As shown in fig. 1 and 2, the utility model is mounted on the upper end of a power supply iron tower or a power transformer and the like through a clamping groove 6 before use. When wind exists in a corresponding area at ordinary times, wind power drives the connecting rod 7, the motor speed reducing mechanism M1 and a rotating shaft of the alternating current generator M to rotate through the wind bowl 1, so that electric energy generated by the alternating current generator M is rectified by the rectifier bridge stack A1 and filtered by the capacitor C1 to charge the storage battery G1 (the diode VD1 plays a role of one-way conduction); the solar panel G2 generates electric energy to charge the storage battery G1 when being illuminated; through the aforesaid, this novel can realize that scene is complementary charges for battery G1, has prevented the single solar energy power supply that adopts, and on-the-spot illuminance can cause the drawback of the unable reliable power supply of whole equipment when not good. After the power supply output by the storage battery G1 enters the control circuit and the alarm circuit, the circuits are powered to work. This novel wind bowl drives generator M pivoted while still can drive the continuous 360 degrees rotations of microwave sensor A3 on connecting rod 7 upper portion, in the rotation of microwave sensor A3, wherein the inner circle of three bearings 8 rotates, the outer lane does not rotate, the power two poles of the earth of battery G1 output like this through the outer lane and the copper ball of first bearing and second bearing, the inner circle through first bearing and second bearing respectively gets into microwave sensor A3's power input end, the 3 feet of signal output part of microwave sensor A3 are through the inner circle of third bearing, the outer lane and the relay K3 negative pole power input end intercommunication of copper ball and third bearing 8. Through the aforesaid, this novel ability drives generator shaft rotation, generator M electricity generation at the wind bowl in, remains all the time that microwave sensor A3 gets electric work, realizes through 360 degrees rotations simultaneously that whether there is the flying bird to be close in no dead angle detection corresponding region.

As shown in fig. 1 and 2, when the motor speed reducing mechanism M1 rotates, the rotating shaft of the generator M rotates along the inner rings of the fourth and fifth bearings, the inner rings of the fourth and fifth bearings are communicated with the two ends of the power input of the motor speed reducing mechanism M1, and the inner rings of the fourth and fifth bearings are communicated with the two ends of the normally closed contact of the relay K1 through the balls and the outer rings. In practical situations, when wind exists on site, a power supply output by the wind driven generator M is rectified by a rectifier bridge stack A1 and filtered by a capacitor C1, the power supply is subjected to voltage reduction and current limiting through a resistor R1 and enters a base electrode of an NPN triode Q1, the NPN triode Q1 is conducted with a collector electrode, a low level is output and enters an input end of a negative electrode power supply of a relay K1, the relay K1 is electrified and closed, the input end of the control power supply and an end of a normally closed contact of the relay are opened, and then the motor speed reducing mechanism M1 cannot be electrified to work. In practical situations, when no wind or small wind is generated on site, because the wind driven generator M does not generate power any more or the generated electric energy is extremely low, the voltage of the base of the NPN triode Q1, which is dropped and limited by the resistor R1, is lower than 0.7V, the base of the NPN triode Q1 loses power, the NPN triode Q1 is cut off, the relay K1 loses power and does not attract the two control power input ends and the two normally closed contact ends of the NPN triode Q1 to be respectively closed, and thus the motor speed reduction mechanism M1 can be used as a power output shaft of the motor speed reduction mechanism M1 to drive the connecting rod 7 and the microwave sensor a2 to continue 960-degree rotation. Through the combined action of the circuits and the mechanisms, when wind exists on the site, the wind power drives the microwave sensor A2 to continuously rotate at 360 degrees without dead angles to detect whether flying birds enter a defense area, when wind does not exist on the site or the wind power is extremely small, the motor speed reducing mechanism M can continuously drive the microwave sensor A2 to detect whether flying birds enter the defense area in a 360-degree rotation mode, when wind exists on the site again, the relay K1 is electrified again to attract the control power supply input end and the normally closed contact end of the relay to be open again, and then the motor speed reducing mechanism M1 is electrified again to stop driving the microwave sensor A2 to rotate; wind power continuously drives the microwave sensor A3 to rotate continuously, and the microwave sensor A2 is effectively guaranteed to have no dead angle to detect a fortification area according to a 360-degree rotation mode. It should be noted that the speed of the microwave sensor A3 and the wind bowl driven by the power output shaft of the motor speed reducing mechanism M1 is very slow (10 revolutions per minute), the upper end of the casing of the motor speed reducing mechanism M1 is provided with a multi-stage gear speed reducing mechanism, when the wind power is large, the rotating speed of the connecting rod is more than 10 revolutions per minute, the wind power drives the motor speed reducing mechanism M1 and the rotating shaft of the generator M, the microwave sensor A3 to rotate, and because of the multi-stage speed reducing gear function of the motor speed reducing mechanism M1, the rotating speed of the power output shaft is slow but the torque is very large, so when the wind power is more than about 10 revolutions per minute, the wind power can effectively drive the motor speed reducing mechanism M1 and the generator M to rotate through the wind bowl; when the rotation speed is lower than about 10 revolutions per minute, the electric energy generated by the generator M is extremely low, the voltage of the base voltage entering the NPN triode Q1 is lower than 0.7V, the relay K1 cannot be electrified and attracted, then the motor speed reducing mechanism M1 can keep electrified to drive the microwave sensor A3 and the like to rotate, only when the field wind power is relatively large (the motor can drive the microwave sensor A3 and the like to rotate about 10 revolutions per minute), the electric energy generated by the generator M enters the base of the NPN triode Q1 and is higher than 0.7V, then the relay K1 is electrified and attracted, the control power supply input end and the normally closed contact end are opened, and further the wind power drives the microwave sensor A3 and the like to rotate.

As shown in fig. 1 and 2, in the present invention, when the microwave sensor a2 works, a microwave signal is transmitted to the circumferential 360-degree direction through the antenna X, and when no flying bird enters the front end of the microwave sensor a2 within a range of about 7 meters, the 3 pins of the microwave sensor A3 do not output a power signal, so the relay K3 is not powered on, and the buzzer B does not sound; when flying birds enter a detection range within 7 meters of the microwave sensor A3 in the circumferential direction, the 3 pins of the microwave sensor A3 can output low level to enter the negative electrode power input end of the relay K3, the relay K3 is powered on to pull the control power input end and the normally open contact end of the relay closed, and then the audible alarm B sends loud alarm sound to scare away the approaching birds. When the bird leaves the detection range of the microwave sensor A3, the 3-pin of the microwave sensor A3 stops outputting low level, and the buzzer B does not sound any more. The novel wind-solar hybrid flying bird repelling device has the advantages that the wind-solar hybrid charging is realized, the microwave sensor can detect approaching flying birds without blind areas, when the flying birds approach a detection area, loud alarm repelling sound can be sent out through the buzzer, a good flying bird repelling effect can be achieved, and the normal work of the whole device is guaranteed due to the fact that the solar energy and the wind power are used for bidirectional power supply. In fig. 2, the diode VD1 (unidirectional conduction action) model is 1N 4007; the resistance value of the resistor R is 470K; the model of the NPN triode Q1 is 9013; relays K1, K3 are DC4123 type 12V relays; the buzzer B is an active continuous sound high-decibel siren alarm finished product of electronic buildings in the brand and the model BJ-1; the model of the rectifier bridge stack A1 is DB 107; microwave sensor a3 model TWH 9250; the capacitor C1 is an electrolytic capacitor of type 470 muF/25V.
