Abstract: The present invention discloses a method of measuring longitude deformation of blades. The radiation and rotation speed of the blade are collected by an optical probe and a synchronized rotation sensor. The stretch of the blade is able to be determined by the obvious change in the light intensity detected by the optical probe. The precision servo motor keeps driving the optical probe to move upward. The collected radiation is compared with the radiation collected on the previous point. The stretch of the blade is calculated based on position of the blade tip which is determined by the time when the high level radiation from the blade is disappeared. The longitude deformation of the blade is calculated by plugging the stretch into the deformation equation. Mapping the calculated deformation with the number of the blade calculated with rotation speed synchronizing signals to achieve the deformation of all the blades.

Abstract: A device for measuring surface-temperature of a turbine blade, the device including a probe having a front-end mirror for receiving infrared radiation of a surface on the blade, a collimation lens for refracted the infrared radiation, a PD detector to receive the infrared radiation, and a focal-length servo; and a radial-scanning servo connected to the probe. The front-end mirror, the collimation lens, and PD detector are disposed along the optical axis of the collimation lens. The focal-length servo is adapted to move the collimation lens along the optical axis of the collimation lens. The radial-scanning servo is adapted to move the probe along the optical axis of the collimation lens. The device of the invention is capable of accurately targeting a particular point on the blade having an irregular shape for temperature measurement to accurately detect the temperature distribution on the surface of the blade.

Abstract: An intelligent thermoelectric-battery integrated structure, which belongs to the field of new energy device, is provided. The structure intelligently controls the temperature of the single cells inside the battery pack by means of direct contact, so as to reduce the temperature and cut off the occurrence of thermal runaway from the root cause. In addition, the Seebeck voltage generated based on the temperature difference can directly store energy inside the battery when charging, and can increase the overall output voltage when discharging. The advantage of this structure solves the contradiction between the difficulty of achieving high energy density and high safety performance for traditional batteries at the same time, and provides a practical solution for the development and utilization of a new generation of high-performance batteries.
