Description

Technical Field

[0001] This utility model relates to the field of smart meter technology, specifically to a smart meter that facilitates heat dissipation. Background Technology

[0002] Electricity meters generate a significant amount of heat during operation, especially in summer. If this heat isn't dissipated promptly, it can shorten the meter's lifespan and, in severe cases, cause a fire, resulting in greater damage. To ensure proper operation, meters are typically housed in relatively enclosed meter boxes. However, with prolonged operation, the temperature inside the box rises, affecting the meter's performance. Therefore, existing meter boxes are equipped with ventilation openings for heat dissipation. However, this allows dust and insects to enter the box, also impacting the meter's functionality. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide an electricity meter that facilitates heat dissipation.

[0004] To address the above problems, the following technical solution is provided: A heat-dissipating electricity meter, comprising a meter body and a casing. The meter body includes an upper accommodating cavity and a lower accommodating cavity. The lower accommodating cavity is separated by a first component to form a left-outlet cavity and a right-outlet cavity. The upper and lower accommodating cavities are opened on opposite sides of the casing. A flow channel is provided between the meter body and the inner wall of the casing, and the flow channel communicates with the upper and lower accommodating cavities. The casing includes an upper shell and a lower shell. The upper shell is detachably connected to the meter body by fasteners. The height of the upper shell is adapted to the upper accommodating cavity. The lower shell includes a component for shielding the lower accommodating cavity. A first housing and a second housing for accommodating a heat dissipation mechanism. The second housing has a heat dissipation channel connected to the flow channel on one side corresponding to the meter body. The first housing and the second housing are integrally formed. The heat dissipation mechanism includes a mounting bracket, a temperature sensor, a micro fan, and a dustproof component. The mounting bracket is located at the connection between the heat dissipation channel and the flow channel. The mounting bracket is detachably connected to the meter body. The dustproof component is hinged to the mounting bracket. The mounting bracket is equipped with a microprocessor for controlling the opening and closing of the micro fan and a drive motor for controlling the rotation of the dustproof component. The temperature sensor and the micro fan are electrically connected to the microprocessor.

[0005] By adopting the above technical solution, the lower shell is removed, the mounting bracket is assembled with the meter body, and then the lower shell is installed. The assembly is simple and convenient. When the temperature sensor detects that the temperature in the circulation channel exceeds the set temperature, the microprocessor controls the micro fan and the drive motor to work respectively. The drive motor controls the dustproof component to rotate, which opens the heat dissipation channel. The micro fan blows the hot air in the outer shell out through the heat dissipation channel, which drives the hot air in the upper cavity to move and dissipate heat through the circulation channel, thereby reducing the temperature inside the meter. Automatic heat dissipation is more efficient than natural heat dissipation and improves the effectiveness of the meter during long-term continuous operation. At the same time, a dustproof component is set at the connection between the heat dissipation channel and the circulation channel to prevent external dust or insects from entering the meter and affecting its operation, thus improving the stability of the meter's operation.

[0007] By adopting the above technical solution, the mounting clip of the dustproof plate is aligned with the mounting hole of the drive gear and inserted, and then the hinge rod is inserted from one end of the sleeve and connected to the mounting frame. The structure is simple and easy to assemble; the drive motor drives the dustproof plate to rotate through the drive gear to open and close the heat dissipation channel, which is convenient to operate.

[0008] The present invention further includes: a plurality of heat dissipation holes provided on the dustproof plate; connection areas for fastening with Velcro provided on both sides of the outer wall of the dustproof plate; and a dustproof cloth that is fastened to the dustproof plate by Velcro on the outer wall of the dustproof plate.

[0009] By adopting the above technical solution, the dustproof cloth can be directly replaced to clean the dustproof panel. The dustproof cloth is washable and replaceable, which is low-cost and easy to operate.

[0010] The present invention further comprises: a threaded hole for mounting a hinge rod is provided on one side of the mounting frame corresponding to the drive motor; one end of the hinge rod is provided with a threaded end adapted to the threaded hole; the other end is provided with an operating end; the operating end is provided with a hexagonal countersunk hole; and the side of the mounting frame corresponding to the operating end is provided with a mounting recess for accommodating the operating end and a through hole for the hinge hole to pass through.

[0011] By adopting the above technical solution, the hinge rod and the mounting frame are detachably connected by threads, making assembly simple and convenient, and facilitating maintenance and replacement.

[0012] The present invention further includes: the mounting bracket includes elastic clamping parts disposed on both sides above the mounting frame, the elastic clamping parts being respectively engaged with the lower walls of the left and right cable outlet cavities.

[0013] By adopting the above technical solution, the elastic clamping part can be directly inserted into the lower wall of the left and right cable outlet cavities to achieve the assembly of the mounting bracket. The assembly is simple, convenient and efficient.

[0014] The present invention further comprises: the upper shell including a transparent display area; a mounting portion is provided on one side of the lower end of the upper shell; the mounting portion is provided with a plug-in hole; a connecting portion is provided on the lower shell corresponding to the mounting portion; the connecting portion is provided with a plug-in card portion adapted to the plug-in hole; the lower shell and the first component are detachably connected by fasteners; the first component is provided with mounting holes adapted to the fasteners; and the lower shell is provided with connecting holes adapted to the mounting holes.

[0015] By adopting the above technical solution, the upper and lower shells are connected by a plug-in connection, and then the lower shell is connected to the meter body via the first component by fasteners, which enhances the stability of the connection. At the same time, the entire shell body is designed as a single flat piece, which has good waterproof and dustproof functions. When assembling the mounting bracket, only one fastener needs to be unscrewed to disassemble the lower shell, while the upper shell remains in the assembled state. There is no need to disassemble the entire shell, which provides better stability and protection and is easy to assemble. Attached Figure Description
