Description

Technical Field

[0001] This invention belongs to the field of smart meter box technology, and specifically relates to a smart meter box and its usage method. Background Technology

[0002] An electricity meter box is a device used to install and protect electricity meters, primarily for real-time monitoring and management of electricity consumption. Electricity metering and protection functions are achieved by connecting the meters inside the box to wires. The following technical issues exist during the use of the meters inside the box; First, the cable inlet of the electricity meter is the node where current enters and exits the meter, and the wires are connected here through terminals or connectors. According to Joule's law, current generates heat when it passes through the resistance of a conductor, causing the cable inlet of the electricity meter to heat up during operation.

[0003] Secondly, the electricity meter is connected to the live wire, neutral wire, and ground wire through cable inlets. Since the contact resistance of the live wire is greater than that of the neutral wire, according to Joule's law Q=I²Rt, the heat generated at the connection between the meter and the live wire is greater than that at the connection between the meter and the neutral wire. This results in uneven heating at the connection points of the meter and the live and neutral wires, causing a drop in the load voltage at the live wire connection end, affecting the accuracy of the meter reading, and in more serious cases, even causing a fire at the live wire connection end. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a smart meter box and its usage method, thereby solving the technical problems in the prior art.

[0005] The objective of this invention can be achieved through the following technical solution: A smart meter box, comprising a box body, a wiring harness box and a sealed box installed inside the box body, an electricity meter installed inside the sealed box, a wire cover installed inside the sealed box, and wires inside the wiring harness box connected to the electricity meter through the wire cover; a cable port is installed at the bottom of the electricity meter, and a fixed wire clamp and a flexible movable wire clamp are respectively installed inside the cable port, with the wires passing through the cable port and placed between the fixed wire clamp and the movable wire clamp; a heat sink is installed inside the wiring harness box, and the heat sink is connected to a fixed pipe; a gate plate is rotatably installed on the electricity meter, and a pressure sleeve is installed on the gate plate, which presses the movable wire clamp to achieve the connection between the wire and the electricity meter; a heat dissipation pipe is installed on the gate plate, and the heat dissipation pipe is connected to the fixed pipe, and the heat dissipation pipe is connected to the cable port through a heat dissipation component, so that the heat sink acts on the cable port through the fixed pipe and the heat dissipation pipe.

[0006] As a further optimization or improvement of this solution, an insertion port is provided on the energy meter, and an elastic rod is installed on the rotating shaft of the gate plate; when the pressure sleeve on the gate plate connects the wire to the energy meter by pressing the movable wire clamp, the elastic rod is inserted into the insertion port, and the heat dissipation pipe is connected to the fixed pipe.

[0007] As a further optimization or improvement of this solution, the heat dissipation component includes a sliding sleeve, on which the heat dissipation pipe is mounted, and an air pipe is slidably installed inside the sliding sleeve; an air inlet chamber and a sliding cavity located at the bottom of the air inlet chamber are opened inside the pressure sleeve, an exhaust hole one is opened inside the air inlet chamber, one end of the air pipe slides inside the sliding sleeve, and the other end slides inside the air inlet chamber, and an exhaust hole two is opened at the bottom of the air pipe, which is connected to the exhaust hole one.

[0008] As a further optimization or improvement of this solution, a connecting rod is installed at the bottom of the air pipe. The connecting rod passes through the air intake chamber and connects to the piston, which slides inside the sliding chamber.

[0009] As a further optimization or improvement of this solution, the trachea is provided with a small-diameter air hole and a large-diameter air hole located at the top of the small-diameter air hole. A rack is slidably installed inside the trachea, and a gear is rotatably installed inside the sliding sleeve. A rack is fixedly installed at the top of the trachea. The rack is connected to the rack through the gear. A baffle is installed on the rack and is slidably connected to the trachea.

[0010] As a further optimization or improvement of this solution, a sliding groove is provided on the air pipe, a perforated plate is installed on the rack, and a scraper is rotatably installed on the perforated plate; a plate scraper is installed inside the heat dissipation pipe, and the plate scraper and the scraper are engaged by an inclined surface.

[0011] As a further optimization or improvement to this solution, a moisture-absorbing silicone is installed at the bottom of the perforated plate, and a moisture-absorbing gel is installed at the bottom of the air tube.

[0012] A method for using a smart meter box, the method being applied to the smart meter box as described above, the method comprising the following steps: Step S1: Pass the wire through the outside into the wiring harness box, and then insert the wire through the wire cover into the cable port at the bottom of the electricity meter; Step S2: Rotate the gate to insert the pressure sleeve on the gate into the cable port and press the movable wire clamp. The connection between the wire and the electricity meter is achieved by pressing the movable wire clamp with the pressure sleeve. Step S3: After the wire is connected to the electricity meter, the elastic rod on the gate is inserted into the socket, thereby limiting the gate and connecting it to the fixed pipe through the heat dissipation pipe. Step S4: Activate the built-in heat sink of the wire harness box. The airflow generated by the heat sink enters the fixed pipe and the heat sink pipe. The airflow inside the heat sink pipe enters the cable port through the heat dissipation component.

[0013] The beneficial effects of this invention are: (1) The present invention uses a heat sink built into the wire harness box. The airflow generated by the heat sink enters the fixed pipe and the heat sink pipe. The airflow inside the heat sink pipe enters the cable port through the heat dissipation component, thereby achieving heat dissipation of the internal connector of the cable port. Specifically, during the heat dissipation process at the connection between the electricity meter and the neutral wire, the airflow inside the heat dissipation pipe enters the air pipe through the small-diameter air holes on the air pipe, and the airflow inside the air pipe is discharged through exhaust hole two and enters the scraper through exhaust hole one, so that the airflow acts on the connection between the electricity meter and the wire, thereby achieving heat dissipation at the connection between the electricity meter and the neutral wire. When cooling the part where the electricity meter is connected to the live wire, the air pipe moves upward, increasing the cavity space between the air pipe and the air inlet. At this time, the airflow through the exhaust port increases, thereby improving the heat dissipation efficiency of the part where the electricity meter is connected to the live wire. This ensures that the temperature of each cable port of the electricity meter is uniform, and avoids the voltage drop at the load end of the connection between the electricity meter and the live wire, which would affect the accuracy of the electricity meter measurement.

[0014] (2) During the upward movement of the air tube, through the transmission relationship between rack 2, gear and rack 1, the air tube drives the rack to move downward, so that rack 1 drives the baffle to move downward synchronously. The baffle blocks the small-diameter air hole, so that the airflow inside the heat dissipation tube enters the air tube through the large-diameter air hole, thereby increasing the airflow in the air tube.

[0015] Existing technologies improve heat dissipation efficiency at the connection between the electricity meter and the live wire by increasing the amount of gas entering the meter; however, this method is limited by the amount of gas discharged. In contrast, this invention increases both the amount of air entering the duct and the amount of air exiting through the exhaust port, thus avoiding the limitation of gas discharge on the heat dissipation efficiency at the connection point of the electricity meter.

[0016] (3) The airflow acting on the connection between the power meter and the live wire is relatively large, and the air humidity in this part is relatively high, which reduces the dehumidification efficiency of the moisture-absorbing gel. Based on this, the present invention moves the air tube upward to drive the rack downward, so that the rack moves the baffle downward in sync. When the baffle moves to the bottom, the baffle blocks the small-diameter air hole. At this time, the airflow inside the heat dissipation pipe enters the air tube through the large-diameter air hole. The airflow first undergoes preliminary dehumidification through the mesh plate and moisture-absorbing silica gel, and then undergoes secondary dehumidification through the moisture-absorbing gel, thereby improving the dryness of the airflow acting on the connection between the power meter and the live wire.

[0017] (4) In this invention, the air tube moves upward, causing the rack to move downward. The air tube and the rack move relative to each other, and the scraper on the rack scrapes away the debris on the air tube. As the rack moves downward, the scraper and the plate scraper cooperate, so that the inner wall of the scraper adheres to the outer wall of the plate scraper. As the rack continues to move downward, the scraper rotates, and the plate scraper scrapes the impurities on the scraper onto the bottom of the heat dissipation tube. By opening the exhaust port at the end of the fixed tube, the impurities are discharged from the inside of the heat dissipation tube, thereby cleaning the impurities attached to the outer wall of the air tube.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0033] See Figures 1-8 A smart meter box includes a box body 1, a wiring harness box 2 and a sealed box 3 installed inside the box body 1, an electricity meter 4 installed inside the sealed box 3, and a wire cover 7 installed inside the sealed box 3. A wire 16 inside the wiring harness box 2 is connected to the electricity meter 4 through the wire cover 7. A cable port 12 is installed at the bottom of the electricity meter 4. A fixed wire clamp 14 and a flexible movable wire clamp 15 are respectively installed inside the cable port 12. The wire 16 passes through the cable port 12 and is placed between the fixed wire clamp 14 and the movable wire clamp 15. A heat sink is installed inside the wiring harness box 2, and the heat sink is connected to a fixed pipe 5. A gate plate 9 is rotatably installed on the electricity meter 4, and a pressure sleeve 13 is installed on the gate plate 9. The connection between the wire 16 and the electricity meter 4 is achieved by the pressure sleeve 13 pressing the movable wire clamp 15. A heat dissipation pipe 6 is installed on the gate plate 9, and the heat dissipation pipe 6 is connected to the fixed pipe 5. The heat dissipation pipe 6 is connected to the cable port 12 through a heat dissipation component 8, so that the heat sink acts on the cable port 12 through the fixed pipe 5 and the heat dissipation pipe 6.

[0034] Specifically, the electricity meter 4 has a socket 10, and an elastic rod 11 is installed on the rotating shaft of the gate plate 9; when the pressure sleeve 13 on the gate plate 9 connects the wire 16 to the electricity meter 4 by pressing the movable wire clamp 15, the elastic rod 11 is inserted into the socket 10, and the heat dissipation pipe 6 is connected to the fixed pipe 5.

[0035] Specifically, the heat dissipation assembly 8 includes a sliding sleeve 801, on which the heat dissipation pipe 6 is mounted. An air pipe 802 is slidably installed inside the sliding sleeve 801. An air inlet chamber 807 and a sliding cavity 806 located at the bottom of the air inlet chamber 807 are provided inside the pressure sleeve 13. An exhaust port 803 is provided inside the air inlet chamber 807. One end of the air pipe 802 slides inside the sliding sleeve 801, and the other end slides inside the air inlet chamber 807. An exhaust port 817 is provided at the bottom of the air pipe 802, and the exhaust port 817 communicates with the exhaust port 803.

[0036] Specifically, a connecting rod 805 is installed at the bottom of the air pipe 802. The connecting rod 805 passes through the air intake chamber 807 and connects to the piston 804. The piston 804 slides inside the sliding chamber 806.

[0037] Specifically, the air pipe 802 has a small-diameter air hole 809 and a large-diameter air hole 810 located at the top of the small-diameter air hole 809. A rack 1 813 is slidably installed inside the air pipe 802, a gear 815 is rotatably installed inside the sliding sleeve 801, and a rack 2 814 is fixedly installed at the top of the air pipe 802. The rack 2 814 is connected to the rack 1 813 through the gear 815. A baffle 811 is installed on the rack 1 813, and the baffle 811 is slidably connected to the air pipe 802.

[0038] It should be noted that the heat sink built into the wire harness box 2 is connected to the outside at one end and to the fixed pipe 5 at the other end. When the heat sink is working, it will draw outside air into the fixed pipe 5, the heat dissipation pipe 6 and the cable port 12, thereby achieving heat dissipation. A spring 17 is installed on the movable wire clamp 15.

[0039] It should be noted that during the wiring process of the electricity meter 4, the wire 16 needs to be first threaded into the wiring harness box 2 from the outside, and then the wire 16 is inserted into the cable port 12 at the bottom of the electricity meter 4 through the wire cover 7. See [link / reference]. Figure 7 As shown. Rotate the gate 9 so that the pressure sleeve 13 on the gate 9 is inserted into the cable port 12 and the movable wire clamp 15 is pressed. The wire 16 is connected to the energy meter 4 by the pressure sleeve 13 pressing the movable wire clamp 15. After the wire 16 is connected to the energy meter 4, the elastic rod 11 on the gate 9 is inserted into the socket 10, thereby limiting the gate 9. At the same time, the heat dissipation pipe 6 is connected to the fixed pipe 5. The built-in heat sink of the wire harness box 2 is activated, and the airflow generated by the heat sink enters the fixed pipe 5 and the heat sink 6. The airflow inside the heat sink 6 enters the cable port 12 through the heat dissipation component 8, thereby dissipating heat from the internal connectors of the cable port 12.

[0040] Specifically, conductor 16 includes a live wire, a neutral wire, and a ground wire. Due to the relatively low operating heat at the connection point between the electricity meter 4 and the neutral wire, the increase in air pressure in the air chamber between the movable clamp 15 and the piston 804 is minimal. The piston 804 causes the air pipe 802 to move slightly upwards or remain stationary. (See [reference]). Figure 8 At this time, the airflow inside the heat dissipation pipe 6 enters the air pipe 802 through the small diameter air hole 809 on the air pipe 802, and the airflow inside the air pipe 802 is discharged through the second exhaust hole 817 and enters the cable port 12 through the first exhaust hole 803, so that the airflow acts on the connection part between the energy meter 4 and the wire 16, thereby realizing the heat dissipation of the part where the energy meter 4 is connected to the neutral wire.

[0041] The connection point between the electricity meter 4 and the live wire generates significant heat during operation, resulting in a high temperature for the movable clamp 15. (See [reference needed]). Figure 7At this time, the air pressure in the air chamber between the movable clamp 15 and the piston 804 gradually increases. The air pressure drives the piston 804, connecting rod 805 and air pipe 802 to move upward. During the upward movement of air pipe 802, the cavity space between air pipe 802 and air inlet 807 increases. At this time, the airflow discharged through exhaust port 803 increases, thereby improving the heat dissipation efficiency of the part where the energy meter 4 is connected to the live wire, ensuring that the temperature of each cable port 12 of the energy meter 4 is uniform, and avoiding the voltage drop at the load end of the connection between the energy meter 4 and the live wire, which would affect the accuracy of the energy meter 4. During the upward movement of the air pipe 802, through the transmission relationship between rack 2 814, gear 815 and rack 1 813, the air pipe 802 drives rack 1 813 to move downward, causing rack 1 813 to drive baffle 811 to move downward synchronously. Baffle 811 blocks the small-diameter air hole 809, allowing the airflow inside the heat dissipation pipe 6 to enter the air pipe 802 through the large-diameter air hole 810, thereby increasing the airflow into the air pipe 802.

[0042] Existing technologies improve heat dissipation efficiency at the connection between the electricity meter 4 and the live wire by increasing the amount of gas entering the connection; however, this method is limited by the amount of gas exiting the connection. In contrast, this invention increases the airflow into the air pipe 802 and simultaneously increases the airflow exit from the exhaust port 803, thus avoiding the limitation of gas exiting the heat dissipation efficiency at the connection of the electricity meter 4. The heat dissipation component 8 is made of lightweight materials, such as high-strength plastics; the racks 813 and 814 offer high transmission accuracy and low resistance.

[0043] See Figures 8-12 The air pipe 802 is provided with a sliding groove 816, the rack 813 is equipped with a mesh plate 820, and a scraper 812 is rotatably installed on the mesh plate 820; a plate scraper 808 is installed inside the heat dissipation pipe 6, and the plate scraper 808 and the scraper 812 are engaged by an inclined surface.

[0044] Specifically, a moisture-absorbing silicone 819 is installed at the bottom of the perforated plate 820, and a moisture-absorbing gel 818 is installed at the bottom of the air tube 802.

[0045] It should be noted that the sealed box 3 is a sealed environment to prevent rainwater from seeping into the electricity meter 4.

[0046] It should be noted that if the ambient air humidity is high or the environment is rainy, the high humidity air will be transported through the radiator to the inside of the cable port 12, causing water droplets to form at the connection between the wire 16 and the electricity meter 4. This can easily lead to moisture-induced short circuits in the internal electrical components of the electricity meter 4. Therefore, this invention installs a moisture-absorbing gel 818 at the bottom of the air pipe 802. The air is dehumidified by the moisture-absorbing gel 818, thereby ensuring the dryness of the radiating air.

[0047] As can be seen from the above embodiments, the airflow acting on the connection between the electricity meter 4 and the live wire is relatively large, and the air humidity in this area is high, reducing the dehumidification efficiency of the moisture-absorbing gel 818. Therefore, this invention moves the air pipe 802 upwards, causing the rack 813 to move downwards, which in turn moves the baffle 811 downwards simultaneously. When the baffle 811 reaches its lowest point, it blocks the small-diameter air hole 809. At this time, the airflow inside the heat dissipation pipe 6 enters the air pipe 802 through the large-diameter air hole 810. (See also...) Figure 12 The airflow first undergoes preliminary dehumidification through the perforated plate 820 and the moisture-absorbing silica gel 819, and then undergoes secondary dehumidification through the moisture-absorbing gel 818, thereby improving the dryness of the airflow acting on the connection between the electricity meter 4 and the live wire.

[0048] It should be noted that if the outside air contains impurities, these impurities will adhere to the outer wall of the air pipe 802, affecting heat dissipation efficiency. Therefore, this invention uses the upward movement of the air pipe 802 to drive the rack 813 downward. The relative movement of the air pipe 802 and rack 813 allows the scraper 812 on the rack 813 to scrape away impurities from the air pipe 802. As the rack 813 moves downward, the scraper 812 cooperates with the scraper 808, causing the inner wall of the scraper 812 to adhere to the outer wall of the scraper 808. As the rack 813 continues to move downward, the scraper 812 rotates, and the scraper 808 scrapes the impurities on the scraper 812 onto the bottom of the heat dissipation pipe 6. The impurities are then discharged from the inside of the heat dissipation pipe 6 by opening the exhaust port at the tail end of the fixed pipe 5.

[0049] It should be noted that the first end of the fixed tube 5 is connected to the heat sink, and the second end is connected to an openable / closable port. In the heat dissipation state, the second end of the fixed tube 5 is closed, and the airflow generated by the heat sink acts on the cable port 12 through the heat dissipation pipe 6 and the heat dissipation assembly 8. In the cleaning state, the second end of the fixed tube 5 is open, and the airflow generated by the heat sink discharges the scraped impurities inside the heat dissipation pipe 6 through the heat dissipation pipe 6. The connection is sealed to the movable cable clamp 15 via the sealing gasket at the bottom of the pressure sleeve 13.

[0050] Please see Figures 1-8 As shown, the present invention provides a method for using a smart meter box. The method is applied to the smart meter box described in the above embodiments and includes the following steps: Step S1: Pass the wire 16 through the outside into the wire harness box 2, and then insert the wire 16 through the wire cover 7 into the cable port 12 at the bottom of the electricity meter 4; Step S2: Rotate the gate 9 so that the pressure sleeve 13 on the gate 9 is inserted into the cable port 12 and the movable wire clamp 15 is pressed. The connection between the wire 16 and the energy meter 4 is achieved by the pressure sleeve 13 pressing the movable wire clamp 15. Step S3: After the wire 16 is connected to the electricity meter 4, the elastic rod 11 on the gate 9 is inserted into the socket 10, thereby limiting the gate 9, and connecting it to the fixed pipe 5 through the heat dissipation pipe 6. Step S4: Activate the built-in heat sink of the wire harness box 2. The airflow generated by the heat sink enters the fixed pipe 5 and the heat sink 6. The airflow inside the heat sink 6 enters the cable port 12 through the heat dissipation component 8.

[0051] The implementation principle of this invention is as follows: During the wiring process for the electricity meter 4, the wire 16 needs to be threaded from the outside into the wiring harness box 2 first. Then, the wire 16 is inserted through the wire cover 7 into the cable port 12 at the bottom of the electricity meter 4. See [link / reference needed]. Figure 7 As shown. Rotate the gate 9 so that the pressure sleeve 13 on the gate 9 is inserted into the cable port 12 and the movable wire clamp 15 is pressed. The wire 16 is connected to the energy meter 4 by the pressure sleeve 13 pressing the movable wire clamp 15. After the wire 16 is connected to the energy meter 4, the elastic rod 11 on the gate 9 is inserted into the socket 10, thereby limiting the gate 9. At the same time, the heat dissipation pipe 6 is connected to the fixed pipe 5. The built-in heat sink of the wire harness box 2 is activated, and the airflow generated by the heat sink enters the fixed pipe 5 and the heat sink 6. The airflow inside the heat sink 6 enters the cable port 12 through the heat dissipation component 8, thereby dissipating heat from the internal connectors of the cable port 12.

[0052] Specifically, conductor 16 includes a live wire, a neutral wire, and a ground wire. Due to the relatively low operating heat at the connection point between the electricity meter 4 and the neutral wire, the increase in air pressure in the air chamber between the movable clamp 15 and the piston 804 is minimal. The piston 804 causes the air pipe 802 to move slightly upwards or remain stationary. (See [reference]). Figure 8 At this time, the airflow inside the heat dissipation pipe 6 enters the air pipe 802 through the small diameter air hole 809 on the air pipe 802, and the airflow inside the air pipe 802 is discharged through the second exhaust hole 817 and enters the cable port 12 through the first exhaust hole 803, so that the airflow acts on the connection part between the energy meter 4 and the wire 16, thereby realizing the heat dissipation of the part where the energy meter 4 is connected to the neutral wire.

[0053] The connection point between the electricity meter 4 and the live wire generates significant heat during operation, resulting in a high temperature for the movable clamp 15. (See [reference needed]). Figure 7 At this time, the air pressure in the air chamber between the movable clamp 15 and the piston 804 gradually increases. The air pressure drives the piston 804, connecting rod 805 and air pipe 802 to move upward. During the upward movement of air pipe 802, the cavity space between air pipe 802 and air inlet 807 increases. At this time, the airflow discharged through exhaust port 803 increases, thereby improving the heat dissipation efficiency of the part where the energy meter 4 is connected to the live wire, ensuring that the temperature of each cable port 12 of the energy meter 4 is uniform, and avoiding the voltage drop at the load end of the connection between the energy meter 4 and the live wire, which would affect the accuracy of the energy meter 4. During the upward movement of the air pipe 802, through the transmission relationship between rack 2 814, gear 815 and rack 1 813, the air pipe 802 drives rack 1 813 to move downward, causing rack 1 813 to drive baffle 811 to move downward synchronously. Baffle 811 blocks the small-diameter air hole 809, allowing the airflow inside the heat dissipation pipe 6 to enter the air pipe 802 through the large-diameter air hole 810, thereby increasing the airflow into the air pipe 802.

[0054] Existing technologies improve heat dissipation efficiency at the connection between the electricity meter 4 and the live wire by increasing the amount of gas entering the connection. However, this method is limited by the amount of gas exiting the connection. In contrast, this invention increases the amount of air entering the air pipe 802 and simultaneously increases the amount of air exiting the exhaust port 803, thus avoiding the limitation of gas exiting the heat dissipation efficiency at the connection of the electricity meter 4.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
