Quickly spliced aluminum alloy template
ActiveCN224063905UPlay a supporting and fixing rolequick connectionAuxillary members of forms/shuttering/falseworksForming/stuttering elementsStructural engineeringMachine
The utility model relates to the technical field of quickly-spliced aluminum alloy formworks, and discloses a quickly-spliced aluminum alloy formwork which comprises a main machine body, connecting assemblies and auxiliary fixing assemblies, the connecting assemblies are clamped in the main machine body, and the auxiliary fixing assemblies are distributed in a matrix mode and installed on the two sides of the outer wall of the main machine body; the connecting assembly is arranged, so that a specific splicing groove or a splicing hole can be formed conveniently so as to be quickly connected with other parts, an elastic abutting plate can abut against a front clamping block only by pushing a push rod, the front clamping block is clamped in a groove hole, and a rear elastic abutting plate can also play a certain supporting and fixing role; and an auxiliary fixing assembly and a wear-resistant layer are arranged, the situation that the stability of the device is reduced after an internal connecting assembly goes wrong in the working process of the device is avoided, the hardness and wear resistance of the surface of the device can be remarkably improved through the wear-resistant layer, and the service life is prolonged.

A prefabricated balcony structure and railing
ActiveCN224431615UAchieve initial fixationConvenient for subsequent installation and fixationArchitectural engineeringVeranda
This utility model relates to a prefabricated balcony structure and railing. The prefabricated balcony structure includes a main unit, a base unit, a snap-fit unit, and two docking units. Its advantages are: the main unit and base unit provide an installation benchmark for the railing structure, ensuring basic alignment without repeated fine-tuning, facilitating subsequent installation and fixing; the snap-fit unit engages with the railing structure and base unit via pre-set snap-fit blocks, achieving initial fixing of the railing structure, significantly reducing the cyclical operation of "trial installation-disassembly-re-fixing" in traditional installation, making the installation process simpler and more efficient; the base unit and snap-fit unit work together to restrict the horizontal displacement of the railing structure from the bottom; and the docking units rigidly connect to the railing structure from the side or top, forming a double fixing of "bottom snap-fit + side or top docking," distributing the stress on the railing structure and preventing stability loss due to single-point loosening after long-term use.

An ac-dc hybrid distribution network partition autonomous and mutual aid operation method based on flexible multi-state switch
This invention belongs to the field of AC / DC hybrid distribution network operation and control technology. A method for autonomous and mutual-assistance operation of AC / DC hybrid distribution networks based on flexible multi-state switches includes the following steps: Step S1: Calculate the comprehensive stability index of each node; Step S2: Monitor the comprehensive stability index in real time; Step S3: In the autonomous mode, the SOP within each zone adopts an AC / DC power decoupling control strategy based on dynamic virtual impedance; Step S4: When the power deficit of a zone exceeds a preset proportion of the zone's rated load and the duration exceeds a preset time threshold, the mutual-assistance mode is activated; Step S5: When a system fault occurs, a fault recovery strategy based on model predictive control is adopted; Step S6: Monitor the communication status between the global coordination unit and the control units of each zone in real time. This achieves safe, stable, efficient, and economical system operation, reduces communication dependence, and improves power supply reliability.
