Abstract

A water well and storage tank control system for use in isolated areas that utilizes a solar power source in conjunction with pneumatic pump apparatus for lifting well from a well bore hole for surface deposit in a storage tank. A solar power panel functions to continually charge into a storage battery which, in turn, is periodically applicable to energize a pump/compressor to generate air at increased pressure for conduction down the well bore. An airjet chamber immersed beneath the water level in the well bore receives input of the air at increased pressure and evacuates well water upward through a delivery pipe to a surface storage tank.

Claims

1. Apparatus for automatic control of water flowing from a water well to storage, comprising:

a solar panel having a plurality of soluar cells directed to intercept sun rays to generate a d-c voltage output;

a d-c storage cell receiving input of said d-c voltage output;

pump compressor means periodically energized by said d-c storage cell to provide output of air at increased pressure;

an elongated airjet chamber having upper and lower ends and being disposed below the water level of said well and having a nipple in the upper end for receiving the output of air at increased pressure sealingly connected at an upper extremity, said chamber having inlet holes at a bottom extremity to allow entry of water;

an exit tube extending along the majority of the length of said airjet chamber, said exit tube having at least one air mix hole formed through the upper extremities proximate said airjet chamber upper end;

a surface storage tank; and

a delivery pipe connected between the exit tube at the upper end of the airjet chamber and the surface storage tank to conduct water in response to said air at increased pressure.

2. Apparatus as set forth in claim 1 wherein said pump compressor means comprises:

a d-c motor energized by said d-c voltage output to provide a rotational output; and

a continuous duty compressor receiving said rotational output to produce said air at increased pressure.

3. Apparatus as set forth in claim 1 which further includes:

relay means actuatable to apply said d-c voltage output from the storage cell to energize said pump compressor means; and

control means responsive to a preselected condition for actuating said relay means.

4. Apparatus as set forth in claim 1 wherein said pump compressor means comprises:

a d-c motor energized by said d-c voltage output to provide a rotational output; and

a continuous duty compressor receiving said rotational output to produce said air at increased pressure.

5. Apparatus as set forth in claim 4 which further includes:

relay means actuatable to apply said d-c voltage output from the storage cell to energize said pump compressor means; and

control means responsive to a preselected condition for actuating said relay means.

6. Apparatus as set forth in claim 1 which further includes:

relay means actuatable to apply said d-c voltage output from the storage cell to energize said pump compressor means; and

control means responsive to a preselected condition for actuating said relay means.

7. Apparatus as set forth in claim 6 wherein said control means comprises:

a timer energized by said storage cell and presettable to maintain the relay means actuated for selected periods.

8. Apparatus as set forth in claim 6, wherein said control means comprises:

a level sensor responsive to a selected storage tank level to actuate said relay means.
