Description

Technical Field

[0001] The utility model belongs to the field of agricultural intelligent irrigation, and in particular relates to an automatic production device for nano-bubble hydrogen-rich irrigation water that can be remotely controlled. Background Art

[0002] Micro-nano hydrogen-rich water has the following effects in agricultural irrigation:

[0003] 1. Promote plant growth. Micro-nano hydrogen-rich water can quickly penetrate plant roots, providing them with abundant hydrogen and water. Hydrogen, as a bioactive substance, can promote plant cell metabolism and enhance plant photosynthesis efficiency, thereby promoting plant growth and development.

[0004] 2. Increase crop yields. Crops irrigated with micro-nano hydrogen-rich water often experience higher growth rates and yields than crops irrigated with traditional irrigation methods, as they receive more hydrogen and water. Micro-nano hydrogen-rich water also improves the soil environment and increases soil fertility, providing more favorable conditions for crop growth.

[0005] 3. Enhance crop resistance to stress. Micro-nano hydrogen-rich water can enhance crop resistance to stress, such as drought resistance, cold resistance, and disease resistance. Hydrogen can activate the antioxidant system in plants, reduce damage to plant cells caused by adversity, and thus increase crop survival rate and yield.

[0006] 4. Improve the quality of agricultural products. Agricultural products irrigated with micro-nano hydrogen-rich water often have better appearance, taste, and nutritional value. The addition of hydrogen can improve the flavor and taste of agricultural products, increase their nutritional value, and meet people's demand for high-quality agricultural products.

[0007] Existing methods for producing nanobubble hydrogen-rich water, such as those described in CN115611402A, "A Method for Producing Nanobubble High-Concentration Hydrogen-Rich Water," require a water electrolysis hydrogen generator and an air dissolving pump. The production process involves the electrolysis hydrogen generator generating hydrogen, which is then mixed with water in the form of nanoscale bubbles by the air dissolving pump to produce hydrogen-rich water.

[0008] The existing hydrogen-rich water production device cannot realize automatic operation when used in farmland irrigation operations. Since the farmland area is vast and there are few operators, the operation intensity is high and the irrigation quality is poor.

[0009] Therefore, there is an urgent need for a remote control device to remotely control multiple hydrogen-rich water production devices and realize automated hydrogen-rich water irrigation. Summary of the Invention

[0010] In order to solve the problem of low automation level of existing hydrogen-rich water production devices for irrigation, the utility model provides a remotely controlled automatic production device for nanobubble hydrogen-rich irrigation water. A hydrogen sensor is provided to detect the hydrogen content. Combined with a PLC controller, a hardware foundation is provided for realizing PID control of a water electrolysis hydrogen generator and an air dissolving pump. In addition, a host computer is provided to send instructions to the PLC controller. The PLC controller and the host computer communicate remotely through a wireless communication module to realize remote control of the hydrogen-rich water production device.

[0011] In order to achieve the above-mentioned object, the utility model proposes a remotely controllable automatic production device for nanobubble hydrogen-rich irrigation water, comprising a hydrogen-rich water production device, the hydrogen-rich water production device comprising an electrolytic water hydrogen generator and an air dissolving pump, and further comprising a PLC controller, a hydrogen sensor and a host computer, wherein the input end of the PLC controller is connected to the output end of the hydrogen sensor, the PLC controller is connected to a frequency converter, and the PLC controller is electrically connected to the electrolytic water hydrogen generator and the air dissolving pump respectively through the frequency converter, the electrolytic water hydrogen generator is connected to a gas pipeline, the other end of the gas pipeline is connected to the air dissolving pump, and the other end of the air dissolving pump is connected to a storage box;

[0012] The hydrogen sensor is arranged on the storage box;

[0013] The PLC controller is communicatively connected to a host computer, and both the host computer and the PLC controller are provided with wireless communication modules.

[0014] Furthermore, there are multiple hydrogen-rich water production devices, and one PLC controller is provided for each of the multiple hydrogen-rich water production devices;

[0015] The number of the corresponding water electrolysis hydrogen generator, dissolved air pump and frequency converter is multiple;

[0016] The PLC controller is connected to the frequency converter for communication. The PLC controller controls the frequency converter to connect to the power supply through a relay. The water electrolysis hydrogen generator and the dissolved air pump are connected to the power supply through the frequency converter to form a loop.

[0017] In farmland irrigation operations, the area of land to be irrigated is large at the same time, so multiple water electrolysis hydrogen generators are required to irrigate different divided areas. In order to reduce operating costs, multiple hydrogen-rich water production devices are controlled by a PLC controller.

[0018] Furthermore, there are multiple hydrogen sensors, and the multiple hydrogen sensors are connected to an acquisition card, which includes an MCU chip. The output ends of the multiple hydrogen sensors are connected to the ADC pins of the MCU chip. An RS232 serial port is set between the MCU chip and the PLC controller, and the MCU chip and the PLC controller are connected through the RS232 serial port.

[0019] Since multiple hydrogen-rich water production devices are controlled by a PLC controller, multiple hydrogen sensors need to be connected to a PLC controller for data transmission. However, the PLC controller interface is limited and the price of adding new modules is high. Therefore, an acquisition card is set up. The acquisition card includes an MCU chip with an editable internal program, providing the hardware basis for automatically uploading detection parameters.

[0020] Furthermore, the storage box is provided with a water outlet pipe, and a solenoid valve is provided on the water outlet pipe. The coil of the solenoid valve is electrically connected to the PLC controller.

[0021] Furthermore, the wireless communication module includes one or more combinations of a 4G module, a NB-Iot module and a LoRa module.

[0022] Through the above technical solution, the beneficial effects of the utility model are:

[0023] This utility model enables remote control of a hydrogen-rich water production device and simultaneous control of multiple hydrogen-rich water production devices. A hydrogen sensor is provided on a storage tank for detecting the hydrogen content of the nanobubble hydrogen-rich water. The hydrogen sensor is connected to a PLC controller, providing the hardware foundation for the PLC controller to control the operating power of the electrolytic water hydrogen generator and the dissolved air pump based on the hydrogen content. Furthermore, a host computer is provided to issue control instructions to the PLC controller, and a wireless communication module is provided between the host computer and the PLC controller for communication. This allows operators to remotely control the PLC controller to achieve automatic irrigation of farmland. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The hydrogen sensor 4 is arranged on the storage box;

[0031] The PLC controller 3 is communicatively connected to a host computer 5 , and both the host computer 5 and the PLC controller 3 are provided with a wireless communication module 7 .

[0032] There are multiple hydrogen-rich water production devices, and one PLC controller 3 is provided for each of the multiple hydrogen-rich water production devices;

[0033] The corresponding number of the water electrolysis hydrogen generator 1, the dissolved air pump 2 and the frequency converter 6 is multiple;

[0034] The PLC controller 3 is in communication with the frequency converter 6 , and the PLC controller 3 controls the frequency converter 6 to connect to the power supply through a relay. The water electrolysis hydrogen generator 1 and the dissolved air pump 2 are respectively connected to the power supply through the frequency converter 6 to form a loop.

[0035] There are multiple hydrogen sensors 4, and the multiple hydrogen sensors 4 are connected to an acquisition card. The acquisition card includes an MCU chip 8.

[0037] The wireless communication module 7 includes one or more combinations of a 4G module, a NB-Iot module and a LoRa module.

[0038] Since the operation process of multiple hydrogen-rich water production devices is the same as the operation process of one hydrogen-rich water production device, in this embodiment, the operation process of one hydrogen-rich water production device is used as an example for description:

[0039] During operation, a staff member sends a start signal via the host computer 5.
