Description

Technical Field

[0001] The utility model relates to the technical field of water pollution repair, in particular to a reservoir dam repair system that is adaptive to water level changes. Background Art

[0002] The adaptive water level change reservoir dam repair system protects the dam from water scouring and erosion through upstream and downstream gabion cage mesh footing, extending the service life of the dam. The system design can adapt to changes in reservoir water level and maintain the effectiveness of its functions regardless of whether the water level rises or falls. Through the dam top ecological mat and plant coverage, as well as the formation of biofilm, it promotes the recovery and maintenance of the aquatic ecosystem, provides a habitat for aquatic organisms, and optimizes the operation and management of the reservoir. The ecological design and plant coverage in the system not only improve the ecological function of the reservoir, but also enhance its landscape value. The adaptive water level change reservoir dam repair system is a multifunctional water conservancy and ecological project aimed at comprehensively protecting the reservoir environment, improving water quality, maintaining dam safety, and promoting ecological balance.

[0003] The Chinese patent authorization announcement number is CN212223793U, and the name is a composite hollow structure ecological permeable dam. The dam foundation of this utility model adopts a horse stool leg structure, and the leg length on the water-facing side is longer than the leg length on the back-water side, which effectively resists the impact of water flow and stabilizes the dam body. A central control structure is set in the middle of the dam body, and an ecological interception box is set inside the hollow structure to form a multi-stage treatment of the water body, effectively purifying the water quality and improving the ecological environment. A lifting structure is set at the upper end of the ecological interception box. The ecological interception box is lifted by a hook, and the telescopic rod is raised and placed. The track drives the telescopic rod to move the ecological interception box, making it easy to place and remove the ecological interception box at any time.

[0004] The shortcomings of the above solution are: although the above solution can facilitate the placement and removal of the ecological interception box at any time, it cannot effectively intercept all types of pollutants when in use, especially those tiny or soluble pollutants. Over time, the materials in the system may age or be damaged, such as the corrosion of gabion stone cages and the wear of ecological mats. It may not be able to fully adapt to extreme water level changes. When the water level rises or falls rapidly, it may cause technical problems such as pollutants bypassing the interception facilities. Utility Model Content

The dam top ecological mat is located between the upstream gabion mesh foot guard and the downstream gabion mesh foot guard. It can adapt to changes in water levels. The ecological mat is made of permeable material, allowing water to pass through while providing an eco-friendly surface. The gabion mesh foot guard is composed of metal mesh and filled with stones to form a solid structure that can withstand the force of water flow and prevent the dam body from being eroded by water scouring. Due to the solidity of the gabion mesh, they can reduce the need for regular maintenance of the dam body, thereby reducing long-term maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Working principle of the utility model: This reservoir dam body repair system that adapts to water level changes is complex in design and is intended to work together through multiple components to adapt to water level changes while repairing and protecting the dam body. The upstream gabion gabion mesh foot guard 3 and the downstream gabion gabion mesh foot guard 4 are used to protect the dam body from water scour and erosion. The gabion gabion is composed of metal mesh and filled with stones to form a solid structure. The dam top ecological mat 5 is located between the upstream gabion gabion mesh foot guard 3 and the downstream gabion gabion mesh foot guard 4, which is able to adapt to changes in water levels. The ecological mat is made of permeable material, allowing water to pass through while providing an eco-friendly surface. The ecological interception box 1 is located on the dam top ecological mat 5 to intercept and collect pollutants. The bottom ecological mat 2 is connected to the bottom of the ecological interception box 1, which helps In order to further filter pollutants, the gravel layer 13 is located on the far side of the ecological interception box 1, which is used for preliminary filtering and precipitation of larger particles. The sedimentation area 12 is located after the gravel layer 13, which is used for further precipitation of smaller particles. The biofilm 11 is located after the sedimentation area 12 and is composed of microorganisms that can decompose organic pollutants. The filter layer 9 is located between the gravel layer 13, the sedimentation area 12 and the biofilm 11 to prevent soil and fine particles from passing through. The slope surface ecological mat 10 covers the filter layer 9 to provide additional ecological protection and beautification effects. The interception mechanism includes a slope protection net 6, which is connected to the dam top ecological mat 5 to intercept floating objects and pollutants. The locking mechanism consists of a connecting rod 7 and a plug-in screw 8 to ensure that the slope protection net 6 is firmly connected to the dam top ecological mat 5.

[0029] When the water level rises, the water flows through the dam top ecological mat 5. Pollutants are first intercepted by the ecological interception box 1. As the water flows through the gravel layer 13, larger particles are deposited in the sedimentation area 12. Fine particles and organic pollutants are decomposed by the biofilm 11. The filter layer 9 prevents soil and fine particles from entering the biofilm 11. The slope protection net 6 in the interception mechanism further intercepts floating objects, and the locking mechanism ensures its stability.

[0030] Through the synergistic effect of these components, it can effectively adapt to water level changes, while achieving the repair and protection of the reservoir dam and the purification of water quality.
