Description

Technical Field

[0001] The present technical solution relates to the technical field of algae removal devices, and specifically to a variable frequency ultrasonic algae removal device. Background Art

[0002] As the domestic drinking water supply becomes increasingly tight, the country has stepped up efforts to protect the ecological environment of drinking water sources, significantly improving the ecological environment. However, algae, as part of the water source ecology, have repeatedly caused algal blooms across the country, causing serious deterioration in water quality and directly threatening residents' drinking water safety. To prevent similar incidents, some drinking water sources have adopted algae removal methods by injecting chemical agents into the water source. However, while this method kills algae, it also pollutes the water itself and disrupts the ecological balance of underwater flora and fauna, effectively creating another form of pollution while removing algae. Ultrasonic pulse algae removal is an advanced algae removal and control method that has emerged in the past decade. It uses electromagnetic fields to destroy algae cell walls and membranes, effectively reducing the number of algae cells without disrupting the overall balance of the water source ecology, and has an excellent algae removal and control effect on protecting water sources. However, existing ultrasonic algae removal devices float on the water surface, making them inconvenient to maintain and repair. Utility Model Content

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0021] refer to Figure 1 、 Figure 2 and Figure 3 . Figure 1 This is a schematic diagram of the overall structure of the variable frequency ultrasonic pulse algae removal device. Figure 2 This is a schematic diagram of the connection structure between the photovoltaic power generation device and the water quality detection module.

[0022] Algal blooms are characterized by widespread turbidity and discoloration in water caused by the presence of large amounts of algae or cyanobacteria. They are a key indicator of eutrophication. Human wastewater, which contains high levels of plant nutrients (nitrogen and phosphorus), contributes to eutrophication, providing abundant nutrients for algae and promoting their proliferation.

[0023] Ultrasonic pulse algae removal is an advanced algae removal and control method that has emerged in the past decade. It uses electromagnetic fields to destroy the cell walls and cell membranes of algae, which can effectively reduce the number of algae cells without disrupting the overall balance of the water source ecology. It has a good algae removal and control effect on protecting water sources.

[0024] However, algae cells have a certain adaptability and immunity to fixed-frequency ultrasonic pulses. In view of this characteristic of algae cells, the utility model provides a variable-frequency ultrasonic algae removal device, including: a water quality detection module, a first wireless communication module, a data receiving module and an ultrasonic pulse module.

[0025] In order to detect the algae content in the water, in some further specific examples, the water quality detection module includes a water quality detection sensor array and a buoy. The water quality detection sensor array is installed under the buoy, and the water quality detection sensor array is used to detect water quality and output water quality data. A water quality detection sensor is a device that can detect specific chemical substances or physical parameters in water. It converts the chemical components in the water into electrical signals, which are then read and analyzed by the instrument, thereby achieving real-time monitoring of water quality. A water quality detection sensor array is usually composed of multiple different types of water quality sensors. These sensors may include temperature sensors, pH sensors, dissolved oxygen sensors, turbidity sensors, conductivity sensors, etc. These sensors are integrated into an array and can monitor multiple parameters in the water body, such as temperature, pH, dissolved oxygen content, turbidity, conductivity, etc., simultaneously or separately.

[0026] To transmit water quality data to the data receiving module, in some further specific embodiments, data transmission is performed via a first wireless communication module and a second wireless communication module. The first wireless communication module is installed above the buoy, and the second wireless communication module is installed within the data receiving module. Both the first and second wireless communication modules utilize the ZigBee protocol, also known as ZigBee, a low-speed, short-range wireless protocol. The ZigBee protocol consists of two parts: the physical layer and the media access layer. The network layer, application layer, and application support sublayer have unified definitions and specifications. The ZigBee protocol stack integrates the physical layer, media layer, and network layer, implementing them as functions and providing users with an API that allows them to directly call them during wireless transmission. The protocol stack is the specific implementation of the protocol and can be understood as code or a function library for upper-layer applications to call. The basic principle of wireless transmission and reception is: calling the protocol stack's networking and joining functions to establish communication between network nodes. The sending node calls the protocol stack's wireless data sending function to transmit wireless data, and the receiving node calls the protocol stack's wireless data receiving function to receive wireless data. ZigBee technology utilizes a low-power design concept, enabling long-term operation in small devices without frequent battery replacements. It features a short duty cycle, low power consumption for transmitting and receiving information, and a sleep mode for the Reduced Function Device (RFD) that allows it to enter sleep mode when not in use.

[0027] To power the water quality testing module, some further specific examples employ photovoltaic power generation devices and batteries. The photovoltaic power generation device generates electricity, while the battery stores the electricity generated by the photovoltaic power generation device and powers the water quality testing module. The basic principle of photovoltaic power generation is the photovoltaic effect: when photons strike a metal or semiconductor material, their energy is completely absorbed by an electron within the material. When the absorbed energy is sufficiently high, the electron overcomes the material's internal gravitational pull, performs work, and escapes from the surface as a photoelectron. This process first involves the conversion of photons (light waves) into electrons, and then the conversion of light energy into electrical energy. Secondly, a voltage is generated. With this voltage, if the positive and negative electrodes are connected, a current circuit is formed, generating electrical energy. A lead-acid battery uses dilute sulfuric acid as its electrolyte, with lead dioxide as the positive electrode and lead flake as the negative electrode.

[0028] To analyze water quality information and control the ultrasonic pulse module, in some further specific examples, the data receiving module utilizes an ATmega328P processor. After receiving water quality data, the data is classified into different levels. When the comprehensive indicator value exceeds the set level, the ATmega328P processor controls the ultrasonic transmitter to output pulse waveforms of different frequency levels. The greater the excess value, the higher the transmitted pulse frequency. PWM pulse frequency control output is achieved through calculation and comparison. PWM (Pulse Width Modulation) is an analog control method that modulates the bias of the transistor base or MOS transistor gate according to the corresponding load changes, thereby controlling the transistor or MOS transistor's on-time and thus achieving the purpose of adjusting the load power. This is achieved by varying the pulse width, or duty cycle, of the pulse train to equivalently obtain the desired waveform (including shape and amplitude). The ATmega328P is a microcontroller in the 328 series. The processor uses an 8-bit AVR core. The ATmega328P has 32KB of flash memory and 2KB of SRAM (Static Random-Access Memory), which are used to store permanent data and time data respectively. It has 23 digital input and output pins, 3 timers, 6 PWM output channels, and serial communication ports including 1 USART (Universal Synchronous / Asynchronous Receiver / Transmitter), 1 SPI (Serial Peripheral Interface), and 1 I2C (Inter-Integrated Circuit) interface, giving the chip the ability to operate in multiple channels. Due to the use of RISC architecture and an efficient instruction set, the ATmega328P can provide higher performance at a lower operating frequency. The ATmega328P has three timers: Timer 0, Timer 1, and Timer 2. Timer 0 and Timer 2 are 8-bit timers, while Timer 1 is a 16-bit timer. When a timer interrupt occurs, the CPU (Central Processing Unit) stops the currently executing code and processes the event. This is a timer interrupt. The event that triggers the interrupt is called the interrupt source, and the function that handles the event is called the interrupt service routine. This system uses Timer 0 and Timer 2 as timer interrupt sources. The register for Timer 0 is TCNT0, and the counter register for Timer 2 is TCNT2. Both registers count from 0 to 255 and are cleared when they reach 255. In phase-corrected PWM mode, after counting to 255, they count down to 0 and then start a new round of forward counting.The output of timer 2 is OC2A / B, the final count value is 255, and the bottom is 0. However, the final count value can also be set to a number in the OCR2A register, which can be used to change the frequency of the timer's output square wave. The interrupt control PD4 and PD5 pins of timer 0 output a pair of PWM pulse square waves, and the interrupt control PD6 and PD7 pins of timer 2 output another pair of inverted PWM pulse square waves. By simply changing the timing register count interrupt value, the frequency of the output PWM pulse square wave can be changed.

[0029] In order to adjust the output pulse waveform, in some further specific examples, a pulse width modulation inverter module is used, which is a single-phase full-bridge inverter control circuit that can control the output pulse waveform of the inverter to change between 20KHz-100KHz.

[0030] To display water quality and equipment operation, in some further specific examples, the data receiving module also includes an MCGS display module. This module is widely used in industrial automation, intelligent manufacturing, process control, and other fields. On a touchscreen interface, it intuitively displays information such as equipment operating status, process flow, and parameter changes through animation and multi-state displays, enhancing the user experience and system visualization.

[0031] In order to output ultrasonic pulses, in some further specific examples, an ultrasonic pulse device is used, which is an ultrasonic generator that converts electrical energy into mechanical vibration energy through electromagnetic oscillation, thereby generating high-frequency sound waves.

In addition, the above description of the present application is based on the embodiments foreseen by the inventors, which is intended to provide a useful description, and those non-substantial changes to the present application that have not yet been foreseen may still represent equivalent changes to the present application.
