Description

Technical Field

[0001] The invention relates to the technical field of duct structures, and in particular to a streamlined vortex-eliminating and noise-eliminating duct structure. Background Art

[0002] The streamlined vortex-eliminating and noise-eliminating duct structure is a design structure that combines the principles of fluid mechanics and acoustics. It can eliminate vortices in fluid flow and reduce the generation of noise. The streamlined vortex-eliminating structure can be set at the water inlet of the bell tube. Its cross-sectional contour line is an arc line, and the inner and outer contour lines have the same center, and it is circular when viewed from above. This structure can effectively improve the flow state in the water inlet channel, reduce the range and intensity of the recirculation zone, and eliminate the vortex attached to the wall of the blind end top plate, thereby playing a rectifying role. The streamlined vortex-eliminating structure can optimize the fluid flow path and use sound-absorbing materials or silencers to effectively reduce the vortices and noise generated during the fluid flow process.

[0003] However, the existing vortex elimination and silencer duct structure cannot flexibly adjust the position of the vortex elimination and silencer according to the position where the vortex is generated by the fluid in the duct during use. In actual use, as the water level varies, the flow rate and direction of the water flowing into the pipe vary, the size and position of the generated vortex also deviate. The conventional fixed structure cannot be adjusted according to the rotation speed of the vortex, thereby reducing the vortex elimination effect. In addition, collision will occur between the fluid and the rectifying plate during vortex elimination, thereby generating louder noise. In view of this, the present utility model is specially proposed. Summary of the invention

[0004] The purpose of the utility model is to provide a streamlined vortex-eliminating and silencer duct structure in order to solve the above-mentioned problems. The structure has the advantages of good vortex-eliminating effect and low noise generation. The rotating seat and the rotating ring can be driven to move by adjusting the assembly, so that the position of the fluid vortex can be flexibly adjusted according to the position where the fluid vortex is generated. At the same time, the rotating ring can rotate in the opposite direction according to the rotation speed of the vortex, so as to improve the vortex-eliminating effect. The silencer plate can absorb the sound generated by the collision of the fluid, so as to reduce the noise generation.
