This invention relates to the field of automated assembly technology and discloses an automated assembly equipment and method for hydraulic cylinders, including an assembly table. The top surface of the assembly table is provided with a piston turning assembly for moving a piston to a workstation. Above the assembly table is a piston adjusting mechanism for workstation transfer of the piston. Above the assembly table is a piston outer sealing ring fitting assembly for fitting an outer sealing ring onto the piston surface. This invention not only achieves continuous piston transport, workstation transfer, and sealing ring assembly through a fully automated design, including an electric conveyor belt, turntable, and cylinder drive assembly, but also significantly reduces manual intervention, improves overall assembly speed and production efficiency. The drive device and transmission components ensure accurate piston positioning at each workstation and precise fitting and insertion of the sealing ring, effectively reducing assembly errors.

The present application relates to the field of strong light search for ships, and specifically discloses a ship sea sweeping lamp and its production process, which includes a light source module, a control device and a shell assembly, wherein the shell assembly includes a base, a bracket rotatably connected to the base, and a shell fixedly connected to the bracket, wherein the shell is provided with a plurality of heat dissipation holes near the rear end, and the shell is provided with a plurality of groups of reflection areas near the front end, wherein the reflection areas include a plurality of waist-shaped grooves and a plurality of reflection grooves, and the plurality of waist-shaped grooves and the plurality of reflection grooves surround a circle. By providing waist-shaped grooves and reflection grooves, the present application can effectively destroy the continuity and regular shape of the shell, thereby changing the radar reflection characteristics of the lamp body, and this scattering effect helps to achieve the radar stealth effect of the lamp body.

The present invention relates to the field of medical technology, and in particular to a highly stable vitamin B6 injection and a preparation method thereof. In the present invention, each 1000ml of the highly stable vitamin B6 injection contains, in addition to 100g of vitamin B6, 2.5-3.5g of an antioxidant, 3.6-4.5g of an antidegradant and 1.2-1.5g of a stabilizer. The antioxidant is one or more of sodium bisulfite, sodium pyrosulfite and sodium thiosulfate, the antidegradant is N-acetylcysteine, and the stabilizer is taurine and meglumine. The highly stable vitamin B6 injection provided by the present invention has high stability, and after undergoing 6 months of accelerated stability testing, the content of related substances is less than 0.05%, which is far below the pharmacopoeia standard.

This invention discloses an intelligent control piped direct drinking water circulation and return device, including a water storage tank. A drive component is installed inside the water storage tank, and a power supply component is installed on one side of the water storage tank. The power supply component is electrically connected to the drive component. In this invention, by setting up the drive component, when a user opens and closes the tap supplying direct drinking water, the pressure inside the pipe changes due to water hammer. At this time, the piston located in the connecting pipe is driven by the pressure change caused by the water hammer, which, in conjunction with the connecting rod and the rotating rod, causes the lever to drive the sliding sleeve to rotate. Thus, when the user uses direct drinking water, the pressure plate in the water storage tank discharges the water from the storage tank, transporting the stagnant water in the storage tank to the water supply pipeline for other uses or for further water treatment, without the need for an additional drive device to drive the stagnant water.
