AI Technical Summary

Technical Problem

Traditional distribution boxes suffer from problems such as single threshold protection, delayed response, redundant mechanisms, reliance on power supply, and inflexible heat dissipation structure, leading to unnecessary power outages and low power supply reliability.

Method used

It adopts a thermal expansion drive mechanism, a graded fault warning component, and a heat dissipation adjustment component. Using a shape memory alloy spring as the core power source, it realizes temperature sensing, graded warning, and adaptive heat dissipation. It integrates temperature detection, graded warning, and heat dissipation adjustment functions by using a pure mechanical transmission chain, avoiding reliance on electronic sensors.

Benefits of technology

It achieves coordinated control of graded fault early warning, adaptive heat dissipation and dynamic dust prevention, improves power supply continuity and equipment reliability, avoids unnecessary power outages and electromagnetic interference, and provides a progressive protection strategy from warning to power failure.

Abstract

This invention relates to the technical field of distribution boxes and discloses an intelligent distribution box with graded fault early warning function, including a box body and a box door. Heat dissipation vents are provided on both sides of the box body. A temperature sensing cylinder is fixedly installed inside the box body, and a partition is fixedly installed inside the temperature sensing cylinder. A thermal expansion drive mechanism is provided inside the temperature sensing cylinder on both sides of the partition, and the two thermal expansion drive mechanisms are symmetrically arranged. Each thermal expansion drive mechanism includes a thermal expansion actuator, a linkage component, and a linkage rod fixedly installed inside the temperature sensing cavity. The thermal expansion actuator is used to sense stable changes inside the box body and generate a linear displacement output as the temperature inside the box body rises. This invention integrates the three functions of "temperature detection, graded early warning, and heat dissipation adjustment" into a purely mechanical transmission chain, achieving a high degree of structural integration and adaptive functional coordination. It requires no electronic sensors and has the advantages of direct response and resistance to electromagnetic interference.
