Description
Die Erfindung betrifft eine solarbetriebene Pumpanlage zur Was serversorgung, insbesondere von Kleingärten, zum Auffüllen von Regentonnen und zur Aufrechterhaltung des Wasserstandes von Gartenteichen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a solar-powered pump system for what server supply, in particular allotments, for filling up Rain barrels and to maintain the water level of Garden ponds according to the preamble of claim 1.
Es ist bereits bekannt, daß bei solarbetriebenen Pumpanlagen die elektrische Energie von den Photovoltaik-Elementen entweder direkt zum Betrieb der Pumpe verwendet wird, oder der von den Photovoltaik-Elementen kommende Strom in Akkumulatoren zwischen gespeichert und bei Bedarf der Pumpe zugeführt wird. In beiden genannten Anwendungsarten wird der von den Photovoltaik-Elementen erzeugte Strom mit nur mäßigem Wirkgrad zur Wasserförderung genutzt, was zur Überdimensionierung der Photovoltaik-Elemente zwingt und die Anschaffung solcher Pumpanlagen erheblich ver teuert.It is already known that in solar powered pump systems the electrical energy from the photovoltaic elements either used directly to operate the pump, or that of the Electricity coming in accumulators between photovoltaic elements stored and fed to the pump when required. In both mentioned types of application is that of the photovoltaic elements generated electricity with only moderate efficiency for water production used what to oversize the photovoltaic elements forces and the purchase of such pumping systems considerably ver expensive.
Eine erhebliche Verbesserung des Wirkgrades von solarbetriebenen Pumpsystemen wird in der dem Oberbegriff des Anspruches 1 zugrunde liegenden Offenlegungsschrift DE 33 24 404 A1 vorgeschlagen, wo die von den Photovoltaik-Elementen erzeugte Energie in Kondensatoren gespeichert und als Konstantstromimpuls über die Magnetspule und einen zweiten Kondensator abgegeben wird. Unbefriedigend sind dabei die immer noch relativ hohen Verluste der elektronischen Steuerschaltung, die durch den erforderlichen Zündstrom für Thyristoren sowie dessen Aufberei tung über Transformatoren verursacht werden.A significant improvement in the efficiency of solar powered Pump systems is in the preamble of claim 1 underlying publication DE 33 24 404 A1 suggested where that generated by the photovoltaic elements Energy stored in capacitors and as a constant current pulse emitted via the magnetic coil and a second capacitor becomes. The still relatively high ones are unsatisfactory Losses of the electronic control circuit caused by the required ignition current for thyristors and their preparation caused by transformers.
Der Erfindung liegt die Aufgabe zugrunde, eine solarbetriebene Pumpanlage der gattungsgemäßen Art derart weiterzubilden, daß mit geringem Aufwand die Pumpfrequenz sowie der Wirkgrad erhöht werden. The invention has for its object a solar powered Pump system of the generic type in such a way that the pump frequency and the degree of effectiveness are increased with little effort will.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Dabei wird der von den Photovoltaik-Elementen gelieferte Strom abwechselnd in zwei als Kurzzeitspeicher dienenden Kondensatoren gespeichert. Ist der erste Kondensator auf einen vorgegebenen Spannungswert aufgeladen, so wird eine vorgegebene Menge seiner Energie auf die Spule der Magnetpumpe geleitet und dadurch ein Pumphub bewirkt. Zugleich wird der Ladestrom vom ersten Kondensator getrennt und auf den zweiten Kondensator gelegt. Ist dann der zweite Kondensator auf seinen vorgegebenen Spannungswert aufge laden, so wird wiederum eine vorgegebene Menge dessen Energie auf die Spule der Magnetpumpe geleitet und bewirkt einen weiteren Pumphub. Gleichzeitig wird der Ladestrom vom zweiten Kondensator getrennt und wieder auf den ersten Kondensator gelegt. Der Vor gang beginnt von neuem.This object is achieved by the characterizing features of claim 1 solved. Thereby the of the electricity supplied to the photovoltaic elements alternately in two stored as short-term storage capacitors. Is the first capacitor to a predetermined voltage value charged, so a predetermined amount of its energy is charged conducted the coil of the magnetic pump and thereby a pump stroke causes. At the same time, the charging current from the first capacitor separated and placed on the second capacitor. Then is that second capacitor to its predetermined voltage value charge, so again a predetermined amount of its energy passed on the coil of the magnetic pump and causes another Pump stroke. At the same time, the charging current from the second capacitor separated and put back on the first capacitor. The before course begins again.
Die Pump- bzw. Hubfrequenz hängt vom Angebot an Solarstrom ab. Durch die Schaltungsauslegung wird auch erreicht, daß der Spule der Magnetpumpe immer die gleiche Menge an elektrischer Energie zugeführt wird, und sich dadurch gleichmäßig starke Pumphübe ergeben. Die Förderleistung der Pumpanlage kann durch Änderung der Kapazität der Kondensatoren, durch Regeln der elektrischen Energieabgabe der Kondensatoren, sowie durch die Leistungsfähig keit der Photovoltaik-Elemente variiert werden.The pump or stroke frequency depends on the supply of solar power. The circuit design also ensures that the coil the magnetic pump always the same amount of electrical energy is fed, and thereby evenly strong pump strokes surrender. The delivery rate of the pumping system can be changed the capacitance of the capacitors, by regulating the electrical Energy output of the capacitors, as well as through the powerful speed of the photovoltaic elements can be varied.
Durch Einstellung der Energieabgabe der Kondensatoren kann das Pumpsystem auch optimal an die Förderhöhe angepaßt werden. Die Magnet-Tauchpumpe kann auch mit einem Druckbehälter versehen werden, der verhindert, daß bei jedem Pumphub die gesamte Wassersäule der Förderleitung ruckartig beschleunigt werden muß. Dadurch muß die ruckartig ausgestoßene Wassermenge eines Pump-Hubes nur den Druckbehälter weiter auffüllen, wodurch die darin enthaltene Luft weiter komprimiert wird. Die komprimierte Luft drückt dann das Wasser zügig auch durch lange Leitungen. This can be done by adjusting the energy output of the capacitors Pump system can also be optimally adapted to the delivery head. The magnetic submersible pump can also be equipped with a pressure tank, which prevents the entire water column from pumping the delivery line must be accelerated suddenly. Thereby must be the abruptly expelled amount of water from a pump stroke just continue to fill the pressure tank, causing the inside contained air is further compressed. The compressed air then presses the water quickly through long pipes.
Magnetpumpen, die mit Wechselstrom oder getaktetem Gleichstrom arbeiten, sind Stand der Technik.Magnetic pumps using alternating current or pulsed direct current work are state of the art.
Photovoltaik-Elemente, wie sie hier verwendet werden können, sind handelsüblich.Photovoltaic elements as they can be used here are commercially available.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere auch darin, daß mit geringerem technischen und finanziellen Aufwand eine solarbetriebene Pumpanlage entstehen kann, die auch in der Lage ist, bei völlig bedecktem Himmel noch Wasser zu fördern.The advantages achieved with the invention also exist in particular in that with less technical and financial effort a solar-powered pump system can also be built in the It is able to pump water when the sky is completely overcast.
Ein Ausführungsbeispiel der Erfindung ist in den Fig. 1 und 2 dargestellt.An embodiment of the invention is shown in FIGS. 1 and 2.
Dabei zeigt Fig. 1 eine elektronische Schaltung mit einer Solarzelle 1 und einer Magnetpumpe 2.Here, FIG. 1 shows an electronic circuit with a solar cell 1, and a solenoid pump 2.
