The utility model relates to a kind of geotechnical centrifugal test tunnel excavation simulation box and simulation device, including box, box is filled with simulation foundation, formation loss simulation mechanism is embedded in simulation foundation;Formation loss simulation mechanism includes outer lining plate is inner lining plate, outer lining plate and inner lining plate are enclosed and are horizontally arranged cylindrical, inner lining plate is arranged in the inside of outer lining plate;Formation loss simulation mechanism includes at least two working sections sequentially connected along length direction;Each working section is provided with softening block and water injection pipe;Softening block is against the inner side wall of outer lining plate;The utility model gradually injects water into each working section along tunnel excavation direction by water injection pipe, so that softening block gradually softens along tunnel excavation direction, when softening block softens, volume reduces, the space between inner lining plate and outer lining plate will reduce accordingly, can effectively simulate formation loss process in tunnel excavation process, the disturbance of simulation process to soil is small, and the success rate of test can be improved.

The invention discloses a bridge engineering preloading observation device, and belongs to the technical field of observation devices. Comprising two triangular supports and a plurality of cameras, the upper sides of the two triangular supports are fixedly connected with fixing supports, the fixing supports are fixedly connected with fixing plates through electric push rods, and the fixing supports and the fixing plates are rotationally connected with rotating rods in a penetrating mode; installation assemblies used for installing a plurality of cameras are installed between the two rotating rods located on the fixing support and between the two rotating rods located on the two fixing plates respectively, and each installation assembly comprises two connecting frames and a plurality of first connecting plates. The multiple cameras are adopted for simultaneous observation and distributed on the upper side and the lower side of the bridge, the change of the bridge can be better and more comprehensively observed, in the process, the cameras are in a rotating state all the time, then the observation range of the cameras can be further expanded, and then the data accuracy is improved.

The utility model provides a lifting platform for an observation device, which comprises a sphere observer, an observation camera is arranged in the sphere observer, and an observer fixing frame is arranged at the bottom of the sphere observer; the lifting platform comprises a platform top seat, the platform top seat is connected to the bottom of the observer fixing frame, the lifting platform further comprises a platform base, and the platform base and the platform top seat are connected through a lifting frame body. According to the marine organism observation device, marine organisms are observed through the camera arranged in the sphere observer, the sphere observer is driven by the lifting platform to move up and down, and therefore the effect that the marine organisms at different positions are more comprehensively observed is achieved.

The invention discloses a cardiology department blood sampling detection structure, and relates to the technical field of blood sampling detection, the cardiology department blood sampling detection structure comprises a detection table, a detector and a storage table body, an electric telescopic rod is mounted on the upper side of the detection table, a mounting seat is connected to the bottom of the electric telescopic rod, one side of the mounting seat is connected with the detector, and the detector is connected with the storage table body. And an object placing table body is arranged on the inner side of the detection table. According to the cardiology department blood sampling detection structure, a detector does not need to manually adjust the position of the glass slide, a sample in the glass slide can be more comprehensively and more accurately observed, sample pollution is effectively avoided, the detection efficiency is improved, the glass slide can be stably clamped, the stability during sample observation is effectively improved, and the detection accuracy is improved. According to the blood sampling and detecting structure for the department of cardiology, the problems that the object placing table cannot drive the glass slide to move for more accurate observation, and the glass slide may be polluted due to a manual adjustment mode are solved.
