Description

Technical Field

[0001] This application relates to the technical field of electricity meters, and more particularly to an electricity meter with heat dissipation and moisture-proof properties. Background Technology

[0002] As a key device in the power system for measuring electrical energy consumption, electricity meters are widely used in industrial, commercial, and residential electricity consumption. With the development of smart grids, higher requirements are placed on the functionality, stability, and environmental adaptability of electricity meters. In particular, electricity meters operating outdoors or in humid environments are susceptible to moisture intrusion, which can cause short circuits, corrosion, and other problems, affecting metering accuracy and equipment lifespan. Therefore, electricity meters with good moisture-proof performance have become a key focus of industry development.

[0003] Meanwhile, in order to ensure the long-term stable operation of electricity meters, heat dissipation holes are usually set on their outer casing to enhance ventilation and heat dissipation capabilities. However, while improving heat dissipation efficiency, the heat dissipation holes also bring the problem of dust and impurities entering the equipment and blocking the heat dissipation channels, which in turn leads to excessive temperature rise, poor heat dissipation, and even affects the normal operation of the electricity meter.

[0004] Chinese patent publication number CN118604417B discloses a building electricity meter. By setting a cover plate, the display screen of the electricity meter body can be protected to prevent external dust and impurities from falling on the display screen. When the cover plate is moved upward to expose the display screen, the roller cleaning brush can clean the heat dissipation holes under the action of the transmission mechanism, removing the garbage and impurities on the heat dissipation holes and ensuring the heat dissipation effect of the electricity meter body. However, the above structure can only remove floating dust and particulate matter on the outer surface of the heat dissipation holes. It is difficult to effectively remove small foreign objects that have penetrated into the heat dissipation holes due to air flow during long-term use, which can easily cause blockage inside the heat dissipation holes, affect the ventilation and heat dissipation effect, and reduce the working stability of the electricity meter. Summary of the Invention

[0005] This application aims to at least partially address one of the technical problems in the related art.

[0006] Therefore, one objective of this application is to provide an energy meter with heat dissipation and moisture-proof performance. The cleaning tube is driven by an electric telescopic rod to push and clean foreign objects in the heat dissipation holes, and the tip of the cleaning tube guides the foreign objects to the periphery of the heat dissipation holes, thereby improving cleaning efficiency and ensuring unobstructed heat dissipation channels. At the same time, in humid environments, the cleaning tube can seal the heat dissipation holes, effectively isolating external moisture and significantly improving the moisture-proof performance and reliability of the energy meter.

[0007] To achieve the above objectives, the first aspect of this application provides an energy meter with heat dissipation and moisture-proof performance, comprising an energy meter body and a protective component, wherein the protective component includes a plurality of heat dissipation holes formed on the energy meter body; a plurality of electric telescopic rods are installed on the energy meter body; a reciprocating plate is fixedly installed at the output end of the electric telescopic rods; a plurality of cleaning tubes are provided on the reciprocating plate; a blower mechanism is provided on the reciprocating plate; and a rotating mechanism is provided inside the plurality of cleaning tubes.

[0008] In addition, the energy meter with heat dissipation and moisture-proof performance proposed in this application may also have the following additional technical features: In one embodiment of this application, the ends of the plurality of cleaning tubes near the heat dissipation holes are provided with pointed ends, and the cleaning tubes are slidably connected to the corresponding heat dissipation holes.

[0009] In one embodiment of this application, a plurality of cleaning tubes are located on one side of a plurality of heat dissipation holes, and the plurality of cleaning tubes correspond one-to-one with the plurality of heat dissipation holes, and the cleaning tubes do not contact the heat dissipation holes.

[0010] In one embodiment of this application, the blower mechanism includes a plurality of blow holes formed on the circular surface of one end of the corresponding cleaning tube; a limiting plate is installed on one end of the cleaning tube and on one side of the blow holes; a plurality of air storage cylinders are fixedly installed on the reciprocating plate; and a push spring is installed in each of the plurality of air storage cylinders.

[0011] In one embodiment of this application, after the plurality of air holes are moved out of the main body of the electricity meter, the limiting plate contacts the main body of the electricity meter, and the limiting plate restricts the movement distance of the air holes, wherein the air holes are opened at an angle.

[0012] In one embodiment of this application, the plurality of air storage cylinders are slidably connected to the corresponding cleaning pipes, and one end of the plurality of push springs is connected to one end of the corresponding cleaning pipe.

[0013] In one embodiment of this application, the rotating mechanism includes a sealing shell that rotates within the corresponding cleaning pipe; a branch pipe is installed on the sealing shell; a transmission pipe is installed on the sealing shell; and a transmission plate is installed on the air storage cylinder.

[0014] In one embodiment of this application, one end of each of the plurality of branch pipes is located on the circular surface of the sealing shell, and the branch pipes are interconnected with the transmission pipe.

[0015] In one embodiment of this application, the sealing shell is rotatably connected to the cleaning tube, and when the transmission tube coincides with or partially coincides with the blowing hole, the transmission tube and the corresponding blowing hole are in communication with each other.

[0016] In one embodiment of this application, the transmission tube is provided with a threaded groove, and the transmission tube is connected to the transmission plate through the threaded groove.

[0017] The beneficial effects of the energy meter with heat dissipation and moisture-proof performance according to the embodiments of this application are as follows: (1) The cleaning tube is driven to move by the electric telescopic rod, so that it pushes and cleans the foreign objects in the heat dissipation hole. At the same time, the tip of the cleaning tube guides the foreign objects to the surrounding area of ​​the heat dissipation hole, which effectively improves the cleaning effect of the heat dissipation hole and optimizes the heat dissipation performance of the main body of the electricity meter. In addition, in a humid environment, the cleaning tube can also seal the heat dissipation hole to isolate external moisture, further enhancing the moisture resistance and reliability of the main body of the electricity meter.

[0018] (2) The foreign objects in the heat dissipation hole are first pushed by the cleaning pipe and dispersed to the surrounding area of ​​the heat dissipation hole. Then, the airflow generated by the movement of the air storage cylinder blows away the foreign objects around the heat dissipation hole, thereby achieving thorough cleaning of the foreign objects and effectively avoiding secondary blockage caused by the accumulation of foreign objects after they are pushed to the surrounding area of ​​the heat dissipation hole, thus improving the overall cleaning effect and heat dissipation reliability.

[0019] (3) By controlling the air blowers to blow out air in sequence, the airflow intensity of a single air blower can be effectively increased under the same air pressure conditions, thereby enhancing the removal effect on foreign objects. At the same time, by using the method of air blowing out air in turn for each air blower, the foreign objects around each air blower can be thoroughly cleaned, further improving the overall cleaning efficiency and reliability.

[0023] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0024] The following description, in conjunction with the accompanying drawings, describes an energy meter with heat dissipation and moisture-proof properties according to an embodiment of this application.

[0025] like Figures 1-3 As shown in the figure, the energy meter with heat dissipation and moisture-proof performance according to the present application embodiment includes an energy meter body 10 and a protective component 20. The protective component 20 includes a plurality of heat dissipation holes 201 formed on the energy meter body 10; a plurality of electric telescopic rods 202 are installed on the energy meter body 10; a reciprocating plate 203 is fixedly installed at the output end of the electric telescopic rods 202; a plurality of cleaning tubes 204 are provided on the reciprocating plate 203; a blower mechanism 205 is provided on the reciprocating plate 203; and a rotating mechanism 206 is provided inside the plurality of cleaning tubes 204.

[0026] In one embodiment of this application, such as Figure 3 As shown, the cleaning tubes 204 are pointed at one end near the heat dissipation hole 201, and the cleaning tubes 204 are slidably connected to the corresponding heat dissipation holes 201.

[0027] It should be noted that the tip of the cleaning tube 204 can guide the foreign object to the surrounding area of ​​the cleaning tube 204 when cleaning the foreign object. This prevents the foreign object from remaining on one end of the cleaning tube 204 after the flat cleaning tube 204 pushes it, so that after the cleaning tube 204 is reset, some of the foreign object at one end of the cleaning tube 204 will still block the heat dissipation hole 201, affecting the cleaning effect of the cleaning tube 204 on the heat dissipation hole 201.

[0028] In one embodiment of this application, such as Figure 2As shown, the multiple cleaning tubes 204 are located on one side of the multiple heat dissipation holes 201, and the multiple cleaning tubes 204 correspond one-to-one with the multiple heat dissipation holes 201, and the cleaning tubes 204 do not contact the heat dissipation holes 201.

[0029] Specifically, in actual use, the heat dissipation hole 201 is easily blocked by foreign objects, which affects the heat dissipation performance of the main body 10 of the electricity meter.

[0030] After the heat dissipation hole 201 on the main body 10 of the electricity meter is blocked, the output end of the electric telescopic rod 202 is moved by the control switch. The movement of the output end of the electric telescopic rod 202 will drive the reciprocating plate 203 to move. The movement of the reciprocating plate 203 will drive the cleaning tube 204 to move, so that the cleaning tube 204 pushes the foreign objects in the heat dissipation hole 201, thereby cleaning the foreign objects in the heat dissipation hole 201. After that, the output end of the electric telescopic rod 202 is reset, so that the heat dissipation hole 201 can continuously dissipate heat from the main body 10 of the electricity meter. When there is humid weather, after the electric telescopic rod 202 drives the cleaning tube 204 into the heat dissipation hole 201, the cleaning tube 204 continuously blocks the heat dissipation hole 201 to prevent the humid air from affecting the main body 10 of the electricity meter.

[0031] The cleaning tube 204 is moved by the electric telescopic rod 202, which pushes and cleans the foreign objects in the heat dissipation hole 201. At the same time, the tip of the cleaning tube 204 guides the foreign objects to the periphery of the heat dissipation hole 201, effectively improving the cleaning effect of the heat dissipation hole 201 and optimizing the heat dissipation performance of the electricity meter body 10. In addition, in humid environments, the cleaning tube 204 can also seal the heat dissipation hole 201 to isolate external moisture, further enhancing the moisture resistance and reliability of the electricity meter body.

[0032] In one embodiment of this application, such as Figures 3-5 As shown, the blower mechanism 205 includes a plurality of blow holes 2051 formed on the circular surface of one end of the corresponding cleaning tube 204; a limit plate 2052 is installed on one end of the cleaning tube 204 and on one side of the blow holes 2051; a plurality of air cylinders 2053 are fixedly installed on the reciprocating plate 203; and a push spring 2054 is installed in each of the plurality of air cylinders 2053.

[0033] In one embodiment of this application, such as Figures 3-5 As shown, after the multiple air holes 2051 are moved out of the main body 10 of the electricity meter, the limiting plate 2052 contacts the main body 10 of the electricity meter, and the limiting plate 2052 restricts the movement distance of the air holes 2051. The air holes 2051 are opened at an angle.

[0034] It should be noted that the end of the cleaning pipe 204 near the air storage cylinder 2053 is designed to be open, and the center of the air storage cylinder 2053 is hollow while the rest is solid. This allows the air pressure to flow along the center of the cleaning pipe 204 when the cleaning pipe 204 squeezes the gas in the air storage cylinder 2053, and finally be discharged through the blow hole 2051.

[0035] In one embodiment of this application, such as Figure 4 As shown, the plurality of air storage cylinders 2053 are slidably connected to the corresponding cleaning pipes 204, and one end of the plurality of push springs 2054 is connected to one end of the corresponding cleaning pipe 204.

[0036] It should be noted that the push spring 2054 retracts when the cleaning tube 204 enters the air storage cylinder 2053, and the push spring 2054 drives the cleaning tube 204 to reset when the electric telescopic rod 202 drives the air storage cylinder 2053 to reset.

[0037] Specifically, when the cleaning tube 204 cleans the foreign objects in the heat dissipation hole 201, some of the foreign objects cannot fall off and will stick around the heat dissipation hole 201. During subsequent heat dissipation, some of the foreign objects will enter the heat dissipation hole 201, which will affect the heat dissipation performance of the main body 10 of the electricity meter.

[0038] When the output end of the electric telescopic rod 202 drives the cleaning pipe 204 to move and clean the foreign objects in the heat dissipation hole 201, the cleaning pipe 204 also drives the limiting plate 2052 to move, thereby causing the limiting plate 2052 to contact the main body 10 of the energy meter. The limiting plate 2052 limits the cleaning pipe 204, preventing it from moving further. At this time, the air blowing hole 2051 on the cleaning pipe 204 is outside the main body 10 of the energy meter. If the output end of the electric telescopic rod 202 continues to retract, it can drive the air storage cylinder 2053 to move continuously. Since the cleaning pipe 204 is restricted from moving, the continuous movement of the air storage cylinder 2053 will cause the cleaning pipe 204 to compress the gas in the air storage cylinder 2053, allowing the gas in the air storage cylinder 2053 to enter the cleaning pipe 204 and finally be discharged through the air blowing hole 2051. The air discharged from the air blowing hole 2051 can blow away foreign objects around the cleaning pipe 204, thereby achieving the purpose of cleaning foreign objects. At the same time, the output end of the electric telescopic rod 202 can be reciprocated to achieve multiple cleaning of foreign objects, improving the cleaning effect.

[0039] The cleaning pipe 204 first pushes the foreign objects in the heat dissipation hole 201 to disperse them around the heat dissipation hole 201. Then, the airflow generated by the movement of the air storage cylinder 2053 blows away the foreign objects around the heat dissipation hole 201, thereby achieving thorough cleaning of the foreign objects. This effectively avoids the problem of secondary blockage caused by the accumulation of foreign objects after they are pushed to the heat dissipation hole 201, and improves the overall unblocking effect and heat dissipation reliability.

[0040] In one embodiment of this application, such as Figure 6 and Figure 7 As shown, in one embodiment of this application, the rotating mechanism 206 includes a sealing shell 2061 that rotates within the corresponding cleaning pipe 204; a branch pipe 2062 is installed on the sealing shell 2061; a transmission pipe 2063 is installed on the sealing shell 2061; and a transmission plate 2064 is installed on the air storage cylinder 2053.

[0041] In one embodiment of this application, such as Figure 6 and Figure 7 As shown, one end of each of the multiple branch pipes 2062 is located on the circular surface of the sealing shell 2061, and the branch pipes 2062 are interconnected with the transmission pipe 2063.

[0042] In one embodiment of this application, such as Figure 6 and Figure 7 As shown, the sealing shell 2061 is rotatably connected to the cleaning pipe 204 in a sealed manner. When the transmission pipe 2063 overlaps or partially overlaps with the air blowing hole 2051, the transmission pipe 2063 and the corresponding air blowing hole 2051 are interconnected.

[0043] In one embodiment of this application, such as Figure 7 As shown, the transmission tube 2063 is provided with a threaded groove, and the transmission tube 2063 is connected to the transmission plate 2064 through the threaded groove.

[0044] It should be noted that both ends of the transmission pipe 2063 are designed to be open. One end is connected to the branch pipe 2062, and the other end is used for air intake, so that the air in the air storage cylinder 2053 can enter the transmission pipe 2063 and then enter the branch pipe 2062 through the transmission pipe 2063.

[0045] Specifically, in the actual process of cleaning foreign objects, the air pressure generated by the air compression inside the air storage cylinder 2053 by the cleaning pipe 204 is limited. When the limited air pressure flows out from multiple air holes 2051 at the same time, the flow of gas will be reduced, which will result in limited cleaning force for foreign objects.

[0046] When the electric telescopic rod 202 moves the air tank 2053, the air tank 2053 also moves, which in turn moves the transmission plate 2064. Since the transmission plate 2064 is threadedly connected to the transmission pipe 2063, the movement of the transmission plate 2064 causes the transmission pipe 2063 to rotate. The rotation of the transmission pipe 2063 causes the sealing shell 2061 to rotate. When one end of the transmission pipe 2063 on the sealing shell 2061 rotates and overlaps or partially overlaps with one of the branch pipes 2062, then the transmission pipe 2063... 63 is then connected to the branch pipe 2062. At this time, the gas generated by the cleaning pipe 204 squeezing the air storage cylinder 2053 can flow through the transmission pipe 2063 to the corresponding branch pipe 2062, and then through the branch pipe 2062 to the corresponding air blowing hole 2051. Finally, the airflow discharged from the air blowing hole 2051 cleans the foreign objects in the corresponding area. At the same time, the sealing shell 2061 and the transmission pipe 2063 will continue to rotate, and airflow can be discharged from different air blowing holes 2051 in sequence to clean the foreign objects around the air blowing hole 2051.

[0047] By controlling the air blowers 2051 to blow air out individually in sequence, the airflow intensity of a single air blower 2051 is effectively increased under the same air pressure conditions, and the concentrated airflow is used to enhance the local cleaning intensity. At the same time, by using the method of exhausting air from each air blower 2051 in turn, the foreign objects around each air blower 2051 are thoroughly cleaned, further improving the overall cleaning efficiency and reliability.

[0048] In summary, the energy meter with heat dissipation and moisture-proof performance of this application embodiment uses the electric telescopic rod 202 to drive the cleaning tube 204 to move, so as to push and clean the foreign objects in the heat dissipation hole 201. At the same time, the tip of the cleaning tube 204 guides the foreign objects to the periphery of the heat dissipation hole 201, effectively improving the cleaning effect of the heat dissipation hole 201 and optimizing the heat dissipation performance of the energy meter body 10. In addition, in humid environments, the cleaning tube 204 can also seal the heat dissipation hole 201 to isolate external moisture, further enhancing the moisture-proof capability and reliability of the energy meter body 10.
