Technical Field

[0001] The utility model relates to the technical field of energy metering instruments, in particular to an intelligent energy metering device. Background Art

[0002] Energy metering instruments mainly refer to measuring equipment directly used for measuring energy usage, and the measuring objects are primary energy, secondary energy and energy-carrying medium, such as electric energy meters, water meters, flow meters, etc. Existing energy metering instruments generally have a variety of sensors inside, and they are relatively intelligent.

[0003] However, since there are many sensors inside the intelligent energy metering equipment, there will be many signal lines. These signal lines lack a special storage and organization structure, so it is easy for the signal lines to get entangled with each other, which can easily cause damage and affect the normal use of the energy metering equipment.

[0008] The intelligent heat dissipation structure includes a mounting cover fixedly connected to the rear outer wall of the energy metering instrument body, a heat absorbing fan fixedly installed on the rear outer wall of the mounting cover, a temperature sensor fixedly embedded in the rear of the energy metering instrument body, and a single-chip computer fixedly installed on the side wall of the mounting cover. This achieves the effect of intelligent heat dissipation and reduces the adverse effects of the internal high temperature environment on the energy metering instrument body.

[0009] Preferably, the three signal lines are wound around three cable draw winches in sequence, three cable passing holes are opened on one side of the cable management cover, and one end of the three signal lines passes through the three cable passing holes in sequence.

[0010] Preferably, the self-locking control assembly includes a control shaft connected to the upper inner wall of one side of the cable management cover through a bearing, a worm fixedly mounted on the control shaft, and a worm wheel fixedly mounted on the upper part of the retractable shaft.
