Description

Technical Field

[0001] This utility model relates to a fan room, and more particularly to a modular prefabricated fan room. Background Technology

[0002] Existing wind turbine rooms are mostly made of concrete, which has a long construction period and high cost.

[0003] To reduce costs, prefabricated wall panels have emerged, such as the prefabricated fan room wall panel disclosed in Chinese Patent CN209603336U.

Detailed Implementation

[0016] The present invention will now be further described with reference to the accompanying drawings.

[0017] like Figures 1 to 4 As shown, a modular prefabricated fan room includes a concrete foundation 4, a modular frame, a fireproof board 3, a fixing bracket 6, a power distribution cabinet 11, a detection door, and rainproof louvers 10. The concrete foundation 4 is cast on the building roof 5 and is rectangular, with three sets arranged in parallel. The modular frame is installed on the concrete foundation 4, with the two ends of the bottom of the modular frame pressing against the two outer concrete foundations 4 respectively, and the middle concrete foundation 4 located in the middle of the bottom of the modular frame. The fireproof board 3 is fixed to the modular frame and has air inlet holes and fixing holes 9. The fixing holes 9 are used to install air ducts, and the air inlet holes are used for air intake. The fireproof board 3 and the modular frame together form the fan room 7. The fixed bracket 6 is fixed to the top of the concrete foundation 4 by expansion bolts and is connected to the three concrete foundations 4 respectively. The fixed bracket 6 is located in the fan 7 room and is used to fix the fan 7. The fan 7 is set opposite to the fixing hole 9. The power distribution cabinet 11 is installed on the fireproof board 3 and is located in the fan 7 room. The maintenance door 8 is installed on the fireproof board 3 by hinges. The rainproof louver 10 is fixed on the air inlet for ventilation and to prevent rainwater from entering the fan 7 room.

[0018] The use of a frame structure and readily available fireproof panels makes assembly convenient and quick, which can be completed within a few days, greatly shortening the construction cycle, reducing costs, and providing excellent fire resistance.

[0019] The modular frame includes columns 1 and connectors 2. Columns 1 are prefabricated and cut according to actual conditions. Connectors 2 are used to connect adjacent columns 1, allowing the columns 1 to form a rectangular frame, thus obtaining the modular frame. Columns 1 use 1.2mm thick reinforcing material, and their surface is sprayed with fluorocarbon powder and then baked to obtain an anti-corrosion layer. Connectors 2 use aluminum alloy corner heads. To ensure connection strength, the average thickness of the aluminum alloy corner heads is not less than 3.9mm. The columns adopt a rhomboid structure and are equipped with rhomboid corner protectors. The rhomboid corner protectors are made of aluminum alloy, using a one-piece casting process, which prevents rusting and weld failure, and provides a good appearance.

[0020] To prevent flooding, the height of concrete foundation 4 is greater than 200mm.

[0021] Fireproof board 3 comprises, from the inside out, an inner lining board, a modified silicocalcium perlite board, and an outer lining board. The inner lining board consists of a 0.2mm thick color steel plate. The outer lining board consists of a 0.5mm thick fingerprint-resistant coated anti-corrosion board. After molding, the fireproof board is edged and sealed with anti-corrosion metal profiles. The total thickness of the fireproof board after edge sealing is 22.5mm. To ensure the strength of the fan room itself, the density of the fireproof board is not less than 550kg / m3, and the material is modified silicocalcium perlite board. Fireproof board 3 has good strength and fire resistance. The cutting dimensions of the fireproof board have errors, and there will be gaps when combined with the column material. The edge sealing of the fireproof board can adjust these gaps.

[0022] The inspection door 8 is made of fireproof board 3.

[0023] To improve sealing and prevent rainwater from entering the duct, a rain cover 12 is included. The rain cover 12 is located outside the fan room 7 and above the fixing hole 9. A sealing layer, including sealant, is provided between the rain cover 12 and the fireproof board 3. The outer surface of the rain cover 12 is coated with an outdoor-type fluorocarbon powder coating. The thickness of the rain cover 12 is 1mm. The joint between the rain cover 12 and the fireproof board 3 of the fan room is treated with sealant to prevent rainwater from flowing back through the joint.

[0024] To reduce safety hazards during typhoons, the expansion bolts are fixed to the concrete foundation 4 using #10 expansion bolts, with a fixing spacing of 1500mm.

[0025] The top of the 7th fan chamber has a slope to facilitate rapid drainage.

[0026] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
