Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a bank protection and reinforcement device for soil and water conservation. Background Technology

[0002] Soil and water conservation refers to the prevention and control of soil erosion caused by natural factors and human activities through engineering measures, vegetation measures, and agricultural technology measures, in order to protect and rationally utilize soil and water resources, maintain and improve land productivity, and promote the sustainability of social and economic development and the ecological environment.

[0003] During the construction of water conservancy projects, soil and water conservation work is usually required, which involves reinforcing the dikes along the riverbanks. Currently, common reinforcement methods include stacking stones along the dike edges or installing steel plates on the dike surface. The former method can cause the stones to be washed away in turbulent water, thus affecting the reinforcement effect. While the latter method increases the dike's resistance to water flow impact to some extent, the surface of the steel plate is relatively smooth compared to the dike surface. When large waves from the water flow impact the steel plate, they may splash off the steel plate surface and fall onto the top of the dike, impacting the soil on the top of the dike and causing soil erosion. Summary of the Invention

[0004] The purpose of this invention is to provide a bank protection reinforcement device for soil and water conservation, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A bank protection and reinforcement device for soil and water conservation includes a dike, and further includes: An impact-resistant steel plate is installed on the slope of the dam. Multiple buffer connectors are provided between the impact-resistant steel plate and the slope of the dam. The buffer connectors are used to buffer the movement of the impact-resistant steel plate toward the slope of the dam. Two rotating plates are sequentially hinged from top to bottom to the wave-facing surface of the impact-resistant steel plate, and a baffle is vertically fixed to the lower end of the rotating plates.

[0006] Furthermore, an arc-shaped segment is fixedly connected at the connection between the baffle and the flip plate.

[0007] Furthermore, a hinge rod is hinged between the two flip plates, and a through groove is provided on the surface of the flip plate to allow the hinge rod to pass freely.

[0008] Furthermore, a first swing plate is hinged to the lower side of the impact-resistant steel plate, and a second swing plate is fixed to the upper end of the first swing plate. The first swing plate and the second swing plate form an angle, and a connecting rod is hinged between the first swing plate and one of the flip plates.

[0009] Furthermore, a buffer cavity is formed between the impact-resistant steel plate and the dam slope. A communication opening is provided on the surface of the impact-resistant steel plate. A cover plate is provided on the impact-resistant steel plate. A closing drive is provided between the cover plate and the impact-resistant steel plate. The closing drive is used to drive the cover plate to move towards the wave-facing side of the impact-resistant steel plate and close the communication opening when the second swing plate swings towards the impact-resistant steel plate.

[0010] Furthermore, the closing drive includes a pressing part fixed to the side of the cover plate facing the second swing plate. The pressing part is used in conjunction with the second swing plate. A guide post is vertically fixed to the surface of the impact-resistant steel plate. A guide hole is opened on the surface of the cover plate to allow the guide post to pass freely. A pulling unit is provided on the guide post. The pulling unit is used to drive the cover plate to move away from the impact-resistant steel plate, so that the pressing part abuts against the surface of the second swing plate.

[0011] Furthermore, the pulling unit includes a locking nut fixedly sleeved on the end of the guide post away from the impact-resistant steel plate, and a tension spring is wound around the guide post, with both ends of the tension spring fixed to the end face of the locking nut and the surface of the cover plate, respectively.

[0012] Furthermore, the buffer connector includes a fixed beam fixed to the other side of the impact-resistant steel plate, an expansion bolt is vertically inserted through the fixed beam, a bolt sleeve is embedded in the dam, the expansion bolt is inserted into the bolt sleeve, one end of the expansion bolt protruding from the dam is inserted through the fixed beam, and a locking nut is sleeved on the other end of the expansion bolt inserted into the fixed beam. An elastic unit is provided between the fixed beam and the dam, and the elastic unit is used to drive the fixed beam to move away from the dam.

[0013] Furthermore, the elastic unit includes a washer fixed to the bolt sleeve at one end of the dam, and a spring is wrapped around the periphery of the expansion bolt. The two ends of the spring in the direction of the elastic force elastically abut against the washer and the fixed beam, respectively.

[0014] Furthermore, the length direction of the fixed beam is consistent with the length direction of the impact-resistant steel plate and spans the length direction of the fixed beam.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the impact-resistant steel plate withstands the impact of water flow and waves. The flip plate, baffle, and impact-resistant steel plate form a stepped structure, and the tip of the stepped structure faces the direction of water flow. When the water flow impacts the impact-resistant steel plate, the tip of the stepped structure will disperse the water flow, reducing the local impact of water flow on the impact-resistant steel plate. In addition, the baffle has a blocking effect on the water flow, so that when the water flow impacts the impact-resistant steel plate, it will not splash upward along the surface of the impact-resistant steel plate, thereby preventing the water flow from impacting the soil on the top surface of the dam. 2. In this invention, by setting a first swing plate and a second swing plate, when the water flow is large, the water flow will generate a large impact force on the second swing plate, causing the second swing plate to swing towards the impact-resistant steel plate. This causes the connecting rod to drive the flip plate to flip upward, which in turn causes the stepped structure to flip upward. The baffle is no longer in contact with the surface of the impact-resistant steel plate. In this way, when the water flow is large, the water flow and waves will flow along the surface of the impact-resistant steel plate into the area between the flip plate and the baffle, avoiding the large impact force of the large water flow and waves, which would cause the water flow and waves to impact the soil on the top surface of the dam. In addition, when the water flow or waves flow away from the dam, the second swing plate will move in the opposite direction with the water flow, causing the flip plate to flip downward, which in turn causes the baffle to flip downward simultaneously. This allows the baffle to drive the floating garbage on the water surface into the inner side of the stepped structure, making it easier to collect and process the floating garbage later. 3. In this invention, by setting a spring to generate an elastic resisting force on the fixed beam, the impact-resistant steel plate can compress the spring and move slightly towards the dam when impacted by water flow, thereby buffering the movement of the impact-resistant steel plate. By setting a connecting port and a cover plate, when the water flow is large, the second swing plate will swing towards the impact-resistant steel plate and squeeze the extrusion part, causing the extrusion part to drive the cover plate to overcome the tension of the tension spring on the cover plate, thereby making the cover plate fit against the surface of the impact-resistant steel plate and closing the connecting port. At this time, the water in the buffer cavity can provide an auxiliary buffering effect when the impact-resistant steel plate moves towards the dam. When the water flow or waves are small, the connecting port is in an open state, allowing water to flow inside and outside the buffer cavity, thereby allowing the impact-resistant steel plate to compress the spring, thus buffering the water flow and waves.

[0018] 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.

[0019] Please see Figure 1 - Figure 6 This invention provides a technical solution: a bank protection reinforcement device for soil and water conservation, comprising a dike 1, the slope of which is in contact with the riverbank water, and impact-resistant steel plates 2 installed on the slope of the dike 1. The lower side of the impact-resistant steel plates 2 extends into the shallow surface layer of the silt at the bottom of the water. Multiple impact-resistant steel plates 2 can be arranged in a straight series on the slope of the dike 1, with the ends of adjacent impact-resistant steel plates 2 abutting each other. Three U-shaped fixing beams 13 are welded from top to bottom on the side of the impact-resistant steel plates 2 facing the dike 1, and expansion bolts 20 (e.g., ...) are vertically inserted through the fixing beams 13. Figure 6As shown), the expansion bolt 20 slides freely on the fixed beam 13. A bolt sleeve 12 is embedded inside the dam 1, and the expansion bolt 20 is inserted into the bolt sleeve 12. A locking nut 22 is threaded onto one end of the expansion bolt 20 that passes through the open portion of the fixed beam 13. The locking nut 22 is used to limit the sliding of the fixed beam 13 on the expansion bolt 20. A washer 19 is welded to the end of the bolt sleeve 12 that protrudes from the slope of the dam 1. A spring 21 is wound around the periphery of the expansion bolt 20, and the two ends of the spring 21 elastically extend from the two ends in the direction of the spring force. The top washer 19 and the fixing beam 13 are parallel to the surface of the impact-resistant steel plate 2 and the slope of the dam 1. When the water flow and waves impact the surface of the impact-resistant steel plate 2, the impact-resistant steel plate 2 will move towards the dam 1, causing the fixing beam 13 to compress the spring 21, thereby buffering the movement of the impact-resistant steel plate 2. The length direction of the fixing beam 13 is consistent with the length direction of the impact-resistant steel plate 2, and the fixing beam 13 spans both sides of the length direction of the impact-resistant steel plate 2, so that the fixing beam 13 has a certain degree of reinforcement effect on the impact-resistant steel plate 2. Two tilting plates 4 are hinged sequentially from top to bottom on the wave-facing surface of the impact-resistant steel plate 2. The upper tilting plate 4 is installed above the water level in the river (refer to the water level during flood season), while the lower tilting plate 4 is installed at approximately the same plane as the water level in the river (refer to the water level during drought season). A baffle 6 is vertically fixed to the lower end of the tilting plate 4. When the end of the baffle 6 away from the tilting plate 4 contacts the surface of the impact-resistant steel plate 2, the baffle 6, the tilting plate 4, and the impact-resistant steel plate 2 form a stepped structure, with the tip of the stepped structure facing the direction of water flow. In this way, when water flow or waves impact the surface of the impact-resistant steel plate 2, the stepped structure can cut and disperse the water flow. A hinge rod 5 is hinged between the two tilting plates 4. The surface of the lower flip plate 4 is provided with a through groove 23 for the hinge rod 5 to pass freely. The lower side of the impact-resistant steel plate 2 is hinged to a first swing plate 11, and the upper end of the first swing plate 11 is fixed to a second swing plate 9. The first swing plate 11 and the second swing plate 9 are at an angle, and the second swing plate 9 is vertical in the initial state. The first swing plate 11 and one of the flip plates 4 are hinged together by a connecting rod 7. When the second swing plate 9 rotates along the hinge point between the first swing plate 11 and the impact-resistant steel plate 2, the first swing plate 11 will swing, and the connecting rod 7 will drive the flip plate 4 to flip. The two flip plates 4 are hinged together by a hinge rod 5, which enables the two flip plates 4 to flip synchronously. The connection between the baffle 6 and the flip plate 4 is fixed with an arc-shaped segment 14.

[0020] Because expansion bolts 20 and fixing beams 13 are installed between the impact-resistant steel plate 2 and the dam 1, the impact-resistant steel plate 2 does not directly contact the slope of the dam 1, forming a buffer cavity 3 between them. The lower side of the impact-resistant steel plate 2 extends to the upper layer of the silt at the bottom of the water, and the impact-resistant steel plates 2 are installed on the dam 1 in a series manner (or in other words, multiple impact-resistant steel plates 2 are arranged side by side in a line). The edges of two impact-resistant steel plates 2 contact the inner wall of the dam 1, thus making the buffer cavity 3 a partially closed structure. In addition, the surface of the impact-resistant steel plate 2 has a connecting opening 15 (such as...). Figure 3 As shown), a cover plate 10 is provided on the impact-resistant steel plate 2. A guide post 18 is vertically fixed to the surface of the impact-resistant steel plate 2. A guide hole is opened on the surface of the cover plate 10 to allow the guide post 18 to pass freely, so that the cover plate 10 slides on the guide post 18. When the cover plate 10 is in contact with the surface of the impact-resistant steel plate 2, it can close the communication port 15. A pressing part 8 (such as...) is fixed to the side of the cover plate 10 facing the second swing plate 9. Figure 5 As shown), the extrusion section 8 works in conjunction with the second swing plate 9. A locking nut 17 is fixedly fitted onto the end of the guide post 18 furthest from the impact-resistant steel plate 2. A tension spring 16 is wound around the guide post 18, with its two ends fixed to the end face of the locking nut 17 and the surface of the cover plate 10, respectively. When the water flow is small or the waves are small, the impact force of the water flow on the second swing plate 9 is small, resulting in a small swing amplitude of the second swing plate 9. Consequently, the extrusion section 8 experiences less extrusion from the second swing plate 9, thus reducing the range of motion of the cover plate 10. When the water flow is large... Or, if the waves are large, the water flow has a greater impact on the second swing plate 9, causing the second swing plate 9 to swing more. The second swing plate 9 will squeeze the squeezing part 8, and the squeezing part 8 will drive the cover plate 10 to move towards the impact-resistant steel plate 2, so that the cover plate 10 is in contact with the surface of the impact-resistant steel plate 2, thereby blocking and sealing the connecting port 15, so that the water flow will not interfere with the flow of water in the buffer chamber 3. That is, at this time, the water in the buffer chamber 3 can quickly stop and can provide auxiliary buffering for the movement of the impact-resistant steel plate 2.

[0021] Working principle of the invention: When the water flow or waves are small, the impact of the water flow on the second swing plate 9 is small, so that the cover plate 10 will not cover the connecting opening 15, allowing water in the riverbank water to enter the buffer chamber 3. At this time, the impact-resistant steel plate 2 mainly provides impact protection against the water flow and waves. The stepped structure formed by the flip plate 4 and the baffle 6 can cut and disperse the water flow, so that the impact force of the water flow on the impact-resistant steel plate 2 can be weakened. The water flow or waves are blocked by the baffle 6 and will not flow into the top of the dam 1 along the surface of the impact-resistant steel plate 2, thereby causing soil erosion and damage to the top of the dam 1. At this time, since the water inside and outside the buffer chamber 3 is in a flowing state, when the impact-resistant steel plate 2 is impacted by the water flow and waves, the water pressure inside and outside the buffer chamber 3 is the same, so the fixed beam 13 can compress the spring 21 to a large extent, thereby enabling the impact-resistant steel plate 2 to buffer and protect against the impact of the water flow and waves. When the water flow or waves are large, the water flow will generate a large impact force on the second swing plate 9, causing the second swing plate 9 to drive the first swing plate 11 to swing along the hinge point with the lower side of the impact-resistant steel plate 2. This causes the second swing plate 9 to swing towards the impact-resistant steel plate 2, and the second swing plate 9 will exert pressure on the extrusion part 8, causing the cover plate 10 attached to the extrusion part 8 to move towards the impact-resistant steel plate 2 and adhere to its surface. Simultaneously, the tension spring 16 is fixed to the cover plate 10, so it will be stretched under the tension of the cover plate 10 and accumulate elastic potential energy. After the cover plate 10 adheres to the surface of the impact-resistant steel plate 2, it further… The opening of the connecting port 15 is covered, which creates a pressure difference between the water inside and outside the buffer chamber 3. Specifically, the water pressure outside the buffer chamber 3 (i.e., the river water) is greater than the water pressure inside the buffer chamber 3. Since the space of the buffer chamber 3 is small, the water inside the buffer chamber 3 will not flow. When the impact-resistant steel plate 2 is impacted by a large water flow, the impact-resistant steel plate 2 will be subjected to the elastic resisting force of the spring 21 on the fixed beam 13 and the resistance of the water inside the buffer chamber 3 against the impact-resistant steel plate 2. Under the action of these two forces, the impact of the water flow on the impact-resistant steel plate 2 can be buffered. Furthermore, when the second swing plate 9 swings towards the impact-resistant steel plate 2, it causes the connecting rod 7 to cause one of the lower flip plates 4 to flip upwards. The two flip plates 4 are hinged together by a hinge rod 5. Therefore, when one flip plate 4 flips, it will simultaneously cause the other flip plate 4 to flip upwards, making both flip plates 4 flip upwards simultaneously. This also causes the baffle 6 to flip upwards. In this way, when the water flow and waves impact the surface of the impact-resistant steel plate 2, the waves on the water surface will flow down the surface of the impact-resistant steel plate 2 and into the upper flip plate. Between plate 4, baffle 6, and arc section 14, and guided by arc section 14, the water flow is allowed to fall back into the river water. Meanwhile, the waves below the water surface will flow down the surface of the impact-resistant steel plate 2 into the space between the flip plate 4, baffle 6, and arc section 14 located below, and guided by arc section 14, the water flow is allowed to fall back into the river water. In this way, the two flip plates 4, baffle 6, and arc section 14 can buffer the water flow and waves in the river water, avoiding impact on the dam 1 and the soil layer on the top surface of the dam 1. When the water flow reverses, the second swing plate 9 will swing in the opposite direction with the water flow, and at the same time, it will be pulled by the tension spring 16 on the cover plate 10. The cover plate 10 will move away from the impact-resistant steel plate 2. At the same time, the cover plate 10 will drive the extrusion part 8 to move, and the extrusion part 8 will also generate a thrust on the second swing plate 9, causing the second swing plate 9 to move away from the impact-resistant steel plate 2. The cover plate 10 will move away from the impact-resistant steel plate 2, so that the connecting port 15 will be in an open state.
