In addition, if there are terms such as "first", "second", etc., they are also used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] This embodiment relates to a transformer oil tank that is convenient for sampling. The overall structure is as follows: Figure 1 and Figure 2 As shown, it includes an oil tank 1, a reinforcement plate 2, a sampling device 3, and a sealing plate 4.

[0032] Among them, a connecting port 101 is opened at the bottom of the side wall of the oil tank 1, the reinforcing plate 2 is welded on the connecting port 101, the sampling device 3 is connected and set on the reinforcing plate 2, the sampling device 3 includes an outer shell 301, a driving disk 302 arranged at the bottom of the inner shell 301, and a pressure plate 303 arranged at the top of the inner shell 301, a conical compression spring 304 is arranged between the driving disk 302 and the pressure plate 303, a driving rod 305 is connected to the driving disk 302, the pressure plate 303 is fixedly connected to the driving rod 305, and the sealing plate 4 is fixedly arranged between the reinforcing plate 2 and the sampling device 3.

[0033] It is worth mentioning that the transformer oil tank 1 is a common transformer part in the prior art and will not be described in detail here. A reinforcing plate 2 is provided on the connecting port 101 at the bottom outer side of the oil tank 1. The connecting port 101 is not prone to deformation when the oil tank 1 is in use, thereby ensuring the service life of the oil tank 1. When the oil-immersed transformer is used for a long time, some impurities will be generated. By setting the sampling device 3, the problem of disassembling the oil outlet is avoided when sampling the oil sample, thereby ensuring the convenience of sampling the oil sample in the oil tank 1 and avoiding the problem of splashing due to excessive pressure when the oil outlet needs to be opened. By setting the sealing plate 4, oil leakage between the reinforcing plate 2 and the sampling device 3 is prevented.

[0034] As a preferred example, Figure 4 , Figure 6 , Figure 7 and Figure 8As shown, in this embodiment, three through grooves 3021 are provided on the driving disk 302, an annular groove 3022 is provided on the driving disk 302, a fixing groove 3023 is provided in the middle position of the driving disk 302, a convex plate 3024 is provided at the bottom of the driving disk 302, driving rods 3025 are symmetrically provided at both ends of the outer side of the driving disk 302, the bottom of the conical compression spring 304 is connected and provided on the annular groove 3022, the bottom of the driving rod 305 is provided on the fixing groove 3023, and the housing 301 and the driving A fixed disk 306 is arranged between the disks 302, a slide groove 3061 is arranged on the inner side wall of the fixed disk 306, a groove 3062 is arranged on the fixed disk 306, a sealing ring 3063 is arranged on the groove 3062, a through hole 3064 corresponding to the through groove 3021 is arranged on the groove 3062, and the driving rods 3025 on both sides of the driving disk 302 are arranged on the slide groove 3061, and the through groove 3021, the through hole 3064, the convex plate 3024 and the sealing ring 3063 are similar in shape.

[0035] It should be noted that the driving rod 305 is installed on the fixed groove 3023 of the driving disk 302, and the driving stick 3025 is set on the slide groove 3061 on the inner side of the fixed disk 306. By rotating the handle of the driving rod 305, the driving stick 3025 of the driving disk 302 is moved on the slide groove 3061 of the fixed disk 306, so that the driving disk 302 is rotated. The conical compression spring 304 is connected to the annular groove 3022. As the driving disk 302 rotates, when the driving stick 3025 moves to the bottom of the slide groove 3061, the convex plate 3024 at the bottom of the driving disk 302 just moves to the groove 3062 of the fixed disk 306, and corresponds to the position of the sealing ring 3063. At the same time, under the action of the conical compression spring 304, the convex plate 3024 presses and seals the sealing ring 3063.

[0036] As a preferred embodiment, Figure 6 As shown, in this embodiment, a top plate 307 is arranged between the pressing plate 303 and the housing 301, a sealing gasket 308 is arranged between the top plate 307 and the pressing plate 303, an oil outlet 3071 is arranged at the middle position on the top plate 307, an oil outlet groove 309 is arranged on the outer side of the top plate 307 away from the conical compression spring 304, and a dial plate 310 is arranged on the outer side of the top plate 307 on the housing 301. Specifically, the conical compression spring 304 is arranged between the pressing plate 303 and the driving disk 302, and under the action of the driving rod 305, the pressing plate 303, the driving disk 302 and the conical compression spring 304 rotate simultaneously. The setting of the sealing gasket 308 ensures the sealing between the top plate 307 and the pressing plate 303, further preventing the oil leakage phenomenon, and the setting of the oil outlet groove 309 has a certain guiding effect when sampling.

[0037] As a preferred embodiment, Figure 5As shown, in this embodiment, a pointer 311 is provided on the driving rod 305 outside the top plate 307, and the pointer 311 corresponds to the scale plate 310. Specifically, the cross-sectional area of ​​the communication between the through groove 3021 and the through hole 3064 is controlled by controlling the corresponding scale number on the pointer 311 and the scale plate 310.

[0038] When the pointer 311 is at the zero point of the dial 310, the driving rod 3025 is at the lowest end of the slide groove 3061. At this time, under the action of the conical compression spring 304, the convex plate 3024 of the driving disk 302 presses the sealing ring 3063 on the groove 3062, and the pressure plate 303 presses the sealing gasket 308 and the top plate 307. The conical compression spring 304 plays a bidirectional sealing role for the shell 301. By rotating the handle on the driving rod 305, the connecting cross-sectional area of ​​the driving disk 302 and the fixed disk 306 is adjusted. When the driving rod 305 rotates forward or reversely, when the scale of the pointer 311 is at +60° and -60°, the through groove 3021 and the through hole 3064 are completely connected. At this time, the connecting cross-sectional area reaches the maximum value, and the flow reaches the maximum value. When the pointer rotates from 0 to 60° or 0 to -60°, the flow gradually increases.

[0039] The sampler squeezes the pressing plate 303 to move the pressing plate 303 on the driving rod 305 , and the oil sample flows from the oil outlet 3071 to the oil outlet groove 309 for collection.

[0040] The utility model discloses a transformer oil tank that is convenient for sampling. By providing a reinforcing plate 2, it is ensured that the connection port 101 of the oil tank 1 will not be deformed. By providing a sampling device 3, it is ensured that the sampling of the transformer oil in the oil tank 1 is convenient, and the problem of splashing due to excessive pressure when the oil outlet needs to be opened is avoided.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
