Moisture-proof distribution box capable of preventing water vapor permeation

Abstract

The invention relates to the technical field of electrical engineering, and provides a moisture-proof distribution box capable of preventing water vapor permeation. The moisture-proof distribution boxcomprises a box body; a sponge block is movably connected to the inner wall of the box body; a stabilizing frame is fixedly connected to the outer wall of the sponge block; and a clamping groove rodis fixedly connected to the outer wall of the stabilizing frame. According to the moisture-proof distribution box capable of preventing water vapor permeation, the distribution box is arranged outdoors; when water vapor is generated due to weather changes, the sponge block absorbs water vapor easily due to the nature of the sponge block; the sponge block continuously absorbs water vapor to enablethe gravity of the sponge block to be increased; the sponge block moves downwards under the influence of gravity, and the sponge block presses acting force above a spiral spring through the clamping groove rod; the spiral spring deforms under the acting force to enable a clamping groove outside the clamping groove rod to be connected with a clamping block; the sponge block and a first linkage rodare used in cooperation to drag a sliding block; the sliding block drives a moving block to move; the moving block moves to enable an arc-shaped closing plate to close an exhaust port, communication between the distribution box and the outside is blocked, and water vapor is prevented from entering the distribution box through gravity change.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a moisture-proof distribution box that prevents water vapor from entering. Background technique [0002] The distribution box is a closed and semi-closed metal cabinet composed of switchgear, measuring instruments, protective appliances and auxiliary equipment. The distribution box is small in size, easy to install, not limited by the site, widely used, and stable and reliable in operation. , high space utilization rate, less land occupation and environmental protection effect. With the development of the times, people's demand for electricity is increasing, and the distribution boxes are constantly increasing. [0003] In the prior art, the distribution box has an exhaust port for heat dissipation, and the distribution box is permanently installed outdoors. In bad weather and in an environment with a large temperature difference between day and night, the exhaust ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the distribution box has an exhaust port for heat dissipation, and the distribution box is permanently installed outdoors. In bad weather and in an environment with a large temperature difference between day and night, the exhaust port may enter rainwater and dew, and the water vapor will contact the distribution box. The live parts inside the box directly affect the work of the distribution box, and the whole body directly changes the normal power consumption of an area. In summer, the temperature difference between day and night is large, the temperature is high during the day and low at night, and the external environment cannot be used for protection and distribution. box, so a moisture-proof distribution box that avoids the entry of water vapor came into being
