Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of roof drainage, in particular to a roof drainage structure for a substation. Background Art
[0002] The substation wall mainly plays a role in defense and isolation. From the perspective of defense, the substation enclosure mainly prevents large and small animals around from entering the substation, avoiding damage to electrical equipment and causing accidents; at the same time, it also prevents non-staff who do not understand the high-voltage danger around from entering the substation and causing equipment and personal injuries; from the perspective of isolation, the substation wall can play a certain role in blocking the spread of noise inside the substation to the outside of the station boundary.
[0003] However, substations are generally built outdoors, and it is inevitable to encounter rainy days. To ensure that the inside of the substation will not be damaged due to moisture and to avoid short-circuit phenomena caused by moisture, a drainage system needs to be configured to drain rainwater.
[0004] In the prior art, most substations allow rainwater to drain naturally, that is, rainwater falls on the top of the substation and then flows along the perimeter of the substation wall. Over time, problems such as paint peeling and rusting will occur on the outer wall of the substation, which not only affects the aesthetics of the cabin but also its protection performance.
[0005] In addition, air conditioners are equipped inside the substation to avoid overheating of equipment, which leads to a large temperature difference between inside and outside and forms condensate. In the prior art, only the drain pipe of the air conditioner is used for drainage, but it cannot be completely drained. Content of the Utility Model
[0006] In view of this, the utility model provides a roof drainage structure for a substation, aiming to drain water more reasonably.
[0007] To achieve the above object, the technical solution of the utility model is as follows:
[0008] A roof drainage structure for a substation includes a substation body. A roof cover assembly is provided on the top of the substation body, and a drainage frame is arranged circumferentially around the roof cover assembly. It is characterized in that: the left, right, and lower parts of the drainage frame are all hollow structures, and the lower ends of the left, right, and lower parts all have inwardly folded folding parts. A strip-shaped water accumulation groove is formed between the folding parts and the corresponding drainage frame, and drainage holes are arranged in an array at the bottom of the strip-shaped water accumulation groove; the roof cover assembly is inclined and installed on the top of the substation body, and the left, right, and lower ends of the roof cover assembly are all supported on the folding parts and are all located above the strip-shaped water accumulation groove.
[0009] With the above structure, the inclined roof cover assembly can facilitate the guidance of rainwater, and combined with the set water collection trough, the rainwater can be guided into the water collection trough and discharged through the drainage holes at the bottom of the water collection trough, thereby allowing the rainwater to be discharged in a centralized manner.
[0010] Preferably, the upper end of the upper part of the drainage frame has an inwardly folded support boss, and the upper end of the roof cover assembly is supported on the support boss. With the above structure, the roof cover assembly can be arranged tilted, thereby facilitating the concentrated flow of rainwater in one direction.
[0011] Preferably, the roof cover assembly comprises a roof cover and a mounting frame mounted on the roof cover, and a sealing strip is provided between the roof cover and the mounting frame. With the above structure, the sealing strip can ensure that the roof cover assembly structure is more solid, and the sealing strip also makes the roof cover assembly have better dustproof, waterproof and heat insulation effects.
[0012] Preferably, a condensate channel is provided on the bottom surface of the installation frame along the length direction, a drainage groove is provided between the roof cover assembly and the drainage frame, and the drainage groove is arranged below the condensate channel. With the above structure, the condensate inside the substation can be drained.
[0013] As a preference, the drainage trough is provided with a supporting baffle adapted to the inclination angle of the roof cover assembly. The above structure can make the structure between the drainage trough and the roof cover assembly more stable.
[0014] Preferably, four drainage frames are arranged around the roof cover assembly, and any two adjacent drainage frames are connected via a connecting structure. The above structure can make the connection between the drainage frames more secure.
[0015] Preferably, the drainage frame and the drainage trough are arranged side by side and are both installed to the edge of the roof cover assembly. The above structure can ensure that rainwater does not flow along the wall of the substation.
[0016] Preferably, the roof cover plate has a three-layer structure, which includes an outer calcium silicate board layer, a metal shielding mesh layer and an inner calcium silicate board layer from the outside to the inside. The above structure can ensure the structural strength of the roof cover plate assembly.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] 1. By adopting the substation roof drainage structure provided by the present utility model, through the inclined roof cover plate assembly and the drainage frame installed on the circumferential edge of the roof cover plate assembly, it can ensure that rainwater flows along the roof cover plate assembly into the strip-shaped water accumulation trough and is discharged concentratedly from the drainage holes at the bottom of the strip-shaped water accumulation trough, thereby effectively preventing rainwater from flowing randomly along the wall of the substation and causing the wall paint to fall off and rust.
[0019] 2. Through the provided condensate water channel and the drainage trough arranged below the condensate water channel, it can also discharge the condensate water inside the substation, thereby ensuring the dryness inside the substation. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present utility model will be further described below in conjunction with the embodiments and the drawings.
[0031] The "left part", "right part", "upper part", and "lower part" mentioned in this embodiment all refer to the orientations under the top view of the substation body A.
[0032] AsFigures 1 to 3 As shown in the figure, a drainage structure for the roof of a substation includes a substation main body A. A roof cover assembly 1 is provided on the top of the substation main body A, and a drainage frame 2 is arranged circumferentially around the roof cover assembly 1. Among them, the left, right, and lower parts of the drainage frame 2 are all hollow structures, and the lower ends of the left, right, and lower parts all have folding parts 2a that are folded inward. A strip-shaped water receiving groove is formed between the folding part 2a and the corresponding drainage frame 2, and drainage holes 2b are arranged in an array at the bottom of the strip-shaped water accumulation groove. In this embodiment, the roof cover assembly 1 is inclined and installed on the top of the substation main body A. The left, right, and lower ends of the roof cover assembly 1 are all supported on the folding part 2a, and the left, right, and lower ends are all located above the strip-shaped water accumulation groove.
[0033] Through the inclined roof cover assembly 1 and the drainage frame 2 arranged circumferentially on the roof cover assembly 1, after the rainwater falls on the roof cover assembly 1, it can stably flow into the strip-shaped water accumulation groove and be discharged through the drainage holes 2b at the bottom of the strip-shaped water accumulation groove, effectively avoiding the rainwater flowing along the substation wall and causing the wall paint to fall off and rust.
[0034] As Figure 3 and Figure 4 shown in the figure, a support boss 2c that is folded inward is formed at the upper end of the upper part of the drainage frame 2, and the upper end of the roof cover assembly 1 is supported on the support boss 2c, so that the roof cover assembly 1 is inclined, thereby ensuring that the rainwater can have a downward flowing force.
[0035] As Figure 2 shown in the figure, the roof cover assembly 1 includes a roof cover 1a and a mounting frame 1b sleeved on the roof cover 1a. In this embodiment, three roof covers 1a are arranged side by side on the mounting frame 1b.
[0036] Furthermore, as Figure 10 shown in the figure, the roof cover 1a is also a layered structure, which is sequentially an outer calcium silicate board layer 1a1, a metal shielding net layer 1a2, and an inner calcium silicate board layer 1a3 from outside to inside. To ensure the structure of the roof cover 1a is more firm, in this embodiment, a strong adhesive is filled between the outer calcium silicate board layer 1a1 and the inner calcium silicate board layer 1a3. The strong adhesive can wrap the metal shielding net layer 1a2. In addition, the strong adhesive can further ensure the shielding effect and sound insulation effect of the roof cover 1a.
[0037] As Figure 8As shown, in this embodiment, a sealing strip 1c is also adhered between the roof cover plate 1a and the installation frame 1b. Through the sealing strip 1c, it can ensure that the installation between the roof cover plate 1a and the installation frame 1b is tighter, thereby preventing rainwater from penetrating through the gap between the roof cover plate 1a and the installation frame 1b and affecting the waterproof effect of the roof cover plate assembly 1. In addition, the sealing strip 1c also enables the roof cover plate assembly 1 to have better dust-proof and heat-insulating effects.
[0038] As Figure 7 and Figure 8 shown, a condensate water channel 1b1 is formed along the length direction on the bottom surface of the installation frame 1b, and a drainage groove 3 is also provided between the roof cover plate assembly 1 and the drainage frame 2. The installation position of the drainage groove 3 is just below the condensate water channel 1b1, so that the condensate water inside the substation body A can flow along the condensate water channel 1b1 to the drainage groove 3, thereby ensuring the dryness inside the substation body A.
[0039] As Figure 6 shown, the drainage frame 2 and the drainage groove 3 are arranged side by side and are both installed at the edge position of the roof cover plate assembly 1, so as to ensure that neither rainwater nor condensate water will directly flow along the substation wall, causing the wall paint to fall off and rust.
[0040] Again, as Figure 3 and Figure 5 shown, the drainage groove 3 is provided with a support baffle 3a adapted to the inclination angle of the roof cover plate assembly 1, so that the installation of the roof cover plate assembly 1 is more stable. In addition, the support baffle 3a can also play an insulating role, thereby preventing rainwater from entering the substation interior.
[0041] As Figure 1 and Figure 9 shown, in this embodiment, four drainage frames 2 are circumferentially arranged around the roof cover plate assembly 1, and any two adjacent drainage frames 2 are connected together by a connection structure 4, so as to ensure that the entire drainage frame 2 structure is more stable, and the connection structure 4 is also more convenient for installation.
[0042] Finally, it should be noted that the above description is only the preferred embodiment of the present invention. Under the inspiration of the present invention, those of ordinary skill in the art can make various similar representations without violating the purpose and claims of the present invention, and such transformations all fall within the protection scope of the present invention.
