Description
Affiliated technical field the present invention relates to a kind of ventilating system of intelligent automatic control, especially a kind of cooling tower intelligence control wind system that is applicable to that thermal power station and nuclear power station use.
The background technology cooling tower is as the visual plant in the heat power station circulating water cooling system; When in use ubiquity like ambient temperature rising, wind-force greatly; Natural wind directly runs through at the bottom of the tower blows over, and cooling tower inner bottom part and upper air convection circulation are weakened, and causes eddy current or the air-flow dead state stable than formation in the large space on cooling tower bottom and top; Air circulation weakens; Cause the tank water temperature rising of cooling tower bottom, cooling effectiveness to reduce, influence the thermal efficiency of generating set, and then increase energy resource consumption.
Summary of the invention the purpose of this invention is to provide a kind of cooling tower intelligence control wind system that can regulate automatically according to the outer wind direction of cooling tower, wind speed and Ta Nei temperature.
For achieving the above object; Cooling tower provided by the invention intelligence control wind system in the space between cooling tower bottom pedestal and the water leg along cooling tower shell lower outer week along being provided with the upper and lower grit that is connected through the column that is uniformly distributed with; Vertically deep bead is arranged between the two adjacent columns through the central shaft of upper and lower grit; Be connected with the deep bead central shaft through transmission mechanism with the stepper motor that single-chip microcomputer is electrically connected, be arranged on cooling tower temperature inside, wind speed, wind transducer and be electrically connected with single-chip microcomputer.
After adopting said structure; Can handle through single-chip microcomputer according to the data message of cooling tower temperature inside, wind speed, wind transducer transmission, send instruction and start stepper motor; Make the rotation of deep bead central shaft through transmission mechanism; Drive deep bead and rotate corresponding angle synchronously, realize the in good time opening and closing of enclosure space that the cooling tower bottom forms, thereby guarantee that cooling tower bottom and tower internal upper part keep the flow regime of air.
Transmission mechanism between said stepper motor and the deep bead central shaft is for to be connected with follow-up pulley through cable wire with the coaxial motive power bar of stepper motor; On the cable wire between motive power bar and the follow-up pulley, be evenly equipped with leading block and gripper sleeve; One end is fixed in the slave arm at deep bead central shaft top; Its other end is plugged in the slave arm sliding sleeve, and the slave arm sliding sleeve is connected with gripper sleeve through connecting rod, is provided with many built-in oil ducts in the slave arm sleeve.Can dose lubricant, avoid the generation of bite, wear phenomenon.After stepper motor started, gripper sleeve moved with cable wire, made slave arm rotate drive deep bead central shaft through connecting rod, the transmission of slave arm sliding sleeve and rotated freely with angle.
Characteristics of the present invention are: simple in structure, easy to use; Through structure of modification is carried out in original cooling tower bottom; Can regulate the deep bead opening angle automatically according to extraneous wind direction, wind speed and temperature, optimize the bottom inlet air intake, guarantee that the smooth and easy of wind direction flows in the tower; Thereby improve the heat exchanger effectiveness of cooling tower, cut down the consumption of energy.
Description of drawings Fig. 1 is the overall structure sketch map of cooling tower intelligence control wind system of the present invention.
Fig. 2 is for showing the structural representation that removes upper cover plate and control system like Fig. 1.
Fig. 3 is for to show separate unit drive system structure sketch map like Fig. 1.
Fig. 4 is for to show the structure enlarged drawing like Fig. 3.
The specific embodiment is done further explain below in conjunction with accompanying drawing to the present invention:
Like Fig. 1, shown in 2, cooling tower of the present invention intelligence control wind system in the space between cooling tower 1 bottom pedestal and the water leg along cooling tower shell bottom external week along being provided with the upper and lower grit 3,4 that is connected through the column 2 that is uniformly distributed with.Vertically deep bead 6 is arranged between the two adjacent columns through 5 of upper and lower grit.The stepper motor 8 that is electrically connected with single-chip microcomputer 7 is connected with the deep bead central shaft through transmission mechanism.Being arranged on cooling tower temperature inside, wind speed, wind transducer 9 is electrically connected with single-chip microcomputer.Transmission mechanism between stepper motor and the deep bead central shaft is for to be connected (showing like Fig. 3) with the motive power bar 10 of stepper motor coaxial rotation through cable wire 11 with follow-up pulley 12; On the cable wire between motive power bar and the follow-up pulley, be evenly equipped with the gripper sleeve 14 of leading block of playing a supporting role 13 and transferring power; One end is fixed in the slave arm 15 at deep bead central shaft top; Its other end is plugged in the slave arm sliding sleeve 16, and the slave arm sliding sleeve is connected with gripper sleeve through connecting rod 17.Gripper sleeve makes slave arm rotate drive deep bead central shaft through connecting rod, the transmission of slave arm sliding sleeve and rotates freely with angle, be processed with many built-in oil ducts in the slave arm sleeve along with cable wire moves, and plays lubrication (showing like Fig. 4) in the use.
In use, can the cooling tower bottom be divided into some groups according to the nature wind direction, the every group of interior independent stepper motor of a cover, transmission system, deep bead etc. installed, whole system is by the unified control of a single-chip microcomputer.Can be according to the data message of cooling tower temperature inside, wind speed, wind transducer transmission; Handle through single-chip microcomputer; Send instruction startup stepper motor and make the rotation of deep bead central shaft through transmission mechanism; Drive deep bead and rotate corresponding angle synchronously, thereby guarantee that cooling tower bottom air inlet inlet is unimpeded, the outlet sealing, and keep stream mode with the tower internal upper part.For example: when extraneous wind direction was positive north wind, the north deep bead was opened, and deep bead in the south is closed, and certain angle is opened to deep bead in northeast, northwest, and southwest, southeast deep bead are closed.Make extraneous natural wind from the cooling tower unidirectional entering in bottom, discharge from the top.
Certainly in actual use, can cooling tower bottom be divided into 8 groups, 10 groups, 12 groups etc. some groups by the nature wind direction.Quantity is many more, and effect is good more.
It is simple in structure, easy to use that the present invention has; Keeping under the immovable situation of original cooling tower structure,, can regulate the deep bead opening angle automatically through intelligence control system according to extraneous wind direction, wind speed and variations in temperature through the peripheral structure design is carried out in the cooling tower bottom; Optimize bottom air inlet inlet and direction; Guarantee wind direction smooth and easy flowing from bottom to top in the tower, thereby improve the heat exchanger effectiveness of cooling tower, cut down the consumption of energy.
