[0019] As attached Figure 1-4 A safe electric energy meter box is shown, comprising a meter box body 1, a box door 2 is movably mounted on the surface of the meter box body 1, and a plurality of glass observation windows 3 are arranged on the surface of the box door 2, a sealing gasket is arranged at the connection between the box door 2 and the meter box body 1, and a groove 14 is arranged on the surface of the box door 2.

[0020] Specifically, a large number of electrical equipment are installed inside the meter box body 1. The staff can open the box door 2 through the pull groove 14 to inspect the electrical equipment inside the meter box body 1, and the user can view the power value of the electric meter in the meter box body 1 through the glass observation window 3 on the surface of the box door 2. The sealing gasket at the connection between the box door 2 and the meter box body 1 can improve its sealing performance and prevent the inside of the meter box body 1 from getting damp and affecting the electrical equipment, thereby causing a safety accident.

[0021] Combined with Figure 1 , 3 As shown in Figure 4, the surface of the box door 2 is provided with a cleaning structure for cleaning the glass observation window 3, and the cleaning structure includes two groups of support blocks 4, and the two groups of support blocks 4 are fixedly mounted on the surface of the box door 2. The number of support blocks 4 in each group is set to two, and a screw rod 5 is arranged between two of the support blocks 4, and a slide rod 6 is arranged between the other two support blocks 4. A threaded block 7 and a slider 8 are respectively arranged on the outside of the screw rod 5 and the slider 6. A movable plate 9 is jointly installed on the surfaces of the threaded block 7 and the slider 8, and a cleaning cotton 10 is arranged on the back of the movable plate 9. A motor 11 is arranged at one end of the screw rod 5, and the output end of the motor 11 is coaxially connected to the screw rod 5. The threaded block 7 and the slider 8 are connected to the screw rod 5 and the slide rod 6 by threaded connection and sliding connection respectively, and the threaded block 7 and the slider 8 are fixedly mounted on the back of the movable plate 9.

[0022] Specifically, in this structure, when the meter box body 1 is installed outdoors, it is easy to cause a large amount of dust and stains to adhere to the glass observation window 3, affecting the user's viewing of the power value, and then the motor 11 can be used to drive the rotation of the screw rod 5 to move the threaded block 7. The movement of the threaded block 7 enables the movable plate 9 to move laterally under the sliding guidance of the slider 8 and the slide rod 6, and drives the cleaning cotton 10 to move and wipe the glass observation window 3, thereby cleaning and wiping the glass observation window 3.

[0023] In a specific embodiment, as shown in the attached Figure 1 As shown, two support plates 12 are arranged on the top of the metering box body 1, and the tops of the two support plates 12 jointly support a protective plate 13, and both ends of the protective plate 13 are inclined.

[0024] Specifically, in this structure, a good protective effect can be achieved for the meter box body 1. The protective plate 13 can be connected to the meter box body 1 through the support plate 12, so that the protective plate 13 can protect the meter box body 1 and prevent the meter box body 1 from being damaged by falling objects or rain.

[0025] In a specific embodiment, as shown in the attached Figure 1 , 2 As shown, a heat sink 15 is provided on the outer wall of the metering box body 1. The heat sink 15 is communicated with the outer wall of the metering box body 1. A dustproof net 16 is installed on the outer wall of the heat sink 15. A bracket 17 is provided inside the heat sink 15. A cooling fan 18 is provided inside the bracket 17.

[0026] Specifically, in this structure, the heat sink 15 is connected to the meter box body 1, and the heat dissipation fan 18 is installed inside the heat sink 15 through the bracket 17. Therefore, when the heat dissipation fan 18 is running, it can bring out the heat inside the meter box body 1, thereby having a heat dissipation effect on the inside of the meter box body 1, avoiding the excessive temperature of the meter box body 1 to affect the power equipment, and the dustproof net 16 at the heat sink 15 can prevent dust from entering on the one hand, and ensure that heat can be discharged on the other hand.

[0027] Working principle of this utility model:

[0028] When the above structure is used, a large number of power equipment are installed inside the meter box body 1, including power meters, voltage and current transformers for measurement and their secondary circuits, power metering screens and other equipment. The staff can open the box door 2 through the groove 14 to inspect the power equipment inside the meter box body 1, and check the power value of the meter inside the meter box body 1 through the glass observation window 3 on the surface of the box door 2. The sealing gasket at the connection between the box door 2 and the meter box body 1 can improve its sealing performance, so as to prevent the inside of the meter box body 1 from being affected by moisture and causing the power equipment, thereby causing safety accidents.

[0029] When dust and stains are attached to the glass observation window 3 on the surface of the box door 2, which affects the staff's ability to view the power value of the electric meter, the motor 11 is used to drive the screw rod 5 to rotate, so that the threaded block 7 moves. The movement of the threaded block 7 causes the movable plate 9 to move laterally under the sliding guide of the slider 8 and the slide rod 6, and drives the cleaning cotton 10 to move and wipe the glass observation window 3, thereby cleaning the glass observation window 3;

[0030] The protective plate 13 can protect the meter box body 1 to prevent falling objects or rain from damaging the meter box body 1. The cooling fan 18 can bring out the heat inside the meter box body 1, thereby cooling the inside of the meter box body 1 to prevent the excessive temperature of the meter box body 1 from affecting the power equipment. The dustproof net 16 at the heat dissipation box 15 can prevent dust from entering on the one hand, and ensure that heat can be discharged on the other hand.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
