Description

Title of the invention: Assembly comprising a basin and a basin covering device.

[0001] The present invention relates to the field of basins and covers for such basins.

[0002] BACKGROUND OF THE INVENTION

[0003] For the storage of materials, for example more or less fluid agricultural materials, such as slurry, it is known to use large basins.

[0004] Such basins have lengths and widths greater than several tens of meters, sometimes of the order of one to several hundred meters.

[0005] With such a large pond area, it is common to seek to limit the supply of rainwater to the pond.

[0006] For this, it is known to have a device for covering the pool comprising one or more tarpaulins stretched over the pool.

[0007] The risks of degradation / dilution of the material contained in the basin and of accidental overflow of the basin are thus minimized.

[0008] However, pockets of rainwater regularly form on the upper face of the tarpaulin and it is then necessary to evacuate the water using pumping conduits or using pumps which are arranged above the tarpaulin.

[0009] The pumping lines and / or pumps must be regularly checked and repositioned to ensure that any pockets of water present on the tank are correctly evacuated.

[0010] Monitoring / maintenance of pipes and pumps is essential to preserve the liner, the pool and the material contained in the pool.

[0011] In addition, any intervention on the pool requires the prior removal of the pipes / pumps to free the cover and thus access the internal volume of the pool.

[0012] Interventions on pipes and pumps can also cause damage to the tank(s), which increases maintenance time and the operating cost of the whole.

[0013] SUBJECT OF THE INVENTION

[0014] An object of the present invention is therefore to provide an assembly comprising a pool and a device for covering the pool resolving all or part of the aforementioned drawbacks of the prior art. Summary of the invention

[0015] To this end, the invention essentially relates to an assembly comprising a basin having a peripheral external edge of the basin and a basin covering device, the covering device comprising: - a plurality of cables, each given cable of the plurality of cables being stretched between first and second portions of the given cable; and - at least one cover tarpaulin supported by at least some of the cables of the plurality of cables to define a cover surface arranged above the pool.

[0016] The assembly according to the invention is essentially characterized in that the device comprises a support arranged in the basin to support said plurality of cables above the basin and to generate at least one slope of said at least one cover such that water located on an upper face of said at least one cover flows from the support towards an area external to the basin, passing above the peripheral external edge of the basin.

[0017] Such a support positioned in the basin is particularly advantageous because it allows: - to support the cables which carry the tarpaulin (by absorbing vertical forces exerted by the cables stretched on the support); and - to create a slope on the upper face of the liner to guide a flow of water on the liner going from the support towards the outside of the pool.

[0018] This prevents the formation of pockets of water on said at least one tarpaulin and eliminates the need to position pipes or pumps to collect water present on the upper face of the tarpaulin.

[0019] Preferably, the covering device comprises at least one agitator which comprises stirring blades and at least one motor for moving the blades in the basin (around an axis of rotation X of the agitator) and for agitating a fluid material contained in the basin.

[0020] Said at least one agitator is carried by said support.

[0021] In many applications, the material stored in the basin must be agitated to maintain its homogeneity (the agitator limits the risk of sedimentation of the material or the risk of formation of a skin or dry aggregates on the surface).

[0022] Preferably, the fluid material M contained in the basin 1 is here slurry which must be regularly mixed to avoid the formation of solidified aggregates which are difficult to remove from the basin.

[0023] The fact that the support carrying the cables of the cover device also supports the agitator makes it easier to position the agitator in the pool since the cables contribute to the stability of the support and consequently to the stability of the agitator relative to the edge of the pool, the agitator being able to be easily centered in the pool.

[0024] It should be noted that the blades can be fully arranged in a space formed between uprights of the support, these uprights forming a protection to avoid a accidental contact with the blades. Brief description of the drawings

[0025] Other characteristics and advantages of the invention will emerge clearly from the description given below, for information purposes only and in no way limiting, with reference to the appended drawings, in which:

[0033] [Fig.6] [Fig.6] is a top view of the assembly 0 similar to that illustrated in [Fig.2], the only difference being that the basin 1 is here circular in shape instead of rectangular in shape, the support 4, seen from above, is here rectangular in shape, the guides 41 arranged on the support 4 making it possible to position and guide the cables 2a above the basin 1 while the fasteners 6 arranged along the external edge 1a of the basin 1 make it possible to stretch each cable 2a between the edge of the basin and the support 4 to carry one or more tarpaulins above the basin while creating the slopes of tarpaulin(s) going down from the support 4 to the external edge 1a. DETAILED DESCRIPTION OF THE INVENTION

[0034] As indicated previously, the invention relates to an assembly 0 comprising a basin 1 having a peripheral external edge 1a and a covering device 2 for the basin 1.

[0035] As understood from Figures 1 and 2, the covering device 2 comprises: - a plurality of cables 2a, each given cable 2a of the plurality of cables 2a being stretched between first and second parts 2a1, 2a2 of the given cable 2a; and - at least one cover tarpaulin 3 (illustrated in dotted lines in [Fig.l]) supported by at least some of the cables 2a of the plurality of cables to define a cover surface arranged above the pool 1.

[0036] The device 2 comprises: - a support 4 arranged in the basin 2 to support said plurality of cables 2a above the basin 2 and to generate at least one slope of said at least one cover such that water located on an upper face of said at least one cover 3 flows from the support 4 towards an area external to the basin, passing above the peripheral external edge 1a of the basin 1.

[0037] The tarpaulin is preferably waterproof, for this purpose, the tarpaulin 3 can be made of PVC or HDPE.

[0038] Preferably, each tarpaulin is also gas-tight, which is particularly useful for applications where it is desired to collect gases released by the material M contained in the basin.

[0039] The basin 1 comprises a sealing membrane extending continuously at the bottom of the basin.

[0040] This basin 1 can be created by digging the ground and / or by constructing an external edge 1a peripheral to the basin, this external edge 1a extending above a ground level.

[0041] In top view, the shape and dimensions of the outer edge 1a of the basin 1 may vary depending on the need. For example, the basin may be rectangular, as in the example of [Fig.2], or it may be circular, as in the example of [Fig.6].

[0042] The shapes of the basin are in no way limiting because the set of cables arranged between the support 4 and the external edge of the basin where the cables are attached (via fasteners 6) makes it possible to cover a wide variety of basin shapes.

[0043] The support 4 can simply be placed on the bottom of the pool, the sealing membrane preferably extending under one or more feet of the support 4, which promotes the sealing of the pool while simplifying the installation of the support 4 in the pool 1.

[0044] Alternatively, it is also possible to create a waterproof base of the support against which the waterproofing membrane is connected to the waterproofing by going up along and all around this base of the support.

[0045] The support 4 here forms a ridge of the covering device 2 of the pool 1, this covering device 2 comprising at least two sides or, as in the present case, four sides.

[0046] At least one of the sides is covered, at least in part, by the tarpaulin 3 to create a downward slope extending from the support 4 towards the external edge 1a of the basin 1.

[0047] The covering device 2 may comprise one or more tarpaulins 3 to define the downward covering slopes, the device 2 covering the entirety of the pool 1. These tarpaulins may be connected to each other by watertight and possibly gastight assembly means, such as welds or gluing of tarpaulin junctions.

[0048] As indicated previously, said covering device 2 preferably comprises at least one agitator 5.

[0049] In this case, in the example illustrated in figures 1 and 2, the device comprises four agitators 5 for agitating the material M located in the basin, in this case slurry.

[0050] Each agitator 5 comprises stirring blades 5a and at least one motor 5b for moving the blades 5a in the basin 1 and stirring a fluid material M there. These blades of an agitator 5 are here moved around an axis of rotation X of the agitator.

[0051] The axes of rotation X are here vertical but it is also possible that each axis of rotation X has its own orientation (vertical or inclined) to generate a particular flow of the material M in the basin 1.

[0052] Said fluid material M contained in the basin 1 is here slurry which must be regularly mixed to avoid the formation of solidified aggregates which are difficult to remove from the basin 1.

[0053] The number, the arrangement of the agitators 5 and the geometry of the blades are chosen according to the geometry of the basin to promote a movement of material M over the entire basin. This avoids the formation of crusts that are difficult to collect.

[0054] Preferably, each motorization 5b is placed above an upper plane Basin ps 1 in which an upper face of the peripheral external edge 1a of basin 1 extends.

[0055] Preferably, each of the blades 5a of the agitator 5 extends exclusively between a bottom of the basin 1 and said upper plane Ps of the basin 1 (this limits the risk of material being projected).

[0056] The positioning of the motorization 5b above the upper plane Ps of the basin 1 makes it possible to keep the motorization 5b away from the fluid material M.

[0057] This limits the risk of damage to the motorization 5b.

[0058] Here, each motorization 5b comprises at least one electric motor and possibly actually a geared motor.

[0059] Set 0 may also include: - a control device arranged to control the operation of the motor, to activate the movement of the blades in the basin and possibly to vary the speed of rotation of the blades; and - a pump designed to evacuate fluid material M located in the basin.

[0060] The support 4 is here a tower having a base placed at the bottom of the basin 1 and having a top carrying each of said cables 2a of said plurality of cables 2a.

[0061] Preferably, the tower forming the support 4 comprises several uprights 4a extending in substantially vertical directions.

[0062] These uprights are here parallel to each other but they could be inclined relative to each other so that these uprights are closer to each other at the top of the tower than they are at its base.

[0063] The uprights 4a are preferably connected to each other by crosspieces and bracing links of the tower.

[0064] The motorization of the agitator 5 is preferably arranged between several of these uprights 4a of the tower which makes it possible to protect it against shocks.

[0065] In the case illustrated in Figures 1 and 2, the tower comprises at least four vertical uprights 4a, in this case ten parallel uprights 4a.

[0066] Each motorization 5b of a given agitator is located between four external uprights of the tower which are associated with it.

[0067] Each motorization 5b is preferably arranged equidistant from these associated uprights.

[0068] In this way, the forces generated by the motorization on the support are distributed equally between the uprights, which improves the stability of the covering device during operation of the agitator.

[0069] As the cables 2a are taut and pass over the support 4, they contribute to stabilizing the support, both vertically and laterally (the cables oppose the tilting of the support 4).

[0070] In summary, thanks to the invention, it is possible to install one or more agitators 5 carried by the same support 4 which is securely held / secured in the basin.

[0071] This securing of the support 4 by the cables 2a makes it possible to install several agitators 5 without risk of damage to the basin or the covering device (the risk of accidental contact between the agitation blades 5a and the basin is minimized).

[0072] In the example of [Fig.2], four agitators 5 are carried by the tower and are shown diagrammatically in dotted lines.

[0073] As can be understood in particular in figures 2 to 4b, the support 4 preferably comprises a plurality of guides 41.

[0074] Each cable 2a of the plurality of cables 2a bears laterally against at least one guide 41 which corresponds to it and which belongs to said plurality of guides 41.

[0075] The guides 41 are arranged to keep the cables 2a spaced apart from each other.

[0076] Preferably, as illustrated in [Fig.4b], at least some of the guides 41 comprise a sliding part 41b provided with a groove 41bl.

[0077] Each given cable 2a bearing laterally against a lateral guide 41 which corresponds to it passes through a groove 41bl of the sliding part 41b corresponding to the given cable.

[0078] The cables 2a of the plurality of cables are distributed between at least first and second groups of cables G1, G2.

[0079] The guides 41 of the plurality of guides are arranged on the support 4 in such a way that the cables 2a of the first group Gl move away from each other going from said support 4 towards the peripheral external edge 1a of the basin 1.

[0080] The guides 41 are arranged on the support 4 so that the cables of the second group G2 are parallel to each other.

[0081] The plurality of cables also comprises a third group G3 of cables 2a distinct from the cables belonging to the first and second groups Gl, G2.

[0082] The guides 41 of the plurality of guides are here arranged on the support 4 in such a way that the cables 2a of the third group G3 move away from each other going from said support 4 towards the peripheral external edge of the basin 1.

[0083] Thus, the first group of cables Gl consists of the cables arranged at a first of the longitudinal ends of the support 4 observed in top view.

[0084] The cables of the first group Gl form a support for the tarpaulin radiating from the first longitudinal end of the support 4 to a part of the peripheral external edge 1a of the basin 1 opposite this first longitudinal end of the support 4.

[0085] The second group G2 is preferably made up of the cables arranged between the two longitudinal ends of the support 4, that is to say the cables which, when viewed from above the pool 1, extend along the width of the pool.

[0086] Above the support 4, the cables of the second group G2 are parallel to each other.

[0087] The third group of cables G3 is preferably made up of cables arranged one second from the longitudinal ends of the support 4 observed in top view.

[0088] These cables of the third group G3 form a support for the tarpaulin radiating from the second longitudinal end of the support 4 to a part of the peripheral external edge 1a of the basin 1 opposite the second longitudinal end of the support 4.

[0089] Thus, in top view, the first and third groups of radiating cables G1, G3 respectively make it possible to support the tarpaulin(s) along the first and second longitudinal ends of the support 4.

[0090] The second group of parallel cables G2 makes it possible to support the tarpaulin(s) along the longitudinal edges of the support 4 up to at least one of the longitudinal edges of the pool.

[0091] These groups of cables G1, G2, G3 form regularly spaced tarpaulin supports (all around the support 4) to support the tarpaulin(s) extending all around the support 4 up to at least the level of the peripheral edge 1a of the pool 1 so as to cover the entire pool with the tarpaulin(s).

[0092] With this arrangement of the cable groups G1, G2, G3, it is possible to cover, with a single support 4 centered in the basin, a variety of types of basins of different geometries, more or less long, more or less wide.

[0093] It should be noted that the support 4 may have at least one upper beam extending above the basin, extending on either side of the tower.

[0094] Said guides 41 can be carried on said at least one upper beam.

[0095] In this way, it is possible, without having to increase the dimensions of the tower, to cover a larger pool since the upper beam(s) extend beyond the tower to support at least some of the cables of the plurality of cables.

[0096] It is also conceivable that the support comprises several towers between which extend the said upper beam(s) of the support which support the cables.

[0097] As can be seen in particular in FIGS. 3, 4a and 4b, the guides 41 are distributed so as to form first and second alignments of guides.

[0098] The guides of the first alignment L1 of guides 41 are arranged along a first upper side of said support 4 (possibly along a first upper beam) and the guides of the second alignment of guides 41 are arranged along a second upper side of said support 4 (possibly along the first beam or on a second beam parallel to the first beam of the support).

[0099] In the present case, each given guide 41 comprises a sliding part 41b fixed around a fixed vertical axis 41x associated with the given sliding part 41b.

[0100] Each fixed axis 41x is fixedly mounted relative to said support 4.

[0101] In this way, the cables 2a are guided relative to the support 4 thanks to the parts sliding 41b (each sliding part is circular 41b and centered around an axis 41x which corresponds to it and which is fixed relative to the support 4).

[0102] As illustrated in [Fig.4b], each given sliding piece 41b has a hollow profile 41bl in which a cable 2a associated with the given sliding piece is received.

[0103] Preferably, the sliding pieces 41b are spaced from each other so that sliding pieces adjacent to each other together form a narrow space for holding a cable between the support 4 and at least one upper edge of the adjacent sliding pieces 41b.

[0104] Two adjacent sliding pieces 41b are shaped to have a cable passage space between adjacent sliding pieces 41b which is greater than the diameter of the cable passing between these adjacent pieces.

[0105] For example, the spacing between two adjacent sliding pieces could be 11 mm for a 9 mm diameter cable.

[0106] As illustrated in [Fig.4b], the narrow space between two adjacent sliding pieces 41b makes it possible to oppose the movement of the cable 2a in a direction parallel to the fixed axis of sliding piece 41x.

[0107] Thus, the risk of the cable 2a being torn off in the event of a strong gust of wind is largely minimized thanks to the hollow profiles 41bl of the sliding pieces and the distance between the adjacent sliding pieces.

[0108] In this way, each given cable is held between two adjacent sliding pieces and the only movement allowed for this cable is a tangential movement to the adjacent sliding pieces.

[0109] Although this is not the case here, at least some of the sliding parts could be pulleys each mounted to rotate around a corresponding fixed axis 41x.

[0110] As understood from Figures 1 to 3, each first part 2a 1 of given cable 2a is fixed on a first corresponding fastener 6 to said given cable 2a.

[0111] Similarly, each second part 2a2 of said given cable 2a is fixed to a second attachment corresponding to said given cable 2a.

[0112] Each of the fasteners 6 is fixedly connected relative to the peripheral external edge 1a of the basin 1.

[0113] Preferably, the fasteners 6 are regularly arranged along the external edge of the basin 1, for example 50 cm from each other.

[0114] Different forms of fasteners 6 are conceivable for implementing the invention.

[0115] In the present case, each given attachment 6 comprises a tube 60 for the passage of cable 2a around the tube 60 (or possibly in the tube) and at least one fixing axis 61 fixed in said peripheral external edge 1a of the basin 1.

[0116] Spacers 62, in this case nuts 62, are arranged between the tube 60 and the upper face of the external edge of the basin to create a cable passage space 2a between the tube 60 and the external edge of the basin.

[0117] Here, each spacer 62 is formed by a nut screwed around a complementary threaded portion of one of the corresponding fixing axes 61.

[0118] Thus, each tube 60 allows the passage of a cable 2a between the edge of the pool and the tube 60 to guide it and position it relative to the edge of the pool 1.

[0119] A cable 2a positioned by a clip 6 can be tensioned by sliding it relative to the tube 60 of the clip 6.

[0120] In this way, each attachment has the form of a mooring cleat around which the cable(s) can pass.

[0121] Locking means may be associated with the cable to keep it in tension with respect to the attachment 6.

[0122] A locking means could comprise a knot formed with the cable and / or one or more cable clamps (for example stainless steel cable clamps).

[0123] For example, the cable clamp(s) could be arranged to clamp against each other portions of the same cable which passes around the attachment 6 (for example, the cable can pass around the tube 60 of the attachment 6 by making a half-turn, one turn or several turns).

[0124] The two portions of the cable can thus be clamped against each other by one or more cable clamps arranged in series on the cable to compress portions of the cable against each other and to oppose the relative sliding of these portions of the cable against each other. Other locking means can be envisaged to hold the cable on the given attachment 6.

[0125] For example, one could envisage that the cable is simply blocked on the attachment 6 by making several dead turns around the tube 60 with the cable (for example three dead turns or more) then a blocking knot as is practiced in the navy to block a mooring line on a mooring cleat.

[0126] In the present case, as illustrated in Figures 5a, 5b, the tube 60 of the attachment 6 is held stationary relative to the peripheral external edge 1a of the basin 1 via two fixing axes 61 also called anchor rods which are sealed in the peripheral external edge 1a.

[0127] The peripheral outer edge of the basin 1 comprises several stringers arranged end to end to define the peripheral outer edge of the basin.

[0128] Here, each stringer has first and second longitudinal ends. forming the ends of the stringers, these stringers being able to be reinforced concrete molded parts.

[0129] Each given fixing rod / axis 61 is for example fixed in one of the stringers which corresponds to it, either by sealing, or by molding the stringer around the fixing rod.

[0130] In this configuration, each cable 2a can pass between the fixing axes 61 of the corresponding attachment while sliding in a space formed between the tube and an upper face of the edge of the pool (here constituted by stringers).

[0131] As illustrated in Figures 2, 3 and 4a, each cable 2a comprises a central portion resting on said support 4 so that the central portion of the cable is held above a central zone of the basin 1.

[0132] In top view, the central area of ​​the basin is inside the perimeter delimited by the peripheral outer edge 1a of the basin 1.

[0133] As indicated previously, the support 4 is here a tower fixedly arranged on the central zone of the basin.

[0134] In the present case, the basin 1 has four parallel sides two by two which together constitute said peripheral external edge 1a of the basin 1 which is here rectangular in shape.

[0135] More particularly, the central portions of the cables 2a are supported on an upper part of the support 4, in this case, on an upper plate extending horizontally to form a top of the support.

[0136] The majority of the central portions of the cables 2a which are on the support 4 extend parallel to each other which limits the friction between cables.

[0137] This is for example the case of the cables 2a of said second group of cables G2 illustrated in [Fig.2] of which central portions located above the support 4 are all parallel to each other.

[0138] At least some of the cables 2a of the plurality of cables extend from one of said sides of the basin to another of said sides of the basin, which makes it possible to balance the forces exerted on either side of the support 4.

[0139] Certain cables of the first group of cables G1, like certain cables of the third group of cables G3, may have their respective first and second parts 2a1, 2a2 arranged at the same side of the edge of the basin 1 to which they are attached.

[0140] Thanks to the sliding parts 41b, the tensions exerted on either side of the support 4 by the cables 2a of the first and third groups G1, G3 are balanced, which limits the risk of the support tipping over.

[0141] Finally, as shown diagrammatically in [Fig.l], said at least one tarpaulin 3 is impervious to the passage of methane and is hermetically connected to said peripheral external edge of the basin 1 so as to form between basin 1 and the tank(s) 3, a gas containment enclosure E.

[0142] At least one gas outlet tube T is hermetically connected to said enclosure E to collect gases therein.

[0143] In the case where the material M contained in the basin is of a fermentable nature, such as slurry, a release of gas is obtained in the enclosure E which contains methane.

[0144] The invention makes it possible to equip pre-existing slurry storage basins 1 with a methane collection function.

[0145] This is all the more interesting since the majority of slurry storage basins do not have such a capacity.

[0146] The gas outlet tube T, shown diagrammatically in [Fig. 1], may be a tube with a diameter of between 50 mm and 200 mm, preferably a tube with a diameter of 100 mm.

[0147] This tube T can be connected to a gas distribution network external to the assembly 0 or to a gas storage tank, this connection being able to be made either directly or via a pump and / or a compressor and / or a gas treatment installation.

[0148] A gas treatment plant may be adapted to separate gases from the enclosure into a methane stream and a stream of other gases such as sulfur gases.

[0149] This network and / or the tank can be connected to an industrial or agricultural installation or to one or more dwellings to, for example, supply gas-consuming appliances (such as gas combustion appliances such as boilers and / or a fuel cell).

[0150] Said at least one gas outlet tube T can be hermetically connected: - at the tarpaulin 3 at the level of a gas passage formed through the tarpaulin; or - connected to an upper plate of the support carrying a connector passing through this upper plate of the support, the tube then being connected to the enclosure via this connector carried by the plate of the support; or - connected to a connector fixed on the external edge of the basin.

[0151] The connection between the tube T and the enclosure E can be movable relative to the basin when the latter is carried by the cover.

[0152] This can be useful for equipping a pre-existing basin with a methane capture capacity by modifying only the tank.

[0153] The connection between the tube T and the enclosure E can be fixed relative to the basin 1 when this connection is carried by the upper plate of the support 4 or when it is fixed to the edge of the basin 1.

[0154] The advantage of having the tube T connected to the enclosure E via an upper plate of the support 4 is to provide a support equipped with its own means of collecting the methane gas, which avoids having to modify the tarpaulin or the basin to assemble the tube there.

[0155] A disadvantage of this solution is that it involves having the tube T extending over at least half the width of the basin 1, above the cover 3, which complicates the operations of installation and maintenance of the tube / enclosure connection.

[0156] The advantage of having the tube T connected to the enclosure via a fixed connection at the external peripheral edge of the basin is to avoid the need for modification of the support 4 or the cover 3.

[0157] It is also advantageous to position the connection between the tube and the enclosure close to the external edge of the basin to make it more accessible and easier to maintain.
