The present application provides a micro-electro-mechanical infrared light sensing device and a manufacturing method thereof. The micro-electro-mechanical infrared light sensing device includes a substrate and an infrared light sensing element disposed above the substrate. The infrared light sensing element has a sensing region and a light absorption region which do not overlap each other. The infrared light sensing element includes two infrared light absorption structures, an infrared light sensing layer, and a finger electrode structure. Each of the two infrared light absorption structures includes at least one infrared light absorption layer, and the two infrared light absorption structures are distributed in the sensing region and the light absorption region. The infrared light sensing layer is between the two infrared light absorption structures, and the infrared light sensing layer is located in the sensing region and does not extend to the light absorption region. The finger electrode structure is located in the sensing region, and the finger electrode structure is in electrical contact with the infrared light sensing layer.

This application provides a device and method for lifting, lowering, and bundling cables in uranium leaching well site mining technology. The method includes: a double-spindle mechanism for the lifting pipe and cable, enabling rapid lifting and lowering of the pipe and cable, preventing cable tangling and knotting, eliminating the need to coil the cable on the ground, avoiding cable contamination with soil, and preventing repeated cable lifting and lowering from contaminating the leaching fluid in the well; when lowering is required, the lifting pipe is led out from the first winch mechanism, and the cable is led out from the second winch mechanism, with both the lifting pipe and cable passing through the same end of the bundling device. During the lowering of the lifting pipe and cable through the first and second winches, the bundling device binds the continuously released lifting pipe and cable together, improving the automation level of well site operations, saving labor costs, significantly reducing labor intensity, increasing the efficiency of submersible pump lowering, significantly reducing the contact time between operators and cable components, and improving the safety of submersible pump lowering operations.
