Marking paint applicator apparatus
A marking paint applicator apparatus is disclosed. The marking paint application may include an elongated support structure and a trigger mechanism, a receptacle for holding paint, and an actuating mechanism for selectively controlling release of the paint.
1. A marking paint locator applicator, comprising:
a portable locator, comprising;
an elongate element;
one or more fastener mechanisms located on the elongate element; and
one or more electromagnetic antennas located along a length of the elongated element for generating output signals corresponding to a sensed electromagnetic field emitted from a hidden or buried utility; and
a marking paint applicator, comprising:
a support structure including a fastener apparatus for removably attaching the marking paint applicator to the portable locator fastener mechanisms;
a trigger mechanism;
a receptacle mounted to the support structure for holding an aerosol paint can and positioning a valve stem of the aerosol paint can for spraying paint onto the ground;
an actuating mechanism for controlling the valve stem so as to cause the aerosol paint can to spray paint for deployment on the ground; and
a sensor operatively coupled to the actuation mechanism to provide an output signal upon actuation to the portable locator so as to indicate paint deployment for logging on the portable locator, including time tagging;
wherein the elongate element of the portable locator is substantially the same length as the marking paint applicator.
2. The applicator of claim 1 , wherein one or both of the receptacle and support structure comprise a non-metallic material for minimizing magnetic field distortion of magnetic field signals received by the portable locator.
3. The applicator of claim 1 , wherein the support structure and receptacle are formed as a single integrated unit.
4. The applicator of claim 1 , further including one or more wheels coupled to the support structure.
5. The applicator of claim 1 , wherein the portable locator includes a handle element positioned near the top end of the locator when positioned in a vertical orientation.
6. The applicator of claim 1 , wherein the portable locator includes an activation input to receive a marking paint application signal from the applicator.
7. The applicator of claim 1 , wherein the one or more electromagnetic antennas comprise omnidirectional antennas for measuring magnetic field signals at three orthogonal dimensions.
8. The applicator of claim 1 , wherein the paint applicator includes a matrix array of emission orifices to deploy paint as individual characters, numbers, or symbols.
9. The applicator of claim 1 , wherein the paint applicator deploys paint through a stencil.
10. The applicator of claim 1 , wherein the portable locator further includes a GPS receiver.
11. The applicator of claim 1 , wherein the portable locator further includes an accelerometer.
12. The applicator of claim 1 , wherein the portable locator stores one or more of a buried utility position and depth in conjunction with a dispensed paint time tag.
13. The applicator of claim 1 , wherein the portable locator includes a display for displaying a determined depth of a buried utility along with an indication that paint has been dispensed.
