Abstract
The invention discloses an unpowered fan with multi-operation modes. According to the unpowered fan provided by the invention, a ventilation switching mechanism is arranged at the ventilation opening of the unpowered fan, the ventilation switching state is provided with at least two working states: when the ventilation switching mechanism is under an opened state, the ventilation opening is opened and the unpowered fan conducts ventilating and heat dissipating; and when the ventilation switching mechanism is in under a closed state, the ventilation opening is closed and the unpowered fan conducts heat preservation. As the ventilation switching mechanism is arranged at the ventilation opening of the unpowered fan, and the ventilation state of the unpowered fan is controlled by the ventilation switching mechanism, so that the unpowered fan is provided with a ventilating and heat dissipating function and as well as a heat preservation function, the working requirement of multi-operation modes of the unpowered fan is satisfied, and the application range of the unpowered fan is expanded.
Description
Technical field
The present invention relates to unpowered blower fan technical field, relate in particular to the unpowered blower fan of a kind of multi-operating mode, unpowered blower fan has ventilation heat sinking function and heat insulation function.
Background technique
In buildings such as industrial premises, often adopt unpowered blower fan to carry out exhaust ventilation.Unpowered blower fan does not need the people for power is provided, and its power is mainly derived from the hot air flow of indoor rising and outdoor natural wind, by promoting the turbine main frame rotation of blower fan, to reach the effect of ventilation.Compare with driven fan, unpowered blower fan has that cost is low, noise free, no energy consumption, advantages of environment protection, and its application is very extensive.
The ventilation state of traditional unpowered blower fan is generally open type, and after unpowered blower fan installed, blower fan was in 24 hours operating conditions, so blower fan can carry out air draft incessantly.Then inapplicable for the manufacturing shop that ventilation heat radiation in summer, winter need be incubated.Current, generally adopt plastic pellicle that the turbine main frame of unpowered blower fan is wrapped up fully, force the blower fan stall, stop exhaust, to reach the purpose of insulation.
Though the insulation processing mode of above-mentioned unpowered blower fan is effectively simple, also has many potential safety hazards:
1, workman's personal safety hidden danger: the workman generally will arrive the roof by vertical metope and construct, and the workman is in the climbing process, and personal safety can not get ensureing;
2, plastic pellicle easily breaks, and causes roof leaking: the workman easily causes film breaks in the process of parcel; Film wrapped well after, high wind can blow film in the sharp blade edge friction of blower fan, causes film to be cut;
3, construction can damage the water-proofing material of blower fan periphery: the workman inevitably need trample around blower fan in the process of construction, is easy to like this cause coming off and breaking of water-proofing material, thereby causes roof leaking.
Therefore, how to improve on the basis of existing unpowered blower fan, when realizing the ventilation heat sinking function, also have heat insulation function, become the technical problem that those skilled in the art are badly in need of solving.
Summary of the invention
Problem at the prior art existence, the objective of the invention is to propose the unpowered blower fan of a kind of multi-operating mode, unpowered blower fan has ventilation heat sinking function and heat insulation function, has satisfied the multi-operating mode job requirements of unpowered blower fan, has expanded the application area of unpowered blower fan.
For reaching this purpose, the present invention by the following technical solutions:
The unpowered blower fan of a kind of multi-operating mode is provided with the ventilation switching mechanism at the ventilated port of unpowered blower fan, and described ventilation switching state has two working staties at least:
Be under the open mode at the ventilation switching mechanism, ventilated port is opened, the heat radiation of taking a breath of unpowered blower fan;
Be under the closed condition at the ventilation switching mechanism, ventilated port is closed, and unpowered blower fan is incubated.
Preferably, described ventilation switching mechanism comprises venetian blind and motor, and motor is connected with venetian blind and is used for the opening and closing of control venetian blind.
Preferably, described unpowered blower fan comprises turbine main frame, centre circle, middle seat and base, and the bottom opening of base is the ventilated port of described unpowered blower fan.
Based on disclosing of above technological scheme, the present invention possesses following beneficial effect:
Among the present invention, be provided with the ventilation switching mechanism at the ventilated port of unpowered blower fan, the ventilation switching mechanism comprises venetian blind and motor, and the opening and closing by the Electric Machine Control venetian blind are to realize the multi-operating mode operation of unpowered blower fan; When motor was opened venetian blind, ventilated port was opened, the heat radiation of taking a breath of unpowered blower fan, and when motor cut out venetian blind, ventilated port was closed, and unpowered blower fan is incubated.By controlling the ventilation state of unpowered blower fan, unpowered blower fan has ventilation heat sinking function and heat insulation function, has satisfied the multi-operating mode job requirements of unpowered blower fan, has expanded the application area of unpowered blower fan.
Description of drawings
