Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0047] Figure 1 This is a schematic diagram of the principle of this utility model. Detailed Implementation

[0048] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0049] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0050] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0051] Traditional bar screen drive systems typically separate the measuring device, control device, and drive device, resulting in complex equipment. Furthermore, traditional bar screen drive systems adjust the bar screen's operating mode by detecting pollution levels within the bar screen channel, leading to a single control method. Additionally, each device suffers from issues such as interface incompatibility and low heat dissipation efficiency.

[0052] To address the aforementioned problems, this utility model proposes an integrated measurement, control, and drive device for a bar screen machine, which integrates a measuring device, a control device, and a drive device into one unit, serving as a measuring module, a control module, and a drive module, respectively.

[0053] The measurement module has at least one interface module, which can be connected to a liquid level difference sensor.

[0054] The control module has an intelligent controller that serves as the processing core, and the control module can at least perform human-machine interaction, protocol communication, and data storage;

[0055] The drive module has a servo drive module or vector frequency conversion drive module as the power core, and a load detection submodule for real-time acquisition of the bar screen machine's operating current.

[0056] When the bar screen is running, the control module can generate control commands based on the liquid level difference data collected by the liquid level difference sensor, the operating current collected by the load detection submodule, and the bar screen speed. The drive module adjusts the output according to the control commands to change the bar screen speed.

[0057] As can be seen from the above settings, this utility model has a measurement module, a control module, and a drive module, realizing an integrated measurement, control, and drive system. In addition, the control method of this utility model for the bar screen is mainly based on the operating current of the bar screen, eliminating the need for additional traditional onboard current or voltage sensors, torque sensors, etc., thus reducing costs and installation complexity. Furthermore, the above control method achieves closed-loop regulation of "load-speed-operating status" by collecting the operating current in real time and dynamically analyzing load changes, thereby improving the bar screen cleaning efficiency and reducing motor energy consumption.

[0058] The following describes the configuration of each module in this utility model:

[0059] The measurement module, as the sensing layer of this utility model, simplifies the sensor configuration in traditional solutions and, combined with the current detection technology of the drive module, achieves dual sensing of "basic data acquisition + monitoring without additional sensor load".

[0060] It retains a liquid level difference sensor (and can also be set with multiple sensors as needed) to detect the liquid level difference before and after the bar to help determine the clogging trend. It eliminates the traditional torque sensor and indirectly obtains the load torque through the current loop detection technology of the drive module.

[0061] The measurement module contains independently packaged sensor sub-modules that can be allocated as needed (only the liquid level difference sensor is retained under simple working conditions). The interface adopts the RS485 (Modbus RTU) protocol. When replacing, only matching according to module parameters is required, which improves maintenance efficiency by more than 60%.

[0062] The control module, as the decision-making layer of this utility model, adopts an intelligent controller as its core and integrates human-computer interaction and multi-protocol communication functions, serving as the "decision center" of this utility model.

[0063] It has a core chip (i.e., intelligent controller), a human-computer interaction submodule, a communication submodule, and a data storage submodule;

[0064] The core chip uses an industrial-grade high-performance A7 processor, which supports multi-task parallel processing and load algorithm calculation.

[0065] The human-machine interaction sub-module is equipped with a 7-10 inch color LCD touch screen and corresponding physical emergency buttons. It supports viewing operating data (speed, operating current, liquid level difference, load rate, etc.), setting thresholds (overload current, upper limit of liquid level difference, etc.), and manually controlling start and stop functions.

[0066] The communication submodule integrates at least one of the following: LAN module, WIFI module, and 4G module. It supports TCP or IP protocol and is used to connect to a host computer or water management platform.

[0067] The data storage submodule has a built-in EEPROM (programmable data memory) and a 64GB SD card, which can store more than one year of operating data and fault records;

[0068] The control module adopts a "core board + expansion board" architecture. The expansion board can be stacked with an AI algorithm module to realize the prediction of screenings blockage. The communication module supports "LAN / WiFi / 4G" switching as needed without replacing the entire control module, and is adapted to different field network environments.

[0069] The drive module, as the execution layer of this utility model, adopts a servo drive module or a vector frequency conversion drive module as the power core to achieve "precise drive + load detection without additional sensors", replacing the traditional combination of drive and independent torque sensor.

[0070] It features a driver core, a load detection submodule, a protection submodule, and a standard interface;

[0071] The servo drive module or vector frequency conversion drive module serves as the power core and is used to select the specific drive module according to the power of the bar screen (selected before leaving the factory; for example, if the bar screen motor is a servo motor, a servo drive module is selected; if the bar screen motor is an asynchronous motor, a vector frequency conversion drive module is selected).

[0072] The load detection submodule has a built-in current loop detection circuit. It collects the operating current of the motor in the bar screen in real time and converts it into load torque by combining motor parameters (rated current, power factor, etc.) (detection error ≤ ±3%), without the need to install an additional torque sensor.

[0073] The protection submodule integrates overload protection (triggered when current exceeds 120% of rated current), phase loss protection, overvoltage protection (triggered when voltage exceeds 380V±15%), and overtemperature protection (triggered when drive module temperature exceeds 75℃).

[0074] The standardized interface uses a terminal-type interface for connection to the motor in the bar screen machine.

[0075] The starting module is divided into sub-models according to power. When replacing it, only the motor power needs to be matched. The load detection and drive are integrated into one unit, reducing wiring and fault points, and shortening the average fault repair time to less than 25 minutes.

[0076] Furthermore, based on the aforementioned measurement module, control module, and drive module, this utility model also adds an auxiliary function module to realize functions such as heat dissipation, power supply, and installation protection. To realize these functions, the auxiliary function module is divided into a power supply module for power supply, a heat dissipation module for heat dissipation, and a housing and installation module for protection and assembly.

[0077] The power module is independently packaged and supports wide voltage input (AC220V±10% / AC380V±10%, supporting 220V and 380V AC voltage input, with 10% being the input deviation range). The output terminal uses standardized terminals and has built-in surge protection circuit (resistant to 2kV lightning strikes) and filter circuit to adapt to different field power supply conditions.

[0078] The heat dissipation module has a fan heat dissipation hole on the side of the outer shell of this utility model, and an internal "U-shaped professional air duct" (forming a directional airflow from the air inlet → control module → drive module → air outlet). It is equipped with a 24V silent axial fan (air volume 15CFM, speed 2000rpm). An aluminum heat sink is added to the bottom of the drive module to ensure that the internal core module temperature does not exceed 65℃ in an environment of -10℃ to 50℃, and the heat dissipation efficiency is improved by 40%.

[0079] The enclosure and mounting modules have an IP54 protection rating and adopt a compartmentalized structure (control compartment, drive compartment, and power compartment are independently separated) to avoid heat conduction between modules. The installation methods support wall mounting, floor mounting, and flange mounting. The bracket is detachable to adapt to different site spaces.

[0080] Please see Figure 1 The aforementioned measurement module, control module, drive module, and auxiliary function module constitute the modular design of this utility model. Through the above-mentioned configuration, the beneficial effects described above can be achieved:

[0081] This invention employs a dynamic speed adjustment method to ensure that the bar screen maintains optimal cleaning efficiency regardless of changes in the amount of screenings. Compared to fixed speed control, the screenings cleaning efficiency is increased by 25%. When the bar screen is under light load, it operates at low speed, which reduces motor energy consumption by 18%-22% compared to traditional 24-hour full-load operation. When the bar screen is overloaded, relevant protection is provided to avoid mechanical impact caused by overload, extending the service life of vulnerable parts such as the bar screen chain and bearings by 30%. Furthermore, control is achieved through current acquisition, eliminating the need for additional torque sensors, reducing hardware costs, and minimizing sensor maintenance workload.

[0082] As can be seen from the above module settings, this utility model has multiple interfaces, specifically including a LAN interface, a USB interface, an RS485 interface, a power supply interface, a grille motor interface, and a WIFI / 4G interface.

[0083] The LAN interface is used to connect to the host computer or water platform to transmit liquid level difference data collected by the liquid level difference sensor, operating current collected by the load detection submodule, speed of the bar screen, and control commands generated by the control module.

[0084] The USB interface is used to export historical data and to upgrade firmware;

[0085] The RS485 interface is used to connect various external sensors, including liquid level difference sensors, as well as third-party devices;

[0086] The power supply interface is used to connect to a power supply that supports a wide voltage input.

[0087] The bar screen motor interface is used to connect the motor in the bar screen to transmit driving power to the motor in the bar screen.

[0088] The WIFI / 4G interface is used to enable wireless communication.

[0089] Specifically, the LAN interface uses an RJ45 interface adapted to 10Mbps or 100Mbps data transmission; the USB interface uses a USB 2.0 Type-A interface; the RS485 interface uses a terminal interface supporting the Modbus RTU protocol; the power supply interface uses a terminal interface supporting a voltage input of 220V or 380V; the grid machine motor interface uses a terminal interface for connecting to a motor with an operating voltage of 220V or 380V; and the WIFI / 4G interface is a combination of a built-in antenna and an SMA interface.

[0090] In terms of interface design, the LAN interface is marked in blue and equipped with a dust cover; the USB interface is marked in black and only supports data reading; the RS485 interface terminals are marked "RS485-A / B" and are equipped with reverse connection protection circuit; the power supply interface terminals are marked "L / N / PE" and are equipped with an insulating protective cover; the grille motor interface terminals are marked "U / V / W"; and the SMA interface is equipped with a waterproof plug.

[0091] All external interfaces are integrated into the "interface panel" of the outer shell of this utility model, supporting plug-and-play functionality and anti-misplugging design, as detailed below:

[0092]

[0093] Among the above schemes, the one that calculates the load rate based on the current and executes corresponding control is:

[0094] The drive module collects the operating current of the motor in the bar screen in real time (sampling frequency above 10Hz), and the control module combines the rated current of the motor (e.g., the rated current of a 1.5kW motor is 3A) to calculate the load rate (operating current / rated current × 100%).

[0095] If the load rate is ≤50%, it is judged as "light load" (low amount of screenings) and low speed operation is maintained (e.g., 10 rpm).

[0096] If 50% < load rate ≤ 80%, it is judged as "normal load" (moderate amount of slag), and the rated speed (e.g., 15 rpm) should be maintained.

[0097] If 80% < load rate ≤ 110%, it is judged as "heavy load" (sandblasting accumulation trend), and the rotation speed is automatically increased (e.g., 20 rpm) to enhance the sandblasting cleaning ability;

[0098] If the load rate is greater than 110%, it is judged as "overload" (severe blockage by slag or mechanical obstruction), triggering the protection mechanism.

[0099] When under light / normal load, the motor in the bar screen maintains the current speed through the drive module, while detecting the liquid level difference. If the liquid level difference exceeds 30mm (customizable), the speed is increased by 5rpm to prevent the accumulation of bar screen residue.

[0100] When under heavy load, the drive module controls the motor to continuously increase the speed to 25rpm (upper limit). If the load rate does not decrease within 10 minutes, an audible and visual alarm is triggered (local LCD screen flashes + buzzer alarm), and the alarm information is uploaded to the operation and maintenance platform via 4G / LAN.

[0101] When overloaded, a "stop" command is immediately sent to the drive module to cut off the motor power supply. At the same time, fault data (fault time, current value, load rate) is recorded and pushed to the cloud platform.

[0102] Based on the above settings, this utility model has the following beneficial effects:

[0103] 1. Improved efficiency: Dynamic speed adjustment ensures that the bar screen maintains optimal cleaning efficiency regardless of changes in the amount of screenings. Compared to fixed speed control, the screenings cleaning efficiency is improved by 25%.

[0104] 2. Reduced energy consumption: When operating at low speed under light load, the motor energy consumption is reduced by 18%-22% compared to traditional 24-hour full-load operation;

[0105] 3. Reduced wear: Avoids mechanical impact caused by overload, extending the service life of vulnerable parts such as the bar screen chain and bearings by 30%;

[0106] 4. Cost savings: No additional torque sensor is required, reducing hardware costs and sensor maintenance workload.

[0107] The application of this utility model will be described below with reference to specific embodiments:

[0108] It includes a startup phase, during which the following is executed:

[0109] 1. Connect the power supply on site. The power module supplies power to the control module and drive module. The control module is initialized (reading historical parameters and detecting communication status).

[0110] 2. Maintenance personnel set parameters (rated speed 15 rpm, overload current 3.3A, upper limit of liquid level difference 30mm) through the human-machine interface and click the "start" command;

[0111] 3. The drive module starts the bar screen motor and simultaneously begins to collect the operating current.

[0112] It also includes a runtime phase, under which the following actions are performed:

[0113] 1. The measurement module transmits the liquid level difference (e.g., 20mm) and rotation speed (10rpm) to the control module in real time, and the drive module transmits the current value (1.8A, 60% load rate).

[0114] 2. The control module determines "normal load + normal liquid level difference" and maintains a rotation speed of 10 rpm;

[0115] 3. After 30 minutes, the liquid level difference rises to 35mm, the current value rises to 2.4A (load rate 80%), the control module sends a "speed increase to 15rpm" command, the drive module adjusts the output frequency, the motor speed increases, and the current value drops to 2.1A (load rate 70%).

[0116] And includes a fault handling phase, under which the following actions are performed:

[0117] 1. When a foreign object gets stuck in the bar screen, the current value suddenly rises to 3.5A (load rate 117%, overload), and the drive module immediately sends out an "overload signal".

[0118] 2. The control module sends a "stop" command to cut off the motor power supply, the human-machine interface displays "overload fault", and the buzzer sounds an alarm;

[0119] 3. At the same time, the fault information is pushed to the maintenance personnel's APP via 4G. After the maintenance personnel arrive at the site, they remove the foreign objects and click the "Reset" button to restore the device to operation.

[0120] In summary, this utility model has the following technical advantages:

[0121] 1. Strong compatibility: Modular design + multiple standard interfaces (LAN / USB / RS485 / WiFi / 4G) to adapt to different specifications of bar screens and field environments, without the need for customized development;

[0122] 2. Intelligent and efficient: Current loop detection technology + dynamic load regulation breaks through the limitations of traditional control and realizes intelligent management of the entire process of "load-speed-fault";

[0123] 3. Convenient maintenance: Independent module packaging + precise fault location + remote early warning, maintenance time is reduced by 60%, and the frequency of on-site inspections by maintenance personnel is reduced from twice a day to once a week;

[0124] 4. Reliable heat dissipation: Professional air duct + fan cooling holes + compartmentalized structure ensure stable operation in environments ranging from -10℃ to 50℃, reducing the failure rate of core modules by 40%;

[0125] 5. Controllable cost: No additional sensor design + reduced energy consumption + extended lifespan, reducing the total lifespan cost of a single device by 25%-30%.

[0126] It can be adapted to the following application scenarios:

[0127] 1. Inlet bar screen for urban wastewater treatment plants: compatible with rotary bar screen (1.5kW), and connected to the smart water management platform via 4G to achieve unmanned operation;

[0128] 2. Industrial Park Wastewater Treatment Station: For high-viscosity wastewater (such as chemical wastewater), current loop detection technology is used to accurately identify screenings blockage and avoid motor overload;

[0129] 3. Pumping stations in remote areas: The combination of "solar power supply + WiFi / 4G communication" is adopted to solve the problems of no mains power and no wired network, thereby reducing operation and maintenance costs.

[0130] This utility model also proposes a bar screen machine, which has the integrated measurement, control and drive device for the bar screen machine described above.

[0131] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
