Also without power output fan main shaft.
Spiral type wind blade outside wind speed be more than 5m/s (fresh breeze) when, along with cooling tower itself discharge wind energy
(general wind speed be 8m/s, strong breeze), in the presence of variable-speed bearing so as to which main shaft is with higher than the rotating speed of spiral type wind blade
Rotate, and also above the rotating speed of blower fan main shaft, now spiral type wind blade rotating speed rises to equal with rotation speed of fan or more than wind
The rotating speed of owner's axle, in the presence of freewheel clutch, spiral type fan blade main shaft and blower fan main shaft are engaged, spiral type fan blade main shaft
Power is exported to blower fan main shaft.
The energy-saving cooling tower drive mechanism of described many power mixing, wherein, the appropriate position above first axle bed
Put, a belt wheel is fixed on the blower fan main shaft.Appropriate location above the belt wheel, the blower fan passes through bonded side
Formula is fixed on the blower fan main shaft.The blower fan main shaft is tightened with bolt with flange method and couples double rolling key clutch.
The second fixed support that fixed shaft is acted on has been arranged in position, it is fixed on second fixed support
Second axle bed；An axially extending bore is opened up on second axle bed, the main shaft of the spiral type wind blade passes through the through hole；
The upper and lower of the through hole is respectively arranged a upper taper roll bearing and lower taper roll bearing；The upper end of the through hole
A upper end cover is fixed, a bottom end cover is fixed in the big lower end of through hole, and bearing is clipped between end cap and the shaft shoulder of blower fan main shaft, made described
Spiral type wind blade is arranged on second axle bed.
Wherein, the spiral type fan blade main shaft couples double rolling key clutch in bonded mode.
The spiral type wind blade rotates under the drive of wind-force, and power is passed to institute by variable-speed bearing
Wind blade main shaft is stated, after rotating speed increase fan main shaft is exported again, make the blower fan make continuous rotating motion.
In the circulation of general central air-conditioning, in the case where circulating water flow reaches requirement, there is provided power
The lift that provided of water pump typically can be required for than cooling tower actual lift it is big by more than 30%.In general cooling tower,
This portion of energy having more can be wasted.The hydraulic turbine in the present invention can be converted into blower fan and rotate this portion of energy

The operation principle of energy-saving cooling tower drive mechanism of many power mixing of the embodiment of the present invention is：Driving machine of the present invention
The operating of the power drive blower fan 4 that structure is mainly provided with spiral type fan blade 3 and the hydraulic turbine 1, after the superposition output of both heres
During underpower, then it is aided with standby motor generator 2；When wind speed is too low, the rotating speed of blower fan 4 is less than the dynamic duty rotating speed needed for it
When, standby motor generator 2 can operate as motor work process auxiliary drive blower fan 4 so as to which rotating speed meets cooling tower normal work
It is required；When wind speed is sufficiently high, when energy be enough to maintain the normal work of blower fan 4 and have more than needed, motor generator 2 can be used as electromotor
Generate electricity and be stored in accumulator using power surplus；When wind speed it is too high, when the rotating speed of motor generator 2 is too fast, vertical-shaft wind
Electromotor deceleration device 14 reduces the rotating speed of spiral type fan blade 3 by way of increase windage, is reduced to the rotating speed of motor generator 2
Normal range of operation, it is to avoid cause the damage of motor generator 2.
The power surplus that the normal operation of the hydraulic turbine 1 is produced can be input on blower fan main shaft 5 by impeller 7, and blower fan main shaft 5 is again
Mechanical energy is delivered on blower fan 4 and drives blower fan 4 to operate.
Spiral type fan blade 3 has larger wind area, can also start operating under extremely low wind speed, and when working without

When the wind-engaging of spiral type fan blade 3 starts, spiral type fan blade 3 is passed moment of torsion by variable-speed bearing 18 and plain bearing 21
It is delivered on spiral type fan blade main shaft 17, due to the operating characteristic of variable-speed bearing, the fan blade main shaft being installed on variable-speed bearing inner ring
17 will obtain larger acceleration, to rotate higher than the speed of the rotating speed of fan blade 3 so that the rotating speed of fan blade main shaft 17 is in relatively low wind
Also higher than the rotating speed of blower fan main shaft 5 and by double rolling key clutch 13 blower fan main shaft 5 can be driven to rotate under speed, so as to blower fan 4 more
Required Dynamic Speed is easily reached, wind energy is utilized effectively.
When still reaching to less than required Dynamic Speed under driving of the blower fan 4 in fan blade 3 and the hydraulic turbine 1, PLC will be controlled
Motor generator processed 2 is exported as motor compensating, makes blower fan reach required Dynamic Speed.
When blower fan 4 is when the driving of fan blade 3 and the hydraulic turbine 1 is issued to required Dynamic Speed and has energy to have more than needed, PLC controls
Device processed will control motor generator 2 and collect as electromotor and this portion of energy is stored in accumulator；When wind speed it is excessive, it is electronic
Electromotor 2 exceed required Dynamic Speed when, vertical axis aerogenerator deceleration device 14 to increase windage in the way of reduce fan blade 3
Rotating speed, so as to Dynamic Speed needed for controlling the rotating speed of motor generator 2 not higher than, it is to avoid motor generator 2 is damaged.
In the circulation of general central air-conditioning, in the case where circulating water flow reaches requirement, there is provided power
The lift that provided of water pump typically can be required for than cooling tower actual lift it is much larger.In general cooling tower, have more
This portion of energy can waste.The hydraulic turbine in the present invention can be converted into the dynamic of blower fan rotation this portion of energy
Power, the normal operation for blower fan provides a part of power, so as to realize the recovery of the too high energy having more of pump bigcatkin willow journey.Recirculated water
After power is provided, then flows into water-locator from axial outlet outflow water turbine and go sprinkling.
The driving force that wind energy and the energy of hydraulic turbine conversion are preferentially used as blower fan of the invention.When the size of outdoor wind-force
When different, motor generator can play the part of different roles, when the power that the hydraulic turbine and spiral type wind blade are provided jointly can not
When meeting the required Dynamic Speed of blower fan, motor generator compensates partial power as motor, makes blower fan reach required dynamic
Rotating speed.When the power that the hydraulic turbine and spiral type wind blade are provided jointly disclosure satisfy that more than the required Dynamic Speed and power of blower fan
When measuring sufficiently large, motor generator into electric energy exports power allowance conversion and be stored in accumulator as electromotor.
Summary, the energy-saving cooling tower drive mechanism of this many power mixing passes through the power surplus of hydraulic turbine recovered water pump
Collect outdoor wind energy and be converted into the power that blower fan operates with spiral type wind blade is passed through, so that dynamoelectric and power generation
The energy consumption of machine is reduced, or even is allowed to generate electricity, and improves the utilization ratio of energy.
Embody energy-conservation, it is economical the characteristics of, increasingly focus on the society of environmental protection in today, the present invention has good
Use value and it is widely applied prospect.
A kind of energy-saving cooling tower drive mechanism of many power mixing, mainly including the hydraulic turbine, motor generator, spiral type wind
