Description

Technical area

The present invention relates to an energy-autonomous mobile radio platform.

State of the art

In the field of mobile radio technology, it is known to use base stations as stationary devices for the transmission of radio signals, which base stations usually contain an antenna carrier for holding a large number of transmitting antennas. A common embodiment of such an antenna support is a free-standing tubular steel construction. In cases in which the antenna supports are to be set up away from facilities of an electrical power network, the transmitting antennas must be supplied with electrical energy from auxiliary devices such as a battery pack.

The technical field of setting up and supplying transmission antennas in mobile radio technology with electrical energy at locations far from facilities of an electrical power network therefore still offers room for improvement.

Object of the invention

The present invention is therefore based in particular on the object of simply and reliably positioning a transmitting antenna or a plurality of transmitting antennas for mobile radio remote from facilities of an electrical power network on an uneven surface and operating them over a longer period of time.

Disclosure of the invention

According to the invention, the object is achieved by an energy-autonomous mobile radio platform with the features of claim 1. Further, particularly advantageous refinements of the invention are disclosed in the dependent subclaims.

It should be noted that the individual features used in this description are listed, can also be combined with one another in any technically meaningful manner and represent further embodiments of the invention.

The energy-autonomous mobile radio platform according to the invention includes a mechanical basic structure, a multiplicity of reversibly fillable hollow bodies, at least one regenerative energy generating device, at least one converter unit, at least one mobile radio mast and electrical supply lines.

The mechanical base structure has compensating elements for horizontal mounting on a base, the base structure forming a plurality of holding frames. The hollow bodies are intended to weigh down the mechanical basic structure. Each hollow body has at least one fastening element on an upper side and is held in one of the holding frames. The at least one regenerative energy generating device is held on at least one fastening element of at least one of the hollow bodies. The at least one converter unit is provided for converting electrical energy generated by at least one energy generating device. The at least one cell phone mast is provided to hold at least one transmitting antenna of the cell phone and is in turn held on at least one fastening element of at least one of the hollow bodies. The electrical connecting lines connect the at least one converter unit to the regenerative energy generation device and the at least one transmitting antenna.

In the context of the invention, the term “multiplicity” should in particular be understood to mean a number of at least two. In the context of the invention, the term “intended for this purpose” should be understood in particular to be specifically designed or arranged for this purpose.

With the proposed energy-autonomous mobile radio platform, a transmission antenna or several mobile radio transmission antennas can be easily and reliably positioned on an uneven surface far away from facilities of an electrical power network and operated for a longer period of time using the electrical energy generated by the at least one regenerative energy generating device. The length of the period is mainly determined by maintenance intervals.

The maximum power that can be generated by each of the at least one energy generating device is preferably between 1 kW and 10 kW.

The hollow bodies for weighting can preferably be made of plastic, for example. They can be reversibly filled with an inexpensive filler such as, but not limited to, water or sand through an at least one inlet opening preferably provided on the upper side. The hollow bodies can be equipped on their underside with at least one outlet opening which allows the hollow body to be emptied in an installed state.

In preferred embodiments of the mobile radio platform, each holding frame is formed by a multiplicity of steel profile elements fastened to one another. The holding frames are furthermore evenly spaced apart in two mutually independent spatial directions. In this way, the mechanical basic structure can provide the multiplicity of holding frames in a structurally particularly simple manner and in a manner that is particularly variable in terms of design.

The two mutually independent spatial directions can preferably be arranged perpendicular to one another, as a result of which a structurally simple solution for the mechanical basic structure with a high utilization of space can be achieved.

Furthermore, each of the hollow bodies is preferably equipped with at least one molded-on form-fit element which forms a form-fit connection with one of the holding frames for holding purposes. As a result, a particularly reliable and resilient holding of each of the hollow bodies in one of the holding frames can be achieved in a structurally and manufacturing-simple manner.

In preferred embodiments of the mobile radio platform, at least one of the at least one regenerative energy generating device is designed as a wind turbine device. Such a mobile radio platform can be used advantageously in cases in which a transmitting antenna or several transmitting antennas of the cellular network are to be positioned at a location far away from facilities of an electrical power network and to be operated for a longer period of time using the electrical energy generated by the at least one regenerative energy generating device which is in a free, wind-unprotected position.

The wind turbine device is preferred as a vertical rotor ("Vertical Axis Wind Turbine", VAWT) with a vertically arranged axis of rotation. In this way, a mobile radio platform can be provided with an electrical supply by wind energy, which requires a particularly small base area for mounting. Furthermore, a device for tracking the wind direction can be dispensed with.

In preferred embodiments of the mobile radio platform, the wind turbine device is designed as a Savonius rotor with helical rotor blades. As a result, a mobile radio platform can be provided with an electrical supply by wind energy, which has a particularly high degree of efficiency within a comparatively large wind speed range and in particular at a relatively low wind speed.

In preferred embodiments of the mobile radio platform, at least one of the at least one regenerative energy generating device is designed as a photovoltaic system with at least one photovoltaic module. Such a mobile radio platform can be used advantageously in cases in which a transmitting antenna or several transmitting antennas of the cellular network are to be positioned at a location far away from facilities of an electrical power network and to be operated for a longer period of time using the electrical energy generated by the at least one regenerative energy generating device which is located in a comparatively sunny zone and in particular where there is no risk of prolonged shading.

The mobile radio platform is preferably equipped with a large number of rechargeable energy storage elements for the intermediate storage of electrical energy generated by means of at least one of the regenerative energy generation devices. In this case, the energy storage elements are connected in an electrically effective manner to the at least one converter unit. In this way, a higher temporal availability of the at least one transmitting antenna of the mobile radio can be made possible independently of an instantaneous energy generation.

The energy storage elements can be designed, for example, without being restricted thereto, as a rechargeable battery (secondary cells or battery pack), for example as a lead-acid battery or lithium-ion battery, or as a supercapacitor. The energy storage elements can be connected electrically in parallel and / or electrically in series in a manner known per se.

In preferred embodiments of the cellular radio platform, the at least one cellular radio mast is equipped with a wrapping device. The enveloping device contains at least one pliable sleeve which, in an installed state, is designed in the form of a straight elliptical cylinder and has a lower edge area and an upper edge area. The wrapping device furthermore has at least one upper holding device and at least one lower holding device, which each extend essentially in one plane and are each attached to the cell phone mast with a mast-side end of a plurality of fastening struts. In this case, ends of the fastening struts facing away from the mast are connected to at least one holding element of the respective holding device which extends in a circumferential direction of the respective plane at least along part of the circumference. A total of the extension of all mounting elements makes up a predominant part of the circumference. In the installed state, the at least one holding element of the upper holding device is operatively connected to the upper edge region of the flexible cover and the at least one holding element of the lower holding device is operatively connected to the lower edge region of the flexible cover.

In the context of the invention, a "pliable" shell is to be understood as meaning in particular a shell made of a flat material which, free-standing, can absorb an externally acting force in a direction transverse to the surface, which is only a small fraction, for example less than 1% from the outside force that can be maximally absorbed by the flat material in directions that lie within the surface.

In the context of the invention, a "straight elliptical cylinder shape" is to be understood as meaning in particular the shape of a cylinder jacket, the central axis of which is arranged perpendicular to its base area, the base area being elliptical and, in particular, being able to be circular.

In this context, the term “operatively connected” is to be understood in particular to mean that operatively connected objects are connected to one another in such a way that a force can be transmitted between the objects. The transmission can take place either through direct contact or indirectly, through at least one intermediate element.

With the proposed enveloping device, a cladding of the cell phone mast is provided, by means of which the expenditure for creating molding tools that can be easily installed and designed and dimensioned in a flexible manner can be avoided. The flexible cover of the wrapping device can protect the cell phone mast and possibly attached transmitting antennas from environmental and weather influences. In suitable embodiments, the wrapping device can adapt the mobile radio mast to its surroundings at its location away from facilities of a power network and thereby make it less conspicuous.

Such mobile radio masts with a wrapping device are described in detail in the Luxembourg patent application LU 101348. The patent application LU 101348 is hereby to be included in its entirety by inclusion by reference, with effect for those patent jurisdictions that allow inclusion by reference.

Description of the exemplary embodiments

Fig. 1 shows a schematic representation of a possible embodiment of the energy-autonomous mobile radio platform 10 according to the invention in an assembled state in a perspective, elevated view.

The energy-autonomous mobile radio platform 10 includes a mechanical basic structure 12 with an essentially rectangular base area, two different regenerative energy generation devices 26, 32 and a mobile radio mast 52 which is equipped with a wrapping device 60.

One 26 of the regenerative energy generating devices 26, 32 is designed as a wind turbine device, which in this special embodiment is designed as a vertical rotor with a vertically arranged axis of rotation 28 and is fastened to an upper side of the mechanical basic structure 12. The vertical rotor can be, for example, a modified Savonius rotor with helical rotor blades. A maximum electrical power that can be generated by the vertical rotor can be, for example, 3 kW.

The other 32 of the regenerative energy generating devices 26, 32 is designed as a photovoltaic system with a large number of a total of 14 photovoltaic modules 34, which are attached to the top of the mechanical basic structure 12 in four rows arranged parallel to one another. A maximum electrical power that can be generated by the photovoltaic system can be, for example, 1.5 kW _peak .

Fig. 2 FIG. 11 shows a schematic representation of the mechanical basic structure 12 of the energy-autonomous mobile radio platform 10 according to FIG Fig. 1 in a perspective, elevated view. The mechanical basic structure 12 contains a multiplicity of 16 compensating elements 14 for horizontal mounting on a substrate 96, which can have unevenness in the size of a compensating area of the compensating elements 14. The compensating elements 14 can be designed, for example, as a threaded spindle. The mechanical basic structure 12 includes a plurality of steel profile elements 16, 18 fastened to one another, which, among other things, form a plurality of four holding frames 20, of which one holding frame 20 is arranged in a corner area of the essentially rectangular, mechanical basic structure 12. In the Fig. 2 one of the holding frames 20 is marked with dashed lines. In this way, the holding frames 20 are in two of each other independent spatial directions (X-direction, Y-direction), which run parallel to edges of the essentially rectangular base area of the mechanical base structure 12, arranged at a uniform distance. Due to the rectangular shape of the base area, the two spatial directions that are independent of one another are aligned in particular perpendicular to one another. For the mechanical reinforcement of the corner areas, the mechanical basic structure 12 can be equipped with reinforcement plates 24, which essentially have an L-shape and are aligned parallel to the edges of the respective corner area.

The rectangular shape of the mechanical basic structure 12 forms a usable area with a size of approximately 6 m × 6 m. In alternative exemplary embodiments, the mechanical basic structure 12 can be connected to identically constructed further mechanical basic structures in order to provide a modular constructed basic structure with a larger usable area.

The energy-autonomous mobile radio platform 10 contains a large number of, in this special exemplary embodiment, a total of 24 plastic hollow bodies 36 for weighting the mechanical basic structure 12 Figures 3 to 5 show one of the identically shaped plastic hollow bodies 36 in a perspective, elevated view, in a front view and in a top view.

The plastic hollow body 36 essentially has a cuboid shape with an integrally molded, horizontal recess 38 extending along a circumference. The recess 38 gives the cuboid shape of the plastic hollow body 36 increased mechanical stability. A recess 40 with a constant cross-sectional area is formed on an underside of the cuboid shape, an extension of the recess 40 running parallel to a narrow side of the larger rectangle of the cuboid shape. The recess 40 forms a form-fit element 42 in an upper region, which in an installed state of the plastic hollow body 36 is provided with a steel profile element 18 serving as a corresponding form-fit element ( Fig. 2 ) of the holding frame 20 for holding the plastic hollow body 36 forms a form-fit connection.

The plastic hollow bodies 36 can be filled reversibly, for example with water or fine sand, and are equipped with two filling openings 44, 46 on the upper side of the cuboid shape for the purpose of filling ( Fig. 3 ). The plastic hollow body 36 can be emptied via a resealable opening 48 at a corner on the underside of the cuboid shape in order to reduce the weight of the mechanical basic structure 12 when a change in the location of the mobile radio platform 10 is to be carried out.

The plastic hollow bodies 36 each have a plurality of eight fastening elements 50 on the upper side of the cuboid shape, each of the fastening elements 50 being designed as a threaded hole. Like in the Fig. 1 As shown, the regenerative energy generating devices 26, 32 are held on the fastening elements 50 of the hollow plastic body 36. The vertical rotor is held by means of a stand 30 and eight fastening screws on all six plastic hollow bodies 36, which are arranged in the holding frame 20 in a right front corner area of the mechanical basic structure 12, whereby sufficient fastening can be ensured even during operation of the vertical rotor.

The mobile radio platform 10 also contains a converter unit (not shown) for converting the electrical voltage generated by the regenerative energy generating devices 26, 32. Electrical connection lines (not shown) connect the converter unit to the regenerative energy generating devices 26, 32. The converter unit contains a rectifier for rectifying the AC voltage generated by the vertical rotor and a downstream DC / DC converter that converts the rectified AC voltage to a voltage level with which a large number of rechargeable energy storage elements (not shown) can be charged, which are formed by lithium-ion batteries and, for example, in a central area 22 ( Fig. 2 ) the mechanical basic structure 12 can be arranged and supported. For this purpose, the energy storage elements are connected to the converter unit in an electrically effective manner.

A separate DC / DC converter is provided to convert the direct voltage generated by the photovoltaic system to the voltage level suitable for charging the energy storage elements. The rechargeable energy storage elements serve as intermediate storage for excess electrical energy generated by the regenerative energy generation devices 26, 32. The stored electrical energy can be drawn from the energy storage elements at times when the regenerative energy generating devices 26, 32 cannot generate sufficient energy and can be provided by the latter by means of the electrical connection line to the converter unit.

The cellular tower 52 of the cellular radio platform 10 is used to hold a large number of six transmitting antennas 54 of the cellular radio ( Fig. 6 ). The cell phone mast 52 has in a lower part a tubular steel frame 56 with four standpipes 58 set up vertically at the corners of an imaginary square and is in turn held with the ends of the standpipes 58 on four fastening elements 50 of four different plastic hollow bodies 36, which are held in the holding frame 20 in a left rear corner area of the mechanical basic structure 12 are arranged ( Fig. 1 ). Electrical connection lines (not shown) connect the converter unit to the transmission antennas 54 of the mobile radio.

The enveloping device 60 of the cellular tower 52 includes two flexible sleeves 62, 78, which are in the Fig. 6 Installed state shown in each case in the form of a straight elliptical cylinder with an identical, circular cross-sectional area and which are arranged one above the other, adjoining one another and in a concentric manner. The two flexible sleeves 62, 78 each have an upper edge area 64, 80 and a lower edge area 66, 82 with a circumferential piping (not shown) and are each provided with an upper mounting device 70, 86 and a lower mounting device 72, 88 of the wrapping device 60 attached to the cell tower 52.

Each of the two pliable covers 62, 78 is equipped with a zipper 68, 84 which is aligned along the full length of a surface line of the straight elliptical cylinder and is intended to completely and reversibly divide the respective pliable cover 62, 78 along the surface line. The zipper 68, 84 is provided in particular to be opened prior to assembly in order to simplify the installation of the respective flexible cover 62, 78.

The pliable cover 78 arranged at the bottom has two through openings 94 ₁ , 94 ₂ , which are spaced apart from one another in the vertical direction and are arranged at the same position in the circumferential direction. Through the through openings 94 ₁ , 94 ₂ , fluid-technical connections are established between an interior space enclosed by the flexible casing 78 and the external environment. By introducing a directed forced flow of air by means of a fan into the interior, the blown air can be _{diverted through the passage openings 94 1} , 94 _{2 in} order to Cooling of the transmitting antennas 54 to achieve a desired temperature profile along the tubular steel frame 56 of the cell phone tower 52.

The upper mounting devices 70, 86 and the lower mounting devices 72, 88 each extend essentially in a horizontal plane and are each attached to the cell phone mast 52 with a mast-side end of a plurality of four mounting struts 74, 90. Ends of the fastening struts 74, 90 facing away from the mast are connected to a holding element of the respective holding device which extends in a circumferential direction of the respective plane along a predominant part of the circumference. In the installed state, the mounting element of the respective upper mounting device 70, 86 is connected to the upper edge area 64, 80 of the respective flexible cover 62, 78 and the mounting element of the respective lower mounting device 72, 88 is connected to the lower edge area 66, 82 of the respective flexible cover 62, 78 functionally connected.

The wrapping device 60 includes an upper tensioning device 76 for tensioning the pliable cover 62 arranged at the top and a lower tensioning device 92 for tensioning the pliable cover 78 arranged at the bottom, each of which has a plurality of tensioning elements, for example as threaded screw elements and in a useful combination in the form of a Threaded screw, threaded rod, screw nut or through opening can be formed.

Each of the fastening struts 74 of the upper mounting device 70 of the pliable cover 62 arranged at the top has an end remote from the mast, which is connected to the mounting element, one of the clamping elements of the upper clamping device 76 between the mounting element and an end remote from the mast of one of the mounting struts 74 to establish this connection is arranged operatively connected, so that operative connections are set up at a plurality of positions in the circumferential direction between the mounting element and the upper edge region 64 of the flexible cover 62 arranged at the top, by means of which the flexible cover 62 arranged at the top can be tensioned.

Each of the fastening struts 90 of the lower holding device 88 of the pliable sheath 78 arranged at the bottom has an end remote from the mast, which is connected to the holding element, one of which is used to produce this connection Tensioning elements of the lower tensioning device 92 between the holding element and an end remote from the mast of one of the fastening struts 90 is arranged in operative connection, so that operative connections between the holding element and the lower edge region 82 of the pliable cover 78 arranged at the bottom are established at a plurality of positions in the circumferential direction, by means of which the pliable sheath 78 arranged at the bottom can be stretched.
