[0039] Please refer to the attached Figures 1-6 , which shows an oil sampling device provided by an embodiment of the present application, including: a transparent housing 1, a silicone hose 4, and a sampling bottle 6.
[0040] A manhole 2 is provided on the side of the transparent housing 1. Generally, two manholes 2 are designed (operators can operate with both hands). A rubber glove is fixedly connected to the edge of the manhole 2. The edge of the mouth of the rubber glove is fixedly connected to the edge of the manhole 2. The rubber glove is made of a flexible material. The user inserts both hands into the rubber glove outside the transparent housing 1 and then operates inside the transparent housing 1. A sampling hole 3 is provided at the top of the transparent housing 1. The sampling hole 3 corresponds to the sampling bottle 6. The silicone hose 4 is fixedly connected to the transparent housing 1. The first end of the silicone hose 4 is located outside the transparent housing 1, and the second end of the silicone hose 4 is located inside the transparent housing 1. A plug plate 5 is fixedly connected to the outside of the second end of the silicone hose 4. The plug plate 5 is an annular member, and its size is such that it can block the bottom port of the sampling bottle 6.
[0041] As Figure 5 shown in, the sampling bottle 6 includes a bottle body 601. The bottom port of the bottle body 601 corresponds to the sampling hole 3, so that the bottom port of the bottle body 601 can be inserted into the sampling hole 3. An annular inner support 602 is installed on the inner side of the bottle body 601 by screw threads, and a cover body 603 is installed on the bottom port of the bottle body 601 by screw threads.
[0042] The steps of the sampling operation are as follows:
[0043] Step 1: First, open the corresponding sampling valve (the sampling valve below the oil tank or the sampling valve on the side of the transformer oil), let the transformer oil drain out for a period of time (the drained transformer oil can flow into the transparent housing 1 from the sampling hole 3), then connect the first end of the silica gel hose 4 to the transformer oil outlet so that the transformer oil can enter the inside of the silica gel hose 4 and rinse the silica gel hose 4 once.
[0044] Step 2: Invert and install the sampling bottle 6 at the sampling hole 3 (at this time, the annular inner support 602 and the cover 603 of the sampling bottle 6 are in a disassembled state). Align the second end of the silica gel hose 4 with the bottom port of the sampling bottle 6 and rinse the inside of the sampling bottle 6 several times. Then, send the annular inner support 602 and the cover 603 into the inside of the transparent housing 1 from the sampling hole 3 and rinse them with the transformer oil discharged from the second end of the silica gel hose 4.
[0045] Step 3: Install the annular inner support 602 inside the transparent housing 1. Align the second end of the silica gel hose 4 with the bottom port of the sampling bottle 6, and use the plug plate 5 to block the bottom port of the sampling bottle 6. Fill the inside of the bottle body 601 with transformer oil. After filling, remove the plug plate 5. All the transformer oil in the inner area of the annular inner support 602 flows downward, and the transformer oil in the local area outside the annular inner support 602 and inside the bottle body 601 is the sampled transformer oil. Then, threadedly install the cover 603. The operator removes the sampling bottle 6 from above the transparent housing 1 and cleans the transformer oil at the port of the sampling bottle 6 to complete the sampling operation.
[0046] As Figure 4 shown in, in one embodiment, the transparent housing 1 includes: an upper cover 101 and a base 102. The bottom end of the upper cover 101 is open. The upper cover 101 is made of food-grade transparent insulating resin, which is easy to clean, and the transparent material is easy to observe the situation inside the upper cover 101. The base 102 is fixedly installed at the bottom opening of the upper cover 101, and a collection area for storing contaminated oil is provided on the base 102.
[0047] The transformer oil flowing into the inside of the transparent housing 1 is centrally collected in the collection area for storing contaminated oil provided on the base 102. After disassembling the upper cover 101 and the base 102, the transformer oil in the collection area for storing contaminated oil can be quickly taken out.
[0048] As Figure 6 shown in, in one embodiment, the base 102 includes: a trough body 102a, a bottom plate 102b, and a filter element 102c.
[0049] A pollution oil collection pool is provided at the top of the tank body 102a. The pollution oil collection pool is used to centrally collect the transformer oil during the flushing process. A filter member 102c is fixedly connected to the inner side of the pollution oil collection pool. The filter member 102c is composed of a plurality of rod-shaped metal parts. When in use, it can prevent the annular inner support 602 and the cover body 603 from falling into the tank body 102a. The bottom plate 102b is fixedly installed at the bottom of the tank body 102a. The tank body 102a can be inserted into the bottom port of the upper cover 101, and the bottom plate 102b serves as a support plate.
[0050] In one embodiment, in order to stably fix the bottle body 601, the bottom port of the bottle body 601 is threadedly engaged with the sampling hole 3, that is, an internal thread is provided inside the sampling hole 3, and an external thread is provided outside the bottom port of the bottle body 601, and the two can be threadedly engaged.
[0051] In one embodiment, in order to increase the sampling capacity, the annular inner support 602 is designed as a cylindrical structure with a smaller upper part and a larger lower part. The upper part of the annular inner support 602 is designed to be smaller, so the space of the annular area inside the bottle body 601 outside it will increase. The lower part of the annular inner support 602 is designed to be larger to cooperate with the bottom port of the bottle body 601. That is, an internal thread is provided inside the bottom port of the bottle body 601, and an external thread is provided outside the bottom of the annular inner support 602, and the two can be threadedly engaged.
[0052] In one embodiment, the cover body 603 is threadedly installed inside the bottom port of the bottle body 601.
[0053] After considering the specification and practicing the disclosure of the present utility model, those skilled in the art will easily think of other implementation schemes of the present utility model. This application aims to cover any variations, uses or adaptation changes of the present utility model. These variations, uses or adaptation changes follow the general principles of the present utility model and include the common general knowledge or conventional technical means in the technical field not disclosed by the present utility model.
