Technical Field
[0001] This invention relates to the field of dehumidification technology for distribution boxes, and more specifically, to a dehumidification device for distribution boxes. Background Technology
[0002] Distribution boxes are characterized by their small size, easy installation, unique technical performance, fixed location, unique configuration functions, lack of site restrictions, widespread application, stable and reliable operation, high space utilization, small footprint, and environmental benefits. They serve as the control center for the rational distribution of electrical energy among various components in the power supply line, reliably receiving power from upstream sources and correctly feeding power to the load. They are also crucial for obtaining user satisfaction with power supply quality. Improving the operational reliability of power distribution boxes is a goal of creating high-quality projects. The uses of distribution boxes include: rationally distributing electrical energy, facilitating circuit opening and closing operations, providing a high level of safety protection, and offering intuitive display. Regarding the conduction state of a circuit, commonly used distribution boxes are made of wood or metal. Metal distribution boxes have a higher protection level, so they are more commonly used. Classified by structural features and application: Fixed panel switchgear, often called switchboard or distribution panel, is an open-type switchgear with a panel covering. The front provides protection, but the back and sides still allow access to live parts. It has a low protection level and can only be used in industrial and mining enterprises with low requirements for power supply continuity and reliability, for centralized power supply in substations. Protective (i.e., enclosed) switchgear refers to a low-voltage switchgear where all sides except the mounting surface are enclosed. The switches in this type of cabinet... Electrical components for protection, monitoring, and control are all installed in a closed enclosure made of steel or insulating material. They can be mounted against a wall or away from a wall. Isolation measures may not be required between each circuit within the cabinet, or grounded metal plates or insulating plates may be used for isolation. Typically, the door and main switch operation are mechanically interlocked. There are also protective tabletop switchgear (i.e., control consoles), with control, measurement, and signal electrical components mounted on the panel. Protective switchgear is mainly used as a power distribution device in process sites. Drawer-type switchgear uses a closed enclosure made of steel plate, with electrical components for the incoming and outgoing circuits installed in removable drawers, forming a system capable of performing a specific type of power supply task. Functional units are separated from busbars or cables by grounded metal or plastic functional plates, forming three areas: busbars, functional units, and cables. There are also isolation measures between each functional unit. Drawer-type switchgear has high reliability, safety, and interchangeability, and is a relatively advanced type of switchgear. Most switchgear refers to drawer-type switchgear. They are suitable for industrial and mining enterprises and high-rise buildings that require high power supply reliability, serving as centralized control power distribution centers. Power and lighting distribution control boxes are mostly enclosed and vertically installed. Due to different usage scenarios, the enclosure protection level also varies. They are mainly used as power distribution devices in industrial and mining production sites.
[0003] To ensure heat dissipation of internal electronic components, distribution boxes are usually equipped with multiple sets of ventilation holes. In humid environments, the flow of moisture in the air can easily cause water vapor to adhere to the wires, which can easily cause short circuits and affect the overall safety of the equipment.

[0012] The technical effects and advantages of this invention are as follows:
[0013] 1. A constant-temperature heating element is installed at the bottom of the heat-spreading matching plate. The constant-temperature heating element is fixed to the bottom of the heat-spreading matching plate by the supporting ribs on the outer wall of the constant-temperature heating element. The constant-temperature heating element heats the air and makes contact with the flowing moisture, causing the moisture to evaporate. By installing multiple sets of constant-temperature heating elements at the bottom of the heat-spreading matching plate, the contact area between the heat-spreading matching plate and the moisture inside the electrical box is increased. At the same time, the overall surface area of the heat-spreading matching plate is increased, avoiding uneven heating of the heat-spreading matching plate, which would affect the dehumidification effect on the electrical box. The user can remove moisture from the area where the heat-spreading matching plate frame is located by rotating the entire plate.

One end of the second connecting arm is fixed to one end of the connecting arm, so that the third and fourth connecting arms are installed on one side of the heating frame. A hinge joint is set at the bottom of the fourth connecting arm. By snapping the hinge seat into the bottom of the hinge joint, the hinge seat is fixed to the inside of the distribution box. By rotating the fourth connecting arm, the hinge joint rotates at the top of the hinge seat to adjust the position of the fourth connecting arm. During the rotation adjustment of the fourth connecting arm, the heating frame rotates with the fourth connecting arm. A heating plate is set at the bottom of the heating frame. The heating plate heats the entire heating frame, removing moisture from inside the distribution cabinet. At the same time, a heat-spreading matching plate is set at the bottom of the heating plate to transfer heat and prevent the heating plate from directly contacting the wiring, which could cause the wiring to age.

[0028] Working Principle: During operation, the first connecting arm 15 is inserted into the connecting seat 14 at the top of the heating frame 1 for fixation. Then, the connecting arm 16 is assembled with the first connecting arm 15. One end of the second connecting arm 17 is fixed to one end of the connecting arm 16, allowing the third connecting arm 18 and the fourth connecting arm 19 to be installed on one side of the heating frame 1. A hinge joint 20 is located at the bottom of the fourth connecting arm 19. By snapping the hinge seat 21 into the bottom of the hinge joint 20, the hinge seat 21 is fixed to the inside of the distribution box. Rotating the fourth connecting arm 19 causes the hinge joint 20 to rotate on top of the hinge seat 21, adjusting the position of the fourth connecting arm 19. During this rotation, the heating frame 1 rotates along with the fourth connecting arm 19. A heating plate 2 is located at the bottom of the heating frame 1, heating the entire frame and removing electrical components.

A constant-temperature heating tube 10 is installed at the bottom of the heat-spreading matching plate 3. The constant-temperature heating tube 10 is fixed to the bottom of the heat-spreading matching plate 3 by the supporting ribs 11 on the outer wall of the constant-temperature heating tube 10. The constant-temperature heating tube 10 heats the flowing moisture, causing the moisture to evaporate. By installing multiple sets of constant-temperature heating tubes 10 at the bottom of the heat-spreading matching plate 3, the contact area between the heat-spreading matching plate 3 and the moisture inside the electrical box is increased. At the same time, the overall surface area of the heat-spreading matching plate 3 is increased, avoiding uneven heating of the heat-spreading matching plate 3, which would affect the dehumidification effect on the electrical box. The user can remove moisture from the area where the frame of the heat-spreading matching plate 3 is located by rotating the fourth connecting arm 19, which allows the user to plan the use of the distribution box reasonably according to its usage.
