Abstract
Description
Technical Field
[0001] This utility model relates to the field of rainfall testing technology, and in particular to a simulated rainfall device. Background Technology
[0002] Modern artificial rainfall simulation devices, through precise fluid control systems and intelligent regulation technologies, have achieved a high degree of realism in replicating the natural rainfall environment of small-scale agricultural experimental fields. The core function of these devices is to accurately reproduce different rainfall scenarios, providing a controllable and repeatable testing environment for agricultural research, soil and water conservation research, and irrigation technology verification.
[0003] Compared to traditional natural observation methods, simulation devices can acquire rainfall response data in hours that would take weeks or even months to accumulate using traditional methods, greatly accelerating the development of agricultural technology. However, existing simulated rainfall devices suffer from significant inconvenience in adjusting the width of rainfall coverage, as this adjustment largely relies on manual operation.
[0004] The nozzle array supports or rainfall units of the device are mostly fixed modular structures, requiring manual disassembly, assembly, or physical extension of the supports to change the rainfall coverage width. This makes it impossible to achieve automatic adaptation based on the actual width requirements of the experimental field. The adjustment process is not only time-consuming and labor-intensive, but also difficult to accurately match the width differences of different small-scale agricultural experimental fields. When frequently changing experimental areas or adjusting the coverage range, human error can easily affect the uniformity of rainfall, reducing the device's flexibility in diverse width scenarios. Utility Model Content

Detailed Implementation
[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0017] Example like Figures 1-5 As shown, a simulated rainfall device includes a support assembly 1, a spray assembly 2, and an adjustment assembly 3. The support assembly 1 includes a support frame 11, a connecting frame 13 fixed to the right side of the support frame 11, a spray assembly 2 disposed on the right side of the connecting frame 13, and an adjustment assembly 3 disposed on the upper end of the spray assembly 2. The spray assembly 2 includes a first base 21, a first water supply pipe 23 fixed to the upper end of the first base 21, the upper end of the first water supply pipe 23 fixed to the connecting frame 13, the lower end of the first water supply pipe 23 fixed to the first base 21, and a second base 22 movably mounted on both ends of the first base 21. The adjustment assembly 3 includes a sliding plate 31 and a pulley assembly 32, a second water supply pipe 24 fixed to the upper end of the second base 22, a sliding plate 31 fixed to the side of the second water supply pipe 24, pulley assemblies 32 mounted on the sides of both ends of the first water supply pipe 23, and hydraulic rods 33 connected to the upper end of the second water supply pipe 24. The other ends of the two hydraulic rods 33 are fixed to the first water supply pipe 23.
[0018] During use, the extension and retraction are achieved through hydraulic drive: when the hydraulic rod 33 extends, it pushes the second water supply pipe 24 to move outward; when the hydraulic rod 33 retracts, it pulls the second water supply pipe 24 to move inward. As the second water supply pipe 24 moves under the drive of the hydraulic rod 33, the slide plate 31 rolls along the pulley block 32, and the two work together to form a low-friction guiding structure. No manual operation is required; the width adjustment is directly powered, replacing traditional manual disassembly, assembly, or manual extension and retraction methods, thus automating the adjustment process.
[0019] like Figures 1-4 As shown, lifting legs 12 are installed on the lower sides of both ends of the support frame 11, and a fixed crank 121 is installed on the upper end of the lifting legs 12. The lifting legs 12, with their own telescopic structural characteristics, can directly change the overall height of the support frame 11 above the ground, thereby flexibly adapting to the differences in terrain elevation in the experimental field and meeting the specific height requirements of different simulated rainfall experiments. When the height is adjusted to the required position, the fixed crank 121 can securely lock the current state of the lifting legs 12. The specific fixing method is as follows: the fixed crank 121 is connected to the support frame 11 through threads. When the fixed crank 121 is rotated, the fixed crank 121 can abut against the lifting legs 12, fixing the lifting legs 12 and the support frame 11.
[0020] like Figures 1-4 As shown, multiple sets of spray heads 5 are installed at the lower ends of the first water supply pipe 23 and the second water supply pipe 24. The spray heads 5 can convert the water flow delivered by the water supply pipe into water droplets or water flow patterns that simulate natural rainfall through specific structures such as atomizing holes and spray nozzles, and spray them evenly onto the test area below.
[0021] like Figures 1-4 As shown, the first water supply pipe 23 and the second water supply pipe 24 are equipped with water inlets 6. The water inlets 6 stably introduce external water sources into the first water supply pipe 23 and the second water supply pipe 24 through pipes or joints, providing a continuous water supply for the entire sprinkler system.
[0022] like Figures 1-4As shown, the first water supply pipe 23 and the second water supply pipe 24 are not at the same horizontal position. The first base 21 and the second base 22 are provided with transverse sliding grooves 7, which are staggered. These grooves are key guiding and limiting structures to prevent the spray heads 5 from moving and colliding with each other, as the first water supply pipe 23 and the second water supply pipe 24 are not at the same horizontal position. Specifically, the transverse sliding groove 7 on the first base 21 is used to avoid the spray heads 5 on the bottom side of the second water supply pipe 24, and the transverse sliding groove 7 on the second base 22 is used to avoid the spray heads 5 on the bottom side of the first water supply pipe 23. Water baffles 4 are installed on both sides of the lower end of the first base 21 and the second base 22. The water baffles 4 physically block and guide the water flow sprayed from the spray heads 5. By forming a barrier on both sides of the base, the splash angle and diffusion range of the water droplets can be effectively limited.
[0023] When using the simulated rainfall device, first turn the fixed crank 121 at the upper end of the lifting support 12 to adjust the extension length of the lifting support 12. Then, connect the external water source through the inlet 6 on the first water supply pipe 23 and the second water supply pipe 24 via pipes or adapters. According to the width requirements of the test area, the hydraulic rod 33 in the adjustment component 3 is activated: if the test area is wide, the hydraulic rod 33 is extended to push the second water supply pipe 24 to move outward. At this time, the second base 22 slides along the transverse groove 7 on the first base 21 with the second water supply pipe 24. At the same time, the sliding plate 31 on the side of the second water supply pipe 24 rolls along the pulley group 32 at both ends of the first water supply pipe 23. The low-friction guide structure helps to achieve smooth movement until the second base 22 on both sides extends to a suitable length so that the overall spray width covers the test area. If the test area is narrow, the hydraulic rod 33 is retracted to pull the second water supply pipe 24 to move inward. Similarly, the retraction action is completed by the cooperation of the sliding plate 31 and the pulley group 32. The transverse groove 7 can effectively avoid the problem of the spray head 5 colliding due to the first water supply pipe 23 and the second water supply pipe 24 not being in the same horizontal position. The baffle plate 4 physically blocks and guides the water flow sprayed from the spray head 5. By forming a barrier on both sides of the base, it can effectively limit the splash angle and diffusion range of water droplets.
[0024] This is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
