This utility model relates to the field of explosion-proof electrical technology and discloses a drainage protection structure for an explosion-proof distribution cabinet. The structure includes a base, a distribution unit body fixedly connected to the upper surface of the base, a distribution unit internally housed within the distribution unit, a drainage trough inside the distribution unit, a
water collection tank fixedly connected to the lower surface of the distribution unit, a one-way drain valve fixedly connected to the lower surface of the
water collection tank, a hinge fixedly connected to the outer wall of the distribution unit body, and a distribution door fixedly connected to the outer wall of the hinge. A sealing
assembly is located inside the distribution door, including a sealing strip disposed inside the distribution door, and a spring fixedly connected to the inner wall of the distribution door. In this utility model, the drainage trough's design with one end higher than the other and the one-way drain valve allow for centralized drainage of condensate, preventing water accumulation. The two
layers of sealing strips, spring, and push plate enhance the sealing performance.
