Description

Technical Field

[0001] This invention relates to a circulating water device that combines the absorption of supernatant and the transfer of sediment, suitable for experiments studying soil water erosion under artificial rainfall conditions. Background Technology

[0002] In experiments studying soil water erosion under artificial rainfall conditions, removing the supernatant from the settled water sample while retaining the sediment, and transferring the sediment to a sediment collection device while simultaneously drying it in an oven, is an essential step. Current methods for removing the supernatant primarily involve either natural sedimentation followed by manual pouring or pumping. Manual pouring can easily disturb the lower sediment layer, causing it to mix with the supernatant and be poured out again, leading to significant experimental errors. When using a pump to extract the supernatant, the pump position needs constant adjustment, and determining the extraction point becomes extremely difficult when approaching the sediment layer, making the process cumbersome and laborious. Meanwhile, after removing the supernatant, the remaining sediment needs to be transferred. The existing method involves manually tilting the water sample collection bucket so that its wall fits against the sediment collection device, while squeezing a plastic bottle filled with supernatant and with a punctured cap to flush the sediment in the water sample collection bucket, allowing it to flow into the sediment collection device. This process is very cumbersome, and due to human factors, the tilt angle of the runoff collection bucket is inevitably unreasonable during the transfer process, resulting in incomplete collection of sediment and causing experimental errors.

[0003] Chinese Patent Publication No. CN 210571560 U discloses a device capable of accurately and fully extracting supernatant. This technology uses a buoyancy block to automatically adjust the extraction position; simultaneously, a rigid suction pipe with a horizontally oriented opening ensures that disturbances generated during extraction do not affect the next water layer. However, its shortcomings include: it cannot be used by multiple researchers simultaneously, thus its work efficiency needs improvement. Furthermore, it cannot complete the subsequent operation of transferring sediment to a sediment collection device. Summary of the Invention

[0014] Compared with the prior art, the technical effects and advantages of the present invention are as follows:

[0015] This circulating water device, which combines the absorption of supernatant and the transfer of sediment, benefits from the design of the fixed frame, which can simultaneously fix multiple runoff collection tanks. Combined with the vertically moving suction assembly, it achieves simultaneous absorption of supernatant from multiple collection tanks. Thanks to the design of the vertically moving suction assembly, the right-angle fixed bracket ensures that the suspended suction disc is always fixed directly above the runoff collection tank, allowing for vertical movement by gripping the rubber handle, thus absorbing the supernatant from the runoff collection tanks. The support rod design, with the fixed frame driven by a rotating shaft, restricts the rotation angle, thereby facilitating the collection of sediment. The double-sided connection design of the collection tank enables the reuse of the clarified liquid, saving water resources. This circulating water device, which combines the absorption of supernatant and the transfer of sediment, not only absorbs supernatant but also transfers sediment, while simultaneously recycling the clarified liquid.

[0029] Preferably, the vertically movable liquid absorption assembly 7 includes a suspended liquid absorption disc 71, a right-angle fixing bracket 72, a water absorption hose 73, a water absorption thin straight tube 74, an airbag 75, and a grip rubber 76; the water absorption hose 73 is embedded in the right-angle fixing bracket 72, the right-angle fixing bracket 72 is connected and fixed to the fixing plate 5, one end of the water absorption hose 73 is connected to the liquid collection tank 2, and the other end is slidably sleeved with the water absorption thin straight tube 74, the radius of the water absorption thin straight tube 74 is smaller than that of the water absorption hose 73 and its lower part is connected to the suspended liquid absorption disc 71.

[0030] Preferably, the grip rubber 76 is sleeved on the outside of the water-absorbing hose 73 near the suspended liquid-absorbing disc 71.

[0031] Preferably, the upper layer of the suspended liquid-absorbing disc 71 is provided with four mutually perpendicular and interconnected water-absorbing channels 711, and each water-absorbing channel 711 is provided with a filter screen 712.

[0032] Preferably, the airbag 75 is positioned one-third above the water-absorbing hose 73.

[0033] Preferably, the tilting device 6 includes a runoff collection bucket 61, a fixed frame 62, a rotating shaft 63, and a rotating shaft fixing rod 64; the rotating shaft 63 is fixed to the left and right ends of the collection tank 2 through the rotating shaft fixing rod 64; the fixed frame 62 is rotatably connected to the collection tank 2 through the rotating shaft 63; multiple runoff collection buckets 61 are fixed inside the fixed frame 62; after the fixed frame 62 is rotated and tilted under the action of the rotating shaft 63, the fixed frame 62 is connected to the support rod 31, and the edge of the opening of the runoff collection bucket 61 is connected to the sediment collection box 33.

[0034] This circulating water device, which combines the absorption of supernatant and the transfer of sediment, is used by placing the runoff collection bucket 61 to be treated in the fixed frame 62 to limit and fix the runoff collection bucket 61, and waiting for the solution in the runoff collection bucket 61 to settle and separate into layers, with the supernatant on the upper layer and the soil sediment on the lower layer. At the same time, the sediment collection box 33 is placed in the circular groove 361 on the sliding push-pull device 36 to limit and fix the sediment collection box 33.

[0035] After preparation, the experimenter first uses the rubber 76 to pull the water suction hose 73 vertically downward under the action of the right-angle fixed bracket 72, so that the suspended liquid suction disc 71 enters the supernatant in the runoff collection bucket 61. Due to the suspension property of the suspended liquid suction disc 71, it can be completely suspended in the supernatant. At this time, due to the buoyancy of the solution, the water suction thin straight tube 74 enters the water suction hose 73.

[0036] Then, the supernatant is drawn up. Since the suction channel 711 is horizontal, disturbance to the lower water layer is avoided during the suction process. The experimenter gently squeezes the air bag 75 with one hand to expel the air, and then quickly releases the air bag 75, allowing the supernatant absorbed by the suction channel 711 to flow into the collection tank 2 through the suction tube 74 and the inlet hose 73. As the suction process progresses, part of the suction tube 74 that enters the suction hose 73 automatically descends as the supernatant level decreases. The supernatant suction process ends when the lower layer of the suspended suction disc 71 contacts the surface of the sediment. The suction process for the remaining runoff collection tank 61 is repeated.

[0037] It is worth noting that since the water suction channel 711 is always immersed in the supernatant layer and is oriented horizontally, the disturbance generated during water suction will not affect the next water layer, so the entire suction process will not disturb the sediment layer. At the same time, since sediment particles inevitably float in the supernatant, a filter screen 712 is installed at the inlet of each water suction channel 711 to prevent sediment particles from being sucked into the collection tank 2. Furthermore, as the supernatant is sucked in, the water level in the collection tank 2 will gradually rise. When it reaches a certain height, it will inevitably affect the suction of the supernatant. Therefore, the experimenter needs to observe the water level through the internal transparent plastic 22 on one side of the collection tank 2. If it reaches a certain position, drainage must be carried out through the outlet 23.

[0038] After the supernatant in all the runoff collection buckets 61 has been completely absorbed, the experimenter applies the inlet hose 73 to restore the suspended liquid absorption disc 71 to its initial height. Then, the experimenter applies the pull rod of the fixing frame 62, causing the fixing frame 62 to rotate under the action of the rotating shaft 63, so that the fixing frame 62 connects with the support rod 31. At this time, the edge of the opening of the runoff collection bucket 61 is connected to the sediment collection box 33. The water pump 35 is turned on, and water is sprayed out from the nozzle 32 through the collection tank 2. The water washes the sediment in the runoff collection bucket 61. Under the action of gravity along the inner wall of the bucket, the water carries the sediment into the sediment collection box 33. After the sediment has been completely transferred into the sediment collection box 33, the water pump 35 is turned off. The transfer process of sediment in the remaining runoff collection buckets 61 can be repeated.

[0039] Finally, after completing the transfer of sediment in the runoff collection bucket 61, the fixed frame 62 is restored to the state of suction of supernatant. Then, the sliding push-pull device 36 is pulled out by the action of the two trapezoidal grooves 211 of the liquid collection tank cover plate 21 matching the track of the sliding push-pull device 36. At this time, the sediment collection box 33 can be removed for subsequent operations.
