[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a protective shell device for an electricity metering box, including a shell 1. The shell 1 serves as the external protective structure of the entire device, providing installation space and protection for various internal components. Its robust material can withstand external collisions and environmental factors. A fixing plate 2 is fixedly connected inside the shell 1. The fixing plate 2 supports and fixes other components inside the shell 1 and provides a basic structure for the setting of the limiting mechanism. A limiting mechanism is set inside the fixing plate 2. The limiting mechanism is mainly used to limit and fix the filter screen 3, ensuring the stability of the filter screen 3 during operation, and also facilitating its disassembly and cleaning.

[0035] The limiting mechanism includes a filter screen 3, which effectively blocks external dust and debris from entering the electricity metering box, protecting the internal metering equipment. The filter screen 3 is externally slidably connected to the inside of the fixed plate 2, allowing it to slide within the plate. The fixed plate 2 is designed with a sliding structure that matches the filter screen 3, ensuring smooth sliding and facilitating subsequent cleaning and replacement. A limiting block 4 is internally slidably connected to the fixed plate 2, playing a crucial role in limiting the position of the filter screen 3. Once the filter screen 3 is installed, the limiting block 4 restricts its position, preventing it from loosening or shifting. A telescopic column 5 is fixedly connected to the end of the limiting block 4 away from the filter screen 3. The telescopic column 5 provides support and guidance for the movement of the limiting block 4 and can drive the limiting block 4 to extend and retract under the action of the telescopic spring 6. The telescopic spring 6 is sleeved on the outside of the telescopic column 5.

[0036] The telescopic spring 6 is elastic and can deform under external force. When the filter screen 3 is operated, the telescopic spring 6 will push or pull the limit block 4 according to the operation, realizing the limiting and unlocking functions of the filter screen 3. The fixed plate 2 has a sliding opening 8 inside, which provides a channel for the installation and removal of the filter screen 3. The filter screen 3 can slide inside the fixed plate 2 through the sliding opening 8. The outside of the filter screen 3 is slidably connected to the inside of the sliding opening 8. Multiple ventilation fans 17 are fixedly connected to the outside of the fixed plate 2. When the power metering box is working, the ventilation fans 17 can promote the circulation of internal air and accelerate the heat dissipation. At the same time, when cleaning the filter screen 3, the blowing of the ventilation fans 17 can expel dust to the outside of the housing 1, improving the cleaning effect.

[0037] The outer surface of the limiting block 4 is arc-shaped. The arc design of the limiting block 4 is to allow for smoother contact and separation with the filter screen 3 during installation and disassembly. The outer surface of the limiting block 4 contacts the outer surface of the filter screen 3. After the filter screen 3 is installed in place, the arc-shaped surface of the limiting block 4 fits tightly with the filter screen 3, thereby achieving the limiting and fixing of the filter screen 3. The rear end of the telescopic column 5 is fixedly connected to the inside of the housing 1. This connection method ensures the stability of the telescopic column 5, enabling it to accurately drive the limiting block 4 to telescopic movement under the action of the telescopic spring 6. The front end of the telescopic spring 6 is fixedly connected to the rear end of the limiting block 4.

[0038] The front end of the telescopic spring 6 is fixedly connected to the rear end of the limiting block 4, so that the telescopic spring 6 can effectively apply force to the limiting block 4 and realize the telescopic movement of the limiting block 4. The other end of the telescopic spring 6 is fixedly connected to the inside of the housing 1, providing a fixed support point for the telescopic spring 6 and ensuring the normal functioning of its elasticity. The housing 1 is rotatably connected to the outside of the rotating shaft 7, and the rotating door 16 is fixedly connected to the outside of the rotating shaft 7, so that the rotating door 16 can open and close around the rotating shaft 7.

[0039] Reference Figure 1 , Figure 2 and Figure 5 The adjustment mechanism includes a rotating column 9, which is an important component of the adjustment mechanism. The rotation of the rotating column 9 can drive the ventilation plate 12 to rotate, thereby adjusting the size of the ventilation opening. The external rotating column 9 is rotatably connected to the inside of the housing 1. The housing 1 is designed with a rotating structure that matches the rotating column 9, ensuring that the rotating column 9 can rotate flexibly inside the housing 1. The external rotating column 9 is fixedly connected to the ventilation plate 12, which rotates with the rotation of the rotating column 9. By changing the angle of the ventilation plate 12, the size of the ventilation opening can be adjusted to meet different heat dissipation requirements. The external rotating column 9 is fixedly connected to a transmission rod 10, which transmits power to enable the rotating column 9 to rotate. The end of the transmission rod 10 away from the rotating column 9 is rotatably connected to a sliding block 11.

[0040] A cylinder 14 is fixedly connected to the top of the sliding block 11. The sliding block 11 slides in the slide groove 13 under the drive of the cylinder 14. The linear motion of the sliding block 11 is converted into the rotational motion of the rotating column 9 through the transmission rod 10. The cylinder 14 serves as a power source and drives the sliding block 11 to slide in the slide groove 13 through telescopic motion, thereby realizing the rotational control of the rotating column 9. The outer side of the housing 1 is provided with a slide groove 13, which provides a track for the sliding block 11 to slide, ensuring the stability and accuracy of the sliding block 11 during the sliding process. The outer side of the sliding block 11 is slidably connected to the inside of the slide groove 13. The matching design of the sliding block 11 and the slide groove 13 allows the sliding block 11 to slide smoothly in the slide groove 13, thereby effectively transmitting the power of the cylinder 14 to the rotating column 9.

[0041] The cylinder 14 is externally fixed to the outside of the housing 1. This installation method ensures the stability of the cylinder 14, enabling the cylinder 14 to reliably drive the sliding block 11 to perform sliding operations. A shield 15 is fixedly connected to the top of the housing 1. The shield 15 can provide rainproof and sunproof protection for the electricity metering box, reduce the impact of external environmental factors on the electricity metering box, and extend its service life. When the electricity metering box is in use, the start of the cylinder 14 can be controlled by the built-in inspection component. The built-in inspection component can monitor parameters such as the internal temperature of the electricity metering box in real time. When it is necessary to adjust the size of the ventilation opening, a signal will be sent to control the cylinder 14 to start, so as to achieve the effect of ventilation opening adjustment.

[0042] Working principle: When in use, the electricity metering box can control the start of cylinder 14 through the built-in inspection component. The start of cylinder 14 drives the sliding block 11 to slide inside the slide groove 13. The rotating column 9 is driven by the transmission rod 10 to rotate inside the housing 1. The rotation of the rotating column 9 drives the ventilation plate 12 to rotate, thus achieving the condition of the ventilation opening size of the entire metering box to meet the heat dissipation needs at different times and ensuring the normal operation of the internal machinery of the metering box.

[0043] When the filter screen 3 needs cleaning, it slides inside the fixed plate 2 by pressing it, thus releasing the restriction on the filter screen 3. At this time, the telescopic spring 6 will push the limit block 4 to slide, allowing the filter screen 3 to slide inside the fixed plate 2 and collide with the inside of the fixed plate 2. Through the vibration of the filter screen 3 itself, the dust on the surface of the filter screen 3 can be quickly cleaned. And through the blowing of the ventilation fan 17, the dust can be effectively guided and discharged to the outside of the housing 1, achieving a quick cleaning effect and reducing cleaning time. At the same time, when the filter screen 3 needs to be replaced, simply push the filter screen 3 in the fixed plate 2. The filter screen 3 slides vertically inside the plate 2 and slides horizontally inside the fixed plate 2, thus completing the removal of the filter screen 3. The new filter screen 3 slides into the fixed plate 2 from the sliding opening 8. The arc-shaped design of the limiting block 4 can automatically slide inside the fixed plate 2, thereby allowing the filter screen 3 to slide. After the operator releases control of the filter screen 3, the telescopic spring 6 will continuously push the limiting block 4 to slide, thereby restricting the position of the filter screen 3 to complete the installation of the filter screen 3. By quickly removing and installing the filter screen 3, the replacement time of the filter screen 3 is reduced, and the maintenance efficiency is improved.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
