A forging stress detection device
ActiveCN224286190Uavoid displacementisolation impactForce measurementWork holdersClassical mechanicsScrew thread
This utility model discloses a forging stress detection device, relating to the field of materials science and technology. The device includes a base with a support frame fixedly connected to its top. A fixing mechanism is mounted on the base, and a detection mechanism is mounted on the support frame. The fixing mechanism includes a limiting ring, with a threaded rod rotatably connected to the inner wall of the limiting ring. By incorporating a soft pad, rotating a knob causes the threaded rod to rotate, which in turn moves a threaded cylinder downwards along the threaded rod. This threaded cylinder then pulls a connecting rod downwards, which in turn pulls the moving blocks closer together. The soft pad, which clamps and fixes the forging, effectively isolates it from external vibrations and the vibrations of the testing equipment, preventing displacement due to insufficient fixation and ensuring the accuracy of the test results.

A portable infrared spectrometer suitable for VOCs detection
ActiveCN110715904Bscan stableStable mechanical structureMaterial analysis by optical meansBeam splitterOptical pathlength
The present invention relates to a portable infrared spectrometer, and in particular to a portable infrared spectrometer suitable for VOCs detection. It comprises a support rod and an angle mirror 1 and an angle mirror 2 arranged at both ends of the support rod, a rotating bearing is arranged in the middle of the support rod, and the rotating bearing can be driven to rotate by a motor to drive the support rod to rotate; an end reflector 1 and an oblique reflector 1 are arranged below the angle mirror 1; an end reflector 2 and an oblique reflector 2 are arranged below the angle mirror 2; a beam splitter / compensator is vertically arranged between the oblique reflector 1 and the oblique reflector 2, a laser emitting device is arranged on one side of the beam splitter / compensator, and a long optical path absorption device is arranged on the other side of the beam splitter / compensator. Therefore, the present invention has the following advantages: 1. The mechanical structure is stable and suitable for portable detection occasions. 2. A structure in which the optical path is equal to 8 times the mechanical stroke is realized, so that under the same spectral resolution, the mechanical stroke is greatly reduced, making the spectral scanning more stable.

Laser radar and automatic driving equipment
PendingCN119596274Asave computing resourcesreduce artifactsElectromagnetic wave reradiationTransceiverRadar
The invention relates to the technical field of radars, and provides a laser radar and automatic driving equipment. The laser radar comprises a first transmit-receive module, a second transmit-receive module and a galvanometer. The first transceiver module and the second transceiver module are both used for emitting emergent laser and receiving echo laser, the echo laser is laser returned after the emergent laser is reflected by an object in a detection area, and the galvanometer is used for reflecting the emergent laser emitted by the first transceiver module and the second transceiver module and then emitting the emergent laser to the detection area. Meanwhile, the first receiving and transmitting module and the second receiving and transmitting module are used for reflecting the echo laser and transmitting the reflected echo laser to the corresponding first receiving and transmitting module; the detection areas corresponding to the more than two first transceiver modules are spliced into a scanning area, and the detection area corresponding to the second transceiver module is at least partially overlapped with the scanning area. The detection area corresponding to the second transceiver module is specially used for overlapping with the scanning area, a large-area ROI area can be realized, and the ROI area is formed by adopting a physical overlapping mode, so that network broadband occupation and computing resources are saved.

A method for detecting artepillin c in brazilian propolis using a thin layer scanner
The application discloses a method for detecting artepillin C in Brazilian propolis by using a thin layer scanner and belongs to the field of traditional Chinese medicine quality detection. The method specifically comprises the following steps: sucking the pretreated propolis sample solution and spotting the sample solution on a thin layer chromatography silica gel plate; adopting a mixed system of petroleum ether, ethyl acetate and formic acid with a volume ratio of (8-14):(3-6):(0.2-1) as a developing agent, flowing the developing agent through the fixed phase with the propolis sample solution, and drying to obtain a sample to be measured; scanning the chromatographic spots in the sample to be measured by using a thin layer scanner, testing the wavelength of 290-320 nm, the reference wavelength of 400-800 nm, and obtaining the absorbance integral value of the sample to be measured; and converting the absorbance integral value with an artepillin C standard curve to obtain the content of artepillin C in the sample to be measured. The method can simultaneously determine the content of artepillin C in multiple batches of propolis samples, the chromatographic peak of artepillin C is well separated and stable in scanning, and the method has the advantages of fast detection speed and low cost.
