The springs 17 are fixedly installed on the inner side of the middle part of the positioning rods 10 and are fixedly connected to the bottom of the top cover 4.

[0021] In this embodiment of the utility model, when the top cover 4 is lifted, the positioning rod 10 will move upward along the positioning grooves 9 at both ends of the inner side of the protective box 1, and under the action of the spring 17, it will be inserted into the groove on the surface of the positioning groove 9. By symmetrically arraying positioning slots 9 on the left and right sides of the rear end inside the protective box 1, when the top cover 4 is lifted, the lower end of the positioning rod 10 will be inserted into the positioning slots 9 at different heights, thereby fixing the height of the top cover 4 and facilitating maintenance work for maintenance personnel.

[0022] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in a preferred embodiment of the present invention, the traction structure includes a movable groove 5, a top groove 7 and a top plate 6. The movable groove 5 is symmetrically opened at the lower ends of the left and right sides of the top cover 4, and the top groove 7 is symmetrically opened at the left and right sides of the rear end of the side plate 2. A top block 8 is fixedly installed at the outer end of the top groove 7. The top plate 6 is movably hinged inside the movable groove 5 and slidably connected to the surface of the top block 8.

[0023] In this embodiment of the utility model, when in use, when maintenance is performed, the top cover 4 is lifted upward, thereby driving the top plate 6 in the movable grooves 5 on both sides to move upward, and the inner side of the lower end of the top plate 6 slides up along the top block 8 on the inner side of the top groove 7, thereby pushing the side plate 2 open to both sides. By setting up a traction structure, when the top cover 4 is opened, it will move upwards, thereby expanding the internal area of ​​the protective box 1 and facilitating maintenance work.

[0024] like Figure 4 and Figure 6 As shown, in a preferred embodiment of the present invention, the positioning rod 10 is an arc-shaped rod, and the shape and size of the positioning groove 9 are adapted to the shape and size of the lower end of the positioning rod 10.

[0025] In this embodiment of the utility model, when in use, the positioning rod 10 is made into an arc-shaped rod, and the shape and size of the positioning groove 9 are adapted to the shape and size of the lower end of the positioning rod 10. Thus, when the positioning rod 10 moves upward, it will intermittently insert into the positioning groove 9 at different heights, thereby fixing the height of the top cover 4 and reducing the impact on maintenance work.

[0026] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in a preferred embodiment of the present invention, the top block 8 is narrow at the bottom and wide at the top, the outer side of the top block 8 is set as an arc surface, and an arc-shaped groove 18 is provided.

[0027] In this embodiment of the utility model, when in use, the top block 8 is set to be narrow at the bottom and wide at the top, which facilitates ejection. The outer side of the top block 8 is set as an arc surface and an arc-shaped sliding groove 18 is provided, so that the lower end of the top plate 6 is slidably set in the arc-shaped sliding groove 18 and slides along the surface of the top block 8. When the top cover 4 is closed, the side plates 2 on both sides will be reset at the same time, so that they can re-form a whole.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment of the present invention, guide plates 13 are symmetrically arranged on the left and right sides of the side plate 2, filter blocks 14 are filled at the lower end of the guide plates 13, through holes 12 are arrayed at the upper end of the left and right sides of the side plate 2, and a wind plate 16 is fixedly installed at the bottom of the lower end of the protective box 1, with an air inlet 15 in the middle of the bottom of the wind plate 16.

[0029] In this embodiment of the utility model, when in use, the fan on the wind plate 16 is turned on, so that air enters the protective box 1 through the air inlet 15, and then exits from the bottom of the guide plate 13 through the through hole 12 and the filter block 14, taking away the internal heat. By setting the guide plate 13, the through hole 12 is protected to prevent water from entering. By setting the filter block 14, foreign objects are prevented from entering when heat dissipation is not being carried out. Note: A filter screen is set on the surface of the air inlet 15.

[0030] like Figure 2 , Figure 4 and Figure 6 As shown, in a preferred embodiment of the present invention, the bottom of the top cover 4 is hinged with a chandelier 11, and the length of the chandelier 11 is less than the gap between the positioning rods 10 on the left and right sides.

[0031] In this embodiment of the utility model, when in use, a chandelier 11 is hinged to the bottom of the top cover 4, and the length of the chandelier 11 is less than the gap between the positioning rods 10 on the left and right sides. This allows the working angle to be changed as the top cover 4 is raised, making it convenient for maintenance personnel to perform maintenance work in low light conditions.

[0032] The above embodiments of this utility model provide a power metering protection device. When maintenance is performed, the top cover 4 is lifted upward, thereby driving the top plate 6 in the movable grooves 5 on both sides to move upward. The inner side of the lower end of the top plate 6 slides and rises along the top block 8 on the inner side of the top groove 7. Since the top block 8 is narrow at the bottom and wide at the top, when it slides from bottom to top, it will push the side plate 2 open to both sides while moving upward, thereby expanding the internal area of ​​the protection box 1. At the same time, when the top cover 4 is lifted, the positioning rod 10 will move upward along the positioning grooves 9 at both ends of the inner side of the protective box 1, and under the action of the spring 17, it will be inserted into the groove on the surface of the positioning groove 9. It can be inserted into the positioning grooves 9 at different heights as the top cover 4 is lifted, thereby fixing the height of the top cover 4, which facilitates the maintenance work of maintenance personnel.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
