Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy, and in particular to a buoy-type river ecological bank protection structure. Background Art

[0002] As a crucial component of water conservancy projects, riverbank protection structures play an irreplaceable role in flood control, embankment protection, and maintaining the ecological balance of rivers. Traditional revetment designs often utilize rigid structures such as concrete, gabions, or steel sheet piles. While these structures are somewhat effective in resisting water flow and maintaining riverbank stability, they often neglect integration with the natural environment and fail to meet the demands of modern ecological conservation. In recent years, with the advancement of ecological civilization, floating revetments have gradually gained attention as an innovative design that combines flood control with ecological functions. By adapting to changes in water flow through flexible structures, floating revetments attempt to protect the riverbank while promoting the habitat of aquatic life and the sustainable development of river ecosystems.

[0003] However, existing floating revetment technology still has significant shortcomings in practical application, particularly in complex hydrological conditions, where its impact resistance is limited. Existing floating revetment structures typically have a simple design and lack an effective resistance regulation mechanism, making them unable to adapt to dynamic changes in river water levels and varying current intensities. As a result, when the water flow is turbulent or the water level fluctuates dramatically, the revetment structure is unable to effectively offset the impact of the current, making it prone to displacement, uncontrolled rotation, or structural damage, which in turn affects the stability and long-term effectiveness of the revetment. Summary of the Invention

[0021] The above and other technical features and advantages of the present invention are described in more detail below with reference to the accompanying drawings.

[0022] This embodiment provides a technical solution: a buoy-type river ecological bank protection structure, such as Figures 1 to 6 As shown, it includes a guard plate 1, multiple columnar pontoons 2, multiple flow-blocking mechanisms 3 and multiple resistance mechanisms 4; the setting of the guard plate 1 can protect the embankment, and the side of the guard plate 1 close to the upstream of the river channel is provided with an inclined guide surface 11. The setting of the inclined guide surface 11 can make the water in the upstream of the river channel flow downward more smoothly to the side of the columnar pontoon 2, reducing the impact on the guard plate 1. In addition, in order to fix the guard plate 1, a plug rod 15 can be provided at the bottom of the guard plate 1, and the plug rod 15 can be inserted into the bottom of the river channel, and a transverse fixing rod 12 is also provided on the side of the guard plate 1 close to the embankment, and the transverse fixing rod 12 can be fixed to the embankment to ensure the reliability of the guard plate 1.

[0023] A plurality of vertical arc grooves 13 are provided on one side of the guard plate 1, and the surface is located on the side facing the center of the river channel. A plurality of columnar floats 2 are respectively rotatably arranged in the plurality of vertical arc grooves 13, and the columnar floats 2 can be vertically displaced in the vertical arc grooves 13. A gap is set between the outer circumference of the columnar float 2 and the inner circumference of the vertical arc groove 13, which can reduce the water flow entering between the guard plate 1 and the columnar float 2; specifically, the columnar float 2 is fixed with a rotating rod 21 arranged along its central axis, and the lower end of the guard plate 1 is fixed with a mounting tube 14, and the lower end of the rotating rod 21 is inserted into the mounting tube 14. When this structure is in operation, the rotating rod 21 and the mounting tube 14 have sufficient axial overlapping dimensions to ensure that the lower end of the rotating rod 21 will never separate from the mounting tube 14.

[0024] The upper end of the rotating rod 21 is connected to the resistance mechanism 4, which is arranged on the top of the cylindrical pontoon 2 and is fixedly connected to the guard plate 1. The resistance mechanism 4 is used to increase the torque required for the rotation of the cylindrical pontoon 2 to offset the impact force of the river water flow.

[0025] The resistance mechanism 4 includes a lower ring block 43 mounted on the upper end of the rotating rod 21 and a mounting cylinder 49 fixed to the guard plate 1 through a bracket. A first annular grinding wheel 41 is mounted on the lower ring block 43, a mounting block 46 is mounted in the mounting cylinder 49, and a second annular grinding wheel 42 is mounted on the lower end of the mounting block 46. The first annular grinding wheel 41 and the second annular grinding wheel 42 are made of the same material as conventional grinding wheels, for example, made of abrasives (such as aluminum oxide, silicon carbide) and a binder, with hard abrasive grains embedded on the surface, and their surfaces will have Due to the larger friction, the first annular grinding wheel 41 and the second annular grinding wheel 42 are in contact with each other, and the abrasive particles of the two will collide and squeeze each other, causing the abrasive particles to fall off or break. The abrasive particles on the surface of the first annular grinding wheel 41 and the second annular grinding wheel 42 will be worn, but a smooth surface will not be formed because the falling of the abrasive particles will expose new rough particles or irregular surfaces. Therefore, when the first annular grinding wheel 41 and the second annular grinding wheel 42 are in contact with each other, the torque required for the rotation of the cylindrical buoy 2 can be increased to offset the impact force of the river water. At the same time, when the water level in the river is higher, the upward buoyancy of the cylindrical buoy 2 will also be greater, thereby increasing the contact force between the second annular grinding wheel 42 and the first annular grinding wheel 41, and also increasing the torque required for the rotation of the cylindrical buoy 2 and offsetting the impact force of the river water. Therefore, the water level in the river is proportional to the ability of the cylindrical buoy 2 to offset the impact force of the river water.

[0026] Furthermore, the mounting block 46 is vertically slidably arranged in the mounting cylinder 49, the top of the mounting cylinder 49 is threadedly connected with a plum blossom bolt 410, and the bottom of the plum blossom bolt 410 is rotatably installed with a push plate 48, and a compression spring 47 is arranged between the push plate 48 and the mounting block 46. The force of the compression spring 47 can enable the second annular grinding wheel 42 to be vertically displaced to ensure that the first annular grinding wheel 41 and the second annular grinding wheel 42 can always remain in contact with each other, and by twisting the plum blossom bolt 410, the vertical position of the push plate 48 can be adjusted, and the downward force exerted by the compression spring 47 on the mounting block 46 can be adjusted, thereby adjusting the friction between the first annular grinding wheel 41 and the second annular grinding wheel 42.

[0027] Furthermore, in order to enable the first annular grinding wheel 41 and the second annular grinding wheel 42 to be replaced, a plurality of lower clamping grooves 44 are provided on the circumference of the upper end of the lower ring block 43, and a plurality of first latch portions are formed. A plurality of lower clamping blocks 45 are fixed on the circumference of the lower end of the first annular grinding wheel 41, and the plurality of lower clamping blocks 45 are respectively engaged with the plurality of lower clamping grooves 44 to fix the first annular grinding wheel 41; an upper ring block 411 is fixed on the lower end of the mounting block 46, and a plurality of upper clamping grooves 412 are provided on the circumference of the lower end of the upper ring block 411, and a plurality of second latch portions are formed. A plurality of upper clamping blocks 413 are fixed on the circumference of the upper end of the second annular grinding wheel 42, and the plurality of upper clamping blocks 413 are respectively engaged with the plurality of upper clamping grooves 412 to fix the second annular grinding wheel 42.

[0028] During operation, the first annular grinding wheel 41 rotates synchronously with the cylindrical pontoon 2, while the second annular grinding wheel 42 does not rotate. Therefore, when the cylindrical pontoon 2 rotates, the first annular grinding wheel 41 and the second annular grinding wheel 42 rotate relative to each other, causing friction and increasing the torque required to rotate the cylindrical pontoon 2. When the first annular grinding wheel 41 and the second annular grinding wheel 42 are worn, they can be replaced with new ones. The upper end of the rotating rod 21 is rotatably mounted within the upper ring block 411, and a circular hole is provided at the bottom of the mounting block 46 to accommodate the upper end of the rotating rod 21.

[0029] A plurality of flow-blocking mechanisms 3 are respectively arranged on a plurality of cylindrical pontoons 2. The flow-blocking mechanisms 3 include a plurality of circumferentially distributed baffles 34 slidably arranged on the cylindrical pontoons 2 and a C-shaped guide plate 36 fixed to the guard plate 1. The C-shaped guide plate 36 is located outside the vertical arc groove 13. The C-shaped guide plate 36 has an arc portion, and the center of the arc portion is located at the same point as the rotating circle of the cylindrical pontoon 2. Both sides of the arc portion have inclined portions that smoothly connect with the vertical arc groove 13 to ensure that the C-shaped guide plate 36 is in contact with the vertical arc groove. The inner wall of 13 is a sealed curved structure. The outer circumferential surface of the cylindrical float 2 is provided with a plurality of annularly distributed elongated grooves 31. A plurality of baffles 34 are slidably installed in the plurality of elongated grooves 31, and a spring 33 is installed in the elongated groove 31 to allow the baffles 34 to move outward. A roller 35 is rotatably installed on the outer side of the baffle 34. A transverse slide bar 32 is fixed in the elongated groove 31. The transverse slide bar 32 is slidably connected to the baffle 34. The number of springs 33 and transverse slide bars 32 is set according to needs.

[0030] The cylindrical pontoon 2 rotates as it is pushed by the water flow in the river. When the roller 35 contacts the inner wall of the C-shaped guide plate 36, the baffle 34 extends out of the outside of the cylindrical pontoon 2 under the action of the spring 33, so that it can contact more water flow and increase the impact force to offset the river water flow. When the roller 35 contacts the inner wall of the vertical arc groove 13, it will be retracted into the interior of the cylindrical pontoon 2. It should be noted that the C-shaped guide plate 36 has a certain vertical dimension to ensure that the roller 35 is always in contact with the C-shaped guide plate 36 during the vertical displacement of the cylindrical pontoon 2.

[0031] In order to ensure that the silt on the inner walls of the vertical arc groove 13 and the C-shaped guide plate 36 accumulates over time and does not interfere with the normal operation of the roller 35, a scraper 38 is rotatably installed on one side of the baffle 34 through a mounting seat, and a torsion spring 39 is installed on the mounting seat to drive the scraper 38 to flip outward. The scraper 38 is located in the forward direction of the rotation of the baffle 34. Therefore, the force of the torsion spring 39 will make the outer end of the scraper 38 always contact the inner walls of the vertical arc groove 13 and the C-shaped guide plate 36, so that the silt on the side walls of the vertical arc groove 13 and the C-shaped guide plate 36 can be removed by the scraper 38; a receiving groove 37 for receiving the scraper 38 is provided on the outer side of the columnar float 2. When the baffle 34 rotates into the vertical arc groove 13, the scraper 38 can be received in the receiving groove 37.

[0032] An elongated through hole is provided at the upper end of the rotating rod 21, and the lower end of the mounting block 46 is fixed to and extends to a vertical rod 51 in the elongated through hole. At least one push ring 52 is fixed on the vertical rod 51, and a sliding ring 53 slidably installed in the elongated through hole is provided on the lower side of the push ring 52, and the vertical rod 51 passes through the sliding ring 53. A plurality of pull ropes 54 are fixed to the outside of the sliding ring 53, and the outer ends of the plurality of pull ropes 54 are respectively fixedly connected to a plurality of blocking plates 34.

[0033] When the first annular grinding wheel 41 and the second annular grinding wheel 42 are completely worn, due to the upward buoyancy force of the river water flow on the columnar float 2 and the downward force of the compression spring 47 on the mounting block 46, the multiple first latch parts are respectively inserted into the multiple upper slots 412, and the multiple second latch parts are respectively inserted into the multiple lower slots 44, preventing the columnar float 2 from rotating, and realizing that the push ring 52 pushes the sliding ring 53 to move downward, and the baffle 34 is pulled back into the interior of the columnar float 2 by the pull rope 54, thereby reducing the force of the river water flow on the columnar float 2.

[0034] In order to ensure that the lower clamping block 45 and the upper clamping block 413 can smoothly disengage from the lower clamping groove 44 and the upper clamping groove 412 when the first annular grinding wheel 41 and the second annular grinding wheel 42 are completely worn, the bottom of the lower clamping groove 44 and the top of the upper clamping groove 412 are both inclined.

[0035] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, all of which fall within the scope of protection of the present invention.
