Description

Technical Field

[0001] This utility model relates to the field of lifting control system technology, specifically a multi-mode operation control system for an environmental waste treatment station. Background Technology

[0002] As a new generation of environmental protection facilities, underground waste disposal stations are designed by placing garbage bins in underground spaces. A lifting mechanism is used to clean, transport, and lower the bins back underground for continued collection. This method solves the problems of odor, foul smells, and fly and mosquito breeding that plagued traditional above-ground waste stations.

[0003] Most existing underground waste disposal stations rely on motors, drive gears, and chains to achieve overall lifting. However, this method has several problems: the uncontrollable weight of the waste bins leads to the risk of overloading the lifting mechanism. Due to the randomness and fluctuation of waste disposal volume, waste bins often become overfilled or overweight, posing a safety hazard for the motor during prolonged operation under heavy load. When the lifting mechanism lifts an excessively heavy waste bin, it faces the risk of equipment damage. Overloading can easily cause the drive motor to burn out and the chain to break due to overload. A broken chain not only interrupts the lifting operation but may also generate a large impact force at the moment of breakage, causing injury to surrounding equipment and personnel. Gears will also wear out faster or even deform and break, causing frequent equipment failures. Furthermore, under extreme overload conditions, the lifting mechanism may become unstable or jammed due to insufficient strength, affecting the normal operation of the underground waste disposal station. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a multi-mode operation control system for an environmentally friendly waste treatment station, installed within a foundation pit. The foundation pit houses the main body of the underground waste treatment station, which includes a vertically lifting load-bearing platform and a motor-driven lifting mechanism for this purpose. The multi-mode operation control system comprises a drive controller, a motor controller, a hydraulic lifting mechanism, and a weighing sensor. The motor controller is electrically connected to the motor lifting mechanism, and the drive controller is electrically connected to the motor controller, the hydraulic lifting mechanism, and the weighing sensor.

[0005] The drive controller includes a microprocessor, a serial communication module, an analog-to-digital converter, and a power supply module. The serial communication module is electrically connected to the microprocessor via the analog-to-digital converter, and the power supply module is connected to the microprocessor.

[0006] In a specific implementation, the microprocessor model is an STM32F303RBT6 processor.

[0007] The hydraulic lifting mechanism includes several telescopic hydraulic cylinders, several top plates, and solenoid valves. Each telescopic hydraulic cylinder has a top plate fixedly installed at its upper end. The upper surface of the top plate can contact the lower side of the load-bearing platform. The solenoid valves are electrically connected to the drive controller.

[0008] In order to ensure that the hydraulic lifting mechanism maintains balance when lifting the load platform, at least four telescopic hydraulic cylinders are provided, with each telescopic hydraulic cylinder located at one of the top corners of the load platform.

[0009] At least one weighing sensor is installed at the contact point between the load-bearing platform and the base of each trash can.

[0010] The motor lifting mechanism includes a drive motor, a drive gear, and a lifting chain. The drive gear is located on one side of the upper end of the device body and is driven to rotate by the drive motor. The upper end of the lifting chain passes over the upper side of the drive gear and is fixedly connected to the device body, and its lower end is fixedly connected to the load platform. The lifting chain meshes with the upper side of the drive gear.

[0011] The hydraulic lifting mechanism can raise the load-bearing platform to its highest position, level with the ground.

[0012] Beneficial Effects: This utility model is a multi-mode operation control system for an environmentally friendly waste treatment station. A weighing sensor detects the load-bearing weight of the platform in real time, and a motor controller acquires the power data of the motor lifting mechanism. The drive controller compares the power data with the load-bearing weight of the waste using threshold values ​​to accurately determine the light or heavy load state of the platform and switch between light and heavy load lifting control. When the platform is lightly loaded, the motor lifting mechanism lifts it; when the platform is heavily loaded, a hydraulic lifting mechanism assists the motor lifting mechanism in synchronous lifting, providing additional support and sharing the load on the motor lifting mechanism. This not only prevents damage to the motor lifting mechanism due to overload and extends its service life, but also ensures the platform can be lifted smoothly, guaranteeing the normal operation of waste transfer.

[0018] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0019] See Figures 1-2 This embodiment provides a multi-mode operation control system for an environmentally friendly waste treatment station, installed within a foundation pit. The foundation pit houses the main body 1 of the underground waste treatment station. The main body 1 includes a vertically lifting load-bearing platform 2 and a motor-driven lifting mechanism for moving the load-bearing platform 2. Furthermore, to enable switching between light and heavy loads on the load-bearing platform 2 according to different load capacities, the multi-mode operation control system includes a drive controller, a motor controller, a hydraulic lifting mechanism, and a weighing sensor.

[0020] The motor controller is electrically connected to the motor lifting mechanism. The motor controller drives the motor 3 lifting mechanism to operate and detects and acquires the power data of the motor lifting mechanism. The drive controller is electrically connected to the motor controller, the hydraulic lifting mechanism, and the weighing sensor. The weighing sensor can detect the load-bearing weight of the load platform 2 in real time and transmit the detection signal to the drive controller in real time. The drive controller can receive the power data detected by the motor controller and the detection signal from the weighing sensor, and thus control the hydraulic lifting mechanism to operate according to the data signals.

[0021] In order to lift the load platform 2, the motor lifting mechanism includes a drive motor 3, a drive gear 4 and a lifting chain 5. The drive gear 4 is located on one side of the upper end of the device body 1 and is driven to rotate by the drive motor 3. The upper end of the lifting chain 5 passes over the upper side of the drive gear 4 and is fixedly connected to the device body 1, and its lower end is fixedly connected to the load platform 2. The lifting chain 5 meshes with the upper side of the drive gear 4.

[0022] Subsequently, when the load-bearing platform 2 is overloaded, in order to provide additional support to share the load of the motor lifting mechanism, the hydraulic lifting mechanism is fixedly installed at the bottom of the pit, capable of lifting the load-bearing platform 2 to its highest position flush with the ground. The hydraulic lifting mechanism includes several telescopic hydraulic cylinders 6, several top plates 7, and solenoid valves. Each telescopic hydraulic cylinder 6 has a top plate 7 fixedly installed at its upper end, and the upper surface of the top plate 7 contacts the lower side of the load-bearing platform 2. The solenoid valves are electrically connected to the drive controller and are used to receive control signals from the drive controller to supply hydraulic oil to the telescopic hydraulic cylinders 6. Furthermore, to ensure the balance of the load-bearing platform 2 during the lifting process, at least four telescopic hydraulic cylinders 6 are provided, each located at one of the top corners of the load-bearing platform 2.

[0023] In order to detect the total garbage load capacity of the load-bearing platform 2, at least one weighing sensor is provided at the contact connection position between the load-bearing platform 2 and the base of each garbage bin, for directly measuring the weight applied to the load-bearing platform 2 by the garbage bin.

[0024] When the underground waste treatment station transfers and processes the collected waste, environmental personnel activate the lifting mechanism of the underground waste treatment station from above ground. The motor controller drives the lifting mechanism of motor 3 to lift the load platform 2. The motor controller detects the drive voltage and drive current data in real time to obtain power data, and transmits the acquired drive data of the motor lifting mechanism to the drive controller. At the same time, the weighing sensor also transmits the measured total weight data of the waste to the drive controller.

[0025] To enable the drive controller to distinguish between the light and heavy load states of the load platform 2, the drive controller includes a microprocessor, a serial communication module, an analog-to-digital converter (ADC), and a power supply module. The serial communication module is electrically connected to the microprocessor via the ADC, and the power supply module is connected to the microprocessor to supply power to the entire drive controller. The input terminal of the serial communication module is externally connected to a motor controller and a weighing sensor to receive data signals transmitted from these two devices. The ADC converts the received electrical signals into digital signals and transmits them to the microprocessor. In this embodiment, the microprocessor is an STM32F303RBT6 processor, which stores preset power thresholds and preset heavy load thresholds. The microprocessor can compare the acquired power data and total waste weight data with the corresponding preset thresholds to determine whether the load platform 2 is in a heavy load state.

[0026] When both the power data and the total weight of the garbage are below the preset threshold, the load platform 2 is in a light-load state. At this time, the drive controller does not drive the hydraulic lifting mechanism, and only the motor lifting mechanism lifts the load platform 2. When the load platform 2 is in a heavy-load state, the motor lifting mechanism may not be able to support the lifting of the load platform 2. The drive controller drives the telescopic hydraulic cylinder 6 to work by controlling the solenoid valve. The hydraulic lifting mechanism assists the motor lifting mechanism in lifting the load platform 2 synchronously. The lifting speed of the motor lifting mechanism and the hydraulic lifting mechanism are consistent until the load platform 2 is level with the ground, so that environmental protection personnel can clean the garbage cans placed on the load platform 2.
