Solar pump device for liquids with movable tank

Abstract

A pumping device for liquids is described which comprises a tank for liquids, from which a feeding pipe of a pump with a solar panel draws. The tank consists of a supporting frame with tubular uprights and upper and lower horizontal connection lengths, which supports and surrounds a flexible bag for containing liquids and has an upper connection crossbar of the upper horizontal lengths of the supporting frame, on which the pump with solar panel is mounted. The bag has a lower filling hole or mouth, in which the feeding pipe can be inserted and an overflow hole made in the upper of part of its side wall in position lower than said mouth.

Claims

1. A pumping device for liquids comprising a tank for liquids, from which a feeding pipe of a pump with a solar panel draws, wherein the tank consists of a supporting frame with tubular uprights and upper and lower horizontal connection lengths, which supports and surrounds a flexible bag for containing liquids and has an upper connection crossbar connected to the upper horizontal lengths of the supporting frame, on which the pump with solar panel is mounted.

2. The pumping device according to claim 1, wherein said tubular uprights are made in two parts joined in aligned position by intermediate joining elements.

3. The pumping device according to claim 1 wherein the bag has an upper filling hole or mouth in which the feeding pipe can be inserted.

4. The pumping device according to claim 3, wherein a side wall of the bag has an overflow hole in position under said month.

5. A pumping device according to claim 2, wherein the bag has an upper filling hole or mouth in which the feeding pipe can be inserted.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The features of the present invention will be more apparent from the following description of a practical embodiment thereof, in which:

(2) FIG. 1 shows a first perspective view of a pumping device according to the invention;

(3) FIG. 2 shows a second perspective view of the same device;

(4) FIG. 3 shows a perspective view of the tank of the aforesaid device similar to that in FIG. 1;

(5) FIG. 4 shows a plan view of the tank from the bottom;

(6) FIG. 5 shows an example of a solar panel pump which can be used in the device according to the invention.

(7) The pumping device shown in the drawings comprises a tank 1 for liquids of various kind, in particular water, from which a feeding pipe 2 of a solar panel pump 3 draws, provided with a dispensing pipe 4 connectable to dispensing devices of various kind (not shown), in particular water dispensers for gardening.

(8) The tank 1, shown separately in FIG. 3, comprises a metal frame 5 formed by vertical tubular uprights 6, four by way of example, which are joined on the top in pairs by means of horizontal tubular lengths 7 (FIGS. 1-3), while on the bottom horizontal tubular stretches 16 radially converge towards a confluence area 8, shown in FIG. 4. Each upright 6 is made in two parts joined in aligned position by joining elements 17.

(9) The upper tubular lengths 7 are connected to each other by means of a crossbar 9 (FIGS. 1-3), which supports the solar panel pump 3, shown in FIG. 5, of the type described in Italian application n. 1020155000026737, i.e. comprising a casing 10 containing the pumping element, rechargeable batteries and various electronic devices (not shown in FIG. 5), a solar panel 11 and attachments 12 and 13 for the drawing 2 and dispensing 4 pipes.

(10) The horizontal tubular lengths 7 also work as support for top handles or straps 14 of a flexible bag 15 which can be filled with the liquid to be pumped, in particular irrigation water, which is surrounded by the tubular uprights 6.

(11) The tank 1 is filled through an upper hole or mouth 18 of the bag 15, while the liquid is drawn from the tank by the pump 3 by means of the feeding pipe 2, inserted in the bag 15 through the mouth 18.

(12) An overflow hole 20 is provided in the upper part of the bag 15, under the mouth 18, to limit the filling of liquid and prevent excessive filling from causing leakages of liquid from the mouth of the bag.
