Description

Technical Field

[0001] The present invention relates to the technical field of electric energy meter boxes, and in particular to a multifunctional safety electric energy meter box. Background Art

[0002] An electric energy meter box refers to a housing used to install an electric energy meter.

[0003] For example, Chinese patent CN110425200B discloses a power box with a weight-balanced clamp that is hung on a utility pole. The box comprises a power box body, a door, heat dissipation holes, a welding plate, and a slow-down and anti-smash device. The power box body is rectangular, with the door located on the front surface, the heat dissipation holes located on the sides of the power box body and forming an integrated structure, and the welding plate located on the rear surface of the power box body and welded to the slow-down and anti-smash device. The slow-down and anti-smash device allows the power box to be quickly moved upward along the utility pole during installation using rollers located within the clamp, preventing the pole from getting stuck. During disassembly, the weight of the power box is used to rotate the locking gear and engage it with the utility pole. The weight of the power box also pushes against the speed reduction bar, causing the power box to slow down and slide downward, preventing it from sliding rapidly and potentially hitting the ground or even hitting a worker, thereby protecting the power box and the worker.

[0004] The above-mentioned structure currently has a conical cement pole. When the clamp structure contacts the conical cement pole, the contact part between the clamp and the installed power box will be tilted, which may easily cause the power box to tilt at a small angle. The tilt of the power box may cause uneven force on the internal components, affecting its mechanical structure and electrical performance, such as offset of the electricity meter pointer, poor contact of the switch, etc., which in turn affects the measurement accuracy or causes malfunctions.

[0030] When smoke is not detected, the heat dissipation component 4 conducts electricity to the electricity meter 5 and the input wire 6 and performs ventilation. When smoke is detected, the heat dissipation component 4 cuts off the power to the electricity meter 5 and the input wire 6 and isolates the air to extinguish the fire, which is convenient for timely extinguishing of fire and avoiding causing greater damage, thereby improving safety. The heat dissipation component 4 has multiple functions; the pole connection component of the adjustable mounting component 3 is connected to the pole, the locking component is opened, the push-pull connection component pulls the box 1 to move, and the box 1 drives the rotating connection component to rotate. After the box 1 rotates to a vertical state, the locking component locks the rotating connection component, ensuring the stability of the box 1 and helping the box 1 to remain in a vertical state, thereby avoiding uneven force on the internal components of the electricity meter 5 due to the tilt of the box 1, and avoiding affecting the mechanical structure and electrical performance of the electricity meter 5.
