[0016] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] The present invention provides Figure 1 to Figure 4 A new type of flexible DC transformer is shown, including a transformer body 1, and the transformer body 1 is a flexible DC transformer. The valve side lead of the transformer body 1 can be led out from the vertical box cover at the end, and the grid side lead and the valve side lead are placed on one side, which solves the problem of small transportation size of the flexible DC converter transformer; at the same time, by leading the valve side lead from the box cover, the space can be effectively saved while ensuring the air distance between the live parts of each part and between the ground. The grid side lead and the valve side lead are existing common technologies and are not described in detail here. They can be adjusted according to specific usage conditions.

[0018] A support plate 2 is fixedly connected to the bottom of the transformer body 1. Two support plates 2 are provided. The two support plates 2 are respectively distributed on both sides of the bottom of the transformer body 1. A side plate 3 is fixedly connected to the support plate 2. Two side plates 3 are provided. The two side plates 3 are respectively distributed at both ends of the support plate 2.

[0019] In order to facilitate the movement of the transformer body 1, a groove 4 is provided at one end of the side plate 3 away from the support plate 2, a threaded rod 5 is provided inside the groove 4, and a moving assembly for moving the transformer body 1 is provided at the bottom of the threaded rod 5, the moving assembly includes a U-shaped frame 8, a rotating shaft 9 and a roller 10, the U-shaped frame 8 is rotatably connected to the bottom end of the threaded rod 5, the rotating shaft 9 is fixedly connected to the U-shaped frame 8, and the roller 10 is rotatably connected to the rotating shaft 9. Since the U-shaped frame 8 is rotatably arranged at the bottom end of the threaded rod 5, and the roller 10 is rotatably connected to the rotating shaft 9, a multi-directional walking effect can be achieved.

[0020] In order to fix the position of the threaded rod 5 , a first threaded sleeve 6 is threadedly connected to the threaded rod 5 , and the first threaded sleeve 6 is located above the side plate 3 . A second threaded sleeve 7 is threadedly connected to the threaded rod 5 , and the second threaded sleeve 7 is located below the side plate 3 .

[0021] Before installing the transformer body 1, rotate the second threaded sleeve 7 so that the second threaded sleeve 7 is at a suitable height position on the threaded rod 5, and there is a certain distance between the first threaded sleeve 6 and the second threaded sleeve 7, which is greater than the thickness of the side plate 3; then insert the threaded rod 5 into the groove 4, and then rotate the first threaded sleeve 6 to move the first threaded sleeve 6 downward. Through the cooperation between the first threaded sleeve 6 and the second threaded sleeve 7, the threaded rod 5 is fixed on the side plate 3, so that the movement of the transformer body 1 can be achieved by moving the assembly.

[0022] Meanwhile, in actual use, the distance between the transformer body 1 and the ground can be adjusted by rotating the first threaded sleeve 6 and the second threaded sleeve 7, thereby improving the flexibility of use.

[0023] When the transformer body 1 is installed, the threaded rod 5 together with the first threaded sleeve 6, the second threaded sleeve 7 and the moving assembly and other structures can be removed without affecting the installation of the transformer body 1, so that the first threaded sleeve 6, the second threaded sleeve 7 and the moving assembly and other structures can be reused.

[0024] By providing structures such as the threaded rod 5 and the moving assembly, the movement of the transformer body 1 is facilitated, and the distance between the transformer body 1 and the ground can be adjusted, thereby improving the flexibility of use. In addition, structures such as the first threaded sleeve 6, the second threaded sleeve 7 and the moving assembly can be reused, thereby reducing the cost of use.

[0025] In order to prevent the threaded rod 5 from running out of the end of the groove 4 away from the support plate 2, a threaded hole 11 is opened on the side wall of the side plate 3. The internal thread of the threaded hole 11 is connected with a bolt 12, and the bolt 12 cooperates with the threaded rod 5.

[0026] Before inserting the threaded rod 5 into the groove 4, remove the bolt 12; after the threaded rod 5 is inserted into the groove 4, rotate the bolt 12 so that the bolt 12 passes through the groove 4 to limit the threaded rod 5, thereby improving the stability of use.

[0027] In order to facilitate the installation of structures such as the threaded rod 5, thread grooves 13 are provided at both ends of the bottom of the support plate 2. The internal threads of the thread grooves 13 are connected to thread blocks 14, and support rods 15 are fixedly connected to the thread blocks 14. In the production stage, the operator holds the support rod 15 to connect the thread blocks 14 with the thread grooves 13, rotates the support rod 15, and completes the connection between the support rod 15 and the support plate 2. The four support plates 2 cooperate to support the transformer body 1, so that there is space for the bottom of the transformer body 1 to move with the ground, which is convenient for the subsequent lifting equipment to lift the transformer body 1 and install structures such as the threaded rod 5.

[0028] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
