A down feather type identification device relates to the field of down feather detection equipment and comprises a base, a transverse moving mechanism, a longitudinal moving mechanism, a down feather mounting mechanism and a microscopic imaging mechanism, and a light source is arranged on the base; the down feather mounting mechanism moves back and forth through the transverse moving mechanism and the longitudinal moving mechanism and comprises a base plate, a transparent plate, a mounting groove and a sealing cover. And the microscopic imaging mechanism is arranged above the down feather mounting mechanism and is opposite to the light source so as to observe the down feathers in the mounting groove. The to-be-identified down and feathers are placed in the mounting grooves and then covered with the sealing covers, the different down and feathers are aligned with the light source through back-and-forth movement and then observed through the microscopic imaging mechanism, the accuracy of the detection result is improved, experimental data can be conveniently reserved for subsequent verification, and due to the fact that the mounting grooves are isolated from one another, the accuracy of the detection result is improved. Therefore, multi-type and multi-batch down feather identification can be carried out at the same time without causing confusion, and the detection efficiency is improved.

The present application relates to a kind of high-speed shafting running stability evaluation method of large torque control moment gyro, it is related to testing field, comprising the following steps: the initial high-speed shafting is recorded by photographing microscope, and the surface state of part and bearing is recorded, high-speed shafting is installed, and the difference between the natural frequency and target frequency of debugging combined system is less than ±5% between target frequency;Drive high-speed shafting rotation, after speed stabilizes, drive swing turntable swing, monitor the current, temperature, speed curve and the situation of shafting noise in the running-in period of high-speed shafting in the running-in process on testing device, replace part and retest when abnormal;When to run-in period is qualified, high-speed shafting is removed and disassembled, and the surface of part is observed by photographing microscope, and retest is replaced when abnormal, until running-in process and observation result all meet requirements, the present application has the advantages that the precision of running stability evaluation examination is improved.

The application belongs to the technical field of shield test, and provides a shield indoor test device and method for simulating various complex strata. The model box comprises a bottom plate, a first side plate vertically fixed on the bottom plate, a second side plate hinged on the bottom plate, a third side plate hinged on the bottom plate, a fourth side plate hinged on the bottom plate, and a top plate detachably connected with all the side plates. During the test, the shield machine in the shield system excavates the test block through the round hole, and the test block for simulating different complex strata is replaced for multiple times, so that the shield test for various complex strata is completed. The detachable top plate and the hinged arrangement of the three side plates and the bottom plate realize the replacement of different test blocks, and the test can be stopped and the model box can be opened for observation at any time. Meanwhile, the three-layer structure of the standard test block, the test block and the standard test block realizes the precision simulation of the standard stratum, and improves the test precision.

The utility model belongs to the technical field of laboratory detection, and discloses a full-automatic observation device which comprises a shell, a bearing assembly and a camera, the bearing assembly and the camera are arranged in the shell, the bearing assembly is used for placing a plurality of sample test tubes, and the camera is located above the bearing assembly and used for shooting the sample test tubes. The bearing assembly can drive the sample test tube to move towards or away from the camera; a control system is arranged on the shell and used for controlling rising or falling of the bearing assembly, opening and closing of the camera and the temperature and humidity in the shell. Through the bearing assembly and the camera, an operator can be prevented from repeatedly taking a sample for observation, so that the operator can perform observation and analysis through image data shot by the camera, repeated manual operation is effectively avoided, the observation process is simplified, the pollution risk of the sample is greatly reduced, and the working efficiency is improved. Meanwhile, the temperature and the humidity in the shell can be controlled through the control system, so that the test environment is in a constant-temperature and constant-humidity state, and the test accuracy is improved.
