Description

A distribution box with internal fire protection device

Technical Field

The utility model relates to the technical field of distribution boxes, in particular to a distribution box with an internal fire protection device.

Background Art

The distribution box is a type of electrical equipment used to install and protect electrical components. According to different structural characteristics, it can be divided into several categories: fixed panel switch cabinet, protective switch cabinet, drawer switch cabinet and distribution control box. The distribution box has the advantages of small size, easy installation and high space utilization. It is widely used in the fixed protection of circuit control components in various fields. The distribution box is generally composed of a metal box shell and corresponding locking components or control components.

The patent specification with the announcement number CN216720575U discloses a distribution box with wind and sand protection function, including a distribution box, a circular box body and a sleeve. The outer side of the bottom of the distribution box is fixed with a support frame by bolts, and the bottom of the distribution box is penetrated by a sleeve. A connecting rod is installed inside the sleeve through a bearing, and an exhaust fan blade is fixed to the top of the connecting rod by a pin. It is provided with a transparent dust curtain, a winding rod and a pull rod. A person holds the pull rod to pull the transparent dust curtain out of the circular box body, and fixes the pull rod to the bottom of the distribution box. The distribution box can be sealed to a certain extent. When the person opens the box door, he can observe the inside of the distribution box through the transparent dust curtain to prevent wind and sand from entering the distribution box after the box door is opened.

However, in the implementation of relevant technologies, it was found that the distribution box with a wind and sand protection function designed above has the following problems: in the above technical solution, a transparent dust curtain, a winding rod and a pull rod are arranged, and a person holds the pull rod to pull the transparent dust curtain out of the circular box body, and fixes the pull rod to the bottom of the distribution box, so that the distribution box can be sealed to a certain extent. When the person opens the box door, he observes the inside of the distribution box through the transparent dust curtain to prevent wind and sand from entering the distribution box after the box door is opened. However, the distribution box installed outdoors is generally unattended. Once a fire occurs, it is difficult to extinguish it in time, which can easily cause a larger fire. In view of this, a distribution box with an internal fire protection device is provided to overcome the above defects.
