Abstract
Description
Technical Field
[0001] This utility model relates to the field of silt sampling technology, and in particular to a river silt sampling device. Background Technology
[0002] Stream sediments (bottom sediments) are mixtures of clay, silt, organic matter, and various minerals formed at the bottom of water bodies through long-term physical, chemical, and biological processes and water transport. Heavy metal pollutants are ubiquitous in the environment, characterized by their difficulty in degradation and their ability to accumulate. Heavy metal pollutants enter water bodies through precipitation runoff, industrial wastewater, and domestic sewage discharge. Therefore, monitoring and evaluating heavy metal pollution in the bottom sediments of rivers, waterways, and lakes is of great significance.
[0003] In related technologies, samplers are usually used vertically downwards, but sometimes they are inconvenient to operate and sometimes cannot be sampled, especially in waterways without boats. Utility Model Content
[0004] The main purpose of this utility model is to propose a river silt sampling device, which aims to at least solve the technical problem that in related technologies, samplers are usually used vertically downwards, but sometimes they are inconvenient to operate and sometimes cannot be sampled, especially in rivers without boats.
[0005] To achieve the above objectives, this utility model proposes a river silt sampling device, comprising:
[0006] Base plate;
[0007] Two grabs are arranged opposite each other, and the upper ends of the two grabs are rotatably connected to the base plate so as to have a grab position with the lower ends closed and a release position with the lower ends open.
[0008] An extension rod is disposed on the upper side of the base plate and is inclined relative to the base plate; and,
[0009] A drive unit is connected to the two grab buckets to drive the two grab buckets to rotate.
[0010] In one embodiment, the drive element includes a rope connected to the two grab buckets.
[0011] In one embodiment, the rope comprises two rope segments, one end of which is connected to each other, and the other end of which is fixedly connected to the two grabs respectively.
[0012] In one embodiment, a first handle is fixedly provided at the end of the extension rod away from the base plate;
[0013] The river silt sampling device also includes a second handle that is rotatably mounted on the extension rod. The second handle is positioned opposite to the first handle and is located below the first handle.
[0014] The joint between the two rope segments is fixedly connected to the second grip.
[0015] In one embodiment, the extension rod has an inlet end, an outlet end, and a connecting channel connecting the inlet end and the outlet end;
[0016] The outlet end is located below the rotatable connection between the second grip and the extension rod;
[0017] The connection point of the two rope segments passes through the connecting channel from the inlet end to the outlet end.
[0018] In one embodiment, the junction of the two rope segments is fixedly connected to the side of the second grip facing the first grip.
[0019] In one embodiment, a reset member is further provided between the base plate and the grab bucket, the reset member being used to reset the grab bucket to the release position.
[0020] In one embodiment, the grab bucket is provided with filter holes that connect its interior to the outside.
[0021] In one embodiment, the river silt sampling device further includes an adjustment structure disposed between the base plate and the extension rod, the adjustment structure being used to adjust the angle between the extension rod and the base plate.
[0022] In one embodiment, the adjustment structure includes:
[0023] Two clamping plates are fixedly installed on the upper side of the base plate and are arranged opposite to each other;
[0024] Screws are inserted through the two clamps in a horizontal direction;
[0025] A nut, threadedly connected to the screw, and abutting against the outer side of one of the clamps;
[0026] The extension rod is rotatably mounted on the screw and clamped between the two clamping plates.
[0027] In the technical solution of this utility model, the river silt sampling device includes a base plate, two grab buckets, an extension rod, and a driving component. The two grab buckets are arranged opposite to each other, and the upper ends of the two grab buckets are rotatably connected to the base plate. The extension rod is arranged on the upper side of the base plate and is inclined relative to the base plate. The driving component is drivenly connected to the two grab buckets. Thus, when sampling river silt, the two grab buckets are extended into the riverbed through the extension rod, and then the two grab buckets are driven to rotate through the driving component, so that the lower ends of the two grab buckets close together, thereby grabbing the silt. Since the extension rod is inclined relative to the base plate, sampling can be carried out smoothly on the bank even in rivers without boats. Attached Figure Description

[0038] Aquatic sediments (bottom sediments) are mixtures of clay, silt, organic matter, and various minerals formed at the bottom of water bodies through long-term physical, chemical, and biological processes and water transport. Heavy metal pollutants are ubiquitous in the environment, characterized by their difficulty in degradation and their ability to accumulate. Heavy metal pollutants enter water bodies through precipitation runoff, industrial wastewater, and domestic sewage discharge. Therefore, monitoring and evaluating heavy metal pollution in the bottom sediments of rivers, waterways, and lakes is of great significance. In related technologies, samplers are usually used vertically downwards, but this can sometimes be inconvenient to operate and may result in failure to collect samples, especially in waterways without boats.
[0039] The main purpose of this utility model is to propose a river silt sampling device, which aims to at least solve the technical problem that in related technologies, samplers are usually used vertically downwards, but sometimes they are inconvenient to operate and sometimes cannot be sampled, especially in rivers without boats.
[0040] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the river silt sampling device 100 includes a base plate 1, two grab buckets 2, an extension rod 3, and a driving component 4. The two grab buckets 2 are arranged opposite to each other, and the upper ends of the two grab buckets 2 are rotatably connected to the base plate 1 to have a grab position with the lower ends closed and a release position with the lower ends open. The extension rod 3 is arranged on the upper side of the base plate 1 and is inclined relative to the base plate 1. The driving component 4 is drivenly connected to the two grab buckets 2 to drive the two grab buckets 2 to rotate.
[0041] In the technical solution of this utility model, the river silt sampling device 100 includes a base plate 1, two grab buckets 2, an extension rod 3, and a driving component 4. The two grab buckets 2 are arranged opposite to each other, and the upper ends of the two grab buckets 2 are rotatably connected to the base plate 1. The extension rod 3 is arranged on the upper side of the base plate 1 and is inclined relative to the base plate 1. The driving component 4 is drivenly connected to the two grab buckets 2. Thus, when sampling river silt, the two grab buckets 2 are extended into the riverbed by the extension rod 3, and then the two grab buckets 2 are driven to rotate by the driving component 4, so that the lower ends of the two grab buckets 2 are closed, thereby grabbing the silt. Since the extension rod 3 is inclined relative to the base plate 1, sampling can be carried out smoothly on the bank even in rivers without boats.
[0042] In order to drive the two grabs 2 to rotate, the drive unit 4 can be driven manually or automatically. In the embodiments of this utility model, please refer to... Figure 1 and Figure 2 The driving component 4 includes a rope 41, which is drivenly connected to the two grab buckets 2. Thus, driving the two grab buckets 2 to rotate via the rope 41 is obviously less costly than an electric method, such as using a motor to drive the grab buckets 2, and the overall weight of the river silt sampling device 100 is also lower.
[0043] There are several ways to drive the two grab buckets 2 using the rope 41. In some embodiments, the middle part of the rope 41 can be slidably connected to the two grab buckets 2 respectively. In this case, pulling both ends of the rope 41 simultaneously will cause the lower ends of the two grab buckets 2 to close, thereby moving them to the grabbing position to grab the silt in the river channel. In some embodiments, the rope 41 includes two rope segments, one end of which is connected to each other, and the other end is fixedly connected to the two grab buckets 2 respectively. With this configuration, when driving the two grab buckets 2 to close using the rope 41, only the connection point of the two rope ends needs to be pulled, which is equivalent to pulling the middle part of the rope 41.
[0044] It is understandable that when the two grab buckets 2 are driven by the rope 41, it is easier for the two grab buckets 2 to close. However, the opening of the two grab buckets 2 usually requires their own gravity or manual prying. This is inconvenient whether opening before sampling or releasing after sampling. Moreover, when the two grab buckets 2 are inserted into the water, they may automatically close under the influence of water pressure. To facilitate the operation of the overall river silt sampling device 100, in this embodiment of the invention, a reset member 7 is provided between the base plate 1 and the grab bucket 2. The reset member 7 is used to reset the grab bucket 2 to the release position. Thus, by providing the reset member 7 between the base plate 1 and the grab bucket 2, the two grab buckets 2 can be kept in the release position so that they can normally grab river silt. When the two grab buckets 2 need to be closed, the force exerted on the grab buckets 2 by the reset member 7 can be overcome by the rope 41. After the grab is completed, the force exerted on the rope 41 is released, and the two grab buckets 2 will automatically open under the action of the reset member 7, thereby releasing the grabbed silt.
[0045] The reset element 7 can take many forms. In some embodiments, a tension spring can be provided between the grab bucket 2 and the base plate 1. In some embodiments, the reset element 7 includes a torsion spring provided at the rotational connection between the base plate 1 and the grab bucket 2. Compared with the tension spring, the torsion spring has a smaller overall structure space and can reduce the possibility of being stuck by impurities.
[0046] For further information, please refer to [link / reference]. Figure 1 In this embodiment of the invention, a first handle 5 is fixedly provided at the end of the extension rod 3 away from the base plate 1; the river silt sampling device 100 also includes a second handle 6 rotatably disposed on the extension rod 3, the second handle 6 being opposite to the first handle 5 and located below the first handle 5; the connection point of the two rope segments is fixedly connected to the second handle 6. Thus, in use, the first handle 5 supports the entire river silt sampling device 100. After the two grab buckets 2 extend to the river bottom, pressing the second handle 6 causes it to rotate, which pulls the two rope segments, causing the lower ends of the two grab buckets 2 to close, thereby grabbing the river silt. When release is needed, the second handle 6 is released.
[0047] It is understandable that if the rope 41 is exposed to the outside environment, there is a risk of interference from other debris during practical use, which may affect the normal operation of the entire river silt sampling device 100. For details, please refer to the embodiments of this utility model. Figure 1 and Figure 2The extension rod 3 has an inlet end 31, an outlet end 32, and a connecting channel 33 connecting the inlet end 31 and the outlet end 32. The outlet end 32 is located below the rotatable connection between the second grip 6 and the extension rod 3. The connection point of the two rope segments passes through the connecting channel 33 from the inlet end 31 to the outlet end 32. This arrangement effectively hides most of the rope 41 within the connecting channel 33 of the extension rod 3, protecting the rope 41 so that only a small portion of the rope 41 is exposed to the outside. This guides the rope 41 while reducing interference from external debris.
[0048] The connecting channel 33 can be an additional opening or it can be a channel that is already present in the extension rod 3, such as a steel pipe.
[0049] In order to reduce the interference of the rope 41 on the user pressing the second grip 6, in an embodiment of the present invention, the connection point of the two rope segments is fixedly connected to the side of the second grip 6 facing the first grip 5.
[0050] It is understandable that when the angle between the extension rod 3 and the base plate 1 is fixed, the depth of the river silt sampling device 100 that can be sampled is limited, unless the extension rod 3 is designed to be very long. However, this would result in a heavier overall weight and make it inconvenient to carry. Therefore, in this embodiment of the present invention, the river silt sampling device 100 further includes an adjustment structure 8 disposed between the base plate 1 and the extension rod 3. The adjustment structure 8 is used to adjust the angle between the extension rod 3 and the base plate 1. With this configuration, the sampling depth of the grab bucket 2 can be adjusted by adjusting the angle between the extension rod 3 and the base plate 1. At the same time, when sampling in rivers with boats, the extension rod 3 and the base plate 1 can be adjusted to a vertical state, which allows for better sampling and a wider range of applicability of the overall structure.
[0051] The adjustment structure 8 has various forms. Please refer to the embodiments of this utility model. Figure 2The adjustment structure 8 includes two clamping plates 81, a screw 82, and a nut 83. The two clamping plates 81 are fixedly disposed on the upper side of the base plate 1 and are arranged opposite each other. The screw 82 passes through the two clamping plates 81 in a horizontal direction. The nut 83 is threadedly connected to the screw 82 and abuts against the outer side of one of the clamping plates 81. The extension rod 3 is rotatably disposed on the screw 82 and clamped between the two clamping plates 81. Thus, when it is necessary to adjust the angle of the extension rod 3, the nut 83 is rotated to loosen the two clamping plates 81, allowing the extension rod 3 to rotate on the screw 82 to adjust the angle. After adjustment, the nut 83 is tightened, causing the nut 83 to press against one of the clamping plates 81, thereby deforming the clamping plate 81 to clamp the extension rod 3, thus keeping the extension rod 3 fixed.
[0052] Immediately, when the grab bucket 2 grabs silt, it will bring up water from the river channel, making the entire river silt sampling device 100 very heavy. In order to reduce the weight, in some embodiments, please refer to... Figure 3 The grab bucket 2 is provided with a filter hole 21 that connects its interior and the outside. In this way, water can be discharged from the grab bucket 2 through the filter hole 21, making the overall weight lighter and making it easier to lift the river silt sampling device 100 onto the shore. At the same time, after the silt is extracted and put into the container, water can also be discharged through the filter hole 21 before it is put into the container, so that the container can hold more silt samples while also being lighter.
[0053] Of course, to further improve the sampling range, in some embodiments, the extension rod 3 can be configured as a telescopic rod. The above descriptions are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of this utility model's specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
