The present invention relates to a disassembly / descent system of a submersible structure within a volume of water, as well as to an associated method of raising / lowering a submersible structure with a volume of water. The invention finds a preferred application, and not limiting, for the descent / descent of a submersible mobile floor pool pond.However, other applications can be envisaged, such as the descent / descent of a submerged structure within a volume of natural water, such as a body of water, a lake, a watercourse, a stretch of sea, ...

In addition, other types of submerged structure can be envisaged, such as for example an underwater culture structure (pigeonhole, ...), a platform, a support structure for marine gear (ber or support cradle for boat, ...).

In the context of an application dedicated to the rise / descent of a submersible mobile pool basin, it is known to use up / down systems to move vertically such a floor between a submerged position in support on a bottom of the pool (to allow lanage) and a position emerged above the water level (to form a protective and insulating cover, while providing a walking surface) As such, a first known up / down system consists of a motorized mechanical system using a motor deporting a cable or chain device via deflection devices, such as pulleys, to move the submersible floor vertically.

However, this first system has the disadvantage of bewitching, the purchase and maintenance of the engine, and unreliable in a wet environment for the engine and cables or chains.

A second known ascent / descent system consists of a pneumatic system employing airbags and ballasts connected to a pneumatic inflator to inflate / deflate the cushions that are placed under the submersible floor.

However, once inflated, the cushions occupy a volumedans the basin which forces to provide a displacement of a part of the water dubassin to a buffer tank, which has the disadvantage of being expensivecar calling earthworks to provide such a buffer tank near the basin.

Thus, this up / down system exploits the incompressible nature of the water to form at least one lifting pillar which, when filled with water, constitutes a stable support for the submersible structure, without the need for a buffer tank because it is the water itself. the volume of water (eg water from the pool) used to fill the lift post (s).

In addition, this up / down system is reliable because appealing to a pump connected to one or more lifting pillars, withoutmechanism complex. The envelope of the at least one lift pillar may have a general column shape in deployed configuration with a cylindrical peripheral device, a high circular plate and a low circular plate.

In a particular embodiment, the floor further comprises at least ballast element so that the floor is non-floating. The addition of at least one ballast element is advantageous for rendering the floor non-floating, or flowing, when the main elements constituting the floor (transverse beams, longitudinal beams and platform) are made of materials providing buoyancy, such as wood, composite or plastic material, or aluminum. The ballast element (s) will thus cancel this buoyancy and make the deck non-floating.

This or these weighting elements can be placed on the support structure of the floor, below the blades, and can for example be made in the form of concrete slabs.

Alternatively or additionally, this or these ballast elements can be placed on the blades, in particular being made in the form of traffic slabs, such as fiber concrete slabs or tiles tiling.

On the other hand, if the platform is made of heavy materials that contribute to the floor being non-floating, which would be the case with a platform composed of fiber concrete slabs or tile slabs, then it would not be necessary to add additional ballast.

Advantageously, the floor supports guiding devices of rolling members shaped to roll along the peripheral structure, and in particular along some of the vertical posts, during the vertical displacements of the floor, for a guidance of the floor along the side panels during the climbs / descents.

With reference to FIG. 1, a swimming pool 1 in accordance with the invention comprises a swimming pool 10 composed of the assembly of enbois elements.

The basin 10 comprises a bottom structure 2 which comprises a plurality of transverse joists 21 arranged side by side and at regular intervals and one or more longitudinal joists 22 intersecting the transverse joists and fixed on the transverse joists 21.

The transverse joists 21 and the longitudinal jamb 22 are wooden and can be assembled by screwing or bolting, possibly with the use of brackets or brackets.

The basin 10 comprises a peripheral structure 3 supported by the bottom structure 2 and comprising: - a lower frame 31 fixed to the bottom structure 2; an upper frame 32 on which is fixed a periphery lip 33peripheral; vertical posts 34 fixed between the lower frame 31 and the upper frame 32; - Side panels 35 fixed on the posts 34 and between the lower frame31 and the upper frame 32.

The lower frame 31 and the upper frame 32 are composed of the assembly of wooden profiles, which can be assembled by screwing and / or bolting and / or tenon / mortise connection, with possibly the use of squares or fixing lugs.

The vertical posts 34 are made of wood, and are fixed on the lower frame 31 and on the upper frame 32 assembled by screwing and / or bolting and / or tenon / mortise connection, with possibly the use of squares or fixing lugs.

The side panels 35 are made of wood, and may comprise several wooden boards fixed on beams, and these side panels 35 are fixed to the vertical posts 34 by screwing or bolting, with possibly the use of brackets or brackets.

As can be seen in FIG. 1, after the installation of the pelvis 10, the support legs 36 can be installed in such a way as to better stabilize the casing 10. These holding legs 36 have a lower end which rests on the floor of the previously dug hole, and an upper end which is fixed to the upper frame 32 by means of fastening such as glue, screws, or nails.

These holding legs 36 are preferably located at the level of certain vertical posts 34 thus making it possible to provide a fixed support to each of these vertical posts 34.

The pool 1 also comprises a sealing layer 11 (partially visible in FIG. 9) disposed beneath the bottom structure 2 and around the peripheral structure 3 for sealing the basin 10.

The pool 1 also comprises a layer of geotextile fabric 12 (partially visible in FIG. 9) disposed below the sealing layer 11; the sealing layer 11 is thus interposed between the layer of geotextile fabric 12 and the basin 10.

Once dug a hole in the ground to receive the basin 10, the layer of geotextile fabric 12 is deposited on the bottom and the sides of the hole. This layer of geotextile fabric 12 makes it possible to avoid subsequent inconveniences that may be caused, such as the growth of roots that may damage the basin 10 and / or the sealing layer 11.

The layer of geotextile fabric 12 may be cut to adopt the dimensions of the basin, and its thickness may for example vary from 0.5 to 5 millimeters.

The sealing layer 11 gives the imperviousness to the pool 10 and prevents water from escaping from the pool 10. This sealing layer 11 is made of rubber or any other plastic material which is sealed to the person skilled in the art. than polyvinyl chloride or polyethylene.

This sealing layer 11 can be cut according to the desired dimensions, and has a thickness of, for example, between 1 and 5 millimeters. It is deposited in such a way as to cover the pre-laid layer of canvas-fabric 12, following the outline of the hole in which basin 1 is placed.

In a preferred embodiment, another layer of canvas-fabric (not shown) may be deposited so as to cover the sealing layer 11. This other layer of geotextile fabric, in addition to protecting the sealing layer 11 of the mechanical friction of the basin 10, avoids damaging this sealing layer 11 during the installation of the bottom structure 2 and the peripheral structure 3.

Once its various layers 11, 12 are put in place, it is advisable to set up the bottom structure 2 and the peripheral structure 3. As can be seen in FIG. 1, it is conceivable that the bottom structure 2 rests on studs or feet 23 distributed on the sealing layer 11.

When the structure of the basin 10 is made, the sealing layer 11 and the layer of geotextile fabric 12 are folded on the upper frame 32 so as to form a seal. The upper edges of theselouches 11, 12 are then blocked by means of attachment provided to this effect and located at the upper part of the upper frame 32. These hooking means can be in several forms, such as for example a rail placed on the upper part of the upper frame 32 or on the lamargelle 33 fixed on the upper part of the upper frame 32. These layers 11, 12 can also be folded down on the upper frame 32 before fixing lamargelle 33 which allows to maintain these layers 11, 12 in square.

With reference to FIG. 2, the pool 1 incorporates a dismount / descent system 4 which is designed to vertically move a mobile underfloor 5 (described later) between a low immersed position and a raised upper position.

This up / down system 4 comprises several lifting pillars 40 arranged between transverse joists 21 of the bottom structure 2. In the example shown, the up / down system 4 comprisesix lifting pillars 40 intended to be fixed at different points under the baseplate 5 , being indicated that the number and positioning of the lifting pillars 40 will depend essentially on the dimensions and shapes of the basin 1 and the floor 5.

Each lifting pillar 40 is formed of an impervious and non-elastic envelope, in particular of an envelope comprising at least one layer of woven and sealed material, and comprises a water inlet 41 preferably located at its base or in the lower part.

Each lifting pillar 40 is provided with at least one upper fixation member for fixing under the floor 5, in order to fix the lifting pillar 40 under the floor 5. In the example of FIG. 7, the lifting pillar 40 comprises at its top ( or in the upper part) several straps 42forming such upper fasteners.

Each lifting pillar 40 is provided with at least one lower fixation member for attachment to the bottom structure 2, in order to fix the elevator riser 40 on this bottom structure 2. In the example of FIG. 7, the lifting pillar 40 comprises at its base (or in the lower part) severalangles 43 forming such lower fasteners.

With reference to FIGS. 2 and 3, the up / down system 4 also comprises a hydraulic system 7 connected, on the one hand, to the water inlets 41 of the lifting pillars 40 and, on the other hand, to the basin 10, where the hydraulic system 7 is configured to circulate the water in two directions: - a filling direction in which the water flows from the basin 10 to the elevator boats 40 for a filling of their envelopes in water to ensure a rise of the floor 5; and - a dump direction in which the water flows from the lifting pillars 40 to the basin 10 for emptying their envelopes in water to ensure a descent of the floor 5.

With reference to FIGS. 2 and 3, this hydraulic system 7 includes a pump 70 connected to: - the water inlets 41 of the lifting pillars 40 via a first pipe 71; and - to the basin 10 via a second pipe 72.

With reference to FIG. 8, the first duct 71 can be connected to an inlet of a common water collector 73, where this common water collector 73 has a plurality of outlets 74 connected to the lifting pillars 40 by distribution ducts 75.

These distribution pipes 75 may be provided with vannestarées and / or have the same lengths and diameters, to ensure an equivalent water filling rate between the various lifting pillars40. These distribution lines 75 may be, by way of non-limiting example, flexible pipes with a diameter of 32 millimeters, while the first channel 71 and the second pipe 72 may be flexible ledges of diameter 64 millimeters. The diameters of the distribution conduits 75 and the first and second lines 71, 72 will preferably be based on the dimensions of the lift pillars 40 and the desired time to move the floor 5 from the low position to the high position.

To ensure the filling and emptying of the lifting pillars 40, this hydraulic system can comprise: either a reversible pump (or pump with two directions of circulation) controlled; or a non-reversible pump associated with a system of controlled valves (such as solenoid valves) which controls an inversion of water circulation at the inlet of the pump.

The pump 70 may for example consist of a countercurrent denuder pump which is connected, via a dispensing valve (not illustrated), both to the lifting pillars 40 and to a swimming mouth (not illustrated) opening into the basin 10 to provide a counter-current swim function, this dispensing valve being operable (such as for example a controlled valve or solenoid valve) for distributing the water either in the direction of the lifting pillars 40 or towards the swimming mouth, depending on the desired use that is, raising the floor 5 or swimming against the current.

With reference to FIGS. 2 and 3, the up / down system 4 also comprises a control system 8 which comprises a control module 80 (such as a processor or electronic controller) which controls the hydraulic system 7 to control the circulation of the water in either of the two directions of flow and thus to control the rise / fall of the floor 5.

Thus, this control module 80 controls: - either the controlled reversible pump; - the system of controlled valves.

This control system 8 may also comprise at least one high detection system 81, 82 configured to detect the floor 5 in a high position, where this high detection system 81, 82 is connected to the control module 80 which controls the hydraulic system 7 in function. detection detected by this high detection system 81, 82.

With reference to FIGS. 2 and 3, the detection system comprises an optical or mechanical position sensor 81 disposed on the base 10, and more specifically on the supporting structure 3 at the top, as for example on the upper frame 32 or on the coping 33.

Alternatively or additionally, the top detection system comprises a pressure sensor 82 configured to detect whether the pressure in the elevator pillars 40 reaches a predefined high value. Indeed, when the floor 5 is in the upper position, resting against the lip 33, the pressure in the lifting pillars 40 increases to reach this high value. This pressure sensor 83 may for example be placed on the first channel 71 or on the second pipe 72.

Thus, during the rise of the floor 5, the control module 80controls the hydraulic system 7 for a flow of water in the filling direction, until the upper detection system 81, 82 detects the high position of the floor 5, as for example until the position sensor 81 detects the floor 5 in the high position and / or until the pressure sensor 82 detects the high value associated with this top position of the floor 5.

This control system 8 can also comprise at least a low detection system 83 configured to detect the floor 5 in low position, where this low detection system 83 is connected to the control module 80 which controls the hydraulic system 7 according to the detection performed by this low detection system 83.

With reference to FIGS. 2 and 3, the detection system comprises an optical or mechanical position sensor 83 disposed on the base 10, and more specifically on the supporting structure 3 at the bottom, as for example on the lower frame 32 or on the structure carrier 2.

Thus, during the descent of the floor 5, the control module80 controls the hydraulic system 7 for a flow of water according to emptying theens, until the bottom detection system 83 detects the low position of the floor 5.

With reference to FIG. 2, each lifting pillar 40 can occupy a retracted configuration in which the envelope (or the lifting pillar) is flushed with water in order to allow the floor 5 to be in the low immersed position.

With reference to FIG. 3, each lifting pillar 40 may occupy an expanded configuration in which the envelope (or the lifting pillar) is filled with water from the basin 10 (thanks to the pump) in order to support the floor 5 in the raised up position.

Referring to Figure 6, the floor 5 comprises: - a support structure 50 of wood which is composed of transverse beams 51 and longitudinal beams 52 intersecting and fixed between them, and - a platform consisting of a fixed blade assembly 53 on the support structure 5, for example between the transverse beams 51.

The transverse beams 51, the longitudinal beams 52 and the blades 53 are made of wood, and are fixed together by screwing or bolting, possibly with the use of brackets or brackets.

So that the floor 5 is not floating, it is expected that the floor5 also incorporates at least weighting element (not shown).

This weighting element can be fixed on the support structure 50, below the blades 53. The or each ballast element may for example be a concrete plate.

As a variant or in addition, the weighting elements may be made in the form of traffic slabs, such as fibered concrete slabs or tiled slabs fixed (especially by gluing) on the slats 53. These slabs of circulation constitute decorative elements filling a role of support to the circulation on the floor.

It should be noted that the platform could be composed of these traffic halls fixed directly on the support structure 5, instead of place blades 53, which would make it possible to dispense with element of the complementary stage.

The floor 5 can also incorporate an access hatch (not illustrated) to be able to pass below the floor 5 and thus perform maintenance operations.

Each lifting pillar 40 is fixed under the floor 5, and more specifically is fixed on the support structure 50, below the blades 53. At the installation, the floor 5 is placed inside the basin 10 on the bottom structure 2, so that the floor 5 rests freely on the bottom structure 2 in the low submerged position illustrated in Figure 4, with the lifting pillars 40 in retracted configuration. When the floor 5 is in the low submerged position, the pillars 40 are compressed and occupy an interstitial space between the floor 5 and the sealing layer 11.

During the water filling of the lifting pillars 40, the lifting pillars 40 move from the retracted configuration to the deployed configuration, and thus the lifting pillars 40 raise the floor 5 to the raised position shown in FIG. 5.

During this rise of the floor 5, guiding devices 6 fixed to the floor 5 guide the rise of the floor 5. As shown in Figure 9, the floor 5 supports a plurality of guiding devices 6 provided with rolling members 60 shaped to roll along Some of the vertical posts 34 during the vertical displacements of the floor 5. Each guiding device 6 also comprises an elastic member 61, in particular of the helical spring type, able to urge the rolling member 60 against the side panel 35 concerned. The rolling members 60 may be in the form of rollers or balls.

These guiding devices 6 are fixed on the support structure 50, below the blades 53.

Once the floor 5 in the raised up position, the lifting pillars 40 support the floor 5 in the raised up position, thanks to the incompressible nature of the water, being noted that the water present in the lift boats 40 remains in the lifting pillars 40 to means either an independent valve placed upstream of the pump, or a valve presentdirectly in the pump.

As shown in Figure 9, the lip 33 forms a stopper for the floor 5 in its raised upper position. Thus, the lip 33 stops the floor 5 and ensures a horizontal leveling of the floor with this peripheral device of the floor 5 on the lip 33. It should be noted that lamargelle 33 will be placed on the upper frame 32 after installation duplicate 5 on the bottom structure 2.

In an advantageous embodiment, the pool 1 incorporates floor lifting levers 5 which can be placed when the floor 5 is in the raised position and thus secure the floor 5 in this position once the pool emptied of its water. Such crutches will also purge the up / down system 4 of its water, for a technical intervention, while keeping the floor 5 in the up position

It is also conceivable, alternatively or in addition to these lifting crutches, to keep the lifting pillars 40 filled with water, which allows to keep the floor 5 in the high position despite the emptying of the pool.

In the example illustrated in the figures, it is expected that the up / down system 4 comprises a single series of lifting pillars 40 each having the same height H max in deployed configuration, so that the up / down system 4 is designed to move vertically 5 between the low immersed position and the raised up position, and to maintain the floor 5 in its high position.

During this rise from the low immersed position to the high emerged position, the balancing of the lifting pillars 40 isnaturally by the phenomenon of communicating vessels.

The lifting pillars 40 (their numbers, their dimensions and theirconfigurations) and the floor 5 are configured so that the chargeable on the floor 5, once in high position, is at least 150 kilograms per square meter.

By making sure that each lifting pillar 40 receives a flow rate and an equivalent amount of water, in an equivalent time, it is envisaged not to completely fill the lifting pillars 40 (for example semi-filling), so that these pillars 40 may move the floor 5 between the low immersed position and an intermediate position between the immersed low position and the highemerged position, and such lift pillars 40 will support the floor 5 in this intermediate position. Such an intermediate position can be envisaged so that the pool 10 offers a reduced depth, so for example that the pool is accessible for children not able to swim.

In a particular embodiment and not illustrated, it can be expected that the up / down system comprises: - a first series of lifting pillars each having the same first height Hmax deployed configuration, so that the raising pillars of the first series can support the floor 5 in the raised position; and a second series of lifting pillars each having the same height Hint in the deployed configuration, this second height being smaller than the first height Hmax, so that these lifting pillars of the second series can support the floor in an intermediate position between the submerged low position. and the high position emerged.

Thus, this up / down system is shaped to position the floor 5: - either in the low submerged position, so that the basin offers its maximum depth; either in the intermediate position under the action of the only lift pillars of the second series, so that the basin has a reduced depth, for example that the pool is accessible for children not able to swim (in the manner of a paddling pool) ; - either in the high position emerging under the action of the only lifting pillars of the first series, so that the basin is covered.
