A distribution box with drying and dehumidification functions

Abstract

The present invention discloses a distribution box with drying and dehumidifying functions. When the exhaust fan is started, air circulates along the inside of the distribution box body, the air inlet holes and transverse channels of the installation beams, the connecting channels of the connecting pipes, the ventilation holes and ventilation channels of the supporting vertical bars, the connecting pipelines, the exhaust fan, the return air pipeline and the dehumidifier, and the inside of the distribution box body. When the air passes through the dehumidifier with a desiccant bag, the moisture in the air can be efficiently absorbed by the desiccant bag, thereby improving the drying and dehumidification efficiency. When installing electrical components, two installation beams are required. By making the height between the installation beams and the connecting pipe seat adjustable through the first elastic component, the spacing between the two installation beams can be fine-tuned. In addition, the sealing cover and the second elastic component on the supporting vertical bar are provided to achieve sealing coverage of the ventilation holes at the position where the connecting pipe seat is not installed.

Description

Technical Field

[0001] The invention relates to the field of electrical equipment, and in particular to a distribution box with drying and dehumidification functions. Background Art

[0002] A distribution box is a device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet. It is mainly used for power distribution, converting high-voltage electric energy from the transmission network into low-voltage electric energy suitable for various electrical equipment inside the building, and transmitting it to various electrical equipment. Through reasonable circuit design and selection of appropriate electrical components in the distribution box, the electric energy is reasonably and safely distributed to various electrical equipment, ensuring the safe, stable and efficient operation of the power system.

[0003] During the use of the distribution box, it is necessary to keep the inside of the distribution box dry, so as to reduce the possibility of the electrical components getting damp. In the existing distribution box, desiccant dehumidification is adopted. By placing a desiccant bag in the distribution box, the desiccant bag absorbs moisture in the air to achieve the function of drying and dehumidification. However, when using the desiccant bag for drying and dehumidification, the desiccant bag usually absorbs moisture in the surrounding area, resulting in low moisture absorption efficiency.

When the air passes through the dehumidifier 7 with the desiccant bag 73, the moisture in the air can be efficiently absorbed by the desiccant bag 73, thereby improving the drying and dehumidification efficiency; when installing electrical components, two installation beams 43 are required, and different electrical components are required. The distances between the two mounting beams 43 required for the device element are different. At this time, the connecting pipe seats 42 at both ends of the mounting beams 43 can be installed at the ventilation holes 412 at different positions for use.

[0047] The rear side of the top cover 3 is hingedly arranged on the rear side of the top of the distribution box body 1, and a fixing knob bolt 32 is provided in the distribution box body 1, which passes through the top of the distribution box body 1 and is threadedly connected to the top cover 3, so as to fix the top cover 3; at the same time, the desiccant bag 73 is installed in the plug-in frame assembly 72. After opening the top cover 3, the plug-in frame assembly 72 can be taken out to facilitate the replacement of a new desiccant bag 73 for use. The plug-in frame assembly 72 includes a left frame body 721, a right frame body 722, a flexible connecting strip 723 and a third elastic component 724. When a new desiccant pack 73 needs to be replaced, in the process of opening the top cover 3, the rubber sealing plug 74 removes the pressure on the top of the plug-in frame assembly 72, and the fourth elastic component 77 drives the plug-in frame assembly 72 to move upward, and the third elastic component 724 drives the left frame body 721 and the right frame body 722 to rotate in a direction away from each other, thereby facilitating the removal and placement of the desiccant pack 73; in the process of closing the top cover 3, the top of the plug-in frame assembly 72 is pressed downward by the rubber sealing plug 74, so that the fourth elastic component 77 is gradually compressed, and the bottom of the plug-in frame assembly 72 is embedded in the embedding groove 751, gradually overcoming the elastic force of the third elastic component 724 to close.

[0048] The third elastic component 724 includes a first embedded sleeve 7241, a second embedded sleeve 7242 and a third compression spring 7243, so as to drive the left frame 721 and the right frame 722 to rotate and open in a direction away from each other. The fourth elastic component 77 includes a support plate 771, a guide sleeve 772, a lifting shaft 773 and a fourth compression spring 774, so as to achieve the purpose of driving the plug-in frame component 72 to move upward. By providing the first separator 7211 and the second separator 7221, multiple desiccant bags 73 can be separately arranged in the plug-in frame body.

[0049] The connecting pipeline 8 includes a main pipeline 81, an intermediate pipe 82, and a hose 83, thereby connecting the ventilation channel 411 of the supporting vertical bar 41 and the air inlet port of the exhaust fan 5. By setting the electromagnetic three-way valve 9 and the exhaust pipe 10, the air in the distribution box can be extracted to achieve the heat dissipation function. At the same time, because a plurality of air inlet holes 432 communicating with the horizontal channel 431 are set at the bottom of the installation beam 43, the heat near the installed electrical components can be quickly extracted.

[0050] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
