or rotates along a predetermined path and a projecting end structure of a water tank bottom.

Another object of the present invention is to submerge only the hydrofoil connected to the wave generating means in the water and the driving means of the wave generating means to be located outside the water tank.

Another object of the present invention is to make it possible to produce various types of barrels by adjusting the angle of a hydrofoil.

According to a feature of the present invention for achieving the above object, the present invention includes a protruding end protruding upward from the bottom surface of a space in which a fluid is accommodated, and a track portion provided to be adjacent to the protruding end to form a constant path; , It moves or rotates along the track, and includes a wave generating means for generating a wave in the direction of the protruding end of the hydrofoil, which is at least partially in contact with the fluid surface during the movement or rotation process.

The protruding end gradually increases in height along the moving direction or rotational direction of the wave generating means from the bottom of the surf pool.

There are a first inclined surface whose height gradually increases along the moving or rotational direction, and a second inclined surface whose height gradually increases as the distance from the track unit increases along a direction orthogonal to the moving or rotating direction of the wave generating means.

The protruding end is configured in a stepwise manner that gradually increases in height along a direction away from the wave generating means toward the center of the surf pool.

The protruding end is provided in plurality along the longitudinal direction of the track portion, is provided at one end and the opposite end of the track portion, the initial stage when the wave generating means starts moving in the first direction, and the second opposite to this Each of the protruding ends may generate a wave at the beginning of movement in the direction.

The wave generating means includes a driving module that moves along a straight or curved path along the track portion, and is coupled to the driving module and moves with the driving module in a state in which at least a portion is submerged in the surfing pool while moving with the water of the surfing pool. It includes a hydrofoil for pushing in the direction of the protruding end.

A plurality of the driving modules are connected to each other, and the hydrofoil is connected to each of the driving modules.

The track part is separated from the surfing pool to form an independent space, and a power module for supplying power to the driving module is provided at a position adjacent to the track part.

A partition wall is installed between the track part and the surf pool, and a connection channel through which a connection means for connecting between the drive module of the wave generating means and the hydrofoil connected to the drive module passes is formed in the partition wall .

The driving module is an electric vehicle operated by the third rail current collecting method.

The driving module has a caterpillar structure that continuously rotates along a predetermined trajectory located in the track unit.

The hydrofoil is moved in a state in which at least a portion is submerged in the surfing pool, and the end of the hydrofoil extends to a position lower than the upper end of the protruding end.

The hydrofoil has a cross-sectional shape in which the center protrudes forward based on the moving direction or the rotational direction of the wave generating means in order to generate drag in the water.

The hydrofoil gradually becomes thinner in the direction of the surf pool at the point where it is connected to the driving module of the wave generating means.

The hydrofoil is rotatably connected to the driving module of the wave generating means about the rotation axis in the direction parallel to the depth direction of the surfing pool, the inclination angle of the hydrofoil for generating drag in water is adjustable.

The hydrofoil is rotatably connected to the driving module of the wave generating means around a rotational shaft extending in the direction of the surfing pool from the wave generating means, and may be rotated according to the moving direction of the driving module.

The hydrofoil has a shape in which both sides are symmetrical with respect to an imaginary center line extending along the center of the hydrofoil.

The wave generating means is provided with a truss arm, and the hydrofoil is fixed to the truss arm.

The surfing pool adjacent to the track portion is provided with a safety net spaced apart from the track portion, and the hydrofoil is positioned between the safety net and the track portion.

The surfing pool is provided on both sides of the track part around the track part, respectively, and the wave generating means is provided so that the hydrofoils protrude toward the surf pools on both sides, respectively.

As discussed above, the artificial wave generating system according to the present invention has the following effects.

In the process of moving (or rotating) the wave generating means constituting the artificial wave generating system, it generates waves while pushing water in the direction of the protruding end. These waves generate a difference in flow velocity inside the surf pool to create barrel-shaped waves. creates Therefore, users can use barrel-shaped waves rather than simple waves, so they can enjoy more advanced surfing.

And, according to the present invention, it is possible to provide a barrel-shaped wave only with a wave generating means that moves or rotates along a predetermined path and a protruding end at the bottom of the surf pool adjacent thereto. As such a very simple structure can create a barrel-shaped wave, it is possible to easily make a facility at a relatively low construction cost compared to the prior art.

In addition, in the present invention, the protruding end at the bottom of the surf pool creates a difference in flow velocity depending on the depth of the surf pool, and the difference in flow velocity creates a barrel-shaped wave. Therefore, it is possible to generate a desired wave only in a short moving section without the need for the wave generating device to move in a long section, and as a result, the wave generating equipment can be miniaturized.

And, in the present invention, only the hydrofoil constituting the wave generating means is submerged in the surf pool, and the driving means is installed in the track part, which is a space independent from the surf pool. Therefore, since the driving means located in the track has relatively little influence of the surf pool, it is possible to lower the failure rate due to moisture, and since it is installed in an independent space, there is an effect of easy waterproofing.

In addition, the hydrofoil constituting the wave generating means in the present invention is angle adjustable. Depending on the angle change of the hydrofoil, the magnitude of the drag generated in the water changes, and accordingly, the shape and size of the generated wave can be adjusted. Therefore, rather than simply adjusting the speed of the wave generating means, it is possible to provide more diverse waves by adjusting the inclination angle of the hydrofoil, thereby satisfying various users.

And, in the present invention, the wave generating means may be configured to travel along a closed curved path, but may reciprocate along a predetermined path. At this time, the direction of the hydrofoil can be rotated 180° according to the movement direction of the wave generating means. In this way, the same wave can be generated regardless of the movement direction of the wave generating means, and since waves can be continuously generated in a small space, it is possible to reduce the size of the equipment.

In addition, in the present invention, surf pools are provided on both sides of the track part around the track part, and the hydrofoils may respectively protrude toward the two surf pools on both sides of the wave generating means. In this way, since both surf pools can be used on both sides, a double barrel wave can be created with one wave generating means, and the space utilization rate of the surf pool can be increased.

Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. In adding reference numerals to the components of each drawing, it should be noted that the same components are given the same reference numerals as much as possible even though they are indicated on different drawings. In addition, in describing the embodiment of the present invention, if it is determined that a detailed description of a related known configuration or function interferes with the understanding of the embodiment of the present invention, the detailed description thereof will be omitted.

The present invention relates to an artificial wave generating system, and is for stably generating a constant wave (B) without being affected by environmental conditions indoors or outdoors. As will be seen below, it is possible to generate a wave B by the organic action of the wave generating means 30 and the protruding end 10 on the bottom 2 of the surf pool 1, and in particular, the cylindrical barrel B '), the formed wave (B) is created.

For reference, the wave (B) in which the barrel (B') is formed refers to a shape in which the wave (B) is rolled in a cylindrical shape, and is also referred to as a tube. Referring to FIG. 1 , there is an empty space curled inside the wave (B), and this type of wave (B) is called a wave (B) in which the barrel (B') is formed. Since the waves (B) in which these barrels (B') are formed are made under specific environmental conditions, it is difficult to meet them easily in a general natural environment. In the present invention, it is possible to artificially create a wave (B) in which such a barrel (B') is formed through the following structure.

First, looking at Figure 1, there is a surfing pool (1) filled with water (W) in a predetermined space. The surf pool (1) is a space in which the fluid is accommodated. The surfing pool (1) includes a bottom (2) and a side wall (3), the inside is filled with water (W). The surf pool (1) may have a predetermined depth and width, but only a portion is expressed in the drawings. The surfing pool 1 may be provided indoors or outdoors. However, as shown in the drawings, it is preferable that the structure is capable of confining water W.

The bottom (2) of the surfing pool (1) has a protruding end (10). The protruding end 10 has a structure that protrudes from the bottom 2 of the surfing pool 1 from the bottom. The protruding end 10 is a structure that substantially creates a wave B in which a barrel B' is formed together with a wave generating means 30 to be described below, and is located on the bottom 2 of the surf pool 1 It may be made integrally or may be installed detachably.

The protruding end 10 is located adjacent to the track portion 35 on which the wave generating means 30 moves. When the protruding end 10 is in a position adjacent to the track part 35 , the water W may be pushed in the direction of the protruding end 10 by the wave generating means 30 moving the track part 35 . . 1, it can be seen that the protruding end 10 protrudes in a position adjacent to the track portion 35, and may extend longer in the central direction of the surf pool 1 differently from the illustration.

The protruding end 10 protrudes high from the bottom 2 of the surf pool 1 to interfere with the flow of water W. That is, if the protruding end 10 is positioned higher than the bottom 2 of the surf pool 1 in this way, it is possible to create a flow velocity difference according to the depth of the surf pool 1 .

3, in the process in which the hydrofoil 60 of the wave generating means 30 to be described below moves together with the wave generating means 30, the moving direction of the wave generating means 30, that is, in the direction of the arrow ① W) creates a flow, and in a deep place close to the bottom (2) of the surf pool (1), the flow rate is reduced in the process of crossing the water (W) over the protrusion (10). That is, the water (W) flowing in the direction of the arrow ② in FIG. 3 has a relatively reduced flow rate. On the other hand, in a low place close to the water surface (W1) of the surf pool (1), the water (W) has a relatively high flow velocity because it is not disturbed by the protruding end (10) (arrow ③ direction). Due to this flow velocity difference, a wave B in which the barrel B' is formed is created on the water surface W1. Therefore, the user (P) can use the wave (B) in the form of a barrel (B') rather than a simple wave (B), so that he can enjoy a more difficult surfing.

In this embodiment, the protruding end 10 gradually increases in height along the moving direction or rotational direction of the wave generating means 30 in the bottom 2 of the surfing pool 1 . That is, the side surface of the protruding end 10 becomes the inclined inclined surface 15 . Accordingly, the water (W) flowing in the deep position can ride over the protrusion end 10 naturally, and it is possible to prevent the flow rate from being excessively reduced. The upper surface 17 of the protruding end 10 may be a flat surface, an inclined surface, or a curved surface.

Meanwhile, referring to FIG. 4 , the protruding end 10 has inclined

surfaces

15 and 16 in various directions. More precisely, the protruding end 10 has a first inclined surface 15 and a second inclined surface 16, the first inclined surface 15 is the wave generation at the bottom (2) of the surf pool (1) The height gradually increases along the moving or rotating direction of the means 30 . In addition, the second inclined surface 16 gradually increases in height as it moves away from the track part 35 in a direction perpendicular to the movement or rotation direction of the wave generating means 30 .

As a result, the first inclined surface 15 and the second inclined surface 16 are formed on different sides of the protruding end 10, respectively, and can have the same function of slowing the flow rate at a deep water position. Of course, the second inclined surface 16 may be omitted, or may be made of an outer surface continuous with the first inclined surface 15 .

As shown in FIGS. 1 and 2 , the protruding end 10 is spaced apart from the track part 35 . Accordingly, a predetermined flow space S exists between the protruding end 10 and the track part 35, and is represented by reference numeral S in FIG. 4 . This flow space (S) allows the aforementioned second inclined surface (15) to also function to reduce the flow rate, and prevent a dead space from occurring between the protruding end (10) and the track part (35).

The protruding end 10 may be composed of several layers having different heights from each other. Referring to FIG. 5 , the protruding end 10 has a first inclined portion 10A located at a position close to the track portion 35 with respect to the safety net 90 , and gradually higher than the first inclined portion 10A. The second inclined portion 10B and the third inclined portion 10C of which is increased are continuously arranged to constitute the protruding end 10 . In this way, the protruding end 10 may be configured in a stepwise manner that gradually increases in height along a direction away from the wave generating means 30 toward the center of the surf pool 1 . Alternatively, the protruding end 10 may be configured in a stepwise manner in which the height gradually increases along the movement path of the wave generating means 30 .

For reference, the height of the protruding end 10 is expressed higher than the actual height in FIGS. 3 and 4 to help understanding, and the height of the protruding end 10 may vary in proportion to the total depth of the surf pool 1 . .

A plurality of the protruding ends 10 may be provided along the longitudinal direction of the track part 35 . A plurality of the protruding ends 10 may be disposed to be spaced apart from each other. For example, the protruding end 10 is provided at one end and the opposite end of the track part 35 so that (i) the wave generating means 30 moves in the first direction (direction of arrow ① in FIG. 1). At the initial stage of starting to move and (ii) at the beginning of moving in the opposite second direction (direction opposite to the arrow ① in FIG. 1 ), the protruding end 10 can generate a wave (B), respectively. . Referring to FIG. 8 , there is a protruding end 10 at the upper end of the movement initial position based on the moving direction (arrow ① direction) of the driving module 40, and the protruding end 10 also at the stop position corresponding to the opposite end. there will be Of course, a larger number of the protruding ends 10 may be disposed at intervals.

One side of the surfing pool (1) has a track portion (35) constituting the wave generating means (30). The track part 35 is provided along the edge of the surfing pool 1, and forms a kind of path. The driving module 40 of the wave generating means 30 is installed in the track part 35 , so that the driving module 40 can move or rotate along the track part 35 . In this embodiment, the track part 35 is a straight path, but the track part 35 may have a closed curved path or an arc-shaped path.

Referring to FIG. 1 , the track part 35 has a space independent of the surf pool 1 based on the partition wall 20 . Although the track part 35 makes a path for the wave generating means 30 to move, devices for driving the driving module 40 of the wave generating means 30 may be installed therein. The track part 35 becomes a driving space, and the driving module 40 of the wave generating means 30 such as an electric vehicle can run along the bottom surface 36 of the driving space. Reference numeral 45 denotes a wheel of the driving module 40 . In this embodiment, the track part 35 is a component distinct from the surf pool 1 , but otherwise, the track part 35 may be viewed as a part of the surf pool 1 .

As an example of the devices for configuring the wave generating means 30, when the wave generating means 30 is a moving electric vehicle operated by electricity as a driving source, the track part 35 includes the wave generating means 30. A power module for supplying power may be provided. As an example of such a power module, the power module may continuously supply power to the driving module 40 of the wave generating means 30 that travels, including a three-track type electric power line and a power line.

The driving module 40 of the wave generating means 30 is installed in the track part 35 . The driving module 40 moves or rotates along the track part 35, and the hydrofoil 60, at least partially submerged in the surf pool 1 in the process of movement or rotation, waves in the direction of the protruding end 10. causes The driving module 40 may be an electric vehicle that runs along the track part 35 or a caterpillar that continuously rotates along a predetermined track located on the track part 35 . That is, the driving module 40 may have various shapes that are driven along a predetermined path in the track part 35 .

In this embodiment, the wave generating means 30 includes a driving module 40 and a hydrofoil 60 . The driving module 40 is to move along a straight or curved path along the track part 35 , and the hydrofoil 60 is coupled to the driving module 40 and at least a portion of the surf pool (1). It is to push the water (W) of the surf pool (1) in the direction of the protruding end (10) while moving together with the driving module (40) in a locked state.

That is, since the driving module 40 is installed in the track part 35, it is not directly submerged in the surf pool 1, and only the hydrofoil 60 connected to the driving module 40 is operated in a submerged state in the surf pool 1 . The track part 35 is partitioned by the partition wall 20 described above, and the driving module 40 and the hydrofoil 60 are connected through the connection channel 25 in the partition wall 20, so the surfing pool ( 1) can be minimized. A connection means 43 for connecting between the driving module 40 and the hydrofoil 60 passes through the connection channel 25 . Of course, the connection channel 25 may be omitted, and the drive module 40 and the hydrofoil 60 may be connected beyond the upper end of the partition wall 20 .

When the bottom surface 36 of the running space of the track part 35 is higher than the water surface W1 of the surfing pool 1, it is possible to prevent moisture from entering the running space. Alternatively, even when the connection channel 25 is higher than the water surface W1 of the surfing pool 1, it is possible to mostly prevent moisture from entering the driving space. In this case, the driving module 40 installed in the driving space is naturally waterproof, and separately, the driving module 40 may be subjected to corrosion prevention treatment.

At this time, when the bottom surface 36 of the running space is installed to be inclined downward in the direction of the partition wall 20 at a predetermined angle, the water W of the surf pool 1 introduced can be naturally discharged.

As shown in FIG. 3 , a plurality of the driving modules 40 may be connected to each other, and the hydrofoil 60 may be connected to each of the driving modules 40 . If the drive module 40 is an electric vehicle, the drive module 40 is connected to a connection device 48 such as a separate link or coupling to move together, and the hydrofoil installed in each drive module 40 ( 60) plays a role in generating this wave. Since the driving modules 40 are detachably connected to each other, the number of the driving modules 40 may be appropriately adjusted according to the size of the surf pool 1 or the number of users P.

A hydrofoil 60 is installed in the driving module 40 . The hydrofoil 60 is a part that generates waves through drag (抗力, drag) while moving in a state in which at least a portion is submerged in the surfing pool (1). One end of the hydrofoil 60 is connected to the driving module 40 to generate drag while moving together with the driving module 40 .

As shown in Figures 3 and 5, the lowermost end of the hydrofoil (60) is preferably extended to a position lower than the upper surface (17) is the upper end of the protruding end (10). Accordingly, the hydrofoil 60 may generate a flow of fluid from the deepest point of the surf pool 1 or a portion adjacent thereto. Of course, the end of the hydrofoil 60 does not necessarily extend to a position lower than the upper surface 17 of the protruding end 10, but extending to a position adjacent to the protruding end 10 is the barrel (B') It is advantageous for the generation of this formed wave (B).

6 shows an embodiment of the hydrofoil (60). As can be seen, the hydrofoil 60 has a cross-sectional shape in which the center protrudes forward based on the moving direction (arrow direction in FIG. 6) or the rotational direction of the wave generating means 30 in order to generate drag in the water. . For example, the front surface 62 of the hydrofoil 60 may protrude in a round shape in the center, and the rear surface 64 has a concave shape on the contrary.

The hydrofoil 60 is gradually thinner in the direction of the surf pool 1 at the point where it is connected to the drive module 40 of the wave generating means 30 . In this case, excessive drag is generated in the process of moving the hydrofoil 60 together with the driving module 40 to prevent the force required to propel the driving module 40 from increasing beyond a certain level.

On the other hand, the hydrofoil 60 may be rotatably connected to the driving module 40 of the wave generating means 30 around a rotation axis in a direction parallel to the depth direction of the surfing pool (1). In this case, the hydrofoil 60 can be adjusted to the angle of inclination of the hydrofoil 60 for generating drag in the water. In FIG. 6, arrows A and A' indicate the direction of rotation, and in FIG. 2, the inclination adjustment direction of the hydrofoil 60 is expressed as A, A'. In this way, by adjusting the inclination angle of the hydrofoil 60, the magnitude of the drag can be adjusted, and the size or shape of the generated wave B can be adjusted accordingly. For example, the generated wave (B) is not necessarily limited to the wave (B) in which the barrel (B') is formed, and a wave (B) having a relatively low wave height may be generated.

In addition, the hydrofoil 60 may be rotatably connected to the drive module 40 of the wave generating means 30 about a rotational shaft extending in the surf pool 1 direction from the wave generating means 30 . . In this case, the direction of the front surface 62 and the rear surface 64 of the hydrofoil 60 may be changed. Arrow B in FIG. 6 indicates this rotational direction. When the hydrofoil 60 rotates in this way, the direction in which the front side 62 faces can be rotated 180° according to the moving direction of the driving module 40, and in this case, regardless of the moving direction of the wave generating means 30, the same Wave (B) can be generated. Of course, it is not necessary to rotate the hydrofoil 60 by 180 degrees in the direction of the arrow B, and the drag force by the hydrofoil 60 may be adjusted by rotating only a predetermined angle.

Alternatively, as shown in FIG. 7 , the hydrofoil 60 may have a shape in which both sides are symmetrical with respect to an imaginary center line extending along the center of the hydrofoil 60 . Since the hydrofoil 60 is symmetrical, it does not need to be rotated in the arrow B direction of FIG. 6 according to the moving direction of the driving module 40 .

As such, the hydrofoil 60 is a portion in which drag is generated, and stress may be concentrated in the connection portion of the hydrofoil 60 and the driving module 40 . In order to supplement this part, as shown in FIG. 9 , the wave generating means 30 is provided with a truss arm 49 , and the hydrofoil 60 may be fixed to the truss arm 49 .

The truss arm 49 is composed of a pair and together with the driving body 41 of the driving module 40 constitutes a substantially triangular shape. And, since the hydrofoil 60 is fixed to the portion where the pair of truss arms 49 meet, the stress concentrated on the hydrofoil 60 can be dispersed.

On the other hand, as shown in Figure 9, the bottom (2) of the surf pool (1) may be provided with a pump (80). More precisely, a pump 80 is provided on the bottom 2 of the surfing pool 1 adjacent to the protruding end 10, and the pump 80 moves in the direction of movement of the driving module 40 and the hydrofoil 60. By pumping water (W) in the same direction as, it is possible to create more flow of water (W) in the deep part of the surf pool (1) by assisting the hydrofoil (60).

Arrows

2 and 3 in FIG. 9 indicate directions in which the fluid is pumped by the pump 80 .

As shown in FIG. 8 , the surfing pool 1 is provided on both sides of the track part 35 around the track part 35 , and the wave generating means 30 has the surfing pools 1 on both sides. ) may be provided so that the hydrofoil 60 protrudes toward each. Therefore, it is possible to create a wave (B) in which the barrel (B') is formed at the same time in the two surf pools (1) on both sides, and the two surf pools (1) can be used. The protruding end 10 ′ located on the left side with reference to the drawing may have a position and structure symmetrical to the protruding end 10 on the right side.

On the other hand, the surf pool (1) adjacent to the track part (35) is provided with a safety net (90) spaced apart from the track part (35). 2 and 5, the safety net 90 is a safety means for preventing the user P from colliding with the hydrofoil 60, between the safety net 90 and the track part 35. A hydrofoil 60 is positioned. The safety net 90 does not impede the generation of waves because the flow of fluid therebetween is possible.

Referring to FIG. 2 , a platform 100 may be provided in the surfing pool 1 . The platform 100 is installed in the middle of the surf pool 1, is installed above the water surface W1 of the surf pool 1, and the user P is resting or waiting to ride the wave B. become a place The platform 100 may be installed across the surf pool 1, and may be in the form of a kind of bridge.

And, in the above embodiment, the track part 35 is provided as an independent space on one side of the surfing pool 1, but unlike this, the wave generating means 30 without a separate track part 35 is the surfing pool ( 1) may exist in a locked state. In this case, the wave generating means 30 may generate a wave while moving or rotating inside the surfing pool 1 in a waterproofed state.

Next, a process of generating waves using the artificial wave generating system of the present invention will be described.

First, as shown in FIG. 1, when power is supplied to the wave generating means 30 installed in the track part 35, the driving module 40 of the wave generating means 30 moves along the track part 35 in one direction ( Move in the direction of arrow ①). At this time, the hydrofoil 60 is connected to the driving module 40 , and the hydrofoil 60 also moves together with the driving module 40 . The hydrofoil 60 generates a wave while moving, and generates a wave B in a direction different from the moving direction of the track part 35, more precisely, in the central direction (arrow ② direction) of the surf pool 1 .

More precisely, as shown in FIG. 2 , a plurality of drive modules 40 connected to each other move at the same time, and at the same time, the hydrofoils 60 provided in each drive module 40 move in a state submerged in water (W). A drag force is generated by the water (W) of the surf pool (1). In this process, a wave B in which the barrel B' is formed by the protruding end 10 may be generated.

The protruding end 10 is provided at the initial position of the driving module 40 , and therefore, when the driving module 40 is operated, the influence of the protruding end 10 is immediately applied to the wave. 3, the hydrofoil 60 extends close to the bottom 2 of the surfing pool 1, and generates a wave while moving in this state. pass Therefore, the water (W) is pushed toward the inclined surface (15) of the protruding end (10) and the flow rate is reduced, and the flow rate is relatively slower than that of the water (W) in a shallow area, so that the barrel (B')-shaped wave (B) will occur

When the driving module 40 moves to the opposite end of the track part 35 while creating a wave B in which the barrel B' is formed, the driving module 40 again reverses the direction and returns to the initial position. have. At this time, since the protruding end 10 is also provided on the bottom 2 of the surf pool 1 adjacent to the opposite end of the track part 35, in the process of driving the driving module 40 in the opposite direction, the barrel ( A wave (B) in which B') is formed can be made.

At this time, since the hydrofoil 60 is rotatable as described above, the hydrofoil 60 rotates 180 degrees (arrow B direction in FIG. 6 ) to have the same shape as the initial driving. Therefore, the hydrofoil 60 can generate a wave (B) of the same shape. Of course, the drag force may be adjusted while the hydrofoil 60 rotates in the arrow A or A' direction of FIG. 6 . The size or shape of the wave (B) is also adjusted by the controlled drag.

The user P can ride the wave B in which the barrel B' created in the surf pool 1 is formed, and can ride the wave B and move in the same direction as the driving direction of the driving module 40 . If the user P is a beginner, it is possible to reduce the drag by reducing the size of the wave B or rotating the hydrofoil 60 through the driving module 40 of the caterpillar structure described above. The angle adjustment of the hydrofoil 60 or the speed adjustment of the driving module 40 can be controlled remotely from the control unit away from the surfing pool (1).
