Description

Technical Field

[0001] The present invention belongs to the technical field of electric energy metering boxes, and particularly relates to an electric energy metering box with a dust-proof mechanism. Background Art

[0002] An electric energy metering box is a device used to monitor and measure the use of electric energy, usually installed in the power system of buildings or industrial facilities. With the continuous development of the power system and the growth of power demand, the metering and monitoring of electric energy have become increasingly important. Traditionally, electric energy metering was carried out by mechanical electric meters, but this method has problems such as low accuracy and difficult maintenance. Therefore, with the progress of technology, the electric energy metering box emerged as a new type of electric energy metering device. The electric energy metering box usually consists of an electric energy meter, a metering controller, a communication module, a power management module, etc. It can monitor the electric energy usage in real time and transmit relevant data to the central system or monitoring platform for remote management and control. Through the electric energy metering box, power suppliers can more accurately measure the electric energy usage of users, achieve accurate billing and effective management of power resources. Generally speaking, as an important part of the modern power system, the electric energy metering box provides solutions for accurate metering, intelligent monitoring and remote management in the power industry, promoting the effective utilization of power resources and the sustainable development of energy management.

[0003] Dust isolation is an extremely important protection measure for electric energy metering boxes during use. Existing electric energy metering boxes are often interfered by dust during use and usually use dust-proof nets for isolation. Due to the intrusion of external dust, the isolation effect gradually deteriorates after long-term use, resulting in internal electrical appliances being invaded by dust and causing internal electrical appliance damage and short circuits, etc. At the same time, when cleaning the dust, the dust-proof net is usually replaced by directly disassembling it, so that the dust on the dust-proof net will cause dust to fly during the treatment process, causing a large area of dust to float into the internal electrical appliances. Not only is the dust not completely controlled, but the isolated dust will float into the interior in large quantities, resulting in an increase in internal dust, so that the isolation effect obtained during the dust isolation process is reversed, greatly reducing the safety of the electric energy metering box. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide an electric energy metering box with a dust-proof mechanism.

[0005] The technical solution adopted to solve the above technical problem is: to provide an electric energy metering box with a dust-proof mechanism, including a box body, a front cover plate is slidably connected to the front end of the box body, a cabinet door is arranged inside the front cover plate, and a plurality of ventilation openings are opened on both sides of the box body;

[0006] An internal partition is fixedly connected inside the box body, and a metering component is installed at the front end of the internal partition;

[0007] A secondary plate is fixedly connected to the rear end of the front cover plate, a partition plate is fixedly connected to the rear end of the secondary plate, another partition plate is fixedly connected to the front end of the internal partition, and a dust-proof belt is movably connected to the outer wall of the partition plate;

[0008] A dust removal mechanism is installed between the tops of the secondary plate and the internal partition, a fitting mechanism is installed inside the box body, and a tightening mechanism is installed between the bottoms of the secondary plate and the internal partition.

[0009] Furthermore, the metering component includes an input circuit located inside the box body. The output end of the input circuit is fixedly connected to a display device. The bottom of the display device is fixedly connected to a metering integrated circuit. The output end of the metering integrated circuit is fixedly connected to a current transformer, and the output end of the metering integrated circuit is fixedly connected to a voltage transformer. The current transformer, voltage transformer, and display device are fixedly connected through the metering integrated circuit.

[0010] Through the above technical solution, during use, the power consumption situation can be obtained through the metering component, which helps users understand the power consumption situation and perform electricity bill settlement, etc. Specifically, the internal components of the electric energy metering box are first connected to the input circuit through an external power supply, and then the current transformer, voltage transformer, and display device are connected through the metering integrated circuit, so that the current transformer and voltage transformer collect current and voltage signals. After being processed by the signal processing circuit, digital signals are output. The metering integrated circuit receives these digital signals for calculation, and the final result is then displayed through the display device, realizing accurate metering and statistics of electric energy, thereby completing the working process of the electric energy metering box.

[0011] Furthermore, the dust removal mechanism includes a dust removal box fixedly connected to the bottom of the inner wall of the box body. The front end of the dust removal box is movably connected to a first box cover. First slots are opened on both sides of the dust removal box. A first motor is fixedly connected to the rear end of the internal partition. The output end of the first motor is fixedly connected to a dust removal roller. A first synchronous wheel is fixedly connected to the front end of the outer wall of the dust removal roller. A synchronous belt is rotatably connected to the outer wall of the first synchronous wheel. The other end of the synchronous belt is rotatably connected to the inner wall of a second synchronous wheel. Two conveyor rollers are rotatably connected to the inner wall of the dust removal box. A first gear is fixedly connected to the outer wall of the other end of one of the conveyor rollers, and a second gear is fixedly connected to the rear end of the outer wall of the other conveyor roller. An air extraction pipe is fixedly connected to one side of the inner wall of the dust removal box. A blower is fixedly connected to one side of the air extraction pipe. An air outlet pipe is fixedly connected to the bottom of the blower. The outer wall of the dust-proof belt is movably connected to the two first slots. The inner wall of the second synchronous wheel is fixedly connected to one of the conveyor rollers. The first gear and the second gear are engaged, and both conveyor rollers are movably connected to the first box cover.

[0012] Through the above technical solution, during use, during the long-term operation of the electric energy metering box, external dust will invade the inside of the box body. The dust-proof belt is attached to the two internal partition boards to form a closed space for the internal structure, preventing dust from entering and interfering with the normal working process inside the electric energy metering box. After a long period of protection, the dust-removing mechanism is used to remove the dust on the dust-proof belt, so that the internal dust-removing effect can always be maintained stably. Specifically, the first motor at the rear end of the internal partition board is started to drive the dust-removing roller to rotate. Under the connection of the first synchronous pulley, the synchronous belt and the second synchronous pulley, one of the conveyor rollers can be driven to rotate. At the same time, under the meshing of the first gear and the second gear, the other conveyor roller rotates. The two conveyor rollers drive the dust-proof belt to be squeezed and transmitted in one direction, and the dust-proof belt rotates in one direction, so that the dust-proof belt can be completely dusted by the dust-removing roller. Subsequently, the fan is started to extract the removed dust. The air flow enters from the holes on the other side of the dust-removing box, and the removed and fallen dust enters from the air extraction pipe and then is discharged out of the box body from the air outlet pipe. Thus, the dust-removing process of the dust-proof belt ends, so that the dust accumulated on the dust-proof belt during long-term dust prevention can be removed, making the subsequent dust-proof effect stronger and the cleaning more convenient.

[0013] Furthermore, the fitting mechanism includes a second motor fixedly connected to the rear end of the box body. The output end of the second motor is fixedly connected with a first driving shaft. The outer wall of the first driving shaft is fixedly connected with a rotating block. Four corners of the rotating block are rotationally connected with connecting rods. A plurality of sliding grooves are opened inside the internal partition board. The other ends of the plurality of connecting rods are all rotationally connected with auxiliary rollers. A plurality of movable connection grooves are opened at the rear end of the auxiliary plate. The outer walls of the auxiliary rollers are respectively slidably connected with the corresponding sliding grooves. The plurality of movable connection grooves are respectively movably connected with the corresponding auxiliary rollers.

[0014] Through the above technical solution, during use, when the front cover plate is moved and then the dust-proof belt is placed on the two partition boards, the fitting mechanism is used to completely attach the dust-proof belt to the partition boards, preventing the dust-proof belt from warping and allowing dust to enter the box body, causing potential safety hazards inside. Specifically, first, the front cover plate is moved, and then the dust-proof belt is placed on the two partition boards and the front cover plate is closed. The second motor at the rear end of the box body is started to drive the rotating block on the outer wall of the first driving shaft, so that the plurality of connecting rods rotate in one direction. When the front cover plate is closed, the plurality of auxiliary rollers are kept inclined. Subsequently, under the rotation of the rotating block, the plurality of auxiliary rollers slide along the corresponding sliding grooves, so that the dust-proof belt can be pressed tightly along the partition board until the dust-proof belt can be completely attached, thereby the dust-proof belt can completely isolate external dust, greatly improving the dust-proof effect and reducing potential safety hazards.

[0015] Further, the tightening mechanism includes a tightening box fixedly connected to the top of the inner wall of the box body. The second box cover is fixedly connected to the rear end of the auxiliary plate. Two second notches are opened at the top of the tightening box. Two fixing blocks are fixedly connected to the rear end of the box body. One of the fixing blocks is fixedly connected to a third motor on one side. The output end of the third motor is fixedly connected to a reverse threaded rod. Two movable blocks are rotatably connected to the outer wall of the reverse threaded rod. The front ends of the two movable blocks are rotatably connected to movable rods. The other ends of the two movable rods are rotatably connected to a pressing roller. Two arc-shaped grooves are opened at the rear end of the tightening box. The rear end of the second box cover is movably connected to the tightening box. The dust-proof belt is slidably connected to the inside of the two second notches. The outer wall of the reverse threaded rod is rotatably connected to the two fixing blocks. The rear ends of the outer walls of the two pressing rollers are respectively movably connected to the corresponding arc-shaped grooves. The front ends of the two pressing rollers are both movably connected to the second box cover.

[0016] Through the above technical solution, during use, under the action of the fitting mechanism, it is possible to avoid gaps between the dust-proof belt and the partition board. Subsequently, the tightening mechanism is used to tighten the dust-proof belt, and an extra length of the dust-proof belt is tightened. The purpose is to prevent the dust-proof belt from breaking when taking the dust-proof belt, and it is more convenient during disassembly and installation. Specifically, start the third motor on one side of one of the fixing blocks to drive the reverse threaded rod to rotate. Subsequently, the two movable blocks will move towards the center on the reverse threaded rod. Then, under the support of the two movable rods, the two pressing rollers will rotate along the corresponding arc-shaped grooves. At this time, since the two pressing rollers are connected to the second box cover, as the rear end rotates, the dust-proof belt can be tightened along the rotation angle, so that the dust-proof belt can completely form a closed dust-proof space, making the dust-proof effect reach the highest level, and it can be quickly disassembled and installed when the dust-proof belt needs to be disassembled and installed. When replacing the dust-proof belt, the working process is opposite to the above. The whole process improves work efficiency and saves time.

[0017] The beneficial effects of the present invention are as follows: (1) By designing a metering component, a dust removal mechanism, a fitting mechanism, and a tightening mechanism, the electric energy metering box of the present invention can accurately measure and count electric energy, and ensure that the internal mechanism is not interfered by external dust after long-term operation, so as to ensure the normal operation of the internal metering components. In addition, after a long-term dust prevention process, the dust prevention part can be regularly dusted and the dust removal components can be replaced; (2) By designing a dust removal mechanism and a fitting mechanism, during the operation of the electric energy metering box of the present invention, the external dust can be prevented from entering the interior to interfere with the metering components through the dust prevention belt. The fitting mechanism is used to completely fit the dust removal belt inside the box body to achieve complete dust isolation. After a long-term isolation, the dust on the dust prevention belt is removed by the dust removal mechanism, thereby avoiding the accumulation of dust for a long time and reducing the isolation effect of the dust prevention belt. At the same time, under the overall protection of the dust prevention belt, it can effectively prevent dust and dissipate heat quickly, greatly improving the performance of the electric energy metering box; (3) By designing a tightening mechanism, during the long-term use of the electric energy metering box, the external dust is isolated on the dust prevention belt. The tightening mechanism can control the tightness of the dust prevention belt to complete the replacement of the dust prevention belt, avoiding dust falling on the internal components and causing component short circuits, thereby significantly improving the use safety of the electric energy metering box.

The metering integrated circuit 603 receives these digital signals for calculation, and the final result is then displayed through the display device 602 to achieve accurate metering and statistics of electric energy, thereby completing the working process of the electric energy metering box.

[0038] As Figures 6 - 9As shown in the figure, a secondary plate 7 is fixedly connected to the rear end of the front cover plate 2, a partition plate 8 is fixedly connected to the rear end of the secondary plate 7, another partition plate 8 is fixedly connected to the front end of the internal partition plate 5, a dust-proof belt 9 is movably connected to the outer wall of the partition plate 8, and a dust removal mechanism 10 is installed between the tops of the secondary plate 7 and the internal partition plate 5. The dust removal mechanism 10 includes a dust removal box 1001 fixedly connected to the bottom of the inner wall of the box body 1. A first box cover 1002 is movably connected to the front end of the dust removal box 1001. First notches 1003 are formed on both sides of the dust removal box 1001. A first motor 1004 is fixedly connected to the rear end of the internal partition plate 5. A dust removal roller 1005 is fixedly connected to the output end of the first motor 1004. A first synchronous pulley 1006 is fixedly connected to the front end of the outer wall of the dust removal roller 1005.

A second synchronous pulley 1008 is rotatably connected to the inner wall of the other end of the synchronous belt 1007. Two conveyor rollers 1009 are rotatably connected to the inner wall of the dust removal box 1001. A first gear 1010 is fixedly connected to the outer wall of the other end of one of the conveyor rollers 1009.

The inner wall of the second synchronous pulley 1008 is fixedly connected to one of the conveyor rollers 1009. The first gear 1010 and the second gear 1011 are meshed. Both conveyor rollers 1009 are movably connected to the first box cover 1002. When in use, during the long-term operation of the electric energy metering box, external dust will invade the inside of the box body 1. The dust-proof belt 9 is attached to the two internal partition plates 5 to form a closed space for the internal structure to prevent dust from entering and interfering with the normal working process inside the electric energy metering box. After a long-term protection, the dust removal mechanism 10 is used to remove the dust on the surface of the dust-proof belt 9, so that the internal dust removal effect can be kept stable all the time. Specifically, the first motor 1004 at the rear end of the internal partition plate 5 is started to drive the dust removal roller 1005 to rotate. Under the connection of the first synchronous pulley 1006, the synchronous belt 1007 and the second synchronous pulley 1008, one of the conveyor rollers 1009 can be driven to rotate. At the same time, under the meshing of the first gear 1010 and the second gear 1011, the other conveyor roller 1009 rotates. The two conveyor rollers 1009 drive the dust-proof belt 9 to be squeezed and transmitted in one direction, and the dust-proof belt 9 rotates in one direction, so that the dust-proof belt 9 can be completely dusted by the dust removal roller 1005.

So far, the dust removal process of the dust-proof belt 9 is completed, so that the dust accumulated on the dust-proof belt 9 during long-term dust prevention can be removed, making the subsequent dust-proof effect stronger.It is more convenient to clean at the same time.

[0039] As Figures 10 - 14 As shown, a fitting mechanism 11 is installed inside the box body 1. The fitting mechanism 11 includes a second motor 1101 fixedly connected to the rear end of the box body 1. The output end of the second motor 1101 is fixedly connected with a first driving shaft 1102. A rotating block 1103 is fixedly connected to the outer wall of the first driving shaft 1102. Connecting rods 1104 are rotatably connected to the four corners of the rotating block 1103. A plurality of sliding grooves 1105 are formed inside the internal partition plate 5. The other ends of the plurality of connecting rods 1104 are rotatably connected with auxiliary rollers 1106. A plurality of movable connection grooves 1107 are formed at the rear end of the auxiliary plate 7. The outer walls of the auxiliary rollers 1106 are respectively slidably connected with the corresponding sliding grooves 1105. The plurality of movable connection grooves 1107 are respectively movably connected with the corresponding auxiliary rollers 1106. When in use, after moving the front cover plate 2 and then placing the dust-proof belt 9 on the two partition plates 8, the fitting mechanism 11 is used to completely fit the dust-proof belt 9 on the partition plates 8 to prevent the dust-proof belt 9 from warping and allowing dust to enter the box body 1, causing potential safety hazards inside. Specifically, first move the front cover plate 2, then place the dust-proof belt 9 on the two partition plates 8 and cover the front cover plate 2. Start the second motor 1101 at the rear end of the box body 1 to drive the rotating block 1103 on the outer wall of the first driving shaft 1102, so that the plurality of connecting rods 1104 rotate in one direction. When the front cover plate 2 is closed, the plurality of auxiliary rollers 1106 are kept inclined. Then, under the rotation of the rotating block 1103, the plurality of auxiliary rollers 1106 slide along the corresponding sliding grooves 1105, enabling the dust-proof belt 9 to be pressed along the partition plates 8 until the dust-proof belt 9 can be completely fitted. Thus, the dust-proof belt 9 can completely isolate external dust, greatly improving the dust-proof effect and reducing potential safety hazards.

[0040] As Figures 15 - 17As shown in the figure, a tightening mechanism 12 is installed between the bottom of the auxiliary plate 7 and the inner partition 5. The tightening mechanism 12 includes a tightening box 1201 fixedly connected to the top of the inner wall of the box body 1. A second box cover 1202 is fixedly connected to the rear end of the auxiliary plate 7. Two second notches 1203 are opened at the top of the tightening box 1201. Two fixing blocks 1204 are fixedly connected to the rear end of the box body 1. A third motor 1205 is fixedly connected to one side of one of the fixing blocks 1204. The output end of the third motor 1205 is fixedly connected to a reverse threaded rod 1206. Two movable blocks 1207 are rotatably connected to the outer wall of the reverse threaded rod 1206. The front ends of the two movable blocks 1207 are rotatably connected to movable rods 1208. The other ends of the two movable rods 1208 are rotatably connected to a pressing roller 1209. Two arc-shaped grooves 1210 are opened at the rear end of the tightening box 1201. The rear end of the second box cover 1202 is movably connected to the tightening box 1201. The dust-proof belt 9 is slidably connected to the inside of the two second notches 1203. The outer wall of the reverse threaded rod 1206 is rotatably connected to the two fixing blocks 1204. The rear ends of the outer walls of the two pressing rollers 1209 are respectively movably connected to the corresponding arc-shaped grooves 1210. The front ends of the two pressing rollers 1209 are both movably connected to the second box cover 1202. When in use, under the action of the fitting mechanism 11, it is possible to prevent a gap between the dust-proof belt 9 and the partition plate 8. Subsequently, the tightening mechanism 12 is used to tighten the dust-proof belt 9, and an extra length of the dust-proof belt 9 is tightened. The purpose is to prevent the breakage of the dust-proof belt 9 when taking and holding the dust-proof belt 9, and it is more convenient during disassembly and installation. Specifically, the third motor 1205 on one side of one of the fixing blocks 1204 is started to drive the reverse threaded rod 1206 to rotate. Subsequently, the two movable blocks 1207 will move towards the center on the reverse threaded rod 1206. Subsequently, under the support of the two movable rods 1208, the two pressing rollers 1209 will rotate along the corresponding arc-shaped grooves 1210. At this time, since the two pressing rollers 1209 are connected to the second box cover 1202, as the rear end rotates, the dust-proof belt 9 can be tightened along the rotation angle, so that the dust-proof belt 9 can completely form a closed dust-proof space, making the dust-proof effect reach the highest level, and it can be quickly disassembled and installed when the dust-proof belt 9 needs to be disassembled and installed. When replacing the dust-proof belt 9, the working process is opposite to the above. The whole process improves the working efficiency and saves time.

[0041] The working principle of this embodiment is as follows. First, an external power supply is connected to the input circuit 601. Subsequently, the metering integrated circuit 603 connects the current transformer 604, the voltage transformer 605, and the display device 602, enabling the current transformer 604 and the voltage transformer 605 to collect current and voltage signals. After being processed by the signal processing circuit, digital signals are output. The metering integrated circuit 603 receives these digital signals for calculation, and the final result is then displayed through the display device 602. Subsequently, it can be directly observed through the cabinet door 3 or directly. The second motor 1101 at the rear end of the box body 1 is started to drive the rotating block 1103 on the outer wall of the first driving shaft 1102, causing the plurality of connecting rods 1104 to rotate in one direction. Subsequently, under the rotation of the rotating block 1103, the plurality of auxiliary rollers 1106 slide along the corresponding sliding grooves 1105, enabling the dust-proof belt 9 to be pressed tightly along the partition plate 8 until the dust-proof belt 9 can be completely adhered. Under the action of the fitting mechanism 11, then the third motor 1205 on one side of the fixing block 1204 is started to drive the reverse threaded rod 1206 to rotate. Subsequently, the two movable blocks 1207 will move towards the center on the reverse threaded rod 1206. Subsequently, under the support of the two movable rods 1208, the two pressing rollers 1209 will rotate along the corresponding arc-shaped grooves 1210, enabling the dust-proof belt 9 to be tightened along the rotation angle. Under the long-term dust-proof effect, it is necessary to remove dust from the dust-proof belt 9. The first motor 1004 at the rear end of the internal partition 5 is started to drive the dust removal roller 1005 to rotate. Under the connection of the first synchronous pulley 1006, the synchronous belt 1007, and the second synchronous pulley 1008, one of the conveyor rollers 1009 can be driven to rotate. At the same time, under the meshing of the first gear 1010 and the second gear 1011, the other conveyor roller 1009 rotates. The two conveyor rollers 1009 drive the dust-proof belt 9 to be squeezed and transmitted in one direction, rotating the dust-proof belt 9 in one direction, enabling the dust-proof belt 9 to be completely dusted by the dust removal roller 1005. Subsequently, the blower 1013 is started to extract the removed dust. The air flow enters from the holes on the other side of the dust removal box 1001, and the removed dust falls into the extraction duct 1012 and then is discharged outside the box body 1 from the air outlet duct 1014. Thus, the working process of the entire electric energy metering box is completed.

[0042] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
