Description

Technical Field

[0001] This invention relates to the field of river ecological management technology, specifically to protective structures and methods for preventing erosion of concave riverbanks. Background Technology

[0002] Riverbank erosion is a significant mode of lateral river evolution, occurring along the banks of almost all rivers. Eroded riverbanks face ecological degradation and can even lead to bank collapses and major accidents. Natural rivers are almost always meandering, and the unique flow characteristics of river bends make the slopes of concave banks more susceptible to erosion. Therefore, finding effective methods to prevent and control erosion of concave banks in river bends is of great importance for soil and water conservation.

[0003] Currently, in the process of river management, such as water and soil conservation and prevention of riverbank erosion, the lack of targeted engineering measures for concave bank erosion makes it easy for silt to accumulate on the convex bank, leading to narrowing of the river channel. This, in turn, accelerates the river flow, which in turn increases the impact of the water flow on the concave bank, creating a vicious cycle and increasing the maintenance cost of the riverbank. Summary of the Invention

[0004] The purpose of this invention is to provide a protective structure and method for preventing erosion of concave riverbanks, aiming to solve the problem in the prior art where narrowing of the river channel accelerates the water flow, leading to increased impact of the water flow on the concave riverbank and increased maintenance costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: the protective structure and method for preventing erosion of the concave bank of a river includes a fixed support frame extending in the left-right direction. The fixed support frame is a portal frame structure and is installed on the riverbank near the concave bank.

[0006] The fixed support frame is equipped with a sliding block that can slide left and right along the fixed support frame. The fixed support frame is equipped with a translation mechanism, which is used to slide the sliding block along the length of the fixed support frame. A lifting mechanism is fixedly installed on the side of the sliding block away from the fixed support frame. The lower end of the rope of the lifting mechanism is fixedly connected to the rear top of the mounting plate.

[0007] The bottom of the mounting plate is equipped with an arc-shaped block, which is a downward convex arc-shaped structure. The mounting plate can rotate left and right to rest against the riverbed, which is a downward concave arc-shaped structure.

[0008] A hinge seat is fixedly provided in the middle of the rear side of the mounting plate. The hinge seat is hinged to the middle of the bottom of the protective plate. The protective plate has an arc-shaped plate structure and can swing up and down.

[0009] A hydraulic swing mechanism is fixedly installed on the rear side of the mounting plate. The hydraulic swing mechanism is connected to the protective plate and is used to drive the protective plate to swing up and down.

[0010] Preferably, the rear side of the fixed support frame is provided with a limiting groove that is open to the left and right and faces backward, and the vertical cross section of the limiting groove is trapezoidal.

[0011] Preferably, the translation mechanism includes a first lead screw extending in the left-right direction and a second drive device fixedly mounted on one of the fixed support frames;

[0012] The output end of the second drive device is fixedly connected to the left end of the first lead screw, and the end of the first lead screw away from the second drive device is rotatably connected to the fixed support frame.

[0013] The sliding block is slidably inserted into the limiting groove. The sliding block has a first threaded hole that is open to the left and right. The first lead screw is threadedly connected to the first threaded hole. The first lead screw and the first threaded hole cooperate with each other to drive the sliding block to move left and right along the limiting groove.

[0014] Preferably, the rear side of the mounting plate is fixed with multiple sets of left-right spaced fixing seat assemblies;

[0015] The mounting bracket assembly includes a left connecting bracket and a right connecting bracket, which are arranged in parallel.

[0016] Preferably, the hydraulic oscillation power mechanism includes a rotating rod assembly and an oscillating rod extending in the front-to-back direction;

[0017] The left and right connecting seats of each group are rotatably connected to the rotating rod assembly, and the end of the swing rod away from the rotating rod assembly is hinged to the protective plate.

[0018] The rotating rod assembly includes two short rods spaced apart from each other and a connecting rod fixed between the two short rods. The connecting rod is hinged to the swing rod.

[0019] The two adjacent rotating rod assemblies are fixedly connected. The left side of the leftmost rotating rod assembly is fixedly connected to the left connecting seat. The upper gear is provided above the lower gear. The upper gear and the lower gear mesh with each other.

[0020] A transmission rod extending in the left-right direction is fixedly provided on the left side of the lower gear, and a fan blade is provided on the left side of the transmission rod.

[0021] Preferably, a vertical rod extending in the vertical direction is fixedly connected to the left side of the transmission rod via a universal joint, and a horizontal rod extending in the left-right direction is fixedly connected to the upper end of the vertical rod via a universal joint. The horizontal rod is fixedly connected to the fan blade, and the fan blade is arranged parallel to the swing power mechanism. The bottom of the fan blade is higher than the bottom of the protective plate.

[0022] A support plate is fixed on the left side of the mounting plate. The support plate has a rotating hole that is open from top to bottom. The vertical rod is slidably inserted into the rotating hole. Multiple protective plates swing in a wave shape under the action of the fan blades.

[0023] Preferably, the rear side of the protective plate is provided with a detachable buffer component, the protective plate is provided with multiple bolt grooves spaced vertically, and the buffer component is provided with multiple bolt holes spaced vertically and open from front to back.

[0024] A bolt is inserted into the bolt hole, and the bolt is threaded into the bolt groove.

[0025] The preferred method is as follows:

[0026] S1, Insert and fix the fixed support frame to the riverbank;

[0027] S2, control the second drive device so that the output shaft of the second drive device drives the first lead screw, which moves the sliding block left and right along the limit groove under the action of the first lead screw, in order to adjust the position of the sliding block;

[0028] S3, the buffer component is fixedly installed on the protective plate with bolts;

[0029] S4, control the lifting mechanism to lower the installation plate into the riverbed by laying out the line;

[0030] S5, water flows through the fan blades, which indirectly drives the transmission rod to rotate. When the transmission rod rotates, it drives the lower gear to rotate, the lower gear drives the upper gear to rotate, and the upper gear drives the rotating rod assembly to rotate.

[0031] S6, When the rotating rod assembly rotates, it can drive multiple swing rods to swing in a wave-like manner;

[0032] S7. When the buffer component is damaged, the removable bolts can be used to remove the damaged buffer component from the protective plate, and then a new buffer component can be replaced.

[0033] The beneficial effects are: 1. By setting up the hydraulic swing power mechanism, when the river is small, the installation plate can be lowered to the bottom of the riverbed to protect the concave bank of the river. When the river is large, the installation plate can be raised so that the protective plate and buffer components can strengthen the protection of the concave bank and prevent the river from eroding the concave bank.

[0034] 2. The flow of water allows the fan blades to rotate within the river. As the fan blades rotate, they indirectly drive the lower gears to rotate. Since the upper and lower gears mesh with each other, they can drive the rotating rod assembly to rotate, thereby causing the protective plate and buffer components to swing up and down to protect the concave bank.

[0043] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0044] like Figures 1-7 As shown, the protective structure and method for preventing erosion of the concave bank of a river are described. First, the position and height of the hydraulic swing mechanism are adjusted so that it can withstand the impact of the river and prevent the river from eroding the concave bank. Moreover, it can be adjusted according to the size of the river to improve the protective effect. Specifically, it includes a fixed support frame 1 extending in the left and right direction (the bottom of the fixed support frame 1 is fixedly provided with a fixed seat, which can be fixed to the riverbank by bolts to improve the stability of the fixed support frame 1). The fixed support frame 1 is a portal structure and is set on the riverbank near the concave bank. The fixed support frame 1 is fixedly inserted into the riverbank so that the hydraulic swing mechanism can be lowered into the river.

[0045] By controlling the start of the second drive device 12, the output shaft of the second drive device 12 can drive the first lead screw 11 to rotate, so as to adjust the position of the sliding block 3, and then adjust the position of the hydraulic swing power mechanism to improve the protection effect. Specifically, a limiting groove 10 with left and right open sides and rearward opening is provided on the rear side of the fixed support frame 1. The vertical cross section of the limiting groove 10 is trapezoidal. The trapezoidal setting of the vertical cross section of the limiting groove 10 can prevent the sliding block 3 from disengaging from the limiting groove 10. Moreover, when the sliding block 3 slides along the limiting groove 10 under the action of the first lead screw 11, the sliding effect can also be improved.

[0046] The fixed support frame 1 is equipped with a sliding block 3 that can slide left and right along the fixed support frame 1. The fixed support frame 1 is equipped with a translation mechanism, which is used to slide the sliding block 3 along the length direction of the fixed support frame 1. A lifting mechanism 2 (the lifting mechanism 2 is a hook device, which can drive the mounting plate 5 to move together when the lifting mechanism 2 is moving) is fixedly installed on the side of the sliding block 3 away from the fixed support frame 1. The lower end of the rope of the lifting mechanism 2 is fixedly connected to the top rear side of the mounting plate 5. Through the setting of the hydraulic swing power mechanism, when the river is small, the mounting plate 5 can be lowered to the bottom of the riverbed to protect the concave bank of the river. When the river is large, the mounting plate 5 can be raised so that the protective plate 7 and the buffer component 8 can strengthen the protection of the concave bank and prevent the river from eroding the concave bank.

[0047] The translation mechanism includes a first lead screw 11 extending in the left-right direction and a second drive device 12 (the second drive device 12 is a second drive self-locking motor) fixedly mounted on one of the fixed support frames 1.

[0048] The output end of the second drive device 12 is fixedly connected to the left end of the first lead screw 11. The end of the first lead screw 11 away from the second drive device 12 is rotatably connected to the fixed support frame 1. When the second drive device 12 is started, it can drive the first lead screw 11 to rotate, so that the sliding block 3 slides along the limit groove 10 to adjust the position of the lifting mechanism 2, thereby adjusting the position of the mounting plate 5.

[0049] The sliding block 3 is slidably inserted into the limiting groove 10. The sliding block 3 has a first threaded hole that is open to the left and right. The first lead screw 11 is threadedly connected to the first threaded hole. The first lead screw 11 and the first threaded hole cooperate with each other to drive the sliding block 3 to move left and right along the limiting groove 10.

[0050] The bottom of the mounting plate 5 is provided with an arc-shaped block, which is a downward convex arc-shaped structure. The mounting plate 5 can rotate left and right to abut against the riverbed, which is a downward concave arc-shaped structure. The bottom of the mounting plate 5 is arc-shaped so that it can be attached to the riverbed so that the protective plate 7 can protect the river.

[0051] When the protective plate 7 is in use, it can be made to undulate to protect the concave bank. Moreover, the mounting plate 5 can be raised and lowered and can be adjusted according to the size of the river. Specifically, multiple sets of left and right spaced fixing seat assemblies 16 are fixed on the rear side of the mounting plate 5.

[0052] By setting the fixed base assembly 16, the swing rod 27 can drive the rotating rod assembly 17 to rotate together when it rotates. Since the swing rod 27 is hinged to the connecting rod 1702, the swing rod 27 can rotate so that the protective plate 7 swings in a wave-like manner. Specifically, the fixed base assembly 16 includes a left connecting base 1601 and a right connecting base 1602, which are arranged in parallel.

[0053] The hydraulic oscillation power mechanism includes a rotating rod assembly 17 and an oscillating rod 27 extending in the front-to-back direction.

[0054] The left connecting seat 1601 and the right connecting seat 1602 of each group are rotatably connected to the rotating rod assembly 17. The end of the swing rod 27 away from the rotating rod assembly 17 is hinged to the protective plate 7. When the rotating rod assembly 17 rotates, it can drive the adjacent rotating rod assembly 17 to rotate, so as to drive the swing rod 27 to swing in a wave-like manner, thereby causing the protective plate 7 to swing in a wave-like manner. Moreover, when the protective plate 7 swings, it can protect the concave bank.

[0055] The rotating rod assembly 17 includes two short rods 1701 spaced apart from each other and a connecting rod 1702 fixed between the two short rods 1701. The connecting rod 1702 is hinged to the swing rod 27.

[0056] Two adjacent rotating rod assemblies 17 are fixedly connected. The leftmost rotating rod assembly 17 has an upper gear 24 fixedly connected to the left connecting seat 1601. The upper gear 24 is located above the lower gear 25. The upper gear 24 and the lower gear 25 mesh with each other. When the transmission rod 20 rotates, it can drive the lower gear 25 to rotate. Since the upper gear 24 and the lower gear 25 mesh with each other, the upper gear 24 can be driven to rotate. When the upper gear 24 rotates, it can drive one of the rotating rod assemblies 17 to rotate.

[0057] A transmission rod 20 extending in the left-right direction is fixedly provided on the left side of the lower gear 25. A fan blade 21 is provided on the left side of the transmission rod 20. Since the transmission rod 20 and the vertical rod are connected to each other through a universal joint, the fan blade 21 can drive the transmission rod 20 to rotate when it rotates.

[0058] A vertical rod extending in the vertical direction is fixedly connected to the left side of the transmission rod 20 via a universal joint. A horizontal rod extending in the left-right direction is fixedly connected to the upper end of the vertical rod via a universal joint. The horizontal rod is fixedly connected to the fan blade 21. When the river flows through, it can drive the fan blade 21 to rotate. When the fan blade 21 rotates, it can drive the horizontal rod to rotate. The fan blade 21 is arranged parallel to the swing power mechanism. The bottom of the fan blade 21 is higher than the bottom of the protective plate 7. The fan blade 21 is located in the upper part of the river.

[0059] A support plate is fixedly installed on the left side of the mounting plate 5. The support plate has a rotating hole that is open from top to bottom. The vertical rod is slidably inserted into the rotating hole. Multiple protective plates 7 swing in a wave shape under the action of the fan blade 21.

[0060] A hinge seat 6 is fixedly provided at the middle of the rear side of the mounting plate 5. The hinge seat 6 is hinged to the middle of the bottom of the protective plate 7. The protective plate 7 has an arc-shaped plate structure and can swing up and down. When the protective plate 7 rotates, it can rotate around the hinge seat 6.

[0061] A hydraulic swing power mechanism is fixedly installed on the rear side of the mounting plate 5. The hydraulic swing power mechanism is connected to the protective plate 7 and is used to drive the protective plate 7 to swing up and down.

[0062] The rear side of the protective plate 7 is provided with a detachable buffer component 8 (the buffer component 8 is made of foam). The protective plate 7 has multiple bolt grooves spaced vertically, and the buffer component 8 has multiple bolt holes spaced vertically and open from front to back. During installation, the buffer component 8 can be installed on the protective plate 7 so that the impact force on the protective plate 7 can be reduced when the river rushes in.

[0063] Bolt 26 is inserted into the bolt hole and threaded into the bolt groove. When the buffer component 8 is damaged, the detachable bolt 26 can remove the damaged buffer component 8 from the protective plate 7 and then replace it with a new buffer component 8.

[0064] Working principle: The specific operation is as follows:

[0065] S1, the fixed support frame 1 is inserted and fixed to the riverbank (the bottom of the fixed support frame 1 is fixed with a fixed seat, which can be fixed to the riverbank with bolts to improve the stability of the fixed support frame 1).

[0066] S2, control the second drive device 12 so that the output shaft of the second drive device 12 drives the first lead screw 11 to move the sliding block 3 left and right along the limiting groove 10 under the action of the first lead screw 11, so as to adjust the position of the sliding block 3.

[0067] S3, the buffer component 8 is fixedly installed on the protective plate 7 by bolts 26 (bolts 26 are inserted through the bolt holes and the bolts 26 are threadedly connected to the bolt grooves).

[0068] S4, control the lifting mechanism 2 to lower the installation plate 5 into the riverbed (the hydraulic swing mechanism allows the installation plate 5 to be lowered to the bottom of the riverbed when the river is small, thus protecting the concave bank; when the river is large, the installation plate 5 can be raised, allowing the protective plate 7 and buffer member 8 to strengthen the protection of the concave bank and prevent the river from eroding it).

[0069] S5, water flows through the fan blade 21, which indirectly drives the transmission rod 20 to rotate. When the transmission rod 20 rotates, it drives the lower gear 25 to rotate. The lower gear 25 drives the upper gear 24 to rotate. The upper gear 24 drives the rotating rod assembly 17 to rotate.

[0070] S6, When the rotating rod assembly 17 rotates, it can drive multiple swing rods 27 to swing in a wave-like manner;

[0071] S7, when the buffer component 8 is damaged, the removable bolt 26 removes the damaged buffer component 8 from the protective plate 7, and then replaces the new buffer component 8.

[0072] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
