Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, specifically a runoff flume for analyzing soil erosion driving factors. Background Technology

[0002] Soil runoff flumes are important devices for studying soil runoff characteristics, playing a crucial role in the study of runoff generation mechanisms under heavy and continuous rainfall conditions. They primarily analyze the runoff generation mechanisms and processes in small watersheds in mountainous areas by collecting runoff data under different rainfall conditions, which is of great significance for improving mountain flood disaster prevention technologies.

[0003] Current methods for analyzing soil erosion drivers typically employ integrated, fixed tank structures. These structures are bulky and inconvenient to move and transport. Furthermore, the shared collection tank structure across multiple tanks necessitates individual tank spraying during experiments, making the process cumbersome and impacting experimental efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a runoff flume for analyzing soil erosion driving factors, in order to solve the problems mentioned in the background art. Currently, the analysis of soil erosion driving factors uses an integrated fixed flume frame structure, which makes the flume large and inconvenient to move and transport. In addition, the fact that multiple flumes share the same collection tank structure means that each flume needs to be rained on individually during the experiment, which is cumbersome and affects the efficiency of the experiment.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A runoff channel for analyzing soil erosion driving factors includes a supporting base plate. The bottom surface of the supporting base plate is symmetrically fitted with casters.

Bottom screw holes are symmetrically opened on the bottom surface of the supporting base plate, and the top surfaces of the casters are fixedly connected to… The support base plate has a connecting screw, and the top surface of the support base plate has symmetrically opened top screw holes. The top surface of the support base plate has evenly opened mounting screw holes. The bottom end of the fixed top rod is fixedly connected to the bottom screw. The bottom ends of the support upright and the adjusting cylinder are fixedly connected to the mounting screw. The bottom surface of the support top box has symmetrically opened bottom mating grooves. A connecting shaft is inserted into the inner side of the bottom mating groove. A multi-hole base plate is horizontally fixedly snapped onto the inner bottom surface of one of the support top boxes. A locking groove is vertically opened on the inner side of the support top box. A locking side frame is fixedly installed on the outer side of the sealing plate.

[0007] In a preferred embodiment of this utility model: there are four movable wheels, and each of the four movable wheels is provided with a brake plate structure on its side. The top surfaces of the four movable wheels are respectively connected to the bottom opening end of the bottom screw hole. There are four fixed top rods, and the four fixed top rods are arranged in parallel with each other. The fixed top rods are all set with two long and two short dimensions, and the bottom ends of the fixed top rods are connected to the top opening end of the top screw hole.

[0008] In a preferred embodiment of this utility model, there are two guide groove rods, and one end of the top channel of the two guide groove rods is open. The guide groove rods are obliquely fixedly connected to the top of the two sets of fixed top rods. The support rods are arranged in parallel with each other, and the top of the two support rods are inserted into the inner side of the bottom mating groove.

[0009] In a preferred embodiment of this utility model: there are two supporting top boxes, and the two supporting top boxes are arranged in parallel with each other. The top surface groove opening end of the two supporting top boxes is located near one end of the top surface of the guide groove rod. The sealing plate is vertically snapped into the inner side of the top groove opening end of the supporting top box. The bottom ends of the two adjusting cylinders are connected to the top opening end of the mounting screw hole.

[0010] In a preferred embodiment of this utility model: the bottom screw holes are symmetrically opened on the bottom surface of the supporting base plate near the four corners. The top end of the connecting screw is threadedly fixedly connected to the inner side of the bottom screw hole. The top screw hole and the mounting screw hole are all correspondingly opened on the top surface of the supporting base plate near the four corners. The bottom end of the bottom screw is threadedly fixedly connected to the inner side of the top screw hole. The bottom end of the mounting screw is threadedly fixedly connected to the inner side of the mounting screw hole. The bottom mating groove is symmetrically opened on the bottom surface of the supporting top box near both ends of the center line.

[0011] In a preferred embodiment of this utility model: the connecting shafts are horizontally inserted into the output end through hole of the adjusting cylinder and the top side through hole of the support rod. The locking groove is vertically opened in the groove of the support top box near the opening end, and the top of the locking groove is open.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention involves fixing the top rod and the supporting top box to the top surface of the supporting base plate using screws at the bottom. Soil is then filled into the supporting top box. A sealing plate of the appropriate size is vertically engaged at the opening of the inner channel of the supporting top box. The sealing plate, secured by a side frame, seals the channel opening, allowing the soil to be filled to a specified thickness. By controlling the extension and retraction of the adjusting cylinder at the bottom, the output end presses against one end of the supporting top box, causing it to rotate upwards. Connected by a shaft, one end of the supporting top box rotates with the top of the supporting rod, allowing the supporting top box to be adjusted and rotated to a specified position. The angle is adjusted to create a specified slope effect for the internal soil. During a uniform simulated rain operation at the top, water falls downwards onto the soil inside the supporting top box. One type of soil has a perforated bottom plate for permeable soil effect, while the other has no perforated plate structure for non-permeable soil effect. After the rainwater flows along the adjusted slope, it carries the soil downwards into the top channel of the guide rod at one end. The tilt of the guide rod collects and records the lost soil, thus achieving the effect of analysis experiment. The modular design makes the whole unit compact after disassembly, facilitating transportation and packaging. At the same time, the automated adjustable angle structure can meet the needs of diverse adjustment experiments. Attached Figure Description
