Description

Technical Field

[0001] This utility model relates to the field of power metering equipment technology, specifically to a power metering device with a dip-coating structure. Background Technology

[0002] Electricity metering devices occupy a crucial position in the power system, and their accuracy directly affects the economic accounting and fair trading of electricity production, supply, and consumption. From early bulky electricity meters based on electrolysis principles to today's electronic electricity meters that integrate electronic technology, possess high precision, and offer multiple functions, electricity metering devices have continuously innovated and upgraded. With the construction of new power systems and the large-scale integration of new energy sources, microgrids, and IoT devices, higher demands are placed on electricity metering devices. They must not only accurately measure electricity but also operate stably in complex environments to meet the diversified needs of energy services.

[0003] In practical applications, existing electricity metering devices suffer from numerous problems. On one hand, heat dissipation is a significant challenge. The meter continuously generates heat during operation; if this heat cannot be dissipated effectively and promptly, it can lead to excessively high internal temperatures, causing performance degradation of electronic components, metering errors, and even shortening the device's lifespan. For example, some traditional electricity metering devices rely solely on natural heat dissipation, resulting in low efficiency. Under high load conditions, the device temperature rises sharply, severely impacting metering accuracy. On the other hand, dust protection is inadequate. Dust and other impurities can easily enter the device through gaps and openings, adhering to the surfaces of electronic components. Accumulation to a certain extent can affect heat dissipation and may even cause short circuits, increasing maintenance costs and the risk of failure. Therefore, we propose an electricity metering system with a dip-coated structure. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an energy meter with a dip-coating structure.

[0005] The technical solution of this utility model is:

[0006] An electricity metering device with a dip-coated structure includes a meter body and a housing mounted on the outside of the meter body. A heat dissipation assembly is installed at the bottom of the housing, and several equally spaced L-shaped heat dissipation fins are installed on the top of the heat dissipation assembly. The L-shaped heat dissipation fins are in close contact with the outer wall of the meter body. An opening communicating with the heat dissipation assembly is provided at the bottom of the housing. An air inlet is provided on one side wall of the housing, and a dustproof screen is installed on the air inlet. Several wiring holes are provided on the top of the housing, and a sealing gasket is installed in each wiring hole. The heat dissipation assembly includes a mounting frame fixed to the bottom of the housing. The mounting frame is internally divided into several mounting compartments by several partitions, and a blower assembly is installed in each mounting compartment. The heat dissipation assembly has multiple equally spaced L-shaped heat dissipation fins on its top, which are in close contact with the outer wall of the meter body, enabling efficient heat conduction from the meter body. The opening at the bottom of the housing communicates with the heat dissipation assembly for heat dissipation. An air inlet is located on one side wall of the casing, and a dust filter is installed at the air inlet to prevent dust and other impurities from entering.

[0007] Specifically, the air-blowing assembly includes a horizontal plate fixed to the inner wall of the mounting chamber, on which a cooling motor is mounted. The output shaft of the cooling motor is coaxially fixed to a fan blade. The air-blowing assembly further optimizes the heat dissipation effect by including the horizontal plate fixed to the inner wall of the mounting chamber, the cooling motor mounted on the horizontal plate, and the fan blade coaxially fixed to the output shaft of the cooling motor. By driving the fan blade to rotate through the cooling motor, airflow can be accelerated, enhancing heat dissipation efficiency.

[0008] It should also be noted that the bottom of the outer casing is open and a frame is fixedly installed thereon, and a bottom filter screen is installed at the bottom of the frame. This further enhances the dustproof capability of the device.

[0009] It should be added that when the cooling motor is working, the fan blades draw air from the air inlet into the housing and out from the bottom of the mounting bracket.

[0010] Preferably, a rear side plate is fixedly installed on the rear outer wall of the housing, and the rear side plate has several fixing holes. The fixing holes on the rear side plate facilitate the installation and fixing of the device.

[0011] Specifically, a door is hinged to the front of the outer casing, with an observation window and a handle attached to the door. This facilitates observation of the internal components and operation of the device.

[0012] It should be noted that a mounting plate is bolted to the bottom of the mounting bracket, and a coarse filter screen is fixedly installed inside the mounting plate. This multi-layered filtration structure effectively blocks dust and extends the service life of the device.

[0013] It should be added that the observation window occupies two-thirds of the door opening area, and the observation window is made of colorless and transparent glass to ensure good visibility.

[0014] Compared with existing technologies, the advantages of this invention are as follows: This invention uses L-shaped heat dissipation fins combined with a heat dissipation assembly to quickly remove the heat generated by the metering instrument during operation, avoiding measurement errors and equipment failures caused by high temperatures, ensuring stable operation, and extending the equipment's service life. The device is equipped with multiple dustproof nets to effectively block dust, reduce the probability of equipment failure, and reduce maintenance costs. Furthermore, the door is equipped with an observation window and handle for convenient operation and inspection; the rear panel fixing holes facilitate installation; and the sealing gasket in the wiring hole ensures airtightness, guaranteeing accurate measurement and overall practicality.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] Please see Figures 1-4 This utility model provides a technical solution:

[0022] An electrical energy meter with a dip-coated structure includes a meter body 4 and a housing 1 installed outside the meter body 4. A heat dissipation component 2 is installed at the bottom of the housing 1, and a number of L-shaped heat dissipation fins 6 are installed at the top of the heat dissipation component 2. The L-shaped heat dissipation fins 6 are in close contact with the outer wall of the meter body 4. An opening communicating with the heat dissipation component 2 is provided at the bottom of the housing 1. An air inlet is provided on one side wall of the housing 1, and a dustproof net 10 is provided on the air inlet. A number of wire holes are provided at the top of the housing 1, and a sealing gasket 15 is installed in each wire hole. The heat dissipation component 2 includes a mounting bracket 20 fixed to the bottom of the housing 1. The mounting bracket 20 is divided into a number of mounting chambers 22 by a number of partitions 23, and a blower component is installed in each mounting chamber 22. The outer casing 1, mounted on the outside of the measuring instrument body 4, cooperates with the bottom heat dissipation component 2. L-shaped heat dissipation fins are tightly fitted to the outer wall of the measuring instrument body 4, efficiently conducting heat. The heat is dissipated through the bottom opening of the outer casing 1 and the heat dissipation component 2, solving the heat dissipation problem during instrument operation, ensuring stable equipment operation, and preventing measurement errors and malfunctions due to overheating. A dust filter 10 is installed at the air inlet on the side wall of the outer casing 1 to prevent dust and impurities from entering, maintaining internal cleanliness and improving equipment reliability. The sealing gasket 15 at the top wiring hole ensures airtightness, reduces external interference, and guarantees measurement accuracy. The air blowing component within the mounting bracket 20 of the heat dissipation component 2 further enhances heat dissipation through airflow, increasing the device's heat dissipation capacity and ensuring the measuring instrument is always at a suitable operating temperature.

[0023] In a preferred embodiment, the blower assembly includes a horizontal plate 24 fixed to the inner wall of the mounting chamber 22. A cooling motor 25 is mounted on the horizontal plate 24, and a fan blade 26 is coaxially fixed to the output shaft of the cooling motor 25. In this blower assembly, the horizontal plate 24 fixes the cooling motor 25, and the motor output shaft coaxially fixes the fan blade 26. This structure allows the fan blade 26, driven by the cooling motor 25, to form a targeted airflow, greatly improving heat dissipation efficiency and accurately and quickly removing heat from the area surrounding the meter.

[0024] In a preferred embodiment, the bottom of the outer casing 1 is open and an outer frame 50 is fixedly installed thereon, and a bottom filter 5 is installed at the bottom of the outer frame 50. The outer frame 50 is fixed at the bottom opening of the outer casing 1 and the bottom filter 5 is installed thereon. Together with the dustproof screen 10 at the air inlet, a double dustproof barrier is formed, which further reduces the risk of dust entering the device, extends the service life of the equipment, and reduces maintenance work caused by dust accumulation.

[0025] In a preferred embodiment, when the cooling motor 25 is operating, the fan blades 26 draw air from the air inlet into the housing 1 and outward from the bottom of the mounting bracket 20. The fan blades 26 drawing air in from the air inlet and outward from the bottom of the mounting bracket 20 clearly define the air circulation path, ensuring a continuous and effective cooling airflow inside the device and maintaining a stable cooling effect.

[0026] As a preferred embodiment, a rear side plate 3 is fixedly installed on the rear outer wall of the outer casing 1, and the rear side plate 3 has a plurality of fixing holes 30. The fixing holes 30 on the rear side plate 3 fixed to the rear outer wall of the outer casing 1 facilitate the stable installation of the device in different positions, enhance the convenience and stability of the device installation, and adapt to the needs of diverse installation scenarios.

[0027] In a preferred embodiment, a door 11 is hinged to the front of the outer casing 1 via a hinge 13. An observation window 12 and a handle 14 are installed on the door 11. The door 11, with its observation window 12 and handle 14, allows staff to easily view and operate the device's interior, improving its ease of use and visibility.

[0028] In a preferred embodiment, a mounting plate 21 is fixedly mounted to the bottom of the mounting bracket 20 by bolts, and a coarse filter 27 is fixedly mounted inside the mounting plate 21. The mounting plate 21, which is fixed to the bottom of the mounting bracket 20 by bolts, and the coarse filter 27, together with the air inlet dustproof net 10 and the bottom filter 5, constitute a multi-layer filtration system, which blocks dust in all directions, creates a cleaner operating environment for the meter, and improves the stability and reliability of the equipment.

[0029] As a preferred embodiment, the observation window 12 occupies two-thirds of the area of ​​the door 11, and the observation window 12 is made of colorless and transparent glass. The fact that the observation window 12 occupies two-thirds of the area of ​​the door 11 and is made of colorless and transparent glass ensures that staff have a wide and clear field of vision, facilitating timely and accurate monitoring of the internal operating status of the device, and aiding in equipment maintenance and management.

[0030] In a practical application scenario, suppose we install this energy metering device with a dip-coated structure in an industrial plant to monitor power consumption. First, align the fixing holes 30 on the rear panel 3 with the pre-set installation points on the plant wall, and use bolts to fix the device to the wall. At this point, the position of the device is determined, and the rear panel 3 provides stable support and a mounting base.

[0031] Next, open the front door 11 and place the measuring instrument body 4 inside the outer casing 1, ensuring that the L-shaped heat dissipation fins 6 are in close contact with the outer wall of the measuring instrument body 4 to achieve good heat conduction. Close the door 11 by operating the handle 14 on the door 11 to ensure that the door is tightly closed. At this time, the observation window 12 allows the operator to clearly observe the working status of the measuring instrument body 4 inside the device. Since the observation window 12 occupies two-thirds of the area of ​​the door 11 and is made of colorless transparent glass, it has a wide field of view and high clarity.

[0032] During operation, air from the plant enters through the air inlet on the side wall of the outer casing 1. The dust filter 10 at the inlet removes most of the dust and other impurities. The cooling motor 25 in the heat dissipation assembly 2 starts working, driving the fan blades 26 to rotate. The fan blades 26 draw the air entering the outer casing 1 into the casing 1 through the air inlet, passing around the meter body 4 and carrying away the heat it generates. Then, the hot air is drawn out from the bottom of the mounting bracket 20. During this process, the coarse filter 27 in the mounting plate 21 at the bottom of the mounting bracket 20 and the bottom filter 5 at the bottom of the outer frame 50 further filter the exhaust air to prevent dust from re-entering the device. Through multiple filtration and heat dissipation measures, the meter body 4 is ensured to operate stably in a clean and well-ventilated environment, effectively improving the accuracy of electricity metering and extending the device's service life.

[0033] When using the energy meter with the dip-coated structure of this utility model:

[0034] Heat dissipation principle

[0035] During operation, the measuring instrument body 4 generates heat. L-shaped heat dissipation fins are tightly fitted to its outer wall, utilizing the excellent thermal conductivity of metal to quickly conduct heat from the measuring instrument body 4 to the heat dissipation fins. The heat dissipation motor 25 in the heat dissipation assembly 2 drives the fan blades 26 to rotate, creating airflow inside the outer casing 1. Air from the factory enters through the air inlet on the side wall of the outer casing 1, where a dust filter 10 blocks dust and impurities. The incoming cool air, driven by the fan blades 26, flows through the measuring instrument body 4, absorbing the heat it emits and becoming hot air. The hot air then flows from the opening at the bottom of the outer casing 1, which connects to the heat dissipation assembly 2, to the bottom of the mounting bracket 20, and is then drawn out of the outer casing 1, thus achieving continuous heat dissipation through this cycle.

[0036] Dustproof principle

[0037] To prevent dust and other impurities from affecting the performance and lifespan of the electricity metering device, the device is equipped with multiple dustproof structures. A dust filter 10 is installed at the air inlet on the side wall of the outer casing 1 to initially filter the incoming air. A bottom filter 5 at the bottom of the outer frame 50 further blocks dust entering from the bottom. A coarse filter 27 inside the bottom mounting plate 21 of the mounting bracket 20 prevents dust from re-entering when hot air is exhausted. These dust filters 10 work together to create a relatively clean internal environment, ensuring the normal operation of the metering instrument body 4.

[0038] Overall work collaboration

[0039] Throughout the entire electricity metering process, electrical energy is connected to the meter body 4 through the wiring hole. The sealing gasket 15 inside the wiring hole ensures a tight seal and prevents external interference. The meter body 4 generates heat during operation, which is dissipated through the heat dissipation component 2 to maintain a suitable operating temperature. Personnel can observe the internal condition of the device at any time through the observation window 12 on the door 11 and conveniently open and close the door using the handle 14. The fixing holes 30 on the rear panel 3 ensure that the device is securely installed on factory walls or other locations. The combined effect of these multiple structures enables the electricity metering device with its dip-coated structure to accurately and stably complete the electricity metering task.
