Description

Technical Field

[0001] The present invention relates to the technical field of electric energy metering boxes, and particularly to an electric energy metering box based on the Internet of Things, a component replacement method without power interruption, and a method therefor. Background Technique

[0002] Electric energy metering boxes have always occupied an important position in the power system. With the development of power technology, electric energy metering boxes are gradually evolving towards intelligence. Electric energy metering boxes are usually installed in outdoor environments, and their internal heat dissipation problems are greatly affected by the external environment. Poor heat dissipation will affect the performance of internal electrical components.

[0003] Chinese Patent Publication No. CN111077366A discloses an electric energy metering system and its protection device, including an electric energy metering box and an electric energy metering system inside the electric energy metering box. It also includes a protection box. A partition plate is horizontally arranged inside the protection box, and the partition plate is fixed on the inner wall of the protection box. The lower side of the partition plate is an installation cavity, and an installation mechanism for installing and positioning the electric energy metering box is arranged inside the installation cavity. The upper side of the partition plate is a heat dissipation cavity, and a multi-gear adjustable heat dissipation structure for heat dissipation is arranged inside the heat dissipation cavity. A plurality of ventilation holes are opened on the partition plate.

[0004] Chinese Patent Publication No. CN207096297U discloses a device for replacing an electric energy meter without power interruption and without loss of electric energy, including a live wire access unit, a live wire output unit, a neutral wire access unit, and a neutral wire output unit. The live wire access unit, the live wire output unit, the neutral wire access unit, and the neutral wire output unit respectively include a conductive current guiding seat, a conductive positioning seat arranged above the conductive current guiding seat, a conductive support arranged above the conductive positioning seat, and a conductive roller arranged on the conductive support. Four radial through holes are arranged on the circumferential surface of the conductive roller, a vertical through hole corresponding to the radial through hole is arranged on the bottom surface of the conductive support, a vertical slot communicating with the vertical through hole is arranged inside the conductive positioning seat, and a cable insertion port is arranged on the bottom surface of the conductive current guiding seat.

[0005] The above-mentioned electric energy metering box solves the internal heat dissipation problem by using a driving motor to drive the rotation of a driven gear and fan blades for heat dissipation. Since the electrical components in the electric energy metering box are attached to the inner wall of the box after installation, during the rotation of the fan blades, the generated heat dissipation airflow is difficult to act between the electrical components and the box body, resulting in local overheating inside the box and low cooling efficiency inside the box.

[0006] In addition, when the external environment of the box is humid, due to the lack of control of moisture, at this time, the heat dissipation gas will carry a large amount of moisture into the box, which will affect the stable operation of the power system. In addition, the replacement and maintenance of the electric energy meter need to be carried out manually. When a fault signal appears during the use of the electric energy meter, since the maintenance personnel cannot maintain the electric energy meter and the power grid in time, it will affect the normal power consumption of the power consumption unit and bring inconvenience to the power consumption unit.

[0007] Therefore, a power metering box, a component for replacing without power interruption, and a method based on the Internet of Things are proposed to solve the above problems. Summary of the Invention

[0023] Optionally, the heat sink is arranged inside the hollow inner layer, the elbow corresponds to and cooperates with the heat sink, and a solenoid valve is arranged at one end of the elbow far away from the connector.

[0032] S4. Finally, reinstall and fix the door of the box body to complete the power-off replacement of the electricity meter.

[0033] Technical effects and advantages of the present invention:

[0034] 1. The present invention utilizes the gap between the electrical components and the partition to increase the flow rate of the gas in the gap. After the fan is started, the negative pressure of the fan is used to exchange the gas in the box body with the external low-temperature gas and then discharge it out through the heat dissipation port, accelerating the heat dissipation speed inside the box body and avoiding excessive local heat in the box body.

[0035] 2. The present invention enables the box body to have a liquid cooling function by supplying the low-temperature water in the water tank into the elbow pipe through a water pump, uses the low-temperature water to exchange heat with the heat in the box body, and cooperates with the fan to accelerate the continuous discharge of the high-temperature gas in the box body, improving the cooling speed in the box body.

[0036] 3. The present invention drives the expansion and contraction of the partition by an electric telescopic rod, can adjust the position of the partition, and then controls the connection state between the plug post and the through hole. After the partition contracts, the external humid gas will be isolated and cannot enter the inside of the box body, thereby ensuring the stable operation of the electrical components in the box body. During this process, the heat generated by the electrical components exchanges heat with the low-temperature water body in the elbow pipe for heat dissipation.

[0037] 4. When a power-off fault signal appears in the electricity meter in the present invention, the partition and multiple electrical components on the front side are driven to move forward synchronously by the electric telescopic rod, so that the power-on jack and the conductive plug are docked, ensuring that the power supply line of the power consumption unit is not affected by the power-off, and at the same time ensuring the heat dissipation gap between the electrical components and the partition.

[0038] 5. The plug post with a gradually increasing length from bottom to top in the present invention, according to the detected temperature inside the box body, when the temperature inside the box body is relatively low, drives the partition to expand and contract by the electric telescopic rod, controls the docking quantity between the plug post and the through hole, and further adjusts the intake air volume entering the box body according to the temperature inside the box body, thereby controlling the speed of heat dissipation from the inside of the box body to keep the inside of the box body within a preset standard temperature range and ensuring the stability of the start and operation of the electrical components.

Detailed implementation manners

[0050] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0051] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited by the specific embodiments disclosed below.

[0052] Embodiment 1

[0053] Please refer to Figures 1-10 , this embodiment discloses an electric energy metering box based on the Internet of Things, which includes a box body 1 and an electric energy metering system disposed inside the box body 1. A box door is provided on the front side of the box body 1, and an observation window is provided on the box door. The electric energy metering system includes an electronic current transformer, a merging unit, and an electric meter 3. The electric meter 3 is an Internet of Things intelligent electric meter, and the electric meter 3 includes a digital signal processing module, a central control module, a communication transmission module, a data storage module, and a display module.

[0054] The inner side of the box body 1 is provided with a hollow inner layer 101 and a partition 102. A heat dissipation component 5 is provided on the inner side of the hollow inner layer 101, and a temperature reduction component 6 is provided on the rear side of the partition 102. The heat dissipation component 5 is used to discharge the hot gas in the box body 1 to the outside, and the temperature reduction component 6 is used to reduce the temperature in the box body 1. A temperature sensor is provided on the rear side of the partition 102.

[0055] An air inlet 104 is formed on the rear sides of the box body 1 and the hollow inner layer 101, and a filtering component 7 is installed in the air inlet 104. External gas enters the box body 1 through the air inlet 104, and the filtering component 7 filters the impurities in the external gas.

[0056] As Figure 2 , Figure 7 and Figure 9 shown, specifically, the heat dissipation component 5 includes a heat dissipation pipe 501, a blower 502 is provided on the heat dissipation pipe 501. One end of the heat dissipation pipe 501 is communicated with the hollow inner layer 101, and the other end of the heat dissipation pipe 501 is provided with a cover body 503. A plurality of heat dissipation openings 103 are provided on one side of the box body 1, and the cover body 503 is correspondingly communicated and matched with the heat dissipation openings 103;

[0057] A plurality of through holes 1022 are formed on the partition 102. After the external gas passes through the air inlet 104, it first enters the chamber between the partition 102 and the hollow inner layer 101, and then drives the heat in the box body 1 through the heat dissipation pipe 501 and discharges it to the outside under the drive of the blower 502.

[0058] As Figure 2 , Figure 7 , Figure 9 and Figure 10As shown in the figure, specifically, a cooling component 6 is provided at the rear side of the partition plate 102. The cooling component 6 includes a heat dissipation rack 601 provided inside the hollow inner layer 101 and a bent pipe 602 located on the heat dissipation rack 601. One end of the bent pipe 602 penetrates through the hollow inner layer 101 and the box body 1 and is communicated with a connector 603. One end of the connector 603 is provided with a water tank 604. The water tank 604 can be buried underground for heat preservation or a semiconductor refrigeration sheet can be arranged in the water tank 604. The refrigeration end of the semiconductor refrigeration sheet is located inside the water tank 604 to keep the water body in the water tank 604 at a low temperature. A water pump is provided on the connector 603, and the water pump is used to transport the low-temperature water in the water tank 604 into the bent pipe 602. The low-temperature water exchanges heat with the heat in the box body 1 through the bent pipe 602.

[0059] Wherein, a solenoid valve is provided at one end of the bent pipe 602 away from the connector 603. When the water pump transports the low-temperature water upward through the bent pipe 602, the solenoid valve is opened. When the bent pipe 602 is filled with the low-temperature water, the solenoid valve is closed.

[0060] A limit mounting seat 303 is provided at the front side of the partition plate 102, and the limit mounting seat 303 is mutually adapted to the electric meter 3.

[0061] As Figure 3 and Figure 8 shown in the figure, the filtering component 7 includes an outer frame 701 and a filter plate 702. The filter plate 702 is arranged inside the outer frame 701, and an air inlet opening is formed at the bottom of the outer frame 701 and the filter plate 702.

[0062] A drainage base 201 is provided on the electric energy meter adapter 2, and a power-on jack 202 is provided on the drainage base 201. A conductive plug post 203 is provided at the top of the electric energy meter adapter 2. A power meter wiring terminal 301 is provided at the bottom of the electric meter 3. A power-on row 302 is provided at the front side of the power meter wiring terminal 301. A conductive interface 304 is opened at the bottom of the power meter wiring terminal 301. The electric meter 3 operates after the conductive plug post 203 is docked with the conductive interface 304.

[0063] Furthermore, an insulating sheath 204 is provided at a position corresponding to the conductive plug post 203 on the upper surface of the electricity meter adapter 2. A protective cover 205 is provided on the front side of the electricity meter adapter 2. A limit slot 206 is opened in the middle of the protective cover 205. A conductive module 207 is slidably connected inside the limit slot 206. A conductive plug 208 is provided on the conductive module 207. The conductive plug 208 is correspondingly matched with the power-on jack 202. A power-on indicator light 209 is provided on the conductive module 207. The insulating sheath 204 keeps the electricity meter adapter 2 and the electricity meter 3 sealed after the conductive plug post 203 is docked with the conductive interface 304, preventing external impurities from adhering to the conductive plug post 203 or entering the conductive interface 304. The limiting effect of the limit slot 206 on the conductive module 207 provides protection for the conductive plug 208, preventing the conductive plug 208 from contacting external impurities and affecting the connection stability. After the conductive plug 208 is docked with the power-on jack 202, the electricity meter 3 can be replaced without power-off.

[0064] Connection posts 605 are provided on the rear sides of the electricity meter adapter 2, the limit mounting seat 303, and the safety switch 4. Through holes are opened in the partition 102 at positions corresponding to the connection posts 605. The rear ends of the connection posts 605 penetrate through the through holes and are fixedly connected to the heat dissipation frame 601. The connection posts 605 form a gap between the electricity meter adapter 2, the limit mounting seat 303, the safety switch 4 and other electrical components and the partition 102.

[0065] As Figure 4 shown, the heat dissipation port 103 includes a support seat 1031 and a rotating plate 1032. The top of the support seat 1031 is hinged to the top of the rotating plate 1032.

[0066] During use, the temperature sensor is used to detect the temperature inside the box body 1. When the temperature reaches the preset threshold, the fan 502 is started. The negative pressure generated by the fan 502 sucks the gas inside the box body 1 and the gas outside the box body 1 into the inner cavity of the hollow inner layer 101, and then discharges the heat through the cover body 503 from the heat dissipation port 103. The gap between the electrical components and the partition 102 is used to increase the flow rate of the gas inside the gap, thereby accelerating the heat dissipation speed inside the box body 1 and preventing local overheating inside the box body 1.

[0067] To improve the heat dissipation efficiency of the fan 502 for the box body 1, when the temperature sensor detects that the temperature inside the box body 1 remains at the preset threshold, the rotation speed of the fan 502 is increased at this time. By increasing the flow rate of the gas in the heat dissipation pipe 501, the rotating plate 1032 is flipped upward with the top of the support seat 1031 as the center, increasing the size of the exhaust port of the box body 1, thereby accelerating the speed of heat discharge from the box body 1 to the outside. At the same time, the water pump pumps the low-temperature water in the water tank 604 into the elbow pipe 602 through the connector 603. During the process of pumping the low-temperature water into the elbow pipe 602, the solenoid valve at the top of the elbow pipe 602 is opened. When the elbow pipe 602 is filled with low-temperature water, the solenoid valve is closed. The low-temperature water is used for heat exchange with the heat inside the box body 1, and in cooperation with the continuous extraction of the gas inside the box body 1 by the fan 502, the cooling speed inside the box body 1 is increased.

[0068] Embodiment 2

[0069] Please refer to Figures 1-10 As shown, when the temperature inside the box body 1 rises and the external environment of the box body 1 is humid, at this time, the method of supplying external gas into the box body 1 for heat dissipation will cause a large amount of moisture to enter the box body 1, which will affect the stable operation of the power system. In this regard, the following embodiments are provided to solve this problem:

[0070] The hollow inner layer 101 is slidably and sealingly connected to the partition plate 102. An electric telescopic rod 1021 is provided at the rear side inside the hollow inner layer 101. The telescopic end of the electric telescopic rod 1021 is fixedly connected to the partition plate 102. A plug post 703 is provided on the filter plate 702, and the plug post 703 is correspondingly matched with the through hole 1022. The partition plate 102 is controlled to move back and forth by the electric telescopic rod 1021, and a humidity sensor is provided at the rear side of the partition plate 102.

[0071] During use, the humidity sensor detects the humidity of the gas entering the box body 1 through the filter plate 702. When the humidity sensor detects that the humidity in the gas exceeds the preset threshold, the partition plate 102 is driven to contract by the electric telescopic rod 1021, so that the partition plate 102 approaches the filter plate 702, and further the plug post 703 blocks the through hole 1022, and the external humid gas cannot enter the inside of the box body 1. The fan 502 is turned off, and then the water pump transports the low-temperature water in the water tank 604 to the elbow pipe 602, and heat exchange is carried out with the heat inside the box body 1 through the elbow pipe 602 and the heat dissipation frame 601. The water pump is a two-way water pump. During this process, the water body in the elbow pipe 602 can be recovered to the water tank 604 by the water pump, and then the low-temperature water body in the water tank 604 is supplied into the elbow pipe 602 to continue heat exchange, so as to regulate the temperature inside the box body 1.

[0072] In addition, the electricity meter 3 needs to be replaced and upgraded manually at regular intervals to maintain the overall operation efficiency and stability of the power grid. However, when a power failure fault signal appears during the use of the electricity meter 3, the maintenance personnel cannot maintain the electricity meter 3 in time, which will affect the normal power consumption of the electricity-using unit. For this reason, the following embodiments are proposed to solve the problem:

[0073] A fixing frame 2051 is provided on the outer side of the conductive module 207. The fixing frame 2051 is fixedly connected to the inner wall of the hollow inner layer 101. An electric plug for fixing the conductive module 207 is provided in the limit slot 206. When the electric plug is locked, the position of the conductive module 207 is fixed. The fixing frame 2051 keeps the conductive module 207 and the conductive plug 208 corresponding to the power-on jack 202.

[0074] The connecting column 605 is a telescopic column, and a locking mechanism is provided in the through hole of the partition plate 102. The locking mechanism is an electromagnetic lock.

[0075] During use, the conductive plug 208 on the conductive module 207 corresponds to the power-on jack 202, and the electric plug fixes the position of the conductive module 207. When a power failure fault signal appears during the use of the electricity meter 3, the fixed end of the telescopic column is fixed to the partition plate 102 through the locking mechanism. Then, after the electric telescopic rod 1021 drives the partition plate 102 and multiple electrical components on the front side to move forward synchronously, the power-on jack 202 is docked with the conductive plug 208, so that the power supply line of the electricity-using unit is not affected by the power failure, and at the same time, the heat dissipation gap between the electrical components and the partition plate 102 is ensured.

[0076] Embodiment III

[0077] Please refer to Figures 1-10 As shown in the figure, when the temperature inside the box body 1 decreases, the external gas still stably enters the box body 1 driven by the fan 502. Since the intake air volume is difficult to control, the temperature inside the box body 1 is difficult to maintain at an appropriate temperature, which affects the stability of the start-up and operation of the electrical components inside the box body 1. For this reason, the following embodiments are provided to solve the problem:

[0078] The length of the plugging column 703 gradually increases from bottom to top.

[0079] During the heat dissipation process of the box body 1 by the fan 502, when the temperature inside the box body 1 is detected by the temperature sensor to be lower than the set threshold value, it indicates that the temperature in the box body 1 has escaped from the high temperature. At this time, the partition 102 is driven to contract by the electric telescopic rod 1021. The through hole 1022 at the top of the partition 102 is first docked with the plug column 703. At this time, the through hole 1022 at the top of the partition 102 is closed by the plug column 703, and the gas entering the box body 1 will be reduced, reducing the speed of the temperature inside the box body 1 from dissipating outward. In this way, according to the temperature detected by the temperature sensor, the electric telescopic rod 1021 is used to drive the horizontal movement of the partition 102 to control the temperature inside the box body 1. Specifically, when the temperature inside the box body 1 is too low, the electric telescopic rod 1021 continues to drive the partition 102 to contract, increasing the number of plug columns 703 blocking the through hole 1022 and reducing the gas flow rate entering the box body 1. On the contrary, when the temperature inside the box body 1 rises, the electric telescopic rod 1021 pushes the partition 102, causing the multiple plug columns 703 to gradually disengage from the multiple through holes 1022 in sequence, increasing the gas flow rate entering the box body 1, and then accelerating the heat dissipation speed inside the box body 1, so that the temperature inside the box body 1 is maintained within the preset standard temperature range, ensuring the stability of the electrical components during startup operation.

[0080] In addition, during the process of the fan 502 sucking external gas into the box body 1, impurities carried in the external gas will adsorb on the inner walls of the filter plate 702, the hollow inner layer 101, and the partition 102 and are difficult to clean. For this reason, the following embodiments are proposed to solve this problem:

[0081] During use, the locking mechanism in the through hole is disconnected from the connecting column 605. The electric telescopic rod 1021 is used to drive the partition 102 to quickly contract backward, causing the partition 102 to collide and vibrate with the heat dissipation frame 601. The electric telescopic rod 1021 is used to drive the partition 102 to repeatedly and quickly expand and contract back and forth, so that the generated vibration force is continuously transmitted to the hollow inner layer 101 and the filter plate 702, shaking off the impurities inside the hollow inner layer 101 and on the filter plate 702. During this process, the fan 502 is started, and at the same time, the rotation speed of the fan 502 is increased, so that the negative pressure generated by the fan 502 discharges the impurities shaken off in the hollow inner layer 101 through the heat dissipation pipe 501 and the cover body 503 from the heat dissipation port 103, preventing the shaken-off impurities from covering the inside of the box body 1 again. The larger impurities shaken off on the filter plate 702 fall outward through the outer frame 701 and the air inlet opening at the bottom of the filter plate 702.
