The invention discloses a translational photon optical shutter device capable of being combined with multiple inserts, and the device is characterized in that the device comprises an optical shutter switching assembly, a vacuum chamber, a driving mechanism, and a hinge assembly; the optical shutter switching assembly and the hinge assembly are installed in the vacuum chamber, and the driving mechanism is located outside the vacuum chamber. The driving mechanism drives the optical shutter switching assembly to do reciprocating translation through the hinge assembly and is used for switching control over light passing and light blocking of synchrotron radiation light. An absorber is arranged in the optical shutter switching assembly, the top of the absorber is a light receiving face, and the light receiving face comprises a plurality of inclined faces which are obliquely upward in the incidence direction of synchrotron radiation light and used for blocking the synchrotron radiation light generated by various insertion pieces at the same time. The design of the multi-inclined-plane absorber can block synchrotron radiation light generated by various inserts at the same time, so that the valuable axial space occupied by the device in a light beam line is effectively shortened, and a solid technical basis is provided for the design and layout optimization of the light beam line combined by multiple inserts.

The utility model discloses a settlement measuring head device of a water pipe type settlement meter, which comprises a cylinder, the bottom end of the cylinder is provided with a conical base, the side end of the cylinder is sequentially connected with a breather pipe interface, a water filling pipe interface and a drain pipe interface from top to bottom in the vertical direction, and the water filling pipe interface is connected with a measuring cup arranged at the inner end of the cylinder.

The invention relates to the technical field of deceleration strip power generation and energy recovery, in particular to a deceleration strip composite power generation system based on an improved magnetic lead screw, which comprises a deceleration strip, a reluctance type magnetic lead screw, a coreless axial magnetic flux generator, a magnetic spring and an energy storage device, in the process that a vehicle passes through the deceleration strip, the captured vertically-downward force acts on the magnetic lead screw, the magnetic lead screw is driven to do linear motion under the action of the magnetic spring, the magnetic lead screw can convert low-speed linear motion into high-speed rotating motion, and therefore the coreless axial magnetic flux generator is driven to rotate to generate power, and the power generation efficiency is improved. And finally, the electric energy is stored in the energy storage device to complete the power generation and storage functions. The problems that a generator of a deceleration strip power generation system is low in running speed and low in power generation efficiency are solved, the corresponding structure is optimized, so that the system can work for a long time in the working environment of the deceleration strip, and a new solution is provided for energy recovery.

The application relates to a puncture surgical robot and a sterile cover for an interventional puncture surgical mechanical arm. The sterile cover comprises a protective sleeve, at least one profiling piece and a first fixing structure. The protective sleeve is used for sleeving an execution end; the at least one profiling piece comprises a moving profiling piece, the moving profiling piece has an opening, the profiling piece is communicated with the protective sleeve through the opening, and the profiling piece is used for adapting to the shape of an execution mechanism of the execution end to be sleeved outside the execution mechanism; and the moving profiling piece is fixedly connected with the execution mechanism through a second fixing structure, so that the cross-sectional dimension of the sterile cover in a first direction can be effectively reduced, that is, the redundancy of the sterile cover is reduced, and the risk of infection caused by the puncture needle puncturing the sterile cover is avoided.
