Abstract
The utility model provides a system for preventing sand storm. The system comprises an engine room cover, a first ventilating device and a dust filter, wherein the first ventilating device and the dust filter are arranged on the engine room cover. The first ventilating device is a uni-directional operation device. Along the flow direction of outside air entering an engine room through the first ventilating device, the filter is arranged at the upper stream of the first ventilating device. The system for preventing sand storm can effectively prevent sand storm from entering the interior of the engine room of a wind turbine, thus greatly improving the reliability of the wind turbine and prolonging the service life of parts.
Description
Technical field
The utility model relates to a kind of sand prevention dust storm system, relates in particular to a kind of sand prevention dust storm system that is used for the wind-powered electricity generation unit.
Background technique
Because the desert temperature difference round the clock is very big, can make air that wind takes place to flow and produce, therefore, many wind-driven generators factory, especially some large-scale wind-driven generator factories all are built in the desert.But because dust storm is big in the desert, parts such as the pylon in wind-powered electricity generation unit, especially the wind-powered electricity generation unit, cabin, blade should satisfy the requirement of sand prevention dust storm, in case the grains of sand add the wearing and tearing of speed wind-power unit.The sand prevention dust storm also is the principal element of considering in the group selection of wind-powered electricity generation machine usually.Yet the most wind power generating set that are installed on northern sandstorm area at present are not provided with sand prevention dust storm system, thereby have seriously influenced the working life of wind-powered electricity generation unit.For example in the Takla Makan Desert of Xinjiang, when wind speed 30m/s, airborne sand dust reaches 212mg/m
3, be 140 times of general environment prescribed limit values.Therefore, how preventing the destruction of sandstorm to the wind-powered electricity generation unit, is to be based upon the problem that the wind power plant in the desert needs emphasis to consider.
The utility model promptly proposes a kind of sand prevention dust storm system that is used for the wind-powered electricity generation unit at above-mentioned defective, can effectively improve the desertification dirt performance of wind-powered electricity generation unit.
The model utility content
Goal of the invention of the present utility model is to provide a kind of can prevent effectively that sandstorm from entering the sand prevention dust storm system of wind-powered electricity generation set engine room inside, thereby improves greatly the reliability of unit and the working life of component.
For achieving the above object, the utility model provides a kind of like this sand prevention dust storm system, and it comprises engine room cover, first ventilation plant and sand and dust filtrating equipment, and described first ventilation plant and sand and dust filtrating equipment are arranged on the described engine room cover.
According to further improvement of the utility model, described first ventilation plant is the device of unidirectional running.
According to further improvement of the utility model, along the flow direction that outside air enters the cabin by described first ventilation plant, described filtrating equipment is arranged on the upstream of described first ventilation plant.
According to further improvement of the utility model, described sand prevention dust storm system comprises at least one first ventilation plant.
According to further improvement of the utility model, described first ventilation plant comprises axial-flow blower or centrifugal blower.
According to further improvement of the utility model, described sand prevention dust storm system also comprises the air-out passage.
According to further improvement of the utility model, described air-out passage is little open channel.
According to further improvement of the utility model, described air-out passage is fit up gap or other opening on the described engine room cover.
According to further improvement of the utility model, described sand prevention dust storm system also comprises at least one second ventilation plant.。
According to further improvement of the utility model, described sand prevention dust storm system also comprises a ventilated port that is used for described second ventilation plant.
For above-mentioned and other purposes, feature and advantage of the present utility model can be become apparent, a preferred embodiment cited below particularly, and cooperate appended accompanying drawing to be elaborated.
Description of drawings
Fig. 1 is the erection drawing of sand prevention dust storm of the present utility model system.
Embodiment
As shown in Figure 1, sand prevention dust storm of the present utility model system comprises engine room cover 1, first ventilation plant 2 and sand and dust filtrating equipment (not shown), and described first ventilation plant 2 and sand and dust filtrating equipment are arranged on the described engine room cover 1.Described first ventilation plant 2 can be axial-flow blower or centrifugal blower.
Principle according to the sudden and violent system of sand prevention car of the present utility model is: when sandstorm comes temporarily, manage to make to form malleation, promptly the cabin internal air pressure is higher than external pressure in the cabin in, takes the sand and dust air and enters the cabin thereby play the prevention outside.
For this reason, the sudden and violent system of sand prevention car of the present utility model comprises first ventilation plant 2 of at least one unidirectional running, and along outside air by the flow direction that described first ventilation plant 2 enters the cabin, described filtrating equipment is arranged on the upstream of described first ventilation plant 2.
When sandstorm comes to start described first ventilation plant 2 temporarily, outside air is sucked in the cabin.Because the provided upstream at first ventilation plant 2 is equipped with filtrating equipment, so the sand and dust in the outside air are filtered before entering first ventilation plant.This sand prevention dust storm system also comprises air-out passage 4, the for example fit up gap of the fit up gap of engine room cover and pylon, engine room cover and cowling and other openings, but these opening areas are all very little, and the air quantity of described first ventilation plant 2 is very big, therefore can keep malleation, outside to take the sand and dust air in the cabin always can not enter engine room inside.
In addition, described sand prevention dust storm system also comprises second an independent ventilation plant (not shown), is used for giving in the cabin period in non-sandstorm taking a breath.Described second ventilation plant can be an axial-flow blower.Described sand prevention dust storm system also comprises a ventilated port 3 that is used for described second ventilation plant.
It should be noted that the above only for preferred embodiment of the present utility model, the foregoing description only is to be used for explanation but not in order to limit scope of the present utility model, category of the present utility model is defined by claims.All equivalent variations or replacements of doing according to the utility model all should belong to covering scope of the present utility model.
