pins

1 and 2 of the regulated power supply a1, the regulated power supply a1 outputs stable dc12V power under the action of its internal circuit, and enters the power input terminals of the rain detection circuit and the flooding detection circuit (simultaneously, outputs 12V dc power to float and charge the battery G), so that the circuits are in an electric working state. In the rainwater detection circuit, when the sky does not have rain, two sets of electric telescopic handle A's of closing mechanism piston rod is in the front dead point and drives closing plate 42 rear end and heat dissipation shell 44 front end and pull open the interval, fills the heat that this internal production of electric pile like this and can outwards give off through heat dissipation shell 44 front opening, like this, fills the part in the 3 shells of electric pile and can effectively obtain the heat dissipation. When raining, the two copper sheets T of the probe are submerged by rainwater, so that the positive electrode of a 12V power supply can be subjected to voltage reduction and current limitation through the resistor R1, water and the probe T enter the base electrode of the NPN triode Q, the NPN triode Q is conducted with the collector to output low level and enters the negative power supply input end of the relay K1, the relay K1 is electrified to attract the control power supply input end and the normally open contact end to be closed, and the control power supply input end and the normally closed contact end to be opened. Because the 3 feet of the time control switch A2 are connected with the normally open contact end of the relay K1, the time control switch A2 can be triggered by inputting a trigger signal at the moment, the 9 feet of the time control switch A2 can output 8 seconds of power to enter the positive power input end of the relay K2 under the action of the internal circuit of the time control switch A2 and the time of outputting power by the 9 feet set by a technician, so that the relay K2 is electrified to attract the two control power input ends and the two normally open contact ends of the relay K2 to be respectively closed, the positive and negative poles of two sets of electric telescopic rods AM are electrified, the piston rods of the two sets of electric telescopic rods AM drive the sealing plate 42 to move towards the rear side end to a rear dead point, the sealing rubber pad 43 at the rear side end of the sealing plate 42 and the front end of the heat dissipation shell 44 is in a tight contact state, and thus, rainwater can be effectively prevented from entering the shell of the charging pile (the rainwater is not heavy at the initial stage of raining just raining, and the upper end of the charging pile body can prevent rainwater from entering the shell, even if the rainwater is large when the sealing plate is closed, the rainwater is blown by wind and floats obliquely, and the rainwater cannot enter the shell). After the rain is stopped, no rain exists between the two copper sheets of the probe T, the two copper sheets T are not submerged by water, so that the positive electrode of the 12V power supply does not enter the base electrode of the NPN triode Q through the resistor R1 and the probe T, the NPN triode Q is cut off, the relay K1 is powered off, the control power supply input end and the normally open contact end are opened, and the control power supply input end and the normally closed contact end are closed. Because time switch A's 3 feet and relay K1's normally closed contact end are connected, time switch A can be input trigger signal and then trigger this moment, time switch A is under the 9 feet output power supply time effects that its internal circuit and technical staff set for, time switch A's 9 feet can export 8 seconds power and get into relay K's power input end, then relay K gets electric actuation its two control power input ends and two normally open contact ends are closed respectively, and then two sets of electric telescopic handle A negative and positive poles of the earth get electric its piston rod drive closing plate 42 forward side end once more and move to the front dead point, fill the heat that this internal production of electric pile once more can outwards give off through heat dissipation shell 44 front end opening again. Through the aforesaid, rainwater detection circuit can control at ordinary times and fill electric pile's shell rear end closing plate and open, like this, fill the part in the electric pile shell and can effectively obtain the heat dissipation, and when raining, the probe detects the back, and rainwater detection circuit can automatic control closing plate is closed backward, can also play the radiating effect for the shell inner part under the rain-proof prerequisite of assurance.

As shown in fig. 1, 2 and 3, in the water logging detection circuit, when the ground of the charging pile area has no or little accumulated water and the two copper sheets of the probe AT1 are not submerged, the piston rods of the four sets of electric telescopic rods M1 of the lifting mechanism are AT the lower dead point and drive the charging pile 3 to move downwards to the dead point, and the charging pile is AT the lowest height, so that the charging operation of a charger is facilitated. When the two copper sheets of the probe AT1 are submerged due to deep water level such as waterlogging or flood in the charging pile area, the two copper sheets AT1 of the probe are submerged by water, so that the positive electrode of a 12V power supply can be subjected to voltage reduction and current limitation through a resistor R2, the water enters the base electrode of an NPN triode Q1 through the probe AT1, the NPN triode Q1 is conducted with a collector electrode to output low level and enters the negative power input end of a relay K3, the relay K3 is electrified to attract the control power input end and the normally open contact end to be closed, and the control power input end and the normally closed contact end to be open. Because time switch A3's 3 feet and relay K3's normally open contact end are connected, time switch A3 can be input trigger signal and then trigger at this moment, time switch A3 is under the effect of its internal circuit and the 9 feet output power supply time that the technical staff set for, time switch A3's 9 feet can export 25 seconds positive pole power and get into relay K4's power input end, then relay K4 gets the electricity actuation its two control power input ends and two normally open contact ends closed respectively, and then four sets of electric telescopic handle M1 negative and positive two poles get electricity its piston rod promotion and fill electric pile whole rising height about 30 centimetres, effectively prevented that water from submerging shell inner member. When the ground accumulated water height is reduced (no potential safety hazard is caused to elements in the shell), the two copper sheets of the probe AT1 are not submerged by rainwater, the positive electrode of the 12V power supply does not enter the base electrode of the NPN triode Q1 through the resistor R2 and the probe AT1, the NPN triode Q1 is cut off, the input end of the control power supply and the normally open contact end of the relay K3 are powered off, and the input end of the control power supply and the normally closed contact end are opened and closed. Because the 3 feet of the time control switch A4 are connected with the normally closed contact end of the relay K3, the time control switch A4 can be triggered by inputting a trigger signal at the moment, the time control switch A4 outputs 25 seconds of power to enter the power input end of the relay K5 under the action of the internal circuit of the time control switch A4 and the time of the power output of the 9 feet set by a technician, then the relay K5 is electrified to pull in the two control power input ends and the two normally open contact ends of the relay to be respectively closed, and then the four sets of electric telescopic rods M1 are electrified to have the positive and negative poles thereof piston rods to drive the charging pile to integrally descend by about 30 centimeters to return to the initial position. Through the aforesaid, under the effect of flooding detection circuit, after filling the water level of ground around the electric pile and submerging probe AT1 to certain degree of depth, can fill electric pile's height through hoist mechanism automatic height-adjusting, ground ponding reduces to the height that electric pile was filled in automatically regulated low behind the certain degree, has made things convenient for AT ordinary times the person that charges under the prerequisite, can also effectively prevent to fill electric pile by the flooding.

As shown in fig. 1, 2 and 3, after the switching-off circuit is powered on to work, the depth of the local area water is high, two copper sheets of the probe a are submerged, and when the relay K3 is powered on, the power supply output by the normally open contact end of the relay K3 can also be reduced through the resistor R3 to reduce the voltage and limit the current to trigger the control electrode of the thyristor VS, so that the thyristor VS is triggered to be switched on, and then the relay K6 is powered on to attract the control contact end and the normally open contact end to be closed. Because, two contacts under relay K6 control contact end and normally open contact end and the experiment button S of the inside earth-leakage protector A5 who fills electric pile are connected through the wire respectively, so when ground water level was too high, earth-leakage protector A5 can trip, and then fills the whole outage of electric pile, has prevented like this that the flooding from resulting in the interior component of shell to damage or the trouble enlargements.
