Description

Technical Field

[0001] This utility model relates to the field of aquatic ecological protection technology, specifically to a combined experimental device for cultivating water-purifying plants and raising water-purifying benthic animals in water bodies of different depths. Background Technology

[0002] Human activities, such as agricultural fertilization, urban sewage discharge, and industrial wastewater discharge, result in large amounts of nutrients like nitrogen and phosphorus entering lakes. Eutrophication leads to a series of environmental problems, including water quality deterioration and ecosystem imbalance. Algal blooms cause a decline in dissolved oxygen, suffocating and killing fish and other aquatic organisms. Simultaneously, toxins and foul odors produced during algal decomposition affect drinking water safety and the lake's aesthetic value. While existing aquatic plants and benthic animals can remove nitrogen and phosphorus from lakes, protecting them from eutrophication, ecologists must study methods for removing excess nitrogen and phosphorus from the aquatic environment under artificial intervention when faced with excessive input. Therefore, researching the most efficient combinations of aquatic plants and benthic filter feeders for nitrogen and phosphorus removal is essential.

[0003] Using aquatic plants and animals alone to remove excess nitrogen and phosphorus from lakes is a common method. However, existing designs rarely incorporate aquatic plants and benthic animals as a whole for eutrophication removal. Most structures are either aquatic plant-feeding devices or benthic animal-feeding devices, and they cannot be adjusted for different water depths, reducing purification efficiency. Therefore, designing a water purification device that is adapted to river and lake environments, easy to install and disassemble, made of robust materials, and capable of long-term use is of great significance for research on the effectiveness of using a combination of aquatic plants and animals to remove nitrogen and phosphorus from eutrophic lakes.

[0043] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0044] Example 1:

[0045] This invention provides a combined experimental device for cultivating water-purifying plants and raising water-purifying benthic animals in water bodies of different depths, such as... Figures 1 to 5 As shown, the device includes a float plate 1 and multiple hanging cages 6. The hanging cages 6 are welded from stainless steel wire and provide space for aquatic benthic animals to live. The float plate 1 has a hole 11 in the center for cultivating aquatic plants. The bottom of the float plate 1 has one or more suspension points. Each suspension point is connected to one or more hanging cages 6 by a steel cable 4. When multiple hanging cages 6 are suspended below each suspension point, the multiple hanging cages 6 are connected in series from top to bottom by the steel cable 4 and are not at the same height. The multiple connected hanging cages form a hanging cage string.

[0046] In practical applications, the number of hanging cages 6 suspended below each suspension point can be flexibly designed according to the environmental water depth, the size of the hanging cages 6, and the actual needs of water purification. The hanging cages 6 below each suspension point are numbered from top to bottom. Hanging cages 6 with the same number below different suspension points can be placed at the same height or at different heights. Furthermore, the number of hanging cages 6 below different suspension points can be all the same, partially the same, or all different. Figure 1 Taking the design as an example, there are two hanging cages 6 below each of the three hanging parts, and the hanging cages 6 with the same number are set at the same height.

[0047] Specifically, the floating plate component 1 is composed of multiple floating plates 12 spliced ​​together, such as Figure 1 , Figure 2 , Figure 3 As shown, each float plate 12 has a lower half ring 2 at its bottom. Both the float plate component 1 and the lower half ring 2 are made of EVA ethylene-vinyl acetate copolymer. The float plate component 1 and the lower half ring 2 are integrally formed by integral pressing. The float plate 12 is a cuboid and appears as a square when viewed from above. The four corners of the float plate 12 are provided with arc grooves 121. Multiple float plates 12 are spliced ​​together to form the float plate component 1. After splicing, a hole 11 is formed in the center. The hole 11 is used to cultivate water purification plants.

[0048] like Figure 1 , Figure 5As shown, multiple hanging cages 6 suspended at different heights below each suspension point are connected by steel cables 4. The upper end of the first steel cable 4 from top to bottom is detachably fixed to the lower half-ring 2 of the float via a locking buckle 3, and the lower end of the steel cable 4 is connected to the upper end of the hanging cage 6. The upper ends of the other steel cables 4 are connected to the lower ends of the adjacent hanging cage 6 above, and the lower ends of the other steel cables 4 are connected to the upper ends of the adjacent hanging cage 6 below. In practical applications, the length of each steel cable 4 can be adjusted to adapt to river and lake environments of different depths.

[0049] like Figure 4 As shown, the hanging cage 6 includes a cage body 61 and a top cover 9. One end of the top cover 9 is rotatably engaged with one side of the top of the cage body 61 via a hinge 8. The connections between the hinge 8, the top cover 9, and the cage body 61 are all welded, enhancing the strength of the connection. The top cover 9 can be opened and closed by rotating around one side of the top of the cage body 61 via the hinge 8. The other end of the top cover 9 is equipped with a latch lock 7, which has two states: locked and unlocked. When the top cover 9 is closed, locking the latch lock 7 prevents the top cover 9 from leaving the other end of the cage body 61, i.e., the top cover 9 cannot be opened. When the latch lock 7 is unlocked, the top cover 9 can leave the other end of the cage body 61, i.e., it can be closed or opened. The design of the hinge 8 in this utility model facilitates the replacement of benthic animals.

[0050] like Figure 4 As shown, the top cover 9 is provided with a first connecting ring 5 at the upper end, and the cage body 61 is provided with a second connecting ring 10 at the lower end. The second connecting ring 10 is used to connect the upper end of the steel cable 4 located below the cage body 61, and the lower end of the steel cable 4 is connected to the first connecting ring 5 through a buckle 3.

[0051] Example 2:

[0052] This embodiment is a preferred example of Embodiment 1. In this embodiment, the float 12 is a cuboid with a length of 50cm, a width of 50cm, and a height of 10cm. Each of the four corners of the float 12 has an arc groove 121 with a radius of 10cm. After multiple floats 12 are spliced ​​together, there is a hole 11 with a radius of 10cm in the center. The hanging cage 6 is a cylindrical structure with a diameter of 25cm and a height of 15cm. The cage body 61 is made of 5mm 316 stainless steel mesh, and the bottom is welded to the cylindrical wall as one piece. The top cover 9 is also made of 5mm stainless steel mesh and has a diameter of 25cm.

[0053] Specifically, a first connecting ring 5 and a second connecting ring 10 are welded to the center of the bottom of the cage 61 and the center of the top cover 9, respectively. The first connecting ring 5 and the second connecting ring 10 are both made of 316 stainless steel.

[0054] Specifically, the first connecting ring 5 connects the lower end of the steel cable 4 via the locking buckle 3 to connect the hanging cage 6 to the floating plate 1, forming the upper-level benthic animal hanging device. The lower-level hanging device also uses the hanging cage 6, which is also connected to the steel cable 4 via the locking buckle 3 and the connecting ring 10 of the upper hanging cage 6 to form the lower-level hanging device.

[0055] In the specific implementation of this utility model, multiple hanging devices should first be connected to the locking buckle 4 via iron cable 3, and the locking buckle 4 should be connected to the lower half ring 2 of the float to make them a whole. Then, multiple or more whole units should be spliced ​​together into a whole experimental device that can simultaneously plant water purification plants.

[0056] In this invention, a floating plate 12 is connected to a hanging cage 6 to form a combination of plants and animals. The length of the steel cable 4 is freely adjustable to adapt to river and lake environments at different depths. The floating plate 12 is made of EVA (ethylene-vinyl acetate copolymer), the hanging cage 6 and its locking mechanism are made of 316 stainless steel, and the connecting device is a steel cable 4 covered with plastic coating. The complete experimental device in this invention uses readily available materials, has a simple structure, is easy to install and disassemble, and has a long designed service life. It can meet the requirements for conducting combined experiments on the cultivation of water-purifying plants and the hanging of benthic animals at different depths in rivers and lakes.
