Description

Technical Field

[0001] The present application relates to the technical field of agricultural irrigation, and in particular to a precipitation simulation device. Background Art

[0002] In the field of agricultural research, simulated precipitation equipment is an important experimental tool and is widely used to explore the effects of different rainfall conditions on plant growth. Such equipment usually consists of a stable support structure with multiple water-shielding tiles set at an angle. The water-shielding tiles are designed to partially block natural rainfall, allowing rainwater to flow through the gaps between the tiles and onto the vegetation below, thereby simulating different rainfall intensities and patterns.

[0003] In order to collect the rainwater guided by the tiles, the equipment is also equipped with water pipes connected to the inclined bottom of the tiles. These water pipes guide the rainwater into a water tank connected to the bracket to achieve centralized collection of rainwater. This design not only helps to reduce the amount of precipitation in the experimental area, but also provides researchers with a means to quantify rainfall and analyze its specific impact on plant growth.

[0004] The width and spacing of existing water-shielding tiles are fixed and cannot be flexibly adjusted according to experimental needs. This limitation means that researchers cannot directly adjust the amount of rainwater irrigation to plants by changing the spacing of water-shielding tiles, thus limiting the application range of the device in simulating irrigation needs under different rainfall conditions.

[0005] Therefore, the present application provides a precipitation simulation device to solve the above problems. Summary of the invention

[0006] The present application provides a precipitation simulation device, which aims to solve the problem that the width and spacing of the existing water-shielding tiles mentioned in the background technology are fixed and cannot be flexibly adjusted according to experimental requirements. This limitation means that researchers cannot directly adjust the amount of rainwater irrigation for plants by changing the spacing of the water-shielding tiles, thereby limiting the application scope of the device in simulating irrigation needs under different rainfall conditions.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a simulated precipitation device, comprising a bracket, a mounting frame plate obliquely arranged on the bracket, a plurality of rain shielding structures arranged on the mounting frame plate in an array manner, a diversion box fixedly arranged on the bracket and corresponding to the rain shielding structure and used to divert rainwater on the rain shielding structure, and a water tank arranged on the bracket and connected to the diversion box;

[0008] In order to adjust the distance between adjacent rain-shielding structures according to the width of the rain-shielding structure, and then change the amount of rainwater used to irrigate vegetation: the rain-shielding structure includes roller rods symmetrically arranged on the installation frame, rain-shielding cloths rolled on the roller rods at both ends, positioning rods arranged between the two roller rods corresponding to the upper end of the rain-shielding cloth and connected to the lower end of the installation frame, and a driving mechanism for driving the two roller rods to move closer or farther relative to each other. When it is necessary to simulate rainfall and irrigate vegetation, the spacing of the rain-shielding structure is first adjusted according to the irrigation needs of the vegetation. The driving mechanism drives the roller rods to move closer or farther relative to each other, so that the rain-shielding cloth is rolled up or unrolled on the roller rods, thereby realizing the precise adjustment of the spacing of the rain-shielding structure. Subsequently, the simulated precipitation equipment starts to work, and rainwater falls from the gap of the rain-shielding structure to simulate the natural rainfall process. The guide box collects rainwater on the rain-shielding structure and guides it to the water tank for storage. When irrigation is required, the rainwater in the water tank can be transported to the vegetation area through the irrigation system for irrigation.

[0009] In order to conveniently adjust the width of the tarpaulin by controlling the distance between the two rollers, and then adjust the width between adjacent tarpaulins: the driving mechanism includes a driving rod symmetrically rotated and plugged on the mounting frame, a plurality of sets of sliding sleeves sleeved on the driving rod and connected to the roller rod for rotation, a plurality of sets of external threads oppositely arranged on the driving rod and threadedly connected to the sliding sleeve for driving the adjacent sliding sleeves to move closer or farther relative to each other, a driving motor fixedly mounted on one end of the mounting frame for controlling the forward and reverse rotation of the driving rod, and a synchronizing member arranged on the other end of the mounting frame for making the two driving rods rotate in the same direction. When it is necessary to adjust the width of the tarpaulin, the driving motor is first started to drive the driving rod to rotate. Under the action of the synchronizing member, the two driving rods will keep rotating in the same direction. As the driving rod rotates, the two sliding sleeves of the same group will move closer or farther relative to each other along the axis direction of the driving rod, thereby driving the roller rod and the tarpaulin to move together. When the sliding sleeve moves to the preset position, the driving motor stops rotating, and at this time, the width of the tarpaulin and the distance between adjacent tarpaulins have reached the optimal state. In this way, precise control of rainfall intensity and irrigation amount can be achieved to meet the irrigation needs of different vegetation.

[0010] Preferably, in order to facilitate the drainage of rainwater on the tarpaulin: the tarpaulin is rolled up on the roller rod from bottom to top, and a water guide groove is formed between the two roller rods and the tarpaulin. The tarpaulin is rolled up from bottom to top and the design of the water guide groove enables rainwater to flow into the collection system more quickly and more concentratedly, thereby improving the collection efficiency of rainwater. The retention time of rainwater on the tarpaulin is reduced, reducing the possibility of water evaporation, thereby ensuring that more rainwater can be effectively utilized.

[0011] Preferably, in order to ensure smooth water diversion in the water diversion channel: the positioning rod and the two roller rods are arranged in a triangle so that the awning cloth is in a V shape. The design of the V-shaped awning cloth makes it easier for rainwater to flow along the water diversion channel into the diversion box at the lower end, thereby improving the water diversion efficiency.

[0012] Preferably, in order to increase the service life of the tarpaulin: the tarpaulin is PVC coated cloth or PU coated cloth. Both PVC coated cloth and PU coated cloth have excellent weather resistance, wear resistance and corrosion resistance, and can resist the erosion of wind, rain, sunlight and pollutants, thereby extending the service life of the tarpaulin. PU coated cloth has better softness and elasticity, making it easier to fold, curl and install the tarpaulin, improving the user experience.

[0013] Preferably, in order to facilitate the tarpaulin to be always in a taut state: the end of the sliding sleeve close to the roller rod is fixedly connected to a clockwork shaft, and the rotating shaft of the clockwork shaft is fixedly connected to the end of the roller rod. The design of the clockwork shaft ensures that the tarpaulin is always in a taut state during the expansion or contraction process, thereby improving the rainproof effect and aesthetics. Since the tarpaulin is always in a taut state, it can better resist the impact of wind and other external forces, thereby improving the stability of the entire rainproof structure.

[0014] Preferably, in order to facilitate the installation of the drive motor: a first installation groove for installing the drive motor is opened at one end of the installation frame plate, the drive motor is fixedly installed in the first installation groove by bolts, and the output end of the drive motor is fixedly connected to the end of the drive rod. The design of the first installation groove makes the installation of the drive motor simpler and faster. The user only needs to embed the drive motor into the first installation groove and fix it with bolts, without complicated debugging and calibration.

[0015] Preferably, in order to facilitate the power supply to the drive motor: a battery is arranged in the first installation slot, and a photovoltaic panel connected to the battery is fixedly installed on the installation frame plate. By integrating the battery and the photovoltaic panel, efficient use of solar energy can be achieved. This not only reduces the operating cost of the equipment, but also reduces the dependence on traditional energy, which is in line with the green and sustainable development concept of modern society. The introduction of the battery provides a stable power supply for the drive motor, ensuring the continuous and smooth operation of the equipment.

[0016] Preferably, the synchronous member includes a synchronous gear fixedly mounted on the end of the driving rod and a synchronous belt meshingly mounted on the two synchronous gears. By adopting a combined design of synchronous gears and synchronous belts, the two driving rods can be operated synchronously. This not only improves the stability and reliability of the equipment, but also ensures the stability and consistency of the awning during the unfolding and retracting process.

[0017] Preferably, in order to facilitate the protection of the synchronous parts: a second mounting groove for mounting the synchronous gear and the synchronous belt is provided at the other end of the mounting frame. By providing a dedicated mounting and protection space for the synchronous parts, the stability and reliability of the equipment are improved. This helps to ensure the stability and consistency of the awning during the unfolding and retracting process, thereby improving the overall performance of the simulated precipitation equipment. The design of the second mounting groove helps to prevent dust, moisture and other impurities from damaging the synchronous parts, thereby extending their service life. This reduces the maintenance cost of the equipment and improves the economic efficiency of the equipment.

[0018] Preferably, in order to conveniently drain the water in the diversion box to the inside of the water tank, a drainage port is provided at the lower end of the diversion box, a diversion pipe is plugged into the inside of the drainage port, and the bottom of the diversion pipe is plugged into the top of the water tank. By providing the drainage port and designing the plugging method of the diversion pipe, the drainage efficiency of the simulated precipitation equipment is improved. This helps to ensure that the water inside the diversion box can be discharged in a timely and smooth manner, thereby avoiding the problem of water accumulation and leakage.

[0019] This application can accurately control the rainfall intensity and irrigation amount by adjusting the spacing of the rainproof structure, and can be adjusted according to different environmental and climatic conditions, and is suitable for various vegetation irrigation scenarios. By collecting and using rainwater for irrigation, the waste of water resources is reduced, which is in line with the concept of environmental protection. Through the design of the driving mechanism, the width of the rainproof cloth can be accurately controlled, thereby adjusting the distance between adjacent rainproof cloths to meet the irrigation needs of different vegetation.

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only 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 creative work are within the scope of protection of this application.

[0030] This embodiment provides a precipitation simulation device, such as Figure 1-7 As shown, the precipitation device comprises a bracket 1, a mounting frame plate 2 obliquely arranged on the bracket 1, a plurality of rain shielding structures 3 arranged on the mounting frame plate 2 in an array manner, a guide box 4 fixedly arranged on the bracket 1 and corresponding to the rain shielding structure 3 and used to guide rainwater on the rain shielding structure 3, and a water tank 5 arranged on the bracket 1 and connected to the guide box 4;

[0031] In order to adjust the distance between adjacent rain-shielding structures 3 by adjusting the width of the rain-shielding structure 3, and then change the amount of rainwater irrigation for vegetation: the rain-shielding structure 3 includes a roller rod 31 symmetrically arranged on the mounting frame 2, a rain-shielding cloth 32 with two ends rolled on the roller rod 31, a positioning rod 33 arranged between the two roller rods 31 at the upper end of the rain-shielding cloth 32 and connected to the lower end of the mounting frame 2, and a driving mechanism 34 for driving the two roller rods 31 to move closer or farther relative to each other; by adjusting the spacing of the rain-shielding structure 3, the rainfall intensity and irrigation amount can be accurately controlled, which can be adjusted according to different environmental and climatic conditions and is suitable for various vegetation irrigation scenes. By collecting and using rainwater for irrigation, the waste of water resources is reduced, which is in line with the concept of environmental protection. When it is necessary to simulate rainfall and irrigate vegetation, the spacing of the rain-shielding structure 3 is first adjusted according to the irrigation needs of the vegetation. The driving mechanism 34 drives the roller rod 31 to move closer or farther relative to each other, so that the rain-shielding cloth 32 is rolled up or unrolled on the roller rod 31, thereby realizing the precise adjustment of the spacing of the rain-shielding structure 3. Then, the simulated precipitation equipment starts to work, and rainwater falls from the gap of the rain shielding structure 3, simulating the natural rainfall process. The guide box 4 collects rainwater on the rain shielding structure 3 and guides it to the water tank 5 for storage. When irrigation is needed, the rainwater in the water tank 5 can be transported to the vegetation area through the irrigation system for irrigation.

[0032] In order to conveniently adjust the width of the awning 32 by controlling the distance between the two rollers 31, and then adjust the width between the adjacent awnings 32: the driving mechanism 34 includes a driving rod 341 symmetrically rotated and plugged on the mounting frame 2, a plurality of sets of sleeves 342 sleeved on the driving rod 341 and connected to the roller 31 for rotation, a plurality of sets of external threads 343 oppositely opened on the driving rod 341 and threadedly connected to the sleeves 342 for driving the adjacent sleeves 342 to move closer or farther relative to each other, a driving motor 344 fixedly mounted on one end of the mounting frame 2 for controlling the forward and reverse rotation of the driving rod 341, and a synchronizing member 345 arranged at the other end of the mounting frame 2 for making the two driving rods 341 rotate in the same direction. Among them, the driving mechanism 34 is made of high-strength, corrosion-resistant stainless steel material, and is designed with precision bearings, sealing devices and synchronizing members 345 to ensure stable rotation performance and synchronization during long-term use. Through the design of the driving mechanism 34, the unfolding width of the tarpaulin 32 can be precisely controlled, thereby adjusting the distance between adjacent tarpaulins 32 to meet the irrigation needs of different vegetation. When it is necessary to adjust the unfolding width of the tarpaulin 32, first start the driving motor 344 to drive the driving rod 341 to rotate. Under the action of the synchronization member 345, the two driving rods 341 will keep rotating in the same direction. As the driving rod 341 rotates, the two sliding sleeves 342 in the same group will move closer or farther along the axial direction of the driving rod 341, thereby driving the roller rod 31 and the tarpaulin 32 to move together. When the sliding sleeve 342 moves to the preset position, the driving motor 344 stops rotating, and the unfolding width of the tarpaulin 32 and the distance between adjacent tarpaulins 32 have reached the optimal state. In this way, the rainfall intensity and irrigation amount can be precisely controlled to meet the irrigation needs of different vegetation.

[0033] Specifically, in order to facilitate the drainage of rainwater on the awning 32: the awning 32 is rolled up on the roller rod 31 from bottom to top, and a water guide trough 6 is formed between the two roller rods 31 and the awning 32. The rolling direction of the awning 32 from bottom to top and the design of the water guide trough 6 enable rainwater to flow into the collection system more quickly and more concentratedly, thereby improving the collection efficiency of rainwater. The retention time of rainwater on the awning 32 is reduced, which reduces the possibility of water evaporation, thereby ensuring that more rainwater can be effectively utilized. The drainage design of the water guide trough 6 reduces the retention time of rainwater on the equipment, reduces the risk of equipment being damp and corroded, and extends the service life of the equipment. When rainfall occurs, rainwater first falls on the awning 32. Since the awning 32 is rolled up on the roller rod 31 from bottom to top, rainwater will flow along the water guide trough 6 to the diversion box 4 at the lower end and finally flow into the water tank 5 for collection. In this way, the awning 32 and the water guide trough 6 work together to achieve effective collection and discharge of rainwater.

[0034] More specifically, in order to ensure smooth water conduction in the water channel 6: the positioning rod 33 and the two roller rods 31 are arranged in a triangle so that the awning 32 is in a V shape. The design of the V-shaped awning 32 makes it easier for rainwater to flow along the water channel 6 into the guide box 4 at the lower end, thereby improving the water conduction efficiency. When it rains, the rainwater falls on the V-shaped awning 32. Since the cloth surface is in a V shape, the rainwater will naturally flow to the lower end along the inclined direction of the cloth surface. In the process of flowing to the lower end, the rainwater will gradually converge into a concentrated water flow, and naturally fall into the guide box 4, and finally flow into the water tank 5.

[0035] Specifically, in order to increase the service life of the tarpaulin 32: the tarpaulin 32 is a PVC coated cloth or a PU coated cloth. Both the PVC coated cloth and the PU coated cloth have excellent weather resistance, wear resistance and corrosion resistance, and can resist the erosion of wind, rain, sunlight and pollutants, thereby extending the service life of the tarpaulin 32. The PU coated cloth has better softness and elasticity, making it easier to fold, curl and install the tarpaulin 32, thereby improving the user experience.

[0036] Specifically, in order to facilitate the tarpaulin 32 to be always in a taut state: the end of the sliding sleeve 342 close to the roller rod 31 is fixedly connected with a spring shaft 3421, and the rotating shaft of the spring shaft 3421 is fixedly connected to the end of the roller rod 31. The design of the spring shaft 3421 ensures that the tarpaulin 32 is always in a taut state during the expansion or contraction process, thereby improving the rain-shielding effect and aesthetics. Since the tarpaulin 32 is always in a taut state, it can better resist the impact of wind and other external forces, thereby improving the stability of the entire rain-shielding structure 3. The taut tarpaulin 32 can reduce the wear and aging caused by relaxation, thereby extending the service life of the tarpaulin 32. When the expansion width of the tarpaulin 32 needs to be adjusted, the driving motor 344 is started and drives the driving rod 341 to rotate. Due to the threaded connection between the sliding sleeve 342 and the driving rod 341, the sliding sleeve 342 will move along the axial direction of the driving rod 341. At the same time, due to the fixed connection between the spring shaft 3421, the sliding sleeve 342 and the roller rod 31, the spring will be compressed or release energy. When the sliding sleeve 342 moves to the desired position, the spring will use the stored energy to keep the roller rod 31 and the tarpaulin 32 in a taut state. In this way, whether the tarpaulin 32 is unfolded or retracted, it can always remain flat and taut, ensuring the best rain-shielding effect.

[0037] Specifically, in order to facilitate the installation of the drive motor 344: a first installation groove 21 for installing the drive motor 344 is opened at one end of the installation frame plate 2, and the drive motor 344 is fixedly installed in the first installation groove 21 by bolts, and the output end of the drive motor 344 is fixedly connected to the end of the drive rod 341. The design of the first installation groove 21 makes the installation of the drive motor 344 simpler and faster. The user only needs to embed the drive motor 344 into the first installation groove 21 and fix it with bolts, without the need for complicated debugging and calibration. When adjusting the width of the tarpaulin 32, the drive motor 344 always maintains a stable and efficient operation state, ensuring the smooth expansion and contraction of the tarpaulin 32.

[0038] Furthermore, in order to facilitate the power supply to the drive motor 344: a battery 7 is arranged in the first mounting groove 21, and a photovoltaic panel 71 connected to the battery 7 is fixedly mounted on the mounting frame plate 2. By integrating the battery 7 and the photovoltaic panel 71, efficient use of solar energy can be achieved. Not only does it reduce the operating cost of the equipment, but it also reduces the dependence on traditional energy, which is in line with the green and sustainable development concept of modern society. The introduction of the battery 7 provides a stable power supply for the drive motor 344, ensuring the continuous and smooth operation of the equipment. When the photovoltaic panel 71 receives sunlight, it can convert solar energy into electrical energy and transmit the electrical energy to the battery 7 through wires for charging. When the battery 7 is fully charged, it will provide a stable power supply for the drive motor 344. When the user needs to adjust the unfolding width of the tarpaulin 32, the drive motor 344 will start and output rotational power, which will drive the drive rod 341 and the sliding sleeve 342 to move, thereby realizing the precise adjustment of the tarpaulin 32. During the whole process, the intelligent control system will monitor the power level of the battery 7 and the power generation efficiency of the photovoltaic panel 71 in real time, and automatically adjust the charging and discharging strategies as needed to ensure continuous power supply and stable operation of the equipment.

[0039] Specifically, the synchronous member 345 includes a synchronous gear 3451 fixedly mounted on the end of the driving rod 341 and a synchronous belt 3452 meshingly mounted on the two synchronous gears 3451. By adopting the combined design of the synchronous gear 3451 and the synchronous belt 3452, the two driving rods 341 can be operated synchronously. Not only the stability and reliability of the equipment are improved, but also the stability and consistency of the awning 32 during the expansion and contraction process are ensured. When the expansion width of the awning 32 needs to be adjusted, the driving motor 344 will start and output rotational power. This power is transmitted to the synchronous gear 3451 through the driving rod 341, causing it to start rotating. Due to the close meshing relationship between the synchronous gear 3451 and the synchronous belt 3452, when one of the synchronous gears 3451 rotates, it will drive the other synchronous gear 3451 to rotate together through the synchronous belt 3452. In this way, the two driving rods 341 can achieve synchronous operation. As the driving rod 341 rotates, the sliding sleeve 342 will move along its axial direction, thereby driving the roller rod 31 and the awning 32 to move together. In this way, the unfolded width of the awning 32 can be precisely adjusted.

[0040] More specifically, in order to facilitate the protection of the synchronous member 345: the other end of the mounting frame plate 2 is provided with a second mounting groove 22 for mounting the synchronous gear 3451 and the synchronous belt 3452. By providing a dedicated mounting and protection space for the synchronous member 345, the stability and reliability of the equipment are improved. This helps to ensure the stability and consistency of the awning 32 during the expansion and contraction process, thereby improving the overall performance of the simulated precipitation equipment. The design of the second mounting groove 22 helps to prevent dust, moisture and other impurities from damaging the synchronous member 345, thereby extending their service life. This reduces the maintenance cost of the equipment and improves the economy of the equipment. When the drive motor 344 is started and outputs rotational power, this power is transmitted to the synchronous gear 3451 through the drive rod 341. Since the synchronous gear 3451 is fixedly sleeved on the end of the drive rod 341 and embedded in the second mounting groove 22, they can rotate stably. At the same time, the synchronous belt 3452 is tightly engaged between the two synchronous gears 3451 and transmits as they rotate. In this way, the two drive rods 341 can achieve synchronous operation. As the driving rod 341 rotates, the sliding sleeve 342 moves along its axial direction, thereby driving the roller rod 31 and the awning 32 to move together. In this way, the unfolded width of the awning 32 can be accurately adjusted. In the whole process, the second mounting groove 22 provides necessary protection and support for the synchronizer 345, ensuring the stable operation of the equipment.

[0041] Specifically, in order to facilitate the drainage of the water in the diversion box 4 to the inside of the water tank 5, a drain port 41 is provided at the lower end of the diversion box 4, and a diversion pipe 8 is plugged into the inside of the drain port 41, and the bottom of the diversion pipe 8 is plugged into the top of the water tank 5. By providing the drain port 41 and designing the plug-in method of the diversion pipe 8, the drainage efficiency of the simulated precipitation device is improved. It helps to ensure that the water inside the diversion box 4 can be discharged in time and smoothly, thereby avoiding the problems of water accumulation and leakage. When the simulated precipitation device starts to work, the diversion box 4 will collect a certain amount of water. As the water accumulates, the water will flow into the diversion pipe 8 through the drain port 41. Since one end of the diversion pipe 8 is tightly plugged into the inside of the drain port 41 and the other end is plugged into the top of the water tank 5, the water will flow smoothly into the inside of the water tank 5 through the diversion pipe 8. The purpose of draining the water in the diversion box 4 to the inside of the water tank 5 is achieved. In the whole process, the close cooperation between the drain port 41 and the diversion pipe 8 ensures the smooth flow of water and prevents the occurrence of leakage.
