The present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present invention thorough and complete, and to fully express the scope of the present invention to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, the composition of materials, numerical expressions, and values ​​set forth in these embodiments should be interpreted as merely exemplary and not as limiting.

[0021] The terms "first," "second," and similar words used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different parts. Words such as "including" or "comprising" mean that the element preceding the word encompasses the element listed after it, and do not exclude the possibility of encompassing other elements as well. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] like Figures 1 to 4 As shown, the substation relay protection device includes a main body 1. Along the centerline of the front side of the main body 1, from top to bottom, a display screen 11, indicator lights 12, and a button assembly are sequentially arranged. Two baffles 2, corresponding to the button assembly, are slidably arranged on the main body 1 in the horizontal direction. Corresponding locking posts 5 are fixedly arranged on the adjacent sides of the two baffles 2. The two locking posts 5 are semi-cylindrical structures of the same diameter. After the two baffles are closed, the two locking posts 5 are spliced ​​into a cylindrical structure. Corresponding locking holes 51 are opened radially on the two locking posts 5. Locks 7 are provided inside the locking holes 51 for detachably and fixedly connecting the two locking posts 5. In this embodiment, after the two baffles 2 are closed, they can shield the button assembly, preventing accidental button presses. At the same time, the baffles 2 do not obstruct the display screen, thus not affecting the reading of information on the display screen. The baffles are locked together by the locks 7. Only after relevant personnel open and remove the locks 7 can the button assembly be operated, preventing unauthorized personnel from opening it and improving safety.

[0023] In some embodiments, a locking ring 6 is detachably fitted on the outer side of the two locking pins 5. After the two baffles 2 are closed, the two locking pins 5 are spliced ​​into a cylindrical structure. The locking ring 6 can be fitted on the outer side of the cylindrical structure to fix the two locking pins 5 together, thereby making the two baffles 2 fit tightly together.

[0024] In some embodiments, the inner side of the locking ring 6 is provided with an internal thread, and the outer side of the two locking pins 5 is provided with an external thread that matches the internal thread. After the two baffles 2 are closed, the two locking pins 5 are spliced ​​into a cylindrical structure. The locking ring 6 is assembled together by the internal thread inside it and the external thread outside the locking pin 5, so that the two baffles 2 fit tightly together.

[0025] In some embodiments, as a specific implementation of the sliding connection between the baffle 2 and the body 1, the upper end of the baffle 2 is provided with symmetrically arranged grooves 4 on the inner sides of both ends, and the front side of the body 1 is provided with a slide rail 3 that matches the grooves 4. The grooves 4 and the slide rail 3 are slidably connected. The grooves 4 are strip structures with an "L"-shaped cross section that are integral with the baffle 2, and the slide rail 3 is a strip structure with an "L"-shaped cross section that is integral with the front side of the body 1. The grooves 4 and the slide rail 3 are slidably connected together.

[0026] In some embodiments, both the upper and lower ends of the baffle 2 are provided with strip-shaped sliding holes 21 corresponding to the slide rail 3. A slide rod 31 is slidably arranged inside the strip-shaped sliding hole 21. One end of the slide rod 31 is fixedly connected to the slide rail 3, and the other end of the slide rod 31 is fixedly provided with a baffle plate 32. The slide rod 31 is slidably connected to the strip-shaped sliding hole 21. The slide rod 31 can only slide within the range of the strip-shaped sliding hole 21, thereby limiting the sliding range of the baffle 2.

[0027] In some embodiments, such as Figure 4 As shown, a first rack 22 is fixedly installed at the bottom of one baffle 2 in the horizontal direction, and a second rack 23 is fixedly installed at the bottom of the other baffle 2 in the horizontal direction. A gear 24 is rotatably installed at the front of the body 1 between the first rack 22 and the second rack 23. The first rack 22 and the second rack 23 are both meshed with the gear 24. When one baffle 2 moves, it is driven by the meshing of the first rack 22 or the second rack 23 at its bottom with the gear 24, which drives the second rack 23 or the first rack 22 to move synchronously, thereby driving the other baffle 2 to move, so as to realize the synchronous opening and closing of the two baffles 2.

[0028] In some embodiments, a cover 8 is fixedly provided on the front side of the main body 1, which is fitted outside the first rack 22 and the second rack 23. The cover 8 provides protection for the first rack 22, the second rack 23, and the gear 24.
