This invention relates to a method for fixing silicon steel sheets for inserting the yoke into an AC transformer, belonging to the field of transformer manufacturing technology. It designs a dedicated fixture assembly for fixing the silicon steel sheets for inserting the yoke, including an adjustable I-beam structure, detachable thin square tubes, and fixing plates. The fixing plates are fixedly installed onto the pull plates of the three-phase core columns, using three sets of fixing plates. Two sets of adjustable I-beam structures are used, with the two thick square tubes of the two adjustable I-beam structures connected by a detachable thin square tube. A detachable thin square tube is inserted into the outer end of each of the two thick square tubes of the two adjustable I-beam structures. The upper yoke silicon steel sheets of the three phases are inserted simultaneously, vertically from top to bottom. While inserting the steel sheets, the position of the second thin square tube in the slider is adjusted synchronously, ensuring that the first thin square tube always presses firmly against the already inserted upper yoke silicon steel sheets until the insertion is complete. This invention effectively fixes the inserted silicon steel sheets, preventing overlap and tilting.

The present disclosure relates to the technical field of chemical warehouse management, and discloses a chemical storage method and a chemical storage system. The central area of the bearing table of the storage system is provided with a rotatable object table for placing the chemical to be stored. A moving assembly is connected to the camera assembly. A first display is provided with a first auxiliary strip and a second auxiliary strip on the first preview area of the first display. The first auxiliary strip is a frame-shaped structure coaxially arranged with the first preview area, and the area of the frame-shaped structure is smaller than the area of the first preview area. The second auxiliary strip overlaps the symmetry axis of the first preview area, and the two ends of the second auxiliary strip are connected to the first auxiliary strip. The chemical storage method and the chemical storage system can extract and compare the packaging box and reagent bottle label information, and filter and enter the parameter value from the packaging box and reagent bottle label information according to the logical relationship and weight rules.

This invention relates to the field of wind-resistant technology for high-voltage transmission lines, and discloses a wind-resistant and vibration-damping structure for high-voltage transmission lines. The structure includes two parallel mounting bases with a central support column between them. Multiple suspension arms extending away from the center of the mounting bases are located at their corners. Each suspension arm has a cable clamp at its end for holding the transmission conductor. The structure also includes a first vibration-damping module and a second vibration-damping module. The first vibration-damping module includes a flexible connector and a counterweight. One end of the flexible connector is connected to the mounting base, and the other end is connected to the counterweight, which is located below the center of the mounting base. This invention achieves comprehensive and efficient suppression of wind-induced vibrations in high-voltage transmission lines through an innovative multi-level synergistic vibration-damping design.

This utility model relates to the field of motor technology, specifically a motor end sealing structure, including a base, a first end cover, a first rotary connecting element, and a first sealing element. The base is provided with a first internal connecting step, and the first end cover is provided with a first external connecting step and a first end sealing step. The first end sealing step is located on one side of the first rotary connecting part. A first sealing abutment surface is provided on the side of the base opposite to the first end sealing step. The first sealing element is disposed on the first end sealing step, with its outer diameter sealingly abutting against the first end sealing step and its inner diameter abutting against the first sealing abutment surface. This utility model can effectively prevent external dust, moisture, and other impurities from entering the motor, avoiding the corrosion of internal motor components by impurities, reducing the probability of malfunctions caused by impurity accumulation, and extending the service life of the motor.

This invention relates to the field of mechanical seal technology, specifically to a double-end-face split mechanical seal, comprising a split upper flange, a lower flange, an intermediate shell, a transmission seat, a medium moving ring, a medium stationary ring, an atmospheric moving ring, and an atmospheric stationary ring. The transmission seat is fixed on a rotating shaft, and the intermediate shell is sleeved on the outside of the transmission seat. The upper and lower flanges are respectively connected to both ends of the intermediate shell. The atmospheric stationary ring is installed with the upper flange, and the medium stationary ring is installed with the lower flange. The medium moving ring and the atmospheric moving ring are axially connected to both sides of the transmission seat, and a space is left between them to accommodate an elastic element to provide axial clamping force for the moving ring, pushing the moving ring to fit against the end face of the corresponding stationary ring to form a double-end-face sealing pair. The intermediate shell, upper flange, lower flange, and double-end-face sealing pair together form a sealing cavity. At least one of the intermediate shell, upper flange, and lower flange has a fluid interface communicating with the sealing cavity. This mechanical seal has a simple structure and is easy to install.
