Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, in particular to a water conservancy and hydrology sediment content detection device. Background Art

[0002] Water conservancy and hydrology is the science that studies the formation, circulation, movement, distribution, physical and chemical properties of water in nature, and its interaction with the environment. Its core objective is to reveal the natural laws of water and provide fundamental data and theoretical support for water resources management and engineering practices. The water conservancy and hydrology industry, part of the environmental protection sector, studies and addresses water cycle processes, environmental engineering, environmental policy, and environmental planning. It particularly focuses on the sedimentation of rivers and reservoirs, river pollution, and urban drainage, using both numerical and physical models. Sediment content is generally measured as the mass of dry sand per unit volume of turbid water. Sediment content testing equipment is essential for water conservancy and hydrology.

[0003] At present, in the existing water conservancy and hydrological sediment content detection, the position of the sediment content detection equipment is fixed, which makes it inconvenient to adjust the depth of the sediment content detection equipment. It can only be tested at the same depth of the water body, resulting in overly single detection, especially for the detection of suspended particles in the water body, affecting the accuracy of the detection. Summary of the Invention

The hydraulic cylinder is fixedly connected to the surface of the connecting caliper by screws. The telescopic end of the hydraulic cylinder is fixedly installed on the top of the outer surface of the cylindrical sleeve. An elastic cleaning brush is fixedly connected to the side of the inner surface of the cylindrical sleeve. A curved flexible pad is fixedly connected to the inner surface of the cylindrical sleeve and the side away from the elastic cleaning brush. A rectangular opening is opened in the middle of the outer surface of the cylindrical sleeve. An immersion photoelectric sand detector is fixedly installed on 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 telescopic end of the hydraulic cylinder, a downward pulling force can be applied to the cylindrical sleeve, so that the cylindrical sleeve passes through the center of the supporting base and moves downward. The immersive photoelectric sand detector will be driven downward by the cylindrical sleeve. The immersive photoelectric sand detector can be moved downward and the position of the immersive photoelectric sand detector can be adjusted so that the immersive photoelectric sand detector comes into contact with water bodies of different depths, thereby performing preliminary detection of the sand content in water bodies of different depths.

[0005] Preferably, the hydraulic cylinder is installed vertically, there are two hydraulic cylinders, and the two hydraulic cylinders are installed symmetrically along the cylindrical sleeve, and the central axis in the middle of the cylindrical sleeve coincides with the central axis in the middle of the supporting base tube.

[0006] Preferably, the elastic cleaning brushes are evenly distributed on the sides of the inner side of the cylindrical sleeve, and the elastic cleaning brushes and the curved 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 ring, which is sleeved on the top of the outer surface of the cylindrical sleeve, and the connecting ring and the cylindrical sleeve are fixed by screws. The surface of the connecting ring is fixedly connected to an arc plate, the middle of the inner side of the arc plate is fixedly connected to a divider, and the inner side of the arc plate and the position close to the divider are fixedly connected to a rectangular washer.

[0008] Preferably, there are four arc-shaped plates, and the four arc-shaped plates are evenly distributed on the surface of the connecting ring, and the rectangular gasket is made of rubber.

[0009] Preferably, a sampling mechanism is installed inside the cylindrical sleeve, and the sampling mechanism includes an annular bracket and a driver, the annular bracket is fixedly installed inside the cylindrical sleeve and close to the bottom, the driver is fixedly installed in the middle of the top of the cylindrical sleeve, a connecting shaft is rotatably installed in 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 bracket, the bottom end of the connecting shaft is fixedly installed to the top of the sample storage cylinder, a conical feed hopper is installed in the middle of the outer circumference of the sample storage cylinder, a circular partition is fixedly installed in the inner cavity of the sample storage cylinder, and the outer circumference of the sample storage cylinder is far away. A sealing plug is detachably installed on one side of the conical feed hopper. As the cylindrical sleeve moves downward, the sampling mechanism as a whole is driven downward. The rotation of the output end of the driver can drive the connecting shaft to rotate, and under the rotation 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 mouth, the water body carries suspended sediment from the conical feed hopper into the interior of the sample storage cylinder. The sample storage cylinder is always in motion, which promotes the water body to carry suspended sediment into the sample storage cylinder evenly, which helps to accurately sample the water body.

[0010] Preferably, the top end of the connecting shaft passes through the top of the inner cavity of the cylindrical sleeve and extends to the outside thereof, and the top end of the connecting shaft is fixedly installed with the output end of the driver through a coupling, and 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, and are evenly distributed along the vertical direction of the sample storage cylinder through the conical feed hopper. Water bodies and sediments at different depths can be sampled through multiple groups of sample storage cylinders, and the circular partition is used to block the different water bodies and sediments sampled, so that different positions inside the sample storage cylinder are stored, thereby facilitating orderly and accurate analysis of the sediment content at different depths of the water body. The multi-position sampling method is adopted to make the detection of water conservancy and hydrological sediment content more accurate.

[0011] Preferably, there are four conical feed hoppers, and the four conical feed hoppers are evenly distributed in the middle of the outer cylindrical surface of the sample storage cylinder. There are four circular partitions, and the four circular partitions are evenly distributed in the inner cavity of the sample storage cylinder. As the sample storage cylinder rotates, the conical feed hopper is driven to rotate together, and the liquid inlet of the conical feed hopper contacts the curved flexible pad, and the curved flexible pad wipes the mud and sand sticking to the liquid inlet of the conical feed hopper. As the conical feed hopper continues to rotate, the liquid inlet of the conical feed hopper contacts the elastic cleaning brush, and the elastic cleaning brush can be used to clean the mud and sand debris sticking to the liquid inlet of the conical feed hopper, reducing the impact of mud and sand adhesion, making it less likely to be blocked, and further promoting the sampling of water and mud.

[0012] When sampling in the sample storage cylinder is completed, the conical feed hopper is driven to rotate by the sample storage cylinder, and the liquid inlet of the conical feed hopper is fitted with the curved flexible pad, and the driver is paused, so that the liquid inlet of the conical feed hopper squeezes the curved flexible pad, and the curved flexible pad uses the action force and reaction force to seal the liquid inlet of the conical feed hopper, which can reduce the impact of shaking, and the water and sediment collected in the sample storage cylinder will not flow out, so the sample can be effectively preserved.

[0013] Preferably, the floating mechanism includes a floating airbag and a conical drainage ring, the floating airbag is sleeved on the outer circular surface of the supporting base tube, and the inner side surface of the floating airbag is fixedly installed on the surface of the supporting base tube, the conical drainage ring is fixedly installed at the edge of the top of the supporting base tube, the top of the conical drainage ring is fixedly connected to an annular guide extension piece, a rectangular through hole is opened in the middle of the surface of the annular guide extension piece, and an elastic protective net is fixedly installed on the surface of the floating airbag, and as the telescopic end of the hydraulic cylinder contracts, the cylindrical sleeve is driven to move downward, so that the auxiliary mechanism moves downward as a whole, and the divider is inserted into the inside of the rectangular through hole to play a limiting role, and the rectangular gasket is located between the arc plate and the annular guide extension piece, and the rectangular gasket is squeezed, so that the arc plate and the annular guide extension piece are in flexible contact.

[0014] The floating airbag is in contact with the water surface, and the supporting base tube is floated and supported under the action of buoyancy, so that the detection mechanism will not sink to the bottom of the water. The elastic protective net is wrapped around the surface of the floating airbag to protect the floating airbag, and the floating airbag is not easily scratched.

[0015] Preferably, the floating airbag, conical drainage ring, annular guide extension piece and supporting base tube are concentric circles, and there are four rectangular through holes, and the four rectangular through holes are evenly distributed on the surface of the annular guide extension piece. When wind and waves hit, the elastic protective net contacts the wind and waves, and the grid-shaped mesh of the elastic protective net is used to divide the wind and waves, so that the impact force of the wind and waves is dispersed and weakened, so that the impact of the wind and waves can be preliminarily processed, and under the drainage of the conical drainage ring, the wind and waves are curled and circulated along the arc surface of the inner side of the annular guide extension piece, so that the wind and waves can be guided and the frontal impact of the wind and waves is weakened. At the same time, the divider divides the wind and waves guided by the annular guide extension piece, and further weakens the impact force of the wind and waves, so that the supporting base tube, the detection mechanism and the sampling mechanism are more stable as a whole, and the shaking amplitude is reduced.

[0016] The present invention provides a water conservancy and hydrological sediment content detection device. It has the following beneficial effects: 1. This water conservancy and hydrological sediment content detection equipment uses the telescopic end of the hydraulic cylinder to pull the cylindrical sleeve downward, so that the cylindrical sleeve passes through the center of the supporting base and moves downward. The immersive photoelectric sand detector will be driven downward by the cylindrical sleeve. The position of the immersive photoelectric sand detector can be adjusted by moving the immersive photoelectric sand detector downward, so that the immersive photoelectric sand detector contacts water bodies at different depths, thereby performing preliminary detection of the sediment content of water bodies at different depths.

[0017] 2. The water conservancy and hydrological sediment content detection equipment utilizes the rotation of the driver output end to drive the connecting shaft to rotate, and under the rotation support of the annular bracket, the sample storage tube is driven by the connecting shaft to rotate smoothly. Through the continuous rotation of the sample storage tube, when the conical feed hopper rotates to the position of the rectangular mouth, the water body carries the suspended sediment from the conical feed hopper into the interior of the sample storage tube. The sample storage tube is always in motion, which promotes the water body to carry the suspended sediment into the sample storage tube evenly, and helps to accurately sample the water body.

[0018] 3. The water conservancy and hydrological sediment content detection equipment can sample water and sediment at different depths through multiple groups of sample storage tubes through the conical feed hopper evenly distributed along the vertical direction of the sample storage tube, and use the circular partition to make the sampled water and sediment at different depths stored in different positions inside the sample storage tube, thereby facilitating the orderly and accurate analysis of the sediment content at different depths of the water body. The multi-position sampling method is adopted to make the water conservancy and hydrological sediment content detection more accurate.

[0019] 4. The water conservancy and hydrological sediment content detection equipment contacts the curved flexible pad through the liquid inlet of the conical feed hopper. The curved flexible pad will wipe the sticky sediment at the liquid inlet of the conical feed hopper. As the conical feed hopper continues to rotate, the liquid inlet of the conical feed hopper contacts the elastic cleaning brush, which can clean the sticky sediment and debris at the liquid inlet of the conical feed hopper through the elastic cleaning brush, reducing the impact of sediment attachment, making it less likely to be blocked, and further promoting the sampling of water and sediment.

[0020] 5. After the sampling in the sample storage cylinder is completed, the water conservancy and hydrological sediment content detection equipment drives the conical feed hopper to rotate through the sample storage cylinder, and utilizes the liquid inlet of the conical feed hopper to fit with the curved flexible pad, so that the liquid inlet of the conical feed hopper squeezes the curved flexible pad, and utilizes the action force and reaction force to make the curved flexible pad seal the liquid inlet of the conical feed hopper, thereby reducing the impact of shaking, and the water and sediment collected in the sample storage cylinder will not flow out, so the sample is effectively preserved.

[0021] 6. As the telescopic end of the hydraulic cylinder contracts, the water conservancy and hydrological sediment content detection equipment drives the cylindrical sleeve to move downward, causing the auxiliary mechanism to move downward as a whole. The divider is inserted into the interior of the rectangular through-hole to play a limiting role. The rectangular washer is located between the arc plate and the annular guide extension piece. The rectangular washer is squeezed, causing the arc plate and the annular guide extension piece to make flexible contact, which can provide stable support for the cylindrical sleeve, making the detection mechanism more stable as a whole.

[0022] 7. This water conservancy and hydrological sediment content detection equipment contacts the water surface through a floating airbag. Under the action of buoyancy, the supporting base tube is floated and supported, so that the detection mechanism will not sink to the bottom of the water. The elastic protective net is wrapped around the surface of the floating airbag to protect the floating airbag, making it not easily scratched.

[0023] 8. This water conservancy and hydrological sediment content detection equipment uses the grid-shaped mesh of the elastic protective net to divide the wind and waves, so that the impact force of the wind and waves is dispersed and weakened, which can provide preliminary treatment for the impact of the wind and waves. Under the drainage of the conical drainage ring, the wind and waves are curled and flowed along the arc surface of the inner side of the annular diversion extension piece, which can divert the wind and waves and weaken the frontal impact of the wind and waves. At the same time, the divider divides the wind and waves diverted by the annular diversion extension piece, further weakening the impact force of the wind and waves, making the supporting base tube, detection mechanism and sampling mechanism more stable as a whole and reducing the shaking amplitude.

[0032] The second embodiment, based on the first embodiment, see Figures 1 to 8 As shown: A sampling mechanism 5 is installed inside the cylindrical sleeve 42. The sampling mechanism 5 includes an annular bracket 51 and a driver 52. The annular bracket 51 is fixedly installed inside the cylindrical sleeve 42 and near the bottom. The driver 52 is fixedly installed in the middle of the top of the cylindrical sleeve 42. A connecting shaft 53 is rotatably installed in 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 bracket 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 in the middle of the outer circumference 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 circumference of the sample storage cylinder 54 and the side away from the conical feed hopper 55 are detachably installed. There is a sealing plug 57. As the cylindrical sleeve 42 moves downward, the sampling mechanism 5 is driven to move downward as a whole. When the sample storage cylinder 54 moves to the specified 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, and 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 mouth 45, the water body carries suspended sediment from the conical feed hopper 55 into the interior of the sample storage cylinder 54. The sample storage cylinder 54 is always in motion, which promotes the water body to carry suspended sediment into 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 the outside thereof, and 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 middle of the sample storage cylinder 54 coincides with the central axis of the middle of the cylindrical sleeve 42, and the driver 52, the connecting shaft 53 and the sample storage cylinder 54 are installed on the same vertical line.

[0034] By evenly distributing the conical feed hoppers 55 along the vertical direction of the sample storage cylinder 54 , water and sediment at different depths can be sampled through multiple groups of sample storage cylinders 54 , and by utilizing the circular partitions 56 , the sampled water and sediment at different depths can be stored at different positions inside the sample storage cylinder 54 .

[0035] There are four conical feed hoppers 55, and the four conical feed hoppers 55 are evenly distributed in the middle of the outer surface of the sample storage cylinder 54. There are four circular partitions 56, and the four circular partitions 56 are evenly distributed in the inner cavity of the sample storage cylinder 54. As the sample storage cylinder 54 rotates, the conical feed hopper 55 is driven to rotate together, and the liquid inlet of the conical feed hopper 55 contacts the curved flexible pad 44. The curved flexible pad 44 will wipe the mud and sand sticking to the liquid inlet of the conical feed hopper 55, and as the conical feed hopper 55 continues to rotate, the liquid inlet of the conical feed hopper 55 contacts the elastic cleaning brush 43, and the elastic cleaning brush 43 can be used to clean the mud and sand sticking to the liquid inlet of the conical feed hopper 55.

[0036] When sampling in the sample storage cylinder 54 is completed, the conical feed hopper 55 is driven to rotate by the sample storage cylinder 54, and the liquid inlet of the conical feed hopper 55 is fitted with the curved flexible pad 44, and the driver 52 is paused, so that the liquid inlet of the conical feed hopper 55 squeezes the curved flexible pad 44, and the curved flexible pad 44 uses the action force and reaction force to block the liquid inlet of the conical feed hopper 55, reducing the impact of shaking, and the water and sediment collected in the sample storage cylinder 54 will not flow out.

[0037] The third embodiment, based on the first and second embodiments, see Figures 1 to 9 As shown: The floating mechanism 3 includes a floating airbag 31 and a conical drainage ring 32. The floating airbag 31 is sleeved on the outer circular surface of the supporting base tube 1, and the inner side surface of the floating airbag 31 is fixedly installed on the surface of the supporting base tube 1. The conical drainage ring 32 is fixedly installed at the edge of the top of the supporting base tube 1. The top of the conical drainage ring 32 is fixedly connected to an annular guide extension piece 33. A rectangular through hole 34 is opened in the middle of the surface of the annular guide extension piece 33. An elastic protective net 35 is fixedly installed on the surface of the floating airbag 31. As the telescopic end of the hydraulic cylinder 41 contracts, the cylindrical sleeve 42 is driven to move downward, so that the auxiliary mechanism 47 moves downward as a whole. The divider 473 is inserted into the inside of the rectangular through hole 34 to play a limiting role, and the rectangular washer 474 is between the arc plate 472 and the annular guide extension piece 33. The rectangular washer 474 is squeezed, so that the arc plate 472 is in flexible contact with the annular guide extension piece 33.

[0038] The floating airbag 31 is in contact with the water surface, and the support base tube 1 is floated and supported under the action of buoyancy, so that the detection mechanism 4 will not sink to the bottom of the water, and the elastic protective net 35 is wrapped around the surface of the floating airbag 31 to protect the floating airbag 31, so that the floating airbag 31 is not easily scratched.

[0039] The floating airbag 31, the conical drainage ring 32, the annular guide extension piece 33 and the supporting base tube 1 are concentric circles, and there are four rectangular through holes 34, and the four rectangular through holes 34 are evenly distributed on the surface of the annular guide extension piece 33. When wind and waves hit, the elastic protective net 35 contacts the wind and waves, and the grid-shaped mesh of the elastic protective net 35 is used to divide the wind and waves, so that the impact force of the wind and waves is dispersed and weakened, so that the impact of the wind and waves can be preliminarily processed. Under the drainage of the conical drainage ring 32, the wind and waves are curled and circulated along the arc surface of the inner side of the annular guide extension piece 33, so that the wind and waves can be guided and the frontal impact of the wind and waves is weakened. At the same time, the divider 473 divides the wind and waves guided by the annular guide extension piece 33, and further weakens the impact force of the wind and waves, so that the supporting base tube 1, the detection mechanism 4 and the sampling mechanism 5 are more stable as a whole, and the shaking amplitude is reduced.

[0040] When in use, first place the entire device in the water body to be tested, and the floating airbag 31 contacts the water surface. Under the action of buoyancy, the support base 1 is floated and supported, so that the detection mechanism 4 will not sink to the bottom of the water. The elastic protective net 35 is wrapped around the surface of the floating airbag 31 to protect the floating airbag 31 and prevent it from being scratched. The staff starts the hydraulic cylinder 41 to work. By contracting the telescopic end of the hydraulic cylinder 41, a downward pulling force can be applied to the cylindrical sleeve 42, so that the cylindrical sleeve 42 passes through the center of the supporting base tube 1 and moves downward. The divider 473 is inserted into the interior of the rectangular through-hole 34 to play a limiting role. The rectangular gasket 474 is located between the arc plate 472 and the annular guide extension piece 33. The rectangular gasket 474 is squeezed, so that the arc plate 472 and the annular guide extension piece 33 are in flexible contact, and the equipment as a whole is more stable. The immersion photoelectric sand detector 46 will be driven downward by the cylindrical sleeve 42, and 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 contacts water bodies at different depths, and preliminary detection of the sediment content of water bodies at different depths can be performed; At the same time, as the cylindrical sleeve 42 moves downward, the sampling mechanism 5 is driven to move downward as a whole. When the sample storage cylinder 54 moves to the specified 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, and 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 carrying suspended sediment enters the interior of the sample storage cylinder 54 from the conical feed hopper 55. The sample storage cylinder 54 is always in motion, which promotes the water carrying suspended sediment to evenly enter the sample storage cylinder 54. By evenly distributing the conical feed hoppers 55 along the vertical direction of the sample storage cylinder 54, water and sediment of different depths can be sampled through multiple groups of sample storage cylinders 54, and the circular partitions 56 are used to separate the water and sediment of different depths and store them at different locations inside the sample storage cylinder 54. As the sample storage cylinder 54 rotates, the conical feed hopper 55 is driven to rotate together, and the liquid inlet of the conical feed hopper 55 contacts the curved flexible pad 44, and the curved flexible pad 44 wipes the mud and sand stuck 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 contacts the elastic cleaning brush 43, and the elastic cleaning brush 43 can clean the mud and sand stuck to the liquid inlet of the conical feed hopper 55. When sampling is completed in the sample storage cylinder 54, the conical feed hopper 55 is driven to rotate by the sample storage cylinder 54, and the liquid inlet of the conical feed hopper 55 is fitted with the curved flexible pad 44, and the driver 52 is stopped, so that the liquid inlet of the conical feed hopper 55 squeezes the curved flexible pad 44, and the curved flexible pad 44 blocks the liquid inlet of the conical feed hopper 55 by the action force and reaction force, thereby reducing the influence of shaking, and the water and sediment collected in the sample storage cylinder 54 will not flow out; Moreover, when wind and waves hit, the elastic protective net 35 comes into contact with the wind and waves, and the grid-shaped mesh of the elastic protective net 35 is used to divide the wind and waves, so that the impact force of the wind and waves is dispersed and weakened, thereby preliminarily processing 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 along the arc surface of the inner side of the annular guide extension piece 33, thereby guiding the wind and waves and weakening the frontal impact of the wind and waves. At the same time, the divider 473 divides the wind and waves guided by the annular guide extension piece 33, further weakening the impact force of the wind and waves, making the support base tube 1, the detection mechanism 4 and the sampling mechanism 5 more stable as a whole and reducing the shaking amplitude. When the sampling is completed, the hydraulic cylinder 41 can be opened again to work, and the telescopic end of the hydraulic cylinder 41 is extended to push the cylindrical sleeve 42 upward to move it, and the sampling mechanism 5 is moved upward as a whole, so that the sealing plug 57 can be removed and the sample in the sample storage cylinder 54 can be taken out for further analysis and testing.
