They are the basic equipment for electricity settlement and supply and demand management in the power grid. Their development is accompanied by the upgrading of the power industry and metering technology. The core function of existing smart meters is to accurately measure electricity consumption.

[0003] Existing smart meters consist of a casing, wiring terminals, and a core control module. When the meter is in use, external dust may adhere to the wiring terminals. Dust falls into the wiring terminals and adheres to the surface of the terminals, causing increased contact resistance and resulting in heat generation in the wiring terminals. Prolonged heating will accelerate the oxidation of the terminals, further aggravating poor contact. In severe cases, it may cause sparking, tripping, and other phenomena, posing a potential electrical safety hazard.

[0004] Therefore, we have made improvements to this and proposed a protective smart energy meter. Summary of the Invention

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0019] As described in the background section, dust easily accumulates on the terminals of smart meters, which can cause the terminals to overheat and pose a safety hazard.

[0020] To address this technical problem, the present invention provides a protective smart energy meter, which is applied to energy meters.

[0021] For details, please refer to Figure 1 - Figure 7 As shown, the protective smart energy meter specifically includes: a mounting base 1, an energy meter 101 mounted on the mounting base 1, and a protective mechanism 2 mounted on the mounting base 1; The protective mechanism 2 includes a rotating ring 201 mounted on the mounting base 1, a semi-circular disk 202 mounted on the rotating ring 201, a sliding groove 203 mounted on the semi-circular disk 202, a sliding column 204 slidably mounted on the sliding groove 203, a mounting bracket 205 mounted on the sliding column 204, a filter screen 206 mounted on the mounting bracket 205, a limiting groove 207 mounted on the mounting bracket 205, a fixing column 208 mounted on the rotating ring 201, and a limiting block 209 rotatably mounted on the fixing column 208.

[0022] The protective smart energy meter provided by this invention addresses the problem in the prior art where dust easily accumulates on the wiring terminals of smart energy meters, causing the terminals to overheat and posing safety hazards. This application utilizes a protective mechanism 2, which drives the mounting bracket 205 and filter 206 to unfold and wrap around the meter 101. This prevents external dust from contacting the wiring terminals of the meter 101, thus avoiding the safety hazards caused by dust accumulation on the wiring terminals and improving the safety of the device. By using the protective mechanism 2, the mounting bracket 205 and filter screen 206 are driven to unfold and be fixed on the mounting base 1. The frame formed by the mounting bracket 205 and filter screen 206 protects the meter 101, reduces the damage caused by external impacts to the meter 101, protects the meter 101, and improves the service life of the meter 101. This solves the problem that the meter 101 is easily damaged by external impacts in the prior art. By using the protective mechanism 2, filtered air is driven to cool the inside of the meter 101, reducing the internal temperature of the meter 101. This reduces the risk of components aging due to excessive internal temperature, improves the service life of the meter 101, and solves the problem of internal component damage caused by excessive internal temperature in the existing technology.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a protective smart energy meter has a limiting block 209 slidably disposed on a limiting groove 207, and a torsion spring 210 disposed on the outside of a fixing post 208. The two ends of the torsion spring 210 are respectively connected to the corresponding surfaces of the limiting block 209 and the rotating ring 201. When using, such as Figure 2 As shown, multiple mounting brackets 205 and filter screens 206 are provided and connected to each other. By pulling the mounting bracket 205, the mounting bracket 205 drives the filter screen 206 and adjacent mounting brackets 205 to unfold, so that the mounting bracket 205 and filter screen 206 unfold into a semi-circular shape. The limiting groove 207 passes through the limiting block 209, and the elasticity of the torsion spring 210 drives the limiting block 209 to rotate 90 degrees. The limiting block 209 limits the mounting bracket 205, so that the semi-circular whole formed by the mounting bracket 205 and filter screen 206 is fixed on the mounting base 1. The meter 101 is located at the center of the mounting base 1. The meter 101 is encased by the mounting bracket 205 and the filter 206, preventing external dust from contacting the terminals of the meter 101 and avoiding safety hazards caused by dust adhering to the terminals. The filter 206 is breathable, which is different from the existing technology where installing a sealed shell would affect the heat dissipation of the meter 101. The filter 206 can also be used to shade the meter 101, reducing the lifespan of the meter 101 caused by direct sunlight. The unfolded mounting bracket 205 can be used to protect the meter 101 and reduce the damage caused by external impacts. Furthermore, a motor 211 is provided on the mounting base 1, and a drive shaft 212 is provided at the output end of the motor 211. The drive shaft 212 is rotatably mounted on the mounting base 1, and a drive gear 213 is provided on the drive shaft 212. A transmission gear ring 214 is rotatably mounted on the mounting base 1. The drive gear 213 and the transmission gear ring 214 are mutually adapted. A rotating ring 201 is rotatably mounted on the mounting base 1 and is mounted on the transmission gear ring 214. Start motor 211, motor 211 drives drive shaft 212 to rotate, drive shaft 212 drives drive gear 213 to rotate synchronously, drive gear 213 drives transmission gear ring 214 to rotate, transmission gear ring 214 drives rotating ring 201 to rotate synchronously, rotating ring 201 drives the semi-circular whole formed by mounting bracket 205 and filter screen 206 to rotate. In this way, the position of mounting bracket 205 and filter screen 206 on rotating ring 201 is adjusted to avoid the mounting bracket 205 and filter screen 206 affecting the staff's maintenance of meter 101; The protective mechanism 2 drives the mounting bracket 205 and filter 206 to unfold and wrap around the meter 101, preventing external dust from contacting the terminals of the meter 101. This avoids the safety hazards caused by dust adhering to the terminals and improves the safety of the equipment. By driving the mounting bracket 205 and filter 206 to unfold and fix them on the mounting base 1, the frame formed by the mounting bracket 205 and filter 206 protects the meter 101, reducing the possibility of damage to the meter 101 due to external impacts. This preventative protection of the meter 101 extends its service life.

[0027] Example 2 further optimizes the protective smart energy meter provided in Example 1, specifically, as follows: Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an air outlet pipe 215 is fixedly passed through the end of the meter 101, and an air inlet pipe 216 is fixedly passed through the bottom of the meter 101. A hollow seat 217 is threadedly connected to the air outlet pipe 215, and a cleaning hole 218 is provided on the hollow seat 217. When air enters through the air inlet pipe 216 and is discharged into the meter 101, the air passes through the meter 101 and is discharged from the air outlet pipe 215. The air then enters the hollow base 217 and is discharged from the cleaning hole 218. This method provides air cooling to the inside of the meter 101, reducing its internal temperature and minimizing the risk of component aging due to overheating. This improves the lifespan of the meter 101. Figure 3As shown, the air discharged through the cleaning hole 218 cleans the surface of the filter screen 206, preventing dust from adhering to the filter screen 206 and preventing the heat of the meter 101 from being discharged to the outside. This cleaning method reduces damage to the filter screen 206 and extends its service life. Furthermore, multiple cleaning holes 218 are provided, and the multiple cleaning holes 218 are arranged in a linear array on the hollow base 217; By linearly arranging the cleaning holes 218 on the hollow base 217 and cooperating with the rotation of the mounting bracket 205, rotating ring 201 and filter screen 206, the air discharged from the cleaning holes 218 can fully and automatically clean the filter screen 206, thus improving the cleaning efficiency. Furthermore, a transmission cylinder 219 is provided on the mounting base 1, and a piston 220 is slidably provided inside the transmission cylinder 219. A connecting pipe 221 is fixedly passed through the mounting base 1 and the transmission cylinder 219. The end of the air inlet pipe 216 away from the meter 101 is fixedly passed through the transmission cylinder 219. A one-way valve 222 is provided on the air inlet pipe 216, and a one-way valve 223 is provided on the connecting pipe 221. One-way valve 222 is used to discharge air from the transmission cylinder 219 into the meter 101 through the air inlet pipe 216 for one-way flow. One-way valve 223 is used to discharge outside air into the transmission cylinder 219 through the connecting pipe 221 for one-way flow. When piston 220 slides along the transmission cylinder 219 toward one-way valve 222, piston 220 discharges air from the transmission cylinder 219 into the meter 101 through one-way valve 222 and air inlet pipe 216. When piston 220 slides back to its original position along the transmission cylinder 219, outside air enters the transmission cylinder 219 through one-way valve 223 and connecting pipe 221. The reciprocating sliding of piston 220 along the transmission cylinder 219 allows outside air to enter the meter 101. Figure 4 As shown, the connecting pipe 221 is located within the area enclosed by the filter screen 206 and the mounting bracket 205, so the air entering the meter 101 does not contain dust, thus preventing external dust from entering the meter 101 and causing equipment failure. Furthermore, an arc-shaped block 224 is provided on the transmission gear ring 214, a pusher column 225 is slidably provided on the transmission cylinder 219, the pusher column 225 is provided on the piston 220, and springs 226 are provided on the corresponding surfaces of the piston 220 and the transmission cylinder 219. Furthermore, a ball bearing 227 is rotatably mounted on the push column 225, and the ball bearing 227 is compatible with the arc-shaped block 224; When the transmission gear ring 214 rotates, it drives the arc-shaped block 224 to rotate synchronously, such as Figure 6As shown, the arc block 224 rotates and squeezes the ball 227. The ball 227 is squeezed and displaced. The ball 227 drives the push pin 225 and the piston 220 to move synchronously. The elasticity of the spring 226 drives the ball 227, the push pin 225 and the piston 220 to return to their original positions. This realizes the reciprocating sliding of the piston 220 along the transmission cylinder 219. The ball 227 reduces the friction with the arc block 224. The protective mechanism 2 drives filtered air to cool the inside of the meter 101, reducing the internal temperature of the meter 101 and minimizing the risk of component aging due to excessive internal temperature. This extends the lifespan of the meter 101. The air cooling inside the meter 101 also cleans the surface of the filter screen 206, preventing dust buildup that could prevent heat from dissipating. This cleaning method reduces damage to the filter screen 206 and extends its lifespan.

[0028] The protective smart energy meter provided by this invention is used as follows: In use, by pulling the mounting bracket 205, the mounting bracket 205 drives the filter screen 206 and the adjacent mounting bracket 205 to unfold, so that the mounting bracket 205 and the filter screen 206 unfold into a semi-circular shape. The filter screen 206 passes through the limiting groove 207 and the limiting block 209, and the limiting block 209 rotates 90 degrees due to the elasticity of the torsion spring 210. The limiting block 209 limits the mounting bracket 205, so that the semi-circular whole formed by the mounting bracket 205 and the filter screen 206 is fixed on the mounting base 1. The meter 101 is located at the center of the mounting base 1. Net 206 encloses meter 101, preventing external dust from contacting the terminals of meter 101 and avoiding safety hazards caused by dust accumulation on the terminals. Motor 211 is started, driving drive shaft 212 to rotate. Drive shaft 212 drives drive gear 213 to rotate synchronously, drive gear 213 drives transmission gear ring 214 to rotate, transmission gear ring 214 drives rotating ring 201 to rotate synchronously, and transmission gear ring 214 drives arc block 224 to rotate synchronously. Arc block 224 rotates and squeezes ball bearing 227, causing ball bearing 227 to be squeezed and... Displacement: Ball bearing 227 drives the actuating pin 225 and piston 220 to move synchronously. The elasticity of spring 226 drives ball bearing 227, actuating pin 225, and piston 220 to reset, achieving reciprocating sliding of piston 220 along transmission cylinder 219. When piston 220 slides along transmission cylinder 219 towards one-way valve 222, piston 220 discharges air from transmission cylinder 219 into meter 101 through one-way valve 222 and air inlet pipe 216. When piston 220 slides back to its original position along transmission cylinder 219, outside air is discharged through one-way valve 223 and connecting... The connecting pipe 221 enters the transmission cylinder 219. When air enters the inlet pipe 216 and is discharged into the meter 101, the air passes through the meter 101 and is discharged from the outlet pipe 215. The air enters the hollow seat 217 and is discharged from the cleaning hole 218. In this way, the inside of the meter 101 is cooled by air, and the temperature inside the meter 101 is reduced. The cleaning holes 218 are linearly arranged on the hollow seat 217 and cooperate with the rotation of the mounting bracket 205, the rotating ring 201 and the filter screen 206, so that the air discharged from the cleaning holes 218 can automatically clean the filter screen 206.
