Description

Method and apparatus for converting potential energy into kinetic energy for power generation

[Description]

The invention relates to a method and a device for converting potential energy into kinetic energy for energy generation and / or energy storage. The potential energy is represented by a gravitational force consisting, for example, of goods, media and / or persons (traffic flows) and which is usefully mobilizable in one direction at large airports, in department stores or in other facilities.

[State of the art]

Basically, it is known, for. B. from DE 10 2005 047 559 A1, potential energy into other forms of energy such. B. to convert electrical or thermal energy by the potential energy is brought from a higher to a lower level and then transferred by a buoyant force back to the starting position. An economically practical application of this system can not be seen. From DE 26 18 046 A1 is known in an electro-hydraulic lifting device, stored potential energy when unloading goods beneficially returned to the system. In the described method and arrangement, a pressure resulting from the lowering of the load is used to generate electric power for charging an accumulator. With this arrangement, no energy that can be used outside the system is generated, but only the complete discharge of the accumulator is delayed. -

Furthermore, WO 02/103201 A1 describes a system for utilizing the gravitational pressure, in which a loaded truck is brought on a platform from a higher level to a lower level. The weight of the truck is generated via a mechanical system, hydraulic compression and generator electrical energy.

The disadvantage of this arrangement is that not all the weight is used to generate energy. A swiveling mechanical system and an additional counterforce to bring the unloaded platform back to the higher level are required.

OBJECT OF THE INVENTION

The object of the invention is to provide a method and a device for converting potential energy into kinetic energy for power generation and / or energy storage, are exploited in the existing or organized traffic streams for energy. Furthermore, the device should be as simple as possible and constructed with a low material usage in order to achieve high efficiency with a low consumption of own energy.

The object is achieved in relation to the method with the features of the first claim and for the device with the features of the second claim. Advantageous developments and refinements are the subject of the dependent claims. The method and apparatus for converting potential energy into kinetic energy utilizes traffic streams that are unidirectional or can be organized to produce and / or store energy. Such traffic flows can be goods, goods, people or media, such as. As water or flowable sand, which represent a weight and are moved by means of a device from a higher level to a lower level.

Thereby, preferably, a pressure is generated, which directly serves the production of heat or electricity.

The device has, similar to an elevator, a platform that is loaded at the higher level and unloaded at the lower level, with a Part of the energy generated is used to bring the platform after discharge back to the higher level.

The platform is coupled to power generation and / or energy storage, for example, with a pressure generating device that generates heat or electricity by means of hydraulic or other types of machinery.

For an optimal ratio between the applied weight and the necessary restoring force, a weight of approximately 25,000 kg to 30,000 kg is necessary, provided the design according to the invention is used. That's about 300 adults. To be able to transport such a large number of people, it is expedient to equip the platform with several floors, for example, 5 floors a 60 people. In order to limit the height of the device, it is also advantageous to transport the persons sitting.

The device is based on a platform of lightweight construction starting from a triangular basic shape and made of known materials which are used, for example, in aircraft or rocket construction and which are stable enough to have a mass of 30,000 kg to be able to carry. As a particularly lightweight material which can be loaded with high pressure, the fabric airgel is suitable for many parts of the device. In the case of a multi-stage design of the platform, it must be taken into account that the stability of the supports must be proportional to the weight to be loaded in the individual floors.

Optimal is an embodiment as a pressure-generating device, which serves for the compression of a gas and / or for flow acceleration of a liquid or a gas. Thus, both a suspension is ensured, as well as the fall rate damped, a portion of the pressure is used as a return force and the pressure is used by the use of known machines for the generation and storage of electricity, heat or other forms of energy.

As optimal means of transport, a support frame is proposed for the device, which consists of at least one platform which is fastened to a central column. The platform is advantageously formed of three support arms, the Star-shaped, starting from the central column, are aligned at a distance of 120 °. Thus, the basic shape of the support frame in plan view forms an isosceles triangle.

The outer ends of the support arms are guided over rails friction in three columns, which form an outer frame and over which the access to the platform is ensured.

Via the central column, pressure is applied to a medium (gas or liquid) with the loaded platform for generating energy, and a hydraulic suspension pushes the empty framework back from below into its original position.

For energy generation known mechanisms are used. A weight force is moved from a higher level to a lower level, so that profitable electric power or heat can be generated.

In addition, this arrangement can be advantageously installed on dams. In addition to the use of water pressure to drive turbines excess Tai flowing into the tank at the upper level of the dam is filled in a container and the full water tank moves, similar to the traffic flows in the form of Goods or persons, in a vertically arranged in front of the dam wall or tube by its gravitational force down.

By the weight of the container, a pressure-generating device is actuated. At the lower end of the container is emptied and the empty container brought by a relative to the weight of the full container low counter-force for refilling again to the higher level. In addition to the use of pressure for energy, it is also conceivable to arrange linear motors between the container and the holding frame, via which electrical energy is generated directly or additionally.

Another useful arrangement results, for example, in the handling of containers or other heavy goods from ships to the road, on rails or vice versa. On the basis of the inventive idea and the basic structure of the device, numerous other application examples can be derived in which potential energy can be converted into usable kinetic energy by utilizing weight forces.

[Examples]

With reference to drawings, the structure and operation of the invention will be explained in more detail.

Show it:

1 is a perspective schematic representation of the device in execution with five floors for the transport of persons,

2 is a plan view of a platform according to Fig. 1,

Fig. 3 is a schematic representation of the device for using the weight of water containers.

Fig. 4 is a schematic representation of the device for using the weight during cargo handling.

For the transport of persons a device with a platform 1 is shown in Fig. 1, which is equipped with five floors.

The platform 1 is fixed to a central pillar 2, wherein each plane of the platform 1 consists of three horizontally oriented support arms 3, forming an isosceles triangle 4, aligned in a star shape from the central pillar 2. Each level of the platform 1 is constructed in the same way.

The outer ends of the support arms 3 are supported by supporting columns 5 vertically against each other (shown in Fig. 2) and thus form together with connection support rings 6 in the individual planes of a stable construction.

The support columns 5, which are also rail-shaped, slide friction in outer support columns 7, which may be part of a building at the same time. Between the outer support columns 7 and the levels accesses 8 (shown in Fig. 2) are arranged. To reduce the height of the platform 1, it is expedient to transport the persons sitting.

Starting from a normal storey height in buildings, two levels in the platform 1 can thus be loaded with persons. Furthermore, it is expedient in this context that the persons take place on roller seats and so drive on rails or rollers along the support arms 3 in the platform 1.

For the safety of the persons to be transported, the support frame 3, 4, 5, 6 of the platform 1, for example, covered with Plexiglas.

When the platform 1 moves under load from a plane A to a plane B, energy is generated by pressure of the central column 2 on a pressure accumulator and / or pressure transducer (not shown). For the further processing of the pressure generated by the central column 2, numerous methods and devices are known in the art. But it is also possible to equip the slide rails between the vertical support columns 5 and the outer support columns 7 with linear generators and thus to generate electrical energy directly.

By constructing the supporting structure 3, 4, 5, 6 in lightweight construction, made of known materials, which are used for example in aircraft or rocket construction and are stable enough to carry a mass of 30 000 kg, the need for own energy continues reduced.

Furthermore, the platform 1 is equipped both in the plane A, as well as in the plane B with a lock that is released in the plane A only when all persons have boarded or the platform 1 is loaded to the maximum. In level B, the platform 1 is also locked and only released when all persons have left or all goods are unloaded.

But it is also possible to solve the lock in connection with the closing of the access 8.

The weight of the persons creates a pressure-generating load (work) in the plane A. In level B, a reversal of the process takes place and the platform 1 moves back into the plane A. In level A, for example, as on an air terminal, always new people or come from the level B on a staircase or low energy on a paternoster back into the plane A.

In Fig. 2 is a plan view of a platform 1 of the power generating device is shown.

Starting from a carrier 4 in the form of an isosceles triangle, which forms the main column and / or is connected to the pressure-generating central column 2, star-shaped three support arms 3 go out. In the arrangement of a platform 1, which extends over five floors of buildings, 30 carrier arms 3 are necessary for a sedentary transport of persons. With 10 people on a support arm 3 so 300 people can be transported.

At their outer ends, the support arms 3 are fastened to vertical supporting columns 5 via anchors 9, as well as to the triangular support 4 of the central column 2. The vertical support columns 5 are connected to each other with a connection support ring 6.

The support columns 5 slide with low friction in outer support columns 7, which are part of a building and via which the accesses 8 to the platform 1 take place.

The embodiment shown in Fig. 3 shows in a schematic drawing as the invention can be used profitably on dams 10.

On the dry side 11 of the dam 10, a pipe or a frame 12 is arranged vertically by a large water tank 13 is arranged to fall down. The water tank 13 is in its upper position via an overflow pipe 14 and a controllable valve (not shown) filled with water from the reservoir. In the lower position, the water tank 13 is emptied by opening suitably located flaps. When shutting down the water tank 13 pressure is exerted on a piston 16 which is in communication with a non-running pressure-converting device 17.

When the water container 13 is arranged in a tube 12 which is sealed downwardly by the piston 16, the pressure can also be transmitted to the piston 16 by the air compressed in the tube 12 by the water container 13.

The capacity of the container 13 should be depending on the height of the dam 10 100,000 to 200,000 liters. In the pressure-converting device 17, the pressure-exerting weight of the water is converted into heat, mechanical or electrical energy. It is also possible to arrange a plurality of these pressure-generating devices 12, 13, 16, 17 on a dam 10.

One possibility of using the weight force when loading goods, in particular large containers 18, is shown in FIG. 4.

When handling containers 18, for example in a port, they are unloaded by a crane 19 and distributed according to their destination (a). During unloading, the goods 18 are in the meantime deposited on a platform 1 (b) before being sent to their destination (c). When lowering the load, for example for a logistically necessary stop, the weight of the full container 18 usefully generates energy by means of a modified device 16, 17 of the inventive solution. On a piston 16, which is in communication with an unspecified pressure-converting device 17, pressure is applied.
