Adjustable heat dissipation structure of single-phase single-epitope nonmetal low pressure metering box

Abstract

The invention relates to an adjustable heat dissipation structure of a single-phase single-epitope nonmetal low pressure metering box. The structure comprises a box body. A lower frame of the box body is provided with a push rod, a heat exchange hole and a heat dissipation plate shielding the heat exchange hole. A translation wind control plate is arranged between the heat dissipation plate and the lower frame. One end of the heat dissipation plate is provided with a spring and an end portion of the other end is an inclined plane. A top of the push rod abuts against the inclined plane. The heat dissipation plate and the wind control plate are provided with several through holes. The through holes on the two plates form one-to-one correspondence. Through the through holes, air circulation is performed in an internal portion and an external portion of the heat dissipation plate so that heat in the box body is spilt out. The heat dissipation plate is arranged in a lower portion so that a dustproof function is achieved. The push rod drives the wind control plate to translate and connected areas of the corresponding holes on the two plates are changed so as to change a heat dissipation speed of the box body.

Description

technical field [0001] The invention relates to an electric energy meter box, in particular to an adjustable heat dissipation structure of a single-phase single-meter non-metal low-voltage meter box. Background technique [0002] Most of the traditional electric energy meter boxes are square boxes, such as the box structure shown in "A New Multifunctional Single-phase Electric Energy Meter Box for Anti-Stealing and Lightning Protection" (public number: CN201413348Y). , using a closed frame around; in actual use, this kind of box has some defects, the devices in the box, especially the electric energy meter, have a high calorific value, and necessary heat dissipation measures must be taken in the box. For this reason, an improved technology called "A Electric Energy Meter Box" (publication number: CN204989270U) has been proposed, which shows a heat dissipation structure in which several first through holes are provided on the bottom wall or side wall and correspond to There ...

For this reason, an improved technology called "A Electric Energy Meter Box" (publication number: CN204989270U) has been proposed, which shows a heat dissipation structure in which several first through holes are provided on the bottom wall or side wall and correspond to There is a first spacer, the first spacer and the first through hole form an incomplete closure for heat dissipation, and the first spacer is bent for plugging in wires; although this improved technology can dissipate heat and prevent dust, it will With the increase of wires, the heat dissipation channels are gradually reduced, and it is difficult to ensure a constant heat dissipation effect; moreover, due to different ambient temperatures, the requirements for heat dissipation are also different. When the temperature is high or the heat of the components in the box is large, a faster heat dissipation speed is required. When the air temperature is low or the heat of the components in the box is small, the heat dissipation speed only needs a small heat dissipation speed, but the existing technologies including the above-mentioned disclosed technology are difficult to meet this demand
