Technical Field

[0001] This utility model relates to the field of intelligent mining equipment technology, specifically to an automated data acquisition system for heap leaching fields. Background Technology

[0002] Heap leaching fields, as important sites built by some mining companies for metal refining, are large in area, high in elevation, and have steep slopes. Operating equipment in heap leaching fields involves long travel times for personnel, increasing the risk of operational errors and misjudgments, thus impacting work efficiency. Furthermore, low winter temperatures and snow accumulation in some areas pose significant safety hazards to workers. Therefore, it is necessary to develop an automated data acquisition system for heap leaching fields to address these issues. Summary of the Invention

Detailed Implementation

[0017] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0018] Example 1

[0019] An automated data acquisition system for heap leaching fields includes a host computer, a display screen, a PLC controller, sensors, and a data acquisition device. The host computer is electrically connected to a power module and is also electrically connected to the display screen and the PLC controller via wires. The PLC controller is electrically connected to the data acquisition device via wires, and the data acquisition device is connected to the sensor signals via wires. The sensors are installed on the pipelines transporting liquid in the heap leaching field.

[0020] In practical use, the flow and pressure of each pipeline are detected in real time by sensors. The data is then transmitted to the PLC controller via fiber optic cable through a data acquisition instrument. The host computer updates the pressure and flow data of each pipeline in real time according to the preset program and plots them as graphs on the display screen. The flow and pressure of each pipeline can be seen at a glance, thereby achieving a quick and effective judgment of the status of each pipeline, improving work efficiency, and meeting the need for pipeline status visualization in production site management.

[0021] Example 2

[0022] Based on Embodiment 1, this embodiment discloses that the sensor includes a flow sensor for detecting the flow rate of liquid in the pipeline and a pressure sensor for detecting the pressure of liquid in the pipeline.

[0023] Example 3

[0024] Based on Example 2, this example discloses:

[0025] like Figure 1 , 2 As shown, the data acquisition instrument is connected to the pipeline via a connecting mechanism.

[0026] like Figure 1 , 2 As shown, the connecting mechanism includes a housing 5 for holding the data acquisition instrument, two clamps 2, a spherical counterweight base 10, a vertical rod 17, and lateral support legs 11. The bottom of the housing 5 has side plates 16 integrally formed on both sides. The bottom ends of the side plates 16 have vertical rods 17 extending downwards from both ends. The two clamps 2 are installed on the pipe 1. A set of opposite connecting plates 3 are fixed on both sides of the outer wall of the clamps 2. The bottom end of the vertical rod 17 is fixedly connected to the connecting plate 3 by a first bolt 4. The spherical counterweight base 10 is fixedly installed at the bottom of the housing 5. The top of the housing 5 is flat. The side plates 16 are connected to the lateral support legs 11, and the two lateral support legs 11 span across both sides of the pipe 1.

[0027] In this embodiment, two clamps are connected and fixed to the pipe. Then, the vertical rod is connected and fixed to the connecting plate on the clamps. Finally, the lateral support legs are fixed to the ground on both sides of the pipe. Due to the spherical counterweight base, the connection mechanism maintains a low center of gravity and stable posture. Furthermore, in windy conditions, based on the airflow lifting principle of an aircraft wing, this new design is essentially an inverted wing structure with the spherical counterweight base at the bottom, guiding the horizontal airflow. This reduces the upward pressure at the spherical counterweight base to the downward pressure at the top of the casing, ensuring stability of the connection mechanism in windy conditions. The lateral support legs further guarantee the stability of the connection mechanism, enabling the data acquisition instrument to operate safely in the heap leaching field.

[0028] Example 4

[0029] Based on Example 3, this example discloses:

[0030] like Figure 1 , 2 As shown, the side wall of the enclosure 5 is provided with a metal material layer 6, a thermal insulation material layer 7, and a moisture-proof layer 8 from the outside to the inside. The interior of the enclosure 5 forms a data acquisition instrument installation space 9 (the side wall of the enclosure is provided with wiring holes).

[0031] like Figure 1 , 2 As shown, the lateral support leg 11 is a telescopic rod structure, and the bottom end of the telescopic rod structure is provided with a pressure plate 12 for pressing against the ground. By adjusting the length of the telescopic rod structure, the lateral support leg can better adapt to the terrain of the heap leaching field, and the telescopic rod structure can be locked after the pressure plate 12 is pressed against the ground.

[0032] The enclosure design of this embodiment meets the requirements for field operation of the data acquisition instrument in cold winter conditions, enabling the data acquisition instrument to be waterproof and heat-insulated, and avoiding the impact of low temperature on the acquisition effect.

[0033] Example 5

[0034] Based on Example 4, this example discloses:

[0035] like Figure 2 As shown, a door 15 is provided on one side of the enclosure 5, and a louver 18 is provided on the door 15. A sealing plate 19 is fixedly connected to the outer end of the louver 18 by a second bolt. Louvers and sealing plates are also provided on the side wall of the enclosure 5 opposite to the door 15 (not shown in the figure). In summer, the sealing plate is removed to maintain ventilation inside the enclosure and to dissipate heat for the data acquisition instrument. In winter, the sealing plate is installed to block the louvers. Due to the low outside temperature, the data acquisition instrument can rely on the heat conduction and cooling of the enclosure's louvers for cooling during winter use.
