Abstract

An exemplary embodiment of the present invention consists of: 1) a battery-operated immersion pump which is suspended in a filled water cask (barrel), 2) a control element, which is connected to said cask by means of a cable and hose and contains a rechargeable accumulator battery, an electronic charger, a mains-connection plug connection for charging and a pressure-dependent switch which is installed in the pressure line which emerges from the controller and is equipped with a hose sprinkler. 3) After the pump (1) has been suspended in the water container, the switch (2) on the control element (3) is switched on. The pump runs and builds up an (adjustable) pressure in the pressure line (7). Once the set pressure is reached, the pressure-dependent switch (5) switches the pump off. When the sprinkler valve (6) is operated, the pressure in the line (7) falls. The pump (1) starts and runs as long as the sprinkler valve (6) is open. <IMAGE>

Battery-electrically operated hydropneumatic plant irrigation system

Every garden owner knows that the use of the mostly hard and always cold tap water for and therefore, irrigation of plants and crops has adverse effects on growth and prosperity should be omitted. That is why water barrels or basins are provided almost everywhere, in which preferably Rainwater is collected, or which serve to stream or Collect tap water from kitchens, bathrooms and washing machines and store it in order to remove stale, heated water To have irrigation water available. In all cases of this type, however, it is necessary to move out of the described bins To fill watering cans and to carry them - often in large numbers - to the place of consumption. That this work very much laborious and, with almost daily exercise, has negative effects on the spine and joints of the person performing it, is obvious.

The purpose of the present invention is to demonstrate the advantages of sprinkling with tap water using a hose and spray nozzle regarding the physical strain with the optimal use for all plants and crops or to combine rainwater.

In the present embodiment, a battery-powered Immersion pump with a delivery capacity of approx. 10 l / min using a hose and cable for the power supply hung in a filled water barrel.

The hose and cable lead to a control part which is attached to the outer edge of the barrel by means of an integrally formed hanging device and from which the pressure hose provided with the hose shower or spray nozzle branches off on the other hand. The control unit contains a maintenance-free 12 V 2.6 Ah battery, a matching electronic charger (9), a mains connection plug connection (10) for charging, an off switch and a pressure-dependent switch built into the pressure line.

The function sequence as described in the system is as follows:

After attaching the immersion pump (1), the switch {?.) On the control unit (3) is set to the on position. The pump starts up and builds up a pressure that is adapted to the requirements and can be set accordingly in the line leading to the hose shower (4). After the set pressure has been reached, it switches depending on the pressure *; Switch (5) off the power supply to the pump. When actuating the spray valve

(6) at the hose shower the pressure in the line drops

(7), the switch (5) closes the circuit from the battery (8) via the switch (2) to the pump (1), which runs and pumps water until the spray valve (ö) closes.

In this way, it is possible to use the battery power as economically as possible, comfortably and economically. A Deliebig water large numbers of plants with suitable water> -u. Of course, it is also possible to use nut Help this plant plant protection products, weed killers spread among others.

Claims (5)

The attached sketch shows a preferred embodiment (Fig. 1), a detailed drawing (Fig. 2) and a circuit diagram (Fig. 3) of the invention described. Expectations : Plant irrigation system in the sense of the above Description, characterized in that the immersion pump is controlled by a pressure-dependent switch he follows. 2) dto. According to claim 1), characterized in that the power supply from a built in the control part chargeable, maintenance-free 12 V battery. 3) dto. According to claim 2), characterized in that the battery by means of a housed in the control part, mains-operated charger can be charged. 4) dto. According to claim 1) characterized in that a Power consumption by the pump only during the actual irrigation process with the spray valve open takes place because the pump is shut down by means of a pressure-dependent switch when the spray valve is closed. 5) dto. According to claims 1) - 4), characterized in that the control part can be attached to the outside of the barrel by means of an integrally formed suspension device on the edge of the barrel. ^:
