Description

Technical Field

[0001] The utility model relates to the technical field of box-type transformers, in particular to a top cover structure of a box-type transformer. Background Art

[0002] When installing a box-type transformer in an outdoor environment, drainage issues need to be considered. The top cover of a conventional box-type transformer is mostly a fixed integrated structure. When the rainfall is too heavy, the accumulated water falls on the top cover, which will cause a certain amount of pressure on the top cover of the box. In severe cases, it will cause leakage in the box, affecting the normal operation and service life of the electrical components inside the box. Therefore, the box-type transformer needs to consider the drainage issue when the rainfall is too heavy. At the same time, the debris left on the top cover due to various unexpected factors will also affect the drainage efficiency. Therefore, this solution provides a box-type transformer top cover structure. Utility Model Content

[0017] An electric telescopic rod 13 is provided at the center of the top end of the top cover 2, and the top end of the electric telescopic rod 13 is fixed to the bottom surface of the top cover 5. A plurality of U-shaped grooves 10 arranged at equal intervals are provided on the left and right inclined surfaces of the top cover 5. The bottom ends of the U-shaped grooves 10 are connected to the drip pipes 11, and the bottom ends of the left and right inclined surfaces of the top cover 5 are installed with plug plates 12.

[0018] The top cover 5 is embedded and connected with the slot 7 through the plug plate 12 , and the drip pipe 11 is located outside the plug plate 12 .

[0019] The internal drainage channel of the drainage groove 9 is in an inclined shape from the center to the front and rear ends, and drainage holes 14 are provided at the front and rear ends of the drainage groove 9 .

[0020] Working principle:

[0021] In this solution, the top cover 5 is installed on the top cover 2 through an electric telescopic rod 13 and can be moved up and down. The electric telescopic rod 13 is connected to the power supply inside the box body 1 through a power cord. The front and rear end surfaces of the bottom of the top cover 5 slide up and down at the slide groove 4 through the slider 6, which plays a guiding role in the process of the top cover 2 moving up and down, and can also increase the stability of the top cover 5 assembled on the top cover 2;

[0022] The bottom ends of the inclined panels on the left and right sides of the top cover 2 are inserted and plugged into the slots 7 through the plug plates 12. When the top cover 2 moves downward, the drip pipes 11 at the bottom ends of the inclined panels on the left and right sides of the top cover 2 fall outside the slots 7 and are located at the drainage grooves 9. Rainwater sliding down from the inclined U-shaped grooves 10 on the left and right sides of the top cover 5 flows out from the bottom ends of the drip pipes 11 and falls into the drainage grooves 9. The drainage grooves 9 are all inclined from the center to the front and rear ends, so that rainwater can be discharged from the drainage holes 14 at the front and rear ends of the top cover 2.

[0023] When the top cover 2 is supported by the electric telescopic rod 13 and rises upward, the entire top cover 5 structure is lifted upward, and its plug plate 12 moves upward from the slot 7. At this time, the inclined panels on the left and right sides of the top cover 5 can be raised, and the rainwater falls on the plates on the left and right inclined surfaces of the top cover 5. Part of the rainwater splashes, and part of the rainwater slides down from the U-shaped groove 10 and flows out from the bottom end of the drip pipe 11, and will flow along the curved surface 8 to the drainage groove 9, which has the effect of increasing the discharge amount of rainwater, and also reduces the problem of excessive pressure on the top cover 2 caused by rainwater when the precipitation is too large. At the same time, it is also convenient to clean the surface of the top cover 2 after the top cover 5 is raised, and it is convenient to clean the debris between the drip pipe 11 and the drainage groove 9, so as to avoid the drainage blockage problem caused by the accumulation of debris.
