Description

Technical Field

[0001] The present invention relates to the field of smart meters, and specifically to a smart meter. Background Art

[0002] A smart meter is one of the basic devices for data collection in a smart grid, undertaking the tasks of collecting, measuring, and transmitting original electrical energy data, and being the basis for realizing information integration, analysis and optimization, and information display. In addition to having the basic power consumption measurement function of a traditional electricity meter, it also has intelligent functions such as two-way multi-rate measurement function, user-side control function, two-way data communication function with multiple data transmission modes, and anti-stealing electricity function.

[0003] In order to facilitate power companies to read data, smart meters are often installed outdoors, which can reduce the possibility of electromagnetic interference and ensure the normal operation of the meters. The existing Chinese published patent document: CN117156830B discloses a smart meter for outdoor use, in which two wind-driven devices are simultaneously engaged with bevel gear three. At the same time, by engaging bevel gear five and bevel gear four, both ends of the transmission shaft are respectively connected to bevel gear five and the generator. In addition, the power input ends of two pressurizing mechanisms are simultaneously sleeved on the second rotating shaft, so that wind energy can be converted into electrical energy and mechanical energy. The electrical energy is stored in the storage battery, and the mechanical energy is used to drive the pressurizing device to pressurize the outside air into the meter box body for heat exchange; due to the setting of the refrigeration mechanism, the refrigeration mechanism consumes the stored electrical energy in a windless state, so as to minimize the input of external electrical energy when adjusting the internal temperature. However, the setting of the two ventilation channels can send air flow into the box body. Since the box body is outdoors, if it rains, rainwater is likely to enter the box body along with the air flow, resulting in the meter being damaged by moisture and short-circuited, lacking the function of preventing rainwater and having low safety.

[0031] The rain-proof mechanism includes an arc-shaped top plate 7 arranged on the top of the box body 1. Oblique plates 8 are fixedly installed at both ends of the arc-shaped top plate 7, so that rainwater is discharged through the arc-shaped top plate 7 and the oblique plates 8 to provide protection for the box body 1. Two symmetrically distributed rain-proof plates 9 are fixedly installed between the bottom of the arc-shaped top plate 7 and the outer side of the box body 1. Both ends of the rain-proof plate 9 are used for ventilation, so that air can enter the box body 1 through both ends of the rain-proof plate 9. An installation plug plate 10 is arranged between the two rain-proof plates 9. Sliding grooves for limiting and inserting the installation plug plate 10 are provided on the outer side of the rain-proof plate 9 and the top of the box body 1. A filter screen 11 is fixedly installed on the inner side of the installation plug plate 10 for filtering dust and impurities in the air. A top cylinder 12 is fixedly installed on the top of the arc-shaped top plate 7. Ring-shaped frames 13 are fixedly installed at both ends of the top cylinder 12. An installation rod 14 is rotatably installed between the two ring-shaped frames 13. Fans 15 are fixedly installed at both ends of the installation rod 14. The air flow outside the top cylinder 12 can drive the installation rod 14 to rotate through the fans 15. A driven rod 16 is rotatably installed between the inner side of the top cylinder 12 and the top of the box body 1. Conical wheels 17 that cooperate with each other are fixedly installed on the outer sides of the driven rod 16 and the installation rod 14, so that the installation rod 14 drives the driven rod 16 to rotate through the conical wheels 17. A protective box 33 is fixedly installed inside the top cylinder 12. Both conical wheels 17 are located inside the protective box 33.

A synchronous belt 18 is rotatably installed between the driven rod 16 and the two rotating rods 5, so that the driven rod 16 drives the exhaust fans 6 on the two rotating rods 5 to rotate through the synchronous belt 18, realizing the air circulation inside the box body 1;

[0032] When it rains, the arc-shaped top plate 7, the inclined plate 8 and the two rain shields 9 can provide protection for the top of the box body 1. Air can enter between the arc-shaped top plate 7 and the top of the box body 1 through the filter screen 11 on the installation insertion plate 10, so that the filter screen 11 filters dust and impurities in the air. The external air flow can drive the fan 15 to rotate, so that the fan 15 drives the installation rod 14 to rotate synchronously. The installation rod 14 drives the driven rod 16 to rotate through the two conical wheels 17, so that the driven rod 16 drives the two rotating rods 5 to rotate synchronously through the synchronous belt 18, so that the rotating rod 5 drives the exhaust fan 6 to rotate. One of the exhaust fans 6 sends the air between the arc-shaped top plate 7 and the box body 1 into the box body 1 to facilitate the heat dissipation of the electricity meter body 2, and discharges the air in the box body 1 through the other exhaust fan 6, realizing the air circulation in the box body 1, facilitating the removal of the heat in the box body 1, and ensuring that the electricity meter body 2 is in a dry environment, thus achieving the effect of safety protection.

[0033] The heat dissipation mechanism includes a water inlet box 19 fixedly installed at the bottom of the inclined plate 8. The top of the inclined plate 8 is fixedly installed with a water inlet filter plate 20. The size of the water inlet filter plate 20 is the same as the size of the top of the water inlet box 19, so that rainwater can enter the water inlet box 19 through the water inlet filter plate 20. The bottom of the water inlet box 19 is fixedly installed with a plurality of water inlet pipes 21 distributed at equal intervals. The water inlet pipes 21 extend into the interior of the box body 1. A first sealing plate 22 is fixedly installed between the five water inlet pipes 21. The first sealing plate 22 is fixedly installed on the outside of the box body 1. A second sealing plate 23 is fixedly installed between the bottom ends of the five water inlet pipes 21. The second sealing plate 23 is fixedly installed at the bottom of the box body 1, so that the water in the water inlet pipes 21 can be discharged from the bottom of the water inlet pipes 21. Both sides of the first sealing plate 22 and the second sealing plate 23 are made of rubber material to improve the sealing performance of the first sealing plate 22 and the second sealing plate 23 for the box body 1. Heat dissipation sticker plates 24 are arranged on both sides of the electricity meter body 2. The outside of the heat dissipation sticker plates 24 is in contact with the outside of the electricity meter body 2. Heat dissipation fins 25 are fixedly installed between the water inlet pipes 21 and the heat dissipation sticker plates 24, so that the heat dissipation sticker plates 24 and the heat dissipation fins 25 conduct the heat generated by the electricity meter body 2 into the water inlet pipes 21 and are discharged along with the water flow;

[0034] Rainwater can enter the water inlet box 19 through the water inlet filter plate 20 on the inclined plate 8, so that the water in the water inlet box 19 enters the water inlet pipes 21. The heat generated by the electricity meter body 2 can be conducted into the heat dissipation sticker plates 24, so that the heat enters the water inlet pipes 21 through the heat dissipation fins 25 and is discharged from the bottom of the water inlet pipes 21 along with the water flow in the water inlet pipes 21, realizing the rapid heat dissipation of the electricity meter body 2.

[0035] Working principle: The staff installs the meter body 2 in the box body 1 through two mounting plates 3. The external air flow can enter the top cylinder 12, causing the air flow to drive the fan 15 to rotate. The fan 15 drives the mounting rod 14 to rotate synchronously, so that the mounting rod 14 drives the driven rod 16 to rotate through two conical wheels 17. The driven rod 16 drives two rotating rods 5 to rotate synchronously through the synchronous belt 18. The rotating rods 5 drive the exhaust fans 6 to rotate in the mounting cylinder 4. One of the exhaust fans 6 conveys the air between the arc-shaped top plate 7 and the box body 1 into the box body 1, and the filter screen 11 on the mounting plug board 10 filters the dust in the air to prevent the air entering the box body 1 from causing dust adhesion on the surface of the meter body 2. The other exhaust fan 6 discharges the air in the box body 1 to keep the normal circulation of the air in the box body 1. The heat dissipation sticker plate 24 and the heat dissipation fin plate 25 absorb the heat generated by the meter body 2, so that the air flowing in the box body 1 quickly takes out the heat. When it is rainy outside, the rainwater enters the filter holes of the water inlet filter plate 20 through the arc-shaped top plate 7 and the inclined plate 8, so that the arc-shaped top plate 7, the inclined plate 8 and the rain shield 9 provide protection for the top of the box body 1 to prevent rainwater from entering the mounting cylinder 4. And the rainwater can enter the water inlet pipe 21 through the water inlet box 19. At the same time, the heat dissipation sticker plate 24 and the heat dissipation fin plate 25 can conduct the heat generated by the meter body 2 into the water inlet pipe 21, so that the heat is discharged from the bottom end of the water inlet pipe 21 along with the water in the water inlet pipe 21, thus achieving the effects of safety protection and rapid heat dissipation and ensuring the normal operation of the meter body 2 outdoors.

[0036] Embodiment 2: Please refer to Figures 2-8, This embodiment further elaborates on Example 1. The moisture-proof mechanism in the figure includes a first clamping frame 26 arranged at the bottom of the box body 1. A second clamping frame 27 is provided at the bottom of the first clamping frame 26. A slot for the first clamping frame 26 and the second clamping frame 27 to be limited and inserted is opened at the bottom of the box body 1. A rubber strip 28 is arranged between the first clamping frame 26 and the second clamping frame 27. A plurality of wire insertion holes are arranged at equal intervals on the surface of the rubber strip 28, so that the wire passes through the wire insertion holes and docks with the wiring ports on the electricity meter body 2. Utilizing the elasticity of the rubber strip 28, the sealing performance between the wire and the wire insertion hole is improved. A positioning rib 29 is fixedly installed on the outer side of the rubber strip 28. Positioning grooves for the positioning rib 29 to be limited and inserted are opened on the surfaces of the first clamping frame 26 and the second clamping frame 27 that are in contact with each other. The thickness of the positioning rib 29 is greater than the thickness of the rubber strip 28, so that when the first clamping frame 26 and the second clamping frame 27 are in contact, the positioning rib 29 can be clamped through the positioning groove. A plurality of U-shaped seats 30 are fixedly installed at equal intervals on the inner side of the first clamping frame 26. A pressing plate 31 is arranged inside the U-shaped seat 30. Both ends of the pressing plate 31 are butted against the inner side of the U-shaped seat 30 through coil springs, so that the pressing plate 31 is in contact with the wire insertion hole to seal the wire insertion hole. And when the wire is inserted into the wire insertion hole, the wire can push the pressing plate 31 to rotate. Ear plates 32 are fixedly installed on both sides of the second clamping frame 27. The ear plates 32 are butted against the inner side of the slot of the box body 1 through bolts, which is convenient for installing the second clamping frame 27 and for installing, disassembling and replacing the rubber strip 28.

[0037] In this embodiment: The staff can first insert the first clamping frame 26 into the slot in the box body 1, then insert the positioning rib 29 on the rubber strip 28 into the positioning groove of the first clamping frame 26. Then, the staff inserts the second clamping frame 27 into the slot in the box body 1, so that the positioning groove of the second clamping frame 27 clamps the bottom of the positioning rib 29, and the second clamping frame 27 is fixed to the bottom of the rubber strip 28 through bolts, so that the first clamping frame 26 and the second clamping frame 27 squeeze the rubber strip 28. When inserting the wire, the wire can be inserted into the wire insertion hole of the rubber strip 28, so that the outer side of the wire stretches the inner side of the wire insertion hole. Utilizing the elasticity of the rubber strip 28, the wire insertion hole adheres to the outer side of the wire. The outer side of the wire pushes the pressing plate 31 to rotate along the inner side of the U-shaped seat 30, so that the pressing plate 31 abuts against the outer side of the wire, and the wire can be docked with the wiring port of the electricity meter body 2. And the pressing plate 31 can provide sealing for the wire insertion holes without inserted wires, so that water vapor cannot enter the box body 1 through the wire insertion holes, keeping the inside of the box body 1 dry, thus achieving the effect of sealed wiring and improving the convenience of wire connection.

[0038] Example 3: Please refer to Figures 4-8, this embodiment further illustrates other embodiments. One end of the mounting plug plate 10 shown in the figure is fixedly installed with a magnet strip 34, and the rain shield 9 is made of metal. A pull block 35 is fixedly installed at one end of the mounting plug plate 10 away from the magnet strip 34, which is convenient for pulling out the mounting plug plate 10 between the two rain shields 9 to achieve cleaning and replacement of the filter screen 11. A plurality of equally distributed water receiving strips 36 are fixedly installed on the outer side of the water inlet filter plate 20. The outer side of the water receiving strip 36 is an arc-shaped structure, so that rainwater can pass through the water receiving strip 36 and enter the filter hole of the water inlet filter plate 20. A plurality of equally distributed partitions 37 are fixedly installed on the inner side of the clamping frame 1 26 and the inner side of the clamping frame 2 27. The partition 37 is located between two adjacent wire plug holes, which is convenient for inserting the wire into the corresponding wire plug hole and providing auxiliary pulling force for the rubber strip 28. A rubber block 38 is fixedly installed on the bottom of the pressing plate 31. The rubber block 38 contacts the wire plug hole on the rubber strip 28 to improve the sealing of the wire plug hole.

[0039] In this embodiment, the staff can pull the pull block 35 to drive the installation plug plate 10 to move along the slide grooves on the box body 1 and the rain shield 9, so that the installation plug plate 10 can be removed and the filter screen 11 on the installation plug plate 10 can be removed and cleaned. When the installation plug plate 10 is inserted into the slide grooves on the rain shield 9 and the box body 1, the magnet strip 34 is adsorbed in the slide groove of the rain shield 9, so that the installation plug plate 10 can be quickly installed, and the convenience of installation and removal of the installation plug plate 10 is improved. When rain falls, , can contact with the water receiving strip 36, can enter the filter hole of the water inlet filter plate 20 along the curved surface of the water receiving strip 36, provide guidance for rainwater, and facilitate the rapid filling of the water inlet box 19. The clamping frame 1 26 and the clamping frame 2 27 can provide auxiliary pressing to the rubber strip 28 through the partition 37, and separate each wire plug hole, so that the staff can insert the wire into the wire plug hole. The pressure plate 31 can press against the wire plug hole through the rubber block 38 to improve the sealing of the wire plug hole and prevent water vapor from entering the box body 1.
