When air is supplied to the pneumatic cylinder 434 according to the opening and closing of the control valve 431, the support rod 435 may protrude from the pneumatic cylinder 434, as indicated by the dotted line in the drawing. The end portion may pass through the opening portion 207 ′ to protrude into the tank 200 ′ from the side wall 201.

On the contrary, since the air is not supplied to the pneumatic cylinder 434 through the pneumatic line 432 when the control valve 431 is closed, the support rod 435 is returned to the position indicated by the solid line, the opening of the side wall 201 It may not protrude through 207 '.

Another example 430 of the lifting floor support means as described above uses pneumatic pressure to operate the support rod 435, and the necessary pneumatic pressure can be obtained only through the pneumatic line 432 connected to the air supply means 210. Therefore, the structure can be simplified, and the possibility of lowering the water quality of the water W stored in the water tank 200 mm can be greatly lowered.

The elevating floor supporting means 430 'which has not been described is the same as the elevating floor supporting means 430 described above, and thus the overlapping description is omitted.

12 to 19 are diagrams for explaining the operation of the variable pool according to an embodiment of the present invention.

12 illustrates a variable pool in accordance with one embodiment of the present invention.

Referring to FIG. 12, the variable pool 1 according to an embodiment of the present invention may include a lift floor 100 and a water tank 200. Here, since the structure of the elevating floor 100 and the structure of the water tank 200 are as described above, the overlapping description is omitted.

The lifting floor 100 may be disposed in the water tank 200.

When the air supply means 210 of FIG. 6 is operated so that no air is supplied into the water W, the lifting floor 100 is positioned on the bottom 202 of the water tank 200 as shown. That is, the lifting floor 100 may be manufactured to have a specific gravity greater than that of water (W), and thus may be positioned on the bottom 202 as shown when the air is not supplied by the air supply means (210 in FIG. 6). .

 At this time, the corrugated portion 112 is in contact with the bottom surface 202, the bubble dispersion means 135 may be accommodated in the hollow 203.

The buffer means 113 may be in contact with the side wall 201 of the tank (200).

For reference, the shock absorbing means 113 is for preventing the floor main body 110 or the floor main body 100 or the side wall 201 from being damaged by collision with the side wall 201. Although not shown, the cushioning means 113 is elastic and covers the foam member (foam member) and the foam member (not shown) coupled to the outer circumferential surface of the floor body 110 and is coupled to the outer circumferential surface of the floor body 110. Cover (not shown).

Or, although not shown, a plurality of guide rollers (not shown) that can guide the relative movement with respect to the side wall 201 of the lifting floor 100 in place of the buffer means 113 on the outer peripheral surface of the floor body (110) It may be combined radially.

When air is not supplied through the branch pipe 211, the outer collecting space 141 and the inner collecting space 142 are filled with water (W), and the exhaust means 150 may be in a closed state. In addition, the lifting floor support means 230 may be in a state where the other side 235b of the L-shaped bracket 235 does not protrude into the sidewall 201.

FIG. 13 shows how the lifting floor starts to rise.

When air is supplied into the water W through the branch pipe 211, the bubble b may move upward from the branch pipe 211. The bubble (b) is collected in the space in the lifting floor 100, that is, the outer collecting space 141 and the inner collecting space 142, and the amount of air as1 collected is increased to act on the lifting floor 100. When the buoyant force becomes greater than the load of the lifting floor 100, the lifting floor 100 may rise from the bottom 202 as shown.

In this case, the exhaust means 150 may maintain the closed state such that the air as1 collected in the outer collecting space 141 and the inner collecting space 142 is not discharged through the exhaust port 116 of FIG. 1.

In FIG. 14, the lifting floor 100 is inclined to one side while being moved in the water tank 200.

The frictional force between the shock absorbing means 113 and the side wall 201 and the air supplied through the branch pipe 211 are uniform in the plurality of outer collecting spaces 141 and the inner collecting spaces 142 due to water flow or the like. If not supplied, the lifting floor 100 may not maintain equilibrium as shown.

When the lifting floor 100 does not maintain an equilibrium state, as illustrated, the air as2 collected in the outer collecting space 141 and the inner collecting space 142 may be biased in an inclined direction. have.

When the collected air as2 is biased, a large buoyant force is applied to a portion of the plurality of outer collecting spaces 141 and the plurality of inner collecting spaces 142 that have a large amount, and relatively small portion of the plurality of outer collecting spaces 141 and a plurality of inner collecting spaces 142. Buoyancy can be applied.

At this time, as shown, the portion in which a large amount of the collected air (as2) is present, the air can be moved to the adjacent outer collecting space 141 through the balance hole 132 formed in the radial partition wall 131, the air The buoyancy force acting on the outer trapping space 141 in which the amount is reduced may be gradually reduced.

In addition, although not shown, since the air flows through the vent groove 134, the air may flow more smoothly between the plurality of outer collecting spaces 141 through the inner collecting space 142.

Since the amount of air (as2) collected in the elevating floor (100) is a state in which buoyancy acting on the elevating floor (100) is greater than the load of the elevating floor (100), if the elevating floor (100) maintains an equilibrium state, the floor body The water surface formed in the 110 may be located below the balance hole 132.

Therefore, the air in the outer trapping space 141 in which some of the collected air as2 is relatively moved is continuously moved to the adjacent outer trapping space 141 through the balance hole 132, and eventually all the outer trapping Air as2 may be evenly distributed to the space 141.

However, when the balance hole 132 descends below the water surface formed by air as the air flows, the flow of air may be blocked, so that the air is relatively out of the plurality of outer collection spaces 141. The air in which much was present remains at least enough to have a neutral buoyancy and only more air can flow.

Therefore, the balance adjusting unit 130 installed on the movable floor 100 of the variable pool 1 according to the embodiment of the present invention may maintain the balance of the floor body 110 by the above-described method.

On the other hand, when the air is continuously supplied through the branch pipe 211 while the balance of the floor body 110 is adjusted by the balance adjusting unit 130, in particular, when the air flows in a biased manner, such as water flow Although the operation of the adjusting unit 130 may be degraded, this phenomenon may be prevented by the bubble dispersing means 135.

In detail, when the lifting floor 100 is inclined, the bubble dispersing means 135 may also be inclined to deviate from the center of the water tank 200 according to the inclining direction of the lifting floor 100.

As such, when the bubble dispersing means 135 is inclined in a specific direction, for example, when the bubble dispersing means 135 is inclined so that the opening 138 faces the direction indicated by R, as shown in FIG. The cone formed by the inclined plate 136 of FIG. 5 may partially block rising of bubbles in the direction R in which the amount of air as2 relatively collected is increased.

In particular, the plurality of fins 137 coupled to the inclined plate (136 of FIG. 5) may collect air (as2) to guide bubbles in a relatively large direction (R) to flow in the opposite direction (L). Accordingly, the amount of air as2 that is collected among the plurality of outer collecting spaces 141 is relatively small, so that a larger amount of air may be supplied.

The lifting floor 100 inclined by the action of the bubble dispersing means 135 may be returned to an equilibrium state more quickly as shown in FIG. 13.

15 shows a state in which the lifting floor is being raised.

Referring to FIG. 15, air is continuously supplied through the branch pipe 211, so that the lifting floor 100 collects a larger amount of air than the captured air (as2 of FIG. 14) described with reference to FIG. 14. Air as3 may be dispersed in the plurality of outer collecting spaces 141 and the plurality of inner collecting spaces 142.

Therefore, since the buoyancy can be applied to the elevating floor 100 by the collected air as3, the elevating floor 100 can be continuously raised in the water (W).

As such, when it is determined that the amount of air as3 collected in the space in the lifting floor 100 is sufficient, supply of air through the branch pipe 211 can be stopped as shown in FIG. 16. That is, FIG. 16 shows a state in which the lifting floor 100 is continuously raised.

By the way, if you want to use the variable pool (1) for other purposes than the pool, the lifting floor 100 is raised as much as possible so that the height of the upper surface of the floor main body 100 has the same height as the upper end of the side wall 201 You can.

To this end, the lifting floor 100 is to be fixed by the lifting floor support means 230, 230 'installed on the side wall 201 (230') installed on the upper side. Therefore, the lifting floor 100 may be further raised so that the lifting floor 100 does not interfere with the lifting floor 100 while the lifting floor support means 230 ′ is operated.

FIG. 17 illustrates such a situation. Even after the lifting floor 100 has sufficient buoyancy as described above, air is further supplied through the branch pipe 211 to collect as much air as possible in the lifting floor 100. (as4).

Therefore, as shown in FIG. 17, sufficient buoyancy is applied to the elevating floor 100 by a large amount of collected air as4, so that the elevating floor 100 can operate the elevating floor support means 230 '. Can be raised enough that interference does not occur.

Subsequently, the other side (235b of FIG. 8) of the L-shaped bracket (235 of FIG. 8) protrudes into the tank 200 as described above with reference to FIG. 8 by operating the lifting floor support means 230 ′ on the upper side. Then, as shown in FIG. 18, when the exhaust means 150 is opened to allow the air (as4 in FIG. 17) collected in the lifting floor 100 to be discharged to the outside, the amount is reduced (as5) to the water (W). As a result, the buoyancy applied to the elevating floor 100 is also reduced. After the air is sufficiently discharged, the exhaust means 150 may be closed again.

Thus, the floor body 110 is supported by the lifting floor support means 230 ′ on the upper side as shown in FIG. 18, such that the upper surface of the floor body 110 is fixed at a position higher than the water surface of the water (W). can do.

Therefore, according to an embodiment of the present invention, as shown in FIG. 18, the elevating floor 100 may cover the tank 200, and thus, the variable swimming pool 1 may be utilized for various purposes such as a stage or an event venue. have.

On the other hand, in order to utilize the variable pool (1) again as a swimming pool should be able to lower the lifting floor 100 in the downward direction of the tank (200). To this end, the floor main body 110 must be released by the lifting floor support means 230 ′.

First, the exhaust means 150 is closed, and then the sufficient amount of air is supplied through the branch pipe 211 so that the lifting floor 100 rises as much as possible. Then, the lifting floor support means 230 ' As described with reference to the other side of the L-shaped bracket (235 of FIG. 7) (235b of FIG. 7) so that it does not protrude into the water tank 200.

Thereafter, when the exhaust means 150 is opened to sufficiently reduce the amount of air collected in the lifting floor 100 so that the buoyancy acting is reduced, the lifting floor 100 descends in the water (W).

At this time, if you want to utilize the variable pool (1) for the purpose of the pool in general, the other side 235b of the L-shaped bracket 235 as described with reference to Figure 8 by operating the lower lifting floor support means 230 ) May protrude from the side wall 201.

Therefore, since the elevating floor 100 that is continuously lowered is supported by the lower elevating floor support means 230 as shown in FIG. 19, the variable pool 1 may be used as a general swimming pool.

If the maximum depth is required to use the variable depth swimming pool 1 for diving training, the lifting floor 100 is closed by closing the exhaust means 150 and supplying air through the branch pipe 211. After being raised above the position shown in 16, the lower lifting floor support means 230 may be operated in a state as described with reference to FIG. 7 so as not to support the lifting floor 100. Then, the supply of air through the branch pipe 211 is stopped, the exhaust means 150 is opened again so that the air collected in the floor main body 110 is discharged, the lifting floor 100 is as shown in FIG. The bottom surface 202 is lowered to obtain the maximum depth of the variable pool 1.

As such, the variable depth swimming pool 1 according to the embodiment of the present invention can change the depth or completely cover the water W to be used as a space for another use.

In particular, since the variable pool 1 according to an embodiment of the present invention utilizes buoyancy to elevate the elevating floor 100, the space for elevating the elevating floor 100 can be minimized. have.

In addition, since the lifting floor 100 can be quickly returned to the equilibrium state even when the lifting floor 100 is inclined without maintaining the equilibrium state, it can be safely used.

20 illustrates another example of the exhaust means of the variable pool according to the embodiment of the present invention.

Another example of the exhaust means 550 can be installed on the top plate 115 '. The exhaust valve 555 may be installed at the exhaust port 116 ′, and the lever 556 that controls the exhaust valve 555 to be opened and closed may be connected to a mechanical timer 557 installed at the top plate 115 ′. The mechanical timer 557 may be provided with a time setting switch 558.

Here, when the predetermined time is set by the time setting switch 558, the mechanical timer 557 adjusts the lever 556 for a predetermined time, while maintaining the open state of the exhaust valve 555 for a predetermined time. After the elapse of time, the exhaust valve 555 may be closed.

Since the mechanical timer 557 is well known as a mechanical gas valve shutoff device, a detailed description thereof will be omitted.

Another example of such an exhausting means 550 is to operate the variable pool (1 of FIG. 12) according to an embodiment of the present invention as described with reference to FIGS. After opening 116 of FIG. 4, it can be automatically closed, thereby increasing convenience since the operator does not need to access the exhaust port 116 of FIG. 4.

For reference, the floor body described with reference to FIG. 1 (110 in FIG. 1) is not shown, but various shapes such as prismatic shapes depending on the shape of the water tank (200 in FIG. 12) of the variable core pool (1 in FIG. 12). And it can be manufactured in a size, accordingly, the top plate 115 can also be manufactured in various shapes and sizes, such as polygons.

When using the variable pool of water (1 in FIG. 12) according to an embodiment of the present invention for the use of a swimming pool, it should be possible to determine whether the water quality meets the specifications of the swimming pool. Therefore, water quality inspection means (not shown) that can inspect the water quality of the water W may be further installed on the bottom surface (202 in FIG. 12) or side surface (201 in FIG. 12) of the water tank (200 in FIG. 12). have.

In addition, when the variable pool (1 in FIG. 12) according to an embodiment of the present invention is used as an amusement facility, the bottom (202 in FIG. 12) or the side (201 in FIG. 12) of the tank (200 in FIG. 12) is used. The lighting means (not shown) is installed, and the upper plate (115 in FIG. 1) of the floor body (110 in FIG. 1) is made of a light-transmitting material such as tempered glass, so that light emitted from the lighting means (not shown) is emitted. By allowing the upper plate (115 in FIG. 1) to penetrate, entertainment can be increased.

By the way, the side surface 201 and the bottom surface 202 of the water tank (200 of FIG. 12) need to be periodically cleaned, etc., and the above-mentioned water quality inspection means (not shown), lighting means (not shown), etc. Maintenance may be necessary. To this end, a hatch (not shown) may be installed on the top plate 115 of the floor main body 110 of FIG.

On the other hand, when the elevating floor (100 in FIG. 12) is elevated in the water tank (200 in FIG. 12), the elevating floor (100 in FIG. 12) in order to avoid interference with the elevating floor support means (230, 230 'in FIG. 12). It is necessary to grasp the position raised from the bottom (202 of FIG. 12) of the bottom surface. To this end, a plurality of proximity sensors (not shown) may be distributed on the sidewall 201 of FIG. 12, and the position of the lifting floor (100 of FIG. 12) is detected by the proximity sensors (not shown).
