DESCRIPTION:
BRIEF SUMMARY
This invention relates to an installation for generating utilizable energy from potential energy of slowly driving motor vehicles of the street traffic, wherein the machinery comprises at least one rigid swivel plate to be overtravelled by the motor vehicles and beared on a bearing block, the plate being lowerable under the weight of a motor vehicle, wherein a fluid being able to flow is urged out of flexible containers and directed into a pressure equalizing container being connected with a turbine or a hydraulic motor.
Such an installation for generating utilizable energy from potential energy of motor vehicles of street traffic is already known from the U.S. Pat. No. 4,339,920. According to this patent a plurality of flexible containers, which are filled with an incompressible fluid, are squeezed together, and subsequently the fluid is directed, may be after passing a flexible and hence extendable container, to a hydraulic motor for generating utilizable energy. The containers being compressible by the weight of a motor vehicle are disposed in small chambers which are inserted within the traffic lane, whereby the covers of these cheers can be urged by the weight of a motor vehicle into a position underneath the surface of the traffic lane. Thereby the tire of the motor vehicle is hit very hard like in case of driving through potholes.
Furthermore, an installation for generating utilizable energy from potential energy of motor vehicles is known from DE-OS 35 42 031. According to this specification, flexible containers filled with water are compressed by means of rigid swivel plates and the urged out water is fed for generating energy into a turbine.
It has shown to be a disadvantage of this installation, that there have to be taken special measures for driving back the urged out water into the flexible containers and thereby to move back the swivel plates into their original position. Furthermore, it has shown to be disadvantageous to urge an incompressible fluid out of the flexible containers, because in this case the energy cannot be accumulated without taking additional measures in form of a fluid under pressure and hence a turbine cannot be driven in an optional moment.
In order to render possible to accumulate energy in form of a fluid under pressure and furthermore to utilize the force of gravity of the water flowing out of the turbine, additionally for generating energy, it was further proposed (WO 90/08259) that the fluid being urged out of the flexible containers into the water-bearing pressure equalizing container is air which presses water through the turbine and through the hydraulic motor, respectively, and a storage container for water is positioned subsequently behind the turbine of the hydraulic motor, respectively, and the storage container is pivotably supported on the swivel plate on both sides of the bearing block, whereby the storage container assists in lowering the swivel plate and hence assists in driving out the air, wherein filling the storage containers is controlled by motor vehicleactuated signal transmitters which open and close valves, in such a way that the suitable storage container is exactly filled in the right moment so that it actually assists in lowering the plate caused by the motor vehicle.
An object of the invention is to further develop an installation of the present kind in such a way that the efficiency of the installation is further increased, even if the swivel mechanism has a small construction height with only a small swivel stroke of the swivel plate.
In meeting this object the invention is an installation for generating utilizable energy from potential energy of slowly driving motor vehicles of the street traffic, comprising a rigid first swivel plate being built in a traffic lane and being centrally pivoted, said first swivel plate being supported on flexible first air containers to be compressed by the swiveling of the first swivel plate and being coupled by means of a power transmission with a rigid second swivel plate being located laterally of the fi
