Description

Technical Field

[0001] This utility model relates to the field of wetland ecological protection technology, and more specifically, it relates to an ecological embankment for wetland ecological protection. Background Technology

[0002] In existing wetland ecological protection work, cofferdams are key facilities for delineating protected areas, regulating the water environment, and assisting in ecological restoration. Their core requirement is to balance structural stability and ecological compatibility.

[0003] Traditional wetland dikes often use monolithic rigid structures, such as concrete pouring or splicing metal plates of fixed specifications. These structures have fixed shapes and are difficult to adjust flexibly according to the shape and range of the wetland protection area. They are extremely unsuitable for irregular terrain. At the same time, rigid structures often block the water exchange and biological migration channels between areas, leading to the break of the ecological chain inside the wetland. Furthermore, the hard surface is easily eroded by water flow and is prone to collapse and damage after long-term use.

[0004] Most existing cofferdams only have basic containment functions and lack targeted water purification and flow buffering mechanisms. When wetland water flows fluctuate, the direct impact on the side walls of the cofferdam can easily cause soil erosion along the shoreline, while unbuffered water flow can also impact aquatic vegetation and benthic organisms on the inner side of the cofferdam.

[0005] In addition, the connection between individual cofferdams is mostly made by bolted splicing, which is complicated to install and disassemble, and it is difficult to guarantee the sealing and stability of the splice. Utility Model Content

[0006] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides an ecological dike for wetland ecological protection, so as to solve the technical problem mentioned in the background art of the lack of targeted water purification and water flow buffering mechanisms in the prior art.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: An ecological embankment for wetland ecological protection includes a support frame. Symmetrical grooves are provided at both ends of the front side of the support frame. A screw is rotatably installed through one groove, and a sliding rod is fixedly installed through the other groove. Lifting blocks are provided on both the screw and the sliding rod. The screw is threadedly connected to the lifting blocks, and the sliding rod is slidably connected to the lifting blocks. A baffle is provided between the two lifting blocks, and the baffle is adapted to and slidably connected to the support frame. A handle is provided at the upper end of one of the grooves, and one end of the screw is connected to the handle. A purification component is provided at the rear end of the support frame, and combined components are provided at both ends of the support frame.

[0008] The present invention is further configured such that symmetrical sliding grooves are provided at both ends of the rear side of the support frame, the purification component includes an installation strip and a buffer net, the installation strip passes through the sliding groove and is slidably connected to it, the buffer net is between two installation strips, the side wall of the sliding groove is provided with multiple sliding holes, the lower end of the side wall of the installation strip is provided with an installation hole, the sliding hole and the installation hole can coincide, and a pin is provided in the sliding hole and the installation hole to facilitate cleaning, replacement or maintenance of the buffer net.

[0009] The present invention is further configured such that the combined component includes a slide rail, a slide bar, and a fixing pin. The slide rail is on one side wall of the support frame, and the slide bar is on the other side wall of the support frame. The slide bar passes through the slide rail and is slidably connected to it. An auxiliary hole is provided on the upper side of the slide rail and the slide bar. The fixing pin passes through the auxiliary hole and is threadedly connected to it. A limit block is provided on the bottom wall of the slide rail to realize the rapid splicing of multiple sets of cofferdams. The limit block positioning avoids splicing misalignment.

[0010] The present invention is further configured such that the bottom wall of the support frame is provided with a plurality of insertion blocks, and the insertion blocks are provided with evenly distributed threads. The insertion blocks penetrate deep into the wetland bottom mud to achieve stable fixation. The threaded structure increases the friction with the bottom mud, preventing the cofferdam from collapsing or shifting.

[0011] The present invention is further provided with a handle at the upper end of the buffer net, and a silicone sleeve on the handle, which facilitates the lifting and disassembly of the buffer net and makes operation easier.

[0012] The present invention is further configured such that the buffer net has a double-layer structure, and the lower side of the two buffer nets is filled with a layer of crushed stone. The crushed stone layer has a uniform particle size and a smooth surface, which enhances the interception and buffering effect and weakens the impact of water flow on the cofferdam.

[0013] The present invention is further configured such that the support frame is made of stainless steel, the surface is sandblasted to remove rust, and the outer side is coated with an eco-friendly anti-corrosion coating to improve the structural strength and rust resistance.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides an ecological dike for wetland ecological protection, which has the following beneficial effects: 1. When the handle is turned to drive the screw to rotate, the lifting block drives the baffle to rise and fall synchronously under the combined action of the screw thread and the guide of the slide rod. When the baffle rises, its bottom forms an adjustable opening with the bottom of the wetland. The size of the opening changes precisely with the lifting height, which can not only meet the needs of water exchange between different areas of the wetland, but also adjust the water flow speed and flow rate by controlling the opening size, so as to avoid the water flow being too fast to scour the shoreline or too slow to cause the water to stagnate. When the baffle falls to fit the bottom surface, the opening closes, which can realize the isolation of the area and meet the sealing needs in specific scenarios such as water quality restoration and biological protection.

[0015] 2. After the threaded insertion block on the bottom wall of the support frame penetrates into the wetland sediment, the threaded structure greatly increases the contact friction with the sediment, effectively preventing the cofferdam from collapsing or shifting when impacted by water flow or when the sediment settles. It can also achieve stable installation without complicated fixing equipment, and is suitable for wetland sediment environments with different degrees of softness and hardness.

[0016] 3. The buffer net, through the sliding cooperation of the installation strip and the chute, can be adjusted in position according to the water level. It can be fixed by inserting the pin, ensuring that the buffer net is always at the optimal water flow interception height. The buffer net can effectively weaken the impact of water flow on the side wall of the cofferdam, reduce the erosion of the shoreline caused by water flow, and intercept suspended impurities in the water, thus initially purifying the water quality. In addition, the structure of the buffer net does not completely block water exchange, ensuring the flow of water between areas and the migration channels of small aquatic organisms, avoiding the ecological chain breakage problem caused by traditional rigid cofferdams, and taking into account both enclosure protection and ecological compatibility.

[0022] Please see Figure 1-5 An ecological embankment for wetland ecological protection includes a support frame 1. Symmetrical grooves are provided at both ends of the front side of the support frame 1. A screw 2 is rotatably installed through one groove, and a sliding rod 3 is fixedly installed through the other groove. Lifting blocks 4 are provided on both the screw 2 and the sliding rod 3. The screw 2 and the lifting blocks 4 are threadedly connected, and the sliding rod 3 and the lifting blocks 4 are slidably connected. A baffle 5 is provided between the two lifting blocks 4, and the baffle 5 is adapted to and slidably connected to the support frame 1. A handle 6 is provided at the upper end of one of the grooves, and one end of the screw 2 is connected to the handle 6. A purification component is provided at the rear end of the support frame 1, and combined components are provided at both ends of the support frame 1.

[0023] The support frame 1 has symmetrically arranged sliding grooves 7 at both ends of its rear side. The purification component includes an installation strip 8 and a buffer net 9. The installation strip 8 passes through the sliding groove 7 and is slidably connected to it. The buffer net 9 is between two installation strips 8. The side wall of the sliding groove 7 is provided with a plurality of sliding holes 10. The lower end of the side wall of the installation strip 8 is provided with an installation hole. The sliding hole 10 and the installation hole can coincide. The sliding hole 10 and the installation hole are provided with a pin 11.

[0024] The bottom wall of the support frame 1 is provided with a plurality of insertion blocks 17, and the insertion blocks 17 are provided with evenly distributed threads.

[0025] In this embodiment, the foundation is first fixed by placing the support frame 1 at a predetermined position in the wetland. The threaded insertion block 17 on its bottom wall is pressed into the bottom mud, and the threads enhance the friction with the bottom mud, ensuring that the support frame 1 stands firmly and is not washed away by the water flow. Then, the water flow is adjusted by raising and lowering the baffle 5. The operator turns the handle 6 at the top of the groove, which drives the screw 2 in the groove to rotate. Since the screw 2 is threadedly connected to the lifting block 4 and the slide bar 3 restricts the lifting block 4 to slide only up and down, the rotation of the screw 2 will drive the lifting block 4 to drive the baffle 5 to rise or fall synchronously. When the baffle 5 rises, an opening is formed between its bottom and the bottom surface of the wetland. The size of the opening changes with the rising height, and the water flow can flow through the opening, realizing the conduction and flow regulation of the water flow. When the baffle 5 falls to fit the bottom surface, the opening closes, which can block the water flow or reduce leakage. According to the wetland protection requirements (such as separating areas and controlling water exchange), the height of the baffle 5 is adjusted to a suitable opening size, and then the handle 6 is stopped. The self-locking characteristic of the thread fixes the position of the baffle 5.

[0026] More specifically, the purification components are then assembled to assist in water quality protection. The mounting strip 8 is inserted into the groove 7 on the back of the support frame 1 and slid until the buffer net 9 can cover the water flow opening area. The mounting hole of the mounting strip 8 is aligned with the sliding hole 10 of the groove 7. The pin 11 is then inserted to fix it. At this time, the buffer net 9 is located on the path of the water flow, which can intercept impurities in the water and weaken the impact of the water flow. At the same time, it does not hinder the passage of small organisms, thus taking into account both purification and ecological circulation. If it is necessary to expand the control range, multiple sets of devices can be spliced ​​by combining components. The sliding strip 13 of one set of support frame 1 is inserted into the sliding rail 12 of another set and slid to the limit block 16 for positioning. After aligning with the auxiliary hole 15, the fixing nail 14 is screwed in for reinforcement, so that multiple sets of devices are connected as a whole. During use, if it is necessary to change the water flow, the handle 6 is turned again to adjust the height of the baffle 5.

[0027] Please see Figures 1-5 As one embodiment of the combined component: the combined component includes a slide rail 12, a slide bar 13, and a fixing pin 14. The slide rail 12 is on one side wall of the support frame 1, and the slide bar 13 is on the other side wall of the support frame 1. The slide bar 13 passes through the slide rail 12 and is slidably connected to it. The upper side of the slide rail 12 and the slide bar 13 is provided with an auxiliary hole 15. The fixing pin 14 passes through the auxiliary hole 15 and is threadedly connected to it. The bottom wall of the slide rail 12 is provided with a limit block 16.

[0028] Specifically, take two sets of cofferdams, align the sliding strip 13 on the side wall of one set of support frame 1 with the slide rail 12 on the side wall of the other set of support frame 1, and insert it. The sliding strip 13 slides down the slide rail 12 until it contacts the limiting block 16 on the bottom wall of the slide rail 12. The limiting block 16 restricts the sliding strip 13 from sliding excessively and positions it to ensure that the two sets of cofferdams are aligned. Insert the fixing nail 14 through the auxiliary hole 15 aligned on the slide rail 12 and the sliding strip 13, tighten the fixing nail 14, and use the threaded connection to make the slide rail 12 and the sliding strip 13 tightly fixed, thus completing the splicing of the two sets of cofferdams. Repeat the above steps to splice and fix multiple sets of cofferdams in sequence by using the sliding strip 13 and the slide rail 12 to form the required length of enclosure area. When disassembling, unscrew the fixing nail 14 in the opposite direction and pull out the sliding strip 13 to separate them.

[0029] Please see Figures 1-5 As one embodiment of the handle 18: the upper end of the buffer net 9 is provided with a handle 18, the handle 18 is provided with a silicone sleeve, the buffer net 9 has a double-layer structure, the lower side of the two layers of buffer net 9 is filled with a gravel layer, the gravel layer has a uniform particle size and a smooth surface.

[0030] Specifically, hold the handle 18 with the silicone sleeve at the top of the buffer net 9, align the mounting strips 8 on both sides of the buffer net 9 with the grooves 7 on the back of the support frame 1, insert and slide them.

[0031] Please see Figures 1-5 As one implementation of the anti-corrosion coating: the support frame 1 is made of stainless steel, the surface is sandblasted to remove rust, and its outer side is coated with an eco-friendly anti-corrosion coating.

[0032] Specifically, the anti-corrosion coating and stainless steel material ensure that the device can be used for a long time in wet environments.

[0033] In summary, when using the overall equipment: First, place the support frame 1, made of stainless steel, sandblasted to remove rust and coated with an eco-friendly anti-corrosion coating, vertically at the predetermined enclosure position in the wetland. After aligning it with the bottom sediment, press the support frame 1 downwards so that the multiple threaded insertion blocks 17 on the bottom wall gradually penetrate into the bottom sediment. The threaded structure increases the friction with the bottom sediment, ensuring that the support frame 1 stands firmly and preventing displacement caused by subsequent water flow impact.

[0034] Next, adjust the height of the baffle 5 according to the wetland water flow control requirements to control the opening size. The operator holds the handle 6 at the top of the groove and rotates it clockwise or counterclockwise, which drives the screw 2 in the groove to rotate synchronously. Since the screw 2 and the lifting block 4 are threadedly connected, and the slide rod 3 forms a longitudinal guide limit for the lifting block 4, when the screw 2 rotates, it will drive the lifting block 4 to slide up and down along the slide rod 3, thereby driving the baffle 5 between the two lifting blocks 4 to rise and fall synchronously along the support frame 1.

[0035] When it is necessary to increase the water flow rate, turn the handle 6 clockwise to raise the baffle 5, forming an opening between its bottom and the bottom of the wetland. The higher the baffle 5 is raised, the larger the opening and the more water can pass through. When it is necessary to reduce the water flow rate or close off an area, turn the handle 6 counterclockwise to lower the baffle 5, and the opening will shrink accordingly until the baffle 5 is in contact with the bottom surface to achieve complete closure. After the position of the baffle 5 is adjusted, the thread self-locking characteristic of the screw 2 and the lifting block 4 can fix the height of the baffle 5 without the need for an additional locking structure.

[0036] Then, the purification components are assembled to fit the water flow opening. The operator holds the handle 18 with a silicone sleeve on the upper end of the buffer net 9, aligns the mounting strips 8 on both sides of the buffer net 9 with the sliding grooves 7 at both ends of the rear side of the support frame 1, and inserts them. The mounting strips 8 are slid up and down along the sliding grooves 7 to adjust the height of the buffer net 9, ensuring that the buffer net 9 can completely cover the water flow opening area below the baffle 5.

[0037] When the mounting hole on the side wall of the mounting strip 8 coincides with the corresponding sliding hole 10 on the side wall of the slide groove 7, insert the pin 11 into the coincident hole to complete the fixing of the mounting strip 8 and the buffer net 9. At this time, when the water flows through the opening, the double-layer buffer net 9 first intercepts suspended impurities in the water and weakens the impact force of the water flow. The smooth gravel layer on the lower side of the buffer net 9 further disperses the impact force of the water flow, preventing the water flow from directly washing the support frame 1. Moreover, the gaps between the gravel can provide migration and habitat channels for small aquatic organisms, taking into account purification, protection and eco-friendliness.

[0038] If it is necessary to expand the control range of the enclosure, multiple sets of devices can be spliced ​​together by combining components. Take another set of cofferdams, align the sliding strip 13 on the side wall of its support frame 1 with the slide rail 12 on the side wall of the fixed cofferdam support frame 1 and insert it. The sliding strip 13 slides down the slide rail 12 until it contacts the limiting block 16 on the bottom wall of the slide rail 12. The limiting block 16 can prevent the sliding strip 13 from sliding excessively and ensure that the two sets of cofferdams are aligned. When the slide rail 12 and the auxiliary hole 15 on the sliding strip 13 coincide, the fixing nail 14 is passed through the hole and tightened clockwise. The sealing and stability of the splicing point are enhanced by the threaded connection. Repeat the above operation to splice multiple sets of cofferdams into an enclosure area of ​​the required length. The height of the baffle 5 of each cofferdam can be uniformly adjusted to achieve large-area coordinated control of water flow.

[0039] During use, if the water level changes or the water flow requirement changes, simply turn the handle 6 to adjust the height of the baffle 5. If the buffer net 9 becomes clogged, pull out the pin 11, hold the silicone sleeve handle 18 and pull up the installation strip 8 to remove the buffer net 9. Clean or replace it and reinstall it. After the enclosure task is completed, turn the fixing nail 14 counterclockwise to disassemble multiple sets of cofferdams, lift the support frame 1 upwards to detach the insertion block 17 from the bottom mud, clean all parts and store them. The anti-corrosion coating and stainless steel material of the support frame 1 can ensure that it can be used for a long time in the wet environment and is not easy to rust.

[0040] In all the solutions mentioned above, the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
