Technical Field

[0001] This application relates to the field of power measurement instrument technology, and in particular to electricity meters with dustproof function. Background Technology

[0002] As a core metering instrument for measuring electricity consumption, electricity meters are widely used in industrial and mining enterprises, buildings, infrastructure, and other places for electricity billing, energy management, and load monitoring. They are particularly prevalent in industrial environments, especially in workshops involved in metallurgy, cement manufacturing, ceramic firing, mining, and chemical processing.

[0003] Currently, when ordinary electricity meters are used in environments with high dust concentrations, the seams of the casing, the operation button area, the edge of the display panel, and the holes designed for ventilation and heat dissipation are the main channels for dust intrusion. Dust accumulates in the internal circuit board, electricity metering chip, surface, and gaps, which can lead to short circuits or creepage between components, causing malfunctions or even permanent damage. Non-conductive dust can easily form conductive bridges in humid environments, or cause partial discharge.

[0004] In other words, existing technologies have the following technical problems: ordinary electricity meters are prone to damage when used in environments with high dust concentrations. Therefore, an electricity meter with dustproof function is proposed to address the above problems. Summary of the Invention

[0035] Please see Figure 1-6 As shown, a dustproof energy meter includes:

[0036] The main body of the electricity meter 1 includes a rear housing 101, a front housing 102, a display panel 103, and a button area 104;

[0037] An energy meter chip 2 is installed inside the main body 1 of the energy meter, and a sealing layer 3 is fixedly provided on the outer surface of the energy meter chip 2;

[0038] A heat-conducting structure 4 is in contact with the energy meter chip 2, and one end of the heat-conducting structure 4 extends to the outside of the wall of the rear housing 101.

[0039] Evaporative cooling component 5, which is fixedly connected to the heat-conducting structure 4;

[0040] To address the issue that in existing technologies, when ordinary electricity meters are installed in dusty workshops, external dust can easily enter the meter and damage the internal electronic equipment, this application designs an electricity meter with a sealing protection function. By setting a sealing layer 3, the internal electronic equipment can be completely sealed and protected. At the same time, a heat-conducting structure 4 is set up, which can not only provide sealing protection, but also achieve good heat conduction and heat dissipation effects, thereby improving service life. It is particularly suitable for use in high-temperature and high-dust environments.

[0041] A sealing ring 106 is fixedly provided at the joint between the rear housing 101 and the front housing 102. Through this technical solution, the sealing ring 106 can effectively seal the joint.

[0042] Preferably, the sealing ring 106 is made of EPDM rubber or fluororubber, and the compression ratio is controlled at 15%-25% to ensure that the joint reaches the IP65 dustproof level.

[0043] The rear housing 101 and the front housing 102 are fixedly connected by mounting bolts 105.

[0044] A display panel 103 and a button area 104 are mounted on the outer surface of the front housing 102. Both the display panel 103 and the button area 104 are electrically connected to the energy meter chip 2. Preferably, a silicone diaphragm is mounted on the button area 104, and a glass panel is provided on the display panel 103, which is bonded to the display panel 103 by optical adhesive (OCA) or sealing adhesive, thereby achieving a sealing function.

[0045] The sealing layer 3 is made by potting epoxy resin or polyurethane potting compound to seal and cure the electricity meter chip 2, as well as the entire circuit board and internal components, forming an integrated waterproof and dustproof barrier.

[0046] The heat-conducting structure 4 includes a heat-conducting plate 401, a silicone grease heat-conducting layer 402, and heat-conducting fins 403. The heat-conducting plate 401 is fixedly disposed in the inner cavity of the main body 1 of the electricity meter. The heat-conducting plate 401 is in contact with the electricity meter chip 2. The joint between the heat-conducting plate 401 and the electricity meter chip 2 is filled with the silicone grease heat-conducting layer 402.

[0047] A plurality of heat-conducting fins 403 are fixedly connected to the outer surface of the heat-conducting plate 401. The heat-conducting fins 403 penetrate the rear housing 101 and extend to the outside of the wall of the rear housing 101. The joint between the heat-conducting fins 403 and the rear housing 101 is filled with sealant. Through this technical solution, the contact between the heat-conducting plate 401 and the electricity meter chip 2 can achieve a good heat conduction effect, so that the heat generated by the electricity meter chip 2 can be dissipated in time. Furthermore, the arrangement of the heat-conducting fins 403 increases the heat dissipation area and improves the heat dissipation effect.

[0048] The evaporative cooling component 5 includes a fixing plate 501, a fixing seat 502, a sponge block 503, and a water storage tank 504. The fixing plate 501 is fixedly installed on the side wall of the rear housing 101. The fixing seat 502 is fixedly connected to the bottom surface of the fixing plate 501. The fixing seat 502 has a groove inside. The sponge block 503 is fixedly installed in the groove of the fixing seat 502. The sponge block 503 is in contact with the heat-conducting fins 403.

[0049] A water storage tank 504 is fixedly connected to the upper surface of the fixing plate 501. The inner cavity of the water storage tank 504 is filled with pure water 505. One end of a connecting pipe 506 is fixedly connected to the bottom wall of the inner cavity of the water storage tank 504. The other end of the connecting pipe 506 extends into the inner cavity of the fixing seat 502 and is fixedly connected to the fixing seat 502. A capillary rope 507 is fixedly installed in the inner cavity of the connecting pipe 506. One end of the capillary rope 507 is connected to the sponge block 503, and the other end of the capillary rope 507 extends into the interior of the pure water 505. Through this technical solution, the pure water 505 can be slowly drawn into the interior of the sponge block 503 by the capillary action of the capillary rope 507. Then, through the contact between the sponge block 503 and the heat-conducting fins 403, and the action of gravity, the water slowly flows onto the heat-conducting fins 403. Due to the high temperature of the heat-conducting fins 403, the water evaporates. Evaporation absorbs heat, further improving the heat dissipation effect.

[0050] Preferably, the portion of the heat-conducting fin 403 extending outside the rear housing is provided with a flow guide groove structure, with a groove depth of 0.3-0.8mm, so that water flow can form a uniform water film on the fin surface.

[0051] A heat dissipation structure 6 is also provided on the side wall of the rear housing 101. The heat dissipation structure 6 includes a mounting plate 601 and a heat dissipation fan 602. The mounting plate 601 is fixedly installed on the side wall of the rear housing 101, and the heat dissipation fan 602 is installed on the mounting plate 601. Through this technical solution, the heat dissipation fan 602 can blow air to dissipate heat from the heat-conducting fins 403, and with the evaporation of water film, the heat dissipation efficiency is significantly improved.

[0052] Furthermore, the top of the water storage tank 504 is equipped with an openable sealing cover 508, which has a silicone airtight valve, making it easy to fill with water and maintaining a negative pressure environment inside the tank to promote capillary action.

[0053] Preferably, the capillary 507 is made of superhydrophilic modified glass fiber bundles.

[0054] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.

[0055] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
