It includes a DC power supply, a first timing module M1, a delay module M2, a second timing module M3, a lifting motor control module M4, an automatic control valve control module M5, a rotating motor control module M6 and a light emitting module M7.

Wherein, the lifting motor control module M4 is respectively connected with the first timing module M1, the second timing module M3 and the automatic control valve control module M5. The delay module M2 is connected to the first timing module M1 and the rotating motor control module M6 respectively.

The first timing module M1, the delay module M2, the second timing module M3, the lifting motor control module M4, the automatic control valve control module M5, the rotating motor control module M6 and the light emitting module M7 are all connected to the DC power supply.

The first timing module M1 is used for timing and periodically giving an electric signal to the automatic control valve 17 to close the valve and delay start the lifting motor 331 to work. The delay module M2 is used to control the working time of the rotating motor 3331 . The second timing module M3 periodically gives a reverse signal to the lifting motor 331 . The lifting motor control module M4 is a control module of the lifting motor 331, and the electric signals from the first timing module M1 and the second timing module M3 control the forward and reverse rotation of the motor. The automatic control valve control module M5 is a control module of the automatic control valve 17, and the opening and closing of the automatic control valve 17 is controlled by electric signals from the first timing modules M1, M2 and M3. The rotary motor control module M6 is a control module of the rotary motor 3331, and the operation of the rotary motor 3331 is controlled by the electric signal from the delay module M2. The light-emitting module M7 is a light-emitting circuit composed of light-emitting diodes. Referring to FIG. 5 , the first timing module M1 uses a 555 timer to build a square wave output circuit with an adjustable duty cycle. The 4 and 8 pins of the 555 chip are connected to the power supply, the 1 and 5 pins are grounded as required, and the 3 pins are used as the output terminal of the square wave signal, and the output of the 3 pins is controlled by the potential conditions of the 2 and 6 pins. On the premise that the capacitor C7 has no electricity, the power supply Vcc charges C7 through R6 and the upper part of RP2 through D5. It can be seen from the figure that the potential of pins 2 and 6 is controlled by the voltage at both ends of C7. Since the voltage at both ends of the capacitor cannot be changed instantaneously, C7 just turns on When charging, pins 2 and 6 are at low level, both less than 1/3Vcc, so pin 3 outputs high level. When the voltage across C7 is greater than 1/3Vcc and less than 2/3Vcc, pin 3 keeps outputting the previous state (in this language logic, pin 3 outputs high level). When the voltage across C7 exceeds 2/3Vcc, pin 3 outputs a low level, and pin 7 follows pin 3 in a low level state. Capacitor C7 discharges to pin 7 through D4 through R5 and the lower part of RP2. When the voltage of the terminal capacitor drops between 1/3Vcc and 2/3Vcc, pin 3 keeps outputting (in this language logic, pin 3 outputs low level). When the voltage across C7 drops below 1/3Vcc, pin 3 outputs a high level, and the next cycle begins. And so on and on.

By adjusting the size of R6 and the position of the slider of RP2, the magnitude of the charging current is changed, thereby controlling the charging speed of C7, and achieving the purpose of controlling the proportion of the high level in the square wave. By adjusting the size of R5 and the position of the RP2 slider, the discharge current is changed, thereby controlling the discharge speed of C7, and achieving the purpose of controlling the proportion of low levels in the square wave.

Design the resistance parameters so that the output conforms to the 3-pin output of U4 in the sequential circuit diagram.

When pin 3 outputs a high level, the relay K2 starts to work, the relay switches 3 and 4 are turned on, and the power supply Vcc supplies power to K2 through the photosensitive resistor U3 and R7 to form self-locking. At this time, the pin 3 of U4 has been converted to output a low level , the relay switches 3, 4 and 5, 6 can still maintain the adsorption state. After the relay switches 5 and 6 are connected, the power supply Vcc directly supplies power to the K4 relay through the switch, so the K4 relay has a synchronous working state with the K2 relay, the K4 relay switches 3 and 4 are connected, and the switches 5 and 6 are connected.

K4 relay switch 3,4 is connected, and the power supply of lifting motor 311 passes through the switch 34 of K4, forward power supply to lifting motor 331. The current will first pass through the relay K5, the switches 3 and 4 of K5 are switched on, and the power supply of the automatic control valve 17 supplies power to the automatic control valve 17 through the switches 3 and 4 of K5, so that the automatic control valve is closed. After the current passes through K5, the electric current first passes through R13 to charge the capacitor C13. During the process of charging the capacitor, the lifting motor 331 cannot work, so as to achieve the purpose of delaying the start of the lifting motor 331 and reserve enough time for the automatic control valve to close.

When the lifting motor 331 starts to work, the connecting rod 3321 continues to rise. When the light beam of the first displacement detection device 35 is cut off by the connecting rod 3321, the photoresistor U3 will not be able to receive the light source, and the resistance value will increase, causing the power supply current in the self-locking circuit to decrease. Small, unable to continue to support the work of relay K2, then relays K2, K4 stop working synchronously, all the switches are returned to their original positions, so that the lifting motor 331 stops working, and the purpose of position limitation is achieved.

Referring to Figure 6, the delay module M2 is a model of a delay circuit or timer, which is built by two 555 timers. The control of the delay module M2 needs to be controlled by switches 5, 6, and 7 of the relay K4. When the lifting motor 331 is in the rising process, the switches 5 and 6 of the relay K4 are connected, and the switches 6 and 7 are disconnected. The switches 6 and 7 of the relay K4 are disconnected, causing the module to be in a power-off state, that is, the rotating motor 3331 does not work during the rising process of the lifting motor. After the lifting motor 331 stops working, the relay K4 is powered off, the switches 6 and 7 of K4 are connected, the power supply Vcc of the delay module M2 supplies power to the delay module M2 through the switches 6 and 7 of K4, and 4 of the 555 chips U1 and U2 , 8, 1, and 5 pins are all connected in the same way as the 555 chip of the first timing module M1, and are wired as required. In addition, pins 6, 7, and 2 of the chip of U1 are also the same as those of U4. Pin 3 of U1 charges capacitor C3 through rectifier D1 and resistor R2, and the voltage at both ends of C3 becomes the voltage of pin 6 of U2 through wiring. The basic principle of U1 is the same as that of U4 introduced above. The three pins of U1 can output a square wave signal with adjustable duty cycle. When its pin 3 outputs a high level, it can charge the capacitor C3. The charging and discharging speed of capacitor C6 changes the duty cycle of the square wave signal output by pin 3 of U1, thereby controlling the charging speed of C3. When the switches 6 and 7 of the relay K4 are turned on, the power supply Vcc of the delay module M2 charges C2 through the switches 6 and 7 through R1. Since the voltage at both ends of the capacitor will not change suddenly, the voltage of pin 2 is less than 1/3Vcc at this time, and the capacitor C3 It has just started charging, so the voltage of pin 6 is also less than 2/3Vcc, so pin 3 of U2 outputs high level to supply power to relay K1, and switches 3, 4 and 5, 6 of relay K1 are turned on. After the switches 3 and 4 of K1 are turned on, the power supply Vcc of the delay module M2 supplies power to the capacitor C2 through the switches 3 and 4 through R1 to form self-locking. Therefore, capacitor C2 will continue to charge until the voltage at both ends exceeds 1/3Vcc, and capacitor C3 will be charged intermittently. When the voltage at both ends of C3 is still less than 2/3Vcc, pin 3 of U2 can still maintain a high level output, and relay K1 works to switch When 5 and 6 are connected, the power supply of the rotary motor 3331 can supply power to the rotary motor, and at the same time supply power to the relay K7, the switches 3 and 4 of K7 are connected, and the power supply of the automatic control valve 17 is controlled by the switches 3 and 4 of K7 The valve is powered so that the on-off control valve remains closed. When the voltage across capacitor C3 reaches 2/3Vcc, the potential of pin 6 of U2 reaches 2/3Vcc, and the potential of pin 2 of U2 has exceeded 1/3Vcc, so pin 3 of U2 is at low level, and relay K2 When the power supply is lost, the rotating electrical machine 3331 stops working, thereby realizing the goal of the rotating electrical machine 3331 working at regular intervals.

Referring to FIG. 7 , the second timing module M3 circuit has similar basic functions to the first timing module M1 circuit, and a 555 timer is used to build a timing circuit. The wiring of the 555 chip U7 is exactly the same as that of the first timing module M1, and a 3-pin circuit that can output a square wave signal with an adjustable duty cycle is built. When pin 3 of U7 outputs a high level, power is supplied to relay K3 through D7, switches 3, 4 and 5, 6 of K3 are turned on, switches 3 and 4 are turned on, and the potential feedback circuit composed of photoresistor U6 and R10 will give the relay K3 supplies power to form a self-lock, so that the relay K3 can continue to work. The switches 5 and 6 of K3 are continuously connected, and the power supply of the lifting motor 331 passes through the switches 5 and 6 to supply power for the lifting motor to reverse. At the same time, the relay K6 works, the switches 3 and 4 of K6 are connected, and the power supply of the automatic control valve passes through K6 switches 3 and 4 supply power to the automatic control valve to realize the goal that the automatic control valve is still in the closed state when the lifting motor is working. The lifting motor reverses the connection rod 3321 and descends. When the connection rod 3321 descends to the initial height, the light beam of the second displacement detection device 36 resumes receiving, and the photoresistor U6 receives light again, and the resistance value of the resistance becomes smaller, resulting in a smaller potential at its upper end , unable to provide enough voltage to K3 to maintain its work, so the switches of K3 are all turned off, and the lifting motor 331 stops running.
