Detailed Implementation

[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] The purpose of this invention is to provide a suspended sediment collector for controlling the depth of sediment cleaning while cleaning the sediment.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figure 1 , Figure 2 This embodiment provides a suspended sediment collector, including a cover 1, a sediment suction assembly, a buoyancy assembly, and a signal assembly.

[0030] The enclosure 1 is used to invert and rest on the bottom sediment, and its sidewalls can filter the sediment. The sediment suction assembly includes a pump body 2, a suction pipe, and a discharge pipe 3. The suction pipe is located inside the enclosure 1, with one end connected to the inlet of the pump body 2 and the other end used to suction the sediment. The discharge pipe 3 is located outside the enclosure 1, with one end connected to the outlet of the pump body 2 and the other end used to discharge the sediment. The buoyancy assembly includes an elastic airbag 4 and an inflation pipe 56. The elastic airbag 4 is connected to the enclosure 1, and the first end of the inflation pipe 5 is connected to the elastic airbag 4. The second end of the inflation pipe 5 is provided with an inflation nozzle 12 for connecting to an inflation device. The signal assembly includes a rope 7, a first float 8, and a second float 9. The rope 7 has a connection position, a first fixed position, and a second fixed position. The connection position is fixed to the enclosure 1, the first float 8 is fixed to the first fixed position, and the second float 9 is fixed to the second fixed position. When the cover 1 touches the surface of the bottom mud, the rope 7 between the connecting position and the first fixed position is tightened. When the cover 1 reaches the dredging depth, the rope 7 between the first fixed position and the second fixed position is tightened. It can be understood that in this embodiment, the dredging depth is the length of the rope 7 between the first fixed position and the second fixed position.

[0031] The working principle of the suspended sediment collector in this embodiment is as follows:

[0032] First, the elastic airbag 4 is inflated using an inflation device, and the internal air pressure is monitored using a pressure gauge 6. After inflation, the buoyancy component floats on the water surface, and the cover 1 is at least partially submerged, but not touching the bottom sediment. Then, the air inside the elastic airbag 4 is gradually expelled. When the volume of the elastic airbag 4 decreases to a certain extent, the buoyancy component sinks into the water, and the first float 8 and the second float 9 float on the water surface. At this point, the deflation process of the elastic airbag 4 is stopped. The first float 8 stops sinking after descending a distance D from the water surface, indicating that the cover 1 has touched the bottom sediment surface. At this point, the pump 2 is activated, and the bottom sediment is discharged sequentially through the sludge suction pipe, pump 2, and discharge pipe 3 to the bottom sediment storage location on the shore or on the engineering vessel. When the second float 9 begins to sink from the water surface, pump 2 is turned off, and the elastic airbag 4 is inflated using the inflation device, causing the entire suspended bottom sediment collector to float back to the water surface. The suspended bottom sediment collector is then towed to the next cleaning location, and the above operation is repeated. The distance D can be set according to the actual situation, such as 10cm, as long as it allows the operator to easily observe the changes in the draft of the first float 8. However, the distance D should not be too large, otherwise it will be difficult to observe when the first float 8 stops sinking after it is fully submerged.

[0033] As a possible example, in this embodiment, the buoyancy component also includes a pressure gauge 6, which is mounted on the inflation tube 5. It should be noted that the volume of the elastic airbag 4 during elastic expansion is positively correlated with its internal air pressure. By adjusting its internal air pressure, the volume of the elastic airbag 4 can be controlled, thereby controlling the overall buoyancy of the suspended sediment collector. By repeatedly performing the sinking operation of the buoyancy component and observing the changes in the pressure gauge 6, the approximate range of the internal air pressure of the elastic airbag 4 when the buoyancy component just begins to sink can be obtained. To avoid the bottom of the cover 1 sinking deeply into the sediment when it touches the sediment due to excessive reduction in the buoyancy of the elastic airbag 4, the air pressure inside the elastic airbag 4 should be as close as possible to the upper extreme of this approximate range when the deflation of the elastic airbag 4 is complete. In this embodiment, the air pressure when the deflation of the elastic airbag 4 is complete is referred to as the sinking air pressure.

[0034] Furthermore, the length of the rope 7 between the connecting position and the first fixed position can be adjusted by those skilled in the art based on the actual water depth. When the rope 7 is vertically taut, the vertical distance between the lower end of the cover 1 and the first float 8, plus the distance D, equals the water depth of the construction area (which can be measured beforehand) plus the height of the center of the first float 8 above the water surface when it is suspended. To facilitate adjustment of the position of the first float 8, the rope 7 in this embodiment has dimensional markings. Since the vertical distance from the bottom of the cover 1 to the connecting position of the rope 7, and the height of the center of the first float 8 above the water surface when it is suspended, are fixed, the length of the rope 7 between the connecting position and the first fixed position can be calculated simply by knowing the water depth of the construction area.

[0035] As a possible example, in this embodiment, the buoyancy assembly also includes a one-way air inlet valve 10 and a pressure relief valve 11. The inflation nozzle 12, the one-way air inlet valve 10, and the pressure relief valve 11 are sequentially arranged on the inflation pipe 5. The one-way air inlet valve 10 only allows airflow in one direction into the elastic airbag 4, and the pressure relief valve 11, once opened, allows the gas inside the elastic airbag 4 to be discharged. If a scheme without the one-way air inlet valve 10 and the pressure relief valve 11 is adopted, the gas enters and exits the elastic airbag 4 from the inflation nozzle 12. After inflation is completed, the inflation pipe 5 at the inflation nozzle 12 needs to be closed by tying a knot or using a clamp.

[0036] As a possible example, in this embodiment, the buoyancy component further includes an air reservoir 13, which is connected to the cover 1. The volume of the air reservoir 13 remains constant, therefore its buoyancy is also constant. In this embodiment, the purpose of providing the air reservoir 13 is to reduce the volume of the elastic airbag 4.

[0037] As a possible example, in this embodiment, both the elastic airbag 4 and the air reservoir 13 are fixed to the top of the cover 1. That is, when the buoyancy assembly floats on the water surface, the cover 1 is completely submerged in water. In this way, the buoyancy of the cover 1 itself is fully utilized, and the volume of the air reservoir 13 and the elastic airbag 4 can be reduced accordingly.

[0038] As a possible example, in this embodiment, the elastic airbag 4 is annular. Multiple air reservoirs 13 are included, forming a square structure. The elastic airbag 4 is located inside the square structure. Depending on the actual needs, those skilled in the art can also choose other shapes of elastic airbags 4, and arrange the air reservoirs 13 in other forms.

[0039] As a possible example, in this embodiment, the suspended sediment collector further includes a blade assembly comprising a first blade 14 and a second blade. Both the first blade 14 and the second blade are fixed to the lower inner side of the cover 1 and are positioned opposite each other. When the rope 7 between the connecting position and the first fixed position is tightened, the bottom of the cover 1 touches the surface of the sediment, and the first blade 14 and the second blade are inserted into the sediment. In this embodiment, the first blade 14 and the second blade form a figure-eight structure. Since both the first blade 14 and the second blade are located inside the cover 1, when the cover 1 moves horizontally, the sediment scooped up by the blades will not spread to the outside of the cover 1.

[0040] As a possible example, in this embodiment, the blade assembly further includes a plurality of pads fixed to the lower end of the cover 1. The pads include a first pad for fixing a first blade 14 and a second pad 15 for fixing a second blade. The first pad has an inclined surface for supporting the first blade 14, and the second pad 15 has an inclined surface for supporting the second blade. The inclined surfaces support the blade face to position the first blade 14.

[0041] As a possible example, in this embodiment, the suspended sediment collector also includes a traction rope 16, which is connected to the cover 1, specifically to a pull ring 17 on the outside of the cover 1. By pulling the traction rope 16, the suspended sediment collector can be moved in the water.

[0042] As a possible example, in this embodiment, the cover 1 has a frustum-shaped structure, specifically a regular square frustum-shaped structure, and the cross-sectional area of ​​the cover 1 gradually increases from top to bottom. Depending on the actual needs, those skilled in the art may also choose other forms of cover 1, such as a frustum of a cone.

[0043] As a possible example, in this embodiment, the elastic airbag 4 is made of rubber, the air reservoir 13 is a cylindrical body made of PVC, and the first float 8 and the second float 9 are hollow spheres made of PVC. Depending on the actual needs, those skilled in the art may also choose other materials.

[0044] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
