8 results about "Spiral joint" patented technology

Spiral forming methods can be used to join edges of a rolled material along a spiral joint to form conical and / or cylindrical structures. Alignment of the edges of the rolled material can be controlled in a wrapping direction as the material is being joined along the spiral joint to form the structure. By controlling alignment of the edges of the material as the edges of the material are being joined, small corrections can be made over the course of forming the structure facilitating control over geometric tolerances of the resulting spiral formed structure.

This invention discloses a dual-purpose installation structure for pole-mounted circuit breakers, relating to the field of power equipment technology. It aims to solve the technical problem that temperature fluctuations affect the fit accuracy between the installation structure and the circuit breaker body, thus impacting service life. Through the synergistic design of a bidirectional shape memory alloy deformable sleeve, adaptive bolts, a spiral joint, and a waterproof heating structure, this invention achieves efficient dual-purpose adaptability to both cold winter and high summer environments. In hot summer conditions, the deformable sleeve expands due to heat, pushing the positioning ring. Combined with the adaptive bolts, the expansion sleeve elastically stretches, preventing rigid compression of metal components. Simultaneously, it drives the spiral joint to secondary compress the rubber layer, enhancing wind resistance and anti-slip capabilities, ensuring stable fixation under high temperatures and strong winds. In extremely cold winter conditions, the deformable sleeve contracts due to phase change, pulling the positioning ring. The adaptive bolts fill the gaps caused by cold contraction, the spiral drainage track guides condensation, and the heated metal mesh prevents icing. Combined with the clamping force of the spiral joint, it avoids the risk of gap widening and slippage.
