Description

Technical Field

[0001] The present application relates to the technical field of meter boxes, and in particular to an electric energy meter box. Background Art

[0002] As an indispensable device in the power system, the importance of the energy meter box has become increasingly prominent with the booming power industry and the increasing demand for energy management. It not only plays a key role in the field of residential electricity consumption, but is also widely used in many fields such as industry and commerce, becoming an important tool for achieving effective power management and energy conservation.

[0003] However, in a design of an electric energy meter box in the related art, although its structure includes a box body and a box door, and multiple installation cavities are separated inside the box body to accommodate electric energy meters, incoming line switches, outgoing line switches, circuit breakers and other electrical equipment, there is a significant problem when installing these equipment: the electrical equipment is usually directly fixed to the inner wall of the box body with screws. Although this approach is simple and direct, it leads to unreasonable space planning inside the box body, which in turn affects the ventilation and heat dissipation effect inside the box body.

[0004] Specifically, because the electrical equipment is installed directly against the inner wall of the box, the air circulation inside the box is poor, and the heat generated by the electrical equipment is difficult to dissipate effectively, thus failing to meet the heat dissipation performance requirements of the electrical equipment. In the long run, this adverse thermal environment will be detrimental to the normal operation of the internal electrical equipment, and may even cause equipment failure or damage, bringing potential risks to the stable operation of the power system, and there is room for improvement. Summary of the invention

[0005] The purpose of this application is to provide an electric energy metering box to solve the problem that the installation method of electrical equipment in the above-mentioned related technology is unreasonable, which affects the heat dissipation performance inside the box and poses a safety hazard.

[0006] The electric energy meter box provided in this application adopts the following technical solution: An electric energy meter box comprises a box body and a box door hinged to the box body by a hinge shaft, wherein a plurality of heat dissipation openings are provided on the side of the box body; a plurality of support plates are fixedly provided on the inner wall of the box body, and a mounting plate for installing related electrical equipment is commonly fixedly provided on the ends of the plurality of support plates away from the box body, and a flow gap is preset between the mounting plate and the inner wall of the box body.

[0007] By adopting the above technical solution, due to the coordinated setting of the circulation gap and the heat dissipation port, during the application of the electric energy meter box, the air inside the box can have sufficient circulation space through the setting of the circulation gap, and can timely exchange the internal and external gases through the heat dissipation port, thereby ensuring the heat dissipation performance of the electric energy meter box and reducing the safety hazards caused by insufficient heat dissipation.

[0008] Optionally, a pull ring is fixedly provided on the box door, and an observation window is provided on the box door.

[0009] By adopting the above technical solution, it is convenient for the user to control the opening and closing of the box door through the pull ring, and it is also convenient for the user to directly observe the electrical equipment installed inside the box through the observation window, thereby reducing the difficulty for the user to observe the status of the electrical equipment.

[0013] Optionally, a guide rod is fixedly provided on the side surface of the lower limit plate, and a guide groove for inserting the guide rod is provided on the inner wall of the box body.

[0014] By adopting the above technical solution, due to the coordinated arrangement of the guide rod and the guide slot, when the lower limit plate slides back and forth, the guide rod slides synchronously in the guide slot, thereby improving the stability of the lower limit plate during the sliding process.

[0015] Optionally, the guide slot is a through slot, and the end of the guide rod extends through the guide slot to the outside of the box body. The outside of the box body is provided with a blocking plate for blocking the heat dissipation port, and the outer end of the guide rod is fixedly connected to the blocking plate; a blocking through hole corresponding to the heat dissipation port is provided on the blocking plate, and the blocking plate can slide synchronously with the lower limit plate, and the blocking through hole coincides with the heat dissipation port when the electrical equipment is installed between the upper limit plate and the lower limit plate.

[0016] By adopting the above technical solution, due to the setting of the blocking plate, when the electrical equipment is installed between the upper limit plate and the lower limit plate, the blocking through hole on the blocking plate coincides with the heat dissipation port, so that the box in this state can perform normal heat dissipation; when the electrical equipment is removed, the blocking through hole and the heat dissipation port are staggered, that is, the heat dissipation port is in a blocked state, thereby protecting the box in this state; when the electrical equipment in the box is installed normally, its heat dissipation performance is guaranteed, and when it is not installed, the heat dissipation port on the box is blocked to prevent external impurities from entering the inside of the box in this state through the heat dissipation port.

[0022] By adopting the above technical solution, since the side edge of the box door close to the hinge axis is flush with the side edge of the box door with the heat dissipation port, when the blocking plate is rotated close to the side of the box body and fixed to a state of abutting the side of the box door close to the hinge axis, the elastic clip is inserted into the corresponding positioning groove, and the blocking plate locks the box door. At this time, the box door cannot be opened normally and is in a further locked state, reducing the possibility of the box door being opened by irrelevant blockage; when the blocking plate is in a normal state of blocking the heat dissipation port, the elastic clip can slide in the guide slot along the length direction of the guide slot, that is, the elastic clip can play a role of guiding and limiting, and the box door can be opened normally at this time.

[0023] Optionally, an electromagnetic lock is fixedly provided on the blocking plate, and a locking groove for inserting and sliding a lock tongue of the electromagnetic lock is provided on the box body, and the locking groove is parallel to the length direction of the guide groove.

[0024] By adopting the above technical solution, when the elastic clip is inserted into the positioning groove, the lock tongue of the electromagnetic lock can be inserted into the corresponding locking slot, which can better lock the blocking plate in this state and reduce the possibility of unauthorized persons rotating the blocking plate in this state.

When the blocking plate is rotated close to the side of the box body and fixed to abut the side of the box door close to the hinge axis, the elastic clip is inserted into the corresponding positioning groove, and the blocking plate locks the box door. At this time, the box door cannot be opened normally and is in a further locked state, reducing the possibility of opening the box door due to irrelevant blockage.
