[0019] Figure 1 , 2As shown, the outer diameter of the movable door 7 is larger than the outer diameter of the inlet and outlet 5. When the sealing gasket 6 at the rear side of the movable door 7 and the front side of the inlet and outlet are in contact, the movable door 7 and the front side of the inlet and outlet 5 are in tight sealing contact. The detection mechanism includes a magnet CT and a reed switch GH. A fixed rod 8 is vertically welded to the right front side of the lower end of the material chamber 2. The magnet CT is glued to the lower part of the fixed rod 8. The reed switch GH is vertically glued to the middle of the left front end of the cylinder of the electric push rod M1 at the right front end of the bottom plate 1. The moving contact of the reed switch GH is located on the left and the static contact is located on the right. The right side of the magnet CT and the left side of the reed switch GH are 1 mm apart and are in the same vertical plane. The reed switch GH is a normally closed contact reed switch. A normally closed contact button power switch AD1 is glued in front of the material chamber at the middle of the right end of the inlet and outlet, and the front end of the button of the power switch AD1 is 3 mm ahead of the front end of the material chamber 2. A baffle 9 is welded in the middle of the right end of the movable door. When the movable door is closed, the baffle just presses the button of the power switch AD1, and the internal contact of the power switch AD1 is open. The two terminals of the reed switch GH and the two terminals of the power switch AD1 are respectively connected between one of the normally open contact ends of the relay K1 and the positive power input end of the electric push rod M1, and between one of the normally open contact ends of the relay K2 and the positive power input end of the motor reduction mechanism M2. The first set of control circuits includes a resistor R1 and an NPN transistor Q1, a relay K1, and a power switch S3 connected via circuit board wiring, the positive power input terminal of the relay K1 is connected to one end of the power switch S3, the other end of the power switch R3 is connected to the positive control power input terminal of the relay K1, one end of the resistor R1 is connected to the base of the NPN transistor Q1, the collector of the NPN transistor Q1 is connected to the negative power input terminal of the relay K1, and the emitter of the NPN transistor Q1 is connected to the negative control power input terminal of the relay K1. The electric push rod M1 can also be replaced by a hydraulic cylinder. The second control circuit includes a resistor R2 and an NPN transistor Q2, a relay K2, and a power switch S4 connected via circuit board wiring. One end of the power switch S4 is connected to the positive power input end of the relay K2, and the other end of the power switch S4 is connected to the positive control power input end of the relay K2. One end of the resistor R2 is connected to the base of the NPN transistor Q2, the collector of the NPN transistor Q2 is connected to the negative power input end of the relay K2, and the emitter of the NPN transistor Q2 is connected to the negative control power input end of the relay K2.

[0020] Figure 1 , 2As shown, the two poles of the battery G2 and the two poles of the solar panel G2, the positive power input terminals of the relays K1 and K2 at both ends of the power input of the two control circuits, the 1 and 2 pins of the power input terminals of the two power switches S1 and S2, and the 1 and 2 pins of the power input terminals of the two rain sensors A2 and A3 are connected via wires. The power output terminals 3 and 4 of the two power switches S1 and S2 are connected via wires to the positive and negative power input terminals of the four electric push rods M1 and the positive and negative power input terminals of the motor reduction mechanism M2. The two normally open contact terminals of the power output terminals of the two control circuits, the positive and negative power input terminals of the four electric push rods M1, and the positive and negative power input terminals of the motor reduction mechanism M2 are connected via wires. The signal input terminals of the two rain sensors A2 and A3 are connected via wires.

[0021] The output pin 3 and the other ends of the signal input resistors R1 and R2 of the two control circuits are connected via wires. The handles of the power switches S1, S2, S3, and S4 are all located outside the front opening of the component box 10.

[0022] Figure 2 Among them, the battery G2 is a lithium battery of model 24V / 100Ah; the solar panel G1 is model 24V / 5Ah; the resistance of resistors R1 and R2 is 4.7K; the relays K1 and K2 are DC24V; the NPN transistors Q1 and Q2 are model S9013; the reed switch GH is a reed switch at the normally closed contact end of the glass shell; the electric push rod M1 is a high-power 280W reciprocating electric telescopic rod finished product; the rain sensors A2 and A3 are finished rain sensors of model B84285 (two power input terminals and one signal output terminal), which have a split rain detection head. After the detection head detects water, the rain sensor signal output terminal outputs a high level, otherwise it does not output; the motor reduction mechanism M1 is a coaxial motor gear reducer finished product with a working voltage of DC 24V and a power of 120W, and the power output shaft rotates at 6 revolutions per minute.

[0023] Figure 1 , 2As shown, the solar panel G1 generates electricity to charge the battery G2 under the sunlight. In this way, the new type does not need to set up power lines, which brings convenience to construction and installation, and saves energy accordingly. After it rains on site, after the two contacts of the detection surface of the rain sensor A3 are submerged by rainwater, the signal output terminal 3 of the rain sensor A3 will output a voltage signal and enter the other end of the resistor R2, and enter the base of the NPN transistor Q2 through the voltage reduction and current limiting of the resistor R2. The NPN transistor Q2 conducts and outputs a low level to the negative power input terminal of the relay K2. Therefore, the relay K2 is energized to attract its control power input terminal and the normally open contact terminal to close. In this way, the positive and negative power input terminals of the motor reduction mechanism M2 are energized, and the power output shaft of the motor reduction mechanism M2 drives the movable door to rotate counterclockwise, and the movable door 7 is gradually closed. When the movable door 7 is completely closed and the rear side end is in contact with the sealing gasket 6, the movable door 7 is in close sealing contact with the front side of the inlet and outlet 5. In this way, the external rainwater will no longer enter the material room 2. After the movable door is closed, the button of the power switch AD1 is pressed by the right end of the inner side of the baffle of the movable door, and its internal contact is open. Since the two terminals of the power switch AD1 are connected between one of the normally open contact terminals of the relay K2 and the positive power input terminal of the motor reduction mechanism M2 through a wire, the motor reduction mechanism M2 will lose power and no longer work at this moment, preventing the movable door from rotating uncontrollably counterclockwise and causing the motor reduction mechanism to work abnormally. Later, when the staff arrives at the site and needs to open the movable door 7, they turn off the power switch S4, the positive power input terminal of the relay K2 loses power, and then turn on the power switch S2. In this way, the negative and positive power input terminals of the motor reduction mechanism M2 get the electrical power output shaft to drive the movable door to rotate clockwise, and the movable door gradually opens. After the movable door is fully opened, the power switch is turned off.

[0024] Figure 1 , 2As shown, when the water on the ground does not flood the detection surface of the rainwater sensor A2, the 3rd pin of the rainwater sensor A2 does not output a high level, so the four electric push rods M1 will not push the material room to rise. When the water on the ground floods the detection surface of the rainwater sensor A2, the 3rd pin of the rainwater sensor A2 outputs a high level and enters the other end of the resistor R1, and enters the base of the NPN transistor Q1 through the voltage reduction and current limiting of the resistor R1. The collector of the NPN transistor Q1 is turned on and outputs a low level and enters the negative power input end of the relay K1. Therefore, the relay K1 is energized to attract its control power input end and the normally open contact end to close. In this way, the positive and negative power input ends of the four electric push rods M1 are energized, and the push rods of the four electric push rods M1 drive the material room 2 to rise, and the distance between the material room 2 and the water surface is widened to prevent water from entering the material room. When the rain sensor A2 at the lower end of the material room 2 detects a distance between the surface and the water, the 3rd pin of the rain sensor A2 no longer outputs a high level, and the four electric push rods M1 no longer receive power. When the four electric push rods M1 push the material room up to the dead point, the magnet CT is located at the left end of the reed switch GH, and the internal contact of the reed switch GH is open. Since the two terminals of the reed switch GH are respectively connected between one of the normally open contact ends of the relay K1 and the positive power input terminal of the electric push rod M1 through wires, at this moment, the electric push rod M1 will lose power and work, preventing the electric push rod M1 from working uncontrollably and being powered on all the time, causing damage to it. Later, when the staff arrives at the site and needs the material room 4 to be lowered, they turn off the power switch S3, the positive power input terminal of the relay K1 loses power, and then turn on the power switch S1. In this way, the negative and positive power input terminals of the four electric push rods M1 receive power, and the push rods drive the equipment room to descend. After the equipment room reaches a suitable height, the power switch is turned off. Through the above, the new device can automatically close the movable door at the first time when it rains on the site, and the electric push rod can automatically adjust the height of the high material room when the water on the road surface reaches a certain level, thereby reducing the adverse effects of rain on the materials as much as possible.
