Description

Technical Field

[0001] The present invention relates to the technical field of bank protection engineering, in particular to a bank protection engineering hydraulic structure and a bank protection method thereof. Background Art

[0002] The hydraulic structures of bank protection projects are diverse, mainly including slope-type, dam-type, and wall-type bank protection. Building materials or components are directly laid on the waterside slope of the embankment or beach to form a continuous covering layer. They are arranged in the direction of water flow, with little impact on the water flow and no impact on shipping.

[0003] In the patent document with publication number CN117868051A, a hydraulic structure for a bank protection project is proposed. By longitudinally arranging supporting square tubes 1 and 2 in the base layer on both sides of the river channel, and then horizontally arranging connecting tubes 1 and 2 below both sides of the river channel, connecting tubes 1 and 2 are connected to supporting square tubes 1 and 2 respectively through corresponding clamping blocks. It can be used to reinforce the entire river bank, protect the inner side of the river bank, reduce soil erosion, and increase the stability of the river bank.

[0004] However, the bank protection project reduces the impact force by using backflow water to offset the water in the bank. However, the impact force of the water flow on the bank is different in each time period. When the impact force is weak, the backflow can easily lead to sediment deposition on the bank. Summary of the Invention

[0011] Optionally, a guide cylinder is fixedly installed on the outer wall of the fixed bin, and the outer wall of the top rod is slidably connected to the guide cylinder. A plurality of the bank protection steel plates are provided and are laid end to end on the vertical surface of the concrete bank protection. Two symmetrically distributed top rods are provided on the side of each of the bank protection steel plates.

[0012] Optionally, a stepped groove is provided on the stop block, and the end of the push rod is rotatably connected to a roller, and the roller rolls along the stepped groove.

[0013] Optionally, the buffer member includes a spring telescopic rod, which is fixedly mounted on the end of the push rod, and a positioning plate is fixedly mounted on the end of the spring telescopic rod, and the end of the positioning plate is fixedly connected to a manual hydraulic pump, and the inner wall of the concrete revetment is slid up and down and connected with a gravity positioning block.

[0014] Optionally, a plurality of gravity positioning blocks are provided and are equidistantly distributed in a straight line along the spring telescopic rod, and the distance between two adjacent gravity positioning blocks is the same as the thickness of the positioning plate.

[0015] Optionally, a water level portion is provided inside the concrete revetment, and the water level portion includes a guide block, the guide block is fixedly mounted on the top of the concrete revetment, a telescopic guide rod is fixedly mounted on the bottom of the extended protective plate, the extended protective plate slides up and down along the inner wall of the guide block, a steel cable is fixedly mounted on the top of the extended protective plate, a counterweight block is fixedly mounted on the end of the steel cable, a buoyancy tube is fixedly mounted on the inner wall of the concrete revetment, and the buoyancy block is fixedly connected to the counterweight block via the steel cable.

[0016] Optionally, the top of the guide block is rotatably connected to a guide wheel, the steel cable slides along the guide wheel, the end of the buoyancy tube extends from the side of the concrete revetment, and the buoyancy tube is inclined along the direction of water flow.

[0017] A revetment method for a hydraulic structure of a revetment project is applied to the above-mentioned hydraulic structure of a revetment project, and the steps are as follows:

[0018] S1. First, due to the different water levels during dry and flood seasons, the buoyancy tube forms a connecting vessel with the water in the river. The buoyancy block changes height according to the water level. The buoyancy block uses a counterweight to pull the steel cable, raising the extended protection plate so that the length of the impact plate immersed in the water remains the same.

[0019] S2. Since the buoyancy tube is tilted along the direction of water flow, obstacles in the water are prevented from entering the interior of the buoyancy tube. The buoyancy tube acts as a narrow space, in which the water fluctuation is small, thus avoiding the constant change of the water level height within the buoyancy tube;

[0020] S3. The impact plate rotates as it is impacted by the water flow. The greater the impact force, the greater the impact plate's rotation angle. The impact plate uses a pair of gears to drive the toothed plate, pushing the push rod and manual hydraulic pump. The manual hydraulic pump causes the hydraulic rod to push the stop block, which pushes out the push rod. The push rod increases the bending angle of the upper half of the revetment steel plate, increasing the force of the water backflow, so that the impact water and the backflow water offset each other.

[0021] S4. The stop block adopts a stepped structure, dividing the push rod into three lengths. The flat surface on the fixed compartment supports the push rod to prevent the push rod from pushing the stop block when the revetment steel plate is impacted.

[0022] S5. When the spring telescopic rod pushes the positioning plate, the positioning plate rests on the gravity positioning block, thereby fixing the length of the manual hydraulic pump and preventing the manual hydraulic pump from continuously extending and retracting due to water fluctuations, which would cause wear. At the same time, the gravity positioning block limits the positioning plate, preventing the push rod from stopping at the inclined surface of the block, making it impossible to effectively position the push rod.

[0023] Compared with the prior art, the present invention has the following beneficial technical effects:

[0024] 1. In the present invention, when the impact force of the water flow is large, the larger the rotation angle of the impact plate and the longer the extension length of the top rod, the larger the bending angle of the bank protection steel plate and the greater the water force of the backflow, thereby increasing the flow force of the backflow water and offsetting the impact force of the water in the river bank; the smaller the impact force of the water flow, the smaller the rotation angle of the impact plate and the shorter the extension length, thereby reducing the bending angle of the bank protection steel plate and the water force of the backflow, thereby reducing the flow force of the backflow water and preventing the backflow water from causing sediment deposition on the bank.

[0025] 2. In the present invention, the support block adopts a stepped structure, which divides the push rod into three lengths, and the flat part on the fixed bin supports the push rod to prevent the impact force from being transmitted to the hydraulic rod by the push rod after the revetment steel plate is impacted. In the process of the spring telescopic rod pushing the positioning plate, the positioning plate is against the gravity positioning block, thereby fixing the length of the manual hydraulic pump, preventing the manual hydraulic pump from being continuously extended and retracted due to water fluctuations, and preventing the manual hydraulic pump and hydraulic rod from being worn due to long-term stress, thereby improving the service life of the manual hydraulic pump and hydraulic rod.

[0026] 3. The present invention forms a communicating vessel with the water in the river channel through the buoyancy tube. The buoyancy block changes in height due to the influence of the water level. The buoyancy block uses the counterweight block to pull the steel cable to raise the extended protection plate, so that the length of the impact plate immersed in the water is the same, avoiding the difference in the length of the impact plate immersed in the water, which affects the length of the top rod extended, that is, the different curvature of the bank protection steel plate, which affects the strength of the backflow water.

[0037] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention.

[0039] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0040] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0042] Example 1: This example proposes a hydraulic structure for a bank protection project, such as Figure 1 As shown, it includes a stepped concrete revetment 1, on the platform of which a revetment steel plate 2 for withstanding water impact is fixedly installed. The revetment steel plate 2 adopts a plate structure made of spring steel, and the side of the revetment steel plate 2 is provided with a plurality of guide grooves 3 distributed equidistantly along a straight line.

[0043] The revetment steel plate 2 is divided into two parts, the lower half of which rests against the vertical surface of the concrete revetment 1, while the upper half is inclined. The revetment steel plate 2 is used to divert water. When the revetment steel plate 2 is impacted, water flows back along the revetment steel plate 2, thereby offsetting the water impacting the revetment steel plate 2 and reducing the impact force on the revetment steel plate 2, thereby reducing the impact force on the riverbank.

[0044] like Figures 2 to 4 As shown, a return portion 4 is provided on the top of the concrete revetment 1, and the return portion 4 includes an extended protective plate 41, and the inner wall of the extended protective plate 41 is rotatably connected to the impact plate 42, and a manual hydraulic pump 46 is fixedly installed inside the extended protective plate 41, and a transmission member is provided between the manual hydraulic pump 46 and the impact plate 42, and the transmission member includes a pair of gears 43, and a pair of gears 43 is fixedly installed at the rotating shaft of the impact plate 42, and the pair of gears 43 includes two mutually meshing gears, one of which is fixedly connected to the rotating shaft of the impact plate 42, and a tooth plate 44 is slidably connected to the inner wall of the extended protective plate 41, and the other gear is meshed with the tooth plate 44, and a push rod 45 is fixedly installed on the end of the tooth plate 44, and a buffer is provided between the push rod 45 and the manual hydraulic pump 46.

[0045] like Figure 9 As shown, the extended protection plate 41 acts as an extension to prevent backflow water from impacting the impact plate 42. The impact of the water on the impact plate 42 causes it to rotate. The greater the impact of the water, the greater the angle of rotation of the impact plate 42. The impact plate 42 uses the gear 43 to drive the toothed plate 44 to move the push rod 45 and the manual hydraulic pump 46. The manual hydraulic pump 46 is connected to a hydraulic rod 47 fixed inside the concrete revetment 1 through a hydraulic pipe. A push rod 48 is slidably connected to the interior of the concrete revetment 1. The end of the push rod 48 is slidably connected to the revetment steel plate 2 to prevent the push rod 48 and the revetment steel plate 2 from getting stuck.

[0046] The manual hydraulic pump 46 causes the hydraulic rod 47 to push the block 52, and the block 52 pushes out the push rod 48. The push rod 48 increases the bending angle of the upper half of the revetment steel plate 2, increases the water backflow force, and offsets the impact of the water flow and the force of the backflow water.

[0047] The impact plate 42 is rotated by the impact of the water flow. The greater the impact force of the water flow, the greater the rotation angle of the impact plate 42. The impact plate 42 uses the gear 43 to drive the toothed plate 44 to move and push the push rod 45 and the manual hydraulic pump 46. The manual hydraulic pump 46 enables the hydraulic rod 47 to push the block 52. The block 52 pushes the push rod 48 out. The push rod 48 increases the bending angle of the upper part of the bank protection steel plate 2, increases the water backflow force, offsets the force of the impact water flow and the backflow water, and improves the service life.

[0048] The impact plate 42 is rotated by the impact of the water flow. The greater the impact force of the water flow, the greater the rotation angle of the impact plate 42, the longer the length of the manual hydraulic pump 46 being squeezed, the longer the moving distance of the hydraulic rod 47 and the push rod 48, the greater the extended length of the push rod 48, the greater the bending angle of the bank protection steel plate 2, and the greater the force of the backflow water.

[0049] The smaller the impact force of the water flow, the smaller the rotation angle of the impact plate 42, the shorter the length of the manual hydraulic pump 46 being squeezed, the shorter the moving distance of the hydraulic rod 47 and the push rod 48, the shorter the extended length of the push rod 48, the smaller the bending angle of the bank protection steel plate 2, and the smaller the backflow water force.

[0050] In this embodiment, when the impact force of the water flow is large, the larger the rotation angle of the impact plate 42 and the longer the extension length of the top rod 48, the larger the bending angle of the bank protection steel plate 2 and the greater the water force of the backflow, so as to increase the flow force of the backflow water and offset the impact force of the water in the river bank; the smaller the impact force of the water flow, the smaller the rotation angle of the impact plate 42 and the shorter the extension length of 48, the smaller the bending angle of the bank protection steel plate 2 and the smaller the water force of the backflow, so as to reduce the flow force of the backflow water and prevent the backflow water from causing sediment deposition on the bank.

[0051] Example 2, based on Example 1, this example proposes a hydraulic structure for a bank protection project, such as Figures 4 to 6 As shown, a buffer protection part 5 is provided inside the concrete revetment 1. The buffer protection part 5 includes a fixed bin 51 fixedly installed inside the concrete revetment 1. The inner wall of the fixed bin 51 is slidably connected with a stop block 52. The stop block 52 is fixedly installed at the end of the hydraulic rod 47. The end of the push rod 48 slides along the stop block 52. The stop block 52 adopts a stepped structure.

[0052] The stop block 52 adopts a stepped structure, dividing the push rod 48 into three lengths, and the flat part on the fixed chamber 51 supports the push rod 48 to prevent the push rod 48 from pushing the stop block 52 due to the impact force after the revetment steel plate 2 is impacted, thereby avoiding the manual hydraulic pump 46 and the hydraulic rod 47 from being subjected to long-term stress and causing wear, thereby improving the service life of the manual hydraulic pump 46 and the hydraulic rod 47.

[0053] like Figure 7 As shown, a guide cylinder 49 is fixedly installed on the outer wall of the fixed bin 51, and the outer wall of the top rod 48 is slidably connected to the guide cylinder 49. A plurality of revetment steel plates 2 are provided, and are laid end to end on the vertical surface of the concrete revetment 1. Two symmetrically distributed top rods 48 are provided on the side of each revetment steel plate 2.

[0054] A stepped groove 53 is provided on the stop block 52, and the end of the push rod 48 is rotatably connected to a roller 54. The stepped groove 53 and the roller 54 cooperate to reduce friction. The roller 54 rolls along the stepped groove 53, and the stepped groove 53 pulls the roller 54 back, that is, pulls the push rod 48 back.

[0055] The buffer includes a spring telescopic rod 55, which is fixedly mounted on the end of the push rod 45. A positioning plate 56 is fixedly mounted on the end of the spring telescopic rod 55. The end of the positioning plate 56 is fixedly connected to the manual hydraulic pump 46. The inner wall of the concrete revetment 1 is slidably connected to a gravity positioning block 57. A plurality of gravity positioning blocks 57 are provided, and are equidistantly distributed in a straight line along the spring telescopic rod 55. The spacing between two adjacent gravity positioning blocks 57 is the same as the thickness of the positioning plate 56.

[0056] Gravity-positioning blocks 57 act as obstacles to the movement of positioning plate 56. When positioning plate 56 moves between the two gravity-positioning blocks 57, the end of push rod 48 abuts the flat surface of stepped groove 53. After the spring-type telescopic rod 55 is fully compressed, it directly pushes positioning plate 56. While the spring-type telescopic rod 55 pushes positioning plate 56, positioning plate 56 abuts against gravity-positioning blocks 57, thereby fixing the length of manual hydraulic pump 46 and preventing wear and tear caused by water fluctuations that cause continuous expansion and contraction of manual hydraulic pump 46.

[0057] In this embodiment, the support block 52 adopts a stepped structure, dividing the push rod 48 into three lengths, and the flat part on the fixed chamber 51 supports the push rod 48 to prevent the impact force from being transmitted to the hydraulic rod 47 by the push rod 48 after the revetment steel plate 2 is impacted. In the process of the spring telescopic rod 55 pushing the positioning plate 56, the positioning plate 56 is against the gravity positioning block 57, thereby fixing the length of the manual hydraulic pump 46, preventing the manual hydraulic pump 46 from being continuously extended and retracted due to water fluctuations, and preventing the manual hydraulic pump 46 and the hydraulic rod 47 from being subjected to long-term stress and causing wear, thereby improving the service life of the manual hydraulic pump 46 and the hydraulic rod 47.

[0058] Example 3, based on the above-mentioned Example 1 or 2, this example proposes a hydraulic structure for a bank protection project, such as Figures 2 to 8 As shown, a water level portion 6 is provided inside the concrete revetment 1, and the water level portion 6 includes a guide block 61, which is fixedly mounted on the top of the concrete revetment 1, and a telescopic guide rod 62 is fixedly mounted on the bottom of the extension protection plate 41. The extension protection plate 41 slides up and down along the inner wall of the guide block 61, and a steel cable 63 is fixedly mounted on the top of the extension protection plate 41. A counterweight block 65 is fixedly mounted on the end of the steel cable 63. A buoyancy tube 67 is fixedly mounted on the inner wall of the concrete revetment 1, and the buoyancy block 66 is fixedly connected to the counterweight block 65 through the steel cable 63.

[0059] Due to the different water levels during the dry season and the flood season, a communicating vessel is formed with the water in the river channel through the buoyancy tube 67. The buoyancy block 66 is affected by the water level and its height changes. The buoyancy block 66 uses the counterweight block 65 to pull the steel cable 63 to raise the extended protection plate 41 so that the length of the impact plate 42 immersed in the water is the same.

[0060] When the water level in the river changes, the height of the buoyancy block 66 changes. The steel cable 63 and the counterweight block 65 cooperate to make the height of the extension protection plate 41 move the same as the height of the buoyancy block 66 changes, so that the length of the part of the impact plate 42 immersed in the water is always fixed.

[0061] The top of the guide block 61 is rotatably connected to a guide wheel 64 , and the steel cable 63 slides along the guide wheel 64 . The end of the buoyancy tube 67 extends from the side of the concrete revetment 1 , and the buoyancy tube 67 is tilted along the direction of the water flow.

[0062] Since the buoyancy tube 67 is inclined along the direction of water flow, obstacles in the water are prevented from entering the interior of the buoyancy tube 67. As a narrow space, the water fluctuation in the buoyancy tube 67 is small, which prevents the water level in the buoyancy tube 67 from constantly changing.

[0063] In this embodiment, a communicating vessel is formed with the water in the river channel through the buoyancy tube 67, and the buoyancy block 66 changes in height due to the influence of the water level. The buoyancy block 66 uses the counterweight block 65 to pull the steel cable 63 to raise the extended protection plate 41, so that the length of the impact plate 42 immersed in the water is the same, avoiding the length of the top rod 48 extended being affected by the different lengths of the impact plate 42 immersed in the water, that is, the different curvature of the bank protection steel plate 2, which causes the force of the backflow water to be affected.

[0064] A revetment method for a revetment engineering hydraulic structure is applied to the above-mentioned revetment engineering hydraulic structure, and the steps are as follows:

[0065] S1. First, due to the different water levels during dry and flood seasons, buoyancy tube 67 forms a communicating vessel with the water in the river channel. Buoyancy block 66 changes height due to the water level. Buoyancy block 66, using counterweight 65, pulls cable 63, raising extension plate 41 so that the length of impact plate 42 submerged in water remains the same.

[0066] S2. Since the buoyancy tube 67 is tilted along the direction of water flow, obstacles in the water are prevented from entering the interior of the buoyancy tube 67. The buoyancy tube 67 is a narrow space in which the water fluctuation is small, thus avoiding the constant change of the water level height within the buoyancy tube 67;

[0067] S3. The impact plate 42 rotates as it is impacted by the water flow. The greater the impact force, the greater the rotation angle of the impact plate 42. The impact plate 42 uses the gear 43 to drive the toothed plate 44 to move the push rod 45 and the manual hydraulic pump 46. The manual hydraulic pump 46 causes the hydraulic rod 47 to push the stop block 52. The stop block 52 pushes out the push rod 48. The push rod 48 increases the bending angle of the upper half of the revetment steel plate 2, increasing the force of the water backflow, so that the impact water flow and the backflow water offset each other.

[0068] S4 block 52 adopts a stepped structure, the push rod 48 is divided into three lengths, and the fixed compartment 51 on the flat portion supports the push rod 48, to avoid the revetment steel plate 2 after the impact, the impact force of the push rod 48 pushes the block 52;

[0069] S5. When the spring telescopic rod 55 pushes the positioning plate 56, the positioning plate 56 abuts against the gravity positioning block 57, thereby fixing the length of the manual hydraulic pump 46 and preventing the manual hydraulic pump 46 from continuously expanding and contracting due to water fluctuations, thereby causing wear. At the same time, the gravity positioning block 57 limits the positioning plate 56, preventing the push rod 48 from stopping at the inclined surface of the abutment block 52, making it impossible to effectively position the push rod 48.

[0070] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.

9. The hydraulic structure of a bank protection project according to claim 8, characterized in that: The top of the guide block (61) is rotatably connected to a guide wheel (64), the steel cable (63) slides along the guide wheel (64), the end of the buoyancy tube (67) extends from the side of the concrete revetment (1), and the buoyancy tube (67) is inclined along the direction of water flow.

10. A revetment method for a hydraulic structure of a revetment project, applied to the hydraulic structure of a revetment project of claim 9, comprising the following steps: S1. First, due to the different water levels during the dry season and the flood season, the buoyancy tube (67) forms a communicating vessel with the water in the river channel. The buoyancy block (66) is affected by the water level and changes in height. The buoyancy block (66) uses the counterweight block (65) to pull the steel cable (63) to raise the extension protection plate (41) so that the length of the impact plate (42) immersed in the water is the same; S2. Since the buoyancy tube (67) is inclined along the direction of the water flow, obstacles in the water are prevented from entering the interior of the buoyancy tube (67). The buoyancy tube (67) is a narrow space in which the water fluctuation is small, thus preventing the water level in the buoyancy tube (67) from constantly changing. S3. The impact plate (42) is subjected to the impact of the water flow and rotates. The greater the impact force of the water flow, the greater the rotation angle of the impact plate (42). The impact plate (42) uses the gear (43) to drive the toothed plate (44) to move and push the push rod (45) and the manual hydraulic pump (46). The manual hydraulic pump (46) causes the hydraulic rod (47) to push the block (52). The block (52) pushes the push rod (48). The push rod (48) increases the bending angle of the upper half of the revetment steel plate (2), increases the water backflow force, and offsets the force of the impact water flow and the backflow water. S4. The block (52) adopts a stepped structure, the push rod (48) is divided into three lengths, and the upper plane portion of the fixed chamber (51) supports the push rod (48) to prevent the revetment steel plate (2) from being impacted and the impact force causing the push rod (48) to push the block (52); S5. During the process of the spring telescopic rod (55) pushing the positioning plate (56), the positioning plate (56) abuts against the gravity positioning block (57), thereby fixing the length of the manual hydraulic pump (46) and preventing the manual hydraulic pump (46) from being continuously extended and retracted due to water fluctuations, thereby causing wear. At the same time, the gravity positioning block (57) limits the positioning plate (56), preventing the push rod (48) from stopping at the inclined surface of the abutment block (52), thereby failing to effectively position the push rod (48).
