Technical field the present invention relates to a kind of ventilating system of intelligent automatic control, especially a kind of smart wind control system of cooling tower that is applicable to thermal power station and nuclear power station use.
Background technology cooling tower is as the visual plant in heat power station circulating water cooling system, in use ubiquity as ambient temperature raises, wind-force is when larger, natural wind is directly blown over from running through at the bottom of tower, cooling tower inner bottom part and upper air convection circulation are weakened, cause stable eddy current or the air-flow dead state of the interior formation of larger space on cooling tower bottom and top, air circulation weakens, cause that cooling tower bottom tank water temperature raises, cooling effectiveness reduces, affect generating set the thermal efficiency, so increase energy resource consumption.
Summary of the invention the object of this invention is to provide a kind ofly can regulate according to the outer wind direction of cooling tower, wind speed and Ta Nei temperature the smart wind control system of cooling tower of ventilation state automatically.
For achieving the above object, smart wind control system of cooling tower provided by the invention in the space between cooling tower bottom pedestal and water leg along cooling tower shell lower outer week along being provided with the upper and lower grit being connected by uniform column, vertically through the deep bead central shaft of upper and lower grit, deep bead is arranged between two adjacent columns, the stepper motor being electrically connected to single-chip microcomputer is connected with deep bead central shaft by transmission mechanism, and the temperature, wind speed, the wind transducer that are arranged on cooling tower inside are electrically connected to single-chip microcomputer.Transmission mechanism between stepper motor and deep bead central shaft is connected with follow-up pulley by cable wire for the motive power bar coaxial with stepper motor, on the cable wire between motive power bar and follow-up pulley, be evenly equipped with leading block and gripper sleeve, slave arm one end is fixed in deep bead central shaft top, the other end is plugged in slave arm sliding sleeve, and slave arm sliding sleeve is connected with gripper sleeve by connecting rod.
Adopt after said structure, can be according to the data message of the temperature of cooling tower inside, wind speed, wind transducer transmission, through single-chip microcomputer, process, send instruction and start stepper motor, by transmission mechanism, deep bead central shaft is rotated, drive the corresponding angle of the synchronous rotation of deep bead, realize the in good time opening and closing of enclosure space that cooling tower bottom forms, thereby guarantee that cooling tower bottom and tower internal upper part keep the flow regime of air.After stepper motor starts, the gripper sleeve in transmission mechanism moves with cable wire, by connecting rod, the transmission of slave arm sliding sleeve, slave arm is rotated and drives deep bead central shaft to rotate freely with angle.
As a further improvement on the present invention, in slave arm sleeve, be provided with many built-in oil ducts.Can dose lubricant, avoid the generation of bite, wear phenomenon.
Feature of the present invention is: simple in structure, easy to use, by structure of modification is carried out in original cooling tower bottom, can automatically regulate deep bead opening angle according to extraneous wind direction, wind speed and temperature, optimize bottom inlet air intake, guarantee that in tower, the smooth and easy of wind direction flows, thereby improve the heat exchanger effectiveness of cooling tower, reduce energy consumption.
Description of drawings 1 is the overall structure schematic diagram of smart wind control system of cooling tower of the present invention.
Fig. 2 is for showing as Fig. 1 the structural representation that removes upper cover plate and control system.
Fig. 3 is for showing separate unit drive system structure schematic diagram as Fig. 1.
Fig. 4 is for showing structure enlarged drawing as Fig. 3.
The specific embodiment is described in further detail the present invention below in conjunction with accompanying drawing:
As shown in Figure 1, 2, smart wind control system of cooling tower of the present invention in the space between cooling tower 1 bottom pedestal and water leg along cooling column body bottom external week along being provided with the upper and lower grit 3,4 being connected by uniform column 2, vertically through the deep bead central shaft 5 of upper and lower grit, deep bead 6 is arranged between two adjacent columns, the stepper motor 8 being electrically connected to single-chip microcomputer 7 is connected with deep bead central shaft by transmission mechanism.The temperature, wind speed, the wind transducer 9 that are arranged on cooling tower inside are electrically connected to single-chip microcomputer.Transmission mechanism between stepper motor and deep bead central shaft is for to be connected (as Fig. 3 shows) with the motive power bar 10 of stepper motor coaxial rotation with follow-up pulley 12 by cable wire 11, on the cable wire between motive power bar and follow-up pulley, be evenly equipped with the leading block 13 of playing a supporting role and the gripper sleeve 14 of transferring power, slave arm 15 one end are fixed in deep bead central shaft top, the other end is plugged in slave arm sliding sleeve 16, and slave arm sliding sleeve is connected with gripper sleeve by connecting rod 17.Gripper sleeve, along with cable wire moves, rotates slave arm by connecting rod, the transmission of slave arm sliding sleeve and drives deep bead central shaft to rotate freely with angle, be processed with many built-in oil ducts in slave arm sleeve, plays lubrication (as Fig. 4 shows) in use.
In use, cooling tower bottom can be divided into as dry group according to nature wind direction, every group of interior a set of independent stepper motor, transmission system, deep bead etc. installed, whole system is controlled by a single-chip microcomputer is unified.Can be according to the data message of the temperature of cooling tower inside, wind speed, wind transducer transmission, through single-chip microcomputer, process, sending instruction startup stepper motor rotates deep bead central shaft by transmission mechanism, drive the corresponding angle of the synchronous rotation of deep bead, thereby guarantee that cooling tower bottom air inlet entrance is unimpeded, outlet sealing, and keep Convection states with tower internal upper part.For example: when extraneous wind direction is positive north wind, north deep bead is opened, and south orientation deep bead is closed, and certain angle is opened to deep bead in northeast, northwest, southwest, southeast deep bead are closed.Make extraneous natural wind from unidirectional the entering in cooling tower bottom, from top, discharge.
Certainly in actual use, cooling tower bottom can be divided into 8 groups, 10 groups, 12 groups etc. some groups by nature wind direction.Quantity is more, and effect is better.
It is simple in structure, easy to use that the present invention has, keeping in the immovable situation of original cooling tower structure, by peripheral structure design is carried out in cooling tower bottom, can by intelligence control system, automatically regulate deep bead opening angle according to extraneous wind direction, wind speed and variations in temperature, optimize bottom air inlet entrance and direction, guarantee wind direction smooth and easy flowing from bottom to top in tower, thereby improve the heat exchanger effectiveness of cooling tower, reduce energy consumption.
