Description

Technical Field

[0001] This utility model relates to the field of combined instrument transformer installation technology, specifically to a convenient mobile device for installing metering combined instrument transformers. Background Technology

[0002] With the rapid development of the global economy, electricity, as a basic energy source, is increasingly widely used in various fields. Whether it is large-scale machinery and equipment in industrial production or various electrical appliances in daily life, the dependence on electricity is constantly increasing. This has led to the continuous expansion of the power system and the increasing complexity of the power grid structure, which covers multiple voltage levels and different types of power equipment. From high-voltage transmission lines to low-voltage distribution networks, they are widely distributed in every corner of cities and villages. Against this backdrop, accurate electricity metering plays a crucial role in the effective management of electricity supply, fair trade settlement, and stable operation of the power system. Whether it is power companies collecting electricity fees from users or energy consumption accounting between different departments or production links within a company, accurate electricity data is fundamental.

[0003] Existing metering combined transformers lack convenient relocation measures during installation, making it difficult to move the heavy transformers to the designated installation location. This greatly increases installation time and labor costs. Furthermore, when metering combined transformers require maintenance or repair, the inconvenience of relocation makes it difficult for maintenance personnel to move them to a suitable maintenance site. This not only increases the complexity of maintenance but may also affect the normal operation of other equipment and prolong power outage time. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example: Refer to Figures 1 to 4 A convenient mobile device for installing a combined current transformer for metering includes a combined current transformer body 1, a support housing 2 fixedly connected to the bottom surface of the combined current transformer body 1, a mounting bracket 3 fixedly connected to the circumferential side wall of the support housing 2, and a moving mechanism. The moving mechanism includes a telescopic moving component and a guide support component. The telescopic moving component includes a threaded rod 4 rotatably connected to the inner wall of the support housing 2 via a bearing. The threaded rod 4 is rotatably connected to the side wall of the support housing 2 through a bearing. A nut 5 is threaded onto the threaded rod 4. A support plate 6 is slidably connected inside the support housing 2. Multiple casters 7 are fixedly provided on the bottom surface of the support plate 6. Multiple first guide rods 8 are fixedly connected to the bottom surface of the combined transformer body 1. The multiple first guide rods 8 are all slidably connected to the bottom surface of the support plate 6. Multiple springs 9 are fixedly connected between the upper surface of the support plate 6 and the bottom surface of the combined transformer body 1. An inclined force-bearing block 10 is fixedly connected to the upper surface of the support plate 6. An inclined push block 11 is fixedly connected to the bottom surface of the nut 5. Multiple casters 7 are located at the four corners of the bottom surface of the support plate 6. Multiple springs 9 are respectively sleeved on multiple first guide rods 8. The inclined force-bearing block 10 and the inclined push block 11 cooperate with each other, and the inclined surface of the inclined force-bearing block 10 is in contact with the inclined surface of the inclined push block 11.

[0024] The guide support assembly includes two bearing plates 12 fixedly connected to the bottom surface of the combined transformer body 1. A threaded rod 4 is rotatably connected to the side walls of the two bearing plates 12 through a bearing. Two second guide rods 13 are fixedly connected between the inner walls of the support housing 2. Guide plates 14 are slidably sleeved on the two second guide rods 13. The side walls of the two guide plates 14 are fixedly connected to the side walls of the nuts 5. The two second guide rods 13 penetrate the side walls of the two bearing plates 12. A rotating handle is fixedly connected to the side end of the threaded rod 4 for easy operation by the staff.

[0025] The working principle of this utility model is as follows: When it is necessary to change the metering combined transformer from a fixed installation position to a mobile state, the operator holds the rotating handle and rotates the threaded rod 4. As the threaded rod 4 rotates, the nut 5 moves along the axial direction of the threaded rod 4, and the inclined push block 11 on the bottom surface of the nut 5 also moves accordingly. Since the inclined push block 11 and the inclined force block 10 on the upper surface of the support plate 6 are in contact with each other, the inclined push block 11 will generate a vertical thrust on the inclined force block 10 during the movement, so that the support plate 6 overcomes the elastic force of the spring 9 and slides downward. At this time, the multiple universal wheels 7 fixed on the bottom surface of the support plate 6 gradually contact the ground. When the universal wheels 7 fully contact the ground and support the combined transformer body 1, the combined transformer body 1 is lifted, realizing the switch from a fixed state to a mobile state. The operator can push the combined transformer body 1 and use the flexible steering and movement ability of the universal wheels 7 to move the combined transformer body 1 to the required position, thereby simplifying the installation process.

[0026] After the combined current transformer body 1 moves to its destination, the operator turns the handle to reverse the threaded rod 4. The nut 5 then moves in the opposite direction along the axis of the threaded rod 4. The thrust of the inclined push block 11 on the inclined force block 10 gradually decreases. At this time, under the influence of the weight of the combined current transformer body 1 and the force of multiple springs 9, the support plate 6 moves upward, the caster 7 gradually leaves the ground, and the support housing 2 gradually contacts the ground, thus restoring the combined current transformer body 1 to its fixed installation state. During the entire movement process, the first guide rod 8 provides precise guidance for the up and down movement of the support plate 6, ensuring the straightness and stability of its movement trajectory. The second guide rod 13 and the guide plate 14 ensure the axial linear movement of the nut 5 during the rotation of the threaded rod 4, improving the movement accuracy and reliability of the entire moving mechanism.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
