Description

Technical Field

[0001] This utility model mainly relates to the field of water purification technology, specifically a three-dimensional suspended water purification device based on the submerged plant of freshwater mussels. Background Technology

[0002] In the current field of water purification technology, traditional purification methods often rely on chemical agents or physical filtration devices. While these methods can improve water quality to some extent, they often suffer from high costs, complex operations, and the potential for secondary pollution. Especially in the purification of large bodies of water such as lakes and rivers, the efficiency and effectiveness of traditional methods often fall short of practical requirements.

[0003] In recent years, with the growing popularity of ecological and environmental protection concepts, water purification using biological methods has gradually become a research hotspot. Among these, freshwater mussels and submerged plants have attracted considerable attention due to their unique advantages in water purification. Freshwater mussels, through filter feeding, can effectively remove suspended solids, organic matter, and microorganisms from the water, thereby improving water quality. Submerged plants, on the other hand, can absorb and utilize nutrients such as nitrogen and phosphorus from the water while releasing oxygen, further promoting the ecological balance of the aquatic body. However, in practical applications, providing a stable and suitable attachment and growth environment for freshwater mussels and submerged plants has become a key factor restricting their widespread application. Therefore, a three-dimensional suspended water purification device based on freshwater mussels and submerged plants is proposed. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. It mainly provides a three-dimensional suspended water purification device based on river mussels and submerged plants, which solves the technical problem mentioned in the background art of providing a stable and suitable attachment and growth environment for river mussels and submerged plants.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A three-dimensional suspended water purification device based on submerged plants of freshwater mussels includes a support rod assembly and a net assembly. The support rod assembly is provided in two sets, and the two sets of support rod assemblies are connected by a traction rope. Several sets of floats are installed on the traction rope, and the traction rope is connected to the net assembly through a connecting line.

[0007] Preferably, the support rod assembly includes an insert rod with an open top, a pile body is slidably disposed inside the insert rod, and a positioning component for limiting the position is provided between the insert rod and the pile body.

[0008] Preferably, the traction rope is made of polyethylene rope, and the floats are equidistantly arranged on the outside of the traction rope.

[0009] Preferably, the net assembly includes a bag body, and the inside of the bag body is divided into several independent pocket cavities. An inlet is provided on the upper part of one side of each independent pocket cavity, and the inlet can be closed by a knotting assembly.

[0010] Preferably, the bag body can be made of polyethylene mesh.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By designing the net assembly into a structure containing several independent pockets, with each pocket made of polyethylene netting, the mesh size allows the roots of submerged plants to penetrate and grow while preventing disturbance by freshwater mussels. At the same time, the upper part of each pocket has an inlet that is closed by a knotted rope assembly, facilitating the release of freshwater mussel seedlings and submerged plants. It also allows for the separate hanging of freshwater mussels and submerged plants, forming a multi-level biological synergistic purification mode of "submerged plants absorbing nitrogen and phosphorus + freshwater mussels filtering suspended matter," thereby improving water purification efficiency.

[0013] By setting up two sets of support rod assemblies and adopting a sliding fit structure between the insert rod and the pile body in the support rod assembly, along with the conical opening cylinder and anti-slip contact layer of the positioning assembly, the extension length of the pile body in the insert rod can be adjusted according to the water depth data, thereby precisely controlling the suspension depth of the net bag assembly to meet the light requirements of different submerged plants. At the same time, the pressure ring deforms the conical opening cylinder and tightly fits the pile body, thereby limiting the position of the pile body and ensuring the stability of the device under the impact of water flow.

[0023] Please refer to the appendix carefully. Figure 1-3 A three-dimensional suspended water purification device based on submerged plants such as freshwater mussels is disclosed. The support rod assembly 1 comprises two sets, each including an insertion rod 101 with a pointed bottom for easy and quick insertion into a riverbed or lakebed substrate. The top of the insertion rod 101 is open, and a pile 102 is slidably mounted inside the insertion rod 101. A positioning assembly 103 for limiting positioning is provided between the insertion rod 101 and the pile 102. The positioning assembly 103 includes a pressure ring, and a conical opening cylinder is installed on one side of the pressure ring, which is slidably fitted onto the... An anti-slip contact layer is provided on the outer side of the pile body 102 and the inner side of the conical opening cylinder. A deformation opening is provided on one side of the conical opening cylinder. The conical opening cylinder can be made of stainless steel elastic metal alloy material. The elastic metal alloy material has good deformation recovery ability and corrosion resistance and can maintain stable performance over a wide temperature range. The anti-slip contact layer can be made of rubber, polyurethane or other high-friction synthetic materials. These materials have good elasticity and wear resistance and can provide stable friction to prevent relative sliding between the conical opening cylinder and the pile body 102.

[0024] Two sets of support rod assemblies 1 are connected by a towing rope 3. The towing rope 3 is made of polyethylene rope. A number of groups of PET floating balls 301 are installed on the towing rope 3. The floating balls 301 are arranged at equal intervals on the outer side of the towing rope 3. The outer diameter of the towing rope 3 is 10 - 16 mm, the breaking strength is ≥ 800 N, and it has excellent ultraviolet aging resistance. Its service life in natural water bodies can reach 5 - 8 years. The PET floating balls 301 are sleeved on the outer side of the towing rope 3 at equal intervals. The floating balls 301 are hollow spheres with a diameter of 10 - 15 cm, a wall thickness of 3 - 5 mm, and a density of 0.92 - 0.95 g / cm³. The buoyancy coefficient of a single floating ball 301 is ≥ 12 N. The distance between the floating balls 301 is set to 1.5 - 2.5 m according to the water depth and the weight of the net bag. The floating balls 301 are installed on the towing rope 3 through quick-release connectors, and the number of floating balls can be increased or decreased according to the water level change and the load of the net bag assembly 2 (such as the weight increase caused by the growth of mussels).

[0025] The towing rope 3 is connected to the net bag assembly 2 through a connecting line. The towing rope 3 is connected to the net bag assembly 2 through a detachable connecting line. The connecting line is made of polyethylene rope with a diameter of 5 - 8 mm, and the two ends are fixed to the towing rope 3 and the net bag assembly 2 respectively through metal shackles. The net bag assembly 2 includes a bag body 201. The bag body 201 is sewn with polyethylene mesh cloth with a pore diameter of 3 - 5 mm. The breaking strength of the mesh cloth is ≥ 200 N, and it has strong weather resistance. And several independent pocket cavities 202 are divided inside the bag body 201. An object inlet 203 with a diameter of 15 - 20 cm is opened at the upper part of the independent pocket cavity 202. A polyethylene rope loop is sewn at the edge of the object inlet 203, and it is quickly closed through a "slipknot + buckle" type knotting component. The rope head of the knotting component is provided with an anti-slip rubber grip for easy underwater operation.

[0026] Further explanation: The horizontal distance between adjacent independent pocket cavities 202 is ≥ 20 cm, forming a "field" - shaped separation to avoid local hypoxia or nutrient salt enrichment, ensuring a uniform growth environment for plants. The independent pocket cavity 202 is made of polyethylene mesh cloth with a pore diameter of 3 - 5 mm. The pore diameter can allow the fine branches of the roots of submerged plants with a diameter < 1 mm to penetrate and grow, and can block mussels with a body length > 2 cm. The bottom of the independent pocket cavity 202 for submerged plants is filled with ceramsite with a particle size of 5 - 10 mm or quartz sand with a thickness of 10 - 15 cm. The matrix porosity > 40% provides a rooting support for submerged plants and avoids the water turbidity caused by traditional soil filling. The inside of the independent pocket cavity 202 is set loosely to avoid restricting the growth of submerged plants in the later stage.

[0027] The specific operation process of this utility model is as follows: First, according to the measured water depth data, lift the pile body 102 upward, accurately adjust its extension length in the insertion rod 101, so that the distance from the top of the pile body 102 to the water surface precisely matches the hanging depth requirement of the net bag assembly 2, and the adjustment accuracy is controlled within ± 10 cm.

[0028] After adjusting to the required height, pressure is applied to the conical opening cylinder through the pressure ring, causing one end of the conical opening cylinder to slowly enter the inner side of the opening end of the insertion rod 101. Utilizing the deformation characteristics of the stainless steel elastic metal alloy material, its inner anti-slip contact layer is tightly attached to the outer side of the pile body 102. The friction force generated by elastic deformation and the metal recovery force achieve a double locking of the position of the pile body 102, ensuring that the pile body 102 does not loosen under the impact of water flow.

[0029] Then, the two sets of insertion rods 101 are simultaneously and vertically inserted into the underwater substrate at the designated location confirmed by the survey. The insertion depth is controlled at 50-100cm depending on the softness of the bottom. During insertion, the insertion rods 101 are kept vertical to avoid tilting and affecting the overall stability. After the insertion rods 101 are fixed, the net bag assembly 2 is suspended below the towing rope 3 through the polyethylene connecting line.

[0030] Open the inlet 203 of the net assembly 2, and release the organisms into the independent pocket 202 according to the ecological zoning principle. After the release is completed, close the inlet 203 with the "slip knot + buckle" rope assembly to ensure that the rope assembly is secure to prevent fish from entering and organisms from escaping, and finally complete the installation of the device and the deployment of organisms.

[0031] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
