The utility model discloses can effectively solve ordinary shutter and leak rain, leak sand by wind, ventilation performance low scheduling problem.

Description

Wind generating set air outlet rain-proof sand prevention ventilation shutter

Technical Field

The utility model belongs to the technical field of wind generating set's technique and specifically relates to indicate a rain-proof sand prevention ventilation shutter of wind generating set air outlet.

Background

At present, a shutter is mostly adopted by a megawatt wind generating set as an air outlet structure, however, the wind generating set is in a severe working environment, the ventilation performance requirement is high, the shutter has certain vibration, the problems of rain leakage, sand leakage, low ventilation performance and the like often occur in a common shutter, and the requirements of ventilation, rain prevention and sand prevention of the wind generating set cannot be met. In order to effectively solve the problems, the rain-proof and sand-proof ventilation shutter of the wind generating set is designed, so that the ventilation performance requirement can be met, and the rain-proof and sand-proof effects can be achieved effectively.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a safe and reliable's rain-proof sand prevention ventilation shutter of wind generating set air outlet, can effectively solve ordinary shutter and leak rain, leak sand, ventilation performance low grade problem.

In order to achieve the above object, the present invention provides a technical solution: the utility model provides a rain-proof sand prevention ventilation shutter of wind generating set air outlet, includes frame, fixed tripe and activity from the tripe that hangs down, fixed tripe is located frame air outlet department outwards for rainwater and wind sand that the outside was blown stops, the activity is located frame air inlet department inwards from the tripe that hangs down, and this activity is in from the confined state that hangs down when static from the tripe that hangs down, can carry out the secondary to rainwater and wind sand that get into in the frame and block, prevents that they from getting into wind generating set's cabin, the activity is from the tripe that hangs down adopting the check valve design for the air current can only be blown from the cabin inside outwards, the inside of frame is equipped with a plurality of through-holes for rainwater and wind sand in the discharge entering frame.

Further, the fixed louver is composed of a plurality of V-shaped louver blades with the same orientation.

Compared with the prior art, the utility model, have following advantage and beneficial effect:

1. the rain-proof performance of the shutter is improved.

2. The wind and sand prevention performance of the shutter is improved.

3. Has good ventilation performance.

4. The whole structure is simple, and the maintenance is convenient.

Detailed Description

The present invention will be further described with reference to the following specific embodiments.

As shown in fig. 1 to fig. 3, the wind turbine generator system air outlet rainproof, sand-proof and ventilating shutter provided in this embodiment includes a frame 1, a fixed shutter 2 and a movable self-hanging shutter 3, the fixed shutter 2 is disposed at an outward air outlet of the frame 1, the fixed shutter 2 is composed of a plurality of V-shaped shutter blades 21 facing in the same direction, used for blocking rainwater and wind sand blown from the outside, the movable self-hanging shutter 3 is arranged at the air inlet of the frame 1 facing inwards, and the movable self-hanging shutter 3 is in a self-hanging closed state when being static, can secondarily block rainwater and wind sand blown into the frame 1 and prevent the rainwater and the wind sand from entering a cabin of the wind generating set, adopts a one-way valve design for the movable self-hanging shutter 3, so that the airflow can only be blown out from the interior of the nacelle, and the interior of the frame 1 is provided with a plurality of through holes (not shown) for discharging the blown-in rain and wind sand.

The working principle of the rain-proof sand-proof ventilating shutter of the embodiment is as follows:

when ventilation is carried out, the air flow in the engine room blows away the movable self-hanging shutter 3, then passes through the fixed shutter 2, and finally is discharged to the outside of the wind generating set.

When the wind is not used, under the condition that rain or sand wind exists outside the wind generating set, rain or sand wind blows on the louver, most of rain or sand wind can be blocked by the fixed louver 2, even if a small amount of rain or sand wind can pass through the fixed louver 2, the rain or sand wind can be blocked by the movable self-hanging louver 3 at the back, and finally the rain or sand wind is discharged from the through hole for discharging the rain and the sand wind.

The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that all the changes made according to the shape and principle of the present invention should be covered within the protection scope of the present invention.

Claims (2)

1. The utility model provides a wind generating set air outlet rain-proof sand prevention ventilation shutter which characterized in that: including frame, fixed tripe and activity from the tripe that hangs down, fixed tripe is located frame air outlet department outwards for rainwater and wind sand that the outside was blown out blocks, the activity is located frame air inlet department inwards from the tripe that hangs down, and this activity is in from the closed condition that hangs down when static from the tripe that hangs down, can carry out the secondary to rainwater and wind sand that get into in the frame and block, prevents that they from getting into wind generating set's cabin, the activity is from the tripe design that hangs down that adopts the check valve for the air current can only be blown from the cabin inside outwards, the inside of frame is equipped with a plurality of through-holes for rainwater and wind sand in the discharge entering frame.
