Description

Technical Field

[0001] The invention relates to the technical field of electric energy metering boxes, and in particular to an electric energy metering box based on an aluminum alloy material with excellent mechanical properties. Background Art

[0002] With the advancement of smart grid construction, the thermal management of the electronic components inside the energy meter box, as a key metering device in the power system, has become an important factor affecting the reliability of the equipment. In the existing design of the energy meter box, in order to effectively reduce the operating temperature of the internal electronic components, heat dissipation holes are usually opened on its side walls. These heat dissipation holes can significantly improve air circulation, thereby enhancing the heat dissipation effect and ensuring that the electronic components maintain a suitable operating temperature during high-load operation. However, this design has the following significant problems in practical applications: 1. Water vapor intrusion problem: Impact of rainy days or humid environments: On rainy days or in humid environments, the heat dissipation holes opened easily cause a large amount of water vapor to enter the power meter box. Since the power meter box is usually installed outdoors or in a semi-open environment, a large amount of water vapor will enter the power meter box through the heat dissipation holes and stay there for a long time. The retained water vapor adheres to the surface of electronic components for a long time, which will cause their insulation performance to deteriorate, and even cause serious faults such as short circuits and leakage.

[0003] 2. Dust accumulation problem: Dust adhesion after the weather returns to normal: After the weather returns to normal, a lot of dust will float in the air. At this time, the water vapor attached to the electronic components will further capture the dust in the air, forming a layer of dust film. This layer of dust film not only affects the appearance of the electronic components, but also hinders the effective dissipation of heat, causing the temperature of the electronic components to rise, further increasing the risk of overheating and damage to the equipment.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1: An electric energy meter box based on an aluminum alloy material with excellent mechanical properties, referring to Figure 1-Figure 5 As shown, it includes: a cabinet 1, which is provided with a plurality of heat dissipation holes; a fixed seat 2, which is installed on the cabinet 1; a cabinet door 3, which is rotatably arranged on the cabinet 1; a heat conductor 4, which is fixed in the cabinet 1, and the heat conductor 4 is used to install electronic components; a first sliding frame 6, which is slidably arranged in the cabinet 1, and a plurality of through holes are arranged on the first sliding frame 6, and the first sliding frame 6 is used to make the through holes on it intersect with the heat dissipation holes on the cabinet 1 in rainy days; a driving unit, which is arranged on the cabinet 1, and the driving unit is used to change the position of the first sliding frame 6 according to the external rainfall; the cabinet 1 is provided with a step surface 101, and the cabinet door 3 is provided with a bending surface 301, and the bending surface 301 is in contact with the step surface 101 in the closed state, so as to improve the sealing between the cabinet 1 and the cabinet door 3; the fixed seat 2 is provided with evenly distributed grooves, and the grooves of the fixed seat 2 are used for airflow to pass through.

[0029] In the above scheme, the cabinet door 3 is in contact with the cabinet body 1 to form a complete protective structure. The cabinet body 1 and the cabinet door 3 are both made of insulating materials, and the cabinet body 1 and the cabinet door 3 are embedded with aluminum alloy frames to improve their strength. A plurality of arc plates are arranged on the cabinet body 1, and the arc plates are directly opposite to the adjacent heat dissipation holes on the cabinet body 1 to prevent rainwater from passing through the heat dissipation holes on the cabinet body 1. External air passes through the grooves of the fixing seat 2 to dissipate heat to the back of the electronic components installed on the heat conducting member 4, thereby improving the heat dissipation effect of the electronic components and avoiding uneven heat distribution on the electronic components. A sealing strip is arranged on the bending surface 301, and the bending surface 301 contacts the step surface 101, so that the contact point between the cabinet body 1 and the cabinet door 3 is a folded surface, thereby improving the sealing of the two in time and preventing rainwater from entering the cabinet body 1 on rainy days. In the initial state, the through holes on the first sliding frame 6 are connected to the heat dissipation holes on the cabinet body 1.

[0030] Reference Figure 2-Figure 4 As shown, the driving unit includes: a sliding shell 7, which is slidably arranged on the side wall of the cabinet 1, and the sliding shell 7 is provided with a drainage hole; a fixed frame 8, which is fixed in the cabinet 1, the sliding shell 7 is slidably connected to the fixed frame 8, and a spring is installed between the sliding shell 7 and the fixed frame 8.

[0031] In the above scheme, the drainage hole on the sliding shell 7 is relatively small, so as to slowly drain the rainwater accumulated therein, slow down the opening time of the first sliding frame 6 after the rain stops, and connect the inner wall of the cabinet 1 with the outside world after the water vapor content in the air decreases.

[0032] Reference Figure 3 and Figure 5 As shown, a plurality of shells 9 are fixedly connected to the inner wall of the cabinet 1, the first sliding frame 6 penetrates the shell 9 and is slidably connected thereto, the shell 9 covers the heat dissipation holes on the cabinet 1, and the shell 9 is provided with evenly distributed inclined holes and vertically arranged drainage channels, and adjacent shells 9 are connected through the drainage channels, and the drainage channel of the lowermost shell 9 penetrates the cabinet 1 to circulate with the outside.

[0033] In the above scheme, the inclined holes on the left shell body 9 are inclined upward from left to right, the shell bodies 9 on the left and right sides of the cabinet body 1 are symmetrically distributed, and the inclined holes on the shell body 9 and the heat dissipation holes on the cabinet body 1 are staggered. The liquid splashing through the heat dissipation holes on the cabinet body 1 is secondary intercepted in the shell body 9 to further prevent the liquid from entering the cabinet body 1.

[0034] Specific working principle: When using this device, the operator first opens the cabinet door 3 and installs a specified number of electronic components on the heat conductor 4, then closes the cabinet door 3 and makes the fixing base 2 fit the wall, and fixes the fixing base 2 in the specified position by bolts, even if the cabinet 1 is hung in a specified area on the wall. Subsequently, the electronic components can be connected to the corresponding circuits to complete the installation and use of this device.

[0035] During the use of the device, if there is wind outside, the flowing air enters the cabinet 1 through the heat dissipation holes, the through holes of the first sliding frame 6 and the inclined holes of the shell 9, and the subsequent gas is discharged through the inclined holes of the shell 9 on the other side, the through holes of the first sliding frame 6 and the heat dissipation holes on the cabinet 1. The flowing gas takes away the heat generated by the electronic components, thereby achieving the effect of heat dissipation and cooling the electronic components. At the same time, the flowing gas passes through the outer surface of the cabinet 1 and the groove of the fixed seat 2 to dissipate heat and cool the cabinet 1. The heat generated by the electronic components is transferred to the outside through the cabinet 1, and the electronic components are indirectly cooled, ensuring that the electronic components work at a suitable temperature, that is, extending their service life.

[0036] If it rains outside, rainwater accumulates in the sliding shell 7, causing the sliding shell 7 to drive the first sliding frame 6 to move downward. The sliding shell 7 compresses the connected spring at the same time, and the first sliding frame 6 moves downward, so that the through holes on it are staggered with the heat dissipation holes on the cabinet 1, thereby reducing the amount of water vapor entering the cabinet 1 and protecting the normal operation of the electronic components in the cabinet 1. After the rain stops, the rainwater accumulated in the sliding shell 7 is gradually discharged, causing the sliding shell 7 to drive the first sliding frame 6 to move in the opposite direction and reset, and then the external air and the air in the cabinet 1 are exchanged for heat dissipation.

[0037] When the device is repaired and maintained, the operator opens the cabinet door 3 to inspect and repair the electronic components. After the repair is completed, the operator closes the cabinet door 3 again.

[0038] Example 2: Based on Example 1, refer to Figure 6 and Figure 7 As shown, it also includes: a second sliding frame 11, which is slidably arranged on the top of the cabinet 1, and a tension spring is installed between the cabinet 1, the upper surface of the second sliding frame 11 is lower than the upper surface of the cabinet 1, and the side wall of the cabinet 1 is provided with a circular hole, and the circular hole of the cabinet 1 is located on the upper side of the second sliding frame 11; a telescopic push rod 12, which is installed on the cabinet 1, and the sliding shell 7 and the fixed frame 8 form a cavity, and the cavity formed by the sliding shell 7 and the fixed frame 8 is connected with the cavity of the telescopic push rod 12 through a pipeline, and the cavity, pipeline and cavity of the telescopic push rod 12 are filled with liquid, and the telescopic end of the telescopic push rod 12 is in contact with the second sliding frame 11, which is used to limit the movement of the second sliding frame 11 when it is not rainy.

[0039] In the above scheme, the second sliding frame 11 is composed of a rectangular plate and a U-shaped frame, and the telescopic end of the telescopic push rod 12 is U-shaped. In the initial state, the telescopic end of the telescopic push rod 12 is in a retracted state, and the telescopic end of the telescopic push rod 12 contacts the lower surface of the U-shaped frame on the second sliding frame 11. At this time, the telescopic end of the telescopic push rod 12 limits the downward movement of the second sliding frame 11.

[0040] Reference Figure 6 and Figure 8 As shown, the second sliding frame 11 is fixedly connected to the first fixed shell 13, the heat conductive member 4 is provided with a liquid flow channel, the first fixed shell 13 is used to be inserted into the liquid flow channel of the heat conductive member 4, the second sliding frame 11 is provided with a through hole, the first fixed shell 13 is slidably provided with a sliding plug 14, and a spring is installed between the first fixed shell 13 and the sliding plug 14, the sliding plug 14 is used to block the through hole on the second sliding frame 11, and a limiting block 15 is fixedly connected in the liquid flow channel of the heat conductive member 4, and the limiting block 15 is used to squeeze the sliding plug 14.

[0041] In the above solution, in the initial state, the sliding plug 14 is in a state of blocking the through hole on the second sliding frame 11 , and a sealing ring is provided on the outer surface of the first fixed shell 13 to improve the sealing between the first fixed shell 13 and the heat conducting member 4 .

[0042] Specific working principle: during the use of the device, if it rains, rainwater accumulates in the sliding shell 7 and on the upper surface of the second sliding frame 11. During the accumulation process, part of the rainwater is discharged from the drainage hole on the sliding shell 7, and part of the rainwater on the upper surface of the second sliding frame 11 is discharged through the circular hole on the cabinet 1. At this time, restricted by the telescopic end of the telescopic push rod 12, the second sliding frame 11 remains stationary first. When rainwater continues to accumulate in the sliding shell 7 until the above-mentioned downward movement operation is repeated, the sliding shell 7 moves downward and squeezes the liquid in the fixed frame 8 into the chamber of the telescopic push rod 12 through the conduit, so that the telescopic end of the telescopic push rod 12 extends out, and the telescopic end of the telescopic push rod 12 releases the limit on the second sliding frame 11. Subsequently, the rainwater accumulated on the upper surface of the second sliding frame 11 squeezes the second sliding frame 11 to move downward, and the second sliding frame 11 moves downward to stretch the tension spring connected thereto, and at this time, the U-shaped frame of the second sliding frame 11 contacts the end of the telescopic push rod 12, and the U-shaped frame of the second sliding frame 11 restricts the telescopic end of the telescopic push rod 12 from retracting.

[0043] During the downward movement of the second sliding frame 11, the second sliding frame 11 drives the first fixed shell 13 to move downward and insert into the liquid flow channel of the heat conductive member 4. Subsequently, the second sliding frame 11 and the first fixed shell 13 continue to move downward so that the sliding plug 14 contacts the limit block 15. Under the limiting action of the limit block 15, the sliding plug 14 stops moving. Subsequently, rainwater continues to accumulate, and the second sliding frame 11 and the first fixed shell 13 continue to move downward. The spring connected to the sliding plug 14 is compressed, and the sliding plug 14 releases the blockage of the through hole on the second sliding frame 11. At this time, the rainwater on the upper surface of the second sliding frame 11 passes through the first fixed shell 13 and the liquid flow channel of the heat conductive member 4, and the rainwater quickly cools down the electronic components thereon through the heat conductive member 4, thereby avoiding excessive temperature of the electronic components in a closed state and extending the service life of the electronic components.

[0044] Example 3: Based on Example 2, refer to Figure 6 and Fig. 9 As shown, it also includes: a protective shell 16, which is fixedly connected to the cabinet 1; a first rotating shaft 17, which penetrates the protective shell 16 and the cabinet 1 and is rotatably connected to the two, and an impeller 18 is fixedly connected to one end of the first rotating shaft 17 located outside the cabinet 1, and a fan 19 is fixedly connected to the other end of the first rotating shaft 17.

[0045] Specific working principle: During the use of this device, when the wind blows outside, the air flow blows the impeller 18 to rotate, and the impeller 18 drives the fan 19 to rotate through the first rotating shaft 17. The rotation of the fan 19 stirs the air in the cabinet 1, so that the temperature in the cabinet 1 remains relatively uniform, thereby facilitating the temperature of the electronic components in the cabinet 1 to remain relatively consistent, thereby extending the service life of the device.

[0046] Example 4: Based on Example 3, refer to Fig. 9 and Fig.10As shown, it also includes: a second rotating shaft 20, which is rotatably set on the protective shell 16 and is transmitted to the first rotating shaft 17 through a bevel gear set; a second fixed shell 21, which is fixedly connected to the protective shell 16, and the second fixed shell 21 is rotatably set with a third rotating shaft 211 through a one-way bearing, and the facing ends of the third rotating shaft 211 and the second rotating shaft 20 are both provided with magnets, and the axial magnetic pulling force generated by the magnet assembly between the third rotating shaft 211 and the second rotating shaft 20 realizes non-contact torque transmission; a fourth rotating shaft 22, which is slidably set in the second fixed shell 21, and a coil spring is set between the fourth rotating shaft 22 and the third rotating shaft 211; a hammer member 23, which is fixedly connected to the fourth rotating shaft 22; a fixing member 24, which is fixedly connected to the protective shell 16, and the hammer member 23 is used to knock the fixing member 24 to make a sound.

[0047] In the above scheme, the transmission ratio of the bevel gear set between the second rotating shaft 20 and the first rotating shaft 17 is set according to demand. When the wind force in the area is relatively small, the bevel gear set can be changed into a reduction gear set to facilitate the effective storage of power in the device. The hammer member 23 is composed of a circular ring and three elastic rods, and an iron ball is arranged at the end of the elastic rod.

[0048] Reference Fig. 9 and Fig.10 As shown, the fourth rotating shaft 22 is fixedly connected with a ratchet 25, the protective shell 16 is slidably provided with a limiting member 26, and a tension spring is installed between the protective shell 16 and the limiting member 26, the limiting member 26 is in contact with the ratchet 25, and is used to limit the rotation of the fourth rotating shaft 22, the cabinet body 1 is slidably provided with a sliding rod 27, a tension spring is installed between the sliding rod 27 and the cabinet body 1, the sliding rod 27 is in contact with the limiting member 26, and the top of the cabinet body 1 is slidably provided with an intercepting frame 28 fixed to the sliding rod 27.

[0049] In the above scheme, when the stopper 26 contacts the ratchet 25, the stopper 26 contacts the ratchet 25. Fig.10 Taking the middle direction as an example, looking from right to left, the ratchet 25 cannot rotate clockwise, and the limiting direction of the one-way bearing connected to the second fixed shell 21 is opposite to the limiting direction of the ratchet 25 and the limiting member 26. The tension spring between the limiting member 26 and the protective shell 16 is always in a stretched state, so that the limiting member 26 is close to the ratchet 25.

[0050] Specific working principle: When the device is in use, when the wind blows, the wind blows the impeller 18 to rotate clockwise (with the impeller 18 rotating clockwise). Fig. 9Taking the example of viewing from top to bottom), the impeller 18, the first rotating shaft 17 and the fan 19 are rotated, the first rotating shaft 17 drives the second rotating shaft 20 to rotate through the bevel gear set, the second rotating shaft 20 drives the third rotating shaft 211 to rotate through the axial magnetic pulling force generated by the magnet assembly, the third rotating shaft 211 drives the fourth rotating shaft 22 to rotate through the coil spring, but due to the limiting effect of the contact between the limiting member 26 and the ratchet 25, the fourth rotating shaft 22 cannot rotate. At this time, the rotation of the third rotating shaft 211 will twist the coil spring. When the elastic potential energy stored in the coil spring reaches the limit, the third rotating shaft 211 cannot rotate. At the same time, due to the limiting effect of the one-way bearing connected to the third rotating shaft 211, the third rotating shaft 211 remains stationary. At this time, the first rotating shaft 17 and the second rotating shaft 20 keep rotating, and the fan 19 rotates to stir the air in the cabinet 1.

[0051] When a bird from outside falls onto the interception frame 28, the interception frame 28 and the sliding rod 27 move downward due to the gravity of the bird, and the sliding rod 27 simultaneously stretches the connected connection, and the sliding rod 27 moves downward to squeeze the limit member 26. The limit member 26 moves to release the limit on the ratchet 25, and the subsequent coil spring releases the elastic potential energy to make the fourth rotating shaft 22 drive the hammer member 23 to rotate, and the hammer member 23 rotates and strikes the fixing member 24 to make a sound. The sound drives away the birds, preventing the birds from defecating and building nests on the cabinet 1, thereby extending the service life of the device.

[0052] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope provided by the present invention, which should be covered by the protection scope of the present invention.
