Description

Technical Field

[0001] The invention relates to the technical field of electric power meters, and in particular to a shatterproof electric power meter for electric power automation equipment. Background Art

[0002] An electricity meter is a device used to measure electrical energy consumption. It is usually installed in the switchboard of a home or commercial building. It can record parameters such as current, voltage and power passing through it, and calculate the total amount of electrical energy consumed from these data.

[0003] Electricity meters need to be installed separately in electric power automation equipment to monitor it. The electricity meters on some electric power automation equipment are installed on the outside. When these equipment are moved and used, the electricity meters may be subject to some collisions. The transparent cover used for observation on the front of the electricity meter is relatively fragile and is likely to be broken or damaged after a collision, which greatly affects the normal use of the electricity meter. Based on these problems, Chinese patent CN221224833U discloses a shatterproof electricity meter for electric power automation equipment. The protective cover completely covers the outside of the electricity meter body, and cooperates with a fixed frame and a transparent protective plate to fully protect the transparent cover on the electricity meter body. When it is hit by external force, the buffer spring can play a buffering role and reduce the impact force of the external force on the electricity meter body. At the same time, the transparent protective plate can further prevent external objects from colliding with the electricity meter body, thereby avoiding the transparent cover on the electricity meter body from breaking.

[0004] Firstly, the buffer spring in the electricity meter is exposed to the air, so a lot of dust and water stains are easily attached to the surface, which causes rust on the surface of the buffer spring, which not only affects the normal expansion and contraction of the buffer spring, but also reduces the buffering effect of the protective cover. Secondly, after the cleaning rod in the electricity meter cleans the surface of the transparent protective plate, the cleaned dust can easily fall into the slide groove of the inner wall of the protective cover, which not only affects the normal sliding of the cleaning rod, but also reduces the service life of the protective structure.

When the protective frame is pressed toward the front end surface of the protective shell, the triangular block on the plug block contacts the shell wall of the protective shell and slides toward the inner wall of the protective shell. At this time, the plastic gasket on the plug block will bend. When the triangular block moves to the plug frame position, the triangular block on the plug block will directly insert into the inner wall of the plug frame, thereby fixing the protective frame. When the two sets of extrusion blocks move in opposite directions, the two sets of extrusion plates will also move in opposite directions. At this time, the extrusion plate will directly push out the plug block inserted into the plug frame, and then the protective frame can be disassembled, which also facilitates the replacement of the transparent protective cover.

[0019] (4) The cleaning brush can be fixed on the U-shaped sliding frame by utilizing the connection structure between the nut, the second threaded shaft and the U-shaped sliding frame. After the nut is removed, the cleaning brush can be removed. BRIEF DESCRIPTION OF THE DRAWINGS
