[0015] (3) The present invention sets a dehumidification device so that the motor 2, the rotating shaft, the fan blades, the S-shaped guide plate and the dehumidification block cooperate with each other, so that the rotation of the fan blades can dissipate heat from the main body of the electric energy meter. When the external air is humid, the air will pass through the S-shaped guide plate. When the humid air passes through the S-shaped guide plate, the dehumidification block will absorb the moisture in the air, thereby reducing the mildew and corrosion caused by moisture inside the main body of the electric energy meter. At the same time, through the cooperation of the rotating column, the scraper rod and the dehumidification block, the rotation of the scraper rod will contact the surface of the dehumidification block, so that the surface of the dehumidification block becomes hardened, thereby maintaining the effective moisture absorption capacity of the dehumidification block and ensuring that the dehumidification block continues to effectively remove moisture from the air. At the same time, the rotation of the scraper rod will also accelerate the flow of air absorbed as moisture. BRIEF DESCRIPTION OF THE DRAWINGS

The arc plate 1103 is located on the displacement trajectory of the cleaning roller 1008. Through the setting of the above structure, the arc plate 1103 will be resisted by the L-shaped plate 1010 and cannot rotate upward, so the arc plate 1103 will scrape off the dust or impurities on the surface of the cleaning roller 1008, thereby avoiding the cleaning roller 1008 from bringing dust or impurities to the surface of the glass cover 3 of the electric energy meter display screen again, thereby preventing the surface of the glass cover 3 from being contaminated again.

[0031] The bottom of the threaded rod 1003 is fixedly connected with a connecting rod 1105, the circumferential surface of the connecting rod 1105 penetrates and rotates on the bottom of the limit block 1005, the bottom of the connecting rod 1105 is fixedly connected with a turntable 1106, the circumferential surface of the turntable 1106 is fixedly connected with a plurality of protrusions 1107, the bottom of the collection box 1101 is fixedly connected with a connecting block 1108, the fixed sliding connection of the connecting block 1108 is connected with a Z-shaped block 1109, and the Z-shaped block 1109 is fixedly connected with a Z-shaped block 1109.

A plurality of knocking blocks 1118 are fixedly connected to the top of the connecting plate 1117. A protrusion four 1119 is fixedly connected to the top of the connecting plate 1117. The protrusion two 1110 is located on the displacement trajectory of the plurality of protrusion one 1107. The protrusion four 1119 is located on the displacement trajectory of the protrusion three 1113. The collecting box 1101 is in contact with the plurality of knocking blocks 1118. Through the arrangement of the above structure, the collecting box 1101 vibrates, and the vibration of the collecting box 1101 will cause the short rod 1102 and the arc plate 1103 to vibrate. The vibration of the arc plate 1103 will cause the dust or impurities scraped off the cleaning roller 1008 to fall into the collecting box 1101, so as to prevent the arc plate 1103 from accumulating the dust or impurities scraped off the cleaning roller 1008 on the arc plate 1103, resulting in the problem of dust or impurities contaminating the cleaning roller 1008.

[0032] When in use, the two L-shaped clamping blocks 8 are placed on the upper and lower sides of the guide rail, and the bidirectional threaded rod 6 is driven to rotate by turning the handle 7 to reduce the height of the two L-shaped clamping blocks 8 and clamp the guide rail.

The problem of blocking the glass cover 3 of the electric energy meter display screen is solved, thereby improving the clarity of the display screen and making the reading more accurate and easy to view; at the same time, the movement of the cleaning roller 1008 will drive the arc block 1012 to move, and the movement of the arc block 1012 will conflict with the arc block 1011, so that the arc block 1012 moves away from the arc block 1011, and the movement of the arc block 1012 will cause the cleaning roller 1008 to move along the surface of the long rod 1007, and the cleaning roller 1008 squeezes the spring 1009, when the movement of the arc block 1012 does not conflict with the arc block 1011, the spring 1009 will drive the cleaning roller 1008 and the arc block 1012 to reset through its own elastic force, and so on, so that the cleaning roller 1008 can realize reciprocating motion, and the reciprocating motion of the cleaning roller 1008 can enhance the cleaning effect of dust or impurities on the surface of the glass cover 3.

[0033] When the cleaning roller 1008 moves to the upper part of the collecting box 1101, the cleaning roller 1008 will hit the arc plate 1103, so that the arc plate 1103 will drive the short rod 1102 to rotate downward. When the cleaning roller 1008 continues to move to the inside of the collecting box 1101, the cleaning roller 1008 will not hit the arc plate 1103, so the arc plate 1103 will be reset by the elastic force of the torsion spring 1104. When the cleaning roller 1008 is about to leave the collecting box 1101, the cleaning roller 1008 will hit the arc plate 1103 again, and the arc plate 1103 will be unable to rotate upward due to the resistance of the L-shaped plate 1010.
