Description

Technical Field:

[0001] The utility model belongs to the technical field of closed cooling towers, and particularly relates to a cooling tower bottom frame structure with vibration damping performance. Background Art:

[0002] Closed cooling towers are usually installed on the roof. When the closed cooling tower is operating, the equipment will generate vibrations, and these vibrations will be transmitted to the floor through the channel steel frame at the bottom of the closed cooling tower, causing damage to the floor. To solve this problem, several vibration damping support feet are usually drilled and installed at the bottom of the channel steel frame to reduce the damage to the floor caused by vibrations.

[0003] During actual use, since the entire weight of the closed cooling tower is borne by several vibration damping support feet, the floor is unevenly stressed, which is more likely to cause damage to the floor.

[0019] Such as Figures 1-3As shown in the figure, a cooling tower bottom frame structure with vibration damping performance includes an upper support 1, a lower support 2, a main vibration damping member 3, and a secondary vibration damping member 4. The main vibration damping member 3 and the secondary vibration damping member 4 are made of neoprene. Neoprene has a relatively high damping coefficient, obvious vibration damping effect, and good durability, and is suitable for outdoor harsh climates. The main vibration damping member 3 is a grid-shaped structure, the secondary vibration damping member 4 is a square structure with a hole in the middle, and the width of the main vibration damping member 3 is greater than the width of the secondary vibration damping member 4. The secondary vibration damping member 4 includes secondary vibration damping units 40. Two secondary vibration damping units 40 are arranged axially symmetrically to form a secondary vibration damping member 4, and the secondary vibration damping unit 40 is a square structure with a hole in the middle.

[0020] Grooves are respectively arranged on the bottom surface of the upper support 1 and the top surface of the lower support 2. The grooves include a main groove 5 and secondary grooves 6. The main groove 5 is located in the middle of the bottom surface of the upper support 1 and the top surface of the lower support 2, and the secondary grooves 6 are symmetrically arranged on both sides of the main groove 5. Main splicing blocks 30 are arranged on the upper and lower end faces of the main vibration damping member 3, and the structure of the main splicing blocks 30 is matched with that of the main groove 5. Secondary splicing blocks 41 are arranged on the upper and lower end faces of the secondary vibration damping member 4, and the structure of the secondary splicing blocks 41 is matched with that of the secondary groove 6. By splicing the main splicing blocks 30 with the main groove 5, the main vibration damping member 3 is connected to the upper support 1 and the lower support 2. By splicing the secondary splicing blocks 41 with the secondary groove 6, the secondary vibration damping member 4 is connected to the upper support 1 and the lower support 2. The main vibration damping member 3 and the secondary vibration damping member 4 form a vibration damping layer, and the upper support 1, the vibration damping layer, and the lower support 2 form a uniform load-bearing structure.

By combining the bottom frame and the vibration damping structure into one, the bottom frame has its own vibration damping function, which not only improves the vibration damping effect, but also evenly distributes the weight of the cooling tower on the bottom frame, reducing the uniform load on the floor and the damage to the floor. The main vibration damping member mainly bears the vertical load and plays a main vibration damping role. The secondary vibration damping member mainly bears the lateral load to cope with the vibration caused by the crosswind on the high-rise roof.
