Further:

As shown in Figure 1 to Figure 4:

Combined with the above content: it also includes a protective component 2 arranged inside the cabinet door 4;

The protective component 2 includes a rectangular slot 21 opened inside the cabinet door 4 and two plug-in slots 27 opened on the surface of the cabinet door 4. The plug-in slots 27 are connected with the inside of the rectangular slot 21, and the inside of the plug-in slot 27 is inserted into the cabinet door 4. There is a U-shaped protective plate 26. The U-shaped protective plate 26 is slidingly connected to the cabinet door 4. Two optical axes 24 are symmetrically arranged inside the rectangular groove 21. The optical axis 24 is fixedly connected to the cabinet door 4. The surface of each optical axis 24 Both are provided with pull cords 23, and a connecting rod 22 is provided inside the rectangular groove 21.

In this embodiment, a force is applied to the square block 32 so that the square block 32 slides inside the communication groove 31. As the square block 32 moves downward, the movement of the square block 32 drives the connecting rod 22 to move. The connecting rod 22 moves in During the movement, the U-shaped protective plate 26 is pulled by the pull rope 23 to slide inside the insertion slot 27. As the connecting rod 22 continues to move, until the U-shaped protective plate 26 completely covers the visual glass 5, the U-shaped protective plate 26 is fixed in front of the visual glass 5 to block the visual glass 5 and solves the problem that the visual glass 5 is easily scratched and dusted, thus affecting its transparency.

It should be noted that the U-shaped protective plate 26 has a U-shaped structure, and a scraper is installed inside the U-shaped protective plate 26 to facilitate scraping off the dust adhered to the surface of the visual glass 5. The surface of the optical axis 24 is smooth, so that The pulling rope 23 reduces the generation of frictional resistance during the movement of the U-shaped protective plate 26 .

Going further:

In an optional embodiment, two connecting blocks 25 are symmetrically and fixedly connected to both sides of the U-shaped protective plate 26. Both ends of the pull rope 23 are fixedly connected to the connecting blocks 25 and the connecting rod 22 respectively. The connecting rod 22 Located below the U-shaped protective plate 26.

In this embodiment: the connecting block 25 is in contact with the inner wall surface of the cabinet door 4, so as to restrict the position of the U-shaped protective plate 26 so that the distance between the U-shaped protective plate 26 and the cabinet door 4 remains unchanged. The effect of scraping dust on the surface of visual glass 5 is guaranteed.

Going further:

In an optional embodiment, it also includes a limiting component 3 provided on the surface of the cabinet door 4;

The limiting component 3 includes a square block 32 fixedly connected to the surface of the connecting rod 22 and a communication groove 31 opened on the front surface of the cabinet door 4. The communication groove 31 is connected with the rectangular groove 21, and the square block 32 is inserted inside the communication groove 31. , and is slidingly connected to the cabinet door 4 through the communication groove 31. A spring 34 and a ball 35 are provided in the cylindrical groove 33 opened inside the square block 32. The two ends of the spring 34 are fixedly connected to the square block 32 and the ball 35 respectively. The cabinet door There are two arc-shaped grooves connected with the communication groove 31 in the interior of 4.

In this embodiment: during the movement of the square block 32, the ball 35 slides out of the arc-shaped groove at the corresponding position. At this time, the ball 35 slides into the arc-shaped groove at the corresponding position under the action of the elastic potential energy of the spring 34. The two arc-shaped grooves are provided to fix the two positions of the U-shaped protective plate 26 after it moves.

Working principle: When the center-mounted high-voltage switch cabinet is in use, the situation inside the cabinet can be seen through the visual glass 5. When the visual glass 5 needs to be protected, force is exerted on the square block 32, so that the square block 32 Sliding inside the communication groove 31, the square block 32 moves, causing the ball 35 to slide out of the arc-shaped groove at the corresponding position. As the square block 32 moves downward, the movement of the square block 32 drives the connection The rod 22 moves, and during the movement, the connecting rod 22 pulls the U-shaped protective plate 26 through the pull rope 23 to slide inside the insertion slot 27. As the connecting rod 22 continues to move, the U-shaped protective plate 26 completely covers the receptacle. Looking at the glass 5, the ball 35 at this time slides into the arc groove at the corresponding position under the action of the elastic potential energy of the spring 34, thereby fixing the moved position of the U-shaped protective plate 26, and the U-shaped protective plate 26 is fixed in a removable position. In front of the viewing glass 5, the viewing glass 5 can be blocked, which solves the problem that the viewing glass 5 is easily scratched and dusted, thereby affecting its transparency.

Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present utility model.
