- the present invention refers, as its title indicates, to a pumping system that is operable by sea waves and that allows to obtain a water flow at a high pressure, which can be used to obtain mechanical or electrical energy or to desalinate seawater by means of reverse osmosis membranes.
- the pumping system that can be operated by sea waves, object of this invention, allows to obtain a water flow at a high pressure, having been designed to be positioned on land and very close to the sea.
- this pumping system comprises a fixed support structure, folding arms and auxiliary arms that start from said fixed structure in the direction of the sea, floats mounted on the front ends of the mentioned arms, structures folding mounted on the fixed structure, intermediate elements for the transmission of the movement of the folding arms to the corresponding folding structures, some pumping cylinders, rocker arms that transmit the movement of the folding structures to the pumping cylinders by means of connecting rods , means to ensure the rectilinear movement of the pistons corresponding to the pumping cylinders and some compensating devices for the variations in height of the folding structures due to the effect of the tide.
- Both the folding and auxiliary arms are fixed at one of its ends to the fixed structure by means of two axes of rotation, said arms being folded towards the upper area by the action of the waves on the float mounted on the free end thereof and towards the lower area due to the weight of the arms when the water-supported float allows it.
- the floats are mounted on the folding arms and the auxiliary arms by means of a structure fixed to those by means of the corresponding axes of rotation, ensuring the parallelism of said arms and the vertical displacement of the float due to the effect of the waves.
- the intermediate elements responsible for transmitting the movement of the folding arms to the folding structures are composed of articulated connecting rods on the middle area of the folding arms and on the front end of said folding structures.
- collapsible structures which can be one or several arranged in parallel, are mounted at their rear end and by the corresponding axes of rotation on the fixed structure, being positioned above it and protruding its front end with respect to said fixed structure in the direction Sea.
- the rockers and the corresponding folding structures are related by their middle areas by means of turning axes. These axes of rotation allow to vary the inclination of the rockers with respect to the folding structures during the operation of the pumping system to absorb the differences in level of the floats due to the effect of the tides.
- the cylinders are fixed at their lower end to the fixed structure and that the pistons thereof are fixed to a cross member integral to carriages arranged in parallel to said cylinders and mounted with the possibility of longitudinal displacement on guides defined for this purpose in the mobile structure.
- the connecting rods responsible for transmitting the movement of the folding structures to the pumping cylinders are fixed at their ends, by means of the corresponding axes of rotation, to the front end of the aforementioned rocker arms and to the crossbar mounted on the carriages and which supports the piston heads.
- the compensating devices for the variations in height of the folding structures due to the effect of the tide include telescopic arms that form a rocker support point, hydraulic cylinders to vary the inclination of the telescopic arms and the rocker arm support point. on them and a hydraulic circuit that acts on the telescopic arms and on the hydraulic cylinders mentioned adjusting their position based on the travel in the piston cylinders of the pumping cylinders.
- the telescopic arms which conform to the support point of the rocker arms, are fixed at one of their ends to the fixed structure by means of an axis of rotation and have at the opposite end a skate mounted with the possibility of longitudinal displacement on the part rear of the corresponding rocker.
- skates are mounted on the rear end of the telescopic arms and can be moved along the rear part of the rocker arms by the operation of the hydraulic cylinders mentioned, so that when approaching or moving the skates from the pivot point of the seesaws are able to vary their relative inclination with respect to the folding structures.
- the displacement of the skates and the variation in the length of the associated telescopic arms are automatically controlled by means of a hydraulic circuit provided with an oil tank, a hydraulic distribution box, career regulating pumps, pumps emergency and flow regulating pumps.
- the stroke regulating pumps are fixed to the fixed structure in areas slightly distanced from the extreme points of the maximum travel of the carriages, so that when the stroke of the pistons is offset to the lower zone or to the upper zone due to the change of relative position of the mobile structures by the effect of the tide, the cars act on the stroke regulating pumps arranged in the upper or lower zone, the hydraulic circuit acting on the telescopic arms or on the cylinders responsible for moving the skates on the rear section of the rocker arms, varying their relative inclination with respect to the mobile structures until the centering of the stroke of the pistons corresponding to the pumping cylinders is achieved.
- the emergency pumps mentioned above are fixed to the fixed structure, in areas close to the extreme points of the maximum travel of the cars, one of said emergency pumps being operated when the stroke of the pistons corresponding to the pumping cylinders has a excessive de-centering towards one of the ends, which can be produced, for example, by a wave of greater height.
- the operation of one of the emergency pumps causes an action on the telescopic arms and on the hydraulic cylinders responsible for the displacement of the skates to achieve a rapid modification of the tilt of the rocker, varying its reactive inclination with respect to the structure mobile, to get the centering of the stroke of the pistons.
- FIG. 1 shows a profile view of an embodiment example of the pumping system object of the invention in which one of the pumping groups can be observed, since in the case of having said system of several pumping groups, these would be arranged in parallel to the one represented and, therefore, hidden by it.
- FIG. 1 shows a profile view of an embodiment example of the pumping system object of the invention in which one of the pumping groups can be observed, since in the case of having said system of several pumping groups, these would be arranged in parallel to the one represented and, therefore, hidden by it.
- an intermediate part of the folding and auxiliary arms has been removed, due to their high length with respect to the rest of the system components.
- FIG. 2 shows a partial view, in profile, of the pumping system shown in the previous figure and in an intermediate pumping position.
