Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to a biological interception device for river ecological restoration. Background Art

[0002] With the acceleration of industrialization and the continuous improvement of urbanization, river ecosystems have suffered severe damage. Problems such as water pollution, biodiversity loss, and degradation of riverine ecological environments are becoming increasingly prominent, making the need for river ecological restoration particularly urgent. Traditional methods of river ecological restoration include physical, chemical, and biological remediation, among which biological remediation has attracted much attention due to its environmentally friendly, economical, and sustainable characteristics. Biological interception devices, as an effective bioremediation technology, utilize the adsorption, absorption, and transformation effects of aquatic plants by setting up interception facilities within the river channel to purify water quality and restore the ecosystem.

[0003] Traditional biological interception devices typically involve driving piles into the riverbed and then fixing a retaining net to the piles to intercept aquatic plants. This process is not only large-scale and difficult to construct, but also wastes a significant amount of manpower and resources. Furthermore, because aquatic plant growth is seasonal, different types of plants need to be replaced in different seasons to maintain optimal restoration results. Traditional biological interception devices require extensive dredging and replanting of aquatic plants during replacement, increasing maintenance costs and labor intensity. Therefore, we propose a biological interception device for river ecological restoration to address these problems. Utility Model Content

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0028] This application provides a biological interception device for river ecological restoration, which is mainly used to solve the problems of large engineering workload and high construction difficulty in the existing technology, which requires a lot of manpower and material resources. In addition, due to the seasonal growth of aquatic plants, different types of plants need to be replaced in different seasons to maintain the best restoration effect. When replacing aquatic plants, traditional biological interception devices require a lot of salvaging and replanting work, which increases maintenance costs and labor intensity. The following technical solutions are provided, which will be combined with Figures 1-4 Give detailed instructions:

[0029] A biological interception device for river ecological restoration, comprising:

[0030] Piles 1 are inserted at intervals on the bank of the river;

[0031] Guide rope 2 is set between two opposite stakes 1, and the length of guide rope 2 is adjustable;

[0032] A reeling mechanism 3 is provided on the pile 1 and is used to reel in the guide rope 2;

[0033] Planting trough 4 is set on the riverbank and between two guide ropes 2. A nylon net 401 is set in the middle of the bottom of the planting trough 4, and columnar floats 404 are set on the outer walls of the other two sides of the planting trough 4.

[0034] Connector 5 is located at the four corners of the planting trough 4. Connector 5 is used to prevent the planting trough 4 from detaching from the guide rope 2.

[0035] The limiting member 6 is provided on the guide rope 2 and is used to limit the front and rear positions of the planting trough 4 .

[0036] Workflow Description:

[0037] The first step is to insert piles 1 at intervals on both banks of the river to ensure that the piles 1 are stable;

[0038] Step 2: Set the guide rope 2 between two opposite stakes 1, and adjust the length of the guide rope 2 by the winding mechanism 3 to adapt to the width and depth of the river channel;

[0039] The third step is to set up planting troughs 4 on the riverbank and restrict the planting troughs 4 between two guide ropes 2 using connectors 5 and limiting components 6.

[0040] The fourth step is to plant suitable aquatic plants in planting trough 4. Change the types of plants according to the season. When changing aquatic plants, planting trough 4 can be removed, cleaned, and then new aquatic plants can be planted.

[0041] Working principle:

[0042] The biological interception device constructs a stable frame structure through the insertion piles 1 and the guide ropes 2, and the planting troughs 4 are suspended between the guide ropes 2 to form a suspended ecosystem. Aquatic plants grow in the planting troughs 4, and their roots are in contact with the water body through the nylon mesh 401, absorbing nutrients and pollutants in the water. At the same time, the stems and leaves of the plants are exposed to the water surface to carry out photosynthesis, further purifying the air. As the water flows, the suspended matter and pollutants in the water are adsorbed, absorbed and transformed by the plants, thereby achieving the purpose of purifying the water quality.

[0043] like Figure 2 As shown, in some embodiments, the winding mechanism 3 includes an annular float 301 slidably mounted on the pile 1 and a winding wheel 302. The winding wheel 302 is located above the annular float 301, and the guide rope 2 is wound in the wheel groove of the winding wheel 302. More specifically, the annular float is slidably mounted on the pile 1. This design allows it to move up and down on the pile 1 to adapt to changes in water level. The winding wheel 302 is located above the annular float 301 and is the core part of the winding mechanism 3. A wheel groove is provided on the winding wheel 302 for winding the guide rope 2. By rotating the winding wheel 302, the guide rope 2 can be retracted and released. The guide rope 2 is wound in the wheel groove of the winding wheel 302. The length of the guide rope 2 can be adjusted according to actual needs to adapt to different river conditions.

[0044] like Figure 2As shown, in some embodiments, a female hook and loop fastener 303 is adhered to the top of the annular float 301, and a female hook and loop fastener that cooperates with the female hook and loop fastener 303 is provided at the bottom of the winding reel 302. More specifically, the female hook and loop fastener 303 and the female hook and loop fastener are quickly connected by mutual adsorption. When they are tightly attached, they can form a stable whole, effectively preventing the winding reel 302 and the annular float 301 from separating under the impact of water flow. In addition, after the guide rope 2 is adjusted to a suitable length, the side of the guide rope 2 closest to the winding reel 302 is placed between the annular float 301 and the winding reel 302. The adsorption properties of the female hook and loop fastener 303 and the female hook and loop fastener are used to fix the guide rope 2 between the two, which can prevent the guide rope 2 from continuing to be wound and unwound, ensuring the stability of the planting trough 4.

[0045] like Figure 3 As shown, in some embodiments, the connector 5 includes a connecting rope 501 connected to the corners of the planting trough 4, and the other end of the connecting rope 501 is provided with a self-locking buckle 502. More specifically, one end of the connecting rope 501 is connected to the four corners of the planting trough 4, and the other end is connected to the guide rope 2 via the self-locking buckle 502. This design allows the planting trough 4 to be stably suspended on the guide rope 2, while allowing the planting trough 4 to slide freely on the guide rope 2 to adapt to changes in water flow. The self-locking buckle 502 is a quick-connect and release device, typically used to fix one end to the guide rope 2 and the other end to the connecting rope 501. The design of the self-locking buckle 502 allows for quick adjustment or replacement of the planting trough 4 without disassembling the entire device.

[0046] like Figure 3 As shown, in some embodiments, the limiting member 6 includes an externally threaded tube 601 and a sleeve 602 slidably sleeved on the surface of the guide rope 2. One end of the externally threaded tube 601 is fixed with a limiting disc 603, and its other end has a ring array of strip-shaped notches 6011. The sleeve 602 is threadedly connected to the externally threaded tube 601, and its end away from the externally threaded tube 601 is tapered. More specifically, rotating the limiting disc 603 causes the externally threaded tube 601 and the sleeve 602 to engage. As the threaded connection deepens, the end of the externally threaded tube 601 with the strip-shaped notch 6011 gradually enters the tapered section of the sleeve 602. At this time, the strip-shaped notch 6011 of the externally threaded tube 601 begins to converge, thereby clamping and fixing the guide rope 2. By adjusting the position of the limiting disc 603, it can be ensured that the limiting disc 603 is fixed in the required position, thereby effectively limiting the position of the planting trough 4.

[0047] like Figure 4 As shown, in some embodiments, the planting trough 4 is constructed with fences 402 on both sides perpendicular to the river direction. More specifically, the fences 402 are perpendicular to the river direction. This construction method allows the planting trough 4 to better adapt to the river's flow direction and reduces the impact and erosion of the water flow on the planting trough 4.

[0048] like Figure 4 As shown, in some embodiments, sleeves 403 are fixed at the four corners of the planting trough 4, and the ends of the cylindrical float bladders 404 are embedded in the sleeves 403. More specifically, when the planting trough 4 is placed on the water surface, the cylindrical float bladders 404 provide sufficient buoyancy to support the planting trough 4 and the plants therein. The structure of the sleeves 403 and cylindrical float bladders 404 is relatively simple, making them easy to install and maintain.

[0049] like Figure 1 As shown, in some embodiments, the bottom end of the stake 1 is tapered, and a pressing plate 101 is fixed to its top. More specifically, when inserting the stake 1, the user first aligns the tapered bottom end of the stake 1 with the soil surface and then firmly presses the pressing plate 101. Due to the tapered bottom design, the stake 1 can more easily penetrate the soil surface and penetrate deeper into the soil. At the same time, the pressing plate 101 provides a stable support point for the user, making it easier to apply force.
