[0002] In plant growth experiments, rainfall is an important research factor that directly affects the growth and development of plants in the wild environment. Current experiments on rainfall control usually interfere with rainfall, collect the actual rainfall in some target fields, and add rainwater to the control target fields to obtain plant growth conditions in different target fields.

[0003] Currently, rainfall is usually controlled by setting up fixed rain shields or tarpaulins directly on the target fields. In order to collect rainwater, the width and length of the rain shields or tarpaulins are relatively large, which leads to marginal effects in the target fields where part of the rainfall is collected, affecting the data of the control test and causing inaccurate data collection.

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0044] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0045] For ease of description, spatial relative terms may be used in the text to describe the relative positional relationship or movement of an element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be further oriented and rotated 90 degrees or in other directions and the spatial relative descriptors used in the text are interpreted accordingly.

[0046] like Figures 1 to 3 As shown, in some exemplary embodiments of the present application, a rainwater distribution device is provided, which is applied to rainwater distribution control of multiple target fields 100, and mainly includes: a rainwater collection component 10 and a water storage tank 20, the rainwater collection component 10 includes a fixed water delivery trough 11 and a plurality of movable rainwater collecting troughs 12, the rainwater collecting troughs 12 can slide relative to the water delivery trough 11 and are always connected to the water delivery trough 11, and the rainwater collecting troughs 12 are erected above the target fields; the water storage tank 20 is connected to the output end of the water delivery trough 11, and includes a pumping structure 21 and an output pipeline 22, and the output pipeline 22 is connected to the spraying components 30 of other target fields.

[0047] When the rainwater distribution device described above is used, the rainwater collection operation in the target field 100 can be achieved. Since the rainwater collecting trough 12 is in a movable setting, the rainwater collecting trough 12 can be displaced during the rainy period. In this way, a specific area of ​​the target field 100 will not be fixedly blocked for a long time, thereby avoiding the occurrence of marginal effect.

[0048] It should be clear that the rain shielding area of ​​the rain collecting trough 12 is fixed, and its coverage ratio relative to the target field 100 is also equal. During the reciprocating motion of the rain collecting trough 12, the coverage ratio for the target field 100 is always maintained at the same level, and the coverage effect on the target field 100 presents a uniform and cyclical trend. Based on this, the amount of rainfall received in the entire target field 100 can be kept consistent. Moreover, compared with the target field 100 as a control, the amount of rainfall inside it can be accurately and effectively controlled.

[0049] In addition, the water storage tank 20 has the function of temporarily storing rainwater, and the temporarily stored rainwater comes from the rainwater collected by the rainwater collecting trough 12. When carrying out the control work for the rainfall of the control target field 100, the rainwater temporarily stored in the water storage tank 20 can be transported to the spray assembly 30 corresponding to the control target field 100 by relying on the conveying system constructed by the pumping structure 21 and the output pipeline 22 inside the water storage tank 20, so as to realize the real-time addition of rainfall to the control target field 100. Not only that, according to the specific experimental needs, it is also possible to choose to transport the rainwater in the water storage tank 20 at a specific time point in the future, so as to achieve the operation of delayed addition of rainfall. Through these two different rainfall addition methods, multiple sets of different control experimental data can be obtained.

[0050] It should be noted that in terms of water source composition, the composition of rainwater is different from that of tap water and ordinary irrigation water. Tap water contains substances such as chlorine that remain after purification treatment, and the composition of irrigation water often varies depending on the water source and treatment process. In contrast, the formation of rainwater originates from the natural water vapor cycle, has not undergone a complex artificial purification process, and its composition is more natural. In the control experiment scenario, if tap water or ordinary irrigation water is used, the additional substances contained in this type of water source are very likely to intervene in the experimental system, change the physical and chemical properties of the soil, microbial communities, etc., and then interfere with the growth environment of the plant, and ultimately have a negative impact on the accuracy and reliability of the control experiment. The use of rainwater, due to its composition characteristics, can maintain the natural state of the experimental environment to the greatest extent and ensure the validity of the control experiment results.

[0051] On the other hand, rainwater collection creates convenient conditions for sample collection. The collected rainwater can be properly preserved as an independent sample, and researchers can use professional testing equipment and analysis methods to accurately measure key indicators such as mineral content, pH, microbial species and quantity in rainwater samples. These data not only help to gain a deeper understanding of the local climate environment and air quality, but also lay a solid data foundation for subsequent related research work such as plant nutrition and soil improvement, and provide key information for theoretical derivation and technology development.

[0052] In addition, from the perspective of practical operational convenience and reducing human interference, the situation is particularly prominent when facing specific target vegetation. Some rare or special target vegetation often grows in areas with rugged terrain, inconvenient transportation, and difficult to reach quickly by humans. If traditional irrigation methods are used, not only will a lot of manpower and material resources be consumed to transport water sources and irrigation equipment to the target location, but the frequent entry and exit of personnel is also likely to damage the original ecological environment around the vegetation, causing unnecessary human interference such as trampling on the soil to cause it to become hardened and disturbing the surrounding animal communities. The rainwater collection device can be pre-placed in a suitable position around the target vegetation. Without frequent human intervention, it can complete water replenishment with the help of natural precipitation, which greatly improves the convenience of operation and reduces various types of interference caused by human intervention on the vegetation growth environment.

[0053] See also Figure 3 , Figure 4 as well as Figure 6 In some exemplary embodiments of the present application, the rainwater distribution device also includes a sliding assembly 40, the sliding assembly 40 includes a sliding rail 41 and a plurality of sliding blocks 42, the sliding blocks 42 are slidably connected to the sliding rail 41, the sliding rail 41 is connected to the water supply trough 11, and the extension direction of the sliding rail 41 is the same as the extension direction of the water supply trough 11, and the sliding blocks 42 are connected to the corresponding rainwater collecting trough 12.

[0054] A slidable connection is established between the sliding block 42 and the sliding track 41 , that is, the sliding block 42 can freely move back and forth along the sliding track 41 .

[0055] The sliding track 41 is connected to the water delivery trough 11, and the extension direction of the sliding track 41 is the same as the extension direction of the water delivery trough 11. The sliding track 41 is connected to the water delivery trough 11, and the two are firmly connected. In terms of spatial layout, the extension path of the sliding track 41 is consistent with the extension direction of the water delivery trough 11. Such a setting makes the sliding direction of the rain collecting trough 12 consistent with the extension direction of the water delivery trough 11, thereby preventing the rain collecting trough 12 from falling off from the water delivery trough 11 and ensuring the collection of rainwater.

[0056] The arrangement of the plurality of sliding blocks 42 is adapted to the plurality of rainwater collecting gutters 12 . When the target field 100 has a relatively long span, the distribution of the plurality of sliding blocks 42 has a good effect on increasing or decreasing the coverage area of ​​the rainwater collecting gutters 12 .

[0057] The introduction of the sliding assembly 40 provides the necessary physical basis for the sliding of the rain collecting trough 12, and the sliding action between the sliding track 41 and the sliding block 42 is controllable. With the help of corresponding control means, it is possible to ensure that the rain collecting trough 12 can achieve uniform sliding. During the rainfall process, the uniformly sliding rain collecting trough 12 shows a uniform characteristic in covering the target field 100. Since the rain collecting trough 12 moves at a uniform speed, its shielding area is continuously and regularly replaced, so that the rainfall received at each position of the target field 100 can maintain a consistent state, avoiding the occurrence of local uneven rainfall.

[0058] The arrangement of multiple sliding blocks 42 is compatible with multiple rainwater collecting gutters 12. The target field 100 often has a long span. This layout is very important. The coverage area of ​​a single rainwater collecting gutter 12 is limited. A larger coverage area is required to achieve the preset coverage ratio. If a single rainwater collecting gutter 12 is set, it will not only improve the overall quality of the rainwater collecting gutter 12 and increase the load capacity requirements of the sliding component 40, but also affect the overall sliding efficiency of the rainwater collecting gutter 12. When the rainfall is small, uneven coverage is prone to occur. When multiple rainwater collecting gutters 12 are used to work together, the corresponding multiple sliding blocks 42 can be arranged in an orderly manner on the sliding track 41 according to the actual size of the target field 100 and the distribution plan of the rainwater collecting gutter 12, reducing the load requirements of the sliding component 40 and increasing the adaptability of the rainwater collecting gutter 12.

[0059] In actual operation, by adjusting the distribution of the plurality of sliding blocks 42, the coverage area of ​​the rain collecting trough 12 can be precisely controlled. For example, when the coverage area needs to be expanded, the spacing between the sliding blocks 42 can be appropriately changed to make the connection between adjacent rain collecting troughs 12 closer, reduce the gap, and thus increase the overall coverage area; conversely, if the coverage area needs to be reduced, the spacing between the sliding blocks 42 can be appropriately widened to open a certain distance between the rain collecting troughs 12, and the purpose can be achieved. In this way, the reasonable distribution of the plurality of sliding blocks 42 shows a good effect for flexibly controlling the coverage area of ​​the rain collecting trough 12.

[0060] See also Figure 3 , Figure 4 as well as Figure 6 In some exemplary embodiments of the present application, the water delivery trough 11 is a U-shaped trough, and the opening of the water delivery trough 11 is vertically upward; the output end of the rain collecting trough 12 extends into the water delivery trough 11 along the opening, and the sliding track 41 is arranged on the side of the water delivery trough 11 away from the opening, and the sliding track 41 and the sliding block 42 limit each other in the vertical direction.

[0061] The U-shaped groove is set in a downwardly concave structure, and the output end of the rainwater collecting trough 12 extends smoothly into the water delivery trough 11 along the opening of the water delivery trough 11, so as to achieve communication between the two and ensure that the collected rainwater can be smoothly collected into the water delivery trough 11.

[0062] At the same time, the sliding track 41 is placed on the side of the water delivery trough 11 away from the opening, that is, at the bottom of the water delivery trough 11. This layout arrangement allows the sliding track 41 to form a specific spatial relationship with the rain collecting trough 12 above, the opening of the water delivery trough 11 and other components in the vertical dimension. In addition, a mutual limiting mechanism in the vertical direction is constructed between the sliding track 41 and the sliding block 42. This arrangement allows the sliding track 41 to suspend the sliding block 42, and the sliding block 42 only has the freedom to slide along the sliding track 41. This arrangement can effectively constrain the displacement of the sliding block 42 in the vertical direction and avoid unnecessary up and down shaking, thereby ensuring that the rain collecting trough 12 maintains a stable and precise operating state when sliding along the sliding track 41, laying the foundation for the continuous and smooth advancement of rainwater collection work.

[0063] See also Figure 5 In some exemplary embodiments of the present application, the bottom surface of the water delivery trough 11 is defined as the water delivery surface 111. The water delivery surface 111 is not arranged parallel to the horizontal plane, but is arranged at a certain angle, which is about 5°. With such an inclined angle design, once rainwater falls into the water delivery trough 11, it will flow along the inclined water delivery surface 111 in a predetermined fixed direction due to the action of gravity. Compared with the horizontally arranged bottom surface of the trough, this structure with an inclined angle greatly improves the fluidity of rainwater in the water delivery trough 11, making the collection process smoother and more efficient, and the subsequent transfer operation of rainwater to other components or areas is also more convenient, which creates favorable conditions for the stable operation of the entire rainwater distribution device and the efficient use of rainwater.

[0064] See also Figure 5 In some exemplary embodiments of the present application, the lower end of the water delivery surface 111 is connected to a water outlet 113, and the water outlet 113 is connected to the water storage tank 20 for water storage. When rainwater continues to flow along the inclined water delivery surface 111 under the action of gravity, it will eventually converge to the lower end of the water delivery surface 111 and flow into the water storage tank 20 through the water outlet 113. In this way, the collected rainwater can smoothly enter the water storage tank 20, achieving the purpose of water storage, and providing a stable water source guarantee for the subsequent rainwater distribution device to allocate rainwater on demand and carry out various application scenarios such as experimental control and precision irrigation.

[0065] See also Figures 3 to 5In some optional embodiments of the present application, a baffle 112 is provided at the opening of the water delivery trough 11. The cross-section of the baffle 112 is an L-shaped structure, one wall of which is connected to the side wall of the water delivery trough 11 away from the rain collecting trough 12, and the other wall covers the entire opening of the water delivery trough 11. During the rainwater collection operation, rainwater will fall on the top area of ​​the water delivery trough 11. Due to the existence of the baffle 112, the rainwater falling on the top area of ​​the water delivery trough 11 is effectively blocked and cannot directly enter the water delivery trough 11 and then flow into the water storage tank 20. In this way, the amount of rainwater actually entering the water storage tank 20 can be accurately controlled to avoid the mixing of this part of extra rainwater, which will cause interference in rainfall distribution to the immediate rainfall enhancement control experiment, and ensure that the rainfall enhancement control experiment can be carried out in an orderly manner based on accurate and stable rainfall settings to obtain reliable experimental data.

[0066] Furthermore, the retaining cover 112 is tilted, and the horizontal height of the end of the retaining cover 112 close to the rain collecting trough 12 is higher than the end of the retaining cover 112 away from the rain collecting trough 12. Such a tilted layout allows the rainwater falling on the retaining cover 112 to flow naturally in the direction away from the rain collecting trough 12 under the action of gravity. This design not only conforms to the characteristics of rainwater flowing under gravity, but also prevents rainwater from accidentally flowing into the water delivery trough 11 from the side close to the rain collecting trough 12, thereby more accurately and stably controlling the amount of rainwater entering the water delivery trough 11 and the water storage tank 20, maintaining the stability of the operation of the rainwater distribution device, and ensuring the accuracy of subsequent related experiments or irrigation operations.

[0067] See also Figures 3 to 5 In some exemplary embodiments of the present application, the sliding block 42 includes an L-shaped extension arm, which is detachably connected to the bottom surface of the rainwater collecting gutter 12.

[0068] From the perspective of spatial structure, the extension arm starts from the bottom surface of the water delivery trough 11, stretches toward the direction close to the rain collection trough 12, and then, with the help of the L-shaped corner, continues to extend until it fits the bottom surface of the rain collection trough 12. Thanks to this special direction, the extension arm cleverly avoids contact with the side of the water delivery trough 11 or the rain collection trough 12, eliminating potential interference risks, allowing the various components to operate without obstructing each other, and ensuring the smooth operation of the device.

[0069] At the same time, in terms of the overall structural layout, the sliding block 42 and the sliding track 41 are both located on the bottom of the water delivery trough 11, and the rain collection trough 12 is deeply inserted into the bottom of the water delivery trough 11. In addition, the L-shaped extension arm is firmly connected from the bottom of the water delivery trough 11 to the bottom of the rain collection trough 12, which facilitates the close cooperation between the rain collection trough 12 and the water delivery trough 11 in multiple positions. On the one hand, the multi-directional connection relationship forms a stable mechanical structure, greatly reducing the possibility of the rain collection trough 12 falling off from the water delivery trough 11, and significantly enhancing the tightness of the combination of the two; on the other hand, such a structure enables the rain collection trough 12 to always be firmly inside the water delivery trough 11 during the entire operation process, ensuring that the rainwater collection operation is not disturbed, and further improving the rain collection effect.

[0070] The extension arm and the bottom surface of the rain collecting trough 12 are connected in a detachable manner. Specifically, the connection means between the two can be a fastening connection, using screws, nuts and other connectors to firmly lock the extension arm and the bottom surface of the rain collecting trough 12 together, so that the two form a stable whole that can withstand various forces during the sliding process of the rain collecting trough 12; or it can be a bonding method, using an appropriate adhesive, applying it on the contact surface, and after it solidifies, the effect of stable connection is also achieved, so that the extension arm and the rain collecting trough 12 can be easily disassembled during subsequent equipment maintenance and component replacement.

[0071] like Figure 4 and Figures 6 to 8 As shown, in some exemplary embodiments of the present application, the rain collecting gutter 12 includes an extension portion 126, which extends downward from one side end of the rain collecting gutter 12 and extends into the water delivery trough 11. The length of the extension portion 126 is less than the minimum length of the depth of the water delivery trough 11, thereby ensuring that the extension portion 126 can achieve effective connection and cooperation inside the water delivery trough 11, and will not cause abnormal conditions such as interference or collision due to being too long.

[0072] The connection position of the extension arm is located on the side of the extension part 126 away from the water supply trough 11, so that a more reasonable and stable connection structure is formed among the extension arm, the rain collecting trough 12 and the water supply trough 11, which not only strengthens the installation stability of the rain collecting trough 12 in the water supply trough 11, but also lays a solid foundation for the subsequent sliding operation of the rain collecting trough 12 following the sliding block 42 along the sliding track 41, ensuring that the entire rainwater distribution device stably and efficiently performs rainwater collection and distribution tasks.

[0073] like Figure 3 As shown, in some exemplary embodiments of the present application, the sliding assembly 40 further includes a driving member 43 and a transmission pair 44, the transmission pair 44 is connected to the sliding block 42, and the driving member 43 drives the sliding block 42 to slide along the sliding track 41 through the transmission pair 44. The driving member 43 serves as a power source, and with the help of the transmission pair 44, provides the sliding block 42 with the driving force required to slide along the sliding track 41.

[0074] In an optional embodiment, the driving member 43 is a motor. The motor has stable and continuous power output characteristics and can accurately control the output torque and speed. The matching transmission pair 44 is selected as a thread pair, specifically a ball screw thread pair. The ball screw thread pair combines the advantages of high precision and high efficiency. It uses the ball to roll between the screw and the nut to greatly reduce the friction resistance, thereby efficiently and accurately converting the rotational motion output by the motor into linear motion, driving the sliding block 42 connected to it to slide smoothly and evenly along the sliding track 41, creating ideal conditions for the precise displacement of the rainwater collecting trough 12, and ensuring that the rainwater collection and distribution work is carried out in an orderly manner.

[0075] See also Figure 3 In some exemplary embodiments of the present application, the rainwater distribution device also includes a support frame 60, the support frame 60 includes a bottom insertion rod and a frame body, the driving member 43 and the transmission pair 44 are both arranged on the frame body, and the insertion rod is inserted into the ground to fix the support frame 60.

[0076] In some exemplary embodiments of the present application, the rainwater collecting trough 12 is made of transparent material. Since the rainwater collecting trough 12 needs to be installed above the target field, if it is made of non-transparent material, it is very likely to block the sunlight and have a negative impact on the lighting conditions of the field. The use of transparent materials perfectly avoids this problem. In actual use scenarios, sunlight can penetrate the transparent wall of the rainwater collecting trough 12 without hindrance and directly shine on the field below, fully ensuring the normal lighting needs of the field and maintaining the photosynthesis of crops without interference.

[0077] At the same time, the bottom surface 121 of the rain collecting trough 12 is inclined with respect to the horizontal direction, and the water delivery trough 11 is located at one end of the rain collecting trough 12 close to the target field. At the same time, the bottom surface 121 of the rain collecting trough 12 is not placed horizontally, but is inclined with respect to the horizontal direction. In the layout of the entire rainwater distribution device, the water delivery trough 11 is located at one end of the rain collecting trough 12 close to the target field. In this way, the rainwater falling into the rain collecting trough 12 will flow along the inclined bottom surface 121 toward the water delivery trough 11 under the action of gravity, and then flow into the water delivery trough 11 more smoothly and efficiently, laying a good foundation for the subsequent rainwater collection, storage and redistribution process.

[0078] like Figure 6 As shown, in some exemplary embodiments of the present application, the rainwater distribution device also includes a photovoltaic component 50, and the photovoltaic component 50 includes an electrically connected photovoltaic panel 51 and a battery 52; the photovoltaic panel 51 is responsible for capturing solar energy and converting it into electrical energy, which is then transmitted to the battery 52 for storage, so as to provide stable power supply when electricity is needed later.

[0079] A transparent first trough 122 and a second trough 123 are sequentially arranged on one side of the rainwater collecting trough 12 close to the target field. The battery 52 is located in the first trough 122, and the photovoltaic panel 51 is located in the second trough 123. Both the first trough 122 and the second trough 12 have good light transmittance. The battery 52 is properly placed inside the first trough 122. Thanks to the transparent characteristics of the first trough 122, it does not block the sunlight too much, and has little impact on the lighting environment of the target field below. At the same time, the photovoltaic panel 51 is placed in the second trough 123. The transparent material of the second trough 123 allows sunlight to penetrate smoothly, allowing the photovoltaic panel 51 to fully receive solar energy, ensuring the stable operation of the entire photovoltaic assembly 50, and continuously delivering electrical energy to the relevant electrical equipment of the rainwater distribution device.

[0080] The battery 52 can provide the required electrical energy for important components such as the driving member 43, the pumping structure 21 and the control component 71. The driving member 43, as the power source of the sliding component 40, needs electric drive to drive the sliding block 42 to slide on the sliding track 41, thereby realizing the movement operation of the rainwater collecting trough 12; the pumping structure 21 needs electricity to drive its operation, pumping the rainwater in the water storage tank 20 to the spraying component 30 of the target field through the output pipeline 22, so as to realize the reasonable distribution of rainwater; the control component 71 needs electricity to ensure its normal operation, so as to effectively control the operation status of the entire device.

[0081] At the same time, after combining with the photovoltaic panel 51, the energy supply of the entire system is greatly optimized. The photovoltaic panel 51 can convert solar energy into electrical energy to charge the battery 52. ​​When there is sufficient sunlight, the photovoltaic panel 51 continuously replenishes energy for the battery 52 so that the battery 52 stores enough electrical energy. This combination effectively achieves energy self-sufficiency, which has significant advantages for target fields located in remote locations. Since it is usually difficult to set up power lines in remote areas, traditional power supply methods are not only costly but also difficult to construct. Through the cooperation of the photovoltaic components 50 and the battery 52 of the rainwater distribution device, the system can operate normally without external power lines, realizing automated rainwater collection, storage and distribution operations, reducing dependence on external power infrastructure, greatly improving the applicability and convenience of the device, and also providing the possibility for the application of the device in a variety of different environments, ensuring the stability of energy supply and reliability of operation of the device during long-term use.

[0082] In some exemplary embodiments of the present application, the length of the water delivery trough 11 is greater than the side length of the target field, the span of the rainwater collecting trough 12 along the length direction of the water delivery trough 11 is between 25% and 60% of the side length of the target field, and the portion of the water delivery trough 11 that exceeds the side length of the target field is at least greater than or equal to 35% of the span of the rainwater collecting trough 12 along the length direction of the water delivery trough 11.

[0083] Such a length setting can ensure that the water delivery trough 11 has enough space to receive and transport rainwater, providing a wider range for subsequent rainwater distribution.

[0084] The span of the rainwater collecting trough 12 along the length of the water delivery trough 11 is limited to 25% to 60% of the side length of the target field. The purpose of limiting the span range is to reasonably control the size and rainwater collecting capacity of the rainwater collecting trough 12 while ensuring the rainwater collecting effect, so as to avoid it being too large or too small to affect the overall rainwater distribution efficiency and uniformity.

[0085] In addition, the portion of the water delivery trough 11 that exceeds the side length of the target field has further length requirements, and the length of the excess portion must be at least greater than or equal to 35% of the span of the rainwater collecting trough 12 along the length direction of the water delivery trough 11. This restriction ensures that the water delivery trough 11 has enough space in the portion that exceeds the target field, so as to more flexibly handle the sliding of the rainwater collecting trough 12 and the transmission of rainwater, and avoid problems such as jamming or rainwater overflow when the rainwater collecting trough 12 slides due to insufficient space. At the same time, it also provides a more reliable guarantee for the stable operation of the entire rainwater distribution device and the effective collection and distribution of rainwater. Through these careful designs on the length, the relationship between the water delivery trough 11 and the rainwater collecting trough 12 can be better coordinated, the device's performance in collecting and distributing rainwater can be optimized, and the device's applicability and working efficiency on target fields of different sizes can be improved.

[0086] like Figure 7 As shown, in some exemplary embodiments of the present application, the rainwater collection assembly 10 includes a symmetrically arranged water delivery trough 11 and a plurality of movably arranged rainwater collecting troughs 12, and the rainwater collecting troughs 12 on both sides are arranged one by one and fixedly connected together.

[0087] This symmetrically arranged water delivery trough 11 can ensure that the rainwater receiving and conveying on both sides are more balanced and stable during the rainwater collection process, providing a relatively symmetrical and stable water source foundation for the subsequent rainwater distribution operation. The multiple movable rainwater collecting troughs 12 play a core rainwater collection function in this component. In particular, the rainwater collecting troughs 12 on both sides are arranged in a one-to-one correspondence, and they are fixedly connected together. By fixing the rainwater collecting troughs 12 on both sides, the overall structural stability of the rainwater collecting trough 12 can be enhanced, so that it can maintain good synchronization and integrity during the sliding process, avoiding the incoordination problems caused by the independent movement of a single rainwater collecting trough 12, and ensuring that the rainwater collecting troughs 12 on both sides can work together during rainwater collection and sliding operations, providing more reliable guarantees for uniform coverage of the target field. At the same time, this symmetrical and fixedly connected design method also helps to simplify the operating process, reduce the risk of failures that may occur due to structural asymmetry or unstable connection, and improve the working efficiency and reliability of the entire rainwater collection component 10.

[0088] Furthermore, if Figure 7 As shown, in some exemplary embodiments of the present application, a connecting groove 80 is further provided between two symmetrically arranged water delivery grooves 11, and the connecting groove 80 is connected between the two rain collecting grooves 12, and its length is equal to the length of the rain collecting groove 12. The connecting groove 80 is provided to adapt to a target field 100 with a longer width, and can be adjusted according to the width of the connecting groove 80.

[0089] When facing a long target field 100, it is difficult to achieve comprehensive and uniform coverage by relying solely on conventional rainwater collecting troughs 12. The connecting trough 80 can be flexibly adjusted according to its own width. By changing its width parameter, the rainwater collection device can fit target fields 100 of different width specifications, broadening the scope of application of the entire rainwater collection component, ensuring that the rainwater collection task can be efficiently completed under various width conditions, and laying a solid foundation for subsequent rainwater distribution and utilization.

[0090] Furthermore, if Figure 7 As shown, in some exemplary embodiments of the present application, the connecting groove 80 can be connected to the rain collecting groove 12 through a joint 125 on the rain collecting groove 12, or adjacent rain collecting grooves 12 can be connected through a joint 125, and the joint 125 is an extended plate body on the baffle 124, and fasteners are provided on the joint 125 for locking connection.

[0091] like Figure 1 As shown, in some exemplary embodiments of the present application, a fluid flow meter 221 and a flow control valve 222 are provided between the output pipeline 22 and the spray assembly 30 .

[0092] The main function of the fluid flow meter 221 is to accurately measure the liquid flow through the output pipeline 22. Through real-time monitoring of the flow, we can obtain the specific flow data of rainwater flowing through the output pipeline 22, which is essential for the precise control and management of the entire rainwater distribution system. For example, when conducting experimental control, the fluid flow meter 221 can accurately know the amount of rainwater delivered to the target field, and then evaluate the experimental effects under different conditions.

[0093] The flow control valve 222 is mainly used to control the rainwater flow in the output pipeline 22. According to actual needs, by adjusting the opening of the flow control valve 222, the amount of rainwater entering the spray assembly 30 from the output pipeline 22 can be flexibly adjusted to achieve precise control of the spraying amount. For example, when different irrigation intensities need to be implemented for the target field, the flow rate can be changed by adjusting the flow control valve 222 to meet different experimental conditions or crop growth requirements. At the same time, the flow control valve 222 is used in conjunction with the fluid flow meter 221, and the flow rate can be accurately adjusted according to the flow data measured by the fluid flow meter 221 to achieve the required flow target, further ensuring the accuracy and adjustability of rainwater distribution, and improving the controllability and reliability of the entire rainwater distribution system.

[0094] In some exemplary embodiments of the present application, a rainwater distribution device is also set up on the control field, and one or more spray ports are set up below the second trough body 123. The spray ports are connected to the spray assembly 30, and the rainwater to be sprayed is transported through the pumping structure 21. In conjunction with the sliding rainwater collecting trough 12, the sprayed rainwater is more uniform, which is conducive to the accuracy of the control experiment.

[0095] In some exemplary embodiments of the present application, the setting of the rainwater distribution device is not limited to the purpose of the control experiment, and the rainfall can also be controlled for certain specific vegetation or crops to ensure better growth of the plants. Specifically, the control experiment on wild forage grass can be targeted at Elymus danglingii, Kobresia dwarfus, Polygonum villosa, etc., and the growth control of economic crops can be applied to quinoa, oats, lettuce, broad beans, etc. The above embodiments are not limited to the plants and vegetation mentioned, but are only exemplary embodiments pointed out.

[0096] like Fig. 9 As shown, in some exemplary embodiments of the present application, a control component 71 is also provided in the rainwater distribution device, and the photovoltaic panel 51, the battery 52, the pumping structure 21, the fluid flow meter 221, and the flow control valve 222 are electrically connected to the control component 71. The control component 71 can be connected to the remote terminal 73 through the communication module 72 and receive control from the remote terminal.

[0097] With the help of the communication module 72, the control component 71 can also build a signal connection bridge with the remote terminal 73. The remote terminal 73 can be a computer, a smart phone or a dedicated monitoring device. Even if the operator is thousands of miles away, he can use this connection to send instructions to the control component 71. For example, based on the flow data fed back by the fluid flow meter 221, if the remote operator finds that the amount of rainwater delivered to the field deviates from the preset value, he can immediately issue instructions to the control component 71 through the remote terminal 73 to accurately control the opening of the flow control valve 222, or adjust the working parameters of the pumping structure 21 as needed, so as to truly achieve remote control and make the operation and maintenance management of the rainwater distribution device more intelligent, efficient and convenient.
