This invention discloses a voltage detection and grounding drone and its control method, applied in the field of power system maintenance technology. It includes a drone and a voltage detection and grounding device located beneath the drone. The voltage detection and grounding device consists of an insulating rod, a locking mechanism, and a clamping mechanism. The clamping mechanism is located at one end of the insulating rod, which is fixed to the drone via the locking mechanism. The locking mechanism includes a rear locking mechanism located under the drone's belly, consisting of a vertical slide rail, a rear locking baffle, and a motor mechanism. The motor drives the baffle to move up and down along the slide rail, thereby moving the insulating rod. The clamping mechanism uses a V-shaped fixing plate with a voltage detection and grounding module at the bottom, including a voltage detection sensor, a grounding unit, and a clamping ratchet. The ratchet can rotate laterally to fix the cable within the V-shaped opening, realizing voltage detection and grounding operations. This invention solves the technical problems of low efficiency in existing voltage detection and grounding methods, high safety risks and costs associated with manual operations, and limited applicability of drones for attaching and removing grounding wires.

This invention discloses a process for the recovery and resource utilization of wastewater and waste gas generated during silver powder production. It effectively recovers and treats four types of wastewater generated during silver powder production: organic-free ammonium nitrate wastewater, organic-free sodium nitrate wastewater, sodium nitrate wastewater containing organic matter, and ammonium nitrate wastewater containing both organic matter and sodium nitrate. The invention effectively recovers and treats all four main types of wastewater and two types of waste gas generated during silver powder production, converting them all into the necessary production materials such as ammonia, concentrated nitric acid, dilute nitric acid, and sodium hydroxide, thus achieving complete recovery and utilization of all wastewater and waste gas.
