Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a portable outdoor transformer. Background Art

[0002] The outdoor transformer is one of the important equipment in the power system. Its main function is to increase or decrease the voltage of the transmitted power to meet the needs of power transmission and distribution. In the power transmission system, due to the existence of factors such as voltage loss and cable resistance loss, the voltage needs to be increased to minimize the current loss. In the distribution system, the voltage needs to be reduced to meet different power load requirements. Therefore, the role of the outdoor transformer is to increase or decrease the voltage of the transmitted power to meet the needs of power transmission and distribution.

[0003] Due to the heavy weight of existing outdoor transformers, corresponding auxiliary tools are needed to move the outdoor transformers during transportation and installation. Before moving the outdoor transformer, workers first lift the transformer onto the auxiliary tools, and then move it to the designated location. After that, workers remove the auxiliary tools from the outdoor transformer. The whole process is very time-consuming and labor-intensive, and the operation is troublesome.

[0004] In the patent document with publication number CN207572171U, a large outdoor transformer that is easy to move is disclosed. Through the use of a rotating shaft, a threaded rod and a threaded sleeve, a rotating handle is rotated. The rotating handle drives the threaded sleeve to rotate through an active bevel gear and a driven bevel gear. The rotating threaded sleeve forces the threaded rod to rotate and generates a lifting movement on the inner side of the threaded sleeve. When the threaded rod is lifted, it can drive the lifting block and the roller to move up and down through the connecting block, the connecting rod and the hinge block. When the roller descends a certain distance, it can support the bottom of the transformer casing and leave the ground, so that the transformer can be pushed.

[0005] However, the large outdoor transformer that is easy to move is mainly pressed by the rollers after extending out of the rollers, and the pressure-bearing part of the entire box is not strong enough during movement, which easily leads to damage of the universal wheels. Therefore, it is necessary to develop an outdoor transformer that is easy to move and has easy storage of universal wheels. Utility Model Content

[0039] In actual application, the electric power of the outdoor transformer of the present application usually does not exceed 10000W.

[0040] Working principle:

[0041] Firstly, the position of the transformer box 1 can be moved conveniently and quickly through the provided moving mechanism. Since the universal wheel 202 provided inside the first universal wheel mounting seat 2 has a three-wheel structure, it can pass through outdoor roads with many obstacles more easily, thus bringing convenience to the movement of the outdoor transformer box 1.

[0042] Furthermore, after the transformer box 1 is moved to a suitable position, the rotation of the screw rod 312 can be controlled by rotating the rotating nut 313 with a wrench or by inserting a rod into the through hole opened in the auxiliary part 314, so that the screw rod mounting plate 1 304 and the screw rod mounting plate 2 315 move inward toward each other, and the lifting rod 1 301, the lifting rod 2 303, the lifting rod 3 306 and the lifting rod 4 308 move crosswise, thereby raising the base 3, and then the universal wheel 202 can be folded to lower the base 3 to complete the fixation of the transformer box 1.

[0043] Furthermore, a limit plate 205 is provided at the moving mechanism, and the control handle 208 can be pulled open to control the control rod 207 to compress the spring 210, so that the limit plate 205 moves inward. When the limit plate 205 is completely moved away from the bottom of the mounting plate 203, the universal wheel 202 can be rotated around the rotation axis 204 and fall down; after releasing the control handle 208, under the action of the restoring force of the spring 210, the limit plate 205 rebounds and limits the mounting plate 203 again. At this time, the limit plate 205 serves to fix the universal wheel 202.
