For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1-5 As shown, the present embodiment provides an electric energy meter box with a protective structure, including an electric energy meter box 10, wherein a waterproof baffle 11 is fixedly connected to the top of the electric energy meter box 10 to prevent water from seeping from the top of the electric energy meter box, the cross-sectional shape of the waterproof baffle 11 is a trapezoid, and a rain shield 111 is movably connected inside the waterproof baffle 11, and the upper surface of the rain shield 111 is inclined, and the waterproof baffle 11 and the rain shield 111 are connected through a reset spring 113, one end of the reset spring 113 is connected to the bottom of the waterproof baffle 11, and the other end is connected to the bottom end of the rain shield 111. In the present embodiment, the rain shield 111 is pushed out from the inside of the waterproof baffle 11 by the elastic force of the reset spring 113, so as to block rainwater from the front door of the electric energy meter box, reduce rainwater from entering the electric energy meter box 10, and protect the components and other equipment inside the electric energy meter box housing 10, thereby reducing the damage of the components and other equipment.

[0029] like Figure 3-4 As shown, in order to reduce the tilting of the shielding plate 111 due to uneven force when it is pushed out, this embodiment provides limit grooves 112 for limiting sliding on both sides of the waterproof baffle 11, and a limit column 1111 that cooperates with the limit groove 112 is provided at the bottom of the rain shield 111. The limit column 1111 is fixed in the limit groove 112, and the limit column 1111 can slide along the limit groove 112. Through the coordinated sliding of the limit column 1111 and the limit groove 112, the sliding of the rain shield 111 is restricted, thereby reducing the tilting and sliding of the rain shield 111.

[0030] like Figure 1-2 As shown, a cabinet door 15 is arranged at the front of the electric energy meter box 10, and two cabinet doors 15 are symmetrically arranged. A baffle 151 is arranged on the top of one of them, and one end of the baffle 151 is connected to the cabinet door 151. The baffle 151 is arranged in an L shape. When the cabinet door 15 is closed, the baffle 151 can push the rain shield 111 into the interior of the limiting groove 112, and the reset spring 113 is in a compressed state at this time; when the cabinet door 151 is opened, the elastic force of the reset spring 113 pushes the rain shield 111 out from the interior of the waterproof baffle 11, and the rain shield 111 is pushed out along the limiting groove 112 through the limiting column 1111.

[0031] like Figure 5As shown, a filter device capable of filtering dust is disposed at the bottom of the electric energy meter box 10, and the filter device includes a filter screen 12 or a filter plate, which is a filter device with filter holes. In this embodiment, the filter 12 is taken as an example. The filter 12 is provided with a roller 16 capable of rolling on the surface of the filter 12. A plurality of protrusions 162 are evenly arranged on the circumference of the roller 16. The spacing between the protrusions 162 is the same as the spacing between the meshes of the filter 12. A rack 121 is provided on the side of the filter 12. A gear 161 matching the rack 121 is provided at one end of the roller 16. One end of the gear 161 provided on the roller 16 is connected to a sliding rod 122. One end of the sliding rod 122 is connected to a spring 123. The spring 123 is connected to the side wall of the electric energy metering box 10. In this embodiment, the sliding rod 122 is pushed to move by the elastic force of the spring 123, thereby driving the roller 16 to roll on the filter 12 along the rack 121. The protrusions 162 are inserted into the meshes of the filter 12 to squeeze out the dust in the meshes, thereby realizing rapid cleaning of the clogged meshes. When the cabinet door 15 is opened, the spring 123 pushes the sliding rod 122 to move, thereby quickly cleaning the blocked mesh, and when the cabinet door 15 is closed, the cabinet door 15 pushes the sliding rod 122 to move, and the mesh is cleaned again. The spring 123 can be replaced by a cylinder, an oil cylinder or a screw rod pair to drive the sliding rod 122 to move.

[0032] like Figure 6 As shown, the electric energy meter box 10 is provided with a fixing plate 12a above the filtering device, and the fixing plate 12a is used to install the heat dissipation device 17, and the heat dissipation device includes a fan 172, and the fan 172 is fixed on the surface of the fixing plate 12a by means of a fixing frame 172. In this embodiment, the fan 172 allows cold air to enter the interior of the electric energy meter box 10 to replace the hot air inside the electric energy meter box 10, thereby avoiding the situation where the internal temperature of the electric energy meter box 10 is too high and the internal components of the electric energy meter box 10 are damaged.

[0033] The fan 172 of the heat dissipation device 17 at the bottom of the power meter box 10 allows cold air to enter the interior of the power meter box 10. In this embodiment, the filter 12 filters out dust in the cold air of the power meter box 10 to prevent dust from entering the interior of the power meter box 10.

[0034] like Figure 7As shown, the two side walls of the electric energy meter box 10 are symmetrically provided with filter devices, which are provided at the upper part of the side walls. In this embodiment, the left side wall 13 is provided with a filter screen 131, and the right side wall 14 is provided with a filter screen 141. In this embodiment, the filter screens 131 and 141 are provided in the same manner. In this embodiment, only the filter screen 131 of the left side wall 13 is described. The filter device of the left side wall 13 is basically the same as the filter device provided at the bottom, except that one end of the drum 16a is connected to a slider 163, which is connected to the telescopic end of the cylinder 18. The slider 163 is driven to move by the telescopic end of the cylinder 18, so that the drum 16a rolls along the rack provided with the filter screen 131, and the convex point 162a is inserted into the mesh of the filter screen 131 to squeeze out the dust in the mesh, thereby realizing the rapid cleaning of the blocked mesh. The cylinder 18 can be replaced by an oil cylinder or a screw pair.

[0035] In this embodiment, three filtering devices are arranged in the power meter box 10, so that the air inside the power meter box 10 can be quickly exchanged with the external air, thereby effectively dissipating the heat inside the power meter box 10, and a heat dissipation device 17 is arranged at the bottom of the power meter box for heat dissipation. The rotation of the fan 172 accelerates the exchange of hot and cold air, and the hot air inside the power meter box 10 can flow out from the filter screens on the left wall 13 and the right wall 14, so that the heat dissipation effect is better.
