Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] (like Figure 1 (As shown) A rainproof device for a transformer oil conservator comprises a transformer oil conservator 1.

[0018] To support the installation of the roof: a roof bracket 2 is provided on the ground 101 outside the transformer oil storage cabinet 1. Specifically, the roof bracket 2 has a ground support plate, and the ground support plate is fixed to the ground through anchor bolts. There are at least four roof brackets 2, and the four roof brackets 2 are respectively arranged at the four corners of the roof.

[0019] The top end of the roof support 2 supports and installs a double-slope roof 3. The double-slope roof 3 has the effect of preventing rainwater from accumulating on the roof, and the double-slope roof structure can also effectively provide sunshade.

[0020] The inner labyrinth wall panel 4 is suspended and installed inside the double-slope roof 3, that is, the suspension installation of the inner labyrinth wall panel 4 is supported by the roof steel beam support structure of the double-slope roof 3. Of course, the inner labyrinth wall panel 4 includes a suspension installation beam.

[0021] The outer side of the inner labyrinth wall panel 4 is adapted to be installed with the outer labyrinth wall panel 5; the inner labyrinth wall panel 4 and the outer labyrinth wall panel 5 prevent a large amount of rainwater from splashing in through the mutually adapted labyrinth shielding structure. The outer labyrinth wall panel 5 is a ground support structure.

[0022] The effect of using inner and outer maze shielding structures to prevent rainwater from splashing in is that the maze coordination structure also has a natural ventilation effect connected to the outside atmosphere, avoiding excessive stuffiness or humidity in the room, and there is no need to set up active fans for ventilation, which ensures ventilation effects while saving energy.

[0023] Since the labyrinth structure will inevitably accumulate a certain amount of rainwater when the wind and rain are too strong, a plurality of drainage holes 6 are provided at the lowest point of the bottom end of the inner labyrinth wall panel 4; the drainage holes 6 are provided at one to three points along the length direction of the inner labyrinth wall panel 4; the drainage holes 6 at each drainage point are connected to the floor drain 8 provided on the ground 101 through a vertically arranged drainage pipe 7.

[0024] Preferably, the floor drain 8 is a continuous drainage floor drain extending in the length direction of the room, that is, a drainage ditch, to ensure the dryness of the floor of the transformer oil storage cabinet 1 .

[0025] In the above embodiment, as a further improvement of the present utility model: the left and right sides of the double-sloped roof 3 are respectively provided with pull-out plates 9 for extending the rain-shielding area of ​​the roof.

[0026] The pull-out plate 9 is locked in its extended position by a top screw 10. That is, a thread hole is formed at the low point of the double-slope roof 3; the thread hole is screwed to fit the top screw 10; the top screw 10 is used to press the outer wall of the pull-out plate 9 to lock the pull-out position of the pull-out plate 9.

[0027] The pull-out plate 9 is adapted to slide or roll with the pull-out groove of the double-slope roof 3. When rolling, rollers are installed at the outer ends of the pull-out plate 9, and the pull-out position of the pull-out plate 9 is adjusted by rolling friction between the rollers and the roller grooves.

[0028] In the above embodiment, as a further improvement of the utility model, a rain curtain 11 is provided at the lowest end of the pull-out plate 9. Specifically, the rain curtain 11 can be the same as the hanging structure of a curtain, and can be hung and installed at the end of the pull-out plate 9; or the rain curtain 11 can be fastened to the end of the pull-out plate 9 by using thumbtacks.

[0029] In the above embodiment, as a further improvement of the utility model: to prevent the rain curtain 11 from being blown away by the wind, a weight bar 1101 is provided at the bottom of the rain curtain 11. The rain curtain 11 wraps the weight bar 1101 inside and then fastens it with thumbtacks to achieve the installation of the weight bar 1101 at the end of the rain curtain 11.

[0030] In the above embodiment, as the preferred technical solution of the utility model: the labyrinth working part of the inner labyrinth wall panel 4 has a U-shaped rainproof structure 401; the labyrinth working part of the outer labyrinth wall panel 5 has a right-angle Z-shaped rainproof structure 501. The U-shaped rainproof structure 401 and the Z-shaped rainproof structure 501 cooperate with each other to form a labyrinth rainproof structure with natural ventilation function.

[0031] To ensure the rainproof effect: the turning point of the Z-shaped rainproof structure 501 is located at the open end of the U-shaped rainproof structure 401 to form a preliminary shielding. The end vertical side wall 502 of the turning point of the Z-shaped rainproof structure 501 is close to and higher than the open end vertical side wall of the U-shaped rainproof structure 401, forming a second shielding and ensuring the rainproof effect.

[0032] The working principle of the utility model is as follows: a plurality of roof brackets 2 are built on the ground 101, and the installation of the double-slope roof 3 is supported by the roof brackets 2; then the labyrinth wallboard 4 is suspended and installed through the double-slope roof 3; the labyrinth structure composed of the labyrinth wallboard 4 and the outer labyrinth wallboard 5 blocks rainwater from entering the room; at the same time, the labyrinth structure composed of the labyrinth wallboard 4 and the outer labyrinth wallboard 5 ensures good ventilation performance between the room and the outside air, and avoids the air in the room being airtight and stuffy. The floor of the room discharges the accumulated water on the ground through the floor drain 8 to ensure the dryness of the ground of the transformer oil storage cabinet 1; at the same time, if a small amount of rainwater accumulates in the low-lying part of the inner labyrinth wallboard 4, the accumulated water can also be diverted into the floor drain 8 through the drainage pipe 7 from the drainage hole 6 set in the low-lying part of the inner labyrinth wallboard 4, thereby ensuring the dryness of the ground again. At the same time, by adjusting the extension length of the pull-out plate 9, the final rain and sunshade area of ​​the double-slope roof 3 can be adjusted, and the extension length of the pull-out plate 9 can be locked at any time through the top screw 10. Combined with the rain curtain 11 equipped with the pull-out plate 9, it can block a large amount of rainwater from splashing in, and has excellent rainproof and ventilation effects; it meets the electricity quality, safety, and sustainable use requirements in humid and hot areas.

[0033] From the above description, it can be found that the rainproof wall composed of the inner labyrinth wall panel 4 and the outer labyrinth wall panel 5 of the utility model can not only ensure the natural ventilation effect of the wall, but also prevent a large amount of rainwater from leaking into the wall, thereby achieving effective ventilation and rainproof effects.

[0034] Even if some rainwater accumulates at the bottom of the inner labyrinth wall panel 4, the accumulated rainwater will eventually be diverted from the drainage pipe 7 into the floor drain 8. The floor drain 8 can not only discharge the water on the ground, but also divert and discharge the accumulated rainwater in the inner labyrinth wall panel 4, thereby ensuring the dryness of the floor of the transformer oil storage cabinet 1.

[0035] The double-slope roof 3 of the utility model has a pull-out plate 9 for extending the rain-shielding area. The pull-out plate 9 can be extended and adjusted to extend in length according to the amount of rain, thereby adjusting the rain-shielding area of ​​the double-slope roof to ensure the rain-shielding effect.

[0036] The utility model has a rain-shielding curtain 11 installed at the end of the pull-out plate 9. When the rain is too heavy, the rain-shielding curtain 11 can block the rain again from the vertical surface to ensure the effect of sheltering from rain and blocking rain.

[0037] In summary, the utility model solves the technical problem of how to safely protect the transformer oil storage cabinet 1 in hot and humid rainy areas, has a ventilated, breathable, safe and reliable rain shielding effect, and has an excellent effect of preventing rainwater accumulation on the ground. It has a simple structure, is safe and reliable, and is suitable for promotion.
