Abstract
Description
Technical Field
[0001] This utility model belongs to the field of river sediment sampling technology, and in particular relates to a river sediment sampling device. Background Technology
[0002] Therefore, to address river pollution, it is necessary to sample rivers, including water samples and samples of sediment deposited at the riverbed. Specifically, large amounts of pollutants settle at the riverbed, forming highly polluted silt. Therefore, by sampling sediments, the extent of river pollution can be accurately determined, leading to more effective river management solutions.
[0003] During sampling, current methods involve inserting a probe of a certain length into the riverbed, allowing silt to enter the probe's cavity. However, in actual sampling and testing, there are certain requirements for the sample volume; the amount of sediment sampled needs to meet a certain weight requirement to facilitate subsequent testing. Traditional sampling probes, however, yield very small samples. This is because the silt sample is heavy, and during the process of lifting the probe up from the river (after sampling, lifting the probe facilitates the removal of the silt sample), a large amount of the silt sediment inside the probe easily slips out, resulting in an insufficient sample volume.
[0004] However, the depth to which the probe can be embedded in the silt layer at the bottom of the river is limited. Therefore, in order to obtain a sufficient amount of silt sample, current technology can only require frequent sampling. At the same time, because the probe sampling method is relatively blind, it is impossible to observe the condition of the river bottom during the sampling process. As a result, once the probe is inserted into a gap such as between rocks, it becomes difficult to pull it out. Utility Model Content
[0005] Based on the above background, the purpose of this utility model is to provide a river sediment sampling device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A river sediment sampling device includes a sampling rod, an end of which is fixedly connected to a mounting base, and a sampling scoop mechanism is mounted on the mounting base; the sampling scoop mechanism includes a lower sampling scoop body and an upper cover scoop body that cooperates with the lower sampling scoop body.
[0008] The sampling scoop includes a scoop section for accommodating the collected sample. Both ends of the scoop section are integrally formed with shovels. During use, the shovels work together to scoop the sample into the scoop section.
[0009] The sampling ladle mechanism also includes a push rod structure that pushes the upper ladle cover onto the lower sampling ladle body, and a flip rod structure that drives the lower sampling ladle body to flip and sample.
[0010] Preferably, the sampling ladle body and the upper cover ladle are arranged symmetrically vertically.
[0011] Both the sampling gourd body and the top cover gourd have hemispherical groove structures.
[0012] Preferably, the sampling rod includes a rod body, and a handle is fixedly connected to the front end of the rod body;
[0013] The mounting base is fixedly connected to the rear end of the rod body.
[0014] Preferably, the push rod structure includes a push rod fixedly connected to the front side wall of the upper cover, and a short push handle is fixedly connected to the front end of the push rod;
[0015] The push rod is slidably connected to the mounting base;
[0016] A fixed seat that slides on the push rod is fixedly connected to the rod body.
[0017] Preferably, the flipping rod structure includes a flipping rod fixedly connected to the front side wall of the sampling scoop body, and the flipping rod is rotatably connected to the mounting base.
[0018] Preferably, a handle base is fixedly connected to the front end of the flipping rod.
[0019] Preferably, the river sediment sampling device further includes a monitoring structure;
[0020] The monitoring structure includes a camera bracket fixedly connected to the top of the mounting base, and a monitoring camera is fixedly mounted on the camera bracket;
[0021] A display screen mounting base is fixedly connected to the front side of the pole body, and a display screen that works with a surveillance camera is mounted on the top of the display screen mounting base.
[0022] Preferably, both the push rod and the flip rod pass through the display screen mounting base;
[0023] The push rod is slidably connected to the display screen mounting base, and the flip rod is rotatably connected to the display screen mounting base.
[0024] Preferably, a probe cone is fixedly connected to the rear side wall of the sampling gourd body.
[0025] This utility model has the following beneficial effects:
[0026] 1. During operation, when the sampling scoop mechanism extends to the bottom of the river, the lower sampling scoop body is offset from the upper cover scoop, exposing the lower sampling scoop body. The operator then uses the sampling rod to fill the lower sampling scoop body with sample from the river bottom. Subsequently, to prevent sample loss due to water flow during the process of lifting the sample to the surface, the upper cover scoop is closed onto the top of the lower sampling scoop body, forming a spherical, relatively sealed structure. This method increases the sample volume while preventing sample loss after sampling and also prevents suspended or floating debris such as aquatic plants from entering the sample.
[0027] 2. The push rod structure enables the upper cover to be pushed apart from the lower sampling ladle during the sampling process, and the upper cover to be closed after sampling, making it easy to operate the upper cover.
[0028] 3. The flip-rod structure facilitates the flipping of the sampling ladle during sampling, enabling it to scoop up large amounts of sediment sample. During the flipping process, the upper ladle and the sampling ladle are misaligned, allowing the sampling ladle to rotate freely.
[0029] 4. The monitoring structure facilitates observation of the sampling location at the bottom of the river during the sampling process, helps avoid obstacles such as rocks, and allows for precise sampling of the sample volume from the sampling gourd, while also facilitating manual operation.
[0030] 5. By using a probing cone, the sampler continuously probes the silt layer before sampling to check for hard obstacles, thus avoiding contact with hard obstacles such as rocks during the sampling process. Attached Figure Description

[0040] Example 1
[0041] like Figure 1-4 As shown, a river sediment sampling device includes a sampling rod 1. The sampling rod 1 has the following structure: a rod body 12 is included, and a handle 11 is fixedly connected to the front end of the rod body 12 (for convenient hand operation during sampling). A mounting base 3 (columnar structure) is fixedly connected to the rear end of the rod body 12, and a sampling scoop mechanism 4 is mounted on the mounting base 3. The sampling scoop mechanism 4 increases the amount of sediment (silt) collected from the bottom of the river during sampling, meeting the needs of subsequent testing.
[0042] Specifically, the sampling scoop mechanism 4 includes a sampling scoop body 41 and an upper cover scoop 42 that cooperates with the sampling scoop body 41. Specifically, the sampling scoop body 41 includes a scoop section (hemispherical in shape) for accommodating the collected sample, with buckets 411 integrally formed at both ends of the scoop section (the buckets 411 have guide grooves). Similarly, the upper cover scoop 42 is identical in size and structure to the sampling scoop body 41, and the two are arranged symmetrically.
[0043] Specifically, both the lower sampling gourd body 41 and the upper cover gourd 42 have hemispherical groove structures (the groove structure is located on the gourd body and is hemispherical in shape).
[0044] During operation, when the sampling ladle mechanism 4 extends to the bottom of the river, the lower sampling ladle body 41 is offset from the upper cover ladle 42, exposing the lower sampling ladle body 41. The operator then uses the sampling rod 1 to scoop up the sample from the bottom of the river using the lower sampling ladle body 41. Subsequently, to prevent sample loss due to water flow during the process of lifting the sample out of the water, the upper cover ladle 42 is placed on top of the lower sampling ladle body 41 to form a spherical, relatively sealed structure. This method can increase the sampling volume, prevent sample loss after sampling, and also prevent suspended or floating debris such as aquatic plants from entering the sample.
[0045] During the sampling process, the shovel 411 facilitates sampling. Specifically, during the scooping process, the shovel head is used to loosen the sediment being sampled, making it easier to scoop into the sampling ladle 41.
[0046] Example 2
[0047] like Figure 1-4 As shown, based on the structure of Embodiment 1, in order to facilitate sampling after the upper cover 42 and the lower sampling ladle 41 are offset during the sampling process, and to close the ladle after sampling, the sampling ladle mechanism 4 also includes a push rod structure that pushes the upper cover 42 to close onto the lower sampling ladle 41.
[0048] Specifically, the push rod structure includes a push rod 421 fixedly connected to the front side wall of the upper cover 42, and a short push handle 1211 fixedly connected to the front end of the push rod 421; the push rod 421 is slidably connected to the mounting base 3.
[0049] Meanwhile, in order to increase the stability of pushing, pulling and sliding, a fixed seat 121 that is slidably connected to the push rod 421 is fixedly connected to the front side of the aforementioned rod body 12.
[0050] During operation, because the short push handle 1211 is close to the operator's hand, the operator can push the operating push rod 421 through the short push handle 1211 to achieve convenient operation.
[0051] Example 3
[0052] like Figure 1-4 As shown, based on the structure of Embodiment 2, in order to further facilitate the operation of the sampling ladle 41 and make it easier for the sampling ladle 41 to scoop up the sample during the sampling process, the sampling ladle mechanism 4 also includes a flip bar structure that drives the sampling ladle 41 to flip and sample.
[0053] Specifically, the flip-rod structure includes a flip-rod 441 fixedly connected to the front side wall of the sampling scoop body 41, and the flip-rod 441 is rotatably connected to the mounting base 3. A handle seat 4411 is fixedly connected to the front end of the flip-rod 441.
[0054] During operation, the operator uses the handle 4411 to rotate the sampling ladle 41, which in turn drives the ladle body 41 to flip. During this flipping motion, the sampling ladle body 41 scoops up a large amount of sediment sample, facilitating the scooping of this sample into the ladle body. Because the upper cover ladle 42 is offset from the sampling ladle body 41, the ladle body 41 can flip freely during the flipping process.
[0055] Example 4
[0056] like Figure 1-4 As shown, based on the structure of Example 3, this embodiment includes a monitoring structure 2 in order to observe the sampling location at the bottom of the river, avoid obstacles such as rocks during the sampling process, and facilitate the sampling process by reducing the sample volume of the sampling gourd 41 and the corresponding hand operation.
[0057] Specifically, the monitoring structure 2 includes a camera bracket 21 fixedly connected to the top of the mounting base 3, on which a monitoring camera 24 is fixedly mounted. Similar to existing technologies, the monitoring camera 24 is a small camera with high waterproof performance (i.e., the monitoring camera 24 is a conventionally used submersible underwater camera disclosed in the prior art). The data cable for the camera is laid along the length of the pole body 12.
[0058] Similar to existing technology, a display screen mounting base 3 is fixedly connected to the front side of the pole body 12, and a display screen 22 that cooperates with the surveillance camera 24 is mounted on the top of the display screen mounting base 3. The display screen 22 is a conventional display screen 22 disclosed in the prior art that works in conjunction with a camera, capable of displaying the images monitored by the camera. That is, the surveillance camera 24 is played back through the display screen 22.
[0059] Both the push rod 421 and the flip rod 441 pass through the display screen mounting base 23. Simultaneously, the push rod 421 is slidably connected to the display screen mounting base 23, and the flip rod 441 is rotatably connected to the display screen mounting base 23.
[0060] Example 5
[0061] like Figure 1-4 As shown, this embodiment, based on the structure of embodiment 4, uses a monitoring camera 24 to observe the sampling location during sampling, thus avoiding obstacles such as stones. However, in actual operation, it was found that stones were easily buried in the silt at the sampling location, making them invisible to the camera. Therefore, to further probe the condition of the lower layer of silt at the sampling location before scooping the sample, a probing cone 43 is fixedly connected to the rear side wall of the aforementioned sampling scoop 41. Before sampling, the probing cone 43 is continuously inserted into the silt layer to check for hard obstacles, thus avoiding contact with hard obstacles such as stones during sampling.
[0062] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
