It can be used as a tool for calculating electricity consumption of households or enterprises, and is also the infrastructure for power suppliers to charge electricity users. In addition, the electricity meter box can also be used in conjunction with various power equipment, such as generators, transformers, capacitors, etc., to achieve real-time monitoring and control of the circuit operation status.

[0003] Traditional devices have some disadvantages during use: the meter box is generally placed outdoors or on construction sites and other dusty environments. During long-term use, dust is easily introduced into the meter box. Dust adheres to electronic devices and may damage the internal electronic devices. Filters are generally used to prevent dust. However, in actual use, the long-term dust isolation of the filter will cause the mesh to be clogged, affecting the heat dissipation effect of the internal electronic devices. In addition, most filters are fixed with screws, which makes it cumbersome to disassemble and clean them. Utility Model Content

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] like Figure 1-3 As shown, the utility model provides a technical solution: an electric meter box, comprising a main box body 1, an electric meter 2 is installed inside the main box body 1, a baffle frame 3 is fixed on one side of the main box body 1, a filter screen 102 is opened on the side wall of the main box body 1, a secondary fixing rod 310 is fixedly connected to the center of the filter screen 102, one end of the secondary fixing rod 310 is rotatably connected to a rotating block 308, and scrapers 309 for clinging to the filter screen 102 are respectively arranged on both sides of the rotating block 308, a casing 304 is fixed to the baffle frame 3, a dual-axis motor 302 is rotatably connected to the center of the casing 304, and a fan 301 is fixedly connected to the other end of the dual-axis motor 302, and a driving component is arranged on one side of the dual-axis motor 302.

[0019] During the specific implementation process, the scraper 309 can clean the filter 102 to keep its mesh from being blocked by dust. The auxiliary fixing rod 310 is used to fix and limit the movement of the driving component. The dual-axis motor 302 drives the end fan 301 to rotate to allow air to flow through the filter 102.

[0020] As an implementation method in this embodiment, Figure 3 As shown, the driving assembly includes a rotating rod 305, one end of which is rotatably connected to the casing 304, a driven gear 312 is fixedly sleeved on the outer wall of the rotating rod 305, a driving gear 311 is fixedly sleeved on the outer wall of the dual-axis motor 302, and the driving gear 311 is meshed with the driven gear 312, an inner ring gear 313 is provided on the inner wall of the casing 304, and the inner ring gear 313 is transmission-connected to the driven gear 312, the outer wall of the inner ring gear 313 is rotatably connected to the inner wall of the casing 304 through a bearing, one end of the rotating rod 305 is rotatably connected to the connecting rod 306, one end of the connecting rod 306 is fixedly connected to the auxiliary rod 307, and one end of the auxiliary rod 307 is fixedly connected to the rotating block 308.

[0021] During the specific implementation process, the motor drives the dual-axis motor 302 to rotate, and the driving gear 311 on the dual-axis motor 302 will drive the driven gear 312 to rotate. The driven gear 312 engages with the inner ring gear 313, thereby driving the rotating rod 305 to make a circular motion inside the casing 304, and the rotating rod 305 drives one end of the connecting rod 306 to make a circular motion. The other end of the connecting rod 306 is fixed on the auxiliary rod 307, so that the rotating rod 305 drives the end of the connecting rod 306 connected to the rotating rod 305 to rotate, and the end connected to the auxiliary rod 307 keeps the position unchanged and rotates, and the auxiliary rod 307 drives the rotating block 308 to rotate, and the rotating block 308 drives the scraper 309 to rotate, so as to clean the dust on the filter.

[0022] It should be further explained that the driving gear 311 has a smaller radius than the driven gear 312 , and the driving gear 311 rotates multiple times to drive the driven gear 312 to rotate one circle, so that the scraper 309 does not rotate quickly due to the rotation speed of the fan 301 , but rotates slowly in close contact with the filter 102 .

[0023] As an implementation method in this embodiment, Figure 2 As shown, four main fixing rods 303 are fixed to the outer side wall of the casing 304 , and the ends of the four main fixing rods 303 away from the casing 304 are fixed to the inner wall of the baffle frame 3 .

[0024] As an implementation method in this embodiment, Figure 1 As shown, the top of the main box body 1 is fixed and connected to a heat dissipation port 101 , and the bottom of the heat dissipation port 101 is connected to the interior of the main box body 1 .

[0025] During the specific implementation process, the electronic device generates heat due to operation. If the heat is not dissipated in time, the device may be damaged. The heat dissipation port 101 is used to dissipate heat inside the box.

[0026] As an implementation method in this embodiment, Figure 1 As shown, a ventilation duct 401 is fixedly connected to the bottom of the baffle frame 3 , and an air outlet end of the ventilation duct 401 extends to below the heat dissipation port 101 .

[0027] During the specific implementation process, the wind entering the box will generally be blocked, while the other side of the box is not ventilated, which may cause the temperature to be too high. The ventilation duct 401 can transport air to the other side of the box, and the heat dissipation port 101 is located above, which accelerates heat dissipation and improves internal air circulation.

[0028] As an implementation method in this embodiment, Figure 2As shown, a material guide trough 103 is provided on the outer wall of the main box body 1 , and the material guide trough 103 is provided on the inner bottom wall of the filter screen 102 . A collection frame 104 is provided on the outer wall of the main box body 1 , and the collection frame 104 is located below the discharge end of the material guide trough 103 .

[0029] During the specific implementation process, the scraper 309 scrapes off the dust on the filter screen 102, and the guide trough 103 allows the dust to fall into the collection frame below. There is water in the collection frame 104, and the dust impurities will be absorbed by the water to prevent secondary flying. Subsequently, only the collection frame needs to be cleaned.

[0030] Working principle: The double-axis motor 302 drives the end fan 301 to rotate so that air circulates through the filter 102. The servo motor 314 drives the double-axis motor 302 to rotate. The driving gear 311 on the double-axis motor 302 drives the driven gear 312 to rotate. The driven gear 312 meshes with the inner ring gear 313, thereby driving the rotating rod 305 to make a circular motion inside the casing 304. The rotating rod 305 drives one end of the connecting rod 306 to make a circular motion. The other end of the connecting rod 306 is fixed on the auxiliary rod 307, so that the rotating rod 305 can rotate in a circular motion. The movable rod 305 drives the end of the connecting rod 306 connected to the rotating rod 305 to rotate, and the end connected to the auxiliary rod 307 keeps the position unchanged and rotates. The auxiliary rod 307 then drives the rotating block 308 to rotate, and the rotating block 308 drives the scraper 309 to rotate, so as to clean the dust on the filter screen. The scraper 309 scrapes off the dust on the filter screen 102, and the guide trough 103 allows the dust to fall into the collection frame below. There is water in the collection frame 104, and the dust impurities will be absorbed by the water to prevent secondary dust. Later, only the collection frame needs to be cleaned.

[0031] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
