Description

Technical Field

[0001] This utility model belongs to the field of soil and water loss detection equipment, and in particular relates to a sediment separation mechanism for runoff monitoring. Background Technology

[0002] Soil and water conservation monitoring is a key support for the prevention and control of human-caused soil erosion and the strong supervision of soil and water conservation. As a core indicator for measuring the degree of soil erosion and sediment deposition, accurate and efficient monitoring of sediment content is crucial. Currently, runoff plots remain the mainstream facility for obtaining this indicator. However, in the core step of sediment content determination, namely the separation and quantification of sediment in runoff samples, traditional manual methods are still widely relied upon.

[0003] In existing technologies, sediment separation typically follows a cumbersome manual process, either in the laboratory or on-site: surveyors must manually stir the collected runoff samples to homogenize them, then take samples, filter them through filter paper, dry them in an oven for an extended period, and weigh them using a balance before finally calculating the sediment content. The core drawback of this method lies in the sediment separation process itself: low separation efficiency, time-consuming drying, cumbersome procedures heavily reliant on skilled personnel, and numerous manual interventions that can introduce errors during stirring, filtering, and transfer, affecting the accuracy and consistency of the data. This results in high human resource consumption for existing monitoring methods, making it difficult to meet the demands of high-frequency, real-time monitoring. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a sediment separation mechanism for runoff monitoring, which solves the problems of large sampling errors and cumbersome sediment separation steps in the prior art.

[0005] To achieve the above and other related objectives, this utility model provides a sediment separation mechanism for runoff monitoring, including a separation tank body, a sediment separation component and a water storage and drainage component disposed inside the separation tank body; The top of the separation tank body is connected to a water inlet pipe, which is connected to a runoff detection port; the bottom of the separation tank body is provided with a drain hole. The sediment separation assembly includes a first sediment separator and a second sediment separator arranged in a stacked manner, and both the first sediment separator and the second sediment separator have through holes in the middle. The water storage and drainage assembly includes a lifting member, a connecting slide rod, and a sealing member that are threaded together from top to bottom; the connecting slide rod is used in conjunction with a through hole, and a float is fixedly connected to the side of the connecting slide rod near the sealing member; the sealing member is used in conjunction with a drainage hole.

[0006] Optionally, the separation tank body includes a separation tank body and a separation tank lid, and the separation tank body and the separation tank lid are fixed by threads.

[0007] Optionally, a diversion component is provided on the top inner side of the lid of the separation bucket, and the diversion component has an umbrella-shaped structure.

[0008] Optionally, the outer side of the lid of the separation bucket is provided with a rotating handle.

[0009] Optionally, the side wall of the separation tank is provided with an inwardly extending limiting protrusion, which is an annular protrusion.

[0010] Optionally, the outer side of the separating barrel is provided with a lifting handle.

[0011] Optionally, the drain hole is connected to a drain pipe, and the drain pipe is equipped with a switch and a flow meter.

[0012] Optionally, a connecting sleeve is provided between the first sediment separator and the second sediment separator, and the connecting sleeve is coaxially sleeved on the outside of the connecting slide rod.

[0013] Optionally, the first sediment separator has a disc-shaped structure and a first annular groove.

[0014] Optionally, the second sediment separator has a disc-shaped structure and a second annular groove.

[0015] As described above, the sediment separation mechanism for runoff monitoring of this invention has at least the following beneficial effects: This invention utilizes a double-layered sediment separation assembly to achieve graded and efficient separation: the stacked first and second sediment separators, employing different apertures or structures, can progressively intercept and classify sediment of different particle sizes (such as coarse and fine sand), facilitating detailed sediment source analysis; and a water storage and drainage assembly enables "small-scale storage, large-scale self-drainage": when rainfall and total runoff are low, the sealing element of the water storage and drainage assembly, under gravity, seals the drainage hole, allowing the device to function as a water storage tank. When rainfall and total runoff are high, the water level inside the separation tank rises, and the increased buoyancy lifts the float, moving the sealing element away from the drainage hole, automatically opening the drainage to prevent overflow and monitoring interruption. The threaded lifting element, connecting slide rod, and sealing element constitute a reliable transmission mechanism.

[0016] This utility model separates the main body of the separation tank into a tank body and a lid, and uses threads to fix the tank body and lid for easy opening and closing. This facilitates the subsequent removal of the internal double-layer mud and sand separation components for weighing, cleaning, or replacement of mud and sand, greatly simplifying field maintenance work. The rotating handle on the lid and the lifting handle on the tank body facilitate the installation, transportation, and opening of the device. The switch on the drain pipe can be closed during non-use periods (such as during transportation or replacement) to prevent residual liquid leakage.

[0017] This invention provides reliable installation and positioning for the internal separation components through an annular limiting protrusion within the separation tank, preventing displacement during operation. A connecting sleeve between the first and second sediment separators adjusts the distance between them to accommodate separation tank bodies of varying heights. Furthermore, by creating a first annular groove on the first sediment separator and a second annular groove on the second sediment separator, the captured sediment is temporarily stored without significantly increasing water flow resistance, preventing the separated sediment from being stirred up by subsequent water flow and ensuring continuous and stable separation efficiency.

[0018] This invention uses an umbrella-shaped diverter inside the barrel lid to circumferentially disperse the water flow injected from the inlet pipe onto the first sediment separator, preventing the water flow from directly and continuously impacting the first sediment separator and causing local sediment accumulation, thus improving separation efficiency. The flow meter connected to the drain pipe can directly measure the volume of the discharged water flow, improving the integrity and reliability of the data. Attached Figure Description

Therefore, they have no substantial technical significance.

[0023] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0024] Please see Figures 1 to 5This utility model provides a sediment separation mechanism for runoff monitoring, including a separation tank body 1, a sediment separation component 2 and a water storage and drainage component 3 disposed inside the separation tank body 1; the top of the separation tank body 1 is connected to a water inlet pipe 4, which communicates with a runoff detection port; a drainage hole is provided at the bottom of the separation tank body 1; the sediment separation component 2 includes a first sediment separator 201 and a second sediment separator 202 stacked together (here, the first sediment separator 201 and the second sediment separator 202 can be selected with different pore sizes of filter screens according to actual conditions, such as the filter screen pore size of the first sediment separator 201 being 0.5mm and the filter screen pore size of the second sediment separator 201 being 0.25mm, and the specific pore size of the filter screen is not limited here), and the middle of the first sediment separator 201 and the second sediment separator 202 are both The device has a through hole; the water storage and drainage assembly 3 includes a lifting member 301, a connecting slide rod 302, and a sealing member 303 connected sequentially from top to bottom by threads; the connecting slide rod 302 is used in conjunction with the through hole, and a float 8 is fixedly connected to the side of the connecting slide rod 302 near the sealing member 303; the sealing member 303 is used in conjunction with the drainage hole. This application achieves graded and efficient separation through a double-layer arrangement of sediment separation assembly 2: the stacked first sediment separator 201 and the second sediment separator 202 can use different apertures or structures to achieve step-by-step interception and classification of sediment of different particle sizes (such as coarse sand and fine sand), which helps in the detailed analysis of sediment sources; the water storage and drainage assembly 3 achieves "small flow storage, large flow self-drainage": when the rainfall is small and the total runoff is small, the sealing member 303 of the water storage and drainage assembly 3 is pressed tightly against and closed by gravity, so that the device can be used as a water storage tank. When the rainfall and total runoff are large, the water level inside the main body 1 of the separation tank rises. The increased buoyancy will lift the float 8 and move the seal 303 away from the drain hole, automatically opening the drain to prevent overflow from causing monitoring interruption. The threaded lifting part 301, the connecting slide rod 302 and the seal 303 constitute a reliable transmission mechanism.

[0025] In this embodiment, please refer to Figures 1 to 5The separating tank body 1 includes a separating tank body 101 and a separating tank lid 102, which are threaded together. A rotating handle 6 is provided on the outer side of the separating tank lid 102, and a lifting handle 7 is provided on the outer side of the separating tank body 101. A drain pipe is connected to the drain hole, and a switch and a flow meter are provided on the drain pipe. This application separates the separating tank body 1 into a separating tank body 101 and a separating tank lid 102, and then threadedly fixes the separating tank body 101 and the separating tank lid 102 together. 2. It is easy to open and close, which facilitates the subsequent removal of the internal double-layer sediment separation component 2 for sediment weighing, cleaning or replacement, greatly simplifying field maintenance work. The rotating handle 6 on the separation barrel lid 102 and the lifting handle 7 on the separation barrel body 101 facilitate the installation, transportation and opening of the separation device. The switch on the drain pipe can be closed during non-use periods (such as during transportation or replacement) to prevent residual liquid leakage. The flow meter connected to the drain pipe can directly measure the volume of the discharged water flow, improving the integrity and reliability of the data.

[0026] In this embodiment, please refer to Figures 1 to 5 A diverter 5 is provided on the inner side of the top of the separation tank cover 102. The diverter 5 has an umbrella-shaped structure. In this application, the umbrella-shaped diverter 5 on the inner side of the separation tank cover 102 can circumferentially disperse the water flow injected by the water inlet pipe 4 onto the first sediment separator 201, avoiding the water flow from directly and continuously impacting the first sediment separator 201 and forming local sediment accumulation, thereby improving the separation efficiency.

[0027] In this embodiment, the side wall of the separation tank is provided with an inwardly extending limiting protrusion, which is an annular protrusion. A connecting sleeve 203 is provided between the first sediment separator 201 and the second sediment separator 202. The connecting sleeve is coaxially sleeved on the outside of the connecting slide rod 302. The first sediment separator 201 has a disc-shaped structure and a first annular groove. The second sediment separator 202 has a disc-shaped structure and a second annular groove. This application uses the annular limiting protrusion inside the separation tank to form an internal separation group. The components provide reliable installation positioning to prevent displacement during operation; by adding a connecting sleeve 203 between the first sediment separator 201 and the second sediment separator 202, the distance between the first sediment separator 201 and the second sediment separator 202 can be adjusted to accommodate the separation tank body 1 of different heights; by opening a first annular groove on the first sediment separator 201 and a second annular groove on the second sediment separator 202, the captured sediment can be temporarily stored without significantly increasing the water flow resistance, preventing the separated sediment from being flushed up again by the subsequent water flow, thus ensuring the continuous stability of the separation efficiency.

[0028] In summary, this utility model overcomes the various shortcomings of the prior art.

[0029] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model.
