Abstract
The invention discloses a louver control system of a wind power generation unit. The system is characterized by comprising a louver controller, a louver driving device and a louver, wherein the louver driving device is connected with the louver which is arranged at a ventilation opening of a cabin, the louver controller is connected with the louver driving device, and the louver controller is connected with an alarming signal of an automatic fire extinguishing system of a fan, and is also connected with a signal of a temperature sensor in the cabin. The system has the advantages that after a fire is determined by the automatic fire extinguishing system, the louver control system can timely control the closing of the louver at the ventilation opening of the cabin, and a sealed environment is formed in the cabin, so the fire is favorably extinguished; on the premise of no fire and normal running of the power generation unit, the louver control system can control the opening or closing of the louver at the ventilation opening of the cabin at certain temperature value according to the temperature which is obtained by the temperature sensor in the cabin, so the temperature is automatically adjusted.
Description
Technical field
The present invention relates to wind power equipment fire-fighting domain, specifically a kind of venetian blind control system of wind power generating set automatic fire extinguishing system.
Background technique
Horizontal shaft wind-power unit is a kind of very special power generation system, its inner member high concentration, particularly cabin part, and its inside is provided with the parts such as gear-box, generator, master control cabinet and brake.In order to effectively catch stable wind energy to greatest extent, the cabin of large-scale wind electricity unit and wheel hub are all arranged on the high-altitude on distance tens of meters, ground.Once breaking out of fire in wind generating set engine room, due to residing height and assembling geographical position reason, fire personnel cannot carry out fire extinguishing process to it, can only let alone burning to automatic distinguishing, cause very serious loss.Therefore, wind power generating set automatic fire extinguishing system is more and more subject to the attention in wind-powered electricity generation industry.Due to the needs of wind power generating set inner member cooling heat dissipation, nacelle cover all devises ventilated port, cabin is caused to be a kind of semi-closed state, once engine room inside breaking out of fire, after automatic fire extinguishing system spurts extinguishing medium, because engine room inside air pressure is greater than nacelle exterior, extinguishing medium will run off from ventilated port very soon, brings very large adverse effect to extinguishing effect.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above, there is provided one highly intelligentized venetian blind control system, for realizing in the cabin of semi-closed state, after automatic fire extinguishing system spurts extinguishing medium, automatically the in good time closedown to each exhaust outlet in cabin and unlatching can be implemented, in time within the time of setting, avoid the loss of extinguishing medium, to reaching the extinguishing effect of automatic fire extinguishing system the best.
Realizing technological scheme of the present invention is: a kind of venetian blind control system of wind power generating set, is characterized in that: comprise venetian blind controller, louver driving device, venetian blind; Described louver driving device is connected with the venetian blind being arranged on engine room ventilation mouth place; Described venetian blind controller connects louver driving device; Described venetian blind controller access blower fan automatic fire extinguishing system alarm signal, accesses temperature sensor signal in cabin simultaneously.
Described venetian blind controller is arranged in engine room inside.
The invention has the beneficial effects as follows:
1, ensure that extinguishing effect.After automatic fire extinguishing system confirms breaking out of fire, the venetian blind that venetian blind control system can control ventilated port place, cabin is in time closed, and makes the environment that in cabin, formation one is closed, is conducive to fire extinguishing.
2, because venetian blind is closed, automatic fire extinguishing system spurts extinguishing medium and can not run off from window.
3, complete after the putting out of engine room inside burning things which may cause a fire disaster, after continuing for some time, the venetian blind at engine room ventilation mouth place can be made to open, release cabin internal residual gas, checks so that personal security enters cabin.
4, under the prerequisite normally run without fire alarm unit, the temperature that venetian blind control system obtains according to cabin interior temperatures sensor, opens at the temperature value of setting or closes the venetian blind at engine room ventilation mouth place, realize temperature automatic adjustment.
5, simple in whole system structure, automatic operation, can adapt to the actual conditions of Wind turbines work very well.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Number in the figure: 1-venetian blind controller, 2-louver driving device, 3-venetian blind.
Embodiment
As shown in Figure 1, a kind of venetian blind control system of wind power generating set, comprises venetian blind controller 1, louver driving device 2, venetian blind 3; Described louver driving device 2 adopts electric pushrod, is connected with the venetian blind 3 being arranged on engine room ventilation mouth place; Described venetian blind controller 1 is connected with louver driving device 2; Described venetian blind controller 1 accesses blower fan automatic fire extinguishing system alarm signal, accesses temperature sensor signal in cabin simultaneously.Whole venetian blind control system is arranged in engine room inside.
Working procedure of the present invention is: after automatic fire extinguishing system confirms breaking out of fire, fire alarm signal is sent by automatic fire extinguishing system, venetian blind control system starts immediately after receiving fire signal, the venetian blind controlling ventilated port place, cabin closes 3 and closes, make the environment that in cabin, formation one is closed, after this automatic fire extinguishing system spurts extinguishing medium, complete putting out engine room inside burning things which may cause a fire disaster, after continuing for some time, the venetian blind 3 that venetian blind control system controls ventilated port place, cabin is opened, release cabin internal residual gas, so that personal security enters cabin and checks.
The present invention can also arrange by venetian blind controller 1 the cabin interior temperatures value that venetian blind 3 opens, closes.Without under the prerequisite of fire alarm, when the temperature value that cabin interior temperatures sensor obtains reaches the temperature settings that venetian blind 3 opens or close, venetian blind control system controls unlatching or the closedown that louver driving device 2 realizes venetian blind 3.
Claims (2)
