Description

Technical Field

[0001] This utility model relates to the field of sediment sampling technology, and in particular to a water and soil conservation runoff sediment sampling device. Background Technology

[0002] Runoff refers to the process by which rainfall, snowmelt, or other water sources flow across the surface or underground, eventually forming rivers, lakes, or entering groundwater systems. It is a crucial link in the water cycle. In the natural environment, runoff can carry sediment, nutrients, and pollutants, impacting soil, vegetation, and water quality. Runoff is divided into surface runoff and groundwater runoff. The former refers to water flowing at the earth's surface, while the latter refers to water that has infiltrated into the soil layer and continues to flow. The formation and magnitude of runoff are influenced by various factors, including rainfall intensity, soil permeability, topography, and vegetation cover. Effective management of runoff is of great significance for soil and water conservation, flood prevention, and water resource protection.

[0003] In managing runoff, regular sampling of runoff sediment is necessary, requiring specialized sediment sampling equipment. Currently, existing sediment sampling equipment lacks effective filtration structures, making it difficult to adequately filter out impurities such as gravel and aquatic plants from the runoff sediment. Furthermore, existing equipment does not completely separate water from the runoff sediment during processing, which may impose limitations in practical operation.

[0004] Based on this, we propose a soil and water conservation runoff sediment sampling device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a water and soil conservation runoff sediment sampling device that can solve the problem that existing sediment sampling devices are difficult to effectively filter impurities such as gravel and aquatic plants in runoff sediment and separate a small amount of water during sampling.

[0007] To solve the above technical problems, this utility model provides a water and soil conservation runoff sediment sampling device, which adopts the following technical solution: it includes a mobile chassis, a first sampling component is installed on the top of the mobile chassis, a second sampling component is connected to the top of the first sampling component, the second sampling component includes a guide bucket, a bucket cover is provided on the top of the guide bucket, and an impurity filter screen is provided in the middle of the bucket cover;

[0008] The first sampling component includes a filter box, a liquid storage drawer is slidably connected to one side of the filter box, and a separation drawer is slidably connected to the top of the side of the filter box near the liquid storage drawer.

[0009] Optionally, the top of the filter box has a through-hole, and the bottom two sides of the filter box are respectively connected to fixing plates.

[0010] Optionally, the bottom of the guide bucket is connected to a discharge pipe, which is matched with the discharge inlet structure. The discharge pipe and the discharge inlet are connected by a plug-in fit. The four corners of the bottom of the guide bucket are also connected with positioning pins.

[0011] Optionally, the bucket cover includes a metal cover that matches the structure of the guide bucket. The metal cover and the guide bucket are connected by a sleeve. The top two sides of the metal cover are also connected to handles.

[0012] Optionally, support rods are connected to the top four corners of the mobile chassis, and positioning holes are opened on the top of the four sets of support rods. A movable push handle is also connected between the outer sides of two sets of support rods.

[0013] Optionally, the positioning hole and the positioning pin are matched in structure, and the positioning hole and the positioning pin are in a snap-fit ​​engagement.

[0014] In summary, this utility model has at least one of the following beneficial effects:

[0015] 1. This solution uses a lid on top of the guide hopper. Because the lid's structure matches the guide hopper, it can be securely installed on top of the guide hopper. When runoff sediment samples are poured into the guide hopper, the impurity filter screen installed in the middle of the lid can effectively screen out impurities such as gravel and aquatic plants from the runoff sediment samples. By using positioning pins installed at the four corners of the bottom of the guide hopper, which correspond to the positioning holes opened at the top of the support rod, the guide hopper with the lid can be securely fixed to the top of the mobile chassis through a snap-fit ​​connection. With the discharge inlet at the top of the filter box and the discharge pipe connected to the bottom of the guide hopper, a channel can be formed between the guide hopper and the filter box through a plug-in connection. When runoff sediment samples are poured into the guide hopper, not only can impurities such as gravel and aquatic plants in the runoff sediment samples be filtered out, but the filtered runoff sediment samples can also be discharged into the interior of the filter box through the discharge pipe.

[0016] 2. This solution uses a liquid storage drawer and a separation drawer that are slidably connected on one side of the filter box. When the runoff sediment sample enters the filter box, it falls into the interior of the separation drawer. The separation drawer, through a fine mesh filter installed at its bottom, can filter out the small amount of water contained in the runoff sediment sample, thus separating the sediment from the water. The separated water flows into the interior of the liquid storage drawer through the fine mesh filter, so that the treated runoff sediment sample is retained in the separation drawer for subsequent testing by the staff.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Refer to Figures 1 to 6 According to one embodiment of the present invention, a water and soil conservation runoff sediment sampling device includes a mobile chassis 1, a first sampling component 2 is installed on the top of the mobile chassis 1, and a second sampling component 3 is connected to the top of the first sampling component 2. The second sampling component 3 includes a guide bucket 4, a bucket cover 5 is provided on the top of the guide bucket 4, and an impurity filter screen 6 is provided in the middle of the bucket cover 5.

[0027] The first sampling component 2 includes a filter box 7. A liquid storage drawer 8 is slidably connected to one side of the filter box 7. A separation drawer 9 is also slidably connected to the top of the filter box 7 near the liquid storage drawer 8. The first sampling component 2 and the second sampling component 3 constitute the core mechanism for sampling and processing. The guide bucket 4 is used to receive and guide the runoff sediment sample. The bucket cover 5 and the impurity filter screen 6 in the middle are responsible for the preliminary filtration of impurities such as gravel and aquatic plants in the runoff sediment sample to ensure the cleanliness of the runoff sediment sample. The liquid storage drawer 8 and the separation drawer 9 slidably connected to one side of the filter box 7 can effectively separate the liquid and sediment in the runoff sediment sample. The top of the filter box 7 has a through-hole opening 10. The bottom two sides of the filter box 7 are respectively connected to the fixing plates 11. Through the through-hole opening 10 at the top of the filter box 7, the guide bucket 4 can discharge the filtered runoff sediment sample into the interior of the filter box 7.

[0028] The bottom of the guide bucket 4 is connected to a discharge pipe 12, which is structurally matched with the discharge inlet 10. The discharge pipe 12 and the discharge inlet 10 are connected by a plug-in fit. The four corners of the bottom of the guide bucket 4 are also connected to positioning pins 13. Through the structural design of the plug-in fit between the discharge pipe 12 and the discharge inlet 10, the guide bucket 4 mounted on the top of the mobile chassis 1 can be connected to the top of the filter box 7. The bucket cover 5 includes a metal cover 14, which is structurally matched with the guide bucket 4. The metal cover 14 and the guide bucket 4 are connected by a sleeve fit. The top two sides of the metal cover 14 are also connected to handles 15. Through the structural design of the metal cover 14 and the guide bucket 4, and the sleeve fit between the metal cover 14 and the guide bucket 4, the bucket cover 5 with the impurity filter screen 6 installed in the middle can be fitted onto the top of the guide bucket 4.

[0029] Support rods 16 are connected to the four corners of the top of the mobile chassis 1. Positioning holes 17 are opened on the top of the four sets of support rods 16 respectively. A movable push handle 18 is also connected between the outer sides of two sets of support rods 16. By adding support rods 16 to the four corners of the top of the mobile chassis 1, the four corners of the guide bucket 4 installed on the top of the filter box 7 can be supported upward. The positioning holes 17 and positioning pins 13 are structurally matched and are engaged. Through the engagement structure between the positioning holes 17 and positioning pins 13, the guide bucket 4 with the bucket cover 5 on the top can be mounted on the top of the mobile chassis 1, which can effectively improve the stability of the connection between the mobile chassis 1, the first sampling component 2, and the second sampling component 3.

[0030] Working Principle: This solution uses a lid 5 installed on top of the guide bucket 4. Because the lid 5 matches the structure of the guide bucket 4, it can be fitted onto the top of the guide bucket 4. When the collected runoff sediment sample is poured into the guide bucket 4, the impurity filter 6 installed in the middle of the lid 5 can filter out impurities such as gravel and aquatic plants. Positioning pins 13 are installed at the four corners of the bottom of the guide bucket 4, and positioning holes 17 are opened at the top of the support rod 16. Because the positioning holes 17 and positioning pins 13 are interlocked, the lid 5 can be fitted onto the top of the guide bucket 4. The guide bucket 4 of the cover 5 is mounted on the top of the mobile chassis 1, and is connected to the discharge inlet 10 that is opened through the top of the filter box 7, and the discharge pipe 12 connected to the bottom of the guide bucket 4. The discharge pipe 12 and the discharge inlet 10 are plugged in. The guide bucket 4 mounted on the top of the mobile chassis 1 can also be connected through to the top of the filter box 7. When the runoff sediment sample is poured into the interior of the guide bucket 4, the guide bucket 4 can filter out the impurities such as gravel and aquatic plants contained in the runoff sediment sample, and can also discharge the filtered runoff sediment sample into the interior of the filter box 7.

[0031] This solution uses a liquid storage drawer 8 and a separation drawer 9 that are slidably connected on one side of the filter housing 7. When the filtered runoff sediment sample is discharged from the guide bucket 4 into the interior of the filter housing 7, the runoff sediment sample discharged into the filter housing 7 will fall into the separation drawer 9. The bottom of the separation drawer 9 is equipped with a fine mesh filter for river water seepage, which can separate the river water contained in the runoff sediment sample. The separated river water can fall into the liquid storage drawer 8 through the fine mesh filter, so that the runoff sediment to be tested can be completely retained inside the separation drawer 9 for use by staff in subsequent testing.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
