Technical field
The utility model relates to thermal power generation and nuclear electric power generation field, especially a kind of can thermal power plant's wind deflector of cooling tower of adjusting angle automatically.
Background technology
The cooling tower of present fuel-burning power plant all adopts hyperbolic curve profile, and turriform is higher.Due to upper and lower air pressure difference, just there is wind to enter at the bottom of tower, flow out from tower top.Got in the middle part of water tower by hot water out from turbodynamo condenser and be injected into drops, water droplet falls, and cold wind rises, thus cools hot water, and heated air, makes the flowing of air in water tower faster, the better effects if of cooling hot water; Cooled water droplet drops in the pond at the bottom of tower and regains, and again squeezes into the condenser of turbodynamo, continues circulation.
At cooling tower lower circumference alternate installation rectangle lightweight stiff, it is made to look down approximate helically blade sheet, and wind deflector adjustable angle.The object installing wind deflector additional is to make airflow velocity faster, but often due to wind outside to change fixed wind deflector is not only had accelerate distinguished and admirable effect, can hinder on the contrary and distinguished and admirablely enter cooling tower smoothly.Facts have proved, the cooling tower having installed fixing wind deflector additional is at section energy-saving effect highly significant sometime, but annual total energy-saving effect is also not obvious, illustrate that wind deflector is conducive to accelerating distinguished and admirable good energy-conserving effect in period at wind direction, hinder distinguished and admirable in tower passing through when wind direction is unfavorable for accelerating distinguished and admirable.As can be seen here, if can accelerate the air velocity in water tower all the time, so the cooling effectiveness of hot water can increase substantially.
Prior art can be provided with wind deflector and then realize the quickening of wind speed in cooling tower bottom, thus makes hot water cooling for reflux at short notice, reaches the effect that water circulation is accelerated to a certain extent.
But, on the current technology, also do not realize the rotation of wind deflector so reach that wind speed in tower is maximum, hot water cooling velocity maximizes and the maximization of work efficiency, therefore at the bottom of tower, air inlet one week adjustable wind deflector of setting angle has very high practical value.
Prior art can not meet the needs of people, for the problems referred to above, the utility model aim to provide a kind of can thermal power plant's wind deflector of cooling tower of adjusting angle automatically.
For realizing this technical purpose, scheme of the present utility model is: a kind of can thermal power plant's wind deflector of cooling tower of adjusting angle automatically, at least comprise air velocity transducer and the outer wind direction and wind velocity sensor of tower in wind deflector fixed frame, rotation axis, wind deflector, track with teeth groove, motor, cooling tower; The side, vertical side of described wind deflector is rotationally connected by rotation axis and the peripheral wind deflector fixed frame of cooling tower body; Described motor is fixedly mounted on the opposite side of the vertical side of wind deflector, and is fixedly installed gear on the rotating shaft, and this gear is connected with a joggle with the teeth groove with the track of teeth groove; The outer wind direction and wind velocity sensor connection mode number converter of air velocity transducer and tower and then be transferred to angle demodulator through arithmetical unit, the final rotation controlling motor in described cooling tower.
As prioritization scheme of the present utility model, described wind deflector is provided with 30 ~ 50 in the periphery of cooling tower body, and wind deflector global shape is rectangle, arc or plate wing.Its material is light-high-strength resin or high strength canvas
Further, the height of described wind deflector is 0.45h < L < 0.8h, and length is 0.35h < L < 0.7h, and wherein h is cooling tower air inlet height; Angle at the bottom of wind deflector and tower between circumference plumb cut is 45 ° ~ 135 °.
Compared with prior art, the beneficial effects of the utility model are: the wind deflector of this automatic adjusting angle, wind deflector can be made according to outside wind vector to be in the angle allowing distinguished and admirable the best pass through all the time, by by wind deflector angular adjustment to optimum position, the air entered bottom cooling tower is promoted through the inner pressure reduction up and down of cooling tower, rotate in tower and accelerate to rise, accelerate air velocity, thus high-temperature water rate of temperature fall in quickening tower, improve condenser vacuum degree, reduce steam coal consumption, reach the object of energy-saving and emission-reduction.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 4, in the utility model embodiment, thermal power plant's wind deflector of cooling tower of adjustable-angle, at least comprises air velocity transducer and the outer wind direction and wind velocity sensor of tower in wind deflector fixed frame 1, rotation axis 2, wind deflector 3, track 4 with teeth groove, motor 5, cooling tower; The side, vertical side of described wind deflector 3 is rotationally connected by rotation axis 2 and wind deflector fixed frame 1; Described motor 5 is fixedly mounted on the opposite side of the vertical side of wind deflector, and is fixedly installed gear on the rotating shaft, and this gear is connected with a joggle with the teeth groove with the track 4 of teeth groove; The outer wind direction and wind velocity sensor connection mode number converter of air velocity transducer and tower and then be transferred to angle demodulator through arithmetical unit, the final rotation controlling motor in described cooling tower.
As prioritization scheme of the present utility model, described wind deflector 3 is provided with 30 ~ 50 in cooling tower body periphery, and wind deflector global shape is rectangle, arc or plate wing.Its material is light-high-strength resin or high strength canvas
