[0001] The present invention relates to the technical field of hydrogen-rich water irrigation, and in particular to a solid-state hydrogen storage irrigation machine and a method for using the same. Background Art

[0002] At present, the application of hydrogen-rich water in agricultural irrigation has made significant progress in recent years, and hydrogen-rich water irrigation technology has been applied to a variety of crops, including rice, wheat, corn, strawberry, blueberry, tomato, and Chinese cabbage. In addition, it is also suitable for the cultivation of Chinese herbal medicines.

[0003] Hydrogen-rich water irrigation can not only increase yields, but also improve the quality of agricultural products, such as improving taste and increasing nutritional content. In addition, it can enhance the disease resistance and stress resistance of crops. Hydrogen-rich water irrigation can reduce the use of fertilizers and pesticides, thereby reducing the risk of soil and water pollution. Hydrogen-rich water has strong antioxidant properties, which can effectively remove active oxygen and reduce stress damage to plants. Since hydrogen-rich water irrigation can significantly increase the yield and quality of agricultural products, it has higher economic value in the market.

[0004] At present, hydrogen-rich water irrigation technology has been applied in Qingpu District, Songjiang District, Shanghai, Lishui District, Nanjing, Danzao, Foshan and other places in China. With the continuous development of hydrogen energy agriculture, this technology is expected to be promoted in a wider range of areas. The first domestic hydrogen-rich rice planting technical regulations standard was issued in Qingpu, Shanghai in 2024. This provides a basis for the standardization and normalization of hydrogen-rich water irrigation technology, which will help its further promotion and application.

[0005] Regarding the above-mentioned related technologies, the applicant found that although hydrogen-rich water irrigation technology has many advantages, it still faces some challenges in practical applications. Among them, how to maintain high solubility and stability of hydrogen in water for a long time is an important problem currently faced. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a solid-state hydrogen storage irrigation machine and a method of using the same, which can ensure that hydrogen maintains a high solubility in water for a long time, thereby improving the stability of hydrogen-rich water.

[0007] The technical solution of the present invention to solve the above technical problems is as follows: A solid-state hydrogen storage irrigation machine comprises a chassis, a water storage device and a solid-state hydrogen storage device are arranged in the chassis, an ultrasonic vibrator is arranged at the bottom of the water storage device, an air guide pipe is arranged at the bottom of the water storage device, a plurality of air outlets are opened on the air guide pipe, the air outlets are arranged at the bottom of the air guide pipe, the air guide pipe is communicated with the solid-state hydrogen storage device, the water storage device is provided with a water outlet and a water inlet, a water pump is arranged in the chassis, the water pump is communicated with the water inlet, the solid-state hydrogen storage device is connected to a solenoid valve, and the solenoid valve is arranged between the solid-state hydrogen storage device and the water storage device.

[0008] By adopting the above technical solution, the solid-state hydrogen storage device introduces hydrogen into the water storage device through the outlet hole, and the high-frequency ultrasonic wave of the ultrasonic vibrator crushes the hydrogen bubbles into micro-nano-sized bubbles, so that the hydrogen can be more fully in contact with water, thereby increasing the storage time of hydrogen in water, maintaining a high solubility of hydrogen in water, and improving the stability of hydrogen-rich water, thereby generating hydrogen-rich irrigation water that is beneficial to the growth of crops.

[0009] Furthermore, the solid-state hydrogen storage device is provided with a pressure reducing module, and the solenoid valve is provided with an explosion-proof solenoid head.

[0010] By adopting the above technical solution, the pressure of hydrogen discharged from the solid-state hydrogen storage device is reduced through the provision of a decompression module and an explosion-proof electromagnetic head, thereby improving the safety of hydrogen discharge.

[0011] Furthermore, active metal powder is placed in the solid-state hydrogen storage device.

[0012] By adopting the above technical solution, after the active metal powder comes into contact with the hydrogen molecules, the hydrogen molecules adhere to the surface of the active metal powder to achieve the purpose of hydrogen storage. At the same time, compared with the traditional high-pressure hydrogen storage technology, the solid-state hydrogen storage technology has the characteristics of low pressure, high hydrogen storage density and good safety.

[0013] Furthermore, a plurality of pulleys are provided at the bottom of the chassis, and a handrail is provided at the top.

[0014] By adopting the above technical solution and arranging the pulley and the handrail, when people use the irrigation machine, it is convenient to carry out a series of related operations such as moving the irrigation machine, which has the effect of saving time and labor.

[0015] Furthermore, a door is provided on the side of the chassis.

[0016] By adopting the above technical solution, the box door can be opened, making it convenient for people to repair and inspect the interior of the irrigation machine.

[0017] Furthermore, an exhaust fan is provided on the side of the chassis.

[0018] By adopting the above technical solution, the exhaust fan rotates to blow the heat inside the chassis out of the chassis, achieving the effect of air cooling and heat dissipation, and ensuring the normal operation of the internal equipment of the irrigation machine.

[0019] Furthermore, a plurality of fixing frames are provided between the ultrasonic vibrator and the water storage device, and the fixing frames connect the ultrasonic vibrator and the water storage device.

[0020] By adopting the above technical solution, the fixing frame plays a role in further strengthening the stability of the connection between the ultrasonic vibrator and the water storage device.

[0021] A method for using a solid-state hydrogen storage irrigation machine comprises the following steps: Step 1: Pour water from the water inlet into the sealed water storage device by controlling the water pump; Step 2: When the water level reaches the set position, open the solenoid valve to introduce the hydrogen in the solid hydrogen storage device into the water through the air outlet, and start the ultrasonic vibrator simultaneously to break the hydrogen bubbles into micro-nano-sized bubbles, so that the hydrogen is fully mixed with the water; Step 3: When the hydrogen concentration reaches a certain level, discharge the hydrogen-rich water through the outlet and use the hydrogen-rich water for irrigation.

[0022] By adopting the above technical solution, when hydrogen enters the water through the vent, due to the small size of the vent, hydrogen mixes with water to form small bubbles. The small bubbles are broken by the vibration of the ultrasonic vibrator to form smaller micro-nano bubbles. The bubbles can remain in the water for a long time, so that the hydrogen can be more fully in contact with the water, thereby increasing the storage time of hydrogen in the water, maintaining a high solubility of hydrogen in the water, and improving the stability of hydrogen-rich water, thereby generating hydrogen-rich irrigation water that is beneficial to the growth of crops.

[0023] Furthermore, the set level of the hydrogen concentration is a hydrogen-rich water standard in which the hydrogen solubility in water reaches the requirements for irrigation.

[0024] By adopting the above technical solution, under normal conditions, the solubility of hydrogen in water is very small and cannot meet the requirements of hydrogen-rich water for irrigation. However, the vibration of the ultrasonic vibrator breaks up the hydrogen, thereby increasing the hydrogen content in the water and maintaining a high solubility of hydrogen in water.

[0025] Furthermore, the size range of the micro-nano bubbles is 10 -7 m~10 -6 m.

[0026] By adopting the above technical solution, when the bubble size is less than a certain size 10 -7 m~10 -6 m, the bubbles can remain in the water for a long time, forming hydrogen-rich water that meets irrigation requirements.

[0027] In summary, compared with the prior art, the above technical solution has the following beneficial effects: (1) The solid-state hydrogen storage device introduces hydrogen into the water storage device through the outlet hole, and the high-frequency ultrasonic wave of the ultrasonic vibrator crushes the hydrogen bubbles into micro-nano-sized bubbles, so that the hydrogen can contact the water more fully, increase the storage time of hydrogen in water, maintain a high solubility of hydrogen in water, improve the stability of hydrogen-rich water, and generate hydrogen-rich irrigation water that is beneficial to the growth of crops; (2) The pressure of hydrogen discharged from the solid-state hydrogen storage device is reduced by setting up a decompression module and an explosion-proof electromagnetic head, thereby improving the safety of hydrogen discharge; (3) After the active metal powder comes into contact with the hydrogen molecules, the hydrogen molecules adhere to the surface of the active metal powder to achieve the purpose of hydrogen storage. At the same time, compared with the traditional high-pressure hydrogen storage technology, the solid-state hydrogen storage technology has the characteristics of low pressure, high hydrogen storage density and good safety; (4) When hydrogen enters the water through the vent, due to the small size of the vent, hydrogen mixes with water to form small bubbles. The small bubbles are broken by the vibration of the ultrasonic vibrator to form smaller micro-nano bubbles. The bubbles can remain in the water for a long time, allowing the hydrogen to come into contact with the water more fully, thereby increasing the storage time of hydrogen in the water, maintaining a high solubility of hydrogen in the water, and improving the stability of hydrogen-rich water, thereby generating hydrogen-rich irrigation water that is beneficial to the growth of crops.

[0030] The principles and features of the present invention are described below in conjunction with all the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] The embodiment of the present invention discloses a solid-state hydrogen storage irrigation machine and a method of using the same.

[0032] Reference Figure 1 A solid-state hydrogen storage irrigation machine includes a chassis 1, in which a water storage device 2 and a solid-state hydrogen storage device 3 are arranged. The volume of the water storage device 2 in this embodiment can be 40L, or the water storage device 2 of different volumes can be customized according to the irrigation requirements of crops.

[0033] An ultrasonic vibrator 6 is provided at the bottom of the water storage device 2. It is recommended to provide three ultrasonic vibrators 6 at the bottom of the water storage device 2. The ultrasonic power in this embodiment is 900W, and the operating frequency is 40KHZ, or ultrasonic vibrators 6 of different powers and frequencies can be customized according to the needs of the site.

[0034] An air duct 5 is installed at the bottom of the water storage device 2. A plurality of air outlets are provided on the air duct 5. The air outlets are located at the bottom of the air duct 5. The air duct 5 is interconnected with the solid-state hydrogen storage device 3. The water storage device 2 is provided with a water outlet 22 and a water inlet 21. The water inlet 21 and the water outlet 22 are provided with pagoda-type pipe joints connected to a PU tube woven with cotton thread.

[0035] The solid-state hydrogen storage device 3 introduces hydrogen into the water storage device 2 through the air outlet, and the high-frequency ultrasonic wave of the ultrasonic vibrator 6 crushes the hydrogen bubbles into micro-nano-sized bubbles, so that the hydrogen can contact the water more fully, thereby increasing the storage time of hydrogen in water, maintaining a high solubility of hydrogen in water, and improving the stability of hydrogen-rich water, thereby generating hydrogen-rich irrigation water that is beneficial to the growth of crops.

[0036] A water pump 7 is provided in the chassis 1, and the recommended flow rate of the water pump 7 is: 2000L / hour. The water pump 7 is connected to the water inlet 21, and the solid-state hydrogen storage device 3 is connected to the solenoid valve 4. The voltage of the solenoid valve 4 is recommended to be AC220V, and the solenoid valve 4 is placed between the solid-state hydrogen storage device 3 and the water storage device 2. A decompression module is installed on the solid-state hydrogen storage device 3, and a decompression quick-change connector is recommended. An explosion-proof electromagnetic head is provided in the electromagnetic valve 4. Through the setting of the decompression module and the explosion-proof electromagnetic head, the pressure of hydrogen discharged from the solid-state hydrogen storage device 3 is reduced, and the safety of hydrogen discharge is improved.

[0037] Active metal powder is placed in the solid-state hydrogen storage device 3, and the active metal powder is used to absorb hydrogen molecules to store hydrogen. After the active metal powder contacts the hydrogen molecules, the hydrogen molecules adhere to the surface of the active metal powder to achieve the purpose of hydrogen storage. At the same time, compared with the traditional high-pressure hydrogen storage technology, the solid-state hydrogen storage technology has the characteristics of low pressure, high hydrogen storage density and good safety.

[0038] Several pulleys are installed at the bottom of the chassis 1. It is recommended to set a pulley at each corner of the bottom of the chassis 1. A handrail is installed on the top. It is recommended that the handrail is made of 6-point galvanized pipe bending. Through the setting of the pulley and the handrail, when people use the irrigation machine, it is convenient to move the irrigation machine and perform a series of related operations, which has the effect of saving time and labor.

[0039] A door is provided on the side of the chassis 1. It is recommended that the door be symmetrically arranged at the front and rear positions of the chassis 1. Opening the door makes it convenient for people to repair and inspect the interior of the irrigation machine.

[0040] An exhaust fan is installed on the side of the chassis 1. The exhaust fan rotates to blow the heat inside the chassis 1 out of the chassis 1, achieving the effect of air cooling and heat dissipation, ensuring the normal operation of the internal equipment of the irrigation machine.

[0041] Several fixing frames are provided between the ultrasonic vibrator 6 and the water storage device 2, and four U-shaped fixing frames are recommended, which connect the ultrasonic vibrator 6 and the water storage device 2. The fixing frames play a role in further strengthening the connection stability between the ultrasonic vibrator 6 and the water storage device 2.

[0042] A method for using a solid-state hydrogen storage irrigation machine comprises the following steps: Step 1: Control the water pump 7 to pour water from the water inlet 21 into the sealed water storage device 2; Step 2: When the water level reaches the set position, the solenoid valve 4 is opened to introduce the hydrogen in the solid hydrogen storage device 3 into the water through the air outlet, and the ultrasonic vibrator 6 is started synchronously to break the hydrogen bubbles into micro-nano-sized bubbles, so that the hydrogen is fully mixed with the water; Step 3: After the hydrogen concentration reaches a certain level, the hydrogen-rich water is discharged through the water outlet 22 and used for irrigation.

[0043] When hydrogen enters the water through the vent, due to the small size of the vent, hydrogen mixes with water to form small bubbles. The small bubbles are broken by the vibration of the ultrasonic vibrator 6 to form smaller micro-nano bubbles. The bubbles can remain in the water for a long time, allowing the hydrogen to contact the water more fully, thereby increasing the storage time of hydrogen in the water, maintaining a high solubility of hydrogen in the water, and improving the stability of hydrogen-rich water, thereby generating hydrogen-rich irrigation water that is beneficial to the growth of crops.

[0044] The set level of hydrogen concentration is that the solubility of hydrogen in water reaches the standard of hydrogen-rich water required for irrigation. Under normal conditions, the solubility of hydrogen in water is very small and cannot meet the requirements of hydrogen-rich water for irrigation. However, the vibration of the ultrasonic vibrator 6 breaks up the hydrogen content in the water and maintains a high solubility of hydrogen in water.

[0045] The size of the bubbles at the micro-nano level ranges from 10 -7 m~10 -6 m. When the bubble size is less than a certain size 10 - 7 m~10 -6 m, the bubbles can remain in the water for a long time, forming hydrogen-rich water that meets irrigation requirements to promote the growth of crops and increase yields.

[0046] The implementation principle of a solid-state hydrogen storage irrigation machine and a method of using the same in an embodiment of the present invention is as follows: The solid-state hydrogen storage device 3 is selected as the hydrogen source. The solid-state hydrogen storage technology places a certain amount of active metal powder in the solid-state hydrogen storage device 3. When the hydrogen molecules come into contact with the active metal powder, the hydrogen molecules can adhere to the surface of the active metal powder, thereby achieving the purpose of hydrogen storage. Compared with the traditional high-pressure hydrogen storage technology, the solid-state hydrogen storage technology has significant advantages, including low pressure, high hydrogen storage density and good safety, which makes the storage and transportation of hydrogen safer and more convenient.

[0047] After the hydrogen is introduced into the water, high-frequency ultrasonic technology is used to crush the hydrogen bubbles. Water is poured into the sealed water tank from the water inlet 21 by controlling the water pump 7. After the water level reaches the set position, the solenoid valve 4 is opened to blow the hydrogen in the solid hydrogen storage bottle into the water. At this time, the high-frequency ultrasonic vibrator 6 is started to vibrate the hydrogen bubbles at high frequency, so that they are crushed into micro-nano bubbles. Since the air outlet is small, the small bubbles formed when the hydrogen and water are mixed are broken by the vibration of the ultrasonic vibrator 6, forming smaller micro-nano bubbles. When the bubble size is smaller than a certain size (10 -7 m~10 -6 m), the bubbles can remain in the water for a longer time, so that the hydrogen can come into contact with the water more fully, thus increasing the solubility and storage time of hydrogen in water.

[0048] When the hydrogen concentration reaches a certain level, the valve of the water outlet 22 is opened, and the generated hydrogen-rich water can be used for irrigation. Since hydrogen is evenly dispersed in the water in the form of micro-nano bubbles, hydrogen-rich irrigation water has better permeability and solubility, which can be more conducive to the absorption of hydrogen by crops, thereby promoting plant growth and improving the yield and quality of crops.

[0049] In the prior art, the methods for increasing the hydrogen content in water mainly include pressure dissolution, catalyst method and ultrasonic dissolution method. However, these methods have certain limitations: Pressure dissolution method: It requires the use of sealed tanks and requires the hydrogen to reach a certain pressure. This is not only dangerous, but also when draining water, the pressure decreases and the solubility of hydrogen in water decreases, causing hydrogen to escape from the water, and the hydrogen content cannot be effectively maintained.

[0050] Catalyst method: It requires the use of precious metals such as palladium and platinum as catalysts, which is costly and not conducive to large-scale promotion and application.

[0051] In contrast, the present invention, by combining solid-state hydrogen storage technology and high-frequency ultrasonic dissolution technology, can not only effectively increase the content and storage time of hydrogen in water, but also has higher safety and economy, providing an innovative solution for agricultural irrigation. By adopting solid-state hydrogen storage technology, the danger of high-pressure hydrogen storage is avoided and the safety of the entire system is improved. Through high-frequency ultrasonic technology, hydrogen is evenly dispersed in the water in the form of micro-nano bubbles, which significantly increases the content and storage time of hydrogen in water. Hydrogen-rich irrigation water has better permeability and solubility, which can be more conducive to the absorption of hydrogen by crops, thereby promoting plant growth and increasing the yield and quality of crops. Compared with the method of using precious metal catalysts, it reduces costs, has better economy, and is conducive to large-scale promotion and application.

[0052] By combining solid-state hydrogen storage technology and high-frequency ultrasonic technology, it can not only effectively increase the hydrogen content and storage time in water, but also has higher safety and economy, providing an innovative solution for agricultural irrigation.

[0053] In summary, this paper provides an efficient, safe and economical method for preparing hydrogen-rich water for modern agricultural irrigation, which has broad application prospects and important economic value.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
