[0002] This utility model relates to the field of river ecological protection technology, specifically to an ecological protection structure for river drawdown zones. Background Technology

[0003] The drawdown zone refers to the water-land transition area in rivers, lakes, and reservoirs, where the surrounding land is periodically submerged and exposed between the highest and lowest water levels due to human intervention or natural seasonal fluctuations in water levels. It falls under the category of wetlands. The drawdown zone is a water-land transition zone; in its natural state, vegetation is sparse, biodiversity is low, and the ecological community is easily damaged.

[0004] Application No. (CN 219930861 U) discloses an ecological protection structure for a river drawdown zone, belonging to the field of river ecological protection. It includes a riverbed and a riverbank. The top of the riverbed is provided with a layer of pebbles. One side of the riverbank is provided with three slopes. The three slopes are laid with a first-level concrete slope, a second-level concrete slope and a third-level concrete slope in order from low to high. A fixing frame is provided at the two boundaries of the three slopes. A buffer plate is fixedly connected inside the fixing frame. A first connector and a second connector are fixedly connected to both sides of the fixing frame, respectively.

[0005] The design uses a wall to block the waves, but this method requires a lot of resources. It requires first forming staggered concrete riverbanks and then erecting the wall on the riverbanks. This consumes a lot of resources, takes a long time, and is difficult to construct. In addition, this method of blocking the waves is not aesthetically pleasing and makes it difficult to showcase the natural vegetation along the river. Therefore, we propose an ecological protection structure for the river drawdown zone to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides an embodiment of an ecological protection structure for a river drawdown zone, including a water flow baffle 1, a fixed plate 2 fixedly installed on the lower side of the water flow baffle 1, fixed spikes 3 movably inserted in an array on the water flow baffle 1, a guide channel 4 installed on one side of the water flow baffle 1, the upper end of the guide channel 4 being flush with the lower side of the water flow baffle 1, and a protective net 5 movably installed on the water flow baffle 1. This device uses the water flow baffle 1, which can block the rapid descent of water flow, to reduce the amount of soil carried away by the water flow. In addition, the protective net 5 is also provided to fix the soil, increasing the efficiency of soil solidification during the use of the device.

[0023] Furthermore, the lower side of the water flow baffle 1 is arranged with three sets of insertion fixing plates 2, and the upper end of the three sets of insertion fixing plates 2 is provided with fixing blocks 6. The three sets of insertion fixing plates 2 are connected by the same fixing block 6. The fixing block 6 and the lower end of the insertion fixing plate 2 are sharp, and the surface of the insertion fixing plate 2 is rough. This structure allows the insertion fixing plate 2 to be stably inserted into the soil and increases the friction between the insertion fixing plate 2 and the soil, thereby increasing the stability of the water flow baffle 1 during installation. The fixing block 6 can increase the stability of the connection between the insertion fixing plates 2, and the sharp lower side can make the insertion fixing plate 2 and the fixing block 6 better inserted into the soil.

[0024] Furthermore, the water flow baffle 1 has three sets of fixing grooves 7, and the fixing spikes 3 are inserted into the fixing grooves 7. The diameter of the upper end of the fixing spikes 3 is larger than the diameter of the fixing grooves 7. A guide plate 8 is fixedly installed on the front side of the water flow baffle 1. The center of the guide plate 8 protrudes. This structure allows the fixing spikes 3 to be inserted into the fixing grooves 7 and then penetrate into the soil to fix the water flow baffle 1, increasing the stability of the equipment during use. In addition, the guide plate 8 allows the water flow to flow to the left and right sides of the water flow baffle 1, increasing the functionality of the equipment during use.

[0025] Furthermore, a limiting block 9 is fixedly installed at the upper end of the fixed spike 3. The size of the limiting block 9 is larger than that of the fixed block 6. The center of the limiting block 9 is narrower than the two ends. The material of the limiting block 9 is the same as that of the fixed spike 3. This structure allows the fixed spike 3 to stably fix the water flow baffle 1, while the limiting block 9 allows the fixed spike 3 to be easily pulled out after it has penetrated the mud, increasing the convenience of using the equipment.

[0026] Furthermore, two sets of locking blocks 10 are fixedly installed on the left and right sides of both ends of the flow channel 4. The width of the two sets of locking blocks 10 is adapted to the spacing between the insertion fixing plates 2. The locking blocks 10 are inserted between the insertion fixing plates 2. This structure allows the flow channel 4 to be fixed with the water flow baffle 1, increasing the convenience and stability during installation.

[0027] Furthermore, fixing straps 11 are fixedly installed at both ends of the protective net 5. Three sets of fixing rings 12 are fixedly installed in an array on the fixing straps 11. The size of the fixing rings 12 is adapted to the size of the fixing spikes 3. The fixing rings 12 on the rear side are tightly attached to the lower side of the limiting block 9, and the fixing rings 12 on the front side are inserted into the lower side of the fixing spikes 3. This structure allows the protective net 5 to be stably installed between the water flow baffles 1, and this installation method allows the protective net 5 to be tightly attached to the ground, thereby completing the solidification of the ground.

[0028] Working principle: In use, the locking block 10 is locked between the insertion fixing plate 2, then the water flow baffle 1 is placed on the ground, the insertion fixing plate 2 is inserted into the soil for fixation, the fixing strap 11 is placed on the water flow baffle 1, the fixing spike 3 is inserted into the fixing groove 7 so that the fixing spike 3 penetrates into the soil and the limiting block 9 abuts against the fixing ring 12, the front fixing strap 11 is placed under the fixing spike 3, and then the front water flow baffle 1 is fixed. At this time, the equipment is installed. When the tide comes in, the water flow baffle 1 can block the direct impact of the tide on the soil and vegetation. When the tide recedes, the water flow baffle 1 can block the flow of water and, under the guidance of the guide plate 8, enter the guide channel 4 for discharge. The above is the complete working principle of this utility model.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
