[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In embodiment 1, the utility model provides Figure 1-Figure 6 The illustrated embodiment is a groove-type reinforcing iron structure for a large transformer oil tank, comprising an oil tank 3, on the surface of which are mounted transverse groove-type reinforcing iron 1 and vertical groove-type reinforcing iron 2. Figure 1 FIG. 2 is a schematic diagram of the installation structure of the horizontal groove reinforcing iron 1 and the vertical groove reinforcing iron 2. The horizontal groove reinforcing iron 1 is horizontally installed between two vertical vertical groove reinforcing irons 2. Since the corners of the vertical groove reinforcing iron 2 are provided with arc chamfers 201, in the prior art, when the horizontal groove reinforcing iron 1 and the vertical groove reinforcing iron 2 are welded, the weld bead 210 formed between the horizontal groove reinforcing iron 1 and the arc chamfers 201 is relatively large (reference Figure 4 and Figure 5 ), the welding process has a large workload, resulting in a great waste of welding materials, great difficulty in processing, and time-consuming and material-consuming. Therefore, in the utility model, overlapping extension sections 101 are integrally provided at both end portions of the transverse groove-type reinforcing iron 1, and the overlapping extension sections 101 extend into the weld bead 210. The weld bead 210 is overlapped by using the overlapping extension sections 101 to reduce the weld bead 210, the welding process is simple, the structure is beautiful, the welding process workload is greatly reduced, working hours are saved, and production is convenient.

[0027] Furthermore, due to the welding between the transverse groove type reinforcement iron 1 and the vertical groove type reinforcement iron 2, the solder is welded into the weld bead 210, and the solder forms an integrated structure in the weld bead 210 that is engaged between the overlapping extension section 101 and the arc chamfer 201, which will increase the fixing strength between the transverse groove type reinforcement iron 1 and the vertical groove type reinforcement iron 2. That is, by setting the overlapping extension section 101, the welding workload can be reduced, and the connection strength between the transverse groove type reinforcement iron 1 and the vertical groove type reinforcement iron 2 can also be increased.

[0028] In embodiment 2, the utility model provides Figure 7-Figure 9 The shown embodiment is a groove-type reinforcing iron structure for a large transformer oil tank, in which the transverse groove-type reinforcing iron 1 and the vertical groove-type reinforcing iron 2 are fixedly connected to the oil tank 3 by long screws 4. The transverse groove-type reinforcing iron 1 and the vertical groove-type reinforcing iron 2 are detachably arranged, which can not only ensure the strength of the oil tank 3, but also facilitate the separate replacement of the transverse groove-type reinforcing iron 1 and the vertical groove-type reinforcing iron 2, thereby reducing the use cost. When the transverse groove-type reinforcing iron 1 and the vertical groove-type reinforcing iron 2 are severely worn and cannot be used, they can be replaced separately.

[0029] Considering that the detachable transverse groove type reinforcement iron 1 and the vertical groove type reinforcement iron 2 are convenient to replace, if the transverse groove type reinforcement iron 1 and the vertical groove type reinforcement iron 2 are not sufficiently fitted to the surface of the fuel tank 3, a stress concentration distribution phenomenon will be formed, which will aggravate the wear of the transverse groove type reinforcement iron 1 and the vertical groove type reinforcement iron 2. Therefore, the side of the transverse groove type reinforcement iron 1 and the vertical groove type reinforcement iron 2 fitted to the fuel tank 3 are both arc-shaped convex surfaces, and a rubber pad 7 is fixedly arranged on the arc-shaped convex surface; when the transverse groove type reinforcement iron 1 and the vertical groove type reinforcement iron 2 are fitted on the fuel tank 3, since the rubber pad 7 can be elastically deformed, the rubber pad 7 is located on the arc-shaped convex surface. The middle part first contacts with the surface of the fuel tank 3. When the transverse groove type reinforcing iron 1 and the vertical groove type reinforcing iron 2 are parallelly fitted on the side of the fuel tank 3, the air between the transverse groove type reinforcing iron 1, the vertical groove type reinforcing iron 2 and the fuel tank 3 can be squeezed out through the elastically deformable rubber pad 7, thereby ensuring a good fit between the transverse groove type reinforcing iron 1, the vertical groove type reinforcing iron 2 and the fuel tank 3. When external force acts on the transverse groove type reinforcing iron 1 or the vertical groove type reinforcing iron 2, the stress can act evenly on the surface of the fuel tank 3 without forming a stress concentration distribution phenomenon. In addition, the rubber pad 7 can be elastically deformed and has a certain buffering and protective effect.

[0030] In order to further increase the service life of the transverse groove type reinforcing iron 1 and the vertical groove type reinforcing iron 2, a groove 5 is provided on the side of the transverse groove type reinforcing iron 1 and the vertical groove type reinforcing iron 2 away from the oil tank 3, and a reinforcing iron block 6 is telescopically arranged in the groove 5. The reinforcing iron block 6 is connected to an elastic component on the side close to the oil tank 3. The reinforcing iron block 6 replaces the transverse groove type reinforcing iron 1 and the vertical groove type reinforcing iron 2 to contact with external objects. When the reinforcing iron block 6 is subjected to force, it shrinks into the groove 5. When the reinforcing iron block 6 shrinks into the groove 5, it compresses the elastic component, thereby reducing the effect of external force, increasing the service life of the transverse groove type reinforcing iron 1 and the vertical groove type reinforcing iron 2, and can achieve the purpose of good buffering protection.

[0031] It should be noted that a sealing groove is provided on the groove wall of the groove 5, and a rubber sealing ring 10 is fixedly provided in the sealing groove, and the rubber sealing ring 10 is sealed between the groove wall of the groove 5 and the outer periphery of the reinforcing iron block 6; a sealed air cavity is formed between the bottom of the reinforcing iron block 6 and the bottom surface of the groove 5, and the air cavity will be compressed when the reinforcing iron block 6 shrinks into the groove 5, and the air cavity will prevent the reinforcing iron block 6 from excessive shrinkage, thereby taking into account both cushioning and stability.

[0032] The elastic component in the utility model includes a spring 9 and a magnetic suction block 8, both ends of the spring 9 are fixedly provided with a magnetic suction block 8, one of the magnetic suction blocks 8 is fixedly connected to the side of the reinforcing iron block 6 extending into the groove 5, and the other magnetic suction block 8 is movably fitted to the bottom surface of the groove 5, and the magnetic suction block 8 and the bottom surface of the groove 5 are attracted to each other. The magnetic suction block 8 and the spring 9 are simple and convenient to install, and the magnetic suction block 8 is adsorbed and fixed to the bottom surface of the groove 5, which is convenient for fixing and disassembly, and is convenient for use and maintenance.
