Description

Technical Field

[0001] This invention relates to the field of meter box technology, specifically to an outdoor meter box that is easy to maintain in rainy weather. Background Technology

[0002] Electricity meter boxes are mainly used in electrical facilities such as cable branch boxes, low-voltage distribution boxes, and street light and traffic light control boxes in public power grids. They are important electrical equipment in the power system.

[0003] For example, Chinese patent publication number "CN215599233U" discloses "An outdoor meter box rainproof device," whose main structure includes a bracket with a first side plate and a second side plate installed on it. One end of the first side plate is fixedly installed on the rear side of the bracket, and the bracket is installed on the top of the meter box via the first side plate. The top of the second side plate is rotatably installed on the front side of the bracket, and baffles are fixedly installed on both sides of the second side plate. This outdoor meter box rainproof device can block rainwater falling from the top through the bracket, preventing rainwater from flowing into the meter box through the ventilation holes at the top of the meter box, thus ensuring the safety of the meter inside the meter box. The second side plate and the baffles installed on the second side plate can block the gap between the meter box door and the meter box body, preventing rainwater from flowing into the meter box through the gap under the action of strong winds during rain, thus ensuring normal power supply.

[0004] In actual use, the horizontally angled wind deflector increases the wind resistance of the meter box when strong winds arrive (due to the increased cross-section of the wind deflector). The increased wind resistance reduces the meter box's compressive strength after installation, which can lead to loosening of the installation parts over time, seriously affecting the effective service life of the equipment. At the same time, the wind deflector at the top also reduces the light intensity during maintenance in rainy weather, which is not conducive to maintenance in rainy weather. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an outdoor meter box that facilitates maintenance in rainy weather. It enables basic ventilation inside the meter box and, during rainy maintenance, creates an air curtain at the required angle. This air curtain reduces rainwater falling into the maintenance area without reducing external sunlight intensity, thus facilitating maintenance and repair work in rainy weather and solving the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an outdoor meter box that is easy to maintain in rainy weather, comprising a meter box body with a lower air inlet on the back, an upper ventilation opening on the top of the meter box body, and two ventilation ducts for connection and ventilation; a wind-driven mechanism, the structure of which includes a first ventilation duct installed on the top of the meter box body and having a hollow internal structure, a horizontal rotating shaft installed inside the first ventilation duct and capable of rotation, a fan blade capable of rotating with the horizontal rotating shaft and causing air flow, and a drive motor installed on the top of the first ventilation duct and capable of driving the horizontal rotating shaft to rotate; and an angle-variable exhaust mechanism, the structure of which includes a second ventilation duct connected to the first ventilation duct through a ventilation duct and having a hollow internal structure, and a strip-shaped spherical exhaust shell installed on one side of the second ventilation duct and capable of adjusting the exhaust angle.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 and Figure 2 An outdoor meter box that is easy to maintain in rainy weather includes a meter box body 1 with a lower air inlet 2 on the back, an upper ventilation opening 3 on the top of the meter box body 1, and two ventilation ducts 4 for connection and ventilation. The meter box body 1 is installed as required. After installation, the flow rate of gas, i.e. the air volume, can be controlled by controlling the power of the drive motor 512. The drive motor 512 is a waterproof motor with waterproof performance.

[0021] To achieve ventilation and the formation of an air curtain, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 3 and Figure 4A wind-driven mechanism 5 needs to be installed. Its structure includes a first ventilation pipe 51 installed on the top of the meter box 1 and having a hollow internal structure, a horizontal rotating shaft 57 installed inside the first ventilation pipe 51 and capable of rotation, a fan blade 59 that can rotate with the horizontal rotating shaft 57 and cause air flow, and a drive motor 512 installed on the top of the first ventilation pipe 51 and capable of driving the horizontal rotating shaft 57 to rotate. When the drive motor 512 is started, the driven pulley 58 will drive the horizontal rotating shaft 57 to rotate, and the fan blade 59 will rotate accordingly. At this time, the gas enters through the lower ventilation port 54 and is discharged outward through the two first docking channels 55, thereby causing air flow. By controlling the power of the drive motor 512, the amount of air flow can be controlled, thereby realizing ventilation and the formation of an air curtain.

[0022] For details regarding the specific structure of the wind-driven mechanism 5, please refer to [link / reference]. Figure 3 and Figure 4 It also includes a first mounting base 52 integrally disposed at the bottom of the first ventilation pipe 51. The first ventilation pipe 51 has a first gas flow chamber 53 inside. The first mounting base 52 is fixedly installed at the top opening end of the ventilation duct 4. The first mounting base 52 has a lower ventilation port 54 connecting the ventilation duct 4 and the first gas flow chamber 53 inside. The first ventilation pipe 51 has first docking channels 55 at both ends. Two ventilation brackets 56 are fixedly installed inside the first gas flow chamber 53. Each ventilation bracket 56 has a rotatable horizontal shaft 57 installed in its base hole via a bearing. The two horizontal shafts 57 are aligned with each other. A driven pulley 58 is fixedly installed at the vertical end. Fan blades 59 are fixedly installed in the shaft of the horizontal rotating shaft 57. A horizontal drive motor 512 is fixedly installed at the top of the first ventilation pipe 51 via a motor mounting base 513. A drive pulley 510 is fixedly installed at the rotor end of the drive motor 512. The drive pulley 510 and the driven pulley 58 are linked by a synchronous belt 511 that runs through the first ventilation pipe 51. When the two fan blades 59 rotate, the resulting airflow enters through the lower ventilation port 54 and is discharged outward through the two first docking channels 55. The end of the horizontal rotating shaft 57 is provided with a pointed structure to reduce the degree of gas turbulence.

[0023] To adjust the air outlet angle and control the planar air curtain, please refer to [link / reference needed].

The gas entering the second ventilation pipe 61 will be discharged outward through the flat exhaust port 66. Due to the structure of the flat exhaust port 66, the air will form a planar air curtain and move outward. At this time, the falling rainwater will be away from the meter box 1 due to the planar air curtain, so as to reduce the degree of obstruction of rainwater to the staff during maintenance. By adjusting the angle of the strip-shaped spherical exhaust shell 65, the angle of the planar air curtain can be changed, thereby realizing the adjustment of the air outlet angle and the control of the planar air curtain.

[0024] For details regarding the specific structure of the variable-angle exhaust mechanism 6, please refer to [link / reference needed]. Figure 5 and Figure 6 It also includes a second mounting base 62 integrally set at the bottom of the second ventilation pipe 61. The second mounting base 62 is fixedly installed on one side of the upper surface of the meter box 1. The second ventilation pipe 61 is provided with a second gas flow chamber 63 inside. The two ends of the second ventilation pipe 61 are provided with second docking channels 67. One side of the second ventilation pipe 61 is provided with a strip-shaped spherical movable cavity 64 that connects to the outside space and one side of the second gas flow chamber 63. A rotatable strip-shaped spherical exhaust shell 65 is installed in the strip-shaped spherical exhaust shell 64. The inside of the strip-shaped spherical exhaust shell 65 is provided with a flat exhaust port 66 for discharging gas. Each of the second docking channels 67 is connected to a first docking channel 55 through a ventilation pipe 4. The cross-sectional structural dimensions of the strip-shaped spherical exhaust shell 65 are adapted to the cross-sectional structural dimensions of the strip-shaped spherical movable cavity 64.

[0025] To reduce the amount of rainwater entering the meter box 1 due to wind, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 7 and Figure 8 A rainproof air intake mechanism 7 needs to be installed. Its structure includes an air intake pipe 71 installed at the end of the lower air intake 2 for air intake, and an upper rainproof plate 74 and a lower rainproof plate 76 installed inside the air intake pipe 71 to reduce the amount of rainwater entering the meter box 1 with the air. When rainwater flows inside the air intake cavity 73, the upper rainproof plate 74 can block some of the rainwater from entering, while some rainwater and wind will enter the air intake cavity 73 through the lower ventilation opening 75. At this time, the lower rainproof plate 76 will block the rainwater from entering, while the air will change its path and enter the meter box 1 through the upper ventilation opening 77, thereby reducing the amount of rainwater entering the meter box 1 with the wind.

[0026] For details regarding the specific structure of the rainproof air intake mechanism 7, please refer to [link / reference]. Figure 7 and Figure 8 It also includes an integrally formed docking plate structure 72 at the end of the air intake pipe 71. The docking plate structure 72 is fixedly installed at the end of the lower air inlet 2. The air intake pipe 71 has an air intake chamber 73 with open ends. The upper half of the air intake port of the air intake chamber 73 is provided with an upper rain shield 74. The lower part of the upper rain shield 74 forms a lower ventilation notch 75. The lower half of the air intake chamber 73 near its exhaust end is provided with a lower rain shield 76. The upper part of the lower rain shield 76 forms an upper ventilation notch 77. The height of the upper rain shield 74 and the height of the lower rain shield 76 are both greater than the structural radius of the air intake chamber 73.

[0027] In use, the meter box 1 is installed as required. The drive motor 512 is started, and the driven pulley 58 drives the horizontal shaft 57 to rotate, causing the fan blades 59 to rotate accordingly. At this time, gas enters through the lower vent 54 and is discharged outwards through the two No. 1 docking channels 55, thus creating gas flow. The gas flow rate can be controlled by controlling the power of the drive motor 512. When rainwater flows inside the air intake chamber 73, the upper rain shield 74 can block some of the rainwater from entering, while some rainwater and wind force will enter the air intake chamber 73 through the lower vent 75. At this time, the lower rain shield... 76 will block the incoming rainwater, while the gas will change its path and enter the meter box 1 through the upper ventilation opening 77. The gas entering the second ventilation pipe 61 will be discharged outward through the flat exhaust port 66. Due to the structure of the flat exhaust port 66, the air will form a planar air curtain and move outward. At this time, the falling rainwater will be moved away from the meter box 1 due to the planar air curtain, so as to reduce the degree of obstruction of rainwater to the staff during maintenance. By adjusting the angle of the strip-shaped spherical exhaust shell 65, the angle of the planar air curtain can be changed, thereby realizing the adjustment of the air outlet angle and the control of the planar air curtain.
