Description

Technical Field

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 A schematic diagram of the distribution of the system of the present invention; Figure 2 It is a schematic diagram of module connection of the present invention. DETAILED DESCRIPTION

[0015] Reference Figure 1 to Figure 2 The embodiments of the present invention are further described.

[0016] This embodiment specifically includes: a pipeline for sewage transportation, and a negative pressure collection well for sewage treatment connected by the pipeline, a plurality of relay stations and a smart negative pressure station, and these relay stations are linked by an intelligent control module.

[0017] The relay station is equipped with a vacuum pump, a compressor, a regulating air pipe, a regulating valve, a liquid vibration energy recovery device, and an energy storage module.

[0018] The input end of the vacuum pump is connected to the negative pressure pipeline of the relay station, which is used to extract air from the pipeline to form a negative pressure environment. The output end of the vacuum pump is connected to the negative pressure chamber of the relay station through a flow control valve to ensure that negative pressure is formed and stably maintained inside the relay station, thereby maintaining an effective connection with the external negative pressure pipeline.

[0019] The compressor serves as a backup negative pressure generating device in the relay station. Its output end is connected to the negative pressure chamber of the relay station through a pipe, and the input end of the compressor is connected to the compressed air storage tank. When the system negative pressure is insufficient, the compressed air in the tank can be quickly replenished to the negative pressure chamber through the compressor. The compressor is also connected to the intelligent control module to realize remote control and intelligent adjustment to ensure the smooth operation of the system when the load changes.

[0020] The liquid vibration energy recovery device includes a vibration capture device, a piezoelectric material and a rectifier circuit. The vibration catcher fits tightly to the outer wall of the water inlet or outlet pipe. The tiny vibrations generated by the sewage flowing in the pipe are transmitted to the piezoelectric material through the vibration catcher, and the piezoelectric material can convert these vibration energies into electrical energy. In order to achieve efficient energy conversion, the piezoelectric material is connected to the rectifier circuit to convert the generated alternating current into stable direct current. The rectified electrical energy is transmitted to the energy storage module through cables to ensure that the energy is effectively stored and used for subsequent system operations.

[0021] The energy storage module is responsible for storing the electrical energy generated by the liquid vibration energy recovery device and powering the low-power devices in the relay station. The energy storage module consists of three main parts: energy storage unit, power control unit and distributed power management unit.

[0022] The power control unit is electrically connected to the energy storage unit, and can monitor the charging and discharging status of the energy storage unit in real time, and automatically adjust the output rate of electric energy according to the current power demand of the system, ensuring that the system can maintain stable operation when the load fluctuates. The power control unit also has an intelligent energy prediction module, which can predict future power demand through historical data and current system status, and adjust the charging strategy of the energy storage unit in advance to avoid energy shortage under high load.

[0023] The distributed power management unit is used to share power among multiple relay stations. When the energy storage unit of a relay station is low on power, the distributed power management unit can dynamically dispatch the power resources of other relay stations to ensure the overall balanced operation of the system.

[0024] The regulating air pipe and the regulating valve, the regulating air pipe connects the negative pressure chambers of each relay station together, so as to realize the negative pressure sharing across the relay stations. One end of the regulating air pipe is connected to the negative pressure chamber of the relay station, and the other end is connected to the negative pressure chamber of the adjacent relay station. The valve is installed on the regulating air pipe and is electrically connected to the intelligent control module. The intelligent control module automatically adjusts the opening or closing state of the valve according to the negative pressure requirements of each relay station to ensure the reasonable distribution and coordinated work of the negative pressure between the relay stations, and avoid the negative pressure of a certain relay station being too high or too low.

[0025] The intelligent control module plays a core control role in the operation of the entire system. The intelligent control module includes a central processing unit, a sensor interface, a power management unit, an equipment control interface and communication unit, and an emergency negative pressure recovery unit.

[0026] The intelligent control module is connected to the central control server through a data bus. The server remotely monitors the operating status of the system through a communication unit and sends control instructions as needed to realize remote management functions.

[0027] The central processing unit is connected to the sensor module in the relay station through the sensor interface to collect data such as negative pressure, flow rate, liquid level and power status in the relay station in real time.

[0028] The equipment control interface is electrically connected to the vacuum pump, compressed air device and regulating valve, and receives the control signal from the central processing unit; The central processing unit automatically adjusts the working status of the vacuum pump, compressor and regulating valve according to these data to ensure that the system is in the best operating state.

[0029] The power management unit distributes the power stored in the storage module to low-power devices (sensors, etc.) based on the power requirements of the relay station, ensuring that these devices can still work normally when the external power is interrupted.

[0030] The emergency negative pressure recovery unit includes an abnormality detection module, a backup negative pressure generating device, an energy management module, a fault self-repair module, and a negative pressure sharing module.

[0031] The abnormality detection module is electrically connected to the sensor interface, receives data from each sensor through the sensor interface, and feeds back the fault information to the central processing unit of the intelligent control module; The standby negative pressure generating device is electrically connected to the device control interface, and the central processing unit issues a start-up command and adjusts the operating state of the device.

[0032] The energy management module is connected to the power management unit and the energy storage module, and dynamically allocates the use of electric energy in emergency situations according to the instructions of the central processing unit.

[0033] The fault self-repair module is connected to the sensor interface and the equipment control interface, and adjusts the equipment operation state according to the fault condition through the central processing unit.

[0034] The negative pressure sharing module exchanges data and schedules resource sharing with the intelligent control modules of adjacent relay stations through the communication unit, and coordinates the negative pressure generation and power distribution of multiple relay stations.

[0035] The intelligent control module monitors the negative pressure, liquid level, flow rate and power status of the relay station through the abnormal detection module. When insufficient negative pressure, vacuum pump failure or power outage is detected, the backup negative pressure generating device in the emergency recovery mechanism is immediately triggered, and the backup vacuum pump is automatically started to maintain the negative pressure level of the system.

[0036] In emergency mode, the energy management module will prioritize allocating electricity from the energy storage module to key equipment, ensuring the continuous operation of the system during emergencies. In addition, the negative pressure sharing module can adjust the negative pressure between relay stations to ensure a smooth transition of the entire system in emergency situations.

Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
