Description

Technical Field

[0001] The present invention relates to the technical field of ecological slope protection, and in particular to a river ecological management slope protection for water conservancy projects. Background Art

[0002] As infrastructure for controlling and regulating natural surface and groundwater, water conservancy projects achieve the goals of flood control, irrigation, water supply, and power generation through the construction of dams, channels, sluices, and other engineering facilities. River bank protection is a key component of water conservancy project construction, maintaining river channel stability and protecting the surrounding ecological environment. Ecological slope protection technology, through scientific support of river channel slopes or side slopes, not only stabilizes the bank structure but also promotes the restoration and balance of the ecosystem. It is an important means of achieving the coordinated development of water conservancy project construction and ecological and environmental protection.

[0003] Currently, existing river channel ecological slope protection often uses water retaining grids to buffer water flow and intercept garbage. These grids are typically constructed of materials such as brick, stone, and concrete, forming a regular grid structure. As water flows through, the grids reduce the impact of the current and its velocity, while also trapping floating garbage and debris within the grids. This, to a certain extent, alleviates the pressure on river channel garbage removal and reduces the risk of downstream blockage.

[0004] This traditional water-retaining grid slope protection has obvious defects. The garbage intercepted in the grid is exposed above the water surface. When the water level drops and the water flow recedes, the garbage can easily break away from the grid and re-enter the river water due to the influence of wind and residual impact force of the water flow. This not only makes the previous garbage interception work ineffective, but also causes secondary pollution of the river environment. In addition, the garbage intercepted by the grid on the slope protection can easily clog the drainage outlet of the slope protection, affecting the drainage effect of the slope protection. Summary of the Invention

[0005] In view of the above problems in the prior art, the present invention is proposed.

[0006] Therefore, the purpose of the present invention is to provide a river ecological management slope protection for water conservancy projects. The problem to be solved is that the garbage intercepted by the traditional water-retaining grid slope protection is exposed to the water surface. After the water level drops, it is easy to return to the river channel under the action of wind and residual impact force of water flow, resulting in interception failure and causing secondary pollution; and the garbage intercepted by the grid on the slope protection is easy to block the drainage outlet of the slope protection, affecting the drainage effect of the slope protection.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] The embodiment of the present invention discloses a river ecological management slope protection for water conservancy projects.

[0033] Example 1

[0034] Reference Figure 1-7The first embodiment of the present invention provides a river channel ecological management slope protection for water conservancy projects. The river channel ecological management slope protection for water conservancy projects includes a slope protection body 1. A flow disturbance step 101 is provided on the side of the slope protection body 1 close to the river channel. A drainage channel 102 for drainage is also provided in the slope protection body 1. An ecological dam 2 is provided on the side of the slope protection body 1 away from the drainage channel 102. The flow disturbance step 101 is provided with linearly arranged interception holes. A water collection cylinder 3 corresponding to the interception holes is fixedly installed in the slope protection body 1. A drainage cylinder 4 is fixedly installed at the bottom end of the water collecting cylinder 3, and a dust cover 5 driven by a buoyancy device is also provided in the water collecting cylinder 3. A garbage collecting cylinder 6 for collecting garbage is also installed in the water collecting cylinder 3 and between the dust cover 5 and the drainage cylinder 4. A drainage cavity 401 is provided in the drainage cylinder 4, and a drainage port 402 connected to the drainage cavity 401 is provided at the bottom end of the drainage cavity 401, and the drainage cavity 401 is connected to the drainage channel 102 through the drainage port 402. The slope protection body 1 serves as the foundation of the entire ecological management slope protection. The structure is cast with high-strength concrete and steel skeleton. The unique stepped design of the flow-disrupting ladder 101 can effectively weaken the impact of water flow, reduce the water flow speed, and reduce the erosion of water flow on the slope protection body 1. The interception holes are linearly arranged in the flow-disrupting ladder 101. When the water flows through, part of the garbage and sediment carried by the water flow will enter the water collection tube 3 through the interception holes with the water flow, achieving preliminary interception. The drainage channel 102 runs through the slope protection body 1, providing a channel for the water discharged from the water collection tube 3 to ensure smooth discharge of water. , to avoid accumulation in the slope protection body 1, the ecological dam 2 is located in the construction of the ecological environment, and cooperates with the slope protection body 1 to ensure the stability of the river bank. The water collection cylinder 3, the drainage cylinder 4, the dust cover 5 and the garbage collection cylinder 6 together constitute a garbage collection and drainage system. The water collection cylinder 3 receives the water and garbage flowing in from the interception hole, and the drainage cylinder 4 is responsible for discharging the water in the water collection cylinder 3 to the drainage channel 102. The dust cover 5 controls the opening and closing size of the water collection cylinder 3 under the drive of the buoyancy device, and the garbage collection cylinder 6 is used to store the intercepted garbage.

[0035] The inner wall of the water collecting cylinder 3 is also fixedly installed with a retaining ring body 8 that is interference fit with the dust cover 5, and the inner wall of the retaining ring body 8 is fixedly installed with a stopper 801 for supporting the dust cover 5, and the stopper 801 is located below the dust cover 5. The retaining ring body 8 can make up for the gap between the water collecting cylinder 3 and the dust cover 5, and ensure that the dust cover 5 has good sealing performance in the closed state through interference fit, preventing garbage and odor from leaking out, and at the same time, it can also effectively block water from overflowing from the opening of the water collecting cylinder 3. The stopper 801 can provide a support point for the dust cover 5. When the dust cover 5 is closed, the stopper 801 can withstand the gravity of the dust cover 5 and the pressure of the water flow on the dust cover 5, thereby enhancing the stability of the dust cover 5 when it is closed, and when the dust cover 5 is in the closed state, water can still leak through the gap between the dust cover 5 and the retaining ring body 8.

[0036] A limiting bracket 7 is installed between the drainage tube 4 and the garbage collection tube 6. The limiting bracket 7 is fixedly installed on the inner wall of the water collection tube 3, and the garbage collection tube 6 is fixedly installed in the water collection tube 3 through the limiting bracket 7. A vertically distributed column 701 is also provided at the center of the limiting bracket 7. The limiting bracket 7 can enhance the structural strength of the hollow tubular water collection tube 3 and provide its pressure resistance. The garbage collection tube 6 is precisely positioned in the water collection tube 3 through the limiting bracket 7, which is convenient for collecting garbage entering the water collection tube 3 from the interception hole.

[0037] The buoyancy device includes a drainage piston 9 located below the garbage collection barrel 6, and a first L-shaped top rod 901 and a second L-shaped top rod 902 are fixedly installed on the drainage piston 9, and the vertically upward ends of the first top rod 901 and the second top rod 902 pass through the garbage collection barrel 6 and are located below the dust cover 5. A buoyancy seat 10 is provided between the first top rod 901 and the second top rod 902 and on the outer sleeve of the drainage piston 9. The drainage piston 9 can cooperate with the drainage barrel 4 to realize the drainage function. When the water level in the water collection barrel 3 rises, the water flow pushes the drainage piston 9 to move upward, which is installed The first push rod 901 and the second push rod 902 on the drainage piston 9 rise accordingly. Since the first push rod 901 and the second push rod 902 are located under the dust cover 5 after passing through the garbage collection barrel 6, the rising push rods will lift the dust cover 5, so that the water collection barrel 3 is opened to facilitate the entry of water and garbage. The buoyancy seat 10 can provide additional buoyancy during the rising process of the drainage piston 9, assisting the drainage piston 9 to rise more smoothly. At the same time, when the water level drops, the gravity of the buoyancy seat 10 can help the drainage piston 9 reset faster, ensuring that the dust cover 5 is closed in time to prevent garbage from overflowing.

[0038] The drainage piston 9 is also provided with a ring-shaped array of filter grooves 903. The end of the drainage piston 9 extending into the drainage cylinder 4 is also provided with a plug 11 that fits with the clearance of the drainage cylinder 4. The end of the plug 11 away from the drainage piston 9 is located in the drainage cavity 401. The filter groove 903 allows the filtered water in the water collection cylinder 3 to pass through, so that the drainage function of the device always remains unobstructed, avoiding a large amount of water accumulation in the water collection cylinder 3. When the drainage piston 9 descends, the plug 11 gradually blocks the drainage cavity 401, preventing the water from continuing to be discharged, so that the water level in the water collection cylinder 3 remains stable, and at the same time prevents garbage from entering the drainage channel 102. This design realizes the switching of the drainage piston 9 between emergency drainage and normal drainage functions, thereby adapting to different river conditions.

[0039] The top of the dust cover 5 is provided with a diversion slope 501, and the dust cover 5 is also provided with a ring array of water filtering holes 502. The bottom of the dust cover 5 is provided with a hinge part 503, and the hinge part 503 is hingedly connected to a positioning rod 504, and the top of the positioning rod 504 is hingedly connected to the dust cover 5 through the hinge part 503. The bottom end of the positioning rod 504 extends into the column 701. The design of the diversion slope 501 can guide the water to flow smoothly from the surface of the dust cover 5 to avoid water flowing on the top of the dust cover 5. The dust cover 5 is provided with a ring array of water filtering holes 502. When the dust cover 5 is closed, the water in the water collecting cylinder 3 is allowed to pass through, and the water flow in the water collecting cylinder 3 is kept unobstructed. The hinged design of the hinge part 503 and the positioning rod 504 enables the dust cover 5 to rotate around the hinge point as the center, and realizes the opening and closing action under the drive of the buoyancy device. The positioning rod 504 can slide in the column 701, so that the dust cover 5 always moves in the vertical direction.

[0040] The top of the dust cover 5 is also provided with a hoisting part 505 for hoisting, and the outside of the dust cover 5 is sprayed with an anti-corrosion coating. The hoisting part 505 is arranged on the top of the dust cover 5, which is convenient for the staff to lift the dust cover 5 through the hoisting equipment when maintaining and cleaning the garbage collection bin 6, so that the positioning rod 504 is separated from the column 701, which is convenient for taking out the garbage in the garbage collection bin 6.

[0041] The ecological dam 2 is also provided with planting troughs 201 for transplanting ecological plants, and the planting troughs 201 are evenly distributed along the arrangement trajectory of the water collection tube 3. The planting troughs 201 on the ecological dam 2 provide space for transplanting ecological plants such as aquatic plants and herbaceous plants, and the design of evenly distributed along the arrangement trajectory of the water collection tube 3 enables the ecological plants to form a continuous ecological belt, and together with the artificial slope protection body 1, realize the harmonious coexistence of water conservancy projects and the ecological environment.

[0042] During use, when the river water hits the slope protection body 1, the flow-disturbing ladder 101 close to the river side takes effect first. Its stepped structure effectively weakens the impact force of the water flow, reduces the water flow speed, and reduces the erosion of the slope protection body 1 by changing the direction of the water flow and increasing the length of the water flow path. The planting troughs 201 evenly distributed along the trajectory of the water collecting tube 3 on the ecological dam 2 provide space for transplanting ecological plants such as aquatic plants and herbaceous plants, forming a continuous ecological belt. The interception holes linearly arranged in the flow-disturbing ladder 101 intercept the water flow carrying garbage and sediment. These water flows and impurities flow into the slope protection body 1 and enter the water collecting tube 3 corresponding to the interception hole through the dust cover 5 lifted by the buoyancy device. The garbage is intercepted in the garbage collection tube 6, thereby effectively avoiding the probability of garbage entering the river again compared with the traditional direction.

[0043] After the water collecting cylinder 3 receives the water flow and garbage, the internal water level gradually rises. At this time, the drainage piston 9 located below the garbage collecting cylinder 6 moves upward under the action of buoyancy, and the first push rod 901 and the second push rod 902 installed on the drainage piston 9 rise accordingly. Since the two push rods are located below the dust cover 5 after passing through the garbage collecting cylinder 6, the dust cover 5 will be lifted up during the rising process, causing it to rotate around the hinge 503, opening the water collecting cylinder 3 to facilitate the subsequent water flow and garbage to enter. At the same time, the buoyancy seat 10 sleeved on the outside of the drainage piston 9 provides additional buoyancy to assist the drainage piston 9 to rise more smoothly. As the water flow continues to enter, the dust cover 5 remains open under the drive of the buoyancy device, and continues to collect garbage, thereby avoiding garbage accumulation outside and ensuring the stability of the slope protection and drainage function;

[0044] The filter groove 903 on the drain piston 9 allows the water in the water collection cylinder 3 that has been preliminarily filtered to pass through and enter the drainage chamber 401 of the drain cylinder 4, and then be discharged into the drainage channel 102 through the drain port 402, thus realizing the drainage function; the drain piston 9 extends to the plug 11 in the drain cylinder 4 and is clearance-matched with the drain cylinder 4. When the drain piston 9 rises, the plug 11 opens the drainage chamber 401, ensuring smooth drainage; when the water flow in the water collection cylinder 3 slows down, the drain piston 9 resets under the action of gravity of the buoyancy seat 10, and the plug 11 gradually blocks the drainage chamber 401, so that the water in the water collection cylinder 3 can only be slowly discharged into the drainage chamber 401 through the filter groove 903;

[0045] When the water level in the water collecting cylinder 3 drops, the drainage piston 9 returns to its original position and the dust cover 5 is also closed. At this time, the interference fit between the retaining ring body 8 and the dust cover 5 and the support of the block 801 ensure that the dust cover 5 is well sealed, preventing garbage from overflowing and odor from emitting. In the closed state, water can still leak through the gap between the dust cover 5 and the retaining ring body 8 and the water filter hole 502.

[0046] When it is necessary to clean the garbage in the garbage collecting bin 6, the staff uses the lifting equipment through the lifting part 505 to lift the dust cover 5, separate the positioning rod 504 from the column 701, and after removing the dust cover 5, the garbage collecting bin 6 can be taken out for cleaning, and then reinstalled after cleaning.
