Abstract

A device for monitoring the physical characteristics of groundwater or other fluids. The sampling device includes a frame, a hanger for suspending the device from the wellhead, a service cable storage reel mounted for rotation on the frame, a handle for rotating the reel, a lock for preventing rotation of the reel with respect to the frame and a guide for directing the service cable from the reel into the wellhead. The device also may include a service cable which includes discharge hose and an electrical cable which are bonded together to function as a unitary cable and a cable block for sealing the lower end of the electrical cable to prevent the incursion of groundwater.

Claims

1. A device for monitoring the physical characteristics of ground water or other fluids and adapted for use with a well having a wellhead, the system comprising;

a frame including means for suspending the device from the wellhead;

a storage reel mounted for rotation on the frame;

means for rotating the reel;

means for locking the reel with respect to the frame; and

means for guiding a service cable from the reel to the wellhead.

2. The device of claim 1 wherein the means for suspending includes a protrusion adapted to extend into the top of the wellhead.

3. The device of claim 2 wherein the means for suspending includes a hanging bar and wherein the protrusion extends from the bar.

4. The device of claim 3 wherein the bar includes a plurality of spaced openings and the means for suspending includes at least two pins adapted to be removably mounted in the holes.

5. The device of claim 1 wherein the means for suspending includes a hook adapted to engage the top of the wellhead.

6. The device of claim 1 wherein the means for rotating the reel includes a handle attached to the reel.

7. The device of claim 6 wherein the means for rotating includes an electric motor operable connected to the reel.

8. The device of claim 1 wherein the means for guiding includes a roller mounted for rotation on the frame.

9. The device of claim 1 wherein the means for guiding includes a channel member adapted to be slidably engaged by the service cable.

10. A device for monitoring the physical characteristics of ground water or other fluids and adapted for use with a well having a wellhead, the system comprising:

a frame including means for suspending the device from the wellhead, the suspending means including a hanging bar and at least two pins removably mounted to the bar and adapted to engage the top of the wellhead;

a storage reel mounted for rotation on the frame;

a handle for rotating the reel;

means for locking the reel with respect to the frame;

a service cable including a discharge tube providing a passageway for the transport of fluid, an electrical cable including insulated electrical conductor means, and integral support cable means for supporting the service cable and the pump wherein the discharge tube and the electrical cable are longitudinally bonded; and

a roller mounted for rotation to the frame for guiding the service cable from the reel to the wellhead.
