Abstract

The solar cell driven garden pump installation proceses current from photovolatic elements in a storage and control electronic control system and that power electric pulses can be generated for operating a magnetic immersion pump even at slight current supply. Pref. the magnetic immersion pump has a pressure container, which prevents sudden accleration of the water vol. in the delivery line at each pump stroke. The delivery vol. and head can varied by the control by capacitor pulse energy output, and by capacitance variations. USE/ADVANTAGE - For garden water supply, filling of rainwater tanks, and garden pond level control, with low-cost water distribution over daylight hours.

Description

Die Erfindung betrifft eine solarbetriebene Pumpanlage zur Wasserversorgung insbesondere von Kleingärten, Auffüllen von Regen­ tonnen und Aufrechterhaltung des Wasserstandes von Gartenteichen aus Brunnen.The invention relates to a solar-powered pump system for Water supply especially of allotment gardens, filling up of rain tons and maintaining the water level of garden ponds from wells.

Die Pumpanlage soll einerseits die individuell benötigte Wasser­ menge pro Tag fördern und andererseits einen kleinen Gartenbrunnen nicht trockenpumpen.On the one hand, the pumping system should have the individually required water promote quantity per day and on the other hand a small garden fountain do not pump dry.

Es ist bekannt, zur Erfüllung dieser Erfordernisse Pumpanlagen so auszulegen, daß der elektrische Strom aus den Photovoltaik- Elementen über Solar-Laderegler in Akkumulatoren gespeichert wird um bei Bedarf aus diesen Akkus Strom für den Betrieb einer Förderpumpe zu entnehmen.It is known to meet these pumping needs to be designed so that the electrical current from the photovoltaic Elements stored in accumulators via solar charge controllers is used to power these batteries for the operation of a Remove feed pump.

Dazu ist allerdings ein erheblicher technischer Aufwand nötig; denn die elektrische Energie wird zunächst von den Solarzellen über einen Laderegler in den Akkus gespeichert. Von dort kann sie dann bei Bedarf über einen Tiefentladeschutz an die Förder­ pumpe weitergeleitet werden. Soll dabei unbeaufsichtigt Wasser gefördert werden so ist eine zusätzliche Intervalleinschalt­ elektronik nötig um kleinere Brunnen nicht trocken zu pumpen.However, this requires considerable technical effort; because the electrical energy is first of all from the solar cells stored in the batteries via a charge controller. From there can then, if necessary, to the conveyor via deep discharge protection pump to be forwarded. Should be unsupervised water an additional interval switch-on is encouraged electronics necessary to avoid pumping smaller wells dry.

Der Erfindung liegt die Aufgabe zugrunde mit möglichst geringem technischen Aufwand eine solarbetriebene Pumpanlage zu reali­ sieren, die über den ganzen Tag verteilt eine individuell benötigte Wassermenge fördert und auch kleinere Gartenbrunnen nicht trockenpumpt. Zudem soll diese Pumpanlage wesentlich kostengünstiger sein, mit weniger bzw. kleineren Photovoltaik- Elementen auskommen und auf den sonst üblichen Speicherakku­ mulator verzichten können. The object of the invention is as small as possible technical effort to realize a solar-powered pump system that are distributed throughout the day individually promotes the amount of water required and also smaller garden fountains not pumped dry. In addition, this pumping system should be essential be cheaper with fewer or smaller photovoltaic Elements get along and on the otherwise usual storage battery can do without the mulator.  

Teil 1Part 1

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die von den Photovoltaik-Elementen gelieferte elektrische Energie elek­ tronisch aufbereitet wird. Die hierzu entwickelte Elektronik benützt zwei (oder auch mehrere) Kondensatoren als Kurzzeit­ speicher. Ist der erste Kondensator durch die Photovoltaik- Elemente auf einen vorgegebenen Spannungswert aufgeladen, so wird eine vorgegebene Menge seiner Energie auf die Spule der Magnetpumpe geleitet und dadurch ein Pump-Hub bewirkt. Zugleich wird der Ladestrom vom ersten Kondensator getrennt und auf den zweiten Kondensator gelegt. Ist dann der zweite Kondensator auf seinen vorgegebenen Spannungswert ausgeladen, so wird wiederum eine vorgegebene Menge dessen Energie auf die Spule der Magnet­ pumpe geleitet und bewirkt einen weiteren Pump-Hub. Gleichzeitig wird der zweite Kondensator vom Ladestrom getrennt und der Lade­ strom wieder auf den ersten Kondensator gelegt. Der Vorgang beginnt von Neuem.This object is achieved in that the of electrical energy supplied to the photovoltaic elements is processed tronically. The electronics developed for this uses two (or more) capacitors for a short time Storage. Is the first capacitor through the photovoltaic Elements charged to a predetermined voltage value, see above a predetermined amount of its energy is applied to the coil of the Guided magnetic pump and thereby causes a pump stroke. At the same time the charging current is separated from the first capacitor and onto the second capacitor. Then the second capacitor is on discharges its specified voltage value, so again a given amount of its energy on the coil of the magnet pump directed and causes another pump stroke. At the same time the second capacitor is separated from the charging current and the charging current again placed on the first capacitor. The process starts again.

Die Pump- bzw. Hubfrequenz der Magnetpumpe hängt somit vom Ange­ bot an Solarstrom ab.The pump or stroke frequency of the magnetic pump thus depends on the requirement offered solar power.

Durch die elektronische Schaltung wird auch erreicht, daß der Spule der Magnetpumpe immer die gleiche Menge an elektrischer Energie zugeführt wird und sich dadurch gleichmäßig starke Pump­ hübe ergeben. Die Förderleistung der Pumpanlage kann durch Änderung der Kapazität der Kondensatoren, durch Regeln der elek­ trischen Energieabgabe der Kondensatoren sowie durch die Leistungsfähigkeit der Photovoltaik-Elemente variiert werden.The electronic circuit also ensures that the Magnetic pump coil always the same amount of electrical Energy is supplied and thereby pump evenly strong strokes result. The pumping capacity of the pumping system can be Change the capacitance of the capacitors, by regulating the elec tric energy output of the capacitors and by Performance of the photovoltaic elements can be varied.

Teil 2Part 2

Erfindungsgemäß wird die Aufgabe auch noch dadurch gelöst, daß in die Magnet-Tauchpumpe ein Druckbehälter integriert wird, der verhindert, daß bei jedem Pump-Hub die gesamte Wassersäule der Förderleitung ruckartig beschleunigt werden muß. Dadurch muß die ruckartig geförderte Wassermenge eines Pump-Hubes nur den Druckbehälter weiter auffüllen, wodurch dann die darin enthaltene Luft weiter komprimiert wird. Die komprimierte Luft drückt dann das Wasser zügig auch durch lange Leitungen. According to the invention, the object is also achieved in that a pressure vessel is integrated into the magnetic submersible pump prevents the entire water column of the Delivery line must be accelerated abruptly. This must the abruptly pumped amount of water from a pumping stroke only the Continue to fill the pressure tank, which then contains the contained Air is further compressed. The compressed air presses then 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 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 are 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 produce water when the sky is completely overcast.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen 1 und 2 dargestellt.An embodiment of the invention is shown in the drawings and 2 shown.
