AI Technical Summary
The end caps of existing water storage tanks suffer structural fatigue damage during transportation due to bumpy movements, affecting sealing performance and service life, and posing safety hazards.
The water tank head adopts a double-layer structure design, with the inner and outer heads consisting of an inner liner and an outer reinforcing mesh, respectively. The inner and outer reinforcing meshes are connected and welded together through slots. The inner reinforcing mesh has a larger mesh count than the outer reinforcing mesh, which enhances the structural stability.
It improves the structural reliability and service life of the water tank head, enhances its ability to withstand impact loads, reduces deformation, ensures sealing performance, and improves transportation safety.
