Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Reference Figures 1-4 As shown, the present invention provides a liftable soil and water loss measuring device for forest understory and slopes, including a water supply mechanism, which is connected to two rainfall mechanisms. A lifting mechanism is installed at the bottom of the rainfall mechanism. The lifting mechanism includes an outer rod 13, an inner rod 12 is slidably connected to the top of the outer rod 13, a leveling part is fixed to the outer side of one of the outer rods 13, the rainfall mechanism is installed at the top of the inner rod 12, a lifting part is provided between the outer rod 13 and the inner rod 12, and a stabilizing mechanism is rotatably connected to the bottom of the outer rod 13.

[0024] The water supply mechanism provides water to both rainfall mechanisms simultaneously. The outer rod 13 and the inner rod 12 are slidably connected to adjust the height of the rainfall mechanism so as to achieve the required rainfall height. The stabilizing mechanism set at the bottom of the outer rod 13 is used to adapt the lifting mechanism to the outdoor slope environment and make the lifting mechanism more stable during use. At the same time, the leveling part is used to put the two rainfall mechanisms at the same horizontal position so that the two rainfall mechanisms can simulate the same rainfall environment.

[0025] The design is further optimized so that the lifting part includes lifting pulleys 11 symmetrically fixed to the top surface of the outer rod 13. A lifting steel cable 9 is installed inside the lifting pulley 11. The lifting steel cable 9 is located between the outer rod 13 and the inner rod 12. A handle 10 is provided on the outside of the lifting steel cable 9. The handle 10 is located on the outside of the outer rod 13.

[0026] Two pulleys are used to save effort, reduce friction and wire rope wear, one wire rope is used to control the raising and lowering of the inner rod 12, and two handles 10 are used to better pull the wire rope to control the raising and lowering of the inner rod 12.

[0027] To further optimize the design, the side wall of the outer rod 13 is provided with multiple fixing holes 7 at equal intervals, and a fixing spring 6 is provided in the fixing hole 7.

[0028] The scheme is further optimized. The leveling part includes a laser emitter 15 fixed to the outside of one of the outer rods 13, and a scale line 14 is provided on the outside of the other outer rod 13.

[0029] To further optimize the design, a level bubble 5 is provided on the outer side of the outer rod 13.

[0030] The fixing hole 7 has an opening every 5cm, which, together with the fixing spring 6, controls the height. The height difference is confirmed using the scale line 14 on one side of the device and the laser emitter 15 on the other side. Pulling the handle 10 downwards causes the lifting cable 9 to move the inner rod 12 upwards, adjusting the height of the rain machines on both sides. The lifting cable 9, handle 10, and lifting pulley 11 together control the height of the entire device. Drilling holes in the walls of the inner and outer rods 13 allows for more precise height control. The fixing spring 6 passes through the fixing inner rod 12. Simultaneously, the lifting mechanism can lower the device to a height suitable for changing the nozzle 23, making field experiments safer.

[0031] Further optimization of the scheme: the stabilizing mechanism includes a universal ball 4 rotatably connected to the bottom surface of the outer rod 13, a movable base plate 3 installed on the bottom surface of the universal ball 4, and multiple fixed legs 1 rotatably connected at equal intervals on the outer side of the bottom of the outer rod 13, with telescopic fixing screws 2 provided on the fixed legs 1.

[0032] The stabilizing mechanism ensures the stability of the entire device during operation, thus mitigating the impact of external interference factors such as shaking on the experimental results.

[0033] The device is equipped with a movable base plate 3 and a retractable fixed stand 1, which allows for rainfall experiments on slopes. Because the device occupies a small area and its height is controllable, experiments can be conducted under forest cover, allowing for better measurement of soil and water loss data under forest cover and on slopes.

[0034] The fixed bracket 1 serves to stabilize the device on the slope. The vertically movable inner rod 12 and outer rod 13 allow for better adjustment of the support structure on non-planar surfaces, enhancing stability. The telescopic fixing screw 2 secures the fixed bracket 1 to the desired length, preventing further extension or reduction. The movable base plate 3 allows for better use on slopes, conforming to the ground to determine the lifting height. The omnidirectional ball joint 4 allows for more flexible twisting of the movable base plate 3. The bubble level 5 ensures the device is vertical, enabling better control and adjustment, and reducing errors. The fixed bracket 1 can be installed when needed and retracted when not in use.

[0035] The scheme is further optimized. The water supply mechanism includes a water supply tank 16, which is connected to a water pump 17. The output end of the water pump 17 is connected to a first quick-connect group 18. The end of the first quick-connect group 18 away from the water pump 17 is connected to a tee 19. Both sides of the tee 19 are connected to rainfall mechanisms.

[0036] The scheme is further optimized. The rain-making mechanism includes a high-pressure water pipe 20 connected to the tee 19. The end of the high-pressure water pipe 20 away from the tee 19 is connected to an elbow 21. The end of the elbow 21 away from the high-pressure water pipe 20 is connected to a rain-making pipe 22. The end of the rain-making pipe 22 away from the elbow 21 is connected to a second quick-connect group 24. The second quick-connect group 24 is connected to a nozzle 23.

[0037] The design is further optimized so that a water pipe fixing seat 8 is symmetrically fixed to the top surface of the inner rod 12, and a rain pipe 22 is installed inside the water pipe fixing seat 8.

[0038] The scheme is further optimized by installing a pressure regulating component inside the high-pressure water pipe 20. The pressure regulating component includes two E-type connectors 25 that are connected to the high-pressure water pipe 20. A pressure gauge 26 is installed between the two E-type connectors 25. A pressure regulating valve 27 is installed between the pressure gauge 26 and one of the E-type connectors 25.

[0039] The rain-generating mechanism is fixed to the inner rod 12 via the water pipe fixing seat 8. The rain-generating mechanism supplies water through the water supply tank 16, the water pump 17 acts as a pressurizer, the first quick-connect assembly 18 facilitates disassembly, allowing the water supply mechanism to be disassembled for easy carrying and transportation, the pressure regulating valve 27 and the pressure gauge 26 control the water pressure, enabling real-time monitoring of the water pressure to reach the required level, and the second quick-connect assembly 24 facilitates quick replacement of the nozzle 23, allowing for easy replacement of the nozzle 23 with the required flow rate.

[0040] The rainfall simulation system uses dynamic simulation technology to study the mechanism of soil erosion caused by rainfall. Equipped with multiple detachable nozzles 23, it can quickly adjust the rainfall intensity and has three rainfall intensities: light rain, moderate rain, and heavy rain. This solves the uncontrollability of natural rainfall, facilitates the collection of soil erosion data, and reduces the difficulty of field data collection.

[0041] Because of the valves installed, the intensity of rainfall can be better controlled, water resources can be used more effectively, and the goal of saving and rationally utilizing water resources can be achieved.
