detailed description

The sewage lifting system is provided with a sewage container for storing sewage. The sewage container is connected with a sewage pump pipe and a sewage inlet pipe. The sewage pump pipe is connected with a sewage pump. The sewage in the sewage container can be discharged regularly through the sewage pipe and the sewage pump.

This application utilizes the sensor to directly control the work of the sewage pump to avoid the overflow of sewage. At the same time, in order to ensure the accuracy of detection, there are three water level sensors, which are air pressure sensor 9, photoelectric water level sensor and float level sensor. In contact with sewage, its stability is higher and its service life is longer.

The container cover is provided with a hose 11 communicating with the hollow columnar structure, and the end of the hose 11 is provided with an air pressure sensor 9, which outputs a liquid level signal to the controller. If the sewage water level exceeds the hollow columnar structure, the hose 11 will The air pressure will increase, and the pressure increase signal will be received by the air pressure sensor 9, and the water level condition can be accurately obtained by analyzing the pressure through the controller.

In addition, a photoelectric water level sensor and a float level sensor are installed in the sewage container. The photoelectric water level sensor and the float level sensor output sensing signals to the controller, and the controller outputs control signals to the sewage pump to realize automatic control. The purpose of the sewage pump to adjust the sewage water level.

The components outside the sewage container are all solidified in the casing 1, as shown in Figures 1 and 2, the casing 1 is provided with a display and control panel 17, a buzzer 10, and the control outputs an alarm signal to the buzzer 10 , Display and control panel 17. The controller is connected with a communication unit, and the communication unit sends a water level signal to the terminal server or the mobile terminal. The mobile terminal can be a mobile phone or a dedicated PDA.

Two integrated circuit boards 2 (controllers) are installed in the box body 1, and the required electronic components are welded on each circuit board 2 to form a connected circuit. The two circuit boards are connected by a flexible cable 14, and the buzzer When the device 10 is installed on the casing 1 and the alarm sounds. Sewage lift pump control box adopts 220V single-phase power supply, with 9V rechargeable battery 15 for alarm when power is off, and has 3 analog inputs, 1 pressure switch detection, 1 current detection, and 1 voltage detection; 12 1 digital input, 1 fuse 7 detection, 3 digital inputs, 3 pass detection of float switch, 7 key inputs, 1 photoelectric switch input; 2 digital outputs, used to control relay 8, One of the relays 8 is used for transfer to control the high-current relay 8, and one relay 8 is reserved for dry contact alarm output. The connection terminal 12 is connected to the outside through the connection hole 13 to transmit data signals. The sewage flows in one direction through the check valve to avoid the reverse flow of the drainage. The sewage pump control box adopts multiple monitoring modes (continuous pressure sensor, photoelectric sensor and float level sensor) to prevent system failures caused by system monitoring errors or sensor failures in a single working mode.

As shown in the figure, the single chip microcomputer 6, transformer 3, current transformer 4, voltage transformer, fuse 7, relay 8, air pressure sensor 9, buzzer 10, terminal 12 and other electronic devices are connected to each other through the wires on the circuit board 2 , to form a connected circuit, the two circuit boards 2 are directly connected through the flexible cable 14, the terminal 12 is connected to the outside through the wiring hole 13, the 9V rechargeable battery 15 is used for alarming when the power is off, and the air pressure sensor 9 is connected to the outside through the hose 11 connected externally.

Press the key to silence the alarm, and the mode change key can be used to change the mode.

In addition, a contact switch is provided between the container cover and the sewage container to determine whether the container cover is open, to ensure the accuracy and stability of the signal of the air pressure sensor 9, and the contact switch outputs a control signal to the controller. If the contact switch is disconnected, the signal acquisition of the air pressure sensor 9 is closed.

In order to prevent the sediment in the sewage tank from affecting the working efficiency of the sewage pump, and to avoid the accumulation of more and more sediment over time, which will affect the capacity of the sewage container, the sewage container is equipped with a stirring mechanism, and the inner wall of the bottom of the sewage container is set at a height (set according to needs) There are slides on both sides, the height of the slides on both sides is the same, there is a push rod between the slides, the push rod is driven by a hydraulic cylinder or air cylinder to move along the slide, and a pressure sensor is installed between the hydraulic cylinder or air cylinder and the push rod. The pressure sensor senses whether there is deposition at the height, the pressure sensor outputs a sensing signal to the controller, and the controller outputs a control signal to the stirring mechanism, and if there is deposition, it will be disturbed by the stirring mechanism.

The control method based on the above sewage lifting system is as follows:

Step 1. Power on the system to start;

Step 2, the air pressure sensor 9, the photoelectric water level sensor and the float level sensor adopt the water level signal in real time; after each collection, it can be displayed on the display screen 18 in real time, and the signal is sent to the terminal through the communication unit at regular intervals;

Step 3. If one or both of the sensors collect abnormal water level signals, start the sewage pump and send out abnormal sensor alarm signals at the same time to remind the user that there is an abnormal sensor. After the water level, turn off the sewage pump; if all sensors collect abnormal water level signals, start the sewage pump, and turn off the sewage pump when the sensor collects the water level again and drops to the preset safe water level.

In step 3, if the abnormal water level signal is collected, the system starts the hydraulic cylinder or cylinder once, and pushes and pulls the push rod back and forth once. If the value of the pressure sensor is greater than the preset threshold, the stirring mechanism is started for the preset time, and after the stirring is completed Start the sewage pump, if the value of the pressure sensor is not greater than the preset threshold, then start the sewage pump directly, so as to ensure that the deposition in the sewage container is within a reasonable range every time the sewage is discharged.
