The utility model provides an intelligent full-automatic transformer oil sample needle cylinder sampling device, which relates to the technical field of electrical equipment operation and maintenance, and comprises a case, an adapting and sampling unit and a control unit, the adapting and sampling unit comprises a component adapted to different oil taking ports, a valve and a needle cylinder sampling component, the control unit realizes sampling process control, parameter setting, state switching and data recording and displaying and supports wireless transmission, the whole sampling process is automatically controlled by a single chip microcomputer through the intelligent control unit according to preset programs and parameters, and the sampling efficiency is improved. Comprising switching of valves, movement of a needle cylinder piston and the like, manual operation is not needed, the sampling precision is improved, the electromagnetic force of an electromagnet is precisely controlled by an electromagnetic control unit, the needle cylinder piston is driven to move precisely, and compared with existing equipment which can only use a peristaltic pump for sampling, the error range of the sampling amount can be controlled within the extremely small range; and the sampling precision is greatly improved.

This invention relates to an early warning method for bilateral force imbalance during strength training, aiming to solve the problem that exercisers often find it difficult to detect bilateral imbalances in current weight training equipment, leading to safety hazards such as muscle strains. The technical solution includes a detection mechanism for bilateral mechanical data. This mechanism comprises a tension cable and two side plates connected to the ends of the cable. The first side plate has a corrugated anti-slip texture on its outer side and an adhesive layer on its inner side to ensure it adheres to the palm. The second side plate has an acoustic-optical-electric display device on its outer side and an adhesive layer on its inner side to ensure it adheres to the back of the hand. A pressure sensor is located at the bottom of the corrugated anti-slip texture. A force sensor is located on the tension cable. The acoustic-optical-electric display device includes two sets of gradient light strips. The first gradient light strip is connected to the pressure sensor via a controller, and the second gradient light strip is connected to the force sensor via a controller. The advantage is that the pressure sensing circuit detects the weight distribution on both sides, while the acoustic-optical-electric device provides real-time early warning, protecting the exerciser and reducing safety hazards.
