The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0033] In the embodiment of the present application, the hydrogen fertilizer produced by the hydrogen fertilizer generating device 100 can be transported to the fertilizing mechanism 220 through the fertilizer delivery pipeline 300, and then the mobile mechanism 210 drives the fertilizing mechanism 220 to fertilize the plants in various areas in the greenhouse body; in this way, the number of fertilizing devices 200 can be flexibly set in the greenhouse body as needed, and one group of hydrogen fertilizer generating devices 100 can be used to supply hydrogen fertilizer to multiple groups of fertilizing devices 200, which is beneficial to reducing the setting cost of the greenhouse body hydrogen fertilization system structure, and the hydrogen fertilizer generating device 100 does not need to move with the fertilizing mechanism 220, which can not only save the energy consumption of the mobile mechanism 210, but also facilitate the setting of protective measures for the hydrogen generating device, which helps to improve the safety of use and is conducive to large-scale application.

[0034] Please refer to Figure 1-4The embodiment of the present application provides a greenhouse main body hydrogen fertilization system structure, including a hydrogen fertilizer generating device 100, a fertilizing device 200 and a fertilizer delivery pipeline 300, wherein the fertilizing device 200 includes a mobile mechanism 210 and a fertilizing mechanism 220 disposed on the mobile mechanism 210, and the fertilizer delivery pipeline 300 includes a fixed portion 310 and a follower portion 320, wherein the fixed portion 310 is connected to the hydrogen fertilizer generating device 100, and the follower portion 320 is connected to the fertilizing mechanism 220. The fertilizer delivery pipeline 300 is used to transport the hydrogen fertilizer generated by the hydrogen fertilizer generating device 100 to the fertilizing mechanism 220, and the mobile mechanism 210 is used to drive the fertilizing mechanism 220 to move in the greenhouse main body, thereby applying hydrogen fertilizer to plants in various regions. Among them, the fertilizing device 200 can be arranged in one group, two groups or multiple groups in the greenhouse main body as needed to ensure that the fertilization area can fully cover the plant planting area in the greenhouse main body.

[0035] In one embodiment, referring to Figure 1 and Figure 2 The hydrogen fertilizer generating device 100 includes a hydrogen generator 110 and a hydrogen-water mixer 120. The hydrogen generator 110 is used to generate hydrogen. The hydrogen-water mixer 120 includes a mixing box 121. The mixing box 121 is provided with an air inlet 122, a water inlet 123 and a water outlet 124. The air inlet 122 is connected to the hydrogen outlet of the hydrogen generator 110. The water inlet 123 is used to communicate with a water supply source. The water outlet 124 is connected to the fixed portion 310 of the fertilizer delivery pipeline 300. The hydrogen generated by the hydrogen generator 110 is transported into the hydrogen-water mixer 120 and mixed with water to generate hydrogen fertilizer (i.e., hydrogen-rich water), which is then transported to the fertilization mechanism 220 for fertilization by the fertilizer delivery pipeline 300. Exemplarily, the hydrogen generator 110 and the hydrogen-water mixer 120 are arranged in the greenhouse body, the hydrogen generator 110 is an electrolytic hydrogen generator 110, the hydrogen-water mixer 120 is a microbubble generator, and the bubble generating chamber of the microbubble generator is the mixing box 121. In other embodiments, the hydrogen generator 110 may also be an alkaline liquid hydrogen generator 110 or other types of hydrogen generators 110, and the hydrogen-water mixer 120 may also be a vortex mixer or a static mixer or other gas-water mixing equipment, and the selection of the hydrogen generator 110 and the hydrogen-water mixer 120 can meet the design and use requirements.

[0036] In one embodiment, referring to Figure 2 A pressure relief valve 125 is provided on the mixing box 121 to prevent excessive pressure in the mixing box 121, which helps to ensure the safety of the use of the hydrogen-water mixer 120.

[0037] In one embodiment, referring to Figure 2A one-way valve 111 is provided between the air inlet 122 and the hydrogen outlet of the hydrogen generator 110. The one-way valve 111 allows hydrogen to flow from the hydrogen outlet of the hydrogen generator 110 to the air inlet 122 in one direction to prevent hydrogen from flowing back from the air inlet 122 into the hydrogen generator 110, thereby helping to improve the safety of the use of the hydrogen generator 110.

[0038] In one embodiment, referring to Figure 1 and Figure 3 The mobile mechanism 210 includes a guide rail 211 and a mobile seat 212. The guide rail 211 is used to be fixed on the frame in the greenhouse body. The mobile seat 212 is movably arranged on the guide rail 211. The fertilization mechanism 220 is installed on the mobile seat 212. The mobile seat 212 is used to drive the fertilization mechanism 220 to move along the guide rail 211 in the greenhouse body. Exemplarily, the guide rail 211 is arranged in the greenhouse body along the length direction of the greenhouse body. The mobile seat 212 is an electric traveler suspended on the guide rail 211, and the mobile seat 212 can move along the guide rail 211. In other examples, the guide rail 211 can also be arranged along the width direction of the greenhouse body or other directions as needed.

[0039] In one embodiment, referring to Figure 1 and Figure 3 A plurality of follower hangers 2111 are also suspended on the guide rail 211. The follower hangers 2111 are slidably arranged on the guide rail 211. The follower hangers 2111 are provided with pipe holes. The follower part 320 passes through the pipe holes and is fixed to the follower hangers 2111 at intervals, so that the follower part 320 is fixed to the follower hanger 2111 in sections, so that the follower part 320 moves with the movement of the fertilizing device 200.

[0040] In one embodiment, referring to Figure 1 and Figure 3 The fertilization mechanism 220 includes a telescopic component 221, a mounting frame 222, a rotating component 223 and a soil-inserting column 224. The telescopic component 221 is arranged on the mobile seat 212, the mounting frame 222 is arranged at the telescopic end of the telescopic component 221, the soil-inserting column 224 is rotatably connected to the mounting frame 222, and the rotating component 223 is fixedly mounted on the mounting frame 222. The rotating component 223 is used to drive the soil-inserting column 224 to deflect. The telescopic component 221 is used to drive the soil-inserting column 224 to be inserted into the soil, and can control the depth of the soil-inserting column 224 inserted into the soil according to the telescopic length; the rotating component 223 can drive the soil-inserting column 224 to rotate to adjust the soil-inserting angle of the soil-inserting column 224. The coordinated arrangement of the telescopic component 221 and the rotating component 223 enables the soil-inserting depth and angle of the soil-inserting column 224 to be adjusted according to the fertilization needs of different plants, which is conducive to realizing refined fertilization and improving the utilization rate of hydrogen fertilizer.

[0041] For example, refer to Figure 1 and Figure 3 The telescopic component 221 is specifically a multi-stage electric telescopic rod. The telescopic component 221 is fixed on the mobile seat 212 along the height direction of the greenhouse body. The mounting frame 222 is fixed on the telescopic end of the telescopic component 221. The mounting frame 222 is rotatably connected to a fertilizer pipe 225 along the horizontal axis on the side away from the telescopic component 221. The follower 320 of the fertilizer delivery pipeline 300 is connected to the fertilizer pipe 225. A plurality of soil insertion columns 224 are connected to the fertilizer pipe 225 at intervals along the axis direction of the fertilizer pipe 225. The soil insertion column 224 is rotatably connected to the mounting frame 222 through the fertilizer pipe 225. The rotating component 223 is a servo motor. The rotating component 223 is fixed on one side of the mounting frame 222 and is coaxially connected to the fertilizer pipe 225 to drive the fertilizer pipe 225 to rotate, thereby driving the soil insertion column 224 to deflect and adjust the soil insertion angle of the soil insertion column 224. After the rotating component 223 drives the soil-inserting column 224 to rotate, the axis of the soil-inserting column 224 will form an angle with the telescopic direction of the telescopic component 221. In this way, as the telescopic component 221 is extended and retracted, the soil-inserting column 224 is actually pressed into the soil instead of being inserted into the soil along the axis of the soil-inserting column 224. Therefore, due to the limitation of structural strength, it is usually only applicable to the situation where the soil-inserting column 224 needs to be inserted at a smaller angle.

[0042] In other embodiments, if the plants in the greenhouse body need the soil column 224 to be inserted into the soil at a larger angle, a telescopic rod for adjusting the insertion angle can be added to the fertilization mechanism 220. Specifically, the telescopic rod is rotatably connected to the mounting frame 222, the output shaft of the rotating assembly 223 is coaxially connected to the rotating shaft of the telescopic rod, and the fertilization main pipe 225 is fixed to the telescopic end of the telescopic rod. In this way, the telescopic assembly 221 is used to drive other parts to approach the soil. After approaching the soil, the rotating assembly 223 drives the telescopic rod to rotate around its own axis, thereby driving the soil column 224 to deflect, and then the telescopic rod is extended and retracted, so that the soil column 224 can be obliquely inserted into the soil.

[0043] In other embodiments, if the plants in the greenhouse body have the same requirements for the soil insertion angle of the soil insertion column 224, or have a lower requirement for the soil insertion angle, the fertilization mechanism 220 can also be set as only the telescopic component 221 and the soil insertion column 224. For example, the fixed part 310 of the telescopic component 221 is fixed on the movable seat 212, the soil insertion column 224 is installed at the telescopic end of the telescopic component 221, and is coaxially arranged with the telescopic component 221. The follower part 320 of the fertilizer delivery pipeline 300 is connected to the soil insertion column 224 and communicates with the accommodating cavity of the soil insertion column 224. In this way, the soil insertion depth of the soil insertion column 224 can be controlled only by the telescopic component 221, which helps to reduce the cost of the fertilization mechanism 220.

[0044] In one embodiment, referring to Figure 4The soil-inserting column 224 has a hollow accommodating cavity, and the insertion end of the soil-inserting column 224 for inserting into the soil is provided with a first fertilization port 2241 connected to the accommodating cavity. In addition, by limiting the diameter of the first fertilization port 2241 and setting the soil-inserting end of the soil-inserting column 224 to be conical, the soil-entering condition of the first fertilization port 2241 during the insertion process can be effectively improved, which helps to prevent the first fertilization port 2241 from being blocked. After the soil-inserting column 224 is inserted into the soil, the hydrogen fertilizer is sent into the accommodating cavity and then transported into the soil. A small part of the soil that enters the first fertilization port 2241 during the insertion process of the soil-inserting column 224 will be flushed out by the hydrogen fertilizer in this process.

[0045] In one embodiment, referring to Figure 4 A second fertilizer port 2242 is provided on the side wall of the soil column 224 so as to inject hydrogen fertilizer into the surrounding side of the soil column 224, thereby expanding the injection range of hydrogen fertilizer and facilitating absorption by plant roots.

[0046] In one embodiment, referring to Figure 4 , the fertilizer delivery direction of the second fertilizer port 2242 is tilted relative to the axis of the soil column 224, and the angle between the fertilizer delivery direction of the second fertilizer port 2242 and the insertion direction of the soil column 224 is an obtuse angle. In this way, on the one hand, it is not easy for the soil to enter the second fertilizer port 2242 during insertion, causing the second fertilizer port 2242 to be blocked; on the other hand, it is helpful to form a hole with an opening tilted downward in the soil along the direction of the second fertilizer port 2242 when hydrogen fertilizer is injected into the soil, and the escaped hydrogen is trapped after entering the hole, increasing the retention time. Exemplarily, a plurality of second fertilizer ports 2242 are arranged on the side wall of the soil column 224, and the angle between the fertilizer delivery direction of the second fertilizer port 2242 and the insertion direction of the soil column 224 is 135°. In other embodiments, 120°, 150° or other angles can also be selected to meet the needs of use.

[0047] In one embodiment, referring to Figure 1, and also includes an environmental monitoring system and a central control system (not shown in the figure). The environmental monitoring system includes a sensor 400 for being arranged in the greenhouse body. The sensor 400 is used to collect environmental parameters in the greenhouse body. The environmental parameters include one or more of temperature, humidity, light, carbon dioxide concentration, and hydrogen concentration; the central control system is electrically connected to the environmental monitoring system, the hydrogen fertilizer generating device 100, the mobile mechanism 210, and the fertilizing mechanism 220. Exemplarily, the sensor 400 adopts an integrated sensor that can detect temperature, humidity, light, carbon dioxide concentration and hydrogen concentration. Multiple sensors 400 are dispersed in the greenhouse body. The central control system is a controller, and the controller is electrically connected to the hydrogen generator 110, the hydrogen-water mixer 120, the movable seat 212, the telescopic assembly 221 and the rotating assembly 223. The central control system can receive the environmental parameter data (temperature, humidity, light intensity, light time, carbon dioxide concentration and hydrogen concentration) collected by each sensor 400, and control the hydrogen generator 110, the hydrogen-water mixer 120, the movable seat 212, the telescopic assembly 221 and the rotating assembly 223 to work according to the received environmental parameter data, so as to apply hydrogen fertilizer to the plants in the greenhouse body.

[0048] In a further embodiment, an intelligent adjustment system (not shown in the figure) electrically connected to the environmental monitoring system is also included. The intelligent adjustment system is also a controller. The intelligent adjustment system is used to electrically connect to the parameter control terminal in the greenhouse body. The parameter control terminal includes a lighting system, an air conditioning system, and a humidity control system. The intelligent adjustment system can adjust the parameter control terminal in the greenhouse body according to changes in environmental parameters to adjust the environmental parameters in the greenhouse body so that the environment in the greenhouse body remains the most suitable environment for plant growth in the greenhouse body. The intelligent adjustment system can be implemented by existing technology. In other embodiments, the parameter control terminal electrically connected to the intelligent adjustment system can also be set to one or two of the lighting system, air conditioning system, and humidity control system as needed.
