Description

Technical Field

[0001] This utility model relates to the field of flood control and slope protection technology, specifically a flood control and slope protection method for water conservancy projects. Background Technology

[0002] Traditional flood control slope protection in water conservancy projects mostly uses fixed structures, such as concrete slope protection and masonry slope protection, whose protection height is not adjustable. During the flood season, when water levels rise, such slope protection may be insufficient in height, leading to flooding and causing dike breaches or inundation of surrounding areas. Some adjustable slope protection solutions suffer from poor structural stability, cumbersome operation, or reliance on large machinery, making them difficult to respond quickly in emergency situations.

[0003] For example, Chinese Patent Publication No. CN220767906U describes a flood control slope protection system for a water conservancy project, comprising a slope body and a slope surface. Multiple water-retaining plates are fixedly connected to the slope surface. These plates are parallel to each other and evenly distributed along the height direction of the slope surface. The water-retaining plates are perpendicular to the slope surface, and a blocking plate is hinged to the top of the slope surface. By using the blocking plates, the protective height of the slope surface is increased, thereby reducing the risk of river water surging onto the riverbank.

[0004] However, in actual use, the baffle plate relies on expansion bolts for fixation, and the fulcrum is prone to breakage under the impact of water flow, leading to the failure of the overall structure.

[0005] Therefore, this application provides a flood control slope protection method for water conservancy projects, which solves the problems of the non-adjustable protection height and poor protection effect of existing flood control slope protection methods. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a flood control slope protection system for water conservancy projects.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a flood control slope protection for water conservancy projects, including a flood control slope protection body, on which slope protection bricks and several guide beams are evenly laid, and the length direction of the guide beams is set along the inclination direction of the slope.

[0008] The main body of the flood control slope is equipped with a support part at the top of the slope, and an extension slope is slidably provided on the upper part of two adjacent guide beams. The movable end of the support part is rotatably connected to the upper end of the extension slope. When the extension slope is extended, it pulls the extension slope upward along the guide beam, thereby increasing the protection height of the main body of the flood control slope.

[0009] As an optimization, the upper end of the guide beam is not lower than the top of the flood control slope protection body, and the lower end of the guide beam extends to the lower part of the flood control slope protection body.

[0010] As an optimization, guide grooves are provided on two opposite sides of the guide beam, and the two ends of the extension slope are engaged between the guide grooves of two adjacent guide beams.

[0011] As an optimization, auxiliary plates are connected to both ends of the extended slope along its length. The auxiliary plates are arranged in a Y-shape with the extended slope, and the outer ends of the auxiliary plates are parallel to the extended slope and located outside the guide beam.

[0012] As an optimization, the upper part of the slope surface of the main flood control slope protection body is a hard slope surface, and the extended slope is set parallel to and attached to the hard slope surface.

[0013] As an optimization, the support part includes several adjustable telescopic rods and several driving telescopic rods. The top of the flood control slope protection body is provided with a connecting groove, and the lower end of the driving telescopic rod is rotatably connected to the inside of the connecting groove.

[0014] The top of the flood control slope protection body is set on a fixed base. One end of the adjustable telescopic rod is rotatably connected to the fixed base, and the other end of the adjustable telescopic rod is rotatably connected to the top of the extended slope. A connecting beam is provided between several of the adjustable telescopic rods, and the extended end of the driving telescopic rod is rotatably connected to the connecting beam.

[0015] As an optimization, the connecting beam is positioned adjacent to the top of the extended slope.

[0016] As an optimization, the lower end of the drive telescopic rod is located between the upper part of the connecting seat and the extension slope, the front side of the connecting groove is an inclined surface, and the rear side of the connecting groove is a vertical surface.

[0017] The extended slope includes an initial state and an extended state. In the initial state, the driving telescopic rod is arranged along the front side of the connecting groove. In the extended state, the driving telescopic rod is arranged along the rear side of the connecting groove, and the adjusting telescopic rod forms a triangular support structure with the extended slope and the top of the slope.

[0018] As an optimization, the adjusting telescopic rod is a spring rod, and the driving telescopic rod is an electric telescopic rod;

[0019] In the initial state, the adjusting telescopic rod is in a fully extended state, and the driving telescopic rod is in a retracted state;

[0020] In the extended state, the adjusting telescopic rod is in the fully retracted state, and the driving telescopic rod is in the extended state.

[0021] As an optimization, a protective plate is rotatably connected to the top of the connecting groove, and the end of the protective plate away from the extension slope is rotatably connected to the connecting groove. The protective plate can only be rotated upwards.

[0022] The beneficial effects of this plan are as follows:

[0023] By sliding the guide beam with the extended slope, the stability of the extended slope connection is effectively improved. Combined with the telescopic drive of the support part, the slope protection height can be quickly raised to effectively cope with rising water levels and avoid the risk of flooding.

[0024] The extended slope guide beam slides in a directional manner, and the auxiliary plate and Y-shaped design enhance the overall erosion resistance; the triangular support structure formed by the adjusting telescopic rod and the driving telescopic rod provides stable mechanical support in the extended state.

[0032] like Figures 1-6 As shown, a flood control slope protection for a water conservancy project includes a flood control slope protection body 1. Slope protection bricks 2 and several guide beams 3 are evenly laid on the slope surface of the flood control slope protection body 1. The length direction of the guide beams 3 is set along the inclination direction of the slope surface.

[0033] The top of the flood control slope protection body 1 is equipped with a support part, and an extension slope 4 is slidably provided on the upper part of two adjacent guide beams 3. The movable end of the support part is rotatably connected to the upper end of the extension slope 4. When the extension slope 4 is extended, it pulls the extension slope 4 upward along the guide beam 3, thereby increasing the protection height of the flood control slope protection body 1.

[0034] The main body of the flood control slope protection structure 1 features a hard slope design, with slope protection bricks 2 laid on the surface to enhance erosion resistance. These bricks are fixed in place by embedded splicing to prevent displacement due to water flow impact. Guide beams 3 are evenly distributed along the slope's inclination direction, extending to the lower part of the slope protection to anchor to the foundation, while their upper ends are flush with or slightly higher than the slope top, forming a continuous support framework. Guide grooves are provided on both sides of the guide beams 3 to provide precise limiting for the sliding of the extended slope 4, preventing lateral displacement. The hard slope surface and the extended slope 4 are initially parallel and closely fitted, ensuring continuous protection and reducing the risk of water seepage. The combination of slope protection bricks 2 and guide beams 3 ensures both basic protection strength and provides structural support for dynamic adjustment.

[0035] like Figure 1 As shown, the upper end of the guide beam 3 is not lower than the top of the flood control slope protection body 1, and the lower end of the guide beam 3 extends to the lower part of the flood control slope protection body 1.

[0036] like Figure 2 As shown, guide grooves are provided on two opposite sides of the guide beam 3, and the two ends of the extension slope 4 are engaged between the guide grooves of two adjacent guide beams 3.

[0037] like Figure 2 As shown, auxiliary plates 5 are connected to both ends of the extended slope 4 along its length. The auxiliary plates 5 are arranged in a Y-shape with the extended slope 4. The outer ends of the auxiliary plates 5 are parallel to the extended slope 4 and are located on the outside of the guide beam 3.

[0038] The extension slope 4 achieves a sliding connection by embedding guide grooves into adjacent guide beams 3 at both ends, and its outer side is expanded by a Y-shaped auxiliary plate 5 to increase the stress-bearing area. The outer end of the auxiliary plate 5 is parallel to the extension slope 4 and extends to the outer side of the guide beams 3, forming a diversion structure that can disperse the impact force of water flow and reduce local stress concentration. The extension slope 4 is made of lightweight and high-strength materials (such as aluminum alloy or composite materials) to reduce the lifting load, and the surface can be equipped with anti-slip textures or ecological planting holes to meet both erosion resistance and ecological restoration needs.

[0039] The angle between the Y-shaped auxiliary plate 5 and the extended slope 4 is typically 120°, which optimizes water flow guidance and prevents eddy current erosion of the slope. Wear-resistant coatings or ball bearings are installed at the sliding joints to reduce frictional resistance and extend service life.

[0040] like Figure 5 As shown, the upper part of the slope surface of the flood control slope protection body 1 is a hard slope surface, and the extended slope 4 is set parallel to and attached to the hard slope surface.

[0041] like Figure 5 and Figure 6As shown, the support part includes several adjustable telescopic rods 6 and several driving telescopic rods 7. The top of the flood control slope protection body 1 is provided with a connecting groove 9, and the lower end of the driving telescopic rod 7 is rotatably connected to the inside of the connecting groove 9.

[0042] The top of the flood control slope protection body 1 is set on a fixed base. One end of the adjustable telescopic rod 6 is rotatably connected to the fixed base, and the other end of the adjustable telescopic rod 6 is rotatably connected to the top of the extended slope 4. A connecting beam 8 is provided between several of the adjustable telescopic rods 6, and the extended end of the driving telescopic rod 7 is rotatably connected to the connecting beam 8.

[0043] The connecting beam 8 is disposed adjacent to the top of the extended slope 4.

[0044] The lower end of the drive telescopic rod 7 is located between the upper part of the connecting seat and the extension slope 4. The front side of the connecting groove 9 is an inclined surface, and the rear side of the connecting groove 9 is a vertical surface.

[0045] The extension slope 4 includes an initial state and an extended state. In the initial state, the driving telescopic rod 7 is arranged along the front side of the connecting groove 9. In the extended state, the driving telescopic rod 7 is arranged along the rear side of the connecting groove 9, and the adjusting telescopic rod 6 forms a triangular support structure with the extension slope 4 and the top of the slope.

[0046] In the initial state, the drive telescopic rod 7 is folded into the inclined surface to reduce space occupation; the rear side is a vertical surface, and in the extended state, the drive telescopic rod 7 abuts against the vertical surface to form rigid support.

[0047] The adjusting telescopic rod 6 is a spring rod, and the driving telescopic rod 7 is an electric telescopic rod;

[0048] In the initial state, the adjusting telescopic rod 6 is in a fully extended state, and the driving telescopic rod 7 is in a retracted state;

[0049] In the extended state, the adjusting telescopic rod 6 is in a fully retracted state, and the driving telescopic rod 7 is in an extended state.

[0050] The electric telescopic pole 7 uses a waterproof motor and worm gear drive, which has high torque and self-locking function to ensure that it will not fall back under the impact of water level.

[0051] The triangular support structure (adjustable telescopic rod 6, extended slope 4, and slope top) forms a stable mechanical triangle in the extended state, and its anti-overturning ability is significantly better than that of the traditional baffle hinge design.

[0052] like Figure 3 and Figure 5As shown, a protective plate 10 is rotatably connected to the top of the connecting groove 9. The end of the protective plate 10 away from the extension slope 4 is rotatably connected to the connecting groove 9. The protective plate 10 can only be rotated upwards.

[0053] When using the device, first, the extension slope 4 is set to fit against the hard slope surface, the telescopic rod 6 is adjusted to be in a fully stretched state, the telescopic rod 7 is driven to retract into the connecting groove 9, and the protective plate 10 is in a closed state.

[0054] When the water level rises rapidly, the electric telescopic rod 7 is activated, which extends and pushes the connecting beam 8 upward, causing the adjusting telescopic rod 6 to retract, and pulling the extension slope 4 to rise along the guide beam 3 to the target height. During this process, the protective plate 10 opens as the driving telescopic rod 7 rotates. The protective plate 10 can also be set to an automatic opening and closing structure.

[0055] In the extended state, the drive telescopic rod 7 abuts against the vertical surface of the connecting groove 9, and the telescopic rod 6 is adjusted to retract to its shortest state, forming a triangular support with the extended slope 4 and the top of the slope to resist the impact of water flow.

[0056] After the water level drops, the electric telescopic rod 7 retracts, the adjustable telescopic rod 6 elastically resets, the extension slope 4 slides down the guide groove to the initial position, and the protective plate 10 closes.

[0057] The above-described specific embodiments are merely specific examples of this utility model. The patent protection scope of this utility model includes, but is not limited to, the product form and style of the above-described specific embodiments. Any appropriate changes or modifications made by a person skilled in the art to a flood control slope protection system for a water conservancy project that conforms to the claims of this utility model should fall within the patent protection scope of this utility model.
