A rapid detection kit for thiamethoxam colloidal gold

ActiveCN224278112Uensure ordereasy to findSealingLocking devicesBiochemical engineeringThiamethoxam
This utility model discloses a rapid detection kit for thiamethoxam colloidal gold, comprising a main body, a fixing mechanism, an installation mechanism, and a closing mechanism. The fixing mechanism includes a shelf and a reset plate, the installation mechanism includes a test plate and test tubes, and the closing mechanism includes a sealing gasket and a closing cap. With the cooperation of the above mechanisms, this design of the device helps to maintain the orderly storage of the multiple internal components of the kit, reducing the possibility of confusion and erroneous operation. Users can easily find the required test boxes, test tubes, and reagent bottles, improving work efficiency. In addition, this device can fix the components inside the main body, making it convenient to carry the components inside the main body.

High-altitude cable quick fixing structure

PendingCN122292216AScientific and reasonable structureeasy to useAir pumpSteel frame
This invention belongs to the field of power engineering technology, and in particular to a rapid high-altitude cable fixing structure, comprising an I-shaped steel frame. The surface of the I-shaped steel frame is provided with a movable component, which includes a rear movable plate located below the I-shaped steel frame. When the air pump is running, gas is injected, driving the front L-shaped movable plate to move via a connecting rod. When the air pump is running, gas is extracted, pulling the rear movable plate to move. This alternation achieves intermittent movement of the entire structure on the I-shaped steel frame. When the front L-shaped movable plate moves, it drives the irregular plate, causing the L-shaped fixing hook plate to rotate around it. When the rear movable plate moves, the L-shaped fixing hook plate rotates under gravity to below the cable. As the entire structure moves, the cable is fitted and fixed within the L-shaped fixing hook plate, achieving rapid and stable fixing of the cable at high altitude.

A method for intelligent operation and maintenance risk early warning of power transmission equipment in harsh environments

This invention belongs to the technical field of power system monitoring and relates to an intelligent operation and maintenance risk early warning method for transmission equipment in harsh environments. The method includes the following steps: synchronously collecting sensor and meteorological data; calculating a dynamic benchmark based on an association model and differentially generating state residual signals; monitoring vibration residuals and triggering a hardware interrupt when conditions are met to synchronously capture high-frequency waveforms of leakage current and temperature during fault transients; extracting feature vectors through dimensionality reduction encoding of the data and generating residual coupling fingerprints by combining them with timestamps; mapping the fingerprints to state trajectories and calculating their geometric similarity to standard templates in a fault topology library to generate targeted early warnings; and dynamically adjusting the acquisition parameters and updating the association model based on the early warning results. This invention solves the problem that existing transmission equipment monitoring methods struggle to isolate environmental interference, leading to low early warning reliability and difficulty in accurately characterizing faults.
