The radar rotary table comprises a base, a rotary table, a driving motor, a gear, an encoder and a slewing bearing, the base is fixed to the outer ring of the slewing bearing, the rotary table is fixed to the inner ring of the slewing bearing, the driving motor is fixedly installed on the rotary table, an output shaft of the driving motor coaxially fixes the gear, and the outer ring of the slewing bearing is provided with outer teeth. The gear is meshed with outer teeth on the outer ring of the slewing bearing, and the encoder is installed on the radar rotary table and used for detecting the rotation angle of the rotary table in real time. The radar rotary table is provided with three limiting protection structures which are encoder limiting, electrical limiting and mechanical limiting and play roles in sequence, the safety risk existing in the rotating process of the radar rotary table can be effectively reduced, and the first hollow pipe body and the second hollow pipe body are arranged in the electrical limiting structure so as to communicate the rotary table with the interior of the base. The effect of facilitating cable penetration and layout is achieved.

This utility model relates to the field of medical device technology, and discloses a loading device and a loading system. The loading device is used to accommodate valves and valve clips. The loading device includes a shell with a receiving cavity and a filter structure disposed within the shell. By setting the filter structure, the shell can be divided into a first receiving area for accommodating the valves and valve clips and a second receiving area for accommodating cooling substances. The filter structure can block solids, i.e., ice slag, in the cooling substances from entering the second receiving area, allowing only the liquid in the cooling substances to enter the first receiving area to cool the valves and valve clips. This avoids contact between ice slag and the valves, preventing damage to the valves, thereby achieving the technical effect of improving the stability of valve performance and preventing ice slag from entering the human body, thus improving the stability of the implantation procedure.

The invention provides a turbulent flow generating device with adjustable parameters, which comprises a plurality of generating units arranged in sequence, and each generating unit comprises a lifting base, a mounting plate, an adjusting unit and a wind shielding unit. The mounting plate is arranged on the lifting base, and a plurality of mounting holes are formed in the mounting plate; a plurality of adjusting units are arranged, and the adjusting units are in one-to-one correspondence with the mounting holes; each adjusting unit is used for forming a central ventilation opening in the corresponding mounting hole and adjusting the opening degree of the central ventilation opening; the wind shielding unit comprises a plurality of blocking structures, and the blocking structures correspond to the mounting holes one to one; the blocking structures are used for forming annular ventilation openings with the corresponding mounting holes and adjusting the opening degrees of the annular ventilation openings. The invention provides a turbulent flow generating device with adjustable parameters, and aims to solve the problem that in the prior art, turbulent flow field parameters are inflexible to adjust in the turbulent flow field simulation process.
