Technical Field

[0001] The present invention relates to the technical field of electric meters, in particular to a multifunctional electric meter for smart grids. Background Art

[0002] As an electrical device used to measure the user's electricity consumption, the electric meter plays a vital role in modern society and facilitates the management of electricity consumption by relevant staff. Due to the importance of the electric meter itself and the existence of certain dangers, an electric auxiliary device for protecting the electric meter and protecting personal safety has emerged, namely the electric meter heat dissipation device.

[0003] There is also a patent in the prior art about a technical solution of a multifunctional electric meter for smart grids. For example, a Chinese patent with application number CN2018108277434 discloses a multifunctional electric meter, including: a power module, used to convert the three-phase voltage into the working voltage of the multifunctional electric meter; a voltage transformer, used to convert the signal of the three-phase voltage into a weak voltage signal; a current transformer, used to convert the primary current signal into a weak current signal; a metering chip, used to sample the weak voltage signal and the weak current signal in real time, and output metering parameters, including the effective value of the current and the active power; a micro control unit, connected to the metering chip, including: an electric work diagram generation module, used to generate initial electric work diagram data according to the effective value of the current and the active power; an electric work diagram compression module, used to compress the initial electric work diagram data using the electric work diagram compression method to generate compressed electric work diagram data; a communication module, connected to the micro control unit, used to send the compressed electric work diagram data;

[0004] In the above-mentioned prior art, a voltage transformer, a current transformer, an electric power diagram generation module and a micro control unit are set up; so that the application solves the contradiction between the high requirement of communication network bandwidth and the cost of setting up the communication network, and meets the production needs; but when the electric meter in the prior art is used for a long time, the temperature inside the electric meter body rises due to the long-term operation of the electronic components inside the electric meter body and direct sunlight. When the temperature inside the electric meter body rises, it will cause the braking flux of the electric energy meter, the voltage and current working flux amplitudes and the phase angle between them to change, thereby causing the basic error to change, which is called the temperature additional error, causing the electric meter to jump when in use and the problem of poor accuracy.

[0005] In view of this, the present invention proposes a multifunctional electric meter for smart grid to solve the above problems. Summary of the invention

[0006] In order to make up for the shortcomings of the prior art and solve the problem that the temperature inside the electric meter in the prior art rises due to the long-term operation of the electronic components inside the electric meter body and direct sunlight, the temperature inside the electric meter body rises, which will cause the braking flux of the electric energy meter, the voltage and current working flux amplitudes and the phase angle between them to change, thereby causing the basic error to change, called the temperature additional error, which causes the electric meter to jump when in use and has poor accuracy; the present invention proposes a multifunctional electric meter for smart grids.

The two ends of the No. 3 channel are respectively connected with the front end surface of the ventilation module and the side surface of one end away from the meter body, and the middle position of the No. 3 channel is connected with the end of the No. 2 channel away from the meter body; the air intake grille is fixedly connected to the two ends of the No. 3 channel, and the air intake grille is inclined, and the horizontal height of the end of the air intake grille close to the No. 2 channel is high; the No. 1 drainage piece is evenly arranged on the inner wall of the No. 3 channel close to the meter body, the No. 1 drainage piece is located at the opening of the No. 2 channel away from the meter body, and the No. 1 drainage piece is hinged to the inner wall of the No. 3 channel;

[0008] When in use, the electric meter is used in coastal areas with strong winds. The rear end face of the electric meter body is fixedly connected to the wall, channel No. 1 is opened in the electric meter body, and channel No. 1 is connected to the lower end face of the electric meter body. Ventilation modules are arranged on both sides of the electric meter body, and the ventilation modules do not affect the normal operation of the electric meter body. Channel No. 2 is evenly opened in the ventilation module, and one end of channel No. 2 is connected to channel No. 1. Channel No. 3 is evenly opened in the ventilation module, and channel No. 3 is arranged in an arc shape, and the two ends of channel No. 3 are respectively connected at the front end face of the ventilation module and the side face of the ventilation module away from the electric meter body. When the outside world is windy, the outside gas enters the inside of the ventilation module through the opening of channel No. 3, and then the gas flows out through the opening at the other end of the ventilation module. When the gas flows in channel No. 3, the airflow in channel No. 3 flows, the airflow in channel No. 1 flows into channel No. 2, the airflow in channel No. 2 flows into channel No. 3, and then flows out of the electric meter body through channel No. 3. When the gas enters channel No. 1 from the lower end of the electric meter body, the filter screen arranged at the lower side of channel No. 1 filters the incoming gas. , preventing external dust particles from entering the interior of the meter body with the gas, when the gas in channel No. 1 flows out through channel No. 2 and channel No. 3, the high-temperature gas inside the meter body flows out through channel No. 3, realizing ventilation of the gas inside the meter body, thereby keeping the airflow inside the meter body flowing to a certain extent, thereby achieving the effect of cooling the inside of the meter body, and the air intake grilles arranged at both ends of channel No. 3 are inclined, so that when it rains outside, the inclined setting of the air intake grilles prevents rainwater from entering the interior of the meter body through channel No. 3, and by arranging a No. 1 drainage piece in channel No. 3, the No. 1 drainage piece is hinged to the No. 3 channel, when the gas is blown from the front of the meter body, the No. 1 drainage piece is inclined toward the side of the ventilation module, and when the gas is blown from the side wall of the ventilation module, the No. 1 drainage piece is inclined toward the front end face of the meter body, and the No. 1 drainage piece is inclined to prevent the gas from entering the interior of the second channel from the No. 3 channel, resulting in the gas being unable to flow out from the No. 2 channel; thereby achieving cooling inside the meter body, thereby improving the use efficiency of the meter to a certain extent.

[0009] Preferably, both ends of each of the No. 3 channels are conical, and the internal aperture of the No. 3 channel is smaller than the apertures at the openings at both ends of the No. 3 channel;

[0010] When in use, the openings at both ends of channel No. 3 are set to be conical, and the internal aperture of channel No. 3 is made smaller than the aperture at the opening of channel No. 3. When the gas enters the interior of the ventilation module through channel No. 3, since the aperture at the opening of channel No. 3 is larger than the aperture inside channel No. 3, the gas converges at the opening of channel No. 3, and then flows into the interior of channel No. 3. Since the aperture inside channel No. 3 is small, according to the narrow tube effect, the flow rate of the gas increases when the gas flows inside channel No. 3, thereby increasing the exchange efficiency of the gas inside the meter body, thereby accelerating the flow of gas inside the meter body, and thereby achieving cooling inside the meter body.

[0011] Preferably, the first drainage piece is arranged in an arc shape, and a swing piece is arranged on the side of one end of the first drainage piece away from the opening of the second channel, the length of the swing piece is greater than the length of the first drainage piece, and the two ends of the swing piece are fixedly connected to the two ends of the first drainage piece, and the material of the swing piece is soft material and the surface of the swing piece is smooth;

[0012] When in use, the No. 1 drainage piece is set in an arc shape, and a swing piece is set at the end of the No. 1 drainage piece away from the No. 2 channel, the swing piece is made of soft material, and the surface of the swing piece is set smoothly. When the gas enters the ventilation module through the No. 3 channel, the No. 1 drainage piece is set in an arc shape, so that after the gas contacts the No. 1 drainage piece, the No. 1 drainage piece is set in an arc shape, and the drainage effect of the No. 1 drainage piece on the gas is enhanced. When the gas contacts the swing piece, the gas impacts the swing piece, and the swing piece swings. When the swing piece swings, the air flow velocity in the No. 3 channel is increased to a certain extent, and when the swing piece swings, dust in the gas is not easy to accumulate on the No. 1 drainage piece, thereby improving the ventilation efficiency in the No. 3 channel to a certain extent, and by making the two ends of the No. 3 channel conical, the gas flow velocity in the No. 3 channel is increased, and the swing efficiency of the swing piece is further increased, thereby improving the use efficiency of the electric meter.

[0013] Preferably, a No. 2 drainage piece is fixedly connected to the lower end surface of the electric meter body, and the No. 2 drainage piece is arc-shaped; the No. 2 drainage piece is used to introduce gas into the No. 1 channel;

[0014] When in use, a No. 2 drain piece is arranged on the lower end face of the electric meter body, and the No. 2 drain piece is arranged in an arc shape. When gas is blown from the front end face of the electric meter body, the gas enters the No. 3 channel, and the No. 3 channel exhausts air from the No. 2 channel and the No. 1 channel. The No. 1 channel exhausts air from the lower end of the electric meter body, and through the No. 2 drain piece, when the gas is blown toward the front end face of the electric meter body, the No. 2 drain piece is arranged in an arc shape, and the No. 2 drain piece has a drainage effect on the gas, so that the gas enters the No. 1 channel, and the flow rate of the gas in the No. 1 channel is increased. When the No. 3 channel is exhausted, the flow rate of the gas in the No. 1 channel when flowing to the No. 2 channel is increased, thereby increasing the gas flow rate inside the electric meter body, thereby improving the use efficiency of the electric meter to a certain extent.

[0015] Preferably, the transverse middle position of the second drainage piece is fixedly connected to a first block, and the left and right sides of the first block are both arranged in a concave arc shape; the first block is used to introduce gas into the first channel;

[0016] When in use, block No. 1 is set in the horizontal middle position of drain plate No. 2, so that the left and right sides of block No. 1 are set in a concave arc shape. When gas is blown from the left and right sides of the meter body, the gas enters channel No. 3 through the left and right sides of the ventilation module, and then the gas flows out from the front end face of the meter body. When the gas is blown at the lower end of the meter body, the gas contacts the left and right sides of block No. 1, and the concave arcs on the left and right sides of block No. 1 drain the gas and guide the gas into channel No. 1, thereby increasing the gas flow rate in channel No. 1. When channel No. 3 draws air from channel No. 2 and channel No. 1, block No. 1 increases the gas flow rate in channel No. 1, thereby increasing the flow rate of the meter body, thereby increasing the gas exchange rate of the meter body, and thus improving the cooling efficiency inside the meter body.

[0017] Preferably, water-absorbing pads are laid on the upper and lower sides of the air intake grille, the material of the water-absorbing pads is silica gel, and a number 1 hole is evenly opened on the water-absorbing pads;

[0018] When in use, water-absorbing pads are evenly laid on the lower side of the air intake grille, and the material of the water-absorbing pads is silica gel. When the gas enters the No. 3 channel through the opening of the No. 3 channel, the gas contacts the water-absorbing pads, and the water-absorbing pads absorb the moisture in the gas, so that when the gas enters the No. 3 channel, the moisture in the gas is reduced, thereby avoiding moisture in the electric meter body to a certain extent, and by slanting the air intake grille, when the gas contacts the air intake grille, the impact force of the gas on the air intake grille is increased, so that the moisture in the gas is further absorbed by the water-absorbing pad, and by opening a No. 1 hole on the water-absorbing pad, the contact area between the water-absorbing pad and the gas is increased, and the gap between the water-absorbing pads on the surface of the air intake grille will not affect the wind flow rate, so that the moisture in the gas is further absorbed by the water-absorbing pad, thereby improving the use efficiency of the electric meter.

[0032] like Figures 1 to 7 As shown, a multifunctional electric meter for smart grid includes an electric meter body 1, a No. 1 channel 11 and a ventilation module 2, wherein the No. 1 channel 11 is vertically opened inside the electric meter body 1, the lower end of the No. 1 channel 11 is communicated with the lower end surface of the electric meter body 1, and the lower inner wall of the No. 1 channel 11 is fixedly connected with a filter screen 12; the ventilation module 2 is fixedly connected to both sides of the electric meter body 1, and the ventilation module 2 includes a No. 2 channel 21, a No. 3 channel 22, an air intake grille 23 and a No. 1 guide plate 24; the No. 2 channel 21 is evenly opened inside the ventilation module 2, one end of the No. 2 channel 21 is communicated with the No. 1 channel 11, and the angle between the No. 2 channel 21 and the No. 1 channel 11 is 45 degrees; the No. 3 channel 22 is evenly connected to the No. 2 channel 21, and the No. 1 channel 11 is connected to the No. 1 channel 11. The third channel 22 is evenly arranged inside the ventilation module 2, and the third channel 22 is arranged in an arc shape. The two ends of the third channel 22 are respectively connected to the front end surface of the ventilation module 2 and the side surface of one end away from the electric meter body 1, and the middle position of the third channel 22 is connected to the end of the second channel 21 away from the electric meter body 1; the air intake grille 23 is fixedly connected to the two ends of the third channel 22, and the air intake grille 23 is inclined, and the horizontal height of the end of the air intake grille 23 close to the second channel 21 is high; the first drain piece 24 is evenly arranged on the inner wall of the third channel 22 close to the electric meter body 1, the first drain piece 24 is located at the opening of the second channel 21 away from the electric meter body 1, and the first drain piece 24 is hinged to the inner wall of the third channel 22;

[0033] When in use, the electric meter is used in coastal areas with strong winds. The rear end face of the electric meter body 1 is fixedly connected to the wall, a No. 1 channel 11 is opened in the electric meter body 1, and the No. 1 channel 11 is communicated with the lower end face of the electric meter body 1. Ventilation modules 2 are arranged on both sides of the electric meter body 1, and the ventilation modules 2 do not affect the normal operation of the electric meter body 1. A No. 2 channel 21 is evenly opened in the ventilation module 2, and one end of the No. 2 channel 21 is communicated with the No. 1 channel 11. A No. 3 channel 22 is evenly opened in the ventilation module 2, and the No. 3 channel 22 is arranged in an arc shape, and the two ends of the No. 3 channel 22 are respectively at the front end of the ventilation module 2. The surface is connected with the side of one end of the ventilation module 2 away from the electric meter body 1. When the outside is windy, the outside gas enters the ventilation module 2 through the opening of the third channel 22, and then the gas flows out through the opening at the other end of the ventilation module 2. When the gas flows in the third channel 22, the airflow in the third channel 22 flows, the airflow in the first channel 11 flows into the second channel 21, the airflow in the second channel 21 flows into the third channel 22, and then flows out of the electric meter body 1 through the third channel 22. When the gas enters the first channel 11 from the lower end of the electric meter body 1, the filter 12 set at the lower side of the first channel 11 filters the incoming gas. The air in the first channel 11 is filtered to prevent dust particles from entering the electric meter body 1 along with the gas. When the gas in the first channel 11 flows out through the second channel 21 and the third channel 22, the high-temperature gas in the electric meter body 1 flows out through the third channel 22, so that the gas in the electric meter body 1 is ventilated, so that the air flow in the electric meter body 1 is kept flowing to a certain extent, thereby achieving the effect of cooling the inside of the electric meter body 1. The air intake grilles 23 arranged at both ends of the third channel 22 are inclined, so that when it rains outside, the air intake grilles 23 are inclined to prevent rainwater from entering the electric meter body 1 through the third channel 22. The interior of the electric meter body 1 is provided with a drain piece 24 in the No. 3 channel 22, so that the drain piece 24 is hinged with the No. 3 channel 22. When the gas is blown from the front of the electric meter body 1, the drain piece 24 is inclined toward the side of the ventilation module 2. When the gas is blown from the side wall of the ventilation module 2, the drain piece 24 is inclined toward the front end face of the electric meter body 1. The inclined setting of the drain piece 24 prevents the gas from entering the interior of the No. 2 channel 21 from the No. 3 channel 22, resulting in the gas being unable to flow out of the No. 2 channel 21; thereby achieving cooling inside the electric meter body 1, thereby improving the use efficiency of the electric meter to a certain extent.

[0034] As a specific implementation of the present invention, both ends of each of the No. 3 channels 22 are conical, and the internal aperture of the No. 3 channel 22 is smaller than the apertures at the openings at both ends of the No. 3 channel 22;

[0035] When in use, the openings at both ends of channel No. 3 22 are set to be conical, and the internal aperture of channel No. 3 22 is smaller than the aperture at the opening of channel No. 3 22. When the gas enters the interior of the ventilation module 2 through channel No. 3 22, since the aperture at the opening of channel No. 3 22 is larger than the aperture inside channel No. 3 22, the gas converges at the opening of channel No. 3 22, and then flows into the interior of channel No. 3 22. Since the aperture inside channel No. 3 22 is small, according to the narrow tube effect, when the gas flows inside channel No. 3 22, the flow rate of the gas increases, thereby increasing the exchange efficiency of the gas inside the meter body 1, thereby accelerating the flow of gas inside the meter body 1, and thereby achieving cooling inside the meter body 1.

[0036] As a specific embodiment of the present invention, the first drainage piece 24 is arranged in an arc shape, and a swing piece 25 is arranged on the side of one end of the first drainage piece 24 away from the opening of the second channel 21, the length of the swing piece 25 is greater than the length of the first drainage piece 24, and the two ends of the swing piece 25 are fixedly connected to the two ends of the first drainage piece 24, and the material of the swing piece 25 is soft material and the surface of the swing piece 25 is smooth;

[0037] When in use, the No. 1 drainage piece 24 is set in an arc shape, and a swing piece 25 is set at the end of the No. 1 drainage piece 24 away from the No. 2 channel 21, and the swing piece 25 is made of soft material, and the surface of the swing piece 25 is set smoothly. When the gas enters the interior of the ventilation module 2 through the No. 3 channel 22, the No. 1 drainage piece 24 is set in an arc shape, so that after the gas contacts the No. 1 drainage piece 24, the No. 1 drainage piece 24 is set in an arc shape, and the drainage effect of the No. 1 drainage piece 24 on the gas is enhanced, and when the gas contacts the swing piece 25, the gas The swing piece 25 impacts and swings. When the swing piece 25 swings, the air flow velocity in the No. 3 channel 22 increases to a certain extent. When the swing piece 25 swings, the dust in the gas is not easy to accumulate on the No. 1 drain piece 24, thereby improving the ventilation efficiency in the No. 3 channel 22 to a certain extent. By making the two ends of the No. 3 channel 22 conical, the gas flow velocity in the No. 3 channel 22 is increased, and the swing efficiency of the swing piece 25 is further increased, thereby improving the use efficiency of the electric meter.

[0038] As a specific embodiment of the present invention, the lower end surface of the electric meter body 1 is fixedly connected with a second drain piece 13, and the second drain piece 13 is arc-shaped; the second drain piece 13 is used to introduce gas into the first channel 11;

[0039] When in use, by setting a No. 2 drain piece 13 on the lower end face of the meter body 1, the No. 2 drain piece 13 is set in an arc shape. When the gas is blown from the front end face of the meter body 1, the gas enters the No. 3 channel 22, and the No. 3 channel 22 is exhausted from the No. 2 channel 21 and the No. 1 channel 11. The No. 1 channel 11 is exhausted from the lower end of the meter body 1, and through the No. 2 drain piece 13, when the gas is blown against the front end face of the meter body 1, the No. 2 drain piece 13 is set in an arc shape, and the No. 2 drain piece 13 has a drainage effect on the gas, so that the gas enters the No. 1 channel 11, and the flow rate of the gas in the No. 1 channel 11 is increased. When the No. 3 channel 22 is exhausted, the flow rate of the gas in the No. 1 channel 11 when flowing to the No. 2 channel 21 increases, thereby increasing the gas flow rate inside the meter body 1, thereby improving the use efficiency of the meter to a certain extent.

[0040] As a specific embodiment of the present invention, the second guide plate 13 is fixedly connected to a first block 14 in the middle of the horizontal direction, and the left and right sides of the first block 14 are both concave arc-shaped; the first block 14 is used to introduce gas into the first channel 11;

[0041] When in use, block No. 14 is set in the horizontal middle position of drain plate No. 2, so that the left and right sides of block No. 14 are concave arc-shaped. When the gas is blown from the left and right sides of the meter body 1, the gas enters channel No. 3 22 through the left and right sides of the ventilation module 2, and then the gas flows out from the front end face of the meter body 1. When the gas is blown at the lower end of the meter body 1, the gas contacts the left and right sides of block No. 14. The concave arcs on the left and right sides of block No. 14 drain the gas and guide the gas into channel No. 11, so that the gas flow rate in channel No. 11 is increased. When channel No. 3 22 draws air from channel No. 21 and channel No. 1 11, block No. 14 increases the gas flow rate in channel No. 1 11, thereby increasing the flow rate of the meter body 1, thereby increasing the gas exchange speed of the meter body 1, thereby improving the cooling efficiency inside the meter body 1.

[0042] As a specific embodiment of the present invention, the upper and lower sides of the air intake grille 23 are both paved with water absorbent pads 26, the material of the water absorbent pads 26 is silica gel material, and the water absorbent pads 26 are evenly provided with number 1 holes;

[0043] When in use, water-absorbing pads 26 are evenly laid on the lower side of the air intake grille 23, and the material of the water-absorbing pads 26 is silica gel. When the gas enters the No. 3 channel 22 through the opening of the No. 3 channel 22, the gas contacts the water-absorbing pads 26, and the water-absorbing pads 26 absorb the moisture in the gas, so that when the gas enters the No. 3 channel 22, the moisture in the gas is reduced, thereby avoiding moisture in the electric meter body 1 to a certain extent, and by tilting the air intake grille 23, when the gas contacts the air intake grille 23, the impact force of the gas on the air intake grille 23 is increased, so that the moisture in the gas is further absorbed by the water-absorbing pads 26, and by opening a No. 1 hole on the water-absorbing pads 26, the contact area between the water-absorbing pads 26 and the gas is increased, and the gaps between the water-absorbing pads 26 on the surface of the air intake grille 23 will not affect the wind flow rate, and the moisture in the gas is further absorbed by the water-absorbing pads 26, thereby improving the use efficiency of the electric meter.

The block 2 is connected to the side of one end away from the meter body 1. When the outside world is windy, the outside gas enters the inside of the ventilation module 2 through the opening of the No. 3 channel 22, and then the gas flows out through the opening at the other end of the ventilation module 2. When the gas flows in the No. 3 channel 22, the airflow flows in the No. 3 channel 22, and a negative pressure is generated in the No. 3 channel 22, so that the airflow is exhausted from the No. 2 channel 21, and the No. 2 channel 21 is exhausted from the No. 1 channel 11. The airflow in the No. 1 channel 11 flows into the No. 2 channel 21, and the No. 1 channel 11 is exhausted from the lower end of the meter body 1 through the lower end opening. When the gas enters the No. 1 channel 11, The filter 12 arranged at the lower side of the No. 1 channel 11 filters the incoming gas to prevent external dust particles from entering the inside of the electric meter body 1 along with the gas. When the gas in the No. 1 channel 11 flows out through the No. 2 channel 21 and the No. 3 channel 22, the high-temperature gas inside the electric meter body 1 flows out through the No. 3 channel 22, thereby realizing the ventilation of the gas inside the electric meter body 1, thereby keeping the air flow inside the electric meter body 1 flowing to a certain extent, thereby achieving the effect of cooling the inside of the electric meter body 1, and the air intake grilles 23 arranged at both ends of the No. 3 channel 22 are arranged tilted, so that when it rains outside, the air intake grilles 23 are tilted. The arrangement prevents rainwater from entering the interior of the meter body 1 through the No. 3 channel 22, and by arranging the No. 1 drain piece 24 in the No. 3 channel 22, the No. 1 drain piece 24 is hinged to the No. 3 channel 22. When the gas is blown from the front of the meter body 1, the No. 1 drain piece 24 is inclined toward the side of the ventilation module 2. When the gas is blown from the side wall of the ventilation module 2, the No. 1 drain piece 24 is inclined toward the front end face of the meter body 1. The inclination of the No. 1 drain piece 24 prevents the gas from entering the interior of the No. 2 channel 21 when flowing, thereby keeping the internal temperature of the meter body 1 stable, thereby improving the use efficiency of the meter to a certain extent.
