Definitions
- the present invention relates to a pumping installation for pumping water on a site likely to present a significant tidal range, comprising a pumping device located on the ground, a floating head of water intake and a pipe system connecting the floating head of water intake to the pumping apparatus, the piping system comprising a ground pipe connected to the pumping apparatus and a flexible and flexible cuff which connects said floating head to the ground pipe and which allows a vertical movement of said floating head as a result of a variation in the water level, said floating head comprising a suction chamber with a water inlet opening and a sealed box forming a float, which is mounted above above the suction chamber.
- FR-A-1 283 671 already discloses a pumping installation of the above-mentioned type. It is an installation intended for the depletion of water in mines, quarries, excavations and others, in which the strainer, i.e. the intake head, is designed to be able to float in a vertical position in the liquid being pumped.
- the strainer i.e. the intake head
- no means are provided for adjusting the level or the depth at which the water inlet opening of the water intake head operates below the level of the water.
- the present invention aims to provide a water pumping installation meeting the above-mentioned requirements, without having the drawbacks of the second known installation.
- the water pumping installation according to the invention is characterized in that the floating head comprises means for adjusting its level of flotation by varying its weight in the water, so that, in operation , its water inlet opening remains at the desired depth below the water level regardless of the water level.
- said adjustment means may comprise a ballast compartment providing a fixed ballasting function, and at least one other sealed box capable of receiving through a filling orifice a mass of ballast having a weight which is chosen to determine the desired level of buoyancy of said floating head.
- the suction chamber has an elongated cross section and has an upper wall, a lower wall and two side walls, an open front end, which forms said water inlet opening, and an open rear end, which is connected to a rigid evacuation pipe which is itself connected, at its rear end, to the flexible cuff.
- a grille can be mounted at the open front end of the suction chamber.
- the waterproof case forming a float is fixed to the upper wall of the suction chamber, the ballast compartment is fixed to the lower wall of said chamber and another waterproof case is fixed to each of the two side walls of the chamber.
- the suction chamber is preferably shaped like a pyramid trunk with a rectangular base, to cause a gradual acceleration of the speed of flow of the water.
- the entrance to the suction chamber is 2 m high for immersion at a depth of 1.50 m
- the water suction speed is 0.50 m / s to the grid to avoid sucking the floating bodies and reaches 2.40 m / s in the evacuation pipe so that the settling of sand or mud is reduced.
- FIG. 1 shows a floating water intake head 1 secured to its rigid discharge pipe 2, itself connected to the earth pipe 3 by a flexible and flexible cuff 4.
- the head of the water intake has a suction chamber 5 (FIG. 2) of generally truncated pyramid shape, the side facing the water is provided with grids 6 and the opposite side extended by a rigid discharge pipe. 2.
- the suction chamber 5 is surmounted by a waterproof box shaped as a float 7, its lower part supports a ballast compartment 8 and its lateral faces each carry a waterproof box 9 (FIG. 3) intended to be more or less ballasted according to the buoyancy level sought for the head; these boxes 9 have for this purpose a filling orifice 10 at their top ( Figure 4).
- the water intake head is guyed by a tube 13 rigidly connecting its upper end to the rear end of its discharge pipe 2.
