Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, specifically to a hydrogen-rich water precision irrigation spray device. Background Technology

[0002] Extensive practical and experimental results have shown that irrigation with hydrogen-rich water has a significant effect on regulating and promoting crop growth and improving stress resistance. It also effectively improves the soil environment (optimizing soil microbial communities and alleviating soil degradation and compaction). Therefore, hydrogen-rich water is increasingly widely used in modern agricultural planting and irrigation processes. Chinese patent document CN222148524U discloses an irrigation device for tomato cultivation. This device converts solar energy into electrical energy using photovoltaic panels and stores it in a battery. The battery powers the cathode and anode rods, allowing irrigation water to enter a hydrogen-rich water generation tank. The water is then electrolyzed by the cathode and anode rods to produce hydrogen gas, resulting in hydrogen-rich water. Irrigating tomato seedlings with this hydrogen-rich water promotes seed germination and seedling growth, making irrigation more diverse. However, during the electrolysis of irrigation water and the generation of hydrogen, hydrogen gas escapes from the water in the form of bubbles (the solubility of hydrogen in water is only about 0.0016 g / L under standard atmospheric pressure and 25°C). This means that the hydrogen solubility of the hydrogen-rich water produced by this device during actual irrigation is low. At the same time, the hydrogen solubility in the irrigation device is uneven, resulting in uneven hydrogen solubility in the irrigation water, which leads to differences in irrigation effect and uneven crop growth. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a hydrogen-rich water precision irrigation spray device. This spray device can not only effectively prevent hydrogen from escaping and ensure the solubility and uniformity of hydrogen in water, but also achieve uniform irrigation of crops and avoid uneven crop growth due to irrigation differences.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A hydrogen-rich water precision irrigation spraying device includes a base plate. From left to right, a water storage tank, a gas storage tank, an electrolytic cell, a mixing tank, and a spraying assembly are arranged on the end face of the base plate. A vertical diaphragm is set in the middle of the electrolytic cell to separate the oxygen production zone and the hydrogen production zone. An anode rod and a cathode rod are respectively set at the bottom of the electrolytic cell and on both sides of the diaphragm. The anode rod is located on the side closer to the gas storage tank, and the gas storage tank and the corresponding side wall of the electrolytic cell are connected by a gas guide pipe. The cathode rod is located on the side closer to the mixing tank, and the mixing tank and the corresponding side wall of the electrolytic cell are connected by a gas guide pipe. The water storage tank is connected to the inner cavity of the electrolytic cell and the mixing tank through a water outlet pipe to supply water to the electrolytic cell and the mixing tank. A coaxial rotating rod is set in the middle of the mixing tank, and multiple mixing rods are evenly arranged on the outer wall of the rotating rod. A coaxial aeration cylinder is set on the inner wall of the bottom of the mixing tank. Multiple aeration holes are evenly arranged on the inner wall of the aeration cylinder, and one side wall of the aeration cylinder is connected to the end of the gas guide pipe located in the cathode rod area. The mixing tank and the spraying assembly are connected.

[0006] Based on further optimization of the above scheme, a walking mechanism is provided on the bottom surface of the base plate to control the entire spraying device to move in the field.

[0007] Based on further optimization of the above scheme, an outlet pipe is provided on the top surface of the gas storage tank, and a one-way valve and an oxygen concentration sensor are installed on the outlet pipe.

[0008] Based on further optimization of the above scheme, the diaphragm can be either an anion exchange membrane or a cation exchange membrane.

[0009] Based on further optimization of the above scheme, the anode rod and cathode rod are electrically connected to the anode and cathode of the battery on the base plate, respectively.

[0010] Based on further optimization of the above scheme, a water pump is installed between the mixing tank and the spraying assembly. The input end of the water pump is connected to the inner cavity of the mixing tank through a water guide pipe, and the output end of the water pump is connected to the spraying assembly through a water guide pipe.

[0011] Based on further optimization of the above scheme, the spray assembly includes a spray pipe, a bracket and a rotating nozzle. There are multiple brackets, which are fixedly installed on the end face of the base plate and have slots at their top corresponding to the spray pipe. The spray pipe is fixedly inserted into the slots and the middle part of the spray pipe is connected to the output end water pipe of the water pump. Rotating nozzles are respectively installed at both ends of the spray pipe.

[0012] The following are the technical effects of this utility model:

[0013] This application utilizes the combination of an electrolytic cell, a diaphragm, and cathode and anode rods to simultaneously generate oxygen and hydrogen through water electrolysis, while isolating the hydrogen and oxygen gases. This avoids problems such as impurities in hydrogen-rich water preparation and reduced hydrogen solubility due to hydrogen-oxygen mixing. Simultaneously, the inclusion of a gas storage tank allows for the effective collection of oxygen generated during water electrolysis, which can then be used in other oxygen-required applications, thus maximizing the utilization of the electrolysis products. The combination of an aeration cylinder, rotating rod, and stirring rod not only introduces hydrogen generated during water electrolysis into the mixing tank in gaseous form but also promotes uniform mixing and dissolution of hydrogen and water through continuous stirring and rotation, breaking up the gas produced during aeration. This improves both the solubility and uniformity of the hydrogen-rich water, thereby preventing problems such as inconsistent growth and poor irrigation effects caused by irrigation with hydrogen-rich water with low or uneven hydrogen solubility.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1:

[0020] A hydrogen-rich water precision irrigation sprinkler system includes a base plate 10, with a walking mechanism installed on the bottom surface of the base plate 10 for controlling the movement of the entire sprinkler system in the field; combined with Figure 1 and Figure 2As shown, in this embodiment, a walking mechanism is provided at each of the four corners of the bottom surface of the base plate 10, including a walking frame 11, a hub shaft 12, and a walking wheel 13.

[0021] From left to right, the bottom plate 10 is equipped with a water storage tank 20, a gas storage tank 30, an electrolytic cell 40, a stirring tank 50, and a spray assembly; a vertical diaphragm 41 is installed in the middle of the electrolytic cell 40 to separate the oxygen production area from the hydrogen production area (e.g., ...). Figure 1 As shown), the diaphragm 41 can be either an anion exchange membrane or a cation exchange membrane (the choice can be made according to the actual situation, and this embodiment does not impose too many limitations, which will be understood by those skilled in the art). An anode rod 42 and a cathode rod 43 are respectively arranged at the bottom of the electrolytic cell 40 and on both sides of the diaphragm. The anode rod 42 is located on the side closer to the gas storage tank 30 (i.e., Figure 1 (As shown on the left) and the gas storage tank 30 and the corresponding side walls of the electrolytic cell 40 are connected by a gas guide pipe, with the cathode rod 43 located on the side closest to the stirring tank 50 (i.e. Figure 1 (As shown on the right) The stirring tank 50 and the corresponding side walls of the electrolytic cell 40 are connected by gas guide pipes (electric valves for controlling the opening and closing of the gas guide pipes are provided on the gas guide pipes; in addition, in order to facilitate better gas delivery and avoid gas backflow, a vacuum pump and a one-way valve can also be provided on the gas guide pipes. The vacuum pump and the one-way valve can adopt conventional structures and models in the art, which can be understood by those skilled in the art); the anode rod 42 and the cathode rod 43 are respectively electrically connected to the anode and cathode of the battery set on the base plate 10 (the battery can adopt common structures and models in the art, and no further limitations are made in this embodiment). The top surface of the gas storage tank 30 is provided with a gas outlet pipe, and a one-way valve and an oxygen concentration sensor (such as Figure 1 As shown; meanwhile, the gas storage tank 30 is fixedly mounted on the end face of the base plate 10 via a positioning bracket. The water storage tank 20 is connected to the inner cavities of the electrolysis cell 40 and the stirring tank 50 via water outlet pipes (e.g., Figure 1 As shown), it is used to supply water to the electrolytic cell 40 and the mixing tank 50 (at the same time, an electric valve for controlling the conduction is set at the branch pipe of the water outlet at the electrolytic cell 40 and the mixing tank 50, and a water pump is set inside the water storage tank 20).

[0022] A coaxial rotating rod 52 is provided in the middle of the mixing tank 50, and multiple stirring rods 53 are evenly arranged on the outer wall of the rotating rod 52. (The rotation of the rotating rod 52 is controlled by a rotary motor 520 located on the top surface of the mixing tank 50.) Figure 1 or Figure 2(As shown); a coaxial aeration cylinder 51 is provided on the inner wall of the bottom of the mixing tank 50. Multiple aeration holes are evenly distributed on the inner wall of the aeration cylinder 51, and one side wall of the aeration cylinder 51 is connected to the end of the air guide pipe located in the cathode rod 43 area (in conjunction with...). Figure 1 and Figure 3 As shown, the aeration cylinder 51 has an annular cross-section and multiple tiny aeration holes are evenly arranged in its inner ring. An annular cavity is opened inside the aeration cylinder and the annular cavity is connected to the air guide pipe located in the cathode rod 43 area. The aeration holes are connected to the annular cavity.

[0023] The mixing tank 50 is connected to the spray assembly; specifically, a water pump 60 is installed between the mixing tank 50 and the spray assembly. The input end of the water pump 60 is connected to the inner cavity of the mixing tank 50 through a water guide pipe, and the output end of the water pump 60 is connected to the spray assembly through a water guide pipe (e.g., ...). Figure 1 (As shown). The spray assembly includes a spray pipe 61, a bracket 62, and a rotating nozzle 63. There are multiple brackets 62 (generally no fewer than two, such as...). Figure 2 As shown, this embodiment uses two brackets 62, which are fixedly mounted on the end face of the base plate 10, and their top ends have slots corresponding to the spray pipe 61. The spray pipe 61 is fixedly engaged in the slots (achieving both installation and fixation of the spray pipe 61; at the same time, to prevent axial slippage of the spray pipe 61, two positioning rings are fixedly sleeved on the outer wall of the spray pipe 61 and the corresponding brackets 62, respectively. The distance between the two positioning rings is slightly larger than the width of the bracket 62. The spray pipe 61 is fixed in position by being engaged on both sides of the corresponding brackets 62). The middle part of the spray pipe 61 is connected to the output end water guide pipe of the water pump 60, and rotating nozzles 63 are respectively provided at both ends of the spray pipe 61 (e.g., Figure 2 As shown, water outlet nozzles are provided at the bottom of both ends of the spray pipe 61, and the rotating nozzle 63 is rotatably sleeved on the outer wall of the water outlet nozzle.

[0024] Working principle:

[0025] In use, water is first supplied to the electrolytic cell 40 and the stirring tank 50 by the water pump inside the water storage tank 20 until the required liquid level is reached (the liquid level is identified by the liquid level sensors installed in the electrolytic cell 40 and the stirring tank 50 respectively); then, the water pump in the water storage tank 20 and the electric valve on the water outlet pipe are closed, and the anode rod 42 and the cathode rod 43 are started to generate oxygen and hydrogen through water electrolysis, and the gas production area is separated by the diaphragm 41; simultaneously, the electric valves on the two gas guide pipes are opened to allow oxygen to enter the gas storage tank 30 for oxygen collection. (The oxygen concentration in the gas storage tank 30 is detected by an oxygen concentration sensor. When the oxygen concentration reaches the threshold, the gas storage tank 30 is replaced.) Hydrogen enters the mixing tank 50 through the aeration cylinder 51. At this time, the rotating rod 52 and the stirring rod 53 are turned on to break up the bubbles and stir the water during the aeration process, thereby increasing the solubility of hydrogen and the uniform mixing of hydrogen and water. Then, the entire spraying device is moved in the field and the liquid in the mixing tank 50 is pumped into the spray pipe 61 by the water pump 60. The hydrogen-rich water is sprayed using the rotating nozzle 63.

[0026] Example 2:

[0027] As another preferred embodiment of the present invention, based on the above embodiment 1, the rotating nozzle 63 is controlled to rotate by a micro motor set on the lower side of the spray pipe 61. Specifically, the outer wall of the rotating end of the rotating nozzle 63 is fixedly sleeved with a driven gear, and a micro motor is set on the lower side of the spray pipe 61 corresponding to the rotating nozzle, and the output shaft of the micro motor is fixedly sleeved with a drive gear, and the drive gear meshes with the driven gear.

[0028] Example 3:

[0029] As another preferred embodiment of this utility model, based on the above embodiment 1, liquid level sensors are respectively installed in the inner cavity of the electrolytic cell 40 and the inner cavity of the stirring tank 50 to obtain the water volume in the corresponding tank.
