Definitions
- the present invention relates to improvements brought to the water collecting devices (skimmers) at the surface of a basin, intended for a pumping, in particular to supply an installation of filtration of pond water, and it concerns more particularly the improvements made to those of these devices which are of the floating type.
- the skimmers usually used in conjunction with water basins such as swimming pools are maintained at a correct level, relative to the surface of the water in the pelvis, being joined, possibly so adjustable, to a fixed element of the basin (e.g. wall, ladder, etc.).
- the water level in the skimmer body varies in particular depending on the flow pump suction and disturbances affecting the entry of water into the skimmer body (for example fouling of the coarse filter basket, blocking of the bowl floating above water level, etc.).
- the invention therefore aims to remedy this disadvantage and to propose an improved arrangement for such a floating device such that even in the case of a reduction or interruption of the arrival of water by gravity in the skimmer body, the pump does not cannot be defused and jointly in such a way that the improved device remains of a simple structure and made up of parts that are easy and inexpensive to manufacture, at the same time as the operation of the device does requires no intervention to switch from another functional configuration in normal situation at a functional configuration in abnormal situation or degraded.
- the base includes an annular plate through which engages freely a connector for connecting the skimmer body to the pumping means, a free space remaining between said end cap and the inner edge of the annular plate for the backwater from the basin during operation of the device in an abnormal situation. It is then possible to do so that the base further comprises at least one member protruding radially inward from the periphery of the annular plate to constitute a stop for vertical retention of the skimmer body; he is interesting that the projecting member is an annular wing and that the base has, in cross section, a shape in [.
- skimmer body when the skimmer body is made of a low density material, for example in low density plastic material, skimmer body can be fitted with a ballast so that its density becomes significantly greater than 1.
- FIGS. 1 and 2 schematically represent, in section, a preferred embodiment of a device arranged in accordance with the invention and shown respectively in two different functional situations.
- FIG. 1 it is depicted a floating water collection device at the free surface of a basin such as a swimming pool, in particular to supply a water filtration system to the pool.
- a floating water collection device at the free surface of a basin such as a swimming pool, in particular to supply a water filtration system to the pool.
- Such devices are usually referred to as skimmers or include a skimmer.
- the device illustrated in Figure 1 includes a floating support 1 arranged as a whole anyway suitable for floating on the surface of the pool (choice of the constituent material; presence of one or more floats 2 of material having a density substantially less than 1, for example in foam).
- the floating support 1 has a clean base 3 to support, in said support 1, a skimmer designated in as a whole by the numerical reference 4.
- the skimmer 4 includes a shaped skimmer body 5 box open up. On the upper edge of the skimmer body rests, in general, a screen 6 intended to retain coarse debris (sheets, papers, branches, ).
- the skimmer body 5 has a bottom 7 provided centrally from a main orifice giving access to a end piece 9 for fixing a flexible pipe 10 for connection to pumping and filtration means (not shown) normally located outside the pool.
- the bottom 7 of the skimmer body 5 is provided one or more auxiliary passages 11 arranged between the main orifice 8 and the peripheral edge.
- the skimmer body is constructed so as to have a density close to, but significantly higher to 1, so that it is naturally "flowing". he can be made of a material suitable for this purpose, or well, being made of a material of density substantially less than 1, it can be ballasted, for example using a heavy ring 12 which, in the embodiment illustrated, rests on its bottom and hugs its interior outline as shown in figure 1.
- the skimmer body 5 is capped with a bowl 13 having a density slightly less than 1 and therefore naturally "floating".
- the floating bowl 13 can be made up of a material of density slightly less than 1 or, being made of a material with a density greater than 1, be provided with flotation means such as a foam ring as illustrated in fig. 1.
- This bowl 13 has above an axial opening 14 constituting the water inlet of the skimmer.
- the aforementioned base 3 has an annular plate 15 located under the bottom of the skimmer and provided with a central recess 16 through which is engaged the end piece 9 secured to the bottom 7 of the skimmer body.
- a free space 16 a remains between the edges of the recess 16 and the end piece 9 passing through it.
- an organ inwardly directed radial extent stopper intended to limit the amplitude of the vertical movement of the body of skimmer 5 above the annular plate 15.
- the stop member 17 is a parallel annular wing to the plate 15 and joined to the latter by a vertical skirt 18, so that the base has, in cross section, a form in [.
- a radial projection 17 a is provided on the skimmer body 5 which can, for example, be peripheral and be constituted by a peripheral zone of the bottom 7 projecting beyond the wall side of the skimmer body 5.
- the operation of the device is as follows.
- the floating bowl 13 In normal functional situation (see fig. 1), the floating bowl 13 is located immediately below the surface free of water from basin 19, balanced under the different forces to which it is subject. The floating bowl can thus follow slow variations of the free surface 19, letting a flow in the skimmer body lamellar water causing, by surface effect, the debris floating on the free surface 19.
- the skimmer body In this normal functional situation, the skimmer body is "flowing" and rests on the pan annular 15 of the base 3, which is itself supported at a predetermined distance below the free level 19 thanks to the floats 2 of the support 1. In this position, the auxiliary passages 11 made in the bottom of the body of skimmer 5 are closed by the annular plate 15 of the base 3.
- the almost empty skimmer body becomes "floating" and lifts above the annular plate 15 up to abut against the annular retaining wing 17, in causing the floating bowl whose upper edge passes over of the free surface 29.
- auxiliary passage (s) 16 are released and the water from the basin penetrates, through the free space 16 a and these passages 16, into the skimmer body where it is sucked by the pumping means through outlet 8.
- ballast 12 we can determine the weight of ballast 12 so that lifting the skimmer body and releasing the or 16 auxiliary passages occur while it still remains, inside the skimmer body, a small amount of water normally introduced through the opening 14 in floating bowl.
- the means used remain structurally simple and above all no manual intervention is necessary to pass from the functional configuration into normal situation at the functional configuration in abnormal situation.
- the different component parts are simple and inexpensive manufacturing (e.g. material molded plastic) and the price of a floating device as well arranged can remain relatively modest.

Description
- un support flottant présentant une embase de support, et
- un skimmer disposé dans ledit support flottant et retenu
sur ladite embase, ce skimmer comprenant :
- un corps de skimmer muni de moyens de butée propres à autoriser son déplacement vertical d'amplitude limitée au-dessus de l'embase,
- le corps de skimmer possédant un fond qui comporte un orifice principal central raccordable à un moyen de pompage et qui présente au moins un passage auxiliaire propre à être obturé par ladite embase quand le corps de skimmer repose sur celle-ci, et
- un bol flottant qui coiffe supérieurement le corps
de skimmer et qui est muni d'une ouverture axiale.
Un dispositif ainsi constitué remédie aux inconvénients
cités plus haut et évite le désamorçage de la
pompe :
- a) en fonctionnement normal du dispositif, le bol flottant est maintenu sous le niveau d'eau du bassin et recueille, par son ouverture axiale, un écoulement lamellaire d'eau qui tombe dans le corps de skimmer avant d'être aspiré par l'orifice principal sous l'action des moyens de pompage, tandis que le corps de skimmer partiellement rempli d'eau est "coulant" et est plaqué contre l'embase : ainsi le passage auxiliaire prévu dans le fond du corps de skimmer est obturé par l'embase;
- b) en fonctionnement anormal en raison d'un excès de flottabilité dû à un défaut de remplissage en eau, le corps de skimmer devient "flottant" et soulève le bol flottant au-dessus du niveau de l'eau du bassin en interrompant l'entrée d'eau dans le skimmer : le corps de skimmer se soulève alors au-dessus de l'embase en dégageant le passage auxiliaire de sorte que l'eau du bassin peut pénétrer dans le corps par ledit passage auxiliaire ainsi dégagé et est aspirée par le moyen de pompage à travers l'orifice central.
