Abstract

The present invention provides relates to a device for introducing high voltage into a plant substrate, the device arranged to be carried by a moving carrier. The device comprises at least two conductive electrodes; at least one pair of insulating guides connected to the at least two conductive electrodes, insulating the electrodes from each other and at least one of them from the moving carrier; at least one connector for attaching the insulating guides into the moving carrier; conductive means for conducting energy from an electrical source to the at least two conductive electrodes.

Claims (48)

1 . Device for introducing high voltage into a plant, the device arranged to be carried by a moving carrier, characterized by comprising

at least two conductive electrodes ( 4 );

at least one pair of insulating guides ( 5 ) connected to the at least two conductive electrodes ( 4 ), insulating the electrodes from each other and at least one of them from the moving carrier;

at least one connector ( 1 ) for attaching the insulating guides ( 5 ) into the moving carrier;

wherein the at least one insulating guide ( 5 ) comprises flexible insulating ropes, cables, hoses or tapes;

conductive means ( 2 ) for conducting energy from an electrical source to the at least two conductive electrodes ( 4 ); and

shields ( 6 ) mounted on the junction between the electrodes ( 4 ) and the insulating guides ( 5 ) to avoid direct contact between the conductive electrodes and the ground.

2 . Device, according to claim 1 , characterized in that

the at least one connector ( 1 ) is a metallic bar with connecting means to couple in a rear part of the moving carrier.

3 . Device, according to claim 1 , characterized in that

at least two conductive electrodes ( 4 ) comprises at least one ground electrode.

4 . Device, according to claim 1 , characterized in that

the conductive means ( 2 ) pass through the insulating guide ( 5 ) and has electrical contact with the electrodes ( 4 ) at a junction between each of the insulating guide and electrodes.

5 . Device according to claim 1 , characterized by the fact that

the shields ( 6 ) are configured to slide along the insulating guides to modify the distance between the electrodes ( 4 ).

6 . Device according to claim 5 , characterized by the fact that

two consecutive shields ( 6 ) comprise an adjustment cable to adjust the distance between the electrodes ( 4 ) by adjusting the cable.

7 . Device according to claim 1 , characterized by the fact that

between two consecutive insulating guides ( 5 ), there is a pair of electrodes ( 4 ) separated by an intermediate insulating shield ( 6 a ).

8 . Device according to claim 7 , characterized by the fact that

wherein each intermediate insulating shield ( 6 a ) comprises an eyelet ( 9 ) for passing a cable; and

in the intermediate insulating shield ( 6 a ) positioned farthermost from the moving carrier, there is fixed a passing cable ( 8 ), which passes through each of the eyelets ( 9 ) and is fixed in the moving carrier.

9 . Device according to claim 8 , characterized by further comprising

a manual or motorized winch ( 7 ) positioned at the connector ( 1 ) or in the moving carrier and connected to the passing cable ( 8 ), wherein the winch ( 7 ) is arranged to, by actuation, draw the passing cable ( 8 ) in order to retract the whole device.

10 . Device according to claim 1 , characterized by further comprising

an insulating mat ( 10 ) mounted covering the electrodes ( 4 ) and/or after the last electrode ( 4 ).

11 . Device according to claim 1 , characterized in that

the conductive electrodes ( 4 ) are arranged at an angle in relation to the insulating guides ( 5 );

wherein the angle is of between 0° and 90°, preferably about 45°.

12 . Device according to claim 1 , characterized by the fact that

the insulating guides ( 5 ) have a rigid shape, being composed of U-shaped or rectangular joints ( 5 a ) coupled among themselves by couplers ( 16 );

wherein each of the U-shaped or rectangular joints ( 5 a ) has an electrode ( 4 ) arranged in each of its perpendicular ends ( 17 ).

13 . Device according to claim 1 , characterized by further comprising

a control device including a voltage sensor, wherein the control device switches the power off the electrodes ( 4 ) when they are contacting or too close to each other.

14 . Device according to claim 1 , characterized by further comprising

a vibration mechanism that causes the electrodes to vibrate in the direction of travel so that the relative speed between the electrodes and the ground is temporarily below and temporarily above the moving carrier's travel speed.

15 . Device according to claim 1 , characterized by the fact that

the insulating guides ( 5 ) have different lengths to vary the distance from the electrodes ( 4 ) to the connector ( 1 ).

16 . Device according to claim 1 , characterized by further comprising

a mechanism for moving the flexible electrode ( 4 ) up and down, comprising:

a spring ( 12 ) connected to the insulating guide ( 5 ) at one end, and connected to an electrode base ( 15 ) at the other end,

wherein the electrode base ( 15 ) holds the flexible electrode ( 4 ) in a position perpendicular to the ground;

the electrode base ( 15 ) has a plurality of gear teeth that cooperates with the teeth of a knob ( 16 ) partially covered by the teeth around its perimeter.

17 . Device according to claim 1 , characterized by further comprising

a mechanism for moving the flexible electrode ( 4 ) up and down, comprising:

a spring ( 12 ) connected to the insulating guide ( 5 ) at one end, and connected to an electrode base ( 15 ) at the other end,

wherein the electrode base ( 15 ) holds the flexible electrode ( 4 ) in a position perpendicular to the ground;

a cam ( 17 , 18 ) for compressing the spring ( 12 ) against the insulating guide ( 5 ).
