The utility model discloses a multi-channel wavelength division multiplexing optical receiving device, including device main part, its outside is equipped with a plurality of protection components, and the detachable connection between protection components and device main part, be equipped with the limiting component for limiting a plurality of protection components on device main part, device main part includes wavelength division multiplexer body, and the one side of wavelength division multiplexer body is installed with a plurality of terminal ends, and protection components and terminal ends are set up one -to -one correspondence, through with the geographical modularization design of protection components, make every terminal end have independent protection components, more flexible protection each terminal end, therefore, can open or close a certain terminal end alone, and do not influence other terminal ends, to guarantee the protection of every terminal end and the convenience of operation, simultaneously, protection components and device main part adopt detachable connection, can when a certain protection component is damaged, corresponding protection components are dismantled and replaced, to reduce maintenance cost.

The invention relates to the technical field of steel truss lifting, and discloses an integral lifting platform for a large-span steel truss, which comprises a steel truss main body and a lifting machine, the steel truss main body is placed on the lifting machine, and the lifting machine is driven by a main driving device to lift; a flexible assembling assembly and protection assemblies are arranged on the elevator, the flexible assembling assembly is arranged on the elevator, a limiting assembly is arranged on the flexible assembling assembly, the protection assemblies are arranged at the ends of the two sides of the flexible assembling assembly, and filter screen assemblies are installed on the protection assemblies. Through cooperation of flexible assembly and the protection assembly, the problem that existing equipment is poor in adjustability is solved, different lifting sets in the flexible assembly assembly are spliced through clamping protruding heads and sliding grooves, stable connection is achieved through cooperation of the limiting assembly, and the lifting sets can be increased or decreased according to the length of the steel truss; the height of the protection assembly is adjusted through hydraulic lifting of the side protection plate, the sliding hook drives the elastic net and the bearing net for covering protection, the elastic hole and the soft bag buffer falling impact, and flexible assembly and comprehensive protection are integrally achieved.

The utility model discloses a bed surround with height adjusting function relates to bed surround technical field, and two bed surround stand are all provided with screw hole in bed surround stand bottom, and the bed surround stand top is connected with lifting surround pole and auxiliary surround pole respectively. The utility model discloses utilize stepping motor to provide power, make rotating shaft and central column rotation, make power slide column in the power groove on the central column sliding, wherein the power groove is on the central column and is in the shape of spiral ascending, can make lifting surround pole upward movement to the limit support column of utilizing, and the movement of lifting surround pole is limited and is guided, in this process, the guide column slides in the bed surround stand, namely auxiliary surround pole synchronous ascending, in order to adjust the use height, provide more flexible protection, prevent children from turning over or crawling and falling off from the bed, reduce the risk of children's injury, and adapt to the user of different height and different sleep habits.
