Description

Technical Field

[0001] This utility model relates to the technical field of transformer substation bottom structure, and in particular to a transformer substation bottom structure with moisture-proof and condensation-proof features. Background Technology

[0002] The bottom structure of the transformer substation is designed to prevent moisture and condensation. This structure typically achieves moisture protection through a bottom raised layer. For example, channel steel or columns are used to raise the bottom plate, forming a ventilation space separated from the ground. The sunken inner bottom plate or prefabricated space design can promote air circulation and expel moisture from the cable trench.

[0003] In existing technologies, some transformer substation bottom structures with moisture-proof and condensation-proof features a base, channel steel, or column to support the enclosure and create a ground clearance, such as a combination of a sunken inner bottom plate and a base plate. This enhances air circulation and reduces ground moisture intrusion. Ventilation holes, ventilation grilles, and blowers are installed in the bottom space to promote air circulation and reduce humidity. However, in some transformer substation bottom structures with moisture-proof and condensation-proof features, moisture in some corners cannot be expelled by the blower due to obstruction by internal objects, causing moisture to seep into the equipment and damage it. Utility Model Content

A toothed plate 11 is fixedly connected inside the sliding plate 3. A rotating shaft 4 is slidably connected inside the sliding plate 3.

A ring pipe 8 is fixedly connected to the outside of both the motor 6 and the counterweight 7. An air inlet 9 is located at the outside of the ring pipe 8. A through pipe 10 is fixedly connected to the outside of the ring pipe 8 for absorbing moisture from any part of the base 1.

[0033] Reference Figure 4 , Figure 5 and Figure 6 The base 1 is internally fixedly connected to a fixing plate 12, and the top of the slide plate 3 is fixedly connected to a fixing plate 13. The fixing plate 12 is externally fixedly connected to a motor 14. The drive end of the motor 14 is fixedly connected to a rotating shaft 17, which passes through the fixing plate 12 to allow the rotating shaft 17 to rotate. The rotating shaft 17 is externally sleeved with a sleeve 15. One end of the sleeve 15 is fixedly connected to one end of a pipe 10, and the other end of the sleeve 15 is fixedly connected to a T-shaped pipe 18 for conveying moisture. One end of the T-shaped pipe 18 is fixedly connected to an air pump 16, which is fixedly connected to the top of the slide plate 3. The output end of the air pump 16 is fixedly connected to an air outlet pipe 19, which passes through the base 1 to discharge moisture.

[0034] Reference Figure 3 , Figure 6 Angle steel 20 is fixedly connected to the outside of the channel steel 2. Insulating rock wool board 21 is fixedly connected to the inside of the base 1. Ventilation hole 23 is opened on the outside of the base 1 to provide support. Rain shield 24 is fixedly connected to the outside of the base 1. Fixing block 3 22 is fixedly connected to the outside of the channel steel 2. Top plate 32 is fixedly connected to the inside of the base 1. Net cage 25 is slidably connected to the outside of fixing block 3 22 to prevent rainwater from entering the base 1 through ventilation hole 23.

[0035] Reference Figure 6The base 1 has a slot on its outside, and a blocking block 26 is slidably connected inside the slot. The blocking block 26 is located at one end of the wire mesh cage 25. A receiving block 27 is fixedly connected to the outside of the blocking block 26. A rotating rod 28 is rotatably connected inside the receiving block 27 for fixing the wire mesh cage 25. A connecting rod 29 is fixedly connected to the outside of the rotating rod 28. A rotating rod 30 is fixedly connected to the outside of the connecting rod 29. A receiving block 31 is rotatably connected to the outside of the rotating rod 30. The receiving block 31 is fixedly connected to the outside of the base 1 for moving the blocking block 26.

[0036] Working principle: When there is moisture inside the base 1, the air pump 16 is started, and the moisture inside the base 1 is drawn in through the air inlet 9 of the ring pipe 8. Then, it is transported through the through pipe 10, the sleeve 15 and the T-shaped pipe 18, and discharged through the air outlet 19. At the same time, the motor 6 is started to drive the rotating shaft 4 to rotate, which in turn drives the gear 5 to rotate. The gear 5 is engaged with the toothed plate 11, allowing the gear 5 to move along the sliding plate 3. This drives the motor 6 and the counterweight 7 to move along the limiting plate, which in turn drives the ring pipe 8 to move. This allows the ring pipe 8 to draw in moisture from any part of the space inside the base 1 and discharge it through the air outlet 19, ensuring that the moisture in the base 1 is discharged and will not affect the equipment.

[0037] Simultaneously, motor 14 is started, driving the rotating shaft 17 to rotate, allowing the sleeve 15 wound around the outside of the rotating shaft 17 to be stored and released, ensuring that the through pipe 10 connected to one end of the sleeve 15 can always remain straight, allowing the through pipe 10 to follow the movement of the ring pipe 8 for storage and release, ensuring that the through pipe 10 does not affect the movement of the ring pipe 8.

[0038] The channel steel 2 in the base 1 provides support, ensuring sufficient mechanical strength and corrosion resistance to support the overall structure and resist external impacts. The base 1 and channel steel 2 are connected by angle steel 20. The heat-insulating rock wool board 21 serves as the heat insulation material for the transformer housing, mainly used to insulate against external high temperatures and reduce internal temperature. Its water-repellent properties prevent moisture intrusion and ensure a stable operating environment for the equipment. At the same time, the ventilation holes 23 on the housing promote air convection, dissipating the heat generated by the transformer operation and preventing overheating. The rain shield 24 is installed at the ventilation holes 23 to block rainwater penetration while allowing air circulation. The wire mesh cage 25 slides within the fixing block 3 22, aligned with the ventilation holes 23, to prevent external dust and other contaminants from entering the interior of the base 1 through the ventilation holes 23.

[0039] When there is too much dust on the wire mesh cage 25, the connecting rod 29 is rotated by the rotating rod 30. By holding the connecting rod 29 and rotating it, the rotating rod 28 drives the receiving block 27 to move, thereby moving the blocking block 26 in the slot. The blocking block 26 is pulled out, and the wire mesh cage 25 is moved out through the slot. After cleaning the wire mesh cage 25, it is put back, and the blocking block 26 is put back into the slot.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
