Abstract
The utility model discloses an anti-vibration structure of a cooling tower of a hydrodynamic fan. The anti-vibration structure comprises fins which are additionally mounted on a water inlet pipeline of a hydraulic turbine of the cooling tower of the hydrodynamic fan. The structure is reasonable in design, can effectively avoid a vortex effect, achieves an obvious anti-vibration effect for the water inlet pipeline under specific working conditions and simultaneously avoids the vibration, caused by resonance, of a cooling tower body, is high in engineering practicality and is suitable for large-area popularization.
Description
Technical field
The utility model relates to a kind of hydraulic fan cooling tower vibration-proof structure.
Background technology
The inlet channel that the hydraulic fan cooling tower vibration-proof structure that the utility model relates to is applicable to hydraulic fan cooling tower causes vibration because of vortex street effect, and then has influence on the stable environment of housing structure and occasion.Existing hydraulic fan cooling tower water inlet pipe is not done any processing, because wind speed in air duct is very fast and be vertical relation with wind direction and pipeline, so be easy to cause because of vortex street effect the resonance of inlet channel, along with this pipeline amplitude strengthens, even may have influence on the stable of housing structure, cause the generation of security incident.
In this type of environment, the inlet channel cross section of hydraulic fan cooling tower is cylindrical, and in air duct, wind speed is about 10m/s, wind direction is vertical with inlet channel, now be easy to alternately depart from inlet channel back side generation rule whirlpool, thereby vortex street effect occurs, cause pipe vibration.The Oscillation Amplitude of inlet channel and frequency and wind speed, medium, self intrinsic frequency, supporting construction etc. are relevant, when the vibration frequency of the inlet channel causing because of vortex street effect and the eigentone of housing structure approach, resonance effects between as easy as rolling off a log generation housing structure and inlet channel, badly influence housing structure stable, even cause the generation of security incident.
Utility model content
Goal of the invention: the purpose of this utility model is in order to overcome prior art deficiency, design a kind of rational in infrastructure, the vibration that can effectively avoid hydraulic fan cooling tower produced by vortex street effect because of inlet channel, and then at utmost guarantee the stability of hydraulic fan cooling tower housing structure.
Technical scheme: in order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of hydraulic fan cooling tower vibration-proof structure of the present utility model, it is to install fin additional on the hydroturbine water intake pipeline of hydraulic fan cooling tower.
Beneficial effect: compared with prior art, the beneficial effects of the utility model are:
A kind of hydraulic fan cooling tower vibration-proof structure of the present utility model, utilizes rationally effectively structure to avoid the vibration producing because of vortex street effect, simple in structure, successful.

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
As shown in Figure 1 and Figure 2, the utility model is applicable to the hydroturbine water intake pipeline place of hydraulic fan cooling tower.Hydroturbine water intake pipeline is among air duct, when axial flow blower rotarily drives air along from bottom to top moving perpendicular to water inlet pipe.When meeting certain condition, be easy to produce water inlet pipe vibration in water inlet pipe back side generation vortex street effect, and then cause the vibration of hydraulic fan cooling tower tower body, jeopardize housing structure stable.
As shown in Figure 3, the fin that the utility model is arranged in water inlet pipe back side installation rule, has effectively avoided the generation of vortex street effect, and then guarantees that water inlet pipe, not because vortex street effect produces high vibration, effectively guarantees the tower body safety and stability of hydraulic fan cooling tower.
The undeclared part that relates in the utility model is same as the prior art or adopt prior art to be realized.Be noted that for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
