Description

Technical Field

[0001] This utility model belongs to the field of ecological water-retaining dam technology, specifically a porous ecological water-retaining dam. Background Technology

[0002] Traditional dams are typically constructed using rigid materials such as concrete, resulting in relatively enclosed structures that disrupt the continuity of river ecosystems. This can lead to the disruption of migration routes for aquatic organisms such as fish, affecting their reproduction and survival. Simultaneously, it alters the natural flow of water, causing changes in the hydrological characteristics of the river upstream and downstream, negatively impacting the surrounding ecological environment and biodiversity.

[0003] At the same time, an ecological diversion dam with announcement number CN221255389U is disclosed, including a dam body, a main flood discharge hole in the middle of the bottom of the dam body, a secondary flood discharge hole on the dam body on the left and right sides of the main flood discharge hole, the diameter of the secondary flood discharge hole is smaller than that of the main flood discharge hole, and multiple water discharge holes are arranged from bottom to top on the dam body above the secondary flood discharge holes.

[0004] The aforementioned ecological diversion dam, during its use, rapidly discharges water through its porous structure. However, when floods arrive, the impact force of the flood is significant, and the porous structure cannot quickly divert the flow, causing water to overflow the dam structure and posing a risk of flood spread. At the same time, due to the lack of a buffer structure or the need for a dynamic or fixed structure to resist the impact, the dam body suffers strong impact damage, affecting its service life.

[0005] Therefore, a porous ecological water-retaining dam is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a porous ecological water-retaining dam with a buffered porous interception plate structure. This structure can fold and rotate on its own based on the impact of water flow, thus buffering the impact of the water flow and forming a larger porous interception structure for efficient drainage.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a porous ecological water-retaining dam, comprising an interception body, a dam body being stacked on the surface of the interception body, a fixing frame being fixedly mounted on the inclined surface of the dam body, a guide frame being fixedly mounted on the outer side of the fixing frame, and a porous component being provided inside the guide frame;

[0008] The porous assembly includes a porous interceptor plate that rotates with the fixed frame. The surface of the porous interceptor plate has multiple holes, and an interceptor net is provided on one side of the porous interceptor plate at the end. The surface of the interceptor net has mesh holes.

[0009] Preferably, a connecting block is fixedly provided on one side of the porous interceptor plate, and a horizontal shaft is rotatably provided through the interior of adjacent connecting blocks.

[0010] Preferably, a limiting frame is attached to the surface of the interception net, and a floating frame that rotates with the horizontal axis is fixed at the bottom of the limiting frame.

[0011] Preferably, the limiting frame has a bolt that is inserted into the intercepting net through its interior, and a nut that fits into the intercepting net is spirally provided on the outside of the bolt.

[0012] Preferably, the floating frame is made of hollow polyethylene material.

[0013] Preferably, the porous interceptor plate has three or more of them, and the connecting blocks are rotatably connected to the horizontal axis.

[0014] Preferably, the adjacent porous interceptor plates have a rotation range of 0° to 90° and are arranged in an alternating folding configuration.

[0015] Preferably, a float is fixedly provided at the bottom end of the guide frame.

[0016] Preferably, the inner wall of the fixing frame is provided with a guide groove, and a guide shaft that rotates with the end is slidably provided inside the guide groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model utilizes a porous interception plate structure designed to work in conjunction with a porous assembly. When a flood occurs, the water flow impacts the interception net structure, causing the porous interception plate to deflect and fold into a folded shape. With each wave of water flow, the plate continuously shifts and returns to its original deflected state. ， It provides a reverse thrust, forming water and water thrust, reducing the impact on the dam body, protecting the dam body, and the porous shape can provide a more natural and suitable habitat for organisms, promoting the development of biodiversity. The purpose of designing a porous structure is to provide a reverse thrust, forming water and water thrust, reducing the impact on the dam body, protecting the dam body, and the porous shape can provide a more natural and suitable habitat for organisms, promoting the development of biodiversity.

[0019] 2. This utility model, through the guide frame and guide shaft structure, can control the stable movement of the perforated interceptor plate inside the guide groove of the fixed frame, avoiding the problem of rotational deviation of the perforated interceptor plate.

[0027] 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.

[0028] The following describes an embodiment of this utility model based on its overall structure.

[0029] like Figures 1 to 4 As shown, this utility model provides a porous structure ecological water-blocking dam, including an interception body 1, a dam body 2 stacked on the surface of the interception body 1, a fixing frame 3 fixed on the inclined surface of the dam body 2, a guide frame 4 fixed on the outside of the fixing frame 3, and a porous component 6 inside the guide frame 4.

[0030] The porous assembly 6 includes a porous interceptor plate 61 that rotates with the fixed frame 3. The surface of the porous interceptor plate 61 has multiple holes. An interceptor net 68 is provided on one side of the porous interceptor plate 61 at the end. The surface of the interceptor net 68 has mesh holes that allow water to pass through.

[0031] In a further embodiment, a connecting block 63 is fixedly provided on one side of the porous interceptor plate 61, and a horizontal shaft 62 is rotatably provided inside the adjacent connecting block 63. The horizontal shaft 62 rotates in conjunction with the connecting block 63 to control the deflection of the porous interceptor plate 61.

[0032] The surface of the interception net 68 is fitted with a limiting frame 65, and the bottom end of the limiting frame 65 is fixed with a floating frame 64 that rotates with the horizontal axis 62, so that the limiting frame 65 provides a fixed position.

[0033] The limiting bracket 65 has a bolt 66 that is inserted into the interception net 68. The bolt 66 has a nut 67 that fits into the interception net 68 on the outside. The bolt 66 is used to quickly fix the interception net 68.

[0034] The float 64 is made of hollow polyethylene material, providing buoyancy.

[0035] The perforated interceptor plate 61 has three or more of them, and is rotatably connected to the horizontal axis 62 by a connecting block 63. The number of perforated interceptor plates 61 can be modified according to the water flow rate.

[0036] The adjacent porous interceptor plates 61 have a rotation range of 0° to 90° and are staggered folded. The staggered structure can increase the overall thickness of the porous interceptor plates 61 after deflection, thus making them more resistant to floods.

[0037] A float 5 is fixedly installed at the bottom of the guide frame 4. The added float 5 structure can push the guide frame 4 to float.

[0038] The inner wall of the fixed frame 3 is provided with a guide groove 7, and a guide shaft 8 located at the end of the guide groove 7 is slidably provided inside the guide groove 7. The porous interceptor plate 61 moves stably inside the guide groove 7 through the guide shaft 8.

[0039] The working principle and process of a porous ecological water-retaining dam:

[0040] The bottom float 5 of the guide frame 4 provides buoyancy, causing the porous component 6 to rise and fall with the water level. When the water level changes, the float 5 drives the guide frame 4 to slide along the guide groove 7 on the inner wall of the fixed frame 3, ensuring that the porous component 6 is in an effective working position. The guide shaft 8 is connected to the end porous interceptor plate 61 and slides within the guide groove 7, limiting the movement trajectory of the porous component 6 and preventing it from shifting and swaying under the impact of water flow, thus ensuring structural stability. The porous interceptor plate 61 has multiple holes on its surface to intercept larger floating objects while allowing water flow. Multiple porous interceptor plates 61 are rotatably connected to the horizontal shaft 62 through connecting blocks 63. The porous interceptor plate 61 has a foldable structure. When the water level is low, it unfolds under gravity, expanding the interception area. When the water level rises or a flood occurs, the impact force of the water flow pushes the porous interceptor plate 61 to rotate around the horizontal axis 62, folding it up to 90° to reduce the water flow area, lower the flow velocity, and enhance flood control capabilities. An interception net 68 is installed on one side of the porous interceptor plate 61 at the end. Its mesh size is smaller than that of the porous interceptor plate 61, used to intercept fine floating debris and suspended particles, further purifying the water quality. At the same time, through deflection, it forms a reverse impact force with the waves of water flow, thereby reducing the impact of the water flow. The slow-flowing water impacts the dam body 2, thus providing more effective protection for its structure. The interception net 68 is fixed to the floating frame 64 via a limiting frame 65, bolts 66, and nuts 67, facilitating disassembly and replacement. The floating frame 64, made of hollow polyethylene, provides buoyancy to keep the interception net 68 below the water surface and is rotatably connected to the horizontal axis 62, allowing it to rotate synchronously with the porous interception plate 61. The dam body 2 is stacked on the surface of the interception main body 1, and its inclined fixing frame 3 provides an installation platform for the porous component 6 and constrains the sliding path of the guide frame 4 through the guide groove 7, supporting the entire water-retaining dam system and resisting water. As the water flows and waves impact the dam, carrying floating debris, the porous interceptor plate 61 first intercepts larger particles. The water continues to pass through the interception net 68, where fine particles are filtered out. The porous structure ensures unobstructed migration channels for aquatic organisms. The slow-moving water provides an attachment surface for microorganisms, promoting water purification. When the water level rises, the float 5 drives the guide frame 4 to slide upward along the guide channel 7, maintaining the relative position of the porous component 6 with the water surface. The impact of the water flow causes the porous interceptor plate 61 to fold, reducing the water passage area. As the water level drops, the float 5 sinks, and the porous interceptor plate 61 unfolds under gravity, restoring the interception area.

[0041] When debris accumulates on the interceptor mesh 68, it can be quickly replaced by removing bolts 66 and nuts 67. The multi-hole interceptor plate 61 features a modular design, facilitating the individual replacement of damaged parts and reducing maintenance costs.
