The C-shaped steel strip comprises a bottom plate and upper and lower end plates 71 and 72 arranged on the upper and lower sides of the bottom plate. A plurality of through holes 62 corresponding to the mounting columns 5 are provided on the bottom plate of the C-shaped steel strip 61. The number, position and aperture of the through holes 62 correspond to those of the threaded holes 51 on the mounting columns 5. The through holes 62 are preferably strip-shaped through holes, which facilitate adjustment of the mounting position of the mounting seat 6 to absorb the reasonable position error between the oil drain valve protection cover 2 and the oil drain valve 11.

[0033] The left and right sides between the upper end plate 71 and the lower end plate 72 in the C-shaped steel strip 61 are fixedly provided with the baffle one 63 and the baffle two 64, a gap 65 is left between the baffle one 63 and the baffle two 64, the plurality of through holes 62 are opposite to and located in the gap 65, and the distance between the inner side surface of the baffle one 63 and the bottom plate of the C-shaped steel strip 61 is equal to the distance between the inner side surface of the baffle two 64 and the bottom plate of the C-shaped steel strip 61.

[0034] The mounting seat 6 is threadedly matched with the corresponding mounting column 5 through the through hole 62 and the threaded hole 51, the bolt 7 is screwed into the threaded hole 51 through the through hole 62, so that the mounting seat 6 is fixed on the outer wall surface of the side wall of the transformer oil tank 1, since the mounting seat 6 is fixedly connected with the protective cover 60, the protective cover is synchronously fixed on the outer wall surface of the side wall of the transformer oil tank 1 through the mounting seat 6, and the drain valve protective cover 2 is fixed on the outer wall surface of the transformer oil tank 1 and covers the drain valve 11.

[0035] The outer side of the through hole 62 is provided with the gasket 8, and the gasket 8 is sleeved on the screw rod of the corresponding bolt 7, so that the pressure of the bolt 7 can be uniformly applied to the mounting seat 6, and the strip-shaped through hole and the gasket facilitate the installation of the mounting seat through the bolt.

[0036] The side, away from the baffle two 64, of the baffle one 63 is provided with the extension plate 66, the extension plate 66 is an integral structure with the baffle one 63, and the extension plate 66 is provided with the lock hole one 67 penetrating through the extension plate 66.

[0037] The lock piece 3 is a strip-shaped piece, the lock piece 3 slides in the mounting seat 6, the lock piece 3 is inserted in the inner sides of the baffle one 63 and the baffle two 64, after the lock piece 3 is inserted in the mounting seat 6, the lock piece 3 blocks the gap 65, the lock piece 3 is provided with the lock hole two penetrating through, and the lock piece 3 is locked through the padlock 4 after the lock hole one 67 and the lock hole two are aligned.

[0038] Preferably, when the lock piece 3 is inserted in the inner sides of the baffle one 63 and the baffle two 64, the inner side surfaces of the lock piece 3 respectively contact the outer end surfaces of the two bolts 7, and the outer side surfaces of the lock piece 3 respectively contact the inner side surfaces of the baffle one 63 and the baffle two 64, so that the lock piece 3 is easy to install and use, and in other embodiments, the upper end plate 71 and the lower end plate 72 are provided with sliding grooves for the lock piece 3 to slide.

[0039] The bottom end surface of the drain valve protective cover 2 is provided with a plurality of through holes 21 for discharging the overflow oil of the drain valve 11, and the drain valve protective cover 2 is not easy to accumulate water and oil.

[0040] After fixing the drain valve protective cover 2 to the transformer tank 1 with bolts, the locking plate 3 is inserted into the mounting base 6 and locked by the padlock 4. This can prevent theft of the drain valve 11, which is directly installed on the outer wall of the transformer tank. In addition, the structure of the transformer drain valve 11 anti-theft device is simple and reasonable. This not only reduces the production cost of the anti-theft device, but also has good applicability. The drain valve 11 protective cover, together with the mounting column and mounting base structure, makes the transformer drain valve 11 anti-theft device applicable to drain valves 11 of different sizes.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
