The positive pole of the storage battery G1 is connected with the control power input end of the relay K9 of the signal generator through a lead. The control power output end relay K9 normally open contact end of the signal generator, the cathode of the storage battery G1 and the power input two-end relay K8 control power input end of the generator open-circuit and short-circuit detection mechanism and the cathode power input end of the relay K4 are respectively connected through leads. Two poles of a power supply of the storage battery G1, two terminals of two metal sheets T1 and T2 and pins 1 and 2 of a short message module A5 at two power input ends of the short message prompting circuit are respectively connected through leads. The normally closed contact ends of the pins 1 and 2 of the photoelectric switch A1 at the positive and negative pole power input ends and the relay K at the signal output end of the three photoelectric detection switches of the blade detection mechanism are respectively connected with the inner side ends of three slip rings X1, X2 and X3 through leads.

And the power output end of the wind power generation body M1 is connected with the four control power input ends of a relay K of the generator open-circuit and short-circuit detection mechanism through leads. Four normally closed contact ends of a control power output end relay K of the generator open-circuit and short-circuit detection mechanism are connected with electric equipment of the wind power generation body M1 through leads.
As shown in fig. 1 and 2, the solar cell panel G is illuminated by light to generate electric energy to charge the storage battery G1, so that the requirement of a working power supply of a rear-stage circuit is met. The wind driven generator body M1 is acted by wind to generate electric energy at ordinary times, so that an alternating current power supply (such as 220V) output by a live wire and a zero wire of a three-phase four-wire (such as 380V) enters two power input ends of the relay K8 through the diode VD, and the relay K8 is electrified to pull in the control power input end and the normally closed contact end to open a circuit. Because the positive pole (via the relay K9 normally open contact end) of the storage battery G1 is connected with the control power input end of the relay K8, and the relay K8 normally closed contact end is connected with the positive power input end of the generator open-circuit and short-circuit detection mechanism, when the generator body M1 normally generates electricity and does not break down, the generator open-circuit and short-circuit detection mechanism cannot work with electricity. Two poles of a power supply output by the storage battery G1 enter two power supply input ends of the blade detection mechanism through two metal sheets T1 and T2, wherein two slip rings X1 and X2 enter the two power supply input ends of the blade detection mechanism (when the generator body M1 is blown by wind to rotate by blades, three slip rings X1, X2 and X3 rotate, three metal sheets T1, T2 and T3 do not rotate and are respectively kept in an electric contact state with the three slip rings X1, X2 and X3, the normally closed contact ends of the three relays K, K1 and K2 and the 3 pins (the other ends of the resistor R1) of the short message module A5 are communicated through the slip rings X3 and the third metal sheet T3), so that the blade detection mechanism is in an electric working state (meanwhile, a 12V power supply output by the storage battery G1 enters the two power supply input ends of the short message prompting circuit, and the short message prompting circuit is electrified to work). When three blades of the wind driven generator body M1 do not fall off, the probe heads of three photoelectric switches A, A1 and A2 are shielded by the probe heads, 3 pins of the probe heads output high levels to respectively enter the positive power input ends of three relays K10, K1 and K2, so that the three relays K10, K1 and K2 are respectively electrified to attract the control power input end and the normally closed contact end of the three relays to be open, and 3 pins of a short message module A5 cannot be input with a trigger signal. In practical situations, as long as one blade 101 falls off, the 3 feet of any one of the photoelectric switches a or a1 and a2 stop outputting high level because no shielding object is arranged in front of the detecting head, and then the control power input end and the normally closed contact end of the relay K10 or K1 and K2 lose power are closed, so that after the control power input end (connected with the cathode of the storage battery G1) and the normally closed contact end of any relay K10 or K1 and K2 lose power are closed, low level is reduced voltage and limited current by the resistor R1 to enter the 3 feet of the short message module a5, so that the short message module a5 sends out the pre-stored short message "blade falling off" under the action of the internal circuit thereof, and after receiving the short message by a mobile phone of a manager connected with the short message module a5, the manager can intuitively know that the blade falling off phenomenon of the generator body M1 occurs on site, and timely and pertinently remove the fault of the wind driven generator body on site, and the normal work of the generator body is recovered as soon as possible.
As shown in fig. 1 and 2, when the wind driven generator body M1 fails and does not generate power, the relay K8 loses power and the control power input end and the normally closed contact end are closed, so that the generator open-circuit and short-circuit detection mechanism is in a power-on working state. Under the actual condition, when the surrounding environment has wind, wind-force signal generator M sends electric energy and gets into relay K9 power input both ends, then, relay K9 gets electric actuation its control power input end and normally open contact end closed, because relay K8's control power input end and relay K9's normally open contact end are connected, so when the surrounding environment has wind, relay K8's control power input end just can get electric, and then, the generator is opened a way and short circuit detection mechanism gets electric. When the surrounding environment is windless, the wind power signal generator M enters two ends of the power input of the relay K9 due to no power generation, then, the relay K9 loses power and no longer attracts to open the circuit of the control power input end and the normally open contact end, and because the control power input end of the relay K8 is connected with the normally open contact end of the relay K9, when the surrounding environment is windless, the control power input end of the relay K8 cannot get power, and therefore, the generator is opened and the short circuit detection mechanism cannot get power. Through the circuit function, when the generator body M1 fails and does not generate electricity, and the surrounding environment is windy, the generator open circuit and short circuit detection mechanism can work under electricity; the unnecessary power-on work of the generator open-circuit and short-circuit detection mechanism (the generator body M1 has no fault, and only no power generation is caused by no wind on the spot) due to no wind on the spot is prevented, and the unnecessary detection is carried out on the performance of the generator body M1.
As shown in fig. 1 and 2, when the generator body M1 is not in fault, after the generator open-circuit and short-circuit detection mechanism is powered on to operate, the relay K (actually, a contactor can be adopted) is in a power-off state, so that the power output by the generator body M1 enters a power supply line through four control power input ends and four normally closed contact ends of the relay K, and the power supply is used for normally supplying power to electrical equipment. When generator body M1 breaks down, the power positive pole of relay K8 normally closed contact end output can get into relay K and time control switch A4's anodal power input end, then, relay K gets electric actuation its four control power input ends and four normally closed contact ends open a way respectively, like this, prevented if the consumer end adopts interim stand-by power, four power output ends of generator body M1 are flowed back to the power, and then bring the influence to the normal work that the generator was opened a way and short circuit detection mechanism. Under the 3 and 4 foot output power time effects that time switch A4 got electric work back internal circuit and technical staff set for, can interval 3 seconds output power gets into relay K4 power input both ends, then relay K4 gets electric actuation its control power input end and normally open contact end closure, and the anodal power of battery G1 can get into the zero line of the three-phase four-wire power of generator body M1 through relay K4 control power input end and normally open contact end like this. In practical situations, when a serious fault occurs in the wind driven generator body M1, an internal coil is directly grounded with a self shell after being burnt, and the like, the positive power supply of the storage battery G1 can be directly subjected to voltage reduction and current limitation through the shell through the resistor R5 to enter the base of the NPN triode Q1, the NPN triode Q1 is conducted with the collector to output a low level to enter the 7 th pin of the short message module a5, so that the short message module a5 can send out a pre-stored short message short circuit under the action of an internal circuit thereof, and a manager connected with the short message module a5 can directly know that the generator body M1 coil short circuit occurs on site after receiving the short message through a mobile phone, so that the manager can timely and pertinently remove the fault of the wind driven generator body on site, and restore the normal operation of the generator body in the. After the relay K4 is electrified, the positive pole of the power supply input by the zero line of the generator body M1 can also enter the positive power supply input ends of three relays K5, K6 and K7 through three phase lines respectively, and the three relays K5, K6 and K7 are electrified to attract the power supply input ends and the normally closed contact ends to be open. Because the control power input ends of the relays K5, K6 and K7 are connected with the cathode of the storage battery G1, and the normally closed contact ends of the relays K5, K6 and K7 are connected with the pins 4, 5 and 6 of the short message module a5 respectively (the resistors R2, R3 and R4 reduce voltage and limit current), as long as any phase line is open, the relay K5, K6 and K7 lose power and no longer attract the control power input end and the normally closed contact end to be communicated, so that the pin 4, pin 5 and pin 6 of the short message module a5 can be input with a low level signal, the short message module a5 can send out the prestored short message "open phase line of the first phase line" or open phase line of the second phase line "and open phase line of the third phase line" under the effect of its internal circuit, and the manager connected with the short message module a5 can know that the first or second and third phase lines are open circuit on site visually after receiving the short message, managers can timely and pertinently get rid of the faults of the wind driven generator body on site, and the normal work of the generator body is recovered as soon as possible. In the invention, taking the wind driven generator body M1 as an example of three-phase four-wire 380V power generation, only a single phase wire of a power supply which normally generates three phase wire outputs enters the relay K5 or K6 or K7, so that the relay K5 or K6 or K7 cannot be electrified. In fig. 2, the resistances of the resistors R1, R2, R3, R4 and R5 are 10K; relays K, K10, K1, K2, K4, K5, K6, K7, K9 are DC12V relays; relay K8 is an ac 110V relay; the model of the diode VD is 1N4001 (the diode VD mainly plays a role in one-way conduction, and the 12V power supply anode is prevented from directly entering the power supply input end of the relay K7 through the relay K8 control power supply input end and the normally closed contact end, so that whether the third phase line of the generator body M1 is open or not can not be detected); NPN transistor Q1 model 9013.
