Abstract
Description
Technical Field
[0001] This utility model relates to the field of electricity meter technology, specifically a fireproof and heat-insulating electricity meter. Background Technology
[0002] In power systems, electricity meters are key devices for measuring electricity consumption, and their stable and reliable operation is crucial. However, in actual use, electricity meters face many factors that affect their performance and lifespan.
[0003] Existing equipment has the following drawbacks: Electricity meters generate heat during operation. With the continuous growth of electricity demand and the increasing complexity of smart meter functions, the integration of their internal electronic components is becoming increasingly sophisticated, significantly increasing the heat generated during operation. If this heat cannot be dissipated effectively and promptly, excessively high temperatures will accelerate the aging of electronic components, leading to decreased measurement accuracy, and even causing component combustion and fires, shortening their lifespan and affecting the accuracy and reliability of electricity metering.
[0004] Therefore, this application proposes a fireproof and heat-insulating energy meter to solve the above-mentioned problems. Utility Model Content
[0005] The purpose of this invention is to provide a fireproof and heat-insulating energy meter to solve the problem that excessively high temperatures accelerate the aging of electronic components, leading to a decrease in the measurement accuracy of the energy meter.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fireproof and heat-insulating energy meter, including a fixing base disposed on one side of the energy meter for fixing the energy meter to the equipment, and further comprising: A heat dissipation unit is disposed between the mounting base and the energy meter to dissipate heat from the energy meter; An air-cooling unit is disposed inside the heat dissipation unit and is used to provide air cooling for the electricity meter.
[0007] The heat dissipation unit includes: The outer cover has a square frame design and is fixed to the side of the electricity meter near the mounting base; The inner cover is fixed to the fixed base and movably fitted inside the outer cover; The inner cover has ventilation openings.
[0008] A power component for pushing the outer cover off the inner cover is provided between the outer cover and the inner cover.
[0009] The inner cover has a protective shell on the side away from the electricity meter for sealing and protecting the electricity meter.
[0010] The protective shell is equipped with a protective net.
[0011] The air-cooling unit includes: A cover is installed on the protective netting; A fan, located inside the mounting cover, is used to provide air cooling for the energy meter when the outer cover is pushed out from the inner cover.
[0012] Compared with the prior art, the beneficial effects of this utility model are: The combination of a heat dissipation unit and a cooling unit in this invention achieves dual heat dissipation for the electricity meter. During daily use, the ventilation equipment on the heat dissipation unit is turned on, creating an airflow channel that can initially dissipate the heat generated by the electricity meter. When the internal temperature of the electricity meter exceeds a set value, and ventilation alone is insufficient to effectively dissipate the heat, the cooling unit is activated to accelerate the airflow inside the electricity meter, enhancing the cooling effect and effectively reducing the operating temperature of the electricity meter. This ensures that the internal electronic components operate in a suitable temperature environment, improving the measurement accuracy and service life of the electricity meter.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-7 This utility model provides a technical solution: a fireproof and heat-insulating energy meter, including a fixing base 3 disposed on one side of the energy meter 1 for fixing the energy meter 1 to the equipment, and further including: a heat dissipation unit 2 disposed between the fixing base 3 and the energy meter 1 for dissipating heat from the energy meter 1; and an air-cooling unit 4 disposed inside the heat dissipation unit 2 for air-cooling the energy meter 1.
[0017] It should be noted that during operation, when installing the electricity meter 1, the mounting base 3 is first fixed to the equipment to be installed (such as a wall or a mounting bracket for power distribution equipment), and then the electricity meter 1 is fixed on the mounting base 3, completing the assembly of the electricity meter 1. A temperature sensor is installed inside the electricity meter 1, and the temperature sensor is electrically connected to the power unit on the heat dissipation unit 2 via a PLC control element. When the temperature sensor detects that the internal temperature of the electricity meter 1 exceeds a set value, it will open the heat dissipation unit 2, opening the rear side of the electricity meter 1 to dissipate heat. Then, it controls the air cooling unit 4 to open, allowing the air cooling unit 4 to dissipate heat from the electricity meter 1. The combination of heat dissipation unit 2 and air-cooling unit 4 enables dual heat dissipation for the electricity meter 1. During daily use, the ventilation equipment on heat dissipation unit 2 is turned on, forming a certain air circulation channel, which can initially dissipate the heat generated by the electricity meter 1. When the internal temperature of the electricity meter 1 exceeds the set value, and ventilation cannot effectively dissipate the heat in the electricity meter 1, air-cooling unit 4 is turned on to accelerate the air flow inside the electricity meter 1, enhance the air-cooling effect of the electricity meter 1, effectively reduce the operating temperature of the electricity meter 1, ensure that its internal electronic components work in a suitable temperature environment, reduce the occurrence of fires, and improve the measurement accuracy and service life of the electricity meter 1.
[0018] In one embodiment, the heat dissipation unit 2 includes: an outer cover 21, which is square-shaped and fixed to the side of the energy meter 1 near the mounting base 3; an inner cover 22, which is fixed to the mounting base 3 and movably fitted inside the outer cover 21; and a ventilation opening 2201 is provided on the inner cover 22.
[0019] This design is for reference. Figure 4 ,as well as Figure 6-7The inner wall of the inner cover 22 abuts against the inner wall of the outer cover 21, which allows for a stable connection between the inner cover 22 and the outer cover 21. The ventilation opening 2201 on the inner cover 22 works ingeniously with the sleeve structure of the outer cover 21 and the inner cover 22 to push the outer cover 21 away from the outside of the inner cover 22, so that the ventilation opening 2201 is opened. External cold air can enter the cavity between the inner cover 22 and the outer cover 21 through the ventilation opening 2201, and absorb heat by contacting the surface of the inner cover 22. Then the hot air rises and is discharged from the top of the outer cover 21 or other openings, forming a continuous convection circulation, which effectively accelerates the dissipation of heat. Compared with the traditional closed or simple ventilation structure, it improves the heat dissipation efficiency and can carry away the heat generated by the power meter 1 more quickly, reducing its operating temperature.
[0020] In one embodiment, a power member 24 for pushing the outer cover 21 off the inner cover 22 is provided between the outer cover 21 and the inner cover 22.
[0021] This design is for reference. Figure 3 , Figure 6 ,as well as Figure 7 The power component 24 includes, but is not limited to, an electric telescopic rod. When the power component 24 pushes the outer cover 21 off the inner cover 22, the vent 2201 on the inner cover 22 opens, which allows the airflow generated by the air-cooling unit 4 to flow more smoothly in the gap, forming a stronger airflow circulation. The airflow can exchange heat more fully with the surface of the inner cover 22 and the heat emitted by the energy meter 1, thereby accelerating the heat dissipation and effectively reducing the operating temperature of the energy meter 1.
[0022] In one embodiment, a protective shell 23 for sealing and protecting the electricity meter 1 is provided on the side of the inner cover 22 away from the electricity meter 1.
[0023] This design is for reference. Figure 4-6 The protective shell 23 isolates the inner cover 22 from the external environment, forming a tight barrier that effectively prevents dust, particulate matter and other impurities from entering the inside of the electricity meter 1, thereby improving the service life of the electricity meter 1.
[0024] In one embodiment, a protective net 25 is provided on the protective shell 23.
[0025] This design is for reference. Figure 3-6 The protective net 25 can filter dust particles in the air. While blocking foreign objects, the protective net 25 will not obstruct the normal flow of air. It can ensure the effective exchange of air inside and outside the protective shell 23, which is conducive to the timely dissipation of heat generated by the power meter 1 during operation.
[0026] In one embodiment, the air-cooling unit 4 includes: a mounting cover 41 disposed on the protective net 25; and a fan 42 disposed inside the mounting cover 41 for air-cooling the energy meter 1 when the outer cover 21 is pushed out from the inner cover 22.
[0027] This design is for reference. Figure 2-3 ,as well as Figure 6 When the outer cover 21 is pushed out from the inner cover 22, the fan 42 starts and can form a directional airflow. The mounting cover 41 is set on the protective net 25 and can guide the airflow directly to the key heat-generating parts of the electricity meter 1, which can effectively remove heat, improve heat dissipation efficiency, and reduce the temperature of the electricity meter 1 in a short time, keeping it within a suitable operating temperature range.
