Description

Technical Field

[0001] The present application relates to the field of roof waterproof structures, and in particular to a roof fan rain cover construction structure. Background Art

[0002] Roof fans, also called roof fans or ventilators, are devices installed on the roof of a building for ventilation and exhaust. Their main function is to promote indoor air flow, remove heat, moisture, harmful gases, and improve the comfort and safety of the indoor environment. They are widely used in industrial plants, warehouses, commercial buildings, hospitals, laboratories, etc.

[0003] Usually when installing a roof fan, it is necessary to assemble a rain cover according to the size of the roof fan to protect the fan and the ventilation system. However, the rain cover in the prior art does not have a mature and standardized construction technology, and has disadvantages to varying degrees such as complex structure, cumbersome installation, and easy leakage during use.

[0004] A Chinese patent with announcement number CN211341460U discloses a waterproof structure for a roof fan opening, which includes a fan opening opened on the roof, a fan support arranged in the fan opening, a leak-proof plate arranged around the fan support and a fan arranged above the fan support. The fan support includes four supporting legs and a "mouth"-shaped supporting frame connected to the same end of the supporting legs, and the supporting legs are all connected to the roof purlins.

[0005] The drainage cover in the waterproof structure of the roof fan opening only serves to divert rainwater falling from the top. However, rainy days are usually accompanied by natural winds of a certain direction. Rainwater has a certain inclination under the guidance of the wind and is easy to enter the fan cover from the opening of the drainage cover. It penetrates into the joint of the fan body along the placement gap between the fan and the support frame, thereby increasing the risk of damage to the fan. Utility Model Content

[0006] In order to improve the waterproof effect of the rain cover on the roof fan, the present application provides a roof fan rain cover construction structure.

[0007] The application provides a roof fan rain cover construction structure adopts the following technical solution:

[0008] A roof fan rain cover construction structure includes a vertical panel and a slanted top cap, wherein the vertical panels are provided in plurality, and the plurality of vertical panels surround a space for placing a fan, the slanted top cap is jointly arranged on the top of the plurality of vertical panels, and the slanted top cap is connected to the plurality of vertical panels to form an externally wrapped rain cover, and each of the vertical panels is provided with a plurality of ventilation plates, and each of the ventilation plates is provided with a plurality of vents for heat dissipation.

[0009] By adopting the above technical solution, the construction workers fed back the fan size measured on site to the processing factory, used 2mm thick steel plates to process the inclined top cap and facade panels in advance, and opened corresponding vents on the facade panels. The processed inclined top cap and facade panels were then transported to the site, and the outsourced rain cover was spliced ​​through welding technology, and the rain cover was welded to the wind well cap on the roof to complete the assembly. Through this design, the rain cover can not only effectively prevent rain from directly wetting the fan, but also ensure the heat dissipation effect of the fan during normal operation through the design of ventilation plates and vents. The design of the inclined top cap can guide rainwater to flow away, avoid water accumulation on the top of the rain cover, and further improve the rainproof performance.

[0010] Optionally, the four peripheral edges of the slanted top cap extend out of the outer side walls of the vertical panel.

[0011] By adopting the above technical solution, the four edges of the inclined top cap are designed to extend out of the outer side walls of the vertical panel, so that the possibility of rainwater penetrating into the interior of the rain cover through the seam between the inclined top cap and the vertical panel can be reduced.

[0012] Optionally, a plurality of heat dissipation holes are provided at the bottom of the brim of the inclined top cap extending out of the outer side wall of the vertical panel and connected to the space for placing the fan.

[0013] By adopting the above technical solution, a plurality of heat dissipation holes provided at the bottom of the brim extending from the slanted top hat are connected to the inside of the rain cover, thereby further enhancing the heat dissipation effect of the rain cover on the fan.

[0014] Optionally, a lightning rod is installed on the top of the slanted cap.

[0015] By adopting the above technical solution, the function of the lightning rod is to guide the current of lightning to be safely discharged into the earth, thereby avoiding direct damage to the wind turbine caused by lightning and improving the safety of the entire rain cover structure.

[0016] Optionally, an inspection door is provided on one or more sides of the vertical panels, and a plurality of ventilation plates are also provided on the inspection door, and a plurality of vents are provided at each ventilation plate. When the fan is in normal operation, the inspection door is in a normally closed state.

[0017] By adopting the above technical solution and setting the inspection door, when the fan needs to be inspected, it is only necessary to open the inspection door without removing the entire rain cover, which greatly improves the convenience of fan inspection. In addition, when the fan is working normally, the inspection door remains in a normally closed state to ensure the rain cover's rainproof effect on the fan. The multiple ventilation plates and vents set on the inspection door can further improve the heat dissipation performance of the rain cover.

[0018] Optionally, the inspection door and the facade panel are provided with a plurality of guide arc plates inclined upward on the inner side walls of the fan space, the arc center of each guide arc plate is located above itself, and a single guide arc plate is provided in one-to-one correspondence with a single vent hole.

[0019] By adopting the above technical solution, when rainwater is tilted with the direction of natural wind, it is easy to enter into the space where the fan is placed through the air vent, threatening the fan with short circuit and failure. The setting of the guide arc plate can prevent rainwater blown into the air vent by the wind from entering the space, and drive the rainwater hitting the guide arc plate to flow out of the air vent under the guidance of the guide arc plate, thereby improving the waterproof effect of the rain cover on the fan.

[0020] Optionally, an insect-proof net can be removably provided on the outer side walls of the inspection door and the facade panel corresponding to each ventilation panel.

[0021] By adopting the above technical solution, in summer, there are many insects, and insects can easily enter the space where the fan is placed through the vents and even block the vents, thus affecting the normal operation of the fan. A layer of fine metal mesh or polymer material mesh is added at each ventilation plate, and the mesh size is small enough to prevent insects from passing through. This insect-proof net can not only effectively prevent insects from entering, but also maintain the ventilation effect of the fan.

[0022] Optionally, an insect-attracting lamp is arranged on the outer side wall of the edge of the slanted top hat, and a collecting trough is arranged below the insect-attracting lamp, and the collecting trough is used to collect the insects that are attracted and fall.

[0023] By adopting the above technical solution, an insect trap lamp is arranged on the top or side of the rain cover, and the insects are attracted to light by their phototropism to attract them away from the air inlet of the fan. At the same time, a collection trough is arranged under the insect trap lamp to collect the attracted and fallen insects, so as to facilitate regular cleaning.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The construction workers fed back the fan size measured on site to the processing factory, and used 2mm thick steel plates to pre-process the inclined top cap and facade panels, and opened corresponding vents on the facade panels. The processed inclined top cap and facade panels were then transported to the site, and the outsourced rain cover was spliced ​​through welding technology, and the rain cover was welded to the wind well cap on the roof to complete the assembly. Through this design, the rain cover can not only effectively prevent rain from directly wetting the fan, but also ensure the heat dissipation effect of the fan during normal operation through the design of ventilation plates and vents. The design of the inclined top cap can guide rainwater to flow away, avoid water accumulation on the top of the rain cover, and further improve the rainproof performance;

[0026] 2. The edges of the four sides of the inclined top cap are designed to extend out of the outer side wall of the facade panel, so that the possibility of rainwater penetrating into the rain cover through the joint between the inclined top cap and the facade panel can be reduced;
