Description

Technical Field

[0001] The present application relates to the technical field of dampers, and in particular to a self-supporting steel chimney damper. Background Art

[0002] A free-standing steel chimney damper is a device installed on a free-standing steel chimney. Its main function is to reduce the vibration response of the chimney under external dynamic loads such as wind loads and earthquakes. For example, in strong winds, the chimney will shake due to the force of the lateral wind. The damper can convert this vibration energy into other forms of energy such as heat through its own energy dissipation mechanism, thereby suppressing excessive vibration of the chimney and avoiding structural fatigue damage caused by long-term and large-scale vibration of the chimney.

[0003] Regarding the above-mentioned related technologies, the inventor believes that firstly, the installation structure of the damper in the existing self-supporting steel chimney damper structure is complex, requiring a large amount of on-site processing and precise installation on the chimney, and the replacement of some damper components is complicated, resulting in high maintenance costs. Utility Model Content

[0004] The purpose of this application is to provide a self-supporting steel chimney damper to improve the problems of complex installation and high maintenance cost of the existing damper structure.

[0005] The present application provides a self-supporting steel chimney damper adopting the following technical solution:

The through-hole comprises a first threaded hole, and a second threaded hole, wherein the bosses comprise a first threaded hole, and a second threaded hole. The bosses comprise a second threaded hole, and a second threaded hole. The bosses comprise a second threaded hole, and a second threaded hole.

[0007] By adopting the above technical solution, a flexible connection between the damper body and the mounting base is achieved. The mounting groove provides an installation position for the first connecting hinge, so that it can be hinged to the damper body, thereby allowing the damper body to move within a certain range. The cooperation between the connecting plate and the positioning groove and the connection between the first threaded hole and the second threaded hole by the connecting screw ensure the stability and reliability of the connection, so that the damper body can be firmly installed on the mounting base while being able to adapt to certain deformation and vibration during operation. The second connecting hinge enables the damper body to be connected to the mounting plate, so that the damper can be conveniently installed in a suitable position of the self-supporting steel chimney, facilitating the installation, disassembly and maintenance of the damper structure.

[0008] Optionally, the protective coating assembly includes an epoxy zinc-rich primer, which is fixedly sleeved on the outer surface of the damper body, the outer surface of the epoxy zinc-rich primer is fixedly sleeved with a polyurethane topcoat, and the outer surface of the polyurethane topcoat is fixedly sleeved with an inorganic zinc-rich coating, and the outer surface of the inorganic zinc-rich coating is fixedly sleeved with a fluorocarbon coating.

[0009] By adopting the above technical scheme, the epoxy zinc-rich primer has good adhesion and cathodic protection, which can prevent corrosion of the metal substrate and provide basic anti-corrosion protection for the coating system. The polyurethane topcoat has excellent weather resistance and chemical corrosion resistance, and can protect the underlying coating from erosion by ultraviolet rays, rain, acid rain, etc. The inorganic zinc-rich coating further enhances the anti-corrosion performance, especially in special environments such as high temperature. It has good stability. The fluorocarbon coating has excellent weather resistance, corrosion resistance and low surface energy, and can withstand the erosion of extremely harsh climatic conditions and chemical pollutants, enabling it to operate stably for a long time in the complex working environment of the free-standing steel chimney, effectively protecting the steel chimney structure from corrosion and damage.

[0010] Optionally, the internal structures of the multiple connection components are configured identically.

[0011] By adopting the above technical solution, multiple connecting components with the same structure make the installation method and stress conditions of each damper body similar, thereby improving the reliability of the overall structure.

[0012] Optionally, the plurality of damper bodies are distributed in a ring array.

[0013] By adopting the above technical solution, the annular array distribution makes the arrangement of the dampers on the mounting base more uniform, which can more effectively withstand forces and vibrations from different directions, thereby better protecting the self-supporting steel chimney.

[0014] Optionally, the inner wall of the mounting plate is arranged in an arc shape, and the inner wall of the mounting plate is made of a non-slip material.

[0015] By adopting the above technical solution, the arc-shaped design of the inner wall of the mounting plate and the anti-slip material increase the fit and friction with the external structure, thereby improving the stability of the connection.

[0016] Optionally, two through-type mounting holes are provided at one end of the mounting plate, and the inner walls of the two mounting holes are threaded.

[0017] By adopting the above technical solution, the threaded design of the mounting hole facilitates fixed installation using connecting parts such as bolts.

[0018] Optionally, the shape of the outer surface of the connecting plate is the same as the shape of the inner wall of the positioning groove, and the outer surface of the connecting plate is movably engaged with the inner wall of the positioning groove.

[0019] By adopting the above technical solution, the accuracy and stability of the connection are further improved, so that the connecting plate can be accurately installed in the positioning groove, avoiding shaking or displacement during installation and use, and ensuring the tightness and reliability of the connection.

[0020] Optionally, the fluorocarbon coating, inorganic zinc-rich coating, polyurethane topcoat and epoxy zinc-rich primer are arranged in a sequentially nested manner.

[0021] By adopting the above technical solution and the sequentially sleeved combined design, the durability of the damper body is greatly improved and its service life is extended.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The utility model designs the damper connection structure into multiple modules by setting a connection mechanism, which makes it easy to disassemble the damper body and replace parts, improves installation efficiency, and reduces the maintenance cost of the damper structure.
