Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a body positioning structure without bottom positioning. Background Technology

[0002] Conventional oil-immersed distribution transformer tanks have positioning pins at the bottom for positioning the transformer body. However, when the transformer body is being installed in the tank, the operator cannot see the positional relationship between the body support and the positioning pins due to the body's obstruction. The operator must slowly place the transformer body while groping for its position relative to the positioning pins, resulting in low assembly efficiency and a high risk of collisions during the installation process. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a bottomless positioning structure for the vessel body to solve one or more problems in the prior art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A bottomless positioning structure for vessel body includes multiple positioning components, which are respectively disposed on both sides of the vessel body. Each positioning component includes a fixing rod and a base. The fixing rod is fixed to the vessel body and is used to connect the corresponding base. The end of the base away from the vessel body is chamfered.

[0006] Furthermore, the base is provided with an internal thread, and the end of the fixing rod is provided with an external thread, and the base is threadedly connected to the fixing rod.

[0007] Furthermore, multiple positioning components are symmetrically arranged on both sides of the device body, and the two symmetrical fixing rods are the two ends of the same screw, and both ends of the screw are provided with locking components to fasten the device body.

[0008] Furthermore, the locking component includes a flat washer, a thick nut, and a thin nut, which are installed sequentially onto the corresponding fixing rods in order of distance from the device body from the nearest to the farthest point.

[0009] Furthermore, a stepped through hole is provided at the end of the base near the body, wherein the hole with a larger diameter is a through hole and the hole with a smaller diameter is a threaded hole, and the threaded hole is located on the side of the through hole away from the body. The depth of the through hole is greater than the total thickness of the locking component on the fixing rod.

[0010] Furthermore, the base is made of laminated wood or cast from epoxy resin.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0012] 1. The bottom positioning pins of the enclosure have been eliminated. When the device body is placed into the enclosure, it slides down the bottom of the enclosure with the help of the bottom feet for assembly, which increases the efficiency of the device body assembly.

[0013] 2. The positioning structure provides insulation protection for the end of the side screw, reducing the probability of discharge from the side screw. Attached Figure Description

[0019] A bottomless positioning body 3-positioning structure, see [reference] Figure 1 It includes multiple positioning components located at the bottom of the vessel body 3, with each positioning component positioned on one side of the vessel body 3. Each positioning component includes a fixing rod 1 and a base foot 2. The fixing rod 1 is fixed to the vessel body 3 and extends horizontally away from the vessel body 3 to connect to the corresponding base foot 2. The end of the base foot 2 away from the vessel body 3 is chamfered. The base foot 2 is made of laminated wood or cast from epoxy resin.

[0020] During the tank insertion process, since the base foot 2 is located on the outside of the tank body 3, it is easier for the base foot 2 to contact the side wall of the tank. The chamfered end of the base foot 2 can both reduce the collision with the side wall of the tank and guide the tank body 3 into the tank, allowing the tank body 3 to be inserted into the tank quickly. After installation, the inner side of the base foot 2 is close to the outer wall of the tank body 3, and the outer side of the base foot 2 is close to the inner wall of the bottom of the tank, thereby achieving positioning of the tank body 3 in the short axis direction.

[0021] The optimal application of the positioning structure in an oil tank is a stepped oil tank 4 with a cross-section that is wider at the top and narrower at the bottom. This narrower bottom reduces the amount of transformer oil used and lowers the requirement for the length of the fixing rod 1. Of course, the positioning structure can also be applied to rectangular oil tanks by increasing the length of the fixing rod 1 according to the width of the oil tank. In this embodiment, as... Figure 2As shown, the device body 3 is placed into the stepped oil tank 4 to demonstrate how the two are positioned by a positioning structure.

[0022] See Figure 2 Multiple fixing rods 1 are symmetrically arranged on both sides of the device body 3, and two symmetrical fixing rods 1 are the two ends of the same screw. Both ends of the screw are provided with locking elements to secure the device body 3. The device body 3 includes an iron core, two clamps respectively clamped on both sides of the iron core, and a side screw for tightening the two clamps. In this embodiment, the side screw is the screw that forms the fixing rod 1, thus eliminating the need for an additional screw and reducing production costs. Furthermore, the base 2 provides insulation protection for the ends of the side screw, reducing the probability of discharge from the side screw.

[0023] See Figure 3 The base foot 2 has a stepped through hole near the end of the body 3. The larger diameter hole is a through hole 21, and the smaller diameter hole is a threaded hole 22. The threaded hole 22 is located on the side of the through hole 21 away from the body 3. The locking component is located in the through hole 21 of the corresponding base foot 2. The depth of the through hole 21 is greater than the total thickness of the locking component on the fixing rod 1 to ensure that the inner end face of the base foot 2 is in complete contact with the body 3 after tightening. The inner wall of the threaded hole 22 has an internal thread that mates with the fixing rod 1. The length of the fixing rod 1 outside the body 3 must be greater than the length of the through hole 21 but less than the total length of the through hole. To ensure that the base foot 2 does not fall during lifting, the length of the threaded connection between the fixing rod 1 and the threaded hole 22 should be no less than 4 threads. The locking component includes a flat washer 5, a thick nut 6, and a thin nut 7. The flat washer 5, the thick nut 6, and the thin nut 7 are installed on the screw rod in order from closest to furthest from the body 3.

[0024] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0025] 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 the 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.
