[0002] Sediment particle size and its spatial distribution are crucial for river research (such as flow resistance, riverbed evolution, aquatic habitat research, etc.) and river management (such as river dredging, river restoration, etc.). However, the measurement of sediment particle size in river environments, especially for mountain rivers with wide particle gradations, has always been very challenging.

[0003] In order to facilitate better monitoring of sediment, the sediment particle size monitoring device needs to be placed in the water.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0036] See also Figure 1-Figure 7 As shown, the present invention is a sediment particle size monitoring device for river flow monitoring, comprising a conical tube 1, at least three of the conical tubes 1 are installed in sequence from left to right, and the tube mouths of the three conical tubes 1 are opposite to the water flow direction of the river, the outer tube wall of the conical tubes 1 that are installed in sequence from left to right is designed to be non-contact with the other outer tube wall, the mesh formed by the tube wall of the conical tube 1 on the left is located inside the conical tube 1 on the right, and the diameters of the mesh holes opened on the tube walls of the three conical tubes 1 decrease in sequence from left to right, a particle size monitoring component 6 is detachably installed at the tube mouth of the conical tube 1 on the far left through a supporting mechanism 5, and at least three of the conical tubes 1 are installed in the river to be monitored by supporting a settling component 8 and settling;

[0037] Specifically, the present invention comprises at least three conical cylinders 1 connected in sequence, and a particle size monitoring component 6 is detachably installed at the tube mouth of the leftmost conical cylinder 1 through a supporting mechanism 5. The supporting and settling component 8 is first installed in the river channel to be monitored, and then the three conical cylinders 1 are installed in the river channel through partial structural settling of the supporting and settling component 8, so that the three conical cylinders 1 are immersed in the river, and the tube mouth of the conical cylinder 1 is opposite to the flow direction of the river, and then the particle size monitoring component 6 at the tube mouth of the conical cylinder 1 can monitor the particle size of the silt particles flowing in the river, and when the flowing silt particles enter the conical cylinder 1, the mesh on the first conical cylinder 1 on the left will intercept the large particles of silt, while the medium particles of silt will pass through the mesh. The hole enters into the second conical tube 1, and then the second conical tube 1 will intercept the medium-sized silt particles, while the fine-grained silt particles will pass through the second layer of mesh holes and enter into the rightmost conical tube 1, thereby realizing the classification and collection of the mixed silt particles in the river, and then facilitating the operator to sample and monitor the graded and collected silt particles as needed. Therefore, the monitoring device of the present invention can not only monitor the particle size of the mixed silt particles in the river, but also classify and sample the monitored silt particles, so that the operator can accurately analyze the types of silt particles of different sizes according to the data of the particle size of the monitored silt particles, thereby improving the scope of use of the monitoring device of the present invention.

[0038] In the scheme designed by the present invention, the tails of the three conical cylinders 1 can be detachably installed with a collection box 3, and the outer ring surface of the collection box 3 is slidably inserted into a sliding slot provided on the inner ring surface of the tail of the conical cylinder 1 through a plurality of plug blocks 31. A support rotation assembly 4 is arranged in the conical cylinder 1, and the support rotation assembly 4 includes a shaft 41, an impeller 42, blades 43, a support ring 44, an annular disk 45, an electric push rod 46, a connecting rod 47 and a rotating sleeve 48. The shaft 41 is horizontally inserted into the three conical cylinders 1, and the shaft body of the shaft 41 is connected to the three collection boxes 3. The tail of the shaft 41 is fixed with an impeller 4 2, and a plurality of blades 43 are installed on the impeller 42, the diameter of the plurality of blades 43 is larger than the diameter of the largest conical cylinder 1, the outer ring surface of the conical cylinder 1 at both ends is fixed with a support ring 44, and the support ring 44 is rotatably mounted on an annular disk 45, the annular disk 45 is connected to the support and settling assembly 8, and a plurality of electric push rods 46 are installed in a circumferential array on the outer ring surface of the right side wall of the annular disk 45 located on the far right, and the piston rod end surfaces of the plurality of electric push rods 46 are vertically connected with connecting rods 47, and the ends of the plurality of connecting rods 47 are rotatably connected to the shaft 41 through the cooperation of a rotating sleeve 48 and a bearing;

[0039] Specifically, after the three conical tubes 1 are installed in the river channel by supporting the sedimentation assembly 8, if only the particle size of the silt particles in the river needs to be monitored, the piston rods of the multiple electric push rods 46 on the right annular disk 45 are controlled to extend, so that they push the shaft 41 to slide rightward in the conical tube 1 through the connecting rod 47 and the rotating sleeve 48. At this time, the sliding shaft 41 will drive the three collecting boxes 3 to be pulled out and disengaged from the tails of the three conical tubes 1, so that the three conical tubes 1 are in a completely through state, thereby facilitating the flowing river water to flow stably and safely in the three conical tubes 1, so that the particle size monitoring assembly 6 can accurately monitor the particle size of the silt particles in the river water, and when the river water flows, it will rotate through the multiple blades 43 on the impeller 42, and then the shaft 41 will drive the three collecting boxes 3 to rotate, so that the silt impacted in the collecting boxes 3 can be centrifugally thrown out;

[0040] When it is necessary to collect samples of the sediment particles being monitored, the piston rods of the multiple electric push rods 46 are retracted, so that the piston rods 46 drive the shaft 41 to slide to the left in the conical tube 1 through the connecting rod 47 and the rotating sleeve 48. At this time, the plug block 31 on the outer ring surface of the collection box 3 will slide into the sliding slot, so that the collection box 3 will be sealed and covered to the tail of the conical tube 1. Then, the mixed sediment in the river water flowing into the conical tube 1 will be intercepted and separated by multiple layers of mesh holes of different sizes, and the separated sediment particles will gather in the collection box 3. When the river water flows through the blade 43, since the diameter of the blade 43 is larger than the diameter of the conical tube 1, the river water will push the blade 43 to rotate, and since the collection box 3 is connected to the conical tube 1, the river water will push the blade 43 to rotate. The cone tube 1 is on the cone tube 1, and the cone tube 1 is rotatably supported on the annular disk 45 by the support ring 44. Therefore, the rotation of the shaft 41 will drive the three cone tubes 1 to rotate in the flow channel of the river, so that the sediment particles flowing into the cone tube 1 can be centrifugally flushed to quickly grade the sediment particles for sampling and collection, so that the collected sediment particles will not gather in large quantities inside the lower cylinder wall of the cone tube 1, thereby affecting its collection effect. When the collection is completed, the three cone tubes 1 are taken out from the river channel, and then the piston rod of the electric push rod 46 can be extended to drive the three collection boxes 3 to detach from the cone tube 1, so that the graded sediment particles in the collection box 3 can be quickly taken out and tested.

[0041] In the scheme designed by the present invention, a fitting ring 49 is provided at the contact position between the tail of the conical cylinder 1 and the box opening of the slidably inserted collection box 3, and a plurality of scrapers 491 are connected to the circumference of the side of the fitting ring 49, and the plurality of scrapers 491 fit to the mesh holes opened on the cylinder wall of the conical cylinder 1, and a plurality of supporting connecting rods 492 are installed in a circumferential array on the inner ring surface of the fitting ring 49, and the plurality of supporting connecting rods 492 face the cylinder center of the conical cylinder 1, and the ends of the plurality of supporting connecting rods 492 are connected to the same connecting ring 493, and a plurality of engaging strips 411 are installed on the outer ring surface of the shaft rod 41, and the engaging strips 411 are slidably inserted into the key groove opened on the inner ring surface of the connecting ring 493;

[0042] Specifically, when the shaft 41 slides to the right and opens the three collecting boxes 3 from the tail of the conical tube 1, the engaging strip 411 on the shaft 41 will slide and insert into the key groove provided on the inner ring surface of the connecting ring 493, and then when the blade 43 is pushed by the water flow, the rotating shaft 41 will drive the rotating fitting ring 49 to rotate through the connecting ring 493 and the supporting connecting rod 492, and then the fitting ring 49 will drive the multiple scrapers 491 to rotate around the inner tube wall of the conical tube 1, so that the rotating scrapers 491 can scrape and clean the impurities gathered at the mesh holes provided on the inner tube wall of the conical tube 1, thereby preventing The mesh holes are clogged with granular impurities, which affects the subsequent sealing of the conical tube 1 for the graded sampling and collection of sediment particles; when the shaft 41 drives the collecting box 3 to be inserted into the tail of the conical tube 1, the collecting box 3 will squeeze and fix the fitting ring 49, and the engaging strip 411 on the shaft 41 will be disengaged from the keyway of the connecting ring 493, so that the shaft 41 is disengaged from the connection with the connecting ring 493, and the multiple scrapers 491 will be in a stationary state, and then the rotation of the shaft 41 will drive the multiple conical tubes 1 to rotate through the connection between the collecting box 3 and the conical tube 1 to perform centrifugal graded sampling and collection on the incoming sediment particles.

[0043] In the scheme designed by the present invention, the support mechanism 5 includes a support long block 51, a push rod 52, a docking column 53, a sleeve tube 54, a connecting strip 55, a support long rod 56 and a mounting sleeve 57. The outer ring surface of the tapered tube 1 located on the left side is formed with a raised ring 2, and an annular groove 21 is provided in the raised ring 2. A plurality of support long blocks 51 are rotatably installed in the annular groove 21, and a plurality of push rods 52 are installed at the outer ends of the plurality of support long blocks 51 toward the center of the tapered tube 1. The end surfaces of the plurality of push rods 52 are all installed with docking columns 53, and the outer ring surface of the docking column 53 is provided with a groove along its length direction. There are multiple limiting guide grooves 531, and the outer ring surface of each of the docking columns 53 is sleeved with a sleeve tube 54, and the inner ring surface of the sleeve tube 54 is slidably connected to the limiting guide groove 531 through multiple connecting strips 55, and the bottom of the connecting strip 55 is connected to the bottom of the limiting guide groove 531 through a spring member, and a supporting long rod 56 is slidably inserted in the sleeve tube 54, and the supporting long rod 56 is also provided with a limiting slot 561 that cooperates with the connecting strip 55, and the ends of the multiple supporting long rods 56 that are close to each other are fixed to the same mounting sleeve 57, and the particle size monitoring component 6 is installed in the mounting sleeve 57;

[0044] Specifically, when it is necessary to install the particle size monitoring component 6 at the mouth of the conical cylinder 1, the multiple support blocks are first inserted into the annular groove 21 in sequence, and then the multiple support long rods 56 on the installation sleeve 57 are aligned with the multiple sleeve tubes 54, and the sleeve tubes 54 are moved to slide toward the push rod 52 to leak the docking column 53. At this time, the sliding of the connecting strip 55 will cause the spring member in the limiting guide groove 531 to be compressed. When the bottom end of the support long rod 56 contacts the docking column 53, the sleeve tube 54 is released, and the elastic restoring force of the spring member will push the sleeve tube 54 to the connecting strip 55. The supporting long rod 56 slides in the direction, and at this time the connecting strip 55 will slide upward into the limiting slot 561, so that the supporting long rod 56 can be stably and safely inserted into the sleeve tube 54 for fixing, and then the particle size monitoring component 6 is installed in the installation sleeve 57 to achieve the installation and fixation of the particle size monitoring component 6; and when the conical tube 1 rotates, at this time, since the multiple supporting long blocks 51 are rotatably set in the annular groove 21, the installed particle size monitoring component 6 will not rotate synchronously with the conical tube 1, so that the particle size monitoring component 6 can always monitor the particle size of sediment particles in one direction.

[0045] In the scheme designed by the present invention, a push-and-engage component 7 is arranged in the supporting long block 51, and the pushing-and-engage component 7 includes an arc-shaped engaging block 71, an extrusion protrusion 72, a wedge-shaped pushing block 73, a reset spring 74, an arc-shaped sealing plate 75 and an elastic buckle strip 76. The groove walls on both sides of the annular groove 21 are provided with an annular engaging groove 22. A pushing cavity 511 is arranged inside the supporting long block 51, and the two side walls of the pushing cavity 511 are provided with a push-up slide groove aligned with the annular engaging groove 22. An arc-shaped engaging block 71 is slidably arranged in the push-up slide groove, and the inner side surface of the arc-shaped engaging block 71 is connected to the cavity wall of the pushing cavity 511 through the cooperation of the extrusion protrusion 72 and the spring member. A wedge-shaped push block 73 is slidably arranged in 511, and the inclined surfaces on both sides of the wedge-shaped push block 73 are in contact with the arc surface of the extrusion protrusion 72. The push rod 52 is slidably inserted into the push cavity 511 and connected with the end surface of the wedge-shaped push block 73. A return spring 74 is sleeved on the inserted push rod 52, and the two ends of the return spring 74 are respectively connected with the wedge-shaped push block 73 and the cavity wall of the push cavity 511. A plurality of arc-shaped sealing plates 75 are rollingly arranged in the annular groove 21, and the two ends of each arc-shaped sealing plate 75 are respectively in contact with two adjacent supporting long blocks 51. The arc-shaped sealing plate 75 is rollingly installed in the annular groove 21 through the mutual cooperation of the elastic buckle strip 76 and the annular clamping groove 22;

[0046] When the locking cam 72 is in the unlocking state, the locking cam 72 is in the unlocking state, and the locking cam 72 is in the unlocking state, so that the locking cam 72 is locked and the locking cam 72 is locked. The supporting long block 51 at the top falls out of the annular groove 21, and since the arc-shaped engaging block 71 pushed out is rolled and engaged into the annular engaging groove 22, it only limits the supporting long block 51 from falling, and will not fix the supporting long block 51 into the annular groove 21, thereby not affecting the safe and stable support of the particle size monitoring component 6; and when the arc-shaped engaging block 71 is extended, the end of the supporting long rod 56 is attached to the docking column 53, and then the sleeve 54 is loosened, so that it can synchronously sleeve and fix the docking column 53 and the supporting long rod 56, thereby making the supporting long rod 56 The support rod 56 can not only fix and support the installation sleeve 57, but also limit and fix the sliding wedge-shaped push block 73 through the push rod 52, so as to prevent the extended arc-shaped engaging block 71 from escaping from the annular engaging groove 22 and affecting the limiting of the support long block 51; and when the particle size monitoring component 6 needs to be disassembled, the sleeve tube 54 is continued to be moved to slide in the direction of the push rod 52, and then the support long rod 56 is separated from the docking column 53, and then the wedge-shaped push block 73 will slide in the opposite direction under the elastic restoring force of the reset spring 74 to disengage from the extrusion protrusion 72. The spring element on the extrusion protrusion 72 will pull the arc-shaped engaging block 71 back into the push slide groove, so that it will be disengaged from the annular engaging groove 22, thereby facilitating the removal of the parts of the support mechanism 5 from the conical tube 1; and the design of the arc-shaped sealing plate 75 and the elastic buckle strip 76 can seal the annular groove 21 without affecting the relative static state of the supporting long block 51, thereby preventing the mud and sand particles in the conical tube 1 from entering the annular groove 21, thereby causing the supporting long block 51 to be unable to remain relatively static in the annular groove 21 to stably support the particle size monitoring component 6.

[0047] In the scheme designed by the present invention, the support and settlement assembly 8 includes a support anchor rod 81, a support tube 82, a connecting side rod 83, a counterweight block 84, a docking block 85 and a threaded long rod 86. A plurality of the support anchor rods 81 are fixed to the river channel, and each support anchor rod 81 is sleeved with a support tube 82. The outer ring surface of the annular disk 45 is symmetrically fixed with a connecting side rod 83, and the connecting side rod 83 is sleeved on the support anchor rod 81. The upper and lower end surfaces of the sleeved connecting side rod 83 are in contact with the counterweight block 84, and the counterweight block 84 is also sleeved on the support anchor rod 81. The outer side surfaces of the counterweight block 84 and the connecting side rod 83 are fixed with a docking block 85, and a threaded hole is opened on the docking block 85. The threaded holes of the plurality of the docking blocks 85 are connected with the same vertical threaded long rod 86, and the top end of the threaded long rod 86 is higher than the support anchor rod 81.

[0048] Specifically, a plurality of support anchor rods 81 are fixed to the river channel of the river to be monitored, and then the support tubes 82 are sequentially sleeved on the support anchor rods 81.
