Description

Beschreibung description

[0001 ] Die vorliegende Erfindung betrifft einen Schacht- oder Zugangsdeckel. The present invention relates to a manhole or access cover.

[0002] Unter Schacht ist im vorliegenden Zusammenhang eine ins Freie führende, verschliessbare Öffnung zu einem Raum zu verstehen. Üblicherweise ist ein solcher Raum mindestens teilweise im Boden angeordnet. Zwingend ist dies aber nicht, der Raum muss auch nicht zwingend begehbar sein. Under shaft is to be understood in the present context a leading into the open, lockable opening to a room. Usually, such a space is at least partially disposed in the ground. But this is not mandatory, the room does not necessarily have to be accessible.

[0003] In erster Linie geht es um Brunnendeckel. Ein Brunnendeckel ist in der Regel der einzige sichtbar, aus dem Erdboden reichende Teil einer Brunnenstube. Brunnenstuben sind Quellfassungen zur Gewinnung von Trinkwasser. Der Brunnendeckel verschliesst nach oben/aussen eine in die Brunnenstube führende Öffnung, beispielsweise ein Schacht. Durch diesen ist die Brunnenstube zu Wartungs- und Kontrollzwecken zugänglich. Im Schacht oder in der Brunnenstube sind meistens entsprechende Mess-, Warn- und/oder Steuergeräte vorhanden, zur Überwachung verschiedenster Parameter und allenfalls zur Störungsmeldung. Da diese Geräte elektrischen Strom benötigen, muss entweder eine Stromzuleitung oder, wo dies nicht sinnvoll realisierbar ist, eine Batterie vorgesehen sein. First and foremost, it is about fountain lid. A well cover is usually the only visible, reaching out of the ground part of a well room. Wellstuben are spring sockets for the production of drinking water. The well cover closes up / outside an opening leading into the well room, for example a shaft. Through this the well room is accessible for maintenance and control purposes. In the shaft or in the well room usually appropriate measuring, warning and / or control devices are available for monitoring a variety of parameters and possibly for fault reporting. Since these devices require electrical power, either a power supply line or, where this is not feasible, a battery must be provided.

[0004] Allgemein ist man in jüngerer Zeit zum Aufladen der Batterie von isoliert stehenden Anlagen jeglicher Art dazu übergegangen, eine oder mehrere Solarzellen, beziehungsweise photovoltaische Zellen zu verwenden. Das entsprechende, paneelartige Solarmodul wird bisher gewöhnlich an einer neben der Anlage stehenden Stange oder an einem kleinen Mast angebracht. In general, one has recently moved to recharge the battery of isolated systems of any kind to use one or more solar cells, or photovoltaic cells. The corresponding, panel-like solar module is usually attached to a standing next to the plant rod or on a small mast.

[0005] Würde man dies auch im Fall einer Brunnenstube oder dergleichen tun, so wäre zwischen dem Solarmodul und dem Schacht eine elektrische Verbindungsleitung erforderlich. Es versteht sich von selbst, dass sowohl das Solarmodul als auch die elektrische Verbindungsleitung relativ ungeschützt sind. Beschädigungen durch äussere Einflüsse, sei es durch Witterung, Vandalismus oder auch durch Tiere, können nicht ausgeschlossen werden. Eine ähnliche Situation wie bei den Brunnenstuben ergibt sich auch bei Wasserreservoiren oder bei sonstigen, verschliess-baren Behältern und Tanks, die Stromverbraucher aufweisen. Would you do this in the case of a well room or the like, so an electrical connection line would be required between the solar module and the shaft. It goes without saying that both the solar module and the electrical connection line are relatively unprotected. Damage caused by external influences, be it due to weather, vandalism or even animals, can not be ruled out. A similar situation as in the wells also results in water reservoirs or other, closable containers and tanks that have electricity consumers.

[0006] Auf der Grundlage dieses Standes der Technik setzt sich die Erfindung die Aufgabe, einen Schacht- oder Zugangsdeckel zu schaffen, durch den eine sichere Stromversorgung von diesen zugeordneten Stromverbrauchern gewährleistet ist. On the basis of this prior art, the invention has the object to provide a manhole or access cover, through which a secure power supply is ensured by these associated power consumers.

[0007] Bei diesen Stromverbrauchern kann es sich um unter dem Schacht- oder Zugangsdeckel angeordnete Mess-, Warn-, Steuergeräte, Sensoren, Beleuchtungen und dergleichen handeln. Es sind aber uneingeschränkt jegliche, elektrischen Strom verbrauchende Geräte denkbar, mit oder ohne Zwischenschaltung von Batterien, beziehungsweise von Akkumulatoren. These power consumers may be arranged under the manhole or access cover measuring, warning, control devices, sensors, lighting and the like. However, there are unrestricted any, electrical power consuming devices conceivable, with or without the interposition of batteries, or accumulators.

[0008] Der erfindungsgemässe Schacht- oder Zugangsdeckel entspricht den kennzeichnenden Merkmalen des Patentanspruchs 1. Weitere vorteilhafte Ausbildungen des Erfindungsgedankens sind aus den abhängigen Patentansprüchen ersichtlich. The inventive shaft or access cover corresponds to the characterizing features of claim 1. Further advantageous embodiments of the inventive concept can be seen from the dependent claims.

[0009] Nachfolgend werden bevorzugte Ausführungsbeispiele der Erfindung anhand der Zeichnung näher beschrieben. Hereinafter, preferred embodiments of the invention will be described in more detail with reference to the drawing.

Fig. 1 zeigt ein erstes Ausführungsbeispiel eines Schacht- oder Zugangsdeckel im Schnitt; Fig. 1 shows a first embodiment of a manhole or access cover in section;

Fig. 2 zeigt ein zweites Ausführungsbeispiel, ebenfalls im Schnitt Fig. 2 shows a second embodiment, also in section

[0010] Dargestellt ist jeweils die zu verschliessende Öffnung, beziehungsweise das obere Ende eines Schachtes 1. Darauf ist der erfindungsgemässe Schacht- oder Zugangsdeckel 2 gesetzt. Der Schacht 1 kann beispielsweise kreisrund sein. Es ist aber auch jede andere Querschnittsgeometrie möglich. Shown in each case is the opening to be closed, or the upper end of a shaft 1. Then the inventive shaft or access cover 2 is set. The shaft 1 may be circular, for example. But it is also possible any other cross-sectional geometry.

[0011 ] Wie bei Schacht- oder Zugangsdeckeln 2 üblich, kann dieser bombiert sein, siehe Fig. 1. Bei Brunnenstuben muss der Schacht- oder Zugangsdeckel 2 belüftet sein, das heisst, bei sich mit Wasser füllender Brunnenstube muss die Luft nach aussen entweichen können. Hierzu ist zum Beispiel eine Doppelwandkonstruktion vorgesehen, mit einer nach unten gerichteten Ringöffnung 3. Um kleinere Tiere und grössere Insekten am Eindringen in den zwischen der Deckelaussenwand 4 und der Deckelinnenwand 5 gebildeten Zwischenraum 6 zu hindern, kann ein Gitter 7 vorhanden sein. Das Innere 8 des Schachtes 1 kann zusätzlich durch einen Filter 9 vor Verschmutzungen geschützt sein. Der Filter 9 ist an der Durchgangsöffnung zwischen dem besagten Inneren 8 und dem Zwischenraum 6 angeordnet. Im Weiteren kann der Schacht- oder Zugangsdeckel 2 ein Scharnier 10 und einen für Unbefugte nicht so leicht zu öffnenden Verschluss 1 1 aufweisen. Der Schacht- oder Zugangsdeckel 2 kann im Übrigen aus einem beliebigen, stabilen Werkstoff bestehen, angefangen bei Kunststoff. Sinnvoll ist aber ein Stahldeckel. As usual with manhole or access covers 2, this can be cambered, see Fig. 1. In Wellstuben the manhole or access cover 2 must be ventilated, that is, when filled with water well room, the air must be able to escape to the outside , For this purpose, for example, a double-wall construction is provided, with a downwardly directed annular opening 3. In order to prevent smaller animals and larger insects from entering the intermediate space 6 formed between the outer lid wall 4 and the inner lid wall 5, a grid 7 may be present. The interior 8 of the shaft 1 can additionally be protected by a filter 9 against contamination. The filter 9 is arranged at the passage opening between the said interior 8 and the gap 6. Furthermore, the shaft or access cover 2 may have a hinge 10 and a closure 1 1 which is not easily opened by unauthorized persons. Incidentally, the shaft or access cover 2 can be made of any stable material, starting with plastic. But it makes sense to use a steel lid.

[0012] Erfindungsgemäss weist der Schacht- oder Zugangsdeckel 2 mindestens eine photovoltaische Zelle auf, vorzugsweise mindestens ein Solarmodul 12, zur Umwandlung von Strahlungsenergie, beziehungsweise Sonnenlicht in elektrische Energie. According to the invention, the shaft or access cover 2 at least one photovoltaic cell, preferably at least one solar module 12, for the conversion of radiant energy, or sunlight into electrical energy.

[0013] In den beiden dargestellten Ausführungsbeispielen ist das Solarmodul 12 jeweils unter einer lichtdurchlässigen Abdeckung 13 angeordnet. Diese Abdeckung 13 sollte einigermassen stabil sein. Beispielsweise könnte sie aus einem gepanzerten Sicherheitsglas bestehen. Es käme eventuell auch eine geeignete Kunststoffabdeckung in Frage, soweit eine In the two illustrated embodiments, the solar module 12 is disposed under a translucent cover 13 respectively. This cover 13 should be reasonably stable. For example, it could consist of an armored safety glass. It might also be a suitable plastic cover in question, as far as a

Claims

adequate breakage is given. In contrast to the embodiment of FIG. 1, the cover 13 in the second example of FIG. 2 is flat, so not cambered, or arched outwards. It is also possible a combination of both solutions, for example, a centrally domed cover 13 with a flat edge. Explicit but not excluded are other shapes. However, it is advantageous if the cover 13 is installed in the lid surface such that there is no sufficient approach to break it out of its attachment. This applies to both drawn proposals. Thanks to this construction, the solar module 12 is firmly installed in the manhole or access cover 2, or, in his to be addressed to the outside cover surface. The connection line 14 from the solar module 12 to at least one power consumer or to at least one battery or to an accumulator is arranged inaccessible from the outside in the manhole or access cover 2. As can be seen from the drawing, it can be guided through the intermediate space 6 formed between the outer lid wall 4 and the inner lid wall 5 into the region of the shaft wall and from there into the shaft 1. If, as shown, the shaft 1 also has a double wall, the connecting line 14 may be embedded in the gap protected even in this area. Incidentally, the connecting line 14 may be of any desired design, and possibly also a plurality of connecting lines 14 may be present. With the present manhole or access cover 2, the solar energy can be used highly efficiently in a simple and secure manner. The solar module 12 is housed weather resistant. The battery can be charged continuously. A control / charger regulates the capacity and protects the battery from overvoltage. These devices are advantageously housed in a water-protected electrical box. An independent fuse with Fl-switch can additionally protect the maintenance personnel and the components. Even after a two-week period of bad weather, the battery still stores enough power to power a luminaire for hours, allowing for safe working in the shaft or in the well room. The available energy could also be used to operate a heater built into the cover 13 or into the solar module 12, for example a heating wire. This would melt away snow, at least if it does not reach an excessive height, but as is usually the case only in pronounced mountainous situations. Furthermore, it is also conceivable to operate a location transmitter, whereby the shaft 1 can be easily found even under unfavorable conditions. Of course, it is within the scope of the invention according to claim 1 to make the manhole or access cover 2 in detail also different, as shown in the drawing. Instead of the drawn, panel-like solar module 12, a foil-shaped module or foil-shaped photovoltaic cells would also be possible. These could be used instead of the plan shown also in accordance with the cover of FIG. 1 cambered arrangement. The cover 13 could also be multi-part or multi-layered. Theoretically, multiple covers 13 would be conceivable. Ultimately, the exact construction of the manhole or access cover 2 depends on the intended use; that is, the nature, size and location of the space to be closed. The illustrated manhole or access cover 2 is particularly well suited for wells. However, it can just as well be used in water reservoirs or in other lockable containers and tanks that have electricity consumers. However, this list is not exhaustive, especially since the purpose is not the subject of the invention. In any case, both the solar module 12 and the connecting line 14 are housed completely secure. They are protected against the effects of the weather and damage caused by vandalism is virtually impossible. In addition, all components are inaccessible to animals. For example, the solar module 12 can not be damaged by birds. The connection line 14 is not exposed to the danger of being bitten by rodents and the like. And, of course, it can not be demolished either willfully or by natural events. After opening the manhole or access cover 2, however, the solar module 12 and its connecting line 14 are easily accessible to the maintenance personnel. claims 1. shaft or access cover, characterized by at least one photovoltaic cell or by at least one solar module (12), for the conversion of radiant energy into electrical energy.
