Description

Technical Field

[0001] This utility model relates to the field of sediment collection technology, specifically a hydrological sediment collection device. Background Technology

[0002] Hydrological sediment sampling devices are used in water conservancy projects, hydrological monitoring, environmental assessment and other fields. Sediment samples can be collected at fixed points or dynamically to collect sediment samples and supporting hydrological parameters (such as flow velocity, water level and sediment content) in water bodies. Its core value lies in providing scientific basis for watershed management, reservoir scheduling, waterway maintenance and ecological protection by accurately acquiring sediment data. Hydrological sediment sampling devices are key tools for understanding the laws of sediment movement in water bodies and assessing the degree of soil erosion or sediment deposition.

[0003] Existing hydrological sediment sampling devices include those that directly insert sampling tubes into the sediment and close the upper outlet valve during the upward movement after sampling to allow the sampled sediment to be carried out of the water. However, in this method, sediment can easily fall off from the bottom of the sampling tube, affecting the sampling results. Other devices use a method of merging the left and right buckets towards the middle for sampling. This structure can only collect sediment located near the top of the water body and cannot sample deep into the sediment. Furthermore, the process of the left and right buckets probing into the sediment and then merging causes significant disturbance to the sediment, which also affects the accuracy of the sampled sediment data. Utility Model Content

[0004] The purpose of this invention is to provide a hydrological sediment sampling device to address the problems mentioned in the background section regarding existing hydrological sediment sampling devices. Some devices directly insert the sampling tube into the sediment, and close the upper outlet valve during the upward movement after sampling to allow the sampled sediment to be carried out of the water. However, in this method, the sediment can easily fall off from the bottom of the sampling tube, affecting the sampling results. Other devices use a method of merging the left and right buckets towards the middle for sampling. This structure can only collect sediment located near the top of the water body and cannot sample deep into the sediment. Furthermore, the process of the left and right buckets probing into the sediment and then merging causes significant disturbance to the sediment, which also affects the accuracy of the sampled sediment data.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A hydrological sediment collection device includes a frame, a drive assembly, and a collection mechanism. The drive assembly is connected to the lower part of the frame, and the collection mechanism is connected to the lower part of the drive assembly. The drive assembly includes a first linear actuator, and the collection mechanism is vertically slidably connected to the frame via the first linear actuator. The collection mechanism includes a positioning seat, a connecting frame, a first side plate, and a second side plate. The positioning seat is connected to the output end of the first linear actuator, and the lower part of the positioning seat is fixedly connected to the connecting frame. Two first side plates are fixedly fixed parallel to each other below the connecting frame. Positioning elements are provided on opposite sides of the two first side plates, and U-shaped grooves are provided on the positioning elements. The second side plate is slidably connected between the two first side plates, and the edge of the second side plate is inserted into the U-shaped groove. The second side plate is made of a flexible and bendable material.

[0006] Preferably, two second side plates are provided, symmetrically distributed at both ends of the U-shaped groove. The two second side plates slide up and down in the U-shaped groove through a second linear actuator. The body of the second linear actuator is fixed below the connecting frame. The output end of the second linear actuator is fixedly connected to the fixed connector. The upper ends of the two second side plates are fixedly connected to the fixed connector.

[0007] Preferably, each of the two second side plates has a third inclined surface at one end of its closest point in the U-shaped groove, and the third inclined surfaces of the two second side plates are joined together when the two second side plates are in the U-shaped groove.

[0008] Preferably, the lower end of the positioning member is provided with a second inclined surface, and the lower end of the first side plate is provided with a first inclined surface that extends from the second inclined surface of the positioning member.

[0009] Preferably, the drive assembly further includes a motor. The first linear driver is connected to the frame via the motor rotation. A connecting seat is provided at the output end of the first linear driver. The connecting seat is connected to the positioning seat. An external protrusion is provided on the periphery of the connecting seat. A slot is opened on the upper part of the positioning seat. An internal protrusion is provided near the upper edge of the slot. The slot matches the connecting seat. When the external protrusion of the connecting seat rotates to a position below the non-internal protrusion of the slot, the connecting seat can be separated from the positioning seat. When the external protrusion of the connecting seat rotates to a position below the internal protrusion of the slot, the connecting seat and the positioning seat are connected together.

[0010] Preferably, a sediment collection and movement assembly is provided on the side of the frame. The sediment collection and movement assembly includes a support rod, a sliding member, and a support plug. The support rod is fixedly connected to the frame, the sliding member is slidably connected below the support rod, and the support plug is located on the side of the sliding member facing the first linear actuator. The support plug is inserted into a positioning seat, and the side of the positioning seat connected to the support plug has a cut-out snap-fit ​​surface. An outward protrusion is provided above the snap-fit ​​surface of the positioning seat.

[0011] Preferably, a slide rail is provided below the support rod, and a slider is provided above the slider. The slider is laterally slidably connected to the slide rail. The sediment collection and movement assembly also includes a third linear actuator. The body of the third linear actuator is fixedly connected to the frame, and the output end of the third linear actuator is connected to the slider.

[0012] Preferably, a connecting bracket is provided on the side of the support rod near the first linear actuator, and the connecting bracket is connected to the periphery of the first linear actuator body via a bearing.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. With the setting of the first side plate and the second side plate, the second side plate is also inserted vertically into the mud and sand. When the sampling mechanism stops at the height position to be sampled in the mud and sand, the second side plate slides to wrap the mud and sand in the bottom area of ​​the U-shaped groove between the first side plate. When the second side plate slides to the bottom position of the U-shaped groove, the second side plate bends with the shape of the U-shaped groove.

[0014] 2. This utility model utilizes two second side plates. A second linear actuator drives a fixed connector to simultaneously slide the two second side plates downwards in a U-shaped groove. As they move to the arc-shaped portion of the U-shaped groove, the two second side plates bend and merge together, encasing the sediment to be sampled in the upper area containing the first side plate. Initially, the second side plates are vertically oriented. This, together with the vertical structure of the first side plate, makes the entire sampling mechanism smoother when inserted into the sediment, reducing disturbance to the sediment and improving the accuracy of the sampled sediment data. When the two second side plates slide and deform before merging together, they effectively physically isolate the bottom of the sampled sediment, preventing it from falling off during lifting in the water. This protects the sediment at the bottom of the sampled sediment, potentially preserving it intact and further improving the accuracy of the sampled sediment data. Attached Figure Description

[0023] 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.

[0024] One embodiment of this utility model provides: a hydrological sediment collection device, such as... Figure 1 As shown, it includes a frame 1, a drive assembly 2, a collection mechanism 3, and a sediment collection and movement assembly 4.

[0025] like Figure 1 As shown, the frame 1 includes a base 11, a support base 12 and a support frame 13. The support base 12 is fixedly connected above the base 11, the support frame 13 is fixedly connected above the support base 12, and the drive assembly 2 is connected below the support frame 13 of the frame 1.

[0026] like Figure 2 and Figure 3As shown, the collection mechanism 3 is connected below the drive assembly 2. The drive assembly 2 includes a motor 21 and a first linear actuator 22. The first linear actuator 22 is rotatably connected to the frame 1 via the motor 21. The motor 21 is fixedly connected to the lower end of the support frame 13 of the frame 1. The output end of the first linear actuator 22 is fixedly connected to the output end of the motor 21. A connecting seat 221 is provided at the output end of the first linear actuator 22. When collecting sediment from the water body, the first linear actuator 22 of the drive assembly 2 drives the collection mechanism 3 to move downwards and into the water body. At the same time, the height of the collection mechanism 3 is adjusted according to the sediment at different heights in the water body. After sampling is completed, the first linear actuator 22 of the drive assembly 2 drives the collection mechanism 3 to move upwards with the sampled sediment back to the original position. The motor 21 of the drive assembly 2 drives the first linear actuator 22 to rotate, thereby separating or connecting the motor 22 with the collection mechanism 3.

[0027] The acquisition mechanism 3 is vertically slidably connected to the output end of the motor 21 below the support frame 13 via the first linear driver 22. The acquisition mechanism 3 includes a positioning seat 31, a connecting frame 32, a first side plate 33, a second linear driver 34, and a second side plate 35. The positioning seat 31 is connected to the connecting seat 221 at the output end of the first linear driver 22.

[0028] like Figure 4 As shown, for the structure of the positioning seat 31 and the connecting seat 221, an outer protrusion 2211 is provided on the periphery of the connecting seat 221, a slot 311 is opened on the upper part of the positioning seat 31, and an inner protrusion 312 is provided near the upper edge of the slot 311. The slot 311 matches the connecting seat 221. The outer diameter of the outer protrusion 2211 is smaller than the inner diameter of the slot 311 and larger than the inner diameter of the inner protrusion 312. The outer diameter of the connecting seat 221 is smaller than the inner diameter of the inner protrusion 312. The outer protrusion 2211 and the inner protrusion... The same number of 312 ring arrays are distributed. When the outer protrusion 2211 of the connecting seat 221 rotates to a position below the slot 311 where it is not the inner protrusion 312, the inner protrusion 312 will not limit the outer protrusion 2211, and the connecting seat 221 can be separated from the positioning seat 31. When the outer protrusion 2211 of the connecting seat 221 rotates to a position below the inner protrusion 312 of the slot 311, the inner protrusion 312 limits the outer protrusion 2211, and the connecting seat 221 and the positioning seat 31 are connected together.

[0029] like Figure 3As shown, the lower part of the positioning base 31 is fixedly connected to the connecting frame 32. Two first side plates 33 are fixed parallel to each other below the connecting frame 32. Positioning elements 331 are provided on opposite sides of the two first side plates 33. U-shaped grooves 3311 are provided on the positioning elements 331. The second side plate 35 is slidably connected between the two first side plates 33. The edge of the second side plate 35 is inserted into the U-shaped groove 3311. The second side plate 35 is made of flexible and bendable material. During the downward movement of the collection mechanism 3, the first side plate 33 is vertically inserted into the mud and sand in the water. The second side plate 35 also remains vertically inserted into the mud and sand. When the collection mechanism 3 stops at the height position to be sampled, the second side plate 35 slides to wrap the mud and sand in the bottom area of ​​the U-shaped groove 3311 between the first side plates 33. When the second side plate 35 slides to the bottom position of the U-shaped groove 3311, the second side plate 35 bends with the shape of the U-shaped groove 3311.

[0030] like Figure 4 and Figure 5 As shown, the optimal method is to arrange two second side plates 35 on the left and right sides of the U-shaped groove 3311, symmetrically distributed at both ends of the U-shaped groove 3311. The two second side plates 35 slide up and down within the U-shaped groove 3311 via a second linear actuator 34. The body of the second linear actuator 34 is fixed below the connecting frame 32, and the output end of the second linear actuator 34 is fixedly connected to the fixed connector 341. The upper ends of the two second side plates 35 are also fixedly connected to the fixed connector 341. The second linear actuator 34 drives the fixed connector 341 to simultaneously slide the two second side plates 35 downwards within the U-shaped groove 3311, moving them to the arc-shaped portion of the U-shaped groove 3311. The two second side plates 35 then bend and merge together, enveloping the mud and sand to be sampled in the upper region containing the first side plate 33. In its initial state, the second side plate 35 is vertically oriented. Together with the vertical structure of the first side plate 33, it makes the entire sampling mechanism 3 smoother when inserted into the sediment. It also reduces the disturbance to the sediment when the sampling mechanism 3 is inserted into the sediment, thereby improving the accuracy of the sediment sampling data. During the ascent of the sampling mechanism 3, the sediment wrapped at the top may be washed out. At the same time, the insertion depth of the sampling mechanism 3 depends on the position of the area to be sampled in the sediment. Therefore, the sediment wrapped at the bottom is the main sampling target. When the two second side plates 35 slide and deform and then fit together, the sediment at the bottom of the sampling package is effectively physically isolated, preventing the sediment at the bottom of the sampling package from falling off during the ascent in the water. This can protect the sediment at the bottom of the sampling package and may preserve it intact, thus improving the accuracy of the sediment sampling data.

[0031] like Figure 6As shown, each of the two second side plates 35 has a third inclined surface 351 at its closest end in the U-shaped groove 3311. When the two second side plates 35 are joined together in the U-shaped groove 3311, their respective third inclined surfaces 351 are joined together. The lower ends of both second side plates 35 have third inclined surfaces 351. On the one hand, when the two second side plates 35 are joined together, the structure at the connecting end increases the overlap, improving the isolation effect and further preventing the sediment at the lower end of the sampling area from falling off from the bottom. On the other hand, the lower end of the second side plate 35 has a small contact area with the sediment, making insertion into the sediment smoother and reducing disturbance to the sediment.

[0032] The lower end of the positioning member 331 is provided with a second inclined surface 3312, and the lower end of the first side plate 33 is provided with a first inclined surface 330, which extends from the second inclined surface 3312 of the positioning member 331. The first inclined surface 330 and the second inclined surface 3312 have the same inclination, and the upper end of the first inclined surface 330 is connected to the lower end of the second inclined surface 3312. The arrangement of the first inclined surface 330 and the second inclined surface 3312 on the first side plate 33 and the positioning member 331 also allows for smoother insertion into the mud and sand, while reducing disturbance to the mud and sand.

[0033] like Figure 2 and Figure 7 As shown, a sediment collection moving component 4 is provided on the side of the support base 12 of the frame 1. The sediment collection moving component 4 includes a support rod 41, a sliding member 42, and a support plug 44. The support rod 41 is fixedly connected to the support base 12 of the frame 1. The sliding member 42 is slidably connected below the support rod 41. The support plug 44 is located on the side of the sliding member 42 facing the first linear driver 22. The support plug 44 is plugged into and connected to the positioning seat 31. The side of the positioning seat 31 connected to the support plug 44 is provided with a cut-out snap-fit ​​surface 314. An outward protrusion 313 is provided above the snap-fit ​​surface 314 of the positioning seat 31.

[0034] A slide rail 411 is provided below the support rod 41, and a slider 421 is provided above the slider 42. The slider 421 is slidably connected to the slide rail 411. The sediment collection and movement component 4 also includes a third linear actuator 43. The body of the third linear actuator 43 is fixedly connected to the support base 12 of the frame 1, and the output end of the third linear actuator 43 is connected to the slider 42.

[0035] The sediment collection moving component 4, in conjunction with the motor 21 of the drive component 2, can separate the first linear actuator 22 from the sediment collection mechanism 3 after sediment sampling, and then pull the collection mechanism 3 back to the end operated by the operator. During this operation, the sediment collection mechanism 3 has moved upward to its original height. The third linear actuator 43 drives the slider 42 to move towards the first linear actuator 22. The support plug 44 on the slider 42 is inserted into the snap-fit ​​surface 314 below the outer protrusion 313 of the positioning seat 31. The motor 21 drives the first linear actuator 22 to rotate a certain angle. At the same time, the first linear actuator 22 drives the connecting seat 221 to move upward, separating the connecting seat 221 from the positioning seat 31. The connecting seat 221, along with the slider 42, is driven by the third linear actuator 43 to move towards the support seat 12, facilitating the removal of the sediment collection mechanism 3 and the separation of the sampled sediment. During the next sampling, the same operation is repeated. The slider 42 sends the collection mechanism 3 to below the first linear actuator 22 and connects it, and then it is lowered to insert into the sediment for sediment sampling. The connection between the sliding member 42 and the snap-fit ​​surface 314 limits the rotation direction of the positioning seat 31, preventing the positioning seat 31 from rotating with the connecting seat 221 when the motor 21 is working.

[0036] A connecting bracket 412 is provided on the side of the support rod 41 near the first linear actuator 22. The connecting bracket 412 is connected to the periphery of the body of the first linear actuator 22 via a bearing 4121. The connecting bracket 412 supports the body of the first linear actuator 22, improving the stability of the entire device during operation.
