Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet the needs of people's lives and production for water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals. During the water conservancy construction process, the connection of metal sewage pipes needs to be welded and prefabricated before burying.

The second gear rotates to drive the first belt to rotate, the first belt rotates to drive the thick rod to rotate, the thick rod rotates to drive the second belt to rotate, and the second belt rotates to drive the leather rod to rotate. Because of the action of the first gear and the second gear, the leather rod and the thin rod rotate in different directions, and then the two welding pens approach or move away from each other.
