[0020] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention provides a geomembrane leakage detection device, comprising: A conductive roller 9, which can support a geomembrane 32, is provided directly above the conductive roller 9 with a plurality of conductive plates densely arranged along its length direction and parallel to its axis, an insulating plate is provided between adjacent conductive plates, a plurality of copper wires 33 are densely arranged along its length direction at the bottom of the conductive plate, the gap between the copper wires 33 and the conductive roller 9 is slightly larger than the thickness of the geomembrane 32, and the conductive plate is connected to a high-voltage power supply through a wire; A marking platform 11, which is located on one side of the conductive roller 9 and can support the geomembrane 32, and a plurality of ink marking members 40 corresponding to the positions of the conductive plates are arranged on the marking platform 11, and an electric telescopic rod 13 is arranged directly above the ink marking member 40, and a horizontal buckling plate 12 is arranged at the telescopic end of the electric telescopic rod 13; The controller 26 is electrically connected to the conductive roller 9, each conductive plate, each electric telescopic rod 13, and the high-voltage power supply, and controls the extension and retraction of the electric telescopic rod 13 and the on and off of the high-voltage power supply.

[0021] The geomembrane leakage detection equipment provided by the technical solution mainly includes a conductive roller 9, a marking platform 11 located on one side of the conductive roller 9 and a controller 26. The conductive roller 9 and the marking platform 11 can support a movable geomembrane 32. A plurality of conductive plates densely arranged along the length direction of the conductive roller 9 are arranged directly above the conductive roller 9. Each conductive plate is parallel to the axis of the conductive roller 9. An insulating plate is arranged between two adjacent conductive plates. The insulating plate can be a plastic thin plate to prevent the two adjacent conductive plates from being electrically connected. A plurality of copper wires 33 are densely arranged along the length direction of the conductive plate at the bottom. The dense copper wires 33 constitute a copper brush structure to fully cover the geomembrane 32. The gap between the copper wire 33 and the conductive roller 9 is slightly larger than the back of the geomembrane 32 and smaller than the maximum breakdown gap between the copper wire 33 and the conductive roller 9. Each conductive plate is connected to a high-voltage power supply through a guide. The high-voltage power supply A breakdown voltage is provided for the conductive plate, the copper wire 33 and the conductive roller 9. A plurality of ink marking members 40 are arranged on the marking platform 11. Each ink marking member 40 corresponds to the position of each conductive plate. A vertical electric telescopic rod 13 is arranged directly above the ink marking member 40. A horizontal buckling plate 12 is arranged at the bottom telescopic end of the electric telescopic rod 13. When the electric telescopic rod 13 is extended, the buckling plate 12 is driven to move downward to dock with the corresponding ink marking member 40 to squeeze the geomembrane 32 on the ink marking member 40, so that the ink marking member 40 can mark the geomembrane 32. The controller 26 is electrically connected to the conductive roller 9, each conductive plate, each electric telescopic rod 13 and the high-voltage power supply and controls the extension and retraction of the electric telescopic rod 13 and the on and off of the high-voltage power supply. The conductive roller 9 can be an iron rod or an aluminum roller, and the conductive plate can be an aluminum plate or an iron plate.

[0022] The method of using the geomembrane leakage detection equipment provided by the present technical solution is as follows: when detecting a leak on the geomembrane 32, first pass the geomembrane 32 to be detected through the gap between the conductive roller 9 and each copper wire 33, and the gap between the marking platform 11 and the buckling plate 12 in turn, then connect each conductive plate to a high-voltage power supply, and move the geomembrane 32 at a preset speed. When the leak on the geomembrane 32 passes between the conductive roller 9 and the copper wire 33, the conductive plate corresponding to the leak makes electrical contact with the conductive roller 9. The controller 26 receives a power-on signal and issues a control command to control the electric telescopic rod 13 corresponding to the leak to extend, so that the buckling plate 12 moves downward, and the geomembrane 32 continues to move. When the leak moves to just above the ink marking part 40, the ink marking part 40 and its corresponding buckling plate 12 clamp the geomembrane 32, instantly marking the leak. Then the electric telescopic rod 13 rises, releases the geomembrane 32, and repeats the above steps to detect the next leak.

[0023] The present invention includes at least the following beneficial effects: the present invention detects whether the geomembrane 32 has a hole through the conductive roller 9, the conductive plate, the copper wire 33, and the controller 26. After the conductive plate is connected to the high-voltage power supply, an air gap will be formed between the copper wire 33 and the conductive roller 9 at the hole position, forming an electrical path, so that the controller 26 receives a power-on signal, and the controller 26 controls the electric telescopic rod 13 corresponding to the hole position to extend and drive the buckling plate 12 to move down and work with the marking platform 11 to tighten the marking of the geomembrane 32 and calibrate the hole position. The hole in the geomembrane 32 can be efficiently detected and marked, which is convenient for subsequent repair of the hole in the geomembrane 32 to ensure the integrity of the geomembrane 32 and its anti-seepage effect during subsequent use; a plurality of ink marking parts 40 are provided, and each ink marking part 40 corresponds to a buckling plate 12 that can be raised and lowered separately, so as to reduce the marking range and facilitate more accurate positioning of the hole position.

The ink marking member 40 is movably inserted in the movable hole, and a plurality of first springs 39 are arranged between the bottom of the ink marking member 40 and the bottom wall of the accommodating chamber. Ink is arranged in the accommodating chamber. The annular movable hole is close to the edge of the top wall, so that the ink marking member 40 slides along the side wall of the accommodating chamber, and the movement is more stable; when the electric telescopic rod 13 drives the buckling plate 12 to move downward and dock with the ink marking member 40 and move downward, the first spring 39 pushes the ink marking member 40 and the buckling plate 12 to clamp the geomembrane 32 together for marking; the ink marking member 40 is made of wood, plastic, nylon and other materials, and has the same properties as the pen tip of a marker pen, and can continuously absorb the ink in the accommodating chamber.

[0029] The unwinding roller 3 is used to roll up the geomembrane 32 to be inspected, and the winding roller 1 is used to roll up the inspected geomembrane 32. One end of the unwinding roller 3 can be connected to the output end of the first motor and driven to rotate by the first motor, and one end of the winding roller 1 can be connected to the output end of the second motor and driven to rotate by the second motor. The controller 26 is communicatively connected to the first motor and the second motor to control the operation of the first motor and the second motor.

It extends to the winding roller 1 and is wound by the winding roller 1; after being turned over by the guide roller 19 and the third upper support roller 20, the hole mark originally located below the geomembrane 32 becomes located above or on the outer side of the geomembrane 32, which is convenient for checking and repairing the hole; the telescopic cylinder 24 can directly or indirectly drive the connecting plate 25, the connecting plate 25, the hanging plate 10, the electric telescopic rod 13, the support member 8, and the conductive plate to rise and fall, and then adjust the gap distance between the copper wire 33 and the conductive roller 9, the buckling plate 12 and the marking platform 11, so as to facilitate the adjustment of the geomembrane 32 at the gap; the conductive plate is detachably provided on the support member 8, which is convenient for the inspection and replacement of each conductive plate separately; the support member 8 is detachably provided on the hanging plate 10, which is convenient for the overall disassembly of the conductive plate.

The support member and the hanging plate can be connected or separated by plugging and unplugging the plug plate from the hanging hole, which is convenient for disassembly and assembly.

[0032] In another technical solution, Figure 1 , Figure 2As shown, the geomembrane leakage detection device also includes: a climbing frame 6, which is provided with a horizontal standing board 27 located just above the supporting board 28 and slightly higher than the supporting board 28, a climbing ladder 5 leading to the standing board 27 is provided on the side of the climbing frame 6, and the controller 26 is provided on the climbing frame 6 near the standing board 27. After passing over the guide roller 19 and the third upper support roller 20, the hole mark originally located under the geomembrane 32 and printed by the ink marker 40 becomes located above the geomembrane 32 and displayed on the supporting board 28. The staff climbs to the standing board 27 through the climbing ladder 5 and repairs the hole of the marked geomembrane 32 passing below; the controller 26 is close to the standing board 27 to facilitate the staff to stand on the standing board 27 to operate the controller 26 and control the operation of the equipment.

[0033] In another technical solution, Figure 1 , Figure 2 As shown, the geomembrane leakage detection equipment also includes: a pair of vertical fifth support plates 16, which are located between the first lower support roller 15 and the guide roller 19, a vertical limiting slide 41 is arranged on the second support plate 4, a slider 21 is movably arranged on the limiting slide 41, a lifting roller 22 parallel to the first upper support roller 23 is rotatably arranged on a pair of sliders 21, and the lifting roller 22 is located above the geomembrane 32, and an infrared sensor 17 is arranged on the fifth support plate 16 near the bottom of the limiting slide 41, and the infrared sensor 17 is communicatively connected with the controller 26.

When the wrinkles of the geomembrane 32 are loose, the lifting roller 22 presses the geomembrane 32 below it to move downward to ensure the flatness of the geomembrane 32; when the lifting roller 22 moves downward to drive the slider 21 to move down to the lowest point of the limit slide 41, the infrared ray emitted by the infrared sensor 17 corresponds to the lifting roller 22. At this time, the infrared sensor 17 sends a sensing signal to the controller 26, and the controller 26 then sends a control signal to control the equipment to stop running, so as to prevent the geomembrane 32 from being too loose and affecting the staff's repair of leaks and the normal operation of the equipment, thereby improving safety.

When the hole on the geomembrane 32 passes between the conductive roller 9 and the copper wire 33, the conductive plate corresponding to the hole is in electrical contact with the conductive roller 9. The controller 26 receives the power-on signal and issues a control command to control the electric telescopic rod 13 corresponding to the hole to extend, so that the buckling plate 12 moves down, and the geomembrane 32 continues to move. When the hole moves to just above the ink marking part 40, the ink marking part 40 and its corresponding buckling plate 12 clamp the geomembrane 32, instantly marking the hole, and then the electric telescopic rod 13 rises to release the geomembrane 32.

[0038] The following embodiments are provided according to the geomembrane leakage detection device and the geomembrane leakage detection method of the present invention: A method for detecting leakage of a geomembrane 32 comprises the following steps: The unwinding roller 3 is rotated, and at the same time, one end of the geomembrane 32 to be detected wound on the unwinding roller 3 is sequentially passed through the gap between the conductive roller 9 and each copper wire 33, the gap between the marking platform 11 and the buckling plate 12, the first lower support roller 15, the guide roller 19, the third upper support roller 20, the lifting roller 22, the first upper support roller 23, the support plate 28, the second upper support roller 30, and then extends downward to the winding roller 1, connected with the winding roller 1, and then the winding roller 1 is rotated, and the geomembrane 32 is wound by the winding roller 1, and the geomembrane 32 is continuously moved; When the geomembrane 32 passes through the gap between the conductive roller 9 and each copper wire 33, each conductive plate is connected to a high voltage power supply; When the hole on the geomembrane 32 passes between the conductive roller 9 and the copper wire 33, the conductive plate corresponding to the hole makes electrical contact with the conductive roller 9, and the controller 26 receives the power-on signal and issues a control command to control the electric telescopic rod 13 corresponding to the hole to extend, so that the buckling plate 12 moves down. When the hole moves to just above the ink marking part 40, the ink marking part 40 and its corresponding buckling plate 12 clamp the geomembrane 32, marking the hole instantly, and then the electric telescopic rod 13 rises to release the geomembrane 32; repeat this step to continuously detect and mark the holes in each section of the geomembrane 32; When the hole mark is located on the support plate 28, the winding roller 1 stops rotating, and the staff on the standing plate 27 can repair the hole, and the lifting roller 22 moves down at the same time. If the lifting roller 22 moves down to the lowest point of the limit slide 41, the hole on the support plate 28 has not been repaired, and the infrared sensor 17 sends a sensing signal to the controller 26, and the controller 26 sends a control signal to control the equipment to stop running. After the hole in the geomembrane 32 on the support plate 28 is repaired, the winding roller 1 rotates until the lifting roller 22 rises to the highest position of the limit slide 41, and the unwinding roller 3 starts to rotate again, and the equipment continues to run; Repeat the above steps to detect and repair the leaks in the geomembrane 32.
