Description

Device for energy production

The invention relates to a device for power generation, in particular a fully automatic, mobile device for the production of electrical energy by sunlight. The facility enables the uninterrupted supply of electric energy in impassable, undeveloped areas of the earth. It can be used for exploration, disaster relief, humanitarian and military purposes.

The only prerequisite for their use is the presence of sufficiently strong and sufficiently long-lasting solar radiation.

State of the art

Are known mobile devices for cleaning water for various applications, such as mining, agriculture, but also humanitarian purposes, such. For use in refugee camps (Ecosphere Technologies, 3515 S.E. Lionel Terrace, Stuart, FL, 34997, www.ecospheretech.com). The equipment is mounted in truck semi-trailers, comparatively large, heavy and bulky. To supply energy, solar cells are also provided, which are pushed out of the semitrailers in a moving-box-like manner with the help of push joints. At least the installation requires specialized personnel and special transport facilities. The push joints of solar cell panels make it difficult to use in harsh environments (desert, mountains ...) and are rigid after unfolding, so not following the course of the sun.

An "energy package for solar vehicle" is described in DE4003513. These foldable panels, in a similar form as known from a carton, mounted on a small car. The type of attachment, the type of unfolding and folding, the nature of the orientation to the sun is not described, but should probably be made manually. Likewise, it is not described how, after the folding, a "... remaining modulus surface of the sun remains facing".

A hand-held, hand-operated, small "solar charger" is described in Utility Model DE202004010896U1. Two hinged bodies, a lid body and a base body, carry on their inside solar cells, with the help of the charging of a battery to be made.

An electric dry shaver is described in DE3641978. This has solar cells, which are released by manually folding down an "energy cover". to Increasing the energy yield by increasing the "solar cell surface" is proposed attaching another plate-shaped "energy plates".

Because of their dimensions, the three solutions listed are exclusively intended to be oriented manually in the direction of the sun. Likewise, the unfolding of the sheet-like structures, which are to generate electrical energy from light irradiation, manually, so there is neither a drive available, nor solutions are delivered that make the deployment of the sheet-like structure inevitably.

A mobile generator device is described in WO 2013/091906. In a housing are solar cell modules that can take a transport position and a working position.

The enclosure protects the solar cell modules in the transport position by being located completely in the transport position within the same. The device is modular in that individual generator devices stack with industrial trucks and handle and cascade over a detachable housing connection.

Installation and uninstallation must be done manually. Manual intervention is required to move the solar cell modules from the transport to the working position or to change the working position.

Solutions based on standardized transport containers are known. Thus, a solution is described, called Energy Container, are transported in the solar cell panels and manually placed on the job site on this (Johannes Hübner factory electrical machinery GmbH, Siemensstr.7, 35394 casting). The device is rigid, tracking along the course of the sun is not possible.

A container-based solution is also offered by Mobile Grid (Mobile Grid, 3700 Buffalo Speedway, Suit 940, Houston, TX, 77098, www.mobilegrid.com). Level solar panels are manually moved along a rotation axis from a folded position to a pivoted position and rigidly bolted to swather-like struts. Motorized drives and automated operation are not provided.

As is apparent from the prior art, no solution is known, the fully automatic and self-sufficient work, if necessary, can protect itself from adverse environmental conditions and against vandalism itself and automatically passes from a closed, robust transport state in a deployed working condition. In particular, no solution is known which represents a standardized transport device in the core and can still follow the sun's course automatically. The aim of the invention is to provide a device for generating energy by solar radiation using solar cells.

Summary of the invention

According to the invention the object is achieved with the device according to claim 1. Further preferred embodiments will become apparent from the subclaims or the following description.

The core of the device for generating energy is a housing, which is similar to a standardized transport device, which is commonly referred to as a container. Its appearance is a cuboid body, completely enclosed, equipped with standardized hangers for transport and extremely robust and durable.

In this form, the device is transported to generate energy. Standardized, globally available solutions for ship, rail, truck and helicopter transport are available and can be used without restrictions.

At the place of use, surfaces which are equipped with solar cells automatically develop out of this cuboid body and are oriented at least approximately orthogonally to the sun. At night, in case of storm, storm or even threatening vandalism, the energy recovery system automatically encapsulates back to a cuboid body.

The equipment can be brought to the job site quickly, cost-effectively and easily using standardized, worldwide available loading and transport technology. There are no further requirements at the place of use besides an at least halfway level surface. The device must be simple and robust. All technically sophisticated components are neither visible nor accessible from the outside.

The device has two states of appearance, a transport and a working state.

In the transport state, the device forms a completely closed, cuboid body, which is robust enough to withstand even rough handling on ships, in harbors, in railroad or truck transport. Preferably, during transport, the external appearance is indistinguishable from that of a standard transporting device, just as mass, manageability and dimensions may correspond to exactly one standard transporting device.

At the place of use, the device can automatically move into the working state, such that, if the weather is suitable, ie solar radiation, from the cuboid Transport body solar cell surfaces grown, which are tracked automatically and at least approximately orthogonal to sunlight and fill energy storage. In periods without solar radiation, ie at night, in storm and rain, the device can automatically turn back into the cuboid transport state. This should protect the expensive and comparatively sensitive solar cells. Due to the energy storage, however, an uninterrupted release of energy can also take place in the periods in which an energy accumulation by means of the solar cells is impossible.

The housing of the power plant is divided into two parts. A frame-shaped lower part as a steel or aluminum frame construction comparatively small thickness forms the foundation of the power plant. On this foundation, electrically rotatable about a vertical axis, a box-shaped operating space is arranged, which is rigidly connected in the transport state with the frame-shaped lower part by electrically actuated locking elements.

In the box-shaped operating room various electrical components for converting the supplied from the solar cells, low-voltage DC voltage in the usual AC mains voltage are arranged. The box-shaped operating room is, as known from a container, closed with two massive doors. It also houses the control and regulation technology for fully automatic operation. The control technology is remotely controllable and remotely controllable, d. H. On site, no specialists are required to operate the power generation plant.

In the frame-shaped lower part, however, energy storage in the form of batteries are available. These are relatively heavy and cause the center of gravity of the power plant is low.

By means of vandal-proof mounted environmental sensors, the weather conditions at the place of use are determined and from this the behavior of the power generation plant is derived. In particular, the strength of the solar radiation, the wind speed, the dust concentration of the air and the humidity are determined. By means of the globally available GPS information, the position of the place of use and the orientation of the energy production plant can be determined and from this the direction of the solar radiation can be calculated and the energy production plant can be aligned therewith. If the parameters determined make it possible to conclude weather conditions that might cause damage to the device for generating energy, these are automatically encapsulated in a cuboid shape Body. It is able to withstand even the most adverse environmental and weather conditions while effectively protecting the valuable components of the energy production facility.

Two hinges are arranged symmetrically along the side surfaces of the cuboid body at its top. Side surface means that vertical surface of the cuboid body with the largest extent.

With the two hinges two flat, rotatable panels are connected to the cuboid body and relative to the movable about each 270 degrees. The panels carry one-sided solar cells and are designed as a frame construction such that the solar cells are sunk in the frame and are protected on its back by an additional planking. In the transport state, the panels are folded and parallel on top of the cuboid body over each other, the solar cells pointing down and are neither accessible nor visible from the outside. From the inside of the box-shaped space, the panels with electrically operated locking elements can be rigidly connected to the cuboid body.

About two linkages, designed as a four-joint coupling gear, the two panels are moved independently. The linkages are dimensioned so that they lie in the transport position of the power generation plant within the cuboid body and are encapsulated by this. For this purpose, a gap-like opening on at least one end face of the cuboid body is present, in which the rods dip and completely disappear in the transport position in this gap-like opening.

The poles have only swivel joints to ensure ruggedness and rigidity. In order to enable the comparatively large pivoting range of the panels of 270 degrees with good transmission behavior, the use of two parallel-coupled coupling gears is proposed per panel, which are arranged in parallel so that they do not pass through their dead spots simultaneously.

The movement of the two linkages via a respective drive shaft, which is arranged on the inside of the side surfaces of the cuboid body. This drive shaft ends in the gap-like opening of the cuboid body and is firmly connected to the linkage.

In the box-shaped operating space of the cuboid body at least three electric motor drives are present. These drives are designed so that they consume no energy in the static, ie not moving state. Two of these drives are intended to move the drive shafts for the two linkages. A third drive is responsible for the rotation of the box-shaped operating space relative to the frame-shaped lower part. All drives are equipped with a measuring system, ie the information provided by the measuring system clearly indicates the position of the panels and the relative rotation of the box-shaped operating room to the frame-shaped base. The drives are constructed and accessible in the box-shaped operating room so that in the event of an accident the movement around the azimuth joint and around the folding joints is possible manually by means of a crank.

Fixed on the top of the cuboid body is another, rigid panel with solar cells. This is in the transport state, i. the appearance of the device for generating energy as a cuboid body, covered and protected by the two rotatable panels. In the working state, with the sun in the zenith, the rigid and the two rotatable panels form an area which is at least three times the base of the cuboid body.
