Meter boxes are primarily used in power plants, substations, petrochemicals, metallurgy and steel rolling, light industry and textiles, factories and mines, residential areas, high-rise buildings, and other diverse settings. In related technologies, most electricity meter boxes are installed outdoors and are often exposed to many adverse weather conditions such as wind, sun, and rain. The meter boxes are easily penetrated by rainwater, and their internal electrical components are prone to malfunction, which affects the service life of the electricity meter boxes. Summary of the Invention

A plurality of connecting holes are opened on the inner partition; The heat dissipation device includes: The fan is connected to the waterproof box, and the fan is connected to an air outlet pipe, and the air outlet of the air outlet pipe is opened toward the bottom of the main box; The guide plate is connected to the waterproof box, and an arc-shaped guide groove is opened in the guide plate; There are several air outlet holes on the top of the main box; When the fan is started, the airflow generated by the fan first contacts the bottom surface of the main box body, flows along the inner partition and the surface of the main box body, flows into the main box body through the heat dissipation holes, and flows out from the air outlet. The airflow flows along the guide groove of the guide plate and changes the flow direction, and is finally discharged from the ventilation holes and drain outlet.

[0005] By adopting the above technical solution, the waterproof box is put on the outside of the main box, which can prevent external rainwater from entering the main box. The ventilation holes and heat dissipation holes facilitate air circulation to achieve heat exchange. The drain port and the inclined bottom surface can allow rainwater that accidentally enters the waterproof box to be discharged; the "U"-shaped inner partition separates the main box from the waterproof box, and the connecting holes allow the airflow to circulate better; the airflow generated by the fan first contacts the bottom surface of the main box, then enters the main box through the heat dissipation holes to take away heat and flows out from the air outlet, and then changes direction along the guide plate guide groove and is discharged from the ventilation holes and drain port, thereby achieving heat dissipation of the main box and improving the service life of the electricity metering box.

[0006] Optionally, the ventilation holes are opened tilted toward the upper end surface of the main box body, and the tilt angle is 30°-50°, and the connecting holes, heat dissipation holes and ventilation holes correspond to the tilt directions.

[0007] By adopting the above technical solution, the ventilation holes are opened at an angle to prevent rainwater from directly entering the waterproof box. The connecting holes and the heat dissipation holes correspond to the inclination direction of the ventilation holes, so that the outside air can flow smoothly from the ventilation holes into the heat dissipation holes to realize heat exchange inside the main box body, and facilitate the airflow to flow in the set direction to discharge the condensation on the waterproof box and the vertical plate.

[0009] By adopting the above technical solution, the waterproof device can prevent external rainwater from entering the main box, and the heat dissipation device can cool the surface of the main box, thereby increasing the service life of the electricity meter box; the connection between the limit rod and the first slide rail, and the vertical plate and the second slide rail enables the vertical plate to move smoothly, making it easy to adjust the position of the connecting hole to control the inflow of external air, thereby optimizing the heat exchange efficiency of the main box.

[0010] Optionally, the waterproof box is connected to a battery with adjustable output power above the main box body, the battery is connected to an electromagnet through a wire, and the electromagnet is embedded in the guide plate; the end of the vertical plate away from the flat plate is connected to a metal sheet, and the electromagnet is magnetically attracted to the metal sheet when energized.

[0011] By adopting the above technical solution, the battery with adjustable output power is connected to the electromagnet embedded in the guide plate through a wire, and cooperates with the metal sheet on the vertical plate. When the electromagnet is energized, magnetic attraction is used to control the movement of the vertical plate, thereby adjusting the position of the connecting hole, and the ventilation and heat dissipation conditions of the main box can be adjusted according to actual needs.

[0012] Optionally, the main box is connected to a temperature sensor, the temperature sensor is connected to a control panel, the control panel is connected to the box door of the main box, and the control panel is electrically connected to the battery; a drive button is provided on the limit rod, and the drive button is electrically connected to the fan; when the temperature inside the main box rises, the control panel adjusts the output power of the battery to adjust the position of the connecting hole and the heat dissipation hole; when the temperature inside the main box reaches the threshold of the temperature sensor, the battery is powered off and the electromagnet is disconnected from the metal sheet.

[0013] By adopting the above technical solution, the temperature sensor can monitor the temperature changes inside the main box in real time and transmit the data to the control panel. The control panel adjusts the battery output power according to the temperature conditions, and then adjusts the position of the connecting hole and the heat dissipation hole, so that the outside air can enter the main box more smoothly to achieve heat exchange and improve the heat dissipation efficiency; when the temperature inside the main box reaches the threshold, the battery is powered off and the electromagnet is disconnected from the metal sheet. At this time, the drive button on the limit rod can start the fan, and the airflow generated by the fan is used to enhance heat dissipation, thereby ensuring the normal operation of the electricity meter box and extending its service life.

[0014] Optionally, a humidity sensor is connected to the waterproof box, and the humidity sensor is electrically connected to the control panel.

[0015] By adopting the above technical solution, the humidity sensor is electrically connected to the control panel and can drive the battery to stop supplying power when it is detected that the humidity exceeds the threshold, thereby avoiding water accumulation inside the waterproof box.

[0016] Optionally, a conical air duct is connected to the inner partition, the air outlet pipe of the fan is connected to the side wall of the conical air duct, and the angle between the tangent of the cross-section circle at the connection between the conical air duct and the air outlet pipe and the axis of the air outlet pipe is less than 90°.

[0017] By adopting the above technical solution, when the airflow generated by the fan enters the conical air duct through the air outlet pipe, it can flow along the side of the conical air duct to form a rotating airflow, which is conducive to the subsequent flow and heat dissipation of the air between the waterproof box and the main box.

[0019] By adopting the above technical solution, the moisture-absorbing sponge pad can be used to absorb moisture from the airflow generated by the fan, reducing the moisture carried by the airflow entering the waterproof box, and preventing the normal operation of the electricity meter box due to water carried by the airflow. At the same time, the airflow generated by the fan can form a rotating airflow when it enters the conical air duct through the air outlet pipe. The rotating airflow first contacts the bottom surface of the main box body, flows along the inner partition and the surface of the main box body, flows into the main box body through the heat dissipation holes, and flows out of the air outlet. It then changes direction through the guide plate guide groove and is discharged through the ventilation holes and drain outlet, achieving heat exchange within the main box body and the removal of condensation from the waterproof box and vertical plates.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The waterproof device can prevent external rainwater from entering the main box. The drain port can allow rainwater that accidentally enters the waterproof box to flow out along the inclined bottom surface, preventing internal components from short-circuiting due to water accumulation; 2. The heat dissipation device can cool the surface of the main box. The airflow generated by the fan can flow into the main box through the heat dissipation holes and out of the air outlet holes, thereby increasing the efficiency of heat exchange in the main box and extending the service life of the energy meter box. 3. The battery output power can be adjusted according to the temperature inside the main box through the temperature sensor and control panel, and then the position of the connecting hole and the heat dissipation hole can be adjusted. When the axis of the connecting hole and the heat dissipation hole coincides, the heat exchange efficiency can be increased. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1 -Attached Figure 8 , further details of this application are given.

[0024] Example 1: A waterproof electric energy meter box, refer to Figure 1 、 Figure 2 , including a main box body 1 and a waterproof device 2 and a heat dissipation device 3 matched therewith, wherein the waterproof device 2 is used to prevent external rainwater from entering the main box body 1; the heat dissipation device 3 is used to cool the surface of the main box body 1 to improve the service life of the electric energy meter box.

[0025] The waterproof device 2 includes a waterproof box 201 that fits over the main housing 1. The waterproof box 201 has an opening, and a door that opens outwards is pivotally connected to the opening. A sealing strip 202 is also fixedly connected to the opening. When the door is rotated and the waterproof box 201 is closed, it effectively prevents rainwater from entering the waterproof box 201 through the gap in the door. Furthermore, the door of the main housing 1 and the door of the waterproof box 201 rotate and open in the same direction, and the door of the main housing 1 is smaller than that of the waterproof box 201. Furthermore, the outer surface of the main housing 1, facing away from the door, is fixedly connected to the inner wall of the waterproof box 201, facilitating the opening of the main housing 1.

[0026] Reference Figure 3 、 Figure 4 The waterproof case 201 is provided with a plurality of ventilation holes 4 on both sides. The ventilation holes 4 extend upward from the outer surface of the waterproof case 201 toward the top surface of the main case 1, and the opening angle of the ventilation holes 4 is 45 degrees. Furthermore, the main case 1 and the waterproof case 201 are provided with heat dissipation holes 5 on both sides of the waterproof case 201. The heat dissipation holes 5 and the ventilation holes 4 have the same opening angle and orientation. Furthermore, the heat dissipation holes 5 and the ventilation holes 4 are coaxially arranged, allowing outside air to flow into the heat dissipation holes 5 from the diameter of the ventilation holes 4 in the waterproof case 201, thereby achieving heat exchange within the main case 1. Furthermore, the bottom surface of the waterproof case 201 is provided with a drain port 6 on both sides. The bottom surface of the waterproof case 201 between the two drain ports 6 is a curved plate, and the curved plate is raised in an arc toward the main case 1. When rainwater accidentally enters the waterproof case 201, the rainwater inside can flow out through the drain port 6 along the curved plate.

[0027] Reference Figure 2 、 Figure 5A U-shaped inner partition is fixedly connected to the waterproof box 201. The inner partition is located between the waterproof box 201 and the main box 1, separating the sides and bottom of the main box 1 from the waterproof box 201. A gap is provided between the inner partition, the waterproof box 201, and the main box 1. The inner partition includes a flat plate 203 and two vertical plates 204. Both sides of the flat plate 203 are fixedly connected to the inner wall of the waterproof box 201. A limit rod 205 is fixedly connected to the upper end surface of the flat plate 203. The two sides of the limit rod 205 are fixedly connected to the inner wall of the waterproof box 201.

[0028] Reference Figure 4 、 Figure 6 A limiting groove 7 is defined on the vertical plate 204. A first slide rail 8 is fixedly connected to the inner wall of the limiting groove 7. A slider is also fixedly connected to a limiting rod 205. When the vertical plate 204 and the flat plate 203 are assembled, the slider extends into the first slide rail 8 and slides along the first slide rail 8. Furthermore, a second slide rail 9 is fixedly connected to the inner wall of the waterproof box 201. Both the vertical plate 204 and the limiting rod 205 on the vertical plate 204 extend into the second slide rail 9, and the vertical plate 204 slides along the second slide rail 9.

[0029] Reference Figure 2 、 Figure 4 、 Figure 5 The vertical plate 204 is provided with a connecting hole 10 that is aligned with the heat dissipation holes 5 and ventilation holes 4 in an angle and orientation consistent with the axis of the connecting hole 10, and the axis of the connecting hole 10 is parallel to the axis of the heat dissipation holes 5 and ventilation holes 4. Furthermore, the waterproof case 201 is fixedly connected to a battery 206 on the upper end face of the main case 1. The battery 206 can adjust the output power. The battery 206 is connected to an electromagnet 207 via a wire, wherein the electromagnet 207 is located above the vertical plate 204. At the same time, a metal sheet 208 is fixedly connected to the end of the vertical plate 204 near the electromagnet 207. When the battery 206 energizes the electromagnet 207, magnetic attraction occurs between the electromagnet 207 and the metal sheet 208, thereby controlling the vertical plate 204 to slide on the second slide rail 9 and the first slide rail 8.

[0030] Reference Figure 2 、 Figure 4 、 Figure 6A control panel 209 is fixedly connected to the surface of the main housing 1, and a temperature sensor for monitoring the temperature changes inside the main housing 1 in real time is fixedly connected inside the main housing 1. The temperature sensor is electrically connected to the control panel 209, so that the temperature inside the main housing 1 is displayed on the control panel 209. In addition, the control panel 209 is electrically connected to the battery 206, and the power output of the battery 206 can be adjusted through the control panel 209. When the temperature inside the main housing 1 gradually rises, the power output of the battery 206 gradually decreases, thereby weakening the magnetic attraction of the electromagnet 207 to the metal sheet 208, causing the vertical plate 204 to slide closer to the flat plate 203 under its own weight, thereby causing the axis of the connecting hole 10 to gradually approach the axis of the heat dissipation hole 5 and the ventilation hole 4. When the axis of the connecting hole 10 coincides with the axis of the heat dissipation hole 5 and the ventilation hole 4, the battery 206 stops discharging the metal sheet 208, and at this time the air flowing from the outside can flow smoothly into the ventilation hole 4, the connecting hole 10, and the heat dissipation hole 5, thereby increasing the efficiency of heat exchange in the main box 1.

[0031] Reference Figure 2 、 Figure 7 The heat dissipation device 3 includes a conical air duct 301 fixedly connected to the middle portion of the curved plate on the bottom surface of the waterproof box 201. The opening of the conical air duct 301 is located on its large end surface, facing the bottom surface of the main box 1 and fixedly connected to the flat plate 203. The small end surface of the conical air duct 301 is closed. In addition, the bottom surface of the waterproof box 201 is provided with a plurality of air inlet holes. At the same time, a fan 302 is fixedly connected to the waterproof box 201, and an air outlet pipe 303 is connected to the fan 302. The air outlet pipe 303 is fixedly connected to the side wall of the conical air duct 301. In addition, the angle between the tangent of the cross-section circle at the connection between the conical air duct 301 and the air outlet pipe 303 and the axis of the air outlet pipe 303 is less than 90 degrees. In this way, when the airflow generated by the fan 302 enters the conical air duct 301 through the air outlet pipe 303, the airflow can flow around the side of the conical air duct 301 and form a rotating airflow. In addition, a moisture-absorbing sponge pad 304 is fixedly connected to the inner wall of the conical air duct 301, and the moisture-absorbing sponge pad 304 is covered on the connection between the air outlet pipe 303 and the conical air duct 301, so as to absorb the moisture in the air flow generated by the fan 302, thereby reducing the moisture carried by the air flow blown into the waterproof box 201.

[0032] Reference Figure 4 、 Figure 5 、 Figure 6A drive button 305 is fixedly connected to the limit rod 205 of the flat panel 203. The drive button 305 is used to control the activation of the fan 302. When the battery 206 stops supplying power, the vertical panel 204 cooperates with the drive button 305 to activate the fan 302. Furthermore, a sloped panel 306 is fixedly connected to the side of the vertical panel 204 near the fan 302. When the sloped panel 306 abuts the flat panel 203, the sloped panel 306 ensures a smooth transition between the sidewalls of the flat panel 203 and the vertical panel 204. Simultaneously, a deflector plate 307 is fixedly connected to the inner wall of the waterproof case 201 above the vertical panel 204. The side of the deflector plate 307 near the vertical panel 204 has an arc-shaped guide groove, and the side of the deflector plate 307 away from the main housing 1 smoothly transitions to the inner wall of the waterproof case 201. The electromagnet 207 is embedded in the deflector plate 307. Furthermore, the first slide rail 8 is fixedly connected to the deflector plate 307.

[0033] Reference Figure 2 、 Figure 4 The top surface of the main housing 1 is provided with a number of air outlets 11. When the fan 302 is operating, the rotating airflow generated by the fan 302 first contacts the bottom surface of the main housing 1. Then, in the coordinated direction of the waterproof case 201, the main housing 1, and the flat panel 203, the airflow flows along the vertical panels 204 on either side of the main housing 1. The airflow is redirected by the sloped panels 306, causing the airflow to flow toward the upper end surface of the waterproof case 201. When the airflow is located between the vertical panels 204 and the main housing 1, because the connecting holes 10 and the heat dissipation holes 5 are inclined upward toward the top surface of the main housing 1, some of the airflow flows into the main housing 1 through the heat dissipation holes 5, forcing heat to dissipate from the electrical components within the main housing 1. The airflow then flows out through the air outlets 11, simultaneously dissipating heat from the battery 206. Another portion of the airflow flows toward the guide plate 307, where it redirects along the guide grooves of the guide plate 307, causing the airflow to flow toward the bottom surface of the waterproof case 201. When the air flow is located between the vertical plate 204 and the waterproof box 201, since the ventilation holes 4 and the connecting holes 10 are opened upward and inclined toward the top surface of the main box body 1, part of the air flow can flow out from the ventilation holes 4 to the outside, and the other part of the air flow flows along the inner wall of the waterproof box 201 toward the drain port 6, thereby discharging condensation on the waterproof box 201 and the vertical plate 204.

[0034] A humidity sensor is fixedly connected to the side wall inside the waterproof box 201 below the ventilation hole 4, and the humidity sensor is electrically connected to the control panel 209. When the humidity detected by the humidity sensor exceeds the threshold, the control panel 209 can drive the battery 206 to stop supplying power, thereby preventing the humidity inside the waterproof box 201 from being too high.

[0035] The implementation principle of this embodiment is as follows: This waterproof electricity meter box achieves an effective combination of waterproofing and heat dissipation through the unique design of waterproof device 2 and heat dissipation device 3. The inclined ventilation holes 4, drain port 6, and inclined bottom design of the waterproof box 201 prevent rainwater from entering and promptly drain out accumulated water; the movable structure of the inner partition can adjust the airflow channel according to the temperature inside the main box 1; the heat dissipation device 3 uses the airflow generated by the fan 302 to circulate along a specific path to remove heat. The installation of humidity sensors and temperature sensors can automatically adjust the operation of related components according to the environment and the conditions inside the main box 1. Compared with traditional electricity meter boxes, this greatly improves waterproofing and heat dissipation performance, extends the service life of electrical components, reduces the probability of failure, and provides a strong guarantee for the stable operation of the power system.

[0036] Example 2: A waterproof electric energy meter box, refer to Figure 4 、 Figure 8 The difference between this embodiment and Example 1 is that the inclination angles of the ventilation holes 4, heat dissipation holes 5, and communication holes 10 can be adjusted according to the actual usage environment. In areas with strong winds and little rainfall, the inclination angle can be appropriately increased, for example, to 30°-40°, to better guide the airflow and improve heat dissipation efficiency. In areas with frequent rainfall and light winds, the inclination angle can be adjusted to 45°-50° to enhance the waterproof effect.

[0037] The principle behind this embodiment is that by adjusting the inclination angles of the ventilation holes 4, heat dissipation holes 5, and communication holes 10, the device can better adapt to different environmental conditions. Flexible adjustment of the inclination angles allows for a more appropriate balance between waterproofing and heat dissipation in different geographical regions and climates, further optimizing the performance of the energy meter box, enabling stable operation in a variety of complex environments. This expands the product's scope of application and enhances its versatility and practicality.

Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
