Description
Technical Field
[0001] This invention relates to the field of testing equipment technology, specifically to a hydrological sediment content testing device. Background Technology
[0002] Hydrology is the science that studies the formation, cycle, movement, distribution, physicochemical properties, and interaction with the environment of water in nature. Its core is to reveal the natural laws governing water, providing fundamental data and theoretical support for water resource management and engineering practice. The hydrology industry belongs to the environmental protection industry, researching and solving water cycle processes, environmental engineering, environmental policy, and environmental planning; particularly studying sediments in rivers and reservoirs, river pollution, and urban drainage, involving both numerical and physical modeling. Sediment content is generally the mass of dry sand contained in a unit volume of turbid water. Sediment content detection equipment is required in hydrology to measure this content.
[0003] Currently, existing methods for detecting sediment content in water conservancy and hydrology involve fixed-position sediment detection equipment, making it inconvenient to adjust the depth of the equipment. This limits the detection to the same depth in the water body, resulting in overly simplistic detection methods, particularly affecting the accuracy of detecting suspended particles in the water. Summary of the Invention
[0004] To achieve the above objectives, the present invention provides the following technical solution: A hydrological sediment content detection device, comprising: A support base cylinder and a connecting clamp fixedly installed on the top of the inner side of the support base cylinder; a floating mechanism is fixedly installed on the surface of the support base cylinder. The testing mechanism is used to test the sediment content of water bodies at different depths in water conservancy and hydrology, and the testing mechanism is installed in the middle of the support base. The detection mechanism includes a hydraulic cylinder and a cylindrical sleeve. The hydraulic cylinder is fixedly connected to the surface of a connecting clamp via screws. The telescopic end of the hydraulic cylinder is fixedly installed to the top of the outer circular surface of the cylindrical sleeve. An elastic cleaning brush is fixedly connected to the side of the inner surface of the cylindrical sleeve. An arc-shaped flexible pad is fixedly connected to the inner surface of the cylindrical sleeve away from the elastic cleaning brush. A rectangular opening is provided in the middle of the outer circular surface of the cylindrical sleeve. An immersion photoelectric sand detector is fixedly installed at the bottom of the cylindrical sleeve. An auxiliary mechanism is fixedly installed on the top of the outer surface of the cylindrical sleeve. By contracting the extension end of the hydraulic cylinder, a downward pulling force can be applied to the cylindrical sleeve, causing it to pass through the center of the support base and move downward. The immersion photoelectric sand detector will be moved downward along with the cylindrical sleeve. The position of the immersion photoelectric sand detector can be adjusted by moving it downward, so that it can contact water at different depths, thereby conducting preliminary detection of the sand content in water at different depths.
[0005] Preferably, the hydraulic cylinders are installed vertically, and there are two hydraulic cylinders installed symmetrically along the cylindrical sleeve. The central axis of the cylindrical sleeve coincides with the central axis of the support base.
[0006] Preferably, the elastic cleaning brush is evenly distributed on the side of the inner surface of the cylindrical sleeve, and the elastic cleaning brush and the arc-shaped flexible pad are installed at the same height. There are two rectangular openings, and the two rectangular openings are symmetrically opened along the central axis of the cylindrical sleeve.
[0007] Preferably, the auxiliary mechanism includes a connecting collar, which is sleeved on the top of the outer circular surface of the cylindrical sleeve, and the connecting collar and the cylindrical sleeve are fixedly installed by screws. An arc-shaped plate is fixedly connected to the surface of the connecting collar, a divider is fixedly connected to the middle of the inner side of the arc-shaped plate, and a rectangular washer is fixedly connected to the inner side of the arc-shaped plate near the divider.
[0008] Preferably, there are four arc-shaped plates, and the four arc-shaped plates are evenly distributed on the surface of the connecting collar, and the rectangular washer is made of rubber.
[0009] Preferably, a sampling mechanism is installed inside the cylindrical sleeve. The sampling mechanism includes an annular support and a driver. The annular support is fixedly installed inside the cylindrical sleeve near the bottom. The driver is fixedly installed at the middle of the top of the cylindrical sleeve. A connecting shaft is rotatably installed at the middle of the top of the inner cavity of the cylindrical sleeve. A sample storage cylinder is rotatably installed at the center of the annular support. The bottom end of the connecting shaft is fixedly installed to the top of the sample storage cylinder. A conical feed hopper is installed at the middle of the outer surface of the sample storage cylinder. A circular partition is fixedly installed inside the inner cavity of the sample storage cylinder. The outer surface of the sample storage cylinder is far from... A sealing plug is detachably installed on one side of the conical feed hopper. As the cylindrical sleeve moves downward, the entire sampling mechanism is driven downward as well. The rotation of the drive output can drive the connecting shaft to rotate, and with the support of the rotating ring bracket, the sample storage cylinder is driven by the connecting shaft to rotate smoothly. Through the continuous rotation of the sample storage cylinder, when the conical feed hopper rotates to the position of the rectangular opening, the water carrying suspended sediment enters the interior of the sample storage cylinder from the conical feed hopper. By keeping the sample storage cylinder in a dynamic state, it promotes the uniform entry of the water carrying suspended sediment into the sample storage cylinder, which helps to accurately sample the water.
[0010] Preferably, the top end of the connecting shaft penetrates the top of the inner cavity of the cylindrical sleeve and extends to its outside. The top end of the connecting shaft is fixedly installed to the output end of the driver via a coupling. The central axis of the middle of the sample storage cylinder coincides with the central axis of the middle of the cylindrical sleeve. The driver, connecting shaft, and sample storage cylinder are installed on the same vertical line. The conical feed hopper is evenly distributed along the vertical direction of the sample storage cylinder, allowing multiple sets of sample storage cylinders to sample water and sediment at different depths. The circular partitions separate the sampled water and sediment at different locations inside the sample storage cylinder, facilitating the orderly and accurate analysis of sediment content at different depths of water. The multi-location sampling method makes the detection of sediment content in water conservancy and hydrology more accurate.
[0011] Preferably, there are four conical feed hoppers, which are evenly distributed in the middle of the outer circumference of the sample storage cylinder. There are also four circular partitions, which are evenly distributed in the inner cavity of the sample storage cylinder. As the sample storage cylinder rotates, the conical feed hoppers are driven to rotate as well. The liquid inlet of the conical feed hopper contacts the curved flexible pad, which wipes away the mud and sand adhering to the liquid inlet. As the conical feed hopper continues to rotate, the liquid inlet of the conical feed hopper contacts the elastic cleaning brush, which cleans away the mud and sand adhering to the liquid inlet, reducing the impact of mud and sand adhesion and preventing clogging. This further promotes the sampling of water and mud.
[0012] After sampling is completed in the sample storage cylinder, the conical feed hopper is rotated by the sample storage cylinder. The liquid inlet of the conical feed hopper is then brought into contact with the curved flexible pad, and the drive is paused. This causes the liquid inlet of the conical feed hopper to squeeze the curved flexible pad. Through action and reaction forces, the curved flexible pad seals the liquid inlet of the conical feed hopper, reducing the impact of shaking. The water and sediment collected in the sample storage cylinder will not flow out, thus effectively preserving the sample.
[0013] Preferably, the floating mechanism includes a floating airbag and a conical guide ring. The floating airbag is sleeved on the outer circular surface of the supporting base cylinder, and the inner side of the floating airbag is fixedly installed with the surface of the supporting base cylinder. The conical guide ring is fixedly installed at the top edge of the supporting base cylinder, and an annular guide extension plate is fixedly connected to the top of the conical guide ring. A rectangular through hole is opened in the middle of the surface of the annular guide extension plate. An elastic protective net is fixedly installed on the surface of the floating airbag. As the extension end of the hydraulic cylinder contracts, it drives the cylindrical sleeve to move downward, causing the auxiliary mechanism to move downward as a whole. By inserting the divider into the rectangular through hole, it can play a limiting role. The rectangular washer is located between the arc plate and the annular guide extension plate. The rectangular washer is squeezed, so that the arc plate and the annular guide extension plate make flexible contact.
[0014] By having the floating airbags contact the water surface, the supporting base cylinder is floated and supported by buoyancy, preventing the testing mechanism from sinking to the bottom. In addition, the elastic protective netting wraps around the surface of the floating airbags, protecting them from scratches.
[0015] Preferably, the floating airbag, conical drainage ring, annular flow guide extension plate, and support base are concentric circles, and there are four rectangular through holes, which are evenly distributed on the surface of the annular flow guide extension plate. When the wind and waves impact, the elastic protective net comes into contact with the wind and waves, and the square mesh of the elastic protective net divides the wind and waves, thus dispersing and weakening the impact force of the wind and waves, which can provide initial treatment of the wind and waves impact. Under the guidance of the conical drainage ring, the wind and waves are caused to curl and flow around the arc surface of the inner side of the annular flow guide extension plate, which can guide the wind and waves and reduce the frontal impact of the wind and waves. At the same time, the divider divides the wind and waves guided by the annular flow guide extension plate, further reducing the impact force of the wind and waves, making the support base, detection mechanism, and sampling mechanism more stable as a whole and reducing the sway amplitude.
[0016] This invention provides a hydrological sediment content detection device. It has the following beneficial effects: I. This hydrological sediment content detection equipment utilizes the telescopic end of a hydraulic cylinder to pull a cylindrical sleeve downwards, causing the cylindrical sleeve to pass through the center of the supporting base and move downwards. The immersion photoelectric sediment detector is pulled downwards along with the cylindrical sleeve, allowing the position of the immersion photoelectric sediment detector to be adjusted so that it contacts water at different depths, thereby enabling preliminary detection of sediment content in water at different depths.
[0017] II. This hydrological sediment content detection equipment utilizes the rotation of the driver output to drive the connecting shaft to rotate. Under the rotational support of the annular bracket, the sample storage cylinder is driven by the connecting shaft to rotate smoothly. Through the continuous rotation of the sample storage cylinder, when the conical feed hopper rotates to the position of the rectangular opening, the water carrying suspended sediment enters the interior of the sample storage cylinder from the conical feed hopper. By utilizing the fact that the sample storage cylinder is always in motion, it promotes the uniform entry of water carrying suspended sediment into the sample storage cylinder, which helps to accurately sample the water.
[0018] Third, this hydrological sediment content detection equipment uses a conical feed hopper evenly distributed along the vertical direction of the sample storage cylinder. Multiple sample storage cylinders can be used to sample water and sediment at different depths. The circular partitions separate the water and sediment samples from different depths, allowing for orderly and accurate analysis of sediment content at different depths. The multi-location sampling method makes the detection of hydrological sediment content more accurate.
[0019] IV. This hydrological sediment content detection equipment uses a conical feed hopper with a flexible arc-shaped pad in contact with the feed inlet. The flexible arc-shaped pad wipes away the sediment adhering to the feed inlet. As the conical feed hopper rotates, the feed inlet comes into contact with an elastic cleaning brush, which cleans away the sediment and debris adhering to the feed inlet. This reduces the impact of sediment adhesion, prevents clogging, and further facilitates the sampling of water and sediment.
[0020] V. In this hydrological sediment content detection equipment, after sampling is completed in the sample storage cylinder, the sample storage cylinder drives the conical feed hopper to rotate. The liquid inlet of the conical feed hopper fits into the curved flexible pad, causing the liquid inlet of the conical feed hopper to squeeze the curved flexible pad. Using action and reaction forces, the curved flexible pad seals the liquid inlet of the conical feed hopper, thus reducing the impact of shaking. The water and sediment collected in the sample storage cylinder will not flow out, effectively preserving the sample.
[0021] VI. In this hydrological sediment content detection equipment, as the hydraulic cylinder retracts, it drives the cylindrical sleeve to move downwards, causing the auxiliary mechanism to move downwards as a whole. By inserting the divider into the rectangular through hole, it can play a limiting role. The rectangular washer is located between the arc plate and the annular guide extension plate. The rectangular washer is compressed, causing the arc plate and the annular guide extension plate to make flexible contact, which can stably support the cylindrical sleeve, making the detection mechanism more stable as a whole.
[0022] VII. This hydrological sediment content detection equipment uses floating airbags to contact the water surface. Under the action of buoyancy, the supporting base is floated and supported, so that the detection mechanism will not sink to the bottom of the water. In addition, the elastic protective net is wrapped around the surface of the floating airbags to protect them and prevent them from being scratched.
[0023] 8. This hydrological sediment content detection equipment utilizes the square mesh of an elastic protective net to divide the waves, thereby dispersing and weakening their impact. This provides initial treatment of the wave impact. Under the guidance of the conical diversion ring, the waves are guided to flow around the arc surface of the inner side of the annular guide extension plate, thus reducing the frontal impact of the waves. At the same time, the divider further divides the waves guided by the annular guide extension plate, further reducing the impact of the waves. This makes the support base, detection mechanism, and sampling mechanism more stable as a whole, reducing the amplitude of swaying. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution: A hydrological sediment content detection device, comprising: Support base 1, and connecting clamp 2 fixedly installed on the top of the inner side of support base 1; floating mechanism 3 is fixedly installed on the surface of support base 1. Testing mechanism 4 is used to test the sediment content of water bodies at different depths in water conservancy and hydrology. Testing mechanism 4 is installed in the middle of the support base cylinder 1. The detection mechanism 4 includes a hydraulic cylinder 41 and a cylindrical sleeve 42. The hydraulic cylinder 41 is fixedly connected to the surface of the connecting clamp 2 by screws. The telescopic end of the hydraulic cylinder 41 is fixedly installed on the top of the outer circular surface of the cylindrical sleeve 42. An elastic cleaning brush 43 is fixedly connected to the side of the inner side of the cylindrical sleeve 42. An arc-shaped flexible pad 44 is fixedly connected to the inner side of the cylindrical sleeve 42 away from the elastic cleaning brush 43. A rectangular opening 45 is opened in the middle of the outer circular surface of the cylindrical sleeve 42. An immersion photoelectric sand detector 46 is fixedly installed at the bottom of the cylindrical sleeve 42. An auxiliary mechanism 47 is fixedly installed on the top of the circular surface. When the operator starts the hydraulic cylinder 41, the contraction of the extension end of the hydraulic cylinder 41 can apply a downward pulling force to the cylindrical sleeve 42, so that the cylindrical sleeve 42 passes through the center of the support base cylinder 1 and moves downward. The immersion photoelectric sand detector 46 will be driven downward by the cylindrical sleeve 42. The position of the immersion photoelectric sand detector 46 can be adjusted by moving it downward, so that the immersion photoelectric sand detector 46 can contact the water body at different depths and make preliminary detection of the sand content of the water body at different depths.
[0028] The hydraulic cylinder 41 is installed vertically. There are two hydraulic cylinders 41, and the two hydraulic cylinders 41 are symmetrically installed along the cylindrical sleeve 42. The central axis of the cylindrical sleeve 42 coincides with the central axis of the support base cylinder 1.
[0029] The elastic cleaning brushes 43 are evenly distributed on the sides of the inner side of the cylindrical sleeve 42, and the elastic cleaning brushes 43 and the curved flexible pad 44 are installed at the same height. There are two rectangular openings 45, and the two rectangular openings 45 are symmetrically opened along the central axis of the cylindrical sleeve 42.
[0030] The auxiliary mechanism 47 includes a connecting collar 471, which is sleeved on the top of the outer circular surface of the cylindrical sleeve 42 and is fixedly installed between the connecting collar 471 and the cylindrical sleeve 42 by screws. An arc-shaped plate 472 is fixedly connected to the surface of the connecting collar 471. A divider 473 is fixedly connected to the middle of the inner side of the arc-shaped plate 472. A rectangular washer 474 is fixedly connected to the inner side of the arc-shaped plate 472 near the divider 473.
[0031] There are four arc-shaped plates 472, and the four arc-shaped plates 472 are evenly distributed on the surface of the connecting collar 471. The rectangular washer 474 is made of rubber.
[0032] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 8 As shown: A sampling mechanism 5 is installed inside the cylindrical sleeve 42. The sampling mechanism 5 includes an annular support 51 and a driver 52. The annular support 51 is fixedly installed inside the cylindrical sleeve 42 near the bottom. The driver 52 is fixedly installed at the middle of the top of the cylindrical sleeve 42. A connecting shaft 53 is rotatably installed at the middle of the top of the inner cavity of the cylindrical sleeve 42. A sample storage cylinder 54 is rotatably installed at the center of the annular support 51. The bottom end of the connecting shaft 53 is fixedly installed to the top of the sample storage cylinder 54. A conical feed hopper 55 is installed at the middle of the outer surface of the sample storage cylinder 54. A circular partition 56 is fixedly installed in the inner cavity of the sample storage cylinder 54. The outer surface of the sample storage cylinder 54 away from the conical feed hopper 55 is detachably installed. With the sealing plug 57, as the cylindrical sleeve 42 moves downward, the sampling mechanism 5 is driven to move downward as well. When the sample storage cylinder 54 moves to the designated position in the water body, the driver 52 is turned on to work. The rotation of the output end of the driver 52 can drive the connecting shaft 53 to rotate. Under the rotation support of the annular bracket 51, the sample storage cylinder 54 is driven by the connecting shaft 53 to rotate smoothly. Through the continuous rotation of the sample storage cylinder 54, when the conical feed hopper 55 rotates to the position of the rectangular opening 45, the water body carrying suspended sediment enters the interior of the sample storage cylinder 54 from the conical feed hopper 55. By using the fact that the sample storage cylinder 54 is always in motion, it promotes the water body carrying suspended sediment to enter the sample storage cylinder 54 evenly.
[0033] The top end of the connecting shaft 53 passes through the top of the inner cavity of the cylindrical sleeve 42 and extends to its outside. The top end of the connecting shaft 53 is fixedly installed with the output end of the driver 52 through a coupling. The central axis of the sample storage cylinder 54 in the middle coincides with the central axis of the cylindrical sleeve 42 in the middle. The driver 52, the connecting shaft 53 and the sample storage cylinder 54 are installed on the same vertical line.
[0034] By uniformly distributing the conical feed hopper 55 along the vertical direction of the sample storage cylinder 54, water and sediment at different depths can be sampled through multiple sets of sample storage cylinders 54. Furthermore, the circular partition 56 ensures that the water and sediment samples at different depths are stored in different locations inside the sample storage cylinder 54.
[0035] There are four conical feed hoppers 55, which are evenly distributed in the middle of the outer surface of the sample storage cylinder 54. There are also four circular baffles 56, which are evenly distributed in the inner cavity of the sample storage cylinder 54. As the sample storage cylinder 54 rotates, the conical feed hoppers 55 are driven to rotate together. The liquid inlet of the conical feed hopper 55 comes into contact with the arc-shaped flexible pad 44, which wipes away the mud and sand adhering to the liquid inlet of the conical feed hopper 55. As the conical feed hopper 55 continues to rotate, the liquid inlet of the conical feed hopper 55 comes into contact with the elastic cleaning brush 43, which cleans the mud and sand adhering to the liquid inlet of the conical feed hopper 55.
[0036] After sampling is completed in the sample storage cylinder 54, the sample storage cylinder 54 drives the conical feed hopper 55 to rotate. The liquid inlet of the conical feed hopper 55 is brought into contact with the arc-shaped flexible pad 44, and the operation of the driver 52 is paused. This causes the liquid inlet of the conical feed hopper 55 to squeeze the arc-shaped flexible pad 44. Using action and reaction forces, the arc-shaped flexible pad 44 seals the liquid inlet of the conical feed hopper 55, reducing the impact of shaking. The water and sediment collected in the sample storage cylinder 54 will not flow out.
[0037] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 1 to 9 As shown: The floating mechanism 3 includes a floating airbag 31 and a conical flow guide ring 32. The floating airbag 31 is sleeved on the outer circular surface of the support base cylinder 1, and the inner side of the floating airbag 31 is fixedly installed with the surface of the support base cylinder 1. The conical flow guide ring 32 is fixedly installed at the top edge of the support base cylinder 1. An annular flow guide extension plate 33 is fixedly connected to the top of the conical flow guide ring 32. A rectangular through hole 34 is opened in the middle of the surface of the annular flow guide extension plate 33. An elastic protective net 35 is fixedly installed on the surface of the floating airbag 31. As the extension end of the hydraulic cylinder 41 contracts, it drives the cylindrical sleeve 42 to move downward, causing the auxiliary mechanism 47 to move downward as a whole. By inserting the divider 473 into the rectangular through hole 34, it can play a limiting role. The rectangular washer 474 is located between the arc plate 472 and the annular flow guide extension plate 33. The rectangular washer 474 is squeezed, so that the arc plate 472 and the annular flow guide extension plate 33 make flexible contact.
[0038] By having the floating airbag 31 come into contact with the water surface, the supporting base cylinder 1 is supported by buoyancy, so that the detection mechanism 4 will not sink to the bottom of the water. The elastic protective net 35 wraps around the surface of the floating airbag 31, protecting the floating airbag 31 and making it less likely to be scratched.
[0039] The floating airbag 31, the conical drainage ring 32, the annular flow guide extension plate 33, and the support base 1 are concentric circles. There are four rectangular through holes 34, which are evenly distributed on the surface of the annular flow guide extension plate 33. When the wind and waves impact, the elastic protective net 35 comes into contact with the wind and waves. The square mesh of the elastic protective net 35 divides the wind and waves, so that the impact force of the wind and waves is dispersed and weakened, thus providing initial treatment for the impact of the wind and waves. Under the guidance of the conical drainage ring 32, the wind and waves are caused to curl and flow around the arc surface of the inner side of the annular flow guide extension plate 33, which can guide the wind and waves and reduce the frontal impact of the wind and waves. At the same time, the divider 473 divides the wind and waves guided by the annular flow guide extension plate 33, further reducing the impact force of the wind and waves, making the support base 1, the detection mechanism 4, and the sampling mechanism 5 more stable as a whole and reducing the swaying amplitude.
[0040] When in use, the entire device is first placed in the water body to be tested. The floating airbag 31 contacts the water surface and, under the action of buoyancy, supports the support base cylinder 1, so that the testing mechanism 4 will not sink to the bottom of the water. The elastic protective net 35 wraps around the surface of the floating airbag 31 to protect the floating airbag 31, making the floating airbag 31 less likely to be scratched. Furthermore, when the operator starts the hydraulic cylinder 41, the contraction of the telescopic end of the hydraulic cylinder 41 can apply a downward pulling force to the cylindrical sleeve 42, causing the cylindrical sleeve 42 to pass through the center of the support base cylinder 1 and move downward. By inserting the divider 473 into the rectangular through hole 34, it can play a limiting role. The rectangular washer 474 is located between the arc plate 472 and the annular guide extension plate 33. The rectangular washer 474 is squeezed, which makes the arc plate 472 and the annular guide extension plate 33 make flexible contact, making the overall equipment more stable. Furthermore, the immersion photoelectric sand detector 46 will be driven downward by the cylindrical sleeve 42, so that the position of the immersion photoelectric sand detector 46 can be adjusted by moving the immersion photoelectric sand detector 46 downward, so that the immersion photoelectric sand detector 46 can contact water at different depths and make preliminary detection of the sand content of water at different depths. Simultaneously, as the cylindrical sleeve 42 moves downward, the sampling mechanism 5 is driven to move downward as well. When the sample storage cylinder 54 moves to the designated position in the water body, the driver 52 is activated. The rotation of the output end of the driver 52 can drive the connecting shaft 53 to rotate. Under the rotational support of the annular bracket 51, the sample storage cylinder 54 is driven to rotate smoothly by the connecting shaft 53. Through the continuous rotation of the sample storage cylinder 54, when the conical feed hopper 55 rotates to the position of the rectangular opening 45, the water body carrying suspended sediment enters the interior of the sample storage cylinder 54 from the conical feed hopper 55. By utilizing the fact that the sample storage cylinder 54 is always in motion, it promotes the uniform entry of the water body carrying suspended sediment into the sample storage cylinder 54. By evenly distributing the conical feed hopper 55 along the vertical direction of the sample storage cylinder 54, water and sediment at different depths can be sampled through multiple sets of sample storage cylinders 54. Furthermore, the circular partition 56 ensures that the water and sediment samples at different depths are stored in different locations inside the sample storage cylinder 54. Furthermore, as the sample storage cylinder 54 rotates, the conical feed hopper 55 is driven to rotate as well. The liquid inlet of the conical feed hopper 55 comes into contact with the arc-shaped flexible pad 44, which wipes away the mud and sand adhering to the liquid inlet of the conical feed hopper 55. As the conical feed hopper 55 continues to rotate, the liquid inlet of the conical feed hopper 55 comes into contact with the elastic cleaning brush 43, which cleans away the mud and sand adhering to the liquid inlet of the conical feed hopper 55. After sampling is completed in the sample storage cylinder 54, the sample storage cylinder 54 drives the conical feed hopper 55 to rotate. The liquid inlet of the conical feed hopper 55 is brought into contact with the arc-shaped flexible pad 44, and the operation of the driver 52 is paused. This causes the liquid inlet of the conical feed hopper 55 to squeeze the arc-shaped flexible pad 44. Using action and reaction forces, the arc-shaped flexible pad 44 seals the liquid inlet of the conical feed hopper 55, reducing the impact of shaking. The water and sediment collected in the sample storage cylinder 54 will not flow out. Moreover, when the wind and waves impact, the elastic protective net 35 comes into contact with the wind and waves. The square mesh of the elastic protective net 35 divides the wind and waves, thus dispersing and weakening the impact force of the wind and waves. This can provide initial treatment for the impact of the wind and waves. Under the guidance of the conical flow guide ring 32, the wind and waves are caused to curl and flow around the arc surface of the inner side of the annular flow guide extension plate 33, which can guide the wind and waves and reduce the frontal impact of the wind and waves. At the same time, the divider 473 divides the wind and waves guided by the annular flow guide extension plate 33, further reducing the impact force of the wind and waves. This makes the support base cylinder 1, the detection mechanism 4 and the sampling mechanism 5 more stable as a whole, reducing the sway amplitude. Once sampling is complete, the hydraulic cylinder 41 can be activated again. By extending the telescopic end of the hydraulic cylinder 41, the cylindrical sleeve 42 is pushed upwards and moved, causing the entire sampling mechanism 5 to move upwards. Then, the sealing plug 57 can be removed to take out the sample from the sample storage cylinder 54 for further analysis and testing.
