Description

Technical Field

[0001] This utility model belongs to the field of transformer technology, and in particular relates to a cover for a transformer oil tank. Background Technology

[0002] Transformers can be classified according to their uses as follows: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, box-type transformer test transformers, angle transformers, high-current transformers, excitation transformers, etc.

[0003] After the transformer oil tank is filled with oil, the cover needs to be fixed on top of the transformer oil tank to keep the inside of the transformer oil tank sealed. The existing transformer cover is usually installed by fixing bolts, which requires tightening multiple sets of bolts and is inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a cover for a transformer oil tank, which solves the problem that existing transformer covers are usually installed using fixing bolts, which requires tightening multiple sets of bolts and is inefficient.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a cover for a transformer oil tank, comprising a transformer oil tank body and a cover assembly. The top of the transformer oil tank body is open, and a mating plate is fixedly connected to the periphery of the top of the transformer oil tank body. The cover assembly includes a sealing oil cap and a filling block. The sealing oil cap is disposed at the top of the transformer oil tank body, and a groove is formed inside the sealing oil cap, which is adapted to the opening of the transformer oil tank body. A sealing soft sleeve is installed inside the groove, and the sealing soft sleeve is disposed inside the opening of the transformer oil tank body, forming a sealing structure with the transformer oil tank body. The filling block is disposed in the groove and slides with the groove, and the filling block is adapted to the groove. The bottom surface of the filling block is fixedly connected to the upper surface of the sealing soft sleeve. Multiple sets of connecting rods are fixedly connected to both sides of the upper surface of the filling block, and a linkage plate is fixedly connected to one end of each connecting rod. The linkage plate is disposed outside the groove. Multiple sets of positioning holes are formed on both sides of the upper surface of the sealing oil cap, and multiple sets of mating holes are formed on both sides of the upper surface of the mating plate, with the positioning holes corresponding to the mating holes.

[0007] Multiple sets of linkage pins are fixedly connected to both sides inside the linkage plate. One end of each linkage pin passes through a positioning hole and a mating hole, and has an insertion hole. Multiple sets of mating springs are installed between the linkage plate and the sealing oil cap. The mating springs are located around the linkage pins.

[0008] Both ends of the mating plate are provided with grooves. A connecting spring is provided inside the groove. A fixing rod is fixedly connected to one end of the connecting spring. One end of the fixing rod is set in the groove and slides with the groove. The other end is fixedly connected to a fixing plate. The fixing plate is set on one side of the mating plate. A connecting plate is fixedly connected to the bottom end of the fixing plate. Multiple sets of limiting rods are fixedly connected to one side of the connecting plate. One end of the limiting rod is inserted into the insertion hole.

[0009] The bottom surfaces at both ends of the mating plate are provided with sliding grooves, and both ends of the sealing oil cap are fixedly connected with mating blocks. The mating blocks are "L" shaped, and a mating slider is fixedly connected to one side of the mating block. The mating slider is set in the sliding groove and slides in cooperation with the sliding groove.

[0010] Both sides of the bottom surface of the transformer tank body are fixedly connected to the mounting base; by setting the mounting base, it is convenient to install and fix the transformer tank body.

[0011] This utility model has the following beneficial effects:

[0012] This utility model, through the setting of a sealing cap assembly, allows for the installation of the sealing oil cap. The mating blocks and sliding blocks at both ends of the sealing oil cap slide along the mating plate and groove, thereby covering the transformer tank body and aligning the positioning hole with the mating hole. Pulling the connecting plate causes the fixing plate to move the fixing rod, deforming the connecting spring and moving the limiting rod to one side. Then, pressing down the linkage plate causes the filling block to slide downwards within the slot, extending the sealing sleeve and bringing it into contact with the inner wall of the transformer tank body, forming a sealing structure and achieving a sealing effect on the transformer tank body. The linkage plate moves downwards, compressing the mating spring and causing the linkage pin to pass through the positioning hole and mating hole. Releasing the connecting plate allows the limiting rod to insert into the insertion hole of the linkage pin under the action of the connecting spring, thus limiting the linkage pin and preventing the mating spring from returning to its original position, fixing the position of the filling block, ensuring the sealing of the transformer tank body, and simultaneously fixing the position of the sealing oil cap. The installation is complete, with a simple structure, eliminating the need to tighten multiple sets of bolts, and offering high efficiency.
